• a) to allotments in connection with rights issues and other pre-emptive issues but subject to such exclusions or other arrangements as the Directors may deem necessary or expedient in relation to treasury shares, fractional entitlements, record dates or legal, regulatory or practical problems in, or under the laws of, any territory or any other matter;

such authority to expire (unless previously renewed, varied or revoked by the Company in general meeting) at the end of the next Annual General Meeting of the Company or, if earlier, the close of business on 31 January 2025 but, in each case, so that the Company may, before such expiry, make offers, and enter into agreements, which would, or might, require equity securities to be allotted (and treasury shares to be sold) after the authority expires and the Directors may allot equity securities (and sell treasury shares) under any such offer or agreement as if the authority had not expired.

For the purposes of this Resolution:

a) 'rights issue' means an offer to:

• i. ordinary shareholders in proportion (as nearly as may be practicable) to their existing holdings; and
• ii. people who are holders of other equity securities if this is required by the rights of those securities or, if the Directors consider it necessary, as permitted by the rights of those securities to subscribe for further securities by means of the issue of a renounceable letter (or other negotiable document) which may be traded for a period before payment for the securities is due,

• a) the allotment of equity securities or sale of treasury shares (otherwise than pursuant to paragraph (b)) up to an aggregate nominal amount of £13,032,687, provided that the allotment is for the purposes of financing (or refinancing, if the authority is to be used within 12 months after the original transaction) a transaction which the Directors determine to be an acquisition or specified capital investment of a kind contemplated by the Statement of Principles on Disapplying Pre-Emption Rights most recently published by the Pre-Emption Group prior to the date of this notice; and
• b) when any allotment of equity securities or sale of treasury shares is or has been made pursuant to paragraph (a) (a 'paragraph (a) allotment'), the allotment of additional equity securities or sale of additional treasury shares up to an aggregate amount equal to 20% of the aggregate amount of that paragraph (a) allotment, provided that any allotment pursuant to this paragraph (b) is for the purposes of making a follow-on offer determined by the Directors to be of a kind contemplated by paragraph 3 of section 2B of the Statement of Principles on Disapplying Pre-Emption Rights most recently published by the Pre-Emption Group prior to the date of this notice,

such authority to expire (unless previously renewed, varied or revoked by the Company in general meeting) at the end of the next Annual General Meeting of the Company or, if earlier, at the close of business on 31 January 2025, but, in each case, so the Company may, before such expiry, make offers and enter into agreements during the relevant period which would, or might, require equity securities to be allotted (or treasury shares to be sold) after the authority expires and the Directors may allot equity securities (or sell treasury shares) under any such offer or agreement as if the authority had not expired.

That the Company be and is hereby unconditionally and generally authorised for the purpose of Section 701 of the Companies Act 2006 (the 'Act') to make market purchases (as defined in Section 693 of the Act) of ordinary shares of 37.5p each in the capital of the Company on such terms and in such manner as the Directors may determine provided that:
• a) the maximum number of ordinary shares which may be purchased is 34,753,833;
• b) the minimum price (exclusive of expenses) which may be paid for each share is 37.5p;

Registered office: 4th floor, 11-12 St James's Square London SW1Y 4LB Registered in England and Wales no. 00137013

THE NOTES ON THE FOLLOWING PAGES PROVIDE AN EXPLANATION OF THE PROPOSED RESOLUTIONS

Resolutions 1 to 16 and 21 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.

Resolutions 17 to 20 (inclusive) are proposed as special resolutions. This means that for each of those resolutions to be passed, at least three-quarters of the votes cast must be in favour of the resolution.

RECOMMENDATION

Your Directors believe that all the proposals to be considered at the Annual General Meeting (the 'AGM') are in the best interests of the Company and its shareholders as a whole, and recommend shareholders to vote in favour of the resolutions. The Directors intend to vote in favour of the resolutions in respect of their own beneficial holdings.

RESOLUTION 1: RECEIPT OF REPORTS AND ACCOUNTS

The Directors must present the reports of the Directors and the accounts of the Company for the year ended 31 July 2023 to shareholders at the AGM. The reports of the Directors (including the Strategic Report), the accounts, and the report of the Company's auditors on the accounts and on those parts of the Directors' Remuneration Report that are required to be audited are contained within the FY2023 Annual Report.

