Speaker 2

Thank you, Steve. 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 results in line with our guidance for revenue and gross margin. Revenue was $161,300,000 non GAAP gross margin was 26.4 percent non GAAP EPS was $0.09 As we mentioned last quarter, inventory corrections across the majority of our end markets are now largely behind us and seasonality is returning to more normalized trends.

Speaker 2

While visibility on the slope of the recovery is limited, the increasing breadth of demand is encouraging. For the June quarter, we saw sequential growth in each of our major segments with relative strength coming from tablets, AI, graphics cards in our Computing segment, gaming and home appliances within consumer, e mobility, DC motors and quick chargers in the industrial segment and a regional shift towards a Tier 1 U. S. Smartphone customer within communications. The PC segment however is taking longer to recover than originally expected.

Speaker 2

Looking into the September quarter, we expect PCs and servers to grow sequentially while tablets sustain the strong current run rate within computing. The consumer segment will likely see continued strength in gaming and a strong seasonal pickup from wearables offset by slower home appliances. Smartphones will drive sequential growth in communication, while ACDC power supplies and quick chargers are relatively stronger in industrial. Looking beyond 2024, AOS is transitioning from a component supplier to a total solutions provider in many areas where we can leverage our core strength in high performance silicon, advanced packaging and intelligent ICs to penetrate new opportunities and drive higher BOM content. We are building on customer relationships to capture market share with a broader product portfolio.

Speaker 2

For example, we are leveraging our strength in graphic cards and introducing new Vcore products for opportunities in advanced computing and AI data centers. Within smartphones, we expect to benefit from trends towards foldable, flexible and multiple screens, increasing AI integration as well as dual cell batteries and higher charging currents for faster charging times. Beyond Computing and Communications segments, we remain optimistic on the underlying power trends in adjacent markets such as solar, motors and e mobility, gaming, home appliances and power tools. These examples all represent continued growth opportunities primarily driven by the global shift towards more efficient and sustainable energy solutions. With that, let me now cover our segment results and provide some guidance by segment for the next quarter.

Speaker 2

Starting with Computing. June quarter revenue was up 37.6% year over year and 4.4% sequentially and represented 44.4 percent of total revenue. These results were slightly below our original expectation for mid to upper single digit growth. As mentioned before, we saw relative strength from tablets, AI and graphics cards in the quarter, offset by a slower PC market recovery. Notably, tablet revenue was a record high and the contribution from AI and data center related applications continued to grow.

Speaker 2

We are excited about opportunities in AI. Demand for accelerator cards remains steady as the industry prepares for a platform transition ramping year. We are working on multiple opportunities, leveraging our existing relationship with a key graphics card maker as well as our product portfolio including new multi phase V Core controllers and a power stage solutions for advanced computing. We're also seeing some ramp in September from a leading power supply maker that is a key supplier to the same AI graphics customer. We are selling our high performance medium voltage MOSFETs that go into intermediate bus converters for DC to DC power conversion.

Speaker 2

Looking forward into the September quarter, we expect the Computing segment to grow mid single digits sequentially as PCs see a seasonal pickup, while tablets, AI accelerators and graphics cards remain strong. Turning to the Consumer segments. June quarter revenue was down 35.5% year over year, but up 19.7% sequentially and represented 17.5 percent of total revenue. The results were in line with our forecast for double digit sequential growth and were primarily driven by gaming and home appliances. It is now clear that the inventory correction in gaming is behind us and a seasonal build is underway.

Speaker 2

The strength in home appliances was better than expected as government incentives in China drove demand. For the September quarter, we forecast low double digit sequential growth in the consumer segment driven by strong seasonal pickup from wearables and continued strength in gaming offset by slower home appliances. Next, let's discuss the Communications segment. Revenue in the June quarter was up 59% year over year and 2.1% sequentially and represented 17% of total revenue. These results were above our flattish sequential expectations as we began to see the seasonal pickup from a Tier 1 U.

Speaker 2

S. Smartphone customer, offset by sequential declines from Korea and China OEMs. Looking ahead, we anticipate double digit sequential growth in the September quarter on seasonal strength ahead of new smartphone launches in the U. S. And increasing demand from China smartphone OEMs.

