Nick Dell’Osso, Gulfport’s President and CEO, commented, “During the second quarter, we continued to execute on our development plan while taking meaningful steps to enhance the depth of our inventory with the addition of top-tier locations. Through the Ohio state land lease acquisition, we expanded our core Utica position with highly productive, liquids-rich wet gas acreage that represents some of the highest-return opportunities in our portfolio and integrates seamlessly into our near-term development plan. Building on this momentum, our land team continues to identify and negotiate attractive opportunities to expand our leading Ohio natural gas inventory through disciplined, targeted leasing. We expect to allocate approximately $140 million toward additional targeted discretionary acquisitions through year-end 2026, focusing on opportunities that enhance our core position, drive capital-efficient returns and further strengthen the long-term value and durability of our asset base.” Dell’Osso continued, “Our Utica and Marcellus development programs continue to deliver, highlighted by early results from our latest Marcellus pad that have exceeded expectations. Brought online under disciplined choke management, the pad is achieving stronger oil recoveries than nearby offset wells, supported by longer laterals and improved drilling efficiencies. These advancements are driving enhanced well-level economics and greater capital efficiency. Additionally, with two wet gas Utica pads recently completed near our Ohio state land lease acquisition, we anticipate a meaningful increase in liquids production during the second half of the year, positioning us to capture strong adjusted free cash flow in the current commodity price environment. With a significant portion of our 2026 capital program now complete, we expect full-year base capital expenditures to total approximately $430 million, including $35 million for maintenance land and seismic investments.” “Looking ahead, our priorities are clear: continue to improve capital efficiency across the business to reduce our breakevens and reinvestment rate, expand our inventory through disciplined and value-accretive acreage additions, preserve balance sheet strength and return excess cash to shareholders. We will continue to evaluate our capital allocation opportunities competitively and seek the optimal balance between strategic inventory expansion and opportunistic share repurchases, with each decision guided by returns, market conditions and our financial position. We remain committed to maintaining a conservative mid-cycle leverage profile and believe we are well positioned to build net asset value and deliver durable, long-term returns for our shareholders,” Dell’Osso concluded.
