Arista Networks, Inc. Stock

Welcome to the Third Quarter 2026 Arista Networks Financial Results Earnings Conference Call. During the call, all participants will be in a listen-only mode. [Operator Instructions] As a reminder, this conference is being recorded and will be available for replay from the Investor Relations section on the Arista website following this call. Mr. Rudolph Araujo, Arista's Head of Investor Advocacy, you may begin.

Good afternoon, everyone, and thank you for joining us. With me on today's call are Jayshree Ullal, Arista Networks Chairperson and Chief Executive Officer; and Chantelle Breithaupt, Arista Networks' Chief Financial Officer. This afternoon, Arista Networks issued a press release announcing its fiscal third quarter results for the period ending September 30, 2026. If you want a copy of this release, you can find it on our website.

During the course of this conference call, Arista Networks management will make forward-looking statements, including those relating to our financial outlook for the fourth quarter of the 2026 fiscal year, longer-term business model and financial outlook for 2027 and beyond. Our total addressable market and strategy for accessing those market opportunities across AI, campus, data center and other segments, inventory levels and management lead times, purchase commitments, component supply and product innovation, which are subject to the risks and uncertainties that we discuss in detail in our documents filed with the SEC specifically in our most recent Form 10-Q and Form 10-K and which could cause actual results to differ materially from those anticipated by these statements.

These forward-looking statements apply as of today, and you should not rely on them as representing our views in the future. We undertake no obligation to update these statements after this call. This analysis of our Q3 results and our guidance for Q4 2026 and FY 2027, and is based on non-GAAP financial measures and exclude stock-based compensation expense, intangible asset amortization and other nonrecurring items as well as the income tax effect of these non-GAAP exclusions, including the recognition of direct excess tax benefits associated with stock-based awards. A full reconciliation of our selected GAAP to non-GAAP historical results is provided in our earnings release. A reconciliation of our FY '27 non-GAAP guidance to the most directly comparable GAAP measures is not available without unreasonable effort. With that, I will turn the call over to Jayshree.

Thank you, Rudy, and welcome, everyone, to our third quarter 2026 earnings call. Arista just delivered a standout quarter of $3.66 billion in revenue, which is translating to our annual growth of 58.5%. This marks our largest ever year-over-year revenue growth in the history of being a public company.

Before we dive into the financial specifics, I would like to emphasize our rapid Arista 2.0 success. A strategy we embarked upon just 3 years ago. It has generated meaningful customer outcomes to become the central network nervous system for us. In the 2000 era, the industry had accepted a status quo, plagued by fragile, overly complex, disparate and vulnerable operating systems.

Arista pioneered the universal cloud network and the AI Spine architecture based upon our rock solid high-quality foundation of our differentiated EOS, that 1 network operating system with a published subscribed state and data-driven foundation has governed us with 5 As, Agile security, Automation, Availability, Analytics and AI principles.

By extending our single EOS operating system from the data center, all the way from the Universal Spine to many forms of edge lead functions, we deliver structural and secure network economy. Our Arista 2.0 transformation from data centers to centers of data can be characterized as the age of network intelligence, learning from vast repositories of stream data. It has driven our strategy across locations be a client to branch, to campus, the data to cloud and AI centers for our customers.

Based on our network data lake architecture, we offer our customers automated and conversational troubleshooting agentic companions. Devoid of manual hunting through text-heavy logs, our systems proactively begin identifying and isolating issues for network workloads, workflows and work streams. In 2026, the Network Centric acceleration is well underway. Our customers have increasingly cordless the back end and the front end of AI and data centers. Arista is long-chain standard-spaced Ethernet. Customers have welcomed our open approach to modernizing cloud campus data centers, WAN centers and now AI centers with a lower total cost of ownership.

Recently, we were recognized with the leader status from Forrester for the highest strength of innovation and data center portfolio. We were also recognized by Gartner Magic Quadrant leadership for campus wired and wireless and data center segments. As HNTKI models increase in realism, compute diversity and density, we have the choice of many more training and inference accelerators. The industry, we believe, is shifting from compute-centric vertical stack to a holistic network centric approach.

A risk is committed to unleashing and breaking down the barriers between compute and networking. Arista customers can now construct an open network platform capable of handling heterogeneous models and diverse accelerators at scale. Our ethylene portfolio of at least 25 switches for scale-up scale and scale across is optimally designed to improve XPU utilization, job completion and token latency for these intense training and inference workloads.

In October of 2026 at the Open Compute Project conference, Arista showcased our rack scale up designs partnering closely with several AI accelerators in field with our Arista network diagnostics layer. Based on E.SUN, Ethernet a scale-up, options. These include orthogonal designs, cable intensive back plans and heterogeneous cross-track designs co-designed with many of our partners, including ARM, Microsoft Maya, AMD's Helios, Qualcomm, Meta's MTIA and many more ahead.

We expect scale-up trials to begin in 2027, driving Ethernet to larger ratings of 126 to 144 within racks and across 1,000 across racks with production expected for scale-up in 2028. We are witnessing the migration from highly centralized training compute to disaggregated and distributed inference prefill and decode demanding much more intelligent networking and co-location of compute, storage and KB cash resources rather than simply focusing on raw feeds and speeds and flops of compute.

A well-designed network is becoming a foundational cornerstone for optimal token deficiency. Arista's decades of EOS engineering in both multiplanar and distributed model routing at scale, be it ARC address resolution protocols or fifth tables forward information base or access list with rapid reconversions comes to the rescue. Our ethylene products are inherently designed to actively understand parameters at a deep level. including latency and bandwidth profiles of multi-tenancy to intelligently staloads for optimal placement between local and remote domains.

The need for visibility into ports packages, flows, buffer utilization and part latency across the entire scale out and scale across fabric validates real AI system level performance to avoid idling of precious compute cycles. It assures immediate and network-wide insight to the root cause as well as rapid recovery of the AI system with smart system upgrades across millions of accelerators.

When we initially began this transformational AI journey, we spoke about 4 or 5 AI customers with approximately 50,000 to 100,000 NVIDIA GPUs, and in fact, we're largely staring at a proprietary network cycle such as InfiniBand. In 2026, we are in a super cycle of AI having already surpassed 100 ethylene customers. By the end of '27, we are forecasting greater than 10 gigawatts of deployment across 10 or more different types of compute accelerators. What a stark inflection in just 3 years.

Central to this AI super cycle is also the expansion of Arista AVA, our autonomous virtual assist to support efficient AI in the enterprise, by providing that open programmable interface within the U.S. and utilizing the model context protocol, MCP, AVA allows emerging AI agents to reason to interact with the network stack and perform advanced multi-domain event correlation across the entire enprise.

With exponential rise of generated AI attacks and the ever-increasing sidebar threats, securing the network is key and integral and our responsibility. I would like to invite Ken Duda, our Founder, President and CTO, to shed some light on this problem. Ken?

Thanks, Jayshree. It's hard to overstate the impact of AI on networking. First, a good news. AVA, which is Arista's autonomous virtual assistant, fueled by real-time data AVA is incredibly powerful. It seamlessly navigates networking and security infrastructure from campus to WAN to data center to cloud continuously monitoring and troubleshooting, isolating root causes without manual labor into tasks.

Having seen what AVA can do and imagine managing my own infrastructure without it, and I expect many of our customers will feel the same way. The bad news, of course, is the massive challenge AI poses for us and our customers by discovering and exploiting security vulnerabilities. This threat landscape demands secure and robust networking. Over the past few months, we've been collaborating with Anthropic, Google Open AI and many others to integrate new AI-enabled security capabilities from frontier models into our existing software security pipeline.

We are being invited early as a key infrastructure provider into partnerships like Project Class win, hold in AI-driven vulnerability discovery and assessment into our established security vulnerability management process. True network security has become a must-have, not a nice to have. And Arista's EOS operating system is the ideal architectural foundation based on 4 key principles. First, a single high-quality operating system.

Arista has maintained one of the lowest CDE counts less than 100 in the industry over the last 2 decades, while others are rising exponentially due in part to the simple fact that multiple networking operating systems tend to have more vulnerabilities than just one. Second, limiting vulnerability impact through process ization EOS keeps each software agent, management playing work controller planes architecturally separate from each other and also from hardware forwarding.

So traffic keeps moving even if there is a defect in 1 component. EOS state sharing architecture also resists lateral movement. So a defect in 1 component typically cannot be exploited to attack other agents within the switch. Third, we provide a seamless upgrade process. Process isolation also means that we can ship a targeted fix to the effective component and install the fix without a maintenance window or a network disruption.

And fourth, delivering a compliance dashboard to stay current. When a security advisory lens, Arista CloudVision brings real-time visibility to turns a stressful advisory day into a manageable one. In addition to providing secure switches, we also provide Zero Trust networking or ZTN technology to help our customers build a security structure. I'd especially like to highlight Macro Segmentation Services, or MSS, is ZTN feature allowing for dynamic security enforcement preventing undesired interactions among users, devices and applications.

Second, we provide Network Detection and Response, or NDR services that profile, analyze and proactively detect sophisticated security threats. And finally, once workload traffic leads the confines of the local data center, it becomes even more vulnerable to malicious actors. So we offer protection with wire speed ubiquitous link and total infliction native in every port with 0 performance sigation. I hope this was a helpful summary at how Arista is helping customers take advantage of AI while improving security to at the new challenges. Back over to you, Jayshree. .

Thank you, Ken. It was useful for me, too. With Arista's uncompromised ZTN approach, we can systematically address the security hazards and parabolic attacks. Our CVE count, a vulnerability count is often 10 to 50x better than alternatives. Our customer momentum this year has been significant to the enterprise, in the providers across data center campus and AI because they are addressing security proactively. I would like to invite Todd Nightingale, our President and Chief Operating Officer, to describe more about this. Over to you, Todd.

Thank you, Jayshree. We're seeing phenomenal growth across our enterprise business, driven by customers building mission-critical networks, which benefit from Arista's industry-leading quality and reliability. The entire industry response to AI-powered attack exposure, customers are motivated by the fact that keeping their infrastructure current with security updates will protect, segment and defend against vulnerabilities beyond the network. .

Arista on a strategic deal at an Asian web services company as they shifted their focus strategically on the speed, scale and resilience in the new AI era. Reliability was the key to the engagement as their teams are frustrated by long-standing quality issues with their existing vendor. Arista was able to demonstrate reliability and scalability while leveraging standards-based technology and a powerful e-VPN VXLAN architecture on our 100- and 400-gig platforms. This deployment will operate as the front end for their AI deployment moving forward. In the health care sector, leading hospitals are selecting Arista for strategic data center deployment. One important hospital group chose Arista is following an exhaustive Zero Trust working evaluation.

Their primary business goal was to protect sensitive patient data through advanced network segmentation while enabling seamless integration to cloud environments. Arista secured this win by delivering an automated high-performance fabric that perfectly aligned with their trust nothing verify everything security mandate. By centralizing routing on Arista's R3 spines, we provided a powerful streamlined layer for traffic management tailored to modern health care workloads with a robust lease spine topology. We deployed CloudVision as a service alongside the Arista ABB framework for cloud-based automation and deep visibility.

And by integrating Arista's segmentation service MSS, the customer can now dynamically automate the entire system. In the hospitality sector, and an award-winning regional resort and casino selected Arista to modernize its expanding operations. realizing their legacy network was a bottleneck for innovation, they architected a truly unified standards-based architecture across their data center and campus environments to support new guest experiences and rapidly scale their services.

Arista's routing and switching platforms alongside campus access switches are delivering quality and reliability key to performing in mission-critical applications like their demanding casino gaming floor network. They utilize CloudVision and ABD to automate device provisioning and gain the deep real-time visibility required to optimize network performance. In all 3 of these examples Arista's differentiated EOS provided unmatched quality and reliability and integrated seamlessly with their overarching security ecosystem partners. Additionally, our TAC delivered the flawless experience and peace of mind to derisk these modern enterprise migrations to Arista.

2026 has really been an exciting year, building momentum across our entire enterprise business around the world in data center, campus and AI build-outs. Thank you, .

Thank you, Todd. Wow, that momentum is indeed unprecedented I haven't experienced anything like this until you arrived. We are pleased with Avitas accelerated net working progress across all our sectors. Our commitment to fulfilling this accelerated demand in the second half of 2026 is really playing out well with our improved execution in supply chain, partnering closely with our vendors.

I want to give actual kudos to you and to your entire manufacturing team led by Urena for the tireless work in progress despite the wide head industry-wide supply chain constraints and shortages. With this backdrop, we are now increasing our annual guidance for the fourth time in 2026 to $13.3 billion, which represents a 48% annual growth. At Arista, we find ourselves in a position to address this ever-increasing total accessible market, not just available market, which now stands at north of $200 billion in 2030, therefore, representing a multiyear growth opportunity for us.

Our first look at 2027 guide range puts us in the 38% to 40% range for growth annually to approximately $18.5 billion. Within this envelope, we expect our AI fabrics target to be the fastest growing segment and to double to approximately $7 billion, while our cognitive campus represents a healthy growth of 60%, much faster than the market to approximately $2 billion in 2027.

We do have an exciting times as we harness the power of cloud and AI revolution. It has certainly surpassed my expectations as we exceeded our original $10 billion goal this year to enter revenue dollars in the teens for both 2026 and 2027. We do so in the typical Arista way, bringing our unique combination of innovation, quality, profitability, efficiency, and 0 debt, making our financials very pristine.

Our results would not be possible without the cohesive Arista leadership and team, our elite customers and partners and, of course, our support of shareholders. And with that, over to you, Chantelle, to shed more light on our impressive financials.

Thank you, Jayshree. This quarter, we delivered record high revenue growth since our IPO at 58.5%, partnered with robust operating margin above 49%. At the same time, we invested ahead of demand in R&D, inventory and supply commitments to support the AI opportunity in front of us. Congratulations to the Arista team for being named to the S&P 100 in September, a great achievement within a short time frame. Let's dive into the financial details.

To start off, core revenues in Q3 were approximately $3.66 billion, up 58.5% year-over-year and above our guidance of $3.3 billion. This significant growth was driven by our continued strength in both AI and enterprise customers. International revenues for the quarter came in at $682.5 million or 18.6% of total revenue, down from 23% last quarter. This quarter-over-quarter change was primarily influenced by a shift in the geographic mix of sales to our large global customers.

Year-over-year double-digit growth was achieved in all 3 geographic segments. The overall gross margin in Q3 was 64%, down from 65.2% in the prior year with supply chain efficiency working to partially offset product cost inflation and up from 63.4% in the prior quarter, driven by end customer mix. Operating expense for the quarter were $545.3 million or 14.9% of revenue, up from the last quarter of $411 million. Our R&D spending came in at $408.5 million or 11.2% of revenue, up from the last quarter at $278.1 million.

Arista continues to demonstrate its commitment and focus on network innovation with additional investment in liquid cooling, high vatic switching and leading AI software. Sales and marketing expense was $110.9 million or 3% of revenue, down slightly from 3.6% of revenue last quarter, representative of the highly efficient Arista go-to-market methodology. Our G&A costs came in at $25.9 million or 0.7% of revenue, up slightly from $23.1 million last quarter as we continue to focus on our critical corporate systems and processes.

Our operating income for the quarter was $1.8 billion or 49.1% of revenue, demonstrating our ability to invest in innovation while expanding profitability. Other income expense for the quarter was a favorable $138.6 million, and our effective tax rate was 20.9%. Overall, this resulted in net income for the quarter of $1.5 billion or 41.9% of revenue. Our diluted share number was 1.278 billion shares, resulting in a diluted earnings per share for the quarter of $1.20, up significantly with a growth of 55.8% from $0.77 in the prior year period.

Now turning to the balance sheet. Cash, cash equivalents and marketable securities ended the quarter at approximately $14.4 billion, up from $13.3 billion at the end. Of the $1.5 billion stock repurchase program approved in May of 2025, $817.9 million remain available for repurchase in future quarters. The actual timing and amount of future repurchases will be dependent on market and business conditions, stock price and other factors.

Now turning to operating cash performance for the third quarter. We generated approximately $1.2 billion of cash from operations. This was driven by a robust earnings performance, coupled with an intentional inventory build to meet our growing customer demand. DSOs came in at 59 days, down from 68 days in Q2 due to the timing of customer shipments and invoicing. Our inventory turns dropped slightly from 1.7% in Q2 to 1.6% for the quarter. We ended the quarter with $3.2 billion in inventory, up from $2.5 billion last quarter.

Inventory level fluctuations are expected to continue as we work through the balancing of components timing and availability. This could result in quarters of elevated inventory balances affecting the timing of cash flow from operations ahead of customer deployments. Our purchase commitments at the end of the quarter were $11.4 billion, up from $9.7 billion at the end of Q2. As mentioned in prior quarters, this expected activity mostly represents purchases for chips related to new products and AI deployments.

Our total deferred revenue balance was approximately $6.8 billion, down from $6.9 billion in the prior quarter. The majority of the deferred revenue balance is product related. Our product deferred revenue decreased $86 million sequentially versus last quarter. We remain in a period of ramping our new products, winning new customers and expanding new use cases, including AI. These trends have resulted in increased customer-specific acceptance clauses and an increase in the volatility of our product deferred revenue balances.

As mentioned in prior quarters, the deferred balance can move significantly on a quarterly basis, independent of underlying business drivers. Accounts payable days were 48 days, down from 57 days in Q2, reflecting the timing of inventory receipts and payments. Capital expenditures for the quarter were $100.7 million. Our construction work to build expanded facilities in Santa Clara remains on track, and we expect construction to be completed in the coming months.

As we look ahead, the momentum is strong. We are grateful to our customers and proud of our team's continuous ability to rise to meet the demands of the networking industry. For the fourth quarter, we are forecasting a range of revenue between $3.9 billion and $4 billion. This positions fiscal year 2026 revenue just over $13.3 billion at the midpoint. Our fourth quarter gross margin outlook is 63% to 64% and operating margin is between 48% and 49%. Diluted EPS is forecasted to be between $1.26 and $1.30 with approximately 1.28 billion diluted shares and the effective tax rate is expected to be approximately 21%.

Looking further ahead to 2027, the momentum continues. For fiscal year 2027, the revenue growth outlook is between 38% and 40%, equating to approximately $18.5 billion the midpoint. Gross margin continues to be in the range of 62% to 64% and an operating margin of approximately 49%. Our effective tax rate is expected to be approximately 21%. In closing, there is a lot to be excited about here at Arista. We will continue to be focused on our innovation, execution and delighting customers in the Arista way. Now back to you, Rudy, for Q&A.

Thank you, Chantelle. Shane. We will now move to the Q&A portion of the Arista earnings call. To allow for greater participation, I'd like to request that everyone please limit themselves to 1 question. [Operator Instructions] Regina, please take it away. .

[Operator Instructions] Our first question comes from the line of Michael Ng with Goldman Sachs.

I wanted to ask about your comment around the greater than 10 gigawatts of deployments across 10 plus compute accelerators for next year. Could you just talk a little bit about whether that is an industry number or an Arista specific number in terms of those deployments? And how does the diversification of compute, potentially create more opportunities for Arista networking relative to just having a handful of compute suppliers.

Yes. Thanks, Michael. As you know, I think much of AI, even in our world, started initially being compute-centric, and we're seeing that change to network-centric. And so as part of the accelerated networking strategy, we are supporting 3 types of AI fabrics, scale up, scale out and scale across. So our guess is by the end of '27, we will deploy largely in '27 is where the exponential ramp happened across or greater than 10 gigawatts. Now -- some of that -- much of that gigawatt may be new, but remember, in scale across, we can also have existing gigawatts being deployed.

So we're talking about new distributed 10 gigawatts, but they may already be multiple gigawatts deployed across. So the rationale here is -- while we are new to scale up, we are touching a variety of XPUs and scale out and scale across, across the rack and across data centers. And we already know with our scale across, we are touching multiple XPUs, 4 or 5 of them. With the advent of scale up, we will add another 5 in 2027.

Our next question will come from the line of Meta Marshall with Morgan Stanley. .

Congrats on the quarter. I guess just Jayshree, if you could give an update just on how you see that mix of scale across and scale out and scale up just as a mix of your business, clearly, scale up, nothing today. I think last quarter, you had said you expected 1/3 of the demand this year to be from scale across just as you've continued to increase guidance? And as you look into '27, just what do you see those mixes being?

Yes. I think in '27, Meta, thank you for the kind wishes. We've been working hard for this day. The scale-up will still be in early trials. So I don't think there's a material number associated with scale up in '27. I do think it could contribute in '28. So then that -- if scale-up is virtually 0, then we're basically left with most of the use case being scale out and scale across. And as you've heard us say in the past, scale across, we think, will be at least 1/3, we'll probably go higher in '27. And so the split this year is roughly 70-30. The split next year may be -- I can't venture to guess, but I think the 70% may come down and the 30% would go up when it comes to scale across because it's a very strong use case for us.

Arista is highly differentiated with our 7800 scale across platform. And unsurprisingly, the word scale means a lot to us there and our customers, scale for security, scale for performance, scale for reliability and there's just no room for error when you're connecting million of XPUs. So we feel very comfortable that these are our 2 strongest use cases. I also think it will fuel -- I mean, a lot of this is back in AI fabric. We will come back to revisit the question of front end as well as we move to more inference and the line between back and front becomes thinner.

Our next question will come from the line of Ben Reitzes with Melius Research.

Jayshree, a pretty good quarter and guide there. So I just want you've previously referred to potentially 2 10%-plus customers into the fourth quarter. Do you mind talking about whether they're landing in that range. And what the use cases are for? And if you're excited about those customers still and into '27?

Yes, yes, yes. So I guess diversity is the name of the game and the team today, right, Chantelle? We have diverse accelerators. We have diverse models. We want to have diverse 10% customers, too. So as we said before, our dearest ones are M&M, we fully expect our top prior 10% customers to continue to be with us in 2016, and we hope beyond and we expect to add at least 1, maybe 2. And a lot of that depends on whether Todd and Nehemia can ship enough product. So we'll let them decide and we'll give them all the way into December 31st.

We'll take every day. .

So we're feeling very good about at least 3 and maybe 4. .

Our next question will come from the line of George Notter with Wolfe Research.

I was just curious about the big sequential jump in R&D. It was really, really significant. I'm just wondering if that included some onetime items. Also, is this the new run rate in R&D going forward? Any perspective there would be great.

Okay. So over to you, Ken, why do you spend so much money this year? .

So much new stock. The opportunity is Simona A, these AI tolerating systems. We are -- our success with the hyperscaler AI companies depends on our ability to partner. Our ability to partner is based on our understanding of each of their unique requirements and constraints. And also, there's a new technology introduction around liquid cooling. This requires a major infrastructure upgrades and technology upgrades on our part. So I think that's what's really driving the expansion spending there.

Sorry, George. And just in your comment is the new run rate. I'll still put the framework between 9% and 11% as we work through. So some quarters like we've talked about, we'll hit this range as we have specific investments. And so I would still keep it on that into 11% more to come as we guide next year in more detail.

But I noticed the prototype bill was very high this quarter, Ken.

That's right because of the opportunities in the hyperscaler AI space.

Our next question will come from the line of Amit Daryanani with Evercore ISI.

Thanks a and congrats on a really good set of numbers over here. Jayshree, you talked initially about the industry moving towards a more network network-centric architecture. As customers deploy different type of accelerators, does Arista become involved earlier in designing the overall systems rather than connecting them afterwards. And as you have to work with a more distributed disaggregated compute network? Does that change your networking content per deployment?

I know you talked about 10 gigawatts. I'm just sort of wondering is the network intensity start to change as well? And then maybe for Chantelle, as you think about the 38%, 40% guide for '27, which is extremely impressive, can you just touch on your confidence around the supply chain execution to meet this demand? What's in the bag versus what's to needs to be closed?

This is a very good question. I think until now, we've enforced our architecture mostly on scale out and scale across. And a lot of that had to do with distributed power location, moving to regional edge edges a very software defined type of network with the intensity, like I described of package, flows, performance, predictable latency, et cetera. As we start participating with new accelerators we get a greater chance early in the cycle to see the behavior of these exact accelerators. 2 or 3 examples I'd like to highlight is our close work with Cerebrus, our work with Microsoft and Maya. These have been going on in the last couple of years and has allowed us to tune our buffers, tune our software performance and maximize the IL-2, if you will.

The recognition of those scale-up designs are still in the works, but they're already manifesting itself and scale out and scale across. So you wrap a very good point, not only in the actual work we're doing with these accelerators, but the aggregate impact it has on our network design in terms of scale, performance and reliability.

Yes. And then I think to part 2 of your question, Amit, and thank you for the kind words at the beginning. I think -- so I am confident in the guide and I am continent in the supply chain. What makes me confident in the supply chain is internally, coding Yohan and the team doing a fantastic job every day being scrappy to make sure we can do what we need to do to deliver to our customers. And also I have confidence in a lot of great conversations and agreements with some of our key suppliers, and that's why you see our purchase commitments increasing because we have that confidence.

So internally, externally confident. As far as visibility, I think we have 2 quarters of visibility as we always have, and we need into the other 2. But given our preyfungible portfolio, we're pretty clear where to make that bet. So we're pretty excited about next year.

Our next question will come from the line of Tim Long with Barclays. .

Maybe if we could shift a little bit and talk about the campus and branch. A pretty good year this year and guiding it to 60% next year. Could you talk a little bit about kind of what's enabling you to grow so much faster than the industry? And is this something that you see as a multiyear type of dynamic? Obviously, you got strength in enterprise data centers. But curious what else is helping this much higher than industry growth.

Yes. Thanks for the question. In a lot of ways, I think the enterprise app market is coming to us. Arista has always led the way in quality and reliability. And over the past few years, just practically every significant enterprise has shifted gears and really considered their campus networks, their branch now works mission critical with the highest need for reliability. This is only accelerated because of the glass wing and ethos effect where people are really focused deeply not only on providing the highest level of reliability, but being able to do that as a rapidly patch and adjust their infrastructure over time, and the differentiation with EOS and the ability for Arista software to be able to do this with practically no downtime with extremely, extremely high uptime. It's highly differentiated in the market. And I really think that's the core of what's driving market share gains here. .

I think the other thing that makes us an incremental process is that campus refresh cycles are pretty long, believe in customers understand the Arista advantage may take some time to adopt us because of the schedule in which they depreciate and upgrade their year. So I think we can expect this to be a multiyear cycle.

Our next question will come from the line of David Vogt with UBS. .

So maybe, Chantelle, one for you, and I'll wrap 2 together in 1 question. Can you kind of help us understand sort of your purchase commitment dynamic and your deferred revenue dynamic against strong revenue guide that you provided for 2027. So obviously, we recognize that you're confident in the number, but deferred revenue, I understand that it's volatile and it varies quarter-to-quarter. But just help us understand how to think about that metric in the context of a 38% to 40% guide, particularly also with purchase commitments going up a couple of billion dollars sequentially.

Yes. Thank you. Thanks, David. I think there's a few things. I don't know if they correlate directly, but they're all in purpose and designed to serve the customers as we need to, exiting Q4 and into 2027. Purchase commitments from that perspective, some things additionally we added. Now we have memory in there a memory agreement, which has been that. So that's a multiyear agreement that you'll see as the Q comes out. I think on the purchase commitment side, you can probably expect that to go up a little bit more as we exited Q4 as we get ready for this 2027 guide we have.

As far as the deferred revenue, deferred revenue actually had the largest churn in and out and still remained flat and still delivered a 58.5% revenue growth quarter, which I think is a fantastic outcome. So there, you're seeing things exiting getting released and things to get booked back to the deferred balance, which I think is a really healthy sign of the demand that's fueling that 38% -- excuse me, to 40% revenue growth next year. So I think they're all related purchase comes grow to serve that demand in the first day flat to deliver that outcome to the P&L, and we're pretty excited to see how that continues through 2027.

Our next question will come from the line of Simon Leopold with Raymond James.

Appreciate that. I wanted to get 1 quick clarification. You gave us targets for 2027 for campus in AI. Just wanted to check on what the baselines are for 2026. And the question was really on a topic that I think Andy has been vocal about, but your thoughts about the evolution of switching with the inclusion of either CPO or NPL, what does that mean to Arista?

Okay. Just to clarify, the baseline upon 38% to 40% is the '26 guide we gave of 13...

Yes, $13.3 billion. Yes. And within that AI is $3.5 billion and campus is $1.25 billion.

Yes. We're staying with the target numbers because we'll only know actuals after we ship everything end of the year. And to your second question on Optics. Optics is very integral to Arista strategy. Andy Bessen, our Chief Architect, lives and read this. It doesn't mean we build everything, but we actually systematically put it together. We, first of all, strongly believe in copper when you can and optics a few months because when you go beyond 1 or 2-meter radius, the flexibility of pluggable optics and lasers is probably the most widely deployed and accepted.

Andy was a pioneer of OSFP that gave us a very wide density of thermal limits and widely used. And now our new coherent optics LPO models is something that goes long distance without requiring DSP. And then to meet higher front-panel density, we're very excited about extra rent pluggable Optics that can -- that is being supported by over 150 vendors. So we think the world is going to remain in a very majority fashion on pluggable optics.

Having said that, I think there's always room for complementing the pluggables with a strong adoption at higher speeds to what we call near packaged optics or open CPO. We don't want to build proprietary co-package optics and to solve these constraints, Arista is pioneering this open CPO. That instead of sovereign components, we can use socketed optical engines and picaybers to allow these modules to be pretested, et cetera. So we are big fans of these. We think they'll come on to the market in the '28 to '30 time frame. It's not imminent. But meanwhile, long live pluggable optics.

Our next question will come from the line of Joseph Cardoso with JPMorgan. .

Congrats on the results as well. Maybe the question that I wanted to touch on and maybe it kind of dovetails off of a clarification on the last one. When we take a look at the initial full year guide for 2020, particularly as it relates to maybe the non-AI noncampus business. I think growth is being implied to moderate from the strong 2026 levels. I was just wondering if you can kind of touch on the underlying assumptions or factors that may be driving a little bit more moderation here into 2027 and whether that's maybe just tough compares or conservatism in terms of supply, et cetera, just trying to understand directionally what's the drivers of the 2027 forecast that relates to the maybe core business?

Thank you, Joe. Well, listen, when some things are growing 60% and 100%, and then you say the overall growth is 38% to 40%, then obviously, some of the things are not growing as fast, right? We are very comfortable that everything is going to grow double digits, some more, some less. And we're also very comfortable that given a first guide literally over a year before that all sectors are doing well for us. AI, enterprise, specialty cloud providers, front-end networks.

So we started out 2026, wondering with front end to grow -- so it's a cyclical thing. When the back end grows, the front end may go a little slower and the bet slows down the front end, may grow a little faster. So I wouldn't read any conservatism into these numbers. These are widely higher and optimistic than we had once projected. So enjoy them for a moment and hopefully, they'll get better.

Our next question will come from the line of James Fish with Piper Sandler.

Fantastic quarter and guide here to start for '27 ladies. And can pose gentlemen and 2 ladies yes. And Todd, I didn't forget about you, Todd. But look, I appreciate the early outlook, but you guys always talk about 1 to 2 quarters of visibility. You tend to be a very prudent team. And so maybe going back to, I think it was Amit's question, I guess the confidence in providing this durability of this scale, this early and why we're going to see this kind of strength persist why Arista for scale up in 2028.

Well, I'll just go back and thank you for the kind words...

The kind words for ladies and gentlemen. .

That's right to all of us. I think that -- so let's go back and reiterate the confidence level. There was a lot of thought obviously put into a guide that's strong this early. So there's a lot of attention with Ken and Jayshree and myself and team. So we had to get comfortable first, and we're very comfortable with all the things we've done to see what we need to go ahead. And again, the 2 quarters visibility, 2 years of relationship and technical conversations. So somewhere between the second half lands and it's the usual kind of cadence we have. So nothing has changed there. I think from -- and then the second part of your question was about scale up going into 2027, 2028, Jayshree?

Yes. So listen, I think scale-up has been a tough market for us because it doesn't have all the software advantages that we bring, but it absolutely has the hardware skills and all the non-NVIDIA accelerators that Arista is in the best position to connect to. So this movement from stand-alone basic switches to that scale is something that Andy, Alex, you hold book, the entire team has been working on and codeveloping for a couple of years. It's hard work. .

Just as we are staring at InfiniBand and now we can do, of course, it's going to be Ethernet. We're looking forward to a time where we were staring at proprietary UA Link or NVLink and we're going to go, of course, it's going to be ESUN, but these type of migrations to do are multiyear. And so we're very confident not only in our '27 guide, but a promising '28 ahead as well. And the reason we are is because even though we have two quarters of visibility, we have 2 years of work behind us.

Our next question will come from the line of Tal Liani with Bank of America.

Ladies and gentlemen, sorry, I'll start from the beginning. Thank you, I missed the call last time, and you raised the guidance substantially, and now you are doing it again. And on the other hand, I heard Chantelle explanation about deferred revenues, but the sequentials are slowing down. If I look at total Ferd and current deferreds are slowing down. But you are feeling more comfortable with next year and you're guiding well, well above the Street.

So the question is, when you look at orders versus recognizing from deferred because of the availability of components because of releasing kind of deferred revenues because of completion of build-out, et cetera. So what are the drivers for -- like same question about from different angles, what are the drivers for the growth? Is it orders? Or is there some part there of recognition of historical orders? And then is deferred revenue actually losing some of its predicting ability just because I see some decoupling between the deferred revenue trends and revenue growth trends.

Okay. Let me start and then, maybe Chantelle, will you take over? So I think, first you tell -- we missed you last quarter because we don't get this level of detail from anyone else on exactly what are the puts and takes. I just broadly look at you and say, hey, it's great demand. And if you want to dissect demand into how much is fitting into deferred, how much is fitting into our orders, how much is getting shipped into revenue, you're turning demand into a physics problem that I don't have the answer for. Because I don't predict or forecast deferred.

Deferred is a strong function of a new use case or a new product that eventually is not a new use case or a new product. So we had millions of dollars come out of deferred if this use case is satisfied. We had millions of dollars go in as deferred. And generally, that number, if you look at it over the last few quarters or if you look at it over the entire year, it's trending up but deferred is never going to be infinite.

It is going to come out and other new deferred will go in or the product becomes familiar and less new, right? So it's important to just look at this big picture and say, we got demand. We've got demand in AI, in enterprise, in campus, in data centers, and we're just in the best position we've been in a long, long time in my 18-year career. Over to you, Chantelle, you want to.

The only thing I think it was very well said, and I think that's the right perspective to take on this, so we don't get too lost in the means of a quarter-to-quarter basis. We're very confident in the demand in the guide. Burgas a balance sheet account that will reflect whatever happens in the quarter. So that is what it is. The only thing I would add, like I said before, Tal, we did it do last quarter, was that we anticipate the end of this year from a deferred balance to be higher than we ended last year, which shows that the P&L did what the P&L needed to do without deferred. And so if that helps you feel more comfortable with that and that's the only thing I do with.

Our next question will come from the line of Ryan Koontz with Needham & Company.

I wanted to follow up on some of your scale-up commentary and ask about some of the technical design changes a little bit here with obviously, including more optics and including liquid cooling. And how will that change your fulfillment model? What things are you including in your sale versus partner to reference third parties? And maybe you can expand a little bit on your product plans around scale up and how we should think about the product changes?

Yes. Actually, that's a really good question, Ryan. We're still figuring it out ourselves. Because Arista's value in the rack scale is still the switch. But however, we have to design the whole rack and then work with different partners differently on whether they want the whole rack from us or the rest gets shipped through our manufacturing partners, while we basically ascertain the switch.

So each different stocks for different books because we've got 3 different designs going on with the orthogonal, the cable black plan and the cross rack designs, each one a little bit different. Give us a chance in the next few quarters to share with you what's going on with each one. There isn't one answer to your question.

The one last thing I do want to add to that is, but what's very clear is there's a lot of switches simming and water. A lot of it's liquid cool.

Our next question will come from the line of Karl Ackerman with BNP Paribas.

Chantelle or Jayshree, I'd like to ask a question that was similar to peers, but in a slightly different way. In the context of your 2027 revenue outlook, can you speak to whether your revenue outlook is predicated on new permitting or financing of power shell infrastructure to achieve these forecasts? And as you address that, can you speak to whether you require an aggressive drawdown of your deferred revenue balance to achieve your outlook? I think I know the answer, but we love your view.

What do you think our answer is.

Yes. It's so nice to sometimes ask a question ourselves.

I don't think you need to, but I would love clarification.

Okay. .

Yes, we're not -- we don't guide deferred. So I think that was the answer you were expecting to secondhand. I would say from the perspective of the guide next year, -- we are looking at what we know ahead of us, 2 quarters visibility taking a lien on the second half of the next year in the sense of what we've had conversations with some of our largest customers. the run rate we have in Cloud's business in a sense of enterprise and all that comes to other, but we don't guide deferred.

This question was are we counting on data center.

The first part, the second part was are we preparing to draw down deferred to hit the number?

Yes.

So we don't guide deferred, but I would say that we see a very strong demand signal and demand environment back to the momentum theme, but Jayshree, do you want to comment.

Right, exactly. So I think while we don't guide deferred, let me be clear that we do see plenty of new use cases and new products. 2027, like '26 is going to be filled with lots of new products. .

Our next question will come from the line of Jin Marcote with Deutsche Bank.

Congrats on a full set of great numbers. As SU-144 moves towards production in '28, how should we think about gross margin economics relative to your existing switching portfolio. And how much customer commits do you already have behind those programs? .

You're talking about '27 or '28?

It's about gross in for...

Look, since we went public, our long-term gross margin has always been in the 60% to $65. I think we've tightened the rain now to more like 62% to 64%. We don't see any change. .

Our next question will come from the line of Daniel Zhu with Bernstein.

Well, congrats on a great quarter. I just want to ask how concentrated the customer base will scale across. Should we think about this as really being driven by the cloud titans for synchronous training? Or are we also seeing telcos deployments even among smaller customers or for infant use cases?

