[Operator:]

Welcome to the third quarter 2017 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. I would now turn the call over to Mr. Charles Yager, Director of Investor Relations. Sir, you may begin.

[Charles Yager:]

Thank you, operator. Good afternoon, everyone and thank you for joining us. With me on today's call are Jayshree Ullal, Arista Networks' President and Chief Executive Officer, Ita Brennan, Arista's Chief Financial Officer, and Marc Taxay, Arista's Senior Vice President and General Counsel. This afternoon, Arista Networks issued a press release announcing the results for its fiscal third quarter 2017. If you'd like a copy of the release, you can access it online at the company's 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 2017 fiscal year, industry innovations or market opportunity and the impact of litigation, which are subject to the risks and uncertainties that we discuss in detail in our documents 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 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.

[Jayshree Ullal:]

Thank you, Charles. Thank you, everyone, for joining us this afternoon for our third quarter of 2017 earnings call. I am pleased to report that we had another solid quarter. We achieved record revenue of $437.6 million, growing 50.8% sequentially year-over-year, coupled with strong profits with a non-GAAP earnings per share of $1.62, and record operating margin of 38.6%. Services contribution was approximately 13% of overall sales. From a geographic perspective, our customers in the Americas made up 71% of our total revenue, while the international theaters contributed higher than normal at 29%. This can be attributed to the highest shipments and organic growth this quarter. We delivered non-GAAP gross margins of 64.4%, well balanced across our verticals and product mix. Our top customers were represented by all five verticals in the following order, cloud titans, Tier 1 and 2 service providers, cloud specialty providers, high tech enterprises and financials. Our new customer acquisition continues to be brisk, especially in the international theaters. A key highlight in the high-tech enterprise vertical was the highest number of customer acquisitions in one quarter, signaling the main stream arrival of million dollar customers in the enterprise vertical. In terms of new introductions in Q3, in this September, Arista introduced a very strategic offering, moving from legacy Places-in-the-Network to Places-in-the-Cloud, called PICs. Our Any Cloud software platform is based on our virtual EOS Router and CloudVision Cloud Tracer for visibility metrics. We are truly enabling hybrid cloud networking with leading partnership offerings including Amazon AWS, Microsoft Azure Stack, Google GCP, Oracle Cloud and Equinix Exchange. Arista Any Cloud is indeed a profound approach, as it extends the compliance and visibility of our EOS from the private premise to the public cloud workloads. This September, Arista showcased our state-of-the-art media and entertainment offerings at the international broadcast conference in Amsterdam, including live multi-vendor video workflows, with over 15 technology partners.

[Ita M. Brennan:]

