TABLE OF CONTENTS

Please refer to the attached proxy statement for detailed information on each of the resolutions, which are set forth in the attached proxy statement as resolutions 1 through 10. We encourage you to read the proxy statement in its entirety before voting. Our board of directors has approved each resolution and recommends that shareholders entitled to vote at the AGM vote in favor of each of the resolutions.
Resolutions 1 through 10 will be proposed as ordinary resolutions and under English law, assuming that a quorum is present, an ordinary resolution is passed on a poll if it is approved by holders representing a simple majority of the total voting rights of shareholders present (in person or by proxy) who (being entitled to vote) vote on the resolution.
Voting on all resolutions at the AGM will be conducted by way of a poll, rather than a show of hands.
The result of the shareholder votes on the ordinary resolutions in resolutions 4, 8 and 9 will not require our board of directors or any committee thereof to take any action. Our board of directors values the opinions of our shareholders as expressed through such votes and will carefully consider the outcome of the votes on these resolutions.
Only those ordinary shareholders of record as of 6:00 p.m. London time (1:00 p.m. Eastern Daylight Time) on Friday, May 22, 2026 will be entitled to attend, speak and vote at the AGM. Ordinary shareholders attending the AGM will have the right to ask questions at the AGM in accordance with the Companies Act. Persons intending to attend the AGM in person will need a QR code to access the AGM venue. Such QR code will need to be displayed on a smartphone or similar device. A QR code will be able to be obtained in advance by emailing the registrar at corporate-representatives@computershare.co.uk with your full name and email address. Persons who have not obtained a QR code in advance will be able to obtain one at the AGM venue.
Your vote is important, regardless of the number of ordinary shares or American Depositary Shares (“ADSs”) you own. Holders of ordinary shares who attend the AGM in person or electronically via meetnow.global/IHCAGM2026 will be able to vote during the AGM. However, to make sure your shares are represented at the AGM, please vote as soon as possible. Holders of ordinary shares entitled to attend and vote at the AGM are entitled to appoint a proxy (or, if they hold more than one ordinary share, proxies) to exercise all or any of their rights to attend, speak and vote at the AGM. Such proxy need not be one of our shareholders of record. Holders of our ordinary shares may vote by proxy either over the internet or by returning a form of proxy in the envelope provided by no later than 2:00 p.m. London time (9:00 a.m. Eastern Daylight Time) on Friday, May 22, 2026. In addition, you may be able to appoint a proxy electronically via the CREST electronic proxy appointment service or the Proxymity platform. You may revoke your proxy in the manner described in the accompanying proxy statement. Holders of our ADSs may vote by following the voting instructions in the attached proxy statement.
The results of the polls taken on the resolutions at the AGM and any other information required by the Companies Act will be made available on our website (https://ir.immunocore.com) as soon as reasonably practicable following the AGM and available for the required period thereafter. The results will also be announced by the filing of a Current Report on Form 8-K with the U.S. Securities and Exchange Commission. The inclusion of our website address here and elsewhere in the attached proxy statement does not include or incorporate by reference the information on our website into this Notice or the proxy statement.

PROXY STATEMENT
FOR THE 2026 ANNUAL GENERAL MEETING OF SHAREHOLDERS
TO BE HELD ON MAY 27, 2026
QUESTIONS AND ANSWERS ABOUT THESE PROXY MATERIALS AND VOTING
We have sent you this proxy statement and the enclosed form of proxy because the board of directors of Immunocore Holdings plc is soliciting your proxy to vote at our upcoming annual general meeting of shareholders (the “AGM”). As used in this proxy statement, references to “we,” “us,” “our” and “Immunocore” refer to Immunocore Holdings plc.
The Notice of 2026 Annual General Meeting, this proxy statement, the form of proxy, our U.K. statutory annual accounts and reports for the year ended December 31, 2025 (“2025 U.K. Annual Report”) and our annual report on Form 10-K for the year ended December 31, 2025 (the “Annual Report on Form 10-K,” and collectively with the Notice of 2026 Annual General Meeting, this proxy statement, the 2025 U.K. Annual Report and the form of proxy, the “Proxy Materials”), will be made available (either electronically or by post) to our ordinary shareholders of record for the first time on or about April 16, 2026.
While this proxy statement is made available to our ordinary shareholders of record, this document will also be sent to holders of our American Depositary Shares (“ADSs”) for the first time on or about April 16, 2026 and contains information relevant to holders of ADSs. In addition, we have provided brokers, dealers, bankers, and their nominees, at our expense, with copies of the Proxy Materials so that our record holders can supply these materials to the beneficial owners of our ordinary shares.
When is the AGM?
The AGM will be held on Wednesday, May 27, 2026, at 2:00 p.m. London time (9:00 a.m. Eastern Daylight Time), at the offices of Cooley (UK) LLP, 22 Bishopsgate, London EC2N 4BQ, United Kingdom and electronically via meetnow.global/IHCAGM2026. The AGM will be held as a hybrid general meeting so that holders of ordinary shares will be able to participate in the meeting in person or electronically.
Why am I receiving these materials?
We have made available the Proxy Materials to you because you are an ordinary shareholder of record and our board of directors is soliciting your proxy to vote at the AGM, including at any adjournments or postponements thereof. You do not need to attend the AGM in person to vote your shares.
All holders of ordinary shares will also be able to submit a proxy electronically using the website www.investorcentre.co.uk/eproxy. In addition, you may also be able to appoint a proxy electronically via the CREST electronic proxy appointment service or the Proxymity platform. To submit your proxy, simply follow the instructions in this proxy statement. In addition, if you have elected to receive communications from us in hard-copy form, you can vote by completing and returning the paper form of proxy enclosed with this document to our registrar, Computershare Investor Services PLC (“Computershare”).
All proxies, however submitted, must be lodged with Computershare, by no later than 2:00 p.m. London time (9:00 a.m. Eastern Daylight Time) on Friday, May 22, 2026. Materials for ADS holders of record, including this proxy statement, the Annual Report on Form 10-K, the 2025 U.K. Annual Report and an ADS proxy card, will be mailed on or about April 16, 2026 to all ADS holders, including banks, brokers and nominees, who are registered as holders of ADSs in the ADS register by 5:00 p.m. Eastern Daylight Time on April 2, 2026, the record date for ADS holders.
Who can vote at the AGM?
Ordinary Shareholders of Record
Only ordinary shareholders of record registered in the register of members at 6:00 p.m. London time (1:00 p.m. Eastern Daylight Time) on Friday, May 22, 2026 will be entitled to vote at the AGM. As of April 2, 2026 (being the last practicable date before the circulation of this proxy statement), there were 50,831,928 ordinary shares issued and

outstanding and entitled to vote. As an ordinary shareholder of record, you may vote at the AGM or by proxy. We encourage you to vote prior to the AGM by proxy over the internet or by mail or, if applicable, via the CREST electronic proxy appointment service or the Proxymity platform, as instructed below to ensure your vote is counted.
If, on or prior to May 22, 2026, you sell or transfer our ordinary shares that you currently hold, your form of proxy can no longer be used and if submitted (whether before or after you sell or transfer your ordinary shares) will be treated as invalid. Please pass this document to the person who arranged the sale or transfer for delivery to the purchaser or transferee. The purchaser or transferee should contact Lily Hepworth, Company Secretary, to request a new form of proxy for their use.
Holders of our deferred shares do not have the right to receive notice of, or to attend and vote at, the AGM in respect of such deferred shares.
Beneficial Owners of Ordinary Shares which are Registered in the Name of a Broker, Bank or Other Agent
If, on May 22, 2026, your ordinary shares were held in an account at a brokerage firm, bank or other similar organization and you are the beneficial owner of shares, these Proxy Materials should be forwarded to you by that organization. The organization holding your account is considered the shareholder of record for purposes of voting at the AGM. You are encouraged to provide voting instructions to your broker or other agent so that they may submit a proxy.
Holders of American Depositary Shares
If you or your brokerage firm, bank or nominee is registered as a holder of ADSs in the ADS register at 5:00 p.m. Eastern Daylight Time on April 2, 2026 (the record date for ADS holders), you are entitled to exercise your vote as a holder of an interest in our share capital represented by ADSs. If you hold ADSs through a brokerage firm, bank or nominee on April 2, 2026, the materials for ADS holders, including the ADS proxy card, will be sent to that organization. The organization holding your account is considered the ADS holder of record. Please reach out to that organization to provide your voting instructions.
Please note that ADS proxy cards submitted by ADS holders must be received by the depositary, Citibank, N.A., no later than 10:00 a.m. Eastern Daylight Time on Monday, May 18, 2026. Citibank, N.A. will collate all votes properly submitted by ADS holders and submit a vote on behalf of all ADS holders.
What are the differences between ADS holders and ordinary shareholders?
Citibank, N.A., as depositary, executes and delivers ADSs on our behalf. We are requesting Citibank, N.A., which holds the ordinary shares represented by the ADSs, to seek ADS holders’ instructions as to voting for the AGM. As a result, ADS holders may instruct Citibank, N.A., as depositary, to vote the ordinary shares represented by their ADSs.
Because we have asked Citibank, N.A. to seek the instructions of ADS holders, Citibank, N.A. will notify ADS holders of the upcoming vote and arrange to deliver the Proxy Materials to them. Citibank, N.A., as depositary, then tries, as far as practicable, to vote the ordinary shares as our ADS holders instruct. We cannot guarantee that ADS holders will receive this proxy statement and the other proxy materials from Citibank, N.A. in time to permit them to instruct Citibank, N.A., as depositary, to vote their shares. In addition, there may be other circumstances in which ADS holders may not be able to exercise voting rights. Furthermore, ADS holders can exercise their right to vote the ordinary shares underlying their ADSs by exchanging their ADSs for ordinary shares. However, even though we are subject to U.S. domestic issuer proxy rules and our shareholder meetings are announced via press release and in our filings with the Securities and Exchange Commission (the “SEC”), ADS holders may not receive proxy materials about the AGM early enough to exchange their ADSs for ordinary shares.
ADS holders are not required to be treated as holders of ordinary shares and do not have the rights of holders of ordinary shares.
What is the difference between a shareholder of record and a beneficial owner?
These terms describe how your ordinary shares are held. If your ordinary shares are registered directly in our register of members maintained by Computershare, our registrar, you are a shareholder of record and the Proxy Materials are being sent directly, or otherwise being made available, to you. If your ordinary shares are held in the name of a broker, bank, or other nominee, you are a beneficial owner of the shares held by your broker, bank or other nominee and the Proxy

Materials are being made available or forwarded to you by your broker, bank, or other nominee, who is treated as the shareholder of record. As the beneficial owner, you have the right to direct your broker, bank, or other nominee on how to vote your ordinary shares by following the instructions on the voting instructions provided to you by such broker, bank or other nominee.
What are the requirements to approve each of the resolutions?
You may cast your vote for or against resolutions 1 through 10 or abstain from voting your shares on one or more of these resolutions.
Resolutions 1 through 10 will be proposed as ordinary resolutions. Under English law, assuming that a quorum is present, an ordinary resolution is passed on a poll if it is approved by holders representing a simple majority of the total voting rights of shareholders present (in person or by proxy) who (being entitled to vote) vote on the resolution.
The result of the shareholder votes on ordinary resolutions 4, 8 and 9 regarding advisory approval of the executive compensation of our named executive officers, receipt and adoption of the 2025 U.K. Annual Report and approval of the directors’ remuneration report for the year ended December 31, 2025 will not require our board of directors or any committee thereof to take any action. Our board of directors values the opinions of our shareholders as expressed through such votes and will carefully consider the outcome of the votes on these resolutions.
What are the voting recommendations of our board of directors regarding the election of directors and other resolutions?
The following table summarizes the items that will be brought for a vote of our shareholders at the AGM, along with the voting recommendations of our board of directors.

10 |  |  | To authorize the Company and all of its subsidiaries to make political donations and incur political expenditure |  |  | FOR

What constitutes a quorum?

If there is no quorum within fifteen minutes (or such longer interval as the chair of the AGM in their absolute discretion thinks fit) from the time fixed for the start of the AGM, or if a quorum ceases to be present during the AGM, the AGM will stand adjourned to such time, date and place or places and/or by means of such electronic facility or facilities as may be fixed by the chair of the AGM (being not less than 10 clear days later). If at such adjourned meeting, a quorum is not present within 15 minutes from the time appointed for the holding of the meeting, the meeting shall be dissolved.

TABLE OF CONTENTS

How do I vote my shares?
You may vote “FOR” or “AGAINST” or abstain from voting on the applicable resolution. The procedures for voting are as follows:
Ordinary Shareholders of Record
If you are an ordinary “shareholder of record,” you may vote at the AGM or by proxy. We urge you to vote by proxy over the internet or by mail or, if applicable, via the CREST electronic proxy appointment service or the Proxymity platform, as instructed below to ensure your vote is counted. You may also attend and vote at the AGM in person or by using the electronic platform via meetnow.global/IHCAGM2026. If you intend to attend the AGM in person, you will need a QR code to access the AGM venue, which QR code will need to be displayed on a smartphone or similar device. You will be able to obtain a QR code in advance of the AGM by emailing the registrar at corporate-representatives@computershare.co.uk with your full name and email address. Persons who have not obtained a QR code in advance will be able to obtain one at the AGM venue.
You may still attend the AGM and vote in person or via the electronic platform during the AGM even if you have already voted by proxy.
You 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 ordinary share(s)). To appoint more than one proxy, you should contact our registrar, Computershare. Such proxy need not be a shareholder of record but must attend the AGM to represent you for your vote to be counted. We encourage all shareholders to appoint the Chairman of the AGM as their proxy.
You may vote using one of the following methods:

• | To vote on the internet, go to https://www.investorcentre.co.uk/eproxy to appoint a proxy electronically and follow the instructions (see instructions on form of proxy).

• | If you have received a hard-copy form of proxy simply complete, sign and date the enclosed form of proxy and return it promptly in the envelope provided.

• | CREST members who wish to appoint a proxy or proxies through the CREST electronic proxy appointment service may do so for the AGM (and any adjournment of the AGM) by using the procedures described in the CREST Manual (available from 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. 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 UK & International Limited’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 (ID: 3RA50) by 2:00 p.m. London time (9:00 a.m. Eastern Daylight Time) on May 22, 2026. For this purpose, the time of receipt will be taken to mean 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 & International Limited 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 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 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 addition, 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. We may treat a CREST Proxy Instruction as invalid in the circumstances set out in Regulation 35(5)(a) of the Uncertificated Securities Regulations 2001.

• | You may also be able to appoint a proxy electronically via the Proxymity platform, a process to which we have agreed and which has been approved by Computershare, our registrar. For further information regarding

TABLE OF CONTENTS

Proxymity, please go to www.proxymity.io. 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 via the Proxymity platform.

• | To vote in person, come to the AGM and we will give you a poll card when you arrive.

• | If you attend the AGM electronically, you can vote by using the online platform at meetnow.global/IHCAGM2026.

All proxies (however submitted) must be lodged with Computershare, our registrar, by no later than 2:00 p.m. London time (9:00 a.m. Eastern Daylight Time) on May 22, 2026.
If you properly give instructions as to your proxy appointment by executing and returning a form of proxy, or by submitting your proxy online, and your proxy appointment is not subsequently revoked, your shares will be voted in accordance with your instructions. Where no specific instruction is given by you, your proxy may vote at their discretion or refrain from voting, as they see fit.
Beneficial Owners of Ordinary Shares which are Registered in the Name of a Broker, Bank or Other Agent
If your ordinary shares are held in an account at a brokerage firm, bank or similar organization, you should follow directions provided by your broker, bank or other nominee.
Holders of American Depositary Shares
If you are a holder of ADSs, you should follow the directions on the ADS proxy card you received.
Please note that ADS proxy cards submitted by ADS holders must be received by Citibank, N.A. no later than 10:00 a.m. Eastern Daylight Time on Monday, May 18, 2026. Citibank, N.A. will collate all votes properly submitted by ADS holders and submit a vote on behalf of all ADS holders.
Holders of ADSs are unfortunately not entitled to attend and vote at the AGM in person or via the electronic platform.
How will my ordinary shares or ADSs be voted if I do not specify how they should be voted?
If you sign and send your form of proxy but do not indicate how you want your ordinary shares to be voted, your shares may be voted by the person that you appoint as your proxy as he or she sees fit or such person may abstain in relation to any business of the AGM. As a reminder, we urge all shareholders to appoint the Chairman of the AGM as your proxy.
If a holder of ADSs does not submit an ADS proxy card to Citibank, N.A. by the deadline specified, the ADS holder shall be deemed to have instructed Citibank, N.A. to give a discretionary proxy to a person designated by us to vote the ordinary shares represented by his or her ADSs (provided that no such discretionary proxy shall be given if we inform Citibank, N.A. that we do not want such proxy to be given, substantial opposition exists or the rights of ADS holders may be adversely affected). If the enclosed ADS proxy card is signed but is missing voting instructions with respect to any resolution, then Citibank, N.A. will deem the ADS holder to have instructed it to vote in favor of such resolutions. If the enclosed ADS proxy card is improperly completed, Citibank, N.A. will not vote the ADSs to which such ADS proxy card relates; in particular, if more than one voting box is marked for any resolution, the ADS holder shall be deemed to have directed Citibank, N.A. to abstain on the resolution concerned.
Can I change my vote or revoke a proxy?
An ordinary shareholder of record can revoke his, her or its proxy before 2:00 p.m. London time (9:00 a.m. Eastern Daylight Time) on May 22, 2026 (the deadline for submission of proxies) in one of the following ways:

• | entering a new vote over the internet;

• | submitting another signed form of proxy bearing a later date;

• | amending an instruction via the CREST electronic proxy appointment service;

• | if you are an institutional investor that has appointed a proxy electronically through Proxymity, by entering a new voting instruction via your voting platform; or

• | an ordinary shareholder of record may change his or her vote by voting in person or electronically at the AGM.

