Welcome to the Fourth Quarter 2023 Arista Networks Financial Results Earnings Conference Call. During the call, all participants will be in a listen-only mode. After the presentation, we will conduct a question-and-answer session. Instructions will be provided at that time. As a reminder, this conference is being recorded and will be available for replay from the Investor Relations section at the Arista website, following this call. Ms. Liz Stine, Arista's Director of Investor Relations, you may begin.
Thank you, operator. 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; Ita Brennan, Arista's outgoing Chief Financial Officer; and Chantelle Breithaupt, Arista's incoming Chief Financial Officer. This afternoon, Arista Networks issued a press release announcing the results for its fiscal fourth quarter ending December 31st, 2023. If you'd like a copy of this release, you can access it online from our website. During the course of this conference call, Arista Networks' management will make forward-looking statements, including those related to our financial outlook for the first quarter of the 2024 fiscal year, longer-term financial outlooks for 2024 and beyond, our total addressable market and strategy for addressing these market opportunities, including AI, customer demand trends, supply chain constraints, component costs, manufacturing output, inventory management and inflationary pressures on our business, lead times, product innovation, working capital optimization and the benefits of acquisitions, 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. Also, please note that certain financial measures we use on this call are expressed on a non-GAAP basis and have been adjusted to exclude certain charges. We have provided reconciliations of these non-GAAP financial measures to GAAP financial measures in our earnings press release. With that, I will turn the call over to Jayshree.
Thank you, Liz. Thank you, everyone, for joining us this afternoon for our fourth quarter 2023 earnings call. 2023 has been another memorable year for Arista. We gave initial guidance of 25% year-over-year revenue growth and instead achieved well beyond that at 33.8%, driving revenue to $5.86 billion, coupled with a record non-GAAP earnings per share for the year of $6.94, up in excess of 50% annually. Back to some Q4 specifics. We delivered revenues of $1.54 billion for the quarter, with a non-GAAP record earnings per share of $2.08 due to a one-time favorable tax rate. Services and software support renewals contributed approximately 17% of revenue. Our non-GAAP gross margins of 65.4% were influenced by improving supply chain and greater enterprise mix. International contributions for the quarter registered at 22.3%, with the Americas at 77.7%. This was one of our strongest-performing international quarters in recent history. Shifting to annual sector revenue for 2023. Cloud titans contributed significantly at approximately 43%. Enterprises, including financials, were strong at approximately 36%, while the providers were at 21%. Both Meta and Microsoft have greater than 10% customer concentration at 21% and 18%, respectively. Despite multiple CapEx reductions last year and the normal volatility of cloud titan and AI pivot, we cherish our privileged status with both Meta and Microsoft. Speaking of AI, in fall of 2023, Andy and I attended the 50th golden anniversary of Ethernet at the Computer History Museum. It truly is a reminder of how familiar and widely deployed Ethernet has become, with the speed increasing by orders of magnitude from a shared collision 2.95 megabits for file printed share to a terabit Ethernet switching in the AI and ML era. AI workloads are placing greater demand on Ethernet, as they are both data and compute-intensive across thousands of processes today. Basically, AI at scale needs Ethernet at scale. AI workloads cannot tolerate delays in the network because the job can only be completed after all flows are successfully delivered to the GPU clusters. All it takes is one culprit of worst-case link to throttle an entire AI workload. Three improvements are being pioneered by Arista and the founding members of the Ultra Ethernet Consortium to improve job completion time. Number one, packet spraying. AI network topology needs packet spraying to allow every flow to simultaneously access all parts of the destination. Arista is developing multiple forms of load balancing dynamically with our customers. Number two is flexible ordering. Key to an AI job completion is the rapid and reliable bulk transfer with flexible ordering using Ethernet links to optimally balance AI-intensive operations, unlike the rigid ordering of InfiniBand. Arista is working closely with its leading vendors to achieve this. Finally, network congestion. In AI networks, there's a common incast congestion problem whereby multiple uncoordinated senders can send traffic to the receivers simultaneously. Arista's platforms are purpose-built and designed to avoid these hotspots, evenly spreading the load across multi-packs with our virtual output queuing (VoQ) lossless fabric. In terms of annual 2023 product lines, our core, which consists of cloud, AI, and datacenter products, are built upon our highly differentiated Arista