• Company mined 417 bitcoin; total bitcoin holdings now at 6,154

LAS VEGAS, June 4, 2024 /PRNewswire/ -- CleanSpark Inc. (Nasdaq: CLSK), America's Bitcoin Miner™, today released its unaudited bitcoin mining and operations update for the month ending May 31, 2024.

"We have outperformed industry expectations as well as our peers in our first full month of production after the block reward halving," said Zach Bradford, CEO. "Remarkably, our post-halving production has also outpaced what some of our peers achieved prior to the halving. We have continued with our progress and are making meaningful gains and upgrades. For example, we achieved a new high mark of nearly 18 exahashes per second while driving our efficiency even further to 23.05 joules per terahash. As we continue to grow our hashrate, we are on a trajectory to rapidly recover our production to pre-halving levels.

"Meanwhile, as we maximize the performance of our existing fleet, we remain highly active in the M&A space. We expect to close on the first site in Wyoming in the coming days and continue to aggressively seek additional opportunities that align with the CleanSpark way. We will continue to provide transparency and updates as we have them. In fact, we recently had our first-ever retail investor day, held at our immersion-cooled facility in Norcross, Georgia. I'd like to thank our investors who were able to take time out of their busy schedules to attend and meet with us."
