MP Materials Begins Construction on Texas Rare Earth Magnetics Factory to Restore Full U.S. Supply Chain

• MP Materials and General Motors simultaneously announce a definitive supply agreement commencing in late 2023 to produce rare earth alloy and magnets for GM’s EV programs

• The facility will create approximately 150 skilled jobs and approximately 1,300 indirect jobs

• MP Materials’ Texas magnetics facility will source materials from Mountain Pass, California, and produce magnets powering approximately 500,000 EV motors per year, with potential to scale

• The facility is a substantial component of a $700 million investment MP Materials will make to fully restore the U.S. rare earth magnetics supply chain over the next two years

• Integrated recycling and leading environmental capabilities will deliver world class sustainability to support the energy transition

FORT WORTH, TEXAS., April 21, 2022 – MP Materials Corp. (NYSE: MP) today commemorates the start of construction at its first rare earth metal, alloy, and magnet manufacturing facility, located in Fort Worth, Texas. The first-of-its kind U.S. facility is a substantial component of a $700 million investment the company will make over the next two years to fully restore the U.S. rare earth magnetics supply chain. The project will create around 150 high-skill jobs and 1,300 indirect jobs and is located in Hillwood’s 27,000-acre, mixed-use development, AllianceTexas.

In parallel, MP Materials and General Motors (NYSE: GM) are co-announcing a definitive supply agreement to produce alloy and magnets for GM’s EV programs. The definitive supply agreement solidifies the terms of a binding agreement announced by MP Materials and GM in December. Under the long-term agreement, MP Materials will supply U.S.-sourced and manufactured rare earth materials, alloy, and finished magnets for the electric motors in more than a dozen models using GM’s Ultium Platform, with a gradual production ramp that is expected to begin in late 2023, starting with alloy.

MP Materials’ Fort Worth facility will have the capacity to produce approximately 1,000 tonnes of neodymium-iron-boron (NdFeB) magnets per year, supporting the production of approximately 500,000 EV traction motors, with room to scale. In addition to EVs, NdFeB magnets are critical inputs to robots, wind turbines, drones, defense systems, and many other high-growth technologies. Adamas Intelligence, an independent research firm, forecasts that global demand for NdFeB magnets will triple by 2035 on the back of rising demand for EV traction motors, wind power generators, energy efficient consumer appliances, and more.

In February, the Department of Defense awarded MP Materials $35 million to refine and separate heavy rare earth elements at the company’s Mountain Pass, California, rare earth materials production facility. MP’s Texas magnetics factory will source refined feedstock from Mountain Pass and transform it into finished products, delivering an end-to-end supply chain, including mining and refining, metal, alloy, and magnet manufacturing, and recycling.

Mountain Pass is a closed loop, zero-discharge facility with a dry tailings process that recycles more than 1.7 billion liters of water per year. To optimize for efficiency and sustainability, byproduct generated from alloy and magnet manufacturing will be recycled in a closed loop to every extent possible.

James Litinsky, Founder, Chairman, and Chief Executive Officer, MP Materials

“Bringing magnetics capabilities home is transformational for MP Materials and America’s supply chains. I am very proud that after a series of executive orders spanning multiple presidential administrations MP Materials is leading the restoration of the full supply chain and the revitalization of the American manufacturing spirit in our sector.”

Anirvan Coomer, Executive Director, Global Purchasing & Supply Chain, General Motors

“The new MP Materials magnetics facility in Fort Worth, Texas, will play a key role in GM’s journey to build a secure, scalable, and sustainable EV supply chain. As the foundational automotive customer of the Fort Worth facility, GM will use the products from this plant in the GMC HUMMER EV, Cadillac LYRIQ, Chevrolet Silverado EV, and more than a dozen models based on GM’s Ultium platform. We also look forward to collaborating with MP Materials from a public policy perspective to seek policies that are supportive of the establishment of an efficient U.S.-based rare earth and magnet supply chain.”

Ross Perot Jr., Chairman, Hillwood and The Perot Group

“Today is an exciting day for North Texas and our entire country. MP Materials is not only bringing their state-of-the art magnetics facility to AllianceTexas, but also reshoring important next-generation manufacturing jobs to America. Securing and developing rare earth materials is one of the most important national security issues of our day, and we’re proud that AllianceTexas can partner with MP Materials to play a key role in America’s ability to power its future.”

The Honorable Ted Cruz, U.S. Senator for Texas

“The United States needs to do everything we can to end our dangerous dependence on China for rare earth elements and critical minerals across the entire supply chain. It is both significant and important that MP Materials is going beyond mining and into alloying and manufacturing, and I’m deeply proud of the role Texas is playing in these projects.”

The Honorable Kay Granger, U.S. Representative for Texas

“MP’s investment will bring hundreds of new jobs and millions in economic growth to the TX-12 community. Rare earth materials are crucial for many defense systems, and by producing these much-needed magnets, this facility will reduce our dependence on countries like China. For the sake of our national security, we must continue to increase domestic rare earth production, and I’m proud that we will do that right here in Fort Worth.”

The Honorable Michael Burgess, U.S. Representative for Texas

“When it comes to solving the energy crisis facing our nation, we need innovative and visionary solutions at the forefront. It is exciting that Texas is able to welcome another energy provider today with the groundbreaking of MP Materials’ new rare earth alloying and magnet manufacturing facility. I hope you will join me in welcoming MP Materials to our community.”

The Honorable Beth Van Duyne, U.S. Representative for Texas

“Rare earth magnets are essential for U.S. economic and national security, and it is vital to our national interest that we manufacture these components at scale here at home. I applaud MP Materials for building this landmark facility in Fort Worth, and I’m pleased that Texas is at the forefront of restoring this important supply chain back to America.”

The Honorable Marc Veasey, U.S. Representative for Texas

“Rare earth magnets are critical to the energy transition and security of the United States. It is essential we manufacture these components in the United States from domestic materials sourced in an environmentally responsible manner. The people of TX-33 are prepared to support and lead this effort.”

The Honorable Greg Abbott, Governor of Texas

“Congratulations to MP Materials on the groundbreaking of their new magnet manufacturing facility and engineering headquarters in Fort Worth. This incredible investment will not only create more than 100 new jobs for hardworking Texans, but will also bolster the state’s supply chain in high-tech industries while solidifying Texas as a mecca for advanced manufacturing and innovation. It’s thanks to industry innovators like MP Materials that ‘Made in Texas’ continues to be the most powerful global brand.”

The Honorable Mattie Parker, Mayor of Fort Worth

“This new MP Materials facility is an excellent fit for the groundbreaking work being done at AllianceTexas, and it presents an incredible opportunity to bring more advanced manufacturing jobs home to the U.S. right here in Fort Worth. Our local, state, and national economic and mobility goals require secure development of rare earth magnets, and I am proud that Fort Worth will serve as a center for our nation’s focus on advancing this effort.”
