Forget margin or options. Here's how the pros trade NBISNebius Group N.V.’s latest earnings call struck an unusually bullish tone, underscoring breakneck demand for its AI cloud while acknowledging sizable execution and capital risks. Management highlighted sold‑out capacity, an expanding multibillion‑dollar pipeline and surging cash generation as evidence that the business is scaling fast, even as heavy 2026 CapEx and near‑term losses keep the risk profile elevated.
Explosive Top-Line Growth
Nebius reported Q4 group revenue of $228 million, up 547% year over year and 56% sequentially, signaling a steep growth curve rather than a one‑off spike. Core AI cloud revenue was the standout, surging 830% year over year and 63% quarter over quarter, underscoring the company’s positioning in the infrastructure race behind large‑scale AI workloads.
ARR Beat and Deeper Customer Commitments
Annualized run‑rate revenue reached $1.2 billion by December, surpassing the company’s own guidance and confirming that the revenue base is broadening quickly. At the same time, average contract duration for new cloud customers expanded by about 50%, suggesting that large clients are locking in Nebius capacity for longer and providing higher visibility on future cash flows.
Capacity Sold Out into 2026
Demand for infrastructure is running ahead of what Nebius can currently deliver, with management noting that capacity was sold out in both Q3 and Q4 and is effectively sold out into 2026. The company now has over 2 GW of contracted power and has raised its 2026 target to more than 3 GW, expecting 800 MW to 1 GW of connected capacity by year‑end.
Pricing Power and Expanding Pipeline
Despite rapid growth, Nebius said pricing remains firm across GPU generations, with no discounting on prior‑generation chips. Average selling prices have risen by more than 50% for longer‑duration deals, and the Q1 pipeline is on track to exceed $4 billion, indicating that demand is broadening even as the company pushes through higher price points.
Profitability Metrics Turn the Corner
The business delivered its first positive group adjusted EBITDA in Q4, with a 7% margin that signals early operating leverage. Core AI cloud margins were stronger still, rising from 19% in Q3 to 24% in Q4, while operating cash flow hit $834 million in the quarter, leaving Nebius with $3 billion of cash and a balance sheet capable of supporting near‑term buildout.
Capacity Buildout and New Products
To meet demand, Nebius unveiled plans for nine new data centers and a 2026 CapEx program of $16 billion to $20 billion. On the product side, it launched Token Factory and bought Tavily, adding agentic search capabilities and access to roughly 700,000 developers, moves that aim to deepen its AI ecosystem and drive higher‑value workloads onto its infrastructure.
Execution on Mega-Contracts
The company emphasized progress on flagship hyperscale contracts, noting that it is now fully servicing its agreement with Meta after delivering all contracted capacity. For Microsoft, the first tranche has been delivered on time, with further tranches staggered through 2026, mostly in the second half, positioning Microsoft to contribute full run‑rate revenue in 2027 if the ramp stays on schedule.
Funding Strategy and Balance Sheet Strength
Management said about 60% of the 2026 CapEx plan is already covered through existing cash, expected operating cash flow and committed funding. To bridge the remaining gap, Nebius is evaluating debt and asset‑backed structures and other capital options while keeping its at‑the‑market equity program untouched for now, preserving flexibility but leaving room for potential future dilution.
CapEx Concentration and Financing Risk
The sheer scale of the $16 billion to $20 billion 2026 CapEx plan introduces funding and execution risk, even with most of it preliminarily covered. Any need to lean harder on leverage or equity could pressure the company’s cost of capital or dilute shareholders, making capital allocation and project discipline critical as Nebius races to add capacity.
Back-Loaded Revenue and Timing Risk
A large portion of Nebius’s planned capacity, particularly related to the Microsoft build‑out, will only come online in the second half of 2026, driving a gap between current ARR of $1.2 billion and 2026 revenue guidance of $3.0 billion to $3.4 billion. That leaves results sensitive to any slippage in deployment schedules or delays in connecting power and GPUs to paying workloads.
Near-Term Losses Despite Growth
While adjusted EBITDA has turned positive, management expects EBIT to remain in the red through 2026 as Nebius continues heavy investments in capacity and R&D. Non‑core businesses are also projected to operate at EBITDA losses next year, meaning headline profitability will lag the rapid top‑line ramp even as core margins improve.
Stretch Margin Targets
The company is targeting a group adjusted EBITDA margin of roughly 40% in 2026, up sharply from 7% in Q4, and sees medium‑term EBIT margins in the 20% to 30% range. Achieving those goals will require a rapid revenue ramp, disciplined cost control and clean execution of the buildout, making the margin trajectory one of the key variables for equity investors to monitor.
Ongoing Supply Chain and Build Risks
Nebius said it has secured long‑lead items for its major contracts and uses a portfolio approach across sites to reduce dependence on any single data center. Even so, the company acknowledged that data center equipment shortages and the complexity of large‑scale builds remain operational risks that could impact deployment timelines and associated revenue.
Street Expectations vs. Company Guidance
One analyst flagged that Q4 revenue appeared light relative to consensus, even though ARR exceeded internal targets. Management responded that reported revenue landed in the middle of its guidance range, suggesting that any disappointment stems from Street expectations rather than a change in the company’s trajectory.
Bold Guidance and 2026 Roadmap
Nebius reiterated its aggressive 2026 outlook, aiming for ARR of $7 billion to $9 billion and revenue of $3.0 billion to $3.4 billion, alongside an approximate 40% adjusted EBITDA margin while EBIT stays negative. The plan rests on deploying over 3 GW of contracted power, bringing 0.8 GW to 1.0 GW online by year‑end, maintaining strong GPU pricing and ramping Meta and Microsoft contracts, all underpinned by robust Q4 momentum and a growing pipeline.
The earnings call painted a picture of a company riding a powerful AI infrastructure wave, with revenue, ARR and cash flow all inflecting sharply higher. For investors, Nebius offers outsized growth potential, but it is tightly coupled to an ambitious and capital‑intensive buildout, making execution, funding and deployment timing the critical swing factors over the next two years.
