Explanatory notes to the proxy form

• 1. Shareholders have the right to appoint a proxy of his or her choice, who need not be a shareholder but must attend the meeting in person to represent you, to exercise all or any of his or her rights, to vote and submit questions on their behalf at the meeting. Due to the continuing potential health risks from public gatherings because of the COVID-19 pandemic, shareholders are encouraged to appoint the Chairman of the General Meeting as their proxy and to give their instructions on how they wish the Chairman of the General Meeting to vote on the Resolutions on their behalf. If you wish to appoint a person other than the Chairman of the General Meeting, please insert the name of your chosen proxy holder in the space provided. If you wish to appoint the Chairman of the General Meeting as your proxy, please leave the "name of proxy" box blank. If the proxy is being appointed in relation to less than your full voting entitlement, please enter in the box below the proxy holder's name the number of shares in relation to which they are authorised to act as your proxy. If this box is left blank, your proxy will be deemed to be authorised in respect of your full voting entitlement (or if this proxy form has been issued in respect of a designated account for a shareholder, the full voting entitlement for that designated account).
• 1. To appoint more than one proxy, (an) additional proxy form(s) may be obtained by contacting the Registrar's UK helpline on 0333 207 5963 or the overseas helpline on +44 333 207 5963 or you may photocopy this form. Please indicate in the box below the proxy holder's name the number of shares in relation to which they are authorised to act as your proxy. Please also indicate, by ticking the box provided, if the proxy instruction is one of multiple instructions being given. All proxy forms must be signed and should be returned together in the same envelope. Please note that if multiple proxies are appointed, each proxy may only be appointed to exercise the rights attached to a different share or shares held by the appointing shareholder.
• 1. Full details of the resolutions to be proposed at the General Meeting, with explanatory notes, are set out in the Notice of General Meeting. Before completing this proxy form, please also read the section entitled "Action to be Taken" in the Circular. You can access the Circular and the Notice of General Meeting at www.smiths.com.
• 1. You may instruct your proxy how to vote by marking the appropriate box next to each resolution. Details of the resolutions are contained in the Notice of General Meeting and the explanatory notes. If you have not given specific instructions on how your proxy should vote in respect of any resolution, your proxy will have discretion to vote on that resolution, in respect of your total holding, as they see fit. Your proxy will also have discretion to vote as they see fit on any other business which may properly come before the meeting, including amendments to resolutions, and at any adjournment of the meeting.
• 1. The 'Vote withheld' boxes are provided to enable you to withhold your vote on any particular resolution. You should note, however, that a 'Vote withheld' is not a vote in law and will not be counted in determining the proportion of votes cast 'For' and 'Against' a resolution.

Paper proxy forms must be received at Equiniti Limited, Aspect House, Spencer Road, Lancing, West Sussex BN99 6DA, not later than 48 hours before the General Meeting to be effective (i.e. before 11.00am on 15 September 2021). If the proxy form is signed by someone else on your behalf, his or her authority to sign must be returned with the proxy form. In the case of a corporation, the appointment of a proxy must be executed either under its common seal or by

a duly authorised officer or agent. In the case of joint holders, any holder may sign. The vote of a more senior joint holder on the register of members will be accepted to the exclusion of a junior joint holder. For this purpose, the order in which the names of the joint holders are recorded in the register of members will determine seniority.
