Tenaga Nasional Bhd , Malaysia’s largest power group, said on Wednesday it has raised the takeover price for Integrax Bhd by 18.2 percent after a leading shareholder of the port operator rejected its offer. Tenaga, which counts Malaysia’s state investor Khazanah as a major shareholder, upped the takeover price to 3.25 ringgit per share from 2.75 ringgit previously, bringing the total value of the deal to some 761 million ringgit ($211 million). The revised offer was the price Perak Corporation Bhd , the second largest shareholder in Integrax with a 15.74 percent stake, suggested in a local stock exchange filing on Monday. Tenaga is currently the largest Integrax shareholder, with a 22.12 percent stake.