Extensible Operating software system stack. It is successfully deployed across 10, 25, 100, 200, and 400-gig speeds. Our cloud networking products deliver power-efficient, high availability zones without doubling the cost of redundancy as datacenters demand insatiable bandwidth capacity and network speeds for both the front-end and back-end storage and compute clusters. The core drove approximately 65% of our revenue. We continue to gain share in our highest performance switching of 100, 200, and 400-gig ports to obtain the number one position at approximately 40-plus percent, according to industry analysts. We have increased our 400-gig customer base from 600 customers in 2022 to approximately 800 customers in 2023. We expect both 400 and 800-gigabit Ethernet will emerge as important pilots for AI back-end GPU clusters. We are cautiously optimistic about achieving our AI revenue goal of at least $750 million in AI networking by 2025. Our second market is network adjacencies comprised of routing, replacing routers, and our cognitive campus workspaces. We continue to make progress in the campus, aiming for the $750 million in revenue by 2025 that we have shared at many Analyst Days. Our investments in cognitive wired and wireless, zero-touch provisioning, and the introduction of AGNI, Arista Guardian for Network Identity as well as AVA sensors for threat mitigation resonate well with our campus customers. The post-pandemic campus is seeking network-as-a-service overlay and zero-trust network embedded in with high availability, observability, and consistency across our OS and management domains. We are also successfully deployed in many routing edge and peering use cases. Just in 2023 alone, we introduced six EOS software releases across 600 new features and 50 platforms. In fall of 2023, we introduced our WAN routing system with a focus on scale, encryption, and WAN transit routing capabilities. It has positioned us well, giving our customers a seamless enterprise LAN and WAN portfolio. The campus and routing adjacencies together contribute approximately 19% of revenue. Our third category is network software and services based on subscription models such as Arista A-Care, CloudVision, DANZ Monitoring Fabric, or DMF observability and advanced threat sensors for network detection and response. Arista's subscription-based network services and software contributed approximately 16% of the total revenue. We surpassed 2,400 cumulative customers with CloudVision, pivotal to building a modern operating model for the enterprise. Please note that perpetual software licenses are not included here and are counted inside the core or adjacent markets. While 2023's headline has been mostly about AI we are pleased with the momentum of enterprise and provider customers as well. Arista continues to diversify its business globally with multiple use cases and verticals. We have more than doubled our enterprise revenue in the last three years and we are becoming the gold standard for client-to-cloud-to-AI networking with one EOS and one CloudVision foundation. Our million-dollar customer logos increased steadily in 2023 at approximately 35% as a direct result of our campus and enterprise momentum. Three principles continue to differentiate us as we are poised to be a market-share gainer in the enterprise. One, best-in-class, highly available proactive products with resilience and hitless upgrades at multiple levels. Two, zero-touch automation for predictive client-to-cloud one-click operations that rely less on human staff or manual operations and are instead software-driven. And finally, prescriptive insights based on AIML autonomous virtual assist AVA algorithms for increased security, observability and root cause analysis. Our foundational and network data lake architecture and the ability to gather, store and process multiple modalities of network data is the only way to reconcile all the incongruent silos for network operators. While legacy vendors that are 30 to 40 years old are aiming for consolidation, Arista remains the only pure-play networking innovator earning top spots in Forrester Wave's programmable switching and customer validation in Gartner's voice of customer for campus in 2023. In December 2023, we conducted one of our largest customer events called Innovate in Vegas. While not my most favorite location, our customers and prospects found it very exciting and compelling for their network transformation initiatives. They resonate deeply with our Arista 2.0 vision, building best-of-breed, data-driven networking platforms. In summary, as we wrap up another fantastic year in 2023, I am so proud of the team's execution across multiple dimensions. They have all worked tirelessly to improve our operational metrics such as lead times, gross margin, and on-time shipments. Simply put, we outpaced the industry in quality, support, and innovation. We set the direction for the future of networking, working intimately with our strategic customers. Despite limited visibility at this time, we reiterate our double-digit growth of 10% to 12% from Analyst Day, aiming for approximately $6.5 billion in 2024. With that, I'd like to turn it one last time to review our financial metrics with Ita Brennan. Ita?
