MP Materials Corp. (NYSE:MP)
MP Materials dropped its share prices by 11.99 percent on Monday to close at $23.19 apiece following news last week that it had halted shipments of rare earth materials to China amid the latter’s retaliatory tariffs and export controls.
“Selling our valuable critical materials under 125 percent tariffs is neither commercially rational nor aligned with America’s national interest,” MP said in a statement last week.
“We have been preparing for this moment since day one. Our mission, capital strategy, and execution reflect a long-term vision built to withstand short-term dislocation and emerge stronger,” it added.
MP said it invested nearly $1 billion to restore the full rare earth supply chain in the US, and that its California refinery is processing nearly half of its total production. Virtually all materials are sold into markets outside China, such as Japan, South Korea, and the US.
MP produces rare earth materials, a group of 17 metals used to make magnets that turn power into motion for electric vehicles, cell phones, and other electronics. The company is currently one of the largest non-Chinese rare earth miners and processors globally.
