Shares of Nebius Group jumped 18.1% to $10.50 on June 1, extending a rally that has lifted the stock more than 31% in a week — with no fresh catalyst beyond the afterglow of blockbuster Q1 results reported on May 13. The move signals investors are still digesting the sheer velocity of Nebius's transformation from a $51 million-a-quarter business into a credible AI infrastructure player, but the price action also raises a basic question: how much good news is already baked in?

  • Revenue Grew Nearly Eightfold, and the Market Is Still Catching Up. Revenue hit $399 million, up 684% year-over-year, beating the Street consensus of $391.6 million.

The AI cloud unit's adjusted EBITDA margin (a measure of cash profitability before interest and taxes) nearly doubled quarter-over-quarter to 45%. Those numbers explain why the stock cratered earlier in May — it had gotten ahead of itself — and is now snapping back as fundamentals reassert control.

  • Mega-Contracts Give Visibility, but Lock In Massive Spending. Nebius signed a long-term deal with Meta to provide up to $27 billion worth of computing capacity over five years.

NVIDIA invested $2 billion in Nebius, a vote of confidence from the dominant chip supplier. Yet management raised 2026 capital expenditure guidance to $20–$25 billion, up from $16–$20 billion, to fund capacity that won't generate revenue until the first half of 2027. That's a staggering spending pace for a company generating $399 million in quarterly revenue.

  • The Cash Pile Is Large but Borrowed. Nebius ended Q1 with $9.3 billion in cash, up from $3.7 billion, mainly from issuing $4.3 billion in convertible notes and $2 billion in prefunded warrants.

Non-current debt more than doubled to $8.4 billion. In plain terms, the war chest is real, but it's largely debt, not profit — and the interest bill is already $64 million a quarter.

  • Execution Beats Expectation, but the Bar Rises Steeply. Management reiterated full-year targets: annualized recurring revenue of $7–$9 billion, group revenue of $3.0–$3.4 billion, and an EBITDA margin around 40%.

Analysts have flagged heavy capital spending as a major concern, noting it puts pressure on margins despite strong revenue growth. The stock's rebound rewards momentum, but sustaining it requires Nebius to convert contracted backlog into real cash faster than its debt service grows.
