Earthstone Energy, a growth-oriented, independent energy company, completed the acquisition of the northern Delaware Basin assets of OTPP and Warburg Pincus-backed Chisholm Energy, a privately held oil and gas company headquartered in Fort Worth, Texas, for $604m. "The Chisholm Acquisition caps off a series of highly-accretive and value-adding transactions that have dramatically transformed Earthstone during 2021 and further establishes Earthstone as a Permian Basin focused company with increasing scale. When this acquisition is combined with the previous four acquisitions completed in 2021, we will have increased our Permian Basin net acreage footprint by approximately 400%, almost tripled our daily production rate and meaningfully increased Free Cash Flow generation capacity," Robert J. Anderson, Earthstone President and CEO.
