Sigma Healthcare (ASX:SIG) shareholders Jack and Sam Gance, the brothers who helped found Chemist Warehouse, remain committed to the company and have no plans to sell more than 20% of their respective stakes once the shares are released from escrow, according to a Thursday filing with the Australian bourse.

The company said about 2.72 billion Sigma Healthcare shares held by the Gance brothers will be released from voluntary escrow at the close of trading on Aug. 27.

Another roughly 2.3 billion shares held by Mario Verrocchi, another founder of Chemist Warehouse, will also be released on the same date, but Verrocchi does not plan to sell any of his shares in the near term, per the filing.
