• Stock reaction catalysts: continued AI/graphics card momentum (record expected in Q4), BOM content gains with multiphase controllers/power stages, and tariff-related PC pull-ins; watch for margin trajectory, licensing wind-down, and smartphone demand mix.

What Went Well and What Went Wrong

What Went Well

• “Our fiscal Q3 results were at the high-end of our guidance, supported by strength in Computing and better-than-expected demand in tablets.” — CEO Stephen Chang.
• Computing segment grew nearly 15% y/y and 3.6% q/q, aided by tablet strength and notebook pull-ins amid tariff uncertainty; graphics/AI accelerator demand remained robust with a key customer scaling next-gen platform.
• Design win secured in a data center application with notable BOM content increase; volume production began in March quarter and continues into June, underpinning total solutions strategy (controller + multiple power stages).

What Went Wrong

• Gross margin compression: GAAP GM fell to 21.4% (from 23.1% q/q; 23.7% y/y) and non-GAAP GM to 22.5% (from 24.2% q/q; 25.2% y/y), mainly from the wind-down of licensing/engineering revenue.
• Communications saw a seasonal 14.4% q/q decline (Tier-1 U.S. smartphone) and China expected slower sales into June; visibility in H2 2025 remains limited due to macro/trade uncertainties.
• Non-GAAP operating swung to a loss (-$2.7M vs +$3.0M q/q) and non-GAAP EPS to -$0.10 vs +$0.09 q/q; operating cash flow fell to $7.4M with customer deposit repayments of $9.6M.

Good afternoon, everyone, and welcome to Alpha and Omega Semiconductor's conference call to discuss Fiscal 2025 third-quarter financial results for the quarter ended March 31, 2025. I'm Steven Pelayo, Investor Relations Representative for AOS. With me today are Steven Chang, our CEO, and Yifan Liang, our CFO. This call is being recorded and broadcast live over the web. A replay will be available for seven days following the call via the link in the Investor Relations section of our website. Our call will proceed as follows today: Steven will begin business updates, including strategic highlights and a detailed segment report. After that, Yifan will review the financial results and provide guidance for the June quarter. Finally, we will have a Q&A session. The earnings release was distributed over the wire today, May 7, 2025, after the market closed. The release is also posted on the company's website.

Our earnings release and this presentation include non-GAAP financial measures. We use non-GAAP measures because we believe they provide useful information about our operating performance that should be considered by investors in conjunction with the GAAP measures. A reconciliation of these non-GAAP measures to comparable GAAP measures is included in the earnings release. We remind you that during this conference call, we will make certain forward-looking statements, including discussions of the business outlook and financial projections. These forward-looking statements are based on management's current expectations and involve risks and uncertainties that could cause our actual results to differ materially. For a more detailed description of these risks and uncertainties, please refer to our recent and subsequent filings with the SEC. We assume no obligation to update the information provided in today's call. Now, I'll turn the call over to our CEO, Steven Chang. Steven?

Stephen Chang (President and CEO)

Thank you, Steven. Welcome to Alpha and Omega's Fiscal Q3 earnings call. I will begin with a high-level overview of our results and then jump into segment details. We delivered Fiscal Q3 revenue and EPS results at the high end of our guidance, driven by better-than-expected demand in computing. Revenue was $164.6 million. Non-GAAP gross margin was 22.5%. Non-GAAP EPS was a loss of $0.10. Total revenue increased 9.7% year-over-year and declined 4.9% sequentially. As previously noted, licensing revenue began to wind down in the March quarter. Excluding licensing, our product revenue was up 11.6% year-over-year and down 3.5% sequentially. We saw seasonal sequential declines in Fiscal Q3 from each of our major segments, except the computing segment, which grew slightly sequentially against seasonality, driven by tablets and notebooks. The computing segment increased nearly 15% year-over-year. Looking ahead, we face a dynamic landscape with macroeconomic, geopolitical, and trade-related uncertainties.

