PART I

Item 1.  Business.

Overview

We are one of the largest producers of coal in the United States of America (“U.S.”) and the PRB, based on our 2017 coal sales.  We operate some of the safest mines in the coal industry.  According to the most current MSHA data, we have one of the lowest employee all injury incident rates among the largest U.S. coal producing companies.  We currently operate solely in the PRB, the lowest cost region of the major coal producing regions in the U.S., where we own and operate three surface coal mines: the Antelope Mine, the Cordero Rojo Mine, and the Spring Creek Mine.

Our Antelope Mine and Cordero Rojo Mine are located in Wyoming and our Spring Creek Mine is located in Montana.  Our mines produce subbituminous thermal coal with low sulfur content, and we sell our coal primarily to domestic and foreign electric utilities.  Thermal coal is primarily consumed by electric utilities and industrial consumers as fuel for electricity generation.  In 2017, the coal we produced generated approximately 2% of the electricity produced in the U.S.  As of December 31, 2017, we controlled approximately 1.0 billion tons of proven and probable reserves.  We do not produce any metallurgical coal.  See Item 1. “Business—Mining Operations.”

In addition, we have two development projects, both located in the Northern PRB.  The Youngs Creek project is an undeveloped surface mine project located in Wyoming, seven miles south of our Spring Creek Mine and contiguous with the Wyoming-Montana state line.  The Big Metal project is located near the Youngs Creek project on the Crow Indian Reservation in southeast Montana.  These two projects are described in more detail under Item 1. “Business—Development Projects.”

Our logistics business provides a variety of services designed to facilitate the sale and delivery of coal.  These services include the purchase of coal from third parties or from our owned and operated mines, coordination of the transportation and delivery of purchased coal, negotiation of take-or-pay rail agreements and take-or-pay port agreements and demurrage settlement with vessel operators.  See Item 1. “Business—Transportation and Logistics Services” for further discussion.

Segment Information

Our reportable segments include Owned and Operated Mines and Logistics and Related Activities.  For a discussion on these segments, please see Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations as well as Note 21 of Notes to Consolidated Financial Statements in Item 8.

History

CPE Inc., a Delaware corporation organized on July 31, 2008, is a holding company that manages its 100% owned consolidated subsidiary CPE Resources, but has no business operations or material assets other than its ownership interest in CPE Resources.  CPE Inc.’s only source of cash flow from operations is distributions from CPE Resources pursuant to the CPE Resources limited liability company agreement.  CPE Inc. also receives management fees pursuant to a management services agreement between CPE Inc. and CPE Resources as reimbursement of certain administrative expenses.  Our business operations are conducted by CPE Resources, a Delaware limited liability company formed on August 19, 2008.  Between 1993 and 1998, our predecessor acquired the Antelope Mine, Spring Creek Mine, the Cordero Rojo Mine, and a 50% non-operating interest in the Decker Mine.  On September 12, 2014, we sold our 50% interest in the Decker Mine to an affiliate of Ambre Energy North America, Inc. (“Ambre Energy”), now known as Lighthouse Resources Inc.

CPE Inc. acquired approximately 51% and the managing member interest in CPE Resources in exchange for a promissory note, which was repaid with proceeds from the initial public offering of its common stock (“IPO”) on November 19, 2009.  Rio Tinto retained ownership of the remaining 49% interest in CPE Resources until December 15, 2010, when CPE Inc. priced a secondary offering of its common stock on behalf of Rio Tinto (the “Secondary Offering”).  In connection with the Secondary Offering, CPE Inc. exchanged shares of its common stock for common membership units of CPE Resources held by Rio Tinto, resulting in our acquisition of 100% of Rio Tinto’s holdings in CPE Resources.

Coal Characteristics

In general, coal of all geological compositions is characterized by end use either as thermal or metallurgical.  Heat value and sulfur content are the most important variables in the economic marketing and transportation of thermal coal.  We mine, process, and market low sulfur content, subbituminous thermal coal, the characteristics of which are described below.  Because we currently operate only in the PRB, which does not have metallurgical coal, we produce only thermal coal.

Heat Value

The heat value of coal is commonly measured in Btus.  Subbituminous coal from the PRB has a typical heat value that ranges from 8,000 to 9,500 Btus.  Subbituminous coal from the PRB is used primarily by electric utilities and by some industrial customers for steam generation.  Coal found in other regions in the U.S., including the eastern and Midwestern regions, tends to have a higher heat value than coal found in the PRB, other than lignite coal which has lower heat value than subbituminous coal but is typically only used to supply coal to utilities that are directly adjacent to the mine.

Sulfur Content

Federal and state environmental regulations, including regulations that limit the amount of sulfur dioxide that may be emitted as a result of combustion, have affected and may continue to affect the demand for certain types of coal.  See “Environmental and Other Regulatory Matters—Clean Air Act.”  The sulfur content of coal can vary from seam to seam and within a single seam.  The concentration of sulfur in coal affects the amount of sulfur dioxide produced in combustion.  Coal-fired power plants can comply with sulfur dioxide emissions regulations by burning coal with low sulfur content, blending coals with various sulfur contents, purchasing emission allowances on the open market and/or using sulfur-reduction technology, such as scrubbers, which can reduce sulfur dioxide emissions by up to 95% or more.

PRB coal typically has a lower sulfur content than eastern U.S. coal and generally emits no greater than 1.2 pounds of sulfur dioxide per million Btus.

Other

Ash is the inorganic residue remaining after the combustion of coal.  As with sulfur content, ash content varies from seam to seam.  Ash content is an important characteristic of coal because it impacts boiler performance and electric generating plants must handle and dispose of ash following combustion.  The ash content of PRB coal is generally low, representing approximately 5% to 10% by weight.  The composition of the ash, including the proportion of sodium oxide, as well as the ash fusion temperatures are important characteristics of coal and help determine the suitability of the coal to specific end users.  In limited cases, domestic customers at the Spring Creek Mine have required, and may continue to require, the addition of earthen materials to dilute the sodium oxide content of the post-combustion ash of the coal.

Moisture content of coal varies by the type of coal and the region where it is mined.  In general, high moisture content is associated with lower heat values and generally makes the coal more expensive to transport.  Moisture content in coal, on an as-sold basis, can range from approximately 2% to over 35% of the coal’s weight.  PRB coals have typical moisture content of 20% to 30%.

Mercury and chlorine are trace elements within coal that are of primary consideration relative to utility plant emissions and performance.  Trace amounts of mercury and chlorine in PRB coal are relatively low compared to coal from other regions.

Coal Mining Methods

Surface Mining

All of our mines are surface mining operations utilizing both dragline and truck-and-shovel mining methods.  Surface mining is used when coal is found relatively close to the surface.  Surface mining typically involves the removal of topsoil and drilling and blasting the overburden with explosives.  The overburden is then removed with draglines, trucks, shovels, and dozers.  Trucks and shovels then remove the coal.  The final step involves replacing the overburden and topsoil after the coal has been excavated, reestablishing vegetation into the natural habitat and making other changes designed to provide local community benefits.  We typically recover 90% or more of the economic coal seam for the mines we operate.

Table of Contents

Coal Preparation and Blending

In almost all cases, the coal from our mines is crushed and shipped directly from our mines to the customer.  Typically, no other preparation is needed for a saleable product.  However, coals of various sulfur and ash contents can be mixed or “blended” to meet the specific combustion and environmental needs of customers.  All of our coal can be blended with coal from other coal producers.  Spring Creek Mine’s location and the high Btu content of its coal make its coal better suited than our other coal for export and transportation to U.S. coal customers on the Great Lakes for blending by the customer with coal sourced from other locations to achieve a suitable overall product.

We currently operate solely in the PRB.  Two of the mines we operate are located in Wyoming, and one is located in Montana.  We currently own the majority of the equipment utilized in our mining operations.  We employ preventative maintenance and rebuild programs and upgrade our equipment as part of our efforts to ensure that it is productive, well maintained, and cost competitive.  Our maintenance programs also utilize procedures designed to enhance the efficiencies of our operations.  The following table provides summary information regarding our mines as of December 31, 2017.

(1)                     The tonnage shown for “Other” represents our purchases from third-party sources that we have resold.  See “—Mining Operations—Broker Sales and Third-Party Sources.”

Our Owned and Operated Mines segment includes our Antelope Mine, Cordero Rojo Mine, and Spring Creek Mine.  Our Antelope and Cordero Rojo mines are served by the BNSF and UP railroads.  Our Spring Creek Mine is served solely by the BNSF railroad.

The following map shows the locations of our mining operations:

Table of Contents

Antelope Mine

The Antelope Mine is located in the southern end of the PRB approximately 60 miles south of Gillette, Wyoming.  The mine extracts thermal coal from the Anderson and Canyon Seams, with up to 44 and 36 feet, respectively, in thickness.  Significant areas of unleased coal north and west of the mine are available for nomination by us or other mining operations or persons.  See Item 2 “Properties—Reserve Acquisition Process”.  Based on the average sulfur content of 0.50 lbs SO2/mmBtu, the reserves at our Antelope Mine are considered compliance coal under the Clean Air Act, and this coal is some of the lowest sulfur coal produced in the PRB.

Cordero Rojo Mine

The Cordero Rojo Mine is located approximately 25 miles south of Gillette, Wyoming.  The mine extracts thermal coal from the Wyodak Seam, which ranges from approximately 55 to 70 feet in thickness.  Significant additional areas of unleased coal are potentially available for nomination by us or other mining operations or persons adjacent to our current operations.  See Item 2 “Properties—Reserve Acquisition Process”.  Based on the average sulfur content of 0.66 lbs SO2/mmBtu, the reserves at our Cordero Rojo Mine are considered compliance coal under the Clean Air Act.

Spring Creek Mine

The Spring Creek Mine is located in Montana approximately 20 miles north of Sheridan, Wyoming.  The mine extracts thermal coal from the Anderson-Dietz Seam, which averages approximately 80 feet in thickness.  The location of the mine relative to the Great Lakes is attractive to our customers in the northeast because of lower transportation costs.  The location of the Spring Creek Mine also provides access to export terminals in the Pacific Northwest, providing a geographic advantage relative to other PRB mines.  During the years ended December 31, 2017, 2016, and 2015, we shipped approximately 4.2, 0.6, and 3.6 million tons, respectively, of Spring Creek coal through the Westshore terminal located in British Columbia, Canada.  Based on the average sulfur content of 0.73 lbs SO2/mmBtu, the reserves at our Spring Creek Mine are considered compliance coal under the Clean Air Act.

Development Projects

Youngs Creek Project

The Youngs Creek project, an undeveloped surface mine project in the Northern PRB region, is located in Wyoming, approximately 13 miles north of Sheridan, Wyoming, seven miles south of our Spring Creek Mine and seven miles from the mainline railroad, contiguous with the Wyoming-Montana state line.  It is near the Big Metal project (described below). We acquired the Youngs Creek project in June 2012.  The coal located at the Youngs Creek project is similar quality to that of our Spring Creek Mine and offers lower sodium levels.  We have not been able to classify the Youngs Creek project mineral rights as proven and probable reserves as they remain subject to further exploration and evaluation based on market conditions.  The Youngs Creek project mining permit covers 283.6 million tons of non-reserve coal deposits, of which approximately 267 million tons benefit from a royalty rate of 8.0% of the coal sales price free on board (“FOB”) at the mine site, payable to the sellers, which is below the normal 12.5% royalty rate payable on federal coal.  We control additional leased and private coal related to the Youngs Creek project that has not yet been evaluated and is not yet in any mine plan.  We also acquired approximately 38,800 acres of surface rights, which includes land extending north to our Spring Creek Mine, and onto the Crow Indian Reservation to the west.  We are in the process of evaluating the development options for this project and believe that its proximity to the Spring Creek Mine and the Big Metal project represent an opportunity to optimize our mine developments in the Northern PRB.

Big Metal Project

In January 2013, we entered into an option agreement and a corresponding exploration agreement with the Crow Tribe of Indians.  These agreements were approved by the Department of the Interior on June 14, 2013.  This coal project is located on the Crow Indian Reservation in southeast Montana, near our Spring Creek Mine and Youngs Creek project in the Northern PRB region.  Over the last five years, we have made option payments totaling $10 million to maintain the option agreement.  The option and exploration agreements provide for exploration rights and exclusive options to lease three separate coal deposits on the Crow Indian Reservation over an initial five-year term, which expires June 14, 2018, with two extension periods through 2035 if certain conditions are met.  Upon the exercise of an option or options to lease, we would pay the Crow Tribe an amount equal to $0.08 per ton to $0.15 per ton, depending on the lease area and coal deposit and subject to adjustment for inflation.  The agreements also set forth adjustable royalty rates, ranging from 7.5% to 15% of the coal sales price FOB at the mine site and contain standard coal production taxes to be paid to the Crow Tribe.  The coal

located at the Big Metal project is similar quality to that of our Spring Creek Mine and offers lower sodium levels.  We have completed the exploration program for the Big Metal project and are evaluating the development options for this project.  If we exercise our option and pursue development of the Big Metal project, we believe that its proximity to the Spring Creek Mine and the Youngs Creek project represents an opportunity to optimize our mine developments in the Northern PRB.

The map below shows where the Youngs Creek project and Big Metal project (Squirrel Creek, Tanner Creek, and Upper Youngs Creek coal deposits) are located relative to our Spring Creek Mine.

(1)                                 Non-reserve coal deposits are not reserves under SEC Industry Guide 7.  Estimates of non-reserve coal deposits are subject to further exploration and development, are more speculative, and may or may not be converted to future reserves of the company.

Customers, Contracts and Logistics Services

We focus on building long-term relationships with customers through our reliable performance and commitment to customer service.  We supply coal to 48 domestic and foreign electric utilities and over 72% of our sales were to customers with an investment grade credit rating as of December 31, 2017.  Furthermore, 83% of our 2017 sales were to customers with whom we have had relationships for more than 10 years.  During 2017, approximately 50% of our consolidated revenue was derived from our top ten customers.  No customer accounted for 10% or more of our total revenue in 2017, 2016, or 2015.

Coal produced approximately 30% of electricity generation in the U.S. through November 2017.  The following map shows the percentage of our tons sold by state of destination during 2017 from coal produced at the three mines we own and operate.  Our coal supplies fueled approximately 2% of the electricity generated in the U.S. in 2017.  Approximately 7% of the tons produced at our mines were sold to customers outside of the U.S. in 2017.

We categorize our customers by how we sell coal to them.  Our mine customers purchase coal directly from our mine sites, where the sale occurs at the mine site and where title and risk of loss typically pass to the customer at that point.

Table of Contents

Mine customers arrange for and bear the costs of transporting their coal from our mines to their plants or other specified discharge points.  Our mine customers are typically domestic utility companies primarily located in the mid-west and south central U.S., although we also sell to other domestic utility companies, as well as to third-party brokers.

Our logistics customers purchase coal from us, along with our logistics services to deliver the coal to the customer at a terminal or the customer’s plant or other delivery point remote from our mine site.  Title and risk of loss pass to the customer at the remote delivery point.  Our logistics services include the purchase of coal from third parties or from our owned and operated mines, at market prices, as well as the contracting and coordination of the transportation and other handling services from third-party operators, which are typically rail and terminal companies.  Logistics customers are primarily foreign and domestic utility companies as well as third-party brokers.  With respect to our international sales, at present, we are primarily focused on end-user customers.  However, a small portion of our sales are made to international traders who sell on to end-user customers.

Mine Customers

Coal Sales Agreements

As is customary in the coal industry, we generally enter into fixed price, fixed volume supply contracts with our mine customers.  Contracts with our mine customers historically featured terms of one to five years, although recent trends have been toward sales with shorter terms, including monthly and quarterly contracts.  This has led to greater variability and less long-term predictability of our sales.  For the year ended December 31, 2017, approximately 87% of our total revenue attributable to our Owned and Operated Mines segment was derived from supply contracts with terms of one year or greater.

Our coal is primarily sold on a mine-specific basis to utility customers through a request-for-proposal process.  The terms of our coal sales agreements result from competitive bidding and extensive negotiations with customers.  Consequently, the terms of these contracts vary by customer, including base price adjustment features, price re-opener terms, coal quality requirements, quantity parameters, permitted sources of supply, impact of future regulatory changes, extension options, force majeure, termination, assignment and other provisions.

Our coal sales agreements typically contain “hardship” provisions to adjust the base price due to new statutes, ordinances or regulations that affect our costs related to performance of the agreement.  Additionally, some of our contracts contain provisions that allow for the recovery of costs incurred as a result of modifications or changes in the interpretations or application of any applicable statute by local, state or federal government authorities.  These provisions only apply to the base price of coal contained in these supply contracts.  In some circumstances, a significant adjustment in base price can lead to termination of the contract.  In addition, a small number of our contracts contain clauses that may allow customers to terminate the contract in the event of significant changes in environmental laws and regulations, which result in the customer being unable to perform under the terms of the contract.

Most of our coal sales agreements to mine customers include a fixed price for the term of the agreement or a pre-determined escalation in price for each year.  Some of our customer contracts may include variable pricing.  These price re-opener and index provisions may allow either party to commence a renegotiation of the contract price at a pre-determined time.  Price re-opener provisions may automatically set a new price based on prevailing market price or, in some instances, require us to negotiate a new price, sometimes within specified ranges of prices.  In some agreements, if the parties do not agree on a new price, either party has an option to terminate the contract.  Under some of our contracts, we have the right to match lower prices offered to our customers by other suppliers.

Quality and volumes for the coal are stipulated in coal sales agreements.  Some customers are allowed to vary the amount of coal taken under the contract.  Most of our coal sales agreements contain provisions requiring us to deliver coal within certain ranges for specific coal characteristics, such as heat content, sulfur, ash and ash fusion temperature.  Failure to meet these specifications can result in economic penalties, suspension or cancellation of shipments or termination of the contracts.  Our contracts also typically attempt to account for the low sulfur content of our coal by reflecting a market adjustment for the low sulfur in the contract price or through an adjustment calculated based on the as-delivered average sulfur content of our coal, or both.

Contracts with our mine customers also typically contain force majeure provisions allowing temporary suspension of performance by us or our customers for the duration of specified events beyond the control of the affected party, including events such as strikes, adverse mining conditions, mine closures or serious transportation problems that affect us or unanticipated plant outages that may affect the buyer.  These contracts generally provide that, in the event a force majeure circumstance exceeds a certain period (e.g., 60-90 days), the unaffected party may have the option to terminate the

Table of Contents

transaction or transactions under the agreement.  Some of those contracts stipulate that this tonnage can be made up by mutual agreement or at the discretion of the buyer.  Generally, contracts with our mine customers allow our customers to suspend performance in the event that the railroad fails to provide its services due to circumstances that would constitute a force majeure under the terms of the contract between the mine customer and the railroad.

Many of our contracts contain clauses that require us and our customers to maintain a certain level of creditworthiness or provide appropriate credit enhancement upon request.  The failure to do so can result in a suspension of shipments under the contract.  In some of our contracts, we have a right of substitution, allowing us to provide coal from different mines, including third-party mines, as long as the replacement coal meets quality specifications and will be sold at the same delivered cost.

Generally, under the terms of our coal sales agreements, we agree to indemnify or reimburse our customers for damage to their or their rail carrier’s equipment resulting from our negligence, and for damage to their equipment due to non-coal materials being included with our coal before leaving our property.

Transportation

Transportation is typically one of the largest components of a purchaser’s total cost.  Coal used for domestic consumption by our mine customers is typically sold FOB at the mine or nearest loading facility, and the purchaser of the coal bears the transportation costs and risk of loss.  Most electric generators arrange long-term shipping contracts with rail or barge companies to assure stable delivery costs.  Our Antelope and Cordero Rojo mines are served by the BNSF and UP railroads.  Our Spring Creek Mine is served solely by the BNSF railroad.

Although the purchaser pays the freight, transportation costs still are important to coal mining companies because the purchaser will consider the delivered cost of coal, including transportation costs, in determining from which mines it will purchase.  Transportation costs borne by the customer vary greatly based on each customer’s proximity to the mine.

Logistics Customers

Coal Sales Agreements

We generally enter into binding contracts that are fixed-price, fixed-volume supply contracts with our domestic logistics customers.  Contracts with these logistics customers generally have terms of one to three years.  The terms of our sales agreements result from competitive bidding and extensive negotiations with customers.  Consequently, the terms of these contracts vary by customer, including base price adjustment features, price re-opener terms, logistics and coal quality requirements, quantity parameters, permitted sources of supply, impact of future regulatory changes, extension options, force majeure, termination, assignment and other provisions.

With our international logistics customers, we often enter into contracts that contain multi-year terms with future year pricing to be agreed upon, meaning that there is an expectation of sales, provided that mutual agreement on pricing can be reached.  This is consistent with conventional industry standards for sales into the Asian Pacific region.  Our Asian delivered shipments are typically priced broadly in line with a number of relevant international coal indices adjusted for energy content and other quality and delivery criteria.  These indices include the Newcastle benchmark price, as published by Global Coal and others, and the Platts Kalimantan 5000.  The Newcastle benchmark price is an established index for high Btu Australian bituminous thermal coal available to be loaded on a vessel at a coal terminal near Newcastle, north of Sydney.  The Kalimantan 5000 is an established index for subbituminous Indonesian thermal coal.  Our delivered sales are generally priced at a range between 60% to 75% of the forward Newcastle price and at a smaller discount to the forward Kalimantan 5000 price due to quality and freight cost differentials.

Contracts with our logistics customers include terms similar to those described for our mine customers and may include terms relating to:

·                  demurrage fees for international contracts, charged to us when a vessel is not dispatched in the agreed-upon time;

·                  fixed pricing for the current year of sales, and a provision providing for future years’ pricing to be negotiated by a specific point in time for some of our foreign contracts; and

·                  additional coal quality requirements, such as grindability, which deals with the hardness of the coal, and ash fusion temperature, which measures the softening and melting behavior of the ash contained in the coal.

Transportation and Logistics Services

For our logistics customers, we provide a variety of services designed to facilitate the sale and delivery of coal.  These services include the purchase of coal from third parties or from our owned and operated mines, coordination of the transportation and delivery of purchased coal, negotiation of take-or-pay rail agreements and take-or-pay port agreements and demurrage settlements with vessel operators.  We also bear the costs of transporting the coal to the delivery point.  For our international customers, this generally means that we cover the costs associated with an export terminal located in the Pacific Northwest.  Our logistics customers located overseas are generally responsible for paying the cost of ocean freight, although occasionally we may arrange or be responsible for the cost of that transportation as well.

