EVERSOURCE ENERGY AND SUBSIDIARIES
THE CONNECTICUT LIGHT AND POWER COMPANY
NSTAR ELECTRIC COMPANY AND SUBSIDIARY
PUBLIC SERVICE COMPANY OF NEW HAMPSHIRE AND SUBSIDIARIES
COMBINED NOTES TO CONDENSED FINANCIAL STATEMENTS (Unaudited)
Refer to the Glossary of Terms included in this combined Quarterly Report on Form 10-Q for abbreviations and acronyms used throughout the combined notes to the unaudited condensed financial statements.
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
A. Basis of Presentation
Eversource Energy is a public utility holding company primarily engaged, through its wholly-owned regulated utility subsidiaries, in the energy delivery business. Eversource Energy's wholly-owned regulated utility subsidiaries consist of CL&P, NSTAR Electric and PSNH (electric utilities), Yankee Gas, NSTAR Gas and EGMA (natural gas utilities), and Aquarion (water utilities). Eversource provides energy delivery and/or water service to approximately 4.6 million electric, natural gas and water customers through twelve regulated utilities in Connecticut, Massachusetts and New Hampshire.
The unaudited condensed consolidated financial statements of Eversource, NSTAR Electric and PSNH include the accounts of each of their respective subsidiaries. Intercompany transactions have been eliminated in consolidation. The accompanying unaudited condensed consolidated financial statements of Eversource, NSTAR Electric and PSNH and the unaudited condensed financial statements of CL&P are herein collectively referred to as the "financial statements."
The combined notes to the financial statements have been prepared pursuant to the rules and regulations of the SEC. Certain information and footnote disclosures included in annual financial statements prepared in accordance with GAAP have been omitted pursuant to such rules and regulations. The accompanying financial statements should be read in conjunction with the Combined Notes to Financial Statements included in Item 8, "Financial Statements and Supplementary Data," of the Eversource 2024 Form 10-K, which was filed with the SEC on February 14, 2025. The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
The financial statements contain, in the opinion of management, all adjustments (including normal, recurring adjustments) necessary to present fairly Eversource's, CL&P's, NSTAR Electric's and PSNH's financial position as of June 30, 2025 and December 31, 2024, and the results of operations, comprehensive income, common shareholders' equity for the three and six months ended June 30, 2025 and 2024, and the cash flows for the six months ended June 30, 2025 and 2024. The results of operations, comprehensive income for the three and six months ended June 30, 2025 and 2024 and the cash flows for the six months ended June 30, 2025 and 2024 are not necessarily indicative of the results expected for a full year.
CYAPC and YAEC are inactive regional nuclear power companies engaged in the long-term storage of their spent nuclear fuel. Eversource consolidates the operations of CYAPC and YAEC because CL&P's, NSTAR Electric's and PSNH's combined ownership and voting interests in each of these entities is greater than 50 percent. Intercompany transactions between CL&P, NSTAR Electric, PSNH and the CYAPC and YAEC companies have been eliminated in consolidation of the Eversource financial statements.
Eversource's utility subsidiaries' electric, natural gas and water distribution and transmission businesses are subject to rate-regulation that is based on cost recovery and meets the criteria for application of accounting guidance for entities with rate-regulated operations, which considers the effect of regulation on the differences in the timing of the recognition of certain revenues and expenses from those of other businesses and industries. See Note 2, "Regulatory Accounting," for further information.
Certain reclassifications of prior period data were made in the accompanying financial statements to conform to the current period presentation.
B. Accounting Standards
Accounting Standards Issued but Not Yet Adopted: In December 2023, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) 2023-09, Income Taxes (Topic 740) - Improvements to Income Tax Disclosures, which requires enhanced income tax disclosures, primarily requiring consistent categories and greater detailed disclosure information in the tax rate reconciliation as well as income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for annual periods beginning after December 15, 2024, with early adoption permitted and may be applied on either a prospective or retrospective basis. Eversource expects to adopt the amendments to this standard prospectively upon effective date and does not expect an impact on the financial statements of Eversource, CL&P, NSTAR Electric and PSNH.
C. Allowance for Uncollectible Accounts
Receivables, Net on the balance sheets primarily includes trade receivables from retail customers and customers related to wholesale transmission contracts, wholesale market sales, sales of RECs, and property rentals. Receivables, Net also includes customer receivables for the purchase of electricity from a competitive third party supplier, the current portion of customer energy efficiency loans, property damage receivables and other miscellaneous receivables. There is no material concentration of receivables.
17

Receivables are recorded at amortized cost, net of a credit loss provision (or allowance for uncollectible accounts). The current expected credit loss (CECL) model is applied to receivables for purposes of calculating the allowance for uncollectible accounts. This model is based on expected losses and results in the recognition of estimated expected credit losses, including uncollectible amounts for both billed and unbilled revenues, over the life of the receivable at the time a receivable is recorded.
The allowance for uncollectible accounts is determined based upon a variety of judgments and factors, including an aging-based quantitative assessment that applies an estimated uncollectible percentage to each receivable aging category. Factors in determining credit loss include historical collection, write-off experience, analysis of delinquency statistics, and management's assessment of collectability from customers, including current economic conditions, customer payment trends, the impact on customer bills because of energy usage trends and changes in rates, flexible payment plans and financial hardship arrearage management programs offered to customers, reasonable forecasts, and expectations of future collectability and collection efforts. Management continuously assesses the collectability of receivables and adjusts estimates based on actual experience and future expectations based on economic conditions, collection efforts and other factors. Management also monitors the aging analysis of receivables to determine if there are changes in the collections of accounts receivable. Receivable balances are written off against the allowance for uncollectible accounts when the customer accounts are no longer in service and these balances are deemed to be uncollectible. Management concluded that the reserve balance as of June 30, 2025 adequately reflected the collection risk and net realizable value for its receivables.
The PURA allows CL&P and Yankee Gas to accelerate the recovery of accounts receivable balances attributable to qualified customers under financial or medical duress (uncollectible hardship accounts receivable) outstanding for greater than 180 days and 90 days, respectively. The DPU allows NSTAR Electric, NSTAR Gas and EGMA to recover in rates amounts associated with certain uncollectible hardship accounts receivable. These uncollectible hardship customer account balances are included in Regulatory Assets or Other Long-Term Assets on the balance sheets. Hardship customers are protected from shut-off in certain circumstances, and historical collection experience has reflected a higher default risk as compared to the rest of the receivable population. Management uses a higher credit risk profile for this pool of trade receivables as compared to non-hardship receivables. The allowance for uncollectible hardship accounts is included in the total uncollectible allowance balance.
The total allowance for uncollectible accounts is included in Receivables, Net on the balance sheets. The activity in the allowance for uncollectible accounts by portfolio segment as of June 30 th is as follows:

(1) These expected credit losses are deferred as regulatory costs on the balance sheets, as these amounts are ultimately recovered in rates. Amounts include uncollectible costs for hardship accounts and other customer receivables, including uncollectible amounts related to uncollectible energy supply costs.
As of both June 30, 2025 and December 31, 2024, the allowance for uncollectible accounts attributable to the Aquarion water distribution business has been reclassified to Assets Held for Sale on the Eversource balance sheets. For further information, see Note 17, “Assets Held for Sale.”
D. Fair Value Measurements
Fair value measurement guidance is applied to derivative contracts that are not elected or designated as "normal purchases" or "normal sales" (normal) and to marketable securities held in trusts. Fair value measurement guidance is also applied to valuations of the investments used to calculate the funded status of pension and PBOP plans, the nonrecurring fair value measurements of nonfinancial assets such as goodwill, long-lived assets, equity method investments, AROs, and in the valuation of business combinations and asset acquisitions. The fair value measurement guidance was also applied in estimating the fair value of preferred stock, long-term debt and RRBs.
Fair Value Hierarchy: In measuring fair value, Eversource uses observable market data when available in order to minimize the use of unobservable inputs. Inputs used in fair value measurements are categorized into three fair value hierarchy levels for disclosure purposes. The entire fair value measurement is categorized based on the lowest level of input that is significant to the fair value measurement. Eversource evaluates the classification of assets and liabilities measured at fair value on a quarterly basis.
The levels of the fair value hierarchy are described below:
Level 1 - Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis.
Level 2 - Inputs are quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which all significant inputs are observable.
Level 3 - Quoted market prices are not available. Fair value is derived from valuation techniques in which one or more significant inputs or assumptions are unobservable. Where possible, valuation techniques incorporate observable market inputs that can be validated to external sources such as industry exchanges, including prices of energy and energy-related products.
Uncategorized - Investments that are measured at net asset value are not categorized within the fair value hierarchy.
Determination of Fair Value: The valuation techniques and inputs used in Eversource's fair value measurements are described in Note 4, "Derivative Instruments," Note 5, "Marketable Securities," and Note 10, "Fair Value of Financial Instruments," to the financial statements.

Restricted cash included in Marketable Securities represents money market funds held in restricted trusts to fund CYAPC and YAEC's spent nuclear fuel storage obligations.
Eversource’s restricted cash also includes an Energy Relief Fund for energy efficiency and clean energy measures in the Merrimack Valley established under the terms of an EGMA 2020 settlement agreement. This restricted cash held in escrow accounts included $20.0 million recorded as short-term in Special Deposits as of both June 30, 2025 and December 31, 2024, and $5.7 million and $5.9 million recorded in Other Long-Term Assets on the balance sheets as of June 30, 2025 and December 31, 2024, respectively.
2. REGULATORY ACCOUNTING
Eversource's utility companies are subject to rate regulation that is based on cost recovery and meets the criteria for application of accounting guidance for rate-regulated operations, which considers the effect of regulation on the timing of the recognition of certain revenues and expenses. The regulated companies' financial statements reflect the effects of the rate-making process. The rates charged to the customers of Eversource's regulated companies are designed to collect each company's costs to provide service, including a return on investment.
The application of accounting guidance for rate-regulated enterprises results in recording regulatory assets and liabilities. Regulatory assets represent the deferral of incurred costs that are probable of future recovery in customer rates. Regulatory assets are amortized as the incurred costs are recovered through customer rates. Regulatory liabilities represent either revenues received from customers to fund expected costs that have not yet been incurred or probable future refunds to customers.
Management believes it is probable that each of the regulated companies will recover its respective investments in long-lived assets and the regulatory assets that have been recorded. If management were to determine that it could no longer apply the accounting guidance applicable to rate-regulated enterprises, or if management could not conclude it is probable that costs would be recovered from customers in future rates, the applicable costs would be charged to net income in the period in which the determination is made.

Regulatory Costs in Other Long-Term Assets: Eversource's regulated companies had $259.2 million (including $138.9 million for CL&P, $47.5 million for NSTAR Electric and $7.0 million for PSNH) and $221.0 million (including $116.3 million for CL&P, $41.1 million for NSTAR Electric and $4.5 million for PSNH) of additional regulatory costs not yet specifically approved as of June 30, 2025 and December 31, 2024, respectively, that were included in Other Long-Term Assets on the balance sheets. These amounts will be reclassified to Regulatory Assets upon approval by the applicable regulatory agency. Based on regulatory policies or past precedent on similar costs, management believes it is probable that these costs will ultimately be approved and recovered from customers in rates. As of June 30, 2025 and December 31, 2024, these regulatory costs included $124.8 million (including $68.2 million for CL&P and $31.8 million for NSTAR Electric) and $92.5 million (including $47.2 million for CL&P and $24.4 million for NSTAR Electric), respectively, of deferred uncollectible hardship costs.

As of both June 30, 2025 and December 31, 2024, the property, plant and equipment balance, net of accumulated depreciation, attributable to the Aquarion water distribution business has been reclassified to Assets Held for Sale on the Eversource balance sheets. For further information, see Note 17, “Assets Held for Sale.”
4. DERIVATIVE INSTRUMENTS
The electric and natural gas companies purchase and procure energy and energy-related products, which are subject to price volatility, for their customers. The costs associated with supplying energy to customers are recoverable from customers in future rates. These regulated companies manage the risks associated with the price volatility of energy and energy-related products through the use of derivative and non-derivative contracts. Many of the derivative contracts meet the definition of, and are designated as, normal and qualify for accrual accounting under the applicable accounting guidance. The costs and benefits of derivative contracts that meet the definition of normal are recognized in Operating Expenses on the statements of income as electricity or natural gas is delivered.
Derivative contracts that are not designated as normal are recorded at fair value as derivative assets or liabilities on the balance sheets. For the electric and natural gas companies, regulatory assets or regulatory liabilities are recorded to offset the fair values of derivatives, as contract settlement amounts are recovered from, or refunded to, customers in their respective energy supply rates.
The gross fair values of derivative assets and liabilities with the same counterparty are offset and reported as net Derivative Assets or Derivative Liabilities, with current and long-term portions, on the balance sheets. The following table presents the gross fair values of contracts, categorized by risk type, and the net amounts recorded as current or long-term derivative assets or liabilities:

|  |  | As of June 30, 2025 |  | As of December 31, 2024
CL&P (Millions of Dollars) | Fair Value Hierarchy |  | Commodity Supply and Price Risk Management |  | Netting (1) |  | Net Amount Recorded as a Derivative |  | Commodity Supply and Price Risk Management |  | Netting (1) |  | Net Amount Recorded as a Derivative
Current Derivative Assets | Level 2 |  | $ | 6.5 |  |  | $ | (0.3) |  |  | $ | 6.2 |  |  | $ | 14.2 |  |  | $ | (0.3) |  |  | $ | 13.9 |
Current Derivative Liabilities | Level 2 |  | (32.5) |  |  | — |  |  | (32.5) |  |  | (71.1) |  |  | — |  |  | (71.1) |

(1) Amounts represent derivative assets and liabilities that Eversource elected to record net on the balance sheets. These amounts are subject to master netting agreements or similar agreements for which the right of offset exists.
Derivative Contracts at Fair Value with Offsetting Regulatory Amounts
Commodity Supply and Price Risk Management: As required by regulation, CL&P, along with UI, has capacity-related contracts with generation facilities. CL&P has a sharing agreement with UI, with 80 percent of the costs or benefits of each contract borne by or allocated to CL&P and 20 percent borne by or allocated to UI. The combined capacities of these contracts as of June 30, 2025 and December 31, 2024 were 609 MW and 610 MW, respectively. The capacity contracts extend through 2026 and obligate both CL&P and UI to make or receive payments on a monthly basis to or from the generation facilities based on the difference between a set capacity price and the capacity market price received in the ISO-NE capacity markets.
For the three months ended June 30, 2025 and 2024, there were losses of $0.3 million and $1.9 million, respectively. For the six months ended June 30, 2025 and 2024, there were losses of $0.6 million and $2.9 million, respectively. These changes in fair value associated with CL&P’s derivative contracts are deferred in Regulatory Assets on the balance sheet.
NSTAR Electric is reviewing a significant anticipated power purchase obligation that is expected to be marked to market on the balance sheet as a material derivative liability in 2025. The agreement for the purchase of clean energy and renewable energy attributes was entered into to satisfy Massachusetts legislation and is a 20-year contract with estimated total payments of $6.7 billion. The resulting derivative liability is expected to be fully offset by a regulatory asset for recovery from NSTAR Electric’s customers.
Fair Value Measurements of Derivative Instruments
The fair value of derivative contracts utilizes both observable and unobservable inputs. The fair value is modeled using income techniques, such as discounted cash flow valuations adjusted for assumptions related to exit price. Valuations of derivative contracts using a discounted cash flow methodology include assumptions regarding the timing and likelihood of scheduled capacity payments and also reflect non-performance risk, including credit, using the default probability approach based on the counterparty's credit rating for assets and the Company's credit rating for liabilities. Significant observable inputs for valuations of these contracts include energy-related product prices in future years for which quoted prices in an active market exist. Valuations incorporate estimates of premiums or discounts that would be required by a market participant to arrive at an exit price, using historical market transactions adjusted for the terms of the contract. Fair value measurements were prepared by individuals with expertise in valuation techniques, pricing of energy-related products, and accounting requirements. All derivative contracts were classified as Level 2 in the fair value hierarchy as of both June 30, 2025 and December 31, 2024.

