LETTER TO SHAREHOLDERS

Dear shareholders,

Auto Trader Group plc (the 'Company') will be holding its 2025 Annual General Meeting ('AGM') at 11:00am on Thursday 18 September 2025, at the Company's registered office: 4th Floor, 1 Tony Wilson Place, Manchester M15 4FN, United Kingdom.

The AGM is an important day in our calendar, and it is the Board of the Company's (the 'Board') opportunity to listen and respond to your questions.

We strongly encourage all shareholders to cast their votes by proxy, and recommend that you appoint the chair of the meeting as your proxy in order for your vote to be counted at the AGM. We encourage you to send any questions in respect of AGM business to ir@autotrader.co.uk beforehand.

Voting

At the meeting itself, voting on all the proposed resolutions will be conducted on a poll rather than a show of hands, in line with recommended best practice. Voting by poll is more transparent and equitable because it includes the votes of all shareholders who have cast their vote by proxy, rather than just the votes of shareholders who attend the AGM.

Shareholders of the Company will be asked to consider and, if thought fit, approve resolutions in respect of the matters set out on pages 2 and 3. The results will be published on our website plc.autotrader.co.uk/investors and they will also be released to the London Stock Exchange.

Website

Our corporate website plc.autotrader.co.uk/investors provides more information about the Company including:

• a copy of our full Annual Report and Financial Statements; and
• all the latest Auto Trader news and regulatory announcements.

Explanatory notes

An explanation of each of the resolutions is set out on pages 4 and 5.

Following the close of the AGM, our Corporate Responsibility Committee Chair, Jeni Mundy, will step down from the Board having served a nine year term and Sigga Sigurdardottir will step down from the Board having served a six year term. In accordance with the UK Corporate Governance Code, all of the directors of the Company (the 'Directors') save for Megan Quinn and Adam Jay will offer themselves for re-election by shareholders.

Biographies of the Board can be found on pages 6 and 7 of this notice. Following the outcome of the internal Board performance review process, the Nomination Committee concluded that each Director offering themselves for election or re-election makes an effective and valuable contribution to the Board and to the Committees on which they sit and demonstrates commitment to the role, including commitment of time for Board and Committee meetings and any other required duties.

Admission on the day

If possible, please arrive by 10:45am to allow sufficient time for registration and security clearance. Please bring your attendance document with you. This will be a copy of the email you will have received.

Action to be taken

Shareholders are able to vote online at www.shareview.co.uk by creating an online portfolio using their Shareholder Reference Number printed on the Proxy. Those holders who are registered for electronic communications will be sent an email incorporating a link to the online voting site (see below).

Electronic Proxy Appointment ('EPA') is available for the AGM. EPA enables shareholders to lodge their proxy appointment by electronic means via a website provided by the Company's registrar, Equiniti Limited (the 'Registrar'), at www.shareview.co.uk.

CREST members may use the CREST electronic proxy appointment service to submit their proxy appointment in respect of the AGM. Our CREST Issuer Agent ID is RA19.

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.

Further information regarding the appointment of proxies and voting is set out on pages 8 and 9.

Please note that all proxy votes and appointments, whether postal or electronic, must be received by the Registrar no later than 11:00am on Tuesday 16 September 2025.

Recommendation

The Board believes that the adoption of resolutions 1 to 19 will promote the success of the Company and is in the best interests of the Company and its shareholders as a whole. The Board unanimously recommends that all shareholders should vote in favour of all the resolutions to be proposed at the AGM, each of which is set out in the Notice of Meeting. Each of the Directors of the Company intends to vote in favour of all resolutions in respect of their own beneficial holdings.

Yours sincerely,

Matt Davies

Chair For and on behalf of Auto Trader Group plc 27 June 2025

EXPL ANATORY NOTES

Additional information about the proposed resolutions

This section contains an explanation of each of the resolutions to be put to the AGM. Resolutions 1 to 15 (inclusive) are ordinary resolutions, meaning each resolution requires more than half the votes cast to be in favour of the resolution to be passed. Resolutions 16 to 19 (inclusive) are special resolutions, meaning each resolution requires at least 75% of the votes cast to be in favour of the resolution to be passed.

Resolution 1: To receive the Annual Report and Financial Statements

Shareholders are invited to receive the audited financial statements for the financial year ended 31 March 2025 together with the Directors', auditors' and strategic reports on those financial statements, which are contained in the Annual Report and Financial Statements.

