Side by side · every name on one set of axes
Growth against the P/E multiple. Up and to the right is cheaper and faster — the quality-growth idea in one picture. Points beyond the axis are pinned to the edge and marked off-scale rather than allowed to compress everything else.

The companies
EROCERock, Inc.
Why now
Specialty Industrial Machinery · market cap $3.9b. Down 32% from 52-week high of $20.70 — deep drawdown territory. Revenue growing +43% — in hypergrowth territory. PEG 0.22 — paying under fair value for the growth rate. 8 sell-side analysts rate this a Strong Buy with a mean 1-yr target of $22.88 (implying +62% upside).
Moat
Moat signals from the quantitative card are modest — profitability and capital efficiency are middle-of-pack. The thesis here depends on softer factors (switching costs, brand, distribution, regulatory protection) not captured by the quality-growth screen.
Risk
Trailing P/E 50.5x prices in sustained high growth — any quarter that disappoints triggers sharp re-rating. Currently unprofitable (margin -66.7%) — path to GAAP profitability is the core thesis risk. Down 32% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up.
PNRPentair plc
Why now
Specialty Industrial Machinery · market cap $10.3b. Down 43% from 52-week high of $113.95 — deep drawdown territory. 14 sell-side analysts rate this a Buy with a mean 1-yr target of $76.64 (implying +19% upside).
Moat
Net margin 16% beats the market median by a meaningful margin — the company is keeping more of every revenue dollar than the average S&P constituent. ROE 18% sits above Buffett's preferred 15% threshold — the equity base is compounding at a rate the market struggles to discount accurately. FCF converts 107% of net income — earnings translate cleanly into cash, a sign that working capital and capex are well-disciplined.
Risk
Down 43% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up.

Where EROC and PNR diverge
On the headline score the gap is 1.9 points in favor of EROC. They get there differently, though — each leads on a different pillar, so the better pick depends on which you weight.

Pillars run 0–100 against sector peers, so a score is a statement about a company relative to its own industry rather than to the other name here. A wide Value gap usually means the market already prices the difference in quality or growth — which is the trade-off this comparison comes down to.
