Unitil Corporation issued and sold $27 million of 5.42% Senior Unsecured Notes, Series 2026A, due September 24, 2031, and $33 million of 5.79% Senior Unsecured Notes, Series 2026B, due September 24, 2036. The notes were issued under a note purchase agreement entered into September 24, 2026.
Unitil plans to use the net proceeds for capital contributions to its utility subsidiaries, refinancing existing debt and general corporate purposes. The notes were offered principally to institutional investors under the Securities Act Section 4(a)(2) exemption. They are unregistered and may not be offered or sold in the United States absent registration or an applicable exemption.
Unitil Corporation completed its acquisition of Aquarion Water Company of New Hampshire, Inc. and Abenaki Water Co., Inc. for a purchase price of $55.8 million, including the assumption of approximately $13.7 million of debt plus about $0.6 million for estimated working capital and reimbursable capital expenditures. The acquired water systems have an estimated $47.0 million rate base as of December 31, 2025 and serve roughly 11,000 customers across eight New Hampshire communities, bringing Unitil’s total customer count to about 226,100 across New Hampshire, Maine and Massachusetts.
To support this and prior acquisitions, Unitil entered into an Amended and Restated Credit Agreement with The Bank of Nova Scotia, providing an $86.0 million Tranche A loan tied to its Maine Natural Gas Corporation acquisition and a $50.0 million Tranche B loan for the AWC-NH and Abenaki acquisition. Unitil borrowed $86.0 million on October 31, 2025 for Maine Natural Gas Corporation and $42.7 million on June 30, 2026 for the Aquarion companies, with a maximum Funded Debt to Capitalization covenant of 65%.
Unitil also entered into an Operating and Transition Services Agreement under which Aquarion Water Authority and affiliates will provide services for up to 60 months to AWC-NH, Abenaki and AWC-MA, with costs reimbursed at actual cost plus a 5% margin. The company states the Aquarion acquisition is expected to be earnings accretive over the long term and to support its long-term earnings per share growth target of 5%–7%.
Unitil Corporation has amended its agreement to acquire three regulated water utilities from Aquarion Water Authority and its affiliate RWA. The deal covers all shares of Aquarion Water Company of Massachusetts, Aquarion Water Company of New Hampshire, and Abenaki Water Co.
Under Amendment No. 3, the contractual “Termination Date” for completing or ending the transaction is extended to June 30, 2026, replacing the prior date of May 25, 2026. All other terms of the original Purchase and Sale Agreement and prior amendments remain unchanged.
Unitil Corporation released an investor presentation for the AGA Financial Forum outlining its regulated utility growth strategy and recent progress. The company highlights record net income of $50.2 million and adjusted EPS of $3.16, supported by a growing customer base in Maine, Massachusetts and New Hampshire. It reports a five-year utility capital investment plan of $1.2 billion, which is expected to drive long-term rate base growth of 6.5%–8.5% and annual EPS growth of 5%–7%. Recent acquisitions in Maine and the pending Aquarion water acquisition are positioned to add gas and water customers, expand rate base and support a targeted total shareholder return of 8%–10%, while maintaining investment-grade credit metrics.
Unitil Corporation’s subsidiary Fitchburg Gas and Electric Light Company entered into a Note Purchase Agreement to issue two new long-term debt tranches. Fitchburg sold $23,000,000 of 5.62% Senior Unsecured Notes, Series 2026A, due April 30, 2036 and $17,000,000 of 5.87% Senior Unsecured Notes, Series 2026B, due April 30, 2041 to institutional investors including State Farm entities and CoBank.
The notes include customary covenants and events of default and may become immediately due if a default occurs. Fitchburg plans to use the net proceeds to refinance existing consolidated Company debt and/or for general corporate purposes. The notes were offered in a private placement under Section 4(a)(2) of the Securities Act and are not registered for public sale.
Unitil Corporation reported the results of its Annual Meeting of Shareholders held on April 29, 2026. Of 17,986,069 common shares entitled to vote, 15,944,668 shares, or 88.65%, were represented, establishing a quorum.
Shareholders elected Class II directors Neveen F. Awad, Winfield S. Brown, and Mark H. Collin. They also ratified Deloitte & Touche LLP as independent registered public accounting firm for 2026 and approved, on an advisory basis, compensation for the Company’s Named Executive Officers.