Who counts the votes?
Computershare has been engaged as our independent agent to tabulate shareholder votes. If you are an ordinary shareholder of record, you can return your executed form of proxy to Computershare for tabulation or submit your proxy electronically either over the Internet at www.investorcentre.co.uk/eproxy (see instructions on form of proxy), via the CREST electronic proxy appointment service or through Proxymity.

RESOLUTION 4
ADVISORY VOTE ON EXECUTIVE COMPENSATION
Under the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) and Section 14A of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), our shareholders are entitled to vote to approve, on an advisory basis, the compensation of our named executive officers as disclosed in this proxy statement in accordance with SEC rules. You are encouraged to review the section titled “Executive Compensation” and, in particular, the section titled “Executive Compensation—Compensation Discussion and Analysis” in this proxy statement, which provide a comprehensive review of our executive compensation program and its elements, objectives and rationale.
This vote is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers and the philosophy, policies and practices described in this proxy statement. The compensation of our named executive officers subject to the vote is disclosed in the compensation tables and the related narrative disclosure contained in this proxy statement. We believe that our compensation policies and decisions are consistent with current market practices. Compensation of our named executive officers is designed to enable us to attract and retain talented and experienced executives to lead us successfully in a competitive environment.
Accordingly, our board of directors is asking the shareholders to indicate their support for the compensation of our named executive officers as described in this proxy statement by casting a non-binding advisory vote “FOR” the following resolution:
“RESOLVED, that the shareholders of Immunocore Holdings plc (the “Company”) hereby approve, on a non-binding, advisory basis, the compensation of the Company’s named executive officers, as disclosed in the Company’s proxy statement for the 2026 Annual General Meeting of Shareholders, pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, the compensation tables and the accompanying narrative.”
Because the vote is advisory, it is not binding on Immunocore or our board of directors. Nevertheless, the views expressed by our shareholders, whether through this vote or otherwise, are important to management and our board of directors and, accordingly, the board of directors and the remuneration committee intend to consider the results of this vote in making determinations in the future regarding executive compensation arrangements.
Vote Required
Advisory (non-binding) approval of our executive compensation requires the approval of holders representing a simple majority of the total voting rights of shareholders present in person or by proxy who (being entitled to vote) vote on the matter.
THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR
THE APPROVAL OF THE EXECUTIVE COMPENSATION PAID
TO OUR NAMED EXECUTIVE OFFICERS.

REGISTERED PUBLIC ACCOUNTING FIRM FOR THE YEAR ENDING DECEMBER 31, 2026
RESOLUTION 6
RE-APPOINTMENT OF DELOITTE LLP AS OUR U.K. STATUTORY AUDITORS, TO HOLD OFFICE UNTIL THE CONCLUSION OF THE NEXT ANNUAL GENERAL MEETING OF SHAREHOLDERS
RESOLUTION 7
AUTHORIZATION FOR THE AUDIT COMMITTEE TO DETERMINE THE U.K. STATUTORY AUDITORS’ REMUNERATION FOR THE YEAR ENDING DECEMBER 31, 2026
The audit committee of our board of directors is responsible for the selection, appointment and negotiation of the remuneration of our U.S. independent registered public accounting firm and our U.K. statutory auditors. The audit committee has approved the appointment of Deloitte LLP, a limited liability partnership organized under the laws of England (“Deloitte”) as our U.S. independent registered public accounting firm for our fiscal year ending December 31, 2026 and the re-appointment of Deloitte as our U.K. statutory auditors until the conclusion of our 2027 annual general meeting of shareholders. In resolutions 5 and 6, we are asking our shareholders to ratify the selection of Deloitte as our U.S. independent registered public accounting firm and to re-appoint Deloitte as our U.K. statutory auditors.
Our organizational documents do not require that the shareholders ratify the selection of Deloitte as our U.S. independent registered public accounting firm. However, the audit committee is submitting the selection of Deloitte to the shareholders for ratification as a matter of good corporate practice. Even if the selection of Deloitte is ratified, the audit committee in its discretion may direct the appointment of a different U.S. independent registered public accounting firm at any time during the year if the audit committee determines to make such a change. In the event our shareholders fail to ratify the selection of Deloitte, the audit committee will consider whether to select other auditors for the Company for the year ending December 31, 2026.
In accordance with the Companies Act, our U.K. statutory auditors must be re-appointed at each meeting at which our U.K. annual report and accounts are presented to our shareholders. If this resolution is not approved by our shareholders at the AGM, the audit committee may appoint auditors to fill the vacancy.
Deloitte has served as our independent registered public accounting firm since 2023. We expect representatives of Deloitte to be in attendance at the AGM, to make a statement if they so desire, and to be available to respond to appropriate questions.
In accordance with the Companies Act, the remuneration of our U.K. statutory auditors must be fixed in a general meeting of shareholders or in such manner as may be determined in a general meeting of shareholders. In resolution 7, we are asking our shareholders to authorize the audit committee to determine the remuneration of Deloitte as our U.K. statutory auditors for the year ending December 31, 2026.
Principal Accountant Fees and Services
The following table represents aggregate fees billed to us by Deloitte for the periods set forth below:

|  |  | Year Ended December 31,
|  |  | 2025 |  |  | 2024
|  |  | (in thousands)
Audit Fees(1) |  |  | $1,880 |  |  | $1,695
Total Fees |  |  | $1,880 |  |  | $1,695

(1) | Audit fees consisted of fees for the audit of our annual financial statements and other professional services provided in connection with the statutory and regulatory filings or engagements, including fees for the review of our interim financial information, comfort letters and consents.

All fees described above were pre-approved by the audit committee.
Pre-Approval Policies and Procedures.
We have adopted a policy and procedures for the pre-approval of audit and non-audit services rendered by our independent registered public accounting firm, Deloitte. The policy generally pre-approves specified services in the defined categories of audit services, audit-related services and tax services up to specified amounts. Pre-approval may

also be given as part of the audit committee’s approval of the scope of the engagement of the independent auditor or on an individual, explicit, case-by-case basis before the independent auditor is engaged to provide each service. The pre-approval of services may be delegated to one or more of the audit committee’s members, but the decision must be reported to the full audit committee at its next scheduled meeting.
The audit committee has determined that the rendering of services other than audit services by Deloitte is compatible with maintaining the principal accountant’s independence.
Vote Required
The affirmative vote of holders representing a simple majority of the total voting rights of shareholders present in person or by proxy who (being entitled to vote) vote on the matter will be required to ratify the appointment of Deloitte as our U.S. independent registered public accounting firm, to re-appoint Deloitte as our U.K. statutory auditors and to authorize our audit committee to determine our U.K. statutory auditors’ remuneration for the year ending December 31, 2026.

APPROVAL OF OUR U.K. STATUTORY DIRECTORS’ ANNUAL REPORT ON REMUNERATION
The Companies Act requires that our directors’ remuneration report, as set forth as Annex A to this proxy statement and on pages 26 to 56 of the 2025 U.K. Annual Report, be subject to an annual advisory vote. Accordingly, we are asking shareholders to approve, on an advisory basis, the directors’ remuneration report.
Our board of directors considers that appropriate remuneration of directors plays a vital part in helping to achieve our overall objectives. We encourage shareholders to read the directors’ remuneration report. The board of directors and the remuneration committee believe that the policies and procedures as articulated in the directors’ remuneration report are effective and that as a result of these policies and procedures we have and will continue to have high-quality directors. Our U.K. statutory auditors for the year ended December 31, 2025, Deloitte, have audited those parts of the directors’ remuneration report that are required to be audited. Our board of directors has approved and signed the report in accordance with English law.
Vote Required

RESOLUTION 10
AUTHORIZATION TO MAKE POLITICAL DONATIONS OR INCUR POLITICAL EXPENDITURE
We do not make, and do not intend to make, any political donations or incur political expenditure.
However, the law in this area is widely drafted and could prohibit some activities (such as political lobbying and promoting changes in the laws, which our board of directors would consider to be in our interest) unless we have first obtained shareholder approval.
This resolution therefore seeks authority to permit political donations and political expenditure in order to authorize activities which would be within our ordinary business. The resolution also permits political donations made, and political expenditure incurred, by any of our subsidiaries. Resolution 10 caps the amount of political donations and expenditure that the Company and its subsidiaries would be permitted to make at £50,000 in each of the categories of (i) political donations to political parties and/or independent election candidates, (ii) political donations to political organisations other than political parties, and (iii) political expenditure.
Vote Required

The biographies of Mr. Kaul, Dr. Pao and Ms. Peterson are set forth above in resolutions 1, 2 and 3, respectively.
Class III Directors Continuing in Office Until the 2027 Annual General Meeting
Bahija Jallal, Ph.D. has served as our Chief Executive Officer since January 2019. Previously, she served as President of MedImmune, LLC, at AstraZeneca plc’s global biologics research and development unit, and Executive Vice President of AstraZeneca plc and a member of its senior executive team, where she worked from 2008 to 2019. Prior to joining MedImmune, Dr. Jallal was vice president, drug assessment and development, at Chiron Corporation. Dr. Jallal has served on the board of directors of Elevance Health, Inc.

Dr. Jallal received her Ph.D. in Physiology from Université de Paris VI, France and conducted her post-doctorate work in molecular biology and oncology at the Max Planck Institute for Biochemistry in Germany. We believe Dr. Jallal’s extensive experience in the biotechnology industry, leading drug research and development efforts, her educational background and her knowledge of our company as our Chief Executive Officer, qualify her to serve on our board of directors.
Professor Sir John Bell FRS, FMedSci, FREng (Hon) has served on our board of directors since March 2015. Professor Sir John Bell previously served as the Regius Professor of Medicine at Oxford University from 2002 to March 2024.

Professor Sir John Bell was involved in the founding of the Wellcome Trust Centre for Human Genetics at Oxford University, chaired the Global Health Scientific Advisory Board of the Bill and Melinda Gates Foundation until 2023, and is the Life Science Champion for the United Kingdom, advising the government on the life sciences industry. We believe his extensive scientific background and experience in the healthcare industry qualify him to serve on our board of directors.

He also served as Professor in the Department of Cancer Biology and Co-Director of the Phase I Clinical Trials Program from 2002 to 2011. In 2020, Dr. Herbst was awarded the Distinguished Public Service Award for Exceptional Leadership in Cancer Science Policy by the American Association for Cancer Research. He is also a member of the board of directors of the American Association for Cancer Research, the International Association for the Study of Lung Cancer, Shanghai Junshi Biosciences Co., Ltd. and the Thoracic Malignancy Steering Committee at the National Cancer Institute. We believe Dr. Herbst’s extensive scientific background and expertise in cancer treatment and research qualifies him to serve on our board of directors.
Professor Sir Peter Ratcliffe has served on our board of directors since November 2020.

He is also a member of European Molecular Biology Organization, a foreign honorary member of the American Academy of Arts and Sciences and a Fellow of the American Association for Cancer Research Academy. We believe Professor Ratcliffe’s extensive scientific background qualifies him to serve on our board of directors.
Corporate Governance
Board Independence
Our ADSs are listed on the Nasdaq Global Select Market. As required under the Nasdaq listing standards, a majority of the members of our board of directors must qualify as “independent,” as affirmatively determined by our board of directors. Our board of directors consults with our external counsel to ensure that the board’s determinations are consistent with relevant securities and other laws and regulations regarding the definition of “independent,” including those set forth in pertinent listing standards of Nasdaq, as in effect from time to time.
Consistent with these considerations, after review of all relevant identified transactions or relationships between each director, or any of his or her family members, and us, our senior management and our independent auditors, our board of directors has affirmatively determined that the following six directors are independent directors within the meaning of the applicable Nasdaq listing standards: Professor Sir John Bell, Dr. Herbst, Mr. Kaul, Dr. Pao, Ms. Peterson and Professor Sir Peter Ratcliffe. In addition, our board of directors has affirmatively determined that each of Ranjeev Krishana and Robert Perez was independent during the period of 2025 for which he served on the board. In making these determinations, our board of directors found that none of these directors, nominees for director or former directors had a material or other disqualifying relationship with Immunocore. Dr. Jallal was determined as not being independent by virtue of her executive leadership role with Immunocore.
Accordingly, a majority of our directors are independent as required under applicable Nasdaq rules. In making this determination, our board of directors considered the applicable Nasdaq rules and the current and prior relationships that each non-executive director has with our company and all other facts and circumstances our board of directors deemed relevant in determining their independence, including their beneficial ownership of our share capital.
Board Leadership Structure
Our board of directors has an independent chair, Professor Sir John Bell, who has authority, among other things, to call and preside over meetings of our board of directors, including meetings of the independent directors, to set meeting agendas and to determine materials to be distributed to our board of directors. Accordingly, Professor Sir John Bell has substantial ability to shape the work of our board of directors. We believe that the separation of the position of chair of our board of directors and the position of Chief Executive Officer reinforces the independence of our board of directors in its oversight of the business and affairs of our company. In addition, we believe that having an independent chair of our board of directors creates an environment that is more conducive to objective evaluation and oversight of management’s performance, increasing management accountability and improving the ability of our board of directors to monitor whether management’s actions are in the best interests of Immunocore and its shareholders. As a result, we believe that having an independent chair of our board of directors can enhance the effectiveness of our board of directors as a whole.

Role of the Board in Risk Oversight
One of the key functions of our board of directors is informed oversight of our risk management process. Our board of directors does not have a standing risk management committee, but rather administers this oversight function directly through the board of directors as a whole, as well as through various standing committees of our board of directors that address risks inherent in their respective areas of oversight. In particular, our board of directors is responsible for monitoring and assessing strategic risk exposure and our audit committee has the responsibility to consider and discuss our major financial risk exposures and the steps our management has taken to monitor and control these exposures, including guidelines and policies to govern the process by which risk assessment and management is undertaken. The audit committee also reviews and receives regular briefings concerning information security and technology risks, and monitors ongoing compliance with legal and regulatory requirements. Our nominating and corporate governance committee reviews our key enterprise risks and risk-management strategies, as well as monitors the effectiveness of our corporate governance guidelines, including whether they are successful in preventing illegal or improper liability-creating conduct, and monitors compliance with legal, regulatory and ethical requirements. Our remuneration committee assesses and monitors whether any of our compensation policies and programs has the potential to encourage excessive risk-taking.
Meetings of the Board of Directors
Our board of directors met four times during 2025. With respect to the committees of our board of directors, the audit committee met four times in 2025, the remuneration committee met five times and the nominating and corporate governance committee met three times. Each member of our board of directors attended 75% or more of the aggregate number of meetings of the board and of the committees on which they served, held during the portion of 2025 for which they were a director or committee member, with the exception of Ranjeev Krishana, who attended 71% of the meetings of the board and committees on which he served, and who has since resigned from our board of directors.
As required under applicable Nasdaq listing standards, in 2025, our independent directors met four times in regularly scheduled executive sessions at which only independent directors were present.
Information Regarding Committees of the Board of Directors
Our board of directors has three standing committees: an audit committee, a remuneration committee and a nominating and corporate governance committee. The board has adopted a written charter for each of the committees below that is available to shareholders on our website at https://ir.immunocore.com/corporate-governance/document-charters.