Currently, our direct tariff exposure is minimal due to limited U.S. shipments, but we're closely supporting customers navigating supply chain complexities to ensure compliance and minimize disruptions. While we're seeing a near-term uplift in the first half of the calendar year, broader visibility for the second half of 2025 remains uncertain. Nonetheless, we are delivering on our commitments and advancing our transformation from a component supplier to a total solutions provider. Our goal is to leverage premier customer relationships to expand market share and increase bond content with a broader portfolio. With that, let me now cover our segment results and provide some guidance by segment for the next quarter, starting with computing. March quarter revenue was up 14.8% year-over-year and up 3.6% sequentially, and we represented 47.9% of total revenue. These results were ahead of our original expectations for a slight decline.

The upside was driven by better-than-expected tablet demand, with revenue nearly doubling year-over-year to a quarterly record due to market share gains, as well as some demand pulled in from notebooks due to tariff uncertainties. In the March quarter, we continue to experience robust demand for graphics and AI-accelerated cards, driven by a key customer scaling their next-generation platform. Looking ahead to June, we anticipate even stronger performance with graphics card revenue projected to reach a record high. For AI applications, demand for high-performance compute remains robust, and we are encouraged by the continued strong growth in data center capital spending. In Q1, we broadened our penetration with an existing premier customer to secure a design win in one data center application with a notable increase in bond content. This is a testament to our ability to provide total solutions with multi-phase controllers and multiple power stages per GPU.

Volume production for this program started in the March quarter and will continue into the June quarter. Design inactivity is still ongoing for additional programs. However, visibility for the second half of the year remains limited due to uncertainties in end market demand. In the PC market, we expect continued pull-in activity through the June quarter, driven by fluid trade regulations. In summary, we expect the computing segment to increase mid-single digits in the June quarter and more than 15% year-over-year. The sequential growth is driven by PC-related pull-ins and strength in graphics cards. However, it is important to note that visibility into the second half of the year remains limited due to uncertain macro environment and evolving trade policies. Turning to the consumer segment, March quarter revenue was down 9% year-over-year and down 4.9% sequentially and represented 13% of total revenue.

The results were in line with our forecast, driven by seasonality in gaming and home appliances, as well as a pullback in wearables following a record level achieved in the third calendar quarter of 2024. For the June quarter, we forecast more than 25% sequential growth in the consumer segment, driven by gaming and home appliances. Gaming is expected to be particularly strong due to pull-ins for a targeted marketing push from a key customer. Next, let's discuss the communication segment. Revenue in the March quarter was up 5.8% year-over-year, down 14.4% sequentially, and represented 17.2% of total revenue. The results were in line with our expectations for a seasonal sequential decline from our tier-one U.S. smartphone customer, while China OEMs moderated only slightly, and Korea was sluggish as customers prepared for product launches in the first calendar quarter.

We believe communications results continue to reflect a combination of market share gains, a mix shift to higher-end phones in China, and generally higher charging currents, driving increased BOM content. Looking ahead, we anticipate sluggish sequential growth in the June quarter for the communication segment. By region, we expect growth from smartphone customers in the U.S. and Korea, offset by slower sales from China. Now, let's talk about our last segment, power supply and industrial, which accounted for 19.9% of total revenue and was up 32.4% year-over-year and down 6.2% sequentially. The results were ahead of our forecast for a low-teens sequential decline, primarily driven by a seasonal decline in quick chargers, offset by sequential growth in e-mobility and AC/DC power supplies. As we stated before, we see additional opportunities in 2025 for quick chargers due to increased BOM content driven by higher charging currents.

Further, we are leveraging relationships in Taiwan to partner on DC fans for server racks. For the June quarter, we expect revenue to be flat to slightly down sequentially for the power supply and industrial segment, primarily driven by a seasonal increase in quick chargers and AC/DC power supplies, offset by lower e-mobility revenue. In closing, we are pleased that March quarter results were better than expected, ahead of seasonality primarily due to pull-ins in the computing segment. Looking ahead, we face a dynamic geopolitical and macroeconomic environment. We are monitoring developments, ensuring compliance, diversifying our supply chain, and collaborating with customers to minimize disruptions. For the June quarter, driven by strength in computing and consumer segments, we currently expect low to mid-single digit sequential revenue growth, suggesting June quarter revenue should approximate the levels achieved in the December quarter, despite the stronger March results and discontinuation of licensing revenue.

