Dear Shareholder

The following document gives notice that the Annual General Meeting ('AGM') of Diageo plc (the 'Company') will be held at Convene 133 Houndsditch, London, EC3A 7DB on Thursday, 6 November 2025 at 2.30 pm. As noted below, the AGM will be held as a hybrid meeting with the ability of shareholders to participate and attend the AGM electronically or in person.

As always, your vote is important to us and we encourage you to vote by completing and submitting a proxy form or by voting electronically in accordance with the instructions on pages 13 to 17.

Arrangements for the AGM

As was the case last year, we will be holding this year's AGM as a hybrid, combined physical and electronic meeting, enabling shareholders to attend the AGM in person or electronically. Those attending electronically will be able to participate in the AGM, submit questions and vote on resolutions without being physically at the meeting via a live webcast using the Lumi platform.

We encourage shareholders who cannot or do not wish to attend the meeting in person to participate in the AGM through the online Lumi platform, which can be accessed by following the instructions on pages 27 to 29. Shareholders attending the meeting electronically will be able to view me, the Interim Chief Executive Officer, other Directors and the Company Secretary conduct the business of the meeting and can submit questions and vote during the meeting as if they were attending in person. We are also providing a telephone line as detailed on page 29 to enable shareholders to ask questions of the Board relating to the business of the meeting orally during the AGM. Shareholders will also be able to submit such questions in advance of the AGM by sending them via email to agm.2025@diageo.com.

If you wish to attend the AGM in person, you are requested to register your intention to attend by emailing agm.2025@diageo.com by Tuesday, 4 November 2025.

Voting at the AGM

Voting at the AGM will be by way of poll rather than on a show of hands. This is a more transparent method of voting as shareholder votes are counted according to the number of shares held and will help to ensure an exact and definitive result. The poll will be conducted using electronic devices at the physical meeting and shareholders and proxies attending the meeting electronically will be able to vote live on all resolutions using the Lumi platform.

If you will not be participating in the meeting in person or electronically or otherwise wish to vote in advance, you may appoint a proxy as further detailed on pages 14 and 16. Those submitting a proxy are encouraged to consider appointing the Chair of the meeting, rather than some other named person, as their proxy. This will ensure that your vote is counted.

Recommendation

The Board considers that the resolutions contained in this Notice are in the best interests of your Company and the shareholders as a whole and recommends that you vote in favour of them. The Directors intend to vote in favour of these resolutions in respect of their own beneficial holdings.

Yours sincerely

Resolutions 5 to 12 (Directors seeking re-appointment)

In accordance with the UK Corporate Governance Code 2024 and the Company's articles of association, all currently serving Directors will retire and offer themselves for appointment or re-appointment by shareholders.

The Chair has confirmed that the Board has determined that each of the Non-Executive Directors is independent, continues to perform effectively and demonstrates commitment to their role, and that they are all influential individuals in their respective fields, backgrounds and countries. The Senior Independent Non-Executive Director and the other Non-Executive Directors are satisfied that the Chair is performing effectively and demonstrates commitment to his role, including commitment of time to Board and Committee meetings and his other duties.The Chair was considered to be independent on appointment as required by the UK Corporate Governance Code. The Board's balance of knowledge and skills, combined with their diversity and business experience, makes a major contribution to the proper functioning of the Board and its committees.

Biographical details of the Directors seeking re-appointment can be found on pages 78 and 79 of the Annual Report for the year ended 30 June 2025 and in Appendix B to this notice. These include details of the strengths of each Director, which demonstrate that each Director's contribution is, and continues to be, important to the Company's long-term sustainable success.

Copies of the Directors' service contracts (or, where appropriate, letters of appointment) are available for inspection during normal business hours at the Company's registered office on any business day, and will be available at the place where the AGM is being held from at least 15 minutes prior to, and during, the AGM.

Resolution 13 (re-appointment of auditor)

At each general meeting at which the accounts are laid before the members, the Company is required to appoint an auditor to serve until the next such meeting. The Audit Committee has assessed the effectiveness of PricewaterhouseCoopers LLP and recommends re-appointment. PricewaterhouseCoopers LLP has agreed to continue as the Company's auditor in respect of the financial year ending 30 June 2026.

