CAR
The companies
AERAerCap Holdings N.V.
Why now
Rental & Leasing Services · market cap $23.2b. 7% off the 52-week high of $158.81. PEG 0.80 — paying under fair value for the growth rate. 10 sell-side analysts publish a mean 1-yr target of $179.30 (implying +22% 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.
CARAvis Budget Group, Inc.
Why now
Rental & Leasing Services · market cap $4.9b. Down 84% from 52-week high of $847.70 — deep drawdown territory. PEG 0.17 — paying under fair value for the growth rate. 7 sell-side analysts publish a mean 1-yr target of $129.14 (implying -7% upside).
Moat
ROE 20% sits above Buffett's preferred 15% threshold — the equity base is compounding at a rate the market struggles to discount accurately.
Risk
Free cash flow is negative (-$11.4b) — capital raises or debt issuance likely required; dilution / leverage risk. Currently unprofitable (margin -5.7%) — path to GAAP profitability is the core thesis risk. Down 84% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up.

Pillars run 0–100 against sector peers, so a score is a statement about a company relative to its own industry rather than to the other name here. A wide Value gap usually means the market already prices the difference in quality or growth — which is the trade-off this comparison comes down to.
