Business

Know the Business — Nebius Group N.V.

Nebius is a capital-intensive, customer-financed AI infrastructure utility-in-the-making wrapped inside a Dutch holding company that also owns an autonomous-vehicle business (Avride), an edtech (TripleTen), and minority stakes in two software companies (ClickHouse, Toloka). The economic engine is the core AI Cloud — 98% of Q1 2026 revenue, the only segment generating positive Adjusted EBITDA, and the recipient of more than $20 billion of planned 2026 capex. The market is most likely overestimating how much of the long-dated $46 billion contracted backlog will translate cleanly into equity value, and underestimating the embedded option value in two assets that do not appear on the income statement: the ClickHouse stake (remeasured to ~$1.6B in Q1 2026) and the owned-power optionality in two US gigawatt sites.

1. How This Business Actually Works

Nebius rents GPU compute to AI customers — but the real engine is the conversion of customer cash, debt, and equity into power, GPUs, and data-center concrete, then into multi-year revenue contracts that earn a depreciation-plus-spread. This is a utility-style buildout disguised as a software business. In Q1 2026 the company spent $2.5B of capex against $399M of revenue — a 6.2x capex-to-revenue ratio — and pulled in $2.3B of operating cash flow almost entirely from a $3.2B build-up in deferred revenue (customers prepaid for capacity not yet delivered). The business in one sentence: customers prepay, NBIS builds, depreciation begins, and the spread accretes for 4–5 years.

The unit economics that matter are utilization and contract tenor, not headline gross margin. The Nebius core segment hit a 45% Adjusted EBITDA margin in Q1 2026 against an industry expectation of 20-30% in steady state — but Adj. EBITDA strips out the $212M of quarterly D&A that is the cash cost of GPU depreciation already incurred. GAAP operating loss was $128M in Q1 2026 because depreciation on a 4–5 year useful life now flows through faster than ramp-stage revenue can absorb it. The math only works if utilization stays high through the depreciation window — which is why the Microsoft and Meta reserved-capacity contracts are the core financing instrument, not just revenue.

The leverage is operating leverage on a fixed base, not pricing leverage. SG&A and product development moved from 192% of revenue to 53% in twelve months because revenue scaled, not because absolute spend fell. The same dynamic reverses if utilization falls before the next capex wave is fully ramped.

2. The Playing Field

The peer set is a barbell: one hyperscaler (Oracle), one direct-comparable specialized AI cloud (CoreWeave), and three power-led infrastructure pivot stories (IREN, Applied Digital, Hut 8). Nebius sits closest to CoreWeave on product depth and customer profile, but is materially smaller and trades at a higher EV/Revenue multiple because the market is valuing forward ARR — not LTM revenue — on a base that grew 684% in Q1 2026.

Three things the peer set reveals. First, Nebius is being valued on its forward run-rate, not its trailing print: $51.8B EV against $530M of FY2025 revenue (98x) compresses to roughly 27x against $1.92B Q1-exit ARR — still richer than CoreWeave (18.5x EV/LTM revenue) but no longer in a different universe. Second, the BTC-pivot peers (IREN, APLD, HUT) are real participants on power and capex but have not yet built the software layer that lets a neocloud earn software-like gross margins; APLD's 30% gross margin is the warning sign. Third, Oracle is the only peer with a positive operating income at scale — the model for what a neocloud's economics could look like at maturity, but only if the software layer holds margins when the GPU shortage breaks.

What "good" looks like in this industry is a combination CoreWeave does not yet have and Oracle is too diversified to demonstrate cleanly: owned power, vertical hardware integration, and software margin on top of compute. Nebius is the only peer in the set that explicitly claims all three. Whether that translates into durable returns on the $20-25B of 2026 capex is the central investment question.

