2021 SUSTAINABILITY PROGRESS REPORT | Cummins Inc. 2 CUMMINS AND 2021: A YEAR OF ACTION 2021 was dominated by challenges demanding action, from Cummins and our stakeholders. It will take all of us working together to address these broad and systemic issues, and Cummins is committed to taking a leadership role in these efforts. LEADING THE TRANSITION TO ZERO EMISSIONS Climate change is the existential crisis of our time. Climate-related catastrophes present a growing threat to the communities where we do business and to our plants, facilities, supply chain and customers around the world. Climate change is also the greatest threat to achieving our mission of making people’s lives better by powering a more prosperous world. The decarbonization of our economy is critical to our way of life, and our industry will play a key role in it. Our journey to zero emissions is also a growth opportunity for Cummins. We are confident in our ability to lead in bringing lower carbon technologies to commercial and industrial markets globally due to the unique capabilities Cummins has built over many years. Our company’s strategy to lead in this work is aligned with our sustainability goals, and we have a history of being a leader in sustainability. Over the last 20 years, we have reduced NOx (nitrogen oxides) and particulate matter emissions from today’s engines by over 90%. This new chapter of innovating for low carbon technology is another opportunity for us to deliver on our mission and provide solutions to our customers. Chairman and CEO Tom Linebarger announces to the Spanish media and invited guests that Cummins will build in Spain one of the largest manufacturing plants for electrolyzers in the world.

2021 SUSTAINABILITY PROGRESS REPORT | Cummins Inc. 3 We used our lessons learned during the pandemic to create enhanced ways of working for Cummins employees. We are steadfast in our commitment to building a dynamic workplace where all employees are inspired and encouraged to achieve their full potential. We recognize that how we work in the future will be different from how we have worked in the past. Through enhanced ways of working that are more flexible, agile and inclusive, we can increase the productivity of our teams and create a better environment for our employees. LEADING TO SERVE OUR STAKEHOLDERS Our long-standing commitment to our stakeholders—our communities, customers, employees, partners and shareholders— remains a top priority. Aligned with our stakeholder model, we believe that each stakeholder in a company is served best by supporting every stakeholder. At Cummins, we do this by living our core values inside and outside of the workplace. Our success depends on our ability to create a diverse, equitable and inclusive culture. Diversity, equity and inclusion (DE&I) is a Only Cummins can power our customers’ success through this transition with our growing portfolio of diesel, natural gas, propane, hydrogen, fuel cell and battery system solutions. LEADING TO CREATE A GREAT WORK ENVIRONMENT Despite our desire for the pandemic to end, COVID-19 continued to rage on. In 2021, we focused on encouraging our employees to get COVID-19 vaccinations to keep everyone as safe and healthy as possible. We started by launching a global employee survey on vaccine interest, questions and concerns. We used those responses to launch a global vaccine education campaign where employees could get answers on vaccine topics from knowledgeable sources they trust. As vaccines became available, we delivered more than 45,000 vaccine shots around the world to protect Cummins employees, contractors and their families, sponsoring vaccination clinics from India to Indiana. In the U.S., we also launched a vaccine incentive program. » A global strategic partnership with Daimler to provide medium-duty powertrain systems for Daimler Trucks and Buses. » An agreement with Iberdrola, one of the world’s largest energy companies, on large-scale hydrogen production projects in Spain and Portugal. » A Letter of Intent to acquire 50% equity interest in Momentum Fuel Technologies from Rush Enterprises to produce Cummins- branded natural gas fuel delivery systems for the commercial vehicle market in North America. » An agreement with Sion Power Corporation to design and supply battery cells based on their proprietary lithium metal technology for commercial vehicle applications; and » The formation of a 50:50 joint venture with Sinopec to form Cummins Enze, which will accelerate the affordability and availability of green hydrogen in China. In 2021, we took several steps to address climate change in critical parts of the economy:  We announced a new 15-liter engine platform for heavy duty trucks that will begin with a natural gas version and later be available in a variety of fuels from diesel to hydrogen. This platform will offer leading power and performance while meeting more stringent emissions regulations.  Cummins passed more than 2,000 fuel cells deployed and built a new fuel cell systems production facility in Herten, Germany.  We exceeded 500 buses moving communities forward with our BEV (battery electric vehicle) technology and in 2022 surpassed 1 million miles driven by Blue Bird’s Cummins-powered electric school buses since 2018.  Our company began work on what will be one of the world’s largest electrolyzer production plants in Spain.  Cummins launched several key partnerships and acquisitions, including: CEO LETTER //

