iii. Is this a good business?
Moat signal · return on invested capital
119% avg · 5y
FY21 FY22 161%FY23 50%FY24 94%FY25 171%

It earned about 119% 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.

seeing a moat in the numbers →
Management signal · capital allocation
−4% shares · 5y

Share count is down 4% over 5 years — management has been buying back stock, quietly handing owners a bigger slice. Total debt has fallen 48% — 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 $52.31 and $150.62 a share. They rest on different assumptions, so where they diverge is the story; the Graham Number is a stricter floor, not a target.
