California Water Service Group Files Preliminary Proxy Materials to Urge SJW Group’s Stockholders to Vote Against Proposed Merger with Connecticut Water

Reaffirms Commitment to its All-Cash Proposal to Combine with SJW Group

SAN JOSE, Calif. — May 2, 2018 — California Water Service Group (NYSE: CWT) today announced it has filed preliminary proxy materials with the U.S. Securities and Exchange Commission to urge stockholders of SJW Group (NYSE: SJW) to vote against the proposed merger of SJW and Connecticut Water (NYSE: CTWS).

“We strongly believe our $68.25 per share all-cash proposal delivers superior value to SJW stockholders and is in the best interest of both companies’ stockholders,” said Martin A. Kropelnicki, President and CEO of California Water. “In our view, SJW’s stock merger with Connecticut Water forces SJW stockholders to forego substantial and immediate value for the promise of long-term accretion that may never materialize, due to the significant risk of operating a larger company with two separate systems that are 3,000 miles apart in different regulatory environments.”

Mr. Kropelnicki continued, “We believe the SJW Board would better serve its stockholders by immediately meeting with us to discuss our proposal, instead of continuing its emerging pattern of communication and governance practices that hurt their stockholders, employees, customers, and local communities. We stand ready to address directly with the SJW Board any legitimate issue it may have with our all-cash proposal.”

Absent engagement by the SJW Board, California Water will ensure that SJW stockholders have all of the facts and resources necessary to determine the best path forward for SJW. California Water is communicating closely with employees, customers, and local communities to outline the significant benefits the Company believes this common sense combination with California Water would provide. For more information on the many benefits of California Water’s proposal, please visit http://www.SJWValue.com.

In its preliminary proxy materials, California Water highlighted the benefits of its proposal for SJW stockholders, including the following:

·                  SJW stockholders would receive in our view superior and immediate economic value with California Water’s all-cash proposal, which exceeds SJW’s all-time high closing share price, represents a 30% premium to SJW’s closing stock price at the time of California Water’s April 4, 2018 proposal, and represents a 20% premium to SJW’s closing stock price on April 25, 2018, the day before the California Water proposal was announced.

·                  In our view, California Water offers a clear path to completing the transaction in a timely manner. California Water’s proposal is not subject to any financing contingency and the Company is confident it can move quickly to conduct due diligence, reach a definitive agreement, and obtain regulatory approvals.

California Water strongly believes that the SJW all-stock merger with Connecticut Water is clearly inferior for SJW stockholders. For example, in California Water’s opinion:

·                  If the Connecticut Water merger is completed, SJW stockholders would be forced to wait for uncertain benefits that, by SJW’s own admission, would not fully accrue until the long term, while bearing the substantial execution risks associated with operating two separate systems located 3,000 miles apart in different regulatory environments. In contrast, California Water’s proposed transaction offers substantial and certain value to SJW stockholders.

·                  SJW would be led by a Board and CEO who are largely unfamiliar with the San Jose community and the unique challenges of running a California-based water utility. Six out of 12 directors for the new SJW/Connecticut Water Board would come from Connecticut Water — five are current Connecticut Water directors and the sixth is SJW’s brand new Chairman and CEO, Eric Thornburg, who ran Connecticut Water for more than 11 years, until late last year.

·                  The completion of the Connecticut Water transaction is uncertain given Eversource Energy’s pending bid for Connecticut Water and the need for a 2/3 vote of Connecticut Water shareholders.

·                  The SJW/Connecticut Water transaction faces regulatory approval in the same number of jurisdictions as the California Water proposal. SJW has cited regulatory approval as a reason for rejecting the California Water proposal; however, it then acknowledges the Connecticut Water transaction also requires regulatory approval in two different states — Connecticut and Maine. Regulators in these states have no existing relationships with SJW and may well have concerns approving a transaction in which the acquiring company is located in California 3,000 miles away.

In its preliminary proxy materials, California Water urges SJW stockholders to vote against the Connecticut Water merger by:

·                  Voting “AGAINST” the proposal to approve the issuance of shares of SJW common stock to Connecticut Water shareholders pursuant to the merger;

·                  Voting “AGAINST” the proposal to adopt the SJW certificate of incorporation amendment; and

·                  Voting “AGAINST” the proposal to approve any motion to adjourn the SJW special meeting.

California Water remains fully committed to its proposed combination with SJW, with the goal of working collaboratively with SJW to reach an agreement.

Dear Colleagues,

I wanted to update you on an important step we have taken as part of our effort to combine with SJW Group.

Today we filed preliminary proxy materials with the U.S. Securities and Exchange Commission to urge SJW stockholders to vote against the proposed merger of SJW Group and Connecticut Water.  SJW’s stockholders have the final say on SJW’s agreement with Connecticut Water.  We are encouraging SJW stockholders to vote against that transaction and send a message to SJW’s Board of Directors that they should meet with us and seriously consider our proposal.

