Terminal P/E

Terminal P/E is the exit P/E multiple applied to the final-year EPS in a five-year forward-earnings valuation. It is the single largest assumption in such models and the most common place where an analyst either compounds optimism (using a terminal multiple equal to today's premium multiple) or compounds pessimism (using a multiple too far below the company's quality-justified steady state). Our discipline is to anchor terminal P/E to (a) the archetype the business will most plausibly resemble at the end of the forecast horizon, (b) the long-run margin and growth profile implied by the explicit forecast, and (c) the prevailing risk-free rate environment. A 15% grower at 25x today should not be valued at a 25x terminal P/E unless we believe it will still be growing 15% in year ten — which is rare. More commonly we step the multiple down to a 18–22x range as growth normalizes, reflecting the reality that even excellent businesses converge toward GDP-plus growth over long horizons.
