Puma has announced plans to buy a stake of up to 5 percent in Borussia Dortmund, a leading German football team that it sponsors, as part of a capital increase that the club unveiled on Aug. 21. Borussia Dortmund is Germany's only listed football club. Dortmund plans to issue up to 24.5 million shares in a capital increase worth up to €114.4 million. The offer ran from Aug. 26 through Sept. 8, but the results have not yet come out. The club's main sponsors — Puma, Signal Iduna and Evonik Industries — committed to buying up to 17.6 million of the shares, or up to four new shares for each 11 old shares they hold. Puma has been the club's technical partner since 2012, providing official playing kits for all associated Borussia Dortmund teams, including the senior men and youth teams as well as replica kits, fan wear and other merchandise. Dortmund is following in the footsteps of Bayern Munich, which has already sold stakes in its club to commercial partners Adidas, Audi and Allianz.
