We reissue comment two from our May 15, 2025 letter in part. We note that, on April 1, 2025, you announced the launch of an open season to solicit commitments from E&P companies to support your construction of a large diameter transportation pipeline, which you refer to as the "Speedway Pipeline," that will extend across the northern Delaware Basin and connect Eddy and Lea counties to out-of-basin pore space in the Central Basin Platform owned by LandBridge.
