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.
