Notice of Annual General Meeting 2026

LETTER FROM THE GROUP CHAIR

Dear Shareholder,

I am pleased to inform you that the Glanbia plc 2025 Annual Report and Financial Statements have been published and I have pleasure in inviting you to the 2026 AGM of the Company which will be held at the Killashee Hotel, Killashee, Naas, Co. Kildare, W91 DC98, Ireland at 11.00 a.m. (Irish time) on Wednesday, 29 April 2026. The AGM is an important event in our calendar and provides us with an opportunity to discuss the performance of the Glanbia plc group (the "Group") and other important matters with Shareholders and to listen and respond to your questions.

From a governance perspective the most significant changes during the year were:

I succeeded Donard Gaynor as Group Chair effective 1 January 2026 following his retirement on 31 December 2025. I was appointed Chair of the Nomination and Governance Committee on 31 December 2025;
Tirlán Co-Operative Society Limited ("Tirlán") and the Company agreed, with effect from 29 April 2026, to reduce the representation of Tirlán on the board of the Company from three to two and accordingly Thomas Phelan will retire as a director from the conclusion of the AGM;
William Carroll was appointed to the Board on 12 June 2025 as Non-Executive Director nominated by Tirlán ("Tirlán Nominee Director"), replacing Gerard O'Brien who retired on 11 June 2025;
Dan O'Connor retired from the Board on 30 April 2025. Senan Murphy was appointed as an Independent Non-Executive Director on 30 April 2025, also being appointed as Chair of Sustainability Committee and member of the Audit Committee in place of Ilona Haaijer. He was subsequently appointed Chair of the Audit Committee on 31 December 2025; and
In 2020, the Group set a target that at least 50% of the Independent (of Tirlán) Non-Executive Directors ("INED") would be female as new appointments are made. As of 3 January 2026, 41.6% of the Board members, and 62.5% of the INEDs, are female.

You will find the notice of the AGM (the "Notice") on pages 8 to 10 of this Circular, which sets out the business to be considered at the AGM, together with explanatory notes to the resolutions on pages 11 to 13 of this Circular.

The Board is proposing two new resolutions. Resolution 4 proposes the appointment of EY as statutory auditor of the Company following a tender process as described on pages 110 and 111 of the 2024 Annual Report and Financial Statements. Deloitte Ireland LLP were appointed in 2016 and steps down as auditor of the Company after 10 years. We thank Deloitte Ireland LLP for their diligence and look forward to working with EY. Resolution 13 proposes that Shareholders approve an authority to give the Company greater flexibility, should it be appropriate at the time and with Tirlán's agreement, to buy back a number of its own shares from Tirlán. If approved, the Company and Tirlán would enter into a directed buyback contract to enable this flexibility.

The Company has previously purchased shares from Tirlán in 2022 and 2025 as part of Tirlán share placings, and any shares acquired under this authority will be cancelled.

The proposed arrangement would allow the Company, at the discretion of the Directors, to purchase up to 4.99% of the Company's issued ordinary share capital, either through one or more standalone transactions or alongside an institutional placing by Tirlán. This authority does not require the Company or Tirlán to proceed with any transaction, but provides an additional option that may be used if considered in the best interests of shareholders. Further information in relation to (including the background to, and reasons for) the proposed arrangement is set out in Appendix I.

Recommendations

The Board considers that Resolutions 1 to 13 (described on pages 8 to 10) to be put to the AGM are in the best interests of the Company and Shareholders as a whole.

The Board unanimously recommends that you vote in favour of all resolutions as they intend to do in respect of their own beneficial holdings, which, as at 16 March 2026 (the "Disclosure Date") (being the latest practicable date prior to the publication of this Circular) amount to an aggregate 825,664 ordinary shares, representing approximately 0.34% of the issued ordinary shares in the capital of the Company as at the Disclosure Date.

Guidance notes for Shareholders wishing to attend the AGM are set out on pages 11 to 13.

