GlaxoSmithKline plc, on Monday, said it had successfully increased its stake in its publicly-listed Indian pharmaceuticals subsidiary GlaxoSmithKline Pharmaceuticals Ltd. from 50.7 per cent to 75 per cent.

This was done by a voluntary open offer made by its subsidiary GlaxoSmithKline Pte. Ltd., a statement from GSK said.

The offer of Rs.3,100 per share values the transaction at about Rs.6,400 crore, and the final payment for shares tendered and accepted will be completed on or before March 20.
