Nebius (NASDAQ: NBIS) has $40bn in AI contracts. Why borrow $3.5bn for one year?

Nebius Group N.V. (NASDAQ: NBIS), the Amsterdam-headquartered artificial intelligence cloud infrastructure company, has secured a US$3.5 billion senior secured financing facility from Citibank, N.A. to support data centre development and graphics processing unit procurement. Announced on October 22, 2026, the agreement provides additional capital for an expansion programme supported by more than US$40 billion in long-term customer commitments, including agreements involving Microsoft Corporation and Meta Platforms, Inc. However, the financing matures in October 2027, carries a floating interest rate and is backed by substantial borrower assets, making its eventual repayment or refinancing an important consideration. With Nebius shares closing at US$158.74 on October 23 after a volatile month for AI infrastructure stocks, investors face a central question: whether the new borrowing provides a cost-effective bridge to higher commercial revenue or introduces another financing commitment before the company’s enormous infrastructure investment begins generating sufficient sustainable cash flow.

Why does Nebius need another $3.5 billion despite its enormous AI customer contracts?

Nebius operates a specialised cloud computing platform that supplies artificial intelligence developers and enterprises with access to high-performance graphics processing units, networking infrastructure, data centres and software services. Unlike conventional software businesses, the company must invest heavily in physical infrastructure before much of the associated customer revenue can be recognised. Large GPU clusters require substantial expenditure on computing equipment, cooling systems, electricity infrastructure and data centre construction, often months before they become operational. This creates a significant difference between securing a customer commitment and having the cash required to deliver the contracted service.

The company’s more than US$40 billion in long-term customer commitments provide substantial visibility into potential future demand, but they do not represent an equivalent amount of cash immediately available for investment. Revenue associated with these agreements is recognised over the relevant service periods and depends on contractual delivery requirements being satisfied. Some customers provide advance payments that help finance construction, while other commitments may support dedicated borrowing arrangements. The amount of financing available against those contracts depends on lender assessments, contractual terms and the assets supporting the obligations.

The new Citibank facility is intended to address part of this timing difference. Nebius said the financing will support GPU procurement, data centre development and general corporate purposes while providing greater flexibility over the timing of future capital-raising transactions. Management has also identified additional financing opportunities backed by long-term customer commitments with investment-grade counterparties. The commercial logic is that access to funding today can accelerate deployment of infrastructure expected to generate revenue over several subsequent years.

However, the transaction does not eliminate the distinction between contracted future revenue and realised financial returns. Nebius must still deliver the computing capacity, meet customer requirements and generate sufficient operating earnings to support debt service and future infrastructure investment. The facility provides financing capacity for those activities rather than independently demonstrating that the underlying projects have already earned an acceptable return.

What do the one-year maturity and floating interest rate mean for Nebius shareholders?

The financing agreement was signed on October 17 and publicly announced on October 22. It provides for a US$3.5 billion senior secured term loan facility involving Nebius Group N.V., its United States subsidiary Nebius Inc. and its Netherlands subsidiary Nebius B.V. The contractual maturity date is October 16, 2027, giving the facility a term of approximately 364 days from signing. This makes it a relatively short-term financing arrangement compared with the multiyear operating lives of the data centres and computing systems that the proceeds may help finance.

The interest rate is linked to the Term Secured Overnight Financing Rate, commonly known as Term SOFR, plus an initial margin of 2.75 percentage points per year. That margin increases by 0.25 percentage points after each 90-day period, subject to a maximum of 3.50 percentage points and other contractual adjustments. The borrowing cost therefore depends on both the benchmark interest rate and the applicable margin during the period in which loans remain outstanding. It would be inaccurate to describe the facility as carrying a fixed 2.75% interest rate because that figure is only the initial spread above the floating benchmark.

The arrangement also contains a minimum liquidity covenant and other contractual obligations governing the borrowers. Security interests cover substantially all assets of the relevant borrowing entities, including specified subsidiary shares held by the parent, subject to exclusions and permitted liens. These terms give the lender contractual protections and differentiate the new financing from unsecured corporate borrowing. They should not be interpreted as evidence of imminent financial distress, but they matter when considering the company’s future financing flexibility.

Nebius can voluntarily prepay the facility without a contractual premium or penalty under the disclosed terms. This provides flexibility if the company completes longer-term financing, generates sufficient cash or replaces part of the borrowing with another funding source before maturity. Nevertheless, the October 2027 deadline means that management will need a credible plan for the outstanding balance, whether through repayment, refinancing or an alternative arrangement. The transaction is therefore best understood as an additional near-term funding resource rather than a permanent solution to the capital requirements of the entire expansion programme.

How strong is Nebius Group’s balance sheet after its previous debt financing?

Nebius entered the latest financing arrangement after substantially expanding its access to capital during 2026. At June 30, the company reported approximately US$8.04 billion in cash and cash equivalents, alongside approximately US$1.06 billion in restricted cash and cash equivalents. These balances provided considerable liquidity at the reporting date, although they preceded significant subsequent financing and investment activity. The June cash position should therefore not be presented as an exact measure of available cash immediately before the October facility was announced.

