L3HARRIS TECHNOLOGIES, INC. vs Rocket Lab Corp, two Aerospace & Defense stocks. A side-by-side on valuation, growth, margins, returns, and what each price is betting.
L3Harris is a profitable defense-electronics supplier, if a modest one: 8.8% on equity, a 4.48% net margin, a 1.65% dividend, priced at 31.62 times earnings and 2.78 times book, a $54.8B cap. Rocket Lab, at $51.2B, sits close in size but nowhere near in maturity, building small rockets and space systems at a -26.87% net margin, burning a sliver of cash, carrying next to no debt at 0.02. L3Harris earns real profit from established defense contracts. Rocket Lab spends to chase a space market it believes will pay off later. Similar market values, wholly different stages of life.
