How to Analyze the Quality of Earnings of a Business: A Complete Guide

Quality of Earnings (QoE) analysis is one of the most important financial diligence tools used in mergers and acquisitions, private equity transactions, business sales, and investment decisions.

The purpose of a QoE analysis is not simply to confirm how much EBITDA a company reports.

Instead, it asks a deeper question:

How much of the company’s reported earnings are truly recurring, sustainable, and representative of future operating performance?

This distinction matters because two businesses may report the same EBITDA while having very different levels of revenue quality, customer concentration, cash conversion, capital requirements, and accounting risk.

A strong QoE analysis helps buyers, investors, lenders, and sellers understand the economic reality behind reported financial performance.

What Is Quality of Earnings?

Quality of Earnings refers to the degree to which reported earnings reflect the company’s underlying, sustainable operating performance.

High-quality earnings are generally:

• Recurring
• Supported by normal business operations
• Converted into cash
• Consistent with accounting policies
• Not heavily dependent on one-time gains or unusual adjustments

Low-quality earnings may be influenced by:

• One-time revenue
• Aggressive accounting policies
• Unsupported EBITDA add-backs
• Temporary cost reductions
• Customer concentration
• Weak cash conversion
• Deferred expenses

Why Quality of Earnings Matters in M&A

Many acquisitions are priced using an EBITDA multiple.

If the EBITDA figure used in the valuation is overstated, the buyer may materially overpay.

For example, assume a seller reports EBITDA of $20 million and the agreed valuation multiple is 9.0x.

The implied Enterprise Value would be:

$20 million × 9.0 = $180 million

If Quality of Earnings analysis later determines that sustainable EBITDA is only $17 million:

$17 million × 9.0 = $153 million

Metric	Seller Case	QoE Case
EBITDA	$20 million	$17 million
Valuation Multiple	9.0x	9.0x
Enterprise Value	$180 million	$153 million
Difference	$27 million

This illustrates why relatively small earnings adjustments can have a significant impact on transaction value.

Quality of Earnings vs Audit

A Quality of Earnings analysis is different from a financial statement audit.

Financial Audit	Quality of Earnings Analysis
Focuses on whether financial statements are fairly presented.	Focuses on whether earnings are sustainable and transaction-relevant.
Based on accounting standards.	Based on transaction economics.
Usually examines historical reporting accuracy.	Examines normalized future earnings capacity.
May not focus heavily on EBITDA add-backs.	Typically scrutinizes EBITDA adjustments in detail.

A company can have audited financial statements and still have significant QoE issues from an acquisition perspective.

Quality of Earnings vs Financial Due Diligence

Quality of Earnings is often a major component of financial due diligence, but the two terms are not always identical.

Financial due diligence may include:

• Quality of Earnings
• Working capital analysis
• Debt and debt-like items
• Cash flow analysis
• Capital expenditure review
• Balance sheet analysis
• Financial forecast review

QoE typically focuses more specifically on the sustainability and quality of reported earnings.

Step 1: Start with Reported EBITDA

The analysis usually begins with reported EBITDA from the company’s financial statements or management accounts.

Assume the target reports:

• Revenue: $100 million
• Reported EBITDA: $15 million
• EBITDA Margin: 15%

The objective is then to determine whether the $15 million figure accurately represents recurring operating earnings.

Step 2: Build an EBITDA Bridge

A QoE analysis often uses an EBITDA bridge showing how reported earnings move to normalized earnings.

Illustrative EBITDA Bridge

Adjustment	Amount
Reported EBITDA	$15.0 million
Add: One-Time Legal Expense	+$0.8 million
Add: Transaction-Related Fees	+$0.5 million
Add: Excess Owner Compensation	+$0.4 million
Less: One-Time Revenue Benefit	($1.2 million)
Less: Understated Ongoing Payroll Cost	($0.6 million)
Normalized EBITDA	$14.9 million

The key issue is not whether adjustments increase or decrease EBITDA.

The key issue is whether each adjustment is economically supportable.

What Is Normalized EBITDA?

Normalized EBITDA is an estimate of sustainable operating earnings after adjusting for items that are not representative of normal ongoing operations.

Potential adjustments may include:

• One-time legal costs
• Transaction expenses
• Owner-related expenses
• Non-recurring gains
• Temporary cost savings
• Unusual bonuses
• Restructuring charges

However, not every unusual expense should automatically be added back.

Step 3: Test Whether Add-Backs Are Truly Non-Recurring

Sellers often present adjusted EBITDA that includes numerous add-backs.

A buyer should test whether those costs are genuinely non-recurring.

For example, if a company incurs restructuring expenses every year, they may be part of the normal cost of operating the business rather than a one-time item.

Example

Year	Restructuring Expense
Year 1	$0.7 million
Year 2	$0.9 million
Year 3	$0.8 million

Calling Year 3 restructuring expense “one-time” may be difficult to justify when similar costs occur repeatedly.

Step 4: Analyze Owner-Related Adjustments

Privately held companies may include expenses related to owners rather than normal market operations.

Potential adjustments may include:

• Excess owner compensation
• Personal travel
• Personal vehicles
• Family salaries
• Related-party expenses

However, buyers should also consider replacement costs.

Illustrative Owner Compensation Adjustment

Assume the owner receives compensation of $900,000.

A market-rate replacement executive would cost $500,000.

The appropriate potential adjustment is:

$900,000 − $500,000 = $400,000

Removing the entire $900,000 would overstate normalized EBITDA because the company still requires executive leadership.

Step 5: Identify Non-Recurring Revenue

Quality of Earnings analysis does not focus only on expenses.

Revenue also needs to be normalized.

Potential non-recurring revenue may include:

• Large one-time projects
• Insurance recoveries
• Settlement income
• Temporary government programs
• Unusual customer orders

Illustrative Revenue Adjustment

Assume the company generated $5 million from a one-time project that will not recur.

If the EBITDA margin on that project was 25%, the contribution to EBITDA was approximately:

$5 million × 25% = $1.25 million

A buyer may remove this amount when estimating sustainable earnings.

