Upturn Advisory & Investor View for AOSL

09/25/2026: AOSL (1-star) is currently NOT-A-BUY. Pass it for now.

Alpha and Omega Semiconductor (AOSL) is a specialized designer and supplier of power semiconductor components used in computing, gaming, and industrial devices. The company has a notable position in the market due to its internal wafer fabrication capabilities, which allow for better quality and cost control than many peers of its size. Its primary investment story centers on expanding into higher-margin industrial and automotive markets while leveraging data center power demand. However, AOSL faces risks from intense competition by global semiconductor giants and high revenue concentration in cyclical consumer markets. The stock may suit investors seeking exposure to the power management cycle, though potential volatility should be monitored carefully.

Upturn Scorecard

Upturn Star Rating

★★★★★
AOSL receives a 3-star rating, supported by available scored pillars. The rating is constrained by soft unit economics, soft quantitative characteristics, and weak price momentum.

Company Fundamentals

★★★★★
AOSL has moderate overall fundamentals (3 stars), with moderate financial health, moderate growth momentum, and strong ownership. In FY2026 versus FY2025, strong earnings growth (+56.4%) is partially offset by soft cash generation (FCF margin -10.0%), slightly negative revenue growth (-2.5%), soft profitability (net margin -6.2%).

Financial Health Rating

★★★★★
AOSL's financial health is supported by solid liquidity, including working-capital and asset support (WC/assets 32.2%). Profitability is soft (2 stars), which helps explain the 3-star overall score.

Growth Momentum Score

★★★★★
Earnings growth is AOSL's strongest growth driver at +56.4% FY2026 versus FY2025 (strong, 5 stars). By comparison, while revenue growth (-2.5%, slightly negative) and free-cash-flow growth (-806.2%, negative) hold the profile back, so recent growth is not broad-based across the business.

Ownership

★★★★★
Institutional ownership is 76.9% and approximately 82.2% of outstanding shares are publicly tradable, supporting liquidity and institutional participation. Insider ownership of 7.01% supports management-shareholder alignment.

Manufacturers Life Insurance Co 5.20%
State Street Corp 4.63%
Dimensional Fund Advisors, Inc. 4.41%
Vanguard Portfolio Management, LLC 3.86%

Unit Economics (Per $1K Revenue)

★★★★★
AOSL generates approximately $223 of gross profit, $-64 of operating income, and $-100 of free cash flow for every $1,000 of revenue. Based on FY2026 results. Strong cash conversion and healthy margins support the rating, although capital efficiency remains below the highest tier.

Economic Dimensions

★★★★★
Effective Tax Rate: -22.52% (Tax Credit)

Quantitative Style Profile

★★★★★
AOSL has a liquid profile. Weak momentum is the primary drawback, while valuation that is moderately attractive rather than deeply discounted.
