Good afternoon. Thank you for attending today's second quarter 2022 earnings conference call. My name is Tamia, and I will be your moderator for today. All lines will be muted during the presentation portion of the call with an opportunity for questions and answers at the end. If you would like to ask a question, please press star one on your telephone keypad. It is now my pleasure to pass the conference over to our host, Rob Fink of FNK IR. Please proceed.
Thank you, operator, and thank you all for joining us today. This call is being recorded and webcasted live, and it may be accessed for at least 90 days via the A10 Networks website at a10networks.com. Hosting the call today are Dhrupad Trivedi, President and CEO, and CFO, Brian Becker. Before we begin, I would like to remind you that shortly after the market closed today, A10 issued a press release announcing its second quarter financial results. Additionally, A10 published a presentation and supplemental trended financial statements. You may access the press release presentation and the trended financial statements on the investor relations section of the company's website.
During the course of today's call, management will make forward-looking statements, including statements regarding projections for future operating results, potential revenue growth, industry and customer trends, focus on investment in go-to-market strategies and infrastructure, capital allocation strategy, M&A opportunities, supply chain constraints and expectations, its positioning, its repurchase and dividend programs, and market share. These statements are based on current expectations and beliefs as of today, August second. These forward-looking statements involve a number of risks and uncertainties, some of which are beyond the company's control, such as the potential impact of COVID-19 on its business and operations that could cause actual results to differ materially, and you should not rely on them as predictions of future events. A10 does not intend to update information contained in these forward-looking statements, whether as a result of new information, future events, or otherwise, unless required by law.
For a more detailed description of these risks and uncertainties, please refer to A10's most recent 10-K. Please also note that with the exception of revenue, financial measures discussed today are on a non-GAAP basis and have been adjusted to exclude certain charges. The non-GAAP financial measures are not intended to be considered in isolation or as a substitute for results prepared in accordance with GAAP, and they may be different from non-GAAP financial measures presented by other companies. A reconciliation between GAAP and non-GAAP measures can be found in the company's press release issued today and on the trended quarterly financials statements that was posted on the company's website. With all that said, I'd like to turn the call over to Dhrupad. Dhrupad, the call is yours.
Thank you, Rob, and thank you all for joining us today. The second quarter was another strong quarter for A10. It was our tenth quarter in a row of meeting revenue and EPS expectations. I'm proud of the team we have built at A10 and the significant operational improvements we have driven together, leaning into our proprietary security-led solutions, transitioning away from legacy offerings, and positioning A10 as a recognized leader in one of the most important market catalysts in technology today, network security. A10 faces the same market conditions, supply chain challenges, and economic realities as our peers. Despite COVID, recessionary conditions, currency headwinds, and a global supply chain crisis, we have established a clear and durable track record of success. Central to this success has been our focus on the network security needs of our customers and our diversification efforts.
We sell to two main customer groups, enterprises and service providers. Within these two groups, our business is aligned with two secular tailwinds, infrastructure and cybersecurity. In the first half of 2022, the economy had a disproportionate impact on this mix. Cybersecurity continues to grow, and the global geopolitical events have only served as more of a catalyst for this growth. Simultaneously, infrastructure build-out requires capital expenditures, which can be impacted by interest rates and inflation unless it is linked to revenue generation. Like our peers, our visibility with small and mid-size enterprises, especially related to infrastructure build-out, is not as clear as it was exiting 2021. However, cybersecurity solutions are being prioritized even amidst economic challenges, and especially by service providers for whom network security and reliability is a business essential.
The net result for A10 is performance in the first half of the year that exceeded published expectations, further strengthening our confidence in our full-year outlook and ability to invest for future growth. Driven by continued adoption of our proprietary security-led solutions, revenue increased 14.9% year-over-year. Our gross margin was better than 80% despite continued supply chain challenges and input cost pressures, driving higher levels of operating income, EBITDA and net income. During the second quarter, we achieved our rule of forty goal with revenue growth of 14.9% and adjusted EBITDA margins of 26.4%, representing a combined 41.3%.
