NOTES ON THE RESOLUTIONS

Resolutions 1 to 18 will be proposed as ordinary resolutions which require a simple majority of the votes to be cast in favour of each resolution to be passed. Resolutions 19 to 22 will be proposed as special resolutions which require at least 75% of the votes to be cast in favour of each resolution to be passed.

Resolution 1 - Annual Report and Accounts

The Directors are required by the 2006 Act to present the audited accounts of the Company to shareholders at a general meeting, together with reports of the Directors (including the Strategic Report) and the Auditor (in this case for the year ended 31 March 2024). As a matter of best practice, these are put to shareholders for approval.

Resolution 2 - Final Dividend

This resolution seeks authority for the Company to pay a final dividend of 13.20p per share to shareholders for the financial year ended 31 March 2024, as recommended by the Directors. If approved, the dividend will be paid on 16 August 2024 to shareholders on the Register of Members at the close of business on 12 July 2024.

The Company offers a Dividend Reinvestment Plan ('DRIP') to enable shareholders to elect to have their cash dividends reinvested in Halma plc shares. Shareholders who wish

to opt for the DRIP for the forthcoming final dividend, but have not already done so, should return a DRIP mandate form to the Company's Registrar no later than 26 July 2024.

Resolution 3 - Remuneration Report

Section 439 of the 2006 Act requires that the Remuneration Report is put to a vote of shareholders at each general meeting at which accounts of the Company are presented. The Remuneration Report is set out on pages 152 to 157 and 166 to 177 of the Annual Report and Accounts 2024.

In accordance with the 2006 Act, the vote on this resolution is advisory and no remuneration is conditional on this resolution being passed.

Resolution 4 - Remuneration Policy

The purpose of resolution 4, which is proposed as an ordinary resolution, is to invite shareholders to approve the Directors' Remuneration Policy (the 'Policy'). The vote on the Policy is a binding vote. If resolution 4 is passed, the Policy shall take effect immediately after the end of the AGM (the 'Effective Date'), meaning that from the Effective Date the Company may not make a remuneration payment or a payment for loss of office to a person who is, is to be, or has been a Director of the Company unless the payment is consistent with the Policy, or has been otherwise approved by shareholder resolution. If the Policy is not approved for any reason, the Company will, if and to the extent permitted by the 2006 Act, continue to make payments to Directors in accordance with the existing Policy and will seek shareholder approval for a further revised Policy as soon as is practicable.

If approved by shareholders, the Policy will be subject to a binding shareholder vote by ordinary resolution in a further three years (in accordance with the 2006 Act), except in the event that a change to the Policy is proposed or the advisory vote on the Remuneration Report is not passed in any year subsequent to the approval of the Policy.

As described in the Remuneration Report, the Remuneration Committee discussed the details of the Policy over a series of meetings, to assess whether the 2021 remuneration policy remains appropriate and relevant in the context

of the Company's strategic plan and business goals set against a changing macro economic environment.

With support from internal experts and external advisers, the Remuneration Committee concluded that the 2021 remuneration policy remains appropriate, so the overall structure remains unchanged from that policy. Only minor editorial amendments have been made for administrative reasons. The Policy is set out on pages 158 to 165 of the Annual Report and Accounts 2024.

Resolutions 5 to 14 - Election and Re-Election of Directors

The Company's Articles of Association require, and the UK Corporate Governance Code recommends, that each Director retire at the Annual General Meeting and seek re-election.

All of the Directors seeking re-election have been subject to a performance evaluation. Based on that evaluation, it is considered that each Director continues to be effective and demonstrates the level of commitment required in connection with their role and the needs of the business. The Board, on the recommendation of the Nomination Committee, supports the election and re-election of each of the Directors.

It is the Board's view that each Director's contribution is, and continues to be, important to the Company's long-term sustainable success, as described in each Director's biography set out below.

NOTES ON THE RESOLUTIONS continued

Resolution 15 - Re-appointment of Auditor

The Company is required under the 2006 Act to appoint an auditor at every general meeting at which accounts are presented, to hold office until the conclusion of the next general meeting at which accounts are presented. The Directors are proposing the reappointment of PricewaterhouseCoopers LLP as the Company's Auditor. The proposal to re-appoint PricewaterhouseCoopers LLP as the Company's Auditor is based on a recommendation from the Audit Committee, is free from third party influence and is not subject to any restrictive contractual arrangements.

Resolution 16 - Auditor's remuneration

In accordance with standard practice, this resolution gives authority to the Directors, acting through the Audit Committee, to determine the Auditor's remuneration for the next financial year.