RESOLUTION 2: APPROVAL OF DIRECTORS' REMUNERATION REPORT

Under Section 420 of the Companies Act 2006 (the 'Act'), the Directors must prepare a remuneration report detailing the remuneration of the Directors and containing a statement by the Chair of the Remuneration & People Committee. The Act also requires that a resolution be put to shareholders each year for their approval of that report. This is an advisory resolution only.

RESOLUTION 3: DECLARATION OF FINAL DIVIDEND

A final dividend can only be paid after shareholders have approved it at a general meeting. If the final dividend is approved, it will be payable on 24 November 2023 to shareholders on the register of members at 6.00pm on 20 October 2023 (the record date).

From November 2019, Smiths Group plc stopped issuing dividend cheques. In order for shareholders to have dividends paid directly to their bank or building society account they should contact the Company's registrar, Equiniti, for a copy of the Bank Mandate Form.

RESOLUTIONS 4 TO 13: ELECTION AND RE-ELECTION OF DIRECTORS

As previously announced, Sir George Buckley will retire from the Board at the conclusion of the AGM and will therefore not stand for re-election. Steve Williams, having been appointed to the Board since the last AGM will, in accordance with the Company's Articles of Association, retire and stand for election at the AGM. Subject to Steve Williams' election by shareholders, he will become Chair of the Smiths Group plc Board upon Sir George Buckley's retirement.

The Chairman confirms, on behalf of the Board, that each Director standing for election or re-election continues to be effective and demonstrates commitment to their respective roles.

See the appendix to the Notes on pages 10 and 11 for detailed biographies of the Directors. Their biographies are also available on pages 80 and 81 of the FY2023 Annual Report and the Company's website, www.smiths.com. The Nomination & Governance Committee Report on page 87 of the FY2023 Annual Report provides further information in support of the Director re-elections.

RESOLUTIONS 14 AND 15: REAPPOINTMENT AND REMUNERATION OF KPMG LLP AS AUDITOR

The Board, on the advice of the Audit & Risk Committee (summarised in the Audit & Risk Committee Report on pages 95 and 96 of the FY2023 Annual Report), recommends the reappointment of KPMG LLP as auditor, to hold office until the next meeting before which the accounts are laid (Resolution 14).

Resolution 15 authorises the Audit & Risk Committee, acting for and on behalf of the Board, to determine the remuneration of KPMG LLP for their services as auditor.

RESOLUTION 16: AUTHORITY TO ALLOT SHARES

The purpose of Resolution 16 (the 'allotment resolution') is to renew the Directors' power to issue and allot new shares in the Company.

The authority in Resolution 16 will allow the Directors to allot new shares in the Company or to grant rights to subscribe for or convert any security into shares in the Company up to a nominal value of £43,442,291, which is equivalent to approximately one third of the nominal amount of the ordinary share capital of the Company in issue on 2 October 2023.

As at 2 October 2023, the Company did not hold any treasury shares.

If the resolution is passed the authority will expire on the earlier of the close of business on 31 January 2025 and the end of the AGM due to be held in 2024, unless previously renewed, varied or revoked.

The Directors have no current intention to use this authority, but it is sought to ensure the Directors maintain maximum flexibility in response to capital management.

RESOLUTIONS 17 AND 18: DISAPPLICATION OF PRE-EMPTION RIGHTS

If the Directors wish to allot new shares and other equity securities, or sell treasury shares, for cash (other than in connection with an employee share scheme), company law requires that these shares are offered first to the shareholders, in proportion to their existing holdings.

The Directors consider it desirable to have the flexibility permitted by corporate governance guidelines to respond to market developments and to enable allotments to take place to finance business opportunities without making a pre-emptive offer to existing shareholders.

This cannot be done under the Act unless shareholders have first waived their pre-emption rights. The purpose of Resolutions 17 and 18 (together the 'disapplication of pre-emption rights resolutions') is to enable shareholders to waive their pre-emption rights.

Resolution 17 authorises Directors to allot new shares, pursuant to the authority given by Resolution 16 (the 'allotment resolution'), or to sell treasury shares for cash:

• a) in connection with a rights issue or other pre-emptive issue to allow the Directors to make appropriate exclusions and other arrangements to resolve legal or practical problems which, for example, might arise in relation to overseas shareholders;
• b) otherwise up to a nominal value of £13,032,687, equivalent to approximately 10% of the total issued ordinary share capital of the Company as at 2 October 2023; and/or
• c) for the purposes of a follow-on offer (such follow-on offer determined by the Directors to be of a kind contemplated by the Pre-Emption Group's 2022 Statement of Principles) when an allotment of shares has been made under paragraph (b), up to a nominal amount equal to 20% of the nominal value of any shares allotted under paragraph (b),

in each case without the shares first being offered to existing shareholders in proportion to their existing holdings.

