Healthia Limited is planning a ASX listing in 2018, that could value the company as much as $80 million as it seeks to tap growing demand for podiatry services. Healthia is seeking to offer shares to the public in the first half of the year to help fund an aggressive expansion of its current network of 50 clinics. Healthia Chief Executive Darren Stewart said the listing would help the company, founded from a single suburban clinic in 2004, to expand to 200 outlets.
