CleanSpark announces December bitcoin mining update

CleanSpark (CLSK) released its unaudited Bitcoin (BTC-USD) mining and operations update for the month ended December 31, 2025. “December closed 2025 with continued strong operational performance across our mining operations and Digital Asset Management groups,” said Matt Schultz, CleanSpark Chief Executive Officer and Chairman. “We grew bitcoin production more than 10% year over year despite ongoing network difficulty increases. Our operational strength and active monetization strategies are creating a durable foundation as we advance AI infrastructure plans in Georgia, Texas, and beyond. We are making strong progress with potential tenants and will continue pursuing strategic energy opportunities to support long-term portfolio growth.” In Tennessee, CleanSpark briefly curbed its Bitcoin mining power consumption last month by hundreds of megawatts during one of the coldest days of the year as part of long-established flexible consumption capabilities. The Company powered down operations across 11 sites in the state within 10 minutes of the Tennessee Valley Authority’s request, enabled by CleanSpark’s customized communications system. CleanSpark’s software team developed an integration which allows TVA to swiftly coordinate a curtailment of power including the length and volume needed to be returned to the grid in times of emergency or increased demand due to extreme weather events. This ability is called demand response and helps balance supply and demand, prevents blackouts, and reduces the need for additional power plants or infrastructure. Bitcoin produced in December totaled 622, with 7,746 produced for 2025.