Resolution 18 additionally authorises the Directors to allot new shares, pursuant to the authority given by Resolution 16, or to sell treasury shares for cash, without the shares first being offered to existing shareholders in proportion to their existing holdings.

The authority in Resolution 18 is limited to the allotment of shares or sale of treasury shares for cash:

• a) up to a nominal amount of £13,032,687 which represents approximately a further 10% of the Company's issued ordinary share capital (excluding treasury shares) as at 2 October 2023, which may only be used for an allotment of shares for cash for the purposes of financing (or refinancing, if the waiver is used within twelve months of the original transaction) a transaction which the Directors determine to be an acquisition or specified capital investment of a kind contemplated by the Pre-emption Group's 2022 Statement of Principles;
• b) for the purposes of a follow-on offer (such follow-on offer must be determined by the Directors to be of a kind contemplated by the Pre-Emption Group's 2022 Statement of Principles) when an allotment of shares has been made under paragraph (a), up to a nominal amount equal to 20% of the nominal value of any shares allotted under paragraph (a).

The allotment and the disapplication of pre-emption rights resolutions are within the guidance set out in The Investment Association's Share Capital Management Guidelines issued in February 2023 and the Pre-emption Principles. The Directors intend to follow the shareholder protections contained in section 2B and the expected features of a follow-on offer in paragraph 3 of section 2B of the Pre-Emption Group's 2022 Statement of Principles.

If the resolutions are passed, the authorities and waivers will expire on the earlier of the close of business on 31 January 2025 and the end of the AGM due to be held in 2024, unless previously renewed, varied or revoked.

As at 2 October 2023, the Company did not hold any treasury shares. If the Company were to create treasury shares, e.g. through the market purchase of its own shares, the subsequent sale of any treasury shares (or the use of treasury shares to satisfy obligations under the Company's share schemes and plans) would be counted as equivalent to the issue of new shares for the purpose of the limitations on the issue of new shares included in the allotment resolution and disapplication of pre-emption rights resolutions.

RESOLUTION 19: PURCHASE OF OWN SHARES

The effect of this resolution is to grant authority to the Company to purchase its own ordinary shares, up to a maximum of 34,753,833 ordinary shares. The authority shall expire (unless previously renewed, varied or revoked by the Company in general meeting) at the end of the next Annual General Meeting of the Company, or, if earlier, at the close of business on 31 January 2025. This represents approximately 10% of the number of ordinary shares in issue as at 2 October 2023 and the Company's exercise of this authority is subject to the stated upper and lower limits on the price payable, which reflect the requirements of the FCA's Listing Rules.

Although the Directors do not currently have any intention of exercising the authority granted by this resolution, this resolution provides the flexibility to allow them to do so in the future. In considering whether to use this authority, the Directors will take into account market conditions, appropriate gearing levels, the Company's share price, other investment opportunities and the overall financial position of the Company. The Directors will only exercise the authority to purchase ordinary shares where they consider that such purchases will be in the best interests of shareholders generally and will result in an increase in earnings per share.

Any shares purchased in the market under this authority may be either cancelled or held as treasury shares, which may then be cancelled, sold for cash or used to satisfy obligations under the Company's employee share schemes. The Company's current intention is to cancel any repurchased shares but retains the flexibility to hold any repurchased shares as treasury shares, if it considers this to be in the best interests of the Company. No dividends are paid on shares while they are in treasury and no voting rights attach to treasury shares.

As at 2 October 2023, there were 4,835,145 outstanding options and awards, granted under all share schemes operated by the Company, which, if vested, would represent 1.37% of the issued ordinary share capital of the Company. If the authorities to purchase the Company's own shares (both existing and sought) were exercised in full, that percentage would increase to 1.52%. With regard to the authorities sought under Resolutions 16 to 19, the Directors' intention would be to exercise the authorities given to them by the resolutions in accordance with the Share Capital Management Guidelines issued by The Investment Association in February 2023.