Thanks, Jayshree, and good afternoon. This analysis of our Q3 results and our guidance for Q4 2017 is based on non-GAAP and excludes all non-cash stock-based compensation expenses and legal costs associated with the ongoing lawsuits. A full reconciliation of our selected GAAP to non-GAAP results is provided in our earnings release. Total revenues in Q3 were $437.6 million, up 50.8% year-over-year and well above our guidance of $405 million to $420 million. Service revenues represented approximately 13% of revenue, consistent with last quarter. International revenues came in at $128.3 million, or 29% of total revenue, up from 25% in the prior quarter. While some of this shift in geographical mix represented the timing of U.S. shipments, we also experienced healthy growth in our in-region international businesses in the period. Overall gross margin in Q3 was 64.4%, consistent with last quarter and favorable to the midpoint of our guidance of 61% to 64%. Higher than anticipated revenue levels, combined with the more favorable customer mix, contributed to this outperformance. Operating expenses for the quarter were $112.9 million, down slightly from last quarter. R&D spending came in at $68.6 million, or 15.7% of revenue, down from $70.9 million in the prior period. This reflects reduced prototype and NRE spending, offset by continued head count growth. Sales and marketing expense was $35.5 million, or 8.1% of revenue, up from $34.6 million last quarter, with increased head count and demo related costs. Our operating income for the quarter was $168.8 million, or 38.6% of revenue. Other income and expense for the quarter was a favorable $1.4 million and our effective tax rate was 24.7%, resulting in net income for the quarter of $128.2 million, or 29.3%. Our diluted share number for the quarter was 79.3 million shares, resulting in a diluted earnings per share number of $1.62, up 95% from the prior year. Legal expenses associated with the ongoing lawsuits came in at $7.9 million for the quarter. As a reminder, these legal costs and related expenses are excluded from our non-GAAP results discussed above. Now turning to our balance sheet. Cash, cash equivalents, and investments ended the quarter at approximately $1.3 billion. We generated $205.9 million of cash from operations in the September quarter. This reflects strong net income performance combined with a decrease in supply chain related working capital. DSOs came in at 45 days, down from 61 days in Q2, reflecting the timing of billings in the quarter. Inventory turns were 1.7 times, up from 1.6 times in Q2. Inventory decreased to $333.2 million in the quarter, down from $363.8 million in the prior period. This reflects reductions at both the raw materials and finished goods level as we continue to optimize our supply chain. In addition, consistent with last quarter, we maintained a further $32 million as inventory deposits recorded in other assets at the end of the quarter. Our deferred revenue balance was $565.1 million, up from $554.5 million in Q2. This balance continues to be made up of short and long-term service contracts and product-related deferrals associated with acceptance terms and future deliverables. Our product deferred revenue declined slightly in the quarter, contributing to our revenue outperformance. Accounts payable days were 19 days, down from 51 days in Q2, reflecting the timing of inventory receipts and payments. Capital expenditures for the quarter were $2.6 million. Now, turning to our outlook for the fourth quarter. We expect revenues to range from $450 million to $464 million, representing 40%-plus year-over-year growth at the upper end of our range. We continue to work closely with customers on the qualification of our 945-related product redesign, and we expect this to have some impact on our business in the quarter. Based on our current outlook, depending on the timing of shipments and product acceptance, we expect our product deferred revenue balance to decline in the period. Operationally, we now have access to international sourcing for our redesigned products following the recent Federal Circuit ruling. As part of our overall supply chain strategy, we will continue to leverage our U.S. manufacturing and some U.S. sourcing capabilities as we move forward. We experienced significant operating leverage in Q3 with operating margins up 38.6%, well above our historical run rates. These margin levels reflect exceptional top line growth in the last number of quarters with revenue growth outpacing spending. While we will remain cautious in relation to our spending ramp, we expect that over time our operating expense investments will gravitate towards long-term model of 20% R&D, 10% sales and marketing, and 3% G&A. In particular, with reference to the fourth quarter, we expect some significant R&D-related investments that will result in higher spending in this area. With this as a backdrop, our guidance for the fourth quarter, which is based on non-GAAP results and excludes any non-cash stock-based compensation expenses and any legal costs associated with our ongoing lawsuit is as follows

[Charles Yager:]

Thank you, Ita. We are now going to move to the Q&A portion of the Arista earnings call. Due to time constraints, I'd like to request that everyone please limit themselves to a single question.

[Unknown Speaker:]

Operator. We will now begin the Q&A portion of the Arista earnings call. Your first question comes from the line of Stanley Kovler of Citi Research. Please go ahead. Your line is open.

[Stanley Kovler:]

Hi, good afternoon, everyone. Thanks very much for taking the question. I just wanted to ask you specifically about cloud, as you anticipated, and the question is really some of your competitors were talking about challenges more in the routing area, and so, there's some architectural shifts that are happening in this space. I know your customers, you said, are going through a period of digestion for your products. What's the opportunity for the regional routing piece of the business into those accounts? Is there an opportunity for additional growth or for growth to accelerate, particularly when it comes to FlexRoute licenses and things like that? Thank you.

[Jayshree Ullal:]

I'll take the question, Stanley. Thank you. So absolutely. I think Arista has been experiencing a changing architecture and a 100-gig transition since we announced these products in 2016. So this is not new for us. And really, we pioneered this change with the FlexRoute license where increasingly what we're seeing as a trend across our customer base is more and more of them want to replace routers with routing. And frankly, legacy vendors are on the wrong side of this trend. So as they may be experiencing a contraction in their routers, we are experiencing an inflection in routing, and our FlexRoute licenses continue to increase. You may remember I had challenged the team to do over 100 customers with FlexRoute in the very first year, and we achieved that last summer, and now, we've exceeded 150 customers.

