Global private equity firm Warburg Pincus has acquired a 32 percent stake in India-based Laurus Labs, a developer and manufacturer of active pharmaceutical ingredients, for INR5.5 Billion (approximately US$90 million). The company had previously raised a financing round from Fidelity Growth Partners India (FGPI), the private equity arm of Fidelity International, and Fidelity Biosciences, a United States-based division of Fidelity International, in 2012. FGPI and Fidelity Biosciences have reportedly partially exited their stakes in this transaction.
