Highlights

Experian plc Highlights

"FY24 growth was at the top end of our expectations. Total revenue growth from ongoing activities was 8% at actual exchange rates and 7% at constant exchange rates. Organic revenue growth was 6%, we raised margins and delivered US\$1.9bn of operating cashflow.

"For FY25, we expect further strategic progress and expect to deliver organic revenue growth in the range of 6-8%. We also expect good margin expansion, in the range of 30-50 basis points, at constant currency.

"Looking further ahead, we expect the combination of economic recovery, continued new product and vertical market expansion as well as productivity gains from technology cloud transition to elevate our financial performance. We anticipate strong organic revenue growth, good margin accretion and reduced levels of capital expenditure."

Letter from the Chair

7 June 2024 To holders of ordinary shares

Dear Shareholder

Annual General Meeting: 17 July 2024

I am writing with details of our Annual General Meeting (AGM), which will be held on Wednesday 17 July 2024 at 9.30am at The Merrion Hotel, Upper Merrion Street, Dublin 2, D02 KF79, Ireland.

We regard the AGM as an important forum for engaging with shareholders, particularly private shareholders, and we welcome your questions. If you cannot attend in person, you may submit questions about the AGM's business in advance, by email to agmquestions@experianplc.com or on the reply paid question card attached to the proxy form. We will consider all questions and, if appropriate, address them at the AGM, via Experian's website (experianplc.com) or individually.

The notice of meeting and notes are set out on pages 4 to 7 of this document. An explanation of the resolutions being proposed at the meeting is set out in Appendix 1. Voting will be taken on a poll, except for any procedural resolution which may be taken on a show of hands. I encourage you to use your vote by attending in person, voting electronically online or completing and returning a proxy form by post. You may place your proxy form in an envelope addressed to the Company's share registrars. A postage stamp is not needed if you post the form in the UK and, should shareholders wish, proxy forms may be placed in an envelope and addressed to the Company's registrars. You should return your completed form as soon as possible but it must arrive no later than 9.30am on Monday 15 July 2024. Returning a proxy form or voting electronically will not prevent you from attending the meeting in person. If you wish to vote electronically, you can do so by registering for the Link Share Portal service, at experianplc.com/ shares, or as otherwise outlined in this notice of meeting.

Further details of how to vote are included in the 'Information for shareholders' section at the end of this document. Shareholders entitled to attend, speak and vote at the AGM may appoint a proxy to exercise their rights in their place. You may appoint more than one proxy, provided that you appoint each proxy to exercise the rights attached to different shares.

The directors have announced a second interim dividend of 40.50 US cents per ordinary share, to be paid on 19 July 2024 to holders of the Company's ordinary shares on 21 June 2024. To ensure that certain UK shareholders have the same tax treatment on their dividend as if the Company was based in the UK, we have Income Access Share arrangements in place. The mechanics of these arrangements make it impractical to submit a proposed dividend for approval at the AGM, but the Board has no plans to announce any additional dividend in respect of the year ended 31 March 2024.

The directors consider that all the resolutions to be put to the AGM are in the best interests of the Company and its shareholders as a whole. Accordingly, the directors unanimously recommend that you vote in favour of all resolutions, as they intend to do in respect of their own beneficial shareholdings.

