Dear Shareholder On behalf of the Board, I am pleased to invite you to AstraZeneca’s 2024 AGM which will be held on Thursday 11 April 2024 at 14:30 (BST). At the AGM, Pascal Soriot, our Chief Executive Officer, will update you on the progress of the business in 2023. The AGM will also include a question and answer session before we conduct the formal business of the meeting. Digitally-enabled AGM This year’s AGM will be a digitally-enabled meeting and broadcast live. The Board therefore looks forward to you joining us at the AGM via the online platform, which can be found at: https://web.lumiagm.com/157465049. Digitally-enabled AGMs are optimised for online participation. They are intended to be accessible and engaging, allowing the Company’s geographically diverse shareholder base to participate in the meeting and engage with the Board. With the majority of underlying share ownership being located outside the UK, the digitally-enabled AGM provides an opportunity for non-UK based shareholders, including holders of the Company’s American Depositary Shares and Nasdaq Stockholm listed shares, to participate in the meeting. The rights of shareholders to vote and to participate in the digitally-enabled AGM remain the same. As we are moving to a digitally-enabled AGM this year, I would like to emphasise that the content and presentation will be optimised for that format. Management and Board members will take part in the AGM electronically and will not be available to meet shareholders. Shareholders who still want to attend in person will be invited to connect online to the meeting and offered support in doing so. I encourage shareholders to join the AGM via the online platform, and to ask questions and vote, so that the Board can continue to strengthen its engagement with you. A step-by-step guide on how to join the meeting electronically via the online platform can be found on pages 13 to 15. Details of how to submit questions, and how to vote, either in advance or during the meeting, can be found in the General Notes from page 10. Board of Directors I am pleased to note that, since the last AGM, we welcomed Anna Manz as a new Non-Executive Director of the Board on 1 September 2023. Anna brings extensive cross-sector business skills and knowledge to the Board, having held international roles in North America and Asia Pacific and served as an executive and non-executive director in large, listed companies. Anna’s significant financial and strategic leadership experience, including in areas such as risk, treasury and accounting, will enable her to contribute fully to the work of our Audit Committee, which she has also joined with effect from 1 September 2023. For further details on Anna’s and the other Directors’ experience, skills and expertise, please see pages 16 and 17. At the AGM, as usual and in accordance with the Company’s Articles of Association, all Directors will stand for election or re-election, as applicable, as part of the ordinary business of the meeting. Full details are set out in the Resolutions in the Notice of AGM from page 4. Voting Shareholders will still be able to vote as they have in previous years and are encouraged to vote either in advance from the date of this Notice of AGM, or on the day, via the online platform. Details of all of the voting options available to shareholders are set out in the General Notes section of this Notice of AGM, from page 10. Registration of shareholder questions The Board values questions from shareholders and it is important to us that we have the opportunity to hear from you, our shareholders. Shareholders will be able to ask questions of the Board in advance of the AGM or during the meeting. Full details on how to ask questions, either in advance or during the meeting, are set out in the General Notes section of this Notice of AGM, from page 10. “I encourage shareholders to join the AGM via the online platform, and to ask questions and vote, so that the Board can continue to strengthen its engagement with you.” 2 Notice of Annual General Meeting 2024 and Shareholders’ Circular Letter from the Chair

