Overview

MP Materials Corp. is the largest producer of rare earth materials in the
Western Hemisphere. The Company owns and operates the Mountain Pass Rare Earth
Mine and Processing Facility ("Mountain Pass"), the only rare earth mining and
processing site of scale in North America. We estimate the rare earth
concentrate we produced and sold in 2021 represented approximately 15% of the
rare earth content consumed in the global market.

Rare earth elements ("REE") are fundamental building blocks of the modern
economy, impacting trillions of dollars in global economic activity through the
enablement of end products across industries including transportation, clean
energy, robotics, national defense and consumer electronics, among others.
Neodymium ("Nd") and praseodymium ("Pr") are rare earth elements which in
combination form neodymium-praseodymium ("NdPr"), which represents a majority of
the value contained in our rare earth concentrate. NdPr is most often utilized
in NdPr magnets, which are also commonly referred to as "neo," "NdFeB," "NIB,"
or permanent magnets and are made predominantly from an alloy of NdPr, iron and
boron. NdPr magnets are the most widely used type of rare earth magnets and are
critical for many advanced technologies that are experiencing strong secular
growth, including electric vehicles ("EV"), drones, defense systems, wind
turbines, robotics and many others. The rapid growth of these and other advanced
motion technologies is expected to drive substantial demand growth for NdPr.

We produce our materials at Mountain Pass, one of the world's richest rare earth
deposits, co-located with integrated state-of-the-art processing and separation
facilities. We acquired the Mountain Pass assets in 2017, restarted operations
from cold-idle status and embarked on a deliberate, two-stage plan to optimize
the facility and position the Company for growth and profitability. We commenced
mining, comminution, beneficiation, and tailings management operations, which we
designated Stage I of our multi-stage optimization plan, between December 2017
and February 2018.

We currently produce a rare earth concentrate that we sell to Shenghe Resources
(Singapore) International Trading Pte. Ltd. ("Shenghe"), an affiliate of Shenghe
Resources Holding Co., Ltd., which, in turn, typically sells that product to
refiners in China. These refiners separate the constituent REE contained in our
concentrate and sell the separated products to their customers. Upon completion
of our Stage II optimization project ("Stage II"), we anticipate producing
separated rare earth oxides ("REO"), including NdPr oxide, and selling these
products directly to end users, at which time we may no longer sell our
concentrate.

In February 2022, we commenced construction of our initial rare earth metal,
alloy and magnet manufacturing facility in Fort Worth, Texas (the "Fort Worth
Facility"). Furthermore, in April 2022, we entered into a definitive long-term
supply agreement with General Motors Company (NYSE: GM) ("GM") to supply
U.S.-sourced and manufactured rare earth materials, alloy and finished magnets
for the electric motors in more than a dozen models using GM's Ultium Platform,
with a gradual production ramp that is expected to begin in late 2023, starting
with alloy. The definitive long-term supply agreement solidifies the terms of a
binding agreement announced by the Company in December 2021. These developments
are a part of our Stage III downstream expansion strategy ("Stage III").

Key Performance Indicators

We use the following key performance indicators to evaluate the performance of
our business. Our calculations of these performance indicators may differ from
similar measures published by other companies in our industry or in other
industries. The following table presents our key performance indicators:

REO Production Volume

We measure our REO-equivalent production volume for a given period in metric
tons ("MTs"), our principal unit of sale. This measure refers to the REO content
contained in the rare earth concentrate we produce. Our REO production volume is
a key indicator of our mining and processing capacity and efficiency.

The rare earth concentrate we currently produce is a processed, concentrated
form of our mined rare earth-bearing ores. While our unit of production and sale
is a MT of embedded REO, the actual weight of our rare earth concentrate is
significantly greater, as the concentrate also contains non-REO minerals and
residual moisture from the production process. We target REO content of greater
than 60% per dry MT of concentrate (referred to as "REO grade"). The elemental
distribution of REO in our concentrate is relatively consistent over time and
production lot. We consider this the natural distribution, as it reflects the
distribution of elements contained, on average, in our ore. As noted above, upon
completion of Stage II, we expect to refine our rare earth concentrate to
produce separated rare earths, including NdPr oxide.

