2021–2025 (latest 5 aligned FYs; v3 window cap 5): revenue $64.9M to $57.9M, decreasing; diluted EPS 0.10 to 0.07, decreasing.

14

Median gross margin 15.9% over 10y, stable.

62

45

84

Owner earnings changed +12.3%/yr over up to the ten most recent annual observations.

Price vs. value if growth stopped today

A cautious baseline, not a price target: what the shares may support if normalized owner earnings simply hold steady.

90% below value if growth stopped today

A discount this large is often a warning rather than a bargain — the market may expect earnings to keep falling. See the revenue trend above.

How to read this

What today’s price assumes: owner earnings shrinking ~37%/yr over 5 years. The estimate assumes owner earnings stay flat (0% growth).

We solve for the constant annual change in owner earnings that would make the five-year zero-growth estimate equal today’s price. This keeps the existing model inputs and calculation unchanged; it is an expectations lens, not a forecast.

This zero-growth estimate assumes trailing owner earnings persist — unreliable for declining businesses. The recent FY revenue series does not trigger the three-consecutive-declines flag.

Among the current top-score group, the median current price is 239% above the zero-growth estimate across 48 of the current top 50 companies by Moat Score with both values.

16 years of fundamentals

The business, in plain English

GREYSTONE LOGISTICS, INC. booked $57.9M of revenue in FY2025 in the Industrials sector and kept 16.4% of it as gross profit — a thin-margin business by that measure. After every other cost, 4.1% of each revenue dollar reached the bottom line.

Across the filed record, revenue grew from $20.5M (FY2011) to $57.9M (FY2025) — about 7.7% a year compounded over 14 years.

It earned 9.5% on invested capital in the latest filed year, FY2025. Across the full 14-year measurable filed record, median ROIC was 15.3%. Over the v3 recent window (10 measurable filed years), median ROIC was 14.5%. The Returns on Capital filter above scores it 62/100.

The balance sheet carried $11.1M of total debt in FY2025 against $2.4M of owner earnings — roughly 4.7 years of owner earnings to retire it all. Balance-Sheet Safety scores it 45/100.

Put together: Capital Allocation is the strongest of the five filters (84/100) and Pricing Power the weakest (14/100), which is how GLGI lands at 46/100 — a Shallow moat.

This breakdown is generated from the filed numbers and sub-scores above — no outside narrative, no estimates. Where a filing doesn’t disclose an input, the sentence that would need it is omitted instead of guessed.

Insider activity

Form 4 reports mix P/S market or private transactions with compensation-plan mechanics. Activity casually described as “insider selling” can include compensation mechanics; awards, tax withholding, and option exercises are shown by their exact filed class here, never collapsed into “Bought” or “Sold.”

These are disclosed filing facts and arithmetic aggregates, not a signal or verdict.

This machine-readable surface covers SEC ownership filings from 2003; it does not represent earlier paper-era records.

Records still being gathered — partial as of retrieval Aug 11, 2026.

9 filings were skipped because the SEC primary document returned 404; the omission is disclosed and aggregates are withheld.

Trailing-12-month totals and the 90-day cluster result are withheld because this issuer walk is incomplete.

No reported Form 4 rows were captured for GLGI; the incomplete walk cannot establish zero activity, zero counts, or a negative cluster result.

Common questions about GLGI

Does GREYSTONE LOGISTICS, INC. have an economic moat?
Based on its FY2025 SEC filings, the Moat Index scores GREYSTONE LOGISTICS, INC. (GLGI) 45.9 out of 100 — a Shallow moat. The five questions behind that score begin at 20% each; if exactly one genuinely lacks data, the other four weights are renormalized and disclosed. revenue and EPS trend 24, pricing power 14, returns on capital 62, balance-sheet safety 45, capital allocation 84.
Is GLGI trading below the conservative owner-earnings estimate?
The value if growth stopped today — a zero-growth baseline — is $2.59 per share. It capitalizes normalized owner earnings at a 9% rate and assumes 0% growth. Versus a recent price of $0.25, that is 90% below value if growth stopped today. The model also publishes a capped-growth comparison, but the zero-growth estimate is the cautious baseline. It assumes trailing owner earnings persist and is unreliable for declining businesses. This is an educational estimate from primary SEC filings, not intrinsic value as a fact or investment advice.
How has GLGI's Moat Score changed over time?
The record logs 15 readings since Jul 17, 2026; the latest reads 45.9 out of 100 (shallow moat). No tier changes on record yet. (Methodology or normalizer upgrades on Jul 20, 2026, Jul 23, 2026, Jul 26, 2026 re-based the score; readings across versions aren't compared.) The history is append-only — readings are only ever added, never rewritten.
