What buyers assume: “We’re profitable and the bank likes us. We can buy something meaningful. Let’s look at targets our own size.”

What the constraints say: a $3M-EBITDA company can absolutely acquire, but the ceiling on a first bolt-on is set by three things that have nothing to do with ambition, how much senior debt the combined entity supports, how much equity or gap capital you can put up alongside it, and how much integration your team can survive without breaking the business you already have.

Start with the leverage the combined entity supports

A senior lender sizes a deal off pro forma EBITDA, the combined earnings of buyer and target, adjusted for defensible synergies. For a healthy lower-middle-market company, senior leverage commonly lands somewhere around 2.5–3.5× EBITDA, depending on industry, asset base, and recurring revenue. It’s a range, not a promise, and asset-light service businesses sit at the low end.

So a $3M-EBITDA buyer acquiring a $1M-EBITDA target creates a ~$4M pro forma entity. At 3×, that supports roughly $12M of senior debt, but you’re not starting from zero. Net that against debt already on the buyer’s balance sheet, and the incremental senior capacity for the deal is what’s left. This is the single number that most reshapes the buy-box, and it’s why first-time acquirers who model off total capacity overshoot.

Now stack the rest of the purchase price

Senior debt rarely funds the whole price. A realistic capital stack for a bolt-on:

  • Senior debt, the largest layer, sized as above, cheapest cost of capital, slowest to fund.
  • Seller financing, a note the seller carries, typically 10–30% of price. Every dollar here is a dollar you don’t raise this month, and a seller’s willingness to carry paper is itself a signal about the numbers.
  • Buyer equity / cash, your own money, the layer that determines how much control and upside you keep.
  • Gap / bridge capital, short-term capital that funds deposits, escrows, and the close itself in the weeks before senior funds. Revenue-based financing on the acquirer is a common tool here because it doesn’t touch the target’s collateral, which the senior lender is about to lien.

A $1M-EBITDA target at 5× is a $5M deal. It might pencil as ~$3M senior + ~$1M seller note + ~$1M buyer equity, with a short bridge covering the timing gap between close and senior draw. Change any one layer and the achievable target size moves.

The buy-box that actually results

Put the constraints together and the realistic first bolt-on for a $3M-EBITDA acquirer is usually a target in the $500K–$1.5M EBITDA range, big enough to move the needle and earn re-rating credit, small enough that a single deal’s failure doesn’t sink the platform. What makes a target inside the box, beyond size:

  • It reduces your risk, not just adds revenue. A bolt-on that diversifies customer concentration, adds a recurring revenue line, or brings management depth earns multiple expansion. One that just adds more of the same fragile earnings does not. (See “Why Serial Acquirers Command a Higher Multiple”.)
  • Its books are diligenceable. A target whose earnings survive a quality-of-earnings review is fundable. One that runs on the owner’s memory and a shoebox will get haircut hard, if a lender will touch it at all.
  • It’s geographically or operationally absorbable. Integration debt, the systems, the culture, the second location, the redundant back office, is the cost line first-time acquirers never model, and it’s paid in management attention you can’t buy back.

What’s out of the box (for now)

A transformational, same-size merger. Anything requiring senior leverage well past what the combined cash flow covers. A target with concentration or earnings-quality problems worse than your own. And any deal your team has to run while onboarding the last one, the second acquisition is the dangerous one precisely because leverage and integration load stack faster than management bandwidth does.