Resolution 14 (remuneration of auditor)

This resolution authorises the Board, acting through the Audit Committee, to determine the remuneration of the Company's auditor.

Resolution 15 (political donations and political expenditure)

Under section 366 of the Act, the Company is required to seek shareholders' authority for any political donations and/or political expenditure made by the Company in the UK. At the AGM held on 26 September 2024, the Board was granted authority to make such political donations and/or incur such political expenditure, capped at £100,000.

Within the UK, it has been the Company's long-standing practice not to make payments to political parties and the intention is that this will remain the case. However, the legislation is very broadly drafted and may catch activities such as funding seminars and other functions to which politicians are invited, supporting certain bodies involved in policy review and law reform, and matching employees' donations to certain charities.

The group has not given any money for political purposes in the UK during the year. Our US based subsidiary, Diageo North America, Inc., made contributions solely at its own discretion to non-UK political candidates and committees in the United States, where it is common practice to do so. Contributions of approximately \$1.36 million (2024: \$1.1 million) were made by Diageo North America, Inc. during the financial year to US state and local candidates and committees, consistent with applicable laws. Additionally, our Australian based subsidiary made contributions, solely at its own discretion, totalling approximately \$0.01 million (2024: \$0.01 million).

The US contributions reflect no endorsement of a particular political party, and contributions were made with the aim of promoting a better understanding of our business and our views on commercial matters, as well as a generally improved business environment.

To avoid inadvertent infringement of applicable regulations in the UK, the Board has decided to continue to seek shareholders' authority for political donations and political expenditure in the UK in case any of the Company's normal activities are caught by the legislation. The authority sought would again be capped at £100,000. This authority will expire at the conclusion of next year's AGM (or, if earlier, 15 months from the passing of this resolution).

The Board will continue to seek to renew this authority at each AGM, in accordance with current best practice.

Resolution 16 (authority to allot shares)

At the AGM held on 26 September 2024, shareholders gave authority to the Board, which will expire at the conclusion of this year's AGM, to allot a maximum of £214,425,736 in nominal value of ordinary shares and any securities convertible into ordinary shares. Resolution 16 replaces the authority granted in 2024 and would allow the Board to allot ordinary shares, or to grant rights to subscribe for or convert any securities into ordinary shares up to an aggregate nominal amount equal to £214,666,136 (representing approximately 741,886,166 ordinary shares).

This amount represents approximately one-third of the Company's issued share capital (excluding treasury shares) as at 3 September 2025, being the latest practicable date prior to publication of this Notice (the 'Latest Practicable Date').

The authority sought under this resolution will expire at the conclusion of next year's AGM (or, if earlier, 15 months from the passing of this resolution). The Board will continue to seek to renew this authority at each AGM, in accordance with current best practice.

The Board has no present intention to exercise the authority sought under Resolution 16, except to satisfy options under the Company's share option plans (where relevant).

As at the Latest Practicable Date, 206,766,620 ordinary shares are held by the Company in treasury (representing approximately 9.29% of the total issued share capital (excluding treasury shares) of the Company).

Resolution 17 (adoption of the Diageo 2025 Share Value Plan)

The Diageo plc 2017 Share Value Plan (the 'Existing Plan') will expire on 20 September 2027. In anticipation of the expiry of the Existing Plan, the Board is proposing the adoption of the Diageo 2025 Share Value Plan (the 'Plan'), which is substantially the same as the Existing Plan. A summary of the Plan is set out in Appendix A on page 21 of this Notice.

Resolution 18 (disapplication of pre-emption rights)

This resolution would give the Board the power to allot ordinary shares (or sell any ordinary shares which the Company holds in treasury) for cash without first having to offer them to existing shareholders in proportion to their existing shareholdings.

This authority would be limited to allotments of new ordinary shares or sales of treasury shares, for cash, under Resolution 16 in connection with pre-emptive offers, or to allotments of equity securities in connection with the Company's employee share plans and the Company's employee share plans for joint ventures in which the group participates, or otherwise to allotments or sales of up to an aggregate nominal amount of £32,199,920 (representing approximately 111,282,923 ordinary shares), which is equivalent to just less than 5% of the issued ordinary share capital (excluding treasury shares) of the Company as at the Latest Practicable Date.

