5N Plus plans to expand its St. George, Utah facility by approximately 50%, with completion targeted for H2 2027. The site transforms indium antimonide and other specialty materials into semiconductor materials, wafers, substrates and selected components, with recovery, purification and crystal-growth capabilities. New equipment will be installed progressively, but InSb-specific capacity was not disclosed; the 50% figure refers to the facility expansion, not indium demand.
