Exercise of warrants

Boku, the world's leading independent direct carrier billing company, announces that application has been made to the London Stock Exchange for admission to trading on AIM of 543,760 new common shares of $0.0001 each ("Common Shares") pursuant to the exercise of all warrants issued to Silicon Valley Bank in connection with a loan and security agreement entered into between the Company and Silicon Valley Bank in February 2013. Silicon Valley Bank and therefore these Common Shares are subject to the lock-up arrangements described in the Admission Document.

It is expected that Admission will become effective and trading will commence at 8.00 a.m. on or around 3 October 2018.

The Company advises that, following Admission, the Company's issued share capital will be 222,857,944 Common Shares. No shares are held in treasury. As such the Company's total number of Common Shares with voting rights is 222,857,944.

The above figure of 222,857,944 may be used by shareholders as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change to their interest in, the Company under the FCA's Disclosure and Transparency Rules.