Speaker 2

We are benefiting from a mix shift to more premium phones and we anticipate rising growth in BOM content as phone makers increase battery charging currents. Now let's talk about our last segment, Power Supply and Industrial, which accounted for 17.1% of total revenue and was down 33.7% year over year, but up 11.3% sequentially. The results were slightly ahead of our forecast for mid to upper single digit sequential growth, driven by strength in the e mobility segment for e bikes and e scooters and DC fans for applications in areas such as data centers. The inventory correction in quick charger appears complete as we also saw the beginnings of recovery in the June quarter. Lastly, Power Tools continued at a steady pace in June.

Speaker 2

For the September quarter, we expect this segment to grow 15% to 20% sequentially, primarily driven by a solid uptick from quick chargers as well as strength from ACDC power supplies tied to the seasonal build in PCs. In closing, the June quarter was in line with our expectations and marked a solid conclusion to our fiscal 2024 performance. The rolling inventory corrections we experienced over the past year in nearly every one of our end markets are now largely behind us and some markets like smartphones are starting to return, while new markets like AI are emerging. We expect seasonal growth in the September quarter, primarily driven by PCs, smartphones, wearables and gaming. Looking to the next cycle, we are poised for growth bolstered by advanced technology, a diversified product portfolio addressing a broadening array of end markets and a premier customer base across all product lines.

Speaker 2

Power management underpins key trends such as AI, digitalization, connectivity and electrification, especially as we move towards a sustainable low carbon society. We have steadfast in executing our technology roadmap. Customers increasingly view us as a total solutions provider allowing us to capture a greater portion of the bill of materials and ultimately supporting growth that outpaces industry over the long term. With that, I will now turn the call over to Yvonne for a discussion of our fiscal Q4 fiscal year financial results and our outlook for the next quarter.

Speaker 3

Thank you, Stephen. Good afternoon, everyone, and thank you for joining us. Revenue for the quarter was $161,300,000 up 7.5% sequentially and flat year over year. Seasonal demand was relatively broad based in the June quarter and confirmed the inventory correction is largely complete. In terms of product mix, Demos revenue was $102,100,000 up 8.8% sequentially and 6.7% over last year.

Speaker 3

ROIC revenue was $52,700,000 up 5.5% from the prior quarter and down 10.5 percent from a year ago. Assembly service and other revenue was $1,400,000 as compared to $1,200,000 last quarter and $600,000 for the same quarter last year. License and Engineering service revenue was $5,100,000 for the quarter versus $5,100,000 in the prior quarter and $6,300,000 for the same quarter a year ago. Non GAAP gross margin was 26.4% compared to 25.2% last quarter and 28.5% a year ago. The quarter over quarter increase was mainly driven by the improved factory utilization.

Speaker 3

Non GAAP operating expenses were $39,300,000 compared to $38,900,000 for the prior quarter and $39,100,000 last year. The slight quarter over quarter increase was primarily due to higher professional fees. Non GAAP quarterly EPS was $0.09 compared to $0.04 loss per share last quarter and $0.19 earnings per share a year ago. Moving on to cash flow. Operating cash flow was $7,100,000 including $4,500,000 of repayment of customer deposits.

Speaker 3

By comparison, operating cash flow was $28,200,000 in the Q4 and negative $28,200,000 last year. We expect to refund about $8,400,000 customer deposits in the September quarter. EBITDAS for the quarter was $16,000,000 compared to $11,600,000 in the last quarter and $17,700,000 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 $175,100,000 compared to 100 and $74,400,000 at the end of last quarter.

Speaker 3

Nitrate receivables decreased by $700,000 sequentially. Base sales outstanding were 12 days for the quarter compared to 15 days for the prior quarter. Net inventory decreased by $2,300,000 quarter over quarter. Average days in inventory were 148 days compared to 153 days in the last quarter. CapEx for the quarter was $7,200,000 compared to $7,400,000 for the prior quarter.

