Cautionary Notice Regarding Forward-Looking Statements



This report contains "forward-looking statements" - that is, statements related
to future, not past, events. In this context, forward-looking statements often
address our expected future business and financial performance, and often
contain words such as "should," "appears," "expects," "anticipates," "intends,"
"plans," "believes," "seeks," or "will." Forward-looking statements by their
nature address matters that are, to different degrees, uncertain. For us,
particular uncertainties arise from the COVID-19 pandemic, including its adverse
effects on businesses, economies, and financial markets worldwide; from the
impact of COVID-19 on efficiency, costs and production; from changes in the
demand for our coal by the steel production and electricity generation
industries; from our ability to access the capital markets on acceptable terms
and conditions; from policy, legislation and regulations relating to the Clean
Air Act, greenhouse gas emissions, incentives for alternative energy sources,
and other environmental initiatives; from competition within our industry and
with producers of competing energy sources; from our ability to successfully
acquire or develop coal reserves, including the integration of our Leer South
mine and its ramp up to full production levels; from operational, geological,
permit, labor, transportation, and weather-related factors; from the effects of
foreign and domestic trade policies, actions or disputes; from fluctuations in
the amount of cash we generate from operations, which could impact, among other
things, our ability to service our outstanding indebtedness and fund capital
expenditures; from our ability to successfully integrate the operations that we
acquire; from our ability to generate significant revenue to make payments
required by, and to comply with restrictions related to, our indebtedness,
including our ability to repurchase our Convertible Notes; from additional
demands for credit support by third parties; from the loss of, or significant
reduction in, purchases by our largest customers; from the development of future
technology to replace coal with hydrogen in the steelmaking process; and from
numerous other matters of national, regional and global scale, including those
of a political, economic, business, competitive or regulatory nature. These
uncertainties may cause our actual future results to be materially different
than those expressed in our forward-looking statements. We do not undertake to
update our forward-looking statements, whether as a result of new information,
future events or otherwise, except as may be required by law. For a description
of some of the risks and uncertainties that may affect our future results, you
should see the "Risk Factors" in Item 1A of our Annual Report on Form 10-K for
the year ended December 31, 2020 and subsequent Form 10-Q filings.

COVID-19



In the first quarter of 2020, COVID-19 emerged as a global pandemic. The
continuing responses to the COVID-19 outbreak include actions that have a
significant impact on domestic and global economies, including travel
restrictions, gathering bans, stay at home orders, and many other restrictive
measures. All of our operations have been classified as essential in the states
in which we operate. We instituted many policies and procedures, in alignment
with CDC guidelines along with state and local mandates, to protect our
employees during the COVID-19 outbreak. These policies and procedures included,
but were not limited to, staggering shift times to limit the number of people in
common areas at one time, limiting meetings and meeting sizes, continual
cleaning and disinfecting of high touch and high traffic areas, including door
handles, bathrooms, bathhouses, access elevators, mining equipment, and other
areas, limiting contractor access to our properties, limiting business travel,
and instituting work from home for administrative employees. During the third
quarter of 2021, vaccination rates among our workforce began to level off in
alignment with national and local trends. Furthermore, with the advent of the
Delta variant, infection rates among our workforce increased at certain
operations, in alignment with national and local trends, and we reinstated
stricter protocols at these operations. During the third quarter of 2021, over
thirty unit production shifts in our metallurgical segment were adversely
impacted by staffing shortfalls related to increased COVID-19 case rates, and
our requisite quarantine protocols. We continue to encourage vaccination among
our workforce and adjust our COVID-19 responses. We continually evaluate our
policies and procedures, in accordance with CDC, state, and local guidelines,
and make any necessary adjustments to respond to the particular circumstances in
the areas in which we operate.

We recognize that the COVID-19 outbreak and responses thereto also continue to
impact both our customers and suppliers. To date, we have not had any
significant issues with critical suppliers, and we continue to communicate with
them and closely monitor their developments to ensure we have access to the
goods and services required to maintain our operations. Our customers have
reacted, and continue to react, in various ways and to varying degrees to
changes in demand for their products. Our current view of our customer demand
situation is discussed in greater detail in the "Overview" section below.

