Audit Report / Information • May 15, 2025

Dear Shareholder

CHANGE OF AUDITOR

As explained in the Annual Report and Financial Statement 2024 (the "Annual Report"), RM plc (the "Company", "RM") conducted a formal competitive and comprehensive external audit tender process during FY24, led by the Audit and Risk Committee (the "Committee"). Deloitte LLP informed the Company at the outset (July 2024) that they would not be participating in the tender, and four firms were shortlisted to take part. Following a rigorous review and scoring process, the Committee recommended to the Board the appointment of RSM UK Audit LLP as the Company's new external auditor, which was approved, and subsequently confirmed by shareholders at the AGM on 7 May 2025.

As part of the Audit and Risk Committee report (pages 98-103) in the Annual Report, I reported that during FY24 RM continued to evolve its control framework following the findings of previous years, with all of the recommendations made in the Financial Position and Prospects Procedures Report now having been materially addressed. Because the new controls had not operated for the whole of FY24 in the majority of cases, Deloitte LLP elected not to seek to test and place reliance on them and continued to undertake a substantive audit approach for the year ended 30 November 2024. During FY25, management have continued to ensure that controls are properly embedded through a programme of self-certification and testing by the Internal Audit & Internal Controls team, of which updates are reported back to the Audit and Risk Committee on a regular basis.

Yours faithfully,

Richard Smothers Non-executive director Audit and Risk Committee Chair

Dear Directors

Ceasing to act as auditors of RM plc registered number 01749877

This letter is formal notice that we will not be seeking reappointment as auditors of RM plc with effect from the conclusion of the forthcoming Annual General Meeting.

Yours faithfully

Statement of reasons relating to Deloitte LLP ceasing to act as auditors of RM plc

As communicated in the Annual report and financial statements of RM plc (the "Company") and its subsidiaries (the "Group") for the period ending 30 November 2024 ("Annual Report"), we are not seeking reappointment as auditors of the Company and, accordingly, will cease to hold office at the conclusion of the Annual General Meeting held on 7 May 2025.

As stated in the Annual Report on pages 102 (Audit and Risk Committee Report) and 132 (Independent Auditor's Report), while management have implemented control improvements during the year, most of these improvements are yet to be fully embedded and therefore deficiencies arose in their implementation. Although the directors do not disagree with the scope of our audit, the current control environment and information systems require additional audit effort to gain an appropriate level of assurance.

As set out in the CEO's statement on page 19 of the Annual Report, management have implemented a cost efficiency programme for the Group, including a review of their third-party advisors. We have chosen not to participate in the tender as the effort needed to audit the Group, when taking in to consideration the deficiencies in the control environment and its overall stage of maturity, is considerable and we did not expect to be able to propose a fee at a level below that paid in FY24.

Unless you apply to the Court, this statement must be sent by you within 14 days to every person entitled under Section 423 of the Companies Act 2006 to be sent copies of the company's accounts. This is a requirement of Section 520(2) of that Act. Unless you inform us that you have applied to the court, we are required to file a copy of this statement at Companies House.
