CM vs CI Comparison

Canadian Imperial Bank of Commerce is Canada's fifth-largest bank with over CAD 1.1 trillion in assets at the end of fiscal 2025. It operates four business segments: Canadian retail and business banking, Canadian commercial banking and wealth management, US commercial banking and wealth management, and capital markets. It serves approximately 14 million personal banking and business customers, primarily in Canada and the US.

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 (current contract through 2029), 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 17 million US and 2 million international medical members covered as of December 2024.
