MP Materials stock pops as William Blair starts coverage and rare-earth price floors hit the agenda again
Shares of MP Materials surged 7.5% Wednesday, closing at $68.63 after swinging between $62.20 and $68.73. The move followed William Blair’s new coverage and G7 talks on rare-earth price floors. MP’s recent filings show a $400 million Pentagon deal with a 10-year price floor for neodymium-praseodymium. Apple signed a $500 million rare-earth magnet contract with MP last year.
