2nd Quarter 2025 Earnings Release Presentation August 7, 2025

Available Information On August 7, 2025, Consolidated Edison, Inc. issued a press release reporting its second quarter 2025 earnings and filed with the Securities and Exchange Commission the company’s second quarter 2025 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 may be 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, inflation and the imposition of tariffs (or subsequent changes to tariffs once announced or implemented); 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 that could cause actual results or developments to differ from the forward-looking statements. 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, Con Edison Clean Energy Businesses, Inc. (the Clean Energy Businesses), in 2023, the effects of hypothetical liquidation at book value (HLBV) accounting for tax equity investments and accretion of the basis difference of Con Edison's equity investment in Mountain Valley Pipeline, LLC (MVP). 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 18, 22, 23, 27, 31, 32 and 33 for a reconciliation of non-GAAP financial measures to their GAAP equivalent.

Customer Affordability CECONY electric customer bills are lower than our proxy peer average on both a total bill and share of wallet basis 12 Source: S&P Market Intelligence, EIA. Three-year (2021 - 2023) average customer bills are annualized full-service residential bills. Share of wallet calculated as annual bill over median household income.

Providing Bill Relief to Customers Who Need It Most Approximately 459,000 CECONY and O&R customers, or 14% of the customer base, are enrolled in our Energy Affordability Programs (EAP) and we advocated to expand the EAP to support additional low- and moderate-income customers 13 • Customers enrolled in CECONY's and O&R's Energy Affordability Programs (EAP) receive bill discounts aimed at reducing energy burden to 6% of wallet • As of June 2025, approximately 14% of residential customers across CECONY's and O&R's service territories were enrolled in the EAP • Over the course of 2024, CECONY's and O&R's EAP provided $333 million in discounts to help make bills more affordable for our most vulnerable customers • In July 2025, the NYSPSC issued an order to expand the EAP to provide bill discounts to income-qualified low- and moderate-income residential customers who are not otherwise eligible for the EAP today

NYSPSC & NYISO Proceedings and Developments 14 Gas System Long Term Plan(b) • In May 2025, CECONY and O&R submitted the annual update to their combined gas system long-term plan (GSLTP) that was filed in November 2023. In addition to the annual updates, the filing contained a system planning update with details on potential long-term impacts to revenue requirements, load forecasts, program changes, data on actual customer usage, a framework for scaling back the Utilities’ long-term contracts for natural gas supply, updates on disadvantaged communities and development of a definition of “hard-to- electrify customers.” The Utilities are required to periodically file these long-term plans and the next iteration of the GSLTP is due in August 2027. Steam Decarbonization Projects Petition(c) • In May 2025, CECONY filed a petition with the NYSPSC for authorization and cost recovery for the early deployment of four steam decarbonization projects at an estimated cost of $332 million and for authorization to implement a low carbon fuels pilot program that will procure locally-sourced renewable natural gas for use in generating steam. CECONY requested that the NYSPSC approve its petition by September 2025. Energy Efficiency Programs Approval(a) • In May 2025, the NYSPSC issued two orders that established budgets for CECONY’s and O&R’s energy efficiency and building electrification programs (formerly known as New Efficiency New York), formerly known as New Efficiency New York, for 2026-2030 with aggregate budgets of approximately $2,140 million and $110 million, respectively. The aggregate amounts are comprised of average annual budgets of: $300 million and $19 million for electric energy efficiency and heat pump programs for CECONY and O&R, respectively, and $128 million and $3 million for gas energy efficiency programs for CECONY and O&R, respectively. Energy efficiency and building electrification expenditures are treated as regulatory assets with recovery including the weighted average cost of capital and beginning in 2026 via a surcharge rather than included in base rates. Disadvantaged Communities Report(e) • In May 2025, CECONY filed with the NYSPSC its second annual Investing in Disadvantaged Communities Report, summarizing the CECONY's 2024 investments, program outcomes and impacts in Disadvantaged Communities across its service territory. Clean Energy Standard Biennial Review(d) • In May 2025, the NYSPSC adopted the Clean Energy Standard Biennial Review as final. The review, which is required by the Climate Leadership and Community Protection Act, is intended to track the State's progress in meeting renewable energy goals. The review acknowledged that the State is not on target to achieve its goal of 70 percent renewable energy by 2030. Considering the shortfall, the NYSPSC determined that there is value in exploring the option of utility-owned renewables as a potential avenue to achieve the State's ambitious clean energy goals and requested responses to eight questions related to utility-owned generation. The NYSPSC is expected to provide recommendations on utility ownership of large-scale renewables as part of their comprehensive evaluation of the Clean Energy Standard's procurement structure in May 2026. The next Biennial Review will occur in 2026. a. NYSPSC docket number 18-M-0084 b. NYSPSC docket number 23-G-0147 c. NYSPSC docket number 25-S-0350 d. NYSPSC docket number 15-E-0302 e.

