EXHIBIT 99.1 SJW CORP. (AMEX: SJW) ANNOUNCES FIRST QUARTER FINANCIAL RESULTS SAN JOSE, CA, April 28, 2005 - SJW Corp. (AMEX:SJW) basic earnings per common share for the quarter ended March 31, 2005 were $0.29, compared to $0.19 for the same quarter in 2004. Operating revenue for the first quarter was $33,306,000 versus $31,063,000 for the same period in 2004, representing an increase of $2,243,000 or 7%. Approximately $3,911,000 of the total revenue increase was primarily attributable to cumulative rate increases and $135,000 was due to new customers. The revenue increase was offset by $1,531,000 decrease due to lower customer demand and reduced parking revenue of $143,000 and a $129,000 decrease resulting from other sources. Total water production costs for the first quarter of 2005 consisting of purchased water, power and pump taxes, decreased $151,000, or 1% from the first quarter of 2004. The decrease was primarily attributable to reduced water production costs of $1,516,000 due to lower customer demand, partially offset by increases in the cost of purchased water and pump tax of $752,000, reduced surface water availability of $574,000 and higher energy prices of $39,000. Total quarterly operating expenses for the first quarter of 2005, excluding water production costs and income taxes, increased $823,000 or 3% from 2004. The increases consisted principally of: $166,000 in employee benefits costs, $138,000 in legal and accounting fees, $630,000 in depreciation expense on added utility plant, offset by decreases in business liability insurances of $108,000. Income tax expense for the first quarter of 2005 was higher than the same period of 2004 due to higher earnings. For the three months ended March 31, 2005, other comprehensive loss included $2,777,000 due to a decrease in the market value of the investment in California Water Service Group. The Directors of SJW Corp. today declared a quarterly dividend on common stock of $0.2675 per share. The dividend is payable on June 1, 2005 to shareholders of record on May 9, 2005.
