London-based marketing communications group MSQ Partners has secured a cash investment by private equity firm LDC, valuing the group at £37.5m.

MSQ Partners is a group of creative agencies with 15 international offices which including Leeds-based digital agency twentysix. It is the fastest growing multi-disciplinary group in the UK.

MSQ and its agencies operates from offices in London, Belfast, Bollington, Edinburgh, Glasgow and Leeds and internationally.

The investment is set to support further development of its multi-disciplinary model and its international roll-out.

Leading mid-market private equity firm LDC has invested significantly alongside senior managers in MSQ Partners, one of the UK’s fastest growing marketing communications groups, in a deal that values the business at around £37.5m.

It will enable the group to accelerate the roll-out of its successful multi-disciplinary model and support the continued growth of its individual agencies.

The deal marks an exit for NVM Private Equity, which first backed the business in July 2014.

Under the leadership of co-founder and CEO Peter Reid, MSQ Partners has grown rapidly and today supports an international client base of more than 300 businesses, which include blue-chip and household names such as PSA Group, Diageo and Unilever.

“Our team has worked incredibly hard over the past four years within their agencies and collectively to strengthen the range and depth of our individual capabilities and to refine our offer to clients,” said Peter Reid, CEO of MSQ Partners.

“We maintain a laser-like focus on quality and creativity and it is only with our employees’ and clients’ on-going support, and that of the team at NVM, that we have been able to deliver double digit annual growth over the period.”

John Clarke, Investment Director at LDC in Manchester, added: “Peter and the team at MSQ have built a truly formidable business that is able to provide full-service, marketing communications services on an international scale.”

The deal marks the second investment from LDC’s Manchester team in under two weeks and follows its £20million investment in Shield Group International.