Step 6: Analyze Revenue Quality

Revenue quality is a major part of QoE analysis because not all revenue has the same level of predictability.

Investors may evaluate:

• Recurring revenue
• Contracted revenue
• Repeat customer revenue
• Project-based revenue
• Customer churn
• Pricing stability

Illustrative Revenue Mix

Revenue Type	Percentage
Recurring Contract Revenue	65%
Repeat Non-Contract Revenue	25%
One-Time Revenue	10%

A business with a higher percentage of predictable recurring revenue may support greater confidence in normalized earnings.

Step 7: Review Revenue Recognition

Aggressive revenue recognition can temporarily increase earnings.

QoE analysis may examine:

• Timing of revenue recognition
• Contract milestones
• Deferred revenue
• Returns and credits
• Cut-off procedures

The objective is to determine whether reported revenue was earned in the appropriate period and is likely to convert into cash.

Step 8: Analyze Customer Concentration

A company may report strong earnings while depending heavily on one or two customers.

Assume:

Customer Group	Revenue Contribution
Largest Customer	24%
Top 3 Customers	48%
Top 10 Customers	72%

High concentration does not automatically mean earnings are poor quality, but it increases the risk that current earnings may not be sustainable.

Step 9: Review Customer Retention

Revenue growth can hide customer churn if new sales replace lost customers.

QoE analysis may therefore review:

• Customer retention
• Revenue retention
• Customer churn
• Renewal rates
• Cohort performance

Strong retention can support confidence in future earnings, while high churn may weaken the quality of current revenue.

Step 10: Analyze Gross Margin Trends

Gross margin trends can reveal whether EBITDA growth is sustainable.

Year	Revenue	Gross Margin
Year 1	$80M	42%
Year 2	$90M	40%
Year 3	$100M	36%

Revenue is growing, but declining gross margins may indicate pricing pressure, input cost inflation, or unfavorable customer mix.

This can affect the sustainability of EBITDA.

Step 11: Analyze Expense Sustainability

A company may temporarily improve EBITDA by reducing expenses that will need to return later.

Examples include:

• Delayed hiring
• Reduced marketing spend
• Deferred maintenance
• Temporary salary reductions
• Underinvestment in technology

QoE analysis should identify whether current expenses are representative of the ongoing cost structure required to maintain the business.

Step 12: Review Cash Conversion

High-quality earnings should generally have reasonable cash conversion.

EBITDA that does not convert into cash may require closer review.

Illustrative Cash Conversion

Item	Amount
Normalized EBITDA	$15 million
Cash Taxes	($2 million)
Capital Expenditures	($4 million)
Working Capital Investment	($5 million)
Indicative Pre-Debt Cash Flow	$4 million

Although EBITDA is $15 million, only approximately $4 million remains after major operating cash requirements in this simplified example.

This can materially affect valuation and debt capacity.

Why EBITDA Is Not the Same as Cash Flow

EBITDA does not account for several important cash requirements, including:

• Capital expenditures
• Working capital
• Cash taxes
• Interest expense

QoE analysis therefore benefits from evaluating both earnings and cash generation.

Initial Quality of Earnings Checklist

At the beginning of a QoE review, buyers and investors should understand:

• Reported EBITDA
• Seller adjustments
• Normalized EBITDA
• Revenue quality
• Customer concentration
• Customer retention
• Gross margin trends
• Cash conversion
• Working capital
• Capital expenditure requirements

What Comes Next

After reviewing the initial EBITDA and revenue quality, the next stage of a comprehensive Quality of Earnings analysis typically examines:

• Working capital trends
• Accounts receivable
• Inventory
• Capital expenditures
• Deferred expenses
• Aggressive accounting policies
• Buyer vs seller adjustments
• Impact on purchase price

Key Takeaway

Quality of Earnings analysis is designed to determine whether reported earnings reflect sustainable economic performance. The process begins with reported EBITDA and then evaluates legitimate add-backs, one-time revenue, owner-related expenses, revenue quality, customer concentration, gross margins, expense sustainability, and cash conversion. The objective is not to maximize or minimize EBITDA, but to identify the level of earnings that a buyer or investor can reasonably expect the business to generate on an ongoing basis. Because valuation multiples are often applied directly to normalized EBITDA, a disciplined QoE analysis can materially affect acquisition price, financing capacity, and investment returns.

Step 13: Analyze Working Capital Quality

Working capital is an important part of Quality of Earnings analysis because reported EBITDA can appear strong while the business consumes significant cash through receivables, inventory, or other operating assets.

Buyers generally evaluate whether the company requires a normal and sustainable level of working capital to support its operations.

Common working capital accounts include:

• Accounts receivable
• Inventory
• Accounts payable
• Accrued operating expenses
• Other operating current assets and liabilities

Why Working Capital Matters

A business may report improving EBITDA while also experiencing deteriorating collections or increasing inventory requirements.

This can reduce cash flow quality.

Illustrative Working Capital Trend

Metric	Year 1	Year 2	Year 3
Revenue	$80M	$90M	$100M
Accounts Receivable	$10M	$14M	$20M
Inventory	$8M	$10M	$15M

Revenue has grown 25%, but receivables have doubled and inventory has increased significantly faster than sales.

This may indicate weakening cash conversion or operational inefficiencies.

Step 14: Review Accounts Receivable

Accounts receivable analysis helps determine whether reported revenue is converting into collectible cash.

QoE professionals may examine:

• Days Sales Outstanding
• Accounts receivable aging
• Bad debt history
• Customer disputes
• Post-period collections

Illustrative Receivable Aging

Aging Bucket	Balance
Current	$8.0M
31–60 Days	$3.0M
61–90 Days	$1.5M
90+ Days	$2.5M
Total Accounts Receivable	$15.0M

A large 90+ day balance may suggest collection risk or overly aggressive revenue recognition.

Step 15: Analyze Inventory Quality

Inventory can materially affect cash flow and earnings quality, particularly in manufacturing, distribution, and retail businesses.

