Another View: Do Multiples Tell a Different Story?

While the fair value model points to potential upside, looking at the company’s price-to-earnings multiple paints a less optimistic picture. Martin Marietta trades at 31.7x earnings, which is much higher than both the US Basic Materials industry average of 15x and peers at 25.8x, and well above its fair ratio of 22.9x. This premium suggests investors are pricing in a lot of growth, which might create valuation risk if expectations slip.
