The five investor questions

70

2022–2026 (latest 5 aligned FYs; v3 window cap 5): revenue $2.8B to $3.1B, increasing; diluted EPS 3.15 to 5.44, increasing. Latest-filed diluted EPS remains usable for Business Trend, but an integer share-count change lacks enough evidence to confirm a comparable EPS basis; valuation growth therefore stays at 0%.

31

Median gross margin 31.9% over 10y, variable.

75

Median ROIC 15.9%, above the 12% hurdle in 80% of years.

77

Net debt/EBITDA 1.7x, no material interest expense disclosed.

60

Owner earnings changed +19.2%/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.

Above value if growth stopped todayBelow value if growth stopped today
106% above value if growth stopped today
$450M
$68.85

106% above value if growth stopped today

What today’s price assumes: owner earnings growing ~16%/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 239% above the zero-growth estimate across 48 of the current top 50 companies by Moat Score with both values.

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.

15 years of fundamentals

The business, in plain English

ADVANCED DRAINAGE SYSTEMS, INC. booked $3.1B of revenue in FY2026 in the Materials sector and kept 38.3% of it as gross profit — a solid-margin business by that measure. After every other cost, 14.0% of each revenue dollar reached the bottom line.

Across the filed record, revenue grew from $1.0B (FY2013) to $3.1B (FY2026) — about 8.8% a year compounded over 13 years.

It earned 14.5% on invested capital in the latest filed year, FY2026. Across the full 13-year measurable filed record, median ROIC was 15.5%. Over the v3 recent window (10 measurable filed years), median ROIC was 15.9%. The Returns on Capital filter above scores it 75/100.

The balance sheet carried $1.6B of total debt in FY2026 against $426M of owner earnings — roughly 3.8 years of owner earnings to retire it all. Balance-Sheet Safety scores it 77/100.

Put together: Balance-Sheet Safety is the strongest of the five filters (77/100) and Pricing Power the weakest (31/100), which is how WMS lands at 63/100 — a Narrow 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.

Common questions about WMS

Does ADVANCED DRAINAGE SYSTEMS, INC. have an economic moat?
Based on its FY2026 SEC filings, the Moat Index scores ADVANCED DRAINAGE SYSTEMS, INC. (WMS) 62.7 out of 100 — a Narrow 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 70, pricing power 31, returns on capital 75, balance-sheet safety 77, capital allocation 60.
Is WMS trading below the conservative owner-earnings estimate?
The value if growth stopped today — a zero-growth baseline — is $68.85 per share. It capitalizes normalized owner earnings at a 9% rate and assumes 0% growth. Versus a recent price of $141.84, that is 106% 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 WMS's Moat Score changed over time?
The record logs 16 readings since Jul 17, 2026; the latest reads 62.7 out of 100 (narrow 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.
