Why did CBRS move on Jun 23, 2026?

Cerebras Systems (CBRS) shares fell over 8% after the bell following its first earnings report since its IPO [13, 17, 21]. Although the company reported Q1 revenue of $193.4 million that beat the $181.4 million estimate [6, 8] and posted a narrower-than-expected EPS loss of -$0.04 (vs. -$0.14 estimated), it reported a GAAP net loss per share of $0.22 [11, 15]. Despite raising its FY2026 core revenue outlook to $855–$865 million [3, 10, 20] and announcing a massive multi-year, $20 billion deal with OpenAI [1, 2, 22], the stock declined as the projected sales outlook ultimately left investors wanting more [25].
