Sensitivity: base case value per share
| 1.5% | 2.0% | 2.5% | 3.0% | 3.5% | |
|---|---|---|---|---|---|
| 7.0% | $194.02 | $207.33 | $223.60 | $243.94 | $270.09 |
| 8.0% | $161.48 | $170.11 | $180.31 | $192.55 | $207.52 |
| 9.0% | $137.69 | $143.59 | $150.40 | $158.35 | $167.74 |
| 10.0% | $119.57 | $123.77 | $128.53 | $133.96 | $140.24 |
| 11.0% | $105.32 | $108.40 | $111.84 | $115.71 | $120.09 |
Where the presets come from
Base: years 1 to 5 grow at American Tower Corp's revenue growth rate over the last 5 fiscal years (5.8% 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.