Cummins employee-led volunteerism and grantmaking reached record levels last year, with $35.7 million in global community giving and more than 186,000 volunteer hours. MOVING FORWARD TOGETHER We cannot get where we need to be acting alone—whether on climate action, the pandemic or supporting our communities. Partnering with our many stakeholders has never been more important to making progress on these enormous challenges. Our children and their children will look back and ask what we did to address these issues, and we must work together to solve them. Tom Linebarger Chairman and Chief Executive Officer In just one year, our CARE program invested more than $20 million into communities, including $3.75 million in grants and forgivable loans to over 300 Black-owned businesses. CARE volunteers participated in 16 advocacy initiatives, resulting in eight law and policy changes, including revisions to two public safety use-of-force protocols. Institutional racism is a disease. It will take decisive and sustained action to dismantle racism, and Cummins will be part of that action. We continue to invest significant time and funds into our communities. With the launch of Cummins Water Works last July, Cummins now has global strategic community initiatives aligned with each of our community priority areas of Education, Equality of Opportunity and Environment. In Education, Cummins TEC: Technical Education for Communities, has 25 schools in 12 countries. For Equality of Opportunity, our $22 million commitment in Cummins Powers Women has benefitted an estimated 26 million women and girls. And finally, Cummins Water Works focuses on being part of the collective action required to solve the growing global water crisis. Supported initially by more than $8 million in Cummins source of competitive advantage. We have a history of bringing people together with different talents to solve complex problems and drive innovation. Our commitment to diversity enables us to attract the best talent, and our commitment to equity and inclusion positions us to deploy our talent more effectively than others. There are many companies working to solve complicated global challenges. Our communities also thrive when we create more equitable and inclusive environments. In 2020, we launched the Cummins Advocating for Racial Equity (CARE) initiative in the U.S. that focuses on achieving police reform, realizing criminal justice reform, creating economic empowerment by building Black wealth and income, and driving social justice reform in healthcare, housing, workforce development and civil rights, including voting rights and education.

CUMMINS 2021-22 SUSTAINABILITY OVERVIEW At Cummins, we know some people are looking for a presentation that is a little shorter than many of our sustainability and ESG reports. Once again, the company has produced a shorter overview of Cummins’ sustainability initiatives covering 2021 and the first half of 2022. You can find our newest overview in our sustainability document archive . in 2011 to provide investors with industry- specific sustainability information about the companies they are investing in. CUMMINS 2021 TASK FORCE ON CLIMATE-RELATED FINANCIAL DISCLOSURE REPORT Cummins will also be reporting to the Taskforce on Climate-related Financial Disclosures (TCFD). Created in 2017, TCFD is designed to provide investors and others with a clearer picture of a company’s climate- related disclosures and climate-related risks. CUMMINS DATA Cummins works with Apex, a leader in verification and assurance, to review key environmental, social and governance data. Apex’s assurance letter will be posted in Cummins’ sustainability document archive as soon as it is available. For environmental data, company facilities include all consolidated operations and joint ventures that are part of the Cummins Enterprise Environmental Management System. Employee data consists of just consolidated operations. Financial data comes from the CUMMINS 2022 CDP REPORT Cummins is committed to sharing its annual CDP (formerly the Carbon Disclosure Project) water and climate filings. The CDP was established to help build a truly sustainable economy by increasing understanding around a company’s environmental impact. CUMMINS 2021 GLOBAL REPORTING INITIATIVE CONTENT INDEX AND DATA BOOK The company plans to again produce a separate posting aligned to the Global Reporting Initiative (GRI) platform based on the company’s 2021 data. The GRI was established by a partnership including the United Nations to provide a consistent way for companies to report on their ESG performance. CUMMINS 2021 SUSTAINABILITY ACCOUNTING STANDARDS BOARD REPORT INDEX Cummins plans to produce a report aligned specifically to the disclosures in the Sustainability Accounting Standards Board (SASB) reporting platform, updating the report filed in 2020. SASB was established SUSTAINABILITY AT CUMMINS Cummins’ approach to sustainability aligns with the company’s mission to make people’s lives better by powering a more prosperous world. A more prosperous world has a financial component, but at Cummins it means more than that. A more prosperous world is also a world with clean air and clean water, and a world where businesses partner with other stakeholders to weave a stronger social fabric. The company has long believed success is about more than just the bottom line. The Cummins Sustainability Progress Report is divided into three sections to show the company’s progress toward its mission: environmental reporting, social reporting, and governance and economic reporting. Cummins strives to be consistent with the reporting structures established by the Global Reporting Initiative (GRI), the Sustainability Accounting Standards Board (SASB) and the Taskforce for Climate-related Financial Disclosures (TCFD).