[Stanley Kovler:]

Thanks. And if I could just follow-up, more on the deferred revenue side, can you help us understand of the flexibility you have in revenue recognition and walk us through, once again, the varying pieces of deferred revenue, and how we should think about that, beyond the two quarters?

[Ita M. Brennan:]

Yeah, I mean, again, I think the makeup of deferred revenue is really two buckets, right? One is services, which is kind of short-term and long-term services, and that gets recognized as those services are delivered over time. And then, we have the product deferred revenue, which is really around acceptance clauses with customers and the delivery of new features, right? And I think the timing of that depends on when you ship and it depends on when the customers accept. In Q3, we saw a slight reduction in deferred. We would have still exceeded the top end of our range without that. So I think it was pretty minimal. As we look into Q4 right now, we'll see where we come out. We expect that it will come down, based on what we can see now, and then, we'll see how it plays out as we go through the quarter.

[Stanley Kovler:]

Thank you very much.

[Operator:]

Your next question comes from the line of James Faucette of Morgan Stanley. Please go ahead. Your line is open.

[James E. Faucette:]

Thank you very much. I wanted to ask you, Ita, on the profitability. I know that you've had a tremendous couple of last quarters, especially relative to your expectations for revenue, and you've also outlined kind of that you plan to get back to your operating model, but what about the gross margin line? That also continued to do quite well, and as a result, you're pulling through again, it looks like, for the December quarter, total operating margins that look to be well above your long-term target. Does it make sense for us to start thinking about your long-term target being closer to the high 20s or 30%? Or how should we think about that? Thank you.

[Ita M. Brennan:]

Yeah, I mean I think what we're seeing, certainly, when the gross margins are operating in the 63% to 65%, is that, much as we thought kind of putting this out there as a target, it's becoming a 30% to 32% operating margin business, and I think we're comfortable with that, certainly, for the near term. Again, the investment thesis, I think, we're clear on. It will take us time to get there, just given the rate that we've grown at. But it's the gross margin, we'll see what it does. But I think those are the drivers, right?

[James E. Faucette:]

Thanks.

[Operator:]

Your next question comes from the line of Vijay Bhagavath of Deutsche Bank. Please go ahead. Your line is open.

[Vijay Bhagavath:]

Yeah, thanks. Yeah, hi, Jayshree, Ita.

[Jayshree Ullal:]

Hi, Vijay.

[Ita M. Brennan:]

Hi, Vijay.

[Vijay Bhagavath:]

Yeah, hi. My question, Jayshree, is on 100-gig port prices are declining, but Arista is beating numbers, in fact, crushing numbers. So like to get your bigger picture view, Jayshree, on what's driving the growth in 100-gig ports? Is it workload growth? Is it buildouts of new data center capacity? Is it legacy port refresh to 100-gig? And how do you prioritize these demand drivers in terms of port growth? Thanks.

[Jayshree Ullal:]

Vijay, that's a good question. I think the 100-gig transition has surpassed even our expectations this year, and as you might know, most market studies show us now as at number one share, with about 40% market share. I think the main reason we're seeing that is because the 100-gig has become the Universal Spine's not only in the data center, but it's sort of stretching, I should say, to incorporate a lot of the switching and routing for regional and data center interconnect. So what we're seeing is this trend, the architectural trend that we've been espousing for a couple of years now, where the LAN, the WAN, and the Layer 2 and the Layer 3 are all coming together to be a highly elastic Universal Spine. And this year has been definitely an inflection year, and a starting year. But I must underline that I see many years of robust growth of 100-gig ahead, and we're just beginning this year. And with the entry of 400-gig, I don't see that the 100-gig in any way will change. So I think what you're seeing is a significant investment with our top customer base across all five verticals. And while we may be a little more aggressively penetrated in the cloud titans, it's really applying to all the verticals.

[Vijay Bhagavath:]

Okay. Thanks, Jayshree.

[Jayshree Ullal:]

Thanks, Vijay.

[Operator:]

Your next question comes from the line of Paul Silverstein of Cowen and Company. Please go ahead. Your line is open.

