Item 1.01 Entry into a Material Definitive Agreement. Item 1.01 On October 20, 2025 (the “Signing Date”), CenterPoint Energy Resources Corp., a Delaware corporation (“Seller”) and a wholly owned, indirect subsidiary of CenterPoint Energy, Inc. (the “Company”), entered into a Securities Purchase Agreement (the “Purchase Agreement”) by and between Seller and National Fuel Gas Company, a New Jersey corporation (the “Buyer”), pursuant to which Seller has agreed to sell all of the issued and outstanding equity interests (the “LLC Interests”) in Vectren Energy Delivery of Ohio, LLC, an Ohio limited liability company (“VEDO”), to Buyer (the “Transaction”). The purchase price for the LLC Interests is $2.62 billion (the “Purchase Price”), subject to adjustment as set forth in the Purchase Agreement. The Purchase Price to be paid by the Buyer to the Seller under the Purchase Agreement in the Transaction is comprised of the following: (i) $1.42 billion in cash (the “Cash Payment”) payable by the Buyer to the Seller upon closing of the Transaction (the “Closing”), subject to adjustments as set forth in the Purchase Agreement, including adjustments based on net working capital, regulatory assets and liabilities and capital expenditures at Closing; and (ii) a 364-day seller promissory note, in the original principal amount of $1.2 billion (the “Loan”), to be issued by the Buyer at the Closing and payable to Seller as provided by the terms and conditions of a Seller Note Agreement (such promissory note and agreement, collectively, the “Seller Note”) to be executed at the Closing in the form attached to the Purchase Agreement and as described in greater detail under Item 8.01 of this Current Report on From 8-K (this “Current Report”). The completion of the Transaction is subject to customary closing conditions, including (i) the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended; (ii) completion of a notice filing and review with the Public Utilities Commission of Ohio; and (iii) customary conditions regarding the accuracy of the representations and warranties and compliance by the parties with their respective obligations under the Purchase Agreement. The Transaction is not subject to a financing condition. The Transaction is subject to an inside date of October 1, 2026 and expected to close in Q4 2026, subject to satisfaction of the foregoing conditions. The Purchase Agreement contains customary representations, warranties and covenants related to VEDO, the LLC Interests and the Transaction. Between the date of the Purchase Agreement and the completion of the Transaction, Seller has agreed to cause VEDO to operate in the ordinary course of business and has agreed to certain other operating covenants with respect to VEDO as set forth in the Purchase Agreement. The parties have agreed to customary interim operating covenants, including debt financing cooperation, regulatory coordination and cooperation, treatment of certain shared contracts and transition planning. The Seller has agreed to a customary exclusivity provision with respect to VEDO during the pendency of the Transaction. On a post-Closing basis, the parties have agreed to certain cooperation covenants with respect to the transition of certain assets and contracts (including government contracts), transition services and non-solicitation and non-disparagement obligations. The Purchase Agreement includes customary termination provisions, including the abilities of the parties to extend the term of the Purchase Agreement under certain conditions if the Closing of the Transaction has not occurred within 18 months of the Signing Date, which may be extended by either Seller or Buyer up to 21 months after the Signing Date, and further extended by mutual agreement up to 24 months after the Signing Date. Extension rights are only available if all closing conditions have been met except those pertaining to regulatory approvals and the absence of restrictions of law that prohibit the consummation of the Transaction. A termination fee is payable by Buyer to Seller in certain scenarios where the Purchase Agreement is terminated for an uncured material breach resulting in a failure of a closing condition or due to certain regulatory restraints with respect to the consummation of the Transaction. The foregoing description of the Purchase Agreement does not purport to be complete and is qualified in its entirety by reference to the complete text of the Purchase Agreement. A copy of the Purchase Agreement is filed as Exhibit 2.1 to this Current Report and is incorporated herein by reference. The representations, warranties and covenants set forth in the Purchase Agreement have been made only for the purposes of the Purchase Agreement and solely for the benefit of the parties thereto and may be subject to limitations agreed upon by the contracting parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the Purchase Agreement instead of establishing these matters as facts. In addition, such representations and warranties were made only as of the dates specified in the Purchase Agreement and information regarding the subject matter thereof may change after the date of the Purchase Agreement. Accordingly, the Purchase Agreement is included with this filing only to provide investors with information regarding its terms and not to provide investors with any other factual information regarding the Company, Seller or VEDO, as of the date of the Purchase Agreement or as of any other date. Investors should not rely on such representations and warranties as characterizations of the actual state of facts or circumstances, since they were made only as of a specific date, were negotiated by the parties and are modified in important part by the underlying disclosure schedules. In addition, certain representations and warranties may be subject to a contractual standard of materiality different from what might be viewed as material to shareholders.
