PEABODY REPORTS RESULTS FOR FOURTH QUARTER AND YEAR ENDED DECEMBER 31, 2022

Reports Record Earnings; Retires All Senior Secured Debt

Generates Fourth Quarter Operating Cash Flow of $670 million and Record Free Cash Flow1 of $580 million

ST. LOUIS, Feb. 14, 2023 – Peabody (NYSE: BTU) today reported fourth quarter net income attributable to common stockholders of $632.0 million, or $3.92 per diluted share, compared to $513.0 million, or $3.93 per diluted share, in the prior year quarter. Peabody’s fourth quarter 2022 results included a $199.3 million unrealized mark-to-market gain related to its coal hedging activities. Peabody had Adjusted EBITDA1 of $500.5 million in the fourth quarter of 2022 compared to $444.4 million in the fourth quarter of 2021.

Full-year 2022 revenue totaled $4,981.9 million compared to $3,318.3 million in the prior year. Full-year 2022 net income attributable to common stockholders totaled $1,297.1 million, or $8.31 per diluted share, compared to $360.1 million, or $3.22 per diluted share in the prior year. Adjusted EBITDA was $1,844.7 million, more than two times the prior year result of $916.7 million. Peabody generated cash flows from operating activities of $1,173.6 million resulting in Free Cash Flow of $1,144.9 million for the full year, compared to cash flows from operating activities of $420.0 million and Free Cash Flow of $288.5 million in the prior year.

“Our remarkable fourth quarter results demonstrated the value of Peabody’s diverse asset portfolio. While there were challenges to overcome, we were able to deliver record Free Cash Flow and repay all remaining senior secured debt,” said Peabody President and Chief Executive Officer Jim Grech. “Additionally, due to our strong operating results and financial condition, we are actively addressing the remaining requirements to implement a shareholder return program.”

Fourth Quarter and Full Year Highlights

•Retired all senior secured debt

•Record Free Cash Flow of $580 million in the fourth quarter

•Adjusted EBITDA of $501 million in the fourth quarter and $1,845 million for the full year 2022

•Record full year net income attributable to common stockholders of $1,297 million and Diluted EPS of $8.31

•Achieved highest 2022 quarterly production rate in three out of four operating segments in the fourth quarter

•Record low annual global injury rate, with zero reportable incidents at three of our mines

1 Adjusted EBITDA and Free Cash Flow are non-GAAP financial measures. Adjusted EBITDA margin is equal to segment Adjusted EBITDA divided by segment revenue. Revenue per Ton and Adjusted EBITDA Margin per Ton are equal to revenue by segment and Adjusted EBITDA by segment, respectively, divided by segment tons sold. Costs per Ton is equal to Revenue per Ton less Adjusted EBITDA Margin per Ton. Management believes Costs per Ton and Adjusted EBITDA Margin per Ton best reflect controllable costs and operating results at the reporting segment level. We consider all measures reported on a per ton basis, as well as Adjusted EBITDA margin, to be operating/statistical measures. Please refer to the tables and related notes in this press release for a reconciliation and definition of non-GAAP financial measures.

During the fourth quarter, the seaborne thermal segment shipped 4.1 million tons, the highest quarterly sales volume for the year, 0.4 million tons more than the third quarter. Export shipments increased by approximately 0.7 million tons in the quarter to 2.3 million tons. The average export realized price decreased 19 percent to $151.61 per ton, primarily due to higher hedged ton settlements compared to the prior quarter. Fourth quarter seaborne thermal segment costs decreased 12 percent to $43.10 per ton due to lower sales price-sensitive costs and favorable production volumes, despite rainfall which was 40 percent higher than the historical average. The segment reported Adjusted EBITDA margins of 54 percent and Adjusted EBITDA of $209.1 million in the fourth quarter.

The PRB segment shipped 21.2 million tons at an average realized price of $13.88 per ton in the fourth quarter, $0.89 per ton higher than the prior quarter. Tons sold were negatively impacted by approximately 1.1 million tons, primarily due to winter weather related rail disruptions. PRB costs per ton increased 13 percent, or $1.42 per ton, primarily due to lower sales volumes, higher black lung excise taxes as part of the Inflation Reduction Act and higher maintenance and repair costs. The segment reported 8 percent Adjusted EBITDA margins and Adjusted EBITDA of $24.7 million in the fourth quarter.

First Quarter 2023 Outlook

Seaborne Thermal

•Export volume is expected to be 1.8 million tons, less than ratable to full-year guidance, due to lower production as a result of a longwall move at Wambo Underground and recovery from heavy rains in the fourth quarter.

•0.7 million export tons are priced at $189 per ton (includes the Wambo hedges at $84 per metric tonne), and approximately 0.9 million tons of high ash product and 0.2 million tons of Newcastle product are unpriced.

•Costs are expected to be $60-$65 per ton.

Seaborne Metallurgical

•Seaborne met volumes are expected to be 1.3-1.5 million tons, less than ratable to full-year guidance due to heavy rains in Queensland and geologic conditions at Shoal Creek.

•0.9 million export tons are priced at $216 per ton. The remaining unpriced volumes are expected to achieve 75 to 80 percent of the premium hard coking coal price index.

•Costs are expected to be $140-$150 per ton.

U.S. Thermal

•PRB volume is expected to be approximately 22 million tons at an average price of $13.80 per ton and cost of approximately $11.60 per ton.

•Other U.S. Thermal volume is expected to be approximately 4.7 million tons at an average price of $52.50 per ton and cost of approximately $40 per ton.

Forward-Looking Statements

This press release 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 current expectations or predictions of future conditions, events or results. All statements that address operating performance, events, or developments that Peabody expects will occur in the future are forward-looking statements. 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, including the impact of the COVID-19 pandemic and factors that are described in Peabody’s Annual Report on Form 10-K for the fiscal year ended Dec. 31, 2021, 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.
