Rhea-AI Summary

Alpha and Omega Semiconductor Limited reported fiscal third-quarter 2026 revenue of $163.8 million, up 0.9% sequentially but down 0.5% year over year, reflecting strength in Advanced Computing and U.S. smartphones offset by softer PC and consumer demand. GAAP gross margin was 21.1% and the company recorded a GAAP net loss of $13.8 million, or $0.46 per diluted share. On a non-GAAP basis, gross margin was 21.7% and net loss was $8.3 million, or $0.28 per share, with profitability pressured by lower utilization and higher costs.

Management highlighted strong growth in Advanced Computing, where AI, server and graphics-related revenue more than doubled sequentially and grew over 40% year over year, and continued content gains with a Tier One U.S. smartphone customer. Operating cash flow for the quarter was an outflow of $8.3 million, and the company ended the period with $190.3 million in cash and cash equivalents. For fiscal fourth quarter 2026, AOS expects revenue around $168 million plus or minus $10 million, GAAP gross margin of 22.3% (non-GAAP 23.0%), and non-GAAP operating expenses near $45.5 million.
