1. THAT a general meeting other than an AGM may be called on not less than 14 clear days' notice.

The Directors consider that all resolutions to be considered at the AGM are in the best interests of the Company and its shareholders as a whole and are more likely to promote the success of the Company for their benefit. The Directors unanimously recommend that you vote in favour of the proposed resolutions as they intend to do in respect of their own beneficial holdings.

The business of the AGM will be conducted on a poll.

BY ORDER OF THE BOARD

Charles Sherwood Company Secretary 30 April 2025

Registered Office: C/O TMF Group, 13th Floor, One Angel Court, London EC2R 7HJ

Registered Number: 09582467

This explanatory note gives further information in relation to the resolutions listed in the enclosed notice of the 2024 Annual General Meeting.

Resolutions 1 to 12 (inclusive) 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 13 to 16 (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.

Resolution 1: Receipt of the Company's Report and Accounts

The Directors must lay the Company's accounts, the Directors' Report, the Strategic Report and the Auditor's Report before the shareholders at the AGM for approval as this is a legal requirement.

Resolution 2: Directors' Remuneration Report

The Directors' Remuneration Report for the year ended 31 December 2024 can be found on pages 102 to 120 of the Annual Report. The Company's auditors, PricewaterhouseCoopers LLP, have audited those parts of the Directors' Remuneration Report that are required to be audited and their report may be found on pages 121 to 125 of the Annual Report. Under section 439 of the Companies Act 2006, the Company must give shareholders notice of an ordinary resolution approving the Directors' Remuneration Report. This vote is an advisory one and does not affect the actual historical remuneration paid to any individual Director.

Resolutions 3 to 9: Directors

Resolutions 3 to 9 deal with the election and re‑election of Directors. In accordance with the requirements of the UK Corporate Governance Code, all Directors are offering themselves for re‑election.

The biographies of each of the Directors standing for re‑election are on pages 82 to 85 of the Annual Report.

The Board believes that each Director standing for re‑election brings considerable and wide-ranging skills and experience to the Board as a whole. The Board considers that each Director continues to make an effective and valuable contribution to the deliberations of the Board and demonstrates commitment to the role. Upon their appointment to the Board in June 2015 (Dr. Kucherlapati and Dr. LaMattina), in October 2020 (Ms. Mazumdar-Shaw), in March 2022 (Ms. Barber‑Lui), and in August 2024 (Dr. Michele Holcomb) the Board evaluated the independence of the five above mentioned Directors, in accordance with the UK Corporate Governance Code. At the time of writing, the Board considers that there have been no changes in circumstances or otherwise which might affect, or could appear to affect, the independent judgment or character of these Directors. In reaching this determination, the Board had regard to (i) their directorships and links with other Directors through their involvement in the Company's subsidiaries; and (ii) their equity interests in the Company and its subsidiaries.

Further details of these directorships and interests are set out on pages 82 to 85 and on page 117 of the Annual Report. The Board is satisfied that the judgment, experience and challenging approach adopted by each of Ms.Barber‑Lui, Dr. Kucherlapati, Dr. Michele Holcomb, Dr. LaMattina and Ms. Mazumdar-Shaw should ensure that they each make a significant contribution to the work of the Board and its committees. Therefore, the Board has determined that Ms.Barber‑Lui, Dr. Kucherlapati, Dr. Michele Holcomb, Dr. LaMattina and Ms. Mazumdar-Shaw are of independent character and judgment, notwithstanding the circumstances described at (i) and (ii) above.

Save as disclosed above, none of the independent non-executive Directors seeking election or re‑election has any existing or previous relationship, transaction or arrangement with the Company, its Directors, any Explanation of Annual General Meeting Business controlling shareholder of the Company or any associate of a controlling shareholder of the Company within the meaning of Listing Rule 13.8.17R (1).

The Nomination Committee will lead the process for appointing new Directors in the future, by evaluating the particular skills, knowledge, independence, experience and diversity, including gender, that would benefit and balance the Board most appropriately for each appointment. Having established appropriate selection criteria, the Nomination Committee is responsible for identifying and recommending suitable candidates to the Board for its approval, and may consult with external consultants, advisers and Board members on prospective appointments.

Resolutions 4 and 8 deal with the election of nonindependent Directors (being Dr. Langer and Dr. Chowrira, the Company's Chief Executive Officer).

