CALIFORNIA WATER COMMENCES CASH TENDER OFFER TO ACQUIRE

SJW GROUP AT $68.25 PER SHARE

Urges SJW to Engage and Requests Cooperation to Begin State Regulatory Review Process

SAN JOSE, Calif. — June 7, 2018 — California Water Service Group (“California Water”) (NYSE: CWT) today announced that it has commenced a tender offer to acquire all outstanding shares of SJW Group (NYSE: SJW) for $68.25 per share in cash. The offer is scheduled to expire at 5:00 p.m., New York City time, on August 3, 2018, unless the offer is extended.

On April 4, 2018, California Water made a private proposal to acquire SJW for $68.25 per share in cash, which exceeds SJW’s all-time high closing share price, and represents a 30% premium to SJW’s share price at the time of California Water’s proposal. In light of SJW’s refusal to engage, and as part of its commitment to consummating a transaction with SJW, California Water has decided to take its proposal directly to SJW stockholders in the form of a tender offer.

“We strongly believe that our offer provides SJW stockholders with significantly greater value than the existing agreement with Connecticut Water, as well as immediate liquidity for their shares,” said Martin A. Kropelnicki, Chief Executive Officer and President of California Water. “By taking this step, we are reinforcing our commitment to a combination with SJW and are providing all SJW stockholders a voice in this process.”

The full terms, conditions and other details of the tender offer are set forth in the offering documents that California Water will file today with the Securities and Exchange Commission (SEC). The offer is being made on the terms and subject to the conditions set forth in the offer to purchase and letter of transmittal (together, the “Offer”), dated June 7, 2018, included in the Tender Offer Statement that will be filed with the SEC today. The Offer has no financing or due diligence conditions.

Stockholders with questions about the Offer or who need assistance in tendering their shares may call the Information Agent, Innisfree M&A Incorporated, toll-free at (888) 750-5834.  Banks and brokers may call collect at (212) 750-5833.

California Water also delivered today a letter to the Board of Directors of SJW requesting, among other things, that SJW cooperate with California Water to promptly deliver the necessary applications with the California and Texas Public Utility Commissions to commence the review process. A copy of the letter follows:

June 7, 2018

The Board of Directors

SJW Group

110 West Taylor Street

San Jose, CA 95110

Attention: Robert A. Van Valer, Lead Independent Director

Dear Mr. Van Valer:

Over two months ago on April 4, 2018, we delivered to you, the SJW Board, a private proposal to acquire 100% of the outstanding shares of SJW Group for $68.25 per share in cash.  As we have repeatedly conveyed to you, it is our belief that our proposal represents a “superior proposal” under the terms of your existing merger agreement with Connecticut Water.

We continue to be disappointed by your refusal to engage with us, and your decision on April 25 to commence a hostile public relations campaign against us and our stakeholders in response to our private proposal, and our attempts to negotiate with you in good faith.

The entrenching steps you have taken so far and stockholder money you’ve wasted are troubling in light of your May 31 announcement to amend your merger agreement with Connecticut Water to allow it to run a 45-day go-shop period, and actively solicit third party acquisition proposals. Notwithstanding your public statements highlighting the purported “merger of equals” nature of your transaction with Connecticut Water, the spirit of equality was not reflected in your decision not to demand a similar go-shop right that would have allowed you to seek, unrestrained, a better transaction for your stockholders.

In light of the foregoing, and the multiple attacks that you publicly and privately launched on the legitimacy of our proposal including referring to it as a “non-binding indication of interest,” we are left with no option but to take our proposal directly to SJW stockholders:  Today we commenced a $68.25 per share all-cash tender offer for all outstanding SJW shares.  Our binding offer is not subject to any financing or due diligence condition. Nor is our offer subject to negotiation of definitive transaction agreements with you.

As you might expect, our offer is conditioned on getting regulatory approvals from the California Public Utilities Commission and the Public Utility Commission of Texas.  Therefore, we hereby formally request that you and your advisors cooperate with us to promptly deliver the necessary applications with the PUCs to commence the review process. Our advisors are standing by to work with yours, and we are prepared to reimburse reasonable and customary third party expenses that you might incur in this regard.

Despite your unwillingness to engage with us, we continue to extend to you an invitation and proposal to engage and negotiate a transaction with us at a value of $68.25 per share.  We firmly believe that in the context of a negotiated transaction, we can together resolve any legitimate issues that you may have with our proposal.

It is our further belief that there is no legitimate contractual reason why you cannot immediately engage in discussions with us on the basis of our tender offer and the content of this letter. We look forward to your response, and the opportunity to work together to create value for our stockholders, customers, employees, and the communities we serve.

Sincerely,

Morgan Stanley is serving as financial advisor to California Water and Gibson Dunn is serving as its legal advisor. For additional information regarding California Water’s proposal to combine with SJW please visit www.sjwvalue.com.
