The club was formed in 1999 as "BV Chemnitz 99" by the fusion of the clubs
BG Chemnitz and
Lok Chemnitz. In 2001, BV Chemnitz 99 began a cooperation with the
Chemnitz University of Technology, which is why "TU" was added to the team name. In the summer of 2002, the division of the men's team (BV TU Chemnitz 99) and the women's team (
Chemcats Chemnitz) followed. For the men's team, the nickname
Niners evolved through the foundation year 1999. On 28 May 2015, Chemnitz hired Argentine
Rodrigo Pastore as new head coach. In 2017, the nickname Niners was officially adopted as new club name. In the 2019–20 season, Chemnitz was highly successful until the season was declared void due to the
COVID-19 pandemic. Based on its first place in the standings, the Niners were promoted to the
Basketball Bundesliga for the first time in club history. The Niners entered the qualifying rounds of the
2022–23 Basketball Champions League, making their debut in European competition. In their second European season, the Niners won the
2023–24 FIBA Europe Cup championship, their first trophy in club history. They became the second German team to win the competition. ==Season by season==
