MARA to Acquire Majority Stake in EDF’s HPC Subsidiary Exaion for $168 Million

Bitcoin mining giant MARA has agreed to acquire a 64% stake in Exaion, the high-performance computing (HPC) subsidiary of French energy giant EDF, in a deal valued at approximately $168 million.

According to MARA’s announcement on Monday, it will have the option to raise its ownership to 75% by 2027 through an additional investment of about $127 million, contingent on meeting certain milestones.

Exaion operates HPC data centers and provides cloud and AI infrastructure services, working with partners including NVIDIA, Deloitte, and 2CRSI. The EDF-founded company caters to enterprise and public-sector clients requiring high standards of data protection and performance.

Following the transaction, which is expected to close in the fourth quarter of 2025 pending regulatory approvals, MARA will become a strategic shareholder and plans to scale Exaion’s operations internationally. EDF will retain a minority stake and remain a client, signaling continued support for Exaion’s growth strategy.

MARA said the acquisition aligns with its push into AI and HPC infrastructure development, part of a growing trend of Bitcoin mining companies diversifying revenue amid the network’s continued hashprice squeeze.
