EBITDA Adjustments in 2026: The Real List, the Worked Example, and the Lines Buyers Reject

By chrisomo

EBITDA adjustments are the add-backs and subtractions a buyer applies to a target company’s reported EBITDA to arrive at the recurring, defensible cash-earning power that prices the deal. In 2026, the working list runs 14 categories, but only a handful survive buyer pushback intact. The difference between a $4.25M reported EBITDA and a $4.89M Adjusted EBITDA is not accounting trivia; at an 8x multiple, that gap is worth $5.1M of purchase price.

What are EBITDA adjustments?

EBITDA adjustments are line-item modifications to a target company’s reported earnings before interest, taxes, depreciation, and amortization, designed to convert that figure into a measure of recurring, normalized profitability that a buyer can underwrite. The mechanics live in the Quality of Earnings report and the workpapers behind it. Each adjustment is either an add-back (which increases EBITDA) or a deduction (which decreases EBITDA), supported by source documentation: invoices, board minutes, lease comparables, contract amendments. EBITDA is a non-GAAP measure; SEC Regulation G governs its disclosure in public filings, but in private M&A the adjustments are governed by the purchase agreement’s definition of Adjusted EBITDA. Source: SEC Regulation G, 17 CFR § 244.100.

Why EBITDA adjustments matter in M&A deals

Adjusted EBITDA is the denominator of the deal multiple. A target with $4M reported EBITDA selling at 8x produces $32M of enterprise value. The same target with $4.5M Adjusted EBITDA at the same multiple produces $36M. The $4M of additional purchase price is the entire economic motivation for the adjustment exercise. Buyers fund senior debt against Adjusted EBITDA, lenders set credit-agreement covenants against Adjusted EBITDA, and earn-out triggers fire against Adjusted EBITDA. The 2025 SRS Acquiom Buy-Side Representations & Warranties Insurance Claims Study found that 18 percent of post-closing M&A disputes trace to disagreements over EBITDA adjustment definitions in the purchase agreement. The work happens during diligence as part of the quality of earnings report process, but the contractual stakes extend years past closing. Sellers planning ahead for a sale should review the M&A playbook 12 to 24 months before launch to clean up the financial categories that drive the largest add-back disputes.

What are the 14 EBITDA adjustment categories that show up in 2026 QoE reports?

1. Owner compensation excess. Founder-CEOs in privately held businesses typically draw a salary plus bonus that exceeds the cost of replacing the role with a market-rate hire. The add-back is the delta between actual compensation and a benchmarked market salary plus bonus, sourced from BLS Occupational Employment Statistics, Robert Half salary guides, or an industry-specific compensation study. Buyer pushback: limited, when the benchmark is sourced from a recognized survey. Survives almost universally.

2. Related-party rent normalization. A target leasing its facility from a real estate LLC owned by the seller often pays above- or below-market rent. The adjustment normalizes to a third-party comparable using CoStar, LoopNet, or a local broker opinion. Buyer pushback: minimal when the comparable is documented. Critical when the seller plans to retain the real estate post-closing and lease to the buyer.

3. Discretionary owner perks. Personal use of company vehicles, country club memberships, owner family member salaries for nominal work, personal travel expensed through the business. These survive as add-backs when itemized with credit-card statements and expense reports. Buyer pushback: moderate, focused on documentation. The IRS rules under IRC § 274 already disallow some of these for tax purposes, which provides a paper trail.

4. One-time legal fees. Litigation that has been settled and dismissed with prejudice, M&A advisory fees, restructuring legal fees, and one-off SEC or regulatory inquiries. The add-back requires legal-counsel confirmation that the matter is closed. Buyer pushback: heavy on the substantiation that the matter will not recur. Ongoing employment litigation generally fails the test.

5. COVID PPP forgiveness reversal. Paycheck Protection Program loan forgiveness was recorded as other income for many private companies in 2020 and 2021, inflating that year’s EBITDA. Trailing-twelve-month EBITDA calculations that include the PPP forgiveness must subtract it. By 2026 this is a tail issue affecting only multi-year EBITDA averages, but it still appears in roll-ups using 3-year EBITDA. Buyer pushback: none, this is a clear subtraction.

6. Restructuring charges. Severance from a one-time reduction in force, lease termination costs from a facility closure, write-offs of abandoned IT projects. The add-back requires board minutes documenting the restructuring decision and a credible argument that the underlying issue is resolved. Buyer pushback: heavy when the company has restructured multiple times in 3 years (the pattern suggests recurring, not one-time).

7. Non-recurring revenue. A one-time customer windfall, insurance recovery treated as revenue, government grant income, or a one-off project that will not repeat. The adjustment is a subtraction from EBITDA. Buyer pushback: this is the category buyers police most aggressively, because sellers frequently classify recurring revenue as non-recurring to inflate forward run-rate. Per the 2024 SRS Acquiom study, 31 percent of seller-proposed non-recurring revenue add-backs are reversed during diligence.

