MARA Holdings Inc. has reported a staggering net loss of $1.7 billion for the fourth quarter (Q4) of 2025, a stark contrast to the $528 million profit achieved in the same period the previous year.
This disclosure follows closely on the heels of a strategic alliance formed with Barry Sternlichtβs Starwood Capital Group, which aims to enhance the company’s infrastructure efforts.
The significant financial downturn coincides with a notable decline in Bitcoin’s value, which dropped nearly 30% during the quarter. As a result, MARA was compelled to account for a $1.5 billion non-cash fair value write-down in its cryptocurrency holdings.
- Quarterly revenue decreased by 6% year-on-year, totaling $202.3 million, down from $214.4 million in Q4 2024.
- Adjusted EBITDA fell sharply to negative $1.49 billion, contrasting with a positive $796 million recorded in the same quarter one year prior.
- For the entirety of 2025, the company faced a net loss of $1.3 billion, a significant drop from the net income of $541 million reported in 2024.
The implications of mark-to-market accounting practices have become increasingly evident, revealing how they can intensify fluctuations in the value of substantial Bitcoin reserves. Despite this setback, MARA’s balance sheet still boasts 53,822 BTC, reflecting a 20% increase from the previous year.
At the close of the year, Bitcoin, valued at around $87,498, gave MARA’s holdings an estimated worth of $4.7 billion. This total includes:
- 38,507 BTC classified as unrestricted,
- 9,377 BTC loaned out, and
- 5,938 BTC pledged as collateral.
Consequently, approximately 28% of their Bitcoin assets are currently encumbered. The company also reported generating $32.1 million in interest income through its lending activities over the year.
MARA’s liquidity remains robust, with around $5.3 billion in a combination of unrestricted cash and Bitcoin assets, including those that are loaned or pledged. Additionally, the company raised $568.6 million in 2025 using its at-the-market (ATM) program but paused this strategy in Q4, marking the first quarter since 2022 without its utilization.
From an operational perspective, the miner has continued to grow, achieving a record energized hashrate of 66.4 exahash per second (EH/s) in Q4, which represents a 25% increase year-on-year. However, this figure fell short of the 75 EH/s target that had been set, due to a focus on disciplined capital expenditures.
MARA’s Bitcoin production reached 2,011 BTC in the last quarter, reflecting a 6% decline from the previous year, influenced by increased network difficulty and seasonal energy challenges.
The cost of energy purchased per Bitcoin rose to $48,611 in Q4, while the cost per petahash per day improved by 4% to $30.5, indicating advancements in operational efficiency from the recent deployment of modern equipment.
Shifting focus, MARA is making a concerted effort to pivot toward energy and digital infrastructure, with a particular emphasis on AI and high-performance computing (HPC). This includes a joint venture with Starwood Digital Ventures aimed at establishing large-scale, enterprise, and AI-capable data centers.
The partnership is set to bring approximately 1 gigawatt (GW) of immediate IT capacity, with plans to expand beyond 2.5 GW in the future. MARA has the potential to invest up to 50% in these projects, which positions the company to achieve recurring revenue from infrastructure, thus lessening its reliance on Bitcoin price fluctuations.
Furthermore, MARA’s 64% stake in Exaion and the acquisition of a 42-megawatt data center in Nebraska are integral to its strategy in AI and HPC expansion.
Interestingly, MARA has modified its executive compensation structure in a recent 8-K filing, linking stock awards to megawatt capacity and contracted recurring revenue rather than being solely dependent on mining output. This adjustment also includes a change-of-control provision, ensuring that performance goals are considered met if the company undergoes a sale, a development that has sparked takeover speculation among investors.
Overall, MARA appears to be navigating the complexities of managing a vast Bitcoin treasury while simultaneously pursuing an ambitious infrastructure expansion plan. This strategy to diversify into energy and AI services may ultimately play a crucial role in reducing its earnings volatility in the next cryptocurrency market cycle.