5. MARKETABLE SECURITIES
Eversource’s marketable securities include the CYAPC and YAEC legally restricted trusts that each hold equity and available-for-sale debt securities to fund the spent nuclear fuel removal obligations of their nuclear fuel storage facilities. Equity and available-for-sale debt marketable securities are recorded at fair value. CYAPC and YAEC’s spent nuclear fuel trusts are restricted and are classified in long-term Marketable Securities on the balance sheets.
Eversource’s water business also holds a trust. Securities held in this trust as of June 30, 2025 and December 31, 2024 of $4.2 million and $4.1 million, respectively, were reclassified to Assets Held for Sale on the Eversource balance sheets.
Equity Securities: Eversource's equity securities include CYAPC's and YAEC's marketable securities held in spent nuclear fuel trusts, which had fair values of $159.8 million and $163.1 million as of June 30, 2025 and December 31, 2024, respectively. Unrealized gains and losses for these spent nuclear fuel trusts are subject to regulatory accounting treatment and are recorded in Marketable Securities with the corresponding offset to long-term liabilities on the balance sheets, with no impact on the statements of income.
Available-for-Sale Debt Securities: The following is a summary of available-for-sale debt securities, which are held in CYAPC’s and YAEC’s spent nuclear fuel trusts:

| As of June 30, 2025 |  | As of December 31, 2024
Eversource (Millions of Dollars) | Amortized Cost |  | Pre-Tax Unrealized Gains |  | Pre-Tax Unrealized Losses |  | Fair Value |  | Amortized Cost |  | Pre-Tax Unrealized Gains |  | Pre-Tax Unrealized Losses |  | Fair Value

7. RATE REDUCTION BONDS AND VARIABLE INTEREST ENTITIES
Rate Reduction Bonds: In May 2018, PSNH Funding, a wholly-owned subsidiary of PSNH, issued $635.7 million of securitized RRBs in multiple tranches with a weighted average interest rate of 3.66 percent, and final maturity dates ranging from 2026 to 2035. The RRBs are expected to be repaid by February 1, 2033. RRB payments consist of principal and interest and are paid semi-annually, beginning on February 1, 2019. The RRBs were issued pursuant to a finance order issued by the NHPUC in January 2018 to recover remaining costs resulting from the divestiture of PSNH’s generation assets.
PSNH Funding was formed solely to issue RRBs to finance PSNH's unrecovered remaining costs associated with the divestiture of its generation assets. PSNH Funding is considered a VIE primarily because the equity capitalization is insufficient to support its operations. PSNH has the power to direct the significant activities of the VIE and is most closely associated with the VIE as compared to other interest holders. Therefore, PSNH is considered the primary beneficiary and consolidates PSNH Funding in its consolidated financial statements.
The following tables summarize the impact of PSNH Funding on PSNH's balance sheets and income statements:

(Millions of Dollars) |  |  |
PSNH Balance Sheets: | As of June 30, 2025 |  | As of December 31, 2024

8. PENSION BENEFITS AND POSTRETIREMENT BENEFITS OTHER THAN PENSION
Eversource provides defined benefit retirement plans (Pension Plans) that cover eligible employees. In addition to the Pension Plans, Eversource maintains non-qualified defined benefit retirement plans (SERP Plans), which provide benefits in excess of Internal Revenue Code limitations to eligible participants consisting of current and retired employees. Eversource also provides defined benefit postretirement plans (PBOP Plans) that provide life insurance and a health reimbursement arrangement created for the purpose of reimbursing retirees and dependents for health insurance premiums and certain medical expenses to eligible employees that meet certain age and service eligibility requirements.
The components of net periodic benefit plan expense/(income) for the Pension, SERP and PBOP Plans, prior to amounts capitalized as Property, Plant and Equipment or deferred as regulatory assets/(liabilities) for future recovery or refund, are shown below. The service cost component of net periodic benefit plan expense/(income), less the capitalized portion, is included in Operations and Maintenance expense on the statements of income. The remaining components of net periodic benefit plan expense/(income), less the deferred portion, are included in Other Income, Net on the statements of income. Pension, SERP and PBOP expense/(income) reflected in the statements of cash flows for CL&P, NSTAR Electric and PSNH does not include intercompany allocations of net periodic benefit plan expense/(income), as these amounts are cash settled on a short-term basis.
In August 2024, Eversource communicated to its employees participating in the Eversource 401k Plan enhanced defined contribution feature (referred to as K-Vantage) that effective January 1, 2025, a Cash Balance Pension Plan is established, which replaces employer K-Vantage contributions. Eversource transferred into the Cash Balance Pension Plan employees who are participants in the K-Vantage plan, with the exception of one union group that voted to enter effective January 1, 2026, and will credit employees a set percentage of an employee’s eligible pay based on age and years of service on the employee’s behalf. This benefit is a new, additional obligation of the existing Pension Plan and will be funded through the existing assets of the Eversource Pension Plan. The liability began accruing benefits upon the effective date of January 1, 2025.

9. COMMITMENTS AND CONTINGENCIES
A. Environmental Matters
Eversource, CL&P, NSTAR Electric and PSNH are subject to environmental laws and regulations intended to mitigate or remove the effect of past operations and improve or maintain the quality of the environment. These laws and regulations require the removal or the remedy of the effect on the environment of the disposal or release of certain specified hazardous substances at current and former operating sites. Eversource, CL&P, NSTAR Electric and PSNH have an active environmental auditing and training program and each believes it is substantially in compliance with all enacted laws and regulations.
The number of environmental sites and related reserves for which remediation or long-term monitoring, preliminary site work or site assessment is being performed are as follows:

| As of June 30, 2025 |  | As of December 31, 2024
| Number of Sites |  | Reserve (in millions) |  | Number of Sites |  | Reserve (in millions)
Eversource | 65 |  |  | $ | 152.2 |  |  | 65 |  |  | $ | 128.0 |
CL&P | 15 |  |  | 13.8 |  |  | 15 |  |  | 13.4 |
NSTAR Electric | 14 |  |  | 8.3 |  |  | 14 |  |  | 6.6 |
PSNH | 8 |  |  | 9.1 |  |  | 8 |  |  | 6.3 |

The increase in the reserve balance was due primarily to changes in cost estimates at MGP sites, primarily at NSTAR Gas and Yankee Gas.
Included in the number of sites and reserve amounts above are former MGP sites that were operated several decades ago and manufactured natural gas from coal and other processes, which resulted in certain by-products remaining in the environment that may pose a potential risk to human health and the environment, for which Eversource may have potential liability. Eversource’s reserve balances related to these former MGP sites were $139.1 million and $115.9 million as of June 30, 2025 and December 31, 2024, respectively, and related primarily to the natural gas business segment.
These reserve estimates are subjective in nature as they take into consideration several different remediation options at each specific site. The reliability and precision of these estimates can be affected by several factors, including new information concerning either the level of contamination at the site, the extent of Eversource's, CL&P's, NSTAR Electric's and PSNH's responsibility for remediation or the extent of remediation required, recently enacted laws and regulations or changes in cost estimates due to certain economic factors. It is possible that new information or future developments could require a reassessment of the potential exposure to required environmental remediation. As this information becomes available, management will continue to assess the potential exposure and adjust the reserves accordingly.
B. Guarantees and Indemnifications
In the normal course of business, Eversource parent provides credit assurances on behalf of its subsidiaries, including CL&P, NSTAR Electric and PSNH, in the form of guarantees. Management does not anticipate a material impact to net income or cash flows as a result of these various guarantees and indemnifications.
Guarantees issued on behalf of unconsolidated entities, including equity method ownership interests, for which Eversource parent is the guarantor, are recorded at fair value as a liability on the balance sheet at the inception of the guarantee. The fair value of guarantees issued on behalf of unconsolidated entities are recorded within Other Long-Term Liabilities on the balance sheet, and were $0.9 million and $1.2 million as of June 30, 2025 and December 31, 2024, respectively. Eversource regularly reviews performance risk under these guarantee arrangements, and believes the likelihood of payments being required under the guarantees is remote. In the event it becomes probable that Eversource parent will be required to perform under the guarantee, the amount of probable payment will be recorded.

On September 30, 2024, Eversource completed the sale of its 50 percent ownership share in the South Fork Wind and Revolution Wind projects to GIP. Under the agreement with Global Infrastructure Partners (GIP), Eversource’s existing and certain additional credit support obligations for Revolution Wind are expected to roll off as the project completes construction. On July 9, 2024, Eversource completed the sale of its 50 percent ownership share of Sunrise Wind to Ørsted. Under the agreement with Ørsted, Eversource’s existing credit support obligations for Sunrise Wind were either terminated or indemnified by Ørsted as a result of the sale.
The following table summarizes Eversource parent's exposure to guarantees and indemnifications of its subsidiaries and affiliates to external parties, and primarily relates to its previously-owned offshore wind projects:

As of June 30, 2025

C. FERC ROE Complaints
Four separate complaints were filed at the FERC by combinations of New England state attorneys general, state regulatory commissions, consumer advocates, consumer groups, municipal parties and other parties (collectively, the Complainants). In each of the first three complaints, filed on October 1, 2011, December 27, 2012, and July 31, 2014, respectively, the Complainants challenged the NETOs' base ROE of 11.14 percent that had been utilized since 2005 and sought an order to reduce it prospectively from the date of the final FERC order and for the separate 15-month complaint periods. In the fourth complaint, filed April 29, 2016, the Complainants challenged the NETOs' base ROE billed of 10.57 percent and the maximum ROE for transmission incentive (incentive cap) of 11.74 percent, asserting that these ROEs were unjust and unreasonable.
The ROE originally billed during the period October 1, 2011 (beginning of the first complaint period) through October 15, 2014 consisted of a base ROE of 11.14 percent and incentives up to 13.1 percent. On October 16, 2014, FERC issued Opinion No. 531-A and set the base ROE at 10.57 percent and the incentive cap at 11.74 percent for the first complaint period. This was also effective for all prospective billings to customers beginning October 16, 2014. This FERC order was vacated on April 14, 2017 by the U.S. Court of Appeals for the D.C. Circuit (the Court).
All amounts associated with the first complaint period have been refunded, which totaled $38.9 million (pre-tax and excluding interest) at Eversource and reflected both the base ROE and incentive cap prescribed by the FERC order. The refund consisted of $22.4 million for CL&P, $13.7 million for NSTAR Electric and $2.8 million for PSNH.
Eversource has recorded a reserve of $39.1 million (pre-tax and excluding interest) for the second complaint period as of both June 30, 2025 and December 31, 2024. This reserve represents the difference between the billed rates during the second complaint period and a 10.57 percent base ROE and 11.74 percent incentive cap. The reserve consisted of $21.4 million for CL&P, $14.6 million for NSTAR Electric and $3.1 million for PSNH as of both June 30, 2025 and December 31, 2024.
On October 16, 2018, FERC issued an order on all four complaints describing how it intends to address the issues that were remanded by the Court. FERC proposed a new framework to determine (1) whether an existing ROE is unjust and unreasonable and, if so, (2) how to calculate a replacement ROE. Initial briefs were filed by the NETOs, Complainants and FERC Trial Staff on January 11, 2019 and reply briefs were filed on March 8, 2019. The NETOs' brief was supportive of the overall ROE methodology determined in the October 16, 2018 order provided the FERC does not change the proposed methodology or alter its implementation in a manner that has a material impact on the results.
The FERC order included illustrative calculations for the first complaint using FERC's proposed frameworks with financial data from that complaint. Those illustrative calculations indicated that for the first complaint period, for the NETOs, which FERC concludes are of average financial risk, the preliminary just and reasonable base ROE is 10.41 percent and the preliminary incentive cap on total ROE is 13.08 percent.
If the results of the illustrative calculations were included in a final FERC order for each of the complaint periods, then a 10.41 percent base ROE and a 13.08 percent incentive cap would not have a significant impact on our financial statements for all of the complaint periods. These preliminary calculations are not binding and do not represent what we believe to be the most likely outcome of a final FERC order.
On November 21, 2019, FERC issued Opinion No. 569 affecting the two pending transmission ROE complaints against the Midcontinent ISO (MISO) transmission owners, in which FERC adopted a new methodology for determining base ROEs. Various parties sought rehearing. On December 23, 2019, the NETOs filed supplementary materials in the NETOs' four pending cases to respond to this new methodology because of the uncertainty of the applicability to the NETOs' cases. On May 21, 2020, the FERC issued its order in Opinion No. 569-A on the rehearing of the MISO transmission owners' cases, in which FERC again changed its methodology for determining the MISO transmission owners' base ROEs. On November 19, 2020, the FERC issued Opinion No. 569-B denying rehearing of Opinion No. 569-A and reaffirmed the methodology previously adopted in Opinion No. 569-A. The new methodology differs significantly from the methodology proposed by FERC in its October 16, 2018 order to determine the NETOs' base ROEs in their four pending cases. FERC Opinion Nos. 569-A and 569-B were appealed to the Court. On August 9, 2022, the Court issued its decision vacating MISO ROE FERC Opinion Nos. 569, 569-A and 569-B and remanded to FERC to reopen the proceedings. The Court found that FERC’s development of the new return methodology was arbitrary and capricious due to FERC’s failure to offer a reasonable explanation for its decision to reintroduce the risk-premium financial model in its new methodology for calculating a just and reasonable return.
On October 17, 2024, FERC issued an order on the remand of the MISO ROE proceedings. The order addressed the Court’s decision that the reintroduction of the risk-premium financial model in the ROE methodology was arbitrary and capricious by removing the risk-premium financial model from the ROE methodology. The removal of the risk-premium financial model was the only revision to FERC’s ROE methodology and resulted in a two-model approach utilizing the two-step discounted cash flow model and the capital asset pricing model. MISO transmission owners were directed to provide refunds for the period November 12, 2013 to February 11, 2015 (the first MISO ROE complaint refund period) and for the period from September 28, 2016 (the date of FERC’s order on the first MISO ROE complaint) to October 17, 2024 by December 1, 2025. The order also stated that FERC does not preclude the use of the risk-premium financial model in future proceedings if the parties can demonstrate that FERC’s stated concerns around the inclusion of the model have been addressed. On March 25, 2025, FERC issued an order addressing arguments raised on rehearing, sustaining the result, and denying rehearing.
On November 13, 2024, the NETOs filed a supplemental brief in their four pending ROE proceedings to explain to FERC that it cannot apply the reasoning and methodologies of the MISO ROE case to the NETOs’ cases due to the entirely different set of facts in the MISO and NETOs ROE proceedings. Doing so would violate the substance of the Court’s April 14, 2017 order and would violate the legal standard required by the Federal Power Act.
30

On February 4, 2025, the MISO transmission owners submitted a petition for review with the Court requesting review of the October 17, 2024 MISO ROE order on remand and a December 19, 2024 notice of denial of rehearing. The petition requests review of FERC’s decision to retroactively backdate the MISO transmission owners’ base ROE to the date of an earlier order that FERC abandoned when it issued Order No. 569, treat an underlying unlawful complaint as if it were legitimate, and order eight years of interest as part of the directed refunds. On July 11, 2025, the Court issued an order on the briefing schedule with initial briefs due August 14, 2025 and final briefs due January 26, 2026.
Given the significant uncertainty regarding the applicability of the FERC order in the MISO transmission owners’ two complaint cases to the NETOs’ pending four complaint cases due to the complex differences between the cases, Eversource concluded that there is no reasonable basis for a change to the reserve or recognized ROEs for any of the complaints or subsequent periods at this time and Eversource cannot reasonably estimate any potential range of loss for any of the four complaint proceedings at this time. The resolution of these proceedings could have a material impact on the financial condition, results of operations and cash flows.
Eversource, CL&P, NSTAR Electric and PSNH currently record revenues at the 10.57 percent base ROE and incentive cap at 11.74 percent established in the October 16, 2014 FERC order.
A change of 10 basis points to the base ROE used to establish the reserves would impact Eversource’s after-tax earnings by an average of approximately $3 million for each of the four 15-month complaint periods.
D. Offshore Wind Contingent Liability
On September 30, 2024, Eversource completed the sale of its 50 percent ownership share in the South Fork Wind and Revolution Wind projects to GIP for adjusted gross proceeds of $745 million, which were received at closing. As part of the sale, Eversource and GIP agreed to make certain post-closing purchase price adjustment payments, which could impact the final purchase price. The post-closing purchase price adjustment payments include cost sharing obligations that require Eversource to share equally with GIP in GIP’s funding obligations up to an effective cap of approximately $240 million of incremental capital expenditure overruns incurred during the construction phase for Revolution Wind, after which Eversource will have responsibility for GIP’s obligations for any additional capital expenditure overruns in excess of this amount. The purchase price is also subject to post-closing adjustments as a result of final project economics, which includes Eversource’s obligation to maintain GIP’s internal rate of return through the construction period for each project as specified in the agreement. For Revolution Wind, purchase price adjustment payments are expected to be completed no later than late 2026. South Fork Wind has achieved commercial operation, and Eversource made the construction cost post-close purchase price adjustment payment related to this project of $69 million in June 2025. As permitted within the terms of the agreement, Eversource has disputed a significant portion of this equalization payment related to project contingencies and expects resolution by the end of the year.
Upon closing of the sale, Eversource recorded a contingent liability of $365 million, reflecting its estimate of the future obligations under the terms of the sale to GIP, which include the expected cost overrun sharing obligation, expected obligation to maintain GIP’s internal rate of return, and obligation for other future costs. As of June 30, 2025 and December 31, 2024, the contingent liability was $296 million and $365 million, respectively, and is recorded in Other Current Liabilities and Other Long-Term Liabilities on Eversource’s balance sheets.
Contingencies are evaluated using the best information available at the time the financial statements are published, and this assessment involves judgments and assumptions about future events. Factors that could increase the post-closing adjustment payments owed to GIP include construction cost overruns for Revolution Wind as well as the extent of construction delays, which would impact the economics associated with the purchase price adjustment, and the eligibility for federal investment tax credits for Revolution Wind at a lower value than assumed and included in the purchase price.
The purchase price of Revolution Wind included the sales value related to a 40 percent level of federal investment tax credits. A change in the expected value or qualification of ITC adders could result in a significant loss in a future period.
New information or future developments that arise as the construction of Revolution Wind progresses, and as cost estimates are received, reviewed and revised, as well as schedule updates, will necessitate a reassessment of the estimated liability related to post-closing adjustment payments. The Company reviews available projections of total construction costs, including the latest cost estimates and project timeline. As construction continues to progress, the construction of the offshore substation and turbine tower installations may lead to future cost overruns. The Company has factored known cost overruns into the existing liability estimate. Based on the status of construction and latest cost projections, management has determined that the information currently available does not necessitate a change to the Company’s existing liability estimate. It is possible that as additional updated cost estimates become available and if those future cost overruns materialize, or other adverse changes in facts, regulations and circumstances occur, it could result in additional losses and increases to this liability, which could be material. The Company believes it is reasonably possible that there could be an additional loss in excess of the liability recorded, but management cannot reasonably estimate a range of loss beyond the amount recorded at this time. The Company will continue to monitor developments, evaluate potential exposures, and revise its estimates as additional information becomes available.
Total net proceeds could also be adjusted for a benefit due to Eversource if there are lower operation costs or higher availability of the projects through the period that is four years following the commercial operation of Revolution Wind.

