The Company summarized the material terms and conditions of the Distribution Agreement in a Current Report on Form 8-K dated June 3, 2025.
On February 19, 2026, (i) the Company and Janney Montgomery Scott LLC mutually terminated the Distribution Agreement with respect to Janney Montgomery Scott LLC, in its capacity as an agent and/or forward seller and as a forward purchaser thereunder and (ii) the Company entered into Amendment No. 1 to Distribution Agreement (the “Amendment to Distribution Agreement”) with Huntington Securities, Inc. and Scotia Capital (USA) Inc., as agents and/or forward sellers, and Huntington Securities, Inc. and The Bank of Nova Scotia, as forward purchasers. The Amendment to Distribution Agreement amended the Distribution Agreement to replace Janney Montgomery Scott LLC, in its capacities as an agent and/or forward seller and as a forward purchaser, with Huntington Securities, Inc.
The offer and sales of the Shares, if any, made pursuant to the Distribution Agreement (as amended), will be made under the Company’s Registration Statement on Form S-3ASR, which was previously filed with the Securities and Exchange Commission and became automatically effective on June 3, 2025, as supplemented by a prospectus supplement, dated June 3, 2025 and a prospectus supplement no. 1, dated February 19, 2026.
Neither the Company nor any of its controlled affiliates has any material relationship with Huntington Securities, Inc., Scotia Capital (USA) Inc., or The Bank of Nova Scotia, other than with respect to (i) the Distribution Agreement, as amended, (ii) the debt commitment letter dated May 6, 2025 between the Company and The Bank of Nova Scotia relating to the acquisition of Aquarion Water Company of Massachusetts, Inc., Aquarion Water Company of New Hampshire, Inc., and Abenaki Water Co., Inc., (iii) advice provided by The Bank of Nova Scotia or its affiliates in connection with the acquisition of Aquarion Water Company of Massachusetts, Inc., Aquarion Water Company of New Hampshire, Inc., and Abenaki Water Co., Inc., (iv) the Credit Agreement dated as of October 31, 2025 among the Company, The Bank of Nova Scotia, as a lender, and The Bank of Nova Scotia, as administrative agent, relating to the acquisition of Maine Natural Gas Corporation, (v) advice provided by The Bank of Nova Scotia or its affiliates in connection with the acquisition of Maine Natural Gas Corporation, (vi) the debt commitment letter dated July 8, 2024 between the Company and The Bank of Nova Scotia relating to the acquisition of Bangor Natural Gas Company, (vii) advice provided by The Bank of Nova Scotia or its affiliates in connection with the acquisition of Bangor Natural Gas Company, and (viii) other customary banking and investment banking relationships.
The foregoing description of the material terms of the Amendment to Distribution Agreement does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Amendment to Distribution Agreement. A copy of the Amendment to Distribution Agreement is filed as Exhibit 10.1 hereto.
The Amendment to Distribution Agreement has been included to provide investors with information regarding its terms. The Amendment to Distribution Agreement is not intended to provide any factual information about the Company or any of its subsidiaries. The representations, warranties and covenants contained in the Amendment to Distribution Agreement were, are or will be made only for purposes of the Amendment to Distribution Agreement and as of specific dates, are solely for the benefit of the parties to the Amendment to Distribution Agreement, and are subject to limitations, modifications, qualifications, or exceptions agreed upon by the parties to the Amendment to Distribution Agreement. Moreover, the representations and warranties contained in the Amendment to Distribution Agreement generally were,
are or will be made for the purpose of allocating contractual risk among the parties to the Amendment to Distribution Agreement instead of establishing matters as facts, and may be subject to standards of materiality applicable to the parties to the Amendment to Distribution Agreement that differ from those applicable to investors. Investors are not third-party beneficiaries under the Amendment to Distribution Agreement and should not rely on the representations, warranties and covenants contained therein or any descriptions thereof as characterizations of the actual state of facts or condition of the Company or its subsidiaries or any of their respective subsidiaries or affiliates. Additionally, information concerning the subject matter of the representations and warranties contained in the Amendment to Distribution Agreement may change after the date of the Amendment to Distribution Agreement, which subsequent information may or may not be fully reflected in the Company’s public disclosures.
This Current Report on Form 8-K shall not constitute an offer to sell or the solicitation of any offer to buy the Shares, nor shall there be an offer, solicitation or sale of the Shares in any state in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of such state.
Amendment to Purchase Agreement
As previously reported, on May 6, 2025, the Company entered into a Purchase and Sale Agreement (the “Purchase Agreement”) by and between the Company and Aquarion Water Authority, a public corporation and political subdivision of the state of Connecticut (“Seller”), and, solely with respect to Section 9.25 and Section 9.26 thereof, South Central Connecticut Regional Water Authority (“RWA”). Pursuant to the Purchase Agreement, the Company agreed to acquire all of the issued and outstanding shares of common stock of Aquarion Water Company of Massachusetts, Inc., Aquarion Water Company of New Hampshire, Inc., and Abenaki Water Co., Inc. from Seller. The Company summarized the material terms and conditions of the Purchase Agreement in a Current Report on Form 8-K dated May 6, 2025.
As previously disclosed, on January 23, 2026, the Company entered into an Amendment No. 1 to Purchase and Sale Agreement (“Amendment No. 1”) by and between the Company, Seller and RWA. Amendment No. 1, among other things, amended the definition of “Termination Date” in Section 8.1(d) of the Purchase Agreement by replacing the reference to “January 23, 2026” with “February 23, 2026”. Except as specifically modified and amended by Amendment No. 1, the Purchase Agreement remained unchanged. The Company summarized the material terms and conditions of Amendment No. 1 in a Current Report on Form 8-K dated January 23, 2026.
On February 23, 2026, the Company entered into an Amendment No. 2 to Purchase and Sale Agreement (“Amendment No. 2”) by and between the Company, Seller and RWA. Amendment No. 2, among other things, further amended the definition of “Termination Date” in Section 8.1(d) of the Purchase Agreement by replacing the reference to “February 23, 2026” with “May 25, 2026”. Except as specifically modified and amended by Amendment No. 2, the Purchase Agreement remains unchanged.
Neither the Company nor any of its controlled affiliates has any material relationship with Seller or RWA, other than with respect to the Purchase Agreement, Amendment No. 1 and Amendment No. 2.

The representations, warranties and covenants contained in Amendment No. 2 were made only for purposes of Amendment No. 2 and as of specific dates and were solely for the benefit of the parties to Amendment No. 2. Moreover, the representations and warranties contained in Amendment No. 2 generally were made for the purpose of allocating contractual risk among the parties to Amendment No. 2 instead of establishing matters as facts, and may be subject to standards of materiality applicable to the parties to Amendment No. 2 that differ from those applicable to investors. Investors are not third-party beneficiaries under Amendment No. 2 and should not rely on the representations, warranties and covenants contained
therein or any descriptions thereof as characterizations of the actual state of facts or condition of the Company or any of its subsidiaries or affiliates. Additionally, information concerning the subject matter of the representations and warranties contained in Amendment No. 2 may change after the date of Amendment No. 2, which subsequent information may or may not be fully reflected in the Company’s public disclosures.
