The acquired assets comprise over 100 affiliate sites and domains including state-specific websites such as Michigansharp.com and NYSportsDay.com, as well as US-wide websites like Bonus.com and Gamblingonline.com.
These assets generated combined revenue of approximately $8.0m during the 12 months to July 31, 2021.
Catena said the acquisition will help to strengthen its North American business, adding that it expects the purchase to have a direct positive effect on its earnings before interest, tax, depreciation and amortisation.
