Fair Pay & Worker Respect

20

As a mining and processing company, MP Materials operates in a high-risk sector for workplace safety and labor standards, but its core business model does not inherently advance or harm fair pay and worker respect practices, which are determined by company policy and operational management. MP Materials demonstrates strong performance in safety, retention, and employee ownership, though it lacks union representation. - **Living Wage Coverage**: While a specific 'living wage' percentage isn't cited, the company grants equity ownership to 100% of full-time employees.

1
2
This aligns with the tier for 100% living-wage earners with ownership stake options. - **Collective Bargaining Share**: The company explicitly reports 0% union coverage.
3
4
While it frames this as fostering 'direct relationships,' the rubric tiers 0-5% coverage with passive resistance or lack of agreements at -60.
5
6
- **Safety Incident Rate**: The company reported a Total Recordable Incident Rate (TRIR) of 1.47 in 2023 and 1.60 in 2024.

This is consistent with high-level comprehensive coverage (Tier 40).

Fair Trade & Ethical Sourcing

10

As a primary extractor and processor of rare earth minerals, the company is inherently tied to the risks of the mining sector, including supply chain transparency and human rights due diligence. While their domestic operations in the U.S. are subject to strict labor regulations, the inherent nature of the mining industry requires active management of sourcing ethics, making the value applicable but neutral until behavioral evidence of their specific supply chain practices is evaluated. MP Materials (MP.NYSE) demonstrates a strong commitment to ethical sourcing through its vertically integrated domestic operations and rigorous supplier requirements. For **forced_child_labour_incidents**, the company is scored at Tier 20. Multiple sustainability reports (2024 and 2025) confirm zero substantiated human rights violations or incidents of child/forced labor to date.

- **Whistleblower Policy:** The company maintains a 'Policy for Reporting Concerns' with a secure, anonymous 24/7 hotline managed by an independent third party (Red Flag Reporting).
9
10
The policy explicitly prohibits retaliation and includes procedures for reporting to the Audit Committee.
11
12
13
It is tiered at 10 as reports are investigated, though specific resolution timeframes are not quantified.
14
15
- **Anti-Corruption Policy:** MP Materials maintains a comprehensive Anti-Bribery and Corruption Policy within its Code of Business Conduct and Ethics.
16
17
It reported zero incidents of corruption in 2023 and 2024 and requires supplier compliance with the FCPA, supporting a tier of 10.
18
19
20
- **Third-Party Verification:** While the company has achieved an EcoVadis Bronze Medal (top 35%) and an independent examination of its Green Bond allocation, its primary sustainability reports explicitly state that the non-financial data has not been subject to a third-party audit.
21
22
23
It is currently 'seeking' third-party verification for its IRMA self-assessment.
24
25
26
This limited scope of verification (approx. 25% of broader ethical/ESG claims) results in a tier of -70.

No War, No Weapons

-30

While the company's materials are essential for green energy, they are also explicitly marketed for 'defense applications,' meaning the company's core business directly supplies the defense industrial base and military supply chains. MP Materials maintains a deep strategic partnership with the U.S. Department of Defense (DoD), which significantly impacts its alignment with the 'No War, No Weapons' value. According to the evidence, the DoD is the company's largest shareholder, holding a 15% equity stake through a $400 million investment in preferred stock.

1
2
The company has entered into a multibillion-dollar partnership with the DoD, which includes a $150 million loan and a 10-year offtake agreement where the DoD (and its designated customers) will purchase 100% of the magnets produced at the company's upcoming '10X' facility.
3
4
5
Furthermore, the DoD provides a price floor guarantee of $110/kg for NdPr products and shares in the company's EBITDA profits.
6
7
8
This level of financial and contractual integration with a national defense department places the company in a high-exposure tier for defense-related revenue and oversight. The company's primary products—neodymium-praseodymium (NdPr) and rare earth magnets—are explicitly classified as dual-use technology.
9
10
11
While they are essential for civilian applications like electric vehicles and wind turbines, they are also described as 'indispensable' for defense systems, including submarines, aircraft, and guided munitions.
12
13
14
On the positive side, MP Materials operates primarily in the United States (Mountain Pass, CA), and its sustainability reports confirm that it has no operations in active conflict zones.
15
16
The company maintains a zero-tolerance policy for forced labor and is working toward formalizing conflict mineral certifications through the Responsible Minerals Initiative (RMI), though it currently notes that standard conflict mineral disclosures are not applicable to its primary US-based extraction operations.
17
18
19
Additionally, its agreements with the DoD include strict compliance controls that prohibit sales to 'restricted buyers,' effectively preventing sales to embargoed regimes.