Resolution 2: Approval of the Directors' remuneration report

The Directors' remuneration report is set out in full in the Annual Report and Financial Statements on pages 95 to 108.

In accordance with the provisions of the 2006 Act and the Large and Medium-Sized Companies and Groups (Accounts and Reports) Regulations 2008, the Directors' remuneration report in the Annual Report and Financial Statements contains:

• the annual statement by Geeta Gopalan, Chair of the Company's Remuneration Committee; and
• the annual implementation report on remuneration, which sets out the payments made in the financial year ending 31 March 2025.

The report also contains a summary of the Directors' Remuneration Policy in relation to future payments to the Directors and former Directors, which was approved by shareholders at the AGM on 19September 2024.

The annual statement from the Chair of the Company's Remuneration Committee, set out on pages 95 to 96 of the Annual Report and Financial Statements, summarises, for the financial year ended 31 March 2025, the major decisions taken on Directors' remuneration, any substantial changes relating to Directors' remuneration made during the financial year and the context in which those changes occurred and decisions have been taken.

The annual implementation report on remuneration, set out on pages 102 to 108 of the Annual Report and Financial Statements, provides details of the remuneration paid to Directors in respect of the financial year ended 31 March 2025, including base salary, taxable benefits, pension related benefits, any other items in the nature of remuneration and any sum(s) recovered or withheld during the financial year in respect of amounts paid in earlier periods.

Resolution 2 is to approve the Directors' remuneration report. This is an advisory resolution and does not affect the future remuneration paid to any Director, or any remuneration already paid to any Director.

Resolution 3: Declaration of final dividend

The Company paid an interim dividend of 3.5 pence per ordinary share in January 2025. The Board recommends a final dividend of 7.1 pence per ordinary share bringing the total dividend for the year o 10.6 pence per ordinary share. Subject to approval by shareholders, the final dividend will be paid on 26 September 2025 to shareholders who appeared on the register of members at the close of business on 29 August 2025.

Resolutions 4 to 12: Election and re-election of Directors

In accordance with the Code and the Company's Articles, each new Director appointed to the Board should be subject to election by shareholders at the first AGM following their appointment, and all Directors should be subject to annual re-election by shareholders. Biographies of the Board can be found on pages 6 and 7 of this notice. The Chair confirms that, in respect of all Directors offering themselves for election or re-election at the AGM, their performance continues to be effective and they demonstrate commitment to the role.

The Directors' biographies include information in support of the Board's view that each Director's contribution is, and continues to be, important to the Company's long-term sustainable success. The Board recommends the election of the Directors as set out in resolutions 4 to 12.

Further details of the activities of the Nomination Committee can be found on pages 84 to 86 of the Annual Report and Financial Statements.

Resolutions 13 and 14: Appointment of auditors and auditor remuneration

Auditors are required to be appointed, or re-appointed, at each annual general meeting at which accounts are presented.

Resolution 13 proposes that KPMG LLP are re-appointed as auditors of the Company and that they hold office from the conclusion of this meeting until the conclusion of the next general meeting at which accounts are laid before the Company.

Resolution 14 authorises the Board, in accordance with standard practice, to agree the remuneration of the auditors. In practice, the Audit Committee will consider and approve the remuneration of the auditors on behalf of the Board.

Resolution 15: Authority to allot shares

Resolution 15 seeks the approval of shareholders, pursuant to the provisions of section 551 of the 2006 Act, to confer on the Board the authority to allot shares in the Company, or to grant Rights, for a period ending at the close of the Company's next annual general meeting or, if earlier, the close of business on 17 December 2026. The Board's existing authority expires at the close of the forthcoming AGM.

If passed, the renewed authority would permit the allotment of relevant securities with an aggregate nominal amount of £2,911,735, representing 33.33% of the issued share capital of the Company (excluding treasury shares) as at 20 June 2025 (being the last practicable date prior to publication of this notice), save in connection with a pre-emptive offer to existing shareholders in which case the authority would permit the allotment of ordinary shares with an aggregate nominal amount of £5,824,344 representing 66.67% of the issued share capital of the Company (excluding treasury shares) as at 20 June 2025 (being the last practicable date prior to publication of this notice), such amount to be reduced by the aggregate nominal amount issued under paragraph 15(a)(i) of this resolution. This is in accordance with the latest guidelines published by the Investment Association.

The Board has no current intention of exercising this authority. However, if the Board does exercise this authority, the Board intends to follow best practice as regards its use (as recommended by the Investment Association).

