As previously announced, on August 5, 2018, Connecticut Water Service, Inc., a Connecticut corporation (the “Company”), SJW Group, a Delaware corporation (“SJW”), and Hydro Sub, Inc., a Connecticut corporation and a direct wholly owned subsidiary of SJW (“Merger Sub”), entered into a Second Amended and Restated Agreement and Plan of Merger (the “Merger Agreement”). 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.

On January 23, 2019, the Company and SJW issued a joint press release announcing that The Maine Water Company, a wholly owned subsidiary of the Company (“MWC”), voluntarily requested to withdraw its application before the Maine Public Utilities Commission (“MPUC”) in connection with the proposed Merger. MWC’s request was made without prejudice and it reserves the right to refile its petition. The Company and SJW noted that the voluntary withdrawal aligns the Maine regulatory process with the regulatory process in Connecticut. As previously disclosed by the Company, the Company and SJW withdrew their joint application before the Connecticut Public Utilities Regulatory Authority (“PURA”) for approval of the proposed Merger on January 9, 2019. The companies are evaluating their regulatory approach in connection with the Merger, including the possibility of submitting a new application to the PURA.

A copy of the joint press release is filed as Exhibit 99.1 to this current report on Form 8-K and is incorporated herein by reference.

The information contained in this current report on Form 8-K, including Exhibit 99.1 attached hereto, is being furnished and, as a result, such information shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) or otherwise subject to the liabilities of that section, nor shall such information be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such filing.
