2 Forward Looking Statements This presentation contains forward-looking statements within the meaning of the securities laws. Forward-looking statements can be identified by the fact that they do not relate strictly to historical or current facts. They often include words or variation of words such as "expects," "anticipates," "intends," "plans," "believes," "seeks," "estimates," "projects," "forecasts," "targets," "would," "will," "should," "goal," "could" or "may" or other similar expressions. 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 the Company’s operating plans, market conditions for the Company’s products, reclamation obligations, financial outlook, potential acquisitions and strategic investments, the development of the Company’s rare earth elements and critical minerals program, and liquidity requirements. 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, 2025, 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.

33 Centurion Royalties • Centurion is subject to the Queensland Government Royalty charged on total revenue. Queensland Government royalties are based on coal prices per tonne (in $A). • Centurion South is subject to a special private royalty agreement established in relation to the sale of the property by a prior owner. This special royalty is limited to production from the Goonyella Middle Seam (GMS) within a defined area. The royalty, paid annually, amounts to 20% of the nominal before-tax cashflow attributable to sales from the defined area less capex, and any accumulated losses (since the original sale process was completed in CY2000). • Centurion North (Wards Well) tenements, is subject to a price-linked royalty payable to the prior owner on the first 120Mt of product coal mined from the area, capped at US$200M. Peabody will only commence making payments once it has recovered its upfront investment in the development of Centurion North. • All royalties have been considered in the financial analysis.

38 Reconciliation of Non-GAAP Measures Note: Management believes that non-GAAP financial 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. Note: Certain forward-looking measures and metrics presented are non-GAAP financial and operating/statistical measures. Due to the volatility and variability of certain items needed to reconcile these measures to their nearest GAAP measure, no reconciliation can be provided without unreasonable cost or effort. (1) Total Segment Costs, which is a non-GAAP financial measure, is defined as operating costs and expenses adjusted for the discrete items that management excluded in analyzing each reportable segment's operating performance as displayed in the reconciliation above. Total Segment Costs is used by management as a component of a metric to measure each segment's operating performance. (2) Adjusted EBITDA, which is a non-GAAP financial measure, is defined as (loss) 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 the reportable segments' operating performance as displayed in the reconciliation above. Adjusted EBITDA is used by the chief operating decision maker as the primary financial metric to measure each segment's operating performance against expected results and to allocate resources, including capital investment in mining operations and potential expansions. (3) Includes gains (losses) on certain surplus coal reserve, coal resource and surface land sales and property management costs and revenue. (4) Includes trading and brokerage activities; costs associated with post-mining activities; gains (losses) on certain asset disposals; minimum charges on certain transportation-related contracts; results from the Company's other equity method investments; costs associated with suspended operations; holding costs associated with the Centurion Mine; the impact of foreign currency remeasurement; expenses related to our other commercial activities; revenue of $25.9 million related to the assignment of port and rail capacity during 2023; and a gain of $26.1 million recognized on the sale of the Millennium Mine during 2021. (5) EBITDA Margin per Ton refers to Adjusted EBITDA Margin per Ton which is an operating/statistical measure equal to Adjusted EBITDA by segment divided by segment tons sold. Management believes Adjusted EBITDA Margin per Ton best reflects controllable costs and operating results at the reporting segment level. (6) Costs refers to Costs per Ton which is an operating/statistical measure equal to Revenue per Ton (which is equal to revenue by segment divided by segment tons sold) less Adjusted EBITDA Margin per Ton. Management believes Costs per Ton best reflects controllable costs and operating results at the reporting segment level. (7) Adjusted EBITDA Margin is an operating/statistical measure equal to segment Adjusted EBITDA divided by segment revenue. Management believes Adjusted EBITDA Margin best reflects operating results at the reporting segment level.
