It earned about 19% on equity, year after year, against a ~9% cost of capital — the footprint of real pricing power. Competition usually drags returns like this back down; here it hasn't.

Share count is roughly flat over 5 years — little dilution, little buyback. Total debt has fallen 32% — deleveraging.

iv. What it’s worth — engine v0.1.0

The 3 estimate methods that apply put fair value between $53.43 and $103.53 a share. They rest on different assumptions, so where they diverge is the story; the Graham Number is a stricter floor, not a target.