Resolution 12 That subject to the passing of Resolution 10, as set out in the Notice of AGM of the Company convened for 11 April 2024, and in addition to any power given to them pursuant to Resolution 11 in the Notice of AGM, the Directors be generally empowered pursuant to section 570 and section 573 of the Companies Act 2006 to allot equity securities (as defined in the Companies Act 2006) for cash, pursuant to the authority conferred by Resolution 10 in the Notice of AGM as if section 561(1) of the Companies Act 2006 did not apply to the allotment. This power: (a) expires (unless previously renewed, varied or revoked by the Company in a general meeting) at the end of the next Annual General Meeting of the Company after the date on which this Resolution is passed (or, if earlier, at the close of business on 11 July 2025), but the Company may make an offer or agreement which would or might require equity securities to be allotted after expiry of this power and the Directors may allot equity securities in pursuance of that offer or agreement as if this power had not expired; (b) in the case of the authority granted under Resolution 10(a)(i)(A) shall be limited to: (i) the allotment of equity securities (otherwise than pursuant to paragraph (b)(ii) below) up to an aggregate nominal amount of US$38,755,029, provided that the allotment is for the purposes of financing (or refinancing, if the power is used within 12 months of the original transaction) a transaction which the Directors determine to be an acquisition or specified capital investment of a kind contemplated by the Statement of Principles on Disapplying Pre-Emption Rights most recently published by the Pre-Emption Group prior to the date of this Notice of AGM; and (ii) when any allotment of equity securities is or has been made pursuant to paragraph (b)(i) above (a paragraph 12(b)(i) allotment), the allotment of equity securities up to an aggregate nominal amount equal to 20% of the nominal amount of that paragraph 12(b)(i) allotment, provided that any allotment pursuant to this paragraph (b)(ii) is for the purposes of a follow-on offer determined by the Directors to be of a kind contemplated by paragraph 3 of Part 2B of the Statement of Principles on Disapplying Pre-Emption Rights most recently published by the Pre-Emption Group prior to the date of the Notice of AGM; and (c) applies in relation to a sale of shares which is an allotment of equity securities by virtue of section 560(3) of the Companies Act 2006 as if in the first paragraph of this resolution the words ‘pursuant to the authority conferred by Resolution 10 in the Notice of AGM’ were omitted.

Resolutions 6–7: Directors’ Remuneration Report and Directors’ Remuneration Policy The purpose of Resolution 6, which is proposed as an ordinary resolution, is to receive and approve the annual statement of the Chair of the Remuneration Committee (the Statement) and the Annual Report on Remuneration for the year ended 31 December 2023 (the 2023 Remuneration Report). The Statement and the 2023 Remuneration Report can be found on pages 102 to 126 of the Annual Report, which is available on our website, www.astrazeneca.com, or by request from the Company. The Board considers that appropriate executive remuneration plays a vital part in helping to achieve the Company’s overall objectives and, accordingly, and in compliance with the legislation, shareholders will be invited to approve the Statement and the 2023 Remuneration Report. The 2023 Remuneration Report gives details of the remuneration paid to the Directors during the year ended 31 December 2023. The vote on the Statement and the 2023 Remuneration Report is advisory in nature in that payments made or promised to Directors will not have to be repaid, reduced or withheld in the event that Resolution 6 is not passed. The purpose of Resolution 7, which is proposed as an ordinary resolution, is to invite shareholders to approve the Directors’ Remuneration Policy (the Policy). The vote on the Policy is a binding vote. If Resolution 7 is passed, the Policy shall take effect from the date of the AGM (the Effective Date), meaning that from the Effective Date the Company may not make a remuneration payment or a payment for loss of office to a person who is, is to be, or has been a Director of the Company unless the payment is consistent with the Policy, or has been otherwise approved by shareholder resolution. If the Policy is not approved for any reason, the Company will, if and to the extent permitted by the Companies Act 2006, continue to make payments to Directors in accordance with the existing Policy and will seek shareholder approval for a further revised Policy as soon as is practicable. If approved by shareholders, the Policy will be subject to a binding shareholder vote by ordinary resolution in a further three years, except in the event that a change to the Policy is proposed or the advisory vote on the Statement and the Annual Report on Remuneration is not passed in any year subsequent to the approval of the Policy. The substantive differences