Item 7: Management’s Discussion and Analysis of Financial Condition and Results of Operations

This combined management’s discussion and analysis of financial condition and results of operations relates to the consolidated financial statements included in this report of two separate registrants: Con Edison and CECONY, and should be read in conjunction with the financial statements and the notes thereto. As used in this report, the term the “Companies” refers to Con Edison and CECONY. CECONY is a subsidiary of Con Edison and, as such, information in this management’s discussion and analysis about CECONY applies to Con Edison.

Information in any item of this report referred to in this discussion and analysis is incorporated by reference herein. The use of terms such as “see” or “refer to” shall be deemed to incorporate by reference into this discussion and analysis the information to which reference is made.

See "Item 7: Management's Discussion and Analysis of Financial Condition and Results of Operations," in Con Edison's and CECONY's combined Annual Report on Form 10-K for the year ended December 31, 2022, filed with the SEC on February 16, 2023, for a discussion of variance drivers for the year ended December 31, 2022, as compared to December 31, 2021.

Corporate Overview

Con Edison’s principal business operations are those of the Utilities and Con Edison Transmission. CECONY is a regulated utility that provides electric service in New York City and New York's Westchester County, gas service in Manhattan, the Bronx, parts of Queens and parts of Westchester, and steam service in Manhattan. O&R is a regulated utility serving customers in a 1,300-square-mile-area in southeastern New York State and northern New Jersey. Con Edison Transmission, through its subsidiaries, invests in electric transmission projects supporting Con Edison's effort to transition to clean, renewable energy and manages, through joint ventures, both electric and gas assets while seeking to develop electric transmission projects that will bring clean, renewable electricity to customers, focusing on New York, New England, the Mid-Atlantic states and the Midwest. On March 1, 2023, Con Edison completed the sale of all of the stock of the Clean Energy Businesses. See Note W and Note X to the financial statements in Item 8.

In addition to the risks and uncertainties described in Item 1A and the Companies’ material contingencies described in Notes B, G and H to the financial statements in Item 8, the Companies’ management considers the following events, trends, and uncertainties to be important to understanding the Companies’ current and future financial condition.

Clean Energy Goals

The success of the Companies’ efforts to meet federal, state and city clean energy policy goals and the impact of energy consumers' efforts to meet such goals on CECONY’s electric, gas and steam businesses and O&R’s electric and gas businesses may impact the Companies’ future financial condition. The Utilities expect electric usage to increase and gas and steam usage to decrease in their service territories as federal, state and local laws and policies are enacted and implemented that aim to reduce the carbon intensity of the energy that is consumed. The Utilities’ and their regulators’ efforts to maintain electric reliability in their service territories as electric usage increases may also impact the Companies’ future financial condition. The long-term future of the Utilities’ gas businesses depends upon the role that natural gas or other gaseous fuels will play in facilitating New York State’s and New York City’s climate goals. In addition, the impact and costs of climate change on the Utilities’ systems and the success of the Utilities’ efforts to maintain system reliability and manage service interruptions resulting from severe weather may impact the Companies’ future financial condition, results of operations and liquidity.

Aged Accounts Receivable Balances

At December 31, 2023, CECONY’s and O&R’s customer accounts receivables balances of $2,683 million and $95 million, respectively, included aged accounts receivables (balances outstanding in excess of 60 days) of $1,225 million and $21 million, respectively. In comparison, CECONY’s and O&R’s customer accounts receivable balances at February 28, 2020 were $1,322 million and $89 million, respectively, including aged accounts receivables of $408 million and $15 million, respectively. Prior to the start of the COVID-19 pandemic, the Utilities’ practice was to write off customer accounts receivables as uncollectible 90 days after the account is disconnected for non-payment or the account is closed during the collection process. Due to the COVID-19 pandemic, New York State enacted laws prohibiting New York utilities, including CECONY and O&R, from disconnecting residential customers and small business customers. The Utilities largely suspended service disconnections, certain collection notices, final bill collection agency activity, new late payment charges and certain other fees from March 2020 through December 2021. CECONY’s electric and gas rate plans include reconciliation of late payment charges (from January 1, 2023 through December 31, 2025) and write-offs of customer accounts receivable balances (from January 1, 2020