Yes. No, I think there are both small use cases and colos for scale across, which would be a smaller footprint switching and routing platforms like the 7280, but the concentration of our large customers also is high with our larger customers opting for the very large AI spine across data centers and requiring that kind of 576 port density and terabit scale and multi-gigawatt deployments for securities and performance. So we do see both. But I think the revenue concentration favors the 7800. The location concentration of multiple sites favors the 7280. .

Our next question will come from the line of Sean O'Loughlin with TD Cowen.

Congrats on the fantastic results, ladies and gentleman. To just check in broadly on where we are actually in the front-end cycle. I think we've spent so much time talking about scale out, scale across back-end deployments and the focus on 800 gig and above in those deployments that maybe we collectively have lost track of where we are in the sort of more traditional front-end compute. I'm just wondering if you could comment on that and what you see in terms of market trends on the front-end specifically?

Yes. No, Sean, it's a very good question. I think there are -- it's like a sine wave. When everybody is focused on the back end, then there's -- in those customers, they're thinking less about the front end. And then sometimes when they're focusing a lot on the front end, they're not worrying as much about the back. If you look at it over a period of time, like 6 quarters to 2 years, you can capture both -- but in a given year, we had one 10% customer, for example, put a lot of thought into the multi-hundred-gig refresh of their front end before enhancing their back end. And so that particular year, the front end is very high, but the back end was low. The following year may be the reverse.

So if you tend to look at it over multiple quarters and years they even out. But if you go to look at it in a concentrated period of time, you'll usually see more of 1 than the other. Right now, in general, we're seeing more back end and AI fabrics, and I think the front end will catch up later.

Our next question will come from the line of Antoine Chkaiban with New Street Research.

Congratulations on a very strong set of results. Ken, maybe 1 for you, I want to ask about AVA with all the recent high-profile infrastructure security breaches that we've been hearing about. It looks like that technology can address a very large opportunity. So how should we think about sizing it? How do you plan to monetize AVA? And is that going to fall into products? Or could you drive actually a meaningful acceleration in your services revenue?

We are at early days in understanding all of that. We have just turned AVA on as an alpha feature for customer trial within our CloudVision service. And we are currently working on pricing models. I don't think I have any forecast or data to share with you at this time on that.

But I think it's very promising, Antoine, because back again to Ken's point that he repeatedly makes with me is the architecture of the U.S. is so sound that adding AVO CloudVision our capability to look at deeper details and get more analysis starts with the foundation, right? So we feel very privileged that we can sit here and make a tell, well, oh my god, our vulnerabilities doubled from 30 to 67 and we fix them. And therefore, we can go apply AVA. Everybody else is dealing with a game of wakamol where they've got thousands of vulnerabilities and no AVA can possibly keep track of it. So I think we feel in a very good position to monetize AVA in the next few years. .

Our next question will come from the line of Ben Bollin with Cleveland Research.

Jayshree and Todd, I suppose, I'm interested in your thoughts on where lead times are across the portfolio if we kind of carve it up into enterprise-centric and hyperscale centric? Just what those look like today? And I was hoping, Todd could talk maybe a little bit more big picture about the go-to-market effort, the execution within enterprise share capture and how that's building and where that goes from here?

Yes, on the lead times, and it goes both for the component lead times on the finished good lead times. In the enterprise side of our business, we tend to have shorter lead times, somewhat shorter. And that's driven by the fact that those switching model is in the absolute cutting edge. They're not leading brand-new technologies requiring the highest process, silicon, et cetera. And we're able to -- they also tend to be at a lower price point, we're able to hold a little bit more buffered inventory there. So we tend to have lower component lead times there and lower lead times to our customers on the AI side, on the ultra advanced hyperscale data center lead times tend to be a little bit longer.

As far as the build-out on the go-to-market side, we were really -- we have been just really pleased with the momentum we've seen this year and the herd that's being built into the whole go-to-market on the kind of thought leadership side and the awareness side, we saw great momentum on the -- from webinars and from events. In fact, we have our largest customer event coming up in December, which we're very excited about. And on the sales execution side, it's been just phenomenal efficiency from that team, and we're looking forward to continuing to build out next year.

I just want to add, Todd, also I see that you and Chris Schmidt, Postea, you really heightened the investment not only in the United States, but with key verticals and international as well. So I think all of the go-to-market investments we've been making over the last year and in fact, the last 3 years is really paying off. .

Absolutely.

Regina, we have time for one last question.

Our final question will come from the line of Mehdi Hosseini with Susquehanna.

I have 2 quick follow-ups. Going back to your revenue guide for '27 is $8.5 billion. Should we assume that all the sell have been planned for? And then the second question, if you could elaborate on the mix between cloud and enterprise. I just want to get a better understanding how enterprises are investing as it relates to hyperscalers.

Sorry, you asked is all the silicon planned for already in the $18.5 billion. .

Should we -- since you are providing additional assessment on 2027 revenue target, should we assume that you have already planned with your suppliers and selling in secure for both compute and memory. And there are some that argue that ties is going to get worse in '27. I just want to make sure that there is no downside to this target as it relates to inventory management.

Understand, understand. Yes. We work very, very closely. We're sort of proud of our strategic partnerships, and we've been investing heavily in long-term strategic agreements in order to secure supply, not just in silicon, but PCB capacity memory, which Chantelle mentioned earlier. So we're incredibly -- we have very high confidence in the ability to deliver supply to the forecast. We -- of course, we would not want to place everything to 5 quarters lead time for all of next year. So not every order is placed.

This concludes Arista Networks Third Quarter 2026 Earnings Call. We have posted presentations that provide additional information on our results, which you can access on the Investors section of our website. Thank you for joining us today and for your interest in ourself.

Thank you for joining, ladies and gentlemen. This concludes today's call, and you may now disconnect.

Everyone, welcome to Day 3 and the final session of Citi Global TMT Conference. We have definitely saved the best for the last. My name is Atif Malik. I cover U.S. semiconductors and networking equipment names. It's my pleasure to welcome Chantelle Breithaupt, Chief Financial Officer; as well as Tyson Lamoreaux, Senior Vice President, Cloud and AI Networking at Arista. Welcome, guys.

Thanks so much. Thanks for having us.

Thanks.

I'll kick it off with my questions first. If you have a question, save it towards the end, we'll send the mic and you ask your question. Chantelle, deferred revenue has been a hot topic this year on Arista. Arista consistently achieves strong revenue growth and has guided to 40% growth this year and yet the complexities of AI use cases have resulted in strong growth in Arista's product deferred revenue. What is the right way for investors to think about Arista's growth? Is it the growth in the revenues plus the change in deferred revenues?

Yes. I think it's a great question. We're super excited to, in the last earnings call, raised our revenue guidance to be 40% growth, $12.6 billion. So we're very excited to be able to deliver that kind of guidance. And so if we think about it, deferred revenue is a topic. I think that if we just level set what deferred revenue is, its if you're talking about the product deferred revenue, that means equipment that's been shipped, invoiced and cash collected, but we have acceptance criteria that keeps us kind of skin in the game with the customer to get to the kind of net results they want to get to. And if you think about what goes into here, it used to be the cloud, if you go back a couple of years, the cloud deployments were put in there, and now AI has basically put that on steroids from a complexity to your point.

And so from a -- from how do you interpret it perspective, I think if you look at Arista, there's a few things I would keep my eye on. I would keep my eye on the P&L growth, what's happening in deferred revenue, but I wouldn't do a quarter-over-quarter kind of thing. I would do a trend over 4 quarters, maybe 6 quarters because things will come in and out generally because it's an acceptance-based criteria. I would look at the purchase commitments and maybe what's sitting on the RPO table. And all four of those things kind of give you a picture of what's happening and what's to come. I think that from the perspective of deferred revenue as well. And sometimes that people don't understand that some of these deployments can take 18 months to 24 months until we hit the acceptance criteria. So it's important to understand the timing of how long this could be and when we would realize it from a P&L perspective.

Great. And Chantelle, just for perspective, how far are we into this current cycle, the deferred revenue? And how does it compare to what Arista experienced in prior cycles?

Yes. So even though we're now going to be part of the S&P 100, we're only about 12 years old as a public company, right? And so we've had, I would say, two cycles, the cloud cycle and the AI cycle. And so what you're referring to Atif, is during the cloud cycle, which is kind of the 2019, 2020, '21, you saw deferred revenue raised because we had this deferred construct because we had the use case of cloud, 400-gig and then coming into 800-gig. And then we kind of went through a little bit of cloud and then AI took off.

So this AI cycle is the second one. The cloud one was about 3 years. We're in, I would say, going into year 2.5 to 3 on AI proper from a materiality perspective. But I think there's many years to come on this cycle. And so we'll have to see because we're talking about scale up, scale out, scale across, training, inference, front-end, back-end. We don't see AI going away anytime soon. So this cycle could be longer.

All right. With that topic out of the way, the next big topic has been the supply environment. Supply obviously remains challenging. And on your last results, you came out a lot strongly on supply. Where are you seeing the most pressure in the supply chain?

Yes. So we started the year, and we'll -- I'm very transparent. Q1 was not our favorite call because we did have to talk about the supply chain environment. I think that's what you're referring to. But we wanted to be honest and transparent. A lot of this pressure is coming from right at the top of the fab capacity. And I think anyone in the industry should be talking about there is tightness no matter where you sit in that hierarchy. But as we work through to the Q2 call coming into August, we did find some vendor arrangements with fab capacity, memory. So those things, I think we've sorted through '26 and '27.

But you have whack-a-mole on some of the other component parts, PCBs, capacitors, et cetera. So there's things that are more peripheral short term, and then there's structural things like fab capacity. But we feel very well positioned. When we talk about purchase commitments now, that's a year lead time for chips going into Q3 next year. So we're already talking that $9.6 billion at the Q2 end purchase commitments is already going into second half next year. So well positioned, but we -- I don't think anyone is out of the woods when it comes to the full supply chain for networking data centers generally.

And can you remind us any purchase commitments you made to secure the supply?

So we ended -- so we've grown -- if you look like 3 quarters ago, our first quarter was about $3.6 billion, and now we're at $9.6 billion at the end of Q2, so over 3 quarters, basically tripling it. And that's leaning into demand we're seeing. So you should see it as a demand. It's getting some of these memory things sorted. And then there are some things that are a little bit longer than 12 months. But from that perspective, we feel very good that the supply chain team learned a lot during COVID, learned a lot during the beginning of AI, got the contract manufacturing components sorted. So I think it's a demand signal at this point, and we feel very confident about that.

Awesome. Tyson, a lot has been said about the differences between AI traffic and AI networks versus classical cloud computing network and Arista has developed its Etherlink portfolio to address the opportunity. What commonalities are there between Arista's Classic Cloud Solutions and hardware and software versus the AI Solutions?

Yes. I think Chantelle and I were talking about this a little bit earlier, too. And Arista's like heritage and foundation, we believe, really put us in a very well-suited position for the AI era. In a way, the company was born and bread to be prepared for the AI era. And so there are clear distinctions between cloud, traffic, architectures, hierarchies over subscription, interface speed, upgrade cycles, refreshes and how the compute is interconnected. AI is much more demanding. The traffic profiles are significant. They're very highly coordinated. The reliability is essential at every level of the piece of the infrastructure because you don't have the ability, at least with current generation AI technology to provide ways of working around failures as easily as you do in cloud-type primitives. So the demands are just very, very high here.

And I think the commonality for us from the kind of where the company forged its foundation was rooted in reliability, security, performance and scalability. All of those dimensions are more critical for AI than they were even in cloud. And I would highlight, two, in particular, that kind of root around our heritage in hardware development, the ability to deal with latest generation -- intercept latest generation technology, overcome very hard electrical engineering problems, signal integrity problems, power integrity issues, things that are exacerbated as you move up into faster link speeds as we're now kind of transitioning to the 1.6T generation. These are very difficult challenges. You're emitting a lot of heat because you're consuming so much power. So your ability to cool that and be power-efficient is super critical. Something Arista has really kind of built its heritage again in hardware engineering around. So that lends itself very well for our Etherlink platform in AI fabrics.

And then the software is another piece on the reliability side and the security side that's essential. One of the things that's come to front of mind for a lot of people is -- in the last year really is Mythos and Glasswing and the notion of AI-driven attack vectors and an ever-increasing rate of security vulnerability discovery, fixes, patching and this cycle that needs to basically run continuously now to keep your network secure. One of the benefits of our software is that it was built on a foundation of always staying up so you can patch the software, deploy it and you can automate the entire workflow seamlessly so that your data plane is never interrupted. The network stays up, traffic continues to transmit across the network. That gives us a real relative advantage against competitors as well as open NOS and other type of solutions. So we feel very good about that foundation that we've been able to carry forward into the AI era and get leverage out of it.

And then that reliability aspect. I mean if you're talking about reliability that is a full point better than the next best in the industry, that kind of 1% improved availability translates in a very significant way when you start talking about amortizing availability across all of your accelerators, which are the lifeblood of AI, right? This is the biggest expense. This is what you're spending the most money on. You don't want that capital sitting around idle, you want putting to work, you want your high utilization. So the speeds and feeds, cutting-edge technology, reliability and security story come together very, very well. So it served us well in cloud. I think it's serving us even better in AI.

Great. Historically speaking, you guys had concentration at 2 hyperscalers, and you've done a very nice job in diversification at the hyperscalers with potentially 3 or 4 this year, depending on how things shape. But the hyperscaler concentration is improving. On the non-hyperscaler side, the neoscalers, and enterprise, can you talk about your adoption cycle over there?

Yes. We're very excited about these other non-hyperscaler environments. So we talked about -- we do have 2, 10% customers that you're referring to. We do anticipate a third and potentially a fourth. So that diversification continues. From a neocloud perspective, the one thing back to Tyson's commentary, the neoclouds are looking for a few things. What makes them competitively advantaged is their token cost optimization. And so they come to us to say, you have great experience both on AI front-end and back-end and cloud. Can you help us get to token optimization as quickly as possible with your vast portfolio? And so all the different architecture designs that help them get to their token cost optimization. If it's a fair fight in the sense of it's a best-of-breed conversation and it doesn't come down to commercial arrangements, taking the customer in a different avenue, we have a very good chance of winning.

Even some of the neocloud customers who have gone with a competitor perhaps for different reasons, have come to us perhaps for their second installation because they realize the best-of-breed will get them to those token cost economics, which is how they stay in business. So we're very excited in both local and international growth from that perspective.

And enterprise, enterprise, I think, is just getting started. We have about 20%, 22% market share in data center. So even if we just continue doing classic data center, there's market share to go gain. But why else would enterprise want to accelerate their next refresh for us. Back to the Mythos environment, if you think about where some of these enterprise players are, they are very nervous about if they're currently with many different operating systems, how they're going to get on this patching treadmill when it comes to making sure they're secure. We've had customers come to us that are new logos ahead of their refresh to say, we're very interested in your EOS because we only want to patch once and we want to make sure that it's done properly because we have the lowest CVEs in the industry by a magnitude of 30x to 1x.

And then the other reason the enterprise is coming to us is just total cost of ownership. With one EOS with CloudVision, they can get rid of the 50 to 60 to 70 people, perhaps 200 they employ, just always be constantly updating, taking the system down, repatching. So from a TCO perspective, enterprise is also very excited. So market share and TCO is a conversation there. And then you go to campus of the enterprise, right? Campus, we have 5% market share going from $800 million in '25 to $1.25 billion in '26. That growth rate is definitely larger than the market growth rate. So that's a share gain story. And that will be a long, slow rinse, repeat that we're very excited. And we win campus-first deals, which is a great validation of our portfolio and our brand recognition. So there's land and expand going back to the data center the other way. So there's lots to be excited about, I think, in those two categories.

Security seems to be hitting a nice flywheel for you guys. Scale across AI applications have emerged rapidly and are expected to be approximately 1/3 of your AI mix. What is driving the growth in scale across? And what could shift the scale across mix higher?

Do you want to start?

Sure. Yes. I mean I think I'll start probably with the back end of that, like what could drive it higher. Constraints are driving a lot of this in general, and there's some architectural choices and there's some desire to distribute data centers either because you can't get the power and data center space in a single facility that you'd like or you want some resiliency kind of built into your infrastructure so you choose to distribute. But another big driver here is actually coming around not just driven by constraint, but enforce constraints, regulatory regime change and like top-down government initiatives.

So I'd highlight like a good use case that really exemplifies it is, if you look at South Korea, the government there is actually driving by policy, distributed generation and local consumption of power. And so by its very nature, what's going to happen to the data center infrastructure inside of South Korea is it's not going to concentrate into a small set of locations or cities where all the capacity is kind of all your eggs are in one basket. It's actually going to distribute around the country. And naturally, that is going to drive much more demand for a scale across solution because your single largest facility is going to be capped effectively based on the local power available to it. And so as things federate, you naturally have to interconnect them and interconnect those clusters. That is something that can shift and change and shape the scale across TAM quite a lot. I think I'll let Chantelle talk more broadly about the TAM and how we think about it.

Yes, I'd be happy to. So we are revisiting our TAM generally. Like at the last Analyst Day in October '25, we gave you a $105 billion TAM. A lot has changed even since less than 1 year ago. So we'll be revisiting scale up, scale across and hopefully come back to you later this year with a revised TAM. So we see that expanding for all the reasons Tyson listed.

But also to provide a framework perhaps to help the audience just how this scale across kind of gets us to Arista being a good choice. We're very well positioned. The customers, we feel are looking for a combination of great software operating system, hardware and AI experience because this isn't just a DCI. This is a DCI with a much more complicated structure and high large clusters, right? So if you have AI experience, software and hardware, I think that's what wins in scale across. And we don't feel our competitors have all three. Some might have DCI, some might have AI clusters, but we don't see any of them that have all three. And that's why we feel incredibly well positioned for scale across. It's a wait to see on the TAM, but if the TAM increases, we're very excited about that.

Great. And then on the scale up, the market has been waiting for Ethernet standards, but a consensus is emerging that scale-up will be a huge opportunity. Broadcom talks about Ethernet being a leading candidate. How do you see the mix between scale-out, scale across and scale up evolving?

Well, I can talk about the mix and then maybe we could talk a little bit about scale-up or perhaps your questions will leave us there. So a lot of this depends on what timing we're talking about. So from scale up, we have 0 in our guidance and 0 revenue for Arista for scale up in '26. We feel that we'll start to get some kind of maybe trials and pilots similar to our InfiniBand Ethernet conversation later next year because the ecosystem has to come together. This is -- Ethernet scale-up is going to take some ecosystem parts coming together because it's a bit more complicated. So we're talking '28 is when we get the revenue there. So that's why I say the percentage of will depend on the timing.

Scale across, I imagine, will happen a little sooner because we'll see that '26, '27 and '28. So both will have great growth trajectories, but the timing of it, it makes it difficult to answer your relative perspective. We're hoping all three are running very well for us when we get to '28 when all three are online, let's say. But we'll have to see the timing of all those three, how they show up.

And then Tyson, can you touch on the XPO road map? And when do you guys intercept that in terms of revenues? And how does that fit in this whole kind of NPO, CPO road map?

Yes, yes. We feel very good about the like road map in general for our products and the base building blocks that we have in place for advancing our product portfolio kind of generation over generation and to intercept NPO and CPO. I mean we are customer-driven in terms of our product road map. And so if customers want a CPO switch, they want an NPO switch, they have certain requirements that need to be fit. We're going to go build that switch for them.

I think you've got some alignment right now with XPO and kind of the scale-up timing. There's some coincidence to that, like -- but they're also not just purely time coincidental. There is form factor and bandwidth density that comes with scale up. And so as the Ethernet standards around ESUN are ratified, you get chip production, chip production leads to the ability to build a system. You're talking about very dense systems here. We're going to build scale-up solutions to kind of focus on customers who would like either co-packaged copper for the lowest possible cost, but those are going to be constrained in terms of their reach because you've got a bandwidth kind of over distance problem. The longer your link is the less bandwidth you can attain over it. That gives rise very nicely to an NPO solution, which is what our XPO architecture is focused on. The ecosystem is coming together very well. The module makers are building all kinds of products, and they're going to come together very well in that time frame. It's a product that we think it fits very nicely in our portfolio through optionality, serviceability in the field things that our customers are telling us they want.

It's also going to help them start to get them that multi-rack high-density scaling that they require that copper isn't going to reach into. So we see this as a nice kind of 2, 3-generation solution that lands in between kind of copper running out of steam and when CPO can really be built at scale. But we expect some early adoption on CPO for sure. We're ready to build as soon as customers are telling us that they want it and need it. I think you'll follow -- you'll find a pretty common adoption there, like early adopters really drive the front of it. There's a whole ecosystem that has to be built out. It's a completely different manufacturing technology and architecture. The supply chain has to come together for it. Yields are going to be very challenging in it very early on. So there's a lot of customers who are being pretty pragmatic about it in terms of their expectations of when they can intercept and what value it's going to create and when and when the costs are going to stabilize and the volumes are going to increase.

So we like the road map we have right now, which is just continue copper as long as we can, bring NPO and XPO into the fray, build out a lot of the modularity in that generation to be able to then feed into CPO and then CPO coming on. So I think XPO early deployments second half next year, really ramping in '28 and probably 12 months behind that is where we start to see some of that CPO ramp occur.

And do you guys have a view in terms of the mix of ESUN versus UALink, like where is this kind of market going?

Well, we see -- again, we're still learning about the TAM in the market because it's a fairly new thing. But preliminary views, I would say, just from a framework perspective, we see this starting off as 3 segments within scale-up. We see the proprietary, which you could put NVLink and UALink. We see probably some sort of commodity white box play for the lower value add needed. And then we see value-add Ethernet, which is where we will play. And so two things to think about. One is, if you have an overall TAM, how much does the Ethernet part start at? And is there eventually a journey similar to proprietary to open standard Ethernet, you could say NVLink or UALink to Ethernet. Is that a journey where that starts to shift over time? And that's how we're starting the framework of this.

Great. Let me pause there and see if there are any questions in the audience. If you have a question, please raise your hand.

You touched on optical a bit in your discussion of XPO, NPO, CPO. Is vertical integration something that you're considering given the rising importance of optical networking?

Well, we are super -- we have deep conviction, I should say, and super engaged on making sure that ecosystem comes together. I think we're going to be pretty prudent about vertical integration where we feel like we can really add value. I don't think it's really something that we want to do to go spend time, energy, effort, CapEx, R&D resources, de-frame kind of our focus on building products just to be another commodity provider. So in a world where we're talking about like XPO and XPO modules, we think that's a really rich ecosystem. And I don't think we really see a need.

But if a customer comes to us and say, they really think that there's value in being able to come to a single source. They believe that they are going to gain significant benefit out of offloading a bunch of tests, qualification, verification work to us rather than taking it on themselves. They want to kind of simplify their supply chain so they can focus elsewhere. We're going to be open to those conversations. I mean that will factor into like what do we stick on the road map, when, where and why. Unsurprisingly, like we built up a very competent team in the optical domain because it's so essential. Connectivity and connectors are so essential, as we continue to step through the greater speeds and into next-gen platforms. So we feel well positioned from like an engineering product perspective. There's something to build there. There's a there there, like we can go do it, but nothing hard committed at this point. I think it's something we'll continue to discuss a lot internally. Keep listening to customers, and I think you'll learn about if we choose to do something like when we're ready to launch it because we don't tend to preannounce anything.

Can you talk to -- I know it's early, but like scale up Ethernet, does the -- your value add, obviously, is software. It's a big part of the pitch. Does the software requirements, do they go up? Do they change? Maybe just talk to that. Is the ecosystem different? What value can you bring to it? Maybe talk to that a bit.

Yes. I think if you went back in time, maybe 12 months, there was a lot of like momentum around the notion that scale up is really just a big fat dumb pipe, and therefore, there's not really much value to add. This is going to be a great white box play. I think there are white box companies out there who have definitely said we think this is a great opportunity for us. I think the reality is everyone is kind of recognizing like reliability and security are just as essential in scale-up as they are anywhere else.

Like if you're losing GPU workload time or accelerator workload time because your network is down, your scale-up network is unreliable. You don't have the telemetry, you need to debug issues, even after the silicon is shipped and the ESUN spec is ratified and you've got a purpose-built product in place, that's going to be kind of a deal breaker for customers. So I do think EOS and our software advantage is meaningful there. I think the feature set is definitely smaller. You're seeing kind of a shrinkage in terms of like breadth of capabilities. And so the question is going to become like how much do the features and differentiation matter? It's a breadth versus depth kind of question.

But I think I'm gaining personal kind of deeper conviction every day that the security story is going to be really credible here for us and much better than a lot of our competitors. And if you look at the open-NOS ecosystem, you're subjected to long delays, self-discovery on vulnerability, fixes, reviews, reporting regimes that are dictated kind of by a governance model. There's no test infrastructure readily available to everyone. You've got to do it yourself. So these are real challenges for anyone who wants to go down the white box route no matter where they're going to deploy it. You've got to be really committed if you want to do that. If you think about the total kind of expansion of the TAM and scale up with Ethernet specifically over time, it's going to be a variety of different types of customers. It's not just the hyperscalers. It's not just the most sophisticated types of customers. I think we're going to see that represent a lot of the customers we're working with now. And I think a lot of the things that are leading to wins for us now will lead us to wins in that domain as well.

Chantelle, last year, I said you're making Ita proud. This year, I'm going to say you're making Ita more than proud because in the last 2 years since you joined the company, Arista's operating margins have expanded impressively by 100 basis points. How do you think about the balance between investing in the business, innovation in kind of high-cost commoditized environment? Are there areas that you're targeting for more operational efficiencies?

Yes. I think if you look at our -- so thank you. Let me start with thank you. I hope I've made Ita proud with the transition. I think that from a perspective of -- if you think about our guidance, so we're guiding basically a 62% to 64% gross margin and 48% range. That's almost a Rule of 90. So I don't know if we're looking for more operational gains. However, there is a lot of operational leverage, which will come through depending on the mix of product. When you think about our 40% revenue growth this year, we do not need to scale the same rate in the sense of our operating cost. So there is expansion to your point. And so I think we'll continue to see where we grow and how we grow and how much more operational efficiency we can get.

But we do get a lot of leverage from the area Tyson has specifically with the kind of cloud titan space, neoclouds, et cetera. So we'll have to wait and see. But even if I keep the same ratios, -- we'd like to be obviously innovation forward. That's our goal. So if you think about R&D is usually 8% to 10% of revenue. If we grow 40%, that gives Ken a whole lot more just pure dollars to go play with, right? And so we feel comfortable that same sort of range, sales and marketing, 5% to 7%, G&A is an amazingly 1% or less because we only have one P&L in the whole company, so we're a very elegant business model. So there is room for expansion over time. And so we'll have to wait and see, but it's a great business model that way, I think.

And on the topic of pricing and kind of value-based pricing, how are you guys thinking about the value-based pricing in this environment where the memory costs are going higher and the lead times are also stretching?

Yes. We try to -- I think that our philosophy is to be as transparent as possible. And so what do I mean by that? So we're very -- we try to measure a few times and cut once. So we try to see what's going on with components and memory being one of them, et cetera. Anything we can see, try to sweep it and do one price increase, and we did that earlier this year. I'm talking for the majority. But we didn't do just, hey, everyone gets 7% and we're done because that's very easy. They went through and said, okay, who has a higher percentage of memory in your BOM. We're not going to price your backlog because you've already committed those purchase orders. And so we're like, hey, if you have something that's related to an increase we see, we can explain to you, we have to raise your price increase to at least keep us margin neutral. We're not looking to accrete margin because we've seen that in some of the other people in the industry, the companies showing accretion due to -- I don't think that's how we want to work with our customers.

So we'll be transparent where it's applicable to the BOM, we'll have the commercial conversation. And the commercial conversation will weed out how much of that increase we get to keep. And we'll keep doing it that way. And so we'll see as we go into '27 if something else is needed. But we just try to be transparent so that it's clear the pass-through sort of mentality, I would say.

Let's talk about the other businesses. At this conference last year, you talked about some of Arista's measured efforts to diversify revenue, including tapping into the federal sector and investing in Arista's International business. Can you update us on some of these diversification efforts?

Yes. I think we're still -- we talk a lot about AI and a lot about cloud titans and neoclouds, but there are a lot of people who show up every day to make sure that the less sexy, boring, slower growth things are happening. And so part of this is international Fed, I think, is a very nascent for Arista given where we are. So federal is an opportunity, not just in the Americas across the world, I would say, from a public sector perspective.

But when we talk about geographies like EMEA. EMEA last quarter had 36% growth, which is a great growth quarter for Paul Jordan, the leader there. And that's a combination of the large customers flowing through the region. But also when you get to that kind of growth, it's in region for the region with enterprise, Neocloud, et cetera. So we're seeing some good traction there. We're winning new logos of enterprise and campus. We're seeing a lot of great neoclouds, for example, in EMEA. So it's a focus of attention. We dedicate headcount and growth from a go-to-market perspective, lean a bit more into channel partners. And so that's a slow, steady growth. And the rinse repeat for the APAC region, who also has a leader that's within a year coming from Microsoft, which is -- he's a great leader there, too. So very excited. I think it's, again, back to what are the growth trajectories for Arista. International is definitely one over the next 10 or 15 years that has a lot of room to grow.

Good to know. And on the campus market, you have talked about having -- growing traction in that market, winning new customers. First of all, where are we in the campus kind of refresh cycle?

Well, I think that there are some peers in the industry who let us know there's a big refresh cycle going on. So we're very excited about that. We're fairly -- we're only 5% market share. So I think you look at us going to $1.25 billion, we're -- I think we're coming in exactly when you're seeing a lot of the refreshes start. It's a 5-, 7-, maybe 9-year journey for the customer. So coming in right when they're starting to do their next cycle, which is super exciting. And that was just if we were talking about just the normal portfolio.

But then you can layer on some of the conversations on them getting ready for inference, which we've talked about, right, Tyson. So customers who are coming to us ahead of a refresh cycle are coming to us from a competitor because they're interested in how we can help them get ready for inference. They're worried about some of the security with the Mythos, Glasswing environment. So many factors drawing them to us. We're winning campus-first deals, like I was mentioning earlier. So a lot to be excited about. We feel we have the right portfolio. Velo Cloud has done very well, integrating from an SD-WAN perspective, coming into like a full year now with the company. So we're pretty excited. But that's a high-volume, low dollar multi probably decade, excuse me, growth. So...

I know Jayshree and Todd, they've talked about the go-to-market in terms of product versus go-to-market. And where are we in that stage?

I think that sometimes because we still have -- we're 12 years post-IPO. We had a large cloud kind of start to the company. We got into enterprise. And so we're not a heavy go through channel market to customers company. We continue to go direct fulfill through the channel majority-wise, and we're continuing to fund it that way. But back to the international, where it's probably most important. We have, with Todd Nightingale doubled down on who are the 10 most impactful kind of players we need to work with and how do we cultivate those relationships. So we're very excited by what we're seeing there. And I think you're just seeing Arista grow into their enterprise legs from that perspective. So it still stays in that 5% to 6% of revenue. That gives us a lot of dollars each year to invest. So enterprise headcount or go-to-market, we've definitely been investing in. So more to come.

And then software as a percentage of the total business, how do we look at that number over time?

But do you want to describe maybe how the larger customers go through their software purchases? Because it doesn't really change over time, right? It stays at this 18%, 19% because it's part of the operating system that goes with it to the customer.

Yes. I mean it's -- for our hyperscale customers, I mean, they've got a mix of things where they deploy like Arista Blue Box and they're going to run their own NOS or some kind of open-NOS for certain use cases that are better well commoditized. And then their mission-critical kind of high-capacity, high-demand workloads. They rely on EOS. But like part of that transaction includes not just software in the form of licensing, but also support, right? And so we have kind of single transactions that we do at the beginning of the life cycle every time. But as they're incrementally deploying and growing with that growth comes additional license and additional support fees that come in.

And then you get to the end of the life, they want to keep the equipment around the support renewals that kick at that point as well. So it's a little bit more of a derivative is kind of how I think about it than its own unique business model with independent drivers and independent growth factors. And so you should generally just -- I think Chantelle can correct me if I'm wrong, but I think you're just going to kind of see as our numbers grow, the software kind of revenue grows pretty linearly with it.

Yes, it stays in this, to your point, 18% range, 18% to 20%. It's not that we have a software division that goes and sells it independently. It's part of what we deliver in totality to the customer at this point.

Sounds good. We're almost out of time. Chantelle and Tyson, thank you for coming to the Citi conference.

Yes. Thank you for having us.

Thank you so much.

Great. Good morning, everybody. Welcome to the Arista fireside chat at the Goldman Sachs Communacopia and Technology Conference. My name is Mike Ng, and I cover Arista and Comtech here at the firm. It's my privilege to welcome Arista's President and CTO, Ken Duda, alongside Chantelle Breithaupt, who's the CFO.

We have about 35 minutes for today's presentation. But first and foremost, Ken, Chantelle, thank you so much for joining us today. It's an absolute pleasure.

Yes. Thank you for having us. Great to be here after a long weekend.

Yes. Exactly.

Well, to kick things off, Arista crossed a historic milestone last quarter with its first $3 billion revenue quarter. Networking is an absolutely critical part of client campus, data center and AI environments. So maybe start and talk about how you're balancing the strategic investments between scaling the core AI and data center switching fabric product portfolio versus what you're doing in software, campus and routing.

Yes. Thanks, Michael. We are so excited about what's happening in networking as the network is absolutely the lifeblood of so many different kinds of operations. And it's to connect everything together. When the network isn't working, nothing working is super reliability critical, and we feel like our opportunity to continue to grow and expand in that space is just really exciting to me.

And with regard to your question about how do we invest, one of the great things about our business is we don't have to think about it in those terms, right? It's not sort of like, well, we do invest here or do we invest there? No. What we do is we work very closely with the world's most sophisticated hyperscaler operators, customized solutions for them, bring in the newest technologies, you can see that now with XPO, liquid cooled optics and that sort of thing, get all that working at scale.

And then that -- those investments that we make in the hardware and the software, the technology naturally flow across the ecosystem into the broader markets, the specialty operators, ultimately into the enterprises. And so we're investing along the entire chain there. It's not a sort of A or B decision.

Yes. The only thing I would add to Ken's comments, which absolutely resonate with me in the sense of how we approach the company. It's a benefit and it's not confusing for our capital allocation strategy or investment strategy when you're just pure-play networking, right?

So we love all those children equally because they're all important in networking portfolio. And if you think about our guide for this year being $12.6 billion, roughly 40% growth, that's a lot of absolute dollars added if you maintain 8% to 10% of R&D to revenue for Ken and his team. So we're super excited, and we have room for all of those things to be invested in.

Great. I mean that's a fantastic segue. Maybe you can talk a little bit about that revenue guidance for this year. What specific customer demand signals or supply chain improvements and availability inform that upward revision? And where do you feel like you have the most visibility today and potentially opportunities for upside optionality?

Yes, sure. So Jayshree and I were super excited to raise the guidance by over $1 billion in the last call. And I would say 2 things were true to make that a comfortable position for us. The first thing was if I go back to the Q1 earnings call back to the scenario that no one thought was popular, but was definitely needed talking about supply chain constraints across the industry.

We got more comfortable with supply chain. We leaned into purchase commitments. We had some of our vendors rally that we needed to rally. And we had to make sure the team inside the company was on their A game to make sure this happen. So supply chain was something we're comfortable with, Michael.

And the second thing is by the time you get to that kind of August time frame, we have 2 quarters of PO transactional visibility, so we could see through to the end of the year. So supply chain improvements with PO visibility timing, those 2 things came together to give us confidence.

I think if you were to look at what could give us even more upside to that guide raise, it's that the supply chain eases up even more. I think that we're not out of the woods. I don't think anyone in the industry is out of the woods for supply chain constraints.

But if that gets a little bit more opened up, there could be some potential for upside.

Great. Are there any particular areas of the supply chain or component availability that would bring true in terms of things getting better, leading to potential upside?

I don't think it's because it's different customers have different things, but it's everything from some of the peripherals to some of the main things, main components that come into it. So we have agreements on chips and memory, but there's PCBs and there's -- sometimes there's power cables and things like that, that just kind of whack-a-mole through the year. So we'll just keep our eye on it.

Great. I wanted to ask about EOS and competitive differentiation. It's an important competitive moat for Arista. I think it's a competitive advantage when you put Arista against any white box vendor. So maybe you can talk a little bit about EOS, its differentiation and has that changed over the years as white box operating systems potentially get better?

Yes. The situation with open source NOS is that it may be open source, it is not free. It takes a deep technical expertise to actually get all the components together, assemble them into an image and get that to actually work on the hardware platforms and use cases of interest.

So I'm not foreseeing any deep penetration there outside of a handful of hyperscaler operators who I don't believe are even saving a single dollar here, honestly. What they're gaining is multi-sourcing of their software environment. They cannot accept the operational risk of being beholden to a single vendor. And that's the core driver, I believe, for what's happening in that part of the market.

The competitive differentiation of EOS is very strong in the hyperscaler use cases, we're seeing still good traction with EOS even as they attempt an open source strategy, especially in high-demand routing use cases where you need fast reconvergence, you need to deal with large routing tables. You need rapid convergence when something changes in the network, getting the hardware tables updated quickly.

And under the memory constraints of the platform, we see significant advantage there. But for the broader market, I don't even think the open source operating systems are a realistic option. And there, the competitive differentiation of EOS lies in the quality.

The fact that you can count on the software really working and customer after customer tells me how much they appreciate having the switch software stack that they can really count on.

And Ken, maybe just to follow up on that. Are there certain products or areas of the network stack where EOS is critically important, whether that be in the spine or the leaf or certain AI use cases, whether that be like scale out versus scale across? How would you just think about where EOS' competitive differentiation matters the most and shines the most?

Well, again, I think it's really important to think about the hyperscaler market separately from really any of the other market segments. The new cloud operators are in a different category. Certainly, the enterprises are in a different category. And part of the strength of Arista is applying the same software.

We have the same operating system, not just the same brand. It's the same code running across that entire spectrum. And the advantages that we bring vary across that spectrum. So there's not a simple answer to your question. I would say that what we see in the hyperscalers where we have the greatest differentiation is, again, in routing.