RESOLUTION 20: NOTICE OF GENERAL MEETINGS

Under the Act, the Company may call a general meeting, other than an AGM, by giving 14 clear days' notice to shareholders. Under the Companies (Shareholders' Rights) Regulations 2009 this period is extended to 21 clear days unless the Company has obtained shareholder approval for a shorter period. This resolution would maintain the current position as agreed by shareholders at the 2022 AGM. The shorter notice period would not be used as a matter of routine but only where the flexibility was merited by the business of the meeting and was thought to be in the interests of shareholders as a whole. AGMs will still require at least 21 clear days' notice.

RESOLUTION 21: POLITICAL DONATIONS

Part 14 of the Act requires companies to obtain shareholders' authority for donations to political parties or other political organisations or an independent election candidate in the UK totalling more than £5,000 in any twelve month period, and for any political expenditure in the UK, subject to limited exceptions. The definition of donation in this context is very wide and extends to bodies such as those concerned with policy review, law reform and the representation of the business community. It could include special interest groups, such as those involved with the environment, which the Company and its UK subsidiaries might wish to support, even though these activities are not designed to support or influence support for a particular political party.

It is the policy of the Company not to make political donations or incur political expenditure in the UK as those expressions are normally understood. However, to avoid inadvertent infringement of the Act, the Directors are seeking shareholders' authority for the Company and its UK subsidiaries (by virtue of the Act, the term 'subsidiary' in Resolution 21 is a reference to each UK subsidiary of the Company) to make political donations and to incur political expenditure in the UK up to a maximum aggregate amount of £50,000 for the period from the date of the Annual General Meeting to the end of the next Annual General Meeting of the Company, or, if earlier, at the close of business on 31 January 2025.

Any shareholders wishing to vote on the day of the AGM will need to attend the AGM in person or by proxy. A proxy need not be a shareholder of the Company. A proxy form which may be used to make such appointment and give proxy instructions accompanies this notice. If you do not have a proxy form and believe that you should have one, or if you require additional forms, please contact Equiniti Limited on +44 (0)371 384 2943.

The on-screen instructions will give details on how to complete the appointment and voting process. To be effective, electronic proxy appointments and voting instructions must be received before 11.00am on 14 November 2023 (or, in the event of an adjournment, not later than 48 hours before the time of the adjourned meeting).

1. The return of a completed proxy form, other such instrument, any CREST Proxy Instruction (as described in paragraph 10 below) or the appointment of a proxy electronically will not prevent a shareholder attending the AGM and voting in person at the AGM if he or she wishes to do so.

2. 1. Any person to whom this notice is sent who is a person nominated under Section 146 of the Act to enjoy information rights (a 'Nominated Person') may, under an agreement between him/her and the shareholder by whom he or she was nominated, have a right to be appointed (or to have someone else appointed) as a proxy of that shareholder for the AGM. If a Nominated Person has no such proxy appointment right or does not wish to exercise it, he or she may, under any such agreement, have a right to give instructions to the shareholder as to the exercise of voting rights.
3. 1. The statement of the rights of shareholders in relation to the appointment of proxies in paragraph 3 above does not apply to Nominated Persons. The rights described in that paragraph 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 the registered shareholder or 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) must continue to be directed to your existing contact at your investment manager or custodian.

The Company cannot guarantee to deal with matters that are directed to them in error. The only exception to this is where the Company, in exercising one of its powers under the Act, writes to you directly for a response.

1. In order to be entitled to vote at the AGM or any adjourned meeting (and for the purpose of the determination by the Company of the votes they may cast), shareholders must be registered in the register of members of the Company at 6.30pm on 14 November 2023 (or, in the event of any adjournment, 6.30pm on the date which is two days before the time of the reconvening of the adjourned meeting).

2. 1. CREST members who wish to appoint a proxy or proxies through the CREST electronic proxy appointment service may do so 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 service provider(s), should refer to their CREST sponsor or voting service provider(s), who will be able to take the appropriate action on their behalf.
3. 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's specifications, and must contain the information required for such instruction, as described in the CREST Manual (available via www.euroclear.com). 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 (CREST Participant ID: RA19) by the latest time(s) for receipt of proxy appointments specified in the notice of meeting (being 11.00am on 14 November 2023). For this purpose, the time of receipt will be taken to be the time (as determined by the time stamp applied to the message by the CREST Application 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.
4. 1. CREST members (and, where applicable, their CREST sponsors, or voting service providers) should note that Euroclear does not make available special procedures in CREST for any particular message. 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 CREST sponsor or voting service provider(s) take(s)) 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 system providers) are referred, in particular, to those sections of the CREST Manual concerning practical limitations of the CREST system and timings.