50 CON EDISON ANNUAL REPORT 2023

through December 31, 2025) to amounts reflected in rates, with recovery/refund from or to customers via surcharge/sur-credit. CECONY's surcharge recoveries for late payment charges and write-offs of accounts receivable balances will, collectively, be subject to separate annual caps for electric and gas that produce no more than a half percent (0.5 percent) total customer bill impact per commodity (estimated for electric to be $57.3 million, $60.3 million, $62.6 million for 2023, 2024 and 2025, respectively, and for gas to be $14.8 million, $15.9 million and $16.8 million for 2023, 2024 and 2025, respectively). Amounts in excess of the surcharge caps will be deferred as a regulatory asset for recovery in CECONY’s next base rate cases. O&R’s 2022 - 2024 rate plans include reconciliation of late payment charges to amounts reflected in rates for years 2022 through 2024, with full recovery/refund via surcharge/sur-credit once the annual variance equals or exceeds 5 basis points of return on equity and reconciliation of write-offs of customer accounts receivable balances to amounts reflected in rates from January 1, 2020 through December 31, 2024, with full recovery/refund via surcharge/sur-credit once the annual variance equals or exceeds 5 basis points of return on equity. Although these regulatory mechanisms are in place, a continued slower recovery in cash of outstanding customer accounts receivable balances has impacted the Companies’ liquidity and may continue to impact liquidity. See “Liquidity and Capital Resources” and “Capital Requirements and Resources,” below and "Regulatory Matters – Rate Plans" and “COVID-19 Regulatory Matters” in Note B to the financial statements in Item 8.

Con Edison Transmission

Con Edison Transmission, through its New York Transco partnership and jointly with the New York Power Authority, is developing the Propel NY Energy transmission project that will deliver offshore wind energy from Long Island to New York City, Westchester County and the rest of New York State's high voltage power grid. Con Edison Transmission expects to continue to participate in competitive solicitations to develop additional electric projects. The success of Con Edison Transmission’s efforts in these competitive solicitations and to grow its electric transmission portfolio may impact Con Edison’s future capital requirements. See "Con Edison Transmission" in Item 1.

See Note W and Note X to the financial statements in Item 8.

(c)On March 1, 2023, Con Edison completed the sale of all of the stock of the Clean Energy Businesses. See Note W and Note X to the financial statements in Item 8.

Inflation Reduction Act

On August 16, 2022, the Inflation Reduction Act of 2022 (the Act) was signed into law and included a new 15 percent Corporate Alternative Minimum Tax (CAMT). Under the Act, a corporation is subject to the CAMT if its average annual Adjusted Financial Statement Income (AFSI) for the three taxable year period ending prior to the taxable year exceeds $1,000 million, and applies to tax years beginning after December 31, 2022. Con Edison and CECONY were not subject to the CAMT in 2023 but are expected to be subject to the CAMT in subsequent years.

CON EDISON ANNUAL REPORT 2023 51

However, the provisions of the CAMT are not expected to have a material impact on the Companies’ financial position, results of operations or liquidity.

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. As a result of the sale of the Clean Energy Businesses in 2023, Con Edison has New York State taxable income in excess of $5 million after using its entire New York state net operating loss carryforward, and therefore, the group is subject to the higher 7.25 percent rate (9.425 percent with the surcharge rate) on its taxable income for tax year 2023. As a result of this legislation, CECONY remeasured its deferred tax assets and liabilities that would reverse before 2027 and recorded state deferred income tax expense (net of federal tax benefit) and an increase in accumulated deferred tax liabilities of $10 million for the year ended December 31, 2023, all of which was recorded in the second quarter of 2023.

