Nebius announces multi-billion dollar agreement with Microsoft for AI infrastructure

• Deal enables significantly more aggressive growth of Nebius's AI cloud business in 2026

Nebius Group N.V. (NASDAQ:NBIS) ("Nebius" or the "Company"), a leading AI infrastructure company, today announced an agreement to deliver AI infrastructure to Microsoft.

Under this multi-year agreement, Nebius will deliver dedicated capacity to Microsoft from its new data center in Vineland, New Jersey starting later this year.

Arkady Volozh, founder and CEO of Nebius, said:

"Nebius's core AI cloud business, serving customers from AI startups to enterprises, is performing exceptionally well. We have also said that, in addition to our core business, we expect to secure significant long-term committed contracts with leading AI labs and big tech companies. I'm happy to announce the first of these contracts, and I believe there are more to come. The economics of the deal are attractive in their own right, but, significantly, the deal will also help us to accelerate the growth of our AI cloud business even further in 2026 and beyond."

Nebius expects to finance the capital expenditure associated with the contract through a combination of cash flow coming from the deal and the issuance of debt secured against the contract in the near term, at terms enhanced by the credit quality of the counterparty. The Company is also evaluating a number of additional financing options to enable significantly faster growth than originally planned and will update the market on its financing strategy in due course.

More information about the contract can be found in the Company's 6-K filed today with the Securities and Exchange Commission.
