PART I

ITEM 1.    Business

OVERVIEW

We were founded in 1919 as Cummins Engine Company, a corporation in Columbus, Indiana and one of the first diesel engine manufacturers. In 2001, we changed our name to Cummins Inc. We are a global power leader that designs, manufactures, distributes and services diesel, natural gas, electric and hybrid powertrains and powertrain-related components including filtration, aftertreatment, turbochargers, fuel systems, controls systems, air handling systems, automated transmissions, electric power generation systems, batteries, electrified power systems, hydrogen production and fuel cell products. We sell our products to original equipment manufacturers (OEMs), distributors, dealers and other customers worldwide. We serve our customers through a network of over 500 wholly-owned, joint venture and independent distributor locations and over 9,000 Cummins certified dealer locations with service to approximately 190 countries and territories.

COVID-19

The outbreak of the coronavirus disease of 2019 (COVID-19) spread throughout the world and became a global pandemic with the resultant economic impacts evolving into a worldwide recession. The pandemic triggered a significant downturn in our markets globally, which continued to unfavorably impact market conditions throughout 2020 and these challenging market conditions could continue for an extended period of time. In an effort to contain the spread of COVID-19, maintain the well-being of our employees and stakeholders, match the reduced demand from our customers and in accordance with governmental requirements, we closed or partially shut down certain office, manufacturing, distribution and technical center facilities around the world in March 2020. Although most of our manufacturing, distribution and technical center facilities re-opened early in the second quarter of 2020, some operated at reduced capacities, most of our global office buildings remained closed through the remainder of 2020. Despite many of our markets recovering in the second half of 2020, the ongoing spread of the virus prior to widespread vaccination presents several risks to our business, especially in the first half of 2021.

COVID-19 vaccines are currently being administered around the world with the hope that the majority of the population will have access to the vaccine by the middle of 2021. If the distribution and the effectiveness of the vaccine are consistent with current government and health organization estimates, we anticipate the vaccine will mitigate the spread of the virus by the end of 2021 and allow a return to more normal operations in the second half of the year.

OPERATING SEGMENTS

We have five complementary operating segments: Engine, Distribution, Components, Power Systems and New Power. These segments share technology, customers, strategic partners, brand recognition and our distribution network in order to compete more efficiently and effectively in their respective markets. In each of our operating segments, we compete worldwide with a number of other manufacturers and distributors that produce and sell similar products. Our products primarily compete on the basis of performance, price, total cost of ownership, fuel economy, emissions compliance, speed of delivery, quality and customer support.

We use segment earnings or losses before interest expense, income taxes, depreciation and amortization and noncontrolling interests (EBITDA) as the primary basis for the Chief Operating Decision Maker to evaluate the performance of each of our reportable operating segments. We believe EBITDA is a useful measure of our operating performance as it assists investors and debt holders in comparing our performance on a consistent basis without regard to financing methods, capital structure, income taxes or depreciation and amortization methods, which can vary significantly depending upon many factors. See Note 22, "OPERATING SEGMENTS," to the Consolidated Financial Statements for additional information and a reconciliation of our segment information to the corresponding amounts in our Consolidated Statements of Net Income.

See further discussion of our distribution network under the Distribution segment section above.

Non-Wholly-Owned Subsidiaries

We have a majority voting interest in Eaton Cummins Automated Transmission Technologies (ECJV) by virtue of a tie-breaking vote on the joint venture’s board of directors. ECJV develops and supplies automated transmissions for the heavy-duty commercial vehicle market.

We have a controlling interest in Cummins India Ltd. (CIL), which is a publicly listed company on various stock exchanges in India. CIL produces medium-duty, heavy-duty and high-horsepower diesel engines, generators for the Indian and export markets and natural gas spark-ignited engines for power generation, automotive and industrial applications. CIL also has distribution and power generation operations.

In the third quarter of 2019, we formed a joint venture with L'Air Liquide S.A. via the purchase of Hydrogenics Corporation, which was consolidated and included in our New Power segment. The Hydrogen Company, a wholly-owned subsidiary of L'Air Liquide S.A., maintains a 19 percent noncontrolling interest in Hydrogenics Corporation. See Note 20, "ACQUISITIONS", to the Consolidated Financial Statements for additional information.

SUPPLY

The performance of the end-to-end supply chain, extending through to our suppliers, is foundational to our ability to meet customers' expectations and support long-term growth. We are committed to having a robust strategy for how we select and manage our suppliers to enable a market focused supply chain. This requires us to continuously evaluate and upgrade our supply base, as necessary, to ensure we are meeting the needs of our customers.

We use a combination of proactive and reactive methodologies to enhance our understanding of supply base risks which guide the development of risk monitoring and sourcing strategies. Our category strategy process (a process designed to create the most value for the company) supports the review of our long-term needs and guides decisions on what we make internally and what we purchase externally. For the items we decide to purchase externally, the strategies also identify the suppliers we should partner with long-term to provide the best technology, the lowest total cost and highest supply chain performance. We design and/or manufacture our strategic components used in or with our engines and power generation units and New Power products. Key suppliers are managed through long-term supply and cost sharing agreements that assure capacity, delivery, quality and cost requirements are met over an extended period.

Other important elements of our sourcing strategy include:

• working with suppliers to measure and improve their environmental footprint;

• selecting and managing suppliers to comply with our supplier code of conduct; and

• assuring our suppliers comply with our prohibited and restricted materials policy.

PATENTS AND TRADEMARKS

We own or control a significant number of patents and trademarks relating to the products we manufacture. These patents and trademarks were granted and registered over a period of years. Although these patents and trademarks are generally considered beneficial to our operations, we do not believe any patent, group of patents or trademark (other than our leading brand house trademarks) is significant to our business.

SEASONALITY

While individual product lines may experience modest seasonal variation in production, there is no material effect on the demand for the majority of our products on a quarterly basis with the exception that our Power Systems segment normally experiences seasonal declines in the first quarter due to general declines in construction spending during this period.

LARGEST CUSTOMERS

We have thousands of customers around the world and have developed long-standing business relationships with many of them. PACCAR is our largest customer, accounting for 15 percent of our consolidated net sales in 2020, 17 percent in 2019 and 15 percent in 2018. We have long-term supply agreements with PACCAR for our heavy-duty and medium-duty engines and aftertreatment systems. While a significant number of our sales to PACCAR are under long-term supply agreements, these agreements provide for particular engine requirements for specific vehicle models and not a specific volume of engines or aftertreatment systems. PACCAR is our only customer accounting for more than 10 percent of our net sales in 2020. The loss of this customer or a significant decline in the production level of PACCAR vehicles that use our engines would have an adverse effect on our results of operations and financial condition. We have been an engine supplier to PACCAR for 76 years. A summary of principal customers for each operating segment is included in our segment discussion.

In addition to our agreement with PACCAR, we have long-term heavy-duty and medium-duty engine and aftertreatment system supply agreements with Navistar and Daimler. We also have an agreement with Chrysler to supply engines for its Ram trucks. Collectively, our net sales to these four customers, including PACCAR, were 32 percent of our consolidated net sales in 2020, 37 percent in 2019 and 35 percent in 2018. Excluding PACCAR, net sales to any single customer were less than 7 percent of our consolidated net sales in 2020, less than 9 percent in 2019 and less than 9 percent in 2018. These agreements contain standard purchase and sale agreement terms covering engine, aftertreatment and engine parts pricing, quality and delivery commitments, as well as engineering product support obligations. The basic nature of our agreements with OEM customers is that they are long-term price and operations agreements that help assure the availability of our products to each customer through the duration of the respective agreements. Agreements with most OEMs contain bilateral termination provisions giving either party the right to terminate in the event of a material breach, change of control or insolvency or bankruptcy of the other party.

BACKLOG

We have supply agreements with some truck and off-highway equipment OEMs, however most of our business is transacted through open purchase orders. These open orders are historically subject to month-to-month releases and are subject to cancellation on reasonable notice without cancellation charges and therefore are not considered firm. At December 31, 2020, we did not have any significant backlogs.

RESEARCH AND DEVELOPMENT

In 2020, we continued to invest in future critical technologies and products. We will continue to make investments to develop new products and improve our current technologies to meet future emission requirements around the world and improve fuel economy performance of diesel and natural gas-powered engines and related components as well as development activities around fully electric, hybrid and hydrogen power solutions and hydrogen production.

