(a)The Companies’ policy is to review the fair value hierarchy and recognize transfers into and transfers out of the levels at the end of each reporting period. Transfers out of Level 3 represent assets and liabilities that were previously classified as Level 3 for which the inputs became observable for classification in Level 2. The inputs are now observable because of availability of observable market data due to the decrease in the terms of certain contracts from beyond three years to less than three years.

(b)Level 2 assets and liabilities include investments held in the deferred compensation plan and/or non-qualified retirement plans, exchange-traded contracts where there is insufficient market liquidity to warrant inclusion in Level 1, and certain over-the-counter derivative instruments for electricity, refined products and natural gas. Derivative instruments classified as Level 2 are valued using industry standard models that incorporate corroborated observable inputs, such as pricing services or prices from similar instruments that trade in liquid markets, time value and volatility factors.

(c)The accounting rules for fair value measurements and disclosures require consideration of the impact of nonperformance risk (including credit risk) from a market participant perspective in the measurement of the fair value of assets and liabilities. At June 30, 2026 and December 31, 2025, the Companies determined that nonperformance risk would have no material impact on their financial position or results of operations.

(d)Amounts represent the impact of legally-enforceable master netting agreements that allow the Companies to net gain and loss positions and cash collateral held or placed with the same counterparties.

Summary of Significant Accounting Policies and Other Matters

Accounting Policies [Abstract]

Summary of Significant Accounting Policies and Other Matters

Accounting Policies

The accounting policies of Con Edison and its subsidiaries conform to generally accepted accounting principles in the United States of America (GAAP). For the Utilities, these accounting principles include the accounting rules for regulated operations and the accounting requirements of the Federal Energy Regulatory Commission (FERC) and the state regulators having jurisdiction.

Investments

Con Edison's investments consist primarily of the fair value of the Utilities' supplemental retirement income plan and deferred income plan assets.

In April 2026, CECONY and Con Edison Transmission entered into an agreement to sell their interests in Honeoye Storage Corporation (Honeoye) for $5 million in aggregate, of which approximately $1.5 million was attributed to CECONY, before certain closing adjustments and expenses. The closing is expected to occur following approval by the NYSPSC.

Investment in Mountain Valley Pipeline, LLC (MVP)

During the first quarter of 2026, Con Edison Transmission completed the sale of its approximately 6.6 percent equity interest in MVP to the two founding members of MVP for total aggregate consideration of $357.5 million, before certain closing adjustments and expenses. Prior to the sale, Con Edison recorded its pro rata share of earnings from its equity interest in MVP, adjusted for accretion of the basis difference and income taxes, on its consolidated income statement of $7 million ($5 million after-tax) and $15 million ($11 million after-tax) for the six months ended June 30, 2026 and 2025, respectively. See Note Q for further information.

Reclassification

Certain prior period amounts have been reclassified to conform with the current period presentation.

Earnings Per Share

Con Edison presents basic and diluted earnings per share (EPS) on the face of its consolidated income statement. Basic EPS is calculated by dividing earnings available to common shareholders (“Net income for common stock” on Con Edison’s consolidated income statement) by the weighted average number of Con Edison common shares outstanding during the period. In the calculation of diluted EPS, weighted average shares outstanding are increased for additional shares that would be outstanding if potentially dilutive securities were converted to common stock.

Potentially dilutive securities for Con Edison consist of restricted stock units and deferred stock units for which the average market price of the common shares for the period was greater than the estimated vesting price, and its common shares that are subject to forward sale agreements (see Note C). Before the issuance of common shares upon settlement of the forward sale agreements, the shares will be reflected in the company’s diluted earnings per share calculations using the treasury stock method. Under this method, the number of common shares used in calculating diluted earnings per share is deemed to be increased by the excess, if any, of the number of shares that would be issued upon physical settlement of the forward sale agreements over the number of shares that could be purchased by the company in the market (based on the average market price during the period) using the proceeds due upon physical settlement (based on the adjusted forward sale price at the end of the reporting period).

For the three and six months ended June 30, 2026 and 2025, basic and diluted EPS for Con Edison are calculated as follows:


	For the Three Months Ended June 30,		For the Six Months Ended June 30,
(Millions of Dollars, except per share amounts/Shares in Millions)	2026	2025	2026	2025
Net income for common stock	$308	$246	$1,232	$1,038
Weighted average common shares outstanding – basic	368.8	360.4	365.6	354.5
Add: Incremental shares attributable to effect of potentially dilutive securities	1.2	1.3	1.2	1.3
Adjusted weighted average common shares outstanding – diluted	370.0	361.7	366.8	355.8
Net Income per common share – basic	$0.83	$0.68	$3.37	$2.93
Net Income per common share – diluted	$0.83	$0.68	$3.36	$2.92

The computation of diluted EPS for the three and six months ended June 30, 2026 excluded an immaterial amount of performance share awards because of their anti-dilutive effect.

Reconciliation of Cash, Temporary Cash Investments and Restricted Cash

Cash, temporary cash investments and restricted cash are presented on a combined basis in the Companies’ consolidated statements of cash flows. At June 30, 2026 and 2025, Con Edison and CECONY did not have material restricted cash balances.

Variable Interest Entities

The accounting rules for consolidation address the consolidation of a variable interest entity (VIE) by a business enterprise that is the primary beneficiary. A VIE is an entity that does not have a sufficient equity investment at risk to permit it to finance its activities without additional subordinated financial support, or whose equity investors lack the characteristics of a controlling financial interest. The primary beneficiary is the business enterprise that has the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and either absorbs a significant amount of the VIE’s losses or has the right to receive benefits that could be significant to the VIE.

The Companies enter into arrangements including leases, partnerships and electricity purchase agreements, with various entities. As a result of these arrangements, the Companies retain or may retain a variable interest in these entities.

CECONY has an ongoing long-term electricity purchase agreement with Brooklyn Navy Yard Cogeneration Partners, LP, a potential VIE. In 2025, a request was made of this counterparty for information necessary to determine whether the entity was a VIE and whether CECONY is the primary beneficiary; however, the information was not made available. The payments for this contract constitute CECONY’s maximum exposure to loss with respect to the potential VIE.

One Big Beautiful Bill Act

On July 4, 2025, the One Big Beautiful Bill Act (OBBBA) was signed into law, containing a broad range of tax reform provisions, including extending and modifying certain key provisions of the federal Tax Cuts and Jobs Act of 2017, as enacted on December 22, 2017 and expanding certain incentives under the federal Inflation Reduction Act (IRA), as enacted on August 16, 2022 while accelerating the phase-out of solar and wind credits. The Companies have assessed the potential impacts of the OBBBA and any such assessments may be impacted by future guidance to be issued by the Department of Treasury. However, based on management’s assessment, the provisions in the OBBBA have not had, and are not expected to have, a material impact on the Companies’ financial position, results of operations or liquidity.

Corporate Alternative Minimum Tax

On August 16, 2022, the IRA was signed into law and implemented a new corporate alternative minimum tax (CAMT) that imposes a 15 percent tax on modified GAAP net income. Pursuant to the IRA, corporations are entitled to a tax credit (minimum tax credit) to the extent the CAMT liability exceeds the regular tax liability. This amount can be carried forward indefinitely and used in future years when regular tax liability exceeds the CAMT liability.

Beginning in 2024, based on the existing statute, the Companies are subject to and report the CAMT in their Consolidated Income Statements, Consolidated Statements of Cash Flows and the Consolidated Balance Sheets. At June 30, 2026, Con Edison accrued a CAMT liability of $72 million ($68 million of which is for CECONY) before the application of general business credits, with an offsetting deferred tax asset representing the minimum tax credit carryforward. The deferred tax asset related to the minimum tax credit carryforward will be realized to the extent the Companies’ consolidated deferred tax liabilities exceed the minimum tax credit carryforward. The Companies’ deferred tax liabilities are expected to exceed the minimum tax credit carryforward for the foreseeable future and thus no valuation allowance is required.

