Discounted Cash Flow — intrinsic-valuation method that values a business as the present value of projected unlevered free cash flows plus a terminal value, discounted at WACC: EV_DCF = sum_t=1^N (UFCF_t)/((1+WACC)^t) + (TV_N)/((1+WACC)^N). Terminal value computed via either Perpetuity Growth Method (TV = UFCF_N+1 / (WACC - g)) or Exit Multiple Method (TV = EBITDA_N × Exit Multiple); the two should be cross-checked. In PE, DCF is used as a valuation cross-check alongside trading comps, precedent transactions, and the LBO walk-away price.