We have a very advanced routing stack, all the policy controls, all the different tunnel encapsulation types and MPLS stack that's simply not available in the open source world. Whereas with the Neocloud operators and with the enterprises, it's the quality of EOS, the manageability through CloudVision, having a single software that runs across all of their use cases, whether it's a campus use case, a WAN use case, a cloud use case or, of course, in the data center, having that consistency of operation is a really important differentiator for us as well.

Great. I wanted to ask about merchant silicon in your high-end Ethernet switches. You guys obviously have a really great relationship with Broadcom, I guess, most recently for the Tomahawk 6. What are the advantages of using merchant silicon versus developing your own from a supply availability perspective, has working with merchant silicon and the allocation risk associated with that been a concern at all?

Well, the supply chain, of course, is a great concern. We have supply, we have demand. You need them both. And it's an industry-wide problem. There's nothing unique to Arista about this. In the semiconductor side, in particular, the merchant silicon versus in-house silicon isn't actually the big issue because the bottleneck isn't the chip designer, the bottleneck is the fab, right? So that doesn't really trying to matter very much.

From a supply allocation point of view, obviously, we've been managing that through being aggressive with our supply agreements and our purchase commitments, and we feel good about our position there.

Arista has been a merchant silicon company from day 1. I think our focus has been to add value through the system and through the software, better software, better integrated into the system. We have many examples where our software unlocks capabilities of the silicon, which is not unlocked through other vendors because of limitations in the software stack.

So I think we've proven in the market that, that merchant silicon approach has been successful.

Great. That's very clear. Chantelle, maybe on gross margins. Arista has 2026 gross margin guidance of 62% to 64%, and you maintained that last quarter despite cost inflation, customer mix shifts. What are some of the puts and takes for gross margin this year?

Yes. I think that if we go back to our Analyst Day we had, I think, in October '25, we stated the 2026 margin guide to be -- gross margin guide to be 62% to 64%. And to your point, with all the different things that have come in, we still have that guide. So I'm very proud of the team to allow us to do that.

So what are the main components? The main components usually for us is end customer mix from that perspective. And then the other one, too, that I would say is coming into this year a little bit similar to our peers is there's tariffs this year, they have tariff refunds.

And so if you look at that 62% to 64% guide, maybe 30 basis points, I would say, on the year is going to be tariff onetime coming back into the P&L, just to be transparent about that. So if you think about the other pieces that are coming to mix. So if we talk about kind of the price component inflation side of it, our philosophy earlier this year was to measure 2 or 3 times cut once.

So we tried to sweep in everything we thought could happen in the time frame, component inflation, maybe other different tariffs, et cetera. And we had one price increase, but it was just meant to offset the inflation, not meant to be accretive to our gross margin, but to hold it. And we only applied that to POs in the future to customers that had significant pieces of their bill of material.

So it was pretty curated. It wasn't just everyone got -- it wasn't like, everyone gets a car, everyone gets a price increase. We're pretty segmented and pretty accurate on that one. And so those will start to come in those price increases as we work through the backlog into new purchase orders.

The component inflation comes and goes depending on our supplier agreements. And so we've tried to make that neutral coming into this year, and we'll see where we get in 2027 based on the market. But a lot of great work by the team, both the commercial and the supply chain side, and we've been able to steer the ship within that guide so far.

Great. And could you just expand a little bit on some of the price increases implemented by Arista to recover that cost inflation, whether that be timing, magnitude, types of products and anything you could talk about as it relates to next year's gross margins, just given some of the puts and takes on the price increase tailwind and then the tariff refund kind of, I'll call it, a reversal.

Yes, sure. I think that from the perspective of the price increase, the largest component is the memory in the current kind of conversation. And so if the bill of material had a higher memory component to it, we would have a price increase in that situation and explain to the customer, trying to be as transparent as possible how that kind of flows through.

If it didn't have -- not a lot of our products have high memory bill of materials, so those weren't necessarily impacted. And then you'll have some of the chips and some of the other factors that go in. So those were all averaged out to a particular product and particular conversation.

I think going into next year, I'm not guiding next year at this point. But I think from the perspective of -- I don't know if we'll have to do another price increase. We'll have to see. But hopefully, the one we've done will carry into next year and keep us margin neutral within the same kind of range territory.

That's great. Yes. Great. Maybe we'll follow up on something that you guys talked about earlier, which is the multiyear purchase commitments. I think last quarter, they nearly tripled to $9.7 billion. What does this component commitment talk about or reflect in terms of your confidence in delivering and sustaining and fulfilling the consumer demand over the next couple of years? How much visibility on the component side do you actually have?

Yes. So we're -- as a company, we get -- we have many different frameworks. Some people call us conservative. I would call us prudent. And one of the ways we're prudent is the way we operate our balance sheet. And so when we do lean into things, it is with intention.

And so our lean into the purchase commitments should be seen by this audience and those that will see this after as a demand signal, right? So that's a demand signal that you're seeing there. It's not that, that's all inflation on components, that's demand. So I think that's very exciting from our perspective regarding that.

I think that if you look at the visibility side, so our biggest component are the chips, and that's 52-week lead time, right?

So we're already leaning into fast forward a year from now. So how do I reconcile it 2 quarters of visibility, but I have 1-year lead time. The great thing about our portfolio is it's pretty fungible. And so it's not like we're ordering specific chips that we can't use or building specific products we can't offer a different customer.

So again, going back to the flexibility of the portfolio, the fungibility of the components, we feel very comfortable we're not walking into a large obsolescence inventory risk environment. And so -- and some of the customers we have, the larger customers, Neoclouds, hyperscalers, we're having 18, 24-month technology conversations, right, Ken?

So we have an idea of where they're going, and we're helping them design. So we directionally know without a PO in hand where they should be going. So we balance those 2 things.

Michael, if I could just comment. This is an example of how the alignment that Arista has between the hyperscaler side of our business and the enterprise side of our business is so useful because we've got competitors that have different business units going after these things with completely independent engineering engagements and then they're taking a lot more risk of component obsolescence than we are when we can utilize the same switch models.

Which, of course, obviously contain the same components across multiple use cases, multiple types of customers, they're operating at different time frames. Some are a lot more aggressive than others, as you can imagine, in adopting the new technologies. And so we have a lot of sort of room there to find demand downstream.

Great. Yes. That's very clear. And maybe just on the other balance sheet item that investors focus on a lot, deferred revenue. How much visibility do you actually have in the deferred revenue recognition into actual revenue? And does things like data center readiness, the availability of power affect your ability to recognize revenue in terms of your products being shipped?

Yes. So just to remind, because sometimes it's not clear to all, deferred revenue means it's been shipped invoiced and usually cash collected within the payment term. So that's what's in deferred. Sometimes people confuse it for backlog. It's already shipped. There's no supply chain issue because it's already been deployed.

So from that perspective, we have an idea. So deferred revenue is new use cases, new products, right? So right now, you think about what's left for Arista, it's scale out and scale across, eventually scale up. Those are new use cases, new product 1.6T. So those are the types of things, 800 gig that goes into deferred.

And visibility is as good as the expected time frame it's going to take to get to the revenue recognition of the criteria. So of course, we have an idea, but we don't determine it in the sense of when it actually gets accepted. So we'll have a time frame, usually within a quarter or 2, and it's usually landed pretty well.

But I can give you some anecdotes in the sense of what we're hearing, and I'm sure that you guys have many more than I do, given you cover many companies. But we had a large customer say to us, they actually had -- they said the 3- to 4-week delay that their data center stopped constructing because an employee was hurt, and they had to prove that the facility was okay for employees to work.

So that's almost a month gone already just because of an employee injury, which you have to take very seriously. So add the power, the cooling, the facilities, the cabling, there are many reasons why it can take 18 to 24 months for some of these things to be completed.

And so that's the average time frame each is bespoke. But every quarter, things are coming off being accepted and things are being added. And so I think that healthy kind of turnover, I'm comfortable with in the way that it's acting.

Yes. And just to remind us, the nature of the deferral, is it because you're promising a certain level of uptime and performance and it has to be in production for that.

Well, different things. It can be -- the thing I would say is the customers really enjoy it because we have skin in the game until they've gotten to where they need to get to.

We don't ship it, leave it and say, good luck to you. Not to

be flippant, but that's the opposite in that.

The customer has to accept the product as working in their case.

That's right. So it can be site by site. It can be performance. There's many different things for different customers, but it keeps us engaged in our SEs and our technical team engaged until they've gotten to because you think about some of these clusters are some of the largest in the world, right?

Great. I wanted to ask about Neoclouds. It constantly comes up as something when I do my channel checks and expert calls as like something that Arista is doing really well with in terms of a customer cohort, but maybe a little bit underappreciated.

So talk a little bit about the Neocloud segment. How is competitive intensity in the segment evolved? Are these all like net new logos? Or are they expansions of existing relationships? How important is Neocloud in your AI outlook?

No, we're very happy about the Neocloud. This is a great thing for Arista because this is where we can really leverage our expertise. We have built out some of the -- the interconnects are some of the largest AI clusters in the world. So we bring that to the table along with switches that are proven and the most reliable switch operating system.

So Neoclouds in some ways, are our ideal customer because they appreciate the best-of-breed capabilities. They have the mandate to get to the lowest token cost, which means optimizing across the full stack and not simply accepting a lock-in solution from a single vendor.

But at the same time, they really benefit from what we bring in terms of a fully tried and tested interconnect, including the load balancing, the ability in the scale-out network to deal with a multi-tier situation and avoiding the kinds of hash collisions that lead to fabric slowdowns in an unoptimized architecture, along with the manageability benefits with CloudVision and the ability to automate the upgrades and the rollout, the reconfiguration and sort of -- and get that sort of combined visibility to see CloudVision enables you to see simultaneously what's happening in the network with respect to queuing, packet drop, latency, bursts and flow data. And what's going on, on the AI server in terms of flow control, RDMA timeouts, congestion loss of retransmissions.

And so that sort of -- that visibility feature is difficult for the Neoclouds reproduce on their own. It's another way we add value there.

And then the only other thing I'd add to Neoclouds as the CFO, we're very excited about this market. It means a lot to us. But it's almost like a high-risk, high reward segment in my view. So we're very cognizant of how we enter into the terms and conditions.

And so -- because this market is not necessarily always proven out from a financial backing perspective. So we either walk away from the deal or we have prepayment scenarios, et cetera. So we're very clear and do we understand where the invoice is going to be paid at the end of the day, given the volatility of what you've seen because there are many NeoClouds starting and not all make it. So we're just very clear just to be super clear for the audience as investors.

Great. Ken, you talked about single vendor lock-in, and I'm assuming that's a reference to somebody who has both compute and networking. Maybe you could just talk a little bit about that. Arista is obviously an open ecosystem beneficiary.

What determines whether a customer is in a closed ecosystem versus an open ecosystem? Is there a specific customer profile that's more likely to seek out the best of breed despite who the vendor is?

Yes, for sure. It's about scale. Customers who are operating at scale have the mandate. They have the incentive of the business driver to do a full stack optimization. They need all the pieces to work together properly. They need the best of breed at each layer of their infrastructure.

And so what we're seeing is low-volume customers don't have that same mandate. They don't have the same leverage on building that kind of optimized solution, and they're more likely to go with a turnkey solution. There are also issues with allocation where you don't necessarily get your fair share of the allocation unless you buy the vendor's turnkey solution that creates complications for our customers and drives them more towards a single vendor solution if they lack the purchase leverage to drive -- to sort of split that apart, you know what I mean. So it's really about the scale of the customer.

Great. Very clear. We talked a little bit about scale across. You guys mentioned the importance of EOS when you think about things like routing tables. I think those things are related.

But you recently said that scale across was going to represent, I think, 30% of the $3.5 billion AI revenue target this year. Maybe for the audience, just define scale across. Is that all DCI, but for distributed AI training? What products go and scale across? And how do you see it scaling over the long term?

Well, since you invited it, I'll give a 30-second timer on AI networking. So you first have to separate out the front end from the back end. So on the front end, we're talking about connecting AI clusters to the other infrastructure. So Internet routing to storage, to the other systems of the tools, the sources of input to the AI, the training data, all that comes in through the front-end network.

And the back end is all about connecting GPUs or accelerators to other accelerators. So within that, exchanging all the model weights and the partial matrices and all the data flow, especially during training that's required for the training algorithms.

And then the back-end network has 3 parts. There's scale up typically within one rack, within one enclosure, connecting GPUs that are physically maybe on the same board or certainly in the same system. Then there's scale out, which is interconnecting many of those systems across many racks in the data center.

And then there's scale across, which is interconnecting at the back end, clusters that have essentially been split across data centers. And scale across has a lot more challenge than scale out in routing complexity and in deep buffering requirement because you need to get enough data insight to cover the full round trip between clusters that may be geographically distributed.

And so that drives the 7800R platform, I think you mentioned, and then the higher buffering and the higher routing capabilities of our more advanced platforms. And we're seeing very good demand there because our customers are facing very severe constraints in the power and cooling and just getting the data center space they need.

And so they're having to take what they can get. They can only get so much power in any one location, put as many GPUs as they can within that power envelope, and then they need to expand their customers larger. And that's where scale across becomes so critical for them and where we're seeing really good demand.

Yes. I think the only thing I would add to Ken's comments is we feel incredibly well positioned for this market, not that we don't feel for scale up or scale out, but scale across specifically because you need the hardware portfolio, you need the software portfolio.

And I would say the experience we have with some of the larger scale-out AI deployments and you bring all those 3 things together, and I think it positions us very well, and that's why you're seeing us talk so much about it in the scale across environment.

It sounds like that's accretive to margins given the complexity of that. Is that fair?

I would say that for the value provided, there's opportunity there depending on the customer and segment.

Okay. Great. On scale-up Ethernet, when does that become something that's more meaningful to Arista?

Yes. Scale up is such a huge opportunity for us. We have almost no share there now, as you probably know. But there's a standardization going on, which has happened so many times in our industry where you start off with single vendor proprietary technologies, moving towards open standards where Arista has been so successful.

And we see that happening now exactly in the scale-up network with ESUN. Ethernet, again, is coming to the table to take its fair share. And we expect to see -- we're really excited by our customer engagements there. There's early trial stuff already going on, but we expect this to really start to ramp probably the later part of 2027 and really see volume in early 2028.

Yes. I think it's analogous to when I was taking the role back in early '24 when I started, we were having the same conversations on pilots, trials and production for InfiniBand, Ethernet.

Exactly.

It's like -- it feels like a rinse repeat in the most respectful way to enter the scale-up market. So I think it will be a similar kind of journey. Great.

All right. Why don't we pivot and talk a little bit about campus. Arista raised campus revenue target for this year to over $1.25 billion. What specific value props does Arista offer relative to incumbents? How much of that growth is cross-selling into some of your very happy data center customers versus net new enterprise logos?

Yes. Thanks, Michael. Campus is a great growth opportunity for us. And the value proposition fundamentally the same thing. It works. We have a level of quality there that is unmatched in our industry. And we -- and again, we've captured by having the same software stack, very similar hardware platforms, unique power over Ethernet, hardware platforms are not identical but they're very similar, built by the same team, targeting data center, targeting campus.

And having the same software and the same hardware architectures across that whole thing means we're able to leverage our experience, our success in the data center into those other market segments, not just from a business point of view, but from a technical point of view as well.

Having the same CloudVision management stack, it manages data center networks. It manages campus networks. It manages both together, providing end-to-end flow visibility. So if you're troubleshooting a client over WiFi going through a campus network across the WAN into the data center, trying to understand what's going on there, if you've got one system, that's a lot easier than if you have 3.

So we bring that consistency of operation, that EOS quality and to the campus networking problem. And our early campus customers were basically people who said, we love you so much in the data center.

Could you please make some campus switches because we're already taking your data center switches, putting them onto the campus using POE power injectors because we want to get the Arista value proposition that much.

Our early customers were largely data center. But more recently, we're seeing bigger and bigger fraction of new campus logos, people coming to us because they're so frustrated with their incumbent vendor, their quality problems, the licensing contracts that they're putting them through. So we're getting a lot of campus first deals as well now.

Yes. And just to kind of close on that, we're starting with a roughly 5% market share. So for us, this is high volume, lower dollar, steady growth over many, many years to come. And the fact that our portfolio is recognized on its own to not even need to be in the data center is, I think, a huge validation for the team. So I would say look for more in this space, right?

And on the campus piece, is it really just Arista getting their fair share because to your point, you're not there yet? Or thematically, are there campus switches and wireless access point drivers from security concerns, Ethos, WiFi 7, like product cycles, just anything that you would call out there?

Well, I think if you -- the way we kind of package is we call the cognitive campus. So it's always on to Ken's point, it's always on, zero touch operations and zero trust networking. And so I think you could talk about each of those 3 things as how it's a competitive advantage, the way that we're approaching it.

I don't know if there's anything you want to talk about the always on piece of it, but the same time, upgrades in the sense that you don't have to.

Yes. I think that's consistency of operation is so important. And the fact that you can use the same CloudVision provisioning automation to roll out a new set of branches or a new campus deployment. You're also using to roll out new racks, new halls in your data center. It helps our customers simplify their operations.

And you don't need to have downtime to do the next upgrade, right, which is pretty significantly different than our competitors.

In-service software upgrades in the campus, I used to think, hey, it's a campus, people go home at 4 in the morning. You can just upgrade the network then, right? Well, it turns out there are a lot of 24/7 operations out there.

And the whole thing is your security systems, your telephone systems, all your HVAC systems is all running over that same network. And in a hospital, in a manufacturing facility, in a logistics center, in a media distribution center, this is campus gear with a 24/7 requirement and our in-service upgrades, which we built for the data center.

I didn't think they would even be useful in the campus. They turn out to be a major differentiator. This is another great example of how we gain leverage by having a consistent portfolio across all of the different domains of the network.

Maybe 2 more questions for me. Chantelle, how are you thinking about capital allocation at this stage, buybacks, M&A, potential working capital investments to potentially increase visibility into supply availability?

Yes. I think that in that order, for sure, I would prioritize working capital. We're going to go through fluctuations. We're at step function growth, right? When you're doing 40% per year on a company that's 12 years old, that step function.

So absolutely working capital will be the theme for the next couple of years as we work through this new stage of growth, which we're very excited about. The buyback philosophy for Jayshree and I is opportunistic. So we'll continue to watch and see what makes sense.

But we're okay to have the cash to work through the working capital at this moment. And then M&A, M&A, lots of things are brought to us. We haven't seen anything that fits both the tech and the culture that we need.

So if there's something that hits that Venn diagram, always excited to look at it, but nothing specific at the moment.

Great. In the last minute or so, to close out, as you both look out at Arista's multiyear product road map, what specific technology or market opportunities are you personally most excited about? Ken, maybe you can kick off.

Oh man. Yes. So I'm a software guy, the program in my whole life and the AI coding assistance were eye-opening in the capabilities of this technology, a technology which has been so great for us from -- on the sell side, you're selling into the AI networks, I believe we can also incorporate into our products and create a network engineering and operations assistant with the same kind of impact as AI coding systems have had for software engineers.

And this is going to be a real important driver of our mainstream customer, improving their efficiency, improving their uptime, improving their operations through AI solutions.

Yes. And only thing I would add to that I'm excited about, just to close out is Arista is made for AI for networking, scale up, scale up, scale across, trading inference, front end, back end, [ Meta's ] environment, you name it. We stay true to the networking, and we're very excited about where the AI journey can take us. Thank you.

Great way to cap it up. Ken, Chantelle, thank you so much for being part of the conference.

Thanks, Michael.

Thank you.

Welcome to the Rosenblatt Age of AI Tech Conference, fireside chat with Arista Networks. I am Mike Genovese, the cloud and communications equipment analyst. Super happy to be joined by some of the management from one of the very best companies out there. We have the Chief Financial Officer, Chantelle Breithaupt; and Brendan Gibbs, Vice President of Product Line Management. Nice to see you both.

Yes. Thank you. Thanks for opportunity.

Great. And so I'm going to ask questions. We've got 45 minutes, but I also want to let the audience know that on the audience screens, there's a widget in the upper right-hand corner, where you can type in questions that will come to me, and I will ask the team here any questions that I get from the audience. So please feel free to send them in.

But let's get started. So we're going to talk about AI, obviously. And Etherlink, which is the Arista's family of AI-optimized networking, high-performance platforms with advanced software has gone from only 4 or 5 customers in 2024 to more than 100 customers today. Can you kind of break that down more for us by customer type, whether cloud titans, AI labs, neoclouds, sovereign enterprise. And where is the incremental kind of AI fabric revenue coming from going forward versus the first half of the year?

Yes, sure. I can start off, and Brendan will tag team these as we go through and make it conversational. So let me just take a step back. Like how proud we are to say, hey, we had the Etherlink portfolio, June 2024. I remember our 6 months in, we're at our New York Stock Exchange event. And not only did we have a great kind of analyst conversation, but we had a great product innovation reveal. And so I think it's just indicative of how we feel Arista was almost born for this AI moment.

First, we had the cloud and now we have AI. So even take the Etherlink portfolio you referred to, Mike, what a great robust set of products unmatched by any of our competitors. We give our all the different customers you mentioned segments, options for their AI journey at a minimum. So we're super thrilled. So now to get to how are we getting to this $12.6 billion, 40% revenue guide that we're very excited about. It's coming from all these sectors. The thing is that we are seeing -- if you're talking about like what's changing in the second half versus the first half, it's more of the same or even versus last year.

It's just more of, more Neocloud, more Titan, more AI labs, more enterprise, more campus, although campus isn't quite AI yet, but just generally in the $12.6 billion. And so those first few customers, we were talking at that time of InfiniBand and now we're only talking Ethernet.

So the fact we've been able to go from those large customers to a breadth of customers, I think is super exciting in showing that for a pure-play networking company, we can serve any of those use cases and continue to drive the innovation. Going into next year, we'll talk more about scale out, scale across and scale up, and Brendan can give you more of that through your questions. So we're just super excited whether it's trading in inference, front end and back end, scale up, scale out, scale across. We're going to meet the customers where they need and really help them achieve their AI outcomes.

Great. So you touched on it a little bit, but just kind of flesh out more how you would characterize demand right now. Is this a really true -- I mean, it feels to me like it is, right, a genuine expansion of deployment and plans and needs for the network and the data centers. But we also have this supply scarcity issue. And in the pandemic, I think maybe that great if we look back on it for certain companies created pull forwards. And so is any of that going on? And how do you kind of as the CFO look at your dashboard and kind of tell the difference between expanding demand and just pull forward because we're worried about supply?

Yes. I think that mostly it's from the customer engagement, I think, Mike, because for -- if you think about -- we mostly serve large enterprise and larger, right, than that, so you're talking large enterprise, neoclouds, AI labs titans. So for the majority, we've been having ongoing conversations. And so we would get a sense of if they felt they're pulling it in because of supply. I don't think that's the environment.

I do think sometimes people are pulling in early because they want to make sure that they come to us as a company to help them in AI environment, so they might pull forward their enterprise renewal because of methods, they might pull forward their scale across because they just have to get to outcomes faster we don't see pull forward at all, but if we did, it would be more from a demand expectation. We don't see it on the supply scarcity.

So my dashboard is customer conversations. It's project evolution. It's in the sense of its 52-week lead times. So I think customers are going to lean into 52 weeks unless they're pretty certain that it's something. I don't think it's very easy to pull forward with those kind of lead times. And so we're very clear and very excited about the demand environment. And even this year in the guide, if we can get a bit more supply, we could even go a little higher than the guide.

Great. So I mean, look, I've covered the stock for a long time, longer than just the past couple of years. But I've gone through my own journey with Arista and AI in the last couple of years because when we were just first modeling and talking about the back end, and I was looking at Ethernet becoming like InfiniBand and I thought like -- but where is the value of the software here? And does that change the story. But I don't know if it's front end versus back end and inference versus modeling or if it's actually -- there's a different explanation for this.

But the value of the software portfolio and the features and the new stuff you put out has persisted and changed my mind and maybe more of a believer in the last year or so. So can you talk about kind of use cases for software versus Blue Box? And it seems like they're both growing in the company, and there's lots of cases for both, but I'm talking too much. I want to hear this from you.

Brendan, do you want to start?

Yes, absolutely. I mean first of all, I'm mindful of what Chantelle said, we announced our Etherlink portfolio back in June of 2024. That was 800 gig only that was scale out. It seemed so long ago at this point but the portfolio has significantly blossomed the use cases have expanded since then. What we found is that EOS or operating system software has such a attraction for our customers, primarily because of like the most basic value proposition, which is speed with quality.

AI is essentially an arms race. All of these customers are racing to get to market, racing to sign up customers racing to innovate at the frontier of models and cloud expansion and GPU as a service, et cetera. So having that software foundation for the network from us really gives them peace of mind and get some quicker time to deployment, time to first token and they just stay up and active. So that's the first level highest level deployment value.

What we've seen is that the -- not only the quality as I'm saying, but also the intelligence built into the software, the analytics that we embed to give customers insight to what the heck is going on in their clusters that pays off in dividends over time so we can unlock the greatest performance, the greatest GPU utilization and the greatest insights to what's happening in their clusters.

So as they've gone from the initial small highlights of scale-out clusters and they've made them large, EOS has grown with them. And they've -- we've been able to unlock that speed with quality paradigm for them, so they can drive the scale of their clusters a pace. And then as they've found themselves restricted by one physical data center, and they need to scale across the multiple data centers and AI centers. We've grown with them there, too.

And there's incrementally even more value than the EOS operating system software for them for that with routing intelligence, with wire speed encryption with more insights across a wide area. So the expansion of the use cases has fit with expansion of our portfolio from 800 gig to 1.6T. And now with more and more intelligence along the way, EOS has remained relevant and even more so over time.

Yes. I just don't want to double-click there on scale across because it is turning into such a big market. And obviously, things like 800G ZR pluggables and the optical line systems and now coming the multi-rail amplifiers, right? Those are supplied by the optical companies. And you kind of had this impression well, these ZRs will just plug into available switching and routing for companies like Arista. But I guess there isn't -- there aren't just ports lying around ready, they actually need to deploy, it seems like many new switches to do this scale across. Is that -- am I thinking about that correctly?

Well, in some cases, yes. So if I think about a scale-out cluster because that's where it's run from going back in time and it's not that long ago, you've had these modular high-end spine platforms with tons of ports. And that's one of the hallmarks of differentiation of Arista is these high port radix modular platforms. In the old world for scale out, all the ports just went south at the leaf nodes. But as the data center gets large across multiple geographically dispersed data centers and scale across comes into play, now you just turn some of the port sideways, so to speak, to go for data center interconnect.

And so what you have is instead of a spine remaining local, your spine becomes geographically dispersed. And so in some cases, yes, you're right, you need to deploy new platforms. In some cases, it's taking advantage of the high port capacity to maybe plug some of the ports in with ZR and ZR+ coherent DWDM pluggables. So the great thing about us is that we work with a broad ecosystem of pluggable providers we offer the true differentiation for that scale across domain of the encryption-based hardware platforms with all the routing software intelligence and diversity of optical plugs whether it be from any of the coherent providers, we can work with any and all of them.

And does EOS is important for that entire now network that's one domain but across multiple data centers?

It's important and more so than ever, absolutely because now you need to arbitrate whether a workload stays local or remote. And if it goes remote, how do you properly preserve and prioritize the transmission so that you don't have any sort of congestion. It's difficult but easier to manage congestion and have no packet loss locally, but now if you're going across hundreds or thousands of kilometers, it's even more difficult. And if any problem comes up, it's going to be seen immediately. So the routing intelligence and analytics becomes even more paramount, even more complicated, but we're -- we've risen to the challenge, and we've got scale across now at about 1/3 of our business is part of the most recent guide.

Right. So that's getting to the point, which is this is creating incremental demand for switches. But I mean it sounds like -- I mean, you need to use up the existing ports or anything you have left, but then put in new -- put in new switch.

Yes. And we're identifying it as a distinct use case. And for sure, it is. But also another way to look at this is just gigantic clusters. What used to be smaller, inside of one physical building is now gigantic, like I say, where the spine becomes distributed across many data centers. So we identify that as a scale-out cluster or a bit large across many sites. But yes, it's a new use case. It's expansion. It's more ports, more systems, more software intelligence and more value.

Yes. So when this -- when we first -- on the street, started talking about this market, which wasn't very long ago, right? I think that the vendors are trying to jump to the top of the mind that are really going to benefit here on the optical side, Ciena and on the switching and routing side, Arista. Now we've also seen on the optical side that it's helping Nokia, and it's helping Cisco as well.

And -- but on the routing and switching side, in terms of actually moving the numbers it seems that it's really working for you guys, maybe a little bit at Cisco, but I mean, I guess my question is, a, do you think this helps all of the routing and switching vendors? Or is it somehow more particularly focused on you because of the 3 major hyperscalers who are ahead on scale-out are your customers, right, to long-time customers, I think 1 newer customer? I mean, is this something that's going to help all switching and writing vendors? Or does it so somehow more share of it go to you and you get more than your share?

No, it's definitely a scenario where not all vendors are created equal in this context because before you can take a data center and an AI deployment and scale it across, you actually need to win first that back-end scale-out cluster. And Arista is one of the most successful vendors deploying large-scale multi-customer back-end trending clusters period. And so when it comes time to take that cluster and expand it across multiple geographically dispersed sites with scale-across. That's absolutely within our bailiwick.

It's more than just putting on a cap that says scale across on the top and saying, "I've got a routing box too." I've got a coherent pluggable like I'm a scale across vendor because they didn't win the scale across deployments -- or sorry, scale-out deployments to begin with. So it's not just scale across is a perimeter routing, one box or one DWDM transport node, it's the whole cluster writ large.

So there's very few vendors who have had those type of large-scale back-end scale-out clusters and Arista is one of them, especially from an Ethernet perspective, we're absolutely leader. So yes, it's not a all vendors are in an equal scenario. This is very much advantages us because of our success in scale-out and now our intelligence and capabilities for scale across it just becomes natural.

Great. I guess, as long as we're talking about these different scale out, which is what you've always done. The scale across is already moving the needle. And I just need more help understanding we have scaled up for switching and routing, right? We've done a lot of work on what does it mean for optical and the optical content that goes in and replaces the current electrical content in these racks. I don't really yet understand ESUN and what that opens up for you guys. And I know that it's not happening tomorrow. I mean, pretty soon, but not this year. So just help me understand not just the timing, but actually what it is. And when it does happen, how big of an opportunity it is?

So I can take a stab and then Chantelle, I'd love for you to jump in too.

Yes, go ahead.

At a high level, there's multiple industry analysts, but I've seen it in as high as like a $20 billion market just for Ethernet scale-up networking by 2030. That's an industry separate analyst report, but that's compelling as a market size that we want to go after and pursue. So we're putting our money where our mouth is, so to speak. We're investing in pursuit of scale-up networking for Ethernet. We see there's a huge opportunity for the non-NVIDIA ecosystem of Ethernet attached XPUs where you need some sort of facility to create that kind of coherent memory on the back end between all of the different XPUs in a rack.

You need some sort of high-speed interconnect, and we think Ethernet switching is really well designed for that. And so I think that, first of all, it's an attractive market, it's potentially a large and lucrative market. We're helping lead the definition of that market to begin with, where we helped invent and popularize the whole concept of Ethernet scale-up networking one of the software leaders and architects from our company is the co-chair of the ESUN Network Working Group as part of OCP.

And not only do we have the industry standardization, not only do we have the Ethernet prowess for kind of consistency of AI fabric from scale up to scale out to scale across, but we're also bringing to bear a lot of the hardware engineering prowess that we've got from our modular chassis over the last couple of decades, we're bringing that to bear at this new level of complexity for scale-up networking within a particular rack. So the opportunity is significant. We think we've got a lot of software and hardware differentiation and unique expertise to bring to bear.

Yes. And the other thing I would add, that's a great like technology description, Brendan. So thank you. The thing I would add is think about when we were talking 2 years ago, kind of the Ethernet and InfiniBand, there's going to be some segmentation and scale up, we believe they'll be proprietary NVLink. There'll be some kind of white box equivalent for the lowest needs. And then there'll be a value-add Ethernet, which we hope is us as the branded vendor.

So we see that segmentation maintaining. And we got to the point of announcing to be in scale up because we had almost like a crowd sourcing from our customers, "Hey, we said can you think about getting into this space as an Ethernet leader." So there's a bit of a pull and a bit of an innovation, let's get there, sort of a combination between us and some of the customer base.

And so that's where ESUN was born, and I think that's a great thing. It will not be material in our '27 financials because we do have to get the ESUN standards and do pilots and trials. But once it gets going, in '28. We hope it's a great new segment. And when we update our TAM, we'll give a shot as to what we think that can be.

Okay. Great. I got a question from the audience, and I'm just going to read it. And the audience -- the questions are coming from the audience are different than the questions that I would ask. So...

That's fine. Yes.

Let me just read it. Historically, Arista has discussed the customers who prominently use white box will continue to pursue that strategy. Is this still the case? And what could happen that would allow you to win meaningful business at these customers?

Yes. So generally, generally, the white box environment is not an environment we'd want to go after because it's not -- it's kind of overpaying for technology for places where it's low use in the network, right, Brendan. So the white box use case remains the white box use case. Having said that, there's probably somewhere a little bit in the middle where it's -- the operating system that sits on top of that will be a difference as we go and kind of maybe into these mythos environments. So maybe that's where it gets a little squishy for lack of a better word in the sense of where that will meet. But we're not looking to enter the white box business that has its own use case in any of our customer designs. Brendan, anything you'd want to add?

Yes. The only thing I would contribute is we should think about why because some of the customers went for white box to begin with. There are some that went white box even before Arista was a company they're going to persist with that strategy. But I think white box persisted for those companies because it was high volume and it was low entropy. Like the complexity didn't change overnight. It was a well-known commodity, and there wasn't a lot of technological change or innovation. So they could just stamp out in high volume and save themselves a couple of pennies.

As we think about the AI trade, that doesn't necessarily hold true, meaning that there's so much entropy of technological innovation, so there's an opportunity for some of these customers to think differently. That's what we're hoping. We think that the speed with quality value proposition that I referenced for our branded EOS-based operating system and platforms has utility in such a world where innovation speed is off the chart, where white box may not be as attractive because you need not just a white box hardware platform, but you need an open source software, need all of the features added to that by somebody.

And then you need to find quality and you need to find time and speed and maybe that doesn't all work together. So it's possible that in the future, as Chantelle said, we're not going after white box, but some of the value drivers for white box may no longer be as valid, and we would love for them to join our ecosystem.

Another question from the audience, which follows up on this as well as the last question and the end of the last question that you commented on Chantelle. There's some chatter that the nature of scale-up domain lends itself a bit more to the white box model. Is this true? And how would you characterize opportunities that are attractive to you in the scale-up domain?

Yes. So I'll start in the sense that we do see that segmentation coming in the sense of a white box equivalent scale up, a proprietary NVLink that eventually transitions to Ethernet just like InfiniBand has done and then the value-add Ethernet. And then maybe, Brendan, why don't you take us through like what's that value-add Ethernet scenario?

Well, the bear case, so to speak, like Chantelle is noting where you might want this white box would be where there's not that many features. The bull case for us would be where our customer values consistency of operations, where they've already got EOS deployed for their scale-out network. So having consistency stamped out the same way for scale up gives them a very rapid deployment. It's already qualified. It's already proven to work.

So turning it up for kind of the new world scale up makes it even easier because we shouldn't pretend all of the people in a non-NVIDIA ecosystem going with new XPUs, it's all new, stating the obvious, adding yet another new thing to the mix of an open source operating system with white box add extra risk and complexity. So the opportunity for us in that segment who might want branded is that we can give them that speed with quality to get deployment and just remove one variable from an otherwise net new and complex thing.

Yes, for sure. And if you think about all these customers to whoever asked the question and Mike, all of these customers are racing to get the most compute to get the best economics they can. And part of that is utilization. So whether it's scale up, scale out, scale across, we feel open source Ethernet is going to get them the best utilization, the best outcome, the best economics. And I think that's the ebb and flow you're going to see as they work through their business models. So we're very excited to help them.

Great. Great. Let's move on to some other questions. Just 1.6, which I think is trialing right now with large customers. You said volume production in '27. I think there's a lot of things that all have to come together to make a new platform like this work. So -- basically, just any more on the time line of 1.6? And are you -- and then as we talk about NPO and CPO and the potential for open standards, NPO, CPO, is that -- how does that layer into the 1.6 product over time?

So I would say from a timing perspective, as you noted, trials are going on now volume for next year. From a technology perspective, it's relatively straightforward in that we can still, with this generation, have both air-cooled and liquid-cooled options. So there's no sort of blocker from a technology impediment perspective where everybody's got to go liquid, not everybody is ready. We have air-cooled systems we've already announced it publicly.

For those people who want liquid cooling, again, we've announced that as well. A lot of the liquid cooling requirement is going to be driven by the compute nodes. So we're not going to be the tip of the spear for that, people will have deployed in ones in liquid cooling for the compute nodes, that will likely be deployed before any of the networking gets deployed to interconnect them.

So that's, again, likely not an impediment. It fits into the overall build-out that Chantelle and Jayshree have been very circumspect describing for a long time, which is data center build-out and powering and facilities build-outs, they're all out of our control, but a lot of that will be done before we get there. So I think 1.6T is here. The optics are here for that from a local connectivity perspective and 1.6T ZR for scale across probably next year.

With regards to NPO and CPO, it's a technology set of options we're looking at very closely. We actually announced earlier this year at OFC, we announced something we're calling open CPO. CPO, of course, is co-packaged optics. We also announced at the same time, technology called XPO, which is our pluggable high-speed liquid-cooled of 1.6T option.

So in that case, again, we're trying to innovate for the industry, and we're trying to give choice. If a customer wants CPO and they're just bent on that decision, then Hallelujah, in that case, we would offer open CPO, which offers serviceability and multi-vendor options for co-packaged optics. So that you're not locked into any one solution, and it's not a value proposition to throw the whole switch out if something fails, serviceability, we think, is critical there.

But XPO is a complement to that in the sense that it's fully serviceable, it's pluggable. It's liquid-cooled, like I said, and it offers every sort of laser available from short range plus LPO and ZR, ZR+. So we believe in choice and we think that with 1.6T with open CPO and XPO are giving our customers tons of choice.

