Unitil Corporation has issued its 2026 proxy statement for the April 29, 2026 annual meeting in Hampton, New Hampshire. Shareholders will vote on electing three Class II directors, ratifying Deloitte & Touche LLP as independent auditor for 2026, and approving executive pay on an advisory basis.
The proxy highlights 17,986,069 common shares outstanding as of the February 20, 2026 record date, extensive board‑level governance, risk and cybersecurity oversight, and strong emphasis on sustainability and human capital. It also reviews 2025 achievements, including gas utility acquisitions, major infrastructure and solar investments, and dividend increases to $1.80 per share for 2025 and $1.90 for 2026.
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.
UTL amends its prospectus supplement to update an at-the-market offering program for up to $50,000,000 of common stock. The supplement reflects the removal of Janney and addition of Huntington Securities, Inc. as a sales agent and forward purchaser under the distribution agreement.
The company has sold approximately 27,620 shares for proceeds before commissions of approximately $1.5 million, leaving approximately $48.5 million available under the program. The offering permits sales directly by the company, sales by agents as principals, and the use of forward sale agreements; the company may receive proceeds only on physical settlement of forward sales and may receive no proceeds if forward agreements are cash or net share settled. The company’s common stock trades on the NYSE; the last reported sale price on February 17, 2026 was $52.91 per share.
Unitil Corporation filed its annual report detailing 2025 performance and continued expansion as a regulated electric and natural gas utility across New Hampshire, Massachusetts and Maine. The company served about 215,100 customers and generated $536.0 million in total operating revenue.
Electric distribution produced $236.4 million of revenue and gas operations $299.6 million, with most earnings coming from regulated distribution and pipeline returns rather than commodity margins. Net utility plant reached $1.8 billion, reflecting ongoing investment in wires, pipes and related infrastructure.
Unitil completed acquisitions of Bangor Natural Gas Company and Maine Natural Gas Corporation, adding roughly 15,000 Maine gas customers and broadening its regulated footprint. GAAP net income for 2025 was $50.2 million (including acquisition-related transaction costs), compared with $47.1 million in 2024. Management also highlights adjusted non‑GAAP net income to strip out these deal expenses.
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.
