SunCoke Energy, Inc.: Form 10-K for the period ended Dec 31, 2023

Overview

SunCoke Energy, Inc. (“SunCoke Energy,” “SunCoke,” “Company,” “we,” “our” and “us”) is the largest independent producer of high-quality coke in the Americas, as measured by tons of coke produced each year, and has more than 60 years of coke production experience. Coke is produced by heating metallurgical coal in a refractory oven, which releases certain volatile components from the coal, thus transforming the coal into coke. Our coke is primarily used as a principal raw material in the blast furnace steelmaking process as well as in the foundry production of casted iron, and the majority of our sales are derived from blast furnace coke sales made under long-term, take-or-pay agreements. We also sell coke produced utilizing capacity in excess of that reserved for our long-term, take-or-pay agreements to customers in both the export and North American domestic coke markets seeking high-quality product for their blast furnaces. We have designed, developed and built, and we currently own and operate five cokemaking facilities in the United States (“U.S.”) with collective nameplate capacity to produce approximately 4.2 million tons of blast furnace coke per year. Additionally, we designed and currently operate one cokemaking facility in Brazil under licensing and operating agreements on behalf of ArcelorMittal Brasil S.A. (“ArcelorMittal Brazil”), which has approximately 1.7 million tons of annual cokemaking capacity.

We also own and operate a logistics business that provides export and domestic material handling and/or mixing services to steel, coke (including some of our domestic cokemaking facilities), electric utility, coal producing and other manufacturing based customers. Our logistics terminals, which are strategically located to reach Gulf Coast, East Coast, Great Lakes and international ports, have the collective capacity to mix and/or transload more than 40 million tons of product annually and have storage capacity of approximately 3 million tons.

We report our business results through three reportable segments: Domestic Coke, Brazil Coke and Logistics.

Domestic Coke

Our Domestic Coke segment consists of cokemaking facilities and heat recovery operations at our Jewell, Indiana Harbor, Haverhill, Granite City and Middletown plants. Our core business model is predicated on providing steelmakers an alternative to investing capital in their own captive coke production facilities and to serve as the long-term supplier of high quality coke by investing in our facilities with leading technology, as well as safety and environmental performance. Our cokemaking ovens utilize efficient, modern heat recovery technology designed to combust the coal’s volatile components during the cokemaking process and use the hot flue gas to generate steam and electricity for sale through steam generation facilities or cogeneration plants, respectively. This differs from by-product cokemaking, which repurposes the coal’s volatile components for other uses. Steam generated is generally sold to customers pursuant to steam supply and purchase agreements, and electricity generated is generally sold into the regional power market or to customers pursuant to energy sales agreements.

We believe our advanced heat recovery cokemaking process has numerous advantages over by-product cokemaking, including producing higher quality coke, using waste heat to generate derivative energy for resale, and reducing the environmental footprint. The Clean Air Act Amendments of 1990 specifically directed the U.S. Environmental Protection Agency (“EPA”) to evaluate our heat recovery coke oven technology as a basis for establishing Maximum Achievable Control Technology (“MACT”) standards for new cokemaking facilities. In addition, each of the four cokemaking facilities that we have built since 1990 has either met or exceeded the applicable Best Available Control Technology (“BACT”), or Lowest Achievable Emission Rate (“LAER”) standards, as applicable, set forth by the EPA for cokemaking facilities at that time. We have constructed the only greenfield cokemaking facilities in the U.S. in over 30 years and are the only North American coke producer that utilizes heat recovery technology in the cokemaking process.

The following table sets forth information about our cokemaking facilities:

(1) Cokemaking nameplate capacity represents stated capacity for production of blast furnace coke equivalent production. The production of foundry coke tons does not replace blast furnace coke tons on a ton for ton basis, as foundry coke requires longer coking time.

(2) The Middletown coke sales agreement provides for coke sales on a “run of oven” basis, which includes both blast furnace coke and small coke. Middletown nameplate capacity on a “run of oven” basis is 578 thousand tons per year.

(3) Customers under long-term, take-or-pay agreements include Cleveland-Cliffs Steel Holding Corporation and Cleveland-Cliffs Steel LLC, both subsidiaries of Cleveland-Cliffs Inc. and collectively referred to as “Cliffs Steel”, United States Steel Corporation (“U.S. Steel”), and Algoma Steel Inc. (“Algoma Steel”).

(4) Under the long-term, take-or-pay agreement with Cliffs Steel, Jewell and Haverhill I supply a combined 400 thousand tons annually through 2025. Additionally, the long-term, take-or-pay agreement between Haverhill I and Algoma Steel provides for coke supply to shift to Jewell. Non-contracted blast coke produced utilizing capacity in excess of that reserved for our long-term, take-or-pay agreements at Jewell and Haverhill I is generally sold into the foundry, export and North American spot coke markets.

Blast Furnace Coke

Our blast furnace coke sales are primarily made pursuant to long-term, take-or-pay agreements with the customers noted in the table above. These agreements require us to produce the contracted volumes of coke and require our customers to purchase such volumes of coke up to a specified tonnage or pay the contract price for any tonnage they elect not to take. As a result, our ability to produce the contracted coke volume is a key determinant of our profitability. Our domestic capacity is largely consumed by these long-term agreements, which do not have exposure to the fluctuations in domestic spot prices for blast furnace coke.

Our long-term, take-or-pay coke sales agreements contain pass-through provisions for costs we incur in the cokemaking process, including coal and coal procurement costs, subject to meeting contractual coal-to-coke yields, operating and maintenance expenses, costs related to the transportation of coke to our customers, taxes (other than income taxes) and costs associated with changes in regulation. When targeted coal-to-coke yields are achieved, the price of coal is not a significant determining factor in the profitability of these facilities, although it does affect our revenue and cost of sales for these facilities in approximately equal amounts. However, to the extent that the actual coal-to-coke yields are less than the contractual standard, we are responsible for the cost of the excess coal used in the cokemaking process. Conversely, to the extent our actual coal-to-coke yields are higher than the contractual standard, we realize gains. As coal prices increase, the benefits associated with favorable coal-to-coke yields also increase. These features of our long-term, take-or-pay coke sales agreements reduce our exposure to variability in coal price changes and inflationary costs over the remaining terms of these agreements.

Coke prices in our long-term, take-or-pay agreements also include both an operating cost component and a fixed fee component. During 2023, operating costs under four of our coke sales agreements are fixed subject to an annual adjustment based on an inflation index. Under our other three coke sales agreements, operating costs are passed through to the respective customers subject to an annually negotiated budget, in some cases subject to a cap annually adjusted for inflation, and we share any difference in costs from the budgeted amounts with our customers. Accordingly, actual operating costs in excess of caps or budgets can have a significant impact on the profitability of all of our domestic cokemaking facilities. The fixed fee component for each ton of coke sold to the customer is determined at the time the coke sales agreement is signed and is effective for the term of each sales agreement. The fixed fee is intended to provide an adequate return on invested capital and may differ based on investment levels and other considerations. The actual return on invested capital at any facility is based on the fixed fee per ton and favorable or unfavorable performance on pass-through cost items.

We also sell non-contracted blast furnace coke tons into the North American spot coke and export coke markets, utilizing capacity in excess of that reserved for our long-term, take-or-pay agreements. These non-contracted blast coke sales are generally sold on a spot basis at the current market price, and do not contain the same provisions as our long-term, take-or-pay agreements discussed above.

Foundry Coke

While the revenues in our Domestic Coke segment are primarily tied to blast furnace coke sales made under long-term, take-or-pay agreements, we also produce and sell foundry coke out of our Jewell cokemaking facility. Foundry coke is a high-quality type of coke that is used at foundries to melt iron and various metals in cupola furnaces, which is further processed via casting or molding into products used in various industries such as construction, transportation and industrial products. Foundry coke sales are generally made under annual agreements with our customers for an agreed upon price and do not contain take-or-pay volume commitments.

Brazil

Our Brazil segment consists of our cokemaking operations located in Vitória, Brazil, where we operate the ArcelorMittal Brazil cokemaking facility for a Brazilian subsidiary of ArcelorMittal S.A. Revenues from the Brazilian cokemaking facility are derived from licensing and operating fees, which are based upon the level of production required by our customer and full pass-through of the operating costs of the facility.

Logistics

Our Logistics segment consists of Convent Marine Terminal (“CMT”), Kanawha River Terminal (“KRT”) and SunCoke Lake Terminal (“Lake Terminal”). Our terminals act as intermediaries between our customers and end users by providing transloading and mixing services. Materials are transported in numerous ways, including rail, truck, barge or ship. We do not take possession of materials handled but instead derive our revenues by providing handling and/or mixing services to our customers on a per ton basis. CMT is located in Convent, Louisiana, with strategic access to seaborne markets for coal and other industrial materials. The terminal provides loading and unloading services and has direct rail access and the current capability to transload 15 million tons annually with its top of the line ship loader. The facility serves coal mining customers as well as other merchant business, including aggregates (crushed stone), petroleum coke and iron ore. CMT's efficient barge unloading capabilities complement its rail and truck offerings and provide the terminal with the ability to transload and mix a significantly broader variety of materials, including coal, petroleum coke and other materials from barges at its dock. KRT is a leading metallurgical and thermal coal mixing and handling terminal service provider with collective capacity to mix and transload 25 million tons annually through its operations in Ceredo and Belle, West Virginia. Lake Terminal provides coal handling and mixing services to SunCoke's Indiana Harbor cokemaking operations.

Market Discussion and Competition

Cokemaking

The majority of our current production from our cokemaking business is committed under long-term, take-or-pay agreements. As a result, competition mainly affects our ability to obtain new contracts supporting development of additional cokemaking capacity, including foundry coke, re-contracting existing facilities, as well as the sale of non-contracted blast coke tons in the North American spot coke and export coke markets. We direct our marketing efforts principally towards these areas.

The cokemaking market is highly competitive. Competitors include merchant coke producers as well as the cokemaking facilities owned and operated by blast furnace steel companies. The principal competitive factors affecting our cokemaking business include coke quality and price, reliability of supply, proximity to market, access to metallurgical coals and environmental performance. Most of the world’s coke production capacity is owned by blast furnace steel companies. The international merchant coke market is largely supplied by Chinese and Colombian producers, among others, but it can be challenging to maintain high quality coke in the export market, and when coupled with transportation costs, coke imports into the U.S. are often not economical. However, the supply of coke from international merchants does impact our ability to sell tons in excess of those contracted under out long-term, take-or-pay agreements into the export coke market.

We believe we are well-positioned to compete with other coke producers. In recent years, our Domestic Coke segment has accounted for approximately 37 percent of the U.S. blast furnace coke market capacity. We are the only coke producer who has built new cokemaking facilities in the U.S. in over 30 years, which will allow us to absorb additional market share from aging by-product coke batteries owned by other coke producers. Additionally, our facilities and ovens were constructed using proven, industry-leading technology with many proprietary features allowing us to produce consistently higher quality coke than our competitors produce. Our technology also allows us to produce heat that can be converted into steam or electrical power.

We monitor the development of competing technologies carefully. In recent years, steelmakers have begun to explore alternatives to blast furnace technology that require less or alternatives to coke, such as electric arc furnaces. We also monitor ferrous technologies, such as direct reduced iron production, as these could indirectly impact our blast furnace customers.

During 2023, economic uncertainty, driven by inflation and commodity pricing volatility, resulted in declines in the price of global export coke, reducing the sales price of our non-contracted blast coke. All non-contracted blast coke is produced utilizing capacity in excess of that reserved for long-term, take-or-pay Domestic Coke sales agreements, which largely consume our capacity and are not impacted by the fluctuation of coke prices.

Logistics

Our principal competitors of CMT are located on the U.S. Gulf Coast or U.S. East Coast. CMT is one of the largest export terminals on the U.S. Gulf Coast and provides strategic access to seaborne markets for coal and other bulk materials. Additionally, CMT is the largest bulk material terminal in the lower U.S. with direct rail access on the Canadian National Railway. In 2023, CMT accounted for approximately 42 percent of U.S. thermal coal exports from the U.S. Gulf Coast and approximately 16 percent of total U.S. thermal coal exports. CMT has a state-of-the-art ship loader, the largest of its kind in the world. We believe this ship loader has the fastest loading rate available in the Gulf Region, which should allow our customers to benefit from lower shipping costs. Additionally, CMT has a strategic alliance with a company that performs barge unloading services for the terminal, which provides CMT with the ability to transload and mix a significantly broader variety of materials.

Certain CMT customers are impacted by seaborne export market dynamics. Fluctuations in the benchmark price for coal delivery into northwest Europe, as referenced in the Argus/McCloskey's Coal Price Index Report (“API2 index price”), as well as Newcastle index coal prices, as referenced in the Argus/McCloskey's Coal Price Index (“API6 index price”), which reflect low-ash coal prices shipped from Australia, contribute to our customers' decisions to place tons into the export market and thus impact transloading volumes through CMT. During 2023, decreases in European energy needs, primarily due to mild weather conditions, ample European coal inventory and the stabilization of global thermal coal supply, resulted in lower demand for coal delivery into northwest Europe and negatively impacted export coal volumes from CMT.

Our KRT terminals serve two primary domestic markets, metallurgical coal trade and thermal coal trade. Metallurgical markets are primarily impacted by steel prices and blast furnace operating levels whereas thermal markets are impacted by natural gas prices and electricity demand. Our KRT competitors are generally located within 100 miles of our operations. KRT has fully automated and computer-controlled mixing capabilities that mix coal to within two percent accuracy of customer specifications. KRT also has the ability to provide pad storage and has access to both CSX and Norfolk Southern rail lines as well as the Ohio River system.

Lake Terminal provides coal handling and/or mixing services to our Indiana Harbor cokemaking facility and therefore, does not have any competitors.

Seasonality

Our revenues in our Domestic Coke segment are largely tied to long-term, take-or-pay agreements and as such, are not seasonal. However, our cokemaking profitability is tied to coal-to-coke yields, which improve in drier weather. Accordingly, the coal-to-coke yield component of our profitability tends to be more favorable in the third quarter. Extreme weather may also challenge our operating costs and production in the winter months for our Domestic Coke segment. KRT service demand fluctuates due to changes in the domestic electricity markets. Excessively hot summer weather or cold winter weather may increase commercial and residential needs for air conditioning or heat, which in turn may increase electricity usage and the demand for thermal coal and, therefore, may favorably impact our logistics business. Additionally, operating costs at CMT are impacted by water levels on the Mississippi River, which are often higher in the spring months.

Raw Materials

Metallurgical coal is the principal raw material for our cokemaking operations. All of the metallurgical coal used to produce coke at our domestic cokemaking facilities is purchased from third-parties. We believe there is an adequate supply of metallurgical coal available in the U.S. and worldwide, and we have been able to supply coal to our domestic cokemaking facilities without any significant disruption in coke production.

Each ton of blast furnace coke produced at our facilities requires approximately 1.4 tons of metallurgical coal. We purchased 5.9 million tons of metallurgical coal in 2023. Metallurgical coal is generally purchased on an annual basis via one-year contracts with costs primarily passed through to our customers in accordance with the applicable long-term, take-or-pay coke sales agreements. Occasionally, shortfalls in deliveries by metallurgical coal suppliers require us to procure supplemental coal volumes. As with typical annual purchases, the cost of these supplemental purchases is also generally passed through to our customers. Most metallurgical coal procurement decisions are made through a coal committee structure with customer participation. The customer can generally exercise an overriding vote on most coal procurement decisions. In 2024, our metallurgical coal contracts are generally based on coke production requirements. Refer to our Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A") for further detail on our coal contractual obligations.

