Bitcoin mining company MARA shifts focus to AI after $1.7 billion loss

Reshaping the direction of the business

The company recorded a massive net loss of $1.7 billion in the fourth quarter of 2025 – primarily due to a $1.5 billion decrease in the value of digital assets amid a 30% drop in Bitcoin prices during the quarter.

Despite disappointing earnings results and a 6% year-over-year drop in revenue to $202.3 million (below forecasts), the stock still surged 15-17% in after-hours and pre-market trading on February 26-27, as investors focused on the company's bold strategic shift toward artificial intelligence (AI) and high-performance computing (HPC) infrastructure.

This loss reversed a profit of $528 million from the same period the previous year, resulting in a full-year 2025 loss of $1.3 billion compared to previous year's earnings. Key factors include:

• The average price of Bitcoin obtained from mining has dropped sharply.

• Higher depreciation/amortization costs and an impairment loss of goodwill of $82.8 million.

• Mining output reached approximately 2,011 BTC in Q4 (down from the previous quarter), although the company ended the quarter holding 53,822 BTC (worth approximately $4.7 billion at closing prices , with about 28% pledged/loaned ).

However, the market's reaction was overwhelmingly positive, with MARA shares surging 17% in after-hours trading – reflecting a clear shift in investor attention from Bitcoin's short-term volatility to the company's rapid transformation into a digital energy and infrastructure business.

Joint venture with Starwood and the acquisition of Exaion

Alongside its earnings report, MARA announced a strategic joint venture with Starwood Capital Group ( through Starwood Digital Ventures ) to convert several energy-rich Bitcoin mining sites into AI/HPC-capable data centers.

• >1 gigawatt (GW) of IT capacity for AI, enterprise, and HPC workloads.

• Long-term roadmap: Aiming for >2.5 GW across the entire portfolio.

• Dual-use model: Facilities are designed to flexibly switch between Bitcoin mining and AI computing based on market economics and customer needs—maximizing profit per megawatt.

• Structure: MARA contributes the site and electricity access; Starwood leads the design, construction, and operation. Financial terms are not disclosed; MARA retains the option to purchase up to 50% of the shares.

This move follows MARA's earlier step in February 2026: acquiring a 64% stake in Exaion (a high-performance computing subsidiary originally owned by the French electricity company EDF ), adding to its national and enterprise-level artificial intelligence capabilities. CEO Fred Thiel emphasized:

“ Bitcoin remains a core pillar of MARA’s strategy, but we’re no longer simply a Bitcoin mining company. We’re building a vertically integrated energy and digital infrastructure company – leveraging our power certainty to create capacity certainty for the AI ​​era. ”

Impact on a small number of sectors

This significant drop in asset value isn't cash and is tied to the decline in Bitcoin's price—something many investors had anticipated . Bitcoin mining companies are holding scarce, cheap electricity in a world where AI data centers are facing severe energy constraints. Shifting to leasing electricity/capacity to AI/HPC clients provides a more stable and recurring revenue stream—separated from the volatility of BTC.

MARA is joining industry peers like Core Scientific (with hosting agreements with CoreWeave) and others in the transition " from Bitcoin mining company to AI infrastructure ." Access to electricity is currently a barrier—AI training/inference requires large and reliable power supplies, and mining companies already have sites with grid connections.

Building AI/HPC infrastructure requires partnerships, investment capital, and customer contracts. Bitcoin remains a cornerstone of the balance sheet (over 53,000 BTC), so a prolonged weakening of the cryptocurrency could put pressure on liquidity. Stocks are still down about 46% in six months and about 15-30% year-to-date amid weaker performance of mining companies in general.

Our review

The sharp drop in MARA in Q4 was driven by Bitcoin—but the market is betting on its resurgence. In a world where demand for AI computing far outpaces supply, a Bitcoin mining company's energy portfolio suddenly looks like a golden ticket. The 15-17% surge suggests investors are buying the story of a turnaround rather than the big losses in the headlines. Whether this is a true turning point or just another volatile chapter remains to be seen—but for now, energy + AI is the story driving MARA higher.