Director Nomination Process
We believe that an effective board of directors should be made up of individuals who collectively provide an appropriate balance of diverse occupational and personal backgrounds and perspectives and who have a range of skills and expertise sufficient to provide guidance and oversight with respect to our strategy and operations. Our board of directors and our nominating and corporate governance committee seek individuals with backgrounds and qualities that, when combined with those of our other directors, enhance the board’s effectiveness and result in a balance of knowledge, experience, and capability. Our nominating and corporate governance committee considers candidates who are recommended by its members, by other members of the board of directors, by shareholders, and by management, as well as those identified by third-party search firms retained to assist in identifying and evaluating possible candidates.
In assessing potential candidates, our board of directors and nominating and corporate governance committee will consider, among other factors, whether the candidate possesses relevant expertise to offer advice and guidance to management, has sufficient time to devote to our business and operations, demonstrates excellence in the candidate’s field; has the ability to exercise sound business judgment and is committed to represent the long-term interests of our shareholders.
Shareholder Recommendations and Nominations
Our nominating and corporate governance committee considers both recommendations and nominations for candidates to the board of directors from shareholders so long as such recommendations and nominations comply with our articles of association and applicable laws, including the rules and regulations of the SEC. Shareholders may recommend director nominees for consideration by the nominating and corporate governance committee by writing to our Company Secretary at c/o Immunocore Holdings plc, 92 Park Drive, Milton Park, Abingdon, Oxfordshire OX14 4RY, and providing evidence of the shareholder’s ownership of our ordinary shares and/or ADSs, the nominee’s name, home and business address, as well as the nominee’s detailed biographical data and qualifications for board membership, and information regarding any arrangements or understandings between the shareholder and the recommended candidate.
In accordance with our articles of association, no person (other than a director retiring by rotation or otherwise) shall be elected or re-elected as a director at any general meeting unless: (a) he or she is recommended by the board of directors; or (b) at least seven but not more than 42 clear days before the date appointed for the meeting we have received notice from a shareholder (other than the person proposed) entitled to vote at the meeting of their intention to propose a resolution for the election or re-election of that person, stating the particulars which would, if he or she were so elected or re-elected, be required to be included in our register of directors and a notice executed by that person of his or her willingness to be elected, or re-elected, is lodged at our registered office.

Executive Summary
Business Highlights
We are a commercial stage biotechnology company pioneering and delivering transformative immunomodulating medicines to radically improve outcomes for patients with cancer, infectious diseases, and autoimmune diseases. Leveraging our proprietary, flexible, off-the-shelf ImmTAX (Immune mobilizing monoclonal TCRs Against X disease) platform, we are developing a deep pipeline in multiple therapeutic areas, including clinical stage programs in oncology and infectious disease, advanced pre-clinical programs in autoimmune disease and earlier pre-clinical programs across three therapeutic areas.
In 2022, we received approval for our lead product, KIMMTRAK, for the treatment of unresectable or metastatic uveal melanoma (“mUM”) from the U.S. Food and Drug Administration (the “FDA”), the European Commission and other health authorities. KIMMTRAK is now approved in 39 countries and we have commercially launched the product in 30 countries, including the United States, Germany and France, among other territories.
KIMMTRAK is the lead product from our ImmTAX platform and was the first approved therapy in mUM. To date, we have treated over 2,000 cancer patients with KIMMTRAK, tebentafusp, and our other ImmTAX product candidates, which we believe is the largest clinical data set of any T cell engager bispecific in solid tumors and any T cell receptor (“TCR”) therapeutic.
Our clinical programs are being conducted with patients with a broad range of cancers including melanoma, ovarian, colorectal and lung, among others. We believe that these tumor types have large addressable patient populations and significant unmet need. We are progressing three late-stage clinical programs within our ImmTAC (Immune mobilizing monoclonal TCRs Against Cancer) portfolio, including KIMMTRAK and the PRAME-targeted brenetafusp.
KIMMTRAK is manufactured at facilities located in Denmark and Germany, with final packaging completed in the Netherlands. We are supporting the appropriate use of KIMMTRAK in the United States and Europe through a well-equipped and fit-for-purpose trained team that includes commercial, medical, sales, and value access team members. We utilize a hybrid commercialization model that includes an in-house sales force in the United States and in-house and contracted resources in the United States and Europe. To support our commercialization efforts, we have an exclusive multi-regional collaboration with Medison Pharma Ltd. to help seek regulatory authorization and commercialize KIMMTRAK in Canada, Australia, New Zealand, Israel, Central and Eastern Europe, South and Central America, and the Caribbean and we have entered into a distribution and commercialization agreement with Er-Kim Pharmaceuticals Bulgaria EOOD (“Er-Kim”) for commercialization of KIMMTRAK in Turkey, the Middle East, North Africa, Caucasus, and the Commonwealth of Independent States regions.

TABLE OF CONTENTS

Unlike antibody targeted immunotherapies that have a relatively small target pool, our approach relies on the power of TCRs which are naturally occurring receptors found on the surface of T cells that have the ability to target nearly all of the human proteome. Natural TCRs give T cells the ability to scan for abnormalities in nearly any cell in the body that are presented as protein fragments, or antigens, by human leukocyte antigen (“HLA”), on the cell surface. Our ImmTAX platform builds upon these natural TCRs to engineer targeted soluble and high-affinity TCRs. By engineering these TCRs through our ImmTAX platform, we are developing off-the-shelf, bispecific therapeutics, which are able to precisely target a wide range of proteins uniquely expressed by unhealthy and abnormal cells that cannot be targeted by current antibody-based immunotherapies.
Our ImmTAX bispecific therapeutics are designed to couple the targeting power of these engineered TCRs on one end with the other end displaying pre-optimized effector functions, which have the ability to drive a desired immune response at the site of the disease. This combination is designed to provide us with significant flexibility as we are able to engineer and tailor our ImmTAX therapeutics to target proteins that are specific to the disease we are trying to treat and then modulate the corresponding immune response by either boosting or inhibiting the immune system.
We will also continue pioneering immunotherapy and unlocking the full potential of our platform to generate transformative treatments for patients, by using different targeting mechanisms and immune effectors for next-generation bispecific therapies.
2025 Compensation Highlights
Our compensation program is well-structured to incentivize our leadership team to focus on the strategic objectives that, when achieved, will help to create shareholder value. To this end, we regularly evaluate and make changes to our executive compensation program to ensure that our approach aligns with shareholder interests as well as with competitive and appropriate pay practices for our industry.
During 2025, we undertook a number of activities in furtherance of our broad range of remuneration programs and policies to appropriately position us as a competitive global biopharmaceutical group, including:

• | Updated the peer group that informed our executive compensation decisions.

• | Reviewed and approved compensation for our executive officers and held executive officer base salaries flat for fiscal year 2025 (which was not reflective of their strong performance) while continuing to invest available cash in our pipeline for new products.

• | Reviewed the short-term incentives opportunities for all employees against market data and continued a global bonus structure that aligns all employees in the same job level with the same short-term incentive opportunity.

• | Introduced restricted stock units (“RSUs”) starting with our fiscal year 2025 as part of the long-term incentive plan for our named executive officers (as a percentage of the annual grant value, 70% options and 30% RSUs for our Chief Executive Officer and 60% options and 40% RSUs for our other named executive officers), other executives and all employees.

• | Continued to make grants under the equity incentive plan.

• | Analyzed share pool utilization and evergreen provision under our equity incentive plan.

• | Considered, reviewed and approved the short-term objectives for the annual bonus for fiscal year 2025, incorporating for the first time a significant weighting (67.5% of target) of only six goals focused on revenue or our portfolio as part of the much broader set goals on our corporate scorecard, to incentivize achievement of our highest priorities for fiscal year 2025.

• | Assessed performance against the short-term objectives for fiscal year 2025 and approved of the level of bonuses to be paid to our named executive officers.

• | Reviewed, evaluated, and approved employment agreements, service contracts, severance agreements, change-of-control protections, corporate performance goals and objectives, and other compensatory arrangements of the executive officers and other senior management and adjusted remuneration, as appropriate.

• | Discussed but decided not to adopt, as in past years, stock ownership guidelines and performance equity awards given our stage as a public company and the practices of our peers.

TABLE OF CONTENTS

Compensation Program Objectives, Philosophy and Elements of Compensation
The main objectives of our executive compensation program are to:

• | Motivate, attract and retain highly qualified executives who have the potential to support our growth.

• | Create a competitive, fair, reasonable and balanced compensation program that rewards executives’ performance and contributions to our short- and long-term business results, while closely aligning the interests of the executives with those of shareholders.

• | Emphasize pay for performance, with a program that aligns executive incentives to shareholder value creation.

We believe that our executive compensation program design features accomplish the following:

• | Provide base salaries consistent with each executive’s responsibilities so that they are not motivated to take excessive risks to achieve a reasonable level of financial security.

• | Ensure a significant portion of each executive’s compensation is tied to our future share performance, thus aligning their interests with those of our shareholders.

• | Utilize equity compensation and vesting periods for equity awards that encourage executives to remain employed and focus on sustained share price appreciation.

• | Adopt a mix between cash (fixed and at-risk) and equity compensation designed to encourage strategies and actions that are in our short-term and long-term best interests.

To achieve our compensation objectives, we historically have provided our executive officers, including our named executive officers, with a compensation package consisting of the following elements:

Element of Compensation |  |  | Objectives |  |  | Key Features
Base Salary (fixed cash) |  |  | Provides financial stability and security through a fixed amount of cash for performing job responsibilities. Set at a level to attract and retain executives at a caliber necessary to drive our success. |  |  | Generally reviewed annually at the beginning of the year and determined based on a number of factors (including role with us, experience, skills, external market conditions, our salary and pay structures, individual performance, internal equity, retention) and by reference to market and peer group data provided by our independent compensation consultant.
Performance Bonus (at-risk cash) |  |  | Motivates and rewards for attaining rigorous annual corporate performance goals that relate to our key business objectives. Supports our corporate strategy and business plan by linking executive performance to pay. |  |  | Target bonus amounts, calculated as a percentage of base salary, are generally reviewed annually at the beginning of the year and determined based upon positions that have similar impact on the organization and competitive bonus opportunities in our market. Bonus opportunities are dependent upon the achievement of specific corporate performance objectives, generally determined by the remuneration committee and board of directors and communicated at the beginning of the year. Actual bonus amounts earned are determined after the end of the year, based on achievement of the designated corporate performance objectives, and the remuneration committee’s overall assessment of corporate performance. The remuneration committee may further consider individual performance ratings and overall individual performance for the fiscal year when determining payout amounts. Bonus is discretionary and executives must be employed in good standing to be eligible to receive a bonus. The Chief Executive Officer’s bonus is capped at 150% of salary.

TABLE OF CONTENTS

Element of Compensation |  |  | Objectives |  |  | Key Features
Long-Term Incentive (at-risk equity) |  |  | Motivates executives who make important contributions by providing equity ownership opportunities. Rewards for long-term performance and aligns executives’ interests with shareholder interests and changes in shareholder value. Attracts highly qualified executives and encourages their continued employment over the long-term. |  |  | Annual equity opportunities are generally reviewed and determined annually at the beginning of the year or as appropriate during the year for new hires, promotions, or other special circumstances, such as to encourage retention, or as a reward for significant achievement. Individual grants are determined based on a number of factors, including current corporate and individual performance, outstanding equity holdings and their retention value and total ownership, historical value of our shares, internal equity amongst executives, other elements of compensation, and market and peer group data provided by our independent compensation consultant. To date, equity awards have been provided in the form of share options and, starting with fiscal year 2025, RSUs.

In evaluating our executive compensation policies and programs, as well as the short-term and long-term value of our executive compensation plans, we consider both the performance and skills of each of our executives, as well as the compensation paid to executives in similar companies with similar responsibilities. We focus on providing a competitive compensation package which provides significant short-term and long-term incentives for the achievement of measurable corporate objectives. We believe that this approach provides an appropriate blend of short-term and long-term incentives to maximize shareholder value.
We do not have any formal policies for allocating compensation among salary, performance bonus awards and equity grants, short-term and long-term compensation or among cash and non-cash compensation. Instead, the remuneration committee uses its judgment to establish a total compensation program for each named executive officer that is a mix of current, short-term incentive and long-term incentive compensation, and cash and non-cash compensation, that it believes is appropriate to achieve the goals of our executive compensation program and our corporate objectives. However, a significant portion of the named executive officers’ target total direct compensation is comprised of performance-based bonus opportunities and long-term equity awards, in order to align the executive officers’ incentives with the interests of our shareholders and our corporate goals.
In making executive compensation decisions, the remuneration committee generally considers each executive officer’s target total direct compensation, which consists of base salary, target bonus opportunity and long-term equity awards (valued based on an approximation of grant date fair value).
Governance Practices
The remuneration committee regularly reviews best practices in executive compensation and uses the following guidelines to design our executive compensation programs:

What We Do |  |  | What We Don’t Do
✔ Align executive compensation with shareholder interests ✔ Pay-for-performance philosophy and culture ✔ Majority of pay “at risk” and tied to our performance and objectives ✔ “Double-trigger” change-in-control provisions ✔ Maintain clawback policy |  |  | ✘ No hedging of our stock ✘ No pledging of our stock ✘ No guaranteed annual bonuses ✘ No backdating of share option awards ✘ No supplemental executive retirement plans ✘ No excessive executive perquisites

How We Determine Executive Compensation
Role of Our Remuneration Committee, Management and the Board
The remuneration committee is appointed by our board of directors to assist with the board’s oversight responsibilities with respect to our compensation and benefit plans, policies and programs, administration of our equity plans and its responsibilities related to the compensation of our executive officers, directors, and senior management, as appropriate.

TABLE OF CONTENTS

The remuneration committee is primarily responsible for establishing and reviewing our overall compensation strategy and policies. The remuneration committee meets periodically throughout the year, typically five times or more, to, among other responsibilities, manage and evaluate our executive compensation program, and generally determines the principal components of compensation (base salary, performance bonus awards, and equity awards) for our executive officers on an annual basis; however, decisions may occur at other times for new hires, promotions or other special circumstances as our remuneration committee determines appropriate. The remuneration committee does not delegate authority to approve executive officer compensation. The remuneration committee’s annual executive compensation decisions are typically made during a remuneration committee meeting in the first quarter of the year.
Our remuneration committee works with and receives information and analyses from management, including within our legal, finance, and human resources departments, and our Chief Executive Officer, and considers such information and analyses in determining the structure and amount of compensation to be paid to our executives, including our named executive officers. Our Chief Executive Officer evaluates and provides to the remuneration committee executive officer performance assessments and management’s recommendations and proposals regarding executive officer compensation programs and decisions affecting base salaries, performance incentives, equity compensation, and other compensation-related matters outside of the presence of any other named executive officers. However, our remuneration committee retains the final authority to make all compensation decisions. While the Chief Executive Officer discusses her recommendations with the remuneration committee for executives other than herself, she does not participate in the deliberations concerning, or the determination of her own compensation.
From time to time, various other members of management and other employees as well as outside advisors or consultants may be invited by the remuneration committee to make presentations, provide financial or other background information or advice or otherwise participate in remuneration committee or board of directors’ meetings.
Members of management, including our Chief Executive Officer, may attend portions of our remuneration committee’s meetings; as noted above, however, our Chief Executive Officer is not present during decisions regarding her own compensation.
Role of Independent Compensation Consultant
For purposes of evaluating 2025 compensation for each of our executive officers and making 2025 compensation decisions, we retained Aon Human Capital Solutions practice, a division of Aon plc (“Aon”), an independent compensation consultant, to assist the remuneration committee in reviewing our compensation programs and to ensure that our compensation programs remain competitive in attracting and retaining talented executives.
During fiscal year 2025, Aon advised the remuneration committee on compensation matters related to the executive and director compensation structure. In fiscal year 2025, Aon assisted with, among other things:

• | conducting an executive market pay analysis;

• | developing a group of peer companies to use as a reference in making executive compensation decisions;

• | evaluating current executive pay practices and considering alternative compensation programs; and

• | reviewing our director compensation policies and practices.

The remuneration committee has the sole authority to engage and terminate Aon’s services, as well as to approve its compensation. Our independent compensation consultant makes recommendations to the remuneration committee but has no authority to make compensation decisions on behalf of the remuneration committee or the Company. Aon reported to the remuneration committee and had direct access to the chairperson and the other members of the remuneration committee. Beyond data and advice related to executive and director compensation matters, and the Company’s purchase of general compensation data and support as our global employee benefits broker, Aon did not provide other services to us in fiscal year 2025, and that no conflict of interest exists that would prevent the compensation consultant from serving as an independent consultant to the remuneration committee.
The remuneration committee has analyzed whether the work of Aon as the compensation consultant raised any conflict of interest, considering relevant factors in accordance with SEC guidelines. Based on its analysis, our remuneration committee determined that the work of Aon and its individual compensation advisors has conformed to the independence factors and guidance provided by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, the SEC and the Nasdaq listing standards.

