Cigna primarily provides pharmacy benefit management and health insurance services. Its PBM and specialty pharmacy services, which were greatly expanded by its 2018 merger with Express Scripts, are mostly sold to health insurance plans and employers. Its largest PBM contract is with the Department of Defense, and it recently won a multiyear deal with top-tier insurer Centene. In health insurance and other benefits, Cigna primarily serves employers through self-funding arrangements, and the company operates mostly in the US with 16 million US and 2 million international medical members covered as of December 2025.

Following a 2022 reorganization, Baker Hughes operates in two segments: oilfield services and equipment, and industrial and energy technology. The firm's oilfield services and equipment segment is one of the Big Three oilfield-services players, along with SLB and Halliburton, and mostly supplies to hydrocarbon developers and producers, including national oil companies, major integrated firms, and independents. Markets outside of North America buy roughly three-fourths of the segment's offerings. Baker Hughes' industrial and energy technology segment manufactures and sells turbines, compressors, pumps, valves, and related testing and monitoring services for various energy and industrial applications.
