We look forward to seeing many of you there. .

Now I would like to turn the call over to Lee for his opening remarks.

Lee?.

Thank you, Maria. I'm delighted to be here with you today, and I would like to thank you, all, for joining our first public financial results conference call. We are very pleased with our results, and we believe 2014 is off to a great start. .

In January, we officially launched our TPS product, which is our first standalone security solution for large-scale DDoS protection. Also in January, we introduced our new aCloud Services Architecture to support next-generation Infrastructure-as-a-Service cloud data center architecture. In March, we completed our $193 million initial public offering.

In April, we launched the industry's first 100 Gigabit Ethernet ADC for layer 4 to layer 7 services. .

Also in April, we expanded our Thunder Series of appliances, filling our product portfolio with 4 new midrange and high-end models. And lastly, we established a new three-tiered channel partner program in North America designed to provide our channel with resources and programs to help foster A10 product sales..

Specifically, in the first quarter, the A10 team delivered tremendous growth, and we achieved our third consecutive quarter of record revenue. Revenue grew to $45.7 million, up 55% year-over-year and 8% sequentially. And we delivered this growth with very strong gross margin of 78.2%. .

Highlighting our differentiated application networking platform and the value we provide to a broad range of customers, we've added 200 new customers in the first quarter. Let me share with you a few new customer wins..

First, a large cloud-marketing company chose our ADC solution to expand their network capacity and provide consistent feature and performance across both their physical and virtual networks.

This customers deploying our ADC solution on a Thunder box in their large markets and our virtual ADC solution in their emerging markets where they have a smaller but growing footprint and need to quickly scale and reliably spin up new ADC instance..

Next, a wireless solutions provider replaced their existing Cisco ACE equipment with our high-end Thunder ADC solution to future proof their network. For this customer, robust features, ease of integration and all-inclusive pricing were the key factors in selecting A10. .

Additionally, a service provider in the Middle East selected A10 for its CGN solution. This customer's primary concerns included security, performance and reliability, and their current equipment could not meet their needs. They chose A10 because our solution significantly outperformed the competition..

Over 3,100 customers now rely on A10 for their mission-critical networking needs. And we have noted previously, once a major customer purchases our products, we generally see both frequent and sizable repeat purchases..

One of our leading U.S. broadband customers that use our ADC solution in a few of its data centers chose to deploy our Thunder Series ADC solution in all their regional data centers across the country, replacing the incumbent. And one of our marquee Internet customer selected our ADC solution for their new data center.

We are very proud of the fact that although this customer had a dual-vendor environment in its existing data center, only A10's ADC solution is being deployed in their new data center because of the performance and flexibility of our platform and our solid track record of customer support..

These are just a few example of the many customers that continue to turn to A10 to meet their network performance and security challenge for today and tomorrow. .

Given this is our first earnings conference call and we're likely to have new investors joining us, I would like to take a few minutes to discuss our differentiated technologies and why customers are moving to our disruptive platform at this rapid pace..

Our next-generation application networking platform leverage the latest technology to deliver a new level of scalability and performance, scaling from megabit to terabit of throughput.

We offer a portfolio of application networking appliance solutions that are all based on ACOS, our next-generation software platform that we have built over the past 8 years. ACOS includes our proprietary shared memory architecture that delivers 2x to 5x the performance of our competitors.

And aFleX is a powerful and flexible feature in ACOS that gives our customers the ability to customize and modify feature to meet their needs..

We have leveraged the power of ACOS to launch 3 stand-alone solutions that address 3 different mission-critical application networking needs. We started with our ADC solutions that optimize network and data center performance. In response to customer needs in 2010, we leveraged the ACOS platform to develop our standalone, carrier-grade CGN solution.

This standalone appliance gives our customers the ability to support an increasing number of mobile devices and subscribers, as IP address availability is becoming scarce. .

More recently, we extend our ACOS platform again to introduce our standalone threat protection , TPS, that is deployed at the perimeter of the network. This standalone security solution provides realtime protection from large-scale DDoS attacks..

