Share Fraud - Protecting Your Investment

We are aware that, from time to time, some shareholders are approached by individuals claiming to be acting on behalf of Informa PLC or an Informa subsidiary.

Shareholders are strongly advised to be highly cautious about any unsolicited phone calls or correspondence about investment matters, whether they claim to be associated with Informa PLC, an Informa company, an Informa Director or any other company or scheme.

Neither Informa PLC nor any Director of an Informa company will ever offer investment advice or make unsolicited calls or send unsolicited emails or letters about buying or selling shares.

Fraudsters can be very persistent and extremely persuasive and often have websites that support their activities and claim to be related to the websites of genuine companies. If it sounds too good to be true, it probably is.

What to do

• Treat any unsolicited call with an offer to buy or sell shares with extreme caution – the safest thing to do is hang-up.
• Do not give out or confirm any personal information.
• If you have a conversation with someone, try to make a note of their name and that of their organisation – name, telephone number and web address if possible.
• Do not hand over any money without first checking that the organisation is genuine and authorised by Financial Conduct Authority (FCA) at fca.org.uk/register.
• The FCA keeps a warning list of companies on its ScamSmart website fca.org.uk/scamsmart.

Report the issue

If you think you have been targeted, you should report the matter to the FCA as soon as possible via their online form at fca.org.uk/consumers/scams or by calling the consumer helpline on 0800 111 6768 from the UK or +44 20 7066 1000 from outside the UK.

You can also report any suspicious contact received via the Action Fraud website at actionfraud.police.uk or by calling 0300 123 2040.

If you receive telephone calls, emails or letters purporting to be from Informa, or companies endorsed by Informa, and you are unsure if they are legitimate, please contact our Computershare shareholder helpline on 0370 707 1679 or email our Investor Relations team at investorrelations@informa.com.

Catherine became a member of the Remuneration Committee in March 2025. Both will stand for election by shareholders at the AGM. All other Directors will stand for re-election and biographies for each Board member can be found on pages 7 and 8.

SPECIAL RESOLUTIONS

Resolution 19: General power to disapply pre-emption rights

That, if Resolution 18 is passed, the Directors be authorised, in substitution for all existing powers and pursuant to section 570 of the Companies Act, to allot equity securities (as defined in section 560(1) of the Companies Act) for cash under the authority granted by Resolution 18 and/or to sell treasury shares for cash as if section 561 of the Companies Act did not apply to any such allotment or sale, such authority to be limited to:

This authority will apply until the earlier of the end of the company's next AGM or close of business on 18 September 2026 (unless previously renewed, varied or revoked by the company in a general meeting), but, in each case, during this period 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) and the Directors may allot equity securities (and sell treasury shares) under any such offer or agreement as if this authority had not ended.

Explanatory Notes on the Resolutions

The explanatory notes that follow form part of the Notice and provide important information regarding the items of business to be considered at the AGM.

Resolutions 1 to 18 (inclusive) are proposed as ordinary resolutions. This means that for each of these resolutions to be passed, more than half of the votes cast must be in favour of the resolution. Resolutions 19 to 22 (inclusive) are proposed as special resolutions. This means that for each of these resolutions to be passed, at least 75% of the votes cast must be in favour of the resolution.

Resolutions 1 to 11: Election of Directors

As is usual, and in line with the 2018 UK Corporate Governance Code 2018 (the Code), Maria Kyriacou and Catherine Levene will offer themselves for election and all other Directors will offer themselves for re-election at the AGM.

On behalf of the Board, the Chair confirms that each Director standing for re-election remains committed to their role and continues to be an effective and valuable member of the Board. The Board is also content that each Non-Executive Director is independent and there are no relationships or circumstances likely to affect their character or judgement. The Board is satisfied that each of the Directors has the appropriate balance of skills, experience, independence and knowledge of the company to enable them to discharge the duties and responsibilities of a director effectively.

Detailed biographies for each Director can be found on pages 7 and 8 of this document.