Further action

Should you be unable to attend the AGM, you may appoint a proxy or proxies to exercise all or any of your rights to attend, speak and ask questions at the AGM. A Form of Proxy has been provided to each Shareholder. Appointment of a proxy will not preclude a Shareholder from attending, speaking, asking questions and voting at the AGM should the Shareholder subsequently wish to do so. To be valid, the Form of Proxy (if delivered by post) should be completed and returned to our Registrar, Computershare Investor Services (Ireland) Limited, P.O. Box 13030, Dublin 24, Ireland (the "Registrar"), in the pre-paid envelope provided.

Alternatively, you can lodge your proxy appointment electronically by visiting the website www.eproxyappointment.com provided by the Registrar. Further details on how to appoint a proxy and submit your voting instructions are set out in notes 6 and 7 on pages 14 and 15 of this Circular.

The process to be followed will depend on the manner in which a Shareholder holds their Ordinary Shares. In particular, persons who hold their interests in Shares as Belgian law rights through Euroclear Bank or as CDIs through CREST should consult with their stockbroker or other intermediary at the earliest opportunity for further information on the processes and timelines for submitting proxy votes for the AGM through the respective systems. Please note that all proxy appointments and instructions, whether postal or electronic must be received by 11.00 a.m. (Irish time) on Monday 27 April 2026, or by 1:59 p.m. EST on the Broadridge voting deadline (expected to be on Thursday 23 April 2026) in the case of voting instructions to be given to Broadridge by CDI holders, or by 10.00 a.m. (Irish time) on Monday 27 April 2026 in the case of voting instructions to be given to Euroclear Bank by EB Participants.

On behalf of the Board, I look forward to welcoming as many of you as possible to our AGM and I thank you for your continued support.

Yours sincerely

Paul Duffy
Group Chair

and if there shall be only a high (but not a low) or a low (but not a high) market guide price reported, or if there shall not be any market guide price reported, for any particular day, then that day shall not count as one of the said five business days for the purposes of determining the Appropriate Price. If the means of providing the foregoing information as to dealings and prices by reference to which the Appropriate Price shall be determined is altered or is replaced by some other means, then the Appropriate Price shall be determined on the basis of the equivalent information published by the relevant authority in relation to dealings on Euronext Dublin or its equivalent.

To consider and if thought fit, pass the following resolution as a special resolution:

"That the terms of the contract between the Company and Tirlán Co-Operative Society Limited ("Tirlán") (a copy of which has been produced to the meeting and has been made available for inspection at the Company's registered office from the date of the notice of this meeting to the date of this meeting) (the "Directed Buyback Contract") providing for off-market purchases (as defined by section 1072 of the Companies Act 2014) from Tirlán (or its nominee) of fully paid ordinary shares in the capital of the Company ("Ordinary Shares") at such times and at such prices and in such numbers as may be agreed by Tirlán and the Company in accordance with, and otherwise on the other terms and conditions set out in, the Directed Buyback Contract, be and are hereby approved and authorised for the purposes of section 1075 of the Companies Act 2014 and the Company be and is hereby authorised to make, subject to Tirlán's agreement, such off-market purchases from Tirlán, provided that:

(a) the authority hereby conferred shall, unless previously varied, revoked or renewed, expire at the conclusion of the next Annual General Meeting of the Company, or 29 July 2027 (whichever is earlier); and
(a) where the Company concludes a contract to purchase Ordinary Shares pursuant to the authority hereby conferred prior to the expiry of such authority (which will or may be executed wholly or partly after such expiry), it may make a purchase of Ordinary Shares pursuant to such contract as if the authority had not expired."

Glanbia plc
Notice of Annual General Meeting 2026

EXPLANATORY NOTES TO THE RESOLUTIONS

Resolution 1 – Review the Company’s affairs and receive and consider the Financial Statements for the year ended 3 January 2026 together with the reports of the Directors and Auditor thereon (ordinary resolution)

Shareholders are being asked to review the Company’s affairs and receive and consider the Financial Statements for the year ended 3 January 2026 together with the reports of the Directors and Statutory Auditor thereon.

The Financial Statements are available on the Company’s website and will be dispatched to Shareholders, if requested.

