The owner of 888.com plans to list its shares on the London Stock Exchange at the end of September with a price range of 162-212p, which will value the company at between £546.1m and £714.6m.
The company said its net gaming revenues from the casino operations grew 14.2% in the first half of this year, while revenues from poker surged 226% in the same period.
Net gaming revenue from both casino and poker in July was $23.3 million, 12.5% more than the $20.6 million monthly average in the first half of the year.
The company’s directors expect further market share gains even if the poker growth rate slows.
“As one of the world\’s most popular online gaming companies we have a very strong story to tell in respect of our position and our future strategy for growth,” said the Chief Executive John Anderson.
“As a business, we have traded profitably over many years and I am delighted to report continued strong current trading.”
“In particular, the growth in the casino segment is very encouraging, given that historically trading results for the casino in July and August are the weakest for the year.”
