| Base | 12.5% | 9.0% | $44.46 | +31% |

Sensitivity: base case value per share
| 1.5% | 2.0% | 2.5% | 3.0% | 3.5% | |
|---|---|---|---|---|---|
| 7.0% | $58.03 | $62.24 | $67.38 | $73.80 | $82.06 |
| 8.0% | $47.86 | $50.58 | $53.81 | $57.67 | $62.40 |
| 9.0% | $40.44 | $42.31 | $44.46 | $46.97 | $49.94 |
| 10.0% | $34.82 | $36.14 | $37.64 | $39.36 | $41.34 |
| 11.0% | $30.40 | $31.38 | $32.46 | $33.69 | $35.07 |
Where the presets come from
Base: years 1 to 5 grow at Tetra Tech Inc's revenue growth rate over the last 5 fiscal years (12.7% 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.
