Steel Industry Background and Competition

The global steel industry is cyclical, highly competitive and has historically been characterized by global overcapacity.

U. S. Steel's competitive position may be affected by, among other things, differences among U. S. Steel's and its competitors' cost structure, labor costs, environmental remediation and compliance costs, global capacity, achievement of innovations in new technologies and sustainable products and the existence and magnitude of government support.

U. S. Steel competes with many North American and international steel producers. Competitors include 1) integrated producers, which use iron ore and coke as the primary raw materials for steel production, 2) Electric Arc Furnace (EAF) producers, which primarily use steel scrap and other iron-bearing feedstocks as raw materials and 3) slab re-rollers, who purchase mostly imported, but some domestic, semi-finished products and convert them into sheet products. In addition, other materials, such as aluminum, plastics and composites, compete with steel in several applications. According to worldsteel Association, global steel production in 2022 declined compared to 2021, decreasing by 4 percent, or approximately 80 million metric tons, to 1.88 billion metric tons. Steel production generally decreased across the world, with the global decline primarily being driven by the top five steel producing countries and Ukraine, which collectively represents approximately 60 percent of the total global decline. Among the top five steel producing countries, production decreased in China by 22 million metric tons, or 2 percent; Japan by 7 million metric tons, or 7 percent; the U.S. by 5 million metric tons, or 6 percent; and Russia by 6 million metric tons, or 7 percent. These declines were partially offset however by India, which increased crude steel production by 7 million metric tons, or 5 percent, from 2021. Steel production in Ukraine decreased by 15 million metric tons, or 71 percent, from 2021 as a result of the Russian invasion and the impact of the ongoing conflict. The top five steel producing countries accounted for 73 percent of the world's steel production in 2022.

See "International Trade" below for a discussion of global overcapacity and the Company's efforts to mitigate the competitive impact.

EAF producers typically require lower capital expenditures for construction and operation of facilities and may have lower total employment costs. Some EAF producers utilize thin slab casting technology to produce flat-rolled products and are increasingly able to compete directly with integrated producers in many flat-rolled product applications previously produced only by integrated steelmakers. Slab re-rollers do not incur the cost of melting steel; their input costs are largely driven by the market price of slabs.

U. S. Steel provides defined benefit pension and/or other post-employment benefits to approximately 65,000 current employees, retirees and their beneficiaries. Many of our competitors do not have comparable retiree obligations. Participation in U. S. Steel's main defined benefit pension plan was closed to new entrants on July 1, 2003 and benefit accruals for all non-represented participants were frozen effective December 31, 2015. Participation in U. S. Steel’s retiree medical and life insurance programs for United Steelworkers (USW)-represented employees were closed to employees hired or rehired (except in limited circumstances) on or after January 1, 2016. For non-represented employees, retiree medical benefits were eliminated December 31, 2017, and retiree life insurance benefits for non-represented employees were eliminated for those who retired after December 31, 2017.

We believe that our major North American and many European integrated steel competitors are confronted with substantially similar environmental regulatory conditions and therefore do not believe that our relative position with regard to such competitors will be materially affected by the impact of environmental laws and regulations. However, if future regulations do not recognize that the integrated steel process involves a series of chemical reactions involving carbon that create carbon dioxide (CO2) emissions without linking these emissions to steel scrap as well, the competitive position of our integrated operations will be adversely impacted compared to mini mills. Our competitive position compared to producers in developing nations such as China, Russia, Brazil and India will be harmed unless such nations require commensurate reductions in CO2 emissions or there are policies to adjust for the carbon emissions disparities. Competing materials such as plastics may not be similarly impacted. The specific impact on each competitor will vary depending on a number of factors, including the age and location of its operating facilities and its production methods. U. S. Steel is also responsible for remediation costs related to former and present operating locations and disposal of environmentally sensitive materials. Many of our competitors, including North American producers, or their successors, that have been the subject of bankruptcy relief have no or substantially lower liabilities for such environmental remediation matters.

In 2023, we expect additional steelmaking capacity will enter the domestic steel market as competitors' growth projects come on-line or ramp up to full production in North America throughout the year.

Business Strategy

We are executing on our customer-centric Best for All® strategy to provide customers with profitable steel solutions for people and planet. Our strategy is focused on developing quality products and customer process solutions by investing where we have distinct cost or capability competitive advantages. We are expanding our competitive advantages in low-cost iron ore, mini mill steelmaking, and best-in-class finishing assets with innovative solutions and commercial acumen. These competitive advantages are built on a foundation of research, innovation and deep customer relationships. In executing our strategy, we aim to enhance our earnings profile, deliver long-term cash flow through industry cycles and reduce our cost, capital, and carbon intensity. By offering the product capabilities, including the more sustainable steels (steels made with lower greenhouse gas emissions) our customers are increasingly demanding, we can achieve more competitive positioning in strategic, high-margin end markets, and deliver high-quality, sustainable, value-added products and innovative solutions.

Our strategy is informed by our critical success factors, which are the bedrock of the Best for All® strategy: (1) Win in Strategic Markets; (2) Move Up the Talent Curve; and (3) Move Down the Cost Curve. We are enhancing our competitive advantage in low-cost iron ore by expanding this advantage to serve our growing fleet of EAF producers (EAFs). We are currently investing in pig iron capability to enhance the efficiencies of our blast furnace operations as well as reduce the cost structure and reduce the global supply chain risk of our EAFs by increasingly feeding them with internally-produced pig iron. In the future, we may plan to further expand our low-cost iron ore advantage by incorporating in direct reduced iron (DRI) or hot briquetted iron (HBI) capabilities into our internal supply chain. We recently took an important step in this direction by investing in direct reduced (DR)-grade pellet capabilities to produce the feedstock for a potential future investment in DRI/HBI. We are also investing in new technologies to improve our cost position and increase our capabilities, including our mini mill steelmaking and best-in-class finishing capabilities. We will focus on strategic markets, where there is the greatest opportunity to provide differentiated, innovative and value-added solutions that will help our customers succeed. We know that to accomplish our objectives, we also need to continue to move up the talent curve. We are investing in our employees and providing the training and resources they need to succeed. This will help us reinforce a culture of caring, where accountability, fairness and respect are foundational, and high performance and inclusion in all its forms are valued and celebrated. See "Human Capital Management" below for additional information on our talent attraction, development, and retention initiatives.

U. S. Steel will continue to evaluate potential strategic and organizational opportunities, which may include the acquisition, divestiture or consolidation of assets. Given the cyclicality of our industry, we are focused on strategically deploying our capital, in-line with our capital allocation framework, in order to invest in areas consistent with the execution of our Best for All strategy and are considering various possibilities, including exiting lines of business and the sale of certain assets, that we believe would ultimately result in greater stockholder value. The Company will pursue opportunities based on its long-term strategy that is aligned with what is in the best interests of the Company's stockholders.

Strategic Projects, Technology Investments and Operating Configuration Adjustments

Throughout 2022, the Company continued to advance its Best for All strategy. On January 11, 2022, the Company announced Osceola, Arkansas as the site of a new sustainable and technologically advanced steel mill. The planned mini mill is expected to have about 3 million tons per year of steelmaking capability, and will combine two state-of-the-art EAFs with differentiated steelmaking and finishing technology, including endless casting and rolling equipment and a planned advanced high-strength steel (AHSS) finishing line. The Company is working with the same technical advisors and engineers who were instrumental in the successful construction of the adjacent Big River Steel facilities. Upon completion, we expect that this project will apply to become LEED® certified. We believe that the continued adoption of mini mill technology will expand our ability to produce the next generation of proprietary sustainable steel solutions, including AHSS. The project is expected to be completed in 2024.

In the second quarter 2022, the Company began the construction of a pig iron caster at our Gary Works facility. The approximately $60 million capital investment will produce up to 500,000 tons of pig iron annually and provide a critical raw material input for the Company's EAFs. The Gary Works pig iron project is expected to provide nearly 50 percent of Big River Steel’s ore-based metallics needs and deliver an internal rate of return in excess of 30 percent. Pig iron production at Gary Works and shipments to Big River Steel began in the fourth quarter 2022.

In the third quarter 2022, the Company began construction of a DR grade pellet facility at its Keetac ore operations. The approximately $150 million investment is expected to be operational in 2024. In addition to producing DR-grade pellets to ultimately feed EAFs with DRI or HBI, the production facility will maintain flexibility to continue producing blast furnace grade pellets. Upon completion, the Company could also sell the DR-grade pellets to third-party DRI or HBI producers. The DR-grade pellets produced will be a new product line for U. S. Steel.

In August 2021, the Company commenced construction on a non-grain oriented (NGO) electrical steel line at Big River Steel. The Company expects this $450 million investment to make Big River Steel a leader in NGO electrical steels by delivering product capabilities in this growing market. The 200 thousand ton NGO electrical steel line is expected to deliver first coil in September 2023 and be available to meet the growing electric vehicle demand expected in North America over the coming years.

In the third quarter 2021, the Company also began construction on a 325 thousand ton galvanize/Galvalume® line at Big River Steel. This $280 million investment is expected to grow the Company’s best-in-class finishing capabilities, by expanding the

Company’s presence in value-added construction applications and enhancing Big River Steel’s product mix. This finishing line is expected to begin production in second quarter 2024.

As the Company advances and expands its mini mill capability, it seeks to become better, not bigger and will adjust its footprint accordingly by re-evaluating cost and capability advantages within its evolving footprint. In December 2021 and June 2022, the Company permanently idled the steelmaking and ironmaking operations, respectively, at its Great Lakes Works facility. In addition, in March 2022, the Company permanently idled the finishing facilities at its East Chicago Tin operations, which had been idled on an indefinite basis during 2019. The coil finishing process at Great Lakes Works continues to operate and remains a component of the Company's operating plans. In December 2022, we the Company indefinitely idled the majority of tin operations at our Gary Works facility.

Commercial Strategy

Our commercial strategy is focused on providing customer-centric solutions with differentiated and value-added steel products, which includes advanced high strength steels such as our newer grades of generation 3 (GEN3) steel, coated sheets for the automotive and appliance industries, electrical steel sheets for the manufacture of motors and electrical equipment, both bare and prepainted galvanized and Galvalume® sheets for construction, heavy gauge hot rolled coils used in the production of construction and agricultural-related heavy machinery as well as skelp for line pipe used for energy transmission as well as extraction, tin mill products for the packaging industry and OCTG pipe, connections, accessories and rig site services for use in drilling for oil and gas. In addition, our portfolio of customers serves a variety of different traditional and emerging industries meeting the needs of numerous markets.

U. S. Steel is committed to leveraging our Best for All strategy to develop and commercialize our low-carbon footprint and advanced high-strength steels for our current and future customers. Over the next five years, U. S. Steel plans to develop and commercialize numerous differentiated grades of low-carbon footprint, high rate of recycled-content steels, providing compelling new options for customers in automotive, appliance, industrial equipment, construction, renewable energy and other markets to enhance the sustainability of their products. For example, in April 2021, we announced a new sustainable steel product line, verdeXTM, which is made with up to 90% recycled steel content and a reduced carbon footprint - as much as 70-80% smaller than traditional integrated steelmaking methods. After launching our verdeXTM brand of sustainable steel products in 2021, we worked closely with customers on their own sustainability goals. In 2022, we reached agreements with multiple customers on the sale of verdeXTM products moving forward in industries such as automotive, construction, and distribution, setting the stage for increased sales of verdeXTM in these and other industries in 2023 and beyond. In addition, we continue to work with customers in numerous industries to help them implement AHSS solutions in the products they manufacture. While the automotive industry has been most active in the application of these products in new vehicle platforms, and it continues to accelerate the deployment of AHSS solutions in new vehicle launches, U. S. Steel is successfully introducing AHSS in other industries as well. Our collaboration with Greenbrier and Norfolk-Southern generated new AHSS sales into the railcar market in 2022, and we also commenced new projects in other industries such as appliance, construction, and in the renewable energy sector to create stronger, lightweight, cost-effective AHSS applications.

We are responsive to our customers' changing needs by developing new steel products and uses for steel that meet their evolving markets and regulatory demands. We have research centers in Munhall, Pennsylvania, Košice, Slovakia, and Houston, Texas, as well as a technology center in Troy, Michigan. The focus of these centers is to engineer new products and to co-create innovative solutions that meet our customers' toughest challenges to reduce carbon emissions, increase strength, improve longevity and serve the needs of their customers. In the fourth quarter 2022, we continued to invest in our talent by hiring a Chief Technology Officer to provide overall enterprise leadership, focusing on driving innovation and product development, as well as enhancing our manufacturing capability.

For automotive customers leveraging advanced high strength steels, we commissioned a first of its kind GEN3 hot dipped galvanize line at our PRO-TEC Coating Company (PRO-TEC) joint venture in 2020, and have embedded application engineers at original equipment manufacturers (OEMs) to demonstrate how to best utilize the high strength, highly formable, cost effective material in body design to meet passenger safety requirements while significantly reducing weight to meet future vehicle fuel efficiency standards.

In our tubular markets, we continue development of premium and semi-premium tubular connections designed for our customers that operate in challenging drilling environments. These connections optimize well construction activities and provide outstanding sealing capabilities for onshore and offshore oil and gas drilling in North America. An example is the USS-TALON HTQ™, which was introduced in 2020 for customers that are constructing onshore natural gas and oil wells with long laterals requiring best-in-class torque capacity and optimized well-bore clearances.

Commercial Sales of Product

U. S. Steel characterizes sales as contract sales if sold pursuant to an agreement with a defined volume and pricing and a duration of longer than three months, and as spot if sold without a defined volume and pricing agreement, typically three months or less. In 2022, approximately 76 percent, 61 percent, 48 percent and 78 percent of sales by Flat-Rolled, Mini Mill, USSE and Tubular, respectively, were contract sales. Some contract pricing agreements include fixed prices while others are adjusted periodically based upon published prices of steel products or cost components.

Ethics & Compliance

Our culture is based on our S.T.E.E.L. Principles: Safety First; Trust and Respect; Environmental Stewardship; Excellence and Accountability; and Lawful and Ethical Conduct. We expect our employees and members of our board of directors to take personal responsibility to “do what’s right,” and our Code of Ethical Business Conduct serves as the foundation for the actions of our employees and directors. To further ensure that employees understand the Company’s expectations and all applicable rules, we provide annual formal ethics and compliance training to our employees and have frequent communications with information about key compliance topics, which include messages from senior management underscoring the importance of doing business with integrity. Employees also receive summaries of current events that demonstrate the need to do business lawfully and ethically that include reminders of the company’s expectations for all employees. In addition, through our annual policy certification process, employees of USSK, non-represented employees in the United States, and members of our board of directors certify their ongoing compliance with our Code of Ethical Business Conduct.

Employee Health & Safety

At U. S. Steel, we have a long-standing commitment to the safety and health of every person who works in our facilities. Every employee deserves to return home safely at the end of every day, and we are working to eliminate all injuries and incidents. In addition, the psychological safety of all employees is important to us. We have combined physical safety and psychological safety into the construct of 360° safety. Ensuring a safe workplace also improves productivity, quality, reliability and financial performance. By making safety and health a personal responsibility, our employees are making a daily commitment to follow safe work practices, look out for the safety of co-workers and ensure safe working conditions for everyone. A “Safety First” mindset is as essential to our success as the tools and technologies we rely on to do business.

Our objective is to attain a sustainable zero harm culture supported by leadership and owned by an engaged and highly skilled workforce, empowered with the capabilities and resources needed to assess, reduce and eliminate workplace risks and hazards. In support of these objectives, we have developed an enhanced Safety Management System, initiated new safety communication methods and enhanced contractor safety processes. One of our most important safety protocols is our fatality prevention audit program. These proactive assessments of the processes and protocols we have in place, and adherence to them, to avoid fatalities and severe injuries are conducted annually at the enterprise level and more frequently at each of our facilities. We assess our safety performance through a variety of lagging and leading indicators, including OSHA Days Away From Work (DAFW). This measurement allows us to evaluate the frequency of injuries sustained at our facilities requiring an employee to stay at home for more than one day. U. S. Steel has achieved record-safety performance in this measurement in the last several years, routinely achieving performance better than industry benchmarks.

Table of Contents

For 2022, we had a corporate DAFW rate of 0.05, which is 18 times better than the U.S. Bureau of Labor Statistics' Iron and Steel benchmark DAFW rate of 0.90.

Diversity, Equity, & Inclusion

Attracting, developing, and retaining a workforce of talented, diverse people is essential to having high-performing teams that drive results for our Company’s stakeholders. As part of our commitment to cultivating a culture of caring, we have inclusive benefits available for our U.S. non-represented workforce, including expanded parental leave, back-up dependent care, infertility coverage, gender reassignment coverage and healthcare continuation for the families of employees who suffered work-related or military service fatalities. We also support several employee resource groups (ERGs) to enhance employee engagement, promote a culture of belonging, foster diversity in the workplace, and raise awareness related to issues of identity and intersectionality. Our ERGs also provide training and education, mentorship and networking opportunities for their members.

Talent Attraction, Development and Retention

We believe that attraction, development and retention of talent is essential to our success, especially in today’s competitive labor market. We offer internship programs, partner with universities, community colleges and technical schools, and collaborate with community employment centers and economic development nonprofit organizations to build strong and diverse internal and external sources of potential employees and opportunities for our existing employee's growth and development.

Once at U. S. Steel, we seek to provide opportunities for continuous learning and development. All of our employees at a director-level and above have a formal professional development plan that is assessed at least annually. In addition, we proactively monitor our attrition rates and take targeted actions to ensure our highest potential and performing employees are motivated to remain with the Company. Over the past five years, our regrettable voluntary turnover rate has been at or below 5 percent.

We offer a competitive total rewards package of compensation and benefits that we regularly evaluate and benchmark across the manufacturing industry to ensure that we position U. S. Steel as an employer of choice.

At the onset of the pandemic in early 2020, we quickly transitioned our corporate and administrative employees, approximately 10% of our workforce, to a work-from-home environment. We’ve invested in technology to maintain this virtual community and found that our employees are more productive and have more flexibility and autonomy in managing their workload in a way that best fits their situation. We plan to maintain a virtual / hybrid working option for these employees in order to promote workplace flexibility and attract and retain highly qualified employees across the country.

Labor Relations

Approximately 80% of our employees in North America and Slovakia are covered by collective bargaining agreements. We work closely with union representatives to provide safe and productive workplaces that enable our employees to deliver high-quality products and meet the needs of our customers. Our relationship with the United Steelworkers (USW) includes not only a

Table of Contents

commitment to safety programs, but also a common approach to combating the unfairly traded imports that threaten our industry, our company and ultimately the jobs of our employees.

Certain hourly employees of U. S. Steel’s flat-rolled, tubular, cokemaking and iron ore operations in the United States are covered by collective bargaining agreements with the USW entered into effective September 1, 2022, (the 2022 Labor Agreements) that expire on September 1, 2026. The 2022 Labor Agreements include a signing bonus for each eligible USW-represented employee and annual 5% wage increases effective September 1, 2022, 2023, 2024 and 2025. The 2022 Labor Agreements also provide for certain increases to pension and retirement benefits, including increases in our defined benefit pension plan, retiree healthcare contributions, and to the contribution rate to the Steelworkers Pension Trust from $3.50 to $4.00 per hour, effective January 1, 2023. During the fourth quarter of 2022, U. S. Steel recorded a charge of approximately $67 million for the 2022 Labor Agreements signing bonus and related costs.

In addition, as part of the collective bargaining process, U. S. Steel and the USW agreed to leverage the overfunded OPEB plans to support the benefits provided to active represented employees. The OPEB plans were modified to allow the Company to utilize a certain amount of surplus assets to pay additional legally permissible benefits previously paid by the Company. The arrangement permits the Company to utilize a target of $75 million annually for active and retiree employee benefits, with an annual minimum of $50 million, beginning in 2023 and continuing through December 31, 2026. For additional information, see Note 18 to the Consolidated Financial Statements in Part II Item 8 of this Form 10-K.

Capital Structure, Liquidity and Capital Allocation

Our Best for All strategy's primary financial goal is to enhance stockholder value by utilizing our capital structure, liquidity and enhanced capital allocation priorities to advance the Company's strategic objectives, generate long-term value and reward stockholders. Our cash deployment strategy is aligned with our corporate strategy and includes: executing on strategic projects and portfolio moves; maintaining a strong balance sheet and a healthy pension plan; and delivering sustainable growth with a focus on core values such as safety and environmental stewardship and rewarding stockholders for the continued progress we make. Cash deployment is also performed with a customer-centric focus on improving safety, our environment, quality, delivery and cost.

Our liquidity supports our ability to satisfy short-term obligations, fund working capital requirements and provides a foundation to execute key strategic priorities. We are focused on maintaining a strong balance sheet and may proactively refinance or repay our debt from time to time to protect our capital structure from unforeseen external events and re-financing risks.

On May 27, 2022, U. S. Steel entered into the Sixth Amended and Restated Credit Facility Agreement (Credit Facility Agreement) to replace the existing Fifth Amended and Restated Credit Facility Agreement (Fifth Credit Facility Agreement). The Credit Facility Agreement has substantially the same terms as the Fifth Credit Facility Agreement, except the Credit Facility Agreement references the Secured Overnight Financing Rate instead of the London Interbank Offered Rate, adjusts the individual lenders' commitments, and renews the five-year maturity to May 27, 2027, and the financial impact from replacing the Fifth Credit Facility Agreement was immaterial. The Credit Facility Agreement also adjusts the threshold for the fixed charge coverage ratio. The total availability under the facility remained the same at $1,750 million. Consistent with the Fifth Credit Facility Agreement, the Credit Facility Agreement is secured by first-priority liens on certain accounts receivable and inventory and includes targets related to greenhouse gas emissions intensity reduction, safety performance and facility certification by ResponsibleSteel™.

On September 6, 2022, U. S. Steel closed on an offering of $290 million aggregate principal amount of 5.450% Environmental Improvement Revenue Bonds due 2052 (2052 ADFA Green Bonds). U. S. Steel received net proceeds of approximately $287 million after fees of approximately $3 million related to the underwriting and third-party expenses. The net proceeds from the issuance of the 2052 ADFA Green Bonds will be used to partially fund work related to U. S. Steel's solid waste disposal facilities, including two EAFs and other equipment facilities at its new technologically-advanced flat rolled steel making facility, BR2, currently under construction near Osceola, Arkansas.

In 2022, we repurchased approximately $365 million in debt, and we ended the year with $5.9 billion of total liquidity.

On July 25, 2022, following the completion of previously authorized $800 million share repurchase programs, the Board of Directors authorized a new share repurchase program for the repurchase of up to $500 million of the Company's outstanding common stock from time to time in the open market or privately negotiated transactions at the discretion of management. The Company's share repurchase program does not obligate it to acquire any specific number of shares.

U. S. Steel repurchased 37.6 million shares of common stock for approximately $849 million under these programs during the year ended December 31, 2022, and there is approximately $301 million remaining under the current stock repurchase authorization. In addition, the Board of Directors declared quarterly dividends of five cents per common share for each of the quarters in 2022.

Raw Materials and Energy

As a predominantly integrated producer, U. S. Steel’s primary raw materials are iron units in the form of iron ore pellets and sinter ore, carbon units in the form of coal and coke (which is produced from coking coal) and steel scrap. For our EAF production, our primary raw material is scrap. U. S. Steel’s raw materials supply strategy consists of acquiring and expanding captive sources of certain primary raw materials and entering into flexible supply contracts for certain other raw materials at competitive market prices that are subject to fluctuations based on market conditions at the time.

The amounts of such raw materials needed to produce a ton of steel will fluctuate based upon the specifications of the final steel products, the quality of raw materials and, to a lesser extent, differences among steel producing equipment. In broad terms, the Company's integrated steel process consumes approximately 1.4 tons of coal to produce one ton of coke and then it consumes approximately 0.3 tons of coke, 0.3 tons of steel scrap (approximately 60 percent of which is internally generated) and 1.3 tons of iron ore pellets to produce one ton of raw steel. In addition, we consume approximately 10 mmbtu’s of natural gas per ton produced. Generally, the Company's mini mill operations consumes approximately 0.8 tons of steel scrap, 0.3 tons of pig iron, and 0.1 tons of HBI to produce one ton of raw steel. In addition, the mini mill operations consume approximately 0.6 MKWH of electricity per ton of raw steel produced. While we believe that these estimated consumption amounts are useful for planning purposes, and are presented to give a general sense of raw material and energy consumption related to steel production, substantial variations may occur.

Iron Ore

(a) Includes our share of production from Hibbing through December 31, 2022.

The iron ore facilities at Minntac and Keetac contain approximately 900 million short tons of indicated resources and probable reserves and our share of recoverable reserves at the Hibbing joint venture is approximately 4 million short tons. Refer to Mining Properties in Item 2 of this Form 10-K for additional information. Recoverable reserves are defined as the tons of product that can be used internally or delivered to a customer after considering mining and beneficiation or preparation losses. Minntac and Keetac’s annual capability and our share of annual capability for the Hibbing joint venture total approximately 23 million tons. We have iron ore pellet production capability that exceeds our steelmaking capability in the U.S.

We historically have sold iron ore pellets to third parties, including in 2022, 2021 and 2020. The Company has agreements to supply iron ore pellets to third-party customers over the next several years.

Substantially all of USSE’s iron ore requirements are purchased from outside sources, primarily Ukrainian and Brazilian mining companies. Prices are determined in long-term contracts with strategic suppliers or as spot prices negotiated monthly or quarterly. USSE also has received iron ore from U. S. Steel’s iron ore facilities in North America. We believe that supplies of iron ore adequate to meet USSE’s needs are available at competitive market prices.

Coking Coal

All of U. S. Steel’s coal requirements for our cokemaking facilities are purchased from outside sources. Pricing for Flat-Rolled's coking coal contracts are typically negotiated on a yearly basis, and from time to time we have entered into multi-year agreements for a portion of our coking coal requirements.

Prices for European contracts are negotiated quarterly, annually or determined as index-based prices.

Table of Contents

We believe that supplies of coking coal adequate to meet our needs are available from outside sources at competitive market prices. The main source of coking coal for Flat-Rolled is the United States, and sources for USSE include Poland, Ukraine, Canada, Australia and the United States.

Coke

In North America, the Flat-Rolled segment operates a cokemaking facility at the Clairton Plant of Mon Valley Works. At our Granite City Works, we have a 15-year coke supply agreement with Gateway that expires on December 31, 2024. Blast furnace injection of coal, and self-generated coke oven gas is also used to reduce coke usage.

With Flat-Rolled’s cokemaking facilities and the Gateway long-term supply agreement, it has the capability to be nearly self-sufficient with respect to its annual coke requirements at normal operating levels. Coke from time to time has been purchased from, sold to, or swapped with suppliers and other end-users to adjust for production needs and reduce transportation costs.

In Europe, the USSE segment operates cokemaking facilities at USSK. While USSE is self-sufficient for coke at normal operating levels, it periodically purchases coke from Polish and Czech coke producers to meet production needs. Volume and price are negotiated quarterly.

Steel Scrap and Other Materials

We believe that supplies of steel scrap and alloys that are adequate to meet our needs are readily available from outside sources at competitive market prices for the Flat-Rolled, Mini Mill and USSE segments. Generally, approximately 38 percent of our steel scrap requirements were internally generated through normal operations for these segments.

Limestone

All of Flat-Rolled’s limestone requirements and USSE's lime and limestone requirements are purchased from outside sources. We believe that supplies of limestone and lime adequate to meet our needs are readily available from outside sources at competitive market prices.

Zinc and Tin

We believe that supplies of zinc and tin required to fulfill the requirements for Flat-Rolled, Mini Mill and USSE are available from outside sources at competitive market prices. For Flat-Rolled and Mini Mill the main sources of zinc are Canada, Mexico and the United States and the main sources of tin are Bolivia, Brazil and Peru. For USSE, the main sources of zinc are Finland, Poland, the Netherlands, Germany and Slovakia and the main sources of tin are Peru, Indonesia, China and Bolivia.

During 2022, Flat-Rolled protected approximately 40 percent and 75 percent of its operation's zinc and tin purchases, respectively, with financial swap derivatives to manage exposure to zinc and tin price fluctuations. During 2022, USSE protected approximately 16 percent of its operation's zinc purchases with forward physical contracts to manage our exposure to zinc price fluctuations and protected approximately 68 percent of its operation's tin purchases with financial swaps to manage our exposure to tin price fluctuations. For further information, see Note 16 to the Consolidated Financial Statements.

Natural Gas

All of U. S. Steel’s natural gas requirements are purchased from outside sources.

Table of Contents

We believe that adequate supplies to meet Flat-Rolled’s, Mini Mill's and Tubular's needs are available at competitive market prices. For 2022, approximately 70 percent of our natural gas purchases in Flat-Rolled were based on bids solicited on a monthly basis from various vendors; the remainder were made daily or with term agreements.

We believe that adequate natural gas supplies to meet USSE’s needs are available at competitive market prices. During 2022, we routinely executed fixed-price forward physical purchase contracts for natural gas to partially manage our exposure to natural gas price increases. For 2022, approximately 48 percent of our natural gas purchases in USSE were made with fixed-price forward physical purchase contracts; the remainder were based on bids solicited on a quarterly or monthly basis.

Flat-Rolled and USSE use self-generated coke oven and blast furnace gas to reduce consumption of natural gas. USSE uses self-generated coke oven, converter and blast furnace gas to reduce consumption of natural gas and steam coal that results in lower CO2 emissions production.

Additionally, Russian supply of natural gas to Europe has decreased significantly in response to enacted sanctions. However, Slovakia has natural gas storage and access to additional supply from countries including Norway, the U.S. and Africa. Together, these sources are enough to support the country's expected consumption through the 2023 winter season, which includes demand for natural gas for our USSE segment operations.

Industrial Gases

U. S. Steel purchases industrial gas in the U.S. under long-term contracts with various suppliers. USSE owns and operates its own industrial gas facility, but also may purchase industrial gases from time to time from third parties.

International Trade

U. S. Steel continues to face import competition, much of which is unfairly traded and fueled by massive global steel overcapacity, currently estimated to be over 500 million metric tons per year—more than five times the entire U.S. steel market and over seventeen times total U.S. steel imports. These imports and overcapacity negatively impact the Company’s operational and financial performance. U. S. Steel continues to lead efforts to address these challenges that threaten the Company, our workers, our stockholders and our country’s national and economic security.