We have an agreement with an unaffiliated Korean representative company, WoonBong Energy, which helps us facilitate our sales in South Korea.  WoonBong Energy provides market research on Korean coal customers and demand, acts as an intermediary for communications with our Korean customers and assists with logistics issues in sales to Korean customers.  WoonBong Energy provides these services exclusively for us in South Korea.  We have similar arrangements in certain other Asian countries.

To help support and ensure export terminal capacity for export sales, we enter into multi-year throughput agreements with export terminal companies and railroads.  These types of take-or-pay agreements require us to pay for a minimum quantity of coal to be transported on the railway or through the terminal regardless of whether we sell any coal.  If we fail to make sufficient export sales to meet our minimum obligations under the take-or-pay agreements, we are still obligated to make payments to the export terminal company or railroad.  See Item 7—“Management’s Discussion and Analysis of Financial Condition and Results of Operations — Contractual Obligations” for more detail.  Also included in the costs within our Logistics and Related Activities segment are fees to cover rail and export terminal charges, as well as fees to cover capital costs and investments that we incur to enable us to provide logistics services to our logistics customers, such as the purchase or lease of rail cars.

Historical Logistics Agreements

In 2011, we entered into a multi-year throughput contract with Westshore Terminals Limited Partnership (“Westshore”) for a portion of our anticipated export sales through their export terminal in Vancouver, British Columbia.  In August 2014, we increased our long-term committed capacity at Westshore from 2.8 million tons to 6.3 million tons initially, increasing to 7.2 million tons in 2019.  In addition, the revised agreement extended the term of our throughput agreement by two years through the end of 2024.

In October 2015, we announced an amended agreement with Westshore whereby the previously committed volumes for 2016 through 2018 were reduced to zero in exchange for an upfront payment made in October 2015, plus quarterly payments during 2016 through 2018, as specified in the amended agreement.  In December 2015, we announced a similar amendment to our transportation agreement with BNSF.

In November 2016, due to the improvement in export coal prices, we entered into agreements with Westshore and BNSF to ship coal during the fourth quarter of 2016.  These agreements were effective for the fourth quarter of 2016 only, and did not change the aforementioned amended agreements discussed above, or the terms of the previous throughput or transportation agreements.  Under the fourth quarter agreements, we received a partial credit against current charges for the quarterly payments made under the previous agreements.

At December 31, 2016, we terminated our previous agreement with Westshore and entered into a new agreement.  In February 2017, we terminated our previous agreement with BNSF and entered into a new agreement effective in April 2017.  The new agreements provided for shipments in 2017 and 2018 and required minimum payments for those two years.  We had the right to terminate our commitments at any time in exchange for buyout payments.

We also previously had a minority ownership interest in the joint venture that was seeking to develop Gateway Pacific Terminal (“GPT”) in Washington State.  SSA Marine, the majority interest holder and project developer, notified us of its intention to no longer pursue a coal terminal.  As a result, in January 2017, we abandoned our ownership interest in the joint venture, and we no longer have any ownership interest or associated funding obligations for the joint venture.  We continue to have residual contractual rights as a potential customer of the terminal if the project is resumed in a designated period of time in the future.  The abandonment of our interest in GPT had no effect on our financial statements since we fully impaired our investment in 2015.

Current Logistics Agreements

On December 28, 2017, we extended our agreement with Westshore through the end of 2020.  We signed a corresponding agreement with BNSF on January 9, 2018, also extending through the end of 2020.  Additionally, after the new Westshore agreement terminates and through 2024, if we choose to ship to export customers, we are required to offer to ship through Westshore up to a specified annual tonnage on terms similar to the new agreement before shipping through any other export terminal.  Westshore has the right to accept or reject our offer in its sole discretion.  See Note 9 of Notes to Consolidated Financial Statements in Item 8 for further discussion regarding the accounting treatment of these transactions.

In addition to our current port agreement with Westshore, we hold an option contract to increase our future export capacity through the proposed Millennium Bulk Terminals (“MBT”) coal export facility in Washington State.  The timing and outcome of the permit process related to MBT, and therefore the construction of the terminal, is uncertain.

Broker Sales and Third-Party Sources

From time to time, we purchase coal through brokers.  We also sell any excess produced coal to brokers and third-party sources, including brokers who sell to end users in foreign countries.  For delivery during each of the years ended December 31, 2017, 2016, and 2015, we purchased and resold 0.3 million tons, through brokers and third-party sources.

Sales and Marketing

We have a team of experienced sales, marketing, and customer service personnel.  To help develop and maintain the relationships we have with our mine and logistics customers, we have divided the department into teams consisting of:

·                  Sales and Marketing, which focuses on traditional requests for proposals by our mine customers and after sales service;

·                  Logistics, which provides logistical and additional contract support to our domestic customers, and also focuses on logistics, transportation and related services on behalf of our Logistics and Related Activities segment;

·                  Trading and Revenue Management, which provides industry insight, recommends pricing strategies and participates in the spot and forward markets; and

·                  Export Sales, which focuses on sales to our international logistics customers.

As of February 7, 2018, we had 11 employees in our sales and marketing department.

Suppliers

Principal supplies used in our business include heavy mobile equipment, petroleum-based fuels, explosives, tires, steel and other raw materials, as well as spare parts and other consumables used in the mining process.  We use third-party suppliers for a portion of our equipment rebuilds and repairs, drilling services and construction.  We use sole source suppliers for certain parts of our business such as dragline shovel parts and services and tires.  We believe adequate substitute suppliers are available.  For further discussion of our suppliers, see Item 1A “Risk Factors—Risks Related to Our Business and Industry—Increases in the cost of raw materials and other industrial supplies, or the inability to obtain a sufficient quantity of those supplies, could increase our operating expenses, disrupt or delay our production and materially adversely affect our profitability.”

Competition

The coal industry is highly competitive.  See Item 1A “Risk Factors—Risks Related to Our Business and Industry—Competition with domestic and foreign coal producers, with traders and re-sellers of coal and with producers of natural gas and other competing energy sources may continue to negatively affect our sales volumes and our ability to sell coal at a favorable price.”  We compete with other coal producers, with traders and re-sellers of coal and with other energy producers throughout the U.S. and, for our export sales, internationally.  The most important factors on which we compete with other coal producers and with traders and re-sellers of coal are coal price, coal quality and characteristics, costs to transport the coal, customer service, and the reliability of supply.  Demand for coal and the prices that we will be able to obtain for our coal are closely linked to coal consumption patterns of the domestic and foreign electric generation industries.  These coal consumption patterns are influenced by factors beyond our control, including weather and economic conditions,  the supply and demand for domestic and foreign electricity, domestic and foreign governmental regulations and taxes, environmental

and other regulatory changes, global climate change initiatives, technological developments, the price and availability of other fuels, such as natural gas and crude oil, the availability of subsidies, and renewable mandates designed to encourage greater use of alternative energy sources, including hydroelectric, nuclear, wind and solar power, and currency exchange rate fluctuations, all of which can decrease demand for thermal coal or may decrease demand for PRB coal compared to other global coal basins.

Because the U.S. federal government owns most of the coal in the vicinity of our mines, we compete with other coal producers operating in the PRB for additional coal through the competitive LBA process.

Employees

As of February 7, 2018, we had approximately 1,300 full-time employees.  None of our employees are currently parties to collective bargaining agreements.  We believe that we have good relations with our employees.  As of February 7, 2018, we had approximately 140 external contractors on a full-time, equivalent basis.

Environmental and Other Regulatory Matters

Federal, state and local authorities regulate the U.S. coal mining industry with respect to various matters, including air quality standards, water pollution, plant and wildlife protection, the discharge of materials into the environment and the effects of mining on surface and groundwater quality and availability.  These laws and regulations, which are extensive, change frequently, and have tended to become stricter over time, have had, and will continue to have, a significant adverse effect on our production costs and our competitive position relative to certain other sources of electricity generation.  Future laws, regulations, orders, or treaties, including those relating to global climate change, may continue to cause coal to become a less attractive fuel source, thereby further reducing coal’s share of the market for fuels and other energy sources used to generate electricity.  See “Environmental and Other Regulatory Matters—Global Climate Change.”

We are committed to conducting our mining operations in compliance with all applicable federal, state and local laws and regulations.  We have procedures in place that are designed to enable us to comply with these laws and regulations.  As an example, all of the mines we operate are certified to the international standard for environmental management systems (“ISO 14001”).  We believe we are substantially in compliance with applicable laws and regulations.  However, due to the complexity and interpretation of these laws and regulations, we cannot guarantee that we have been or will be at all times in complete compliance.

Mining Permits and Approvals

Numerous governmental permits or approvals are required for mining operations.  When we apply for these permits and approvals, we may be required to prepare and present data to federal, state or local authorities pertaining to the effect or impact that any proposed production or processing of coal may have upon the environment.  For example, in order to obtain a federal coal lease, an EIS must be prepared to assist the BLM in determining the potential environmental impact of lease issuance, including any direct and indirect effects from the mining, transportation and burning of coal.  In recent years, particular attention has been focused on the impact of the production and usage of coal on global climate change.  This has resulted in extensive comments and regulatory litigation from environmental groups.  See also Note 17 of Notes to Consolidated Financial Statements in Item 8 for a discussion regarding certain challenges by environmental activist groups against various regulatory processes impacting our mines.  Accordingly, our nominations or lease applications may be subject to delays or challenges.  In order to obtain mining permits and approvals from federal and state regulatory authorities, mine operators must also submit a reclamation plan for restoring, upon the completion of mining operations, the mined property to its prior condition, productive use or other permitted condition.  Typically, we submit the necessary permit applications several months or even years before we plan to begin mining a new area.  In the states where we operate, the applicable laws and regulations also provide that a mining permit or modification can be delayed, refused or revoked if officers, directors, stockholders with specified interests or certain other affiliated entities with specified interests in the applicant or permittee have, or are affiliated with another entity that has, outstanding permit violations.  Thus, past or ongoing violations of applicable laws and regulations by these interested persons and entities could provide a basis to revoke our existing permits and to deny the issuance of additional permits.  As a result of these requirements, the authorization, permitting and implementation requirements imposed by federal, state and local authorities may be costly and time consuming and may limit or delay commencement or continuation of mining operations.  Under some circumstances, substantial fines and penalties, including revocation or suspension of mining permits, may be imposed under governing laws, rules and regulations.  Monetary sanctions and, in severe circumstances, criminal sanctions may be imposed for failure to comply with these laws.

Permitting requirements also require, under certain circumstances, that we obtain surface owner consent if the surface estate has been split from the mineral estate.  This requires us to negotiate with third parties for surface access that overlies coal we acquired or intend to acquire.  These negotiations can be costly and time-consuming, lasting years in some instances, which can create additional delays in the permitting process.  If we cannot successfully negotiate for land access, we could be denied a permit to mine coal we already own.

Surface Mining Control and Reclamation Act

SMCRA establishes mining, environmental protection, reclamation and closure standards for all aspects of surface coal mining. Mining operators must obtain SMCRA permits and permit renewals from the federal Office of Surface Mining (“OSM”) or from the applicable state agency if the state agency has obtained regulatory primacy by developing a mining

12

Table of Contents

regulatory program no less stringent than that established under SMCRA.  Both Wyoming and Montana, where our owned and operated mines are located, have achieved primacy to administer the SMCRA program.

SMCRA permit provisions include a complex set of requirements, which include, among other things, coal prospecting, mine plan development, topsoil or growth medium removal and replacement, selective handling of overburden materials, mine pit backfilling and grading, disposal of excess spoil, protection of the hydrologic balance, surface runoff and drainage control, establishment of suitable post mining land uses and re-vegetation.  We begin the process of preparing a mining permit application by collecting baseline data to adequately characterize the pre-mining environmental conditions of the permit area.  This work is typically conducted by third-party consultants with specialized expertise and typically includes surveys and/or assessments of: cultural and historical resources; geology; soils; vegetation; aquatic organisms; wildlife; potential for threatened, endangered or other special status species; surface and ground water hydrology; climatology; riverine and riparian habitat and wetlands.  The geologic data and information derived from the surveys and/or assessments are used to develop the mining and reclamation plans presented in the permit application, which address the provisions and performance standards of the state’s equivalent SMCRA regulatory program.  SMCRA permit applications also include information used for documenting surface and mineral ownership, variance requests, access roads, mining methods, mining phases, other agreements that may relate to coal, other minerals, oil and gas rights, water rights, permitted areas and ownership and control information required to determine compliance with OSM’s regulations, including information regarding mining and compliance history.  A mine operator must also submit a bond or otherwise secure the performance of all reclamation obligations associated with the proposed activities.

Upon submission to the regulatory agency, a permit application goes through an administrative completeness review and a thorough technical review.  Public notice of the proposed permit is required, beginning a notice and comment period that is required before a permit can be issued.  It is not uncommon for a SMCRA mine permit application to take over two years to prepare and review, depending on the size and complexity of the mine, and another two or more years for the permit to be issued, depending primarily on the regulatory authority’s approach to handling comments and objections received from the general public and other agencies.  Also, it is not uncommon for a permit to be delayed as a result of litigation related to the specific permit or another related company’s permit.

From time to time, OSM will also update its mining regulations under SMCRA. For example, in December 2016, the OSM published a final rule to revise its regulations related to protecting streams and related wildlife from adverse impacts of surface coal mining operations.  The rule would have imposed stricter guidelines on conducting coal mining operations within buffer zones; required mine operators to collect additional baseline data about the site of the proposed mining operation and adjacent areas; imposed additional surface and groundwater monitoring requirements; enacted specific requirements for the protection or restoration of perennial and intermittent streams; and imposed additional bonding and financial assurance requirements.  In February 2017, the rule was revoked pursuant to the Congressional Review Act. Accordingly, the rule has no force or effect and cannot be replaced by a similar rule absent future legislation.  This type of rule or other new SMCRA regulations could result in additional material costs, obligations, and restrictions associated with our operations.

In addition to the bond requirement described above, the Abandoned Mine Land Fund, which was created by SMCRA, imposes a fee on all coal produced.  The proceeds of the fee are used to restore mines closed or abandoned prior to SMCRA’s adoption in 1977.  The current fee is $0.28 per ton of coal produced from surface mines.  In 2017, 2016, and 2015 we recorded $16.1 million, $16.3 million, and $20.9 million, respectively, of expense related to these reclamation fees.

Surety Bonds

Federal and state laws require a mine operator to secure the performance of its reclamation and lease obligations required under SMCRA through the use of surety bonds or other approved forms of security to cover the costs the state would incur if the mine operator were unable to fulfill its obligations.  As of December 31, 2017, there were approximately $422.9 million in third-party surety bonds outstanding to primarily secure the performance of our reclamation and lease obligations.  At some point, federal and state laws may be amended to require certain forms of financial assurance that are more costly to obtain.  Recently, there has been heightened regulatory pressure on reclamation bonding and self-bonding in particular.  We exited self-bonding in the first quarter of 2017.  As a result of credit pressures on the coal industry, it is possible that surety bond providers could demand cash collateral as a condition to providing or maintaining surety bonds.  Any such demands, depending on the amount of any cash collateral required, could have a material adverse impact on our liquidity and financial position.  If we are unable to meet cash collateral requirements and cannot otherwise obtain or retain required surety bonds, we may be unable to satisfy legal requirements necessary to conduct our mining operations.

Mine Safety and Health

Stringent health and safety standards have been in effect since Congress enacted the Coal Mine Health and Safety Act of 1969.  The Federal Mine Safety and Health Act of 1977 (the “Mine Act”), significantly expanded the enforcement of safety and health standards and imposed safety and health standards on all aspects of mining operations.  In addition to federal regulatory programs, all of the states in which we operate also have state programs for mine safety and health regulation and enforcement.  Collectively, federal and state safety and health regulation in the coal mining industry is among the most comprehensive and pervasive systems for protection of employee health and safety affecting any segment of U.S. industry.  The Mine Act is a strict liability statute that requires mandatory inspections of surface and underground coal mines and requires the issuance of enforcement action when it is believed that a standard has been violated.  A penalty is required to be imposed for each cited violation.  Negligence and gravity assessments result in a cumulative enforcement arrangement that may result in the issuance of withdrawal orders.  The Mine Act also contains criminal liability provisions.  For example, it imposes criminal liability for corporate operators who knowingly or willfully authorize, order or carry out violations and for any person who knowingly falsifies records required under the Mine Act.  The Mine Act also provides that civil and criminal penalties may be assessed against individual agents, officers and directors who knowingly authorize, order or carry out violations.

In 2006, in response to underground mine accidents, Congress enacted the Mine Improvement and New Emergency Response Act (the “MINER Act”). The MINER Act significantly amended the Mine Act, requiring improvements in mine safety practices, increasing criminal penalties and establishing a maximum civil penalty for non-compliance, and expanding the scope of federal oversight, inspection and enforcement activities.   Since passage of the MINER Act, and particularly since the April 2010 explosion at Massey Energy Company’s (previously acquired by Alpha Natural Resources) Upper Big Branch Mine, enforcement scrutiny has increased, including more inspection hours at mine sites, increased numbers of inspections and increased issuance of the number and the severity of enforcement actions and related penalties. Various states also have enacted their own new laws and regulations addressing many of these same subjects.  MSHA continues to interpret and implement various provisions of the MINER Act, along with introducing new proposed regulations and standards. For example, the second phase of the MSHA’s respirable coal mine dust rule went into effect in February 2016, and requires increased sampling frequency and the use of continuous personal dust monitors. In August 2016, the third and final phase of the rule became effective, reducing the overall respirable dust standard in coal mines from 2.0 to 1.5 milligrams per cubic meter of air.  Our compliance with these or any other new mine health and safety regulations could increase our mining costs.

We have implemented various internal standards to promote employee health and safety.  In addition, we are also Occupational Health and Safety Assessment Series 18001 certified.  Nevertheless, if we were to be found in violation of mine safety and health regulations, we could face penalties or restrictions that may materially and adversely impact our operations, financial results and liquidity.

Black Lung

Under the Black Lung Benefits Revenue Act of 1977 and the Black Lung Benefits Reform Act of 1977, as amended in 1981, each coal mine operator must pay federal black lung benefits to claimants who are current and former employees and also make payments to a trust fund for the payment of benefits and medical expenses to claimants who last worked in the coal industry prior to January 1, 1970.  The trust fund is funded by an excise tax on production of up to $1.10 per ton for deep-mined coal and up to $0.55 per ton for surface-mined coal, neither amount to exceed 4.4% of the gross sales price.  The excise tax does not apply to coal shipped outside the U.S.  In 2017, 2016, and 2015 we recorded $26.4 million, $28.6 million, and $36.3 million, respectively, of expense related to this excise tax.

The Patient Protection and Affordable Care Act includes significant changes to the federal black lung program including an automatic survivor benefit paid upon the death of a miner with an awarded black lung claim and establishes a rebuttable presumption with regard to pneumoconiosis among miners with 15 or more years of coal mine employment that are totally disabled by a respiratory condition. These changes could have a material impact on our costs expended in association with the federal black lung program.  For miners last employed as miners after 1969 and who are determined to have contracted black lung, we maintain coverage to help cover the cost of present and future claims through the use of trusts or insurance policies.  We may also be liable under state laws for black lung claims that are covered through insurance policies.

Clean Air Act

The CAA and comparable state laws that regulate air emissions affect coal mining operations both directly and indirectly.  Direct impacts on coal mining and processing operations include CAA permitting requirements and emission

14

Table of Contents

control requirements relating to air pollutants, including particulate matter, which may include controlling fugitive dust.  The CAA indirectly affects coal mining operations by extensively regulating the emissions of particulate matter, sulfur dioxide, nitrogen oxides, mercury and other compounds emitted by coal-fired power plants.  In recent years, Congress has considered legislation that would require increased reductions in emissions of sulfur dioxide, nitrogen oxide and mercury.  In addition to the GHG issues discussed below, the air emissions programs that may materially and adversely affect our operations, financial results, liquidity, and demand for our coal, directly or indirectly, include, but are not limited to, the following:

·                  Acid Rain.  Title IV of the CAA requires reductions of sulfur dioxide emissions by electric utilities.  Affected power plants have sought to reduce sulfur dioxide emissions by switching to lower sulfur fuels, installing pollution control devices, reducing electricity generating levels or purchasing or trading sulfur dioxide emission allowances.  We cannot accurately predict the future effect of these Clean Air Act provisions on our operations.

·                  NAAQS for Criterion Pollutants.  The CAA requires the EPA to set standards, referred to as NAAQS, for six common air pollutants, including nitrogen oxide, sulfur dioxide, particulate matter, and ozone.  Areas that are not in compliance (referred to as non-attainment areas) with these standards must take steps to reduce emissions levels.  Although our operations are not currently located in non-attainment areas, we could be required to incur significant costs to install additional emissions control equipment, or otherwise change our operations and future development if that were to change.  Over the past several years, the EPA has revised its NAAQS for nitrogen oxide, sulfur dioxide, and particulate matter, and, in November 2014, proposed a revised standard for ozone, in each case making the standards more stringent.  The EPA has determined that the areas in which we operate are classified under the new nitrogen oxide standard as “unclassifiable/attainment”. Based on the EPA’s third round of area designations, no areas in which we operate have been designated as nonattainment under the 2010 revised sulfur dioxide NAAQS. In November 2015, the EPA also revised the NAAQS for ground level ozone to a stricter, lower standard of 70 parts per billion.  The EPA issued preliminary nonattainment designations in December 2017 and has announced its intention to issue final attainment status designations during the first half of 2018.  Certain areas of the country previously in compliance with the various NAAQS standards may be reclassified as non-attainment.  Such reclassification may make it more difficult to construct new or modified sources of air pollution in newly designated non-attainment areas.

·                  Clean Air Interstate Rule and Cross-State Air Pollution Rule.  CAIR calls for power plants in 28 states and the District of Columbia to reduce emission levels of sulfur dioxide and nitrogen oxide pursuant to a cap-and-trade program similar to the system now in effect for acid rain.  In June 2011, the EPA finalized CSAPR, a replacement rule to CAIR, which requires 28 states in the Midwest and eastern seaboard of the U.S.to reduce power plant emissions that cross state lines and contribute to ozone and/or fine particle pollution in other states.  Nitrogen oxide and sulfur dioxide emissions reductions were scheduled to commence in 2012, with further reductions effective in 2014.  However, in August 2012, the U.S. Court of Appeals for the District of Columbia Circuit (the “D.C. Circuit”) vacated CSAPR and ordered the EPA to continue enforcing CAIR.  In April 2014, the U.S. Supreme Court reversed the D.C. Circuit’s decision vacating CSAPR.  The EPA subsequently moved the Appeals Court for an order lifting the stay of CSAPR and extending the CSAPR compliance deadlines.  In October 2014, the Court granted the EPA’s request to lift the stay, and in November 2014, the EPA issued an interim final rule reconciling the CSAPR rule with the Court’s order, which calls for Phase 1 implementation in 2015 and Phase 2 implementation in 2017.  In September 2016, the EPA finalized an update to the CSAPR ozone season program by issuing the Final CSAPR Update.  For states to meet their requirements under CSAPR, a number of coal-fired electric generating units will likely need to be retired, rather than retrofitted with the necessary emission control technologies, reducing demand for thermal coal.

