Sun Pharma has become one of the world's most profitable generic drug makers over the past 30 years, with a net profit of Rs. 516.55 crore in fiscal 2013 making it India's largest pharmaceutical company by market value. An investment of Rs. 100,000 in Sun Pharma's 1994 IPO would have grown to around Rs. 3.3 crore by December 2012 and close to Rs. 4 crore with current stock prices, due to two stock splits in 2010 and 2012 that increased the number of shares.