We ended the quarter with nearly $167 million in cash or $2.13 per share, even after returning more than $7 million to shareholders in the form of share repurchases and a cash dividend. We have a fortress balance sheet positioning us to thrive if the economy slows and creating incremental opportunities as relative valuations reset. We also have a proven business model with our bottom line growing faster than our top line. Building upon a strong legacy, we have built security solutions into every facet of our portfolio. As discussed before, product mix improvement is an important metric for A10. Standalone ADC continued to decline as a percent of overall revenue, even as consolidated top line grew 14.9%, demonstrating the progress we have made in transitioning to a security and infrastructure solutions company.
Today, A10 focuses on customer-centric innovation and a solution-based sales approach, delivering tangible business value and industry-leading total cost of ownership for our clients, regardless of whether the solutions are deployed on-prem, in private cloud or public cloud. The cybersecurity threats only grow in magnitude, frequency and sophistication. The war in Ukraine and the global diplomatic response has created new threats and exacerbated old ones. Our advanced machine learning solutions continue to identify and mitigate new challenges, such as the emerging LDAP amplification threats. Our current solutions identify and cover a significantly broader spectrum of threats, including setting the standard for identifying and isolating DDoS attacks. A10's technology strengths and infrastructure allow us to do this efficiently while providing best-in-class cybersecurity integrated with network traffic flow. CIOs are increasingly focused on security first, and A10 is capturing share because of our differentiated approach to solving our customers' problems.
Let me highlight some key areas of progress within our business. Our revenue growth continues to be driven by our proprietary security-led product revenue, which on a trailing twelve-month basis, is now up 26%, backed by secular tailwinds. Overall product revenue, which is a leading indicator of future recurring service revenue, increased 21% versus Q2 of 2021. From a geographic perspective, revenue from the Americas grew 33.7% year-over-year to $38.6 million, reflecting our investment in commercial initiatives in the Americas and strong demand for our solutions. EMEA revenue increased 10.5% year-over-year. Asia, including Japan, was essentially flat on a constant currency basis, exceeding our expectations. Inclusive of the significant foreign currency impact, APJ revenue decreased 7.1% year-over-year.
Our diversification continues to provide a resilient foundation as different regions navigate macroeconomic and geopolitical headwinds. We continue to focus our investments in growth opportunities, including expanded and new capabilities in cybersecurity. We also continue to partner on hybrid solutions, enabling our customers to navigate their own technology roadmaps amidst the current economic climate. A priority within these investments is improving our ability to cross-sell solutions to our customers while enabling them to reduce overall CapEx and OpEx. Our own OpEx increased 11% year-over-year, demonstrating these investments. Over the past year, our product revenue growth rate with existing customers has consistently exceeded our target growth rate, demonstrating our ability to successfully leverage our strong install base and bolsters our confidence in delivering 10%-12% consolidated growth compared to the prior year. We are committed to maintaining a disciplined, flexible, and opportunistic capital allocation strategy.
The recent economic conditions have impacted valuations across the board, and while we will continue to demonstrate rigor in evaluating potential uses of shareholder capital, the current market conditions are only likely to provide increased opportunities. Supply chain issues continue throughout our industry. To date, A10 has been able to navigate these conditions as evidenced by our gross margin improvements and our consistent ability to deliver products to customers. Our year-to-date performance reinforces our expectation that we can achieve our full year targets of revenue growth of 10%-12% year-over-year and EBITDA in the range of 26%-28% of revenue for 2022. We have taken the current external environment into account and have identified levers in our business to achieve our targeted bottom line performance for the year.
With that, I'd like to turn the call over to Brian for a detailed review of the quarter. Brian?