·                  NOx State Implementation Plan Call.  The NOx SIP Call program was established by the EPA in October 1998 to reduce the transport of nitrogen oxide and ozone on prevailing winds from the Midwest and South to states in the Northeast, which alleged that they could not meet federal air quality standards because of migrating pollution.  The program is designed to reduce nitrogen oxide emissions by one million tons per year in 22 eastern states and the District of Columbia.  As a result of the program, many power plants have been or will be required to install additional emission control measures, such as selective catalytic reduction devices.  Installation of additional emission control measures will make it more costly to operate coal-fired power plants, potentially making coal a less attractive fuel.

·                  Mercury and Hazardous Air Pollutants.  In February 2012, the EPA formally adopted a rule to regulate emissions of mercury and other metals, fine particulates, and acid gases such as hydrogen chloride from coal- and oil-fired power plants, referred to as “MATS”.  In March 2013, the EPA finalized reconsideration of the MATS rule as it pertains to

15

Table of Contents

new power plants, principally adjusting emissions limits for new coal-fired units to levels considered attainable by existing control technologies.  In subsequent litigation, the U.S. Court of Appeals for the D.C. Circuit upheld various portions of the rulemaking in two separate decisions issued in March and April 2014, respectively.  In June 2015, the U.S. Supreme Court struck down the MATS rule based on the EPA’s failure to take costs into consideration and remanded the case back to the D.C. Circuit.  The D.C. Circuit has remanded the rule to the EPA, but allowed the current rule to stay in place until the EPA issues a new finding.  In April 2016, the EPA issued a final finding that it is appropriate and necessary to set standards for emissions of air toxics from coal- and oil-fired power plants.  Apart from MATS, several states have enacted or proposed regulations requiring reductions in mercury emissions from coal-fired power plants, and federal legislation to reduce mercury emissions from power plants has been proposed.  Regulation of mercury emissions by the EPA, states, Congress, or pursuant to an international treaty may further decrease the demand for coal.  Like CSAPR, MATS and other similar future regulations could accelerate the retirement of a significant number of coal-fired power plants, in addition to the significant number of plants and units that have already been retired as a result of environmental and regulatory requirements and uncertainties adversely impacting coal-fired generation.  Such retirements would adversely impact our business.

·                  Regional Haze, New Source Review and Methane.  The EPA has initiated a regional haze program to protect and improve visibility at and around national parks, national wilderness areas and international parks.  In December 2011, the EPA issued a final rule under which the emission caps imposed under CSAPR for a given state would supplant the obligations of that state with regard to visibility protection.  In May 2012, the EPA finalized a rule that allows the trading programs in CSAPR to serve as an alternative to determining source-by-source Best Available Retrofit Technology (“BART”). This rule provides that states in the CSAPR region can substitute participation in CSAPR for source-specific BART for sulfur dioxide and/or nitrogen oxides emissions from power plants.  The Tenth Circuit Court of Appeals is hearing Wyoming’s challenge to the EPA’s partial disapproval of the State’s related plan for reducing emissions of haze-causing nitrogen dioxide.  Wyoming’s current plan to mitigate nitrogen dioxide will continue during the appeal.  Following a settlement agreement between certain parties to the case, the Court abated all proceedings in the case pending final action on the settlement agreement.

·                  In addition, the EPA’s new source review program under certain circumstances requires existing coal-fired power plants, when modifications to those plants significantly change emissions, to install the more stringent air emissions control equipment required of new plants.  Litigation seeking to force the EPA to list coal mines as a category of air pollution sources that endanger public health or welfare under Section 111 of the CAA and establish standards to reduce emissions from sources of methane and other emissions related to coal mines was dismissed by the D.C. Circuit in May 2014.  In that case, the Court denied a rulemaking petition citing agency discretion and budgetary restrictions, and ruled the EPA has reasonable discretion to carry out its delegated responsibilities, which includes determining the timing and relative priority of its regulatory agenda.  In July 2014, the D.C. Circuit denied a petition seeking a rehearing of the case en banc.  Litigation around these issues may continue, and could result in the need for additional air pollution controls for coal-fired units and our operations.

Global Climate Change

Global climate change initiatives and public perceptions regarding fossil fuels have resulted, and are expected to continue to result, in decreased coal-fired power plant capacity and utilization, phasing out and closing many existing coal-fired power plants, reducing or eliminating construction of new coal-fired power plants in the United States and certain other countries, increased costs to mine coal and decreased demand and prices for thermal coal, including PRB coal.

There are three important sources of GHGs associated with the coal industry.  The end use of our coal in electricity generation is the largest of the three sources of GHGs.  Combustion of fuel for mining equipment used in coal production is another source of GHGs.  In addition, coal mining can release methane, a GHG, directly into the atmosphere.  These emissions from coal consumption and production are subject to pending and proposed regulation as part of initiatives to address global climate change.

The Kyoto Protocol to the 1992 United Nations Framework Convention on Climate Change (the “Kyoto Protocol”) became effective in 2005, and bound those developed countries that ratified it (which the U.S. did not do) to reduce their global GHG emissions.  Discussions to develop a treaty to replace the Kyoto Protocol after its expiration in 2012 are still ongoing.  Most recently, the United Nations Framework Convention on Climate Change met in Paris, France in December 2015 and agreed to an international climate agreement.  Although this agreement does not create any binding obligations for nations to limit their GHG emissions, it does include pledges to voluntarily limit or reduce future emissions.  The Paris climate agreement entered into force in November 2016.  However, in August 2017, the U.S. State Department officially informed the United Nations of the intent of the U.S. to withdraw from the agreement, with the earliest possible effective date

16

Table of Contents

of withdrawal being November 4, 2020.  Despite the planned withdrawal, certain U.S. city and state governments have announced their intention to satisfy their proportionate obligations under the Paris Agreement.  These commitments could further reduce demand and prices for our coal.

The EPA has adopted rules requiring the reporting of GHG emissions from specified large GHG emission sources in the U.S., including coal-fired electric power plants, and begun adopting and implementing regulations to restrict emissions of GHGs under existing provisions of the CAA.  These rules were legally challenged, but in June 2012, the D.C. Circuit denied these challenges.  Among the rules promulgated after the EPA’s endangerment finding was the Tailoring Rule, which requires that all new or modified stationary sources of GHGs that will emit more than 75,000 tons of carbon dioxide per year and are otherwise subject to CAA regulation, and any other facilities that will emit more than 100,000 tons of carbon dioxide per year, to undergo prevention of significant deterioration (“PSD”) permitting, which requires that the permitted entity adopt the best available control technology.   As a result, the EPA is now requiring new sources, including coal-fired power plants, to undergo control technology reviews for GHGs (predominately carbon dioxide) as a condition of permit issuance.  These reviews may impose limits on GHG emissions, or otherwise be used to compel consideration of alternative fuels and generation systems, as well as increase litigation risk for—and so discourage development of—coal-fired power plants.

Additionally, the U.S. Supreme Court, in a decision issued in June 2014, addressed whether the EPA’s regulation of GHG emissions from new motor vehicles properly triggered GHG permitting requirements for stationary sources under the CAA.  The decision reversed, in part, and affirmed, in part, a 2012 D.C. Circuit decision that upheld the EPA’s GHG-related regulations.  Specifically, the Court held that the EPA exceeded its statutory authority when it interpreted the CAA to require PSD and Title V permitting for stationary sources based on their potential GHG emissions. However, the Court also held that the EPA’s determination that a source already subject to the PSD program due to its emission of conventional pollutants may be required to limit its GHG emissions by employing the “best available control technology” was permissible.

In August 2015, the EPA issued its final Clean Power Plan (“CPP”) rules that establish carbon pollution standards for power plants, called CO2 emission performance rates.  Judicial challenges led the U.S. Supreme Court to grant a stay in February 2016 of the implementation of the CPP before the United States Court of Appeals for the District of Columbia (“Circuit Court”) even issued a decision.  By its terms, this stay will remain in effect throughout the pendency of the appeals process including at the Circuit Court and the Supreme Court through any certiorari petition that may be granted.   The Supreme Court’s stay applies only to EPA’s regulations for CO2 emissions from existing power plants and will not affect EPA’s standards for new power plants.  It is not yet clear how either the Circuit Court or the Supreme Court will rule on the legality of the CPP. Additionally, in October 2017 EPA proposed to repeal the CPP, although the final outcome of this action and the pending litigation regarding the CPP is uncertain at this time.   In connection with this proposed repeal, EPA issued an Advance Notice of Proposed Rulemaking (“ANPRM”) in December 2017 regarding emission guidelines to limit GHG emissions from existing electricity utility generating units.  The ANPRM seeks comment regarding what the EPA should  include in a potential new, existing-source regulation under the Clean Air Act of GHG emissions from electric utility generating units that it may propose.  If the effort to repeal the rules is unsuccessful and the rules were upheld at the conclusion of this appellate process and were implemented in their current form, or if the ANPRM results in a different proposal to control GHG emissions from electric utility generating units, demand for coal would likely be further decreased, potentially significantly, and our business would be adversely impacted.

Various states and regions have adopted GHG initiatives and certain governmental bodies, including the State of California, have or are considering the imposition of fees or taxes based on the emission of GHGs by certain facilities.  A number of states have enacted legislative mandates requiring electricity suppliers to use renewable energy sources to generate a certain percentage of power.

These and other current or future global climate change laws, regulations, court orders or other legally enforceable mechanisms, or related public perceptions regarding climate change, are expected to require additional controls on coal-fired power plants and industrial boilers and may cause some users of coal to further switch from coal to alternative sources of fuel, thereby depressing demand and pricing for coal.

Clean Water Act

The Clean Water Act (“CWA”) and corresponding state and local laws and regulations affect coal mining operations by restricting the discharge of pollutants, including dredged or fill materials, into waters of the U.S.  The CWA provisions and associated state and federal regulations are complex and subject to amendments, legal challenges and changes in implementation.  Congress has also considered legislation that seeks to clarify the scope of CWA jurisdiction.  Recent court decisions, regulatory actions and proposed legislation have created uncertainty over CWA jurisdiction and permitting requirements.

17

Table of Contents

CWA requirements that may directly or indirectly affect our operations include the following:

·                  Wastewater Discharge.  Section 402 of the CWA creates a process for establishing effluent limitations for discharges to streams that are protective of water quality standards through the National Pollutant Discharge Elimination System (“NPDES”), and corresponding programs implemented by state regulatory agencies.  Regular monitoring, reporting and compliance with performance standards are preconditions for the issuance and renewal of NPDES permits that govern discharges into waters of the U.S.  Failure to comply with the CWA or NPDES permits can lead to the imposition of significant penalties, litigation, compliance costs and delays in coal production. Furthermore, the imposition of future restrictions on the discharge of certain pollutants into waters of the U.S. could increase the difficulty of obtaining and complying with NPDES permits, which could impose additional time and cost burdens on our operations.  For instance, waters that states have designated as impaired (i.e., as not meeting present water quality standards) are subject to Total Maximum Daily Load regulations, which may lead to the adoption of more stringent discharge standards for our coal mines and could require more costly treatment.

Likewise, when water quality in a receiving stream is better than required, states are required to conduct an anti-degradation review before approving discharge permits. Anti-degradation policies may increase the cost, time and difficulty associated with obtaining and complying with NPDES permits and may require more costly treatment.

·                  Dredge and Fill Permits.  Many mining activities, including the development of settling ponds and other impoundments, require a Section 404 permit from the Army Corps of Engineers (the “Corps”).  Generally speaking, these Section 404 permits allow the placement of fill materials into navigable waters of the U.S. including wetlands, streams, and other regulated areas.  The Corps has issued general “nationwide” permits for specific categories of activities that are similar in nature and that are determined to have minimal adverse effects on the environment. Permits issued pursuant to Nationwide Permit 21 (“NWP 21”) generally authorize the disposal of dredged or fill material from surface coal mining activities into waters of the U.S., subject to certain restrictions.  NWP 21s are typically reissued for a five-year period and require appropriate mitigation, and permit holders must receive explicit authorization from the Corps before proceeding with proposed mining activities.  The Corps reauthorized use of NWP 21 for surface coal mines in January 2017.  The new NWP 21 closely mirrors the 2012 NWP 21, but removes a provision authorizing disposal of dredged or fill material from certain surface coal mining activities that were previously authorized by the 2007 NWP 21 and clarifies that any losses of stream bed are applied to the 1/2-acre limit for loss of jurisdictional wetlands and waters.  Expansion of our mining operations into new areas may trigger the need for individual Corps approvals, which could be more costly and take more time to obtain.

·                  Considerable legal uncertainty exists surrounding the standard for what constitutes jurisdictional waters and wetlands subject to the protections and requirements of the Clean Water Act. A 2015 rulemaking by EPA to revise the standard was stayed nationwide by the U.S. Court of Appeals for the Sixth Circuit and stayed for certain primarily western states by a United States District Court in North Dakota. In January 2018, the Supreme Court determined that the circuit courts do not have jurisdiction to hear challenges to the 2015 rule, removing the basis for the Sixth Circuit to continue its nationwide stay. Additionally, EPA has promulgated a final rule that extends the applicability date of the 2015 rule for another two years in order to allow EPA to undertake a rulemaking on the question of what constitutes a water of the United States. In the meantime, judicial challenges to the 2015 rulemaking are likely to continue to work their way through the courts along with challenges to the recent rulemaking that extends the applicability date of the 2015 rule. For now, EPA and the Corps will continue to apply the existing standard for what constitutes a water of the United States as determined by the Supreme Court in the Rapanos case and post-Rapanos guidance. Should the 2015 rule take effect, or should a different rule expanding the definition of what constitutes a water of the United States be promulgated as a result of EPA and the Corps’s rulemaking process we could face increased costs and delays due to additional permitting and regulatory requirements and possible challenges to permitting decisions.

·                  Cooling Water Intake.  In May 2014, the EPA issued a new final rule pursuant to Section 316(b) of the CWA that affects the cooling water intake structures at power plants in order to reduce fish impingement and entrainment.  The rule is expected to affect over 500 power plants.  These requirements could increase our customers’ costs and may adversely affect the demand for coal, which may materially impact our results or operations.

Resource Conservation and Recovery Act

The EPA determined that coal combustion residues (“CCR”) do not warrant regulation as hazardous wastes under the Resource Conservation and Recovery Act (“RCRA”) in May 2000. Most state hazardous waste laws do not regulate CCR

18

Table of Contents

as hazardous wastes.  The EPA also concluded that beneficial uses of CCR, other than for mine filling, pose no significant risk and no additional national regulations of such beneficial uses are needed.  However, the EPA determined that national non-hazardous waste regulations under RCRA are warranted for certain wastes generated from coal combustion, such as coal ash, when the wastes are disposed of in surface impoundments or landfills or used as minefill.  In December 2014, the EPA finalized regulations that address the management of coal ash as a non-hazardous solid waste under Subtitle D.  The rules impose engineering, structural and siting standards on surface impoundments and landfills that hold coal combustion wastes and mandate regular inspections.  The rule also requires fugitive dust controls and imposes various monitoring, cleanup, and closure requirements.  There have also been several legislative proposals that would require the EPA to further regulate the storage of CCR.  For example, in December 2016, Congress passed the Water Infrastructure Improvements for the Nation Act, which allows states to establish permit programs to regulate the disposal of CCR units in lieu of the EPA’s CCR regulations.  These requirements, as well as any future changes in the management of CCR, could increase our customers’ operating costs and potentially reduce their ability or need to purchase coal.  In addition, contamination caused by the past disposal of CCR, including coal ash, can lead to material liability for our customers under RCRA or other federal or state laws and potentially further reduce the demand for coal.

Comprehensive Environmental Response, Compensation and Liability Act

The Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”) and similar state laws affect coal mining operations by, among other things, imposing cleanup requirements for threatened or actual releases of hazardous substances into the environment.  Under CERCLA and similar state laws, joint and several liability may be imposed on hazardous substance generators, site owners, transporters, lessees and others regardless of fault or the legality of the original disposal activity.  Although the EPA currently excludes most wastes generated by coal mining and processing operations from the primary hazardous waste laws, such wastes can, in certain circumstances, constitute hazardous substances for the purposes of CERCLA.  In addition, the disposal, release or spilling of some products used by coal companies in operations, such as chemicals, could trigger the liability provisions of CERCLA or similar state laws.  Thus, we may be subject to liability under CERCLA and similar state laws for coal mines that we currently own, lease or operate or that we or our predecessors have previously owned, leased or operated, and sites to which we or our predecessors sent hazardous substances.  We may be liable under CERCLA or similar state laws for the cleanup of hazardous substance contamination and natural resource damages at sites where we control surface rights.  These liabilities could be significant and materially and adversely impact our financial results and liquidity.

Endangered Species Act

The federal Endangered Species Act (the “ESA”) and counterpart state legislation protect species threatened with possible extinction. The U.S. Fish and Wildlife Service (the “USFWS”) works closely with the OSM and state regulatory agencies to ensure that species subject to the ESA are protected from mining-related impacts.  A number of species indigenous to the areas in which we operate are protected under the ESA.  Other species in the vicinity of our operations, such as the mountain plover, which the USFWS determined not to list as threatened in May 2011, may have their listing status reviewed in the future.

Compliance with ESA requirements could have the effect of prohibiting or delaying us from obtaining mining permits.  These requirements may also include restrictions on timber harvesting, road building and other mining or agricultural activities in areas containing the affected species or their habitats.  For example, our Spring Creek Mine applied for a lease modification under the BLM leasing regulations and a mine permit amendment to add lands to the permit area.  Portions of these lands have been designated as core habitat for the greater sage grouse by the Montana Fish, Wildlife and Parks Department. While the USFWS has determined that the greater sage grouse should not be listed as a threatened or endangered species, the BLM has developed Conservation Plans designed to preserve and protect greater sage-grouse habitat.  Montana has also developed sage grouse conservation plans through the Montana Governor’s executive order.  Our approvals to mine or otherwise affect these areas will be subject to review by the BLM and the Montana Department of Environmental Quality and determinations of our ability to adequately mitigate impacts to sage grouse and sage grouse habitat. The plans do however, recognize the right to mine where there are valid existing rights. The BLM has stated that conserving sagebrush habitat will be an important consideration in the BLM review of proposed coal mines or coal mine expansions. The plans also recommend that the Secretary of the Interior withdraw 10 million acres from hardrock mining for up to 20 years. The BLM is beginning that separate, public withdrawal process by putting in place a temporary, two-year prohibition for new hardrock mining location and entry in certain areas. Our mines are not located within the areas that the BLM has designated for withdrawing from hardrock mining.

These and any similar future actions could result in more stringent requirements being issued by the BLM and other agencies involved in the leasing and permitting process.  The USFWS must review its 2015 decision to not list the sage

19

grouse again in 2020.  Should more stringent protective measures be applied or if the greater sage-grouse is listed as a threatened species by the USFWS, this could significantly impair our ability to conduct our mining operations or result in increased operating costs, heightened difficulty in obtaining future mining permits, or the need to implement additional mitigation measures.

Use of Explosives

Our surface mining operations are subject to numerous regulations relating to blasting activities.  Pursuant to these regulations, we incur costs to design and implement blast schedules and to conduct pre-blast surveys and blast monitoring.  In addition, the storage of explosives is subject to regulatory requirements.  For example, pursuant to a rule issued by the Department of Homeland Security in 2007, facilities in possession of chemicals of interest (including ammonium nitrate at certain threshold levels) are required to complete a screening review.  Our mines are low risk, Tier 4 facilities that are not subject to additional security plans.  In 2008, the Department of Homeland Security proposed regulation of ammonium nitrate under the ammonium nitrate security rule.  Many of the requirements of the rule would be duplicative of those in place under the Bureau of Alcohol Tobacco and Firearms, including registration and background checks.  Additional requirements may include tracking and verifications for each transaction related to ammonium nitrate.  A final rule has yet to be issued.  In December 2014, the OSM announced its decision to pursue a rulemaking to revise regulations under SMCRA, which will address all blast generated fumes and toxic gases.  OSM has not yet issued a proposed rule to address these blasts, and it is unclear if or when a proposed rule will be issued.  The outcome of these rulemakings could materially adversely impact our cost or ability to conduct our mining operations.

National Environmental Policy Act

NEPA requires federal agencies, including the Department of the Interior, to evaluate major agency actions that have the potential to significantly impact the environment, such as issuing a permit or other approval. In the course of such evaluations, an agency will typically prepare an environmental assessment to assess the potential direct, indirect and cumulative impacts of a proposed project. Where the activities in question have significant impacts to the environment, the agency must prepare an EIS. Compliance with NEPA can be time-consuming and may result in the imposition of mitigation measures that could affect our mining costs and the amount of coal that we are able to produce from mines on federal lands, and may require public comment. Whether agencies have complied with NEPA is subject to protest, appeal or litigation, which can delay or halt projects. The NEPA review process, including potential disputes regarding the level of evaluation required for climate change impacts, may extend the time and/or increase the costs and difficulty for obtaining necessary governmental approvals, and may lead to litigation regarding the adequacy of the NEPA analysis, which could delay or potentially preclude the issuance of approvals or grant of leases.

Other Environmental Laws

We are required to comply with numerous other federal, state and local environmental laws and regulations in addition to those previously discussed.  These additional laws include, for example, the Safe Drinking Water Act, and the Toxic Substances Control Act and transportation laws adopted to ensure the appropriate transportation of our coal both nationally and internationally.  Laws, regulations, and treaties of other countries may also adversely impact our export sales by reducing demand for PRB coal, or coal in general, as a source of power generation in those countries.

