The companies
AERAerCap Holdings N.V.
Why now
Rental & Leasing Services · market cap $24.3b. Trading near 52-week high of $156.33 — momentum setup, limited technical margin of safety. PEG 0.80 — paying under fair value for the growth rate. 10 sell-side analysts rate this a Strong Buy with a mean 1-yr target of $179.30 (implying +16% upside).
Moat
Net margin 44% is exceptional — pricing-power territory rare outside premium software, branded staples, and specialty pharma. ROE 20% sits above Buffett's preferred 15% threshold — the equity base is compounding at a rate the market struggles to discount accurately. FCF converts 96% of net income — earnings translate cleanly into cash, a sign that working capital and capex are well-disciplined.
Risk
D/E 2.33 is elevated — limits strategic flexibility and raises refinancing exposure if rates stay higher for longer. Trading within 1% of the 52-week high — limited technical margin of safety; a momentum reversal would test conviction.
GATXGATX Corporation
Why now
Rental & Leasing Services · market cap $6.4b. 12% off the 52-week high of $205.56. Revenue growing +23%, comfortably above the S&P median. PEG 0.64 — paying under fair value for the growth rate. 4 sell-side analysts rate this a Strong Buy with a mean 1-yr target of $219.75 (implying +21% upside).
Moat
Net margin 18% beats the market median by a meaningful margin — the company is keeping more of every revenue dollar than the average S&P constituent. ROE 13% meets the long-run market sustainable threshold — solid but not differentiated; the durability comes from elsewhere.
Risk
D/E 3.48 is elevated — limits strategic flexibility and raises refinancing exposure if rates stay higher for longer. Free cash flow is negative (-$858m) — capital raises or debt issuance likely required; dilution / leverage risk.
