SJW CORP. ANNOUNCES

SECOND QUARTER FINANCIAL RESULTS

SAN JOSE, CA, July 31, 2013 – SJW Corp. (NYSE: SJW) today reported financial results for the second quarter ended June 30, 2013. Operating revenue was $74.2 million in the quarter compared to $65.6 million in 2012. The $8.6 million increase in revenue was primarily attributable to $5.3 million in higher customer water usage, $2.2 million in cumulative rate increases, recognition of certain balancing and memorandum accounts of $730,000, which management has determined are probable of future recovery and $362,000 in revenue from new customers.

Water production costs for the second quarter of 2013 were $32.5 million versus $27.4 million for the same period in 2012, an increase of $5.1 million. The increase in water production costs was primarily attributable to $2.3 million in higher customer water usage, $1.9 million in higher per unit costs for purchased water and groundwater extraction charges and $912,000 in higher costs due to a decrease in the availability of surface water supply. Operating expenses, excluding water production costs, increased $171,000 to $24.8 million from $24.6 million. The increase was due to $417,000 of higher depreciation expense, $300,000 in higher maintenance expenses and $115,000 in higher taxes other than income taxes, partially offset by a decrease in administrative and general expenses of $661,000 related to lower recycled water retrofit program expenses.

The effective consolidated income tax rates were 41% for the quarters ended June 30, 2013 and 2012.

Net income was $7.4 million for the quarter ended June 30, 2013, compared to $5.2 million for the same period in 2012. Diluted earnings per share were $0.37 for the quarter ended June 30, 2013, compared to $0.28 per diluted share for the same period in 2012.

Year-to-date operating revenue increased by $7.7 million to $124.4 million from $116.7 million in the first six months of 2013. The increase was primarily attributable to recognition of certain balancing and memorandum accounts of $2.6 million which management has determined are probable of future recovery, $2.5 million in cumulative rate increases, $2.0 million in higher customer water usage and $590,000 in revenue from new customers.

Year-to-date water production costs increased to $50.8 million from $47.5 million in 2012. The $3.3 million increase was primarily attributable to $2.9 million in higher per unit costs for purchased water and groundwater extraction charges and $1.4 million in higher customer water usage, partially offset by $1.0 million in lower costs due to an increase in the use of available surface water supply. Operating expenses, excluding water production costs, increased $2.0 million to $50.9 million from $48.9 million. The increase was due to $925,000 of higher depreciation expense, $511,000 in higher maintenance expenses, $285,000 of higher administrative and general expenses and $229,000 in higher taxes other than income taxes.

Other, net includes a pre-tax gain on the sale of a real estate investment property in Connecticut of approximately $1.1 million.

The effective consolidated income tax rates were 41% for the six-month periods ended June 30, 2013 and 2012.

Year-to-date net income was $8.8 million, compared to $6.3 million in 2012. Diluted earnings per share were $0.45 in the first six months of 2013, compared to $0.34 per diluted share for the same period in 2012.
