The thesis, from the filings

GREYSTONE LOGISTICS, INC. earns about 10% on invested capital, barely covering its ~9% cost of capital, and has bought back 12% of its shares over 5 years. The estimate methods put fair value between $1.65 and $8.69 a share.Whether it’s worth owning at today’s price is the last question — and yours to answer, below.

i. The business — what you’d actually own

10 shares is a claim on $6.96 of net worth that earned you $0.82 and generated $1.59 of cash last year, against $7.76 of debt.

iii. Is this a good business?
Moat signal · return on invested capital
10% avg · 5y
FY21 10%FY22 12%FY23 12%FY24 10%FY25 6%

It earned about 10% on invested capital against a ~9% cost of capital — roughly what it costs to fund the business, so the numbers show no clear edge.

seeing a moat in the numbers →
Management signal · capital allocation
−12% shares · 5y

Share count is down 12% over 5 years — management has been buying back stock, quietly handing owners a bigger slice. Total debt has fallen 32% — 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 $1.65 and $8.69 a share. They rest on different assumptions, so where they diverge is the story; the Graham Number is a stricter floor, not a target.
