The five investor questions

2022–2026 (latest 5 aligned FYs; v3 window cap 5): revenue $1.1M to $6.5M, increasing; diluted EPS -2.07 to 4.83, increasing.

Median gross margin -24.3% over 7y, variable.

Net cash position — no leverage risk.

Owner earnings changed trend unclear over up to the ten most recent annual observations.

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.

15 years of fundamentals

The business, in plain English

Across the filed record, revenue grew from $2.8M (FY2013) to $6.5M (FY2026) — about 6.8% a year compounded over 13 years.

It earned 54.3% on invested capital in the latest filed year, FY2026. Across the full 12-year measurable filed record, median ROIC was −19.3%. Over the v3 recent window (10 measurable filed years), median ROIC was −23.8%. The Returns on Capital filter above scores it 4/100.

ATEX's latest filed year, FY2026, doesn't disclose total debt in a form the methodology can use, so current leverage is treated as unmeasured — never assumed to be zero.

Put together: Balance-Sheet Safety is the strongest of the five filters (100/100) and Pricing Power the weakest (0/100), which is how ATEX lands at 42/100 — 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.

The insider-filing service is temporarily unavailable, so no partial or guessed answer is shown for ATEX.