Great. Great. Chantelle, can you just talk more about supply? I'm going to leave the question very general and not give too much of a lead-up here. Except to say that after the first quarter conference call, investors came away more concerned about that supply could hold back the growth of the company and then seem to feel better about it after the second quarter. But how do you think -- how do you deal with the challenges to supply? And how worried should we be?

Yes. I think that Jayshree and I'd like to focus on the demand and how the demand like morphing and growing and shifting. And we're super excited about the demand side. We think it's definitely a demand-driven market this year, and it doesn't stop on December 31, we see it going into next year. So we're super excited. No one likes to hear, hey, you've got a lot of demand and it's being a little bit constrained. And so I understand, and we deal with the information we have in a moment. So on earnings call, we talk about it in the next earnings call, we're seeing some development. And so we try to be quite transparent even though not everyone likes to hear it, we need to be honest.

And so I think from a supply perspective, we're happy that we've done some great work in our vendors in our ecosystem have done great work to help us get to this 40% revenue guide, which we think is tremendous. We're very excited about that. And if we get a little bit more, maybe we can do better than that. The supply is not unconstrained going into next year. It's a little bit of a whack-a-mole like you hear Jayshree and I talk about. So hey, the larger we get the more power we have, the more conversations we're getting. So it's like this really great snowball effect in the sense of what we can get done. And so we're super excited.

And I think that I don't expect it to be a topic all of next year, but we did have to be a bit realistic. And I think you heard other companies after us start to say, "Hey, yes, we see a bit of that too, and so we'll work through it." But the demand, we're excited, and we'll find a way. It's a when, not an if in our expectation.

So I worked in -- I mean, it's been almost 25 years since I've worked in the industry because I worked at Ciena before Wall Street. But I do remember some things, and I've obviously been following these companies since then, and I know that you win customers and that does create stickiness and opportunity for a while, but particularly given how fast things are moving these days, right? There's -- and in this supply-constrained environment, it's customers want to -- they want a good solution and they want to buy as much as they can possibly get, but they're always planning on the next solution.

So there's always -- so when I think about your revenue growth rate, I mean, I know you're not going to give guidance for next year until June and then will start lower and then will move higher. But from my perspective, yes, 40% next year like no problem. But then I start to worry about '28, because I don't think that's a done deal yet, right? I almost feel like '27 is -- the demand is there. If we -- the supply is there were going to be good. But I think in '28, '29, we have to keep competing with the NVIDIAs and the Ciscos and the Celestica and the white boxes, and we have to keep winning always winning new deals for '28 and beyond. So is that a reasonable way to think about things? And how confident are you in kind of the next round of wins?

I think that I'm confident in the sense of if there's a market we're going to do well. So I can't tell you my team what the market is going to be in '28 and '29. Everything I see from the industry analyst side that 2030 looks great. Maybe that's a little optimistic. But the thing to think about is if, let's say, there's always a demand for networking and we have this additional really great layer on the cake that it's more complicated and it's for AI.

So if we think AI is going to be something in some shape or form for the next 5 years or in perpetuity. We're going to meet wherever it's at. We're going to meet the front end and the back end. We're going to meet the inference and the training. We're going to meet the scale up, scale out, scale across.

So the thing I think is really unique about Arista being only focused on networking and nothing else is that we'll cover any of those networking needs. So maybe 1 or 2 or 3 years at these large scale across. And then, hey, there's 5 years of really great enterprise inference and would they love to have 1 EOS to put all their API, Agentic AI units into it and have one really great experience and be able to cover against things like method.

So I think, Mike, it's wherever AI takes us is where it will ebb and flow, but I think we have a really good shot in any of those AI scenarios. And so I'm not going to guide '28. But if there's a great set of things going, we'll be ready. And I think that's our responsibility and our excitement as a company. We're not distracted with other things we're trying to prioritize.

Anything to add, Brendan, just from a competing out for opportunities down the road?

You're 1,000% correct. We don't sit on our laurels at all. This is something that internally we're paranoid about one of the things Arista has been amazingly successful at in the past, but never stopped innovating for the future is the pace of innovation. From an enterprise data center portfolio, we've always had the most broad portfolio, same thing from a hyperscaler and cloud perspective.

We've got fixed platforms, modular platforms, shallow buffer, deep buffer. We've got something for everybody and every architecture that a customer might want. We've shown an ability to innovate at speed across a broad swath of the portfolio, and that's as Chantelle said, because we're a networking specialist. We've got the heft to be able to execute an investment in parallel across multiple dimensions and across multiple generations.

We just announced 2 years ago in June 2024, our 800-gig portfolio, we've already announced our 1.6T portfolio. We're continuing to innovate. And as AI has grown in use cases from just scale out to scale across to next scale up. We're investing for all of those as well. So that is what we see gives us that opportunity to continue to compete for every customer.

To be sure, we've got long-standing partnerships that hopefully advantage us for future opportunities. but we're always going to keep investing from an engineering perspective to make sure we've got the right products at the right time. And from an operations perspective to make sure we've got the supply chain product to ship when a customer may want them. They have to work hand in glove, and we've got both parts of that engine firing in parallel.

Okay. Great. I was going to ask you a gross margin question, and I got one from the audience. So I'll ask the audience's question. How do you think about gross margins in with the hyperscale mix, is that more than offset by scale across? Any other puts and takes investors should keep in mind for long-term gross margins?

Yes. I think the number one thing to keep in mind is mix, that is the gross margin driver, and we try to be conversational about it every quarter. So mix is the number one item and mix. We have 2 quarters of visibility. So going into next year, what I would say is and tell you here, definitely, kind of the 62% to 64% range is the range to assume, right? So unless we have different set of parameters that get us in a different direction. The 62% to 64% range is what you should assume.

The only other one-offs that can be 20 bps here or there would be something like tariff refunds where you have these unusuals that kind of coming in and out, but those are 20, 30 bps at the most. Generally, it's mix. And so because we serve this wide segment of customers and industries, we usually try to balance all those things out. If we have an over rotation on something, we'll talk about it, we'll be transparent. It's still great to win those deals and have those deals and be in the 60s handles as my bought. So -- but 62% to 64%, unless you hear otherwise, is probably the band to think about.

And then I guess on operating margin, could you just answer if I ask the question about operating margin instead of gross margin, anything to add?

Well, I think, hey, you know that we're only on networking business unit, the whole company. So in the sense of I'll always ask Andy, Ken, and Todd, would you guys need from an organic investment perspective, so it's R&D, sales and marketing, hey, ask what do we need to scale the company. But when you're growing 40% a year, that's a lot of absolute dollars, right, as a sense of you don't necessarily scale your headcount.

So there's leverage to be had there. And so I think we'll guide next year as we get there. But I think we're pretty happy with the guide this year being kind of in that 48% to 49%, maybe there's a year of some investment that makes that different, but we're kind of in this high leverage state at the moment. So we'll see where we get to for '27.

Okay. Just over the last couple of quarters, I've been a bit confused by price increases that can go through because customers realize that memory and other things have gone up. But what I don't -- and it kind of changes company by company was do price increases? Can they actually help the gross margin? Do they just keep the gross margin kind of flat where -- when input prices go up, how do we think about the impact on price increases?

Yes. I think it depends on the company philosophy. We've held 62% to 64% as our range since Analyst Day, right? So we've had a pretty tight and not really changing that for a while. And so since then, we've had kind of this price increase conversation on some of the components to your point, Mike, our philosophy was 2 things, two-pronged philosophy. First was to try to cut twice measure twice, cut once. In the sense of let's think of all the things we know up today and do one price increase. Let's not do the backlog because they're already placed, let's go forward. So that's a philosophy.

The other philosophy is to not try to make money off of our customers for a moment in time that's beyond our control in there which is the supply chain moment. You can gain accretion in your price with some confidence if it's a tech valuation that you're giving them. You're giving them something more that helps their TCO, et cetera. Our philosophy is to only pass the price increase along that we're experiencing to hold margin.

So if it was 65% before and the price increase, we're going to try to keep it at 65%. We're not going to say, hey, we have a price increase. We're going to give you the price increase and plus something to make our margin accretive. That's just our philosophy. So I think it depends on the company's philosophy at the end of the day.

Okay. And then how should we think about deferred revenues in the second half of the year? Or is that -- I mean you really raised guidance for the second half of the year. But just help us think about what deferred might do in the second half.

Yes. So I always say deferred can come up or down on any quarter. So I will keep saying that because it's going to happen at some point, and that's just how deferred moves. Generally, I don't guide deferred, but I can tell you, I anticipate, I anticipate deferred to end at a higher balance in Q4 this year than it did Q4 last year. So generally on the year going up is kind of what I can tell you. But I don't guide and there will be ebbs and flows every quarter. But generally, you should see it as -- it's complementary to the P&L growth kind of -- it's another demand signal at some point in time, it's going to come to the P&L, right?

Okay, these things are moving scale across, scale up. I mean even scale out, right? I mean, new customers, we should think that there's going to be new projects that go into deferred revenue all the time, right?

Every quarter, every quarter, every quarter. The great thing is that there's nothing there that I'm scared has aged past expectations. Like if I was to ask myself hard questions, I mean, like is there something sitting in there that sat there too long? Is there some issue that you see? And so it's been a very healthy within a quarter of expectations generally flushing through. And so I think that just shows that it's working from our innovation, getting to acceptance by the customer.

Absolutely. And also just remind me how to think about your 10% customers and customer diversification. I mean as you win more customers, people are following are you going to have new 10% customers, you have new 10% customers, but over time, I don't know if that will be as important. So how do you think about it?

Well, I think it depends on the investor I'm speaking to. Some investors like customer concentration because it means big wins and some customers -- sorry, excuse me, investors don't like high concentration. So I won't please everyone. Generally, what do I think? I think that it's getting more complicated to become a 10% customer because we're growing 40% a year, right? So the denominator is getting quite big at a high pace. So I think it's going to become more complicated to clear the 10% goal. But never say never.

We're excited. We have at least 2, where you said that -- maybe 3 to 4 will come in this year. But it will get more difficult. And I think just as we gain share in other areas, the 10% customers, I don't think you're going to see 6% or 7%. If do we float between 2% to 4%. Yes, maybe that lasts for a little while.

Okay. And then just talk to us about purchase commitments, get your perspective on where you are with those and how we should think about it?

Yes. I think a couple of things. One is we're pretty, I would say, prudent, if that's the right word, but we will also lean in with the financials to do things like this. So I'm okay to lean into purchase commitments because I'm very clear why and what is at the end of that and what it means. We have about 2 quarters' visibility. So we're leaning into 2 quarters, and Brendan and I spend a lot of time what do we lean into based on history and what we hear from the customers. So it's educated and informed between the 4 quarters.

But the great thing is with our portfolio. It can serve many customer segments. So we're not over-rotating on purchase commitments that only serve one. If something happened to change, we could use that product across many other customers, especially with the innovation coming. So I feel pretty comfortable with that process and what it means.

Okay. Talking from the audience, I'll just read it. A quick question. Is there any scale up in product deferred yet?

No, we don't even have a scale-up offering yet.

Okay. So I mean you have a lot of cash. You have a lot of cash flow. How do you think about M&A versus buybacks, do you have capability gaps that you'd rather buy than build? What do you think?

Yes. I think generally for capital allocation. So first, I go to Ken, Todd, Andy, Jayshree, what do we need to do organically, okay? We cover that, and that's pretty much in our run rate that you're seeing especially with interest what they're doing, we're getting a lot of good return on marketable securities. So we'll continue to do a bit of that. So now we're down to share buybacks and M&A.

M&A, we're always looking for things that make sense. But the 2 things we want to make sure that it's compatible with all the innovation we do and doesn't break it and fits the culture. And so if we see things there, we don't see any major gaps, Mike, to your question, but we're always looking for great talent and these sorts of things. So if something comes across, we definitely take a look. And so we look at things I would say every month and try to assess if it's something. We just haven't -- we haven't seen anything outside of the Bell Cloud acquisition that we did last year. That's come up, yes.

Nothing's changed in terms of more of a strategy to bring optics more in-house. You haven't spoken about that. That hasn't changed.

I think that nothing's changed. I think we've got a lot to work on with just doing what we plan on doing. So unless Brendan, there's something you want to add, but nothing's changed there.

We actually invented XPO optics and then we essentially open sourced it. There's open MSA with over 100 companies. So that's an example of how we innovated but didn't hoard it and didn't keep it to ourselves. So yes, we're not an optical company.

What's the status of XPO? And is that driving any incremental switch and routing revenues for you yet?

Definitely not yet. XPO is an amazing tech. We've seen a ton of customer interest in it. Like just I just said, over 100 companies that have signed on to build products and be part of the MSA. What XPO is doing for us now is driving a ton of discussions for the longer-term horizon in product planning because XPO solves key problems for customers in terms of density as well as liquid cooling at that density. So it's being built into new product concepts, new product discussions with customers, but it's not part of any sort of revenue or deferred or anything like that you might want to ask.

Okay. And Chantelle, maybe just comment because I haven't asked you and we've got 1 minute left. So on enterprise and campus, kind of the success you're seeing there, the growth rate, the guidance for that part of the business?

Yes. So as quickly, super excited about campus, 5% market share, share gain mode similar to what we did, rinse, repeat, on the data center. So we're all systems go. We've won lots of greenfield new logos just on campus, which tells me that we don't need to be in the data center first, which is great validation and recognition of our product. $800 million last year, $1.25 billion the guide, you can do the math what that 45%, 50% growth. Market is not growing that way. Seeing lots of tailwinds from our competitors, one competitor has a lot of M&A confusion on the road map. The other one has too many operating systems. So we feel really good and this is the steady. So this is just a focus. It's higher volume, lower dollars, so it takes time, but we're excited.

Okay. Well, let's move by. It's really a pleasure to speak with you both. I hope the audience enjoyed it. I enjoyed it, and I look forward to catching up again soon. And thanks to everybody for joining us.

Thank you.

Thanks, Mike. Thanks, everybody.

Welcome to the Second Quarter 2026 Arista Networks Financial Results Earnings Conference Call. [Operator Instructions] As a reminder, this conference is being recorded and will be available for replay from the Investor Relations section on the Arista website following this call.

Mr. Rudolph Araujo, Arista's Head of Investor Advocacy, you may begin.

Thank you, Regina. Good afternoon, everyone, and thank you for joining us.

With me on today's call are Jayshree Ullal, Arista Networks Chairperson and Chief Executive Officer; and Chantelle Breithaupt, Arista's Chief Financial Officer. This afternoon, Arista Networks issued a press release announcing its fiscal second quarter results for the period ending June 30, 2026. If you want a copy of this release, you can find it on our website.

During the course of this conference call, Arista Networks management will make forward-looking statements, including those relating to our financial outlook for the third quarter of the 2026 fiscal year, longer-term business model and financial outlook for 2026 and beyond, our total addressable market and strategy for addressing these market opportunities, including AI, inventory levels and management, lead times, purchase commitments, component supply and product innovation, which are subject to the risks and uncertainties that we discuss in detail in our documents filed with the SEC, specifically in our most recent Form 10-Q and Form 10-K and which could cause actual results to differ materially from those anticipated by these statements. These forward-looking statements apply as of today, and you should not rely on them representing our views in the future. We undertake no obligation to update these statements after this call.

This analysis of our Q2 results and our guidance for Q3 2026 is based on non-GAAP and excludes stock-based compensation expense, intangible asset amortization, gains, losses on strategic investments and the income tax effect of these non-GAAP exclusions, including the recognition of direct excess tax benefits associated with stock-based awards. A full reconciliation of our selected GAAP to non-GAAP results is provided in our earnings release.

With that, I will turn the call over to Jayshree.

Thank you, Rudy, and welcome, everyone, to our second quarter 2026 earnings call. Arista is experiencing significant demand to achieve our first $3 billion quarter in revenue. To put this in perspective, just 5 years ago, our entire year was $2.9 billion in 2021. We have also entered the prestigious Fortune 500 list in '26. And in addition to that, we are now included in the Russell 50.

Our AI fabrics momentum with Etherlink switches now exceeds 100 cumulative customers from the initial 4 to 5 customers I spoke of in 2024. Arista has developed innovative features to enable Smart System Upgrade, SSU; deep analytics, load balancing at scale for AI training workloads.

Our latest member is the 7060XE7 for 100 terabit capacity and 1.6 terabit throughput as well as the first liquid cooling options, highlighting our continued scale-out leadership. Over a decade ago, we pioneered the use of leaf and spine topologies in the data center and cloud networks. We are now building upon that with our lossless and high-performance AI fabrics.

The maximum possible scale for an AI network generally depends on two things: the number of tiers in the network and the number of ports per device, often known as Radix. Increasing the tiers and ports is expensive and power hungry. Our customers deploy and often chose the Arista flagship 7800 AI Spine to achieve that high scale without adding additional tiers.

Scale-Across is an important application. The scarcity of compute capacity, physical space and gigawatts of power mandate that the AI infrastructure must be designed thoughtfully. The Arista 7800 platform continues to be the flagship spine for distributed scale across applications, providing traffic isolation, contextual routing and security. The Scale-Across switching and routing TAM is forecasted to be roughly $15 billion to $20 billion in 2030, and Arista is well poised in this segment.

Our Scale-Across AI innovations deliver programmable and deterministic routing, SRv6 multi-plane forwarding, multi-tenancy and traffic engineering as well as load balancing across the regions. We are capable of providing near instantaneous recovery in the event of transient congestion, packet loss or a physical failure of AI clusters independent of their geographical location. This Scale-Across use case is expected to be approximately 30% of our overall AI target of at least $3.6 billion in 2026.

While compute and AI accelerators supporting billions of parameters often grab the headlines, we did introduce a suite of EOS, Extensible Operating System innovation to enable a robust AI network capable of diverse models and accelerators.

At this point, I'd like to invite Ken Duda, our President and Chief Technology Officer, to highlight some of these AI innovations.

Thanks, Jayshree. Look, I have never witnessed the combination of rapid innovation and scale deployment that we are seeing in AI networks.

I'd like to call your attention to 3 innovations: SSU, MRC and SRv6. First, SSU. SSU is Arista's Smart System Upgrade, the ability to upgrade switch software without any disruption. Frequent upgrades are a hard reality today, especially as AI both uncovers security vulnerabilities and creates tools to exploit them. While many competing systems require a full reboot to address these issues, leading to expensive and disruptive downtime, Arista's EOS handles these upgrades seamlessly. We ensure our customers stay secure without sacrificing even a single minute of valuable XPU cycles.

Second, to maximize XPU utilization, you need MRC or Multipath Reliable Connection. See in first-generation AI networks, every packet on an XPU to XPU flow has to take the same path. That means if 2 flows hash to the same link, they both run at half speed. MRC enables senders to spray a single flow across many paths through the fabric, where receivers reassemble any data that arrives out of order, eliminating the performance hit from fabric hash collisions. But how is the sender supposed to control which paths the flow will use? And that's where the third innovation comes in.

SRv6 or Segment Routing, it's not new, but using it to load balance an AI fabric, that's the game changer. The sender tags each packet with a stack of SRv6 segment IDs, dictating the exact path the packet will take. The system then uses real-time congestion signaling to dynamically shift packets away from hotspots. Because Arista EOS provides a single unified operating system, we support this SRv6 intelligence all the way from the scale-out fabric to the long-distance scale across routing. It gives our customers the combination of high quality, top performance and operational simplicity that Arista is known for.

Thank you, Ken. Undoubtedly, the Arista EOS architecture shines with its inherent state sharing, programmability and single binary. And all of this, as you just pointed out, is foundational for reliable accelerator operation and optimal compute utilization. Arista's multipath and multiplane monitoring with explicit SRv6 probes ensures that reliable performance for accelerator communication. We have collaborated with leading customers to build that AI fabric with that operational excellence.

Well, as you know, during the last 6 months, I've been quite vocal and candid in sharing our supply chain challenges and concerns, not only affecting us, but affecting the entire industry. While the industry-wide supply tightness and rising component costs persist, Arista has taken individual and aggressive proactive steps. Arista is making solid progress here in addressing our tight supply chain. After all, we have a lot of experience that comes from many years. During the lawsuit crisis, we had to build a manufacturing site in the United States in 2016, during COVID challenges in 2021, and here we are back again in 2026.

Our manufacturing rigor is based on a 3-pronged approach. The number one is the people and leadership. Recently, we've hired a terrific global operations executive, Eugenia Corrales with over 35 years of engineering, networking and manufacturing expertise. And she has built an outstanding suite of leaders for new product engineering, contract manufacturing, global supply chain, direct fulfillment and logistics.

We are also partnering closely with our key suppliers to meet our prioritized forecast, and I'm so thankful to them for their continued cooperation. And finally, Arista is leaning in with our increased multiyear purchase commitments, now almost tripling from a year ago at $3.6 billion to approximately $9.7 billion by the end of Q2 2026.

To describe that relentless execution, I would like to invite Todd Nightingale, our Chief Operating Officer and President. Over to you, Todd.

Thanks, Jayshree. Arista has spent the last 6 months, improving our supply chain to meet growing product demand, and we're seeing significant improvements. We've secured multiyear agreements with leading vendors of strategic components, qualified new suppliers in key areas to limit risk and built out supply chains for next-gen AI technologies. Our capacity has been increased in both manufacturing and distribution, and we've negotiated better component delivery terms to drive up both factory efficiency and capital deployment.

Relationships with our strategic silicon vendors continue to be strong with really excellent collaboration in both supply chain and technical engagements. Our memory supply has been secured for 2026, and we have extended visibility well into 2027 across DDR4, DDR5 and NAND memory. And importantly, we've increased our resiliency through optionality and expanded vendor qualification.

For PCBs and optics, we're now able to build capacity in a 12-month window and have strengthened our engagement and commitments from key suppliers. We've improved our lead times and inventory management of thousands of component SKUs, improving subcomponent pipelining and multisourcing and providing increased flexibility with reduced inventory risk.

In a new area, we've now established a liquid cooling supply chain capable of driving and delivering the next generation of AI infrastructure. This includes cold plate, quick disconnect and tubing vendors with capacity agreements for cutting-edge new AI technology. And to match our capacity with customer demand, we've increased both our manufacturing and distribution capacity. We have now 3 contract manufacturers and 3 distribution facilities, providing geographic diversity in the U.S., in Asia and in Mexico.

By focusing on vendor stability and diversity, risk mitigation and predictable delivery terms, innovation for new AI products and capacity across our factories, we are making significant improvements and in significant capacity increases across our supply chain. Thank you, Jayshree.

Thank you, Todd. My God, it's so gratifying to hear the great strides and progress that you have made in such a short time. Great job by you and the team.

Given our improving stance in supply chain, we are excited to increase our guidance for the third time this year to $12.6 billion revenue in 2026. We are now projecting 40% annual growth, which is an incremental $2.1 billion over our Analyst Day goal of $10.5 billion and an incremental $1.1 billion over our recent projections of $11.5 billion in May of 2026.

Our renewed enthusiasm in fulfilling demand in the second half of '26 is expected to apply across all our product sectors in a widespread manner, including the back-end AI fabrics, the core data center front end and campus and routing adjacencies.

And with that exciting guidance, I'd like to turn it over to none other than our Chief Financial Officer, Chantelle, for more financial specifics.

Thank you, Jayshree. It's great to see the supply chain ecosystem gaining traction to meet our customers' demand. Let's review how that is translating into our financial performance and outlook.

To start off, total revenues in Q2 were just over $3 billion, up 37.7% year-over-year and above our guidance of $2.8 billion. This significant growth was driven by our AI and enterprise customers. Congratulations to the employees on our first $3 billion quarter.

International revenues for the quarter came in at $697.8 million or 23% of total revenue, up from 15.5% last quarter. This quarter-over-quarter increase is primarily influenced by strong organic growth across our international regions, combined with a shift in the geographic mix of sales to our large global customers.

The overall gross margin in Q2 was 63.4%, down from 65.6% in the prior year, driven by end customer mix and up from 62.4% in the prior quarter, benefiting from both tariff refunds and customer mix.

Operating expenses for the quarter were $411 million or 13.5% of revenue, up slightly from the last quarter at $396.8 million due to an additional investment in liquid cooling, high Radix switching and AI optimizing software.

Our R&D spending came in strong at $278.1 million or 9.2% of revenue, up slightly from the last quarter at $271.5 million. Arista continues to demonstrate its commitment and focus on networking innovation.

Sales and marketing expense was $109.8 million or 3.6% of revenue, down slightly from 3.8% of revenue last quarter, representative of the highly efficient Arista go-to-market methodology.

Our G&A costs came in at $23.1 million or 0.8% of revenue, up slightly from $21.8 million last quarter, reflecting our strong base cost productivity within a pure-play networking business model.

Our operating income for the quarter was $1.5 billion or 49.9% of revenue, an incredible financial outcome for the company. Other income and expense for the quarter was a favorable $120.3 million, and our effective tax rate was 20.3%. Overall, this resulted in net income for the quarter of $1.3 billion or 42.9% of revenue.

Diluted earnings per share for the quarter was $1.02 based on 1.276 billion diluted shares, representing a significant 39.7% increase from $0.73 in the prior year.

Now turning to the balance sheet. Cash, cash equivalents and marketable securities ended the quarter at approximately $13.3 billion, up from $12.4 billion at the end of Q1. In the quarter, we did not repurchase our common stock. Of the $1.5 billion repurchase program approved in May 2025, $817.9 million remain available for repurchase in future quarters. The actual timing and amount of future repurchases will be dependent on market and business conditions, stock price and other factors.

Now turning to operating cash performance for the second quarter. We generated approximately $1.1 billion of cash from operations. This was driven by a robust earnings performance, coupled with an increase in deferred revenue. DSOs came in at 68 days, up from 64 days in Q1 due to the timing of customer shipments and invoicing. Our inventory turns remained at 1.7 for the quarter. We ended the quarter with $2.5 billion in inventory, up from $2.4 billion last quarter. Inventory level fluctuations are expected to continue as we work through the balancing of component timing and availability. This could result in quarters of elevated inventory balances affecting the timing of cash flow from operations ahead of the deployments.

Our purchase commitments at the end of the quarter were $9.7 billion, up from $8.9 billion at the end of Q1. As mentioned in prior quarters, this expected activity mostly represents purchases for chips related to new products and AI deployments. Our total deferred revenue balance was approximately $6.9 billion, up from $6.2 billion in the prior quarter. The majority of the deferred revenue balance is product related. Our product deferred revenue increased approximately $600 million sequentially versus last quarter.

We remain in a period of ramping our new products, winning new customers and expanding new use cases, including AI. These trends have resulted in increased customer-specific acceptance clauses and an increase in the volatility of our product deferred revenue balances. As mentioned in prior quarters, the deferred balance can move significantly on a quarterly basis, independent of underlying business drivers.

Accounts payable days were 57 days, up from 54 days in Q1, reflecting the timing of inventory receipts and payments. Capital expenditures for the quarter were $29.7 million. Our construction work to build expanded facilities in Santa Clara remains on track, and we expect construction to be completed by the end of fiscal 2026.

These exceptional Q2 results, combined with the ability of the ecosystem to deliver what is required, are foundational to underpin our financial outlook for the company. Reflecting our strong momentum, we are raising our 2026 fiscal year outlook to 40% revenue growth, equating to approximately $12.6 billion. Within this guide, our 2026 campus revenue goal is at least $1.25 billion and our AI fabrics goal is at least $3.5 billion.

For gross margin, we are maintaining the range for the fiscal year of 62% to 64%, inclusive of mix and anticipated supply chain cost increases for memory and silicon. We have increased our fiscal 2026 operating margin target now at a range of 48% to 49%, while maintaining an expected tax rate of 21.5%.

Now more specifically, our guidance for the third quarter is as follows: revenues of approximately $3.3 billion, gross margin of approximately 63%, operating margin between 48% and 49%, diluted earnings per share between $1.06 and $1.08 with approximately 1.279 billion diluted shares. Our effective tax rate is expected to be approximately 21.5%.

In closing, the Arista team is energized. We are well positioned for this AI super cycle and for Ethernet networking overall. This is earned through a combination of our innovation, our culture and our focus. The opportunity ahead of us is tremendous, and we are ready to capture it.

Now back to you, Rudy, for Q&A.

Thank you, Chantelle. We will now move to the Q&A portion of the Arista earnings call. [Operator Instructions] Thank you for your understanding. Regina, please take it away.

[Operator Instructions] Our first question will come from the line of Amit Daryanani with Evercore.

Congrats on a really good set of numbers here. Jayshree, maybe I'll just ask you the opposite of the white box question you typically get. One of the trends we hear a lot from hyperscalers and even frontier labs is that the AI networking is becoming a lot more complex in multiple dimensions simultaneously. You not only have denser clusters, but also you need to connect campuses and multiple data centers.

As the networking problem seems to be getting more complicated, more system level, does that increase the value of an integrated networking platform versus white box approaches? And then are you seeing customers rethink the build versus buy decision at this point when it comes to AI infrastructure, both across hyperscalers and frontier labs?

Well, thank you, Amit, for the good wishes as well.

I think you're absolutely right that Arista's networking strategy has accelerated. And as you know, there's 3 types of AI fabrics that are critical for us to participate in, scale-up, scale-out, and scale-across. Especially in scale-out and scale-across, I think the importance of the supply chain and rapidly being able to connect their processors so they don't remain idle and the ability to get consistent performance because they often cannot get the power in one location. So they have to distribute and get the same level of capability, security, traffic engineering is becoming critical.

So I would say white box is certainly a tactical solution that we tend to see more in use cases that are simple, scale-up or scale-out where the actual amount of software and system requirements are low. But when you look at traditional network topologies, you can slow down the job completion significantly if you go with a box-by-box approach. And so this -- as you rightly point out, the Etherlink system-wide portfolio with all of the features Ken alluded to for reliability, MRC, SRv6, traffic engineering, synchronizing elephant flows, low latency, this massive training and inference does put more pressure on the combination of our hardware and software, and we feel very well recognized and ready to achieve that.

Our next question will come from the line of David Vogt with UBS.

Maybe just one question. So Jayshree, you took up the calendar year '26 revenue guidance substantially from last quarter. But if I remember correctly, you got the AI target unchanged and only touch the campus. Can you kind of explain kind of the thought process there? What are you seeing from other customers and other verticals and other use cases that sort of ultimately result in sort of that algorithm that you just laid out going into the balance of calendar '26?

Yes. No, if you had to ask me whether our AI number or campus number will go up, I think Chantelle, Todd, Ken and I absolutely believe it will. The question is not whether it will go up. The question is what is that number?

And that I would like to reserve that $1.1 billion question to, well, it depends on how we ship. If we ship more front-end AI or we ship more WiFi or wired or Etherlink switches or routing. So I'd like to give our customers the priority and Todd's team the flexibility to ship what we can. And that's why we're not holding ourselves to a number. But I think at this point, we can most certainly say all numbers are going up.

Our next question comes from the line of Michael Ng with Goldman Sachs.

Maybe I'll ask about the supply chain improvements. Last quarter, you talked about a supplier that was decommitted upstream. Maybe you can just expand a little bit on some of the efforts this quarter. I think you talked a little bit about a vendor qualification expansion in memory, strength in commitments from key suppliers. Are they getting more capacity? Are you offering more pricing on your side? Are you getting more customer advocacy? Any thoughts on there?

Absolutely, Michael. So listen, I don't want you to believe that suddenly, we waved the magic wand and all our problems have gone away. The industry is going to have a 2-year problem. I don't think we get out of it as an industry until 2028. But Arista is taking individually and specifically steps in the first half of this year that we believe will have results in the back half of this year. Over to you, Todd.

Yes. On the silicon side, we have very, very tight relationships with our silicon vendors, and that goes to both how we work through all the supply chain and how we've improved the delivery on those components, but also the technical engagements for new platforms that are super exciting to get into the field. Both have been going very well.

As far as memory or I would just say memory, PCB optics, et cetera, we've been able to work pretty hard at adding optionality, qualifying new vendors very quickly through our engineering teams, and that helps us bring multiple paths to delivery possible through the supply chain.

We've also worked very hard, especially in the last 6 months to improve our terms, and that means having shorter lead times and being more nimble. So if our demand shifts from 1 SKU to another, we're carrying less risk. We're able to be more nimble, and that's been incredibly successful, especially in the last 6 months.

Our next question will come from the line of George Notter with Wolfe Research.

My question was just on the bigger picture view on all these technology changes going on in the marketplace, CPO, NPO, XPO. Obviously, customers are building next-generation racks and switch platforms. And I guess I'm just trying to understand how you see that mix of technologies changing going forward? And how does that benefit Arista or hurt Arista? Like what's the bigger picture perspective on what you guys are seeing longer term?

Yes. George, first of all, I think it depends on the use case. Let me take the scale-up use case, which we are less prevalent in.

I think there's very much a philosophy there on copper if you can, optics if you must. So I think you're going to see a lot of copper in that 2-meter, 3-meter distance, well within a rack, that type of thing and the importance of pluggable optics. But in some cases, there is a number of instances of proprietary implementations of traditional co-packaged optics that's been floating around. Arista is not a fan of 5 different proprietary implementations. They're going to have and we're going to commit and Andy and the team have been working hard at this to really solve one, which is an open CPO.

And we don't think open CPO is going to happen overnight. But the idea here is to use socketed optical engines, pigtail fibers and allow these modules to be fully pretested. And whether they started on the board or nearby, the idea is to have a truly open interface that can operate with multiple vendors and multiple switch configurations. And sometimes those open CPOs are often called NPO too, [ nearby ] optics, right?

So we're big fans of that. It's very early stages. It probably comes into examples and trials next year. And probably from our perspective and the industry perspective with all the supply chain shortages, majority of the world will still remain pluggable optics and copper, but there will be some amount of co-packaged optics in 2028 and 2029. So that's how we kind of see the world.

Our next question will come from the line of Ben Reitzes with Melius Research.

Great quarter, Jayshree. I actually did something weird I read the press release, and there's a line at the end that you're going to host a webinar with Anthropic and Palo Alto. So it got me thinking -- can you just talk about your progress in landing the AI labs as customers and how things are developing with that potential 10% plus customer in the fourth quarter?

You're sneaking in more than one question there, but thank you for reading the press release. And I think the mythos and the vulnerabilities is very front and center. And first, I just want to acknowledge Ken's architectural design of EOS and how we have the lowest vulnerabilities and we're absolutely committed to building that rock-solid foundation.

But to make AI secure isn't just our responsibility. It really comes across the board. We need to work with the leading model providers. We need to build a robust infrastructure, and we need to work with the best security vendors. So we thought nothing better than getting the best-of-breed network model and security providers to do this together because vulnerabilities are a fact of life, but how we proactively deal with them with the right technology, with the right systems and the right process is exactly what that does. And I think it's September 8 tune in for that because I sure won't do justice to that in this call, but it's very important.

In terms of our own approach to models, every day, it's in the news, there's a China model, whether it's a DeepSeek or whatever. But from our standpoint, the network must be robust no matter what the model. There's going to be a lot of enterprise AI agents. There's going to be a lot of diversity of models. It's going to be training at some point, but it's going to move to inference.

Arista just taking a lot of care to make sure that we build that multi-model network that can handle all of the traffic and all of the different priorities and SKUs. So undoubtedly, as you can understand, some of the work that Ken and the team did on MRC sometimes requires us to do work on the network, but sometimes requires us to deal with the packet spraying and how the end host behaves.

Ken, do you want to say a few words on that with MRC?

Yes. I mean, look, we are extremely excited about the growth and diversity in the industry. The more diversity there is among models and model makers and between AI infrastructure providers, the better for us. And we've been a best-of-breed player from the very beginning, and we continue that tradition as we expand into AI networks. And MRC is one example of that of UEC work we've done also is another example of Arista strongly supporting the industry's growth and enabling the best-of-breed solutions through open and interoperable standards.

Our next question will come from the line of Aaron Rakers with Wells Fargo.

Congrats on the quarter. Kind of building a little bit on Ben's question there. Given all the supply chain work that you've done and the improvements on lead times and such, Jayshree, maybe can you revisit your thoughts on adding a 10%? I think in the past, you've talked about 1 or maybe even 2 additional 10% plus customers. And in that, does the 2 Ms remain 10% plus customers as we think about the updated guide for 2026?

I can't escape that question. Okay, Aaron. Well, thank you for the wishes. I'll bask in that glory for 2 seconds.

But look, we're going to increase the number by $1 billion or more. And undoubtedly, we remain very committed to our 2 longest partners, Microsoft and Meta. And I fully expect there to be 1, maybe 2 10% customers. I'll leave it at that just because we want all the flexibility on what's in the product sectors and who are the 10% customers as we ship. So I want to give Todd the ability to ship lots and lots of products.

Our next question will come from the line of Karl Ackerman with BNP Paribas.

Jayshree, could you address the growing partnerships you have with Neoclouds adopting custom XPUs? In particular, do you believe there are growing alternatives to NVLink and optical circuit switches for scale-up that you can address over time? How are you feeling about your relative opportunity in scale-up switches versus earlier this year?

Karl, thank you. That's a loaded question. So let me kind of parse it as much as I can.

So first, we live in an NVIDIA world. And I think we all can safely say it's a high percentage of the GPUs we connect to. So there's really 2 use cases there. One is where NVIDIA provides the full vertical stack and usually, that's an NVLink. So there's very little participation from Arista or anybody else's scale up. And generally, it Arista does better there in the scale-out or scale-across domain.

The second is the non-NVIDIA accelerators, and you've heard me talk about our enthusiasm with the MI series from AMD. We're excited about the Google TPUs. Increasingly, we see that as a formidable training processor. And we're very excited about the range of inference accelerators as well. And we have a number of partners who are working with -- you can imagine, many of our customers are building their own in-house.

So now parsing your question a little bit. In that sector, where it's non-NVIDIA, Arista will be excited and will be working more closely, both in the scale-up and scale-out, in some cases, to build custom racks with their custom processors so that we can better tune our network with the behavior for their inference or training engine.

In the NVIDIA cases, it's going to take a bit longer. I feel a little bit like 2, 3 years ago when we were talking about InfiniBand and now we don't mention InfiniBand, but it took 2, 3 years to move to Ethernet. So it will take time to go from a proprietary scale-up that's been around a long time with NVLink to these other alternatives, even if Ethernet is really good. But I expect us to do much better there.