Yours faithfully

Mike Rogers Chair

Notes

• 1. The Company, pursuant to the Companies (Uncertificated Securities) (Jersey) Order 1999, specifies that only those persons entered on the register of members of the Company as at close of business on 15 July 2024 shall be entitled to attend or vote at the meeting in respect of the number of shares registered in their name at that time. Changes to entries on the register of members after close of business on 15 July 2024 shall be disregarded in determining the rights of any person to attend or vote at the meeting. If the meeting is adjourned to a time not more than 48 hours after the specified time applicable to the original meeting, that time will also apply for the purpose of determining the entitlement of members to attend and vote (and for the purpose of determining the number of votes they may cast) at the adjourned meeting. If, however, the meeting is adjourned for a longer period then, to be so entitled, members must be entered on the Company's register of members at close of business on the day two days prior to the adjourned meeting or, if the Company gives notice of the adjourned meeting, at the time specified in that notice. Changes to entries in the register of members after close of business on the relevant date shall be disregarded in determining the rights of any person to attend or vote at the meeting.
• 1. The following documents will be available for inspection at the Company's registered office (22 Grenville Street, St Helier, Jersey, JE4 8PX, Channel Islands) and at the offices of Linklaters LLP (One Silk Street, London, EC2Y 8HQ, United Kingdom) during normal business hours on weekdays (Saturdays and public holidays excluded) up to and including the date of the Annual General Meeting and at the place of the Annual General Meeting from 9.15am on the day of the meeting until its conclusion:
  2. (i) copies of the service contracts of the executive directors; and
  3. (ii) copies of the letters of appointment of all directors.
• 1. A member entitled to attend and vote at the meeting may appoint a proxy or proxies to attend and, on a poll, to vote in their place. A proxy need not be a member of the Company. If shareholders want their proxy to speak on their behalf, they must appoint someone other than the Chair as their proxy. A shareholder may appoint more than one proxy, provided that the total number of such proxies shall not exceed the total number of shares carrying an entitlement to attend such meeting held by such member. The appointment of a proxy will not preclude members entitled to attend and vote at the meeting (or at any adjournment(s) of the meeting) from doing so in person if they so wish. Unless otherwise indicated on the Form of Proxy, CREST, Proxymity or any other electronic voting instruction, the proxy will vote as they think fit or, at their discretion, withhold from voting.
• 1. A shareholder which is a corporation and which wishes to be represented at the meeting by a person with authority to speak and vote (a 'corporate representative') must appoint such a person by resolution of its directors or other governing body. A corporate representative has the same powers on behalf of the corporation they represent as that corporation could exercise if it was an individual member of the Company.
• 1. Any person to whom this notice is sent who is a person nominated to enjoy information rights (a 'nominated person') may, under an agreement between themselves and the shareholder by whom they were nominated, have a right to be appointed (or to have someone else appointed) as a proxy for the meeting. Alternatively, if a nominated person has no such right, or does not wish to exercise it, they may, under any such agreement, have a right to give instructions to the relevant shareholder as to the exercise of voting rights.
• 1. The statement of the rights of shareholders in relation to the appointment of proxies in paragraph 3 above does not apply to nominated persons. The rights described in that paragraph can only be exercised by shareholders of the Company.
• 1. To be valid, an appointment of proxy must be returned using one of the following methods:
  2. (i) by sending a proxy form (together, if appropriate, with the power of attorney or other written authority under which it is signed or a certified copy of such power or authority) to Link Market Services (Jersey) Limited, c/o Link Group, FREEPOST PXS 1, Central Square, 29 Wellington Street, Leeds, LS1 4DL, United Kingdom; or
  3. (ii) in the case of members who have registered for the Link Share Portal service with the Company's registrars, by logging onto their portfolio at experianplc.com/shares, and following the voting instructions, shareholders will be able to register their proxy online. If requested, the Company's registrars will send an acknowledgement that the online proxy appointment has been lodged with them; or
  4. (iii) electronically via the Company registrar's app LinkVote+. The app is free to download via the Apple App Store or Google Play, and is compatible with smartphones and tablets. Via LinkVote+, shareholders can submit proxy votes as the LinkVote+ app is integrated with the Link Share Portal service; or
  5. (iv) in the case of CREST members, by utilising the CREST electronic proxy appointment service; or
  6. (v) institutional investors may be able to appoint a proxy electronically via the Proxymity platform, a process which has been approved by the registrars. For further information regarding Proxymity, please go to proxymity.io. Your proxy must be lodged by 9.30am on 15 July 2024 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. 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,

and in each case the appointment of proxy (together with any relevant power/authority) must be received (or, in the case of the appointment of a proxy through CREST, retrieved by enquiry to CREST in the manner prescribed by CREST) by the Company's registrars not later than 48 hours before the time appointed for holding the meeting. 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.

