NOVEMBER, MANCHESTER: Foresight Group (“Foresight”), a leading listed infrastructure and regional private equity investment manager, has announced the exit of ONFAB Limited (“ONFAB” or the “Company”) to US life sciences business, Savillex.

ONFAB is a producer of high potent enclosures used in small molecule and biopharmaceutical drug manufacture, which enable pharmaceutical sponsors, researchers and suppliers to manufacture next generation drugs safely and consistently.

The initial investment, which was made in 2017, enabled the founder to exit the business, with Foresight investing a total of £9m over the hold period. Foresight introduced a Chairperson alongside Managing and Finance Directors, invested in new products and drove improved governance and sustainability practices, creating a significant number of high-quality jobs. The business rapidly expanded globally, facilitating the fast development and production of life changing drugs.

Today, ONFAB is a leading name in the safe manufacturing of small molecule and biopharmaceutical drugs, serving global clients at the forefront of these high-growth markets.

Foresight will retain a majority interest in ONFAB’s remaining group company, Envair Technology Limited (“ETL”), which manufactures rigid isolators for pharmaceutical and pharmacy applications.

To date, this investment has generated a 3.2x cash-on-cash return for investors in Foresight’s first fund focused on North West England, the Foresight Regional Investment Fund. The future realisation of ETL is likely to generate significant additional proceeds.

Chris Wardle, Managing Director at Foresight Group, comments: “It has been a pleasure to work with Mark, Mike and team over the past six years. They have worked tirelessly to build ONFAB into a global brand that is recognised as the gold standard in pharmaceutical containment. It has been a fascinating journey and we wish them all the best as they continue to capture this exciting market opportunity with Savillex.”

Mark Arnold, Managing Director of ONFAB, comments: “A big thank you to Foresight for enabling the development of the ONFAB business and driving our international growth strategy, with particular thanks to Chris Wardle for his support and dynamism. It has been a pleasure to work together, and the team and I are looking forward to working with our new partners, Savillex and Thompson Street.”
