Shares of Super Micro Computer (SMCI) fell sharply in premarket trading on Wednesday.
The decline came after the server maker announced plans to raise $7 billion through a series of equity and equity-linked financing offerings to support growing demand for artificial intelligence infrastructure.
The stock dropped 11.4% to $36 in premarket trading.
The decline came after the company disclosed plans to issue new shares and preferred securities to fund purchases of components needed to fulfill a rapidly expanding backlog of AI server orders.
The fundraising announcement arrives as demand for AI hardware continues to surge, but it also highlights the growing costs associated with expanding capacity to meet that demand.
Company plans $7 billion capital raise
Super Micro said it intends to raise $5 billion through underwritten offerings and an additional $2 billion through an at-the-market (ATM) program expected to begin no earlier than the third quarter.
The underwritten portion includes a $1.25 billion common stock offering and $3.75 billion of depositary shares representing interests in newly issued mandatory convertible preferred stock.
The company said the proceeds will be used to purchase components required to fulfill recent AI server orders.
According to the company, it has received approximately $39 billion in AI server orders from more than 20 customers.
The orders reflect continued demand for AI systems equipped with Nvidia chips, a market segment that has become one of the fastest-growing areas of enterprise technology spending.
Super Micro said the capital raise will help fund the inventory and components necessary to support those orders as customers continue expanding AI infrastructure.
AI growth comes with mounting costs
Super Micro has emerged as one of the major beneficiaries of the AI boom.
Revenue in the March quarter more than doubled from the same period a year earlier as demand for AI servers accelerated.
However, the company’s rapid growth has placed pressure on its balance sheet and cash flow.
Over the 12 months ended March 2026, Super Micro generated negative free cash flow of $6.8 billion.
The business remains capital-intensive, requiring significant upfront investment in components and manufacturing capacity before revenue is realized.
The company has also faced rising input costs. Chief executive Charles Liang told analysts in May that memory costs had more than tripled in recent months.
The fundraising effort underscores the challenge many AI infrastructure providers face as they attempt to keep pace with demand while managing rising costs and working capital requirements.
Investors weigh dilution concerns
While the new capital will help support growth, investors reacted negatively to the prospect of shareholder dilution.
Equity offerings typically increase the number of shares outstanding, reducing the ownership percentage of existing shareholders.
As a result, companies often see short-term pressure on their stock prices following such announcements.
The broader technology sector was also under pressure. S&P 500 futures fell 0.4% as investors continued rotating away from some AI-related stocks.
Super Micro shares had already fallen 7.6% on Tuesday amid broader weakness across the AI sector.
Rival server maker Dell Technologies was also lower in premarket trading, falling 2.1%.
Despite the recent pullback, Super Micro remains one of the stronger-performing AI-linked stocks this year.
Shares are still up 31% year to date, supported by expectations that demand for AI servers and related infrastructure will continue to grow.