Areas of review may include:

• Inventory turnover
• Obsolete inventory
• Slow-moving inventory
• Inventory write-downs
• Purchasing patterns

If obsolete inventory has not been properly reserved, reported earnings and working capital may both be overstated.

Step 16: Review Accounts Payable

A company can temporarily improve cash flow by delaying payments to suppliers.

QoE analysis may therefore review whether accounts payable has increased unusually relative to normal operations.

Buyers may examine:

• Days Payable Outstanding
• Supplier aging
• Overdue balances
• Supplier disputes
• Unrecorded liabilities

An unusually high payable balance may indicate that current cash flow is temporarily overstated.

Step 17: Determine Normalized Working Capital

In many acquisitions, the buyer expects the company to be delivered with a normal level of working capital.

The QoE process may therefore help establish a normalized working capital target.

Illustrative Working Capital Target

Period	Net Working Capital
Year 1 Average	$10.5M
Year 2 Average	$11.2M
Year 3 Average	$12.0M

The transaction parties may conclude that approximately $11.5–$12.0 million represents a normal working capital requirement, subject to seasonality and recent operating trends.

How Working Capital Can Affect Purchase Price

Assume the agreed target is $12 million, but closing working capital is only $9.5 million.

The shortfall is:

$12.0 million − $9.5 million = $2.5 million

Depending on the purchase agreement, the seller’s consideration may be reduced by approximately $2.5 million.

Step 18: Analyze Capital Expenditures

Capital expenditures are another important factor when evaluating earnings quality.

EBITDA excludes CapEx, but many businesses require ongoing investment in assets to maintain existing earnings.

QoE analysis may distinguish between:

• Maintenance CapEx
• Growth CapEx

Maintenance CapEx vs Growth CapEx

Maintenance CapEx represents investment required to sustain current operations.

Growth CapEx represents investment intended to expand future capacity or revenue.

This distinction matters because maintenance CapEx is effectively an ongoing cash requirement associated with sustaining current earnings.

Illustrative CapEx Analysis

Year	Total CapEx	Estimated Maintenance CapEx
Year 1	$4.0M	$3.0M
Year 2	$5.0M	$3.2M
Year 3	$2.0M	$3.5M

Year 3 spending is materially below estimated maintenance requirements.

This may indicate deferred investment rather than permanently improved cash flow.

Step 19: Identify Deferred Expenses

A company may improve current-period EBITDA by postponing expenses that will eventually need to be incurred.

Examples include:

• Deferred maintenance
• Delayed hiring
• Reduced marketing
• Delayed technology upgrades
• Temporary vendor concessions

These items may not appear as formal accounting adjustments, but they can still affect sustainable earnings.

Step 20: Review Payroll and Headcount

Payroll is often one of the largest operating expenses in a business.

QoE analysis may evaluate whether current headcount is sufficient to support the reported revenue level.

For example, if the company has delayed hiring several critical employees, current EBITDA may be temporarily elevated.

Illustrative Payroll Normalization

Item	Annual Cost
Current Payroll	$18.0M
Required Open Positions	$1.2M
Market Compensation Adjustment	$0.5M
Normalized Payroll	$19.7M

If these additional costs are required to maintain current operations, normalized EBITDA may need to be reduced.

Step 21: Review Accounting Policies

Accounting policies can materially affect the timing and presentation of earnings.

A QoE review may examine policies related to:

• Revenue recognition
• Expense capitalization
• Inventory valuation
• Bad debt reserves
• Accrued expenses
• Warranty reserves

The objective is to identify whether the financial statements contain accounting choices that make earnings appear stronger than the underlying economics.

Step 22: Identify Aggressive Expense Capitalization

Capitalizing expenses rather than recording them immediately can increase current-period EBITDA or operating profit.

Potential areas may include:

• Software development
• Implementation costs
• Project expenses
• Internal labor

Buyers should determine whether capitalization policies are appropriate and consistent with normal accounting practices.

Step 23: Review Accrued Expenses

Understated accrued liabilities can temporarily increase earnings.

QoE analysis may review:

• Employee bonuses
• Commissions
• Vacation accruals
• Professional fees
• Utilities
• Taxes

If material expenses have not been properly accrued, normalized EBITDA may require adjustment.

Step 24: Analyze Monthly Financial Trends

Annual financial statements can hide important fluctuations.

Quality of Earnings analysis often examines monthly results to identify:

• Seasonality
• Quarter-end adjustments
• Unusual revenue spikes
• Margin volatility
• Expense timing

Illustrative Monthly EBITDA

Month	EBITDA
January	$1.0M
February	$1.1M
March	$1.0M
April	$1.2M
May	$1.1M
June	$2.5M

The unusually high June result may require investigation to determine whether it reflects normal operations or a one-time event.

Step 25: Compare EBITDA with Cash Flow

A persistent gap between EBITDA and operating cash flow can be an important QoE warning sign.

For example:

Year	EBITDA	Operating Cash Flow
Year 1	$12M	$10M
Year 2	$14M	$9M
Year 3	$16M	$7M

EBITDA is increasing, but operating cash flow is declining.

This pattern could result from working capital growth, aggressive accounting, or rising capital requirements.

Step 26: Analyze Earnings Consistency

Stable and predictable earnings may be considered higher quality than highly volatile earnings.

Professionals may review:

• Monthly EBITDA volatility
• Customer concentration
• Seasonality
• Project timing
• Recurring revenue

A company with highly volatile results may warrant more conservative valuation assumptions even if average EBITDA appears attractive.

Step 27: Analyze Growth Quality

Growth itself should also be evaluated for quality.

Revenue can grow through:

• Organic customer growth
• Pricing
• Acquisitions
• One-time projects
• Temporary market conditions

Organic, recurring growth may generally provide stronger evidence of sustainable earnings than temporary or acquisition-driven growth.

Step 28: Review Management Forecast Accuracy

Historical forecast accuracy can help buyers determine how much confidence to place in management’s projections.

Year	Budget EBITDA	Actual EBITDA
Year 1	$12M	$11.8M
Year 2	$14M	$13.5M
Year 3	$17M	$14.2M

A significant recent forecasting miss may justify more conservative assumptions about future performance.

