California Water Withdraws $70.00 Per Share Proposal to Acquire SJW Group After Rejection by SJW

Terminates Tender Offer to Acquire Outstanding SJW Stock

SAN JOSE, Calif.--(BUSINESS WIRE)-- California Water Service Group (“California Water”) (NYSE: CWT) today announced that it has withdrawn its revised proposal to acquire SJW Group (“SJW”) (NYSE: SJW) for $70.00 per share in cash after it was rejected by the SJW Board. California Water will also terminate its tender offer to acquire all outstanding shares of SJW common stock.

“California Water is financially disciplined, and after repeated attempts to engage with the SJW Board of Directors, we believe it is in our stockholders’ best interests to withdraw our proposal and focus on other opportunities,” said Martin A. Kropelnicki, President and CEO of California Water.

Mr. Kropelnicki continued, “It is unfortunate that the SJW Board concluded that our offer was not likely to lead to a superior transaction without availing themselves the opportunity to enter into a single discussion with us. Although we are disappointed by their unwillingness to engage, we are confident we have an excellent growth strategy in place that will continue to deliver long-term stockholder value. As we build on our long track record of success, we will remain committed to enhancing the quality of life for our customers, communities, and employees.”
