Quality of Earnings (QoE) Report: The 2026 Founder’s Guide to M&A Financial Diligence

A Quality of Earnings (QoE) report is one of the most important — and most misunderstood — documents in lower middle market M&A. For founder-owned business sellers approaching a sale, the QoE is often the difference between an offer that clears at 7x EBITDA and an offer that gets renegotiated down to 5x EBITDA after buyer diligence. This guide explains what a QoE actually is (and isn’t), who provides them, what they cost in 2026, how long they take, and — most importantly — how a sell-side QoE preempts buyer diligence to protect your deal value.

The Quality of Earnings analysis isn’t an audit (auditors give opinions on whether financial statements are presented fairly in accordance with GAAP) and isn’t a valuation (valuators apply methodologies to derive enterprise value). A QoE is a focused EBITDA validation analysis: it tests every add-back, normalizes working capital, identifies one-time items, and quantifies the “Run-Rate Adjusted EBITDA” that drives the transaction multiple. For PE buyers and sell-side M&A advisors, the QoE is the financial foundation of the deal.

CT Acquisitions runs sell-side M&A processes for founder-owned U.S. businesses ($1M-$25M EBITDA). We see firsthand how QoE quality determines deal outcomes. This guide reflects what we observe in 2026 transactions — what works, what destroys value, and how founders should approach their QoE 4-6 months before going to market.

What a Quality of Earnings (QoE) Report Actually Is

A Quality of Earnings report is an independent third-party analysis of a target company’s EBITDA designed to:

• Validate every add-back in the seller’s reported “Adjusted EBITDA” — confirming that owner compensation, personal expenses, one-time items, and related-party adjustments are legitimate and defensible.
• Identify one-time / non-recurring items that should be excluded from run-rate EBITDA: large legal settlements, COVID-era PPP forgiveness, one-time consulting expenses, gain/loss on asset sales, insurance recoveries.
• Normalize working capital — establish the “target working capital” level the business operates at, which becomes the basis for the closing working capital adjustment.
• Test revenue recognition — confirm revenue is recognized appropriately (especially important for project-based businesses, SaaS with deferred revenue, and businesses with long sales cycles).
• Quantify customer concentration — top 10 / top 20 customer analysis with revenue and gross margin by customer.
• Identify hidden liabilities — accrued PTO not on balance sheet, deferred rent, lease obligations, tax exposure.
• Produce the “Run-Rate Adjusted EBITDA” — the single number that drives the transaction multiple.

What a QoE is NOT

• Not an audit: Auditors give an opinion on whether financial statements are fairly presented in accordance with GAAP. QoE practitioners don’t.
• Not a valuation: Valuators apply methodologies (DCF, market multiples, asset approach) to derive enterprise value. QoE practitioners don’t.
• Not a comprehensive due diligence: Legal, tax, environmental, IT, HR, and operational diligence happen separately. QoE is focused specifically on the EBITDA and working-capital picture.

Sell-Side vs Buy-Side QoE: Why Sell-Side Is Modern Best Practice

Sell-Side QoE (commissioned by the seller, pre-market)

The seller engages a QoE provider 2-3 months before going to market. The QoE report is shared with prospective buyers as part of the sale process, typically alongside the Confidential Information Memorandum (CIM).

Advantages of sell-side QoE

• Preempts buyer renegotiation: Buyers can’t reduce purchase price citing “we found issues in diligence” if those issues were already disclosed in the sell-side QoE.
• Compresses transaction timeline: Buyers spend 30-50% less time on financial diligence when sell-side QoE is provided.
• Strengthens negotiating position: A clean sell-side QoE signals seller sophistication and reduces buyer pricing power.
• Identifies issues you can fix: Working capital adjustments, accrued PTO, revenue recognition issues — better to fix or normalize 6 months before sale than to absorb purchase price reductions.
• Validates add-backs proactively: Owner compensation, personal expenses, family-member salaries — all addressed before buyer scrutiny.

Buy-Side QoE (commissioned by the buyer, post-LOI)

Traditional approach: buyer signs LOI, conducts exclusive diligence over 60-90 days, commissions their own QoE provider. Result: 30-50% of LOI-stage deals get renegotiated downward (per industry surveys), often due to QoE findings.

Modern best practice: both

For $5M+ EBITDA transactions in 2026, the modern best practice is: seller commissions sell-side QoE; buyer commissions confirmatory buy-side QoE. The two QoEs typically converge within 10-15% of run-rate EBITDA. If they diverge significantly, the gap drives negotiation.

