CleanSpark Releases January 2025 Bitcoin Mining Update

626 bitcoin mined and 40 EH/s surpassed in operating hashrate

More than 8% fleet efficiency improvement month over month

LAS VEGAS, Feb. 4, 2025 /PRNewswire/ -- CleanSpark, Inc. (Nasdaq: CLSK), America's Bitcoin Miner® (the "Company"), today released its unaudited bitcoin mining and operations update for the month ending January 31, 2025.

"CleanSpark powered through January, continuing to improve efficiency and reach new milestones despite historic weather events across several of our regions. We crossed the 40 EH/s milestone, achieved more than 10,500 bitcoin held in treasury, and celebrated the five-year anniversary of our uplisting on Nasdaq by ringing the bell last week," said Zach Bradford, CEO and President of CleanSpark. "Now, the entire team is focused on executing our path to 50 EH/s and building on our top three position across operating hashrate, marginal cost per coin, fleet efficiency, bitcoin held, and total uptime. This month we saw our interruptible power contracts in action as we curtailed portions of the portfolio during extreme cold weather events. We demonstrated our ability to support our utility and community partners, specifically during the coldest five days, and the benefit to our broad regional portfolio strategy by mitigating downtime in the Southeast with limited interruption across our other regions. Despite the weather, construction in Tennessee, Georgia, and Wyoming continues as we march toward our midyear goal."