Our ACOS platform enable customers to deploy our solutions on a variety of form factors, including physical or virtual appliance.

Whether the customer buys our ADC solution, our standalone CGN solution or our standalone TPS solution, with A10's all-inclusive pricing model, they have access to the full feature set within each solution at the time of purchase. We believe our customer-friendly license model is a key differentiator for A10..

We plan on continuing to leverage our ACOS platform to develop new products in the new segments of the $12-billion application networking market. This is an essential component to our growth strategy. Additionally, we plan on investing in our go-to-market engine in the U.S. and internationally.

We believe this investment will help increase our number of sales opportunities. And given that we have a very high win rate, we are confident that this will translate to new customers and long-term revenue growth..

In summary, we delivered a very strong first quarter and achieved our third consecutive quarter of revenue growth. The superior price performance and flexibility of our application networking platform, our customer-friendly business model and our outstanding customer support are fueling our success.

We believe we are in a very strong position to continue our growth, and we have never been more excited by the opportunities we see for A10..

With that, I'd like to turn the call over to Greg to review the details of our first quarter financial performance and second quarter guidance.

Greg?.

Thank you, Lee, and thanks all of you for joining us here today. Our continued execution of our growth strategy led to strong first quarter results, delivering robust growth and a solid gross margin. First quarter revenue grew 55% year-over-year and 8% sequentially to achieve record revenue of $45.7 million.

Our sequential growth this quarter is notable as the strong demand for our products in Q4 of '13 and Q1 of '14 offset the normal seasonal trends that we can often see in the first quarter of the year. .

Product revenue was $36.4 million or 80% of first quarter revenue, up 57% in the prior year and up 9% quarter-over-quarter. Service revenue was $9.3 million or 20% of revenue, up 48% year-over-year and 7% from Q4 2013.

Nearly all of our service revenue is from ongoing maintenance and support contracts and grows as the installed base of our product grows..

Our deferred revenue, which primarily consists of maintenance to be recognized in future periods, grew 7% sequentially to a record $43.9 million..

From a geographic perspective, we generated robust year-over-year growth in all of our key regions, including the U.S.; Japan; Asia Pacific, excluding Japan; and EMEA. Revenue from the United States grew 72% year-over-year and represented approximately 40% of first quarter revenue. Japan represented 38% of total revenue, growing 40% year-over-year.

And APAC represented 9% of revenue, up 69% year-over-year. EMEA revenue more than doubled over Q1 of '13 and was 9% of total revenue..

Enterprise customers represented approximately 44% of revenue in the quarter, with the remaining 56% of revenue from service providers. The vertical mix of our revenue this quarter reflects the strong service provider component of the Q4 backlog. We expect service provider revenue in Q2 to be closer to 50% of total revenue..

Moving beyond revenue, as we've previously noted, all further metrics discussed on this call are on a non-GAAP basis, unless expressly stated otherwise..

First quarter gross margin increased to 78.2%, in line with our historical trend and up 450 basis points from the 73.7% reported in Q4 '13 and up 40 basis points over Q1 of '13. Product gross margin was 79.6%, also in line with our historical trend of 77% to 80%, and services gross margin was 72.7%..

On the expense side, sales and marketing expense was $20.7 million compared with $20.5 million in Q4, which had included year-end commissions. On a percentage basis, sales and marketing expense was 45.2% of revenue, a 334-basis-point decrease from Q4 of '13..

In Q1, R&D expense increased to $10.7 million or 23.5% of revenue, which was in the middle of our historical range over the past 5 quarters..

G&A and litigation expense combined was approximately $6.9 million or 15% of total revenue compared with $5.7 million or 13.6% of revenue in Q4. The increase in G&A expenses is primarily attributed to costs associated with our IPO and incremental costs associated with being a public company.

In total, non-GAAP operating expenses were $38.3 million or 83.7% of revenue..