REO Sales Volume



Our REO sales volume for a given period is calculated in MTs. A unit, or MT, is
considered sold for purposes of this performance indicator once we recognize
revenue on its sale. Our REO sales volume is a key measure of our ability to
convert our production into revenue.

Realized Price per REO MT



We calculate the realized price per REO MT for a given period as the quotient
of: (i) our Total Value Realized (see below) for a given period and (ii) our REO
sales volume for the same period. We define Total Value Realized, which is a
non-GAAP financial measure, as our product sales adjusted for the revenue impact
of tariff rebates related to prior period sales.

Realized price per REO MT is an important measure of the market price of our
product. Accordingly, we calculate realized price per REO MT to reflect a
consistent basis between periods by eliminating the revenue impact of
tariff-related rebates. See the   "Non-GAAP Financial Measures"   section below
for a reconciliation of our Total Value Realized, which is a non-GAAP financial
measure, to our product sales, which is determined in accordance with generally
accepted accounting principles in the United States ("GAAP"), as well as the
calculation of realized price per REO MT.

Production Cost per REO MT



We calculate the production cost per REO MT for a given period as the quotient
of: (i) our Production Costs (see below) for a given period and (ii) our REO
sales volume for the same period. We define Production Costs, which is a
non-GAAP financial measure, as our cost of sales (excluding depletion,
depreciation and amortization) less stock-based compensation expense included in
cost of sales, shipping and freight costs, and costs attributable to certain
other sales, for a given period.

Production cost per REO MT is a key indicator of our production efficiency. As a
significant portion of our cash costs of Stage I production are fixed, our
production cost per REO MT is influenced by mineral recovery, REO grade, plant
feed rate and production uptime. See the   "Non-GAAP Financial Measures"
section below for a reconciliation of our Production Costs, which is a non-GAAP
financial measure, to our cost of sales (excluding depletion, depreciation and
amortization), which is determined in accordance with GAAP, as well as the
calculation of production cost per REO MT.

Key Factors Affecting Our Performance

We believe we are uniquely positioned to capitalize on the key trends of
electrification and supply chain security, particularly as domestic EV
production grows. Our success depends to a significant extent on our ability to
take advantage of the following opportunities and meet the challenges associated
with them.

Demand for REE

The key demand driver for REE is their use in a diverse array of growing end
markets, including: clean-energy and transportation technologies (e.g., traction
motors in EVs and generators in wind power turbines); high-technology
applications (e.g., miniaturization of smart phones and other mobile devices,
fiber optics, lasers, robotics, medical devices, etc.); critical defense
applications (e.g., guidance and control systems, global positioning systems,
radar and sonar, drones, etc.); and essential industrial infrastructure (e.g.,
advanced catalyst applications in oil refining and pollution-control systems in
traditional internal-combustion automobiles, etc.). We believe these drivers
will fuel the continued growth of the rare earth market, particularly the market
for NdPr and permanent magnets.

We believe we benefit from several demand tailwinds for REE, and particularly
for NdPr. These include the trend toward geographic supply chain
diversification, particularly in relation to China, the U.S. government strategy
to restore domestic supply of key minerals, and the increasing acceptance of
environmental, social and governance mandates. However, changes in technology
may also drive down the use of REE, including NdPr, in the components in which
they are now used, or lead to a decline in reliance on such components
altogether. We also operate in a competitive industry, and many of our key
competitors are based in China, where competitors may not be subject to the same
rigorous environmental standards and production costs are typically lower than
in the United States.

Maximizing Production Efficiency



In 2021, REO production was approximately 3.5x greater than the highest ever
production in a twelve-month period by the prior operator of Mountain Pass using
principally the same capital equipment. We achieved these results through an
optimized reagent scheme, lower process temperatures, better management of the
tailings facility, and a commitment to operational excellence, driving
approximately 95% uptime. We also believe that our Stage I optimization
initiatives enabled us to achieve world-class production cost levels for rare
earth concentrate.

