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.
Amphenol
Amphenol compounds through acquisition in a fragmented industry. Net sales rose from $12.55 billion in 2023 to $15.22 billion in 2024 and $23.09 billion in 2025, and net income rose from $1.93 billion to $2.42 billion and then $4.27 billion across the same three years. Fiscal 2025 produced a 25.4% GAAP operating margin, $5.4 billion of operating cash flow and $4.4 billion of free cash flow, and the company returned nearly $1.5 billion to shareholders while completing five acquisitions. The pattern is consistent: buy niche connector, cable and sensor makers, leave their management and brands in place, add purchasing scale, and fund the next deal from cash flow and investment grade debt.

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.

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.
Amphenol
How it makes money
The business model is high volume, highly specialized B2B component manufacturing. Amphenol sells hundreds of thousands of connector, cable, antenna and sensor variants to thousands of customers, and no single end market dominates: in 2025, data centers and information technology accounted for 36% of sales, industrial 19%, automotive 15%, communications networks 10%, defense 9%, mobile devices 6% and commercial aeros…
Growth strategy
Amphenol's growth strategy has two parts: sell into secular demand and buy specialized suppliers. On the first, it builds high speed copper and optical interconnects for AI clusters, including the Celerity mezzanine connector family rated to 224 Gb/s PAM4 and XtremePass co-packaged copper interconnects aimed at 448G class links, plus high voltage connectors and sensors for electric vehicles, which carry more wiring a…
Competitive advantage
Amphenol's competitive advantage rests on switching costs and the cost of failure. A connector may cost a few cents, but if it fails the aircraft, satellite or server rack around it stops working, so buyers qualify suppliers rather than shop on price.