Our next question will come from the line of James Fish with Piper Sandler.

Just on the 1.6, I guess, how many customers are currently qualifying or deploying that now that it's become out there in the market? And are you guys still thinking about that as production scale next year and a growth driver for that point?

And then just secondly, Chantelle, on the annual guide, you did raise the core to an acceleration now. Is there a way to think about how you guys are seeing the upgrade and refresh cycle impact your business versus kind of drag along between front and back end?

Great. On the 1.6T, if I -- I'll go back, history is always a great lesson for what will happen. If I look at the 800 T, we were in trials in '23, '24 and the real ramp came to us in '25 and '26. So it takes about 6 months, maybe even a year sometimes. And in this case, I think it will definitely take a half a year to get to production with the advent of liquid cooling and all the infrastructure the customer has to put in. So we will be in trials in the second half of this year. In terms of customers, it will be single digits, but very large customers. And I think the real production will still be in 2027.

And you were asking Chantelle a question on refresh. Over to you, Chantelle.

Yes. Thank you. Thank you. Yes. I think, James, nice to hear from you. I think from the piece that is in campus and that isn't the AI, the -- in between goal that you're referring to, we are pretty excited. It will come down to that $1.1 billion raise like how that gets divided out.

But where are we excited? We're super excited by the new logo acquisition. We're very excited about what we're seeing on international growth. We're excited on the land and expand that we're seeing going both from campus to data center and data center to campus. So there's a lot there to be working through, and we'll see how much we get to through the end of the year.

Yes. I was hoping Karl would be here, and we can tell them we're excited about the front-end data center and the enterprise is doing really well. But Karl, this one is for you. This answer from Chantelle.

Our next question will come from the line of Matt Niknam with Truist.

Congrats from my end on the quarter as well. A question on gross margin. So they improved about 100 bps sequentially despite some higher costs. So a, maybe Chantelle, can you help us think about the tariff refund benefit in the quarter? And then just sequentially, was the lift more mix related? Or was there any sort of pricing relief that's flowing through to offset some of the higher costs?

Yes, it's a great question. I would say the kind of the -- I think versus guide is probably the best way to do it versus guide, you'll see there's probably 20 to 30 bps of tariff refund and the remainder more of a mix equation. So I would put that 20 to 30 for the quarter versus the guide. Probably in the range of maybe 30 to 40 bps if you look versus prior year, but it's in that kind of range. And the rest will be customer mix oriented. I wouldn't put anything in there yet due to a price increase in that equation.

No. As we said before, the price increases will really help or affect us only towards the end of the year or more like next year because we're still going through a lot of backlog sales.

Our next question will come from the line of Simon Leopold with Raymond James.

I think Tal is a software analyst these days. So he left us. Anyway, I wanted to follow up on the incremental $1 billion for the year. In that, I think you've reiterated the campus and AI. So I'd like to try to get a better understanding of the composition or the source of the incremental revenue if it's not the AI or campus portion?

Okay. Actually, that's a great question, Simon, because in a nutshell, the answer is this is our core Arista product line we're talking about. Campus and AI are the newcomers to it. So if you take out the campus and AI, which we believe will grow, then one of the things that our new software analysts tell us and questioning me on is why is your core data center front end so flat.

And so I'd like to first make the observation that it isn't going to be flat, but we couldn't answer that question in Q1. We needed to go through the quarters to understand how the demand would translate into shipments.

So we fully expect some growth in the front end and core data center, the enterprise team, and I just want to give a shout out to Chris Schmidt and Ashwin, the campus team, I want to give a shout out to Kumar. They have been on record ground, and they've been growing tremendously well. So I expect great contributions from the enterprise into that incremental $1.1 billion number in addition to AI.

And likewise, with routing, routing is an adjacency, both for edge routing use cases, but also some of the DCI and scale-across. This is an incredibly large TAM and getting larger. So we expect that $1.1 billion to consist of all our product sectors, and we'll know exactly what it is once we ship it.

Our next question will come from the line of Ryan Koontz with Needham.

It's Jeff Hopson on for Ryan. I was just curious of kind of where we are with the scale-across build-outs. Like is it concentrated to maybe a couple of the cloud titans? Or can we see a world where this extends out to some of the Neocloud customers as well?

Yes. That's a good question, Jeff. We definitely see the -- why is scale-across such a big thing? I was talking to one of the industry luminaries and he goes, well, this will be temporary because once people get capacity of compute and power, they'll go back. And the answer is no, they won't because we're going to be in a constant state of scarcity for power, space and compute. Getting all those 3 to lock in, whether you're a cloud titan, an AI titan or a Neocloud is going to be very, very difficult.

So currently, our scale-across is dominated by the cloud and AI titans. But I see no reason why it wouldn't apply to -- and we're already seeing it apply to several Neoclouds. So I would say less in the enterprise and definitely more in the Neoclouds and titans.

Our next question will come from the line of Antoine Chkaiban with New Street Research.

Maybe a quick follow-up actually on the scale-across. So like how large is the overall opportunity today relative to the $1.2 billion, like the 30% of the $3.6 billion that you referred to? And how much do you think you can capture of the $15 billion to $20 billion in 2030, given like all the color that you gave on SRv6 and the value it delivers when customers like Arista or both scale-out, scale-across?

Yes. Antoine, the market research is suggesting this -- I'm going to work backwards to answer your question. The market research is suggesting that it's going to be about a $15 billion, if you add some of the optics, maybe $20 billion in 2030. So I would say in 2026, as we capture $1.2 billion, this market is still maybe $3 billion to $4 billion, but quickly going to $15 billion in the next 4 years.

Our next question will come from the line of Meta Marshall with Morgan Stanley.

Jayshree, you've talked in the past about kind of new customers who have come in who have maybe wanted to start down the road of blue box and then discovered with the complexity that they actually need to go down the road of EOS. Can you just talk about kind of the latest trends that you're seeing there, particularly as you continue to add customers?

Yes. Good question, Meta. We continue to see the importance of blue box because of, I would say, 3 things, and then I'll tell you the counter view on why a white box may still be useful.

The 3 things they value greatly with EOS is operational excellence. They don't have to put a lot of staff. Most of these Neoclouds don't have staff. And even if they're paying a little more for the CapEx, it more than makes up for the operating cost that they would incur. So that's a huge piece.

The second is the AI features themselves. You heard Ken talk about a few of them. There's a tremendous depth and breadth to EOS that they can't recreate in a white box or they can figure out how it is. And the third is reliability and vulnerability, which is becoming top and center. You can't put these things in the middle and have them blow up.

So -- and our combination of both EOS and NetDL, our diagnostics layer, which plays in both the hardware and software has been very compelling. So we continue to see that while it's interesting to talk about these open NOSes that more and more customers want either EOS itself in its entirety or a hybrid combination of open NOSes and EOS.

Now that doesn't mean it's everywhere. If somebody wants to just go put in commodity hardware and get the ultra-low price, such a market exists in every large market. And it's not -- it's there in campus, it's there in data center, and it will be there in AI, too. So there are customers who will just prefer to go with the white box because it's ultra cheap or that have large amounts of staff like the titans often do, and they can manage it and deal with it and they're built with it.

But having said that, I think in this in this current scarcity of supply chain and people and needing to deploy AI fast, Arista is really winning out with the system-wide approach on EOS and good hardware.

Regina, we have time for one last question.

Our final question will come from the line of Atif Malik with Citi.

It's Adrienne for [indiscernible] with the tightness in the overall supply environment and your demand that you're seeing, I'm wondering how far out your visibility with customers is extending?

Adrienne, hope you're doing well. I think with the -- we still have the same kind of 2 quarters of visibility that we referred to. But what we would say is given where we are at this time of year, Jayshree and I are guiding based on what we're confident we can get the supply for. And if the supply was to release a little more, there is an opportunity to do better in the year. So we'll have to wait and see.

This concludes Arista Networks second quarter 2026 earnings call. We have posted a presentation that provides additional information on our results, which you can access on the Investors section of our website. Thank you for joining us today and for your interest in Arista.

Thank you for joining, ladies and gentlemen. This concludes today's call, and you may now disconnect.

Welcome to the second day of our conference. Hopefully, you had a great breakfast. Today, I'm very pleased to host -- and I'm not saying it's just to say, but I'm -- really mean it, I'm -- the most favorite CEO in my universe. And she -- we sometimes argue, but it's always coming with a lot of respect to one another. So thank you, Jayshree.

So Jayshree Ullal, CEO of Arista; and Todd Nightingale, COO of Arista. And I've known Todd for many years from his days at Cisco and then Fastly that I took public and now at Arista.

So we're going to have a discussion for about 45 minutes. I'll try to keep it tight for about 40 minutes or 35 minutes and let you ask questions if you have any questions. And the discussion, it's -- as you know me, I'm not a quarter guy. It's not about the quarter. The discussion is really the value of Arista, the sustainability of trends. We do have a spending cycle in the industry with hyperscalers. And through the spending cycle, there are changes to the architecture. There are changes to the network. Customers are deploying certain technologies, and we want to go into it. So the purpose of this session is really to understand the core value of Arista.

And with that, so, last quarter, you raised the full year guidance from 25% to 28%. And I remember when we looked at your guidance, I'm talking about like a year ago, when you look at your guidance, and I told investors, these numbers don't make sense. They're too low. The industry is growing faster. The company, if you take out this and you look at this, it's supposed to grow faster.

So the question is what drives the growth? And I know this is kind of a soft question to start our discussion. What drives the growth right now? And how sustainable is what we are seeing in the past few quarters?

Well, first of all, Tal, you're my favorite too. There's not too many investors who we can say I know for decades. So that kind of times both of us a little bit. And if I start talking about mainframes, it will really time me a little.

But coming back to the growth vectors for Arista, as you know, Arista really made networking sexy again. And part of that was focusing on those growth vectors. We pioneered the leaf-spine architecture, and we really redefined or reimagined networking for the cloud, right? And as you know, we power some of the world's largest cloud titans, as we call it, with this leaf-spine architecture that was different than the standard blocking loss-oriented enterprise architecture.

So today, one of our growth vectors continues to be the cloud customers. But a lot of our growth in the last decade came from what I call the front-end network, the more visible network where we were connecting to compute, storage, WAN, building the active-active leaf-spine, et cetera. In the last 3 years, we really had to study the back end of the network that was historically built through proprietary technologies like InfiniBand. And the first thing we set to work on was really defining Ethernet for those use cases. We now call it AI Fabric, scale up, scale out, scale across, scale up within a rack, scale out between racks and scale across between data centers themselves. And that's really going to drive a huge part of our growth.

Now with me is, of course, Todd Nightingale, our President and COO. And you know he reimagined the campus and enterprise in some of his prior assignments. But I think there's another one coming there as well. So that will be a huge vector of growth for us, where post-COVID, the campus looks very different from the carpeted buildings and you really need a uniform experience client-to-branch everywhere. So I think the AI and campus are going to be our fastest-growing segments. That doesn't mean the others don't grow, but they grow slower.

Yes. And when we look at hyperscaler spending, it's up giant this year, was up giant last year. When you talk about -- when you talk to them about their build-out plans and how sustainable is the cycle? What needs to happen for the cycle not to be just 1 or 2 years or 3 years, but rather a long-term cycle?

Yes. This is a really good question because even I get scared, I look back at our '99, 2000, that was a short-lived cycle. As we all know, it started out the great burst of Y2K and then collapsed. I think the biggest difference here is there is a very sustainable advantage for AI, both networking for AI and AI for networking. So it's going to traverse not just the hyperscalers but go into the Neocloud and enterprises as well. That's one.

And we haven't yet seen all the killer agentic AI applications yet, that's just beginning. So I think this is a multiyear, in fact, a multi-decade cycle. Now having said that, some of this CapEx is just stunning to me. We never thought of CapEx in the trillions, let alone billions back when we started this. So it's important to understand, though, that the CapEx has many, many pieces to it. The biggest one being compute, power and obviously, all the real estate itself, the cooling, the chilling, the buildings, et cetera.

Networking is a small piece of it. But becoming a very strategic piece, meaning I can't let these compute nodes idle. And this is where we really come in because in the past, you could have a bit of underutilization, over utilization, over subscription, it didn't matter. Here, these idle CPU cycles is idle money, right? So the ability to -- for this CapEx to continue growing, I think is high just because -- it's not only the large hyperscalers. There's a force multiplier of others coming into it with the Neocloud and enterprises. I think it's sustainable as far as I can see, which is generally not more than 2, 3 years. But I think this is a transformation much like the industrial revolution or the Internet revolution.

Now, will it have its values and peaks and highs and lows? Of course, Newton's laws of gravity means nothing just goes up to the right, there will be some ups and downs. But overall, it will still go up and to the right.

When it comes to your position, the market is expanding, meaning we started with 4 hyperscalers then Oracle, then Neocloud, now a lot more second-tier cloud. Talk about your position, market share, but not the numbers, rather your position as the market expands to other areas outside of the big hyperscalers.

Yes. And so I think, first of all, if you look back at 2022, our AI position was outside looking in. We were seeing all these GPUs built by NVIDIA connected largely by InfiniBand. So it was -- our position was 0. But interesting thing even back then is customers were asking us for our thought leadership because they were building these proprietary back ends. So today, I would say 3 or 4 years later, our position with the top titans, hyperscalers or even some of the Tier 2 cloud providers is medium to high. There's still existing networks to deal with. But you've heard me often talk about 4 out of 4 or in the past, plus 4 out of 5. We now have production, we went from trials to pilots to production in all these 4 major ones.

Now having said that, there's a whole lot more to do there now because largely, we were looking at production networks that are scale out, connecting all of these scale-up technologies. Now we have the opportunity to not only expand scale out, particularly with the advent of OpenAI defining multi-plane technologies with MRC, but also to scale across because more and more power is a real issue. And I think this is going to be -- it used to be a niche DCI data center interconnect use case, but the power of routing, multi-tenancy, SRv6 and tunneling across this, encryption, working with coherent optics, is going to expand how we build those scale-out network -- scale across networks.

And then scale up is a new market for us, largely today deployed by PCI Express and NVLink switching. But with the Ethernet for scale-up networking ESUN coming out as a spec this year, I think you're going to see a lot more action on that within rack as well. Much more hardware intensive, much more latency, much more defined for high-speed training as well as inference, job completion time, time to first token is all important over there. So this market is multiplying to multiple use cases and is, frankly, redefining the data center as we knew it.

Right. When we think about -- by the way, Todd, I'll get -- I have some questions for you.

Oh, yes, he will get your day in the sun.

Take your time.

I want to first finish the hyperscalers and then we'll get to the important stuff.

Then we will go to [ the enterprise ] campus.

When we look at the hyperscale environment, over the last few years, there was white boxes penetrated to the market. So some companies started with it, Amazon and then Google and even existing customers migrated and expanded the use of white boxes. But as the market goes up to scale up and scale across, talk about your position in this market versus white boxes. And does it mean that your -- if the market -- again, I'm thinking about it conceptually, not about numbers. If the market shrank in the last few years because of white box competition, is the market going to expand again for you now with scale across?

I think the market never shrank by the way. Our total available market has gone from $50 billion to $105 billion is our stated number now. I think by 2030, it will be $150 billion. So there's no shrinking in our market. In the market, there's always segmentation. And anybody build their own PC these days, anybody build their own iPhone these days. Great. You are the candidates for a white box. If you're going to look to build something ultra cheap, don't need a lot of features, white -- we have always coexisted with white box. We will continue to because there's a sort of cost-effective do-it-yourself mindset that will require that.

Now with AI, it's actually scary because you don't want all your AI traffic to be going through across something you do yourself. So we're actually seeing less white box in AI installations and more branded vendors like Arista, like NVIDIA. But that doesn't mean it doesn't exist. It does exist when a hyperscaler customer is jointly trying to develop something at the scale-up level and design their own board and almost virtually give it to a CM who can build it like a white box. So it ends up being a joint engineering, not so much do-it-yourself, but manufacture it with the CM type of mindset. So that's going to continue to exist.

Low software, high hardware, highly defined, different margin profile, typically 20% to 30%, so low software content, we've always coexisted with that. It's been with us -- I mean, I can remember the IPO, when we were $2 billion, $3 billion in market cap 2014, where the first question would be, how are you going to compete against the white box? And as you know, we've coexisted and not only competed, but in many cases, they've chosen us over.

There is a new concept that's emerging for us called the blue box, which is hardware building very, very reliable, high signal integrity, hardware is a nontrivial effort. So what we are seeing now actually is the resurgence of a blue box where more and more customers are not only requiring Arista for the high-level software but for the low-level software, we're building a lot of diagnostics at the power supply level, counters, active components, passive components. This is what we've done for the last 10, 15 years because we have fantastic partners in Broadcom and other switch suppliers. They built great chips, but we build the software to twiddle their chips. And so we literally removed the software development kit of our chip vendors and put in our own network diagnostics and platform level software. And so we think a blue box, which is basically a white box, better designed for mission-critical applications will also factor in and is factoring in already.

Got it. I have many more questions for you, but I don't want him to be bored. Todd, you joined recently, what's your mission statement? What are you focusing on? I mean recently.

I am almost a year in.

I know. I know recently in Arista...

He doesn't like it when I call him a newbie.

When you look at the tenure of the length of position of the other managers, you are recent.

That's true, I am an infant on our team. I think, really, my mission comes in twofold. I mean, one is to ensure that the operations at Arista are smooth that we're always able to deliver to the customers that need it and supply everything worldwide. The second, and I think maybe what's most important when we talk about driving growth is fundamentally bringing the mission-critical differentiation that Arista has to every network. We spend a lot of time talking about the hyperscalers, and that's an incredibly important part of our business. But Arista has always stood for mission-critical networks, the most reliable, most available networks in the world.

And 5 years ago, even 10 years ago, when we spent a lot of time talking about it, there was a divide between people who needed mission-critical and the nice-to-have networks. I don't think that exists anymore. Everyone, every network, every enterprise network is mission-critical right now, and my goal is really to bring Arista to every enterprise.

And how do you make the campus business grow bigger? What are the challenges in campus that you don't see in enterprise data centers -- data center enterprise? What do you need to do in order to make it, as Jayshree said, like a giant business, a big business in the future?

Yes. So I think the first is that the breadth of the portfolio goes far beyond switching. It's why we've spent so much time investing in the rest of the network. 7 years ago, Arista invested heavily in the PoE switching and launching our campus network. That was fast-followed by WiFi. And then just recently, in fact, the day I joined, Arista acquired Velo. And that brought in kind of the missing piece with the SD-WAN technology which really completed the portfolio. Then we had enterprise routing, switching, both spine and leaf, all of the WiFi and now SD-WAN to really attack the branch. That's the first.

And bringing that portfolio into the Arista world and really delivering with differentiated quality the way we always do, that is the mission we're on right now. In fact, we've got the leadership here who's driving that.

I think the second piece is looking at the universe of customers. The data center enterprise data center and hyperscale data center, the amount of customers that make up the big chunk of that market are relatively small, maybe like the Global 2000, et cetera. But campus networks span a much larger group. And we are working very hard right now to evolve the go-to-market to be able to reach all of that TAM, not just in the U.S. but around the world. And that expansion to the whole market sort of go-to-market effort is key.

So elaborate on this, what do you need to do with the go-to-market in order to address the broader market?

Yes. I think one really interesting piece is the thought leadership. And we've seen this -- I've seen this even in my one year at Arista exploding the amount that we see Arista being sort of publicly part of the conversation. And in campus, especially, this has been a huge focus, including the exposure that we need from experts around the industry just a couple of weeks ago, the most recent Gartner Magic Quadrant came out and for the first time, Arista was in that leaders' quadrant, which has opened up already so many doors because people, of course, look at the leader quadrant there and look to...

I just want to take a moment to congratulate, it took us 7 years to get there. We went from being a niche vendor to a visionary and finally, the leadership. And by the way, we're the youngest kid there. Everybody else has been around 25 to 40 years. We entered the market over 5 years ago, right? So congratulations.

There's a great graph that shows the trajectory year-over-year.

So the question is what's your value proposition, meaning what do you bring? What do you -- how do you disrupt the market? What do you bring to the market that is different than what the others are offering?

Before he answers that can I tell a story about that?

Yes.

Okay. And then you'll know the value proposition answer. So about 7 years ago, we were in a room like this with 100 customers, most of them were data center customers. And I said, "How many of you think we should get into the campus?" And 30% of them raised their hand and said, "We are tired of all this other software, spaghetti OSs. We want the uniformity. We want what you brought to the data set into the enterprise." But I said, "What about the other 70% of you?" They go, oh, no, no, we don't want that because you'll get distracted and you won't give me a good experience in the data center or AI or whatever, right?

Fast forward 2 years later, they were like, "Where are your campus products? You're late." So there was a burning desire to bring the same stability, availability, reliability, analytics, automation, software-defined capabilities into the campus that we brought to the data center.

Over to you on the differentiators.

Yes. Of course...

You have a great CEO. She articulated her message so well.

We are in a world right now where the entire industry is focused on exactly how quickly they can execute security patches across their portfolio. And with every other vendor, they're looking at 5 or 6 or 8 different OSs, different packs of software that have to be patched and upgraded, et cetera. And Arista, it's one. And the...

Can I tell another story on that? So when the Glasswing project happened and there were 10 vendors invited in, little Arista wasn't in that 10 vendors. It was Microsoft, Anthropic, Google, JPMorgan, Bank of America. I'm sure, were in there. And everybody said, "Where is Arista?" Because they were expecting us because this vendor, again, has the least vulnerabilities and the most robust operating system to be there guiding them. So we didn't ask to be invited, we were pulled in literally to help solve an industry-wide problem. And that kind of tells our role in this, the silent network, I guess.

And it's a moment in time when every IT shop is staring down this enormous challenge with other vendors, 5, 10 different versions. At Arista, it's one. And that's enormously powerful, demonstrating the value of quality and reliability and not just the availability of their apps and their client connectivity, but how we got there through this diligence, year after year, decades after decades of sticking to this core strategy.

The second piece beyond just reliability is looking at sort of the future of how AI and agents are going to manage these networks. And EOS has incredibly, incredibly powerful data platform. In fact, it turns the whole network into a single observability fabric with complete state streaming, every single stage change across the entire network being fed into our cloud, which means that our AI agents are built on the best possible platform. And that is already being seen by users. And that differentiation heads, years and decades of future ahead of it. And it's really built on the shoulders of giants. It's the state streaming, it's the analytics that are used by hyperscalers that they are used by the biggest data centers in the world being brought into the campus space is awesome, and the response is already great.

So a question for both that was referenced on the last conference call, you spoke about decommits of supply chains and...

It's a word that haunts me now. I actually went and looked it up with the dictionary to make sure I got it right. And just for terminology, when Todd is running this worldwide manufacturing organization, and he puts in a request with silicon suppliers optic CPU memory, often 52 weeks ahead of schedule. This is why you see our purchase commitments now at $8.9 billion. There's usually a promise date they give us, just like we give a promise date to our customer. So the definition of a decommit or recommit is when that date moves. And so we've had a lot of dates move. And that's disconcerting because when their date moves, our date moves to our customers, right? And then it changes the lead time.

So nobody in the industry can tell you that they don't have this problem for if they do, they're an ostrich in the sand, and they're not admitting this a problem.

Second thing I would say is, this is a 2-year industry problem. I'm not saying it's a 2-year Arista problem. I'm saying it's a -- at least 2-year industry problem. And those that are stronger and can plan better and do things ahead of time are the winners. Obviously, we're going to not sit for 2 years and feel bad about the situation. We're actively acting on it. The memory situation was horrendous last November. We've gotten ahead of it. We are paying top dollar. It's going to affect some of our margins while we still stay in the band of 62% to 64% gross margin like we've advertised, but we dealt with it. So we will deal with it, and we will come out of it just like we did COVID, the lawsuit, or this one. But it's no fun for the industry and in my view, the strong will get stronger.

I'll just add, there's surging demand right now. And we see from our customer base upside and upside and upside on the forecast. And that means we have to push on the supply chain to be able to serve that, to be able to drive material needed. And this industry phenomenon. It's just how much upside can we deliver on? I mean it's putting pressure on it, for sure.

So 2 years ago, 1 year ago, we spoke about memory, memory supply constraints. What's the situation of supply constraints now? Did it expand to other areas? What other areas? Like talk about the environment and what is the gating factor for you to grow faster?

Let's just talk -- let's just get the time frame. That memory situation was like 4 months ago. Things are moving quick -- things are moving quickly. And it's going to be across the technology space. I mean we see these capital budgets coming down the pipe that are enormous. People are building out massive, massive data center capabilities around the world. It's not just memory. It's going to be in the wafers and silicon, not just in the high-end silicon. We see it in power ICs. We see compute and CPUs. We started to see surging demand on the CPU as well as the GPU side. A lot of these roads lead back to the same advanced-process fabs. In Taiwan, there's only really one vendor there. And so we are -- when roads lead back to TSMC, there's going to be capacity constraints.

And I think even there, the shortages are really not just at the wafer level, but at the substrate level. Because what's happening is the material shortages here is as you start to build more complex processes with chip-on-wafer then you got to build fab capacity for 2-nanometer, 3, 5, 7, but we still have all the processes that we need to address, right? So it's sort of an across-the-board material shortage that pops up like a game of whack-a-mole. First it's memory then it's -- like you said, optics, CPUs, PCBs, you name it. And holistically addressing this so that we can ship a product in time has been a challenge.

Having said that, I just want to be super clear on one thing, we're going to do everything to solve these problems in quarters, not in years. And any delays we have this year, doesn't mean our orders or our customers go away? It just means we have to address it next year.

Yes. Got it. One question, I want to understand it conceptually. Deferred revenues grew substantially in the last few years. I mean this is -- it's a reflection of the environment. What -- how does it evolve going forward? And I explained what I mean by that, I don't mean orders. I mean what happens when a big customer finishes to build a data center? What happens when -- because these are joint data centers. So what should we expect with deferred revenues to do like step-down and revenue jump when someone finishes a data center? Or is there a smooth kind of line to the deferred?

That's a really good question. And again, history is always an indicator of what might happen in the future. So I'll look at some history first. We had a cloud super cycle back in the 2016 through '18 where deferred wasn't as big, but neither was the CapEx, but it was easily 10% to 15% of our revenue because people were putting in Neocloud data centers, our products were new, they were going through 100-gig back then super cycle, sometimes it was a use case in the leaf, sometimes it was in spine, sometimes it is at the edge. So this went on for 3, 4 years.

And then right around 2018, '19, when COVID happened, all these use cases became more mature. And I mean, COVID just put a lot of things into standstill, but you actually saw a deferred not only go flat, but pretty close to 0 in that time frame. So I'm not saying we'll go close to 0 because this is a much larger number, and we -- there's more shock absorbers. But you can expect that deferred, which is in my view, all-time high right now, will start to slowly flatten as these use cases become mature as the products become mature, and there will be this gap between new AI centers and old AI centers. So I don't expect deferred to remain at elevated levels forever. Eventually, they'll come out as revenue. And as the cycle matures, it will be a new set of use cases, maybe in scale up or scale across. So I think we are at an all-time high now. And it could get higher or lower, but I think more likely, it will flatten.

Got it. Another question I had, which is very specific about a single customer, but you disclose it. You disclosed that Microsoft is your largest customer. Last year, they did not do Ethernet. They did -- I mean, large scale, right? They did mostly InfiniBand. But this year, they are. And they don't use white boxes. You are their vendor. The interesting part is when I look at your disclosure, they grew 26% without having you in the back end, in the front end, they grew 26%. So what happens this year, meaning, what happens when you start to see Ethernet deployment in the back end? And what happens to the front end? Does it -- is there a parallel growth in the front end as well?

Yes. This is a question you keep asking that I've never done full justice to answering, which is like, hey, if you're growing in AI, why is your core business not? And I think it's important to look at these things not across quarters or even a year, but across multiple years, right? So as you rightly pointed out, in that particular hyperscaler, but in general, a lot of upgrades were going on in the front end between '22 and '25 right? And -- but today, if the customer has a $1, they're not refreshing the front end as fast. Guess what they're doing, they're putting all the investments in the back end. Now that doesn't mean it will last forever because once they finish the back end, they're going to put pressure on the front, right? And you got to do another upgrade cycle there. So there's this sinusoidal wave where -- when the back end goes up, the front end doesn't so much. And when the front end goes up, the back end doesn't so much. In a particular use case. And you multiply that times the number of customers, you get the picture.

So when you see our front-end slowdown, it means they already built it or they're focused elsewhere. And by the way, there was a period of time where they were neither focused on back end or front end, they were just getting GPUs from NVIDIA, right? And that was the largest bill they had to pay for. So I think if you look at it over a period of time, it all evens out. But if you look at it at a point of time, I remember saying at one time that the front end today is 2:1 over the back. I have to correct that statement now because now it's looking more like 1:1 because our back end is growing so fast.

Got it. So the question is also there is a cycle, and I don't know how to refer to it, but there is also a cycle of technology at the semiconductor level. So when Broadcom releases a new chip, right, like Tomahawk 6, is it a tailwind or a headwind? Does it give opportunities for new players, white boxes? Or because you're so close to Broadcom, does it give you the tailwind to actually grow even faster? What happens upon release of new technology?

I think any new technology tends to drive a benefit to Arista specifically because Ethernet as a standard is becoming kind of de facto standard, especially scale-out, but in the rest of the market as well. And as Ethernet continues to demonstrate leadership in the space, then Arista becomes like the natural choice. We lead the standards. We drive sort of the state of the art around that. As we've seen this kind of rapid advance from 800G to 1.6T. We're starting to even look at 3.2T. Like you've got people looking at the capabilities that, that provides and really considering building out faster and faster data center. So it just opens up more and more TAM if anything, accelerates Arista growth.

And just to add to that, if you agree with Todd, I think the beauty of our business is, while we are going to enter this 1.6T refresh cycle, we still got an awful lot of 400G and 800G going on as well, right? It's not like they died and it's either or. So we're actually seeing the benefit of a double cycle where one speed is taking off at 400, 800 and then you're layering upon since I like desserts, a multi-layer cake, and the 1.6T comes on top of that. So it's definitely an accelerator to the overall speed refreshes we're going through.

I want to ask you about the part of the number that we don't talk about, and I'll explain it in a second. So we talk a lot about hyperscalers. We talk a lot about campus. If I remove these 2 from your numbers, there is a 40%, 50% in the middle. And that is enterprise data centers. Now I have the luxury of covering both software and networking. And in the last cycle that we have seen now, I'm seeing the early bird that enterprises are investing in AI cybersecurity. And that is the prerequisite for investing in the network because you have to invest first in cybersecurity. Palo Alto reported it yesterday, Fortinet before. You can see clearly, AI is a driver for cybersecurity.

The question I have is from your guidance, this part of the network doesn't grow that much, meaning less than historical, but that's part of your conservatism. So I will say, I will add to you in line with historical numbers, 5%, 7%. What happens in the future? What happens to enterprise data centers? What are the drivers? And you're greatly positioned there. Is there any other -- like is there a market share discussion even? Or it's not about the market share, it's about market growth?

Jayshree mentioned this, cyclical nature of the spend. So as people start to shift maybe big focus on to AI than the traditional data center might slow that year and then back. But there's enormous growth opportunity here in 2 ways. Number one is we continue to see ourselves picking up significant use cases, specific important franchises across existing customer base in the enterprise. No doubt about that. But there are parts of this market that we have yet to reach. Arista is the market leader here, but we still have an enormous amount of TAM that we can go after, and we're seeing growth internationally. We're starting to see big university wins. We're continuing to pursue the big kind of traditional financial wins, but the verticals that we are starting to penetrate in real ways are amazing. Manufacturing, retail, university, et cetera. And these are big data center build-outs that are important. And so this kind of pursuit of the enterprise data center continues. And I know it's easy for it to get overlooked, but there is enormous opportunity. We're still reaching the rest of the market.

We're gaining enterprise logos. We're definitely gaining enterprise market share. And as you already know, we're the #1 in high-performance switching. But I think we have to be patient about it. It doesn't happen as fast. We don't get the instant gratification we do in the cloud and AI cycle because think about it, an enterprise data center is building and then it's usually a depreciation or a usage of that data center for at least 7 years, 8 years, 9 years, even if they put the wrong technology and we got to wait, right? So we do best in greenfield situations. We do pretty well in brownfield situations. We don't do as well in legacy risk-off situations where the enterprise customers just going to sit there with their assets and spread it out for a while. And you see all 3. But I think over the long term, and as you know, Arista has been built with our software and hardware excellence brick by brick, this brick shall come, too. It's just not the first use case, it will come a little bit later.

Got it. I want to talk about competition. So we -- 10 years ago, we spoke about competition with Cisco. We don't talk about it anymore because there's nothing to say. But the question is competition with NVIDIA because we do see NVIDIA growing in networking. Can you articulate how you compete with NVIDIA?

Well, I think it's one of those classic co-opetition issues where we are very grateful to NVIDIA because our AI business is almost always tying in to, 80% of the time anyway, into NVIDIA GPUs. So there's no way they're a competitor to us in the compute space. The more compute capacity they deploy, the more we can do with networking. But obviously, this tendency to build a vertical stack with NVIDIA, and there have been many examples of customers where the customers want to go with a horizontal best-of-breed network from Arista, but end up going with NVIDIA because of the customer gets a better bundled strategy, better support, better availability of the GPUs, et cetera. So there's a natural part of the TAM that's just not available to us because it's an NVIDIA vertical TAM.

Now having said that, again, we got to be patient here because I think today, it's largely NVIDIA GPUs. But we're very excited about the other AI accelerators that are coming on, both in training and inference. It hasn't gone unnoticed that we love the TPUs and the Google architecture that started way back in 2017. And naturally, we have a lot of opportunities to connect directly or indirectly to it. AMD and the MI Series is, again, we have deployed a lot of successful networks already together and every customer is looking for an alternate accelerator strategy.

There's a whole range of inference accelerators that are coming out. You guys saw the Cerebras IPO, but many of them are being built in-house by the hyperscalers, which is, again, giving us a lot of rack opportunity. So we love NVIDIA when we connect to their GPUs, but we love all the accelerators and frontier models to give us that diverse one network for all the diverse XPUs, if you will.

The one thing I might add there is there's also a story of building standards-based networking. Networking time after time after time has been an area where open standards have won the day eventually. And we're seeing that across the board. NVIDIA has some Ethernet technology available as well, but Arista leads the way. We lead the way in the standards. We lead the way, pushing the limits of the technology. And in the fullness of time, I think that becomes a driver for us.

Right. If I look -- if I start to try to divide the market between GPUs of AMD or others and between GPUs of NVIDIA, do you have -- do you think you have higher market share when the GPUs are not NVIDIA, when it's something else. And the reason why I'm asking it is because that part of the market is actually growing very fast.

Yes. The short answer to that is yes, because there is no vertical bundling going on. There is a best-of-breed approach over there. Arista is naturally the first and often only choice. And there's so much risk in this deployment, the last thing they want to do is go explore some speculative things. So yes, it is the fastest-growing market for us as well.

It's also when we get off of the NVIDIA GPU then the scale up part of the market becomes available, right? And that is a whole piece of the AI space we don't play in.

Okay. My last question, I don't leave much time for Q&A, but I wanted to cover it: optical integration. Your competitor, Cisco, does have an optical capabilities in-house. What is your philosophy, first of all, about optical integration, owning assets versus partnering with assets. And take it from there.

Look, our philosophy is definitely to work with the best-of-breed optical ecosystem. We don't have to own all pieces of it. There's a lot of physics there, as you know, and there's a lot of technology with lasers and co-packaged optics and Andy and the team introduced our XPO, which is the latest and greatest for pluggable optics for 1.6, 3.2T. So we are big fans of optics because wherever we sit, we have to connect to them, right? And it wouldn't come as a surprise to you that we worked very closely with Acacia before Cisco acquired it and continue to. There are good coherent optics vendor for sure, we see them.

Having said that, I think Arista's position is not always to be the revenue provider or the product provider for optics, but integrate into the optics really well, which can be integrated into our boards in some cases or work with pluggable optics and provide the right MACsec and root cause analysis works for them, including managing, all of that capabilities. But because that is such a specialized best-of-breed type of companies, just like security, we don't pretend to be that, but we want to enable that at a system level.

Great. Sorry, I took most of your time. But is there any question from the audience? We have a microphone. No.

Well, you took all their questions, looks like. Thanks for coming for the first early morning session here. I appreciate it.

Thank you, Jayshree. And thanks, Todd.

Thank you.

Thank you.

Thank you.

My name is Sebastien Naji. I'm the research analyst here at William Blair, who covers Arista Networks. I am required to inform you that for a complete list of research disclosures or potential conflicts of interest, please visit our website at williamblair.com.

I'm very happy to have Chantelle, the CFO of Arista, as well as Rudy, VP of Investor Advocacy, with us here today. And I think Chantelle will begin with a quick presentation overview of the company, and then we'll jump into some questions.

Sure. Are we good to go? Great. Okay, so good afternoon. Thank you for spending your lunch half hour with us. We definitely appreciate it. It's very nice to see you. For those who haven't met, I'm Chantelle Breithaupt, CFO of Arista.

And so just a couple of slides to orient. Many of you know our story, but just in case you haven't seen us in a while or are new, I just wanted to give you an overview. So here, we're 12 years past IPO, and here we are guiding $11.5 billion this year, incredible journey from a technology perspective. Originally started with the high performance compute getting into hyperscalers, cloud, enterprise data center and now we're talking all things that are AI. An incredible journey being $200 billion market cap, 12 years post IPO, and we feel we're just getting started. So thanks for being here with us.

Very happy to show different sections in the sense of where we're recognized by Gartner. So you can see from left to right, some of the Gartner positioning in the top right quadrant. 2025 for data center switching, 2026, just happy to see this here that we're now there for enterprise wired and wireless. Very happy to see that just getting into the campus and enterprise wired and wireless LAN. And 2024 with the acquisition of VeloCloud also being in the Magic Quadrant for SD-WAN. So I feel like we're making ground in a lot of different aspects of networking and very proud to have these positions to show you.