[Paul J. Silverstein:]

Thanks, guys. I appreciate it. Jayshree, if I could take you back to the Web 2.0 architectural shift question, the specific question being, are any of the cloud titans, those top four, five using FlexRoute at present, or have any of them made awards to you to use FlexRoute going forward for the peering DCI use case. And a related question, I've seen the numbers. They speak for themselves, but are you seeing any inventory buildup and how much visibility do you all have as to the quarterly rhythm of demand from, especially, that cloud titan group? Appreciate it.

[Jayshree Ullal:]

Sure. Because I have a short-term memory, I'll take the first question, and then, I'll go to your second. So visibility with our cloud titans, we continue to have an extremely intimate relationship with them. We have not seen an appreciable change in the visibility or the competitive landscape. As we have repeatedly said, because they are in a high-velocity, high-growth mode, the visibility we get is typically good for one to two quarters. And even then, it can change. It was bigger than we saw in the first three quarters of this year. But it's a very strong communication. There's very strong intimacy. This is an area where not only Anshul Sadana, our Chief Customer Officer participates, but our entire engineering team is very involved in the roadmap, in the demand, along with our systems engineers and sales teams. So I would say we've got good visibility for one or two quarters, and we've got medium to low visibility thereafter. And probably that's just generally true. It's the nature of the business. In terms of FlexRoute license and routing in general, absolutely, some of our early adopters have been the cloud titans right from the beginning in 2016 and they continue to be major deployers.

[Paul J. Silverstein:]

Jayshree, those folks who are adopting FlexRoute, they were previously using an MX router or an ASR 9000? Any sense...

[Jayshree Ullal:]

Yes. Yes.

[Paul J. Silverstein:]

...you can give us for what you just placed then (22

[Jayshree Ullal:]

That's correct. Just to put this in context, until 2016 or 2017, we were only in the leaf and spine layer. With the arrival of the FlexRoute license and the ability to scale and improve and just basically provide more routing features, we entered additional layers of the spine for routing and data center interconnect where traditionally they were core routers either from Juniper or Cisco.

[Paul J. Silverstein:]

I appreciate it. I'll pass it on. Thanks, guys.

[Jayshree Ullal:]

Thanks, Paul.

[Ita M. Brennan:]

Thanks, Paul.

[Operator:]

Your next question comes from the line of Ittai Kidron of Oppenheimer. Your line is open. Please go ahead.

[Ittai Kidron:]

Thanks, and congrats, ladies, and Charles, for the results.

[Jayshree Ullal:]

Thank you, Ittai.

[Ittai Kidron:]

I guess I have – I have I guess – it's multiple questions, but it all ties into one thing which is your R&D investments. You've talked about some delays in certifying the new hardware for the cloud guys, and it's understandable since it wasn't just a simple software workaround. It was a little bit more complex than that. But that delay, plus the fact that R&D expenses are now sequentially down for two quarters in a row, I guess it comes together into this question of, are you under-investing? Are you at a point in time where if you don't ramp very quickly, it will hurt you soon, somewhere, sooner rather than later? And again, tying it to Ita, to your guidance, your guidance implies a massive expansion of OpEx on a quarter-over-quarter basis, and even last year, in the fourth quarter, that has not happened. So unless you have a unique ability to absorb hundreds of employees in an extremely short timeframe, which I doubt you can, because you are very picky about who you pick, help me tie this together. How can you get to those expense levels? On the flip side, Jayshree, how can you keep investing and keep up with everything that's coming up, and the legal certainly throws another wrinkle into this, and some resources have to be dedicated to that? When does this start hurting your business, the fact that you don't have the head count available?

[Jayshree Ullal:]

Okay. Well, we'll try to keep our answer shorter than your question, Ittai, how about that?

[Ittai Kidron:]

That's...

