Letter from the Chair

Sir Dave Lewis Chair

"Haleon has delivered further progress this year, demonstrating the Group's strong potential. The Board look forward to engaging with shareholders during this year's AGM."

Haleon's 2025 AGM will be held at 3.00pm (BST) on Wednesday 28 May 2025. Consistent with Haleon's ways of working, this will again be a virtual meeting, broadcast under studio conditions from our London offices and accessed via the Lumi platform – https://meetings.lumiconnect.com/100-398-631-531. Further information on joining the Meeting is set out within this Notice.

The Board values shareholder participation in our AGM, and we have chosen a virtual approach in line with our Articles of Association and ways of working. With the significant majority of our share ownership situated outside of the UK, this format allows us to maximise engagement with all of our shareholders globally to participate in the AGM. Our approach is also in line with our responsible business ambitions by reducing the environmental impact of our AGM.

Business of the Meeting

This year we are proposing 22 resolutions which are set out for your consideration on pages 6 to 10 (inclusive).

Directors

Since the last AGM, we have welcomed a number of new Directors to the Board, including our new Chief Financial Officer, Dawn Allen. Dawn was appointed to the Board on 1 November 2024 and brings deep consumer and financial experience to the Board.

We have also welcomed three new Non-Executive Directors, Nancy Avila, Alan Stewart and Bláthnaid Bergin. Together, the new Non-Executive Directors strengthen the Board's collective expertise and breadth of skills, particularly in areas such as technology, cyber, consumer, finance and business transformation. The Directors' biographies, including details of their other significant appointments and responsibilities, are available on pages 59-61 of the Annual Report and on our website, www.haleon.com.

During the year, Tobias Hestler stepped down as Chief Financial Officer of Haleon. I would like to thank him for his significant contribution to the Board and his key role in establishing Haleon as a stand-alone business.

In October 2024, Deirdre Mahlan stepped down from the Board and was succeeded by Alan Stewart as Chair of the Audit & Risk Committee. I would like to thank Deirdre for her considerable contributions to the Board and for chairing the Audit & Risk Committee since Haleon's listing in July 2022.

In December 2024, following the reduction of Pfizer Inc.'s shareholding to below 20%, David Denton stepped down from the Board as Non-Executive Director and representative director of Pfizer. Following Pfizer's further shareholding reduction to below 10% in January 2025, Bryan Supran stepped down from the Board as Non-Executive Director and the remaining representative director of Pfizer in February 2025. I would like to thank them both for their insights and contributions to the Board.

In accordance with the UK Corporate Governance Code (the Code), all of the Board are standing for election or re-election at the 2025 AGM. The Board considers that each of the Directors continues to bring considerable knowledge, valuable skills and significant experience and that individually, and collectively, they make effective and important contributions to their respective roles. In line with the provisions of the Code, we have also included a statement setting out each Director's contributions and reasons for our recommendation for election or re-election on pages 4 and 5.

Voting

Your vote is important and we encourage all shareholders to vote during the Meeting via the Lumi platform or in advance of the Meeting by appointing the Chair, or person of your choice, as a proxy. Voting on all resolutions on the day of the AGM will be by way of a poll. The results of voting will be announced via a regulatory information service and published on our website at www.haleon.com as soon as practicable following the AGM. Please see pages 11 and 12 for further details on how to vote.

Asking questions

We recognise the AGM is an important opportunity for you as a shareholder to put your questions concerning the business of the Meeting to the Board. We encourage shareholders to submit their questions in advance by accessing the Lumi platform from 12.00pm (BST) on Monday 7 April 2025. The deadline for pre-submitted questions is 12.00pm (BST) on Tuesday 27 May 2025. We also welcome live questions on the day of the AGM via the Lumi platform.

Recommendations

The Board believes that Resolutions 1-22 (inclusive) are in the best interests of the Company, its shareholders and wider stakeholder group as a whole and unanimously recommend that you vote in favour of each of them, as they intend to do in respect of their own holdings.

On behalf of the Board, I thank you for your continued support of Haleon.

