Dear Shareholder

Notice of Annual General Meeting

I have pleasure in inviting you to the Annual General Meeting (the 'AGM') of IMI plc (the 'Company'), which will be held at the Crowne Plaza Hotel, Pendigo Way, Marston Green, Birmingham on 4 May 2023 commencing at 10am (a map can be found on page 10). The formal Notice of Meeting is set out on pages 2 to 5 of this circular followed by explanatory notes on pages 6 to 9.

As at the date of this letter, we are planning to hold an "in person" AGM and shareholders are welcome to attend. Any changes to the AGM arrangements will be published on our website (www.imiplc.com) and announced through the London Stock Exchange. I would ask that shareholders continue to monitor the website for any announcements and updates.

Voting

Whether or not you propose to attend the AGM, I would encourage you to vote on each of the resolutions set out in the notice of AGM by appointing a proxy to act on your behalf and by giving your voting instructions. I would strongly encourage you to appoint the Chair of the meeting as your proxy. This will ensure that your vote will be counted if ultimately you are (or any other proxy you might otherwise choose to appoint is) not able to attend the AGM for any reason. If you appoint the Chair of the meeting as your proxy, the Chair will vote in accordance with your instructions. If the Chair is given discretion as to how to vote, he or she will vote in favour of each of the resolutions in the notice. Appointing a proxy will not prevent you from attending and voting in person on the day if you wish to do so. As in previous years and in line with best practice, voting will be on a poll. The Board believes that voting on a poll will result in the most accurate reflection of the views of shareholders by ensuring that every vote is recognised, including all proxy votes. On a poll, each shareholder has one vote for every share held.

Recommendation

The directors consider that all the resolutions to be put to the AGM are in the best interests of the Company and are most likely to promote the success of the Company for the benefit of its shareholders as a whole. The directors unanimously recommend shareholders to vote in favour of the resolutions as they intend to do in respect of their own shareholdings (except in respect of those matters in which they are interested).

Yours faithfully

Lord Smith of Kelvin

Chair

• 8. CREST members who wish to appoint a proxy or proxies through the CREST electronic proxy appointment service may do so for the AGM to be held on 4 May 2023 and any adjournment(s) thereof by using the procedure described in the CREST manual. CREST personal members or other CREST sponsored members, and those CREST members who have appointed a voting 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.

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 & Ireland's specifications and must contain the information required for such instructions as described in the CREST manual (available at www.euroclear.com). The message, regardless of whether it constitutes the appointment of a proxy or relates to 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 issuer's agent (ID RA19) by the latest time(s) for receipt for proxy appointments specified in the Notice of AGM. 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 Application Host) from which the issuer'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 & Ireland does not make available special procedures in CREST for any particular messages. Normal system timings and limitations will 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(s), to procure

that his/her 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 sponsor(s) or voting service provider(s) 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 (as amended).

• 9. Any corporation which is a member can appoint one or more corporate representatives who may exercise on its behalf all of the same powers as the corporation could exercise if it were an individual member provided that they do not do so in relation to the same shares.
• 10.

The business which may be dealt with at the AGM includes any statement that the Company has been required under Section 527 of the CA 2006 to publish on its website.
• 13. A member attending the meeting has the right to ask questions relating to the business being dealt with at the meeting in accordance with Section 319A of the CA 2006.

• 16. Voting at the meeting on all resolutions will be conducted by way of a poll rather than a show of hands. The Company considers this to be a more transparent method of voting as member votes will be counted according to the number of shares held. As soon as practicable following the meeting, the results of the voting at the meeting and the number of proxy votes cast for and against and the number of votes actively withheld in respect of each of the resolutions proposed at the meeting will be announced via a Regulatory Information Service and also placed on the Company's website.

Explanatory notes to the resolutions in the Notice of Annual General Meeting

Authority to allot securities (ordinary resolution 14)

Authority was granted to the directors at the AGM of the Company held on 5 May 2022 under Section 551 of the Companies Act 2006 ('CA 2006') to allot ordinary shares or grant rights to subscribe for or convert any security into ordinary shares in the Company. The directors consider it appropriate to renew this authority at the forthcoming AGM for a period expiring at the conclusion of the AGM to be held in 2024 or, if earlier, on 1 July 2024.

Paragraph (a)(i) of ordinary resolution 14 will allow the directors to allot ordinary shares up to a maximum nominal amount of £24,836,353, representing approximately one third (33.33%) of the Company's existing issued share capital (excluding shares held in treasury), calculated as at 17 March 2023 (being the latest practicable date prior to publication of this Notice). In accordance with institutional guidelines issued by The Investment Association, paragraph (a)(ii) of ordinary resolution 14 will allow the directors to allot, including the ordinary shares referred to in paragraph (a)(i) of ordinary resolution 14, additional ordinary shares in connection with a pre-emptive offer by way of a rights issue to ordinary shareholders up to a maximum nominal amount of £49,680,159, representing approximately two thirds (66.67%) of the Company's existing issued share capital (excluding shares held in treasury), calculated as at 17 March 2023.

The proposed new authority will expire at the conclusion of the 2024 AGM of the Company or, if earlier, on 1 July 2024. It is the current intention to renew this authority annually. The directors have no present intention of exercising this authority. However, if they do exercise it, they intend to follow best practice as regards its use, as recommended by The Investment Association.

As at 17 March 2023, the Company's issued share capital amounted to £78,587,609 comprising 275,056,630 ordinary shares of 28 4/7p each and the Company held 14,248,836 ordinary shares in treasury, representing approximately 5% of the Company's issued share capital.