CT Acquisitions approach

In CT’s buyer-paid M&A advisory model, we facilitate sell-side QoE engagement as part of pre-market prep. The seller pays no QoE fee directly — the buyer pays the success fee at closing, which includes deal facilitation costs.

What a QoE Report Costs in 2026

QoE costs vary materially by deal size, complexity, and provider tier. 2026 ranges:

Business Size	Boutique QoE	Large Specialty	Big 4
Sub-$1M EBITDA	$10K-$15K	$15K-$25K	Rarely engaged
$1M-$3M EBITDA	$15K-$25K	$25K-$40K	$40K-$60K
$3M-$10M EBITDA	$25K-$40K	$40K-$60K	$60K-$100K
$10M-$25M EBITDA	$50K-$75K	$75K-$125K	$125K-$200K
$25M+ EBITDA	N/A	$125K-$250K	$200K-$500K+

What drives QoE cost premium

• Multi-entity structures: parent + subsidiaries + JVs typically adds 30-50% to QoE cost.
• Multi-state operations: state-level sales tax + payroll tax complexity.
• International operations: transfer pricing, multi-currency, VAT.
• Industry complexity: regulated industries (healthcare, financial services, pharma) typically 20-40% premium.
• Revenue recognition complexity: long-term contracts, percentage-of-completion accounting, deferred revenue.
• Inventory complexity: LIFO/FIFO/specific-identification, slow-moving/obsolete inventory.

Standard QoE Report Scope and Timeline

Standard scope (4-6 weeks)

A typical QoE engagement covers:

1. Engagement letter + initial document request (week 1)
2. Financial data review: 3-year historical financials + monthly TTM + tax returns (weeks 1-2)
3. Management interviews: CEO/CFO/key operational personnel (weeks 2-3)
4. Customer-level revenue analysis: top 10 / top 20 customers, revenue + gross margin (weeks 2-3)
5. Add-back validation: every line item in seller’s “Adjusted EBITDA” tested (weeks 2-4)
6. Working capital analysis: 24-36 month working capital level, normalization, target setting (weeks 3-4)
7. Revenue quality / recognition testing (weeks 3-4)
8. Draft report (week 4-5)
9. Management review + revisions (week 5-6)
10. Final report (week 6)

Standard QoE deliverables

• Executive summary: 2-3 page summary of findings.
• Run-Rate Adjusted EBITDA waterfall: reported EBITDA → normalized EBITDA → run-rate EBITDA, with every adjustment documented.
• Working capital analysis: 24-36 month trend, target working capital recommendation, peg date analysis.
• Customer concentration analysis: top 10 / top 20 customers, % of revenue, gross margin.
• Revenue quality assessment: recurring vs non-recurring revenue mix, revenue recognition methodology.
• Add-back validation tables: every add-back documented with supporting evidence.
• Hidden liabilities identified: accrued PTO, deferred rent, lease obligations, tax exposure, contingent liabilities.
• Industry / KPI benchmarking: typical, not always included.

How to maximize QoE outcomes

1. Engage 4-6 months pre-market. Gives time for findings to inform pre-sale preparation.
2. Hand over clean financials. If your books are messy, fix them BEFORE engaging QoE. QoE adjustments to clean up bookkeeping cost more than fixing the books directly.
3. Prepare detailed add-back schedule. Document every personal expense, every related-party transaction, every one-time item with supporting evidence.
4. Test working capital trends. If WC has been moving, understand why before QoE engagement.
5. Be transparent in management interviews. Hiding issues makes them worse in buy-side QoE.

How QoE Findings Affect Transaction Value

The QoE’s impact on transaction value is direct: Run-Rate Adjusted EBITDA × Multiple = Enterprise Value. Every dollar of EBITDA the QoE removes is multiplied by 5-15x and removed from your sale proceeds.

Common EBITDA reductions in QoE

• Unsupported add-backs: owner compensation in excess of market rate; personal travel; family-member salaries without legitimate work; auto expenses; club memberships. QoE removes these from reported add-backs. Typical impact: 5-15% reduction in claimed Adjusted EBITDA.
• One-time items not removed: PPP forgiveness, large insurance recoveries, gain on asset sales, one-time consulting expenses. QoE removes from run-rate. Typical impact: 5-10% of single-period EBITDA.
• Revenue recognition adjustments: deferred revenue not properly recognized, percentage-of-completion errors, channel-stuffing-like issues. Typical impact: variable, can be 10-30%+ in worst cases.
• Working capital adjustments: aggressive A/R aging, unreported A/P, inventory write-downs. Don’t directly hit EBITDA but reduce purchase price via closing WC adjustment.
• Customer concentration discounts: don’t hit EBITDA but reduce multiple. Buyers apply 1-2 turn discount for top-customer concentration above 25-30%.