Yours sincerely

Sir Dave Lewis Chair 4 April 2025

Political donations

• 17 To authorise, for the purposes of Part 14 of the Companies Act 2006 (the Act), the Company and all companies which are its subsidiaries at any time, during the period for which this resolution has effect, to:
  • (a) make donations to political parties and/or independent election candidates not exceeding £50,000 in total;
  • (b) make donations to political organisations other than political parties not exceeding £50,000 in total; and
  • (c) incur political expenditure not exceeding £50,000 in total, provided that the aggregate amount of any such donations and expenditure shall not exceed £100,000 during the period beginning with the date of passing of this resolution and expiring at the end of the Company's AGM to be held in 2026 (or, if earlier, at the close of business on 30 June 2026).

Words, terms and expressions defined in Part 14 of the Act shall have the same meaning in this Resolution.

This Resolution seeks authority from shareholders for the Company and its subsidiaries to make donations to UK and/or EU political parties, other political organisations or independent electoral candidates, or to incur UK and/or EU political expenditure. It is the Company's policy not to make donations to political parties and the Company has no intention of altering this policy. However, as the definitions used in the Act are broad, it is possible that normal business activities, which might not be thought to be political donations or expenditure in the usual sense, could be caught. Accordingly, the Company is seeking this protective authority to ensure that it does not inadvertently commit any breaches of the Act through the undertaking of routine activities which would not normally be considered to result in the making of political donations.

Authority to allot shares

• 18 To authorise the Directors generally and unconditionally in accordance with section 551 of the Act, in substitution for all subsisting authorities, to allot shares in the Company and to grant rights to subscribe for or to convert any security into shares in the Company:
  • (a) up to an aggregate nominal amount of £30,100,000 (representing 3,010,000,000 ordinary shares); and
  • (b) comprising equity securities (as defined in the Act) up to an aggregate nominal amount of £60,210,000, representing approximately 6,021,000,000 ordinary shares (including within such limit the nominal value of any shares issued or rights granted under paragraph (a) above) in connection with an offer to:
    • (i) holders of ordinary shares in proportion (as nearly as may be practicable) to their existing holdings; and
    • (ii) holders of other equity securities if this is required by the rights of those securities or, if the Directors consider it necessary, as permitted by the rights of those securities;

and so that the Directors may impose any limits or restrictions and make any arrangements which they consider necessary or appropriate to deal with treasury shares, fractional entitlements, record dates, legal, regulatory or practical problems in, or under the laws of, any territory, or any matter whatsoever.

These authorities shall apply until the end of the Company's AGM to be held in 2026 (or, if earlier, at the close of business on 30 June 2026) but, in each case, so that the Company may make offers or enter into any agreements during the relevant period which would, or might, require relevant securities to be allotted after the authority expires and the Directors may allot relevant securities in pursuance of such offer or agreement as if the authority conferred hereby had not expired.

The amount in limb (a) is equivalent to approximately 33% of the issued share capital of the Company and the amount in limb (b) is equivalent to approximately 66% of the issued share capital of the Company, in each case excluding treasury shares, as at the last practicable date.

The Directors have no present intention to exercise the authority sought under this Resolution, except to fulfil the Company's obligations under its employee share plans. As at the last practicable date, the Company had 4,080,205 ordinary shares held as treasury shares which represents approximately 0.0005% of the Company's total issued ordinary share capital (excluding treasury shares) as at that date.

    • (ii) when any allotment of equity securities is or has been made pursuant to paragraph (a) (i) of this Resolution 20 (a paragraph (a) (i) allotment), the allotment of equity securities up to an aggregate nominal amount equal to 20% of the nominal amount of that paragraph (a) (i) allotment, provided that any allotment pursuant to this paragraph (a) (ii) shall be used only for the purposes of making a follow-on offer which the Directors determine to be of a kind contemplated by paragraph 3 of Section 2B of the Statement of Principles on Disapplying Pre-Emption Rights published by the Pre-Emption Group in 2022;
  • (b) applies in relation to a sale of shares which is an allotment of equity securities by virtue of section 560(3) of the Act as in the first paragraph of this Resolution the words "under the authority given by Resolution 18" were omitted; and
  • (c) shall expire at the end of the Company's next AGM (or if earlier, at the close of business on 30 June 2026), but, in each case, prior to its expiry the Company may make offers, and enter into agreements, which would, or might, require equity securities to be allotted (and treasury shares to be sold) after the authority ends and the Directors may allot equity securities under any such offer or agreement as if the authority had not expired.

