Arguing EBITDA Adjustments: The Language of FDD

In Transaction Services, analysis without argument is incomplete. An EBITDA bridge is not just a list of numbers — it is a series of claims about the economic reality of a business. Each claim must be argued with evidence, logic and commercial reasoning. This is the language of FDD, and mastering it is what distinguishes senior practitioners from junior analysts.

The Anatomy of a Good EBITDA Argument

Every accepted or rejected EBITDA adjustment should be articulated in the same three-part structure:

1. Describe the item: What is it? Where does it appear in the P&L?
2. State the position: Is it accepted, rejected, or partially accepted? At what value?
3. Explain the rationale: Why? What evidence supports this position?

Example (Buy-Side)

Item: Restructuring costs of €420k in FY0

Position: Accepted as a non-recurring adjustment, +€420k to EBITDA

Rationale: The restructuring relates to a headcount reduction programme approved by the board in March FY0, affecting 15 roles. We have reviewed the board resolution (Data Room reference: F.3.2), the individual redundancy agreements, and the payroll records confirming that the affected roles are no longer active. No similar restructuring has occurred in FY-2 or FY-1. We are satisfied that this is a genuine one-off item unlikely to recur.

This structure — describe, position, evidence — works in a written FDD report, a management Q&A session, and a TS interview case study.

The Language of Acceptance

When accepting an adjustment, the language signals confidence and evidence:

• "We have reviewed [document] and are satisfied that..."
• "The item is supported by [evidence] and does not appear in prior years, indicating..."
• "Based on our analysis, we accept this adjustment in full / at a reduced amount of..."

The Language of Rejection

When rejecting a management add-back, the language must be direct but professional:

• "We are unable to accept this adjustment because..."
• "While we acknowledge management's view, the item appears in all three years of the analysis period, suggesting it is a recurring cost of operations."
• "The documentation provided does not sufficiently support the full quantum claimed."

Avoid hedging language that suggests uncertainty ("we might" or "it seems possible"). FDD arguments are factual or they are not made.

Arguing in the Management Q&A

The management Q&A is the oral equivalent of the written argument. Key principles:

• Prepare your position before the call. Know which items you accept, which you reject, and why.
• Ask evidence-seeking questions, not leading questions: "Can you walk me through the basis for this adjustment?" rather than "This is a one-off, correct?"
• Challenge respectfully but directly. "Thank you — that's helpful. However, I note this cost also appeared in FY-1. Can you explain the difference?"

Arguing in TS Interviews

In case study interviews, examiners deliberately include borderline adjustment items to test your reasoning:

• A restructuring cost that appeared twice in three years
• A management consulting fee that might be recurring
• A COVID-related cost that may straddle multiple periods

The strong candidate does not just classify the item — they explain the classification with evidence-based logic.

Conclusion

The language of EBITDA argumentation is a professional skill that develops with practice. The best TS analysts are those who can defend a position under challenge, with clarity and evidence, every time.