Overview



Our results for the third quarter of 2021 benefited from continued improvement
in metallurgical and thermal coal markets. During the third quarter of 2021,
global economic growth continued to accelerate as pent up demand from the
responses to the global pandemic seeks to be fulfilled. Global steel production
appears to currently exceed pre-pandemic levels. At the same time, increased
COVID-19 cases in certain coal producing jurisdictions, particularly Mongolia,
have constrained coking coal supply, and a wetter than normal rainy season in
Indonesia, has constrained thermal coal supply. Furthermore, global supply chain
constraints, COVID-19 related and otherwise, have restricted hydrocarbon
supplies across the energy sector. Through the third quarter of 2021, supply
chain constraints have had a relatively minor impact on our shipment volumes,
although we did have two coking coal vessels that we planned to ship late in the
third quarter, delayed to early in the fourth quarter. If rail or vessel supply
chain constraints increased in our areas of operation, our future results could
be negatively impacted.

During the third quarter of 2021, accelerating global economic growth,
historically high steel prices, and production and supply chain constraints,
combined to drive international coking coal indices to historically high levels.
Despite historically high coking coal prices, North American coking coal supply
remains constrained compared to pre-COVID-19 levels. Some new supplies have been
added to the market, in particular, our new Leer South longwall operation that
will be ramping up production throughout the fourth quarter of 2021. Still, some
of the high cost coking coal mine idlings announced during 2020 remain in place,
and more recent supply disruptions also constrain supply. The duration of
specific supply disruptions is unknown. We believe that under investment in the
sector in recent years underlies the current market situation. In the current
environment, we expect coking coal prices to be volatile. Longer term, we
believe continued limited global capital investment in new coking coal
production capacity, normal reserve depletion, and continuing economic growth
will provide support to coking coal markets.

During the fourth quarter of 2020, a major political dispute that manifested
itself as a trade dispute escalated between China, a major importer of coking
coal, and Australia, the world's largest exporter of coking coal. Specifically,
China has effectively banned the import of coking coal and thermal coal, among
other export products, from Australia. Historical trade patterns remain
disrupted, and new trade patterns have emerged in the international coking coal
markets. Indices for United States (US) East Coast coking coal continued to
increase during the third quarter of 2021, as strong demand, particularly from
China, has had a positive impact on these markets. Australian Premium Low
Volatile ("PLV") coking coal indices have also increased to historic levels as
demand outside of China has increased though Australian export volumes remain
below pre-pandemic levels. Recently, China has announced plans to reduce steel
production. This planned reduction has not yet impacted coking coal prices, but
depending on the magnitude of the reduction, could put pressure on all
international coking coal indices.

Domestic thermal coal consumption increased in the third quarter of 2021,
compared to the third quarter of 2020, due to significantly increased natural
gas prices and continuing economic recovery from the responses to COVID-19.
Longer term, we continue to believe thermal coal demand will remain pressured by
continuing increases in subsidized renewable generation sources, particularly
wind and solar, and planned retirements of coal fueled generating facilities.
Currently, however; the significant increase in natural gas prices has led to an
increase in coal fired generation. We believe coal generator stockpiles likely
declined significantly during the current quarter, and domestic thermal coal
indices have reached historically high levels. Importantly, this increase in
domestic prices has allowed us to place significant volumes of domestic term
business at prices meaningfully higher than seen prior to the third quarter of
2021. During the third quarter of 2021, international thermal coal market
pricing increased to historical highs that economically support exports from our
thermal operations. We continue to layer in additional thermal export
commitments for the current year and 2022.

On September 29, 2020, the U.S. District Court ruled against our proposal with
Peabody to form a joint venture that would have combined our Powder River Basin
and Colorado mining operations with Peabody's, and we subsequently announced the
termination of our joint venture efforts. We continue to pursue other strategic
alternatives for our thermal assets, including, among other things, potential
divestiture. We are concurrently shrinking our operational footprint at our
thermal operations. During the first nine months of 2021, we have completed
approximately $32.2 million of Asset Retirement Obligation (ARO) work at these
operations, compared to approximately $4.5 million in the first nine months of
2020. We are also planning to establish self-funding mechanisms for these
long-term reclamation liabilities at those operations. Currently, we will
exercise our operational flexibility to maximize cash generation from our
thermal operations. Longer term, we will maintain our focus on aligning our
thermal production rates with the secular decline in domestic thermal coal
demand, while adjusting our thermal operating plans to minimize future cash
requirements and maintain flexibility to react to future short-term market
fluctuations. We continue to streamline our entire organizational structure to
reflect our long-term strategic direction as a leading producer of metallurgical
products for the steelmaking industry.

while tons sold increased approximately 3.9 million tons, or 22.6%. Coal sales
from Metallurgical operations increased approximately $127.2 million, primarily
due to increased pricing. Thermal coal sales increased approximately $85.8
million due to increased pricing and volume. In the prior year quarter, our
Viper operation, which was sold in December 2020, provided approximately $10.0
million in coal sales and 0.3 million tons sold. See the discussion in
"Operational Performance" for further information about segment results.

