CleanSpark's December 2025 Bitcoin Mining Update

On January 6, 2026, CleanSpark, Inc. (Nasdaq: CLSK), recognized as America’s Bitcoin Miner®, released an unaudited update regarding its Bitcoin mining and operations from December 2025. This announcement highlighted a robust production year, with Bitcoin output increasing by more than 10% compared to the previous year.

CEO Matt Schultz stated, "December closed 2025 with strong operational performance across our mining and Digital Asset Management divisions." This sentiment is echoed by the company achieving consistent mining efficiency despite challenges posed by increasing network difficulty.

Growth in Bitcoin Production

Throughout 2025, CleanSpark produced 7,746 Bitcoins, with December alone seeing 622 Bitcoins mined. The peak single day production reached 20.59 Bitcoins, with an average daily output of 20.07 Bitcoins. These figures demonstrate the company’s commitment to maintaining robust operational strengths, particularly as it navigates the evolving cryptocurrency landscape.

As part of its innovative strategy, CleanSpark is not only focusing on Bitcoin mining but has also ventured into AI data centers. The company's ongoing projects in Georgia and Texas are set to bolster their presence in both sectors, allowing them to harness strategic energy opportunities to promote long-term growth.

Demand Response Strategy

A noteworthy feature of CleanSpark’s operational strategies is its demand response capability. In December, during an extreme cold spell in Tennessee, CleanSpark adeptly reduced its Bitcoin mining power consumption across its eleven sites by hundreds of megawatts at the request of the Tennessee Valley Authority (TVA). This swift action exemplifies the effectiveness of CleanSpark's customized communications system and underscores the firm's dedication to being a responsible partner to utility companies.

Scott Garrison, Chief Development Officer, remarked, "This curtailment underscores our commitment to act as a reliable partner to our local utilities and communities. Our technology and operational discipline allow us to respond effectively during emergency demands, ensuring the stability of the local grid."

Strategic Milestones in 2025

In 2025, CleanSpark achieved several strategic milestones that mark its evolution in the industry:

• - The company transitioned from being solely a Bitcoin miner to incorporating AI computing solutions. This transformation was highlighted by the hiring of Jeffrey Thomas as Senior Vice President of AI Data Centers.

• - The firm acquired a 271-acre site in Texas, which includes long-term power supply agreements totaling 285 megawatts, facilitating the establishment of its AI data center.
• - Additionally, CleanSpark successfully closed on a $1.15 billion zero-coupon convertible notes offering, which is set to enhance its power portfolio.