Federal Power Act — Grid Reliability Proposal

Pursuant to a directive from the Secretary of the Department of Energy, in 2017, the Federal Energy Regulatory Commission (“FERC”) issued a notice of proposed rulemaking under the Federal Power Act regarding the valuation by regional electric grid system operators of the reliability and resilience attributes of electricity generation.  The rulemaking would have required the FERC to impose market rules that would allow certain cost recovery by electricity-generating units that maintain a 90-day fuel supply on-site and that are therefore capable of providing electricity during supply disruptions from emergencies, extreme weather or natural or man-made disasters.  Many coal-fired electricity generating plants could have qualified under this criteria and the cost recovery could have helped improve the economics of their operations.  However, in January 2018, the FERC terminated the proposed rulemaking, finding that it failed to satisfy the legal requirements of section 206 of the Federal Power Act, and initiated a new proceeding to further evaluate whether additional FERC action regarding resilience is appropriate. Should a version of this rule be adopted along the lines originally proposed, it could provide economic incentives for companies that produce electricity from coal, among other fuels, which could either slow or stabilize the trend in retiring coal-fired power plants and could thereby maintain certain levels of domestic demand for coal.  We cannot speculate on the timing or nature of any subsequent FERC or grid operator actions resulting from FERC’s decision to further study the issue of grid resiliency.

Item 1A.  Risk Factors.

You should carefully consider the risk factors described below and other information contained in this Form 10-K.  If any of the following risk factors, as well as other risks and uncertainties that are not currently known to us or that we currently believe are not material, actually occur, our business, financial condition and results of operations could be materially adversely affected and you may lose all or a significant part of your investment.

Risks Related to Our Business and Industry

Numerous political and regulatory authorities, along with well-funded environmental activist groups, are devoting substantial resources to anti-coal activities to minimize or eliminate the use of coal as a source of electricity generation, domestically and internationally, thereby further reducing the demand and pricing for coal, including PRB coal, and potentially materially and adversely impacting our future financial results, liquidity and growth prospects.

Concerns about the environmental impacts of coal combustion, including perceived impacts on global climate issues, are resulting in increased regulation of coal combustion in many jurisdictions, unfavorable lending policies by government-backed lending institutions and development banks toward the financing of new overseas coal-fueled power plants and divestment efforts affecting the investment community, which could significantly affect demand for our products or our securities. Global climate issues continue to attract public and scientific attention. Numerous reports, such as the Fourth and Fifth Assessment Report of the Intergovernmental Panel on Climate Change, have also engendered concern about the impacts of human activity, especially fossil fuel combustion, on global climate issues. In turn, increasing government attention is being paid to global climate issues and to emissions of GHGs, including emissions of carbon dioxide from coal combustion by power plants. The 2015 Paris climate summit agreement resulted in voluntary commitments by numerous countries to reduce their GHG emissions, and could result in additional firm commitments by various nations with respect to future GHG emissions.  These commitments could further disfavor coal-fired generation, particularly in the medium- to long-term.

Enactment of laws or passage of regulations regarding emissions from the combustion of coal by the United States, some of its states or other countries, or other actions to limit such emissions, could also result in electricity generators further switching from coal to other fuel sources or additional coal-fueled power plant closures.  Further, policies limiting available financing for the development of new coal-fueled power plants could adversely impact the global demand for coal in the future.

There have also been efforts in recent years affecting the investment community, including investment advisors, sovereign wealth funds, public pension funds, universities and other groups, promoting the divestment of fossil fuel equities and pressuring lenders to limit funding to companies engaged in the extraction of fossil fuel reserves.  In California, for example, legislation was signed into law in October 2015 that required California’s state pension funds to divest investments in companies that generate 50% or more of their revenue from coal mining by July 2017.  More recently, in December 2017, the Governor of New York announced that the New York Common Fund will immediately cease all new investments in entities with “significant fossil fuel activities,” and the World Bank announced that it will no longer finance upstream oil and gas after 2019, except in “exceptional circumstances.”  Other activist campaigns have urged banks to cease financing coal-driven businesses.  As a result, numerous major banks have enacted such policies.  The impact of such efforts may adversely affect the demand for and price of securities issued by us, and impact our access to the capital and financial markets.

Additional regulatory developments have been oriented at increasing the regulatory burden associated with mining coal and coal-fired generation.  Regulatory initiatives proposed, adopted, or enacted in the United States by previous administrations include: the MATS rule, the national emission standards for hazardous air pollutants boiler rules, the new source performance standards for fossil-fuel fired power plants, revisions to the nitrogen oxide and sulfur dioxide NAAQS, the CAIR rule, the Clean Power Plan, the regional haze program, regulation of CCR, revisions to the Corps’ Section 404 permitting regime, and OSM’s stream protection rule. See Item 1 “Business—Environmental and Other Regulatory Matters.”   Although the current administration is seeking to unwind many of these initiatives including through a series of executive orders and new regulations, any such actions are subject to judicial review in which the current administration may not prevail, and a future administration may adopt a different approach and pursue further rulemakings to undo or revise any such regulations. These and other governmental actions that directly or indirectly affect the coal mining industry and coal-fired power generation have made, and will continue to make, it more difficult and costly to mine and ship coal, and operate coal-fired assets.  Meanwhile, substantial government subsidies are available to fund various aspects of renewable power generation and supply, which may hurt our ability to compete against these alternative forms of electric generation.

In addition, several well-funded, non-governmental organizations have explicitly undertaken campaigns to minimize or eliminate the use of coal as a source of electricity generation.  For example, the goals of Sierra Club’s “Beyond Coal” campaign include retiring one-third of the nation’s coal-fired power plants by 2020, replacing retired coal plants with “clean energy solutions,” and “keeping coal in the ground.”  It has been reported that the Beyond Coal campaign has been funded by several high-profile, high-net-worth individuals and organizations, including approximately $80 million from Michael Bloomberg and his philanthropic foundation, Bloomberg Philanthropies.  In an effort to stop or delay coal mining activities, the Sierra Club and other activist groups have brought, and continue to bring, numerous lawsuits, including against the BLM to challenge not only the issuance of individual coal leases, but also the federal coal leasing program more broadly.  Other lawsuits continue to be brought challenging historical and pending regulatory approvals, permits and processes that are necessary to conduct coal mining operations or to operate coal-fueled power plants, including so-called “sue and settle” lawsuits where regulatory authorities in the past have reached private agreements with environmental activists that often involve additional regulatory restrictions or processes being implemented without formal rulemaking.

The net effect of these and other similar developments is to make it more costly and difficult to maintain our business and to continue to depress demand and pricing for our coal.  A substantial or extended decline in the prices we receive for our coal due to these or other factors could further reduce our revenue and profitability, cash flows, liquidity, and value of our coal reserves and result in losses.

Coal prices are subject to change based on a number of factors and thermal coal prices are currently depressed.  If thermal coal prices remain depressed, or if there is a substantial or extended decline in prices, it could materially reduce our revenue and profitability, cash flows, liquidity, and value of our coal reserves and result in losses.

Our revenue, results of operations, and the value of our coal reserves depend on the prices we receive for our coal and logistics services.  Over the last several years, prices for thermal coal have become more volatile and depressed due to an oversupply of coal and significantly reduced demand in the U.S. and various other countries.  The prices we receive for our coal and logistics services depend upon factors beyond our control, including:

·                  domestic and foreign supply and demand for coal, including Asian and other foreign demand for PRB coal exports, and the impact of domestic and foreign government environmental, energy and tax policies and currency exchange rate fluctuations;

·                  domestic and foreign demand for electricity and steel;

·                  domestic and foreign economic conditions;

·                  the quantity, quality, and price of coal available from domestic and foreign competitors, including coal re-sellers and traders;

·                  competition for production of electricity from non-coal sources, including the price and availability of alternative fuels, such as natural gas and crude oil, and alternative energy sources, such as nuclear, hydroelectric, wind and solar power, and the effects of technological developments related to these non-coal and alternative energy sources;

·                  adverse weather, climatic or other natural conditions, including natural disasters;

22

Table of Contents

·                  legislative, regulatory and judicial developments, environmental regulatory changes, or changes in energy and tax policy and energy conservation measures that would adversely affect the coal or utility industries, such as legislation or regulation that limits carbon dioxide or sulfur dioxide emissions or provides for increased funding, subsidies or other incentives for, or mandates the use of, alternative energy sources to address climate change;

·                  shareholder activism or activities by non-governmental organizations to restrict the use of coal;

·                  domestic and foreign governmental regulations and taxes, including with respect to air emission standards for coal-fired power plants, and the ability of coal-fired power plants to economically meet these standards;

·                  changes in coal-fired power plant capacity and utilization, including the extent to which new coal plants are built in the United States and other countries;

·                  market price fluctuations for sulfur dioxide emission allowances;

·                  the capacity of, cost of, and proximity to, rail transportation and terminal facilities and rail and terminal performance; and

·                  the other risks described in this Item 1A.

If thermal coal prices remain depressed, or if there is a substantial or extended decline in the prices we receive for our coal and logistics services due to these or other factors, it could materially reduce our revenue and profitability, cash flows, liquidity, and value of our coal reserves and result in losses.

Competition with domestic and foreign coal producers, with traders and re-sellers of coal and with producers of natural gas and other competing energy sources may continue to negatively affect our sales volumes and our ability to sell coal at a favorable price.

The coal industry is highly competitive.  We compete with other domestic and many foreign coal producers, with traders and re-sellers of coal and with other energy producers throughout the U.S. and, for our export sales, internationally.  In addition to the price of coal, coal quality, and transportation costs, demand for coal also has a significant impact on our ability to compete domestically and internationally for coal sales.  Demand for coal depends upon a number of factors, including:

·                  general economic conditions and weather patterns, both of which are significant contributors to the demand for electricity;

·                  delivered prices for coal, including the relative costs of transportation, such as ocean freight rates, from our mine site and competing mines or supplies of coal;

·                  availability and cost of alternative fuel sources, such as natural gas;

·                  technological developments;

·                  environmental, tax, and other governmental policies and regulations, including EPA regulations; and

·                  currency exchange rate fluctuations impacting our export sales.

Demand for U.S. coal has fluctuated over the last decade because of these and other factors and, in recent years, has declined substantially due to global climate change initiatives and other regulatory initiatives that favor natural gas or non-fossil fuel sources of electricity generation, sustained low natural gas prices in the United States, weak global economic conditions and other factors, including those described in this Item 1A.  A decline in domestic demand for coal, or a decline in foreign demand for U.S. coal, has caused, and could continue to cause, additional significant competition among coal producers and downward pressure on coal prices.  Furthermore, overcapacity and increased production in the future, similar to the activities that occurred during the mid-1970s and early 1980s, could result in additional production capacity throughout the industry, causing increased competition and lower coal prices, materially reducing our revenue, profitability, cash flows, and liquidity.

23

Table of Contents

In addition to competing with other coal producers, we compete generally with producers of other fuels, such as natural gas.  A decline in the price of natural gas has made natural gas more competitive against coal and resulted in utilities switching from coal to natural gas.  Sustained low natural gas prices may also cause utilities to continue to phase out or close existing coal-fired power plants or reduce or eliminate construction of any new coal-fired power plants, which could have a material adverse effect on demand and prices received for our coal.

Government action requiring the use and dispatch of alternative energy sources and fuels or providing financing or incentives to encourage continuing technological advances and deployment in this area could further enable alternative energy sources to become more competitive with coal.  If alternative energy sources, such as hydroelectric, wind or solar, continue to become more cost-competitive, demand for coal could decrease and cause a decrease in the price of coal.

If we do not grow our longer term logistics revenue and export sales at favorable prices, we may incur losses in our logistics business and be subject to significant take-or-pay commitments.

Our ability to grow our export sales revenue and logistics margins depends on a number of factors, including the price we receive for our coal and our logistics services, the existence of sufficient and cost-effective export terminal capacity for the shipment of thermal coal to foreign customers, and demand by customers in Asia and in other potential export destinations for PRB coal.

International customer demand for PRB coal, and the prices those customers may be willing to pay for PRB coal and related transportation services provided by our logistics business, can be affected by a variety of factors, including supplier diversity and security considerations, economic conditions and demand for electricity in the relevant locations, international energy and tax policies and regulatory requirements, and availability and pricing for thermal coal delivered from alternative international coal basins.  Further, our export sales are priced relative to various international coal indices adjusted for energy content and other quality and delivery criteria.  These indices are volatile and heavily influenced by Chinese and Indian thermal coal import demand.  For example, over the last five years, Newcastle prices have varied from a high of $109.69 per tonne to a low of $47.37 per tonne.  Similarly, Kalimantan 5000 prices have varied from a high of $77.00 per tonne to a low of $36.80 per tonne.  Fluctuations in these indices may be affected by a wide range of international supply and demand factors, including those listed above.  Our export sales may also be negatively impacted by currency exchange rate fluctuations that make coal from other countries more economical than PRB coal and provide competitive advantages to non-U.S. producers when the U.S. dollar is strong in comparison to those foreign currencies.  For example, the Newcastle and Kalimantan 5000 benchmark price indices are denominated in U.S. dollars.  If demand for exports declines or we are unable to secure a favorable price for the export of our coal and logistics services, our cash flows, profitability, liquidity, and results of operations may be materially adversely affected.

At present, there is limited terminal capacity for the export of PRB coal to foreign destinations.  Our access to existing and any future terminal capacity, including the proposed MBT in which we have an option for potential future capacity, may be adversely affected by regulatory and permit requirements, environmental and other legal challenges, public perceptions and resulting political pressures, operational issues at terminals and competition among North American coal producers for access to limited terminal capacity, among other factors.  If we fail to maintain terminal capacity, or are denied access to existing or any future terminals for the export of our coal on commercially reasonable terms, or at all, our results from our future export transactions will be materially adversely affected.

In addition, we have significant multi-year take-or-pay contracts for rail and terminal capacity related to our logistics services for export sales.  These contracts require us to pay for a minimum quantity of coal to be transported on the railway or through the terminal regardless of whether we sell any coal or the prices we receive for our coal or logistics services.  If we fail to make sufficient export sales to meet our minimum obligations under these take-or-pay contracts, we are still obligated to make payments to the railway or terminal, which could have a negative impact on our cash flows, profitability and results of operations.  As of December 31, 2017, we had take-or-pay commitments of $45.7 million that could be potentially payable if we fail to meet our minimum shipment obligations.  See Item 7—“Management’s Discussion and Analysis of Financial Condition and Results of Operations—Contractual Obligations.”

The regulatory environment may also adversely impact our logistics business and future export sales.  For example, the ONRR previously finalized changes to how coal royalties are calculated for sales to affiliated entities, which could have adversely impacted export sales for vertically integrated mining and logistics entities, such as our logistics business, and placed vertically integrated entities at a competitive disadvantage compared to independent coal brokers.  Moreover, the ONRR proposal included a so-called “default provision”, which would have created further uncertainty as to how the ONRR would apply its proposed royalty rules to our export sales.  We, along with other energy industry companies and trade associations, filed litigation to challenge this ONRR rule.  The current administration delayed the effective date of the rule in

24

Table of Contents

February 2017 before ultimately rescinding the rule in August 2017. The states of California and New Mexico have filed a legal challenge to the rescission of the ONRR rule in a federal district court in California and are seeking the reinstatement of the rule formerly adopted by the Obama administration.  Should the plaintiffs prevail in this litigation and obtain an order vacating the rescission of the ONRR rule, or should a similar rule be promulgated by this or a future administration, our business and revenues may be adversely affected.

Our long-term growth may be materially adversely impacted if economic, commercially available carbon capture technology for power plants is not developed and adopted in a timely manner.

Federal or state laws or regulations may be adopted that would impose new or additional limits on the emissions of GHGs, including, but not limited to, CO2 from electric generating units using fossil fuels such as coal or natural gas.  In order to comply with such regulations, electric generating units using fossil fuels may be required to implement carbon capture technology.  For example, in October 2015, the EPA released a rule that establishes, for the first time, new source performance standards under the federal Clean Air Act for CO2 emissions from new fossil fuel-fired electric utility generating power plants.  The EPA has designated partial carbon capture and sequestration as the best system of emission reduction for newly constructed fossil fuel-fired steam generating units at power plants to employ to meet the standard.  However, there is a risk that such technology, which may include storage, conversion, or other commercial use for captured carbon, may not be commercially practical in limiting emissions as otherwise required by the proposed rule or similar rules that may be proposed in the future.  If such legislative or regulatory programs are adopted, and economic, commercially available carbon capture technology for power plants is not developed or adopted in a timely manner, it would negatively affect our customers and would further reduce the demand for coal as a fuel source, causing coal prices and sales of our coal to decline, perhaps materially.

As a result of ongoing depressed industry conditions and previous coal producer bankruptcy filings, the coal industry has experienced increased credit pressures that could result in demands for credit support by third parties or decisions by banks, surety bond providers, investors or other companies to reduce or eliminate their exposure to the coal industry, including our company.  These credit pressures could materially and adversely impact our liquidity and ability to meet our regulatory requirements.

Ongoing depressed industry conditions and previous coal producer bankruptcy filings have resulted in increased credit pressures on the coal industry.  These credit pressures include, for example, (a) vendors, suppliers, customers and other commercial counterparties seeking prepayments, security deposits, letters of credit and other credit protections, and (b) banks, surety bond providers, investors and other companies reducing or eliminating their exposure to the coal industry.  Although some of these credit pressures may be company-specific, many are directed to the coal industry in general due to the current overall negative investor sentiment toward the industry.  Any credit demands by third parties or refusals by banks, surety bond providers, investors or others to extend, renew or refinance credit on commercially reasonable terms may adversely impact our business, financial condition, results of operations, cash flows and liquidity.  In some cases, such as any collateral requirements imposed by surety bond providers to issue surety bonds that secure our future performance under various federal and state laws, our ability to meet regulatory requirements may also be adversely impacted if we are not able to satisfy cash or other collateral requirements.  As of December 31, 2017, there were approximately $422.9 million in third-party surety bonds outstanding to primarily secure the performance of our reclamation and lease obligations.

Our business, financial condition and results of operations may be adversely affected by unfavorable global or U.S. economic and market conditions.

In recent years, the global economic downturn, particularly with respect to the U.S. economy and various European and Asian economies, and global financial and credit market disruptions had a negative impact on us and the coal industry generally.  For example, the economic downturn in recent years has negatively impacted electricity demand and led to an oversupply of thermal coal and depressed prices.

Furthermore, because we typically seek to enter into long-term arrangements for the sale of a substantial portion of our coal, the average sales price we receive for our coal may lag behind any general economic recovery.  Future economic downturns or further disruptions in the financial and credit markets could negatively impact our business, financial condition and results of operations.

Decreases in U.S. and global demand for electricity due to economic, weather or other conditions could negatively affect coal prices.

Our coal customers primarily use our coal as fuel for electricity generation.  Overall economic activity and the associated demands for power by industrial users can have significant effects on overall electricity demand and can be caused by a number of factors.  An economic slowdown can significantly slow the growth of electricity demand and could result in reduced demand for coal.  For example, declines in the rate of international economic growth in countries such as China, India or other developing countries could further negatively impact the demand for U.S. coal and result in a continuing oversupply of coal.  Weather patterns can also greatly affect electricity demand.  Extreme temperatures, both hot and cold, cause increased power usage and, therefore, increase generating requirements from all sources.  Mild temperatures, on the other hand, result in lower electrical demand, which allows generators to choose the sources of power generation when deciding which generation sources to dispatch.  For example, the unusually warm winter of 2015/2016 led to low natural gas heating demand at a time of high gas production.  This in turn led to low natural gas prices and substitution of gas for coal.  When gas prices rose, this substitution of PRB coal decreased, but not enough to offset the increased utility coal stockpiles during this period, which lead to a reduction in utility coal contracting and depressed thermal coal prices.  Decreases in coal demand for these or other reasons could cause further downward pressure on coal prices and would negatively impact our results of operations.

Our coal mining operations are subject to operating risks, which could result in materially increased operating expenses and decreased production levels.

We mine coal at surface mining operations located in Wyoming and Montana.  Our coal mining operations are subject to a number of operating risks.  These operating risks include, among others:

·                  poor mining conditions resulting from geological, hydrologic, ground or other conditions, which may cause instability of highwalls or spoil-piles or cause damage to nearby infrastructure such as roads, power lines, railways and gas pipelines;

·                  critical mining and plant equipment failures, unexpected maintenance problems or damage from fire, flooding or other events;

·                  adverse weather and natural disasters, such as heavy rains, flooding, droughts, dust and other natural events affecting operations, transportation or customers;

·                  the unavailability of raw materials, equipment (including heavy mobile equipment) or other critical supplies such as tires and explosives, fuel, lubricants and other consumables of the type, quantity and/or size needed to meet production expectations;

·                  the capacity of, and proximity to, rail transportation facilities and rail transportation delays or interruptions, including derailments;

·                  competition and/or conflicts with other natural resource extraction activities and production within our operating areas, such as coalbed methane extraction or oil and gas development; and

·                  a major incident at a mine site that causes all or part of the operations of a mine to cease for some period of time.

Because we maintain very little produced coal inventory, disruptions in our operations due to these or other risks could negatively impact or even halt production and shipments, significantly increase the cost of mining and impact our ability to meet our contractual obligations to customers and others, which could have a material adverse effect on our results of operations.  We maintain insurance policies that provide limited coverage for some of these risks, although there can be no assurance regarding the extent, if any, to which these risks would be covered by our insurance policies.

The availability and reliability of sufficient transportation capacity and increases in transportation costs could materially adversely affect the demand for our coal or impair our ability to supply coal to our domestic and export customers.

Transportation costs represent a significant portion of the total cost of coal for our domestic and export customers.  The cost and availability of transportation is a key factor in a customer’s purchasing decision and impacts our coal sales and the price we receive for our coal.  Coal could become a less competitive source of energy if the costs of transportation

26

Table of Contents

increase or the availability or capacity of rail lines or export terminals is insufficient.  Transportation costs and availability could also make our coal less competitive than coal produced from other regions.

Our ability to sell coal to our customers depends primarily upon third-party rail systems and export terminals.  If our customers are unable to obtain transportation services, or to do so on a cost-effective basis, our business and growth strategy could be adversely affected.  Alternative transportation and delivery systems are generally inadequate and not suitable to handle the quantity of our shipments or to ensure timely delivery to our customers.  Existing and proposed export terminals are also subject to permit requirements and challenges from environmental organizations which may make it complicated or expensive to expand existing terminal capacity or open new export terminals in a timely and cost-effective manner.  In addition, much of the PRB is served by two rail carriers, and the Northern PRB is only serviced by one rail carrier.  The loss of sufficient and reliable access to rail capacity in the PRB, as we have experienced in recent years, could create disruption until this access was restored; significantly impairing our ability to supply coal and resulting in materially decreased revenue.  Similarly, being denied access to an export terminal could significantly affect our future export sales, materially decreasing our logistics revenue and growth opportunities.  Our ability to open new mines or expand existing mines may also be affected by the access to, and availability and cost of rail, export terminal or other transportation systems available for servicing these mines.