Cost of sales. Our cost of sales for the third quarter of 2021 increased
approximately $78.3 million, or 22.7%, versus the third quarter of 2020. In the
prior year quarter, our Viper operation, which was sold in December 2020,
accounted for approximately $11.8 million in cost of sales. The increase in cost
of sales at ongoing operations consists of increased transportation costs of
approximately $30.9 million, increased repairs and supplies costs of
approximately $28.0 million, increased operating taxes and royalties resulting
from higher sales prices of approximately $22.9 million, and increased
compensation costs of approximately $10.7 million. These cost increases were
partially offset by an increase in credit for ARO reclamation work completed
primarily at our Thermal operations of approximately $4.1 million. See
discussion in "Operational Performance" for further information about segment
results.


Depreciation, depletion, and amortization. The decrease in depreciation, depletion, and amortization in the third quarter of 2021 versus the third quarter of 2020 is primarily due to the reduced depreciation expense of approximately $2.7 million resulting from the asset impairment we recorded in the third quarter of 2020 in our Thermal segment.





Accretion on asset retirement obligations. The increase in accretion expense in
the third quarter of 2021 versus the third quarter of 2020 is primarily related
to the changes in the planned timing of reclamation work to be completed at our
Thermal operations, specifically at the Coal Creek mine.

Change in fair value of coal derivatives and coal trading activities, net. The
costs in both the third quarter of 2021 and 2020 are primarily related to
mark-to-market losses on coal derivatives that we had entered to hedge our price
risk for planned international thermal coal shipments.

Selling, general and administrative expenses. Selling, general and
administrative expenses in the third quarter of 2021 decreased versus the third
quarter of 2020 due to reduced contractor services of approximately $1.6
million, partially offset by increased compensation costs of approximately $1.0
million, primarily related to higher incentive compensation accruals recorded in
the third quarter of 2021.

Costs related to proposed joint venture with Peabody Energy. We incurred expenses of $4.4 million in the third quarter of 2020 associated with the regulatory approval process related to the proposed joint venture with Peabody that was terminated jointly by the parties following the Federal Trade Commission's successful lawsuit to block the joint venture.



Asset impairment and restructuring. In the third quarter of 2020, we recorded
$163.1 million of impairment charges relating to three of our thermal
operations, Coal Creek, West Elk, and Viper, as well as, our equity investment
in Knight Hawk Holdings, LLC. For further information on our Asset Impairment
costs, see Note 5, "Asset Impairment and Restructuring" to the Condensed
Consolidated Financial Statements.

Other operating income, net. The decrease in other operating income, net in the
third quarter of 2021 versus the third quarter of 2020 consists primarily of the
net unfavorable impact of certain coal derivative settlements of approximately
$9.1 million, partially offset by increased income from equity investments

of
approximately $3.7 million.


Nonoperating expenses. The following table summarizes our nonoperating expenses during the three months ended September 30, 2021 and 2020:

Non-service related pension and postretirement benefit costs. The increase in non-service related pension and postretirement benefit costs in the third quarter of 2021 versus the third quarter of 2020 is primarily due to the increased postretirement benefit loss amortization in the third quarter of 2021.

Cost of sales. Our cost of sales for the first nine months of 2021 increased
approximately $52.2 million, or 5.0%, versus the first nine months of 2020. In
the prior year period, our Viper operation, which was sold in December 2020,
accounted for approximately $33.9 million in cost of sales. The increase in cost
of sales at ongoing operations consists of increased transportation costs of
approximately $56.2 million, increased operating taxes and royalties resulting
from higher sales prices of approximately $33.6 million, increased compensation
costs of approximately $15.8 million, and increased repairs and supplies costs
of approximately $14.7 million. These cost increases were partially offset by an
increase in credit for ARO reclamation work completed primarily at our Thermal
operations of approximately $26.3 million and a decrease in purchased coal costs
of approximately $12.5 million. See discussion in "Operational Performance" for
further information about segment results.

Depreciation, depletion, and amortization. The decrease in depreciation,
depletion, and amortization in the first nine months of 2021 versus the first
nine months of 2020 is primarily due to the reduced depreciation expense of
approximately $8.1 million resulting from the asset impairment we recorded in
the third quarter of 2020 in our Thermal segment.

