Supermicro shares surge after earnings beat, AI demand fuels upbeat forecast
What happened: Shares of Super Micro Computer (SMCI) surged more than 18% in Wednesday trading, marking their biggest single-day gain in months.
What’s behind the move: The company posted adjusted gross margins of 10.1% for its fiscal third quarter, sharply above the 6.75% analysts had penciled in. Revenue guidance for the current quarter also came in ahead of expectations, with the company forecasting net sales between $11 billion and $12.5 billion, versus the consensus estimate of $11.16 billion.
The jump reflects sustained demand for servers built to handle artificial intelligence workloads, particularly those equipped with Nvidia’s (NVDA) chips. As enterprises and cloud providers race to expand AI data center capacity, Supermicro has been a key beneficiary, though margin pressure has been a persistent concern. The latest numbers suggest that pressure may be easing.
What else you need to know: The stock has been a rollercoaster over the past year. In March, federal prosecutors accused Supermicro co-founder Yih-Shyan “Wally” Liaw of routing Nvidia-based servers worth billions of dollars to China in alleged violation of U.S. export controls. The company has also faced scrutiny over accounting practices and governance issues.
Despite those headwinds, Wednesday’s rally erased the stock’s year-to-date losses. Shares are now up more than 5% since the start of 2026.
Market reaction: “This is exactly what the bulls needed to see — margins are stabilizing, and the demand narrative is still intact,” said Mark Delaney, an analyst at a New York-based investment firm. “But let’s not pretend the legal and governance risks have gone away. That’s still a cloud over the story.”
Not everyone is convinced. “I’m sorry, but a 10% margin in a business that’s supposed to be riding the AI wave is nothing to celebrate,” said Linda Torres, a retail investor and frequent commentator on tech stocks. “This company has been a mess — accounting issues, export scandals, and now they’re patting themselves on the back for barely beating lowball estimates? Give me a break.”
Tom Hargrove, a portfolio manager at a midwest asset manager, took a more measured view: “The guidance is solid, and the demand environment is clearly strong. But Supermicro still trades at a discount to peers for a reason. Investors need to see consistent execution over several quarters before the risk premium narrows.”
