Dear Shareholder

Notice of Annual General Meeting

I am pleased to be writing to you with details of the Annual General Meeting of the Company ('AGM' or the 'Meeting') which will be held as a physical meeting at Pinnacle House, Breedon Quarry, Breedon on the Hill, DE73 8AP (what3words: hood.looks.statement) on Wednesday 29 April 2026 at 2.00pm.

Details of the resolutions to be proposed at the AGM are set out in the Notice of AGM on pages 3 to 5 of this document, with Resolutions 1 to 14 being ordinary resolutions and Resolutions 15 to 18 being special resolutions. An explanation of all the resolutions can be found on pages 6 to 9 of this document.

I have now been a member of the Board of Directors of Breedon Group plc (the 'Board') for over nine years, the last seven years as Chair. As explained last year, I remain eager to contribute to our ongoing development and am therefore seeking re-election (Resolution 6) at the forthcoming AGM. The Board fully supports my re-election and the Senior Independent Director engaged with shareholders representing over half of our issued share capital in advance of last year's AGM, during which they recognised my experience, commitment and passion for the business. Further details can be found on pages 6 and 7 of this AGM notice and on page 126 of the 2025 Annual Report and Accounts.

The purpose of the AGM is to seek shareholders' approval of the resolutions set out in the Notice of AGM. It is also an opportunity for shareholders to express their views and to ask questions of the Board. The Board is committed to open dialogue with the Company's shareholders and the AGM is an excellent means for the Board to engage with you directly.

As we appreciate some shareholders may prefer not to attend, or may be unable to attend, in person, shareholders are encouraged to submit any questions they may have for the Board in connection with the AGM in advance. A designated questions and answers facility has been created, which can be accessed through our AGM webpage www.breedongroup.com/agm. Questions must be submitted by 9.00am on Friday 24 April 2026 and the Board will endeavour to respond to relevant questions either at the AGM or by return email. Where deemed appropriate by the Board, responses will also be provided on the AGM webpage following the AGM. If shareholders require a response to a question prior to the proxy voting deadline, please ensure that the question is received by the Company by 9.00am on Wednesday 15 April 2026, in which case the Board will endeavour to respond to the shareholder by Wednesday 22 April 2026 to provide shareholders with time to consider the response ahead of the proxy voting deadline on Monday 27 April 2026.

2025 Annual Report and Accounts

If you have not asked to be sent a copy of the 2025 Annual Report and Accounts ('Annual Report and Accounts') by post, you can find it on our website at www.breedongroup.com/investors. The majority of our shareholders now receive shareholder information electronically and I would encourage shareholders who have elected to receive information from the Company in hard copy to consider opting to receive publications, including the Annual Report and Accounts, in electronic form. You can register for electronic communications at www.breedonshares.com or contact the Company's Registrar, MUFG Corporate Markets.

Voting

It is important to the Company that shareholders have the opportunity to vote on the AGM resolutions, even if they are unable to attend in person. Shareholders can submit proxies for the 2026 AGM electronically by logging on to www.breedonshares.com, via the MUFG Corporate Markets Investor Centre app or, if you hold shares in CREST, by using the CREST electronic proxy appointment service. If attending in person, please ensure that you bring your ID to gain entry or your proxy brings their ID.

The Company is committed to reducing paper and improving efficiency in its shareholder communications and therefore, you will not receive a hard copy form of proxy for the 2026 AGM. You may request a hard copy form of proxy directly from the Company's Registrar. Full details on how to vote online, use the Investor Centre app and to request and complete a hard copy form of proxy are set out on pages 10 to 11 of this document.

If you are an institutional investor, you may be able to appoint a proxy electronically via the Proxymity platform. For further information regarding Proxymity, please go to www.proxymity.io.

All proxy instructions must be received by the Company's Registrar by no later than 2.00pm on Monday 27 April 2026 (or not less than 48 hours before the time fixed for any adjourned meeting).

