Strategic EBITDA Optimization Ahead of a Sale or Equity Raise

A buyer doesn't pay a multiple of the number on your accountant's income statement. They pay a multiple of adjusted EBITDA, a figure that starts with reported earnings and then gets rebuilt to reflect what the business would actually earn under normal ownership, without the specific quirks of how the current owner happened to run it. That rebuilding process, and how defensible it is under diligence, often moves the final sale price more than the underlying operating performance does.

What A Multiple Is Actually Applied To

Middle market EBITDA multiples have held up better than headline economic uncertainty might suggest. Average M&A valuations across the middle market settled at 9.8x EV to EBITDA in 2025, up from 9.4x in 2024 and 9.0x in 2023, even as the year included real disruption from tariff-driven uncertainty (Capstone Partners, 2026). GF Data's private equity-sponsored transaction data, covering deals between $10 million and $500 million in enterprise value, put the 2025 middle market average closer to 7.2 to 7.5x EBITDA (Praxis Rock, 2026). The gap between those two figures is itself informative: value-weighted averages skew toward larger transactions, while count-based averages better reflect what a typical mid-sized private company actually sells for.

The Legitimate Add-Backs

Common, defensible EBITDA adjustments include owner compensation above a fair market rate, replacing it with what a professional, arm's length manager would actually cost; one-time expenses like litigation settlements, relocation costs, or non-recurring consulting fees; personal expenses run through the business, vehicles, travel, or a family member's salary for a role they don't actively perform; below-market rent paid on real estate the owner holds personally; and genuinely non-recurring revenue or cost items (Praxis Rock, 2026). These adjustments, commonly called add-backs, are where the real negotiation in a sale process happens, far more than in the headline revenue or gross margin figures.

What A Buyer's Diligence Team Strips Back Out

Every add-back a seller proposes gets tested during buy-side diligence, and unsupported ones get removed, which directly reduces the adjusted EBITDA a buyer is willing to pay a multiple on. This is precisely the value an independent sell-side quality of earnings report provides. It validates the adjustments before a buyer's team ever sees them, using an independent accounting firm rather than the seller's own assertions, which is exactly why GF Data's analysis found sellers who used one achieving meaningfully higher realized multiples, with the effect most pronounced in deals above $50 million where the diligence process is more rigorous by default (Middle Market Growth, 2025). Smaller deals in the same dataset didn't show the same lift, likely because diligence at that size is inherently less exhaustive either way.

Why Timing Matters

Advisors interviewed on the GF Data findings consistently point to the same window: beginning a sell-side quality of earnings engagement three to six months ahead of going to market gives a company time to actually fix what the report finds, not just document it (Middle Market Growth, 2025). An owner who commissions the report the week before launching a sale process is stuck disclosing whatever it finds. An owner who commissions it six months earlier has time to clean up the underlying issue, tighten a customer contract, formalize an informal related-party arrangement, before a single prospective buyer ever sees the numbers.

SDE vs. EBITDA: The Transition Point

Very small businesses, generally those under roughly $1 million in EBITDA, are typically valued on seller's discretionary earnings rather than EBITDA. SDE adds back the owner's full compensation, benefits and perquisites, reflecting the total economic benefit available to a single full-time owner-operator, and typically trades at multiples of 1.5x to 4x rather than the higher multiples applied to EBITDA-based valuations (Sofer Advisors, 2026). The transition from SDE to EBITDA generally happens around the $2 million EBITDA mark, once a business has grown large enough that a professional management layer could realistically replace the owner's day-to-day operating role. Applying the wrong framework, EBITDA multiples on an SDE-scale business or vice versa, produces a valuation that can be off by 20 to 40% in either direction (Sofer Advisors, 2026).

A Checklist

1. Start a sell-side quality of earnings process three to six months before going to market, giving time to fix issues rather than just disclose them.
2. Document every proposed add-back with a clear paper trail, invoices, contracts, and comparable market data, before a buyer's diligence team asks for it.
3. Separate personal and business expenses cleanly well before a sale process begins, since untangling them under time pressure looks worse to a buyer than if they'd never been mixed at all.
4. Confirm whether your business should be valued on SDE or EBITDA before assuming a published industry multiple applies directly to your numbers.
5. Get an independent, credible valuation range before entering negotiations, so you know whether an offer is fair before a buyer's advisor is the only one who's done the math.