Operating revenues decreased $95 million in 2023 compared with 2022 primarily due to lower gas purchased for resale expense ($192 million), offset in part by an increase in gas revenues under the company's gas rate plan ($89 million) and higher unbilled revenue accrual ($13 million).

Gas purchased for resale decreased $192 million in 2023 compared with 2022 due to lower purchased volumes ($152 million) and unit costs ($40 million).

CON EDISON ANNUAL REPORT 2023 59

Other operations and maintenance expenses increased $55 million in 2023 compared with 2022 primarily due to higher gas operations costs ($50 million) and higher municipal infrastructure support ($2 million).

Depreciation and amortization increased $62 million in 2023 compared with 2022 primarily due to higher gas utility plant balances.

Taxes, other than income taxes decreased $42 million in 2023 compared with 2022 primarily due to a lower deferral of over-collected property taxes ($35 million) and a lower deferral to levelize the customer bill impact of the gas rate plan ($51 million), offset in part by higher property taxes ($41 million).

Liquidity and Capital Resources

The Companies’ liquidity reflects cash flows from operating, investing and financing activities, as shown on their respective consolidated statements of cash flows and as discussed below.

The principal factors affecting Con Edison’s liquidity are its investments in the Utilities and Con Edison Transmission, the dividends it pays to its shareholders and the dividends it receives from its subsidiaries and cash flows from financing activities discussed below.

The principal factors affecting CECONY’s liquidity are its cash flows from operating activities, cash used in investing activities (including construction expenditures), the dividends it pays to Con Edison and cash flows from financing activities discussed below.

The Companies generally maintain minimal cash balances and use short-term borrowings to meet their working capital needs and other cash requirements. The Companies repay their short-term borrowings using funds from long-term financings and operating activities. The Utilities’ cost of capital, including working capital, is reflected in the rates they charge to their customers.

Each of the Companies believes that it will be able to meet its reasonably likely short-term and long-term cash requirements. See “The Companies Require Access To Capital Markets To Satisfy Funding Requirements,” "Changes To Tax Laws Could Adversely Affect the Companies," “The Companies Face Risks Related to Health Epidemics And Other Outbreaks,” and “The Companies Also Face Other Risks That Are Beyond Their Control” in Item 1A, and “Capital Requirements and Resources” in Item 1.

66 CON EDISON ANNUAL REPORT 2023

Cash Flows from Operating Activities

The Utilities’ cash flows from operating activities primarily reflect their energy sales and deliveries and cost of operations. The volume of energy sales and deliveries is primarily affected by factors external to the Utilities, such as customer demand, weather, market prices for energy and economic conditions. Measures that promote distributed energy resources, such as distributed generation, demand reduction and energy efficiency, also affect the volume of energy sales and deliveries. See "Competition" and "Environmental Matters – Clean Energy Future" and “Environmental Matters – Climate Change” in Item 1.

Pursuant to their rate plans, the Utilities have recovered from customers a portion of the tax liability they will pay in the future as a result of temporary differences between the book and tax basis of assets and liabilities. These temporary differences affect the timing of cash flows, but not net income, as the Companies are required to record deferred tax assets and liabilities at the current corporate tax rate for the temporary differences. For the Utilities, credits to their customers of the net benefits of the TCJA, including the reduction of the corporate tax rate to 21 percent, decrease cash flows from operating activities. Pursuant to their rate plans, the Utilities also recover from customers the amount of property taxes they will pay. The payment of property taxes by the Utilities affects the timing of cash flows and increases the amount of short-term borrowings issued by the Utilities when property taxes are due and as property taxes increase, but generally does not impact net income. See “Changes To Tax Laws Could Adversely Affect the Companies,” in Item 1A, “Federal Income Tax” in Note A, “Rate Plans” in Note B, “Other Regulatory Matters” in Note B and Note L to the financial statements in Item 8 and "Aged Accounts Receivable Balances," above.

On March 1, 2023, Con Edison completed the sale of all of the stock of the Clean Energy Businesses. See Note W and Note X to the financial statements in Item 8.

