3i Infrastructure plc

Further to the announcement made on 10 May 2023 the Company advises that the Notice of AGM (the "Notice") published on the Company's website and submitted to the National Storage Mechanism contained a typographical error on page 5 of the explanatory notes to the Notice in relation to Resolution 15.

The full text of the amended announcement is set out below:

Resolution 15: For legal, regulatory and practical reasons there may be occasions when the Directors will need the flexibility to issue shares without a pre-emptive offer to existing shareholders. This resolution renews the Board's authority to allot equity securities (being Ordinary Shares or rights to subscribe for, or to convert securities into, Ordinary Shares) for cash without first offering them to existing shareholders on a pro-rata basis. The limit on the number of equity securities which may be so allotted is equity securities representing 10% of the issued ordinary share capital of the Company as at the date on which Resolution 15 is passed (this would equate to 92,235,000 Ordinary Shares as at the latest practicable date prior to the date of this document). The authority expires at close of business on the date falling 15 months after the date of passing of this resolution or the conclusion of the next annual general meeting of the Company, whichever is the earlier.

A copy of the corrected Notice is available to view on the Company's website at 2023 | General Meetings | Shareholder centre | Investors | 3i Infrastructure (3i-infrastructure.com) and will also be submitted to the National Storage Mechanism for inspection at https://data.fca.org.uk/#/nsm/nationalstoragemechanism
