About
Expand Energy Corporation is an Oklahoma City, Oklahoma-based natural gas exploration and production company — publicly traded on the NASDAQ (NASDAQ: EXE) — formed through the October 2024 merger of Chesapeake Energy Corporation and Southwestern Energy Company, creating the largest pure-play natural gas producer in the United States by volume with production exceeding 7.3 billion cubic feet per day equivalent (Bcfe/d) across the Appalachian Basin (Marcellus and Utica shale in Pennsylvania, West Virginia, and Ohio) and Mid-Continent (Haynesville shale in Louisiana and Texas). Chesapeake Energy rebranded as Expand Energy upon closing the $7.4 billion all-stock acquisition of Southwestern Energy, combining Chesapeake's Haynesville and Marcellus positions with Southwestern's dominant Appalachia and Haynesville footprint to create a company with 6,300 net wells, 1.6 million net acres across core natural gas basins, and estimated proved reserves exceeding 20 trillion cubic feet equivalent (Tcfe). CEO Domenic Dell'Osso leads Expand Energy's strategy of consolidating the US natural gas producer landscape to capture economies of scale in drilling operations, midstream contracting, and LNG export supply agreements — positioning the combined company as a reliable long-term supplier to US liquefied natural gas (LNG) export terminals that require 20-year take-or-pay supply commitments from creditworthy, large-scale gas producers. The Expand Energy name reflects the company's positioning around expanding US natural gas supply for LNG exports that serve Europe's energy security needs following Russia's reduction of pipeline gas supplies to the continent.
