Chemist Warehouse chief executive Mario Verrocchi says the retailer could become the next Walgreens or Boots and expand rapidly overseas after becoming an $8.8 billion ASX-listed pharmacy giant following its merger with Sigma Healthcare.

Mr Verrocchi, flagging a 100-year growth strategy, said it was a “life dream” to list the company, which has more than 600 stores in its network. Together with his billionaire co-founders, Jack Gance and Sam Gance, Mr Verrocchi will own almost 50 per cent of the combined company.