Transportation and Freight

For inbound transportation of metallurgical coal purchases, our facilities that access a single rail provider have long-term transportation agreements, and where necessary, coal-mixing agreements that run concurrently with the associated long-term, take-or-pay coke sales agreements for the facility. At facilities with multiple transportation options, including rail and barge, we enter into short-term transportation contracts from year to year. Delivery costs, and annual volume commitments included in certain agreements, are generally passed through to the customers.

For coke sales, the point of delivery varies by agreement and facility. The destination for coke sales under long-term, take-or-pay agreements from our Jewell and Haverhill cokemaking facilities is generally designated by the customer and shipments are made by railcar under long-term transportation agreements, which may include annual volume commitments, and are generally passed through to our customers. The destination for non-contracted blast coke sales is also generally designated by the customer and shipments are made by either railcar, truck, barge or ship. Transportation and freight costs associated with these sales do not contain the same pass through provisions as our long-term, take-or-pay agreements. At our Middletown, Indiana Harbor and Granite City cokemaking facilities, coke is delivered primarily by a conveyor belt leading to the customer’s blast furnace, with the customer responsible for additional transportation costs, if any. Most transportation and freight costs in our Logistics segment are paid by the customer directly to the transportation provider.

Research and Development and Intellectual Property and Proprietary Rights

Our research and development program seeks to improve existing and develop promising new cokemaking technologies, including new product development, and enhance our heat recovery processes. Over the years, this program has produced numerous patents related to our heat recovery coking design and operation, including patents for pollution control systems, oven pushing and charging mechanisms, oven flue gas control mechanisms, high quality foundry coke, higher activity foundry coke, hydrated activated carbon for removing mercury from a flue-gas desulfurization system, corrosion resistant spray dry absorber, low particulate matter quench tower design and various others. Additionally, we have continued to successfully utilize our existing coke ovens to produce foundry coke in addition to our primary product of blast furnace coke. As of December 31, 2023, we had 79 patents issued and 34 pending in the U.S., as well as 250 issued and 80 pending in foreign jurisdictions.

At Vitória, Brazil, where we operate one cokemaking facility on behalf of ArcelorMittal Brazil, we have intellectual property and licensing agreements in place for the entity’s use of our technology. As of December 31, 2023, we had 38 patents issued and 16 pending in Brazil.

Our human capital strategy is focused on workforce composition, talent recruitment and retention, diversity, workforce stability, training and total compensation. At SunCoke we aim to foster an inclusive work environment where our employees are respected, trusted and feel empowered to provide value as individuals and as a collaborative team. We feel our employees offer a fresh perspective on SunCoke operations and so we welcome their ideas on process improvement and value each employee’s contribution across the business. Company leadership and the Compensation Committee of our Board of Directors are actively involved in overseeing the Company’s human capital management programs. The leadership of our Human Resources department, in partnership with local Human Resources and General Managers sponsor the development and oversight of all human capital programs in the organization including: (i) workforce composition, recruitment and retention, (ii) culture, (iii) workforce stability, (iv) employee development and training, (v) benefits, (vi) talent management and total compensation. Additionally, Human Resources works in collaboration with our Legal department, including our Chief Compliance Officer, as necessary for human capital matters, ethics and compliance.

Workforce Culture

Our culture at SunCoke is driven by our core values. SunCoke’s values of excellence, innovation, commitment, integrity and stewardship are at the heart of who we are and how we work every day. They guide our actions and decisions so we can always strive to do the right thing for our stakeholders, our business and each other.

• Excellence: expect the best from yourself, remove obstacles, inspire and support others, embrace diversity and celebrate success.

Workforce Composition and Recruitment

As of December 31, 2023, we have 871 employees in the U.S. Approximately 40 percent of our domestic employees, principally at our cokemaking operations, are represented by the United Steelworkers union under various local collective bargaining agreements. Additionally, approximately 3 percent of our domestic employees are represented by the International Union of Operating Engineers.

As of December 31, 2023, we have 280 employees at the cokemaking facility in Vitória, Brazil, all of whom are represented by a union under a labor agreement.

On recruiting, we partner with reputable recruitment firms to fill key positions. To expand our recruitment pools, we have partnered with a third-party vendor specializing in broader outreach, which presents SunCoke’s open roles to organizations from traditionally underrepresented backgrounds across the nation. This partnership will support our focus on attracting qualified candidates from such backgrounds to apply for positions at SunCoke. In 2023, we required frontline leaders and SunCoke management to attend a diversity and inclusion training. The training was conducted by an outside firm to further develop the ability to create an environment where everyone feels valued and has the opportunity to succeed. While we believe that these efforts are important to the Company’s long-term performance and value, we recognize the importance of pursuing such efforts in legally compliant ways. We are committed to not making employment (including hiring, promotion, and compensation) or other contracting decisions on the basis of any legally protected characteristic.

Workforce Stability & Leadership Experience

Our commitment to employee retention through our talent management, benefits, performance management and total compensation programs is shown through our low regrettable turnover rate of approximately 1 percent in 2023. The stability of our workforce is anchored by our experienced corporate leadership team along with our General Managers that lead the day-to-day operations at our facilities. Our leaders each have an average of nearly 20 years of leadership experience and an average tenure (or length of service) of over 14 years with SunCoke.

Employee Development & Training

SunCoke provides a robust training program that is meant to meet applicable regulatory requirements. In addition to the annual interactive video-based SunCoke Code of Business Conduct and Ethics training we provide to all employees, we also provide specialized trainings on an as-needed basis for current topics throughout the year. Over the past several years, special training topics have included Active Shooter Preparedness, Harassment, Worker’s Compensation, Diversity and Inclusion (Inclusive Leadership, Unconscious Bias at the Workplace), Conducting Effective Investigations, Retirement Planning, and Substance Abuse Awareness.

SunCoke’s Personal Information & Privacy Policy outlines specific procedures for employees to handle sensitive information in a secure and responsible manner. The Personal Information & Privacy Policy is updated periodically to reflect evolving data security best practices. SunCoke utilizes a variety of information security training methods, including training segments on data security best practices and periodic security awareness communications that remind employees to stay vigilant with respect to data security.

We believe in developing our employees both within their daily roles and to be ready for their next assignment at SunCoke. Development occurs in the form of leadership training, cross training, stretch assignments, and on the job training. In 2023, SunCoke signed a contract to partner with a global leadership consulting firm. Frontline supervisors and first-time managers will receive training that we believe is important for their leadership skills development, including training on conflict resolution, high-quality decision making, communication, coaching, and improving safety and workplace performance.

We pride ourselves on being a lean workforce that focuses on developing and promoting talent internally. Our open roles are almost always filled internally, and our key positions (General Manager, Maintenance Manager and Operations Manager) are only filled internally. We engage in succession planning to help identify development and training opportunities for high performing talent, preparing potential successors for our most critical roles through assessment of the incumbents and equipping these employees with individualized development plans and job assignments to help them grow.

Benefits

We offer comprehensive benefits to our employees and their families, including health care coverage, retirement benefits, life and disability insurance, competitive vacation and leave policies. We also offer supplemental benefits programs designed to enhance the daily life and well-being of our employees, including: supplemental life insurance for all eligible family members, supplemental short-term disability, a legal services plan, an identity theft and device protection program, financial retirement planning education and coaching, paid-time off (including time for community service), tuition reimbursement, health management for chronic conditions, a 24/7 employee assistance program, and telemedicine.

Talent Management and Total Compensation

Our full-year performance management process begins with setting annual goals for the Company, which guide the development of functional, local and individual employee goals. Employees and their managers are accountable for the goals and must review their performance against the goals on an ongoing basis. It is our policy to provide employee base wages that are competitive and consistent with employees' positions, skill levels, experience, and geographic location. We use an annual review process to evaluate employees' performance and assist in their development. We believe that individual performance and the results of the Company are directly linked, which is why a significant portion of employee compensation is performance-based. Our short-term incentives include both financial metrics as well as performance-based environmental and safety metrics. The level of pay at risk increases progressively with positions of greater responsibility, with long-term cash and equity incentives with multi-year vesting periods granted at the Director, Vice President and Senior Vice President levels. Further, below the Director level, top performers may be granted long-term cash and equity incentives with multi-year vesting for retention. This helps the Company to retain those identified as having the top skills and abilities that are critical to our business.

Safety

We live by the ethos: Think Safe. Act Safe. Be Safe.

Our top priority has always been the safety and health of our employees, contractors and visitors.

Safety is so important to SunCoke that we include safety in our core values and also incorporate safety as a metric in our short-term incentive program. We have an ambition of zero incidents and injuries in the workplace. To reach our goal, we follow our Safety Vision, which is comprised of five core components including:

• Visible safety leadership - Site and corporate leadership have made a commitment to safety as the paramount value within the Company and our site leadership practices visible safety leadership on a daily basis.
• Communication and training - All team members and contractors take responsibility for their own safety and the safety of those around them, and we train for proper safety knowledge.
• Safe work practices - All team members and contractors take the time necessary to properly identify and mitigate hazards and safely do each job.
• Incident investigation – We have a structured process for investigating incidents and perform root cause analysis of significant incidents.
• Continuous improvement – We are always focused on preventing safety incidents and Thinking Safe, Acting Safe and Being Safe.

Our target for Total Recordable Incident Rate ("TRIR") at SunCoke for 2023 was 0.80 company-wide, which includes both employees and contractors. Our safety performance in 2023 was 0.99 TRIR.

Our excellent safety record is best understood in comparison to industry-wide safety performance. According to the Bureau of Labor Statistics, the TRIR of Other Petroleum and Coal Products (Coke) Manufacturing was 3.1 in 2022 and the TRIR for the Iron and Steel Mills sector was 2.2 in 2022, based on the most recent data available. Our year-over-year safety performance is consistently significantly lower than average industry-wide rates, demonstrating our strong commitment to safety.

Ethics & Compliance

We have adopted a Code of Business Conduct and Ethics that applies to all of our officers, directors and employees, including senior financial officers and executives. Our Code of Business Conduct and Ethics, along with our Core Values, establish the principles that guide our daily actions to uphold the highest standards of ethical and legal behavior. Whether working with customers, vendors, business partners or neighbors, we always strive to act with integrity. All employees must complete annual training on our Code of Business Conduct and Ethics, which we review and update as needed. We educate all employees to avoid potential conflicts of interest. Our Prohibited Payments and Political Contributions Policy addresses payments made to U.S. officials, including campaign contributions. Our Gifts, Entertainment and Sponsored Travel Policy provides guidance regarding business courtesies, including reporting obligations and value limitations. We also have a Human Rights Policy, which affirms our commitment to a fair living wage for all employees.

Guidance & Reporting Without Fear of Retaliation

All employees, officers and directors must report suspected policy violations of our Code of Business Conduct and Ethics to the Compliance Team, which is led by our Chief Compliance Officer and includes representatives from our Human Resources and Legal departments. They can do so through a variety of channels, including, but not limited to, directly reporting to a supervisor, providing email or verbal reports directly to the Compliance Team and using our confidential, third-party 24/7 reporting hotline or website. Calls and online submissions are anonymous, unless the notifying party discloses his or her identity. We take the anonymity of these communications seriously and SunCoke’s Compliance Team follows up on each submission. In addition to the anonymous hotline, hourly employees represented by a collective bargaining unit can also file a report using the applicable union grievance process. Nothing in our Code of Business Conduct and Ethics is intended to prevent anonymous individuals from communicating directly with relevant government authorities about potential violations of law.

Legal and Regulatory Requirements

Our operations are subject to extensive governmental regulation, including environmental laws, which are a significant factor in our business. The following discussion summarizes the principal legal and regulatory requirements that we believe may significantly affect us.

Permitting and Bonding

• Permitting Process for Cokemaking Facilities. The permitting process for our cokemaking facilities is administered by each state individually. However, the main requirements for obtaining environmental construction and operating permits are found in the federal regulations. A construction permit allows construction and commencement of operations at the facility and is generally valid for at least 18 months. Generally, construction commences during this period, while many states allow this period to be extended in certain situations. A facility's operating permit may be a state operating permit or a Title V operating permit.
• Air Quality. Our cokemaking facilities employ MACT standards designed to limit emissions of certain hazardous air pollutants. Specific MACT standards apply to oven door leaks, charging, oven pressure, pushing and quenching. Certain MACT standards for cokemaking facilities were developed using test data from SunCoke's Jewell cokemaking facility located in Vansant, Virginia. Additionally, under applicable federal air quality regulations, permitting requirements may differ among facilities, depending upon whether the cokemaking facility will be located in an “attainment” area—i.e., one that meets the national ambient air quality standards (“NAAQS”) for certain pollutants, or in a “non-attainment” or "unclassifiable" area. The status of an area may change over time as new NAAQS standards are adopted, resulting in an area changing from one status or classification to another. In an attainment area, the facility must install air pollution control equipment or employ BACT. In a non-attainment area, the facility must install air pollution control equipment or employ procedures that meet LAER standards. LAER standards are the most stringent emission limitation achieved in practice by existing facilities. Unlike the BACT analysis, cost is generally not considered as part of a LAER analysis, and emissions in a non-attainment area must be offset by emission reductions obtained from other sources. Any changes in attainment status for areas where our facilities are located present a potential risk that may impact our operations and costs.
• More stringent NAAQS for ambient nitrogen dioxide ("NO2") and sulfur dioxide ("SO2") went into effect in 2010. In July 2013, the EPA identified or "designated" as non-attainment 29 areas in 16 states where monitored air quality showed violations of the 2010 1-hour SO2 NAAQS. In December 2017, the EPA issued a final designation of attainment or unclassifiable for all areas where our facilities are located. These designations mean that no action is required for the facilities with respect to SO2 emissions at this time. However, it is possible for these areas to be redesignated in the future as non-attainment areas. There is a potential risk that any re-designations may have an impact on our operations and costs for facilities located in areas that the EPA determines to be non-attainment with the 1-hour SO2 NAAQS.
• In 2012, more stringent NAAQS for fine particulate matter ("PM"), or PM 2.5, went into effect. In January 2015, the areas where the Granite City and Indiana Harbor facilities are located were designated unclassifiable for PM 2.5, and the areas where the Haverhill and Jewell facilities are located were designated unclassifiable/attainment for PM 2.5. In April 2015, the area where the Middletown facility is located was designated unclassifiable/attainment for PM 2.5. These designations mean that no action is required for the facilities with respect to PM 2.5 emissions at this time. However, on February 7, 2024, the EPA adopted a rule that would lower the annual PM2.5 NAAQS and maintain the daily PM 2.5 standard, the daily PM 10 standard, and the secondary NAAQS for PM 10 and PM 2.5. It is possible that the areas where our facilities are located may be redesignated in the future as non-attainment areas as a result of this rule. If redesignated, there is a potential risk that any re-designations may have an impact on our operations and costs for facilities located in areas that the EPA determines to be non-attainment with the NAAQS.
• In 2015, the EPA revised the existing NAAQS for ground level ozone to make the standard more stringent. In January 2018, the EPA designated the areas where the Haverhill and Jewell facilities are located as attainment/unclassifiable for ozone. In June 2018, the EPA designated the areas where the Granite City, Indiana Harbor, and Middletown facilities are located as marginal nonattainment for ozone. The status of the area where the Indiana Harbor facility is located was challenged in litigation and upheld in July 2020. As a result of the same litigation, the status of the area where the Granite City facility is located was remanded to the EPA, which finalized the area as nonattainment in January 2021. On June 9, 2022, the U.S. the EPA redesignated the area where the Middletown facility is located as an attainment area for the 2015 ozone NAAQS. Nonattainment designations under the new standard and any future more stringent standard for ozone have two potential impacts: (1) demonstrating compliance with the standard using dispersion modeling for permitting new facilities or significant new projects may be more difficult; and (2) facilities operating in areas that are classified as moderate non-attainment areas may be required to install Reasonably Available Control Technology (“RACT”) or demonstrate that they already meet RACT standards. While we are not able to determine the extent to which the 2015 ozone standard will impact our business at this time, it presents a potential risk of having an impact on our operations and costs.
• The EPA adopted a rule in 2010 requiring a new facility that is a major source of greenhouse gases (“GHGs”) to install equipment or employ BACT procedures. Currently, there is little information on what may be acceptable as BACT to control GHGs (primarily carbon dioxide from our facilities), but the database and additional guidance may be enhanced in the future.
• Several states have additional requirements and standards other than those in the federal statutes and regulations. Many states have lists of “air toxics” with emission limitations determined by dispersion modeling. States also often have specific regulations that deal with visible emissions, odors and nuisance. In some cases, the state delegates some or all of these functions to local agencies.
• Wastewater and Stormwater. Our heat recovery cokemaking technology does not discharge process wastewater as is typically associated with by-product cokemaking. Our cokemaking facilities, in some cases, have non-process wastewater and/or stormwater discharge permits.
• Waste. The primary solid waste product from our heat recovery cokemaking technology is calcium sulfate from flue gas desulfurization, which is generally taken to a solid waste landfill. The material from periodic cleaning of heat recovery steam generators has been disposed of off-site as hazardous waste. Our facilities only generate wastes and do not have permits for waste transportation, storage or disposal.
• U.S. Endangered Species Act. The U.S. Endangered Species Act of 1973 and certain counterpart state regulations are intended to protect species whose populations allow for categorization as either endangered or threatened. With respect to permitting additional cokemaking facilities, protection of endangered or threatened species may have the effect of prohibiting, limiting the extent of or placing permitting conditions on soil removal, road building and other activities in areas containing the affected species. Based on the species that have been designated as endangered or threatened on our properties and the current application of these laws and regulations, we do not believe that they are likely to have a material adverse effect on our operations.
• Permitting Requirements for Former Coal Mining Operations. The Surface Mining Control and Reclamation Act of 1977 (“SMCRA”) and applicable state equivalents govern mining permits and reclamation plans, documents defining ownership and agreements pertaining to coal, minerals, oil and gas, water rights, rights of way and surface land and documents required by the Office of Surface Mining Reclamation and Enforcement’s (“OSM’s”) Applicant Violator System.