On February 18, 2026, the Internal Revenue Service and the Department of Treasury issued Notice 2026-7, which provides additional interim guidance regarding the application of the CAMT and allows the Companies to deduct certain repair expenditures as a reduction to the Companies’ modified GAAP net income. This interim guidance is retroactive to the beginning of the IRA provisions in calculating the Companies’ CAMT liability. In the six months ended June 30, 2026, Con Edison reduced its CAMT credit carryforward by $205 million ($213 million of which is for CECONY) and increased its general business tax credit carryforward by approximately $154 million as a result of adopting the interim guidance for the 2024 and 2025 tax years. This guidance will also reduce the Companies’ CAMT liability going forward. The Companies are continuing to assess the impacts of the IRA on their financial statements and will update estimates based on future guidance to be issued by the Department of the Treasury.

New York Legislation

In April 2021, New York passed a law that increased the corporate franchise tax rate on business income from 6.5 percent to 7.25 percent, retroactive to January 1, 2021, for taxpayers with taxable income greater than $5 million. The law also reinstated the business capital tax at 0.1875 percent, not to exceed a maximum tax liability of $5 million per taxpayer. New York requires a corporate franchise taxpayer to calculate and pay the highest amount of tax under the three alternative methods: a tax on business income; a tax on business capital; or a fixed dollar minimum. The provisions to increase the corporate franchise tax rate and reinstate a capital tax were scheduled to expire after 2023. In May 2023, New York passed a law that extended the increase in the corporate franchise tax rate from 6.5 percent to 7.25 percent for an additional three years, through tax year 2026 and extended the business capital tax through tax year 2026. New York also passed a law establishing a permanent rate of 30 percent for the metropolitan transportation business tax surcharge. In May 2026, New York passed a law that extended the increase in the corporate franchise tax rate from 6.5 percent to 7.25 percent for an additional three years, through tax year 2029 and extended the business capital tax through tax year 2029. Con Edison does not expect to be subject to the higher tax rate of 7.25 percent in 2026.

Uncertain Tax Positions

Under the accounting rules for income taxes, the Companies are not permitted to recognize the tax benefit attributable to a tax position unless such position is more likely than not to be sustained upon examination by taxing authorities, including resolution of any related appeals and litigation processes, based solely on the technical merits of the position.

At June 30, 2026, the estimated uncertain tax positions for Con Edison were $10 million ($6 million of which is for CECONY). For the six months ended June 30, 2026, Con Edison recognized $0.9 million of income tax expense related to current year positions ($0.8 million of which is for CECONY). The total amount of unrecognized tax benefits, if recognized, that would reduce Con Edison’s effective tax rate is $10 million ($9 million, net of federal taxes) with $6 million attributable to CECONY.

The Companies recognize interest on liabilities for uncertain tax positions in interest expense and would recognize penalties, if any, in operating expenses in the Companies’ consolidated income statements. For the six months ended June 30, 2026 and 2025, the Companies recognized an immaterial amount of interest expense and no penalties for uncertain tax positions in their consolidated income statements. At June 30, 2026 and December 31, 2025, the Companies recognized an immaterial amount of accrued interest on their consolidated balance sheets.

Accounting Changes and Error Corrections [Abstract]
New Financial Accounting Standards	New Financial Accounting Standards In May 2026, the Financial Accounting Standards Board (FASB) issued guidance on accounting for Environmental Credits and Environmental Credit Obligations (Topic 818) through ASU 2026-02. The guidance addresses accounting for and disclosure of environmental credits and environmental credit obligations. It provides recognition, measurement, presentation, and disclosure requirements for all entities that generate, purchase, or receive environmental credits or have a regulatory compliance obligation that may be settled with environmental credits. The amendments in ASU 2026-02 are effective for fiscal years beginning after December 15, 2027, and interim reporting periods within those fiscal years, with early adoption permitted. The Companies are evaluating the potential impact of this new standard on their financial position, results of operations and liquidity.

- Definition

The entire disclosure for change in accounting principle. Includes, but is not limited to, nature, reason, and method of adopting amendment to accounting standards or other change in accounting principle.

Regulated Operations [Abstract]

Regulatory Matters

Rate Plans

CECONY – Steam

In November 2025, CECONY filed a request with the NYSPSC for a steam rate increase of $66 million, effective November 1, 2026. The filing reflects a return on common equity of 9.9 percent and a common equity ratio of 48 percent. The filing includes supplemental information regarding steam rate plans for November 2027 through October 2028, and November 2028 through October 2029, which the company is not requesting but would consider through settlement discussions. For purposes of illustration, rate increases of $50 million and $50 million effective November 2027 and 2028, respectively, were calculated based on an assumed return on common equity of 9.9 percent and a common equity ratio of 48 percent.

In March 2026, the New York State Department of Public Service (NYSDPS) submitted testimony in the pending steam rate case proceeding supporting a steam rate increase of $18 million, reflecting, among other things, a 9.3 percent return on common equity and a common equity ratio of 47.5 percent.

RECO

In June 2026, the New Jersey Board of Public Utilities (NJBPU) approved an electric rate increase, effective July 1, 2026, of $15.25 million and a 9.6 percent return on equity for RECO. In addition, RECO provided a company-funded bill credit for residential customers of $0.5 million in July 2026. The following table contains a summary of the terms of the distribution rate plan.

In June 2026, as part of New Jersey State’s Fiscal Year 2027 Budget, the state allocated $10.68 million to provide bill credits to eligible residential customers of RECO.

Also in June 2026, the NJBPU issued orders that established a residential universal bill credit and a residential energy assistance credit, in an aggregate amount of approximately $2 million for qualified customers of RECO to be funded by New Jersey.

Other Regulatory Matters

In July 2026, the NYSPSC ordered New York utilities, including CECONY and O&R, to show cause why the NYSPSC should not commence a prudence review and an administrative penalty proceeding related to electric vehicle make‑ready program data collection and reporting deficiencies. The Utilities are unable to estimate the amount or range of possible loss related to this matter.

In May 2026, a woman died after falling into a manhole with a dislodged cover in Midtown Manhattan. A lawsuit has been filed against CECONY seeking unspecified compensatory and punitive damages under multiple causes of action. CECONY has provided information to the NYSDPS and has notified its insurers of the incident and lawsuit. CECONY believes that its applicable insurance policies will satisfy any liability it may have in connection with the lawsuit, to the extent such liability exceeds the required self-retention amount, which amount is not material. CECONY is unable to estimate the amount or range of loss and cannot predict whether any other legal or regulatory actions may arise concerning this matter.

In January 2023, CECONY initiated a review of welds on certain gas and steam mains following the company’s discovery of a leak from a gas main weld in Queens, New York. During the course of its review thus far, CECONY discovered non-conforming gas and steam main welds. The non-conforming welds are not expected to have a significant impact on operations. New York regulations require utilities to perform and record weld films for certain gas and steam main welds. Upon reviewing these films, CECONY determined that in some instances third-party contractors engaged in misconduct by substituting duplicate weld films for different welds, while another third-party contractor had created poor quality weld films. CECONY voluntarily disclosed its initial review and findings to the NYSDPS which, in turn, initiated its own investigation into CECONY’s compliance with weld requirements under the New York State Public Service Law and the prudence of CECONY’s oversight of the weld testing process that could result in adverse regulatory action against the company. CECONY continues to investigate this matter, is remediating and monitoring non-conforming welds and continues to cooperate with the NYSDPS in its investigation. During the time period CECONY disclosed the issue to the NYSDPS, it also reported the contractors’ misconduct to law enforcement. In August 2025, two employees of the third-party contractors were indicted in the U.S. District Court for the Southern District of New York for wire fraud arising out of their scheme to defraud CECONY. Given the nature of the non-conforming welds identified, CECONY does not anticipate significant impact to the operation of its gas and steam mains. CECONY's authorized gas rate plan for the three-year period January 2026 through December 2028 provides that $33.3 million in annual gas revenue requirement ($100 million in aggregate from 2026 through 2028) will be recovered through a rate adjustment mechanism that is subject to refund to customers relating to this matter. NYSDPS’ testimony in the pending steam rate case recommended that recovery of $0.5 million of CECONY's steam revenue requirement through the rate adjustment mechanism be subject to refund for the welds matter. CECONY is unable to estimate the amount or range of its possible loss related to this matter.

