"At no point has KKR approached Punj Lloyd to buy out its stake in Medanta," the company said in a statement.
It termed as "speculative and incorrect" reports that Punj may sell the stake to cut its debt.
Medanta Medicity Hospital, co-promoted by cardiac surgeon Naresh Trehan and Sunil Sachdev who holds around 54 per cent stake, is spread over 50 acres and has a capacity of 1,250 beds and over 350 critical care beds and 45 operation theatres. Punj Lloyd holds 17 per cent stake in the hospital.
