Epiris, a private equity company, completed the acquisition of LoneStar, a high performance fasteners, sealing and precision engineered components manufacturer, from AEA, an investment company. Financial terms were not disclosed. “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,” Charles Elkington, Epiris Partner.