Common Quality of Earnings Red Flags

Several issues may indicate lower earnings quality:

• Large number of EBITDA add-backs
• Recurring items described as one-time
• Declining cash conversion
• Rapid growth in receivables
• Increasing inventory
• Deferred maintenance
• High customer concentration
• Falling gross margins
• Aggressive revenue recognition
• Repeated forecast misses

One Red Flag Does Not Automatically Mean Poor Quality

A Quality of Earnings conclusion should consider the complete financial picture.

For example, high working capital requirements may be normal for a particular industry.

Similarly, customer concentration may be manageable if long-term contracts and high switching costs provide strong revenue visibility.

The objective is to understand the economic significance of each issue rather than applying rigid rules.

Illustrative QoE Risk Scorecard

Area	Assessment
Revenue Quality	Strong
Customer Concentration	Moderate Risk
EBITDA Adjustments	Moderate
Cash Conversion	Weak
Working Capital	Increasing
CapEx Requirements	Moderate
Accounting Policies	Acceptable

How QoE Findings Flow into Valuation

The results of the QoE review should not remain isolated in a diligence report.

They should flow directly into:

• Normalized EBITDA
• Valuation multiples
• LBO models
• Debt capacity
• Working capital targets
• Purchase price negotiations

This ensures that the valuation reflects the financial reality identified during diligence.

Key Takeaway

A comprehensive Quality of Earnings analysis extends beyond EBITDA add-backs. Buyers should evaluate working capital, receivables, inventory, payables, capital expenditures, payroll, accounting policies, monthly financial trends, cash conversion, and management forecast accuracy. These areas help determine whether current earnings are sustainable and whether reported profitability converts into real economic cash flow. The strongest QoE analysis connects its findings directly to valuation, debt capacity, working capital targets, and purchase price negotiations rather than treating financial diligence as a separate exercise.

Step 29: Understand Buyer vs Seller Quality of Earnings Perspectives

Quality of Earnings analysis can look different depending on whether it is prepared for a buyer or a seller.

A buyer generally wants to identify risks that could reduce sustainable earnings, increase required working capital, or lower the appropriate purchase price.

A seller generally wants to present the company’s earnings in a clear and supportable manner before entering the transaction process.

Buy-Side Quality of Earnings

A buy-side QoE is performed on behalf of a potential acquirer or investor.

The analysis typically focuses on:

• Validating reported EBITDA
• Challenging seller add-backs
• Identifying non-recurring revenue
• Reviewing revenue quality
• Analyzing working capital
• Identifying debt-like items
• Assessing cash conversion
• Testing management forecasts

The objective is to help the buyer understand the financial performance it is actually acquiring.

Sell-Side Quality of Earnings

A sell-side QoE, sometimes referred to as vendor financial due diligence, is prepared before or during a sale process on behalf of the seller.

Its objectives may include:

• Identifying financial issues before buyers discover them
• Supporting normalized EBITDA adjustments
• Preparing a clear EBITDA bridge
• Documenting revenue trends
• Analyzing working capital
• Reducing transaction surprises

A well-prepared sell-side QoE can help management respond more efficiently to buyer diligence questions.

Buyer and Seller May Reach Different EBITDA Conclusions

Differences often arise because transaction participants may disagree about whether certain adjustments are recurring or sustainable.

Illustrative EBITDA Adjustment Comparison

Adjustment	Seller Position	Buyer Position
Legal Expense	+$1.0M	+$1.0M
Restructuring Cost	+$1.2M	+$0.4M
Future Cost Savings	+$1.5M	$0
One-Time Customer Revenue	$0	($0.8M)

The resulting normalized EBITDA could differ materially depending on which adjustments are accepted.

Step 30: Distinguish Historical Adjustments from Pro Forma Adjustments

Not all EBITDA adjustments represent historical normalization.

Some adjustments reflect future changes that have not yet fully occurred.

Examples include:

• Planned cost reductions
• Expected headcount savings
• Future facility closures
• Anticipated procurement savings

These are often described as pro forma adjustments rather than historical QoE adjustments.

Buyers may treat them more conservatively because execution has not yet been proven.

Illustrative Historical vs Pro Forma EBITDA

Metric	Amount
Reported EBITDA	$18.0M
Historical Normalization Adjustments	+$1.0M
Normalized EBITDA	$19.0M
Future Cost Savings	+$2.0M
Pro Forma EBITDA	$21.0M

A buyer may value the company using $19 million rather than $21 million if the future cost savings have not yet been achieved.

Step 31: Review Run-Rate Adjustments

Run-rate adjustments attempt to reflect the full-year impact of changes already implemented.

For example, assume the company reduces annual operating costs by $1.2 million beginning halfway through the year.

Only $600,000 of savings may appear in the historical financial statements.

A run-rate adjustment could potentially recognize the remaining $600,000 if the savings are fully implemented and sustainable.

Buyers should verify:

• The change has actually occurred.
• The savings are measurable.
• The cost will not return.
• There are no offsetting expenses.

Step 32: Analyze Related-Party Transactions

Privately held businesses may conduct transactions with owners, family members, or affiliated entities.

Examples include:

• Related-party rent
• Management fees
• Loans
• Shared employees
• Purchases from affiliated companies

QoE analysis should determine whether these transactions occur at market rates.

Illustrative Related-Party Rent Adjustment

Assume the company pays an owner-controlled real estate entity $1.5 million annually in rent.

Market rent for the property is estimated at $1.1 million.

A potential normalized EBITDA adjustment would be:

$1.5 million − $1.1 million = $400,000

Step 33: Identify One-Time Gains

One-time gains can increase reported EBITDA but may not represent sustainable performance.

Potential examples include:

• Insurance proceeds
• Settlement income
• Asset-related gains included in operating results
• Unusual supplier rebates
• Government assistance

These items may need to be removed from normalized earnings.

Step 34: Review Cost Savings Carefully

Sellers may present future cost-saving opportunities as EBITDA adjustments.

Buyers should ask:

• Has the initiative already been implemented?
• Are employees already terminated?
• Are contracts already renegotiated?
• Are implementation costs included?
• Could the savings affect revenue or service quality?

