Pentair plc (PNR) valuation and DCF model

What the price implies · reverse DCF

At $68.70 the price implies free cash flow after share-based pay growing 5.8% a year for ten years.

Free cash flow after share-based pay grew −0.3% a year over the last ten years, 9.6% over the last five. The price asks for 6.1 points a year more than its ten-year rate. The industry’s median company is priced for 10.4%.

In December 2017 the price assumed 2.6% a year; Pentair plc went on to grow free cash flow after share-based pay 3.4% a year to FY2025.

Price implies: 5.8%
Last 5 years, reported: 9.6%
Last 10 years, reported: −0.3%
Industry median implies: 10.4%

The headline discounts the last twelve months’ free cash flow after share-based pay at 9.0% for ten years and grows it 2.5% a year after that, the same for every company, so the figure compares across the market (how a reverse DCF works).

The other way round · DCF

The price needs: 5.8% a year for ten years; $68.70; today’s price
Its base case: −0.3% a year for five years, then −0.2%; $40.39; 41.2% below today’s price

Both are growth in free cash flow after share-based pay, discounted at 9.0%, with 2.5% a year after year ten.

1 · Cash flow to equity

Subtract share-based pay ($0.03 billion)

Growth, yrs 1–5 (%)

Growth, yrs 6–10 (%)

Yearly growth in cash flow. It usually slows as the company matures.

Today’s price implies free cash flow after share-based pay growing 5.8% a year for ten years.

2 · Rates

Cost of equity (%)

Terminal growth (%)

Cost of equity is the yearly return shareholders require, typically 8–11%. Terminal growth is growth forever after year 10, usually near long-run inflation, 2–3%.

Every growth rate on this page is the business’s — its cash flow, FFO or dividend — never its share price’s. A discounted-cash-flow model is only as good as its assumptions. Figures from the 10-K and 10-Q filings. Not investment advice.
