What American Express Company told the SEC could break it.
American Express's disclosures cluster on its dependence on partners and the contracts that bind them. Its cobrand portfolios — fixed-term partnerships like Delta and Hilton that are intensely competitive to retain — accounted for about 26% of worldwide billed business in 2025 and roughly 36% of Card Member loans, concentrating a large share of both spending volume and credit. It also leans on third-party providers for acquiring and servicing customers, technology platforms, and Membership Rewards redemption. On the other side of its network, it flags litigation over provisions in its merchant contracts, including non-discrimination and honor-all-cards terms, which could force changes to those agreements; broader geopolitical and trade tensions round out the register.
