According to the Birmingham News, the former office has now been closed. The new home base in the Galleria Tower employs 100 people, and about 20 relocated from Florida to Alabama with the company.

The move took some time to make; while Walter officials first announced intent to relocate the headquarters over a year ago, it changed target locations in Alabama’s largest city after acquiring Canadian producer Western Coal in a $US3.3 billion deal – a move which added operations in the UK, Canada and West Virginia to its portfolio.

Walter Energy is the second US producer to call Alabama home, as Drummond Coal is already headquartered in the state.

The Birmingham News also said that Walter will become the fifth-largest publicly-traded Birmingham-based company, with revenue of $1.6 billion last year. While some of the company’s executives will remain in Vancouver at the former Western Coal offices, others will continue to split their time between Canada and Birmingham.
