Shareholders of Questar Corp. voted to approve the company's combination with Dominion Resources during a special meeting of shareholders at Questar's Salt Lake City headquarters.
More than 80 percent of the outstanding shares voted, with 96.6 percent approving the proposed merger.
Questar and Dominion announced the merger on Feb. 1, 2016. On Feb. 23, the Federal Trade Commission granted early termination of the 30-day waiting period under the federal Hart-Scott-Rodino Antitrust Improvements Act.
The only remaining conditions to the merger are approvals by the Public Service Commission of Utah and the Wyoming Public Service Commission. The companies filed for approval with utility regulators in both states on March 3. Subject to obtaining the necessary regulatory approvals, Questar and Dominion expect the transaction to close by the end of 2016.
