Barbara Humpton is Chief Executive Officer of USA Rare Earth, leading the company’s mission to build the first fully integrated rare earth value chain outside of China — from mining, through processing, metal and alloy production, to magnet manufacturing. Throughout her career, she has been motivated by being part of missions that matter, and there is nothing more critical to national and global security than securing a domestic integrated value chain for rare earth minerals and magnets.
From 2018 through 2025, Humpton served as President and CEO of Siemens USA, overseeing approximately 45,000 employees across 50 states and Puerto Rico and more than $21 billion in annual revenue. Prior to joining Siemens in 2011, she served as a Vice President at Booz Allen Hamilton and Lockheed Martin Corporation with responsibility for large-scale system integration of biometrics programs, border and transportation security, and critical infrastructure protection.
Humpton is a graduate of Wake Forest University with a bachelor’s degree in mathematics. She is Chairperson of the Center for Strategic and Budgetary Assessments (CSBA), Vice Chair of Chief Executives for Corporate Purpose (CECP), and serves on the board of the Federal Reserve Bank of Richmond and the Economic Club of Washington, D.C.
