• WhiteHawk, through its affiliate, entered into a definitive purchase and sale agreement to acquire natural gas mineral and royalty assets covering 150,000 gross unit acres in the core of the Haynesville Shale
• The assets to be acquired include approximately 500 producing natural gas wells and approximately 1,000 wells-in-process, permitted wells, and undeveloped locations

WhiteHawk Energy, LLC (“WhiteHawk” or the “Company”) announced today that its affiliate entered into a definitive purchase and sale agreement to acquire natural gas mineral and royalty interests primarily located in the core of the Haynesville Shale in Louisiana and east Texas (“Haynesville Assets”). The Haynesville Assets cover approximately 150,000 gross unit acres and further increase WhiteHawk’s exposure to high-quality development across the Haynesville and Mid-Bossier formations. The assets are concentrated in core areas of the basin and are operated by established, well-capitalized operators. The Haynesville Assets acquisition is expected to close in early April 2026.

The Haynesville Assets are supported by meaningful existing production and visible near-term development activity, complemented by a substantial inventory of undeveloped drilling locations. Through the acquisition, WhiteHawk will increase its exposure to leading operators in the basin, including Expand Energy, Apex Energy, Aethon Energy Management (to be acquired by Mitsubishi), GeoSouthern Energy (to be acquired by JERA Co.), and EXCO Resources. The transaction is expected to further strengthen WhiteHawk’s position in one of North America’s most economic natural gas basins.

“We are pleased to expand our core Haynesville footprint through the acquisition of high-quality mineral and royalty interests, operated by top-tier natural gas producers,” said Daniel Herz, Chief Executive Officer of WhiteHawk Energy. “The Haynesville Assets will deepen our exposure to leading operators in Louisiana and Texas while adding scale in a basin that we believe will continue to play a critical role in meeting domestic and global natural gas demand with strategic proximity to LNG export terminals.”

After accounting for the acquisition of the Haynesville Assets, WhiteHawk will own natural gas mineral and royalty interests across 3.5 million gross unit acres, with over 11,000 producing wells, 500 wells-in-process and permitted wells, and 8,000 undeveloped locations. WhiteHawk continues to be focused on acquiring natural gas mineral and royalty interests focused in the core of the Marcellus Shale and the Haynesville Shale. Inclusive of the Haynesville Assets, the Company has added to its mineral and royalty positions through six acquisition transactions thus far in 2026. The Company remains focused on acquiring large-scale, cash-flowing mineral and royalty assets in premier natural gas basins and structuring transactions to support long-term value creation.