Typically, our mine customers contract and pay directly for transportation of coal from the mine or port to the point of use.  However, for contracts with our logistics customers, we are required to enter into transportation agreements pursuant to which we arrange and pay for all rail transport, terminal, and for our international customers, demurrage charges.  As the volume of deliveries coordinated to customer contracted destinations increases, so do our costs and risks.  Our ability to supply coal to our customers and our customers’ ability to take our coal may be impacted by the disruption of these transportation services because of weather-related problems; mechanical difficulties; maintenance shut-downs; environmental, political and regulatory issues; train derailment; bridge or structural concerns; infrastructure damage, whether caused by ground instability, accidents or otherwise; strikes; lock-outs; lack of fuel or maintenance items; fuel costs; accidents; terrorism or domestic catastrophe or other events.  For example, in the spring and summer of 2011, the Midwest region experienced severe flooding which disrupted rail service to mines in the PRB and affected the ability of those customers who were impacted by the flooding to take coal deliveries.  During 2014, we also experienced rail interruptions due to increased competition for rail crews from crude oil and grain shipments, which negatively impacted our shipments and financial results.  Any similar disruption in the future could negatively impact our results of operations.  In addition, some scientists have opined that increasing concentrations of GHGs in the Earth’s atmosphere may produce climate changes that have significant physical effects, such as increased frequency and severity of storms, droughts and floods and other climatic events. If any such effects were to occur in areas where we or our clients operate, they could have an adverse effect on our assets and operations.

If we are unable to acquire or develop additional coal reserves that are economically recoverable, our future profitability may be reduced and our future success and growth may be significantly impacted.

Our profitability depends substantially on our ability to mine, in a timely and cost-effective manner, coal reserves that possess the quality characteristics our customers’ desire.  Because our reserves decline as we mine our coal, our future success and growth depend upon our ability to acquire additional coal that is economically recoverable.  We primarily acquire additional coal through the federal competitive leasing process, but we also enter into state and private coal leases as well as acquire coal from private third parties.  If we fail to acquire or develop additional reserves, our existing reserves will eventually be depleted.  Our ability to obtain additional coal reserves in the future could also be limited by a number of factors, any of which could impact our business and growth strategy, including:

·                  the availability of cash we generate from our operations;

·                  available financing and restrictions under our debt instruments;

·                  competition from other coal companies for properties;

·                  lack of suitable acquisition or LBA opportunities;

·                  delays or changes in the federal leasing process due to third-party legal challenges, regulatory developments or climate change initiatives; or

·                  the inability to acquire coal properties or federal coal leases on commercially reasonable terms.

Table of Contents

Any significant delay in acquiring reserves could negatively impact our production rate.  We will need to acquire additional coal reserves that can be mined on an economically recoverable basis to maintain our production capacity and competitive position.  We may be unable to mine future reserves at profitability levels achieved at times in the past.  The price we receive for our coal also impacts how economically we can recover our existing coal.  Our ability to develop economically recoverable reserves will be materially adversely impacted if prices for thermal coal sold remain depressed or decrease significantly.

Because most of the coal in the vicinity of our mines is owned by the U.S. federal government, our future success and growth would be affected if we are unable to acquire or are significantly delayed in the acquisition of additional reserves through the federal competitive leasing process, including due to third party legal challenges or changes in the federal coal leasing program.

The U.S. federal government owns most of the coal in the vicinity of our mines.  Accordingly, the federal competitive leasing process is our primary means of acquiring additional reserves.  There is no requirement that the federal government must lease its coal or give preference to any LBA applicant, which means our bids for federal coal leases may compete with other coal producers’ bids.  Federal coal leases are expensive to obtain and the review process to submit an LBA for bid continues to lengthen.  We expect this trend to continue.  The size of potential LBA tracts may also make it easier for new mining operators to enter the market on economic terms and may, therefore, further increase competition for federal coal leases.  In order to win a lease in the LBA process and acquire additional coal, our bid for a coal tract must meet or exceed the fair market value of the coal based on the internal estimates of the BLM, which are not published.  Any failure or delay in acquiring a coal lease through the LBA process, or the inability to do so on economic terms, could cause our production to decline, materially adversely affecting our business, cash flows and results of operations.

Increased opposition from non-governmental organizations and other third parties may also lengthen, delay or adversely impact the LBA process, which may result in difficulties in obtaining leases or impact our ability to mine the coal subject to those leases and/or delay our access to mine the coal.  See Note 17 of Notes to Consolidated Financial Statements in Item 8 for a discussion regarding certain challenges by environmental activist groups against potential lease modifications and other regulatory processes relating to our mines.

The LBA process also requires us to acquire rights to mine from certain surface owners overlying the coal before the federal government will agree to lease the coal.  Surface rights in the PRB are becoming increasingly more difficult and costly to acquire.  Certain federal regulations provide a specific class of surface owners, also known as QSO, with the ability to prohibit the BLM from leasing its coal.  For example, in connection with an LBA that we previously nominated for our Cordero Rojo Mine, the BLM indicated that certain surface owners satisfy the regulatory definition of QSO.  If a QSO owns the land overlying a coal tract, federal laws prohibit us from leasing the coal tract without first securing surface rights to the land, or purchasing the surface rights from the QSO.  This right of QSOs allows them to exercise significant influence over negotiations to acquire surface rights and can delay the LBA process or ultimately prevent the acquisition of coal underlying their surface.  If we are unable to successfully negotiate access rights with QSOs at a price and on terms acceptable to us, we may be unable to acquire federal coal leases on land owned by the QSO.  Our profitability could be materially adversely affected if the prices to acquire land owned by QSOs increase.

If we are unable to acquire surface rights to access our coal, we may be unable to obtain a permit or otherwise be unable to mine coal we own and may be required to employ expensive techniques to mine around those sections of land we cannot access in order to access other sections of coal reserves.

After we acquire coal, we are required to obtain a permit to mine the coal through the applicable state agencies before we are allowed to begin mining.  In part, the permitting requirements provide that, under certain circumstances, we must obtain surface owner consent if the surface estate has been split from the mineral estate, which is commonly known as a “split estate.” We have in the past and may in the future be required to negotiate with multiple parties for the surface access that overlies coal we acquired.  If we are unable to successfully negotiate surface access with any of these surface owners, or do so on commercially reasonable terms, we may be denied a permit to mine some of the coal we have acquired or may find that we cannot mine the coal at a profit or at all.  If we are denied a permit, this would create significant delays and restrictions in our mining operations and materially adversely impact our business and results of operations.  Furthermore, if we determine to alter our plans to mine around the affected areas, we could incur significant additional costs to do so, which could increase our operating expenses considerably and could materially adversely affect our results of operations.  Failure to successfully negotiate access for surface rights overlying coal that we control in a timely manner may also result in significant accounting charges, which could have a material adverse impact on our results of operations.

Defects in title or the loss of a leasehold interest in, or superior or conflicting property rights impacting, reserves or surface rights could limit our ability to mine our coal reserves and adversely impact our operations and costs.

A title defect on any lease, whether private or through a governmental entity, or the surface rights related to any of our reserves could adversely affect our ability to mine the associated coal reserves.  Consistent with industry practice, we conduct only limited investigations of title to our coal properties prior to leasing.  Title to properties leased from private third parties is not usually fully verified until we make a commitment to develop a property, which may not occur until we have obtained the necessary permits and completed exploration of the property. Title or other defects in surface rights held by us or other third parties could impair our ability to mine the associated coal reserves or cause us to incur unanticipated costs.

In addition, these leasehold interests may be subject to superior property rights of other third parties.  The federal government leases many different mineral rights in addition to coal, such as coalbed methane, natural gas and crude oil rights.  Some of these minerals are located on, or are adjacent to, some of our coal and LBA areas, potentially creating conflicting interests between us and the lessees of those interests and may affect our ability to operate as planned if our title is not superior or cost-effective arrangements cannot be timely negotiated.  We are regularly in negotiations with third parties in an effort to address potentially conflicting mineral development.  These negotiations may not be effective.  In that event, our mine plans, future costs and production rates may be adversely impacted.  Anticipated oil and gas development is expected to continue to increase the frequency of these potential conflicts.

Further, the majority of our coal interests are acquired by lease from state or federal governments.  If any of our leases are terminated, for lack of diligent development or otherwise, we would be unable to mine the affected coal and our business and results of operations could be materially adversely affected.

We may not recover our investments in our mining, exploration, port access rights, development projects, and other assets, which may require us to recognize impairment charges related to those assets.

The value of our assets may be adversely affected by numerous uncertain factors, some of which are beyond our control, including:

·                  unfavorable changes in the economic environments in which we operate;

·                  unfavorable regulatory or legal developments impacting our industry;

·                  lower-than-expected domestic and international demand and coal pricing;

·                  technical and geological operating difficulties;

·                  an inability to economically extract our coal reserves;

·                  unanticipated increases in operating costs;

·                  disputes or difficulties with counterparties for our development projects; and

·                  an inability to obtain additional export terminal capacity due to extensive permit requirements and challenges from environmental organizations.

These may cause us to fail to recover all or a portion of our investments in those assets and may trigger the recognition of impairment charges, which could have a substantial adverse impact on our results of operations.  For example, due to the weak outlook for 8400 Btu coal, we recorded a non-cash impairment charge of $33.4 million related to goodwill at our 8400 Btu Cordero Rojo Mine during the year ended December 31, 2015.  This represented a full write down of the Cordero Rojo Mine’s goodwill.  Additionally, in consideration of consensus projections of weak export pricing, a weak outlook for coal exports, and our associated decision at that time to amend the port and rail contracts to require no export shipments from 2016 through 2018, we determined that the carrying values of certain intangible assets in our Logistics and Related Activities segment were impaired.  Therefore, during the year ended December 31, 2015, we wrote off the full value of our port access rights of $52.2 million and our $6.0 million equity investment in GPT.  During the year ended December 31, 2016, we recorded impairments of $2.6 million, primarily for engineering costs related to the Overland Conveyor project at our Antelope Mine and $2.0 million related to a shovel that we do not expect to use because of declining productions.  Because of the volatile nature of U.S. and international coal demand and pricing, it is reasonably possible that our current

estimates of projected future cash flows from our mining assets may change in the near term, which may result in the need for further adjustments to the carrying value of mineral rights and other assets.

Acquisitions are a potentially important part of our long-term growth strategy and involve a number of risks, any of which could cause us not to realize the anticipated benefits.

Acquisitions are a potentially important part of our long-term growth strategy, and we may pursue acquisition opportunities in the future in the U.S. and other jurisdictions.  If we fail to accurately estimate the future results and value of an acquired business or are unable to successfully integrate the businesses or properties we acquire, our business, financial condition or results of operations could be negatively affected, and we may be unable to grow our business.  Acquisition transactions involve various risks, including:

·                  uncertainties in assessing the strengths and potential profitability, and the related weaknesses, risks, contingent and other liabilities, of acquisition candidates;

·                  changes in business, industry, market or general economic conditions that affect the assumptions underlying our rationale for pursuing the acquisition;

·                  the inability to achieve identified operating and financial synergies anticipated to result from an acquisition;

·                  the potential loss of key customers, management or employees of an acquired business;

·                  the nature and composition of the workforce, including the acquisition of a unionized workforce;

·                  diversion of our management’s attention from other business concerns;

·                  regulatory challenges for completing and operating the acquired business, including opposition from environmental groups or regulatory agencies;

·                  environmental or geological problems in acquired coal properties, including factors that make the coal unsuitable for intended customers (due to ash, heat value, moisture, or contaminants), that make the coal more expensive to mine, or delay our ability to mine;

·                  inability to acquire sufficient surface rights to enable extraction of coal resources;

·                  outstanding permit violations associated with acquired assets;

·                  difficulties or unexpected issues arising from our evaluation of internal control over financial reporting of the acquired business;

·                  risks related to operating in new jurisdictions or industries, including increased exposure to foreign government and currency risks with respect to any international acquisitions; and

·                  unanticipated liabilities associated with the acquired companies.

Any one or more of these factors could cause us not to realize the benefits we might anticipate from an acquisition.  Moreover, any acquisition opportunities we pursue could materially increase our liquidity and capital resource needs and may require us to incur indebtedness, seek equity capital or both.  We may not be able to satisfy these liquidity and capital resource needs on acceptable terms or at all.  In addition, future acquisitions could result in our assuming significant long-term liabilities relative to the value of the acquisitions.

We may be unable to obtain, maintain or renew permits or licenses necessary for our operations, including due to third party legal challenges or climate change-related assessments that are increasingly required as part of our regulatory processes, which would materially reduce our production, cash flows and profitability.

As a mining company, we must obtain a number of permits and licenses from various federal, state and local agencies and regulatory bodies that impose strict regulations on environmental and operational matters in connection with our

30

Table of Contents

coal operations, including restricting the number of tons we may mine under our air quality permits.  We are also subject to strict regulatory requirements and oversight for our Sequatchie Valley reclamation property in Tennessee.  These rules, and the interpretations of these rules, are complex, change frequently and are often subject to discretionary interpretations by the regulators, all of which make compliance more difficult or impractical, and may possibly preclude the continuance of ongoing operations, impact the development of future mining operations, restrict the amount of our production, or subject us to significant fines and penalties.

The public, including non-governmental organizations, anti-mining groups and individuals, have certain statutory rights to comment upon and submit objections to requested permits and EISs prepared in connection with applicable regulatory processes.  These groups may also participate in the permitting and licensing process, including bringing citizens’ lawsuits to challenge the issuance of permits, the validity of an EIS or performance of mining activities, which can create delay and uncertainty in acquiring permits and mining the coal underlying our leases.  Refer to Note 17 of Notes to Consolidated Financial Statements in Item 8 for a discussion regarding certain challenges by environmental activist groups against regulatory permits and approvals for our mines.  These challenges seek to vacate prior regulatory decisions and authorizations that are legally required for some or all of our current or planned mining activities.  If we are required to reduce or modify our mining activities as a result of these challenges, the impact could have a material adverse effect on our shipments, financial results and liquidity, and could result in claims from third parties if we are unable to meet our commitments under pre-existing commercial agreements as a result of any such required reductions or modifications to our mining activities.

If our permits or licenses are not issued or renewed in a timely fashion or at all, or if permits issued or renewed are conditioned in a manner that restricts our ability to efficiently and economically conduct our mining activities, or if we are found to have violated any permitting or regulatory requirements, we could suffer a material reduction in our production, an impairment of our mineral rights, significant fines and penalties, and our cash flows or profitability could be materially adversely affected.

Existing and future legislation, treaties, regulatory requirements and public concerns relating to GHG emissions could negatively affect our customers and further reduce the demand for coal as a fuel source, causing coal prices and sales of our coal to materially decline.

Global climate change initiatives and public perceptions regarding fossil fuels have resulted, and are expected to continue to result, in decreased coal-fired power plant capacity and utilization, phasing out and closing many existing coal-fired power plants, reducing or eliminating construction of new coal-fired power plants in the United States and certain other countries, increased costs to mine coal and decreased demand and prices for thermal coal, including PRB coal. See Item 1 “Business—Environmental and Other Regulatory Matters—Global Climate Change.”

There are three important sources of GHGs associated with the coal industry.  The end use of our coal in electricity generation is the largest of the three sources of GHGs.  Combustion of fuel for mining equipment used in coal production is another source of GHGs.  In addition, coal mining can release methane, a GHG, directly into the atmosphere.  These emissions from coal consumption and production are subject to pending and proposed regulations as part of regulatory initiatives to address global climate change and global warming.  Various international, federal, regional and state proposals are being considered to limit emissions of GHGs, including possible future U.S. treaty commitments, new federal or state legislation that may, among other things establish a cap-and-trade regime, and regulation under existing environmental laws by the EPA and other regulatory agencies.  For example, the United States recently joined nearly 200 other nations in an agreement to voluntarily limit GHG emissions.  Although the United States has since announced its intention to withdraw from the agreement, certain U.S. cities and states have announced their intention to satisfy their proportionate obligations under the agreement.  These and other voluntary pledges could further decrease demand and pricing for our coal.  Future regulation of GHG emissions may require additional controls on, or the closure of, coal-fired power plants and industrial boilers or may restrict the construction of new coal-fired power plants.  For example, the EPA released the CPP, which requires reductions in emissions from existing power plants, as well as new source performance standards for GHG emissions for new coal and oil-fired power plants, which require partial carbon capture and sequestration.  See “Risks Related to Our Business and Industry— Our long-term growth may be materially adversely impacted if economic, commercially available carbon capture technology for power plants is not developed and adopted in a timely manner.”  These regulatory initiatives may increase our costs and decrease demand and pricing for our coal and logistics services, and may lead to increased demand for domestic electricity fired by natural gas because gas-fired plants are cheaper to construct, and permits to construct these plants can be easier to obtain.

The permitting of new coal-fired power plants has also recently been contested, at times successfully, by state regulators and environmental organizations due to concerns related to GHG emissions from the new plants.  Private litigation

31

Table of Contents

has also been brought against industry participants based on GHG-related concerns.  The U.S. Supreme Court held that federal common law provides no basis for public nuisance claims against utilities due to their carbon dioxide emissions, but tort-type liabilities and other GHG-related claims against utilities and energy producers may be asserted.  For example, in 2011 residents and property owners along the Mississippi Gulf coast filed litigation against approximately 90 companies in energy, fossil fuels and chemical industries, including PRB and other domestic coal companies, alleging that the defendants caused the emission of GHGs that contributed to global warming, which in turn caused a rise in sea levels and added to the ferocity of Hurricane Katrina in 2005, which combined to destroy the plaintiffs’ property.  The lawsuit was dismissed by the Federal District Court in 2012 and the dismissal was affirmed by the Fifth Circuit Court of Appeals in May 2013.  However, if other GHG-related litigation, such as the California Climate Change Litigation, is successful, the coal industry and our company may be materially adversely impacted.  For a discussion of the California Climate Change Litigation, see Note 17 of Notes to the Consolidated Financial Statements in Item 8.

Extensive environmental laws, including existing and potential future legislation, treaties and regulatory requirements relating to air emissions, affect our customers and could further reduce the demand for coal as a fuel source and cause coal prices and sales of our coal to materially decline.

The operations of our customers are subject to extensive environmental regulation particularly with respect to air emissions.  For example, CSAPR initially requires 28 states in the Midwest and eastern seaboard of the U.S. to significantly improve air quality by reducing power plant emissions that cross state lines and contribute to ozone and/or fine particle pollution in other states.  In August 2012, the U.S. Court of Appeals for the District of Columbia Circuit vacated CSAPR and ordered the EPA to continue enforcing CAIR.  The U.S. Supreme Court reversed the D.C. Circuit’s vacation of CSAPR, and the D.C. Circuit granted a request by the EPA to lift the stay of the rule.  Subsequently, in November 2014, the EPA issued an interim final rule reconciling the CSAPR rule with the Court’s order to lift the stay, calling for Phase 1 implementation in 2015 and Phase 2 implementation in 2017.  In September 2016, the EPA finalized an update to the CSAPR ozone season program by issuing the Final CSAPR Update.  CSAPR is one of a number of significant regulations that the EPA has issued or expects to issue that will impose more stringent requirements relating to air, water and waste controls on electric generating units.  These rules include the EPA’s requirements for CCR management, which were finalized in December 2014 and further regulate the handling of wastes from the combustion of coal.  In addition, in March 2013, the EPA formally adopted a revised final rule to reduce emissions of toxic air pollutants from power plants.  Specifically, MATS for power plants will reduce emissions from new and existing coal- and oil-fired electric utility steam generating units.  In June 2015, the U.S. Supreme Court struck down the MATS rule based on the EPA’s failure to take costs into consideration and remanded the case back to the D.C. Circuit.  The D.C. Circuit remanded the rule to the EPA.  In April 2016, the EPA issued a final finding that it is appropriate and necessary to set standards for emissions of air toxics from coal- and oil-fired power plants.

Considerable uncertainty is associated with air emissions initiatives.  Under the previous administration, new regulations were in the process of being developed, and many existing and potential regulatory initiatives are subject to review by federal or state agencies or the courts or have been targeted for rescission by the current administration.  Stringent air emissions limitations are either in place or are likely to be imposed in the short to medium term, and these limitations will likely require significant emissions control expenditures for many coal-fired power plants.  As a result, these power plants may switch to other fuels that generate fewer of these emissions or may install more effective pollution control equipment that reduces the need for low-sulfur coal.  Any further switching of fuel sources away from coal, closure of existing coal-fired power plants, or reduced construction of new coal-fired power plants could have a material adverse effect on demand for, and prices received for, our coal.  Alternatively, less stringent air emissions limitations, particularly related to sulfur, to the extent enacted, could make low-sulfur coal less attractive, which could also have a material adverse effect on the demand for, and prices received for, our coal.  See Item 1 “Business—Environmental and Other Regulatory Matters.”

Our mining operations are subject to extensive environmental, health, safety or other laws and regulations that could materially increase our costs or limit our ability to produce and sell coal.

Our mining operations, including our Sequatchie Valley reclamation property in Tennessee, are subject to extensive federal, state and local environmental, health and safety, transportation, labor and other laws and regulations. See Item 1 “Business—Environmental and Other Regulatory Matters.”  Examples include those relating to:

·                  employee health and safety;

·                  emissions to air and discharges to water;

32

Table of Contents

·                  plant and wildlife protection, including endangered species protections;

·                  the reclamation and restoration of properties after mining or other activity has been completed;

·                  remediation of contaminated soil, surface and groundwater; and

·                  the effects of operations on surface water and groundwater quality and availability.

Furthermore, we must compensate employees for work-related injuries through our workers’ compensation insurance funds.  The erosion through tort liability of the protections we are currently provided by workers’ compensation laws could increase our liability for work-related injuries.

MSHA is responsible for monitoring compliance with federal mine health and safety standards at our mines.  MSHA has various enforcement tools that it can use, including the issuance of citations resulting in monetary penalties and orders of withdrawal from a mine or part of a mine.  Since the April 2010 explosion at Massey Energy Company’s (previously acquired by Alpha Natural Resources) Upper Big Branch Mine, increased scrutiny has been placed on the mining industry and has had significant impacts on the regulation of mine safety matters at the federal and state levels.  For example, federal authorities have announced additional targeted inspections of coal mines to evaluate several safety concerns, including the accumulation of coal dust and the proper ventilation of gases such as methane.  Federal authorities are also frequently proposing changes to mine safety rules and regulations, which could potentially result in additional or enhanced required safety equipment, more frequent mine inspections, stricter and more thorough enforcement practices and enhanced reporting requirements.  Any new environmental and/or health and safety requirements may be replicated in the states in which we operate and could increase our operating costs or otherwise prevent, delay or reduce our planned production, any of which could adversely affect our financial condition, results of operations and cash flows.

