NEW YORK, July 21, 2026, 18:08 EDT – Supermicro shares climbed sharply in after-hours trading Tuesday following a preliminary margin adjustment that pointed to a significant increase in gross profit. The stock, which trades under the ticker SMCI on the Nasdaq, was at $29.90 at 18:02 EDT, representing a 17.3% gain after the regular session closed.
The company’s preliminary fourth-quarter guidance indicated a gross margin of 15% to 17%, a substantial improvement from the prior outlook of 8.2% to 8.4%. Based on the midpoint of the new margin range and projected revenue of $11.0 billion, gross profit would reach approximately $1.76 billion, up from the earlier estimate of $913 million. That translates to a potential $847 million increase, or roughly 93% higher than previously anticipated.
Revenue, however, came in at the lower end of the company’s forecast range of $11.0 billion to $12.5 billion, falling short of the analyst consensus of $11.67 billion. If revenue hits exactly $11.0 billion, it would be about 5.7% below expectations. The company attributed the margin expansion to a favorable customer and product mix, but did not provide a breakdown by client. The sustainability of this mix remains unconfirmed.
Orders provided another bright spot. New orders exceeded $60 billion during the quarter, more than 5.4 times the revenue floor. However, the company cautioned that these orders have not yet converted into sales and may not represent binding commitments, as they could be subject to cancellation or postponement. Capital remains a key focus: in June, Supermicro announced plans to raise $7 billion through equity and equity-linked financing to purchase components supporting approximately $39 billion in AI-server orders from over 20 clients.
The after-hours rally reversed recent losses. Between July 13 and July 17, the stock had declined by 12.6%. After Tuesday’s close, the price of $29.90 represented a 23.7% gain compared with Friday’s close. Combined with a 7.0% advance during the regular session, shares finished 25.5% higher than Monday’s closing level.
Complete results are scheduled for release on August 11. Investors will be looking for insights on order conversion, customer concentration, and cash requirements. Significant risks remain: an independent board is reviewing reported export-control matters, and the outcome could impact guidance or historical statements. All figures are preliminary and have not been audited; actual results may differ.
The strength of the rally hinges on the quality of margin improvement rather than faster sales growth. August’s report will be critical in determining whether the favorable mix persists.
