Cerebras Jumps 13-17% After Hours on Q3 Beat and Raised Guide

Cerebras (CBRS) closed Thursday at $97.75, down 3.29 percent, then surged 13 to 17 percent after hours to roughly $110–$115 after its third-quarter results beat on core revenue and management raised its full-year outlook. It's the first post-IPO report the market has rewarded — and the numbers explain why.

Core revenue came in at $230.9 million against a $214.7 million consensus (LSEG via CNBC), comfortably above the $214–$216 million range the company guided in August. The full-year 2026 core revenue guide moved up to $940–$960 million from $880–$890 million, and Q4 was guided to $310–$330 million — at least 34 percent above Q3.

What did Cerebras actually report?

The quarter split into two businesses heading in opposite directions. Cloud and other services revenue rose 265 percent year on year to $141.93 million, now roughly two thirds of GAAP revenue. Hardware revenue fell to $68.88 million from $96.79 million a year earlier. Cerebras is shifting from selling systems to selling compute.

The GAAP picture is uglier. Revenue of $210.8 million, up 55 percent annually, came in slightly under the ~$215 million consensus. The GAAP loss of 67 cents a share was far wider than the expected 14-cent loss, driven mostly by non-cash charges: stock-based compensation hit $541 million in the first nine months of 2026 and pushed the quarter's GAAP operating loss to $224 million. Adjusted EPS landed at 12 to 13 cents depending on the source. Core gross margin of 41.0 percent beat the 38–40 percent guide, and management had flagged Q3 as the margin low point.

Why did the stock jump?

Guidance did the work. The low end of the full-year range rose $60 million and the top $70 million. Management also repeated that revenue should roughly triple in 2027 and named Microsoft as a new customer, with a deal signed in October and first revenue expected in Q1 2027 (CNBC). Terms weren't disclosed. Customer concentration in OpenAI has been the stock's main worry; a second hyperscaler goes straight at it.

The contrast with earlier reports is stark. The stock fell 19.6 percent after Q1 and 11.85 percent after Q2 (TipRanks), and options had priced a 12–14 percent move into this print. The after-hours action matched that band, in the right direction. CNBC measured the gain at about 13 percent, GuruFocus at 13.63 percent, and Reuters via MarketScreener at roughly 17 percent; KuCoin quoted $114.60.

The backdrop didn't help. Nvidia announced Thursday that Jensen Huang had resigned as CEO, and AI hardware stocks slid; Cerebras fell 3.29 percent in regular trading before the numbers dropped.

Where does the stock stand now?

Cerebras listed at $185 on 14 May and hit a 52-week low of $77.84 on 5 November; it closed at $109.18 on 30 October, roughly where the after-hours range puts it now. Even at $115, it sits about 38 percent below the IPO price.

The 180-day lock-up expired on 10 November, so early holders can sell into strength. Analysts cut targets before the print: Morgan Stanley to $178 from $279, Wedbush to $190 from $290, UBS to $250 from $330. StockAnalysis puts the average 12-month target at $245.18, in a $170–$325 range. No post-results revisions had landed at the time of writing.

What are the reference levels?

• Bear, $98: Thursday's close — the after-hours gain fades on lock-up selling and Nvidia nerves.
• Base, $108–$118: the stock opens near after-hours levels and holds into the weekend.
• Bull, $125: analysts raise targets on the guide and the Microsoft deal; about 28 percent above Thursday's close, yet still 30 percent below Morgan Stanley's $178, the lowest cited target.