In August, Nebius completed a US$5.75 billion offering of convertible senior notes, comprising US$3.45 billion of notes due in 2030 and US$2.30 billion due in 2034. The two series carry annual coupon rates of 0.50% and 4.50%, respectively. Proceeds were intended to finance continuing infrastructure expansion and other corporate purposes. The transaction increased Nebius’s longer-term financing resources while creating additional obligations that must be considered when assessing its capital structure.

The convertible notes and the new secured facility have different economic characteristics. Convertible notes may eventually be settled according to their contractual conversion provisions, potentially affecting the share count or other financial obligations depending on their terms. The Citibank facility, by contrast, is a short-term secured borrowing arrangement with floating-rate interest and a defined maturity in October 2027. Neither instrument should be treated as automatically creating ordinary-share dilution simply because it provides access to capital.

Nebius has also used asset-backed financing to support specific infrastructure deployments. In July, it announced an approximately US$775 million secured facility associated with computing infrastructure and contracted customer cash flows. That arrangement demonstrated an ability to borrow against identifiable operating assets and customer relationships rather than relying exclusively on unsecured corporate debt or new equity issuance. The October facility broadens the available funding structure but also increases the importance of monitoring consolidated borrowing obligations and future financing transactions.

The latest publicly reported liquidity position does not establish the precise amount available after all subsequent spending and funding activity. Nebius has been deploying substantial capital into hardware and data centres, while the August convertible issuance and October facility altered its financing position. The next financial statements should provide a more complete assessment of cash, restricted balances, debt and contractual commitments. Such an assessment is more informative than simply adding every newly announced financing amount to an older reported cash balance.

Are Nebius’s rapid revenue growth and operating cash flow enough to support its expansion?

Nebius reported consolidated second-quarter revenue of US$582.3 million, representing growth of approximately 454% from US$105.1 million a year earlier. Adjusted EBITDA reached US$236.2 million, compared with an adjusted EBITDA loss of US$21 million in the corresponding period of 2025. These results demonstrate that the company is converting its growing computing infrastructure footprint into substantially higher reported revenue and positive adjusted operating earnings. Nevertheless, adjusted EBITDA excludes significant items including depreciation and share-based compensation, making it different from net profit or cash available for debt repayment.

The company reported a US$190.4 million net loss from continuing operations in the June quarter. Depreciation and amortisation reached approximately US$259.7 million, reflecting the cost of an expanding base of computing equipment and related infrastructure. Share-based compensation totalled approximately US$102.5 million during the period. These expenses illustrate why a fast-growing AI cloud business can generate positive adjusted EBITDA while remaining loss-making under generally accepted accounting principles.

The cash-flow statement provides another important distinction. Nebius generated approximately US$2.25 billion in operating cash flow during the second quarter, but changes in deferred revenue contributed approximately US$1.20 billion to that result. Across the first six months, deferred revenue movements contributed approximately US$4.40 billion to reported operating cash flow. Advance customer payments can be commercially valuable because they finance infrastructure before the related services are delivered, but they also create obligations to provide computing capacity in future periods.

The size of the investment programme remained much greater than quarterly operating cash generation. Nebius spent approximately US$5.66 billion on property, equipment and intangible assets during the June quarter, compared with approximately US$2.25 billion in operating cash inflow. The difference was roughly US$3.41 billion before other investing and financing activity. For the first six months, purchases of property, equipment and intangible assets reached approximately US$8.13 billion.

These figures explain why Nebius continues securing financing even as revenue grows rapidly and customer prepayments provide substantial cash. The business is attempting to expand computing capacity much faster than its existing operations could finance through recurring earnings alone. That investment may ultimately prove commercially attractive if commissioned facilities achieve strong utilisation and customer contracts generate the anticipated returns. However, the financial benefits must be evaluated over time rather than assuming that current adjusted profitability already supports the complete expansion programme.

Can the $40 billion AI contract portfolio justify Nebius’s growing financing commitments?

The scale and quality of customer commitments are central to Nebius’s financing strategy. Long-term contracts involving major technology companies can provide revenue visibility and make it easier to secure credit against infrastructure intended for identified customers. In its August shareholder communication, Nebius highlighted the role of long-duration agreements in supporting its asset-backed financing model. Management also indicated that many recent customer agreements included prepayments covering a substantial proportion of associated capital expenditure.

The company reported that contracts signed during the June quarter had an average total contract value exceeding US$1 billion across four major agreements. Management also described improving revenue potential per megawatt of contracted computing capacity and expected payback periods for selected new deals. Those estimates depend on forecast costs, deployment schedules, pricing and customer obligations, including capacity that was not yet operational. They are therefore useful indicators of management’s commercial assumptions rather than independently established returns from completed infrastructure.

Nebius has been expanding its data centre footprint across North America and Europe while targeting increasingly large AI computing deployments. In August, management raised its year-end contracted-power objective to approximately five gigawatts and discussed ambitions to deploy more than one gigawatt annually beginning in 2027. These targets indicate the scale of its planned investment but should not be confused with electricity capacity already connected to operating computing equipment. Contracted power, constructed data centres, installed GPUs and customer-billable computing services represent different stages of development.

