Notice of general meetings

1. That a general meeting of the Company, other than an annual general meeting, may be called on not less than 14 clear days' notice.

Recommendation

The Directors believe that each resolution being put to the meeting is in the best interests of the Company and its shareholders as a whole and unanimously recommend that shareholders vote in favour of all resolutions, as they intend to do in respect of their own beneficial shareholdings in the Company.

By order of the Board

Mark Jenkins

Company Secretary

12 June 2025

Registered office: Halma plc Misbourne Court, Rectory Way Amersham, Buckinghamshire HP7 0DE

Registered in England and Wales No. 40932

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 2025). 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 14.12p per share to shareholders for the financial year ended 31 March 2025, as recommended by the Directors. If approved, the dividend will be paid on 15 August 2025 to shareholders on the Register of Members at the close of business on 11 July 2025.

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 25 July 2025.

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 123 to 142 of the Annual Report and Accounts 2025. In accordance with the 2006 Act, the vote on this resolution is advisory and no remuneration is conditional on this resolution being passed.

Resolutions 4 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 appointment of Hudson La Force took place on 2 June 2025, and the appointment of Barbara Thoralfsson will, as previously announced, take effect on 16 June 2025. 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.

Committee Membership A Audit Committee N Nomination Committee R Remuneration Committee Chair of Committee Member of Committee

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 12 June 2025 (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 (i) the conclusion of the annual general meeting of the Company in 2026 and (ii) 30 September 2026. 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 12 June 2025 (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 12 June 2025 (being the latest practicable date prior to the publication of the Notice of Meeting).

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 2026 and (ii) 30 September 2026.

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 2024 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 2026 and (ii) 30 September 2026, in respect of up to 37,900,000 ordinary shares, which is approximately 10% of the Company's issued share capital as at 12 June 2025 (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 2024 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 2026, 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.

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 22 July 2025 (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

1. 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.
• 1. 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).
• 1. 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:
• a. electronically via the Registrar's website at www.investorcentre.co.uk/eproxy using the Control Number, Shareholder Reference Number (SRN) and PIN;
• b. 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
• c. 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 22 July 2025 (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).

• 1. 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.
• 1. 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 22 July 2025 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.

Nominated persons

1. Any person to whom this Notice of Meeting is sent who is a person nominated under Section 146 of the 2006 Act to enjoy information rights (a 'Nominated Person') may, under an agreement between him/her and the shareholder by whom he/she was nominated, have a right to be appointed (or to have someone else appointed) as a proxy for the AGM. If a Nominated Person has no such proxy appointment right or does not wish to exercise it, he/she may, under any such agreement, have a right to give instructions to the shareholder as to the exercise of voting rights.

The statement of rights of shareholders in relation to the appointment of proxies in paragraphs 3 to 8 does not apply to Nominated Persons. The rights described in these paragraphs can only be exercised by shareholders of the Company.

If you have been nominated to receive general shareholder communications directly from the Company, it is important to remember that your main contact in terms of your investment remains as it was (the registered shareholder, or perhaps custodian or broker, who administers the investment on your behalf). Therefore any changes or queries relating to your personal details and holding (including any administration thereof) must continue to be directed to your existing contact at your investment manager or custodian. The Company cannot guarantee that we will be able to deal with matters that are directed to us in error. The only exception to this is where the Company, in exercising one of its powers under the 2006 Act, writes to you directly for a response.

CREST electronic proxy appointment

• 1. CREST members who wish to appoint a proxy or proxies through the CREST electronic proxy appointment service may do so for the AGM and any adjournment of it by using the procedures described in the CREST Manual (available via www.euroclear.com). CREST personal members or other CREST sponsored members and those CREST members who have appointed a voting service provider should refer to their CREST sponsor or voting service provider, who will be able to take the appropriate action on their behalf.
• 1. In order for a proxy appointment or instruction made using the CREST service to be valid, the appropriate CREST message (a 'CREST Proxy Instruction') must be properly authenticated in accordance with Euroclear UK & International Limited's specifications and must contain the information required for such instructions, as described in the CREST Manual. The message, regardless of whether it constitutes the appointment of a proxy or is an amendment to the instruction given to a previously appointed proxy must, in order to be valid, be transmitted so as to be received by the Company's agent, Computershare Investor Services PLC (ID 3RA50), by the latest time(s) for receipt of

proxy appointments set out in paragraph 5. For this purpose, the time of receipt will be taken to be the time (as determined by the timestamp applied to the message by the CREST Applications Host) from which the Company's agent is able to retrieve the message by enquiry to CREST in the manner prescribed by CREST. After this time any change of instructions to proxies appointed through CREST should be communicated to the appointee through other means.

CREST members and, where applicable, their CREST sponsors or voting service providers, should note that Euroclear UK & International Limited does not make available special procedures in CREST for any particular messages. Normal system timings and limitations will therefore apply in relation to the input of CREST Proxy Instructions. It is the responsibility of the CREST member concerned to take (or, if the CREST member is a CREST personal member or sponsored member or has appointed a voting service provider, to procure that his /her CREST sponsor or voting service provider takes) such action as shall be necessary to ensure that a message is transmitted by means of the CREST system by any particular time. In this connection, CREST members (and, where applicable, their CREST sponsors or voting service providers) are referred, in particular, to those sections of the CREST Manual concerning practical limitations of the CREST system and timings.

The Company may treat as invalid a CREST Proxy Instruction in the circumstances set out in Regulation 35(5)(a) of the Uncertificated Securities Regulations 2001.

Corporate representatives

1. A corporation which is a shareholder can appoint one or more corporate representatives who may exercise, on its behalf, all of its powers as a shareholder provided that no two or more do so in relation to the same shares.

Audit concerns

• 1. Section 527 of the 2006 Act allows shareholders who meet the threshold requirements of that section to require the Company to publish a statement on its website setting out any matter relating to:
• a. the audit of the Company's accounts to be laid at the meeting (including the Auditor's Report and the conduct of the audit); or
• b. any circumstance connected with an Auditor of the Company ceasing to hold office since the previous meeting at which annual accounts and reports were laid in accordance with Section 437 of the 2006 Act.

The Company may require the shareholders requesting any such website publication to pay its expenses in complying with Sections 527 or 528 of the 2006 Act. Where the Company is required to place a statement on a website under Section 527 of the 2006 Act, it must forward the statement to the Company's Auditor not later than the time when it makes the statement available on the website. The business which may be dealt with at the AGM includes any statement that the Company has been required under Section 527 of the 2006 Act to publish on a website.

Shareholders' right to ask questions

1. Any shareholder attending the AGM has the right to ask questions. The Company must cause to be answered at the AGM any question relating to the business being dealt with at the AGM but no such answer need be given if:

(a) to do so would interfere unduly with the preparation for the AGM or involve the disclosure of confidential information; (b) the answer has already been given on a website in the form of an answer to a question; or (c) it is undesirable in the interests of the Company or the good order of the AGM that the question be answered.

In addition, shareholders are invited to submit questions regarding the formal business of the meeting by email to AGM@halma.com by 12.30pm on 22 July 2025. Shareholder questions will be grouped thematically and the responses made available on our website before the AGM.