Net income is the result of cash and non-cash (or accrual) transactions. Only cash transactions affect the Companies’ cash flows from operating activities. Principal non-cash charges or credits include depreciation, deferred income tax expense, amortizations of certain regulatory assets and liabilities and accrued unbilled revenue. Non-cash charges or credits may also be accrued under the revenue decoupling and cost reconciliation mechanisms in the Utilities’ New York electric and gas rate plans. See “Rate Plans – CECONY– Electric and Gas" and "Rate Plans – O&R New York – Electric and Gas” in Note B to the financial statements in Item 8. For Con Edison, 2021 net income also included non-cash losses recognized with respect to impairments of Con Edison Transmission’s investments in MVP, Stagecoach and Honeoye.

Certain prior period amounts have been reclassified within the Companies' cash flows from operating activities to conform with current period presentation.

The change in net cash flows also reflects the timing of payments for and recovery of energy costs. This timing is reflected within changes to accounts receivable – customers, recoverable and refundable energy costs within other regulatory assets and liabilities and accounts payable balances.

Cash Flows Used in Investing Activities

Pursuant to their rate plans, the Utilities recover the cost of utility construction expenditures from customers, including an approved rate of return (before and after being placed in service and an allowance for funds used during construction (AFUDC) before being placed in service).

Net plant at December 31, 2023 was $2,637 million higher than at December 31, 2022. The change in net plant primarily reflects an increase in electric ($2,172 million), gas ($888 million), steam ($150 million) and general ($651 million) plant balances, offset in part by an increase in accumulated depreciation ($1,124 million) and a decrease in construction work in progress ($100 million).

Other noncurrent assets at December 31, 2023 were $715 million higher than at December 31, 2022. The change in other noncurrent assets primarily reflects an increase in the regulatory assets for COVID-19 pandemic deferrals ($393 million), system peak reduction and energy efficiency programs ($258 million) and deferred derivative losses - long term ($122 million), offset in part by a decrease in the regulatory assets for unrecognized pension and other postretirement costs ($78 million). The change in the regulatory asset also reflects the period's amortization of accounting costs. See Notes B, E, and F to the financial statements in Item 8.

See Notes E and F to the financial statements in Item 8.

Long-term debt at December 31, 2023 was $1,730 million higher than at December 31, 2022. The change in long-term debt primarily reflects the 2023 issuances of $2,000 million of debentures, offset in part by the reclassification of $250 million of long-term debt to long-term debt due within one year. See "Liquidity and Capital Resources - Cash Flows From Financing Activities" above and Note C to the financial statements in Item 8.

Equity at December 31, 2023 was $2,268 million higher than at December 31, 2022.

CON EDISON ANNUAL REPORT 2023 73

Regulatory Matters

For information about the Utilities’ rate plans and other regulatory matters affecting the Companies, see “Utility Regulation” in Item 1 and Note B to the financial statements in Item 8.

Risk Factors

The Companies’ businesses are influenced by many factors that are difficult to predict, and that involve uncertainties that may materially affect actual operating results, cash flows and financial condition. See “Risk Factors” in Item 1A.

Critical Accounting Estimates

The Companies’ financial statements reflect the application of certain critical accounting estimates, which conform to accounting principles generally accepted in the United States of America. The Companies’ critical accounting estimates include assumptions applied to accounting for: pensions and other postretirement benefits, contingencies, derivative instruments, allowance for uncollectible accounts receivable, asset retirement obligations and income taxes. Also, see “Summary of Significant Accounting Policies and Other Matters” in Note A to the financial statements in Item 8.

