(Reuters) - Super Micro Computer said on Tuesday it believes it will be able to file delayed annual and quarterly reports with the U.S. Securities and Exchange Commission (SEC) by February 25, sending its shares up over 8% after the bell. 

The server maker said it had received subpoenas from the U.S. Department of Justice and the SEC seeking certain documents following short seller Hindenburg Research's allegations of "accounting manipulation" in August. It is cooperating with the requests.

The San Jose, California-based company also cut its annual revenue forecast, mainly due to delays in the availability of Nvidia's Blackwell processors.

While the delay in filing the 10-K report was a "distraction", the biggest factor was the delay in the availability of the technology, said Super Micro's financial chief David Weigand during a conference call with analysts.  

Super Micro announced the full production availability of its AI server systems powered by Nvidia's Blackwell chips last week.

Super Micro, which has so far been one of the beneficiaries of a spending surge on advanced data center architecture that can support the complex processing needs of GenAI, faces intensifying competition from rivals such as Dell and HP Enterprise.

The company expects net sales between $23.5 billion and $25 billion for fiscal 2025, down from its earlier projection of $26 billion to $30 billion. 

The midpoint of the forecast is $24.25 billion, below analysts' expectation of $24.92 billion in annual revenue, according to data compiled by LSEG. 

For the third quarter, Super Micro expects net sales of $5 billion to $6 billion, compared with analysts' estimate of $6.09 billion.

Super Micro was removed from the tech-heavy Nasdaq-100 Index in December, after receiving an extension from the Nasdaq, till February 25, to file its delayed annual and quarterly reports, after failing to submit the 10-K report by the August deadline.
