The five investor questions

29

2022–2026 (latest 5 aligned FYs; v3 window cap 5): revenue $50.8M to $50M, decreasing; diluted EPS 0.34 to -0.23, decreasing.

55

Median gross margin 39.1% over 10y, stable.

14

Median ROIC -7.7%, above the 12% hurdle in 40% of years.

55

Net cash position — no leverage risk.

24

Owner earnings changed trend unclear 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.

Above value if growth stopped todayBelow value if growth stopped today
2041% above value if growth stopped today
$9.4M
$3.23
$3.23
$69.21
2041% above value if growth stopped today

What today’s price assumes: owner earnings growing ~85%/yr over 5 years. The zero-growth estimate assumes owner earnings stay flat (0% growth).

How to read this

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 255% above the zero-growth estimate across 49 of the current top 50 companies by Moat Score with both values.

Score records captured Oct 16, 2026.

Model details under moat-index@3.0.0: zero-growth multiple 11.1×, capped-growth comparison at no more than 18×; 9% discount rate; high-end growth 0% (capped at 4%) using min(5y revenue CAGR, 5y diluted-EPS CAGR), clamped to 0%–4%; maintenance capex uses min(capex, D&A); abstain when D&A is unavailable. This is a disclosed model range, not intrinsic value as fact.

18 years of fundamentals

The business, in plain English

AEHR TEST SYSTEMS booked $50M of revenue in FY2026 in the Healthcare sector and kept 35.3% of it as gross profit — a solid-margin business by that measure. After every other cost, −14.3% of each revenue dollar reached the bottom line.

Across the filed record, revenue grew from $11.7M (FY2010) to $50M (FY2026) — about 9.5% a year compounded over 16 years.

It earned −10.8% on invested capital in the latest filed year, FY2026. Across the full 17-year measurable filed record, median ROIC was −21.2%. Over the v3 recent window (10 measurable filed years), median ROIC was −7.7%. The Returns on Capital filter above scores it 14/100.

AEHR'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: Pricing Power is the strongest of the five filters (55/100) and Returns on Capital the weakest (14/100), which is how AEHR lands at 35/100 — a None 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.

The explained ROIC gaps have filed inputs but no meaningful positive invested-capital denominator. Other gaps mean the item is not in the filings for that year. The series is never interpolated or estimated. The Table view lists every filed value, including operating and net margins, total debt, and share count.

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 Oct 16, 2026.

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

Among the rows shown, A/F/M acquisition, payment or withholding, and exercise or conversion rows outnumber S sale rows (27 versus 18). The filing codes alone do not establish that every such row arose from a compensation plan.

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

Track record

How AEHR TEST SYSTEMS’s moat rated in each of the years we can reconstruct from its filings — scored only on what was knowable at the time — and what its price and returns did afterward. The score never saw a price; the two are joined only in hindsight, for education, not as a signal.

Point-in-time scores 2011–2025, one methodology version · reconstructed from filings on file each Dec 31 — never with hindsight

Point-in-time Moat Score (dot colored by tier)Indexed price (total-return (dividends reinvested))Rated Wide-moat that year

How to read this: each dot is what the engine would have scored AEHR on that December 31; the line below is its total-return price path (dividends reinvested) in the years since.

0406080100WideNarrowShallowNo moatPoint-in-time Moat Score1002005001,0002,0005,000Indexed price · log scale (2012 = 100)201120142017202020232026

Two tracks, one timeline: the score has its own 0–100 scale (top), the price its own 100-based scale (bottom) — never a shared axis. The price path is a total-return (dividends reinvested) index built from the same data the forward returns use; gaps in the score line are years with no reconstructed rating (see the table for why). The Table view carries every value.

What followed, in the years it rated Wide

In the reconstructed history shown, AEHR did not rate Wide-moat in any year, so there is no wide-moat track record to report. That absence is itself the honest answer — we don’t manufacture a comparison where the rating never earned one.

Common questions about AEHR

Does AEHR TEST SYSTEMS have an economic moat?
Based on its FY2026 SEC filings, the Moat Index scores AEHR TEST SYSTEMS (AEHR) 35.4 out of 100 — below the Shallow-moat bar, so no 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 29, pricing power 55, returns on capital 14, balance-sheet safety 55, capital allocation 24.
Is AEHR trading below the conservative owner-earnings estimate?
The value if growth stopped today — a zero-growth baseline — is $3.23 per share. It capitalizes normalized owner earnings at a 9% rate and assumes 0% growth. Versus a recent price of $69.21, that is 2041% above 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 AEHR's Moat Score changed over time?
The record logs 29 readings since Jul 17, 2026; the latest reads 35.4 out of 100 (no moat). Tier changes so far: Shallow moat → No moat on Sep 4, 2026. (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.