As at 20 June 2025 (being the last practicable date prior to publication of this notice), 4,550,279 ordinary shares were held by the Company in treasury which represented approximately 0.52% of the issued share capital of the Company (excluding treasury shares). Resolutions 16 and 17: Partial disapplication of pre-emption rights Resolutions 16 and 17 seek the approval of shareholders, pursuant to the provisions of sections 570 and 573 of the 2006 Act, to waive the statutory pre-emption rights applicable to the allotment of equity securities for cash.

The power under resolution 16 is limited to allotments: (i) for cash in connection with pre-emptive offers, subject to any arrangements that the Directors consider appropriate to deal with fractions and overseas requirements and (ii) otherwise for cash up to a maximum nominal value of £436,804 representing 5% of the issued share capital of the Company (excluding treasury shares) as at 20 June 2025 (being the last practicable date prior to publication of this notice).

If approved, the section 570 and 573 powers shall apply until the end of the next annual general meeting of the Company after the date on which these resolutions are passed or, if earlier, at the close of business on 17 December 2026.

Resolution 17 would give the Directors authority to allot a further 5% of the issued ordinary share capital of the Company (excluding treasury shares) as at 20 June 2025 (being the last practicable date prior to publication of this notice) for the purposes of financing a transaction which the Directors determine to be an acquisition or other capital investment contemplated by the Pre-Emption Group's Statement of Principles issued in November 2022 (the 'Principles').

The disapplication authorities under resolutions 16 and 17 are in line with the guidance set out in the Principles. The Principles allow a board to allot shares for cash otherwise than in connection with a pre-emptive offer (i) up to 10% of a company's issued share capital for use on an unrestricted basis and (ii) up to a further 10% of a company's issued share capital for use in connection with an acquisition or specified capital investment announced either contemporaneously with the issue or which has taken place in the preceding 12 month period and is disclosed in the announcement of the issue.

The Directors confirm that they will follow the shareholder protections in section 2B of the Pre-Emption Group's 2022 Statement of Principles. However, the Board has no current intention to exercise these authorities.

Resolution 18: Authority to purchase own shares

Share buybacks are a way of returning cash to shareholders. Shareholders are asked at each annual general meeting for authority to carry out share buybacks in order that the Company may do so when the Board believes it is in the best interests of shareholders.

Shares that are purchased by the Company must either be cancelled or held in treasury. Treasury shares may be resold for cash or used to satisfy share options and share awards under the Company's share incentive schemes but all rights attaching to them, including voting rights and any right to receive dividends, are suspended while they are held in treasury. Treasury shares may also be cancelled.

As previously announced, the Company commenced a rolling programme of share buybacks on 15 June 2016, the purpose of which was to reduce its share capital.

Authority is sought in resolution 18 to purchase up to 87,360,792 ordinary shares, being 10% of the issued ordinary share capital of the Company (excluding treasury shares) as at 20 June 2025 (being the last practicable date prior to the publication of this notice). This resolution renews the authority granted by the shareholders at the 2024 annual general meeting and specifies the maximum number of shares that may be purchased and the minimum and maximum prices at which they may be bought. The Board will exercise the authority conferred pursuant to resolution 18 only when to do so would be in the best interests of shareholders as a whole and if the purchase could be reasonably expected to result in an increase in earnings per share.

The Company intends to continue the rolling programme of share buybacks started in June 2016, and it is the Board's current intention that any ordinary shares repurchased under this programme will be held in treasury to the extent required to satisfy existing share options and share awards under the Company's share incentive schemes, with the remainder being cancelled.

At 20 June 2025, options were outstanding to subscribe for 4,833,483 ordinary shares, representing 0.55% of the issued share capital (excluding treasury shares) at that date. If the full authority to purchase such shares (existing and sought) was exercised, they would represent 0.67% of the Company's issued share capital (excluding treasury shares). The authority sought at the AGM will expire at the conclusion of the next annual general meeting or 17 December 2026 (whichever is earlier).

