Middlesex Water Company REPORTS

FINANCIAL RESULTS for SECOND QUARTER

ISELIN, NJ, (August 2, 2012) Middlesex Water Company (NASDAQ:MSEX) (“Middlesex” or the “Company”) today reported operating revenues for the quarter ended June 30, 2012 of $27.4 million, up from $26.1 million for the same period in 2011. Net income increased $0.1 million to $3.7 million. Basic and diluted earnings per share were $0.23, remaining the same amount as in 2011. For the six months ended June 30, 2012, revenues were $50.9 million, as compared to $50.1 for the same period in 2011, and net income decreased to $5.4 million, from $6.2 million for the same period in 2011.

Second Quarter Operating Results

Operating revenues for the three months ended June 30, 2012 increased $1.3 million or 4.9%, from the same period in 2011, primarily due to increased sales of $0.8 million in our Delaware system, which includes Tidewater Utilities, Inc. (“Tidewater”), primarily due to the 10.49% interim rate increase that went into effect in November 2011 and increased connection fees. Revenues in the Company’s Middlesex system in New Jersey increased $0.1 million, reflecting increased commercial, industrial and residential customer demand for water as well as implementation of a purchased water adjustment clause in August 2011. Scheduled increases for our contract operations services led to additional revenue of $0.2 million.

Operation and maintenance expenses for the three months ended June 30, 2012 increased $0.7 million from the same period in 2011. This increase was primarily due to an additional $0.6 million in postretirement benefits plan expenses, primarily due to changes in actuarial assumptions in our retirement plans. Favorable weather conditions, and consequently fewer main breaks, contributed to a decrease in main repair costs of $0.1 million in the second quarter of 2012. Additionally, labor costs decreased $0.2 million, primarily due to higher capitalized payroll and less overtime resulting from fewer main breaks.

Middlesex Water Company Chairman, President and Chief Executive Officer Dennis W. Doll said, “We welcome increased demand by our customers for water and stand ready to meet peak demands for the remainder of the summer season. In addition, we are pleased with the timely approval by the Delaware Public Service Commission in June 2012 of a $3.9 million increase in base water rates for our Delaware subsidiary Tidewater; and the approval by the New Jersey Board of Public Utilities in July 2012 for a $8.1 million increase in base rates for Central New Jersey customers of our Middlesex system,” added Doll.

Six Month Operating Results

Consolidated operating revenues for the six months ended June 30, 2012 increased $0.8 million from the same period in 2011.  Revenues in our Delaware system increased $1.2 million, primarily due to interim rate increases and increased connection fees. Scheduled increases for our contract operations services led to additional revenue of $0.3 million. Revenues, however, from our Middlesex system customers were down $0.7 million, primarily due to lower demand. Operation and maintenance expenses increased $1.0 million from the same period in 2011. This was primarily attributable to increased employee benefits related costs.

For the six months ended June 30, 2012, basic and diluted earnings per share decreased to $0.35, as compared to $0.40 for the same period in 2011. Net income for the six months ended June 30, 2012 decreased $0.7 million from the same period in 2011.

Company Quarterly Dividend

The Company’s Board of Directors declared a quarterly cash dividend of $0.1850 per share, payable September 3, 2012 to common shareholders as of August 15, 2012. The Company has paid cash dividends in varying amounts continually since 1912 and has increased the dividend for 39 consecutive years.
