Inputs from the filings
Three sets of assumptions
| Case | Growth yrs 1-5 | Discount rate | Value per share | Value vs price |

| Base | 6.5% | 9.0% | $78.68 | +47% |

Sensitivity: base case value per share
| 1.5% | 2.0% | 2.5% | 3.0% | 3.5% | |
|---|---|---|---|---|---|
| 7.0% | $103.60 | $111.22 | $120.52 | $132.15 | $147.10 |
| 8.0% | $85.00 | $89.94 | $95.77 | $102.77 | $111.33 |
| 9.0% | $71.41 | $74.78 | $78.68 | $83.22 | $88.59 |
| 10.0% | $61.05 | $63.45 | $66.17 | $69.28 | $72.87 |
| 11.0% | $52.91 | $54.67 | $56.63 | $58.84 | $61.35 |
Where the presets come from
Base: years 1 to 5 grow at PENTAIR plc's revenue growth rate over the last 5 fiscal years (6.7% a year), held between -5% and 15%. Years 6 to 10 grow halfway between that and the long-run rate of 2.5%. Future cash is discounted at 9% a year.
Bear: 5 points less growth, 2% long-run growth, 10% discount rate. Bull: 5 points more growth (at most 25%), 3% long-run growth, 8% discount rate.
Value per share = (present value of 10 years of free cash flow + present value of everything after + cash - debt) / diluted shares.
This is a model run on assumptions, not a recommendation or a price target. Small changes in the discount rate or growth move the result a lot, as the table above shows. Change them yourself in the calculator.
