Does Roark want to buy Pet Supermarket? Woof!

Roark, which already owns Pet Valu, has been working to close a deal for Pet Supermarket, a banker said. It’s unclear how much Roark would pay for the company.

The seller is Charles West Jr., who founded Pet Supermarket more than 40 years ago, the FTC filing said.

Sunrise, Fla.-based Pet Supermarket operates more than 150 stores. The company sells food and supplies for dogs, cats, fish, reptiles and other small pets, according to its website. The company produced $213 million in 2011 revenue, a report from the Sun Sentinel said.

In 2009, Roark acquired Pet Valu, a pet supplies retailer in Toronto. Pet Valu then bought Bosley’s Pet Food Plus Inc, a pet food and supplies retailer based in Vancouver, in 2010.

Roark’s investment in Pet Supermarket would come from its third fund, the FTC website said. Roark’s third pool closed at $1.56 billion in 2012. The PE firm has since raised its fourth fund, Roark Capital Partners IV, which closed in January at $2.5 billion.

Fund III was generating a 10.17 percent net IRR as of Sept. 30 and a 1.1x total value multiple, according to the Washington State Investment Board.

Roark, an Atlanta private equity firm, invests in franchise businesses such as restaurants and retail. Among its portfolio companies is Focus Brands, the parent of Auntie Anne’s, Carvel and Cinnabon. Roark also targets sectors such as consumer products, direct marketing and environmental services.

Roark Capital, Pet Valu and Charles West could not immediately be reached for comment.
