In discounted cash flow (DCF) valuation techniques the value of the stock is estimated based upon present value of some measure of cash flow. Free cash flow to the firm (FCFF) is generally described as cash flows after direct costs and before any payments to capital suppliers.

Disclaimer!
Valuation is based on standard assumptions. There may exist specific factors relevant to stock value and omitted here. In such a case, the real stock value may differ significantly form the estimated. If you want to use the estimated intrinsic stock value in investment decision making process, do so at your own risk.

2021 Calculations
2 Interest expense, after tax = Interest expense × (1 – EITR)
= 253,600 × (1 – 3.00%)
= 245,992
3 EBIT(1 – EITR)
= Net income attributable to Biogen Inc. + Interest expense, after tax
= 1,556,100 + 245,992
= 1,802,092
4 RR = [EBIT(1 – EITR) – Interest expense (after tax) and dividends] ÷ EBIT(1 – EITR)
= [1,802,092 – 245,992] ÷ 1,802,092
= 0.86
5 ROIC = 100 × EBIT(1 – EITR) ÷ Total capital
= 100 × 1,802,092 ÷ 18,169,300
= 9.92%
6 g = RR × ROIC
= 0.94 × 20.63%
= 19.36%
FCFF growth rate (g) implied by single-stage model
g = 100 × (Total capital, fair value0 × WACC – FCFF0) ÷ (Total capital, fair value0 + FCFF0)
= 100 × (47,397,724 × 7.57% – 3,670,587) ÷ (47,397,724 + 3,670,587)
= -0.16%
where:
Total capital, fair value0 = current fair value of Biogen Inc. debt and equity (US$ in thousands)
FCFF0 = the last year Biogen Inc. free cash flow to the firm (US$ in thousands)
WACC = weighted average cost of Biogen Inc. capital
Year | Value | gt |
---|---|---|
1 | g1 | 19.36% |
2 | g2 | 14.48% |
3 | g3 | 9.60% |
4 | g4 | 4.72% |
5 and thereafter | g5 | -0.16% |
where:
g1 is implied by PRAT model
g5 is implied by single-stage model
g2, g3 and g4 are calculated using linear interpoltion between g1 and g5
Calculations
g2 = g1 + (g5 – g1) × (2 – 1) ÷ (5 – 1)
= 19.36% + (-0.16% – 19.36%) × (2 – 1) ÷ (5 – 1)
= 14.48%
g3 = g1 + (g5 – g1) × (3 – 1) ÷ (5 – 1)
= 19.36% + (-0.16% – 19.36%) × (3 – 1) ÷ (5 – 1)
= 9.60%
g4 = g1 + (g5 – g1) × (4 – 1) ÷ (5 – 1)
= 19.36% + (-0.16% – 19.36%) × (4 – 1) ÷ (5 – 1)
= 4.72%
