SKN | MARA Swings to $1.7B Quarterly Loss as Bitcoin Slide Hits Balance Sheet

Key Points

• MARA reported a $1.71 billion net loss in Q4 2025 after a $1.5 billion fair-value markdown tied to Bitcoin’s price decline.
• Revenue slipped 6% year over year as lower BTC prices offset higher hashrate.
• The company outlined a strategic pivot toward AI and high-performance computing infrastructure alongside its core mining operations.

MARA Holdings posted a fourth-quarter 2025 net loss of $1.71 billion, or $4.52 per diluted share, reversing sharply from net income of $528.3 million a year earlier.

The loss was largely driven by a $1.5 billion negative fair-value adjustment on digital assets and receivables. During the quarter, Bitcoin fell from roughly $114,300 at the end of September to about $88,800 by Dec. 31.

Revenue declined 6% year over year to $202.3 million, as weaker average BTC prices outweighed the benefit of increased mining capacity.

For full-year 2025, MARA reported a net loss of $1.31 billion despite revenue rising to $907.1 million from $656.4 million in 2024 — underscoring the volatility introduced by mark-to-market accounting.

The stock has fallen 46% over the past six months amid the broader crypto downturn.

Mining Output Slows

Operationally, MARA mined 2,011 BTC in Q4, down from 2,144 in the prior quarter and 2,492 in the same period a year earlier. For the full year, production totaled 8,799 BTC compared with 9,430 BTC in 2024.

The company ended 2025 holding 53,822 BTC, including 15,315 coins that were loaned or pledged as collateral. At a quarter-end spot price of $87,498 per bitcoin, the firm valued its BTC holdings at approximately $4.7 billion.

Strategic Shift Toward AI and HPC

Beyond the earnings numbers, MARA used its shareholder letter to signal a longer-term transformation.

The company announced a joint venture with Starwood Digital Ventures aimed at building artificial intelligence and high-performance computing (HPC) data centers at power-rich mining sites.

The partnership is designed to support more than 1 gigawatt of IT capacity initially, with potential expansion beyond 2.5 gigawatts. MARA retains the option to invest up to 50% in individual projects while continuing bitcoin mining operations where economics remain favorable.

In February, the firm also acquired a 64% stake in Exaion to target enterprise and sovereign-grade AI deployments.

The pivot reflects a broader industry trend: miners are increasingly leveraging their access to large-scale energy infrastructure to diversify into compute services as bitcoin mining margins compress.

Diverging Miner Playbooks

MARA’s hybrid mining-and-AI strategy contrasts with other approaches across the sector.

Hut 8 recently reported a $279.7 million quarterly loss while pursuing a $7 billion AI data center lease strategy. Meanwhile, Trump-backed American Bitcoin continues emphasizing a mine-and-hold BTC treasury model despite reporting losses of its own.

As bitcoin’s price volatility pressures balance sheets, miners are increasingly experimenting with diversified infrastructure plays to stabilize revenue streams.

For MARA, the $1.7 billion quarterly loss underscores the risks of holding large bitcoin reserves under fair-value accounting — but its AI pivot suggests the company is betting that compute demand, not just crypto cycles, will define its next growth phase.
