MARA Announces Bitcoin Production and Mining Operation Updates for August 2025

208 Blocks Won in August

Increased BTC Holdings* to 52,477 BTC

Miami, FL, Sept. 04, 2025 (GLOBE NEWSWIRE) -- MARA Holdings, Inc. (NASDAQ: MARA) ("MARA" or the "Company"), a leading digital energy and infrastructure company, today published unaudited bitcoin ("bitcoin" or "BTC") production updates for August 2025.

Management Commentary

"Similar to last month, we produced 208 blocks in August as global hashrate increased 6% month-over-month to an average of 949 EH/s," said Fred Thiel, MARA's chairman and CEO. "Given the decline in bitcoin price during the month, we took the opportunity to strategically add to our treasury and currently hold over 52,000 BTC.

"Our energized hashrate grew 1% over the prior month, and all containers and miners at our Texas wind farm are on-site and connected. We are on track to be fully operational at the site in the fourth quarter.

"We recently announced the signing of an investment agreement allowing MARA to acquire a 64% stake in Exaion, a subsidiary of EDF, one of the world's largest low-carbon energy producers, with the option to increase our ownership up to 75% by 2027. The transaction is expected to close in or around Q4 2025, subject to customary closing requirements and regulatory approval. Upon closing, this joint venture would formalize the convergence of our technology stack and AI in developing new solutions that can lower the cost of processing and secure the edge infrastructure that will support the growing AI economy. Furthermore, we established our European headquarters in Paris and welcomed European business leaders to accelerate our international growth strategy. Together, these announcements reinforce MARA's role in advancing energy partnerships dedicated to stabilizing power grids while capturing and repurposing unused energy."
