The company had posted a net profit of Rs 2,050.22 crore for the corresponding period of the previous fiscal, Sun Pharmaceutical Industries said in a statement.
Consolidated net sales of the company declined to Rs 6,803.31 crore for the quarter under consideration as against Rs 7,979.31 crore for the same period year ago.
Commenting on the results, Sun Pharma Managing Director Dilip Shanghvi said: "Our performance for the quarter and first half FY16 has been impacted by lower sales growth, volatile currency movements and supply constraints."
Earlier this month, addressing the company's shareholders during the annual general meeting (AGM), Shanghvi had said that in the near term and especially for 2015-16 fiscal, the company's overall growth in revenues and net profit will be adversely impacted due to temporary supply constraints at Halol plant.