We currently have no applications pending for new SMCRA permits, but hold several permits for which reclamation is incomplete.

Our reclamation obligations under applicable environmental laws could be substantial. Under accounting principles generally accepted in the U.S. ("GAAP"), we are required to account for the costs related to the closure of mines and the reclamation of the land upon exhaustion of coal reserves. The fair value of an asset retirement obligation is recognized in the period in which it is incurred if a reasonable estimate of fair value can be made. At which time, the present value of the estimated asset retirement costs is capitalized as part of the carrying amount of the long-lived asset. At December 31, 2023, we had an asset retirement obligation of $2.3 million related to estimated mine reclamation costs. The amounts recorded are dependent upon a number of variables, including the estimated future retirement costs, inflation rates, and the assumed credit-adjusted interest rates. Our future operating results would be adversely affected if these accruals were determined to be insufficient. These obligations are unfunded. Failure to comply with the regulatory requirements can result in sanctions.

• Bonding Requirements for Permits Related to Former Coal Mining Operations and Coal Terminals with Surface Mining Permits. Before a SMCRA permit or a surface mining permit is issued, a mine operator must submit a bond or other form of financial security to guarantee the payment and performance of certain long-term mine closure and reclamation obligations. The costs of these bonds or other forms of financial security have fluctuated in recent years and the market terms of surety bonds generally have become less favorable to those entities with legacy mining obligations or terminal operators and others with such permits. These changes in the terms of such bonds have been accompanied, at times, by a decrease in the number of companies willing to issue surety bonds. As of December 31, 2023, we have posted $8.3 million in surety bonds or other forms of financial security for future reclamation.

Regulation of Operations

• Clean Air Act. The Clean Air Act ("CAA") and similar state laws and regulations affect our cokemaking operations. These may be through permitting and/or emissions control requirements relating to criteria

pollutants or MACT standards. These air emissions programs that may affect our operations, directly or indirectly, include, but are not limited to: the Acid Rain Program; NAAQS implementation for SO2, PM, NO2, lead, ozone, and carbon monoxide; GHG rules; the Cross-State Air Pollution Rule; MACT emissions standards for hazardous air pollutants; the Regional Haze Program; New Source Performance Standards (“NSPS”); and New Source Review.

• Regulation of hazardous air pollutants through the development and promulgation of various industry-specific MACT standards impacts our cokemaking facilities. We are subject to two categories of MACT standards. The first category applies to pushing and quenching. The second category applies to emissions from charging and coke oven doors. The EPA is required to make a risk-based determination for pushing and quenching emissions and determine whether additional emissions reductions are necessary. In 2016 and 2022, the EPA issued a request for information and testing to our cokemaking facilities and other companies as part of its residual risk and technology review of the MACT standard for pushing and quenching, and a technology review of the MACT standard for coke ovens and charging emissions. Testing was conducted by our cokemaking facilities in 2017, 2022, and 2023. On August 16, 2023, the EPA proposed a rule that would impose various new emissions limits and other requirements under both categories of MACT standards regulating our cokemaking facilities. We submitted comments for the EPA’s consideration in response to this proposed rule. While we are not able to determine the extent to which any new standards would impact our business at this time, if the rule is finalized as proposed and withstands legal challenges, compliance with some of these proposed requirements may require the installation of additional pollution control systems and presents a potential risk of having an impact on operations and costs at some of our facilities. The EPA is required to finalize any changes to these MACT standards by May 23, 2024 pursuant to a court-ordered deadline.
• The Regional Haze program requires that states submit State Implementation Plans that demonstrate reasonable progress towards achieving natural visibility conditions in Class I areas. On November 5, 2020, the Virginia Department of Environmental Quality (“VDEQ”) requested that the Jewell facility conduct an analysis of potential controls for SO2 under the Regional Haze program. The VDEQ is currently reviewing Jewell’s determination that the installation of new controls is not feasible and any new requirements should be limited to operating pollution controls already present at the facility. Jewell submitted a permit application to the VDEQ related to this determination, which is under review by the VDEQ at this time. While we are not able to determine the extent to which a different determination by the VDEQ or the EPA would impact our business at this time and were it to withstand legal challenges, it presents a potential risk of having an impact on our operations and costs at the Jewell facility.
• On April 6, 2022, the EPA proposed a Federal Implementation Plan Addressing Regional Ozone Transport for the 2015 Ozone NAAQS, which proposed requirements applicable to certain coke plant operations. SunCoke submitted comments on the proposed rule requesting clarification that the rule does not apply to our facilities. In response to comments from SunCoke and other coke manufacturers, the EPA did not regulate coke ovens under the final rule released in March 2023.
• Terminal Operations. Our terminal operations located along waterways and the Gulf of Mexico are also governed by permitting requirements under the CWA (as defined below) and the CAA. These terminals are subject to U.S. Coast Guard regulations and comparable state statutes regarding design, installation, construction, management and security.
• Federal Energy Regulatory Commission. The Federal Energy Regulatory Commission (“FERC”) regulates the sales of electricity from our Haverhill and Middletown facilities, including the implementation of the Federal Power Act (“FPA”) and the Public Utility Regulatory Policies Act of 1978 (“PURPA”). The nature of the operations of the Haverhill and Middletown facilities makes each facility a qualifying facility under PURPA, which exempts the facilities and the Company from certain regulatory burdens, including the Public Utility Holding Company Act of 2005 (“PUHCA”), limited provisions of the FPA, and certain state laws and regulation. The FERC has granted requests for authority to sell electricity from the Haverhill and Middletown facilities at market-based rates and the entities are subject to the FERC’s market-based rate regulations, which require regular regulatory compliance filings.
• Clean Water Act of 1972. The Clean Water Act of 1972 (“CWA”) may affect our operations by requiring water quality standards generally and through the National Pollutant Discharge Elimination System (“NPDES”) program. Regular monitoring, reporting requirements and performance standards are requirements of NPDES

permits that govern the discharge of pollutants into water. Discharges must either meet state water quality standards or be authorized through available regulatory processes such as alternate standards or variances. Additionally, through the CWA Section 401 certification program, states have approval authority over water discharge permits or licenses that might result in a discharge to their waters. Similarly, for permitting or any future water intake and/or discharge projects, our facilities could be subject to the Army Corps of Engineers Section 404 permitting process.

• Resource Conservation and Recovery Act. We may generate wastes, including “solid” wastes and “hazardous” wastes that are subject to the Resource Conservation and Recovery Act (“RCRA”) and comparable state statutes. The EPA has limited the disposal options for certain wastes that are designated as hazardous wastes under the RCRA. Furthermore, it is possible that certain wastes generated by our operations that currently are exempt from regulation as hazardous wastes may in the future be designated as hazardous wastes, and therefore be subject to more rigorous and costly management, disposal and clean-up requirements. Certain of our wastes are also subject to Department of Transportation regulations for shipping of materials. Any changes to hazardous waste standards or the constituents in the wastes generated at our facilities presents a potential risk of having an impact on our operations and cost structure.
• Comprehensive Environmental Response, Compensation, and Liability Act. Under the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”), also known as Superfund, and similar state laws, responsibility for the entire cost of clean-up of a contaminated site, as well as natural resource damages, can be imposed upon current or former site owners or operators, or upon any party who released one or more designated “hazardous substances” at the site, regardless of the lawfulness of the original activities that led to the contamination. In the course of our operations we may have generated and may generate wastes that fall within the CERCLA’s definition of hazardous substances. We also may be an owner or operator of facilities at which hazardous substances have been released by previous owners or operators. Under the CERCLA, we may be responsible for all or part of the costs of cleaning up facilities at which such substances have been released and for natural resource damages. We also must comply with reporting requirements under the Emergency Planning and Community Right-to-Know Act and the Toxic Substances Control Act.
• Pursuant to a court-mandated deadline, the EPA published a final rule in December 2020 that does not impose financial assurance requirements for managing hazardous substances on the coal products manufacturing sector under Section 108(b) of the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (“CERCLA 108(b)”). The EPA’s final rule determined that the risks associated with these facilities’ operations are addressed by existing federal and state programs and regulations and modern industry practices.
• Climate Change Legislation and Regulations. Our facilities are presently subject to the GHG reporting rule, which obligates us to report annual emissions of GHGs. The EPA also finalized a rule in 2010 requiring a new facility that is a major source of GHGs to install equipment or employ BACT procedures. In 2014, the Supreme Court issued a decision holding that although the EPA may not treat GHGs as a pollutant for the purpose of determining whether a source must obtain a PSD or Title V permit, the EPA may continue to require GHG limitations in permits for sources classified as major based on their emission of other pollutants. Currently there is little information as to what may constitute BACT for GHG in most industries. Under this rule, certain modifications to our facilities could subject us to the additional permitting and other obligations related to emissions of GHGs under the New Source Review/Prevention of Significant Deterioration ("NSR/PSD") and Title V programs of the CAA based on whether the facility triggered NSR/PSD because of emissions of another pollutant such as SO2, NOx, PM, ozone or lead.
• The EPA has engaged in various rulemakings in recent years to attempt to regulate GHG emissions from existing and new coal fired power plants. If the EPA were to ever promulgate a similar rule that applies to our facilities, it may present a potential risk of having an impact on our operations and cost structure.
• The SEC has said it intends to finalize new climate rules that, among other matters, may require disclosure of certain climate change-related information. We expect that our operations will be subject to this disclosure rule. However, we cannot predict what such rules may require, the timing of such rules and how significantly they will affect the Company.
• Occupational Safety and Health ACT (OSH Act). Our facilities are subject to regulation by OSHA or MSHA under the OSH Act and other agencies with standards designed to ensure worker safety. These standards impose minimum requirements for our operations to maintain and operate sites and equipment in a safe manner.
• Security. CMT is subject to regulation by the U.S. Coast Guard pursuant to the Maritime Transportation Security Act. We have an internal inspection program designed to monitor and ensure compliance by CMT with these requirements. We believe that we are in material compliance with all applicable laws and regulations regarding the security of the facility.
• Black Lung Benefits Revenue Act of 1977 and Black Lung Benefits Reform Act of 1977, as amended in 1981. Under these laws, U.S. coal mine operators must pay federal black lung benefits and medical expenses to claimants who are current and former employees and last worked for the operator after July 1, 1973. The Patient Protection and Affordable Care Act (“PPACA”), which was implemented in 2010, amended previous legislation and provides for the automatic extension of awarded lifetime benefits to surviving spouses and changes the legal criteria used to assess and award claims. SunCoke is not an active coal mine operator and does not perform or oversee coal mining. However, SunCoke has retained certain black lung liabilities associated with legacy coal operations. Our obligation related to black lung benefits at December 31, 2023 was $58.2 million and was estimated based on various assumptions, including actuarial estimates, discount rates, number of active claims, changes in health care costs and the impact of PPACA.

In addition to the other information included in this Annual Report on Form 10-K and in our other filings with the SEC, the following risk factors should be considered in evaluating our business and future prospects. These risk factors represent what we believe to be the known material risk factors with respect to us and our business. Our business, operating results, cash flows and financial condition are subject to these risks and uncertainties, any of which could cause actual results to vary materially from recent results or from anticipated future results.

These risks are not the only risks we face. Additional risks and uncertainties not currently known to us, or that we currently deem to be immaterial also may materially and adversely affect our business, financial condition, or results of operations.

Risks Inherent in Our Business and Industry

Our cokemaking and logistics businesses are subject to operating risks, some of which are beyond our control. Equipment failures or deterioration of assets, may lead to production curtailments, shutdowns, impairments, or additional expenditures, which could have a material adverse effect on our results of operations and financial condition.

Factors beyond our control could disrupt our cokemaking and logistics operations, adversely affect our ability to service the needs of our customers and increase our operating costs, all of which could have a material and adverse effect on our results of operations. Adverse developments at our cokemaking facilities could significantly disrupt our ability to produce and supply coke, steam, and/or electricity to our customers. Adverse developments at our logistics operations could significantly disrupt our ability to provide handling, mixing, storage, terminalling, transloading and/or transportation services, of coal and other dry and liquid bulk commodities, to our customers. Our operations depend upon critical pieces of equipment that occasionally may be out of service for scheduled upgrades or maintenance or as a result of unanticipated failures. Assets and equipment critical to these operations also may deteriorate or become depleted materially sooner than we currently estimate, resulting in additional maintenance spending or additional replacement capital expenditures.

