In the mid-market, the “how” of a purchase is often more significant than the “how much.” A sophisticated buyer does not simply write a check; they engineer a Capital Stack—a layered structure of equity, seniority, and risk that determines the internal rate of return (IRR) and the operational safety net of the company post-acquisition.
At David Mayfair, we advise against the “max-leverage” approach often seen in smaller brokerages. In the 2026 economic landscape, the goal is not to see how much debt a business can carry, but how much debt it can service while still funding its own growth.
The Anatomy of the Stack
A well-constructed capital stack is a pyramid of risk and cost. As you move from the base to the apex, the cost of capital increases, but the security required decreases.
-
Senior Debt (The Foundation): Typically provided by commercial banks, this is the least expensive capital (Base Rate + 2-4%). It is secured by the company’s assets (Accounts Receivable, Inventory, Equipment). Sophisticated buyers aim for a Senior Debt-to-EBITDA ratio of 2x to 3x, ensuring the “Debt Service Coverage Ratio” remains healthy even during a market dip.
-
Mezzanine / Subordinated Debt (The Bridge): This sits between senior debt and equity. It is “patient capital”—often interest-only with a “balloon” payment at the end. It is more expensive (10-15%) but requires no collateral, allowing the buyer to bridge the gap between the bank’s comfort zone and the purchase price without diluting their own equity.
-
Seller Carry / Vendor Note (The Alignment): Perhaps the most critical component for a David Mayfair acquisition. By asking the seller to “carry” 10–20% of the purchase price as a secondary note, you achieve two things: you lower your upfront cash requirement, and you keep the seller “tethered” to the transition. If the business fails to perform as represented, the seller note is your primary point of recourse.
-
Equity (The Tip): This is your skin in the game. In a sophisticated deal, equity should represent 20–30% of the total stack. This provides enough “cushion” to satisfy senior lenders while maximizing the “leverage effect” on your final returns.
The Cost of “Over-Leveraging”
Many buyers fall into the trap of using too much debt to achieve a higher headline price. This creates “Breakeven Anxiety.” If a company’s EBITDA is $2M and its debt service is $1.5M, there is no margin for error. One bad quarter or one lost contract can trigger a “Covenant Breach,” giving the bank the right to seize control of the asset.
We advocate for Covenant-Light structures or “Headroom” planning. We ensure that even after the debt is paid, the business retains enough “Free Cash Flow” to reinvest in the very systems and talent that justified the acquisition in the first place.
The “Step-Down” Strategy
A sophisticated capital stack is dynamic. We look for “Refinancing Triggers”—points 18 to 24 months post-close where the improved performance of the business allows the buyer to replace expensive Mezzanine debt with cheaper Senior Debt. This “Recapitalization” is often the moment where the buyer’s initial equity investment is fully de-risked.
At David Mayfair, we don’t just find the target; we build the engine that pays for it. A deal is only as strong as the architecture that supports it.
