Item 7.01 Regulation FD Disclosure

On April 19, 2018, Connecticut Water Service, Inc. (the “Company”) issued a press release confirming that after it entered into the Agreement and Plan of Merger, dated as of March 14, 2018, among SJW Group, Hydro Sub, Inc. and the Company (the “Merger Agreement”), the Company received a non-binding, unsolicited acquisition proposal from Eversource Energy for $63.50 per share in cash and/or Eversource Energy common stock at the election of the Company’s shareholders. The Board of Directors of the Company has unanimously determined that Eversource Energy’s acquisition proposal does not constitute, and is not reasonably likely to lead to, a “Superior CTWS Proposal” as that term is defined in the Merger Agreement.

The information contained under this Item 7.01 of this current report on Form 8-K 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 (the “Securities Act”), or the Exchange Act, except as shall be expressly set forth by specific reference in such filing.

Item 8.01 Other Events

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