Recommendation

The Board considers that each of the resolutions to be put to the AGM is in the best interests of the Company and its shareholders as a whole and would promote the success of the Company. Your Board members will be voting in favour of them in respect of their own shareholdings and they unanimously recommend that you do so as well.

The results of the voting on all resolutions will be announced via the Regulatory News Service and published on our website www.breedongroup.com/investors as soon as practicable following the conclusion of the AGM.

Yours faithfully

Amit Bhatia
Chair

Breedon Group plc Notice of Annual General Meeting and explanatory notes to shareholders

Explanatory Notes

EXPLANATORY NOTES

Resolutions 1 to 14 (inclusive) are proposed as ordinary resolutions. For each of these to be passed, more than half of the votes cast must be in favour of the relevant resolution. Resolutions 15 to 18 are proposed as special resolutions. For each of these to be passed, at least three quarters of the votes cast must be in favour of the relevant resolution.

An explanation of each of the resolutions is set out below.

ORDINARY RESOLUTIONS

RESOLUTION 1: Annual Report and Accounts

The Directors are required to present to the AGM the audited accounts and the Directors' and Auditors' Reports of the Company before the shareholders for the financial year ended 31 December 2025.

RESOLUTIONS 2 AND 3: Re-appointment of Auditor and Auditor's Remuneration

The Company is required to appoint an auditor at each general meeting at which accounts are laid to serve until the next such meeting. The current appointment of KPMG LLP as the Company's auditor will end at the conclusion of the AGM and it has indicated its willingness to continue in office. The Audit & Risk Committee has evaluated the effectiveness and independence of the Company's auditor, and the Board proposes as Resolution 2 that KPMG LLP be re-appointed as auditor of the Company. Details of how the effectiveness and independence has been assessed and monitored is set out on page 118 of the Annual Report and Accounts.

It is normal practice for a company's directors to be authorised to agree how much the auditor should be paid and Resolution 3 authorises the Directors to negotiate and agree the remuneration of the auditor. Details of the remuneration paid to the Company's external auditor for 2025 can be found on page 177 of the Annual Report and Accounts.

RESOLUTION 4: Directors' Remuneration Report

The Directors' Remuneration Report, which can be found on pages 132 to 148 of the Annual Report and Accounts, comprises the Annual Statement to shareholders by the Remuneration Committee Chair and the Annual Report on Remuneration. The Annual Report on Remuneration sets out details of Directors' remuneration for the year ended 31 December 2025 and proposed implementation of the Directors' Remuneration Policy for 2026. The Company's auditor has audited those parts of the Directors' Remuneration Report required to be audited and their report may be found on pages 154 to 163 of the Annual Report and Accounts.

In accordance with section 439 of the Companies Act 2006 ("the Act"), shareholders are requested to approve the Directors' Remuneration Report. The vote is advisory and the Directors' entitlement to receive remuneration is not conditional on it.

RESOLUTION 5: Final Dividend

A final dividend of 10.25 pence per ordinary share of 1.0 pence in the Company for the year ended 31 December 2025 is recommended by the Directors. If approved, the recommended final dividend will be paid on 10 July 2026 to all shareholders whose names appear on the Company's Register of Members at 6.00pm on 29 May 2026.

RESOLUTIONS 6 TO 12: Re-election of Directors

In accordance with the UK Corporate Governance Code (the 'Code'), all of the Directors are subject to annual re-election by shareholders at the AGM irrespective of their date of appointment and length of service on the Board. Separate resolutions will be proposed for each of these re-elections.

The Directors believe that the Board has an appropriate balance of knowledge and skills and that the Non-executive Directors are independent in character and judgement. The Chair confirms that the Non-executive Directors continue to demonstrate effective performance and commitment to the role and have sufficient time to meet their responsibilities. The continued effectiveness of the Board, its Committees and the Directors was assessed through an internal evaluation process in 2025, as further detailed on page 122 of the Annual Report and Accounts. Following this evaluation, the Board recommends the re-election of all Directors. The biographical details of all Directors are set out below, on pages 104 and 105 of the Annual Report and Accounts, and on the Group's website at www.breedongroup.com/directors. In the Board's view, these illustrate why each Director's contribution is, and continues to be, important to the Company's long-term sustainable success.

