California Water Commends the Unanimous Decision by San Jose City Council to Request the California Public Utilities Commission Review of Proposed SJW Group and Connecticut Water Merger

Decision Follows Concerns Voiced by San Jose Mayor

85% of SJW’s Service Area Voters Recently Polled Believe the Connecticut Water Merger Should Be Reviewed by CPUC

SAN JOSE, Calif.--(BUSINESS WIRE)-- California Water Service Group (“California Water”) (NYSE:CWT) today commended the San Jose City Council on its unanimous decision to formally request that the California Public Utilities Commission (CPUC) review the proposed merger of SJW Group (“SJW”) (NYSE: SJW) and Connecticut Water Service (“Connecticut Water”) (NYSE: CTWS). The request is the result of a motion passed by the San Jose City Council on June 5, 2018, which was approved by a vote of 11 to zero.

The request follows concerns raised by San Jose Mayor Sam Liccardo regarding “the potential harms to San Jose’s one million residents” posed by the SJW/Connecticut Water transaction and his request for the CPUC to review the proposed merger. Mayor Liccardo outlined his concerns in a recent letter to CPUC President Michael Picker.

Separately, California Water released the results of a recent poll of registered voters living in San Jose Water’s service area¹, which found that the overwhelming majority of polled voters think it is important for the CPUC to review the proposed SJW/Connecticut Water merger and many are opposed to the proposed transaction. Specifically:

• 85% of poll participants believe that the transaction should be reviewed by the CPUC;
• 85% of poll participants believe that their elected officials should ask the CPUC to review the transaction;
• There is two-to-one opposition to the proposed SJW/Connecticut Water merger amongst participants; and
• Six times as many poll participants are strongly opposed to the proposed merger between San Jose Water and Connecticut Water Service compared to those who strongly support it.

“We believe the decision by the San Jose City Council yesterday, combined with Mayor Sam Liccardo’s letter and these polling results, demonstrate overwhelming concern by the San Jose community over the proposed merger between SJW and Connecticut Water,” said Martin A. Kropelnicki, President and CEO of California Water. “In our view, California Water’s proposed common-sense combination with San Jose Water would provide significant benefits to the customers, local communities, and employees that cannot be achieved by joining forces with Connecticut Water, an East Coast utility located 3,000 miles away. We urge San Jose Water to take note of these concerns voiced by customers and leaders in its own backyard, and question whether its proposed merger with Connecticut Water is truly in the best interests of the customers and communities it serves.”
