CON EDISON REPORTS 2024 THIRD QUARTER EARNINGS

NEW YORK - Consolidated Edison, Inc. (Con Edison) (NYSE: ED) today reported 2024 third quarter net income for common stock of $588 million or $1.70 a share compared with $526 million or $1.53 a share in the 2023 third quarter. Adjusted earnings (non-GAAP) were $583 million or $1.68 a share in the 2024 period compared with $561 million or $1.62 a share in the 2023 period. Adjusted earnings and adjusted earnings per share in the 2024 and 2023 periods exclude the effects of hypothetical liquidation at book value (HLBV) accounting for tax equity investments. Adjusted earnings and adjusted earnings per share in the 2024 period exclude accretion of the basis difference of Con Edison's equity investment in Mountain Valley Pipeline, LLC (MVP) and in the 2023 period exclude adjustments to the gain and other impacts related to the sale of all of the stock of Con Edison's former subsidiary, Con Edison Clean Energy Businesses, Inc. (the Clean Energy Businesses) in 2023.

For the first nine months of 2024, net income for common stock was $1,510 million or $4.37 a share compared with $2,185 million or $6.27 a share in the first nine months of 2023. Adjusted earnings were $1,528 million or $4.42 a share in the 2024 period compared with $1,416 million or $4.07 a share in the 2023 period. Adjusted earnings and adjusted earnings per share in the 2024 period exclude accretion of the basis difference of Con Edison's equity investment in MVP. Adjusted earnings and adjusted earnings per share in the 2024 and 2023 periods exclude the effects of HLBV accounting for tax equity investments and adjustments to the gain and other impacts related to the sale of all of the stock of the Clean Energy Businesses in 2023. Adjusted earnings and adjusted earnings per share in the 2023 period exclude the net mark-to-market effects of the Clean Energy Businesses.

“Core to our growth strategy is our continued investment in clean energy infrastructure and energy-efficient solutions for our customers,” said Tim Cawley, the chairman and CEO of Con Edison. “Our programs eased electric demand during another hot New York summer, helping us keep the power flowing for our customers. As New Yorkers transition to electrification of building space heating and transportation, we’ve made it easier to install EV chargers and continue to provide incentives for heat pump installation. We have delivered infrastructure investments to build the grid of the future while providing industry-leading reliability to millions of customers.”

“As a result of our solid third quarter results and financial performance year to date as well as our outlook for the balance of the year, we are narrowing and revising our 2024 adjusted EPS guidance to the upper half of our original range,” said Kirk Andrews, senior vice president and CFO of Con Edison. “We continue to expect solid rate base growth as we continue to make investments to both enable New York's clean energy transition and upgrade our infrastructure to improve its resilience in the face of climate change.”

For the year of 2024, Con Edison expects its adjusted earnings per share to be in the range of $5.30 to $5.40 per share. Con Edison's previous forecast was in the range of $5.20 to $5.40 per share. Adjusted earnings per share exclude the effects of HLBV accounting for tax equity investments (approximately $0.01 a share after-tax), accretion of the basis difference of Con Edison's equity investment in MVP (approximately $(0.01) a share after-tax) and adjustments to the gain and other impacts related to the sale of all of the stock of the Clean Energy Businesses in 2023, the amount of which will not be determinable until year-end.

See Attachment A to this press release for a reconciliation of Con Edison’s reported earnings per share to adjusted earnings per share and reported net income for common stock to adjusted earnings for the three and nine months ended September 30, 2024 and 2023. See Attachments B and C for the estimated effect of major factors resulting in variations in earnings per share and net income for common stock for the three and nine months ended September 30, 2024 compared to the 2023 periods.

The company's 2024 Third Quarter Form 10-Q is being filed with the Securities and Exchange Commission. A third quarter 2024 earnings release presentation will be available at www.conedison.com. (Select "For Investors" and then select "Press Releases.")

CON EDISON REPORTS 2024 THIRD QUARTER EARNINGS page 2

This press release 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 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.

This press release also contains financial measures, adjusted earnings and adjusted earnings per share, 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 the gain and other impacts related to the sale of all of the stock of the Clean Energy Businesses, the effects of HLBV accounting for tax equity investments, mark-to-market accounting and accretion of the basis difference of Con Edison's equity investment in 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.
