Good afternoon, and thank you for attending the Alpha and Omega Semiconductor Fiscal Q4 2025 Earnings Call. My name is Shawn, and I'll be the moderator today. [Operator Instructions] I'd now like to pass the conference over to your host, Stephen Pelayo.

Good afternoon, everyone, and welcome to Alpha and Omega Semiconductor's conference call to discuss fiscal 2025 fourth quarter. I am Stephen Pelayo, Investor Relations representative for AOS. With me today are Stephen 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 7 days following the call via the link in the Investor Relations section of our website. Our call will proceed as follows today. Stephen 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 September quarter. Finally, we will have a Q&A session. The earnings release was distributed over the Wire today, August 6, 2025, after the market close. 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, Stephen Chang. Stephen?

Thank you, Steven. Welcome to Alpha and Omega's Fiscal Q4 Earnings Call. I will begin with a high-level overview of our results and then jump into segment details. We delivered fiscal Q4 revenue results at the high end of our guidance due to better-than-expected demand in computing, mostly driven by tariff-related customer pull-ins for PCs and strong sequential growth in AI and graphics chips. Our Consumer segment also saw strong sequential growth related to wearables and gaming. Overall, total June quarter revenue was $176.5 million, non-GAAP gross margin was 24.4%, non-GAAP EPS was $0.02. Total revenue increased 9.4% year-over-year and 7.2% sequentially. As previously noted, licensing revenue wound down in the March quarter. Excluding licensing and other revenue, our product revenue was up 13.7% year-over-year and 9% sequentially. Power IC revenue increased 25.8% sequentially and 30.2% year-over-year to a record quarterly high and now represents nearly 40% of total product revenue. The richer mix of power IC benefits gross margins and comes from graphics, AI, gaming and PC markets. On July 14, we announced an equity transfer agreement with a strategic investor to sell approximately 20.3% of outstanding equity interest of AOS' joint venture in Chongqing, China for an aggregate cash consideration of $150 million. The sale is expected to provide AOS with significant additional capital to continue investing in technology, equipment and acquisition of assets complementary to our business operations to support key growth areas. In summary, uncertainties regarding macro economy and geopolitics continue. 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 BOM content with a broader portfolio. With that, let me now cover our segment results and provide some guidance by segment…

Thank you, Stephen. Good afternoon, everyone, and thank you for joining us. Revenue for the June quarter was $176.5 million, up 7.2% sequentially and up 9.4% year-over-year. In terms of product mix, DMOS revenue was $107.3 million, up 0.4% sequentially and 5.1% over last year. Power IC revenue was $68.7 million, up 25.8% from the prior quarter and 30.2% from a year ago. Assembly service and other revenue was $0.5 million as compared to $0.4 million last quarter and $1.4 million for the same quarter last year. We did not have any license and engineering services revenue this quarter as the related contract was completed in mid-February. This compares to $2.8 million in the prior quarter and $5.1 million in the same quarter last year. Non-GAAP gross margin was 24.4% compared to 22.5% last quarter and 26.4% a year ago. The quarter-over-quarter increase was primarily impacted by the mix improvement. Non-GAAP operating expenses were $40.9 million compared to $39.7 million for the prior quarter and $39.3 million last year. The quarter-over-quarter increase was primarily due to higher R&D engineering expenses. Non-GAAP quarterly EPS was $0.02 compared to negative $0.10 per share last quarter and $0.09 per share a year ago. Moving on to cash flow. Operating cash flow was negative $2.8 million, including $2.7 million of repayment of customer deposits. By comparison, operating cash flow was $7.4 million in the prior quarter and $7.1 million last year. We expect to refund $5 million of customer deposits in the September quarter. EBITDAS, excluding impairment of equity investment for the quarter was $10.5 million compared to $15.2 million last quarter and $16 million for the same quarter a year ago. Now let me turn to our balance sheet. We completed the June quarter with a cash balance of $153.1 million compared to…

[Operator Instructions] Our first question is from David Williams with Benchmark. Our next question is from Jeremy Kwan with Stifel.