RESOLUTION 6 to re-elect Amit Bhatia, Non-executive Chair

Amit has over 20 years' corporate finance and private equity experience. He is a founding Partner at Summix Capital, a strategic land and property fund. He was Executive Chairman of Hope Construction Materials until it was acquired by Breedon Group in August 2016, when he joined the Board as a non-executive director. Amit has a strong strategic and entrepreneurial approach which he brings to the Board together with his governance and stewardship experience which, as Chair, continues to ensure the long-term success of the Group.

Amit completed nine years' service as a director in August 2025. Provision 19 of the Code states that the Chair should not remain in post beyond nine years from their first appointment to the Board. To facilitate effective succession planning and the development of a diverse board, this period may be extended for a limited time, particularly where the Chair was an existing non-executive director on appointment.

Amit was appointed Chair in May 2019, three years after his appointment to the Board in August 2016. The Board considered it important to extend the Chair's term so as

Explanatory Notes

to provide stability and assurance at this time of growth. The Board believes it is in the best interests of all shareholders to extend Amit's term as director and Chair for at least three years, so as to provide the Board with continued successful leadership following the acquisitions of BMC and Lionmark, the growth of the third platform and the move to the FTSE 250.

The Board is of the view that Amit's continued role as Chair in no way compromises his independence of judgement and character and the overall composition of the Board remains a matter of continuous review. The Board believes that the Chair's extensive strategic knowledge and expertise together with his passion and commitment will provide stability at an important time in our growth. This view is supported by shareholders representing over half of our issued share capital, following formal engagement undertaken by our Senior Independent Director.

RESOLUTION 7 to re-elect James Brotherton, Chief Financial Officer. James joined Breedon in January 2021. Previously he was CFO of Tyman Plc between 2010 and 2019, prior to which he was Director of Corporate Development. Earlier in his career, James worked in investment banking roles at Citi and HSBC, after qualifying as a chartered accountant at Ernst & Young. James brings extensive international experience encompassing strategy, operational efficiency, systems development, capital generation and allocation, mergers and acquisitions and business integration. His expertise has played a key role in strengthening the Group's balance sheet and supporting its long-term strategic objectives.

RESOLUTION 8 to re-elect Carol Hui, OBE, Non-executive Director. Carol was the Non-executive Chairman at Robert Walters plc. She served as an Executive Board Director, the Chief of Staff and General Counsel at Heathrow Airport Limited where she successfully led their third runway expansion effort, winning endorsement from the Airports Commission in 2015. Carol has also held senior executive positions at large companies including Amey plc and British Gas plc and was a corporate finance lawyer with Slaughter and May. Carol is an experienced non-executive director and has received numerous legal and business awards throughout her career. Carol received an OBE in 2024 for her services to tourism. Carol provides a diverse perspective to the Board and provides it with valuable insight from her extensive strategic, commercial, legal and sustainability expertise.

RESOLUTION 9 to re-elect Pauline Lafferty, Non-executive Director. Pauline brings significant experience from an international career spanning manufacturing and supply, executive search and human resources. Since retiring from her role as Chief People Officer at Weir Group plc, where she was responsible for progressing the Group's agenda on all aspects of strategic HR, she has embarked on a non-executive portfolio that includes being the Chair of the Remuneration Committee for XP Power Limited, Scottish Events Campus Limited and Centurion Group. Prior to Weir Group plc, Pauline was a Partner with The Miles Partnership and an Executive Director at Russell Reynolds Associates in the UK and Australia, and Asia Pacific Director of Materials & Supply at Digital Equipment Corporation in Hong Kong. Pauline brings to the Board significant experience with regards to human resources, particularly in the key areas for the Board of talent, development and retention, employee engagement and cultural change. Pauline is a strong advocate on the Board for both employee engagement and positive culture changes.

