Apple Inc. has secured a $500 million agreement to purchase rare earth minerals from U.S. supplier MP Materials, which recently received investment from the Pentagon.

In a Tuesday announcement, Apple disclosed plans for a joint manufacturing facility in Texas dedicated to producing neodymium magnets exclusively for Apple devices. The tech giant emphasized this procurement aligns with its $500 billion U.S. investment pledge spanning the next four years.

Market reaction diverged sharply: MP Materials shares jumped 9% in pre-market trading while Apple's stock showed minimal movement, holding steady amid the supply-chain development.