The success of our business reflects our ability to manage our costs. Our
production achievements in Stage I have provided economies of scale to lower
production costs per unit of REO produced in concentrate. Stage II is designed
to enable us to continue to manage our cost structure for separating REE through
an optimized facility process flow. The reintroduction of the oxidizing roasting
step will allow us to capitalize on the inherent advantages of the bastnaesite
ore at Mountain Pass, which is uniquely suitable to low-cost refining by
selectively eliminating the need to carry lower-value cerium through the
separations process. The recommissioning of our natural gas-powered combined
heat and power ("CHP") plant, which was completed in December 2021, removed our
reliance on the regional electric power grid. Further, our location offers
significant transportation advantages that create meaningful cost efficiencies
in securing incoming supplies and shipping of our final products.

We currently operate a single site in a single location, and any stoppage in
activity, including for reasons outside of our control, could adversely impact
our production, results of operations and cash flows. In addition, several of
our current and potential competitors are government supported and may have
access to substantially greater capital, which may allow them to make similar or
greater efficiency improvements or undercut market prices for our product.

Development of Our REE Refining Capabilities and Other Opportunities



Stage II is focused on advancing our operations from the production of rare
earth concentrate to the separation of individual REE. Engineering, procurement,
construction, and other recommissioning activities are underway and involve
upgrades and enhancements to the existing facility process flow to reliably
produce separated REE at a lower cost and with an expected smaller environmental
footprint per unit of REO produced. As part of Stage II, we are in the process
of reintroducing an oxidizing roasting circuit, reorienting the plant process
flow, increasing product finishing capacity, improving wastewater management,
and making other improvements to materials handling and storage. Upon completion
of Stage II, we expect to be a global low-cost, high-volume producer of NdPr
oxide, which represents a majority of the value contained in our concentrate.

Further, we are pursuing opportunities to integrate further downstream into the
business of upgrading NdPr into metal alloys and magnets, including magnet
recycling, ultimately expanding our presence as a global source for rare earth
magnetics, as evidenced by our recent announcement to build the Fort Worth
Facility. We believe integration into magnet production will provide some
protection from commodity pricing volatility, while also enhancing our business
profile as the producer of a

                                       18
--------------------------------------------------------------------------------

critical industrial output in addition to a producer of resources. We expect our
Stage III efforts to continue to benefit from geopolitical developments,
including initiatives to repatriate critical materials supply chains.

In February 2022, we were awarded a $35.0 million contract by the Department of
Defense's Office of Industrial Base Analysis and Sustainment Program to design
and build a facility to process heavy rare earth elements ("HREE"). Successful
completion of this project will establish the first processing and separation
facility of its kind for HREEs in support of commercial and defense applications
in the United States. The HREE processing and separations facility will be built
at Mountain Pass and tie into our other Stage II facilities.

Our Mineral Reserves



Our ore body has proven over more than 60 years of operations to be one of the
world's largest and highest-grade rare earth resources. As of September 30,
2021, SRK Consulting (U.S.), Inc., an independent consulting firm that we
retained to assess our reserves, estimates total proven and probable reserves of
2.1 million short tons of REO contained in 30.4 million short tons of ore at
Mountain Pass, with an average ore grade of 6.36%. These estimates use an
estimated economical cut-off of 2.49% total rare earth oxide. Based on these
estimated reserves and our expected annual production rate of REO upon
completion of Stage II, as of September 30, 2021, our expected mine life was
approximately 35 years. We expect to be able to continue to grow our expected
mine life through exploratory drilling programs over time.

Mining activities in the United States are heavily regulated, particularly in
California. Regulatory changes may make it more challenging for us to access our
reserves. In addition, new mineral deposits may be discovered elsewhere, which
could make our operations less competitive.

Recent Developments and Comparability of Results

Offtake Agreement with Shenghe



In March 2022, the Company entered into an offtake agreement with Shenghe (the
"Offtake Agreement"), which became effective upon the termination of the A&R
Offtake Agreement (as discussed and defined in   Note 3, "Relationship and
Agreements with Shenghe,"   in the notes to the unaudited Condensed Consolidated
Financial Statements). The initial term of the Offtake Agreement is two years,
with the option to extend the term at the Company's discretion for an additional
one-year period. See the   "    Liquidity and Capital Resources    "   section
below for additional information on the termination of the A&R Offtake
Agreement.