If the powers sought by Resolution 18 are used in relation to a non-pre-emptive offer, the Directors confirm their intention to follow the shareholder protections in paragraph 1 of Part 2B of the Pre-emption Group's Statement of Principles published in November 2022. The Board will continue to renew this authority at each AGM, in accordance with best practice.

This authority will expire at the conclusion of next year's AGM (or, if earlier, 15 months from the passing of this resolution).

Resolution 19 (authority to purchase own ordinary shares)

At the AGM held on 26 September 2024, the shareholders granted authority for the Company to buy up to a maximum of 222,316,603 of its own ordinary shares in the market.

This resolution renews and replaces that authority and would allow the Company to buy back up to 222,565,850 ordinary shares (i.e. approximately £64,399,840 in nominal value) in the market, representing just less than 10% of the issued ordinary share capital (excluding treasury shares), of the Company at the Latest Practicable Date.

At the Latest Practicable Date, the Company had no outstanding options to subscribe for ordinary shares.

The resolution sets out the lowest and highest prices that the Company can pay for the ordinary shares, the lowest price being the nominal value of an ordinary share and the highest price being the higher of:

• a. 5% above the average market value of the Company's ordinary shares for the five business days preceding the day of purchase; and
• b. the higher of the price of the last independent trade and the highest current independent purchase bid on the trading venues where the purchase is carried out.

This authority will expire at the conclusion of next year's AGM (or, if earlier, 15 months from the passing of this resolution). Any buyback would be by market purchases through the London Stock Exchange and/or other relevant markets or exchanges. Any ordinary shares so purchased would be either held as treasury shares or cancelled. In the period from 26 September 2024 to the Latest Practicable Date, no ordinary shares have been purchased and cancelled under the existing authority.

The Board would only authorise such purchases after careful consideration, taking account of other investment opportunities, appropriate gearing levels, the overall financial position of the group and whether the effect would be an increase in earnings per share and in the best interests of shareholders generally.

Resolution 20 (adoption of new articles of association)

The purpose of Resolution 20 is to adopt amended articles of association of the Company (the 'New Articles') to replace the existing articles of association which were adopted on 28 September 2023 (the 'Current Articles'). On 6 January 2025 the Company announced the launch of an asset reunification programme in partnership with AssetTrace+ with the aim of reuniting shareholders who have become disconnected from their Diageo shareholding and have unclaimed dividends as a result. Following the launch of the asset reunification programme, it is proposed that the New Articles are adopted to amend the provisions relating to untraced shareholders (being shareholders who, during a twelve-year period, have at least three unclaimed cash dividends and who have not otherwise been in communication with the Company).

Under the Current Articles, the Company has the right to sell the shares of an untraced shareholder if, following the relevant twelve-year period referred to above, a notice has been sent to their last known address, and a further three-month period has elapsed during which the untraced shareholder has not been in communication with the Company. This right will remain the same under the New Articles. However, under the Current Articles, following any such sale, the Company is required to hold the net proceeds as debtor to the untraced shareholder for a further six-year period. It is proposed that this is amended under the New Articles, such that the net proceeds, as well as any uncashed or unclaimed dividends or other sums in respect of the relevant shares, would immediately belong to the Company to use as the Board thinks fit.

The proposed amendments are to align with current market practice, and are designed to provide the Company with greater flexibility and reduce the administrative burden in dealing with the shares and unclaimed dividends and other sums of untraced shareholders.

If this resolution is passed, the New Articles will be adopted as the articles of association of the Company with effect from the passing of this resolution.

Resolution 21 (reduced notice of a general meeting other than an AGM)

In accordance with the Act, the notice period for general meetings (other than AGMs) is 21 clear days unless a shorter notice period is approved by shareholders via special resolution. The Company would like to have the ability to call general meetings (other than an AGM) on less than 21 clear days' notice. As in previous years, Resolution 21 seeks such approval.

The Company confirms that the shorter notice would not be used as a matter of routine but only in exceptional circumstances where the flexibility is merited by the nature of the business of the meeting and is thought to be in the interests of shareholders as a whole. In accordance with the Act, the Company would offer the facility for members to vote by electronic means at any such meeting.