Authority to make political donations and incur political expenditure (ordinary resolution 15)

Subject to limited exceptions, the Companies Act 2006 imposes restrictions on companies making political donations to any political party or other political organisation or to any independent election candidate or incurring political expenditure unless they have been authorised to do so at a general meeting.

The resolution in this connection passed at last year's AGM is due for renewal.

Neither the Company nor any of its subsidiaries has any intention of making any political donation or incurring any political expenditure under the terms of the proposed resolution. However, the CA 2006 defines 'political party', 'political organisation', 'political donation' and 'political expenditure' widely and grey areas remain which lead many UK public limited companies to seek shareholder approval for what may inadvertently amount to a political donation.

Accordingly, in line with best practice, the Company wishes to ensure that neither it nor its subsidiaries risks any breach of the CA 2006 through the undertaking of routine activities, which would not normally be considered to result in the making of political donations and political expenditure being incurred. The proposed authority will expire at the conclusion of the 2024 AGM of the Company or, if earlier, on 1 July 2024.

Disapplication of statutory pre-emption rights (special resolutions A and B)

Special resolutions A and B will allow the directors to allot equity securities for cash pursuant to the authority under ordinary resolution 14, or by way of a sale of treasury shares, without in the first instance offering them to existing shareholders in proportion to their holdings. The authority sought will authorise the directors to issue shares in connection with: (a) a rights issue or other pre emptive offer and otherwise to issue shares for cash up to a nominal value of £3,929,380 which includes the sale on a non pre-emptive basis of any shares the Company holds in treasury for cash. This amount represents 5% of the total ordinary share capital in issue at 17 March 2023 (being the latest practicable date prior to publication of this Notice); and in addition, (b) the financing (or re financing, if the authority is to be used within 6 months after the original transaction) for an acquisition or other capital investment which the Board determines to be as contemplated by the Pre Emption Group's Statement of Principles, to issue shares for cash up to a nominal value of £3,929,380 which includes the sale on a non pre- emptive basis of any shares the Company holds in treasury for cash. This amount also represents 5% of the total ordinary share capital in issue at 17 March 2023.

This dis-application authority is in line with guidance with the Pre Emption Group's Statement of Principles. The authority will expire at the conclusion of the 2024 AGM of the Company or, if earlier, on 1 July 2024. It is the current intention to renew this authority annually.

The directors have no present intention of exercising their authority under special resolutions A and B and further confirm that they have no present intention to issue more than 7.5% of the issued share capital of the Company for cash on a non preemptive basis pursuant to the authority in special resolution A in any rolling three- year period without prior consultation with the shareholders.

Purchase by the Company of its own shares (special resolution C)

Renewal of the authority for the Company to purchase its own shares will be sought at the AGM. The resolution is to authorise the Company to buy back up to 26,080,779 ordinary shares. The resolution specifies the maximum number of ordinary shares which may be purchased, representing nearly 10% of the Company's issued ordinary share capital as at 17 March 2023 (excluding shares held in treasury) and the maximum and minimum prices at which they may be bought, exclusive of expenses, reflecting the requirements of the Companies Act 2006 and the Listing Rules. The directors have no present intention of exercising the authority to purchase the Company's ordinary shares and would only exercise this authority if they were satisfied that any purchase is in the interests of shareholders and will result in an increase in earnings per share of the ordinary share capital in issue after the purchase.

The directors would also give careful consideration to the gearing levels of the Company and its general financial position. The purchase price would be paid out of distributable profits. This authority will expire at the conclusion of the 2024 AGM of the Company or, if earlier, on 1 July 2024. It is the current intention to renew this authority annually.

The CA 2006 enables certain listed companies to hold shares in treasury, as an alternative to cancelling them, following a purchase of own shares. Shares held in treasury may subsequently be cancelled, sold for cash or used to satisfy share options and share awards under employee share schemes.

Once held in treasury, the Company is not entitled to exercise any rights, including the right to attend and vote at meetings in respect of the shares. Further, no dividend or other distribution of the Company's assets may be made to the Company in respect of the treasury shares.

Accordingly, if the directors exercise this authority to purchase shares, the Company will have the option of holding those shares in treasury. Following a purchase of own shares by the Company, the directors may consider holding them in treasury.

The total number of ordinary shares in respect of which there are options or warrants or awards that are outstanding under the Company's share schemes and which are to subscribe for ordinary shares or which could result in the subscription of ordinary shares as at 17 March 2023 (being the latest practicable date prior to publication of this Notice) was 335,373. The proportion of issued ordinary share capital (excluding treasury shares) that the options represented on this date was approximately 0.13% and the proportion of issued ordinary share capital (excluding treasury shares) that they will represent if the full authority to purchase shares (being sought) is used is approximately 0.14%.

Notice of general meetings (special resolution D)

The CA 2006 provides that the notice period required for general meetings of the Company is 21 days. However, shareholders may approve a shorter notice period, which cannot however be less than 14 clear days for general meetings, other than annual general meetings that must be held on at least 21 clear days' notice. It is proposed to seek renewal of the authority that was granted to the directors at the AGM in 2010 to call general meetings other than an annual general meeting on not less than 14 working days' notice. The authority granted by this resolution, if passed, will be effective until the Company's next AGM, when it is intended that a similar resolution will be proposed. The flexibility offered by this resolution will be used where, taking into account the circumstances (and noting the guidance issued by ISS), the directors consider this appropriate in relation to the business of the meeting and in the interests of the Company and shareholders as a whole.
