American Express Reports Strong Q1 Growth Driven by Affluent Demographics

American Express (AXP) has reported a robust start to 2026, with first-quarter revenue climbing 11% year-over-year to exceed management's internal targets. The company's focus on high-net-worth individuals continues to pay off, as luxury spending grew by 18% during the period, significantly outpacing the 10% growth seen in general consumer spending. The results highlight the resilience of the company's affluent customer base amidst broader market volatility. By leveraging a membership-fee model and expanding its rewards ecosystem, Amex is successfully insulating itself from the pressures affecting mass-market credit providers. Financial performance remained strong with earnings per share (EPS) rising 18% to $4.28. The company also observed a significant demographic shift, with millennials and Gen-Z making up 66% of the 3.1 million new cardholders acquired in the first quarter. Notably, 73% of these new members opted for fee-based cards, signaling strong brand loyalty and a willingness to pay for premium services. Despite the stellar figures, the equity market reacted neutrally. Investors focused on management's decision to allocate surplus earnings toward business development and technology—including the new Agentic Commerce Experience developer kit—rather than increasing the full-year outlook. Additionally, some market participants expressed caution regarding rising oil prices and their potential impact on the travel and entertainment sector, though management indicated they are not concerned.
