Lululemon Says Its Founder Has Advised Rivals Alo and Vuori

Lululemon Athletica Inc. says founder Chip Wilson has advised competitors Alo and Vuori amid his long-running spat with the company.

The relationship between Wilson, one of the retailer’s biggest investors, and the two upstart yoga brands was disclosed in Lululemon’s preliminary proxy filing on Tuesday. The document also includes details about Wilson’s communications with the board over the past several months as he has pushed for a shakeup at the company, criticizing its management and pitching his own slate of directors.