Why do over 10,000 customers choose Arista? They can see the robustness of our quality and our product and our ability to serve the customer extensible performance and platform. We don't like vendor lock-in. We like best-of-breed choices and are happy to compete in that environment. And then just having this really great real-time telemetry and AIOps that we will get into a little bit through the Q&A, I think, with Sebastien. That really makes us a great total cost of ownership choice when you're thinking about getting the highest utilizations from your XPUs. And it's not just how we feel this is the customer representation. So I think you'll find very few in the industry who can say they have an 89% score on NPS. And you can read some of the comments on the bottom, how they interact with our company.

Very delighted in the response time, very delighted in the technical capability of the team they interact with and just the approach that we're there until the end. Until they get to a performance and outcome they are looking for. So very proud to have that and congratulations to Ashwin and his team for getting the company to that position.

We talked at Analyst Day in September of last year. Hopefully, some of you were there about the growth in our TAM. I started in January 2024. Just before that, we were at about a $60 billion TAM, then $70 billion at the New York event we had in June 2024 and then Analyst Day updated that from $70 billion to $105 billion, so some pretty great growth there. And you can see at the bottom the different categories. Of course, a lot of it is driven by AI and data center, but also some great aspects that we see now that we have our campus portfolio underway. We're working on the next revision of this. And so stay tuned as we look at even a larger TAM amount in the different categories and the nomenclature that we'll use going forward. We also like to position our incredible platform and portfolio over what we call centers of data.

So we have the AI center, campus center, data center and the WAN center -- SD-WAN. And it's just to show the breadth of optionality that we provide to our customers. It's really we have a portfolio of products in what use case are they being used for across the different segments of our customers. So very proud to have this to get to their outcomes and their cost of ownership that they're looking for. And now we have this new nomenclature. We're talking about scale up, scale out, scale across, and I know we'll talk about that, Sebastien. But just to say, we're ready for this. We've been planning for this. We'll be working on it and very well positioned, I think, with our customers on this kind of co-engineering journey. What are they looking for from the largest hyperscaler and AI customer down to the enterprise.

From a revenue growth perspective, I think it's important to look at the growth that we've seen. We finished Q1 results in the sense of 35% growth. And if you look at the combined growth in the P&L 35% plus what it goes into deferred, which means it's shipped and invoiced and cash collected. You could say, basically, it was 54% growth. And you can see the subsequent quarters beforehand in the sense of where we've seen the growth combined between P&L and deferred revenue growth. And just to remind you of our guidance for this year, we did call out our guidance again, looking at 28% growth, $11.5 billion, maintained gross margin, which we're very proud to do in this kind of environment where it's a little tougher from a supply chain perspective. World-class, I would say, operating margin for a company like ours of 46%. We have given ourselves accountability goals when it comes to AI and campus. And you can see the growth in AI and campus goals versus our last year performance, pretty healthy growth for both of those sectors.

If you think about $3.5 billion of AI at $11.5 billion, a high percentage of our revenue is coming from AI. And then we've raised our CAGR for '25 to '28 to be 20-plus percent growth before that was mid-teens. So hopefully, you'll see these kind of signs of the demand we're seeing and how we're showing them through our guidance. And I think now we can go to the questions, Sebastien. Okay. Thank you.

Great. Thank you, Chantelle. I mean, maybe my first question, I wanted to start off very broadly. Arista really made its name over the last 10 years, filling this need for high-performance networking at the hyperscalers. Today, as we enter the AI era, you really hear from all the networking vendors about how strong their businesses have become. Cisco, NVIDIA, they're all talking about huge amounts of growth. So as we enter this AI era, how would you talk about Arista's maybe right to win or how it really differentiates itself versus all these other networking providers that are also talking about really good momentum from AI.

Yes. I think -- so thank you for the question because I think it's important to look at apples-to-apples in this conversation. But my leading answer in this is that we're -- I think Arista is very well positioned for AI. We've been waiting our whole 12 years post IPO for this moment. So I think all of the innovation we've seen up until now and the way we interact with the market leads us to be very well suited. And I'll give you some examples and Rudy, obviously, if you have anything, you can chime in. So let me start first with networking for AI, and then I'll talk about AI for networking.

So networking for AI, if we look at our product portfolio, some of the things I just showed here in the presentation, we announced the 800-gig Etherlink portfolio in June 2025. And so we've had that for coming up to a year, and we were very happy to see that AI was a great use case for 800 gig, and we were ready. And so I think if you take that 800 gig kind of Etherlink portfolio, combined with EOS, which is -- which was an operating system and software, which allows great utilization of the XPUs and all the performance criteria that we're looking for. And you look at the sense and the fact of all the experience we have with some of the largest, most complicated deployments.

There's a reason that we're currently the #1 branded vendor for front-end and back-end AI networking. And I think as long as we continue to innovate in the ecosystem, so we've been leaders in open standards when it comes to UEC, the Ultra Ethernet Consortium. We've been working on. You saw Andy announce XPO as a technology and working on ESUN, so we're working with the ecosystem there. And I think probably most importantly, combined with those things is that we offer networking that allows flexibility.

We're agnostic when it comes to the NIC, we're agnostic when it comes to the XPU, we're agnostic when it comes to the optics choice. And so that allows -- because every customer wants to do it differently to reach their goal, and we're happy to do things differently with each customer. And I think that will continue to innovate. And if we keep that pace, we absolutely, I think, have a right to win if we execute with the customer. So that's networking for AI.

AI for networking. Now we're talking about all the things we're doing to help -- AI help networking, and we have this great suite of products called AIOps. It includes AVA, which is our virtual assistant. We have agents and we have insights that we provide that sit on top of NetDL. And so when you combine all of these things, I think we are the best positioned AI pure-play networking company when you're talking about the networking data center part of it.

All right. Great. That's helpful. And then I want to maybe ask about what I think a lot of investors are curious to talk about, which is in your most recent earnings call, you started to talk about more acute supply tightness, having to manage very longer lead times. I mean, could you maybe talk a little bit about how you are managing that supply and whether you see lack of supply potentially being a headwind to your growth, either near term or even over the next couple of years?

Yes. I think it's a good question. I think you're starting to see more companies at least speak a bit more openly about -- the supply chain has some constraints, but it has no constraint in the sense of us reaching our FY '26 guidance and we'll continue to take quarter-by-quarter what that could mean for future guidance calls as we go through this year and next year. I think from the perspective of looking at the different arrangements we have. So we deal with some of the biggest suppliers and have great arrangements and histories with -- history with them, along with working with our largest customers. And so I think we're well positioned in the sense of when it comes to availability, I consider it more about when, not if, and so if you think about a lot of our customer conversations, our 12 months, excuse me, in design, 12 to 18 months into design, the 52-week lead time we have on average, I think we'll serve that well. You've seen our purchase commitments go up pretty substantially to lean into the next 52 weeks coming into next year.

So I think we're managing it well. I think where we're talking about the constraint. The constraint could come in if someone's asking to have something not within the lead time that's material. How do we work within the ecosystem to have that kind of burst demand. I think that's the part we're just acknowledging it's not as easy as it was but we'll do everything we can with our arrangements to have that. We're seeing incredible demand. We just want to make sure people understand within the lead times, that's okay, but perhaps between a burst of demand. We just need to think a little differently how we can serve that.

And that supply tightness, I mean, is it really broad-based? Or is it more acute in chips and wafers and memory...

It's a bit of Whack-a-Mole. It's a bit of a Whack-a-Mole. I think that memory was the first one, and I think we started talking about November last year, and I think we've gotten to a good spot on memory. I think other components come and go. I think that from a perspective of -- it's not just one vendor or one supplier or one product. It really depends on the time and what's happening with a specific deployment. And so I think it's not bespoke, but it's not generalized. So I'd hate to generalize too much across one category. It really depends on timing and innovation and what our customers are looking to deploy. So from that perspective. Now on the other hand, we've actually reduced campus lead times. So our campus lead times are now down to 6 weeks, which I think absolutely gives us an advantage as we start to go after the campus market share.

Got it. And then I think the other area that investors have a lot of interest is in this product deferred balance that has really continued to grow over the last 12 to 18 months. And my estimate is that it's around $3.5 billion, $3.6 billion, which is way larger than it's historically been. Could you maybe unpack a few things first. Is that mostly driven by some of these AI products, these new SKUs. And then you've talked in the past about you have to hit an acceptance criteria for that to flow into revenue. What does that acceptance criteria entail? Is it the networking hardware is plugged in? Is it when the GPU rack has a certain utilization? Maybe just help us understand how we should think about that deferred product starting to flow through into the income statement?

Yes. I think that -- so absolutely, so the concept and construct of deferred has been with Arista since basically we started doing cloud deliveries. And so -- but what you're seeing now is it's the same construct, just much bigger market and deals, right? So during cloud -- and we have some information in our earnings deck, if you go to our Investor Relations website, but you see there, there was like a cloud cycle, and now we're in this AI cycle and the AI cycle definitely surpasses from just pure dollars, the cloud cycle during that time frame. So same construct, bigger dollars flowing through and more complicated. So it is new use cases. It is new products and sometimes new customers. And so from that perspective, things are arranged with the customer where we have to meet certain criteria, acceptance criteria.

So it means it's shipped and it's invoiced and cash is collected, but it is in deferred until those milestones are reached. Those milestones can take 12 to 18 months, sometimes a little bit longer for the most complicated largest deployments. And it could be a variety of things. It can be by site, it can be certain engineering things that we've promised to co-work with the customer. It could be that, from their perspective, a certain design element has been reached. And so there are different -- again, back to every customer does it differently, but the premise is the same until we're sure that it's up and running the way we have agreed to, that's when we take the revenue.

So it is mostly AI that's in deferred right now because that's the largest use case we're seeing. And it's a great example of demand, but customers also enjoy that we have skin in the game until they're seeing great performance outcomes.

And then I think you started to talk about -- historically, you've had 2 major cloud titan customers M&M as you guys like to refer to Microsoft and Meta. More recently, you talked about expanding that to 3 customers with 10% plus, maybe even 4 customers over time. What is driving that increased diversification and some of that traction you're seeing with hyperscalers that maybe historically haven't worked as much with Arista?

Yes. I think that we're absolutely -- as we get older as a company or further in our growth cycle as a company, we are looking to diversify. It just takes some time, right? So we have customers A and B now that we call them, we're using a letters to denote now that we expect more of them to come in. I think that -- so there's a few things that I can drive at. One is, AI is a great use case. But generally, anywhere that we're switching to Ethernet networking being an option, that's where we're going to start to see where we can have some more business that we didn't have before.

Now obviously, to get to this greater than 10% customer at the -- I'm sorry, I can't see you guys, the range we're talking about, they're not coming in with just one deal and becoming over 10% customers. So they have some existing business, and they're getting to over that 10%. And so it can be companies that are using Ethernet that didn't use it before. It could be new kinds of customers coming to market in some of these segments you've talked about, maybe the new cloud sovereign AI, these sorts of new customers that are coming in. So we'll wait and see where we report at the end of the year. But we're fairly confident that third one will come in. The fourth one, as we mentioned on the call with Jayshree, we'll have to see exactly where that lands.

Got it. Great. And I think I'd be remiss if I didn't ask you a question about white box.

Sure, yes.

So we'll ask you a question on what are you seeing in terms of the competitive dynamics there? I think over the last year, Arista has done a good job of kind of laying out your blue box strategy and your differentiation there. But given that a lot of these white box vendors are reporting really, really strong results. Are you seeing any increased traction at your customers for white box? Are there certain sockets where white box makes sense and others where you have to go with Arista?

Yes. I think -- I don't think anything has changed in the dynamic in the sense of which use case is a white box use case versus a branded vendor. I don't think that has changed at all. And so that remains the same, and that's a boring answer to that question. I think -- so that remains the same. I think what you're seeing is potentially when you're talking about these growth vectors Sebastien, it's okay. At a point in time, you ship, you drop it on a dock and you're done. Okay. Well, that's recognized right away. So that feels good in that moment because all that's coming through at that point in time. So there's probably a difference in the sense of the timing deployment and how that comes through because you have to also take into account our model, which has the deferred. But we're not seeing anything that changes in the use case. It's the same -- and we appreciate the dynamic.

And so I think that we understand there's a spot for white box in the deployments, there's a spot for branded vendor. And sometimes that choice for very select customers because you have to be able to have the team to support a NOS on a white box environment or a blue box environment. So you're not talking smaller companies that can usually do this because then you're talking a CapEx versus OpEx trade-off, it's usually not for free, right? And so from that perspective, we find it's very few customers that can even attempt to get into that scenario from a just a cost ROI perspective. So we don't think anything has changed. We don't think there's anything moving differently. If anything, we would probably double down that it's becoming more complex and the utilization of the XPUs is becoming more important and critical, and that would be in our favor.

And maybe staying on the theme of competition, NVIDIA has really emerged over the last couple of years as a real networking competitor. They talked, I think, on the last earnings call about a tripling of their Ethernet business. How do you go about competing with someone like NVIDIA, particularly given that they have an ability to potentially bundle their networking with their compute and all the other parts of the stack that they're selling. And where do you really see that you differentiate when you're talking to customers versus the NVIDIA spectrum portfolio?

Yes. So first, just so we are completely thankful to NVIDIA for basically opening up this GPU market, and so we're very thankful because we participate in connecting those GPUs. So it's not all just competitive relationship between us. There is a partnership relationship that way. But if you get down just to networking, the type of networking we do, we have to be careful we're looking at apples-to-apples, and then I'll get to the competitive differentiation.

So Ethernet growth can also have NICs, it can have NVLink, it can have other parts that aren't part of what Arista would compete in. So I would encourage everyone to look at the apples-to-apples comparison growth and see what that growth is. And I don't think it's the same growth number trajectory you were just mentioning. And I think that aside, so how can we compete because we can speak to what Arista can do. I think, again, with that phenomenal portfolio optionality, what we can do is compete on the options you have to have to build best-of-breed, the agnostic capability to bring in other XPUs, et cetera, and the best-of-breed usually is a good choice for our customers. They want to have the optionality.

So if they're open to that, we have a good chance of winning. I think that in the sense of if you look at the other factors we talked about, things like EOS and AIOps, those are also things that they're delighted to have. And sometimes we see customers get into a vertical stack and then come back later realizing they want to go best-of-breed. So maybe it's not the first time, but even the second time that we see them. So there's lots of options where we can see them and come back to them. But those are some of these scenarios where we absolutely can win for the networking part.

Yes, that's really helpful. And then I wanted to ask maybe about a longer-term trend, which is this shift to co-packaged optics that everyone is starting to talk more and more about. And then I think relatedly, Arista right before the optical conference in March, introduced this concept of an XPO pluggable cable. Could you maybe just talk about across both co-packaged and the XPO cable? What exactly is Arista's opportunity? Is there a way for you to monetize these trends? Is any of this a threat, particularly the CPO aspect.

Rudy, do you want to take this?

Yes, sure. So in general, optics are not a big part of our revenue, right? So we certify and kind of resell optics, but it's not a big part of our revenue. So really, our work in optics has really been about moving the industry forward. If you go back 10 years, we introduced OSFP, which is kind of getting to the end of its usefulness, if you will, right? And so we were really ready for a next generation. Now when you get to that next generation, you certainly have one option, which is going down the co-packaged route. Or can you extend pluggables. And so what XPO allows you to do is extend pluggables and comes with the benefits that when it's pluggable, it's a lot easier for customers to service them in the field. It also uses the same supply chain that OSFP has used for the last 10-plus years, right? So there's significant advantages there. And one thing that I think sometimes goes unnoticed with XPO is it shrinks the physical size of the networking stack, right, by reducing that front panel density or I guess, increasing the density and therefore, shrinking the size.

What that does is it opens up a whole bunch of other options for doing things like scale up, right, where you can do things like copper for longer, where you can do things like micro LEDs or RF. So frankly, solutions that are more efficient from a power perspective, from a dollar perspective, then going down a purely optical front. Now perhaps we get to a point where co-packaged optics are inevitable. We are absolutely agnostic to it, right? Like we don't believe that co-packaged optics is a negative for us, we -- if anything, the engineering involved with co-packaged optics and making it successful, it's going to be super important. But I think what we're hearing from customers is, a, delay co-packaged as long as possible. That's where I think XPO comes in. And when you do go down the road of co-packaged make it as open as possible because what customers don't want to do is be locked into a single supplier, a single vendor.

Because today, they're not buying their optics from their switching maker. They're not buying their optics from even the chip maker. They're going out to Asia and buying the optics directly from the supplier. And that's given them tremendous leverage. They don't want to be stuck in a place where they're having to deal with margin stacking and things of that nature. There's both tactical reasons and financial reasons why I think we're trying to delay as an industry CPO for as long as possible. And that's kind of what we hear from customers. But when CPO is ready and necessary, we feel very, very well equipped to be there.

Got it. And is it right to think that a CPO chip just becomes part of your bill of materials that you build around essentially?

Yes, pretty much, yes. With -- again, like I think the bar for failure in the CPO switch is far higher, right? Because if a switch fails with CPO, essentially the switch has to be taken down. Today, with a pluggable, if one optic fails, you take that one optic out of commission, which means whatever workload is plugged into that, not the entire switch. So if anything, I think the hardware design, the reliability that we've done so well with over the last 20 years is going to become even more paramount. So we feel very well equipped for that. But customers do want us to try and delay that inevitability, if you will as long as possible.

Right, right. And then maybe on the theme of maybe longer-term risks or threats, Google uses a lot of optical switching inside of their TPU racks. What -- are you concerned at all that you could see more and more hyperscalers move to optical switching? And if so, does that present a risk to the packet level switching that you guys are so good at?

I'll take that one as well. I mean, I think what we've seen is optical switching has a very specific niche use case, right? Google, as you pointed out, has been the most -- the biggest proponent of it. But if you've seen some of the recent announcements from Google, I think even they're admitting that once you go beyond a certain scale, really go beyond a scale-up domain where you're dealing with a fairly uniform kind of workloads, right? You have to go Ethernet because that per packet switching capability, the ability to decide, okay, where does this packet go as you look at each packet and look at the header is tremendously useful, right? With optical switching, what happens, you're literally pointing the mirror in a different direction, right, as you want to move stuff around.

So it doesn't really work well for any kind of real-time decision-making on, okay, what this package should go there. So as workloads get more heterogeneous, as workloads get more -- have higher entropy, really, over time, Ethernet has always won, right? So we don't feel like that's a threat. And like I said, the recent Virgo announcements are, if anything, a testament that while OCS has a space in the network, it's more confined to these narrower use cases. And once you want to go beyond a certain scale and beyond certain types of workloads, really, I think, Ethernet won that battle time and time again over the last 50 years.

Sort of simple optical path, simple connections...

Correct. Point-to-point where you're not expecting to change things dynamically on the fly.

Yes. Okay. And then maybe here in the last few minutes, I could turn the questions a little bit to the enterprise business.

Sure.

You guys closed this acquisition of VeloCloud, which is an SD-WAN technology about a year ago. Could you maybe just give us an update on where you are with that integration? And if you started to see any success in cross-selling either the VeloCloud customers to more Arista products or vice versa?

Yes, we are -- I am personally very happy on how VeloCloud has come along. I think that it was the largest acquisition we had done as a company and a lot of great work went in to making that happen and the integration has gone well. We are functionally integrated. So everyone's kind of gone and joined the teams that they recognize functionally. But most importantly, we've had great conversations with the customers. I think the customers are very excited that now it's part of the Arista family. It's part of -- in the sense of the care and attention we can give it, given we're 5,000 people who focus on the portfolio and networking. So I think the customers have received it well. They've given us great feedback in the things they love us to focus on, and we have a team dedicated to working through those. So I think it's gone as well as expected and very happy to have the team there, a very talented team, and they've stayed with us.

So I think that's a testament that they're enjoying their time and happy to be part of what we do as a company and our culture. For cross-selling, I think that given it's just coming up to a year, I think it's pretty good progress. We've gone through all the functional integration of everything from quote to cash and getting all the renewals and licenses sorted out. So that was a lot of just transactional work. Now the real customers of the cross-selling are happening. We're seeing it in a few of the enterprise segment, and it's both ways. It's VeloCloud into existing Arista customers and Arista into customers we did not have before. So it's good customer acquisition. But it's still early days, but definitely a pipeline is building. And I would say that's on track with what our expectations were from a deal perspective.

Got it, right.

Two things I would maybe add there as well, right? One is, it has opened up a new route to market through the service providers because they had a pretty robust service provider business as well. And then the other thing is from a campus RFP perspective, often SD-WAN is becoming a checkbox requirement, right? And so having that whole portfolio allows us to bid on campus. So even if it's not a direct upsell, cross-sell, it allows us to bid on a project that maybe a year back, we would have been disqualified because we didn't have an SD-WAN solution.

That's great. Okay. And then maybe just last question, again, on the enterprise space. I think last year, you had talked about the pending Juniper, HPE acquisition as potentially driving more leads, more interest from customers. That acquisition closed about a year ago. Frankly, it sounds like it's going quite smoothly for the company. I'm wondering, is that still an opportunity for Arista to take share from that customer base? Or has that maybe become less of an opportunity?

Yes. I think that from our position, we're starting at 3% market share in campus. So we're super excited to the upside. And we're also excited that there's a great refresh cycle coming up in the next few years and perhaps there's a pull in of the refresh cycle as campuses get ready for AI and their AI story. So there's a lot of goodness there and we have the portfolio to serve. I think at 3% market share and the overall market is growing maybe high single digits, we're -- our growth is going to be share-taking. And so I won't comment on specific who we're taking it from, but I can say that if -- our road map is clear, and we're winning campus first deals, and I think the more we can rinse and repeat that and have them as references, I think our share taking from whoever the incumbent is what we'll be looking to do.

Right. So we only have a few minutes -- seconds left. So maybe just if you can give us your updated view on capital allocation. I mean, that's one of the benefits of Arista as you guys have great margins and very high free cash flows and they're only going up. You've made some acquisitions, but not huge ones historically. Could you maybe just talk about how you think about M&A versus potentially dividend, potentially more share buybacks?

Yes, sure. So our capital allocation, just in a nutshell, remains the same. Organic investment, marketable securities because we're still getting very strong interest income in this environment. And then it would be share repurchases and then M&A. When it comes to M&A to answer your question, nothing obvious. We don't want to break the culture, and we don't want to go into something in new adjacency. But if we see something more maybe in the AI space, either talent or tech, that's probably where we'd be looking.

Okay. Great. Thank you very much.

Thank you for your time, thank you.

Thank you all for coming. We're going to have a breakout in -- Anna, where is it? [ Mar ]? In [ Mar ].

Hi. Good afternoon, everyone. Welcome to the fireside chat here with Arista Networks. I have the pleasure of hosting John McCool, who is the Senior Vice President of Platform Hardware at Arista; Tyson Lamoreaux, I hope that I got that right, SVP of Cloud and AI Networking; and then Rod Hall, who's probably not new to a lot of people, but Investor Relations and Finance at Arista.

Yes. Thanks, Samik. Yes, it's great to be back. Thank you for having us and organizing everything. It's really good to be here. And I'm going to kick off with a couple of points, and then I'm going to get -- we're going to get to your questions. But we -- two high-level themes that I want to flag to people and then I want to make a couple of points.

High level, there's 2 things you need to take away from this. One, Arista is extremely good at managing the supply chain. We -- if you go back to COVID and you don't have that -- maybe some of you don't have that history with the company, we went into COVID and ended up doing better than most others in our area in managing supply. And so that's why we've got John McCool here with us because he's the key guy that ran all of that, and we wanted to give you all a chance to hear from him and talk to him.

The second thing we want to leave you with is that our products are, from a value point of view, absolutely incredible. And we are doing extremely well from a competitive point of view, and that's why Tyson is here because he's Head of our AI and Cloud Networking Group and can, I think, articulate the value of those products really well. So those are the 2 really high-level things we want to say.

Low-level, we know there's going to be a lot of questions on supply. Samik has got a lot of questions for us as he's going to ask, but we are talking about an industry-wide supply problem. We don't believe this is specific to Arista. We've been dealing with supply issues for quite a long time, and we've called out long lead times for some of the components for several quarters now and that continues.

What we don't believe is this is necessarily changing anything from a revenue point of view for us. We already are in a situation where we can't ship as much product as we have demand for, and that's been the case for quite a while. But you will have seen in our recent earnings deck that we put out after earnings, we updated it any way, we're talking about a 20% CAGR for 3 years for our revenue, 20% plus. And that's meant to give you some idea of the confidence we've got in our ability to deliver revenue even in the midst of this difficult supply situation.

The second thing I want to say to you is that our margins remain stable. We have kept our margin guidance unchanged at 62% to 64% for the gross margins for this year. And we do that for a reason because we can demand value for these products. We've already put one pricing change through. We hope not to do any more. We want to be good partners for those customers that we work with, all of our customers. But at the same time, we're a company that has been able to demand value for its products. And I hope, as you hear from Tyson here, you'll get a better feeling for that. That's all I got to say. Over to you, Samik.

Thank you. Thanks. So that's a good overview. Now let's dive deeper, start with supply. We'll come to the cloud companies and the demand drivers in a bit. John, what are you dealing with in terms of biggest constraints on supply? And to Rod's point, how do you see the supply situation now, similar or different to what you had after COVID?

Yes. So different to COVID. So let me just start with supply. What we really see is a demand-supply imbalance, right? And Jayshree talked about on the call demand being greater than anything that she's seen in her tenure. So with that demand, capacity for advanced semiconductors have been put in place 2 years ago for this year that we're facing. As these folks are building out these big AI data centers, they really have 3 constraints. One is energy to fuel those data centers, the physical construction of the data centers and advanced components, whether that be 5-nanometer, 3-nanometer process nodes, advanced memory technology, CoWoS packaging and packaging test, DSPs for fiber optic components. So that's what we've been up against.

If you take a look at our shipments, if you take the revenue that we had in Q1, plus the deferred revenue, which actually represents physical shipments that we made from our factory, we were able to overcome those supply constraints and grew 54%. But we talked about on the call that we are living in a supply-constrained environment, and it is around those advanced processing nodes.

Any change in prioritization from your vendors in supply chain to Arista because that's been a big topic?

Absolutely. Yes. And just kind of back to the question about COVID and maybe what's different. In COVID, we started out really with a supply constraint. There were no people to build anything. I mean everything stopped. And that started to shift again to a demand profile later in. And if you think about it, that demand, part of it was IT. We were all working at home. There were a lot of computer and desktop upgrades, but we were also buying new cars, we were doing DIY projects and needed drills that had 10 FETs in them. So the things that were short were things that were broadly based across all electronics, whereas this is singularly focused around the components that need to go in AI.

In terms of prioritization, look, I think we're well represented by our suppliers who have an enormous seat at the table at TSMC as well as our customers. What we saw during COVID is our suppliers that needed to build out advanced networks to support their capability really represented us well. We haven't had to invoke that in terms of this current supply constraint, but I think it's really well recognized that our customers will need networks to connect their GPUs, their CPUs and the underlying pieces that put together their AI infrastructure.

Got it. Got it. Okay. Maybe moving down that path a bit more, let me phrase one more question, and I think Rod touched upon it a little bit, but you've talked about being a good partner to your customers, not doing multiple or aggressive price increases. There was some indication on the call that you could be looking to sort of help customers out and there could be some hit on gross margins on that account. Just maybe address those concerns while also talking to the purchase commitments that you've done and how do those help customers? And do we eventually get to a point in the tightness of the supply chain where some of those aggressive price increases or multiple price increases just become inevitable for you?

Sure. We already saw that with memory. And coming back to the comment about gross margins, what we were saying on the call is we're really going to lean into the business because of the demand. So in Q4, we began to see that sharp increase in memory prices. We went out and secured supply. We made the price adjustments in Q1. So there was some disconnect between the timing of our consumption action against the price increase. And we're going to be aggressive in terms of getting supply to meet this demand and there may be some lag between being able to pass that on to customers. But we absolutely have the value to really bring those price increases forward if there is an underlying cost increase.

Our customers are quite sophisticated. We've been with them for a very long time. So we don't believe in really kind of leveraging this moment to increase prices. They're also very sophisticated to understand the underlying mechanisms that would drive a cost increase. And no one's happy about price increases, but they're open to the conversation and have supported us in the past and are supporting us now with the memory increases that we've made.

Okay. Rod, for you. The decision to upgrade your long-term target to 20% following the earnings call, maybe just walk us through the thought process there and what drove that?

Yes. Before I say that, I also want to -- John made a point earlier in some of our meetings, we could have increased our margins quite a bit more during COVID and we chose not to do that because of these long-term relationships. So I thought that was a really good point that you made. It's not a commodity company like memory where we just double our margins when we can grab up that margin. We have these long-term relationships. We want to be good partners. So that's something to think about, even though we did keep good margins through that period.

In terms of the growth CAGR, I mean, I guess what we wanted to do, first of all, mathematically, that number, the mid-teens number we put out back in August didn't make any sense anymore in the light of our 28% growth. So that was one thing we just thought well, gosh, this doesn't make sense mathematically. But secondly, we wanted people to understand that we have confidence in our ability to deliver revenue even in the midst of this situation. So we wanted to just put some highlighter on that, make sure people understand that.

And higher number would have been more helpful, I can tell you that.

Yes.

Yes. The other thing that I think we addressed in that update was around deferred revenue. And as we were having callbacks and discussions, a lot of people conflated to discussions some people are having around order growth with deferred revenue and deferred revenue is actually things that we shipped, we've invoiced, we built and represents the growth of our shipments. So that also is explained a little bit better in that deck.

Okay. So finally, Tyson. You built one of the largest cloud networks in the world before coming to Arista. When you look at now the network architectures that your customers from this side of the lens now, the customers that are designing today versus even a year before or 2 years ago, what surprises you most in terms of how quickly things are evolving with your customers?

Well, I mean I think it's the rate and volume of change like -- and what I mean by that on 2 dimensions, the rate of change is just the quick turnover to new architecture. Some of our customers are super ambitious and their goals, objectives are unafraid of putting multiple types of competing architectures into production simultaneously and unafraid to walk away from ones that they determine don't work, don't scale, don't meet their operational criteria. We have some others who are a little bit more methodical and iterative, but their iteration cycle has shrunk. So that rate of change has increased dramatically. We've even seen it in the optics. We've seen it in silicon. It used to be accepted that you would see a new switch every 3 years. And now we're talking about 18-month cycles on accelerators, 18-month cycles on switches. Those go into new architectures. Because the architectures are advancing in parallel to the switches being built, there's sometimes some dissimilarity in terms of what is intended to be done and what can be done.

And so you see some of this iteration also apply to taking what they can use today, like maybe a Tomahawk 5 switch and deploying it at smaller scale in an architecture that's intended for something along the lines of Tomahawk 6 or maybe it's going to go out and air cooled and plan to convert it to liquid. But it's energy, it's link speed and transmission rate, it's reliability, it's the radix, the total bandwidth of the switch. You're seeing a lot of stuff evolving around protocols now at a much faster pace as well. The argument around scheduled versus unscheduled fabrics, the argument around switch-assisted computation, the argument around leveraging new protocols like the MRC protocol to be able to do better multipathing using the network silicon to assist in this as opposed to just purely unscheduled fabric, but having a protocol-native mechanism for it.

So this happens at kind of every customer, but across several customers, and then you look at across our product set and this is where kind of the volume kicks in. It's a lot of parallel change across the entire product stack kind of at the architecture level, at the system level and it doesn't really show any signs of slowing down. I mean we're staring at 1.6T coming, 3.2T is right behind it, optical technologies are evolving into XPO and CPO are coming as well. And then when we look at the clusters, john talked about the constraints in getting data centers online either due to power or real estate or construction or construction-related materials, you start to see things push around distributed training or novel ways of interconnecting locations together to drive inference or a combination of inference and training traffic.

So I think that this is similar to the cloud in several respects, but so much more on a much more compressed cycle. And hard to see when we're going to reach the peak of it. I mean it still looks like a lot of runway ahead of us to keep going.

Okay. So maybe turning -- going more specific here. A lot of attention recently around one of the large cloud providers publicly describing and detailing a new scale-out accelerator fabric, purpose built with higher radix commercial switching in a flat 2-layer topology, right? It looks on paper like a great fit for Arista?. Just talk to us about how you interpret the specifics there, and whether Arista would be well positioned with that cloud company or not in terms of their new scale-out fabric?

Yes. Well, I think your assessment of it looks great on paper, I would agree with. I mean I think that like anything that resembles our Tier 2 leaf spine architecture, higher radix Ethernet, anything that's Ethernet plays very well to our heritage, to the products we've built, to the ongoing investments in R&D that we're driving around the products that we're going to be building in the future. So ignoring the specific customer, generally, we think this is a nice validation for what we've been saying all along, which is open standards, ecosystem, interoperability, Ethernet tends to win out in the end. Customers want choice. They want to be able to choose the best-in-breed suppliers to work with. They need partners who can be an extension of their engineering capabilities and can help them achieve bigger things faster. And when we're talking about this accelerating and compressed innovation cycle, a lot of architectural level, a lot of industry-wide evolution happening.

Supply constraints. You need companies and partners that can move at the level of kind of dynamic that you have and can impedance match. So I think we're very well positioned for this type of architecture in general. I think we're building products that slot into this really well. And I think our company, in terms of its product, its operations, its capabilities also make for a wonderful fit. So we're going to go fight to try to win every one of these Ethernet deals that we possibly can, that's for sure. And we like to be part of the story there at this customer and the others.

What's exciting to me about that is if you think about 8 quarters ago, at a conference like this, we'd be talking about this Ethernet even have a role in AI, and that was all InfiniBand. We talked about the back-end network and the potential TAM. We tracked 4 customers. And if you look at our guide now for 2026, 30% of the business will be AI, right? So that's really exciting. And I think the continued validation of Ethernet and the scale-out architectures continue to drive that growth.

Let me ask you a follow-up on that, Tyson. As much as Ethernet adoption broadly is stable for Arista, what are you seeing in the competitive landscape for higher radix switches? I mean, to us, on the analyst side, hieratic switches just seems to be a great fit for Arista, but are you seeing more competition at that level of capability that you particularly do well in?

Yes. There certainly are some competitors who are aggressively pushing in for denser, higher radix switches. Some of this is kind of what I would call kind of a mixed modality, which is kind of a multi-RU or multi-OU system with several chips in it, but they kind of operate as disparate independent planes or nodes versus something more sophisticated like our modular chassis, which is kind of the largest that you can get, but it operates as a single unit and substitutes optics and cables for traces, for communication efficiency and in the case of high bandwidth and high link speeds cost savings as well. I mean, it's -- copper is always going to be cheaper than optics. And so we see competitors understanding that there is market for this and entering, but we really think we have great heritage in building here. We have a tremendous team that has been building these products for generations.

Now we've got really sophisticated customers that we've been working with in kind of somewhat of a joint development model, right? We're co-engineering together, looking down the range and saying, what are the constraints that are going to affect kind of our next-generation decision-making? Where do we need to be? Where do we need to place our systems? And that allows us to get out in front and build, in a lot of cases, some of these products that we ship that are pathfinding for our general purpose products, things that you wouldn't find in the Arista catalog on the website, but we're deploying at scale.

I think some of our competitors have recognized that, that level of sophistication exists and those opportunities exist. So they're incented to invest. Whether they can do it as well as we can, I mean, it remains to be seen. I think we're going to continue to focus on relentlessly executing with our customers. And then we generalize those things into architectures and systems that we can sell to the broader market, and that's where the enterprise follows and the Neoclouds consume and kind of slot into that quite well as well. So yes.

Maybe let's talk -- move to talking about scale across a bit. You indicated on the call, it's going to be about roughly 1/3 of your AI revenue this year. Why -- how -- like what drove -- what is driving the number to move so quickly? I mean this was practically nonexistent last year. It is going to be $1 billion almost in revenue, $1 billion or more, I guess, I should say, given your track record. But what's driving the number to move this quickly?

Yes. Well, like John said, I mean, the AI revenue even a couple of years ago was almost nonexistent. So that this one can grow independently is not super surprising. We do see some customers that are adopting architectures that heavily feature scale across inherently in their design. They're working around the data center space and power constraints proactively by saying we're going to adopt smaller tens, low hundreds of megawatt facilities, getting them together and construct them into a fashion that inherently requires on a scale across solution. Others are building massive campuses where they're layering in data centers over time on a singular campus and then the scale across works to interconnect all of those together as well.

We've also seen some novel architectures even on the inference and agentic side where customers are creating more of like an interconnect fabric for inference and access to different clouds and on-prem capabilities to power agentic. Some of it is redundancy, some of it is latency optimization, again, following principles that we've seen similar to kind of Edge computing and cloud really and its evolution into the Edge. And so -- but in terms of like is 30% durable, should we expect that every year, can it grow? When we think about the mix within the AI bucket, I think it's very dynamic still because there are so many architectures running in parallel. There's new systems and new silicon shipping in the next 12 months, another 12, 18 months behind that. These things are going to inevitably affect the architecture that folks are deploying.

I think we're a long way from seeing coalescence onto a common kind of set of design principles in AI. There's still going to continue to be a lot of experimentation. And as long as we're working around constraints, I think we're going to see mix shifts between whether it's a bigger singular facility with a lot of scale out versus more scale across. But I do think, as agentic continues to grow, as it gets commercialized, adopted, enterprises adopt, we're going to see more push to the Edge. That definitely serves -- or we have good products to serve that use case well in the scale across arena.

In the early days with the 4 customers 6 quarters ago, it was easy to track these ratios. It's getting really hard because they might build out different pieces of the network at different times. So it's difficult -- more difficult to see the alignment of the ratios...

Yes. Customer mix and then architecture choices within them for sure...

I mean scale across for inferencing has been coming up more and more. Are you able to delineate when you engage with the customer, whether it's a training, let's scale across or whether it's already planning for inferencing driven by that?

Yes and no. I mean, insofar as we have deep engagements with those customers, we have a sense of what we're doing, what we're competing for in the business and what their configuration and their architecture concentrates on and product selection. It's a little bit easier to differentiate. But again, some of these things are very temporal, right? There are decisions that are a moment in time. There are several customers who are building scale across to interconnect data centers, who, if they could gain access to a single gigawatt facility, would much prefer, right?