Resolution 12: 2024 Annual Report

The Directors present the Annual Report to shareholders at the AGM. The Annual Report contains the reports of the Directors (including the Strategic Report) and auditors as well as the financial statements for the year ended 31 December 2024. The Annual Report can be found at informa.com

Resolution 13: Directors' Remuneration Report

This resolution seeks shareholder approval for the Directors' Remuneration Report (DRR) for the year ended 31 December 2024, set out on pages 115 to 132 of the Annual Report.

The DRR gives details on how the company's remuneration policy has been implemented during the year and the payments and share awards, if any, made to the Directors. The DRR also gives details of how the company intends to apply the remuneration policy during 2025.

The vote on this resolution is advisory and the Directors' entitlement to remuneration is not conditional on it being passed.

The company's auditors, PwC, have audited those sections of the DRR that are required to be audited and their report relating to the DRR can be found on page 143 of the Annual Report.

Resolution 14: Final Dividend

This resolution seeks shareholder approval to pay a final dividend of 13.6 pence per share for the year ended 31 December 2024. The dividend, if approved, will be paid on 11 July 2025 to shareholders on the register at 6.00pm BST on 30 May 2025. The ex-dividend date is 29 May 2025.

We encourage shareholders to elect to receive dividends paid directly to their banks to avoid the delays, risk and inconvenience associated with cheques. Shareholders with UK bank accounts can register their bank details at investorcentre.co.uk. Overseas holders can register for the Global Payment Service allowing the dividend to be paid in the local currency at investorcentre.co.uk.

If you have already registered to receive payment directly to your bank, then please check that your payment details are up to date by visiting investorcentre.co.uk and either logging into your account or registering.

Resolutions 15 and 16: Re-Appointment of auditors and auditors' remuneration

The Companies Act requires that independent auditors are appointed at each general meeting at which accounts are presented to shareholders. The auditors will usually hold office from the conclusion of that meeting until the next general meeting at which accounts are presented.

PwC have indicated their willingness to continue in office as auditors of the company. Following the recommendation of the Audit Committee, resolution 15 therefore proposes that PwC be reappointed as the Company's auditors.

Resolution 16 seeks authorisation from shareholders for the Directors to agree the auditors' fees. In practice, and in line with the Code, audit fees are considered and approved by the Audit Committee on the Board's behalf. Details of all fees paid to the auditors for the year ended 31 December 2024 are set out in Note 6 of the Annual Report.

Resolution 17: Authority to make political donations

The authority being proposed in this resolution 17 is a renewal of the authority granted at the 2024 AGM.

The company does not make any donations to political parties or incur political expenditure as those terms are normally understood, and the Directors have no intention of using this authority for that purpose during 2025, nor was it used during 2024.

The Companies Act requires companies to obtain shareholder authority for donations to registered political parties and other political organisations totalling more than £5,000 in any 12-month period and for any political expenditure, subject to limited exceptions.

The definition of political donations used in the Companies Act is very wide and, as a result, could inadvertently catch legitimate activities such as policy review, law reform and the representation of the business community and special interest groups which the company may wish to support. These activities are not designed to support any political party nor to influence public support for a particular party.

To avoid any inadvertent infringement of the Companies Act, shareholders are asked to renew the authority which will apply until the end of the AGM in 2026.

Resolution 18: Authority to allot shares

Under section 551 the Companies Act, the Directors are only authorised to allot shares (or grant certain rights over shares) if they have been authorised to do so by shareholders. Resolution 18 would renew the authority previously given to the Directors at last year's AGM.

The Investment Association (IA) share capital management guidelines on directors' authority to allot shares state that its members will permit, and treat as routine, resolutions seeking authority to allot shares representing up to two thirds of the Company's issued share capital. The guidelines provide that any routine authority to allot shares representing more than one third of the Company's issued share capital should only be used to allot shares pursuant to a fully pre-emptive rights issue.