Accretion on asset retirement obligations. The increase in accretion expense in
the first nine months of 2021 versus the first nine months of 2020 is primarily
related to the changes in the planned timing of reclamation work to be completed
at our Thermal operations, specifically at the Coal Creek mine.

Change in fair value of coal derivatives and coal trading activities, net. The
costs in both the first nine months of 2021 and 2020 are primarily related to
mark-to-market losses on coal derivatives that we had entered to hedge our price
risk for planned international thermal coal shipments.

Selling, general and administrative expenses. Selling, general and
administrative expenses in the first nine months of 2021 increased versus the
first nine months of 2020 due to increased compensation costs of approximately
$4.5 million, primarily related to higher incentive compensation accruals
recorded in the first nine months of 2021, partially offset by reduced IT
related costs of approximately $1.4 million.



Costs related to proposed joint venture with Peabody Energy. During the first
nine months of 2020, we incurred expenses of $15.9 million associated with the
regulatory approval process related to the proposed joint venture with Peabody
that was terminated jointly by the parties following the Federal Trade
Commission's successful lawsuit to block the joint venture.

Asset impairment and restructuring. During the first nine months of 2020, we
recorded $163.1 million of impairment charges relating to three of our thermal
operations, Coal Creek, West Elk, and Viper, as well as, our equity investment
in Knight Hawk Holdings, LLC. Also, during the first nine months of 2020, we
recorded $13.3 million of employee severance expense related to voluntary
separation plans that were accepted by 53 employees of the corporate staff and
201 employees of our Thermal operations. For further information on our Asset
Impairment costs, see Note 5, "Asset Impairment and Restructuring" to the
Condensed Consolidated Financial Statements.

Gain on property insurance recovery related to Mountain Laurel longwall. During the first nine months of 2020, we recorded a $23.5 million benefit from insurance proceeds related to the loss of certain longwall shields at our Mountain Laurel operation.

Gain on divestitures. During the first nine months of 2020, we recorded a $1.4 million gain on the sale of our idle Dal-Tex and Briar Branch properties.


Other operating income, net. The decrease in other operating income, net in the
first nine months of 2021 versus the first nine months of 2020 consists
primarily of the net unfavorable impact of certain coal derivative settlements
of approximately $14.0 million, partially offset by increased income from equity
investments of approximately $5.9 million and an unfavorable impact of mark to
market movements on heating oil positions of approximately $2.0 million recorded
in the first nine months of 2020.

Operational Performance

Three and Nine Months Ended September 30, 2021 and 2020


On December 31, 2020, we sold our Viper operation. As a result, we revised our
reportable segments beginning in the first quarter of 2021 to better reflect the
manner in which the chief operating decision maker (CODM) views our businesses
going forward for purposes of reviewing performance, allocating resources and
assessing future prospects and strategic execution. Prior to the first quarter
of 2021, we had three reportable segments: MET, Powder River Basin (PRB), and
Other Thermal. After the divestment of Viper, we have three remaining active
thermal mines: West Elk, Black Thunder, and Coal Creek. With two distinct lines
of business, metallurgical and thermal, the movement to two segments better
aligns with how we make decisions and allocate resources. No changes were made
to the MET Segment and the three remaining thermal mines have been combined as
the "Thermal Segment". The prior periods have been restated to reflect the
change in reportable segments.

Our mining operations are evaluated based on Adjusted EBITDA, per-ton cash
operating costs (defined as including all mining costs except depreciation,
depletion, amortization, accretion on asset retirements obligations, and
pass-through transportation expenses, divided by segment tons sold), and on
other non-financial measures, such as safety and environmental performance.
Adjusted EBITDA is defined as net income (loss) attributable to us before the
effect of net interest expense, income taxes, depreciation, depletion and
amortization, the accretion on asset retirement obligations and nonoperating
expenses. Adjusted EBITDA may also be adjusted for items that may not reflect
the trend of future results by excluding transactions that are not indicative of
our core operating performance. Adjusted EBITDA is not a measure of financial
performance in accordance with generally accepted accounting principles, and
items excluded from Adjusted EBITDA are significant in understanding and
assessing our financial condition. Therefore, Adjusted EBITDA should not be
considered in isolation, nor as an alternative to net income (loss), income
(loss) from operations, cash flows from operations or as a measure of our
profitability, liquidity or performance under generally accepted accounting
principles. Furthermore, analogous measures are used by industry analysts and
investors to evaluate our operating performance. Investors should be aware that
our presentation of Adjusted EBITDA may not be comparable to similarly titled
measures used by other companies.