Resolution 17 - Authority to allot shares

The purpose of this resolution is to renew the Directors' authority to allot shares. This resolution would allow the Directors to allot shares and grant rights to subscribe for or convert any securities into shares up to an aggregate nominal value of £12,500,000, being just less than one third of the total issued share capital of the Company (excluding treasury shares) as at 13 June 2024 (being the latest practicable date prior to the publication of the Notice of Meeting). The Company currently does not hold any shares in treasury.

In accordance with the Directors' stated intention to seek annual renewal, the authority will expire on the earlier of

1. the conclusion of the annual general meeting of the Company in 2025 and (ii) 30 September 2025. Passing this resolution will give the Directors flexibility to act in the best interests of shareholders, when opportunities arise. The Directors have no current plans to make use of this authority.

Resolution 18 - Political Donations and expenditure Under the 2006 Act, political donations exceeding £5,000 in aggregate in any 12 month period to any political parties, independent election candidates or political organisations or the incurring of political expenditure are prohibited unless authorised by shareholders in advance. The Company does not, directly or through any subsidiary, make political donations or incur political expenditure within the ordinary meaning of those words and the Directors have no intention of using the authority for that purpose. The authority being requested from shareholders is not designed to change this. However, the definitions used in the 2006 Act are very broad and, as a result, it is possible that normal business activities (commonly accepted as a way of engaging with stakeholders to ensure that issues and concerns which are important to the Company are addressed) may be caught by the legislation. Activities of this nature are not designed to support any political party or to influence public support for a particular party. This resolution is proposed to ensure that the Company and its subsidiaries do not, because of any uncertainty due

to the broad nature of the definitions under the 2006 Act, unintentionally commit any technical breach of the 2006 Act.

Resolutions 19 and 20 - Disapplication of pre-emption rights

Resolutions 19 and 20, which will be proposed as special resolutions, would give the Directors the power to allot shares (or sell treasury shares) for cash, without first offering them to existing shareholders in proportion to their current holdings.

The power in resolution 19 would be limited (i) to allotments or sales under resolution 17 in connection with pre-emptive offers; or (ii) otherwise to allotments or sales up to an aggregate nominal amount of £1,890,000 (representing 18,900,000 ordinary shares of 10 pence each), which represents approximately 5% of the Company's issued share capital as at 13 June 2024 (being the latest practicable date prior to the publication of the Notice of Meeting).

The effect of resolution 20 is to empower the Directors to disapply statutory pre-emption rights in respect of an additional £1,890,000 (representing 18,900,000 ordinary shares of 10 pence each), which represents approximately 5% of the Company's issued share capital as at

13 June 2024 (being the latest practicable date prior to the publication of the Notice of Meeting).

08    Halma plc | Notice of Annual General Meeting 2024

In accordance with the Pre-Emption Group's Principles, the Directors confirm that the power under resolution 20 will be used only in connection with an acquisition or specified capital investment that is announced contemporaneously with the issue, or that has taken place in the preceding 12-month period and is disclosed in the announcement of the issue.

The Directors are aware of the Pre-Emption Group's most recent Statement of Principles on Disapplying Pre-emption Rights published in November 2022. However, at this time, the Directors consider it appropriate to retain the previous limits of 5% of the issued ordinary share capital of the Company in resolutions 19 and 20 and have not adopted the increased limits. The Directors will keep emerging market practice under review.

The powers in resolution 19 and resolution 20 will expire on the earlier of (i) the conclusion of the annual general meeting of the Company in 2025 and (ii) 30 September 2025.

The Director's confirm that they intend to follow the shareholder protections in paragraph one of Part 2B of the Statement of Principles on Disapplying Pre-Emption Rights, published by the Pre-Emption Group.

The Directors have no current plans to make use of these powers.

Resolution 21 - Authority to purchase own shares The Directors were authorised at the 2023 annual general meeting of the Company to purchase up to 37,900,000 of the Company's own 10p ordinary shares in the market. In accordance with the Directors' stated intention to seek annual renewal, this resolution (which will be proposed as a special resolution) will renew this authority until the earlier of (i) the conclusion of the annual general meeting of the Company in 2025 and (ii) 30 September 2025,

in respect of up to 37,900,000 ordinary shares, which is approximately 10% of the Company's issued share capital as at 13 June 2024 (being the latest practicable date prior to the publication of the Notice of Meeting).

The Directors have no present intention of exercising the authority to make market purchases. However, the Directors consider it desirable that the possibility of making such purchases, under appropriate circumstances, is available. The Directors will only make purchases under the authority where they believe that to do so would result in an increase in earnings per share for the remaining shareholders or where the purchased shares are to be used to satisfy awards made under employee share plans, and such purchases are considered to be in the best interests of shareholders generally.

Any shares purchased under the authority would be either held as treasury shares or cancelled. The Company does not currently hold any shares in treasury or have any outstanding options or warrants.