between the Policy approved by shareholders at the 2021 Annual General Meeting and the proposed Policy are: > Increasing the maximum opportunity under the annual bonus from 250% to 300% of base pay. > Any shares awarded under the Deferred Bonus Plan will now ordinarily be retained in the event of a resignation of an Executive Director and vest at the end of the relevant deferral period, with the Remuneration Committee retaining its discretion to lapse awards on resignation should it deem it necessary to do so. > Increasing the maximum opportunity under the Performance Share Plan from 650% to 850% of base pay. As set out in the Statement, the minimum shareholding requirement for Executive Directors will increase to align with their maximum variable pay opportunity, which will continue for two years post termination of employment. The Policy is set out on pages 127 to 138 of the Annual Report and the Remuneration Committee’s considerations when developing the Policy, including details of engagement with major shareholders, are described within the Statement from page 102. Both the Remuneration Committee and the Board are satisfied that our remuneration practices are aligned to the delivery of the Company’s strategy and promote long-term sustainable value creation for shareholders. Resolutions 1–2: Accounts and Dividend The purpose of these resolutions, which are proposed as ordinary resolutions, is: > To receive the Company’s Accounts, the Reports of the Directors and Auditor and the Strategic Report for the year ended 31 December 2023. > To confirm the first interim dividend of US$0.93 (71.8 pence, SEK 9.64) per ordinary share and to confirm, as the final dividend for 2023, the second interim dividend of US$1.97 (156.0 pence, SEK 20.65) per ordinary share. Resolutions 3–4: Re-appointment of Auditor and Authority to agree the remuneration of the Auditor The purpose of these resolutions, which are proposed as ordinary resolutions, is: > To re-appoint PricewaterhouseCoopers LLP as Auditor of the Company until the conclusion of the next general meeting of the Company at which accounts are laid. > To authorise the Directors to agree the remuneration of the Auditor. Resolution 5: Election and re-election of Directors At the AGM, as usual and in accordance with the Company’s Articles of Association, all of the Directors are retiring. The biographical details of each Director presenting themself for election or re-election by ordinary resolution are set out in the Notice of AGM and Shareholders’ Circular from page 16. Anna Manz joined the Board as a Non-Executive Director of the Company with effect from 1 September 2023 and will stand for election by shareholders for the first time at the AGM. The Board has considered the independence of the Non-Executive Directors who served during 2023 and all those standing for election or re-election at the AGM under the 2018 UK Corporate Governance Code (the Code). The Chair, Michel Demaré, met the independence criteria prescribed in the Code upon his appointment as Chair. In accordance with the Code, it is not considered appropriate to repeat the test following appointment as Chair. The Board concluded that, with the exception of Marcus Wallenberg, all the Non-Executive Directors presenting themselves for election or re-election are independent in character and judgement and there are no relationships or circumstances likely to affect their character or judgement. During the Board’s annual evaluation of its performance and that of its Committees and individual Directors in 2023, the Board concluded that each Director continues to make effective and valuable contributions to the Board and to demonstrate commitment to the role. More information about these matters and how the Board operates can be found in the Corporate Governance Report in the Annual Report, which is available on our website, www.astrazeneca.com, or by request from the Company. AstraZeneca PLC Registered No. 2723534 1 Francis Crick Avenue, Cambridge Biomedical Campus, Cambridge, CB2 0AA 7 Explanatory notes to the Resolutions

