MP Materials Corp. entered into a Credit Agreement dated August 25, 2025 under which MP Materials is the parent borrower and JPMorgan Chase Bank, N.A. serves as administrative agent and collateral agent, with lenders and letter-of-credit issuers as parties. The facility permits borrowing priced either at a one-month SOFR rate plus 1.00% or a Base Rate of 1.00%, plus an additional margin that varies by the company’s total leverage: 1.75%�2.50% per annum for SOFR-based loans and 0.75%�1.50% per annum for Base Rate loans. The filing includes an interactive data file formatted as inline XBRL and is signed by Elliot D. Hoops, General Counsel and Secretary.
MP Materials Corp. reported stronger top-line activity in the first half of 2025, with revenue rising to $118.2 million for the six months ended June 30, 2025 from $79.9 million a year earlier, driven by higher NdPr oxide/metal sales and the start of magnetic precursor product shipments from its Independence Facility. Magnetics revenue began in Q1 2025 and contributed $19.9 million in the quarter. The company held substantial liquidity with $261.5 million of cash and $492.1 million of short-term investments, totaling $753.7 million.
Despite revenue growth, MP reported operating losses: a net loss of $30.9 million for Q2 2025 and $53.5 million for the six months, reflecting higher operating costs and SG&A. Total debt principal was $930.5 million (carrying amount ~$910.8 million), and deferred revenue from GM prepayments totaled $124.9 million. The company announced strategic shifts in 2025: it ceased shipments of concentrate to China and, in July 2025, entered DoD agreements to expand domestic magnet and HREE capacity, including commitments that provide price floors and purchase assurances for future production.