Thanks, Jayshree, and good afternoon. This analysis of our Q4 and full year 2023 results and our guidance for Q1 2024 is based on non-GAAP and excludes our non-cash stock-based compensation impacts, certain acquisition-related charges, and other non-recurring items. A full reconciliation of our selected GAAP to non-GAAP results is provided in our earnings release. Total revenues in Q4 were $1.54 billion, up 20.8% year-over-year and towards the upper end of our guidance of $1.50 to $1.55 billion. Services and subscription software contributed approximately 17% of revenue in the fourth quarter, up from 16.8% in Q3. International revenues for the quarter came in at $343.5 million, or 22.3% of total revenue, up from 21.5% last quarter. This quarter-over-quarter increase largely reflected a healthy contribution from our in-region EMEA customers. Overall gross margin in Q4 was 65.4%, well above our guidance of approximately 63%, and up from 63.1% last quarter. As a recap for the year, we continue to see incremental improvements in gross margin quarter-over-quarter with higher enterprise shipments and better supply chain costs, somewhat offset by the need for additional inventory reserves as customers refined their forecast product mix. Operating expenses for the quarter were $262.7 million or 17.1% of revenue, up from last quarter at $255.6 million. R&D spending came in at $165 million or 10.7% of revenue, consistent with last quarter, reflecting a lower level of new product introduction costs versus what we experienced in the first half of 2023 and what we expect for the first half of 2024. This reflects the timing of prototype and other costs associated with the development of next-generation products. Sales and marketing expenses were $83.4 million or 5.4% of revenue, up from $79 million last quarter, due to increased sales compensation and travel costs. Our G&A costs came in at $14.3 million or 0.9% of revenue, up from $12.1 million last quarter, reflecting some seasonal fourth-quarter spending. Our operating income for the quarter was $744 million or 48.3% of revenue. Other income and expense for the quarter was a favorable $54.5 million, and our effective tax rate was 16.8%. This slower-than-normal quarterly tax rate reflected the release of tax reserves due to the expiration of the statute limitations and some true-up of jurisdictional earnings mix. This resulted in net income for the quarter of $664.3 million or 43.1% of revenue. Our diluted share number was 318.85 million shares, resulting in a diluted earnings per share number for the quarter of $2.08, up 47.5% from the prior year. Now turning to the balance sheet. Cash, cash equivalents, and investments ended the quarter at approximately $5 billion. We did not repurchase shares of our common stock in the quarter. To recap our repurchase program to date, we have repurchased $855.5 million or 8 million shares at an average price of $107 per share under our current $1 billion Board authorization. This leaves $144.5 million 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 fourth quarter. We generated approximately $526.5 million of cash from operations in the period, reflecting strong earnings performance combined with some increase in deferred revenue offset by reductions in taxes payable. DSOs came in at 61 days, up from 51 days in Q3, reflecting the timing of shipments and seasonal strength in service renewal billings. Inventory turns were 0.07 times, down slightly to 1.1 last quarter. Inventory increased slightly to $1.95 billion, reflecting the ongoing receipt and consumption of components from our purchase commitments and an increase in switch-related finished goods. Our purchase commitments at the end of the quarter were $1.59 billion, down from $2 billion at the end of Q3. We expect to continue to reduce our overall purchase commitment number. However, we will maintain a healthy position related to key components, especially as we focus on new products. Our total deferred revenue balance was $1.51 billion, up from $1.195 billion in Q3. The majority of the deferred revenue balance is services-related and directly linked to the timing and term of service contracts, which can vary on a quarter-by-quarter basis. Our product deferred revenue balance increased approximately $153 million over last quarter. This was ahead of our expectations for the quarter and yet again shows that this balance can move significantly on a quarterly basis. As of now, we expect this balance to decline somewhat in Q1 '24, but still be up significantly from Q3 '23 levels. Accounts payable days were 72 days, up from 44 days in Q3 due to the timing of inventory receipts and payments. Capital expenditures for the quarter were $6 million. I would now like to turn the call back to Jayshree. Jayshree?
