Sensitivity: base case value per share
| 1.5% | 2.0% | 2.5% | 3.0% | 3.5% | |

| 8.0% | $330.72 | $348.35 | $369.18 | $394.18 | $424.74 |
| 9.0% | $282.51 | $294.56 | $308.47 | $324.69 | $343.87 |

Where the presets come from
Base: years 1 to 5 grow at Idexx Laboratories Inc's revenue growth rate over the last 5 fiscal years (9.7% 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.