Excluding the impact from discontinued licensing revenue, we expect mid to upper single-digit revenue growth. Gross margins in June should also approach a level achieved in the December quarter, driven by improved utilization rates and a richer product mix. Our business fundamentals remain strong, supported by cutting-edge technology, a diverse product portfolio, and marquee customer base. We expect revenue growth in calendar 2025, driven by new market expansion, market share gains, and increased bond content. While near-term uncertainties remain, our focus remains steadfast on executing our strategy and delivering sustained value for our stakeholders. With that, I will now turn the call over to Yifan for a discussion of our Fiscal third-quarter financial results and our outlook for the next quarter. Yifan?

Yifan Liang (CFO and Secretary)

Thank you, Steven. Good afternoon, everyone, and thank you for joining us. Revenue for the quarter was $164.6 million, down 4.9% sequentially and up 9.7% year-over-year. In terms of product mix, DMOs revenue was $106.8 million, down 5.4% sequentially and up 13.9% over last year. Power AC revenue was $54.6 million, up 1.6% from the prior quarter and 9.2% from a year ago. Assembly service and other revenue was $0.4 million as compared to $1.1 million last quarter and $1.2 million for the same quarter last year. License and engineering service revenue was $2.8 million for the quarter versus $5.4 million in the prior quarter and $5.1 million for the same quarter a year ago. This license and engineering service contract was completed in mid-February. Non-GAAP gross margin was 22.5% compared to 24.2% last quarter and 25.2% a year ago.

The quarter-over-quarter decrease was mainly impacted by lower license and engineering service revenue in the March quarter. Non-GAAP operating expenses were $39.7 million compared to $39 million for the prior quarter and $38.9 million last year. The slight quarter increase was primarily due to higher payroll tax expenses given the start of a new calendar year. Non-GAAP quarterly EPS was negative $0.10 compared to $0.09 per share last quarter and a negative $0.04 per share a year ago. Moving on to cash flow. Operating cash flow was $7.4 million, including $9.6 million of repayment of customer deposits. By comparison, operating cash flow was $14.1 million in the prior quarter and $28.2 million last year. We expect to refund $2.7 million customer deposits in the June quarter. We also repurchased 306,000 shares of employee-restricted stock units vested during the quarter for $9.4 million.

EBITDAS for the quarter was $11.2 million compared to $16.8 million last quarter and $11.6 million for the same quarter a year ago. Now, let me turn to our balance sheet. We completed the March quarter with a cash balance of $169.4 million compared to $182.6 million at the end of last quarter. Net trade receivables increased by $8.6 million sequentially. Day sales outstanding were 11 days for the quarter compared to 12 days for the prior quarter. Net inventory increased by $4.4 million quarter over quarter. Average days in inventory remained at 129 days for the quarter. CapEx for the quarter was $8.1 million compared to $7.4 million for the prior quarter. We expect CapEx for the June quarter to range from $12 million to $14 million. Now, I would like to discuss June quarter guidance. We expect revenue to be approximately $170 million plus or minus $10 million.

GAAP gross margin to be 22.9% plus or minus 1%. We anticipate the non-GAAP gross margin to be 24% plus or minus 1%. GAAP operating expenses to be $47.1 million plus or minus $1 million. Non-GAAP operating expenses are expected to be $40.2 million plus or minus $1 million. Interest expense to be approximately equal to interest income and income tax expense to be in the range of $0.9 million-$1.1 million. With that, we'll open the call for questions. Operator, please start the Q&A session.

Great. If you would like to queue for a question, you can do so by pressing Star 1 on your telephone keypad. If for any reason you'd like to remove your question, it's Star 2. Again, to join the question queue, please press Star 1. Our first question is from David Williams with Benchmark. Your line is now open.

David Williams (Equity Research Analyst)

Hey, good afternoon. Thanks for taking my question and certainly congrats on the good quarter here. I guess maybe, Steven, I missed a little bit of the beginning of the call there, but I wanted to see if you could help kind of quantify the magnitude of the pull-ins that you discussed on the PC side and maybe also talk about any of the graphics cards success that you've had this quarter and how you're kind of thinking about that going forward. Thanks.