TABLE OF CONTENTS

Use of Competitive Market Compensation Data
The remuneration committee believes that it is important when making compensation decisions to be informed as to the current practices of comparable public companies with which we compete for top talent. To this end, the remuneration committee works annually with our independent compensation consultant to review and amend the list of our peer group companies to be used in connection with assessing compensation practices and pay levels. The remuneration committee believes that the peer and market data provided by our independent compensation consultant is helpful in determining market-competitive compensation for our executives but does not tie any pay elements directly to specific benchmarks. Instead, the remuneration committee considers peer data as part of a market-check analysis that is used in conjunction with its assessments of numerous other factors, as noted under “Factors Used in Determining Executive Compensation” below.
Fiscal Year 2025 Peer Group
In September 2024, with recommendations from Aon, the remuneration committee determined the group of companies that would be appropriate peers for fiscal year 2025 compensation decisions, based on the following criteria:

• | Stock Exchange: We focused on companies that are publicly traded on either the Nasdaq Stock Market, New York Stock Exchange or London Stock Exchange;

• | Sector & Geography: We focused on biotechnology or pharmaceuticals companies that are headquartered in the United States or United Kingdom;

• | Employee Size: We focused on companies with a headcount ranging from 1/3 to three times our then-current headcount (between 175 to 1,500 full-time employees);

• | Market Capitalization: We focused on companies with a market capitalization representing roughly 1/3rd to three times our then-current market capitalization (between $600 million to $6.0 billion); and

• | Revenue: We focused on companies with annual revenue below $800 million (compared to our approximately $300 million in then-projected revenue as a rapidly growing, newer commercial company).

The peer group of companies that the remuneration committee referenced for the purpose of informing executive compensation decisions for fiscal year 2025 is listed below:

Amicus Therapeutics (FOLD) |  |  | Bicycle Therapeutics (BCYC) |  |  | Legend Biotech (LEGN)
Apellis Pharmaceuticals (APLS) |  |  | Blueprint Medicines (BPMC) |  |  | Mirium Pharmaceuticals (MIRM)
Arcus Biosciences (RCUS) |  |  | Galapagos NV (GLPG) |  |  | Revolution Medicines (RVMD)
Arrowhead Pharmaceuticals (ARWR) |  |  | IDEAYA Biosciences (IDYA) |  |  | TG Therapeutics (TGTX)
Arvinas (ARVN) |  |  | Immatics (IMTX) |  |  | Vir Biotechnology (VIR)
Axsome Therapeutics (AXSM) |  |  | Intra-Cellular Therapies (ITCI) |  |  | Xencor (XNCR)
Beam Therapeutics (BEAM) |  |  | Ionis Pharmaceuticals (IONS) |  |  |

When determining the peer group used to inform fiscal year 2025 compensation decisions, companies included in the prior 2024 peer group were removed if they no longer met the criteria established by the remuneration committee as set forth above.
Shareholder Say-on-Pay Vote
Because we became a United States domestic issuer under SEC and Nasdaq rules effective January 1, 2024, our shareholders will have their second opportunity to cast a non-binding advisory vote (“say-on-pay vote”) to approve our named executive officers’ compensation at the AGM. At our 2024 AGM of shareholders, our shareholders approved, on a non-binding advisory basis, the compensation of our named executive officers; the proposal was supported by approximately 85% of the total votes cast. The remuneration committee reviewed the advisory vote results and, based on the strong level of support, determined that no significant changes to our executive compensation program were necessary for fiscal year 2025 as a result of the advisory vote results. However, we intend to continue to consider the outcome of our annual say-on-pay votes and our shareholders’ views when making compensation decisions regarding our named executive officers.

TABLE OF CONTENTS

Factors Used in Determining Executive Compensation
The remuneration committee sets the compensation of our executive officers at levels it determines to be competitive and appropriate for each executive officer, using the professional experience and judgment of remuneration committee members. Pay decisions are not made by use of a formulaic approach or benchmark. Instead, the remuneration committee considers numerous factors when setting executive pay levels, including market and peer data provided by our independent compensation consultant; a review of industry survey data; employee knowledge, skill, and experience; individual performance and contribution; scope of current and expected future responsibilities and any retention concerns.
Elements of Our Fiscal Year 2025 Executive Compensation Program
Base Salaries
The base salaries of our named executive officers are an important part of their total compensation package and are intended to provide a fixed component of compensation reflecting the executive’s skill set, experience, role and responsibilities. In February 2025, the remuneration committee reviewed the base salaries of our named executive officers. The remuneration committee determined to hold base salaries flat for fiscal year 2025, not as a reflection of each named executive officer’s performance, but instead to invest those funds in our robust pipeline for new products. The fiscal year 2025 base salaries of our named executive officers which became effective March 1, 2025, are reflected below.

Named Executive Officer |  |  | 2025 Base Salary |  |  | Percentage Increase from Fiscal Year 2024 Base Salary(3)
Bahija Jallal |  |  | $765,000 |  |  | N/A
Travis Coy(1) |  |  | $500,000 |  |  | N/A
David Berman |  |  | $540,000 |  |  | N/A
Tina St. Leger(2) |  |  | $374,946 |  |  | N/A

(1) | Mr. Coy joined the Company on January 1, 2025, and, therefore, was not eligible for a base pay adjustment for fiscal year 2025.

(2) | Ms. St. Leger’s base salary is paid in British Pounds. This amount represents the approximate dollar value of her base salary converted to United States Dollars using the British Pound to United States dollar exchange rate of 1.3156, which represents an average for fiscal year 2025.

(3) | Given that the Company makes base salary changes effective March 1 of each year, while each named executive officer’s annualized base salaries did not change from 2024 to 2025, the actual pay each received in 2025 was slightly higher than in 2024 as they did not receive updated salary for the full 2024 fiscal year.

Annual Performance Bonuses
The annual performance cash bonuses for our named executive officers are tied to achievement of our goals and objectives as set forth in the corporate scorecard for the relevant fiscal year. We develop our corporate scorecard each year based upon our performance goals and strategic priorities for the upcoming year. This corporate scorecard applies to our named executive officers and to all our other employees who are eligible for annual performance cash bonuses. Each eligible employee has a target annual performance incentive opportunity that corresponds to achievement of 100% of the performance goals comprising the corporate scorecard. Annually, the corporate performance metrics and overall scorecard are approved by the Board of Directors and adopted by the remuneration committee and communicated to each participant. Following the end of the year, the remuneration committee determines the extent to which the prior year’s corporate scorecard metrics were met, whether any adjustments for individual performance should be made, and incentive payments are made as soon as practicable thereafter. Pursuant to our executive director remuneration policy, our Chief Executive Officer’s performance bonus amount is capped at 150% of base salary.

TABLE OF CONTENTS

2025 Target Amounts
In January 2025, the remuneration committee reviewed each of our named executive officer’s target bonus percentages. Following on a review of applicable market and peer group data provided by our independent compensation consultant, an assessment of individual performance and an analysis of each individual’s target total cash compensation, the remuneration committee determined that the 2025 target bonus percentages remained appropriate for each of the named executive officers. Each named executive officer’s target bonus as a percentage of annual base salary is reflected below.

Named Executive Officer |  |  | 2025 Target Bonus Percentage (as a % of Base Salary)
Bahija Jallal |  |  | 75%
Travis Coy |  |  | 40%
David Berman |  |  | 40%
Tina St. Leger |  |  | 40%

2025 Corporate Scorecard Design and Achievement
For 2025, our corporate scorecard was comprised of performance objectives in three categories: TCR innovation metrics, business growth metrics and workplace improvement metrics. However, for the first time, the Company set six goals as its highest priority alongside the broader goals on its corporate scorecard (five in TCR innovation and one in business growth) to be weighed collectively as 67.5% of each named executive officer’s target bonus opportunity. The goals summarized below for each metric were selected by the remuneration committee based on the remuneration committee’s determination that each was important for our short- and long-term success. The remuneration committee set threshold (75% achievement for partially meeting the goal), target (100% achievement for meeting the goal) and maximum (150% achievement for exceeding the goal) performance levels for each goal. When it approved the 2025 performance objectives, the remuneration committee believed that achievement of target performance would be reasonably challenging based upon industry-wide conditions and our internal forecasts at the time. Our 2025 corporate scorecard and the relevant performance levels are summarized, for market factors and competitive reasons, below. The summary of our annual performance bonus design below includes the level of detail we believe we can disclose without creating competitive harm for the Company.

Metric |  |  | Weight |  |  | Goals |  |  | Achievement |  |  | Weighted Achievement
Lead in TCR Innovation |  |  | 63% |  |  | Goals focused on executing our clinical trials, building our pipeline for new products, completing regulatory submissions, high impact publications and other related matters |  |  | 113% |  |  | 70.9%
Grow the Business |  |  | 28% |  |  | Goals pertaining to commercial and other matters, including related to expanding access to our product, governmental affairs, sales, cash and operating expense targets, investor relations and business development |  |  | 137% |  |  | 38.3%
Be the Best Workplace |  |  | 9% |  |  | Goals related to recruiting, employee engagement, compliance, workforce planning, culture and other employee matters |  |  | 111% |  |  | 10.0%
|  |  |  |  |  | Initial Calculated Achievement |  |  | 119.2%
|  |  |  |  |  | Adjusted Achievement (See Below) |  |  | 120.0%

TABLE OF CONTENTS

The remuneration committee assesses corporate performance goal achievement each fiscal year. In January 2026, the remuneration committee assessed 2025 performance against the corporate scorecard and initially determined that the goals were achieved at 119.2%, as summarized in the table above. However, in light of solid achievement of specific corporate goals, including those noted in the table below, the remuneration committee approved a very slight lift in the overall achievement percentage to 120.0%, which the remuneration committee determined was appropriate to reward the hard work and accomplishments across our entire company.

Metric |  |  | Goal |  |  | Achievement
Lead in TCR Innovation (63%) |  |  | Various detailed goals around delivering on our pipeline |  |  | Goals Exceeded: • Initial multiple ascending dose data for HIV functional cure candidate presented in an oral presentation at CROI 2025 • Dose selection for PRISM MEL Phase 3 trial achieved in advance of stretch goal • Early leads for new targeted therapies identified for further consideration in 2026 Goals Achieved: • Phase 1 data for hepatitis B candidate presented at AASLD’s The Liver Meeting • Enrollment target met in Phase 1/2 ovarian and lung brenetafusp
| Deliver high impact publications and high quality publications/presentations |  |  | Goal Exceeded: Delivered above goals for high impact and high quality publications/presentations
Grow the Business (28%) |  |  | Increase KIMMTRAK net sales and reach more patients (via community settings in US, new market launches ex-US) Achieve year-end operating expenses and cash position in line with board of directors’ approved budget/forecast target Launch KIMMTRAK in five additional countries |  |  | Goal Exceeded: $400 million in net sales for 2025 Goal Achieved/Exceeded: Year-end operating expenses were within forecasted target and year-end cash of $846 million exceeded target Goal Achieved: Launched in a total of 30 countries as of the end of fiscal year 2025
Be the Best Workplace (9%) |  |  | Maintain: external engagement with web site bounce rate, HR externally promoted recruitment campaign average engagement rate, and average clinical trial click-through-rate Ensure learning and development opportunities are available/established for employees |  |  | Goal Exceeded: Achieved above targets set for goals Goal Achieved: Deployed LinkedIn Learning, continued strong feedback on Management Development Programme with two additional manager capability development modules

In approving individual annual performance bonuses, the remuneration committee also considered each named executive officer’s (other than Dr. Jallal’s) individual performance rating and overall individual contributions towards our achievement of the corporate objectives for the fiscal year. The table below reflects the applicable modifier that the remuneration committee applied to each named executive officer’s annual incentive payment based on the 2025 individual performance.
41

TABLE OF CONTENTS

Each named executive officer received the following bonus payment for fiscal year 2025 Company and individual performance:

Named Executive Officer |  |  | Incentive Amount Based on Scorecard as Percent of 2025 Target |  |  | Individual Performance Modifier |  |  | 2025 Incentive Amount Paid
Bahija Jallal |  |  | 120% |  |  | N/A(1) |  |  | $688,500
Travis Coy |  |  | 120% |  |  | 104% |  |  | $250,000(2)
David Berman |  |  | — |  |  | — |  |  | $216,000(3)
Tina St. Leger |  |  | 120% |  |  | 100% |  |  | $179,974(4)

(1) | Over the last three fiscal years, the remuneration committee has formalized an objective, numeric methodology for calculating the annual performance bonus achievement. Each of those years, the remuneration committee did not apply an individual performance modifier to Dr. Jallal’s bonus achievement. Instead, Dr. Jallal’s bonus payment was determined solely based on the approved corporate scorecard achievement (after any adjustment for overall Company performance by the remuneration committee).

(2) | Mr. Coy’s individual bonus multiplier was driven by his contributions to the Company over fiscal year 2025, including resulting in each the three metrics under the bonus program achieving substantially above 100% of target performance.

(3) | Dr. Berman is eligible for a fiscal year 2025 bonus pursuant to the terms and conditions of his agreement with the Company. The remuneration committee approved payout of the bonus at 100% of target. See “Other Features of Our Compensation Program” below for a description of the agreement.

(4) | Ms. St. Leger’s incentive payment is paid in British Pounds in accordance with her agreement with the Company. See “Other Features of Our Compensation Program” below for a description of the agreement. This amount represents the approximate dollar value of her base salary converted to United States Dollars using the British Pound to United States dollar exchange rate of 1.3156, which represents an average for fiscal year 2025.

Equity Compensation
In connection with our initial public offering (“IPO”), we adopted the 2021 EIP, under which we may grant equity-based incentive awards to directors, employees (including our executive officers) and our affiliates’ consultants. We believe that our ability to grant equity awards is a valuable and necessary compensation tool that aligns the long-term interests of our executive officers with the financial interests of our shareholders and is therefore a key aspect of our pay-for-performance program. The remuneration committee believes that share options are inherently performance-based and automatically link executive pay to shareholder return, as the value realized, if any, from an award of share options is dependent upon, and directly proportionate to, future appreciation in our share price. Regardless of the reported value in the Summary Compensation Table, our named executive officers will only receive value from their share option awards if the market price of our ADSs increases above the market price of our ADSs at the time of grant and remains above such price as the share options continue to vest.
In fiscal year 2025, we approved equity awards to our named executive officers in the form of share options and RSUs. The remuneration committee used its subjective judgement to determine the amounts it believed were appropriate for each named executive officer, weighing the following factors: the executive’s target total direct compensation, current corporate and individual performance, outstanding equity holdings and their retention value and total ownership, historical value of our ordinary shares, internal equity amongst executives and market and peer group data provided by our independent compensation consultant. The share options will vest over a four-year period, with 25% of the shares subject to each award vesting on the first anniversary of the grant date and the remaining 75% vesting in equal quarterly installments over the following 36 months, subject to continued service through the applicable vesting date. The RSUs will vest 25% on each of the first four anniversaries of the grant date, subject to continued service through the applicable vesting date.
The following table sets forth the share options and RSUs granted to our named executive officers in fiscal year 2025:

Named Executive Officer |  |  | Share Options Granted |  |  | RSUs Granted
Bahija Jallal |  |  | 405,824 |  |  | 95,270
Travis Coy |  |  | 274,033(1) |  |  | —
David Berman |  |  | 129,518 |  |  | 47,297
Tina St. Leger |  |  | 23,212 |  |  | 8,476

(1) | Represents Mr. Coy’s sign-on share option award upon joining as the Company’s new CFO on January 1, 2025. Because of his hire date, he was not eligible for an annual equity award in addition to his sign-on equity award for fiscal year 2025.