E. Leases
In the first quarter of 2025, EGMA entered into a land and building finance lease that is expected to commence late 2025. The lease contains a purchase option that the Company has determined is probable of being executed. In accordance with ASC 842, Leases, the Company will recognize the right-of-use asset and corresponding lease liability, and will assess the purchase option as part of the lease fair value upon commencement. As of June 30, 2025, the lease agreement totaled $18.7 million and the estimated purchase option was $19.0 million.

PSNH | $ | 1 |  |  | 100,000,000 |  |  | 301 |  |  | 301 |

Common Share Issuances: On May 30, 2025, Eversource entered into an equity distribution agreement pursuant to which it may offer and sell up to $1.2 billion of its common shares from time to time through an “at-the-market” (ATM) equity offering program. Eversource may issue and sell its common shares through its sales agents during the term of this agreement. Shares may be offered in transactions on the New York Stock Exchange, in the over-the-counter market, through negotiated transactions or otherwise. Sales may be made at either market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices. In the second quarter of 2025, Eversource issued 3,378,765 common shares, which resulted in proceeds of $218.0 million, net of issuance costs. Eversource used the net proceeds received for general corporate purposes.
On May 11, 2022, Eversource entered into an equity distribution agreement pursuant to which it could offer and sell up to $1.2 billion of its common shares from time to time through an ATM equity offering program. In the first six months of 2024, Eversource issued 4,206,649 common shares, which resulted in proceeds of $248.2 million, net of issuance costs. Eversource used the net proceeds received for general corporate purposes. Eversource completed this program in October 2024.
Treasury Shares: As of June 30, 2025 and December 31, 2024, there were 8,064,521 and 9,116,315 Eversource common shares held as treasury shares, respectively. As of June 30, 2025 and December 31, 2024, there we re 371,038,611 and 366,608,052 Eversource common shares outstanding, respectively.
Eversource issues treasury shares to satisfy awards under the Company's incentive plans, shares issued under the dividend reinvestment and share purchase plan, and matching contributions under the Eversource 401k Plan. The issuance of treasury shares represents a non-cash transaction, as the treasury shares were used to fulfill Eversource's obligations that require the issuance of common shares.
13. COMMON SHAREHOLDERS' EQUITY AND NONCONTROLLING INTERESTS
Dividends on the preferred stock of CL&P and NSTAR Electric totaled $1.9 million for each of the three months ended June 30, 2025 and 2024 and $3.8 million for each of the six months ended June 30, 2025 and 2024. These dividends were presented as Net Income Attributable to Noncontrolling Interests on the Eversource statements of income. Noncontrolling Interest – Preferred Stock of Subsidiaries on the Eversource balance sheets totaled $155.6 million as of June 30, 2025 and December 31, 2024. On the Eversource balance sheets, Common Shareholders' Equity was fully attributable to Eversource parent and Noncontrolling Interest – Preferred Stock of Subsidiaries was fully attributable to the noncontrolling interest.
14. EARNINGS PER SHARE
Basic earnings per share is computed based upon the weighted average number of common shares outstanding during each period. Diluted earnings per share is computed on the basis of the weighted average number of common shares outstanding plus the potential dilutive effect of certain share-based compensation awards as if they were converted into outstanding common shares. The dilutive effect of unvested RSU and performance share awards is calculated using the treasury stock method. RSU and performance share awards are included in basic weighted average common shares outstanding as of the date that all necessary vesting conditions have been satisfied. For the three and six months ended June 30, 2025 and 2024, there were no antidilutive share awards excluded from the computation of diluted EPS.
The following table sets forth the components of basic and diluted earnings per share:

Eversource (Millions of Dollars, except share information) | For the Three Months Ended |  | For the Six Months Ended

16. SEGMENT INFORMATION
Eversource is organized into the Electric Distribution, Electric Transmission, Natural Gas Distribution and Water Distribution reportable segments and Other based on a combination of factors, including the characteristics of each segments' services, the sources of operating revenues and expenses and the regulatory environment in which each segment operates. The Electric Distribution segment consists of the rate-regulated distribution businesses of CL&P, NSTAR Electric and PSNH, and includes the results of NSTAR Electric's solar power facilities. The Electric Transmission segment consists of the rate-regulated electric transmission businesses of CL&P, NSTAR Electric and PSNH. The Natural Gas Distribution segment consists of the rate-regulated businesses of Yankee Gas, NSTAR Gas and EGMA. The Water Distribution segment consists of the rate-regulated business of Aquarion. These reportable segments represent substantially all of Eversource's total consolidated revenues. Revenues from the sale of electricity, natural gas and water primarily are derived from residential, commercial and industrial customers and are not dependent on any single customer.
Eversource's reportable segments are determined based upon the level at which Eversource's chief operating decision maker assesses performance and makes decisions about the allocation of company resources. The chief operating decision maker uses the net income of each reportable segment to evaluate return generated from assets and decide how to reinvest profits and allocate resources, to monitor budget-to-actual results, in the planning and forecasting process, in determining compensation achievement, and in benchmarking to Eversource’s peers. Eversource’s chief operating decision maker is its chief executive officer. The accounting policies of the segments are the same as those described in the summary of significant accounting policies.
The remainder of Eversource's operations is presented as Other in the tables below and primarily consists of 1) the equity in earnings of Eversource parent from its subsidiaries and intercompany interest income, both of which are eliminated in consolidation, and interest expense related to the debt of Eversource parent, 2) the revenues and expenses of Eversource Service, most of which are eliminated in consolidation, 3) the operations of CYAPC and YAEC, 4) the results of other unregulated subsidiaries, which are not part of its core business, and 5) Eversource's equity ownership interests that are not consolidated, which primarily included the offshore wind investments until sale of the three offshore wind projects in the third quarter of 2024 and a natural gas pipeline owned by Enbridge, Inc.
In the ordinary course of business, Yankee Gas, NSTAR Gas and EGMA purchase natural gas transmission services from the Enbridge, Inc. natural gas pipeline project described above. These affiliate transaction costs total $77.7 million annually and are classified as Purchased Power, Purchased Natural Gas and Transmission on the Eversource statements of income.
Each of Eversource's subsidiaries, including CL&P, NSTAR Electric and PSNH, has one reportable segment.
Cash flows used for investments in plant included in the segment information below are cash capital expenditures that do not include amounts incurred on capital projects but not yet paid, cost of removal, AFUDC related to equity funds, and the capitalized and deferred portions of pension and PBOP income/expense.

(1) The significant expense categories and amounts align with the segment-level information that is regularly provided to the chief operating decision maker. Costs of the operations organization include labor and overtime, outside services, vehicles, vegetation management, employee expenses, fees and payments, regulatory assessments, and materials, partially offset by reimbursements. Corporate shared services include corporate centralized functions. Costs within these corporate functions primarily include labor, services by vendors, fees and payments, insurance, and regulatory assessments. Other includes information technology system depreciation at Eversource Service charged to the operating businesses, as well as storm funding, capitalization and various other corporate costs. The segment-level operating expense for information technology system depreciation is eliminated and reflected in depreciation in Eversource’s consolidation.
For the water distribution segment, the chief operating decision maker is provided with total operations and maintenance expense information to manage its operations. Operations and maintenance expenses primarily include employee costs, benefits, and outside services.
38

(2) Other segment line items for the electric distribution, electric transmission and natural gas distribution segments primarily include purchased power, purchased natural gas and transmission, taxes other than income taxes including property, payroll-related and Connecticut gross earnings taxes, and energy efficiency program expenses. Other segment line items for the water distribution business primarily include taxes other than income taxes.
The following table summarizes Eversource's segmented total assets:

Eversource (Millions of Dollars) | Electric Distribution |  | Natural Gas Distribution |  | Electric Transmission |  | Water Distribution |  | Other |  | Eliminations |  | Total
As of June 30, 2025 | $ | 32,973.2 |  |  | $ | 10,092.5 |  |  | $ | 16,679.4 |  |  | $ | 2,568.4 |  |  | $ | 28,405.2 |  |  | $ | (29,762.6) |  |  | $ | 60,956.1 |

17. ASSETS HELD FOR SALE
On January 27, 2025, Eversource entered into a definitive agreement to sell the Aquarion water distribution business. Subject to certain closing adjustments, the aggregate enterprise value of the sale is approximately $2.4 billion in cash, which includes approximately $1.6 billion for the equity and $800 million of net debt that will be extinguished at closing. The sale is subject to approval by PURA, DPU and the NHPUC, as well as other approvals pursuant to the Hart-Scott-Rodino Antitrust Improvements Act, for which the relevant waiting period has expired, as well as other customary closing conditions. The sale is expected to close in late 2025. Eversource plans to use the net proceeds from the pending sale to pay down Eversource parent debt.
The assets and liabilities of the Aquarion water distribution business met the criteria to be classified as held for sale and have been classified separately as current or long-term assets and liabilities held for sale on the Eversource balance sheets as of June 30, 2025 and December 31, 2024. As Eversource concluded this is the sale of a business, all goodwill held by the water distribution reporting unit was included in the carrying amount of the business and is also classified within assets held for sale. Long-term debt will be repaid by Eversource upon closing and is therefore excluded from liabilities held for sale. Assets and liabilities classified as held for sale are measured at the lower of carrying amount or fair value less costs to sell. The water distribution business did not and will not meet the criteria to be presented as a discontinued operation.
The major classes of Aquarion’s assets and liabilities presented in current and long-term Assets Held for Sale and Liabilities Held for Sale on the Eversource balance sheets, which are included in the Water Distribution reportable segment, were as follows:

(Millions of Dollars) | As of June 30, 2025 |  | As of December 31, 2024
Restricted Cash | $ | 5.9 |  |  | $ | 5.8 |
Receivables, Net | 19.3 |  |  | 14.4 |
Unbilled Revenues | 11.2 |  |  | 11.5 |
Prepayments and Other Current Assets | 20.4 |  |  | 24.6 |
Total Current Assets Held for Sale | $ | 56.8 |  |  | $ | 56.3 |
Property, Plant and Equipment, Net | $ | 1,934.8 |  |  | $ | 1,885.2 |
Regulatory Assets | 47.9 |  |  | 51.2 |
Goodwill | 662.4 |  |  | 662.5 |
Other Long-Term Assets | 16.5 |  |  | 12.2 |
Total Long-Term Assets Held for Sale | $ | 2,661.6 |  |  | $ | 2,611.1 |
Accounts Payable | $ | 27.6 |  |  | $ | 24.2 |
Other Current Liabilities | 31.3 |  |  | 28.4 |
Total Current Liabilities Held for Sale | $ | 58.9 |  |  | $ | 52.6 |
Regulatory Liabilities | $ | 128.4 |  |  | $ | 132.2 |
Other Long-Term Liabilities | 270.7 |  |  | 266.7 |
Total Long-Term Liabilities Held for Sale | $ | 399.1 |  |  | $ | 398.9 |

For the three months ended June 30, 2025 and 2024, pre-tax income associated with the held for sale water distribution business was $13.0 million and $6.7 million, respectively. For the six months ended June 30, 2025 and 2024, pre-tax income associated with the held for sale water distribution business was $15.5 million and $14.4 million, respectively.

EVERSOURCE ENERGY AND SUBSIDIARIES
Management's Discussion and Analysis of Financial Condition and Results of Operations
The following discussion and analysis should be read in conjunction with our unaudited condensed consolidated financial statements and related combined notes included in this combined Quarterly Report on Form 10-Q, the combined Quarterly Report on Form 10-Q for the quarter ended March 31, 2025, as well as the Eversource 2024 combined Annual Report on Form 10-K. References in this combined Quarterly Report on Form 10-Q to "Eversource," the "Company," "we," "us," and "our" refer to Eversource Energy and its consolidated subsidiaries. All per-share amounts are reported on a diluted basis. The unaudited condensed consolidated financial statements of Eversource, NSTAR Electric and PSNH and the unaudited condensed financial statements of CL&P are herein collectively referred to as the "financial statements."
Refer to the Glossary of Terms included in this combined Quarterly Report on Form 10-Q for abbreviations and acronyms used throughout this Management's Discussion and Analysis of Financial Condition and Results of Operations.
The only common equity securities that are publicly traded are common shares of Eversource. Our second quarter and first half of 2025 and 2024 earnings discussion includes a financial measure, EPS by business, that is not recognized under GAAP (non-GAAP), and is calculated by dividing the Net Income Attributable to Common Shareholders of each business by the weighted average diluted Eversource common shares outstanding for the period. The earnings and EPS of each business do not represent a direct legal interest in the assets and liabilities of such business, but rather represent a direct interest in our assets and liabilities as a whole. Full year 2024 earnings discussion includes a non-GAAP financial measure referencing earnings and EPS excluding a loss on the sales of the offshore wind equity method investments and a loss on the pending sale of the Aquarion water distribution business.
We use these non-GAAP financial measures to evaluate and provide details of earnings results by business and to more fully compare and explain our results without including these items. This information is among the primary indicators we use as a basis for evaluating performance and planning and forecasting of future periods. We believe the impacts of the loss on the offshore wind equity method investments and the loss on the pending sale of the Aquarion water distribution business are not indicative of our ongoing costs and performance. We view these charges as not directly related to the ongoing operations of the business and therefore not an indicator of baseline operating performance. Due to the nature and significance of the effect of these items on Net Income Attributable to Common Shareholders and EPS, we believe that the non-GAAP presentation is a more meaningful representation of our financial performance and provides additional and useful information to readers of this report in analyzing historical and future performance of our business. These non-GAAP financial measures should not be considered as alternatives to reported Net Income Attributable to Common Shareholders or EPS determined in accordance with GAAP as indicators of operating performance.
We make statements concerning our expectations, beliefs, plans, objectives, goals, strategies, assumptions of future events, future financial performance or growth and other statements that are not historical facts. These statements are "forward-looking statements" within the meaning of U.S. federal securities laws. You can generally identify our forward-looking statements through the use of words or phrases such as "estimate," "expect," "pending," "anticipate," "intend," "plan," "project," "believe," "forecast," "would," "should," "could," and other similar expressions. Forward-looking statements involve risks and uncertainties that may cause actual results or outcomes to differ materially from those included in our forward-looking statements. Forward-looking statements are based on the current expectations, estimates, assumptions or projections of management and are not guarantees of future performance. These expectations, estimates, assumptions or projections may vary materially from actual results. Accordingly, any such statements are qualified in their entirety by reference to, and are accompanied by, the following important factors that may cause our actual results or outcomes to differ materially from those contained in our forward-looking statements, including, but not limited to:
• cyberattacks or breaches, including those resulting in the compromise of the confidentiality of our proprietary information and the personal information of our customers,
• the ability to qualify for investment tax credits and investment tax credit adders,
• variability in the costs and final investment returns of the Revolution Wind offshore wind project as it relates to the purchase price post-closing adjustment under the terms of the sale agreement for the project,
• disruptions in the capital markets or other events that make our access to necessary capital more difficult or costly,
• changes in economic conditions, including impact on interest rates, tax policies, tariffs, and customer demand and payment ability,
• ability or inability to commence and complete our major strategic development projects and opportunities,
• acts of war or terrorism, physical attacks or grid disturbances that may damage and disrupt our electric transmission and electric, natural gas, and water distribution systems,
• actions or inaction of local, state and federal regulatory, public policy and taxing bodies,
• substandard performance of third-party suppliers and service providers,
• fluctuations in weather patterns, including extreme weather due to climate change,
• changes in business conditions, which could include disruptive technology or development of alternative energy sources related to our current or future business model,
• contamination of, or disruption in, our water supplies,
• changes in levels or timing of capital expenditures,
• changes in laws, regulations, Presidential executive orders or regulatory policy, including compliance with environmental laws and regulations,
• changes in accounting standards and financial reporting regulations,
• actions of rating agencies, and
• other presently unknown or unforeseen factors.

