GARMIN LTD vs Rocket Lab Corp, two Aerospace & Defense stocks. A side-by-side on valuation, growth, margins, returns, and what each price is betting.
Garmin makes money the easy-to-love way: a 23.26% net margin on GPS devices and aviation electronics, 18.73% return on equity, zero debt, and a $45.0B cap at 25.96 times earnings. Rocket Lab, at a similar $51.2B cap, makes no money at all yet. It builds small rockets and space systems, runs a -26.87% net margin, and burns a little cash while it scales, holding almost no debt at 0.02. The two caps sit close together, but they describe opposite things. Garmin is priced on profits it already banks. Rocket Lab is priced on a space business the market is betting will exist at scale one day.