Resolution 19: Notice period for general meetings

Resolution 19 seeks the approval of shareholders to reduce to 14 clear days the notice period required for a general meeting. Under the 2006 Act the notice period required for general meetings (other than annual general meetings) is 21 clear days unless shareholders approve a shorter notice period, which cannot however be less than 14 clear days. Annual general meetings must be held on at least 21 clear days' notice. It is intended that the shorter notice period would not be used as a matter of routine for general meetings but only where the flexibility is merited by the business of the meeting, the proposals are time sensitive, and it is thought to be in the best interests of the shareholders as a whole. The Company undertakes to meet the requirements for electronic voting under the Companies (Shareholders' Rights) Regulations 2009 before calling a general meeting on 14 clear days' notice. If given, the approval will be effective until the Company's next annual general meeting, at which point it is intended that a similar resolution will be proposed.

Proxies

• 2 As a holder of ordinary shares in the Company you are entitled to appoint a proxy to exercise all or any of your rights to vote at a general meeting of the Company. The notification of termination of a proxy appointment should be in writing and must be sent to Equiniti Limited, Aspect House, Spencer Road, Lancing, West Sussex, BN99 6DA or be registered electronically at www.shareview.co.uk. The revocation notice must be received no later than 11:00am on 16 September 2025. If you attempt to revoke your proxy appointment but the revocation is received after the time specified, your original proxy appointment will remain valid.
• 3 A proxy does not need to be a member of the Company but must represent you.
• 4 You may appoint more than one proxy provided each proxy is appointed to exercise rights attached to different shares. You may not appoint more than one proxy to exercise rights attached to any one ordinary share.
• 5 We strongly recommend that you appoint the chair of the meeting as your proxy in order for your vote to be counted at the AGM.
• 6 Where using a hard copy proxy form, any power of attorney or any other authority under which your form of proxy is signed (or a duly certified copy of such power or authority) must be included with your form of proxy.
• 7 You can vote either:
• (a) by logging on to www.shareview.co.uk and creating an online portfolio using your Shareholder Reference Number printed on the Proxy and following the instructions, or if you have already registered with Equiniti Limited's online portfolio service, Shareview, you can submit your form of proxy at www.shareview.co.uk; or
• (b) i n the case of CREST members, by utilising the CREST electronic proxy appointment service in accordance with the procedures set out below.
• (c) 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 please go to www.proxymity.io.

If you need help with voting online, or require a paper proxy form, please contact our Registrar, Equiniti Limited, on +44 (0)371 384 2030.

In order for a proxy appointment to be valid a proxy vote must be completed. In each case the proxy vote must be received by Equiniti Limited, Aspect House, Spencer Road, Lancing, West Sussex, BN99 6DA by 11:00 am on 16 September 2025, or in the event of an adjournment of the meeting, 11:00am on the day which is two working days before the day of such adjourned meeting.

• 8 A vote withheld is not a vote in law, which means that the vote will not be counted in the calculation of votes for or against the resolution. If no voting indication is given, your proxy will vote or abstain from voting at his or her discretion. Your proxy will vote (or abstain from voting) as he or she thinks fit in relation to any other matter which is put before the meeting.
• 9 If you submit more than one valid proxy appointment, the last appointment received before the latest time for the receipt of proxies will take precedence.

10 CREST members who wish to appoint a proxy or proxies through the CREST electronic proxy appointment service may do so for the AGM to be held at 11:00am on 18 September 2025 and any adjournment(s) thereof by using the procedures described in the CREST Manual. CREST messages must bear the ID number RA19. CREST personal members or other CREST sponsored members, and those CREST members who have appointed a voting service provider(s), should refer to the 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 message (a 'CREST Proxy Instruction') must be properly authenticated in accordance with Euroclear UK & Ireland Limited specifications and must contain the information required for such instructions, as described in the CREST Manual.

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 Equiniti Limited by 11:00am on 16 September 2025 or, in the event of an adjournment of the meeting, 11:00am on the day which is two working days before the day of such adjourned meeting.

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 Limited is able to retrieve the message by enquiry to CREST in the manner presented by CREST. After such time, any change of instructions to proxies appointed through CREST should be communicated to the appointee through other means.

CREST members and, where applicable, their CREST sponsors or Voting Service Provider should note that Euroclear UK & Ireland 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 his or her 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 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 accordance with 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 please go to www.proxymity.io. Your proxy must be lodged by 11:00am on 16 September 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.

Nominated Persons

11 (a) Any person to whom this notice is sent who is a person nominated under section 146 of the 2006 Act to enjoy information rights (a 'Nominated Person') may, under an agreement between him/her and the shareholder by whom he/she was nominated, have a right to be appointed (or to have someone else appointed) as a proxy for the AGM. If a Nominated Person has no such proxy appointment right or does not wish to exercise it, he/she may, under any such agreement, have a right to give instructions to the shareholder as to the exercise of voting rights.

