What the numbers say

Builders FirstSource scores 84 for management and 57 for moat. The management score rests on a return on invested capital of 6.8% and a gross margin of 29.0% — figures that describe a business turning capital into profit efficiently. Debt sits at 1.30x equity. The moderate moat and exceptional management are not the same judgement, and the gap between them is where the argument about this business sits.

Three independent anchors set the price worth paying. Growth is modelled at 12.2% a year, the rate measured from the filings. The exit multiple assumed is 24.3x. That produces an intrinsic value of $17.23, a 10-CAP price of $65.95 and a payback time price of $91.50, with the value zone set at the highest of the three, $91.50. Today's price of $57.35 sits inside that zone.

A business scoring this well, trading inside its value zone, is the combination the framework exists to find — which is also the reason to check why the market disagrees. A margin of safety score of 15 describes the cushion, not the certainty.
