Exit Multiple Expansion
Private Equity glossary · Paper LBOs & Returns Math
Definition
Increase in EV/EBITDA multiple at exit vs. entry, contributing to LBO equity returns alongside EBITDA growth and debt paydown. From the return bridge E_1 - E_0 = m_0(EBITDA_1 - EBITDA_0) + EBITDA_1(m_1 - m_0) + (D_0 - D_1), multiple expansion contributes EBITDA_1 × (m_1 - m_0). Post-2008 analysis: for the large-cap segment, multiple expansion has been the dominant LBO return driver, reflecting a secular decline in interest rates and re-rating of the buyout-eligible universe. Going forward, with rates normalized and multiples elevated, sponsors increasingly emphasize operational value creation as the sustainable source of returns.
Exit Multiple Expansion in plain English
Exit multiple expansion means selling a company at a HIGHER valuation ratio than you paid for it — buying at, say, 8x its yearly profits and selling at 11x — which boosts your return even if nothing else changed. Investors value companies as a multiple of their earnings (EBITDA is roughly a company's yearly operating profit), so a bigger multiple means each dollar of profit is worth more when you sell. It's like buying a baseball card for 8 times its 'book value' and later selling it for 11 times, purely because collectors are now willing to pay more. Historically much of big buyout profit came from this — but it's largely luck of the market (interest rates falling made everything pricier), so smart investors now push to earn returns the reliable way: actually growing the business.
