The Justice Department is investigating Super Micro Computer, the Wall Street Journal reported Thursday, citing people familiar with the matter, sending the AI server maker’s shares down about 5%.
Super Micro Computer had earlier this month denied claims made in a report by short-seller Hindenburg Research, saying it contained “false or inaccurate statements” about the server maker.
Hindenburg in August disclosed a short position in Super Micro and alleged “accounting manipulation” at the company, citing evidence of undisclosed related-party transactions and failure to abide by export controls, among other issues.
Super Micro did not immediately respond to a Reuters request for comment.
