Super Micro Computer, Inc. (SMCI) has seen its stock price tumble by as much as 17% following reports from the Wall Street Journal that the U.S. Department of Justice (DOJ) has launched an investigation into the company. The probe comes in the wake of allegations of accounting manipulation raised by a short-seller's report, prompting increased scrutiny from regulators and investors alike. The situation has led to multiple class action lawsuits filed against Super Micro by concerned shareholders seeking recovery for their losses. The investigation and recent stock volatility have placed investors on edge, particularly as the company faces renewed scrutiny after delays in its annual report filings. Legal firms are actively reminding shareholders to discuss their rights and potential claims.