The U.S. Department of Commerce (DOC) is managing a process in which U.S. companies may request and/or oppose temporary product exclusions from the Section 232 tariffs and quotas. U. S. Steel opposes exclusion requests for imported products that are the same as, or substitutes for, products manufactured by U. S. Steel.

Multiple legal challenges to the Section 232 action continue before the U.S. Court of International Trade (CIT) and the U.S. Court of Appeals for the Federal Circuit (CAFC), the latter which has consistently rejected constitutional and statutory challenges to the Section 232 action.

Since its implementation in March 2018, the Section 232 action has supported the U.S. steel industry’s and U. S. Steel’s investments in advanced steel production capabilities, technology and skills, strengthening U.S. national and economic security. The Company continues to actively defend the Section 232 action.

In February 2019, the European Commission (EC) implemented a definitive safeguard on global steel imports in the form of TRQs that impose 25 percent tariffs on steel imports that exceed the TRQ limit, effective through June 2024. In December 2022, the EC initiated a fourth review of the safeguard.

Antidumping duties (AD) and countervailing duties (CVD or antisubsidy duties) apply in addition to the Section 232 tariffs, quotas, TRQs and the EC’s safeguard, and AD/CVD orders may continue beyond the Section 232 action and the EC’s safeguard. U. S. Steel continues to actively defend and maintain the 61 U.S. AD/CVD orders and 14 EU AD/CVD orders covering U. S. Steel products in multiple proceedings before the DOC, U.S. International Trade Commission (ITC), CIT, CAFC, the EC and European courts, and the World Trade Organization (WTO).

In July 2022, the ITC voted to continue the AD/CVD orders on corrosion-resistant steel from China, India, Italy, South Korea and Taiwan and cold-rolled steel from China, India, Japan, South Korea and the UK for another five years, but voted to revoke the AD/CVD orders on cold-rolled steel from Brazil. In October 2022, the ITC voted to continue the AD/CVD orders on hot-rolled

Table of Contents

steel from Australia, Japan, Korea, Netherlands, Russia, Turkey and the United Kingdom for another five years, but voted to revoke the AD/CVD orders on hot-rolled steel from Brazil. Also, in October 2022, the ITC voted to impose new AD/CVD orders on imports of OCTG from Argentina, Mexico, Korea and Russia.

In August 2022, the EC imposed definitive AD measures on imports of hot-dipped galvanized steel from Russia and Turkey and announced the continuation of AD measures on imports of cold-rolled steel from China and Russia for another five years. The EC is conducting five-year reviews of the AD/CVD orders on hot-rolled steel from five countries with a decision expected in 2023.

In April 2022, the U.S. suspended normal trade relations with Russia and Belarus, resulting in higher than normal tariffs on imports from Russia and Belarus, including steel and raw materials. In June, President Biden announced additional tariff increases on certain products from Russia, including certain steel products and ferroalloys, effective August 1, 2022.

Additional tariffs of 7.5 to 25 percent continue to apply to certain U.S. imports from China, including certain raw materials used in steel production, semi-finished and finished steel products, and downstream steel-intensive products, pursuant to Section 301 of the Trade Act of 1974. The Office of the United States Trade Representative (USTR) is currently conducting a statutory review of the Section 301 tariffs.

The United States and EU are currently negotiating a global sustainable steel arrangement to restore market-oriented conditions and address carbon intensity that is targeted for completion by the end of 2023.

U. S. Steel will continue to execute a broad, global strategy to maximize opportunities and navigate challenges presented by imports, global steel overcapacity, and international trade law and policy developments.

Environmental Stewardship

U. S. Steel is committed to effective environmental stewardship. We have implemented and continue to develop business practices that are designed to reduce negative environmental impacts. We believe part of being a good corporate citizen requires a dedicated focus on how our industry affects the environment. We have taken the actions described below in furtherance of that goal. U. S. Steel's environmental expenditures totaled $334 million in 2022, $302 million in 2021 and $278 million in 2020. Overall, environmental compliance expenditures represent approximately 2 percent of U. S. Steel’s total costs and expenses in 2022, 2021 and 2020. For further information, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Environmental Matters.”

We continue to work on the promotion of cost-effective environmental strategies by supporting the development of appropriate air, water and waste laws and regulations at the local, state, national and international levels. We are committed to reducing our emissions and are investigating, creating and implementing innovative, best practice solutions throughout our operations to improve our environmental performance and to manage and reduce energy consumption.

U. S. Steel’s North America operations recycled 4.8 million tons of purchased and produced steel scrap annually in 2022 and in 2021. USSK recycled approximately 754 thousand tons and 970 thousand tons of produced steel scrap in 2022 and 2021, respectively. Because of steel’s physical properties, our products can be recycled at the end of their useful life without loss of quality, contributing to steel’s high recycling rate and affordability. North America operations recycled approximately 2.2 million tons of blast furnace slag, 58 thousand tons of Basic Oxygen Process steel slag, and 75 thousand tons of electric arc furnace slag by selling it for use as aggregate and in highway construction. In 2022, USSK recycled approximately 1.1 million tons of blast furnace slag, and 168 thousand tons of Basic Oxygen Process steel slag.

Many of our major production facilities have Environmental Management Systems that are certified to the ISO 14001 Standard. This standard, published by the International Organization for Standardization (ISO), provides the framework for the measurement and improvement of environmental impacts of the certified facility.

In 2019, and in each succeeding year since, we published the Clairton Operating and Environmental Report related to our Clairton Plant of Mon Valley Works. While U. S. Steel agreed to publish an annual report as part of the 2019 Allegheny County Health Department Settlement Order and Agreement, we took the opportunity to enhance the report by including detailed descriptions of our operations, our safety and environmental performance and community involvement in order to provide easily accessible information for the public. The Report details battery combustion stack and fugitive emission performance at Clairton and Clairton's continued commitment to environmental stewardship. In 2021, we published a similar report for the Edgar Thomson facility.

Reduction of Greenhouse Gas Emissions

In 2019, the Company announced its commitment to reduce greenhouse gas emissions intensity across its global footprint by 20 percent, as measured by the rate of CO2 equivalents emitted per ton of finished steel shipped, by 2030 based on 2018 baseline levels. Then, in 2021, the Company announced its goal to achieve net-zero emissions by 2050, as measured by the rate of CO2

Table of Contents

equivalents emitted per ton of finished steel shipped. The Company has provided information on paths to achieve this goal on its website. These targets apply to U. S. Steel’s global operations.

U. S. Steel plans to achieve its greenhouse gas emissions intensity reduction goals through the execution of multiple initiatives. These include the use of EAF steelmaking technology at U. S. Steel’s Fairfield Works and at Big River Steel, the first LEED-certified steel mill in the United States and the first steel mill in North America to receive ResponsibleSteel™ site certification. EAF steelmaking primarily relies on recycled scrap, rather than iron ore, to produce new steel products, which is a less carbon intensive process and leverages the ability to continuously recycle steel. Further carbon intensity reductions are expected to come from the implementation of ongoing energy efficiency measures, continued use of renewable energy sources and other process improvements to be developed.

The carbon reduction targets reflect our continued commitment to improvement in production efficiency and the manufacture of products that are environmentally friendly. In addition to a commitment to reduce its own greenhouse gas emissions intensity, U. S. Steel is committed to helping its customers achieve their environmental goals. Our industry-leading XG3™ advanced high-strength steel enables automakers to manufacture lighter weight vehicles that meet federal Corporate Average Fuel Economy (CAFE) standards with reduced carbon emissions. As part of our innovation efforts, we continue to look at new steelmaking technologies so that we can produce green steels and further reduce carbon emissions.

Environmental Matters, Litigation and Contingencies

Some of U. S. Steel’s facilities were in operation before 1900. Although the Company believes that its environmental practices have either led the industry or at least been consistent with prevailing industry practices, hazardous materials have been and may continue to be released at current or former operating sites or delivered to sites operated by third parties.

Our U.S. facilities are subject to environmental laws applicable in the U.S., including the Clean Air Act (CAA), the Clean Water Act (CWA), the Resource Conservation and Recovery Act (RCRA) and the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), as well as state and local laws and regulations.

U. S. Steel has incurred and will continue to incur substantial capital, operating and maintenance and remediation expenditures as a result of environmental laws and regulations, related to release of hazardous materials, which in recent years have been mainly for process changes to meet CAA obligations and similar obligations in Europe.

EU Environmental Requirements and Slovak Operations

Phase IV of the EU Emissions Trading System (EU ETS) commenced on January 1, 2021, and will finish on December 31, 2030. The European Commission issued final approval of the updated 2021-2025 Slovak National Allocation table in February 2022. Subsequently, the Slovak Ministry of Environment allocated the full amount of 2022 free allowances totaling 6.3 million European Union Emission Allowances (EUA) to USSE in February and April 2022. As of December 31, 2022, we have pre-purchased approximately 2.1 million EUA totaling €147 million (approximately $157 million) to cover the expected 2022 and 2023 shortfall of emission allowances.

The EU's Industrial Emissions Directive requires implementation of EU determined best available techniques (BAT) for Iron and Steel production to reduce environmental impacts as well as compliance with BAT associated emission levels. Total capital expenditures for projects to comply with or go beyond BAT requirements were €138 million (approximately $147 million). These costs were partially offset by the EU funding received and may be mitigated over the next measurement periods if USSK complies with certain financial covenants, which are assessed annually. USSK complied with these covenants as of December 31, 2022. If we are unable to meet these covenants in the future, USSK might be required to provide additional collateral (e.g., bank guarantee) to secure 50 percent of the EU funding received.

For further discussion of laws applicable in Slovakia and the EU and their impact on USSE, see Note 26 to the Consolidated Financial Statements, “Contingencies and Commitments, Environmental Matters, EU Environmental Requirements.”

Minnesota Mining Operations - Water

The State of Minnesota has a sulfate wild rice water quality standard (WQS) set at 10mg/L. This sulfate WQS was established in 1973, since this time industry has been working with the legislature and the Minnesota Pollution Control Agency (MPCA) to reevaluate the environmental protection and science behind the 10 mg/L standard. In 2011, the legislature passed a law requiring MPCA to revise the sulfate standard. MPCA started the process to revise the rulemaking for the sulfate WQS, but it was never completed. During the interim the Keetac National Pollutant Discharge Elimination System (NPDES) permit was issued in November 2011 with a sulfate standard of 14 mg/L and a compliance schedule. Then in 2015, the Minnesota legislature passed a law that MPCA could not require businesses to expend funds to comply with the sulfate limit until the rulemaking was revised by MPCA as directed by the legislature in 2011. To date the sulfate WQS rulemaking has not been revised. During this time Minntac has also received a NPDES permit with a sulfate limit and compliance schedule.

Both Minntac and Keetac have been working to determine the best options to address sulfate. One of the options in process is that both sites have submitted and even renewed site-specific standard (SSS) requests to MPCA. The SSS present plans specific to each location and explain the actual impact on sulfate from the facilities. To date MPCA has not taken any action on

Table of Contents

the SSS plans. The United States Environmental Protection Agency (the U.S. EPA) partially rejected the CWA 303(d) list for impaired waters submitted by MPCA for 2021. The MPCA's impaired waters list was in part rejected to add Hay Lake as being impaired for wild rice sulfate. In February 2022, the U.S. EPA Region V sent a letter to MPCA recognizing the conflict between state law and the CWA.

U. S. Steel is continuing to work to determine the most efficient and effective options to meet the sulfate standard. However, if MPCA does not revise the sulfate standard of 10mg/L or approve the SSS it is likely to have an impact on mining operations as it will require extensive changes to water collection and treatment.

New and Emerging Environmental Regulations

United States and European Greenhouse Gas Emissions Regulations

The Phase IV EU ETS period spans 2021-2030 and began on January 1, 2021.The Phase IV period is divided into two sub periods (2021-2025 and 2026-2030), rules for the first subperiod are finalized, however we expect that rules for the second subperiod may be more stringent than those for the first one. Once approved, the rules may impact subperiod 2026-2030. Currently, the overall EU ETS target is a 40 percent reduction of 1990 emissions by 2030. Free allocation of CO2 allowances is based on reduced benchmark values which have been published in the first quarter of 2021 and historical levels of production from 2014-2018. Allocations to individual installations may be adjusted annually to reflect relevant increases and decreases in production. The threshold for adjustments is set at 15 percent and will be assessed on the basis of a rolling average of two precedent years. Production data verified by an external auditor shows that USSE rolling average for 2020-2021 returned to base limit for hot metal production resulting in increase of the free allocation for 2022 compared to 2021, however 2022 free allocation was still slightly reduced due to missing the 15 percent threshold for sinter production. Additionally, lower production in 2019 through 2021 will have an impact on the future free allocation for 2026-2030, where the historical production average for years 2019-2023 will be assessed. Based on actual production data for 2022, we expect that free allocation for hot metal will remain unchanged for 2023, however allocations for sinter will be lower.

In order to achieve the EU political goal of carbon emissions neutrality by 2050, on July 14, 2021, the European Commission released a package of legislative proposals called Fit for 55. The proposals contain significant changes to current EU ETS functions and requirements, including: a new carbon border adjustment mechanism to impose carbon fees on EU imports, further reduction of free CO2 allowance allocation to heavy industry and measures to strengthen the supply of carbon allowances. The legislative process is being impacted by the ongoing Russia-Ukraine crisis. The proposals are subject to the EU legislative process, and we cannot predict their future impact.

United States - Air

The CAA imposes stringent limits on air emissions with a federally mandated operating permit program and civil and criminal enforcement sanctions. The CAA requires, among other things, the regulation of hazardous air pollutants through the development and promulgation of National Emission Standards for Hazardous Air Pollutants (NESHAP) and Maximum Achievable Control Technology (MACT) Standards. The U.S. EPA has developed various industry-specific MACT standards pursuant to this requirement. The CAA requires the U.S. EPA to promulgate regulations establishing emission standards for each category of Hazardous Air Pollutants. The U.S. EPA also must conduct risk assessments on each source category that is already subject to MACT standards and determine if additional standards are needed to reduce residual risks.

While our operations are subject to several different categories of NESHAP and MACT standards, the principal impact of these standards on U. S. Steel's operations includes those that are specific to coke making, iron making, steel making and iron ore processing.

On July 13, 2020, the U.S. EPA published a Residual Risk and Technology Review rule for the Integrated Iron and Steel MACT category in the Federal Register. Based on the results of the U.S. EPA’s risk review, the agency determined that risks due to emissions of air toxics from the Integrated Iron and Steel category are acceptable and that the current regulations provided an ample margin of safety to protect public health. Under the technology review, the U.S. EPA determined that there are no developments in practices, processes or control technologies that necessitate revision of the standards. In September 2020, several petitions for review of the rule, including those filed by the Company, the American Iron and Steel Institute (the AISI), Clean Air Council and others, were filed with the United States Court of Appeals for the D.C. Circuit. The cases were consolidated and are being held in abeyance until the U.S. EPA reviews and responds to administrative petitions for review. The U.S. EPA is required by court order to issue a final rule by October 26, 2023. Because the U.S. EPA has yet to propose a revised iron and steel rule, any impacts are not estimable at this time.

For the Taconite Iron Ore Processing category, based on the results of the U.S. EPA's risk review, the agency promulgated a final rule on July 28, 2020, in which the U.S. EPA determined that risks from emissions of air toxics from this source category are acceptable and that the existing standards provide an ample margin of safety. Furthermore, under the technology review, the agency identified no cost-effective developments in controls, practices, or processes to achieve further emissions reductions. Petitions for review of the rule were filed in the United States Court of Appeals for the D.C. Circuit, in which the Company and the

Table of Contents

AISI intervened. The U.S. EPA is required by court order to issue a final rule by November 16, 2023. Because the U.S. EPA has yet to propose a revised taconite rule, any impacts are not estimable at this time.

The U.S. EPA is in the process of conducting its statutorily obligated residual risk and technology review of coke oven standards. Because the U.S. EPA has not completed its review of the Coke MACT regulations, any impacts related to the U.S. EPA’s review of the coke standards cannot be estimated at this time. The U.S. EPA is under a court-ordered deadline to complete the residual risk and technology rulemaking by May 23, 2024.

In response to Court orders that invalidated prior U.S. EPA determinations regarding ozone attainment interference, on April 6, 2022, the U.S. EPA proposed a Federal Implementation Plan (that would replace several pending or disapproved State Implementation Plans) for Regional Ozone Transport for the 2015 Ozone National Ambient Air Quality Standard. The proposed rule would affect electric generating units (EGUs) in 26 states and certain non-EGU industries, including, among several others, coke ovens, taconite production kilns, boilers, blast furnaces, basic oxygen furnaces, reheating furnaces, and annealing furnaces in 23 states, including those where U. S. Steel has operations. The impacts of the rule, if promulgated as proposed, could be material. U. S. Steel submitted comments on the proposed rule on June 21, 2022. Based upon the U.S. EPA agreements with non-governmental organizations the rule is likely to be published as final by the U.S. EPA during the first quarter 2023. Once the rule is final, U. S. Steel will further evaluate the potential impacts to operations.

The CAA also requires the U.S. EPA to develop and implement National Ambient Air Quality Standards (NAAQS) for criteria pollutants, which include, among others, particulate matter (PM) - consisting of PM10 and PM2.5, lead, carbon monoxide, nitrogen dioxide, sulfur dioxide (SO2) and ozone.

In October 2015, the U.S. EPA lowered the NAAQS for ozone from 75 parts per billion (ppb) to 70 ppb. On November 6, 2017, the U.S. EPA designated most areas in which we operate as attainment with the 2015 standard. In a separate ruling, on June 4, 2018, the U.S. EPA designated other areas in which we operate as “marginal nonattainment” with the 2015 ozone standard. On December 6, 2018, the U.S. EPA published a final rule regarding implementation of the 2015 ozone standard. Because no state regulatory or permitting actions to bring the ozone nonattainment areas into attainment have yet to be proposed or developed for U. S. Steel facilities, the operational and financial impact of the ozone NAAQS cannot be reasonably estimated at this time. On December 31, 2020, the U.S. EPA published a final rule pursuant to its statutorily required review of NAAQS that retains the ozone NAAQS at 70 ppb. In January 2021, New York, along with several states and non-governmental organizations filed petitions for judicial review of the action with the United States Court of Appeals for the D.C. Circuit. Several other states and industry trade groups intervened in support of the U. S. EPA’s action. The case remains in abeyance before the court until December 15, 2023, as the U.S. EPA voluntarily reconsiders the ozone NAAQS. Because the U.S. EPA has yet to complete its reconsideration and propose a revised ozone NAAQS, any impacts are not estimable at this time.

On December 18, 2020, the U.S. EPA published a final rule pursuant to its statutorily required review of NAAQS that retains the existing PM2.5 standards without revision. In early 2021, several states and non-governmental organizations filed petitions for judicial review of the action with the United States Court of Appeals for the D.C. Circuit. Several industry trade groups intervened in support of the U.S. EPA’s action. The case remains in abeyance before the court until March 1, 2023, as the U.S. EPA voluntarily reconsiders the PM2.5 NAAQS. On January 6, 2023, the U.S. EPA proposed to lower the annual PM2.5 NAAQS from the current 12 ug/m3 standard to within the range of 9.0 to 10.0 ug/m3. U. S. Steel is currently reviewing the proposal to determine the impacts and evaluate any need to comment. Because the U.S. EPA has very recently proposed the rule without specificity, any impacts are inestimable at this time.

For calendar year 2022, all Allegheny County ambient air quality monitors met all U.S. EPA health based National Ambient Air Quality Standards for the second consecutive year. On March 16, 2022, the U.S. EPA published a final rule, a clean data determination, showing that Allegheny County has attained the 2012 annual PM2.5 NAAQS based on the 2018 – 2020 ambient air quality data. Based on these and other data, ACHD submitted a Redesignation Request and Maintenance Plan to the U.S. EPA requesting that the U.S. EPA redesignate all of Allegheny County in attainment with the current PM2.5 NAAQS.

United States – Water

The U.S. EPA issued the final rule redefining the Waters of the United States (WOTUS), set to become effective March 1, 2023. The definition of WOTUS has had many changes and legal challenges over the last several years. The new WOTUS rule expands the definition of what all waters will be considered to be a waters of the United States. The expansion of the WOTUS definition is likely to lead to additional legal challenges. It is also possible that the ruling in the U. S. Supreme court case Sackett v. EPA would impact the WOTUS definition as it relates to wetlands. The Sackett case was heard by the Court in the Fall 2022 term and decision is expected early in 2023. U. S. Steel will continue to review the final WOTUS definition and its potential impact on the Company.

Item 1A. RISK FACTORS

Economic and Market Risk Factors

The changing global economic climate is having adverse impacts on our business, which may create new risks and exacerbate certain other risks set forth below.

Changes in the global economic environment, inflation, rising interest rates, recessions or prolonged periods of slow economic growth, and global instability and actual and threatened geopolitical conflict, could have an adverse effect on our industry and business, as well as those of our customers and suppliers.

Overall economic conditions in the U.S. and globally, including in Europe, including adverse factors such as inflation, rising interest rates, supply chain disruptions and the impacts of the war in Ukraine, significantly impact our business. Periods of economic downturn or continued uncertainty could result in difficulty increasing or maintaining our level of sales or profitability and we may experience an adverse effect on our business, results of operations, financial condition and cash flows.

Our U.S. operations are subject to economic conditions, including credit and capital market conditions, inflation, prevailing interest rates, and political factors, which if changed could negatively affect our results of operations, cash flows and liquidity. Political factors include, but are not limited to, changes to tax laws and regulations resulting in increased income tax liability, increased regulation, such as carbon emissions limitations or trading mechanisms, limitations on exports of energy and raw materials, and trade remedies. Actions taken by the U.S. government could affect our results of operations, cash flows and liquidity.

USSE is subject to economic conditions and political factors associated with the EU, Slovakia and neighboring countries, and the euro currency. Changes in any of these economic conditions or political factors could negatively affect our results of operations, cash flows and liquidity. Political factors include, but are not limited to, taxation, nationalization, inflation, government instability, regional conflict, civil unrest, increased regulation and quotas, tariffs, sanctions and other market-distorting measures. The ongoing war in Ukraine has had a broad range of adverse impacts on global economic conditions, some of which have had and are likely to continue to have adverse impacts on our business, including increased raw material and energy costs, softer

Table of Contents

customer demand and lower steel prices. USSE purchases a significant portion of its iron ore and coal from suppliers based in Ukraine.

Additionally, we are also exposed to risks associated with the business success and creditworthiness of our suppliers and customers. If our customers or suppliers are negatively impacted by a slowdown in economic markets, we may face the reduction, delay or cancellation of customer orders, delays or interruptions of the supply of raw materials, and increased risk of insolvency and other credit related issues of customers or suppliers, which could delay payments from customers, result in increased customer defaults and cause our suppliers to delay filling, or to be unable to fill, our needs at all or on a timely or cost-effective basis. The occurrence of any of these events may adversely affect our business, results of operations, financial condition and cash flows.

The steel industry, as well as the industries of our customers and suppliers upon whom we are reliant, is highly cyclical, which may have an adverse effect on our customer demand and results of operations.

Steel consumption is highly cyclical and generally follows economic and industrial conditions both worldwide and in regional markets. Price fluctuations are impacted by the timing, magnitude and duration of these cycles, and are difficult to predict. This volatility makes it difficult to balance the procurement of raw materials and energy with global steel prices, our steel production and customer product demand. U. S. Steel has implemented strategic initiatives to produce more stable and consistent results, even during periods of economic and market downturns, but this may not be enough to mitigate the effect that the volatility inherent in the steel industry has on our results of operations.

Additionally, our business is reliant on certain other industries that are cyclical in nature. We sell to the automotive, service center, converter, energy and appliance and construction-related industries. Some of these industries are highly sensitive to general economic conditions and may also face meaningful fluctuations in demand based on a number of factors outside of our control, including regulatory factors, supply chain disruptions, changing customer demand, economic conditions and raw material and energy costs. As a result, downturns or volatility in any of the markets we serve could adversely affect our financial position, results of operations and cash flows.

U. S. Steel has been and continues to be adversely affected by unfairly traded imports and global overcapacity, which may cause downward pricing pressure, lost sales and revenue, market share, decreased production, investment, and profitability.

Currently, global steel production capacity significantly exceeds global steel demand, which adversely affects U.S. and global steel prices. Global overcapacity continues to result in high levels of dumped and subsidized steel imports into the markets we serve. Domestic and international trade laws provide mechanisms to address the injury caused by such imports to domestic industries. Excessive steel imports have resulted and may continue to result in downward pricing pressure and lost sales and revenue, which adversely impacts our business, operations, financial condition and cash flows.

Although U. S. Steel currently benefits from 61 U.S. AD and CVD or anti-subsidy duty orders and 14 EU AD/CVD orders, petitions for trade relief are not always successful or effective. When implemented, such relief is generally subject to periodic reviews and challenges, which can result in revocation of AD/CVD orders or reduction of effective duty rates. There can be no assurance that any relief will be obtained or continued in the future or that such relief will adequately combat unfairly traded imports.

As of the date of this filing, pursuant to a series of Presidential Proclamations issued in accordance with Section 232 of the Trade Expansion Act of 1962, U.S. imports of certain steel products are subject to a 25 percent tariff, except imports from: (1) Argentina, Brazil, and South Korea, which are subject to restrictive quotas; (2) the EU, Japan, and UK that are melted and poured in the EU/Japan/UK, within quarterly TRQ limits; (3) Canada and Mexico, which are not subject to tariffs or quotas, but tariffs could be re-imposed on surging product groups after consultations; (4) Ukraine, which are exempt from tariffs until June 1, 2023; and (5) Australia, which are not subject to tariffs, quotas, or an anti-surge mechanism. The Section 232 national security action on steel imports currently provides U. S. Steel and other domestic steel producers critical relief from imports. With no scheduled end date, the future coverage and duration of the Section 232 action is not known. Further, the U.S. government may negotiate alternatives to the Section 232 tariffs for certain countries, similar to TRQ agreements with the EU, Japan, and the UK.

USTR's review of additional imports tariffs of 7.5 to 25 percent on certain U.S. imports from China, including certain raw materials used in steel production, semi-finished and finished steel products, and downstream steel-intensive products, pursuant to Section 301 of the Trade Act of 1974 could change the coverage and levels of such tariffs.

In February 2019, the EC implemented a definitive safeguard on global steel imports in the form of TRQs. The TRQs, which impose 25 percent tariffs on steel imports that exceed the TRQ limit, are currently effective through June 2024. In December 2022, the EC initiated its fourth periodic review of this safeguard, which may result in adjustments to the safeguard TRQ limits.

All of the above factors present a degree of uncertainty to our financial and operational performance, our customers, and overall economic conditions, all of which could impact steel demand and our performance. Faced with significant import competition and

Table of Contents

overcapacity in various markets, we will continue to evaluate potential strategic and organizational opportunities, which may include exiting lines of business and the sale of certain assets, temporary shutdowns or closures of facilities.

Shortages of skilled labor, increased labor costs or our failure to attract and retain other highly qualified personnel in the future could disrupt our operations and adversely affect our financial results.

We depend on skilled labor for the manufacture of our products. Some of our facilities are located in areas where demand for skilled labor often exceeds supply. Shortages of some types of skilled labor, such as electricians and qualified maintenance technicians, could restrict our ability to maintain or increase production rates, lead to production inefficiencies and increase our labor costs. Our shift to the Best for All strategy will also require a set of job skills that is different from our prior needs. Our continued success depends on the active participation of our key employees. We have recently observed an overall tightening and increasingly competitive labor market. The competitive nature of the labor markets in which we operate, the cyclical nature of the steel industry and our resulting needs for skilled employees increase our risk of not being able to recruit, train and retain the employees we require at efficient costs and on reasonable terms, and could lead to increased costs, such as increased overtime to meet demand and increased wage rates to attract and retain employees. In addition, many companies, including U. S. Steel, have had employee layoffs as a result of reduced business activities during industry downturns. The loss of our key people or our inability to attract new key employees could adversely affect our operations. Additionally, layoffs or other adverse actions could result in an adverse relationship with our workforce or third-party labor providers. If we are unable to recruit, train and retain adequate numbers of qualified employees and third-party labor providers on a timely basis or at a reasonable cost or on reasonable terms, our business and results of operations could be adversely affected. Additionally, an overall labor shortage, lack of skilled labor, increased turnover or labor inflation as a result of general macroeconomic factors that affect our customers or suppliers could have a material adverse impact on the company’s operations, results of operations, liquidity or cash flows.

Strategic Risk Factors

Our investments in new technologies and products may not be fully successful.

Execution of our Best for All® strategy depends, in part, on the success of a number of investments we have made and plan to make in new facilities, technologies and products and successfully transitioning our footprint to a lower-cost, carbon and capital intensive model. Our Best for All strategy is centered around expanding our competitive advantages in low-cost iron ore mini mill steelmaking, and best-in-class finishing capabilities. These competitive advantages are built on a foundation of research, innovation and deep customer relationships. We are expanding our low-cost iron ore competitive advantage by investing in ways to translate the advantage to feed our growing EAF footprint. This includes investments in a pig iron caster at the Gary Works facility and DR-grade pellet capabilities in Keetac, Minnesota. We are expanding our mini mill steelmaking capabilities through the construction of a second mini mill facility in Osceola, Arkansas. We are also expanding our best-in-class finishing capabilities through investments in a non-grain oriented electrical steel line and galvanizing construction line at Big River Steel. In executing our strategy, we aim to enhance our earnings profile, deliver long-term cash flow through industry cycles and reduce our cost, capital, and carbon intensity. By offering the product capabilities, including the more sustainable steels (steels made with lower greenhouse gas emissions) our customers are increasingly demanding, we believe that we can achieve more competitive positioning in strategic, high-margin end markets, and deliver high-quality, sustainable, value-added products and innovative solutions.

Construction of our strategic projects is subject to changing market conditions and demand for our completed projects, delays, inflation and cost overruns, work stoppages, labor shortages, engineering issues, weather interferences, supply chain delays, changes required by governmental authorities, delays or the inability to acquire required permits or licenses, changes in the ability to finance the projects or disruption of existing operations, any of which could have an adverse impact on our operational and financial results. Furthermore, new product development or modification is costly, may be restricted by regulatory requirements, involves significant research, development, time, expense and human capital and may not necessarily result in the successful commercialization of new products, customer adoption of new technologies or products or new technologies may not perform as intended or expected. Unsuccessful execution of these strategic projects, underperformance of any of these assets or failure of new products to gain market acceptance could adversely affect our business, results of operations and financial condition and may limit the benefits of our stockholder value creation strategy.

