MIDDLESEX WATER COMPANY REPORTS

2014 FINANCIAL RESULTS

ISELIN, NJ, March 5, 2015 - Middlesex Water Company (“Middlesex” or the “Company”) (NASDAQ:MSEX) today reported financial results for the year ended December 31, 2014.

Highlights

2014 Operating Results

Consolidated operating revenues increased to $117.1 million for the year ended December 31, 2014, up from $114.8 million in 2013. The $2.3 million increase was primarily due to:

Operating and maintenance expenses for the year ended December 31, 2014 decreased $1.6 million or 2.7%, from 2013. This decrease reflects a $3.0 million reduction in employee benefit expenses, primarily due to lower postretirement plan costs resulting from improved performance in 2013 on our investment of retirement plan funds and a higher discount rate used for the actuarially determined 2014 expense; as well as lower weather related variable production costs of $0.4 million. Partially offsetting these decreases were increased repair and labor costs of $1.5 million related to severe winter weather in early 2014 and $0.3 million for all other expenses.

Earnings applicable to common stockholders for year ended December 31, 2014 were $18.3 million, or $1.13 per share on a fully diluted basis, compared to $16.4 million or $1.03 per diluted share in 2013.

Middlesex President and Chief Executive Officer Dennis W. Doll said, “As reflected in our 2014 results, Middlesex Water Company was able to successfully navigate the impact in 2014 of the loss of two significant customers in the prior year, as well as the challenges presented by unfavorable weather. We negotiated the favorable outcomes of rate proceedings in our Middlesex and Tidewater systems that went into effect in July and August, respectively. We also began full operation and ownership of the water production and distribution system of Dover Air Force Base. In addition, we continued our focus on managing expenses and worked to strengthen our core business of traditional regulated utility operations while capitalizing on our emerging expertise in the realm of non-regulated renewable energy and industrial treatment applications.”
