Quality of Earnings Report: What It Covers, What It Costs, and When You Need One

A quality of earnings report (QoE) is an independent, transaction-specific analysis that answers one question a buyer cannot afford to get wrong: is the EBITDA you are pricing off real, recurring, and sustainable? It takes the earnings a seller reports, strips out what is one-off, owner-related, mis-timed, or dressed up, and rebuilds them into a number that should still hold at completion and beyond. Done well, it is not a box to tick before a deal closes — it is the analysis that tells you whether the deal makes sense at all.

This matters because most acquisitions disappoint. Research summarized by Acquisition Stars — drawing on long-running findings from Harvard Business Review and KPMG — puts the share of M&A deals that fail to create shareholder value at 70–90%. The same summary attributes roughly 31% of M&A failures to due-diligence shortcomings and 42% to overpayment: two failure modes a rigorous QoE exists specifically to prevent. The report does not guarantee a good outcome. But going in without one means pricing a business on numbers no independent party has tested.

What a Quality of Earnings Report Is — and What It Is Not

A QoE is a forward-looking read on earnings quality, prepared for a named transaction and a named decision-maker. It is granular, often working month-by-month rather than year-by-year, and it is written to be argued in an investment or credit committee. It is explicitly not an audit, not a valuation, and not a guarantee. It will not certify financial statements, it will not opine on whether the price is fair, and it cannot find fraud that the underlying records were engineered to hide. What it does do is tell you how much confidence the earnings number deserves — and where the soft spots are.

• It is an independent test of whether reported earnings are sustainable and repeatable.
• It is a negotiation and structuring tool — findings feed price, the working-capital peg, and indemnities.
• It is not an audit or a statutory assurance opinion.
• It is not a valuation or a fairness opinion.
• It is not a clean bill of health — a QoE surfaces risk; it does not eliminate it.

Quality of Earnings vs Audit: Why One Cannot Replace the Other

The most common — and most expensive — misconception is that a recent audit makes a quality of earnings report redundant. It does not. An audit asks whether historical statements are materially correct against an accounting framework, for the benefit of shareholders and regulators. A QoE asks whether this buyer should rely on this earnings number for this deal. The audiences differ, the materiality thresholds differ, and the questions differ. An audited number can be entirely accurate under GAAP and still be a poor basis for a price, because it includes one-off gains, owner perks, and revenue that will not recur once the founder leaves.

Inside the Report: The EBITDA Bridge From Reported to Sustainable

The analytical heart of any QoE is the EBITDA bridge — the walk from the earnings in management reports to the earnings a buyer can actually underwrite. Each step is an adjustment, and each adjustment is where money is made or lost. On a deal priced at a 10x multiple, a defensible $100,000 reduction in adjusted EBITDA moves the price by $1,000,000, so the discipline applied to add-backs is not academic — it is the negotiation. The categories are consistent across most engagements.

1. 01Reported EBITDA — the starting point from the management accounts.
2. 02Non-recurring items — one-off legal costs, restructuring, COVID-era distortions, insurance recoveries.
3. 03Owner and related-party adjustments — above-market salaries, personal expenses, related-party rent normalized to market.
4. 04Accounting-policy and cut-off corrections — revenue recognized too early, expenses capitalized that should be expensed, timing breaks.
5. 05Pro forma and run-rate items — full-year effect of price changes, lost or won contracts, headcount already actioned.
6. 06Sustainable / adjusted EBITDA — the defensible number that should survive to completion.

The hard part is judgment, not arithmetic. A management team has every incentive to present a generous, run-rate-flattered number; the job of diligence is to separate genuine, defensible adjustments from inflated ones. We go deeper on exactly where that line sits in how diligence separates real add-backs from inflated ones, because a single aggressive add-back, left unchallenged, can quietly reset an entire valuation.

Beyond Earnings: Net Debt, Working Capital, and Cash Conversion

Earnings get the attention, but the items that quietly move equity value sit one layer down. Two deals at the same EBITDA and the same multiple can transfer very different amounts of equity once net debt and a working-capital target are settled. A QoE defines net debt — including the debt-like items sellers rarely volunteer, such as deferred consideration, unfunded pensions, overdue payables, and accrued bonuses — and sets a normalized working-capital peg that holds at completion. Get the peg wrong and the buyer funds the seller's working capital twice.

