Ranbaxy Laboratories Limited: A Legacy of Pharmaceuticals Ranbaxy Laboratories Limited, an Indian multinational pharmaceutical company, operated from 1961 to 2014. Its history is marked by significant transitions and ultimately, acquisition. Going public in 1973, Ranbaxy experienced two major ownership changes. In 2008, Daiichi Sankyo, a Japanese pharmaceutical giant, secured a controlling stake. However, Ranbaxy's final chapter involved its complete acquisition by Sun Pharma in 2014, an all-stock deal that marked the end of an era. This acquisition, by the world's fifth-largest specialty generic pharmaceutical company, brought in new management to address lingering controversies that had plagued Ranbaxy. The merger effectively integrated Ranbaxy's operations and assets within Sun Pharma's global network, concluding a chapter in Indian pharmaceutical history marked by both growth and substantial challenges. The legacy of Ranbaxy continues to influence the Indian pharmaceutical landscape.