Our cokemaking and logistics operations are subject to significant hazards and risks, any of which could result in production and transportation difficulties and disruptions, equipment failures and risk of catastrophic loss, permit non-compliance, pollution, personal injury or wrongful death claims and other damage to our properties and the property of others. Such hazards and risks include, but are not limited to:

• geological, hydrologic, or other conditions that may cause damage to infrastructure or personnel;
• fire, explosion, or other major incident causing injury to personnel and/or equipment that causes a cessation, or significant curtailment, of all or part of our cokemaking or logistics operations at a site for a period of time;
• processing and plant equipment failures or malfunction, operating hazards and unexpected maintenance problems affecting our cokemaking or logistics operations, or our customers;
• adverse weather conditions and natural disasters, such as severe winds, heavy rains or snow, flooding, extreme temperatures and other natural events, including those resulting from climate change, affecting our cokemaking or logistics operations, transportation, or our customers; and
• possible legal challenges to the renewal of key permits, which may lead to their renewal on terms that restrict our cokemaking or logistics operations, or impose additional costs on us.

If any of these conditions or events occur, our cokemaking or logistics operations may be disrupted, operating costs could increase significantly and we could incur substantial losses. Such disruptions in our operations could materially and adversely affect our financial condition or results of operations. In particular, to the extent a disruption leads to our failure to maintain the temperature inside our coke oven batteries, we may not be able to maintain the integrity of the ovens or to continue operation of such coke ovens, which could adversely affect our ability to meet our customers’ requirements for coke and, in some cases, electricity and/or steam.

If our assets do not generate the amount of future cash flows that we expect, or we are not able to execute on capital maintenance or procure replacement assets in an economically feasible manner, our future results of operations may be materially and adversely affected.

The financial performance of our cokemaking and logistics businesses is substantially dependent upon a limited number of customers, and the loss of any of these customers, or any failure by them to perform under their contracts with us, could materially and adversely affect our financial condition, permit compliance, results of operations and cash flows.

Substantially all of our coke sales currently are made pursuant to long-term contracts with Cliffs Steel and U.S. Steel. We expect these customers, and/or their respective successors in interest, by operation of merger, or otherwise, to continue to account for a significant portion of our revenues for the foreseeable future.

We are subject to the credit risk of our major customers and other parties. If we fail to adequately assess the creditworthiness of existing or future customers or unanticipated deterioration of their creditworthiness, any resulting increase in nonpayment or nonperformance by them could have a material adverse effect on our cash flows, financial position or results of operations. During periods of weak demand for steel or coal, our customers may experience significant reductions in their operations, or substantial declines in the prices of the steel, or coal products, they sell. These and other factors such as labor relations or bankruptcy filings may lead certain of our customers to seek renegotiation or cancellation of their existing contractual commitments to us, or reduce their utilization of our services.

The loss of any of these customers (or financial difficulties at any of these customers, which result in nonpayment or nonperformance) could have a significant adverse effect on our business. If one or more of these customers were to significantly reduce its purchases of coke or logistics services from us without a make-whole payment, or default on their agreements with us, or terminate or fail to renew their agreements with us, or if we were unable to sell such coke or logistics services to these customers on terms as favorable to us as the terms under our current agreements, our cash flows, financial position, permit compliance, or results of operations could be materially and adversely affected.

Impairment in the carrying value of long-lived assets could adversely affect our business, financial condition and results of operations.

We have a significant amount of long-lived assets on our Consolidated Balance Sheets. Under generally accepted accounting principles, long-lived assets must be reviewed for impairment whenever adverse events or changes in circumstances indicate a possible impairment. We are required to perform impairment tests on our assets whenever events or changes in circumstances lead to a reduction of the estimated useful life or estimated future cash flows that would indicate that the carrying amount may not be recoverable or whenever management’s plans change with respect to those assets. If business conditions or other factors cause profitability and cash flows to decline, we may be required to record non-cash impairment charges.

Events and conditions that could result in impairment in the value of our long-lived assets include: the impact of a downturn in the global economy, competition, advances in technology, adverse changes in the regulatory environment, new contracts and/or modification, termination or non-renewal of existing contracts, and other factors leading to a reduction in expected long-term sales or profitability, or a significant decline in the trading price of our common stock or market capitalization, lower future cash flows, slower industry growth rates and other changes in the industries in which we or our customers operate.

We face competition, both in our cokemaking operations and in our logistics business, which has the potential to reduce demand for our products and services, and that could have an adverse effect on our financial condition and results of operations.

We face competition, both in our cokemaking operations and in our logistics business:

• Cokemaking operations: Historically, coke has been used as a main input in the production of steel in blast furnaces. However, some blast furnace operators have relied upon natural gas, pulverized coal, and/or other coke substitutes. Many steelmakers also are exploring alternatives to blast furnace technology that require less or no use of coke or alternatives that reduce the amount of GHG emissions from the process. For example, electric arc furnace technology is a commercially proven process widely used in the U.S. As these alternative processes for production of steel become more widespread, the demand for blast furnace coke, including the coke we produce, may be significantly reduced. We also face competition from alternative cokemaking technologies, including both by-product and heat recovery technologies. As these technologies improve and as new technologies are developed, competition in the cokemaking industry may intensify. As alternative processes for production of steel become more widespread, the demand for blast furnace coke, including the coke we produce, may be significantly reduced.
• Logistics business: Decreased throughput and utilization of our logistics assets could result indirectly due to competition in the electrical power generation business from abundant and relatively inexpensive supplies of

natural gas displacing thermal coal as a fuel for electrical power generation by utility companies. In addition, competition in the steel industry from processes such as electric arc furnaces, or blast furnace injection of pulverized coal or natural gas, may reduce the demand for metallurgical coals processed through our logistics facilities. In the future, additional coal handling facilities and terminals with rail and/or barge access may be constructed in the Eastern U.S. Such additional facilities could compete directly with us in specific markets now served by our logistics business. Certain coal mining companies and independent terminal operators in some areas may compete directly with our logistics facilities. In some markets, trucks may competitively deliver mined coal to certain shorter-haul destinations, resulting in reduced utilization of existing terminal capacity.

Such competition could reduce demand for our products and services, thus having an adverse effect on our financial condition and results of operations.

We are subject to extensive laws and regulations, which may increase our cost of doing business and have an adverse effect on our cash flows, financial position or results of operations.

Our operations are subject to strict regulation by federal, state and local authorities with respect to: discharges of substances into the surrounding environment including the air, water and ground; emissions of GHGs; compliance with the NAAQS; management and disposal of hazardous substances and wastes; cleanup of contaminated sites; protection of groundwater quality and availability; protection of plants and wildlife; reclamation and restoration of properties after completion of mining or drilling; sales of electric power; installation of safety equipment in our facilities; and protection of employee health and safety. Complying with these and other regulatory requirements, including the terms of our permits, can be costly and time-consuming, and may hinder operations. In addition, these requirements are complex, change frequently and have become more stringent over time. Regulatory requirements, including those related to GHGs, and various CAA programs, may change in the future in a manner that could result in substantially increased capital, operating and compliance costs, which could have an adverse effect on our financial condition and results of operations.

Failure to comply with applicable laws, regulations or permits may result in the assessment of administrative, civil and criminal penalties, the imposition of cleanup and site restoration costs and liens, the issuance of injunctions to limit or cease operations, the suspension or revocation of permits and other enforcement measures that could cause delays in permitting or development of projects or materially limit, or increase the cost of, our operations. We may not have been, or may not be, at all times, in complete compliance with all such requirements, and we may incur material costs or liabilities in connection with such requirements, or in connection with remediation at sites we own, or third-party sites where it has been alleged that we have liability, in excess of the amounts we have accrued. For a description of certain environmental laws and matters applicable to us and associated risks, see “Item 1. Business-Legal and Regulatory Requirements.”

Our operations may impact the environment or cause exposure to hazardous substances, which could result in material liabilities to us.

Our operations result in emissions of various substances to the air, including GHGs, use hazardous materials, and generate solid and hazardous waste. We have in the past and could in the future be subject to claims under federal, state and local laws and regulations arising from these activities, including for the investigation and clean-up of soil, surface water, or groundwater. Some environmental laws also can impose liability regardless of fault or legality at the time in question, including the characterization of materials. We previously have been and could again in the future be subject to litigation for alleged bodily injuries or property damage arising from claimed exposure to emissions or hazardous substances allegedly used, released, or disposed of by us, as well as litigation related to climate change by governments, private entities, or individuals. Although we make every effort to avoid litigation, these matters are not totally within our control. We will contest these matters vigorously and have made insurance claims where appropriate, but because of the uncertain nature of litigation and coverage decisions, we cannot predict the outcome of these matters. Environmental impacts resulting from our operations, including exposures to emissions, hazardous substances, or wastes associated with our operations, could result in costs and liabilities that could adversely impact our financial condition and results of operations.

We may be unable to obtain, maintain or renew permits or leases necessary for our operations, which could materially reduce our production, cash flows or profitability.

Our cokemaking and logistics operations require us to obtain a number of permits that impose strict regulations on various environmental and operational matters. These, as well as our facilities and operations (including our generation of electricity), require permits issued by various federal, state and local agencies and regulatory bodies. The permitting rules, and the interpretations of these rules, are complex, change frequently, and are often subject to discretionary interpretations by our regulators, all of which may make compliance more costly, difficult or impractical, and may possibly preclude the continuance of ongoing operations or the development of future cokemaking and/or logistics facilities. Non-governmental organizations, environmental groups and individuals have certain rights to engage in the permitting process, and may comment upon, or object to, the requested permits. Such persons also have the right to bring citizen’s lawsuits to challenge the issuance of permits, or the validity of environmental impact statements related thereto. If any permits or leases 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 operations, it could have an adverse effect on our financial condition and results of operations.

Our businesses are subject to inherent risks, some for which we maintain third party insurance and some for which we self-insure. We may incur losses and be subject to liability claims that could have a material adverse effect on our financial condition, results of operations or cash flows.

We maintain insurance policies that provide limited coverage for some, but not all, potential risks and liabilities associated with our business. We may not obtain insurance if we believe the cost of available insurance is excessive relative to the risks presented. As a result of market conditions, premiums and deductibles for certain insurance policies can increase substantially, and in some instances, certain insurance may become unavailable or available only for reduced amounts of coverage. As a result, we may not be able to renew our existing insurance policies or procure other desirable insurance on commercially reasonable terms, if at all. In addition, certain risks, such as certain environmental and pollution risks, and certain cybersecurity risks, generally are not fully insurable. We must compensate employees for work-related injuries. If we do not make adequate provision for our workers' compensation liabilities, or we are pursued for applicable sanctions, costs, and liabilities, our operations and our profitability could be adversely affected. Even where insurance coverage applies, insurers may contest their obligations to make payments. Our financial condition, results of operations and cash flows could be materially and adversely affected by losses and liabilities from un-insured or under-insured events, as well as by delays in the payment of insurance proceeds, or the failure by insurers to make payments.

We may not be able to successfully implement our growth strategies or plans, and we may experience significant risks associated with future acquisitions, investments and/or divestitures. If we are unable to execute our strategic plans, whether as a result of unfavorable market conditions in the industries in which our customers operate, or otherwise, our future results of operations could be materially and adversely affected.

A portion of our strategy to grow our business is dependent upon our ability to acquire and operate new assets that result in an increase in our earnings. We may not derive the financial returns we expect on our investment in such additional assets or such operations may not be profitable. We cannot predict the effect that any failed expansion may have on our core businesses. The success of our future acquisitions and/or investments will depend substantially on the accuracy of our analysis concerning such businesses and our ability to complete such acquisitions or investments on favorable terms, as well as to finance such acquisitions or investments and to integrate the acquired operations successfully with existing operations. Risks associated with acquisitions include the diversion of management’s attention from other business concerns, the potential loss of key employees and customers of the acquired business, the possible assumption of unknown liabilities, potential disputes with the sellers, and the inherent risks in entering markets or lines of business in which we have limited or no prior experience. Antitrust and other laws may prevent us from completing acquisitions. If we are not able to execute our strategic plans effectively, or successfully integrate new operations, whether as a result of unfavorable market conditions in the industries in which our customers operate, or otherwise, our business reputation could suffer and future results of operations could be materially and adversely affected.

In the event we form joint ventures or other similar arrangements, we must pay close attention to the organizational formalities and time-consuming procedures for sharing information and making decisions. We may share ownership and management with other parties who may not have the same goals, strategies, priorities, or resources as we do. The benefits from a successful investment in an existing entity or joint venture will be shared among the co-owners, so we will not receive the exclusive benefits from a successful investment. Additionally, if a co-owner changes, our relationship may be materially and adversely affected.

We regularly review strategic opportunities to further our business objectives, and may eliminate assets that do not meet our return-on-investment criteria. The anticipated benefits of divestitures and other strategic transactions may not be realized, or may be realized more slowly than we expected. Such transactions also could result in a number of financial consequences having a material adverse effect on our results of operations and our financial position, including reduced cash balances; higher fixed expenses; the incurrence of debt and contingent liabilities (including indemnification obligations); restructuring charges; loss of customers, suppliers, distributors, licensors or employees; legal, accounting and advisory fees; and impairment charges.

Our operating results have been and may continue to be affected by fluctuations in our costs of production, and, if we cannot pass increases in our costs of production to our customers, our financial condition, results of operations and cash flows may be negatively affected.

Our operations require a reliable supply of equipment, replacement parts and metallurgical coal. If the cost to produce coke and provide logistics services increases due to price or usage, including cost of supplies, equipment, metallurgical coal or labor, and we cannot pass such increases in our costs of production to our customers, our profit margins may be reduced and our financial condition, results of operations and cash flows may be adversely affected.

We may incur costs and liabilities resulting from claims for damages to property or injury to persons arising from our operations, and such costs and liabilities could have a material and adverse effect on our financial condition or results of operations.

Our success depends, in part, on the quality, efficacy and safety of our products and services. If our operations do not meet applicable safety standards, or our products or services are found to be unsafe, our relationships with customers could suffer and we could lose business or become subject to liability or claims. In addition, our cokemaking and logistics operations have inherent safety risks that may give rise to events resulting in death, injury, or property loss to employees, customers, or unaffiliated third parties. Depending upon the nature and severity of such events, we could be exposed to significant financial loss, reputational damage, potential civil or criminal government or other regulatory enforcement actions, or private litigation, the settlement or outcome of which could have a material and adverse effect on our financial condition or results of operations.

A new or more stringent greenhouse gas emission standard designed to address climate change and physical effects attributed to climate change may adversely affect our operations and impose significant costs on our business and our customers and suppliers.

There is increasing regulatory attention concerning the issue of climate change and the impact of GHGs, particularly from fossil fuels, which are integral to our cokemaking and logistics businesses. Our business and operations, as well as the business and operations of our key suppliers and customers, may become subject to legislation or regulation intended to limit GHG emissions or the use of fossil fuels. It is not possible to foresee the details of such legislation or regulations or changes in the economy or their resulting effects on our business. Because our coking process is dependent on coal as a raw material and the coking process generates carbon dioxide, we are limited in our ability to reduce our GHG emissions and could be affected by future regulation of GHGs. Future legislation or regulation regarding climate change and GHG emissions could have a material adverse effect on our financial condition and results of operations.

