Material Changes vs. Prior Period
- Revenue Surge: Revenue increased 479% year-over-year, driven primarily by the Nebius AI cloud segment, which grew 603% to $480.3 million. This growth was fueled by the deployment of next-generation GPUs and long-term contracts with hyperscalers.
- Profitability Shift: The company moved from a net loss of $352.0 million in 2024 to a net income of $9.8 million in 2025. This turnaround was largely due to the $598.9 million gain on the revaluation of equity securities (ClickHouse), offsetting a significant operating loss of $611.7 million.
- Capital Intensity: Capital expenditures surged to $4.07 billion in 2025 (up from $807.5 million in 2024) to fund rapid data center expansion and GPU procurement.
- Debt Financing: The company issued approximately $4.16 billion in convertible notes in 2025 (June and September issuances), significantly increasing leverage to fund growth.
- Segment Performance: The Nebius segment achieved positive Adjusted EBITDA of $59.0 million in 2025, reversing a loss of $128.5 million in 2024. Avride and TripleTen remained unprofitable.
Guidance, Outlook, and Risks
Management Commentary and Outlook
- Strategic Contracts: Secured multi-year, multi-billion dollar agreements with Microsoft (up to $17.4 billion) and Meta (up to $27 billion) to provide dedicated GPU capacity. These contracts are critical for future revenue visibility.
- Capacity Expansion: Contracted power capacity exceeded 2 GW as of February 2026, with active power at 170 MW as of year-end. Expansion includes greenfield sites in the US (Missouri, Alabama) and Europe.
- Financing: Raised over $5 billion in 2025 and an additional $6 billion in Q1 2026 through equity and convertible debt to support infrastructure build-out.
Key Risks and Contingencies
- Internal Controls: The company identified two material weaknesses in internal control over financial reporting (fixed assets and revenue recognition for TripleTen). An adverse opinion was issued on internal controls for 2025. Remediation is ongoing, with completion expected by end of 2026.
- Capital Requirements: The business is capital-intensive and currently not profitable on an operating basis. Continued growth depends on the ability to raise additional equity or debt financing.
- Supply Chain & Power: Heavy reliance on a limited number of suppliers (e.g., Nvidia) for GPUs and challenges in securing reliable power and data center sites.
- Geopolitical: Exposure to geopolitical conflicts (e.g., Middle East) and evolving regulatory frameworks regarding AI and data centers.
Investor Verification Checklist
- Revenue Quality: Verify the recognition timing and sustainability of revenue from the Microsoft and Meta contracts, specifically regarding the "reserved capacity" model and potential service credits.
- Internal Control Remediation: Monitor progress on remediation of the two material weaknesses in internal controls to ensure future financial reporting reliability.
- Capital Burn Rate: Assess the runway provided by the $3.7 billion cash balance against the $4+ billion annualized capital expenditure rate and debt service obligations.
- ClickHouse Valuation: Understand the non-recurring nature of the $598.9 million gain from ClickHouse revaluation and its impact on GAAP net income versus operating performance.
- Debt Covenants: Review the terms of the $4.16 billion convertible notes issued in 2025, including conversion triggers, accretion rates, and redemption provisions.
