Normalising earnings
Why earnings shown in annual accounts are adjusted before being used in a valuation, and what kinds of items are typically added back or removed.

Normalising earnings means adjusting the results reported in a company's annual accounts to remove one-off or non-recurring items, so that the figure used in a valuation reflects the company's ongoing earning capacity. This applies to both cost and income items that are unlikely to repeat or that do not reflect market-standard conditions.
- Normalisation adjusts reported earnings to reflect recurring, ongoing performance.
- One-off costs, exceptional income and non-market terms are typical adjustments.
- Every adjustment should be documented and traceable to the accounts.
Reported earnings are not always representative
The profit and loss account of a given year can include items that are unlikely to recur, such as a one-off restructuring cost, an insurance settlement, or a gain from selling an asset unrelated to the company's core activity. Using such a year's earnings without adjustment would overstate or understate the company's ongoing capacity to generate results.
Normalisation is the process of identifying these items and adjusting the earnings figure so that it better reflects what the company can be expected to generate in a typical year, rather than the specific circumstances of one period.
Common categories of adjustment
Non-recurring costs, such as legal disputes, relocation expenses, or costs tied to a specific project that has since ended, are commonly added back. Similarly, income from a one-off event, such as a subsidy received for a single year or a gain on the disposal of an asset, is typically removed from the base used for the valuation.
Adjustments can also relate to items that recur but are not set at market terms, which is addressed separately when it involves matters such as director remuneration or related-party transactions affecting the reported result.
Adjustments require supporting evidence
An adjustment is only as reliable as the evidence behind it. A cost described as exceptional should be traceable to a specific event in the accounts or supporting documentation, rather than asserted without a clear basis. This is part of why a valuation professional will typically request explanations for unusual variations between years.
Ter illustratie, a company that recorded a legal settlement cost in one year, clearly identifiable in the notes to the accounts, might see that cost added back for the purpose of establishing a normalised earnings base, while the remaining years are left unadjusted.
Normalisation affects both the formula's shortcomings and the valuation report
The statutory formula uses EBITDA exactly as reported, without any normalisation. This is one of its structural limitations, since a company whose reported earnings were affected by a one-off item in the relevant year will see that distortion carried directly into the formula's result.
An independent valuation report, by contrast, is expected to examine the composition of reported earnings and adjust for items that would otherwise misrepresent the company's ongoing performance, before applying any valuation method.
Documenting the reasoning behind each adjustment
A defensible valuation report sets out each normalisation adjustment individually, with the reasoning and the source in the accounts, rather than presenting only a final adjusted figure. This transparency allows a reader, including a tax administration, to trace how the reported figures were used and why.
Questions on this
Does normalisation always increase the earnings figure
No. Normalisation can move the figure in either direction, depending on whether the one-off items identified were costs or income. The purpose is accuracy, not a higher or lower result by default.
Is normalisation applied to the statutory formula
No. The statutory formula uses EBITDA as reported in the annual accounts, without adjustment. Normalisation is a feature of an independent valuation report, not of the formula.
What evidence supports a normalisation adjustment
Adjustments should be traceable to specific items in the accounts or supporting documentation, such as notes describing a one-off cost or income item, rather than general statements about a company's typical performance.