Our research and development programs are focused on product improvements, product extensions, innovations and cost reductions for our customers. Research and development expenditures include salaries, contractor fees, building costs, utilities, testing, technical IT, administrative expenses and allocation of corporate costs and are expensed, net of contract reimbursements, when incurred. From time to time, we enter into agreements with customers and government agencies to fund a portion of the research and development costs of a particular project. When not associated with a sales contract, we generally account for these reimbursements as an offset to the related research and development expenditure. Research and development expenses, net of contract reimbursements, were $903 million in 2020, $998 million in 2019 and $894 million in 2018. Contract reimbursements were $86 million, $90 million and $120 million in 2020, 2019 and 2018, respectively.

ENVIRONMENTAL SUSTAINABILITY

We are committed to making people's lives better by powering a more prosperous world. That prosperity includes strong communities, robust business and environmental sustainability.

11

The highest level of accountability for our climate-related risks and opportunities is with the Safety, Environment and Technology (SET) Committee of the Board of Directors (the Board). The Action Committee for Environmental Sustainability meets monthly and reports to the Chairman and to the SET Committee at least annually.

In late 2019, we introduced PLANET 2050, a sustainability strategy focused on three priority areas: addressing climate change and air emissions, using natural resources in the most sustainable way and improving communities. The strategy includes eight specific goals to achieve by 2030, including science-based carbon dioxide reduction targets for newly sold products and facilities, as well as aspirational targets for 2050. We are currently evaluating how the new goals will be integrated into business planning and will report on progress beginning in 2022.

Our Sustainability Progress Report for 2019/2020 reports on environmental sustainability goals and commitments from our 2014 plan as well as other key environmental and climate metrics and targets. The 2014 plan goals were as follows:

•partnering with customers to improve the fuel efficiency of our products in use, targeting an annual run-rate reduction of 3.5 million metric tons of carbon dioxide;

•achieving a 32 percent energy intensity reduction from company facilities by the end of 2020 (using a baseline year of 2010) and increasing the portion of electricity we use derived from renewable sources;

•reducing direct water use by 50 percent adjusted for hours worked and achieving water neutrality at 15 sites by the end of 2020;

•increasing our recycling rate from 88 percent to 95 percent and achieving zero disposal at 30 sites by the end of 2020 and

•utilizing the most efficient methods and modes to move goods across our network to reduce carbon dioxide per kilogram of goods moved by 10 percent by the end of 2020.

Our progress through the end of 2020 will be summarized in our Sustainability Progress Report to be published later in 2021. This report is not incorporated by reference into this filing.

The most recent Sustainability Progress Report and prior reports, as well as a Data Book of more detailed environmental data in accordance with the Global Reporting Initiative's Standard core compliance designation, are available on our website at www.cummins.com. Our annual submission to the Carbon Disclosure Project (CDP) for climate change and water are also available on the website. The climate submission provides information on our scenario planning exercise for climate and other risks as requested by CDP. We also published our first report in accordance with the Sustainability Accounting Standards Board in 2020. These reports and data book are not incorporated into this Form 10-K by reference.

We continue to articulate our positions on key public policy issues and on a wide range of environmental issues. We are actively engaged with regulatory, industry and other stakeholder groups around the world as greenhouse gases (GHG) and fuel efficiency standards become more prevalent globally. We were named number 24 in Newsweek's Most Responsible Companies ranking, number 50 among Barron's Top 100 Most Sustainable Companies as well as named to the Dow Jones North American Sustainability Index for the fifteenth consecutive year in 2020.

ENVIRONMENTAL COMPLIANCE

Product Certification and Compliance

Our engines are subject to extensive statutory and regulatory requirements that directly or indirectly impose standards governing emissions and noise. Over the past several years we have increased our global environmental compliance presence and expertise to understand and meet emerging product environmental regulations around the world. Our ability to comply with these and future emission standards is an essential element in maintaining our leadership position in regulated markets. We have made, and will continue to make, significant capital and research expenditures to comply with these standards.

We strive to be a leader in developing and implementing technologies that provide customers with the highest performing products while minimizing the impact on the environment, and we have a long history of working with governments and regulators to achieve these goals. We remain committed to ensuring our products meet all current and future emission standards and delivering value to our customers.

Formed in 2019, the Product Compliance and Regulatory Affairs team leads both engine emissions certification and compliance and regulatory affairs initiatives. This organization is led by the Vice President - Product Compliance and Regulatory Affairs who reports directly to the Chief Executive Officer, and the new Vice President joins the Cummins Executive Team and Cummins Leadership Team. The focus of this organization is to strengthen our ability to design great products that help our customers win while ensuring compliance with increasingly challenging global emission regulations. The organization also works to enhance our collaboration with

12

the agencies setting the direction and regulations of emissions to best ensure we are meeting every expectation today while planning for future changes.

Following conversations with the U.S. Environmental Protection Agency (EPA) and California Air Resources Board (CARB) regarding certification for the engines in the 2019 RAM 2500 and 3500 trucks, we made the decision to review our certification process and compliance with emission standards. This review is being conducted with external advisers to ensure the certification and all of our processes for our pick-up truck applications are consistent with our internal policies, engineering standards and applicable laws. In addition, we voluntarily disclosed our formal internal review to the regulators and to other government agencies, the Department of Justice (DOJ) and the Securities and Exchange Commission (SEC), and worked cooperatively with them to ensure a complete and thorough review. We fully cooperated with the DOJ's and the SEC's information requests and inquiries and, based on recent communications with these agencies, we do not expect further inquiries. See Note 14, "COMMITMENTS AND CONTINGENCIES," to the Consolidated Financial Statements for additional information.

Engine Certifications

Our engines are certified globally through various categories within on-highway and off-highway applications. Regulations in these categories typically control nitrous oxides (NOx), particulate matter (PM) and GHG. The current on-highway NOx and PM emission standards came into effect in India on April 1, 2020, (BS VI), China on July 1, 2019, (NS VI), the EU on January 1, 2013, (Euro VI) and on January 1, 2010, for the EPA. To meet these regulations, mid-range and heavy-duty engines for India, China, EU and EPA require NOx aftertreatment. NOx reduction is achieved by an integrated technology solution comprised of the XPI High Pressure Common Rail fuel system, SCR technology (in some cases), next-generation cooled EGR, advanced electronic controls, proven air handling and the Cummins Diesel Particulate Filter (DPF). The Ministry of Road Transport and Highways, Ministry of Ecology and Environment, EU, EPA and CARB have certified that our engines meet the current emission requirements. Emission standards in international markets, including Japan, Mexico, Australia, Brazil and Russia are becoming more stringent. We believe that our experience in meeting the EU and EPA emission standards leaves us well positioned to take advantage of opportunities in these markets as the need for emission control capability grows.

In 2013, we certified to EPA's first ever GHG regulations for on-highway medium and heavy-duty engines. Additionally, the EPA 2013 regulations added the requirement of on-board diagnostics, which were introduced on the ISX 15 in 2010, across the full on-highway product line while maintaining the same near-zero emission levels of NOx and PM required in 2010. On-board diagnostics provide enhanced service capability with standardized diagnostic trouble codes, service tool interface, in-cab warning lamp and service information availability. The new GHG and fuel-efficiency regulations were required for all heavy-duty diesel and natural gas engines beginning in January 2014. Our GHG certification was the first engine certificate issued by the EPA and uses the same proven base engine with the XPI fuel system, variable geometry turbocharger (VGTTM) and Cummins aftertreatment system with DPF and SCR technology. Application of these engines and aftertreatment technologies continues in our products that comply with the 2021 GHG regulations.

Our off-highway engines designed for Tier 4 / Stage V standards were based on our extensive on-highway experience developing SCR, high pressure fuel systems, DPF and VGTTM. Our products offer low fuel consumption, high torque rise and power output, extended maintenance intervals, reliable and durable operation and a long life to overhaul period, all while meeting the most stringent emission standards in the industrial market. Our off-highway products power multiple applications including construction, mining, marine, agriculture, rail, defense and oil and gas and serve a global customer base. The current EPA Tier 4 off-highway emission standards came into effect between 2013-2015 for all engine power categories. The current EU Stage V off-highway emission standards became effective in 2019 for certain engine power categories and were completely effective January 2021 for all remaining categories.

Other Environmental Statutes and Regulations

Expenditures for environmental control activities and environmental remediation projects at our facilities in the U.S. have not been a substantial portion of our annual expenses and are not expected to be material in 2021. We believe we are in compliance in all material respects with laws and regulations applicable to our plants and operations.

In the U.S., pursuant to notices received from federal and state agencies and/or defendant parties in site environmental contribution actions, we have been identified as a potentially responsible party under the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended or similar state laws, at fewer than 20 waste disposal sites.

