Beyond the financial results, MARA disclosed a newly authorized $500 million share repurchase program, the repayment of $750 million in bitcoin-backed loans following the quarter's end, and progress toward securing its first major AI data center leases.
The company is targeting two lease signings before the end of 2026, although management acknowledged that the timeline could slip into next year.
The results illustrate the increasingly complex financial profile of one of the world's largest publicly traded bitcoin miners as it seeks to transform its portfolio of powered infrastructure into a business serving both digital mining and AI computing customers.
Bitcoin Gains Drive Profit Despite Lower Revenue
MARA's reported earnings were heavily influenced by the accounting treatment of its bitcoin holdings.
The company recognized approximately $885.3 million in combined fair-value gains on digital assets and digital asset receivables during the third quarter, compared with approximately $343.1 million a year earlier.
The increase helped lift reported net income to $632.1 million, equivalent to $1.28 per diluted share, despite declining revenue from mining operations.
The company reported a $611.3 million net loss in the preceding quarter, when falling bitcoin prices weighed on the valuation of its holdings.
As TheEnergyMag previously reported, MARA's second-quarter results demonstrated the substantial impact that cryptocurrency price movements can have on reported profitability.
The latest quarter shows the reverse effect.
Although MARA reported higher net income and adjusted EBITDA, those figures should not be interpreted as evidence of a comparable improvement in underlying mining economics or operating cash flow.
In fact, the company attributed most of its revenue decline to a 37% reduction in the average bitcoin price realized for production revenue compared with the prior-year period.
Lower prices reduced mining revenue by approximately $94.8 million, partially offset by an $11.7 million benefit from increased production.
The distinction is particularly relevant as investors assess whether MARA's traditional mining business can generate sufficient cash to support its expansion into capital-intensive AI infrastructure.
Mining Output Rises, but Network Competition Weighs on Economics
MARA produced 2,247 BTC during the third quarter, up 5% from 2,144 BTC a year earlier but down 7% from 2,422 BTC in the second quarter.
The company's energized hashrate increased 18% year-over-year to 71.2 exahashes per second (EH/s), reflecting continued improvements in mining equipment efficiency.
Despite the increase in installed computing capacity, MARA's share of available bitcoin mining rewards declined sequentially to 5.4% from 5.9%, underscoring the effects of network competition and operational conditions.
The company won 644 blocks during the quarter, compared with 700 in the preceding three months.
At its owned facilities, average electricity costs remained approximately $0.04 per kilowatt-hour.
Purchased electricity costs per bitcoin produced reached $39,674, compared with $39,235 a year earlier.
MARA attributed the increase to higher electricity expenses and growth in global network difficulty that outpaced its hashrate expansion.
That figure measures purchased electricity costs at owned and operated mining sites, not the company's fully loaded cost of producing bitcoin. It excludes other expenses such as depreciation and corporate overhead.
The company said it would continue selectively modernizing its mining fleet while evaluating whether individual sites could generate higher risk-adjusted returns from AI and high-performance computing customers.
MARA Sells $1.1 Billion in Bitcoin, Repays $750 Million in Loans
MARA also provided a significant update on its bitcoin treasury strategy and balance sheet.
At September 30, the company held 34,012 BTC, valued at approximately $2.8 billion, alongside $946.5 million in cash and cash equivalents.
The combined value of cash and bitcoin holdings was approximately $3.8 billion.
Of the bitcoin total, 19,260 BTC were loaned or pledged as collateral, representing approximately 57% of holdings at quarter-end.
Following the quarter's close, MARA sold 13,597 BTC at an average price of approximately $81,039, generating roughly $1.1 billion in proceeds.
The company used $750 million to fully repay its outstanding bitcoin-collateralized term loans, releasing 17,477 BTC previously pledged as collateral.
MARA said it had reduced total debt by $1.4 billion, or approximately 37%, since the beginning of the year.
The latest transactions reflect a notable evolution in its treasury strategy.
Historically associated with accumulating mined bitcoin, MARA has increasingly treated its holdings as a source of capital for infrastructure acquisitions, debt reduction and other corporate priorities.
The company indicated that additional bitcoin sales could support future AI infrastructure investments, convertible debt obligations and potential share repurchases.
That approach provides financial flexibility but also reduces the company's direct exposure to future bitcoin price appreciation as holdings are monetized.
$500 Million Share Buyback Authorized
MARA's board also authorized a share repurchase program of up to $500 million following the end of the third quarter.
The company said repurchases could occur through open-market purchases, privately negotiated transactions or other permitted methods.
The authorization does not require MARA to purchase any specific number of shares, and the program can be modified or suspended depending on market conditions and capital needs.
The decision comes as MARA balances several competing uses of capital, including reducing debt, developing data centers and acquiring electricity infrastructure.
The company has also continued raising equity capital. It reported approximately $1.5 billion in remaining capacity under its at-the-market equity offering program as of September 30.
The potential coexistence of share repurchases and future equity issuance illustrates the flexibility MARA is seeking in its capital allocation strategy, although the company has not committed to executing either at a particular pace.