Resolution 8: Amendment to the AstraZeneca Performance Share Plan 2020 The purpose of Resolution 8, which is proposed as an ordinary resolution, is to approve an amendment to the AstraZeneca Performance Share Plan 2020 (PSP) which was originally approved by shareholders at the 2020 AGM, with further amendments approved by shareholders at the 2021 Annual General Meeting. A copy of the PSP that reflects the proposed amendment is available for inspection, as noted on page 12 of this Notice of AGM. The amendment ensures: > The maximum number of the Company’s shares which may be put under an award in respect of any employee will be increased from such number as has a total market value equal to 650% of that employee’s base pay to such number as has a total market value equal to 850% of that employee’s base pay or, in the case of an Executive Director, such limit as is set out in the shareholder approved Remuneration Policy from time to time, as further set out in the revised Remuneration Policy on pages 127 to 138 of the Annual Report and in the notes to Resolutions 6-7 in this Notice. The Remuneration Committee’s rationale for increasing the maximum opportunity for a PSP award is set out in detail in the Directors’ Remuneration Report from page 102 of the Annual Report. Resolution 9: Political donations The purpose of Resolution 9, which is proposed as an ordinary resolution, is to authorise the Company and/or its subsidiaries to make limited political donations or incur limited political expenditure, within the meaning of such expressions as contained in the Companies Act 2006 (the Act). It is the Company’s policy to not make such political donations or incur such political expenditure. The Company is not intending to alter this policy. However, the definitions of political donations and political expenditure under the Act are very broad. Some of the Company’s activities may therefore fall within the definitions of the Act. Without the necessary authorisation, the Company’s ability to communicate its views effectively to, for example, interest groups or lobbying organisations could be inhibited. Accordingly, the Company believes that the authority contained in Resolution 9 is necessary to allow it and its subsidiaries to fund activities which are in the interests of shareholders that the Company should support. Such authority will enable the Company and its subsidiaries to be sure that they do not unintentionally commit a technical breach of the relevant sections of the Act. Any donations or expenditure, which may be made or incurred under the authority of Resolution 9, will be disclosed in next year’s Annual Report. Resolution 10: Allotment of new shares The purpose of Resolution 10, which is proposed as an ordinary resolution, is to enable the Directors to exercise their power under the Company’s Articles of Association to allot new shares in the capital of the Company. The Directors may only allot shares or grant rights to subscribe for shares, or convert any security into shares, if authorised to do so by shareholders. The Directors’ authority will only be valid until the conclusion of the Annual General Meeting in 2025 or the close of business on 11 July 2025, whichever is earlier. Other than the allotment of shares for the purposes of fulfilling the Company’s obligations under certain of its share plans, the Directors have no present intention to exercise this authority. However, it is considered prudent to acquire the flexibility that this authority provides. The Directors intend to seek renewal of this authority annually. > Paragraph (a)(i)(A) of Resolution 10 would authorise the Directors to allot (or grant rights to subscribe for, or convert any security into) shares in the Company up to a maximum nominal amount of US$129,170,514. This amount represents 33.33% of the Company’s total issued ordinary share capital as at 13 February 2024 (being the last practicable date prior to publication of this Notice of AGM). > Paragraph (a)(i)(B) of Resolution 10 would authorise the Directors to allot shares and grant rights to subscribe for, or convert any security into, shares, up to an aggregate nominal amount of US$258,341,028 (less any shares allotted pursuant to paragraph (a)(i)(A) of Resolution 10) in connection with a pre-emptive offer to existing shareholders (with exclusions to deal with fractional entitlements to shares and overseas shareholders to whom the offer cannot be made due to legal and practical problems). This amount represents 66.66% of the Company’s total issued ordinary share capital as at 13 February 2024. This is in accordance with the latest guidelines published by the Investment Association. At 13 February 2024, no shares in the Company were held as treasury shares. For information, during 2023, the Directors used equivalent authorities granted at previous Annual General Meetings for the purposes of fulfilling the Company’s obligations under its various share plans. The number of shares allotted during 2023 and the percentage of the Company’s share capital they represented at 31 December 2023 are shown in the following table.