[Jayshree Ullal:]

I'm teasing you. Well, let's see, so I think our engineers know that they have unlimited hiring capabilities, but they have a very high bar. So we continue to hire very, very well in engineering head count, but frankly, many of them don't make our bar. So if we are limiting hiring, it's not because we don't want to hire, but because we are limited by the talent pool in a geography. So one of the things we are doing is expanding geographies beyond our headquarters here in Santa Clara. But I just want to high-five and give kudos to our engineering team for dexterously developing new products, doing very good engineering recruiting and still keeping the bar high. I'm very proud of that. Having said that, what seems to decline and go up and down are the other variable spends. We don't control sometimes the chips and when they come out and the associated prototype and the NRE spending to go with that. So I think, in general, we're doing better in head count on the engineering investment side, but we could do even better and we expect to in spending more money in Q4 in the non-head count department. In terms of the legal, there's no question in our mind that we dedicate a lot of engineering resources to legal. However, over the last three years, which is we're on our third year of legal, we've been doing workarounds for many, many years. And I would say more time was spent this quarter, not necessarily on just developing the legal workarounds, clearly, we had to scramble to do more of that and get it out in September, but also in qualifying it. That's where our systems engineers and our sales and marketing resources were more tested. So overall, I'm comfortable and confident, Ittai, that we can continue the head count ramp and that we can grow into new markets organically, and there's always a possibility we do things inorganically, as well. Ita, you want to add to that?

[Ita M. Brennan:]

Yeah, I mean, Ittai, I think the thing to remember is that the R&D head count and that part of it has been growing consistently, right? Where you see the lumpiness is really all around prototype and NRE type expenses, right? So I think in Q4, as we sit here today, we believe we'll spend some meaningful money on some of those kind of one-time items in the fourth quarter and we'll continue to ramp head count, right? I think over time, our goal is to get back to that 20% of revenue.

[Ittai Kidron:]

Very good. Just a follow-up, Jayshree. As you look into your future roadmap for 2018, has it been delayed because of the legal workaround work or pushed out?

[Jayshree Ullal:]

In some cases, yeah, in some cases, we have had to push out some of our priorities for customers to prioritize legal workarounds that were more time based, yes.

[Ittai Kidron:]

Got it. Very good. All right, good luck.

[Jayshree Ullal:]

Thank you.

[Operator:]

Your next question comes from the line of Alex Kurtz of KeyBanc Capital Markets. Please go ahead. Your line is open.

[Alex Kurtz:]

KeyBanc. Did you like that, Jayshree? So I'll keep it short here. When we think about these three trials that got delayed on the 945, were these projects that were identified and were going to be revenue this quarter, and now, they'll just kind of move into Q4, once the 945's work has been certified? Is that – so there's a real line of sight on this business?

[Jayshree Ullal:]

Well, as I said, we have pretty good line of sight with our cloud titans, and absolutely, there were projects that were identified. Let me reiterate and be really clear that we did not lose to any competitor. It just is taking a long time. It can take anywhere from 2 weeks to as much as 10 weeks to do these certifications. So lengthening the qual cycle and getting them these workarounds in mid-September didn't give us much of a chance to certify them in Q3. So we expect most of them will move to Q4, or worst case, Q1.

[Alex Kurtz:]

And have you seen any shift in top-of-rack versus aggregation mix within the cloud titans, say, over the last couple of quarters and what they're communicating to you about their plans going into 2018?

[Jayshree Ullal:]

From everything I can see, the mix has stayed the same. Obviously, our aggregation has moved more to 100-gig and our top-of-rack has moved to 10-gig, 25-gig, and 50-gig in the leaf, so – but no, we haven't seen any big change in mix.

[Alex Kurtz:]

Okay. And I don't know, is Marc in the room? I just had a question about...

[Charles Yager:]

We need to limit the questions.

[Jayshree Ullal:]

Can we go to the next question, Alex, and we'll get to you later?

[Alex Kurtz:]

Yeah, we'll ask in this call back. No worries.

[Jayshree Ullal:]

Okay, great. Thanks, Alex.

[Operator:]

Your next question comes from the line of Simon Leopold of Raymond James. Please go ahead. Your line is open.

[Simon M. Leopold:]

Thank you very much for taking my question. I wanted to see if we could follow up on this hot topic of what's going on in the cloud. So I understand your explanation and was hoping we could get a little bit of quantification around why the degree that the cloud titans were softer than you expected. And you've cited the evaluation, which while it makes sense to me, I guess I'm trying to understand the bigger industry picture and hoping maybe you can help us understand what's going on with other companies. So certainly, your direct competitors, where you're taking routing business, that makes sense why they would see softer business, but what about all the other companies in the supply chain into web-scale citing slower demand? Can you help me put that in perspective? Thank you.

