ARC Resources Ltd., a Calgary-based natural gas producer, says its shareholders have voted in favour of a previously announced takeover by Shell PLC for about $22 billion. The deal, disclosed in April, would see Shell acquire ARC Resources, a transaction described by local reporting as one of the largest for Canada’s oil and gas sector in many years. Multiple outlets report that the approval comes from a vast majority of ARC’s shareholders, indicating broad backing for the proposal. The company’s announcement confirms that the shareholder vote supports the planned acquisition process.