Two AI Data Center Leases Targeted Before Year-End
On the infrastructure side, MARA said discussions with prospective AI and high-performance computing tenants have advanced across multiple sites.
Management is targeting the signing of two data center leases before year-end, while acknowledging that market conditions could push execution into 2027.
The company highlighted progress at its Kearney campus in Nebraska, where pre-development work is well advanced.
MARA is pursuing the projects through its strategic partnership with Starwood Capital Group and Starwood Digital Ventures, announced in February.
The partnership is intended to convert selected bitcoin mining properties into AI-capable data center campuses, combining MARA's power and land portfolio with Starwood's development, financing and leasing capabilities.
As TheEnergyMag previously reported, the partners initially outlined a pathway to more than 2.5 GW of potential AI infrastructure capacity.
However, MARA has not announced executed leases covering the two agreements it currently hopes to sign.
The company said customers and lenders are applying greater scrutiny to site readiness, construction schedules, financing arrangements and contractual credit support.
Those requirements have become increasingly important as AI infrastructure developers face concerns about capital intensity and the ability to bring large projects online on schedule.
For MARA, the next milestone is converting its portfolio of powered sites into binding agreements with customers capable of supporting project financing.
Long Ridge Acquisition Nears Closing After FERC Approval
MARA also outlined progress on its planned acquisition of Long Ridge Energy & Power in Ohio.
The company received approval from the Federal Energy Regulatory Commission last week and expects to complete the transaction before year-end, subject to remaining conditions.
The acquisition includes a natural gas-fired power plant with 505 MW of nameplate capacity, more than 1,600 contiguous acres of land, and access to water, fiber and rail infrastructure.
The plant is currently authorized to sell 485 MW, with an increase to its full nameplate capacity expected in the first half of 2027.
Approximately 70% of its output is supported by long-term contracts, according to MARA.
As TheEnergyMag reported last week, the acquisition is valued at approximately $1.5 billion, including assumed debt, and represents a significant step beyond MARA's traditional bitcoin mining operations.
The site could eventually support a large AI data center campus alongside the existing mining operations, with MARA describing more than 1 GW of total potential capacity at Long Ridge.
That figure remains a development opportunity rather than operating AI data center capacity.
The company is also advancing its Matagorda County project in Texas, which has potential access to up to 2 GW of electricity.
The site received a provisional "Studied Load" classification under ERCOT's Batch Zero process, meaning its requested capacity remains subject to additional studies and allocation.
MARA previously restructured the project's acquisition terms to link payments more closely to regulatory approvals and development milestones.
The company said it has not made payments to the sellers under the contingent acquisition arrangements.
Together, the projects form part of MARA's stated pathway from approximately 1.9 GW of energized capacity across its broader portfolio toward a potential 4.8 GW footprint.
That longer-term figure depends on acquisitions, grid approvals and further infrastructure development. It should not be interpreted as electricity already available for new AI tenants.
Exaion Signs $79 Million GPU Cloud Contract
MARA's expansion beyond powered land and colocation infrastructure is also gaining traction through Exaion, its majority-owned AI and private cloud business.
The company disclosed that Exaion recently signed a four-year, $79 million GPU-as-a-service agreement with its first U.S. customer.
The agreement operates on 100% take-or-pay terms, requiring the customer to pay for the contracted capacity regardless of utilization.
MARA said Exaion has also developed a pipeline representing more than $3 billion in potential contract value, with approximately $1 billion of prospective business targeted for delivery by the end of 2027.
That pipeline is not contracted revenue or backlog.
Prospective customers have expressed demand for more than 30 MW of computing capacity during the same period, according to the company.
Exaion provides private cloud infrastructure, GPU computing and AI inference services, particularly for enterprise customers with data sovereignty and security requirements.
The business gives MARA potential exposure to higher-value computing services rather than solely collecting rent from data center tenants.
However, the $79 million contract remains an early commercial milestone relative to the broader development pipeline.
From Bitcoin Mining to an Energy-Backed Compute Platform
MARA's third-quarter results highlight the financial and operational challenges of combining a large bitcoin mining fleet with an emerging AI infrastructure business.
Its legacy mining operations remain the company's principal source of operating revenue, while its reported quarterly profitability continues to fluctuate substantially with bitcoin valuations.
At the same time, MARA is using its mining experience, power portfolio and bitcoin treasury to pursue a different long-term business model built around electricity generation, data center development and enterprise computing services.
The strategy has produced tangible progress, including the Long Ridge regulatory approval, an initial Exaion customer contract and debt reduction funded by bitcoin sales.
But several of the most consequential milestones remain ahead.
The proposed AI leases have not been signed, Long Ridge has not yet closed, and Matagorda's grid capacity remains subject to regulatory and utility decisions.
For investors, the next tests will be whether MARA can convert those development opportunities into financeable long-term contracts, deliver infrastructure on schedule and generate recurring cash flow less dependent on bitcoin price movements.
