Bank of America- Merrill Lynch Global Metals and Mining Conference Gregory H. Boyce Chairman and Chief Executive Officer May 11-12, 2011 Exhibit 99.1

2 Some of the following information contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, as amended, and is intended to come within the safe-harbor protection provided by those sections. Our forward-looking statements are based on numerous assumptions that the company believes are reasonable, but they are open to a wide range of uncertainties and business risks that may cause actual results to differ materially from expectations as of Apr. 19, 2011. These factors are difficult to accurately predict and may be beyond the company's control. The company does not undertake to update its forward-looking statements. Factors that could affect the company's results include, but are not limited to: demand for coal in the United States and the seaborne thermal and metallurgical coal markets; price volatility and demand, particularly in higher-margin products and in our trading and brokerage businesses; impact of weather on demand, production and transportation; reductions and/or deferrals of purchases by major customers and ability to renew sales contracts; credit and performance risks associated with customers, suppliers, co-shippers, trading, banks and other financial counterparties; geologic, equipment, permitting and operational risks related to mining; transportation availability, performance and costs; availability, timing of delivery and costs of key supplies, capital equipment or commodities such as diesel fuel, steel, explosives and tires; successful implementation of business strategies, including our Btu Conversion and generation development initiatives; negotiation of labor contracts, employee relations and workforce availability; changes in postretirement benefit and pension obligations and funding requirements; replacement and development of coal reserves; availability, access to and the related cost of capital and financial markets; effects of changes in interest rates and currency exchange rates (primarily the Australian dollar); effects of acquisitions or divestitures; economic strength and political stability of countries in which we have operations or serve customers; legislation, regulations and court decisions or other government actions, including new environmental requirements, changes in income tax regulations or other regulatory taxes; litigation, including claims not yet asserted; and other risks detailed in the company's reports filed with the Securities and Exchange Commission (SEC). The use of "Peabody," "the company," and "our" relate to Peabody, its subsidiaries and majority-owned affiliates. EBITDA or Adjusted EBITDA is defined as income from continuing operations before deducting net interest expense, income taxes, asset retirement obligation expense, and depreciation, depletion and amortization. EBITDA, which is not calculated identically by all companies, is not a substitute for operating income, net income or cash flow as determined in accordance with United States generally accepted accounting principles. Management uses EBITDA as a key measure of operating performance and also believes it is a useful indicator of the company's ability to meet debt service and capital expenditure requirements. Adjusted EPS is defined as income from continuing operations and diluted earnings per share excluding the impact of the remeasurement of foreign income tax accounts. Management has included this measurement because, in management's opinion, excluding such impact is a better indicator of the company's ongoing effective tax rate and diluted earnings per share, and is therefore more useful in comparing the company's results with prior and future periods. 04/19/11 Statement on Forward-Looking Information