Pursuant to the Offtake Agreement, and subject to certain exclusions, Shenghe
shall purchase on a "take or pay" basis the rare earth concentrate produced by
the Company as the exclusive distributor in China, with certain exceptions for
the Company's direct sales globally. In addition, at the discretion of the
Company, Shenghe may be required to purchase on a "take or pay" basis certain
non-concentrate rare earth products, although the Company may sell all
non-concentrate rare earth products in its sole discretion to customers or end
users in any jurisdiction. Under the Offtake Agreement, Shenghe will be paid a
variable commission on net proceeds to the Company.

The sales price of rare earth concentrate sold to Shenghe is based on an
agreed-upon price per MT, subject to certain quality adjustments depending on
the measured characteristics of the product, with an adjustment for the ultimate
market price of the product realized by Shenghe upon sales to their customers.
The sales price and other terms applicable to a quantity of offtake products are
set forth in monthly purchase agreements between the Company and Shenghe.

Tariff-Related Rebates



Starting in May 2020, the government of the People's Republic of China granted
retroactive tariff relief to certain importers of rare earth minerals including
Shenghe and its affiliates and other consignees of our products, relating to
periods prior to the formal lifting of the tariffs. As a result, Shenghe's
actual realized prices for the REO sold prior to May 2020 were higher than
originally reported to us and resulted in tariff rebates to end customers, which
contractually were due to Shenghe. On account of these rebates in the first
quarter of 2021, we received from Shenghe a credit against our contractual
commitments to them.

Impact of the COVID-19 Pandemic



In December 2019, a novel strain of coronavirus (known as "COVID-19") began to
impact the population of China. In March 2020, the outbreak of COVID-19 was
declared a global pandemic after growing both in the United States and globally.
The responses by governments, societies, and private sector entities to the
COVID-19 pandemic, which include temporary

                                       19
--------------------------------------------------------------------------------
  T    able of Contents
closures of businesses, social distancing, travel restrictions, "shelter in
place," and other governmental regulations and various economic stimulus
programs, have significantly impacted market volatility and general global
economic conditions, including significant business and supply chain disruption
as well as broad-based changes in supply and demand.

Since the onset of the COVID-19 pandemic in the first quarter of 2020, we have
experienced, at times, significant shipping delays due to congestion and
slowdowns at U.S. and international ports caused by shortages in vessels,
containers, and truckers, also disrupting the global supply chain. Congestion
and slowdowns have affected and may continue to affect the capacity at ports to
receive deliveries of products or the loading of shipments onto vessels. Despite
these factors, we have not experienced a reduction in production or sales due to
the COVID-19 pandemic; however, the COVID-19 pandemic has contributed to certain
cost and schedule pressures on the Stage II optimization project. The Company
has worked proactively and diligently to adjust working schedules and hours to
optimize logistics and shipping, which has thus far prevented a significant
negative impact on our product sales and has mitigated certain impacts on Stage
II construction and recommissioning progress. However, there can be no assurance
that the ongoing COVID-19 pandemic will not have a negative impact on our
production, sales, or growth projects in the future.

Furthermore, as the situation continues to evolve, including as a result of new
and potential future variants of COVID-19, the possibility of federal or state
mandates on vaccinations, or other factors that may affect international
shipping and logistics or involve responses to government actions such as
strikes or other disruptions, it is impossible to predict the effect and
ultimate impact of the COVID-19 pandemic on the Company's business and results
of operations. The extent and duration of any business disruptions, and related
financial impact, cannot be estimated at this time.