Real impact example

A founder reports $2.5M EBITDA. Sell-side QoE reduces to $2.2M (-12%). At 7x multiple, the gross deal value drops from $17.5M to $15.4M — a $2.1M reduction. If the seller had discovered these issues 12-18 months pre-market, they could have addressed many of them (legitimate add-back documentation, working capital normalization, customer diversification) before sale.

How to protect deal value

• Sell-side QoE 2-3 months pre-market: Identifies issues before buyer-driven renegotiation.
• Clean books 12+ months pre-market: Reduces add-back risk.
• Customer diversification 12-18 months pre-market: Reduces concentration discount.
• Documented add-back schedule: Maintained quarterly with supporting evidence.
• Engage a sell-side M&A advisor 18-24 months pre-process: CT Acquisitions provides this evaluation at no cost in our buyer-paid model.

FAQ: Quality of Earnings

What is a Quality of Earnings report?

A Quality of Earnings (QoE) report is an independent third-party analysis of a target company’s EBITDA: validates add-backs, identifies one-time items, normalizes working capital, confirms Run-Rate Adjusted EBITDA. Not an audit, not a valuation — a focused EBITDA validation analysis.

Is a Quality of Earnings an audit?

No. Audits give opinions on whether financial statements are fairly presented in accordance with GAAP. QoE analyses don’t opine on GAAP compliance — they focus specifically on EBITDA quality and run-rate adjustment.

How long does a Quality of Earnings report take?

Standard timeline: 4-6 weeks from engagement to draft report. Add 1-2 weeks for management review and revisions. Complex multi-entity or regulated-industry transactions can take 8-10 weeks.

How much does a QoE report cost in 2026?

By business size: sub-$1M EBITDA $10K-$25K; $1M-$3M EBITDA $15K-$40K; $3M-$10M EBITDA $25K-$100K; $10M-$25M EBITDA $50K-$200K; $25M+ EBITDA $125K-$500K+. Multi-entity, multi-state, international, or regulated industry adds 30-50%.

Who are the top QoE providers?

Big 4: PwC, KPMG, Deloitte, EY (highest cost, biggest brand). Large specialty: BDO, Grant Thornton, Baker Tilly, RSM, CohnReznick (sweet spot for $5M-$25M EBITDA). Boutique: Aprio, Cherry Bekaert, FORVIS, Eide Bailly, Marcum, Mazars, Plante Moran, Citrin Cooperman (best for $1M-$10M EBITDA).

What’s the difference between sell-side and buy-side QoE?

Sell-side QoE is commissioned by the seller 2-3 months pre-market. Buy-side QoE is commissioned by the buyer post-LOI. Modern best practice: seller provides sell-side QoE to preempt buyer renegotiation; buyer commissions confirmatory buy-side QoE in exclusive diligence.

Is Quality of Earnings the same as Adjusted EBITDA?

No. Adjusted EBITDA is a calculation: reported EBITDA + add-backs. The QoE analysis validates whether the Adjusted EBITDA calculation is defensible. Output of QoE: Run-Rate Adjusted EBITDA, often lower than seller’s claimed Adjusted EBITDA.

What is Run-Rate Adjusted EBITDA?

The forward-looking EBITDA the business is expected to generate post-close, after removing one-time items and normalizing add-backs. This is the number that drives the transaction multiple. Run-Rate Adjusted EBITDA × Multiple = Enterprise Value.

When should I engage a QoE provider?

For sell-side QoE: 4-6 months before going to market. This allows time for findings to inform pre-sale preparation (add-back documentation, working capital normalization, customer diversification). For buy-side QoE: immediately after signing LOI, before exclusive diligence begins.

How does QoE affect deal value?

Direct multiplicative impact. Every dollar QoE removes from EBITDA is multiplied by 5-15x and removed from sale proceeds. Typical: 5-15% reduction in claimed Adjusted EBITDA from QoE adjustments = $1-3M+ reduction in deal value on a $2M EBITDA business at 7x multiple.

What does CT Acquisitions do for QoE?

In our buyer-paid M&A advisory model, CT facilitates sell-side QoE engagement as part of pre-market prep. We connect the seller to appropriate QoE providers (Big 4 / large specialty / boutique based on deal size), help prepare the add-back schedule and document request response, and coordinate with the eventual buyer’s buy-side QoE. The seller pays no QoE fee directly — the buyer pays the success fee at closing.
