EBITDA Adjustments in Financial Due Diligence: Overview
A structured overview of EBITDA adjustments in FDD: what they are, why they matter, and how analysts categorise them in QoE reports.
EBITDA adjustments sit at the heart of every Financial Due Diligence (FDD) engagement. They transform a company's reported earnings into a figure that genuinely reflects the underlying economic performance of the business — and they directly influence the acquisition price paid by a buyer.
What Are EBITDA Adjustments?
An EBITDA adjustment is any modification made to the reported EBITDA of a business to arrive at a "normalised" or "adjusted" EBITDA. The goal is to strip out items that distort the true recurring profitability of the company.
In a Transaction Services context, adjustments are presented in a Quality of Earnings (QoE) report and are subject to scrutiny from both the buyer's and seller's advisers. The final agreed figure feeds directly into the valuation multiple applied at deal close.
The Main Categories of Adjustments
Non-Recurring Items
These are one-off costs or revenues that are unlikely to repeat in future periods. Classic examples include:
- Legal settlements and litigation costs
- Costs related to a one-time restructuring programme
- Losses or gains on asset disposals
- COVID-19-related support income (e.g. government grants)
The key test is whether a reasonable buyer would expect the item to recur. If not, it is typically adjusted out of EBITDA.
Run-Rate Adjustments
Run-rate adjustments account for structural changes to the business that occurred mid-period. If a company hired 20 additional sales staff in October of the reporting year, the full-year cost impact is not yet visible in the historical P&L. A run-rate adjustment annualises that cost.
Similarly, if a business opened a new facility in Q3, the revenue from that facility for the full year should be reflected in the adjusted EBITDA.
Pro Forma Adjustments
Pro forma adjustments reflect changes that will happen post-closing or that relate to acquired/disposed businesses. Examples include:
- Annualisation of a bolt-on acquisition completed during the year
- Removal of revenues and costs from a divested business unit
- Synergy adjustments (treated with caution by FDD advisers)
Management Adjustments vs. Adviser Adjustments
In every deal, management presents its own version of adjusted EBITDA, often with optimistic add-backs. The FDD team's role is to critically review these, challenge unsupported items, and arrive at a supportable adjusted EBITDA. The difference between management's figure and the adviser's figure is always a key discussion point.
Why EBITDA Adjustments Matter in M&A
- Valuation impact: If the deal is priced at 8x EBITDA, a €500k adjustment changes the enterprise value by €4 million.
- Negotiation leverage: Buyers use challenged adjustments to push back on price; sellers use accepted add-backs to justify a higher valuation.
- Warranty and indemnity: Agreed adjusted EBITDA often forms the basis for earn-out calculations and completion mechanisms.
Common Pitfalls for Junior Analysts
- Accepting management's description at face value without checking the supporting documentation
- Failing to assess whether a "one-off" has actually recurred in prior years
- Ignoring the interaction between an adjustment and working capital (e.g. a provision release affects both EBITDA and NWC)
Conclusion
Mastering EBITDA adjustments is non-negotiable for anyone entering Transaction Services. The ability to identify, quantify and argue each adjustment — both orally in interviews and in writing in QoE reports — sets strong candidates apart from average ones.
