USA Rare Earth, Inc. has appointed Thras Moraitis as its new Chief Executive Officer, effective October 1, 2026, succeeding Barbara Humpton who will retire as CEO and Board Director. The leadership transition follows the anticipated completion of USA Rare Earth's combination with Serra Verde by the end of August. Michael Blitzer, current Chairman of the Board, has been elected Executive Chairman, effective immediately, to guide the company's strategic direction during this period of integration and execution.
Mr. Moraitis currently serves as Chief Executive Officer of Serra Verde, a position he has held since January 2023. Under his leadership, Serra Verde transformed into the only large-scale producer of the four critical magnetic rare earths outside of Asia. In April 2026, Serra Verde entered into a definitive agreement to combine with USA Rare Earth to create a platform for the first fully integrated, Western mine-to-magnet supply chain. During the interim period before assuming the CEO role, Mr. Moraitis will continue to oversee the combined company’s operations as President.
Prior to his tenure at Serra Verde, Mr. Moraitis served on the Executive Committee of Xstrata, led by CEO Sir Mick Davis. During that period, he and the team grew Xstrata into a US$65B company before its sale to Glencore in 2013. His career also includes roles as Chief Development Officer of EuroChem Group AG and co-founder of X2 Resources, a US$5.6B mining investment fund.
Michael Blitzer, the newly appointed Executive Chairman, is a Founder and Managing Partner of Inflection Point. Since USA Rare Earth's public listing in 2025, he has played a central role in setting the company's strategic direction, including efforts to secure U.S. government financing. He has agreed to restrictions on the transfer of his USA Rare Earth common stock until certain strategic funding release milestones under the government financing are satisfied.
Ms. Humpton has been instrumental in steering USA Rare Earth's mine-to-magnet strategy, overseeing the securing of landmark public-private partnerships and establishing a global footprint spanning critical processing, metals, and magnet capabilities. The Board of Directors expressed gratitude for her contributions, noting that the transition aligns with the company's shift toward operational execution following the Serra Verde merger.