RESOLUTION 10 to re-elect Helen Miles, Non-executive Director. Helen brings with her a breadth of operational and commercial experience having worked within regulated businesses together with her broader infrastructure experience developed across telecoms, leisure and banking. As a member of the UK Board of HomeServe, Helen was instrumental in delivering its future growth strategy and ensuring a sustainable, customer-focused business. As an experienced finance professional, Helen was previously Chief Financial Officer for Openreach, part of BT Group plc, and has extensive experience of delivering major business transformation across the group. Prior to BT Group, Helen worked in a variety of sectors and organisations such as Bass Taverns Limited, Barclays Bank plc, and Compass Group plc. Helen's strong expertise in the Board's key areas of growth strategy and sustainability, and her customer-focused business and transformation experience, fully supports and complements the Board's skill set. Helen contributes skills associated with her current appointment as an Executive Director on a FTSE 100 Board.

RESOLUTION 11 to re-elect Clive Watson, Non-executive Director. Clive has considerable finance experience, having previously been the Group Finance Director of Spectris plc, Chief Financial Officer and Executive Vice President for business support at Borealis, Group Finance Director at Thorn Lighting Group and held a variety of finance roles at Black & Decker. In 2019, Clive retired as a Non-executive Director of Spirax Sarco Engineering plc, where he was Chair of the Audit Committee and Senior Independent Director. Clive is both a chartered accountant and member of the Chartered Institute of Tax with significant finance experience in a variety of industries which allows him to continue to support the Board with its long-term success.

RESOLUTION 12 to re-elect Rob Wood, Chief Executive Officer. Rob has over 25 years' experience in the international building materials industry. He qualified as a chartered accountant with Ernst & Young and subsequently joined Hanson plc where he held senior positions including Finance Director Brick Continental Europe, Finance Director Building Products UK and Chief Financial Officer Australia and Asia Pacific.

Breedon Group plc Notice of Annual General Meeting and explanatory notes to shareholders

Explanatory Notes

a comprehensive understanding of the Group's operational challenges and strategic opportunities.

RESOLUTION 13: Authority to make political donations

Resolution 13 is to approve the limit of financial political contributions that the Company can make. It is not the Company's policy to make donations to, or incur expenditure on behalf of, political parties, other political organisations or independent election candidates and the Directors have no intention of using the authority for that purpose. However, it is possible that certain routine activities undertaken by the Company and its subsidiaries might unintentionally fall within the wide definition of matters constituting political donations and expenditure in the Act.

Shareholder approval is therefore being sought on a precautionary basis only, to ensure that neither the Company nor any company which, at any time during the period for which this resolution has effect, is a subsidiary of the Company commits a technical breach of the Act when carrying out activities in furtherance of its legitimate business interests.

The Directors are therefore seeking authority to make political donations to political parties, other political organisations, and independent election candidates not exceeding £100,000 in total. In line with guidance published by the Investment Association, this resolution is put to shareholders annually rather than every four years as required by the Act. This authority will expire at the conclusion of the Company's next annual general meeting or at 6.00pm on 28 July 2027, whichever is sooner.

RESOLUTION 14: Directors' authority to allot shares

Resolution 14 is proposed to renew the Directors' power to allot shares. Resolution 14(a) seeks to grant the Directors authority to allot, pursuant to section 551 of the Act, shares and grant rights to subscribe for or to convert any security into shares in the Company up to a maximum nominal

amount of £1,155,587.95. This represents 115,558,795 ordinary shares of 1.0 pence each, which is approximately one third of the Company's issued ordinary share capital as at 10 March 2026 (being the latest practicable date prior to the publication of this Notice).

In accordance with The Investment Association's Share Capital Management Guidelines (the 'Guidelines'), Resolution 14(b) seeks to grant the Directors authority to allot ordinary shares in connection with a fully pre-emptive offer in favour of ordinary shareholders up to an aggregate nominal value of £1,155,587.95. This represents 115,558,795 ordinary shares of 1.0 pence each, which is approximately one third of the Company's issued ordinary share capital as at 10 March 2026, (being the latest practicable date prior to the publication of this Notice).