(b) The statement of the rights of shareholders in relation to the appointment of proxies in paragraphs 2 to 10 above does not apply to Nominated Persons. The rights described in those paragraphs can only be exercised by ordinary shareholders of the Company.

Service of documents prohibition

12 Please note that unless otherwise specified, you may not use any electronic address, telephone numbers, or website provided in this notice or any related documents to communicate with the Company or for the purpose of serving information or documents on the Company, including the service of documents or information relating to proceedings at the Company's AGM.

Total voting rights

13 As at 20 June 2025 (being the last practicable date prior to the publication of this notice) the Company's issued share capital consists of 878,158,206 ordinary shares, carrying one vote each. 4,550,279 ordinary shares were held in treasury. Therefore, the total number of voting rights in the Company as at 20 June 2025 is 873,607,927.

Membership date

14 In accordance with Regulation 41 of the Uncertificated Securities Regulations 2001, members shall only be entitled to vote at the meeting in respect of the number of ordinary shares registered in their name on the Register of Members of the Company as at close of business on 16 September 2025 or, in the case of an adjournment of the meeting, close of business on the day which is two working days before the day of such adjourned meeting. Changes to entries on the Register of Members after close of business on the relevant date shall be disregarded in determining the rights of any person to vote at the meeting.

Members' questions

15 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.

Poll voting

16 Voting on all resolutions will be conducted by way of a poll rather than on a show of hands. This is a more transparent method of voting as members' votes are to be counted according to the number of shares held. The results will be released to the London Stock Exchange and published on the Company's corporate website: plc.autotrader.co.uk/investors.

Corporate representatives

17 Any corporation which is a member can appoint one or more corporate representatives who may exercise the same powers as the corporation could exercise if it were an individual member provided that they do not do so in relation to the same shares.

Publication of audit concerns

• 18 Under section 527 of the 2006 Act shareholders meeting the threshold requirements set out in that section have the right to require the Company to publish a statement on a website setting out any matter relating to:
  • (a) the audit of the Company's financial statements and reports (including the auditors' report and the conduct of the audit) that are to be received by the shareholders at the AGM; or

(b) any circumstance connected with an auditor of the Company ceasing to hold office since the previous meeting at which annual accounts and reports were laid in accordance with section 437 of the 2006 Act.

The Company may not require the shareholders requesting any website publication to pay its expenses in complying with section 527 or 528 of the 2006 Act. Where the Company is required to place a statement on a website under section 527 of the 2006 Act, it must forward the statement to the Company's auditors not later than the time when it makes the statement available on the website.

The business which may be dealt with at the AGM will include any statement that the Company has been required under section 527 of the 2006 Act to publish on a website.

Shareholder rights regulations

19 Under sections 338 and 338A of the 2006 Act, members meeting the threshold requirements in those sections have the right to require the Company (i) to give, to members of the Company entitled to receive notice of the meeting, notice of a resolution which may properly be moved and is intended to be moved at the meeting and/or (ii) to include in the business to be dealt with at the meeting any matter (other than a proposed resolution) which may be properly included in the business. A resolution may properly be moved, or a matter may properly be included in the business unless (a) (in the case of a resolution only) it would, if passed, be ineffective (whether by reason of inconsistency with any enactment or the Company's constitution or otherwise), (b) it is defamatory of any person, or (c) it is frivolous or vexatious. Such a request may be in hard copy form or in electronic form, must identify the resolution of which notice is to be given or the matter to be included in the business, must be authorised by the person or persons making it, must be received by the Company not later than 7 August 2025, being the date six weeks before the meeting, and (in the case of a matter to be included in the business only) must be accompanied by a statement setting out the grounds for the request.

Documents on display

20 Copies of the Directors' service agreements and letters of appointment will be available at the registered office of the Company during normal business hours from the date of this notice until the date of the AGM and at the AGM from at least 15 minutes prior to the meeting until its conclusion. Electronic copies can be made available on request by email to ir@autotrader.co.uk.

Electronic communication

21 Shareholders may at any time choose to receive all shareholder documentation in electronic form via the internet, rather than through the post, and we encourage shareholders to do this in order to reduce the negative environmental impact of printing. Shareholders who decide to register for this option will receive an email each time a statutory document is published on the internet. Shareholders who wish to receive documentation in electronic form should visit www.shareview.co.uk and complete the registration process.
