Cerebras CBRS Earnings: CEO Says Margin Forecast Misread

I now have all the data needed. Writing the article.

Lead

Shares of Cerebras Systems (CBRS) plunged more than 17% on June 24, 2026, sliding from a prior close of $226.72 to an intraday low of $185.23, after the semiconductor company's first earnings release as a public company delivered stronger-than-expected revenue and guidance but rattled investors with a pronounced forecast for margin compression. Chief Executive Andrew Feldman appeared on CNBC's Squawk on the Street Wednesday morning to argue the selloff was misplaced: "It is misunderstood. 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."

What Happened

The quarter, however, arrived alongside forward guidance that the market read as a structural deterioration. For Q2 2026, Cerebras projected core gross margin of 36–38%, down sharply from the 47% reported in Q1. The full-year 2026 outlook calls for core revenue of $855–$865 million — 69% year-over-year growth at the midpoint — with core gross margins of 38–41%. Both revenue targets exceeded analyst estimates. The margin range did not.

The Margin Debate

The mechanism behind the compression is structural rather than competitive. Chief Financial Officer Bob Komin told analysts that the rental and self-build costs associated with rapidly scaling capacity would shave 10 to 15 percentage points off gross margins in the near term. The specific trigger is a lease-back arrangement: Cerebras is reclaiming hardware it previously sold to existing clients and rerouting those systems to OpenAI, which has contracted for 750 megawatts of Cerebras semiconductor capacity under a multi-year deal exceeding $20 billion. The company's $25 billion backlog is predominantly that OpenAI contract, with roughly $4 billion expected to convert to revenue over the next two years.

Feldman framed the cost increase as a deliberate choice to absorb near-term margin pressure in exchange for accelerating what is the largest customer commitment in the company's history. "We're trying to move at the speed of AI," he said, "and data centers move with the speed of real estate."

Even at 38–41%, the full-year margin guidance landed above analyst consensus expectations of 29.58%. The context of the selloff is the gap to peers: Nvidia (NVDA) operates at mid-70% gross margins, and Advanced Micro Devices (AMD) runs in the mid-50% range.

Strategic Context

The earnings report underscored the twin risks inherent in Cerebras' position at this stage of its growth: heavy customer concentration and capacity-constrained demand. The top two customers — Abu Dhabi-based G42 and Mohamed bin Zayed University of Artificial Intelligence — accounted for 74% of Q1 revenue. Adding OpenAI brought the top-three figure to 83%. Feldman highlighted that GPT 5.4 is now running on Cerebras processors, and that Amazon Web Services (AMZN) has committed to deploying Cerebras chips in its data centers, with revenue expected within 12 months.

An additional technical overhang weighed on sentiment: the expiration of a lock-up restriction on Thursday would release approximately 28 million Class A shares — roughly 13% of the shares sold in the May IPO — into the open market.

Market Reaction

Several Wall Street firms maintained bullish stances following the results. Morgan Stanley raised its 12-month price target on CBRS to $273 from $250, and Wedbush lifted its target to $280 from $270, reiterating an Outperform rating. TD Cowen noted that "key engagements with OpenAI and AWS are moving forward." The consensus target across eleven covering analysts stands at approximately $294.
