Bitfarms Reports Third Quarter 2025 Results

- Revenue of $69 million from continuing operations and $14 million from discontinued operations -

- Successfully closed $588 million convertible notes offering -

- Announced plans to convert Washington site to support GB300s with advanced liquid cooling -

Toronto, Ontario and New York, New York (November 13, 2025) - Bitfarms Ltd. (Nasdaq/TSX: BITF), a North American energy and digital infrastructure company, today reported its financial results for the third quarter ended September 30, 2025. All financial references are in U.S. dollars.

“We continue to execute on our strategy to pivot from an international Bitcoin miner to a North American energy and digital infrastructure company,” stated CEO Ben Gagnon. “We recently announced our successful $588 million convertible note offering, alongside our plans to convert our Washington site to HPC/AI workloads where additional monetization strategies for the site, including cloud operations, are being evaluated. Beyond Washington, everything in our portfolio is being built to support Nvidia’s next generation Vera Rubin GPUs which are expected to ship in Q4 2026. With almost twice the energy density of Nvidia’s Blackwell GPUs, there is not a data center that exists today that can support Nvidia’s next generation of AI hardware.”

Gagnon continued, “While most developers are focused on supporting Blackwells we intend to lead the industry in the development of Vera Rubin infrastructure. We strongly believe this infrastructure will be in even higher demand and shorter supply in 2027 and will command substantially greater economics from prospective customers. With our strong financial position and high-value energy portfolio, Bitfarms has never been better positioned to build the infrastructure that will power tomorrow’s economy.”

CFO Jonathan Mir stated, “With the successful completion of our $588 million convertible note offering and the conversion of our $300 million Macquarie debt facility to a project-specific financing for the development of our Panther Creek campus, the company is excited to commence the initial phases of our HPC/AI development, including civil works, substation works, and deposits on long-lead time items, at our Washington, Panther Creek, and Sharon sites. We now have substantial financial flexibility with $814 million in liquidity** as of November 12, 2025 and an additional $200 million potentially available from the Macquarie facility, and we have a clear vision of how we’re going to best utilize these funds to advance our HPC/AI infrastructure build outs across North America.”

HPC / AI Infrastructure Projects

●

Announced plans for conversion of the Washington site to HPC/AI workloads, targeting completion as early as December 2026. The site will feature validated reference designs compatible with GB300 GPUs, modular infrastructure for phased deployment and faster scalability, and state-of-the-art liquid cooling. Bitfarms signed a fully binding agreement for $128 million to supply all of the critical IT equipment and building materials for 18 MW of gross capacity.

●

Received positive indications from PPL on viability of converting Panther Creek’s existing ISA of 60 MW to a firm ESA of 60 MW to expand the provision of firm power to 410 MW with the potential to expand power capacity to over 500 MW, based on an additional load study.

●

Completed acquisition of Sharon, Pennsylvania property, previously operating under a 17-year lease. The campus is currently operating 30 MW of Bitcoin mining capacity, which will now be committed to HPC/AI infrastructure. An additional 80 MW substation is expected to come online by year-end 2026, bringing the anticipated total to 110 MW.

●

Converted previously announced Macquarie credit facility for up to $300 million to an up to $300 million project-specific financing facility for the development of Panther Creek, Pennsylvania campus and drew an additional $50 million from the converted facility to accelerate long-lead-time equipment purchases and advance HPC/AI development at this campus.

Executive Team Updates, Corporate Initiatives & U.S. Pivot

●

Announced the retirement of Jeffrey Lucas, Chief Financial Officer, and the appointment of Jonathan Mir, a global financial and strategic executive with over 25 years of capital markets experience in energy infrastructure, as successor effective October 27, 2025.

●

Appointed former Amazon Web Services executive Wayne Duso to Board of Directors effective August 18, 2025.

●

Commenced corporate share buyback program under which the Company is authorized to purchase up to 10% of the Company’s public float during the period starting on July 28, 2025 and ending on July 27, 2026. Purchased 7.8 million shares to-date at an average price of $1.27 for a total of approximately $10 million.

●

Announced second Principal Executive Office in NYC and commitment to convert to U.S. GAAP by year-end 2025 as part of broader strategy to redomicile to the U.S.

●

Discontinued the Argentina and the Paraguay operations, reflecting the strategic shift to North American HPC/AI infrastructure projects. In Q3 2025, total revenue from discontinued operations was $14 million, and net loss was $35 million, including impairment charge of $34 million mainly resulting from the reclassification of the Paraguay operations’ assets, which required these to be measured at fair value less costs to sell.

Power Portfolio & Mining Operations

●

Updated energy portfolio consists of 2.1 GW of power infrastructure assets in the U.S. and Canada, including 341 MW of energized capacity, 440 MW of secured contracted growth capacity, and 1,360 MW of capacity under application.

●

Mining fleet remains efficient at 18 installed Watts/TH and continues to generate cash flow.

●

Net loss of $46 million, or $0.08 loss per basic and diluted share, compared to a net loss of $24 million, or $0.05 loss per basic and diluted share, in Q3 2024