Metallurgical - Adjusted EBITDA for the three and nine months ended September
30, 2021 increased from the three and nine months ended September 30, 2020 due
to increased pricing and increased volume in the case of the nine month period.
These benefits were partially offset by increased cash cost of sales per ton
sold. The improvement in the current year periods over the prior year periods is
largely due to the difference in trajectory of the COVID-19 pandemic during the
respective periods in time. During the first nine months of 2021, increasing
vaccine availability and decreasing infection rates led to accelerating economic
growth, and increasing steel demand and pricing, improving prompt coking coal
index prices. In contrast, during the first nine months of 2020, coking coal
prices fell as large scale industrial shutdowns were initiated in response to
the emergence of COVID-19. Particularly, in the three months ended September 30,
2021, surging coking coal demand, largely from China, and constrained supply led
to historically high pricing across all coking coal indices. The increase in
cash cost per ton sold is largely due to increased taxes and royalties that are
based on a percentage of coal sales per ton sold.

During the end of the third quarter of 2021, we completed our Leer South
longwall development, and initiated longwall production in late August of 2021.
The ramp up is ongoing, and we expect to achieve planned productivity levels by
early 2022. The addition of this second longwall operation to our Metallurgical
Segment is expected to significantly increase our future volumes and strengthen
our low average segment cost structure relative to our peers.

Our Metallurgical segment sold 1.8 million tons of coking coal and 0.2 million
tons of associated thermal coal in the three months ended September 30, 2021,
compared to 1.7 million tons of coking coal and 0.3 million tons of associated
thermal coal in the three months ended September 30, 2020. In the nine months
ended September 30, 2021, we sold 5.1 million tons of coking coal and 0.6
million tons of associated thermal coal compared to 4.5 million tons of coking
coal and 0.7 million tons of associated thermal coal in the nine months ended
September 30, 2020. Longwall operations accounted for approximately 70% of our
shipment volume in the three and nine months ended September 30, 2021, compared
to approximately 60% of our shipment volume in the three and nine months ended
September 30, 2020.

Thermal - Adjusted EBITDA for the three and nine months ended September 30, 2021
increased versus the three and nine months ended September 30, 2020, due to
increased sales volume and decreased cash cost per ton sold, partially offset by
decreased coal sales per ton sold. The improvement in the current year periods
over the prior year periods is largely due to increased domestic utility coal
burn, resulting from higher natural gas pricing and improved economic growth.
The reduction in both coal sales per ton sold and cash cost per ton sold is
driven by the increased percentage of volume from our lower cost and lower
priced Black Thunder operation. Our cash cost per ton sold also benefited from
our operational flexibility to take advantage of increasing demand, despite the
substantial progress we have made in our efforts to align production levels with
the secular decline in domestic thermal coal demand. Also, contributing to the
decreases in cost and price is the inclusion of approximately 0.7 million tons
sold from our former Viper operation in the nine months ended September 30,
2020. During the first nine months of 2021, we completed approximately $32.2
million of ARO work at our current Thermal operations, compared to $4.5 million
during the first nine months of 2020.

Reconciliation of Non-GAAP measures

Segment coal sales per ton sold



Non-GAAP Segment coal sales per ton sold is calculated as segment coal sales
revenues divided by segment tons sold. Segment coal sales revenues are adjusted
for transportation costs, and may be adjusted for other items that, due to
generally accepted accounting principles, are classified in "other income" on
the statement of operations, but relate to price protection on the sale of coal.
Segment coal sales per ton sold is not a measure of financial performance in
accordance with generally accepted accounting principles. We believe segment
coal sales per ton sold provides useful information to investors as it better
reflects our revenue for the quality of coal sold and our operating results by
including all income from coal sales. The adjustments made to arrive at these
measures are significant in understanding and assessing our financial condition.
Therefore, segment coal sales revenues should not be considered in isolation,
nor as an alternative to coal sales revenues under generally accepted accounting
principles.

Segment cash cost per ton sold


Non-GAAP Segment cash cost per ton sold is calculated as segment cash cost of
coal sales divided by segment tons sold. Segment cash cost of coal sales is
adjusted for transportation costs, and may be adjusted for other items that, due
to generally accepted accounting principles, are classified in "other income" on
the statement of operations, but relate directly to the costs incurred to
produce coal. Segment cash cost per ton sold is not a measure of financial
performance in accordance with generally accepted accounting principles. We
believe segment cash cost per ton sold better reflects our controllable costs
and our operating results by including all costs incurred to produce coal. The
adjustments made to arrive at these measures are significant in understanding
and assessing our financial condition. Therefore, segment cash cost of coal
sales should not be considered in isolation, nor as an alternative to cost of
sales under generally accepted accounting principles.