Based upon our experiences at similar sites we believe that our aggregate future remediation costs will not be material. We have established accruals that we believe are adequate for our expected future liability with respect to these sites. In addition, we have several other sites where we are working with governmental authorities on remediation projects. The costs for these remediation projects are not expected to be material.

HUMAN CAPITAL RESOURCES

At December 31, 2020, we employed approximately 57,825 persons worldwide. Approximately 20,279 of our employees worldwide are represented by various unions under collective bargaining agreements that expire between 2021 and 2025.

Throughout our company’s 100-year history, we always recognized that people drive the strength of our business and our ability to effectively serve our clients and sustain our competitive position. We are focused on harmonizing our approach to talent to provide seamless opportunities and better experiences to our employees around the world. The disruptive events of 2020 gave even greater importance for us to complete the strategic work in Human Resources that calls for our company to “Inspire and Encourage All Employees to Reach Their Full Potential.” This strategy has key focus areas: creating a diverse and inclusive work environment; engaging employees and their families in improving wellness; developing self-aware and effective leaders; and extending our talent management philosophies in performance management, compensation management, competency building, and access to development opportunities to all employees.

Leadership and Talent Management

Managing our human capital resources is a key focus of the company. In 2020, the Board recast our Compensation Committee as the Talent Management and Compensation Committee to reflect the Board’s commitment to overseeing and providing guidance to our leadership team in this important work.

We strive to create a leadership culture that begins with authentic leaders who create an outstanding place to work by encouraging all employees to achieve their full potential. We encourage leaders to connect our people and their work to our mission, vision, values, brand promise and strategies of the company, motivating and giving them a higher sense of purpose. We have developed leadership and employee development programs for employees ranging from the manufacturing floor and technicians through middle management and executive development. When an individual joins Cummins, we are committed to providing both that employee and their manager with the tools and resources to manage their career and navigate in a large global organization. Through our Talent Management strategy our goal is to ensure all employees have access to the development and career opportunities that a global company enables.

Competitive Pay and Benefits

To attract and retain the best employees, we focus on providing competitive pay and benefits. Our programs target the market for competitiveness and sustainability while ensuring that we honor our core values. We provide benefit programs with the goal of improving physical, mental and financial wellness of our employees throughout their lifetime. Some examples include base and variable pay, medical, paid time off, retirement saving plans and employee stock purchase plans.

When designing our base pay compensation ranges, we do market analysis to be sure ranges are current and our employees are advancing their earning potential. We also do annual compensation studies to assess market movement, pay equity and living wages. For example, in 2018, we conducted a living wage analysis globally to ensure our employees were making a living wage in the countries they live and work. We incorporated this living wage assessment into our annual compensation structure to ensure that current and new hires never fall below this threshold. In the U.S. for example, the living wage in 2019 was $15 per hour, although most positions pay more than that. We continually review wages globally to ensure we are fair, equitable, competitive and can attract and retain the best talent.

We also provide diverse benefit programs that are aligned with our values and focused on supporting employees and their families based on their unique needs, some of which are: tiered health care cost so that more junior employees pay less for their premiums; paid parental leave for primary and secondary caregivers; advanced medical services from clinicians to support complex health care needs and employee assistance programs with diverse providers that can meet a range of employee needs from race related trauma to financial planning to transgender transition support.

Employee Safety and Wellness

Cummins is committed to being world-class in health and safety. We strive to ensure a workplace with zero incidents. We are committed to removing conditions that cause personal injury or occupational illness and we make decisions and promote behaviors that protect others from risk of injury. We publicly disclose metrics on our rate of recordable injuries, our rate of lost workdays due to injury and the rate of injuries involving contractors.

Our response to the COVID-19 global pandemic illustrated our commitment to safety. To support both our customers and communities, we made keeping employees safe our top priority. Most of our employees who can work from home have been doing so since the outbreak of the pandemic and we have provided them with the tools and support to do so. This allowed us to focus resources

14

and investments on our engineering and production facilities. In those facilities, we have taken many steps to protect the health and safety of our people, including:

•Mandatory health screenings at our plants and facilities;

•Personal protective equipment for frontline employees;

•Masks required inside open plants and facilities;

•Redesigned exits, entrances and production lines to encourage social distancing;

•Enhanced cleaning protocols before, during and after shifts;

•Expanded healthcare and leave programs to support employees and their families; and

•Manufacturing our own face masks to provide to our employees free of charge.

Diversity, Equity and Inclusion

Diversity, equity and inclusion at all levels of the company are critical to our ability to innovate, to win in the marketplace and to create sustainable success. Having diverse, equitable and inclusive workplaces allows us to attract and retain the best employees to deliver results for our shareholders. This is exemplified by the composition of the Board of which 4 of 12 directors are female and 4 of 12 directors are ethnically diverse. In addition, 50 percent of our executive team is female and 40 percent of our leadership team is female. We disclose publicly the percentage of women in supervisory roles and the overall workforce. We also launched several initiatives to increase representation of minorities in the workplace. We have created a Global Inclusion Leadership Council to oversee more than 100 employee resource groups around the world to provide opportunities to employees from all backgrounds for leadership training, cross cultural learning and professional development. In 2020, we launched Cummins Advocating for Racial Equity (CARE), which seeks to drive a sustainable impact in dismantling institutional racism and creating systemic equity.

ITEM 1A. Risk Factors

Set forth below and elsewhere in this Annual Report on Form 10-K are some of the principal risks and uncertainties that could cause our actual business results to differ materially from any forward-looking statements contained in this Report and could individually, or in combination, have a material adverse effect on our results of operations, financial position and cash flows. These risk factors should be considered in addition to our cautionary comments concerning forward-looking statements in this Report, including statements related to markets for our products and trends in our business that involve a number of risks and uncertainties. Our separate section above, "CAUTIONARY STATEMENTS REGARDING FORWARD-LOOKING INFORMATION," should be considered in addition to the following statements.

GOVERNMENT REGULATION

We are conducting a formal internal review of our emission certification process and compliance with emission standards with respect to our pick-up truck applications and are working with the EPA and CARB to address their questions about these applications. The results of this formal review and regulatory processes, or the discovery of any noncompliance issues, could have a material adverse impact on our results of operations and cash flows.

We previously announced that we are conducting a formal internal review of our emissions certification process and compliance with emission standards with respect to all of our pick-up truck applications, following conversations with the EPA and CARB regarding certification of our engines for model year 2019 RAM 2500 and 3500 trucks. During conversations with the EPA and CARB about the effectiveness of our pick-up truck applications, the regulators raised concerns that certain aspects of our emissions systems may reduce the effectiveness of our emissions control systems and thereby act as defeat devices. As a result, our internal review focuses, in part, on the regulators’ concerns. We are working closely with the regulators to enhance our emissions systems to improve the effectiveness of all of our pick-up truck applications and to fully address the regulators’ requirements. Based on discussions with the regulators, we have developed a new calibration for the engines in model year 2019 RAM 2500 and 3500 trucks that has been included in all engines shipped since September 2019. During our discussions, the regulators have asked us to look at other model years and other engines. We will continue to work together closely with the relevant regulators to develop and implement recommendations for improvement as part of our ongoing commitment to compliance.

Due to the continuing nature of the formal review, our ongoing cooperation with the regulators and the presence of many unknown facts and circumstances, we are not yet able to estimate the financial impact of these matters. It is possible that the consequences of any remediation plans resulting from our formal review and these regulatory processes could have a material adverse impact on our results of operations and cash flows in the periods in which these emissions certification issues are addressed.

Our products are subject to extensive statutory and regulatory requirements that can significantly increase our costs and, along with increased scrutiny from regulatory agencies and unpredictability in the adoption, implementation and enforcement of increasingly stringent and fragmented emission standards by multiple jurisdictions around the world, could have a material adverse impact on our results of operations, financial condition and cash flows.

Our engines are subject to extensive statutory and regulatory requirements governing emissions and noise, including standards imposed by the EPA, the EU, state regulatory agencies (such as the CARB) and other regulatory agencies around the world. Regulatory agencies are making certification and compliance with emissions and noise standards more stringent and subjecting diesel engine products to an increasing level of scrutiny. The discovery of noncompliance issues could have a material adverse impact on our results of operations, financial condition and cash flows.

Developing engines and components to meet more stringent and changing regulatory requirements, with different implementation timelines and emission requirements, makes developing engines efficiently for multiple markets complicated and could result in substantial additional costs that may be difficult to recover in certain markets. While we have met previous deadlines, our ability to comply with existing and future regulatory standards will be essential for us to maintain our competitive position in the engine applications and industries we serve. The successful development and introduction of new and enhanced products in order to comply with new regulatory requirements are subject to other risks, such as delays in product development, cost over-runs and unanticipated technical and manufacturing difficulties.

