Management Commentary Commenting on the performance, Mr. Sanjay Dighe, CEO & Whole Time Director, Krystal Integrated Services Ltd, said, Krystal Integrated Services Limited took a strategic step toward strengthening its presence in infrastructure-linked services through the acquisition of Citelum India Private Limited, a company operating in the city lighting and urban infrastructure services segment. Urban infrastructure in India is witnessing growing investment driven by urbanization, increasing focus on energy efficiency and public infrastructure development. As cities increasingly adopt technology-enabled street lighting systems that improve energy efficiency, monitoring and asset management, demand is rising for service providers capable of delivering both installation expertise and long-term operations and maintenance of lighting infrastructure. Citelum India operates in this segment offering services across the design, engineering, installation and maintenance of street lighting and city lighting infrastructure with extensive experience in delivering connected lighting solutions and managing lighting assets. The proposed acquisition will enable Krystal to integrate Citelum India’s technical capabilities with its existing operational strengths in integrated services and technical maintenance enhancing its ability to participate in infrastructure-linked opportunities requiring specialized engineering expertise and long-term service delivery. Citelum India will operate as a wholly owned subsidiary of Krystal Integrated Services Limited, supporting the Company’s strategy of expanding into adjacent infrastructure service verticals and strengthening its positioning in city lighting and urban infrastructure services. Commenting on the performance, Mr. B Sivakumar, CEO & Director, Citelum India Private Limited, said, “The acquisition by Krystal Integrated Services Limited marks an important milestone in Citelum India's growth journey. Over the years, we have built strong capabilities in delivering city lighting and urban infrastructure solutions across India and becoming a part of the Krystal Group provides us with an opportunity to further strengthen and scale these capabilities.
