REMX is trading 3.3% up in pre-market on August 21, 2026, as rare-earth prices strengthen.

• Pr-Nd oxide prices rose by 8,000 yuan/mt, while dysprosium and terbium oxide prices also advanced.
• The moves signal tighter supply and stronger pricing across key materials.
• Concern over China’s rare-earth export controls and falling shipments is reinforcing scarcity expectations for non-Chinese supply; broader futures are modestly higher, but the sector-specific catalyst appears more important.