8. Stock-based compensation. The add-back treats SBC as a non-cash expense, restoring it to EBITDA. Buyer pushback: heavy. The SEC, FASB, and most institutional lenders treat SBC as a real economic cost. Buyers underwriting against an Adjusted EBITDA that adds back SBC typically reduce the multiple by 0.5 to 1.0 turns to compensate. In 2026 sponsor practice, SBC is almost always retained as an expense in the buyer’s underwriting model regardless of the seller’s QoE treatment.

9. Pension or retirement plan true-ups. A one-time catch-up contribution to a defined-benefit pension plan, or a one-off 401(k) profit-sharing contribution above the historical rate. The add-back is the excess over the normalized contribution level. Buyer pushback: heavy when the plan is underfunded, because the underfunding becomes a debt-like item that reduces purchase price separately.

10. Inventory write-downs above normal. A specific obsolescence write-down or a one-time inventory loss from a discontinued product line. The add-back requires SKU-level documentation. Buyer pushback: moderate, focused on whether the write-down pattern is truly non-recurring or reflects underlying inventory management failures.

11. Insurance proceeds for losses already recognized. Business interruption insurance recoveries received in a different period than the loss they offset. The treatment depends on whether the original loss was added back. If both the loss and the recovery are non-recurring, both come out of EBITDA; the net should approximate zero. Buyer pushback: heavy when only the proceeds are shown, not the underlying loss.

12. Bad debt expense above normalized level. A specific customer write-off above the company’s historical bad-debt rate. The add-back is the excess over the 3-year average bad-debt expense as a percentage of revenue. Buyer pushback: moderate when the named customer is documented as bankrupt or out of business. Heavy when the seller cannot produce a customer-specific reason.

13. Goodwill impairment. A non-cash write-down of goodwill from a prior acquisition. The add-back is straightforward because the charge is non-cash. Buyer pushback: minimal on the add-back itself, but the underlying impairment signals that a prior acquisition underperformed, which prompts deeper diligence into the integration history.

14. Foreign exchange gains or losses. Unrealized translation gains and losses on foreign subsidiary balances under ASC 830. The standard treatment is to remove both gains and losses from Adjusted EBITDA because they are non-cash and non-recurring relative to operating activity. Buyer pushback: low on the principle, moderate on the specific calculation when the company has material foreign operations.

Worked example: ABC Manufacturing Co.

ABC Manufacturing Co. is a hypothetical industrial parts distributor with $42M revenue, $4,250,000 reported EBITDA, and a sole shareholder who founded the business 22 years ago. The buyer is a lower-middle-market private equity sponsor commissioning a buy-side QoE through RSM US. The trailing-twelve-month period ends December 31, 2025. The adjustment schedule runs as follows.

At a market multiple of 8.0x for a $4.9M EBITDA industrial distribution business in 2026, per GF Data middle-market multiples benchmarks, the Adjusted EBITDA generates $39.1M of enterprise value. The same multiple applied to reported EBITDA generates $34.0M. The adjustment exercise creates $5.1M of incremental purchase price, of which roughly $4.5M flows to the seller after transaction costs.

EBITDA vs Adjusted EBITDA vs Pro Forma EBITDA: how they differ

The distinction is not academic. A purchase agreement that defines Adjusted EBITDA as “EBITDA as reported on the QoE Report dated [X]” sets a clear contractual reference. A purchase agreement that defines Adjusted EBITDA as “EBITDA adjusted for non-recurring items reasonably determined by Buyer” creates years of post-closing dispute potential. Credit agreements similarly distinguish: senior debt covenants generally measure against Adjusted EBITDA defined to include limited add-backs and exclude pro forma synergies, while subordinated debt agreements may permit broader add-back baskets.

Recent changes and market context 2025 to 2026

The biggest change in 2025-2026 EBITDA adjustment practice is buyer aggression on the management-bonus and SBC add-backs. The 2025 Federal Reserve Senior Loan Officer Survey reported senior debt covenants tightening through 2025 as the credit cycle matured, which forced sponsors to underwrite tighter Adjusted EBITDA definitions. Sponsor LOIs in the lower middle market in 2026 routinely exclude all stock-based compensation add-backs, where in 2021 SBC add-backs were standard. The market has moved to a more conservative posture.

A second shift: the rise of “synergy add-backs with realization periods.” Sponsor purchase agreements increasingly permit pro forma synergies in covenant calculations only if they are realized within 18 months of closing, with documentation reviewed by an independent accounting firm. This brings discipline to a category that was previously a hand-wave. The practical effect is that synergy add-backs above $250K require a documented integration plan.

A third shift, particularly visible in industrial roll-ups: customer-specific gross margin adjustments. Where the target sells to a single dominant customer at a margin meaningfully different from the rest of the book, buyers now demand a customer-level gross margin walk in the QoE rather than accepting blended numbers. This change reflects the maturity of QoE analytics tooling like DataSnipper, Alteryx, and MindBridge, which make customer-level granularity feasible at the same fee level.

