Epiris today announces that Epiris Fund III, advised by Epiris LLP, has acquired LoneStar Group (“LoneStar”), a leading global manufacturer and supplier of high-performance fasteners, sealing products, precision-engineered components and pipeline packages for the world’s industrial and energy markets. This is the second investment for Fund III following completion of the take-private of Euromoney Institutional Investor plc in November. Financial terms are not being disclosed.

Headquartered in the West Midlands, UK, LoneStar supplies blue-chip customers worldwide from its manufacturing and distribution sites in the UK, USA and Middle East. Its components are required to perform in extreme environments where the cost of product failure, in both financial and safety terms, can be significant. LoneStar’s mission-critical products are therefore made to exacting tolerances, are subject to stringent testing and accreditation regimes, and are supplied within a fully-controlled quality system that ensures full traceability of components from raw materials to customer despatch.

Peter Williamson, with whom Epiris also works as Chairman of its portfolio company Diamorph, will join the group as non-executive Chairman.

Charles Elkington, Partner at Epiris, said:

“LoneStar is typical of the kind of business in which we seek to invest. It is a high-quality business: a global market leader with scale and clear competitive differentiation. It operates in attractive markets, benefiting from growing energy demand in both traditional and renewables. Most importantly, it is one which we believe we can transform by bringing our trademark focus on strategy, operational excellence and M&A.”

Alex Fortescue, Managing Partner at Epiris, said:

“LoneStar caps an exceptionally busy period for us with five new investments, including the final investments for Fund II and now the first two investments for Fund III. Deployment and performance of Fund III are off to a great start and we see an exciting environment ahead for our distinctive approach to investing.”

The Epiris team on the LoneStar investment is Charles Elkington, Zoe Lai, Pablo Espinoza, Scott Forbes and Nikki Lahiri. Epiris was advised by Latham & Watkins, Deloitte, Zeus Capital and LEK.
