American Express (NYSE: AXP) lifted its full-year revenue growth outlook to 10%. The move follows a second quarter that beat expectations and posted the strongest foreign-exchange adjusted card member spending growth in three years. Management is sending a clear message: it will reinvest the outperformance, not simply pocket it.
Revenue rose 10% year-over-year to $19.6 billion, just shy of the $19.7 billion consensus but powered by a clean mix. Card member spending climbed 9% on an FX-adjusted basis, the highest rate in three years. Net interest income increased 11% to $4.6 billion, helped by 8% growth in average card balances. Card fees jumped 15% to $2.9 billion, a sign of the ongoing shift toward premium products. Diluted EPS of $4.53 beat the $4.40 estimate by 2.9% and grew 11% from $4.08 a year ago.
The earnings beat arrived despite a 12% rise in total operating expenses to $14.5 billion. Variable customer engagement costs increased 17%. Higher spending, the U.S. Platinum Card refresh, and greater benefit usage all drove costs higher. That is the model working: more engagement, more rewards, more services. The offset came from provisions. Total provisions for credit losses fell 23% to $1.1 billion, reflecting a reserve release this quarter versus a build a year ago. The net write-off rate (principal only) stayed flat at 2.0%, and the reserve as a percentage of card balances improved to 2.7% from 3.0%. Credit quality is not just stable; it is improving relative to the portfolio's size.
The guidance change is the quarter's most consequential signal. Full-year revenue growth was raised to 10% from a previously unspecified level. Full-year EPS guidance of $17.30 to $17.90 was reiterated. The combination is unusual. A company raising revenue guidance typically has room to raise EPS guidance too, unless it is choosing to spend the incremental revenue. That is precisely what management said it would do: reinvest the outperformance into growth initiatives. The implied message is that the return on those investments exceeds the return of capital to shareholders in the near term, and the opportunity set is large enough to justify the trade-off.
Segment performance supports the confidence. U.S. Consumer Services revenue grew 11% to $9.5 billion, with billed business up 11%. CEO Stephen Squeri noted the Platinum portfolio is now the fastest-growing part of the U.S. Consumer business. International Card Services revenue rose 12% to $3.6 billion, with billed business up 13% (12% FX-adjusted). Commercial Services grew revenue 7% to $4.5 billion, a more modest pace reflecting the segment's lower spending growth and a 5% decline in proprietary cards-in-force after a small business cobrand portfolio sale.
The proposed acquisition of TheFork, a European restaurant booking platform with 50,000 restaurants across 11 countries, fits the premium ecosystem strategy. It adds a dining reservation asset to a portfolio that already includes travel benefits, concierge services, and partnerships with Delta, Accor, and Fanatics. The deal is small relative to the balance sheet, but it signals where management sees the next layer of engagement value.
The forward question is whether the reinvestment thesis holds if the macro environment softens. Consumer spending has been resilient, yet the 10% revenue guide assumes that momentum continues. The reiterated EPS range of $17.30 to $17.90 implies second-half earnings roughly in line with the first half, meaning the revenue raise is not flowing through to the bottom line. That is a deliberate choice. The test will come in the next two quarters, when spending on growth initiatives meets whatever the consumer environment delivers.
