Silicon Valley-based AI server maker Super Micro Computer was slapped last Friday with a lawsuit claiming that it violated federal securities laws by misleading investors about its compliance with trade restrictions on Russia, among other alleged offenses.

The Norfolk County Retirement System, based in Canton, Massachusetts, filed the class action  in the U.S. District Court for the Northern District of California in San Jose. The class, which includes those who acquired Super Micro Computer securities between February 2, 2021 and Sept. 25, 2025, is represented by counsel from Hagens Berman Sobol Shapiro and Labaton Keller Sucharow. The company's CEO, Charles Liang, and Chief Financial Officer, David Weigand, are listed as co-defendants.