An identified opportunity is not necessarily the same as normalized historical EBITDA.

Step 35: Analyze Acquisition-Related Earnings

If the target has completed acquisitions, historical growth may include acquired revenue and EBITDA.

QoE analysis may separate:

• Organic growth
• Acquisition-driven growth
• Acquisition synergies

This distinction is especially important when the buyer is assessing the underlying growth profile of the company.

Step 36: Examine Synergy Adjustments

Buyer-specific synergies should generally be analyzed separately from Quality of Earnings.

Potential acquisition synergies may include:

• Duplicate management elimination
• Procurement savings
• Technology consolidation
• Cross-selling

These benefits may increase strategic value but are not necessarily part of the target’s standalone normalized EBITDA.

Step 37: Analyze Debt and Debt-Like Items

Although debt-like items are not always part of the normalized EBITDA calculation, they are often reviewed during the same financial diligence process.

Potential debt-like items may include:

• Accrued transaction expenses
• Unpaid employee bonuses
• Deferred compensation
• Tax liabilities
• Finance leases
• Litigation obligations

These items can reduce Equity Value even if they do not affect the agreed Enterprise Value.

Illustrative Enterprise Value to Equity Value Bridge

Item	Amount
Enterprise Value	$180M
Less: Bank Debt	($20M)
Less: Debt-Like Items	($5M)
Add: Excess Cash	$6M
Indicative Equity Value	$161M

Related Reading: How Debt and Cash Affect Transaction Value: A Complete Guide

Step 38: Measure the Purchase Price Impact of QoE

One of the most important outputs of Quality of Earnings analysis is understanding how diligence findings affect transaction value.

Assume:

• Seller Adjusted EBITDA: $22 million
• Buyer-Supported EBITDA: $19 million
• Agreed Valuation Multiple: 9.0x

Purchase Price Impact

Scenario	EBITDA	Enterprise Value at 9.0x
Seller Case	$22M	$198M
Buyer QoE Case	$19M	$171M
Potential Difference	$3M	$27M

The $3 million EBITDA difference translates into a $27 million difference in Enterprise Value.

QoE Can Affect More Than Purchase Price

Quality of Earnings findings may also affect:

• Debt financing
• Private equity returns
• Working capital targets
• Earnouts
• Transaction protections
• Investment Committee approval

Step 39: Evaluate the Impact on Debt Capacity

Lenders often base acquisition financing on EBITDA.

If lender leverage is capped at 4.0x EBITDA:

EBITDA	Potential Debt at 4.0x
$22M	$88M
$19M	$76M

A lower QoE-supported EBITDA could reduce debt capacity by $12 million.

The buyer may then need to contribute additional equity or renegotiate the purchase price.

Step 40: Evaluate the Impact on Private Equity Returns

Lower sustainable EBITDA can affect both entry valuation and projected LBO returns.

Potential effects include:

• Higher effective purchase multiple
• Lower debt financing
• More sponsor equity required
• Lower projected exit EBITDA
• Lower IRR and MOIC

This is why private equity firms typically incorporate final QoE findings directly into their investment models.

Step 41: Use QoE Findings in the Investment Committee Memo

An Investment Committee Memorandum may summarize:

• Seller Adjusted EBITDA
• QoE adjustments
• Buyer-supported normalized EBITDA
• Major revenue risks
• Working capital findings
• Cash conversion

Illustrative IC Summary

Financial Metric	Initial Case	Post-QoE Case
Adjusted EBITDA	$22M	$19M
Purchase Multiple	9.0x	10.4x
Debt Capacity	$88M	$76M

If the Enterprise Value remains unchanged at $198 million, the effective purchase multiple rises significantly after QoE adjustments.

Related Reading: What Is an Investment Committee Memorandum? A Complete Guide

Step 42: Decide Whether the Issue Should Change Price or Structure

Not every QoE finding needs to result in a direct reduction in headline purchase price.

Depending on the issue, buyers may respond through:

• Purchase price reduction
• Earnout
• Seller note
• Escrow
• Indemnification
• Working capital adjustment

The appropriate solution depends on whether the issue relates to permanent value, future uncertainty, or a specific liability.

Example: Using an Earnout to Bridge an EBITDA Disagreement

Assume the seller believes normalized EBITDA is $22 million, while the buyer supports only $19 million.

The parties may agree to:

• Value the business initially using the lower supported earnings level.
• Provide additional consideration if future EBITDA reaches agreed targets.

This allows part of the valuation disagreement to be resolved through actual future performance.

Step 43: Prioritize QoE Findings by Materiality

A professional QoE analysis should focus on issues that materially affect transaction economics.

Potential prioritization may include:

Finding	Potential Impact	Priority
Unsupported EBITDA Add-Back	$1.5M EBITDA	High
Largest Customer Churn Risk	Potential 15% Revenue Impact	High
Working Capital Shortfall	$2M Purchase Price Adjustment	High
Minor Expense Reclassification	$50K EBITDA	Low

This helps decision-makers focus attention on the issues that matter most.

Step 44: Create a Final QoE Bridge

The completed analysis should clearly reconcile reported financial performance to buyer-supported normalized earnings.

Illustrative Final QoE Bridge

Item	Amount
Reported EBITDA	$18.0M
Valid One-Time Expenses	+$1.2M
Owner Compensation Adjustment	+$0.4M
Non-Recurring Revenue	($0.8M)
Normalized Payroll	($0.5M)
Recurring Restructuring Costs	($0.3M)
Normalized EBITDA	$18.0M

Interestingly, normalized EBITDA in this example equals reported EBITDA, but the composition of earnings has changed materially.

This demonstrates that QoE is about understanding earnings quality, not simply increasing or reducing the headline figure.

Quality of Earnings Is Not Just an EBITDA Exercise

A complete analysis should provide insight into:

• Revenue sustainability
• Customer quality
• Cash conversion
• Working capital
• CapEx
• Accounting policies
• Debt-like items
• Financial forecasting reliability

Normalized EBITDA is important, but it is only one output of the overall financial diligence process.

