About the company

American Express issues credit and pay-in-full charge cards to consumers and businesses, and unlike most card issuers it also runs the payment network its cards use. Its Travelers Cheque, launched in 1891, made carrying money abroad safer, and in 1959 it became the first major issuer of plastic cards. Cardholders earn points toward flights and hotels plus perks such as airport lounges, while companies use its corporate cards for employee travel and expenses. American Express earns a fee from merchants on each purchase, plus annual fees and interest on balances cardholders carry. Henry Wells and William Fargo, who later started Wells Fargo, co-founded it in 1850 as a freight delivery business; it is based in New York City.

Eli Lilly, Tractor Supply and American Express have doubled dividends in five years

Eli Lilly, Tractor Supply Company, and American Express have each more than doubled their quarterly dividends in five years, and their payout ratios suggest more increases could follow. Eli Lilly now pays $1.73 a share, up from $0.85 in 2021. Its payout ratio is 22%, though its yield is only 0.6%. Tractor Supply pays $0.24 a quarter. After a 5-for-1 split in 2024, that is a 131% rise from the split-adjusted $0.104 in 2021. Its yield is 2.9% and its payout ratio about 50%, but the stock is down 33% in 2026. American Express pays $0.95, up 121% from $0.43. Its payout ratio is about 20%, and its shares are down 16% this year.

United Airlines sees loyalty revenue surge 13% as Amex cardholders boost premium spending

United Airlines reported strong second-quarter results driven by loyalty programmes, with American Express playing an unexpected role despite not co-branding a card with the carrier. United's MileagePlus card is issued exclusively by Chase through 2029, but Amex channels premium spend through its Platinum cardholders, who can designate United for a $200 annual credit on bags and fees. Business Platinum holders receive a 35% rebate on economy fares booked through Amex Travel. The airline also benefits from Amex's transfer partnerships with programmes like Air Canada Aeroplan and Singapore KrisFlyer, which provide access to United seats. United's chief commercial officer reported new co-branded card accounts rose 22% year-over-year, hitting a second-quarter record, whilst card spend increased 14%. Loyalty revenue grew 11.3%, or above 13% when adjusted for accounting changes.
