Customers

Strategy
Williams focuses on maximizing utilization of its contracted pipeline and midstream assets by serving large, growing U.S. supply basins and demand markets. Its strategy emphasizes long-term firm transportation and processing contracts, selective growth projects, and maintaining safe, reliable operations across its network.
Long-term firm contracts support utilization and reduce volume risk.
Pipeline and processing uptime are central to customer retention and regulatory compliance.
A diversified network across gathering, transmission, storage, and marketing improves access to multiple demand centers.
Geography
Williams’ operations are concentrated in the United States, with assets in 24 states and the Gulf of America. Its headquarters are in Tulsa, Oklahoma, with other major offices in Houston, Pittsburgh, and Salt Lake City, and its pipeline and processing footprint is tied to major U.S. supply basins and demand centers.
Risks
Williams is exposed to regulatory, environmental, commodity, and counterparty risks that are common in regulated midstream infrastructure. Its earnings can also be affected by project permitting, construction execution, cybersecurity threats, and changes in natural gas supply and demand across the basins it serves.
