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. ## Timeline ### 2026-08-03: Institutional investors boost American Express holdings in Q1 Institutional investors, including Segall Bryant & Hamill and Rathbones Group, increased their American Express stakes in Q1, adding millions of dollars in shares. 2 sources. https://clstr.news/cluster/institutional-investors-boost-american-express-holdings-in-q1 ### 2026-07-31: American Express gains full control of Swisscard as credit‑card revenue growth fuels earnings American Express’s mixed‑revenue model drives earnings, and the firm now fully owns Swisscard, taking control of its Swiss credit‑card business after a UBS‑Credit Suisse stake transfer. 2 sources. https://clstr.news/cluster/american-express-gains-full-control-of-swisscard-as-creditcard-revenue-growth-fuels-earnings --- Cite as: American Express ownership and investment activity.
