Sportingbet has around a 30% share of the Australian online gaming market which provided the firm with around 90% of its profits.
“The Boards of William Hill and GVC believe that by acting in combination they represent a highly credible possible offeror for the entire Sportingbet business, substantially in cash,” read the joint statement.
A separate release from Sportingbet confirmed that its board has received no approach. William Hill and GVC have until 16 October to announce a formal offer.