[Jayshree Ullal:]

Well, it's difficult enough to talk about my company, let alone help you with other companies. I'll try, Simon. I think if I step back and look at the big picture, the reason Arista is less affected by what other companies are is, frankly speaking, we're on the right side of these trends. We're developing 100-gig, we're developing routing, we're developing the right optics and DWDM capability, and these are all the modern architectures that cloud wants to move to. So I guess we don't have the overhead of legacy, is the best way I can say this. We're also underserved and (30

[Simon M. Leopold:]

And can you help us with the quantification aspect, whether percent of revenue or how different it was from what you expected, just any quantification element?

[Jayshree Ullal:]

I said it was slightly lower from prior quarters. Hopefully, that quantifies it.

[Simon M. Leopold:]

I was looking for a number.

[Jayshree Ullal:]

Yeah.

[Ita M. Brennan:]

Simon, I don't know that you can put a number on that. I mean I think at the end of the day, what we're saying is that we're working through the qualifications. We've seen some effects from that, but the business with these customers and the activity levels of these customers, we haven't seen any change in that.

[Simon M. Leopold:]

Thank you very much.

[Jayshree Ullal:]

Thank you.

Please try and limit your questions to just one, folks. Thank you.

[Operator:]

Your next question comes from the line of Erik Suppiger of JMP Securities. Please go ahead. Your line is open.

[Erik L. Suppiger:]

Yes, thanks for taking the question. On the routing products, can you talk about what kind of discounting you've been offering, and how the gross margins on that compared to your traditional switching products?

[Jayshree Ullal:]

Yeah.

[Ita M. Brennan:]

You want to take it, Jayshree?

[Jayshree Ullal:]

No, sure. Go ahead, Ita.

[Ita M. Brennan:]

I think we've always said, Erik, that the routing is accretive, right? And we're definitely – we're creating significant value there versus what's available prior to this shift, and I think we see that that is accretive to the gross margins.

[Erik L. Suppiger:]

Do you – we've heard that you're not discounting nearly as much as on the switching products. Can you talk about what kind of discipline you've had, from a discounting perspective?

[Jayshree Ullal:]

I think our discipline applies to both routing and switching. In general, the customers see the value of our quality of software, the programmability, the underlying architecture being network-wide database oriented, the analytics, the automation, the single binary image. So both of that applies to both switching and routing. Routing, in general, tends to be fewer boxes and fewer ports, but higher margins. And switching is connecting to the servers and storage, so it tends to have more pricing pressure.

[Erik L. Suppiger:]

Very good. Thank you.

Thanks.

Thank you.

Your next question comes from the line of Alex Henderson of Needham. Please go ahead. Your line is open.

[Alex Henderson:]

Thanks. I was just hoping you could clarify your comments. So on the one hand, you're saying that the qualifications for the cloud guys has taken a little longer and is pushing business out of 3Q and then into Q4, and then, on the other hand, you're saying that that's not an impact on the numbers, and I'm not sure I understand what you mean by those two statements. They seem to be contradictory.

[Jayshree Ullal:]

We're saying that we didn't do as well in the cloud titan in Q3 as we did in Q2. That's what we're really saying. But that doesn't mean the other types of customers didn't contribute to our number. So all five verticals did well, and it was very balanced. Cloud titan is still our number one vertical. So I don't think they're mutually contradictory statements. They're actually connected, right?

[Alex Henderson:]

So if the cloud titans are...

[Jayshree Ullal:]

(34

[Alex Henderson:]

If the cloud titans are coming back in on the fourth quarter, and the other guys don't change trajectory, why wouldn't it accelerate in the fourth quarter then?

[Ita M. Brennan:]

I mean we're growing at, like, 50%, year-over-year, Alex, on a quarter-over-quarter basis. I don't know that it accelerates off of that. I think Q3 we had some impacts and Jayshree has said it was a slight impact from the qualifications and so on. And we'll see what happens in Q4, right? We have work to do there, and we're working through that with them.

