The Hyderabad-based firm had raised Rs 316 crore in November 2019 from Bahrain-based PE firm InvestCorp. The company said the current round comes on the heels of a notable scale-up that the company has delivered in recent years towards maintaining its dominant market position in the dialysis space. In the last two years, the company added 80-plus centres in India, entered the Philippines market with acquisition of Royal Care Dialysis and bagged a significant $100 million dialysis contract in Uzbekistan, which includes building the world's largest dialysis centre in Tashkent. The company established 11 years ago treats 18,000 patients per month. NephroPlus operates 275 dialysis centres in more than 170 cities across 23 states in India and is known for its quality focus and patient-centricity.
