Addleshaw Goddard is advising Sheffield-based Sumo Group plc on its £145m IPO, which was announced today and will be effective on 21 December.

The deal is 100th company floatation of 2017 and breaks the century barrier for the London Stock Exchange for the first time in three years.

A 70 strong AG team consisted of lawyers in AG's Manchester and Leeds offices, and was led by partner Roger Hart and included Jamie Partridge, Rachael Norris, Ben Collins, Shannon Hardcastle, Millie Johnson, George Danczak, David Handy, Kate McGough, Tom Rowen, James Whittam, Lauren Wills-Dixon, Andrew Vernon and Tom Ward.

The AG team also advised the independent games developer early this year on its acquisition of design studio Atomhawk Design Ltd – an acquisition which strategically supported Sumo Digital's plans to become a powerhouse for high quality creative and development services.