Resolutions 19 and 20 are to be voted on as special resolutions and would, subject to the passing of Resolution 18, give the Directors power to allot equity securities (or sell any treasury shares) for cash without first offering them to existing shareholders in proportion to their existing holdings on the basis set out below.

In line with the latest Statement of Principles published by the Pre-Emption Group in 2022, Resolution 19 contains a three-part waiver. The first part of Resolution 19 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 of Resolution 19 is limited to the allotment of shares for cash up to an aggregate nominal value of approximately 10% of the Company's issued ordinary share capital (excluding ordinary shares held in treasury) as at the last practicable date (which includes the sale on a non-pre-emptive basis of any treasury shares). The third part of Resolution 19 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. 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 waiver under Resolution 20 is in addition to that proposed by Resolution 19 and has two parts. The first part is limited to the allotment of shares for cash up to an aggregate nominal value of approximately a further 10% of the Company's issued ordinary share capital (excluding ordinary shares held in treasury) as at the last practicable date (which includes the sale on a non-pre-emptive basis of any treasury shares). The first part of the waiver may only be used for an allotment of shares for cash for the purposes of financing (or re-financing, if the waiver 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 Pre-Emption Group's 2022 Statement of Principles. The second part of the waiver 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.

The Directors confirm that in the instance of a 'follow-on' offer, the Company intends to include the expected features and follow the shareholder protections outlined in Section 2B of the Pre-Emption Group's 2022 Statement of Principles.

At present, the Board does not have a current intention to exercise the powers in Resolution 19 and 20, but the Board considers they are appropriate and would offer the Company flexibility if needed to finance potential business opportunities or to conduct a pre-emptive offer beyond the requirements of the statutory pre-emption provisions.

Notice of general meetings

21 To authorise the Directors to call general meetings (other than an AGM) on not less than 14 clear days' notice. Under the Act, the notice period required for all general meetings of the Company is 21 clear days. However, shareholders can agree to approve a shorter notice period for general meetings that are not annual general meetings, 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 confirms that it will endeavour to give as much notice as practicable when calling a general meeting. The shorter notice period would not be used as a matter of routine, but only where the flexibility is merited by the business of the general meeting to be held and is thought to be to the advantage of shareholders as a whole. If the Company calls a general meeting on less than 21 clear days' notice, the Company will provide a means for all shareholders to vote electronically for that meeting.

The authority sought under Resolution 21, which will be proposed as a special resolution, will expire on the conclusion of the 2026 AGM (or, if earlier, at the close of business on 30 June 2026).

Purchase of own shares

• 22 To authorise the Company generally and unconditionally pursuant to section 701 of the Act to make market purchases (as defined in section 693(4) of the Act) of ordinary shares provided that:
  • (a) the maximum number of ordinary shares which may be purchased is 903,000,000 which represents approximately 10% of the issued ordinary share capital of the Company, excluding treasury shares, on the last practicable date;
  • (b) the minimum price (excluding stamp duty and expenses) which may be paid for each such share is the nominal value of such share;
  • (c) the maximum price (excluding stamp duty and expenses) which may be paid for each such share is the higher of:
    • (i) an amount equal to 5% above the average of the middle market quotations for an ordinary share as derived from the Daily Official List of the London Stock Exchange for the five business days immediately preceding the day on which the relevant share is purchased; and
    • (ii) 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; and
  • (d) the authority hereby conferred shall apply until the conclusion of the 2026 AGM (or, if earlier, at the close of business on 30 June 2026) (except in relation to the purchase of shares the contracts for which are concluded before such expiry and which are executed wholly or partly after such expiry), unless such authority is renewed prior to such time.