Resolution 18 will, if passed, authorise the Directors to allot (or grant rights over) shares (i) up to a nominal amount of £439,523 being one third of the issued ordinary share capital of the company on 22 April 2025 (being the latest practicable date prior to the publication of this Notice (the Latest Practicable Date)) and (ii) in connection, up to a further aggregate nominal value of £439,523, again being one-third of the issued ordinary share capital on the Latest Practicable Date, in connection with a fully pre-emptive rights issue only.

The authority will apply until the earlier of the end of the company's next AGM or close of business on 18 September 2026, but the company may make offers and enter into agreements which would, or might, require shares to be allotted (or certain rights granted over shares) after the authority expires and the Directors may allot shares (or grant certain rights over shares) under any such offer or agreement as if the authority had not expired.

The Directors do not have any present intention to exercise this authority, however they consider it appropriate to maintain the flexibility that this authority provides and therefore the Directors are again seeking to renew this authority. If the authority is exercised in the future, the Directors intend to follow best practice as recommended by the IA. As previously stated, it is anticipated that the Directors will seek to renew this authority at each AGM.

The company does not currently hold any shares in treasury.

Resolutions 19 and 20: Disapplication of pre-emption rights

Under section 561(1) of the Companies Act, if the Directors wish to exercise the authority given under resolution 18 to issue shares for cash (other than in relation to an employee share scheme), they must first offer those shares to the company's existing shareholders in proportion to their holdings unless shareholders have given specific authority to waive their statutory pre-emption rights.) There may be occasions, when the Directors need the flexibility to issue shares for cash to finance business opportunities without first offering them to existing shareholders. Resolutions 19 and 20 would allow the Directors to disapply the strict statutory pre-emption provisions in these circumstances.

The PEG Statement of Principles supports companies seeking authority to disapply the pre-emption provisions when issuing shares for cash in relation to:

• (i) 10% of issued ordinary share capital for use on an unrestricted basis (a general disapplication); and
• (ii) an additional 10% of issued ordinary share capital to be used only in connection with the financing (or refinancing, if the authority is to be used within 12 months after the original transaction) of an acquisition or specified capital investment which is announced contemporaneously with the allotment, or which has taken place in the preceding 12 month period and is disclosed in the announcement of the allotment.

At last year's AGM, shareholders passed resolutions authorising the Directors to allot shares for cash without a prior offering to existing shareholders. Resolutions 19 and 20 are seeking to renew these authorities.

Resolution 19 will permit the Directors to allot ordinary shares for cash (or sell treasury shares) on a non-pre-emptive basis up to a maximum nominal amount of £131,857, being approximately 10% of the company's issued ordinary share capital at the Latest Practicable Date.

Resolution 20 will permit the Directors to additionally allot ordinary shares for cash (or sell treasury shares) on a non-preemptive basis up to a further maximum nominal amount of £131,857, again approximately 10% of issued ordinary share capital as at the Latest Practicable Date.

The Directors will only use the power conferred by resolution 20 in connection with an acquisition or a specified capital investment which is announced contemporaneously with the issue, or which has taken place in the preceding twelve-month period and disclosed in the announcement of the issue.

The Directors have no present intention to exercise the authorities conferred by these resolutions.

The authorities granted by resolutions 19 and 20 will expire at the earlier of the end of the company's next AGM or 18 September 2026.

Resolution 21: Authority to purchase own shares

On 14 February 2022, the company commenced a share buyback programme of its ordinary shares of 0.1 pence each. As at the Latest Practicable Date, the company has repurchased and cancelled over 229 million ordinary shares at an aggregate purchase price of £1.57 billion (excluding transaction costs).

Resolution 21 will allow the Board to retain forward flexibility by renewing the authority granted at last year's AGM. The resolution would allow the Directors to buy back up to 131,857,000 of its issued ordinary shares, equal to 10% of the company's issued ordinary shares on the Latest Practicable Date and sets out the lowest and highest prices that can be paid for the shares, exclusive of expenses.