In addition to these risks, the nature and timing of government implementation and enforcement of increasingly stringent emission standards in our worldwide markets are unpredictable and subject to change. Any delays in implementation or enforcement could result in a loss of our competitive advantage and could have a material adverse impact on our results of operations, financial condition and cash flows.

17

We operate our business on a global basis and policy changes affecting international trade could adversely impact the demand for our products and our competitive position.

We manufacture, sell and service products globally and rely upon a global supply chain to deliver the raw materials, components, systems and parts that we need to manufacture and service our products. Changes in government policies on foreign trade and investment can affect the demand for our products and services, cause non-U.S. customers to shift preferences toward domestically manufactured or branded products and impact the competitive position of our products or prevent us from being able to sell products in certain countries. Our business benefits from free trade agreements, such as the new United States-Mexico-Canada Agreement and the U.S. trade relationship with China, Brazil and France and efforts to withdraw from, or substantially modify such agreements or arrangements, in addition to the implementation of more restrictive trade policies, such as more detailed inspections, higher tariffs (including, but not limited to, additional tariffs on the import of steel or aluminum), import or export licensing requirements, exchange controls or new barriers to entry, could adversely impact our production costs, customer demand and our relationships with customers and suppliers. Any of these consequences could have a material adverse effect on our results of operations, financial condition and cash flows.

The U.K.’s exit from the European Union (EU) could materially and adversely impact our results of operations, financial condition and cash flows.

On January 31, 2020, the U.K. exited from the EU (BREXIT). Additionally, the results of the U.K.’s BREXIT caused, and may continue to cause, volatility in global stock markets, currency exchange rate fluctuations and global economic uncertainty. Although it is unknown what the terms of the U.K.’s future relationship with the EU will be, it is possible that there will be higher tariffs or greater restrictions on imports and exports between the U.K. and the EU and increased regulatory complexities. The effects of BREXIT will depend on any agreements the U.K. makes to retain access to EU markets either during a transitional period or on a permanent basis. These measures could potentially disrupt our supply chain, including delays of imports and exports, limited access to human capital within some of the target markets and jurisdictions in which we operate and adverse changes to tax benefits or liabilities in these or other jurisdictions. In addition, BREXIT could lead to legal uncertainty and potentially divergent national laws and regulations, including with respect to emissions and similar certifications granted to us by the EU, as the U.K. determines which EU laws to replace or replicate. Any of these effects of BREXIT, among others, could have a material adverse impact on our results of operations, financial condition and cash flows.

Unanticipated changes in our effective tax rate, the adoption of new tax legislation or exposure to additional income tax liabilities could adversely affect our profitability.

We are subject to income taxes in the U.S. and numerous international jurisdictions. Our income tax provision and cash tax liability in the future could be adversely affected by changes in earnings in countries with differing statutory tax rates, changes in the valuation of deferred tax assets and liabilities, changes in tax laws and the discovery of new information in the course of our tax return preparation process. The carrying value of deferred tax assets, which are predominantly in the U.S., is dependent on our ability to generate future taxable income in the U.S. We are also subject to ongoing tax audits. These audits can involve complex issues, which may require an extended period of time to resolve and can be highly judgmental. Tax authorities may disagree with certain tax reporting positions taken by us and, as a result, assess additional taxes against us. We regularly assess the likely outcomes of these audits in order to determine the appropriateness of our tax provision. The amounts ultimately paid upon resolution of these or subsequent tax audits could be materially different from the amounts previously included in our income tax provision and, therefore, could have a material impact on our tax provision.

Our global operations are subject to laws and regulations that impose significant compliance costs and create reputational and legal risk.

Due to the international scope of our operations, we are subject to a complex system of commercial and trade regulations around the world. Recent years have seen an increase in the development and enforcement of laws regarding trade compliance and anti-corruption, such as the U.S. Foreign Corrupt Practices Act and similar laws from other countries, as well as new regulatory requirements regarding data privacy, such as the European Union General Data Protection Regulation. Our numerous foreign subsidiaries, affiliates and joint venture partners are governed by laws, rules and business practices that differ from those of the U.S. The activities of these entities may not comply with U.S. laws or business practices or our Code of Business Conduct. Violations of these laws may result in severe criminal or civil sanctions, could disrupt our business and result in an adverse effect on our reputation, business and results of operations, financial condition and cash flows. We cannot predict the nature, scope or effect of future regulatory requirements to which our operations might be subject or the manner in which existing laws might be administered or interpreted.

Our operations are subject to increasingly stringent environmental laws and regulations.

Our plants and operations are subject to increasingly stringent environmental laws and regulations in all of the countries in which we operate, including laws and regulations governing air emission, discharges to water and the generation, handling, storage,

18

transportation, treatment and disposal of waste materials. While we believe that we are in compliance in all material respects with these environmental laws and regulations, there can be no assurance that we will not be adversely impacted by costs, liabilities or claims with respect to existing or subsequently acquired operations, under either present laws and regulations or those that may be adopted or imposed in the future. We are also subject to laws requiring the cleanup of contaminated property. If a release of hazardous substances occurs at or from any of our current or former properties or at a landfill or another location where we have disposed of hazardous materials, we may be held liable for the contamination and the amount of such liability could be material.

Future bans or limitations on the use of diesel-powered vehicles or other applications could have a material adverse impact on our business over the long term.

In an effort to limit greenhouse gas emissions and combat climate change, multiple countries and cities have announced that they plan to implement a ban on the use in their countries or cities of diesel-powered products in the near or distant future. These countries include China, India and Germany. In addition, California government officials have called for the state to phase out sales of diesel-powered certain vehicles by 2035. To the extent that these types of bans are actually implemented in the future on a broad basis, or in one or more of our key markets, our diesel business over the long-term could experience material adverse impacts.

BUSINESS CONDITIONS / DISRUPTIONS

We are vulnerable to supply shortages from single-sourced suppliers, including suppliers that may be impacted by the COVID-19 pandemic, and any delay in receiving critical supplies could have a material adverse effect on our results of operations, financial condition and cash flows.

We single source a significant number of parts and raw materials critical to our business operations. Any delay in our suppliers' deliveries may adversely affect our operations at multiple manufacturing locations, forcing us to seek alternative supply sources to avoid serious disruptions. Delays may be caused by factors affecting our suppliers (including the COVID-19 pandemic, capacity constraints, port congestion, labor disputes, economic downturns, availability of credit or impaired financial condition), suppliers' allocations to other purchasers, weather emergencies, natural disasters, acts of government or acts of war or terrorism. In particular, if the COVID-19 pandemic continues and results in extended periods of travel, commercial and other restrictions, we could continue to incur global supply disruptions. Any extended delay in receiving critical supplies could impair our ability to deliver products to our customers and have a material adverse effect on our results of operations, financial condition and cash flows.

A sustained market slowdown due to the impacts from the COVID-19 pandemic, other public health crises, epidemics or pandemics or otherwise, could have a material and adverse effect on our results of operations, financial condition and cash flows.

The COVID-19 pandemic triggered a significant downturn in our markets globally and these challenging market conditions could continue for an extended period of time. Most global economies slowed and there is still much uncertainty as to when these global markets will fully recover. If any or all of these major markets were to endure a sustained slowdown or recession due to the impacts of the COVID-19 pandemic, other public health crises, epidemics or pandemics or otherwise decline, it could have a material adverse effect on our results of operations, financial condition and cash flows.

Our manufacturing and supply chain abilities may be materially and adversely impacted by an extended shutdown or disruption of our operations due to the COVID-19 pandemic which could materially and adversely affect our results of operations, financial condition and cash flows.

The outbreak of COVID-19 spread throughout the world and became a global pandemic with the resultant economic impacts evolving into a worldwide recession. The pandemic triggered a significant downturn in our markets globally, which continued to unfavorably impact market conditions throughout 2020 and these challenging market conditions could continue for an extended period of time. In an effort to contain the spread of COVID-19, maintain the well-being of our employees and stakeholders, match the reduced demand from our customers and in accordance with governmental requirements, we closed or partially shut down certain office, manufacturing, distribution and technical center facilities around the world in March 2020. Although most of our manufacturing, distribution and technical center facilities re-opened early in the second quarter of 2020, some operated at reduced capacities, most of our global office buildings remained closed through the remainder of 2020. Despite many of our markets recovering in the second half of 2020, the ongoing spread of the virus prior to widespread vaccination presents several risks to our business, especially in the first half of 2021. While the impacts of the pandemic and the resulting global recession are expected to be temporary, the duration of the production and supply chain disruptions, and related financial impacts, cannot be estimated at this time. Should the reduced manufacturing and distribution capacities continue for an extended period of time or worsen, the impact on our production and supply chain could have a material adverse effect on our results of operations, financial condition and cash flows.

