Looking at the full Fiscal Year 2025, which ended on June 30, 2025, Alpha and Omega Semiconductor Limited reported total revenue of $696.2 million, marking a 5.9% increase from the prior fiscal year. However, the bottom line reflected a net loss of $97.0 million for the year, which was a widening of the loss by $85.9 million compared to Fiscal Year 2024. For that full year, the only reported revenue segment was The Design, Development and Supply of Power Semiconductor Products, which brought in that $696.2 million.

The fourth quarter of Fiscal Year 2025 showed some strong momentum, with revenue hitting $176.5 million, up 9.4% year-over-year. That quarter was particularly strong in the Power IC segment, which achieved record quarterly revenue, growing 30.2% year-over-year and now making up nearly 40% of total product revenue. The Computing segment, fueled by AI and graphics chips, was the largest part of the business, representing 52.6% of total revenue in that quarter.

As of the latest reported data for the fiscal first quarter of 2026, which ended on September 30, 2025, Alpha and Omega Semiconductor Limited posted revenue of $182.5 million, which was flat compared to the same quarter last year but up 3.4% sequentially. The Power IC segment continued its strength, showing 37.3% year-over-year growth. The company closed that quarter with $223.5 million in cash and cash equivalents, and shortly after, in mid-November 2025, announced a $30 million share repurchase program.

Alpha and Omega Semiconductor Limited (AOSL) - BCG Matrix: Stars

You're looking at the engine room of Alpha and Omega Semiconductor Limited (AOSL)'s current growth, the Stars quadrant. These are the business units commanding high market share in markets that are still expanding rapidly. They are the leaders right now, but honestly, they drink a lot of cash to maintain that lead.

The Power ICs for AI/Graphics segment is a prime example of a Star for Alpha and Omega Semiconductor Limited (AOSL). This area hit a record revenue of $68.7 million in Q4 2025, representing a year-over-year growth of 30.2%. This segment's success is clearly driving the improved product mix that boosted the non-GAAP gross margin to 24.4% in Q4 2025. If this high-growth market eventually slows down, this unit is positioned to become a Cash Cow, but for now, it demands investment to keep that market share.

The broader Power solutions for Advanced Computing segment is the largest contributor to the top line, making up 52.6% of total Q4 2025 revenue. Within that, the AI and graphics chips-the core of the Star activity-account for about 25% of that segment's revenue. The company is definitely putting resources here to maintain its leadership position in these high-demand areas.

Here's a quick look at the key metrics for the leading Star component:

The strategy here is clearly to invest heavily to secure the market leadership. This involves developing more sophisticated components, like the High-performance power stages. These leverage integrated IC and discrete technology specifically for high-density server and data center applications, which are defintely high-growth end markets.

Also showing Star characteristics, though perhaps slightly less dominant than the AI/Graphics driver, are the Solutions for high-current quick chargers. The content per device in this area is increasing, which drives strong sequential growth in the communications end-market. This indicates that Alpha and Omega Semiconductor Limited (AOSL) is successfully capturing more value in each unit sold.

You can see the focus on these growth areas through the company's recent capital actions. The planned sale of a stake in the Chongqing joint venture for $150 million is explicitly mentioned as providing capital to continue investing in technology and equipment to support these key growth areas.

Key characteristics supporting the Star categorization for these units include:

• Power IC revenue reached a record quarterly high.
• Strong sequential growth in AI and graphics chips noted by management.
• Continued momentum in wearables contributing to segment strength.
• High-current charger solutions showing strong sequential growth.
• The segment is leading to a richer product mix, benefiting margins.

Alpha and Omega Semiconductor Limited (AOSL) - BCG Matrix: Cash Cows

Cash Cows are the bedrock of any strong portfolio; they are the business units or products that have already won their market and now just need maintenance to keep the cash flowing. You want these units to generate more cash than they consume. For Alpha and Omega Semiconductor Limited (AOSL), several established product lines fit this profile, operating in mature markets where their high market share provides a durable advantage, even if the overall market growth is modest.

