Impax Asset Management Group Plc

Launch of £10m share buyback programme

Impax Asset Management Group plc ("Impax" or the "Company") announces it will commence a share buyback programme, starting today, of its ordinary shares of 1p each (the "Ordinary Shares") for up to a maximum aggregate consideration of £10 million (the "Programme").

The purpose of the share buyback is to return additional capital to shareholders as a result of the update on the capital management priorities announced in the Company's interim results which were announced today.

The Programme will be effected under the authority granted by shareholders at the Company's AGM on 5 March 2025 to undertake on-market share buy-backs of up to 13,259,655 Ordinary Shares.  

The Group is entering into an arrangement with Peel Hunt LLP ("Peel Hunt") to conduct the Programme, which will commence immediately and will end no later than 31 December 2025. However, there is no guarantee that the Programme will be implemented in full.

Any purchase of Ordinary Shares under the Programme will be carried out on the London Stock Exchange and/or other trading venues. Details of any and all purchases made under the Programme will be provided via RNS announcements by no later than 7.30 a.m. on the business day following the calendar day on which the purchase occurred. Any Ordinary Shares purchased under the Programme will be cancelled.

Due to the limited liquidity in the Ordinary Shares, a buy-back of Ordinary Shares on any trading day may represent a significant proportion of the daily trading volume in the Ordinary Shares and may exceed the 25% of the average daily trading volume specified in the provisions of the UK Market Abuse Regulation dealing with buyback programmes and accordingly the Company will not benefit from the exemption contained in Article 5(1) of that regulation.
