Financial Statement Analysis

Quality of Earnings Analysis: A Diligence Guide

A quality of earnings (QoE) analysis tests whether a company's reported earnings are accurate, sustainable and backed by cash. It normalizes EBITDA for nonrecurring and non-operating items, verifies revenue and margins against source data, reconciles earnings to cash, and assesses working capital and debt-like items. Buyers and lenders use the result to set price and size debt.

What is a quality of earnings analysis?

A quality of earnings analysis is a diligence exercise that examines whether a company's historical earnings are a reliable basis for valuation and lending. It is not an audit and does not issue an opinion on the financial statements. Instead, it asks practical questions: are the earnings real, are they recurring, are they supported by cash, and what level of earnings should a buyer or lender rely on going forward? The output is typically a report showing reported EBITDA, each diligence adjustment with support, and a resulting adjusted EBITDA figure.

QoE work is most common in acquisitions and leveraged financings, where small differences in EBITDA are multiplied into large differences in price and debt. A seller may commission one before a sale to identify issues early and support the asking price; a buyer or lender commissions its own to test the seller's figures independently. The scope is usually the trailing twelve months and two prior fiscal years, which allows trends and seasonality to be examined rather than relying on a single snapshot.

What does a QoE review examine?

The core of the analysis is the EBITDA bridge from reported figures to diligence-adjusted figures. Each adjustment falls into one of a few categories: normalization of owner or related-party items, removal of genuinely nonrecurring costs or gains, correction of accounting errors or policy inconsistencies, and pro forma adjustments for changes such as a new contract or a closed location. The reviewer tests each adjustment against documents and decides whether it is accepted, modified or rejected, and explains why. The summary should show the net effect by category so readers can see which judgments matter most.

Beyond the bridge, a thorough QoE examines revenue by customer, product and month to identify concentration, pricing changes and unusual period-end activity. It analyzes gross margin trends for cost capitalization or inventory issues, tests whether accruals are complete, reviews headcount and payroll for open positions or under-market compensation, and reconciles reported earnings to bank deposits. It also identifies debt-like items and normalized working capital, both of which affect the price the buyer ultimately pays. Each of these workstreams can surface issues that affect not only EBITDA but also the structure of the purchase agreement, including specific indemnities, escrows and representations tailored to the risks found.

• Revenue: concentration, cutoff, credits and returns, customer churn
• Margins: inventory costing, capitalized costs, vendor rebates
• Expenses: accrual completeness, related-party charges, under-market pay
• Cash: proof of cash, deposits versus revenue, timing of collections
• Balance sheet: working capital trend, debt-like items, contingencies

How do you test whether earnings are backed by cash?

A proof of cash compares revenue and expenses recorded in the general ledger with deposits and disbursements shown on bank statements, adjusted for changes in receivables, payables and other timing items. It is one of the most effective diligence procedures because bank records come from a third party and are difficult to manipulate. Large unexplained differences may indicate fictitious revenue, unrecorded liabilities, commingled personal funds or simply poor bookkeeping, and each possibility has different implications for the transaction. Where the business uses multiple bank accounts, all of them should be included, along with transfers between accounts and any accounts held by related entities.

A related analysis compares EBITDA with operating cash flow over several periods. A business whose EBITDA consistently exceeds cash conversion, after accounting for growth in working capital and capex, deserves scrutiny. Persistent gaps can come from aggressive revenue recognition, slow-paying customers, capitalized operating costs or inventory build. Conversion rates should be explained by the business model rather than accepted at face value, and the explanation should be consistent with what the reviewer sees in the working capital trends. Seasonal businesses require particular care, since a single period can show distorted conversion.

How do QoE findings affect valuation and debt sizing?

Because purchase prices and loan amounts are usually expressed as multiples of EBITDA, every dollar of adjustment is magnified. A reduction in adjusted EBITDA at a given multiple reduces enterprise value by the adjustment times the multiple, and reduces debt capacity by the adjustment times the leverage multiple. QoE findings therefore drive price renegotiation, changes in deal structure such as earnouts or escrows, and changes in loan amount or covenant levels. Because the effect is multiplied, even modest adjustments can justify a meaningful change in price or terms, and the parties often negotiate over individual adjustments for that reason.

Findings outside EBITDA matter as well. Debt-like items identified in the QoE, such as deferred revenue that requires future service without cash, unpaid bonuses, customer deposits, or deferred capex, reduce the equity purchase price dollar for dollar in a typical cash-free, debt-free deal. A normalized working capital analysis establishes the peg that protects the buyer from a seller who runs down receivables or stretches payables before closing. These items can be as valuable to the buyer as EBITDA adjustments, even though they attract less attention.

What are common red flags in a quality of earnings review?

Some patterns recur across transactions. Revenue spikes in the final month of a period, increasing credits and returns after period end, and receivables growing faster than revenue suggest pull-forward or aggressive recognition. Declining reserves for bad debts or inventory obsolescence while volumes grow may indicate earnings management. Margins that improve as capitalized costs rise deserve investigation, as do frequent changes in accounting policies or estimates. Each should be explored with management and supporting evidence before conclusions are drawn. Unusual journal entries posted after period end, especially manual entries to revenue or reserves, are another pattern worth testing directly in the general ledger.

Add-back patterns are another warning sign. A long list of one-time items that reappear every year, large pro forma adjustments for savings not yet realized, and adjustments that are not supported by contracts or invoices all reduce confidence in the adjusted figure. Related-party transactions, such as rent paid to an owner-controlled entity at off-market rates, should be restated to market terms. Finally, a business whose management resists providing source data or detail beneath summary schedules warrants additional caution throughout the diligence process.

Bridging management EBITDA to diligence-adjusted EBITDA

1. Reported EBITDA = $12.00 million. Management presents adjusted EBITDA of $13.50 million, adding $1.50 million of pro forma synergies and run-rate savings.
2. Diligence adjustments to reported EBITDA: owner compensation above market +$0.60 million; one-time litigation settlement +$0.40 million; revenue pulled forward from the next period -$0.50 million; inventory reserve shortfall -$0.30 million; run-rate cost of a required CFO hire -$0.25 million. Pro forma synergies are not accepted.
3. Diligence-adjusted EBITDA = 12.00 + 0.60 + 0.40 - 0.50 - 0.30 - 0.25 = $11.95 million.
4. Gap versus management figure = 13.50 - 11.95 = $1.55 million.
5. At a 9.0x purchase multiple, the valuation effect = 1.55 x 9.0 = $13.95 million.
6. At 4.0x senior leverage, supportable debt falls by 1.55 x 4.0 = $6.20 million.

How underwriters apply this

• Size debt and price on diligence-adjusted EBITDA, with every adjustment tied to documents and labeled accepted, modified or rejected.
• Require a proof of cash and a multi-period EBITDA to cash flow reconciliation before relying on the earnings base.
• Separate pro forma and synergy adjustments from historical normalizations and treat the former as upside, not base case.
• Capture debt-like items and a normalized working capital peg in the purchase agreement, not only in the EBITDA bridge.
• Track recurring one-time items across years; anything that recurs belongs in run-rate expenses.
