Middlesex Water Company ANNOUNCES

SECOND QUARTER 2014 FINANCIAL RESULTS

ISELIN, NJ, (August 4, 2014) Middlesex Water Company (NASDAQ: MSEX) (“Middlesex” or the “Company”) today reported net income for the quarter ended June 30, 2014 of $4.7 million as compared to $4.5 million for the same period in 2013. Basic and diluted earnings per share for the quarter ended June 30, 2014 were $0.29, up from $0.28 in 2013. For the six months ended June 30, 2014, net income increased to $7.9 million as compared to $7.7 million for the same period in 2013.

Second Quarter Operating Results

Operating revenues for the three months ended June 30, 2014 increased $0.1 million to $29.2 million as compared to $29.1 million for the same period in 2013. In our Delaware system, which includes Tidewater Utilities, Inc. (“Tidewater”), revenues increased $0.6 million, primarily due to increased customer demand, increased fees for new water customer connections and the February 2014 6.5% interim base rate increase. Revenues from the Company’s Middlesex System in New Jersey decreased $0.7 million primarily due to the loss of the Borough of Sayreville as a wholesale customer in August 2013. Revenues from other systems increased $0.2 million.

Operating income for the three months ended June 30, 2014 increased $0.6 million from the same period in 2013, primarily due to lower employee benefit plan costs.

Middlesex Chairman, President and Chief Executive Officer Dennis W. Doll said, “While various factors impacted our operating revenues, we are pleased to report overall positive financial results as we continue to work to manage operating costs, make prudent investments in drinking water and wastewater infrastructure, grow our customer base and demonstrate technical expertise and industry leadership in the water and wastewater arena,” said Doll. “We are also pleased we were able to achieve a July 20, 2014 effective date relative to the recent settlement of our New Jersey rate case, in time to potentially add value in the 3^rd quarter. This is typically when water consumption in our regulated water utilities is at its highest,” added Doll.

Six Month Operating Results

Consolidated operating revenues for the six months ended June 30, 2014 increased $0.2 million to $56.4 million from the same period in 2013 primarily due to increased demand and an interim rate increase in our Tidewater System offset by decreased general metered service and contract sales in our Middlesex System.

For the six months ended June 30, 2014, basic and diluted earnings per share increased to $0.49, as compared to $0.48 and $0.47, respectively, for the same period in 2013.

Quarterly Dividend Declared

The Company’s Board of Directors declared a quarterly cash dividend of $0.19 per share, payable September 2, 2014 to common shareholders as of August 15, 2014.
