Arch Resources, Inc., formerly known as Arch Coal, is a leading producer of metallurgical and thermal coal in the United States. The company operates mines across major coal-producing regions, including the Powder River Basin in Wyoming and the Appalachian region in West Virginia, Kentucky, and Virginia. Arch Resources was founded in 1969 as a division of Ashland Oil and became an independent company in 1997.

In 2005, it acquired Triton Coal Company, expanding its presence in the western United States. The company underwent a major restructuring in 2016 to navigate challenging market conditions, including filing for Chapter 11 bankruptcy and reemerging as a leaner, more focused organization. The company's headquarters is located in St.

Louis, Missouri. The modern and environmentally friendly office space provides a collaborative work environment for employees. The headquarters also houses various departments, including finance, legal, marketing, and human resources.

Arch Resources specializes in producing coal used in steel production (metallurgical or coking coal) as well as coal used for generating electricity (thermal coal). The company operates a diversified portfolio of mines to cater to different market segments and customers' needs. On a global scale, Arch Resources primarily focuses on domestic coal production and sales.

However, the company has a subsidiary called Arch Energy Resources that engages in coal trading and marketing worldwide. This subsidiary helps Arch Resources expand its global reach and access international markets. Arch Resources faces competitive challenges from both domestic and international coal producers.

In the United States, it competes with companies like Peabody Energy and Consol Energy. Globally, competition comes from large coal producers in Australia, Indonesia, and Russia. In recent years, Arch Resources has made significant strides in reducing its environmental impact and transitioning toward cleaner and more sustainable energy sources.

The company has embraced renewable energy initiatives and technologies, focusing on reducing greenhouse gas emissions and supporting reclamation and land restoration efforts. As of the latest available information, Arch Resources continues to be an influential player in the coal industry, contributing significantly to the domestic and global coal markets. The company is committed to meeting the demand for coal while adapting to changing industry dynamics and pursuing sustainable practices
