Applied Materials, the largest producer of wafer fab equipment in the U.S., said in a filing with the U.S. Security and Exchange Commission that it had received multiple subpoenas from various government agencies over shipments of its products to certain customers in China. At least one subpoena could be related to shipments to SMIC, a major China-based foundry that is blacklisted by the U.S. government.
"We have received multiple subpoenas from government authorities requesting information relating to certain China customer shipments," the filing by Applied Materials reads. "In August 2022 and February 2024, we received subpoenas from the U.S. Attorney’s Office for the District of Massachusetts; in November 2023, we received a subpoena from the U.S. Commerce Department’s Bureau of Industry and Security; and in February 2024, we received a subpoena from the U.S. Securities and Exchange Commission. […] We are cooperating fully with the government in these matters. These matters are subject to uncertainties, and we cannot predict the outcome, nor reasonably estimate a range of loss or penalties, if any, relating to these matters.
