What happened?
On May 14, 2026, Cerebras conducted its initial public offering ("IPO"), selling 30 million shares of common stock at $185.00 per share.
On June 24, 2026, Cerebras released its first quarter 2026 financial results, missing estimates, and disclosing that "[f]or the rest of 2026, in order to accelerate [the Company's] ability to service the significant near-term demand in [its] contracted backlog, [it has] chosen to make more capacity available sooner by temporarily renting [its] own systems back from an existing customer while [it] aggressively build[s] out and deploy[s] [its] own data center capacity." Further, the Company revealed that "[t]he additional cost of renting third-party capacity will depress core Cloud and other services margin temporarily from current levels."
On this news, Cerebras' stock price fell $44.46, or 19.6%, to close at $182.26 per share on June 24, 2026, thereby injuring investors.
Then, on October 28, 2026, Culper Research published a report regarding Cerebra’s chips’ durability and its depreciation assumptions. The report alleges that Cerebras’s wafer-scale chips last only 1.5 to 2.5 years in the field due to thermal expansion issues from continuous “dummy operations” so the chips never cool. Culper says draft IPO filings through December 2025 gave equipment useful lives of 1.5 to 3 years, and that four months later Cerebras nearly doubled them to 3 to 5 years, inflating margins.
On this news, Cerebras’ stock fell $6.75 or 5.66% to close at $112.56 on October 28, 2026, thereby further injuring investors.
"The price of Cerebras Systems Inc. shares fell 19.6% following the June 24, 2026 disclosure that Cerebras had missed first quarter 2026 estimates and would temporarily depress its core Cloud and other services margin by renting third-party capacity, including its own systems back from an existing customer. Investors who suffered losses deserve to know whether they were given complete and accurate information prior to the disclosure, and our investigation seeks to answer that question," said Charles H. Linehan, Partner at Glancy Prongay Wolke & Rotter LLP.