Reconciliation of Segment Adjusted EBITDA to Net Income (Loss)


The discussion in "Results of Operations" above includes references to our
Adjusted EBITDA for each of our reportable segments. Adjusted EBITDA is defined
as net income (loss) attributable to us before the effect of net interest
expense, income taxes, depreciation, depletion and amortization, the accretion
on asset retirement obligations and nonoperating expenses. Adjusted EBITDA may
also be adjusted for items that may not reflect the trend of future results by
excluding transactions that are not indicative of our core operating
performance. We use Adjusted EBITDA to measure the operating performance of our
segments and allocate resources to our segments. Adjusted EBITDA is not a
measure of financial performance in accordance with generally accepted
accounting principles, and items excluded from Adjusted EBITDA are significant
in understanding and assessing our financial condition. Therefore, Adjusted
EBITDA should not be considered in isolation, nor as an alternative to net
income (loss), income (loss) from operations, cash flows from operations or as a
measure of our profitability, liquidity or performance under generally accepted
accounting principles. Investors should be aware that our presentation of
Adjusted EBITDA may not be comparable to similarly titled measures used by other
companies. The table below shows how we calculate Adjusted EBITDA.

Liquidity and Capital Resources


Our primary sources of liquidity are proceeds from coal sales to customers and
certain financing arrangements. Excluding significant investing activity, we
intend to satisfy our working capital requirements and fund capital expenditures
and debt-service obligations with cash generated from operations and cash on
hand. As we continue to evaluate the impacts of COVID-19 and the responses
thereto on our business, we remain focused on prudently managing costs,
including capital expenditures, maintaining a strong balance sheet, and ensuring
adequate liquidity.

Given the volatile nature of coal markets, and the significant challenges and
uncertainty surrounding COVID-19, we believe it remains important to take a
prudent approach to managing our balance sheet and liquidity. Due to the current
economic uncertainties related to COVID-19 and the related disruption in the
financial markets, we may be limited in accessing capital markets or obtaining
additional bank financing, or the cost of accessing this financing could become
more expensive. We believe our current liquidity level is sufficient to fund our
business, and given the completion of our Leer South development and current
favorable pricing environment, we expect our liquidity to grow in the near term.
With the improvement in liquidity, we plan to begin funding a sinking fund for
our long-term reclamation liabilities at our thermal operations in the Powder
River Basin, and have committed to make contributions of $15 million in the
fourth quarter of 2021 and $30 million in 2022. If cashflows are supportive, we
will also make contributions above those minimum amounts. Additionally, we are
reinstating our quarterly dividend, and will pay a $0.25 per share quarterly
dividend in the fourth quarter of 2021. In the near term, our financial
priorities will be to increase liquidity and reduce debt and other obligations.
Moving forward, we will continue to evaluate our capital allocation initiatives
in light of the current state of, and our outlook for coal markets, the amount
of our planned production that has been committed and priced, the capital needs
of the business, other strategic opportunities, and developments in the COVID-19
outbreak and the responses thereto.

On March 7, 2017, we entered into a senior secured term loan credit agreement in
an aggregate principal amount of $300 million (the "Term Loan Debt Facility")
with Credit Suisse AG, Cayman Islands Branch, as administrative agent and
collateral agent and the other financial institutions from time to time party
thereto. The Term Loan Debt Facility was issued at 99.50% of the face amount and
will mature on March 7, 2024. The term loans provided under the Term Loan Debt
Facility (the "Term Loans") are subject to quarterly principal amortization
payments in an amount equal to $750,000. Proceeds from the Term Loan Debt
Facility were used to repay all outstanding obligations under our previously
existing term loan credit agreement, dated as of October 5, 2016. The interest
rate on the Term Loan is, at our option, either (i) the London interbank offered
rate ("LIBOR") plus an applicable margin of 2.75%, subject to a 1.00% LIBOR
floor, or (ii) a base rate plus an applicable margin of 1.75%. For further
information regarding the Term Loan Debt Facility, see Note 11, "Debt and
Financing Arrangements" to the Condensed Consolidated Financial Statements.