We face the challenge of accurately aligning our capacity with our demand.

Our markets are cyclical in nature and we face periods when demand fluctuates significantly higher or lower than our normal operating levels, including COVID-19 related shut-downs. Accurately forecasting our expected volumes and appropriately adjusting

19

our capacity are important factors in determining our results of operations and cash flows. We manage our capacity by adjusting our manufacturing workforce, capital expenditures and purchases from suppliers. In periods of weak demand we may face under-utilized capacity and un-recovered overhead costs, while in periods of strong demand we may experience unplanned costs and could fail to meet customer demand. We cannot guarantee that we will be able to adequately adjust our manufacturing capacity in response to significant changes in customer demand, which could harm our business. In addition, the COVID-19 pandemic and related reductions in demand forced certain of our customer’s facilities around the world to close or partially shut down operations, inhibiting our ability to forecast demand and caused related closures and partial shut-downs of certain of our manufacturing facilities. If we do not accurately align our manufacturing capabilities with demand it could have a material adverse effect on our results of operations, financial condition and cash flows.

Our truck manufacturers and OEM customers discontinuing outsourcing their engine supply needs, financial distress, particularly related to the COVID-19 pandemic or bankruptcy, or a change-in-control of one of our large truck OEM customers could have a material adverse impact on our results of operations, financial condition and cash flows.

We recognize significant sales of engines and components to a few large on-highway truck OEM customers which have been an integral part of our positive business results for several years. Many are truck manufacturers or OEMs that manufacture engines for some of their own vehicles. Despite their own engine manufacturing abilities, these customers have historically chosen to outsource certain types of engine production to us due to the quality of our engine products, our emission compliance capabilities, our systems integration, their customers' preferences, their desire for cost reductions, their desire for eliminating production risks and their desire to maintain company focus. However, there can be no assurance that these customers will continue to outsource, or outsource as much of, their engine production in the future. In addition, increased levels of OEM vertical integration could result from a number of factors, such as shifts in our customers' business strategies, acquisition by a customer of another engine manufacturer, the inability of third-party suppliers to meet product specifications and the emergence of low-cost production opportunities in foreign countries. Any significant reduction in the level of engine production outsourcing from our truck manufacturer or OEM customers, financial distress of one of our large truck OEM customers due to the COVID-19 pandemic or bankruptcy or a change-in-control, could likely lead to significant reductions in our sales volumes, commercial disputes, receivable collection issues, and other negative consequences that could have a material adverse impact on our results of operations, financial condition and cash flows.

A slowdown in infrastructure development and/or depressed commodity prices could adversely affect our business.

Infrastructure development and strong commodity prices have been significant drivers of our historical growth, but as the pace of investment in infrastructure slowed in recent years (especially in China and Brazil), commodity prices were significantly lower and demand for our products in off-highway markets was weak. Weakness in commodity prices, including any negative impacts on commodity prices such as oil, gas and coal, adversely impacted mining industry participants’ demand for vehicles and equipment that contain our engines and other products over the past several years. Continued deterioration in infrastructure and commodities markets, including the impacts from COVID-19, could adversely affect our customers’ demand for vehicles and equipment and, as a result, could adversely affect our business.

We may fail to realize all of the expected enhanced revenue, earnings and cash flow from our investment in the Eaton Cummins Automated Transmission Technologies joint venture.

A significant component of our investment in the Eaton Cummins Automated Transmission Technologies joint venture related to the expected growth in automated transmission products in North America and China. While we believe we will ultimately achieve these objectives, it is possible that we will be unable to achieve our original expectations within our anticipated time frame or in the anticipated amounts. As part of the purchase accounting associated with the formation of the joint venture, significant goodwill and intangible asset balances were recorded on the consolidated balance sheet. If cash flows from the joint venture fall short of our anticipated amounts, these assets could be subject to non-cash impairment charges, negatively impacting our earnings.

We derive significant earnings from investees that we do not directly control, with more than 50 percent of these earnings from our China-based investees.

For 2020, we recognized $452 million of equity, royalty and interest income from investees, compared to $330 million in 2019. Approximately half of our equity, royalty and interest income from investees is from four of our 50 percent owned joint ventures in China - Beijing Foton Cummins Engine Co., Ltd., Dongfeng Cummins Engine Company, Ltd., Chongqing Cummins Engine Company, Ltd. and Dongfeng Cummins Emission Solutions Co. Ltd. Although a significant percentage of our net income is derived from these unconsolidated entities, we do not unilaterally control their management or their operations, which puts a substantial portion of our net income at risk from the actions or inactions of these entities. A significant reduction in the level of contribution by these entities to our net income would likely have a material adverse effect on our results of operations and cash flows.

PRODUCTS AND TECHNOLOGY

Our products are subject to recall for performance or safety-related issues.

Our products are subject to recall for performance or safety-related issues. Product recalls subject us to reputational risk, loss of current and future customers, reduced revenue and product recall costs. Product recall costs are incurred when we decide, either voluntarily or involuntarily, to recall a product through a formal campaign to solicit the return of specific products due to known or suspected performance or safety issues. Any significant product recalls could have material adverse effects on our results of operations, financial condition and cash flows. See Note 12, "PRODUCT WARRANTY LIABILITY" to the Consolidated Financial Statements for additional information.

The development of new technologies may materially reduce the demand for our current products and services.

We are investing in new products and technologies, including electrified powertrains, hydrogen production and fuel cells, for planned introduction into certain new and existing markets. Given the early stages of development of some of these new products and technologies, there can be no guarantee of the future market acceptance and investment returns with respect to our planned products, which will face competition from an array of other technologies and manufacturers. The increased adoption of electrified powertrains in some market segments could result in lower demand for current diesel or natural gas engines and components and, over time, reduce the demand for related parts and service revenues from diesel or natural gas powertrains. Furthermore, it is possible that we may not be successful in developing segment-leading electrified or alternate fuel powertrains and some of our existing customers could choose to develop their own, or source from other manufacturers, and any of these factors could have a material adverse impact on our results of operations, financial condition and cash flows.

Lower-than-anticipated market acceptance of our new or existing products or services could have a material adverse impact on our results of operations, financial condition and cash flows.

Although we conduct market research before launching new or refreshed engines and introducing new services, many factors both within and outside our control affect the success of new or existing products and services in the marketplace. Offering engines and services that customers desire and value can mitigate the risks of increasing competition and declining demand, but products and services that are perceived to be less than desirable (whether in terms of price, quality, overall value, fuel efficiency or other attributes) can exacerbate these risks. With increased consumer interconnectedness through the internet, social media and other media, mere allegations relating to poor quality, safety, fuel efficiency, corporate responsibility or other key attributes can negatively impact our reputation or market acceptance of our products or services, even if such allegations prove to be inaccurate or unfounded.

Our products are exposed to variability in material and commodity costs.

Our businesses establish prices with our customers in accordance with contractual time frames; however, the timing of material and commodity market price increases may prevent us from passing these additional costs on to our customers through timely pricing actions. Additionally, higher material and commodity costs around the world may offset our efforts to reduce our cost structure. While we customarily enter into financial transactions and contractual pricing adjustment provisions with our customers that attempt to address some of these risks (notably with respect to copper, platinum and palladium), there can be no assurance that commodity price fluctuations will not adversely affect our results of operations and cash flows. In addition, while the use of commodity price hedging instruments and contractual pricing adjustments may provide us with some protection from adverse fluctuations in commodity prices, by utilizing these instruments, we potentially forego the benefits that might result from favorable fluctuations in price. As a result, higher material and commodity costs, as well as hedging these commodity costs during periods of decreasing prices, could result in declining margins.

Our business is exposed to potential product liability claims.

We face an inherent business risk of exposure to product liability claims in the event that our products' failure to perform to specification results, or is alleged to result, in property damage, bodily injury and/or death. At any given time, we are subject to various and multiple product liability claims, any one of which, if decided adversely to us, may have a material adverse effect on our reported results of operation in the period in which our liability with respect to any such claim is recognized. While we maintain insurance coverage with respect to certain product liability claims, we may not be able to obtain such insurance on acceptable terms in the future, if at all, and any such insurance may not provide adequate coverage against product liability claims. In addition, product liability claims can be expensive to defend and can divert the attention of management and other personnel for significant periods of time, regardless of the ultimate outcome. Furthermore, even if we are successful in defending against a claim relating to our products, claims of this nature could cause our customers to lose confidence in our products and us.

