Digging into the deets of the new deal

In an effort to expedite the development of the domestic end-to-end rare earth magnet supply chain -- and shore up the nation's security by reducing its dependence on China and others for rare earths -- the Department of Defense has entered into a public-private partnership with MP Materials.

The Department of Defense is providing "a multibillion-dollar package of investments and long-term commitments" that will assist the company in developing a second magnet manufacturing facility in the U.S.

According to the agreement, the Department of Defense will purchase $400 million of a newly created series of preferred stock that's convertible into shares of the MP Materials common stock as well as a warrant permitting the Department of Defense to acquire additional shares of common stock.

As a result of the agreement, the Department of Defense is poised to become the largest shareholder of MP Materials stock.

Should potential investors follow Uncle Sam's lead?

The new deal with the Department of Defense may very well turn out to be transformational for MP Materials, and the market's enthusiasm is understandable. With the stock's impressive rise since the start of the year, however, those looking to load up on the mining stock may want to wait for a pullback as the market's exuberance tapers off.