[Alex Henderson:]

Okay. Great. Thanks.

Your next question comes from the line of Mark Moskowitz of Barclays. Please go ahead. Your line is open.

[Mark Moskowitz:]

Yes, thank you, good afternoon. I have a seven-part question. I'm just kidding.

[Jayshree Ullal:]

Mark.

[Mark Moskowitz:]

One question for me, kind of building off the last question, actually. So given your commentary around certification, we're just kind of curious, in terms of, can you talk a little more about the other customers who are doing well, shouldering some of, maybe, the certification overhang from the cloud titans, because I'm trying to get a sense, as you move into 2018 and beyond, are you going to start standing firmer and taller on other verticals beyond just the cloud, if everything kind of works in unison? Is that routing? Is it enterprise? Like, what verticals are helping offset some of this cloud certification overhang? Thank you.

[Jayshree Ullal:]

I think if I look into 2018, some of the fastest-growing verticals besides obviously a clear contribution from cloud titans that we expect is service providers, high-tech enterprise and cloud specialty providers. All of these three are smaller today for us than cloud titans, but have an ample opportunity for growth. In the case of the service providers, they are going through a re-architecture. They're operationally very dependent on their legacy architecture. So it takes time to move, but we feel optimistic that there are some changes happening there and have already happened there by virtue of service providers now being our second largest vertical for two quarters in a row. The cloud specialty providers, they look a lot like the titans, except their sizes are different. And probably my most exciting message to you would be we feel like the enterprises have a lot of legacy fatigue. And they are starting to show some real momentum, and I expect that this strength we showed here with both international and with enterprise customers, this was our largest number of million-dollar enterprise customer quarter. I hope it's not a one quarter trend and it continues, and that will have some contribution in 2018. Mark? Is that okay? Did I answer all seven parts of your question?

[Mark Moskowitz:]

Yes, thank you. Just one question. Thank you. Good afternoon.

[Jayshree Ullal:]

All righty. Thank you.

Your next question comes from the line of Tejas Venkatesh from UBS. Your line is open. Please go ahead.

[Tejas Venkatesh:]

Thank you. I'm on for Steve Milunovich. I wanted to better understand the lengthened qual cycles you're seeing in the cloud. Is that because your workaround includes using a different silicon vendor?

[Jayshree Ullal:]

Not particularly. So just let me kind of step back and give you some description of the quarter, because it really was an interesting quarter. In the beginning of the quarter, in early July, we were shipping normally, and then, on July 5, we got the cease and desist order, right, Marc, around then?

[Marc Taxay:]

Yes, July 4.

[Jayshree Ullal:]

Okay. So we had a busy season, because as soon as we got the cease and desist order, you might remember that these are the same two patents that were invalidated by the PTAB, that now the International Trade Commission, ITC, issued an order on. So our engineering team had to scramble to get out a workaround on, basically, invalidated patents. We got that dichotomy going on. So we introduced a new EOS release, 4.19, around mid-September. And so now we're actively engaged. We only had two or three weeks in the quarter to certify, and we did do a lot of certifications. But these qualifications times can be related to software only, or in some cases, in the case of the ACL workaround, it can be a combination of software and hardware. And both are features that are not transparent to the customer. In other words, the customer has to put it in and it really depends on their use cases and scale and complexity. So if it's a simple network, they may not need to do much and two weeks may be fine. If it's more complex and they have a lot of ingress and egress ACLs, then you have to go through more qualification. So that's why you have that wide range, because we're committed to non-infringing workarounds on invalidated patents, I might add. However, that engagement with the customer can be short or long.

[Tejas Venkatesh:]

Thank you. And one final question. Could you comment on your software-only revenue and how meaningful it's becoming? You mentioned over 150 FlexRoute software licenses and you also have CloudVision.

[Jayshree Ullal:]

Yeah, no, we not only increased – thank you for letting me speak about that. This is a proud moment, because I think it's an indication of how the networking business is truly migrating to software-driven networking. We not only exceeded 150 routing customers, but we have now also crossed 200 CloudVision customers. And we have several trials going on. So my anticipation is while it is not yet reportable, so, it's not material revenue, and again, because it's a software subscription over multiple years, I expect in the next two years that this business can become approximately a 5% of our revenue.