In January 2018, the NYSPSC issued an order initiating a focused operations audit of the Utilities’ financial accounting for income taxes. The audit is investigating the Utilities’ inadvertent understatement of a portion, the amount of which may be material, of their calculation of total federal income tax expense for ratemaking purposes related to the calculation of plant retirement-related cost of removal. As a result of such understatement, the Utilities accumulated significant income tax regulatory assets ($1,016 million and $7 million for CECONY and O&R, respectively, as of June 30, 2026 and $1,049 million and $10 million for CECONY and O&R, respectively, as of December 31, 2025) which are not earning a return. While the Utilities have properly calculated and paid their federal income taxes and there is no uncertain tax position related to this matter, this understatement of historical income tax expense materially reduced the amount of revenue collected from the Utilities' customers in the past relative to what it should have been. The Utilities’ rate plans have reflected the correct amount of federal income taxes recoverable from customers, including a proportionate recovery of the regulatory asset, beginning with O&R’s rate plans effective November 2015, CECONY’s electric and gas rate plans effective January 2017, and CECONY’s steam plan effective November 2023. As part of the audit, the Utilities plan to pursue a private letter ruling from the Internal Revenue Service (IRS) confirming that the Utilities’ inadvertent understatement of prior years’ income tax expense constitutes a normalization violation that can be cured through an increase in future years’ revenue requirements until such time as the regulatory asset is fully recovered in rates, and not through a write-down of all or a portion of the Utilities’ regulatory asset. Under Accounting Standards Codification Topic (ASC) 740, the Utilities recorded an unfunded deferred federal income tax liability (with a gross-up amount) and a corresponding regulatory asset. The income tax regulatory assets are netted against the related regulatory liability for future income tax and are shown in the line “Future income tax” in the following table of Regulatory Assets and Liabilities and on the Companies’ consolidated balance sheets in the line “Regulatory liabilities.” Management’s assessment is that the income tax regulatory assets as of June 30, 2026 are probable of collection through future rates. The IRS provides safe harbor relief for inadvertent normalization violations through the jurisdictional rate setting process of including in rates adequate revenue to fully recover the deferred tax balance. However, the Utilities would record a liability or impair a portion of the regulatory assets associated with this understatement if the NYSPSC were to issue an order that required the Utilities to write off all or a portion of their existing regulatory asset. The Utilities are unable to estimate the amount or range of their possible loss related to this matter. At June 30, 2026, the Utilities had not accrued a liability related to this matter.

* See "Other Regulatory Matters" above.

(a) Energy Efficiency and Other Clean Energy Programs represent programs designed to increase energy efficiency achievements and other clean energy transformation efforts.

(c) Property tax reconciliation represents the amount deferred between actual property taxes incurred and the level included in rates subject to the provisions of the respective rate plans.

(d) Deferred storm costs represent response and restoration costs, other than capital expenditures, in connection with major storms that were deferred by the Utilities.

(e) Allowance for cost of removal less salvage represents cash previously collected from customers to fund future anticipated removal expenditures.

(f) Unrecognized pension and other postretirement costs represent the deferrals associated with the accounting rules for retirement benefits.

In general, the Utilities receive or are being credited with a return at the Other Customer-Provided Capital rate for regulatory assets that have not been included in rate base, and receive or are being credited with a return at the pre-tax weighted average cost of capital once the asset is included in rate base. Similarly, the Utilities pay to or credit customers with a return at the Other Customer-Provided Capital rate for regulatory liabilities that have not been included in rate base, and pay to or credit customers with a return at the pre-tax weighted average cost of capital once the liability is included in rate base. The Other Customer-Provided Capital rate was 4.70 percent and 4.75 percent for the 2026 and 2025 rate years, respectively.

In general, the Utilities are receiving or being credited with a return on their regulatory assets for which a cash outflow has been made ($3,662 million and $3,421 million for Con Edison, and $3,418 million and $3,193 million for CECONY at June 30, 2026 and December 31, 2025, respectively). Regulatory liabilities are treated in a consistent manner. Regulatory assets of RECO for which a cash outflow has been made ($46 million at June 30, 2026 and $41 million at December 31, 2025) are not receiving or being credited with a return. RECO recovers regulatory assets over a period of up to four years or until they are addressed in its next base rate case in accordance with the rate provisions approved by the NJBPU. Regulatory liabilities are treated in a consistent manner.

Regulatory assets that represent future financial obligations and were deferred in accordance with the Utilities’ rate plans or orders issued by state regulators do not earn a return until such time as a cash outlay has been made. Regulatory liabilities are treated in a consistent manner. At June 30, 2026 and December 31, 2025, regulatory assets for Con Edison and CECONY that did not earn a return consisted of the following items:

Regulatory Assets Not Earning a Return*

*This table presents regulatory assets not earning a return for which no cash outlay has been made.

The recovery periods for regulatory assets for which a cash outflow has not been made and that do not earn a return have not yet been determined, except as noted below, and are expected to be determined pursuant to the Utilities’ future rate plans to be filed or orders issued by the state regulators in connection therewith.

The deferral for revenue taxes represents the New York State metropolitan transportation business tax surcharge on the cumulative temporary differences between the book and tax basis of assets and liabilities of the Utilities, as well as the difference between taxes collected and paid by the Utilities to fund mass transportation. The Utilities recover the majority of the revenue taxes over the remaining book lives of the electric and gas plant assets, as well as the steam plant assets for CECONY.

The Utilities recover deferred derivative losses – short-term within one year, and long-term generally within three years.

The Utilities recover unrecognized pension and other postretirement costs over 10 years, and the portion of investment gains or losses is recognized in expense over 15 years, pursuant to NYSPSC policy.

Components of net periodic benefit credit other than service cost are presented outside of operating income on the Companies’ consolidated income statements, and only the service cost component is eligible for capitalization. Accordingly, the service cost components are included in the line "Other operations and maintenance" and the non-service cost components are included in the lines "Other income" or "Other deductions" in the Companies' consolidated income statements.

Expected Contributions

Based on estimates as of June 30, 2026, the Companies expect to make contributions to the pension plans during 2026 of $58 million (of which $52 million is to be made by CECONY). The Companies’ policy is to fund the total periodic benefit cost of the qualified plan to the extent tax deductible and to also contribute to the non-qualified supplemental pension plans. An immaterial amount of funding is anticipated for the qualified plan during 2026, and during the first six months of 2026, the Companies contributed $12 million to the non-qualified supplemental pension plans, $11 million of which was contributed by CECONY. CECONY also contributed $4 million to the external trust for its non-qualified supplemental plan.

(a)Derivative instruments and collateral were offset on the consolidated balance sheet as applicable under the accounting rules. The Companies enter into master agreements for their commodity derivatives. These agreements typically provide offset in the event of contract termination. In such cases, generally the non-defaulting party’s payable will be offset by the defaulting party’s payable. The non-defaulting party will customarily notify the defaulting party within a specific time period and come to an agreement on the early termination amount.

(b)At June 30, 2026, collateral and margin deposits for Con Edison and CECONY were classified as derivative assets of $3 million and $2 million, and as derivative liabilities of $(4) million and $(2) million, respectively. At December 31, 2025, collateral and margin deposits for Con Edison and CECONY were classified as derivative assets of $1 million and an immaterial amount, respectively, and as derivative liabilities of $(16) million and $(14) million, respectively. These amounts are presented on the consolidated balance sheets, but not included in the table. Margin is collateral, typically cash, that the holder of a derivative instrument is required to deposit in order to transact on an exchange and to cover its potential losses with its broker or the exchange.

(b)Unrealized net deferred gains on electric and gas derivatives for the Utilities increased as a result of higher electric and gas commodity prices during the three months ended June 30, 2026. Upon settlement, short-term deferred derivative losses generally increase the recoverable costs of electric and gas purchases.


		For the Six Months Ended June 30,
		Con Edison		CECONY
(Millions of Dollars)	Financial Statement Location (a)	2026	2025	2026	2025

(b)Unrealized net deferred gains on electric and gas derivatives for the Utilities increased as a result of higher electric and gas commodity prices during the six months ended June 30, 2026. Upon settlement, short-term deferred derivative losses generally increase the recoverable costs of electric and gas purchases.