Resolutions 10 & 11: Appointment and Remuneration of Auditors

Under section 489 of the Companies Act 2006, auditors of a public company have to be appointed before the end of each AGM at which the Company's annual accounts are presented. The Audit Committee, which has evaluated the effectiveness and independence of the external auditors, has recommended to the Board that PricewaterhouseCoopers LLP be re-appointed as auditor of the Company, to hold office from the conclusion of the AGM until the conclusion of the next AGM at which accounts are presented.

Resolution 11 authorises the Audit Committee to determine the auditor's remuneration.

Resolution 12: Directors' Authority to Allot

Generally, the Directors may only allot shares in the Company (or grant rights to subscribe for, or to convert any security into, shares in the Company) if they have been authorised to do so by shareholders. Resolution 13 renews a similar authority given at last year's AGM and is in two parts.

Paragraph a. of this resolution would give the Directors the authority to allot ordinary shares or grant rights to subscribe for or convert any securities into shares up to an aggregate nominal amount equal to £800,631.45 (representing 80,063,145 Ordinary Shares). This amount represents approximately one-third of the issued ordinary share capital (excluding treasury shares) of the Company as at 30 April 2025, the latest practicable date prior to publication of this Notice.

In line with guidelines issued by the Investment Association, paragraph b. of this resolution would give the Directors the authority to allot ordinary shares or grant rights to subscribe for or convert any securities into shares up to a further aggregate nominal amount equal to one third of the issued ordinary share capital of the Company (excluding treasury shares) as at 30 April 2025, the latest practicable date prior to publication of this Notice, representing 80,063,145 Ordinary Shares, which will be applied (if at all) to fully pre-emptive rights issues only.

The authority sought under this resolution will expire at the earlier of 16 September 2026 and the conclusion of the AGM of the Company held in 2026. The Directors have no present intention to exercise the authority sought under this resolution. However, if they do exercise the authority, the Directors intend to follow Investment Association guidelines concerning its use (including as regards the Directors standing for re‑election in certain cases). As at 30 April 2025, the Company holds 17,738,040 shares in treasury.

Resolutions 13 & 14: Disapplication of Pre‑emption Rights

Generally, if the Directors wish to allot new shares or other equity securities (within the meaning of section 560 of the Act) for cash, or sell treasury shares for cash, then under the Companies Act 2006 they must first offer such shares or securities to shareholders in proportion to their existing holdings. These statutory pre-emption rights may be disapplied by shareholders.

Paragraph a. of Resolution 13, which will be proposed as a special resolution, seeks to authorise the Directors to issue equity securities of the Company for cash, free from statutory pre-emption rights in connection with a rights issue as defined in Resolution 13.

Paragraph b. of Resolution 13 seeks authority to issue equity securities, free from statutory pre-emption rights up to an aggregate nominal value of £240,189.45, which represents approximately 10 percent of the Company's existing ordinary share capital as at 30 April 2025, being the latest practicable date prior to the publication of the Notice.

Resolution 14 seeks authority to issue equity securities free from statutory pre-emption rights up to an aggregate nominal value of an additional £240,189.45, which represents approximately 10 percent of the Company's existing ordinary share capital as at 30 April 2025, being the latest practicable date prior to the publication of the Notice, to be used only for the purposes of financing a transaction which the Directors determine to be an acquisition or other 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.

The disapplication authorities under Resolutions 13 and 14 are in line with guidance set out in the Statement of Principles. The Statement of Principles allow a board to allot shares for cash otherwise than in connection with a pre-emptive offer (i) up to 10 per cent. of a company's issued share capital for use on an unrestricted basis, (ii) up to a further 10 per cent. of a company's issued share capital for use in connection with an acquisition or specified capital investment announced either contemporaneously with the issue, or which has taken place in the preceding twelve-month period and is disclosed in the announcement of the issue.

The power will expire at the earlier of 16 September 2026 and the conclusion of the AGM of the Company held in 2026. The Directors have no present intention to exercise the authority sought under this resolution.

Resolution 15: Authority to undertake Market Purchases of Own Shares

This resolution would give the Company the authority to purchase up to 10 percent of its issued Ordinary Shares (excluding any treasury shares). The Directors will exercise this authority only when to do so would be in the best interests of the Company, and of its shareholders generally, and could be expected to result in an increase in the earnings per share of the Company. Any purchases of Ordinary Shares would be by means of market purchases through the London Stock Exchange.

The minimum price, exclusive of expenses, which may be paid for an Ordinary Share is its nominal value. The maximum price, exclusive of expenses, which may be paid for an Ordinary Share is the highest of:

• (i) an amount equal to 5 percent above the average market value for an Ordinary Share for the five business days immediately preceding the date of the purchase; and
• (ii) the higher of the price of the last independent trade and the highest current independent bid on the trading venues where the purchase is carried out at the relevant time.

