Private credit and mezzanine debt play an increasing role in lower middle market deal structures. How mezz fits, what returns look like, and what Berkman Woods looks for in a lending partner.
Mezzanine debt is the middle seat on a long flight. Nobody's first choice. But sometimes it is the only seat that gets you where you need to go, and it usually has a better view than coach.
Most business owners who have never needed it hear the word "mezzanine" and picture something from a hotel lobby. Some floor between the lobby and the real floors. That is, actually, not a terrible analogy for what it does in a capital structure. It sits between the senior debt and the equity. It is not glamorous. It is structural. And I have seen deals that would not have closed without it.
Here is how mezz works in lower middle market transactions, what it costs, and when it makes sense.
Three layers. Senior debt at the top, SBA 7(a) or conventional bank, secured by business assets. Mezzanine debt in the middle, subordinated to senior and senior to equity. Equity at the bottom, first to absorb losses, last to receive proceeds, and with the highest return potential.
Mezz is subordinated, meaning it gets paid after senior lenders in a default scenario. That additional risk commands a yield premium. Typical mezz returns in LMM transactions run 12 to 16% total, combining cash interest, PIK interest, and warrant coverage. The price reflects the position, not a punitive judgment on the borrower.
I have seen deals almost fall apart because senior debt alone was not enough. The business was good. The buyer was right. The thesis was clear. But the SBA cap or the goodwill structure created a gap that equity could not fill without diluting the return past the point of anyone's interest. The mezz piece closed that gap. The deal happened. Everyone went home satisfied.
Three primary situations where mezz shows up. Deals where SBA alone does not cover the full financing need, typically because the goodwill portion of the purchase price exceeds the SBA cap or because the deal includes working capital requirements the SBA loan does not touch. Deals above the SBA goodwill threshold where supplemental private capital bridges the financing gap. And situations where the equity sponsor wants to optimize the equity return by using additional leverage without the operational requirements that come with SBA.
Cash flow coverage. On a fully loaded basis including both senior and mezz debt service, coverage should be positive, typically 1.0x or better. That is the floor, not the target. Strong deals show 1.2x or higher on total debt service. If the number is sitting right at 1.0x, everybody in the room knows it.
Business quality. Recurring revenue, diversified customer base, essential services, stable management team. Mezz lenders are taking on junior risk, so they want to see businesses where the senior lender is also highly confident. If the bank is nervous, the mezz lender should be more nervous.
Sponsor quality. The independent sponsor's operating capability and track record matter as much as the deal itself. A well-run business acquired by an inexperienced sponsor is riskier than the business quality alone would suggest. The lender is betting on both the business and the operator.
Exit optionality. A clear path to refinance or recapitalize within 3 to 5 years. Is there a strategic buyer universe? Could the business support a conventional refinancing in two years? Mezz lenders are not looking for permanent capital. They are looking for a defined exit.
Mezz lenders often receive warrants representing 1 to 5% equity in the acquiring entity. This participation gives them upside if the business is sold at a premium. It is the lender's acknowledgment that they are taking equity-like risk, and they want a piece of the equity-like reward.
The warrant percentage is negotiated based on the risk profile of the deal, the yield concession the borrower is receiving, and the lender's view on exit value. On deals where meaningful value creation is expected, warrants can substantially enhance total return above the stated interest rate. That is the trade. Price for the risk, participate in the upside.
Speed. SBA timelines are defined. When mezz is part of a deal structure, it needs to move alongside SBA diligence. A lender who needs eight weeks to issue a term sheet is not a fit for a 60-day close process.
Flexibility. LMM deal structures are rarely identical. A lender who can adapt to deal-specific circumstances, seller note structures, earnouts, working capital adjustments, is worth more than one with rigid templates who passes on anything that does not look exactly like their last deal.
Sector understanding. A mezz lender who has done healthcare services or specialty contracting deals underwrites the business more accurately than a generalist. Domain knowledge reduces both diligence time and structural surprises at the closing table.