There are several more procedural steps that need to occur before SJW stockholders vote on the merger, but today’s filing is an important signal that we remain fully committed to completing this common sense combination with SJW.  For more detail on our filing, a copy of the press release we issued today can be found here: http://www.SJWValue.com.

Given SJW’s unwillingness to engage with us, it’s not surprising that misinformation and rumors have started to circulate. I want to make several points clear about our proposed combination with SJW:

·                  There will be NO employee lay-offs below the executive level at either company as a result of this combination.  We believe employees of both companies would benefit from greater opportunities by working for a larger California-based water utility, sharing best-in-class work processes, technology, and resources between the two companies.  California Water is widely recognized as one of the industry’s leading employers, and we look forward to building on that track record following this combination.

·                  We believe customers would receive benefits from cost savings and better service through increased operational efficiencies, additional resources, award-winning customer service, and leading-edge information technology systems.

·                  In our view, more local communities would benefit from California Water’s track record of actively supporting the communities in which it operates.

We remain as confident as ever in the merits of this combination, which would create a larger and stronger California-based water utility better positioned to anticipate and meet the needs of our combined three million people served — including approximately 1.4 million people in the Bay Area.

We are in the early stages of this process, so we appreciate your efforts to stay focused on the business at hand every day as we continue to deliver the reliable and high quality service our customers expect. We have asked every district manager and department head to conduct a brief huddle to discuss the preliminary proxy filing.

As the solicitation of proxies is regulated by SEC rules, related communications need to be coordinated.  If you are contacted by the media, elected officials, or other external stakeholders, please redirect those inquiries to Shannon Dean (sdean@calwater.com), Paul Townsley (ptownsley@calwater.com), or Tom Smegal (tsmegal@calwater.com).

Thank you for your continued dedication to Cal Water.

Sincerely,

Martin A. Kropelnicki

President and Chief Executive Officer

California Water Service Group Confirms Proposal to Acquire SJW Group for $68.25 Per Share in Cash

Proposal exceeds SJW’s all-time high closing price and represents 20% current premium

Combination would create a larger and stronger California-based utility, providing substantial benefits for customers, employees, and local communities

California Water’s proposal delivers superior value to SJW stockholders and other constituencies compared to proposed SJW/Connecticut Water Service all-stock merger

SAN JOSE, Calif. — April 26, 2018 — California Water Service Group (NYSE: CWT) today confirmed that it proposes to acquire SJW Group (NYSE: SJW) for $68.25 per share in an all-cash transaction valued at approximately $1.9 billion including assumption of debt.  California Water’s proposal, which exceeds SJW’s all-time high closing share price, represented a 30% premium to SJW’s share price at the time of California Water’s April 4, 2018 proposal, and represents a 20% premium to SJW’s closing stock price yesterday, was reiterated today in a letter to SJW’s Board of Directors (see below).  California Water is confident of its ability to obtain timely regulatory approval and to finance the transaction.

Martin A. Kropelnicki, President and CEO of California Water, said: “We have repeatedly sought to discuss privately our superior proposal with SJW’s Board, but SJW has refused to engage and just informed us last night that the SJW Board rejected it on April 13, 2018.  Their lack of engagement has prevented their stockholders from learning about the substantial and immediate value we can deliver.  We are now making our proposal public so stockholders can evaluate it for themselves.  We are confident they will view it as clearly superior to the Connecticut Water transaction and to SJW’s standalone prospects.”

Strategic and financial benefits of a transaction include:

·                  Superior value to SJW’s pending all-stock merger with Connecticut Water.  California Water’s proposal would provide SJW stockholders with substantial and certain near-term value greater than SJW’s proposed all-stock merger with Connecticut Water given the current premium to SJW’s stock price.

·                  The creation of a larger and stronger California-based water utility.  SJW would be a superb strategic and operational fit that would enhance California Water’s position as the country’s third-largest regulated water utility, with a rate base of $1.9 billion.  The company would be better positioned to anticipate and meet the needs of the more than 3,000,000 people it would serve in California, Washington, New Mexico, Hawaii, and Texas, including approximately 1.4 million people in the greater Bay Area.  It would also have greater ability to invest in employees and offer broader career opportunities, as well as actively support the communities served.

·                  Firm commitments to deliver significant value to California customers through this transaction, including sharing the benefits in ways partners without a local presence cannot.  The transaction is expected to result in meaningful cost savings, which will be shared with customers.  Working together, we are confident that customers would benefit from increased efficiencies and sharing of resources, our award-winning customer service programs, and leading-edge information technology systems.

·                  The ability to invest in critical infrastructure projects.  Combining the two companies would enable continued investment in key projects needed to ensure a reliable water supply that meets increasingly stringent water quality standards.  California Water is committed to maintaining both companies’ capital expenditure programs and would expect to increase investments post-transaction.

·                  Intimate familiarity with SJW and its operations.  Since California Water is headquartered in San Jose, as is SJW, California Water is intimately familiar with the community, its priorities, and its decision-makers.  We also have deep insight into many of the operational, water supply, water quality, and environmental sensitivities of SJW’s system.  This knowledge of SJW’s operations and adjoining service territories would also enable us to seamlessly integrate and efficiently operate the combined system.

