Consolidation Nation: Just 40 Companies Produce 41% of U.S. O&G

EY, previously known as Ernst & Young, is a multinational professional services network (i.e., consulting firm) based in London. EY is also one of the "big four" largest accounting firms in the world. EY published a new study last week titled "US Oil and Gas Reserves, Production and ESG Benchmarking Study" (full copy below). The study found that due to mergers and acquisitions in 2024, the largest publicly traded oil and gas companies in the U.S. went from 50 down to 40, and that those 40 companies produced a staggering 41% of all O&G production in this country. It's probably no surprise that many in the list produce natural gas (and oil) in the Marcellus/Utica.
