Alpha and Omega Semiconductor Limited (AOSL)
Data as of July 16, 2026
Environment story
AOSL discloses minimal environmental data. No Scope 1, 2, or 3 emissions figures, renewable energy percentages, or net-zero targets are documented in provided filings. The 10-K identifies operational risks (Oregon Fab energy requirements, packaging facility power consumption) but does not quantify carbon footprint or mitigation commitments. No environmental controversies, fines, or litigation appear in the 10-K. The company manufactures power semiconductors and operates fabrication and packaging facilities in the U.S. and China—sectors inherently energy-intensive—yet provides no decarbonization roadmap, renewable-energy procurement data, or supply-chain emissions accounting. Absence of disclosed ESG metrics triggers significant deductions under the deterministic rubric.

Disclosed initiatives
-
Manufacturing Operations Risk Management10-K acknowledges operational risks at Oregon Fab and Shanghai packaging facility, including equipment efficiency and power consumption; however, no energy efficiency improvements or renewable sourcing initiatives are disclosed.
Social story
AOSL provides no disclosed diversity metrics, CEO-to-worker pay ratios, or turnover rates in the 10-K. No labor union standing, workplace safety statistics, or supply-chain human-rights audits are reported. The company acknowledges reliance on a Shanghai packaging facility and third-party foundries in Asia, raising supply-chain labor exposure, but does not document audits or mitigation policies for conflict minerals, forced labor, or living wages. The 10-K notes dependence on senior management and key technical personnel, with no 'key person' insurance policies disclosed. No evidence of union suppression, strikes, or NLRB complaints within 24 months appears. Absence of diversity and labor-practices transparency results in a moderate score reflecting unknown but substantial social risks.

Disclosed initiatives
-
Employee Retention and Recruitment10-K states reliance on senior management and engineering talent; employment agreements exist for certain executives but most employees lack formal contracts. No structured DEI programs or supplier-diversity initiatives are disclosed.
-
Supply Chain OperationsCompany operates wholly-owned packaging and testing facility in Shanghai; relies on third-party foundries in Asia and JV Company in Chongqing for manufacturing capacity. No human-rights audit, conflict-minerals policy disclosure, or labor-standards certification reported.
Governance story
AOSL's 10-K does not disclose board composition, independence percentages, or share-structure details (single-class vs. dual-class voting). No lobbying expenditures, PAC contributions, or regulatory fines are reported. The company is incorporated in Bermuda and faces complex multi-jurisdictional tax and regulatory oversight (U.S., China, Taiwan, Hong Kong), generating governance complexity. The 10-K references debt covenants restricting certain actions (stock repurchase, acquisitions, capital expenditures) and compliance challenges with Chinese foreign-investment regulations and Bermuda corporate-tax law. No antitrust proceedings, SEC consent decrees, privacy fines, or consumer-protection litigation are disclosed. The absence of board-independence and share-structure disclosures, combined with Bermuda incorporation and geopolitical exposure, results in a moderate governance score reflecting material but unquantified risks.

-
Internal Control Over Financial Reporting10-K acknowledges requirement to maintain effective internal controls and adequate disclosure procedures; company has implemented cybersecurity measures in response to past incidents, though no material breaches are reported.
-
Regulatory Compliance FrameworkCompany operates across multiple jurisdictions (U.S., China, Taiwan, Hong Kong, Japan, Korea, India, UK, Germany) and manages transfer pricing, tax reporting, and foreign-investment compliance. Bermuda parent structure creates additional complexity under Bermuda Corporate Income Tax Act 2023 (15% CIT for multinational enterprises >€750M revenue; AOSL currently below threshold).
