Companies reporting:

MEG Energy Corp. shares plunged 35.6 per cent Thursday after Husky Energy Inc. abandoned its hostile takeover bid for the company. Husky, the much larger of the two oilsands-producing Calgary firms, surprised observers when it announced it would not extend the offer that expired Wednesday without receiving the needed two-thirds support. Meanwhile, Husky shares rose by 12.4 per cent to $17.45. Husky said in a statement it decided not to extend its cash-and-shares offer because of the lack of MEG board and shareholder support.