Any shares which are bought back under this authority may either be cancelled or held in treasury. No dividends are paid on shares whilst held in treasury and no voting rights attach to them. The company's present intention to cancel all purchased shares. However, in order to respond properly to the company's capital requirements and prevailing market conditions, the Directors will reassess whether to cancel the purchased shares or hold them in treasury at the time of any and each actual purchase.

The buyback authority will automatically expire at the earlier of the end of the company's next AGM or close of business on 18 September 2026.

Explanatory Notes on the Resolutions

Resolution 22: Authority to call general meetings on 14 days' notice

This resolution would renew the authority given at the 2024 AGM and allow the company to call general meetings (other than annual general meetings) on 14 clear days' notice.

The Companies Act requires listed companies to call general meetings on at least 21 clear days' notice unless shareholders approve a shorter notice period, which cannot be less than 14 clear days - annual general meetings must always be held on at least 21 clear days' notice.

If passed, the authority granted by this resolution will be effective until the company's next AGM when a similar resolution will be proposed.

The flexibility offered by this resolution will only be used where, taking into account the circumstances, the Directors consider it is merited by the business of the general meeting and is thought to be to the advantage of the company and shareholders as a whole.

The company offers the facility for all shareholders to vote by electronic means at any general meeting. The company also provides the ability to appoint proxies electronically through CREST and retail shareholders can vote online via investorcentre.co.uk/eproxy.

Meeting information

The following notes explain your general rights as a shareholder and your rights to attend and vote at the 2025 AGM or to appoint someone else to vote on your behalf.

Entitlement to attend and vote

• 1. Only shareholders named on the company's register of members at 6.00pm BST on Tuesday 17 June 2025 (or, in the event of any adjournment, 6.00pm BST on the day which is two days before the adjourned meeting excluding any non-working days) are entitled to attend and vote, whether in person, electronically or by proxy, at the AGM in respect of the number of shares registered in their name at that time. Changes to the register of members after the relevant deadline will be disregarded in determining the rights of any person to attend and vote.
• 1. Any shareholder attending the meeting in person, electronically or by proxy has the right to ask questions. The company must provide an answer to any question relating to the business being dealt with at the meeting, but no such answer need be given if
  2. (i) to do so would interfere unduly with the preparation for the meeting or involve the disclosure of confidential information,
  3. (ii) the answer has already been given on a website in the form of an answer to a question, or
  4. (iii) it is undesirable in the interests of the company or the good order of the meeting that the question be answered.

Shareholders may also submit questions in advance of the AGM by emailing AGM@informa.com. Please include your full name and shareholder reference number. We will consider all questions received and, if appropriate and relating to the business of the AGM, give an answer at the AGM, provide a written response or put responses on our website.

Appointment of proxy

1. Shareholders are entitled to appoint a proxy to exercise all or any of their rights to attend the AGM and to speak and vote on their behalf. A proxy does not need to be a member of the company.

A shareholder may appoint more than one proxy in relation to the AGM provided that each proxy is appointed to exercise the rights attached to a different share or shares held by that shareholder. Any shareholder appointing more than one proxy should indicate the number of shares for which each proxy is authorised to act on their behalf.

The proxy form that accompanies this document must be used to appoint a proxy. Please read the instructions on the proxy form.

If you did not receive a proxy form and believe that you should have received one, or if you require additional forms, please call Computershare on 0370 707 1679 between 8.30am and 5.30pm, Monday to Friday.

You can only appoint a proxy using the procedures set out in the proxy instructions.

To be valid, proxy forms, and the original (or a certified true copy) of any power of attorney or other authority under which the proxy form is signed, must be received at the offices of the Registrar, Computershare Investor Services PLC, The Pavilions, Bridgewater Road, Bristol BL99 6ZY, by 09.00am BST on Tuesday 17 June 2025. A reply-paid envelope has been enclosed for the return of your proxy form.

Shareholders may also register the appointment of a proxy electronically at investorcentre.co.uk/eproxy. You will need the Control Number, Shareholder Reference Number and PIN which are set out on your proxy form or the electronic broadcast you received from us.

