American Express Company AXP
LONG price $302.78 · base case $437.94 · expected +41% over 365 days
The call
American Express operates a high-quality, integrated premium payments network with a resilient, creditworthy customer base and a proven capital return profile. Management raised 2026 revenue growth guidance to 10% and maintains EPS guidance of $17.30-$17.90, supported by disciplined expense management and strong billed business growth (USCS up 11% YoY). The DCF base case values the stock at $437.94 (44.6% upside), driven by sustainable mid-single-digit FCFF growth from a 49.6% FCFF margin and consistent buybacks ($7.5B TTM). The company's differentiated Membership Model, expanding commercial footprint, and premium product cycles support a structural valuation premium.
Why the opportunity exists, in the desk's view: a narrative overshoot.