Speaker 3

We expect CapEx for the September quarter to range from $6,000,000 to $8,000,000 Now I would like to discuss September quarter guidance. We expect revenue to be approximately $180,000,000 plus or minus $10,000,000 GAAP gross margin to be 25 percent plus or minus 1%. We anticipate the non GAAP gross margin to be 26.4 percent plus or minus 1%. GAAP operating expenses to be in the range of $47,000,000 plus or minus $1,000,000 Non GAAP operating expenses are expected to be in the range of $40,000,000 plus or minus $1,000,000 interest expense to be approximately equal to interest income and income tax expense to be in the range of $900,000 to $1,100,000 With that, we will open the call for questions. Operator, please start the Q and A session.

Operator

We will now begin the Q and A session. The first question comes from the line of David Williams with Benchmark. Please proceed.

Speaker 4

Hey, good afternoon and congrats on the successfully navigating this volatile macro environment here. Certainly, you're doing a much better job and I think some of your peers have.

Speaker 2

With that, I guess, Stephen, I wanted to yes, I wanted to ask

Speaker 4

a little bit just on the graphics card and some of the data center accelerator and GPUs. You've talked about this before and starting to see those revenues. But I'm trying to understand what is it the magnitude of maybe that could be over time? And maybe is there a way to size, understanding there's different flavors or varieties of those products? But is there a good way to think about what your content can be?

Speaker 4

And maybe where you're at within that maybe qualification process today? Just any color around that would be incredibly helpful. Thank you.

Speaker 2

Sure. Yes. So our entry into artificial intelligence programs, a lot of it actually is built upon where we've already been with our graphics cards. And accelerate cards actually aren't that different from a graphics card in the sense that you're basically powering a high performance GPU in both cases. And but with data center, that performance is requirements are being driven even higher.

Speaker 2

So when we look at the content, actually the power solution isn't that different in that you have multiple power stages, usually driver MOSs that surround that GPU. The same thing happens with the celebrated cards, but in a bigger scale. So to quantify some of that, so for example, in a graphics card, you can have anywhere from 9 to 16, something in that range of number of driver MOSs per GPU. But when you move to an AI accelerated card, that number actually jumps up to even up to 50 power stages to power that GPU. And those are the solutions that we are shipping today in our graphics cardAI customer in their existing platforms.

Speaker 2

And we are working with them on being on transitioning over to the new platform that they will be launching soon. So we believe that for us, the AI accelerated card will be the portion that is that will grow earlier than other areas mainly because of our presence already in both in graphics cards as well as the AES Accelerator Card business that we enjoyed today.

Speaker 4

Perfect. Good color there. Thank you. And then maybe just can you talk a little bit about the multi phase controller? I know you've mentioned this last quarter, but it sounds like you're getting some nice adoption there, some good traction.

Speaker 4

Just how is that helping you out, I guess, across the breadth of your markets? What is the dollar opportunity there? And then maybe what are the benefits longer term as you introduce that multi phase controller?

Speaker 2

Sure. So our multi phase controller, we first released and deployed that for our client PC business. And you remember that we've been talking about with Intel's latest platforms that BOM content is increasing because of what they're doing with in bringing back more power rails. And our solution is actually a total solution. We offer both the multi phase controller, which is new for us in addition to the power stage.

Speaker 2

And that has helped us to expand the BOM content that we can address within a PC application. This is like a notebook or in a desktop type of application. And because we have that foundation, we're we've been we are working on and on transitioning that over to the next generation of graphics as well as AI accelerated cards. So the business I talked about before, in the past, we were only shipping driver MOSs. And in the future, we're expecting to ship and be able to ship both as a total solution.

Speaker 2

So it's important for us not only to expand the bond content within our current PC application, but it's also allowing us to step into the more advanced, you can say advanced computing high performance GPU area as well.

Speaker 4

And then maybe one last one for me for Yifan. As you kind of think about the gross margin, you're seeing a bit of an uplift here as we kind of move through the year, which is positive. But how do you think about the margin profile? And I'm sure I've asked you this almost every quarter. But just it seems like as that mix gets better, utilization comes back and then especially as you become a larger player in some of these, the GPU market or the accelerated market, it seems like there's some nice room for margin appreciation.

Speaker 4

Is that fair to say? And maybe how do you think about the margin trending through your FY 2025? Thank you.