The authorities sought under paragraphs (a) and (b) of this resolution will expire at the conclusion of the Company's next annual general meeting or at 6.00pm on 28 July 2027, whichever is sooner. The Directors have no present intention of exercising either of the authorities under this resolution, but the Board wishes to ensure that the Company has maximum flexibility in managing the financial resources of the Company.

As at close of business on 10 March 2026, the Company did not hold any treasury shares.

SPECIAL RESOLUTIONS

RESOLUTIONS 15 AND 16: Directors' authority to disapply pre-emption rights

Resolutions 15 and 16 are to approve the disapplication of pre-emption rights. The passing of these resolutions would allow the Directors to allot shares for cash under the authority given by Resolution 14 and/or sell treasury shares without first having to offer such shares to existing shareholders in proportion to their existing holdings.

The authority under Resolution 15 would be limited to:

(a) allotments or sales in connection with pre-emptive offers and offers to holders of other equity securities if required by the rights of those shares or as the Board considers necessary;

(b) allotments or sales (otherwise than pursuant to (a) above) up to an aggregate nominal amount of £346,676.38, which represents approximately 10% of the Company's issued ordinary share capital as at 10 March 2026 (being the latest practicable date prior to the publication of this Notice); and

(c) allotments or sales (otherwise than under paragraphs (a) and (b) above) up to an aggregate nominal amount of £69,335.27, which represents approximately 2% of the Company's issued ordinary share capital as at 10 March 2026 (being the latest practicable date prior to the publication of this Notice) to be used only for the purposes of making a follow-on offer to retail investors or existing investors not allocated shares in the offer.

Resolution 16 would give the Directors authority to (i) allot a further 10% of the issued ordinary share capital of the Company as at 10 March 2026 (being the latest practicable date prior to the publication of this Notice) for the purposes of financing a transaction which the Directors determine to be an acquisition or other capital investment contemplated by the Statement of Principles on Disapplying of Pre-emption Rights most recently published by the Pre-Emption Group prior to the date of this Notice (the 'Statement of Principles') and (ii) allot or sell shares (otherwise than under paragraph (i)) up to an aggregate nominal amount of £69,335.27, which represents approximately 2% of the Company's issued ordinary share capital as at 10 March 2026 (being the latest practicable date prior to the publication of this Notice) to be used only for the purposes of making a follow-on offer to retail investors or existing investors not allocated shares in the offer.

Explanatory Notes

The disapplication authorities under Resolutions 15 and 16 are in line with the guidance set out in the Statement of Principles. The Statement of Principles allows a board to allot shares for cash otherwise than in connection with a pre-emptive offer (i) up to 10% of a company's issued share capital for use on an unrestricted basis, (ii) up to a further 10% of a company's issued share capital for use in connection with an acquisition or specified capital investment announced either contemporaneously with the issue, or which has taken place in the preceding twelve-month period and is disclosed in the announcement of the issue and (iii) in the case of both (i) and (ii), up to an additional 2% in connection with a follow-on offer to retail investors or existing investors not allocated shares in the offer. The Directors confirm that, in considering the exercise of the authority under Resolutions 15 and 16, they intend to follow the shareholder protections set out in Part 2B of the Statement of Principles to the extent reasonably practicable.

The authorities contained in Resolutions 15 and 16 will expire at the conclusion of the Company's next annual general meeting or at 6.00pm on 28 July 2027, whichever is sooner.

RESOLUTION 17: Authority to make market purchases of own shares

This resolution seeks authority for the Company to make market purchases of its own ordinary shares as permitted by the Act. If passed, the authority limits the number of shares that could be purchased to a maximum of 34,667,638 ordinary shares (equivalent to approximately 10% of the Company's issued ordinary share capital as at 10 March 2026 (being the latest practicable date prior to the publication of this Notice)) and sets a minimum and maximum price. The authority will expire at the conclusion of the Company's next annual general meeting or at 6.00pm on 28 July 2027, whichever is sooner.

