Investment Thesis

Emerging full‑stack AI infra leader with a de‑risked path to multi‑billion revenue run‑rate by 2026, anchored by $20B+ in long‑term, investment‑grade hyperscaler contracts (Microsoft, Meta).
Contracted ARR targets of $7–9B in 2026 imply 7–9x growth from the 2025 exit run‑rate, with core AI infrastructure already inflecting to profitability and positioned for 30%+ Adjusted EBITDA margins as scale is realized.
Current valuation around ~2.5x 2026E ARR suggests meaningful multiple re‑rating potential as execution de‑risks the capacity build‑out and revenue conversion.

Microsoft: 5‑year, $17.4B agreement (expandable to $19.4B), underpinned by a dedicated GPU data center in Vineland, NJ; revenue ramps from late 2025 as capacity comes online.
Meta: 5‑year, ~$3B AI infrastructure contract, with capacity deployment within three months post‑Q3 2025 earnings announcement, accelerating 2026 revenue contribution.
These two agreements alone lock in >$20B contracted revenue, effectively underwriting the majority of 2026E revenue and providing line‑of‑sight to multi‑year hyper‑growth.

Q3 2025 revenue of $146.1M (+355% YoY) reflects early scaling of the platform before full Microsoft/Meta activation, with a steepening trajectory into 2025–2026.
Core AI infrastructure Adjusted EBITDA margin expanded from breakeven in Q2 2025 to 19% in Q3 2025, with management targeting a glide‑path toward 30%+ as utilization and mix optimize.
Nebius ended Q3 2025 with $4.8B in cash (up 97% vs. YE 2024) and >$10B in total assets, providing balance sheet capacity to support accelerated GPU and data center capex.

Data center footprint expanded aggressively in Q4 2024–2025:
- UK: London‑area facility with NVIDIA Blackwell Ultra GPUs and Quantum‑X800 InfiniBand, positioning Nebius as a sovereign AI enabler in a key European market.
- US: Vineland, NJ site dedicated to Microsoft, representing Nebius’s primary US hyperscaler anchor deployment.
- Finland: Mäntsälä expansion to 75 MW (up to 60,000 GPUs), forming a major European AI hub.
- France: Paris data center with NVIDIA H200 GPUs, among the first advanced deployments in Europe.
Capacity roadmap targets >2.5GW contracted power and 800MW–1GW connected power by 2026, implying >5x growth in connected capacity vs. Q3 2025 (~200MW).

Growth funded via a mix of:
- Secured debt against high‑quality Microsoft and Meta receivables, lowering funding risk and cost of capital.
- Equity: $1B follow‑on in September 2025 plus ATM program (up to 25M shares) to opportunistically raise equity in a dilution‑sensitive manner as the story re‑rates.
Capital intensity remains structurally high, but the combination of contract‑backed debt and staged equity should support the build‑out while preserving upside for existing shareholders if execution is on‑plan.

Nebius trades at ~2.5x 2026E ARR versus an implied 10x sector “AI infra” peer multiple, suggesting up to ~4x upside on a 10x 2026E revenue framework if execution tracks guidance.
The majority of 2026E revenue is contract‑backed (Microsoft + Meta + core AI cloud), reducing forecast dispersion and supporting a thesis of multiple expansion on rising visibilityrather than purely growth‑driven appreciation.

Initial revenue recognition from Microsoft and Meta (Q4 2024–Q2 2025) validating margin structure and cash conversion of mega‑contracts.
Achieving 1GW connected power milestone in 2026, demonstrating delivery capability on an aggressive infrastructure roadmap.
Transition to sustained consolidated profitability in 2025, broadening the investor base and enabling cheaper capital.
Additional hyperscaler/sovereign AI wins, particularly in Europe, that further entrench Nebius as the default non‑US sovereign AI infrastructure partner.

Execution risk around a planned ~10x capacity expansion, with potential construction delays, GPU supply constraints, or deployment bottlenecks.
Customer concentration, with a large share of forward revenue tied to Microsoft and Meta, increasing exposure to contract renegotiation, ramp risk, or strategic shifts.
Capital intensity and funding requirements could necessitate incremental equity or higher‑cost debt if markets dislocate or execution stumbles.
Competitive pressures from hyperscalers (AWS, Google Cloud) and specialist peers (e.g., CoreWeave) that may affect pricing, share of wallet, and incremental contract wins.

Nebius is positioned as a high‑conviction, high‑velocity AI infrastructure compounder with unusually high revenue visibility, a full‑stack technical moat, and a differentiated sovereign AI narrative.
For growth‑oriented mandates capable of underwriting execution and capital‑intensity risk, NBIS screens as a strong buy with asymmetric upside if 2026 ARR and margin targets are met.
