MARA MARA Holdings Inc

MARA (NASDAQ: MARA) ("MARA" or the "Company"), a global leader in leveraging digital asset compute to support the energy transformation, today published unaudited bitcoin (“BTC”) production and mining operation updates for January 2025.

Management Commentary

"In January, our production saw a 12% month-over-month decline in blocks won, largely due to fluctuations in network difficulty and intermittent curtailment," said Fred Thiel, MARA's chairman and CEO. "After a very busy end of 2024 during which we relocated and brought online over 100,000 miners, our energized hashrate remained consistent with December, as no new miners were brought online during the month.

"We remain focused on optimizing our fleet and implementing strategic enhancements to drive long-term efficiency and performance. At Wolf Hollow, Texas, we successfully completed the conversion of over 230 containers to immersion cooling, achieving high uptime with our S21 Pro immersion miners. These fleet upgrades not only enhance efficiency but also increase hashrate without additional power consumption. Meanwhile, at our Kearney, Nebraska site, we are nearing full conversion to S21 Pros, which we expect to improve fleet efficiency significantly.

"Looking ahead, we are committed to expanding our mining capacity in 2025 and further strengthening our position as a leader in the BTC mining industry. Our strategy will prioritize near net zero cost energy solutions, and we look forward to sharing more on our earnings call at the end of the month."
