CAR
AERAerCap Holdings N.V.
Rental & Leasing Services · $147.44 · beta 0.93
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.
Rental & Leasing Services · $139.49 · beta 1.90
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.

Where AER and CAR diverge

On the headline score the gap is 19.0 points in favor of AER. The widest single difference is Quality, where AER leads by 21.4 points.

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.
