1. High debt burden - Peabody Energy Corporation has a significant amount of debt, which can limit its financial flexibility and increase its vulnerability to economic downturns or changes in the industry.

2. Declining demand for coal - The company's primary focus is on coal mining, which is facing a decline in demand due to increasing environmental concerns and the shift towards cleaner energy sources. This can negatively impact Peabody Energy's long-term growth prospects.

3. Environmental and regulatory challenges - As a coal mining company, Peabody Energy faces increasing scrutiny and regulatory challenges related to environmental impact, carbon emissions, and compliance with stricter regulations. This can result in additional costs and potential reputational damage.

4. Limited diversification - Peabody Energy's business is heavily reliant on coal mining, which makes it vulnerable to fluctuations in coal prices and demand. Lack of diversification into other energy sources or commodities can limit the company's ability to adapt to changing market conditions.

5. Potential legal liabilities - The coal industry has faced numerous lawsuits related to health and environmental impacts. Peabody Energy may be exposed to legal liabilities, such as claims related to worker safety, environmental damage, or health issues, which can result in significant financial costs.

6. Competitive landscape - Peabody Energy operates in a highly competitive industry, facing competition from both domestic and international coal producers. Intense competition can lead to pricing pressures, reduced market share, and lower profitability for the company.
