RE:Storm Development Corp. acquiring assets from ARC Resources I would speculate that they are already a little bit capex heavy with a 1.8 billion capital budget for 2023.
They may be trying to raise some cash to offset the Attachie expense that would be incurred in the 2023 year to take a little pressure off the balance sheet.
I think they want to sell those asset ahead of sanctioning the Attachie build out.
IMHO