Resolution 22 - Notice of general meetings

Under the 2006 Act, the notice period for general meetings is 21 clear days' notice unless shareholders approve a shorter notice period, which cannot be less than 14 clear days. Annual general meetings must be held on at least 21 clear days' notice.

Resolution 22 seeks to renew the authority obtained at the 2023 annual general meeting of the Company allowing the Company to call general meetings (other than annual general meetings) on not less than 14 clear days' notice.

It is intended that a shorter notice period will not be used as a matter of routine for general meetings, but only if the flexibility would be helpful given the business of the meeting and where the Board thinks it is in the interest of shareholders as a whole. If the resolution is passed, the authority will be effective until the annual general meeting of the Company in 2025, when it is intended that a similar resolution will be proposed.

The Company offers the facility for shareholders to vote and appoint proxies by electronic means. This is accessible to all shareholders and would be available if the Company were to call a meeting on 14 clear days' notice.

INFORMATION FOR SHAREHOLDERS

Entitlement to attend and vote

1. Entitlement to attend, speak and vote at the annual general meeting ('AGM') and the number of votes which may be cast at the AGM, will be determined by reference to the Register of Members of the Company at close of business on 23 July 2024 (or, in the event of any adjournment of the AGM, close of business on the date which is two days before the time of the adjourned meeting, provided that no account shall be taken of any part of a day that is not a working day). Changes to entries on the Register of Members after the relevant deadline shall be disregarded for the purpose of determining the rights of any person

to attend and vote at the relevant meeting.

Voting procedures

2. In line with best practice, all resolutions at the AGM will be taken on a poll vote. On a poll, each shareholder has one vote for every share held. The Directors believe a poll is more representative of shareholders' voting intentions because shareholders' votes are counted according to the number of shares held and all votes tendered are taken into account whether or not a shareholder is able to attend and vote in person. The results of voting at the AGM will be published on our website at www.halma.com and will be released via the London Stock Exchange plc as soon as possible following the AGM.

Appointment of proxies

1. A shareholder entitled to attend and vote at the AGM is entitled to appoint a proxy or proxies to exercise all or any of a shareholder's rights at the AGM. A proxy does not need to be a shareholder of the Company. The return of a completed Proxy Form, other such instrument or any CREST Proxy Instruction (as described in paragraph 11) will not prevent a shareholder from attending the AGM and voting
   in person if he/she wishes to do so.
2. A Proxy Form which may be used to make such appointment and give proxy instructions has been sent to all shareholders (except those who have elected to receive notice via email, who are able to appoint a proxy or proxies as described in paragraph 5).

5. In order to be valid, an appointment of a proxy or proxies must be completed, and returned, together with the power of attorney or other authority (if any) under which it is signed, or a duly certified copy of such authority, by one of the following methods:

1. electronically via the Registrar's website at www.investorcentre.co.uk/eproxy using the Control Number, Shareholder Reference Number (SRN) and PIN;
2. in hard copy form by post, courier or by hand, to the Company's Registrar, Computershare Investor Services PLC at The Pavilions, Bridgwater Road, Bristol, BS99 6ZY; or
3. in the case of CREST members, by using the CREST electronic proxy appointment service (as set out in paragraph 11);

in each case so that it is received no later than 12.30pm on 23 July 2024 (or, in the event of any adjournment of the AGM, not less than 48 hours before the time fixed for the adjourned meeting, provided that no account shall be taken of any part of a day that is not a working day).

6. In the case of a joint holding, a proxy or proxies need only be signed by one joint holder. If more than one such joint holder completes a proxy appointment, the appointment submitted by the most senior holder shall be accepted to the exclusion of the votes of the other joint holders. Seniority is determined by the order in which the names appear in the Register of Members.

1. If two or more valid but differing appointments of a proxy are received in respect of the same share for use at the same AGM, the appointment of the proxy which is last received before the latest time for the receipt of proxies (regardless of its date or the date of its signature) shall be treated as replacing the others as regards that share. If the Company is unable to determine which was last received, none of them shall be treated as valid in respect of that share.
2. Proxymity Voting - if you are an institutional investor you may also be able to appoint a proxy electronically via the Proxymity platform, a process which has been agreed by the Company and approved by the Company's Registrar. For further information regarding Proxymity, please go to www.proxymity.io. Your proxy must be lodged by 12.30pm on 23 July 2024 in order to be considered valid (or, in the event of any adjournment of the AGM, not less than 48 hours before the time fixed for the adjourned meeting, provided that no account shall be taken of any part of a day that is not a working day). Before you can appoint a proxy via this process you will need to have agreed to Proxymity's associated terms and conditions. It is important that you read these carefully as you will be bound by them and they will govern the electronic appointment of your proxy.
