• Successful addition of a fifth Drilling Spacing Unit (DSU) in the SWISH Play
• Increases Brookside's high-quality, low-risk development drilling locations by 26%
• Planning underway to develop the new DSU with two horizontal wells targeting Sycamore and Woodford formations

Brookside Energy Limited has announced the successful addition of a fifth Drilling Spacing Unit (DSU) within its high-impact SWISH Play acreage in the Anadarko Basin, Oklahoma. The new 960-acre DSU is located adjacent to and contiguous with the Company's existing Jewell and Bruins DSUs, enhancing Brookside's core operated position in this highly sought-after area. This strategic addition increases the Company's inventory of high-quality, low-risk development drilling locations within the SWISH Play by approximately 26%. Initial acreage within the new DSU has been secured through Brookside's active and highly effective leasing program, targeting areas prospective for multiple stacked pay zones including the proven Sycamore-Woodford interval. The Company has also lodged initial regulatory filings with the Oklahoma Corporation Commission (OCC), establishing the spacing framework and laying the groundwork for future development. Planning is already underway to secure, design, and construct a multi-well, all-weather pad to support the efficient development of this new DSU. Once mandated, initial development is expected to consist of two horizontal wells with ~8,000-foot laterals--one targeting the Sycamore formation and one the Woodford Shale--drilled on a northwest diagonal trajectory. This plan mirrors the highly successful approach used by Continental Resources in the nearby Courbet and Gapstow DSUs and reflects Brookside's capital-efficient, dual-zone development strategy. The addition of this new DSU, alongside the growing prospectivity of the emerging Simpson Group and Caney Shale sub-plays, strengthens Brookside's strategic position within the SWISH Play and supports long-term optionality as the Company balances capital discipline with scalable development and capital returns.

Brookside is well positioned to deliver the next phase of value for shareholders with additional drilling inventory secured, new sub-play potential emerging, and preparations underway for its listing on the NYSE.
