The thesis, from the filings

INNOVATIVE SOLUTIONS & SUPPORT INC earns about 21% on invested capital, far above its ~9% cost of capital, but has diluted owners by 3% over 5 years — a real edge showing up in the numbers. The estimate methods put fair value between $2.88 and $3.65 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 $36.23 of net worth that earned you $8.77 and generated $3.81 of cash last year, against $27.21 of debt.

It earned about 21% 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.

Share count is up 3% over 5 years — owners have been diluted. Worth asking what they got for it. Total debt has risen 149% 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 $2.88 and $3.65 a share. They rest on different assumptions, so where they diverge is the story; the Graham Number is a stricter floor, not a target.
