American Express earned $4.53 a share in the second quarter, up 11% from a year ago and ahead of the roughly $4.45 consensus. Card members put $455.8 billion through the network, up 9% — the strongest card-member spending growth in three years on a currency-adjusted basis. Management raised its full-year revenue growth guidance to about 10%. And the stock dropped roughly 6% by mid-morning, from Thursday’s $340.84 close into the low $320s, one of the sharpest falls in the S&P 500 on a day the index barely moved.
The complaints, such as they are: revenue of about $19.6 billion was a record but landed a touch under Street models, with net interest income the soft spot. And while the revenue outlook went up, the full-year earnings guide didn’t move — it stayed at $17.30–$17.90 a share, with management saying the top-line outperformance is being funneled back into growth investment rather than dropped to the bottom line. Wall Street heard “we’re making more money and you’re not getting it yet,” and traded it accordingly.
If the fade feels familiar, it should. Four of AmEx’s last five earnings beats produced negative same-day reactions. Meanwhile Visa and Mastercard barely budged this morning — this was a company-specific tantrum about expectations mechanics, not a verdict on payments.
The affluent consumer just raised their hand
Strip out the stock reaction and this print is one of the cleanest macro data points of the season. AmEx’s card base skews premium — and that cohort is accelerating, posting its best spending growth since 2023. Set that against Equifax’s warning this week that inflation is squeezing lower-income borrowers, and the picture sharpens into a cleanly split, K-shaped consumer: the top of the income distribution is spending faster while the bottom frays. It rhymes with record retail brokerage activity at Interactive Brokers — the affluent household is engaged, liquid, and transacting — and with AMC’s record quarter, which showed consumers still show up when they want the product. The money is there. It’s just concentrated.
Our take: The 6% is noise; the guidance structure is the signal. A company raises its revenue outlook and holds EPS flat for one of two reasons: trouble it isn’t admitting, or opportunity it’s choosing to fund. With spending accelerating and the beat coming in clean, this reads like the second — AmEx is spending into strength while its target customer is pulling away from the pack. If you run a business, the read-through is blunt: pricing power lives at the premium end of the market right now, and the companies serving that end are reinvesting, not harvesting. If your customers look more like Equifax’s warning than AmEx’s cardholders, build your back-half plan for a tighter wallet.
What to watch
- Visa and Mastercard’s network volumes: They see the whole income distribution, not just the premium slice. If their growth decelerates while AmEx accelerates, the K-shape hardens from thesis into fact.
- Where the reinvestment shows up: Held EPS guidance means marketing and card-acquisition spend rises into year-end. Watch whether account growth follows — that’s the payoff the Street is being asked to wait for.
- The fade-then-recover pattern: AmEx has been sold on four of its last five beats. How fast dip-buyers absorb this one is a live read on whether quality large-caps still get bought on weakness in this tape.