Resolutions 11–12: Pre-emption rights The purpose of Resolutions 11 and 12, which are proposed as special resolutions, is to grant authority to the Directors (subject to the passing of Resolution 10) to allot shares of the Company and to sell treasury shares for cash without first offering them to existing shareholders in proportion to their existing holdings. If the Directors wish to allot shares, or grant rights to subscribe for, or convert securities into, shares, or sell treasury shares, for cash (unless pursuant to an employees’ share scheme), they must first offer them to existing shareholders in proportion to their holdings. This provision is designed to prevent the holdings of existing shareholders being diluted against their wishes by the allotment of new shares. There may be occasions however when the Directors need the flexibility to finance business opportunities by the issue of shares without a pre-emptive offer to existing shareholders. This cannot be done under the Act unless shareholders have first given a limited waiver of their pre-emption rights. Resolutions 11 and 12 ask shareholders to grant this limited waiver. Resolution 11 contains a three-part waiver: > The first part (at paragraph (b)(i) of Resolution 11) is limited to the allotment of shares for cash on a pre-emptive basis to allow the Directors to make appropriate exclusions and other arrangements to resolve legal or practical problems which, for example, might arise in relation to overseas shareholders. > The second part (at paragraph (b)(ii) of Resolution 11) is limited to the allotment of shares for cash up to an aggregate nominal value of US$38,755,029 (which includes the sale on a non pre-emptive basis of any shares held in treasury), which represents approximately 10% of the Company’s total issued ordinary share capital as at 13 February 2024 (being the last practicable date prior to publication of this Notice of AGM). 8 Notice of Annual General Meeting 2024 and Shareholders’ Circular Explanatory notes to the Resolutions continued

> The third part (at paragraph (b)(iii) of Resolution 11) applies to the allotment of shares for cash for the purposes of a follow-on offer when an allotment of shares has been made under the second waiver contained at paragraph (b)(ii) of Resolution 11. It is limited to the allotment of shares having an aggregate nominal value of up to 20% of the nominal value of any shares allotted under the second waiver. The follow-on offer must be determined by the Directors to be of a kind contemplated by the Pre-Emption Group’s 2022 Statement of Principles. The Directors confirm that they will follow the shareholder protections in Part 2B and the expected features of a follow-on offer in paragraph 3 of Part 2B of the Pre-Emption Group’s 2022 Statement of Principles. The waiver granted by Resolution 12 is in addition to the waiver granted by Resolution 11 and itself has two parts: > The first part (at paragraph (b)(i) of Resolution 12) is limited to the allotment of shares for cash up to an aggregate nominal value of US$38,755,029 (which includes the sale on a non pre-emptive basis of any shares held in treasury), which represents a further 10% (approximately) of the Company’s total issued ordinary share capital as at 13 February 2024 (being the last practicable date prior to publication of this Notice of AGM). The first part of the waiver may only be used for an allotment of shares for cash for the purposes of financing (or refinancing, if the waiver is used within 12 months of the original transaction) a transaction that the Directors determine to be an acquisition or capital investment of a kind contemplated by the Pre-Emption Group’s 2022 Statement of Principles. > The second part of the waiver (at paragraph (b)(ii) of Resolution 12) applies to the allotment of shares for cash for the purposes of a follow-on offer when an allotment of shares has been made under the first part of the waiver. It is limited to the allotment of shares having an aggregate nominal value of up to 20% of the nominal value of any shares allotted under the first waiver contained at paragraph (b)(i) of Resolution 12. The follow-on offer must be determined by the Directors to be of a kind contemplated by the Pre-Emption Group’s 2022 Statement of Principles. The Directors confirm that they will follow the shareholder protections in Part 2B and the expected features of a follow-on offer in paragraph 3 of Part 2B of the Pre-Emption Group’s 2022 Statement of Principles. If the resolutions are passed, the waivers granted under Resolutions 11 and 12 will expire at the conclusion of the Annual General Meeting in 2025 or, if earlier, the close of business on 11 July 2025. The Directors have no present intention of exercising these authorities but are requesting the authorities in order to give them the flexibility to use shares, if so required, in connection with the proper development of the business. Resolution 13: Purchase of own shares by the Company The