Amazon UK Expansion Does Not Alter Affirm's Overvaluation

What happened

Amazon announced on September 23 that it will expand its partnership with Affirm to offer buy-now-pay-later installment options to U.K. customers, extending their existing relationship beyond U.S. markets. This move adds a new geographic channel for Affirm's technology, but the U.K. BNPL landscape is already intensely competitive, with Klarna and other incumbents holding significant share and regulatory scrutiny high. Affirm's shares were volatile around the announcement and have since settled near $73, still trading at roughly 104x trailing earnings and over 200% above our DCF-based intrinsic value of $24 per share. The expansion likely contributes incremental gross merchandise volume, yet it does not address the company's core vulnerabilities: high financial leverage, funding dependence, and thin interest coverage. Consequently, this news does not materially change our assessment that the stock is overvalued relative to its fundamentals.

Implication

Investors should view this expansion as a minor positive that may support longer-term international growth, but it is unlikely to shift near-term profitability or reduce the valuation gap. Affirm's balance sheet remains stretched with net debt-to-EBITDA around 9x and interest coverage below 0.5x, leaving little room for error in a credit downturn or funding squeeze. The U.K. market brings additional regulatory complexity and competition from established players, which could limit margin upside. A meaningful pullback in the stock price, especially toward the $24 DCF value, would restore a margin of safety and could warrant a more constructive view. For now, we advise investors to focus on credit metrics, funding costs, and regulatory developments, and to avoid chasing the stock at current levels.

Thesis delta

The thesis remains a POTENTIAL SELL/avoid due to extreme valuation at ~104x earnings and a leveraged balance sheet. The Amazon UK expansion is a modest positive for growth but does not change the fundamental risk-reward. No change to our stance; we continue to monitor credit, funding, and regulatory factors.