From time to time, we engage in acquisitions, divestitures and joint ventures and may encounter difficulties in integrating and separating these businesses and therefore we may not realize the anticipated benefits.

As we pursue our Best for All® strategy, we may seek growth opportunities through strategic acquisitions as well as evaluate our portfolio for potential divestitures to optimize our business footprint and portfolio. The success of these transactions will depend on our ability to integrate or separate, as applicable, assets and personnel in these transactions and to cooperate with our strategic partners. We may encounter difficulties in integrating acquisitions with our operations as well as separating divested businesses, and in managing strategic investments. Furthermore, we may not realize the degree, or timing, of benefits we anticipate when we first enter into a transaction.

Additionally, we seek opportunities to monetize non-core and excess iron assets, including through real estate sales, third party agreements and option agreements. These opportunities may not materialize or generate the financial benefits expected. For

Table of Contents

example, Stelco Inc. holds an option (Option) to acquire an undivided 25 percent interest in a to-be-formed entity that will own the Company’s current iron ore mine located in Mt. Iron, Minnesota. There is a possibility that Stelco may not exercise its Option in the anticipated timeframe or at all. If the proposed joint venture with Stelco is not successful, fails to provide the benefits we expect, or is not created at all, we may in the future have more iron ore than we need to support the business. Additionally, the existence of the Option may deter future potential opportunities to monetize the iron ore assets. Any of the foregoing could adversely affect our business and results of operations.

Operational and Commercial Risk Factors

Our operational footprint, unplanned equipment outages and other unforeseen disruptions may adversely impact our results of operations or result in idle facility costs or impairment charges.

U. S. Steel has adjusted its operating configuration to advance its Best for All® strategy, in response to market conditions, including global economic volatility, declining steel prices, oil and gas industry disruption, global overcapacity and unfairly traded imports, and to optimize capability and cost performance, by idling and restarting production at certain facilities. Due to our existing operational footprint, the Company may not be able to respond in an efficient manner to fully realize the benefits from changing market conditions that are favorable to integrated steel producers or most efficiently mitigate the negative impacts of such changes. Our decisions concerning which facilities to operate and at what levels are made based upon execution of our Best for All strategy, market conditions, our customers’ orders for products as well as the capabilities and cost performance of our locations. We may concentrate production operations at several plant locations and not operate others, and as a result we may incur idle facility costs or impairment charges.

Our steel production depends on the operation of critical structures and pieces of equipment, such as blast furnaces, electric arc furnaces, steel shops, casters, hot strip mills and various structures and operations, including information technology systems, that support them, as well as finishing lines at our facilities and certain of our joint ventures. While we invested in operational and reliability enhancements to our assets through the asset revitalization program, launched in 2017, and continue to implement initiatives focused on proactive maintenance of key machinery and equipment at our production facilities, we may experience prolonged periods of reduced production and increased maintenance and repair costs due to equipment failures at our facilities or those of our key suppliers.

It is also possible that operations may be disrupted due to other unforeseen circumstances such as power outages, explosions, fires, floods, pandemics, terrorism, accidents, severe weather conditions, and changes in U.S., European Union and other foreign tariffs, free trade agreements, trade regulations, laws and policies. We are also exposed to similar risks involving major customers and suppliers such as force majeure events of raw materials suppliers that have occurred and may occur in the future. Availability of raw materials and delivery of products to customers could be affected by logistical disruptions, such as shortages of barges, ocean vessels, rail cars or trucks or unavailability of rail lines or of the locks on the Great Lakes or other bodies of water. To the extent that lost production could not be compensated for at unaffected facilities and depending on the length of the outage, our sales and our unit production costs could be adversely affected.

We are subject to risks related to the global COVID-19 pandemic, which has had adverse impacts on economic and market conditions and our business. COVID-19 has created significant volatility, uncertainty and economic disruption in the regions in which we operate. We expect that certain parts of our operations will continue to be impacted by the continuing effects of COVID-19, including resurgences and variants of the virus. It remains difficult to predict the full impact of the COVID-19 pandemic on the broader economy, and whether such change is temporary or permanent.

The physical impacts of climate change may also have a material adverse effect on our results of operations. Climate change may be associated with increased occurrence of extreme weather conditions, which could include, among other things, increased risk of flooding, potential heat stress at facilities and other natural disasters that may lead our customers to curtail or shut down production or to supply chain and operational disruptions.

We face increased competition within our industry and from alternative materials and risks concerning innovation, new technologies, products and increasing customer demand for lower-carbon products.

As a result of increasingly stringent regulatory requirements and increased market and technological changes driven by broader trends such as decarbonization and electrification efforts in response to climate change, designers, engineers and industrial manufacturers, especially those in the automotive industry, are increasing their use of lighter weight, less carbon intense and alternative materials, such as aluminum, composites, plastics and carbon fiber. Use of such materials could reduce the demand for our steel products or steel products generally, which may reduce our profitability and cash flow. Additionally, the trend toward light weighting in the automotive industry, which requires lighter gauges of steel at higher strengths, could result in lower steel volumes required by that industry over time.

Additionally, technologies such as direct iron reduction, oxygen-coal injection and experimental technologies such as molten oxide electrolysis and hydrogen flash smelting may be more cost effective than our current production methods. However, we may not have sufficient capital to invest in such technologies and may incur difficulties adapting and fully integrating these

Table of Contents

technologies into our existing operations. We may also encounter production restrictions, or not realize the cost benefit from such capital intensive technology adaptations to our current production processes.

Limited availability, or volatility in prices of raw materials, scrap and energy may constrain operating levels and reduce profit margins.

U. S. Steel and other steel producers have periodically faced problems obtaining sufficient raw materials and energy in a timely manner due to delays, defaults, severe weather conditions, or force majeure events, shortages or transportation problems (such as shortages of barges, ore vessels, rail cars or trucks, or disruption of rail lines, waterways, or natural gas transmission lines), resulting in production curtailments. As a result, we may be exposed to risks concerning pricing and availability of raw materials and energy resources from third parties as well as logistics constraints moving our own raw materials and scrap to our plants. USSE purchases substantially all of its iron ore and coking coal requirements from outside sources. Any curtailments or escalated costs may further reduce profit margins.

U. S. Steel has agreed, and may continue to agree, to purchase raw materials and energy at prices that have been, and may be, above future market prices or in greater volumes than required in the future. Additionally, any future decreases in iron ore, scrap, natural gas, electricity and oil prices may place downward pressure on steel prices. If steel prices decline, our profit margins on indexed contracts and spot business could be reduced.

A failure of our information technology infrastructure and cybersecurity threats may adversely affect our business operations.

Despite efforts to protect confidential business information, personal data of employees and contractors, and the control systems of manufacturing plants, U. S. Steel systems and those of our third-party service providers have been and may be subject to cyber-attacks or system breaches. System breaches can lead to theft, unauthorized disclosure, modification or destruction of proprietary business data, personally identifiable information (PII), or other sensitive information, to defective products, production downtime and damage to production assets, and the inaccessibility of key systems, with a resulting impact to our reputation, competitiveness and operations. We have experienced cybersecurity attacks that have resulted in unauthorized persons gaining access to our information technology systems and networks, and we could in the future experience similar attacks. To date, no cybersecurity attack has had a material impact on our financial condition, results of operations or liquidity.

While the Company continually works to safeguard our systems and mitigate potential risks, there can be no assurance that such actions will be sufficient to prevent cyber-attacks or security breaches or mitigate all potential risks to our systems, networks and data, particularly with the recent proliferation and sophistication of ransomware attacks around the world. The potential consequences of a material cybersecurity attack include reputational damage, investigations and/or adverse proceedings with government regulators or enforcement agencies, litigation with third parties, disruption to our systems, including production capabilities, unauthorized release of confidential, personally identifiable or otherwise protected information, corruption of data, diminution in the value of our investment in research, development and engineering and increased cybersecurity protection and remediation costs, which in turn could adversely affect our competitiveness, results of operations and financial condition. The amount of insurance coverage we maintain may be inadequate to cover claims or liabilities resulting from a cybersecurity attack.

We depend on third parties for transportation services and increases in costs or the availability of transportation may adversely affect our business and operations.

Our business depends on the transportation of a large number of products, both domestically and internationally. We rely primarily on third parties, including the recently divested Transtar business, for transportation of the products we manufacture as well as delivery of our raw materials. Any increase in the cost of the transportation of our raw materials or products, as a result of increases in fuel or labor costs, higher demand for logistics services, consolidation in the transportation industry or otherwise, may adversely affect our results of operations as we may not be able to pass such cost increases on to our customers.

Our transportation service providers may face disruptions due to weather conditions or events, strikes, labor shortages or other constraints. If any of these providers were to fail to deliver raw materials to us or deliver our products in a timely manner, we may be unable to manufacture and deliver our products in response to customer demand. In addition, if any of these third parties were to cease operations or cease doing business with us, we may be unable to replace them at a reasonable cost. Such failure of a third-party transportation provider could harm our reputation, negatively affect our customer relationships and have a material adverse effect on our financial position and results of operations.

Our 2022 Labor Agreements with the USW contain provisions that may impact certain business activities.

Our 2022 Labor Agreements with the USW contain provisions that grant the USW a limited right to bid on the Company’s sale of a facility (or sale of a controlling interest in an entity owning a facility) covered by the 2022 Labor Agreements, excluding public equity offerings and/or the transfer of assets between U. S. Steel and its wholly owned subsidiaries. These agreements also require a minimum level of capital expenditures (subject to approval of the Board of Directors) to maintain the competitive status

Table of Contents

of the covered facilities, and place certain limited restrictions on our ability to replace product produced at a covered facility with product produced at other than Company facilities or affiliates or U.S. or Canadian facilities with employee protections similar to the protections found in the 2022 Labor Agreements when the Company is operating covered facilities below capacity. The provisions in the 2022 Labor Agreements, as well as current or future proposed labor legislation or regulations, could unfavorably impact certain business activities including pricing, operating costs, margins and/or our competitiveness in the marketplace.

Financial Risk Factors

Our business and execution of our strategy require substantial expenditures for capital investments, debt service obligations, operating leases and maintenance that we may be unable to fund, which may require other actions to satisfy our obligations under our debt.

We have approximately $3.9 billion of total debt (see Note 17 to the Consolidated Financial Statements). If our cash flows and capital resources are insufficient to fund our planned capital expenditures or debt service obligations, we may face substantial liquidity problems and may be forced to reduce or delay investments and capital expenditures, terminate strategic projects, or to dispose of material assets or operations or issue additional debt or equity. We may not be able to take such actions, if necessary, on commercially reasonable terms or at all. The Credit Facility Agreement, the documents governing the USSK Credit Facility, the documents governing the Big River Steel ABL Facility and Big River Steel notes, and the indentures governing our existing senior unsecured notes may restrict our ability to dispose of assets and may also restrict our ability to raise debt or equity capital to be used to repay other debt when it becomes due. We may not be able to consummate those dispositions or to obtain proceeds in an amount sufficient to meet any debt service obligations then due. Our inability to generate sufficient cash flows to satisfy our debt obligations, or to refinance our indebtedness on commercially reasonable terms or at all, would materially and adversely affect our financial position and results or operations and may place us at a competitive disadvantage with competitors who may have less indebtedness and other obligations or greater access to financing. In addition, the availability under our Credit Facility Agreement and Big River ABL Facility may be reduced if we have insufficient collateral, or if we do not meet a fixed charge coverage ratio test. Availability under the USSK Credit Agreement could be limited if USSK does not meet certain financial covenants.

Our ability to service or refinance our debt or fund investments and capital expenditures required to maintain or expand our business operations depends on our financial condition and operating performance, which are subject to prevailing economic and competitive conditions and to certain financial, business, legislative, regulatory and other factors beyond our control, such as inflation, rising interest rates, supply chain disruptions and the impacts of the war in Ukraine. We may not be able to maintain a level of cash flows from operating activities sufficient to permit us to satisfy our liquidity needs. In addition, the availability under certain of our debt instruments may be limited if we do not meet certain financial covenants. Furthermore, the agreements governing the BRS ABL Facility and other outstanding indebtedness of Big River Steel LLC and its subsidiaries limit their ability, subject to certain exceptions, to pay dividends or distributions or make other restricted payments, such that we may not be able to access the cash generated by these subsidiaries to fund our other expenditures.

If we cannot make scheduled payments on our debt, we will be in default and holders of our senior unsecured notes could declare all outstanding principal and interest to be due and payable, the lenders under the Sixth Amended and Restated Credit Agreement, the USSK Credit Facility and the Export Credit Facility could terminate their commitments to loan money, accelerate full repayment of any or all amounts outstanding (which may result in the cross acceleration of certain of our other debt obligations) and the lenders could foreclose against the assets securing their borrowings and we could be forced into bankruptcy or liquidation. All of these events would materially and adversely affect our financial position and results of operations.

Furthermore, ratings agencies could downgrade our ratings either due to factors specific to our business, a prolonged cyclical downturn in the steel industry, macroeconomic trends such as global or regional recessions and trends in credit and capital markets more generally. Ratings agencies also may lower, suspend or withdraw ratings on the outstanding securities of U. S. Steel or Big River Steel. Any lowering, suspension or withdrawal of such ratings may have an adverse effect on the market prices of such securities.

Any decline in our operating results or downgrades in our credit ratings may make raising capital or entering into any business transaction more difficult, lead to reductions in the availability of credit or increased cost of credit, adversely affect the terms of future borrowings, may limit our ability to take advantage of potential business opportunities, may have an adverse effect on the terms under which we purchase goods and services, and lead to reductions in the availability of credit.

We have significant retiree health care, retiree life insurance and pension plan costs, which may negatively affect our results of operations and cash flows.

We maintain retiree health care and life insurance and defined benefit pension plans covering many of our domestic employees and former employees upon their retirement. Some of these benefit plans are not fully funded, and thus will require cash funding in future years. Minimum contributions to domestic qualified pension plans (other than contributions to the Steelworkers Pension Trust (SPT) described below) are regulated under the Employee Retirement Income Security Act of 1974 (ERISA) and the Pension Protection Act of 2006 (PPA).

Table of Contents

The level of cash funding for our defined benefit pension plans in future years depends upon various factors, including voluntary contributions that we may make, future pension plan asset performance, actual interest rates under the law, the impact of business acquisitions or divestitures, union negotiated benefit changes and future government regulations, many of which are not within our control. In addition, assets held by the trusts for our pension plan and our trust for retiree health care and life insurance benefits are subject to the risks, uncertainties and variability of the financial markets. Future funding requirements could also be materially affected by differences between expected and actual returns on plan assets, actuarial data and assumptions relating to plan participants, the discount rate used to measure the pension obligations and changes to regulatory funding requirements. See "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" and Note 18 to the Consolidated Financial Statements for a discussion of assumptions and further information associated with these benefit plans.

U. S. Steel contributes to a domestic multiemployer defined benefit pension plan, the SPT, for USW-represented employees formerly employed by National Steel and represented employees hired after May 2003. We have legal requirements for future funding of this plan should the SPT become significantly underfunded or we decide to withdraw from the plan. Either of these scenarios may negatively impact our future cash flows. The 2022 Labor Agreements increased the contribution rate for most steelworker employees. Collectively bargained company contributions to the plan could increase further as a result of future changes agreed to by the Company and the USW.

The accounting treatment of goodwill, equity method investments and other long-lived assets could result in future asset impairments, which would reduce our earnings.

We periodically test our goodwill, equity method investments and other long-lived assets to determine whether their estimated fair value is less than their value recorded on our balance sheet. The results of this testing for potential impairment may be adversely affected by uncertain market conditions for the global steel industry and general economic conditions. If we determine that the fair value of any of these assets is less than the value recorded on our balance sheet, and, in the case of equity method investments the decline is other than temporary, we would likely incur a non-cash impairment loss that would negatively impact our results of operations. We have incurred asset impairment charges in recent years, including during the year ended December 31, 2022, and there can be no assurances that continued market dynamics or other factors may not result in future impairment charges.

We are subject to foreign currency risks, which may negatively impact our profitability and cash flows.

The financial condition and results of operations of USSE are reported in euros and then translated into U.S. dollars at the applicable exchange rate for inclusion in our financial statements. The appreciation of the U.S. dollar against the euro negatively affects our Consolidated Results of Operations. International cash requirements have been and in the future may be funded by intercompany loans, which may create intercompany monetary assets and liabilities in currencies other than the functional currencies of the entities involved, which can have a non-cash impact on income when they are remeasured at the end of each period. Procurement of equipment of announced strategic projects may be denominated in foreign currencies, which could adversely affect the costs of these projects.

In addition, foreign producers, including foreign producers of subsidized or unfairly traded steel with foreign currency denominated costs may gain additional competitive advantages or target our home markets if the U.S. dollar or euro exchange rates strengthen relative to those producers' currencies. Volatility in the markets and exchange rates for foreign currencies and contracts in foreign currencies could have a significant impact on our reported financial results and condition.

Financial regulatory frameworks introduced by U.S. and EU regulators may limit our financial flexibility or increase our costs.

We use swaps, forward contracts and similar agreements to mitigate our exposure to volatility, which entails a variety of risks. The Commodity Future Trading Commission’s Dodd Frank and the EU’s European Market Infrastructure Regulation and other government agencies' regulatory frameworks can limit the Company’s ability to hedge interest rate, foreign exchange (FX), or commodity pricing exposures, which could expose us to increased economic risk. These frameworks may introduce additional compliance costs or liquidity requirements. Some counterparties may cease hedging as a result of increased regulatory cost burdens, which in turn may reduce U. S. Steel’s ability to hedge its interest rate, FX or commodity exposures.

We are a party to various legal proceedings, the resolution of which could negatively affect our profitability and cash flows in a particular period.

We are involved at any given time in various litigation matters, including administrative and regulatory proceedings, governmental investigations, environmental matters and commercial disputes. Our profitability and cash flows in a particular period could be negatively affected by an adverse ruling or settlement in any legal proceeding or investigation. While we believe that we have taken appropriate actions to mitigate and effectively manage these risks, due to the nature of our operations, these risks will continue to exist and additional legal proceedings or investigations may arise from time to time.

Table of Contents

Additionally, we may be subject to product liability claims that may have an adverse effect on our financial position, results of operations and cash flows. Events such as well failures, line pipe leaks, blowouts, bursts, fires and product recalls could result in claims that our products or services were defective and caused death, personal injury, property damage or environmental pollution. The insurance we maintain may not be adequate, available to protect us in the event of a claim, or its coverage may be limited, canceled or otherwise terminated, or the amount of our insurance may be less than the related impact on our enterprise value after a loss. We establish reserves based on our assessment of contingencies, including contingencies for claims asserted against us in connection with litigation, arbitrations and environmental issues. Adverse developments in litigation, arbitrations, environmental issues or other legal proceedings may affect our assessment and estimates of the loss contingency recorded as a reserve and require us to make payments in excess of our reserves, which could negatively affect our operations, financial results and cash flows. See "Item 3. Legal Proceedings" and Note 26 to the Consolidated Financial Statements for further details.

Regulatory Risk Factors

Compliance with existing and new environmental regulations, environmental permitting and approval requirements may result in delays or other adverse impacts on planned projects, our results of operations and cash flows.

Steel producers in the U.S., along with their customers and suppliers, are subject to numerous federal, state and local laws and regulations relating to the protection of the environment. These laws and regulations concern the generation, storage, transportation, disposal, emission or discharge of pollutants, contaminants and hazardous substances into the environment, the reporting of such matters, and the general protection of public health and safety, natural resources, wildlife and the environment. Steel producers in the EU are subject to similar laws. These laws and regulations continue to evolve and are becoming increasingly stringent. The ultimate impact of complying with such laws and regulations is not always clearly known or determinable because regulations under some of these laws have not yet been promulgated or are undergoing revision. Additionally, compliance with certain of these laws and regulations, such as the CAA and similar state and local requirements, governing air emissions, could result in substantially increased capital requirements and operating costs and could change the equipment or facilities we operate. Compliance with current or future regulations could entail substantial costs for emission-based systems and could have a negative impact on our results of operations and cash flows. Failure to comply with the requirements may result in administrative, civil and criminal penalties, revocation of permits to conduct business or construct certain facilities, substantial fines or sanctions, enforcement actions (including orders limiting our operations or requiring corrective measures), natural resource damages claims, cleanup and closure costs, and third-party claims for property damage and personal injury as a result of violations of, or liabilities under, environmental laws, regulations, codes and common law. The amount and timing of environmental expenditures is difficult to predict, and, in some cases, liability may be imposed without regard to contribution or to whether we knew of, or caused, the release of hazardous substances.

In addition, the Company must obtain, maintain and comply with numerous permits, leases, approvals, consents and certificates from various governmental authorities in connection with the construction and operation of new production facilities or modifications to existing facilities. In connection with such activities, the Company may need to make significant capital and operating expenditures to detect, repair and/or control air emissions, to control water discharges or to perform certain corrective actions to meet the conditions of the permits issued pursuant to applicable environmental laws and regulations.

There can be no assurance that future approvals, licenses and permits will be granted or that we will be able to maintain and renew the approvals, licenses and permits we currently hold. Failure to do so could have a material adverse effect on our results of operations and cash flows. Furthermore, compliance with the environmental permitting and approval requirements may be costly and time consuming and could result in delays or other adverse impacts on planned projects, our results of operations and cash flows.

We have significant environmental remediation costs that negatively affect our results of operations and cash flows.

Some of U. S. Steel's current and former facilities were in operation before many federal and state environmental regulations were in place. Hazardous materials associated with those facilities have been and may continue to be encountered at current or former operating sites or delivered to sites operated by third parties.

U. S. Steel is involved in numerous remediation projects at currently operating facilities, facilities that have been closed or sold to unrelated parties and other sites where material generated by U. S. Steel was deposited. In addition, there are numerous other former operating or disposal sites that could become subject to remediation, which may negatively affect our results of operations and cash flows.

Reducing greenhouse gas (GHG) emissions from steelmaking operations to meet corporate targets or comply with new regulations as well as stakeholder expectations and mitigate potential physical impacts of climate change could significantly increase costs to manufacture future materials or reduce the amount of materials being manufactured.

Table of Contents

Iron and steel producers around the world are facing mounting pressure to reduce greenhouse gas emissions from operations. The majority of greenhouse gas emissions from the production of iron and steel are caused by the combustion of fossil fuels, the use of electrical energy, and the use of coal, lime, and iron ore as feedstock. The two main production processes are the integrated route of blast furnace ironmaking in combination with basic oxygen furnace steelmaking (BOF) and the alternative route of electric arc furnace steelmaking. Both routes generate greenhouse gas emissions with the latter process, involving the electric arc melting of a majority of steel scrap, generating less than half that of the traditional integrated steelmaking process.

Federal, state and local governmental agencies within the United States may introduce regulatory changes in response to the potential impacts of climate change, including the introduction of carbon emissions limitations or trading mechanisms. Any such regulation regarding climate change and GHG emissions could impose significant costs on our operations and on the operations of our customers and suppliers, including increased energy, capital equipment, emissions controls, environmental monitoring and reporting and other costs in order to comply with current or future laws or regulations concerning climate change and GHG emissions. Any adopted future climate change and GHG regulations could negatively impact our ability, and that of our customers and suppliers, to compete with companies situated in areas not subject to or not complying with such limitations. Inconsistency of regulations may also change the attractiveness of the locations of some of the Company's assets and investments. In addition, changes in certain environmental regulations, including those that may impose output limitations or higher costs associated with climate change or greenhouse gas emissions, could substantially increase the cost of manufacturing and raw materials to us and other steel producers. For additional details, see “Part I – Item 1, Business – New and Emerging Environmental Regulations – United States and European Greenhouse Gas Emissions Regulations” above.

Additionally, the European Union has established aggressive CO2 reduction targets of 40 percent by 2030, against a 1990 baseline, and full carbon neutrality by 2050. As part of the European Green Deal the Commission proposed in September 2020 to raise the 2030 reduction target to at least 55 percent compared to 1990. The new target has yet to be endorsed by the European Parliament. An emission trading system (ETS) was established to encourage compliance with set emissions reduction targets. These aggressive targets require drastic measures within the steel industry to comply. The transition to EAF technology, as well as incremental gains in energy reduction, use of renewable energy, hydrogen-based steelmaking and continued asset and process improvements are expected to reduce our GHG footprint. However, the development of breakthrough technologies is likely required to continue the path of low to no carbon footprint in the steel industry. Implementation of new technologies will most likely require significant amounts of capital and an abundant source of low-cost hydrogen and/or green power, most likely leading to an increase in the cost of future steelmaking. In addition, the cost of emission allowances is forecast to increase, along with the number of allowances decreasing in the next several years. The price of CO2 emission allowances was 81 euro per metric ton as of December 31, 2022 and forecasts call for potential prices exceeding 100 euro per metric ton in future years.

Environmental, social and governance matters may impact our business and reputation.

In addition to the changing rules and regulations related to environmental, social and governance (ESG) matters imposed by governmental and self-regulatory organizations such as the SEC and the New York Stock Exchange, a variety of third-party organizations and institutional investors evaluate the performance of companies on ESG topics, and the results of these assessments are widely publicized. These changing rules, regulations and stakeholder expectations have resulted in, and are likely to continue to result in, increased general and administrative expenses and increased management time and attention spent complying with or meeting such regulations and expectations. Reduced access to or increased cost of capital may occur as financial institutions and investors increase expectations related to ESG matters.

Developing and acting on initiatives within the scope of ESG, and collecting, measuring and reporting ESG-related information and metrics can be costly, difficult and time consuming and is subject to evolving reporting standards. We may also communicate certain initiatives and goals, regarding environmental matters, diversity, social investments and other ESG-related matters, in our SEC filings or in other public disclosures. These initiatives and goals within the scope of ESG could be difficult and expensive to implement, the technologies needed to implement them may not be cost effective and may not advance at a sufficient pace, and we could be criticized for the accuracy, adequacy or completeness of the disclosure. Furthermore, statements about our ESG-related initiatives and goals, and progress against those goals, may be based on standards for measuring progress that are still developing, internal controls and processes that continue to evolve and assumptions that are subject to change in the future. In addition, we could be criticized for the scope or nature of such initiatives or goals, or for any revisions to these goals. If our ESG-related data, processes and reporting are incomplete or inaccurate, or if we fail to achieve progress with respect to our goals, including our previously announced commitments to reduce greenhouse gas emissions, within the scope of ESG on a timely basis, or at all, our reputation, business, financial performance and growth could be adversely affected.

New and changing data privacy laws and cross-border transfer requirements could have a negative impact on our business and operations.

Our business depends on the processing and transfer of data between our affiliated entities, to and from our business partners, and with third-party service providers, and of our employees, which may be subject to data privacy laws and/or cross-border transfer restrictions. In North America and Europe, new legislation and changes to the requirements or applicability of existing laws, as well as evolving standards and judicial and regulatory interpretations of such laws, may impact U. S. Steel’s ability to effectively process and transfer data both within the United States and across borders in support of our business operations and/or keep pace with specific requirements regarding safeguarding and handling personal information. While U. S. Steel takes steps to comply with these legal requirements, non-compliance could lead to possible administrative, civil, or criminal liability, as well as

reputational harm to the Company and its employees. The costs of compliance with privacy laws and the potential for fines and penalties in the event of a breach may have a negative impact on our business and operations.

Item 1B. UNRESOLVED STAFF COMMENTS

None.

Item 2. PROPERTIES

See Item 1. Business, Facilities and Locations for listings of U. S. Steel’s main properties, their locations and their products and services.

U. S. Steel and its predecessors have owned their properties for many years with no material adverse title claims asserted. In the case of Great Lakes Works, Granite City Works, the Midwest Plant and Keetac iron ore operations, U. S. Steel or its subsidiaries are the beneficiaries of bankruptcy laws and orders providing that properties are held free and clear of past liens and liabilities. In addition, U. S. Steel or its predecessors obtained title insurance, local counsel opinions or similar protections when significant properties were initially acquired or since acquisition.

At the Midwest Plant in Indiana, U. S. Steel has a supply agreement for various utility services with a company that owns a cogeneration facility located on U. S. Steel property. The Midwest Plant agreement expires in 2028.

U. S. Steel leases its headquarters office space in Pittsburgh, Pennsylvania.

In accordance with Regulation S-K, Items 1300-1305, we engaged DRA Global and Barr Engineering Co. to provide feasibility studies and technical report summaries for our material mining operations at Minntac and Keetac in 2021. The majority shareholders of the Hibbing Taconite Company separately engaged qualified persons to perform the same procedures at the Hibbing Taconite Mine in 2021. Accordingly, the figures below for the Hibbing Taconite Mine were provided by the majority shareholders using the reports provided by the qualified persons. The tables showing resources and reserves by mining property were prepared using the results of the procedures performed by the qualified persons designated by each organization, which have no affiliation with or interest in our material mining properties.

Regulation S-K, Item 1302, requires registrants to file the technical report summary as an exhibit to the Form 10-K filing when disclosing for the first time mineral reserves or resources or when there has been a material change in the mineral reserves or resources since the last technical report summary filed for the properties. The Company did not have any material changes to its reserves or resources during 2022, nor is it disclosing any mineral reserves or resources for the first time. Accordingly, the technical report summary is not filed as an exhibit with the 2022 Form 10-K.

Item 3. LEGAL PROCEEDINGS

General Litigation

On June 8, 2021, JSW Steel (USA) Inc. and JSW Steel USA Ohio, Inc. (collectively, JSW), U.S. based subsidiaries of Indian steelmaker JSW Steel, filed suit in the United States District Court for the Southern District of Texas against Nucor, U. S. Steel, AK Steel Holding Group and Cleveland-Cliffs (collectively, the JSW Defendants) alleging that the Defendants operated as a cartel and formed a conspiracy to boycott JSW from obtaining semi-finished steel slabs. JSW alleges that the JSW Defendants acted in violation of Section 1 of the Sherman Act and the Clayton Act (federal antitrust), and violation of the Texas Free Enterprise and Antitrust Act. JSW also alleges that the JSW Defendants formed a civil conspiracy in violation of Texas common law, and that the JSW Defendants tortiously interfered with JSW’s business relationships. The basis for JSW’s allegations relate to the JSW Defendants participation in the DOC's Section 232 process, including the JSW Defendants’ support of the enactment of the President’s Section 232 proclamation, statements made by the JSW Defendants after the enactment of Section 232, and the JSW Defendants’ participation in the Section 232 exclusion process. Plaintiffs seek monetary damages including $45 million for payment of Section 232 tariffs and unspecified amounts for financial penalties, termination fees and lost profits as well as other damages. U. S. Steel, along with the other JSW Defendants, filed a Motion to Dismiss the case on August 17, 2021. On February 17, 2022, the Court issued an opinion dismissing JSW’s antitrust complaint with prejudice. JSW filed a timely notice of appeal with the United States Court of Appeals for the Fifth Circuit. The matter is fully briefed and is scheduled for oral argument at the Fifth Circuit in first quarter 2023. The Company continues to vigorously defend the matter.

