Middlesex Water Company (MSEX) Income Statement

Revenue growth of 10% to 14% across recent quarters suggests the trajectory is being driven by rate case outcomes and capital-driven rate base expansion rather than organic volume. Growth is uneven, however, with 2025Q4 and 2025Q3 showing flat-to-negative year-over-year revenue, which may indicate dependence on the timing of rate case approvals. Investors should monitor whether the next New Jersey filing sustains this pace.

The wide swing in operating margin, with the 2026Q3 peak sitting well above the 2024Q4 trough, suggests that earned returns are sensitive to when cost increases are recognized versus when rate relief takes effect. Net margin tracked the same pattern, implying the variability sits in regulated operations rather than below-the-line items. Narrowing of this spread would be a more constructive signal of regulatory alignment than any single strong quarter.

Rising depreciation alongside revenue growth suggests incremental capital is entering service, though the reported figures do not isolate CAPEX or CWIP balances. The PFAS remediation program could extend this pattern if costs are recovered through rate base treatment, which would convert a compliance burden into earnings growth. Whether that conversion occurs depends on regulatory treatment that the supplied data does not disclose.
