Kenyan sports betting operator SportPesa has confirmed its new shirt sponsorship with English Premier League footballers Everton FC.

On Monday, SportPesa confirmed rumors that have swirled for months regarding the company’s tie-up with Everton. The club’s new kit, which will be unveiled on Tuesday, will feature SportPesa’s brand on its front as of June 1.

Terms of the five-year deal weren’t disclosed, but the club called it the “biggest commercial partnership” in its 140-year history. In January, Everton CEO Robert Elstone told investors that the new shirt deal represented a “threefold” rise over the club’s previous deal with Thai brewery Chang, which was worth £16m over three years, suggesting SportPesa could be paying up to £9.6m per year.

Elstone hailed SportPesa as “an ambitious and growing global company” that is “committed to significant investment not only into Everton through this partnership but also in the city.” SportPesa recently announced plans to shift its European HQ to Liverpool, a move that is expected to create around 100 local jobs.
