- The debt issuance consists of two tranches: $2.75B maturing in 2030 and $1.75B maturing in 2034

Shares of Nebius Group (NBIS) tumbled more than 8% during Wednesday’s premarket session following the company’s disclosure of a $4.5 billion convertible senior notes offering.
The debt raise is structured in two separate tranches. The initial tranche comprises $2.75 billion in convertible notes with a maturity date of February 15, 2030. The secondary tranche consists of $1.75 billion in convertible notes maturing on February 15, 2034.
Each tranche will be marketed exclusively through private placement channels to qualified institutional buyers.
Nebius is additionally granting initial buyers an option to acquire supplementary notes. This option encompasses up to $375 million for the 2030 tranche and up to $300 million for the 2034 tranche, with a 13-day exercise window following the initial issuance.
Should these optional purchases be fully exercised, the aggregate capital raise could exceed $5.1 billion.
Allocation of Capital
According to the company’s statement, the raised capital will be directed toward supporting its ongoing business expansion initiatives. This encompasses the construction and enhancement of its data center facilities, advancement of its comprehensive AI cloud infrastructure platform, and acquisition of critical hardware components such as GPUs.
Any surplus funds will be allocated to general corporate operations.
Existing Debt Exchange Initiative
In conjunction with the new debt issuance, Nebius plans to negotiate exchange agreements with select current noteholders. These holders possess the company’s 2.00% Convertible Senior Notes maturing in 2029 and 3.00% Convertible Senior Notes maturing in 2031.
Through these agreements, certain portions of the outstanding notes would be exchanged for Nebius Class A ordinary shares, each carrying a par value of ā¬0.01.
This transaction essentially transforms a portion of corporate debt into equity ownership, potentially diluting current shareholders’ positions.
The combination of potential shareholder dilution and the substantial magnitude of the new debt offering appears to be driving the significant premarket decline in NBIS shares.
The stock initially fell more than 6% immediately following the announcement, subsequently deepening its losses to surpass 8% as premarket activity progressed.
Both the 2030 and 2034 note series will reach maturity on February 15 of their designated years, requiring repayment of the initial principal amount plus any accumulated interest.
