Cerebras Systems CEO Andrew Feldman said investors misunderstood the company's margin guidance after shares dropped sharply on Wednesday [1, 2].
The reaction highlights the volatility of AI-focused stocks and the high expectations investors place on profitability metrics for new public companies.
Cerebras Systems (NASDAQ:CBRS) reported its first quarterly earnings since going public in May 2026 [4]. While the company reported a revenue beat, it issued a warning that full-year gross margins would be lower than previously expected [1, 3].
Market reaction was immediate. Reports on the magnitude of the decline varied, with some sources stating shares fell about 14% to roughly $194 per share [1, 2], while other reports indicated the decline exceeded 17% [3].
Feldman addressed the sell-off during an appearance on CNBC’s “Squawk on the Street.” He said that the market misread the company's outlook regarding its profit margins [1, 2].
"Investors misunderstood our margin guidance," Feldman said [1].
The CEO reiterated that the narrative surrounding the forecast was incorrect, saying, "The margin forecast story is misunderstood" [2].
Despite the stock tumble, the company's revenue performance exceeded analyst expectations. However, the warning regarding annual profit margins appeared to outweigh the revenue gains in the eyes of traders [3].
“"Investors misunderstood our margin guidance."”
The sharp decline in CBRS shares demonstrates that for high-growth AI hardware companies, future margin guidance is often more influential than current revenue beats. Because Cerebras recently entered the public market in May 2026, investors are establishing a baseline for its long-term profitability; any perceived dip in that trajectory can trigger significant volatility.
