Which tranche typically carries the highest risk and highest expected return in PE financing, and why?

• A. Senior debt carries the highest risk and highest return due to priority.
• B. Revolver carries the highest risk.
• C. Mezzanine carries the highest risk.
• D. Equity carries the highest risk and highest potential return because it participates last in the capital structure and captures upside.

Answer: (B)

In private equity financing, risk and return align with a position in the capital stack: the deeper you are, the higher the potential upside but also the greater the risk. Equity sits at the bottom of the stack, behind all debt. If the business performs well and is sold for a high multiple or generates strong cash flows, equity holders capture most of the upside and can realize outsized returns. But if the company struggles, equity can lose the entire investment because debt must be paid first.

A revolving credit facility (the liquidity line) is a short-term tool lenders provide to fund working capital. It generates returns through interest and fees and carries a priority claim, but it does not participate in the company’s upside in the way equity does. It’s not designed to deliver the highest possible return, though it can be crucial for liquidity management.

Therefore, the tranche with the highest risk and highest potential return is the equity tranche.