Resolution 2 – Declare a final dividend (ordinary resolution)

A final dividend for the year ended 3 January 2026 of 25.67€ cent per ordinary share is recommended by the Directors and is being put to Shareholders for their approval. If approved, the dividend will be paid on 30 April 2026 to holders of ordinary shares in the capital of the Company on the register of Shareholders of the Company at the close of business on 20 March 2026, making a total dividend in respect of the year ended 3 January 2026 of 42.87€ cent per ordinary share. In accordance with the constitution of the Company, the Shareholders cannot resolve to pay an amount greater than that recommended by the Directors.

Resolution 3 – Election or Re-election of Directors (ordinary resolution)

In accordance with the Irish Corporate Governance Code (the “Code”), all Directors, except for Thomas Phelan who will retire from his position as Non-Executive Director immediately following the AGM, are seeking election or re-election (as appropriate) at the AGM. The Group Chair has confirmed that each of the Directors who are seeking election or re-election, continue to be effective members of the Board and demonstrate their commitment to their responsibilities.

The Directors bring extensive senior leadership experience, strategic commercial business acumen, wide ranging operational experience and strong understanding of global capital markets and major transactions. Tirlán Nominee Directors are full-time farmers who have extensive knowledge of the global food and beverage industry and significant experience in the governance and strategic management of a global business gained from their tenure on the Boards of Tirlán and the Company. The Board believes that the considerable and wide-ranging experience and perspective of the Directors (the individual skills, experience and competence, and biographical details of whom are set out on pages 72 to 75 of the Annual Report) will continue to be invaluable to the Company and its long-term sustainable success and recommends their re-election.

Additionally, the Board and the Nomination and Governance Committee believe that all Non-Executive Directors demonstrate the essential characteristics of independence and bring independent challenge and deliberations to the Board; however, the two Non-Executive Directors nominated by Tirlán are not considered to be independent for the purposes of the Code.

Resolution 4 – Appointment of Statutory Auditor (ordinary resolution)

Shareholders will be invited to consider the appointment of EY as Statutory Auditor of the Company. Resolution 4 deals with the appointment of EY as Statutory Auditor of the Company. In its capacity as Statutory Auditor EY will also carry out the assurance of the Group’s sustainability statement under Part 28 of the Companies Act, which implements the EU Corporate Sustainability Reporting Directive. During 2024, the Audit Committee engaged in a formal tender process for the external audit of the Group’s financial statements. Following the conclusion of this process, the Board approved the appointment of EY as Statutory Auditor of the Company for the financial year commencing on 4 January 2026. This appointment is being put to shareholders for consideration as an advisory non-binding resolution. Full details of the tender process are set out on pages 110 and 111 of the 2024 Annual Report and Financial Statements.

Resolution 5 – Authorisation to fix the remuneration of the Statutory Auditor (ordinary resolution)

Shareholders are being asked to pass a resolution to authorise the Directors to fix the remuneration of the Statutory Auditor for the current financial year.

The Board has agreed to appoint EY Chartered Accountants as Statutory Auditor for the 2026 financial year end in place of Deloitte who have indicated their willingness to resign no later than the 2026 AGM.

This resolution is an advisory non-binding resolution which means that payments made or promised to Directors will not have to be repaid, reduced or withheld in the event that this resolution is not passed.

Resolution 7 - Approval to call an Extraordinary General Meeting on 14 days' notice (special resolution)

Shareholders are being asked to pass a resolution to agree to maintain the existing authority in the constitution of the Company which permits the Company to convene an extraordinary general meeting on 14 days' notice in writing where the purpose of the meeting is to consider an ordinary resolution. This authority will only be used when merited by exceptional circumstances.

Resolution 8 - Authority to allot relevant securities (ordinary resolution)

Shareholders are being asked to renew the Directors' authority to allot relevant securities, within the meaning of Section 1021 of the Companies Act 2014 up to a maximum nominal value of €4,819,275.90, representing 33% of the issued ordinary share capital of the Company as at the Disclosure Date. This authority will expire on the earlier of the close of business on 29 July 2027 or the date of the AGM of the Company in 2027.