42

TABLE OF CONTENTS

It is important to note that the remuneration committee annually assesses the appropriate equity vehicle and design for its named executive officers. Specifically, this has included a discussion around the use of awards tied to the achievement of certain performance conditions (“Performance Awards”). We understand that certain investors would recommend that a portion of the annual equity grants made to the named executive officers be in Performance Awards. However, Performance Awards must be introduced at the right time when they can drive the right behaviors. Given we became a public, newly commercial stage biotechnology company in recent years, the remuneration committee did not determine over the last three years was the time to introduce Performance Awards. Further, many within our peer group also continue to use stock options as opposed to Performance Awards. Therefore, the remuneration committee has continued to approve the use of share options for 2025 as a majority (by grant value) of each named executive officer’s annual equity award given that share options are inherently performance-based as described above.
We also realize that certain of our investors engage in quantitative analysis of our pay and other programs annually. Accordingly, our compensation programs have been tied to a “pay for performance” culture as our option grants, which as described above, only deliver value upon share appreciation and are closely linked to share performance. As such, pay levels will continue to be adjusted to reflect our share price and stage of development. To this end, our recent option grants have not delivered realizable value to our named executive officers.
Other Features of Our Compensation Program
Agreements with our Named Executive Officers
We have entered into employment agreements with our United States named executive officers and an employment contract with Ms. St. Leger. Each of these agreements established the named executive officer’s starting base salary, initial target annual bonus opportunity, and initial equity grant. Our named executive officers’ base salaries, annual bonus opportunities and any equity awards are reviewed annually by the remuneration committee; the amounts effective for fiscal year 2025 are described above in this Compensation Discussion and Analysis. See “Employment Arrangements with our Named Executive Officers” below for descriptions of the agreements with our named executive officers.
Severance and Change in Control Benefits
Each of our named executive officers (other than Ms. St. Leger) is employed on an “at will” basis and may be terminated at any time for any reason. Pursuant to Ms. St. Leger’s employment contract, either Ms. St. Leger or we may terminate her employment contract upon six months’ notice. We may, at our discretion, pay Ms. St. Leger an amount equivalent to her six-month base salary in lieu of this notice. Notwithstanding the foregoing, Ms. St. Leger’s employment may be terminated by us immediately for cause.
Our employment agreements or contracts, as applicable, also contain severance terms for our named executive officers. The benefits provide cash severance and certain benefit continuation in the event of termination of employment without cause (and not due to death or disability) or resignation for good reason. Our named executive officers are entitled to enhanced severance benefits, including target bonus and pro-rated bonus payments and equity acceleration, in the event of a qualifying termination or resignation that occurs in connection with a change in control.
We believe these severance benefits are consistent with those provided by our peer group and are an essential element of our overall executive compensation package due to the competitive market for executive talent in our industry. The remuneration committee believes that the severance benefits are an important element of the named executive officers’ retention and motivation and that the benefits of such severance rights, including generally requiring a release of claims against us as a condition to receiving any severance benefits, are in our best interests. Enhanced severance benefits provided in the event of a qualifying termination or resignation that occurs in connection with a change in control are also intended to eliminate, or at least reduce, the reluctance of our executive officers to diligently consider and pursue potential change in control transactions that may be in the best interests of our shareholders.
The “Potential Payments and Benefits upon Termination or Change of Control” section below describes and quantifies the severance and other benefits potentially payable to the named executive officers in further detail.
Retirement Plans
Our United States-based named executive officers are eligible to participate in a defined contribution retirement plan that provides eligible employees with an opportunity to save for retirement on a tax advantaged basis (the “401(k) plan”). Eligible employees may defer eligible compensation on a pre-tax or after-tax (“Roth”) basis, up to the
43

TABLE OF CONTENTS

statutorily prescribed annual limits on contributions under the Internal Revenue Code of 1986, as amended (the “Code”). For the 2025 plan year, we made discretionary matching contributions on a per payroll basis equal to 100% of the first 5% of eligible compensation deferred, subject to Code limits. Matching contributions are 100% vested when made to the 401(k) plan. Contributions are allocated to each participant’s individual account and are then invested in selected investment alternatives according to the participant’s directions. The 401(k) plan is intended to be qualified under Section 401(a) of the Code with the 401(k) plan’s related trust intended to be tax exempt under Section 501(a) of the Code. As a tax-qualified retirement plan, contributions to the 401(k) plan (except for Roth contributions) and earnings on those contributions are not taxable to the employees until distributed from the 401(k) plan.
Ms. St. Leger participates in our United Kingdom defined contribution retirement plan (the “retirement plan”). The retirement plan is subject to applicable statutory requirements and permits employees to defer, via a salary sacrifice arrangement, a portion of their salary to the plan each pay period, with an employer matching contribution of up to 5% of salary deferred during the pay period.
Other than the 401(k) plan and the retirement plan, our employees, including our named executive officers, do not participate in any qualified or non-qualified retirement or deferred compensation benefits.
Health/Welfare Plans
Our United States based named executive officers are eligible to participate in broad-based health and welfare benefit plans, such as medical, dental, vision, disability and life insurance, in each case generally on the same basis as other eligible employees. Ms. St. Leger is eligible to participate in our medical, dental, life, critical illness, income protection and other schemes that we may maintain from time to time for our eligible employees in the United Kingdom. We do not maintain any supplemental health and welfare plans for our named executive officers. Our remuneration committee may elect to adopt such plans in the future if it determines that doing so is in our best interests.
Perquisites
Currently, we do not view perquisites or other personal benefits as a significant component of our executive compensation program. Accordingly, we do not generally provide perquisites or other personal benefits to our executive officers, including our named executive officers, and except as generally made available to our employees, or in situations where we believe it is appropriate to assist an individual in the performance of his or her duties, to make our executive officers more efficient and effective and for recruitment and retention purposes.
However, we are a party to tax equalization agreements with Dr. Jallal, Mr. Coy and Dr. Berman, who are United States-based employees. Pursuant to the tax equalization agreements, if the executive becomes subject to tax in the United Kingdom as a result of having performed services for us in the United Kingdom, then we have agreed to pay additional, “grossed-up” amounts to the executive as necessary so that the executive receives after-tax compensation approximately equal to the after-tax compensation the executive would have received if the executive was subject to tax only in the United States. The principle of the agreements is to leave the executive in exactly the same position (i.e., no better and no worse off) as if they had not become subject to United Kingdom taxation on a portion of their income. As such, the remuneration committee does not believe it is appropriate to take into account the United Kingdom taxes paid by us under the tax equalization agreements when determining executive compensation each year.
In the future, we may provide perquisites or other personal benefits in limited circumstances, such as those described in the preceding paragraph. All future practices with respect to perquisites or other personal benefits will be approved and subject to periodic review by the remuneration committee.
Tax and Accounting Considerations
As a general matter, the remuneration committee reviews and considers the various tax and accounting implications of compensation programs we utilize. The remuneration committee believes that shareholder interests are best served if the remuneration committee retains the discretion to approve compensation arrangements that support our corporate objectives, even if an arrangement does not qualify for full or partial tax deductibility under United States or other tax law or results in adverse accounting consequences to us.
Code Section 162(m)
Under Section 162(m) of the Code (“Section 162(m)”), compensation paid to each of our “covered employees” that exceeds $1 million per taxable year is generally non-deductible unless the compensation qualifies for certain grandfathered exceptions (including the “performance-based compensation” exception) for certain compensation paid pursuant to a written binding contract in effect on November 2, 2017, and not materially modified on or after such date.
44

TABLE OF CONTENTS

Although the remuneration committee will continue to consider tax implications as one factor in determining executive compensation, the remuneration committee also looks at other factors in making its decisions and retains the flexibility to provide compensation for our named executive officers in a manner consistent with the goals of our executive compensation program and our best interests and the best interests of our shareholders, which may include providing for compensation that is not deductible by us due to the deduction limit under Section 162(m). The remuneration committee also retains the flexibility to modify compensation that was initially intended to be exempt from the deduction limit under Section 162(m) if it determines that such modifications are consistent with our business needs.
Code Section 409A
Section 409A of the Code (“Section 409A”) affects the manner by which deferred compensation opportunities are offered to our United States taxpayer employees and other service providers. Section 409A requires that “nonqualified deferred compensation” be deferred and paid under plans or arrangements that satisfy the requirements of the statute with respect to the timing of deferral elections, timing of payments and certain other matters. Failure to satisfy these requirements can expose United States taxpayer employees and other service providers to accelerated income tax liabilities, penalty taxes and interest on their vested compensation under such plans. Accordingly, as a general matter, it is our intention to design and administer our compensation and benefits plans and arrangements for all of our U.S taxpayer employees and other service providers, including our named executive officers, so that they are either exempt from, or satisfy the requirements of, Section 409A.
Code Section 280G
Section 280G of the Code (“Section 280G”) disallows a tax deduction with respect to excess parachute payments to certain executives of companies which undergo a change of control. In addition, Section 4999 of the Code imposes a 20% excise tax on the individual with respect to the excess parachute payment. Parachute payments are compensation linked to or triggered by a change of control and may include, but are not limited to, bonus payments, severance payments, certain fringe benefits, and payments and acceleration of vesting from long-term incentive plans including share options and other equity-based compensation. Excess parachute payments are parachute payments that exceed a threshold determined under Section 280G based on the executive’s prior compensation. In approving the compensation arrangements for our named executive officers, the remuneration committee considers all elements of the cost to us of providing such compensation, including the potential impact of Section 280G. However, the remuneration committee may, in its judgment, authorize compensation arrangements that could give rise to loss of deductibility under Section 280G and the imposition of excise taxes under Section 4999 when it believes that such arrangements are appropriate to attract and retain executive talent.
Currently, if any severance payment or benefit received from the Company by Dr. Jallal, Mr. Coy or Dr. Berman would constitute a parachute payment within the meaning of Section 280G and subject to the excise tax imposed by Section 4999 of the Code, then such payments or benefits would be reduced to either (1) the largest portion of the payment that would result in no portion of the payment being subject to such excise tax or (2) the largest portion, up to and including the total, of the payment, whichever amount, after taking into account all applicable federal, state, foreign and local employment taxes, income taxes, and the excise tax, results in Dr. Jallal, Mr. Coy or Dr. Berman, respectively, receiving, on an after-tax basis, the greater economic benefit notwithstanding that all or some portion of the payment may be subject to such excise tax. None of our named executive officers have been provided with 280G gross-up arrangements.
Accounting for Share-Based Compensation
We follow the Financial Accounting Standards Board’s Accounting Standards Codification Topic 718 (“ASC Topic 718”) for our share-based compensation awards. ASC Topic 718 requires companies to calculate the grant date “fair value” of their share-based awards using a variety of assumptions. ASC Topic 718 also requires companies to recognize the compensation cost of their share-based awards in their income statements over the period that an employee is required to render service in exchange for the award. Grants of share options under our equity incentive award plans are accounted for under ASC Topic 718. The remuneration committee considers the accounting implications of significant compensation decisions, especially in connection with decisions that relate to our equity award programs. As accounting standards change, we may revise certain programs to appropriately align accounting expenses of our equity awards with our overall executive compensation philosophy and objectives.

Other Compensation Policies and Practices
Equity Grant Timing
From time to time, we grant share options and/or RSUs (“Equity Awards”) to our employees, including the named executive officers. Historically, we have granted new-hire Equity Awards on or soon after a new hire’s employment start date and annual employee Equity Awards in the first quarter of each fiscal year. Our typical practice is to grant annual employee Equity Awards on or around the 17th day of the month in which the Equity Awards are approved. Also, each non-executive director receives an automatic share option upon his or her election or appointment to the board and an annual share option at the close of business on the day of each of our annual general meetings, pursuant to the non-executive director remuneration policy, as further described under the heading, “Non-Executive Director Remuneration Policy” above. We do not otherwise maintain any written policies on the timing of awards of share options, share appreciation rights, or similar instruments with option-like features. The remuneration committee generally does not take material non-public information (“MNPI”) into account when determining the timing of awards and it does not seek to time the award of stock options in relation to the Company’s public disclosure of MNPI. We have not timed the release of MNPI for the purpose of affecting the value of executive compensation.
Compensation Recovery (“Clawback”) Policy
In October 2023, we adopted the Incentive Compensation Recoupment Policy (the “Clawback Policy”), which complies with the new Nasdaq listing standards that implement the new SEC rules under the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010. The Clawback Policy is administered by the remuneration committee.
In addition, as a public company, if we are required to restate our financial results due to our material noncompliance with any financial reporting requirements under the federal securities laws as a result of misconduct, our Chief Executive Officer and Chief Financial Officer may be legally required to reimburse our company for any bonus or other incentive-based or equity-based compensation they receive in accordance with the provisions of section 304 of the Sarbanes-Oxley Act of 2002.
Hedging and Pledging of Securities
We believe it is improper and inappropriate for any person associated with us to engage in short-term or speculative transactions involving our securities. Our directors, officers and employees are, therefore, prohibited from engaging in short sales and buying or selling puts, call options or other derivative securities with respect to our ordinary shares and ADSs.
Our Amended and Restated Insider Trading and Window Period Policy also prohibits our directors, officers, employees and consultants from purchasing any financial instruments (including prepaid variable forward contracts, equity swaps, collars and exchange funds) or otherwise engaging in transactions that are designed to or have the effect of hedging any decrease in the market value of our equity securities, whether they are granted to such individual through employee benefit plans or otherwise held by such individual.
In addition, we prohibit our executive officers, all other employees, consultants and the non-executive members of our board of directors from holding our ordinary shares in a margin account. We also prohibit pledging our ordinary shares as collateral for a loan.
Risk Assessment Concerning Compensation Practices and Policies
Our remuneration committee has reviewed our compensation policies and practices to assess whether they encourage our employees to take inappropriate risks. After reviewing and assessing our compensation philosophy, policies and practices, including the mix of fixed and variable, short-term and long-term incentives and overall pay, incentive plan structures, and the checks and balances built into, and oversight of, each plan and practice, our remuneration committee has determined that any risks arising from our compensation policies and practices for our employees are not reasonably likely to have a material adverse effect on our company as a whole. Further, our remuneration committee believes that the mix and design of the elements of executive compensation do not encourage management to assume excessive risks; the mix of short-term compensation (in the form of base salary and an annual performance bonus opportunity, if any, which is based on a variety of performance factors), and long-term compensation prevents undue focus on short-term results and helps align the interests of our executive officers with the interests of our shareholders.

Equity Compensation Plan Information
The following table summarizes our equity compensation plan information as of December 31, 2025. Information is included for equity compensation plans approved by our shareholders. We do not have any equity compensation plans not approved by our shareholders.

Equity plans not approved by shareholders |  |  | — |  |  | — |  |  | —

(1) | Includes our: (a)(1) 2020 Company Share Option Plan; (2) 2020 Non Tax-Advantaged Share Option Plan; (3) 2018 Non Tax-Advantaged Share Option Plan; (4) 2015 Company Share Option Plan; (5) 2015 Non Tax-Advantaged Share Option Plan; (6) Immunocore Limited Share Option Scheme, and (7) various standalone equity agreements (collectively, the “Legacy Arrangements”) and (b) 2021 EIP.

(2) | Includes the 2021 EIP. Options or other share awards granted under the Legacy Arrangements that are forfeited, terminated, expired or repurchased become available for issuance under the 2021 EIP, up to a maximum of 4,551,360 ordinary shares. In accordance with the terms of the 2021 EIP, the total number of our common shares reserved for issuance thereunder automatically increased on January 1st in an amount equal to 5.0% of the total number of shares of ordinary shares outstanding on December 31st of the preceding year. Accordingly, on January 1, 2026, the number of our common shares available for issuance under the 2021 EIP increased by 2,497,743 shares pursuant to this provision. These increases are not reflected in the table above.

Insurance and Indemnification
To the extent permitted by the Companies Act 2006, we are permitted to indemnify our directors and executive officers against any liability they incur by reason of their directorship. We maintain directors’ and officers’ insurance to insure such persons against certain liabilities and have entered into deeds of indemnity with each of our directors and executive officers.
Insofar as indemnification of liabilities arising under the Securities Act may be permitted to our directors, executive officers or persons controlling us pursuant to the foregoing provisions, we have been informed that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

TABLE OF CONTENTS

CEO PAY RATIO
Under rules adopted pursuant to the Dodd-Frank Act, we are required to calculate and disclose the total compensation paid to our median paid employee, as well as the ratio of the total compensation paid to the median employee as compared to the total compensation paid to our Chief Executive Officer (the “CEO Pay Ratio”).
Our median employee’s compensation in 2025 as calculated using Summary Compensation Table requirements was $117,720. Our Chief Executive Officer's compensation in 2025 as reported in the Summary Compensation Table was $10,885,268. Therefore, our CEO Pay Ratio for 2025 is approximately 92:1.
For purposes of our CEO Pay Ratio calculation, we determined that there were no changes to our employee population or to our employee compensation arrangements that we believe would significantly impact the pay ratio disclosure, allowing us to use the same median employee identified in our fiscal year 2023 proxy statement. A description of the methodology we used to identify the median employee can be found in our 2023 proxy statement.
This information is being provided for compliance purposes and is a reasonable estimate calculated in a manner consistent with the SEC rules, based on our internal records and the methodology described above. The SEC rules for identifying the median compensated employee allow companies to adopt a variety of methodologies, to apply certain exclusions and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices. Accordingly, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies have different employee populations and compensation practices and may use different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios. Neither the remuneration committee nor management of the Company used the CEO Pay Ratio measure in making compensation decisions.

PAY VERSUS PERFORMANCE
The disclosure included in this section is prescribed by SEC rules and does not necessarily align with how we or the remuneration committee view the link between our performance and named executive officer pay. For further information regarding our compensation philosophy and how we seek to align executive compensation with the Company’s performance, refer to “Executive Compensation—Compensation Discussion and Analysis.” For the most recently completed fiscal year, we did not use any “financial performance measures” as defined in Item 402(v) of Regulation S-K to link compensation paid to the named executive officers. Accordingly, we have omitted the tabular list of financial performance measures and the table below does not include a column for a “Company-Selected Measure” as defined in Item 402(v) of Regulation S-K.
Required Tabular Disclosure of Pay Versus Performance
In accordance with rules adopted by the SEC pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, we provide the following disclosure regarding executive compensation for our principal executive officer (“PEO”) and non-PEO named executive officers (“Non-PEO NEOs”) and our performance for the fiscal years listed below. The amounts set forth below under the headings “Compensation Actually Paid to PEO” and “Average Compensation Actually Paid to Non-PEO NEOs” have been calculated in a manner consistent with Item 402(v) of Regulation S-K. Use of the term “Compensation Actually Paid” is required by the SEC’s rules and as a result of the calculation methodology required by the SEC, such amounts differ from compensation actually received by the individuals and the compensation decisions described in the “Compensation Discussion and Analysis” section above.