We have entered into a series of interest rate swaps to fix a portion of the
LIBOR interest payments due under the Term Loans. As interest payments are made
on the Term Loans, amounts in accumulated other comprehensive income will be
reclassified into earnings through interest expense to reflect a net interest on
the Term Loans equal to the effective yield of the fixed rate of the swap plus
2.75%, which is the spread on the Term Loans as amended. For further information
regarding the interest rate swaps, see Note 11, "Debt and Financing
Arrangements" to the Condensed Consolidated Financial Statements.

On September 30, 2020, we extended and amended our existing trade accounts
receivable securitization facility provided to Arch Receivable Company, LLC, a
special-purpose entity that is a wholly owned subsidiary of Arch Resources
("Arch Receivable") (the "Securitization Facility"), which supports the issuance
of letters of credit and requests for cash advances. The amendment to the
Securitization Facility reduced the facility size from $160 million to $110
million and extended the maturity date to September 29, 2023. For further
information regarding the Securitization Facility see Note 11, "Debt and
Financing Arrangements" to the Condensed Consolidated Financial Statements.

On September 30, 2020, we amended the senior secured inventory-based revolving
credit facility in an aggregate principal amount of $50 million (the "Inventory
Facility") with Regions Bank ("Regions") as administrative agent and collateral
agent, as lender and swingline lender (in such capacities, the "Lender") and as
letter of credit issuer. Availability under the Inventory Facility is subject to
a borrowing base consisting of (i) 85% of the net orderly liquidation value of
eligible coal inventory, plus (ii) the lesser of (x) 85% of the net orderly
liquidation value of eligible parts and supplies inventory and (y) 35% of the
amount determined pursuant to clause (i), plus (iii) 100% of our Eligible

Cash (defined in the Inventory Facility), subject to reduction for reserves
imposed by Regions. The amendment of the Inventory Facility extended the
maturity date to September 29, 2023, eliminated the provision that accelerated
maturity of the facility upon falling below a specified level of liquidity, and
reduced the minimum liquidity requirement from $175 million to $100 million.
Additionally, the amendment includes provisions that reduce the advance rates
for coal inventory and parts and supplies, depending on liquidity. During the
second quarter of 2021, we entered into an amendment to temporarily suspend
certain of the Liquidity requirements within the existing facility through the
filing of the September 2021 borrowing base. For further information regarding
the Inventory Facility, see Note 11, "Debt and Financing Arrangements" to the
Condensed Consolidated Financial Statements.

On July 2, 2020, the West Virginia Economic Development Authority (the "Issuer")
issued $53.1 million aggregate principal amount of Solid Waste Disposal Facility
Revenue Bonds (Arch Resources Project), Series 2020 (the "Tax Exempt Bonds")
pursuant to an Indenture of Trust dated as of June 1, 2020 (the "Indenture of
Trust") between the Issuer and Citibank, N.A., as trustee (the "Trustee"). As a
follow-on to our $53.1 million offering, on March 4, 2021, the Issuer issued an
additional $45.0 million in Series 2021 Tax Exempt Bonds. The proceeds of the
Tax Exempt Bonds are loaned to us as we make qualifying expenditures pursuant to
a Loan Agreement dated as of June 1, 2020, as supplemented by a First Amendment
to the Loan Agreement dated March 1, 2021 (collectively, the "Loan Agreement"),
each between the Issuer and us. The Tax Exempt Bonds are payable solely from
payments to be made by us under the Loan Agreement as evidenced by a Note from
us to the Trustee. The proceeds of the Tax Exempt Bonds were used to finance
certain costs of the acquisition, construction, reconstruction, and equipping of
solid waste disposal facilities at our Leer South development, and for
capitalized interest and certain costs related to the issuance of the Tax Exempt
Bonds. As of September 30, 2021, the Company has utilized the total Tax Exempt
Bond proceeds. For further information regarding the Tax Exempt Bonds, see Note
11, "Debt and Financing Arrangements" to the Condensed Consolidated Financial
Statements.

In November, 2020, we issued $155.3 million in aggregate principal amount
of 5.25% convertible senior notes due 2025 ("Convertible Notes" or "Convertible
Debt"). The net proceeds from the issuance of the Convertible Notes, after
deducting offering related costs of $5.1 million and the cost of a capped call
transaction of $17.5 million, were approximately $132.7 million. The Convertible
Notes bear interest at the annual rate of 5.25%, payable semiannually in arrears
on May 15 and November 15 of each year, and will mature on November 15, 2025,
unless earlier converted, redeemed or repurchased by us. For further information
regarding the Convertible Debt, see Note 11, "Debt and Financing Arrangements"
to the Condensed Consolidated Financial Statements.



