What are one-off costs and how do you recognise them?

Non-recurring costs are expenses that are not part of normal business operations and occur only once. In business valuation, these costs are filtered out to show a company's true earning power. Correctly identifying one-off costs is crucial for accurate valuation in mergers and acquisitions, as they affect the enterprise value and final sale price.

What exactly are one-off costs and why are they important?

Non-recurring costs are expenses that are not part of the normal, recurring operations of a company. These costs arise from specific events or decisions and are not expected to recur in the future.

The distinction between structural and incidental costs forms the basis of business valuation. Structural costs recur every year and determine operational profitability. Incidental costs distort this picture and need to be filtered out to determine true earning power.

In M&A transactions, correct identification is essential as buyers want to assess future profitability. One-off costs distort operational performance and can lead to undervaluation of the company.

How do you recognise one-off costs in the income statement?

Non-recurring costs are identifiable by their exceptional nature and the fact that they do not arise from normal business activities. They are often disclosed under separate items or explained in the financial statements.

Common categories are:

  • Reorganisation costs and severance payments
  • Legal fees for disputes or transactions
  • Amortisation of goodwill or impairment losses
  • Costs for IT implementations or system migrations
  • Consulting fees for mergers and acquisitions

Practical landmarks are the size (often significantly higher than normal costs), the timing (sudden occurrence) and the notes in the financial statements highlighting the exceptional nature.

Why are one-off costs filtered out in EBITDA normalisation?

EBITDA normalisation filters out one-off costs to reveal a company's underlying operational performance. This process shows the ‘real’ earning power without distortion from incidental events.

The normalisation process works as follows: reported EBITDA is increased by one-off costs to arrive at a normalised EBITDA arrive at. These adjusted figures form the basis for valuation multiples and future cash flow projections.

For buyers, normalised EBITDA is crucial as they assess what the company can structurally earn. Without normalisation, one-off costs would lead to a lower valuation, while these costs do not occur in the future.

Which one-off costs are most common among Dutch companies?

Dutch companies have specific patterns in one-off costs, often related to business transitions, digitalisation and regulation. Restructuring costs top the list due to reorganisations and efficiency programmes.

The most common types are:

  • Restructuring costs in reorganisations
  • IT implementation costs for ERP systems
  • Legal costs for litigation or compliance
  • Management-buy-out-related costs
  • Business relocation costs
  • Consultancy fees for strategic decisions

Points of recognition are the direct relationship to a specific event, the one-off nature and the deviation from normal cost patterns. These costs are often explained separately in management reports.

How do one-off costs affect enterprise value in a sale?

One-off costs have a direct impact on enterprise value as they affect the basis for valuation multiples. Correct identification can significantly increase valuation by showing higher structural profitability.

In negotiations, discussions often arise between buyers and sellers about which costs are really one-offs. Buyers are cautious and want proof that costs are not recurring. Sellers want to classify as many costs as possible as one-offs to increase valuation.

The impact on the final sale price depends on the valuation multiple used. With an EBITDA multiple of 6x, each euro of normalised EBITDA leads to six euros of higher enterprise value. Professional sales guidance helps position normalisations optimally.

What are the pitfalls in determining one-off costs?

The biggest pitfall is sellers interpreting one-off costs too broadly and buyers judging them too strictly. This leads to protracted discussions and can threaten deal security.

Common mistakes are:

  • Presenting structural costs as one-offs
  • Insufficient documentation of exceptionalism
  • Failure to distinguish between the timing and character of costs
  • Underestimating the impact of due diligence on normalisations

Preparation is crucial: document all normalisations with clear substantiation and anticipate critical questions from buyers. A thorough analysis prevents surprises during due diligence and strengthens the negotiating position.

Correctly identifying and handling non-recurring costs requires in-depth expertise in business valuation and M&A processes. For optimal results in complex standardisation issues, it is advisable to seek timely professional advice through contact with experienced corporate finance specialists.
