The five investor questions
2021–2025 (latest 5 aligned FYs; v3 window cap 5): revenue $3.8B to $4.2B, increasing; diluted EPS 3.30 to 3.96, increasing.
Median gross margin 35.2% over 10y, very stable.
Median ROIC 16.8%, above the 12% hurdle in 80% of years.
Net debt/EBITDA 1.6x, no material interest expense disclosed.
Owner earnings changed +3.1%/yr over up to the ten most recent annual observations, share count n/a.
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.
- $662M
- Unavailable — insufficient owner-earnings data
- Unavailable — insufficient growth-model data
- $62.88
- No price data
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.

19 years of fundamentals
The business, in plain English
Pentair plc booked $4.2B of revenue in FY2025 in the Industrials sector and kept 40.5% of it as gross profit — a solid-margin business by that measure. After every other cost, 15.7% of each revenue dollar reached the bottom line.
Across the filed record, revenue grew from $3.4B (FY2008) to $4.2B (FY2025) — about 1.3% a year compounded over 17 years.
It earned 13.6% on invested capital in the latest filed year, FY2025. Across the full 18-year measurable filed record, median ROIC was 9.6%. Over the v3 recent window (10 measurable filed years), median ROIC was 16.8%. The Returns on Capital filter above scores it 79/100.
The balance sheet carried $1.6B of total debt in FY2025 against $703M of owner earnings — roughly 2.3 years of owner earnings to retire it all. Balance-Sheet Safety scores it 78/100.
Put together: Returns on Capital is the strongest of the five filters (79/100) and Capital Allocation the weakest (49/100), which is how PNR lands at 67/100 — 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 PNR’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.

Scores are logged append-only and never overwritten — this record cannot be reconstructed retroactively, which is exactly why it’s worth keeping.
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 PNR.
Track record
How Pentair 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 PNR 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 1 year PNR rated Wide-moat (2024), the median forward total return that followed — measured only after each year’s filings were public — was:
- 1 year 6% vs the S&P 500’s 17% (price basis) · median over 1 year
- 3 years None of the 1 year it rated Wide has a fully elapsed 3-year window with a benchmark to compare against yet.
- 5 years None of the 1 year it rated Wide has a fully elapsed 5-year window with a benchmark to compare against yet.
These are medians computed from the data, not a claim about any one year. The company figures are total returns (dividends reinvested); the S&P 500 is the price-only ^GSPC index, which excludes dividends and so understates the index — the gap flatters the company. A quality rating is not a return forecast, and past returns don’t predict future ones. Educational only, not investment advice.
