MP Materials Shares Tumble Following Strategic Partnership Announcement

MP Materials shares experienced a sharp decline in Thursday’s trading session, falling approximately 10.8% to $56.68. This significant pullback comes after the stock’s spectacular rally earlier in the week, which was fueled by news of a landmark joint venture involving the U.S. Department of War and Saudi Arabian mining giant Maaden.

Profit-Taking Emerges After Rally

The primary driver behind today’s sell-off appears to be profit-taking following the recent surge. Investors are capitalizing on gains after the stock’s nearly 300% ascent since the beginning of the year. The dramatic upward move was triggered by MP Materials confirming a binding agreement to establish a rare earths refining facility in Saudi Arabia through a joint venture.

Market participants are demonstrating classic “sell the news” behavior despite the venture’s strategic importance. The partnership solidifies MP Materials’ position as a critical national security asset while expanding U.S. industrial capacity into allied territory.

Joint Venture Structure Reveals New Industry Alignment

The arrangement represents a significant shift in the sector’s financial landscape:

• Majority Stake: Maaden will control 51% of the joint venture
• U.S. Interest: MP Materials and the Department of War collectively hold the remaining 49%
• Funding Model: The U.S. Department of War is providing non-recourse financing for the American portion, while MP Materials contributes technical expertise

Despite these fundamentally positive long-term implications, the stock retreated from Wednesday and Thursday’s peaks above $63 as traders locked in profits.

Should investors sell immediately? Or is it worth buying MP Materials?

Prominent Investor Increases Stake

Amid the market volatility, another development captured investor attention: Australian mining magnate Gina Rinehart has become MP Materials’ largest shareholder. Through her investment vehicle Hancock Prospecting, she raised her stake to 8.4% during the third quarter of 2025, surpassing even CEO James Litinsky’s position.

However, this vote of confidence from one of the world’s most successful investors has thus far failed to stem the selling pressure. The market continues to navigate turbulent conditions as the company’s valuation—approximately $11 billion—reflects substantial growth expectations. MP Materials has effectively transformed from a pure-play mining operation into a significant geopolitical participant.

Valuation Concerns and Analyst Outlook

The company’s current valuation presents challenges. Despite reporting record production levels, MP Materials posted a net loss in its third-quarter results, indicating the stock trades at a premium to current financial performance. Today’s decline suggests investors remain cognizant of execution risks associated with constructing refining facilities overseas.

From a technical perspective, the stock is seeking support near the $55 level. A breach of this zone could signal further consolidation ahead.

Market experts maintain constructive views, however. Goldman Sachs initiated coverage this week with a “Buy” rating and a $77 price target. The firm’s analysts point to substantial value creation potential through vertical integration and government partnerships. Investors now await the next significant catalyst: the earnings report scheduled for February 19, 2026.