On October 2, 2017, an Amended Shareholder Class Action Complaint was filed in the United States District Court for the Western District of Pennsylvania consolidating previously-filed actions. Separately, five related shareholder derivative lawsuits were filed in state and federal courts in Pittsburgh, Pennsylvania and the Delaware Court of Chancery. The underlying consolidated class action lawsuit alleges that U. S. Steel, certain current and former officers, an upper-level manager of the Company and the financial underwriters who participated in the August 2016 secondary public offering of the Company's common stock (collectively, the "Class Action Defendants") violated federal securities laws in making false statements and/or failing to discover and disclose material information regarding the financial condition of the Company. The lawsuit claims that this conduct caused a prospective class of plaintiffs to sustain damages during the period from January 27, 2016 to April 25, 2017 as a result of the prospective class purchasing the Company's common stock at artificially inflated prices and/or suffering losses when the price of the common stock dropped. The derivative lawsuits generally make the same allegations against the same officers and also allege that certain current and former members of the Board of Directors failed to exercise appropriate control and oversight over the Company and were unjustly compensated. The plaintiffs seek to recover losses that were allegedly sustained. The Class Action Defendants moved to dismiss plaintiffs’ claims. On September 29, 2018 the Court ruled on those motions granting them in part and denying them in part. On March 18, 2019, the plaintiffs withdrew the claims against the Class Action Defendants related to the 2016 secondary offering. As a result, the underwriters are no longer parties to the case. On December 31, 2019, the court granted the Plaintiffs' motion to certify the proceeding as a class action. The Company's appeal of that decision was denied. Discovery followed and concluded. On May 20, 2022, the Plaintiffs and Class Action Defendants agreed to settle the Shareholder Class Action in the amount of $40 million to be fully funded by the Company’s insurers. Court approval of the class action settlement is currently pending with a Final Approval Hearing set for March 20, 2023. The related derivative cases, which were previously stayed, are now proceeding and the Company will vigorously defend against the derivative lawsuits.

On December 24, 2018, U. S. Steel's Clairton Plant experienced a fire, affecting portions of the facility involved in desulfurization of the coke oven gas generated during the coking process. With the desulfurization process out of operation as a result of the fire, U. S. Steel was not able to certify compliance with Clairton Plant’s Title V permit levels for sulfur emissions. U. S. Steel promptly notified ACHD, which has regulatory jurisdiction for the Title V permit, and updated the ACHD regularly on efforts to mitigate any potential environmental impacts until the desulfurization process was returned to normal operations. Of the approximately 2,400 hours between the date of the fire and April 4, 2019, when the Company resumed desulfurization, there were ten intermittent hours where average SO2 emissions exceeded the hourly NAAQS for SO2 at the Allegheny County regional air quality monitors located in Liberty and North Braddock boroughs, which are near U. S. Steel's Mon Valley Works facilities. On April 29, 2019, PennEnvironment and Clean Air Council, both environmental, non-governmental organizations filed a Complaint in Federal Court in the Western District of Pennsylvania. The ACHD was subsequently granted intervenor status. Collectively the parties seek injunctive relief and civil penalties regarding the alleged Permit violations following the fire. Discovery has concluded. The court denied the parties’ respective Motions for Summary Judgment. A non-jury trial is currently scheduled to take place in April and May of 2023. The Company will continue to vigorously defend against the matter.

Asbestos Litigation

ENVIRONMENTAL PROCEEDINGS

The following is a summary of the proceedings of U. S. Steel that were pending or contemplated as of December 31, 2022, under federal and state environmental laws, and which U. S. Steel reasonably believes may result in monetary sanctions of at

Table of Contents

least $1 million (the threshold chosen by U. S. Steel as permitted by Item 103 of Regulation S-K promulgated under the Securities Exchange Act of 1934, as amended). Information about specific sites where U. S. Steel is or has been engaged in significant clean up or remediation activities is also summarized below. Except as described herein, it is not possible to accurately predict the ultimate outcome of these matters.

CERCLA Remediation Sites

Claims under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) have been raised with respect to the cleanup of various waste disposal and other sites. Under CERCLA, potentially responsible parties (each, a PRP) for a site include current owners and operators, past owners and operators at the time of disposal, persons who arranged for disposal of a hazardous substance at a site and persons who transported a hazardous substance to a site. CERCLA imposes strict and joint and several liabilities. Because of various factors, including the ambiguity of the regulations, the difficulty of identifying the responsible parties for any particular site, the complexity of determining the relative liability among them, the uncertainty as to the most desirable remediation techniques, and the amount of damages and cleanup costs and the time period during which such costs may be incurred, we are unable to reasonably estimate U. S. Steel’s ultimate liabilities under CERCLA.

As of December 31, 2022, U. S. Steel has received information requests or been identified as a PRP at a total of four CERCLA sites, three of which have liabilities that have not been resolved. Based on currently available information, which is in many cases preliminary and incomplete, management believes that U. S. Steel’s liability for CERCLA cleanup and remediation costs at the other site will be over $5 million as described below.

Duluth Works

The former U. S. Steel Duluth Works site was placed on the National Priorities List under CERCLA in 1983 and on the State of Minnesota’s Superfund list in 1984. Liability for environmental remediation at the site is governed by a Response Order by Consent executed with the MPCA in 1985 and a Record of Decision signed by MPCA in 1989. U. S. Steel has partnered with the Great Lakes National Program Office (GLNPO) of the U.S. EPA Region 5 to address contaminated sediments in the St. Louis River Estuary and several other operable units that could impact the estuary if not addressed. An amendment to the Project Agreement between U. S. Steel and GLNPO was executed during the second quarter of 2018 to recognize the initial costs associated with implementing the first two phases of the proposed remedial plan at the site.

Remediation contracts were issued by both USS and GLNPO for the first phase of the remedial work at the site during the fourth quarter of 2020. USS and GLNPO have completed the second phase of work at the site which extended through early 2022. The final phase of the remedial design has been defined and another amendment to the Project Agreement between U.S. Steel and GLNPO was executed in December 2021. Execution of this final phase is in progress and is expected to extend through 2023. USS' portion of additional, design, oversight costs and implementation of all three phases of the preferred remedial alternative on the upland property and Estuary are currently estimated as of December 31, 2022 at approximately $22 million.

Resource Conservation Recovery Act (RCRA) and Other Remediation Sites

U. S. Steel may be liable for remediation costs under other environmental statutes, both federal and state, or where private parties are seeking to impose liability on U. S. Steel for remediation costs through discussions or litigation. There are nine such sites where remediation is being sought involving amounts in excess of $1 million. Based on currently available information, which is in many cases preliminary and incomplete, management believes that liability for cleanup and remediation costs in connection with five sites may involve remediation costs between $1 million and $5 million per site and four sites are estimated to, or could have, costs for remediation, investigation, restoration or compensation in excess of $5 million per site.

For more information on the status of remediation activities at U. S. Steel’s significant sites, see the discussions below.

Gary Works

On October 23, 1998, the U.S. EPA issued a final Administrative Order on Consent (Order) addressing Corrective Action for Solid Waste Management Units (SWMU) throughout Gary Works. This Order requires U. S. Steel to perform a RCRA Facility Investigation (RFI), a Corrective Measures Study (CMS) and Corrective Measure Implementation. Evaluations are underway at six groundwater areas on the east side of the facility. A remedial groundwater treatment system has been operating at one of the six areas since 2021. An Interim Stabilization Measure work plan was recently approved by the U.S. EPA for a second area and a contractor has begun installation of the remedial system. Until the remaining Phase I work and Phase II field investigations are completed, it is not possible to assess what additional expenditures will be necessary for Corrective Action projects at Gary Works. In total, the accrued liability for Corrective Action projects is approximately $28 million as of December 31, 2022, based on our current estimate of known remaining costs.

Geneva Works

At U. S. Steel’s former Geneva Works, liability for environmental remediation, including the closure of three hazardous waste impoundments and facility-wide corrective action, has been allocated between U. S. Steel and the current property owner pursuant to an agreement and a permit issued by the Utah Department of Environmental Quality (UDEQ). Having completed the

Table of Contents

investigation on a majority of the remaining areas identified in the permit, U. S. Steel had determined the most effective means to address the majority of impacted materials was to manage those materials in a previously approved on-site Corrective Action Management Unit (CAMU). U. S. Steel awarded a contract for the implementation of the CAMU project during the fourth quarter of 2018. Construction, waste stabilization and placement along with closure of the CAMU were substantially completed in the fourth quarter of 2020. U. S. Steel has an accrued liability of approximately $19 million as of December 31, 2022, for our estimated share of the remaining costs of remediation at the site.

USS-UPI LLC (UPI)

In February 2020, U. S. Steel purchased the remaining 50 percent interest in USS-POSCO Industries, a former joint venture that is located in Pittsburg, California between subsidiaries of U. S. Steel and POSCO, now known as USS-UPI, LLC. Prior to formation of the joint venture, UPI's facilities were previously owned and operated solely by U. S. Steel, which assumed responsibility for the existing environmental conditions. U. S. Steel continues to monitor the impacts of the remedial plan implemented in 2016 to address groundwater impacts from trichloroethylene at SWMU 4. Evaluations continue for the SWMUs, known as the Northern Boundary Group, and it is likely that corrective measures will be required, but it is not possible at this time to define a scope or estimate costs for what may be required by the California Department of Toxic Substances Control. As such, there has been no material change in the status of the project during the twelve months ended December 31, 2022. As of December 31, 2022, approximately $1 million has been accrued for ongoing environmental studies, investigations and remedy monitoring. Significant additional costs associated with this site are possible and are referenced in Note 26 to the Consolidated Financial Statements, Contingencies and Commitments, Environmental Matters, Remediation Projects, Projects with Ongoing Study and Scope Development. See Note 5 to the Consolidated Financial Statements for further details regarding U. S. Steel's purchase of UPI.

Cherryvale, KS Zinc

In April 2003, U. S. Steel and Salomon Smith Barney Holdings, Inc. entered into a Consent Order with the Kansas Department of Health & Environment (KDHE) concerning a former zinc smelting operation in Cherryvale, Kansas. Remediation of the site proper was essentially completed in 2007. The Consent Order was amended on May 3, 2013 to require investigation (but not remediation) of potential contamination beyond the boundary of the former zinc smelting operation. On November 22, 2016, KDHE approved a State Cooperative Final Agency Decision Statement that identified the remedy selected to address potential contamination beyond the boundary of the former zinc smelting site. The Removal Action Design Plan was approved during the second quarter of 2018. The Waste Deposition Area design and the Interim Risk Management Plan (which includes institutional controls) were approved by KDHE during the fourth quarter of 2018. An amended consent order for remediation was signed in May 2019 and a remediation contract was executed in June 2019. Remediation work was substantially completed in the 4th quarter of 2022. U. S. Steel has an accrued liability of approximately $908,000 as of December 31, 2022, for our estimated share of the remaining cost of remediation.

Fairfield Works

A consent decree was signed by U. S. Steel, the U.S EPA and the U.S. Department of Justice and filed with the United States District Court for the Northern District of Alabama (United States of America v. USX Corporation) in December 1997. In accordance with the consent decree, U. S. Steel initiated a RCRA corrective action program at the Fairfield Works facility. The Alabama Department of Environmental Management, with the approval of the U.S. EPA, assumed primary responsibility for regulation and oversight of the RCRA corrective action program at Fairfield Works. While work continues on different aspects of the program, there has been no material change in the status of the project during the year ended December 31, 2022. In total, the accrued liability for remaining work under the Corrective Action Program, was approximately $377,000 at December 31, 2022. Significant additional costs associated with this site are possible and are referenced in Note 26 to the Consolidated Financial Statements “Contingencies and Commitments, Environmental Matters, Remediation Projects, Projects with Ongoing Study and Scope Development.”

Air Related Matters

Granite City Works

In October 2015, Granite City Works received a Violation Notice from Illinois Environmental Protection Agency (IEPA) in which the IEPA alleges that U. S. Steel violated the emission limits for nitrogen oxides (NOx) and volatile organic compounds from the Basic Oxygen Furnace Electrostatic Precipitator Stack. In addition, the IEPA alleges that U. S. Steel exceeded its natural gas usage limit at its CoGeneration Boiler. U. S. Steel responded to the notice and is currently discussing resolution of the matter with IEPA.

Although discussions with IEPA regarding the foregoing alleged violations are ongoing and the resolution of these matters is uncertain at this time, it is not anticipated that the result of those discussions will be material to U. S. Steel.

Minnesota Ore Operations

Table of Contents

On February 6, 2013, the U.S. EPA published a FIP that applies to taconite facilities in Minnesota. The FIP establishes and requires emission limits and the use of low NOx reduction technology on indurating furnaces as Best Available Retrofit Technology (BART). While U. S. Steel installed low NOx burners on three furnaces at Minntac and is currently obligated to install low NOx burners on the two other furnaces at Minntac pursuant to existing agreements and permits, the rule would require the installation of a low NOx burner on the one furnace at Keetac for which U. S. Steel did not have an otherwise existing obligation. U. S. Steel estimates expenditures associated with the installation of low NOx burners of as much as $25 million to $30 million. In 2013, U. S. Steel filed a petition for administrative reconsideration to the U.S. EPA and a petition for judicial review of the 2013 FIP and denial of the Minnesota State Implementation Plan (SIP) to the Eighth Circuit. In April 2016, the U.S. EPA promulgated a revised FIP with the same substantive requirements for U. S. Steel. In June 2016, U. S. Steel filed a petition for administrative reconsideration of the 2016 FIP to the U.S. EPA and a petition for judicial review of the 2016 FIP before the Eighth Circuit Court of Appeals. While the proceedings regarding the petition for judicial review of the 2013 FIP remained stayed, oral arguments regarding the petition for judicial review of the 2016 FIP were heard by the Eighth Circuit Court of Appeals on November 15, 2017. Thus, both petitions for judicial review remain with the Eighth Circuit. On December 4, 2017, the U.S. EPA published a notification in the Federal Register in which the U.S. EPA denied U. S. Steel’s administrative petitions for reconsideration and stay of the 2013 FIP and 2016 FIP. On February 1, 2018, U. S. Steel filed a petition for judicial review of the U.S. EPA’s denial of the administrative petitions for reconsideration to the Eighth Circuit Court of Appeals. The U.S. EPA and U. S. Steel reached a settlement regarding the five indurating lines at Minntac. After proposing a revised FIP and responding to public comments, on March 2, 2021, the U.S. EPA promulgated a final revised FIP incorporating the conditions and limits for Minntac to which the parties agreed. U. S. Steel and the U.S. EPA continue to negotiate resolution for Keetac.

Mon Valley Works

On November 9, 2017, the U.S. EPA Region III and ACHD jointly issued a Notice of Violation (NOV) regarding the Company’s Edgar Thomson facility in Braddock, Pennsylvania. In addition, on November 20, 2017, ACHD issued a separate, but related, NOV to the Company regarding the Edgar Thomson facility. In the NOVs, based upon their inspections and review of documents collected, the agencies allege that the Company has violated the CAA by exceeding the allowable visible emission standards from certain operations during isolated events. In addition, the agencies allege that the Company has violated certain maintenance, reporting, and recordkeeping requirements. U. S. Steel met with the U.S. EPA Region III and ACHD several times. On May 17, 2022, the United States Department of Justice (the DOJ), the U.S. EPA Region III and the ACHD filed a Complaint in the United States District Court for the Western District of Pennsylvania and lodged a proposed Consent Decree negotiated in good faith between U. S. Steel, DOJ, the U.S. EPA Region III and ACHD that will resolve this matter. On December 16, 2022, the Court approved the Consent Decree and it is currently in effect.

On March 2, 2022, the Company received a stipulated penalty demand for $0.9 million from the Allegheny County Health Department (ACHD) pursuant to the June 2019 Settlement Agreement and Order (SAO) between the Company and ACHD. In the demand notice, ACHD alleges that based upon daily visible emission observation inspections occurring April 1, 2021 through December 31, 2021, the Company’s Clairton plant violated applicable opacity standards from coke battery fugitive emission sources. The Company disagrees with the bases for the demand. The Company has initiated dispute resolution in accordance with the SAO and is attempting to reach a negotiated resolution of the matter.

On March 7, 2022, the Company received an enforcement order from the ACHD that includes a civil penalty demand for $1.8 million. In the Order, the ACHD alleges that the Company’s Clairton plant is solely and entirely culpable for 153 alleged exceedances of the Pennsylvania hydrogen sulfide ambient air standard that are reported to have occurred during January 1, 2020 through March 1, 2022. The Company disagrees with the bases for the demand. On April 5, 2022, the Company appealed the Order and is vigorously defending the matter. On September 1, 2022, after conferring with ACHD and the Company, the ACHD Hearing Officer issued an order requiring discovery to be completed by June 1, 2023 with a hearing date of September 18, 2023.

On March 24, 2022, the Company received an enforcement order from the ACHD that includes a civil penalty demand for $4.6 million for alleged air permit violations occurring between January 1, 2020 through March 15, 2022 regarding the Company’s Clairton plant’s coke oven pushing emission control systems. The Company disagrees with the bases for the demand and has appealed the Order. On September 1, 2022, after conferring with ACHD and the Company, the ACHD Hearing Officer issued an order requiring discovery to be completed by June 1, 2023 with a hearing date of September 25, 2023.

Item 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion should be read in conjunction with the Consolidated Financial Statements and the related Notes that appear elsewhere in this document. Please refer to Item 7 of our 2021 Form 10-K for further discussion and analysis of our 2020 financial condition and results of operations.

Overview

2022 marked our second-best financial year in the Company's history with continued execution of our strategy. Each of our operating segments contributed meaningfully to 2022's success, while delivering record safety performance and strong operational excellence, quality, and reliability for our customers. We continued to invest in our future by progressing on key strategic projects and we also rewarded stockholders in 2022 with direct returns, including a quarterly dividend and share repurchases. In the second half of 2022, we quickly responded to changing market dynamics by temporarily idling certain operations to better balance steel supply with customer demand.

U. S. Steel's results in 2022 compared to the previous year for the four reportable segments, except for Tubular Products (Tubular), generally declined from challenging business conditions:

Table of Contents

•North American Flat-Rolled (Flat-Rolled): Flat-Rolled results declined primarily due to lower sales volume across most consumer and manufacturing industries and increased material, energy and operating costs, partially offset by higher sales price.

•Mini Mill: Mini Mill results declined primarily due to lower sales prices and higher raw material costs.

•U. S. Steel Europe (USSE): USSE results declined primarily due to lower sales volume, increased raw material and energy costs and the weakening euro exchange rate, partially offset by higher sales price.

•Tubular: Tubular results improved primarily due to increased volume, higher sales price and improved premium product mix, driven by the steady increase of drilling activity, partially offset by continued high levels of imports.

Fluctuations in the market price of raw materials and other inflationary impacts have affected the results of each of our reportable segments, and fluctuations going-forward are reasonably likely to have a material impact on future results. We could experience inflation related headwinds in 2023 for certain raw materials and other costs.

In February 2022, Russia invaded Ukraine and active conflict continues in the country. The war in Ukraine will likely continue to cause disruption and instability in Russia, Ukraine, as well as the markets in which we operate. The Company is constantly monitoring the situation for impacts and risks to the business and is implementing risk mitigating strategies where possible.

As a result of the invasion, governments around the world, including the European Union (EU) and the United States of America (U.S.), have enacted sanctions against Russia and Russian interests. We are complying with all applicable sanctions that impact our business.

USSE purchases certain raw materials from sources that procure supply from Russia, including natural gas and iron ore. Since the onset of the war, and before, USSE has been building its inventory of iron ore and coal and procuring them through alternate sources. Current levels of iron ore and coal are sufficient to serve customer demand through the end of the first quarter 2023.

With the EU prohibiting purchases of coal from suppliers in Russia, new purchases of coal originating from Russia have stopped. The Company has built up sufficient inventory on site or in-transit to meet current customer demand. Efforts to secure alternate sources of supply are underway to continue meeting demand.

Critical Accounting Estimates

Management’s discussion and analysis of U. S. Steel’s financial condition and results of operations is based upon U. S. Steel’s financial statements, which have been prepared in accordance with accounting standards generally accepted in the United States (U.S. GAAP). The preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at year-end and the reported amount of revenues and expenses during the year. Management regularly evaluates these estimates, including those related to employee benefits liabilities and assets held in trust relating to such liabilities; the carrying value of property, plant and equipment; intangible assets; valuation allowances for receivables, inventories and deferred income tax assets; liabilities for deferred income taxes; potential tax deficiencies; environmental obligations; potential litigation claims and settlements and put and call option assets and liabilities. Management’s estimates are based on historical experience, current business and market conditions, and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ materially from current expectations under different assumptions or conditions.

Management believes that the following are the more significant judgments and estimates used in the preparation of the financial statements.

Goodwill and intangible assets – Goodwill represents the excess of the cost over the fair value of acquired identifiable tangible and intangible assets and liabilities assumed from businesses acquired. Goodwill and intangible assets deemed to have indefinite lives are not amortized, but are subject to impairment testing annually, or more frequently if events or changes in circumstances indicate the asset might be impaired. We perform our annual goodwill impairment test as of October 1 and monitor for interim triggering events on an ongoing basis.

Table of Contents

on the present value of discounted cash flows, to the respective carrying value, which includes goodwill. If the fair value of the reporting unit exceeds its carrying value, we do not consider the goodwill impaired. If the carrying value is higher than the fair value, we recognize the difference as an impairment loss.

A quantitative goodwill impairment testing process requires valuation of the respective reporting unit, which we primarily determine using an income approach based on a discounted five year forecasted cash flow including a terminal value. We compute the terminal value using the constant growth method, which values the forecasted cash flows in perpetuity. The assumptions about future cash flows and growth rates are based on the respective reporting unit's long-term forecast and are subject to review and approval by senior management. A reporting unit's discount rate is a significant assumption and is a risk-adjusted weighted average cost of capital, which we believe approximates the rate from a market participant's perspective. The estimated fair value could be impacted by changes in market conditions, interest rates, growth rates, tax rates, costs, pricing and capital expenditures. We categorize the fair value determination as Level 3 in the fair value hierarchy due to its use of internal projections and unobservable measurement inputs.

Our Mini Mill reporting unit holds the goodwill recognized as a result of the Company's acquisition of Big River Steel and currently is our only reporting unit that has a significant amount of goodwill. This goodwill is primarily attributable to Big River Steel's operational abilities, workforce and the anticipated benefits from their recent expansion. U. S. Steel completed its annual goodwill impairment test using a quantitative analysis during the fourth quarter of 2022 and determined there was no impairment of goodwill.

Intangible assets with indefinite lives are also subject to at least annual impairment testing, which compares the fair value of the intangible assets with their carrying amounts. U. S. Steel has determined that certain of its acquired intangible assets have indefinite useful lives. These assets are also reviewed for impairment annually in the fourth quarter and whenever events or circumstances indicate the carrying value may not be recoverable. U. S. Steel completed its annual evaluation of its indefinite-lived water rights using a qualitative assessment and determined there was no indication of impairment. Key assumptions included in this test relate to the relevant market rate of an acre foot of water.

If business conditions deteriorate or other factors have an adverse effect on our qualitative and quantitative estimates, inclusive of discounted future cash flows or assumed growth rates, or if we experience a sustained decline in our market capitalization, future assessments of goodwill for impairment may result in impairment charges.

Finite-lived intangible assets are amortized on a straight-line basis over their estimated useful lives and are tested for impairment when events occur that indicate that the net book value will not be recovered over future cash flows.

Business combinations – We account for business combinations under the acquisition method of accounting in accordance with ASC Topic 805, Business Combinations, which requires an allocation of the consideration we paid to the identifiable assets, intangible assets and liabilities based on the estimated fair values as of the closing date of the acquisition. The excess of the fair value of the purchase price over the fair values of these identifiable assets, intangible assets and liabilities is recorded as goodwill.

Purchased intangibles are initially recognized at fair value and amortized over their useful lives unless those lives are determined to be indefinite. The valuation of acquired assets will impact future operating results. The fair value of identifiable intangible assets is determined using an income approach on an individual asset basis. Specifically, we use the multi-period excess earnings method to estimate the fair value of the customer relationships intangible asset. Determining the fair value of the customer relationships intangible asset involves significant judgements and assumptions, including expected realized price, base year metallic costs, contributory asset charges, and customer attrition rate.

Inventories – Inventories are carried at the lower of cost or market for last-in, first-out (LIFO), moving average and first-in, first-out (FIFO) method inventories. The predominant method of inventory costing for Flat-Rolled and Tubular is LIFO. The Mini Mill segment uses FIFO for raw materials and a moving average costing method to account for semi-finished and finished products. FIFO is the predominant inventory costing method used by the USSE segment. The LIFO method of inventory costing was used on 43 percent and 46 percent of consolidated inventories at December 31, 2022 and 2021, respectively. Since the LIFO inventory valuation methodology is an annual calculation, interim estimates of the annual LIFO valuation are required. We recognize the effects of the LIFO inventory valuation method on an interim basis by estimating the year-end inventory amounts. The projections of annual LIFO inventory amounts are updated quarterly. Changes in U.S. GAAP rules or tax law, such as the elimination of the LIFO method of accounting for inventories, could negatively affect our profitability and cash flow.

Pensions and Other Benefits – The recording of net periodic benefit costs for defined benefit pensions and Other Benefits is based on, among other things, assumptions of the expected annual return on plan assets, discount rate, mortality, escalation or other changes in retiree health care costs and plan participation levels. Changes in the assumptions or differences between actual and expected changes in the present value of liabilities or assets of U. S. Steel’s plans could cause net periodic benefit costs to increase or decrease materially from year to year as discussed below.

U. S. Steel’s investment strategy for its U.S. pension and Other Benefits plan assets provides for a diversified mix of high-quality bonds, public equities and selected smaller investments in private equities, private credit, timber and mineral interests. For its

Table of Contents

U.S. pension, U. S. Steel has a target allocation for plan assets of 50 percent in fixed income investments. The balance is invested in equity securities, timber, private equity and real estate partnerships. U. S. Steel believes that returns on equities over the long term will be higher than returns from fixed-income securities as actual historical returns from U. S. Steel’s trusts have shown. Returns on bonds tend to offset some of the short-term volatility of stocks. Both equity and fixed-income investments are made across a broad range of industries and companies (both domestic and foreign) to provide protection against the impact of volatility in any single industry as well as company specific developments. U. S. Steel will use a 6.90 percent assumed rate of return on assets for the development of net periodic cost for the main defined benefit pension plan in 2023. Actual returns since the inception of the plan have exceeded this 6.90 percent rate and while recent annual returns have been volatile, it is U. S. Steel’s expectation that rates will achieve this level in future periods.

For its Other Benefits plan, U. S. Steel is employing a liability driven investment strategy. The plan assets are allocated to match the plan cash flows with maturing investments. To achieve this strategy, U. S. Steel has a target allocation for plan assets of 88 percent in fixed income and private credit. The balance is primarily invested in equity securities, timber, private equity and real estate partnerships. U. S. Steel will use a 4.50 percent assumed rate of return on assets for the development of net periodic cost for its Other Benefit plans for 2023. The 2023 assumed rate of return was updated after a review of capital market forecasted returns based on target allocations. The expected asset return for 2023 will continue to be 4.50 percent.

The expected long-term rate of return on plan assets is applied to the market value of assets as of the beginning of the period less expected benefit payments and considering any planned contributions.

To determine the discount rate used to measure our pension and Other Benefit obligations for U.S. plans we utilize a bond matching approach to select specific bonds that would satisfy our projected benefit payments. At December 31, 2022, the weighted average discount rate used for our pension and Other Benefit obligations was determined to be 5.55 percent and 5.66 percent, respectively, compared to the weighted average discount rate used of 3.01 percent and 3.11 percent, respectively, at December 31, 2021. The discount rate reflects the current rate at which we estimate the pension and Other Benefits liabilities could be effectively settled at the measurement date.

U. S. Steel reviews its actual historical rate experience and expectations of future health care cost trends to determine the escalation of per capita health care costs under U. S. Steel’s benefit plans. Approximately 75 percent of our costs for the domestic United Steelworkers (USW) participants’ retiree health benefits in the Company’s main domestic benefit plan are limited to a per capita dollar maximum calculation based on 2006 base year actual costs incurred under the main U. S. Steel benefit plan for USW participants (cost cap). The full effect of the cost cap is expected to be realized around 2030. After 2030, the Company’s costs for a majority of USW retirees and their dependents are expected to remain fixed and as a result, the cost impact of health care escalation for the Company is projected to be limited for this group (see Note 18 to the Consolidated Financial Statements). For measurement of its domestic retiree medical plans where health care cost escalation is applicable, U. S. Steel has assumed an initial escalation rate of 6.00 percent for 2023. This rate is assumed to decrease gradually to an ultimate rate of 4.50 percent in 2038 and remain at that level thereafter.

Net periodic pension benefit cost (credit), including multiemployer plans, is expected to total approximately $39 million in 2023 compared to $6 million in 2022. Excluding settlement and special termination losses totaling $12 million in 2022, the increase in net periodic pension benefit cost in 2023 is primarily due to 2022 asset performance and an increase in prior service cost. Net periodic other benefit (credit) in 2023 is expected to be approximately $(83) million, compared to $(108) million in 2022. The expected decrease in the 2023 net periodic other benefit (credit) is primarily due to the transfer of $595 million in surplus funds from the Post Retirement Benefit Trust (VEBA) assets to be used for active insurance benefits. See Note 18 to the Consolidated Financial Statements, “Pensions and Other Benefits.”