And so they're going to continue to work their own supply chains in parallel, data center side, compute side, storage network and converge it all. So sometimes we're going to be a lagging indicator of some of these decisions, sometimes our mix of our own products and shipments will just reflect some of that customer choice and how they solve for the constraints that they're facing. But broadly speaking, yes, I think the customers who concentrate on agentic, on inference, we can differentiate those pretty easily because there isn't the associated training workload running with it.

You brought up this earlier, Neoclouds or call it -- or maybe you can even take the segment that's just the Frontier AI labs working on Frontier models. Historically, when we look at the large hyperscaler space, your customers there, you've co-designed, innovated with them. What are you now seeing in terms of engagement model from the Frontier AI labs? Are you co-designing with them as well? What's the magnitude of the breadth of the customer vertical that you're looking at?

Yes. Well, you would have seen the press release this month of the MRC protocol spearheaded by OpenAI with a lot of partners, including ourselves. So we are deeply engaged with the Frontier folks. We treat them a lot like our hyperscale customers in terms of knowing that they're super strategic in the industry and the market. We have a lot of faith that they're going to continue to grow. We want to be able to grow with them. We want to be able to support and help power their growth as well. So those tend to be a lot of more deep relationship kind of close co-engineering, engineering extension kind of relationship. Some of them are earlier phase in terms of moving down the stack where they may have started in the cloud and they're taking on more and more of their infrastructure. We're uniquely suited to help come in and help them build to solve those problems. So that is part of our go-to-market motion when we're working with these folks is like how can we help fill in some of the gaps with them on staffing capabilities, architectural choices.

And so the motion, I think, and the engagement model looks pretty similar to hyperscalers in many respects with a lot of these Frontier folks. And certainly, even on the Neo side, as they continue to grow and become bigger entities, vice versa kind of -- it actually looks pretty similar there.

I think they recognize that token -- I've been doing some work on token economics. Token production costs are very sensitive to network performance metrics. So if you change latency or jitter just a little bit, you can really -- you can very quickly blow up your token production costs, and they're aware of that. So that's why they're engaging with a company like us.

Actually, on that front, Rod and Tyson, feel free to jump in. How are you guys thinking about networking content per rack if most of the infrastructure going forward is for inferencing, which again, I'm being simplistic here, but as you shift from training to inferencing, as more of the CapEx dollars are diverted to that, how do you think about networking content per rack?

Well, if I understand the question correctly, I mean, I think that when we look at our product set and we look at like the experience we have of high-density networking in general, it's kind of replicating itself now in just a different deployment model, right? So if you're talking about inference at the Edge, kind of complete package model, compute co-located with storage co-located with network and then the need to be able to pull from disparate data sources, provide security over the top, I mean, in many respects, it does mirror some of the common patterns of the kind of age of the Internet and the cloud in terms of what the demands are. It's just a lot more density, a lot more demanding, a lot less jitter tolerant, latency tolerant.

And so we've had a lot of conversations. And when I joined Arista, within the first couple of weeks, having conversations about the importance of like the rack as the product. And I think if you turn around and you look at the heritage on our largest chassis, the 7800s, there's a lot of technology that slots in very nicely for building these kind of co-engineered, highly integrated networking systems where the network is a piece of the story. And even with things like our CloudVision and APIs of our software, it lends itself very well toward automation and giving customers tools to be able to deploy these things, manage them, monitor the workloads, maintain them, security patch them, identify vulnerabilities to kind of help with partners and some of the other integrations that we have.

So I think the rack scale networking becomes a logical extension in the moving forward for us. And I think that's true in scale-up domain as well, not just inference at the Edge.

Let me just pause here and see if any questions in the audience. If you have a question, you can raise your hand and we'll get a mic over to you.

Okay. So maybe just continuing on then. One of the things that we've seen more recently is this thesis that's around agentic AI finally being a catalyst around enterprise customers, modernizing both their data centers and campus. Just, one, what -- how are you thinking about that overall sort of thesis? And do you -- are you seeing any evidence of it yet within your discussions with customers?

I think we're seeing a lot of vertical activity around AI and the enterprise for specific use cases, could be health care, financial, a lot of anticipation about agentic AI. I do think it's affecting people's forward-looking decisions, especially around campus and the Edge. Maybe they would have sweat the assets before. Maybe they're leaning in more to higher speeds and higher performance WiFi 7. But I think in terms of broad-based agentic AI, it's not really happening today. But I think it is people thinking about how it will in the future.

One piece that I think will be important when that day comes is you're going to lose a lot of visibility into what's happening with applications. And when we saw the transition to the client server, there was a lot of consternation about how you would monitor performance of applications. In this world, there will not be a lot of visibility. I think there's a unique opportunity in the network with network observability and the observability architecture we put in to EOS and CloudVision to really get a viewpoint into the topology and activity inside the network that should be an advantage.

I mean the other thing I'd say just as an anecdote, the silly anecdote maybe, but I've got an agent running at home and the thing is actively marketing Arista networking gear to me because I basically told it, "Look, I'd like you to be able to manage my network." It said, "Well, the stuff you've got not great. I said, "Well, what should I get?" It said, "Well, you really should get Arista, but unfortunately, it's too expensive because it's enterprise gear." And I said, "Well, I have a discount?" So that's a silly example, but when you get into enterprises and they realize that our API is so rich and broad, that is going, I think, to sort of start selling itself as they begin to use agents to manage their networks, and that's inevitable, I think.

And we have our own AVA technology we built on top of CloudVision and NetDB to help customers assist in the build out of their networks and visibility as well.

Before we run out of time, maybe just to hit a couple of topics that are of interest to everyone, XPO. You now have, I think, 100 vendor endorsements, [indiscernible] compared it to OSFP in terms of the run that it could have. How should we think about XPO? What it means for Arista economically in the sense that, yes, you enable a new standard in itself, but how does it play into the revenue opportunity for Arista?

We do sell optics that are Arista optics, Arista-branded optics we sell, but we do also enable our -- especially our cloud and hyperscale customers to procure their own optics. So there is some economic piece around the optic itself, but system readiness is key for us. We invested in the OSFP form factor and the MSA I think back in the 100-gig days anticipating 400-gig. We saw some adoption at 400-gig, but it really became mandatory and a better cooling and thermal dynamic in the 800-gig range. And I would say our market share gains that we made and our competitive differentiation would not have been possible without the OSFP. And I think we'll see XPO in sort of the 1.6 begin to be adopted, but to achieve the density, I don't think you'll be able to achieve it at 3.2 without it. I think you have some kind of use cases where it could be an advantage...

Yes, I think that's right. I mean I expect a similar kind of adoption uptake and 1.6T will be the kind of early adoption, but I think the modularity is really great here. You're going to get the density and power savings immediately, power efficiency out of it, but the ability to build a configuration on the fly or specify it to meet exactly what you deploy, if you've got a mix on a DCI use case where you've got ZR optics and you need to half load a system with ZR and you need the other half to be FR MDR internal-facing optics, you can do that very easily with an XPO kind of at deployment, at run time across a diverse supply chain ecosystem. And then you've got field replaceability for reliability and maintenance in the field. So there's going to be some use cases I think that will evolve pretty quickly where you need these mixed modalities of optics where XPO will play quite nicely. And then following on to it, obviously, we are heavily focused on XPO.

You asked about XPO, but we're also invested in CPO and we have a belief that a lot of the work we're doing around modularity, modularity to the optical engine, some of the manufacturing techniques that are being done and XPO can actually apply directly into CPO as well. It will be hard to ever achieve field replaceability because these optical engines are just super sensitive to contamination. They're super brittle. If you break something in the field, you are boing to break the whole switch. And so that's going to be difficult. But a model whereby you can replace the switch, have it serviced and then repaired and brought back into service later is much better than some of the early CPO stuff where everything is really manufactured, sautered down together at run time, it's a complex manufacturing process, yields are lower, that affects costs and then there's no reparability for it whatsoever.

So we think these 2 things will play very nicely in the ecosystem together, XPO and CPO. We just think some of the challenges that customers have around density and speeds and feeds are going to dictate that the XPO -- something get there a little sooner and the XPO will come.

XPO is an example of how we stay on the front edge of the learning curve as well because we're always -- it's such a geeky engineering-led company, we're always trying to solve problems for customers. So we're aware probably in advance of just about anybody else in networking what options are coming down the road because we're codeveloping things. So we don't make mistakes strategically thinking that maybe CPO is the only option. And there's others in the industry that bet the ranch on CPO not realizing there're other options maybe that will come along.

So we're able to distribute our risk across different technologies because we're on the front edge of the learning curve, and that's a really important thing to understand about Arista.

Okay. Maybe just while we wrap up, can you just dive into that a bit because I think there's a broader perception that Arista is delayed in terms of a CPO solution, right? Can you just dive a bit more into what are you seeing from your customers today? And if you were to put time lines around XPO versus CPO, where would you look to intersect the market with an XPO solution? What time line would you expect to intersect the CPO market as well? Or how are you thinking about the cadence of when customers start to adopt these?

I think the vision of CPO really recognized the law of physics where the connector and the chip they're closer together because you just couldn't span the distance and the opportunity to save power by putting -- not duplicating DSPs in your switching chip and in the optics. The problem has been mix and match capability of different optics as well as if an optic breaks, now you're replacing this very expensive switch part. So what we've been able to do working with the industry and the ecosystem is mitigate those downsides with the OSFP and XPO. And eventually, we believe there will have to be a CPO-like form factor, but the thing we're working is to make it really interoperable with multi-vendors and an ecosystem type of approach.

So as the power goes up, if you get past 3.2, there'll probably be some inevitability for the beginning of CPO in a more broad-based environment. I think you'll start to see some of that also in some deployments in the next couple of years as well, the beginning of it.

Yes. I think you'll see some uptake on CPO early. I mean, like Rod said, some people are betting the farm on it, betting the ranch on it. They're going to be very aggressive in trying to push it out and inevitably, there will be some adoption, but it's really well suited for certain use cases, a lot of high-density network traffic. So scale up, scale out to some extent plays pretty well, but I think where you're going to really see material adoption is when you start to get some of these other things that customers really want. They want the serviceability, they want the optionality and then the economics kind of fall behind it.

And like Rod said, some of that geekiness to us, like it's accretive, right? Our evolution of our thinking on CPO is because a lot of the work on the XPO is a pathfinder to say, "No, you can package these optical engines up into a meaningful way. You can use an interposer to interconnect those to the silicon. You can still use that silicon kind of instead of a DSP use the SerDes for driving all that signal." And now you can actually imagine a world that becomes, from a manufacturing perspective, easier to stack up as you kind of work up through that L10 assembly as well. So kind of what I would expect to see for us broadly in the industry is probably XPO really takes off '28, some early adoption may be late '27, and CPO behind it. There will be some earlier CPO deployments on that for sure. They'll kind of run neck and neck to some extent.

Great. I will wrap it up there, but thank you for coming to the conference. Thank you to the audience as well.

Thanks for having us.

Hello, and welcome to Needham's 21st Annual Technology, Media & Consumer Conference. I'm Ryan Koontz. I'm Really excited to host Arista Networks here today joined by CFO, Chantelle Breithaupt; and John McCool, SVP as well as Rudy Araujo, VP of IR. So welcome guys. How are you going?

Great. Thank you. Thanks for having us again.

Excellent. Super Well, Chantelle, let's start with your excellent quarter you guys had. Can you maybe walk us through how you felt about the results, obviously, beating expectations, and what's some of the kind of key demand drivers in your first quarter were?

Yes. Thank you. We were very excited as a company to report our results. I'm very proud of them as a team. We're very pleased with the 35% revenue growth. And if you take that, Ryan, with the change in deferred revenue, it's actually 54% of revenue forward-looking kind of growth, so we're very excited by that, right? We raised FY '26 again to the $11.5 billion, twice in the last two sessions with you guys raised the year, which is great. And if you guys go look, I encourage you all on the call to go look at our latest earnings deck where we actually also raised our 3-year CAGR outlook to be 20-plus percent. So a lot of great news, a lot of great momentum. So super excited. As Jayshree said, we've never seen more demand than we see at this time.

And we're really encouraged. We're encouraged by the progress we see in AI and the adoption of our 800-gig Etherlink portfolio. We're proud to be winning new logos across all the sectors, all our customer sectors. And the proof of concepts for Campus are really working well. We have a high win rate when we can get in there and look at the Campus where we're only 3% market share today. EPS growth, I think, was stellar. So sum it all up, we're super excited and feeling the momentum.

Excellent. And within the quarter, hyperscalers, your big customer is obviously a big contributor there. Some of your Neoclouds, I'm sure. Can maybe walk us through your thoughts about how your different customer segments contributed in Q1?

Yes. I think that we said it was a really great quarter across the board, but in the sense that we saw some really strong performance from the AI specialty provider segment, which, of course, is across the AI portfolio. So I think that's continuing to do well. And so from that perspective, I think all of those segments are showing really great signs for the year.

Super. Yes, you mentioned the nice step-up in deferred. I think it was up 100% year-over-year, it's just incredible. I mean, can you remind us again what's going into deferred, and what's driving that acceleration here for investors that they should be paying attention to?

Yes. I think it's really important for investors to understand and to go look at the earnings deck because we have some analysis and trending, which I think helpful to position where deferred is for Arista over time. But just to remind, what goes into deferred, so we talked about the $3.5 billion of AI revenue in the P&L this year. But most of what's sitting in deferred is AI use case and product. And so you have to look at both combined to look at the AI demand that we're seeing across the board. And it's not that we just put it in once and it's aged over 2 years, things come in and out of the deferred into the P&L. So it's rotating, it's refreshing.

And so I think from that perspective, it's important to look at the earnings deck pages we have. But it's a sign of growth and momentum in the sense of the AI demand that we're seeing.

It's clear, incredible demand environment right now for yourselves and a lot of your peers and your ecosystem partners, I'm sure.

And with regards to your full year, raising that to 28%, what were some of the puts and takes there? Coming out of the quarter, I think some of the investors were maybe a little disappointed that you guys didn't pull the second half up as much. And how would you characterize your constraints there on your ability to raise your full year a little more relative to your supply environment?

Yes. I don't think the year guide was in the sense of necessarily tying it to the supply environment for this year. I think -- and John will take us through probably a little bit during your questions in the sense of the supply environment. It's a when not if to us. I think you have to take our -- I think I would take it the inverse way, Arista raising twice, and we never assume 100% of everything is going to work in our guidance philosophy. So I would take it as, hey, Chantelle and Jayshree, raised twice in the last 2 quarters, and we're only in May. So let's keep watching the future quarters. And if everything can fall into place, we'll see where we can get to. I think that's how I would take it versus always trying to meet what people expect from us from a guidance perspective. That's not new. So we...

What do we get that? Trying to be conservative as you guys are, and beat and raise, we like that.

If I have to choose a philosophy, I would choose that one.

For sure. And John, how would you characterize the supply environment and some of the puts and takes, and what you guys have been successful in doing. You obviously tie up a lot of capital in terms of commitments with your strategic big partners like Broadcom, kind of walk us through your thoughts are on some of the things that are going well and some of the challenges you're feeling right now on supply.

Sure. Let me start with the going well. If you think about Chantelle's comments on deferred, the actual supply chain team had to deliver both the deferred revenue plus the revenue that was recognized. So 54% growth year after year. So we have a lot of busy folks and our suppliers are very eager to support us to fill this demand. That said, the entire supply chain environment with the AI demand is really pressing capacity on foundries. First, we saw that with memory and how that played through. There's a lot more fabs with memory on silicon, there's some concentration in those fab cycles. So that's what we're up against is an environment that's really booming across the board and really having to drive that and to turn it into finished goods and ship. So we're really comfortable with our execution so far and we'll continue to drive it.

In regards to your updated guidance, do you feel like you have everything you need in place in terms of supply chain to execute on the guide and hopefully, chase some upside there?

We're very comfortable with the guide on both margin and revenue, for sure.

Excellent. And can you maybe walk us through how you use purchase commitments to really lock in that supply, your purchase commitments were up pretty strong, is that around memory?

Yes. I mean that's -- it's across the board, but in the areas where there are constraints, specifically, as we look ahead into 2027, and what we're seeing from the demand environment, but it also helps us in short term, get very tighter with those suppliers in terms of our demand today.

Yes. And the only thing I would add, John, to your comments is that raised to $8.9 billion, it is across everything. The majority, I would say, is chip related, and it's a 52-week lead time, right, John? So we're leaning into your point into '27. So getting ahead of making sure that, that's sorted for what we need to deliver in '27.

TSMC guys are going to be pretty busy. I think...

I think they've been busy for a while.

Yes. Great. Well, maybe shifting to customers and what's happening in the AI domain. It's been a huge success story for you. I remember back a couple of years, a lot of questions, what was Arista's role in the AI back end. And you've certainly proving that out, and you're knocking down some great wins. I think in the quarter, you announced that your fourth AI customer had moved their back end from InfiniBand over to Ethernet. What brought that customer over? And how do you feel about that going forward, all of your AI accounts there?

It was the same trend we've seen on other ones. That particular customer was kind of early on had made some investments in InfiniBand and the full NVIDIA stack. But the compelling reason to move to Ethernet is multi-vendor supported, agnostic to the endpoint. So NVIDIA GPU, AMD, something you build on your own inference engine. Same capability as your front-end network, your back-end networks, so the operational simplicity around it.

And I would just add, you're seeing the same dynamic around NVLink and ESUN, starting to come up the industry rally around that and while that's not a near-term thing in terms of revenue, I think that also has bearing us in terms of the architecture going forward.

Super interesting. Wow. Maybe Chantelle talking about price a little bit. I think you announced some price changes to offset the memory costs. How is that flowing through the income statement here relative to price changes?

Yes. I think that -- back to John's point, I think the supply chain team has done great work over the last few quarters. And you've seen various companies talk about different quarters in the last 3 to 4 where memory has been in their conversation. Our philosophy or our approach and strategy was to understand the market, understand where we thought the pricing was going to go a cost to us. And the kind of the added measure twice, cut once. So we want to be sure we had a pretty good line of sight and visibility into what the cost was going to be for us for the next few quarters.

And so with that, Ryan, we did a price increase, which customers never love, but at least it was a well-known topic. Our goal was to be margin neutral over the time of the backlog converting to new orders. And so I would say that kept us in our 62% to 64% gross margin guide, which we've been talking about for, I think, 3 or 4 quarters now. So I'm super excited. We've been able to hold it, through it. We've earned the value and trust of our customers to have those commercial conversations. So we're pleased with the result, but never like to deliver a price increase to the customer. So I think margin neutral is landed. And that's allowed us to keep our guide.

Sure. I mean everyone in the hardware industry is feeling that one pretty hard. And are you guys exposed to both DDR4 and DDR5 across the portfolio?

Yes, not the same equal weighting, but yes, to both technically. Yes.

Great. As you think about your AI revenue bogey here of $3.5 billion, which is raised from $3.25 billion. That counts -- does that counts your 4 large customers there and not others that you've added -- new logos that you add?

Yes. I think that $3.5 billion, the way I like to look at it as you look at it as a percentage of the $11.5 billion, we're talking 30% of our revenue not too many years into AI totally is a pretty good win rate. I think that -- but it covers more than the 4 customers. I think that you heard a couple of quarters back, you could technically count about 100 customers across to Neocloud, some large enterprise, the 4 we talked about. The 4 initial pilots were just to take you along the journey with us as investors and the community, how it was going with the larger ones, but it covers AI, we think, is the predominant use case. So we're proud to work with some of the largest customers, with some of the smaller ones that are starting to get into their inference conversation.

I'd like to explore that, if we could. Just discussing some of the Neoclouds, what the Neocloud kind of procurement model, how that might differ from a hyperscaler type model? And then maybe talk about inference, could you guys dive into that?

Sure. Yes, I can probably jump in on that one, Ryan. So I think the Neoclouds have kind of evolved a little bit, right? Like I think when they started, A lot of it was looking for a rinse and repeat kind of reference architecture kind of model, frankly, they needed allocations of compute -- bound them on networking decisions, right?

I think what they realized is they were all starting to look the same, right? So how do you differentiate in the crowded Neocloud market in terms of what you bring to the table. And I think what they realized is the network is actually pretty critical to that differentiation, right, because the network can mean the difference between job completion times, taking longer or shorter, it can mean the difference between power utilization being higher or lower. It could be the difference between time to first token and when we start talking about inferencing, et cetera.

So what we're starting to find now is that they are actually realizing that they can't just be bound into these agreements based on what's good for compute because having the best-in-class compute is no use if you've got a substandard network, right? So that is opening up the market for sure. I think the other thing is they are definitely not buying at the same levels as the largest hyperscalers, right? So that's perhaps stating the obvious.

But they are also the folks that need a little bit more handholding, right? They don't have the experience necessarily of having built these large cloud networks, et cetera. So we're also seeing a higher attach with CloudVision, for instance, and with our Op capabilities that gives you AI Ops kind of visibility into it. So that's kind of a little bit of an interesting dynamic there relative to the hyperscalers.

Super interesting. And maybe to follow that up, you guys have talked about both scale across as well as scale out kind of that dynamic, can you maybe unpack that for us a little bit and where you've come from and how you see the market evolving in the back end there for you in terms of opportunity and what's driving your revenue?

Yes. I think we -- it's interesting to us because we saw a similar dynamic in the beginning of cloud. Once we were able to connect all the servers in the data center on a 2-tier spine leaf architecture the question is how do you expand because I don't have the physical capacity in this data center for more CPUs. Now it's GPUs. So scale across is becoming kind of the next generation of the leaf spine architecture and the Universal Spine to interconnect. So we see all different use cases, but specifically where you want one logical AI cluster across multiple physical instances.

And scale across sounds like it's in the pretty early stages of build-out. Is that right?

I would say relative to scale out. And I think in the sense of -- and I know Rudy, you're going to jump in. This is a very exciting topic for us. I think -- so the only thing I would say is that it's fairly new, but you can see how it might be required because a lot of this is when you need these kind of federated space land access to power cooling scenarios, and I think that's part of what's driving that need. But Rudy, I know you want to take that on.

Yes, I was going to say exactly that. And the other side of that point is, as you start talking about inferencing, Ryan, you brought this up. Inferencing is increasingly like how do I get as close to the edge as possible, right? Because if you're sitting in New York right now and you're asking -- you're trying -- you've got an agent running on your device and you're trying to interact with the model, you don't want to be waiting seconds [indiscernible] over time. And so that's the other thing that's going to drive, I think, scale across. So we're very excited about it, partly also because it's a very unique product set that it takes to be successful there, right?

And we've shown success there. We've got the products frankly, a lot of our competitors that we would run into and scale out don't have the product set to compete and scale across, right? So I think we feel very good about it, but it is relatively early to the point the Chantelle and John was making.

Excellent. Yes, that's great. And unless we forget about good old cloud, front-end cloud. And I think the back end has pretty much sucked all the thought out of the room and the attention. But maybe tell us what's happening in the front-end networks these days. That's been your core business, where you've been such a dominant leader for so long. How is the front-end changing to adapt to some of the new AI requirements? And what are you seeing happening in the boring old cloud business?

Yes. I mean it's funny, right? I mean, I forgot -- at least in the analyst world or in the world it is. I mean, for us, it's certainly a tremendously important piece of the puzzle, right? From an upgrade cycle perspective, if I can call it that, most customers in the front end are still in the 400-gig era, right? At least at the hyperscaler level. Some of them are maybe in the 100-, 200-gig era because frankly, the applications that we're using today are working just fine, right? I mean, we're on a web conference, we're all coming in nice and clear, going over those 200-, 400-gig networks.

It is triggering a cycle, especially as this agentic traffic pattern starts to become more commonplace, it is going to trigger that cycle. Probably next year is where you start to see the front-end networks kind of get upgraded. I mean we're certainly having conversations right now, it's in maybe more planning phases right now. But maybe next year is when you start to see the 800-gig kind of upgrade just as the AI clusters start to go into the 1.6 era, right? So there's probably a little generational gap between the front end and the back end kind of naturally if you would.

The other thing, by the way, is again, inferencing is having a huge impact there. And frankly, we didn't touch on this, but inferencing is also having an impact and the agentic is also having an impact on the enterprise side, and I think we can talk about that as well. I know it's not front end, but I just wanted to kind of get a...

I'd like to hear that on soon.

Yes.

That's great, Rudy. Yes. On the enterprise side, you're having these early discussions, I'm sure with big Fortune 50 types and financials. And I can imagine those are the leaders leaning in here. Like where are those discussions with you about architecture and build-out? Who's going to hold their hand to go do these sorts of things? I mean, do you think there are traditional guys like your competitors that are maybe more deeper entrenched in enterprise that are going to get their fair share there? How do you think about the enterprise kind of AI build-out to complement where they already have quite a bit of private cloud out there, I'm sure, where you guys are very strong.

Yes. I think one thing I'll add, or at least start with and the team can chime in. I think one thing that we've heard from some of the larger customers because part of that $3.5 billion is with enterprise customers, as we mentioned. So part of what they are starting to think about as they go through their refresh cycles as they think about new data center builds, Campus and data center, to be fair, is what is their AI landscape, what is their AI goal in the company. And one thing that we're finding is really great in the conversations when you can have one operating system like EOS across all of those components, it's super easy to have agentic AI sit on top of that because you're only having to hook into one operating system.

You can imagine having an agentic AI kind of portfolio where you're trying to go over different operating systems, not as easy to hook in, not as easy to be ubiquitous experience. I think that's a great -- like Ken thought about that maybe 20 years ago, not sure, but he designed something perfectly built for it. That's the things we hear from customers. We're hearing them pull in their campus refresh earlier to try to get into this get ready for at the edge agentic AI inference. Those are some of the things we're hearing. But Rudy or John, anything you want to add?

Yes. I think Chantelle, you hit the -- maybe the most important thing I hear from customers, right, they're realizing that AI within the enterprise is not just a Campus issue. It's not just a data center issue. It goes across the branch, the Campus. To Chantelle's point, that unified operating platform across all of those is really something that's exciting. It's frankly the other thing they're asking us and we've heavily invested in is what is our AI strategy for -- AI for networking, right? Not just we've talked a lot about AI, but AI for networking and AI for Ops. And we've continued to invest there in AVA, which is our Autonomous Virtual Assist, driving better outcomes, if you will, for customers and being able to do everything from root cause analysis, to helping them automate as much of the network operations as they like, right? Like this is not about, hey, you don't need a network operator anymore. It's about how can we augment what the network operator is doing and make their life more efficient, if you will.

Really great, Rudy. Let's shift gears to one of my favorite topics coming out of OFC, which was the XPO announcement. And I went in very excited to hear about it because I hadn't done a ton of work on it myself. I was probably a little behind. But wow, I walked away from OFC and saw just the broad industry endorsement and was so impressed. So can you maybe walk us through kind of how you got there, how you built such strong support and what it means to Arista for that to be adopted as an industry standard?

We have a very passionate founder, Andy Bechtolsheim, who...

Yes, you do.

Over many decades, has really led the definition of many MSAs working with these partners. It goes way back in terms of his development. The most recent before this was OSFP. And we anticipated that at some point, the thermal dissipation would be such that the conventional state-of-the-art would not be able to contain that. And that really was an enabler to the products you see today and our leadership in those deployments. And we're seeing the same thing happen as we go to 1.6T and beyond. The OSFP form factor was great, but won't be able to carry the industry on the next generation.

So he's been working with the team here at Arista and the optics team with those partners and building it out and we engage with them in testing and definition. So it's been a real great collaboration with the industry.

Yes. It's a super cool solution. Go ahead, Chantelle.

No, no. Okay. I don't want to stop you from saying it's super cool. What were you going to say?

No. Go ahead.

But I think that we're very proud because it's industry-leading, right? But as far as what it means for us, it's open to the industry and may all people play competitively in it. But I think for us, again, it's another thing where we've been kind of ready. We've got our product portfolio already thinking about it for the next generation of things. So I think it just place us well to be ready for something that the whole industry, hopefully, and our customers, more importantly, will benefit from for years to come, right? And so...

For sure. Yes.

The other aspect of this that sometimes I think doesn't get fully absorbed is the front panel density that this can add, right? So being able to shrink those racks opens up a whole bunch of other scale-up technologies from RF to micro LEDs, et cetera, that are far more power efficient, right? So it opens up, I think, an entirely somewhat tangential benefit but a super important benefit as these clusters start to get more and more dense. And the front panel density was becoming a limiting factor, right?

Not to forget, by the way, the sheer amount of sheet metal, less sheet metal that you need and the structural cost that, frankly, aren't paying the bills, right? Like they just deadweight, if you will.

Yes. I think the stat we would throw out there is 40-plus percent footprint reduction, just to give the audience an idea of what we're talking about.

Yes. And so really, you're saying not just for scale out, but there are other applications for that same technology that you can embed on that sled that XPO...

Yes. Scale up is probably the most interesting one because getting to the point where it was as easy definition, right? If you're within the rack and scale up, if you go outside the rack and scale up, well, we realized that we need more compute in that scale-up domain. And so now we're thinking of ways to go across multiple racks, but still stay within that coherent memory kind of scale-up the domain. Well, technologies like this are going to enable that, right, because it gives you a lower power way to interconnect these across a larger physical distance, where copper is really going to struggle, right?

So not only is there a direct benefit from an optical perspective, but I think it opens up other avenues. And like everything Andy always does, right, it's a completely open standard based, there's nothing proprietary, there's no like, hey, you have to have Arista to get this to work. But I think to Chantelle's point, it really continues to show the thought leadership that we bring to the table and how we move the industry forward with these open standards.

Super cool. So when do we start seeing products in customers' hands and supply chain start to ramp? What's the time frame that this starts to impact the industry?

So I think this is really something that will probably be most impactful, in the 3.2T era, 1.6T, you're still going to continue to see. And frankly, I think if Andy was here, he'd tell you, OSFP is not going away, right? There is a vast majority of optics out there for the foreseeable future will be OSFP. Especially when you count the enterprise and things like that. But I think for XPO specifically, you'll start to see the first products, I think, come out next year and really very large ramps in that 3.2 terabit era, where its value is much more impactful than to John's point, right, where OSFP would struggle.

Right. And the only other thing I would add to that is, I think about a quarter ago, so everyone thought 3.2T was when we'd have to go to CPO. And I think this shows that now we have a whole longevity even at 3.2, that's not required.

Exactly. Great. Maybe shifting to the Neocloud. I know we touched on them already. But you talked about a more consultative sale. Can you maybe unpack that a little bit for us in terms of what your role is in working with them, they're not probably as deep and sophisticated as some of these hyperscalers have been doing this for decades. So how is Arista's role evolving with the Neoclouds and AI specialists?

Yes, I can start and the group can chime in. So I think -- I personally think Neoclouds is a fascinating segment. Every one of them is different and a pleasure to work with. But they all -- they come to us differently. Generally, they come to us because they know we have the bigger cloud experience. So they would like more of that like what Rudy and John described. But there are different scenarios that we come into it. There's a scenario where the team has experience, and they know us and it's a best-of-breed open conversation, high win rate there because everything -- our portfolio of Etherlink suits that very well and all the things that Rudy mentioned.

Then there's the example like what Ken Duda mentioned in our earnings call, where the first try of it with the team, team capable, but in a different scenario. They went with a different solution. And now they've come to us because they realized the capabilities required of their incumbent technology and architecture didn't serve their scale-out needs. And so Ken Duda did a very good job, I think, articulating that scenario, we see those. And we see things that when people feel emboldened to go to different XPU vendors they come to us because they know we're agnostic to the XPU. So we see, they come at us from different angles, but we are known as being a great provider to them for their AI needs.

I don't know, Rudy and John, if there's anything you want to add, but...

Yes. I mean I think in terms of the selling process, the only I would add is, look what's done well for Arista is this deep engineering to engineering partnership, right? Like so having our really folks that are working on some of these largest networks be in that consultative selling process with the Neocloud is something that they appreciate because, frankly, they are breaking new ground. And they're trying to do this at kind of the speed of light, so to speak, right? What normally might have taken a year or 2 years to ramp, you don't have that luxury anymore.

The only other thing I'd add, and I'll tie this back to your previous question about optics, right? Like one of the things that they appreciate about working with us is we don't lock them into, well, if you want to do this, you have to go down the CPO route, right? Like we still give them that optionality. If they want to go down CPO, we're thinking about open CPO and things of that nature, XPO is obviously there. LPO is an option, traditional OSFP fully retimed, like whatever -- they don't feel as locked in, and I think that's something that they're really beginning to appreciate because as I was saying earlier, ultimately, they've got to bring dollars and cents in the door and from their end customers. And to be able to do that, they need to be able to differentiate from the Neocloud down the street, right? And how do they do that? They're all running the exact same architecture, if you will.

Sure. Makes sense. I want to go back and touch on agentic. It's going to come up more and more and more. I think it's really starting to impact the company's core business with all the different agents that are being rolled out. How is that affecting the architecture of your customers? We hear about more CPU content, locating CPUs closer to GPU clusters. I mean, how does this affect Arista's demand equation and the conversations you're having with customers in terms of agentic infrastructure?

Do you guys want to start? Or do you want to start?

Yes, I can start. So Chantelle kind of touched on this a little bit earlier, right? Like people are starting to think about, okay, what does this new bandwidth pattern on the -- look like, right? In our traditional world, maybe it's a little bit more bursty, right? You go to a ChatGPT, kind of more chatbot, kind of a world of LLM or generative AI. It is still bursty, but maybe the burst are slightly bigger, if I can use that term. You get to an agentic thing, and these things are talking to each other all the time, right? So how do you kind of manage through that process?

So as Chantelle had touched on that, right, WiFi 7 is becoming maybe a sooner cycle than you normally would have seen with these WiFi migrations. They're also thinking about things like what does that mean from a power Ethernet perspective, right? Because now you've got all these smart devices that are all across your environment that are also becoming agents in themselves. So how do you enable that? How do you enable them to be securely connected to your network, right? So Zero Trust Networking is another aspect to the conversation that they're having.

And then frankly, kind of the bread and butter stuff around things like routing and encryption on the wire and multi-tenancy, like stuff that, frankly, I think most people would think is boring until maybe 6 months a year ago, but it's becoming super important now. And again, I'll repeat what I said earlier, we're one of the few folks that has the products to play in that space, right? So we like our shot as we get into that. The competitive -- it's not that there's no competitors, but it is a different competitive environment than I think you see with maybe scale out, for instance.

And I think that -- sorry, go ahead, John.

Just one of those boring parts that Rudy has talked about that's baked into the architecture. Whenever we see like a mission-critical application, we see a thrust in those customers looking at observability, what's happening on my network. So now you can imagine all these agentic communications, this new type of workload. What kind of visibility can you provide, customers can see what's actually going on. That's going to be pretty important as well.

Is that where your telemetry kind of has a lot to offer?

Absolutely, not just the telemetry itself, but the architecture of the state-based architecture and be able to stream information is going to be critical.

Yes. That's a big differentiator for you guys. I've heard a lot about that. With regards to 1.6T coming, how are you thinking that the long-awaited Tomahawk 6, how is that going to impact your mix and demand? And is this just a normal generation? Or does this bring any kind of accelerators to the demand equation to keep up with all this bandwidth?

Well, I think we're not preannouncing anything, just to be clear in the conversation the way you asked the question, but I think you could count on us to be ready when the cycle is there to be ready with the great products we usually do. So take that as we'll be ready when the market is ready and everything comes together from an ecosystem perspective. I think -- I don't know if there's anything there, Rudy, or John, we talked about in the sense of accelerating at this time. Clearly, there's a demand in the portfolio in the customer set. But Rudy, anything you want to add?

Yes. I mean I guess just one interesting data point, right? Like I think we released 100 gig products. I mean John will probably keep honest here, in 2019, I think, give or take. The 800-gig products came out in 2024, right? So that what, 5 years? It's not going to take 5 years to get to. I know we're preannouncing product, but I can tell you it's not going to be 5 years to get to 1.6T, right? And people are already talking about 3.2T. So in that sense, the pace of innovation is absolutely rapid, right? I don't think it's anything we've seen in the world before. And frankly, that's why when Jayshree says, look, this demand environment is nothing like I've ever seen before. And by the way, she's seen a lot right in this industry. That's the say probably.

But in terms of how customers think about it, it is the next generation of networking. The uniqueness of course, is the cooling infrastructure is changing, right? Like I want to see a mix of air cool and liquid cool, right? So that's, I think, an interesting dynamic that customers are still kind of trying to get their hands around because this is breaking new ground for everyone, right? And it's part of the reason why Chantelle talked about new use cases, new products, et cetera, like this is some of that complexity that comes in, right? It's not just about can we ship the product out the door. It's can the customer also be able to absorb that and get value out of it, right? And that's where I think we continue to partner. It's a model that's worked really well for us, and we see no reason to change from that, right?

Yes, the shift to liquid cool data centers. I mean, I didn't see this coming. The mechanical engineering will be so cool again.

It's back.

It is. Let me just wrap it up here. But let's talk briefly about Campus and your progress in Campus and WiFi a little. Can we touch on that briefly?

Yes, I would love to. I think that if you look at -- I think last year was our first real external kind of accountability model, and we hit that revenue of $800 million. We raised the target this year to $1.25 billion. So 55% growth for ourselves with you guys to hold ourselves accountable. Super excited. You've heard others talk about, there's a great refresh cycle happening in the next couple of years. We're definitely participating. We're winning in campus, not even being in the data center yet, which validates our portfolio. Our proof of concepts are very well received. I think that -- so we're just -- we're super excited with campus. Our portfolio is there to meet their needs, including this agentic AI conversation.

Rudy, anything you wanted to add on the -- or John? Because I know, we're out of time.

That 55% in context, right? I think it's a market that's growing single digits. We are starting from a low base. I mean our share is probably in the 3%, 4%, 5% range today. But I mean, that is just tremendous growth. So I think just as much as we're excited about the AI opportunity, I think the Campus opportunity is incredibly exciting, especially because there's far more customers building Campuses than there are customers building AI, right? So it's a different selling motion. It's a little bit slower of a ramp, et cetera. But it is a long game, and we're in it for sure.