Notice of 2025 Annual General Meeting and Explanatory Notes continued

In certain circumstances, it may be advantageous for the Company to make market purchases of ordinary shares and the Directors consider it to be desirable for this general authority to be available to provide flexibility in the management of the Company's capital resources. On-market purchases of the Company's own shares will be made only if to do so would be in the best interests of the Company and its shareholders generally. If the Directors make use of this authority, any shares purchased may be held as treasury shares with a view to possible re-issue at a future date, be used to satisfy awards under share incentive arrangements or be cancelled.

Resolution 22 will be proposed as a special resolution and seeks shareholder approval for the Company to make market purchases of its own ordinary shares of up to approximately 10% of the issued share capital as at the last practicable date, and specifies the minimum and maximum price at which the ordinary shares may be bought.

Further detail in relation to Resolution 22 can be found in the Appendix on page 16.

Voting & Shareholder FAQs

Why is this a virtual meeting?

The virtual approach is in line with our ways of working, supports our responsible business ambitions and recognises that the significant majority of our shareholders are based outside of the UK. This format allows us to maximise the engagement opportunity for all our shareholders globally to participate in the AGM. Haleon has the facility within its Articles of Association to host a virtual AGM.

Entitlement to join the AGM

To join the AGM, submit questions and vote (and for the purpose of the determination by the Company of votes they may cast), shareholders must be entered on the Company's register of members at 6.30pm (BST) on Friday 23 May 2025, or, in the event of an adjournment, 6.30pm (BST) on the date which is two business days before the time of the adjourned meeting.

Members may cast votes only in respect of shares of which they were registered holders at such time, and changes to the register of members after the relevant deadline shall be disregarded in determining the rights of any person to attend and vote at the AGM.

For full details relating to voting and participation rights of shareholders, please refer to the Articles of Association, available on the Company's website at: www.haleon.com

How do I vote?

Shareholders, registered ADS holders and their proxies or corporate representatives can vote at the AGM via the Lumi platform (see page 3 for further details) or by submitting their vote in advance.

Proxies

If you are a registered shareholder and cannot participate in the AGM, you may appoint the Chair of the AGM to vote on your behalf or any other person (a proxy) to exercise your rights, including to attend, speak and vote on your behalf. A shareholder of the Company is entitled to appoint one or more proxies in relation to the Meeting, provided that each proxy is appointed to exercise the rights attached to a different share or shares held by that member. A proxy need not be a member of the Company and you can appoint the Chair of the AGM or any other person to exercise your rights. If you appoint a proxy without indicating how the proxy should vote on a particular matter, the proxy may exercise their discretion as to whether, and if so how, they vote on that matter. The appointment of a proxy online, return of a completed proxy form, other instrument or any CREST Proxy Instruction will not prevent a member from participating in the AGM electronically and submitting a vote online at the AGM if they wish to do so.

All advance proxy votes, regardless of how they are cast, must be returned by 3.00pm (BST) on Friday 23 May 2025. If you return both paper and electronic instructions, those received last by Equiniti before 3.00pm (BST) on Friday 23 May 2025 will take precedence. Electronic communication facilities are available to all shareholders.

Further information about appointing a proxy can be found on your proxy card. Whether or not you intend to participate in the AGM, we encourage you to appoint the Chair of the AGM, as opposed to any other person, to act as your proxy to ensure your vote is counted (if, for instance, you or that other person is not able to participate in the Meeting).

How do I appoint a proxy?

Holders of ordinary shares can appoint a proxy and register voting instructions:

• online, by completing the proxy form via a Shareview portfolio at www.shareview.co.uk. It is free to register for a Shareview portfolio;
• by completing and returning the enclosed proxy card (if one has been sent to you), using the pre-paid envelope provided, to our Registrar, Equiniti; or
• via CREST or the Proxymity platform (see below for further information).

Your instructions must be received by no later than 3.00pm (BST) on Friday 23 May 2025 or your proxy appointment will not be valid. Proxy instructions can only be submitted as stated above.

Proxy votes cannot be submitted by any other means unless expressly permitted by the Company or our Registrar, Equiniti.

