Nebius Secures Oversubscribed Bond Offering to Fuel AI Infrastructure Growth

Nebius upsizes convertible bond offering to $4.34B, backed by Meta and Microsoft prepayments, to fund GPU data centers and AI cloud platform development.

Nebius has successfully increased the size of its convertible bond offering to $4.34 billion, surpassing its initial target of $3.75 billion. The oversubscription signals robust confidence from institutional investors in the AI infrastructure provider's expansion strategy. Despite this vote of confidence, the company's share price experienced a decline of nearly three percent on the announcement.

Capital Allocation and Strategic Backing

The freshly raised capital is earmarked for a significant acceleration of its GPU infrastructure. This includes investments in high-performance chips, the construction of new data centers—with a major site planned for Birmingham, Alabama—and the ongoing development of its AI cloud platform.

A notable aspect of Nebius's broader investment plan, which calls for capital expenditures between $16 and $20 billion by 2026, is its funding structure. Approximately 60% of this substantial outlay is expected to be covered by prepayments from major customers, thereby reducing the firm's immediate need for additional external debt financing.

These prepayments are backed by industry giants. Meta has secured infrastructure services valued at $27 billion, while Microsoft has entered into a $17.3 billion supply agreement. Furthermore, Nvidia has already invested $2 billion in the company through warrants.

Offering Details and Market Reaction

The financing was structured in two tranches. The first consists of $2.59 billion in notes carrying a 1.25% interest rate and maturing in 2031. The second tranche offers $1.75 billion at a 2.625% rate, due in 2033. Both tranches feature conversion premiums in the range of 55% to 57.5%. Initial purchasers also hold a 13-day option to acquire an additional $262.5 million of the 2033 notes.

The share price dip following the announcement is likely attributable to the dilutive effect typical of large convertible bond issues. However, analysts maintain a positive medium-term outlook. BWS Financial and DA Davidson recently raised their price targets to $200, and Citigroup initiated coverage with a $169 target.

With this multi-billion dollar deal finalized, Nebius is now well-capitalized for its current infrastructure build-out. The key benchmarks moving forward will be the timely commissioning of its announced data center capacity and the conversion of its tech partners' prepayments into realized revenue.
