American Express
Thesis
- The business: a closed-loop premium membership business - issuer, network and merchant acquirer at once, getting paid on both sides of the same transaction.
- Moat:
- Two-sided scale. Closed loop owning members and merchants.
- U.S. anti-steering protection (2018).
- Premium brand.
- Commercial card scale.
- Economics:
- Network-like merchant fees and issuer economics on a spend-centric low-loss customer base.
- The merchant fee mostly funds the card member proposition. Card fees and interest are the source of profit.
- Growth drivers:
- Structural: Premium card fees (high retention rates after fee increases). Spend from younger and international cast members. Merchant take rate a headwind.
- Cyclical: Lending and net interest income, commercial spend.
- Business direction: focus on proprietary fee-paying relationships owned by Amex.
- Risks:
- Delta concentration.
- Benefit inflation outrunning fees.
- Three-party exemption eroding.
- Merchant steering.
- Downside mechanism: a recession, cutting spend and forcing a reserve build, just as merchants gain tools to decline premium costs.
