Shares jumped 4.2% to $141.24 as Nebius Group released Q1 2026 results before the bell today, snapping back from yesterday's $135.51 close in a broader market selloff. Analysts expected a loss of $0.81 per share on revenue of $375.13 million — a substantial sequential jump from Q4's $227.7 million. The question now: whether the company that rents computing power to the biggest names in AI can spend fast enough to capture demand without drowning in cash burn.

A $50 Billion Order Book Sounds Great — Until You See the Bill

Nebius's contracted backlog approaches $50 billion, anchored by deals up to $27 billion with Meta and $19.4 billion with Microsoft. But fulfilling those orders requires an enormous buildout. The company plans to spend $16 billion to $20 billion this year in capital expenditures — spending that is moving faster than its current revenue.

Roughly 60% of that is covered by existing cash, operating cash flow, and commitments , leaving a multi-billion-dollar gap that will likely require new debt or equity sales — diluting current shareholders or adding interest costs.

Revenue Is Surging, but Losses Remain the Norm

Nebius ended 2025 with $1.2 billion in annualized recurring revenue (yearly revenue from ongoing contracts) and Q4 revenue of $228 million, up 547% year over year.

Management guided for $3.0–$3.4 billion in 2026 revenue with an adjusted profit margin (before interest, taxes, and non-cash charges) near 40%. Yet the operating margin sits at -113.3% — meaning the company currently loses $1.13 for every dollar it earns. Investors are betting that scale will flip those numbers, but Q1 guidance updates will be the first real proof point.

The Meta Deal Is Transformative — but Mostly a 2027 Story

Meta signed a deal worth up to $27 billion, including $12 billion of dedicated capacity and up to $15 billion of additional compute over five years. However, delivery begins in early 2027, and Nebius confirmed that its 2026 financial guidance remains unchanged — meaning this quarter's numbers won't yet reflect the deal's economics.

Valuation Leaves No Room for Stumbles

At a price-to-sales ratio of roughly 65x, investors pay $64.73 for every dollar of annual revenue.

Analysts estimate Nebius must deliver about 45% annual revenue growth for eight years to support the current stock price. With revenue misses in three of the last four quarters and $14.7 million in insider selling over the past 90 days , any shortfall today could punish the stock severely in a market already on edge.
