How much of the strong Advanced Computing growth in Q4 and Q1 FY27 outlook is driven by new program wins versus ramps of existing sockets?

The growth is a combination of both new program wins and ramps of previous sockets. The company is serving a more diversified customer base, including hyperscalers and data center power supply providers, with products ramping across various customers and programs. “I would say it's a little bit of both. The benefit -- one of the great things about going into this market now is that we are serving a more diversified customer base.”

What is the timing for 800-volt solutions to become a material revenue contributor? Will it be in 2027 or later?

It's too early to forecast materiality. While 800-volt is 'right around the corner' and some business might be seen next year, it will be a phased transition alongside existing 48-volt platforms, which will coexist for a while. “I wouldn't be surprised that if next year, we see some business come for those applications. But this won't be like a 0, 1, and 1 and 0 for the standard solutions, and these will be phased in alongside with the other programs.”

Is the Q1 FY27 non-GAAP OpEx guide of $46.5 million the new run rate, or should further increases be expected for R&D investments?

The company has been gearing up R&D investments, primarily in AI and total solutions for PC and smartphones. While Q1 FY27 reflects this, modest growth in OpEx is still expected beyond the December quarter as the company continues to fill necessary positions. “I would say December going forward, we still have to fill positions we need to fill. So I would say probably some modest growth there.”

Q&A highlights

What are the contributions of utilization and product mix to the sequential gross margin improvement in Q4 and the Q1 FY27 guidance? What is the current utilization rate?

The Q4 FY26 gross margin improvement was primarily due to better product mix, with a smaller portion from utilization and operating expenses. The Q1 FY27 guided improvement is mainly from better product mix, also factoring in the typhoon impact. No specific utilization rate was provided.

“For the September quarter, we guided another 70, 80 basis points up. So primarily, it was considering the product -- better product mix. So we also factor in some of the impact from this typhoon impact on our back-end factory.”

Detailed narrative

Advanced Computing Momentum

Alpha and Omega Semiconductor delivered strong performance in Advanced Computing, with revenue increasing 35% sequentially in Q4 FY26. This segment, encompassing AI, server, workstation, and cloud applications, now represents a record 31% of the Computing segment. The company anticipates continued robust growth, projecting over 40% sequential growth for Advanced Computing in Q1 FY27, with the AI and server business alone expected to surge by more than 60% sequentially.

This expansion is driven by growing engagement with power supply providers, module makers, ODMs, cloud service providers, and hyperscale customers, indicating broad customer traction and design activity.

Strategic Mix Shift and Profitability

The company's strategic transformation towards higher-value applications is yielding results, with Advanced Computing products contributing significantly to both revenue and earnings. The high-performance MOSFETs and medium-voltage solutions sold into AI and server applications command better pricing and margins due to their performance-critical nature and reduced competition.

This mix shift is expected to support higher gross margins in the second half of calendar 2026, reinforcing the benefits of prior strategic investments and positioning AOS for more profitable long-term growth.

Market Headwinds and Offsets

While Advanced Computing thrives, traditional markets face challenges. The PC market is experiencing softness due to elevated memory costs and CPU shortages, leading to an expected 'flattish' sequential growth for the overall Computing segment in Q1 FY27, despite Advanced Computing's strength.

The Consumer segment also saw a 21.3% YoY decline in Q4 FY26, primarily from a maturing Gaming console cycle, and is projected to decline 25% sequentially in Q1 FY27. In Communications, elevated memory pricing and supply constraints are pushing some OEMs towards lower-performance components, though AOS's focus on premium smartphone platforms and high-performance sockets helps mitigate these pressures.

Operational Investments and Capacity Expansion

AOS is actively investing to capitalize on growth opportunities, particularly in AI infrastructure. The company is expanding its medium-voltage manufacturing capacity and increasing targeted R&D investments for next-generation AI solutions. These efforts are building a growing pipeline of new products across AI-related workloads, aiming to deliver a broader product portfolio, increased content per platform, and sustained technological leadership.

R&D expenses are expected to see modest growth beyond Q1 FY27 as the company continues to fill positions.

Typhoon Impact on Near-Term Outlook

A recent Typhoon Dolphin impacted portions of the company's Shanghai packaging operations, causing a slight disruption to the near-term outlook. Management estimates an initial impact of a 'few million dollars' to Q1 FY27 revenue and some effect on margins. Teams are actively working to restore effective capacity, minimize customer disruption, and recover delayed business in subsequent quarters, demonstrating agility in managing unforeseen operational challenges.