Key Takeaway

Buyer and seller Quality of Earnings analyses may reach different conclusions because transaction participants often have different views of EBITDA adjustments, run-rate savings, future cost reductions, and revenue sustainability. A disciplined QoE review distinguishes historical normalization from unproven pro forma benefits, identifies debt-like obligations and working capital issues, and quantifies how earnings adjustments affect valuation, leverage, and investment returns. The most useful QoE findings flow directly into purchase price negotiations, transaction structure, financing, and Investment Committee analysis rather than remaining isolated in a diligence report.

Step 45: Build a Comprehensive QoE Findings Summary

After completing the detailed financial review, the findings should be consolidated into a clear summary that decision-makers can understand quickly.

A strong Quality of Earnings summary generally highlights:

• Reported EBITDA
• Normalized EBITDA
• Major accepted adjustments
• Major rejected adjustments
• Revenue quality
• Customer concentration
• Cash conversion
• Working capital
• Capital expenditure requirements
• Key financial risks

Illustrative QoE Summary

Area	Finding	Assessment
Normalized EBITDA	$18.0M	Supported
Recurring Revenue	72%	Strong
Largest Customer	21% of Revenue	Moderate Risk
Cash Conversion	55% of EBITDA	Moderate
Working Capital	Increasing	Requires Attention
Maintenance CapEx	$3.5M	Normal

This type of summary helps buyers and investors quickly identify the most important financial conclusions.

Step 46: Separate Earnings Quality from Business Quality

Quality of Earnings analysis evaluates financial sustainability, but it does not provide a complete assessment of the overall quality of the business.

A company can have strong earnings quality but still face:

• Weak industry growth
• Technology disruption
• Regulatory risk
• Management challenges
• Competitive pressure

Similarly, a strategically attractive business may have financial reporting issues that require normalization.

QoE should therefore be evaluated alongside commercial, operational, legal, and strategic diligence.

Step 47: Evaluate the Sustainability of Revenue Growth

Buyers should understand whether recent revenue growth can reasonably continue.

Growth may be supported by:

• Recurring customer expansion
• New customer acquisition
• Pricing power
• Market growth
• Product expansion

Growth may be less sustainable when driven by:

• One-time projects
• Temporary shortages
• Unsustainable price increases
• Low-margin acquisitions
• Unusual customer purchases

Illustrative Revenue Growth Quality Analysis

Growth Source	Contribution
Existing Customer Growth	5%
New Customers	4%
Pricing	3%
One-Time Project	4%
Total Reported Growth	16%

If the one-time project is excluded, more sustainable underlying growth may be approximately 12%.

Step 48: Evaluate Margin Sustainability

EBITDA margins should also be examined for sustainability.

Margin expansion may result from legitimate operational improvements, but it can also reflect temporary conditions.

Potential temporary factors include:

• Unusually low labor costs
• Temporary supplier discounts
• Deferred hiring
• Reduced marketing
• Delayed maintenance

Illustrative Margin Normalization

Metric	Reported	Normalized
Revenue	$100M	$100M
EBITDA	$18M	$16.5M
EBITDA Margin	18.0%	16.5%

The difference may reflect costs that are expected to return after closing.

Step 49: Review Customer-Level Profitability

High revenue does not necessarily mean high-quality earnings if certain customers generate little or negative profit.

QoE analysis may evaluate profitability by customer.

Illustrative Customer Profitability

Customer	Revenue	Gross Margin
Customer A	$18M	15%
Customer B	$12M	42%
Customer C	$9M	48%

The largest customer generates the lowest margin, which may affect how the buyer evaluates customer concentration risk.

Step 50: Analyze Pricing Sustainability

Recent price increases can improve revenue and EBITDA, but buyers should determine whether those prices can be maintained.

Questions may include:

• Have customers accepted the increases?
• Has churn increased?
• Are competitors raising prices?
• Are contracts protecting pricing?
• Could prices decline as market conditions normalize?

A temporary pricing benefit may not deserve the same valuation treatment as recurring volume growth.

Step 51: Examine Unusual Period-End Activity

QoE professionals often review month-end, quarter-end, and year-end financial activity for unusual patterns.

Potential warning signs include:

• Large sales immediately before period-end
• Unusual journal entries
• Delayed expense recognition
• Unexpected credits after period-end
• Large manual adjustments

These patterns may indicate revenue cut-off issues or aggressive financial reporting.

Step 52: Review Post-Closing or Subsequent Events

Events occurring after the historical reporting period may provide important evidence regarding earnings quality.

Examples include:

• Customer cancellations
• Bad debt write-offs
• Supplier price increases
• New litigation
• Contract losses

Although these events may occur after the historical period, they can affect the buyer’s view of sustainable earnings.

Step 53: Evaluate Management Adjustments Consistently

Management may propose numerous EBITDA adjustments.

Buyers should apply a consistent framework to each one.

A useful test is whether the adjustment is:

• Clearly identifiable
• Measurable
• Supported by documentation
• Non-recurring
• Representative of future operations

Adjustments that fail these tests may not belong in normalized EBITDA.

Illustrative Adjustment Review Matrix

Adjustment	Seller Request	Buyer Accepted	Reason
One-Time Litigation	$0.8M	$0.8M	Documented and non-recurring
Future Hiring Savings	$1.0M	$0	Not yet implemented
Owner Compensation	$0.7M	$0.4M	Replacement cost required
Restructuring	$0.9M	$0.3M	Partially recurring

Step 54: Build a QoE Sensitivity Analysis

When certain adjustments remain uncertain, buyers can analyze valuation under multiple EBITDA scenarios.

Illustrative Sensitivity

EBITDA Scenario	EBITDA	Value at 9.0x
Seller Case	$21M	$189M
Base QoE Case	$19M	$171M
Conservative Case	$17M	$153M

This illustrates the transaction’s sensitivity to earnings-quality assumptions.

Step 55: Connect QoE with Purchase Price Negotiations

Quality of Earnings findings often become one of the central topics in purchase price discussions.

