LABOR MODERNIZATION: LEAN EMPOWERED FIELD 25 Revamping field operations through empowerment, accountability, and technology: Interview 100% of field staff using standardized evaluation process to retain top talent Flatten field structure with asset managers, techs (super pumpers), and pumpers for faster decisions Introduce digital tools to do more with less Launch field incentive plans aligning frontline performance with company goals ACQUISITION CASE STUDY 72% DAY 1 LABOR COST IMPROVEMENT Field Supervision (10) Pumpers (40) Contractors (13) Total (63) Field Supervision (0) Pumpers (16) Contractors (4) Total (20)

Pumpers focused only where value or risk existed PUMP-BY-EXCEPTION: TURNING DATA INTO FIELD ACTION 26 Old Route (27 wells) New Route (50 wells) HIGHER PRODUCTIVITY PUMPER STRATEGY Legacy: Daily visits to every well PBE: Visit top 20% of wells by cash flow every day and the rest only if alerted, resulting in 50% reduction in well visits FEWER PUMPERS High-priority wells surfaced automatically SMARTER ROUTES Routes adjusted dynamically based on real-time inputs Traditional well-visit schedules gave way to automated, exception-based system using machine learning and real-time alerting.

DEVELOPMENT: BRINGING VALUE FORWARD 30 Over $100MM in value realized since inception with zero capital risk. Flexible capital and operating structures allow Presidio to scale with partners and deliver growth without incremental overhead or risk. STRUCTURED JOINT VENTURES Built and executed JV frameworks where partners fund drilling programs and Presidio assumes operatorship post-development, supporting long-term efficiency and alignment. ACREAGE SALES Executed strategic acreage sales, including ~100k acres in the Cherokee formation, to realize value while retaining existing wells and further upside. OUTSOURCED DEVELOPMENT MANAGEMENT Successfully managed development programs funded and executed by partners, promoting timely project completion, reducing cost structure, and heightening operating standards. CASE STUDY FARM-OUT (CARRIED DEVELOPMENT PROGRAM) • Structured carry where partner funded and drilled initial wells and Presidio contributed acreage. • Presidio assumed operatorship upon completion. • Delivered low-cost transition and long-term cash flow alignment.
