Key Takeaways
- Cerebras delivered Q2 core revenue of $210 million, surpassing analyst expectations of $191 million and representing a 100% year-over-year increase.
- Shares tumbled 17% in extended trading following a 12% gain during the regular session.
- The company’s adjusted operating loss of $34 million significantly outperformed Wall Street’s projection of a $63 million deficit.
- Management increased its fiscal 2026 core revenue target to $890 million and elevated gross margin projections to 41%-43%.
- The company’s backlog remained stable at approximately $25 billion, anchored by a substantial multi-year cloud agreement with OpenAI.
Cerebras Systems delivered a solid quarterly performance on Wednesday, yet investors responded with disappointment. Shares plummeted roughly 17% in after-hours activity to approximately $219, erasing gains from a 12% rally during normal trading hours.
The company’s core revenue reached $210 million for the quarter, exceeding the $191 million consensus estimate and marking a twofold increase from the prior-year period.
Cerebras employs an adjusted revenue framework. The metric excludes pass-through revenue that generates zero margin while incorporating warrant amortization expenses. For Q2, traditional reported revenue stood at $180.1 million, which adjusted to $210 million using the core revenue methodology.
The company now anticipates full-year adjusted operating margin of approximately -18%, a notable improvement from the -30% projection issued in June.
This represents meaningful progress. During the Q1 earnings report in June, management guided toward an adjusted operating margin of -30%. The revised -18% target demonstrates the business is narrowing losses more rapidly than anticipated.
Third-quarter projections similarly exceeded analyst estimates. Wall Street already anticipates Cerebras will achieve adjusted operating profitability by 2027, and the current trajectory indicates this milestone could arrive as planned or potentially sooner.
The bottom line presented a more troubling picture. Cerebras recorded a net loss of $450.5 million in Q2, a sharp reversal from net income of $309.5 million during the comparable quarter last year.
The company’s backlog held at roughly $25 billion. For a rapidly expanding enterprise, market participants typically expect this metric to demonstrate upward momentum.
OpenAI Partnership Forms Backlog Foundation
A substantial portion of that backlog stems from a multi-year agreement with OpenAI for cloud-based server rentals. OpenAI maintains expansion rights within the deal and receives equity warrants as part of the partnership terms.
Cerebras has secured additional partnerships with Amazon and AMD. These arrangements enable Cerebras’ WSE chip to operate in conjunction with Amazon and AMD processors for accelerated inference workloads. Amazon is similarly receiving equity warrants.
Shares Experience Significant Swings Since Debut
Cerebras debuted publicly in May with an IPO price of $185 per share. The stock opened at $350 on day one and peaked at $386, before retreating to a low of $161 by late June.
The stock has subsequently oscillated between $162 and $266. It has experienced price movements exceeding 3% in either direction on 43 of its 62 public trading days.
The company currently commands a market capitalization of approximately $59.37 billion.
Cerebras elevated its full-year core revenue guidance from $880 million to $890 million, while improving its gross margin forecast to a band of 41% to 43%.
