Mirroring the global growth strategy of fellow UK financial comms shops Brunswick and FD, the deal is designed to help Finsbury significantly move beyond its UK roots.
Both Finsbury and Robinson Lerer & Montgomery are owned by WPP.
RLM Finsbury will operate out of offices in New York, London, Brussels, Dubai, Abu Dhabi and a newly announced office in Hong Kong, which will open during the third quarter of 2011.
Roland Rudd, founder and head of Finsbury, will be chairman of RLM Finsbury, while Walter Montgomery, a founder and current CEO of RLM, will be CEO. They will be supported by a board drawn equally from both businesses.
Rudd explained: ‘This is a strategically important development for both companies and is the culmination of working closely together for more than five years. RLM has a strong reputation in the US for its expertise in handling some of the most high profile and complicated corporate situations of the last 25 years.
‘Combined with Finsbury's expertise in M&A and reputation management, RLM Finsbury will offer clients a comprehensive communications solution across the key global financial centres.’
The newly combined agency will concentrate on crisis and reputation management, corporate positioning and public policy and regulatory issues as well as traditional capital markets, investor relations and financial media relations work.
Finsbury, founded in 1994, represents more than 30 companies in the FTSE 100. The agency's latest FTSE 100 win is pharma firm AstraZeneca, revealed by PRWeek yesterday.
