Nebius Group 2025-26: ARR $7-9B Target, Microsoft + Meta Anchor
FY25 revenue $529.8M (+351%); core AI cloud infra +400% YoY in Q3 alone. Microsoft contract $17.4-19.4B; Meta ~$3B/5yr. Capex $-4.07B FY25 (raised mid-year from $2B → ~$5B). 2026 ARR guide $7-9B. Capacity to 2.5GW contracted by year-end 2026 (vs 1GW prior).
Key takeaways
- Hypergrowth arrived. Revenue $529.8M (+351% YoY from $117.5M FY24). Q4 alone printed $227.7M — i.e. Q4 ran at $911M annualized. Q3 core infra +400% YoY, +40% sequential. The growth curve is real, and it's accelerating.
- Microsoft + Meta = anchor backlog. The Microsoft contract ($17.4-19.4B over multi-year) and Meta deal (~$3B over 5 years) take Nebius from "interesting AI cloud entrant" to "credibly contracted hyperscale-tier capacity buyer." Tranches deploy through 2026.
- 2026 ARR guide $7-9B. That's a 13-17x step up from the Q3 exit core ARR of $551M. Even at the low end, this would put NBIS in the same revenue universe as legacy enterprise SaaS players within 12 months.
- Capacity build-out is enormous. Contracted capacity raised to 2.5GW by year-end 2026 (vs 1GW prior). 800MW-1GW power connected to data centers by end-2026. Capex jumped from initial $2B FY25 plan → ~$5B actual.
- Op income still deeply negative ($-596M FY25), net income flipped positive ($+102M). The positive NI is non-cash / equity-stake monetization driven (Toloka, ClickHouse, Avride non-core stakes monetized). Operating loss reflects scale-up phase. Mgmt expects core infra adj EBITDA positive (already achieved Q2/Q3 ahead of plan).
Business
Nebius Group is the post-Yandex spinoff that re-emerged in October 2024 as the first publicly-traded AI-specialized neocloud. Five business lines, with one dominant:
- Core AI Cloud Infrastructure (~90% of revenue). GPU compute capacity (NVIDIA Hopper + Blackwell), Slurm-based cluster orchestration, AI-native storage, MLflow / JupyterLab / inference platform. The strategic centerpiece. Customers: Microsoft, Meta, Cloudflare, Prosus, Shopify, hundreds of AI-native startups. Q3 ARR exited at $551M.
- Avride (autonomous mobility). Robots + autonomous delivery contracts with Uber, Grubhub. Certified in Japan. Stake monetization candidate.
- Toloka (data labeling for GenAI). FY24 revenue +140%; serves leading AI labs; transitioned to platform for complex GenAI training data tasks. Stake monetization candidate.
- TripleTen (edtech / coding bootcamp). Doubled new student additions YoY in 2024. US market leader in IT bootcamps.
- ClickHouse stake (open-source analytics database). Held as non-core equity stake; ClickHouse a separate public company candidate. Stake monetization candidate.
The strategic narrative is clear: core AI cloud infra is the future of Nebius; non-core stakes (Toloka, ClickHouse, Avride, TripleTen) are funding sources to be monetized as core scales.
Product side: Cloud platform v3.0 ("Ether") + Nebius Talking Factory (inference) launched in 2025. Differentiation strategy is software/services on top of GPU compute — not just IaaS-level capacity rental.
FY25 financial performance
| Metric (FY) | 2023 | 2024 | 2025 |
|---|---|---|---|
| Revenue ($M) | 21 | 118 | 530 |
| Revenue YoY | n/a | +462% | +351% |
| Gross profit ($M) | -11 | 44 | 364 |
| Op income ($M) | -328 | -441 | -596 |
| Net income ($M) | 241 | -641 | 102 |
| Diluted EPS ($) | 0.65 | -2.28 | 0.11 |
| FCF ($M) | 746 | -562 | -3,681 |
| Capex ($M) | -83 | -808 | -4,066 |
| Total debt ($B) | 0.58 | 0.05 | 4.89 |
Q4 stand-alone print: revenue $227.7M (+501% YoY from $37.9M Q4 FY24; +56% sequential); Q4 op income $-235M; Q4 capex $-2.06B (peak build quarter).
