CAUTIONARY NOTE REGARDING FORWARD LOOKING STATEMENTS

This report includes statements of our expectations, intentions, plans and beliefs that constitute “forward-looking statements.” These statements, which involve risks and uncertainties, relate to analyses and other information that are based on forecasts of future results and estimates of amounts not yet determinable and may also relate to our future prospects, developments and business strategies. We have used the words “anticipate,” “believe,” “could,” “estimate,” “expect,” “intend,” “may,” “plan,” “predict,” “project,” “should” and similar terms and phrases, including references to assumptions, in this report to identify forward-looking statements. These forward-looking statements are made based on expectations and beliefs concerning future events affecting us and are subject to uncertainties and factors relating to our operations and business environment, all of which are difficult to predict and many of which are beyond our control, that could cause our actual results to differ materially from those matters expressed in or implied by these forward-looking statements.

The following factors are among those that may cause actual results to differ materially from our forward-looking statements:

the effects of the COVID-19 pandemic on our operations and the world economy;
the financial performance of the company;
our liquidity, results of operations and financial condition;
our ability to generate sufficient cash or obtain financing to fund our business operations;
depressed levels or declines in coal prices;
worldwide market demand for coal, steel, and electricity, including demand for U.S. coal exports, and competition in coal markets;
our ability to obtain financing and other services, and the form and degree of these services available to us, which may be significantly limited by the lending, investment and similar policies of financial institutions and insurance companies regarding carbon energy producers and the environmental impacts of coal combustion;
our ability to meet collateral requirements;
the imposition or continuation of barriers to trade, such as tariffs;
utilities switching to alternative energy sources such as natural gas, renewables and coal from basins where we do not operate;
reductions or increases in customer coal inventories and the timing of those changes;
our production capabilities and costs;
inherent risks of coal mining beyond our control;
changes in, interpretations of, or implementations of domestic or international tax or other laws and regulations, including the Tax Cuts and Jobs Act and its related regulations;
changes in domestic or international environmental laws and regulations, and court decisions, including those directly affecting our coal mining and production, and those affecting our customers’ coal usage, including potential climate change initiatives;
our relationships with, and other conditions affecting, our customers, including the inability to collect payments from our customers if their creditworthiness declines;
changes in, renewal or acquisition of, terms of and performance of customers under coal supply arrangements and the refusal by our customers to receive coal under agreed-upon contract terms;
our ability to obtain, maintain or renew any necessary permits or rights, and our ability to mine properties due to defects in title on leasehold interests;
attracting and retaining key personnel and other employee workforce factors, such as labor relations;
funding for and changes in employee benefit obligations;
any new or increased liabilities, including reclamation obligations, that we may incur in connection with our former mines in Wyoming;
cybersecurity attacks or failures, threats to physical security, extreme weather conditions or other natural disasters;
reclamation and mine closure obligations;
our assumptions concerning economically recoverable coal reserve estimates;
our ability to negotiate new United Mine Workers of America wage agreements on terms acceptable to us, increased unionization of our workforce in the future, and any strikes by our workforce;
disruptions in delivery or changes in pricing from third-party vendors of key equipment and materials that are necessary for our operations, such as diesel fuel, steel products, explosives, tires and purchased coal;
inflationary pressures on supplies and labor and significant or rapid increases in commodity prices;
railroad, barge, truck and other transportation availability, performance and costs;
disruption in third-party coal supplies;
the consummation of financing or refinancing transactions, acquisitions or dispositions and the related effects on our business and financial position;