Stephen Chang (President and CEO)

Sure. For the first part of the question about the pull-ins, certainly we did see some increased demand because our customers are trying to take advantage of the current situation of the tariffs. This is more pronounced, especially in the computing segments, particularly with our notebook shipments. Normally, the March quarter is a down season, and this was muted somewhat because of the tariff and the pull-ins from some of our PC customers. To quantify that, I think we beat the midpoint by about $6 million. Maybe half of that could come from the notebook increase. We also can expect to see that going into the June quarter as well. Regarding our graphics business, we are excited to be taking part in selling into the new versions of both graphics cards as well as the AI accelerator cards.

We already started shipping at the end of last year, and we continue to ship at the beginning of this year and going throughout this year. In this portion, I think we are encouraged by what we see, and our customers are pulling product. They are getting GPU allocation, and they are shipping out. We are glad to take a part of that.

David Williams (Equity Research Analyst)

Great. Certainly great to hear there. Maybe secondly, can you kind of help us kind of understand the tariff impact to you all? Just kind of given where your manufacturing is and your presence there, how much of your product or sales do you think come back into the U.S.? Maybe is there any way to kind of size that tariff impact overall from outside of what the demand could be, but just your direct impact?

Yifan Liang (CFO and Secretary)

Okay, sure. Obviously, this is a very dynamic and challenging and evolving issue for us, also for the semiconductor industry and for the overall macro economy. Tariffs definitely created a lot of unknowns. There are direct impact and indirect impact. Our direct exposure to tariffs so far is only very limited, as our shipments into the U.S. are minimal. Indirect impact on the overall demand for end products and devices remains to be seen. It's not that clear at this point. We are monitoring the situation, ensuring full compliance in multiple countries and areas so that we can make adjustments quickly in response to regulatory developments. We are also working closely with our customers to minimize any disruptions so that we can meet their supply requirements.

David Williams (Equity Research Analyst)

Great. Just one last one for me, if possible. I know that next quarter, you talked about the licensing revenue and that engineering service is falling off. I know that was expected to be kind of a margin impact, but you're guiding margin up here sequentially. Is that just a function of the higher revenue base, or what is it that's helping you lift that margin? How sticky and sustainable is that? Should we expect the margin to incrementally improve as we see that top line grow as well? Thank you.

Yifan Liang (CFO and Secretary)

Sure. For the June quarter margin guidance, we factored in better product mix, and so far we saw, and also we expect a higher utilization at our factories. Both factors contributed to the margin rebound.

David Williams (Equity Research Analyst)

Thank you.

We have a question from Jeremy Quan with Stifel. Your line is now open.

Jeremy Quan (Analyst)

Yes. Good afternoon and congrats on a very solid quarter and outlook, especially in this environment. Maybe a quick follow-up on the tariff question. Just looking at your China JV, is it fair to say that the vast majority of that production is for use within China or even all of it? Can you remind us again how much the JV, what percent of your wafer requirements is sourced out of your China JV?

Yifan Liang (CFO and Secretary)

Sure. Yeah. JV is right now just accounted for about 20% also of our total supply. Right now, under the current regulations and policies, their impact from tariffs is kind of minimal to us.

Jeremy Quan (Analyst)

Got it. And just following up on the utilization question, can you remind us where you are currently and both internally within your Oregon fab and also at the JV?

Yifan Liang (CFO and Secretary)

JV, we do not count them as our internal capacity. We treated them as one of our suppliers. For us, internally, overall utilization is around 80%-90% range, so on an overall basis. We still have additional external capacities to support our business.

Jeremy Quan (Analyst)

Can you comment further on that? Have you developed additional foundry partners? What kind of additional capacity is available to you at the JV?

Yifan Liang (CFO and Secretary)

Sure. Yeah. We have been developing third-party foundries, and during the last few years, yeah, we'll continue to do that. Yeah. That would add capacity even to support our next year's expected growth. We are mapping out those capacity requirements right now. In terms of JV, yeah, they still have additional capacity if we need it to support us.

Jeremy Quan (Analyst)

Great. A question on the first, congrats on the very solid cash flow. Looks like it was about $17 million if you exclude the customer deposit repayments. Can you talk about what kind of cash flow dynamics you expect as we move throughout the year? Also on the CapEx side, I know you mentioned, I think it was $12 million-$14 million next quarter. Can you just give us a sense of where that might land for the full calendar year 2025? Thank you.