Thank you, Ita, first of all, for an incredible eight and a half years as our Chief Financial Officer. We're going to miss you a lot and wish you all the best in your next innings. And if you ever miss an earnings call, please come; we'll invite you for one. Now, to describe our Q1 2024 guidance, it's my pleasure to introduce our incoming Chief Financial Officer, Chantelle Breithaupt, for her very first earnings call at Arista. Welcome, Chantelle.
Thank you, Jayshree. Ita, congratulations on all that you've achieved during your tenure with Arista. Your partnership during our transition is greatly appreciated. Since joining Arista, I've been impressed by both the outstanding leadership team and the highly innovative engineering team who both serve a set of marquee customers that are redefining the future of networking. Arista began shipping products in 2008 and in 15 years, the annual bandwidth of the datacenters has grown 350 overall. In just the past two years, the annual bandwidth has doubled with Arista shipping a cumulative 75 million ports in that timeframe. Our acceleration of the data center switching market in recent quarters is evidenced by our market share gains in the 20-plus percent range of both ports and dollars. I am thrilled to be joining Arista at such an exciting time. Now turning to our outlook for the first quarter of 2024 and the remainder of the fiscal year. We remain confident with our Analyst Day view which calls for fiscal year 2024 revenue growth of 10% to 12%. This reflects our outlook for moderated cloud spending after multiple years of accelerated growth combined with a continued growth trajectory in the enterprise business. For gross margin, we reiterate the range for the fiscal year of 62% to 64%, with Q1 '24 expected to be at the lower end due to a heavier cloud mix including some expected release of deferred revenue. In terms of spending, we expect to invest in gross spending faster than revenue. In line with our Analyst Day view, with an operating margin of approximately 42% in 2024. This incremental investment may include go-to-market resourcing and increased new product introduction costs to support our product roadmap. This latter trend is already evident in Q1 ‘24 as R&D is expected to rebound from the unusually low levels in the second half of 2023. On the cash front, we will continue to work to reduce our working capital investments and drive some further reduction in inventory as we move through the year. Our structural tax rate is expected to remain at 21.5%, back to the usual historical rate, up from the unusually low one-time tax rate of 16.8% experienced last quarter, Q4 FY '23. With all of this as a backdrop, our guidance for the first quarter, which is based on our non-GAAP results and excludes any non-cash stock-based compensation impacts and other non-recurring items, is as follows. Revenues of approximately $1.52 billion to $1.56 billion, gross margin of approximately 62%, and operating margin of approximately 42%. Our effective tax rate is expected to be approximately 21.5% with approximately 319.5 million diluted shares. In summary, I am excited to lead Arista's 2.0 journey as CFO. We will migrate our best-of-breed products to best-of-breed data-driven platforms, enabling our impressive TAM of $60 billion. With that, I now turn the call back to Liz for Q&A.
Thank you, Chantelle. 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 a single question. Thank you for your understanding. Operator, take it away.
Operator
Thank you. We will now begin the question-and-answer portion of the Arista earnings call. Your first question comes from the line of Aaron Rakers from Wells Fargo. Please go ahead. Your line is open.
Yeah, thanks for taking the question. And Ita, it's been great working with you. Wish you the best in retirement. I guess my question is, Jayshree, just obviously the focus on AI and the build-out of the backend networks based on 400 and 800 gig ethernet, I'm just curious, like, as we progressed through these last three months, how has your views evolved? And just remind us of the cadence of kind of product cycles that really set the table for risk in this AI opportunity as we move through ‘24 and particularly into ’25? Thank you.
Thank you, Aaron. And yes, we will all miss Ita. So our AI performance continues to track well for the $750 million revenue goal that we set last November at Analyst Day. To give you some color on the last three months, I would say it's difficult to project anything in three months. But if I look at the last year, which may be a better indication, we have participated in a large number of AI bids. When I say large, I should say they're large AI bids, but there are a small number of customers actually, to be more clear. In the last four out of five AI networking clusters, we have participated on Ethernet versus InfiniBand; Arista has won all four of them for Ethernet, though one of them still stays on InfiniBand. So these are very high-profile customers. We are pleased with this progress. But as I said before, last year was the year of trials. This is the year of pilots. True production truly sets in only in 2025.