Resolution 9 - Routine dis-application of preemption rights (special resolution)

Consistent with the Statement of Principles issued by the Pre-Emption Group, as updated in November 2022, Shareholders are being asked to dis-apply the strict statutory pre-emption provisions relating to the issue of new equity securities for cash in the event of a rights issue or other pre-emptive issue and to dis-apply the strict statutory pre-emption provisions in any other issue up to an aggregate nominal value of €1,460,386.62, being equal approximately to 10% of the nominal value of the Company's issued share capital as at the Disclosure Date. This 10% limit includes any treasury shares reissued by the Company while this authority remains operable.

Resolution 10 - Dis-application of pre-emption rights for an additional 10% for specific transactions (special resolution)

Resolution 10 is also being proposed as contemplated by the Statement of Principles issued by the Pre-Emption Group. If approved, the resolution will give the Directors an additional power to allot shares on a non-pre-emptive basis and for cash up to a further 10% of the issued share capital as at the Disclosure Date (being approximately an aggregate nominal value of €1,460,386.62, as at the Disclosure Date) in connection with an acquisition or a specified capital investment which is announced contemporaneously with the issue, or which has taken place in the preceding twelve-month period and is disclosed in the announcement of the issue. The 10% limit includes any treasury shares re-issued by the Company while this authority remains operable.

In respect of the authorities sought under resolutions 9 and 10, the Board acknowledges the provisions of the Pre-Emption Group's most recent Statement of Principles published in November 2022 and confirms that it will follow the general principles set out therein.

The authorities under each of resolution 9 and 10 will expire on the earlier of the close of business on 29 July 2027 or the date of the AGM of the Company in 2027.

Resolution 11 - Authorisation of market purchases of the Company's own shares (special resolution)

Shareholders are also being asked to pass a special resolution authorising the Company, or any of its subsidiaries, to purchase up to 10% of its own shares (being 24,339,777 shares, with an aggregate nominal value of €1,460,386.62 as at the Disclosure Date), less any ordinary shares that are purchased by the Company off-market from Tirlán pursuant to Resolution 13. Accordingly, the maximum number of ordinary shares that can be purchased by the Company or its subsidiaries under Resolutions 11 and 13 on an aggregate basis is 10% of the Company's own shares as at the Disclosure Date. This authority will expire at close of business on the earlier of 29 July 2027 or the date of the AGM of the Company in 2027. Such purchases would be made only at price levels, which are considered to be in the best interests of the Shareholders generally, after taking into account the Company's overall financial position.

Furthermore, the authority being sought from Shareholders will provide that the minimum price which may be paid for such shares shall not be less than the nominal value of the shares and the maximum price will be 105% of the then market price of such shares. This authority is being sought as it is common practice for public companies and the Board believes it is important that the Company should have the flexibility to return value to Shareholders in this manner.

EXPLANATORY NOTES TO THE RESOLUTIONS (CONTINUED)

Resolution 12 - Determination of the price range for the re-issue of treasury shares off-market (special resolution)

Shareholders are being asked to pass a special resolution authorising the maximum and minimum prices at which the Company may reissue, off-market, such shares as it may purchase and holds in treasury, and have not been cancelled.

Resolution 13 - Authority to make off-market purchases of ordinary shares from Tirlán

Resolution 13 will be proposed as a Special Resolution to grant the Company authority to make, subject to Tirlán's agreement, off-market purchases of ordinary shares from Tirlán pursuant to the Directed Buyback Contract which it is envisaged will be entered into by the Company shortly after the AGM. Tirlán is the Company's largest shareholder, holding approximately 17.89% of the issued share capital of the Company as at 16 March 2026. The Company has purchased its ordinary shares held by Tirlán in 2022 and 2025 as a participant in Tirlán's share placings and the purpose of seeking this authority is to provide additional flexibility for the Company for future share purchases from Tirlán. Any shares acquired from Tirlán under this authority will be cancelled. I would like to draw your attention to Appendix 1, which sets out the background to, and gives further information on, Resolution 13.

