Supermicro Stock Soars 20% on Massive Margin Beat and $60 Billion Order Influx

Super Micro Computer (NASDAQ: SMCI) shares rocketed over 20% in after-hours trading Tuesday after the company's preliminary fourth-quarter update revealed a dramatic expansion in profitability and a record order backlog. The positive indicators overshadowed revenue projections that are expected to land at the low end of the company's guidance.

Margin and Backlog Steal the Show

In its update for the quarter ended June 30, 2026, Supermicro announced it expects a significant increase in its gross margins. The AI server and infrastructure provider projected both GAAP and non-GAAP gross margins to be between 15% and 17%, a substantial jump from its previous forecast of 8.2% to 8.4%. Management attributed this expansion to a "highly favorable product and customer mix."

Furthermore, the company disclosed that it secured a staggering $60 billion in new orders during the fourth quarter alone. This pushed its order backlog to an all-time high at the close of its 2026 fiscal year, signaling a massive pipeline of future demand to be fulfilled in the coming quarters.

Revenue Guidance Overlooked

The blockbuster margin and order figures eclipsed the company's more cautious top-line forecast. Supermicro stated it expects revenue to be near the bottom of its previously announced range of $11.0 billion to $12.5 billion.

Investor reaction indicates a clear focus on profitability and the long-term demand for AI infrastructure. The market appeared to prioritize the strong bottom-line execution and unprecedented backlog over the slight softness in near-term revenue, reinforcing bullish sentiment around the AI sector.

Supermicro is scheduled to release its complete fourth-quarter and full fiscal year 2026 financial results during its earnings call on August 11 at 5:00 p.m. EDT.