• 1. CREST members who wish to appoint a proxy or proxies through the CREST electronic proxy appointment service may do so for the meeting and any adjournment(s) thereof by using the procedures described in the CREST Manual available at 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(s) 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 (a 'CREST Proxy Instruction') must be properly authenticated in accordance with Euroclear UK & International Limited's specifications and must contain the information required for such instructions, as described in the CREST Manual available at euroclear.com. The message, regardless of whether it constitutes the appointment of a proxy or an amendment to the instruction given to a previously appointed proxy must, in order to be valid, be transmitted so as to be received by the issuer's agent (ID RA10) by the latest time(s) for receipt of proxy appointments specified in this notice of meeting. 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 Applications 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 by other means. CREST members and, where applicable, their CREST sponsors or voting service provider(s) should note that Euroclear UK & International Limited 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(s) 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.
• 1. The Company may treat as invalid a CREST Proxy Instruction in the circumstances set out in Article 34 of the Companies (Uncertificated Securities) (Jersey) Order 1999.
• 1. When two or more valid but differing proxy appointments are received in respect of the same share for use at the same meeting or poll, the one which is last received (regardless of its date or of 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.
• 1. As at 24 May 2024 (being the last practical day prior to publication of the notice of meeting), the Company's issued share capital consisted of 972,191,527 ordinary shares of 10 US cents each with voting rights and 20 deferred shares of 10 US cents each which have no voting rights. As at 24 May 2024, the Company held 54,008,546 shares in treasury. Therefore, the total voting rights in the Company as at 24 May 2024 was 918,182,981.
• 1. Any member attending the meeting has the right to ask questions. The Company must cause to be answered any such question relating to the business being dealt with at the meeting but no such answer need be given if (a) to do so would interfere unduly with the preparation for the meeting or involve the disclosure of confidential information, (b) the answer has already been given on a website in the form of an answer to a question, or (c) it is undesirable in the interests of the Company or the good order of the meeting that the question be answered. Any member may submit questions about the AGM's business in advance, by email to agmquestions@experianplc. com or on the reply paid question card attached to the proxy form. We will consider all questions and, if appropriate, address them at the AGM, via Experian's website (experianplc.com) or individually.
• 1. A copy of this notice and other relevant shareholder information can be found at experianplc.com.

Appendix 1

Explanatory notes in relation to the resolutions to be proposed at the Annual General Meeting.

Resolutions 1 to 16 will each be proposed as an ordinary resolution that will be passed if more than 50% of the votes cast are in favour of the resolution. Resolutions 17, 18 and 19 will each be proposed as a special resolution that will be passed if not less than two-thirds of the votes cast are in favour of the particular resolution.

Resolution 1

The directors are required to present to the meeting the Annual Report and financial statements of the Company for the year ended 31 March 2024 together with the report of the auditor.

Resolution 2

Resolution 2 is an advisory shareholder vote on the Report on directors' remuneration contained in the Annual Report (excluding the Directors' remuneration policy set out on pages 156 to 159 of the Annual Report) and financial statements of the Company for the year ended 31 March 2024, to provide shareholder feedback to the Board.

Resolutions 3 to 13

In accordance with the UK Corporate Governance Code, all members of the Board will retire and, being eligible, will offer themselves for re-election.

As more fully described in the Corporate governance report in the Annual Report and financial statements of the Company for the year ended 31 March 2024, an internal performance review of the Board was carried out during the year ended 31 March 2024. The review concentrated on the progress with last year's areas of focus. There were also separate meetings between each director proposed for re-election and the Chair in relation to their individual performance. The Senior Independent Director evaluated the Chair, taking into account the input from other directors.

The Board concluded that it and the committees were operating effectively, and the Board agreed new focus areas for FY25. The Board is satisfied that each of the directors retiring and submitting themselves for re-election at the Annual General Meeting contributes effectively and is important to the long-term sustainable success of the Company. Biographical details of the directors proposed for re-election, including details of their skills and experience, are set out in Appendix 2.

