Revenue Growth
A company’s long-term sales performance can indicate its overall quality. Even a bad business can shine for one or two quarters, but a top-tier one grows for years. Regrettably, Martin Marietta Materials’s sales grew at a mediocre 6.6% compounded annual growth rate over the last five years. This was below our standard for the industrials sector and is a poor baseline for our analysis.
