The five investor questions

20

2022–2026 (latest 5 aligned FYs; v3 window cap 5): revenue $383M to $280M, decreasing; diluted EPS -6.08 to -7.97, decreasing. 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%.

65

Median gross margin 40.6% over 10y, very stable.

—

Not enough years of ROIC data to score returns on capital.

28

Net debt/EBITDA n/ax, interest coverage -1x.

44

Owner earnings changed trend unclear over up to the ten most recent annual observations, share count n/a.

The returnsOnCapital component abstained: Not enough years of ROIC data to score returns on capital. The other four 20% weights were renormalized over the scored 80%.

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.

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.

18 years of fundamentals

The business, in plain English

QUANTUM CORP /DE/ booked $280M of revenue in FY2026 in the Technology sector and kept 36.9% of it as gross profit — a solid-margin business by that measure. After every other cost, −36.1% of each revenue dollar reached the bottom line.

Across the filed record, revenue shrank from $681M (FY2010) to $280M (FY2026) — about −5.4% a year compounded over 16 years.

The balance sheet carried $90M of total debt in FY2026. Balance-Sheet Safety scores it 28/100.

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.

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

Track record

How QUANTUM CORP /DE/’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 QMCO on that December 31; the line below is its total-return price path (dividends reinvested) in the years since.

0406080100WideNarrowShallowNo moatPoint-in-time Moat Score25102050100Indexed 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, QMCO 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.

Does QUANTUM CORP /DE/ have an economic moat?
Based on its FY2026 SEC filings, the Moat Index scores QUANTUM CORP /DE/ (QMCO) 39.2 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 20, pricing power 65, returns on capital not measurable from the filings, balance-sheet safety 28, capital allocation 44.
How has QMCO's Moat Score changed over time?
The record logs 15 readings since Jul 17, 2026; the latest reads 39.2 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.
