Nebius Group N.V. (NASDAQ: NBIS) delivered the kind of top-line acceleration that AI infrastructure investors wanted to see in its first-quarter 2026 report, but the bigger takeaway may be how aggressively the company is scaling for the next phase of demand. Nebius reported Q1 revenue of $399.0 million, up from $50.9 million a year earlier, while also announcing that it has secured up to 1.2 gigawatts of power and land for a new owned AI factory site in Pennsylvania.
That combination matters more than a simple headline beat. Nebius has been trading more like an AI capacity story than a conventional software company, so the central question is whether demand growth is keeping pace with the capital intensity of the build-out. On the revenue line, the answer looked strong. On the spending side, the quarter also showed just how expensive that expansion path remains.
Revenue scale is arriving fast
The headline figure was hard to miss. Revenue rose 684% year over year to $399.0 million in the March quarter, according to the company’s earnings release. That is a sharp step-up for a business that had been framed primarily around future capacity and customer traction rather than current scale.
Nebius also reported adjusted EBITDA of $129.5 million, versus an adjusted EBITDA loss of $53.7 million a year earlier. Reported net income from continuing operations swung to $621.2 million from a loss of $104.3 million, although adjusted net loss still widened to $100.3 million from $83.6 million. That mix suggests investors should be careful about reading the GAAP profit number as the cleanest indicator of the underlying operating trend.
The more durable signal is that the business is now producing a much larger revenue base while keeping enough margin progress to show that growth is not purely theoretical. For a company that ended 2025 talking about rapid AI cloud expansion, Q1 offered evidence that enterprise demand is starting to show up in reported numbers.
The cost structure still tells the real story
Nebius is not scaling cheaply. Cost of revenue climbed to $103.8 million from $24.7 million, product development expense rose to $67.4 million from $36.5 million, and sales, general and administrative expense increased to $143.8 million from $60.9 million. Depreciation and amortization also jumped to $212.0 million from $49.1 million.
Those figures underline the real investor debate around the stock. Nebius is clearly building into demand, but it is doing so with a cost base that is expanding almost as visibly as revenue. Purchases of property and equipment and intangible assets reached $2.47 billion in the quarter, up from $543.9 million a year earlier.
That capex line makes the Pennsylvania announcement more than a side note. By securing up to 1.2 GW of power and land for another owned AI factory, Nebius is signaling that it sees enough medium-term demand to keep leaning into infrastructure ownership rather than simply optimizing for near-term earnings optics.
Why the Pennsylvania site changes the frame
The new Pennsylvania site sharpens the investment case because it extends the discussion beyond one quarter’s revenue print. If Nebius can fill that capacity with high-value AI training and inference workloads, the company strengthens its argument that it is becoming a serious independent AI cloud platform. If utilization lags, however, the capital burden could become much harder for investors to ignore.
That is why management commentary on customer wins, workload mix, and deployment timing may matter as much as the income statement itself. The stock’s long-term case depends on Nebius proving that it can translate infrastructure build-out into recurring, scalable demand rather than just faster spending.
The quarter did offer one encouraging signal on operating leverage. Cost of revenue fell to 26% of sales from 49% a year earlier, while product development dropped to 17% of revenue from 72%. Sales, general and administrative expense also improved meaningfully as a percentage of revenue, falling to 36% from 120%. Those ratios suggest the business is getting more efficient as it grows, even if absolute spending remains high.
What investors should focus on next
Nebius now has a clearer burden of proof. After this quarter, investors have more evidence that the revenue engine is real. The next test is whether that growth can stay strong enough to justify multi-billion-dollar infrastructure commitments.
That means future quarters will likely be judged on three things: how quickly new capacity is monetized, whether adjusted profitability can hold up as depreciation and capex climb, and whether customer traction broadens beyond the current narrative of AI infrastructure scarcity. A 684% revenue increase gets attention. Proving that it can compound into durable returns on all this spending is what will determine whether the story holds.
Key Signals for Investors
Q1 revenue of $399.0 million showed Nebius is moving from AI narrative to real operating scale.
Adjusted EBITDA turned positive, but adjusted net loss still shows the business remains in an investment-heavy phase.
The $2.47 billion capex line and new Pennsylvania site make capacity utilization the next critical metric.
Expense ratios improved sharply as a share of revenue, which is an early sign of operating leverage if growth holds.
Future valuation support likely depends more on customer demand and infrastructure fill rates than on one quarter’s GAAP profit.