Resolution 14

An auditor has to be appointed at each Annual General Meeting. KPMG LLP has advised of its willingness to stand for re-appointment as the auditor of the Company.

Resolution 15

The remuneration of the auditor may be fixed by the directors or the Company in general meeting. The usual practice is for shareholders to resolve at the Annual General Meeting that the directors decide on such remuneration.

Resolution 16

The purpose of resolution 16 is to renew the directors' authority to allot new shares and other relevant securities, this year up to an aggregate nominal value of US\$30,606,099, which is equivalent to approximately one-third of the total issued ordinary share capital of the Company, exclusive of treasury shares, as at 24 May 2024.

At 24 May 2024, the Company held 54,008,546 ordinary shares in treasury.

The authority sought in resolution 16 is in substitution for all existing authorities, granted in the Company's articles of association or otherwise, and without prejudice to previous allotments made under such existing authorities. The authority will expire at the conclusion of the Annual General Meeting to be held in 2025 or, if earlier, 16 October 2025.

Resolutions 17 and 18

The UK Pre-Emption Group's Statement of Principles, as updated in November 2022, supports the annual disapplication of pre-emption rights in respect of allotments of shares and other equity securities, and sales of treasury shares for cash, representing no more than 10% of issued ordinary share capital (exclusive of treasury shares), without restriction as to the use of proceeds of those allotments.

Accordingly, the purpose of limb (a) of resolution 17, which is conditional on the passing of resolution 16 and will be proposed as a special resolution, is to authorise the directors to allot equity securities (as defined in the Company's articles of association) wholly for cash, or sell treasury shares for cash, without first offering those equity securities or treasury shares pro rata to existing shareholders, up to an aggregate nominal amount of US\$9,181,829, representing approximately 10% of the Company's issued ordinary share capital, exclusive of treasury shares (and 9.44% of the Company's issued ordinary share capital, inclusive of treasury shares), as at 24 May 2024, the latest practical date before publication of this notice.

The UK Pre-Emption Group's Statement of Principles also supports the annual disapplication of pre-emption rights in respect of allotments of shares and other equity securities, and sales of treasury shares for cash, representing no more than an additional 10% of issued ordinary share capital (exclusive of treasury shares), to be used only in connection with an acquisition or specified capital investment. The UK Pre-Emption Group's Statement of Principles defines "specified capital investment" as meaning one or more specific capital investment related uses for the proceeds of an issue of equity securities, in respect of which sufficient information regarding the effect of the transaction(s) and (where appropriate) the profits attributable to them, is made available to shareholders to enable them to reach an assessment of the potential return.

Accordingly, the purpose of limb (a) of resolution 18, which is conditional on the passing of resolution 16 and will be proposed as a special resolution, is to authorise the directors to allot equity securities (as defined in the Company's articles of association) wholly for cash, or sell treasury shares for cash, without first offering those equity securities pro rata to existing shareholders, up to a further nominal amount of US\$9,181,829, representing approximately 10% of the Company's issued

ordinary share capital, exclusive of treasury shares (and 9.44% of the Company's issued ordinary share capital, inclusive of treasury shares), as at 24 May 2024, the latest practical date before publication of this notice, only in connection with an acquisition or specified capital investment which is announced contemporaneously with the allotment or sale, or which has taken place in the preceding twelve-month period and is disclosed in the announcement of the issue. If the authority given in resolution 18 is used, the Company will publish details of the placing in its next Annual Report.

The UK Pre-Emption Group's Statement of Principles published in November 2022 introduces the concept of "follow-on" offers to help existing and retail investors to participate in equity issues. This is in line with the recommendations for improving capital raising processes which were made by the UK Secondary Capital Raising Review in July 2022.

The purpose of limb (b) of Resolution 17 and limb (b) of Resolution 18 is to give the directors the flexibility to make a follow-on offer.