April 26, 2018

Robert A. Van Valer

Lead Independent Director

SJW Group

110 West Taylor Street

San Jose, CA 95110

CC: Eric W. Thornburg, Chief Executive Officer and President; Daniel B. More, Board Member

Dear Mr. Van Valer:

We are writing to reiterate our $68.25 all cash proposal to acquire 100% of the outstanding shares of SJW Group (“SJW”).  As you know, we have had a long-standing interest in combining SJW with California Water Service Group (“Cal Water”), and have reached out to your Board of Directors numerous times over many years, most recently in letters dated September 18, 2017, April 4, 2018 and April 17, 2018.  We have expressed our strong desire to hold private discussions with SJW, and we remain deeply disappointed that you and your Board have not engaged.  At this point, you have left us with no choice but to make our proposal public, so your stockholders can evaluate it.  We are confident they will view our proposal as clearly superior to the Connecticut Water transaction and to your standalone prospects.

Our compelling all-cash offer of $68.25 exceeds SJW’s all-time high closing share price, represented a 30% premium to SJW’s share price at the time of our April 4, 2018 proposal, and provides your stockholders with a 20% current premium.  We are confident in our ability to finance this transaction and there would be no financing condition in our proposal.  We have previously provided a Highly Confident Letter from our financial advisor, Morgan Stanley, for the full amount of the transaction.  Further, based on consultation with our counsel, Gibson Dunn & Crutcher LLP, we are prepared to enter into a merger agreement on terms consistent with those of your merger agreement with Connecticut Water, adjusted to reflect the all-cash nature of our proposal.  Based on our strong track record of operating in California, we are confident in our ability to obtain regulatory approval of the transaction on a timely basis.

Unlike the Connecticut Water transaction, our proposed transaction offers substantial and certain value to SJW stockholders.  In the Connecticut Water transaction, your stockholders would have to wait for uncertain benefits that, by your own admission, would accrue over the long term, while bearing the substantial execution risks associated with operating in two separate businesses located 3,000 miles apart in different regulatory environments.  Why should your stockholders forego superior certain value based on your promises of long-term accretion that may never materialize?

The combination of SJW and Cal Water is supported by a compelling strategic rationale.  The acquisition would create a larger and stronger California-based water utility that would be better able to anticipate and meet the needs of the 3,000,000 people our companies serve in the Western U.S., including approximately 1.4 million people in the greater Bay Area.  Since both companies are headquartered in San Jose, CA, we are already intimately familiar with the community, its priorities, and its decision-makers.  We also have deep insight into many of the operational, water supply, water quality, and environmental sensitivities of SJW’s system.  Our familiarity with SJW’s operations and our adjoining service territories would enable us to seamlessly integrate and efficiently operate the combined system.  Furthermore, our enhanced economies of scale will enable us to continue to invest efficiently in infrastructure needed to ensure a reliable water supply that meets increasingly stringent water quality standards.

In addition, we firmly believe our proposal offers substantially greater benefits to customers, employees and the communities we collectively serve than the Connecticut Water transaction, and these benefits support our belief in our ability to achieve timely regulatory approval.

·                  Customer Benefits & Cost Savings: We are prepared to make firm commitments to deliver significant value to California customers, including sharing the benefits we receive in ways that partners without a strong local presence cannot.  We expect the transaction to result in meaningful cost savings which we can share with customers.  We believe our combined customer base will receive better service through increased operational efficiencies, additional resources, award-winning customer service, and leading-edge information technology systems.

·                  Commitment to Employees: Combining SJW and Cal Water would lead to greater opportunities for employees.  Operations and customer service personnel would benefit from more opportunities and resources to enhance their careers by working for a larger California-based water utility.  We share the same union and would honor all of SJW’s existing collective bargaining agreements.  We would not reduce the combined company’s union-represented front line operations or customer service personnel.  We do not anticipate any significant changes to employee compensation or benefits.

·                  Serving Our Local Communities: Cal Water actively supports our communities.  We have a proven track record of working successfully with the California PUC and community leaders.  In 2017, we donated to over 320 local community organizations.  SJW customers would benefit from our continued emphasis on improving the quality of life in our communities.

·                  Environmental Stewardship: Improving water quality and environmental stewardship are key pillars of Cal Water’s strategy.  Our industry-leading efforts, combined with increased size and scale, will enable us to bolster key programs such as conservation, affordability, sustainability, environmental protection, and assistance to neighboring disadvantaged communities that do not have access to safe and reliable water.

We are committed to pursuing this transaction.  We have sought for many years to work with you on a business combination on a friendly, constructive and private basis.  We have been consistently rebuffed and thus have no option but to make our compelling proposal public.  We are convinced that the substantial benefits of this transaction for stockholders and other constituencies merit an open-minded evaluation by the SJW Board of Directors who will now have the ability to consider feedback from stockholders and others.

We stand ready to engage, and have the resources internally and externally to move expeditiously toward completing confirmatory due diligence and finalizing definitive agreements.  We would appreciate your timely response.
