1st Quarter 2025 Earnings Release Presentation May 1, 2025

Available Information On May 1, 2025, Consolidated Edison, Inc. issued a press release reporting its first quarter 2025 earnings and filed with the Securities and Exchange Commission the company’s first 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; 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 17, 21, 22 and 25 for a reconciliation of non-GAAP financial measures to their GAAP equivalent.

CECONY’s and O&R’s updated climate change resilience plans propose investments of $645.4 million and $184.1 million, respectively, between 2025 and 2029 to enhance the resilience of their electric systems against extreme weather events brought about by climate change. The total cost of CECONY’s and O&R’s climate resilience investments from 2025 through 2044 are currently projected to be $5,294 million and $900.4 million, respectively. These investments are subject to approval by the NYSPSC through the base rate case process. c. NYSPSC docket number 22-E-0222 d. NYSPSC docket number 25-M-0043 NYC Public Policy Transmission Need (PPTN) • In December 2024, the NYSPSC initiated a process to evaluate whether to continue, modify, or cancel the NYC PPTN. The NYISO has already conducted both the facility characterization analysis and viability and sufficiency assessment of the 28 submitted project proposals. The NYSPSC has the opportunity at any time prior to the NYISO's selection to modify or cancel the need. ◦ In response, CECONY, O&R, and CET submitted comments(a) in February 2025, supporting the continuation of the NYC PPTN process, highlighting the need to continue progress toward state goals for offshore wind generation. The NYSPSC is expected to decide whether to continue with the NYC PPTN in the spring of 2025. Concurrently, the NYISO will identify, evaluate, and report on the top-tier projects by Q2 2025 with the timeline for the NYISO Board selection of a project by Q2-Q3 2025. NYSPSC Operations Audit for NY State Utilities • In February 2025, the NYSPSC issued an order(d) directing the New York State Department of Public Service to conduct a state-wide audit on the design of New York state utilities' non-executive incentive compensation programs, including CECONY and O&R. The audit is expected to begin in June or July 2025 with a report due mid-2026. The NYSPSC periodically audits CECONY and O&R and their respective operations.

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. 19

(page 45) In April 2025, CECONY filed an update to its January 2025 request to the New York State Public Service Commission (NYSPSC) for an electric rate increase effective January 1, 2026. The company decreased its requested January 2026 rate increase by $3 million to $1,608 million, increased its illustrative January 2027 rate increase by $5 million to $937 million and decreased its illustrative January 2028 rate increase by $9 million to $871 million. The filing reflects a rate on common equity of 10 percent and a common equity ratio of 48 percent. (page 21) In April 2025, CECONY filed an update to its January 2025 request to the NYSPSC for a gas rate increase effective January 1, 2026. The company decreased its requested January 2026 rate increase by $91 million to $349 million, increased its illustrative January 2027 rate increase by $3 million to $269 million and increased its illustrative January 2028 rate increase by $9 million to $174 million. The filing reflects a rate on common equity of 10 percent and a common equity ratio of 48 percent. (page 21) In April 2025, construction of relevant marine activities associated with Empire Wind 1 offshore wind project (810 MW) were suspended in compliance with a stop work order issued by the United States Bureau of Ocean Energy Management. See "Federal Regulation," above. The project was expected to enter commercial operation in 2027 and connect to the New York City electrical grid at CECONY’s Gowanus substation.
