Unitil Corp
unitil.comUnitil Corp (NYSE: UTL) is a regulated utility holding company that distributes electricity and natural gas to approximately 215,100 customers across New Hampshire, Massachusetts, and Maine. Revenue comes primarily from state-regulated distribution rates charged to residential, commercial, and industrial customers, with gas operations generating $299.6 million in FY2025 (roughly 56% of total operating revenue) and electric operations contributing the remainder. Unitil operates through five wholly-owned distribution utilities: Unitil Energy (electric, New Hampshire), Fitchburg (electric and gas, Massachusetts), Northern Utilities (gas, New Hampshire and Maine), Bangor Natural Gas Company (gas, Maine, acquired January 31, 2025 for $71.4 million), and Maine Natural Gas Corporation (gas, Maine). The company also owns Granite State Gas Transmission, an interstate natural gas pipeline subsidiary. Regulated rates are set by the New Hampshire Public Utilities Commission, the Massachusetts Department of Public Utilities, and the Maine Public Utilities Commission, creating a cost-of-service model where allowed returns are determined by regulators rather than market competition. The business is capital-intensive and debt-reliant, consistent with regulated utility economics.
