Exit Multiple Method

Terminal value usually accounts for 60-80% of a DCF's total value, so the method you pick matters enormously. The exit multiple approach takes the final year of your explicit forecast — say Year 5 EBITDA — and multiplies it by an assumed exit multiple, most commonly EV/EBITDA, sometimes EV/EBIT or a revenue multiple for early-stage companies. The multiple is chosen to reflect where the business would trade at maturity, usually anchored to current comparable companies analysis trading multiples (often held flat, or modestly discounted to reflect a more mature growth profile). The resulting terminal value is then discounted back to the present at the discount rate, just like the interim cash flows.

The two terminal-value methods answer the same question differently. The exit multiple method is MARKET-BASED — it says 'a buyer would pay X times EBITDA,' which is intuitive for bankers and essential in LBOs where the sponsor literally plans to sell. The Gordon Growth Model is INTRINSIC — it grows the final unlevered free cash flow at a perpetual rate g and divides by (WACC − g). Best practice is to cross-check: compute terminal value both ways and confirm they're in a reasonable range. A useful sanity check is to back into the IMPLIED perpetuity growth rate from your exit multiple — if it implies 6% perpetual growth, your multiple is too high; mature companies should imply 2-3%.

The exit multiple method is the default terminal-value approach in leveraged buyout models because the entire LBO thesis is buy-improve-sell, and the exit multiple drives the sponsor's internal rate of return and MOIC. Its main weakness is circularity and subjectivity: you're using a present-day market multiple to value a business 5-10 years out, importing today's market sentiment into the distant future. A common refinement is to assume exit at the SAME multiple you bought at (no multiple expansion) to be conservative — taking credit for multiple expansion is one of the quickest ways to flatter a return that real-world investment committees will challenge.
