OM Group, owner of the Swedish stock exchange, has posted an operating loss of Skr535m (€58.5m) in the second quarter after being hit with a Skr624m restructuring charge related to its merger with HEX, the Helsinki exchange.

The company posted revenues of Skr595m, down from Skr612m in the first quarter. The loss was partly due to restructuring costs surrounding the closure of the company's Copenhagen and Edinburgh offices and the redundancy of 140 staff.
