Exhibit 99.1 SJW CORP. ANNOUNCES 2010 ANNUAL AND FOURTH QUARTER FINANCIAL RESULTS (Dated: February 22, 2011) SAN JOSE, CA -- (BUSINESS WIRE) -- SJW Corp. (NYSE: SJW) today reported operating revenue for the year ended December 31, 2010 of $215.6 million versus $216.1 million for the year ended December 31, 2009, a decrease of $0.5 million. The decrease in revenue was primarily attributable to a decline in customer water usage of $5.5 million, partially offset by cumulative rate increases of $5.0 million. Net income was $24.4 million for the year ended December 31, 2010, compared to $15.2 million for the year ended December 31, 2009. Diluted earnings per common share for the year ended December 31, 2010 were $1.30, compared to $0.81 per share in 2009. The Company sold 907,392 shares of California Water Service Group stock during the year ended December 31, 2010, which contributed $0.60 per share to results. No sales of California Water Service Group stock occurred during the same period in 2009. Water production costs for the year ended December 31, 2010 were $76.6 million versus $83.5 million in 2009, a decrease of $6.9 million. The decline in water production costs is primarily attributable to $4.6 million in lower customer water usage and $3.0 million in savings due to greater surface water supply, offset by $0.7 million in higher per unit costs paid for power. Operating expenses, excluding water production costs and income taxes, for the year ended December 31, 2010 were $101.0 million versus $92.9 million for 2009, an increase of $8.1 million. This increase was primarily attributable to an impairment loss of $3.6 million in 2010 on a real estate investment in Tennessee, $2.7 million in higher depreciation and amortization, $2.4 million in administrative and general expenses largely related to higher benefit, salary and pension costs, and $0.9 million in other operating expenses, offset by a decrease of $0.9 million in maintenance expenses and $0.6 million in taxes other than income tax expense. Income tax expense decreased $1.3 million for the year ended December 31, 2010 to $9.0 million from $10.3 million for the year ended December 31, 2009 as a result of the tax benefit recognized on the impairment of our real estate investment. Total operating expense, including water production costs, for the year ended December 31, 2010 was $186.5 million, compared to total operating expense of $186.7 million in 2009. Fourth Quarter Financial Results - -------------------------------- Operating revenue for the fourth quarter ended December 31, 2010 was $50.8 million versus $48.6 million for the same period in 2009, an increase of $2.2 million. The increase was attributable to $1.2 million in cumulative rate increases, $0.6 million in higher customer water usage, $0.3 million in higher revenue from real estate operations and $97,000 from new customers. Net income was $8.1 million for the fourth quarter ended December 31, 2010, compared to $2.6 million for the same period in 2009. Diluted earnings per common share were $0.43 for the quarter ended December 31, 2010, compared to $0.14 per share for the same period in 2009. The Company sold 684,280 shares of California Water Service Group stock during the fourth quarter ended December 31, 2010, which contributed $0.46 per share to results. No sales of California Water Service Group stock occurred during the same period in 2009. Water production costs for the fourth quarter of 2010 were $18.0 million versus $17.4 million for the same period in 2009, an increase of $0.6 million. Higher customer water usage and decreased surface water supply contributed to the increase. Operating expenses, excluding water production costs and income taxes, for the fourth quarter of 2010 were $29.2 million versus $23.4 million for the same period in 2009, an increase of $5.8 million. This was attributable to increases of $3.6 million of impairment loss on a real estate investment in Tennessee, $1.4 million in administrative and general expenses, $617,000 in depreciation and amortization, $328,000 in other operating expenses, and $103,000 in taxes other than income tax expense, partially offset by a decrease of $208,000 in maintenance expenses. Income tax expense decreased $1.8 million for the fourth quarter in 2010 to a benefit of $321,000 from $1.5 million in expense for the same period in 2009 due to the tax benefit recognized on the real estate investment impairment loss. Total operating expense for the quarter ended December 31, 2010, was $47.0 million compared to $42.3 million in the period ended December 31, 2009. Other comprehensive loss in 2010 was $10.8 million and $8.2 million, net of tax, for the full year and fourth quarter of 2010, respectively, due to a change in the market value of the investment in California Water Service Group of $44,000 and the recognition of unrealized holding gains of $10.8 million that were reclassified out of accumulated other comprehensive income due to the sale of California Water Service Group stock.