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

Any shares purchased in the market under this authority may be either cancelled or held as treasury shares, which may then be cancelled, sold for cash or used to satisfy obligations under its employee share schemes. No dividends are paid on shares while they are in treasury and no voting rights attach to treasury shares. The Directors believe that it is desirable for the Company to have this choice as holding the purchased shares as treasury shares would give the Company the ability to re-sell or transfer them in the future and so provide the Company with additional flexibility in the management of its capital base.

As at 10 March 2026 (being the latest practicable date prior to the publication of this Notice), the total number of outstanding awards to subscribe for ordinary shares in the Company amounted to 7,925,152 ordinary shares, representing approximately 2.3% of the Company's issued ordinary share capital. If the authority granted by this resolution were exercised in full, the outstanding awards would represent approximately 2.5% of the issued ordinary share capital as at 10 March 2026.

RESOLUTION 18: Notice period for general meetings, other than an annual general meeting

This resolution is to approve the calling of general meetings of the Company (other than an annual general meeting) on 14 clear days' notice. The notice period required by the Act for general meetings of the Company is 21 clear days unless (i) shareholders agree to a shorter notice period and (ii) the Company has met the requirements for electronic voting under the Companies (Shareholders' Rights) Regulations 2009. Annual general meetings must always be held on at least 21 clear days' notice.

The Directors confirm that the shorter notice period would not be used as a matter of routine, but only where flexibility is merited by the business of the meeting, the proposals are time-sensitive and it is thought to be to the advantage of shareholders as a whole. An electronic voting facility will be made available to all shareholders for any meeting held on such notice. The approval will be effective until the Company's next annual general meeting, when it is intended that a similar resolution will be proposed.

Breedon Group plc Notice of Annual General Meeting and explanatory notes to shareholders

Notes

NOTES TO NOTICE OF ANNUAL GENERAL MEETING

Entitlement to attend and voting

1. Pursuant to Regulation 41 of the Uncertificated Securities Regulations 2001 (as amended) and section 360B(2) of the Act, only those shareholders registered in the Company's Register of Members at 6.00pm on Monday 27 April 2026 (or not less than 48 hours before the time fixed for any adjourned meeting) shall be entitled to attend and vote at the AGM. Changes to the Register of Members after the relevant deadline shall be disregarded in determining the rights of any person to attend and vote at the AGM.

2. Persons who are not shareholders of the Company (or duly appointed proxies or corporate representatives) will not be admitted to the AGM unless prior arrangements are made with the Company.

3. If you wish to attend the AGM in person, registration for the AGM opens at 1.30pm on Wednesday 29 April 2026. You may find it useful to bring this Notice and the Annual Report and Accounts so that you can refer to them at the AGM. Please ensure that you bring ID.

4. It is proposed that all votes on the resolutions at the AGM will be taken by way of a poll rather than on a show of hands. The Company considers that a poll is more representative of shareholders' voting intentions because votes are counted according to the number of shares held and all votes tendered are taken into account. The results of the voting on all resolutions will be announced via the Regulatory News Service and published on our website www.breedongroup.com/investors as soon as practicable following the conclusion of the AGM.

Appointment of proxies

1. A member entitled to attend and vote at the Meeting convened by this Notice is also entitled to appoint one or more proxies to exercise all and any of their rights to attend and vote on their behalf at the Meeting. Where a member appoints more than one proxy in relation to the Meeting, each proxy must be appointed to exercise the rights attached to a different share or shares held by that member. A proxy need not be a member of the Company but must attend the Meeting in person.

2. If you are not a member of the Company but have been nominated by a member of the Company to enjoy information rights, you do not have a right to appoint any proxies under the procedures set out in this 'Appointment of proxies' section. Please read the section 'Nominated Persons' below.

3. Shareholders can:

(a) register their proxy appointment electronically (see note 12 below);

(b) appoint a proxy and give proxy instructions by requesting and returning a hard copy form of proxy (see notes 13 to 17 below);

(c) if they hold shares in CREST, register their proxy appointment by utilising the CREST electronic proxy appointment service (see notes 18 to 21 below); or

(d) if they are an institutional investor, register their proxy appointment via the Proxymity platform (see note 22 below).

