Is MP Stock a Buy, Hold or Sell After Its 98.9% Six-Month Rally?

MP Materials shares have surged 98.9% over the past six months after clinching strategic deals — including a long-term, roughly $500m agreement to supply Apple with recycled rare-earth magnets, a U.S. Department of War partnership to fast‑track a domestic magnet supply chain and a JV with Saudi Ma’aden to build a refinery — alongside a strong production ramp (NdPr production 721 MT in Q3, 1,881 MT YTD, +114% year‑over‑year). The company projects revenue growth (Zacks: +13.7% in 2025, +79% in 2026) with consensus EPS swinging from a -$0.21 loss in 2025 to $0.69 in 2026, but estimates have been revised down recently and MP trades at a steep forward PS of 25.4x versus the industry’s 1.4x. For institutional investors, MP’s unique U.S. feedstock and magnet capacity buildout position it to benefit from onshoring and defense demand, yet the premium valuation and recent downward earnings revisions argue for existing holders to remain engaged while new entrants await a better entry point.

Analysis

MP Materials has delivered a 98.9% share-price gain over the past six months, markedly outperforming the industry (+11.8%) and the S&P 500 (+15.9%), driven by a roughly $500 million long-term recycled magnet agreement with Apple, a U.S. Department of War (DoW) partnership to accelerate a domestic magnet supply chain and consecutive strong production quarters. The company also announced a strategic joint venture with Saudi Ma’aden to develop a rare-earth refinery and plans a second domestic magnet plant (the 10X Facility) to reach 10,000 metric tons of U.S. magnet capacity, which together deepen its strategic positioning in onshoring and defense-linked demand.

Operationally, NdPr production reached 721 metric tons in Q3 (+51% YoY) and 1,881 MT year-to-date (+114% YoY), surpassing full-year 2024 output, while REO production was 13,254 MT in Q3 (down 4% YoY but the second-highest quarter). Street expectations imply revenue growth of ~13.7% in 2025 and 79% in 2026 with EPS moving from a consensus -$0.21 in 2025 to $0.69 in 2026, yet estimates have trended lower over 90 days and the stock trades at a steep forward P/S of 25.41x versus the industry 1.44x (Value Score F).

The combination of unique U.S. feedstock, defense and Apple contracts and an accelerating production ramp creates a credible long-term growth runway, but premium valuation and recent downward estimate revisions amplify execution and macro risks; investors should prioritize operational cadence, margin progression and milestone delivery on the 10X Facility and JV before adding material new exposure.

Key Decisions for Investors

• Existing holders should maintain positions to participate in long-term upside from DoW funding, Apple demand and NdPr ramp, but consider trimming size if valuation-driven risk tolerance is low
• New investors should wait for a meaningful pullback or for sustained positive revisions to earnings estimates before initiating material exposure
• Monitor quarterly NdPr production, REO conversion rates, 10X Facility construction milestones and Ma’aden JV progress as near-term catalysts and risk indicators
• Manage position sizing or use hedges given the 25.4x forward P/S premium and recent downward estimate revisions; consider diversifying rare-earth exposure across peers such as Lynas or Energy Fuels
