Retail Zoo, the owner of Boost Juice and Salsa’s, is considering a sale or a public listing on the Australian Stock Exchange (ASX).

The group, which was founded in 1998 by Boost entrepreneur, Janine Ellis, has been looking at its options with investment bank, UBS.

Retail Zoo is 70 per cent owned by US private equity firm, The Riverside Company, which took a major stake in the Australia-based group in 2010.

The firm is more inclined to sell than opt for a public listing, according to The Australian.

Boost Juice has built up almost 200 stores since launching 15 years ago, when it led a smoothie and juice craze across Australia.

It has had its market challenged in the last five years by new entrants, as well as the growth of boutique juices for sale in supermarkets.

It launched Salsa’s Fresh Mex Grill only a few years ago, with the quick service restaurant chain pitting itself against the likes of Mad Mex.

The group acquired Cibo Espresso, an Adelaide-based coffee bar, in late 2012, leading to a sharp raise in annual revenue.

Its last financial year sales grew by 30 per cent, with an annual turnover of $221 million compared to $170 million the year before.

The group, which is headed by Scott Meneilly, has been targeting overseas markets in the last few years, such as China.

Almost 60 stores opened in the Retail Zoo network in the year to 30 June 2013.