3. Is This Business Cyclical?

It is, but the cycle has not happened yet. AI cloud has been in a single-direction up-cycle since 2023 — H100 spot prices rose 40% in the six months to April 2026 — and Nebius has only ever operated in a shortage. The cycle will hit four places at once when supply catches up: GPU rental price, utilization, contract tenor at renewal, and ABS / convertible market terms that fund the next capex wave. The historical templates are the 2001–2002 telecom-fiber bust and the 2022–2023 crypto-mining unwind: oversupply, prices falling faster than depreciation schedules, and operators carrying long-dated debt against assets that depreciate in 4–5 years.

Capex precedes revenue by roughly 18 months, and the gap currently sits at ~7x. If demand falters before the 2026 capex base rolls into the rate base, the operating leverage that produced 32% Adj EBITDA margins in Q1 2026 reverses sharply because depreciation is locked in but revenue is not. The first leading indicator of a turn would be shorter contract tenors at renewal — the day a hyperscaler signs a 12-month deal where it used to sign 5-year, the equity multiple compresses regardless of GAAP earnings.

4. The Metrics That Actually Matter

The five metrics below determine whether the equity compounds or impairs.

NBIS is the only peer that scores strongly on all five of the metrics that determine durable returns in this industry. CoreWeave matches it on ARR and contracted power but is materially levered. The BTC-pivot peers match on owned capacity but have no software layer. Oracle has all of these in spades but at a scale where AI cloud is a sub-segment of a much larger business.

5. What Is This Business Worth?

Value here is determined by two things in tension: the run-rate cash flow that the AI cloud build will produce when 4 GW of contracted power is fully ramped, discounted by the financing cost of getting there, and the carry value of two non-operating assets (ClickHouse stake, Avride) that consolidated metrics hide. A clean DCF on the AI cloud alone is premature — the depreciation curve, utilization assumption, and terminal multiple all swing the answer by an order of magnitude. The right framing is sum-of-the-parts, because the consolidated income statement mixes a build-phase utility, two cash-burning pre-revenue businesses, and two minority software stakes that are not priced in operating cash flow.

The investment math tilts on the Nebius core. ClickHouse contributes maybe $5-7 per share at the current carry; Avride and TripleTen are option-value rather than valuation drivers; net cash is earmarked. Roughly 80-90% of the $52B equity market cap is the present value of the AI cloud business — and that value is mostly forward-looking. At $52B EV against $1.92B Q1-exit ARR, the market is paying ~27x ARR for an asset that mgmt expects to grow to $7-9B by year-end. The valuation works if ARR compounds at the guided rate without margin compression and if the next $20B of capex earns returns above its financing cost; it breaks if either condition fails. The margin of safety is in the contracted backlog, not the multiple.

6. What I'd Tell a Young Analyst

Stop modeling this as a software company. The right mental model is a regulated utility in mid-buildout, with the twist that revenue is locked in by reserved-capacity contracts before the asset is built — so customer prepay is the cheapest financing in the business and the most important number on the cash flow statement. Watch four things in order. First, contracted power additions each quarter — they are the cleanest leading indicator of forward revenue, more reliable than ARR which lags. Second, contract tenor at renewal — when a hyperscaler signs a shorter deal than the prior one, the cycle has turned. Third, the spread between depreciation expense and revenue per MW — the silent killer if utilization slips. Fourth, the ClickHouse mark — the only piece of equity value that does not depend on the AI cloud build going right.

The market is most likely wrong right now to treat consolidated revenue and consolidated EBITDA as the right denominators. Almost all the EBITDA is the Nebius segment (45% margin in Q1 2026), almost all the loss is Avride and TripleTen, and almost all the future depreciation is GPUs already on the balance sheet. If you mix them you will under-value the core and miss the optionality in the stakes. If you are in this name, you are underwriting execution on power, GPU allocation, and the financing stack — not TAM and not a software multiple. The thesis breaks the day a Microsoft or Meta contract is renegotiated, or the day spot GPU prices roll over before the next capex tranche is in the rate base.
