Explosive Revenue Growth
Group revenue grew 684% year-over-year to $399 million in Q1 and was up 75% sequentially. Nebius AI (excl. consolidated investments) revenue rose 841% YoY to $390 million, an 82% quarter-over-quarter increase and represented 98% of group revenue.
Strong EBITDA and Margin Expansion
Group adjusted EBITDA reached $130 million (vs $15 million last quarter and a loss of $54 million a year ago) with a group adjusted EBITDA margin of 32%. Nebius AI adjusted EBITDA margin expanded to 45% from 24% in Q4 (nearly doubling quarter-over-quarter).
Improved Run-Rate and Reiterated Guidance
Nebius AI annualized run-rate revenue reached $1.9 billion at quarter end, up over 50% from $1.25 billion in the prior quarter. Management reiterated full-year targets: ARR $7–9 billion, group revenue $3.0–3.4 billion and group adjusted EBITDA margin around 40%.
Robust Balance Sheet and Liquidity
Cash and equivalents were $9.3 billion at quarter end. The company raised more than $6 billion year-to-date (including ~$4.3 billion in convertible note proceeds and a $2 billion NVIDIA equity investment) and generated $2.3 billion of operating cash flow in Q1 versus an operating cash outflow of $198 million a year earlier; customer prepayments reached a new quarterly record.
Rapid Capacity Contracting and Owned Footprint Growth
Contracted power exceeded 3.5 gigawatts and management is targeting at least 4 gigawatts this year. Owned contracted capacity now accounts for more than 75% of total power; a new Pennsylvania site was announced supporting up to 1.2 gigawatts once fully live.
Transformative Meta Agreement
Signed a 5-year $27 billion agreement with Meta comprised of $12 billion of dedicated capacity plus a $15 billion optional allocation that Nebius can either allocate to Meta or sell to its AI cloud customers — an arrangement management says can unlock asset-backed financing and improve margin and visibility.
Product, Partnership and M&A Momentum
Launched Aether 3.5 and completed three strategic acquisitions (Tavily, Eigen AI, Clarifai) that strengthen inference and agentic capabilities; Eigen was noted as NVIDIA-recognized #1 speed inference provider. Expanded NVIDIA partnership and achieved NVIDIA Exemplar Cloud status on GB300 across multiple GPU generations.
Demand, Pricing and Pipeline Momentum
Demand remained strong with several customers competing for each GPU (management cites 4+ customers per GPU). Pipeline for the AI cloud grew 3.5x quarter-over-quarter; management reported pricing gains, longer average contract durations, higher contract values and expanding prepayments.