Operator
Great. Your next question comes from the line of Tal Liani from Bank of America. Please go ahead.
Hi. I'm trying to figure out a correlate because we don't have the backlog contribution of last year; I'm trying to kind of dissect the numbers and see what's the correlation with core data center business and traditional compute. So if server sales cycle is low and we see some declines in servers, does it mean that at least in the short run, excluding the backlog contribution, there is also a decline in the orders? Just how does it work between server demand and switching demand? Thanks.
Yeah. So, Tal, first of all, as you know, Ita and I, or Chantelle and I, would never comment on bookings, orders. We find these all to be kind of useless metrics, because ultimately what matters is what we ship, which is revenue. But just to sort of answer your question on the ratio of CPUs, or for that matter, GPUs in the future to the network, typically we have to have the CPUs or GPUs come in before we can outfit the network. They kind of go hand in hand, but as you know, in AI, we've been waiting for the GPUs, and in the last couple of years, they've been waiting for everything with a long lead time. But I would say generally in the leaf architecture, they go hand in hand where you have to create a rack of 1,000 servers or whether they're CPUs or GPUs. And generally, they look to rack and stack the cable, the CPUs, and the network together. On the spine, which connects all of our leaf, that decision can be made independently even if the processors are not available. So on the leaf, it's more correlated; on the spine, it's not.
Great. Thank you.
Thank you.
Operator
Your next question comes from the line of Sebastian Naji from William Blair. Please go ahead.
Great. Thank you. I just wanted to start and echo everyone's commentary and wish you the best, Ita. It's been a pleasure. My question has to do with white box. People have been talking about the threat for white box since Arista's been around, and it hasn't really impacted Arista's ability to grow. Can you maybe articulate why you believe in the world of AI networks more of the market would not move to white box or vice versa maybe why more of the market would move away from white box?
It's a good question, Sebastian. Thank you. Look, I think white box is here to stay for a very long time if somebody just wants a throwaway commodity product. But how many people want throwaway commodity in the data center? They're so mission-critical. And they're even more mission-critical for AI. If I'm going to spend multi-million dollars on a GPU cluster, then the last thing I'm going to do is put a toy network in, right? So to put this sort of in perspective, we will continue to coexist with the white box. There will be use cases where Arista's blue box or a standalone white box can run either SONiC or FBOSS, but many times the EOS software stack is really something they depend on for availability, analytics, and automation. And you can get your network for zero cost, but the cost of downtime is millions and millions of dollars. So we have always embraced white box; we coexist with it, but it continues to be a relatively small use case in the larger mission-critical data centers for enterprise and cloud companies.
Thanks, Sebastian.
Thank you, Jayshree.
Operator
Your next question comes from the line of Matt Niknam from Deutsche Bank. Please go ahead.
Hey, thanks so much for taking the question. Maybe a higher level strategy question. We've seen two of your key networking peers scale up through sizable M&A over the last several months. So, can you talk a little bit about how you view the value of such scale in order to maybe better serve and target both the cloud and AI titan as well as enterprise verticals? Thanks.
Yeah, no, but Matt, that's a good question. I think on the cloud and AI, we feel pretty bulked up to deal with those customers because they don't look for size and bulk; they look for, as you know, networking innovation capabilities, and this has been Arista's heritage for 10 years and will continue to be with the AI cycle for the next foreseeable 10 years. On the enterprise, there are multiple markets and size helps. I think if you are targeting the early adopters, Arista has traditionally done very, very well there. The last three years is a good example of how well we've done there, both in the data center and in the campus. If you look at the next category of sort of the not necessarily the screaming early adopters, but maybe the fast followers, I think Arista will continue to do well there in the large enterprise. We are so underserved and under-penetrated in both the Fortune 1000 and the Global 2000. We've got a long, long way to go. We probably have 20% of those customers. We've got 80% of them left to go. And I'm not even talking about the mid-market and the SMB, which is a whole other market that we are underserved in. So absolutely, we need to make more investments in enterprise there. When I look at what Anshul, Chris Schmidt, and Ashwin are doing, this is exactly where we're doubling down. This is exactly where we doubled down in the last three years post-pandemic. We have more than doubled our revenue and increased our logo presence because of this investment in enterprise. I can't comment on the consolidation of vendors, but when vendors don't grow, five plus five sometimes is 10. But to be careful on integration, five plus five can sometimes be seven too. So that's somebody else's responsibility, not mine. I think we can get a lot of organic growth.