Accounting for Pensions and Other Postretirement Benefits

The Utilities provide pensions and other postretirement benefits to substantially all of their employees and retirees. Con Edison Transmission also provides such benefits to transferred employees who previously worked for the Utilities. The Companies account for these benefits in accordance with the accounting rules for retirement benefits. In addition, the Utilities apply the accounting rules for regulated operations to account for the regulatory treatment of these obligations (which, as described in Note B to the financial statements in Item 8, reconciles the amounts reflected in rates for the costs of the benefit to the costs actually incurred). In applying these accounting policies, the Companies have made critical estimates related to actuarial assumptions, including assumptions of expected returns on plan assets, discount rates, health care cost trends and future compensation. See Notes A, E and F to the financial statements in Item 8 for information about the Companies’ pension and other postretirement benefits, the actuarial assumptions, actual performance, amortization of investment and other actuarial gains and losses and calculated plan costs for 2023, 2022 and 2021.

The discount rate for determining the present value of future period benefit payments is determined using a model to match the durations of Aa rated (by either Moody’s or S&P) corporate bonds with the projected stream of benefit payments.

In determining the health care cost trend rate, the Companies review actual recent cost trends and projected future trends.

The cost of pension and other postretirement benefits in future periods will depend on actual returns on plan assets, assumptions for future periods, contributions and benefit experience. Con Edison’s and CECONY’s current estimates for 2024 are increases, compared with 2023, in their pension and other postretirement benefits costs of $181 million and $168 million, respectively, largely driven by decreases in the discount rates used to determine plan liabilities. See Notes E and F to the financial statements in Item 8.

The following table illustrates the effect on 2024 pension and other postretirement costs of changing the critical actuarial assumptions, while holding all other actuarial assumptions constant:

74 CON EDISON ANNUAL REPORT 2023

(Millions of Dollars)

Increase in accounting cost:

Discount rate

Expected return on plan assets

Future compensation increases

Health care trend rate

Increase in projected benefit obligation:

Discount rate

Future compensation increases

Health care trend rate

A 5 percentage point variation in the actual annual return in 2024, as compared with the expected annual asset return of 6.75 percent, would change pension and other postretirement benefit costs for Con Edison and CECONY by approximately $27 million and $25 million, respectively, in 2025.

Pension benefits are provided through a pension plan maintained by Con Edison to which CECONY, O&R and Con Edison Transmission may make contributions for their participating employees. Pension accounting by the Utilities includes an allocation of plan assets.

The Companies’ policy is to fund their pension and other postretirement benefit accounting costs to the extent tax deductible, and for the Utilities, to the extent these costs are recovered under their rate plans. The Companies were not required to make cash contributions to the pension plan in 2023 under funding regulations and tax laws. However, CECONY and O&R made discretionary contributions to the pension plan in 2023 of $18 million and $3 million, respectively. In 2024, CECONY and O&R expect to make contributions to the pension plan of $9 million and $2 million, respectively. See “Expected Contributions” in Notes E and F to the financial statements in Item 8.

Accounting for Contingencies

The accounting rules for contingencies apply to an existing condition, situation or set of circumstances involving uncertainty as to possible loss that will ultimately be resolved when one or more future events occur or fail to occur. Known material contingencies, which are described in the notes to the financial statements, include certain regulatory matters (Note B), the Utilities’ responsibility for hazardous substances, such as asbestos, PCBs and coal tar that have been used or generated in the course of operations (Note G) and other contingencies (Note H). Inputs to the estimation of the liability for such environmental remediation include the possible selected remedy for each site where investigation is ongoing, the inflation rate related to the cost of inputs to the remediation process, and for those sites where there are other potentially responsible parties, the allocation of costs to the Companies. Inputs to the estimation of the liability for certain regulatory matters include facts specific to each item and the status and progress of discussions with the applicable state regulator. Inputs to the estimation of the liability for other contingencies may include liabilities incurred for similar circumstances and the outcome of legal proceedings. In accordance with the accounting rules, the Companies have accrued estimates of losses relating to the

CON EDISON ANNUAL REPORT 2023 75

contingencies as to which loss is probable and can be reasonably estimated, and no liability has been accrued for contingencies as to which loss is not probable or cannot be reasonably estimated.

