Inputs from the filings
Three sets of assumptions
| Case | Growth yrs 1-5 | Discount rate | Value per share | Value vs price |
|---|---|---|---|---|
| Bear | -7.0% | 10.0% | $13.08 | -75% |
| Base | -2.0% | 9.0% | $20.07 | -62% |
| Bull | 3.0% | 8.0% | $33.12 | -37% |
Sensitivity: base case value per share
| 1.5% | 2.0% | 2.5% | 3.0% | 3.5% | |
|---|---|---|---|---|---|
| 7.0% | $24.84 | $26.25 | $27.99 | $30.15 | $32.94 |
| 8.0% | $21.31 | $22.23 | $23.31 | $24.62 | $26.21 |
| 9.0% | $18.72 | $19.35 | $20.07 | $20.92 | $21.92 |
| 10.0% | $16.73 | $17.18 | $17.69 | $18.27 | $18.93 |
| 11.0% | $15.16 | $15.49 | $15.86 | $16.27 | $16.74 |
Where the presets come from
Base: years 1 to 5 grow at Power Integrations Inc's revenue growth rate over the last 5 fiscal years (-1.9% 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.
