Nebius is a genuine AI-infrastructure hypergrowth story: FY2025 revenue jumped +479% to $530M, R&D rose 54% to $177M, and capex exploded +403% to $4.07B as the company races to build GPU/data-center capacity. That is the right end of the secular AI buildout, and the firm is not capital-starved — $3.68B cash and $4.59B equity give it runway to keep spending. Operating cash flow is even positive at $385M. On growth and ambition alone, this is a credible neocloud contender.

The problem is that the economics underneath the growth are not yet a business that earns money. Operating income was -$612M (a -115.5% operating margin), meaning core operations burn well over a dollar for every dollar of revenue. The headline $82.5M of net income and the 15.6% net margin are therefore misleading: with operations losing $612M, reported profit is coming from non-operating items, not the data-center business itself. ROE is just 1.8%. The note on the data: no Risk Factors / MD&A narrative text was actually provided with this request, so I am grounding strictly in the XBRL numbers and not citing filing language I can't see. The revenue history is also discontinuous (FY2021 $4.79B collapsing to ~$10–90M in FY2022–24 reflects the post-spinoff reset), so multi-year trend visibility is genuinely thin — a reason to hold conviction down.