A buyer may use the analysis to support:

• A lower purchase price
• A revised valuation multiple
• A working capital adjustment
• An earnout
• A holdback or escrow

The appropriate response depends on the nature and permanence of the identified issue.

Step 56: Understand When the Multiple May Also Change

QoE findings can affect not only EBITDA but also the valuation multiple itself.

For example, the buyer may initially expect:

• Highly recurring revenue
• Low customer concentration
• Strong cash conversion

If diligence reveals the opposite, the buyer may conclude that the business deserves a lower valuation multiple in addition to lower normalized EBITDA.

Illustrative Double Impact

Scenario	EBITDA	Multiple	Enterprise Value
Initial Case	$20M	9.0x	$180M
Post-QoE Case	$18M	8.0x	$144M

The valuation declines because both sustainable earnings and perceived business quality have changed.

Step 57: Determine Whether an Issue Is Temporary or Structural

QoE findings should be classified based on whether they are temporary or structural.

Temporary Issues

• One-time legal expenses
• Short-term disruption
• Temporary implementation costs

Structural Issues

• Persistent customer churn
• Declining margins
• High ongoing CapEx
• Weak cash conversion
• Concentrated customer base

Structural issues may have a greater impact on valuation than temporary historical adjustments.

Step 58: Prepare for QoE Negotiation

Both buyers and sellers should be prepared to support their positions with documentation.

Useful evidence may include:

• Invoices
• Payroll records
• Customer contracts
• Legal documentation
• General ledger details
• Historical financial statements

Strong documentation can reduce disagreement and accelerate the transaction process.

Step 59: Keep QoE Analysis Independent from the Desired Deal Outcome

A common mistake is starting with a desired purchase price and then selecting adjustments that support that number.

A credible Quality of Earnings analysis should work in the opposite direction.

The process should first determine sustainable financial performance and then evaluate what that performance implies for valuation.

Common QoE Mistakes Buyers Should Avoid

• Accepting all seller add-backs
• Ignoring revenue normalization
• Focusing only on EBITDA
• Ignoring working capital
• Ignoring CapEx requirements
• Failing to test customer concentration
• Using pro forma savings as historical earnings
• Failing to update valuation after diligence

Common QoE Mistakes Sellers Should Avoid

• Using unsupported adjustments
• Calling recurring costs one-time
• Failing to reconcile financial information
• Ignoring cash flow issues
• Waiting for buyers to identify obvious problems
• Providing inconsistent financial data

Quality of Earnings Due Diligence Checklist

A comprehensive review may include:

• Reported EBITDA
• Normalized EBITDA
• EBITDA adjustment support
• Revenue by customer
• Recurring revenue
• Customer concentration
• Customer retention
• Gross margins
• Payroll
• Accounts receivable
• Inventory
• Accounts payable
• Working capital
• Capital expenditures
• Cash conversion
• Accounting policies
• Related-party transactions
• Debt-like items
• Management forecasts

Key Takeaway

Quality of Earnings analysis should ultimately provide a clear view of how sustainable the company’s revenue, margins, EBITDA, and cash flow really are. Buyers should evaluate not only individual accounting adjustments but also customer profitability, pricing sustainability, margin trends, working capital, capital requirements, and structural business risks. The most important QoE findings can affect both normalized EBITDA and the valuation multiple applied to those earnings. A disciplined analysis therefore connects financial diligence directly to purchase price, transaction structure, leverage, and investment returns.

Frequently Asked Questions About Quality of Earnings Analysis

1. What is a Quality of Earnings analysis?

A Quality of Earnings (QoE) analysis is a financial review designed to determine whether a company’s reported earnings reflect sustainable, recurring, and economically meaningful operating performance. It typically examines normalized EBITDA, revenue quality, customer concentration, working capital, cash conversion, capital expenditures, and accounting adjustments.

2. Why is Quality of Earnings important in M&A?

QoE analysis is important because many acquisitions are priced using EBITDA multiples. If reported EBITDA includes unsupported add-backs, non-recurring revenue, or temporarily reduced expenses, a buyer may overestimate sustainable earnings and overpay for the business.

3. What is normalized EBITDA?

Normalized EBITDA is an estimate of sustainable operating earnings after adjusting reported EBITDA for appropriate unusual, non-recurring, owner-related, or non-operating items.

4. Is Quality of Earnings the same as an audit?

No. An audit focuses primarily on whether financial statements are fairly presented under the applicable accounting framework. Quality of Earnings analysis is transaction-focused and evaluates whether reported earnings are sustainable and appropriate for valuation and investment decisions.

5. What is the difference between QoE and financial due diligence?

Quality of Earnings is often a major part of financial due diligence, but financial due diligence may also include working capital, debt-like items, cash flow, balance sheet analysis, capital expenditures, and financial forecast review.

6. What are common EBITDA add-backs?

Potential add-backs may include legitimate one-time legal expenses, transaction costs, excess owner compensation, and certain non-recurring restructuring costs. Each adjustment should be supported by evidence and assessed individually.

7. Are all one-time expenses valid EBITDA adjustments?

No. An expense should not automatically be added back simply because management labels it as one-time. If similar costs occur regularly or are required to operate the business, they may be recurring and therefore part of sustainable EBITDA.

8. Can Quality of Earnings reduce EBITDA?

Yes. QoE analysis can identify non-recurring revenue, understated payroll, recurring expenses that were excluded from adjusted EBITDA, or other items that reduce normalized earnings.

9. Why is revenue quality important?

Revenue quality helps determine how predictable future earnings may be. Recurring, diversified, and highly retained revenue may provide greater confidence than revenue dependent on one-time projects or a small number of customers.

10. How does customer concentration affect earnings quality?

High customer concentration increases the risk that losing a major relationship could materially affect future revenue and EBITDA. It may therefore influence both earnings-quality conclusions and valuation.

11. Why does cash conversion matter in QoE?

EBITDA does not equal cash flow. A company may report strong earnings while consuming substantial cash through working capital, capital expenditures, or other operating requirements. Poor cash conversion can indicate lower economic quality of earnings.

