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.

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.

Considering this recommendation, and acknowledging the EHQHȴWVRIUHIUHVKLQJ%RDUGPHPEHUVKLSSHULRGLFDOO\WKH Nomination Committee concluded:

• Board performance review outcomes: The recent external review highlighted strong satisfaction with John's leadership and independence, and his deep understanding of Informa's operations and strategy. His continuing and substantial time commitment to Informa was also noted.
• Global experience: John's expertise in international EXVLQHVVFURVVERUGHUȴQDQFHDQGJOREDOPDUNHWV particularly in the Middle East, remains invaluable as we continue to develop our partnership with DWTC and strengthen our Tahaluf partnership in Saudi Arabia.
• Board stability: Following the appointment of new Directors in 2024 and the relocation of key executives in 2025, leadership continuity is critical.

As a result, the Committee unanimously agreed that extending the Chair's tenure was in the best interests of the company and its stakeholders. Although the Nomination Committee KDVEHJXQDSURFHVVWRȴQGKLVVXFFHVVRUZLWKWKHDVVLVWDQFH of Russell Reynolds, the Chair has agreed to seek re-election at the AGM in 2026 – but not in 2027 – in order to ensure that there is a smooth handover with his successor.

Resolution 11: 2025 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 auditor as well as the ȴQDQFLDOVWDWHPHQWVIRUWKH\HDUHQGHG'HFHPEHU The Annual Report can be found at informa.com

Resolution 12: Directors' Remuneration Report

This resolution seeks shareholder approval for the Directors' Remuneration Report (DRR) for the year ended 31 December 2025, set out on pages 109 to 123 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 2026.

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 133 of the Annual Report.

Resolution 13: Final Dividend

The Companies Act requires that independent auditors are appointed at each general meeting at which accounts are SUHVHQWHGWRVKDUHKROGHUV7KHDXGLWRUVZLOOXVXDOO\KROGRɝFH from the conclusion of that meeting until the next general meeting at which accounts are presented.

Committee on the Board's behalf. Details of all fees paid to the auditors for the year ended 31 December 2025 are set out in Note 6 of the Annual Report.

5HVROXWLRQ\$XWKRULW\WRPDNHSROLWLFDO donations

The authority being proposed in this resolution 16 is a renewal of the authority granted at the 2025 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 2026, nor was it used during 2025.

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 PRQWKSHULRGDQGIRUDQ\SROLWLFDOH[SHQGLWXUHVXEMHFWWR limited exceptions.

These activities are not GHVLJQHGWRVXSSRUWDQ\SROLWLFDOSDUW\QRUWRLQȵXHQFHSXEOLF 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 2027.

Resolution 17: 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 17 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 17 will, if passed, authorise the Directors to allot (or grant rights over) shares (i) up to a nominal amount of £423,664 being one third of the issued ordinary share capital of the company on 22 April 2026 (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 £423,664, 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 17 September EXWWKHFRPSDQ\PD\PDNHRHUVDQGHQWHULQWR 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 FHUWDLQULJKWVRYHUVKDUHV?XQGHUDQ\VXFKRHURUDJUHHPHQW 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 WKHȵH[LELOLW\WKDWWKLVDXWKRULW\SURYLGHVDQGWKHUHIRUHWKH 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 18 and 19: Disapplication of pre-emption rights

Under section 561(1) of the Companies Act, if the Directors wish to exercise the authority given under resolution 17 to issue shares for cash (other than in relation to an employee share VFKHPH?WKH\PXVWȴUVWRHUWKRVHVKDUHVWRWKHFRPSDQ\ȇV existing shareholders in proportion to their holdings unless VKDUHKROGHUVKDYHJLYHQVSHFLȴFDXWKRULW\WRZDLYHWKHLU statutory pre-emption rights.)

Resolutions 18 and 19 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 RQO\LQFRQQHFWLRQZLWKWKHȴQDQFLQJRUUHȴQDQFLQJLIWKH authority is to be used within 12 months after the original WUDQVDFWLRQ?RIDQDFTXLVLWLRQRUVSHFLȴHGFDSLWDOLQYHVWPHQW 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 WKH'LUHFWRUVWRDOORWVKDUHVIRUFDVKZLWKRXWDSULRURHULQJ to existing shareholders. Resolutions 18 and 19 are seeking to renew these authorities.

Resolution 18 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 £127,099, being approximately 10% of the company's issued ordinary share capital at the Latest Practicable Date.

Resolution 19 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 £127,099, again approximately 10% of issued ordinary share capital as at the Latest Practicable Date.

The Directors will only use the power conferred by resolution LQFRQQHFWLRQZLWKDQDFTXLVLWLRQRUDVSHFLȴHGFDSLWDO 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 18 and 19 will expire at the earlier of the end of the company's next AGM or 17 September 2027.

Explanatory Notes on the Resolutions

Resolution 20: 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 276,941,795 ordinary shares at an aggregate purchase price of £1.963 billion (excluding transaction costs).

The resolution would allow the Directors to buy back up to 127,099,000 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 17 September 2027.

Resolution 21: Authority to call general meetings on 14 days' notice

This resolution would renew the authority given at the 2025 AGM and allow the company to call general meetings (other than annual general meetings) on 14 clear days' notice.
