Middlesex Water Company Reports First Quarter 2026 Earnings

•Diluted earnings per share (“EPS”) of $0.57

•Invested $21 million in water and wastewater utility infrastructure during the three months ended March 31, 2026

•Declared $0.36 common stock cash dividend

ISELIN, N.J., April 30, 2026 -- Middlesex Water Company (“Middlesex” or the “Company”) (NASDAQ: MSEX) today announced financial results for the first quarter ended March 31, 2026.

“Our first-quarter results reflect disciplined execution across our operations, capital program, and regulatory strategy,” said Nadine Leslie, Chair, President and Chief Executive Officer of Middlesex Water Company. “We remain focused on delivering reliable service, investing strategically for long-term growth, and advancing our MWC 2030 Vision. This performance underscores the strength of our fundamentals and the dedication of our employees in driving consistent operational and financial outcomes.”

First Quarter 2026 Results

Middlesex reported net income of $10.6 million and diluted EPS of $0.57, compared to net income of $9.5 million and diluted EPS of $0.53 for the same quarter in 2025.

Operating revenues for the quarter ended March 31, 2026, were $48.7 million, an increase of $4.4 million, compared to $44.3 million for the same quarter last year. Operating revenues increased $3.4 million in the Middlesex System due to increased wholesale demand, customer consumption and base rate increases and $0.8 million in the Tidewater System primarily attributable to increased customer consumption, customer growth and rate increases. Non-regulated and other operating revenues increased $0.2 million, primarily due to higher supplemental contract services.

Operating expenses for the quarter ended March 31, 2026, were $35.6 million, an increase of approximately $2.9 million, compared to $32.7 million for the same quarter last year. The increase is primarily driven by increased variable production costs from higher production resulting from increased customer demand, higher labor cost due to wage and employee headcount increases partially offset by higher capitalizable costs.

Selective and Sustainable Growth

Middlesex invested approximately $21 million to upgrade, replace and enhance the resiliency of its water and wastewater utility infrastructure during the three months ended March 31, 2026, or approximately 17% of its planned 2026 annual investment of $126 million.

Annual Meeting and Dividend Declared

Middlesex will hold its Annual Meeting on Tuesday, May 19, 2026, at 11:00 a.m. EDT. Shareholders may obtain instructions to access the meeting by visiting www.virtualshareholdermeeting.com/MSEX2026 and entering the 16-digit control number listed on their Notice of Internet Availability of Proxy Materials or proxy card.

As previously announced on April 24, 2026, the Company’s Board of Directors declared a second quarter cash dividend of $0.36 per common share. Dividends on common shares will be paid on June 1, 2026, to shareholders of record as of May 15, 2026. Middlesex has paid cash dividends each year since 1912 and has increased the dividends received by shareholders each calendar year for 53 consecutive years.
