Quality of Earnings Report
A QoE report is like a forensic deep-dive into a company's earnings during a PE deal. It answers: 'Is the EBITDA the seller claims actually real, recurring, and sustainable?'
Definition
A Quality of Earnings (QoE) report is a detailed financial analysis performed during due diligence — typically by an accounting firm hired by the buyer — that validates the target company's reported earnings and adjusted EBITDA. The QoE goes beyond a standard audit to assess whether the company's earnings are sustainable, recurring, and accurately stated. It is one of the most critical workstreams in any PE acquisition because the purchase price is based on a multiple of earnings.
Common QoE Adjustments
Normalizing earnings to reflect true economic reality
Owner Compensation
Above-market salary normalization
One-Time Legal Costs
Non-recurring lawsuit settlement
Related-Party Revenue
Revenue from owner's other entity
Deferred Maintenance
CapEx classified as maintenance

Purpose and Scope of a QoE
The primary purpose of a QoE is to determine whether the seller's reported or adjusted EBITDA accurately reflects the company's ongoing earnings power. The report examines revenue quality (is it recurring or one-time?), expense normalization (are costs being understated?), working capital trends, and customer concentration risk. A QoE also identifies the appropriate level of normalized working capital, which becomes the 'peg' or target for the working capital adjustment in the purchase agreement.
Common QoE Adjustments
QoE analysts scrutinize every add-back and adjustment the seller makes to arrive at adjusted EBITDA. Common adjustments include removing one-time legal settlements, normalizing owner compensation to market rates, adding back non-recurring consulting or transaction costs, and adjusting for revenue timing differences. Importantly, the QoE often identifies adjustments the seller did not make — such as above-market related-party transactions or aggressive revenue recognition policies — which reduce the true EBITDA figure.
Red Flags in a QoE Analysis
Several patterns signal earnings quality concerns: a widening gap between EBITDA and operating cash flow, aggressive revenue recognition (booking revenue before delivery), heavy reliance on add-backs that exceed 25-30% of reported EBITDA, customer concentration where one client represents more than 20% of revenue, and declining gross margins masked by cost-cutting. A QoE that reveals materially lower EBITDA than the seller represented often leads to purchase price renegotiation or deal termination.
Impact on Deal Terms and Valuation
The QoE directly influences the final purchase price because the deal is typically structured as a multiple of trailing EBITDA. If the QoE reduces adjusted EBITDA by $2M and the deal multiple is 8x, the implied purchase price drops by $16M — illustrating the leverage of enterprise value multiples. The QoE also establishes the normalized working capital target used in the purchase agreement's closing mechanism. Sellers increasingly commission their own sell-side QoE before going to market to preempt buyer adjustments and maintain negotiating leverage.
Worked Example — With Real Numbers
A PE firm is acquiring a company with seller-reported Adjusted EBITDA of $25M at an 8x multiple ($200M EV). The buyer's QoE report finds: (1) $1.5M of revenue was pulled forward from the next quarter, (2) the owner's salary is $500K below market rate, and (3) $1M of claimed one-time legal costs are actually recurring compliance expenses. QoE-adjusted EBITDA = $25M - $1.5M - $0.5M - $1M = $22M. At 8x, the implied EV drops from $200M to $176M — a $24M reduction that the buyer uses to renegotiate the price.
Key Takeaways
QoE reports validate whether a seller's claimed EBITDA is real, recurring, and sustainable
The QoE is the most important financial due diligence workstream in a PE acquisition
Common adjustments include normalizing owner compensation, removing one-time items, and correcting revenue timing
QoE findings directly impact the purchase price (EBITDA x multiple) and working capital peg
Sell-side QoE reports are increasingly common as sellers try to preempt buyer adjustments
Common Mistakes in Interviews
Confusing a QoE with a financial audit — audits verify GAAP compliance, while QoE assesses earnings sustainability and quality
Assuming every seller add-back is legitimate — QoE analysts frequently reject or reduce seller-proposed adjustments
Forgetting that QoE also establishes the working capital peg, not just EBITDA — this affects closing cash flow
Not understanding that a QoE reduction has a multiplied impact on valuation (e.g., $1M EBITDA reduction at 10x = $10M lower EV)
How Interviewers Test This
If asked about due diligence or how PE firms validate earnings, reference the QoE directly: 'The buyer commissions a Quality of Earnings report to verify adjusted EBITDA by testing revenue sustainability, expense normalization, and working capital trends.' Then give an example of an adjustment — like normalizing below-market owner compensation — to show you understand the practical mechanics.
