EXPLANATORY NOTES TO THE RESOLUTIONS PROPOSED AT THE ANNUAL GENERAL MEETING

All the Resolutions are proposed as ordinary resolutions. This means that for each of those Resolutions to be passed, more than half of the votes cast must be in favour of the Resolution. Voting on all Resolutions at the Annual General Meeting will be conducted by way of a poll, rather than a show of hands.

A “vote withheld” option will be provided to enable those voting to abstain on any Resolution. A vote withheld is not a vote in law and will not be counted in the calculation of the proportion of votes for and against a Resolution.

Resolution 1 – Annual Report and Accounts

The Directors are required by the Act to lay before the Company in general meeting copies of the directors’ reports, the independent auditors’ report and the audited financial statements of the Company in respect of each financial year. For the financial year ended 31 March 2025, these are all contained in the Annual Report and Accounts.

In accordance with best practice, the Company proposes an ordinary resolution to receive the Annual Report and Accounts, a copy of which may be found at: https://investors.arm.com/ir-resources/annual-meeting.

Resolution 2 – Approval of the Directors’ Remuneration Report

In accordance with section 439 of the Act, you are requested to approve the Directors’ Remuneration Report. The Directors’ Remuneration Report is set out on pages 45 to 56 of the Annual Report and Accounts.

The Board considers that appropriate remuneration of Directors plays a vital part in helping to achieve the Company’s overall objectives. We encourage you to read the Directors’ Remuneration Report. Our Board and the Remuneration Committee believe that the policies and procedures as articulated in the Directors’ Remuneration Report are effective and that, as a result of these policies and procedures, we have and will continue to have high-quality directors. Our UK statutory auditors, Deloitte LLP, have audited those parts of the Directors’ Remuneration Report that are required to be audited. The Board has approved and signed the report in accordance with the Act.

This vote is advisory and non-binding and the Directors’ entitlement to receive remuneration is not conditional on it. Payments made or promised to Directors will not have to be repaid, reduced or withheld in the event that the Resolution is not passed. Although non-binding, our Board and the Remuneration Committee will review and consider the voting results when making future decisions regarding our Directors’ remuneration.

Resolutions 3 and 4 – Appointment and remuneration of the auditors

The Company is required to appoint auditors at each general meeting at which accounts are laid before the members, to hold office until the conclusion of the next such meeting. Resolution 3 is an ordinary resolution to re-appoint Deloitte LLP as the Company’s auditors to hold office until the conclusion of the next annual general meeting at which accounts are laid. They have indicated their willingness to stand for reappointment as auditors of the Company until the conclusion of the annual general meeting in 2026. The Audit Committee keeps under review the independence and objectivity of the external auditors. After considering the relevant information, the Audit Committee has recommended to the Board that Deloitte LLP be re-appointed as auditors. The Audit Committee will continue to consider the reappointment of the external auditors each year before making a recommendation to the Board.

Resolution 4 is an ordinary resolution to authorise the Audit Committee to determine the auditors’ remuneration. In accordance with the charter of the Audit Committee, the Board has delegated authority to the Audit Committee to determine the auditors’ remuneration.

Resolutions 5 to 12 (inclusive) – Re-appointment of Directors

4

The Articles require that, at the end of each annual general meeting of the Company, all of the directors of the Company holding office at the date that notice is sent of that annual general meeting shall retire from office, except for any director appointed by the directors of the Company after notice of that annual general meeting has been given and before that annual general meeting has been held. Each of the Directors listed below is retiring and seeks re-election at the Annual General Meeting. Resolutions 5 to 12 seek your approval to re-elect these persons as directors of the Company.

Having considered the performance of and contribution made by each of these Directors, the Board remains satisfied that, and the Chairman confirms that, the performance of each of these Directors continues to be effective and to demonstrate commitment to the role and as such the Board recommends their re-election. Biographical information for all the Directors standing for re-election is set out below.
