The Thesis
Summary
American Express is a premium card network and lender that earns money by charging merchants for processing transactions and cardholders for annual memberships. It generated $80.46 billion in revenue in 2025, an 8.4% increase over the prior year. The company is currently shifting its focus toward a younger, high-spending customer base to ensure its membership model remains relevant for the next generation of travelers.
The core bet on American Express is that it can successfully transition its premium brand to Gen Z and Millennials, who now drive the majority of its new account growth. This strategy secures a pipeline of high-spending users who are willing to pay rising annual fees for travel and dining perks. If this demographic shift continues without a spike in loan defaults, earnings should compound through both membership fees and transaction volume. More specifically, four things need to be true:
We believe American Express is uniquely positioned to win in a digital payments world because it owns the entire relationship with both the cardholder and the merchant. This closed-loop system creates better data and higher profit per transaction than traditional banks can achieve.
Numbers at a Glance
What does it do?
American Express is a mature business that earns money by operating a closed-loop payment network where it acts as both the card issuer and the merchant processor. When a cardholder swipes their card, American Express collects a discount fee from the merchant, which is typically higher than the fees charged by competitors because of the high spending power of its members. The company also charges cardholders annual fees for access to premium travel perks, lounge access, and rewards programs. Unlike most card networks that only process data, American Express also lends money to its cardholders, earning interest on any balances they carry from month to month.
Where does revenue come from?
The majority of revenue comes from discount fees charged to merchants and annual membership fees paid by cardholders. In 2025, total revenue reached $80.46 billion, split across three primary segments: Global Consumer Services, Global Commercial Services, and Global Merchant and Network Services. While transaction fees are the largest driver, the net card fee line is the most durable, as it represents recurring revenue that cardholders pay regardless of how much they spend. The company operates globally but generates the vast majority of its profit from the United States and ten other core international markets.
Revenue Breakdown
Revenue by Geography
Who are its customers?
American Express serves over 140 million cardholders globally and millions of merchants who accept its payment products. The company provides premium credit and charge cards to individual consumers, with a specific focus on high-earning professionals and business travelers. It also serves small and large businesses by providing corporate cards and expense management tools to simplify their accounts payable. In 2024, the company reached 80% merchant coverage across its top 12 international countries, a significant increase from 72% three years prior. This expansion is critical for its "Global Merchant and Network Services" segment, which ensures cardholders can use their cards in more places every year.
What gives it staying power?
The brand creates a powerful network effect: merchants want to accept the card because the members spend more, and members want the card because it is accepted everywhere and offers elite perks. High switching costs also exist because members are reluctant to lose their accumulated reward points or the status associated with premium card tiers.
Where is it headed?
The company is making a major strategic bet on the Gen Z and Millennial demographics to refresh its aging member base. Management is focusing on lifestyle rewards like dining and entertainment to attract younger spenders who are currently responsible for more than 60% of new account acquisitions. If successful, this ensures the company's membership model remains the industry standard for another decade.
The business is delivering consistent growth with revenue reaching a record $80.46 billion in 2025, up 8.4% from the prior year. This growth is driven by a combination of higher merchant fees and record net card fees, proving that members are willing to pay more for premium access.
Free cash flow is exceptionally strong at $16.0 billion, which tracks closely with the company's $10.8 billion in net income. This high cash conversion allows American Express to fund its rewards programs and marketing while returning billions to shareholders through buybacks and dividends.
The balance sheet is managed with a disciplined debt-to-equity ratio of 1.78x, which is conservative for a major financial institution. While the company carries debt to fund its lending activities, its high return on equity of 33.9% shows it is using that capital more efficiently than almost any other bank.
American Express is a financially dominant business that combines the recurring revenue of a subscription model with the scale of a global payments network.
Net card fee revenue reached record levels in 2025 as the company successfully raised prices on several premium card products. Cardholders are showing high loyalty, with retention rates remaining steady even as annual fees for the Gold and Platinum cards have increased.
Provisions for credit losses must be monitored closely as the company expands its lending to younger customers who have shorter credit histories. If the economy slows, these newer cohorts could see higher delinquency rates than the established premium members who have traditionally anchored the business.
The global credit services and payments market is a multi-trillion dollar industry growing at roughly 8% annually as the world moves away from cash. Pricing power in this industry is structural for players who control their own networks because they can set the rates that merchants and banks must pay. American Express stands as a dominant leader in the premium niche, where it uses its unique "closed-loop" model to capture higher margins than the open networks that only process data.
The payment industry is rationally structured but brutally competitive at the top, with a few massive players dominating the landscape. Barriers to entry are immense because a new competitor would need to convince millions of merchants to accept their card and millions of people to carry it simultaneously. High barriers to entry protect the margins of the established players who already have global scale.
Visa(V) and Mastercard(MA) are the most dangerous threats because their universal acceptance makes them the "default" card for most people. JPMorgan(JPM) and Capital One(COF) are attacking American Express specifically by launching premium travel cards that offer similar lounge access and luxury perks to steal high-end customers. The most direct threat comes from the Chase Sapphire Reserve, which has successfully mimicked the American Express lifestyle brand for younger professionals.
American Express is successfully holding its ground, evidenced by the fact that Gen Z and Millennials now make up its fastest-growing customer segment. The company is gaining share in the high-end travel and dining category.
The primary source of protection is the closed-loop network effect combined with a powerful luxury brand. Unlike competitors who rely on external banks, American Express manages the relationship with both the buyer and the seller, giving it a data advantage that allows for better fraud detection and higher merchant fees. The brand acts as a status symbol that allows the company to charge hundreds of dollars for a card that competitors often give away for free.
The company’s 33.9% return on equity and 83.5% gross margins prove that its advantage is structural and not just the result of a good business cycle. These numbers are consistently higher than those of traditional banks, confirming that the membership model creates superior unit economics. The high net card fees provide a floor for earnings that protects the business during periods of lower consumer spending.
The moat is strengthening as the merchant network expands toward parity with Visa, removing the last major reason for a customer to switch cards. The brand’s successful transition to younger demographics is the clearest signal that its competitive advantage is durable.
