US: USG plans to mothball its Southard gypsum processing plant and mine and processing plant in Blaine County, Oklahoma, in November 2026. The move is a response to ‘escalating’ complexity and costs impacting ‘specialised’ product lines. USG reportedly plans to phase out ‘a majority of products’ produced at the plant from its portfolio following the closure. Local press has reported that USG employs 300 people across Oklahoma.
USG told Southard plant and mine workers that "We are committed to supporting impacted team members by providing career transition resources, relocation opportunities for those interested in transferring to another USG facility and severance packages for affected employees."
