The Williams Companies, Inc. (WMB) is a leading U.S. energy infrastructure company headquartered in Tulsa, Oklahoma. It primarily operates natural-gas pipelines and processing facilities, transporting and processing natural gas across the country. With a market cap of $74.4 billion, the company owns and operates midstream gathering and processing assets and interstate natural gas pipelines.
Companies worth $10 billion or more are generally described as “large-cap stocks,” and WMB perfectly fits that description, with its market cap exceeding this mark, underscoring its size, influence, and dominance within the oil & gas midstream industry. As a major midstream operator, Williams plays a key role in supplying natural gas for power generation, heating, and industrial use, with a business model that generates stable, fee-based revenue and lower exposure to commodity-price volatility.