The costs, liabilities and requirements associated with complying with these requirements are often significant and time-consuming and may delay commencement or continuation of exploration or production.  These factors could have a material adverse effect on our results of operations, cash flows and financial condition.  New legislation or administrative regulations or new judicial interpretations or administrative enforcement of existing laws and regulations may also require us to change operations significantly or incur increased costs.  For example, in November 2011, several environmental groups sued the EPA in Washington federal court to compel the EPA to include coal mines on the list of stationary sources governed by air pollution performance standards.  In that case, the Court denied the groups’ rulemaking petition, and in July 2014, also denied a petition seeking a rehearing of the case en banc.  Any imposition of air emission standards on coal mines or any other such changes could have a material adverse effect on our financial condition and results of operations.

Because of the extensive regulatory environment in which we operate, we cannot assure complete compliance with all laws and regulations.  Failure to comply with these laws may result in significant costs to us to correct such violations, as well as civil or criminal penalties and limitations or shutdowns of our operations.  These laws and regulations may also significantly impair our ability to conduct our mining operations or result in increased operating costs.

Federal and state regulatory agencies have the authority to order any of our mines to be temporarily or permanently closed under certain circumstances, which could materially adversely affect our ability to meet our customers’ demands.

Federal and state regulatory agencies have the authority following significant health and safety incidents, such as fatalities, to order a mine to be temporarily or permanently closed.  If this were to occur, we may be required to incur capital expenditures to re-open the mine.  In the event that these agencies order the closing of our mines, our coal sales agreements and our take-or-pay contracts related to our export terminals may permit us to issue force majeure notices, which suspend our obligations to deliver coal under these contracts.  However, our customers may challenge our issuances of force majeure notices.  If these challenges are successful, we may have to purchase coal from third-party sources, if it is available, to fulfill these obligations, incur capital expenditures to re-open the mines and/or negotiate settlements with the customers, which may include price reductions, the reduction of commitments or the extension of time for delivery or terminate customers’ contracts.  Any of these actions could have a material adverse effect on our business and results of operations.

Our operations may affect the environment or cause exposure to hazardous substances, and our properties may have environmental contamination, any of which could result in material liabilities to us.

Our operations use hazardous materials and generate hazardous and non-hazardous wastes.  In addition, many of the locations that we own, lease or operate were used for coal mining and/or involved the generation, use, storage and disposal of

33

Table of Contents

hazardous substances either before or after we were involved with these locations.  We may be subject to claims under federal and state statutes and/or common law doctrines for toxic torts, natural resource damages and other damages, as well as for the investigation and cleanup of soil, surface water, groundwater and other media.  These claims may arise, for example, out of current or former conditions at sites that we own, lease or operate currently, as well as at sites that we or predecessor entities owned, leased or operated in the past, and at contaminated third-party sites at which we have disposed of hazardous substances and waste.  As a matter of law, and despite any contractual indemnity or allocation arrangements or acquisition agreements to the contrary, our liability for these claims may be joint and several, so that we may be held responsible for more than our share of any contamination, or even for the entire share.

We may incur material costs and liabilities resulting from claims for damage to property or natural resources or injury to persons arising from our operations.  If we are pursued for sanctions, costs and liabilities in respect of these matters, our mining operations and, as a result, our profitability could be materially adversely affected.

Significant increases in taxes we pay on the coal we produce at our mine sites or deliver through our logistics business, such as royalties or severance and production taxes, including as a result of governmental audits, legislative, regulatory, or interpretive changes, could materially and adversely affect our profitability.

We pay federal, state and private royalties and federal, state and county severance and production taxes on the coal we sell.  A substantial portion of our royalties, severance, and production taxes are levied as a percentage of gross revenue with the remaining levied on a per ton basis.  For example, we pay production royalties of 12.5% of gross proceeds to the federal government on all coal sold at the mine sites.  We incurred royalties and severance and production taxes totaling $209.2 million, $208.7 million and $277.1 million for the years ended December 31, 2017, 2016 and 2015, respectively.  The calculations used to determine royalty or severance and production tax payments can be complex and subject to interpretation, making it difficult in some cases to estimate such payments.  If royalties or severance and production tax rates were to significantly increase, or if the methodology by which the government agencies assess royalties or severance and production tax rates materially changes, our results of operations could be materially adversely affected.  See Note 17 of Notes to Consolidated Financial Statements in Item 8.  Examples that could materially adversely affect our results include:

·                  the federal government could again seek to significantly alter the method for valuing royalty payments;

·                  a state government could increase severance or production taxes or any other tax applicable to our operations in that state; and

·                  we could be required to make additional payments (including significant related interest and penalties) as a result of pending or future governmental audits, which can date back many years.

Failure to maintain our surety bonds on acceptable terms could affect our ability to secure reclamation and coal lease obligations and materially adversely affect our ability to mine or lease coal.

Federal and state laws require us to secure the performance of certain long-term obligations, such as mine closure costs, reclamation costs, and federal and state workers’ compensation costs, including black lung.  The primary methods we use to meet those obligations are to provide a third-party surety bond or a letter of credit.  As of December 31, 2017, we had outstanding surety bonds with third parties of $422.9 million.  Surety bond issuers and holders may demand additional collateral, unfavorable terms or higher fees.  Recently, there has been heightened regulatory pressure on reclamation bonding and self-bonding in particular.  Our failure to retain, or inability to acquire, surety bonds or letters of credit or to provide a suitable alternative could adversely affect our ability to mine or lease coal, which would materially adversely affect our business and results of operations.  That failure could result from a variety of factors, including lack of availability, higher expense or unfavorable market terms, the exercise by third-party surety bond issuers of their right to refuse to renew the surety bonds and restrictions on availability of collateral for current and future third-party surety bond issuers under the terms of any credit arrangements then in place.  In addition, as a result of increased credit pressures on the coal industry, it is possible that surety bond providers could demand cash collateral as a condition to providing or maintaining surety bonds.  Any such demands, depending on the amount of any cash collateral required, could have a material adverse impact on our liquidity and financial position.  If we are unable to meet cash collateral requirements and cannot otherwise obtain or retain required surety bonds, we may be unable to satisfy legal requirements necessary to conduct our mining operations.

Furthermore, while we have maintained a history of timely payments related to our LBAs, if we are unable to maintain our “good payer” status, we would be required to seek bonding for any remaining payments, which could adversely impact our cash flows and the amount of availability under our Credit Agreement, if such bonds could be obtained at all.

In addition, if federal or state laws are amended to require certain forms of financial assurance other than surety bonds, such as letters of credit, obtaining them, if we could obtain them at all, could have a material negative impact on our liquidity and results of operations.

Our business requires substantial capital expenditures, which we may be unable to provide.

Our business plan and strategy are dependent upon our acquisitions of additional reserves, which require substantial capital expenditures.  We also require capital for, among other purposes:

·                  acquisition of surface rights;

·                  equipment and the development of our mining operations;

·                  capital renovations;

·                  export terminal development projects;

·                  maintenance and expansions of plants and equipment; and

·                  compliance with environmental laws and regulations.

To the extent that cash on hand, cash generated internally and cash available under our Credit Agreement are not sufficient to fund capital requirements, we will require additional debt and/or equity financing.  However, additional debt or equity financing may not be available to us or, if available, may not be available on satisfactory terms.  Additionally, our debt instruments may restrict our ability to obtain such financing.  If we are unable to obtain additional capital, we may not be able to maintain or increase our existing production rates and we could be forced to reduce or delay capital expenditures or change our business strategy, sell assets or restructure or refinance our indebtedness, all of which could have a material adverse effect on our business or financial condition.

If the assumptions underlying our reclamation and mine closure obligations are materially inaccurate, our costs could be significantly greater than anticipated.

SMCRA and counterpart state laws and regulations establish operational, reclamation and closure standards for all aspects of surface mining.  We accrue for the costs of current mine disturbance and final mine closure.  Estimates of our total reclamation and mine-closing liabilities are based upon permit requirements and our experience.  The amounts recorded are dependent upon a number of variables, including the estimated future asset retirement costs, estimated proven reserves, assumptions involving profit margins of third-party contractors, inflation rates, discount rates and assumed credit-adjusted, risk-free rates.  Furthermore, these obligations are unfunded.  If our accruals are insufficient or our liability in a particular year is greater than currently anticipated, our future operating results could be materially adversely affected.

Increases in the cost of raw materials and other industrial supplies, or the inability to obtain a sufficient quantity of those supplies, could increase our operating expenses, disrupt or delay our production and materially adversely affect our profitability.

We use considerable quantities of explosives, petroleum-based fuels, tires, steel and other raw materials, as well as spare parts and other consumables in the mining process.  If the prices of steel, explosives, tires, petroleum products or other materials increase significantly or if the value of the U.S. dollar declines relative to foreign currencies with respect to certain imported supplies or other products, our operating expenses will increase, which could materially adversely impact our profitability.  Additionally, a limited number of suppliers exist for certain supplies, such as explosives and tires, as well as certain mining equipment, and any of our suppliers may divert their products to buyers in other mines or industries or divert their raw materials to produce other products that have a higher profit margin.  Shortages in raw materials used in the manufacturing of supplies and mining equipment, which, in some cases, do not have ready substitutes, or the cancellation of our supply contracts under which we obtain these raw materials and other consumables, could limit our ability to obtain these supplies or equipment.  As a result, we may not be able to acquire adequate replacements for these supplies or equipment on a cost-effective basis or at all, which could also materially increase our operating expenses or halt, disrupt or delay our production.

Furthermore, operating expenses at our mining locations are sensitive to changes in certain variable costs, including diesel fuel prices, which is one of our largest variable costs.  Our results depend on our ability to adequately control our costs, including diesel fuel.  Any increase in the price we pay for diesel fuel will have a negative impact on our results of operations.  See Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Years Ended December 31, 2017, 2016, and 2015 —Cost of Product Sold” and Item 7A “Quantitative and Qualitative Disclosures About Market Risk—Commodity Price Risk.”

Our hedging activities for diesel fuel may prevent us from benefiting from cost price decreases.

Historically, we have entered into, and may in the future enter into, derivative financial instruments to help manage our exposure to market price changes to our diesel fuel costs, which were indexed to the West Texas Intermediate (“WTI”) crude oil price as quoted on the New York Mercantile Exchange.  As such, the nature of the derivative financial instruments did not directly offset market changes to our diesel fuel costs.

While any future hedge would provide us protection in the event of crude oil price increases, it would reduce our benefit when crude oil prices decrease below our floor and may require substantial payments by us to settle our financial instruments.  See Item 7A “Quantitative and Qualitative Disclosures About Market Risk—Commodity Price Risk” and Note 6 of Notes to Consolidated Financial Statements in Item 8.

Our hedging activities for coal sales prices may result in a negative impact from sales price changes.

As part of our logistics business, we periodically enter into derivative financial instruments in the form of international coal forward contracts to help manage our exposure to future coal sales prices by fixing a price now for a future contracted coal delivery.  This type of hedge is designed to protect us from any price decreases.  While our hedging strategy provides us some degree of protection in the event future coal prices decrease it may also prevent us from benefiting if future coal prices increase above our hedged price and may require substantial payments by us to settle our financial instruments.

In addition, we have periodically used domestic coal futures contracts to help manage our exposure to market changes in domestic coal prices.  This type of hedge is designed to benefit us when prices change relative to our current open positions.  If there are significant and extended unfavorable price movements against our positions, our earnings and liquidity could be negatively impacted.  See Item 7A “Quantitative and Qualitative Disclosures About Market Risk—Commodity Price Risk” and Note 6 of Notes to Consolidated Financial Statements in Item 8.

Changes in the fair value of derivative financial instruments that are not accounted for as a hedge could cause volatility in our earnings.

From time to time, we enter into certain derivative financial instruments to help manage our exposure to future coal prices, both with respect to our export and domestic sales prices and to rises in our diesel costs.  Derivative financial instruments are recognized as either assets or liabilities and are measured at fair value.  To the extent these derivative financial instruments do not qualify for hedge accounting or we choose not to designate them for hedge accounting, we are required to record changes in the fair value of these derivative financial instruments in our Consolidated Statement of Operations, resulting in increased volatility in our income in future periods.

Inaccuracies or future reductions in our estimates of our coal reserves could result in decreased profitability from lower than expected revenue or higher than expected costs.

We base our estimates of reserves on engineering, economic and geological data assembled and analyzed by our internal geologists and engineers, which are reviewed by an independent consultant every two years.  Our estimates of proven and probable coal reserves as to both quantity and quality are updated annually to reflect the production of coal from the reserves, updated geological models and mining recovery data, the tonnage contained in new lease areas acquired and estimated costs of production and sales prices.  There are numerous factors and assumptions inherent in estimating the quantities and qualities of, and costs to mine, coal reserves, any one of which may vary considerably from actual results.  These factors and assumptions include:

·                  coal characteristics such as Btu and sulfur content;

·                  geological and mining conditions, which may not be fully identified by available exploration data and/or may differ from our experiences in areas where we currently mine;

36

Table of Contents

·                  future coal prices and demand;

·                  equipment and productivity;

·                  operating costs, including for critical supplies such as fuel, tires and explosives;

·                  capital expenditures and development and reclamation costs;

·                  the percentage of coal ultimately recoverable;

·                  the effects of regulation, including the issuance of required permits, and taxes, including severance and production taxes and royalties, and other payments to governmental agencies; and

·                  timing for the development of the reserves.

Any changes to the above factors and assumptions could cause our estimates of the quantities and qualities of economically recoverable coal to vary significantly.  Changes to the above factors and assumptions could also materially impact how we classify our reserves based on risk of recovery and our estimates of future net cash flows expected from these properties.  Actual production recovered from identified reserve areas and properties, and revenue and expenditures associated with our mining operations, may vary materially from estimates.  Any inaccuracy or further reductions in our proven and probable reserves estimates could result in decreased profitability from lower than expected revenue and/or higher than expected costs.

The majority of our coal sales agreements are forward sales contracts at fixed prices, which may not reflect favorable then-existing prices for coal or may affect our profitability if we cannot adequately control the costs of production for coal underlying such contracts.

We have historically sold most of our coal under long-term coal sales agreements, which we generally define as contracts with a term of one to five years.  For the year ended December 31, 2017, approximately 87% of our revenue was derived from supply contracts with terms of one year or greater.  The prices for coal sold under these agreements are typically fixed for an agreed amount of time.  Pricing in some of these contracts is subject to certain adjustments in later years or under certain circumstances, and may be below the current market price for similar type coal at any given time, depending on the time frame of the contract.

As a consequence of the substantial volume of our forward sales, our ability to capitalize on near term rises in coal prices is limited.  We have less coal available to sell under short-term contracts or on the spot market and we similarly have fewer tons to commit under long-term contracts at higher prices.  Our ability to realize higher prices is also restricted if customers elect to purchase additional volumes of coal, which is allowable under some contracts, at contract prices that are lower than spot prices.

Furthermore, to the extent our costs increase but pricing under our long-term coal sales agreements remains fixed, we may be unable to pass such increasing costs on to our customers.  If we are unable to control our costs, our results may be negatively impacted.

The loss of, or significant reduction in, purchases by our largest customers could adversely affect our revenue and profitability.

For the year ended December 31, 2017, we derived approximately 21% of our total revenue from sales to our three largest customers and approximately 50% of our total revenue from sales to our ten largest customers.  We may be unsuccessful in obtaining and renewing coal sales agreements with these customers, and some or all of these customers could discontinue purchasing coal from us.  If any of these customers, particularly any of our three largest customers, was to significantly reduce the quantities of coal it purchases from us, or if we are unable to sell coal to these customers on terms as favorable to us, the results of our business would be adversely impacted.

Table of Contents

Changes in purchasing patterns in the coal industry may make it difficult for us to enter into new contracts with customers, or do so on favorable terms, which could materially adversely affect our business and results of operations.

In recent years, we have experienced customers being less willing to enter into long-term coal sales agreements as they continue to adjust to relatively low U.S. natural gas prices, increased price volatility, increased fungibility of coal products, frequently changing regulations that have often disfavored coal usage and the increasing deregulation of their industry.  In addition, the prices for coal in the spot market may be lower than the prices previously set under many of our long-term coal sales agreements.  As our contracts with customers expire or are otherwise renegotiated, our customers may be less willing to extend or enter into new long-term coal sales agreements under their existing or similar pricing terms or our customers may decide to purchase fewer tons of coal than in the past.

To the extent our customers continue to shift away from long-term supply contracts, it will be more difficult to predict our future sales.  As a result, we may not have a market for our future production at acceptable prices.  The prices we receive in the spot market may be less than the contractual price an electric utility is willing to pay for a committed supply.  Furthermore, spot market prices tend to be more volatile than contractual prices, which could result in decreased revenue and profitability.  As of February 2018, we had approximately 45 million tons of committed sales for 2018 and 24 million tons for 2019, which is below our historical forward sales levels, leaving more coal left to be sold for those periods.

As a result of depressed thermal coal demand and competition from low priced natural gas, we received in the past, and may receive in the future, increased requests from customers to renegotiate, defer or cancel committed purchases under existing agreements.  If we are unable to resolve these customer requests on terms that preserve the amount and timing of our forecasted economic value, our anticipated cash flows, results and liquidity may be materially adversely impacted.

From time to time in the ordinary course of our business, customers may seek to renegotiate the terms of our coal sales agreements to reallocate certain committed volumes into future time periods, reduce or cancel committed volumes or make other adjustments to our coal sales agreements. We address these requests on a case-by-case basis and seek to reach mutually agreed resolutions of these requested modifications as part of managing our long-term customer relationships.  As a result of depressed thermal coal demand and competition from low priced natural gas, we have received in the past, and may receive in the future, increased requests from customers to renegotiate, defer or cancel committed purchases under existing agreements, as occurred in early 2016. If we are unable to resolve these customer requests on terms that preserve the amount and timing of our forecasted economic value, our anticipated cash flows, results and liquidity may be materially adversely impacted.

Demand for U.S. thermal coal has declined significantly in recent years and is increasingly subject to fluctuations due to summer cooling demand, winter heating demand, economic growth rates and other factors that impact demand for electricity. This has resulted in a reduction in long-term sales, less visibility into future shipment volumes and increased fluctuations in shipments and associated financial results from period to period.

As a result of regulatory, political, and public pressures against using coal to generate electricity, increased competition with low-cost natural gas, increased competition with taxpayer subsidized solar and wind generation, improving energy efficiency, and other factors, demand for U.S. thermal coal has declined significantly in recent years, supporting a lower percentage of baseload electricity demand, and is increasingly subject to fluctuations due to summer cooling demand, winter heating demand, economic growth rates and other factors that impact demand for electricity.  This has resulted in a reduction in long-term sales of thermal coal, less visibility into future shipment volumes and increased fluctuations in shipments and associated financial results from period to period.  Although we are seeking to adjust our business and cost structure to reflect lower and more variable demand for thermal coal and to address the adverse impact of these changing conditions on our financial performance, our business requires substantial fixed costs and long lead-time investment decisions and we may not be successful in adjusting to these changing conditions.

We are exposed to counterparty risk with our customers, trading partners, financial institutions and other parties with whom we conduct business.

We face an increased risk that we do not receive payment for coal sold and delivered if the creditworthiness of any of our counterparties deteriorates or if any of our counterparties become subject to bankruptcy proceedings.  The creditworthiness of these counterparties depends on any number of factors, including the economic volatility and tightening of credit markets, and deregulation of the U.S. utilities markets, allowing utilities to sell their power plants to their non-regulated affiliates or third parties that may have credit ratings that are below investment grade.  Competition with other coal suppliers could cause us to extend credit to customers and on terms that could increase the risk of payment default.

38

Table of Contents

From time to time, we have contracts to supply coal to energy trading and brokering companies, under which they purchase the coal for their own account or resell to domestic and foreign end users.  If the creditworthiness of these energy trading and brokering companies declines, this would increase the risk that we may not be able to collect payment for all coal sold and delivered to or on behalf of those companies.  Furthermore, if any of these companies seek to renegotiate or cancel sales of coal because of fluctuations in spot prices for coal, issues with their end users accepting the coal or other factors, we may be unable to sell previously anticipated volumes of coal at favorable prices or at all.  We also enter into derivative financial instruments with a number of financial institutions.  If one or more of these institutions were to default on its future obligation to us, our cash flows and results of operations would be negatively impacted.

In certain circumstances we may be entitled to demand credit enhancements or withhold shipments of coal from these parties if we determine they are not creditworthy.  However, these protections may be insufficient to cover our risks or could cause us to resell the coal on the spot market at unfavorable prices or not at all.

We maintain cash balances that we may invest from time to time in marketable securities issued by various counterparties including the U.S. government and U.S. government sponsored entities, municipal entities, financial institutions and other corporations.  If any of these counterparties fail, we could lose the principal invested with such counterparties, which would materially adversely impact our business, liquidity, and results of operations.

Certain provisions in our coal sales agreements may provide limited protection during adverse economic conditions or may result in economic penalties or suspension upon a failure to meet contractual requirements.

Price adjustment, “price re-opener” and other similar provisions in our supply contracts may reduce the protection from short-term coal price volatility traditionally provided by these contracts.  Most of our contracts with mine customers and some of our contracts with logistics customers contain provisions that allow for the base price of our coal to be adjusted due to new statutes, ordinances or regulations that affect our costs related to performance.  Because these provisions only apply to the base price of coal, these terms may provide only limited protection due to changes in regulations.  Some of our contracts with mine customers also contain provisions that allow the purchase prices to be renegotiated at periodic intervals.  A price re-opener provision is one in which either party can renegotiate the price of the contract, sometimes at pre-determined times. Index provisions allow for the adjustment of the price based on a fixed formula.  These provisions may reduce the protection available under our contracts from short-term coal price volatility.  Our international contracts may contain a fixed price for the first year of the contract with future years’ prices to be negotiated at a specific point in time.  If the parties fail to satisfactorily negotiate a price, the contract could be terminated.  Any adjustment or renegotiations leading to a significantly lower contract price, or a termination of the contract, could result in decreased revenue.

