Cerebras CEO says margin forecast was 'misunderstood' as stock plummets after earnings

Cerebras Systems CEO Andrew Feldman said Wednesday that investors "misunderstood" the artificial intelligence chipmaker's margin guidance, as shares slid 17% after the company reported results for the first time since going public.

Analysts at Mizuho and Wedbush raised their estimates following Cerebras' earnings call. But the company forecasted a narrower gross margin in its core business, excluding impact from customer warrants and data center pass-through revenues. The number was 47% for the first quarter, and it should be between 38% and 41% for the full year.

"It is misunderstood," Feldman said on CNBC's Squawk on the Street. "You know, we laid out a plan at the start of '26. We shared that plan as we went public a few months ago, and we're beating that plan."

He said management made clear that Cerebras will need to rent back some equipment from one of its largest clients.

"I think it's not going to be a straight line," he said.
