Third Quarter Results

Net income for the three months ended September 30, 2025 was $7.0 million, a $0.1 million, or 2.2%, increase compared to net income for the three months ended September 30, 2024. Diluted net income per share increased 3.0% to $0.68, compared to $0.66 for the same period in 2024.

Revenues totaled $30.5 million for the three months ended September 30, 2025, $1.3 million, or 4.6%, more than revenues for the three months ended September 30, 2024.

Water sales revenue increased $0.7 million, or 3.1%, primarily the result of a temporary rate increase placed into effect on June 3, 2025, as permitted under Delaware law, until permanent rates are determined by the Delaware Public Service Commission, or DEPSC, as well as an increase in the number of customers served, partially offset by a slight decrease in consumption.

Other utility operating revenue increased approximately $0.4 million, or 12.6%, primarily due to an increase in wastewater revenue associated with additional customers served.

Non-utility operating revenue increased approximately $0.2 million, or 10.8%, primarily due to an increase in Service Line Protection Plan, or SLP Plan, revenue, resulting from an increase in rates placed into effect on December 1, 2024.

Operating expenses, excluding depreciation and income taxes, increased $1.0 million, or 6.7%, for the three months ended September 30, 2025, compared to the same period in 2024. Utility operating expenses increased $1.3 million, or 10.8%. The increase in utility operating expenses consists of a $0.7 million increase in payroll and employee benefit costs, a $0.4 million increase in supply and treatment costs, a $0.2 million increase in administrative costs, and a $0.1 million increase in transmission, distribution and collection system costs. The increase in utility operating expenses is partially offset by a $0.1 million decrease in purchased water costs.

Depreciation and amortization expense increased $0.2 million, or 6.4%, primarily due to additional depreciation from continued investment in utility plant related to providing supply, treatment, storage and distribution of water to customers and service to our wastewater customers.

Federal and state income tax expense increased $0.1 million, or 5.0%, primarily due to higher pre-tax book income.

Property and other taxes decreased $0.4 million, primarily due to a decrease in tax rates on utility plant partially offset by an increase in utility plant subject to taxation.

Other income increased $0.1 million, primarily due to an increase in allowance for funds used during construction, or AFUDC, as a result of higher long-term construction activity subject to AFUDC.
