Supermicro shares rise after $60 billion AI server order update

Super Micro Computer Inc. said it booked more than $60 billion in new product orders during its fiscal fourth quarter, sending its shares up more than 19% in extended trading. The AI server maker also lifted its gross margin outlook sharply, a useful signal for a hardware business that has been under pressure to turn AI demand into profitable shipments.

The company, commonly known as Supermicro, said it now expects gross margin of 15% to 17% for the quarter ended June 30. Its earlier forecast called for a much thinner 8.2% to 8.4% range. Supermicro attributed the change to a more favorable mix of customers and products.

That is a large swing for a server vendor competing in a category where demand is strong but supply chains, working capital and customer concentration can all compress returns. Supermicro did not disclose which customers placed the new orders, how much of the total is tied to AI systems, or when the orders are expected to become revenue.

Revenue guidance is less aggressive

Supermicro said quarterly revenue is expected to come in near the low end of its prior $11 billion to $12.5 billion forecast. Analysts had been looking for $11.67 billion, according to the figures cited in the company update, leaving room for either a slight miss or a modest beat depending on the final number.

The company plans to report full quarterly and fiscal-year results on Aug. 11. Until then, investors have a margin upgrade, a large order figure and limited detail on the pace of fulfillment.

Management also said Supermicro’s backlog reached record levels at the end of fiscal 2026. That update follows a financing announcement just over a month earlier, when Supermicro said it planned to raise $7 billion through equity and equity-linked transactions. At the time, the company said it would use the capital to speed delivery of advanced AI servers for more than 20 customers and described an order backlog of more than $39 billion.

The market did not welcome that financing plan. Supermicro shares fell after the announcement, and even after the latest after-hours move, the stock remained down more than 16% over the past month.

AI infrastructure demand is still flowing to server makers

Supermicro has been one of the more visible hardware beneficiaries of the AI buildout outside the chip sector. Nvidia Corp. remains the central supplier in the market, while Advanced Micro Devices Inc. is also competing for AI accelerator demand. Server vendors such as Supermicro, Dell Technologies Inc. and Hewlett Packard Enterprise Co. sit closer to the system-integration layer, where enterprise and cloud infrastructure customers turn chips, cooling, networking and storage into deployable capacity.

Supermicro’s position has been helped by close ties to Nvidia and AMD, according to the company, which allow it to bring integrated AI servers to market. That relationship is commercially valuable if demand keeps exceeding supply. It also leaves the company exposed to the same constraints that affect the AI hardware chain, including component availability, customer delivery schedules and the capital needed to carry large orders.

The latest update gives Supermicro a stronger margin story than investors were expecting. The open question is how quickly the company can convert a larger backlog into recognized revenue without repeatedly returning to capital markets to fund the buildout.
