10 shares is a claim on $80.59 of net worth that earned you $12.76 and generated $7.11 of cash last year, against $178.58 of debt.

iii. Is this a good business?
Moat signal · return on invested capital
9% avg · 5y
FY21 7%FY22 14%FY23 14%FY24 3%FY25 6%

It earned about 9% on invested capital against a ~9% cost of capital — below the cost of funding. The numbers show no moat.

seeing a moat in the numbers →
Management signal · capital allocation
−6% shares · 5y

Share count is down 6% over 5 years — management has been buying back stock, quietly handing owners a bigger slice. Total debt has risen 16% over the same window.

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 $13.22 and $155.38 a share. They rest on different assumptions, so where they diverge is the story; the Graham Number is a stricter floor, not a target.