First quarter non-GAAP operating loss was $2.5 million. Our non-GAAP net loss in the first quarter was $3.3 million. GAAP net loss in the first quarter was $5.1 million. Using a pro forma share count of 51.3 million shares, our non-GAAP net loss per share equates to $0.06 and a GAAP net loss of $0.37 per share based on 13.9 million shares..

Before moving to the balance sheet, I would like to discuss our non-GAAP operating model. Our primary near-term focus is to significantly grow our top line in order to capitalize on the market opportunity at hand. To help foster this growth, we are aggressively investing in both our go-to-market engine and our product portfolio.

Some of the investments we have made in these areas are reflected in our growing team. Over the past 2 quarters, we expanded our sales and marketing and engineering teams by nearly 100. And in the near term, we plan to continue our aggressive expansion.

However, in the long term, we expect to work towards achieving non-GAAP operating margins in the 21% to 25% range.

And under this non-GAAP target plan, we would expect gross margin in the 78% to 79% range, sales and marketing expenses in the 31% to 34% range, R&D expenses to be in the 15% to 18% range and G&A and litigation expenses to be in the 7% to 9% range..

Now moving to the balance sheet. At March 31, 2014, we had $122.1 million in total cash and equivalents, up from $20.8 million.

This includes $124 million in proceeds, excluding commission and expenses from our initial public offering, offset by approximately $3 million cash used for operation and a paydown of $20 million on our revolving credit facility.

While we paid off the entire amount outstanding on our credit facility, it remains active, and we have the ability to draw on it should we decide to do so in the future..

We ended Q1 with $38.8 million of net accounts receivable, up from the Q4 '13 balance of $37.7 million. Average days sales outstanding were 76 days, a decrease from 80 days in Q4..

Moving on to our outlook. We are entering the second quarter with solid momentum driven by growth in our pipeline and strong interest in our new products. We currently expect Q2 revenue to be in the range of $46 million to $48 million. This represents 53% to 59% growth on a year-over-year basis.

We expect non-GAAP net loss to be between $0.07 and $0.09 per share using 59.6 million shares on a basic and diluted basis. In closing, we are executing well on our strategy and growth plan, we delivered a fantastic quarter, and we are optimistic about our future opportunities. .

And with that, I'd like to open up the call for your questions.

Operator?.

[Operator Instructions] And our first question comes from the line of Tal Liani with Bank of America. .

I have 3 questions. First, do you provide the revenue breakdown between ADC, TPS or security and CGN? And second, what was the growth in service providers? You just said it was strong and it reached 56% of revenues versus kind of 50% normalized, but do you have the growth? And the third is related to the second question.

We've seen a few companies that had strong growth in service providers in the first quarter, which is atypical. This is supposed to be a weak quarter. And that most of them is because of AT&T. And I'm wondering if you had any concentration on your side, if you had any concentration of customer within the service provider growth. .

Hi, Tal, this is Greg. Thank you for joining us today. So I'm going through your questions in order here. On the ADC, CGN, TPS, we are not breaking those out separately as revenue streams.

Just within the quarter, we have seen strength in -- strength both in sales and in pipeline across those products, so we don't expect to be breaking this out in the future.

As far as service providers go, I think that in the first quarter, we did see strength from the service providers, both in deals that we booked within the quarter, as well as the amount of backlog we carried out of Q4 into the quarter.

So what we saw in the growth there was driven partly by the new transactions, but also by transactions that our service provider customers had committed to late in Q4. So the growth rate on service providers was a little over 100% quarter-over-quarter and 66% year-over-year service providers.

We do typically see some strength in service providers in Q1 because it is the Q4 in the Japanese market. .

And there was any concentration?.

Yes, I mean, in the service provider market, we do see some large transactions. So if we looked at our 10% customers, you would find service providers within that environment, yes. .

Last question is your security. You announced the security product, but you did have revenues for security from a big customer already in 3Q last year.

First, can you give us an update on this customer, if there was any strength this quarter, are there any repeat orders or anything you can discuss? And second, how soon do you expect the security product to ramp into -- the new product that you discussed in your press release to ramp into the next few quarters?.