Electronic proxy appointments must also be received by 09.00am BST on Tuesday 17 June 2025. Proxies received after that date, or sent to any other address, will not be valid. Any electronic communication found to contain a computer virus will not be accepted.

In the case of joint holders, where more than one of the joint holders appoints a proxy, only the appointment submitted by the most senior holder will be accepted. Seniority is determined by the order in which the names of the joint holders appear in the company's register of members with the first-named being the most senior.

Shareholders may not use any electronic address provided either in this Notice or any related documents (including the proxy form) to communicate with the company for any purposes other than those expressly stated. Shareholders may not use any telephone number set out in this Notice for the purpose of lodging instructions for the 2025 AGM. Similarly, the company's website may not be used to send documents or instructions for the AGM.

Accessing electronic voting during the meeting

1. Should you wish to attend the AGM and vote electronically at the meeting using the technology provided by Lumi, please refer to the detailed information on page 12 of this document.

If your investment is not held in your name on the register of members (i.e. it is held in a broker account or by a custodian), it will be necessary for you to be appointed as a proxy or corporate representative to attend, ask questions and vote at the AGM. You should therefore follow the procedures set out in this Notice to be appointed as a proxy or corporate representative.

Once you have been validly appointed as a proxy or corporate representative, you will need to contact the Company's registrar, Computershare, on 0370 707 1679 before 9.00 a.m. BST on Wednesday 18 June 2025 for your unique Shareholder Reference Number (SRN) and PIN.

Should you wish to appoint someone other than the Chair of the meeting as your proxy or corporate representative to vote electronically at the AGM, you will need to follow the steps set out above.

Meeting information

CREST

1. 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 on 19 June 2025 and any adjournment(s) thereof by using the procedures described in the CREST Manual. 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.

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 the specification of Euroclear UK & International Limited (Euroclear) and must contain the information required for such instructions, as described in the CREST Manual (available via 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 3RA50) by 09.00am BST on Tuesday 17 June 2025.

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 the issuer's agent is able to retrieve the message by enquiry to CREST in the manner prescribed by CREST. After this time any change of instructions to proxies appointed through CREST should be communicated to the appointee through other means.

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 his 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 regard, CREST members and, where applicable, their CREST sponsors or voting service providers are referred 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 (as amended).

Proxymity voting

1. If you are an institutional investor, you may also be able to appoint a proxy electronically via the Proxymity platform. For further information regarding Proxymity, please go to proxymity.io. Before using Proxymity you will need to have agreed to their associated terms and conditions. It is important that you read these carefully as they govern the electronic appointment of your proxy.

To be valid, your instruction must be received by 09.00am BST on Tuesday 17 June 2025.

Corporate Representatives

1. Any corporation which is a member of the company can appoint one or more corporate representatives to exercise its powers as long as they do not do so in relation to the same shares.

Nominated Persons

1. Any person who receives this Notice as a person nominated under section 146 of the Companies Act to enjoy information rights (a Nominated Person) may, under an agreement between them and the member by whom they were 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, they may, under any such agreement, have a right to give instructions to the member as to the exercise of voting rights.

The statement of the rights of shareholders in relation to the appointment of proxies in Note 3 above does not apply to Nominated Persons. The rights described in those paragraphs can only be exercised by the company's registered shareholders.

Nominated Persons should contact the registered holder of their shares on matters relating to their investments in the company.

Total voting rights

1. As at 22 April 2025 (being the Latest Practicable Date prior to the publication of this Notice) the company's issued share capital consisted of 1,318,571,627 ordinary shares carrying one vote each. The company does not hold any shares in treasury.

Requests under section 527 of the Companies Act

• 1. Under section 527 of the Companies Act, shareholders meeting the threshold requirements set out in that section have the right to require the company to publish on a website a statement setting out any matter relating to:
  2. (i) the audit of the company's accounts (including the auditors' report and the conduct of the audit) that are to be laid before the AGM; or
  3. (ii) any circumstance connected with the auditors 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 Companies Act.

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. Where the company is required to place a statement on a website under section 527 of the Companies 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.