NYSPSC & NYISO Proceedings and Developments (continued) 15 Proactive Planning for Upgraded Electric Grid Infrastructure(b) • In June 2025, the NYSPSC approved five of the nine urgent proactive planning projects proposed by CECONY in its November 2024 filing for grid upgrades needed to meet anticipated demand from transportation and building heating electrification. The total estimated capital costs for the five new urgent projects are $439.9 million. The NYSPSC indicated that the remaining urgent projects not approved may be pursued as part of a rate case, through the yet to be established proactive planning framework study process, or through another relevant generic proceeding. All nine proposed projects were included in the CECONY 2025 rate filing. Enhanced Energy Affordability Program Pilot(a) • In June 2025, CECONY and O&R, with other New York utilities, filed comments on the Department of Public Service Staff's proposed two-year Enhanced Energy Affordability Program (EEAP) pilot. The pilot, which Staff proposes to begin on December 1, 2025, would expand the existing Energy Affordability Program to low- and moderate-income customers experiencing affordability challenges who are not eligible for the current program. In July 2025, the NYSPSC issued an order to expand the Energy Affordability Program, which will begin accepting applications for the EEAP program starting in January 2026. Cybersecurity Rules for Information Technology(c) • In June 2025, the NYSPSC initiated a proceeding to establish cybersecurity regulations for information technology (IT) systems used by public utilities and cable television companies. The draft regulations require entities to adopt risk-based cybersecurity practices to mitigate the risks of cyberattacks. Interested stakeholders are invited to submit comments on the proposed cybersecurity requirements by September 15, 2025. a. NYSPSC docket number 14-M-0565 and 23-M-0298 b. NYSPSC docket number 24-E-0364 c. NYSPSC docket number 25-M-0302 d. NYSPSC docket number 22-E-0633 New York City Public Policy Transmission Need (d) • In July 2025, the NYSPSC issued an order withdrawing the PPTN process given actions taken by the federal government that reduced the prospects for the construction of the offshore wind resources that were anticipated to be served by the proposed transmission solutions. The NYSPSC’s decision does not, however, affect previously permitted offshore wind projects in New York, including Sunrise Wind (924 MW), a project that began construction in June 2024 and is expected to enter commercial operation in 2026 and Empire Wind 1 (810 MW), a project that is expected to enter commercial operation in 2027 and connect to the New York City electrical grid at CECONY’s Gowanus substation. Utility-Scale Thermal Energy Network Pilot Project (e) • In July 2025, CECONY and O&R filed with the NYSPSC their final Pilot Engineering Design and Customer Protection Plans (Stage 2 Filings) for the utility-scale thermal energy network (UTEN) pilot project. CECONY and O&R requested authorization to proceed to Stage 3 (Customer Enrollment and Construction). The total estimated costs for the UTEN projects have increased to $415 million (from $255 million) and $112 million (from $46 million) for CECONY and O&R, respectively. CECONY and O&R were previously authorized to incur costs of $23.1 million and $4.6 million, respectively. The remaining proposed budget amounts in excess of the previously authorized amounts are subject to approval by the NYSPSC. e. NYSPSC docket number 22-M-0429

Under the revenue decoupling mechanisms in the Utilities’ New York electric and gas rate plans, revenues are generally not affected by changes in delivery volumes from levels assumed when rates were approved. The Utilities' gas and CECONY’s steam sales are 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. 20