That is great. Well, super. I mean, I really appreciate you guys joining today. Any last comments you wanted to make Chantelle to investors just wrapping up where Arista is delivering?

We raised our year twice in the last 2 quarters. We had 55% across the P&L in deferred revenue, exceeded EPS expectations, and so we'll continue to deliver value to you guys. And hopefully, you're as excited as we are in the demand that we've pervaded to you today.

For sure. Well, thanks for joining. Really appreciate it.

Thank you. Have a good day.

Bye.

Bye.

Welcome to the First Quarter 2026 Arista Networks Financial Results Earnings Conference Call.

[Operator Instructions]

As a reminder, this conference is being recorded and will be available for replay from the Investor Relations section on the Arista website following this call. Mr. Rudolph Araujo, Arista's Head of Investor Advocacy, you may begin.

Thank you, Regina. Good afternoon, everyone, and thank you for joining us. With me on today's call are Jayshree Ullal, Arista Networks Chairperson and Chief Executive Officer; and Chantelle Breithaupt, Arista's Chief Financial Officer.

This afternoon, Arista Networks issued a press release announcing its fiscal first quarter results for the period ending March 31, 2026. If you want a copy of this release, you can find it on our website. During the course of this conference call, Arista Networks management will make forward-looking statements, including those relating to our financial outlook for the second quarter of the 2026 fiscal year, longer-term business model and financial outlook for 2026 and beyond, our total addressable market and strategy for addressing these market opportunities, including AI inventory management, lead times and product innovation, which are subject to the risks and uncertainties that we discuss in detail in our documents filed with the SEC, specifically in our most recent Form 10-Q and Form 10-K and which could cause actual results to differ materially from those anticipated by these statements.

These forward-looking statements apply as of today, and you should not rely on them as representing our views in the future. We undertake no obligation to update these statements after this call. This analysis of our Q1 results and our guidance for Q2 2026 is based on non-GAAP and excludes stock-based compensation expense, intangible asset amortization, gains, losses on strategic investments and the income tax effect of these non-GAAP exclusions, including the recognition of direct access tax benefits associated with stock-based awards. A full reconciliation of our selected GAAP to non-GAAP results is provided in our earnings release.

With that, I will turn the call over to Jayshree.

Thank you, Rudy, and welcome, everyone, to our first quarter 2020 earnings call. Arista has experienced significant velocity in all our sectors in Q1 and are now commanding the #1 market share in high-speed switching in the greater than 10 gigabit Ethernet category. With that, we have overtaken many incumbent vendors according to major market analysts for 2025. Our cloud and AI networking strategy for diverse AI accelerators continues to gain traction. Unlike typical workloads, AI workflow patterns can be long-lived elephant flows or short-lived and simply not predictable. This implies careful attention to performance where a flow can cause [indiscernible] for a long duration of milliseconds. The intensity of a flow can determine the line rate throughput, the shifting traffic patterns to massive flows synchronized to all in all, or all reduce or bursts of collective communication are all important for AI training and inference applications.

I would like to take a moment to review our 3 AI fabric use cases. In scale-up mode, we have familiar technologies such as NVLink and PCIe that have enabled vertical scaling of single compute nodes or REX. The advent of E.SUN Ethernet for scale-up networking specifications allows for increasing or decreasing computing power in a flexible manner with Ethernet to automatically adapt to workload demands. Scale-up will be a new entry for Arista in 2027 and beyond, where we will be working closely with our customers to build AI racks with very fast interconnects for co-packaged copper, CPC, or open co-packaged optics, CPO, as well as supporting collectives and memory acceleration.

Scale-out or horizontal scaling involves adding more machines to a [indiscernible] spine fabric, moving workloads across multiple servers or nodes or even connecting other elements like storage or CPUs. As you scale up [indiscernible] with massive data sets, bottlenecks can be resolved with collective and protocol acceleration at L2, L3, cluster load balancing, all at wire rate. The system must deliver consistent performance without degradation as more nodes participate. Arista is a shining example here with greater than 100 cumulative customers to date in 800 gigabit Ethernet deployments, and we expect the addition of 1.6 [ terabyte ] in 2027 at production scale.

Scale across drives across the cloud and AI as the AI accelerators in a location may need to be distributed to achieve the appropriate bandwidth capacity with the optimal power. As workloads become more complex and more distributed, the bi-sectional bandwidth must scale smoothly to avoid bottlenecks and preserve performance. This demands sophisticated traffic engineering, deep routing, encryption properties and integrated optics based on Arista EOS stack and using Arista's flagship 7800, R3 or R4 series. The 7800 has established itself in this category as the premier scale across choice.

You can see with Arista's accelerated networking strategy and these 3 types of AI fabrics. These are critical to deployment of diverse accelerators and frontier models. Traditional static network topologies with hotspot jitter that slows down job completion time or increases time to first token for inference are all not the way to go. Arista's Ethernet portfolio addresses both the synchronous flows for massive training and the low latency for concurrent swarms of real-time inference in this era of trillions of tokens, terabits of performance and terawatts of power. In 2024, you may recall, we discussed 4 Ethernet-based AI training deployments. And of course, since then, we've expanded and exploded to countless others. This fourth customer from the group has officially moved from InfiniBand to Ethernet at production scale over the last 2 years. The high-speed Ethernet AID spine with flexible air or liquid cooled infrastructure overcomes the physical constraints of power and space for AI workloads.

It results in a low latency distributed AI supercomputer fabric across global regions. What is clear to me and us is our networking progress with data, control and management and multiplanar orchestration is not only central to our AI searching performance, but also important for high-speed optics transmission. At the recent Optical Fiber Conference, Arista unveiled its extended pluggable optics, XPO form factor designed specifically for optics innovations at high speed. Now endorsed by greater than 100 vendors, salient features include record-breaking throughput, delivering 12.8 terabits per pluggable module, unprecedented rack density achieving 204.8 terabits per OCP rack unit, integrated cold plate capable of cooling up to 400 watts power per module and the universality and flexibility across a range of pluggable optics, copper as well as linear halftime our retimed interfaces. A special kudos to Andy Bechtolsheim, Arista's Chief Architect for driving from OSFP 10 years ago to this next-generation XPO, bringing structural improvements in power, footprint and cost reductions. Our enterprise business experienced strong results in Q1 2026, both in data center and campus. Our VeloCloud acquisition is also integrating well into our branch and campus strategy, bringing more distributed enterprise use cases and a new channel motion with managed service providers, MSPs. To share some recent wins, let us hear now from Todd Nightingale and Ken Duda, our Co-Presidents, to delineate our Arista 2.0 Centers of Data Strategy. Over to you.

Thanks, Jayshree. Arista is diversifying this business with new customer acquisitions covering a broad set of use cases, all unified by Arista's EOS stack and its ability to modernize enterprise infrastructure operating models. Our first highlighted win is a new cloud AI network. The customer was constrained by an incumbent white box architecture that simply could not keep pace with the massive scale-out requirements of AI. Arista was selected as a commercially proven and reliable scale-out architecture with unmatched stability of EOS and the ability to connect AMD MI Series X [indiscernible]. Arista's AI leaf and spine Etherlink products were deployed at 800 gigabits to provide the incredible performance, modern AI networks require. The AI fabric was tuned using Arista's cluster load balancing to scale out the thousands of XTUs minimizing hotspots and congestion. On the software side, the customer leveraged AVD, Arista's validated design framework, to automate network provisioning, which both reduces the total cost of ownership, but also provides an easy path to reliable network deployment at scale, where without AVD automation, a small mistake can cause precious days of debugging time. This was a strategic neo-cloud win with large potential for upside growth in an area where we are seeing enormous opportunity and velocity in both new cloud and soften cloud customers.

Our next win is in the service provider sector with a leading regional fiber-to-the-home provider serving hundreds of thousands of subscribers. As subscriber bandwidth demands have surged, this customer realized their legacy routing architecture was too rigid, too brittle and too costly to scale. They needed a solution, which would modernize their next-generation backbone and Internet puring edge. Arista won this upgrade by proving an automation-first approach with a modern operating model, driving operational savings and increased subscriber reliability. On the hardware side, we deployed [indiscernible] 7280 routing platforms using EOS's FLX capabilities, which unlock deep buffering, a rich control playing software stack and full Internet route scale. On the software side, Arista's AVD framework, again, automates router provisioning to reduce the time it takes to turn up services while also reducing errors. Here, we saw great results from our technology partnerships with Palo Alto Networks, ensuring the routing edge integrated securely and seamlessly with our overarching security architecture. And here, Arista's core value proposition of lower operating costs and greater reliability to grow the competitive win. Now I'll hand it off to Todd.

Thanks, Ken. Our third win is in the insurance services sector. Following a year of strategic collaboration, the customer wanted to modernize their infrastructure with a streamlined, automated foundation capable of delivering granular real-time insights to secure and monitor critical applications. Here, observability was truly the key. Arista secured this comprehensive win after executing a flawless proof of concept proving our architecture significantly exceeded operational standards. To achieve deep network observability the customer deployed our R3 series for filter and delivery roles on our monitoring fabric DMS. Additionally, they deploy campus switches to radically simplify out-of-band management. Leveraging rich telemetry capabilities of EOS, the customer unlocked advanced features like VXLAN header stripping and transition to a fully automated declarative operational model.

Our final win is within the manufacturing sector where we're seeing amazing momentum. Here, we have a customer operating more than 100 factory sites globally, servicing consumer, health care, aerospace, defense and AI infrastructure customers. This was a true mission-critical use case and their legacy campus network have become the bottleneck for achieving real 24/7 production. Shifting traffic patterns, manual provisioning and importantly, a lack of visibility and forensics into microbursts and drops for keeping them from achieving their goals. Arista won an extensive bake off against 2 established vendors, both of whom proposed campus design that could not match what Arista delivered, a universal leaf spine campus based on open standards running a single EOS binary across campus, data center and WAN. The Cognitive Campus solution leveraged 100-gig campus spine, high-powered POE leaves and Arista WiFi 7. CloudVision drove provisioning, configuration and life cycle end to end with consistent tooling across the network infrastructure. Here, it really was Arista's modern operating model that drove differentiation in the engagement, hit list production upgrades, latency analyzer for microbes visibility and true packet drop forensics.

The teams were able to significantly reduce production impacting maintenance windows and exposed events that had previously caused lying interruption. In all 4 of these examples, Arista's support team stood out to customers for its best-in-class service, well known for troubleshooting issues with customers long after Arista gear is no longer suspected to be at fault. Arista's modern operating model also played a key role, especially the AVD tooling that Ken mentioned, for architecture, validation and deployment. We're excited about the momentum across the entire enterprise business and especially the diversification that it brings to Arista Thanks, Jayshree.

Thank you, Todd. Thank you, Ken. It was so fantastic to hear of happy customer outcomes. We had another fitting example of that at our Innovate 2026 event here in the headquarter facility held in March. The energy and enthusiasm of our greater than 250 customers who attended was truly [ infectious ] and inspiring. I want to especially give a shout out to Ashwin Kohli and Divia Wagners teams who have already improved our outstanding Net Promoter Score from 87 to 89 ratings translating to a 94% customer approval. This really exemplifies the lowest security vulnerabilities in the tech industry. It enhances our ability to better cope with the many risks that AI is creating.

As I look ahead at the year, our Arista 2.0 momentum continues to march on and resonate. Our demand is actually the best I've ever seen in my Arista tenure. The supply, however, is a slightly different and opposite tail. We are experiencing industry-wide shortages across the board, be it wafers, silicon chips, CPUs, optics and, of course, memory that I referred to last quarter, coupled with elevated costs to procure these.

Clearly, our demand is outstripping our supply this year. While we hope the supply chain will the next year or 2, the Arista operations team has been diligently engaging with our vendors in strengthening supply agreements and engaging in multiyear purchase commitments. We anticipate gross margin pressure due to mix and trade-offs we are making to pay more to assure supply continuity to our customers. Nevertheless, it gives us confidence to increase our forecasted growth slightly to 27.7%, aiming now for $11.5 billion for 2026. We also increased our AI target now to $3.5 billion this year, thereby more than doubling our AI sales annually. And with that good news, over to you, Chantelle for the financial details.

Thank you, Jayshree. I continue to be impressed by our company's ability to deliver such a breadth and depth of networking innovation. It is a core tenet that underpins our strong financial return to shareholders. [indiscernible] want to detail our most recent financial outcomes. To start off, total revenues in Q1 were $2.71 billion, up 35.1% year-over-year and above our guidance of $2.6 billion. Growth was seen across the customer sectors led by our AI and specialty providers customers within the quarter. International revenues for the quarter came in at $418.9 million or 15.5% of total revenue, down from 21.2% last quarter. This quarter-over-quarter decrease was primarily influenced by Americas-based sales to our large global customers. The overall gross margin in Q1 was 62.4% within the guidance range of 62% to 63% and down from 63.4% in the prior quarter. This quarter-over-quarter decrease is due to the lower mix of sales to our enterprise customers in the quarter. Operating expenses for the quarter were $396.8 million or 14.6% of revenue, down slightly from last quarter at $397.1 million.

Our R&D spending came in strong at $271.5 million or 10% of revenue, despite a slight sequential decrease due to the timing of new product introduction costs, Arista continues to demonstrate its commitment and focus on networking innovation. Sales and marketing expense was $103.5 million or 3.8% of revenue, down from 4% last quarter, representative of the highly efficient Arista go-to-market methodology. Our G&A costs came in at $21.8 million or 0.8% of revenue, down from $26.3 million last quarter, reflecting our strong base cost productivity within a pure-play networking business model.

Our operating income for the quarter was $1.29 billion or 47.8% of revenue. Let me pause here to thank the greater Arista team for all of their efforts and resulting excellent execution in a dynamic environment. Other income and expense for the quarter was a favorable $110.8 million, and our effective tax rate was 21.1%. Overall, this resulted in net income for the quarter of $1.11 billion or 40.9% of revenue. Our diluted share count was 1.27 billion shares, resulting in a diluted earnings per share for the quarter of $0.87, up 31.8% from the prior year.

Now turning to the balance sheet. Cash, cash equivalents and marketable securities ended the quarter at approximately $12.35 billion. In the quarter, we did not repurchase our common stock. Of the $1.5 billion repurchase program approved in May 2025, $817.9 million remain available for repurchase in future quarters. The actual timing and amount of future repurchases will be dependent on market and business conditions, stock price and other factors.

Now turning to operating cash performance for the -- for the quarter, we generated approximately $1.69 billion of cash from operations in the period, the strongest in the history of Arista. This was driven by a robust earnings performance, coupled with an increase in deferred revenue. DSOs came in at 64 days, down from 70 days in Q4 due to the linearity of shipments within the quarter. Our inventory turns improved slightly, landing at 1.7% versus 1.5% in the prior quarter. We ended the quarter with $2.38 billion in inventory, up from $2.25 billion last quarter. This marginal increase is a calculated investment in the mix of raw materials to fulfill our growing demand.

Our purchase commitments at the end of the quarter were $8.9 billion, up from $6.8 billion at the end of Q4. As mentioned in prior quarters, this expected activity mostly represents purchases for chips related to new products and AI deployments. We will continue to have some variability in future quarters as a reflection of the combination of demand for our new products, component variability and the lead times from our key suppliers. This could also result in quarters of elevated inventory balances ahead of the deployments. Our total deferred revenue balance was $6.2 billion, up from $5.37 billion in the prior quarter.

The majority of the deferred revenue balance is product related. Our product deferred revenue increased approximately $643 million versus last quarter. We remain in a period of ramping our new products, winning new customers and expanding the use cases, including AI. These trends have resulted in increased customer-specific acceptance clauses and an increase in the volatility of our product deferred revenue balances. As mentioned in prior quarters, the deferred balance can move significantly on a quarterly basis, independent of underlying business drivers. Accounts payable days were 54 days, down from 66 days in Q4, reflecting the timing of inventory receipts and payments. Capital expenditures for the quarter were $54.5 million. We continue the construction work to build expanded facilities in Santa Clara. In Q1, we incurred approximately $40 million in CapEx related to this program and estimate it will reach $180 million in 2026. These Q1 results have provided a strong start to our fiscal year 2026. As Jayshree mentioned, we are now pleased to raise our 2026 fiscal year outlook to 27.7% revenue growth, delivering approximately $11.5 billion. We maintain our 2026 campus revenue goal of $1.25 billion and raise our AI fabric school from $3.25 billion to $3.5 billion.

I would like to take this opportunity to remind the audience that the timing and outcome of customer projects with acceptance terms can create quarterly and sequential dynamics that do not follow prior year trends. For gross margin, we reiterate the range for the fiscal year of 62% to 64%, inclusive of mix of anticipated supply chain cost increases for memory and silicon. Given this challenging supply backdrop, I am proud of our sourcing team's execution, which strongly contributes to the gross margin outlook holding in our guidance range. We feel confident that we can source the necessary supply to meet our customers' needs. Our operating margin outlook remains at approximately 46% for the fiscal year, with the tax rate expected at 21.5%. On the cash front, we will continue to work to optimize our working capital investments with some expected variability in inventory and cash flow from operations due to the timing of component receipts on purchase commitments. More specifically, now our guidance for the second quarter is as follows: now with the added quarterly metric of diluted earnings per share, revenues of approximately $2.8 billion, gross margin between 62% and 63%, operating margin between 46% and 47% and diluted earnings per share of approximately $0.88 with approximately 1.27 billion diluted shares. Our effective tax rate is expected to be approximately 21.5%. In closing, we are optimistic about the fiscal year ahead. The industry has many times demonstrated the pattern of landing on Ethernet is the winning technology, and that is where Arista shines best. We appreciate our customers' choice of working with us to achieve their business outcomes. Now Rudy, back to you for Q&A.

Thank you, Chantelle. [Operator Instructions]

Thank you for your understanding. Regina, please take it away.

[Operator Instructions]

Our first question will come from the line of Simon Leopold with Raymond James.

Great. I wanted to explore your commentary around the scale across opportunity in particular. And I guess what I'm trying to get a better sense of is how much revenue, if any, did that contribute last year? And how material is that to the $3.5 billion forecast you're giving this year? And how should that trend longer term?

Sure, Simon. I think last year, on scale across, we were just beginning. So I think they were small numbers. And majority of the numbers were really scale out. That's sort of our heritage and that's where we excel. If I were to anticipate how it would be this year, again, scale up is virtually 0 and nonexistent because it really only comes to play after the ESN spec. So consider that more a [ 27, 28 ] kind of number. So I think the number will be really shared between scale across and scale out. I don't know if I can say it's 50-50 or 70-30 or 60-40 but scale across will definitely contribute at least 1/3 of our AI number.

Our next question will come from the line of George Notter with Wolfe Research.

Maybe just continuing the discussion on scale up. We are starting to see rack design wins. One of your competitors in the ODM space, I think, has got a couple of designs that they've announced at least. And I know you're kind of pointing towards ESON as being kind of a key catalyst in generating business there. But can you talk a little bit about where you are in terms of designs with customers, progress. Anything you can tell us there would be great. And in fact, I think a few quarters ago, you said you had 5 to 7 scale up rack designs that you were at least working on. I'm just wondering if you can update that.

Yes, that's correct, George. I think there is no doubt in our mind that we will have a number of racks and number of scale-up use cases in 2027. Maybe some of them will be in early trials, but majority of them are looking at really starting with 1.6T and 1.6T chips will really happen in 2027. There may be a few, a handful of them that tried some experimental stuff at 800 gig. But we continue to see at least 5 to 7 rack opportunities. Some of them are multiple racks with the same customer. We're actively designing with them. There's a huge amount of liquid cooling designs with very dense cabling options, acceleration of collectives and memory features we have to work on for low latency. So I definitely feel we're an active engineering phase with Ken and Hughes teams this year.

But unlike the ODMs, I think we're held to a higher bar and we have to just make sure that this thing is production worthy and specification adhering to ESON. So I would say today's scale-up is mostly limited to NVLink from NVIDIA and maybe some PCI switching but majority of the Ethernet scale-up will only really happen in '27 and '28.

Our next question will come from the line of Antoine Chkaiban with New Street Research.

So with the supply outstripping demand, I'm wondering how much does your current supply allow you to grow this year and next. If you update as top line growth guide of 28% growth, a good reflection of how much supply you've secured for this year? And what could that number look like next year based on how much supply you think you can get as of today.

Antoine, I think the supply chain problem, and Todd, maybe you can add to this, is not a 1- or 2-quarter phenomena. We now think it's a 1- or 2-year phenomena. When you -- at first, we thought it was memory. Now it's all the wafer fabrication facilities. Every chip is challenged, and you can see how Chantelle has leaned in with the purchase commitments for multiple years. So while we will continue to improve it, this is a reflection of not just demand, but how much we can ship this year. And as we continue to ship this year, we can give you better visibility on next year. But I can just tell you, we see multiyear demand, and we are going to do everything, including hurt our gross margins to supply to that demand this year and next year because we believe that we certainly don't want to keep GPUs idle and AI infrastructures underutilized because Arista didn't supply the network.

So can the number get better this year? I think this reflects our best attempt at a good number. We started out -- we started at 20% -- 25% growth? Yes. So we started out to 20%, we are 25%, now at 27.7%. Could we improve to the tail end of the year? We'll see. But the amount of de-commits we're seeing doesn't feel good. So we think a lot of this will continue into next year and keep us constrained for the next couple of years.

Our next question will come from the line of Aaron Rakers with Wells Fargo.

Jayshree, last quarter, you had alluded to kind of engagements with other hyperscale cloud titan customers? I think you also pointed to maybe having 1 or 2 new 10% customers this year. I'm curious of where we stand today? Any updated thoughts on adding 1 or 2 new customers at 10% plus? And maybe qualitatively, just talk about your engagements you're having beyond your 2 big cloud titans across the hyperscale vertical.

Yes, absolutely. First of all, 2 big ones. We never take them for granted. Microsoft and Meta, there are all-time favors. They've been on 10% and greater customers for over a decade. And the partnership could never be stronger, and it continues to get better both in cloud and in AI. In terms of the new entrants, we still expect at least one, maybe two and maybe I should caveat this by saying, certainly, in demand, we see 1 or 2. We shall see Todd, how we do on shipments to see if we can achieve the greater than 10%. The 2 of them have very interesting characteristics. They exhibit what I would call the 3 use cases I just alluded to, scale up, scale out and scale across where we really have a fabric notion of creating -- so far, we've been working with them a lot on the front end, and now we get to complement that on the back end, definitely for scale out and scale across and maybe even a little bit of scale up in some of these use cases.

The other thing we're seeing with a lot of these use cases is the lack of power insights and the ability and demand to distribute and get a more multi-tenant scale across is very high in these 2 use cases. A third common thread, we're seeing across of them, much as we all talk about ODM and white boxes, they deeply appreciate the U.S. and the features and the reliability and the observability and the -- just the fact that we have a robust, highly scalable Layer 2, Layer 3 stack commands a lot of superior advantages. So I believe the diversity of these cloud titans is largely due to the fact that we have great hardware and software combined. Ken, you want to say a few words on that?

It's just been an incredible journey to live through this and see the level of infrastructure that all we're getting and how well positioned our hardware and software road maps are to address these ever evolving more [indiscernible] use cases. [indiscernible] to get work on the store.

That's always fun when your job is a blast. So [indiscernible], I still see 1, maybe 2 10% customers. And Todd, hopefully, we can ship it -- sorry, Aaron.

And our next question will come from the line of Ben Reitzes with Melius Research.

There you go, Jayshree, here I am. So yes, I wanted to ask around constraints. Are you able to say what the number was in the quarter and what it's taking away in terms of the $2.8 billion guide? Is it safe to say things would have been $100 million or $200 million higher for both? And then if you don't mind, just if you can touch on why the gross margin should go back up to 63. What is it that you guys are doing that at gives us confidence that it can actually expand a tad from here?

Yes, I think I'll just -- Chantelle, [indiscernible] I think that -- I don't think the commentary about the demand outstripping the supply as of Q1, Q2. I think we're talking about looking ahead Q3, Q4 into next year. So I don't think there's something outside of what we've guided what we've delivered in the first half. I think in the sense of the margin. So the margin is a mix of things, right? And I think that all the team members are executing in full force. I think the supply chain is doing everything they can on ensuring that we have the best supply at the best price. And so we've incorporated that I think that the mix of customers, the only chance for mix expansion or margin expansion would be due to mix. And so I think that's the opportunity as we look to see what we can deliver in the second half then. I think that would be the opportunity.

The teams are also doing everything they can to make sure we control our costs, especially on the manufacturing side, and that includes bringing on secondary providers, calling new components, et cetera. to make our supply chain more resilient and more cost effective in [indiscernible].

And one thing to clarify also on gross margins. So we view this as a partnership with our customers. So while we would consider and have raised prices a little bit, unlike our competitors, we haven't done 2 pricing ceases. We haven't done major price increases. And the price increases really come into play once our backlog starts to reduce, right? So you won't see the impact of that. So our gross margins are a strong factor of cost going up and are still eating a lot of the costs and giving our customers the benefit and promise of the pricing we said we would give to them.

Our next question will come from the line of Michael Ng with Goldman Sachs.

I was just wondering if you could talk about whether or not Arista is seeing networking attach opportunities for customers that are using TPU or TPU like architectures. And then -- anything you could comment about as it relates to growing Neo cloud traction. Is that something that you think may be a little bit underappreciated by the analyst community.

Yes, Michael, you're absolutely right. I'll take your second question first. It's easy to talk about the titans because the numbers are so ginormous, right? But the new clouds are a very important sector because they don't always have the staff to do everything they want to do, and they really lean on Arista's design expertise, U.S. expertise, network design configurations we can provide them a family of 22 products we have in AI. So yes, I would agree with you. It's an underappreciated and the neocloud was very strong this quarter if I recall, Chantelle, for us in the specialty and cloud providers. What was the other question? You had 1a, 1b?

The TPU.

Yes, the TPU. So in general, we are seeing diverse accelerators. Last time I spoke about the AMD accelerators. This time, I will definitely give a nod to the TPUs because in particularly scale across use cases, we're seeing multi-tenants connecting to different AI accelerators, including TPUs as well. So I think the diversity of accelerators is creating tremendous multi-accelerator opportunity and multiprotocol features that we can provide for them in our network.

Our next question will come from the line of Sean O'Loughlin with TD Cowen.

Great. Congrats on the results, and thanks for letting me joining on the fun here. Jayshree, I wanted to get your thoughts on -- we've been talking a lot about agentic AI and the demands that it's placing on maybe some of the more general purpose infrastructure that we has been maybe in the background over the last couple of years. You've talked in the past about a 2:1 pressure on front-end networking created by back end. First, I guess, is that still the correct way to think about it? And second, as a genic workflows become more common, is there any additional demand from your perspective, having a single-image EOS platform on the front and the back end? Or is the front and back end still pretty siloed.

Yes. Well, first of all, Sean, welcome to your first call. It will be fun. Join the fun. So agentic AI, it's kind of a buzzword, but let me sort of break it into how -- the biggest killer application we see in agentic AI right now is still training. And indeed, it's going to move to more distributed inference. And we'd also like to see agentic AI move into a lot of enterprise use cases, all of which we're seeing, by the way, but I would say large, medium, small, the largest killer agentic AI application is training, the medium is enterprise and the smallest -- medium is inference and the small is obviously enterprise. The -- in terms of back end versus front end, we are now seeing way more back-end activity, particularly with our large AI titans and cloud titans because there is just so much scale they need to prepare for the billions of parameters and tokens, and this is where a lot of -- so much so that I think the front end, they might come back and refresh, but they're almost ignoring right now in favor of the back end.

Having said that, though, by virtue of the back-end deployments, I don't know if we any more see a 2:1 to the front end, but we at least see a 1:1. And the 1:1 can be wide area, CPU and storage. Those are probably the 3 common use cases. Not all the customers are up and lifting everything and doing all 3, although we've had cases where some of them did an upgrade at the front end before they went into the back end. But usually, they will have to come back to that because the minute you put that kind of performance pressure and scale on the back end, you almost have to do something in the front end. But at the moment, I would say it's more one-to-one. And at the moment, I'd also say the scale across in the back end has become a bigger use case than we imagined this time last year.

The other thing I had to mention here is just how good it feels to be have the same set of products in the same common operating system management suite and operating model across the front end and back-end. This lowers cost for the customer, simplifies their design process to get that leverage, and we're one of the few vendors who can do that.

I think only.

I think so.

I think only. Yes, absolutely. Good point, Ken.

Our next question will come from the line of Meta Marshall with Morgan Stanley.

Appreciate the question. Maybe just a question on XPO monetization or just how it helps you kind of continue to gain share with customers or just mind share with customers by being so front footed with the technology.

Yes. Thank you, Meta. I think as you know, we're not a classic optics vendor. But almost always, whenever we are selling our switches, you have to connect to something. And usually it's some form of copper or optics. So and these innovations with OSFP, I remember this super well where everybody was saying, "Oh, no, no, we can just use QSFP, has proven to be not only a contribution for Arista, but really for the industry-wide." And that's still how we see it with XTO as well.

While the industry has been talking a lot about copackage optics, these are still science experiments, and they're very proprietary with individual vendors doing their own thing. We embrace open CTO a few years from now, but we think XPO has a 10-year run, especially at 1.6T and [ 3 point T ] where you need liquid cooling and you need that kind of capacity. So all the scale up racks we're talking about wouldn't be possible without XPO or CPC or any one of those technologies. So we see this as just as the last decade was greatly influenced by OSFP. The next decade will be greatly influenced by XPO. And remember, 99% of the optical market today that we connect to is all pluggable optics. So this is a very crucial invention and innovation, not just for Arista, but the industry at large.

I think it's a great example of how Arista enables an ecosystem and then we profit as that ecosystem grows. And with XPO and [indiscernible] is a standard interop [indiscernible] way to get to 4x of [indiscernible] density in liquid cooling, which is absolutely critical for these AI use cases. Without that, you have this huge bottleneck at the front panel, the amount of extra rack stasis required to get through OSFPs. It's -- so we're really enabling the future growth of our industry this way, which we benefit and other benefit as well.

Yes. It's stunning to me. I remember, when I first talked to Andy and Vijay, they said, "Oh, we think we'll get about 20 signatures", and then it was 40, and now it's north of 100. So it tells me the whole consortium is coming together for things like Ethernet, IP and standardization of optics.

Our next question will come from the line of Tal Liani with Bank of America.

I promised [indiscernible] to be nice today. So I have a good question for you.

I promised to be nice too.

Deferred revenues. Deferred revenues doubled in the last year. And it went up -- if I combine short term, long term, it went up $826 million. It went up significantly in the last 4 quarters. What needs to happen? What are the conditions for -- to recognize deferred revenues, meaning what needs to happen for deferred revenues to be recognized over the next few quarters? Is it about data center going live in traffic goes into data centers? Or what are the sources for the deferred revenue increase?

Right, right. So I really do like you. So I'm going to be nice to you not because I have to, because I like to. So I think if you remember 10 years ago, Tal, we had a similar phenomena where in the cloud, the whole Leaf spine design was brand new, nobody really knew how to build it or monetize it and we were building some of the world's largest networks for Azure, et cetera, right? And we had new products, they had new designs. They had done traditionally the access aggregation core and we're now moving to the flat pack topology. And we had some fairly lengthy qualification cycles. So I would say there's a customer aspect of it and a product aspect to it. The customer aspect to it is they need to have the space, they need to have the facilities. They need to have there. In this case, GPUs now back and then it used to be CPUs, they got to have their rack and stack. And in many cases, by the way, we're running into examples where they -- it's literally they need to manually install the cables, and that takes several months, right? Thousands of people have to do that.

So there's certainly a customer acceptance piece of it, which starts with being ready. There's also a new product. Many of these new products in the Arista ethylene family, particularly for the AI are brand new, brand-new chips, brand-new software, the familiarity with it, particularly in the back end was scale out and scale across is new to them. So there's a level of testing and level of making sure it works with the rest of their ecosystem, including the front end that is super important, and Arista bears a huge responsibility to that as well. So all just to tell you that the length of time to qualify this, which used to be 2 to 4 quarters has extended more like 6 to even 8 quarters. So it's gotten much longer. Chantelle, do you want to add something?

Yes. The other thing -- thank you, Jayshree, is that we do recognize some of it every quarter. So it's not like it's on balance, this is aging in [indiscernible]. We recognize things every quarter, things come in and things are recognized to the P&L. So I just want to make sure you understand that the...

It's not piling -- some things go in and some things come up. Yes. Does that make sense, that? Tal, you're on mute?

No, no.

[indiscernible].

We can go to the next question.

Our next question will come from the line of Amit Daryanani with Evercore.

I guess, Jayshree, you folks have kind of positioned XPO as the next OSFP. And I'd love to kind of understand that XPO ramps from the OFC demos to potentially deployments in '27, how do you see change in the optics architecture within AI clusters? And then maybe specifically Arista -- does that change the growth profile or your content per AI IRAC or cluster as we go forward?

Yes. Thank you, Amit. I think you should look at XPO as a partner to OSFP. So at 400 gig and 800 gig you'll be fine with OSFP. And as we go to higher speeds in '27, '28 or even beyond, OSFP will run out of steam, and this will be the new connector of choice. So the migration to higher speeds equals the migration to XPO, particularly for scale out and scale across. Within a rack and scale up, there's still a number of choices. I think within short distances of 2 to 3 meters, you're still going to see a lot of co-packaged copper and I think XPO in terms of density will be another alternative. But I don't rule out open CPO as well over there. They're really looking to maximize dedicity in a minimum amount of space. So I think XPO will be particularly prevalent in scale out and scale across and will be 1 of the choices in scale-up.

Our next question comes from the line of Ryan Koontz with Needham.

This is Jeff Hopson on for Ryan. I appreciate the question. On the scale cross, it seems like that would be a really good fit for all Arista's capabilities. And I know you mentioned it would maybe be around 1/3 of revenue this year. But is this something where scale across could even be larger than scale out over the next couple of years?

Ryan, or rather Jeff, I think the answer to that would lie on how well we do with both. And what form factors are used for both. So majority of the scale across today is a very premier valuables, heavy-duty routing platform, the 7800. So if we do lots of that, it could get well beyond the 30%. But some of them may do it with fixed boxes, too or fixed switches and choose to add a lot of cable in which case, it wouldn't go well above that. So we don't know what we don't know. But I would agree with you that scale across is by far the most significant and differentiated opportunity that really highlights Arista's prowess in both platforms and software.

Our next question comes from the line of Samik Chatterjee with JPMorgan.

Jayshree, maybe slightly related to the last question here. Just trying to think about, you said most of the cloud revenue near-term is going to be scale out and scale across as we wait for scale up to ramp. How are you thinking about your market share when it comes to scale out versus scale across in the early days of scale across, what are you seeing in terms of market share? And are you seeing customer decisions being led in scale across by sort of the incumbent and scale-out or -- is it a different decision altogether in terms of how they're designing vendors for in-force scale across.

Good question, Samik. You're making me think. So I would say If it's greenfield deployment, then they tend to think of it together because they're not only building the sites, but they're thinking of the interconnect across them. And therefore, market share is generally strong in both. In some cases, where Arista has not been a historical participant within the data center, we now have an opportunity to offer the scale across multi-tenant even in a non-greenfield situation and let's say, in a brownfield, where now they've got disparate data centers or AI clusters that we now have to bring in. And so once again, I think Arista's really fitting example to be in scale across both those use cases, but has the additional opportunity in a brand-new data center to be in all use cases, if that makes sense.

So it's giving us a chance to participate with different types of accelerators and different types of models because people aren't getting the power and they're having to distribute the data centers. And as a result of distribution, you need more traffic engineering, routing, multi-tenancy. So I would say scale across is the common denominator in all our use cases and scale up and scale out maybe nice options and brand-new greenfields.

Our next question comes from the line of Karl Ackerman with BNP Paribas.

Jayshree, you are doing more networking design today more than ever. Does that change your ability to monetize your services to capture more of the work of the other value that you're adding to these applications? And I guess as you address that, given the large mix of services revenue within deferred, could services revenue accelerate faster and represent perhaps 25% or 30% of sales going forward?

I don't think so, Karl. I think we're a product company, and majority of our revenue generation and interest in Arista as a company for all the designs we're doing comes from our product heritage. And it's not like we charge for services. In fact, we work closely with our partners also, we will recommend network designs. We will support services and certainly, things like we are the gold standard for worldwide support. But I don't expect services as a function of our revenue to go up. I continue to be -- see ourselves as a product-led company.

Our next question comes from the line of Matt Michman with Truist.

I just want to go back to gross margins. So I know we were sort of in that 62-ish range. They dipped about 170 bps year-on-year. And I wanted to dig into whether it was primarily mix related or maybe if you can quantify whether the -- how significant the memory and cost-related impacts were, if there's any color you can provide.

Yes, I think it's a great question. I would say the majority, if you look at -- even if you look at prior quarter or prior year, the majority of the difference is mix of the customers. And just to clarify, our larger customers have have a lower gross margin accretion. And so that mix is the primary driver. And then the secondary, although not as significant would be things depending on the quarter, depending how deferred moving tariffs or the memory cost or the silicon cost depending on the quarter. So secondary driver, but the primary drivers mix of the customer segments.

Our next question comes from the line of David Vogt with UBS.

This is Andrew for David. From a high level, with $2.4 billion almost of inventory and almost 2 years in COGS of purchase commitments, how should we think about the supply constraints and where that inventory and purchase commitments are not satisfactory to meet demand? Where are the holes in your inventory?

I wouldn't say we have holes in our inventory, but we have surging demand, especially on the newest platforms, which of course, is driving our need for the most modern silicon from our providers and it's driving need for an expanded amount of memory even more than we were expecting before the year began. So that's driving us to be a buyer in the market. Luckily, we've got pretty good spending power. We're a very reliable partner in these scenarios. And so we partner closely with these vendors. But there's no doubt that like the newest platforms that we're delivering, especially in the AI space is driving needs of ours in the high end of our portfolio.

Yes. And just to add to that, David, the real hole is lead times. We are experiencing such significant wafer fab shortages that we're not getting the chips in time.
