Forward-looking statements provide management's or the Board’s current expectations or predictions of future conditions, events or results. All statements that address operating performance, events, or developments that may occur in the future are forward-looking statements, including statements regarding the shareholder return framework, execution of Peabody's operating plans, market conditions, reclamation obligations, financial outlook, potential acquisitions and strategic investments, and liquidity requirements. They may include estimates of sales and other operating performance targets, cost savings, capital expenditures, other expense items, actions relating to strategic initiatives, demand for the company’s products, liquidity, capital structure, market share, industry volume, other financial items, descriptions of management’s plans or objectives for future operations and descriptions of assumptions underlying any of the above. All forward-looking statements speak only as of the date they are made and reflect Peabody’s good faith beliefs, assumptions and expectations, but they are not guarantees of future performance or events. Furthermore, Peabody disclaims any obligation to publicly update or revise any forward-looking statement, except as required by law. By their nature, forward-looking statements are subject to risks and uncertainties that could cause actual results to differ materially from those suggested by the forward-looking statements. Factors that might cause such differences include, but are not limited to, a variety of economic, competitive, and regulatory factors, many of which are beyond Peabody's control, that are described in Peabody's periodic reports filed with the SEC including its Annual Report on Form 10-K for the fiscal year ended Dec. 31, 2023 and other factors that Peabody may describe from time to time in other filings with the SEC. You may get such filings for free at Peabody's website at www.peabodyenergy.com. You should understand that it is not possible to predict or identify all such factors and, consequently, you should not consider any such list to be a complete set of all potential risks or uncertainties.

22 MISO SPP ERCOT PJM U.S. Electricity Generation Mix Remains Very Reliant on Coal Generation Source: Graph based on EIA, S&P Capital IQ, ISOs and Peabody analysis (1/01/2023 – 2/12/2024). Each dataset is represented by a boxed area where the central line signifies the median (P50) value, the bottom edge represents the 25th percentile, and the top edge represents the 75th percentile. Between the two extreme "whiskers" of each dataset, more than 90% of the data is encompassed. • Difficult to match reliability characteristics of coal generation • High coal share when renewables are not dispatching • MISO and SPP continue to rely heavily on coal to meet power demand • ~60% of Peabody’s U.S. thermal coal shipped to utilities goes to MISO and SPP plants • Hourly data for the past 12 months shows significant regional differences in coal’s contribution to the generation mix Hourly Coal Generation Share

23 Proposed EPA Regulations • In April, the EPA released its Clean Power Plan 2.0 which will accelerate the retirement of well- functioning coal plants necessary for baseload power across the country • Taking into account announced coal retirements, more than 100,000 MW of coal-fired generation are at risk of premature retirement because of these new policies 1 • 23 states and the National Rural Electric Cooperative Association filed lawsuits for review of the EPA regulations Source: “America’s Power Stresses Importance of Dispatchable Resources” - America's Power (americaspower.org)

41 Reconciliation of Non-GAAP Measures: Definitions (1) (2) (3) (4) (5) (6) (7) Note: Management believes that non-GAAP performance measures are used by investors to measure our operating performance. These measures are not intended to serve as alternatives to U.S. GAAP measures of performance and may not be comparable to similarly-titled measures presented by other companies. Total Reporting Segment Costs is defined as operating costs and expenses adjusted for the discrete items that management excluded in analyzing each of our segment's operating performance as displayed in the reconciliation above. Total Reporting Segment Costs is used by management as a component of a metric to measure each of our segment's operating performance. Adjusted EBITDA is defined as income from continuing operations before deducting net interest expense, income taxes, asset retirement obligation expenses and depreciation, depletion and amortization. Adjusted EBITDA is also adjusted for the discrete items that management excluded in analyzing each of our segment's operating performance as displayed in the reconciliation above. Adjusted EBITDA is used by management as the primary metric to measure each of our segment's operating performance and allocate resources. Includes gains (losses) on certain surplus coal reserve and surface land sales and property management costs and revenue. Includes trading and brokerage activities; costs associated with post-mining activities; gains (losses) on certain asset disposals; minimum charges on certain transportation-related contracts; costs associated with suspended operations including the Centurion Mine; a gain of $26.1 mill ion recognized on the sale of the Millennium Mine during 2021; and revenue of $25.9 mill ion related to the assignment of port and rail capacity during 2023. Free Cash Flow is defined as net cash provided by operating activities less net cash used in investing activities and excludes cash outflows related to business combinations. Free Cash Flow is used by management as a measure of our ability to generate excess cash flow from our business operations. Segment Free Cash Flow is equal to Segment Adjusted EBITDA less Segment additions to property, plant, equipment and mine development. Segment Free Cash Flow is used by management as a measure of our ability to generate excess cash flow from our business operations. Adjusted Capital Expenditures is equal to Segment additions to property, plant, equipment and mine development less additions for certain capitalized components. Adjusted Capital Expenditures is used by management as a measure of our capital spending in comparison to others within the coal industry.