Appointment of proxies through CREST or Proxymity

CREST members may appoint proxies for the AGM and any adjournment through the CREST electronic proxy appointment service by using the procedures described in the current version of the CREST Manual (available via www.euroclear.com). CREST personal members or other CREST sponsored members, and those CREST members who have appointed a voting service provider or providers, should refer to their CREST sponsor or voting service provider(s), who will be able to take appropriate action on their behalf.

All messages, relating to the appointment of a proxy or an instruction to a previously appointed proxy, must be transmitted so as to be received by the issuer's agent, Equiniti ID RA19 by 3.00pm (BST) on Friday 23 May 2025. It is the responsibility of the CREST member concerned to take 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 providers are referred, in particular, to those sections of the CREST Manual concerning practical limitations of the CREST system and timings. 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.

If you are an institutional investor, you may be able to appoint a proxy electronically via the Proxymity platform, a process which has been agreed by the Company and approved by the registrar. For further information regarding Proxymity, please go to www.proxymity.io. Your proxy must be lodged by 3.00pm (BST) on Friday 23 May 2025 in order to be considered valid.

Before you can appoint a proxy via this process, you will need to have agreed to Proxymity's associated terms and conditions. It is important that you read these carefully as you will be bound by them, and they will govern the electronic appointment of your proxy.

Voting & Shareholder FAQs continued

Can I appoint a corporate representative?

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

Duly appointed proxies and corporate representatives

If you plan to participate in the AGM as a proxy or corporate representative, please contact our Registrar, Equiniti, on meetingtech.help@equiniti.com before 3.00pm (BST) on Tuesday 27 May 2025 to obtain details on how to access the Meeting. If you plan to participate as a proxy, the shareholder appointing you must first submit their proxy appointment before you contact Equiniti. Equiniti's contact details are on page 14.

American Depositary Shares (ADS) Holders

Registered holders of the Company's ADSs evidenced by American Depositary Receipts will receive a separate Notice of Meeting and guide, which provides details of how to participate in the Meeting. They may vote online through the Depositary until 11.59pm (EDT) on Wednesday 21 May 2025. Voting instruction forms need to be received by 8.00am (EDT) on Thursday 22 May 2025. The submission of instructions will not prevent holders from participating in the AGM, but they will not be able to vote again or change their vote at the AGM. Any registered ADS holder wishing to vote at the AGM should not submit voting instructions in advance.

If you have any queries or are an ADS holder and do not receive a separate Notice of Meeting and guide, please contact J.P. Morgan using the contact details on page 14.

Beneficial owners who hold ADSs in a street name, should contact their bank, broker or nominee for information on how to vote their ADSs.

How are the votes counted and where can I find the results?

Voting on all Resolutions will be by a poll, as required by the Articles of Association. This is a more transparent method of voting as shareholder votes are counted according to the number of shares held. In accordance with UK listing requirements, we have included a 'vote withheld' option when voting. A vote withheld is not a vote in law and will not be counted in calculation of the proportion of votes 'for' or 'against' a Resolution.

The total of the votes cast by shareholders 'for' or 'against' or 'withheld' on each Resolution will be announced via a regulatory information service and published on www.haleon.com as soon as practicable following the AGM.

How will I know if there are changes to the arrangements for the AGM?

Our corporate website is the principal means we use to communicate with shareholders and we encourage you to monitor our website www.haleon.com for any potential changes to the information or arrangements included in this Notice of AGM. Where appropriate, we may also notify shareholders by way of a regulatory information service announcement.

Help with my shareholding Ordinary shares

For information on a range of shareholder services, including enquiries concerning individual shareholdings, notification of a shareholder's change of address and amalgamation of shareholder accounts (in order to avoid duplicate mailing of shareholder communications), shareholders should contact the Company's Registrar, Equiniti, using the contact details on page 14.

ADS

Our Depositary Bank for ADS holders is J.P. Morgan and the Transfer Agent in the United States of America is EQ. They look after our ADS register and are responsible for ensuring that ADS shareholder details are recorded accurately. You should contact J.P. Morgan for anything related to your registered ADS shareholding using the contact details on page 14.

