Adjusted EBITDA: What Underwriters Add Back — And What They Don't

Where trust is won and lost

Adjusted EBITDA is the most negotiated line in any credit file. Everything downstream — DSCR, leverage multiples, covenant sizing, purchase price — flows from it. And it is the single fastest way to lose credibility with an underwriter: an add-back schedule that reads as aggressive tells committee the rest of the file will need to be re-diligenced from scratch.

Getting this right is not about maximizing the number. It is about presenting a defensible EBITDA — one where every add-back has a corresponding piece of third-party evidence, and where the reconciliation to the tax return ties to the dollar. This briefing walks through the add-backs underwriters accept, the ones they routinely reject, and how committee actually reads the quality-of-earnings schedule.

The two EBITDAs that matter

Every deal has two EBITDAs, and they are almost never the same number:

• Reported EBITDA — the number from your P&L, net income + interest + taxes + D&A. Ties cleanly to your tax return and your CPA-reviewed financials.
• Adjusted EBITDA — reported EBITDA plus a schedule of non-recurring, non-operating, or owner-related items that a third-party buyer or lender would not incur going forward.

The spread between these two numbers is the entire conversation. On a $2M reported / $2.8M adjusted file, committee is not evaluating $2.8M — they are evaluating the $800K schedule of adjustments. If that schedule holds up, the file underwrites at $2.8M. If half of it is rejected, the file underwrites at $2.4M, and the whole deal re-prices.

The add-backs underwriters accept

Five categories reliably survive quality-of-earnings scrutiny when documented:

1. Owner compensation normalization. If the owner takes $450K in W-2 salary but a market-rate replacement CEO would cost $250K, the $200K delta is a defensible add-back. Support with a comp study (industry survey, recruiter estimate, or job posting for the replacement role) and a written management transition plan.

2. Non-recurring legal and professional fees. One-time M&A due diligence, litigation that has since settled, or a specific project engagement — all addable with invoice-level detail. The test: would this cost recur under normal operations? If yes, it stays in EBITDA.

3. Related-party rent normalization. If the operating company pays $18/sqft to a real estate LLC owned by the same principal, and market rent is $12/sqft, the $6 delta is an add-back — but only with a broker opinion of value or a comparable lease as backup.

4. Discontinued product lines or customers. Revenue and cost associated with a business line that has been formally exited. Requires the exit to be completed (not "we're planning to phase out"), documented by board minutes or a written wind-down memo, and the cost trail to be traceable in the GL.

5. One-time COVID-era items. PPP forgiveness (add back the expense that was funded, not the forgiveness income), Employee Retention Credit accounting, or specific supply-chain premium costs. These are late-cycle now but still appear on 2023 comparables.

The add-backs underwriters routinely reject

Three categories almost always get rejected — and pushing them undermines the credibility of the entire schedule:

"Discretionary" owner perks that don't have a clean corporate replacement. Country club memberships, personal-use vehicles that are also used for business, family payroll where the role is genuinely part-time. If the P&L benefits from these being deductions today, the schedule cannot pretend they wouldn't recur.

"Growth investment" that is really operating cost. Marketing spend, R&D, or headcount additions labeled as "one-time growth investment" almost never come out cleanly. The test: if you removed this cost, would the top-line grow the same way next year? Almost always the answer is no — which means it is recurring OpEx.

Timing normalizations. "We under-invoiced Q3, so we're adding back the missing revenue." This is not an add-back. It is a revenue recognition question, and it belongs in the tax return reconciliation as an adjustment, not in the EBITDA schedule.

How committee reads the schedule

Underwriters do not read add-back schedules top to bottom. They scan for three signals:

1. Concentration. If two add-backs account for 80% of the delta, both must be bulletproof. The document set for those two lines needs to be exhaustive.
2. Ratio to reported. Adjusted EBITDA more than 25% above reported EBITDA is a yellow flag. More than 40% is a red flag. Not because it's necessarily wrong, but because it triggers a deeper QoE review, which costs time and often produces haircuts.
3. Third-party corroboration. Every material add-back needs a document that is not the borrower's own P&L. Invoices, comp studies, broker opinions, board minutes, executed severance agreements. Self-attestation is not evidence.

The tax-return tie-out

This is the single test that separates a defensible schedule from an indefensible one. Every add-back must reconcile to a specific line on the tax return, the general ledger, or a supporting document. If a $180K "one-time legal fee" add-back does not tie to specific invoices totaling $180K in the professional fees expense line, it will be rejected on quality-of-earnings review.

Build the reconciliation before the file goes out. QoE providers charge $40K–$90K for lower-middle-market engagements precisely because this reconciliation is time-consuming, and lenders will require it on any file above roughly $5M in debt raise.

What "defensible EBITDA" looks like

A defensible add-back schedule has three properties: every line has a corresponding document in the data room, the aggregate spread from reported EBITDA is under 25% or explicitly defended if higher, and the schedule ties dollar-for-dollar to a QoE-style reconciliation. Files with those three properties clear committee. Files without them get haircut, re-priced, or stalled in additional diligence.