Speaker 5

Sure. As you know, our September quarter's margin guidance, we guided flattish quarter over quarter. This is mainly because of we expected similar quarter over quarter factory utilization. We plan to consume some inventories and reduce inventory balance in the September quarter. So, other factors impacting the margin like product mix and ASP, Vision, we expect similar to the June quarter.

Speaker 5

So overall, we expect flattish margin quarter over quarter for the September quarter. So going forward, yes, I mean, I would expect and as we grow our revenue, then our product mix will continue to improve and then factory utilization will be higher. So those factors will be contributing to our margin improvement.

Speaker 4

Thank you. I'll get back in queue. I appreciate it.

Operator

Thank you. The next question comes from the line of Meyer Pour with B. Riley. Please proceed.

Speaker 6

Hi. Yeah. I'm actually calling in for Craig Ellis. And I was really just wanting to think about this AI data center ramp that's coming up in the second half. So you guys obviously have a lot of work in some very similar environments and can really pursue this, I think with a really great angle.

Speaker 6

So with all the different configurations and approaches to building these AI data centers, are you guys seeing different sign wins across the spectrum here with all the different ways that someone can approach these systems?

Speaker 2

Yes. And our customer our big customer has a lot of different end products. And they're catering it to folks building systems, they're catering to folks that want the total solution or they just want the accelerated car by itself. So for us, we actually have quite a good number of opportunities at play, but we believe that the updated accelerated card will come first for us. And because that's again, we have we already have track record there.

Speaker 2

We're already shipping in their older platforms. And going forward, I think both the graphics and the accelerated card is expected to share the same type of architecture. And we believe that for us in terms of the design win turning to revenue, that portion we will see first ahead of the other business. And at the same time, we are working on the other sockets that we're developing products for. We're being working on design wins for at the same time in parallel.

Speaker 6

Okay. Yes, that's great. Just to kind of follow-up on that, do you guys have any like quantification as far as kind of how many design wins you're on or how many sockets you've kind of tried to pursue design wins upon?

Speaker 2

We don't really quantify it that way. And but in general, we are seeing design wins and progress on the accelerator card. This is why we're talking about that more now because that's we believe is much more tangible and near term for us and it and lines up the best for us with our end customer. I do also want to mention that and in addition to this business that we're our business with this customer, We're also working with one of their suppliers that's producing and helping to supply into, I think we mentioned on the call, their intermediate bus converters. And we also have revenue even shipping today with our medium voltage MOSFETs.

Speaker 2

So powering this is the kind of the power stage before it gets to the point of load. And our customer is a big supplier to the AIcellular card the AIGraphics card maker. So we also expect to see that business continue to grow beyond this year into next year as the AI customer moves into their new platform.

Speaker 6

Okay. Yes, that's really great color. If I could just ask one last thing, kind of just thinking about how margins are going to change as your business kind of picks up into this new realm. Are we going to see normalization back to kind of like historic peaks around 30 ish? Or is this sort of the new normal now with 25% to 28% kind of extending forward?

Speaker 5

Yes. I mean, our overall midterm target model is still above 30% non GAAP gross margin with target revenue goal of $1,000,000,000 so that model will still stay. So we believe when we continue to grow and then incremental business, we expect to kind of bring in better product mix. So that would help us improve the gross margin gradually. Also, this incremental business would help us increase our utilization at factories.

Operator

The next question comes from the line of Jeremy Kwan with Stifel. Please proceed.

Speaker 6

Yes, good afternoon.

Speaker 7

Just wanted to there's a lot of interest obviously in the AI accelerator cards. Maybe a couple of questions here. First would be, can you clarify if this is consumer cards that are being adapted for enterprise or small data center applications? Or is this architecture designed from the ground up to be used in AI acceleration and data centers?

Speaker 2

Yes. Our business today is mostly the first in that. They use a similar solution for their graphics cards from their previous platform to address some of the AI needs today. But we're looking forward to what I'm talking about is that with the new platform that's coming out from this customer at the end of this year, beginning of next year, that platform is a grounds up kind of completely designed for AI. And that portion also addressing AI accelerated cards in that portion, this is what we're looking forward to seeing the transition for.

