Sigma Pharmaceuticals Limited is a leading full line wholesale and distribution business to pharmacy. It is also the owner of two of Australia's best known pharmacy retail brands: Amcal Max, Amcal and Guardian.
2010 trading halt
In 2010, Sigma shares were placed in a trading halt on the Australian Stock Exchange – initially due to a profit warning. Since then, allegations of accounting irregularities and preferential deals negotiated with certain pharmacy chains (at the expense of smaller independent chemists) that left Sigma losing money at the expense of their own Amcal and Guardian Pharmacies banners and forsaking cashflow have emerged. The trading halt was lifted later that year. These events resulted in the initiation of a shareholder class action, which is before the Federal Court of Australia.
