American Express Company announced on May 4, 2026 (filed via Form 8-K, Item 8.01) that it issued $1,750,000,000 aggregate principal amount of 4.444% Fixed-to-Floating Rate Notes due May 3, 2030.

Key Details

• Amount issued: $1,750,000,000 aggregate principal.
• Coupon/type: 4.444% Fixed-to-Floating Rate Notes (initial fixed rate noted in filing).
• Maturity: May 3, 2030; issuance date: May 4, 2026.
• Legal/registration: Issued under the company’s senior indenture (original and supplemental indentures) and offered pursuant to a prospectus supplement filed April 27, 2026.

Why It Matters
This issuance increases American Express’s outstanding debt by $1.75 billion and secures medium‑term funding through 2030. For investors, the fixed 4.444% coupon locks in borrowing cost for the initial period and the fixed-to-floating structure means future interest expense may change when the rate converts. The filing is a routine financing disclosure rather than a change to operations or management, but it is material to capital structure, leverage metrics, and interest expense forecasts.
