Unitranche Financing: How It Works and Who Qualifies
Unitranche financing is a single loan that blends senior and junior (subordinated) debt into one facility, with one interest rate and one set of documents. It is mainly used by middle-market companies that want to fund growth, an acquisition or a recapitalization without juggling a separate first-lien and second-lien loan.
What unitranche financing means
In a traditional capital stack, a company might borrow a senior term loan from a bank and a mezzanine loan from another lender. Each has its own terms, its own lender and its own intercreditor agreement. A unitranche loan puts both layers into one facility. One lender, or a small group of lenders acting together, provides all of the debt.
The blended rate sits between what senior debt and junior debt would cost on their own. The borrower gets one rate and one payment schedule. The lenders sort out the priority between the layers in their own agreement, which the borrower usually does not negotiate directly.
How the structure works
A unitranche facility is typically documented in a single loan agreement. It is secured by the company's assets, and the lender has a first-priority claim on them. The junior portion is priced higher than a senior loan would be, and the overall blended rate reflects that mix.
The amortization is usually light. According to Regions, amortization rates are fixed and low, often about 1% per year, and the borrower deals with a single lender team. Most of the principal is repaid at maturity, so the company's cash flow goes further in the years before a refinancing or sale.
Unitranche vs. mezzanine vs. senior debt
The three options differ mostly in how many lenders are involved, how risk is layered and what the borrower pays.
| Feature | Senior term loan | Mezzanine debt | Unitranche |
|---|---|---|---|
| Number of loans | One senior loan | Separate junior loan | One combined loan |
| Lenders | Usually a bank or senior lender | Specialist junior lender | One lender or group |
| Rate | Lowest of the three | Highest of the three | Blended between the two |
| Priority | First lien | Subordinated, often unsecured or second lien | First-out and last-out split handled by lenders |
| Documentation | Senior credit agreement | Separate agreement and intercreditor terms | Single agreement |
| Borrower's simplicity | Lower, if mezzanine is also used | Lower | Higher |
The key difference between unitranche and mezzanine debt is that mezzanine is a separate junior loan that sits behind a senior lender. Unitranche merges that junior risk into the same loan as the senior debt. Mezzanine lenders often take equity-like features, such as warrants, which is less common in a unitranche.
Why companies choose it
The main reasons are simplicity, speed and certainty. Fewer lenders means fewer negotiations and fewer documents. A borrower facing one lender team can close faster than one assembling a senior bank loan and a mezzanine loan separately.
The structure also suits companies that do not fit neatly into a bank's lending box. A business with strong cash flow but limited hard collateral may find a bank senior loan too small. A unitranche lender may size the loan on cash flow instead.
The trade-off is cost. The blended rate is usually higher than a plain senior loan, and the lender's security and covenants can be tight. Borrowers should compare the all-in cost, including fees, prepayment terms and covenants, not just the headline rate.
Who typically uses unitranche debt
Unitranche loans are commonly used by middle-market borrowers. Regions describes them as typically attractive to borrowers with annual EBITDA under $50 million and sales under $500 million. Loan sizes vary. The same source says a typical loan would run about $100 to $200 million, so the product spans a wide range of deal sizes.
Common uses include:
- Funding an acquisition or a buyout
- Financing growth, such as new locations or equipment
- Recapitalizing a business and returning capital to owners
- Funding an ownership transition
The product has been around since the first decade of the 2000s and became more widely used after the 2007-2008 financial crisis and the credit crunch that followed, according to Regions.
The size of the market
Direct lending has grown quickly. According to Baker Donelson, industry estimates put middle-market issuances at a record $210 billion in 2024, up from $94 billion in 2023. That growth is one reason why more private lenders now offer unitranche loans and why borrowers have more choices than they once did.
How to choose a unitranche lender
Lenders differ in the markets they serve, the deal sizes they prefer and how they set covenants. A few points are worth checking before you accept a term sheet:
- Fit on size. Confirm the lender writes loans in your range, from the low millions to $100 million or more.
- Fit on earnings. Lenders set minimums for revenue and EBITDA. Check them before you apply.
- Fit on industry and state. Some lenders avoid certain sectors or only lend in particular states.
- All-in cost. Compare the rate, fees, amortization, prepayment penalties and any equity features.
- Covenants and flexibility. Read the financial tests and what happens if you miss one.
- Lender team. Ask who will manage the relationship after closing.
How Thrive Funding fits in
Thrive Funding is a private credit arranger for middle-market companies. It is not a lender, and the lender makes every credit decision. Borrowers apply once at thrivefunding.com/apply, and the application is matched against lending groups whose criteria fit the deal's size, revenue and EBITDA, industry, state, loan type and pricing.
Here is how the process runs:
- The application arrives as a lead.
- Thrive matches it against each lending group's criteria.
- Matching groups receive an anonymous deal summary and reply yes or no on whether it fits.
- Once the borrower agrees, up to three groups that said yes receive an introduction, best fit first. Each introduction is its own email thread.
- Lenders issue indicative terms on their own letterhead. Thrive sends the borrower a side-by-side summary, and the borrower chooses one.
Indicative terms are estimates, not a term sheet and not an offer. Thrive is paid by its lending partners. The lender pays Thrive a success fee when the loan closes, and borrowers should ask about any costs directly.
Thrive's site describes its focus as middle-market deals starting at $5 million and up to $100 million or more. The application form accepts requests from $1 million. Requests below $1 million receive an automatic decline.

FAQ
What is a unitranche in finance?
A unitranche is one loan that combines senior and subordinated debt into a single facility with one interest rate. The borrower deals with one lender or lender group and signs one loan agreement. The lenders handle how the layers are prioritized among themselves.
What are the key differences between unitranche debt and mezzanine debt?
Mezzanine is a separate junior loan that sits behind a senior lender, so the borrower has at least two loans and two sets of terms. Unitranche combines the senior and junior layers into one loan. Unitranche is usually simpler to manage, while mezzanine may be priced differently and sometimes includes equity features.
What is middle market lending?
Middle market lending is lending to mid-sized companies, which are larger than small businesses but smaller than the largest public companies. Loans are often arranged by private lenders rather than large banks. Regions notes that unitranche is commonly used by middle-market borrowers with annual EBITDA under $50 million.
What is a middle market loan?
A middle market loan is a loan made to a middle-market company. Examples include senior term loans, mezzanine debt and unitranche facilities. Size, structure and pricing vary by lender and by deal.
What is middle market direct lending?
Direct lending means a non-bank lender, often a private credit fund, makes the loan directly to the borrower without a syndicate of banks. Baker Donelson reports that middle-market issuances reached a record $210 billion in 2024, which reflects how much this market has grown.
