Leverage is the amount of debt used to fund an acquisition, usually expressed in turns of EBITDA (Net Debt/ EBITDA). It is the defining feature of a buyout: the debt lets a sponsor acquire a business far larger than its equity check alone would allow, and it magnifies the return on that equity in both directions.
Why it matters
Debt amplifies equity returns. The more of the purchase funded with debt, the smaller the equity check and the higher the return on that equity if the deal performs. It also raises risk, because interest and amortization are fixed claims that must be paid in good years and bad. Leverage is only safe to the extent free cash flow can service it through a downturn.
Turns and the equity check
Buying the $150M case study with $80M of gross debt is 3.2x leverage (80 / 25), 3.0x net of $5M cash, and funds just over half of enterprise valuewith debt, leaving an $80M sponsor equity check. Each turn of leverage is roughly $25M of extra debt capacity, and a smaller equity check, at the cost of a heavier fixed burden.
The common mistake
Sizing leverage off headline EBITDA without stress-testing free cash flow. Debt is only as safe as the cash that services it, so a disciplined model checks coverage through a downturn rather than maximizing turns.
