SMCI: 10-for-1 stock split
Super Micro Computer shares fell 13% after the company’s fourth-quarter earnings missed estimates. The company, whose first-quarter revenue forecast exceeded Wall Street’s estimates, also announced a 10-for-1 stock split.

Super Micro is a key supplier of servers for Nvidia, a major player in the AI boom, and has seen significant growth in recent years. However, the company’s profitability is now a concern for investors. Its gross margin dropped to 11.2% in the reported quarter, down from 17%, a year earlier.

Microsoft vs Delta
Microsoft accused Delta Air Lines of outdated technology after an IT outage in July caused the airline to cancel more than 5,000 flights. The company, which said the incident had caused it $500 million in losses, is seeking damages from Microsoft and CrowdStrike.

A botched software update from CrowdStrike last month had affected millions of computers running Microsoft Windows. Microsoft questioned why Delta struggled to recover compared to other airlines, suggesting Delta hasn’t modernized its IT infrastructure. Delta refutes the claim.

X sues advertisers
Elon Musk’s X, formerly Twitter, is suing a group of advertisers for allegedly orchestrating an illegal boycott that cost the platform billions in revenue.

The lawsuit, filed in Texas, accuses the World Federation of Advertisers and its members of violating antitrust laws by stopping advertising after Musk’s takeover.

Musk, on X, declared “war” against the advertisers, while X CEO Linda Yaccarino cited evidence uncovered by the U.S. House Judiciary Committee to support the lawsuit’s claims.

Airbnb shares sink
Airbnb’s stock fell 14% in extended trading after its second-quarter earnings missed expectations. The company also warned of slowing growth, particularly in the U.S. It reported a net income of $555 million, or 86 cents per share, down 15% year-over-year from $650 million, or 98 cents per share.

The company projects third-quarter revenue of $3.67 billion to $3.73 billion but cautioned that it was “seeing shorter booking lead times globally and some signs of slowing demand from U.S. guests.”