Revenue consists primarily of product sales, which pertain to our sales of rare
earth concentrate principally to Shenghe under the A&R Offtake Agreement for
sales between January 2021 and February 2022, or the Offtake Agreement for sales
beginning in March 2022. The sales price of rare earth concentrate sold to

The increase in product sales for the three months ended March 31, 2022, as
compared to the prior year period, was driven by higher REO sales volume, which
increased by 1,913 MTs, or 20%, to 11,706 MTs for the three months ended
March 31, 2022, and a higher realized price per REO MT, which increased by 135%,
reflecting higher demand for rare earth products. REO production volume
increased by 979 MTs, or 10%, to 10,828 MTs for the three months ended March 31,
2022, as compared to the prior year period, primarily reflecting higher ore feed
rates and mineral recoveries. The improvements were driven by continued
optimization of the flotation circuit, including operational consistency, and
adjustments to the reagent scheme developed through previous pilots that
resulted in higher production and improved product quality.

REO sales volume varies period-to-period based on the timing of shipments, but
sales volumes generally track our production volumes over time given our
take-or-pay arrangement with Shenghe. See the   "Quarterly Performance Trend"
section below for further discussion on realized price per REO MT.

Cost of sales (excluding depreciation, depletion and amortization) consists of
production- and processing-related labor costs (including wages and salaries,
benefits, and bonuses), mining and processing supplies (such as reagents), parts
and labor for the maintenance of our mining fleet and processing facilities,
other facilities-related costs (such as property taxes and utilities), packaging
materials, and shipping and freight costs.

Cost of sales for the three months ended March 31, 2022, increased year over
year primarily due to higher REO sales volume. The increase in production cost
per REO MT from $1,475 for the three months ended March 31, 2021, to $1,594 for
the three months ended March 31, 2022, is primarily due to higher payroll costs
and employee headcount, including an increase in hiring ahead of the completion
of our Stage II optimization project, as well as slightly higher energy costs
incurred following the restart of our CHP plant in January 2022. Cost discipline
and production efficiencies achieved during the three months ended March 31,
2022, more than offset higher material and supplies costs.

Notwithstanding an increase in employee headcount as we progress toward
completion of our Stage II optimization project, we believe our production cost
per REO MT has stabilized in the short-term, with operating efficiencies largely
offsetting raw material and logistics pressures. We anticipate additional
efficiency opportunities as we increase REO production volumes in our milling
and flotation circuit over time. In addition, production cost per REO MT may
vary period to period based on the timing of scheduled outages of our production
facilities for maintenance as well as anticipated tie-ins of certain Stage
II-related facilities in the next twelve months. See the   "Quarterly
Performance Trend"   section below for further discussion on production cost per
REO MT.

Selling, general and administrative expenses consist primarily of accounting,
finance and administrative personnel costs, including stock-based compensation
expense related to these personnel; professional services (including legal,
regulatory, audit and others); certain engineering expenses; insurance, license
and permit costs; facilities rent and other costs; office supplies; general
facilities expenses; certain environmental, health, and safety expenses; and
gain or loss on sale or disposal of long-lived assets.

Selling, general and administrative expenses for the three months ended
March 31, 2022, reflect an increase in stock-based compensation expense of $4.6
million, primarily from a grant of restricted stock units made to our chief
executive officer during the fourth quarter of 2021. Excluding stock-based
compensation expense, selling, general and administrative expense increased by
$2.5 million, or 28%, primarily due to increases in personnel costs and other
general and administrative costs.

Advanced projects, development and other consists principally of costs incurred
in connection with research and development of new processes or to significantly
enhance our existing processes, certain government contracts, and start-up
costs, as well as costs incurred to support growth and development initiatives
or other opportunities. Advanced projects, development and other for the three
months ended March 31, 2022, increased year over year primarily due to one-time
start-up costs associated with restart of our CHP plant as well as certain costs
associated with our Stage III initiatives that do not qualify for
capitalization.

Depreciation, depletion and amortization primarily consists of depreciation of
property, plant and equipment and depletion of mineral rights. The
year-over-year decrease in depreciation, depletion and amortization for the
three months ended March 31, 2022, primarily reflects a decrease in depletion
resulting from a revision to extend our estimate of the remaining useful life of
the mineral rights at the beginning of the fourth quarter of 2021.