Other risk factors are detailed in our reports filed with the SEC and are updated as necessary and available on our website at www.eversource.com and on the SEC’s website at www.sec.gov, and we encourage you to consult such disclosures.
All such factors are difficult to predict and contain uncertainties that may materially affect our actual results, many of which are beyond our control. You should not place undue reliance on the forward-looking statements, as each speaks only as of the date on which such statement is made, and, except as required by federal securities laws, we undertake no obligation to update any forward-looking statement or statements to reflect events or circumstances after the date on which such statement is made or to reflect the occurrence of unanticipated events. New factors emerge from time to time and it is not possible for us to predict all of such factors, nor can we assess the impact of each such factor on the business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. For more information, see Item 1A, Risk Factors, included in this combined Quarterly Report on Form 10-Q and in Eversource's 2024 combined Annual Report on Form 10-K. This combined Quarterly Report on Form 10-Q and Eversource's 2024 combined Annual Report on Form 10-K also describe material contingencies and critical accounting policies in the accompanying Management's Discussion and Analysis of Financial Condition and Results of Operations and Combined Notes to Financial Statements. We encourage you to review these items.

Our electric distribution segment earnings increased $11.8 million and $32.1 million in the second quarter and the first half of 2025, respectively, as compared to the second quarter and first half of 2024, due primarily to higher revenues from base distribution rate increases at PSNH effective August 1, 2024 and at NSTAR Electric effective January 1, 2025 and from CL&P's capital tracking mechanism due to increased electric system improvements. Those earnings increases were partially offset by higher property tax expense, higher interest expense, higher depreciation expense, lower net interest income on regulatory deferrals, and higher operations and maintenance expense.
Our electric transmission segment earnings increased $19.0 million and $41.8 million in the second quarter and the first half of 2025, respectively, as compared to the second quarter and the first half of 2024, due primarily to a higher transmission rate base as a result of our continued investment in our transmission infrastructure and lower interest expense.
Our natural gas distribution segment earnings increased $8.2 million and $36.1 million in the second quarter and the first half of 2025, respectively, as compared to the second quarter and the first half of 2024, due primarily to higher revenues from base distribution rate increases effective November 1, 2024 at EGMA and at NSTAR Gas and from capital tracking mechanisms due to continued investments in natural gas infrastructure. Those earnings increases were partially offset by higher operations and maintenance expense, higher interest expense, higher depreciation expense, and higher property tax expense.
Our water distribution segment earnings increased $6.4 million and $4.5 million in the second quarter and the first half of 2025, respectively, as compared to the second quarter and the first half of 2024, due primarily to higher revenues from the revenue adjustment mechanism in Connecticut and lower interest expense. Higher earnings in the first half of 2025 compared to the first half of 2024 were partially offset by the absence in 2025 of a benefit recorded in the first half of 2024 to recognize the impacts of the Aquarion Water Company of Connecticut’s rate case decision from PURA.
Eversource Parent and Other Companies: Eversource parent and other companies’ losses increased by $28.0 million and $68.2 million in the second quarter and the first half of 2025, respectively, as compared to the second quarter and the first half of 2024, due primarily to higher interest expense due to the absence in 2025 of capitalized interest as a result of the sale of our offshore wind projects in the third quarter of 2024 and higher interest costs from short-term debt.
Liquidity
Sources and Uses of Cash: Eversource’s regulated business is capital intensive and requires considerable capital resources. Eversource’s regulated companies’ capital resources are provided by cash flows generated from operations, short-term borrowings, long-term debt issuances, capital contributions from Eversource parent, and existing cash, and are used to fund their liquidity and capital requirements. Eversource’s regulated companies typically maintain minimal cash balances and use short-term borrowings to meet their working capital needs and other cash requirements. Short-term borrowings are also used as a bridge to long-term debt financings. The levels of short-term borrowing may vary significantly over the course of the year due to the impact of fluctuations in cash flows from operations (including timing of storm costs and regulatory recoveries), dividends paid, capital contributions received and the timing of long-term debt financings.
42

Eversource, CL&P, NSTAR Electric and PSNH each uses its available capital resources to fund its respective construction expenditures, meet debt requirements, pay operating costs, including storm-related costs, pay dividends, and fund corporate obligations. Eversource's regulated companies recover their electric, natural gas and water distribution construction expenditures as the related project costs are depreciated over the life of the assets. This impacts the timing of the revenue stream designed to fully recover the total investment including a return on the equity and debt used to finance the investments. Eversource's regulated companies spend a significant amount of cash on capital improvements and construction projects that have a long-term return on investment and recovery period.
We expect the future operating cash flows of Eversource, CL&P, NSTAR Electric and PSNH, along with our existing borrowing availability and access to both debt and equity markets, will be sufficient to meet any working capital and future operating requirements, and capital investment forecasted opportunities.
Eversource is currently in the process of selling its Aquarion water distribution business. For information regarding the pending sale and expected use of proceeds, see “Business Development and Capital Expenditures - Pending Sale of Aquarion” included in this Management’s Discussion and Analysis of Financial Condition and Results of Operations.
Cash and cash equivalents totaled $343.7 million as of June 30, 2025, compared with $26.7 million as of December 31, 2024.
Short-Term Debt - Commercial Paper Programs and Credit Agreements: Eversource parent has a $2.00 billion commercial paper program allowing Eversource parent to issue commercial paper as a form of short-term debt. Eversource parent, CL&P, PSNH, NSTAR Gas, Yankee Gas, EGMA and Aquarion Water Company of Connecticut are parties to a five-year $2.00 billion revolving credit facility, which terminates on October 11, 2029. This revolving credit facility serves to backstop Eversource parent's $2.00 billion commercial paper program.
NSTAR Electric has a $650.0 million commercial paper program allowing NSTAR Electric to issue commercial paper as a form of short-term debt. NSTAR Electric is also a party to a five-year $650.0 million revolving credit facility, which terminates on October 11, 2029, that serves to backstop NSTAR Electric's $650.0 million commercial paper program.
The amount of borrowings outstanding and available under the commercial paper programs were as follows:

| Borrowings Outstanding as of |  | Available Borrowing Capacity as of |  | Weighted-Average Interest Rate as of
| June 30, 2025 |  | December 31, 2024 |  | June 30, 2025 |  | December 31, 2024 |  | June 30, 2025 |  | December 31, 2024
(Millions of Dollars) |  |  |  |  |
Eversource Parent Commercial Paper Program | $ | 950.5 |  |  | $ | 1,538.0 |  |  | $ | 1,049.5 |  |  | $ | 462.0 |  |  | 4.78 | % |  | 4.76 | %
NSTAR Electric Commercial Paper Program | 430.0 |  |  | 504.8 |  |  | 220.0 |  |  | 145.2 |  |  | 4.57 | % |  | 4.55 | %

There were no borrowings outstanding on the revolving credit facilities as of June 30, 2025 and December 31, 2024.
CL&P and PSNH have uncommitted line of credit agreements totaling $375 million and $250 million, respectively, all of which will expire in either September 2025, October 2025 or May 2026. There are no borrowings outstanding on either the CL&P or PSNH uncommitted line of credit agreements as of June 30, 2025 and December 31, 2024.
Amounts outstanding under the commercial paper programs are included in Notes Payable and classified in current liabilities on the Eversource and NSTAR Electric balance sheets, as all borrowings are outstanding for no more than 364 days at one time. As a result of the Yankee Gas long-term debt issuances in July 2025, $110.0 million of commercial paper borrowings under the Eversource parent commercial paper program were reclassified to Long-Term Debt on Eversource parent’s balance sheet as of June 30, 2025.
Intercompany Borrowings: Eversource parent uses its available capital resources to provide loans to its subsidiaries to assist in meeting their short-term borrowing needs. Eversource parent records intercompany interest income from its loans to subsidiaries, which is eliminated in consolidation. Intercompany loans from Eversource parent to its subsidiaries are eliminated in consolidation on Eversource's balance sheets. As of June 30, 2025 and December 31, 2024, there were intercompany loans from Eversource parent to PSNH of $35.3 million and $131.1 million, respectively. As of December 31, 2024, there were intercompany loans from Eversource parent to CL&P of $280.0 million. Eversource parent charges interest on these intercompany loans at the same weighted-average interest rate as its commercial paper program. Intercompany loans from Eversource parent are included in Notes Payable to Eversource Parent and classified in current liabilities on the respective subsidiary's balance sheets, as these intercompany borrowings are outstanding for no more than 364 days at one time.
Long-Term Debt Issuance Authorizations: On March 26, 2025, PURA approved Yankee Gas’ request for authorization to issue up to $360.0 million in long-term debt through December 31, 2026. On May 27, 2025, NHPUC approved PSNH’s request for authorization to issue up to $300.0 million in long-term debt through December 31, 2025.

Eversource Parent Series H Senior Notes | 3.15 | % |  | (300.0) |  |  | January 2025 |  | January 2025 |  | Paid at maturity
NSTAR Gas Series Y First Mortgage Bonds | 4.86 | % |  | 205.0 |  |  | June 2025 |  | June 2030 |  | Repaid short-term debt, paid capital expenditures and working capital
NSTAR Gas Series Z First Mortgage Bonds | 5.30 | % |  | 20.0 |  |  | June 2025 |  | June 2035 |  | Repaid short-term debt, paid capital expenditures and working capital
NSTAR Gas Series R First Mortgage Bonds | 2.33 | % |  | (75.0) |  |  | May 2025 |  | May 2025 |  | Paid at maturity
Yankee Gas Series Y First Mortgage Bonds | 5.02 | % |  | 148.0 |  |  | July 2025 |  | January 2031 |  | Repay Series M bonds at maturity, repaid short-term debt, paid capital expenditures and working capital
Yankee Gas Series Z First Mortgage Bonds | 5.55 | % |  | 37.0 |  |  | July 2025 |  | July 2035 |  | Repay Series M bonds at maturity, repaid short-term debt, paid capital expenditures and working capital

As a result of the Yankee Gas long-term debt issuances in July 2025, $75.0 million of current portion of long-term debt was reclassified to Long-Term Debt on Eversource parent’s balance sheet as of June 30, 2025.
Rate Reduction Bonds: PSNH's RRB payments consist of principal and interest and are paid semi-annually. PSNH paid $21.6 million of RRB principal payments and $6.9 million of interest payments in the first half of 2025, and paid $21.6 million of RRB principal payments and $7.6 million of interest payments in the first half of 2024.
Common Share Issuances and Equity Distribution Agreement: On May 30, 2025, Eversource entered into an equity distribution agreement pursuant to which it may offer and sell up to $1.2 billion of its common shares from time to time through an ATM equity offering program. In the second quarter of 2025, we issued 3,378,765 common shares, which resulted in proceeds of $218.0 million, net of issuance costs. Eversource used the net proceeds received for general corporate purposes.
Cash Flows: Cash flows from operating activities primarily result from the transmission and distribution of electricity, and the distribution of natural gas and water. Cash flows provided by operating activities totaled $2.10 billion in the first half of 2025, compared with $962.0 million in the first half of 2024. Operating cash flows were favorably impacted by an improvement in regulatory recoveries driven primarily by the timing of collections for CL&P’s non-bypassable FMCC, CL&P’s SBC, and other regulatory tracking mechanisms. The CL&P non-bypassable FMCC retail rate increased as a result of the 2024 RAM decision and the net Millstone and Seabrook contract cash flows were higher in 2025 as compared to 2024. These higher collections resulted in an improvement to operating cash flows of $501.1 million for the six month period. The impacts of regulatory collections are included in both Regulatory Recoveries and Amortization on the statements of cash flows. Operating cash flows were also favorably impacted by a decrease of $200.4 million in cash payments to vendors for storm costs and the timing of cash collections on our accounts receivable. These favorable impacts were partially offset by the timing of cash payments made on our accounts payable, an increase in cost of removal expenditures, a decrease of $19.0 million in income tax refunds received in 2025 compared to 2024, and the timing of other working capital items.
On May 1, 2025, our Board of Trustees approved a common share dividend payment of $0.7525 per share, payable on June 30, 2025 to shareholders of record as of May 15, 2025. In the first half of 2025, we paid cash dividends of $540.9 million and issued non-cash dividends of $11.8 million in the form of treasury shares, totaling dividends of $552.7 million. In the first half of 2024, we paid cash dividends of $490.9 million and issued non-cash dividends of $12.0 million in the form of treasury shares, totaling dividends of $502.9 million.
Eversource issues treasury shares to satisfy awards under the Company's incentive plans, shares issued under the dividend reinvestment and share purchase plan, and matching contributions under the Eversource 401k Plan.
In the first half of 2025, CL&P, NSTAR Electric and PSNH paid $330.0 million, $436.0 million and $175.0 million, respectively, in common stock dividends to Eversource parent.
44

Investments in Property, Plant and Equipment on the statements of cash flows do not include amounts incurred on capital projects but not yet paid, cost of removal, AFUDC related to equity funds, and the capitalized and deferred portions of pension and PBOP income/expense. In the first half of 2025, investments for Eversource, CL&P, NSTAR Electric, and PSNH were $2.05 billion, $438.2 million, $775.2 million, and $275.5 million, respectively. Capital expenditures were primarily for continuing projects to maintain and improve infrastructure and operations, including enhancing reliability to the transmission and distribution systems.
In June 2025, Eversource made a construction cost post-close purchase price adjustment payment related to the South Fork Wind project of $69 million, which is reflected in investing activities on the statement of cash flows.
Contractual Obligations: Our cash requirements from contractual obligations were reported in Item 7, "Management’s Discussion and Analysis of Financial Condition and Results of Operations," of the Eversource 2024 Form 10-K. There have been no material changes to our cash requirements from contractual obligations and payment schedules previously disclosed in our 2024 Form 10-K.
Credit Ratings: On June 24, 2025, Moody’s revised CL&P’s corporate credit rating from A3 to Baa1, its senior secured debt credit rating from A1 to A2 and outlook from negative to stable, citing the Connecticut regulatory environment as the reason for the downgrade.
Business Development and Capital Expenditures
Our consolidated capital expenditures, including amounts incurred but not paid, cost of removal, AFUDC, and the capitalized and deferred portions of pension and PBOP income/expense (all of which are non-cash factors), totaled $2.15 billion in the first half of 2025, compared to $2.26 billion in the first half of 2024. These amounts included $104.4 million and $152.7 million in the first half of 2025 and 2024, respectively, related to information technology and facilities upgrades and enhancements, primarily at Eversource Service and The Rocky River Realty Company.
Electric Transmission Business: Our consolidated electric transmission business capital expenditures decreased by $195.3 million in the first half of 2025, as compared to the first half of 2024. A summary of electric transmission capital expenditures by company is as follows:

| For the Six Months Ended June 30,
(Millions of Dollars) | 2025 |  | 2024
CL&P | $ | 159.3 |  |  | $ | 259.2 |
NSTAR Electric | 200.1 |  |  | 235.1 |
PSNH | 139.3 |  |  | 199.7 |
Total Electric Transmission | $ | 498.7 |  |  | $ | 694.0 |

Our transmission projects are designed to improve the reliability of the electric grid, meet customer demand for power, and strengthen the electric grid's resilience against extreme weather and other safety and security threats. In Connecticut, Massachusetts and New Hampshire, our transmission projects include transmission line upgrades, the installation of new transmission interconnection facilities, substations and lines, and transmission substation enhancements.
Greater Cambridge Energy Program: The Greater Cambridge Energy Program will construct Eversource’s first underground transmission substation in Cambridge, Massachusetts, along with associated transmission and distribution lines. The project will address the increased electric demand in the region, enhance the resiliency of the transmission system, and ensure a flexible grid to reliably serve customers. The flexibility to transmit and distribute mixed energy sources will support the decarbonization and electrification goals of both the City of Cambridge and the state of Massachusetts. The new 115/13.8-kV, 35,000 square foot substation will be located in an underground vault and includes three distribution power transformers supplying thirty-six distribution circuits. The project also includes five underground duct banks housing eight new 115-kV transmission lines. The Massachusetts Energy Facilities Siting Board approved the project on June 28, 2024. Additional required environmental permits are expected to be approved by the end of 2025, as well as a license from the MA DEP expected to be approved by the end of the second quarter of 2026. The initial in-service date for the project is June 2029, which includes two 115-kV transmission lines and the transmission portion of the substation. The first distribution circuits and substation distribution will be placed in-service by the end of 2029. The remaining transmission and distribution circuits will be placed in-service throughout 2030 and into 2031. The total project cost is approximately $1.84 billion, with $1.38 billion allocated for transmission and $460 million for distribution. As of June 30, 2025, $137.4 million has been spent on the project, with $104.5 million for transmission and $32.9 million for distribution.

