MARA Holdings reports $1.7B quarterly deficit amid Bitcoin downturn
The cryptocurrency mining firm MARA disclosed a staggering $1.71 billion loss for the quarter, driven by Bitcoin fair-value adjustments, while simultaneously announcing an aggressive expansion into artificial intelligence and high-performance computing.
In a filing that underscored the volatility of cryptocurrency operations, MARA Holdings (MARA) disclosed a fourth quarter 2025 net deficit totaling $1.71 billion, translating to $4.52 per diluted share. This stands in stark contrast to the same quarter one year prior, when the company generated net income of $528.3 million, equivalent to $1.24 per diluted share.
According to the shareholder communication submitted to the US Securities and Exchange Commission (SEC), the company's Q4 revenue experienced a 6% decline to $202.3 million from $214.4 million recorded in Q4 of 2024. This decrease occurred as declining average Bitcoin (BTC) valuations offset gains achieved through increased hashrate capacity.
When examining the complete 2025 fiscal year, Marathon recorded a net deficit of $1.31 billion, a dramatic reversal from the $541 million net income achieved in 2024. This occurred despite the company's revenue climbing to $907.1 million from $656.4 million during the previous year.
The organization explained that its Q4 net income suffered from a substantial $1.50 billion adverse adjustment in the fair value of digital assets and digital assets receivable. This markdown mirrors Bitcoin's price trajectory, which tumbled from approximately $114,300 on Sept. 30 to roughly $88,800 on Dec. 31, based on figures from CoinGecko.
Shareholders have also experienced significant pain, with MARA stock plummeting 46% over the preceding six-month period.
From a production perspective, Marathon disclosed that it successfully mined 2,011 BTC during Q4 2025, representing a 6% decrease from the 2,144 BTC produced in the previous quarter and the 2,492 BTC generated during the corresponding period one year earlier. For the entire year, the company mined 8,799 BTC, compared with 9,430 BTC in 2024.
The firm indicated that it concluded 2025 with holdings of 53,822 BTC, which includes 15,315 BTC that has been loaned or pledged as collateral. The company's balance sheet Bitcoin was assessed at approximately $4.7 billion using a quarter-end spot price of $87,498 per coin.
Marathon's AI and high-performance compute push
Beyond the financial metrics, Marathon utilized its Q4 shareholder communication to unveil a multi-year transformation "from a pure-play Bitcoin miner into an energy and digital infrastructure company." The announcement included details of a strategic joint venture with Starwood Digital Ventures focused on developing artificial intelligence (AI) and high-performance compute (HPC) data centers at its energy-abundant locations.
Marathon explained that the Starwood collaboration was structured to accommodate more than 1 gigawatt of IT capacity during its initial phase. The roadmap envisions potential expansion exceeding 2.5 gigawatts over time, while providing Marathon with the flexibility to invest up to 50% in individual projects. The company plans to continue Bitcoin mining operations where electricity costs remain favorable.
The organization also drew attention to its February acquisition of a 64% ownership stake in Exaion, aimed at targeting "sovereign-grade" and enterprise AI implementations.
Miners diverge on strategy as drawdown bites
Marathon's hybrid operational approach emerges as other prominent mining operations continue exploring different strategic playbooks in reaction to the most recent Bitcoin price correction.
Hut 8 disclosed a fourth-quarter net deficit of $279.7 million on Wednesday, as the company pivots toward a $7 billion AI data center lease arrangement, while Trump-backed American Bitcoin announced a $59.5 million Q4 2025 loss on Thursday, yet remains committed to its mine-and-hoard BTC strategy.
