SUPER MICRO COMPUTER INC 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 7% in premarket trading on Wednesday.

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.

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.

Quantum computing stocks rose in premarket trading on Wednesday. Rigetti Computing, D-Wave Quantum Inc. rose 4%; SEALSQ Corp, IONQ Inc. rose 3%; Quantum Computing Inc. rose 2.5%.

Lyft, Inc. fell 11% in premarket trading after the company forecasted current-quarter gross bookings below estimates on Tuesday, as its jostles for more riders with larger rival Uber Technologies, while wildfires and extreme weather events disrupted its business in some key markets.

Lyft said it was expecting gross bookings between $4.05 billion and $4.20 billion in the first quarter, below estimates of $4.26 billion.
