• Exceptional early performance from Gapstow Wells in Oklahoma's SWISH Play
• Wells achieved average IP90 of 1,792 BOE per well, 73% liquids
• Significant cash flow to enhance Brookside's financial position

Brookside Energy Ltd has announced strong and sustained production results from its non-operated Gapstow Wells, located in Carter County, Oklahoma, within the core of the SWISH Play. Operated by major US oil and gas producer Continental Resources, the Gapstow Wells were drilled and completed in 2024, with production and first sales established late in the fourth quarter. Brookside holds a non-operated working interest in eight of the Gapstow Wells, representing a cumulative net revenue interest of approximately 16%. The Gapstow Wells have delivered exceptional early performance, producing nearly 1.65 million barrels of oil equivalent (~74% liquids) during their first three months of production (~27,500 BOE net to Brookside). The wells achieved an average IP90 (Initial Production over 90 days) of 1,792 BOE per well (normalized to 10,000' lateral), with 73% liquids content. These results further confirm the prolific nature of this part of the Anadarko Basin and the value of Brookside's strategic focus on the SWISH Play. The cash flow from these wells will significantly enhance Brookside's revenue base and working capital position, complementing its operated well portfolio.

Brookside looks forward to providing additional updates from its activities across its Anadarko Basin portfolio.
