On December 3, 2018, the Connecticut Public Utilities Regulatory Authority (“PURA”) issued a proposed decision that would deny the joint application by Connecticut Water Service, Inc., a Connecticut corporation (the “Company”), and SJW Group, a Delaware corporation (“SJW”), for the approval of a change of control of the Company in connection with the previously announced Second Amended and Restated Agreement and Plan of Merger (the “Merger Agreement”), dated as of August 5, 2018, among the Company, SJW and Hydro Sub, Inc., a Connecticut corporation and a direct wholly owned subsidiary of SJW (“Merger Sub”). Pursuant to the Merger Agreement, Merger Sub will merge with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned subsidiary of SJW.

Following their review of the proposed decision, the Company and SJW filed with PURA today a motion to extend the statutory time period within which PURA’s proceeding must be concluded to allow the applicants to address the concerns raised by PURA in the proposed decision. The proposed decision is not the final determination by PURA with respect to the Company’s and SJW’s application and notes that PURA will consider the parties’ arguments and exceptions before reaching a final decision.

On December 3, 2018, the Company issued a statement regarding PURA’s proposed decision. A copy of the statement is filed as Exhibit 99.1 to this current report on Form 8-K and is incorporated herein by reference.