Aging infrastructure relates to reliability and the replacement of water mains, regulators, storage tanks, pumping stations, wellfields, reservoirs, and treatment facilities. Load growth and other reflects growth in our service territory, including improvements of acquisitions, installation of new services, and interconnections of systems.
Pending Sale of Aquarion: On January 27, 2025, Eversource entered into a definitive agreement to sell the Aquarion water distribution business. Subject to certain closing adjustments, the aggregate enterprise value of the sale is approximately $2.4 billion in cash, which includes approximately $1.6 billion for the equity and $800 million of net debt that will be extinguished at closing. The sale is subject to approval by PURA, DPU and the NHPUC, as well as other approvals pursuant to the Hart-Scott-Rodino Antitrust Improvements Act, for which the relevant waiting period has expired, as well as other customary closing conditions. The sale is expected to close in late 2025. Eversource plans to use the net proceeds from the pending sale to pay down Eversource parent debt.
The assets and liabilities of the Aquarion water distribution business met the criteria to be classified as held for sale and have been classified separately as current or long-term assets and liabilities held for sale on the Eversource balance sheets as of June 30, 2025 and December 31, 2024. For further information, see Note 17, “Assets Held for Sale.”
FERC Regulatory Matters
FERC ROE Complaints: Four separate complaints were filed at the FERC by combinations of New England state attorneys general, state regulatory commissions, consumer advocates, consumer groups, municipal parties and other parties (collectively, the Complainants). In each of the first three complaints, filed on October 1, 2011, December 27, 2012, and July 31, 2014, respectively, the Complainants challenged the NETOs' base ROE of 11.14 percent that had been utilized since 2005 and sought an order to reduce it prospectively from the date of the final FERC order and for the separate 15-month complaint periods. In the fourth complaint, filed April 29, 2016, the Complainants challenged the NETOs' base ROE billed of 10.57 percent and the maximum ROE for transmission incentive (incentive cap) of 11.74 percent, asserting that these ROEs were unjust and unreasonable.
The ROE originally billed during the period October 1, 2011 (beginning of the first complaint period) through October 15, 2014 consisted of a base ROE of 11.14 percent and incentives up to 13.1 percent. On October 16, 2014, FERC issued Opinion No. 531-A and set the base ROE at 10.57 percent and the incentive cap at 11.74 percent for the first complaint period. This was also effective for all prospective billings to customers beginning October 16, 2014. This FERC order was vacated on April 14, 2017 by the U.S. Court of Appeals for the D.C. Circuit (the Court).
All amounts associated with the first complaint period have been refunded. Eversource has recorded a reserve of $39.1 million (pre-tax and excluding interest) for the second complaint period as of both June 30, 2025 and December 31, 2024. This reserve represents the difference between the billed rates during the second complaint period and a 10.57 percent base ROE and 11.74 percent incentive cap. The reserve consisted of $21.4 million for CL&P, $14.6 million for NSTAR Electric and $3.1 million for PSNH as of both June 30, 2025 and December 31, 2024.
46

On October 16, 2018, FERC issued an order on all four complaints describing how it intends to address the issues that were remanded by the Court. FERC proposed a new framework to determine (1) whether an existing ROE is unjust and unreasonable and, if so, (2) how to calculate a replacement ROE. Initial briefs were filed by the NETOs, Complainants and FERC Trial Staff on January 11, 2019 and reply briefs were filed on March 8, 2019. The NETOs' brief was supportive of the overall ROE methodology determined in the October 16, 2018 order provided the FERC does not change the proposed methodology or alter its implementation in a manner that has a material impact on the results.
The FERC order included illustrative calculations for the first complaint using FERC's proposed frameworks with financial data from that complaint. Those illustrative calculations indicated that for the first complaint period, for the NETOs, which FERC concludes are of average financial risk, the preliminary just and reasonable base ROE is 10.41 percent and the preliminary incentive cap on total ROE is 13.08 percent.
If the results of the illustrative calculations were included in a final FERC order for each of the complaint periods, then a 10.41 percent base ROE and a 13.08 percent incentive cap would not have a significant impact on our financial statements for all of the complaint periods. These preliminary calculations are not binding and do not represent what we believe to be the most likely outcome of a final FERC order.
On November 21, 2019, FERC issued Opinion No. 569 affecting the two pending transmission ROE complaints against the Midcontinent ISO (MISO) transmission owners, in which FERC adopted a new methodology for determining base ROEs. Various parties sought rehearing. On December 23, 2019, the NETOs filed supplementary materials in the NETOs' four pending cases to respond to this new methodology because of the uncertainty of the applicability to the NETOs' cases. On May 21, 2020, the FERC issued its order in Opinion No. 569-A on the rehearing of the MISO transmission owners' cases, in which FERC again changed its methodology for determining the MISO transmission owners' base ROEs. On November 19, 2020, the FERC issued Opinion No. 569-B denying rehearing of Opinion No. 569-A and reaffirmed the methodology previously adopted in Opinion No. 569-A. The new methodology differs significantly from the methodology proposed by FERC in its October 16, 2018 order to determine the NETOs' base ROEs in their four pending cases. FERC Opinion Nos. 569-A and 569-B were appealed to the Court. On August 9, 2022, the Court issued its decision vacating MISO ROE FERC Opinion Nos. 569, 569-A and 569-B and remanded to FERC to reopen the proceedings. The Court found that FERC’s development of the new return methodology was arbitrary and capricious due to FERC’s failure to offer a reasonable explanation for its decision to reintroduce the risk-premium financial model in its new methodology for calculating a just and reasonable return.
On October 17, 2024, FERC issued an order on the remand of the MISO ROE proceedings. The order addressed the Court’s decision that the reintroduction of the risk-premium financial model in the ROE methodology was arbitrary and capricious by removing the risk-premium financial model from the ROE methodology. The removal of the risk-premium financial model was the only revision to FERC’s ROE methodology and resulted in a two-model approach utilizing the two-step discounted cash flow model and the capital asset pricing model. MISO transmission owners were directed to provide refunds for the period November 12, 2013 to February 11, 2015 (the first MISO ROE complaint refund period) and for the period from September 28, 2016 (the date of FERC’s order on the first MISO ROE complaint) to October 17, 2024 by December 1, 2025. The order also stated that FERC does not preclude the use of the risk-premium financial model in future proceedings if the parties can demonstrate that FERC’s stated concerns around the inclusion of the model have been addressed. On March 25, 2025, FERC issued an order addressing arguments raised on rehearing, sustaining the result, and denying rehearing.
On November 13, 2024, the NETOs filed a supplemental brief in their four pending ROE proceedings to explain to FERC that it cannot apply the reasoning and methodologies of the MISO ROE case to the NETOs’ cases due to the entirely different set of facts in the MISO and NETOs ROE proceedings. Doing so would violate the substance of the Court’s April 14, 2017 order and would violate the legal standard required by the Federal Power Act.
On February 4, 2025, the MISO transmission owners submitted a petition for review with the Court requesting review of the October 17, 2024 MISO ROE order on remand and a December 19, 2024 notice of denial of rehearing. The petition requests review of FERC’s decision to retroactively backdate the MISO transmission owners’ base ROE to the date of an earlier order that FERC abandoned when it issued Order No. 569, treat an underlying unlawful complaint as if it were legitimate, and order eight years of interest as part of the directed refunds. On July 11, 2025, the Court issued an order on the briefing schedule with initial briefs due August 14, 2025 and final briefs due January 26, 2026.
Given the significant uncertainty regarding the applicability of the FERC order in the MISO transmission owners’ two complaint cases to the NETOs’ pending four complaint cases due to the complex differences between the cases, Eversource concluded that there is no reasonable basis for a change to the reserve or recognized ROEs for any of the complaints or subsequent periods at this time and Eversource cannot reasonably estimate any potential range of loss for any of the four complaint proceedings at this time. The resolution of these proceedings could have a material impact on the financial condition, results of operations and cash flows.
Eversource, CL&P, NSTAR Electric and PSNH currently record revenues at the 10.57 percent base ROE and incentive cap at 11.74 percent established in the October 16, 2014 FERC order.
A change of 10 basis points to the base ROE used to establish the reserves would impact Eversource’s after-tax earnings by an average of approximately $3 million for each of the four 15-month complaint periods. Prospectively from the date of a final FERC order implementing a new base ROE, based off of actual 2024 rate base, a change of 10 basis points to the base ROE would impact Eversource’s future annual after-tax earnings by approximately $6 million per year, and will increase slightly over time as we continue to invest in our transmission infrastructure.

Transmission Rates and Other Transmission Rates-Related Proceedings: CL&P, NSTAR Electric and PSNH transmission rates are calculated in accordance with a FERC-approved formula ratemaking framework, and each utility is required to file an annual update on or before July 31st with resulting rates effective January 1st the following year. The formula rate framework provides for an annual reconciliation of the prior calendar year actual costs incurred related to our transmission facilities, including an allowed ROE, plus forecasted information through the next rate period. The annual update process includes formula rate protocols that provide disclosure of cost inputs, an opportunity for informal discovery procedures and a challenge process, which provides transparency to stakeholders.
From time to time, various matters are pending before FERC relating to transmission rates, incentives, interconnections and transmission planning. Depending on the outcome, any of these matters could materially impact our results of operations and financial condition. At this time, Eversource cannot predict the ultimate outcome of the matters currently pending before FERC, and the resulting impact on its transmission incentives or planning.
Regulatory Developments and Rate Matters
Electric, Natural Gas and Water Utility Base Distribution Rates: The regulated companies’ distribution rates are set by their respective state regulatory commissions, and their tariffs include mechanisms for periodically adjusting their rates for the recovery of specific incurred costs. Other than as described below, for the first half of 2025, changes made to the regulated companies’ rates did not have a material impact on their earnings. For further information, see "Financial Condition and Business Analysis – Regulatory Developments and Rate Matters" included in Item 7, "Management’s Discussion and Analysis of Financial Condition and Results of Operations," of the Eversource 2024 Form 10-K.
Connecticut:
CL&P Performance Based Rate Making: On May 26, 2021, in accordance with an October 2020 Connecticut law, PURA opened a proceeding to begin to evaluate and eventually implement performance-based regulation (PBR) for electric distribution companies. PURA is conducting the proceeding in two phases. On January 25, 2023, PURA staff issued a proposal that outlined a suggested portfolio of PBR elements for further exploration and potential implementation in the second phase of the proceeding. On April 26, 2023, PURA issued a final decision on the first phase and identified various objectives to guide PBR development and evaluate adoption of a PBR framework. The decision commenced Phase 2 by initiating three reopener dockets focused on revenue adjustment mechanisms, performance metrics and integrated distribution system planning.
On November 16, 2023, PURA issued a straw proposal in the first reopener that focused on revenue adjustment mechanisms. The proposal outlined potential additions and reforms to the current revenue adjustment mechanisms, such as multi-year rate plans, earnings sharing mechanisms and the revenue decoupling mechanism. On March 14, 2024, PURA issued a straw proposal in the second reopener docket that concentrated on performance mechanisms in a PBR framework. The proposal suggested the development of performance incentive mechanisms, reported metrics and scorecards. On February 27, 2025, PURA issued revised straw proposals for both the first and second reopener dockets, resulting in some edits to the previous proposals based on participant feedback. On April 4, 2025, PURA issued a straw proposal in the third reopener docket that focused on the establishment of integrated distribution system planning under a PBR framework.
On July 14, 2025, PURA issued proposed final decisions in the first two reopener dockets. The proposed final decision in the first reopener docket adopted a PBR framework inclusive of a multi-year rate plan with an attrition relief mechanism that uses a revenue-cap formula approach to adjust revenues based on a variety of factors including inflation, a productivity factor, a customer dividend percentage, an exogenous cost factor and a capital funding mechanism, as well as an earnings sharing mechanism and a revenue decoupling mechanism for implementation in CL&P’s next distribution rate case. The multi-year rate plan has a stay out period of four years, but certain situations, such as deteriorating financial condition, exceeding authorized return, falling interest rates, or excess storm costs, could trigger the initiation of a new rate amendment proceeding during the multi-year rate plan. The proposed final decision in the second reopener docket established reporting parameters, including the commencement of scorecards and reported metrics and the development of company specific performance incentive mechanisms. By November 1, 2025, CL&P will submit an Interim Performance Mechanism Filing with PURA detailing the results of the reported metrics and scorecards in the PBR Performance Metrics Portfolio for calendar years 2020 through 2024. Results of scorecards and reported metrics are proposed to be reported annually thereafter to PURA, beginning March 1, 2026. Company specific performance incentive mechanisms will be implemented in CL&P’s next rate case proceeding.
Final decisions on the three reopener dockets are expected in 2025. We continue to monitor developments in this proceeding, and at this time, we cannot predict the ultimate outcome of this proceeding and the resulting impact to CL&P.
CL&P Storm Filings: On March 28, 2024, PURA established a prudency review proceeding for the purpose of receiving and reviewing evidence of the costs reported by CL&P in response to catastrophic storms and pre-staging events totaling approximately $634 million that occurred between January 1, 2018 and December 31, 2021. On December 31, 2024, CL&P filed a supplement to its March 2024 prudency review application to request that PURA evaluate the prudence of its costs for nine additional catastrophic storms and two additional pre-staging events for the period January 1, 2022 through January 31, 2023 totaling approximately $173 million. On July 10, 2025, CL&P filed a second supplement to its March 2024 prudency review application to request that PURA evaluate the prudence of its costs for ten additional catastrophic storms for the period February 1, 2023 through December 31, 2023 totaling approximately $171 million. Although we cannot predict the ultimate outcome of this matter, we continue to believe these deferred storm restoration costs were prudently incurred and are probable of recovery. On July 25, 2025, CL&P filed a third supplement in this application to include carrying charges calculated at the weighted average cost of capital on the deferred storm costs totaling $246 million, which reflects CL&P’s actual financing costs on the unpaid storm costs from the date the deferred storm costs first began to accrue through May 2025. These carrying charges have not been deferred on the balance sheet. PURA’s procedural schedule includes briefs due in the first quarter of 2026.

