Material Changes and Drivers
- Revenue Growth: Total operating revenue increased 8.3% to $536.0 million. Gas operating revenue rose 21.5% to $299.6 million, driven by the inclusion of Bangor and Maine Natural, higher rates, customer growth, and colder winter weather. Electric operating revenue decreased 4.8% to $236.4 million, primarily due to lower pass-through costs of electric sales as more customers purchased supply from third parties, partially offset by higher distribution rates.
- Profitability: GAAP Net Income increased 6.6%. Adjusted Net Income (excluding transaction costs) increased 11.5%. Gas Adjusted Gross Margin increased 19.3% to $199.1 million, while Electric Adjusted Gross Margin increased 6.8% to $114.6 million.
- Expenses: Operation and Maintenance (O&M) expenses increased 19.2% to $92.5 million due to higher utility operating costs, labor costs, and acquisition-related costs. Depreciation and Amortization increased 16.6% to $88.7 million, reflecting higher utility plant in service and recent rate case adjustments.
- Acquisitions: The acquisitions of Bangor and Maine Natural contributed $36.2 million to gas operating revenue and $16.6 million to Gas Adjusted Gross Margin in 2025.
Guidance, Outlook, and Risks
- Dividend: The Board declared a quarterly dividend of $0.475 per share in January 2026, an increase of $0.025, resulting in an annualized rate of $1.90 per share (up from $1.80 in 2025).
- Capital Spending: Projected capital spending for 2026 is $221 million.
- Outlook: Management expects continued growth driven by rate increases, customer growth, and infrastructure investments. The company is pursuing the acquisition of the Aquarion water companies, subject to regulatory approval.
- Risks:
- Regulatory: Changes in rate-making, cost recovery mechanisms, and environmental regulations (including climate change mandates) could impact financial results.
- Weather: Results are seasonal; mild winters or summers can decrease sales volumes, though revenue decoupling mitigates some volume risk in NH and MA.
- Financing: Rising interest rates increase borrowing costs for variable-rate debt and new issuances.
- Cybersecurity: Operational risks related to cyber-attacks and infrastructure failures.
Investor Verification Checklist
- Acquisition Integration: Verify the financial performance and integration progress of Bangor Natural Gas and Maine Natural Gas Corporation.
- Regulatory Approvals: Monitor the status of the pending Aquarion Water Companies acquisition and the outcome of the Massachusetts Supreme Judicial Court appeal regarding the $1.4 million negative excess ADIT recovery.
- Rate Case Outcomes: Track the resolution of the Unitil Energy base rate case filed in May 2025 and the Fitchburg performance-based ratemaking adjustments.
- Debt Covenants: Confirm continued compliance with the Credit Facility covenant requiring Funded Debt to Capitalization not to exceed 65%.
- Weather Normalization: Assess the impact of weather-normalized sales versus actual sales, particularly for the non-decoupled gas service areas in Maine.
