American Express Company AXP
LONG price $308.10 · base case $398.22 · expected +18% over 540 days
The call
American Express generates $21,372M of trailing FCFF at a 49.6% margin from an integrated premium card-issuing, merchant-acquiring, and network platform with recurring fee and interest income. The base-case DCF values the stock at $398.22 vs. the $308.10 price, a 29.2% gap, driven by mid-single-digit FCFF growth consistent with the company's own 6.4% revenue CAGR, 8.9% YTD growth, and management's 10% FY2026 guidance. The earnings multiple corroborates the direction at $341.47 (10.8% upside) on 18.5x forecast EPS of $18.46. The probability-weighted value of $363.97 (18.1% upside) reflects a 50% base, 25% bear, 25% bull weighting.
Why the opportunity exists, in the desk's view: a narrative overshoot.
What decides the case
