Outlook and guidance

• Plant consolidation and overhead reductions target $85M-$115M in adjusted EBITDA improvement at full run rate; utilization is expected to reach ~80%, with minimal change to annual volumes.

• Implementation costs are expected at $40M-$60M over 18 months; corporate and operations workforce is expected to decline ~20%, and working-capital needs are expected to fall as the footprint is consolidated.

• Q4 is expected to remain challenging due to energy costs and weak European ferrosilicon markets; CapEx is expected to decline significantly.

• Silicon metal outlook is improving as 2027 negotiations begin; silicon-based alloys remain positive in the U.S. but face excess supply in Europe. Manganese-alloy volumes are expected to remain solid in Q4.

• Additional ferromolybdenum shipments and initial ferrovanadium and ferrochromium shipments are expected in Q4, following production validation.