[Tejas Venkatesh:]

Thank you.

[Jayshree Ullal:]

I guess you'll hold me to that, so check-in in two years.

Your next question comes from the line of George Notter of Jefferies. Please go ahead. Your line is open.

[George C. Notter:]

Hi, guys. Thanks very much. I guess I wanted to ask about some of the latest developments on the routing side. Obviously, there's new silicon in the marketplace. I know you guys are continually kind of working on feature development. The question is, as you continue to drive things on the silicon side and feature side, talk about those features and capabilities and how they expand your TAM on routing. Thanks.

[Jayshree Ullal:]

Okay. Well, I think there are three aspects to how we've gone about our routing endeavor, from a development point of view. One, as you rightly point out, is just using, pardon my French, some kick-ass merchant silicon, right? And what I mean by that is, everybody gets access to the same silicon, but somehow, we've been able to get more routes, more data paths, more convergence, more scale, more services out of it. And this is a true engineering feat that we apply not just the silicon, but this is indeed one of our closest partnerships with Broadcom, especially on the Jericho family and chip set. And it's something we've been doing across three generations, Petra, Arad and Jericho to really maximize the feed, speed, scale, and performance. And I cannot underscore that enough. The second thing is, we augment it and we complement that with our own co-processors, silicon drivers, et cetera, and a set of capability that the silicon may not have to enhance it. And again, this is very important, because in routing, there's routing features, and then, there's use cases that we go into. And so, we've been going into some very specific use cases in the content, media, cloud, routing aggregation, high-performance core, even some 5G wireless. So those become the way we really approach it so that we're not just building, again, yet another router 20 years later, but we're really zooming in on the importance of the features we have, including the third area, which is our EOS programmability and routing protocols. We've got just about every four-letter acronym covered there, including a BGP stack that is much more robust today, as we've been working on it for several years, control planes with VXLAN-EVPN and segment routing, and also MPLS features with some traffic engineering. So it's really been a three-pronged approach to attack and provide simplicity and elegance in our architecture, and yet, state-of-the-art performance and protocols as well.

[George C. Notter:]

And then the TAM question, I guess, I'm just curious about how much you think you're driving the TAM up.

[Jayshree Ullal:]

I think we're contracting the router TAM and increasing the routing TAM, but it's always been difficult to call it out as a separate TAM, because it sits on top of our switches. So I think the platform is the same, but the software TAM is jumping on it. So it's a shared platform with multiple features on it.

[George C. Notter:]

Fair enough. Thanks.

[Ita M. Brennan:]

Thanks, George.

[Jayshree Ullal:]

Thank you, George.

Your last question comes from the line of Hendi Susanto of Gabelli & Company. Please go ahead. Your line is open.

[Hendi Susanto:]

Good evening, Jayshree and Ita. You call out strong International sales in Q3. Where do you see strong International sales in terms of regions, verticals and use cases? Are there certain use cases that drove strong International sales in Q3?

[Jayshree Ullal:]

Yeah, no, this is one of our prouder moments, I think, because we had a lot of international shipments in Q3 and we had a particularly strong Asia-Pac and EMEA. Mark Foss, you've been driving some of this. You want to comment on it?

[Mark Foss:]

Yeah, sure. As mentioned, the Americas business was about 71% of revenue. It broke out to where EMEA was 18%, and the APJ was about 11%. And as Jayshree mentioned, we had a very strong quarter for new customers acquired internationally with over half of the customers – new customers we acquired were international. But the organic international customer revenue has been growing faster than the company average. This removes out any global customers which may be headquartered in the United States. But the organic international customer revenue has actually been very strong for us.

[Jayshree Ullal:]

Yeah, and I wanted to also put in a plug for the leadership team there. Naresh (45

[Hendi Susanto:]

So, use cases are broad-based?

[Jayshree Ullal:]

Yes. Use cases and country adoption is broad-based.

[Hendi Susanto:]

Okay. Thank you.

[Ita M. Brennan:]

Thanks.

[Jayshree Ullal:]

Thank you.