The Utilities recover costs for asbestos lawsuits, workers’ compensation and environmental remediation pursuant to their current rate plans. Generally, changes during the terms of the rate plans to the amounts accrued for these contingencies would not impact earnings.

Accounting for Derivative Instruments

The Companies apply the accounting rules for derivatives and hedging to their derivative financial instruments. The Companies use derivative financial instruments to hedge market price fluctuations in related underlying transactions for the physical purchase and sale of electricity and gas. The Utilities are permitted by their respective regulators to reflect in rates all reasonably incurred gains and losses on these instruments. See “Financial and Commodity Market Risks,” below and Note P to the financial statements in Item 8.

Where the Companies are required to make mark-to-market estimates pursuant to the accounting rules, the estimates of gains and losses at a particular period end do not reflect the end results of particular transactions and will most likely not reflect the actual gain or loss at the conclusion of a transaction. Substantially all of the estimated gains or losses are based on prices supplied by external sources such as the fair value of exchange-traded futures and options and the fair value of positions for which price quotations are available through or derived from brokers or other market sources. See Note Q to the financial statements in Item 8.

Allowance for Uncollectible Accounts

The Companies develop expected loss estimates using past events data and consider current conditions and future reasonable and supportable forecasts. For the Utilities’ customer accounts receivable allowance for uncollectible accounts, 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, bankruptcy rates and aged customer accounts receivable balances, among other factors; and forecasts about the future include assumptions related to the level of write-offs and recoveries. From January 1, 2020 to December 31, 2023, the historical write-off rate was determined based on an historical weather event with a significant impact to the Companies’ service territory. During that period, Con Edison's and CECONY's allowances for uncollectible accounts increased from $70 million and $65 million, respectively to $360 million and $353 million, respectively. See "COVID-19 Regulatory Matters" in Note B and “Allowance for Uncollectible Accounts" in Note N to the financial statements in Item 8.

Asset Retirement Obligations (AROs)

AROs are computed as the present value of the estimated costs for an asset's future retirement and are recorded in the period in which the liability is incurred. The estimated costs are capitalized as part of the related long-lived asset and depreciated over the asset's useful life. CECONY and O&R, as rate-regulated entities, recognize Regulatory Assets or Liabilities as a result of timing differences between the recording of costs and costs recovered through the ratemaking process. Because quoted market prices are not available for AROs, the Companies estimate the fair value of AROs by calculating discounted cash flows that are dependent upon various assumptions including estimated retirement dates, discount rates, inflation rates, the timing and amount of future cash outlays, and currently available technologies.

The Companies recorded asset retirement obligations associated with the removal of asbestos and asbestos-containing material in their buildings (other than the structures enclosing generating stations and substations), electric equipment and steam and gas distribution systems. The Companies also recorded asset retirement obligations relating to gas and oil pipelines abandoned in place and municipal infrastructure support. See Note T to the financial statements in Item 8.

A 1 percent increase in the assumed inflation rate used to value the ARO liability as of December 31, 2023 would increase the liability by $40 million for Con Edison and CECONY.

Accounting for Income Taxes

The Companies record provisions for income taxes, deferred tax assets and liabilities, and a valuation allowance against net deferred tax assets, if any. The reporting of tax-related assets and liabilities requires the use of estimates and significant judgments by management. Deferred tax assets and liabilities are recorded to represent future effects on income taxes for temporary differences between the basis of assets for financial reporting and tax purposes. Although management believes that current estimates for deferred tax assets and liabilities are

