"Two years ago the board adopted a strategy to focus on our profitable, long-life assets in Chennai and to deleverage in order to deliver growth in shareholders' equity by the transfer of value from debtholders to investors,” Arvind Gupta, OPG chairman said in a statement. “This process continued successfully during the first half of this financial year.”
He added: “By maintaining our sector leading operational performance, we intend to sustain the rate of term debt repayment with the objective that in 2023 we will be debt free. As interest costs decline in line with borrowings we will generate increasing levels of free cash flow which, in due course, will increase shareholder value substantially."
OPG shares rose by 15% to trade at 18.58p.
