Exhibit 99.1 SAN JOSE, CA, October 27, 2005 - SJW Corp. (AMEX:SJW) diluted earnings per common share for the quarter ended September 30, 2005 were $1.00, compared to $0.60 for the same quarter in 2004. The increase in net income is inclusive of the net of tax gain on sale of nonutility property of $1,095,000, or $0.12 per share, in September 2005. Operating revenue for the third quarter was $58,469,000 versus $52,297,000 for the same period in 2004, representing an increase of $6,172,000 or 12%. Revenues increased $6,328,000 due to cumulative rate increases and $292,000 due to new customers, which was partially offset by a decrease of $319,000 attributable to lower customer usage and a decrease in other revenues of $129,000. Water production costs for the third quarter of 2005 consisting of purchased water, power and pump taxes, decreased $101,000 from the third quarter of 2004. The decrease in production costs was primarily attributable to $333,000 decrease in usage and $594,000 as a result of greater availability of surface water. However, the decrease was partially offset by increases in the cost of purchased water and pump tax from Santa Clara Valley Water District of $742,000 and other costs of $84,000. Quarterly operating expenses for the third quarter of 2005, excluding water production costs and income taxes, increased $1,955,000 from 2004. The increase consisted principally of $849,000 in general and administrative costs, which includes a $356,000 increase in employee benefits' costs, $265,000 in professional services and $228,000 in salaries and other expenses. In addition, other operating expenses increased $593,000, taxes other than income increased $124,000 and depreciation expense increased $353,000 as a result of growth in utility plant. Income tax expense for the third quarter of 2005 was higher than the same period in 2004 due to increased pre-tax earnings. The increase in other comprehensive income of $2,375,000 was a result of the change in the market value of the investment in California Water Service Group. Year-to-date diluted earnings per common share were $1.91 compared to $1.32 for the same period in 2004. The increase in year-to-date earnings was primarily due to cumulative rate increases that were partially offset by the impact of lower customer demand. Year-to-date decrease in water production costs of $3,412,000 was primarily attributable to a decrease in usage and a greater availability of surface water and was partially offset by increases in the cost of purchased water and pump tax. Other non-water production costs increased $3,808,000 and the increase is largely attributable to an increase in general and administrative costs of $1,643,000 and an increase in depreciation expense of $1,139,000. The increase in year-to-date income taxes is due to increased pre-tax earnings. The year-to-date increase in other comprehensive income of $2,304,000 was a result of the change in the market value of the investment in California Water Service Group. At its meeting today, the Board of Directors of SJW Corp. declared a quarterly dividend on common stock of $0.2675 per share. The dividend is payable on December 1, 2005 to shareholders of record on November 7, 2005. SJW Corp. is a publicly traded holding company headquartered in San Jose, California.