76 CON EDISON ANNUAL REPORT 2023

reasonable, actual results could differ materially from these estimates for several reasons, including, but not limited to: a change in forecasted financial condition and/or results of operations; changes in income tax laws, enacted tax rates or amounts subject to income tax or state apportionments; the form, structure, and timing of asset or stock sales or dispositions; changes in the regulatory treatment of any tax reform benefits; and changes resulting from audits and examinations by taxing authorities. Valuation allowances against deferred tax assets are recorded when management concludes it is more likely than not such asset will not be realized in future periods. Accounting for income taxes also requires that only tax benefits for positions taken or expected to be taken on tax returns that meet the more-likely-than-not recognition threshold can be recognized or continue to be recognized. Management evaluates each position solely on the technical merits and facts and circumstances of the position, assuming that the position will be examined by a taxing authority that has full knowledge of all relevant information. Significant judgment is required to determine recognition thresholds and the related amount of tax benefits to be recognized. At each period end, and as new developments occur, management reevaluates its tax positions. Additional interpretations, regulations, amendments, or technical corrections related to the federal income tax code as a result of the Inflation Reduction Act, may impact the estimates for income taxes discussed above. See “Changes To Tax Laws Could Adversely Affect the Companies” in Item 1A, “Inflation Reduction Act” above, “Federal Income Tax” and “State Income Tax” in Note A and Note L to the financial statements in Item 8.

Financial and Commodity Market Risks

The Companies are subject to various risks and uncertainties associated with financial and commodity markets. The most significant market risks include interest rate risk, commodity price risk and investment risk.

Interest Rate Risk

The Companies' interest rate risk primarily relates to new debt financing needed to fund capital requirements, including the construction expenditures of the Utilities and maturing debt securities, and variable-rate debt. Con Edison and its subsidiaries manage interest rate risk through the issuance of mostly fixed-rate debt with varying maturities and through opportunistic refinancing of debt. Con Edison and CECONY estimate that at December 31, 2023, a 10 percent increase in interest rates applicable to its variable rate debt would result in an increase in annual interest expense of $15 million and $12 million, respectively. At December 31, 2022, Con Edison and CECONY estimated that a 10 percent increase in interest rates applicable to its variable rate debt would result in an increase in annual interest expense of $17 million and $13 million, respectively. Under CECONY’s current electric, gas and steam rate plans, variations in actual variable rate tax-exempt debt interest expense, including costs associated with the refinancing of the variable rate tax-exempt debt, are reconciled to levels reflected in rates.

Inflationary pressure has prompted the Federal Reserve to increase interest rates. Higher interest rates have resulted in, and are expected to continue to result in, increased interest expense on commercial paper, variable-rate debt and long-term debt issuances.

Commodity Price Risk

Con Edison’s commodity price risk primarily relates to the purchase and sale of electricity, gas and related derivative instruments. The Utilities apply risk management strategies to mitigate their related exposures. See Note P to the financial statements in Item 8.

Con Edison estimates that, as of December 31, 2023, a 10 percent decline in market prices would result in a decline in fair value of $149 million for the derivative instruments used by the Utilities to hedge purchases of electricity and gas, of which $138 million is for CECONY and $11 million is for O&R. As of December 31, 2022, Con Edison estimated that a 10 percent decline in market prices would result in a decline in fair value of $214 million for the derivative instruments used by the Utilities to hedge purchases of electricity and gas, of which $199 million is for CECONY and $15 million is for O&R. Con Edison expects that any such change in fair value would be largely offset by directionally opposite changes in the cost of the electricity and gas purchased.

The Utilities do not make any margin or profit on the electricity or gas they sell. In accordance with provisions

approved by state regulators, the Utilities generally recover from full-service customers the costs they incur for energy purchased for those customers, including gains and losses on certain derivative instruments used to hedge energy purchased and related costs. See “Recoverable Energy Costs” in Note A to the financial statements in Item 8. However, increases in electric and gas commodity prices may contribute to a slower recovery of cash from outstanding customer accounts receivable balances.

CON EDISON ANNUAL REPORT 2023 77

Investment Risk

The Companies’ investment risk relates to the investment of plan assets for their pension and other postretirement benefit plans. Con Edison's investment risk also relates to the investments of Con Edison Transmission that are accounted for under the equity method. See “Critical Accounting Estimates – Accounting for Pensions and Other Postretirement Benefits,” above and “Investments” in Note A and Notes E and F to the financial statements in Item 8.

