A portfolio company of Transom Capital Group, a Los Angeles private equity firm which specializes in the lower-middle market, acquired La Jolla skateboard maker Sector 9, the company announced today.

Bravo Sports, the portfolio company, bought the La Jolla-based company from Billabong International, which sells board sports clothes and gear.

Bravo Sports said in a press release that it was creating an action sports lifestyle division.

“We will foster the innovation and skateboard technology that’s at the core of Sector 9 while expanding it as a lifestyle brand worldwide,” said Mark Heineken, chief brand officer of Bravo Sports.

Sector 9 was started in 1993. The company makes most of its boards at its San Diego manufacturing facility.

Dennis Telfer, Sector 9 co-founder said it was a “time of change” for the brand.

“Bravo Sports has the knowledge and experience to take Sector 9 to the next level,” Telfer said in the press release.

Bravo Sports acquired Pro-Tec, a San Diego maker of protective sports gear, in December.
