Cal Water Reports Third Quarter 2007 Results and Announces 252nd Consecutive Quarterly Dividend

SAN JOSE, Calif.--(BUSINESS WIRE)--

California Water Service Group (NYSE:CWT) today announced net income of $13.8 million and earnings per common share of $0.67 for the third quarter of 2007, compared to net income of $12.6 million and earnings of $0.68 per common share in the third quarter of 2006. Earnings per share decreased in the third quarter of 2007 by approximately $0.08 per common share on a diluted basis as a result of the equity offering completed in October 2006.

Revenues increased by $6.1 million, or 6%, to $113.9 million, compared to the same quarter of 2006, benefiting from a $5.1 million increase in rates, a $0.8 million increase in sales to new customers, and a $0.2 million increase in water sales to existing customers.

Total operating expenses for the third quarter of 2007 increased by $4.6 million, or 5%, to $96.3 million compared to the same quarter of 2006. Other operations expenses increased $2.7 million, or 12%, to $26.5 million compared to the same period last year. Contributing to this amount were increases in outside services, such as legal and consulting fees and employee benefit programs (medical and pension benefit costs).

Maintenance expenses were $4.2 million, unchanged from the same period last year. Depreciation expense increased $0.7 million, or 9%, to $8.4 million due to 2006 capital expenditures, compared to the third quarter of 2006. Taxes other than income taxes increased $0.2 million, or 7%, to $3.7 million. Total income taxes remained the same as last year and net other income increased approximately $0.3 million.

"Typically, our third quarter financial performance benefits from higher water sales due to the warmer weather, but this year we experienced milder summer weather throughout much of California. Customers also have heeded public calls for water conservation within the state and, as a result, we noticed very minor increases in demand by existing customers," said President and Chief Executive Officer Peter C. Nelson.

"Additionally, although we are currently collecting interim rates associated with our 2006 General Rate Case, they are below what we requested in the rate case proceeding before the Commission. The results of our 2006 GRC are pending final approval from the California Public Utilities Commission and, once approved, we will be able to collect the difference between the interim rates and the final rates approved," Nelson said.

Year-to-Date Results

For the nine months ended September 30, 2007, net income increased $4.0 million, or 21%, to $23.1 million, compared to $19.2 million for the same period in the previous year. Earnings per share increased $0.08, or 8%, to $1.11, compared to $1.03 for the same period in 2006. Revenues for the nine months increased $27.1 million, or 11%, to $281.2 million, compared to $254.1 million for the same period in the previous year. The equity offering completed in October 2006 decreased earnings per share by approximately $0.14 per common share on a diluted basis for the nine months ended September 30, 2007.

Nelson said that in the fourth quarter, the Company intends to remain focused on working with the Commission to implement the Water Action Plan and finalizing the 2006 General Rate Case.

"Going forward, we will continue to manage expenses, pursue strategic growth opportunities, and work on innovative regulatory solutions that benefit our stockholders, customers, and employees," he said.

At their meeting on October 24, 2007, the Directors of California Water Service Group declared the 252nd consecutive quarterly dividend on common stock. The quarterly dividend of $0.29 per share will be payable on November 16, 2007, to stockholders of record on November 5, 2007. The Board also declared a regular dividend on Series C preferred stock.
