Super Group Completes Warrant Exchange Offer and Consent Solicitation

Super Group Completes Warrant Exchange Offer and Consent Solicitation

January 10, 2023

Cooley advised Super Group, the holding company for top global online sports betting and gaming businesses Betway and Spin, on the completion of its public warrant exchange offer and warrant consent solicitation, as well as its related earnout shares waiver. Jointly, the measures removed the potential issuance of approximately 78.8 million of Super Group’s ordinary shares, lowering Super Group’s potential fully diluted share count by 13.6%. The exchange offer and consent solicitation simplified Super Group’s capital structure, increased its public float and reduced the potentially dilutive impact of the warrants.
