The thesis, from the filings

The estimate methods put fair value between $26.53 and $42.44 a share.Whether it’s worth owning at today’s price is the last question — and yours to answer, below.

iii. Is this a good business?

It earned about 26% on invested capital, 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.

Management signal · capital allocation
−7% shares · 5y

Share count is down 7% over 5 years — management has been buying back stock, quietly handing owners a bigger slice.

Signals, not verdicts — read from the filings above. Numbers don’t prove a moat; they show its footprint. You decide.

iv. What it’s worth — engine v0.1.0

The 3 estimate methods that apply put fair value between $26.53 and $42.44 a share. They rest on different assumptions, so where they diverge is the story; the Graham Number is a stricter floor, not a target.
