RBC analysts cited the new CEO of AltaGas, Vern Yu, as a positive catalyst for the stock. Yu spent three decades at Enbridge, one of the largest gas utilities in North America, and most recently served as chief financial officer and president of its 'new energy technologies' division. "We positively view Vern Yu's first conference call as the new CEO, which started with messaging on reducing risk and volatility in the business via a higher degree of contracting for both existing cash flow and future growth projects," the analysts said in a note to clients on August 1.
