("Boku" or the "Company")

EXTENSION TO SHARE BUYBACK PROGRAMME

Boku (AIM: BOKU), a leading provider of mobile payment solutions, announces that its board of directors has approved an extension to the share buyback programme, which commenced on 7 July 2022, for a further twelve months from the expiry of the original programme term. The purpose of the Extended Buyback Programme is to hold the Common Stock in treasury for the purpose of satisfying future obligations in relation to equity issuance.

The extended programme will involve the repurchasing of common stock with par value of $0.0001 per share in the capital of the Company ("Common Stock") up to an additional maximum aggregate consideration of £10.5 million and up to an additional maximum of 5.25 million Common Stock (the "Extended Buyback Programme").

The Company has instructed Peel Hunt LLP, the Company's broker, to conduct the Buyback Programme on its behalf. The Buyback Programme 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 5 day average mid-market price, and in accordance with the authority granted by the Company's Board (the "Authority").

The Buyback Programme will be effective from the date of this announcement and will expire on 30 June 2024, or earlier, if either the maximum aggregate number of Common Stock have 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.