Okay. Tal, this is Lee. We announced the TPS product in Q1, and we just released the product today. So the -- in terms of the customer, we have one large order in Q3 last year with a customer. We continue engage with the customer. But due to the product just released today so we did not have -- see any revenue in this quarter from that customer.

But we expect the -- we are seeing a strong and growing interest, a very strong pipeline and positive initial feedback on the TPS product. So we do expect that within 4 to 6 months, we should start to see a good -- these deals already coming in. .

And, Tal, I misspoke on the quarter-to-quarter. It was 58% service provider quarter-to-quarter. .

66% year-over-year still?.

Yes. And 58% quarter-to-quarter. Yes. .

Our next question comes from the line of Katy Huberty with Morgan Stanley. .

First question, midpoint of guidance assumes roughly 26% sequential growth in enterprise, which is pretty impressive given some of the guidance we've seen from other enterprise companies.

Can you just talk about whether you think that's normal seasonality or if you're seeing some acceleration in traction with new customers or new products? Then I have a follow-up. .

So we are seeing a significant traction with both new and existing customers as we brought the Thunder Series product to market, and we're seeing great both interest and adoption of that product. And we're seeing very strong pipelines leading into Q2.

So everything that we're seeing in the market is consistent with the guidance and the expectations we have for Q2. .

And then can you just walk through the major changes to the partner program announced last week and talk about how much of an impact and timing of an impact that we should expect from that rollout?.

Yes, well, let me pass it over to Ray Smets to address that question. .

Yes, sure. We just announced a new partner program. It's a new three-tier program that replaces our prior program, and it's what you would typically expect of a company of our size. Basically, rewards partners that deliver a higher degree of revenue with greater margins and discounts.

What's really unique about this program is that it adopts -- it moves our existing partner base to the new program, where we expect to see those existing partners deliver better revenues for us over time. We're going to deliver greater enablement, better certifications and additional support that helps those partners get more productive.

The other half of this program is it was really well received by the partner community, and we anticipate recruiting new partners to the program as a result. And we would leverage our enablement and our support and the certifications process to make them productive as quickly as possible.

So this is part of our strategy to grow our business and get access to the market, and we're super excited about this product launch -- or this new partner launch. .

And it's in effect right now so we should see the impact in the June quarter?.

Yes, well, it does take a little time for traction to be made with a partner program like this. So the new partners will see an, hopefully, an immediate benefits. And then as we begin to recruit other partners in the program, we should see benefit to our business over time, probably over the next 6 months to 9 months. .

And our next question comes from the line of Rod Hall with JPMorgan. .

Just wanted to start off with Japan. I guess we've heard the F5 talking about strength in Japan. Now you guys are talking about a pretty good quarter in Japan as well. I wonder if you could just comment on the demand dynamics in Japan, what's going on there, and also the competitive dynamics a little bit, and then I have a follow-up. .

Yes. Rod, this is Lee. Let me answer that. I think we saw the revenue grew 40% year-over-year and also more than doubled from Q4. So we are seeing a very strong demand in Japan. I think the numbers speak for themselves. We definitely have a very strong position in Japan, very tight relationship with partner and customer in Japan.

As a matter of fact, I was in Japan last week -- I mean, 2 weeks ago, a meeting with a customer, a partner and with our User Conference. Our User Conference actually had the largest turnout and, in general, very upbeat. .

Okay. Great. Also, I wanted to ask a little -- just maybe a question, Greg, on the EBIT margin performance. I mean, that was better than we had anticipated. And I just wondered whether you think, Greg, you can hold the OpEx line kind of stable as revenues are growing a little bit faster, maybe.

So I guess I'm curious on what the -- what you think the EBIT line looks like over the next year or so, maybe we end up with breakeven EBIT sooner than maybe you had originally anticipated a few months ago. .

Rod, not necessarily. We're really focused on growing the top line at this point and think there's a great market opportunity out there. So I think over the next year or so that you'll see variation in the EBITDA line as well as in kind of the operating margins just as we -- as we invest.