Operator
Your next question comes from the line of Meta Marshall from Morgan Stanley. Please go ahead.
Great, thanks. Jayshree, maybe just a question. You noted limited visibility and I understand that this is early in the year. But would you say that it's timing of when some of these back-end pilots scale into production? Is it kind of level of front-end spending? Is it enterprise projects? Just like where you're finding just more commentary on the visibility comment? And then second question, you guys noted on the gross margin, but it's a portion of mix and kind of supply chain costs coming down. But just, if there's any one bias toward what led to the gross margin upside in the quarter. Thanks.
Yeah, maybe I'll take that last one first. I mean a lot of the upside in the fourth quarter was really just customer mix, right? I mean we were weighted heavily towards enterprise in Q4, not for any particular reason, it just happened to be that way, and that kind of dropped the margins higher.
And, Meta, to answer your question on enterprise and AI activity, I think Arista continues to drive the concept of EOS, multi-domain routing, campus, high availability, mission-critical enterprises for multiple verticals. We're making good progress there, and this is going to be part of our mainstream innovation and go-to-market. On the AI side, we continue to track well. I think we're moving from what I call trials, which is connecting hundreds of GPUs to pilots, which is connecting thousands of GPUs this year, and then we expect larger production clusters. I think one of the questions that we will be asking ourselves and our customers is how these production clusters evolve. Is it going to be 400, 800, or a combination thereof? The role of the Ultra Ethernet Consortium and standards and the ecosystem all coming together, very similar to how we had these discussions in 400 gig will play a large part. But we're feeling pretty good about the activity, and I think moving from trials to pilots this year will give us considerable confidence on next year's number.
Great. Thanks.
Thank you.

Your next question comes from the line of James Fish from Piper Sandler. Please go ahead.
Hey, thanks for the question. Maybe, Ita, for you, and I'll miss having you on here, by the way, congrats on retirement.
Thank you.
But what's causing the delay in being able to ship that we saw with that product deferred revenue jump as much as we did, or should we think about this as normal to see this level of jump in Q4 based on what you've disclosed in the past? It doesn't seem like this is a normal jump. I guess what's the hang-up? And with supply chain starting to go the other way, could we actually see the price increases you guys have enacted in the past now have to be given back at some point in '24 or '25?
I believe the deferred revenue is simply a timing issue. It's important to note that for revenue to be classified as deferred, the product must have already been shipped. We've discussed this previously, and I'm sure Chantelle will address it again in the future. The delays are related to the timing of shipments and the introduction of new projects and capabilities that we're testing with customers, which is resulting in this deferred revenue. However, this is not a fundamental issue affecting the business. Regarding pricing, the minimal adjustments we're seeing are just part of the regular pricing landscape as we continue to compete for business. There haven't been any significant changes in that area.
Thanks again.
Operator
Your next question comes from the line of Ittai Kidron from Oppenheimer. Please go ahead.
Thanks, and congratulations, Ita; I will miss you. And good luck to you, Chantelle, in your new role. I have a couple of questions. First, the cloud mix has declined slightly over the year. Can you share your underlying assumptions for 2024? More broadly regarding the 2024 guidance, it seems you are projecting a $600 million increase in revenue year-over-year. Considering your targets for 2025, it appears that a substantial portion could come from AI networking. You seem quite confident in your 2025 targets, so I would expect that 2024 should be equally stable. If I assume that $200 million to $300 million will come from AI networking this year, why do you expect the rest of the business to contribute only $300 million to reach your annual targets? Why is there such cautious optimism in the guidance?