The table below projects the incremental effect of a hypothetical one percentage point change in significant assumptions used in determining the funded status and net periodic benefit cost for pension and other benefits:


	Hypothetical Rate Change Increase (Decrease)
(In millions)	1%		(1)%
Expected return on plan assets
Incremental (decrease) increase in:
Net periodic pension and other benefits costs for 2023	$	(60)	$	60
Discount rate
Incremental (decrease) increase in:
Net periodic pension and other benefits costs for 2023	$	(4)	$	11
Pension & other benefits obligations at December 31, 2022	$	(411)	$	474

Changes in the assumptions for expected annual return on plan assets and the discount rate used for accounting purposes do not impact the funding calculations used to derive minimum funding requirements for the pension plan. However, the discount rate required for minimum funding purposes is also based on corporate bond related indices and as such, the same general

Table of Contents

sensitivity concepts as above can be applied to increases or decreases to the funding obligations of the plans assuming the same hypothetical rate changes. See Note 18 to the Consolidated Financial Statements for a discussion regarding legislation enacted in March of 2021 that impacts the discount rate used for funding purposes. For further cash flow discussion see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations, Liquidity and Capital Resources.”

Long-lived assets – U. S. Steel evaluates long-lived assets, primarily property, plant and equipment for impairment whenever changes in circumstances indicate that the carrying amounts of those productive assets exceed their recoverable amount as determined by the asset group's projected undiscounted cash flows. We evaluate the impairment of long-lived assets at the asset group level. Our primary asset groups are Flat-Rolled, Mini Mill, USSE, welded tubular and seamless tubular.

In the second quarter of 2022, the Company recognized charges of $151 million for the write-off of the blast furnaces and related fixed assets for the permanent idling of the iron making process at our Great Lakes Works facility, which had been idled on an indefinite basis during 2020. There were no other triggering events that required an impairment evaluation of our long-lived asset groups during the year-ended December 31, 2022.

In the fourth quarter of 2021, U. S. Steel decided to permanently idle the steelmaking assets at Great Lakes Works, which had been indefinitely idled since 2020, resulting in an impairment of $128 million for property, plant and equipment.

Taxes - U. S. Steel records a valuation allowance, related to certain state net operating losses, state tax credits and unused capital losses, to reduce deferred tax assets to the amount that is more likely than not to be realized. A valuation allowance is recorded if, based on the weight of all available positive and negative evidence, it is more likely than not that some portion, or all, of a deferred tax asset will not be realized. Each quarter U. S. Steel analyzes the likelihood that our deferred tax assets will be realized. In the future, if we determine that it is more likely than not that we will be able to realize all or a portion of our deferred tax assets, the valuation allowance will be reduced, and we will record a non-cash net benefit to earnings.

In 2021, U. S. Steel determined, based upon weighing all positive and negative evidence, that a full valuation allowance for the domestic deferred tax assets was no longer required. Accordingly, we reversed all of the domestic valuation allowance except for a portion of the domestic valuation allowance related to certain state net operating losses and state tax credits. During the year ended December 31, 2021, we realized a non-cash net benefit of $715 million related to the valuation allowance release, which was partially offset by the addition of a valuation allowance of $82 million, the majority of which relates to an unused capital loss generated in the fourth quarter of 2021.

At the end of both 2022 and 2021, U. S. Steel did not have any undistributed foreign earnings and profits for which U.S. deferred taxes have not been provided.

For further information on income taxes see Note 11 to the Consolidated Financial Statements.

Environmental remediation – U. S. Steel has been identified as a PRP at four sites under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) as of December 31, 2022. Of these, there are three sites where information requests have been received or there are other indications that U. S. Steel may be a PRP under CERCLA, but where sufficient information is not presently available to confirm the existence of liability or to make a reasonable estimate with respect to any potential liabilities. There are also nine additional sites where U. S. Steel may be liable for remediation costs in excess of $1 million under other environmental statutes, both federal and state, or where private parties are seeking to impose liability on U. S. Steel for remediation costs through discussions or litigation. At many of these sites, U. S. Steel is one of a number of parties involved and the total cost of remediation, as well as U. S. Steel’s share, is frequently dependent upon the outcome of ongoing investigations and remedial studies. U. S. Steel accrues for environmental remediation activities when the responsibility to remediate is probable and the amount of associated costs is reasonably determinable. As environmental remediation matters proceed toward ultimate resolution or as remediation obligations arise, charges in excess of those previously accrued may be required.

U. S. Steel's accrual for environmental liabilities for U.S. and international facilities as of December 31, 2022 and 2021 was $126 million and $158 million, respectively. These amounts exclude liabilities related to asset retirement obligations, disclosed in Note 19 to the Consolidated Financial Statements.

U. S. Steel is the subject of, or a party to, a number of pending or threatened legal actions, contingencies and commitments involving a variety of matters, including laws and regulations relating to the environment. The ultimate resolution of these contingencies could, individually or in the aggregate, be material to the Consolidated Financial Statements.

For discussion of relevant environmental items, see “Part I. Item 3. Legal Proceedings—Environmental Proceedings.”

Segments

U. S. Steel has four reportable segments: North American Flat-Rolled, Mini Mill, USSE and Tubular Products. For further description of segment operations and information see Item 1 Segments and Note 4 to the Consolidated Financial Statements, respectively.

(b) Foreign currency translation effects.
(c) Primarily consists of sales of raw material and coke making by-products
(d) Mini Mill segment added after January 15, 2021 with the purchase of the remaining equity interest in BRS.

Net sales for the twelve months ended December 31, 2022 compared to the same period in 2021 were $21,065 million and $20,275 million, respectively.

•For the Flat-Rolled segment the increase in sales primarily resulted from higher average realized prices ($89 per ton) primarily from higher value-added products, partially offset by decreased shipments (645 thousand tons) across most products.

•For the Mini Mill segment the decrease in sales primarily resulted from lower average realized prices ($180 per ton) primarily from lower value-added products partially offset by increased shipments (57 thousand tons), including the partial period of the Company's controlling interest in Big River Steel in January of 2021.

•For the USSE segment the consistent sales primarily resulted from higher average realized prices ($124 per net ton) across most products, offset by decreased shipments (543 thousand tons) across most products.

•For the Tubular segment the increase in sales primarily resulted from higher average realized prices ($1,282 per net ton) and increased shipments (79 thousand tons).

Operating Expenses

Union profit-sharing costs


	Year Ended December 31,
(Dollars in millions)	2022		2021
Allocated to segment results	$	442	$	430

The amounts above represent profit-sharing amounts paid to active USW-represented employees and are included in cost of sales on the Consolidated Statement of Operations.

Profit-based amounts are calculated and paid on a quarterly basis as a percentage of consolidated earnings (loss) before interest and income taxes based on 7.5 percent of profit between $10 and $50 per ton and 15 percent of profit above $50 per ton. There were no changes to the calculation of profit-based amounts in the 2022 Labor Agreements.

Net periodic pension and other benefits costs

Pension and other benefit costs (other than service cost) are reflected within net interest and other financial costs and the service cost component is reflected within cost of sales in the Consolidated Statements of Operations.

Defined benefit and multiemployer pension plan costs included in cost of sales totaled $119 million in 2022 and $128 million in 2021.

Other benefit service cost included in cost of sales totaled $9 million in 2022 and $11 million in 2021.

Costs related to defined contribution plans totaled $47 million in 2022 and $45 million in 2021.

Selling, general and administrative expenses

Selling, general and administrative expenses were consistent for the years ended December 31, 2022 and December 31, 2021 at $422 million and $426 million, respectively.

Operating configuration adjustments

The Company adjusted its operating configuration in response to global overcapacity, unfair trade practices, market conditions and decreased customer demand by indefinitely and temporarily idling certain of its facilities. U. S. Steel will continue to adjust its operating configuration in order to ensure its order book and production footprint are balanced.

Idled Operations

In the second half of 2022, we took actions to adjust our footprint by temporarily idling certain operations to better align production with market conditions. The operations that were idled in the second half of 2022 and remained idled as of December 31, 2022, along with their carrying values included:

•Blast furnace #8 at Gary Works, $30 million

•Blast furnace #3 at Mon Valley Works, $45 million (restarted in January 2023)

•Blast furnace #2 at USSE, $25 million (restarted in January 2023)

The following operations were initially idled in 2020 and remained idle as of December 31, 2022. These facilities and their respective carrying values as of December 31, 2022 included:

•Blast Furnace A at Granite City Works, $55 million

•Lone Star Tubular Operations, $5 million

•Lorain Tubular Operations, $60 million

In the fourth quarter of 2022, U. S. Steel indefinitely idled the majority of the tin mill operations at Gary Works. This included the Tin Line #5, which was previously temporarily idled in the third quarter of 2022, and the Tin Line #6 indefinitely idled the fourth quarter of 2022. As of December 31, 2022, the carrying value of the indefinitely idled tin mill operations assets at Gary Works is $80 million.

At Great Lakes Works, the Company permanently idled the steelmaking operations in 2021 and ironmaking operations in 2022 which resulted in non-cash impairments of $128 million and $151 million, respectively. The coil finishing process at Great Lakes Works continues to operate and remains a component of the Company's operating plans.

Depreciation, depletion and amortization

Depreciation, depletion and amortization expenses were $791 million in both years ended December 31, 2022 and December 31, 2021.

Earnings from investees

Earnings from investees were $243 million in 2022 versus earnings from investees of $170 million in 2021. The increase in 2022 from the prior year is primarily due to current year earnings from our PRO-TEC joint venture from higher realized prices.

Restructuring and Other Charges

During 2022, the Company recorded restructuring and other charges of $48 million, which consists of charges of $30 million related to the planned disposition of a component within the Flat-Rolled segment, severance-related charges at domestic facilities of $4 million, charges under the Company's voluntary retirement programs at U. S. Steel Košice (USSK) of $23 million and a $9 million favorable adjustment to the expected exit costs of indefinitely idled facilities.

Charges for restructuring and ongoing cost reduction initiatives are recorded in the period U. S. Steel commits to a restructuring or cost reduction plan, or executes specific actions contemplated by the plan and all criteria for liability recognition have been met. Charges related to restructuring and cost reductions are reported in Restructuring and other charges in the Consolidated Statements of Operations.

Income Tax

The income tax expense for the year ended December 31, 2022 was $735 million compared to an income tax expense of $170 million in 2021. The change from the prior year period was primarily due to the tax benefit in the prior year period resulting from the release of the valuation allowance on domestic deferred tax assets.

In the third quarter of 2022, Pennsylvania House Bill 1342 was enacted, which in part phased in a corporate net income tax (CNIT) rate reduction over nine years. The CNIT rate for the 2022 tax year is 9.99%. The CNIT rate will be reduced to 8.99% for the 2023 tax year. Starting with the 2024 tax year, the rate is reduced by 0.5% annually until it reaches 4.99% for the 2031 tax year and each year thereafter. The Company assessed the impact of the law change and recorded an additional expense for it of $13 million in 2022 on its Consolidated Financial Statements.

On August 16, 2022, H.R. 5376 (commonly called the Inflation Reduction Act of 2022) was signed into law, which, among other things, implemented a corporate alternative minimum tax (CAMT) of 15 percent on book income of certain large corporations. The CAMT imposes a minimum tax on net income adjusted for certain items prescribed by the legislation and is effective for tax years beginning after December 31, 2022. Although management is currently assessing the impact of the law change and awaiting guidance from the Department of Treasury, the Company anticipates being subject to the new CAMT but does not believe that it will have a material impact on its Consolidated Financial Statements.

For further information on income taxes see Note 11 to the Consolidated Financial Statements.

Net earnings attributable to U. S. Steel

Net earnings attributable to U. S. Steel in 2022 was $2,524 million compared to net earnings of $4,174 million in 2021. The changes primarily reflected the factors discussed above.

Liquidity and Capital Resources

Cash Flows and Capital Requirements

Net Cash Provided by Operating Activities

Net cash provided by operating activities was $3,505 million in 2022 compared to $4,090 million in 2021. The decrease in 2022 compared to 2021 was primarily due to decreased net earnings, losses on debt extinguishments and income taxes and pension and other post-retirement benefits payables, partially offset by changes in working capital, deferred taxes payable and gains on sale of assets. Changes in working capital can vary significantly depending on factors such as the timing of inventory production and purchases, which is affected by the length of our business cycles as well as our captive raw materials position, customer payments of accounts receivable and payments to vendors in the regular course of business.

Our cash conversion cycle increased by 6 days in the fourth quarter of 2022 from the fourth quarter of 2021 as shown below:


Cash Conversion Cycle	2022			2021
	$ millions		Days	$ millions		Days
Accounts receivable, net (a)	$	1,634	39	$	2,089	37

+ Inventories (b)	$	2,359	60	$	2,210	51

- Accounts Payable and Other Accrued Liabilities (c)	$	2,831	70	$	2,684	65

= Cash Conversion Cycle (d)			29			23

(a) Calculated as Average Accounts Receivable, net divided by total Net Sales multiplied by the number of days in the period.

(b) Calculated as Average Inventory divided by total Cost of Sales multiplied by the number of days in the period.

(c) Calculated as Average Accounts Payable and Other Accrued Liabilities less bank checks outstanding and other current liabilities divided by total Cost of Sales multiplied by the number of days in the period.

(d) Calculated as Accounts Receivable Days plus Inventory Days less Accounts Payable Days.

The cash conversion cycle is a non-GAAP financial measure. We believe the cash conversion cycle is a useful measure in providing investors with information regarding our cash management performance and is a widely accepted measure of working capital management efficiency. The cash conversion cycle should not be considered in isolation or as an alternative to other GAAP metrics as an indicator of performance.

The LIFO inventory method is the predominant method of inventory costing for our Flat-Rolled and Tubular segments. The first-in, first-out FIFO and moving average methods are the predominant inventory costing methods for our Mini Mill segment and the

Table of Contents

FIFO method is the predominant inventory costing method for our USSE segment. In the U.S., management monitors the inventory realizability by comparing the LIFO cost of inventory with the replacement cost of inventory. To the extent the replacement cost (i.e., market value) of inventory is lower than the LIFO cost of inventory, management will write the inventory down. As of December 31, 2022 and 2021, the replacement cost of the LIFO inventory was higher by approximately $1,154 million and $896 million, respectively.

Net cash provided by operating activities for 2022 and 2021 reflects employee benefits payments as shown in the following table.


Benefits Payments for Employees	Year Ended December 31,

Net Cash Used in Investing Activities

Net cash used in investing activities was $1,679 million in 2022 compared to $840 million in 2021. The increase in net cash used in investing activities was primarily due to increased capital expenditures (discussed in more detail below) and receipt of $627 million in the prior year for the sale of Transtar, partially offset by the payment of $625 million in the prior year period for the purchase of the remaining equity interest in Big River Steel and proceeds of $54 million in the current year period from government grants.

Capital expenditures in 2022 were $1,769 million compared to $863 million in 2021.

Total capital expenditures for 2022 were $1,769 million. Flat-Rolled capital expenditures were $503 million and included spending for the construction of a pig iron facility at Gary Works, Keetac DR-grade pellet capability, as well as mining equipment, infrastructure and environmental projects across the Flat-Rolled footprint. Mini Mill capital expenditures were $1,159 million and included $780 million, exclusive of the air separation unit, for the new Big River 2 (BR2) 3 million ton per year facility being built in Osceola, Arkansas, as well as spending for the new continuous galvanizing line (CGL) and non-grain oriented electrical steel facility being built at the existing Big River Steel facility. USSE capital expenditures were $90 million and included spending for the blast furnace stoves, 5-stand control system upgrades, wastewater quality improvements, rail bridge upgrades and various other projects. Tubular capital expenditures were $17 million and included spending to support steelmaking, infrastructure and environmental projects within the Tubular footprint.

Net Cash used in Financing Activities

Net cash used in financing activities was $868 million for the twelve months ended December 31, 2022 compared to net cash used by financing activities of $2,747 million for the same period in 2021. The period over period decrease in cash used in financing activities was primarily due to higher debt repayments made during the prior year, partially offset by the cash received from common stock issuances in the prior year period and repurchases of common stock made in the current year period.

Debt Financing

In 2022, U. S. Steel made payments of debt and redemption premiums of approximately $382 million. The following is a summary of debt repayments for our Senior Secured Notes, Senior Notes and other debt obligations made during the twelve months ended December 31, 2022:

(a) There were redemption discounts and unamortized debt issuance cost write-offs of $6 million and $1 million , respectively, included in (gain) loss on debt extinguishment on the Consolidated Statement of Operations related to the repayment.

(b) During the twelve months ended December 31, 2022, there were no redemption premiums paid and a net loss of $4 million for the write-off of unamortized discounts and debt issuance costs, included in (gain) loss on debt extinguishment on the Consolidated Statement of Operations, as a result of these debt repayments.

Certain of our credit facilities, including the Credit Facility Agreement, the Big River Steel ABL Facility, the USSK Credit Agreement and the Export Credit Agreement, contain standard terms and conditions including customary material adverse change clauses. If a material adverse change was to occur, our ability to fund future operating and capital requirements could be negatively impacted. The €300 million USSK Credit Agreement contains certain USSK specific financial covenants. There are currently no amounts outstanding under the facility. The USSK Credit Agreement requires USSK to maintain a net debt to earnings before interest, taxes, depreciation and amortization (EBITDA) ratio of less than 3.50:1 for the rolling twelve months ending June 30, 2023. The Company has determined that it may not be able to comply with this covenant at June 30, 2023 based on the currently forecasted EBITDA for the twelve-month period ending June 30, 2023. This could partially or fully limit USSK's ability to borrow under the USSK Credit Agreement. Any amendment or waiver may lead to additional lender protections, including a reduction of loan commitments or less favorable terms, and there can be no assurance that USSK can obtain waivers or amendments in timely fashion, or on acceptable terms or at all. The Company believes that USSK will have adequate cash on hand as of June 30, 2023, and will not need to borrow under the USSK Credit Agreement.

We assumed additional indebtedness in connection with the acquisition of Big River Steel on January 15, 2021. Most of Big River Steel’s prior financing arrangements were secured transactions, with many of the assets of BRS Intermediate Holdings LLC, Big River Steel LLC and BRS Finance Corp. secured as collateral. Until we repay, refinance or otherwise amend the debt arrangements, we remain subject to the restrictive terms of the indentures.

We use surety bonds, trusts and letters of credit to provide financial assurance for certain transactions and business activities. The use of some forms of financial assurance and cash collateral have a negative impact on liquidity. U. S. Steel has committed $178 million of liquidity sources for financial assurance purposes as of December 31, 2022. Increases in certain of these commitments which use collateral are reflected within cash, cash equivalents and restricted cash on the Consolidated Statement of Cash Flows.

The maximum guarantees of the indebtedness of unconsolidated entities of U. S. Steel totaled $7 million at December 31, 2022. If any default related to the guaranteed indebtedness occurs, U. S. Steel has access to its interest in the assets of the investees to reduce its potential losses under the guarantees.

We may from time to time seek to retire or repurchase our outstanding long-term debt through open market purchases, privately negotiated transactions, exchange transactions, redemptions or otherwise. Such purchases or exchanges, if any, will depend on prevailing market conditions, our liquidity requirements and other factors and may be commenced or suspended at any time. The amounts involved may be material. See Note 17 to the Consolidated Financial Statements for further details regarding U. S. Steel's debt.

Share Repurchases

In the third quarter of 2022, following the completion of the previously authorized $800 million share repurchase programs, the Board of Directors authorized a new share repurchase program that allows for the repurchase of up to $500 million of its outstanding common stock from time to time in the open market or privately negotiated transactions at the discretion of management. The Company's share repurchase program does not obligate it to acquire any specific number of shares. Common stock repurchased under our share repurchase programs totaled 37.6 million shares and approximately $849 million in the twelve months ended December 31, 2022. See Note 27 to the Consolidated Financial Statements, “Common Stock Issued and Repurchased” for further details.

Capital Requirements

Our major cash requirements in 2023 are expected to be for capital expenditures, including strategic priorities, employee benefits and operating costs, which includes purchases of raw materials. We ended 2022 with $3,504 million of cash and cash

Table of Contents

equivalents and $5,925 million of total liquidity. Available cash is left on deposit with financial institutions or invested in highly liquid securities with parties we believe to be creditworthy.

Capital expenditures for 2023 are expected to total approximately $2.5 billion which are focused largely on strategic projects, as we work to increase our capacity and raw material and finishing capabilities by focusing on investments in our Mini Mill and Flat-Rolled segments.

U. S. Steel’s contractual commitments to acquire property, plant and equipment at December 31, 2022 totaled $2,235 million.

Liquidity

The following table summarizes U. S. Steel’s liquidity as of December 31, 2022:


(Dollars in millions)
Cash and cash equivalents	$	3,504
Amount available under Credit Facility Agreement	1,746
Amount available under Big River Steel - Revolving Line of Credit	350
Amounts available under USSK Credit Agreement and USSK Credit Facility	325
Total estimated liquidity	$	5,925

As of December 31, 2022, $405 million of the total cash and cash equivalents was held by our foreign subsidiaries. Substantially all of the liquidity attributable to our foreign subsidiaries can be accessed without the imposition of income taxes as a result of the election effective December 31, 2013 to liquidate for U.S. income tax purposes a foreign subsidiary that holds most of our international operations.

We expect that our estimated liquidity requirements will consist primarily of our 2023 planned strategic capital expenditures, working capital requirements, interest expense, and operating costs and employee benefits for our operations after taking into account the footprint actions and cost reductions at our plants and headquarters. Our available liquidity at December 31, 2022 consists principally of our cash and cash equivalents and available borrowings under the Credit Facility Agreement, Big River Steel ABL Facility, USSK Credit Agreement and the USSK Credit Facility. Management continues to evaluate market conditions in our industry and our global liquidity position, and may consider additional actions to further strengthen our balance sheet and optimize liquidity, including but not limited to the repayment or refinancing of outstanding debt and the incurrence of additional debt to opportunistically finance strategic projects. The Company may also return excess liquidity to shareholders through share repurchases and dividends from time to time.

U. S. Steel management believes that U. S. Steel’s liquidity will be adequate to satisfy our obligations for the foreseeable future, including obligations to complete currently authorized capital spending programs. Future requirements for U. S. Steel’s business needs, including the funding of acquisitions and capital expenditures, scheduled debt maturities, repurchase of debt, share buybacks, dividends, contributions to employee benefit plans and any amounts that may ultimately be paid in connection with contingencies, are expected to be funded by a combination of internally generated funds (including asset sales), proceeds from the sale of stock, borrowings, refinancings and other external financing sources. The following table summarizes the Company's contractual obligations at December 31, 2022, and the effect such obligations are expected to have on our liquidity and cash flows in future periods.

(d) See Note 26 to the Consolidated Financial Statements.

(e) While it is difficult to make a prediction of cash requirements beyond the term of the 2022 Labor Agreements with the USW, which expire on September 1, 2026, projected amounts shown through 2027 assume the contribution rate per hour included in the 2022 Labor Agreements of $4.00 per hour worked.

(f) The amounts reflect corporate cash outlays for expected benefit payments to be paid by the Company. (See Note 18 to the Consolidated Financial Statements.) The accuracy of this forecast of future cash flows depends on future medical health care escalation rates and restrictions related to our trusts for retiree healthcare and life insurance (VEBA) that impact the timing of the use of trust assets. Projected amounts have been reduced to reflect withdrawals from the USW VEBA trust available under its agreements with the USW. Due to these factors, it is not possible to reliably estimate cash requirements beyond five years and actual amounts experienced may differ significantly from those shown.

Off-Balance Sheet Arrangements

U. S. Steel has invested in several joint ventures that are reported as equity investments. Several of these investments involved a transfer of assets in exchange for an equity interest. U. S. Steel has supply arrangements with several of these joint ventures.

U. S. Steel’s other off-balance sheet arrangements include guarantees, indemnifications, unconditional purchase obligations, surety bonds, trusts and letters of credit disclosed in Note 26 to the Consolidated Financial Statements.

U. S. Steel’s environmental capital expenditures accounted for 2 percent of total capital expenditures in 2022 and 3 percent in 2021 and 6 percent in 2020.

Environmental compliance expenditures represented 2 percent of U. S. Steel's total costs and expenses in 2022, 2021 and 2020. Remediation spending during 2020 through 2022 was mainly related to remediation activities at former and present operating locations.

The following table shows activity with respect to environmental remediation liabilities for the years ended December 31, 2022 and December 31, 2021. These amounts exclude liabilities related to asset retirement obligations accounted for in accordance with ASC Topic 410. See Note 19 to the Consolidated Financial Statements.

New or expanded environmental requirements, which could increase U. S. Steel’s environmental costs, may arise in the future. U. S. Steel intends to comply with all legal requirements regarding the environment, but since many of them are not fixed or presently determinable (even under existing legislation) and may be affected by future legislation, it is not possible to predict accurately the ultimate cost of compliance, including remediation costs which may be incurred and penalties which may be imposed. U. S. Steel’s environmental capital expenditures are expected to be approximately $84 million in 2023, $15 million of which is related to projects at USSE. U. S. Steel's environmental expenditures for 2023 for operating and maintenance and for remediation projects are expected to be approximately $232 million and $42 million, respectively, of which approximately $13 million and $5 million for operating and maintenance and remediation, respectively, is related to USSE. Although, the outcome of pending environmental matters is not estimable at this time, it is reasonably possible that U. S. Steel's environmental capital and operating and maintenance expenditures could materially increase as a result of the future resolution of these matters. Predictions of future environmental expenditures beyond 2023 can only be broad-based estimates, which have varied, and will continue to vary, due to the ongoing evolution of specific regulatory requirements, the possible imposition of more stringent requirements and the availability of new technologies to remediate sites, among other factors.

Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

U. S. Steel is exposed to certain risks related to its ongoing business operations, including financial, market, political, and economic risks. The following discussion provides information regarding U. S. Steel’s exposure to the risks of changing foreign currency exchange rates, commodity prices and interest rates.

U. S. Steel may enter into derivative financial instrument transactions in order to manage or reduce these market risks. The use of derivative instruments is subject to our corporate governance policies. These instruments are used solely to mitigate market exposure and are not used for trading or speculative purposes.

U. S. Steel may elect to use hedge accounting for certain commodity or currency transactions. For those transactions, the impact of the hedging instrument will be recognized in other comprehensive income until the transaction is settled. Once the transaction is settled, the effect of the hedged item will be recognized in income. For further information regarding derivative instruments see Notes 1 and 16 to the Consolidated Financial Statements.

Foreign Currency Exchange Rate Risk

U. S. Steel is subject to the risk of price fluctuations due to the effects of exchange rates on revenues and operating costs, firm commitments for capital expenditures and existing assets or liabilities denominated in currencies other than the U.S. dollar, particularly the euro. U. S. Steel historically has made limited use of forward currency contracts to manage exposure to certain currency price fluctuations. U. S. Steel elected cash flow hedge accounting for foreign exchange forwards and had no material open forward exchange contracts that were subject to mark-to-market accounting as of December 31, 2022.

The fair value of our derivatives is determined using Level 2 inputs, which are defined as “significant other observable” inputs. The inputs used include quotes from counterparties that are corroborated with market sources.

Volatility in the foreign currency markets could have significant implications for U. S. Steel as a result of foreign currency transaction effects. Future foreign currency impacts will depend upon changes in currencies and the extent to which we engage in derivatives transactions. For additional information on U. S. Steel’s foreign currency exchange activity, see Note 16 to the Consolidated Financial Statements.

Commodity Price Risk and Related Risks

In the normal course of our business, U. S. Steel is exposed to market risk or price fluctuations related to the purchase, production or sale of steel products. U. S. Steel is also exposed to price risk related to the purchase, production or sale of coal, coke, natural gas, steel scrap, iron ore and pellets, and zinc, tin and other nonferrous metals used as raw materials. U. S. Steel is also subject to market price risk for the purchase of a portion of its electricity at certain facilities. See Note 16 to the Consolidated Financial Statements for further details on U. S. Steel’s derivatives.

U. S. Steel’s market risk strategy has generally been to obtain competitive prices for our products and services and allow operating results to reflect market price movements dictated by supply and demand; however, from time to time U. S. Steel has made forward physical purchases to manage exposure to price risk related to the purchases of natural gas and certain non-ferrous metals used in the production process. As of December 31, 2022, U. S. Steel, through U. S. Steel Europe, had $12 million forward buy contracts for zinc. There were no forward buy contracts for natural gas or any of the other significant raw materials used in the domestic production process.

Interest Rate Risk

U. S. Steel is subject to the effects of interest rate fluctuations on the fair value of certain of our non-derivative financial instruments. A sensitivity analysis of the projected incremental effect of a hypothetical 10 percent increase/decrease in year-end 2022 and 2021 interest rates on the fair value of U. S. Steel’s non-derivative financial instruments is provided in the following table:


(Dollars in millions)	2022				2021
Non-Derivative Financial Instruments(a)	Fair Value(b)		Change in Fair Value(c)		Fair Value(b)		Change in Fair Value(c)
Financial liabilities:
Debt(d)(e)	$	3,815	$	116	$	4,379	$	143

(a)Fair values of cash and cash equivalents, current accounts and notes receivable, accounts payable, bank checks outstanding and accrued interest approximate carrying value and are relatively insensitive to changes in interest rates due to the short-term maturity of the instruments. Accordingly, these instruments are excluded from the table.

(b)See Note 20 to the Consolidated Financial Statements for carrying value of instruments.

(c)Reflects, by class of financial instrument, the estimated incremental effect of a hypothetical 10 percent change in interest rates at December 31, 2022, and 2021, on the fair value of U. S. Steel’s non-derivative financial instruments. For financial liabilities, this assumes a 10 percent decrease in the weighted average yield to maturity of U. S. Steel’s long-term debt at December 31, 2022 and December 31, 2021.

(d)Excludes finance lease obligations.

(e)Fair value was determined using Level 2 inputs which were derived from quoted market prices and is based on the yield on public debt where available or current borrowing rates available for financings with similar terms and maturities.

U. S. Steel’s sensitivity to interest rate declines and corresponding increases in the fair value of our debt portfolio would unfavorably affect our results and cash flows only to the extent that we elected to repurchase or otherwise retire all or a portion of our fixed-rate debt portfolio at prices above carrying value.

MANAGEMENT’S REPORT TO STOCKHOLDERS

February 3, 2023

To the Stockholders of United States Steel Corporation:

Financial Statements and Practices

The accompanying consolidated financial statements of United States Steel Corporation are the responsibility of and have been prepared by United States Steel Corporation in conformity with accounting principles generally accepted in the United States of America. They necessarily include some amounts that are based on our best judgments and estimates. United States Steel Corporation’s financial information displayed in other sections of this report is consistent with these financial statements.