Climate change may cause changes in weather patterns and increase the frequency or severity of weather events and flooding. An increase in severe weather events and flooding may adversely impact us, our operations, and our ability to procure raw materials and manufacture and transport our products which could have a material adverse effect on our financial condition and results of operations. Extreme weather conditions may increase our costs, temporarily impact our production capabilities or cause damage to our facilities. For example, our terminals are located near bodies of water and may be impacted by flooding or hurricanes, disrupting our or our customers' ability to move products. Our coke plants are also generally located near bodies of water and may be impacted by the effects of climate change. Additionally, extreme cold could prevent coal delivery and unloading at our coke plants, impeding operation, or create a more hazardous outdoor working environment for our employees.

Investor interest in climate change, fossil fuels, and sustainability could adversely affect our business and our stock price.

Climate change and sustainability have increasingly become important topics to investors and the community at large. As such, there have been recent efforts aimed at the investment community to encourage the divestment of shares of companies associated with energy, coal and/or fossil fuels, as well as to pressure lenders and other financial services companies to limit or curtail business relations with coal and fossil fuel companies. If these efforts are successful, our stock price and our ability to access capital markets may be negatively impacted. Members of the investment community are also increasing their focus on sustainability practices, including management of GHGs and climate change. To the extent ESG matters impact our reputation, they may also impact our ability to attract or retain employees or customers. As a result, we may face increasing pressure regarding our sustainability disclosures and practices.

While we have in the past engaged, and expect in the future to continue to engage, in voluntary initiatives (such as voluntary disclosures, certifications, or goals, among others) on “ESG matters”, such as sustainability and inclusion, to respond to stakeholder expectations, such initiatives may be costly and may not have the desired effect. For example, actions or statements that we may take based on expectations, assumptions, or third-party information may at some point be determined to be erroneous or otherwise not in keeping with best practices. If we fail to, or are perceived to fail to, appropriately advance certain initiatives or use appropriate methodologies and data sources, we may be subject to various adverse impacts, including reputational damage, stakeholder engagement, and/or litigation. Simultaneously, there are efforts by some parties, including some policymakers and activists, to constrain or eliminate companies' efforts on various ESG-related matters. To the extent we are subject to any such activism, it may require us to incur costs or otherwise adversely impact our business. Many of our customers, business partners, and suppliers may be subject to similar expectations, which may augment or create additional risks, including risks that may not be known to us.

Risks Related to Our Cokemaking Business

If a substantial portion of our agreements to supply coke, electricity, and/or steam are modified or terminated, our cash flows, financial position, permit compliance, results of operations and/or carrying value of our long-lived assets may be adversely affected if we are not able to replace such agreements, or if we are not able to enter into new agreements at the same level of profitability.

We make substantially all of our coke, electricity and steam sales under long-term agreements. If a substantial portion of these agreements are modified or terminated or if force majeure is exercised, our results of operations may be adversely affected if we are not able to replace such agreements, or if we are not able to enter into new agreements at the same level of profitability. The profitability of our long-term coke, energy and steam sales agreements depends on a variety of factors that vary from agreement to agreement and fluctuate during the agreement term. We may not be able to obtain long-term agreements at favorable prices, compared either to market conditions or to our cost structure. Price changes provided in long-term supply agreements may not reflect actual increases in production costs. As a result, such cost increases may reduce profit margins on our long-term coke and energy sales agreements. In addition, contractual provisions for adjustment or renegotiation of prices and other provisions may increase our exposure to short-term price volatility.

From time to time, we discuss the extension of existing agreements and enter into new long-term agreements for the supply of coke, steam, and energy to our customers, but these negotiations may not be successful and these customers may not continue to purchase coke, steam, or electricity from us under long-term agreements. In addition, declarations of bankruptcy by customers can result in changes in our contracts with less favorable terms. If any one or more of these customers were to become financially distressed and unable to pay us, significantly reduce their purchases of coke, steam, or electricity from us, or if we were unable to sell coke or electricity to them on terms as favorable to us as the terms under our current agreements, our cash flows, financial position, permit compliance or results of operations may be materially and adversely affected.

Further, because of certain technological design constraints, we do not have the ability to shut down our cokemaking operations if we do not have adequate customer demand. If a customer refuses to take or pay for our coke, we must continue to operate our coke ovens even though we may not be able to sell our coke immediately and may incur significant additional costs for natural gas to maintain the temperature inside our coke oven batteries and fees under our rail contracts to account for reductions in inbound coal or outbound coke shipments at our plants, which may have a material and adverse effect on our cash flows, financial position or results of operations.

Excess capacity in the global steel industry, and/or increased exports of coke from producing countries, may weaken our customers' demand for our coke and could materially and adversely affect our future revenues and profitability.

In some countries, steelmaking capacity exceeds demand for steel products. Rather than reducing employment by matching production capacity to consumption, steel manufacturers in these countries (often with local government assistance or subsidies in various forms) may export steel at prices that are significantly below their home market prices and that may not reflect their costs of production or capital. Our steelmaking customers may decrease the prices they charge for steel, or take other action, as the supply of steel increases. The profitability and financial position of our steelmaking customers may be adversely affected, causing such customers to reduce their demand for our coke and making it more likely that they may seek to renegotiate their contracts with us or fail to pay for the coke they are required to take under our contracts. In addition, future increases in exports of coke from China and/or other coke-producing countries also may reduce our customers' demand for coke capacity. Such reduced demand for our coke could adversely affect the certainty of our long-term relationships with our customers, depress coke prices, and limit our ability to enter into new, or renew existing, commercial arrangements with our customers, as well as our ability to sell into the North American spot coke and export coke markets, and could materially and adversely affect our future revenues and profitability.

Certain provisions in our long-term coke agreements may result in economic penalties to us, or may result in termination of our coke sales agreements for failure to meet minimum volume requirements, coal-to-coke yields or other required specifications, and certain provisions in these agreements and our energy sales agreements may permit our customers to suspend performance.

Our agreements for the supply of coke, energy and/or steam, contain provisions requiring us to supply minimum volumes of our products to our customers. To the extent we do not meet these minimum volumes, we are generally required under the terms of our long-term agreements to procure replacement supply to our customers at the applicable contract price or potentially be subject to cover damages for any shortfall. If future shortfalls occur, we will work with our customer to identify possible other supply sources while we implement operating improvements at the facility, but we may not be successful in identifying alternative supplies and may be subject to paying the contract price for any shortfall or to cover damages, either of which could adversely affect our future revenues and profitability. Our long-term agreements also contain provisions requiring us to deliver coke that meets certain quality thresholds. Failure to meet these specifications could result in economic penalties, including price adjustments, the rejection of deliveries or termination of our agreements. To the extent that we do not meet the coal-to-coke yield standard in an agreement, we are responsible for the cost of the excess coal used in the cokemaking process.

Our coke and energy sales agreements contain force majeure provisions allowing temporary suspension of performance by our customers for the duration of specified events beyond the control of our customers. Declaration of force majeure, coupled with a lengthy suspension of performance under one or more coke or energy sales agreements, may seriously and adversely affect our cash flows, financial position and results of operations.

Failure to maintain effective quality control systems at our cokemaking facilities could have a material adverse effect on our results of operations.

The quality of our coke is critical to the success of our business. For instance, our coke sales agreements contain provisions requiring us to deliver coke that meets certain quality thresholds. If our coke fails to meet such specifications, we could be subject to significant contractual damages or contract terminations, and our sales could be negatively affected. The quality of our coke depends significantly on the effectiveness of our quality control systems, which, in turn, depends on a number of factors, including the design of our quality control systems, our quality-training program, our laboratories and our ability to ensure that our employees adhere to our quality control policies and guidelines. Any significant failure or deterioration of our quality control systems could have a material adverse effect on our results of operations.

Disruptions to our supply of coal and coal mixing services may reduce the amount of coke we produce and deliver, and if we are not able to cover the shortfall in coal supply or obtain replacement mixing services from other providers, our results of operations and profitability could be adversely affected.

Substantially all of the metallurgical coal used to produce coke at our cokemaking facilities is purchased from third-parties under one-year contracts. We cannot assure that there will continue to be an ample supply of metallurgical coal available that meet our quality specifications or that these facilities will be supplied without any significant disruption in coke production, as economic, environmental, and other conditions outside of our control may reduce our ability to source sufficient amounts of coal for our forecasted operational needs. If we are not able to make up the shortfalls resulting from such supply failures through purchases of coal from other sources, the failure of our coal suppliers to meet their supply commitments could materially and adversely impact our results of operations and, ultimately, impact the structural integrity of our coke oven batteries.

At our Granite City and Haverhill cokemaking facilities, we rely on third-parties to mix coals that we have purchased into coal mixes that we use to produce coke. We have entered into long-term agreements with coal mixing service providers that are coterminous with our coke sales agreements. However, there are limited alternative providers of coal mixing services and any disruptions from our current service providers could materially and adversely impact our results of operations. In addition, if our rail transportation agreements are terminated, we may have to pay higher rates to access rail lines or make alternative transportation arrangements.

Limitations on the availability and reliability of transportation, and increases in transportation costs, particularly rail systems, could materially and adversely affect our ability to obtain a supply of coal and deliver coke to our customers.

Our ability to obtain coal depends primarily on third-party rail systems and to a lesser extent river barges. If we are unable to obtain rail or other transportation services, or are unable to do so on a cost-effective basis, our results of operations 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. The loss of access to rail capacity could create temporary disruption until the access is restored, significantly impairing our ability to receive coal and resulting in materially decreased revenues. Our ability to open new cokemaking facilities may also be affected by the availability and cost of rail or other transportation systems available for servicing these facilities.

Our coke production obligations at our Jewell cokemaking facility and one half of our Haverhill cokemaking facility require us to deliver coke to certain customers via railcar. We have entered into long-term rail transportation agreements to meet these obligations. Disruption of these transportation services because of weather-related problems, including those related to climate change, mechanical difficulties, train derailments, infrastructure damage, strikes, lock-outs, lack of fuel or maintenance items, fuel costs, transportation delays, accidents, terrorism, domestic catastrophe or other events could temporarily, or over the long-term, impair our ability to produce coke, and therefore, could materially and adversely affect our business and results of operations.

If we are unable to effectively protect our intellectual property, third parties may use our technology, which would impair our ability to compete in our markets.

Our future success will depend in part on our ability to obtain and maintain meaningful patent protection for certain of our technologies and products throughout the world. The degree of future protection for our proprietary rights is uncertain. We rely on patents to protect our intellectual property portfolio and to enhance our competitive position. However, our presently pending or future patent applications may not issue as patents, and any patent previously issued to us or our subsidiaries may be challenged, invalidated, held unenforceable or circumvented. Furthermore, the claims in patents that have been issued to us or our subsidiaries or that may be issued to us in the future may not be sufficiently broad to prevent third parties from using cokemaking technologies and heat recovery processes similar to ours. In addition, the laws of various foreign countries in which we plan to compete may not protect our intellectual property to the same extent as do the laws of the U.S. If we fail to obtain adequate patent protection for our proprietary technology, our ability to be commercially competitive may be materially impaired.

We are subject to certain political or country risks due to the Vitória, Brazil cokemaking facility that could adversely affect our financial results.

The Vitória cokemaking facility is owned by ArcelorMittal Brazil. We earn income from the Vitória, Brazil operations through licensing and operating fees earned at the Brazilian cokemaking facility payable to us under long-term agreements with ArcelorMittal Brazil. These revenues depend on continuing operations and, in some cases, certain minimum production levels being achieved at the Vitória cokemaking facility. In the past, the Brazilian economy has been characterized by frequent and occasionally extensive intervention by the Brazilian government and unstable economic cycles. The Brazilian government has changed in the past, and may change monetary, taxation, credit, tariff and other policies to influence Brazil’s economy in the future. If the operations at the Vitória cokemaking facility are interrupted or if certain minimum production levels are not achieved, we will not be able to earn the same licensing and operating fees as we are currently earning, which could have an adverse effect on our financial position, results of operations and cash flows.

Additionally, the Vitória, Brazil operations require us to comply with a number of U.S. and international laws and regulations, including those involving anti-bribery, anti-corruption and anti-fraud. In particular, our international operations are subject to U.S. and foreign anti-corruption laws and regulations, including the regulations imposed by the Foreign Corrupt Practices Act (“FCPA”), which generally prohibits issuers and their strategic or local partners, agents or representatives, which we refer to as our intermediaries (even if those intermediaries are not themselves subject to the FCPA or other similar laws), from making improper payments to foreign officials for the purpose of obtaining or keeping business or obtaining an improper business benefit.

We take precautions to comply with these laws. However, these precautions may not protect us against liability, particularly as a result of actions by our intermediaries through whom we have exposure under these anti-bribery, anti-corruption and anti-fraud laws even though we may have limited or no ability to control such intermediaries. Any violations of such laws could be punishable by criminal fines, imprisonment, civil penalties, disgorgement of profits, injunctions and exclusion from government contracts, as well as other remedial measures. Investigations of alleged violations can be very expensive, disruptive and damaging to our reputation and could negatively impact our stock price. Failure by us or our intermediaries to comply with the foregoing or other anti-bribery, anti-corruption and anti-fraud laws could adversely impact our results of operations, financial position, and cash flows, damage our reputation and negatively impact our stock price.

Risks Related to Our Logistics Business

The growth and success of our logistics business depends upon our ability to find and contract for adequate throughput volumes, and an extended decline in demand for coal could affect the customers for our logistics business adversely. As a consequence, the operating results and cash flows of our logistics business could be materially and adversely affected.

The financial results of our logistics business segment are significantly affected by the demand for both thermal coal and metallurgical coal. An extended decline in our customers’ demand for either thermal or metallurgical coals, including as a result of legislation or regulations promoting renewable energy or limiting carbon emissions from the energy sector, could result in a reduced need for the coal mixing, terminalling and transloading services we offer, thus reducing throughput and utilization of our logistics assets. Demand for such coals may fluctuate due to factors beyond our control:

• Thermal coal demand: may be impacted by changes in the energy consumption pattern of industrial consumers, electricity generators and residential users, as well as weather conditions and extreme temperatures. The amount of thermal coal consumed for electric power generation is affected primarily by the overall demand for electricity, the availability, quality and price of competing fuels for power generation, including natural gas, and governmental regulation. For example, state and federal mandates and market demand for increased use of electricity from renewable energy sources, or mandates for the retrofitting of existing coal-fired generators with pollution control systems, could adversely impact the demand for thermal coal. Finally, unusually warm winter weather may reduce the commercial and residential needs for heat and electricity which, in turn, may reduce the demand for thermal coal; and
• Metallurgical coal demand: may be impacted adversely by economic downturns resulting in decreased demand for steel and an overall decline in steel production. A decline in blast furnace production of steel may reduce the demand for furnace coke, an intermediate product made from metallurgical coal. Decreased demand for metallurgical coal also may result from increased steel industry utilization of processes that do not use, or reduce the need for, furnace coke, such as electric arc furnaces, or blast furnace injection of pulverized coal or natural gas.