Interest expense, net consists of the amortization of the debt issuance costs on
our Convertible Notes (as defined in the   "Liquidity and Capital Resources"
section below); the amortization of the discount on our debt obligation to
Shenghe; and the expense associated with the 0.25% per annum interest rate on
our Convertible Notes, offset by interest capitalized. Interest expense, net for
the three months ended March 31, 2022, increased year over year due to the
timing of the issuance of the Convertible Notes in March 2021.

Income tax expense consists of an estimate of U.S. federal and state income
taxes in the jurisdictions in which we conduct business, adjusted for federal,
state and local allowable income tax benefits, the effect of permanent
differences and any valuation allowance against deferred tax assets. The
effective tax rate (income taxes as a percentage of income or loss before income
taxes) was 24.5% and 21.8% for the three months ended March 31, 2022 and 2021,
respectively. The effective tax rates differed from the statutory tax rate of
21% primarily due to state income tax expense and a deduction limitation on
officer's compensation, partially offset by the California competes tax credit
awarded to us in the fourth quarter of 2021.

Quarterly Performance Trend



While our business is not highly seasonal in nature, we sometimes experience a
timing lag between production and sales, which may result in volatility in our
results of operations between periods. In addition, quarterly production is
impacted by the timing of scheduled outages of our production facilities for
maintenance. Our realized price per REO MT for the quarterly periods prior to
the second quarter of 2020 were adversely impacted by the imposition of Chinese
import duties in 2018 (and subsequent increase in May 2019). The import duties
were lifted in May 2020.

The following table presents our key performance indicators for the quarterly
periods indicated:

Liquidity and Capital Resources



Liquidity refers to our ability to generate sufficient cash flows to meet the
cash requirements of our business operations, including working capital and
capital expenditure needs, contractual obligations, debt service and other
commitments. In recent years, our principal sources of liquidity have been
financing through the consummation of the business combination with Fortress
Value Acquisition Corp. in November 2020, the issuance of the Convertible Notes
in March 2021, and net cash from operating activities. As of March 31, 2022, we
had $1,233.3 million of cash and cash equivalents and $690.0 million principal
amount of long-term debt.

Our results of operations and cash flows depend in large part upon the market
prices of REO and particularly the price of rare earth concentrate. Rare earth
concentrate is not quoted on any major commodities market or exchange and demand
is currently constrained to a relatively limited number of refiners, a
significant majority of which are based in China. Although we believe that our
cash flows from operations and cash on hand are adequate to meet our liquidity
requirements for the foreseeable future, uncertainty exists as to the market
price of REO, especially in light of the ongoing COVID-19 pandemic, including
the emergence of new and potential future variants.

Our current working capital needs relate mainly to our mining and beneficiation
operations. Our principal capital expenditure requirements relate mainly to the
periodic replacement of mining or processing equipment, as well as our Stage II
optimization project and related HREE project and the development of the Fort
Worth Facility. Our future capital requirements will depend on several factors,
including future acquisitions and potential additional investments in further
downstream production.

The completion of our mission to become a fully integrated domestic magnetics
producer is expected to be capital intensive. In accelerating the strategic
opportunity for the separation of HREE, enhancements were made to the design and
scope of the initial Stage II project. Including these enhancements and other
factors impacting the remaining cost of completion, and including the initial
costs of a HREE separation facility and the development and construction costs
of the Fort Worth Facility as well as other growth and infrastructure
investments at Mountain Pass, we expect to incur approximately $500 million of
capital costs in 2022. We expect to incur further costs to complete the HREE
separation facility and the Fort Worth Facility in 2023 and 2024.

Our estimated costs or estimated time to complete these projects may increase,
potentially significantly, due to factors outside of our control. While we
believe that we have sufficient cash resources to fund these initiatives and
operating working capital in the near term, we cannot assure this. If our
available resources prove inadequate to fund our plans or commitments, we may be
forced to revise our strategy and business plans or could be required, or elect,
to seek additional funding through public or private equity or debt financings;
however, such funding may not be available on terms acceptable to us, if at all.

delays in our ongoing capital projects or substantial cost increases, including
construction costs and related materials costs, related to their execution could
significantly impact our ability to maximize our revenue opportunities and
adversely impact our business and cash flows.