Other

Beneficial owners who hold ordinary shares or ADSs in a nominee or alternative vehicle, should contact their bank, broker or nominee for support with respect of their shareholding.

Appendix

Additional information in relation to Resolution 22

Background to Resolution 22

The Board wishes to continue to have maximum flexibility in managing the Company's capital resources and intends to seek shareholder approval of a number of resolutions relating to the Company's share capital. This includes renewing the authority for the Company to make market purchases of ordinary shares (Resolution 22).

In March 2025 Pfizer reduced its stake in Haleon to nil. In light of this, Haleon will no longer seek re-approval of the off-market buyback contract as it has at previous AGMs.

2024 buyback activity

During 2024, the Board utilised the on-market and off-market buyback authorities approved at the 2023 and 2024 AGMs respectively. In February 2024, the Company announced the allocation of £500m to share buybacks in 2024.

The buybacks were executed in three phases. Firstly in March 2024, Haleon participated in Pfizer's secondary global offering, completing an off-market share purchase of 102,272,727 ordinary shares totalling c.£315m. This transaction marked a significant step in Pfizer's first reduction of its stake in Haleon following the Company's listing in July 2022. Subsequently, in August 2024, the Company initiated an on-market share buyback programme purchasing a further c.£70m-worth of shares (representing 18,413,907 ordinary shares) and finally, completing a further off-market share purchase of 30,161,278 ordinary shares from Pfizer in October 2024 totalling c.£114.6m. All shares purchased in relation to the £500m capital allocation were cancelled.

In addition, a further c.£115.4m-worth of shares (representing 30,365,037 ordinary shares) were purchased from Pfizer in October 2024 to satisfy the Company's obligations under its employee share schemes. These shares were held as treasury shares.

Of the shares bought back and cancelled in the 2024 calendar year, ordinary shares purchased under the 2023 AGM authority represented approximately 1.13% and ordinary shares purchased under the 2024 AGM authority represented approximately 0.87% of Haleon's issued share capital, excluding shares held in treasury as at the last practicable date.

2025 buyback activity

On 27 February 2025, the Company announced the allocation of £500m to share buybacks in 2025.

In March 2025, Haleon made an off-market purchase of 44,155,844 ordinary shares from Pfizer totalling c.£170m. All shares purchased were cancelled. This represented a portion of the £500m of capital allocated to share buybacks announced in February 2025.

On 28 March 2025, Haleon announced the launch of a share buyback programme for an aggregate total of £330m. This represents the remainder of the £500 million allocated to share buybacks in 2025 announced on 27 February 2025.

The first tranche of the buyback programme began on 28 March 2025 for an aggregate consideration of up to £200 million. All shares purchased by the Company under the first tranche will be cancelled and the purpose is to reduce the Company's share capital.

As at the last practicable date, 3,068,525 ordinary shares have been purchased under this programme.

It is currently anticipated that the Company will conduct share buybacks if the opportunity arises and it is considered to be in the best interests of the Company and its shareholders as a whole to do so at the relevant time.

Further information in relation to Haleon's on-market and off-market buybacks is available at www.haleon.com/investors/ shareholder-information/share-buybacks.

Effect of the exercise in full of Resolution 22

It is the Board's current intention that, if any shares are purchased under Resolution 22, any such shares may be held as treasury shares with a view to possible re-issue at a future date, used to satisfy awards under share incentive arrangements or be cancelled.

As at the last practicable date, the total number of conditional awards and options over ordinary shares outstanding was approximately 115 million, representing approximately 1.27% of the issued share capital (excluding treasury shares). If the authority to purchase shares under Resolution 22 was exercised in full, the total number of conditional awards and options to subscribe for ordinary shares outstanding as at the last practicable date would, assuming no further ordinary shares are issued, represent approximately 1.41% of the issued share capital (excluding treasury shares).

As at the last practicable date, no warrants over ordinary shares in the capital of the Company are in existence and 4,080,205 ordinary shares are held as treasury shares.
