Alpha and Omega Semiconductor has agreed to pay $4.25 million to settle a U.S. Department of Commerce investigation over unauthorized shipments to Huawei Technologies in 2019, according to a department order posted Wednesday.
The Commerce Department said the company violated export regulations by sending 1,650 power controllers, smart power stages, and accessories to Huawei without approval. Huawei was added to the U.S. Entity List in 2019, and companies are required to obtain licenses before exporting to firms on the list.
Although the items were foreign-designed and produced, they were shipped from the United States, making them subject to U.S. export rules.
In a statement, Alpha and Omega Semiconductor said the settlement ends the Commerce Department’s civil investigation and does not affect its current operations. The company said it was pleased to resolve the matter with only administrative export control charges.
The Justice Department had earlier investigated the same transactions but closed its case in January 2024 without filing charges. The Commerce Department continued its civil probe, which led to the settlement.
The company received a letter in April 2025 from the Commerce Department detailing the alleged violations, and later met with officials to discuss resolution.
Alpha and Omega Semiconductor is based in Sunnyvale, California, and operates in both the U.S. and Asia. It also has a wafer fabrication facility in Hillsboro, Oregon.
In 2020, the U.S. government expanded its restrictions to cover more foreign-produced items going to Huawei.