Our coal sales agreements with our mine customers typically contain force majeure provisions allowing temporary suspension of performance by us or our customers during the duration of specified events beyond the control of the affected party.  For example, as a result of the very mild 2015/16 winter and low natural gas prices, a greater than normal number of our customers in 2016 sought to reduce the amount of tons delivered to them under our coal sales agreements through contractual remedies, such as contract buyout provisions.  Our contracts with our mine customers also typically allow our customers to suspend performance in the event that the railroad fails to provide its services due to circumstances that would constitute a force majeure.  In addition, our contracts with our international logistics customers generally contain a clause that requires us to pay the demurrage fee charged by the vessel for delays in shipping the coal on behalf of our foreign customers.

Most of our coal sales agreements also contain provisions requiring us to deliver coal within certain ranges for specific coal characteristics, such as heat content, sulfur, ash and ash fusion temperature.  Failure to meet these specifications can result in economic penalties, including price adjustments, suspension, rejection or cancellation of deliveries or termination of the contracts.  A number of our contracts also contain clauses, which, in some cases, may allow customers to terminate the contract in the event of certain changes in environmental laws and regulations.

Our ability to operate our business effectively could be impaired if we fail to attract and retain key personnel.

Our ability to operate our business and implement our strategies depends, in part, on the continued contributions of our executive officers and other key employees.  The loss of any of our key senior executives could have a material adverse effect on our business unless and until we find a qualified replacement.  A limited number of persons exist with the requisite experience and skills to serve in our senior management positions.  We may not be able to locate or employ qualified executives on acceptable terms and our failure to retain or attract qualified executives could have an adverse effect on our ability to operate our business.

Efficient coal mining using modern techniques and equipment also requires skilled laborers in multiple disciplines such as electricians, equipment operators, mechanics, engineers and welders, among others.  We have from time to time encountered shortages for these types of skilled labor and typically compete for such positions with other industries, including oil and gas.  If we experience shortages of skilled labor in the future, our labor and overall productivity or costs could be materially adversely affected.  In the future, we may utilize a greater number of external contractors for portions of our operations.  The costs of these contractors have historically been higher than that of our employed laborers.  If our labor and contractor prices increase, or if we experience materially increased health and benefit costs with respect to our employees, our results of operations could be materially adversely affected.

Our work force could become unionized in the future, which could negatively impact the stability of our production and materially reduce our profitability.

All of our mines are operated by non-union employees.  Our employees have the right at any time under the National Labor Relations Act to form or affiliate with a union, and in the past, unions have conducted limited organizing activities in this regard.  If our employees choose to form or affiliate with a union and the terms of a union collective bargaining agreement are significantly different from our current compensation and job assignment arrangements with our employees, these arrangements could negatively impact the stability of our production and materially reduce our profitability.  In addition, even if our managed operations remain non-union, our business may still be adversely affected by work stoppages at unionized companies or unionized transportation and service providers.

Terrorist attacks and threats, escalation of military activity in response to these attacks or acts of war may materially adversely affect our business and results of operations.

Terrorist attacks and threats, escalation of military activity or acts of war may have significant effects on general economic conditions, fluctuations in consumer confidence and spending, market liquidity, and disruptions to the domestic or international coal supply chains, each of which could negatively impact our business.  Furthermore, any such acts, which directly affect our customers and their business may have negative consequences to our own operations.  Strategic targets such as energy-related assets and transportation assets may be at greater risk of future terrorist attacks than other targets in the U.S. or in other countries.  Disruption or significant increases in energy prices could result in government-imposed price controls.  It is possible that any of these occurrences, or a combination of them, could have a material adverse effect on our business and results of operations, including from delays or losses in transportation, decreased sales of our coal or extended collections from customers that are unable to timely pay us in accordance with the terms of their supply agreement.

We face the risk of systems failures as well as cybersecurity risks, including “hacking.”

The computer systems and network infrastructure we and others use could be vulnerable to unforeseen problems.  These problems may arise in both our internally developed systems and the systems of our third-party service providers.  Our operations are dependent upon our ability to protect computer equipment against damage from fire, power loss or telecommunication failure.  Any damage or failure that causes an interruption in our operations could adversely affect our business.  In addition, our computer systems and network infrastructure present security risks, and could be susceptible to hacking.

Risks Related to Our Indebtedness and Liquidity

Our substantial indebtedness could adversely affect our results of operations and financial condition and prevent us from fulfilling our financial obligations.

As of December 31, 2017, we had consolidated indebtedness of $351.7 million.  We also have lease and royalty obligations related to our federal coal leases.  Our outstanding indebtedness could have important consequences such as:

·                  limiting our ability to obtain additional financing to fund growth, such as mergers and acquisitions; working capital; capital expenditures; debt service requirements; future LBAs; potential cash settlement of equity compensation awards, or other cash requirements;

·                  requiring much of our cash flow to be dedicated to interest obligations and making it unavailable for other purposes;

·                  with respect to any indebtedness under the Credit Agreement or other variable rate debt, exposing us to the risk of increased interest costs if the underlying interest rates rise on our variable rate debt;

40

Table of Contents

·                  limiting our ability to invest operating cash flow in our business (including to obtain new LBAs or make capital expenditures) due to debt service requirements;

·                  causing us to need to sell assets and properties at an inopportune time;

·                  limiting our ability to compete effectively with companies that are not as leveraged and that may be better positioned to withstand economic downturns, including competitors who have become less leveraged when they emerged from bankruptcy;

·                  limiting our ability to acquire new coal reserves and/or LBAs and plant and equipment needed to conduct operations;

·                  limiting our flexibility in planning for, or reacting to, and increasing our vulnerability to, changes in our business, the industry in which we operate and general economic and market conditions; and

·                  a downgrade in the credit rating of our indebtedness, which could increase the cost of further borrowings and negatively impact our available liquidity.

We may incur substantially more debt in the future.  If our indebtedness is further increased, the related risks that we now face, including those described above, could increase.  In addition to the principal repayments on outstanding debt, we have other demands on our cash resources, including significant maintenance and other capital expenditures, including LBAs, and operating expenses.  Our ability to pay our debt depends upon our operating performance.  In particular, economic conditions could cause revenue to decline, and hamper our ability to repay indebtedness.  If we do not have enough cash to satisfy our debt service obligations, we may be required to refinance all or part of our debt, sell assets, limit certain capital expenditures, including future LBAs, or reduce spending or we may be required to issue equity.  We may not be able to, at any given time, refinance our debt or sell assets and we may not be able to, at any given time, issue equity, in either case on acceptable terms or at all.

If we are unable to comply with the covenants or restrictions contained in our debt instruments, the lenders could declare all amounts outstanding under those instruments to be due and payable and foreclose on their collateral, which could materially adversely affect our financial condition and operations.

Our debt instruments include covenants that, among other things, restrict our ability to dispose of assets, incur additional indebtedness, pay dividends or make other restricted payments, create liens on assets, make investments, loans or advances, make acquisitions, engage in mergers or consolidations and engage in certain transactions with affiliates.  The debt instruments also require compliance with various financial covenants.  These restrictions could limit our ability to plan for or react to market conditions or meet extraordinary capital needs or otherwise restrict corporate activities.

A failure to comply with any of these restrictions or covenants could have serious consequences to our financial condition or result in a default under those debt instruments and under other agreements containing cross-default provisions.  A default would permit lenders to accelerate the maturity of the debt under these debt instruments and to foreclose upon collateral securing the debt.  Furthermore, an event of default or an acceleration under one of our debt instruments could also cause a cross-default or cross-acceleration of another debt instrument or contractual obligation, which would adversely impact our liquidity. Under these circumstances, we might not have sufficient funds or other resources to satisfy all of our obligations.  We may not be granted waivers or amendments to these debt instruments if for any reason we are unable to comply with these debt instruments, and we may not be able to refinance our debt on terms acceptable to us, or at all.

Covenants under our Credit Agreement may limit the amount of funds available to us.

Our ability to borrow is subject to the terms and conditions of our Credit Agreement.  The financial covenants are based on a monthly minimum liquidity covenant that requires us to maintain liquidity of not less than $125 million as of the last day of each month.  We had $507.9 million of liquidity under this measure as of December 31, 2017.  Our aggregate available borrowing capacity under the Credit Agreement and the Accounts Receivable Securitization Facility (“A/R Securitization Program”) was approximately $400.0 million as of December 31, 2017.  See Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Credit Agreement” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—A/R Securitization Program.”

Provisions in our debt instruments could discourage an acquisition of us by a third party.

Upon the occurrence of certain transactions constituting a “change of control” as defined in the indentures, holders of the senior notes have the right to require us to repurchase all outstanding notes at 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of repurchase.  Furthermore, a “change in control” as defined in our Credit Agreement is considered an event of default.  These provisions could make it more difficult or more expensive for a third party to acquire us.

Our Credit Agreement provides an important source of our overall liquidity.  We will need to extend or replace the Credit Agreement before its maturity in February 2019.  If we are unable to successfully extend or replace the Credit Agreement in a timely manner, our future financial condition and liquidity may be materially adversely affected.

Our Credit Agreement matures in February 2019.  Our ability to timely extend or replace our Credit Agreement in a sufficient amount, for a sufficient term and on commercially reasonable terms, or at all, may be adversely impacted by numerous other factors, including, our overall financial condition, results and financial projections, the amount and timing of our other obligations and liquidity needs, coal industry conditions in the U.S. and globally, investor sentiment toward the coal industry, the availability of credit and impact of anti-fossil fuel loan and investment restrictions imposed by traditional sources of credit and capital, general debt and capital markets conditions, U.S. and global economic conditions and other factors and circumstances existing at that time.

If we are unable to successfully extend or replace our Credit Agreement in a timely manner in a sufficient amount, for a sufficient term and on commercially reasonable terms, due to any of these or other factors, our future financial condition and liquidity may be materially adversely affected.

Other Risks Related to Our Corporate Structure and Common Stock

Our previous separation from Rio Tinto could subject us and our stockholders to any number of risks and uncertainties.  For example, Rio Tinto has provided notice that it is seeking indemnification under our master separation agreement of any indemnifiable liabilities arising from the climate change litigation in California against Rio Tinto and numerous other fossil fuel industry defendants.

We entered into various agreements with Rio Tinto and its affiliates in connection with the 2009 IPO and separation from Rio Tinto.  CPE Resources agreed to indemnify Rio Tinto for certain liabilities pursuant to these agreements.  As discussed in this Form 10-K in Note 17, “Commitments and Contingencies” of our Consolidated Financial Statements, certain Rio Tinto entities are named defendants in litigation filed in July 2017 by multiple California local governments in California state court, naming numerous fossil fuel companies as defendants (together, the “California Climate Change Litigation”).  The California Climate Change Litigation alleges, among other things, that defendants knowingly contributed to GHG emissions that have adversely impacted the environment, thereby creating financial liabilities for the plaintiffs and that defendants engaged in a coordinated effort to conceal and deny their own knowledge of those climate change threats, discredit scientific evidence and create doubt in the minds of customers, consumers, regulators, the media, journalists, teachers and the public about the consequences of the impacts of their alleged fossil fuel pollution.  Although Cloud Peak Energy is not named as a defendant, in August 2017, Rio Tinto provided Cloud Peak Energy with a notice seeking indemnification pursuant to our 2009 master separation agreement with Rio Tinto, which requires us to indemnify Rio Tinto for certain liabilities relating to our business conducted prior to and after the closing of our 2009 separation from Rio Tinto and may potentially include liabilities in connection with the California Climate Change Litigation.  Because the master separation agreement and other separation-related agreements were entered into while we were part of Rio Tinto, some of the terms of these agreements are likely less favorable to us than similar agreements negotiated between unaffiliated third parties.  Third parties may also seek to hold us responsible for liabilities of Rio Tinto that we did not assume in connection with the 2009 IPO and for which Rio Tinto agreed to indemnify us, including liabilities related to the Jacobs Ranch and Colowyo mines, as well as the uranium mining venture that we do not own.  If any of these liabilities are significant and we are ultimately held liable for them, we may not be able to recover the full amount of our losses from Rio Tinto.  Refer to the applicable exhibits listed in Item 15 of this Form 10-K for the complete terms and conditions of the principal outstanding agreements with Rio Tinto entered into in connection with our 2009 IPO.

The distribution of cash flows by CPE Resources to CPE Inc. is subject to statutory restrictions under the Delaware Limited Liability Company Act and contractual restrictions under CPE Resources’s debt instruments that may limit the ability of CPE Resources to make distributions.  In addition, any distributions and payments of fees or costs are subject to CPE Resources’s financial condition.

As the sole member of CPE Resources, CPE Inc. incurs income taxes on any net taxable income of CPE Resources.  The debt instruments allow CPE Resources to distribute cash in amounts sufficient for CPE Inc. to pay its tax liabilities payable to any governmental entity.  To the extent CPE Inc. needs funds for any other purpose, and CPE Resources is unable to provide such funds for any reason, it could have a material adverse effect on our business, financial condition, results of operations or prospects.

The price of our common stock has declined significantly in the past and could decline further for a variety of reasons, resulting in a substantial loss on investment and negatively impacting our ability to raise equity capital.

Our stock price decreased from $9.26 per share on January 2, 2015 to $2.08 per share on December 31, 2015.  While it has increased to $4.21 per share on February 7, 2018, it could decline again.  Such decline could result from a variety of factors, including, among other things, actual or anticipated fluctuations in our operating results or financial condition, new laws or regulations or new interpretations of existing laws or regulations impacting our business, our customers’ businesses, or the coal transportation and logistics industry, sales of CPE Inc.’s common stock by our stockholders or by us, a downgrade or cessation in coverage from one or more of our analysts, broad market fluctuations and general economic conditions and any other factors described in this “Risk Factors” section of this Form 10-K.

The current trading price of our common stock, or any further decline thereof, might impede our ability to raise capital through the issuance of additional shares of CPE Inc.’s common stock or other equity securities and may cause a loss of  part or all of an investment in shares of our common stock.  In addition, if we sell additional shares of CPE Inc. common stock, that would result in dilution to existing stockholders and may result in decreases to our stock price and the value of existing investments in our stock.  Those decreases may be more significant if we sell additional shares at depressed trading prices.

The closing market price of our common stock has declined significantly in the past.  If the average closing price of our common stock declines to less than $1.00 over 30 consecutive trading days, our common stock could be delisted from the NYSE or trading could be suspended.

Our common stock is currently listed on the NYSE. In order for our common stock to continue to be listed on the NYSE, we are required to comply with various listing standards, including the maintenance of a minimum average closing price of at least $1.00 per share during a consecutive 30 trading-day period. A renewed or continued decline in the closing price of our common stock on the NYSE could result in a breach of these requirements. Although we would have an opportunity to take action to cure such a breach, if we did not succeed, the NYSE could commence suspension or delisting procedures in respect of our common stock. The commencement of suspension or delisting procedures by an exchange remains, at all times, at the discretion of such exchange and would be publicly announced by the exchange. If a suspension or delisting were to occur, there would be significantly less liquidity in the suspended or delisted securities. In addition, our ability to raise additional necessary capital through equity or debt financing, and attract and retain personnel by means of equity compensation, would be greatly impaired. Furthermore, with respect to any suspended or delisted securities, we would expect decreases in institutional and other investor demand, analyst coverage, market making activity and information available concerning trading prices and volume, and fewer broker-dealers would be willing to execute trades with respect to such securities. A suspension or delisting would likely decrease the attractiveness of our common stock to investors and cause the trading volume of our common stock to decline, which could result in a further decline in the market price of our common stock.

We may issue shares of preferred stock with greater rights than our common stock.

Our certificate of incorporation authorizes our Board of Directors to issue one or more series of preferred stock and set the terms of the preferred stock without seeking any further approval from our stockholders. Any preferred stock that is

issued may rank ahead of our common stock in terms of dividends, liquidation rights, or voting rights. If we issue preferred stock, it may adversely affect the market price of our common stock.

We do not expect to pay dividends on our common stock.

We do not expect to pay any dividends on our common stock, in cash or otherwise, in the foreseeable future.  We intend to retain any earnings for use in our business. In addition, the indentures governing our senior notes restrict our ability to pay dividends on our common stock. In the future, we may agree to further restrictions on our ability to pay dividends.

Anti-takeover provisions in our charter documents and other aspects of our structure may discourage, delay or prevent a change in control of our company and may adversely affect the trading price of CPE Inc.’s common stock.

Certain provisions in CPE Inc.’s amended and restated certificate of incorporation and amended and restated bylaws and other aspects of our structure may discourage, delay or prevent a change in our management or a change in control over us that stockholders may consider favorable.  Among other things, CPE Inc.’s amended and restated certificate of incorporation and amended and restated bylaws:

·                  provide for a classified Board of Directors, which may delay the ability of our stockholders to change the membership of a majority of our Board of Directors;

·                  authorize the issuance of “blank check” preferred stock that could be issued by our Board of Directors to thwart a takeover attempt;

·                  do not provide for cumulative voting;

·                  provide that vacancies on the Board of Directors, including newly created directorships, may be filled only by a majority vote of directors then in office;

·                  limit the calling of special meetings of stockholders;

·                  provide that stockholders may not act by written consent;

·                  provide that our directors may be removed only for cause;

·                  require supermajority voting to effect certain amendments to our certificate of incorporation and our bylaws; and

·                  require stockholders to provide advance notice of new business proposals and director nominations under specific procedures.

Coal Reserves

As of December 31, 2017, we controlled approximately 1.0 billion tons of proven and probable coal reserves.  All of our proven and probable reserves are classified as thermal coal.

Table of Contents

The following table summarizes the tonnage of our coal reserves that is classified as proven or probable, and assigned, as well as our property interest, as of December 31, 2017:

(1)                                 Totals reflect rounding.

The following table provides the “quality” (average sulfur content and average Btu per pound) of our coal reserves as of December 31, 2017:

(1)                                 Average Btu per pound includes weight of moisture in the coal on an as-sold basis.

(2)                                 Totals reflect rounding.

We also control certain coal deposits that are contiguous to or near our primary reserve bases.  The tons in these deposits are classified as non-reserve coal deposits and are not included in our reported reserves.  These non-reserve coal deposits include:

·                        7.9 million tons near our Antelope Mine;

·                        53.2 million tons near our Cordero Rojo Mine;

·                        3.9 million tons near our Spring Creek Mine; and

·                        283.6 million tons at the Youngs Creek project.

Non-reserve coal deposits are not reserves under SEC Industry Guide 7.  Estimates of non-reserve coal deposits are subject to further exploration and development, are more speculative and may or may not be converted to future reserves of the company.

Our reserve and non-reserve coal deposit estimates as of December 31, 2017 were prepared by our staff of geologists and engineers, who have extensive experience in PRB coal.  These individuals are responsible for collecting and analyzing geologic data within and adjacent to leases controlled by us.  Our Manager, Geology is the technical person primarily responsible for the preparation of our reserves estimates.  He has a Bachelor of Science degree in Geology and over 10 years of industry experience with positions of increasing responsibility in mining geology and reserve determination.  He reports to our Director, Geological Services and Special Projects, who has a Bachelor of Science degree in Mining Engineering and over 30 years of industry experience with positions of increasing responsibility in coal quality and mine planning, operations, project evaluations, risk management, and technical management at CPE Inc.  The Director, Geological Services and Special Projects reports directly to our Senior Vice President, Technical Services.  An external review of our reserves and non-reserve coal deposit estimates is performed every two years.  The most recent review was performed for the year ended December 31, 2016 and was completed in January 2017 by John T. Boyd Company, mining and geological consultants.  The results verified our reserve and non-reserve coal deposit estimates for the year ended December 31, 2016.

45

Table of Contents

Our coal reserve estimates are based on data obtained from our drilling activities and other available geologic data.  All of our reserves are assigned, associated with our active coal properties, and incorporated in detailed mine plans.  Estimates of our reserves are based on more than 7,000 drill holes.  Our proven reserves have a typical drill hole spacing of 1,500 feet or less, and our probable reserves have a typical drill hole spacing of 2,500 feet or less.

Along with the geological data we assemble for our coal reserve estimates, our staff of geologists and engineers also analyzes the economic data such as cost of production, projected sales price and other data concerning permitting and advances in mining technology.  Various factors and assumptions are utilized in estimating coal reserves, including assumptions concerning future coal prices and operating costs.  These estimates are periodically updated to reflect past coal production and other geologic or mining data.  Acquisitions or sales of coal properties will also change these estimates.  Changes in mining methods or the utilization of new technologies may increase or decrease the recovery basis for a coal seam.

Reserve Acquisition Process

Since our inception, we have focused on growth through the acquisition of proven and probable coal reserves and non-reserve coal deposits.  Historically, this was accomplished through the federal competitive leasing process, known as the LBA process.  For example, in 2011 we acquired 383 million tons of proven and probable coal reserves in two federal coal leases for our Antelope Mine.

We acquire a large portion of our coal through the LBA process, and as a result, most of our coal is held under federal leases.  Under this process, before a mining company can obtain a new federal coal lease, the company must nominate a coal tract for lease and then win the lease through a competitive bidding process.  The LBA process has lasted anywhere from two to five years or more from the time the coal tract is nominated to the time a final bid is accepted by the BLM.  After the LBA is awarded, the company then conducts the necessary testing to determine what amount can be classified as reserves and begins the process to permit the coal for mining, which generally takes another two to five years.  Third-party legal challenges, such as legal challenges filed against the BLM and the Secretary of the Interior by environmental groups with respect to the LBA process in the PRB may result in delays and other adverse impacts on the LBA process.

To initiate the LBA process, companies wanting to acquire additional coal must file an application with the BLM’s state office indicating interest in a specific coal tract.  The BLM reviews the initial application to determine whether the application conforms to existing land-use plans for that particular tract of land and whether the application would provide for maximum coal recovery.  The application is further reviewed by a regional coal team at a public meeting.  Based on a review of the available information and public comment, the regional coal team will make a recommendation to the BLM whether to continue, modify or reject the application.

If the BLM determines to continue the application, the company that submitted the application will pay for a BLM-directed environmental analysis or an EIS to be completed.  This analysis or impact statement is subject to publication and public comment.  The BLM may consult with other government agencies during this process, including state and federal agencies, surface management agencies, Native American tribes or bands, the U.S. Department of Justice or others as needed.  The public comment period for an analysis or impact statement typically occurs over a 60-day period.