For 2025, the Non-PEO NEOs were Mr. Coy, Dr. Berman, and Ms. St. Leger. Effective January 1, 2024, we began filing periodic reports and registration statements on U.S. domestic issuer forms. Prior to 2024, we were a foreign private issuer and were not required to disclose the annual compensation amounts for our named executive officers and were only required to disclose the PEO’s compensation in our Remuneration Report as a company organized under the laws of England and Wales. As such, we have provided our PEO’s compensation for 2021, 2022, 2023, and 2024 and only provided the 2023, 2024, and 2025 compensation for Non-PEO NEOs.

Shareholders’ Rights to Call a General Meeting
Our shareholders have the right to call a meeting of our shareholders. The Companies Act generally requires the directors to call a general meeting once we have received requests to do so from shareholders representing at least 5% of our paid-up shares entitled to vote at a general meeting. The Companies Act generally prohibits shareholders of a U.K. public limited company from passing written resolutions. However, significant shareholders would, in any case, still have the power to call a general meeting and propose resolutions. These provisions are mandatory under the Companies Act and cannot be waived by our shareholders.
Shareholder Proposals and Director Nominations for 2027 Annual General Meeting
Pursuant to the various rules promulgated by the SEC and without prejudice to the rights of a shareholder of record under the Companies Act, shareholders interested in submitting a proposal for inclusion in our proxy materials and for presentation at the 2027 annual general meeting of shareholders may do so by following the procedures set forth in Rule 14a-8 under the Exchange Act.

However, if the date of such annual general meeting is more than 30 calendar days from the date of the anniversary of the AGM, then the notice must be received by our Company Secretary a reasonable time before we begin to print and send our proxy materials.

However, if the date of the 2027 annual general meeting is changed by more than 30 calendar days from the date of the anniversary of the AGM, the notice must be received by our Company Secretary at least 45 days prior to the date we intend to distribute our proxy materials with respect to the 2027 annual general meeting. If a shareholder does not timely provide notice as described above, proxies solicited on behalf of our management for the 2027 annual general meeting will confer discretionary authority to vote with respect to any such matter, as permitted by Rule 14a-4 of the Exchange Act.
Under section 338 of the Companies Act, shareholders representing at least 5% of holders entitled to vote on a resolution at an annual general meeting may require us to include such resolution in our notice of an annual general meeting. Provided the applicable thresholds are met, notice of the resolution must be received by us at the Office of the Company Secretary, 92 Park Drive, Milton Park, Abingdon, Oxfordshire, United Kingdom, OX14 4RY at least six weeks prior to the date of the annual general meeting, or, if later, at the time notice of the annual general meeting is delivered to shareholders.

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for Proxy Materials with respect to two or more shareholders sharing the same address by delivering a single set of Proxy Materials addressed to those shareholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for shareholders and cost savings for companies.
This year, a number of brokers with account holders who are our shareholders will be “householding” the Proxy Materials. A single set of Proxy Materials will be delivered to multiple shareholders sharing an address unless contrary instructions have been received from the affected shareholders. Once you have received notice from your broker that they will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in “householding” and would prefer to receive a separate set of Proxy Materials, please notify your broker or us. Direct your written request to c/o Immunocore Holdings plc, 92 Park Drive, Milton Park, Abingdon, Oxfordshire, United Kingdom, OX14 4RY, Attn: Lily Hepworth, Company Secretary. Shareholders who currently receive multiple copies of the Proxy Materials at their addresses and would like to request “householding” of their communications should contact their brokers.

Annex A
Directors’ Remuneration Report Annual statement by the Chair of the Remuneration Committee for the year ended 31 December 2025
The information provided in this part of the Directors’ Remuneration Report is not subject to audit:
Dear Shareholder,
As the Chair of the Remuneration Committee (the “Committee”), I am pleased to present, on behalf of the board of directors (the “Board”) of Immunocore Holdings plc (the “Company” or “Immunocore”), the Directors’ Remuneration Report for the year ended 31 December 2025 (the “Report”). This is the Company’s fifth report following the successful initial public offering (“IPO”) on 5 February 2021.
The Annual Report and Consolidated Financial Statements of the Company and its subsidiaries (collectively, the “Group”), along with the Remuneration Report, will be subject to an advisory vote at the forthcoming Annual General Meeting on 27 May 2026 (the “AGM”).
During 2024, the Committee reviewed the Directors’ Remuneration Policy (the “Remuneration Policy”) and this was approved at the 2025 AGM. This Remuneration Policy is expected to remain in force until the AGM in 2028 with no requirement to vote again on the Remuneration Policy in the intervening years provided that no substantive changes are proposed.
We are a commercial stage biotechnology company pioneering and delivering transformative immunomodulating medicines to radically improve outcomes for patients with cancer, infectious diseases, and autoimmune diseases. Leveraging our proprietary, flexible, off-the-shelf ImmTAX (Immune mobilizing monoclonal TCRs Against X disease) platform, we are developing a deep pipeline in multiple therapeutic areas, including clinical stage programs in oncology and infectious disease, advanced pre-clinical programs in autoimmune disease and earlier pre-clinical programs across three therapeutic areas.
In 2022, we received approval for our lead product, KIMMTRAK, for the treatment of unresectable or metastatic uveal melanoma (“mUM”) from the FDA, the European Commission and other health authorities. KIMMTRAK is now approved in 39 countries and we have commercially launched the product in 30 countries, including the United States, Germany and France, among other territories.
KIMMTRAK is the lead product from our ImmTAX platform and was the first approved therapy in mUM. To date, we have treated over 2,000 cancer patients with KIMMTRAK, tebentafusp, and our other ImmTAX product candidates, which we believe is the largest clinical data set of any T cell engager bispecific in solid tumors and any TCR therapeutic.

• | Our clinical programs are being conducted with patients with a broad range of cancers including melanoma, ovarian, lung, and colorectal among others. We believe that these other tumor types have large addressable patient populations and significant unmet need.

• | We are progressing three late-stage clinical programs within our ImmTAC (Immune mobilizing monoclonal TCRs Against Cancer) portfolio, including KIMMTRAK and the PRAME-targeted brenetafusp.

KIMMTRAK is manufactured at facilities located in Denmark and Germany, with final packaging completed in the Netherlands. We are supporting the appropriate use of KIMMTRAK in the United States and Europe through a well-equipped and fit-for-purpose trained team that includes commercial, medical, sales, and value access team members. We utilize a hybrid commercialization model that includes an in-house sales force in the United States and contracted resources in the United States and Europe. To support our commercialisation efforts, we have entered into an exclusive multi-regional collaboration with Medison Pharma Ltd. to help seek regulatory authorization and commercialize KIMMTRAK in Canada, Australia, New Zealand, Israel, Central and Eastern Europe, South and Central America, and the Caribbean and we have entered into a distribution and commercialization agreement with Er-Kim Pharmaceuticals Bulgaria EOOD (“Er-Kim”) for commercialization of KIMMTRAK in Turkey, the Middle East, North Africa, Caucasus, and the Commonwealth of Independent States regions.
Unlike antibody targeted immunotherapies that have a relatively small target pool, our approach relies on the power of TCRs which are naturally occurring receptors found on the surface of T cells that have the ability to target nearly all of the human proteome. Natural TCRs give T cells the ability to scan for abnormalities in nearly any cell in the body that are presented as protein fragments, or antigens, by human leukocyte antigen, or HLA, on the cell surface. Our ImmTAX platform builds upon these natural TCRs to engineer soluble targeted and high-affinity TCRs. By engineering these
A-1

TABLE OF CONTENTS

TCRs through our ImmTAX platform, we are developing off-the-shelf, bispecific therapeutics, which are able to precisely target a wide range of proteins uniquely expressed by unhealthy and abnormal cells that cannot be targeted by current antibody-based immunotherapies.
Our ImmTAX bispecific therapeutics are designed to couple the targeting power of these engineered TCRs on one end with the other end displaying pre-optimized effector functions, which have the ability to drive a desired immune response at the site of the disease. This combination is designed to provide us with significant flexibility as we are able to engineer and tailor our ImmTAX therapeutics to target proteins that are specific to the disease we are trying to treat and then modulate the corresponding immune response by either boosting or inhibiting the immune system. We will also continue pioneering immunotherapy and unlocking the full potential of our platform to generate transformative treatments for patients, by using different targeting mechanisms and immune effectors for next-generation bispecific therapies.
As we move into 2026 and beyond, the Committee will continue to ensure that the Executive Director (also referred to herein as our Chief Executive Officer (“CEO”)) and senior executives at Immunocore are appropriately compensated and incentivised to deliver growth to shareholders in a long-term and sustainable manner. The Committee will seek to accomplish this by continuing to operate its established remuneration programs that: are grounded in competitive market practice, effective at driving proper executive behaviors, clearly link pay with performance, and are cost-efficient overall to shareholders.
The Global Marketplace for Talent
Immunocore is the parent company of a UK headquartered global biopharmaceutical group with operations in the UK, US and other countries in Europe. The Company intends for all regions to be areas of growth and importance both now and in the future. Given that the market for experienced directors and biopharmaceutical CEO talent, particularly in the US, is very competitive, the Committee references the US market as the leading indicator for remuneration levels and practices, supplemented by UK data. This will help attract and retain directors and motivate the superior talent needed to successfully manage the Group’s operations worldwide. Being consistent in this market view of the US as the primary benchmark for remuneration practices for our Non-Executive Directors and the Executive Director, our CEO, is key for the Group as it builds its global operations in a manner designed to deliver sustainable, long-term growth and shareholder value.
While the Committee references US market practice as the primary benchmark for both Executive and Non-Executive Director remuneration, it also takes account of UK market practice and any additional relevant local market practice when making pay decisions for Executives who reside in the UK. Immunocore will align to the local market where appropriate and align to the interests of its shareholders, but, as a global group there will be circumstances where global policies have to be adapted to meet specific jurisdiction requirements.
In taking any actions, the Committee is mindful of general UK compensation frameworks, including investor bodies’ guidance and the UK Corporate Governance Code, and has incorporated recommended practices into its remuneration programs and policies where it believes they best serve the long-term interests of shareholders.
Corporate Governance Standards
For the majority of 2025 our Board had nine members. Our Board has determined that Professor Sir John Bell, Ms. Kristine Peterson, Professor Sir Peter Ratcliffe, Dr. Roy S Herbst, Mr. Siddharth Kaul, Mr. Ranjeev Krishana, Mr. Robert Perez, and Dr. William Pao, representing eight of our nine Directors serving all or a portion of 2025, do not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these Directors is “independent” as that term is defined under Nasdaq general independence rules. For audit committee purposes, our Board has determined that each of Professor Sir Peter Ratcliffe, Mr. Siddharth Kaul, Mr. Robert Perez, Dr. Roy S Herbst, and Dr. William Pao are independent directors under Nasdaq listing rules and under Rule 10A-3 under the U.S. Securities Exchange Act of 1934, as amended. While we follow Nasdaq corporate governance rules, we also comply with UK Corporate Governance practices where applicable. Effective 1 January 2024, we were no longer a foreign private issuer within the meaning of the Exchange Act. Accordingly, for the last three fiscal years (2023 through 2025) we have been subject to United States domestic issuer rules.

TABLE OF CONTENTS

Further, the following changes to the Board’s composition occurred during 2025:

• | Mr. Travis Coy resigned from the Board, effective 1 January 2025, in connection with his becoming the Company’s Executive Vice President, Chief Financial Officer and Head of Corporate Development, as of the same date;

• | Dr. William Pao joined the Board, effective 25 February 2025;

• | Mr. Robert Perez resigned from the Board, effective 16 September 2025; and

• | Mr. Ranjeev Krishana resigned from the Board, effective 26 November 2025.

Remuneration Program Highlights
During 2025, we undertook a number of activities in furtherance of our broad range of remuneration programs and policies to appropriately position us as a competitive global biopharmaceutical group, including:

• | Updated peer group that informed our executive compensation decisions;

• | Reviewed and approved compensation for Executive Officers;

• | Reviewed the short-term incentives opportunities for all employees against market data and introduced a global bonus structure that aligns all employees in the same job level with the same short-term incentive opportunity;

• | Introduced Restricted Share Units (“RSUs”) as part of the long-term incentive plan for the CEO (as a percentage of the annual grant value, 70% options and 30% RSUs), executives and all employees;

• | Continued to make grants under the equity incentive plan, which was adopted in 2021;

• | Granted awards for employees (including the Executive Director) with market value share options under the equity incentive plan;

• | Analyzed share pool utilisation and evergreen provision under our equity incentive plan;

• | Considered, reviewed and approved the short-term objectives for the annual bonus for the financial year;

• | Assessed performance against the short-term objectives for the financial year (with, for the first time, only six of the Company’s broader corporate scorecard goals weighted a majority (67.5%) of target given their importance to the Company’s revenue and pipeline) and approved the level of bonuses to be paid to the Executive Director, as discussed below;

• | Reviewed, evaluated, and approved employment agreements, service contracts, severance agreements, change-of-control protections, corporate performance goals and objectives, and other compensatory arrangements of the executive officers and other senior management and adjusted remuneration, as appropriate; and

• | Discussed, as in past years, considerations around the adoption of stock ownership guidelines and performance equity awards, including relevant peer practices, with a focus on the right timing for both.

Total Direct Compensation
The CEO’s current total direct compensation was reviewed against the approved peer group companies and the following was agreed by the Committee.
2025 Bonus Outcome
The CEO was eligible to receive a target bonus of 75% of salary for 2025. This bonus was based entirely on corporate, strategic objectives measured through the annual bonus scorecard. Based on performance against strategic, corporate targets and the overall performance of the business over the year, 120% of the target bonus was awarded, which resulted in a payout of 90% of salary (compared to 75% for 2024). The Committee noted that the Group achieved the majority of goals and exceeded in some.
2025 Salary Outcome
The CEO requested to keep base salary flat for 2025 to increase the pool for employee salary increases. The Committee has agreed a 2025 salary increase of 0% for the CEO for this reason. This increase is not reflective of the CEO’s strong

performance. Further, the actual amount paid to the CEO in 2025 is slightly higher than for 2024, given that the Company makes base salary changes in March of each year and, thus, the annualized base salary rate only applied for 10 months of 2024.
2026 Salary Outcome
Based on competitive peer group and market data, as well as the CEO receiving no increase for 2025 for the reasons described above, the Committee approved a 6.4% increase for the CEO effective May 2026.
2026 Equity Grant
The Committee approved an equity grant to be made to the CEO of options covering 395,066 shares in 2026 with an exercise price of $32.38 and RSUs covering 88,573 shares, having a grant date target value of $9,560,000 compared to $9,400,000 for 2025. These vest in line with the Group’s equity incentive plan rules and practices set out further in this report.
Remuneration Policy
In 2022 we developed a Remuneration Policy which formalised a number of the Committee’s remuneration programs and practices. The Remuneration Policy was updated and reapproved by a binding Shareholder vote at the 2025 AGM and is expected to remain in force until the AGM in 2028 with no requirement to vote again on the Policy in the intervening years provided that no substantive changes are proposed.
Conclusion
The Committee believes the proposals put forth in this report will properly motivate our Non-Employee Directors and our CEO to deliver sustainable growth and shareholder value over the long term and do so in a responsible and cost-efficient manner.
I hope that you find the information in this report helpful, and look forward to the AGM, where we hope to have your support.

Yours sincerely, |  |  |

TABLE OF CONTENTS

Remuneration Policy for the Executive Directors
The table below sets out, for each element of pay, a summary of how Executive Director remuneration is structured and how it supports the Company’s strategy.
Base Salary

Element, purpose and link to strategy |  |  | To attract and retain new and different types of talent. Set at a level to attract and retain employees of sufficient calibre to drive the Company’s success and based on achieving the Company’s objectives that are primarily linked to the Group’s business strategies. Reflects the role in the Company, experience, skills, and external market conditions.
How it operates |  |  | Salaries are normally reviewed annually, with any increases normally taking effect from 1 March. When awarding any increase, the Committee will take into consideration: • the role in the company, experience, skills, and external market conditions; and • the Company’s salary and pay structures and general workforce increases. Salaries are benchmarked periodically against peer groups to ensure they remain competitive.
Maximum opportunity |  |  | There is no prescribed maximum annual salary or salary increase. The Committee will be guided by the market in determining salary increases but may use its discretion to award a lower increase for an Executive Director if deemed necessary. The Committee can also use its discretion to award a higher increase to recognise, for example, an increase in the scale, scope or responsibility of the role and/or take into account appropriate market factors. The Committee is also guided by the general increase for the wider workforce.
Performance-related framework |  |  | Executive Directors’ performance is a factor considered when determining any base salary increases.