The Directors consider it may, in certain circumstances, be in the best interests of the Company and its Shareholders for the Company to purchase its own shares from Tirlán. If Resolution 13 is approved and Tirlán and the Company enter into the Directed Buyback Contract, the Company may agree with Tirlán to make off-market purchases of its ordinary shares at such times and on such number of occasions as the Directors may determine (provided it does not exceed 4.99% of the Company's Ordinary Share capital as at the date of the Directed Buyback Contract and at the date of the relevant purchase):

(a) by way of one or more standalone purchases; or
(b) in conjunction with any offer or sale by Tirlán by way of or including an institutional placing.

As mentioned above, the maximum number of ordinary shares that can be purchased by the Company under Resolutions 11 and 13 on an aggregate basis is 10% of its own shares as at the Disclosure Date and any shares purchased pursuant to the Directed Buyback Contract will reduce the maximum number of shares that can be purchased under the authority in Resolution 11 accordingly.

Any such off-market purchases shall be made at the

relevant market price on the date the Ordinary Shares are contracted to be purchased or, if made in conjunction with an institutional placing by Tirlán, at the placing or offering price as determined through a bookbuilding process, and otherwise on the terms and conditions of the agreed form Directed Buyback Contract, which is appended in Appendix 2.

The Directors will only make off-market purchases with Tirlán's agreement and where, in light of market conditions prevailing generally at the time, they consider that such off-market purchases will be in the best interests of Shareholders as a whole. Neither the Company nor Tirlán would be under an obligation to agree to make such off-market purchases or sales.

Under the Companies Act 2014, Resolution 13 will not be effective if Tirlán votes in respect of the Ordinary Shares to which Resolution 13 relates (being 4.99% of the Company's Ordinary Share capital) and the vote would not have been passed if Tirlán had not so voted. To avoid this possibility, Tirlán has therefore confirmed to the Company that it will abstain from voting in respect of the Ordinary Shares to which Resolution 13 relates.

Notice of Annual General Meeting 2026

APPENDIX 1 SUMMARY INFORMATION ON THE DIRECTED

BUYBACK CONTRACT

It is intended that, if Resolution 13 is approved, the Company and Tirlán will enter into the Directed Buyback Contract which will give the Company additional flexibility if appropriate at the relevant time and with the agreement of Tirlán, to acquire certain of its ordinary shares held by Tirlán. The Company has previously acquired its ordinary shares held by Tirlán in 2022 and 2025 as a participant in Tirlán's share placings. Any ordinary shares purchased under this authority will be cancelled. Under the proposed terms of the Directed Buyback Contract to be entered into between the Company and Tirlán, if Resolution 13 is approved, the Company may agree with Tirlán to make off-market purchases of its ordinary shares at such times and on such number of occasions as the Directors may determine (provided it does not exceed 4.99% of the Company's Ordinary Share capital as at the date of the Directed Buyback Contract or the date of the relevant purchase):

(a) by way of one or more standalone purchases; or
(b) in conjunction with any offer or sale by Tirlán by way of or including an institutional placing.

Neither the Company nor Tirlán would be under an obligation to agree to make such off-market purchases or sales. Under the proposed terms of the Directed Buyback Contract, an off-market purchase from Tirlán would only be made, provided that:

(a) the price payable by the Company to Tirlán (or his nominee) will:

(i) subject to paragraph (x) below, be the relevant market price per ordinary share on the date the ordinary share is contracted to be purchased as determined in accordance with the Directed Buyback Contract; and
(ii) be greater than or equal to the nominal value of an ordinary share at the relevant time (being €0.06 at the date of this Notice of General Meeting); and
(iii) be less than or equal to the higher of:

(A) 105% of the average of the closing prices for an ordinary share as derived from the Daily Official List of Euronext Dublin for the five business days immediately preceding the day on which the Ordinary Share is contracted to be purchased; and
(B) that stipulated by Article 3 (2) of Commission Delegated Regulation (EU) 2016/1052 and any corresponding provision of any replacement legislation;