Maybe if you could provide a little bit more color on the computing segment. It looks like that was very nice to see and it was quite strong, especially on the AI and graphics. Can you help us understand the digestion that you mentioned? Is that related to the tariff pull-ins more generally? Or is that related to the strong initial shipments of the new AI program? And any color you can provide in terms of the AI contribution this quarter and how you see that going forward over the next couple of quarters would be very helpful.

Jeremy, so certainly, we're excited about our AI and graphics business. This is something that's been -- we've been building upon and expanding in our advanced computing area. And in terms of the digestion portion, this is a reflection of some of the -- one of the AI programs that we started shipping into in the last quarter, we shipped to it for a certain program, and we expect to take a little bit longer for that initial shipment to be digested. But at the same time, we're also -- and we commented in the call that we are excited that there are additional programs that we continue to be designed into that will help with that with that digestion. And at the same time, we already are seeing fresh orders as well forecast and backlog coming in for some of those new programs. So again, we are going after multiple types of projects here when it comes to AI. And this is in addition to what we're doing on the graphics side. On the graphics side, actually, we report also that is also fairly strong, and I would say, better than our original expectations with good share at the add-in card makers for the graphics cards. So we're excited about both of our AI as well as graphics business.

Great. That's very helpful. And can you help us quantify this maybe in qualitative terms, like how much your total AI is as a part of the consumer segment or maybe how much drove growth in the current quarter? And maybe how you see that shaping out over the next, maybe call it, 12 to 18 months?

Yes. We tend to look at both graphics and AI together when it comes to -- because the products are pretty similar when it comes to both the controller as well as the driver MOS that we're selling as a total solution. So those 2 together is somewhere in the neighborhood, maybe around 25% of computing these days.

Great. That's very helpful. And maybe if I can ask a question on the gross margin. I understand that the richer mix kind of helps with -- the richer mix of the Power IC helps with gross margins this quarter. It's kind of maybe flat next quarter, revenues are a little bit higher. Can we infer from that, that maybe the power IC mix shifts down a little bit here? Can you just help us understand kind of the dynamics near term and how you see this looking out, again, 12 to 18 months, especially as some of these newer, richer, higher-value products continue to ramp?

Sure, Jeremy. Yes, in the June quarter, our gross margin improved quarter-over-quarter pretty nicely. So it was back up to the December 2024 quarter level. So primarily because of the better mix. Keep in mind, in the June quarter, we did not have any license and engineering service revenue compared to the March quarter because that contract, 24-month contract expired in mid-February. So this -- in terms of September quarter guidance, flat compared to the June quarter on the gross margin -- basically reflected similar mix -- product mix and similar production level. And I mean, that's revenue, yes, there was a little bit higher compared to the June quarter. So we still have revenue inventory and also other inventory we purchased from third-party foundries and subcontractors to support. So overall, we see -- at this point, we see a flattish gross margin in the September quarter.

And beyond the September quarter, how should we think about gross margins, especially do we -- are you expecting the mix to continue increasing or to be more increasingly favorable? Just any kind of color you can provide on that would be helpful.

Sure. I mean we don't give longer-term guidance. I mean, we only guide one quarter at a time. But overall, yes, I mean, as our revenue continue to grow, then I would expect -- in the growth area, I would expect we can -- we expect to see a better product mix.

Got it. And one last question, if I could. Just thinking about the sale or the transfer of a portion of your JV holdings, that $150 million, can you maybe rank order your priorities in terms of how you're thinking about CapEx, OpEx, maybe some M&A. Is there any thought as to shareholder returns? Yes, just any kind of indication about how you think about that cash inflow?

Sure. First of all, I mean, this $150 million cash deal, we expect to be completed in the next few months, I mean, probably by the end of this calendar year. And then the first payment, we can expect probably in the September quarter and then rest of the money expected to come in, in the December quarter. In terms of use of cash, I mean, we definitely will invest in our business growth, and we do see quite a bit of growth opportunities ahead of us. So yes, we'll invest in our technology, across our talents and then expanding our capacity. I mean M&A is also on the plan, but that one depends on the opportunity. yes, I'm sure our Board will evaluate in terms of return capital to investors. So that's all how that's like.

