Available Information On August 1, 2024, Consolidated Edison, Inc. issued a press release reporting its second quarter 2024 earnings and filed with the Securities and Exchange Commission the company’s second quarter 2024 Form 10-Q. This presentation should be read together with, and is qualified in its entirety by reference to, the earnings press release and the Form 10-Q. Copies of the earnings press release and the Form 10-Q are available at: www.conedison.com/en/. (Select “For Investors” and then select “Press Releases” and “SEC Filings,” respectively.) Forward-Looking Statements This presentation contains forward-looking statements that are intended to qualify for the safe-harbor provisions of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements are statements of future expectations and not facts. Words such as “forecasts,” “expects,” “estimates,” “anticipates,” “intends,” “believes,” “plans,” “will,” “target,” “guidance,” “potential,” “goal,” “consider” and similar expressions identify forward-looking statements. The forward-looking statements reflect information available and assumptions at the time the statements are made, and accordingly speak only as of that time. Actual results or developments might differ materially from those included in the forward-looking statements because of various factors such as those identified in reports Con Edison has filed with the Securities and Exchange Commission, including that Con Edison's subsidiaries are extensively regulated and are subject to substantial penalties; its utility subsidiaries' rate plans may not provide a reasonable return; it may be adversely affected by changes to the utility subsidiaries' rate plans; the failure of, or damage to, its subsidiaries' facilities could adversely affect it; a cyber-attack could adversely affect it; the failure of processes and systems, the failure to retain and attract employees and contractors, and their negative performance could adversely affect it; it is exposed to risks from the environmental consequences of its subsidiaries' operations, including increased costs related to climate change; its ability to pay dividends or interest depends on dividends from its subsidiaries; changes to tax laws could adversely affect it; it requires access to capital markets to satisfy funding requirements; a disruption in the wholesale energy markets, increased commodity costs or failure by an energy supplier or customer could adversely affect it; it faces risks related to health epidemics and other outbreaks; its strategies may not be effective to address changes in the external business environment; it faces risks related to supply chain disruptions and inflation; and it also faces other risks that are beyond its control. This list of factors is not all-inclusive because it is not possible to predict all factors. Con Edison assumes no obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law. Non-GAAP Financial Measures This presentation also contains financial measures, adjusted earnings and adjusted earnings per share (adjusted EPS), that are not determined in accordance with generally accepted accounting principles in the United States of America (GAAP). These non-GAAP financial measures should not be considered as an alternative to net income for common stock or net income per share, respectively, each of which is an indicator of financial performance determined in accordance with GAAP. Adjusted earnings and adjusted earnings per share exclude from net income for common stock and net income per share, respectively, certain items that Con Edison does not consider indicative of its ongoing financial performance such as adjustments to the gain and other impacts related to the sale of all of the stock of its former subsidiary the Clean Energy Businesses in 2023, the effects of HLBV accounting for tax equity investments and mark-to-market accounting. Management uses these non-GAAP financial measures to facilitate the analysis of Con Edison's financial performance as compared to its internal budgets and previous financial results and to communicate to investors and others Con Edison's expectations regarding its future earnings and dividends on its common stock. Management believes that these non-GAAP financial measures are also useful and meaningful to investors to facilitate their analysis of Con Edison's financial performance. See slides 13, 17, 18, 22, 26, 27, and 28 for a reconciliation of non-GAAP financial measures to their GAAP equivalent.

Under the revenue decoupling mechanisms in the Utilities’ New York electric and gas rate plans and the weather-normalization clause applicable to their gas businesses, revenues are generally not affected by changes in delivery volumes from levels assumed when rates were approved. Effective November 1, 2023, revenues from CECONY’s steam sales are also subject to a weather normalization clause, as a result of which, delivery revenues reflect normal weather conditions during the heating season. In general, the Utilities recover on a current basis the fuel, gas purchased for resale and purchased power costs they incur in supplying energy to their full-service customers. Accordingly, such costs do not generally affect Con Edison’s results of operations. 15