(b) the proposed off-market purchase, when aggregated with any other transaction that comprises a "related party transaction" (to which subsections (1) to (3) of section 11100 of the Companies Act 2014 applies) between the Company and Tirlán (or its nominee) (excluding transactions entered into in the ordinary course of business on normal market terms and such other transactions excluded from aggregation by Irish company law) within the previous 12 months, or within the same financial year of the Company, shall not, at the date of such proposed off-market purchase, cause any percentage ratio, calculated in accordance with one or more class tests set out in Schedule 21 to the Companies Act 2014, to exceed 4.99%;

(c) the aggregate number of ordinary shares which the Company may purchase from Tirlán under the Directed Buyback Contract shall, without prejudice to paragraph (y) below, not exceed such number of ordinary shares that equals 4.99% of the Company's ordinary share capital in issuance (i) at the time of the relevant off-market purchase or (ii) on the date of the Directed Buyback Contract;

(d) the proposed off-market purchase, when aggregated with any other purchases made by the Company or any of its subsidiaries (a) under the Directed Buyback Contract, and (b) 'on-market' by the Company, pursuant to the authority set out in Resolution 11, shall not exceed 10% of the issued ordinary share capital of the Company as at the Disclosure Date; and

(e) the proposed off-market purchase will not result in the proportionate shareholding of Tirlán (together with any person with whom it is acting in concert) exceeding 29.99% of the Company's issued share capital as at the date of the relevant off-market purchase.

In addition, an off-market purchase from Tirlán in conjunction with an offer or sale by Tirlán (or its nominee) of ordinary shares by way of or including an institutional placement would only be made provided that:

(x) the price payable by the Company to Tirlán (or his nominee) will be the same price per ordinary share payable by institutional investors in the share offering as determined through a book building process; and
(y) the number of ordinary shares which the Company may purchase from Tirlán (or his nominee) in such an off-market purchase shall not exceed 50% of the number of ordinary shares, which are the subject of the relevant share offering by Tirlán; and

Glanbia plc
Notice of Annual General Meeting 2026

APPENDIX 1 (CONTINUED)

SUMMARY INFORMATION ON THE DIRECTED BUYBACK CONTRACT

(z) any off-market purchase from Tirlán (or his nominee) pursuant to the Directed Buyback Contract will settle immediately following and on the same business day as the settlement of the relevant share offering.

The Directed Buyback Contract shall only be entered into by the Company and Tirlán if Resolution 13 is passed. Once signed, it shall remain in force until the earlier of (a) expiry of the authority conferred by Resolution 13 (unless such authority is renewed); and (b) termination by agreement in writing between the Company and Tirlán.

Effect on Tirlán's shareholding of the exercise in full of the off-market purchase authority.

The shareholding of Tirlán as at 16 March 2026 (being the latest practicable date prior to the publication of this document) was 43,549,029 ordinary shares in the Company. If the Company (with the agreement of Tirlán) was to exercise in full the authority granted by Resolution 13, the shareholding of Tirlán would be 31,403,481 ordinary shares (excluding any ordinary shares which may otherwise be sold by Tirlán in an institutional placement in conjunction with an off-market purchase by the Company or otherwise). The exercise of the authority granted by Resolution 13 therefore would, subject to Tirlán's agreement in respect of any off-market purchase, have the effect of reducing Tirlán's holding of ordinary shares in the Company.

(c) on giving notice pursuant to Clause 3.2(b), the Company shall be bound to purchase and, if it agrees to sell, Tirlán shall be bound to sell (or procure the sale of) the number of Shares specified in the relevant notice at the relevant Share Offering Price at the relevant Off-Market Purchase Completion.

3.3 Subject to applicable law, each Party shall consult with the other Party and provide the other Party with a reasonable opportunity and sufficient time to comment on any references to any proposed off-market purchase in any announcement relating to such an off-market purchase or, if applicable, a Share Offering that the Company is participating in and the Party making the announcement will consider any comments received in good faith and shall make such amendments to the proposed announcement as are reasonably requested by the other Party (unless such amendments would be contrary to applicable law or would render the announcement inaccurate or misleading).