Our next question is from David Williams with Benchmark.

I apologize for the first issue there. Look, kind of following up on the last question on the JV. If you kind of think about your balance sheet now, it feels like -- and you talked about your utilization in third-party foundries, and that's provided some nice flexibility in the past. But I wonder how you think about adding or bringing in additional capacity internal to help you drive the margin profile as you kind of scale the business. Is that a place you want to be? Or would you prefer to have this kind of even split between third-party and internal and the JV?

Sure. I mean this definitely -- I mean, this $150 million transaction definitely will bring in more capital to us and also increase some flexibility in terms of where we want to set up our supply. Yes, we'll continue to evaluate both internal production and purchasing from third-party foundries. It depends on our needs, sure. I mean after this transaction, I mean, our balance sheet definitely got strengthened that we would have quite a bit liquidity and also -- I mean, we created quite a bit of value for our investors. I mean that's -- if you look at this deal and then in the past, we recorded $300 million on our balance sheet in this equity investment. Throughout the years, including this deal, we already realized about $176 million or cash. And then we still own 18.9% even after this transaction. So I mean, I would say, yes, this deal definitely created a heck of value for our investors.

Yes. No doubt. If my memory is certainly correct, you were $30 million to $35 million total, including equipment and some cash. Is that right?

We invested $35 million cash plus some used assembly equipment.

Yes, that is a heck of a return. So congrats on that. And I guess maybe as you think about your internal capacity and tariffs and then shipping, just kind of given how much of your customer base ends up in Asia, how do you think the tariffs are impacting your local manufacturing capacity? Is that. Is it a bigger challenge for you than maybe being outside of the country and moving outside largely? And just maybe what's your exposure do you think to the tariffs on that side of the house?

So far, I mean, the direct impact from tariff on us is not that significant since we don't ship a whole lot of products to the U.S. So from that front, yes, right now, we're okay, but this geopolitical and trade tension do play some uncertainties here. So we'll adjust our supply chain along with our customers. And so basically, we want to support our customers. So wherever our customers are located, and we want to support them.

Great. And maybe, Stephen, how do you -- or maybe if you think about how your customers have been reacting, do you sense that there's more cautiousness out there in terms of the demand side and kind of where things lead? Or do you feel like people are generally feeling better about the second half from the underlying demand side?

I think the answer is different depending on which market you're looking at. In terms of the tariff impact, we see that on the demand side more prominently in the computing side when it comes to notebooks and desktops over there, and we are still dealing with how to support the pull-in efforts and with demand being pulled in by our customers in advance of any kind of policy change when it comes to tariffs. So as of right now, our customers are still wanting to produce as much as they can and get things into -- get things get produced and onto a boat before the tariffs change. So that's more and more prominently so in the PC market. We don't really see the tariff impact in other areas. Others are more other impacts. Of course, anything with AI is definitely still very hot. graphics still continues to be strong as well, too, since that the cards -- graphics cards just launched at the beginning of this year. The AI programs are just starting up also. So those are still fresh new projects. Smartphones, we're heading into the peak season with the U.S. and the Korea smartphone maker also going into peak production. So those are seasonal effects that we're seeing now.

It looks like there are no more questions. So I'll pass the call back over to the management team for closing remarks.

Great. Before we conclude, I'd like to highlight a few upcoming investor events. The management team will be participating in the Sixth Annual Needham Virtual Semiconductor and SemiCap One-on-One Conference on August 21, the 2025 Evercore Semiconductor IT Hardware and Networking Conference on August 26; and the Jefferies Semiconductor IT Hardware and Communications Technology Conference on August 27. Both of those are in Chicago, Illinois, as well as the Benchmark 2025 Tech, Media and Telecom Conference on September 3 and TD Securities Technology Growth Cap Summit on September 4. Both of those are in New York City. If you wish to request a meeting, please contact the institutional sales representative at each sponsoring bank. This concludes our earnings call today. Thank you for your interest in AOS, and we look forward to talking to you again next quarter.

Thank you.

Thank you.

That concludes the conference call. Thank you for your participation. Enjoy the rest of your day.
