MARA Announces Bitcoin Production and Mining Operation Updates for April 2025

Energized Hash Rate Grew 5.5% to 57.3 EH/s
Increased BTC Holdings* to 48,237 BTC

Fort Lauderdale, FL, May 05, 2025 (GLOBE NEWSWIRE) -- MARA Holdings, Inc. (NASDAQ: MARA) ("MARA" or the "Company"), a vertically integrated digital energy and infrastructure company that leverages high-intensity compute, such as bitcoin ("bitcoin" or "BTC") mining, to monetize excess energy and optimize power management, today published unaudited bitcoin production updates for April 2025.

Management Commentary

"In April, our production saw a 15% month-over-month decrease in blocks won, as global hashrate had its second largest monthly gain on record and mining difficulty grew 8% from March," said Fred Thiel, MARA's chairman and CEO. "Despite these headwinds, our energized hashrate grew 5.5% over the prior month. We completed a 50-megawatt ("MW") expansion at our fully owned data center in Ohio, bringing total operational capacity to 100 MW, with the site designed to scale up to 200 MW. Additionally, we installed over 12,000 S21 Pro miners at the location.

"Last month, we fully energized our 25 MW gas-to-power operations across wellheads in North Dakota and Texas. These sites currently provide us with our lowest cost per BTC mined while monetizing excess gas and mitigating methane emissions for the producers.

“We remain laser-focused on transforming MARA into a vertically integrated digital energy and infrastructure company. We believe this model gives us tighter operational control, improves cost-efficiency, and makes us more resilient to shifts in the broader economy.”
