Super Micro Computer's annual report, its 10-K filing, was due on Aug. 29, and the company has yet to file it. Providing audited financials can take time for a company, especially when the auditor is new, as opposed to an auditor who is already familiar with the business.

Super Micro has engaged BDO as its auditor, replacing Ernst & Young, which resigned in October after it raised concerns regarding the company’s financial statements.

Super Micro Computer Inc.’s stock tumbled 7% Friday to lead S&P 500 decliners in the holiday-shortened session, capping a turbulent November for the stock.

With no SEC filings, Super Micro Computer is now at risk of getting delisted from the Nasdaq exchange. The company has 180 days to file its annual report past the due date once it formulates a plan with the Nasdaq regulators. If it doesn't, the stock will get dropped from the exchange.
