Dear Shareholder

On 29 January 2024 we announced that, following the completion of a competitive tender process, the Board of Directors would be appointing PricewaterhouseCoopers LLP ("PwC") as the Group's independent auditor for the financial period ending 30 September 2024. The reappointment of PwC as independent auditor for the financial year ending 30 September 2025 will be subject to approval by the Group's shareholders at the next Annual General Meeting.

The Group's Audit Committee decided to undertake a formal audit tender process following the end of the FY23 financial period, which represents the most recent yearly set of financial statements audited by KPMG LLP ("KPMG"). The appointment of PwC follows a recommendation to the Board by the Audit Committee, following the completion of this formal tender process.

As a result, KPMG has resigned from its role as auditor of the Group with effect from 15 January 2024. As required by Section 519 of the Companies Act 2006, KPMG has deposited a statement with the Group that confirms there are no circumstances in connection with its resignation as auditor that should be brought to the attention of members or creditors of NCC Group plc. In accordance with section 520(2) of the Companies Act 2006, we are notifying you of such statement, which is enclosed.

If you have sold or otherwise transferred your shares in NCC Group plc, please forward this document to the stockbroker, bank or other agent through which the sale or transfer was effected, for transmission to the purchaser or transferee.

Yours sincerely,

Jonathan Williams Company Secretary