Yankee Gas Distribution Rate Case: On November 12, 2024, Yankee Gas filed an application with PURA to amend its existing distribution rates for effect on November 1, 2025. Yankee Gas’s rate application requested approval of a distribution rate increase of $209 million, which included a base distribution rate increase of $274 million, partially offset by a reduction of $65 million in the combined Gas System Improvements and System Expansion Reconciliation rates. Yankee Gas subsequently updated its proposed cost of service through a series of supplemental filings to incorporate updates resulting in an amended requested distribution rate increase of $193 million. In addition, Yankee Gas requested approval to implement a rate credit of $37.4 million to offset the PGA rate for non-firm margin credits over one year beginning November 1, 2025. As part of the rate case, Yankee Gas proposed to implement a multi-year performance-based rate making plan with a four-year initial term from November 1, 2025 to October 31, 2029 that would adjust rates annually and includes performance metrics. A final decision by PURA is expected in October 2025.
Aquarion Water Company of Connecticut Distribution Rate Case: On August 29, 2022, Aquarion Water Company of Connecticut (AWC-CT) filed an application with PURA to amend its existing rate schedules to address an operating revenue deficiency. AWC-CT’s rate application requested approval of rate increases of $27.5 million, an additional $13.6 million, and an additional $8.8 million, effective March 15, 2023, 2024, and 2025, respectively. On March 15, 2023, PURA issued a final decision that rejected this request. In this decision, PURA ordered a decrease to total authorized revenues of $4.0 million effective March 15, 2023. The decision allows an authorized regulatory ROE of 8.70 percent. On March 30, 2023, AWC-CT filed an appeal on the decision. On March 25, 2024, the State of Connecticut Superior Court issued a decision on the appeal which dismissed nine, remanded back to PURA two, and partially remanded one of AWC-CT’s twelve claims of error in its appeal. On March 28, 2024, AWC-CT filed an appeal of the Connecticut Superior Court decision to the Connecticut Appellate Court, and that appeal was subsequently transferred to the Connecticut Supreme Court. On July 9, 2025, the Connecticut Supreme Court issued a decision that overturned PURA’s disallowance of $1.5 million in water conservation program expenses, but affirmed the remaining portions of PURA’s decision that were challenged on appeal. There is no statutory timeline for PURA to address this decision. The decision did not have a financial impact on Eversource’s financial statements. The Connecticut Supreme Court decision also validated AWC-CT’s argument that the correct legal standard PURA must use in determining whether costs can be recovered through customer rates is the longstanding prudence standard, which evaluates the prudence of management decision-making as of the time the utility made the decision to incur costs; PURA cannot use improper hindsight analysis to evaluate prudence.
Massachusetts:
NSTAR Gas Distribution Rates: NSTAR Gas’ PBR mechanism allows for an annual adjustment to base distribution rates for inflation and exogenous events. On June 16, 2025, NSTAR Gas submitted its annual PBR Adjustment filing reflecting a $163.1 million increase to base distribution rates for effect on November 1, 2025. The base distribution rate increase is comprised of a $10.8 million inflation-based adjustment and, in accordance with the DPU’s final decision in the 2020 NSTAR Gas rate case, a $152.3 million rate-base reset to incorporate capital additions for the period 2021 through 2024, which includes the transfer of GSEP investments totaling $107.3 million into base rates, as well as other non-GSEP plant additions totaling $45.0 million. As part of this filing, NSTAR Gas proposed to pause recovery of the Gas System Enhancement Adjustment Factor (GSEAF) and reduce the current GSEAF to zero on November 1, 2025 in order to align this decrease with the base rate increase, and to mitigate November 1, 2025 bill impacts to customers. NSTAR Gas would begin to recover the remaining 2025 GSEP revenue requirement, estimated at $72 million, on May 1, 2026 over 18 months with applicable carrying charges estimated at $2.5 million. DPU approval is expected by October 31, 2025.
NSTAR Electric’s Electric Sector Modernization Plan (ESMP) Filing: On August 29, 2024, the DPU approved the overall ESMP as a strategic plan for a five-year period commencing July 1, 2025 through June 30, 2030. The initial five-year plan proposed incremental distribution capital investments of $608 million and incremental distribution expense of $211 million. On November 21, 2024, the DPU opened a second phase of the proceeding (Phase II) to consider a short-term ESMP-focused cost recovery mechanism and metrics. The DPU limited the review of investment in this docket and excluded NSTAR Electric’s ESMP capital proposals regarding the EV Phase II extension and the new capital investment projects, and expense for the funding of low and moderate income solar. These investments will be reviewed in separate proceedings. This reduced the amount of company-proposed incremental capital investment to $295 million and the incremental expense to $44 million related to resiliency and grid modernization for a total spending cap of $339 million. NSTAR Electric filed its proposed tariff and testimony on December 18, 2024.
On June 13, 2025, the DPU issued an order in the Phase II proceeding on the interim cost recovery mechanism for the ESMP, which approved the interim cost recovery mechanism with certain modifications. In the order, the DPU emphasized its attempt to balance affordability and the goals of advancing Massachusetts’ clean energy goals through proactive investments to support electrification and distributed generation. NSTAR Electric received approval for its proposed grid modernization and resiliency investments and incremental expense for a total spending cap of $139 million, reflecting an ordered reduction in capital spending on undergrounding for resiliency. In compliance with the Phase II order, a revised tariff was filed June 23, 2025, and the revised ESMP spending cap for the first term of July 1, 2025 through June 30, 2030, which included company-proposed incremental capital investment of $95 million and incremental expense of $44 million, was filed June 30, 2025. The DPU intends to conduct another phase of this proceeding to establish a long-term cost recovery mechanism, which is expected to be through base distribution rates.
New Hampshire:
PSNH Distribution Rate Case: On June 11, 2024, PSNH filed an application with the NHPUC for approval of a temporary annual base distribution rate increase. On July 31, 2024, the NHPUC approved a settlement agreement that was reached by PSNH, New Hampshire Department of Energy, and the Office of the Consumer Advocate to implement a temporary annual base distribution rate increase of $61.2 million effective August 1, 2024.
49

Also on June 11, 2024, PSNH filed an application with the NHPUC to request an increase in permanent base distribution rates of $181.9 million, which is inclusive of the temporary rate increase. Throughout the course of the proceeding, PSNH amended its requested rate increase to $103 million, primarily reflecting the removal of deferred storm costs which will be addressed in a separate proceeding. On July 25, 2025, the NHPUC issued its decision in the PSNH distribution rate case and approved a permanent rate increase of $100.7 million, effective August 1, 2025, inclusive of the temporary rate increase referenced above. The total distribution revenue requirement effective August 1, 2025 is $519 million. The order also established an authorized regulatory ROE of 9.5 percent with a 50 percent common equity ratio in PSNH’s capital structure. The order allowed for the effect of the permanent rate increase to be extended back to the temporary rate period, subject to conditions and limitations included in the decision. This recoupment will be collected through the Regulatory Reconciliation Adjustment (RRA) regulatory tracking mechanism over a one-year period. PSNH is currently working through the recoupment calculation, which will be filed by August 11, 2025 with the NHPUC.
This revenue requirement also contains an alternative regulation distribution revenue requirement adjustment. The NHPUC approved a first-of-its-kind in New Hampshire, alternative regulatory framework that authorizes annual revenue adjustments on August 1st of 2026, 2027 and 2028, with a requirement for PSNH to file for its next base distribution rate increase for effect in June 2029. The alternative regulatory framework includes a revenue-cap formula adjusted for annual inflation and a productivity factor adjustment to provide PSNH with increased revenue for capital and overhead necessary to run its business, an exogenous events recovery mechanism, performance metrics and an earnings sharing mechanism. Consistent with PSNH’s proposal, lost base revenues for both net metering and energy efficiency are eliminated effective August 1, 2025.
As part of the decision, unrecovered storm costs of $247 million were removed from the rate proceeding for consideration in a separate proceeding. Approval of the ultimate amount of storm costs to be recovered is subject to a separate prudency review that was filed in March of 2024 and is being considered by the NHPUC in a separate dedicated docket, which is at this time complete and awaiting the issuance of an order. Approved storm costs in excess of the amount approved in base rates will be recovered through the RRA regulatory tracking mechanism. The NHPUC increased the level of storm costs recovered in base rates from $12 million to $19 million.
Legislative, Policy and Legal Matters
Federal: On July 4, 2025, An Act to Provide for Reconciliation Pursuant to Title II of H. Con. Res. 14 (known as the One Big Beautiful Bill Act or OBBBA), a budget and reconciliation package, was signed into law. Among various items, the law includes changes to federal tax policy and modifications to clean energy tax incentives originally enacted under the Inflation Reduction Act of 2022. One of the key provisions notable for Eversource is the restoration of bonus depreciation for its affiliates other than rate-regulated utility companies. The deduction is for qualifying depreciable tangible property acquired and placed in service after January 19, 2025. The phase out of bonus depreciation under the Tax Cuts and Jobs Act of 2017 has been eliminated. The OBBBA maintains a federal corporate income tax rate of 21 percent.
The OBBBA also includes provisions that remove federal tax credits for renewable energy. The OBBBA phases out the clean electricity production credit and the clean electricity investment tax credit for wind and solar projects that begin construction after July 4, 2026 and are not placed in service before December 31, 2027. Projects that begin construction prior to July 4, 2026 will remain eligible for investment tax credit benefits under the Inflation Reduction Act of 2022.
The Company is currently evaluating the impacts of the OBBBA on our consolidated financial statements. The law will not have an impact on Eversource’s tax equity investment in the South Fork Wind project or the Revolution Wind project for which Eversource has remaining financial obligations. The ultimate impact of the law will depend on future guidance from the U.S. Department of the Treasury, the Internal Revenue Service, and state regulatory bodies.
Connecticut: On July 1, 2025, Connecticut enacted Public Act No. 25-173 (Senate Bill No. 4) (the Act), which aims to reduce electric rates for retail customers by up to $300 million over the next two years in the public benefits charges on electric bills for hardship protection measures and electric vehicle program costs through the issuance of state bonds that would fully fund these state-mandated program costs in lieu of collecting these amounts in electric rates. These changes are expected to be implemented prospectively, and rate changes could be implemented as early as September 1, 2025 in CL&P’s revenue adjustment mechanism.
The Act authorizes the securitization of storm-related expenses for the period January 1, 2018 through January 1, 2025, which covers the majority of deferred storm costs on the CL&P balance sheet, as well as advanced metering infrastructure (AMI) and legacy meter investments, allowing for the recovery of these costs from customers over a longer term to mitigate short-term rate impacts. The Act also seeks to reduce electric rates for retail customers by revising the statutory framework for renewable portfolio standards.
The Act also directs PURA’s procurement manager, after consultation with the electric distribution companies, the Consumer Counsel and the Commissioner of DEEP, to file with PURA by February 15, 2026 a proposed amendment to the plan to procure standard electric service that would authorize electric distribution companies to, among other things, make dynamic market purchases to attempt to reduce the average cost and minimize the price volatility of standard electric service.
Implementation of the Act’s provisions will require further regulatory proceedings and administrative action. We do not anticipate any significant impact to our operating revenues or earnings as a result of the Act’s enactment. However, we expect PURA to initiate proceedings related to securitization, renewable portfolio standard obligations, and other provisions in the Act, which may impact future rate design and recovery mechanisms.

PFAS Settlements: Aquarion opted into class-action settlements with the defendants 3M Company, E.I. DuPont de Nemours and Company, Tyco Fire Products LP, and BASF Corporation. These settlement agreements were entered to resolve claims of per- and polyfluoroalkyl substances (PFAS) contamination in the drinking water provided by public water systems. In July 2024 and April 2025, Aquarion and other qualifying class members submitted claims to receive settlement awards; these awards were allocated based on the overall number of claimants, PFAS concentrations and flow rates of water sources, and a variety of other factors. The final, total recovery from these settlements is unknown and will be based on the Claims Administrator’s review of the submitted claims and the subsequent allocation procedures. Aquarion anticipates receiving recovery from 3M Company over the next nine years and from E.I. DuPont de Nemours and Company over the next two years. The schedule for BASF Corporation and Tyco Fire Products LP are unknown at this time. In the second quarter of 2025, Aquarion received $3.2 million of proceeds. Proceeds from the settlements will be used to fund capital expenditures.
Critical Accounting Policies
The preparation of financial statements in conformity with GAAP requires management to make estimates, assumptions and, at times, difficult, subjective or complex judgments. Changes in these estimates, assumptions and judgments, in and of themselves, could materially impact our financial position, results of operations or cash flows. Our management discusses with the Audit Committee of our Board of Trustees significant matters relating to critical accounting policies. Our critical accounting policies that we believed were the most critical in nature were reported in the Eversource 2024 Form 10-K. There have been no material changes with regard to these critical accounting policies.

Weather, fluctuations in energy supply rates, conservation measures (including utility-sponsored energy efficiency programs), and economic conditions affect customer energy usage and water consumption. Industrial sales volumes are less sensitive to temperature variations than residential and commercial sales volumes. In our service territories, weather impacts both electric and water sales volumes during the summer and both electric and natural gas sales volumes during the winter; however, natural gas sales volumes are more sensitive to temperature variations than electric sales volumes. Customer heating or cooling usage may not directly correlate with historical levels or with the level of degree-days that occur.
Fluctuations in retail electric sales volumes at PSNH impact earnings ("Traditional" in the table above). For CL&P, NSTAR Electric, NSTAR Gas, EGMA, Yankee Gas, and our Connecticut water distribution business, fluctuations in retail sales volumes do not materially impact earnings due to their respective regulatory commission-approved distribution revenue decoupling mechanisms ("Decoupled" in the table above). These distribution revenues are decoupled from their customer sales volumes, which breaks the relationship between sales volumes and revenues recognized.
Operating Revenues: The variance in Operating Revenues by segment is as follows:

(Millions of Dollars) | Three Months Ended |  | Six Months Ended
Electric Distribution | $ | 200.1 |  |  | $ | 716.1 |
Natural Gas Distribution | 67.3 |  |  | 302.6 |
Electric Transmission | 34.6 |  |  | 74.6 |
Water Distribution | 3.6 |  |  | 3.6 |
Other | 10.6 |  |  | 6.1 |
Eliminations | (11.6) |  |  | (12.7) |
Total Operating Revenues | $ | 304.6 |  |  | $ | 1,090.3 |

Electric and Natural Gas Distribution Revenues:
Base Distribution Revenues:
•Base electric distribution revenues increased $26.8 million and $62.2 million for the three and six month periods, due primarily to a temporary base distribution rate increase at PSNH effective August 1, 2024 and a base distribution rate increase at NSTAR Electric effective January 1, 2025.
•Base natural gas distribution revenues increased $24.0 million and $79.7 million for the three and six month periods, due primarily to base distribution rate increases effective November 1, 2024 at EGMA and NSTAR Gas.
NSTAR Electric’s PBR mechanism allows for an annual adjustment to base distribution rates for inflation, exogenous events and future capital additions based on a historical five-year average of total capital additions. On December 23, 2024, the DPU approved a $55.8 million increase to base distribution rates for effect on January 1, 2025.
On July 31, 2024, the NHPUC approved a settlement agreement to implement a temporary annual base distribution rate increase of $61.2 million effective August 1, 2024 at PSNH.
NSTAR Gas’ PBR mechanism allows for an annual adjustment to base distribution rates for inflation and exogenous events. On October 30, 2024, the DPU approved the annual PBR Adjustment filing for a $12.7 million increase to base distribution rates for effect on November 1, 2024.
EGMA was allowed two rate base resets in a DPU-approved October 7, 2020 rate settlement agreement, with the first rate base reset on November 1, 2024. After adjusting for a cap required under the terms of the rate settlement agreement, the increase to base distribution rates was $85.6 million effective November 1, 2024 (of which $8.8 million is offset by a reduction in the GSEP revenue requirement and GSEP rate also taking effect on November 1, 2024 for a net distribution rate change on November 1, 2024 of $76.8 million). On November 7, 2024, the DPU approved this filing.

