Nebius reported a 571% sales jump, a $40–45 billion build-out and a breakeven date in late 2027, according to ad-hoc-news.de.
Nebius closed Friday down 9.6%, and the sell-off has put one question at the center of the investment case: can the company fund its sprawling data-center expansion without falling behind its own timetable? Investors are weighing large contractual commitments against the risk that new capacity takes longer than promised to start generating revenue.
The results published Thursday offer a mixed picture. Revenue in the third quarter of 2026 reached $980.8 million, a 571% jump year on year. However, $325.1 million of that total came from one-off proceeds tied to strategic partnerships. The unaudited figures were released Thursday.
That split matters for anyone valuing the stock. Growth durability, not headline pace, is what counts. One-off partnership income flatters the reporting quarter, but recurring customer revenue and reliably available prepayments are what will ultimately finance a sustained build-out.
**Prepayments Are Meant to Carry the Load**
Management expects customer prepayments and asset-backed financing to cover 75–85% of 2027 investments, a capital program penciled in at $40–45 billion. This coverage ratio is the key test, as it defines how much of the expansion customers and lenders are expected to fund up front.
That expectation is not a certainty. The money has to arrive on time, and financing has to be available when needed. If a facility's start-up slips, those timing assumptions become even more critical.
For 2027, Nebius projects prepayments of $17–20 billion. That figure explains why contract structure matters as much as revenue growth. In the best case, Nebius collects substantial funds before delivering the service, easing the financing burden, provided the payment schedule and spending needs line up.
Contracts signed during the third quarter of 2026 offer an encouraging signal. According to the company, associated prepayments covered more than 100% of the capex for that capacity, and more than 90% of contract value was tied to prepayments. If future deals match that quality, Nebius could add capacity with considerable customer support, easing the immediate funding pressure, assuming the agreed payments arrive and the facilities perform as contracted.
Management's view on demand supports this outlook. Executives say the delays concern timing rather than demand, and that none of the postponed capacity has been cancelled.
**Where the Cash Flow Pinches**
The bear case starts with cash generation. Operating cash flow in the third quarter of 2026 was $273 million, even as adjusted EBITDA came in at $465.8 million. Because that adjusted result landed in a quarter boosted by sizable one-off revenue, investors should watch closely how cash inflows and recurring revenue evolve once such contributions fade.
Execution risk at third-party data centers adds another layer. Thursday's results made clear that some capacity has slipped into next year. The remaining Microsoft deliveries at the Vineland, New Jersey site are now slated for the second quarter of 2027.
The troubling scenario combines further delays with weaker prefinancing. Expected revenue would arrive later while the build-out continues to consume capital. Funding would become harder if customer payments and secured loans fall short of their intended share of investment.
**Two Dates to Watch**
The next hard checkpoint is the annualized revenue target, now pushed to February 2027. After that comes the remaining Microsoft capacity in the second quarter of 2027. Both milestones tie the financing question directly to operational delivery.
Guidance for 2027 stands at $12–13 billion in revenue, with delays shifting part of the expected top line into the first half of 2027. Management also expects to reach pre-tax breakeven in the fourth quarter of 2027, a timeline that requires patience and gives investors a yardstick for the coming investments. Anyone bullish on the growth story must also account for slippage along the way.
For the full year 2026, Nebius expects revenue at the low end of its prior $3–3.4 billion range while raising its capex plan. That combination sharpens the tension between build speed and dependable revenue recognition. Reuters reported that the shares fell after the more cautious revenue outlook and the higher spending plan.
In the near term, commentary on payment schedules, project progress and available financing will carry the most weight. Confirmation of the expected prefinancing and delivery plans would support a more favorable read. Further slippage, by contrast, would raise the risk of a longer funding gap between capital outlays and recurring revenue.
