American Express ownership and investment activity

In late July 2026, American Express completed the acquisition of the remaining stake in Swisscard, making the Swiss credit‑card operation a wholly‑owned subsidiary after UBS transferred its Credit Suisse‑inherited share. The move solidified Amex’s presence in the Swiss market, where premium cards retain high annual fees.

A few days later, in early August 2026, filings showed a wave of institutional investors expanding their holdings in American Express. Segall Bryant & Hamill, Rathbones Group, and several pension funds and asset managers increased their share positions, pushing institutional ownership to roughly 84 % of the company’s stock. The filings reflected broader portfolio rebalancing and positive analyst sentiment toward the payment‑services firm.

Together, the snapshots illustrate a period in which American Express both consolidated its international operations and attracted heightened interest from large investors.
