Quality of Earnings Audit | M&A Due Diligence
Earnings Clarity Built for Valuation, Negotiation, and Close
Wahl Street Accountancy Corporation delivers decision-grade Quality of Earnings (QoE) and M&A due diligence that surfaces real earnings power, quantifies risk, and supports confident valuation before capital is committed. Built for buyers, sellers, and advisors operating under tight timelines and high scrutiny.
Turning Financial Statements Into Transaction Intelligence
In acquisitions, capital raises, and exits, the question is never whether a company has earnings; it’s whether those earnings are durable, repeatable, and transferable to the next owner. A quality of earnings audit answers that question by translating reported results into transaction-ready insight.
Wahl Street Accountancy Corporation provides transaction-focused quality of earnings due diligence and M&A diligence consulting for buyers, sellers, and advisors operating in complex, time-sensitive deal environments. Our work is designed to surface the real earnings power of a business, quantify risk, and support confident valuation decisions before capital is committed.
The Scope of a Quality of Earnings Review
A quality of earning audit helps you look past reported EBITDA to understand how your business truly generates cash and whether those earnings will hold up after the transaction. At Wahl Street, our QoE engagements are designed to give buyers and sellers clear, defensible insight they can rely on throughout M&A due diligence.
Our work typically includes:
Revenue Quality Analysis
We identify non-recurring or unsustainable revenue, customer concentration risk, pricing volatility, and revenue recognition issues.
Normalized EBITDA and Cash Flow
We adjust for owner compensation, related-party activity, discretionary expenses, and timing distortions to arrive at sustainable earnings.
Expense Sustainability Review
We assess whether the current cost structure is realistic under new ownership, including deferred expenses or suppressed SG&A.
Working Capital Dynamics
We evaluate seasonality, historical trends, and normalized working capital targets that affect purchase price mechanics.
Accounting Policy and Risk Assessment
We identify aggressive accounting positions, GAAP gaps, and issues that may lead to buyer pushback or post-close adjustments during M&A due diligence.
Buy-Side vs. Sell-Side QoE
While the underlying analysis is similar, the value of a quality of earnings audit depends heavily on whether you are buying or selling and understanding that difference gives you a clear advantage at the negotiating table.
Buy-Side QoE
A buy-side quality of earnings audit helps you confirm what you are actually buying by testing earnings sustainability and identifying financial risks before close. It supports valuation decisions, deal structure, and downside protection during M&A due diligence.
- Sustainable EBITDA and cash flow analysis
- Identification of non-recurring or overstated revenue
- Expense normalization and cost structure review
- Customer concentration and margin stability analysis
- Working capital trends and normalized targets
- Accounting risks affecting valuation or deal terms
Sell-Side QoE
A sell-side quality of earnings audit helps you define and defend your earnings narrative before buyers begin diligence. It improves credibility, reduces uncertainty, and supports stronger valuation outcomes throughout M&A due diligence consulting.
- Normalized EBITDA with supportable adjustments
- Explanation of one-time or non-recurring items
- Revenue durability and customer concentration review
- Identification of potential buyer concerns
- Support for working capital targets
- Preparation for buyer diligence discussions
Key Adjustments That Impact Valuation
In most transactions, valuation is driven by a multiple of EBITDA or cash flow, meaning even small adjustments identified through a quality of earnings audit can materially impact purchase price. Wahl Street’s role is not to inflate earnings, but to apply disciplined judgment, defending adjustments that hold up under scrutiny and removing those that introduce risk or undermine credibility.
Common adjustments that often have the greatest impact on valuation include:
When to Start QoE in a Transaction
Timing is one of the most underestimated drivers of transaction outcomes. When a quality of earnings audit is started early, it creates leverage. When it’s delayed, it becomes damage control.
Sell-Side Transactions
Best timing: 3–6 months before going to market
Early QoE gives sellers time to fix accounting issues, support adjustments, and eliminate weak add-backs before buyers see them. Starting late forces explanations under pressure and undermines credibility during diligence.
Buy-Side Transactions
Best timing: Immediately after LOI (earlier for proprietary deals)
Delaying QoE compresses diligence timelines, reduces leverage, and increases execution risk. Early analysis gives buyers clarity on earnings quality before price, structure, and momentum are locked in.
Capital Raises & Recapitalizations
Best timing: Before institutional capital is engaged
Investors will run their own diligence. A prepared QoE shifts the conversation from defending numbers to aligning on valuation, structure, and growth.