Ordinary Shares purchased by the Company pursuant to this authority may be held in treasury or may be cancelled. The Directors will consider holding any Ordinary Shares the Company may purchase as treasury shares. Treasury shares may be resold for cash or used to satisfy share options and share awards under the Company's share incentive schemes but all rights attaching to them, including voting rights and any right to receive dividends, are suspended while they are held in treasury. Treasury shares may also be cancelled.

The share buyback programme announced on 5 May 2022 completed on 8 February 2024. Any ordinary shares repurchased under this programme are held in treasury to the extent required to satisfy existing share options and share awards under the Company's share incentive schemes, with the remainder being cancelled.

The tender offer announced by the Company on 20 May 2024 completed on 24 June 2024. The 31,540,670 ordinary shares purchased pursuant to the tender offer were cancelled by the Company.

The Company currently holds 17,738,040 shares in treasury.

As at 30 April 2025, the latest practicable date prior to publication of this Notice, the Company had options outstanding over 12,975,653 Ordinary Shares. These options represent 5.0 percent of the Company's issued ordinary share capital and would represent 5.5 percent of the Company's issued ordinary share capital if the full buy-back authority being sought is used and all Ordinary Shares bought back are cancelled and not held in treasury and re-issued. There are no warrants outstanding over any Ordinary Shares.

Resolution 16: Notice Period for General Meetings

Under the Companies Act 2006 the notice period required for all general meetings of the Company is 21 clear days, though shareholders can approve a shorter notice period for general meetings that are not AGMs, which cannot however be less than 14 clear days. AGMs will continue to be held on at least 21 clear days' notice. The shorter notice period would not be used as a matter of routine for such meetings, but only where the flexibility is merited by the business of the meeting and is thought to be to the advantage of shareholders as a whole. If granted, this authority will be effective until the Company's next AGM.

Proxy appointment

• 1 A member is entitled to appoint another person as his proxy to exercise all or any of his rights to attend and to speak and vote at the AGM, or any adjournment thereof. A proxy need not be a shareholder of the Company. A shareholder may appoint more than one proxy in relation to the AGM provided that each proxy is appointed to exercise the rights attached to a different share or shares held by that shareholder. Failure to specify the number of shares each proxy appointment relates to or specifying a number which when taken together with the number of shares set out in the other proxy appointments is in excess of the number of shares held by the shareholder may result in the proxy appointment being invalid. A proxy may only be appointed in accordance with the procedures set out in notes 2-3 and 10 below and the notes to the proxy form.
• 2 A form of proxy is enclosed. The appointment of a proxy will ordinarily not prevent a member from subsequently attending and voting at the meeting in person. When appointing more than one proxy, complete a separate proxy form in relation to each appointment. Additional proxy forms may be obtained by contacting the Company's registrar or the proxy form may be photocopied. State clearly on each proxy form the number of shares in relation to which the proxy is appointed.
• 3 To appoint a proxy, the form of proxy and any power of attorney or other authority (if any) under which it is executed (or a duly certified copy of any such power or authority), must be either (a) sent to the Company's Registrars, Computershare Investor Services PLC, at The Pavilions, Bridgwater Road, Bristol BS99 6ZY, or (b) the proxy appointment must be lodged using the CREST Proxy Voting Service in accordance with note 10 below, or (c) the proxy appointment must be registered electronically on the website www.investorcentre.co.uk/eproxy or by using the QR Code printed on the form of proxy in each case so as to be received no later than 4 pm BST (11 a.m. EDT) on Thursday 12 June 2025 (or, if the meeting is adjourned, no later than 48 hours (excluding any part of a day that is not a working day) before the time of any adjourned meeting).

If you are an institutional investor, you may be able to appoint a proxy electronically via the Proxymity platform, a process which has been agreed by the Company and approved by the Registrar. For further information regarding Proxymity, please go to www. proxymity.io. Your proxy must be lodged by 4 p.m. BST (11 a.m. EDT) on Thursday 12 June 2025 in order to be considered valid. 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.

Joint shareholders

4 In the case of joint holders of a share the vote of the senior who tenders a vote, whether in person or by proxy, shall be accepted to the exclusion of the votes of the other joint holders, and for this purpose seniority shall be determined by the order in which the names appear in the register of members in respect of the share.

