MP Materials is an operating rare-earth producer worth about $10 billion; NioCorp is a pre-revenue, $601 million Nebraska developer betting on an $800 million federal loan.
At a glance
- MP Materials posted Q2 2026 revenue and price-protection income of $126.1 million, more than double the prior-year period, with neodymium-praseodymium (NdPr) sales volumes up 127% year over year.
- NioCorp remains pre-revenue; its August 11, 2026 updated feasibility study projects a 40-year Elk Creek mine life with a $4.1 billion pre-tax net present value.
- MP holds a Pentagon price-protection deal guaranteeing it a minimum $110 per kilogram for NdPr, which generated $17.6 million in income in a single 2026 quarter.
- NioCorp has applied to the US Export-Import Bank for up to $800 million in debt financing; the application has cleared the first review stage and is now in an independent technical review.
What happened
Investors comparing US critical-minerals stocks are increasingly weighing MP Materials against NioCorp Developments, two companies pursuing very different paths to the same goal: reducing American reliance on Chinese-processed rare earths and specialty metals. MP Materials (NYSE: MP) closed at $54.76 on August 31, 2026, down 2.44% on the day, giving it a market capitalization of roughly $10 billion. NioCorp (NASDAQ: NB) closed the same session at $4.20, up 1.69%, valuing the company at about $601 million. The gap in size reflects a gap in stage: MP already runs a producing mine and processing plant in California, while NioCorp is still assembling the financing to build its Elk Creek project in Nebraska.
The details
MP Materials and NioCorp both sit inside the same US policy push to build critical-minerals supply chains outside China, but they occupy opposite ends of the development timeline. MP Materials is the only fully integrated rare-earth producer in the United States, running the Mountain Pass mine, a separation and processing plant, and a magnet-manufacturing operation under one roof. That integration showed up directly in its second-quarter 2026 results: revenue and price-protection income reached $126.1 million, more than double the year-earlier figure, as NdPr sales volumes climbed 127% year over year. Adjusted EBITDA came in at $28.5 million, an improvement of $41 million from a year earlier, and the company is now commissioning a dysprosium-terbium separation circuit while guiding toward a third consecutive quarter of NdPr production above 1,000 metric tons.
A US Department of Defense price-protection agreement sits underneath that operating base. The deal guarantees MP a minimum of $110 per kilogram for its NdPr output, insulating the company from the risk that Chinese producers push prices below what Mountain Pass costs to run. That protection generated $17.6 million in income in a single 2026 quarter, real cash rather than a projection.
NioCorp is building toward the same kind of government backing but hasn't secured it yet in the same form. Its Elk Creek project in southeast Nebraska would mine niobium, scandium, titanium and several rare-earth elements from a single ore body, and an updated feasibility study released August 11, 2026 raised the stakes considerably: a 40-year mine life, a $4.1 billion pre-tax net present value at an 8% discount rate, a 24% pre-tax internal rate of return, and roughly $37.4 billion in projected life-of-mine revenue, all supported by 45.9 million tons of proven and probable reserves. The company has also lined up 75% of its planned ferroniobium output under definitive offtake agreements and locked in 12 tons a year of scandium sales against a targeted 100 tons of annual production.
What NioCorp doesn't yet have is MP's revenue or MP's finished financing. It has applied to the US Export-Import Bank for up to $800 million in project debt, an application that cleared the bank's first technical review committee back in 2023 and is now working through a second-level independent technical review handled by RPMGlobal USA. Until that loan, or an equivalent financing package, actually closes, Elk Creek stays a construction project on paper rather than a mine generating cash. NioCorp did pick up a $10 million Pentagon Title III award, a smaller and earlier-stage version of the kind of government support MP already converts into quarterly income.
The two stocks are, in effect, pricing two different kinds of risk. MP's roughly $10 billion valuation reflects a business already generating revenue, backed by a government price floor and long-term supply relationships. NioCorp's much smaller $601 million valuation reflects a project with a larger long-run resource base on paper but a financing package, a construction timeline and a first dollar of revenue that all still lie ahead of it.
Why it matters
The contrast between an operating, government-backed rare-earth producer and a pre-revenue developer chasing a federal loan illustrates how uneven the build-out of a US critical-minerals supply chain still is. Washington's interest in reducing dependence on Chinese processing is real and is showing up as actual cash for MP Materials, but that same policy push has not yet translated into closed financing for earlier-stage projects like Elk Creek, even ones with large resource estimates on paper.
Our read
Outlook: neutral. The two stocks reflect different stages of the same US critical-minerals build-out rather than a single directional catalyst: MP Materials' operating results support its existing valuation, while NioCorp's larger long-run project economics remain contingent on financing that has not yet closed, leaving no clear near-term price direction for either as a pair.
