Biggest changeThe increase was primarily attributed to an increase in the average price of bitcoin during the year ended December 31, 2024 of $65,824 as compared to $28,788 during the same period in the prior year and an increase in mining capacity at the Lake Mariner Facility to approximately 195 MW as of December 31, 2024 as compared to 110 MW as of December 31, 2023, partially offset by decreases in the total bitcoin mined due to impacts of the halving in April 2024 and the increase in network hashrate, resulting in total bitcoin mined of 2,177 bitcoin during the year ended December 31, 2024 as compared to 2,168 bitcoin during the same period in the prior year.
Biggest changeAlthough the Company expanded its mining infrastructure capacity at the LMD Bitcoin Mining Facilities to approximately 245 MW as of December 31, 2025 as compared to 195 MW as of December 31, 2024, total bitcoin mined decreased due to the halving in April 2024 and the increase in network hashrate.

Bitcoin Mining - Combined Facilities As outlined above, several factors influence our ability to mine bitcoin profitably, including bitcoin’s USD value, mining difficulty, global hashrate, power costs, fleet energy efficiency, and overall data center efficiency.
Bitcoin Mining - Share of Global Hashrate Several factors influence our ability to mine bitcoin profitably, including bitcoin’s USD value, mining difficulty, global hashrate, power costs, fleet energy efficiency, and overall data center efficiency. Among these, energy efficiency is a critical driver of profitability, as power costs represent the most significant direct expense in bitcoin mining.
During the year ended December 31, 2024, the Company recorded an accelerated depreciation expense of $5.1 million related to certain miners whose estimated useful lives were shortened due to planned replacement by April 2024. While our standard depreciation period for miners is four years, historically low power costs may allow for a longer actual useful life in certain cases.
While our standard depreciation period for miners is four years, historically low power costs may allow for a longer actual useful life in certain cases. However, if depreciation were included in the cost of mining analysis, it would add $41,930 and $22,086 per bitcoin mined for the years ended December 31, 2025 and 2024, respectively.
In addition, the average price of bitcoin increased during the year ended December 31, 2024 to $65,824 as compared to $28,788 during the same period in the prior year, resulting in an increase in revenue of $70.9 million.
Digital asset revenue for the years ended December 31, 2025 and 2024 was $151.6 million and $140.1 million, respectively, an increase of $11.5 million. The increase was primarily attributed to an increase in the average price of bitcoin during the year ended December 31, 2025 of $101,658 as compared to $65,824 during 2024.
Digital currency Digital currency is comprised of bitcoin earned as noncash consideration in exchange for providing hash computation services to a mining pool as well as consideration for bitcoin miner hosting services. From time to time, the Company also receives bitcoin as distributions-in-kind from its joint venture.
These costs are passed through to the customers, generally with a mark-up, and, in accordance with U.S. GAAP, are included in the Company’s HPC lease revenue. Digital assets Digital assets is comprised of bitcoin earned as noncash consideration in exchange for providing hash computation services to a mining pool as well as consideration for bitcoin miner hosting services.
Its strategic location and access to low-cost, predominantly zero-carbon energy make it a highly attractive site for both bitcoin mining and HPC workloads.

Bitcoin Mining Operations As of December 31, 2025, we owned approximately 54,100 miners, with approximately 49,400 operational at our bitcoin mining facilities on the Lake Mariner Data Campus (the “LMD Bitcoin Mining Facilities”) and the remainder 28 Table of Contents undergoing maintenance, awaiting disposal or on standby to replace miners under repair.
However, if depreciation were included in the cost of mining analysis, it would add $22,086 and $9,892 per bitcoin mined for the years ended December 31, 2024 and 2023, respectively. Estimating asset useful lives requires management judgment, particularly given the rapid evolution of next-generation mining rigs in industrial-scale bitcoin mining.
Estimating asset useful lives requires management judgment, particularly given the rapid evolution of next-generation mining rigs in industrial-scale bitcoin mining. Depreciation schedules may be adjusted if events, regulatory changes, or shifts in operating conditions indicate a need for revision.
The decrease in interest expense during the year ended December 31, 2024 as compared to the prior year is primarily due to early repayments of the Term Loans principal balance resulting in a decrease of amortization of debt issuance costs and debt discount of $8.1 million.
The increase is primarily attributed to the proceeds from issuance of long-term debt and convertible notes, net of issuance costs paid, of $5,106.7 million for the year ended December 31, 2025 as compared to $487.1 million in the prior year.
Power prices increased during the year ended December 31, 2024 as compared to prior year and cost of revenue (exclusive of depreciation) increased approximately $35.3 million for the year ended December 31, 2024 as compared to the prior year primarily due to the increase in mining capacity and the halving in April 2024.
While the Company continued to profitably mine bitcoin during the year ended December 31, 2025, the Company reported $10.9 million lower digital asset segment profit as compared to the prior year primarily due to the halving in April 2024 and the increase in network hashrate as compared to prior year.

Cost of revenues is primarily comprised of power expense and the increase was primarily due to the increase in mining capacity due to infrastructure constructed and placed in service between December 31, 2023 and December 31, 2024 at the Lake Mariner Facility and, to a lesser extent, an increase in realized power prices during the year ended December 31, 2024 as compared to the same period in the prior year.
Cost of revenues is primarily comprised of power expense which increased for the year ended December 31, 2025 as compared to the year ended December 31, 2024, resulting from higher realized power prices during the 2025 period partially offset by higher proceeds from participation in demand response programs.
