LOS ANGELES— TOMS has completed the sale of a 50 percent equity stake in the company to Bain Capital LLC, a leading private investment firm. The partnership and investment support, a deal originally announced in August by the two companies, “will accelerate the growth of the company and its giving programs around the world, with TOMS’ founder, Blake Mycoskie, continuing as visionary of the company and the 50 percent owner of TOMS.”

Founded in 2006, TOMS began as a shoe company that matched every pair of shoes purchased with a pair of new shoes given to a child in need—One for One. Since then, TOMS’ giving has grown to serve other basic needs. TOMS Eyewear, launched in 2011, gives sight to a person in need with every pair of eyewear purchased, and TOMS Roasting Co. gives one week of clean water to a person in need for every bag of coffee purchased. To date, TOMS has given over 35 million new pairs of shoes to children in need and helped restore sight to more than 275,000 people, the company said.

“The partnership with Bain Capital will bring added resources and expertise to allow us to accelerate the growth of our company and the One for One mission globally,” said Mycoskie. “We are seeing increased demand for our products and brand and this partnership will help us meet that demand as we expand product categories and grow our distribution and retail footprint in key target countries internationally.”

“TOMS is very clearly the leading mission-driven company. It has a brand that stands for social impact in an authentic, unique and resonant way. We look forward to partnering with Blake and his team to grow the business while simultaneously growing and supporting the impact of its mission,” said Ryan Cotton, a principal at Bain Capital.