Thank you, Dhrupad. Second quarter revenue was $68 million, up 14.9% year-over-year, the second highest quarter revenue in our history. Product revenue, which is a lead indicator for future revenue, was $41.5 million, representing 61% of total revenue, up 20.7% year-over-year. Services revenue, which includes maintenance and support revenue, was $26.5 million, or 39% of total revenue. Moving to our revenue from a geographic standpoint, as Dhrupad mentioned, revenue from the Americas, including Latam, was $38.6 million, up 33.7%. Revenue from EMEA was $7.8 million compared to $7.1 million last year, up 10.5%.
Revenue from Asia, including Japan, was $21.6 million, down 7.1% compared to $23.3 million in the second quarter last year, which is exclusively due to the depreciating yen-to-dollar currency exchange rates. As you can see on our balance sheet, our deferred revenue is $127.9 million as of June 30, 2022, up 10% year-over-year. Recurring revenue, defined as support and subscription revenue, grew 7% year-over-year to $29.2 million in the second quarter. With the exception of revenue, all the metrics discussed on this call are on a non-GAAP basis unless otherwise stated. A full reconciliation of GAAP to non-GAAP results are provided in our press release and on our website. Gross margin in the second quarter was 80.6%.
As Dhrupad mentioned, we continued to successfully mitigate the impact of industry-wide global supply chain constraints and input cost increases. Non-GAAP operating expenses in Q2 were $38.7 million, compared to $35 million in the second quarter last year, reflecting increasing investment in our growth priorities, including cybersecurity technology and commercial execution. We reported $16.1 million in non-GAAP operating income compared to $11.1 million in the year-ago quarter. Adjusted EBITDA was $18 million for the quarter or 26.4% of revenue. Non-GAAP net income for the quarter was $13.4 million, or $0.17 on a per share basis. Diluted weighted shares used for computing non-GAAP EPS for the second quarter were approximately 78.3 million shares compared to 79.3 million shares in the year-ago quarter.
On a GAAP basis, net income for the quarter was $10.4 million or $0.13 per share, compared with net income of $6.6 million or $0.08 per share in the second quarter last year. Turning to the year-to-date results, revenue for the first six months of 2022 was $130.6 million, compared to $114 million in the same period last year, up 14% year-over-year. Product revenue was $78.5 million year to date, up 21% from $64.9 million. Services revenue was $52.1 million, up 6.1% from $49.1 million. Year to date, gross margin was 80.4%, which was driven by favorable product and geographic mix.
Non-GAAP operating income was $27.8 million year to date, up 26.7% compared to $21.9 million last year. Adjusted EBITDA year to date was $31.5 million or 24.1% of revenue. Non-GAAP net income was $23.4 million, or $0.30 on a per share basis. Weighted shares used for computing non-GAAP EPS for the first six-month period were approximately 78 million shares. On a GAAP basis, year to date net income was $16.8 million or $0.21 per share. Turning to the balance sheet. As of June 30th, 2022, we had $166.8 million in total cash and cash equivalents, effectively unchanged from the year ago period.
Year to date, we have repurchased 2.4 million shares or $31.8 million worth, and have issued $7.7 million in cash dividends. We continue to carry no debt. In addition, the board has approved a quarterly cash dividend of $0.05 per share to be paid on September 1, 2022 to shareholders of record on August 15, 2022. In total, we returned more than $39 million to shareholders in the first half of 2022 between share repurchases and dividend. As Dhrupad mentioned, we are now well-positioned to achieve our full-year revenue target of 10%-12% growth year-over-year and full-year adjusted EBITDA margin of 26%-28% of revenue. I'll now turn the call back over to Dhrupad for closing comments.
Thank you, Brian. I'm proud of A10's ability to continue to perform better than the overall industry, both in terms of growth and in terms of navigating external challenges. Our proprietary security-led solutions are enabling us to capture market share and expand our customer base. We remain well diversified in terms of product mix, regional mix, and customer mix, enabling a more durable model in spite of macro headwinds. Operator, you can now open the call up for questions.