Schedule of Hedged Volume of Derivative Transactions

The following table presents the hedged volume of Con Edison’s and CECONY’s commodity derivative transactions at June 30, 2026:


	Electric Energy (MWh) (a)(b)	Capacity (MW-mos) (a)	Natural Gas (Dt) (a)(b)	Refined Fuels (gallons)
Con Edison	37,754,800	26,100	304,680,000	2,268,000
CECONY	36,017,425	16,125	281,370,000	2,268,000

(a)Volumes are reported net of long and short positions, except natural gas collars where the volumes of long positions are reported.

(b)Excludes electric congestion and gas basis swap contracts which are associated with electric and gas contracts and hedged volumes.

Schedule of Aggregate Fair Value of Companies' Derivative Instruments with Credit-Risk-Related Contingent Features

The following table presents the aggregate fair value of the Companies’ derivative instruments with credit-risk-related contingent features that are in a net liability position, the collateral posted including cash and letters of credit for such positions and the additional cash collateral that would have been required to be posted had the lowest applicable credit rating been reduced one level and to below investment grade at June 30, 2026:


(Millions of Dollars)	Con Edison (a)	CECONY (a)
Aggregate fair value – net liabilities	$17	$14
Collateral posted	2	—
Additional collateral (b) (downgrade one level from current ratings)	—	—
Additional collateral (b)(c) (downgrade to below investment grade from current ratings)	56	49

(a)Non-derivative transactions for the purchase and sale of electricity and gas and qualifying derivative instruments, that have been designated as normal purchases or normal sales, are excluded from the table. These transactions primarily include purchases of electricity from independent system operators. In the event the Utilities are no longer extended unsecured credit for such purchases, the Companies would be required to post additional cash collateral of $1 million at June 30, 2026. For certain other such non-derivative transactions, the Companies could be required to post collateral under certain circumstances, including in the event counterparties had reasonable grounds for insecurity.

(b)The Companies measure the collateral requirements by taking into consideration the fair value amounts of derivative instruments that contain credit-risk-related contingent features that are in a net liability position plus amounts owed to counterparties for settled transactions and amounts required by counterparties for minimum financial security. The fair value amounts represent unrealized losses, net of any unrealized gains where the Companies have a legally enforceable right to offset.

(c)Derivative instruments that are net assets have been excluded from the table. At June 30, 2026, if Con Edison and CECONY had been downgraded to below investment grade, they would have been required to post additional cash collateral for such derivative instruments of $57 million and $52 million, respectively.

- Definition

Tabular disclosure of credit derivatives which includes information by sellers of credit derivatives, about each credit derivative, or each group of similar credit derivatives, including (a) the nature of the credit derivative - its term, how it arose, the events or circumstances that would require the seller to perform under the credit derivative, and the current status of the payment/performance risk of the credit derivative; (b) the maximum potential amount of future payments (undiscounted) the seller could be required to make under the credit derivative; (c) the current fair value of the credit derivative; and (d) the nature of any recourse provisions under the credit derivative, and any assets held either as collateral or by third parties. A credit derivative is a derivative instrument (1) in which one or more of its underlyings are related to the credit risk of a specified entity (or a group of entities) or an index based on the credit risk of a group of entities and (2) that exposes the seller to potential loss from credit-risk-related events specified in the contract. Examples of credit derivatives within the scope of this paragraph include, but are not limited to, credit default swaps, credit spread options, and credit index products; also includes a hybrid instrument that has an embedded credit derivative (for example, but not limited to, a credit-linked note).

Fair Value Disclosures [Abstract]

Fair Value Measurements

The accounting rules for fair value measurements and disclosures define fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date in a principal or most advantageous market. Fair value is a market-based measurement that is determined based on inputs, that refer broadly to assumptions that market participants use in pricing assets or liabilities. These inputs can be readily observable, market corroborated, or generally unobservable firm inputs. The Companies often make certain assumptions that market participants would use in pricing the asset or liability, including assumptions about risk, and the risks inherent in the inputs to valuation techniques. The Companies use valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs.

The accounting rules for fair value measurements and disclosures established a fair value hierarchy, that prioritizes the inputs to valuation techniques used to measure fair value in three broad levels. The rules require that assets and liabilities be classified in their entirety based on the level of input that is significant to the fair value measurement. Assessing the significance of a particular input may require judgment considering factors specific to the asset or liability and may affect the valuation of the asset or liability and their placement within the fair value hierarchy. The Companies classify fair value balances based on the fair value hierarchy defined by the accounting rules for fair value measurements and disclosures as follows:

•Level 1 – Consists of assets or liabilities whose value is based on unadjusted quoted prices in active markets at the measurement date. An active market is one in which transactions for assets or liabilities occur with sufficient frequency and volume to provide pricing information on an ongoing basis. This category includes contracts traded on active exchange markets valued using unadjusted prices quoted directly from the exchange.

•Level 2 – Consists of assets or liabilities valued using industry standard models and based on prices, other than quoted prices within Level 1, that are either directly or indirectly observable as of the measurement date. The industry standard models consider observable assumptions including time value, volatility factors and current market and contractual prices for the underlying commodities, in addition to other economic measures. This category includes contracts traded on active exchanges or in over-the-counter markets priced with industry standard models.

•Level 3 – Consists of assets or liabilities whose fair value is estimated based on internally developed models or methodologies using inputs that are generally less readily observable and supported by little, if any, market activity at the measurement date. Unobservable inputs are developed based on the best available information and subject to cost benefit constraints. This category includes contracts priced using models that are internally developed and contracts placed in illiquid markets. It also includes contracts that expire after the period of time for which quoted prices are available and internal models are used to determine a significant portion of the value.

Assets and liabilities measured at fair value on a recurring basis as of June 30, 2026 and December 31, 2025 are summarized below.

The employees in the Companies’ risk management group develop and maintain the Companies’ valuation policies and procedures for, and verify pricing and fair value valuation of, commodity derivatives. Under the Companies’ policies and procedures, multiple independent sources of information are obtained for forward price curves used to value commodity derivatives. Fair value and changes in fair value of commodity derivatives are reported monthly to the Companies’ risk committees, comprised of officers and employees of the Companies that oversee energy hedging at the Utilities. The risk management group reports to the Companies’ Vice President and Treasurer.

Realized gains and losses on the Utilities' Level 3 commodity derivative assets and liabilities are reported as part of purchased power, gas and fuel costs. The Utilities generally recover these costs in accordance with rate provisions approved by the applicable state public utilities regulators. See Note A. Unrealized gains and losses for commodity derivatives are generally deferred on the Companies' consolidated balance sheets in accordance with the accounting rules for regulated operations.

