Cerebras Stock Drops 16% After Sales Fall Short of Expectations

Cerebras Systems, a company that makes special computer chips for artificial intelligence, saw its stock price fall 16 percent after the market closed on Wednesday, August 12. The drop happened because the company's sales for the spring quarter were lower than what Wall Street experts had predicted. Even though Cerebras had a strong regular trading day — rising nearly 12 percent — investors quickly changed their minds once the earnings numbers came out. The reaction showed that investors are watching AI companies very closely and are quick to sell shares when results disappoint.

Cerebras is based in Sunnyvale, California, and makes a very unusual kind of AI chip. Its main product, called the wafer-scale engine, is a single chip about the size of a dinner plate. It contains trillions of tiny parts called transistors and is designed to work more efficiently than linking thousands of smaller chips together, which is how rival Nvidia builds its systems. Cerebras says its design gives it an edge in the growing AI market.

The company has only been publicly traded for a short time, and this was just its second report to investors since going public. Its stock had already climbed more than 41 percent above the price it was sold at during its IPO, or initial public offering. That big gain was driven by excitement about AI and hope that Cerebras could compete with Nvidia, which is the top company in the AI chip market. But missing the revenue target reminded investors that the company still has a lot to prove.

Cerebras made $180.11 million in sales during the quarter, which ended June 30. That sounds like a lot, but analysts had expected $194.23 million, so the company came up short by about $14 million. Its cloud business, which lets customers rent access to its chips over the internet, nearly quadrupled to $126 million compared to the same time last year. However, its hardware sales — the physical chips it sells — dropped from $70.3 million to $54.1 million.

One reason profits were squeezed was that the company had to spend more money renting computing space it had previously used for other customers. This pushed the company's adjusted gross margin — a measure of how much money it keeps after paying its core costs — down to 40.6 percent from 46.5 percent the quarter before. Chief Financial Officer Bob Komin explained this on a call with investors after the earnings report. Despite the drop, he said the company plans to grow its manufacturing capacity by more than ten times this year.

Cerebras actually has some advantages when it comes to getting the materials it needs to make chips. Because it builds its memory directly onto the chip itself, it is less affected by the rising cost of a special type of memory called HBM, or high-bandwidth memory. CEO Andrew Feldman pointed out that Nvidia has been hit hard by those rising memory costs. He believes this gives Cerebras a real chance to win more customers.

Cerebras also uses a chip-making process from TSMC that is slightly less cutting-edge than what Nvidia and AMD use, which means there is less competition for that type of manufacturing. In other words, Cerebras can get its chips made more easily than some of its bigger rivals. This is important because the whole AI chip industry is facing production shortages. Having more reliable access to chip production could help Cerebras grow faster.

Despite the stock drop, Cerebras raised its forecasts for the rest of the year. It now expects its adjusted revenue for 2026 to be between $880 million and $890 million, up from its earlier estimate. The company's finance chief also said Cerebras plans to more than triple its revenue in 2027. These are bold goals, and meeting them will be key to convincing investors that the company is worth its high stock price.
