UK-based health, Safety and ESG risk management provider Alcumus announced today an investment by global private equity advisory firm Apax Partners for a controlling stake in the company. The transaction values Alcumus at over £600 million.

Founded in 1979, Alcumus helps organizations improve safety and sustainability through expertise and integrated products and services that anticipate, manage, and mitigate risks. Alcumus has grown to 750 employees and 45,000 customers, with offices in the UK, North America and APAC.

The Apax investment follows the stake sale of private equity investor Inflexion. Inflexion backed the £92 million buyout of Alcumus in October 2015, and supported the company’s £47 million acquisition of integrated health & safety and environment risk management services provider Santia. According to Inflexion, the sale marks its largest-ever cash return.

Alyn Franklin, CEO at Alcumus, said:

“Our journey with Inflexion has seen us transform from a consultancy business to a global leader in technology risk management solutions. Apax recognizes the success we have achieved in the last six years and the growth potential ahead. With such respected and high-profile investors, we are excited to continue our ambitious growth journey and global strategic plans with our unique combination of technology and people.”

Simon Turner, Managing Partner, Inflexion, said:

“Alcumus’ stellar growth is a testament to what can be achieved when a great business is led by a management team as capable as it is ambitious. It was a privilege to support their journey of international growth and transition to SaaS, and we are confident they have further to go given their strong product offering in a fast-growing, international market.”

Anders Meyerhoff, Partner, Apax, added:

“We have been incredibly impressed with the high-quality business and culture that Alyn and his team have built. We are excited to partner with such great people and look forward to further supporting Alcumus and all the employees as they create a safer and more sustainable world.”