2Q 2025 Developments(a) CECONY & O&R In January 2025, as updated in April 2025, CECONY filed requests with the NYSPSC for electric and gas rate increases of $1,608 million and $349 million, respectively, effective January 1, 2026. The filings reflect a return on common equity of 10 percent and a common equity ratio of 48 percent. In May 2025, the New York State Department of Public Service submitted testimony in the pending electric and gas rate case proceedings, supporting an electric rate increase of $319 million and a gas rate decrease of $45 million, reflecting, among other things, a 9.30 percent return on common equity and a common equity ratio of 48 percent. CECONY’s future earnings will depend on the rates authorized in, and the other provisions of, its January 2026 electric and gas rate plans and CECONY’s ability to operate its businesses in a manner consistent with such rate plans. Therefore, the outcome of CECONY’s rate requests, which require approval by the NYSPSC, will impact the Companies’ future financial condition, results of operations and liquidity. (pages 21, 48) In May 2025, CECONY filed a petition with the NYSPSC for authorization and cost recovery for the early deployment of four steam decarbonization projects at an estimated cost of $332 million and for authorization to implement a low carbon fuels pilot program that will procure locally-sourced renewable natural gas for use in generating steam. CECONY requested that the NYSPSC approve its petition by September 2025. (page 21) In May 2025, CECONY and O&R submitted the annual update to their combined gas system long-term plan (GSLTP) that was filed in November 2023. In addition to the annual updates, the filing contained a system planning update with details on potential long-term impacts to revenue requirements, load forecasts, program changes, data on actual customer usage, a framework for scaling back the Utilities’ long-term contracts for natural gas supply, updates on disadvantaged communities and development of a definition of “hard-to-electrify customers.” The Utilities are required to periodically file these long-term plans and the next iteration of the GSLTP is due in August 2027. (page 78) In May 2025, the NYSPSC issued two orders that established budgets for CECONY’s and O&R’s energy efficiency and building electrification programs (formerly known as New Efficiency New York) for 2026-2030 with aggregate budgets of approximately $2,140 million and $110 million, respectively. The aggregate amounts are comprised of average annual budgets of: $300 million and $19 million for electric energy efficiency and heat pump programs for CECONY and O&R, respectively, and $128 million and $3 million for gas energy efficiency programs for CECONY and O&R, respectively. Energy efficiency and building electrification expenditures are treated as regulatory assets with recovery including the weighted average cost of capital and beginning in 2026 via a surcharge rather than included in base rates. (page 79) In May 2025, New York adopted the 2025-2026 budget bill into law that included increases in payroll tax rates from 0.6 percent to 0.895 percent for CECONY and from 0.34 percent to 0.635 percent for O&R, effective July 1, 2025. (page 51) a. Page references to 2025 2nd Quarter Form 10-Q unless noted otherwise. 24 Con Edison 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 (TCJA) and expanding certain incentives under the federal Inflation Reduction Act, as enacted on August 16, 2022 (IRA) while accelerating the phase-out of solar and wind credits. The Companies are assessing 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 preliminary assessment, the provisions in the OBBBA are not expected to have a material impact on the Companies’ financial position, results of operations or liquidity. (pages 32, 51)

