Simon Parrington, Founder and Chief Executive Officer of Celnor Group, said:

"In three years, we have built a strong international platform, underpinned by exceptional people, trusted brands and a shared commitment to our customers. Partnering with Goldman Sachs is an important next step in our long term strategy and will enable us to invest further in our people and capabilities, strengthen our proposition for clients and create new opportunities for colleagues across the Group. I would like to thank Inflexion for its invaluable support since day one and am delighted they will continue as a partner in our next chapter."

Jose Barreto, Partner within Private Equity at Goldman Sachs Alternatives, said:

"Having built a close relationship with Simon and the management team since Celnor's formation, we are delighted to invest in the business at this hugely exciting stage in its evolution. We've been very impressed by Simon and the management team's track record of building and scaling the Group via M&A, while maintaining a clear focus on its customers, its service quality and importantly, its people. We look forward to partnering alongside Inflexion and management to drive future growth, both in the UK and internationally."

Harry Wilson, Investor within Private Equity at Goldman Sachs Alternatives, added:

Simon and the team have executed the strategy incredibly and we look forward to continuing to support them as a minority shareholder."

Dominic Clark, Investment Director, Inflexion, added, "Celnor is an example of buy-and-build done well: a clear strategy, a disciplined and relationship-led approach to acquisitions, and sustained investment in the businesses once they joined. That combination has developed deep technical expertise across the Group, delivered at scale, and there is significant runway ahead - particularly in the US and Continental Europe - and we are proud to remain part of Celnor's story alongside Simon, the team and Goldman Sachs."
