Creates Third Largest Investor-Owned Pure Water and Wastewater Utility Based on Rate Base in United States with Financial Strength, Geographic Diversity and Scale

Combined Company Positioned to Deliver Significant Benefits to Customers and Communities, Invest in Infrastructure and Create Sustainable Customer and Shareholder Value

San Jose, CA and Clinton, CT – October 9, 2019 – SJW Group (NYSE: SJW) (“SJW Group”) and Connecticut Water Service, Inc. (“Connecticut Water”) today announced the close of their merger. The combined company, SJW Group, is the third-largest investor-owned pure play water and wastewater utility based on rate base in the United States, serving nearly 1.5 million people across California, Connecticut, Maine and Texas. In connection with the closing of the transaction, Connecticut Water is now a wholly owned subsidiary of SJW Group, and Connecticut Water’s common shares have ceased trading on the NASDAQ stock exchange.

“As a leading national water and wastewater utility, we are well positioned to deliver significant benefits to all of our stakeholders, including shareholders, customers, employees and the local communities we serve,” said Eric W. Thornburg, Chairman, President and Chief Executive Officer of SJW Group. “This transformative combination provides us with the financial strength, geographic and regulatory diversity and increased scale that we believe will enable growth and create sustainable shareholder value. We will have greater capacity to invest in infrastructure, enhanced technical resources to provide high quality water and wastewater service to customers and communities and additional career growth opportunities for our employees. We will also continue to focus on local communities through corporate involvement and by supporting employee engagement.”

“This transaction brings together employees from two companies who share a passion for water and wastewater service, for being good corporate citizens and for preserving natural resources to sustainably serve current and future customers,” said David Benoit, President of Connecticut Water. “We will have the benefits of national scale while maintaining the experienced local leadership teams and employees to meet our customers’ needs. Our new team of 700+ local water professionals, led by a seasoned industry leadership team, is a powerful combination that will focus on serving customers and communities, driving long-term growth and delivering on our comprehensive set of commitments to all our stakeholders.”

Richard Knowlton, President of Maine Water, an operating subsidiary of Connecticut Water, added, “The team of professionals at Maine Water is excited to join SJW Group to realize the benefits of national scale while maintaining our local teams and focus on service. Our commitment to serve customers and communities in Maine is reinforced by the financial strength, geographic diversity and scale of the combined organization. This will allow us to continue to invest in Maine Water’s infrastructure to improve reliability and service of our water systems, support local communities, and help us deliver efficient systems, new technologies and share best practices to enhance service.”

SIGNIFICANT BENEFITS

The close of the transaction provides the following significant benefits:

•

A robust balance sheet that enhances SJW Group’s financial flexibility to increase sustained growth in its operating utilities’ rate bases, continue necessary investments in all of its water systems and create a stronger, more stable utility enterprise with greater diversification and continued strong operating cash flow and dividends;

•

An attractive, stable and higher earnings growth profile for the combined company, with expected high single-digit percentage earnings per share (EPS) accretion in 2021 after a neutral to slightly dilutive EPS impact in 2020 (excluding one-time transaction costs);

Enhanced service to customers and communities throughout the combined organization from the sharing of best practices, operational expertise and more extensive resources;

•

Continued commitments to environmental stewardship and sustainability, with an effort to further reduce the companies’ environmental footprint; and
