Company overview

MIDDLESEX WATER CO

Middlesex Water Co. operates as a regulated public utility focused on delivering safe drinking water and wastewater services within its legacy SIC 4941 water supply framework, catering to a mix of suburban residential communities, municipal partners, and regional commercial customers who rely on its treatment plants, distribution networks, and customer service support to meet everyday and emergency demand. The company’s business model leans on long-term contracts and rate cases before state utility commissions, tying revenue growth to capital investments and compliance milestones; this regulatory oversight also defines the material risk landscape, exposing Middlesex to potential rate-volume mismatches, infrastructure replacement costs, and evolving environmental standards that can delay approvals or amplify operating expenses. Operating under ticker MSEX and noted as CIK 66004, the latest SEC filing details are currently unknown, yet its utility-centric holdings and governance routines underscore the importance of monitoring updates—view live SEC filings on Earnings Feed.
