(Reuters) -Canadian oil sands producer MEG Energy shareholders on Thursday voted in favor of a buyout by Cenovus Energy, ending a months-long takeover battle.

Cenovus and Strathcona had been locked in a bidding war for MEG, one of Canada's last pure-play oil sands producers. However, Strathcona backed Cenovus after it amended its bid and raised the offer price to about C$30 per share.

On October 30, MEG Energy further postponed the shareholder vote on Cenovus's buyout offer to November 6, citing a regulatory inquiry that required additional disclosures. The vote was initially delayed from October 22 to October 30 after Cenovus exercised its right to defer.

The regulatory inquiry was related to a complaint raised by a former employee of MEG who holds approximately 4,000 shares, Cenovus CEO Jon McKenzie said on a conference call last week.

According to the results, 86% of shareholders voted in favor of the transaction.
