The five investor questions

12

2021–2025 (latest 5 aligned FYs; v3 window cap 5): revenue $1.7B to $1.4B, decreasing; diluted EPS 1.13 to -0.51, decreasing.

75

Median gross margin 44.2% over 10y, very stable.

7

Median ROIC -14.7%, above the 12% hurdle in 20% of years.

28

Net debt/EBITDA n/ax, interest coverage -109x.

24

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. SONO revenue fell in each of the three most recent year-over-year FY comparisons, so this estimate is flagged as unreliable for this company.

Among the current top-score group, the median current price is 240% above the zero-growth estimate across 49 of the current top 50 companies by Moat Score with both values.

11 years of fundamentals

The business, in plain English

SONOS, INC. booked $1.4B of revenue in FY2025 in the Industrials sector and kept 43.7% of it as gross profit — a solid-margin business by that measure. After every other cost, −4.2% of each revenue dollar reached the bottom line.

Across the filed record, revenue grew from $844M (FY2015) to $1.4B (FY2025) — about 5.5% a year compounded over 10 years.

It earned −22.1% on invested capital in the latest filed year, FY2025. Across the full 5-year measurable filed record, median ROIC was −14.7%. Over the v3 recent window (5 measurable filed years), median ROIC was −14.7%. The Returns on Capital filter above scores it 7/100.

SONO'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: Pricing Power is the strongest of the five filters (75/100) and Returns on Capital the weakest (7/100), which is how SONO lands at 29/100 — 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.

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.

Among the rows shown, A/F/M acquisition, payment or withholding, and exercise or conversion rows outnumber S sale rows (14 versus 3). 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 SONOS, 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 scores 2018–2025, 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 SONO on that December 31; the line below is its total-return price path (dividends reinvested) in the years since.

0406080100WideNarrowShallowNo moatPoint-in-time Moat Score100200Indexed price · log scale (2019 = 100)20182020202220242026

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, SONO 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 SONO

Does SONOS, INC. have an economic moat?
Based on its FY2025 SEC filings, the Moat Index scores SONOS, INC. (SONO) 28.9 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 12, pricing power 75, returns on capital 7, balance-sheet safety 28, capital allocation 24.
How has SONO's Moat Score changed over time?
The record logs 28 readings since Jul 17, 2026; the latest reads 28.9 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.