Yifan Liang (CFO and Secretary)

Sure. Overall cash flow, I would expect that, yeah, it's kind of stable for us at this point. Overall, next quarter, we expect to pay only $2 million or $3 million on customer deposits. And then for the whole year, we still have about $16 million to go for the June quarter, September quarter, and December quarter. In terms of overall, I mean, right now, we don't see a whole lot of issues with CapEx. So we're generally targeting 6%-8% of our revenue. This year could be around $40 million-$50 million each. This CapEx, I mean, from quarter to quarter could fluctuate. Last two or three quarters, we were running around $7 million or $8 million. Next quarter, we expect like $12 million-$14 million also. By and large, we're still within our overall target.

Jeremy Quan (Analyst)

Got it. Maybe one last question before I jump back into you later. Can you give us an update on the pricing environment and maybe a quick update also on the competitive landscape? I know in the past, you've talked about local suppliers kind of increasingly at the low end. Any kind of detail you can provide would be great. Especially pricing as it relates to, yeah, just where you see things going over the next maybe 6 to 12 months. Thank you.

Yifan Liang (CFO and Secretary)

Okay, sure. ASP erosion on the same product basis for the March quarter was tracking toward historical trend line. Overall, we saw increased competition from all players, I mean, big or small. Overall, what we want to do is to roll out our new products to provide better performance and more functionalities to reset the ASP. That's the name of the game. We'll continue to do that.

Jeremy Quan (Analyst)

Got it. Thank you very much.

Yifan Liang (CFO and Secretary)

Thank you.

Stephen Chang (President and CEO)

Thanks.

Moderator (participant)

If there are any additional questions, please press star one on your telephone keypad. We have a follow-up from Jeremy Quan. Your line is now open.

Jeremy Quan (Analyst)

Thank you. I guess I could stay down. Maybe a follow-up on the AI accelerator cards. It sounds like that's going to be a pretty nice opportunity for you guys, and there could be potential to expand into other opportunities. Can you just give us a little bit more color into whether these are—do you have any visibility to whether these are associated with any specific hyperscalers or AI providers in particular? Also, yeah, what kind of new opportunities are you looking at? Is it more accelerated cards, or is it different kind of, I guess, architectural designs that you can talk about? Thank you.

Stephen Chang (President and CEO)

Sure. The near-term growth that we see has been in the AI-accelerated cards. Just to remind, again, we're selling a total solution here, including a multi-phase controller along with a power stage and actually quite a number of power stages per GPU. There is a wider range of graphics/AI-accelerated cards, from low-end cost-effective ones to high-performance cards. We are servicing the whole array of that. I do not know exactly where it is going into in terms of the end customer, but I can say that our products are shipping into various performance products for our direct customer. We do expect that is going to continue to grow. I think the ramp-up is still continuing to happen. We are guiding that it will grow further going into the June quarter and hopefully more after that as well. It does not stop there.

Our initial growth for this year will be coming from the graphics side, but we're also working on getting into the data center side. In this earnings release, we did mention that we did achieve a design win on one data center application. This is something that we already started shipping in this second quarter, sorry, in this June quarter. We are hoping to also get onto more programs beyond that. That portion, I think, is just starting, and we're hoping to be able to expand into more programs after that.

Got it. Is this for both the onboard power as well as the, I guess, what is it called, the backplane power, the 48 volts or the higher voltage power coming in the data center?

Right now, it's mainly still the low voltage solutions directly powering the GPU. We're talking about, again, the multi-phase controller coupled with multiple power stages.

Jeremy Quan (Analyst)

Got it. That goes for your data center side as well that you mentioned.

Stephen Chang (President and CEO)

Yeah. Except that that counts for the power stages go up even higher because of the higher performance.

Jeremy Quan (Analyst)

Got it. Great. Thank you very much.

Stephen Chang (President and CEO)

Thank you.

Moderator (participant)

There are no additional questions at this time, so I'll pass it back to the team for any closing remarks.

Steven Pelayo (Managing Director and Head of Investor Relations)