United States Steel Corporation seeks to assure the objectivity and integrity of its financial records by careful selection of its managers, by organizational arrangements that provide an appropriate division of responsibility and by communication programs aimed at assuring that its policies, procedures and methods are understood throughout the organization.

United States Steel Corporation has a comprehensive, formalized system of internal controls designed to provide reasonable assurance that assets are safeguarded, that financial records are reliable and that information required to be disclosed in reports filed with or submitted to the Securities and Exchange Commission is recorded, processed, summarized and reported within the required time limits. Appropriate management monitors the system for compliance and evaluates it for effectiveness, and the independent registered public accounting firm measures its effectiveness and recommends possible improvements thereto.

The Board of Directors exercises its oversight role in the area of financial reporting and internal control over financial reporting through its Audit Committee. This committee, composed solely of independent directors, regularly meets (jointly and separately) with the independent registered public accounting firm, management, internal audit and other executives to monitor the proper discharge by each of their responsibilities relative to internal control over financial reporting and United States Steel Corporation’s financial statements.

Internal Control Over Financial Reporting

United States Steel Corporation’s management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Exchange Act Rule 13a-15(f). Under the supervision and with the participation of United States Steel Corporation’s management, including the Chief Executive Officer and Chief Financial Officer, United States Steel Corporation conducted an evaluation of the effectiveness of its internal control over financial reporting based on the framework in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Based on this evaluation, United States Steel Corporation’s management concluded that United States Steel Corporation’s internal control over financial reporting was effective as of December 31, 2022.

The effectiveness of United States Steel Corporation’s internal control over financial reporting as of December 31, 2022, has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which is included herein.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of United States Steel Corporation

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of United States Steel Corporation and its subsidiaries (the “Company”) as of December 31, 2022 and 2021, and the related consolidated statements of operations, of comprehensive income (loss), of stockholders’ equity and of cash flows for each of the three years in the period ended December 31, 2022, including the related notes and financial statement schedule listed in the index appearing under Item 15(a)(2) (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2022 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report to Stockholders on Internal Control Over Financial Reporting. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or

Table of Contents

disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Goodwill Impairment Test – Mini Mill Reporting Unit

As described in Notes 1 and 14 to the consolidated financial statements, the Company’s consolidated goodwill balance was $920 million as of December 31, 2022, which included $916 million relating to the Mini Mill reporting unit. Goodwill is deemed to have an indefinite life and is not amortized, but is subject to impairment testing annually, or more frequently if events or changes in circumstances indicate the asset might be impaired. Management performs an annual goodwill impairment test as of October 1 and monitors for interim triggering events on an ongoing basis. Fair value is determined by management using an income approach based on a discounted five year forecasted cash flow including a terminal value. The assumptions about future cash flows and growth rates are based on the respective reporting unit’s long-term forecast. The Mini Mill reporting unit’s discount rate is a significant assumption and is a risk-adjusted weighted average cost of capital, which management believes approximates the rate from a market participant’s perspective.

The principal considerations for our determination that performing procedures relating to the goodwill impairment test of the Mini Mill reporting unit is a critical audit matter are (i) the significant judgment by management when developing the fair value estimate of the Mini Mill reporting unit; (ii) a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating management’s significant assumption related to the discount rate; and (iii) the audit effort involved the use of professionals with specialized skill and knowledge.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to management’s goodwill impairment test, including controls over the valuation of the Mini Mill reporting unit. These procedures also included, among others (i) testing management’s process for developing the fair value estimate; (ii) evaluating the appropriateness of the discounted cash flow model; (iii) testing the completeness and accuracy of underlying data used in the discounted cash flow model; and (iv) evaluating the reasonableness of the significant assumption used by management related to the discount rate. Evaluating management’s assumption related to the discount rate involved evaluating whether the significant assumption used by management was reasonable considering the consistency with external market and industry data. Professionals with specialized skill and knowledge were used to assist in evaluating (i) the appropriateness of the Company’s discounted cash flow model and (ii) the reasonableness of the discount rate assumption.

Table of Contents

1. Nature of Business and Significant Accounting Policies

Nature of Business

U. S. Steel produces and sells steel products, including flat-rolled and tubular products, in North America and Europe. Operations in the United States also include iron ore and coke production facilities and real estate operations. Operations in Europe also include coke production facilities.

Significant Accounting Policies

Principles applied in consolidation

These financial statements include the accounts of U. S. Steel and its majority-owned subsidiaries. Additionally, variable interest entities for which U. S. Steel is the primary beneficiary are included in the Consolidated Financial Statements, and their impacts are either partially or completely offset by noncontrolling interests. Intercompany accounts, transactions and profits have been eliminated in consolidation.

Investments in entities over which U. S. Steel has significant influence are accounted for using the equity method of accounting and are carried at U. S. Steel’s share of net assets plus loans, advances and our share of earnings less distributions.

Earnings or loss from investees includes U. S. Steel’s share of earnings or loss from equity method investments (and any amortization of basis differences), which are generally recorded a month in arrears.

Use of estimates

Generally accepted accounting principles require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at year-end and the reported amounts of revenues and expenses during the year. Significant items subject to such estimates and assumptions include the carrying value of property, plant and equipment; intangible assets; the fair value of assets or liabilities acquired in a business combination; valuation allowances for receivables, inventories and deferred income tax assets and liabilities; environmental liabilities; liabilities for potential tax deficiencies; potential litigation claims and settlements; assets and obligations related to employee benefits; put and call option and contingent forward purchase commitment assets and liabilities; and restructuring and other charges. Actual results could differ materially from the estimates and assumptions used.

The preparation of the financial statements includes an assessment of certain accounting matters using all available information including consideration of forecasted financial information in context with other information reasonably available to us. However, our future assessment of current expectations could result in material impacts to our consolidated financial statements in future reporting periods. All such adjustments are of a normal recurring nature unless disclosed otherwise.

Sales recognition

Sales are recognized when U. S. Steel's performance obligations are satisfied. Generally, U. S. Steel’s performance obligations are satisfied, control of our products is transferred, and revenue is recognized at a single point in time, when title transfers to our customer for product shipped or when services are provided. Revenues are recorded net of any sales incentives. Shipping and other transportation costs charged to customers are treated as fulfillment activities and are recorded in both revenue and cost of sales at the time control is transferred to the customer. See Note 6 for further details on U. S. Steel’s revenue.

Inventories

Inventories are carried at the lower of cost or net realizable value. Fixed costs related to abnormal production capacity are expensed in the period incurred rather than capitalized into inventory.

LIFO is the predominant method of inventory costing for inventories held by the Flat-Rolled and Tubular segments. The Mini Mill segment uses a moving average costing method to account for semi-finished and finished products and FIFO to account for raw materials. FIFO is the predominant method used by the USSE segment. The LIFO method of inventory costing was used on 43 percent and 46 percent of consolidated inventories at December 31, 2022, and 2021, respectively.

Derivative instruments

From time to time, U. S. Steel may use fixed price forward physical purchase contracts to partially manage our exposure to price risk. Generally, forward physical purchase contracts qualify for the normal purchase normal sales exclusion in Accounting Standards Codification (ASC) 815, Derivatives and Hedging, and are not subject to mark-to-market accounting. U. S. Steel also uses derivatives such as commodity-based financial swaps and foreign currency exchange forward contracts to manage its exposure to purchase and sale price fluctuations and foreign currency exchange rate risk. The USSE and Flat-Rolled segments elect hedge accounting for some of their derivatives. Under hedge accounting, fluctuations in the value of the derivative are recognized in Accumulated other comprehensive (loss) income (AOCI) until

Table of Contents

the associated underlying is recognized in earnings. When the associated underlying is recognized in earnings, the value of the derivative is reclassified to earnings from AOCI. The Mini Mill segment has not elected hedge accounting. Therefore, the changes in fair value of the Mini Mill segment's foreign exchange forwards, as well as fair value changes for other derivatives where hedge accounting has not been elected, are recognized immediately in earnings. In accordance with the guidance in ASC Topic 820 on fair value measurements and disclosures, the fair value of our foreign exchange forwards, commodity purchase swaps and sales swaps was determined using Level 2 inputs, which are defined as "significant other observable" inputs. The inputs used are from market sources that aggregate data based upon market transactions. See Note 16 for further details on U. S. Steel’s derivatives.

Property, plant and equipment

Property, plant and equipment is carried at cost less accumulated depreciation and is depreciated on a straight-line basis over the estimated useful lives of the assets.

Depletion of mineral properties is based on rates which are expected to amortize cost over the estimated tonnage of minerals to be removed.

When property, plant and equipment is sold or otherwise disposed of, any gains or losses are reflected in income. If a loss on disposal is expected, such losses are recognized when the assets are reclassified as assets held for sale or when impaired as part of an asset group’s impairment.

Asset Impairment

U. S. Steel evaluates impairment of its property, plant and equipment whenever circumstances indicate that the carrying value may not be recoverable. We evaluate the impairment of long-lived assets at the asset group level. Our asset groups are flat-rolled, mini mill, welded tubular, seamless tubular and USSE. Asset impairments are recognized when the carrying value of an asset group exceeds its recoverable amount as determined by the asset group's aggregate projected undiscounted cash flows.

In the second quarter 2022, the Company recognized charges of approximately $151 million for the write-off of the blast furnaces and related fixed assets for the permanent idling of the iron making process at the Company's Great Lakes Works facility, which had been idled on an indefinite basis during 2020. The coil finishing process at Great Lakes Works continues to operate and remains a component of the Company's operating plans.

In December 2021, the Company permanently idled the steel making process at Great Lakes Works, which had been idled on an indefinite basis during 2020. As a result of this decision, the Company recognized charges of approximately $128 million for the write-off of the BOP, steel casting and hot strip mill related fixed assets. In addition, in October 2021, equipment at Gary Works related to steel production intended for petroleum conveying pipe were written-off resulting in a charge of approximately $88 million.

In May 2019, U. S. Steel announced that it planned to construct a new endless casting and rolling facility at its Edgar Thomson Plant in Braddock, Pennsylvania, and a cogeneration facility at its Clairton Plant in Clairton, Pennsylvania, both part of the Company's Mon Valley Works. The Company purchased certain equipment for this project before delaying groundbreaking in March 2020 in response to COVID-19. In April 2021, the Company determined not to pursue this project, re-evaluated the use of the already purchased equipment, and subsequently transferred suitable equipment to the Mini Mill segment to be used on the planned, three-million-ton mini mill flat-rolled facility to be constructed. Total impairments of $56 million were recognized for this project in 2021.

For the period ended March 31, 2020, the steep decline in oil prices that resulted from market oversupply and declining demand was considered a triggering event for the welded tubular and seamless tubular asset groups. A quantitative analysis was completed for both asset groups and a $263 million impairment, consisting of an impairment of $196 million for property, plant and equipment and $67 million for intangible assets was recorded for the welded tubular asset group while no impairment was indicated for the seamless tubular asset group. There were no other triggering events that required an impairment evaluation of our long-lived asset groups during the years-ended December 31, 2022 and 2021.

Table of Contents

Goodwill and identifiable intangible assets

Goodwill represents the excess of the cost over the fair value of acquired identifiable tangible and intangible assets and liabilities assumed from businesses acquired. Goodwill and intangible assets deemed to have indefinite lives are not amortized, but are subject to impairment testing annually, or more frequently if events or changes in circumstances indicate the asset might be impaired. We perform our annual goodwill impairment test as of October 1 and monitor for interim triggering events on an ongoing basis.

We review goodwill for impairment utilizing either a qualitative assessment or a quantitative goodwill impairment test. If we choose to perform a qualitative assessment and we determine that the fair value of the reporting unit more likely than not exceeds the carrying value, no further evaluation is necessary. For reporting units where we perform the quantitative goodwill impairment test, we compare the fair value of each reporting unit, which we primarily determine using an income approach based on the present value of discounted cash flows, to the respective carrying value, which includes goodwill. If the fair value of the reporting unit exceeds its carrying value, we do not consider the goodwill impaired. If the carrying value is higher than the fair value, we recognize the difference as an impairment loss.

Environmental remediation

Environmental expenditures are capitalized if the costs mitigate or prevent future contamination or if the costs improve existing assets’ environmental safety or efficiency. U. S. Steel provides for remediation costs and penalties when the responsibility to remediate is probable and the amount of associated costs is reasonably estimable. The timing of remediation accruals typically coincides with completion of studies defining the scope of work to be undertaken or when it is probable that a formal plan of action will be approved by the oversight agency. Remediation liabilities are accrued based on estimates of believed environmental exposure and are discounted if the amount and timing of the cash disbursements are readily determinable.

Asset retirement obligations

Asset retirement obligations (AROs) are initially recorded at fair value and are capitalized as part of the cost of the related long-lived asset and depreciated in accordance with U. S. Steel’s depreciation policies for property, plant and equipment. The fair value of the obligation is determined as the discounted value of expected future cash flows. Accretion expense is recorded each month to increase this discounted obligation over time. Certain AROs related to disposal costs of the majority of assets at our integrated steel facilities are not recorded because they have an indeterminate settlement date. These AROs will be initially recognized in the period in which sufficient information exists to estimate their fair value. See Note 19 for further details on U. S. Steel's AROs.

Pensions and other post-employment benefits

U. S. Steel has defined contribution or multiemployer arrangements for pension benefits for more than 80 percent of its employees in the United States and defined benefit pension plans covering the remaining employees. For hires before January 1, 2016, U. S. Steel has defined benefit retiree health care and life insurance plans (Other Benefits) that cover its represented employees in North America upon their retirement. Government-sponsored programs into which U. S. Steel

Table of Contents

makes required contributions cover U. S. Steel’s European employees. For more details regarding pension and other post-employment benefits see Note 18 of the Consolidated Financial Statements.

The pension and Other Benefits obligations and the related net periodic benefit costs are based on, among other things, assumptions regarding the discount rate, estimated return on plan assets, salary increases, the projected mortality of participants and the current level and future escalation of health care costs. Additionally, U. S. Steel recognizes an obligation to provide post-employment benefits for disability-related claims covering indemnity and medical payments for certain employees in North America. The obligation for these claims and the related periodic costs are measured using actuarial techniques and assumptions. Actuarial gains and losses occur when actual experience differs from any of the many assumptions used to value the benefit plans, or when assumptions change. For pension and Other Benefits, the Company recognizes into income on an annual basis a portion of unrecognized actuarial net gains or losses that exceed 10 percent of the larger of projected benefit obligations or plan assets (the corridor). These unrecognized amounts in excess of the corridor are amortized over the plan participants' average life expectancy or average future service, depending on the demographics of the plan. Unrecognized actuarial net gains and losses for disability-related claims are immediately recognized into income.

Deferred taxes

Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. The realization of deferred tax assets is assessed quarterly based on several interrelated factors. These factors include U. S. Steel’s expectation to generate sufficient future taxable income and the projected time period over which these deferred tax assets will be realized. U. S. Steel records a valuation allowance when necessary to reduce deferred tax assets to the amount that will more likely than not be realized. See Note 11 for further details of deferred taxes.

2. New Accounting Standards

In October 2021, the FASB issued Accounting Standards Update 2021-08, Accounting for Contract Assets and Contract Liabilities from Contracts with Customers (ASU 2021-08). ASU 2021-08 requires that an entity recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606, Revenue from Contracts with Customers. ASU 2021-08 is effective to public companies for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years, with early adoption of all amendments in the same period permitted. The Company will apply the guidance prescribed by ASU 2021-08 to business combinations, if any, that take place subsequent to the effective date.

In September 2022, the FASB issued Accounting Standards Update 2022-04, Disclosure of Supplier Finance Program Obligations (ASU 2022-04). ASU 2022-04 requires that an entity disclose certain information about supplier finance programs used in connection with the purchase of goods and services. ASU 2022-04 is effective for all entities with fiscal years beginning after December 15, 2022, and interim periods within those fiscal years, except for the amendment on roll forward information, which is effective for fiscal years beginning after December 15, 2023. Early adoption of all amendments is permitted. The Company will adopt the interim disclosure requirements as applicable during the first quarter 2023 and the annual disclosure requirements except for the annual rollforward in the 2023 Form 10-K. The Company will adopt the annual rollforward disclosure requirement in the 2024 Form 10-K.

3. Recently Adopted Accounting Standards

In August 2020, the FASB issued Accounting Standards Update 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (ASU 2020-06). ASU 2020-06 simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. ASU 2020-06 also requires entities to provide expanded disclosures about the terms and features of convertible instruments and amends certain guidance in ASC 260 on the computation of earnings per share (EPS) for convertible instruments and contracts on an entity’s own equity. The update requires entities to use the If-Converted Method for calculating diluted EPS, retiring the previous alternative calculation of the Treasury Stock Method for calculating diluted EPS for convertible instruments.

U. S. Steel has adopted this guidance using the modified retrospective implementation method as of January 1, 2022. The cumulative effect of the changes made to our consolidated January 1, 2022, balance sheet for the adoption of ASU 2020-06 was as follows:

Table of Contents


(in millions)	Balance as of December 31, 2021	Adjustments due to ASU 2020-06	Balance as of January 1, 2022
Consolidated Balance Sheet
Assets
Deferred income tax benefits	$32	$4	$36

Liabilities
Long-term debt, less unamortized discount and debt issuance costs	$3,863	$74	$3,937
Deferred income tax liabilities	$122	$(15)	$107

Equity
Additional paid-in capital	$5,199	$(78)	$5,121
Retained Earnings	$3,534	$22	$3,556

In November 2021, the FASB issued Accounting Standards Update 2021-10, Disclosures by Business Entities about Government Assistance (ASU 2021-10). ASU 2021-10 provides expanded disclosure requirements for business entities that account for a transaction with a government by applying a grant or contribution accounting model by analogy. The Company adopted this guidance effective January 1, 2022. The adoption of this guidance did not have a material impact on the Company's Consolidated Financial Statements.

In December 2019, the FASB issued Accounting Standards Update 2019-12, Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes (ASU 2019-12). ASU 2019-12 simplifies accounting for income taxes by removing certain exceptions from the general principles in Topic 740 including elimination of the exception to the incremental approach for intraperiod tax allocation when there is a loss from continuing operations and income or a gain from other items such as other comprehensive income. U. S. Steel adopted this guidance on January 1, 2021. The adoption of this guidance did not have a material impact on the Company's Consolidated Financial Statements.

In March 2020, the FASB issued Accounting Standards Update 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting (ASU 2020-04). ASU 2020-04 provides optional exceptions for applying generally accepted accounting principles to modifications of contracts, hedging relationships, and other transactions that reference LIBOR or another rate that will be discontinued by reference rate reform if certain criteria are met. The guidance was effective beginning on March 12, 2020 and the amendments were applied prospectively through December 31, 2022. U. S. Steel adopted this guidance during 2020. The adoption of this guidance did not have a material impact on the Company's Consolidated Financial Statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (ASU 2016-13), which adds an impairment model that is based on expected losses rather than incurred losses. U. S. Steel's significant financial instruments which are valued at cost are trade receivables (receivables). U. S. Steel's receivables carry standard industry terms and are categorized in two receivable pools, U.S. and USSE. Both pools use customer specific risk ratings based on customer financial metrics, past payment experience and other factors and qualitatively consider economic conditions to assess the level of allowance for doubtful accounts. USSE mitigates credit risk for approximately 76 percent of its receivables balance using credit insurance, letters of credit, bank guarantees, prepayments or other collateral. ASU 2016-13 was effective for public companies for fiscal years beginning after December 15, 2019, including interim reporting periods. U. S. Steel adopted this standard effective January 1, 2020. The impact of adoption was not material to the Consolidated Financial Statements.

4. Segment Information

U. S. Steel has four reportable segments: North American Flat-Rolled, Mini Mill, USSE and Tubular Products. The results of our real estate business, the previously held equity method investment in Big River Steel, and of our former railroad businesses are combined and disclosed in the Other category. The majority of U. S. Steel's customers are located in North America and Europe. No single customer accounted for more than 10 percent of gross annual revenues.

The Flat-Rolled segment includes the operating results of U. S. Steel’s integrated steel plants and equity investees in the United States involved in the production of slabs, strip mill plates, sheets and tin mill products, as well as all pig iron, iron ore and coke production facilities in the United States. These operations primarily serve North American customers in the service center, conversion, transportation (including automotive), construction, container and appliance and electrical markets.

The Mini Mill segment reflects the acquisition of Big River Steel after the purchase of the remaining equity interest on January 15, 2021 (see Note 5 for further details) and BR2 facility, which is under construction in Osceola, Arkansas. As of December 31, 2021, the Mini Mill segment includes the operating results of U. S. Steel’s two electric arc furnace steel

Table of Contents

plant in Osceola, Arkansas involved in the production of sheets and electrical products. These operations primarily serve North American customers in the service center, conversion, transportation (including automotive), construction, container and appliance and electrical markets.

The USSE segment includes the operating results of USSK, U. S. Steel’s integrated steel plant and coke production facilities in Slovakia, and its subsidiaries. USSE conducts its business mainly in Central and Western Europe and primarily serves customers in the European transportation (including automotive), construction, container, appliance, electrical, service center, conversion and oil, gas and petrochemical markets. USSE produces and sells slabs, strip mill plate, sheet, tin mill products and spiral welded pipe.

The Tubular segment includes the operating results of U. S. Steel’s tubular production facilities and an equity investee in the United States. These operations produce and sell rounds, seamless and electric resistance welded (welded) steel casing and tubing (commonly known as oil country tubular goods or OCTG), standard and line pipe and mechanical tubing and primarily serve customers in the oil, gas and petrochemical markets. The Tubular segment includes the electric arc furnace at our Fairfield Tubular Operations in Fairfield, Alabama.

The chief operating decision maker evaluates performance and determines resource allocations based on a number of factors, the primary measure being earnings (loss) before interest and income taxes. Earnings (loss) before interest and income taxes for reportable segments and the Other category does not include net interest and other financial costs (income), income taxes, and certain other items that management believes are not indicative of future results.

The accounting principles applied at the operating segment level in determining earnings (loss) before interest and income taxes are generally the same as those applied at the consolidated financial statement level. Intersegment sales and transfers are accounted for at market-based prices and are eliminated at the corporate consolidation level. Corporate-level selling, general and administrative expenses and costs related to certain former businesses are allocated to the reportable segments and Other based on measures of activity that management believes are reasonable.

5. Acquisitions and Dispositions

Big River Steel Acquisition

On January 15, 2021, U. S. Steel purchased the remaining equity interest in Big River Steel for approximately $625 million in cash net of $36 million and $62 million in cash and restricted cash received, respectively, and the assumption of liabilities of approximately $50 million. There were acquisition related costs of approximately $9 million during the twelve months ended December 31, 2021.

Prior to the closing of the acquisition on January 15, 2021, U. S. Steel accounted for its 49.9% equity interest in Big River Steel under the equity method as control and risk of loss were shared among the joint venture members. Using step acquisition accounting the Company increased the value of its previously held equity investment to its fair value of $770 million which resulted in a gain of approximately $111 million. The fair value of the previously held equity investment was determined using Level 3 valuation techniques, including the significant factors and assumptions used to value Big River Steel disclosed below. The gain was recorded in gain on equity investee transactions in the Consolidated Statement of Operations.

The acquisition has been accounted for in accordance with ASC 805, Business combinations. There were step-ups to fair value of approximately $308 million, $194 million and $24 million for property, plant and equipment, debt and inventory, respectively. An intangible asset for customer relationships and goodwill of approximately $413 million and $916 million were also recorded, respectively. Goodwill represents the excess of purchase price over the fair market value of the net assets. Goodwill is primarily attributable to Big River Steel's operational abilities, workforce and the anticipated benefits from their recent expansion and is expected to be tax deductible. The inventory step-up was fully amortized as of March 31, 2021, the intangible asset will be amortized over a 22-year period, and the debt step-up will be amortized over the contractual life of the underlying debt.

The value of Big River Steel was determined using Level 3 valuation techniques. Level 3 valuation techniques include inputs to the valuation methodology that are considered unobservable and significant to the fair value measurement. A significant factor in determining the equity value was the discounted forecasted cash flows of Big River Steel. Forecasted cash flows are primarily impacted by the forecasted market price of steel and metallic inputs as well as the expected timing of significant capital expenditures. The model utilized a risk adjusted discount rate of 11.0% and a terminal growth rate of 2%.

(1) The transaction to purchase Big River Steel included receivables for payments made by Big River Steel on behalf of U. S. Steel for retention bonuses of $22 million that impacted the previously held equity investment and for U. S. Steel liabilities assumed in the purchase of approximately $50 million. In addition, there were assumed receivables of approximately $27 million for steel substrate sales from Big River Steel to U. S. Steel. The receivables with U. S. Steel eliminate in consolidation with offsetting intercompany payables from U. S. Steel.

The following unaudited pro forma information for U. S. Steel includes the results of the Big River Steel acquisition as if it had been consummated on January 1, 2020. The unaudited pro forma information is based on historical information and is adjusted for amortization of the intangible asset, property, plant and equipment and debt fair value step-ups discussed above. Non-recurring acquisition related items included in the 2020 period include $111 million for the gain on previously held equity investment, $9 million in acquisition related costs and $24 million in inventory step-up amortization related to the purchase of the remaining interest in Big River Steel. In addition, costs for non-recurring retention bonuses of $44 million that occurred in January 2021 prior to the purchase of the remaining equity interest are included in the 2020 period. The pro forma information does not include any anticipated cost savings or other effects of the integration of Big River Steel. Accordingly, the unaudited pro forma information does not necessarily reflect the actual results that would have occurred, nor is it necessarily indicative of future results of operations. Pro forma adjustments were not tax-effected in 2020 as U. S. Steel had a full valuation allowance on its domestic deferred tax assets.

Transtar Disposition

On July 28, 2021, U. S. Steel completed the sale of 100 percent of its equity interests in its wholly-owned short-line railroad, Transtar, LLC (Transtar) to an affiliate of Fortress Transportation and Infrastructure Investors, LLC. The Company received net cash proceeds of $627 million, subject to certain customary adjustments as set forth in the Membership Interest Purchase Agreement, and recognized a pretax gain of approximately $506 million in 2021. In connection with the closing of the transaction, the Company entered into certain ancillary agreements including a railway services agreement, providing for continued rail services for its Gary Works and Mon Valley Works facilities, and a transition services agreement. Because Transtar does not represent a significant component of U. S. Steel's business and does not

Table of Contents

constitute a reportable business segment, its results through the date of disposition are reported in the Other category. See Note 4 for further details.

Other Transactions

As of December 31, 2022, the Company intends to pursue the disposition of certain assets related to a component of its flat-roll business. As a result, the Company has recognized a total of $119 million in restructuring-related charges, $89 million during the fourth quarter 2021 and $30 million during the year ended December 31, 2022. These charges are expected to be paid out on a long-term basis.

USS-UPI, LLC (UPI) (formerly known as USS-POSCO Industries)

On February 29, 2020, U. S. Steel purchased the remaining 50% ownership interest in USS-POSCO Industries, (now USS-UPI, LLC), (UPI) for $3 million, net of cash received of $2 million. There was an assumption of accounts payable owed to U. S. Steel for prior sales of steel substrate of $135 million associated with the purchase that was reflected as a reduction in receivables from related parties on the Company's Consolidated Balance Sheet as of December 31, 2020.

Using step acquisition accounting U. S. Steel increased the value of the Company's previously held equity investment to its fair value of $5 million which resulted in a gain of approximately $25 million. The gain was recorded in gain on equity investee transactions in the Consolidated Statement of Operations.

Receivables of $44 million, inventories of $96 million, accounts payable and accrued liabilities of $19 million, current portion of long-term debt of $55 million and payroll and employee benefits liabilities of $78 million were recorded with the acquisition. Property, plant and equipment of $97 million which included a fair value step-up of $47 million and an intangible asset of $54 million were also recorded on the Company's Consolidated Balance Sheet. The intangible asset, which will be amortized over ten years, arises from a land lease contract, under which a certain portion of payment owed to UPI is realized in the form of deductions from electricity costs.

6. Revenue

Revenue is generated primarily from contracts to produce, ship and deliver steel products, and to a lesser extent, raw materials sales such as iron ore pellets and coke by-products and real estate sales. Generally, U. S. Steel’s performance obligations are satisfied and revenue is recognized when title transfers to our customer for product shipped or services are provided. Revenues are recorded net of any sales incentives. Shipping and other transportation costs charged to customers are treated as fulfillment activities and are recorded in both revenue and cost of sales at the time control is transferred to the customer. Costs related to obtaining sales contracts are incidental and are expensed when incurred. Because customers are invoiced at the time title transfers and U. S. Steel’s right to consideration is unconditional at that time, U. S. Steel does not maintain contract asset balances. Additionally, U. S. Steel does not maintain contract liability balances, as performance obligations are satisfied prior to customer payment for product. U. S. Steel offers industry standard payment terms.

The following tables disaggregates our revenue by product for each of our reportable business segments for the years ended December 31, 2022, 2021 and 2020, respectively (Net Sales by Product, in millions, excluding intersegment sales):

8. Earnings (Loss) and Dividends Per Common Share

Earnings (Loss) per Share Attributable to United States Steel Corporation Stockholders

Basic earnings (loss) per common share is based on the weighted average number of common shares outstanding during the period.

Diluted earnings (loss) per common share assumes the exercise of stock options, the vesting of restricted stock units and performance awards, provided in each case the effect is dilutive. In 2022, the "if-converted" method is used to calculate the dilutive effect of the Senior Convertible Notes due in 2026 as a result of ASU 2020-06. In 2021 and 2020, the "treasury stock" method was used to calculate the dilutive effect of the Senior Convertible Notes due in 2026 (due to our intent and policy, among other factors, to settle the principal amount of the 2026 Senior Convertible Notes in cash upon conversion).

In March 2022, the Company and the Arkansas Economic Development Commission entered into the Recycling Tax Credit Incentive Agreement, whereby the Company may earn state income tax credits in an amount equal to 30 percent of the cost of waste reduction, reuse, or recycling equipment, subject to meeting the requirements of the Arkansas Code Ann. Section 26-51-506, for BR2 which is under construction in Osceola, Arkansas. Documentation supporting the Company's investment in qualifying equipment must be submitted as part of an application for certification expected to be completed on or before 2025. In March 2022, the Company received a lump-sum payment of approximately $82 million as proceeds from the sale of a portion of expected future tax credits to be earned by the Company (see Note 26 for additional information). The Company estimates that it could earn tax credits in excess of $700 million, exclusive of the amount sold in March 2022, which the Company will recognize in the year the assets are placed into service and meet the requirements of Arkansas Code Ann. Section 26-51-506. Any unused tax credit that cannot be claimed in a tax year may be carried forward indefinitely by the Company and applied to its future state tax liability.

