Epoch, which rebranded from Clarke Mulder Purdie two years ago, will sell 100 per cent of its equity to the MDC Partners-owned agency, subject to customary closing conditions.
Kwittken & Co itself was only bought by US marcoms group MDC Partners in September 2010 and the Epoch deal represents the group's first PR agency acquisition outside of North America. The terms of the deal remain undisclosed.
Epoch will change its name to Kwittken & Co and maintain the same management team and staff, reporting to Aaron Kwittken, CEO and managing partner of Kwittken & Co worldwide. Kwittken & Co opened a UK office last year, but the deal will see it boost its London headcount from just four to 15.
Kwittken said the acquisition provided 'the perfect platform to service out multinational clients with cross-border needs'.
He explained that, shortly after establishing a European operation, Kwittken & Co's management team felt it needed to make a strategic acquisition to boost its UK presence and reviewed about a dozen agencies as part of that process.
Overall, Kwittken & Co now has 45 staff and has grown by 45 per cent since it was acquired by MDC. Kwittken said the agency expected to have double-digit growth year-on-year in revenues and headcount, including the UK operation.
Epoch was founded in 2004 by Christopher Clarke and Sarah Mulder, who will continue to lead the London operation. Clarke will take the role of general manager, while Mulder will be MD.
Clarke said the two agencies 'share a complementary global approach to comms that is based on ideas, creativity and thought leadership'.