Tracked Distribution Revenues: Tracked distribution revenues consist of certain costs that are recovered from customers in retail rates on a fully reconciling basis through regulatory commission-approved cost tracking mechanisms and therefore, recovery of these costs has no impact on earnings. Costs recovered through cost tracking mechanisms include, among others, energy supply and natural gas supply procurement, state mandated energy purchase agreements and other energy-related costs, electric retail transmission charges, energy efficiency program costs, electric restructuring and stranded cost recovery revenues (including securitized RRB charges), certain capital tracking mechanisms for infrastructure improvements, and additionally for the Massachusetts utilities, pension and PBOP benefits, net metering for distributed generation, and solar-related programs. Revenues from certain of these cost tracking mechanisms also include certain incentives earned, return on capital tracking mechanisms, and carrying charges that are billed in rates to customers, which do impact earnings. Tracked revenues also include wholesale market sales transactions, such as sales of energy and energy-related products into the ISO-NE wholesale electricity market, sales of natural gas to third party marketers, and the sale of RECs to various counterparties.
Customers have the choice to purchase electricity from their Eversource electric utility or from a competitive third party supplier. For customers who have contracted separately with these competitive suppliers, revenue is not recorded for the sale of the electricity commodity, as the utility is acting as an agent on behalf of the third party supplier. For customers that choose to purchase electric generation from CL&P, NSTAR Electric or PSNH, each utility purchases power on behalf of, and is permitted to recover the related energy supply cost without mark-up from, its customers, and records offsetting amounts in revenues and purchased power related to this energy supply procurement. CL&P, NSTAR Electric and PSNH each remain as the distribution service provider for all customers and charge a regulated rate for distribution delivery service recorded in revenues. Certain eligible natural gas customers may elect to purchase natural gas from their Eversource natural gas utility or may contract separately with a gas supply operator. Revenue is not recorded for the sale of the natural gas commodity to customers who have contracted separately with these operators, only the delivery to a customer, as the utility is acting as an agent on behalf of the gas supply operator.
The variance in tracked distribution revenues for the three and six month periods is due primarily to the following:

| Electric Distribution |  | Natural Gas Distribution
(Millions of Dollars) | Three Months Ended |  | Six Months Ended |  | Three Months Ended |  | Six Months Ended
Retail Tariff Tracked Revenues: |  |  |  |  |  |  |
Energy supply procurement | $ | (85.6) |  |  | $ | (173.2) |  |  | $ | 28.7 |  |  | $ | 135.6 |
CL&P NBFMCC | 126.4 |  |  | 344.1 |  |  | — |  |  | — |
CL&P SBC | 64.3 |  |  | 153.6 |  |  | — |  |  | — |
Retail transmission | 39.5 |  |  | 66.9 |  |  | — |  |  | — |
Other distribution tracking mechanisms | 5.8 |  |  | 58.1 |  |  | 1.1 |  |  | 68.6 |
Wholesale Market Sales Revenue | 23.2 |  |  | 205.6 |  |  | 13.9 |  |  | 18.0 |

Fluctuations in retail tariff tracked revenues are driven by adjustments to retail rates to recover costs and changes in sales volumes.
The decrease in energy supply procurement within electric distribution for the three month period was driven by lower average prices and lower average supply-related sales volumes. The decrease in energy supply procurement within electric distribution for the six month period was driven by lower average prices, partially offset by higher average supply-related sales volumes. The increase in energy supply procurement within natural gas distribution for the three month period was driven by higher average prices, partially offset by lower average supply-related sales volumes. The increase in energy supply procurement within natural gas distribution for the six month period was driven by higher average prices and higher average supply-related sales volumes.
The increase in CL&P’s NBFMCC revenues was driven by an increase in the retail Non-Bypassable Federally Mandated Congestion Charge (NBFMCC) rate. The CL&P NBFMCC rate includes the recovery of costs incurred under long-term state mandated energy purchase contracts with the Millstone and Seabrook nuclear power plants, net of the benefits received from selling this energy into the ISO-NE wholesale market. Effective September 1, 2023, CL&P’s average NBFMCC rate changed to $0.00293 per kWh. As a result of the April 2024 interim decision in the 2024 CL&P RAM filing, the average NBFMCC rate increased to $0.03906 per kWh effective July 1, 2024. As a result of the August final decision in the 2024 CL&P RAM filing, the average NBFMCC rate increased to $0.04290 per kWh effective September 1, 2024. The rate increases primarily resulted from higher net costs associated with power purchase agreements with the Millstone and Seabrook nuclear power plants.
The increase in electric distribution wholesale market sales revenue for the three and six month periods was due primarily to higher average electricity market prices received for wholesale sales at CL&P. ISO-NE average market prices received for CL&P’s wholesale sales increased to an average price of $39.07 per MWh and $72.46 per MWh for the three and six months ended June 30, 2025, as compared to $28.30 per MWh and $32.90 per MWh for the same periods in 2024, driven primarily by higher natural gas prices in New England. Volumes sold into the market were primarily from the sale of output generated by the Millstone PPA and Seabrook PPA with CL&P.
CL&P is required by regulation to purchase electric generation from Millstone and Seabrook under PURA-approved PPAs entered into in 2019. CL&P does not have legislative authority to use this purchased output to serve its customer load and therefore sells the energy into the wholesale market and uses the proceeds from the energy sales to offset the contract costs. The net cost or net sales amount is recovered from, or refunded to, customers in the non-bypassable component of the CL&P FMCC rate. Changes in CL&P’s NBFMCC retail revenues and CL&P’s wholesale market sales, as compared to the actual costs incurred, are deferred on the income statement by an offset to amortization expense.
Electric Transmission Revenues: Electric transmission revenues increased $34.6 million and $74.6 million for the three and six month periods, due primarily to a higher transmission rate base as a result of our continued investment in our transmission infrastructure.
53

Other Revenues and Eliminations: Other revenues primarily include the revenues of Eversource's service company, most of which are eliminated in consolidation. Eliminations are also related to the Eversource electric transmission revenues that are derived from ISO-NE regional transmission charges to the distribution businesses of CL&P, NSTAR Electric and PSNH that recover the costs of the wholesale transmission business in rates charged to their customers.
Purchased Power, Purchased Natural Gas and Transmission expense includes costs associated with providing electric generation service supply and natural gas to all customers who have not migrated to third party suppliers, the cost of energy purchase contracts entered into as required by regulation, and transmission costs. These electric and natural gas supply procurement costs, other energy-related costs, and transmission costs are recovered from customers in rates through commission-approved cost tracking mechanisms, which have no impact on earnings (tracked costs). The variance in Purchased Power, Purchased Natural Gas and Transmission expense is due primarily to the following:

(Millions of Dollars) | Three Months Ended |  | Six Months Ended
Energy supply procurement costs | $ | (84.0) |  |  | $ | (171.9) |
Other electric distribution costs | (8.0) |  |  | 55.7 |
Natural gas supply costs | 30.4 |  |  | 136.8 |
Transmission costs | 38.2 |  |  | 66.3 |
Eliminations | 0.7 |  |  | (5.2) |
Total Purchased Power, Purchased Natural Gas and Transmission | $ | (22.7) |  |  | $ | 81.7 |

The variance in energy supply procurement costs is offset in Operating Revenues (tracked energy supply procurement revenues). The decrease in other electric distribution costs for the three month period is due primarily to lower long-term contractual energy-related costs that are recovered in the non-bypassable component of the FMCC mechanism at CL&P and lower stranded costs resulting from higher Regional Greenhouse Gas Initiative (RGGI) proceeds received at PSNH, which are credited back to customers, partially offset by an increase at NSTAR Electric in both the long-term renewable energy contract cost deferral and in net metering costs.
The increase in other electric distribution costs for the six month period is due primarily to increases at NSTAR Electric in the long-term renewable energy contract cost deferral and in net metering costs. These increases were partially offset by lower stranded costs resulting from higher RGGI proceeds received at PSNH, which are credited back to customers, and lower long-term contractual energy-related costs that are recovered in the non-bypassable component of the FMCC mechanism at CL&P.
Costs at the natural gas distribution segment relate to supply procurement costs for retail customers. Total natural gas costs increased for the three month period due primarily to higher average prices and an increase in the retail cost deferral, partially offset by lower average purchased volumes. Total natural gas costs increased for the six month period due primarily to higher average prices and higher average purchased volumes, partially offset by a decrease in the retail cost deferral.
Included in transmission costs are charges that recover the cost of transporting electricity over high-voltage lines from generation facilities to substations, including costs allocated by ISO-NE to maintain the wholesale electric market. The increase in transmission costs for the three and six month periods was primarily the result of an increase in costs billed by ISO-NE that support regional grid investments and an increase in Local Network Service charges, which reflect the cost of transmission service provided by Eversource over our local transmission network. These increases were partially offset by a decrease in the retail transmission cost deferral, which reflects the actual cost of transmission service compared to estimated amounts billed to customers.
54

Operations and Maintenance expense includes tracked costs and costs that are part of base electric, natural gas and water distribution rates with changes impacting earnings (non-tracked costs). The variance in Operations and Maintenance expense is due primarily to the following:

(Millions of Dollars) | Three Months Ended |  | Six Months Ended
Base Electric Distribution (Non-Tracked Costs): |  |  |
Uncollectible Expense | $ | 3.8 |  |  | $ | 6.1 |
Storm costs | 4.6 |  |  | (1.9) |
Shared corporate costs (including IT system depreciation at Eversource Service) | 1.6 |  |  | 4.9 |
General corporate costs (including vendor services in corporate areas, insurance, fees and assessments) | (3.7) |  |  | 3.2 |
Operations-related expenses (including employee-related expenses, vendor services, vehicles and materials) | 0.1 |  |  | (6.8) |
Vegetation Management | (3.0) |  |  | (2.2) |
Total Base Electric Distribution (Non-Tracked Costs) | 3.4 |  |  | 3.3 |
Tracked Electric Costs (Electric Distribution and Electric Transmission) | 3.1 |  |  | 8.2 |
Total Electric Distribution and Electric Transmission | 6.5 |  |  | 11.5 |
Natural Gas Distribution: |  |  |
Base (Non-Tracked Costs) - Increase due primarily to higher uncollectible expense and employee-related expenses | 12.6 |  |  | 20.3 |
Tracked Costs | (4.1) |  |  | 5.1 |
Total Natural Gas Distribution | 8.5 |  |  | 25.4 |
Water Distribution | (1.3) |  |  | (4.0) |
Eversource Parent and Other Companies - other operations and maintenance | 1.0 |  |  | 1.6 |
Eliminations | (11.5) |  |  | (6.9) |
Total Operations and Maintenance | $ | 3.2 |  |  | $ | 27.6 |

Depreciation expen se increased for the three and six month periods due primarily to higher net plant in service balances.
Amortization expense includes the deferral of energy-related costs and other costs that are included in certain regulatory commission-approved cost tracking mechanisms. This deferral adjusts expense to match the corresponding revenues compared to the actual costs incurred. These costs are recovered from customers in rates and have no impact on earnings. Amortization expense also includes the amortization of cert ain costs as those costs are collected in rates.
The variance in Amortization for the three and six month periods is due primarily to the deferral adjustments of energy-related and other tracked costs at CL&P (included in the non-bypassable component of the FMCC mechanism and the SBC mechanism), NSTAR Electric and PSNH, which can fluctuate from period to period based on the timing of costs incurred and related rate changes to recover these costs. The CL&P non-bypassable FMCC retail rate increased and wholesale market sales revenues were higher in 2025 as compared to 2024. These higher collections resulted in a corresponding increase to amortization expense of $158.5 million and $501.1 million for the CL&P non-bypassable FMCC deferral adjustment for the three and six month periods, respectively.
Energy Efficiency Programs expense includes costs of various state energy policy initiatives and expanded energy efficiency programs that are recovered from customers in rates, most of which have no impact on earnings. Energy Efficiency Programs expense includes a deferral adjustment that reflects the actual costs of energy efficiency programs compared to the amounts billed to customers, which can fluctuate from period to period based on the timing of costs incurred and related rate changes to recover these costs. Energy Efficiency Programs expense de creased f or the three month period due primarily to the deferral adjustment, partially offset by higher program spending. Energy Efficiency Programs expense in creased f or the six month period due primarily to higher program spending.
Taxes Other Than Income Taxes expen se increased for t he three and six month periods due primarily to higher property taxes as a result of higher utility plant balances across our subsidiaries and higher mill rates at NSTAR Electric and higher Connecticut gross earnings taxes.
Interest Expense increased for the three and six month periods due primarily to the following:

(Millions of Dollars) | Three Months Ended |  | Six Months Ended
Long-term debt | $ | 13.1 |  |  | $ | 47.0 |
Absence in 2025 of capitalized interest as a result of the sale of our offshore wind projects in the third quarter of 2024 | 30.6 |  |  | 54.7 |
Capitalized AFUDC related to debt funds | (3.2) |  |  | 1.1 |
Amortization of debt discounts and premiums, net | 1.4 |  |  | 2.6 |
Regulatory deferrals | (24.8) |  |  | (38.7) |
Short-term notes payable | 5.1 |  |  | 5.1 |
RRBs | (0.4) |  |  | (0.8) |
Other | 0.1 |  |  | 0.9 |
Total Interest Expense | $ | 21.9 |  |  | $ | 71.9 |

55

Other Income, Net de creased for the three and six month periods due primarily to the following:

(Millions of Dollars) | Three Months Ended |  | Six Months Ended
Pension, SERP and PBOP Non-Service Income Components, Net of Deferred Portion | $ | 5.5 |  |  | $ | 10.3 |
Interest Income (primarily on regulatory deferrals) | (6.3) |  |  | (2.3) |
Capitalized AFUDC related to equity funds | 1.9 |  |  | (1.0) |
Equity in Earnings of Unconsolidated Affiliates | (18.4) |  |  | (20.2) |

Other | 0.5 |  |  | (1.1) |
Total Other Income, Net | $ | (19.9) |  |  | $ | (18.6) |

Income Tax Expense increased for the three month period due primarily to higher pre-tax earnings ($3.9 million), higher state taxes ($4.3 million), and a decrease in amortization of EDIT ($0.3 million), partially offset by a decrease in items that impact our tax rate as a result of regulatory treatment (flow-through items) and permanent differences ($7.2 million).
Income Tax Expense increased for the six month period due primarily to higher pre-tax earnings ($10.6 million), higher state taxes ($11.0 million), a decrease in amortization of EDIT ($1.0 million), and a higher share-based payment tax deficiency ($0.6 million), partially offset by a decrease in items that impact our tax rate as a result of regulatory treatment (flow-through items) and permanent differences ($19.1 million).

Operating Revenues
Sales Volumes: A summary of our retail electric GWh sales volumes is as follows:

| For the Six Months Ended June 30,
| 2025 |  | 2024 |  |  |  | Percentage Increase
CL&P | 9,881 |  |  | 9,732 |  |  |  |  | 1.5 | %
NSTAR Electric | 11,183 |  |  | 10,907 |  |  |  |  | 2.5 | %
PSNH | 3,846 |  |  | 3,784 |  |  |  |  | 1.6 | %

Fluctuations in retail electric sales volumes at PSNH impact earnings. For CL&P and NSTAR Electric, fluctuations in retail electric sales volumes do not impact earnings due to their respective regulatory commission-approved distribution revenue decoupling mechanisms.
Operating Revenues: Operating Revenues, which consist of base distribution revenues and tracked revenues further described below, increased $587.5 million at CL&P, $90.5 million at NSTAR Electric, and $37.7 million at PSNH for the six month period.
56

Base Distribution Revenues:
•CL&P's distribution revenues were flat for the six month period.
•NSTAR Electric's distribution revenues increased $26.6 million for the six month period due primarily to a base distribution rate increase effective January 1, 2025.
•PSNH's distribution revenues increased $35.6 million for the six month period due primarily to a temporary base distribution rate increase effective August 1, 2024.
Tracked Distribution Revenues: Tracked distribution revenues consist of certain costs that are recovered from customers in retail rates on a fully reconciling basis through regulatory commission-approved cost tracking mechanisms and therefore, recovery of these costs has no impact on earnings. Costs recovered through cost tracking mechanisms include, among others, energy supply procurement, state mandated energy purchase agreements and other energy-related costs, retail transmission charges, energy efficiency program costs, electric restructuring and stranded cost recovery revenues (including securitized RRB charges), certain capital tracking mechanisms for infrastructure improvements, and additionally for NSTAR Electric, pension and PBOP benefits, net metering for distributed generation, and solar-related programs. Revenues from certain of these cost tracking mechanisms also include certain incentives earned, return on capital tracking mechanisms, and carrying charges that are billed in rates to customers, which do impact earnings. Tracked revenues also include wholesale market sales transactions, such as sales of energy and energy-related products into the ISO-NE wholesale electricity market and the sale of RECs to various counterparties.
Customers have the choice to purchase electricity from their Eversource electric utility or from a competitive third party supplier. For customers who have contracted separately with these competitive suppliers, revenue is not recorded for the sale of the electricity commodity, as the utility is acting as an agent on behalf of the third party supplier. For customers that choose to purchase electric generation from CL&P, NSTAR Electric or PSNH, each utility purchases power on behalf of, and is permitted to recover the related energy supply cost without mark-up from, its customers, and records offsetting amounts in revenues and purchased power related to this energy supply procurement. CL&P, NSTAR Electric and PSNH each remain as the distribution service provider for all customers and charge a regulated rate for distribution delivery service recorded in revenues.
The variance in tracked distribution revenues for the six month period is due primarily to the following:

(Millions of Dollars) | CL&P |  | NSTAR Electric |  | PSNH
Retail Tariff Tracked Revenues: |  |  |  |  |
Energy supply procurement | $ | (109.0) |  |  | $ | (55.2) |  |  | $ | (9.0) |
CL&P NBFMCC | 344.1 |  |  | — |  |  | — |
CL&P SBC | 153.6 |  |  | — |  |  | — |
Retail transmission | (36.7) |  |  | 74.2 |  |  | 29.4 |
Other distribution tracking mechanisms | 58.0 |  |  | 22.7 |  |  | (22.6) |
Wholesale Market Sales Revenue | 176.1 |  |  | 30.8 |  |  | (1.3) |