Debt and Other Long-Term Obligations



Convertible Notes: In March 2021, we issued $690.0 million aggregate principal
amount of 0.25% unsecured green convertible senior notes that mature, unless
earlier converted, redeemed or repurchased, on April 1, 2026 (the "Convertible
Notes"), at a price of par. Interest on the Convertible Notes is payable on
April 1st and October 1st of each year, beginning on October 1, 2021.

The Convertible Notes are convertible into shares of the Company's common stock
at an initial conversion price of $44.28 per share, or 22.5861 shares, per
$1,000 principal amount of notes, subject to adjustment upon the occurrence of
certain corporate events. However, in no event will the conversion price exceed
28.5714 shares of common stock per $1,000 principal amount of notes.

We aim to allocate an amount equal to the net proceeds from the Convertible
Notes offering to existing or future investments in, or the financing or
refinancing of, eligible "green projects." Eligible green projects are intended
to reduce the Company's environmental impact and/or enable the production of
low-carbon technologies. Pending such allocation of the net proceeds to eligible
green projects, we intend to use the net proceeds from the Convertible Notes
offering for general corporate purposes.

Offtake Advances: In March 2022, the Company made a $2.9 million payment to
Shenghe pursuant to an obligation under the A&R Offtake Agreement to pay
Shenghe, on an annual basis, an amount equal to our annual net income, less any
amounts recouped through the Gross Profit Recoupment mechanism over the course
of the year, until the Prepaid Balance was reduced to zero (terms as discussed
and defined in   Note 3, "Relationship and Agreements with Shenghe,"   in the
notes to the unaudited Condensed Consolidated Financial Statements).

Upon payment by the Company, the Prepaid Balance was repaid in full, and the A&R
Offtake Agreement was terminated. Prior to full repayment, the debt to Shenghe
was satisfied primarily through product sales, where partial non-cash
consideration was received by the Company in the form of debt reduction
(generally equal to approximately 15% of the ultimate market value of the REO,
excluding tariffs, duties and certain other charges).

Equipment Notes: We have entered into several financing agreements for the
purchase of equipment, including trucks, tractors, loaders, graders, and various
other machinery. As of March 31, 2022, we had $9.0 million in principal (and
accrued interest) outstanding under the equipment notes.

Net Cash Provided by Operating Activities: Net cash provided by operating
activities increased by $111.6 million for the three months ended March 31,
2022, as compared to the prior year period, reflecting the increase in product
sales and a net increase due to the timing of receipt or payment of working
capital items, such as accounts receivable and accounts payable, partially
offset by the increase in our cost of sales and selling, general and
administrative expenses. In addition, $13.6 million of our product sales was
excluded from cash provided by operating activities for the three months ended
March 31, 2022, since that portion of the sales price was retained by Shenghe to
reduce the debt obligation, compared to $11.3 million in the prior year period.

Net Cash Used in Investing Activities: Net cash used in investing activities
increased by $30.6 million for the three months ended March 31, 2022, compared

expenditures relating primarily to our Stage II optimization project and our
Fort Worth Facility, partially offset by $5.1 million of proceeds from a
government award used for construction, specifically our Stage II optimization
project.

Net Cash Provided by (Used in) Financing Activities: Net cash used in financing
activities was $17.9 million for the three months ended March 31, 2022, compared
to net cash provided by financing activities of $671.8 million in the prior year
period. The current year period consisted primarily of tax withholding on

while the prior year period consisted primarily of the net proceeds received
from the issuance of the Convertible Notes in March 2021 of $672.6 million.

