Sumitomo Corporation is reportedly considering taking full control of Emerald Group Australia Pty Ltd. after buying its initial stake in 2010. Alan Winney, Head of Emerald, would not confirm if Sumitomo had made advances. "There are lots of people that are asking but we are not interested in selling," Winney said.

“There is too much upside in this business. There are great growth opportunities. We want to expand and acquire more than anything else.”
