Structuring Senior Debt for Lower Middle Market Buyouts

Leverage levels, covenant packages, and unitranche versus split-lien: what private equity sponsors should expect when financing a platform acquisition.

Leverage Expectations in the $1M to $10M EBITDA Band

Lower middle market leverage is a function of business quality, not just size. A services platform with recurring contracts, low customer concentration, and stable margins might support 3.5x to 4.0x total leverage. A cyclical manufacturer with two customers representing 60% of revenue will be lucky to see 2.5x, regardless of how strong last year looked.

Sponsors should build the capital stack backwards from free cash flow. If the target produces $4 million of EBITDA with $600,000 of maintenance capital expenditure and a normalized cash tax burden, the actual cash available for debt service is materially lower than the headline number, and that is what the lender will size against.

The practical implication is that the equity check is usually 40% to 55% of total capitalization in this market. Sponsors who anchor on the 70% leverage they saw in a 2021 deal will lose auctions to buyers whose financing assumptions are current.

Unitranche Versus a Split Senior and Sub Structure

A unitranche facility blends what would traditionally be senior and subordinated debt into a single tranche with one credit agreement, one blended rate, and one lender relationship. For a lower middle market platform, that simplicity is worth real money in legal fees, closing speed, and avoiding intercreditor negotiations while the LOI clock runs.

A split structure of a bank senior facility plus a mezzanine or subordinated note can produce a lower blended cost when the senior piece prices tightly. The tradeoff is complexity: two credit agreements, an intercreditor agreement, and two lenders who must both approve add-on acquisitions and amendments.

The right answer depends on your acquisition strategy. If the platform will complete three add-ons in eighteen months, the ability to get an amendment approved quickly is worth more than 50 basis points of blended pricing. Angel Funding Group arranges both structures and models the total cost of capital across the projected hold, not just at close.

Covenants, Cures, and Room to Operate

Expect a covenant package built around total leverage, fixed charge coverage, and often a minimum liquidity test. The levels matter less than the cushion: a leverage covenant set at 4.25x when you close at 3.75x gives you a 12% EBITDA decline before a technical default, which is thin for a business with any cyclicality.

Negotiate an equity cure right with reasonable mechanics. Two cures in any four-quarter period and four over the life of the facility is a common landing point, and getting the cure treated as an EBITDA add-back rather than a debt paydown gives the sponsor meaningfully more flexibility.

Pay equal attention to the definition of EBITDA itself. Permitted add-backs for one-time integration costs, transaction expenses, and run-rate synergies from completed add-ons can move your covenant math by a full turn. That negotiation happens in the credit agreement, not the term sheet, so involve counsel early.

Speed, Certainty, and Winning the Auction

In a competitive process, financing certainty is often worth more than an extra half turn of price. Sellers and bankers discount bids from buyers whose debt is uncommitted, and a sponsor who can attach a credible lender support letter to the LOI moves to the top of the second round.

That requires a lender who will engage from a confidential information memorandum and a preliminary model rather than waiting for full quality of earnings. Angel Funding Group routinely provides soft commitments within days of reviewing the CIM so sponsors can bid with confidence.

Independent and fundless sponsors face an additional hurdle: proving the equity is real. Lining up a committed equity partner or a written indication from your capital source before approaching debt providers materially improves the terms you will be offered, because it removes the biggest execution question from the lender’s mind.

Building the Facility for What Comes Next

The platform loan should anticipate the add-on strategy. Negotiate a committed or best-efforts delayed draw term loan at close, sized to your near-term pipeline, and define the acquisition basket clearly: dollar caps, pro forma leverage tests, and whether lender consent is required below a threshold.

Include a revolving facility for working capital even if the business does not need it on day one. Add-ons consume cash in the first ninety days through integration costs and receivable timing, and drawing on a pre-negotiated revolver is far cheaper than amending the term loan.

Finally, think about the exit. Prepayment structures, portability provisions, and change-of-control language all affect what happens when you sell in year four. A facility that is portable to a qualified buyer can be a genuine value driver in the sale process.