purpose of Resolution 13, which is proposed as a special resolution, is to renew the Company’s authority to make market purchases of its own shares, as permitted by the Act. The authority limits the total number of shares that could be purchased to a maximum of 155,020,119 (representing less than 10% of the issued share capital of the Company at 13 February 2024) and sets minimum and maximum prices. No shares were repurchased during 2023 and the Board has no intention of repurchasing shares in 2024. The authority sought under Resolution 13 will be exercised only if the Directors believe that to do so would result in an increase in earnings per share and would be likely to promote the success of the Company for the benefit of shareholders generally. The Directors’ current intention is that, in such circumstances, any shares so repurchased would be cancelled. The authority being sought under Resolution 13 would permit any shares so purchased either to be cancelled or held as treasury shares. To maximise its opportunities for access to the market, the Company may also consider using the same authority from shareholders to give irrevocable instructions to banks to enable any share repurchases to continue during the closed periods ahead of the quarterly publication of its results. If this were done, appropriate and timely announcements to the stock exchanges would be made. At 13 February 2024, the total number of shares under option that were outstanding under all of the Company’s share option plans was 1,173,685 representing 0.08% of the Company’s issued share capital at that date. This number of outstanding shares under option could potentially represent 0.10% of the issued share capital of the Company, if the Company were to purchase its own shares to the fullest possible extent of its authority from shareholders (both existing and being sought). This authority will only be valid until the conclusion of the Annual General Meeting in 2025 or the close of business on 11 July 2025, whichever is earlier. Resolution 14: Notice period for general meetings The purpose of Resolution 14, which is proposed as a special resolution, is to reduce the notice period required for a general meeting of the Company (other than an Annual General Meeting) to 14 clear days. Changes made to the Act by the Companies (Shareholders’ Rights) Regulations 2009 (the Shareholders’ Rights Regulations) increased the notice period required for general meetings of the Company to 21 days unless shareholders approve a shorter notice period, which cannot however be less than 14 clear days. Annual General Meetings will continue to be held on at least 21 clear days’ notice. The Company would like to preserve its ability to call general meetings on 14 clear days’ notice. The flexibility offered by Resolution 14 will be used where, taking into account the circumstances, the Directors consider that it is merited by the business to be considered at the meeting and it is thought to be in the interests of shareholders as a whole. The Company undertakes to meet the requirements for electronic voting under the Shareholders’ Rights Regulations before calling a general meeting on 14 clear days’ 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.

Members’ right to ask questions Any member participating in the meeting has the right to ask questions. The Company must answer any question relating to the business being dealt with at the meeting but no answer need be given if: (i) to do so would interfere unduly with the preparation for the meeting or involve the disclosure of confidential information; (ii) the answer has already been given on a website in the form of an answer to a question; or (iii) it is undesirable in the interests of the Company or the good order of the meeting that the question be answered. Registration of shareholder questions We encourage shareholders to register any questions they may have for the Board in advance of the digitally-enabled AGM so that all views are heard even if a shareholder is unable to participate on the day. Shareholders can register questions in advance until 17:00 (BST) 9 April 2024 at: www.astrazeneca.com/agm. You are still welcome to ask a question at the digitally-enabled AGM via the online platform irrespective of whether you have registered your question in advance. However, by registering your question in advance, you will help the Board to provide you with a comprehensive answer. If you are unable, or do not wish to participate in the AGM on the day, you may also choose to receive a written response to your question or have it put to the Board during the meeting. Full details of how to ask a question via the online platform during the meeting are set out from page 13. Please endeavour to keep your questions concise and relevant to the business of the AGM. Where we receive a number of questions covering the same topic, we may group these to address as many of your queries as possible. Additionally, we may remove supporting