These segments require minimal investment in aggressive promotion because their market position is already established. Instead, the focus shifts to operational efficiency improvements to maximize the cash yield from these steady performers. The cash generated here is what funds the riskier bets, like the Question Marks, and supports the entire corporate structure.

Here's a look at the key areas that function as Alpha and Omega Semiconductor Limited (AOSL)'s Cash Cows as of the fiscal year 2025:

• Core Power Discrete (MOSFETs): This is the largest historical product category, serving as the company's stable revenue foundation.
• Computing segment's legacy PC/Notebook power solutions: These products maintain market leadership in mature, lower-growth PC markets, providing high volume.
• Consumer segment's products for TVs and general home appliances: These deliver steady, high-volume sales in markets showing predictable, low single-digit growth.

The overall business performance in FY 2025 demonstrates this scale, with the full-year revenue reaching $696.2 million, which was an increase of 5.9% from fiscal year 2024. This growth, despite a challenging environment, shows the underlying strength of these established product lines.

The segment performance data for the fiscal year ended June 30, 2025, highlights the volume-driven nature of these mature businesses. While the average selling price (ASP) saw an 8.0% decrease, unit shipments increased by 17.1%, which is defintely a sign of maintaining market presence in high-volume areas. Specifically, power discrete product sales grew by 5.5%, and power IC product sales increased by 11.7%, contributing significantly to the total revenue.

To give you a clearer picture of the financial context surrounding these cash-generating units for the full year 2025, here are the key figures:

The strategy here is to invest just enough-perhaps in infrastructure to lower the cost of sales, which was 77% of total revenue at $535.2 million-to keep these products competitive and efficient. You want to milk these gains passively, ensuring they continue to fund the rest of Alpha and Omega Semiconductor Limited (AOSL)'s strategic moves.

The focus for these Cash Cows should be on maintaining productivity levels, not on aggressive expansion. For instance, the legacy PC/Notebook power solutions are in a market where growth is inherently low, so any investment should target process improvements to keep the 23.1% gross margin as healthy as possible, or better.

Alpha and Omega Semiconductor Limited (AOSL) - BCG Matrix: Dogs

Dogs are units or products with a low market share and low growth rates. They frequently break even, neither earning nor consuming much cash. Dogs are generally considered cash traps because businesses have money tied up in them, even though they bring back almost nothing in return. These business units are prime candidates for divestiture.

Legacy AC/DC power supplies fall into this category, operating in a highly commoditized, low-margin market with limited growth prospects. While specific revenue for this sub-segment isn't broken out, the overall pressure on margins suggests these legacy products are not driving the high-growth Power IC revenue which reached 30.2% year-over-year growth in Q4 2025.

Certain traditional power tools applications showed weaker than expected demand in Q4 2025, indicating market saturation or share loss within that specific end-market application. This contrasts sharply with the Computing segment, which grew 29.7% year-over-year in Q4 2025, highlighting the relative stagnation of these traditional areas.

General purpose, low-performance discrete components are in an intensely competitive market, contributing to gross margin pressure. The reported Q4 Non-GAAP Gross Margin was 24.4%, which, while an improvement sequentially from 22.5% in the prior quarter, was down from 26.4% a year ago, reflecting the mix impact away from these lower-value parts.

The Licensing and engineering services revenue stream is a clear example of a Dog being divested; this revenue stream wound down in the March 2025 quarter, ending a low-growth, non-core income source. The removal of this revenue stream, which was non-core, aligns with minimizing commitments to units that do not contribute significantly to growth or cash flow.

Here's the quick math on the financial context surrounding the end of Q4 Fiscal Year 2025:

You need to recognize the characteristics that place these product areas in the Dogs quadrant:

• Market growth rate: Low for legacy and commoditized segments.
• Relative market share: Low against higher-performing Power IC products.
• Strategic action: Divestiture or minimization of investment.
• Margin impact: Contributes to overall gross margin pressure below 26.4% (Y/Y Q4 comparison).
• Cash flow: Frequently break-even or cash traps.
