Nebius Group N.V. (NasdaqGS:NBIS) entered into an agreement and plan of merger to acquire Eigen AI, Inc. for approximately $620 million on May 1, 2026. The consideration will be paid in a combination of cash and Nebius?s Class A shares with aggregate value as of signing, based on Nebius?s 30-day weighted average stock price. Following close, Eigen AI?s inference and post-training optimization layers will be integrated directly into Nebius Token Factory, which provides enterprise-grade autoscaling endpoints and fine-tuning pipelines across all major open-source models.

The transaction is expected to close in the coming weeks, subject to certain customary conditions, including antitrust clearance. Axom Partners acted as financial advisor and Davis Wright Tremaine LLP acted as legal advisor for Eigen AI, Inc
