American Express’s affluent cardmembers are showing few signs of curbing their spending, and younger customers drove growth in first-quarter transaction volumes, Chief Financial Officer Christophe Le Caillec told CNBC.

Cardmember spending, credit performance, and demand for the company’s premium products were strong in the first quarter, says Chief Executive Stephen Squeri.

American Express CEO Stephen Squeri said the firm saw first-quarter consumer spending "consistent with and in many cases better than what we saw in 2024." The company affirmed its full-year outlook of 8% to 10% revenue growth and EPS of $15.00 to $15.50 "subject to the macroeconomic environment."
