Discount free cash flow to the firm at the WACC, add a terminal value for the years beyond the explicit horizon, and you get enterprise value. Subtract net debt to reach equity value, then divide by shares for the per-share figure. Watch how much of the answer the terminal value alone carries.
In the TV-heavy case the narrow WACC − g_T gap pushes almost the whole value into the terminal value. That fragility is why analysts stress-test g_T.
Cash, not accounting profit:FCFF is cash to all capital providers after reinvestment (roughly EBIT(1 − tax) + D&A − capex − ΔNWC), not net income or EBIT. Earnings accrue revenue and expense before cash actually moves, so a profitable firm can still have weak FCFF.
Reflect: when the terminal value is 80%+ of EV, the valuation rests less on the five years you forecast carefully and more on one perpetual-growth guess. Does a longer explicit horizon genuinely reduce that reliance, or does it just move the same uncertainty further out?
