Section 2- Financial Information

Item 2.02 Results of Operations and Financial Condition.

On October 14, 2025, Eversource Energy (“Eversource”) issued a news release providing an update on offshore wind liability including certain unaudited financial information for the three-month period ended September 30, 2025. A copy of the news release is attached as Exhibit 99.1 and is incorporated herein by reference hereto.

The information contained in this Item 2.02, including Exhibit 99.1, shall not be deemed “filed” with the Securities and Exchange Commission (“SEC”) nor incorporated by reference in any registration statement filed by Eversource Energy or any subsidiary thereof under the Securities Act of 1933, as amended (the “Securities Act”), unless specified otherwise.

Section 8 - Other Events

Item 8.01 Other Events.

On September 30, 2024, Eversource sold its interests in in the 132-megawatt South Fork Wind project (“South Fork Wind”), which is operational, and the 704-megawatt Revolution Wind project (“Revolution Wind”), which is under construction, (collectively, the “Offshore Wind Projects”) to affiliates of Global Infrastructure Partners (“GIP”).

As part of the sale of the Offshore Wind Projects, Eversource and GIP agreed to make certain post-closing purchase price adjustments that will impact the final purchase price. Upon closing of the sale, Eversource recorded a $365 million contingent liability as of September 30, 2024, reflecting its estimate of the future obligations under the terms of the sale to GIP. These obligations included an expected cost overrun sharing obligation, an expected obligation to maintain GIP’s internal rate of return, and an obligation for other future costs. Certain payments made in 2025 reduced this liability, which was $296 million as of June 30, 2025. As the Offshore Wind Projects progress and final costs materialize, Eversource continues to review its obligations with respect to the project to determine if any changes to this liability are warranted as Revolution Wind project completes construction.

In the third quarter of 2025, Eversource received an updated report on the construction status of Revolution Wind from GIP that included revised projections of total construction costs. The revised cost projections reflect known and quantifiable cost overruns, including those associated with the impacts of damage to the wind turbine installation vessel, insurance costs and costs incurred as a result of the stop-work order for Revolution Wind received on August 22, 2025 from the Bureau of Ocean Energy Management (“BOEM”) that halted all offshore wind construction activities through September 22, 2025. The aggregate impact of these amounts is currently estimated to be approximately $285 million, which is expected to result in a charge to be recogniz

Item 7.01Regulation FD Disclosure.

On September 30, 2024, Eversource Energy (“Eversource” or the “Company”) issued a news release announcing that the Company has completed the sale of its 50 percent interest in the 132-megawatt South Fork Wind project (“South Fork Wind”) and the 704-megawatt Revolution Wind project (“Revolution Wind”) to affiliates of Global Infrastructure Partners (“GIP”). The news release is attached as Exhibit 99.1 and incorporated herein by reference.

The information contained in this Item 7.01, including Exhibit 99.1, shall not be deemed “filed” with the Securities and Exchange Commission (“SEC”) nor incorporated by reference in any registration statement filed by Eversource or any subsidiary thereof under the Securities Act of 1933, as amended, unless specified otherwise.

Section 8Other Events

Item 8.01Other Events.

On September 30, 2024, Eversource announced that the Company has completed the sale of its 50 percent share in the 132-megawatt South Fork Wind project and the 704-megawatt Revolution Wind project to GIP. Adjusted gross proceeds from the transaction payable at closing were $745 million. Adjusted gross proceeds from the sale were reduced by approximately $375 million as compared with the previously estimated purchase price of approximately $1.12 billion. This reduction reflects an approximately $150 million reduction resulting from lower capital spending between announcing the transaction and closing, and an approximately $225 million reduction primarily due to the delay of the commercial operations date of Revolution Wind.

With the completion of this sale and the previously completed sale of the Company’s 50 percent interest in the Sunrise Wind project (“Sunrise Wind”) to Ørsted consumated on July 9, 2024, Eversource expects to record an aggregate net loss on the completion of its offshore wind divesture of approximately $520 million in the third quarter of 2024. This aggregate net loss includes the final gain on the sale of Sunrise Wind of $370 million and anticipated increases in Revolution Wind construction costs and other project related charges. This estimate is subject to change as Eversource finalizes results for the third quarter ended September 30, 2024. Eversource expects to recognize a liability of approximately $360 million, which is included as part of the aggregate net loss of $520 million on the sale, in the third quarter of 2024. The majority of this liability is expected to be settled in 2026.