Fluctuations in retail tariff tracked revenues are driven by adjustments to retail rates to recover costs and changes in sales volumes.
The decrease in energy supply procurement at CL&P for the six month period was driven by lower average prices, partially offset by higher average supply-related sales volumes. The decrease in energy supply procurement at NSTAR Electric and PSNH for the six month period was driven by lower average supply-related sales volumes and lower average prices.
The increase in CL&P’s NBFMCC revenues was driven by an increase in the retail Non-Bypassable Federally Mandated Congestion Charge (NBFMCC) rate. The CL&P NBFMCC rate includes the recovery of costs incurred under long-term state mandated energy purchase contracts with the Millstone and Seabrook nuclear power plants, net of the benefits received from selling this energy into the ISO-NE wholesale market. Effective September 1, 2023, CL&P’s average NBFMCC rate changed to $0.00293 per kWh. As a result of the April 2024 interim decision in the 2024 CL&P RAM filing, the average NBFMCC rate increased to $0.03906 per kWh effective July 1, 2024. As a result of the August final decision in the 2024 CL&P RAM filing, the average NBFMCC rate increased to $0.04290 per kWh effective September 1, 2024. The rate increases primarily resulted from higher net costs associated with power purchase agreements with the Millstone and Seabrook nuclear power plants.
The increase in electric distribution wholesale market sales revenue for the six month period was due primarily to higher average electricity market prices received for wholesale sales at CL&P. ISO-NE average market prices received for CL&P’s wholesale sales increased to an average price of $72.46 per MWh for the six months ended June 30, 2025, as compared to $32.90 per MWh for the same period in 2024, driven primarily by higher natural gas prices in New England. Volumes sold into the market were primarily from the sale of output generated by the Millstone PPA and Seabrook PPA with CL&P.
CL&P is required by regulation to purchase electric generation from Millstone and Seabrook under PURA-approved PPAs entered into in 2019. CL&P does not have legislative authority to use this purchased output to serve its customer load and therefore sells the energy into the wholesale market and uses the proceeds from the energy sales to offset the contract costs. The net cost or net sales amount is recovered from, or refunded to, customers in the non-bypassable component of the CL&P FMCC rate. Changes in CL&P’s NBFMCC retail revenues and CL&P’s wholesale market sales, as compared to the actual costs incurred, are deferred on the income statement by an offset to amortization expense.
Transmission Revenues: Transmission revenues increased $23.4 million at CL&P, $31.4 million at NSTAR Electric, and $19.8 million at PSNH for the six month period, due primarily to a higher transmission rate base as a result of our continued investment in our transmission infrastructure.
57

Eliminations: Eliminations are primarily related to the Eversource electric transmission revenues that are derived from ISO-NE regional transmission charges to the distribution businesses of CL&P, NSTAR Electric and PSNH that recover the costs of the wholesale transmission business in rates charged to their customers. The impact of eliminations decreased revenues by $22.0 million at CL&P, $40.5 million at NSTAR Electric, and $13.1 million at PSNH for the six month period.
Purchased Power and Transmission expense includes costs associated with providing electric generation service supply to all customers who have not migrated to third party suppliers, the cost of energy purchase contracts entered into as required by regulation, and transmission costs. These energy supply procurement costs, other energy-related costs, and transmission costs are recovered from customers in rates through commission-approved cost tracking mechanisms, which have no impact on earnings (tracked costs). The variance in Purchased Power and Transmission expense is due primarily to the following:

(Millions of Dollars) | CL&P |  | NSTAR Electric |  | PSNH
Energy supply procurement costs | $ | (107.2) |  |  | $ | (55.3) |  |  | $ | (9.4) |
Other electric distribution costs | (6.8) |  |  | 74.0 |  |  | (11.5) |
Transmission costs | (35.9) |  |  | 73.8 |  |  | 28.4 |
Eliminations | (22.0) |  |  | (40.5) |  |  | (13.1) |
Total Purchased Power and Transmission | $ | (171.9) |  |  | $ | 52.0 |  |  | $ | (5.6) |

The variance in energy supply procurement costs is offset in Operating Revenues (tracked energy supply procurement revenues). The variance in other electric distribution costs at CL&P is due to lower long-term contractual energy-related costs that are recovered in the non-bypassable component of the FMCC mechanism, at NSTAR Electric is due to an increase in the long-term renewable energy purchase contract cost deferral and higher net metering costs, and at PSNH is due to lower stranded costs resulting from higher Regional Greenhouse Gas Initiative (RGGI) proceeds received, which are credited back to customers at PSNH.
Included in transmission costs are charges that recover the cost of transporting electricity over high-voltage lines from generation facilities to substations, including costs allocated by ISO-NE to maintain the wholesale electric market.
•The decrease in transmission costs at CL&P was due primarily to a decrease resulting from the retail transmission cost deferral, which reflects the actual costs of transmission service compared to estimated amounts billed to customers. The decrease was partially offset by an increase in costs billed by ISO-NE that support regional grid investments.
•The increase in transmission costs at NSTAR Electric and PSNH was due primarily to an increase in costs billed by ISO-NE that support regional grid investments, an increase in Local Network Service charges, which reflect the cost of transmission service provided by Eversource over our local transmission network and an increase in the retail transmission cost deferral.
Operations and Maintenance expense includes tracked costs and costs that are part of base distribution rates with changes impacting earnings (non-tracked costs). The variance in Operations and Maintenance expense is due primarily to the following:

(Millions of Dollars) | CL&P |  | NSTAR Electric |  | PSNH
Base Electric Distribution (Non-Tracked Costs): |  |  |  |  |
Uncollectible Expense | $ | 3.7 |  |  | $ | 2.3 |  |  | $ | 0.1 |
Storm costs | 2.1 |  |  | (4.7) |  |  | 0.7 |
Shared corporate costs (including IT system depreciation at Eversource Service) | 1.2 |  |  | 2.9 |  |  | 0.8 |
Vegetation Management | (7.6) |  |  | (3.6) |  |  | 9.0 |
General corporate costs (including vendor services in corporate areas, insurance, fees and assessments) | (7.2) |  |  | 8.0 |  |  | 2.4 |
Operations-related expenses (including employee-related expenses, vendor services, vehicles and materials) | (1.2) |  |  | (1.8) |  |  | (3.8) |
Total Base Electric Distribution (Non-Tracked Costs) | (9.0) |  |  | 3.1 |  |  | 9.2 |
Total Tracked Costs | 15.7 |  |  | 2.1 |  |  | (9.6) |
Total Operations and Maintenance | $ | 6.7 |  |  | $ | 5.2 |  |  | $ | (0.4) |

Depreciation expense increased f or the six month period for CL&P, NSTAR Electric and PSNH due to higher net plant in service balances.
Amortization of Regulatory Assets/(Liabilities), Net expense includes the deferral of energy-related costs and other costs that are included in certain regulatory commission-approved cost tracking mechanisms. This deferral adjusts expense to match the corresponding revenues compared to the actual costs incurred. These costs are recovered from customers in rates and have no impact on earnings. Amortization expense also includes the amortization of certain costs as those costs are collected in rates. The variance in Amortization of Regulatory Assets/(Liabilities), Net for the six month period is due primarily to the following:
•The variance at CL&P was due primarily to the deferral adjustment of energy-related and other tracked costs that are included in the non-bypassable component of the FMCC mechanism and the SBC mechanism, which can fluctuate from period to period based on the timing of costs incurred and related rate changes to recover these costs. The CL&P non-bypassable FMCC retail rate increased and wholesale market sales revenues were higher in 2025 as compared to 2024. These higher collections resulted in a corresponding increase to amortization expense of $501.1 million for the non-bypassable FMCC deferral adjustment for the six month period.
58

•The variance at NSTAR Electric was due primarily to the deferral adjustment of costs included in the solar facilities and advanced metering infrastructure regulatory mechanisms, partially offset by the deferral adjustment of energy-related and other tracked costs that are included in the grid modernization regulatory mechanism and higher amortization of storm costs recovered in rates.
•The variance at PSNH was due to the deferral adjustment of energy related and other tracked costs.
Energy Efficiency Programs expense includes costs of various state energy policy initiatives and expanded energy efficiency programs that are recovered from customers in rates, most of which have no impact on earnings. Energy Efficiency Programs expense includes a deferral adjustment that reflects the actual costs of energy efficiency programs compared to the amounts billed to customers, which can fluctuate from period to period based on the timing of costs incurred and related rate changes to recover these costs. The variance in Energy Efficiency Programs expense for the six month period is due primarily to the following:
•The increase at CL&P was due to the deferral adjustment and higher program spending.
•The decrease at NSTAR Electric was due to the deferral adjustment, partially offset by higher program spending.
•The increase at PSNH was due to higher program spending, partially offset by the deferral adjustment.
Taxes Other Than Income Taxes - the variance is due primarily to the following:
•The increase at CL&P was due to higher Connecticut gross earnings taxes and higher property taxes as a result of higher utility plant balances.
•The increase at NSTAR Electric was due to higher property taxes as a result of higher utility plant balances and higher mill rates.
•The increase at PSNH was due to higher property taxes as a result of higher utility plant balances.
Interest Expense - the variance is due primarily to the following:

(Millions of Dollars) | CL&P |  | NSTAR Electric |  | PSNH
Long-term debt | $ | 12.2 |  |  | $ | 26.4 |  |  | $ | 4.3 |

Total Other Income, Net | $ | (9.3) |  |  | $ | (1.5) |  |  | $ | 9.7 |

Income Tax Expense - the variance is due primarily to the following:
•The increase at CL&P was due primarily to higher pre-tax earnings ($7.7 million), a decrease in amortization of EDIT ($1.0 million), higher share-based payment tax deficiency ($0.2 million), higher state taxes ($2.8 million), and an increase in items that impact our tax rate as a result of regulatory treatment (flow-through items) and permanent differences ($0.2 million).
•The increase at NSTAR Electric was due primarily to higher pre-tax earnings ($4.9 million), higher state taxes ($1.1 million) and higher share-based payment tax deficiency ($0.4 million), partially offset by a decrease in items that impact our tax rate as a result of regulatory treatment (flow-through items) and permanent differences ($1.6 million).
•The increase at PSNH was due primarily to higher pre-tax earnings ($8.6 million), higher state taxes ($2.2 million) and higher share-based payment tax deficiency ($0.1 million), partially offset by an increase in amortization of EDIT ($0.3 million) and a decrease in items that impact our tax rate as a result of regulatory treatment (flow-through items) and permanent differences ($0.2 million).
EARNINGS SUMMARY
CL&P's earnings increased $24.9 million for the six month period due primarily to an increase in transmission earnings driven primarily by a higher transmission rate base and lower interest expense, higher revenues from its capital tracking mechanism due to increased electric system improvements, and lower operations and maintenance expense. The earnings increase was partially offset by higher depreciation expense, lower net interest income on regulatory deferrals, and higher property tax expense.
59

NSTAR Electric's earnings increased $18.5 million for the six month period due primarily to higher revenues as a result of the base distribution rate increase effective January 1, 2025, an increase in transmission earnings driven primarily by a higher transmission rate base and lower interest expense, and higher earnings from its AMI tracking mechanism. The earnings increase was partially offset by higher property tax expense, higher interest expense on long-term debt, and higher operations and maintenance expense.
PSNH's earnings increased $30.4 million for the six month period due primarily to higher revenues as a result of the base distribution rate increase effective August 1, 2024 and an increase in transmission earnings driven primarily by a higher transmission rate base and lower interest expense. The earnings increase was partially offset by higher operations and maintenance expense, higher interest expense on long-term debt, and higher depreciation expense.
LIQUIDITY
Cash Flows: CL&P had cash flows provided by operating activities of $753.6 million for the six months ended June 30, 2025, as compared to $109.8 million in the same period of 2024. The increase in operating cash flows was due primarily to an improvement in regulatory recoveries driven primarily by the timing of collections for the non-bypassable FMCC and the SBC regulatory tracking mechanisms. The CL&P non-bypassable FMCC retail rate increased as a result of the 2024 RAM decision and the net Millstone and Seabrook contract cash flows were higher in 2025 as compared to 2024. These higher collections resulted in an improvement to operating cash flows of $501.1 million for the six month period. The impacts of regulatory collections are included in both Regulatory Recoveries and Amortization of Regulatory Assets/(Liabilities), Net on the statements of cash flows. Operating cash flows were also favorably impacted by the timing of cash collections on our accounts receivable, a decrease of $47.1 million in cash payments to vendors for storm costs, and the timing of other working capital items. These favorable impacts were partially offset by a decrease of $223.4 million in operating cash flows due to income tax payments made in 2025 compared to income tax refunds received in 2024 and the timing of cash payments made on our accounts payable.
NSTAR Electric had cash flows provided by operating activities of $393.6 million for the six months ended June 30, 2025, as compared to $341.4 million in the same period of 2024. The increase in operating cash flows was due primarily to an improvement in regulatory recoveries driven primarily by the timing of collections for energy supply costs, net metering costs and other regulatory tracking mechanisms, a decrease of $102.2 million in cash payments to vendors for storm costs, and the timing of cash payments made on our accounts payable. The impacts of regulatory collections are included in both Regulatory Recoveries and Amortization of Regulatory Assets, Net on the statements of cash flows. These favorable impacts were partially offset by the timing of cash collections on our accounts receivable, an increase of $32.0 million in income tax payments made in 2025 compared to 2024, an increase in cost of removal expenditures, and the timing of other working capital items.
PSNH had cash flows provided by operating activities of $191.9 million for the six months ended June 30, 2025, as compared to $76.5 million in the same period of 2024. The increase in operating cash flows was due primarily to an improvement in regulatory recoveries driven primarily by the timing of collections for retail and wholesale transmission costs and other regulatory tracking mechanisms, a decrease of $51.1 million in cash payments to vendors for storm costs, the timing of cash payments made on our accounts payable, a decrease in cost of removal expenditures, and the timing of other working capital items. The impacts of regulatory collections are included in both Regulatory Recoveries and Amortization of Regulatory Assets, Net on the statements of cash flows. These favorable impacts were partially offset by a decrease of $53.1 million in operating cash flows due to income tax payments made in 2025 compared to income tax refunds received in 2024 and the timing of cash collections on our accounts receivable.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Market Risk Information
Commodity Price Risk Management: Our regulated companies enter into energy contracts to serve our customers, and the economic impacts of those contracts are passed on to our customers. Accordingly, the regulated companies have no exposure to loss of future earnings or fair values due to these market risk-sensitive instruments. Eversource's Energy Supply Risk Committee, comprised of senior officers, reviews and approves all large-scale energy related transactions entered into by its regulated companies.
Other Risk Management Activities
Interest Rate Risk Management: Interest rate risk is associated with changes in interest rates for our outstanding long-term debt. Our interest rate risk is significantly reduced as typically all or most of our debt financings have fixed interest rates. As of June 30, 2025, all of our long-term debt was at a fixed interest rate.
Credit Risk Management: Credit risk relates to the risk of loss that we would incur as a result of non-performance by counterparties pursuant to the terms of our contractual obligations. We serve a wide variety of customers and transact with suppliers that include IPPs, industrial companies, natural gas and electric utilities, oil and natural gas producers, financial institutions, and other energy marketers. Margin accounts exist within this diverse group, and we realize interest receipts and payments related to balances outstanding in these margin accounts. This wide customer and supplier mix generates a need for a variety of contractual structures, products and terms that, in turn, require us to manage the portfolio of market risk inherent in those transactions in a manner consistent with the parameters established by our risk management process.
60

Our regulated companies are subject to credit risk from certain long-term or high-volume supply contracts with energy marketing companies. Our regulated companies manage the credit risk with these counterparties in accordance with established credit risk practices and monitor c ontracting risks, including credit risk. As of June 30, 2025, our regulated companies held collateral (letters of credit or cash) of $19.0 million from counterparties related to our standard service contracts. As of June 30, 2025, Eversource had $14.8 million of cash pos ted with ISO-NE related to energy transactions.
We have provided additional disclosures regarding interest rate risk management and credit risk management in Part II, Item 7A, "Quantitative and Qualitative Disclosures about Market Risk," in Eversource's 2024 Form 10-K, which is incorporated herein by reference. There have been no additional risks identified and no material changes with regard to the items previously disclosed in the Eversource 2024 Form 10-K.
ITEM 4. CONTROLS AND PROCEDURES
Management, on behalf of Eversource, CL&P, NSTAR Electric and PSNH, evaluated the design and operation of the disclosure controls and procedures as of June 30, 2025 to determine whether they are effective in ensuring that the disclosure of required information is made timely and in accordance with the Securities Exchange Act of 1934 and the rules and regulations of the SEC. This evaluation was made under management's supervision and with management's participation, including the principal executive officer and principal financial officer as of the end of the period covered by this Quarterly Report on Form 10-Q. There are inherent limitations of disclosure controls and procedures, including the possibility of human error and the circumventing or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. The principal executive officer and principal financial officer have concluded, based on their review, that the disclosure controls and procedures of Eversource, CL&P, NSTAR Electric and PSNH are effective to ensure that information required to be disclosed by us in reports filed under the Securities Exchange Act of 1934 (i) is recorded, processed, summarized, and reported within the time periods specified in SEC rules and regulations and (ii) is accumulated and communicated to management, including the principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosures.
There have been no changes in internal controls over financial reporting for Eversource, CL&P, NSTAR Electric and PSNH during the quarter ended June 30, 2025 that have materially affected, or are reasonably likely to materially affect, internal controls over financial reporting.
