Expands MARA's digital infrastructure platform with access to approximately 2 GW of power capacity

HIF to retain minority ownership in the project

Thousands of jobs expected for Texas

MIAMI, FL and HOUSTON, TX, July 09, 2026 (GLOBE NEWSWIRE) -- MARA Holdings, Inc. (NASDAQ:MARA) ("MARA"), a leading energy and digital infrastructure company, and HIF USA LLC ("HIF"), a leading energy and sustainable fuels company, today announced that they have entered into a definitive agreement under which MARA will acquire from HIF a large-scale powered land site in Matagorda County, Texas, approximately 90 miles southwest of Houston. HIF will continue its advanced fuels development plans on other sites.

The site encompasses more than 1,200 acres and is expected to provide access to up to an initial 1 GW of grid capacity by October 2027 and up to 2 GW by April 2028. The site is well positioned to support next-generation, efficient digital infrastructure development, and has already received interest from potential High-Performance Computing ("HPC") tenants. MARA intends to develop the site through its previously announced partnership with Starwood Digital Ventures as a large-scale digital infrastructure campus capable of supporting high-performance computing workloads, as well as flexible compute operations, including Bitcoin mining. Upon execution of a lease with an HPC tenant, HIF will retain a minority ownership interest in the project.

The transaction enables HIF to unlock value from infrastructure assets while maintaining participation in the site’s future development and supporting its broader advanced fuels strategy.

Upon full energization, the site is expected to more than double MARA's potential power capacity to approximately 4.8 GW across its portfolio (including the anticipated close of MARA’s previously announced agreement to acquire Long Ridge Energy & Power), further strengthening MARA's position as a developer and operator of large-scale digital infrastructure.

"This transaction advances our strategy of securing strategically located infrastructure assets capable of supporting high-performance compute and bitcoin workloads," said Fred Thiel, MARA's chairman and CEO. "As demand for digital infrastructure continues to grow, we believe sites with access to reliable, scalable power will become increasingly valuable. This acquisition meaningfully expands our long-term development pipeline and strengthens our ability to support high-performance compute and maximize the value of that power over time. We look forward to working with our partners at the site to deliver on the project buildout and drive long-term value for all our stakeholders."

Renato Pereira, CEO of HIF USA, said, "We are pleased to welcome MARA to our long-term partnership with Matagorda County, accelerating our commitment to economic investment and jobs for Texans. The development of this digital infrastructure serves as a powerful economic anchor to strengthen Matagorda County and create local career opportunities for a prosperous future. We have given Notice to Proceed for construction on the switchyard to connect the site to the grid. We continue work on our advanced fuels facilities on other sites we control in Texas and worldwide to provide new sources of secure energy supply to meet rapidly growing global demand."

Site Development Details

Phased construction of the digital infrastructure campus is expected to begin in 2026, contingent upon regulatory approvals.

By combining MARA's expertise in securing and managing large-scale power loads, Starwood Digital Ventures' world-class experience developing and operating data centers, and HIF's history in Matagorda, MARA believes the site is well positioned to support future digital infrastructure opportunities and create long-term value for customers, local communities, and shareholders.

MARA has a proven track record of investing in the communities where it operates while supporting grid reliability and local economic growth. To date, MARA has invested more than $1.2 billion in Texas. MARA intends to continue investing significantly to develop a premier digital infrastructure campus that is expected to support thousands of construction and permanent full-time jobs upon completion.