1. To be valid, your proxy appointment and instructions must be received by MUFG Corporate Markets no later than 2.00pm on Monday 27 April 2026. The return of a completed form of proxy, other such instrument, any electronic voting instruction, any CREST Proxy Instruction (as described in note 19 below) or proxy appointment via the Proxymity platform (as described in note 22 below) will not prevent a shareholder attending the AGM and voting in person if they wish to do so.

2. Unless otherwise indicated on the Form of Proxy, CREST, Proxymity voting or any other electronic voting channel instruction, the proxy will vote as they think fit or, at their discretion, withhold from voting.

3. In the case of joint holders, the vote of the senior who tenders a vote, whether in person or by proxy will be accepted to the exclusion of the votes of any other joint holders and for this purpose seniority will be determined by the order in which the names are recorded in the Register of Members.

4. The Directors of the Company will interpret any ambiguous proxy appointments. The Chair of the Meeting will, in their capacity as proxy, interpret any voting instructions received. Their respective determinations shall be final.

It allows you to securely manage and monitor your shareholdings in real time, appoint a proxy online, keep your details up to date, access a range of information including payment history and much more. The app is available to download on both the Apple App Store and Google Play, or by scanning the relevant QR code below. Alternatively, you may access the Investor Centre via a web browser at: www.breedonshares.com

Appointment of proxies by hard copy proxy form

1. You may request a hard copy form of proxy directly from the MUFG Corporate Markets on 0371 664 0300 (or +44 371 664 0300 for overseas holders) or by emailing shareholderenquiries@cm.mpms.mufg.com. Calls are charged at the standard geographic rate and will vary by provider. Calls from outside the UK will be charged at the applicable international rate. Lines are open between 9.00am to 5.30pm (UK time), Monday to Friday excluding public holidays in England and Wales.

2. To be effective the completed and signed hard copy form of proxy must be received by post or (during normal business hours) by hand at the offices of MUFG Corporate Markets, PXS 1, Central Square, 29 Wellington Street, Leeds LS1 4DL (together with any power of attorney or other authority under which it is signed or a notarially certified copy of such power or authority) by no later than the deadline set out in note 8 above.

3. In the case of a shareholder which is a corporation, the form of proxy must be executed under its common seal or under the hand of some officer or attorney or other person duly authorised in that behalf.

4. To appoint more than one proxy using a hard copy form of proxy you may photocopy the requested form of proxy or contact the MUFG Corporate Markets to request additional forms of proxy (see note 13 above).

5. Please indicate the proxy holder's name and the number of shares in relation to which they are authorised to act as your proxy (which, in aggregate, should not exceed the number of shares held by you). Please also indicate if the proxy instruction is one of multiple instructions being given. If possible, all forms should be returned together in the same envelope.

Appointment of proxies through CREST

1. CREST members who wish to appoint a proxy or proxies through the CREST electronic proxy appointment service may do so by using the procedures set out in the CREST Manual. 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.

2. For a proxy appointment or instruction made using the CREST service to be valid, the appropriate CREST message (a 'CREST Proxy Instruction') must be properly (under CREST participant ID RA10) 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 (www.euroclear.com). 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, to be valid, be transmitted so as to be received by the Company's agent, MUFG Corporate Markets, by 2.00pm on Monday 27 April 2026. For this purpose, the time of receipt will be taken to be the time (as determined by the timestamp applied to the message by the CREST Application Host) from which the Company's agent is able to retrieve the message by enquiry to CREST in the manner prescribed by CREST. After this time any change of instructions to proxies appointed through CREST should be communicated to the appointee through other means.

3. 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 concerned to take (or, if the CREST member is a CREST personal member or sponsored member or has appointed a voting service provider(s), to procure that his or her CREST sponsor or voting service provider(s) take(s)) such action as shall be necessary to ensure that a message is transmitted by means of the CREST system by any particular time. In connection with this, CREST members and, where applicable, their CREST sponsors or voting service provider(s) are referred, in particular, to those sections of the CREST Manual concerning practical limitations of the CREST system and timings.