On August 16, 2022, H.R. 5376 (commonly called the Inflation Reduction Act of 2022) was signed into law, which, among other things, implemented a CAMT of 15 percent on book income of certain large corporations, a one percent excise tax on net stock repurchases and several tax incentives to promote clean energy. The provision pertaining to an excise tax on corporate stock repurchases imposes a nondeductible one percent excise tax on a publicly traded corporation for the net value of certain stock that the corporation repurchases. The value of the repurchases subject to the tax is reduced by the value of any stock issued by the corporation during the tax year, including stock issued or provided to the employees. The CAMT imposes a minimum tax on net income adjusted for certain items prescribed by the legislation. Both the CAMT and the excise tax provisions of this legislation are effective for tax years beginning after December 31, 2022. Although management is currently assessing the impact of the law change and awaiting guidance from the Department of Treasury,

Table of Contents

the Company anticipates being subject to the new CAMT but does not believe that it will have a material impact on its Consolidated Financial Statements.

Included in the 2021 provision is a benefit of $715 million related to the reversal of a portion of the valuation allowance recorded against the Company’s net domestic deferred tax asset, partially offset by the addition of a valuation allowance of $82 million, the majority of which relates to an unused capital loss carryforward.

The 2020 tax benefit includes a $138 million benefit related to recording a loss from continuing operations and income from other comprehensive income categories and expense of $13 million for an updated estimate to tax reserves related to an unrecognized tax benefit. Due to the full valuation allowance on our domestic deferred tax assets, the tax benefit in 2020 does not reflect any additional tax benefit for domestic pretax losses.

U. S. Steel recognizes deferred tax assets and liabilities for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. The realization of deferred tax assets is assessed quarterly based on several interrelated factors. These factors include U. S. Steel’s expectation to generate sufficient future taxable income and the projected time period over which these deferred tax assets will be realized.

Each quarter U. S. Steel analyzes the likelihood that our deferred tax assets will be realized. A valuation allowance is recorded if, based on the weight of all available positive and negative evidence, it is more likely than not that some portion, or all, of a deferred tax asset will not be realized.

At June 30, 2021, U. S. Steel determined, based upon weighing all positive and negative evidence, that a full valuation allowance for the domestic deferred tax assets was no longer required. Accordingly, we reversed all of the domestic valuation allowance except for a portion of the domestic valuation allowance related to certain state net operating losses and state tax credits.

Table of Contents

During the year ended December 31, 2021, U. S. Steel realized a non-cash net benefit of $715 million related to the valuation allowance release, which was partially offset by the addition of a valuation allowance of $82 million, the majority of which relates to an unused capital loss generated in the fourth quarter of 2021.

At December 31, 2022, the net domestic deferred tax liability was $437 million, net of an established valuation allowance of $116 million. At December 31, 2021, the net domestic deferred tax liability was $88 million, net of an established valuation allowance of $159 million.

At December 31, 2022, the net foreign deferred tax liability was $9 million, net of an established valuation allowance of $3 million. At December 31, 2021, the net foreign deferred tax liability was $2 million, net of an established valuation allowance of $3 million. The net foreign deferred tax asset will fluctuate as the value of the U.S. dollar changes with respect to the euro.

U. S. Steel will continue to monitor the realizability of its deferred tax assets on a quarterly basis. In the future, if we determine that realization is more likely than not for a deferred tax asset with a valuation allowance, the related valuation allowance will be reduced, and we will record a non-cash benefit to earnings.

Unrecognized tax benefits

Unrecognized tax benefits are the differences between a tax position taken, or expected to be taken, in a tax return and the benefit recognized for accounting purposes pursuant to the guidance in ASC Topic 740 on income taxes. The total amount of unrecognized tax benefits was $2 million, $3 million and $16 million as of December 31, 2022, 2021 and 2020, respectively.

The total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate was $2 million as of both December 31, 2022 and 2021.

U. S. Steel records interest related to uncertain tax positions as a part of net interest and other financial costs in the Consolidated Statements of Operations. Any penalties are recognized as part of selling, general and administrative expenses. U. S.

U. S. Steel's portion of the income (loss) from investees reflected on the Consolidated Statements of Operations was $243 million, $170 million and $(117) million for the years ended December 31, 2022, 2021 and 2020, respectively.

All of our significant investees are located in the U.S. Investees accounted for using the equity method include:


Investee	December 31, 2022 Interest
Chrome Deposit Corporation	50	%
Daniel Ross Bridge, LLC	50	%
Double G Coatings Company, Inc.	50	%
Hibbing Development Company	24.1	%
Hibbing Taconite Company(a)	14.7	%
Patriot Premium Threading Services, LLC	50	%
PRO-TEC Coating Company, LLC	50	%
Strategic Investment Fund Partners II(b)	5.2	%
Worthington Specialty Processing	49.0	%

(a)Hibbing Taconite Company (Hibbing) is an unincorporated joint venture that is owned, in part, by Hibbing Development Company (HDC), which is accounted for using the equity method. Through HDC we are able to influence the activities of HTC, and as such, its activities are accounted for using the equity method.

(b)Strategic Investment Fund Partners II is a limited partnership and in accordance with ASC Topic 323, the financial activities are accounted for using the equity method.

In 2020, we recognized pre-tax gains on equity investee transactions of approximately $6 million on the sale of our 49 percent ownership interest in Feralloy Processing Company and $25 million for the step-up to fair value of our previously held investment in UPI.

In 2022, we recognized pre-tax gains on equity investee transactions of approximately $6 million from Worthington Specialty Processing pertaining to the sale of the joint venture's facilities and subsequent distribution to the investors. The joint venture is expected to be dissolved in 2023 and is expected to result in an immaterial distribution to the Company.

Dividends or partnership distributions received from equity investees were $28 million in 2022 and $2 million in 2021, respectively. There were none received in 2020.

U. S. Steel evaluates impairment of its equity method investments whenever circumstances indicate that a decline in value below carrying value is other than temporary. Under these circumstances, we would adjust the investment down to its estimated fair value, which then becomes its new carrying value.

We supply substrate to certain of our equity method investees and from time to time will extend the payment terms for their trade receivables. For discussion of transactions and related receivable and payable balances between U. S. Steel and its investees, see Note 23.

15. Stock-Based Compensation Plans

U. S. Steel has outstanding stock-based compensation awards that were granted by the Compensation & Organization Committee of the Board of Directors (the Committee), or its designee, under the 2005 Stock Incentive Plan (the 2005 Plan) and the 2016 Omnibus Incentive Compensation Plan, as amended and restated (the Omnibus Plan) (collectively the Plans). On April 26, 2016, the Company's stockholders approved the Omnibus Plan and authorized the Company to issue up to 7,200,000 shares of U. S. Steel common stock under the Omnibus Plan. The Company's stockholders authorized the issuance of an additional 6,300,000 shares under the Omnibus Plan on April 25, 2017, an additional 4,700,000 shares under the Omnibus Plan on April 28, 2020 and an additional 14,500,000 shares under the Omnibus Plan on April 27, 2021. While awards that were previously granted under the 2005 Plan remain outstanding, all future awards will be granted under the Omnibus Plan. As of December 31, 2022, there were 9,080,478 shares available for future grants under the Omnibus Plan.

Table of Contents

Generally, a share issued under the Omnibus Plan pursuant to an award other than a stock option will reduce the number of shares available under the Stock Plan by 1.78 shares. Shares related to awards under either plan (i) that are forfeited, (ii) that terminate without shares having been issued or (iii) for which payment is made in cash or property other than shares, are again available for awards under the Omnibus Plan. Shares delivered to U. S. Steel or withheld for purposes of satisfying the exercise price or tax withholding obligations are not available for future awards. The purpose of the Plans is to attract, reward and retain employees and non-employee directors who create long-term value for our stockholders by delivering on objectives that support our long-term strategy. The Committee administers the Plans, and under the Omnibus Plan may make grants of stock options, restricted stock units (RSUs), performance awards, and other stock-based awards.

The following table summarizes the total stock-based compensation awards granted during the years 2022, 2021 and 2020:


	Stock Options	Restricted Stock Units	TSR Performance Awards	ROCE Performance Awards (a)	Performance-Based Restricted Stock Units
2022	—	1,249,830	236,520	408,870	83,951
2021	171,000	1,891,481	306,930	485,900	676,954
2020	—	2,640,690	671,390	—	—

(a) The ROCE awards granted in 2020 are not shown in the table because they were granted in cash.

Stock-based compensation expense

The following table summarizes the total compensation expense recognized for stock-based compensation awards:


(In millions, except per share amounts)	Year Ended December 31, 2022		Year Ended December 31, 2021		Year Ended December 31, 2020
Stock-based compensation expense recognized:
Cost of sales	$	15	$	14	$	8

Decrease in basic earnings per share	0.18		0.16		0.13
Decrease in diluted earnings per share	0.16		0.15		0.13

(a) Amounts for 2020 do not reflect a tax benefit as a result of a full valuation allowance on our domestic deferred tax assets.

As of December 31, 2022, total future compensation cost related to nonvested stock-based compensation arrangements was $45 million and the average period over which this cost is expected to be recognized is approximately 16 months.

Stock options

Compensation expense for stock options is recorded over the vesting period based on the fair value on the date of grant, as calculated by U. S. Steel using the Black-Scholes model and the assumptions listed below. Awards generally vest ratably over a three-year service period and have a term of ten years. Stock options are generally issued at the average market price of the underlying stock on the date of the grant. Upon exercise of stock options, shares of U. S. Steel stock are issued from treasury stock or from authorized, but unissued common stock. There were 171,000 performance-based stock options granted in 2021. There were no stock options granted in 2022 and 2020.

The expected annual dividends per share are based on the latest annualized dividend rate at the date of grant; the expected life in years is determined primarily from historical stock option exercise data; the expected volatility is based on the historical volatility of U. S. Steel stock; and the risk-free interest rate is based on the U.S. Treasury strip rate for the expected life of the option.

The 171,000 performance-based stock options granted in December 2021 do not become vested and exercisable until the Company's 20-trading day average closing stock price meets or exceeds the following stock price hurdles during the seven-year period beginning on the grant date, as follows:


20-trading day Average Closing Stock Price Achievement During 7-Year Period Beginning on Grant Date (a)		Percentage of Performance-Based Stock Options Exercisable
$	35.00	33.33	%
$	45.00	33.33	%
$	55.00	33.34	%

Table of Contents

(a) The $35.00 tranche vested in April 2022.

The following table shows a summary of the status and activity of stock options for the year ended December 31, 2022:


	Shares	Weighted- Average Exercise Price (per share)		Weighted- Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value (in millions)
Outstanding at January 1, 2022	1,659,764	$	25.31
Granted	—	$	—
Exercised	(408,760)	$	20.29
Forfeited or expired	(40,789)	$	29.08
Outstanding at December 31, 2022	1,210,215	$	26.88	2.97	$	3
Exercisable at December 31, 2022	1,096,215	$	27.24	2.65	$	2
Exercisable and expected to vest at December 31, 2022	1,210,215	$	26.88	2.97	$	3

The aggregate intrinsic value in the table above represents the total pretax intrinsic value (difference between our closing stock price on the last trading day of 2022 and the exercise price, multiplied by the number of in-the-money options). Intrinsic value changes are a function of the fair market value of our stock.

The total intrinsic value of stock options exercised (i.e., the difference between the market price at exercise and the price paid by the employee to exercise the option) was $5 million and $3 million during the years ended December 31, 2022 and December 31, 2021, respectively, and immaterial during the year ended December 31, 2020. The total amount of cash received by U. S. Steel from the exercise of options was $8 million and $7 million during the years ended December 31, 2022 and December 31, 2021, respectively. The related net tax benefit realized from the exercise of these options was immaterial in 2022 and 2021.

Stock awards

Compensation expense for nonvested stock awards is recorded over the vesting period based on the fair value at the date of grant.

RSUs awarded as part of annual grants generally vest ratably over three years. Their fair value is the average market price of the underlying common stock on the date of grant. RSUs granted in connection with new-hire or retention awards generally cliff vest three years from the date of the grant.

Total shareholder return (TSR) performance awards may vest at varying levels at the end of a three-year performance period if U. S. Steel’s total shareholder return compared to the total shareholder return of a peer group of companies meets performance criteria during the three-year performance period. TSR is calculated as follows: 20 percent for each year in the three-year performance period and 40 percent for the full three-year period. TSR performance awards may vest and payout 50 percent at the threshold level, 100 percent at the target level and 200 percent at the maximum level for payouts. Payment for performance in between the threshold percentages will be interpolated. The fair value of the performance awards is calculated using a Monte-Carlo simulation.

Performance awards based on the return on capital employed (ROCE) metric were granted in equity in 2022 and 2021, and in cash in 2020. ROCE awards granted will be measured on a weighted average basis of the Company’s consolidated worldwide earnings (loss) before interest and income taxes, as adjusted, divided by consolidated worldwide capital employed, as adjusted, over a three year period.

For outstanding 2020 and 2021 ROCE-based equity awards, weighted average ROCE is calculated based on the ROCE achieved in the first, second and third years of the performance period, weighted at 20 percent, 30 percent and 50 percent, respectively. For outstanding 2022 ROCE-based equity awards, weighted average ROCE is calculated based on the ROCE achieved in the first, second and third years of the performance period, weighted at 20 percent for each year in the three-year performance period and 40 percent for the full three-year period. The ROCE awards will payout 50 percent at the threshold level, 100 percent at the target level and 200 percent at the maximum level. Payouts for performance in between the threshold percentages will be interpolated.

Compensation expense associated with the ROCE awards will be contingent based upon the achievement of the specified ROCE performance goals and will be adjusted on a quarterly basis to reflect the probability of achieving the ROCE metric.

ROCE performance awards may vest at the end of a three-year performance period contingent upon meeting ROCE performance goals approved by the Committee. The fair value of the ROCE performance awards is the average market price of the underlying common stock on the date of grant.

Table of Contents

In December 2021 and August 2022, special performance-based restricted stock unit awards (PSUs) were granted to members of the Company’s executive leadership team. Shares are earned based on the achievement of certain pre-set quantitative performance criteria during the four-year performance period, January 1, 2022 through December 31, 2025. Shares may vest following the expiration of the Performance Period if the Company satisfies the performance criteria.

The Chief Executive Officer was granted PSUs that vest with the following, equally weighted, performance metrics: (i) EBITDA margin expansion, (ii) greenhouse gas emissions intensity reduction, (iii) asset portfolio optimization, (iv) leverage metrics and (v) corporate relative valuation. Other members of the executive leadership team were granted PSUs that vest with performance criteria related to: (i) on time and on budget completion of the second mini mill (30% of the grant), (ii) EBITDA margin expansion (40% of the grant) and (iii) greenhouse gas emissions intensity reduction (30% of the grant).

For the PSU awards, a payout is achievable at threshold (50% of target), target (100% of target) or maximum (200% of target) performance achievement. Payout amounts will be interpolated between the threshold, target and maximum amounts.

The following table shows a summary of the performance awards outstanding as of December 31, 2022, and their fair market value on the respective grant date:

During the years ended December 31, 2022, 2021, and 2020, the total fair value of shares vested was $45 million, $29 million, and $16 million, respectively.

16. Derivative Instruments

U. S. Steel is exposed to foreign currency exchange rate risks in our European operations. USSE’s revenues are primarily in euros and costs are primarily in euros and U.S. dollars. U. S. Steel uses foreign exchange forward sales contracts (foreign exchange forwards) with maturities up to 23 months to manage our currency requirements and exposure to foreign currency exchange rate fluctuations. Derivative instruments are required to be recognized at fair value in the Consolidated Balance Sheet. The USSE and Flat-Rolled segments use hedge accounting for their foreign exchange forwards. The Mini Mill segment has foreign exchange forwards for which hedge accounting has not been elected; therefore, the changes in the fair value of their foreign exchange forwards are recognized immediately in the Consolidated Statements of Operations (mark-to-market accounting).

Table of Contents

U. S. Steel also uses financial swaps to protect from the commodity price risk associated with purchases of natural gas, zinc, tin, electricity, and iron ore pellets (commodity purchase swaps). We elected cash flow hedge accounting for commodity purchase swaps for natural gas, zinc, tin, and iron ore pellets and use mark-to-market accounting for electricity swaps. The commodity purchase swaps where hedge accounting was elected have maturities up to 12 months. The commodity purchase swaps where hedge accounting was not elected have maturities up to 12 months.

U. S. Steel has entered into financial derivatives that are used to partially manage the sales price risk of certain hot-rolled coil sales (sales swaps) and iron ore pellet sales (sales swaps and zero cost collars). The sales swaps and the zero cost collars are all accounted for using hedge accounting. The hot-rolled coil sales swaps and the iron ore zero cost collars have reached maturity, and the iron ore sales swaps have maturities up to 13 months.

Generally, forward physical purchase contracts qualify for the normal purchase and normal sales exceptions described in ASC Topic 815 and are not subject to mark-to-market accounting. In accordance with the guidance in ASC Topic 820 on fair value measurements and disclosures, the fair value of our foreign exchange forwards, commodity purchase swaps and sales swaps was determined using Level 2 inputs, which are defined as "significant other observable" inputs. The inputs used are from market sources that aggregate data based upon market transactions.

The table below shows the outstanding swap quantities used to hedge forecasted purchases and sales as of December 31, 2022, and December 31, 2021:


Hedge Contracts	Classification	December 31, 2022	December 31, 2021
Natural gas (in mmbtus)	Commodity purchase swaps	45,174,000	40,498,000

2026 Senior Convertible Notes

In October 2019, U. S. Steel issued $350 million of 5.00% Senior Convertible Notes due November 1, 2026 (2026 Senior Convertible Notes). Interest on the 2026 Senior Convertible Notes is payable semi-annually on May 1 and November 1 of each year. The initial conversion rate for the 2026 Senior Convertible Notes is 74.8391 shares of U. S. Steel common stock per $1,000 principal amount, equivalent to an initial conversion price of approximately $13.36 per share of common stock, subject to adjustment pursuant to the 2026 Senior Convertible Notes indenture. Based on the initial conversion rate, the 2026 Senior Convertible Notes are convertible into 26,193,685 shares of U. S. Steel common stock and we reserved for the possible issuance of 33,396,930 shares, which is the maximum amount that could be issued upon conversion. Prior to August 1, 2026, holders of notes may convert all or a portion of their notes at their option only upon the satisfaction of specified conditions and during certain periods. On or after August 1, 2026, holders may convert all or a portion of their notes prior to the maturity date. Upon conversion, we will satisfy the obligation with cash, common stock, or a combination thereof, at our election. U. S. Steel may not redeem the 2026 Senior Convertible Notes prior to November 5, 2023. On or after November 5, 2023, and prior to August 1, 2026, if the price per share of U. S. Steel's common stock has been at least 130% of the conversion price for specified periods, U. S. Steel may redeem all or a portion of the 2026 Senior Convertible Notes at a cash redemption price of 100% of the principal amount, plus accrued and unpaid interest.

Table of Contents

If U. S. Steel undergoes a fundamental change, as defined in the 2026 Senior Convertible Notes, holders may require us to repurchase the 2026 Senior Convertible Notes in whole or in part for cash at a price equal to 100% of the principal amount of the 2026 Senior Convertible Notes to be purchased plus any accrued and unpaid interest up to, but excluding the repurchase date.

Big River Steel — Sustainability Linked ABL Facility

Big River Steel's amended senior secured asset-based revolving credit facility (Big River Steel ABL Facility) matures on July 23, 2026. The facility is secured by first-priority liens on accounts receivable and inventory and certain other assets and second priority liens on most tangible and intangible assets of Big River Steel in each case subject to permitted liens. Additionally, the amendment includes sustainability targets related to greenhouse gas emissions intensity reduction, safety performance and facility certification by ResponsibleSteel™.

The Big River Steel ABL Facility provides for borrowings for working capital and general corporate purposes in an amount equal up to the lesser of (a) $350 million and (b) a borrowing base calculated based on specified percentages of eligible accounts receivables and inventory, subject to certain adjustments and reserves.

Big River Steel LLC must maintain a fixed charge coverage ratio of at least 1.00 to 1.00 for the most recent twelve consecutive months when availability under the Big River Steel ABL Facility is less than the greater of ten percent of the borrowing base availability and $13 million. Based on the most recent four quarters as of December 31, 2022, Big River Steel would have met the fixed charge coverage ratio test. The facility includes affirmative and negative covenants and events of default that are customary for facilities of this type.

There were no loans outstanding under the Big River Steel ABL Facility at December 31, 2022.

U. S. Steel — Sustainability Linked Credit Facility Agreement

On May 27, 2022, U. S. Steel entered into the Sixth Amended and Restated Credit Facility Agreement (Credit Facility Agreement) to replace the existing Fifth Amended and Restated Credit Facility Agreement (Fifth Credit Facility Agreement). The Credit Facility Agreement has substantially the same terms as the Fifth Credit Facility Agreement, except the Credit Facility Agreement references the Secured Overnight Financing Rate instead of the London Interbank Offered Rate, adjusts the individual lenders' commitments, and renews the five-year maturity to May 27, 2027. The Credit Facility Agreement also adjusts the threshold for the fixed charge coverage ratio. The total availability under the facility remained the same at $1,750 million, and the financial impact from replacing the Fifth Credit Facility Agreement was immaterial. Consistent with the Fifth Credit Facility Agreement, the Credit Facility Agreement is secured by first-priority liens on certain accounts receivable and inventory and includes targets related to greenhouse gas emissions intensity reduction, safety performance and facility certification by ResponsibleSteel™.

The Credit Facility Agreement provides for borrowings for working capital and general corporate purchases in an amount equal to the lesser of (a) $1,750 million or (b) a borrowing base calculated based on specified percentages of eligible accounts receivable and inventory, subject to certain adjustments and reserves. As of December 31, 2022, there were approximately $4 million of letters of credit issued and no loans drawn under the Credit Facility Agreement. U. S. Steel must maintain a fixed charge coverage ratio of at least 1.00 to 1.00 for the most recent four consecutive quarters when availability under the Credit Facility Agreement is less than the greater of ten percent of the maximum facility availability and $140 million. Based on the most recent four quarters as of December 31, 2022, the Company would have met the fixed charge coverage ratio test.

USSK Credit Facilities

On September 29, 2021, USSK entered into a €300 million (approximately $320 million) unsecured sustainability linked credit agreement (USSK Credit Agreement). The USSK Credit Agreement matures in 2026 and contains specific financial covenants as well as sustainability targets related to greenhouse gas emissions intensity reduction, safety performance and facility certification by ResponsibleSteel™. At December 31, 2022, USSK had no borrowings under the USSK Credit Agreement.

Under the USSK Credit Agreement, USSK is required to maintain a net debt to EBITDA ratio of less than 3.50:1.00 for the rolling twelve months ending June 30, 2023. The Company has determined that it may not be able to comply with the EBITDA ratio covenant at June 30, 2023, based on the currently forecasted EBITDA for the twelve-month period ending June 30, 2023. This could partially or fully limit USSK’s ability to borrow under the USSK Credit Agreement.

Any amendment or waiver may lead to additional lender protections, including a reduction of loan commitments or less favorable terms, and there can be no assurance that USSK can obtain waivers or amendments in timely fashion, or on acceptable terms or at all. The Company believes that USSK will have adequate cash on hand as of June 30, 2023, and will not need to borrow under the USSK Credit Agreement.

At December 31, 2022, USSK had no borrowings under its €20 million credit facility (approximately $21 million) (USSK Credit Facility) and the availability was approximately $5 million due to approximately $16 million of customs and other guarantees outstanding.

18. Pensions and Other Benefits

U. S. Steel has defined contribution or multiemployer retirement benefits for more than 80 percent of its employees in the United States and non-contributory defined benefit pension plans covering the remaining employees. Benefits under the defined benefit pension plans are based upon years of service and final average pensionable earnings, with a minimum benefit based upon years of service. In addition, pension benefits for most non-represented employees under these plans are based upon a percent of total career pensionable earnings. Effective December 31, 2015, non-represented participants in the defined benefit plan no longer accrue additional benefits under the plan. For those non-represented employees without defined benefit coverage (defined benefit pension plan was closed to new participants in 2003) and those for which the defined benefit plan was frozen, the Company also provides in the defined contribution plans (401(k) plans) a retirement account benefit based on salary and attained age. Most non-represented employees also participate in the 401(k) plans whereby the Company matches a certain percentage of salary based on the amount contributed by the participant. As of December 31, 2022, more than 75 percent of U. S. Steel’s represented employees in the United States are covered by the SPT, a multiemployer pension plan, to which U. S. Steel contributes on the basis of a fixed dollar amount for each hour worked.

Certain hourly employees of U. S. Steel’s flat-rolled, tubular, cokemaking and iron ore operations in the United States are covered by collective bargaining agreements with the USW entered into effective September 1, 2022 (the 2022 Labor Agreements) that expire on September 1, 2026. The 2022 Labor Agreements include a signing bonus for each eligible USW-represented employee and annual 5% wage increases effective September 1, 2022, 2023, 2024 and 2025. Additionally, the 2022 Labor Agreements provide for increases to our pension and retirement benefits, including increases to our defined benefit pension plan, retiree healthcare contributions, and to the contribution rate to the SPT from $3.50 to $4.00 per hour effective January 1, 2023. During the fourth quarter of 2022, U. S. Steel recorded a charge of approximately $67 million for the 2022 Labor Agreements signing bonus and related costs which was recognized primarily as a component of Cost of sales on the Consolidated Statements of Operations.

In addition, as part of the collective bargaining process, U. S. Steel and the USW agreed to leverage the overfunded OPEB plans to support the benefits provided to active represented employees. Beginning January 1, 2023, this agreement allows the Company to use a certain amount of surplus VEBA assets (the surplus amount) to pay for legally permissible benefits under Section 501(c)(9) of the Internal Revenue Code for active employees and retirees of the USW. The surplus amount will represent a one-time transfer of VEBA assets to a subaccount to be used for these employees and retirees, which will take place in the first quarter 2023. The surplus amount of $595 million was determined as of December 31, 2022 (after merger of the UPI VEBA) and is the balance of VEBA assets in excess of 135% of the retiree obligation. The Company will be permitted to withdraw a target of $75 million annually, with a guaranteed annual minimum of $50 million, on a quarterly pro rata basis, from the subaccount to cover the cost of the permissible benefits for active USW employees and USW retirees. As a result of its designation for this purpose, the surplus amount is presented as $75 million in Other current assets and $520 million in Other noncurrent assets on the Consolidated Balance Sheet as of December 31, 2022. Pursuant to the agreement with the USW, the Company merged the United States Steel Corporation Plan for Active Employee Insurance Benefits with and into the United States Steel Corporation Plan for Retiree Insurance Benefits effective January 1, 2023. Upon the one-time transfer from the VEBA to the subaccount, the surplus assets will no longer be accounted for under ASC 715, Compensation-Retirement Benefits and is instead expected to be accounted for primarily under the provisions of ASC 825 Financial Instruments, which is likely to result in the portfolio being accounted for on a fair value basis, with gains and losses recognized in earnings, and reported as activity in Other financial costs (benefits) on the Company's Consolidated Statements of Operations.

On November 8, 2021, U. S. Steel entered into a commitment agreement with Banner Life Insurance Company and William Penn Life Insurance Company of New York (the “Insurers”) and State Street Global Advisors Trust Company, as independent fiduciary to the United States Steel Corporation Plan for Employee Pension Benefits (Revision of 2003), for the plan to purchase group annuity contracts and transfer approximately $284 million of its pension plan obligations to the Insurers. The purchase of the group annuity contracts was funded directly by the assets of the pension plan. The purchase resulted in the transfer of administrative and benefit-paying responsibilities for approximately 17,800 U.S. retirees and beneficiaries to the Insurers. The Insurers began paying benefits for certain retirees and beneficiaries in the Plan on January 1, 2022. There was no change to the pension benefits for any retirees and beneficiaries as a result of the transaction. As a result of the transaction, the Corporation recognized a non-cash pension settlement charge of approximately $93 million. This amount was reclassified to earnings through Net interest and other financial costs from Accumulated other comprehensive loss.

In addition during 2021, the Company recorded termination charges of approximately $34 million in pensions and $17 million in other benefits related to the planned disposition of a component within the flat-roll segment. These charges were recognized as Restructuring and other charges on the Consolidated Statements of Operations.

In February of 2020, U. S. Steel acquired the remaining 50% ownership of its joint venture with UPI and its associated benefit plans. Upon acquisition, UPI's defined benefit pension and other benefit liability was estimated on a net basis at $8 million and $55 million, respectively.

On October 26, 2022, U. S. Steel entered into an agreement with Pacific Life Insurance Company (the Insurer) and State Street Global Advisors Trust Company, as independent fiduciary to the UPI Pension Plan, for the plan to purchase group annuity contracts and transfer approximately $115 million of its pension plan obligations to the Insurer. The purchase of the group annuity contracts was completed on November 1, 2022 and funded directly by the assets of the pension plan. The purchase resulted in the transfer of the administrative and benefit-paying responsibilities for approximately 850 U.S. retirees and beneficiaries to the Insurer. The Insurer began paying benefits for certain retirees and beneficiaries in the Plan on January 1, 2023. There was no change to the pension benefits for any retirees and beneficiaries as a result of the transaction. As a result of the transaction, the Corporation recognized a non-cash pension settlement credit of approximately $3 million. This amount was reclassified to earnings through Net interest and other financial costs from accumulated other comprehensive loss.

Effective as of December 15, 2022, the UPI Pension Plan was merged into the U. S. Steel pension plan.

U. S. Steel’s defined benefit retiree health care and life insurance plans (Other Benefits) cover the majority of its represented employees in the United States upon their retirement. Health care benefits are provided for Medicare and pre-Medicare retirees, with Medicare retirees largely enrolled in Medicare Advantage Plans. Both are subject to various cost sharing features, and in most cases domestically, an employer cap on total costs. The Other Benefits plan was closed to represented employees hired or rehired under certain conditions on or after January 1, 2016.

The retiree medical and retiree life insurance plans, for non-represented employees were amended to eliminate retiree medical benefits effective December 31, 2017, and to eliminate retiree life insurance benefits for employees who retired after December 31, 2017.