Summary of Significant Accounting Policies and Other Matters (Policies)	6 Months Ended
	Jun. 30, 2026
Accounting Policies [Abstract]
Accounting Policies	Accounting Policies The accounting policies of Con Edison and its subsidiaries conform to generally accepted accounting principles in the United States of America (GAAP). For the Utilities, these accounting principles include the accounting rules for regulated operations and the accounting requirements of the Federal Energy Regulatory Commission (FERC) and the state regulators having jurisdiction.
Investments	Investments Con Edison's investments consist primarily of the fair value of the Utilities' supplemental retirement income plan and deferred income plan assets. In April 2026, CECONY and Con Edison Transmission entered into an agreement to sell their interests in Honeoye Storage Corporation (Honeoye) for $5 million in aggregate, of which approximately $1.5 million was attributed to CECONY, before certain closing adjustments and expenses. The closing is expected to occur following approval by the NYSPSC. Investment in Mountain Valley Pipeline, LLC (MVP) During the first quarter of 2026, Con Edison Transmission completed the sale of its approximately 6.6 percent equity interest in MVP to the two founding members of MVP for total aggregate consideration of $357.5 million, before certain closing adjustments and expenses. Prior to the sale, Con Edison recorded its pro rata share of earnings from its equity interest in MVP, adjusted for accretion of the basis difference and income taxes, on its consolidated income statement of $7 million ($5 million after-tax) and $15 million ($11 million after-tax) for the six months ended June 30, 2026 and 2025, respectively. See Note Q for further information.
Reclassification	Reclassification Certain prior period amounts have been reclassified to conform with the current period presentation.
Earnings Per Share	Earnings Per Share Con Edison presents basic and diluted earnings per share (EPS) on the face of its consolidated income statement. Basic EPS is calculated by dividing earnings available to common shareholders (“Net income for common stock” on Con Edison’s consolidated income statement) by the weighted average number of Con Edison common shares outstanding during the period. In the calculation of diluted EPS, weighted average shares outstanding are increased for additional shares that would be outstanding if potentially dilutive securities were converted to common stock. Potentially dilutive securities for Con Edison consist of restricted stock units and deferred stock units for which the average market price of the common shares for the period was greater than the estimated vesting price, and its common shares that are subject to forward sale agreements (see Note C). Before the issuance of common shares upon settlement of the forward sale agreements, the shares will be reflected in the company’s diluted earnings per share calculations using the treasury stock method. Under this method, the number of common shares used in calculating diluted earnings per share is deemed to be increased by the excess, if any, of the number of shares that would be issued upon physical settlement of the forward sale agreements over the number of shares that could be purchased by the company in the market (based on the average market price during the period) using the proceeds due upon physical settlement (based on the adjusted forward sale price at the end of the reporting period).
Variable Interest Entities	Variable Interest Entities The accounting rules for consolidation address the consolidation of a variable interest entity (VIE) by a business enterprise that is the primary beneficiary. A VIE is an entity that does not have a sufficient equity investment at risk to permit it to finance its activities without additional subordinated financial support, or whose equity investors lack the characteristics of a controlling financial interest. The primary beneficiary is the business enterprise that has the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and either absorbs a significant amount of the VIE’s losses or has the right to receive benefits that could be significant to the VIE. The Companies enter into arrangements including leases, partnerships and electricity purchase agreements, with various entities. As a result of these arrangements, the Companies retain or may retain a variable interest in these entities. CECONY has an ongoing long-term electricity purchase agreement with Brooklyn Navy Yard Cogeneration Partners, LP, a potential VIE. In 2025, a request was made of this counterparty for information necessary to determine whether the entity was a VIE and whether CECONY is the primary beneficiary; however, the information was not made available. The payments for this contract constitute CECONY’s maximum exposure to loss with respect to the potential VIE.
Fair Value Measurements	Fair Value Measurements The accounting rules for fair value measurements and disclosures define fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date in a principal or most advantageous market. Fair value is a market-based measurement that is determined based on inputs, that refer broadly to assumptions that market participants use in pricing assets or liabilities. These inputs can be readily observable, market corroborated, or generally unobservable firm inputs. The Companies often make certain assumptions that market participants would use in pricing the asset or liability, including assumptions about risk, and the risks inherent in the inputs to valuation techniques. The Companies use valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. The accounting rules for fair value measurements and disclosures established a fair value hierarchy, that prioritizes the inputs to valuation techniques used to measure fair value in three broad levels. The rules require that assets and liabilities be classified in their entirety based on the level of input that is significant to the fair value measurement. Assessing the significance of a particular input may require judgment considering factors specific to the asset or liability and may affect the valuation of the asset or liability and their placement within the fair value hierarchy. The Companies classify fair value balances based on the fair value hierarchy defined by the accounting rules for fair value measurements and disclosures as follows: •Level 1 – Consists of assets or liabilities whose value is based on unadjusted quoted prices in active markets at the measurement date. An active market is one in which transactions for assets or liabilities occur with sufficient frequency and volume to provide pricing information on an ongoing basis. This category includes contracts traded on active exchange markets valued using unadjusted prices quoted directly from the exchange. •Level 2 – Consists of assets or liabilities valued using industry standard models and based on prices, other than quoted prices within Level 1, that are either directly or indirectly observable as of the measurement date. The industry standard models consider observable assumptions including time value, volatility factors and current market and contractual prices for the underlying commodities, in addition to other economic measures. This category includes contracts traded on active exchanges or in over-the-counter markets priced with industry standard models. •Level 3 – Consists of assets or liabilities whose fair value is estimated based on internally developed models or methodologies using inputs that are generally less readily observable and supported by little, if any, market activity at the measurement date. Unobservable inputs are developed based on the best available information and subject to cost benefit constraints. This category includes contracts priced using models that are internally developed and contracts placed in illiquid markets. It also includes contracts that expire after the period of time for which quoted prices are available and internal models are used to determine a significant portion of the value.
New Financial Accounting Standards	New Financial Accounting Standards In May 2026, the Financial Accounting Standards Board (FASB) issued guidance on accounting for Environmental Credits and Environmental Credit Obligations (Topic 818) through ASU 2026-02. The guidance addresses accounting for and disclosure of environmental credits and environmental credit obligations. It provides recognition, measurement, presentation, and disclosure requirements for all entities that generate, purchase, or receive environmental credits or have a regulatory compliance obligation that may be settled with environmental credits. The amendments in ASU 2026-02 are effective for fiscal years beginning after December 15, 2027, and interim reporting periods within those fiscal years, with early adoption permitted. The Companies are evaluating the potential impact of this new standard on their financial position, results of operations and liquidity.

Debt Disclosure [Abstract]
Short-Term Borrowing	Short-Term Borrowing In March 2026, Con Edison and the Utilities entered into a Credit Agreement (the Credit Agreement) that replaced a March 2023 Credit Agreement and a March 2025 CECONY 364-Day Revolving Credit Agreement under which banks are committed to provide loans and letters of credit, on a revolving credit basis. The Credit Agreement expires in March 2031, unless extended for up to two additional one-year terms. There is a maximum of $3,500 million of credit available. The full amount is available to CECONY and $800 million (subject to increase up to $1,000 million) is available to Con Edison, including up to $900 million of letters of credit. The Companies intend to use the Credit Agreement to support their commercial paper programs. Loans and letters of credit issued under the Credit Agreement may also be used for other general corporate purposes. Any borrowings under the Credit Agreement would generally be at variable interest rates. Interest and fees for loans and letters of credit under the Credit Agreement generally reflect the respective credit ratings of the Companies. The banks’ commitments under the Credit Agreement are subject to certain conditions, including that there be no event of default or event which with notice or the lapse of time would become an event of default with respect to any company. The commitments are not subject to maintenance of credit rating levels or the absence of a material adverse change. Upon a change of control of, or upon an event of default by one of the companies, the banks may terminate their commitments with respect to that company, declare any amounts owed by that company immediately due and payable and require that company to provide cash collateral relating to the letters of credit issued for it under the Credit Agreement. Events of default for a company include, among other things, that company's failure to pay any principal of any loan or any draw under any letter of credit issued pursuant to the Credit Agreement when due; that company's failure to pay any interest or fees pursuant to the Credit Agreement within five days; that company's failure to meet certain covenants, including covenants that the company's ratio of consolidated debt to consolidated total capital not at any time exceed 0.65 to 1; the company creating, assuming or suffering a lien or other encumbrance on its assets exceeding 10 percent of that company's consolidated net tangible assets; that company failing to make one or more payments in respect of material financial obligations (in excess of $150 million in aggregate); the occurrence of an event or condition which results in the acceleration of the maturity of any material debt (in excess of $150 million in aggregate); and other customary events of default. At June 30, 2026 no loans or letters of credit were outstanding under the Credit Agreement, the March 2023 Credit Agreement or the March 2025 CECONY 364-Day Revolving Credit Agreement. The Companies were in compliance with their significant debt covenants at June 30, 2026. In March 2026, CECONY repaid in full prior to maturity $500 million pursuant to a 364-Day Senior Unsecured Term Loan Agreement entered into by the company in November 2025. At June 30, 2026, Con Edison had $721 million of commercial paper outstanding, of which $480 million of commercial paper was outstanding under CECONY’s program. The weighted average interest rate at June 30, 2026 was 3.9 percent for both Con Edison and CECONY. At December 31, 2025, Con Edison had $1,575 million of commercial paper outstanding, of which $1,240 million was outstanding under CECONY’s program. The weighted average interest rate at December 31, 2025 was 3.9 percent for both Con Edison and CECONY.

Debt Disclosure [Abstract]

Capitalization

In May 2026, Con Edison entered into an equity distribution agreement (EDA), pursuant to which Con Edison may sell, from time to time, up to an aggregate sales price of $2.0 billion of its common stock through an at-the-market

(ATM) equity offering program (ATM Program), including an equity forward sales component. Con Edison subsequently entered into forward sale agreements under the ATM Program and as of June 30, 2026, the ATM Program had approximately $1.8 billion of common stock available for issuance.

The following table shows ATM equity issuances pursuant to forward sale agreements executed in May 2026.


