Cerebras shares plummet 16% after results fail to impress investors

On August 12, AI chip designer Cerebras Systems experienced a 16% drop in shares following quarterly results that fell short of investor expectations. The stock had surged over 41% since its IPO, driven by expectations that its specialized chips could rival Nvidia's expensive processors. Cerebras concluded its second earnings report as a publicly traded company, highlighting the need for investors to accurately assess the company's potential to scale profitably.

The company's adjusted gross margin in the June quarter was 5 percentage points lower, with higher costs incurred for renting computing capacity. Despite this, Cerebras raised its annual revenue and gross margin projections and confirmed it was not experiencing severe supply shortages as other chip designers. The company's flagship wafer-scale engine, a single chip the size of a dinner plate, is designed to be more efficient than Nvidia's approach of connecting numerous smaller graphics processors.

CEO Andrew Feldman stated that memory directly on the chip had alleviated the impact of rising memory prices. Nvidia's rising prices, attributed to high-bandwidth memory (HBM), were cited as a contributing factor to Cerebras' success. Advanced AI chip production is concentrated at TSMC, with Cerebras benefiting from lower supply pressures due to its use of TSMC's 5-nanometer process.

The company expects to more than triple revenue in 2027 and aims to generate between $880 million and $890 million in adjusted revenue for the 2026 fiscal year.