GENERAL

The COVID-19 pandemic created disruptions and turmoil in global credit and financial markets and ongoing impacts could have a material adverse effect on our results of operations, financial condition and cash flows.

The COVID-19 pandemic created disruptions and turmoil in the global credit and financial markets and made it more difficult and costly for us to access capital on favorable terms to meet our liquidity needs. The disruptions to the global credit and financial markets could also have material negative impacts on business operations and financial positions of our customers and suppliers, which may negatively impact our orders, sales and supply chain. If the impacts of the COVID-19 pandemic on global credit and financial markets continue, or worsen, it could negatively impact our business, along with the financial condition of our customers and suppliers, and it could have a material adverse impact on our results of operations, financial condition and cash flows.

We may be adversely impacted by work stoppages and other labor matters.

At December 31, 2020, we employed approximately 57,825 persons worldwide. Approximately 20,279 of our employees worldwide were represented by various unions under collective bargaining agreements that expire between 2021 and 2025. While we have no reason to believe that we will be materially impacted by work stoppages or other labor matters, there can be no assurance that future issues with our labor unions will be resolved favorably or that we will not encounter future strikes, work stoppages, or other types of conflicts with labor unions or our employees. Any of these consequences may have an adverse effect on us or may limit our flexibility in dealing with our workforce. In addition, many of our customers and suppliers have unionized work forces. Work stoppages or slowdowns experienced by us, our customers or suppliers, including any work stoppages or slowdowns related to the COVID-19 pandemic, could result in slowdowns or closures that would have a material adverse effect on our results of operations, financial condition and cash flow.

We rely on our executive leadership team and other key personnel as a critical part of our human capital resources.

We depend on the skills, institutional knowledge, working relationships, and continued services and contributions of key personnel, including our executive leadership team as a critical part of our human capital resources. In addition, our ability to achieve our operating and strategic goals depends on our ability to identify, hire, train and retain qualified individuals. We compete with other companies both within and outside of our industry for talented personnel and we may lose key personnel or fail to attract, train and retain other talented personnel. Any such loss or failure could have material adverse effects on our results of operations, financial condition and cash flows.

In particular, our continued success will depend in part on our ability to retain the talents and dedication of key employees. If key employees terminate their employment or become ill as a result of the COVID-19 pandemic or otherwise, our business activities may be adversely affected and our management team’s attention may be diverted. In addition, we may not be able to locate suitable replacements for any key employees who leave.

We may be adversely impacted by the effects of climate change and may incur increased costs and experience other impacts due to new or more stringent greenhouse gas regulations designed to address climate change.

The scientific consensus indicates that emissions of greenhouse gases (GHG) continue to alter the composition of Earth’s atmosphere in ways that are affecting, and are expected to continue to affect, the global climate. The potential impacts of climate change on our customers, product offerings, operations, facilities and suppliers are accelerating and uncertain, as they will be particular to local and customer-specific circumstances. These potential impacts may include, among other items, physical long-term changes in freshwater availability and the frequency and severity of weather events as well as customer product changes either through preference or regulation.

Concerns regarding climate change may lead to additional international, national, regional and local legislative and regulatory responses. Various stakeholders, including legislators and regulators, shareholders and non-governmental organizations, are continuing to look for ways to reduce GHG emissions. We could face risks to our brand reputation, investor confidence and market share due to an inability to innovate and develop new products that decrease GHG emissions. Increased input costs, such as fuel and electricity, and compliance-related costs could also impact customer operations and demand for our products. As the impact of any future GHG legislative or regulatory requirements on our global businesses and products is dependent on the timing, scope and design of the mandates or standards, we are currently unable to predict its potential impact which could have a material adverse effect on our results of operations, financial condition and cash flows. The regulation of GHG emissions could also increase our operating costs through higher utility, transportation and materials costs.

22

Our plan to reposition our portfolio of product offerings through exploration of strategic acquisitions and divestitures may expose us to additional costs and risks.

Part of our strategic plan is to improve our revenue growth, gross margins and earnings by exploring the repositioning of our portfolio of product line offerings through the pursuit of potential strategic acquisitions and/or divestitures to provide future strategic, financial and operational benefits and improve shareholder value. There can be no assurance that we will be able to identify suitable candidates or consummate these transactions on favorable terms. The successful identification and completion of any strategic transaction depends on a number of factors that are not entirely within our control, including the availability of suitable candidates and our ability to negotiate terms acceptable to all parties involved, conclude satisfactory agreements and obtain all necessary regulatory approvals. Accordingly, we may not be able to successfully negotiate and complete specific transactions. The exploration, negotiation and consummation of strategic transactions may involve significant expenditures by us, which may adversely affect our results of operations at the time such expenses are incurred, and may divert management’s attention from our existing business. Strategic transactions also may have adverse effects on our existing business relationships with suppliers and customers.

If required, the financing for strategic acquisitions could result in an increase in our indebtedness, dilute the interests of our shareholders or both. Any acquisition may not be accretive to us for a significant period of time following the completion of such acquisition. Also, our ability to effectively integrate any potential acquisition into our existing business and culture may not be successful, which could jeopardize future financial and operational performance for the combined businesses. In addition, if an acquisition results in any additional goodwill or increase in other intangible assets on our balance sheet and subsequently becomes impaired, we would be required to record a non-cash impairment charge, which could result in a material adverse effect on our financial condition.

Similarly, any strategic divestiture of a product line or business may reduce our revenue and earnings, reduce the diversity of our business, result in substantial costs and expenses and cause disruption to our employees, customers, vendors and communities in which we operate.

Our information technology systems and our products are exposed to potential security breaches or other disruptions which may adversely impact our competitive position, reputation, results of operations, financial condition and cash flows.

We rely on the capacity, reliability and security of our information technology systems and data security infrastructure in connection with various aspects of our business activities. We also rely on our ability to expand and continually update these systems and related infrastructure in response to the changing needs of our business. As we implement new systems, they may not perform as expected. We face the challenge of supporting our older systems and implementing necessary upgrades. In addition, some of these systems are managed by third-party service providers and are not under our direct control. If we experience a problem with an important information technology system, including during system upgrades and/or new system implementations, the resulting disruptions could have an adverse effect on our business and reputation. As customers adopt and rely on cloud-based digital technologies and services we offer, any disruption of the confidentiality, integrity or availability of those services could have an adverse effect on our business and reputation.

The data handled by our information technology systems is vulnerable to security threats. Our operations routinely involve receiving, storing, processing and transmitting sensitive information pertaining to our business, customers, dealers, suppliers, employees and other sensitive matters. While we continually work to safeguard our systems and mitigate potential risks, there is no assurance that these actions will be sufficient to prevent information technology security threats, such as security breaches, computer malware, computer viruses and other "cyber attacks," which are increasing in both frequency and sophistication, along with power outages or hardware failures. These threats could result in unauthorized public disclosures of information, create financial liability, subject us to legal or regulatory sanctions, disrupt our ability to conduct our business, result in the loss of intellectual property or damage our reputation with customers, dealers, suppliers and other stakeholders. As a result of the COVID-19 pandemic and resulting government actions to restrict movement, a large percentage of our salaried employees are working remotely. This remote working environment may pose a heightened risk for security breaches or other disruptions of our information technology systems.

In addition, our products, including our engines, contain interconnected and increasingly complex systems that control various processes and these systems are potentially subject to "cyber attacks" and disruption. The impact of a significant information technology event on either of our information technology systems or our products could have a material adverse effect on our competitive position, reputation, results of operations, financial condition and cash flows.

We are exposed to political, economic and other risks that arise from operating a multinational business.

Our business is subject to the political, economic and other risks that are inherent in operating in numerous countries. These risks include:

•public health crises, including the spread of a contagious disease, such as COVID-19, and other catastrophic events;

23

•the difficulty of enforcing agreements and collecting receivables through foreign legal systems;

•trade protection measures and import or export licensing requirements;

•the imposition of taxes on foreign income and tax rates in certain foreign countries that exceed those in the U.S.;

•the imposition of tariffs, exchange controls or other restrictions;

•difficulty in staffing and managing widespread operations and the application of foreign labor regulations;

•required compliance with a variety of foreign laws and regulations; and

•changes in general economic and political conditions in countries where we operate, particularly in emerging markets.