Common pitfalls

• Treating SBC as a free add-back. In 2026, stock-based compensation is the single most heavily scrutinized add-back. Sellers that propose SBC add-backs should expect buyers to either reject them outright or reduce the multiple by 0.5 to 1.0 turns in compensation.
• Classifying recurring revenue as non-recurring. Customers labeled “one-time project” who reorder the following quarter are the most common reason QoE reports get reworked. Verify reorder patterns over a 24-month window before claiming non-recurring revenue.
• Missing the related-party rent in a sale-leaseback. When the seller retains the real estate and leases to the buyer post-closing, the going-forward rent affects post-closing EBITDA. Failing to model the post-closing rent at market creates a covenant-default risk in year one.
• Adding back legal fees for ongoing litigation. Litigation that is settled and dismissed with prejudice qualifies. Litigation in progress, including matters where settlement is “imminent,” does not. Sellers routinely lose this fight.
• Forgetting the working-capital implications. A bad-debt expense add-back must be paired with an analysis of whether the underlying customer receivables remain on the balance sheet and will affect the working-capital peg. Adjusting EBITDA without adjusting working capital is half a job.
• Using the wrong benchmark for owner compensation. Generic BLS data understates compensation for industry-specific CEO roles. Use industry compensation surveys from sources like Robert Half, ExecuComp, or NACD when defensible.
• Skipping the documentation step. Every add-back needs a workpaper. “Management estimate” is not documentation. If the seller cannot produce the invoice, contract, or board resolution, the add-back will not survive buyer review.

Frequently asked questions

What is the difference between an add-back and a normalizing adjustment?

The terms are used interchangeably in QoE practice. Both refer to modifications applied to reported EBITDA to derive Adjusted EBITDA. Some practitioners reserve “add-back” for owner-specific items (compensation, perks, related-party rent) and “normalizing adjustment” for non-recurring items (one-time legal fees, restructuring, write-downs), but the distinction is stylistic, not technical.

How much do EBITDA adjustments typically increase reported EBITDA?

In the 2024 SRS Acquiom Middle-Market Deal Terms Study covering 1,150 deals, the median net adjustment was 12 percent of reported EBITDA. The 75th percentile was 22 percent. Founder-led businesses with significant discretionary owner perks frequently land in the 15 to 25 percent range. Professionally managed businesses with audited financials more often land in the 3 to 8 percent range.

Can buyers add their own adjustments that reduce EBITDA?

Yes. Buy-side QoE practitioners routinely identify negative adjustments: revenue recognized prematurely under ASC 606, capitalized expenses that should be expensed, related-party transactions priced favorably to the target, and missing accruals for warranty or product-return reserves. The net adjustment can be negative when the seller’s accounting is aggressive.

What is a “quality” adjustment versus a “non-recurring” adjustment?

A quality adjustment fixes the way revenue or expense was recorded; for example, correcting an error in revenue recognition timing under ASC 606. A non-recurring adjustment removes an item that happened but will not happen again; for example, a one-time legal settlement. Both are normalizing adjustments, but they have different supporting documentation requirements.

Does adding back SBC require buyer agreement in the purchase agreement?

Yes. The purchase agreement’s Adjusted EBITDA definition controls. If the agreement excludes SBC from the add-back list, the seller cannot unilaterally include it in earn-out calculations or covenant tests. Sellers negotiating SBC into the definition should expect counterparty pushback and possible multiple reduction in 2026.

How are EBITDA adjustments treated in covenant calculations after closing?

The credit agreement defines its own Adjusted EBITDA, which is typically narrower than the purchase-agreement definition. Lenders permit specific add-back categories with caps: management fees, board-approved restructuring charges (with realization-period limits), and a limited synergy basket usually capped at 20 to 25 percent of unadjusted EBITDA. Add-backs accepted at signing must continue to qualify under the credit agreement’s specific definitions, which can differ.

What documentation do I need to support EBITDA adjustments?

Source documents win arguments. Owner compensation add-backs need W-2 forms and a benchmarked salary survey. Related-party rent needs the lease agreement plus a third-party comparable. One-time legal fees need invoices and a counsel letter confirming the matter is closed. Restructuring needs board minutes. Customer windfall non-recurring revenue needs the customer contract and a documented reorder pattern.

What is the cost of preparing the EBITDA adjustment schedule?

The adjustment schedule is the central deliverable of the QoE report. For a $5M EBITDA target, the full QoE engagement runs $35,000 to $75,000 in 2026. The adjustment-schedule work itself is roughly half the fee, with the other half covering working-capital, debt-like items, and customer concentration analysis. See our separate guide on quality of earnings report cost structure for the full fee breakdown, or our learn library for the underlying accounting concepts.

What happens to EBITDA adjustments in an earn-out calculation?

Earn-out provisions reference a specific definition of Adjusted EBITDA, usually frozen to the methodology in the closing QoE report. Buyer post-closing accounting changes that would inflate or deflate the calculation are typically prohibited by the agreement. Disputes are resolved through an independent accounting firm referee, often Big 4 alumni at firms like Ankura, FTI Consulting, or Berkeley Research Group, with binding determinations.