Pension

Element, purpose and link to strategy |  |  | To provide employees with competitive long-term savings for their future.
How it operates |  |  | Executive Directors are eligible to participate in the Group’s pension scheme. For example, U.S.-based executives and other U.S.-based employees are eligible to participate in our Section 401(k) plan, and our U.K.-based executives and employees are eligible to participate in a U.K. defined contribution plan. If enrolled, the Group match is consistent with what is provided to other similarly situated employees enrolled in the relevant plan, subject to the terms of the retirement plan and applicable law. Levels will be reviewed annually, and the Committee may decide to change future contribution levels should the review indicate such a change is appropriate.
Maximum opportunity |  |  | Maximum opportunity under the Section 401(k) plan or other pension scheme in the jurisdiction that the Executive Director is based is set at the same level of contributions available to the wider workforce based in the same jurisdiction as the Executive Director.
Performance-related framework |  |  | Not applicable.

A-6

TABLE OF CONTENTS

Other Benefits

Element, purpose and link to strategy |  |  | Market competitive employment benefits will support the personal health and well-being of executives.
How it operates |  |  | The benefits currently available to Executive Directors include insurance at a level comparable to similarly-situated employees of the Group, as well as coverage in its Directors and Officer Liability insurance policy, each in effect from time to time. Executive Directors will be, or will continue to be eligible to participate, on the same basis as similarly- situated employees in the Group’s benefit plans in effect from time to time during their employment in accordance with the terms of such benefit plans. In addition, Executive Directors may also be provided with tax-equalisation benefits. Executive Directors may participate in any all-employee share schemes or spot-bonuses that may be operated by the Group from time to time on the same basis as similarly-situated employees in the same jurisdiction. Benefit levels and components are reviewed periodically. The Group reserves the right to change, alter, or terminate any benefit plan at its sole discretion.
Maximum opportunity |  |  | Because the value of insured and other benefits will vary year-to-year based on the cost quoted by third party providers, there is no formal maximum level of benefits provided to an Executive Director.
Performance-related framework |  |  | Not applicable.

Annual Bonus

Element, purpose and link to strategy |  |  | Supports the corporate strategy and business plan by linking executive performance to pay. Rewards the achievement of targets that support the Company’s corporate goals and delivery of the business strategy in the short term.
How it operates |  |  | Bonus payments are set by reference to a percentage of annual base salary, are normally awarded in cash (but may be awarded in shares or otherwise) and are deferrable under the U.K. defined contribution plan and under our U.S. Section 401(k) plan. Bonuses will be based upon the assessment of the Board of an Executive Director’s performance and the Company’s attainment of targeted goals over the applicable calendar year. Unless otherwise provided to the Executive Director in writing, an Executive Director must be an employee in good standing through the applicable annual bonus payment date to be eligible to receive an annual bonus, save as set out below in our policy on Termination and Loss of Office Payments. Bonus payments may be subject to malus and/or clawback under the Incentive Compensation Recoupment Policy, adopted 26 October 2023, or any other malus and/or clawback policy that may be adopted in the future.
Maximum opportunity |  |  | There is no defined maximum value for bonus, but the Committee will consider the aggregate value of any such bonus when determining what should be offered. Maximum annual bonus is currently 150% of base salary for the CEO and there is currently no intention to increase it during the life of this policy.
Performance-related framework |  |  | Each year, the Committee, in consultation with the Board, will determine the performance measures, which will be a range of targets that promote the Group’s business strategy and value creation for shareholders.

A-7

TABLE OF CONTENTS

|  |  | The annual bonus will be based upon the assessment of the Board (or a committee thereof) of the Executive Directors’ performance and the Group’s attainment of targeted goals (as established by the Board or a committee thereof in its sole discretion) for the applicable calendar year. The Committee will have the discretion to revise bonus measures annually, and the Committee also has the discretion to alter measures or to introduce new measures, based on the strategic focus of the Group at that time. If the level of payout is inconsistent with overall Group performance, the Committee has the discretion to alter the bonus outcome (including to reduce it to zero) taking into account any factors it considers relevant. This will help ensure that payouts reflect overall Group performance during the period.

Equity Incentives

Element, purpose and link to strategy |  |  | The Company adopted the 2021 Equity Incentive Plan (“EIP”) to enhance the Group’s ability to attract, retain and motivate persons who make (or are expected to make) important contributions to the Group by providing these individuals with equity ownership opportunities. The EIP facilitates share ownership to provide further alignment of the interests of Executive Directors with the interests of shareholders. Executive Directors may also hold awards granted under the predecessor plans to the EIP and may also participate in any future discretionary equity incentive plan that may be adopted from time to time to replace the EIP.
How it operates |  |  | The EIP provides for the grant of market value options, share appreciation rights, restricted share unit awards, dividend equivalents, performance awards (subject to performance conditions) and other share-based awards. Awards may be granted at such times as the Committee may determine but will generally be granted annually following the end of the financial year. Awards vest at such times and as specified in the applicable award agreement, typically being over a four-year period although the Committee retains the discretion to provide for other vesting schedules or to accelerate vesting, such as in connection with a change of control. If the participant violates the non-competition, non-solicitation, confidentiality or other similar restrictive covenant provisions of any employment contract, the right of the participant to receive these shares on vesting shall terminate immediately. The Committee maintains discretion over the type and terms of equity awards granted. The EIP is administered by the Committee or its delegate. EIP awards are not currently subject to any holding period. All awards may be subject to malus and/or clawback under the Incentive Compensation Recoupment Policy, adopted 26 October 2023, or any other malus and/or clawback policy that may be adopted in the future.

A-8

TABLE OF CONTENTS

|  |  | Any share-based entitlements granted to an Executive Director under the Company’s share plans will be treated in accordance with the relevant plan rules or any applicable agreement. Under the good leaver provisions, unvested options usually lapse at termination, but vested options can be exercised within a period as set out in the plan rules. The Committee retains the discretion to vest awards (and measure performance accordingly) on cessation and disapply time prorating; however, it is envisaged that this would only be applied in exceptional circumstances, save as set out below in our policy on Termination and Loss of Office Payments.
Maximum opportunity |  |  | There is no maximum opportunity under the EIP. However, the Committee will ensure that annual awards that are granted are guided by the market and will take account of factors such as the Executive Director’s performance, salary, other benefits and the size and value of existing awards. The Committee will also look at the position’s pay at comparators to help inform its decision.

Performance-related framework
The Committee has the discretion to choose the form of EIP awards for each year, as well as each individual grant. Currently, awards are granted subject to time-based vesting only, but the Committee may decide to introduce performance conditions for future awards and will be guided by the market in making any such decision.
Legacy Arrangements
For the duration of this Remuneration Policy, the Company will honor any commitments made in respect of current or former Directors before the date on which either: (i) the Remuneration Policy becomes effective; or (ii) an individual becomes a Director, even where not consistent with the Remuneration Policy set out in this report or prevailing at the time such commitment is fulfilled. For the avoidance of doubt, all outstanding historic awards that were granted in connection with, or prior to, listing remain eligible to vest based on their terms.
Choice of Performance Measures for Executive Directors
The choice of annual bonus performance metrics reflects the Committee’s belief that these should be appropriately challenging and tied to the delivery of key corporate and strategic targets intended to ensure that the Executive Director is incentivised to deliver across a range of objectives for which they are accountable. The Committee has retained some flexibility on the specific measures which will be used to ensure that any measures are fully aligned with the strategic imperatives prevailing at the time they are set.
The targets for the bonus scheme for the forthcoming year will be set out in general terms, subject to limitations with regards to commercial sensitivity. Short-term corporate objectives in any given year may typically include targets relating to research and development, business development and commercial revenue targets. Additional details of the targets may be disclosed when they are no longer considered to be commercially sensitive.
It is important to note that the Committee annually assesses the appropriate equity vehicle and design for its executives, including the Executive Director. Specifically, this has included a discussion around the use of awards tied to the achievement of certain performance conditions (“Performance Awards”). We understand that certain investors would recommend that a portion of the annual equity grants made to the Executive Director be in Performance Awards. However, Performance Awards must be introduced at the right time when they can drive the right behaviours. Given we became a public, newly commercial stage biotechnology company in recent years, the Committee did not determine that 2024 to 2026 was the time to introduce Performance Awards. Further, many of our peer group continue to use share options as opposed to Performance Awards for the same reasons. Therefore, the Committee approved the use of market value share options again for 2025.
Share options are inherently performance-based and automatically link executive pay to shareholder return, as the value realized, if any, from an award of share options is dependent upon, and directly proportionate to, future appreciation in our share price. We also realize that certain of our investors engage in quantitative analysis of our pay and other programs annually. Accordingly, our compensation programs have been tied to a “pay for performance” culture as our option grants, which as described above, only deliver value upon share appreciation, are closely linked to share performance. As such, pay levels will continue to be adjusted to reflect our share price and stage of development. To this end, the Company’s recent share option grants have not delivered realizable value to its named executive officers.
A-9

TABLE OF CONTENTS

The Committee will review the calibration of targets applicable to the annual bonus, and the EIP in years where performance measures apply, annually to ensure they remain appropriate and sufficiently challenging, taking into account the Company’s strategic objectives and the interests of shareholders. The Committee did approve the introduction of RSUs in 2025 for the Executive Director, executives and the broader employee population as part of the long-term incentives plan mix. Specifically, the Executive Director will, from 2025 until a further date, receive 30% of their annual equity award in RSUs and the remaining 70% will be in share options.
Remuneration Committee Discretions
The members of the Committee, including the Chairperson, will be appointed by and serve at the discretion of the Board. Vacancies on the Committee will be filled by the Board. Resignation or removal of a Committee member from the Board for any reason will automatically constitute resignation or removal from the Committee. In addition, the Committee complies with rules that are either subject to shareholder approval or by approval from the Board. These rules provide the Committee with certain discretions which serve to ensure that the implementation of the Remuneration Policy is fair, both to the individual director and to the shareholders. The Committee also has discretions to set components of remuneration within a range, from time to time. The extent of such discretions is set out in the relevant rules, the maximum opportunity or the performance metrics section of the policy table above. To ensure the efficient administration of the variable incentive plans outlined above, the Committee will apply certain operational discretions.
These include the following:

• | reviewing, evaluating, and approving employment agreements, severance agreements, change-of-control protections, corporate performance goals and objectives relating to the compensation, and other compensatory arrangements of the Company’s executive officers and other senior management and adjusting compensation, as appropriate;

• | evaluating and approving the compensation plans and programs advisable for the Company and evaluating and approving the modification or termination of existing plans and programs;

• | reviewing and approving any compensation arrangement for any executive officer involving any subsidiary, special purpose or similar entity, with consideration of the potential for conflicts of interest in such arrangements and whether the arrangement has the potential to benefit the Company; and

• | evaluating the efficacy of the Group’s compensation policy and strategy in achieving expected benefits to the Company and otherwise furthering the Committee’s policies.

If an event occurs which results in the annual bonus plan or any EIP performance conditions and/or targets being deemed no longer appropriate (e.g., material acquisition or divestment), the Committee will have the ability to make appropriate adjustments to the measures and/or targets and alter weightings, provided that the revised conditions are not materially less challenging that the original conditions. Any use of the above discretion would, where relevant, be explained in the Annual Report on Remuneration and may, as appropriate, be the subject of consultation with the Company’s major shareholders.
Differences in Remuneration Policy between the Executive Director and Other Employees
The Company operates a coherent approach to remuneration across the organisation. All employees are currently eligible to participate in the annual bonus plan and to receive equity incentive awards. Equity incentive awards encourage broad employee share ownership and alignment with the Company’s success. Although the Committee does not consult with employees directly, it is appraised of any decisions relating to pay for the broader workforce and will consider pay conditions throughout the Group when making decisions on the Executive Directors’ remuneration. In addition, the Committee has input into the pay budget for the wider employee population and has sight of equity grants below the Board.

Executive Director Employment Agreement and Payments for Loss of Office
The CEO, who is the only current Executive Director, is currently employed at-will pursuant to an employment agreement entered into with the Company’s indirect wholly owned subsidiary Immunocore LLC, effective as of 5 February 2021. The CEO’s employment may be terminated by either party at any time for any or no reason, with or without notice. Severance payments no greater than those described in this policy will be payable to her on termination. Upon termination of the employment agreement, the CEO is required to resign from all other positions within the Group. Following termination of employment, the CEO will be bound by certain post-termination covenants.
As is customary for US executives, the CEO’s remuneration is subject to a “best-after-tax” cutback for excise tax calculations under section 280G of the US Internal Revenue Code of 1986, with no tax gross-up.
The CEO is also engaged as a director of the Company pursuant to an appointment letter dated 22 January 2021. The CEO is not entitled to any additional remuneration under this appointment letter.
A copy of the contract and appointment letter may be viewed at the Company’s head office or may be requested from the Company Secretary at the AGM. The initial term of the CEO’s appointment as a director of the Company was due to end on 23 May 2024 but was renewed on that date for a further three years by approval of the Company’s shareholders.

Where a notice period applies, this will not exceed 12 months but may be accompanied by additional severance entitlements where applicable.
The remuneration the Executive Director is eligible for under her employment agreement upon leaving the Company in certain circumstances is set out in the table below. The Committee will exercise its discretion when determining amounts that should be paid to leavers, taking into account the facts and circumstances of each case.

TABLE OF CONTENTS

Additional Payments
The Committee reserves the right to make payment it considers reasonable under a settlement agreement, including payment of reimbursement of reasonable legal and professional fees, untaken holiday and any payment for the settlement of potential claims against the Group in the US, UK or other jurisdictions. Payment or reimbursement of reasonable outplacement fees may also be provided.
Approach to Recruitment and Promotions
Where it is necessary to appoint or replace an Executive Director, the Committee’s approach when considering the overall remuneration arrangements (including base salary, cash incentives, equity based awards, benefits, sign on bonus and other components) in the recruitment or promotion of a new Executive Director is to take account of the calibre, expertise and responsibilities of the individual, his or her remuneration package in their prior role and the prevailing market rate for similar roles. Remuneration will be in line with the Company’s policy and the Committee will not pay more than is necessary for a successful recruitment.
The remuneration package for a new Executive Director will be set in accordance with the terms of the Company’s approved remuneration policy in force at the time of appointment. Where necessary, the Board retains discretion to provide additional or different remuneration or benefits to recruit new Executive Directors (including but not limited to “buy-out” existing awards on such terms as the Committee may determine) or continue the employment of an existing Executive Director.
Policy on External Appointments
Except with the prior written consent of the Board, Executive Directors will not, while employed by the Company, undertake or engage in any other employment, occupation, or business enterprise. The Board, however, recognises the potential for an Executive Director to be involved in volunteering work, or serve on another board of directors, so long as such activities do not interfere in any material way or conflict with the performance of the Executive Director’s duties and responsibilities.
Remuneration Policy for Non-Executive Directors Fees and Benefits

Element, purpose and link to strategy |  |  | To attract and retain Non-Executive Directors who have a broad range of experience and skills to provide independent judgement on issues of purpose, value, and strategy for the Company. Supports the retention of Non-Executive Directors who will promote the long-term sustainable success of the Company, generating value for shareholders. We annually review the composition, skills and other qualities that the Non-Executive Directors bring to the Board.
How it operates |  |  | Non-Executive Directors’ fees (including the basic fee and fees for any additional roles) will be set forth in the Company’s Non-Executive Director Remuneration Policy as amended from time to time by the Board. The Company shall reimburse Non-Executive Directors for all reasonable and properly documented expenses in accordance with the Non-Executive Director Remuneration Policy. Non-Executive Directors may also be provided with tax-equalisation benefits and assistance with tax returns. Non- Executive Directors do not receive any pension benefits or cash in lieu thereof.
Maximum opportunity |  |  | While there is no maximum annual fee or fee increase, the Board can use its discretion to award a lower or higher fee, taking into account wider workforce experience. A higher fee or out-of-cycle additional payment could recognise an increase in the scale, scope or responsibility of the role and/or take account of relevant market movements. Actual fee levels are disclosed in the Annual Remuneration Report for the relevant financial year.
Performance-related framework |  |  | Not applicable.