As we continue to operate our business globally, our success will depend, in part, on our ability to anticipate and effectively manage these and other related risks. There can be no assurance that the consequences of these and other factors relating to our multinational operations will not have a material adverse effect upon us.

We face significant competition in the regions we serve.

The markets in which we operate are highly competitive. We compete worldwide with a number of other manufacturers and distributors that produce and sell similar products. We primarily compete with diesel engines and related diesel products; however, new technologies continue to be developed for gasoline, natural gas, electrification and other technologies and we will continue to face new competition from these expanding technologies. Our products primarily compete on the basis of performance, price, total cost of ownership, fuel economy, emissions compliance, speed of delivery, quality and customer support. We also face competitors in some emerging regions who have established local practices and long standing relationships with participants in these markets. There can be no assurance that our products will be able to compete successfully with the products of other companies and in other markets.

Increasing global competition among our customers may affect our existing customer relationships and restrict our ability to benefit from some of our customers' growth.

As our customers in emerging markets continue to grow in size and scope, they are increasingly seeking to export their products to other countries. This has meant greater demand for our advanced engine technologies to help these customers meet the more stringent emissions requirements of developed markets, as well as greater demand for access to our distribution systems for purposes of equipment servicing. As these emerging market customers enter into, and begin to compete in more developed markets, they may increasingly begin to compete with our existing customers in these markets. Our further aid to emerging market customers could adversely affect our relationships with developed market customers. In addition, to the extent the competition does not correspond to overall growth in demand, we may see little or no benefit from this type of expansion by our emerging market customers.

We are subject to foreign currency exchange rate and other related risks.

We conduct operations in many areas of the world involving transactions denominated in a variety of currencies. We are subject to foreign currency exchange rate risk to the extent that our costs are denominated in currencies other than those in which we earn revenues. In addition, since our financial statements are denominated in U.S. dollars, changes in foreign currency exchange rates between the U.S. dollar and other currencies have had, and will continue to have, an impact on our results of operations, financial condition and cash flows. The U.S. dollar strengthened in recent years resulting in material unfavorable impacts on our revenues in those years. If the U.S. dollar continues strengthening against other currencies, we will experience additional volatility in our financial statements.

While we customarily enter into financial transactions that attempt to address these risks and many of our supply agreements with customers include foreign currency exchange rate adjustment provisions, there can be no assurance that foreign currency exchange rate fluctuations will not adversely affect our future results of operations and cash flows. In addition, while the use of currency hedging instruments may provide us with some protection from adverse fluctuations in foreign currency exchange rates, by utilizing these instruments we potentially forego the benefits that might result from favorable fluctuations in foreign currency exchange rates.

We also face risks arising from the imposition of foreign exchange controls and currency devaluations. Foreign exchange controls may limit our ability to convert foreign currencies into U.S. dollars or to remit dividends and other payments by our foreign subsidiaries or businesses located in or conducted within a country imposing controls. Currency devaluations result in a diminished value of funds denominated in the currency of the country instituting the devaluation. See Management's Discussion and Analysis for additional information.

24

Significant declines in future financial and stock market conditions, particularly those related to the global recession due to the COVID-19 pandemic, could diminish our pension plan asset performance and adversely impact our results of operations, financial condition and cash flow.

We sponsor both funded and unfunded domestic and foreign defined benefit pension and other retirement plans. Our pension cost and the required contributions to our pension plans are directly affected by the value of plan assets, the projected and actual rates of return on plan assets and the actuarial assumptions we use to measure our defined benefit pension plan obligations, including the discount rate at which future projected and accumulated pension obligations are discounted to a present value. We could experience increased pension cost due to a combination of factors, including the decreased investment performance of pension plan assets, decreases in the discount rate and changes in our assumptions relating to the expected return on plan assets.

Significant declines in current and future financial and stock market conditions related to the COVID-19 pandemic could cause material losses in our pension plan assets, which could result in increased pension cost in future years and adversely impact our results of operations, financial condition and cash flow. Depending upon the severity and length of market declines and government regulatory changes, we may be legally obligated to make pension payments in the U.S. and perhaps other countries and these contributions could be material.

We are exposed to risks arising from the price and availability of energy.

The level of demand for our products and services is influenced in multiple ways by the price and availability of energy. High energy costs generally drive greater demand for better fuel economy in almost all countries in which we operate. Some of our engine products have been developed with a primary purpose of offering fuel economy improvements, and if energy costs decrease or increase less than expected, demand for these products may likewise decrease. The relative unavailability of electricity in some emerging market countries also influences demand for our electricity generating products, such as our diesel generators. If these countries add energy capacity by expanding their power grids at a rate equal to or faster than the growth in demand for energy, the demand for our generating products could also decrease or increase less than would otherwise be the case.

(1) Shares purchased represent shares under the Board authorized share repurchase program.
(2) Shares repurchased under our Key Employee Stock Investment Plan only occur in the event of a participant default, which cannot be predicted, and were excluded from this column.

In December 2019, the Board authorized the acquisition of up to $2.0 billion of additional common stock upon completion of the 2018 repurchase plan. In October 2018, the Board authorized the acquisition of up to $2.0 billion of additional common stock. During the three months ended December 31, 2020, we repurchased $85 million of common stock under the 2018 authorization, completing this program, and repurchased $6 million of common stock under the 2019 authorization. The dollar value remaining available for future purchases under the 2019 program at December 31, 2020, was $1,994 million.

Our Key Employee Stock Investment Plan allows certain employees, other than officers, to purchase shares of common stock on an installment basis up to an established credit limit. We hold participants’ shares as security for the loans and would, in effect, repurchase shares only if the participant defaulted in repayment of the loan. Shares associated with participants' sales are sold as open-market transactions via a third-party broker as of May 1, 2020.

EXECUTIVE SUMMARY AND FINANCIAL HIGHLIGHTS

Overview

We are a global power leader that designs, manufactures, distributes and services diesel, natural gas, electric and hybrid powertrains and powertrain-related components including filtration, aftertreatment, turbochargers, fuel systems, controls systems, air handling systems, automated transmissions, electric power generation systems, batteries, electrified power systems, hydrogen production and fuel cell products. We sell our products to original equipment manufacturers (OEMs), distributors, dealers and other customers worldwide. We have long-standing relationships with many of the leading manufacturers in the markets we serve, including PACCAR Inc, Navistar International Corporation, Daimler Trucks North America and Stellantis N.V. (Chrysler). We serve our customers through a network of over 500 wholly-owned, joint venture and independent distributor locations and over 9,000 Cummins certified dealer locations with service to approximately 190 countries and territories.

Our reportable operating segments consist of Engine, Distribution, Components, Power Systems and New Power. This reporting structure is organized according to the products and markets each segment serves. The Engine segment produces engines (15 liters and smaller) and associated parts for sale to customers in on-highway and various off-highway markets. Our engines are used in trucks of all sizes, buses and recreational vehicles, as well as in various industrial applications, including construction, agriculture, power generation systems and other off-highway applications. The Distribution segment includes wholly-owned and partially-owned distributorships engaged in wholesaling engines, generator sets and service parts, as well as performing service and repair activities on our products and maintaining relationships with various OEMs throughout the world. The Components segment sells filtration products, aftertreatment systems, turbochargers, electronics, fuel systems and automated transmissions. The Power Systems segment is an integrated power provider, which designs, manufactures and sells engines (16 liters and larger) for industrial applications (including mining, oil and gas, marine and rail), standby and prime power generator sets, alternators and other power components. The New Power segment designs, manufactures, sells and supports hydrogen production solutions as well as electrified power systems ranging from fully electric to hybrid along with innovative components and subsystems, including battery and fuel cell technologies. We continue to serve all our markets as they adopt electrification and alternative power technologies, meeting the needs of our OEM partners and end customers.

30

Our financial performance depends, in large part, on varying conditions in the markets we serve, particularly the on-highway, construction and general industrial markets. Demand in these markets tends to fluctuate in response to overall economic conditions. Our sales may also be impacted by OEM inventory levels, production schedules and stoppages. Economic downturns in markets we serve generally result in reduced sales of our products and can result in price reductions in certain products and/or markets. As a worldwide business, our operations are also affected by currency, political, economic, public health crises, epidemics or pandemics and regulatory matters, including adoption and enforcement of environmental and emission standards, in the countries we serve. As part of our growth strategy, we invest in businesses in certain countries that carry high levels of these risks such as China, Brazil, India, Mexico, Russia and countries in the Middle East and Africa. At the same time, our geographic diversity and broad product and service offerings have helped limit the impact from a drop in demand in any one industry or customer or the economy of any single country on our consolidated results.

