Financial summary
American Express
American Express reported $72.2 billion in total revenues net of interest expense for FY2025, up 10 percent, and $10.8 billion of net income, or $15.38 per diluted share. The mix is less fee-only than its premium image suggests: discount revenue on merchant transactions was $37.4 billion, net interest income on card member loans was $17.4 billion, net card fees were $10.0 billion and service fees and other revenue were $7.5 billion. Growth in 2025 came disproportionately from the two smaller lines, with net card fees up 18 percent and net interest income up 12 percent against 6 percent growth in discount revenue. Return on average equity was 33.9 percent, the net write-off rate on consumer and small business loans and receivables was 2.0 percent, and the company declared $3.28 per share in dividends while average diluted shares fell from 713 million to 696 million.
Brex
Brex never published audited results as a private company. Sacra estimates annualized revenue slowed to $312 million in 2022, growing 30%, while the company was reportedly burning about $22 million a month. After the January 2024 restructuring, growth picked up: Brex said in February 2025 that enterprise revenue rose 80% with net revenue retention near 140%, and Sacra estimates total annualized revenue reached $700 million in August 2025, up 50%. Brex turned operating-cash-flow positive for the first time in October 2025, according to Sacra. Before the sale it raised about $2.3 billion in equity. Capital One paid $5.15 billion, roughly 58% below the $12.3 billion valuation of 2021.

Where the revenue comes from
American Express
- Discount Revenue (Merchant Fees)~52%
Discount revenue is the fee American Express charges merchants on card transactions. It was $37,401 million in FY2025, up 6 percent, and equalled 2.24 percent of billed business. It remains the largest revenue line and moves with billed business, merchant mix and geography.
- Net Interest Income~24%
Net interest income is earned on card member loans and receivables after funding costs. It was $17,364 million in FY2025, up 12 percent, on a net interest yield of 8.1 percent, helped by growth in revolving balances and by lending features added to charge card products.
- Net Card Fees~14%
Net card fees are the annual fees on consumer, small business and corporate cards. They reached $9,993 million in FY2025, up 18 percent, at an average of $117 per proprietary card in force, driven by new acquisitions on fee-paying products and by the 2025 Platinum refresh.
- Service Fees and Other Revenue~10%
Service fees and other revenue was $7,471 million in FY2025, up 10 percent. It covers network partnership revenue from cards issued by partner banks, foreign currency fees on cross-currency spending, loyalty coalition and merchant service fees, delinquency fees, travel commissions and income from equity method investments.

Business model and strategy
American Express
How it makes money
American Express runs a closed-loop payments business: it issues the card, owns the network, underwrites the credit and contracts with the merchant. Visa and Mastercard only move the transaction between an issuing bank and an acquiring bank, so they never see both sides of a purchase.
Growth strategy
Amex's growth strategy is aggressively focused on capturing the next generation of wealthy spenders: Millennials and Gen Z. They have successfully revamped their well-known Platinum and Gold cards with perks tailored specifically for younger demographics (like Uber credits and dining rewards), resulting in rapid growth among younger cohorts.
Competitive advantage
American Express competes on the spending power of its card members rather than on price or ubiquity. Average spending per proprietary basic card member was $25,453 in 2025, which is the argument it makes to merchants who pay a higher discount rate, an average of 2.24 percent of billed business.
Brex
How it makes money
Brex makes most of its money from interchange, the fee a merchant's bank pays each time a Brex card is used. Sacra estimates Brex collects about 2.7% of card volume as gross revenue and keeps roughly 65% gross margin after paying its issuing and network partners.
Growth strategy
Brex's growth since 2024 has come from enterprise customers, international companies and partners. It serves more than 300 public companies, holds an EU payment institution licence obtained in August 2025, and distributes its cards through other software: Brex Embedded partners include Navan, Zip, Coupa and Sabre, and Brex is the default commercial card for Fifth Third Bank's commercial clients, according to Sacra.
Competitive advantage
Brex's main technical advantage is its own card-issuing stack. It integrated directly with Mastercard rather than relying on a third-party processor, which lets it issue local corporate cards, settle in local currency and reimburse employees in more than 50 countries. That matters to multinational customers such as Anthropic, Arm and Robinhood.
