Based on my analysis of recent data, Peabody Energy's stock rally is driven by several significant factors:
Key Rally Drivers:
1. Strong US Thermal Coal Market Performance
US coal-fueled generation is up 15% in the first half of 2025 compared to 2024, driven by coal increasing market share due to high natural gas prices and growing electricity demand from industrial activity and data centers. [

2. Major Legislative Tailwinds - "One Big Beautiful Bill"
The bill reduces federal royalty rates on mining leases from 12.5% to 7%, expected to generate $15-20 million in net benefits for Peabody in 2025 alone, improving PRB competitiveness. It also provides a 2.5% production tax credit for domestic coal used in steelmaking, benefiting Peabody's Shoal Creek mine. [

3. Raised Full-Year Guidance
The company raised PRB volumes by 5 million tons and lowered full-year costs by $0.63 to $11.50-$12. Seaborne thermal volumes increased by 200,000 tons with costs improved by $3/ton. CapEx was reduced by $30 million to $420 million. [

4. Centurion Mine Development Accelerated
Peabody accelerated longwall operations at its flagship premium hard coking coal mine, Centurion, now targeting longwall start-up in February 2026 (pulled forward from Q1). The company plans to install longwall shields in November with workforce expansion to ~400 employees by early 2026. [

5. Excellent Cost Control
Despite challenging seaborne pricing, three of four segments beat cost targets. The US thermal platform generated $57 million of adjusted EBITDA with the PRB improving margins by over $1/ton year-over-year. [

6. Growing Electricity Demand from Data Centers
One independent system operator forecasted a 32 gigawatt increase in power demand by 2030, with 30 gigawatts related to data centers - comparable to adding 20 million new homes to the grid in five years. [

Financial Performance:
For Q2 2025, Peabody generated $890.1 million in revenue and $93.3 million in adjusted EBITDA. For the first half of 2025, revenue was $1.83 billion with adjusted EBITDA of $237.3 million. [

The combination of supportive US policy, strong domestic coal demand, operational excellence, and the Centurion development timeline has created significant positive momentum for the stock.
