Sun Pharma acquired Ranbaxy in 2014 in a $4 billion deal to become the largest pharmaceutical company in India and fifth largest globally. The acquisition made Sun Pharma the largest Indian pharma company in the US and provided Ranbaxy with API manufacturing capabilities to resume exports to the US. However, Sun Pharma also assumed $800 million of Ranbaxy's debt and regulatory issues remain resolving quality issues at Ranbaxy's plants that were banned by the USFDA. The merger aimed to create synergies but was expected to negatively impact Sun Pharma's financial performance in the near term.