Cash conversion is the final check. Profit is an opinion; cash is a fact. A business reporting healthy EBITDA that converts poorly to cash — because receivables are stretched, capex is understated, or earnings are seasonal — is a different risk than its income statement suggests, and a lender lives or dies by that distinction. Strong diligence traces the cash, models intra-year funding need, and tests covenant headroom before anyone commits. With the US addressable market for private credit estimated at over $30 trillion (McKinsey, 2025), the population of lenders who need this exact analysis before funding is only growing.

Buy-Side vs Sell-Side QoE: Who Commissions It and Why Independence Matters

A buy-side quality of earnings is commissioned by the acquirer or lender — the party putting capital at risk — and its loyalty is to that party alone. A sell-side QoE is commissioned by the seller before going to market, to find and fix problems on their own terms and to give buyers a credible starting point. Both are legitimate; they answer to different masters. The non-negotiable in either case is independence from the party whose money is on the line. A report prepared by someone aligned with the seller's price is marketing, not diligence.

Sell-side QoE has moved from edge case to norm. GF Data, analyzing 360 transactions completed since Q3 2024, found that around 50% of founder-led lower-middle-market businesses now commission a sell-side QoE — and that deals carrying one traded at an average 7.4x TEV/EBITDA versus 7.0x without, with the uplift concentrated above $50 million in enterprise value. Adoption runs even higher among sponsor-backed sellers: the same report cites an industry estimate that at least 90% of PE-backed deals now use one. Sellers who skip it are increasingly the exception, and they negotiate from a weaker position.

Quality of Earnings Report Cost and Timeline

Cost and timing are the two questions most introductory guides dodge, so here are real ranges. For a business under $10 million in revenue, a quality of earnings report cost typically runs $25,000–$35,000. For larger or more complex businesses, fees often start around $60,000 and reach six figures, and a typical engagement runs four to eight weeks depending on complexity and the quality of the underlying records (Eton Venture Services, 2025). The single biggest swing factor is data readiness: clean, reconciled monthly accounts compress the timeline, while a disorganized data room extends it and inflates the fee.

When to Commission Diligence in the Deal Timeline

The most common timing mistake is waiting too long. Buyers who wait until the exclusivity window is nearly closed turn diligence into a fire drill: findings arrive with no time to investigate, no room to renegotiate, and only two options — close on faith or blow up the deal. Commission the QoE early enough that its findings can actually change something: the price, the structure, the indemnities, or the decision to walk. As a rule of thumb, kick off as soon as you have a signed LOI and basic data-room access, and sequence it so a draft lands well before key dates lock in.

For sellers, the logic inverts but points the same way: start before you go to market. A sell-side QoE done early lets you fix the problems a buyer would otherwise discover and weaponize — and it is one pillar of broader sell-side readiness. Whichever side you sit on, the value of diligence is highest when there is still room to act on it.

Where Senior Judgment Plus AI-Native Testing Changes What a QoE Catches

The quality of a QoE is decided by two things: how much of the data actually gets examined, and how good the judgment is on what that data means. Thin, junior-staffed reports fail on both — they sample lightly and escalate rarely. This is precisely where a modern approach pulls ahead. AI-native tooling lets a team read entire general ledgers rather than samples, reconcile transaction-level detail at scale, and surface anomalies — duplicate vendors, round-number journals, period-end spikes — that a manual review simply runs out of hours to find. Industry reporting associates AI-assisted due diligence with 30–40% lower professional-service fees and document review up to 70% faster, and cites McKinsey for a corroborating 20–30% cost reduction (Open Ledger, 2025).

But speed and breadth are only half the equation, and on their own they are dangerous. An anomaly is not a finding; a flag is not a conclusion. The judgment calls — is this add-back defensible? does this revenue recur? is this a debt-like item? — are exactly where deals are won and lost, and they cannot be automated. The right model is human-in-the-loop: AI widens what gets examined, and senior practitioners own every conclusion. That is how OpsFi runs financial due diligence — AI-native testing for thoroughness and consistency, with experienced people, not juniors, applying judgment and sign-off at each step. The tooling makes the work faster and more complete. The conclusions are ours, and they are written to be defended in committee.
