# Underlying Profit Before Tax

Underlying profit before tax is statutory profit before tax adjusted to remove items management regards as unrepresentative of ongoing performance, such as restructuring costs, conduct charges, acquisition-related amortisation and one-off gains. It is an alternative performance measure: the company chooses the definition, and its usefulness depends on what is excluded and why.

**Also known as:** Underlying PBT, Adjusted profit before tax, Adjusted PBT

## Key facts

- **Used at:** headline results of UK-listed companies, banks and specialist lenders among them (Shawbrook, for one, leads its results with it), and in management reporting, bonus targets and loan covenants
- **Binding:** not defined by accounting standards; ESMA's guidelines on alternative performance measures, applying to EU issuers' regulated information and prospectuses since 3 July 2016, require a definition, a reconciliation to the nearest line in the financial statements, comparatives, and no more prominence than the statutory figures
- **Coming change:** IFRS 18, effective for periods beginning on or after 1 January 2027, requires companies to disclose management-defined performance measures used in public communications in their financial statements
- **Typical adjustments:** restructuring and integration costs, amortisation of acquired intangibles, fair-value unwinds on acquired loan books, litigation and redress provisions, gains or losses on disposals, listing and transaction costs
- **Parties:** the finance team and board that define it, the auditors, analysts and investors who read it, and in a sale the buyer's financial due diligence team

## How underlying profit before tax works in practice

Statutory profit before tax records everything that happened in the year; underlying profit is management's argument about what will happen again. Sometimes the argument is sound. A bank that buys a loan book at a discount books fair-value unwinds for years, and stripping them out shows how the lending itself performs. Sometimes it is convenient. Restructuring charges that appear every year are an operating cost, and ESMA's guidelines make the point directly: items that affected past periods and will affect future ones, restructuring and impairment among them, will rarely be non-recurring.

The practitioner's check is the reconciliation. Read every adjusting item over three to five years; look for items that recur under new labels, gains left in while losses are taken out, and costs moved between lines. Compare underlying growth with statutory growth; a widening gap is a finding in itself.

For a buyer, underlying profit before tax is the seller's first draft of maintainable earnings. Financial due diligence rebuilds it in the quality-of-earnings work, accepting some adjustments, rejecting others and adding its own. A price set as a multiple of earnings moves with every adjustment the buyer rejects, and any earn-out, covenant or incentive that refers to underlying profit needs its definition fixed in the contract, not left to next year's annual report.

## Example

A UK specialist lender reports statutory profit before tax of £84m and underlying profit before tax of £112m. The £28m of adjustments: £11m of integration costs from a broker acquisition, £7m of amortisation on acquired intangibles, £6m for a customer-redress provision and £4m of costs for a planned listing. A buyer's diligence team accepts the amortisation and listing costs, questions the integration costs — the lender has reported them in each of the last four years — and treats the redress provision as recurring because a similar charge appeared two years earlier. Its view of maintainable pre-tax profit is £95m. After 25% tax and at eight times earnings, the gap between the seller's figure and the buyer's is worth about £100m of equity value.

## Common mistakes

- Accepting adjustments because they are labelled one-off, without checking whether they recur.
- Comparing underlying profit across companies that define it differently.
- Excluding the losses while keeping the gains.
- Forgetting that restructuring and redress are paid in cash, whatever the underlying figure says.
- Writing "underlying profit" into an earn-out or covenant without fixing its definition at signing.
