Cerebras Systems Inc. Class A Common StockQ2 revenue missed expectations, stock tumbled 14% despite raised guidance; analysts trimmed price targets.

Cerebras Systems shares tumbled about 14% in extended trading on August 12, 2026, even after the AI chipmaker's second-quarter revenue rose 74.3% year over year to $180.1 million and it raised full-year guidance for the second time since its May 2026 IPO. The revenue figure missed the $194.2 million analysts expected, according to LSEG, while the adjusted loss narrowed sharply to 5 cents a share, well inside the 17 cents modeled. CEO Andrew Feldman said AI demand is "through the roof," and the company lifted its full-year core revenue guidance to $880 million to $890 million, up from $855 million to $865 million, and raised its annual adjusted gross margin target to 41% to 43% from 38% to 41%. Hardware sales, including its core AI chips, declined to $54.1 million from $70.3 million a year earlier, meaning more growth now comes from renting back its own systems to cloud customers than from selling chips outright. Cerebras posted a GAAP net loss of $450.5 million for the quarter, compared with a $309.5 million profit a year earlier, though most of that swing came from $386.6 million in stock-based compensation costs. Morgan Stanley analysts said "execution remains the key debate" given the scale and speed of the capacity buildout required, and both Citi and Mizuho trimmed their price targets after the results. Cerebras and Advanced Micro Devices partnered in July 2026 to combine their chips in AMD's Helios AI systems, with Feldman saying the combined system delivers five times higher tokens per second per watt than competing setups.