Absolutely. We will now begin the question and answer session. If you would like to ask a question, please press star followed by one on your telephone keypad. If for any reason at all you would like to remove that question, please press star followed by two. Again, to ask a question, press star one. As a reminder, if you're using a speakerphone, please remember to pick up your handset before asking your question. We will pause here briefly as questions are registered. The first question comes from Hamed Khorsand with BWS Financial. Your line is open.
Hi. Could you just talk about the competitive landscape, given the stronger US dollar, and how that could be impacting or benefiting you in some of your international markets?
Sure. Yeah, Hamed. Good question. If you look at our global mix, right, of course, our strongest growth region was North America, in terms of currency, that doesn't affect us. When you think of our business in Japan, clearly as the yen exchange rate has gone from something like 105 to 136, it created a headwind, and we were able to overcome that by performance in North America. In Europe, our business is conducted mostly in USD-denominated transactions. While it creates a little bit of headwind in terms of higher local currency rate, it was not a material impact for us so far.
Okay. Is there any contributing standpoint from the OpEx line given the stronger dollar?
Not a significant impact from that perspective because obviously the local sales and marketing and other offices are, the OpEx is in local currencies as well, so not a meaningful impact for us, positive or negative.
The last question was, could you just talk about your sales funnel looking out? How much clarity do you have, and do you see any customers pushing out, you know, potential orders?
Yeah, no, good question. I think, you know, we of course monitor multiple metrics to think of demand and our outlook on it. We see a little phenomenon where, because a lot of the lead times from several of our, you know, companies in the space are extended, dramatically. As it relates directly to A10, we are not seeing customers deliberately pushing out, you know, meaningfully, right? There is some push and pull.
Of course, with war in Europe and things like that, the sales cycles are a little bit longer, but we don't see a deliberate choice where somebody's saying, "We will put this off for six months or nine months." I think, Hamed, I would relate it back to, because our solutions are directly linked to customers' revenue generation or maintaining quality or performance of networks versus just modernization, I think, you know, we see those as being different categories than discretionary IT spending, which may be more likely to be pushed out.
Okay. Thank you.
Thanks.
Thank you. The next question comes from Christian Schwab with Craig-Hallum. Please proceed.
Hey, guys. Congratulations on another solid quarter and 10 quarters in a row. Kudos on navigating you know a continued challenging supply chain environment, but kind of a tremendous shift in currency and kind of unprecedented in the yen. When we look at your exposure there and you're talking to customers, et cetera, you know where does the dollar yen conversion rate you know should it moderate back from kind of these you know like a 12% extreme movement in the quarter you know to make your products you know competitive or not you know maybe possibly delayed if they actually were?
Yeah. Good question. I think, you know, I would say even as it relates to Japan, we did not see delays or push-outs because of currency concerns per se. I think it's more, because the local transactions are in yen, so, you know, it's more that we were able to absorb that on a constant currency basis, if you will, within our overall growth of 14.9%, right? From a demand perspective, because the local demand is in yen and we are fulfilling it in yen, we don't see that as being something where things are deferred a lot. In fact, you know, our Japan team in terms of yen performance is on track to what we expected. As things moderate out, I think certainly it eases out that headwind for us.
You know, as I mentioned in the script, obviously we are always navigating a lot of things and, you know, we would also appreciate when that kind of tapers out. In the meantime, we look for ways to offset that to still get to where we need to.
Great. Thank you for that. Thank you for the clarity and the set of slides on, you know, product differentiation and, you know, I think an explanation of making it more simpler for some investors to understand, as an analyst who's had to explain it to people. I appreciate that. With that being said, though, can you just give us an update on the competitive landscape and who, you know, you guys are seeing the most often and who you believe your products may stack up best against?
