Founded in 1850 as a freight express business, the company moved into money orders and traveler's cheques before issuing its first charge card in 1958. Its model differs from Visa and Mastercard: Amex issues cards and acquires merchants itself, a closed loop that lets it earn interest and higher merchant fees while shouldering credit risk. Premium fee-paying cards with travel benefits define the current strategy, aimed at affluent and business spending. The 2015 loss of the Costco portfolio was a notable setback. Headquarters are in New York City.

Equity comp at American Express
- RSUs use single-trigger vesting: shares become yours as each portion vests on schedule, and the value is taxed as ordinary income at that point. No IPO or acquisition is required.

American Express equity questions
- How much AXP stock is too much?
- There is no single threshold, but the larger the share of your net worth in one stock, the more a single bad year can set back your plans. The calculator above quantifies the drawdown impact at 30, 50, and 70 percent for your AXP position and weighs selling down (which triggers capital-gains tax now) against hedging (which costs option premium).
- Does American Express grant ISOs, NSOs, or RSUs?
- Equity compensation at American Express typically takes the form of restricted stock units (RSUs). Restricted stock units are taxed as ordinary income when they vest.
- Do American Express RSUs use double-trigger vesting?
- No. American Express restricted stock units (RSUs) use single-trigger vesting: each tranche becomes yours as it vests on schedule, taxed as ordinary income at that point, with no liquidity event required.
