CUMI to acquire controlling stake in PLUSS
Carborundum Universal Ltd. (CUMI) has agreed to buy a controlling stake in PLUSS Advanced Technologies Pvt. Ltd. at an initial investment of ₹115 crore, or about $15.7 million USD.
Pluss, based in Gurgaon, India, develops and manufactures phase change material and other specialty materials for use in the automotive, health care, construction, energy and temperature-control packaging sectors.
“We started as a bootstrapped business in 1994,” Samit Jain, right, managing director of PLUSS, said in a news release. “Now, we are getting into Phase 3 of growth, where our focus is on quick introduction of commercialized products through infrastructure creation, continuous innovation, license technologies and strategic partnerships. We welcome the investment from CUMI, part of the Murugappa Group, as our strategic partner. With CUMI’s experience in material sciences, global footprint and coupled with their investment capabilities, we are confident of accelerating the progress of PLUSS.”
Sridharan Rangarajan, director of finance and strategy at CUMI, described PLUSS as “a niche technology company with good growth prospects.”
“Opportunities in pharma cold chain, refrigeration & food supply chain, medical devices, buildings and HVAC are emerging in India as well as globally,” Rangarajan said. “PLUSS with CUMI’s global footprint and investment support is well poised to address these opportunities.”
