Last week, in one of the biggest news stories (for us) so far this year, Southwestern Energy announced it is buying out and merging in Montage Resources (see Stop Press! Southwestern Energy Buying Montage Resources for $857M). The combined companies will create the third-largest (by acreage) Marcellus/Utica driller. Yet investors have pretty much yawned. The company’s stock went down after the announcement. According to one analyst, Southwestern’s purchase is a “grand slam” home run and investors should sit up and take notice.
