Nebius just delivered the kind of revenue growth that most companies can only dream of. The market responded by sending the stock down 17%.
On November 12, 2026, Nebius Group (NBIS) reported third-quarter results that showed revenue exploding 571% year-over-year to $980.8 million. Adjusted EBITDA swung to a positive $465.8 million from a loss a year earlier. On paper, this was a spectacular quarter.
Yet the stock closed at $128.64, down 16.84% for the day. At one point in pre-market trading, it had dropped nearly 19%.
This is the paradox of the AI infrastructure trade in late 2026. Growth is not enough. The market wants growth and capital discipline. And Nebius just told investors it needs to spend a lot more money.
The Numbers: Growth Was Real, But So Was the Spending
Nebius is a “neo-cloud” provider that builds AI infrastructure for companies that need computing power for training and deploying models. It competes directly with CoreWeave.
The Q3 report showed:
Revenue: $980.8 million, up 571% year-over-year
Net loss per share: $0.13, much narrower than the $0.50 loss a year earlier
Adjusted EBITDA: $465.8 million, a massive swing from a $5.2 million loss
AI Cloud revenue: $973.8 million, up 643%, accounting for approximately 99% of group revenue
On the surface, this looks like a company firing on all cylinders. Revenue is growing at a pace that would make most Silicon Valley startups jealous.
But then came the guidance.
The Capex Bombshell
Nebius raised its annual capital expenditure outlook from the previous $20–25 billion range to approximately $27 billion. Market expectations had been around $22 billion.
The company also trimmed its full-year 2026 revenue guidance to $3.0–$3.2 billion from the previous range of $3.0–$3.4 billion. The reason: some third-party computing capacity that was expected to come online this year has been delayed to the first half of 2027, particularly at the New Jersey colocation site where temporary power generation was wound down faster than expected.
For 2027, Nebius guided revenue of $12–13 billion—roughly quadruple the 2026 level—but also guided capex of $40–45 billion to add more than 1 GW of computing capacity.
This is the worst combination for an AI infrastructure stock. You are spending more money than expected, and you are generating less revenue than expected in the near term. The market punished the stock accordingly.
Why This Matters Beyond Nebius
Nebius is not the only AI cloud company facing this scrutiny. CoreWeave, its closest competitor, has also seen its stock hammered over debt and capex concerns. The entire AI infrastructure sector is being repriced as investors ask a simple question: How much money needs to be spent before the profits arrive?
The five largest AI spenders poured $230 billion into capex in Q3 2026 alone, more than their combined operating cash flow, pushing their collective free cash flow into negative territory for the first time. Markets are starting to distinguish between AI spending and the revenue that supports it.
Nebius, with a P/E ratio of over 990x based on trailing earnings of $0.10 per share, has no margin for error. Any sign that growth is slowing or costs are rising triggers a violent selloff.
The Bull Case: The Backlog Is Still Massive
The bears are focused on the capex increase and the trimmed guidance. But the bulls have a counterargument: Nebius is still growing at an extraordinary pace, and the demand for AI compute is not going away.
Nebius has a $27 billion deal with Meta referenced in its disclosures, and it maintained a $12–13 billion 2027 revenue outlook. The company also secured $3.5 billion in financing in October through a Citi bridge loan, giving it additional capital to fund its expansion.
Critically, customer prepayments now cover more than 100% of the capital needed for contracted capacity, up from 50–60% in Q2. More than 90% of contract value signed in Q3 included customer prepayments. This significantly reduces Nebius’s reliance on external financing.
Analysts remain largely positive. The consensus rating is Buy (or Moderate Buy), with an average price target ranging from approximately $274 to $297—more than double the current price. Even after the crash, the stock is still up over 43% year-to-date.
What Investors Should Watch
1. Execution on the delayed capacity. If the third-party capacity comes online in early 2027 as promised, the revenue guidance cut is temporary. If it slips again, the stock will face another leg down.
2. The capex-to-revenue ratio. Nebius is spending $27 billion to generate roughly $3 billion in revenue this year. That ratio needs to improve over time for the business model to be sustainable.
3. Prepayment coverage. The fact that prepayments now cover over 100% of capex on new deals is a genuine positive. Watch whether this holds as the company scales.
BS Maurya Research Verdict
Nebius is a high-growth, high-risk AI infrastructure play. The revenue growth is genuine, the prepayment structure is improving, and the 2027 revenue outlook of $12–13 billion is ambitious. But the capex burden is enormous—$40–45 billion in 2027 alone—and the guidance cut is a yellow flag. The stock’s 990x P/E leaves no room for disappointment.
For risk-tolerant investors who believe AI compute demand will remain insatiable, the post-crash price may offer an entry point. For everyone else, this is a reminder that in the AI infrastructure trade, growth alone is not enough. The market is now demanding a path to profitability.