We look at our hiring patterns, we tend to focus on Q4 and Q1 in our sales teams, and so you'll see some additional expenses in those quarters. So we're not really going to guide towards any level of consistency in that number at this point. .

Of our next question comes from the line of Mark Sue with RBC capital. .

I'm trying to get a sense of just the new products and the range of new products, and what percentage of your customers are actually just taking the regular [indiscernible], which are taking the carrier-grade and the DDoS collectively? How is it -- that is all combining for a collective set, maybe if you could give us any use-case examples.

We're just trying to get a sense of the multiplier effect. .

Mark, can you repeat that question? It broke up a little bit as you were asking it. .

Sure. I'm just trying to get a sense are you seeing an increased number of customers taking a collective set of your products, ADCs, carrier-grade and DDoS as opposed to certain customers very focused on specific end products.

Are you seeing a multiplier effect?.

Mark, this is Lee. Let me just take the DDoS product. I think DDoS product just released today, so we just kicked off the sales activity. Even though the initial feedback has been very positive, we are seeing already a growing interest, we do expect it will take 4 to 6 months to see the initial deals coming in.

So the 100 -- CGN DDoS, we do have a customer taking our high-end Thunder Series, taking our higher-end Thunder Series in North America for their CGN deployment, including some of the security function. .

I see.

Would you say a lot of the initial interest is from existing customers or a new set of customers for some of the new products?.

Yes, actually, from both. We are absolutely seeing a lot of our current customers are very interesting in our DDoS solution. We also win with many new customers. They come to A10, contact A10. I was just recently in Asia. We had some international partner actually approaching us because of DDoS solutions we are going to offer. .

I see. That's helpful.

And then lastly, just on this legacy Cisco ACE replacement, any thoughts of quantifying that and where we might be in terms of sunsetting that opportunity?.

Ray, can you take that question?.

Yes, sure. Hey, Mark, this is Ray. I guess, the good news is we have -- to opportunity for us is really getting to the table. When we get to the table, we tend to have a very high win rate in any deal.

The good news is we are winning some very substantial ACE replacements as well as winning back replacement strategies for other vendors that are in the incumbent position. So although we're not breaking down the numbers specifically, our win rate tends to be above 70% when we're in the deal, and a number of those are ACE replacements. .

Our next question comes from the line of Brent Bracelin with Pacific Crest. .

A handful of questions here. I guess the first one, we'll start with a little housekeeping.

10% plus customers, did you have any in the quarter? And if so, who was it and what percentage of revenue was it?.

Hi, Brent, it's Greg. So yes, we did have 3 in there. The percentage will be listed out in the Q and S filed, but we have -- in round numbers, we have 1 at 13%, 1 at 12% and 1 at 11%. We're not disclosing the names quite yet. .

Okay. Look forward to the filing there. And then follow-up on the Cisco ACE win. You mentioned at a wireless customer.

Was that a Tier 1 wireless customer or was that kind of more Tier 2?.

That was a Tier 2 wireless customer in that case. .

Okay.

And any color on Geo, or is that too specific?.

Yes, that was a Tier 2 in North America actually. .

Tier 2 in North America. Very helpful. And then last question for me is, really, on the enterprise part of the business, clearly, you had a nice backlog going into this quarter on service provider. Enterprise still is relatively healthy, albeit easy compare, up 78% year-over-year.

Your guidance does imply you're pretty optimistic about continued strength in the enterprise.

Question here is, really what's, driving the momentum for you on the enterprise side? Are you seeing a mix shift to 10 gig upgrades, is this tied to an increasing desire by the enterprise to drive higher SSL traffic offloads? Any color on what's driving the strength on the enterprise side would be helpful. .

I think there are multiple factors. One is really from the ACOS platform. I think the platform offer a tremendous, I think, price performance, flexibility and really rich feature set. So enterprise, as we know, every customer, they demand different features.

And we are also very agile to really -- to do really quick feature release for specific enterprise customers. You have to really invest in the sales engine. And we have been investing a lot in the sales and marketing over the last 6 months. So we are seeing some impact of our investment paying off. .