Ita, I'll handle the first question, and then I'll turn it over to Ita and Chantelle to address what you refer to as conservatism. First, I want to highlight that our cloud mix is very strong. However, the key takeaway is that while our cloud mix may have come down, our enterprise sector performed exceptionally well. Since 100% represents our total revenue, when one area excels, it can make others appear less impressive. We are seeing positive results across all three sectors and are pleased with the momentum in enterprise. AI is on the way, and while it played a minimal role in our numbers for 2023, we expect its contribution to grow gradually. Which of my outstanding CFOs would like to address the question on conservatism?
I'll start by thanking you for the well wishes. As we enter 2024, we have a balanced perspective, aiming to explore various options to achieve our yearly goals. We'll clarify the different paths and performance metrics we've outlined in our guidance. Jayshree articulated our expectations for AI development from trials to pilots to production across 2023, 2024, and 2025. We'll navigate what this entails for 2024. However, for now, we're taking a quarter-by-quarter approach, especially with my new role, and will observe how the year unfolds.
All right. Good luck.
Thank you.

Your next question comes from the line of Alex Henderson from Needham & Company. Please go ahead.
Ita, I can't believe you're leaving us. I'm going to miss you. Go ahead.
No, she said she will miss you.
Go ahead, Alex. Ask your question.
So, the question I have really is what are you hearing from the field, particularly in the enterprise segment? There's been a lot of noise about indigestion of large amounts of volume that have been shipped to various companies. And clearly, there's some concern that there's some oversupply over the last year into the enterprise market. And I think you've talked to a lot of CEOs. What are they telling you in terms of where their IT spending intentions are for '24? Where are they saying the spending is going relative to the networking gear versus alternative spending priorities? Thanks.
That's a good question, Alex. I certainly talk to a lot of CIOs and CEOs. If I rewind the clock to January last year, I think price was a lot spookier then. We were going through the whole financial crisis, Silicon Valley Bank, and other challenges. If I now fast forward to a year later, our momentum in the enterprise is actually stronger now than it was a year ago. So all this customer feedback indicates that customers are looking for that innovation, modern network model, CI/CD principles, bringing DevOps, NetOps, SecOps, all of this together. Arista continues, in my view, with the large TAM we have in the enterprise of at least $30 billion out of that $60 billion to find the opportunity to deliver that vision of client to cloud, breaking down operational silos. Today, the CIOs recognize us as the pure-play innovator more than any other company.
Great. Thank you.
Thanks, Alex.

Your next question comes from the line of Atif Malik from Citi. Please go ahead.
Thank you for taking my question. Jayshree, thanks for providing those comments on the four wins against InfiniBand. Now your networking competitor announced a collaboration with NVIDIA on Ethernet AI enterprise solutions last week. Can you talk about what this means for your Ethernet back-end business, if anything?
Yeah. I don't understand the announcement as well as probably my competitor does. I think it has more to do with UCS and Cisco validated designs. Specific to our partnership, you can be assured that we'll be working with the leading GPU vendors. As you know, NVIDIA has 90% or 95% of the market. So, Jensen and I are going to partner closely. It is vital to get a complete AI network design going. We will also be working with our partners in AMD and Intel. So we will be the Switzerland of XPUs, whatever the GPU might be, and we look to supply the best network ever.

Your next question comes from the line of Tim Long from Barclays. Please go ahead.
Thank you. Ita, we'll miss you as well, good luck. I wanted to follow up on the AI question, Jayshree. You mentioned some successes. Could you provide more details? Do you expect these deployments to be primarily with a single vendor, or will there be multiple vendors involved? Did you encounter a different competitive situation than usual in these cases? What are your thoughts on the overall potential of this business? I understand that it currently involves many large customers, but how do you see it evolving with other service providers or in the enterprise sector? Thank you.
