ECA makes a solid case for value uplift, and purchasing assets counter cyclically is what we all argue should be done. The increased dividend and repurchase commitment show material confidence, as does CEO Suttles buying 50k shares. Lloyd Byrne, UBS (November 12, 2018) We view this acquisition as being positive in the longer-term given the cash flow accretion, improved balance sheet metrics and the addition of ~360,000 net acres of SCOOP/STACK exposure. Dennis Fong, Canaccord Genuity (November 1, 2018) The deal provides another platform with significant scale for ECA to utilize its successful cube development technique. Phil Skolnick, Eight Capital (November 1, 2018) In our view the deal holds merit and provides an opportunity for additional oil/liquids growth out of the STACK.
