Martin Marietta Materials scores 69 for management and 82 for moat. The management score rests on a return on invested capital of 6.9% and a gross margin of 30.0% — figures that describe a business earning a respectable return on what it employs. Debt sits at 0.53x equity. The wide moat and strong management are not the same judgement, and the gap between them is where the argument about this business sits.
The valuation runs on assumptions chosen to understate rather than flatter. Growth is modelled at 6.7% a year, below the 7.0% actually measured over the last decade — the model caps growth rather than extrapolating a good run forwards. The exit multiple assumed is 13.4x. That produces an intrinsic value of $258.37, a 10-CAP price of $169.88 and a payback time price of $184.05, with the value zone set at the highest of the three, $184.05. Today's price of $479.17 is 160% above it.
The operating figures describe a business performing at a high level; the price asks for that performance to continue and then some. A margin of safety score of 27 is the measure of how little room that leaves for being wrong.
