RANGE RESOURCES CORP

Our natural gas, NGLs and oil operations are concentrated in the Appalachian region of the United States, and more specifically, in the Marcellus Shale in Pennsylvania. Our properties consist of interests in developed and undeveloped natural gas, NGLs and oil leases. These interests entitle us to drill for and produce natural gas, NGLs and oil from specific areas. Our interests are mostly in the form of working interests and, to a lesser extent, royalty and overriding royalty interests.

We hold a large portfolio of drilling opportunities beyond the five-year horizon of proved reserves and therefore a significant unbooked resource potential within the Marcellus, Utica/Point Pleasant and Upper Devonian formations. We own 1,577 gross (1,499 net) producing gas wells in Pennsylvania, almost all of which we operate. Our average working interest in this region is 95%. We do not have any dual completions. As of December 31, 2025, we have approximately 879,000 gross (769,000 net) acres under lease in the Marcellus. During 2025, we averaged approximately two horizontal drilling rigs in the field and expect to have less drilling activity throughout 2026, while completions activity is expected to increase. Substantially all of our reserves and production are located in the Marcellus Shale.
