Analysts Remarks… “Connecticut Water had a transformative 2012, expanding from a single- state water utility into a regional player in New England with aims on further expansion. Through its two acquisitions into Maine, the company grew its customer base 35% while significantly diversifying its regulatory exposure.” (Janney, March 2013). “The company has instituted an asset management program which focuses on capital investment with corresponding rate cases, acquired several small tuck in water systems and most recently made two large scale system purchases. These actions should position CTWS well for improved growth..” (Boenning and Scattergood, March 2013). “CTWS' recent entry into Maine via acquisition provides ~30% customer growth, potentially boosting opportunities to invest capital and add tuck-in acquisitions, as well as diversifying the company's Connecticut regulatory risk.” (Baird, March 2013).
