About
ONEOK, Inc. is one of the largest midstream natural gas and liquid hydrocarbons infrastructure companies in the United States, founded in 1906 as Oklahoma Natural Gas Company in Tulsa, Oklahoma, where it remains headquartered and trades on NYSE (OKE). The company generated approximately $23.7 billion in revenues for FY2024 under CEO Pierce Norton, substantially transformed by the landmark September 2023 acquisition of Magellan Midstream Partners for approximately $18.8 billion—the largest U.S. midstream deal in years—which added approximately 9,800 miles of refined products pipelines and 54 petroleum product terminals, converting ONEOK from a primarily natural gas midstream company into a diversified midstream infrastructure operator spanning both natural gas (gathering, processing, transportation, storage) and refined petroleum products (pipelines, terminals, fractionation).
