INTERNAL Available Information This presentation should be read together with, and is qualified in its entirety by reference to, the company’s most recent filings with the Securities and Exchange Commission and are available at: www.conedison.com/ en/. (Select “For Investors” and then select “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.

INTERNAL Revised CECONY and O&R Average Investment Earnings Base(a)(b)(c)(d) 8 Reflects CECONY Electric and Gas joint proposal and shift of certain investments to surcharge. In February 2026, Con Edison will update its forecast through 2030 Surcharge recovery programs (not in base rates) are primarily comprised of Transportation Electrification (Electric Vehicles Make Ready Program), Utility Thermal Energy Networks, and Utility Storage Dispatch Rights, Energy Efficiency and Heat Pump programs (formerly known as New Efficiency New York), and capital investments associated with those programs. a. Excludes the Utilities' average interest bearing Construction Work In Progress. b. Forecast for 2026, 2027 and 2028 reflects CECONY’s November 2025 joint proposal for new electric and gas rate plans (Case 25-E-0072 & 25-G-0073) that is subject to approval by the NYSPSC. c. Forecast for 2025, 2026 and 2027 reflects O&R’s Electric and Gas rate plans (Case 24-E-0060 & 24-G-0061) approved in March 2025. d. Amounts for energy efficiency and heat pump program activity are included in the average rate base forecast for CECONY and O&R in 2025, and for O&R for the years 2026 – 2028. Amounts for New Efficiency New York are included in the surcharge recovery forecast for CECONY for the years 2026 - 2028 to reflect the November 2025 CECONY electric and gas joint proposal. In May 2025, the NYSPSC issued two orders for Low- to Moderate- Income and Non-Low- to Moderate-Income that directed CECONY and O&R to recover 2026-2028 energy efficiency and heat pump program activity through surcharge rather than base rates. In February 2026, Con Edison will update its forecast through 2030. ($ in millions) Prior Plan - Reflects CECONY’s April 2025 updated electric and gas rate filings Revised Plan - Reflects CECONY’s November 2025 joint proposal for new electric and gas rate plans Differences between prior plan and revised plan are 1.95%, 3.10%, and 3.87% for years 2026, 2027 and 2028 respectively