2Q 2025 Developments (continued)(a) a. Page references to 2025 2nd Quarter Form 10-Q unless noted otherwise. 25 CECONY & O&R In June 2025, RECO filed a request with the New Jersey Board of Public Utilities for an electric rate increase of $18.7 million, effective January 2026. The filing reflected a return on common equity of 10% and a common equity ratio of 50%. In August 2025, RECO filed an update to the request it filed in June 2025. The company increased its requested January 2026 rate increase to $23.3 million and changed the common equity ratio to 50.12 percent. The updated filing continues to reflect a return on common equity of 10.30 percent. (page 21) At June 30, 2025, CECONY’s and O&R’s customer accounts receivables balances of $2,892 million and $116 million, respectively, included aged accounts receivables (balances outstanding in excess of 60 days) of $1,530 million and $26 million, respectively. At December 31, 2024, CECONY’s and O&R’s customer accounts receivables balances of $2,947 million and $113 million, respectively, included aged accounts receivables (balances outstanding in excess of 60 days) of $1,652 million and $32 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 48) In June 2025, the NYSPSC approved five of the nine urgent proactive planning projects proposed by CECONY in its November 2024 filing for grid upgrades needed to meet anticipated demand from transportation and building heating electrification. The total estimated capital costs for the five new urgent projects are $439.9 million. The NYSPSC indicated that the remaining urgent projects not approved may be pursued as part of a rate case, through the yet to be established proactive planning framework study process, or through another relevant generic proceeding. All nine proposed projects were included in the CECONY 2025 rate filing. (page 78) In June 2025, CECONY increased its five-year forecast of average annual growth of the firm peak gas demand in its service area at design conditions from approximately 0.1 percent (for 2025 to 2029) to approximately 0.2 percent (for 2026 to 2030). (page 50) In June 2025, CECONY changed its five-year forecast of the average annual peak steam demand in its service area at design conditions from a 0.4 percent decrease (for 2025 to 2029) to a 0.9 percent decrease (for 2026 to 2030). This percent change indicates lower customer retention for the steam system due to policy and regulations along with increased levels of energy efficiency within the next five years. (page 50) In June 2025, O&R increased its five-year forecast of the average annual firm peak gas demand in its service area at design conditions from a 0.1 percent decrease (for 2025 to 2029) to a 1.2 percent increase (for 2026 to 2030). This change reflects an increase in new business within the next five years. (pages 50-51) In July 2025, the NYSPSC issued an order withdrawing the PPTN process given actions taken by the federal government that reduced the prospects for the construction of the offshore wind resources that were anticipated to be served by the proposed transmission solutions. The NYSPSC’s decision does not, however, affect previously permitted offshore wind projects in New York, including Sunrise Wind (924 MW), a project that began construction in June 2024 and is expected to enter commercial operation in 2026 and Empire Wind 1 (810 MW), a project that is expected to enter commercial operation in 2027 and connect to the New York City electrical grid at CECONY’s Gowanus substation. (page 79)

2Q 2025 Developments (continued)(a) a. Page references to 2025 2nd Quarter Form 10-Q unless noted otherwise. 26 Con Edison Transmission As of June 30, 2025, Con Edison Transmission's interest in MVP, the company that developed the project, is approximately 6.6 percent based on Con Edison Transmission's previous capping of its cash contributions. At June 30, 2025, the carrying value of Con Edison Transmission's investment in MVP was $164 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 the basis difference and income taxes, on its consolidated income statement. Con Edison's pro rata share of earnings from its equity investment in MVP, adjusted for accretion of the basis difference, was $7 million ($5 million after-tax) and $15 million ($11 million after-tax) for the three and six months ended June 30, 2025, respectively. (page 19) CECONY & O&R In July 2025, the FERC granted CECONY’s request for the abandoned plant and construction work in progress (CWIP) incentives for certain breakers at the Rainey substation in Queens, New York that CECONY has been designated to construct as part of the Propel NY Energy project that is being developed by NYPA and New York Transco, effective July 14, 2025. CECONY will recover all of its prudently incurred costs associated with the breakers if the installation is cancelled or abandoned for reasons beyond CECONY’s control and CECONY will recover all of the CWIP incentive in rate base during the development and construction phase of the breakers. (pages 78-79) In July 2025, CECONY and O&R filed with the NYSPSC their final Pilot Engineering Design and Customer Protection Plans (Stage 2 Filings) for the utility-scale thermal energy network (UTEN) pilot project. CECONY and O&R requested authorization to proceed to Stage 3 (Customer Enrollment and Construction). The total estimated costs for the UTEN projects have increased to $415 million (from $255 million) and $112 million (from $46 million) for CECONY and O&R, respectively. CECONY and O&R were previously authorized to incur costs of $23.1 million and $4.6 million, respectively. The remaining proposed budget amounts in excess of the previously authorized amounts are subject to approval by the NYSPSC. (page 79)

Under the revenue decoupling mechanisms in the Utilities’ New York electric and gas rate plans, revenues are generally not affected by changes in delivery volumes from levels assumed when rates were approved. The Utilities' gas and CECONY’s steam sales are 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.
