Super Micro Computer Inc (NASDAQ:SMCI) shares opened about 20% higher on Tuesday after the company released preliminary fourth quarter fiscal 2026 results showing significantly stronger-than-expected gross margins and a record order backlog, despite revenue tracking near the low end of its guidance.
The AI server maker said revenue for the quarter ended June 30 is expected to be near the lower end of its previously issued guidance range of $11.0 billion to $12.5 billion. Wall Street analysts had been expecting revenue of about $11.73 billion.
Supermicro estimated GAAP and non-GAAP gross margins of 15% to 17%, well above its prior guidance of 8.2% to 8.4%. The company attributed the improvement primarily to a favorable customer and product mix.
The company also reported receiving more than $60 billion in new orders during the quarter, lifting its backlog to a record level at the end of fiscal 2026. Supermicro said the orders are expected to be delivered over future quarters.
Supermicro said it will release its complete Q4 fiscal 2026 financial results on August 11.