Tranche	Shares Priced	Initial Forward Price
1	1,074,178 (a)	$105.7586
2	889,415	$104.6730

(a) In June 2026, Con Edison physically settled a portion of Tranche 1, as described below.

The forward sale agreements require Con Edison to either physically settle the transactions by issuing shares in exchange for net proceeds at the then-applicable forward sale price specified by the forward sale agreements or net settle in whole or in part through the delivery or receipt of cash or shares. The settlement alternatives are at Con Edison’s election and Con Edison expects to fully physically settle each forward sale agreement. Except for amounts recorded upon settlement of forward sale agreements that have settled, no amounts have been or will be recorded in Con Edison’s Consolidated Financial Statements with respect to the offerings under the ATM Program prior to settlement of the applicable forward sale agreements. The initial forward sale prices will be subject to adjustment on a daily basis based on a floating interest rate factor and will be subject to decrease on each of certain dates by amounts related to expected dividends on Con Edison's common stock during the term of the relevant forward sale agreements. Until settlement of the equity forwards, earnings per share dilution resulting from the forward sale agreements will be determined under the treasury stock method. The forward sale agreements have been classified as equity transactions.

In June 2026, Con Edison physically settled a portion of outstanding equity forwards under the ATM Program by delivering 1,018,307 shares of its common stock in exchange for total net cash proceeds of approximately $108 million.

In March 2026, Con Edison issued 7,000,000 shares of its common stock for approximately $776 million upon physical settlement of a forward sale agreement entered into by the company in February 2026.

In June 2026, CECONY issued $450 million aggregate principal amount of 5.15 percent debentures, due 2036 and $850 million aggregate principal amount of 5.875 percent debentures, due 2056.

The carrying amounts and fair values of long-term debt at June 30, 2026 and December 31, 2025 were:


(Millions of Dollars)	2026		2025
Long-Term Debt (including current portion) (a)	Carrying Amount	Fair Value	Carrying Amount	Fair Value
Con Edison	$27,093	$24,595	$25,801	$23,633
CECONY	$25,601	$23,273	$24,310	$22,291

The fair values of the Companies' long-term debt have been estimated primarily using available market information and at June 30, 2026 are classified as Level 2 liabilities. See Note O.

Accounting Policies [Abstract]
General	General These combined notes accompany and form an integral part of the separate interim consolidated financial statements of each of the two separate registrants: Consolidated Edison, Inc. and its subsidiaries (Con Edison) and Consolidated Edison Company of New York, Inc. and its subsidiaries (CECONY). CECONY is a subsidiary of Con Edison and as such its financial condition and results of operations and cash flows, that are presented separately in the CECONY consolidated financial statements, are also consolidated, along with those of Orange and Rockland Utilities, Inc. (O&R) and Con Edison Transmission, Inc. (together with its subsidiaries, Con Edison Transmission) in Con Edison’s consolidated financial statements. The term “Utilities” is used in these notes to refer to CECONY and O&R. As used in these notes, the term “Companies” refers to Con Edison and CECONY and, except as otherwise noted, the information in these combined notes relates to each of the Companies. However, CECONY makes no representation as to information contained in these combined notes relating to Con Edison or the subsidiaries of Con Edison other than itself. The separate interim consolidated financial statements of each of the Companies are unaudited but, in the opinion of their respective managements, reflect all adjustments (which include only normally recurring adjustments) necessary for a fair statement of the results for the interim periods presented. The Companies’ separate interim consolidated financial statements should be read together with their separate audited financial statements (including the combined notes thereto) included in Item 8 of their combined Annual Report on Form 10-K for the year ended December 31, 2025, and their separate unaudited financial statements (including the combined notes thereto) included in Part 1, Item 1 of their combined Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2026. Con Edison has two regulated utility subsidiaries: CECONY and O&R. CECONY provides electric service and gas service in New York City and Westchester County. The company also provides steam service in parts of Manhattan. O&R, along with its regulated utility subsidiary, provides electric service in southeastern New York and northern New Jersey and gas service in southeastern New York. Con Edison Transmission develops and invests in electric transmission projects and owns interests in electric assets. See “Investments” in Note A.

Accounting Changes and Error Corrections (Policies)	6 Months Ended
Accounting Changes and Error Corrections (Policies)	Jun. 30, 2026
Accounting Changes and Error Corrections [Abstract]
New Financial Accounting Standards	New Financial Accounting Standards In May 2026, the Financial Accounting Standards Board (FASB) issued guidance on accounting for Environmental Credits and Environmental Credit Obligations (Topic 818) through ASU 2026-02. The guidance addresses accounting for and disclosure of environmental credits and environmental credit obligations. It provides recognition, measurement, presentation, and disclosure requirements for all entities that generate, purchase, or receive environmental credits or have a regulatory compliance obligation that may be settled with environmental credits. The amendments in ASU 2026-02 are effective for fiscal years beginning after December 15, 2027, and interim reporting periods within those fiscal years, with early adoption permitted. The Companies are evaluating the potential impact of this new standard on their financial position, results of operations and liquidity.

Environmental Remediation Obligations [Abstract]

Environmental Matters

Superfund Sites

Hazardous substances, such as asbestos, polychlorinated biphenyls (PCBs) and coal tar, have been used or generated in the course of operations of the Utilities and their predecessors and are present at sites and in facilities and equipment they currently or previously owned, including sites at which gas was manufactured or stored.

The Federal Comprehensive Environmental Response, Compensation and Liability Act of 1980 and similar state statutes (Superfund) impose joint and several liability, regardless of fault, upon generators of hazardous substances for investigation and remediation costs (which include costs of demolition, removal, disposal, storage, replacement, containment and monitoring) and natural resource damages. Liability under these laws can be material and may be imposed for contamination from past acts, even though such past acts may have been lawful at the time they occurred. The sites at which the Utilities have been asserted to have liability under these laws, including their manufactured gas plant sites and any neighboring areas to which contamination may have migrated, are referred to herein as “Superfund Sites.”

For Superfund Sites where there are other potentially responsible parties and the Utilities are not managing the site investigation and remediation, the accrued liability represents an estimate of the amount the Utilities will need to pay to investigate and, where determinable, discharge their related obligations. For Superfund Sites (including the manufactured gas plant sites) for which one of the Utilities is managing the investigation and remediation, the accrued liability represents an estimate of the company's share of the undiscounted cost to investigate the sites and, for sites that have been investigated in whole or in part, the cost to remediate the sites, if remediation is necessary and if a reasonable estimate of such cost can be made. Remediation costs are estimated in light of the information available, applicable remediation standards and experience with similar sites.

The accrued liabilities and regulatory assets related to Superfund Sites at June 30, 2026 and December 31, 2025 were as follows:


	Con Edison		CECONY
(Millions of Dollars)	2026	2025	2026	2025
Accrued Liabilities:
Manufactured gas plant sites	$976	$980	$879	$882
Other Superfund Sites	102	99	101	98
Total	$1,078	$1,079	$980	$980
Regulatory assets	$1,079	$1,079	$988	$987

Most of the accrued Superfund Site liability relates to sites that have been investigated, in whole or in part. However, for some of the sites, the extent and associated cost of the required remediation has not yet been determined. As investigations progress and information pertaining to the required remediation becomes available, the Utilities expect that additional liability may be accrued, the amount of which is not presently determinable but may be material. The Utilities defer prudently incurred investigation and remediation costs as regulatory assets (for subsequent recovery through rates).

Environmental remediation costs incurred related to Superfund Sites for the three and six months ended June 30, 2026 and 2025 were as follows:


	For the Three Months Ended June 30,
	Con Edison		CECONY
(Millions of Dollars)	2026	2025	2026	2025
Remediation costs incurred	$3	$5	$3	$4


	For the Six Months Ended June 30,
	Con Edison		CECONY
(Millions of Dollars)	2026	2025	2026	2025
Remediation costs incurred	$6	$14	$6	$13

Insurance and other third-party recoveries received by Con Edison or CECONY were immaterial for the three and six months ended June 30, 2026 and 2025.

