MP Materials Corp. (MP) Down 4.7% — Time to Execute the Exit Plan?
MP Materials Corp. (MP) spent the latest session under clear selling pressure, retreating 4.65% to close at $66.08 on the NYSE. The stock lost $3.22 from the prior close of $69.30, extending a pattern of sliding price action and signaling that shares are losing ground in the near term. Trading was active, with 4,070,586 shares changing hands, highlighting heightened interest as the stock moved lower.
The pullback stands out in the broader materials space, where several peers such as Air Products and Chemicals (APD), Albemarle (ALB), and Dow (DOW) have also faced intermittent headwinds, but MP’s latest move marks a notably steeper single-day retreat. The stock’s slide suggests that sellers are firmly in control for now, with recent sessions skewed toward downside pressure rather than recovery attempts. Until the price can stabilize and establish firmer support, the prevailing trend points to a market that is still reassessing the shares and is currently more inclined to sell into strength than to bid aggressively at current levels.
Why MP Materials Corp. Price is Moving Lower
The recent surge in MP Materials Corp.’s share price is running into clear fundamental headwinds that can justify renewed downside pressure. Despite the January spike on upbeat sentiment around critical minerals and strategic agreements, the company remains meaningfully unprofitable, with an EPS of -$0.71 and a steep profit margin of -50.54%. Revenue trends are moving the wrong way: the latest quarter’s $53.55 million in sales fell 6.7% from the prior quarter and nearly 15% year over year. That combination of contracting revenue and deep losses raises concerns that the rally is running ahead of the company’s ability to translate operational milestones into sustainable earnings.
Investors are also contending with elevated volatility and mixed signals from Wall Street. Although analysts have shifted toward a “Moderate Buy” consensus with rising price targets, at least one major bank recently cut its target even as it maintained a positive rating — a sign that expectations are being tempered. The stock’s sharp swings in early January, moving from the low $50s to the upper $60s in a short span, suggest that short-term traders rather than long-term fundamentals may be driving price action. Against a backdrop of weak margins and declining revenue, insider selling and the inherently cyclical nature of the materials space add further reasons for caution. Even with a strong cash position and record NdPr production, the market is increasingly questioning how long it will take for these positives to overcome current financial weakness, putting downward pressure on the share price as optimism is repriced.
What is the MP Materials Corp. Rating - Should I Sell?
Weiss Ratings assigns MP Materials Corp. (MP) a D rating. Current recommendation is Sell. The stock was downgraded on 8/11/2025, signaling a worsening risk/reward profile even within a generally challenged Materials sector. While a D rating does not imply imminent failure, it does indicate that, on a risk-adjusted basis, investors have historically been poorly compensated for the risks taken in this name.
The core issue is weak business performance. MP carries a Very Weak Growth Index, aligning with its double‑digit revenue decline of -14.90%. At the same time, the Very Weak Efficiency Index and a steep -50.54% profit margin show that management is struggling to convert operations into sustainable profits. These fundamental pressures help explain why shareholders have not been protected, even in periods where the stock may have shown intermittent strength.
On the risk side, the Excellent Solvency Index indicates a solid balance sheet and an ability to meet financial obligations, which is a clear positive. However, this strength is overwhelmed by a Weak Volatility Index and only Fair Total Return Index. In practice, that means investors have been exposed to meaningful price swings without receiving commensurate, consistent returns. Strong solvency alone has not translated into favorable shareholder outcomes.
Compared with sector peers such as Air Products and Chemicals, Inc. (APD, D+), Albemarle Corporation (ALB, D+), and Dow Inc. (DOW, D+), MP Materials stands on the weaker end of an already underperforming group. Those peers share Sell-level ratings but at slightly higher grades, reinforcing that MP is one of the less attractive choices in a difficult sector from a risk-adjusted perspective.
About MP Materials Corp.
MP Materials Corp. is a materials company focused on rare earth production, with operations that are heavily concentrated in a single asset: the Mountain Pass Rare Earth Mine and Processing facility in San Bernardino County, California. Through its Materials segment, the company extracts and processes rare earth ores into refined materials used primarily in high-performance magnets. This concentration in one mine and one primary processing complex exposes MP Materials to operational, regulatory, and environmental risks tied to that specific location and asset base.
The company’s Magnetics segment is designed to move further downstream in the rare earths value chain by producing magnetic precursor products. This involves converting rare earth materials into inputs for permanent magnets used in electric vehicles, wind turbines, and other advanced industrial applications. MP Materials positions itself as a rare earth producer in the Western Hemisphere, but it operates in a highly specialized, capital-intensive corner of the materials sector where technological, execution, and supply chain challenges are significant. Founded in 2017 and headquartered in Las Vegas, Nevada, the company remains relatively young compared to more established global competitors, with a business model that depends on successfully integrating mining, processing, and magnetics production in a market characterized by cyclical demand and strong overseas competition.
Investor Outlook
With MP Materials Corp. (MP) carrying a D (Sell) Weiss Rating, investors may want to exercise caution and closely monitor whether recent trading stabilizes or breaks to new lows. Watch sector-wide materials trends, any signs of improving profitability or cash generation, and whether the company can deliver more consistent total returns that might eventually support a rating upgrade.
