California Water Announces Extension of its Cash Tender Offer for All Outstanding Shares of SJW Group

California Water Reaffirms Its Commitment to a Combination with SJW

SAN JOSE, Calif.--(BUSINESS WIRE)-- California Water Service Group (NYSE:CWT) (“California Water”) announced today it is extending the expiration time of its tender offer for shares of SJW Group (NYSE:SJW) (“SJW”) from 5:00 p.m., New York City time, on August 3, 2018 to 5:00 p.m., New York City time, on September 28, 2018. The extension is driven by SJW’s delay in calling its special meeting of stockholders to vote on the merger with Connecticut Water Service, Inc. (“Connecticut Water”).

California Water commenced the all-cash tender offer to acquire all outstanding shares of SJW for $68.25 on June 7, 2018. California Water’s offer represents a 30 percent premium over SJW’s closing stock price on April 3, 2018, the last trading day before California Water submitted its proposal to SJW in writing.

California Water continues to believe its tender offer provides far greater value to SJW stockholders and is therefore significantly superior to the highly conditioned proposed merger with Connecticut Water. Accordingly, California Water reaffirms its commitment to closing a combination with SJW.
