Neutral Impact 3 of 5 financing Written later

CleanSpark entered a side letter on September 18, 2025 that raises the aggregate lending capacity of its Master Loan Agreement with Coinbase to $300 million. The company said it will use the draws, secured by Bitcoin and other collateral, for capital expenditures such as energy portfolio expansion, Bitcoin mining and high-performance computing. Shareholders should note the facility requires ongoing collateral maintenance, and failure to meet it can lead to default and liquidation of pledged collateral.
