SJW CORP. ANNOUNCES

SECOND QUARTER FINANCIAL RESULTS

SAN JOSE, CA, July 29, 2015 – SJW Corp. (NYSE: SJW) today reported financial results for the second quarter ended June 30, 2015. Operating revenue was $72.4 million in the quarter compared to $70.4 million in 2014. The $2 million increase in revenue was primarily attributable to $11.8 million in cumulative rate increases and $300,000 in revenue from new customers, offset by $9.3 million in lower customer water usage and a decrease in the net recognition of certain balancing and memorandum accounts of $800,000.

Water production expenses for the second quarter of 2015 were $26.8 million versus $33.1 million for the same period in 2014, a decrease of $6.3 million. The decrease in water production expenses was attributable to $7.4 million in lower customer water usage and $1.2 million in lower expenses due to an increase in the use of available surface water supply. These decreases were partially offset by $2.3 million in higher per unit costs for purchased water, groundwater extraction and energy charges. Operating expenses, excluding water production expenses, increased $3.2 million to $28.4 million from $25.2 million. The increase was due to $1.9 million in higher administrative and general expenses, $707,000 of higher depreciation expense, $315,000 in higher property taxes and other non-income taxes, and an increase of $271,000 in maintenance expenses. The increase in administrative and general expenses was primarily attributable to higher pension costs and costs related to the California General Rate Case proceeding and other activities.

Other expense and income in the second quarter of 2014 included a pre-tax gain on the sale of 125,969 shares of California Water Service Group stock of $2 million and a sale of a real estate investment property in Texas of approximately $300,000. No similar sales occurred in 2015.

The effective consolidated income tax rates were 37% and 31% for the quarters ended June 30, 2015 and 2014, respectively. The change in effective consolidated income tax rate was primarily due to a credit of $880,000 related to State of California enterprise zone sales and use tax credits in 2014.

Net income was $7.5 million for the quarter ended June 30, 2015, compared to $6.8 million for the same period in 2014. Diluted earnings per share were $0.36 and $0.34 for the quarters ended June 30, 2015 and 2014, respectively.

Year-to-date operating revenue increased by $9.5 million to $134.5 million from $125.0 million in the first six months of 2015. The increase was attributable to $20.8 million in cumulative rate increases, $700,000 in revenue from new customers and a net increase in the recognition of certain balancing and memorandum accounts of $1.2 million. These increases were offset by $13.2 million in lower customer water usage.

Year-to-date water production expenses decreased to $48.2 million from $56.6 million in 2014. The $8.4 million decrease was attributable to $8.9 million in lower customer water usage, $3.3 million in lower expenses due to an increase in the use of available surface water supply, offset by $3.8 million in higher per unit costs for purchased water, groundwater extraction and energy charges. Operating expenses, excluding water production costs, increased $6.2 million to $56.3 million from $50.1 million. The increase was due to $3.8 million of higher administrative and general expenses, $1.4 million of higher depreciation expenses, $606,000 in higher property taxes and other non-income taxes and $365,000 in higher maintenance expenses. The increase in administrative and general expenses was primarily attributable to higher pension costs and costs related to California General Rate Case proceeding and other activities.

Other expense and income in 2015 included interest on our Series L Senior Note which was funded in August 2014. Other expense and income in 2014 included a pre-tax gain on the sale of 125,969 shares of California Water Service Group stock of $2 million and a sale of real estate investment property in Texas of approximately $300,000. No similar sales occurred in 2015.

The effective consolidated income tax rates were 37% and 32% for the six-month periods ended June 30, 2015 and 2014, respectively. The change in effective consolidated income tax rate for the six-month period ended June 30, 2015 compared to the same period in 2014 was due to a credit of $880,000 related to State of California enterprise zone sales and use tax credits in 2014.

Year-to-date net income was $12.2 million, compared to $7.8 million in 2014. Diluted earnings per share were $0.59 in the first six months of 2015, compared to $0.38 per diluted share for the same period in 2014.

The Directors of SJW Corp. today declared a quarterly dividend on common stock of $0.195 per share. The dividend is payable on September 1, 2015 to shareholders of record on August 10, 2015.