Okay.

So it sounds like the -- just improving sales productivity of those investments that you made 6, 9 months ago is really starting to pay off? Is that the #1 reason? Is there any technology kind of driver you that you see out there that's contributing to the acceleration and momentum in enterprise?.

Yes, from the technology, it's really about the platform, right? The platform is really gaining traction within enterprise. Our platform is very, very flexible, very reliable, and we're able to build a reputation of the product itself is super reliable. That's what many enterprise are looking for. The other thing is really about performance.

Both are easy to manage. .

You know, Brent, I think, the other thing to add to that is that from a product perspective, when we moved from ADC to CGN, we had a second product out there that our service provider products could buy. And we've talked about our land-and-expand strategy, somebody. When somebody buys, they move into the second product.

With DDoS, we now have a product that will be coming out where our enterprise customers have a second product from the A10 portfolio that they can purchase. So we have a whole new product family that will be moving us into enterprise as well. .

Our next question comes from the line of Ittai Kidron with Oppenheimer. .

Congratulations, guys, on a great start as a public company. Greg, I wanted to dig a little bit into some the numbers.

When you talked about 200 enterprise -- or customers additions, I'm sorry, in the quarter, can you give us some context what it was in the fourth quarter or the same quarter last year, just so we get a sense of the acceleration there?.

Let me, as I pull those numbers up, Ittai, I will say that for the year last year, we added approximately 1,000 customers over the course of the year. And as you know, Q1 and Q2 were like quarters for us last year, so that was fairly back-end loaded. So in just a second, we can have a number there.

If you had a second question, we can do that and then come back. .

Yes, so do you -- how relevant -- if we just look at the enterprise -- I understand that the service provider is very lumpy. You can have $4 million, $5 million orders and then on much smaller follow-on orders as you go.

But when you look at the enterprise side, can you talk about some deal sizes and what's been the trend over there and how do you anticipate that to move forward now again that your portfolio and your ability to sell more into the same customer is developing?.

Sure. Let me preface this, and then I'll turn it over to Ray. We and the -- when we got to doing the roadshow and described land and expand as we've showed how our top customers, if they buy it, and they're buying in 80% of the quarters after initial purchase and that they're buying more than 8x additional product.

And we see that pattern is representable in our enterprise customers as well as our service providers. So in some of the examples that Lee has described in the meeting -- or earlier in the call, you have seen how they would transact in expanding the footprint of A10 product across the enterprise. So they go 1 data center to multiple.

So we do see that as a pretty consistent pattern. I'll turn it over to Ray. He can talk a little bit some cases on that and some other metrics. .

Yes, so Ittai, this is a -- it's a bit of a mixed bag, very hard to get into all the details here, but obviously, what you're detecting here is our service provider customers need to grow very nicely, and they add a significant amount of million-dollar deals and deal size to our overall average.

But we are moving down into the enterprise market more effectively. We sell large enterprise, but we also are going down market and our channel program will actually address more of that market over time. Overall, the trend is going up in terms of deal size.

So -- and I think -- I don't know if we actually provide that publicly, but we're actually seeing a very nice trend northward in terms of average deal size on a quarterly basis. .

And that would actually be reflective of what we see when we look at the customer numbers. To go back to your first question, last year, Q1, we added 202 customers and in Q4, we added 245 new customers. .

Got it.

And then on the gross margin, Greg, as we move into the next quarter, given the change in mix that you're anticipating with regards to enterprise versus carrier, does that, generally speaking, have any impact directionally on margin?.

Generally not. When we look at it, our near-term margins, our expectations are still in the 77% to 78% range. .

[Operator Instructions] And our next question comes from the line of Ehud Gelblum with Citi. .

Okay, so a couple of additional housekeeping questions, if I could. Greg, can you give us a breakdown of CGN revenues versus ADC in the product side? I'm assuming the DDoS was zero this quarter.

Is that the right assumption?.

