American Express CompanyArticle highlights American Express's strong moat, premium brand, and closed-loop network, with expected 10% revenue growth and 14% EPS growth in 2026.
American Express, Berkshire Hathaway's second-largest holding valued at more than $50 billion, possesses a durable competitive advantage built on a premium brand and a closed-loop network effect, yet the duopoly of Visa and Mastercard arguably holds the widest economic moat in payments. American Express targets affluent customers, resulting in a net write-off rate of 2% in the second quarter, half the industry average of 4%, while average spend per card rose 34% and average fee per card jumped 77% over the past five years. The company's closed-loop system strengthens its network effect as more cardholders and merchants join. However, Visa and Mastercard's ubiquitous reach, with billions of active cards and trillions of dollars in quarterly volume, along with average quarterly operating margins of 67% and 58% respectively over the past five years, underpin their dominant position. American Express still expects 10% revenue growth and over 14% earnings per share growth in 2026.
