The five investor questions
2021–2025 (latest 5 aligned FYs; v3 window cap 5): revenue $10.7B to $9.1B, decreasing; diluted EPS 5.36 to 6.77, increasing.
Median gross margin 27.8% over 10y, stable.
Median ROIC 29.2%, above the 12% hurdle in 70% of years.
Net debt/EBITDA 1.9x, interest coverage 6x.
Owner earnings changed +13.3%/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.
- $1.3B
- $68.65
- $68.65
- $851.69
- 1141% above value if growth stopped today
What today’s price assumes: owner earnings growing ~65%/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.

18 years of fundamentals
The business, in plain English
Seagate Technology Holdings plc booked $9.1B of revenue in FY2025 in the Technology sector and kept 35.2% of it as gross profit — a solid-margin business by that measure. After every other cost, 16.1% of each revenue dollar reached the bottom line.
Across the filed record, revenue shrank from $9.8B (FY2009) to $9.1B (FY2025) — about −0.5% a year compounded over 16 years.
It earned 49.6% on invested capital in the latest filed year, FY2025. Across the full 17-year measurable filed record, median ROIC was 31.4%. Over the v3 recent window (10 measurable filed years), median ROIC was 29.2%. The Returns on Capital filter above scores it 90/100.
The balance sheet carried $5.0B of total debt in FY2025 against $1.5B of owner earnings — roughly 3.4 years of owner earnings to retire it all. Balance-Sheet Safety scores it 38/100.
Put together: Capital Allocation is the strongest of the five filters (100/100) and Pricing Power the weakest (34/100), which is how STX lands at 62/100 — 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.
Gaps in a line mean that item isn’t in STX’s 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 Aug 19, 2026.
184 filings were skipped because the SEC primary document returned 404; the omission is disclosed and aggregates are withheld.

Track record
How Seagate Technology Holdings plc’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.
How to read this: each dot is what the engine would have scored STX 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, STX 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 STX
- Does Seagate Technology Holdings plc have an economic moat?
- Based on its FY2025 SEC filings, the Moat Index scores Seagate Technology Holdings plc (STX) 62.2 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 49, pricing power 34, returns on capital 90, balance-sheet safety 38, capital allocation 100.
- Is STX trading below the conservative owner-earnings estimate?
- The value if growth stopped today — a zero-growth baseline — is $68.65 per share. It capitalizes normalized owner earnings at a 9% rate and assumes 0% growth. Versus a recent price of $851.69, that is 1141% 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 STX's Moat Score changed over time?
- The record logs 16 readings since Jul 17, 2026; the latest reads 62.2 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.
