Quality of earnings analysis is the institutional examination that tests whether reported EBITDA is sustainable, transferable, and defensible. Capital does not read EBITDA as a single number. It reads it across eight adjustment categories, and each category is a place where value is either defended or surrendered.
Across $20M to $100M operators going to market, 40 to 55 percent reach the Letter of Intent stage with reported EBITDA that fails buy-side review, and the cost surfaces as 8 to 18 percent EBITDA repricing. This article walks through all eight categories, a worked example for each, the full adjustments checklist, and how the EBITDA Quality Calculator scores every dimension before diligence pressure begins.
Quality of earnings analysis is the institutional examination of reported EBITDA across eight adjustment categories: owner compensation, personal expenses, non-recurring items, run-rate adjustments, revenue recognition, cost accounting, customer concentration, and working capital trend. The analysis tests whether EBITDA is sustainable, transferable, and defensible under buyer scrutiny.
Institutional capital examines the same eight categories in every quality of earnings analysis, and each one carries its own operator gap frequency and its own EBITDA defense range. Select a category to read what capital examines, how the adjustment is built, and a worked example on an illustrative operator. The category an operator leaves undefended is the category a buyer reprices in diligence.
Owner compensation normalization replaces the actual compensation paid to the owner and any family on payroll with the market cost of the roles performed. Institutional capital benchmarks each role against market salary data and removes any family payroll that does not correspond to a real role. The adjustment moves EBITDA up where the owner overpaid themselves and down where they underpaid, and only the documented, defensible direction survives buy-side examination.
An owner draws 450 thousand dollars while the market cost of a general manager performing the same role is 220 thousand dollars. A spouse on payroll at 90 thousand dollars performs no identifiable role. The normalization adds back 230 thousand dollars of excess owner pay and removes the 90 thousand dollar family salary as a personal item.
The institutional methodology for quality of earnings analysis across the eight adjustment categories capital examines, from owner compensation through working capital trend.
Replace actual owner and family compensation with the market cost of the roles performed, because the adjustment is the difference between what the owner paid themselves and what a hired manager would cost.
Separate genuinely personal costs, including vehicles, travel, and family services run through the business, from operating expenses, and document each before claiming it as an add-back.
Identify litigation costs, restructuring charges, and one-time gains or losses that will not repeat under new ownership, and test that each is genuinely non-recurring rather than recurring under another label.
Adjust trailing earnings for pricing changes, contract wins, and contract losses that have occurred but are not yet fully reflected in the trailing twelve months, with documented support for each event.
Examine cut-off discipline, deferred revenue, and milestone recognition to confirm that reported revenue reflects earned performance rather than timing that flatters the period.
Test inventory valuation, cost of goods sold, and gross margin stability, because volatile or inconsistent cost accounting signals earnings that may not be sustainable.
Measure the revenue share of the top customer and the top five customers, because concentration above institutional thresholds discounts EBITDA regardless of how clean the adjustments are.
Normalize the working capital requirement for seasonality and trend, because an undefended working capital trend is one of the largest sources of post-LOI repricing.
The quality of earnings adjustments checklist covers all eight categories with the operator gap frequency and the EBITDA defense range for each. The combined defense range across the eight categories accounts for the 8 to 18 percent of EBITDA that repricing harvests when the categories are left undefended. Each item requires documented evidence to survive institutional review.
| Adjustment Category | What Capital Examines | Typical Operator Gap | EBITDA Defense Range |
|---|---|---|---|
| Owner Compensation Normalization | Market vs actual comp, family payroll | 60 to 75% understate | 3 to 8% |
| Personal Expenses | Vehicles, travel, family services | 50 to 65% incomplete | 2 to 6% |
| Non-Recurring Items | Litigation, restructuring, one-time gains | 40 to 55% misclassified | 4 to 10% |
| Run-Rate Adjustments | Pricing changes, contract wins and losses | 70 to 85% unsupported | 5 to 12% |
| Revenue Recognition Treatment | Cut-off, deferred revenue, milestones | 45 to 60% inconsistent | 3 to 8% |
| Cost Accounting Reliability | Inventory, COGS, gross margin | 50 to 65% volatile | 4 to 10% |
| Customer Concentration | Top customer and top five revenue share | Always examined | 6 to 15% |
| Working Capital Trend | Normalized WC, seasonality | 70 to 85% undefended | 8 to 18% |
The eight categories do not carry equal weight. Working capital trend and customer concentration carry the largest exposure, while personal expenses and revenue recognition carry the smallest. The ranking tells an operator where to concentrate the preparation that defends the most EBITDA before the LOI sets a number.

The EBITDA Quality Calculator scores each of the eight adjustment categories, identifies which adjustments are defensible and which carry repricing exposure, and produces a directional read on EBITDA quality before a full quality of earnings examination begins. It converts the eight-category framework into a quantified score an operator controls.
Scoring a single add-back is arithmetic. Scoring all eight categories against the standard a buyer will apply is the work, and that is what the EBITDA Quality Calculator is built to do. It reads each category, flags the operator gap, and ranges the defended EBITDA, so the operator sees the full exposure before a buyer anchors the LOI. Read against the Financial Truth Ladder, the score shows how far each adjustment will carry given the rung the business occupies.
The eighth category, working capital trend, is quantified separately in the Working Capital Peg Calculator, because the seasonality overlay it requires is its own discipline. The full examination across all eight categories is completed through pre-transaction finance preparation and the QofE Pre-Read, with definitions for every line held in the glossary. Begin in the Operating Library, then defend the EBITDA capital examines.
The eight categories are scored, evidenced, and defended before the LOI sets a number. Score the categories in the EBITDA Quality Calculator, or open the preparation engagement.
