Super Micro Computer (SMCI) stock fell about 10% in after-hours trading on Tuesday after the company's outlook for both earnings per share and sales in the current quarter missed Wall Street's estimates.

Additionally, Super Micro still hasn't filed its 10-K annual report, which it initially pushed back in late August. The company said it "remains unable at this time to predict when the Form 10-K will be filed."

Super Micro said it expects adjusted earnings per share of $0.56 to $0.65 in its fiscal second quarter, below consensus estimates of $0.80, per Bloomberg data. Meanwhile, Super Micro's forecast for net sales in a range of $5.5 billion to $6.1 billion was weaker than the $6.79 billion on Wall Street had expected.

The earnings came less than a week after accounting firm Ernst & Young (EY) resigned as Super Micro's auditor. EY said in a filing it was "unwilling to be associated with the financial statements prepared by management."

Super Micro responded to those accusations on Tuesday with a response from an independent "special committee" that had been investigating the accusations.

"Following a three-month investigation led by Independent Counsel, the Committee’s investigation to date has found that the Audit Committee has acted independently and that there is no evidence of fraud or misconduct on the part of management or the Board of Directors," the release said. "The Committee is recommending a series of remedial measures for the Company to strengthen its internal governance and oversight functions, and the Committee expects to deliver the full report on the completed work this week or next."

EY's resignation came two months after a short report from Hindenburg Research alleged, among other things, "accounting manipulation" at the artificial intelligence highflier.

After the stock rallied earlier in the year as investors cheered SMCI's prospects in the AI data center space, shares are now down more than 60% over the past six months.

In August, Hindenburg said its three-month investigation "found glaring accounting red flags, evidence of undisclosed related party transactions, sanctions and export control failures, and customer issues." The firm also disclosed it had taken a short position in Super Micro.

After that report, Super Micro delayed the filing of its annual report, which sent the stock nearly 20% lower in late August.

In September, the Wall Street Journal reported the US Department of Justice is investigating Super Micro Computer. The Journal reported the probe was in an "early stage," citing people familiar with the matter. Additionally, the Journal said a prosecutor at the US attorney’s office in San Francisco had asked for information regarding a former employee who was accused of accounting violations.
