Quality of Earnings: What It Is and Why Buyers Require It

The Document That Makes or Breaks the Deal

A quality of earnings report is a financial due diligence analysis that examines the sustainability and accuracy of a company's reported earnings. In M&A transactions, the buy-side QoE has become the standard — virtually every private equity buyer and most strategic acquirers commission one before finalizing a purchase price.

The QoE's purpose is simple: determine whether the EBITDA the seller is claiming is real, repeatable, and accurately represented. The analysis goes behind the financial statements to verify revenue quality, normalize one-time items, test accounting policies, and identify risks that the trailing financials don't show on their surface.

When the QoE confirms the seller's numbers, the deal moves forward at or near the agreed price. When it reveals material adjustments — and it frequently does — the price gets renegotiated, the deal structure changes, or the transaction collapses entirely. More deals die in quality of earnings than at any other stage of due diligence.

What a QoE Examines

Revenue quality. Not all revenue is created equal. The QoE analyzes customer concentration, contract terms, recurring vs. one-time revenue, related-party transactions, and revenue recognition timing. A business showing $8 million in revenue with 40% coming from a single customer and 25% from a one-time project will be assessed very differently from one with diversified, recurring revenue at the same level.

EBITDA normalization. The seller's adjusted EBITDA typically includes add-backs for owner compensation, one-time expenses, and non-recurring items. The QoE tests every add-back. Is the owner's above-market salary truly above market, or is the "excess" smaller than claimed? Is the one-time legal expense truly one-time, or does the company face similar litigation regularly? Are the "non-recurring" consulting fees actually recurring operational expenses that were reclassified?

Working capital analysis. The QoE establishes a normalized working capital target — the level of net working capital needed to operate the business at its current revenue level. Deviations from this target at closing result in purchase price adjustments. Sellers who have been managing working capital aggressively (accelerating collections, delaying payables) will see that unwound in the QoE analysis.

Common Red Flags

Certain patterns trigger heightened scrutiny in every QoE analysis. Revenue concentration above 20% in any single customer raises sustainability questions. Rapid revenue growth in the trailing twelve months — particularly if it coincides with the decision to sell — invites examination of whether the growth is organic or manufactured. Significant related-party transactions require arm's-length verification.

On the expense side, inconsistent add-back treatment is the most common red flag. If the seller adds back a "one-time" expense that appears in three of the last five years, the QoE will reclassify it as recurring. If owner benefits are added back but replacement cost estimates are understated, the adjustment works against the seller. Every line item the seller highlights as non-recurring will be tested against historical patterns.

Financial statement quality itself can be a red flag. Businesses using cash-basis accounting, inconsistent chart-of-accounts structures, or manual spreadsheet-based bookkeeping create more work for the QoE team — and more uncertainty in the conclusions. The additional time and cost of the analysis often translates into more conservative buyer assumptions.

The Sell-Side QoE Advantage

A sell-side quality of earnings report — commissioned by the seller before going to market — is one of the most effective tools for protecting deal value. The concept is simple: identify and address the issues before the buyer's team finds them.

When a seller presents a sell-side QoE to prospective buyers, it signals preparation, transparency, and confidence in the numbers. Buyers still conduct their own analysis, but the sell-side report sets the baseline. Issues that would have been "surprises" discovered in due diligence become disclosed items that have already been addressed or explained.

The practical impact is significant. Sell-side QoE engagements typically cost $30,000 to $75,000 — a fraction of the $200,000 to $500,000 in deal value that a single unexpected EBITDA adjustment can destroy. The return on investment is among the highest of any pre-transaction expenditure.