The majority of U. S. Steel’s European employees are covered by government-sponsored programs into which U. S. Steel makes required contributions. Also, U. S. Steel sponsors defined benefit plans for most European employees covering benefit payments due to employees upon their retirement, some of which are government mandated. These same employees receive service awards throughout their careers based on stipulated service and, in some cases, age and service.

The discount rate reflects the current rate at which the pension and Other Benefit liabilities could be effectively settled at the measurement date. In 2017, we refined our discount rate determination process for our U.S. plans by using a bond matching approach to select specific bonds that would satisfy our projected benefit payments. We believe the bond matching approach more closely reflects the process we would employ to settle our pension and other benefits obligations. For our European pension plan, the discount rate is determined using data published by European Central Bank and underlying data provided by EuroMTS Ltd. The discount rate assumptions are updated annually.

Plan Assets

ASC Topic 820 establishes a single definition of fair value, creates a three-tier hierarchy as a framework for measuring fair value based on inputs used to value the Plan's investments, and requires additional disclosure about fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1) and the lowest priority to unobservable inputs (level 3). The three levels of the fair value hierarchy are summarized below:

•Level 1 – Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Plan has the ability to access.

•Level 2 – Inputs to the valuation methodology include:

◦Quoted prices for similar assets or liabilities in active markets;

◦Quoted prices for identical or similar assets or liabilities in inactive markets;

◦Inputs other than quoted prices that are observable for the asset or liability;

◦Inputs that are derived principally from or corroborated by observable market data by correlation or other means

If the asset or liability has a specified (contractual) term, the level 2 input must be observable for substantially the full term of the asset or liability.

•Level 3 – Inputs to the valuation methodology are unobservable and significant to the fair value measurement.

An instrument’s level is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques maximize the use of relevant observable inputs and minimize the use of unobservable inputs. The following is a description of the valuation methodologies used for assets measured at fair value. There have been no changes in the methodologies used at December 31, 2022 and 2021.

Short-term investments are valued at amortized cost which approximates fair value due to the short-term maturity of the instruments. Equity securities - U.S. & International are valued at the closing price reported on the active exchange on which the individual securities are traded. U.S. and Non U.S. government bonds are valued using pricing models maximizing the use of observable inputs for similar securities. Corporate U.S. & Non U.S. bonds are also valued using pricing models maximizing the use of observable inputs for similar securities, which includes basing value on yields currently available on comparable securities of issuers with similar credit ratings. When quoted prices are not available for identical or similar bonds, the bond is valued under a discounted cash flow approach that maximizes observable inputs, such as current yields of similar instruments, but includes adjustments for certain risks that may not be observable, such as credit and liquidity risks. Mortgage and asset-backed securities are valued using quotes from a broker dealer. Private equities and real estate are valued using information provided by external managers for each individual investment held in the fund or using NAV (net asset value) as a practical expedient. Timberland investments are valued at their appraised value. Mineral Interests and other alternatives are valued at the present value of estimated future cash flows discounted at estimated market rates for assets of similar quality and duration.

U. S. Steel’s investment strategy for its U.S. pension and Other Benefits plan assets provides for a diversified mix of high quality bonds, public equities and selected smaller investments in private equities, private credit, timber and mineral interests. For its U.S. pension, U. S. Steel has a target allocation for plan assets of 50 percent in corporate bonds, government bonds and mortgage, private credit, and asset-backed securities. The balance is invested in equity securities, timber, private equity and real estate partnerships. U. S. Steel believes that returns on equities over the long term will be higher than returns from fixed-income securities as actual historical returns from U. S. Steel’s trusts have shown. Returns on bonds tend to offset some of the short-term volatility of stocks. Both equity and fixed-income investments are made across a broad range of industries and companies (both domestic and foreign) to provide protection against the impact of volatility in any single industry as well as company specific developments. U. S. Steel will use a 6.90 percent assumed rate of return on assets for the development of net periodic cost for the main defined benefit pension plan in 2023. Actual

101

Table of Contents

returns since the inception of the plan have exceeded this 6.90 percent rate and while recent annual returns have been volatile, it is U. S. Steel’s expectation that rates will achieve this level in future periods.

Steelworkers Pension Trust

For most bargaining unit employees participating in the SPT, U. S. Steel contributed to the SPT a fixed dollar amount for each hour worked of $3.50 through December 31, 2022. SPT contributions per hour worked increased to $4.00 effective January 1, 2023. U. S. Steel’s contributions to the SPT represented greater than 30% of the total combined contributions of all employers participating in the plan for the years ended December 31, 2022, 2021 and 2020.

Participation in a multi-employer pension plan agreed to under the terms of a collective bargaining agreement differ from a traditional qualified single employer defined benefit pension plan. The SPT shares risks associated with the plan in the following respects:

a. Contributions to the SPT by U. S. Steel may be used to provide benefits to employees of other participating employers;

b. If a participating employer stops contributing to the SPT, the unfunded obligations of the plan may be borne by the remaining participating employers;

c. If U. S. Steel chooses to stop participating in the SPT, U. S. Steel may be required to pay an amount based on the underfunded status of the plan, referred to as a withdrawal liability.

On March 21, 2011 the Board of Trustees of the SPT elected funding relief which has the effect of decreasing the amount of required minimum contributions in near-term years, but will increase the minimum funding requirements during later plan years. As a result of the election of funding relief, the SPT’s zone funding under the Pension Protection Act may be impacted.

In addition to the funding relief election, the Board of Trustees also elected a special amortization rule, which allows the SPT to separately amortize investment losses incurred during the SPT’s December 31, 2008 plan year-end over a 29 year period, whereas they were previously required to be amortized over a 15 year period.

U. S. Steel’s participation in the SPT for the annual periods ended December 31, 2022, 2021 and 2020 is outlined in the table below.


	Employer Identification Number/ Pension Plan Number	Pension Protection Act Zone Status as of December 31 (a)		FIP/RP Status Pending/Implemented(b)	U.S. Steel Contributions (in millions)						Surcharge Imposed(c)		Expiration Date of Collective Bargaining Agreement
Pension Fund		2022	2021		2022		2021		2020		2022	2021
Steelworkers Pension Trust	23-6648508/499	Green	Green	No	$	74	$	75	$	76	No	No	September 1, 2022

(a)The zone status is based on information that U. S. Steel received from the plan and is certified by the plan’s actuary. Among other factors, plans in the green zone are at least 80 percent funded, while plans in the yellow zone are less than 80 percent funded and plans in the red zone are less than 65 percent funded.

(b)Indicates if a financial improvement plan (FIP) or a rehabilitation plan (RP) is either pending or has been implemented.

(c)Indicates whether there were charges to U. S. Steel from the plan.

Cash Flows

The following information is in addition to the contributions to the SPT noted in the table above.

Employer Contributions – U. S. Steel did not make any voluntary or mandatory contributions to the U. S. Steel Retirement Plan Trust in 2022 or 2021. The U. S. Steel Retirement Plan Trust is the funding vehicle for the Company's main defined benefit pension plan.

For pension plans not funded by trusts, U. S. Steel made $2 million, $11 million and $7 million of pension payments not funded by trusts in 2022, 2021 and 2020, respectively.

102

Table of Contents

Cash payments totaling $32 million, $46 million and $46 million were made for other post-employment benefit payments not funded by trusts in 2022, 2021 and 2020, respectively. In 2022, 2021 and 2020, U. S. Steel continued to use assets from our VEBA trust for represented retiree health care and life insurance benefits to pay USW post-employment benefit claims.

Estimated Future Benefit Payments – The following benefit payments, which reflect expected future service as appropriate, are expected to be paid from U. S. Steel’s defined benefit plans:


(In millions)	Pension Benefits		Other Benefits
2023	$	427	$	118
2024	408		114
2025	364		109
2026	357		121
2027	352		122
Years 2028 - 2030	1,619		543

Defined contribution plans

U. S. Steel also contributes to several defined contribution plans for its salaried employees. Effective January 1, 2016, all non-represented salaried employees in North America receive pension benefits in the form of a separate retirement account through a defined contribution plan with contribution percentages based upon age, for which company contributions totaled $21 million, $20 million and $10 million in 2022, 2021 and 2020, respectively. U. S. Steel’s matching contributions to salaried employees’ defined contribution plans, which are 100 percent of the employees’ contributions up to six percent of their eligible salary, totaled $19 million, $18 million and $8 million in 2022, 2021 and 2020, respectively. U. S. Steel also maintains non-qualified defined contribution plans to provide benefits which are otherwise limited by the Internal Revenue Code for qualified plans. U. S. Steel’s contributions under these defined contribution plans were less than $1 million in 2022 and totaled $1 million for both 2021 and 2020.

Most represented employees are eligible to participate in a defined contribution plan where there is no company match on savings except for certain Tubular hourly employees. Effective with the 2015 Labor Agreement, represented hires on or after January 1, 2016 are eligible for a $0.50 per hour savings account contribution. As a result of the 2018 Labor Agreements, the savings account contribution for each hour worked increased to $0.55 effective January 1, 2019, $0.60 effective January 1, 2020, and $0.65 effective January 1, 2021. As a result of the 2022 Labor Agreements, it will be increased to $0.75 effective January 1, 2023. These Company contributions for represented employees totaled $5 million, $4 million and $4 million in 2022, 2021 and 2020, respectively.

Other post-employment benefits

The Company provides benefits to former or inactive employees after employment but before retirement. Certain benefits including workers’ compensation and black lung benefits represent material obligations to the Company and under the guidance for nonretirement post-employment benefits, have historically been treated as accrued benefit obligations. Liabilities for these benefits recorded at December 31, 2022, totaled $88 million as compared to $110 million at December 31, 2021. Liability amounts were developed assuming a discount rate of 5.65% and 2.87% at December 31, 2022 and 2021. Net periodic benefit cost for these benefits is projected to be $16 million in 2023 compared to $(1) million in 2022 and $17 million in 2021.

Pension Funding

In March 2021, the American Rescue Plan Act (ARPA - H.R. 1319) further extended the pension relief interest rate corridor used to measure defined benefit pension obligations for calculating minimum annual contributions. The new interest rate formula results in higher interest rates for minimum funding calculations as compared to prior law over the next few years, which will improve the funded status of our main defined benefit pension plan and reduce minimum required contributions.

U. S. Steel will monitor the funded status of the plan to determine when voluntary contributions may be prudent in order to mitigate potentially larger mandatory contributions in later years.

19. Asset Retirement Obligations

U. S. Steel’s asset retirement obligations (AROs) primarily relate to mine, landfill closure and post-closure costs. The following table reflects changes in the carrying values of AROs for the years ended December 31, 2022 and 2021:


	December 31,
(In millions)	2022		2021
Balance at beginning of year	$	66	$	60

Change in estimate of obligations	(5)		(1)
Foreign currency translation effects	—		(1)
Accretion expense	4		12

Certain AROs related to disposal costs of the majority of fixed assets at our integrated steel facilities have not been recorded because they have an indeterminate settlement date. These AROs will be initially recognized in the period in which sufficient information exists to estimate their fair value.

20. Fair Value of Financial Instruments

The carrying value of cash and cash equivalents, current accounts and notes receivable, accounts payable and accrued interest included in the Consolidated Balance Sheet approximate fair value. See Note 16 for disclosure of U. S. Steel’s derivative instruments, which are accounted for at fair value on a recurring basis.

Stelco Option for Minntac Mine Interest

On April 30, 2020, the Company entered into an Option Agreement with Stelco, that grants Stelco the option to purchase a 25 percent interest (the Option Interest) in a to-be-formed entity (the Joint Venture) that will own the Company’s current iron ore mine located in Mt. Iron, Minnesota (the Minntac Mine). As consideration for the option, Stelco paid the Company an aggregate amount of $100 million in five $20 million installments during the year-ended December 31, 2020 which are recorded net of transaction costs in the Consolidated Balance Sheet. In the event Stelco exercises the option, Stelco will contribute an additional $500 million to the Joint Venture, which amount shall be remitted solely to U. S. Steel in the form of a one-time special distribution, and the parties will engage in good faith negotiations to finalize the master agreement (pursuant to which Stelco will acquire the Option Interest) and the limited liability company agreement of the Joint Venture.

The following table summarizes U. S. Steel’s financial assets and liabilities that were not carried at fair value at December 31, 2022 and 2021.

Related party sales and service transactions are primarily related to equity investees and were $1,942 million, $1,311 million and $976 million in 2022, 2021 and 2020, respectively.

Accounts payable to related parties include balances due to PRO-TEC Coating Company (PRO-TEC) of $142 million and $98 million at December 31, 2022 and 2021, respectively for invoicing and receivables collection services provided by U. S. Steel on PRO-TEC's behalf. U. S. Steel, as PRO-TEC’s exclusive sales agent, is responsible for credit risk related to

those receivables. U. S. Steel also provides PRO-TEC marketing, selling and customer service functions. Payables to other related parties totaled $1 million for both periods ending December 31, 2022 and 2021, respectively.

Purchases from related parties for outside processing services provided by equity investees amounted to $27 million, $38 million and $90 million during 2022, 2021 and 2020, respectively. Purchases of iron ore pellets from related parties amounted to $131 million, $111 million and $78 million for the years ended December 31, 2022, 2021 and 2020, respectively.

Upon the acquisition of Big River Steel on January 15, 2021, there were related party payables of approximately $27 million for steel substrate sales from Big River Steel to U. S. Steel. After the acquisition, the related party payables became intercompany payables that are eliminated in consolidation.

Upon the acquisition of UPI on February 29, 2020 there were $135 million of related party receivables for prior sales of steel substrate from U. S. Steel to UPI. After the acquisition, the related party receivables became intercompany receivables that are eliminated in consolidation.

24. Leases

Operating lease assets consist primarily of office space, heavy mobile equipment used in our mining operations and facilities and equipment under operating service agreements for electricity generation and scrap processing. We also have operating lease assets for light mobile equipment and information technology assets. The Company also has short term leases related to transportation services for which we apply the short-term lease exception. Significant finance leases primarily consist of heavy mobile equipment used in our mining operations. Variable lease payments are primarily related to operating service agreements where payment is solely dependent on consumption of certain services, such as raw material and by-product processing. Most long-term leases include renewal options and, in certain leases, purchase options. Generally, we are not reasonably certain that these options will be exercised. We have residual value guarantees under certain light mobile equipment leases. There is no impact to our leased assets for residual value guarantees as the potential loss is not probable (see “Other Contingencies” in Note 26 for further details). We do not have material restrictive covenants associated with our leases or material amounts of sublease income. From time to time, U. S. Steel may enter into arrangements for the construction or purchase of an asset and then enter into a financing arrangement to lease the asset. U. S. Steel recognizes leased assets and liabilities under these arrangements when it obtains control of the asset.

The following table summarizes the lease amounts included in our Consolidated Balance Sheet as of December 31, 2022.

25. Restructuring and Other Charges

During 2022, the Company recorded restructuring and other charges of $48 million, which consists of charges of $30 million related to the planned disposition of a component within the Flat-Rolled segment, $23 million related to headcount reductions under a voluntary early retirement program (VERP) offered at USSK, a $9 million favorable adjustment to the expected exit costs of indefinitely idled facilities, and $4 million of severance-related charges at other facilities. Cash payments were made related to severance and exit costs of approximately $95 million.

During 2021, the Company recorded restructuring and other charges of $128 million, which consists of charges of $29 million for Great Lakes Works, charges of approximately $89 million related to the planned disposition of a component within the Flat-Rolled segment, and environmental-related charges at other facilities of $10 million. Cash payments were made related to severance and exit costs of approximately $58 million.

During 2020, the Company recorded restructuring and other charges of $138 million, which consists of charges of $66 million for the indefinite idling of a significant portion of Great Lakes Works, and our Keetac mining operations which was restarted in the fourth quarter, $25 million for the indefinite idling of Lorain Tubular Operations and Lone Star Tubular Operations, and $15 million and $32 million for employee benefit costs related to Company-wide headcount reductions and headcount reductions under a VERP offered at USSK, respectively. Cash payments were made related to severance and exit costs of approximately $169 million. A portion of these cash payments, approximately $38 million, were funded by the postretirement benefit trust (VEBA) per an agreement with the United Steelworkers of America.

Charges for restructuring and ongoing cost reduction initiatives are recorded in the period U. S. Steel commits to a restructuring or cost reduction plan, or executes specific actions contemplated by the plan and all criteria for liability recognition have been met. Charges related to the restructuring and cost reductions are reported in restructuring and other charges in the Consolidated Statements of Operations.

The activity in the accrued balances incurred in relation to restructuring during the years ended December 31, 2022, and December 31, 2021, were as follows:

26. Contingencies and Commitments

U. S. Steel is the subject of, or party to, a number of pending or threatened legal actions, contingencies and commitments involving a variety of matters, including laws and regulations relating to the environment. Certain of these matters are discussed below. The ultimate resolution of these contingencies could, individually or in the aggregate, be material to the Consolidated Financial Statements. However, management believes that U. S. Steel will remain a viable and competitive enterprise even though it is possible that these contingencies could be resolved unfavorably.

U. S. Steel accrues for estimated costs related to existing lawsuits, claims and proceedings when it is probable that it will incur these costs in the future and the costs are reasonably estimable.

Asbestos matters – As of December 31, 2022, U. S. Steel was a defendant in approximately 920 active cases involving approximately 2,510 plaintiffs. The vast majority of these cases involve multiple defendants. About 1,545, or approximately 62 percent, of these plaintiff claims are currently pending in jurisdictions which permit filings with massive numbers of plaintiffs. At December 31, 2021, U. S. Steel was a defendant in approximately 915 cases involving approximately 2,505 plaintiffs. Based upon U. S. Steel’s experience in such cases, it believes that the actual number of plaintiffs who ultimately assert claims against U. S. Steel will likely be a small fraction of the total number of plaintiffs.

The following table shows the number of asbestos claims in the current year and the prior two years:


Period ended	Opening Number of Claims	Claims Dismissed, Settled and Resolved	New Claims	Closing Number of Claims
December 31, 2020	2,390	240	295	2,445
December 31, 2021	2,445	200	260	2,505
December 31, 2022	2,505	230	235	2,510

The amount U. S. Steel accrues for pending asbestos claims is not material to U. S. Steel’s financial condition. However, U. S. Steel is unable to estimate the ultimate outcome of asbestos-related claims due to a number of uncertainties, including: (1) the rates at which new claims are filed, (2) the number of and effect of bankruptcies of other companies traditionally defending asbestos claims, (3) uncertainties associated with the variations in the litigation process from jurisdiction to jurisdiction, (4) uncertainties regarding the facts, circumstances and disease process with each claim, and (5) any new legislation enacted to address asbestos-related claims.

Further, U. S. Steel does not believe that an accrual for unasserted claims is required. At any given reporting date, it is probable that there are unasserted claims that will be filed against the Company in the future. The Company engages an outside valuation consultant to assist in assessing its ability to estimate an accrual for unasserted claims. This assessment is based on the Company's settlement experience, including recent claims trends. This analysis focuses on settlements made over the last several years as these claims are likely to best represent future claim characteristics. After review by the valuation consultant and U. S. Steel management, it was determined that the Company could not estimate an accrual for unasserted claims.

Despite these uncertainties, management believes that the ultimate resolution of these matters will not have a material adverse effect on U. S. Steel’s financial condition.

Environmental Matters – U. S. Steel is subject to federal, state, local and foreign laws and regulations relating to the environment. These laws generally provide for control of pollutants released into the environment and require responsible parties to undertake remediation of hazardous waste disposal sites. Penalties may be imposed for noncompliance. Changes in accrued liabilities for remediation activities where U. S. Steel is identified as a named party are summarized in the following table:

Accounts payable	$	32	$	65
Deferred credits and other noncurrent liabilities	94		93
Total	$	126	$	158

Expenses related to remediation are recorded in cost of sales and were $21 million and $47 million for the years ended December 31, 2022 and December 31, 2021, respectively. It is not currently possible to estimate the ultimate amount of all remediation costs that might be incurred or the penalties that may be imposed. Due to uncertainties inherent in remediation projects and the associated liabilities, it is reasonably possible that total remediation costs for active matters may exceed the accrued liabilities by as much as 20 to 35 percent.

Remediation Projects

U. S. Steel is involved in environmental remediation projects at or adjacent to several current and former U. S. Steel facilities and other locations that are in various stages of completion ranging from initial characterization through post-closure monitoring. Based on the anticipated scope and degree of uncertainty of projects, we categorize projects as follows:

(1) Projects with Ongoing Study and Scope Development – Projects which are still in the development phase. For these projects, the extent of remediation that may be required is not yet known, the remediation methods and plans are not yet developed, and/or cost estimates cannot be determined. Therefore, significant costs, in addition to the accrued liabilities for these projects, are reasonably possible. There are four environmental remediation projects where additional costs for completion are not currently estimable, but could be material. These projects are at Fairfield Works, Lorain Tubular, USS-UPI LLC (UPI) formerly known as USS-POSCO Industries and the former steelmaking plant at Joliet, Illinois. As of December 31, 2022, accrued liabilities for these projects totaled $1 million for the costs of studies, investigations, interim measures, design and/or remediation. It is reasonably possible that additional liabilities associated with future requirements regarding studies, investigations, design and remediation for these projects could be as much as $22 million to $36 million.

(2) Significant Projects with Defined Scope – Projects with significant accrued liabilities with a defined scope. As of December 31, 2022, there are three significant projects with defined scope greater than or equal to $5 million each, with a total accrued liability of $69 million. These projects are: Gary Resource Conservation and Recovery Act (RCRA) (accrued liability of $28 million), Duluth Works (accrued liability of $22 million) and the former Geneva facility (accrued liability of $19 million).

(3) Other Projects with a Defined Scope – Projects with relatively small accrued liabilities for which we believe that, while additional costs are possible, they are not likely to be significant, and also include those projects for which we do not yet possess sufficient information to estimate potential costs to U. S. Steel. There are three other environmental remediation projects which each had an accrued liability of between $1 million and $5 million. The total accrued liability for these projects at December 31, 2022 was $4 million. These projects have progressed through a significant portion of the design phase and material additional costs are not expected.

The remaining environmental remediation projects each have an accrued liability of less than $1 million each. The total accrued liability for these projects at December 31, 2022 was approximately $6 million. The Company does not foresee material additional liabilities for any of these sites.

Post-Closure Costs – Accrued liabilities for post-closure site monitoring and other costs at various closed landfills totaled $24 million at December 31, 2022 and were based on known scopes of work.

Administrative and Legal Costs – As of December 31, 2022, U. S. Steel had an accrued liability of $10 million for administrative and legal costs related to environmental remediation projects. These accrued liabilities were based on projected administrative and legal costs for the next three years and do not change significantly from year to year.

Capital Expenditures – For a number of years, U. S. Steel has made substantial capital expenditures to comply with various regulations, laws, and other requirements relating to the environment. Such capital expenditures totaled $43 million and $27 million In 2022 and 2021, respectively. U. S. Steel anticipates making additional such expenditures in the future, which may be material; however, the exact amounts and timing of such expenditures are uncertain because of the continuing evolution of specific regulatory requirements.

European Union (the EU) Environmental Requirements - Phase IV of the EU Emissions Trading System (the EU ETS) commenced on January 1, 2021 and will finish on December 31, 2030. The European Commission issued final approval of the updated 2021-2025 Slovak National Allocation table in February 2022. Subsequently, the Slovak Ministry of Environment allocated the full amount of 2022 free allowances totaling 6.3 million EUA to USSE in February and April 2022. As of December 31, 2022, we have pre-purchased approximately 2.1 million EUA totaling €147 million (approximately $157 million) to cover the expected 2022 and 2023 shortfall of emission allowances.

The EU’s Industrial Emissions Directive requires implementation of EU-determined best available techniques (BAT) for Iron and Steel production to reduce environmental impacts as well as compliance with BAT associated emission levels. Total capital expenditures for projects to comply with or go beyond BAT requirements were €138 million (approximately $147 million). These costs were partially offset by the EU funding received and may be mitigated over the next measurement periods if USSK complies with certain financial covenants, which are assessed annually. USSK complied with these covenants as of December 31, 2022. If we are unable to meet these covenants in the future, USSK might be required to provide additional collateral (e.g., bank guarantee) to secure 50 percent of the EU funding received.

Environmental indemnifications – Throughout its history, U. S. Steel has sold numerous properties and businesses and many of these sales included indemnifications and cost sharing agreements related to the assets that were divested. The amount of potential environmental liability associated with these transactions and properties is not estimable due to the nature and extent of the unknown conditions related to the properties divested and deconsolidated. Aside from the environmental liabilities already recorded as a result of these transactions due to specific environmental remediation activities and cases (included in the $126 million of accrued liabilities for remediation discussed above), there are no other known probable and estimable environmental liabilities related to these transactions.

Guarantees – The maximum guarantees of the indebtedness of unconsolidated entities of U. S. Steel totaled $7 million at December 31, 2022.

Other contingencies – Under certain operating lease agreements covering various equipment, U. S. Steel has the option to renew the lease or to purchase the equipment at the end of the lease term. If U. S. Steel does not exercise the purchase option by the end of the lease term, U. S. Steel guarantees a residual value of the equipment as determined at the lease inception date (totaling approximately $13 million at December 31, 2022). No liability has been recorded for these guarantees as the potential loss is not probable.

The Company's BR2 project in Osceola, Arkansas qualifies for financing and related economic incentives associated with the acquisition, development, construction and operation of the facility. These incentives consist of advance lump-sum payments which are included in deferred credits and other noncurrent liabilities on the Consolidated Balance Sheet. In March 2022, the Company received a lump-sum payment of approximately $82 million as proceeds from the sale of a portion of expected future tax credits to be earned by the Company under the State of Arkansas's Recycling Tax Credit program. These funds are to be used primarily for the acquisition of project related equipment, however they may also be used for the training and development of new employees hired for the project. The Company is contingently liable for certain repayment penalties if the Company fails to meet certain employment requirements in any given period. In April 2022, the Company received a $3 million grant from Mississippi County, Arkansas, and in May 2022, the Company received a $50 million grant from the State of Arkansas Quick Action Closing Fund. Both grants pertain to the reimbursement of qualifying project costs. For each of these incentives and grants, the balance of deferred income will be recognized into Other gains, net in the accompanying Consolidated Statements of Operations on a systematic basis over the periods in which the Company earns the granted funds by complying with the investment and employment requirements of the grant programs.

Insurance – U. S. Steel maintains insurance for certain property damage, equipment, business interruption and general liability exposures; however, insurance is applicable only after certain deductibles and retainages. U. S. Steel is self-insured for certain other exposures including workers’ compensation (where permitted by law) and auto liability. Liabilities are recorded for workers’ compensation and personal injury obligations. Other costs resulting from losses under deductible or retainage amounts or not otherwise covered by insurance are charged against income upon occurrence.

U. S. Steel uses surety bonds, trusts and letters of credit to provide whole or partial financial assurance for certain obligations such as workers’ compensation. The total amount of active surety bonds, trusts and letters of credit being used for financial assurance purposes was approximately $178 million as of December 31, 2022, which reflects U. S. Steel’s maximum exposure under these financial guarantees, but not its total exposure for the underlying obligations. A significant portion of our trust arrangements and letters of credit are collateralized by the Credit Facility Agreement. The remaining trust arrangements and letters of credit are collateralized by restricted cash. Restricted cash, which is recorded in other

current and noncurrent assets, totaled $35 million and $78 million at December 31, 2022 and December 31, 2021 respectively.

Capital Commitments – At December 31, 2022, U. S. Steel’s contractual commitments to acquire property, plant and equipment totaled $2.235 billion.

Contractual Purchase Commitments – U. S. Steel is obligated to make payments under contractual purchase commitments, including unconditional purchase obligations. Payments for contracts with remaining terms in excess of one year are summarized below (in millions):


2023	2024	2025	2026	2027	Later years	Total
$477	$258	$352	$285	$267	$394	$2,033

The majority of U. S. Steel’s unconditional purchase obligations relate to the supply of industrial gases, and certain energy and utility services with terms ranging from two to 13 years. Unconditional purchase obligations also include coke and steam purchase commitments related to a coke supply agreement with Gateway Energy & Coke Company LLC (Gateway) under which Gateway is obligated to supply a minimum volume of the expected targeted annual production of the heat recovery coke plant, and U. S. Steel is obligated to purchase the coke from Gateway at the contract price. As of December 31, 2022, if U. S. Steel were to terminate the agreement, it may be obligated to pay in excess of $24 million.

Total payments relating to unconditional purchase obligations were approximately $850 million in 2022, $767 million in 2021 and $553 million in 2020.

27. Common Stock Issued and Repurchased

U. S. Steel repurchased 37.6 million shares and 6.6 million shares of common stock for approximately $849 million and $150 million under these programs during 2022 and 2021, respectively.

In February 2021, U. S. Steel issued 48.3 million shares of common stock for net proceeds of approximately $790 million.

In June 2020, U. S. Steel issued 50 million shares of common stock for net proceeds of approximately $410 million.

Equity Compensation Plan Information


Plan Category	(1) Number of securities to be issued upon exercise of outstanding options, warrants and rights	(2) Weighted-average exercise price of outstanding options, warrants and rights	(3) Number of securities remaining available for future issuance under equity compensation plans excluding securities reflected in Column (1) (b)
Equity compensation plans approved by security holders (a)	10,700,781	$26.88	9,080,478
Equity compensation plans not approved by security holders(c)	—	(one for one)	—
Total	10,700,781	—	9,080,478

(For more information, see Note 15 to the Consolidated Financial Statements).

The calculation in column (2) does not include the Common Stock Units since the weighted average exercise price for Common Stock Units is one for one; that is, one share of common stock will be given in exchange for each unit of such phantom stock accumulated through the date of the director’s retirement. Also, the calculation in column (2) does not include the performance awards since the shares issued for performance awards can range from zero for one to two for one; that is, performance awards may result in up to 5,517,086 of common stock being issued (two for one), or some lesser number of shares (including zero shares of common stock issued), depending upon the Corporation’s common stock performance versus that of a peer group of companies or the Corporation's return on capital employed performance over a performance period.

(c)At December 31, 2022, U. S. Steel had no securities remaining for future issuance under equity compensation plans that had not been approved by security holders.

The weighted average exercise price for Common Stock Units in column (2) is one for one; that is, one share of common stock will be given in exchange for each unit of phantom stock upon the director’s retirement from the Board of Directors. All future grants under this amended plan/program will count as shares issued under to the 2016 Omnibus Incentive Compensation Plan, as amended and restated, a stockholder approved plan.
