MEG estimates rail volumes to average 20,000 bbls/d in the first quarter, increasing to 30,000 bbls/d by the third quarter of 2019.
Adjusting for certain one-time items, the company posted a loss of 40 Canadian cents per share against expectations of a loss of 24 Canadian cents, according to IBES data from Refinitiv.