With the closing of this transaction, and the previously announced sale of Eversource’s 50 percent interest in Sunrise Wind, Eversourc

On January 24, 2024, Sunrise Wind, an offshore wind project jointly owned 50 percent by Eversource Energy (“Eversource”) and 50 percent by Ørsted, issued a news release announcing that Ørsted has signed an agreement with Eversource to acquire Eversource’s 50 percent share of Sunrise Wind, a 924 MW offshore wind farm, which would deliver power to New York. The acquisition is subject to the successful award of Sunrise Wind in the ongoing New York 4 solicitation for offshore wind capacity, signing of an OREC (“Offshore Wind Renewable Energy Certificates”) contract with the New York State Energy Research and Development Authority (“NYSERDA”), finalization of acquisition agreements, receipt of construction and operations plan (“COP”), and relevant regulatory approvals.

The news release is attached as Exhibit 99.1 and incorporated herein by reference.

The information contained in this Item 7.01, including Exhibit 99.1, shall not be deemed “filed” with the Securities and Exchange Commission (“SEC”) nor incorporated by reference in any registration statement filed by Eversource or any subsidiary thereof under the Securities Act of 1933, as amended, unless specified otherwise.

The acquisition is subject to the successful award of Sunrise Wind in the ongoing New York 4 solicitation for offshore wind capacity, signing of an OREC contract with NYSERDA, finalization of acquisition agreements, receipt of construction and operations plan, and relevant regulatory approvals.

If Sunrise Wind is not successful in the solicitation, then the existing OREC contract for Sunrise Wind will be cancelled per the state’s requirements, and Eversource and Ørsted’s 50/50 joint venture for Sunrise Wind will remain in place. In that scenario, the joint venture will evaluate its next steps. If the project is provisionally awarded, a new contract will be negotiated with NYSERDA under the updated terms of the current solicitation.

As the most mature offshore wind project in New York’s pipeline, Sunrise Wind is, if awarded in the New York 4 solicitation, expected to be completed in 2026, helping New York achieve its goal of reaching 70 percent renewable energy by 2030.

Item 7.01Regulation FD Disclosure.

On January 8, 2024, Eversource Energy (“Eversource”) issued a news release announcing updates regarding the process to divest its 50 percent ownership interest in three offshore wind projects: South Fork Wind, Revolution Wind and Sunrise Wind. The news release is attached as Exhibit 99.1 and incorporated herein by reference.

The information contained in this Item 7.01, including Exhibit 99.1, shall not be deemed “filed” with the Securities and Exchange Commission (“SEC”) nor incorporated by reference in any registration statement filed by Eversource or any subsidiary thereof under the Securities Act of 1933, as amended, unless specified otherwise.

Section 8Other Events

Item 8.01Other Events.

On January 8, 2024, Eversource provided the following updates regarding the process to divest its 50 percent ownership interest in three offshore wind projects: South Fork Wind, Revolution Wind and Sunrise Wind. Eversource currently holds its share of these three projects in two separate joint venture partnerships with Ørsted (each, a “JV”), one that holds only South Fork Wind and another that holds both Revolution Wind and Sunrise Wind. Eversource also separately holds a tax equity investment in South Fork Wind.

Eversource is in advanced, exclusive negotiations with the selected buyer (the “Buyer”), which is a leading global private infrastructure investor, to sell its ownership interest in these projects. Although Eversource cannot provide any assurance that the parties will reach final agreement on terms for this transaction, if successful in reaching an agreement, Eversource will announce the details of the transaction terms and conditions promptly upon execution of such definitive documentation.

Closing a transaction with the Buyer would be subject to customary conditions, including certain regulatory approvals under the Hart Scott Rodino Act and at the Federal Energy Regulatory Commission, as well as other conditions, among which, are the completion and execution of the partnership agreements between the Buyer and Ørsted that will govern the Buyer’s new ownership interest following Eversource’s divestiture. The scope of the transaction would also be subject to the developments with respect to the Sunrise Wind rebid process.

During the fourth quarter of 2023, Eversource identified certain impacts that will require further adjustment to the carrying value of its offshore wind investments for the three projects. Revised projected construction costs caused primarily by supply chain constraints relating to the projects’ installation vess
