Cost relative to bank debt. If the company could borrow everything it needs from a bank, the blended rate will usually be higher.
Prepayment premiums. Many loans charge a fee for paying off early in the first years.
Concentration. Relying on one lender means its view of the business carries a lot of weight in a downturn.
Hidden lender splits. A first-out and last-out arrangement can complicate decisions later.
All-or-nothing refinancing. It is harder to refinance just the cheaper piece of the debt when markets improve.
This structure tends to suit companies with steady, predictable cash flow and moderate capital needs. Common uses include:
Leveraged buyouts by private equity owners
Add-on acquisitions by an existing portfolio company
Recapitalizations that return capital to owners
Asset-light businesses, such as software or services, whose borrowing capacity is based on earnings rather than collateral
Lenders will review the same things they would for any loan sized on earnings: the quality and stability of EBITDA, customer concentration, the strength of management and the equity cushion beneath the debt. A meaningful equity contribution from the buyer gives the lender comfort that the owners share the risk.
It is less suited to companies that can borrow cheaply from a bank alone or that expect to refinance soon.
Is a unitranche loan senior or subordinated?
It is a senior secured loan from the borrower's point of view, holding a first lien on the collateral. Any internal ranking among the lenders is handled in their own agreement.
Who provides these loans?
Mostly private credit funds and other direct lenders, sometimes in clubs. Some banks participate or provide the revolving line that sits alongside.
How big do these loans get?
Sizes range widely, from deals for smaller middle market companies to very large financings for big private equity-backed businesses. The lender's fund size and hold limits set the practical ceiling.
For acquisitions and recapitalizations, a one-loan structure can save time and simplify the lender relationship, though it may cost more than bank debt. Compare it against a traditional split financing, then explore unitranche and other options that match your company's cash flow and growth plans.
Unitranche financing is a single loan that combines what would otherwise be separate senior and subordinated debt into one facility, with one interest rate, one credit agreement and one set of covenants. It is most often provided by private credit funds to mid-sized companies, especially to fund acquisitions.
The appeal is simplicity. Instead of negotiating with a bank on the senior loan and a mezzanine lender on the junior piece, the borrower deals with one lender or a small club of lenders acting together. That can speed up closing and reduce the risk that one part of the financing falls through.
A traditional split financing has two or more layers, each with its own lender, pricing, documents and rights. The one-loan approach collapses those layers:
One amount. The full debt package is lent under a single credit agreement.
One blended rate. The interest rate sits between what a senior loan and a junior loan would cost on their own.
One set of covenants. Financial tests, reporting and restrictions are negotiated once.
One lien. The lender or lending group takes a single security interest in the company's assets.
The name reflects the idea. "Tranche" is French for slice, and a unitranche loan has a single slice of debt instead of several.
Many of these loans come with a separate revolving line of credit for working capital, which is sometimes provided by a bank and given priority over the term loan.
When more than one lender participates, the lenders may divide the loan among themselves behind the scenes. Under an agreement among lenders, one group takes a "first-out" piece that is repaid first and earns a lower rate, while another takes a "last-out" piece that is repaid later and earns more.
The borrower usually pays one rate and sees one loan. The split matters mostly to the lenders, but it can affect the borrower when the company needs an amendment or runs into trouble, because the lender groups may have different interests. Ask early whether such an arrangement exists and who controls key decisions.
Consider a company that needs $40 million to finance an acquisition. These rates are hypothetical, chosen only to show the math.
Split structure. A $28 million senior loan at 8% costs $2.24 million a year in interest. A $12 million subordinated note at 13% costs $1.56 million. Total interest is $3.8 million, a blended rate of 9.5%.
Single loan. A $40 million loan at 9.75% costs $3.9 million a year in interest.
In this example, the single loan costs $100,000 more in annual interest. In return, the company negotiates one set of documents, deals with one lender relationship, avoids an intercreditor agreement and may close sooner. In real markets, the blended rate can land above or below the combined cost of a split structure, so compare actual quotes.
Speed. Fewer parties and one document set often mean a faster closing.
Certainty. A single committed lender reduces the risk of a funding gap at closing, which sellers value in a competitive sale.
Simpler amendments. Changes need agreement from one lender or group, not several with competing interests.
Higher leverage. Total borrowing can exceed what a bank alone would provide.
Less amortization. Many such loans require only modest scheduled principal payments, which leaves more cash for growth.