TABLE OF CONTENTS

Equity Incentives

Element, purpose and link to strategy |  |  | To facilitate share ownership by Non-Executive Directors in the Company and provide alignment of the interests of the Non-Executive Directors with those of shareholders.
How it operates |  |  | Non-Executive Directors are eligible to participate in the Non-Employee Sub-Plan to the EIP. The EIP provides for the grant of market value options, share appreciation rights, restricted share unit awards, dividend equivalents, performance awards (subject to performance conditions) and other share-based awards. Further, subject to the terms of the award agreement, awards can be granted in respect of ordinary shares, American Depositary Shares (“ADS”), cash or a combination thereof. However, performance awards (subject to performance conditions) will not be issued to Non-Executive Directors. Awards vest in accordance with the vesting schedule set for the relevant award in its award agreement. The Committee maintains discretion over the type and terms of equity awards granted. Non-Executive Directors usually receive options on joining the Board and annually as part of their remuneration with phased vesting. Under normal circumstances, initial share awards vest monthly over three years and options awarded annually will usually vest upon the first anniversary of the date of grant. Vesting may be accelerated in certain circumstances, such as in connection with a change of control. Non-Executive Directors may also hold awards granted under the predecessor plans to the EIP and may also participate in any future discretionary equity incentive plan that may be adopted from time to time to replace the EIP.
Maximum opportunity |  |  | There is no maximum number of equity incentive awards that may be awarded to individuals each year. However, when reviewing award levels, account is taken of market movements in equity incentive awards, Board committee responsibilities, ongoing time commitments and the general economic environment.
Performance-related framework |  |  | Performance Awards will not be made to Non-Executive Directors. However, we believe share options are inherently performance-based and automatically link pay to shareholder return, as the value realised, if any, from an award of share options is dependent upon, and directly proportionate to, future appreciation in our share price.

Non-Executive Directors’ Terms of Engagement – Letters of Appointment
The Company has entered into appointment letters with its Non-Executive Directors. The terms of appointment for a new Non-Executive Director would be in accordance with the Remuneration Policy for Non-Executive Directors as set out in the policy table above. Newly appointed Non-Executive Directors would normally receive an initial award of market value options (but this may also take the form of restricted share units or similar securities) on the date of election or appointment, which will vest based on time only on a monthly basis over a three-year period from the date of grant, provided that the Non-Executive Director continues his or her directorship through each of the vesting dates.
A Non-Executive Director’s directorship may be terminated at any time by the Non-Executive Director or the Board giving one month’s notice in writing, or by the Company in accordance with Company Articles.

Directors’ letters of appointment are available for inspection at the Company’s registered office during normal business hours and will be available for inspection at the AGM.
While engaged by the Company, Non-Executive Directors engaged in any other employment, occupation, or business enterprise will keep the Group’s Nominations Committee informed of any changes to their status or any conflicts that emerge. The Board recognises the potential for a Non-Executive to be involved in such engagements, as well as volunteering work, or service on another board of directors, so long as such activities do not interfere in any material way or conflict with the performance of the Non-Executive Director’s duties and responsibilities.
Statement of Consideration of Employment Conditions Elsewhere in the Group
The Committee is regularly updated throughout the year on pay and conditions applying to Group employees. Where significant changes are proposed to employment conditions elsewhere in the Group, these are highlighted for the attention of the Committee. Although the Committee does not consult with employees directly, it is apprised of any decisions relating to pay for the broader workforce and will consider pay conditions throughout the Group when making decisions on Executive Directors’ remuneration.
Statement of Consideration of Shareholder Views
The Board is committed to an open dialogue with shareholders. Following each AGM, the Board will look to receive any feedback and guidance from shareholders, as well as any additional feedback and guidance from time to time throughout the year. This feedback will be incorporated into the Committee’s discussions as it develops the Company’s remuneration framework and practices for the following year. Assisted by its independent adviser, the Committee and the Board will also actively monitor developments in the expectations of institutional investors and their representative bodies.

TABLE OF CONTENTS

Notes to the compensation table:

1. | Dr. Jallal’s benefits comprise health cover, life insurance, disability cover ($22,168) and tax equalisation gross-up payments ($14,286) paid with respect to the portion of her income subject to United Kingdom taxation. Dr. Herbst and Ms. Peterson’s benefits comprise tax equalisation gross-up payments paid with respect to the portion of their income subject to United Kingdom taxation.

2. | Represents a performance-based cash bonus awarded to Dr. Jallal in connection with the achievement of 2025 annual performance milestones (paid in 2026). Dr. Jallal was assigned a target bonus expressed as a percentage of her base salary, and the target bonus amount for Dr. Jallal for 2025 and 2024 was 75%. For 2025, the Board determined to award Dr. Jallal an annual bonus of $688,500 or 120% of target (2024: $573,750 or 100% of target), as reflected in the “Annual Bonus” column of the table above.

3. | For the year ended 31 December 2025, the “Share Based Awards” column reflects the value of Dr. Jallal’s RSU grant for the year based on the product of the number of shares granted and the closing price of the Company’s shares on the grant date. This results in a significant difference in total pay included in the table for Dr. Jallal compared to 2024 as 2025 was the first year in which RSUs were granted to Dr. Jallal and other employees. For share option awards granted in the year ended 31 December 2024, the exercise price is equal to the market value of the shares on the date of the grant and therefore there is no value to disclose. Details of the share option awards granted and held are set out in the options table further below in this report. There were no performance obligations linked to the share-based awards granted during the years above.

4. | Mr. Perez and Mr. Coy were originally nominated to our Board in connection with our IPO. Both directors elected to forgo remuneration in respect of their services as non-executive directors. Mr. Coy, Mr. Perez and Mr. Krishana resigned from the Committee during 2025 on 1 January, 16 September and 26 November, respectively.

2025 Annual Bonus
In 2025, the CEO’s bonus of $688,500 (being 90% of salary), compared to $573,750 (75% of salary) in 2024, was based on corporate, strategic objectives: Lead in T cell receptor (“TCR”) Innovation (63%); Grow the Business (28%); Be the Best Workplace (9%), measured through the annual bonus scorecard.
The summary of our 2025 annual performance bonus design below includes the level of detail we believe we can disclose without creating competitive harm for the Company.

Metric |  |  | Weight |  |  | Goals |  |  | Achievement |  |  | Weighted Achievement
Lead in TCR Innovation |  |  | 63% |  |  | Goals focused on executing our clinical trials, building our pipeline for new products, completing regulatory submissions, high impact publications and other related matters |  |  | 113% |  |  | 70.9%
Grow the Business |  |  | 28% |  |  | Goals pertaining to commercial and other matters, including related to expanding access to our product, governmental affairs, sales, cash and operating expense targets, investor relations and business development |  |  | 137% |  |  | 38.3%
Be the Best Workplace |  |  | 9% |  |  | Goals related to recruiting, employee engagement, compliance, workforce planning, culture and other employee matters |  |  | 111% |  |  | 10.0%

TABLE OF CONTENTS

In January 2026, the Committee assessed 2025 performance against the corporate scorecard and initially determined that the goals were achieved at 119.2%, as summarized in the table above. However, in light of solid achievement of specific corporate goals and exceeding in some, including those noted in the table below, the Committee approved a minimal uplift in the overall achievement percentage of 120%, which the Committee determined was appropriate to reward the hard work and accomplishments across our entire company.

Metric |  |  | Goal |  |  | Achievement

TABLE OF CONTENTS

Notes to the table:

1. | Options granted during 2021 were granted at the time of our IPO. The exercise price of $26.00 is equal to the price per ADS sold in the IPO, and the awards have no performance conditions attached. The exercise price of all option awards is equal to the market value at the date of grant, and accordingly there is no value to the recipients at the point of grant. The face value of awards has been calculated by multiplying the share price at the date of grant by the number of shares subject to the award granted.

2. | Options granted to Dr. Jallal on 17 February 2025, 16 February 2024, 16 February 2023, 16 February 2022, 4 February 2021, and 30 October 2020, vest over a four-year period from the date of grant. Twenty-five percent of the shares subject to each of those awards vested on the first anniversary of the vesting commencement date, and the remaining shares vest in quarterly installments thereafter, subject to the officer’s continued service through each vesting date. The options granted on 30 October 2020 have a vesting commencement date of 1 April 2020. Twenty-five percent of the shares subject to the 30 October 2020, award vest on the first anniversary of the vesting commencement date (1 April 2021), and the remaining shares vest in quarterly installments thereafter, subject to the officer’s continued service through each vesting date

3. | The options granted to Dr. Jallal on 7 January 2019, vesting over a five-year period were modified during 2020 and immediately prior to the IPO. The incremental fair values arising on these modifications for accounting purposes were $3.84 and $5.19, respectively. Twenty five percent of the shares subject to the award vested on the second anniversary of the vesting commencement date, and the remaining shares vested in quarterly installments thereafter, subject to the officer’s continued service through each vesting date.

4. | RSUs vest 25% on each of the first through fourth anniversaries of the vesting commencement date, subject to Dr. Jallal’s continued service through each vesting date.

5. | The Non-Executive Director options vest as follows:

• | Awards Granted in 2025, 2024, 2023 and 2022: Other than for Mr. Kaul’s 2022 award (described in note 5 below) and Mr. Krishana’s 2024 award (described in note 6 below), these option awards become fully vested on the one-year anniversary of the grant date.

• | Awards Granted 2021: These annual option awards vest over a four-year period from the date of grant, with 25% of the award vesting on the first anniversary of the vesting commencement date and the remaining shares vesting in quarterly installments thereafter, subject to the director’s continued service through each vesting date.

• | Awards Granted Prior to 2021: These pre-IPO awards were fully vested on the date of grant.

6. | Represents option awards granted on appointment as a non-executive director in the year ended 31 December 2022, with the award vesting monthly over a period of three years.

7. | Represents option awards granted on appointment as a non-executive director in the year 2024 (Mr. Krishana) and 2025 (Dr. Pao), with the award vesting monthly over a period of three years.

Note: | Travis Coy and Robert Perez were originally nominated to our Board by Eli Lilly S.A. and General Atlantic, respectively, pursuant to our pre-IPO fundraising arrangements, which granted a right to each of Eli Lilly S.A. and General Atlantic to appoint an individual to our board. Both directors elected to forgo remuneration in respect of their services as non-executive directors. Further, Mr. Coy resigned from the Board, effective January 1, 2025, in connection with his joining the Company as its Executive Vice President, Chief Financial Officer and Head Corporate Development on the same date.

Payments to Past Directors and Loss of Office
No payments were made to former directors of the Company or in relation to loss of office during the year.

TABLE OF CONTENTS

Directors’ Shareholding and Share Interests
The share interests of each Director as of 31 December 2025 (together with interests held by his or her connected persons) are set out in the table below. Directors are encouraged to build up a shareholding but currently no formal shareholding requirements apply, although the Company has considered adopting requirements over the past two years but ultimately determined that it was not the right time for the Company given its historic equity vehicle of 100% share option grants and other factors. Details of share options and RSUs awarded to the CEO and Non-Executive Directors, as of 31 December 2025 are set out in the “Equity Awards” table provided earlier in this Remuneration Report.

TABLE OF CONTENTS

The information provided in this part of the Directors’ Remuneration Report is not subject to audit:
TSR Performance Graph
The graph below shows a comparison, from 5 February 2021 (the date our ADSs commenced trading on Nasdaq) through 31 December 2025, of the cumulative total return to shareholders of our ADSs relative to the Nasdaq Composite Index and the Nasdaq Biotech Index. The graph assumes that $100 was invested in each of our ADSs, the Nasdaq Composite Index and the Nasdaq Biotech Index at their respective closing prices on 5 February 2021 and assumes reinvestment of gross dividends. The share price performance shown in the graph represents past performance and should not be considered an indication of future share price performance.
Aligning Pay with Performance
2021 was the first year that the Company has prepared a Remuneration Report and as the Company was incorporated on 7 January 2021, and we do not have any historical remuneration to disclose for periods prior to 2021.

|  |  | Total remuneration $ |  |  | Annual bonus (percentage of target) |  |  | Share options/RSUs vested during the year(1)

(1) | The number of share options and RSUs vesting during each year are included on the basis that no performance-based conditions currently apply to equity awards and therefore a disclosure of the percentage permitted to vest in respect of the year is not informative.

A-24

TABLE OF CONTENTS

(2) | While the table above reflects a material increase in total remuneration compared to 2024, this is driven completely by the inclusion of RSU values for the first time in 2025. Given that the value of share option awards are not reflected in the total remuneration described above for the reasons described in this Remuneration Report, this increase does not highlight a change in comparable equity awards granted year-over-year given the equity mix now includes another equity type (i.e., RSUs).

External Directorships
The Board believes that it may be beneficial to the Company for Executives to hold certain roles outside the Company, provided that the Company’s business takes priority. Any such appointments are subject to the prior written consent of the Board, and the Director may retain any fees received. The CEO currently serves as a member of the board for Elevance Health (previously known as Anthem Inc), and Johns Hopkins University.
Percentage Change in the Remuneration of the Directors Compared to Other Employees
2021 was the first year that the Company prepared a Remuneration Report as the Company was incorporated on 7 January 2021, and we do not have any historical remuneration to disclose for periods prior to 2021.

Relative Importance of the Spend on Pay
The table below illustrates the Company’s expenditure on pay, in comparison to Group’s expenditure on research and development costs. Research and Development is the company’s principal activity and, as such, is the most appropriate metric against which to measure employee expenditure given there have been no distributions to shareholders by way of dividend or share buyback.

|  |  | 2025 ($000)(2) |  |  | 2024 ($000)(2)
Group research and development costs |  |  | 275,309 |  |  | 217,658
Total employee pay expenditure(1) |  |  | 136,775 |  |  | 120,884

(1) | Total employee pay expenditure includes wages and salaries, social security costs, GUID contributions, bonus and share-based compensation charge.

(2) | For remuneration not paid in U.S. dollars, using an exchange rate of GBP 1.00 to USD 1.3156, which represents an average for fiscal year 2025 (with conversion rates of GBP 1.00 to USD 1.2781 for 2024).

The above table reflects expenditure for the full year.

TABLE OF CONTENTS

Chief Executive Officer Pay Ratio
These ratios set out the comparison between the CEO’s remuneration and that for employees in the UK for the full years ended 31 December 2025 through 2021. 2021 was the first year that the Company prepared a Remuneration Report as the Company was incorporated on 7 January 2021, and we do not have any historical remuneration to disclose for periods prior to 2021.

The remuneration for employees in the UK workforce is based on the data used for gender pay reporting, which comprises salary and benefits as of 5 April of each applicable year and incentive payments payable in respect of the full years ended 31 December of each applicable year. Actual benefit amounts are used for the purposes of ratio in the table above. The ratios have been calculated using Method B as we believe it provides the best comparison of colleague pay with that of our CEO. For remuneration not paid in U.S. dollars, amounts in pounds sterling have been translated using an exchange rate of GBP 1.00 to USD 1.3156, which represents an average for fiscal year 2025 (with conversion rates of GBP 1.00 to USD 1.2781 and GBP 1.00 to USD 1.2400 for 2024 and 2023, respectively).
As reflected in the table above, our CEO pay ratio has not varied significantly over the last three years. Therefore, changes to the ratio are generally reflective of adjustments within our broader workforce and their applicable pay.

TABLE OF CONTENTS

Bonuses will be paid entirely in cash and will be based entirely on the achievement of operational and strategic objectives based on the company scorecard and assessed following the end of the 2026 financial year. Specific targets are commercially sensitive and therefore are not disclosed in advance. However, a description of the targets and performance against them will be disclosed in next year’s Annual Report and Accounts.

The Committee has granted an award in the first quarter of 2026 of options covering 395,066 shares with an exercise price of $32.38 and RSUs covering 88,573 shares to the CEO, Options will vest 25% after one year and in quarterly instalments thereafter, subject to continued service.

RSUs do not have an exercise price, but settlement is subject to payment of the nominal value (GBP 0.002 per share).
Non-Executive Director Fees
Non-Executive Director fees were initially reviewed and set at the time of the IPO. Fees are reviewed annually and in 2024 were reviewed against a peer group, with no changes proposed for 2025 or 2026.

The Company provides an initial, one-time equity award of market value share options to each new Non-Executive Director upon his or her election to our Board. Under normal circumstances, initial share awards vest monthly over three years. The Company intends to provide an annual equity incentive award of market value share options to each Non-Executive Director. Options awarded annually will usually vest at the earlier of (i) the one-year anniversary of the date of grant and (ii) the day immediately prior to the date of the Company’s next annual general meeting. All vesting is subject to the eligible Non-Executive Director continuing to be a Service Provider (as defined in the EIP) on each applicable vesting date. Notwithstanding the foregoing vesting schedules, for each eligible director who remains continuously a Service Provider until immediately prior to the closing of a “Change in Control” (as defined in the EIP), the shares subject to his or her then-outstanding equity awards will become fully vested immediately prior to the closing of such change in control.
Each Non-Executive Director will also be entitled to reimbursement of reasonable expenses and tax equalisation benefits.

On behalf of the Board |  |  |
