Explanatory Notes:

• 1. As explained in the Notice of AGM, we strongly encourage shareholders not to attend the AGM in person. Shareholders can instead attend and participate in the AGM virtually via a live webcast, where they will be able to vote electronically and ask questions. Details of how to attend virtually can be found on page 12 of the Notice of AGM which can be viewed and downloaded from the Company's website at: https://www.halma.com/investors/shareholderinformation/agm-information. You will need the Meeting ID 104-632-620 and your unique SRN and PIN set out above to attend virtually.
• 2. Every holder has the right to appoint some other person(s) of their choice, who need not be a shareholder, as their proxy to exercise all or any of their rights, to attend, speak and vote on their behalf at the meeting. Shareholders are strongly encouraged to appoint the Chair of the meeting as their proxy, particularly if you do not propose to attend the AGM electronically. The appointment of any person other than the Chair of the meeting may result in your votes not being cast, as third-party proxies may not be permitted to attend the AGM, subject to the Government restrictions then in place. If you still wish to appoint a person other than the Chair, please insert the name of your chosen proxy holder in the space provided (see reverse). If the proxy is being appointed in relation to less than your full voting entitlement, please enter in the box next to the proxy holder's name (see reverse) the number of shares in relation to which they are authorised to act as your proxy. If returned without an indication as to how the proxy shall vote on any particular matter, the proxy will exercise their discretion as to whether, and if so how, they vote.
• 3. The 'Vote Withheld' option overleaf is provided to enable you to abstain on any particular resolution. However, it should be noted that a 'Vote Withheld' is not a vote in law and will not be counted in the calculation of the proportion of the votes 'For' and 'Against' a resolution.

Kindly Note: This form is issued only to the addressee(s) and is specific to the unique designated account printed hereon. This personalised form is not transferable between different: (i) account holders; or (ii) uniquely designated accounts.

• 5. Pursuant to Regulation 41 of the Uncertificated Securities Regulations 2001, entitlement to attend and vote at the meeting and the number of votes which may be cast thereat will be determined by reference to the Register of Members of the Company at close of business on the day which is two days before the day of the meeting. Changes to entries on the Register of Members after that time shall be disregarded in determining the rights of any person to attend and vote at the meeting.
• 6. To give an instruction to a proxy (whether previously appointed or otherwise) via a designated voting platform, any such messages must be received by the issuer's agent prior to the specified deadline within the relevant system. For this purpose, the time of receipt will be taken to be the time (as determined by the timestamp generated by the relevant designated voting platform) from which the issuer's agent is able to retrieve the message. The Company may treat as invalid a proxy appointment sent via a designated voting platform in the circumstances set out in Regulation 35(5)(a) of the Uncertificated Securities Regulations 2001.