What to watch
- Progress of NioCorp's EXIM Bank loan application through its independent technical review stage
- MP Materials' Dy-Tb circuit commissioning and first shipments from Mountain Pass to its Independence facility
- Any additional offtake agreements NioCorp signs for its remaining uncontracted niobium and scandium output
- MP Materials' third-quarter 2026 NdPr production figures against its guidance of more than 1,000 metric tons

Detailed analysis
Timeline
- 2023-10-01: NioCorp's EXIM Bank loan application clears the bank's first technical review committee (TRC-1), roughly.
- 2026-08-06: MP Materials reports second-quarter 2026 results: $126.1 million in revenue and price-protection income, with NdPr sales volumes up 127% year over year.
- 2026-08-11: NioCorp releases an updated Elk Creek feasibility study projecting a 40-year mine life and a $4.1 billion pre-tax net present value across eight products.
- 2026-08-31: MP Materials closes at $54.76 (about a $10 billion market cap) and NioCorp closes at $4.20 (about a $601 million market cap).
Demand Drivers
MP Materials' NdPr sales volumes rose 127% year over year in the second quarter of 2026, and the company has long-term magnet supply agreements with General Motors and Apple that provide committed demand beyond its government price floor.
Supply Drivers
MP Materials' Mountain Pass facility is the only fully integrated rare-earth mining, processing and magnet-manufacturing operation in the United States. NioCorp's Elk Creek project would add a second major domestic source of niobium, scandium, titanium and rare earths, but only once construction and financing are complete.
Government Policies
A US Department of Defense price-protection agreement guarantees MP Materials a minimum of $110 per kilogram for its NdPr output, generating $17.6 million in income in a single 2026 quarter. NioCorp has received a $10 million Pentagon Title III award and has an $800 million loan application working through US Export-Import Bank due diligence.
Geopolitical Risks
Both companies' investment cases are tied to US efforts to reduce dependence on Chinese-controlled rare-earth and specialty-metals processing, a policy priority reflected in MP's DoD deal and NioCorp's EXIM Bank application and Pentagon award.
Mining Production
MP Materials is an operating producer guiding toward a third consecutive quarter of NdPr production above 1,000 metric tons at Mountain Pass. NioCorp remains pre-production; its August 2026 feasibility study outlines a 40-year mine life at Elk Creek backed by 45.9 million tons of proven and probable reserves, but construction financing is not yet closed.
What could lift prices
- MP Materials is already generating revenue and adjusted EBITDA, backed by a government-guaranteed price floor that removes a major source of earnings volatility.
- NioCorp's updated feasibility study raised Elk Creek's projected pre-tax net present value to $4.1 billion across eight planned products, up from a narrower three-product plan in 2022.
- NioCorp has locked in 75% of its planned ferroniobium output under definitive offtake agreements ahead of any construction financing close.
What could weigh on prices
- NioCorp's entire investment case still depends on closing an EXIM Bank loan of up to $800 million or an equivalent financing package that has not yet been finalized.
- MP Materials trades at a market capitalization roughly 16 times its quarterly revenue run rate, leaving less room for error if government support or magnet demand growth slows.
- NioCorp generates no current revenue, meaning its share price rests entirely on project economics that assume construction proceeds on schedule.
Country impact
| Country | Impact | Reason |
|---|---|---|
| United States | High | Both companies are central to US efforts to build a domestic rare-earth and critical-minerals supply chain independent of China, with MP already receiving Pentagon price-protection payments and NioCorp pursuing an Export-Import Bank loan for its Nebraska project. |
Industry impact
| Industry | Effect | Reason |
|---|---|---|
| Automotive | Positive | MP Materials' rising NdPr output and long-term magnet supply agreements with automakers support more predictable supply of rare-earth magnets used in EV traction motors. |
| Defense | Positive | Both companies' government backing reflects the defense sector's strategic interest in securing domestic sources of rare earths, niobium, scandium and titanium used in alloys and magnets. |
| Aerospace | Positive | NioCorp's Elk Creek project targets niobium, scandium and titanium products used in high-strength, lightweight aerospace alloys. |
Who gains, who loses
- MP Materials: A government-guaranteed price floor, rising NdPr sales volumes and long-term customer agreements give it a revenue base its development-stage peers don't yet have.
- NioCorp: An expanded eight-product feasibility study and existing offtake commitments strengthen its case for the EXIM Bank financing it needs to build Elk Creek.
- NioCorp: Its investment case remains hostage to an EXIM Bank due-diligence process it does not control, delaying any path to construction and revenue.
Other ways this could play out
- If the EXIM Bank finalizes NioCorp's loan and Elk Creek construction proceeds on schedule, the stock's valuation gap with operating peers like MP Materials could narrow as the project nears its first production.
- If MP Materials' Dy-Tb circuit ramp and Independence facility shipments underperform guidance, its premium valuation relative to current revenue could compress.
Price risks
- A delay or rejection of NioCorp's EXIM Bank loan application could push back Elk Creek's construction timeline and pressure the stock.
- Any change to the terms of MP Materials' DoD price-protection agreement would directly affect its guaranteed NdPr price floor.
- A slowdown in EV or magnet demand growth could weigh on both companies' longer-term rare-earth volume assumptions.