The commercial benefit of the new Citibank facility will depend on how quickly those stages progress. Borrowing to complete infrastructure tied to signed customer contracts can create value if revenues and operating margins justify the financing costs. However, delays in power availability, equipment installation or customer acceptance could postpone revenue while interest and other financial commitments continue. The strongest evidence would be sustained growth in operating capacity and recognised revenue relative to capital expenditure and borrowing.

The distinction also affects how investors should interpret the more than US$40 billion contract figure. It represents substantial potential future business over multiple periods, not a pool of unrestricted cash or a guaranteed measure of operating profit. Customer payments must ultimately cover the costs of delivering the services, maintaining the equipment and financing the infrastructure. Nebius’s ability to achieve attractive returns will depend on that economic relationship rather than the headline size of its order commitments alone.

What does the $158.74 Nebius share price imply about the market’s expectations?

Nebius shares closed at US$158.74 on October 23, down approximately 0.3% during the session after falling 7.2% on October 22. The larger decline coincided with the financing announcement and broader selling pressure across artificial intelligence infrastructure stocks, making it inappropriate to attribute the entire market movement to the new facility. Using consistent closing prices, the stock was approximately 4.1% below its October 16 close of US$165.47 and around 34.8% below its September 24 close of US$243.48. The observed 52-week trading range extended from US$73.52 to US$299.86.

At the October 23 closing price, market data placed Nebius’s equity valuation at approximately US$43.5 billion, although estimates can vary modestly according to the share-count reference used. The valuation incorporates substantial expectations for future AI infrastructure revenue and earnings growth. Traditional trailing earnings multiples provide limited insight because reported results have been affected by investment valuations, rapid infrastructure expansion and considerable depreciation. A more useful assessment considers expected revenue from commissioned capacity, operating margins, future capital expenditure and financing costs together.

The current market valuation is also sensitive to the amount of additional capital required before the business reaches a more mature operating scale. New borrowing can be economically preferable to issuing shares if the associated projects generate returns exceeding the cost of debt. However, borrowing also creates contractual repayment obligations, while equity issuance can change the ownership percentage and earnings attributable to existing shareholders. The attractiveness of either funding method depends on the actual terms and the returns generated from the proceeds.

The recent share-price decline suggests that market expectations for the AI infrastructure sector have become more demanding. Investors are increasingly assessing financing costs, debt obligations and cash conversion alongside customer contract announcements. Nebius’s large contractual portfolio remains a significant commercial asset, but a sustained valuation recovery would likely require stronger evidence that the infrastructure behind those agreements is becoming operational and generating profitable revenue. The new facility improves near-term financing flexibility without removing that requirement.

What milestones could establish whether the Citi financing strengthens Nebius’s investment case?

The first measurable milestone is the company’s next quarterly financial disclosure, expected during November 2026. Investors will be able to assess the latest cash balance, outstanding financing obligations, infrastructure spending and reported operating performance. Updates on the availability and use of the Citibank facility would also clarify how the new borrowing is being incorporated into the company’s funding strategy. A stronger liquidity position accompanied by measurable infrastructure progress would provide more useful evidence than the facility announcement alone.

The second milestone is commercial deployment during 2027. Nebius has outlined plans for substantial increases in operating computing capacity, supported by customer agreements and development projects across several markets. Progress should be assessed through installed GPUs, connected power, operating facilities and recognised customer revenue rather than contracted capacity alone. Delays or material changes to customer deployment schedules could influence both future revenue and the timing of financing requirements.

The third milestone is the evolution of the company’s funding structure before October 16, 2027. The Citibank facility permits early repayment, potentially allowing Nebius to replace the borrowing with longer-term financing or other capital sources. Management has identified asset-backed borrowing and customer commitments as possible components of its future financing programme. However, the terms and availability of any subsequent transactions remain uncertain until definitive arrangements are disclosed.

Nebius’s financial position contains both meaningful strengths and unresolved requirements. Rapid revenue growth, positive adjusted EBITDA, substantial customer commitments and access to institutional capital demonstrate that the business has developed beyond an early-stage computing infrastructure concept. At the same time, its expansion demands enormous upfront investment, while the latest borrowing introduces a relatively near-term maturity that must be managed alongside existing financial obligations. The investment case would strengthen most clearly if the company could demonstrate that customer-backed infrastructure is generating enough operating cash to reduce dependence on successive rounds of external financing.

The US$3.5 billion Citibank agreement is therefore a meaningful step in Nebius’s financing strategy, but it is not the same as proving that the AI expansion can become financially self-sustaining. The company has secured additional capacity to fund growth while retaining the flexibility to refinance or repay the facility before maturity. What remains unresolved is how quickly its multibillion-dollar commitments translate into durable earnings and cash flow. The decisive test is whether the next phase of infrastructure deployment can justify the financing attached to it.

Key takeaways: What should investors watch after Nebius’s $3.5 billion financing?
