American Express disclosed strong execution on its September 2025 Platinum card refresh during its Q4 2025 earnings call, with retention unchanged at the new $695 price point despite a $100 annual fee increase. The filing reveals customer engagement metrics exceeding management expectations: travel bookings increased 30% in Q4 and restaurant spending rose 20% among refreshed cardholders, while customer acquisition costs reached multi-year lows.

The company reported card fee revenue of $10 billion for full-year 2025, up 18% year-over-year. Management guided to "high teens" growth in 2026 as more Platinum renewals convert to the $695 price point, representing a mechanical acceleration from the current 16% quarterly run rate.

Credit quality showed unusual divergence from industry trends. The CFO stated delinquencies remained flat year-over-year and write-offs stayed below 2019 levels, explicitly contrasting this with "many competitors seeing small increases." Management attributed the improvement to premium mix shift, with fee-paying products rising 8 percentage points as a percentage of new customer acquisitions.

The call disclosed that American Express's Gen-3 analytics platform, migrated to public cloud infrastructure, reduced marketing and fraud process time by 90%. Management stated the platform is already contributing to lower customer acquisition costs on premium products, with full migration expected by 2027.

Operating leverage accelerated: operating expenses as a percentage of revenue declined 4 percentage points since 2022 despite technology spending increasing 20% over the past two years. For 2026, management guided operating expenses to grow mid-single digits against revenue growth of 9-10%.

Net interest income grew 12% in Q4 versus 7% receivables growth. Management stated they "expect NII to continue to outpace growth of loans and receivables in 2026," indicating revenue yield expansion beyond volume growth.

The company reported millennial and Gen Z customers now represent the largest spending cohort, with average ages of 29 for Gold cardholders and 33 for Platinum cardholders. Management characterized this as a "long runway to grow relationships over time."

Full-year 2025 results: revenue of $72 billion (up 10%), EPS of $15.38 (up 15%), return on equity of 34%, with $7.6 billion returned to shareholders. The company raised its quarterly dividend 16% to $0.95.