12. Why is working capital analyzed during QoE?

Working capital analysis helps determine how much operating capital the business normally requires. It may also identify deteriorating receivable collections, inventory buildup, supplier payment delays, or a potential purchase price adjustment at closing.

13. Why are capital expenditures important?

A company may report strong EBITDA while requiring significant ongoing capital investment. Maintenance CapEx is particularly important because it represents spending required to sustain the current level of operations.

14. What is a sell-side Quality of Earnings report?

A sell-side QoE report is prepared for the seller before or during a transaction process. It can help identify financial issues early, support normalized EBITDA, document working capital, and prepare management for buyer diligence.

15. What is buy-side Quality of Earnings?

A buy-side QoE analysis is prepared for the potential buyer or investor. It focuses on validating the seller’s reported financial performance, challenging adjustments, identifying financial risks, and determining sustainable earnings.

16. Can QoE findings change the purchase price?

Yes. If buyer-supported normalized EBITDA is lower than the seller’s figure, the buyer may seek a lower purchase price. QoE findings can also affect working capital adjustments, earnouts, financing, and transaction protections.

17. Can QoE affect the valuation multiple?

Yes. If diligence reveals weaker revenue quality, greater customer concentration, poor cash conversion, or other structural risks, the buyer may conclude that the business deserves a lower valuation multiple in addition to lower normalized EBITDA.

18. How does Quality of Earnings affect debt capacity?

Acquisition lenders frequently use EBITDA when determining leverage capacity. Lower QoE-supported EBITDA can therefore reduce the amount of debt available and increase the amount of equity required from the buyer.

Detailed Quality of Earnings Example

Consider a target company with the following reported financial performance:

• Revenue: $120 million
• Reported EBITDA: $20 million
• Seller Adjusted EBITDA: $23 million

The seller proposes several adjustments intended to demonstrate the company’s sustainable earnings capacity.

Seller EBITDA Bridge

Adjustment	Amount
Reported EBITDA	$20.0M
One-Time Legal Expenses	+$0.8M
Restructuring Costs	+$0.7M
Owner Compensation	+$0.5M
Future Cost Savings	+$1.0M
Seller Adjusted EBITDA	$23.0M

Buyer QoE Review

The buyer then performs a detailed Quality of Earnings analysis and reaches the following conclusions:

• The $0.8 million legal expense is genuinely non-recurring.
• Only $0.3 million of restructuring expenses are considered non-recurring.
• Only $0.3 million of owner compensation can be adjusted after accounting for replacement management costs.
• The $1 million of future savings has not yet been implemented and is excluded.
• A one-time customer project contributed $0.9 million to historical EBITDA and is removed.

Buyer-Supported QoE Bridge

Adjustment	Amount
Reported EBITDA	$20.0M
Valid Legal Expense Add-Back	+$0.8M
Accepted Restructuring Adjustment	+$0.3M
Owner Compensation Adjustment	+$0.3M
Remove One-Time Customer EBITDA	($0.9M)
Buyer-Supported Normalized EBITDA	$20.5M

Impact on Transaction Value

Assume the seller is seeking a valuation of 9.0x adjusted EBITDA.

Scenario	EBITDA	Value at 9.0x
Seller Case	$23.0M	$207.0M
Buyer QoE Case	$20.5M	$184.5M
Difference	$2.5M	$22.5M

The QoE findings create a potential valuation difference of $22.5 million.

Working Capital Finding

The buyer also determines that normalized working capital should be approximately $14 million.

Estimated working capital at closing is only $12 million.

This creates a potential additional adjustment of:

$14 million − $12 million = $2 million

Debt-Like Item Finding

Financial diligence identifies another $3 million of debt-like obligations.

These items may reduce Equity Value even if Enterprise Value remains unchanged.

Illustrative Transaction Bridge

Transaction Item	Amount
Buyer-Supported Enterprise Value	$184.5M
Less: Working Capital Shortfall	($2.0M)
Less: Debt-Like Items	($3.0M)
Indicative Adjusted Transaction Value	$179.5M

The combined financial diligence findings have materially changed the economics of the proposed transaction.

Final Quality of Earnings Analysis Framework

Stage	Primary Analysis

2. EBITDA Normalization	Test add-backs and non-recurring items
3. Revenue Quality	Recurring revenue, one-time revenue and recognition
4. Customer Analysis	Concentration, retention and profitability
5. Margin Analysis	Gross margins and expense sustainability
6. Working Capital	Receivables, inventory and payables
7. Cash Conversion	EBITDA compared with operating cash flow
8. Capital Expenditures	Maintenance and growth CapEx requirements
9. Accounting Review	Revenue recognition, capitalization and accruals
10. Debt-Like Items	Identify obligations affecting Equity Value
11. Forecast Review	Test management’s future assumptions
12. Transaction Impact	Valuation, financing and purchase price

Conclusion

Quality of Earnings analysis is one of the most important tools for understanding the true financial performance of a business before an acquisition, investment, financing, or sale.

The analysis goes far beyond simply calculating adjusted EBITDA.

A comprehensive QoE review examines:

• Revenue sustainability
• Customer retention
• Customer concentration
• EBITDA adjustments
• Gross margins
• Operating expenses
• Working capital
• Cash conversion
• Capital expenditures
• Accounting practices
• Debt-like obligations
• Management forecasts

These factors help determine whether reported earnings represent sustainable economic performance.

QoE Should Explain the Business Behind the Numbers

A high-quality QoE analysis does not simply identify accounting adjustments.

It explains why earnings changed, what drives revenue and margins, how much cash the company actually generates, and what financial requirements are necessary to sustain operations.

This gives buyers and investors a more complete understanding of the financial risks associated with the transaction.

Quality of Earnings and Valuation Are Closely Connected

When acquisition valuation is based on an EBITDA multiple, changes to normalized earnings can have a magnified impact on Enterprise Value.

QoE findings can also affect:

• The selected valuation multiple
• Debt capacity
• Sponsor equity requirements
• Working capital targets
• Transaction structure
• Investment returns

For this reason, Quality of Earnings analysis should be incorporated directly into valuation and transaction decision-making.