COVID-19 Update

The outbreak of COVID-19 spread throughout the world and became a global pandemic with the resultant economic impacts evolving into a worldwide recession. The pandemic triggered a significant downturn in our markets globally, which continued to unfavorably impact market conditions throughout 2020 and these challenging market conditions could continue for an extended period of time. In an effort to contain the spread of COVID-19, maintain the well-being of our employees and stakeholders, match the reduced demand from our customers and in accordance with governmental requirements, we closed or partially shut down certain office, manufacturing, distribution and technical center facilities around the world in March 2020. Although most of our manufacturing, distribution and technical center facilities re-opened early in the second quarter of 2020, some operated at reduced capacities, most of our global office buildings remained closed through the remainder of 2020. Despite many of our markets recovering in the second half of 2020, the ongoing spread of the virus prior to widespread vaccination presents several risks to our business, especially in the first half of 2021.

COVID-19 vaccines are currently being administered around the world with the hope that the majority of the population will have access to the vaccine by the middle of 2021. If the distribution and the effectiveness of the vaccine are consistent with current government and health organization estimates, we anticipate the vaccine will mitigate the spread of the virus by the end of 2021 and allow a return to more normal operations in the second half of the year.

While the impacts of the pandemic and the resulting global recession are expected to be temporary, the duration of the production and supply chain disruptions, and related financial impacts, cannot be estimated at this time. Should the reduced manufacturing and distribution capacities continue for an extended period of time or worsen, the impact on our production and supply chain could have a material adverse effect on our results of operations, financial condition and cash flows. Our Board of Directors (the Board) continues to monitor and evaluate all of these factors along with the continuing impacts of the COVID-19 pandemic on our business and operations.

2020 Results

A summary of our results is as follows:

	Years ended December 31,
In millions, except per share amounts	2020		2019		2018
Net sales	$	19,811	$	23,571	$	23,771
Net income attributable to Cummins Inc.	1,789		2,260		2,141
Earnings per common share attributable to Cummins Inc.
Basic	$	12.07	$	14.54	$	13.20
Diluted	12.01		14.48		13.15

Worldwide revenues decreased 16 percent in 2020 compared to 2019, as we experienced lower demand in all major operating segments and most geographic regions due to the economic impacts of COVID-19 and the anticipated 2020 down cycle in most of our markets. Net sales in the U.S. and Canada declined by 21 percent primarily due to COVID-19 impacts resulting in decreased demand in the North American on-highway markets, which also negatively impacted our emission solutions, automated transmissions and turbo technologies businesses, reduced sales in all distribution product lines, decreased demand for power generation equipment and lower demand in off-highway markets (especially construction). International demand (excludes the U.S. and Canada) declined by 7 percent compared to 2019, with lower sales in all geographic regions except China. The decrease in international sales was principally due to COVID-19 impacts resulting in lower demand for industrial products (primarily international mining markets), decreased demand for power generation equipment, lower volumes in on-highway markets (mainly medium-duty truck markets), reduced demand in all distribution product lines and unfavorable foreign currency impacts of 2 percent of international sales (primarily the

31

Brazilian real and Indian rupee), partially offset by higher demand in our emission solutions business in China and India and our electronics and fuel systems business in China.

The following table contains sales and EBITDA (defined as earnings or losses before interest expense, income taxes, depreciation and amortization and noncontrolling interests) by operating segment for the years ended December 31, 2020 and 2019. See Note 22, "OPERATING SEGMENTS," to the Consolidated Financial Statements for additional information and a reconciliation of our segment information to the corresponding amounts in our Consolidated Statements of Net Income.

	Operating Segments

Net income attributable to Cummins Inc. for 2020 was $1.8 billion, or $12.01 per diluted share, on sales of $19.8 billion, compared to 2019 net income attributable to Cummins Inc. of $2.3 billion, or $14.48 per diluted share, on sales of $23.6 billion. The decrease in net income attributable to Cummins Inc. and earnings per diluted share was driven by lower net sales, decreased gross margin, a higher effective tax rate and unfavorable foreign currency fluctuations (primarily the Brazilian real), partially offset by prior restructuring actions, temporary salary reductions and reduced variable compensation resulting in lower overall compensation expenses, increased equity, royalty and interest income from investees primarily in China (due to stronger demand for construction equipment and trucks) and favorable adjustments related to India Tax Law Changes in March 2020. The decrease in gross margin and gross margin percentage was mainly due to lower volumes, partially offset by prior restructuring actions, temporary salary reductions and lower variable compensation resulting in decreased compensation expenses and lower material costs. Diluted earnings per common share for 2020 benefited $0.24 per share from fewer weighted-average shares outstanding, primarily due to the stock repurchase program.

We generated $2.7 billion of operating cash flows in 2020, compared to $3.2 billion in 2019. See the section titled "Cash Flows" in the "LIQUIDITY AND CAPITAL RESOURCES" section for a discussion of items impacting cash flows.

Our debt to capital ratio (total capital defined as debt plus equity) at December 31, 2020, was 31.7 percent, compared to 21.9 percent at December 31, 2019. The increase was primarily due to a $1,797 million higher total debt balance as the result of our August 2020 debt issuance. At December 31, 2020, we had $3.9 billion in cash and marketable securities on hand and access to our $3.5 billion credit facilities, if necessary, to meet currently anticipated working capital, investment and funding needs.

In the first half of 2020, we entered into additional interest rate lock agreements to reduce the variability of the cash flows of the interest payments on a total of $500 million of fixed rate debt forecast to be issued in 2023 to replace our senior notes at maturity.

In 2020, we repurchased $641 million or 3.9 million shares of common stock. See Note 15, "CUMMINS INC. SHAREHOLDERS' EQUITY" to the Consolidated Financial Statements for additional information.

In June and July of 2020, we settled our February 2014 interest rate swaps, which previously converted our $500 million debt issue, due in 2023, from fixed rate to floating rate based on a LIBOR spread. We will amortize the $24 million gain realized upon settlement over the remaining three-year term of the related debt.

On August 19, 2020, we entered into an amended and restated 364-day credit agreement that allows us to borrow up to $1.5 billion of unsecured funds at any time prior to August 18, 2021. This credit agreement amended and restated the prior $1.5 billion-day credit facility that matured on August 19, 2020.

On August 24, 2020, we issued $2 billion aggregate principal amount of senior unsecured notes consisting of $500 million aggregate principal amount of 0.75% senior unsecured notes due in 2025, $850 million aggregate principal amount of 1.50% senior unsecured notes due in 2030 and $650 million aggregate principal amount of 2.60% senior unsecured notes due in 2050. We received net proceeds of $1.98 billion.

32

In October 2020, the Board authorized an increase to our quarterly dividend of 3 percent from $1.311 per share to $1.35 per share.

In 2020, the investment gain on our U.S. pension trust was 8.9 percent while our U.K. pension trust gain was 13.7 percent. Our global pension plans, including our unfunded and non-qualified plans, were 112 percent funded at December 31, 2020. Our U.S. defined benefit plan, which represents approximately 52 percent of the worldwide pension obligation, was 128 percent funded, and our U.K. defined benefit plan was 114 percent funded. We expect to contribute approximately $75 million in cash to our global pension plans in 2021. In addition, we expect our 2021 net periodic pension cost to approximate $78 million. See application of critical accounting estimates within MD&A and Note 13, "PENSIONS AND OTHER POSTRETIREMENT BENEFITS," to the Consolidated Financial Statements, for additional information concerning our pension and other postretirement benefit plans.

On April 29, 2019, we announced that we were conducting a formal internal review of our emissions certification process and compliance with emission standards for our pick-up truck applications, following conversations with the U.S. Environmental Protection Agency and California Air Resources Board regarding certification of our engines in model year 2019 RAM 2500 and 3500 trucks. We voluntarily disclosed our formal internal review to the regulators and to other government agencies, the Department of Justice (DOJ) and the SEC. We fully cooperated with the DOJ’s and the SEC’s information requests and inquiries and, based on recent communications with these agencies, we do not expect further inquiries. Due to the continuing nature of our formal review, our ongoing cooperation with our regulators and the presence of many unknown facts and circumstances, we cannot predict the final outcome of this review and these regulatory processes, and we cannot provide assurance that the matter will not have a materially adverse impact on our results of operations and cash flows. See Note 14, "COMMITMENTS AND CONTINGENCIES," to the Consolidated Financial Statements for additional information.

As of the date of this filing, our credit ratings and outlooks from the credit rating agencies remain unchanged.