Additionally, fluctuations in the market price of coal can greatly affect production rates and investments by third-parties in the development of new and existing coal reserves. Mining activity may decrease as spot coal prices decrease. We have no control over the level of mining activity by coal producers, which may be affected by prevailing and projected coal prices, demand for hydrocarbons, the level of coal reserves, geological considerations, governmental regulation and the availability and cost of capital. A material decrease in coal mining production in the areas of operation for our logistics business, whether as a result of depressed commodity prices or otherwise, could result in a decline in the volume of coal processed through our logistics facilities, which would reduce our revenues and operating income.

Decreased demand for thermal or metallurgical coals, and extended or substantial price declines for coal could adversely affect our operating results for future periods and our ability to generate cash flows necessary to improve productivity and expand operations. The cash flows associated with our logistics business may decline unless we are able to secure new volumes of coal or other dry bulk products, by attracting additional customers to these operations. Future growth and profitability of our logistics business segment will depend, in part, upon whether we can contract for additional coal and other bulk commodity volumes at a rate greater than that of any decline in volumes from existing customers. Accordingly, decreased demand for coal, or other bulk commodities, or a decrease in the market price of coal, or other bulk commodities, could have a material adverse effect on the results of operations or financial condition of our logistics business.

The geographic location of CMT could expose us to potential significant liabilities, including operational hazards and unforeseen business interruptions, that could substantially and adversely affect our future financial performance.

CMT is located in the Gulf Coast region, and its operations are subject to operational hazards and unforeseen interruptions, including interruptions from hurricanes, floods, or other potential effects of climate change, which have historically impacted the region with some regularity. If any of these events were to occur, we could incur substantial losses because of personal injury or loss of life, severe damage to and destruction of property and equipment, and pollution or other environmental damage resulting in curtailment or suspension of our related operations.

Risks Related to Indebtedness, Liquidity and Financial Position

We may need additional capital in the future to meet our financial obligations and to pursue our business objectives. Additional capital may not be available on favorable terms, or at all, which could compromise our ability to meet our financial obligations and grow our business.

We may need to raise additional capital to fund operations in the future or to finance acquisitions or other business objectives. Such additional capital may not be available on favorable terms or at all. Lack of sufficient capital resources could significantly limit our ability to meet our financial obligations or to take advantage of business and strategic opportunities. Any additional capital raised through the sale of equity or convertible debt securities would dilute stock ownership, and any new equity securities we issue could have rights, preferences and privileges superior to those of holders of our common stock. Any debt financing we secure in the future could involve restrictive covenants relating to our capital raising activities and other financial and operational matters, which may make it more difficult for us to obtain additional capital and to pursue business opportunities. If we are unable to obtain adequate financing or financing on terms satisfactory to us when we require it, we may be required to delay or reduce the scope of our business strategy.

We may face material debt maturities which may adversely affect our consolidated financial position.

As of December 31, 2023, we have no consolidated debt maturing over the next five years. See Note 11 to our consolidated financial statements. However, we may enter into debt agreements throughout the course of the fiscal year which could create material debt maturities. We may not be able to refinance this debt, or may be forced to do so on terms substantially less favorable than our currently outstanding debt. We may be forced to delay or not make capital expenditures, which may adversely affect our competitive position and financial results.

We may be adversely affected by the effects of inflation.

Inflation has the potential to adversely affect our liquidity, business, financial condition and results of operations by increasing our overall cost structure. The existence of inflation in the economy has resulted in, and may continue to result in, higher interest rates and capital costs, increased costs of labor, weakening exchange rates and other similar effects. Although we may take measures to mitigate the impact of this inflation, if these measures are not effective, our business, financial condition, results of operations and liquidity could be materially adversely affected. Even if such measures are effective, there could be a difference between the timing of when these beneficial actions impact our results of operations and when the cost of inflation is incurred.

Our level of indebtedness could adversely affect our financial condition and prevent us from fulfilling our obligations under our credit facilities and other debt documents. Further, our credit facilities contain operating and financial covenants that may restrict our business and financing activities.

Subject to the limits contained in our credit agreements and our other debt instruments, we may be able to incur additional debt from time to time to finance working capital, capital expenditures, investments or acquisitions, or for other purposes. If we do so, the risks related to our level of debt could intensify. Specifically, a higher level of debt could have important consequences, including:

• making it more difficult for us to satisfy our obligations with respect to the notes and our other debt;
• limiting our ability to obtain additional financing to fund future working capital, capital expenditures, acquisitions, distributions or other general corporate requirements;
• requiring a substantial portion of our cash flows to be dedicated to debt service payments instead of other purposes, thereby reducing the amount of cash flows available for the payment of dividends, working capital, capital expenditures, acquisitions and other general corporate purposes;
• increasing our vulnerability to general adverse economic and industry conditions;
• exposing us to the risk of increased interest rates as certain of our borrowings, including borrowings under the credit facilities, are at variable rates of interest;
• limiting our flexibility in planning for and reacting to changes in the industry in which we compete;
• placing us at a competitive disadvantage to other, less leveraged competitors; and
• increasing our cost of borrowing.

Our ability to meet our debt obligations and reduce our level of indebtedness depends upon our future performance and general economic, financial, business, and other factors, many of which are beyond our control. Factors affecting our ability to raise cash through an offering of our common stock or a refinancing of our debt include financial market conditions, the value of our assets, and our performance at the time we need capital.

In addition, the credit agreement governing our credit facilities contains restrictive covenants that limit our ability to engage in activities (such as incurring additional debt) that may be in our long-term best interest. Our failure to comply with those covenants could result in an event of default which, if not cured or waived, could result in the acceleration of all our debt. In the event of an acceleration of all our debt, we may not have sufficient cash on hand to repay the indebtedness in full or refinance such debt on favorable terms, or at all. Such event could materially adversely affect our business, financial condition and results of operations.

Risks Related to Our Legacy Coal Mining Business

Our former coal mining operations were subject to governmental regulations pertaining to employee health and safety and mandated benefits for retired coal miners. Following the divestiture of our coal mining operations, compliance with such regulations has continued to impose significant costs on our business.

Our former coal mining operations were subject to strict regulation by federal, state and local authorities with respect to environmental matters such as reclamation, and to matters such as employee health and safety and mandated benefits for retired coal miners. Even after divestiture of our coal mining business, compliance with these reclamation and benefits requirements has continued to impose significant costs on us. As a former coal mine operator, federal law requires us to secure payment of federal black lung benefits to claimants who were employees, and to contribute to a trust fund for payment of benefits and medical expenses to claimants who last worked in the coal industry before January 1, 1970. At December 31, 2023, our liabilities for coal workers’ black lung benefits totaled $58.2 million. Our business could be materially and adversely harmed if these liabilities, including the number and award size of claims, were increased. See “Item 1. Business-Legal and Regulatory Requirements-Regulation of Operations.”

General Risks

Sustained uncertainty in financial markets, or unfavorable economic conditions in the industries in which our customers operate, may lead to a reduction in the demand for our products and services, and adversely impact our cash flows, financial position or results of operations.

Sustained volatility and disruption in worldwide capital and credit markets in the U.S. and globally could restrict our ability to access the capital market at a time when we would like, or need, to raise capital for our business including for potential acquisitions, or other growth opportunities.

Deteriorating or unfavorable economic conditions in the industries in which our customers operate, such as steelmaking and electric power generation, may lead to reduced demand for steel products, coal, and other bulk commodities which, in turn, could adversely affect the demand for our products and services and negatively impact the revenues, margins and profitability of our business.

Labor disputes with the unionized portion of our workforce could affect us adversely. Union represented labor creates an increased risk of work stoppages and higher labor costs.

We rely, at one or more of our facilities, on unionized labor, and there is always the possibility that we may be unable to reach agreement on terms and conditions of employment or renewal of a collective bargaining agreement. When collective bargaining agreements expire or terminate, we may not be able to negotiate new agreements on the same or more favorable terms as the current agreements, or at all, and without production interruptions, including labor stoppages. If we are unable to negotiate the renewal of a collective bargaining agreement before its expiration date, our operations and our profitability could be adversely affected. A prolonged labor dispute, which may include a work stoppage, could adversely affect our ability to satisfy our customers’ orders and, as a result, adversely affect our operations, or the stability of production and reduce our future revenues, or profitability. It is also possible that, in the future, additional employee groups may choose to be represented by a labor union.

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

We have implemented recruitment, training and retention efforts to optimally staff our operations. Our ability to operate our business and implement our strategies depends in part on the efforts of our executive officers and other key employees. In addition, our future success will depend on, among other factors, our ability to attract and retain other qualified personnel. The loss of the services of any of our executive officers or other key employees or the inability to attract or retain other qualified personnel in the future could have a material adverse effect on our business or business prospects. With respect to our represented employees, we may be adversely impacted by the loss of employees who retire or obtain other employment during a layoff or a work stoppage.

We currently are, and likely will be, subject to litigation, the disposition of which could have a material adverse effect on our cash flows, financial position or results of operations.

The nature of our operations exposes us to possible litigation claims in the future, including disputes relating to our operations and commercial and contractual arrangements. Although we make every effort to avoid litigation, these matters are not totally within our control. We will contest these matters vigorously and have made insurance claims where appropriate, but because of the uncertain nature of litigation and coverage decisions, we cannot predict the outcome of these matters. Litigation is very costly, and the costs associated with prosecuting and defending litigation matters could have a material adverse effect on our financial condition and profitability. In addition, our profitability or cash flow in a particular period could be affected by an adverse ruling in any litigation currently pending in the courts or by litigation that may be filed against us in the future. We are also subject to significant environmental and other government regulation, which sometimes results in various administrative proceedings. For additional information, see “Item 3. Legal Proceedings.”

Security breaches and other information systems failures could disrupt our operations, compromise the integrity of our data, expose us to liability, cause increased expenses and cause our reputation to suffer, any or all of which could have a material and adverse effect on our business or financial position.

Our business is dependent on financial, accounting and other data processing systems and other communications and information systems, including our enterprise resource planning tools. We process a large number of transactions on a daily basis and rely upon the proper functioning of computer systems. If a key system were to fail or experience unscheduled downtime for any reason, our operations and financial results could be affected adversely. Our systems could be damaged or interrupted by a security breach, terrorist attack, fire, flood, power loss, telecommunications failure or similar event. Our disaster recovery plans may not entirely prevent delays or other complications that could arise from an information systems failure. Our business interruption insurance may not compensate us adequately for losses that may occur.

In the ordinary course of our business, we collect and store sensitive data in our data centers, on our networks, and in our cloud vendors. In addition, we rely on third party service providers, for support of our information technology systems, including the maintenance and integrity of proprietary business information and other confidential company information and data relating to customers, suppliers and employees. The secure processing, maintenance and transmission of this information is critical to our operations and business strategy. We have instituted data security measures for confidential company information and data stored on electronic and computing devices, whether owned or leased by us or a third party vendor. However, despite such measures, there are risks associated with customer, vendor, and other third-party access and our information technology and infrastructure may be vulnerable to attacks by hackers or breached due to: employee error or malfeasance, failure of third parties to meet contractual, regulatory and other obligations to us, or other disruptions.

Any such breach could compromise our networks and the information stored there could be accessed, publicly disclosed, lost or stolen. Any such access, disclosure or other loss of information could result in legal claims or proceedings, liability under laws that protect the privacy of personal information, and regulatory penalties, disrupt our operations, and damage our reputation, which could materially and adversely affect our business and financial position.

We are exposed to, and may be adversely affected by, interruptions to our computer and information technology systems and sophisticated cyber-attacks.

We rely on our information technology systems and networks in connection with many of our business activities. Some of these networks and systems are managed by third-party service providers and are not under our direct control. Our operations routinely involve receiving, storing, processing and transmitting sensitive information pertaining to our business, customers, dealers, suppliers, employees and other sensitive matters. Cyber-attacks could materially disrupt operational systems; result in loss of trade secrets or other proprietary or competitively sensitive information; compromise personally identifiable information regarding customers or employees; and jeopardize the security of our facilities. A cyber-attack could be caused by malicious outsiders using sophisticated methods to circumvent firewalls, encryption and other security defenses. Because techniques used to obtain unauthorized access or to sabotage systems change frequently and generally are not recognized until they are launched against a target, we may be unable to anticipate these techniques or to implement adequate preventative measures. Information technology security threats, including security breaches, computer malware and other cyber-attacks are increasing in both frequency and sophistication and could create financial liability, subject us to legal or regulatory sanctions or damage our reputation with customers, dealers, suppliers and other stakeholders. We continuously seek to maintain a robust program of information security and controls, but a cyber-attack could have a material adverse effect on our competitive position, reputation, results of operations, financial condition and cash flows. As cyber-attacks continue to evolve, we may be required to expend additional resources to continue to modify or enhance our protective measures or to investigate and remediate any information security vulnerabilities.

We are or may become subject to privacy and data protection laws, rules and directives relating to the processing of personal data in the states and countries where we operate.

The growth of cyber-attacks has resulted in an evolving legal landscape which imposes costs that are likely to increase over time. For example, new laws and regulations governing data privacy and the unauthorized disclosure of confidential information, including the European Union General Data Protection Regulation and recent California legislation (which, among other things, provides for a private right of action), pose increasingly complex compliance challenges and could potentially elevate our costs over time. Any failure by us to comply with such laws and regulations could result in penalties and liabilities. It is also possible under certain legislation that if we acquire a company that has violated or is not in compliance with applicable data protection laws, we may incur significant liabilities and penalties as a result.

Cybersecurity Risk Management, Strategy, and Governance

We recognize the importance of assessing, identifying, and managing material risks associated with cybersecurity threats, as such term is defined in Item 106(a) of Regulation S-K, to protect the confidentiality, integrity and availability of our critical systems and information. Our enterprise risk management program considers cybersecurity threats as part of our overall risk assessment process. We perform these risk assessments to inform our risk mitigation strategies and prioritize cybersecurity initiatives. Our cybersecurity risk assessment process includes network and endpoint monitoring, vulnerability assessments, and penetration testing, and we believe helps identify our cybersecurity threat risks by aligning our processes to standards set by the National Institute of Standards and Technology (“NIST”). This does not imply that we meet any particular technical standards, specifications, or requirements, only that we use the NIST standards as a guide to help us identify, assess, and manage cybersecurity risks relevant to our business. The results of our cybersecurity assessments are regularly shared with senior management and the Board of Directors. Additionally, we have implemented technologies, controls and processes to aid in our efforts to assess, identify, manage, and monitor material cybersecurity risks, their severity, and potential mitigation. We regularly review and update our cybersecurity processes to help address the evolving cybersecurity landscape and legal requirements, providing clear guidelines for our employees and third-party service providers.

Governance Structure and Risk Management Functions

Cybersecurity is an integral part of our risk management processes. Our cross-functional risk management team evaluates cybersecurity risks alongside other operational, financial, and reputational risks, facilitating effective resource allocation and coordinated mitigation strategies. In 2021, we updated our Audit Committee charter to memorialize the Committee’s role in reviewing cybersecurity matters. The Audit Committee oversees the initial assessment of cybersecurity threats as well as the Company’s approach to management and mitigation of such risks, compliance with industry standards related to cybersecurity, and the Company’s public disclosures related to cybersecurity matters. In addition, our Board of Directors devotes regular attention to oversight of cybersecurity risks. At least annually, the entire Board of Directors receives an update from our Chief Information Officer (“CIO”) detailing our cybersecurity threat risk management and strategy processes. This update covers topics such as data security posture, results from assessments conducted by third parties, progress towards security goals, and any material cybersecurity developments, as well as steps taken in response to such developments. Our governance structure allows senior management and the Board of Directors to also remain involved in our cybersecurity strategy and risk management oversight, creating a comprehensive approach to our risk management.