You must use the electronic address specified for this purpose on the Company's website (please see '2025 Annual General Meeting' at www.diageo.com) and your appointment must reach the Registrar by 2.30 pm on Tuesday, 4 November 2025 (or not less than 48 hours before the time fixed for any adjourned AGM, provided that no account shall be taken of any part of a day that is not a working day). Please note that any electronic communication that is found to contain a computer virus will not be accepted. Alternatively, shareholders can vote electronically via the Investor Centre app, which is a free app for smartphone and tablet provided by MUFG Corporate Markets (the company's registrar). It allows you to securely manage and monitor your shareholdings in real time, take part in online voting, 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.

• 1. If two or more valid but differing appointments of a proxy are received in respect of the same share for use at the same AGM, the appointment of proxy which is last received (regardless of its date or the date of its signature) shall be treated as replacing and revoking the others as regards that share; if the Company is unable to determine which was last received, none of them shall be treated as valid in respect of that share. Participants in the Company's Employee Share Plans or holders of shares in the Computershare SPA should refer to notes 20 and 21.
• 1. Unless voting instructions are indicated on the Form of Proxy, a proxy may vote or withhold their vote as they think fit on the resolutions or on any other business (including amendments to resolutions) which may come before the AGM. A vote withheld is not a vote in law and will not be counted in the calculation of the proportion of votes for or against a resolution.
• 1. The return of the Form of Proxy or the appointment of a proxy via the electronic voting section of the Company's website (www.diageo.com) or via CREST or Proxymity will not in itself prevent you from attending and voting in person. In the case of joint holders, any one holder may vote. If more than one holder is present at the AGM or purports to vote by proxy, only the vote of the senior will be accepted, seniority being determined by the order in which names appear on the Register.
• 1. A shareholder must inform the Company in writing of any termination of the authority of a proxy.

Appointment of proxies through CREST

• 1. CREST members who wish to appoint and/or give instructions to a proxy or proxies through the CREST electronic proxy appointment service may do so in accordance with the procedures described in the CREST manual (available by logging in at www.euroclear.com). In order for a proxy appointment made through CREST to be valid, the appropriate CREST message (a 'CREST Proxy Instruction') must be properly authenticated in accordance with Euroclear UK & International Limited specifications and must contain the information required for such instructions, as described in the CREST manual. The message must be transmitted so as to be received by the issuer's agent (ID RA10) by the latest time(s) for receipt of proxy appointments as set out in note 9.
• 1. For this purpose, the time of receipt will be taken to be the time (as determined by the timestamp applied to the message by the CREST Application Host) from which the issuer's agent is able to retrieve the message by enquiry to CREST in the manner prescribed by CREST. After this time any change of instructions to proxies appointed through CREST should be communicated to the appointee through other means. 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.
• 1. 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.
• 1. 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, to procure that their CREST sponsor or voting service provider(s) take(s)) such action as shall be necessary to ensure that a message is transmitted by means of the CREST system by any particular time. In this connection, CREST members and, where applicable, their CREST sponsors or voting system provider are referred, in particular, to those sections of the CREST manual concerning practical limitations of the CREST system and timings.

Voting using Proxymity

1. If you are an institutional investor you may also be able to appoint a proxy electronically via the Proxymity platform, a process which has been agreed by the Company and approved by the Registrar. For further information regarding Proxymity, please go to www.proxymity.io. Your proxy must be lodged by 2.30 pm on Tuesday, 4 November 2025 in order to be considered valid, or, if the meeting is adjourned, by the time which is 48 hours before the time of the adjourned meeting (excluding non-working days). 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.

Participants in Diageo employee share plans or holders of shares in the Computershare SPA

• 1. Participants in the Company's Employee Share Plans and/or holders of shares in the Computershare SPA should complete the Form of Direction received via email from planadmin-noreply@equateplus.com.

• 1. If you have been nominated to receive general shareholder communications directly from the Company, it is important to remember that your main contact in terms of your investment remains the registered shareholder or custodian or broker who administers the investment on your behalf.

