The thesis, from the filings

FASTENAL CO earns about 30% on invested capital, far above its ~9% cost of capital, but has diluted owners by 99% over 5 years — a real edge showing up in the numbers. The estimate methods put fair value between $10.37 and $27.84 a share.Whether it’s worth owning at today’s price is the last question — and yours to answer, below.

10 shares is a claim on $34.28 of net worth that earned you $10.94 and generated $9.13 of cash last year, against $2.17 of debt.

iii. Is this a good business?

FY21 26%FY22 27%FY23 32%FY24 31%FY25 32%

It earned about 30% 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
+99% shares · 5y

Share count is up 99% over 5 years — owners have been diluted. Worth asking what they got for it. Total debt has fallen 68% — deleveraging.

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 $10.37 and $27.84 a share. They rest on different assumptions, so where they diverge is the story; the Graham Number is a stricter floor, not a target.
