The five investor questions

44

2021–2025 (latest 5 aligned FYs; v3 window cap 5): revenue $455M to $546M, increasing; diluted EPS -0.36 to -0.40, decreasing.

19

Median gross margin 11.3% over 9y, stable.

5

Median ROIC -0.8%, above the 12% hurdle in 14% of years.

28

Net debt/EBITDA n/ax, interest coverage -0x.

52

Owner earnings changed +4.9%/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
21% above value if growth stopped today
$21.5M

$11.77
$14.21
21% above value if growth stopped today

What today’s price assumes: owner earnings growing ~4%/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.

This is a disclosed model range, not intrinsic value as fact.

9 years of fundamentals

The business, in plain English

Mayville Engineering Company, Inc. booked $546M of revenue in FY2025 in the Industrials sector and kept 9.9% of it as gross profit — a thin-margin business by that measure. After every other cost, −1.5% of each revenue dollar reached the bottom line.

Across the filed record, revenue grew from $313M (FY2017) to $546M (FY2025) — about 7.2% a year compounded over 8 years.

It earned −1.3% on invested capital in the latest filed year, FY2025. Across the full 7-year measurable filed record, median ROIC was −0.8%. Over the v3 recent window (7 measurable filed years), median ROIC was −0.8%. The Returns on Capital filter above scores it 5/100.

MEC's latest filed year, FY2025, 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: Capital Allocation is the strongest of the five filters (52/100) and Returns on Capital the weakest (5/100), which is how MEC lands at 30/100 — 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.

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 MEC.

Track record

How Mayville Engineering Company, Inc.’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 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 MEC on that December 31; the line below is its total-return price path (dividends reinvested) in the years since.

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, MEC 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 MEC

Does Mayville Engineering Company, Inc. have an economic moat?
Based on its FY2025 SEC filings, the Moat Index scores Mayville Engineering Company, Inc. (MEC) 29.5 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 44, pricing power 19, returns on capital 5, balance-sheet safety 28, capital allocation 52.
Is MEC trading below the conservative owner-earnings estimate?
The value if growth stopped today — a zero-growth baseline — is $11.77 per share. It capitalizes normalized owner earnings at a 9% rate and assumes 0% growth. Versus a recent price of $14.21, that is 21% 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 MEC's Moat Score changed over time?
The record logs 28 readings since Jul 17, 2026; the latest reads 29.5 out of 100 (no 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.

Scored from primary SEC filings via the public methodology. Educational only — not a recommendation to buy or sell MEC. See the disclaimer.
