[6-K] Nebius Group N.V. Current Report (Foreign Issuer)

Rhea-AI Filing Summary

Nebius Group N.V. announced a commercial agreement under which its subsidiary will provide Meta Platforms access to two dedicated GPU infrastructure capacity clusters over a five-year term. The first order under the agreement has a total contract value of approximately $2.9 billion, with deployments planned in two tranches during December 2025 and February 2026, along with storage and connectivity services.

Meta may extend the term and/or purchase additional services or capacity. The company states that cash flow from the agreement will be used to finance part of the related capital expenditures. If, after a grace period, Nebius misses agreed delivery dates for the first tranche, Meta can terminate the order; after the first tranche is live, failure to meet second‑tranche delivery dates allows termination of the second tranche only. The documents include customary terms such as service levels, discounted monthly fees for late delivery, representations and warranties, indemnities, and limitations of liability.

$2.9B, 5-year GPU capacity deal with staged delivery and SLAs.

The agreement commits Nebius to deliver two dedicated GPU clusters to Meta over five years, with tranche deployments in December 2025 and February 2026. The order’s total contract value is $2.9 billion, and includes associated storage and connectivity, indicating a comprehensive infrastructure scope.

Revenue realization depends on timely delivery and service performance. The agreement lists customary service level commitments and discounted monthly fees for late delivery. Termination rights are asymmetric by tranche: missing the first‑tranche dates can terminate the entire order (after a grace period), while missing second‑tranche dates can terminate only that tranche once the first is live.

Cash flows from the agreement will be used to fund part of related capex, aligning inflows with buildout costs. Actual impact will track deployment milestones in December 2025 and February 2026 and ongoing SLA adherence.

COMMERCIAL AGREEMENT WITH META

As of November 1, 2025, Nebius, Inc. (the “Company”), a wholly owned subsidiary of Nebius Group N.V., entered into a commercial agreement (the “Agreement”) with Meta Platforms, Inc. (“Meta”), pursuant to which, under the first order form under that Agreement (the “Order”), the Company will provide Meta access to two dedicated GPU infrastructure capacity clusters (each, a “GPU Service”) over a five-year term.

The GPU Services will be deployed in two tranches during December 2025 and February 2026, along with associated storage and connectivity services. The Order has a total contract value of approximately $2.9 billion. Meta may also extend the term of the GPU Services and/or acquire additional services and/or capacity under the Agreement. Cash flow coming from the Agreement will be utilized to finance part of the capital expenditure associated with the Agreement.

In the event that, following a grace period, the Company fails to meet agreed delivery dates for the first tranche of the GPU Services, Meta has the right to terminate the Order. Once the first tranche is live, if, following a grace period, the Company fails to meet agreed delivery dates for the second tranche of the GPU Services, Meta has the right to terminate that second tranche of GPU Services but not the first tranche.

The Agreement and Order contain customary provisions for an agreement of this nature, including termination, service level commitments, discounted monthly fees for late delivery, representations and warranties, indemnities, and limitations of liability.