Cybersecurity Leadership and Communication

Our CIO has experience in various roles implementing effective information and cybersecurity programs. The CIO reports to the Company’s Senior Vice President and Chief Financial Officer and maintains open channels of communication with the broader senior management team and the Board of Directors. The CIO leads our cybersecurity initiatives and is responsible for implementing our cybersecurity strategy, managing daily operations, coordinating incident responses, and providing regular updates to management, the Audit Committee and the Board of Directors regarding the Company’s cybersecurity status and risk assessments.

External Support and Third-Party Risk Management

Management continues to take steps to enhance our data security infrastructure and defenses. Our processes also address cybersecurity threat risks associated with using third-party service providers, including those in our supply chain or who have access to our customer and employee data, our information systems, or the facilities that house such systems or data. We engage outside third-party experts, cybersecurity advisors, and auditors to conduct regular risk assessments, penetration testing, and vulnerability analyses. Our enterprise risk management and cybersecurity-specific risk identification programs include consideration of third-party risks and informs our selection and oversight of third-party service providers. We conduct appropriate due diligence on third-party service providers, vendors, and partners before establishing relationships with them, and we monitor such relationships on an ongoing basis. We also periodically review the Company’s cyber insurance policies to ensure appropriate coverage.

Incident Response and Vulnerability Management

In the event of a cybersecurity incident, our incident response plans are designed to respond with an incident response team to address any breaches. Our ongoing vulnerability management program complements our incident response capabilities. It includes periodic scanning, risk assessment, and patch management to address system and network vulnerabilities and help ensure that our infrastructure remains resilient against evolving threats.

As part of our risk factor disclosures at Item 1A of this Annual Report on Form 10-K, and in our MD&A at Item 7 of this Annual Report on Form 10-K, we describe whether and how risks from identified cybersecurity threats, including any previous incidents, have materially affected or are reasonably likely to materially affect our business strategy, results of operations, or financial condition. These disclosures are incorporated by reference herein. There can be no assurance that our cybersecurity risk management program and processes, including our policies, controls or procedures, will be fully implemented, complied with or effective in protecting our systems and information. Based on the information we have as of the date of this Annual Report on Form 10-K, we do not believe any risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, have materially affected or are reasonably likely to materially affect us, including our business strategy, results of operations or financial condition. This includes penalties and settlements, of which there were none.

We own the following real property as of December 31, 2023:

• Approximately 900 acres in Vansant (Buchanan County), Virginia on which the Jewell cokemaking facility is located, along with the offices, warehouse and support buildings for our Jewell coke affiliates as well as other general property holdings and unoccupied land.
• Approximately 400 acres in Franklin Furnace (Scioto County), Ohio, at and around the area where the Haverhill cokemaking facility (both the first and second phases) is located.
• Approximately 45 acres in Granite City (Madison County), Illinois, adjacent to the U.S. Steel Granite City Works facility, on which the Granite City cokemaking facility is located. Upon the earlier of ceasing production at the facility or the end of 2044, U.S. Steel has the right to repurchase the property, including the facility, at the fair market value of the land. Alternatively, U.S. Steel may require us to demolish and remove the facility and remediate the site to original condition upon exercise of its option to repurchase the land.
• Approximately 250 acres in Middletown (Butler County), Ohio near the Cliffs Steel Middletown Works facility, on which the Middletown cokemaking facility is located.
• Approximately 180 acres in Ceredo (Wayne County), West Virginia on which KRT has two terminals for its mixing and/or handling services along the Ohio and Big Sandy Rivers.
• Approximately 175 acres in Convent (St. James Parish), Louisiana, on which CMT is located.

We lease the following real property as of December 31, 2023:

• Approximately 90 acres of land located in East Chicago (Lake County), Indiana, on which the Indiana Harbor cokemaking facility is located and the coal handling and/or mixing facilities (Lake Terminal) that service the Indiana Harbor cokemaking facility. The leased property is inside the Cliffs Steel Indiana Harbor Works facility and is part of an enterprise zone. As lessee of the property, we are responsible for restoring the leased property to a safe and orderly condition.
• Approximately 310 acres of land located in Buchanan County, Virginia at and around the area where our Jewell coal handling terminal is located.
• Approximately 30 acres in Belle (Kanawha County), West Virginia, on which KRT has a terminal for its mixing and/or handling services along the Kanawha River.
• Our corporate headquarters is located in leased office space in Lisle, Illinois under a 9 year lease that commenced in 2021.

While the Company completed the disposal of its coal mining business in April 2016, we continue to have rights to small parcels of land, mineral rights and coal mining rights for approximately 5 thousand acres of land in Buchanan and Russell Counties, Virginia. These agreements convey mining rights to us in exchange for payment of certain immaterial royalties and/or fixed fees.

The information presented in Note 12 to our consolidated financial statements within this Annual Report on Form 10-K is incorporated herein by reference.

Many legal and administrative proceedings are pending or may be brought against us arising out of our current and past operations, including matters related to commercial and tax disputes, product liability, employment claims, personal injury claims, premises-liability claims, allegations of exposures to toxic substances and general environmental claims. Although the ultimate outcome of these proceedings cannot be ascertained at this time, it is reasonably possible that some of them could be resolved unfavorably to us. Our management believes that any liabilities that may arise from such matters would not likely be material in relation to our business or our consolidated financial position, results of operations or cash flows at December 31, 2023.

This Annual Report on Form 10-K contains certain forward-looking statements, as defined in the Private Securities Litigation Reform Act of 1995. This discussion contains forward-looking statements about our business, operations and industry that involve risks and uncertainties, such as statements regarding our plans, objectives, expected future developments, expectations and intentions, and they involve known and unknown risks that are difficult to predict. As a result, our future results and financial condition may differ materially from those we currently anticipate as a result of the factors we describe under “Cautionary Statement Concerning Forward-Looking Statements” and “Risk Factors.”

This Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) is based on financial data derived from the financial statements prepared in accordance with United States generally accepted accounting principles (“GAAP”) and certain other financial data that is prepared using a non-GAAP measure. For a reconciliation of the non-GAAP measure to its most comparable GAAP component, see “Non-GAAP Financial Measures” in this Item 7.

Our MD&A is provided in addition to the accompanying consolidated financial statements and notes to assist readers in understanding our results of operations, financial condition and cash flows. Our results of operations include reference to our business operations and market conditions, which are further described in Part I of this document.

2023 Overview

Our consolidated results of operations in 2023 were as follows:

(Dollars in millions)

(1) See “Non-GAAP Financial Measures” in this Item 7 below for both the definition of Adjusted EBITDA and the reconciliation from GAAP to the non-GAAP measurement.

Operating results during the year ended December 31, 2023 primarily reflects lower margin on our non-contracted blast coke sales, unfavorable energy pricing at our Haverhill facility and lower transloading volumes in our Logistics segment. These decreases were partially offset by favorable coal-to-coke yields on our long-term, take-or-pay agreements and favorable pricing on our foundry coke sales. Net income for the current year period was further impacted by the establishment of a valuation allowance on deferred tax assets attributable to existing foreign tax credit carryforwards. Operating cash flows during the current period primarily reflect a favorable year-over-year change in primary working capital.

We returned meaningful capital to our shareholders through the declaration and payment of a dividend during each quarter of 2023, increasing from $0.08 per share during the first half of the year to $0.10 per share during the second half of the year, representing a quarterly increase of 25 percent. Additionally, we reduced total debt by approximately $44 million in 2023.

Recent Developments

• 2023 Indiana Harbor Contract Renewal. In April 2023, the Indiana Harbor long-term, take-or-pay agreement with Cliffs Steel was extended to September 30, 2035. Under the extended agreement, Indiana Harbor will continue to supply 1,220 thousand tons to Cliffs Steel annually. Reimbursement of certain operating and maintenance expenses under the contract are fixed subject to annual adjustment based on an inflation index. Other key provisions of the agreement, including the pass-through of coal costs, remain unchanged.

Consolidated Results of Operations

The following section includes year-over-year analysis of consolidated results of operations for the year ended December 31, 2023 as compared to the year ended December 31, 2022. See “Analysis of Segment Results” later in this Item 7 for further details of these results. Refer to Management's Discussion and Analysis of Financial Condition and Results of Operations in our 2022 Annual Report on Form 10-K for the year-over-year analysis of consolidated results of operations for the year ended December 31, 2022 as compared to the year ended December 31, 2021.

(Dollars in millions)

Sales and Other Operating Revenue and Costs of Products Sold and Operating Expenses. Sales and other operating revenue and costs of products sold and operating expenses increased in 2023 as compared to 2022, primarily driven by the pass-through of higher coal prices in our Domestic Coke segment. Additionally, revenues further benefited from higher volumes on our long-term, take-or-pay agreements. These increases to sales and other operating revenue were partially offset by lower volumes and unfavorable pricing on our non-contracted blast coke sales.

Selling, General and Administrative Expenses. The decrease in selling, general and administrative expense primarily reflects lower employee related expenses, lower cost of professional services and lower transaction costs incurred as part of the granulated pig iron project. These lower costs were partially offset by valuation adjustments primarily as a result of changes in discount rates on certain legacy liabilities, which increased legacy costs by $5.7 million as compared to the prior year.

Depreciation and Amortization Expense. Depreciation and amortization expense was reasonably consistent with the prior year period.

Interest Expense, net. Interest expense, net, benefited in 2023 from lower average debt balances during the current year period and higher interest income of $2.0 million.

Income Tax Expense. Income tax expense during 2023 primarily reflects the establishment of a valuation allowance on deferred tax assets attributable to existing foreign tax credit carryforwards, which was a portion of a valuation allowance released during the third quarter of 2022, resulting in $8.4 million of deferred tax expense. The establishment of the valuation allowance during 2023 was the result of changes in tax regulations. See Note 4 to our consolidated financial statements for further detail.

Noncontrolling Interest. Net income attributable to noncontrolling interests represents a 14.8 percent third-party interest in our Indiana Harbor cokemaking facility and fluctuates with the financial performance of that facility.

Results of Reportable Business Segments

We report our business results through three reportable segments:

• Domestic Coke consists of our Jewell facility, located in Vansant, Virginia, our Indiana Harbor facility, located in East Chicago, Indiana, our Haverhill facility, located in Franklin Furnace, Ohio, our Granite City facility located in Granite City, Illinois, and our Middletown facility located in Middletown, Ohio.
• Brazil Coke consists of operations in Vitória, Brazil, where we operate the ArcelorMittal Brazil cokemaking facility.
• Logistics consists of CMT, located in Convent, Louisiana, KRT, located in Ceredo and Belle, West Virginia, and Lake Terminal, located in East Chicago, Indiana. Lake Terminal is located adjacent to our Indiana Harbor cokemaking facility.

The operations of each of our reportable segments are described in Part I of this Annual Report on Form 10-K. The Company elected to combine Dismal River Terminal (“DRT”) operations into the Jewell cokemaking operations in the Domestic Coke segment beginning January 1, 2023. The DRT results were included in the Logistics segment in 2022 and are not recast.

Corporate expenses that can be identified with a segment have been included in determining segment results. The remainder is included in Corporate and Other, including activity from our legacy coal mining business, which is not considered a reportable segment and, therefore, not included in our segment information in Note 19. However, we have included Corporate and Other within our operating data below.

Management believes Adjusted EBITDA is an important measure of operating performance, which is used by the chief operating decision maker as one of the measurements to evaluate the performance of each of our reportable segments. Adjusted EBITDA should not be considered a substitute for the reported results prepared in accordance with GAAP. See the “Non-GAAP Financial Measures” section below for both the definition of Adjusted EBITDA and the reconciliation from GAAP to the non-GAAP measurement.

Segment Operating Data

The following table sets forth financial and operating data by segment for the years ended December 31, 2023 and 2022:

(Dollars in millions, except per ton amounts)

(1) See the “Non-GAAP Financial Measures” section below for both the definition of Adjusted EBITDA and the reconciliation from GAAP to the non-GAAP measurement.

(2) Corporate and Other, net is not a reportable segment.

(3) The production of foundry coke tons does not replace blast furnace coke tons on a ton for ton basis, as foundry coke requires longer coking time. The Domestic Coke capacity utilization is calculated assuming a single ton of foundry coke replaces approximately two tons of blast furnace coke.

(4) Reflects Domestic Coke Adjusted EBITDA divided by Domestic Coke sales volumes.

Analysis of Segment Results

Domestic Coke

The following table explains year-over-year changes in our Domestic Coke segment's sales and other operating revenues and Adjusted EBITDA results:

(Dollars in millions)

(1) Higher volumes on our long-term, take-or-pay agreements increased both revenues and Adjusted EBITDA during 2023. These higher volumes were mostly offset by lower volumes on non-contracted blast coke sales.

(2) Revenues increased primarily as a result of the pass-through of higher coal prices on our long-term, take-or-pay agreements. Adjusted EBITDA decreased primarily due to lower margins on our non-contracted blast coke sales. These decreases to Adjusted EBITDA were partially offset by favorable coal-to-coke yields on our long-term, take-or-pay agreements and favorable pricing on foundry coke sales.

(3) Energy and other decreased primarily as a result of unfavorable energy pricing at our Haverhill facility.

Logistics

The following table explains year-over-year changes in our Logistics segment's sales and other operating revenues, exclusive of intersegment sales, and Adjusted EBITDA results:

(Dollars in millions)

Intersegment sales and other operating revenue in our Logistics segment were $22.1 million and $28.9 million as of December 31, 2023 and 2022, respectively. Adjusted EBITDA presented above is inclusive of the impact of intersegment transactions.

(1) Volumes decreased as a result of lower demand at CMT driven by weakened thermal coal markets and the short-term idling of a customer mine during the fourth quarter of 2023. Additionally, Adjusted EBITDA in the current year period reflects the absence of DRT volumes.

(2) Revenues and Adjusted EBITDA increased as a result of higher transloading pricing.

(3) Revenues and Adjusted EBITDA decreased as a result of unfavorable ancillary revenue, which was a result of lower volumes at CMT. This decrease in Adjusted EBITDA was more than offset by the absence of costs associated with DRT in the current year period.

Brazil Coke

Sales and other operating revenue decreased $2.8 million, or 7 percent, to $35.2 million in 2023 compared to $38.0 million in 2022. Adjusted EBITDA decreased $5.4 million, or 37 percent, to $9.1 million in 2023 compared to $14.5 million in 2022. Decreases in sales and other operating revenue and Adjusted EBITDA were primarily due to the absence of technology fees, which expired at the end of 2022.

Corporate and Other

Corporate and Other Adjusted EBITDA decreased $2.5 million, or 8 percent, to a loss of $32.4 million in 2023 compared to a loss of $29.9 million in 2022. This decrease was primarily driven by valuation adjustments as a result of changes in discount rates on certain legacy liabilities, which increased legacy costs by $5.7 million, partially offset by lower employee related expenses and lower cost of professional services in the current year period.

