# Cerebras needs a $269 million Q4 to hold its $880 million 2026 guide

> The Q3 guide implies 2.4% growth and a wider core loss, and holding the $880–890M year takes a 25% jump in Q4. Tonight's 5 p.m. ET call, the first print since the lock-up opened, decides whether the funds that bought in June or the shorts are right.

[Cerebras Systems](https://theinference.org/markets/companies/cerebras-systems) (Nasdaq: CBRS), the wafer-scale AI chipmaker, reports [third-quarter results](https://investors.cerebras.ai/news-events/news-releases) after the US close tonight, November 12, with the call at 5 p.m [1]. ET [1]. The stock goes in at $93.66, down 3.1% on Tuesday after [Morgan Stanley](https://theinference.org/markets/companies/morgan-stanley) cut its target to $178 from $279 while keeping an Overweight rating, and about 49% below [the $185 price of its May 14 listing](https://theinference.org/article/td-cowen-cerebras-own-underwriter-now-marks-the-stock-below-its-ipo-price) [2].

The main lock-up ended on November 9 with up to 171.1 million shares in play over the full release schedule, [a schedule The Inference laid out this week](https://theinference.org/article/insiders-sold-387-7-million-of-cerebras-stock-19-4-million-more-shares-unlock-wednesday), and the stock has already touched a 52-week low of $77.84 [2]. Around it, [Nvidia](https://theinference.org/markets/companies/nvidia) fell more than 7% overnight on reports about chief executive [Jensen Huang](https://theinference.org/markets/people/jensen-huang), and traders are treating Cerebras as the sector's demand tell before Nvidia reports on November 17 [3].

## The guide back-loads the year

The company pointed Q3 core revenue, its non-GAAP measure, at $214–216 million, just 2.4% above Q2's $209.9 million, with core gross margin of 38–40% against 40.6% in Q2 and a core operating loss widening to about $51.6 million from $33.6 million [4]. Margin is the number that has bitten before: the stock fell 14% in June on a full-year margin forecast [2].

The data vendors cannot even agree on consensus. Zacks carries revenue of $215.8 million and a 13-cent loss, while Koyfin, quoted by [Stocktwits](https://stocktwits.com/news-articles/markets/equity/nvda-fallout-pressures-tech-trade-as-investors-turn-to-cerebras-applied-materials-for-chip-demand-cues/cNGzlg3R99l), carries $274.9 million and a 23-cent loss [2][3]. The company's own guide is the anchor, and it leaves the hard part for later. Holding the $880–890 million full-year outlook, raised from $855–865 million in August, takes about $269 million of core revenue in Q4, 25% above the Q3 midpoint [4]. Cerebras has cleared its own bar before: Q2 landed 8.2% above guide [4].

## Ten funds bought in June and are down 58%

Ten funds reported new stakes at June 30 [5]. [Brad Gerstner](https://theinference.org/markets/people/brad-gerstner)'s Altimeter Capital held 7.23 million shares worth $1.60 billion, its second-largest position behind Nvidia; Coatue, Tiger Global and [Cathie Wood](https://theinference.org/markets/people/cathie-wood)'s ARK held about $2.4 billion between them [5]. The stock has fallen 58% since that filing date, and the funds' September 30 filings are due by November 16 [5].

## Insiders sold, and Culper went after the depreciation

Against them sit the sellers. Insiders sold 1,924,452 shares worth about $394.6 million over the past 90 days, per MarketBeat [2], and short seller [Culper Research's October 28 report](https://finance.yahoo.com/markets/stocks/articles/cerebras-sinks-10-short-seller-173139342.html) knocked the stock down 10% [6]. Culper's sharpest point comes from Cerebras's own paperwork: system useful lives went from 1.5–3 years in late-2025 draft IPO filings to 3–5 years four months later, unexplained, and longer lives mean lower depreciation and fatter margins [6]. A widely shared post puts short interest at 21.33 million shares, 20.62% of the float; no exchange print in hand confirms that figure [7].

## Backlog bigger than the company

The bull case sits in [the filings](https://trendandticker.com/markets/semiconductors/cerebras-cbrs-q3-preview-fourth-quarter-guide-math): $25.4 billion of remaining performance obligations, contracted revenue not yet recognized, at June 30, against a $22.25 billion market value, plus $8.6 billion of cash and short-term investments [4][5]. The load-bearing customer is [OpenAI](https://theinference.org/markets/companies/openai), contracted for 750 megawatts of inference capacity through 2028 in a deal worth more than $20 billion and backed by a $1.0 billion working-capital loan [5][8]. Cash settled the survival question months ago; tonight is about conversion speed.

Analyst targets have barely moved: a $266 mean with a $170 floor, while the stock lost two-thirds of its value, which says the targets price 2027, when consensus expects $2.96 billion of revenue [5].

## Four lines to watch

Core gross margin against the 38–40% guide, where the depreciation question also lives [4][6]. The full-year floor, held or raised [4]. The backlog update, the cleanest read on OpenAI converting [4]. And whether chief financial officer Bob Komin repeats the plan to more than triple revenue in 2027 [5]. Reference levels after the print run about $110 up and $78 down, near 17% either way [2]. Then the ledger closes: 13F filings on November 16, Nvidia on the 17th [2].

## Takeaway

Holding the $880–890 million 2026 guide takes about $269 million of core revenue in Q4, 25% above the Q3 midpoint, on a print that also tests the June funds against insiders who sold and Culper's short case.