The features of follow-on offers which are set out in the Statement of Principles (in section 2B, paragraph 3) include an individual monetary cap of not more than £30,000 per ultimate beneficial owner, limits on the number of equity securities allotted (or treasury shares sold) in any follow-on offer (not more than 20% of the number of equity securities allotted (or treasury shares sold) in the original offer), and limits on the price (equal to, or less than, the offer price in the original offer). The directors intend to adhere to the provisions in the UK Pre-emption Group's Statement of Principles for any follow-on offers made, as far as practicable.

The maximum nominal amount of equity securities which can be allotted (or treasury shares sold) in a follow-on offer is US\$3,672,731. This amount is in addition to the amounts authorised for the general use authority and the authority for acquisitions and specified capital investments described above, and, in total, is equivalent to 4% of the total issued ordinary share capital of the Company excluding treasury shares and approximately 3.78% of the total issued ordinary share capital of the Company including treasury shares, as at 24 May 2024.

The Board confirms that it intends to follow the shareholder protections set out in section 2B of the UK Pre-Emption Group's Statement of Principles and, for any follow-on offer made, the expected features set out in paragraph 3 of section 2B of the UK Pre-Emption Group's Statement of Principles.

If granted, the authorities in resolutions 17 and 18 will expire on the earlier of 16 October 2025 and the conclusion of the Annual General Meeting to be held in 2025.

The Board considers that it is in the best interests of the Company and its shareholders generally that the Company should have the flexibility conferred by resolutions 17 and 18 to make small issues of shares for cash, as suitable opportunities arise. Resolutions 18 and 19 have been drafted in line with the template resolutions publishd by the UK Pre-Emption Group in November 2022.

It should be noted that the articles of association of the Company empower the directors to allot equity securities (as defined in the articles of association of the Company) wholly for cash in connection with a pre-emptive issue (as defined in the articles of association of the Company).

Resolution 19

The purpose of resolution 19, which will be proposed as a special resolution, is to put in place a new authority to enable the Company to make market purchases of up to 91,818,298 ordinary shares, being approximately 10% of the issued ordinary share capital of the Company, exclusive of treasury shares, as at 24 May 2024. The Company's exercise of this authority is subject to the stated upper and lower limits on the price payable which reflect the requirements of the UK Listing Rules and the provisions of Article 57 of the Companies (Jersey) Law 1991. The Company will only exercise the power of purchase after careful consideration and in circumstances where, in the light of market conditions prevailing at the time, it is satisfied that it is in the best interests of the Company and of its shareholders generally to do so and where there would be a resulting increase in earnings per share.

The Companies (Jersey) Law 1991 permits the Company to hold any shares purchased by it as treasury shares, as an alternative to immediately cancelling them. If the Company purchases any of its ordinary shares and holds them as treasury shares, the Company may sell these shares (or any of them) for cash, transfer these shares (or any of them) for the purposes of or pursuant to an employee share plan, cancel these shares (or any of them) or continue to hold them as treasury shares. Holding such shares as treasury shares allows the Company to reissue them quickly and cost effectively and provides additional flexibility in managing the Company's capital base. No dividends will be paid on, and no voting rights will be exercised in respect of, shares held as treasury shares.

As at 24 May 2024, the Company held 54,008,546 ordinary shares in treasury. If any ordinary shares are purchased by the Company, the directors intend to decide whether to cancel shares purchased pursuant to this authority or hold them as treasury shares based on the interests of the Company and its shareholders as a whole at the relevant time.

If granted, this authority will expire on the earlier of 16 October 2025 and the conclusion of the Annual General Meeting to be held in 2025.

As at 24 May 2024, there were options outstanding over 15,813,595 ordinary shares, representing 1.72% of the issued ordinary share capital of the Company, exclusive of treasury shares, at that date. If the full authority being sought under resolution 19 was utilised, so reducing the issued ordinary share capital by an equivalent amount, the figure of 15,813,595 would represent 1.91% of the issued ordinary share capital of the Company, exclusive of treasury shares, at that date.