Sure, yeah. You know, I think roughly 2/3 of our sales are to the service provider segment, which includes cloud, telcos, MSOs, and so forth, and 1/3 is enterprise. On the service provider portion on the security products, we would be competing with someone like Arbor Networks, which is part of NetScout. On the core sort of service provider traffic and other features, we would be competing with someone like Juniper, and that landscape really has not changed, I would say, materially from 90 days ago or even longer. On the enterprise side, which is 1/3 of our business, it is predominantly large enterprises, and that would be financial services and other institutions that handle a lot of data and are handling a lot of users and security.
On that segment, our competition would most often be someone like F5 Networks. The way our product is architected is we combine multiple kind of categories of products, which is, you know, a little bit unique, right? Which is true for every company, but so it's not a one-for-one comparison, but those would be the names we would see most often as competitors.
Excellent. Then my last question, I think when you guys were talking about your extremely strong balance sheet and successful buyback program, dividend, et cetera, did you hint or suggest that you may use that to make acquisitions or to look at M&A with valuation multiples in the marketplace coming down to potentially create more capability/scale for your existing customer base, or did I hear that wrong?
Yeah, no, good question. I think you know, as we have said before, and it's still true, is our first priority is investing in organic growth. You can see obviously we are increasing OpEx to fuel faster growth, because that's the most efficient and fulfilling way to grow as well. Second is, of course, you know, return for investors, in addition to everyone else. In that context, we talk about buyback and dividends. I would say the last part for us is we have already, you know, all the whole time, of course, opportunistically looked at ideas that might help us bolster either a product capability or reach a different vertical or customer base. We will continue to do that, but do it in a way that's financially rigorous. You are correct.
I think as things reset, maybe there's more things to evaluate, but our primary focus is really organic growth, and our plan is based on, you know, how we can continue to fuel that growth. Having said that, you know, with that balance sheet, we feel good that we can navigate turbulent times. If something makes sense and is financially disciplined way to do it, we would continue to look at those options as well.
Great. Thank you for that, and congrats on the great execution. Thank you.
Thank you. Thank you.
Thank you. The next question comes from Anja Soderstrom with Sidoti. Please proceed.
Hi, thank you for taking my questions, and congratulations on another great quarter. I'm just curious, on the sales and marketing, it looks like that scaled back a little bit for this quarter. Why is that?
I'm not sure, Anja. Maybe that's on a GAAP basis, but in absolute terms, sales and marketing is up 10% year-over-year, and R&D is up about 11% year-over-year. I think we can tie out later, but we continue to invest more. Sales and marketing is higher, effectively, one, for the higher sales, so cost of sales for the higher revenue. Second is we continue to invest in more solution selling and security-oriented sales. R&D is up year-over-year as we invest more, as I said, in new types of cyber threats and continuing to expand our depth there.
Okay. Sorry, my mistake. Are you adding headcount to capture this stronger growth or you're not meaningfully adding any headcounts?
It's a mix. I think, you know, our growth in sales and marketing is a balanced approach. We focus on better solution selling, expanding more categories with existing customers, selling based on, you know, security and ROIC value proposition, and expecting obviously productivity improvements as well, right? Yeah, we add headcount, but our growth is based on all of those things, and increasing headcount is just one factor. You know, as obviously they ramp up and become more productive, that's positive as well. It's not limited to growing by adding more salespeople. It's doing all those things together.
Okay. Thank you. If you could just remind us again how correlated you are to the service providers' CapEx cycles and where you see the transition to 5G, where we are in that at this point?
I think, you know, for us, Anja, of course, service provider category includes cloud companies as well as telcos and MSOs. For us, obviously we are engaged in many 5G design wins around the world. Obviously that cycle is not as fast as originally a lot of people had expected. But for us, the approach was always a balanced one, where we are engaged with those customers to modernize their current systems as well by doing things like virtualization, offering more security. As they make the investments to move to 5G, we are well-positioned to take advantage of that.