Non-GAAP Financial Measures



We present Total Value Realized, Production Costs, Adjusted EBITDA, Adjusted Net
Income, Adjusted Diluted EPS, and Free Cash Flow, which are non-GAAP financial
measures that we use to supplement our results presented in accordance with
GAAP. These measures may be similar to measures reported by other companies in
our industry and are regularly used by securities analysts and investors to
measure companies' financial performance. Total Value Realized, Production
Costs, Adjusted EBITDA, Adjusted Net Income, Adjusted Diluted EPS, and Free Cash
Flow are not intended to be a substitute for any GAAP financial measure and, as
calculated, may not be comparable to other similarly titled measures of
performance or liquidity of other companies within our industry or in other

Adjusted EBITDA



We calculate Adjusted EBITDA as our GAAP net income before interest expense,
net; income tax expense or benefit; and depreciation, depletion and
amortization; further adjusted to eliminate the impact of stock-based
compensation expense; transaction-related, start-up and other non-recurring
costs; accretion of asset retirement and environmental obligations; gain or loss
on sale or disposal of long-lived assets; tariff rebates; and other income, net.
We present Adjusted EBITDA because it is used by management to evaluate our
underlying operating and financial performance and trends. Adjusted EBITDA
excludes certain expenses that are required in accordance with GAAP because they
are non-recurring, non-cash or are not related to our underlying business
performance. This non-GAAP financial measure is intended to supplement our GAAP
results and should not be used as a substitute for financial measures presented
in accordance with GAAP.

other non-recurring costs; gain or loss on sale or disposal of long-lived
assets; tariff rebates; and other income or loss, net; adjusted to give effect
to the income tax impact of such adjustments. We calculate Adjusted Diluted EPS
as our GAAP diluted earnings per share ("EPS") excluding the per share impact,
using GAAP diluted weighted-average shares outstanding as the denominator, of
depletion; stock-based compensation expense; transaction-related, start-up and
other non-recurring costs; gain or loss on sale or disposal of long-lived
assets; tariff rebates; and other income or loss, net; adjusted to give effect
to the income tax impact of such adjustments.

To calculate the income tax impact of such adjustments on a year-to-date basis,
we utilize an effective tax rate equal to our income tax expense excluding
material discrete costs and benefits, with any impacts of changes in effective
tax rate being recognized in the current period. We present Adjusted Net Income
and Adjusted Diluted EPS because it is used by management to evaluate our
underlying operating and financial performance and trends.

Adjusted Net Income and Adjusted Diluted EPS exclude certain expenses that are
required in accordance with GAAP because they are non-recurring, non-cash, or
not related to our underlying business performance. As a result of the
acquisition of Secure Natural Resources LLC, the mineral rights for the rare
earth ores contained in our mine were recorded at fair value, resulting in a
significant step-up of the carrying amount of the asset which caused depletion
to be meaningfully higher than prior periods. While the depletion expense
related to the stepped-up mineral rights asset is excluded from Adjusted Net
Income and Adjusted Diluted EPS, the revenue related to such mineral rights is
reflected in Adjusted Net Income and Adjusted Diluted EPS as this asset
contributes to our revenue generation. These non-GAAP financial measures are
intended to supplement our GAAP results and should not be used as a substitute
for financial measures presented in accordance with GAAP.

The following table presents a reconciliation of our Adjusted Net Income, which is a non-GAAP financial measure, to our net income, which is determined in accordance with GAAP:

Free Cash Flow



We calculate Free Cash Flow as net cash provided by operating activities less
additions of property, plant and equipment, net of proceeds received from
government awards used for construction. We believe Free Cash Flow is useful for
comparing our ability to generate cash with that of our peers. The presentation
of Free Cash Flow is not meant to be considered in isolation or as an
alternative to cash flows from operating activities and does not necessarily
indicate whether cash flows will be sufficient to fund cash needs.

The following table presents a reconciliation of our Free Cash Flow, which is a
non-GAAP financial measure, to our net cash provided by operating activities,
which is determined in accordance with GAAP:

                                                                   For the three months ended March

(1)Under the terms of the A&R Offtake Agreement and pursuant to the accounting
treatment thereof, $13.6 million and $11.3 million of our product sales for the
three months ended March 31, 2022 and 2021, respectively, were excluded from
cash provided by operating activities since that portion of the sales price was
retained by Shenghe to reduce the debt obligation.

(2)Amount for the three months ended March 31, 2022, is net of $5.1 million in
proceeds received from a government award used for construction, specifically
our Stage II optimization project.