statements or paraphrase questions to ensure they are clear and concise. Entitlement to participate and vote Pursuant to Regulation 41 of the Uncertificated Securities Regulations 2001, only holders of ordinary shares entered in the register of members of the Company by 18:30 (BST) on 9 April 2024 (or their duly appointed proxies), or if this meeting is adjourned, in the register of members by 18:30 (BST) two days prior to any adjourned meeting, are entitled to participate or vote at the AGM in respect of the number of ordinary shares registered in their name at that time. Changes to the entries in the register of members after 18:30 (BST) on 9 April 2024, or if this meeting is adjourned, in the register of members after 18:30 (BST) two days prior to any adjourned meeting, shall be disregarded in determining the rights of any person to participate or vote at the AGM. Voting at the AGM All shareholders are encouraged to vote either in advance or on the day. You will be able to vote in one of three ways for each of the resolutions: ‘For’, ‘Against’ or ‘Vote Withheld’. Please note that a ‘Vote Withheld’ is not a vote in law and will not be counted in the calculation of votes ‘For’ and ‘Against’ each resolution. If you are a holder of shares listed on the Stockholm Nasdaq or of American Depositary Shares, you should follow the instructions set out in the specific documentation sent to you. If you hold via the AstraZeneca Sponsored Nominee, you should follow the instructions set out separately on page 11. If you hold shares through another nominee or brokerage account, you should follow the relevant voting instructions that have been provided to you. Voting before the meeting If you are a registered member of the Company, there are several ways to submit your voting instructions before the meeting, which are available from the publication date of this Notice of AGM: (1) Equiniti’s Shareview website; (2) appointment of proxies through CREST; or (3) by completing and returning a paper proxy form. Votes submitted electronically via Equiniti’s Shareview website, or via CREST, (options 1 and 2 above) should be registered by no later than 14:30 (BST) on 9 April 2024. After then, you will no longer be able to submit your proxy vote via Equiniti’s Shareview website or CREST. Paper proxy votes (option 3 above) must be received by no later than 9 April 2024. If you are voting by paper proxy, you are strongly encouraged to appoint the Chair of the AGM as your proxy. This means the Chair of the AGM will be able to vote on the day on your behalf, in accordance with your instructions. Paper proxy forms are available from Equiniti on request; you can call our shareholder helpline on +44 (0) 800 389 1580, or use any of Equiniti’s alternative contact details listed on the back page. Any shareholder that votes in advance of the meeting, in accordance with the voting instructions set out in this Notice of AGM, will have their votes cast at the meeting as per the instructions provided. Voting on the day Voting on the day will be available via the online platform once the Chair declares the poll open. It will remain open until the Chair closes voting at the end of the meeting. Holders of American Depositary Shares and holders of shares registered on Nasdaq Stockholm that have voted in advance will not be able to vote via the online platform. They will still be able to participate in, and ask questions during, the digitally-enabled meeting. Poll voting All resolutions will be put to a poll vote. This means that a shareholder has one vote for every share held and the votes of all shareholders who submit a proxy form in advance of the meeting are counted, even if the shareholder does not participate in the meeting. Entitlement to appoint proxies A registered member of the Company may appoint one or more proxies (who need not be a member of the Company) to exercise all or any of their rights to participate and to speak and vote at a meeting of the Company provided that each proxy is appointed to exercise the rights attached to a different share or shares held by the member. A member may only appoint a proxy by: > Going to the Shareview website, www.shareview.co.uk. > If you are a user of the CREST system (including CREST Personal Members), having an appropriate CREST message transmitted. > Completing and returning the form(s) of proxy accompanying this Notice of AGM. If an individual is appointed as a proxy to participate and to speak at the digitally-enabled AGM, the individual(s) appointed will be provided with a Shareholder Reference Number (SRN) and PIN. This will allow them to participate in the digitally-enabled AGM via the online platform. The registered member should ensure they share the joining instructions with their appointed proxy. You may not use any email address provided in this Notice of AGM to communicate with the Company for any purposes other than those expressly stated. Deadline for receipt of proxy form To be effective, the proxy form (or electronic appointment of a proxy) must be received by the Company’s registrar, Equiniti Registrars, not later than 14:30 (BST) on 9 April 2024, or if this AGM is adjourned, not less than 48 hours before the time for holding such adjourned meeting. 10 Notice of Annual General Meeting 2024 and Shareholders’ Circular General Notes