As it relates to correlation with their CapEx cycles, there is some correlation, but, you know, if you think specifically of 5G, the sequence is there's a spectrum sale, then there's a radio build-out, then there is infrastructure, optical backbone build-out, then it's deployment of services. We are well-positioned for that. In the meantime, all those service providers also continue to invest their current CapEx and OpEx for either more security than they used to do, or because they are adding new services or more subscribers, they need to add more capacity to handle that traffic. We participate in those cycles, both existing and new. Security spending is not highly related or correlated to their CapEx cycle. It's more secular phenomenon. Infrastructure build-out is more related to CapEx cycles, right?
as we said, obviously with interest rates and other fears, that is a little more depressed, but security is kind of secular from that.
Okay. Thank you. That was all for me.
Thank you, Anja.
Thank you. The next question comes from Hendi Susanto with Gabelli Funds. Your line is open.
Good afternoon, Dhrupad, Brian.
Hey, Hendi.
Hey there.
Yep. Hi, Dhrupad. I would like to inquire or seek your perspective on the growth between enterprise and service providers. Service providers deliver growth like above 20% for the first half, while enterprise growth is, I'd say, like low- to mid-single-digit.
Mm-hmm. Mm-hmm
Do you expect that growth profile to remain? Or, should there be any catalyst that may, let's say, result in, like higher growth in enterprise and maybe, like lower growth in service providers?
Mm-hmm. Yeah. No, good question. You know, I think as we have mentioned before, we don't try to specifically achieve a certain mix there, but the phenomenon is this, right? In the first half of this year, as I was saying before, service providers continue to have to navigate adding subscribers, new services, and facing new security threats. We continue to make progress with those around the world, whether it's MSOs, telcos, or cloud companies. As it relates to enterprise side, of course, that is the segment where our exposure is mostly to large enterprise, but that is the segment where economic conditions have had a stronger impact. If you look at a lot of the peer groups that we com...
You know, get compared to, obviously, right, they are signaling very low or negative growth in that segment this year. We think that is a macro phenomenon that is impacted by war in Europe, interest rate, inflation, uncertainty, all that kind of issues. We focus within that on verticals where we are more and more differentiated. I think, you know, as the economic environment improves, that number could go up and service provider could be a little slower. We look to achieve that. I'll probably bring it back to my original point, right? That by design, we have built a more durable source of revenue where we are not dependent on one region or one vertical or one product to achieve our goals, right? This is helping us also be much more balanced.
Okay. Thank you. Brian, I would like to ask questions about gross margin. The first question is, like the non-GAAP service gross margin has been running at 85%-86% in the first half, significantly above historical level. How sustainable is it at mid-80%? The second part is, during analyst day, you said the midterm 2020-2023 gross margin target is 78%-80%. First half of 2022 gross margin is 80% at the high end. Is there any scenario that may bring 2022 gross margin closer to the low end of 78%? Or should we think that 80% is well-positioned to be in the upper end of that, like 78%-80% target, midterm target?
Yeah. No, you're exactly right. We had guided 78%-80% for this year on a full year basis for gross margin. We still think that that's the right range. We're obviously tracking towards the higher end of it. I would say that's probably the right way to look at it. Like you said, out years, we're targeting 80%-82%. You know, we're tracking pretty well, managing through what we can given the environment.
Yeah. I think, Hendi , just one thing to add to that, right, is of course what we don't know as a headwind is cost pressures, whether it's on shipping and logistics or chip supply or whatever. What we do know is we are also driving a lot of productivity measures that has helped us offset those, right, which is what has helped us keep it at 80%, so.
Okay. Yep. Thank you, Dhrupad. Thank you, Brian. Congratulations on strong results.
Thanks very much.
Thanks, Hendi.
Thank you. There are no further questions in the queue, so I will now pass it back to Dhrupad Trivedi for closing remarks.
Thank you. First of all, I want to thank all the global employees of A10 for a great quarter and continuing to build a strong technical and commercial foundation for the future. Thanks to all of our shareholders for joining us today and for your continued support. Thank you.
This concludes the second quarter 2022 earnings conference call. Thank you for your participation. You may now disconnect your line.
