G&T said the deal with Hennick & Company would preserve its independence creating a platform for growth and expansion throughout the UK, US and Ireland.
The size of the stake has not been disclosed but sees G&T continue as a Limited Liability Partnership with all 157 partners remaining long-term owners.
G&T’s entire senior leadership team, including its managing partner, Adam Glover, will remain in their current positions with full autonomy and control over day-to-day operations.
G&T presently employs 1,400 staff providing project management, cost management, infrastructure management and specialist consultancy.
As part of the transaction, HennickCo and G&T have established a clear process to expand its current ownership base over time to welcome the next generation of professionals into the partnership.
This new structure will allow the firm to drive growth in its core markets and beyond while ensuring that G&T continues to attract and retain the world’s most talented project and programme managers, cost managers, and other specialist advisors.
Adam Glover, managing partner of G&T, said “We are delighted to welcome HennickCo as a long-term investor and well aligned strategic partner.
Getting to know and learning to work with them over a number of months we have developed a unique partnership solution which we believe will benefit both organisations over the long term.
“Most importantly, we believe this new partnership will benefit our clients, strengthen our world-class service offering and provide even greater opportunity for our people in the years to come.
“Our equity partners were unanimous in their support for the new partnership and all partners will remain in their current roles.”
