Tees advises on sale of GTES Holdings to STS Aviation Group

Tees has advised long-standing client Greg Macleod on the sale of GTES Holdings Limited to STS Aviation Services, part of the STS Aviation Group.
GTES Holdings Limited is the holding company of GT Engine Services Limited (GTES), a jet engine care business based at Stansted Airport. GTES offers a wealth of aircraft maintenance, repair and overhaul (MRO) services and is one of the world’s leading aircraft repair and engine maintenance companies. GTES works with some of the biggest names in global aviation and seeks to provide engine management services in accordance with current Civil Aviation Authority (CAA), European Union Aviation Safety Agency (EASA) and Federal Aviation Administration (FAA) quality standards.
STS Aviation Services (STS), part of the STS Aviation Group, provides aircraft MRO services globally. STS is now the largest independent MRO in the United Kingdom and has an expanding footprint in Europe. The acquisition of GTES by STS builds on its strategy of being a single point solution for MRO services and further promotes STS’ growth ambitions.
Greg Macleod, former CEO of GTES, said: “The team at Tees worked tirelessly to put this deal together, offering valuable advice and support, their communication was top class even when we were faced with dealing with parties across several time-zones. I am delighted with the result and would thoroughly recommend their services.”
Corporate Partners Lucy Folley and Baljeet Kaur led the transaction on behalf of Tees, overseeing a diverse team of experts who provided comprehensive support. The team included professionals from Tees commercial property team, led by Partner Daniel Fairs, who advised on the real estate elements for the various units occupied at Stansted Airport.
Lucy Folley said: “Working alongside Greg for many years, we have seen GT Engine Services achieve considerable growth. When Greg decided it was the right time to realise the value of his many years’ hard work and sell his shares in GT Engine Services, we were delighted to assist him. It was a pleasure to guide Greg through the legal process involved and we wish him and the STS team every success in the future.”
Mr Macleod will remain a key member of the senior leadership team at GTES in the role of Managing Director, Engine Services.
Tees worked closely with Rob Dukelow-Smith and Amie Goodlad of Forward Corporate Finance, who advised on the tax and financial components and assisted in constructing the deal. Peters Elworthy & Moore (PEM) advised on the tax and accounting aspects

Lucy Folley was a critical part of getting the deal done. Lucy's understanding of our business was essential in getting the deal across the line. Without her efforts, I believe that it would not have gone through. I cannot recommend her enough!

'Lucy Folley has been my main contact. One of Lucy’s biggest strengths is her pragmatism. In a number of deals Lucy has been involved in, the counterparty in our negotiations has commented on how fair her approach is. This has made it much easier for us to close positions'