2Q 2024 Developments(a) CECONY & O&R In April 2024, O&R filed an update to its January 2024 request to the NYSPSC for an electric rate increase effective January 1, 2025. The company decreased its requested January 2024 rate increase by $7.5 million to $10.7 million. For purposes of illustration, the filing calculated rate increases of $34.8 million and $55 million effective January 2026 and 2027, respectively, based upon the proposed return on common equity of 10.25 percent and a common equity ratio of 50 percent. In May 2024, the New York State Department of Public Service (NYSDPS) submitted testimony in the NYSPSC proceeding in which O&R requested an electric rate increase, effective January 1, 2025. The NYSDPS testimony supports an electric rate decrease of $27.6 million reflecting, among other things, a 9.50 percent return on common equity and a common equity ratio of 48 percent. (page 22) In April 2024, O&R filed an update to its January 2024 request to the NYSPSC for a gas rate increase effective January 1, 2025. The company increased its requested January 2024 rate increase by $3.1 million to $17.5 million. For purposes of illustration, the filing calculated rate increases of $22.8 million and $19.2 million effective January 2026 and 2027, respectively, based upon the proposed return on common equity of 10.25 percent and a common equity ratio of 50 percent. In May 2024, the NYSDPS submitted testimony in the NYSPSC proceeding in which O&R requested a gas rate increase, effective January 1, 2025. The NYSDPS testimony supports a gas rate decrease of $2.9 million reflecting, among other things, a 9.50 percent return on common equity and a common equity ratio of 48 percent. (page 22) In May 2024, the NYSPSC issued an order denying an April 2023 petition by CECONY that requested permission to capitalize costs to implement its new customer billing and information system to the extent those costs exceeded the $421 million cap established in CECONY’s 2020 – 2022 electric and gas rate plans. CECONY’s final costs for the new system were $510 million ($89 million above the $421 million cap in the rate plans). CECONY believes that the incremental costs were both prudent and necessary for the successful deployment of the system for the benefit of its customers. In May 2024, CECONY expensed incremental costs of $51 million for the new system that were previously capitalized, in addition to a $38 million reserve established at December 31, 2023. In June 2024, CECONY filed a petition for rehearing with the NYSPSC. CECONY is unable to predict the NYSPSC's response to its rehearing petition. (page 23) In May 2024, CECONY filed its inaugural annual Investing in Disadvantaged Communities Report, as required by the NYSPSC. The report summarizes the impacts of CECONY's investments in disadvantaged communities (DACs) within the company’s service territory, based on 2023 data. The report includes, among other things, building electrification and energy efficiency initiatives, as well as data related to the company’s long-running electric and gas operations. DAC locations were identified by New York State in connection with the implementation process for the CLCPA. (page 77) At June 30, 2024, CECONY’s and O&R’s customer accounts receivables balances of $2,742 million and $117 million, respectively, included aged accounts receivables (balances outstanding in excess of 60 days) of $1,553 million and $37 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 (balances outstanding in excess of 60 days) of $408 million and $15 million, respectively. (page 49) In June 2024, CECONY reached a four-year collective bargaining agreement with its largest union covering approximately 7,300 employees (which is subject to ratification by the employees).(page 50) In June 2024, CECONY decreased its five-year forecast of average annual growth of the firm peak gas demand in its service area at design conditions from approximately 0.8 percent (for 2024 to 2028) to approximately 0.1 percent (for 2025 to 2029). The decrease is reflective of and aligned with state and local clean energy future policies driving the phase-out of the use of natural gas. (page 50) a. Page references to 2Q 2024 Form 10-Q unless noted otherwise. 19

2Q 2024 Developments (continued)(a) a. Page references to 2Q 2024 Form 10-Q unless noted otherwise. 20 CECONY & O&R In June 2024, CECONY increased its five-year forecast of the average annual peak steam demand in its service area at design conditions from a 0.5 percent decrease (for 2024 to 2028) to a 0.4 percent decrease (for 2025 to 2029). The increase is reflective of and aligned with local policies driving the phase-out of the use of natural gas along with an anticipated increase in oil-to-steam customer conversions. (page 50) In June 2024, O&R increased its five-year forecast of the average annual firm peak gas demand in its service area at design conditions from a 0.2 percent decrease (for 2024 to 2028) to a 0.1 percent decrease (for 2025 to 2029). This change is reflective of and aligned with state clean energy future policies driving the phase-out of the use of natural gas. (page 50) In April 2024, the NYSDPS approved CECONY’s and O&R’s December 2023 Stage 1 filings (Project Scope, Feasibility, and Stakeholder Engagement) for utility-scale thermal energy network pilot projects. The NYSDPS also confirmed CECONY and O&R are authorized to incur costs of $17.1 million and $4.6 million, respectively, through the completion of Stage 2 (Pilot Project Engineering Design and Customer Protection Plan). These projected costs are within the budgets proposed by CECONY and O&R of $255 million and $46 million, respectively. The remaining proposed budget amounts are subject to approval by the NYSPSC. (page 78) Con Edison Transmission In June 2024, the Mountain Valley Pipeline, a 303-mile gas transmission pipeline in West Virginia and Virginia, entered service. The project operator is continuing restoration of the right of way and estimates a total project cost of approximately $7,900 million (excluding allowance for funds used during construction (AFUDC)). Con Edison Transmission's interest in MVP, the company that developed the project, is expected to be approximately 6.7 percent. At June 30, 2024, the carrying value of Con Edison Transmission's investment in MVP was $156 million. and its cash contributions to the joint venture amounted to $530 million. Con Edison records its pro rata share of earnings from its equity investment in MVP, adjusted for accretion of basis difference and income taxes, on its consolidated income statement.

Under the revenue decoupling mechanisms in the Utilities’ New York electric and gas rate plans and the weather- normalization clause applicable to their gas businesses, revenues are generally not affected by changes in delivery volumes from levels assumed when rates were approved. Effective November 1, 2023, revenues from CECONY’s steam sales are also subject to a weather normalization clause, as a result of which, delivery revenues reflect normal weather conditions during the heating season. In general, the Utilities recover on a current basis the fuel, gas purchased for resale and purchased power costs they incur in supplying energy to their full-service customers. Accordingly, such costs do not generally affect Con Edison’s results of operations. YTD 2024 vs. YTD 2023 EPS and Adjusted EPS (non- GAAP) Variances – Six Months Ended Variation 23