Two reads on the financials:
- Revenue compounding is the dominant signal. $21M → $118M → $530M is what 4-5x annual compounding looks like. The ARR exit ($551M end-Q3) and FY26 ARR guide ($7-9B) imply the curve still has another full doubling in it.
- Capital intensity is enormous and rising. Capex stepped up from $-808M FY24 → $-4.07B FY25 (~5x). Net debt swung from net cash to $4.89B gross debt position. This is the cost of buying GPU capacity to deliver Microsoft + Meta tranches.
Net income $+102M FY25 is non-operating — driven by gains on stake fair-value adjustments, non-core asset monetization, and FX. Operating loss of $-596M is the cleaner profitability signal during scale-up phase. Mgmt has guided core infra adj EBITDA positive (achieved Q2/Q3 already; ahead of plan).
Capital allocation
- Capex: $-4.07B FY25 (+403% YoY). Capex guide raised mid-year from $2B → ~$5B. Q4 alone was $-2.06B. Capacity build is the entire capital story.
- Debt: $4.89B total (vs $50M FY24 — i.e. balance-sheet recapitalization). Funded the GPU capacity ramp.
- Equity raised: $700M Dec 2024 offering (oversubscribed). Plus $4B+ in capital raised across 2025 (per Q2 call).
- Non-core stakes: Toloka, ClickHouse, Avride, TripleTen all flagged as potential monetization sources to fund core capex.
- No dividends, no buybacks: All capital deployed into capacity. Standard for hyper-growth phase.
The cap stack moved meaningfully — Nebius has effectively shifted from a self-funded growth story to a debt + equity hybrid funding capacity. That's a structural change vs FY24 and worth tracking through FY26.
FY26 outlook (per Q3 2025 call, 2025-11-11)
| FY26 framework | Detail |
|---|---|
| ARR (end of 2026) | $7B to $9B |
| Contracted capacity | 2.5 GW by year-end 2026 (vs 1 GW prior) |
| Power to data centers | 800 MW – 1 GW connected by end-2026 |
| Microsoft revenue | Tranches in 2026; >50% in 2H |
| Meta revenue | Mostly at full run-rate by 2026 |
| Capex FY26 | TBD, but step up implied to support 2.5 GW |
The $7-9B ARR exit guide is the load-bearing number. Q3 exit ARR was $551M; getting to even $7B by end of 2026 implies ~13x ARR step-up in 14 months. That's only feasible because Microsoft and Meta tranches deliver capacity-paid revenue at scale rather than incremental SMB onboarding.
Mid-term guide: revenue mid-single-digit billions; EBIT margins 20-30% at maturity. The path-to-profit math: at $7-9B ARR and 25% mature EBIT margins, this is a $2B+ operating income business once capex normalizes.
Key risks
- Concentration. Microsoft + Meta are dominant revenue contributors going into FY26. Loss/renegotiation of either contract resets the trajectory materially.
- Capex execution. $4-5B/year capex with 2.5GW contracted capacity assumes timely GPU delivery, data center build, and power interconnect. Any delay pushes Microsoft/Meta tranche revenue right.
- GPU pricing / hyperscaler competition. Microsoft, Google, AWS, Oracle all building AI infra at scale. Nebius's neocloud thesis (better software, dedicated AI focus, lower friction) faces ongoing pressure from cap-rich hyperscalers offering price.
- Capital structure leverage. Total debt $4.89B vs operating losses creates funding-cycle risk if capital markets close. Non-core stake monetization is the planned offset but timing is uncertain.
- Revenue recognition / GAAP volatility. Long-term hyperscale contracts (MS, Meta) introduce timing-of-revenue questions; ARR may diverge from recognized revenue.
- Yandex legacy / geopolitical. Even post-spinoff, residual perception/regulatory issues from Russian origins remain a soft factor for some customer/investor pools.
Bottom line
Nebius FY25 is the inflection-year print: revenue +351%, anchor contracts (Microsoft, Meta) signed, capex stepped to $-4B, contracted capacity doubled to 2.5GW. The FY26 ARR guide ($7-9B) implies a 13-17x step from Q3 exit core ARR. If Microsoft and Meta tranches land on schedule, NBIS exits 2026 as a multi-billion-revenue AI cloud. The risks are concentration (MS/Meta), capex execution, and hyperscaler competition — none of which are obviously fatal at current scale, but all of which gate the $7-9B ARR outcome. This is the highest-beta name in the AI infra category and trades accordingly.
