This was the first ever multi-team T20I tournament to be played in Malawi.
Four teams competed: hosts Malawi along with the national teams of Bahrain, Germany and Tanzania. This was the first international assignment for Tanzania under their new head coach Salieg Nackerdien, whose son Imran Nackerdien had earlier coached the Tanzanian men's under-19 team to their first-ever Under-19 World Cup and the senior women's team to a title win at the 2025 Kwibuka T20 competition.
On 4 July, a day before the tournament began, the schedule saw slight changes (including the game between Bahrain and Tanzania getting shifted from 5 July to 8 July) due to an equipment delay.