Con Edison and CECONY estimated that for their manufactured gas plant sites (including CECONY’s Astoria site), the aggregate undiscounted potential liability for the investigation and remediation of coal tar and/or other environmental contaminants could range up to $3,540 million and $3,380 million, respectively. These estimates were based on the assumption that there is contamination at all sites, including those that have not yet been fully investigated and additional assumptions about the extent of the contamination and the type and extent of the remediation that may be required. Actual experience may be materially different.

Asbestos Proceedings

Suits have been brought in New York State and federal courts against the Utilities and many other defendants, wherein a large number of plaintiffs sought significant compensatory and punitive damages for deaths and injuries allegedly caused by or relating to exposure to asbestos and asbestos-containing materials at various premises of the Utilities. The suits that have been resolved, that are many, have been resolved without any payment by the Utilities, or for amounts that were not, in the aggregate, material to them. The amounts specified in all the remaining thousands of suits total billions of dollars; however, the Utilities believe that these amounts are greatly exaggerated, based on the disposition of previous claims. At June 30, 2026 and December 31, 2025, Con Edison and CECONY have accrued their estimated aggregate undiscounted potential liabilities for these suits and additional suits that may be brought through 2040 as shown in the following table. These estimates were based upon a combination of modeling, historical data analysis and risk factor assessment. Courts have modified, and may continue to modify, standards for determining liability and the reasonableness of awards in asbestos suits. As a result, the Companies currently believe that there is a reasonable possibility of an exposure to loss in excess of the liability accrued for the suits. The Companies are unable to estimate the amount or range of such loss. In addition, certain current and former employees have claimed or are claiming workers’ compensation benefits based on alleged disability from exposure to asbestos. CECONY is permitted to defer as regulatory assets (for subsequent recovery through rates) costs incurred for its asbestos lawsuits and workers’ compensation claims.


	Con Edison		CECONY
(Millions of Dollars)	2026	2025	2026	2025
Accrued liability – asbestos suits	$11	$11	$10	$10
Regulatory assets – asbestos suits	11	11	10	10
Accrued liability – workers’ compensation	$50	$51	$48	$49
Regulatory liabilities – workers’ compensation	23	21	23	21

Related Party Transactions

6 Months Ended

Jun. 30, 2026

Related Party Transactions

The NYSPSC generally requires that the Utilities and Con Edison’s other subsidiaries be operated as separate entities. The Utilities may provide administrative and other services to Con Edison and its other subsidiaries only pursuant to cost allocation policies and procedures approved by the NYSPSC. Transfers of certain assets between the Utilities and Con Edison or its other subsidiaries may be made only as approved by the NYSPSC. The debt of the Utilities is to be raised directly by the Utilities and not derived from Con Edison. Without the prior permission of the NYSPSC, the Utilities may not make loans to, guarantee the obligations of, or pledge assets as security for the indebtedness of Con Edison or its other subsidiaries. The NYSPSC limits the dividends that the Utilities may pay Con Edison. As a result, substantially all of the net assets of CECONY and O&R ($23,567 million and $1,463 million, respectively), at June 30, 2026, are considered restricted net assets. The NYSPSC may impose additional measures to separate, or “ring fence,” the Utilities from Con Edison and its other subsidiaries.

The costs of administrative and other services provided by CECONY to, and received by it from, Con Edison and its other subsidiaries for the three and six months ended June 30, 2026 and 2025 were as follows:


	For the Three Months Ended June 30,
	CECONY
(Millions of Dollars)	2026	2025
Cost of services provided	$43	$37
Cost of services received	$22	$22


	For the Six Months Ended June 30,
	CECONY
(Millions of Dollars)	2026	2025
Cost of services provided	$81	$77
Cost of services received	$43	$42

In addition, CECONY and O&R have joint gas supply arrangements pursuant to which CECONY sold to, or acted as agent to purchase for, O&R, $12 million and $19 million of natural gas for the three months ended June 30, 2026 and 2025, respectively, and $73 million and $63 million of natural gas for the six months ended June 30, 2026 and 2025, respectively. These amounts are net of the effect of related hedging transactions.

At June 30, 2026 and December 31, 2025, CECONY's net receivable from Con Edison for income taxes was $232 million and $24 million, respectively.

The Utilities perform work and incur expenses on behalf of New York Transco, a company in which Con Edison Transmission owns an interest. The Utilities bill New York Transco for such work and expenses in accordance with established policies. For the three months ended June 30, 2026 and 2025, the amounts billed by the Utilities to New York Transco were immaterial. For the six months ended June 30, 2026 and 2025, the amounts billed by the Utilities to New York Transco were immaterial.

The FERC has authorized CECONY to lend funds to O&R for a period of not more than 12 months, in an amount not to exceed $250 million, at prevailing market rates. At June 30, 2026 and December 31, 2025, there were no outstanding loans to O&R.

Derivative Instruments and Hedging Activities

6 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments and Hedging Activities

Con Edison’s subsidiaries hedge market price fluctuations associated with physical purchases and sales of electricity, natural gas, steam and, to a lesser extent, refined fuels by using derivative instruments including futures, forwards, basis swaps, options, transmission congestion contracts and financial transmission rights contracts. These are economic hedges, for which the Utilities do not elect hedge accounting. The Companies use economic hedges to manage commodity price risk in accordance with provisions set by state regulators. The volume of hedging activity at the Utilities depends upon the forecasted volume of physical commodity supply to meet customer needs, and program costs or benefits are recovered from or credited to full-service customers, respectively. Derivatives are recognized on the consolidated balance sheet at fair value (see Note O), unless an exception is available under the accounting rules for derivatives and hedging. Qualifying derivative contracts that have been designated as normal purchases or normal sales contracts are not reported at fair value under the accounting rules.

The fair values of the Companies’ derivatives, including the offsetting of assets and liabilities on the consolidated balance sheets at June 30, 2026 and December 31, 2025 were:

The Utilities generally recover their prudently incurred fuel, purchased power and gas costs, including hedging gains and losses, in accordance with rate provisions approved by the applicable state utility regulators. In accordance with the accounting rules for regulated operations, the Utilities record a regulatory asset or regulatory liability to defer recognition of unrealized gains and losses on their electric and gas derivatives. As gains and losses are realized in future periods, they will be recognized as purchased power, gas and fuel costs in the Companies’ consolidated income statements.

The following tables present the realized and unrealized gains or losses on derivatives that have been deferred or recognized in earnings for the three and six months ended June 30, 2026 and 2025:


		For the Three Months Ended June 30,
		Con Edison		CECONY
(Millions of Dollars)	Financial Statement Location (a)	2026	2025	2026	2025
Pre-tax gains (losses) deferred in accordance with accounting rules for regulated operations:

Total deferred gains (losses)		$153	$19	$146	$19
Current	Regulatory assets	$10	$(5)	$11	$(5)
Current	Recoverable energy costs	188	54	171	51

Total deferred gains (losses)		$191	$50	$174	$46
Net deferred gains (losses) (b)		$344	$69	$320	$65

The following table presents the hedged volume of Con Edison’s and CECONY’s commodity derivative transactions at June 30, 2026:


	Electric Energy (MWh) (a)(b)	Capacity (MW-mos) (a)	Natural Gas (Dt) (a)(b)	Refined Fuels (gallons)
Con Edison	37,754,800	26,100	304,680,000	2,268,000
CECONY	36,017,425	16,125	281,370,000	2,268,000

(a)Volumes are reported net of long and short positions, except natural gas collars where the volumes of long positions are reported.

(b)Excludes electric congestion and gas basis swap contracts which are associated with electric and gas contracts and hedged volumes.

The Companies are exposed to credit risk related to transactions entered into primarily for the various energy supply and hedging activities by the Utilities. Credit risk relates to the loss that may result from a counterparty’s nonperformance. The Companies use credit policies to manage this risk, including an established credit approval process, monitoring of counterparty limits, netting provisions within agreements, collateral or prepayment arrangements, credit insurance and credit default swaps. The Companies measure credit risk exposure as the replacement cost for open energy commodity and derivative positions plus amounts owed from counterparties for settled transactions. The replacement cost of open positions represents unrealized gains, net of any unrealized losses where the Companies have a legally enforceable right to offset.

At June 30, 2026, Con Edison and CECONY had $96 million and $91 million of credit exposure, respectively, in connection with open energy supply net receivables and hedging activities, net of collateral. Con Edison’s net credit exposure consisted of $84 million with investment-grade counterparties, $11 million with commodity exchange brokers, and $1 million with non-investment grade/non-rated counterparties. CECONY’s net credit exposure consisted of $80 million with investment-grade counterparties, $10 million with commodity exchange brokers, and $1 million with non-investment grade/non-rated counterparties.

