Middlesex Water Company (MSEX) is expected to drive future revenue growth over the next 2-3 years through a combination of strategic initiatives inherent to the utility sector.

1. Rate Increases and Adjustments: The company consistently seeks and obtains approvals for rate adjustments and increases. This includes Distribution System Improvement Charge (DSIC) applications in New Jersey, with a third such application expected to generate $1.9 million in annual revenues starting June 2025. Additionally, a recent petition to the New Jersey Board of Public Utilities (NJBPU) for new water rates aims to increase annual revenue by $24.9 million. The Tidewater system in Delaware also saw a temporary rate increase authorized, contributing $2.5 million annually.
2. Infrastructure Investments and Capital Programs: Middlesex Water is making substantial capital investments in its water and wastewater infrastructure to enhance service quality, improve system resiliency, and meet evolving regulatory compliance. The company invested $72 million in infrastructure during the first nine months of 2025 and plans for $93 million for the full year 2025. A larger capital program of $387 million is planned from 2025 through 2027. These investments bolster the company's rate base, forming the foundation for future rate recovery and revenue growth.
3. Customer Growth through Acquisitions and Organic Expansion: Middlesex Water is expanding its customer base through both organic growth and strategic acquisitions. The company completed the acquisition of Ocean View's water utility assets in Delaware, serving 900 customers, and has an agreement to acquire Pinewoods Acres water utility assets, also in Delaware. Furthermore, the Tidewater system in Delaware has experienced organic residential customer growth, reporting a 3.5% increase in 2024.
4. Growth in Non-Regulated Contract Services: While the regulated segment constitutes the majority of its business, the non-regulated sector also presents growth opportunities.