Appointment of proxies through Sharevote and Shareview websites Shareholders who would prefer to register the appointment of their proxy electronically via the internet can do so through the Sharevote website, www.sharevote.co.uk using their personal Authentication Reference Number (this is the series of numbers printed under the headings Voting ID, Task ID and Shareholder Reference Number on the Proxy Form or Voting Instruction Card). Alternatively, shareholders who have already registered with Equiniti Registrars’ online portfolio service, Shareview, can appoint their proxy electronically by logging on to their portfolio at www.shareview.co.uk by using their usual user ID and password. Once logged in, simply click ‘View’ on the ‘My Investments’ page, click on the link to vote and then follow the on-screen instructions. Full details and instructions on these electronic proxy facilities are given on the respective websites. Appointment of proxies through CREST CREST members who wish to appoint a proxy or proxies for the AGM, including any adjournment(s) thereof, through the CREST electronic proxy appointment service may do so by using the procedures described in the CREST Manual on the Euroclear website, www.euroclear.com. CREST personal members or other CREST sponsored members, and those CREST members who have appointed a voting service provider(s), should refer to their CREST sponsor or voting service provider(s) who will be able to take the appropriate action on their behalf. In order for a proxy appointment or instruction made using the CREST service to be valid, the appropriate CREST message (CREST Proxy Instruction) must be properly authenticated in accordance with Euroclear UK & Ireland Limited’s specifications and must contain the information required for such instructions, as described in the CREST Manual. The message, regardless of whether it relates to the appointment of a proxy or to an amendment to the instruction given for a previously appointed proxy, must, in order to be valid, be transmitted so as to be received by Equiniti Registrars (ID RA19) by the latest time for receipt of proxy appointments specified above. For this purpose, the time of receipt will be taken to be the time (as determined by the time stamp applied to the message by the CREST Applications Host) from which Equiniti Registrars is able to retrieve the message by enquiry to CREST in the manner prescribed by CREST. After this time, any change of instructions to a proxy appointed through CREST should be communicated to the proxy through other means. CREST members and, where applicable, their CREST sponsors or voting service providers should note that Euroclear does not make available special procedures in CREST for any particular messages. Normal system timings and limitations will therefore apply in relation to the input of CREST Proxy Instructions. It is the responsibility of the CREST member concerned to take (or, if the CREST member is a CREST personal member or sponsored member or has appointed a voting service provider(s), 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 service provider(s) are referred, in particular, to those sections of the CREST Manual concerning practical limitations of the CREST system and timings. The Company may treat a CREST Proxy Instruction as invalid in the circumstances set out in Regulation 35(5)(a) of the Uncertificated Securities Regulations 2001. Holders of ordinary shares in the AstraZeneca Nominee Service Holders of ordinary shares in the AstraZeneca Nominee Service may vote in advance via the Sharevote website (www.sharevote.co.uk), or, for holders that have registered with Equiniti Registrars’ online portfolio service, via the Shareview website, www.shareview.co.uk.

ADS holders should follow the voting instructions set out in the notice documents sent to them. As with prior years, ADS holders are encouraged to vote in advance of the AGM through the Depositary.

Any ADS registered holder wishing to vote at the AGM should not submit voting instructions in advance. Voting in advance will not prevent registered ADS holders from participating in the AGM via the online platform.

If a Nominated Person has no such proxy appointment right or does not wish to exercise it, they may, under any such agreement, have a right to give instructions to the shareholder as to the exercise of voting rights. The statement of the rights of shareholders in relation to the appointment of proxies above does not apply to Nominated Persons. The rights described above can only be exercised by shareholders of the Company.

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 Companies Act 2006.
