What the numbers say

Idexx Laboratories is scored 97 for moat and 97 for management. The management score rests on a return on invested capital of 40.3% and a gross margin of 61.8% — figures that describe a business turning capital into profit efficiently. Debt sits at 0.67x equity.

The price anchors are built on deliberately conservative assumptions. Growth is modelled at 9.7% a year, below the 10.0% actually measured over the last decade — the model caps growth rather than extrapolating a good run forwards. The exit multiple assumed is 19.4x. That produces an intrinsic value of $171.52, a 10-CAP price of $159.37 and a payback time price of $197.94, with the value zone set at the highest of the three, $197.94. Today's price of $517.75 is 162% above it.

A wonderful business at the wrong price is still the wrong price. Idexx Laboratories scores well on the business and poorly on the entry point, which is the most common shape in a long bull market.