During the third quarter of 2021, the common stock price condition of the
Convertible Notes was satisfied, as the closing stock price exceeded 130% of the
conversion price of approximately $37.325 for at least 20 trading days of the
last 30 trading days prior to quarter end. As a result, the Convertible Notes
are convertible at the election of the noteholders during the fourth quarter,
and due to our stated intent to settle the principal value in cash, the
liability portion of $120.0 million of the Convertible Notes was included in
current maturities of debt on our Condensed Consolidated Balance Sheet at
September 30, 2021. As of the date of this Quarterly Report on Form 10-Q, we
have not received any conversion requests for the Convertible Notes and do not
anticipate receiving any conversion requests as the market value of the
Convertible Notes exceeds the conversion value of the Convertible Notes. As of
September 30, 2021, the if-converted value of the Convertible Notes exceeded the
principal amount by $230.5 million. For further information regarding the
Convertible Notes and the capped call transactions, see Note 11, "Debt and
Financing Arrangements" to the Condensed Consolidated Financial Statements.



On July 29, 2021, we entered into an equipment financing arrangement accounted
for as debt. We received $23.5 million in exchange for conveying an interest in
certain equipment in operation at our Powder River Basin operations and entered
into a master lease arrangement for that equipment. The financing arrangement
contains customary terms and events of default and provides for 42 monthly
payments with an average implied interest rate of 7.35% maturing on February 1,
2025. Upon maturity, we will have the option to purchase the equipment. For
further information regarding the Equipment Financing, see Note 11, "Debt and
Financing Arrangements" to the Condensed Consolidated Financial Statements.

On April 27, 2017, our Board of Directors authorized a capital return program
consisting of a share repurchase program and a quarterly cash dividend. The
share repurchase plan has a total authorization of $1.05 billion, of which we
have used $827.4 million. During the three months ended September 30, 2021, we
did not repurchase any shares of our

stock. The timing and amount of any future share purchases and the ultimate
number of shares to be purchased will depend on a number of factors, including
business and market conditions, our future financial performance, and other
capital priorities. Any shares acquired would be in the open market or through
private transactions in accordance with Securities and Exchange Commission
requirements. On April 23, 2020, we announced the suspension of our quarterly
dividend due to the significant economic uncertainty surrounding the COVID-19
pandemic and the steps being taken to control the virus. During the three months
ended September 30, 2021, we did not pay any dividends on shares of our stock.
On October 26, 2021, we announced the initiation of a $0.25 per share quarterly
dividend. The first dividend payment will be made to shareholders of record as
of November 30, 2021, payable on December 15, 2021.

On September 30, 2021, we had total liquidity of approximately $254 million,
including $210 million in unrestricted cash and equivalents and short-term
investments in debt securities, with the remainder provided by availability
under our credit facilities and funds withdrawable from brokerage accounts. The

The above standby letters of credit outstanding have primarily been issued to
satisfy certain insurance-related collateral requirements. The amount of
collateral required by counterparties is based on their assessment of our
ability to satisfy our obligations and may change at the time of policy renewal
or based on a change in their assessment. Future increases in the amount of
collateral required by counterparties would reduce our available liquidity.

Cash Flow

Cash provided by operating activities increased in the nine months ended
September 30, 2021 versus the nine months ended September 30, 2020 mainly due to
the improvement in results from operations discussed in the "Overview" and
"Operational Performance" sections above, partially offset by a greater increase
in working capital requirements of approximately $117 million in the current
year period, primarily in receivables; receipt of an approximately $38 million
income tax refund in the prior year period; and an increase in reclamation work
completed of approximately $26 million in the current year period.

Cash used in investing activities increased in the nine months ended September
30, 2021 versus the nine months ended September 30, 2020 primarily due to the
approximately $24 million in property insurance proceeds received on our
Mountain Laurel longwall claim in the nine months ended September 30, 2020, and
approximately $6 million in increased capital spending in the nine months ended
September 30, 2021, partially offset by a net increase in proceeds from sale of
short term investments in the nine months ended September 30, 2021 of
approximately $10 million.

Cash provided by financing activities decreased in the nine months ended September 30, 2021 compared to the nine months ended September 30, 2020 primarily due to a net decrease in proceeds from Equipment Financing transactions of

approximately $34 million and a net decrease in proceeds from the issuance of
our Tax Exempt Bonds of approximately $8 million, partially offset by a dividend
payment of approximately $8 million in the first nine months of 2020.
