CALIFORNIA WATER SERVICE GROUP

We believe our employees are our most valuable asset and are critical to our continued success. We focus our attention on attracting and retaining talented and experienced individuals to manage and support our operations. We offer our employees a broad range of Company-paid benefits, and we believe our compensation package and benefits are competitive with others in our industry. Additional information about our employee benefit plans is included in Note 11 of the Notes to Consolidated Financial Statements.

We are committed to hiring, developing, and supporting a diverse and inclusive workplace. Our employees are expected to exhibit and promote honest, ethical, and respectful conduct. All of our employees must adhere to a business code of conduct that sets standards for appropriate behavior and ethics and includes required internal training on preventing, identifying, reporting, and stopping any type of discrimination.

Employee health and safety in the workplace is one of the Company's core values. Safety efforts are led by the Executive Safety Committee and supported by safety committees that operate at the local level. Hazards in the workplace are actively identified and management tracks incidents so remedial actions can be taken to improve workplace safety.

As evidenced by our internally created Future Leaders of Water Development Program, our management team supports a culture of developing future leaders from our existing workforce, enabling us to promote from within for many leadership positions. We believe this provides long-term focus and continuity to our operations while also providing opportunities for the growth and advancement of our employees. Our focus on retention is evident in the length of service of our management team. The average tenure of our management team is over 10 years.

Employee levels are managed to align with the pace of business and management believes it has sufficient human capital to operate its business successfully. Management believes that the Company's employee relations are favorable. At December 31, 2023, we had 1,266 employees, including 1,118 at Cal Water, 82 at Washington Water, 48 at Hawaii Water, 18 at New Mexico Water, and no employees at Texas Water. In California, the Utility Workers Union of America (UWUA), AFL-CIO represents our non-exempt field, customer service, and non-confidential clerical employees and the International Federation of Professional and Technical Engineers (IFPTE), AFL-CIO represents our professional and technical engineering and water quality laboratory employees.

As of December 31, 2023, we had 667 employees represented by the UWUA and 90 employees represented by the IFPTE. In 2021, we reached a six-year agreement with both unions on a new contract that runs from May 14, 2021 (UWUA) and October 4, 2021 (IFPTE) through February 28, 2027. We believe this agreement continues to provide our employees with a market competitive pay and benefits package.

Employees at Hawaii Water, Washington Water, and New Mexico Water are not represented by a labor union.