Unitil Corporation used its shareholder meeting presentation to highlight record net income of $50.2 million and adjusted EPS of $3.16, along with a $1.90 annualized dividend, reflecting its regulated utility growth strategy.
The company serves about 110,100 electric and 105,000 natural gas customers across Maine, Massachusetts, and New Hampshire, and targets long-term EPS growth of 5.0%–7.0%, rate base growth of 6.5%–8.5%, and total shareholder return of 8.0%–10.0%. A five-year utility capital plan of approximately $1.2 billion focuses on grid modernization, resiliency, and natural gas infrastructure. Recent acquisitions of Bangor Natural Gas and Maine Natural Gas, plus a pending purchase of three Aquarion water companies, are expected to add rate base, natural gas customers, and about 23,000 water customers.
Unitil reports consolidated rate base of $1,329 million for 2025 and maintains FFO/debt of 16.3%, above downgrade thresholds. A 5 MW Kingston solar facility generating 9.7 million kWh annually and providing an estimated $2 million in customer savings illustrates its renewable investments.
Unitil Corporation updated two key agreements tied to its growth plans. The company amended its existing at-the-market equity program, under which it may sell up to $50 million of common stock, replacing Janney Montgomery Scott LLC with Huntington Securities, Inc. as an agent and forward purchaser alongside Scotia Capital (USA) Inc. and The Bank of Nova Scotia.
Separately, Unitil further amended its purchase agreement to acquire Aquarion’s Massachusetts and New Hampshire water companies and Abenaki Water Co., extending the transaction’s contractual termination date to May 25, 2026 while leaving other terms unchanged.
Unitil Corporation updated its equity compensation program and granted new stock awards to senior executives. The revised practices continue annual grants of time-vesting and performance-vesting restricted shares, but dividends on both types will generally be retained by the company and paid only if the shares ultimately vest.
Time Restricted Shares equal 50% of each participant’s total equity award and vest 25% per year over four years, generally contingent on continued employment. Performance Restricted Shares equal the other 50% and vest after a three-year period based on return on equity and book value performance goals, with sliding vesting between minimum, target, and maximum thresholds and potential Additional Shares above 100% of target.
On January 27, 2026, Unitil granted Time Restricted Shares and Performance Restricted Shares to key officers, including 8,090 of each type to Chairman and CEO Thomas P. Meissner Jr., 3,740 each to President and Chief Administrative Officer Robert B. Hevert, and 2,430 each to Senior Vice President, Chief Financial Officer and Treasurer Daniel J. Hurstak. The company also granted unrestricted common shares based on exceeding combined target performance goals for 2023–2025, including 310 shares to Meissner and 90 shares to Hevert under its Third Amended and Restated 2003 Stock Plan.
Unitil Corporation filed an 8-K describing an amendment to its previously announced agreement to acquire Aquarion Water Company of Massachusetts, Inc., Aquarion Water Company of New Hampshire, Inc., and Abenaki Water Co., Inc. from Aquarion Water Authority.
The amendment, dated January 23, 2026, changes the Purchase Agreement’s “Termination Date” from January 23, 2026 to February 23, 2026, effectively giving the parties an additional month to close the transaction or meet remaining conditions. All other terms of the Purchase Agreement remain in place, and Unitil states that it and its controlled affiliates have no material relationships with the seller or the South Central Connecticut Regional Water Authority other than this transaction.
Unitil Corporation reported an upcoming leadership transition in its corporate governance team. Corporate Secretary Sandra L. Whitney has given notice that she will retire and resign from the company and its subsidiaries effective at the end of the day on December 31, 2025.

He will continue serving as General Counsel while taking on the additional Corporate Secretary role. The company expects Ms. Whitney to provide consulting services through April 30, 2026 to support a smooth transition of responsibilities.

On October 31, 2025, Unitil entered into a senior unsecured delayed draw term Credit Agreement with The Bank of Nova Scotia for up to $86 million. Borrowings are permitted until October 31, 2026, with all amounts due at that time. Unitil borrowed $86.0 million on the closing date to partially finance the acquisition.

Covenants include limits on additional liens, debt, investments, dividends, guarantees, mergers and business changes, and a financial covenant capping Funded Debt to Capitalization at 65%, tested quarterly.
