| Base | 4.0% | 9.0% | $48.27 | -29% |

Sensitivity: base case value per share
| 1.5% | 2.0% | 2.5% | 3.0% | 3.5% | |
|---|---|---|---|---|---|
| 7.0% | $59.85 | $63.37 | $67.67 | $73.04 | $79.95 |
| 8.0% | $51.22 | $53.50 | $56.20 | $59.43 | $63.39 |
| 9.0% | $44.91 | $46.47 | $48.27 | $50.37 | $52.85 |
| 10.0% | $40.09 | $41.20 | $42.46 | $43.89 | $45.55 |

Where the presets come from
Base: years 1 to 5 grow at Proto Labs Inc's revenue growth rate over the last 5 fiscal years (4.2% 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.