Nominated persons

5 The right to appoint a proxy does not apply to persons whose shares are held on their behalf by another person and who have been nominated to receive communications from the Company in accordance with Section 146 of the Companies Act 2006 ("Nominated Persons"). Nominated Persons may have a right under an agreement with the member who holds the shares on their behalf to be appointed (or to have someone else appointed) as a proxy. Alternatively, if Nominated Persons do not have such a right or do not wish to exercise it, they may have a right under such an agreement to give instructions to the person holding the shares as to the exercise of voting rights.

Information about shares and voting

6 Holders of ordinary shares are entitled to vote at general meetings of the Company. The total number of issued ordinary shares in the Company on 30 April 2025, which is the latest practicable date before the publication of this document is 257,927,489.

The Company holds 17,738,040 ordinary shares in treasury, therefore the total voting rights in the Company as at 30 April 2024 were 240,189,449 carrying one vote each on a poll.

Right to attend and vote

7 Entitlement to attend and vote at the meeting, and the number of votes which may be cast at the meeting, will be determined by reference to the Company's register of members at 4 p.m. BST (11 a.m. EDT) on Thursday 12 June 2025 or, if the meeting is adjourned, no later than 48 hours (excluding any part of a day that is not a working day) before the time fixed for the adjourned meeting (as the case may be). In each case, changes to the register of members after such time will be disregarded.

8 We recommend that all shareholders appoint the chair of the meeting as proxy. This will ensure that your vote will be counted even if attendance at the meeting is restricted.

CREST members

9 CREST members who wish to appoint a proxy or proxies through the CREST electronic proxy appointment service may do so for the meeting (and any adjournment of the meeting) by following the procedures described in the CREST Manual available on the website of Euroclear UK and International Limited ("Euroclear") at 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.

In order for a proxy appointment or instruction made by means of CREST 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 instructions, as described in the CREST Manual.

The message (regardless of whether it constitutes the appointment of a proxy or 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 Computershare Investor Services PLC Participant ID 3RA50 by the latest time(s) for receipt of proxy appointments specified in note 3 above.

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 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 a proxy appointed through CREST should be communicated to him by other means.

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 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 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

10 Any corporation which is a member can appoint one or more corporate representatives who may exercise on its behalf all of its powers as a member provided that (where there is more than one representative and the vote is otherwise than on a show of hands) they do not do so in relation to the same shares.

Audit concerns

11 Shareholders should note that, under section 527 of the Companies Act 2006, members meeting the threshold requirements set out in that section have the right to require the Company to publish on a website a statement setting out any matter relating to: (i) the audit of the Company's accounts (including the auditor's report and the conduct of the audit) that are to be laid before the AGM for the financial year ended 31 December 2024; or (ii) any circumstance connected with an auditor of the Company appointed for the financial year ended 31 December 2024 ceasing to hold office since the previous meeting at which annual accounts and reports were laid.

Any such request must: (i) identify the statement to which it relates, by either setting out the statement in full or, if supporting a statement requested by another shareholder, clearly identifying the statement which is being supported; and (ii) be received by the Company at least one week before the meeting. The Company may not require the shareholders requesting any such website publication to pay its expenses in complying with sections 527 or 528 (requirements as to website availability) of the Companies Act 2006. Where the Company is required to place a statement on a website under section 527 of the Companies Act 2006, 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 for the relevant financial year includes any statement that the Company has been required under section 527 of the Companies Act 2006 to publish on a website.

Questions

12 Any member attending the AGM has the right to ask questions. The Company must cause to be answered any such question relating to the business being dealt with at the meeting but no such answer need be given if (a) to do so would interfere unduly with the preparation for the meeting 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 meeting that the question be answered.

14 Each of the resolutions to be put to the meeting will be voted on by way of a poll and not a show of hands. A poll reflects the number of voting rights exercisable by each member and so the Board considers it a more democratic method of voting. Members and proxies will be asked to complete a poll card to indicate how they wish to cast their votes. These cards will be collected at the end of the meeting. The results of the poll will be published on the Company's website and notified to the UK Listing Authority once the votes have been counted and verified.

Website publication of audit concerns

15 Under section 527 of the Act, members meeting the threshold requirements set out in that section have the right to require the Company to publish on a website a statement setting out any matter relating to: (i) the audit of the Company's accounts (including the auditors' report and the conduct of the audit) that are to be laid before the AGM; or (ii) 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 Act. The Company may not require the shareholders requesting any such website publication to pay its expenses in complying with sections 527 or 528 of the Act. Where the Company is required to place a statement on a website under section 527 of the 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 Act to publish on a website.
