Super Micro Computer loses over 40% of value after short-seller report

Super Micro Computer, one of the biggest beneficiaries of the AI infrastructure boom, saw its stock crater after short-seller Hindenburg Research published a damning report alleging accounting irregularities, undisclosed related-party transactions, and potential export control violations.

What Hindenburg found, and why it mattered

Hindenburg Research published its report on August 27, 2024. The firm described Super Micro’s financial practices as having “glaring accounting red flags.”

The specific allegations were serious. Hindenburg pointed to accounting discrepancies, related-party transactions the company allegedly failed to disclose, and potential violations of export controls tied to shipments to Russia.

The stock dropped more than 30% in the immediate aftermath.

The company was previously delisted from Nasdaq back in 2018 because it couldn’t file its financial statements on time.

The damage kept compounding

In June 2026, SMCI announced plans to raise $7 billion through equity-related financing. The stated purpose was to support its substantial AI server orders. The stock dropped 13% in a single day on that announcement alone.

As of late May 2026, short interest in SMCI sat at approximately 74.5 million shares. That represented about 14.76% of the company’s float.