After the environmental analysis or EIS has been issued and a recommendation has been published that supports the lease sale of the LBA tract, the BLM schedules a public competitive lease sale.  The BLM prepares an internal estimate of the fair market value of the coal that is based on its economic analysis and comparable sales analysis.  Prior to the lease sale, companies interested in acquiring the lease must send sealed bids to the BLM.  The bid amounts for the lease are payable in five annual installments, with the first 20% installment due when the mining operator submits its initial bid for an LBA.  Before the lease is approved by the BLM, the company must first furnish to the BLM an initial rental payment for the first year of rent along with either a bond for the next 20% annual installment payment for the bid amount, or an application for history of timely payment, in which case the BLM may waive the bond requirement if the company successfully meets all the qualifications of a timely payer.  The bids are opened at the lease sale.  If the BLM decides to grant a lease, the lease is awarded to the company that submitted the highest total bid meeting or exceeding the BLM’s fair market value estimate, which is not published.  The BLM, however, is not required to grant a lease even if it determines that a bid meeting or exceeding the fair market value of the coal has been submitted.  The winning bidder must also submit a report setting forth the nature and extent of its coal holdings to the U.S. Department of Justice for a 30-day antitrust review of the lease.  If the successful bidder was not the initial applicant, the BLM will refund the initial applicant certain fees it paid in connection with the application process, for example the fees associated with the environmental analysis or EIS, and the winning bidder will bear those costs.  Coal awarded through the LBA process and subject to federal leases is administered by the U.S. Department of the Interior under the Federal Coal Leasing Amendment Act of 1976.  Once the BLM has issued a lease, the

46

Table of Contents

company must next complete the permitting process before it can mine the coal.  See Item 1 “Business—Environmental and Other Regulatory Matters—Mining Permits and Approvals.”

The federal coal leasing process is designed to be a public process, giving stakeholders and other interested parties opportunities to comment on the BLM’s proposed and final actions and allow third-party comments.  Because of this, third parties, including NGOs, can challenge the BLM’s actions, which may delay the leasing process.  If these challenges prove successful or are litigated for a prolonged period of time, a coal company’s ability to bid on or acquire a new coal lease could be significantly delayed, or could cause the BLM to not offer a lease for bid at all.  In addition, these types of challenges create some uncertainty with respect to the timing of future LBA bids and lease acquisitions and may ultimately delay the leasing process or prevent mining operations.  Even after a lease has been issued and a successful bidder has paid installment money to the BLM, legal challenges may still seek to delay or prevent mining operations.  It is possible that subsequent EISs for other mines in the PRB currently underway but not yet final could be similarly challenged.  There also exists the possibility of similar challenges to the permitting and licensing process, which is also a public process designed to allow public comments.  The BLM also allows for small tracts of coal to be acquired through the LBM leasing process.  An LBM is a non-competitive leasing process and is used in circumstances where a lessee is seeking to modify an existing federal coal lease by adding less than 960 acres in a configuration that is deemed non-competitive to other coal operators.  For example, in December 2012, we applied for two separate LBMs with the BLM:  one at the Spring Creek Mine and one at the Antelope Mine.  A Decision Record to issue the Antelope LBM was made by the BLM and was appealed by certain environmental groups.  In early 2018, we received re-approval for the Antelope LBM.  In February 2018, the BLM’s re-approval was challenged by three environmental groups.  See Note 17 of Notes to Consolidated Financial Statements in Item 8 for further information.  The Spring Creek application is being processed by the BLM.

Each of our federal coal leases has an initial term of 20 years, renewable for subsequent 10-year periods and for so long thereafter as coal is produced in commercial quantities.  The lease requires diligent development within the first 10 years of the lease award with a required coal extraction of 1% of the total coal under the lease by the end of that 10-year period.  At the end of the 10-year development period, the lessee is required to maintain continuous operations, as defined in the applicable leasing regulations.  In certain cases, a lessee may combine contiguous leases into an LMU.  This allows the production of coal from any of the leases within the LMU to be used to meet the continuous operation requirements for the entire LMU.  We currently have an LMU for our Antelope Mine.  We pay to the federal government an annual rent of $3.00 per acre and production royalties of 12.5% of gross revenue on surface mined coal.  The federal government remits approximately 50% of the production royalty payments to the state after deducting administrative expenses.  Some of our mines are also subject to coal leases with the states of Montana or Wyoming, as applicable, and have different terms and conditions that we must adhere to in a similar way to our federal leases.  Under these federal and state leases, if the leased coal is not diligently developed during the initial 10-year development period or if certain other terms of the leases are not complied with, including the requirement to produce a minimum quantity of coal or pay a minimum production royalty, if applicable, the BLM or the applicable state regulatory agency can terminate the lease prior to the expiration of its term.

Most of the coal we lease from the U.S. comes from “split estate” lands in which one party, such as the federal government, owns the coal and a private party owns the surface.  In order to mine the coal we acquire, we must acquire rights to mine from certain owners of the surface lands overlying the coal.  Certain federal regulations provide a specific class of surface owners, QSOs, with the ability to prohibit the BLM from leasing its coal.  For example, in connection with an LBA tract that we previously nominated for our Cordero Rojo Mine, the BLM indicated that certain surface owners satisfied the regulatory definition of QSO.  If the land overlying a coal tract is owned by a QSO, federal laws prohibit us from leasing the coal tract without first securing surface rights to the land, or purchasing the surface rights from the QSO, which would allow us to conduct our mining operations.  Furthermore, the state permitting process requires us to demonstrate surface owner consent for split estate lands before the state will issue a permit to mine coal.  This consent is separate from the QSO consent required before leasing federal coal.  This right of QSOs and certain other surface owners allows them to exercise significant influence over negotiations and prices to acquire surface rights and can delay the federal coal lease or permitting processes or ultimately prevent the acquisition of the federal coal lease or permit over that land entirely.  There are QSOs that own land adjacent to or near our existing mines that may be attractive acquisition candidates for us.  Typically, we seek to purchase the land overlying our coal or enter into option agreements granting us an option to purchase the land upon acquiring a federal coal lease.  We own substantially all of the land over our reserves.  We may not own or control the land over our non-reserve coal deposits, which would be required before these non-reserve coal deposits could be classified as reserves and mined.

Most of the coal we have acquired from private third parties is in the form of coal leases obtained through private negotiations with one or more third parties.  These leases generally include, among other terms and conditions, a set term of years with the right to renew the lease for a stated period and royalties to be paid to the lessor as a percentage of the sales price. These leases may require payment of a lease bonus or minimum royalty, payable either at the time of execution of the lease or in periodic installments, and a minimum production of coal from the leased areas in order to hold the leases by active

47

Table of Contents

production.  We believe that the term of years will allow the recoverable reserve to be fully extracted in accordance with our projected mine plan.  Consistent with industry practice, we conduct only limited investigations of title to our coal properties prior to leasing.  Title to properties leased from private third parties is not usually fully verified until we make a commitment to develop a property, which may not occur until we have obtained the necessary permits and completed exploration of the property.

We acquired rights to significant coal deposits when we completed the acquisition of the Youngs Creek project, a non-operating mine in Northeast Wyoming in the Northern PRB, whereby we acquired rights to 283.6 million tons of non-reserve coal deposits along with significant related surface assets.  We also announced in 2013 that we signed an option agreement and a corresponding exploration agreement with the Crow Tribe of Indians for the exploration and potential development of significant coal resources on the Crow Indian Reservation in southeast Montana in the Northern PRB region.  See Item 1, “Business—Development Projects—Youngs Creek Project”.  Subject to market conditions, our industry outlook, and other factors, we intend to continue to seek opportunities to acquire additional coal through the federal leasing process as well as through private transactions with third parties or sovereign nations such as the Crow Tribe of Indians.

Office Space

Our corporate headquarters is located in Gillette, Wyoming, where we own approximately 32,000 square feet of office space.  In addition, we lease approximately 28,000 square feet of office space in Broomfield, Colorado under a lease that expires in February 2021.  As of December 31, 2017, all of our long-lived assets were located in the U.S.  See Note 21 of Notes to Consolidated Financial Statements in Item 8.

Overview

We are one of the largest producers of coal in the United States of America (“U.S.”) and the PRB, based on our 2017 coal sales.  We operate some of the safest mines in the coal industry.  According to the most current MSHA data, we have one of the lowest employee all injury incident rates among the largest U.S. coal producing companies.  We currently operate solely in the PRB, the lowest cost region of the major coal producing regions in the U.S., where we own and operate three surface coal mines: the Antelope Mine, the Cordero Rojo Mine, and the Spring Creek Mine.

Our Antelope Mine and Cordero Rojo Mine are located in Wyoming and our Spring Creek Mine is located in Montana.  Our mines produce subbituminous thermal coal with low sulfur content, and we sell our coal primarily to domestic and foreign electric utilities.  Thermal coal is primarily consumed by electric utilities and industrial consumers as fuel for electricity generation.  In 2017, the coal we produced generated approximately 2% of the electricity produced in the U.S.  As of December 31, 2017, we controlled approximately 1.0 billion tons of proven and probable reserves.  We do not produce any metallurgical coal.  See Item 1. “Business—Mining Operations.”

In addition, we have two development projects, both located in the Northern PRB.  The Youngs Creek project is an undeveloped surface mine project located in Wyoming, seven miles south of our Spring Creek Mine, located in Wyoming, and contiguous with the Wyoming-Montana state line.  The Big Metal project is near the Youngs Creek project located on the Crow Indian Reservation in southeast Montana.  These two projects are described in more detail under Item 1. “Business—Development Projects.”

Our logistics business provides a variety of services designed to facilitate the sale and delivery of coal.  These services include the purchase of coal from third parties or from our owned and operated mines, coordination of the transportation and delivery of purchased coal, negotiation of take-or-pay rail agreements and take-or-pay port agreements and demurrage settlement with vessel operators.  See Item 1. “Business—Transportation and Logistics Services” for further discussion.

The recently enacted tax legislation, commonly referred to as the “Tax Cuts and Jobs Act” (“TCJA”), made significant changes to U.S. tax laws, including (i) the reduction in the federal corporate tax rate, (ii) the elimination of the corporate alternative minimum tax (“AMT”) and the ability to offset regular tax liability or claim refunds for AMT credits carried forward, and (iii) imposing limitations on the deductibility of interest expense.  We have historically been subject to the AMT, under which taxes are imposed at a 20% rate on taxable income, subject to certain adjustments, and we have assumed that we would be subject to the AMT in future periods.  As such, the elimination of the AMT and reduction in the federal corporate tax rate to 21% does not have a material impact on our estimates for cash taxes payable in the next several years.  See Item 7. “Liquidity and Capital Resources—Liquidity” for further discussion.

For a discussion on the impact of new tax laws, see Note 15 of Notes to Consolidated Financial Statements in Item 8.

First Quarter 2017 Equity Offering and 2019 Notes Redemption

On February 28, 2017, we issued 13.5 million shares of common stock through a registered underwritten public offering and received proceeds, net of underwriting discounts and commissions, of $64.7 million. We used the net proceeds from the offering to fund the full redemption of our remaining outstanding 8.50% Senior Notes due 2019 (the “2019 Notes”).

52

Table of Contents

On March 31, 2017, we redeemed the 2019 Notes at a total cost of $64.5 million, reflecting a redemption price of 101.417% of the principal amount of $62.1 million, or $63.0 million, plus accrued and unpaid interest of $1.5 million.

·                  the revenue we receive for our logistics services; and

·                  the costs for logistics services, rail and port charges for coal sales made on a delivered basis, including demurrage and any take-or-pay charges.

The volume of coal that we sell in any given year is driven by global and domestic demand for coal-generated electric power.  Demand for coal-generated electric power may be affected by many factors including weather patterns, natural gas prices, railroad performance, the availability of coal-fired and alternative generating capacity and utilization, the closure of coal-fired power plants, environmental and legal challenges, political and regulatory factors, energy policies, international and domestic economic conditions, currency exchange rate fluctuations, and other factors discussed in this Item 7 and in Item 1A “Risk Factors.”

The price at which we sell our coal is a function of the demand for coal relative to the supply.  We typically seek to enter into multi-year contracts with our customers, which helps mitigate the risks associated with any short-term imbalance in supply and demand.  We have historically entered each year with expected production effectively fully sold.  This strategy helped us run our mines at predictable production rates, which improves control of operating costs.  In recent years, our business has become more variable and less predictable because utilities are adjusting their purchasing pattern based on natural gas prices, weather, and other factors and have also been increasingly purchasing coal for shorter terms.

As is common in the PRB, coal seams at our existing mines naturally deepen, resulting in additional overburden to be removed at additional cost.  We have experienced increased operating costs for longer haul distances, maintenance and supplies, and employee wages and salaries.  We have previously used derivative financial instruments to help manage our exposure to diesel fuel prices.  We entered into West Texas Intermediate (“WTI”) derivative financial instruments to hedge our diesel fuel costs in 2017 and 2016.  Historically, we have used WTI derivative financial instruments to manage certain exposures to diesel fuel prices. While currently we have no WTI derivative financial instruments in place, we expect to monitor the derivatives market and may use such derivatives in the future.

We incur significant capital expenditures to maintain, update and expand our mining equipment, surface land holdings and coal reserves.  As the costs of acquiring federal coal leases and associated surface rights increase, our depletion costs also increase.

The volume of coal sold on a delivered basis is influenced by international and domestic market conditions.  Coal sold on a delivered basis to customer-contracted destinations, including sales to Asian customers, involves us arranging and paying for logistics services, which can include rail, rail car hire, vessel chartering, and port charges, including any demurrage incurred and other costs.  These logistics costs are affected by volume, various scheduling considerations, and negotiated rates for rail and port services.  We have exposure to take-or-pay commitments for our rail and port committed capacities.

Current Considerations

Owned and Operated Mines Segment

Mine shipments to domestic customers were 53.1 million tons in 2017 as compared to 57.5 million tons in 2016.  During 2017, shipments in the second half of the year were similar to shipments in the first half, in contrast to historical trends whereby shipments in the second half of the year were higher than the first half.  Natural gas prices averaged approximately $3.00 per MMBtu during the year, as supply stabilized and a ramp-up of liquefied natural gas exports increased demand.  As of December 29, 2017, EIA data showed that natural gas inventories have declined by about 6%, compared to December 2016 levels.  Energy Ventures Analysis estimates there were 75 million tons of PRB coal inventories at utilities at the end of December 2017, a decline of 9 million tons from December 2016 levels.   With the colder weather at the start of 2018, customers continued to reduce stockpiles and we believe they will continue to layer in purchases during 2018 for in-year delivery.  Weather and natural gas prices remain key drivers to our results.

Logistics and Related Activities Segment

International thermal coal prices gained strength during the year due to import demand growth led by China, South Korea, and other Southeast Asian countries.  China has led the growth in imports of thermal coal, increasing its imports in 2017 by 18 million tonnes, or 11%, compared to 2016.  Chinese domestic production continued to rebound with an increase of approximately 146 million tonnes, or 4%, in 2017.  China’s strong domestic production and imports were driven by an increase in electric generation of nearly 7% in 2017, which was mostly supplied by coal-fired generation.  Recent cold weather in China appears to be strengthening import demand.  In South Korea, the commissioning of several new coal-fired units in 2016 and 2017 increased imports of thermal coal by approximately 16 million tonnes, or 17%, in 2017 compared to 2016.

2018 Outlook

We are currently anticipating slightly lower production in 2018 compared to what we experienced over the last two years, primarily due to weak demand for 8400 Btu coal, partially offset by higher export shipments.  We expect domestic coal prices and production levels to remain at or near current levels and then to begin improving as the oversupply of PRB coal diminishes.  Historically, our core cash mining costs, excluding royalties, production taxes, and fuel, have increased as a result of increasing strip ratios and haul distances.  Strip ratios increase as coal seams naturally deepen and require additional overburden removal, which is common in the PRB.  Haul distances increase as mining pits progress further from the load-out.  For 2018, our mine plans indicate that the strip ratio will increase more than recent years resulting in higher costs.  These anticipated higher costs and lower volumes will reduce the contribution from the Owned and Operated Mines segment in 2018.

We exported 1.1 million tons during the fourth quarter 2017 and finished 2017 with 4.2 million tons of exports.  Pricing remains favorable, and we expect export shipments of 5.5 million tons in 2018.  We have sold over 2.5 million tons for delivery in the first half of 2018.  The higher expected export volumes and pricing are anticipated to partially offset the lower expected contribution from the Owned and Operated Mines segment.

Lower domestic coal prices and lower production volumes, such as those experienced recently, may not only decrease our revenues and cash flows but also may reduce the amount of coal we can produce economically.  Lower coal prices may result in asset impairment charges on our long-lived assets, including development projects, due to reductions in the future cash flows associated with our Owned and Operated Mines.  If prices and demand should decline, or remain at current levels for an extended period of time, or not improve as expected, we may incur impairment charges with respect to certain of our long-lived assets.  Additional triggering events could include, but are not limited to, an impairment of coal reserves caused by continued declines in coal prices, increasing costs of production or regulatory changes that adversely impact coal-fired electricity generation.  See Item 1A “Risk Factors—Risks Related to Our Business and Industry—We may not recover our investments in our mining, exploration, port access rights, development projects, and other assets, which may require us to recognize impairment charges related to those assets.”

Environmental and Other Regulatory Matters

Federal, state and local authorities regulate the U.S. coal mining industry with respect to various matters, including air quality standards, water pollution, plant and wildlife protection, the discharge of materials into the environment and the effects of mining on surface and groundwater quality and availability.  These laws and regulations have had, and will continue to have, a significant adverse effect on our production costs and our competitive position relative to certain other sources of electricity generation.  Future laws, regulations or orders, including those relating to global climate change, may cause coal to become a less attractive fuel source, thereby reducing coal’s share of the market for fuels and other energy sources used to generate electricity. See Item 1 “Business—Environmental and Other Regulatory Matters.”

In addition, the change in U.S. Presidential Administrations in 2017 has resulted in a number of executive branch initiatives, some of which are discussed below, that seek to unwind the prior Administration’s fossil fuel actions and to promote development of U.S. natural resources and economic growth.  For instance, the current Administration issued Executive Order 13783 on promoting energy independence and economic growth, which, among other things, directed the United States Environmental Protection Agency (“EPA”) to review the Clean Power Plan (“CPP”) rules and also calls for the review of existing regulations that potentially burden the development or use of domestically produced energy resources.  This executive order further directed the Council on Environmental Quality (“CEQ”) to rescind its final guidance discussing how federal agencies should consider the effects of GHG emissions and climate change in their National Environmental Policy Act (“NEPA”) evaluations, which the CEQ did on April 5, 2017.  This guidance could have created additional delays and costs in the NEPA review process or in our operations, or even an inability to obtain necessary federal approvals for our operations, including due to the increased risk of legal challenges from environmental groups seeking additional analysis of climate impacts.  Nevertheless, because of the uncertainty associated with these initiatives and pending or anticipated legal challenges by certain environmental groups, states or others, we cannot predict the ultimate impact of the current Administration’s initiatives on future demand for coal or our financial results.

Clean Power Plan

In August 2015, the EPA issued the CPP rules that established carbon emission standards for power plants, called CO2 emission performance rates.  The EPA expected each state to develop implementation plans for power plants in its state to meet the individual state targets established in the CPP.  The EPA gave states the option to develop compliance plans for annual rate-based reductions (pounds per megawatt hour) or mass-based tonnage limits for CO2.  The EPA also proposed a federal compliance plan to implement the CPP in the event that an approvable state plan was not submitted to the EPA.

Judicial challenges were filed against the CPP.  On February 9, 2016, the U.S. Supreme Court granted a stay of the implementation of the CPP before the United States Court of Appeals for the District of Columbia (“Circuit Court”) issued a final decision.  By its terms, this stay remains in effect throughout the pendency of the appeals process including at the Circuit Court and the Supreme Court if any certiorari petition is granted.  The stay suspends the rule, including the requirement that states submit their initial plans by September 2016.  The Supreme Court’s stay applies only to EPA’s regulations for CO2 emissions from existing power plants and does not affect EPA’s standards for new power plants, which are also subject to judicial challenges.  On the same day when Executive Order 13783 was issued, the EPA filed a motion in the Circuit Court requesting that the Circuit Court hold the case in abeyance while the EPA conducted the review of the CPP.  The Circuit Court granted the motion and ordered the parties to file a supplemental briefing regarding whether to remand the case to the EPA.

On October 10, 2017, EPA Administrator Pruitt announced that the EPA would seek to repeal the CPP in its entirety.  In connection with the proposed repeal, EPA issued an Advance Notice of Proposed Rulemaking (“ANPRM”) in December 2017 regarding emission guidelines to limit GHG emissions from existing electric utility generating units.  The ANPRM seeks comment regarding what the EPA should include in a potential new, existing-source regulation under the Clean Air Act of GHG emissions from electric utility generating units that it may propose.  Any final rule promulgated by the current Administration would be subject to further judicial review.  It is not clear what changes to the pending appeals, if any, will result from the EPA’s decision to seek repeal of the CPP in its entirety including whether the appellate process regarding the CPP will continue.  Were the CPP upheld so that the rule would be implemented in the current form, or if the ANPRM results in a different proposal to control GHG emissions from electric utility generating units, then demand for coal could, depending on the specific requirements of any new regulations, be further decreased, potentially significantly, and adversely impact our business.

Federal Coal Leasing and Royalties

On March 28, 2017, the Secretary of the U.S. Department of the Interior (“DOI”) lifted a moratorium in effect since January 2016 on the issuance of new leases for coal resources on federally-owned lands.  As a result of this action, the BLM is no longer precluded from accepting new applications for thermal coal sales or modifying existing leases subject to certain exceptions.  This action could benefit members of the coal industry, including our company.

On July 1, 2016 the DOI published the final Consolidated Federal Oil & Gas and Federal & Indian Coal Valuation Reform Rule (“2017 Valuation Rule”).  This rule was developed by the ONRR to significantly change the manner in which non-arm’s length sales of natural resources from federal lands are valued for royalty purposes by mandating a net-back calculation from the first third-party sale and introducing an uncertain default rule.  On February 27, 2017, the DOI postponed implementation of the 2017 Valuation Rule pending review of several petitions that had been filed to challenge the rule.

On August 7, 2017, the DOI followed through on its announced intention and issued a final rule to repeal the 2017 Valuation Rule in its entirety.  As previously indicated by DOI, the agency will return to the benchmarks, which have been consistently and successfully utilized by the energy industry since the late 1980’s.  The states of California and New Mexico have filed a legal challenge to the repeal of the 2017 Valuation Rule in a federal district court in California.  Their lawsuit seeks the reinstatement of the 2017 Valuation Rule.  If the court were to restore the 2017 Valuation Rule to legal effect and that ruling were not overturned on further appeal, that outcome could adversely impact export sales for vertically integrated mining and logistics entities such as Cloud Peak Energy Inc. and place vertically integrated entities at a competitive disadvantage to independent coal brokers or exporters of non-federal coal.
