What the numbers say

On the four Ms, West Pharmaceutical Services earns 100 for management and 73 for moat. The management score rests on a return on invested capital of 13.6% and a gross margin of 35.9% — figures that describe a business turning capital into profit efficiently. Debt sits at 0.13x equity. The solid 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 7.4% a year, the rate measured from the filings. The exit multiple assumed is 14.9x. That produces an intrinsic value of $58.99, a 10-CAP price of $70.76 and a payback time price of $79.25, with the value zone set at the highest of the three, $79.25. Today's price of $365.01 is 361% 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 8 is the measure of how little room that leaves for being wrong.
