2 8 Key Macro Tailwinds and Assets

9 Peabody Sits at the Intersection of Powerful Macro Trends Record Global Coal Demand Global coal use keeps setting all-time records — more than 1,200 GW of new coal capacity is in development or construction, led by Asia. U.S. Power Load Surging AI and data centers are driving the first sustained U.S. load growth in decades — projected ~27% higher from 2020 to 2035. Indian Steel Production Rising India has overtaken China as the world's largest seaborne metallurgical- coal importer as blast-furnace capacity rapidly expands. Tailwinds across global coal, U.S. power demand and Asian steel Sources: S&P Global Energy; IEA; Energy Ventures Analysis; Peabody analysis.

10 Coal anchors energy security NO WARS ARE FOUGHT OVER COAL Abundant and widely distributed across many suppliers and insulated from the chokepoints that disrupt oil and gas. CONFLICT RENEWS THE RELIABILITY CASE Coal dispatches on command and stockpiles on site. The exact margin reliability-focused buyers rediscover in every crisis. SEABORNE SUPPLY IS TIGHTENING Indonesian export curbs, a decade of underinvestment in new capacity and declining quality at aging mines are constraining seaborne thermal supply. STRUCTURAL ASIAN RELIANCE Asia keeps building coal capacity at scale, anchoring durable long-term thermal demand. Sources: S&P Global; IEA; Peabody analysis.

Refer to the definitions and reconciliations to the nearest GAAP measures in the appendix. Mine disruptions and elevated LNG prices tighten the market into winter restocking MARKET DRIVERS FY26 OUTLOOK VOLATILITY FACTORS • Extended Middle East conflict supports elevated LNG pricing and coal competitiveness in Asia. • Higher oil prices have increased ocean freight costs, improving Australia’s competitiveness as a shorter-haul coal supplier to Asia. • El Niño-driven drought conditions could constrain Indonesian coal exports and reduce regional hydro generation, supporting Australian thermal coal demand.

Cost/Ton2 Domestic 4.5 $34.00 $49.50- $54.50Export 7.9-8.5 $91.20 • European storage levels may drive pre- winter LNG buying, increasing competition with Asia for LNG cargoes and supporting seaborne thermal coal prices. • Chinese supply remains constrained following recent safety incidents, effecting upcoming winter restocking driving higher imports. • Global diesel supply disruptions could restrict coal production and logistics, especially Russian exports. • Indonesian production and export policy uncertainty supports higher coal prices.

14 Growing Low-Cost Export Tons into Asian Demand Wilpinjong export-priced volumes expected to more than double by 2030 PLANNED WILPINJONG EXPORT VOLUMES • Wilpinjong export priced tons are expected to more than double by 2030. • Pits 9 & 10 extend mine life to 2038; environmental studies and approvals are progressing. • New pits expected to further improve cost structure and productivity at one of Australia’s lowest-cost mines. W H Y I T M AT T E R S : NEWC6000 and API5 compete with LNG (JKM) for the same Asian power demand. When LNG spikes – Ukraine, the Middle East – it sends buyers back to coal. Two LNG crises in four years have driven fuel switching to coal and reinforced its role as reliable baseload. Note: Adjusted EBITDA is a non-GAAP financial measure.

39 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) Available Free Cash Flow, which is a non-GAAP financial measure, is defined as operating cash flow less investing cash flow and distributions to noncontrolling interests, plus/minus changes to restricted cash and collateral and other anticipated expenditures. Available Free Cash Flow is used by management as a measure of our ability to generate excess cash flow from our business operations. 6) This amount is equal to the total change in Restricted Cash and Collateral on the balance sheet, excluding partially offsetting amounts included in operating cash flow consisting of an inflow of $75.8 million for the six months ended June 30, 2026. 7) Adjusted EBITDA Margin per Ton 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. 8) Costs per Ton 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. 9) 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.