4. The Company may treat as invalid a CREST Proxy Instruction in the circumstances set out in Regulation 35(5) (a) of the Uncertificated Securities Regulations 2001 (as amended).

Notes

Proxymity

1. If you are an institutional investor, you may be able to appoint a proxy electronically via the Proxymity platform, a process which has been agreed by the Company and approved by the Company's Registrar. For further information regarding Proxymity, please go to www.proxymity.io. Your proxy must be lodged by 2.00pm on Monday 27 April 2026, or if the meeting is adjourned by the time which is 48 hours before the time of the adjourned meeting, to be considered valid. Before you can appoint a proxy via this process you will need to have agreed to Proxymity's associated terms and conditions. It is important that you read these carefully as you will be bound by them and they will govern the electronic appointment of your proxy. An electronic proxy appointment via the Proxymity platform may be revoked completely by sending an authenticated message via the platform instructing the removal of your proxy vote.

Changing proxy instructions

1. To change your proxy instructions, simply submit a new proxy appointment using the methods set out above.

2. Note that the cut-off time for receipt of proxy appointments (see note 8 above) also applies in relation to an amended instruction. Any amended proxy appointment received after the relevant cut-off time will be disregarded.

3. If you submit more than one valid proxy appointment in respect of the same shares, the appointment received last before the latest time for the receipt of proxies will take precedence.

Revoking your proxy appointment

1. To revoke a proxy instruction, you will need to inform the Company in writing by sending a signed hard copy notice clearly stating your intention to revoke your proxy appointment to MUFG Corporate Markets, PXS 1, Central Square, 29 Wellington Street, Leeds LS1 4DL or by registering the revocation of your proxy appointment at www.breedonshares.com or via the Investor Centre app.

2. In the case of a member that is a company, the revocation notice must be executed under its common seal or signed on its behalf by an officer of the company or a duly appointed attorney for the company. Any power of attorney or any other authority under which the revocation notice is signed (or a duly certified copy of such power or authority) must be included with the revocation notice.

3. The revocation notice must be received by MUFG Corporate Markets no later than 2.00pm on Monday 27 April 2026. If you attempt to revoke your proxy appointment but the revocation is received after the time specified, then your proxy appointment will remain valid unless you attend the AGM and vote in person.

Corporate representatives

1. Any corporation which is a member can appoint one or more corporate representatives who may exercise on its behalf all of its powers as a member provided that they do not do so in relation to the same shares.

Nominated Persons

1. Any person to whom this Notice is sent who is a person nominated under section 146 of the Act to enjoy information rights (a 'Nominated Person') may, under an agreement between him/her and the shareholder by whom he/she was nominated, have a right to be appointed (or to have someone else appointed) as a proxy for the AGM. Nominated Persons are advised to contact the shareholder who nominated them for further information on this and the procedure for appointing any such proxy.

2. If a Nominated Person has no such proxy appointment right or does not wish to exercise it, he/she may, under any such agreement, have a right to give instructions to the shareholder as to the exercise of voting rights. Such Nominated Persons are advised to contact the shareholders who nominated them for further information on this.

Right to ask questions

1. Under section 319A of the Act, any member attending the AGM has the right to ask questions at the AGM relating to the business of the AGM. The Company must cause to be answered any such question relating to the business being dealt with at the AGM but no such answer need be given if (a) to do so would interfere unduly with the preparation for the AGM or involve the disclosure of confidential information, (b) the answer has already been given on a website in the form of an answer to a question, or (c) it is undesirable in the interests of the Company or the good order of the AGM that the question be answered.

2. Please keep your questions and statements short and relevant to the business of the AGM to allow everyone who wishes to speak the chance to do so. It would be helpful if you could state your name before you ask your question. The Chair may nominate a representative to answer a specific question after the AGM or refer the question to the Company's website.
