Share Buyback Programme Update

Boku (AIM: BOKU), a global network of Local Payment Methods, announces that it has completed its share buyback programme of 4,000,000 common stock of $0.0001 each ("Common Stock"), details of which were announced on 17 March 2026. Over the course of the share buyback programme, 4,000,000 Common Stock were repurchased at a total cost of £6,421,738, representing c.1.36% of the Company's issued share capital (net of treasury shares) at the start of the buyback. All of the Common Stock purchased in the programme have been held in Treasury.

The Company is pleased to announce that the Board has approved an extension of the current share buyback programme, originally announced on 17 March 2026, to repurchase up to a further 4,000,000 Common Stock (the "Buyback Extension").

The Company has instructed Investec Bank plc, the Company's broker, to conduct the Buyback Extension on its behalf. The Buyback Extension will be effected within certain pre-set parameters, including that the maximum price paid per Common Stock shall be 105 per cent. of the trailing five day average mid-market price, and in accordance with authority granted by the Company's Board to hold up to 5% of the Common Stock in Treasury. (the "Authority").

The Buyback Extension will be effective from 1 June 2026 and will expire on 30 September 2026, or earlier, if either the maximum aggregate number of Common Stock has been purchased or the maximum aggregate consideration has been reached.

Due to the limited liquidity in the issued Common Stock, a buy-back of Common Stock pursuant to the Authority on any trading day may represent a significant proportion of the daily trading volume in the Common Stock on AIM and may exceed 25 per cent of the average daily trading volume. Accordingly, the Company will not benefit from the exemption contained in Article 5(1) of the UK version of the Market Abuse Regulation (Regulation (EU) No 596/2014) as incorporated into UK domestic law by virtue of the European Union (Withdrawal) Act 2018.