The collateral requirements associated with, and settlement of, derivative transactions are included in net cash flows from operating activities in the Companies’ consolidated statements of cash flows. Most derivative instrument contracts contain provisions that may require a party to provide collateral on its derivative instruments that are in a net liability position. The amount of collateral to be provided will depend on the fair value of the derivative instruments and the party’s credit ratings.


(Millions of Dollars)	Con Edison (a)	CECONY (a)
Aggregate fair value – net liabilities	$17	$14
Collateral posted	2	—
Additional collateral (b) (downgrade one level from current ratings)	—	—
Additional collateral (b)(c) (downgrade to below investment grade from current ratings)	56	49

- Definition

The entire disclosure for derivative instruments and hedging activities including, but not limited to, risk management strategies, non-hedging derivative instruments, assets, liabilities, revenue and expenses, and methodologies and assumptions used in determining the amounts.

Discontinued Operations and Disposal Groups [Abstract]
Dispositions	Dispositions Con Edison's sale of all of the stock of the Clean Energy Businesses in March 2023 included all assets, operations and projects of the Clean Energy Businesses with the exception of one deferred project, Broken Bow II, a 75 MW nameplate capacity wind power project located in Nebraska, a tax equity interest in the Crane solar project and a tax equity interest in two renewable electric projects located in Virginia (Virginia Tax Equity Interest). In January 2025, Con Edison completed the sale and transfer of Broken Bow II to RWE and the corresponding value of $54 million (net of assumed debt and other final adjustments) was paid to Con Edison. RWE Renewables Americas, LLC operated the facility on behalf of Con Edison until the sale and transfer to RWE pursuant to certain service agreements, for which the fees were not material. In October 2025, Con Edison sold its tax equity interest in the Crane solar project to another member after holding it for a five-year period. Con Edison continues to retain the Virginia Tax Equity Interest, which produced renewable energy tax credits that can be used to reduce Con Edison’s federal income tax. These tax credits are subject to recapture, in whole or in part, if the assets are sold within a five-year period beginning on the date on which the assets are placed in service. Con Edison will continue to employ HLBV accounting for the Virginia Tax Equity Interest. The carrying value of the Virginia Tax Equity Interest was $5 million at June 30, 2026 and December 31, 2025. During the first quarter of 2026, Con Edison Transmission completed the sale of its approximately 6.6 percent equity interest in MVP to the two founding members of MVP for total aggregate consideration of $357.5 million, before certain closing adjustments and expenses. Con Edison's gain on the sale of the MVP interest was $189 million ($134 million, after tax) for the six months ended June 30, 2026. In April 2026, CECONY and Con Edison Transmission entered into an agreement to sell their interests in Honeoye for $5 million in aggregate, of which approximately $1.5 million was attributed to CECONY, before certain closing adjustments and expenses. The closing is expected to occur following approval by the NYSPSC.

Current Expected Credit Losses

6 Months Ended

Jun. 30, 2026

Credit Loss [Abstract]

Current Expected Credit Losses

Allowance for Uncollectible Accounts

The Utilities’ “Account receivable – customers” balance consists of utility bills due (bills are generally due the month following billing) from customers who have energy delivered, generated, or services provided by the Utilities. The balance also reflects the Utilities’ purchase of receivables from energy service companies to support the retail choice programs.

The “Other receivables” balance generally reflects costs billed by the Utilities for goods and services provided to external parties, such as accommodation work for private parties and certain governmental entities, real estate rental and pole attachments.

The Companies develop expected loss estimates using past events data and consider current conditions and future reasonable and supportable forecasts. Changes to the Utilities’ reserve balances that result in write-offs of customer accounts receivable balances above existing rate allowances are not reflected in rates during the term of the current rate plans. For the Utilities’ allowance for uncollectible accounts for customer accounts receivable, which includes accrued unbilled revenue, past events considered include write-offs relative to customer accounts receivable;

current conditions include macro-and micro-economic conditions related to trends in the local economy, reconnection rates and current and aged customer accounts receivable balances, including final balances, among other factors; and forecasts about the future include assumptions related to the level of write-offs and recoveries. The change to the allowance for customer uncollectible accounts for Con Edison and CECONY was $(10) million for the three months ended June 30, 2026 and $(49) million and $(50) million, respectively, for the six months ended June 30, 2026. The change to the allowance for customer uncollectible accounts for Con Edison and CECONY was $(1) million and no change, respectively, for the three months ended June 30, 2025 and $(5) million and no change, respectively, for the six months ended June 30, 2025. Generally, the Utilities write off customer accounts receivable as uncollectible 90 days after the account is disconnected for non-payment, or the account is closed during the collection process.

Other receivables allowance for uncollectible accounts is calculated based on a historical average of collections relative to total other receivables, including current receivables. Current macro- and micro-economic conditions are also considered when calculating the current reserve. Probable outcomes of pending litigation, whether favorable or unfavorable to the Companies, are also included in the consideration.

Customer accounts receivable and the associated allowance for uncollectible accounts are included in the line “Accounts receivable – customers” on the Companies’ consolidated balance sheets. Other receivables and the associated allowance for uncollectible accounts are included in “Other receivables” on the Companies’ consolidated balance sheets.

The table below presents a rollforward by major portfolio segment type for the three and six months ended June 30, 2026 and 2025:

Material Contingencies	6 Months Ended
Material Contingencies	Jun. 30, 2026
Commitments and Contingencies Disclosure [Abstract]
Material Contingencies	Material Contingencies Manhattan Explosion and Fire On March 12, 2014, two multi-use five-story tall buildings located on Park Avenue between 116th and 117th Streets in Manhattan were destroyed by an explosion and fire. CECONY had delivered gas to the buildings through service lines from a distribution main located below ground on Park Avenue. Eight people died and more than 50 people were injured. Additional buildings were also damaged. The National Transportation Safety Board (NTSB) investigated. The parties to the investigation included CECONY, the City of New York, the Pipeline and Hazardous Materials Safety Administration and the NYSPSC. In June 2015, the NTSB issued a final report concerning the incident, its probable cause and safety recommendations. The NTSB determined that the probable cause of the incident was (1) the failure of a defective fusion joint at a service tee (which joined a plastic service line to a plastic distribution main) installed by CECONY that allowed gas to leak from the distribution main and migrate into a building where it ignited and (2) a breach in a city sewer line that allowed groundwater and soil to flow into the sewer, resulting in a loss of support for the distribution main, that caused it to sag and overstressed the defective fusion joint. The NTSB also made safety recommendations, including recommendations to CECONY that addressed its procedures for the preparation and examination of plastic fusions, training of its staff on conditions for notifications to the city’s Fire Department and extension of its gas main isolation valve installation program. In February 2017, the NYSPSC approved a settlement agreement with CECONY related to the NYSPSC's investigations of the incident and the practices of qualifying persons to perform plastic fusions. Pursuant to the agreement, CECONY provided $27 million of future benefits to customers (for which it accrued a regulatory liability) and did not recover from customers $126 million of costs for gas emergency response activities that it had previously incurred and expensed. Lawsuits are pending against CECONY seeking generally unspecified damages and, in some cases, punitive damages, for wrongful death, personal injury, property damage and business interruption. CECONY notified its insurers of the incident and believes that the policies in force at the time of the incident will cover CECONY’s costs, in excess of a required retention (the amount of which is not material), to satisfy any liability it may have for damages in connection with the incident. During 2020, CECONY accrued its estimated liability for the suits of $40 million. As of June 30, 2026, the estimated accrued liability is $25 million, with an insurance receivable in the same amount, due to the settlement or dismissal of multiple litigations that arose from the incident. Other Contingencies For additional contingencies, see "Other Regulatory Matters" in Note B, Note G and “Uncertain Tax Positions” in Note J. Guarantees Con Edison has entered into various agreements providing financial or performance assurance primarily to third parties on behalf of their subsidiaries. Maximum amounts guaranteed by Con Edison under these agreements were immaterial and $60 million at June 30, 2026 and December 31, 2025, respectively.