Well, so I'll answer half of your question with data. Yes, with -- the TPS DDoS product is just now available for shipping as of today, so it does not contribute to revenue beyond that first large customer that we had. But beyond that, we're not breaking down the -- our revenues by the CGN, ADC, TPS at this point. .

Okay.

Can you give us a split between Thunder and AX?.

Again, we're not providing that breakout, but I will say that as we see new business coming on, there's a sizable move towards the Thunder platform due to the performance that it brings and the price performance that comes along with it. So we're seeing that being adopted pretty aggressively in the market.

I think as we had mentioned at least previously at one point that part of the backlog that we carried out of Q4 was due to more demand than we had expected in terms of some our high-end Thunder products. .

In general, the high-end Thunder products are performing really well. .

Yes, will it be safe to assume that going forward, 3/4 of revenues is basically going to be Thunder or more?.

Yes, I don't think we have that level of detail to provide. .

Okay.

Did you -- I may have missed it, but did you give a split between direct and channel and what your goals are between those 2?.

We have not, but I can give you some directional indicators there. We are primarily a channel business. Ray talked about expanding the channel. That's about getting more productivity out of the channel. But currently, greater than 90% of our transactions go through the channel, not quite the same break on dollars.

There's some major customers who prefer to work with us directly. But when you think about how we will generate incremental leverage in the marketplace, a good portion of that is driven by our channel strategy that Ray described earlier. .

Right. That was more for the dollar number.

Would that be closer to around 2/3 and roughly staying there?.

What is the question?.

I'm sorry.

The split, the percent channel, that is on the dollar basis not on the actual per unit customer basis?.

Yes, we won't be breaking that out, but we will talk about it just in terms of -- from a transactional perspective. That's one of the things that drive -- the thing that gets thrown off is that the channel business tends to be, as your numbers would illustrate there, tends to be how you go after more of the mass-market transactions.

And that's where we see, as the product moves to be more enterprise oriented, we see the channels becoming greater contributor to that piece of the revenue stream primarily. .

Great. Okay, helpful. Question on the guidance. Assuming your guidance of the midpoint is up a couple of million basically from what you just did in Q1, it sounds as though with the TPS product actually having some backlog and now being ready to ship, that you'll sell a little bit of TPS.

I'm not quite sure exactly how much you're anticipating for next quarter.

But is the implication therefore that ADC is sort of flat to down next quarter on a sequential basis?.

No, I think the -- for the DDoS TPS product, we expect it will take 4 to 6 months, due to this new product. Even though the initial feedback has been very positive, [indiscernible] of 4 to 6 months. So it should [indiscernible] Q2. .

Okay, so all the growth next quarter in Q2 is TPS -- I'm sorry, is CGN and ADC. Helpful. .

You will see a growing pipeline in TPS. .

Okay. That's very helpful.

Last question, big picture on the -- now that you've been out in public for a little while, have you seen any competitive response either on pricing or any other way from your main competitors, F5, Citrix, Radware?.

We have not noticed anything in the marketplace, no. .

And we have a follow-up question from the line of Mark Sue with RBC capital. .

Gentlemen, if I put things in a historical perspective, a year ago, there was some concern whether or not the ADC market was really growing. Today, you're guiding for revenues to reaccelerate to almost 60%, then you have new products coming also as well.

If we look into the future maybe a year or so, should we think of A10 more as a platform delivery system? Conceptually, are there other things that customers are asking for, which you can actually layer on top? Just kind of the thought process of the things in the future. .

I think the -- yes, Mark, this is Lee. I think we are -- ADC is a really established but very healthy market. But our growth rate in ADC is definitely much higher than our competition. The -- our partners, I think the, really, mission-critical area, the platform has always been a strong selling point.

With additional feature we put in the ADC such as SSL Intercept, I think that will drive channel the new business. So we're definitely seeing through platform, the feature, the performance, the scalability and flexibility, all this contribute to our success in the ADC market. .

And I'm showing we have no further questions at this time. I would now like to turn it back over to Lee Chen for any closing remarks. .