The Companies’ current investment policy for pension plan assets includes investment targets of 26 to 30 percent equity securities, 42 to 60 percent debt securities, 14 to 30 percent alternatives. At December 31, 2023, the pension plan investments consisted of 26 percent equity securities, 50 percent debt securities and 24 percent alternatives.

For the Utilities’ pension and other postretirement benefit plans, regulatory accounting treatment is generally applied in accordance with the accounting rules for regulated operations. In accordance with the Statement of Policy issued by the NYSPSC and its current electric, gas and steam rate plans, CECONY defers for payment to or recovery from customers the difference between the pension and other postretirement benefit expenses and the amounts for such expenses reflected in rates. O&R also defers such difference pursuant to its New York rate plans.

Environmental Matters

For information concerning climate change, environmental sustainability, potential liabilities arising from laws and regulations protecting the environment and other environmental matters, see “Environmental Matters” in Item 1 and Note G to the financial statements in Item 8.

Material Contingencies

For information concerning potential liabilities arising from the Companies’ material contingencies, see “Critical Accounting Estimates – Accounting for Contingencies,” above, and Notes B, G and H to the financial statements in Item 8.

Report of Management on Internal Control Over Financial Reporting

Management of Consolidated Edison, Inc. and its subsidiaries (the Company) is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is a process designed to provide reasonable, but not absolute, assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of the effectiveness of controls to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with policies or procedures may deteriorate.

Management of the Company assessed the effectiveness of internal control over financial reporting as of December 31, 2023, using the criteria established by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control — Integrated Framework (2013). Based on that assessment, management has concluded that the Company had effective internal control over financial reporting as of December 31, 2023.

The effectiveness of the Company’s internal control over financial reporting as of December 31, 2023, has been audited by PricewaterhouseCoopers LLP, the Company’s independent registered public accounting firm, as stated in their report which appears on the following page of this Annual Report on Form 10-K.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of Consolidated Edison, Inc.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the consolidated financial statements, including the related notes and financial statement schedule, of Consolidated Edison, Inc. and its subsidiaries (the “Company”) as listed in the index appearing under Item 8 (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Report of Management on Internal Control Over Financial Reporting. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

82 CON EDISON ANNUAL REPORT 2023

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Accounting for the Effects of Regulatory Matters

As described in Notes A and B to the consolidated financial statements, the Company applies the accounting rules for regulated operations, which specifies the economic effects that result from the causal relationship of costs and revenues in the rate-regulated environment and how these effects are to be accounted for by a regulated enterprise. As of December 31, 2023, there were $4,888 million of deferred costs included in regulatory assets and $5,473 million of regulatory liabilities awaiting potential refund or future rate reductions. Under regulatory accounting rules, if it is probable that incurred costs will be recovered in the future, those costs would be recorded as deferred charges or “regulatory assets.” Similarly, if revenues are recorded for costs expected to be incurred in the future, these revenues would be recorded as deferred credits or “regulatory liabilities.” The Company’s regulatory assets and liabilities will be recovered from customers, or applied for customer benefit, in accordance with rate provisions approved by the applicable state regulators.

The principal considerations for our determination that performing procedures relating to the accounting for the effects of regulatory matters is a critical audit matter are the significant judgment by management in determining the recoverability of certain regulatory assets and the significant auditor judgment and subjectivity in performing procedures and evaluating audit evidence relating to the recognition of regulatory assets and regulatory liabilities, including evaluating management’s judgments relating to the recoverability of certain regulatory assets.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to management’s assessment of regulatory proceedings and the implementation of new regulatory orders or changes to existing regulatory balances. These procedures also included, among others, evaluating the reasonableness of management’s assessment of impacts arising from correspondence with regulators and changes in laws and regulations; evaluating management’s judgments related to the recoverability of regulatory assets and the establishment of regulatory liabilities; and recalculating regulatory assets and liabilities based on provisions and formulas outlined in rate orders and other correspondence with regulators.
