The U.S. Department of Justice is investigating Super Micro Computer (SMCI.O), the Wall Street Journal reported on 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.
Super Micro did not immediately respond to a Reuters request for comment.
