Unitranche is a debt structure that combines what would otherwise be separate senior and subordinated loans into a single facility, documented in one credit agreement and priced at one blended interest rate. Instead of a borrower negotiating a senior loan and a separate mezzanine tranche with different lenders and terms, a unitranche delivers the whole debt package in one instrument — typically from a single private-credit (direct) lender or a small club of them. It has become a dominant form of financing in mid-market leveraged buyouts.
How it works
From the borrower's perspective, a unitranche is one loan, one rate, one set of documents, one lender to deal with. The blended rate falls between what cheap senior debt and expensive mezzanine would each cost — the borrower pays more than pure senior but less than a senior-plus-mezz blend's headline mezz rate, in exchange for simplicity and speed.
Behind the scenes, however, the lenders often re-create the senior/junior split among themselves through an Agreement Among Lenders (AAL): the single facility is privately divided into a "first-out" piece (effectively senior, paid first) and a "last-out" piece (effectively subordinated, higher-yielding). The borrower sees one loan; the lenders allocate risk and return between first-out and last-out behind the curtain.
Why borrowers and sponsors like it
- Speed and certainty. One lender and one document means faster execution and fewer parties to align — a major advantage in a competitive deal process where the ability to close quickly and reliably wins auctions.
- Simplicity. A single rate and a single creditor simplify both the negotiation and ongoing administration (no inter-creditor disputes for the borrower to manage).
- Flexibility. Direct lenders offering unitranche can be more flexible on structure, covenants and hold size than syndicated bank markets, and can underwrite the entire debt amount themselves.
The rise of private credit
Unitranche grew up alongside the expansion of private credit / direct lending funds, which raised large pools of capital to lend directly to mid-market companies — stepping into space banks retreated from after the financial crisis. For a sponsor financing a buyout, a unitranche from a direct lender offers a one-stop, fully-committed debt solution. The trade-offs are a higher blended cost than a bank-led senior facility and reliance on a single relationship, but for many mid-market LBOs the speed and certainty are decisive.