Non-GAAP Financial Measures

In addition to the GAAP results provided in this Annual Report on Form 10-K, we have provided a non-GAAP financial measure, Adjusted EBITDA. Our management, as well as certain investors, use this non-GAAP measure to analyze our current and expected future financial performance. This measure is not in accordance with, or a substitute for, GAAP and may be different from, or inconsistent with, non-GAAP financial measures used by other companies.

The Company evaluates the performance of its segments based on segment Adjusted EBITDA, which is defined as earnings before interest, taxes, depreciation and amortization (“EBITDA”), adjusted for any impairments, restructuring costs, gains or losses on extinguishment of debt, and/or transaction costs (“Adjusted EBITDA”). EBITDA and Adjusted EBITDA do not represent and should not be considered alternatives to net income or operating income under GAAP and may not be comparable to other similarly titled measures in other businesses.

Management believes Adjusted EBITDA is an important measure in assessing operating performance. Adjusted EBITDA provides useful information to investors because it highlights trends in our business that may not otherwise be apparent when relying solely on GAAP measures and because it eliminates items that have less bearing on our operating performance. EBITDA and Adjusted EBITDA are not measures calculated in accordance with GAAP, and they should not be considered a substitute for net income, or any other measure of financial performance presented in accordance with GAAP. Additionally, other companies may calculate Adjusted EBITDA differently than we do, limiting its usefulness as a comparative measure.

Reconciliation of Non-GAAP Financial Measures

Below is a reconciliation of Adjusted EBITDA to net income, which is its most directly comparable financial measure calculated and presented in accordance with GAAP:

(Dollars in millions)

(1) Costs incurred as part of the granulated pig iron project with U.S. Steel.

Liquidity and Capital Resources

Our primary liquidity needs are to fund working capital, fund investments, service our debt, maintain cash reserves and replace partially or fully depreciated assets and other capital expenditures. Our sources of liquidity include cash generated from operations, borrowings under our revolving credit facility (“Revolving Facility”) and, from time to time, debt and equity offerings. We believe our current resources are sufficient to meet our working capital requirements for our current business for at least the next 12 months and thereafter for the foreseeable future. As of December 31, 2023, we had $140.1 million of cash and cash equivalents and $350.0 million of borrowing availability under our Revolving Facility.

We may, from time to time, seek to retire or purchase additional amounts of our outstanding equity and/or debt securities through cash purchases and/or exchanges for other securities, in open market purchases, privately negotiated transactions or otherwise. Such repurchases or exchanges, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved may be material. Refer to further liquidity discussion in “Part II - Item 5 - Market for Registrant's Common Equity, Related Stockholders Matters and Issuer Purchases of Equity Securities.”

During the first quarter of 2020, the U.S. Department of Labor's Division of Coal Mine Workers' Compensation (“DCMWC”) requested SunCoke provide additional collateral of approximately $32 million to secure certain of its black lung obligations. SunCoke exercised its right to appeal the DCMWC’s determination and provided additional information supporting the Company’s position in May 2020 and February 2021. If the Company’s appeal is unsuccessful, the Company may be required to provide additional collateral to receive its self-insurance reauthorization from the DCMWC, which could potentially reduce the Company’s liquidity. Additionally, on January 19, 2023, the Department of Labor issued a new proposed rule that would require self-insured companies to post collateral in the amount of 120 percent of the company's total expected lifetime black lung obligations as determined by the DCMWC. While this new proposed rule is not effective, if finalized, it could potentially reduce the Company's liquidity. We submitted comments on this proposed rule and continue to monitor any impact to the Company. See further discussion in Note 12 to our consolidated financial statements.

Cash Flow Summary

The following table sets forth a summary of the net cash provided by (used in) operating, investing and financing activities for the years ended December 31, 2023 and 2022:

(Dollars in millions)

Cash Provided by Operating Activities

Net cash provided by operating activities increased $40.1 million to $249.0 million in 2023 as compared to 2022. The increase primarily reflects a favorable year-over-year change in primary working capital, which is comprised of accounts receivable, inventories, and accounts payable, driven by the timing of receipts from customers and the impact of the changes in coal prices. The current year period was further impacted by an increase in deferred income tax expense relating to new regulations impacting foreign tax credit utilization. See Note 4 to our consolidated financial statements for further detail on the change in deferred income tax expense. These favorable impacts were partially offset by lower operating results and higher payments made for employee related expenses in the current period.

Cash Used in Investing Activities

Net cash used in investing activities increased $39.0 million to $109.2 million in 2023 as compared to 2022 primarily driven by ongoing capital expenditures related to upgrades of our assets in order to improve long-term reliability and operational performance as well as increased spending on the foundry expansion project in the current year period. Refer to Capital Requirements and Expenditures below for further detail.

Cash Used in Financing Activities

Net cash used in financing activities decreased $22.8 million to $89.7 million in 2023 as compared to $112.5 million in 2022. This decrease in net cash used in financing activities was primarily driven by lower net repayments of $45.0 million on the Revolving Facility in the current year period. This decrease was offset by an increase in dividends paid of $7.1 million as compared to the prior year period, primarily as a result of an increase in the dividend per share amount, as well as higher cash distributions made to noncontrolling interests of $7.4 million in the current year period. The current year period was also impacted by higher repayments on financing obligations of $5.6 million, resulting from the early buyout on a sale leaseback arrangement, discussed further in Note 11 to our consolidated financial statements.

Dividends

In addition to the $30.7 million in dividends paid to our shareholders during 2023, on February 1, 2024, SunCoke's Board of Directors declared a cash dividend of $0.10 per share of the Company's common stock. This dividend will be paid on March 1, 2024, to stockholders of record on February 15, 2024. See further discussion in “Item 5. Market for Registrant’s Common Equity, Related Stockholders Matters and Issuer Purchases of Equity Securities.”

Covenants

As of December 31, 2023, we were in compliance with all applicable debt covenants. We do not anticipate a violation of these covenants nor do we anticipate that any of these covenants will restrict our operations or our ability to obtain additional financing. See Note 11 to our consolidated financial statements for details on debt covenants.

Credit Rating

In May 2023, S&P Global Ratings reaffirmed our corporate credit rating of BB- (stable). In November 2023, Moody’s Investors Service reaffirmed our corporate credit rating of B1 (positive).

Contractual Obligations

As of December 31, 2023, significant contractual obligations related to our metallurgical coal procurement contracts, which are generally based on annual coke production requirements at fixed coal prices, were $928.6 million and extend through 2024. As of December 31, 2023, significant contractual obligations related to debt were $500 million of principal borrowings and $134.1 million of related interest, which will be repaid through 2029. See Note 11 to our consolidated financial statements. We also have contractual obligations for leases, including land, office space, equipment, railcars and locomotives. See Note 13 to our consolidated financial statements.

Capital Requirements and Expenditures

Our operations are capital intensive, requiring significant investment to upgrade or enhance existing operations and to meet environmental and operational regulations. The level of future capital expenditures will depend on various factors, including market conditions and customer requirements, and may differ from current or anticipated levels. Material changes in capital expenditure levels may impact financial results, including but not limited to the amount of depreciation, interest expense and repair and maintenance expense.

Our capital requirements have consisted, and are expected to consist, primarily of:

• Ongoing capital expenditures required to maintain equipment reliability, the integrity and safety of our coke ovens and steam generators and to comply with environmental regulations. Ongoing capital expenditures are made to replace partially or fully depreciated assets in order to maintain the existing operating capacity of the assets and/or to extend their useful lives and also include new equipment that improves the efficiency, reliability or effectiveness of existing assets. Ongoing capital expenditures do not include normal repairs and maintenance expenses, which are expensed as incurred;
• Expansion capital expenditures to acquire and/or construct complementary assets to grow our business and to expand existing facilities as well as capital expenditures made to enable the renewal of a coke sales agreement and/or logistics service agreement and on which we expect to earn a reasonable return; and
• Environmental remediation project expenditures required to implement design changes to ensure that our existing facilities operate in accordance with existing environmental permits.

The following table summarizes our capital expenditures:

Critical Accounting Policies and Estimates

A summary of our significant accounting policies is included in Note 2 to our consolidated financial statements. Our management believes that the application of these policies on a consistent basis enables us to provide the users of our financial statements with useful and reliable information about our operating results and financial condition. The preparation of our consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and the disclosures of contingent assets and liabilities. The Company's black lung benefit obligations is an item that is subject to such estimates and assumptions. Although our management bases its estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, actual results may differ to some extent from the estimates on which our consolidated financial statements have been prepared at any point in time. Despite these inherent limitations, our management believes the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and consolidated financial statements and footnotes provide a meaningful and fair perspective of our financial condition.

Black Lung Benefit Liabilities

The Company has obligations related to coal workers’ pneumoconiosis, or black lung, to provide benefits to certain of its former coal miners and their dependents further described in Note 12 to our consolidated financial statements.

We adjust our liability each year based upon actuarial calculations of our expected future payments for these benefits. Our independent actuarial consultants calculate the present value of the estimated black lung liability annually based on actuarial models utilizing our population of former coal miners, historical payout patterns of both the Company and the industry, actuarial mortality rates, medical costs, death benefits, dependents, discount rates and the current federally mandated payout rates. The estimated liability may be impacted by future changes in the statutory mechanisms, modifications by court decisions and changes in filing patterns by claimants and their advisors, the impact of which cannot be estimated.

The following table summarizes discount rates utilized, active claims and the total black lung liabilities. Our independent actuarial consultants calculate the present value of the black lung liability annually in the fourth quarter, unless there are changes in facts and circumstances that could materially alter the amount of the liability.

(Dollars in millions)

(1) The discount rate is determined based on a portfolio of high-quality corporate bonds with maturities that are consistent with the estimated duration of our black lung obligations. A decrease of 25 basis points in the discount rate would have increased black lung expense by $1.4 million in 2023.

(2) The current portion of the black lung liability was $5.0 million and $5.9 million at December 31, 2023 and 2022, respectively, and was included in accrued liabilities on the Consolidated Balance Sheets.

The following table summarizes the annual black lung payments and expense (benefit):

(Dollars in millions)

(1) Black lung expense (benefit) incurred in excess of annual accretion of the black lung liability reflects the impact of changes in discount rates, current filing and approval rate assumptions and/or other changes in our actuarial assumptions.

Recent Accounting Standards

See Note 2 to our consolidated financial statements.

Our primary areas of market risk include the following: (1) changes in the price of coal and coke in certain cases, as detailed below; (2) changes in interest rates; and (3) changes in foreign currency exchange rates. We do not enter into any market risk sensitive instruments for trading purposes.

Price of coal and coke

Although we have not previously done so, we may enter into derivative financial instruments from time to time in the future to economically manage our exposure related to these market risks.

Coal is the key raw material for our cokemaking business and is the largest component of the cost of our coke. Under our long-term, take-or-pay coke sales agreements at our Domestic Coke cokemaking facilities, coal costs are a pass-through component of the coke price, provided that we are able to realize certain targeted coal-to-coke yields. As such, when targeted coal-to-coke yields are achieved, the price of coal is not a significant determining factor in the profitability of coke sold under our long-term, take-or-pay agreements, which comprise the vast majority of our sales volumes in our Domestic Coke segment.

Our long-term, take-or-pay agreements require us to meet minimum production levels and generally require us to provide replacement coke if we do not meet contractual minimum volumes. To the extent any of our facilities are unable to produce their contractual minimum volumes, and we are unable to supply coke from one of our other facilities, we are subject to market risk related to the procurement of replacement supplies.

We are subject to market risk for the price of coals used to produce non-contracted blast coke sold into both the export and North American domestic coke markets. Non-contracted blast coke sales are typically based on coke market pricing at the time of sale, rather than the pass-through provisions in our long-term, take-or-pay agreements. Generally over time, market prices for metallurgical coal and coke have been correlated. We monitor the market for our coal purchases versus pricing in the coke markets to optimize profitability in both the export and North American domestic coke markets. However, we are exposed to market risk to the extent the coal and coke markets fall out of correlation. Additionally, the timing of contracting our coal purchases versus the timing of contracting our coke sales may cause favorable or unfavorable differences between the prices at which we procure our coals and the market rates at which we are able to sell our coke into both the export and North American domestic coke markets. We are also subject to market risk for the price of coal as it relates to the foundry coke sales. However, our foundry coke prices are largely set at the time we negotiate our coal purchases and therefore we are less exposed to market risk as it relates to the volatility in the price of coal on our foundry coke sales.

Interest rates

We are exposed to changes in interest rates as a result of borrowing activities with variable interest rates and interest earned on our cash balances. During the years ended December 31, 2023 and 2022, the daily average outstanding balance on borrowings with variable interest rates was $14.9 million and $105.8 million, respectively. Assuming a 50 basis point change in secured overnight financing rate (“SOFR”), interest expense would have been impacted by $0.1 million and $0.5 million in 2023 and 2022, respectively. At December 31, 2023, we had no outstanding borrowings with variable interest rates under the Revolving Facility.

At December 31, 2023 and 2022, we had cash and cash equivalents of $140.1 million and $90.0 million, respectively, which accrue interest at various rates. Assuming a 50 basis point change in the rate of interest associated with our cash and cash equivalents, interest income would have been impacted by $0.6 million and $0.4 million for the years ended December 31, 2023 and 2022, respectively.

Foreign currency

Because we operate outside the U.S., we are subject to risk resulting from changes in the Brazilian real currency exchange rates. The currency exchange rates are influenced by a variety of economic factors including local inflation, growth, interest rates and governmental actions, as well as other factors. Revenues and expenses of our foreign operations are translated at average exchange rates during the period and balance sheet accounts are translated at period-end exchange rates. Balance sheet translation adjustments are excluded from the results of operations and are recorded in equity as a component of accumulated other comprehensive loss. If the currency exchange rates had changed by 10 percent, we estimate the impact to our net income in 2023 and 2022 would have been approximately $0.4 million in both periods.

Management’s Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, is responsible for evaluating the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)). Our disclosure controls and procedures are designed to provide reasonable assurance that the information required to be disclosed by us in reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure and is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered by this report, our disclosure controls and procedures were effective at the reasonable assurance level.

Management’s Report on Internal Control over Financial Reporting

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, is responsible for establishing and maintaining adequate internal control over our financial reporting, as such term is defined under Exchange Act Rule 13a-15(f). Our internal control system was designed to provide reasonable assurance to management regarding the preparation and fair presentation of published financial statements.

In evaluating the effectiveness of our internal control over financial reporting as of December 31, 2023, management used the framework set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control-Integrated Framework (2013). Based on such evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2023.

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal controls over financial reporting will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues, misstatements, errors, and instances of fraud, if any, within our company have been or will be prevented or detected. These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Controls also can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Projections of any evaluation of controls effectiveness to future periods are subject to risks that internal controls may become inadequate as a result of changes in conditions, or through the deterioration of the degree of compliance with policies or procedures.

Our independent registered public accounting firm, KPMG LLP, has audited the Company's consolidated financial statements included in this Annual Report on Form 10-K and, as part of its audit, has issued an attestation report on our internal control over financial reporting, which is contained in Item 8, “Financial Statements and Supplementary Data.”

Changes in Internal Control over Financial Reporting

There was no change in the Company’s internal control over financial reporting that occurred during the quarter ended December 31, 2023 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
