Super Micro stock plunges after plans for $7 billion capital raise to fund AI backlog

Global leader in AI and computing, Super Micro Computer (SMCI) has had its shares fall by about 10% in after-hours trading on Tuesday after the server maker announced plans to raise $7 billion in new financing to fund its growing AI hardware backlog.

The capital raise involves two phases, with the initial phase being an immediate launch of a $5 billion underwritten public offering in addition to a later $1.25 billion in common stock. A $3.75 billion in depositary shares raise tied to newly issued mandatory convertible preferred stock is expected afterward.

A separate $2 billion at-the-market equity program, managed by major Wall Street banks, is set to begin no earlier than the third quarter of 2026.

Super Micro said it needs the cash to buy components for roughly $39 billion worth of advanced AI server orders it has received from more than 20 customers. The orders cover AI servers and what the company calls Data Center Building Block Solutions.

Why are investors selling SMCI?

A $7 billion raise for a company whose market capitalization already sat near $34 billion before the announcement represents a substantial ownership hit for existing shareholders. This has led to a dilution of ownership shares and explains the general initial reaction.

Super Micro’s plans are also one of the clearest illustrations yet of how capital-intensive the AI infrastructure buildout has become. Getting $39 billion in orders sounds bullish until the company reveals it cannot fulfill those orders without initially raising billions to secure parts to build these orders.

AI hardware manufacturers are in a rather delicate and unusual situation, as demand is enormous, almost as enormous as the upfront costs required to meet this demand. Global supply chains for high-end AI components also remain very tight and between a few companies.

Super Micro flexibility and capital bets

The staggered structure of the planned raise offers Super Micro some flexibility, and holding the $2 billion at-the-market raise program until the third quarter of 2026 allows management to pace share purchases. This speed will be based on conditions surrounding the purchasing of components and parts, as well as how the previously discussed supply chains evolve over the coming quarters.

Investors will also be tracking how quickly Super Micro converts its $39 billion production backlog into consistent revenue. This will be determined by the company’s ability to secure these scarce AI chips and related components on favorable terms while getting their orders delivered on time.

Super Micro’s next quarterly earnings report should provide the first concrete update on the progress on procurement of the important parts. SMCI price sits at $40.64 as of the time of writing.
