Nebius increased 2025 revenue to $529.8 million while investing $4.07 billion in AI cloud infrastructure. Growth is clear, but the model still requires heavy investment, depreciation and external financing. The current 53/100 Vestorvia score has only 7% data coverage, so it is a provisional result that exposes a data limitation rather than a definitive assessment of financial quality.
What does Nebius do?
As of the review date, Nebius Group's primary business is a full-stack AI cloud platform offering GPU compute, storage, networking and managed software tools for model training and inference. The Group also consolidates Avride, which develops autonomous vehicles and delivery robots, and technology education provider TripleTen, while holding significant minority stakes in ClickHouse and Toloka.
The revenue model combines pay-as-you-go use with fixed reserved-capacity contracts. Customer advances can support cash flow before the related service is recognised as revenue, so cash receipts, accounting revenue and profitability must be read separately.
How is the revenue model distributed?
FY 2025 consolidated revenue increased from $91.5 million to $529.8 million. Nebius AI cloud revenue rose from $68.3 million to $480.3 million and drove most of the increase. The remainder came mainly from TripleTen, while Avride's contribution remained limited. The Group's economics are therefore increasingly tied to AI cloud capacity utilisation and pricing.
Later information is kept separate: Q1 2026 total revenue was $399.0 million, including $389.7 million from Nebius AI cloud. The company attributed the increase to capacity scaling, pricing and utilisation. This interim period shows current scale; it is not used retrospectively as a cause of FY 2025 results.
Why is the Vestorvia Financial Score 53?
Growth 50/100: Official tables show 479% consolidated revenue growth and 603% AI cloud growth in 2025. However, the complex 2024 divestment and restructuring prevent a clean standard five-year comparison. The Vestorvia pipeline could not establish a sufficient historical series and therefore assigned neutral scores. A score of 50 does not imply weak reported growth.
Profitability 50/100: Subtracting $166.2 million of cost of revenue from revenue produces about $363.6 million of gross profit and a 68.6% gross margin. Product development of $177.3 million, sales, general and administrative expense of $378.5 million, and depreciation of $404.0 million led to an operating loss of about $596.2 million. The neutral score reflects tag coverage; the statements show positive gross economics but a loss after the full operating cost base.
Cash flow 50/100: Operating activities provided $401.9 million, including an important contribution from $982.5 million of strategic customer advances. Purchases of property and equipment were $4.07 billion. In simple terms, free cash flow subtracts long-term infrastructure investment from operating cash; that calculation is approximately negative $3.66 billion. Growth therefore required investment far beyond internally generated cash in 2025.
Balance sheet 63/100: Current assets were $4.71 billion, current liabilities $1.53 billion and cash $3.68 billion, producing a current ratio near 3.08. Short- and long-term debt was approximately $4.13 billion, with $1.30 billion of non-current deferred revenue. The cash buffer is meaningful, but debt and investment commitments need to be considered with it.
Shareholder policy 50/100: Share-based compensation was $83.2 million, around 15.7% of revenue. Total issued and outstanding shares at year-end were 253.0 million. Capacity expansion was funded through equity, convertible debt and customer advances. The model assigned a neutral score because it lacked a sufficient standard series; the practical question is how growth translates into per-share economics over time.
Strengths and areas to monitor
- AI cloud revenue increased more than sixfold in 2025.
- Calculated gross margin shows a positive contribution after direct service costs.
- Year-end cash of $3.68 billion provides a buffer against current liabilities.
- Q1 2026 showed a material increase in capacity utilisation and revenue scale.
- 2025 capital expenditure was about 7.7 times annual revenue.
- The operating result remained negative after depreciation.
- Customer advances were an important part of operating cash flow.
- Two material weaknesses in internal control over financial reporting were disclosed.
How should the competitive position be read?
Nebius competes for AI infrastructure budgets with large general-purpose cloud providers and specialist GPU cloud operators. Revenue definitions, lease structures and data-centre ownership differ across companies, so this article does not publish an unverified margin or capacity ranking. The verifiable distinction in Nebius's filing is the dominant weight of AI cloud within Group revenue.
Competition is not only about GPU count. Access to power and data centres, timely deployment of new hardware generations, network and storage performance, software tools, pricing, customer concentration and supplier dependence all matter. The 20-F also identifies rapid technological change, hardware supply and winning and retaining major customers as key risks.
What strategic direction has the company disclosed?
Nebius is directing resources toward GPU and data-centre capacity, its in-house hardware and software layer, and a full-stack platform spanning training through production inference. Purchases of property, equipment and intangible assets reached $2.47 billion in Q1 2026. The conversion of this investment pace into revenue, utilisation and operating profitability is the central execution measure for future reports.
These plans describe the company's disclosed strategy; they do not predict commercial outcomes or the share price. Future reviews should consider AI cloud revenue, cost ratio, operating results after depreciation, cash generation excluding customer advances, debt, share-based compensation and capacity utilisation together.

Frequently asked questions
What is Nebius's main revenue source?
Nebius AI cloud generated $480.3 million in FY 2025 and was the main source of the Group's $529.8 million consolidated revenue.
Why was free cash flow negative despite positive operating cash flow?
Operating cash was $401.9 million and benefited from customer advances, while GPU- and data-centre-heavy capital expenditure reached $4.07 billion.
Is the score of 53 a definitive financial-quality result?
No. SEC companyfacts coverage was only 7%, so 14 of 15 measures used neutral scores. It is a provisional model output and should not be used for peer comparison.
Where the figures come from
- Nebius Group 2025 Form 20-F, SEC — audited fiscal year ended 31 December 2025.
- Nebius Group Q1 2026 Form 6-K exhibit, SEC — unaudited interim period ended 31 March 2026.
- The score of 53 comes from Vestorvia's current SEC companyfacts pipeline. Fourteen measures used neutral scores because only one populated; financial commentary therefore relies directly on the 20-F tables and does not overstate score precision.