Yeah. Thanks, Tim. Okay. So let me just step back and say the first real consultative approach from Arista is to provide our expertise on how to build a robust back-end AI network. So the whole discussion of Ethernet versus InfiniBand becomes really important because as you may recall, a year ago, I told you we were outside looking in; everybody had an InfiniBand HPC cluster that was getting bundled into AI. But a lot has changed in a year. The popular product we are seeing right now as the back-end cluster for our AI is the Arista 7800 AI spine, which in a single chassis with north of 500 terabits of capacity can give you a substantial number of ports, 400 or 800. So you can connect up to 1,000 GPUs just doing that. That kind of data parallel scale-out can improve the training time dimensions, large LLMs, and massive integration of training data. Of course, as we shared with you at the Analyst Day, we can expand that to a two-tier AI leaf and spine with a 16-way CMP to support close to 10,000 GPUs non-blocking. This lossless architecture for Ethernet and then the overlay we will have on that with the Ultra Ethernet Consortium in terms of congestion controls, packet spring, and working with a suite of UEC mix is what I think will make Ethernet the default standard for AI networking going forward. Now will it be sole-sourced? I would be remiss if I didn't tell you that our cloud networking isn't sole-sourced. So probably our AI won't be too. But today's models are moving very rapidly, relying on high bandwidth, predictable latency; the focus on application performance requires you to be sole-sourced initially. Over time, I'm sure it'll move to multiple sources, but I think Arista is very well positioned for the first innings of AI networking just like we were for the cloud networking decade. And one other thing I want to say is although a lot of these customers are doing AI pivots, these AI pivots will result in revisiting the front-end cloud network too. So this AI anatomy is being really well understood, and if you take a deep look at the centerpiece of it, which is all the GPUs, they have to connect to something very reliable, and this is really where we come in. So being actively involved is going to pay a lot of dividends, but we're still very much in our first innings of AI.
Great. Thank you.
Thanks, Tim.

Your next question comes from the line of Ben Reitzes from Melius Research. Please go ahead.
Thank you for the question, Ita. It's been a pleasure collaborating with you, and I appreciate your contributions. I would like to discuss your guidance and the cautious approach from a different perspective. Since your Analyst Day on November 9, there have been some changes regarding 2024. Companies like Microsoft, Meta, and Google have all increased their capital expenditure forecasts for that year. However, your guidance for 2024 remains unchanged, reflecting your typical conservative stance. Additionally, AMD has significantly raised their total addressable market for AI, suggesting they recognize a future demand that many of us acknowledge. In light of these updates since November 9, could you elaborate on your conservatism or guidance for both 2024 and 2025, Jayshree?
So, Ben, I'm going to let my two CFOs speak to the conservatism, and then I'll add more color, how about that? Who wants to go first?
Hey, Ben. Nice to meet you. It’s Chantelle. I think that change from November to January/February timeframe, I don't think would change our guidance on the year. That’s similar to the question before. I think that our guide right now resembles where we think we're at in the sense of what will materialize in '24. We'll take it quarter by quarter. The reflections of the changes you're mentioning, the timing of that, we have to wait and see. There's no guarantee that's within our 12-month guidance timeframe, and we'll watch and wait and see, but Jayshree?
Yeah. I think that says it all. I mean, all the drivers that you mentioned are great drivers; the timing of everything is always complex, right? We'll take it quarter at a time and see how things play out.
And look, if our conservatism changes to more optimism in the second half or more likely in 2025, we'll keep you posted.
Operator, we have time for one last question.

Thank you. Your final question comes from the line of Karl Ackerman from BNP Paribas. Please go ahead.
Yes, thank you for squeezing me in. Good evening from Paris. There have been several companies with the optimal supply chain that indicate the market for 800 gig and early deployments of 1.6T ports will begin to inflect later this year for actually front-end networks. And so I guess why would I be wrong to conclude that your hardware sales would be a leading indicator of that? And I guess, as a result, shouldn't cloud titan revenue grow at least in line with your outlook for 2024 of double-digit growth? Thank you.
Thank you, Karl. History is a good indicator of the future. If you look at our 400-gig, everyone asked me why 400 gig wasn’t taking off in 2019 or 2020. It turned out that it took our ecosystem several years, and of course, the pandemic didn't help when it came to optics or NICs for everything to come together. I believe we will have trials for 800 gig this year, but I think real production of 800 gig will happen in 2025. I would like to be proven wrong and maybe it will come sooner, in which case we will let you know. But for now, this is our best case prediction.
Thanks, Karl. This concludes the Arista Networks Fourth Quarter 2023 Earnings Call. We have posted a presentation, which provides additional information on our results, which you can access on the Investors section of our website. Thank you for joining us today, and thank you for your interest in Arista.
