Acquisition Financing Structures for Mid-Market Sponsors
Mid-market acquisitions rarely close on a single loan product. The work is to match a small set of financing structures to the sources and uses, the target's cash flow and collateral, and what the seller will actually accept. Financely is an advisor and arranger, not a lender. Any facility is subject to lender credit approval, diligence on the target, and the quality of the file.

Start with sources and uses, not with a product name
A clean sources-and-uses table forces the structure into the open: purchase price, refinance of existing debt, transaction costs, and any day-one working capital or capex. Against that, you place equity, rollover, debt and any seller paper. If those lines do not add up, shopping term sheets will not fix it. For a practical walk-through of that table, see sources and uses in acquisition financing.
The structures below are the ones mid-market sponsors and independent buyers use most often. They can be combined. They should not all be used at once without a reason. For the mandate path once a structure is clear, see U.S. business acquisition financing.
Common structures at a glance
| Structure | What it usually does | What to watch |
|---|---|---|
| Senior term loan and revolver | Pays most of the funded debt at close and leaves a line for working capital | Covenants, borrowing-base tests if the revolver is asset-based, and room for add-ons |
| Delayed-draw term loan | Holds committed capacity for a planned capex program or a signed add-on | Commitment conditions, expiry of the draw window, and unused-line economics |
| Unitranche | Combines senior and junior debt into one facility with one set of documents | Blend of risk in one lender group, and how first-out or last-out arrangements are written if they exist |
| Seller note | Fills a gap the buyer will not, or cannot, fund in cash at close | Subordination, interest that is current versus accrued, and seller consents after closing |
| Mezzanine or preferred equity | Adds junior capital when senior capacity and seller paper still leave a hole | Covenants, equity kickers, and how this layer interacts with the senior documents |
| Rollover equity | Keeps management or the seller invested in the combined company | Valuation of the rollover, governance rights, and alignment on the exit |
| Earnout | Defers part of the price to future performance | Measurement, dispute rights, and whether lenders will count it as debt |
| Closing bridge | Covers a short gap until term debt or equity can be funded | A specific take-out, not an open-ended hope that permanent debt will appear |
None of these is a guaranteed path to a closing. Lenders and sellers make their own decisions. Financely does not set pricing, hold equity, or promise that a particular mix will be available.
Senior term loan and revolving credit
The baseline mid-market stack is still a funded term loan plus a revolving line. The term loan takes out the purchase price, or most of it. The revolver supports working capital after close, and in some deals it is also drawn at closing. The revolver may be a cash-flow line or an asset-based line if the target's collateral is the better underwriting story.
This structure is usually the right starting point when the target has a history of cash generation, a clear quality of earnings, and a use of proceeds that a senior lender can monitor. It is the wrong starting point when the model only works if every aggressive add-back is accepted, or when the buyer has not decided how add-on acquisitions will be funded later. When the gap above conventional senior debt is limited and the buyer wants to stay inside one senior facility, see what stretch senior financing is.
Delayed-draw capacity
A delayed-draw term loan is committed at closing but funded later, usually for a named capex program or a signed add-on. It keeps the buyer from over-borrowing on day one, and it keeps a lender already in the file for the next step. The draw is not automatic. Conditions, a draw expiry date, and a clear plan belong in the documents.
If the "delayed" piece is really just hope that a future deal will appear, it will not help you in a process. Write the identified use, or leave the capacity out and plan a later amendment.
Unitranche facilities
A unitranche replaces a senior loan plus a junior layer with one facility and, usually, one credit agreement. It can reduce intercreditor negotiation and give the sponsor a single lender relationship through integration. It is not automatically cheaper or more flexible than a layered stack. For the definition, see unitranche loan definition in private credit. For a comparison with a senior-plus-mezzanine stack, see unitranche vs senior plus mezzanine.
Use a unitranche when speed and a single document set matter, and when the leverage you need sits in the range those lenders actually hold. Use a layered senior stack when you want a bank or cash-flow revolver in the first-out position and a different capital provider behind it.
Seller notes, rollover equity and earnouts
Not every gap should be filled with more institutional debt. A seller note can close a valuation gap, keep the seller partially exposed to the business, and reduce the cash the buyer must raise. Rollover equity does similar work on the equity line: the seller or management keeps a stake and stays aligned with the plan. An earnout defers part of the price to future performance when the parties cannot agree on a number today.
Lenders will read all three carefully. A seller note is usually subordinated and may be limited in when it can be paid. An earnout can look like extra leverage if the definition is loose. Rollover is not free equity if the valuation is aggressive. These tools work when they are documented clearly and sized to a plan the senior lenders can live with.
Other layers that sometimes sit in the stack
Some acquisitions also use junior or holding-company layers when the operating-company debt cannot carry the whole uses column. Those are specialist structures, and they should not be the headline of a mid-market process unless the sources and uses truly require them. If that is your situation, read the separate notes on holdco financing and second lien financing rather than forcing those terms into this typology. For a definition of holdco back-leverage in the CRE and infrastructure setting, see what holdco back-leverage is. For how a FILO tranche differs from a second-lien loan, see FILO tranche vs second lien.
Bridges used only to reach a closing date
A short-term loan can cover the period between signing and the date term debt or equity can be funded. That only works if the take-out is specific. An open-ended bridge used to avoid a weak term-loan file is a different, and usually worse, idea. For acquisition bridges as a product, see bridge capital for business acquisitions.
How sponsors and independent buyers should use this list
Independent sponsors, search-style buyers and rollover management teams often need more than one of these structures in the same close. The constraint is usually equity and seller alignment, not a shortage of product names. For that path, see independent sponsor acquisition financing. Buy-and-build programs should also look at roll-up acquisition financing for buy-and-build sponsors, because delayed-draw and incremental capacity matter more in those deals.

Frequently asked questions
What are the main acquisition financing structures for mid-market deals?
Most mid-market stacks combine a senior term loan and a revolver, and then add delayed-draw capacity, a unitranche, a seller note, mezzanine, rollover equity or an earnout as the sources-and-uses require. The right mix depends on cash flow, collateral, and what the seller will accept. Financely is an advisor and arranger, not a lender.
Is a unitranche always better than a senior loan plus another layer?
No. A unitranche can simplify the closing and the lender relationship. A layered stack can be cheaper or more flexible for a later add-on, depending on the credit. Compare documentation, covenants and the plan after closing, not only the headline structure.
Can a buyer finance an acquisition without using all cash?
Often yes, if the target can support debt and the equity, rollover and any seller paper are credible. There is no standard mix, and no structure is guaranteed to close. A sources-and-uses table should be drawn before a lender process starts.
Does Financely lend to buyers or sponsors?
No. Financely is an advisor and arranger. We help structure the stack, prepare the file and run a lender process. The lender makes the credit decision.
