MARA Holdings partners with EDF Pulse Ventures, acquiring a 64% stake in Exaion to enhance AI and HPC infrastructure globally, with plans to increase its stake to 75% by 2027.

MARA Holdings, Inc. (NASDAQ: MARA), a prominent digital energy and infrastructure firm, has announced a strategic investment agreement with EDF Pulse Ventures, the corporate venture arm of EDF, a leading low-carbon energy producer. This collaboration will see MARA acquire a 64% stake in Exaion, an EDF subsidiary, with an option to increase its ownership to 75% by 2027, according to MARA.

Enhancing Global AI and HPC Infrastructure

Exaion specializes in high-performance computing (HPC) data centers, offering secure cloud and AI infrastructure solutions in collaboration with industry leaders such as NVIDIA, Deloitte, and 2CRSI. The investment aims to bolster MARA’s capabilities in AI and HPC infrastructure, meeting the growing demand for secure cloud solutions across enterprise and public sector clients.

Upon completion of the transaction, MARA will become a strategic shareholder, facilitating Exaion’s transition to a larger-scale international commercial deployment. The integration of Exaion’s platform and expertise is expected to significantly enhance MARA’s service offerings in the AI and HPC domains.

Investment Details and Strategic Goals

Under the agreement terms, MARA will invest approximately $168 million upfront for its initial stake, with provisions to invest an additional $127 million to expand its holding, contingent on specific milestones. The transaction is projected to conclude in the fourth quarter of 2025, pending regulatory approvals.

Fred Thiel, MARA’s Chairman and CEO, highlighted the strategic importance of this partnership, stating, “Our collaboration with Exaion brings together global leaders in data center development and digital energy. This synergy will enable us to deliver secure, scalable cloud solutions tailored for the future of AI.”

EDF’s Continued Involvement and Future Prospects

EDF will maintain a minority interest in Exaion, continuing as a client and underscoring its confidence in Exaion’s strategic direction. Julien Villeret, Head of Innovation at EDF Group, remarked on the partnership’s potential, stating that it marks a significant opportunity for Exaion to accelerate its technological and international development.

As the energy sector increasingly prioritizes data protection and energy efficiency, this partnership positions MARA and Exaion to address these critical needs with their combined expertise in digital and energy solutions.
