Executive Summary

Cheaper, but the two biggest questions are still open

Cerebras has fallen to $149, below its $185 IPO price and 61% off its May high. The business is still growing fast: core revenue rose 103% to $210M in Q2, full-year core guidance was raised to $880–890M, and the company holds $25.4B of remaining performance obligations and $6.74B of cash. Against that, GAAP revenue of $180M missed, GAAP gross margin fell to 14% (core 40.6%, guided 38–40% for Q3), and a SemiAnalysis report that OpenAI will run GPT-6.1's Ultrafast mode on Nvidia hits the one customer the backlog depends on. Roughly 171M shares come out of lock-up by mid-November. At about 10x 2027 EV/sales the valuation is no longer stretched, but we would wait for the Q3 print and the lock-up to clear before adding. HOLD, $175 target.

Analysts are near-unanimous Buy (85), but GAAP losses and low margins give little FCF visibility (20); the next two catalysts are lock-up supply and a Q3 print guided to the margin low (45); valuation is no longer stretched but rests on one customer (45); insider sales into weakness weigh on management (50). Weighted 51: Medium.

Risk Heatmap

Quantified Risk Assessment

Severity Risk Factor Prob. PT Impact

High OpenAI concentration

Most of the $25.4B RPO is the 750MW OpenAI deal. A SemiAnalysis report says GPT-6.1's Ultrafast mode will run on Nvidia; if more workloads follow, the backlog and 2027 revenue both shrink.

40% −35%

High Lock-up supply

Up to ~171M shares become saleable by ~Nov 10 against a 34.5M-share IPO float; CEO and CTO have already sold over $240M.

70% −15%

Medium Gross margin

GAAP gross margin fell to 14% in Q2 and core to 40.6%, from renting third-party data-centre capacity. Q3 guide 38–40% is called the low; a further slip would undercut the 60% long-term target.

45% −15%

Medium Nvidia and in-house silicon

Nvidia (including its Groq-based LPU product) and hyperscaler chips compete directly for fast inference.

40% −20%

Medium UAE customer and geopolitics

G42 and MBZUAI were ~86% of 2025 revenue; export-control or CFIUS scrutiny remains possible.

25% −10%

Low Stock-based compensation

~$387M of stock comp in Q2 alone; dilution continues as RSUs vest after the IPO.
