Dear Fellow Connecticut Water Shareholder:
I am writing to you at a critical time in your company’s history and to ask you to help protect Connecticut Water and the future of our company and its long record of superior customer service by disregarding the aggressive takeover attempts by the state’s largest electric company and trusting Connecticut Water and our 60 plus years of performance for our customers and shareholders.
Ensuring that your company is best positioned for sustainable growth while also serving our mission as a public water utility has long been a priority for the Connecticut Water Board of Directors and management team. That is reflected in our consistent record of delivering superior value to shareholders and superior service to customers:
 
✓	Connecticut Water has delivered a 179% total shareholder return over the past five years, outperforming peers and the Dow Jones Utility Average Index by 66% and 145%, respectively.	
✓	Connecticut Water has customer satisfaction rankings that consistently exceed 90% across all key areas, including service, water quality, capabilities, emergency response times, corporate citizenship and value.	
As part of our commitment to serving your best interests, on March 15, we announced a merger of equals with SJW Group (“SJW”) that we believe will enable us to continue our record of value creation – for shareholders, customers, employees and the communities we serve – well into the future. Like Connecticut Water, SJW has a passion for providing life-sustaining water service to families and communities, protecting and preserving the environment, and creating value through prudent capital investments. Together, we will be the 3 rd largest water utility in the nation with a presence across 4 states. Our increased scale and diversification will create a new pure-play water company with substantial value and growth opportunities – at close and over the long-term.
The benefits of our merger with SJW are exciting, and have drawn the attention of Eversource Energy who is attempting to derail our merger through an unsolicited, hostile acquisition campaign to obtain this value for its own . As part of its campaign, Eversource has:
 
•	 	Submitted an inferior acquisition proposal that delivers less value to Connecticut Water shareholders than provided by the SJW merger;	
•	 	Made no commitment to Connecticut Water employees or jobs . Eversource’s past transaction resulted in significant layoffs. Growth is the focus of the CTWS merger with SJW and we expect no job cuts;	
•	 	Failed to address or indicate any desire to improve its dismal record of customer service , which is among the worst in the nation; and	
•	 	Dismissed the concerns of independent industry analysts who have publicly questioned the merits of Eversource’s unsolicited hostile campaign and Eversource’s ability to grow.	
Notwithstanding Eversource’s actions, we remain committed to the SJW merger and are encouraged by the strong support we have received from numerous stakeholders, including shareholders, employees and customers. Your support is also very important and you can help by sharing this information with others in your community.
Later this year, a Special Meeting of Shareholders will be held to approve the merger of CTWS with SJW, and we will need your support. Details for this meeting and instructions on how you can vote using the Company’s GREEN proxy card will be mailed to shareholders in the coming weeks.
Connecticut Water shareholders have long been strong partners with our company, and we thank you in advance for your continued support. We are here to answer any questions and will continue to keep you informed.
On behalf of the Connecticut Water Board of Directors,

President and Chief Executive Officer
