RD Capital Partners has bought an 80% stake in the Warwick-based construction firm founded in 2003.
The deal will see founder and CEO Keir Edmonds and the firm’s senior management team remain with the company and retain shareholdings in the business.
MCS employs more than 60 staff and turns over more than £112m for clients in the automotive, industrial, commercial, retail and leisure sectors.
Accounts for last year showed the firm generated a pre-tax profit of £6.65m.
Edmonds said the deal was designed to ensure that MCS maintained its strong financial performance.
“RDCP is building a group of successful companies with the aim of growing over the long term,” he said.
“It will be very much business as usual with us continuing to deliver great projects for our clients whilst maintaining our strategic objectives of minimising and managing risk to maximise returns.”
RD Capital Partners is a diversified investment group with an enterprise value of £500m, employing 2,000 staff across multiple sectors in the UK.
It was founded in 2015 by Sameer Rizvi and Iryna Dubylovska and has made 31 investments, which have consolidated into ten ring-fenced companies in sectors including care, engineering, transport, leisure and building products.
Rizvi said: “We have closely followed the progress of MCS and have been impressed by its performance, quality and consistency in what is a very competitive sector.
“Keir and his team have created a strong business and, as investors, our aim is to allow them to continue to follow that path and keep producing very healthy results, as well as exploiting any synergies within our group companies.”