• 1. The Company may not require the shareholders requesting any such website publication to pay its expenses in complying with sections 527 or 528 of the Act. Where the Company is required to place a statement on a website under section 527 of the Act, it must forward the statement to the Company's auditor not later than the time when it makes the statement available on the website. The business which may be dealt with at the AGM includes any statement that the Company has been required, under section 527 of the Act, to publish on a website.
• 1. Any shareholder who has not otherwise received confirmation that their vote on the polls at the AGM has been validly recorded and counted and has no other reasonable means of confirming this, may, within 30 days from the date of the AGM, request information from the Company allowing them to confirm that their vote on the polls at the AGM has been validly recorded and counted, by using the contact details of the Registrar of the Company given in note 33 below.

APPENDIX A

Summary of the Diageo 2025 Share Value Plan

The following is a summary of the principal features of the Diageo 2025 Share Value Plan (the 'Plan'), which operates within the United States Internal Revenue Code 1986 ("Code"), as amended. The Plan replaces the Diageo plc 2017 Share Value Plan (the "Existing Plan") which will expire on 20 September 2027 but without substantive changes to the terms or operation of the Existing Plan.

Eligibility

Employees of Diageo North America, Inc. and other subsidiaries of Diageo in the USA as selected by the Board from time to time will be eligible to participate in the Plan, provided that they meet certain requirements.

Operation

The Plan provides a tax efficient method of saving for employees in the USA combined with an option to buy American Depositary Shares ('ADS') representing Ordinary Shares in the Company ('Options'). Each participant will be entitled to participate in the Plan on the same basis. Once participants have elected the total annual amount they wish to save, funds are collected on a monthly basis through payroll for one year, following the end of which Options will be exercised by the trustee of the Plan acquiring ADSs on behalf of the participants.

Acquisition of Shares

Subject to shareholder approval of the Plan, it is proposed that the first grant of Options will be made in 2026. No Options may be granted more than ten years after the Plan is approved by shareholders. Options under the Plan are personal to the participants, may not be transferred except on death and are not pensionable.

The fair market value of ADSs granted to any participant in any year under the Plan and any other employee stock purchase plans (within the meaning of the Code) may not exceed the limit permitted by the relevant tax legislation or whatever limit the Company sets (which will not exceed the limit set by the relevant tax legislation). The current limit under the Plan is \$25,000 per annum, determined at the time of grant.

Acquisition Price

The subscription price of ADSs purchased on exercise of Options under the Plan will be not less than the lower of 85% of the closing price for such ADSs as reported on the New York Stock Exchange on the (i) trading day immediately before the date of grant of the Options and (ii) last trading day of the calendar year following the year in which the Options were granted, or such longer period up to 27 months as determined by the Board.

Limits of the Plan

The Plan is subject to the following limits:

In any ten year period, the number of the Company's shares which may be issued under the Plan, and under any employees' share scheme established by the Company, may not exceed 10% of the ordinary share capital of the Company in issue (excluding treasury shares) from time to time.

In addition, the number of shares that can be issued under the Plan during its life will be 2,800,000 ordinary shares.

Leavers

If a participant leaves employment as a result of retirement, disability, redundancy or their employer no longer being part of the Company's group, they may elect within three months from the date they leave to bring their option to an end or to exercise their option on the normal exercise date.

If a participant leaves employment as a result of death, their personal representatives may elect within three months from the date of the participant's death to bring their option to an end or to exercise their option on the normal exercise date.

If a participant leaves employment for any other reason, their option will lapse and the savings held for them shall be returned (unless the Board determines otherwise).

Corporate events

In the event of a change of control of the Company, the participant can elect whether to continue to save or receive a settlement amount in cash.

Variation of capital

In the event of any variation in the shares of the Company, the Board may make such adjustments as it considers appropriate to the number of ADSs under option and the subscription price.

Amendments

The Board may at any time amend the Plan provided that any such changes do not cause the Plan to fail to comply with the requirements for employee stock purchase plans under the Code or any other requirement of applicable law or regulation.

The prior approval of the Company in general meeting must be obtained for any amendment (a) as required by the Code or (b) to the advantage of participants which is made to the provisions relating to eligibility, individual or overall limits, the basis for determining employee's entitlement to, and the terms of, ADSs provided under the Plan, and the adjustments that may be made in the event of any variation of share capital. Minor amendments to benefit the administration of the Plan, to take account of a change in legislation or to obtain favourable tax, exchange control or regulatory treatment for employees, the Company or any subsidiary of the Company, do not require the approval of the Company in general meeting.