Speaker 7

Got it. And then with this, the new architecture platform, is the sockets. It sounds like there's maybe 3 opportunities here and please correct me if I'm wrong. But one would be the core power, multi phase controller. The second one would be the multiple power stages.

Speaker 7

That's the 50 kind of DRMOS that you've been talking about. And then the third would be this intermediate bus converter, which is is that the 48 volt to like 12 volt step down power? Am I framing that correctly?

Speaker 2

Actually, the first two are more of the same. So whether it's on an AI accelerated card or on a main board powering the GPU is still up to 50 power stages powering that. So that's the 1 the first two are the same and our customer will have different configurations, but in the end, it's still a point of load empowering the GPU itself. So the 2nd category, which I brought up just now is, yes, the intermediate bus converter using our medium voltage products. We actually have a number of other products also addressing going after AI.

Speaker 2

As a whole, actually AOS is very well connected into this ecosystem already, largely actually because we've already been we're already in the graphics as well as the computing ecosystem and a lot of that is shared. And to support this OEM, we're already working with the ODMs that are in Asia that are actually producing both boards as well as systems for this end customer. We're also engaged with the power supply maker that's making these intermediate bus converters. We're even addressing various fan makers as well regarding thermal management. So for us, this is actually AOS is very well suited to go after this market, both directly with OEM as well as indirectly with their suppliers.

Speaker 7

Got it. That's very helpful. And just to clarify again, is the controller, the multi based controller a piece of this or is that focused mainly on the consumer to craft?

Speaker 2

It is the GEDA product and especially as we move in as they move into their new platform, we are selling the total solution controller, multi phase controller in addition to the Power Stage.

Speaker 7

Got it. And could you size your opportunity here just from a potential SAM, whether it's on a per GPU basis? Any insights there would be very helpful.

Speaker 2

Sure. I'll quantify more at the board level what the content increases. And then the SAM will really depend on how fast they deploy and how many models they extend our solutions to. But as I mentioned before, on a graphics card, we use anywhere from 9 to 16 of these on a board. This number can go up to 50 powering each GPU.

Speaker 2

So it really just depends on the performance requirements of the card that's going into. So on content on a whole tripling at least per GPU and then just based on configuration, that's how much the opportunity can increase.

Speaker 7

And how about the intermediate bus converter opportunity as well as the controller opportunity?

Speaker 2

The controller is part of that. It's usually with a 1 controller pairing with those or multiple controllers pairing with those power stages. With the module solution, we're selling medium voltage MOSFETs going into it. So there's I don't really want to dollarize that here, but it's becoming something that's significant enough for us to talk about it in each of the second reports. So let me just put it that way.

Speaker 7

Got it. Very good. And just switching gears a little bit to the license and engineering. Is this from the license payments that you're receiving? I believe there was maybe $20,000,000 left a couple

Speaker 2

of quarters ago. Can you just give us

Speaker 7

an update how much license payments you're still to receive and how much of this was engineering versus licensing? Thank you.

Speaker 5

Sure. I mean, this contract is up to early 2025. So we still have like a couple of quarters to go. So that's the length of this agreement. So this agreement in total is for a 24 month period.

Speaker 7

And is the payment on a pretty consistent quarterly basis?

Speaker 5

No. Actually, some tied to the products, once we qualify them, fully verified by our customer and some portion is paid for our engineering services, which based on the annual basis, like every 12 months, they will

Speaker 7

pay. Got it. And is this figure included in the operating cash flow? Or is that

Speaker 6

kind of the same?

Speaker 3

Yes. Yes.

Speaker 5

That's in there. That's part of initially when we received the payment, we recorded as deferred revenue. And then because the revenue recognition is based on the engineering hours that we spent relative to the total estimated engineering hours. And so that's kind of varying each quarter. So we recognize revenue from our deferred revenue.

Speaker 7

Great. Thank you. I'll get back in the queue. Thank you very much.

Speaker 5

Thank you. Thanks.

Operator

Thank you. There are no additional questions left at this time. I will now hand it back to the management team for closing remarks.