2021 SUSTAINABILITY PROGRESS REPORT | Cummins Inc. 7 ABOUT THE COVER Cummins approached living with the pandemic in its typical workman-like fashion in 2021, advancing the company’s sustainability initiatives, overcoming uncertainties in the global supply chain, and taking a leadership role in the transition to a no-carbon economy. By early 2022, Cummins President and Chief Operating Officer Jennifer Rumsey (1) was welcoming back office employees in the company’s home state of Indiana, consistent with recommendations by the Centers for Disease Control and Prevention as COVID-19 rates fell in the U.S. Midwest. Looking back, 2021 will be remembered at Cummins as a year of innovation, determination, celebration and dedication, as the company worked to reduce its carbon footprint. Cummins, for example, constructed a record number of solar installations at company facilities around the world, including what will be Cummins’ second largest solar array at the Rocky Mount Engine Plant in North Carolina (2). Cummins celebrated recognition from Prince Charles (3), who announced in Glasgow, Scotland, the company was among the inaugural recipients of the Terra Carta Seal, emblematic of industry leadership on decarbonization. The award also reflected the dedication of essential employees across the company, who kept Cummins moving forward in the face of the pandemic. Their efforts were critical as the company worked to reduce the carbon produced by its core products and bring to market the low- and no-carbon technologies that will power the future (4,5). While the challenges are many looking ahead, 2021 showed, yet again, Cummins is up to the task. 1 2 3 4 5 ABOUT COVER //

2021 SUSTAINABILITY PROGRESS REPORT | Cummins Inc. 8 MATRIX ESTABLISHES REPORTING PRIORITIES Cummins’ materiality matrix determines the relevant topics sufficiently important for the company to report on. This report puts a special focus on the upper right quadrant of the matrix where topics are highly relevant to both Cummins and its stakeholders. A cross-functional team annually reviews the matrix to determine if topics should be added or moved, aligning it to stakeholder requests for information, the company’s risk evaluation process and other information sources. Cummins updated its matrix in 2020 to reflect critical concerns around COVID-19 and racial equity. They remain topics of importance both for the company and its stakeholders, reflected in the placement of “Organizational resiliency,” “Occupational health and safety,” and “Diversity, equity and inclusion” in the upper right quadrant. The committee also shifted “Climate action” to the upper right quadrant to reflect stakeholders’ growing concern with that global challenge as well as Cummins’ position that climate change is both a threat to the company’s mission to make people’s lives better by powering a more prosperous world, and an opportunity for company growth. The 2021 matrix also consolidates several topics under “Human capital management” to better reflect stakeholders’ increasing interest in the critical role employees play in corporate sustainability. The updated matrix also consolidates topics around “Supply chain” as companies around the world endure parts shortages and other supply chain challenges. Finally, Cummins continues to report on topics the company believes are essential to sustainability found in the upper left hand quadrant of its matrix. Climate action – product GHG emissions Product innovation Organizational resiliency Emissions compliance Occupational health and safety Cybersecurity – data and products Human capital management Diversity, equity and inclusion Facility emissions, including GHGs Sustainable water supplies Supply chain: Elasticity and human rights Financial management IP protection Ethics and compliance Product lifecycle and remanufacturing Waste reduction Material sourcing Public advocacy Supplier diversity Community engagement REPORTING TOPICS IMPORTANT TO STAKEHOLDERS REPORTING TOPICS IMPORTANT TO COMPANY FOUNDATIONAL IMPACTS TO REPORT EXTERNALLY Essential elements to overall corporate sustainability High priorities for company and stakeholders CRITICAL IMPACTS TO REPORT EXTERNALLY REPORTING MATERIALITY MATRIX This diagram captures the upper half of the company’s Reporting Materiality Matrix to enhance clarity.

      2021 SUSTAINABILITY PROGRESS REPORT | Cummins Inc. 1,631 723M Estimated financial impact in dollars of Six Sigma projects at Cummins in 2021. 5,845 Employees achieving Six Sigma belt certifications in 2021. 2.5+ BILLION Estimated savings achieved by Cummins customers from Six Sigma since the tool was first offered to them in 2005. 15 SIX SIGMA BY THE NUMBERS Equity (CARE) initiative. CARE team members have employed Six Sigma to tackle difficult social justice concerns. Over time the company added tools to its tool kit and in 2021 Cummins expanded the Six Sigma function into IQTM—Intelligent Quality Tools and Methods. The company’s IQTM function leads Cummins’ efforts to continuously improve the products and services customers depend on. EXPANDING THE MISSION These tools make Cummins a better company and help the global power leader sustain the improvements it makes to deliver on Cummins’ brand promise of powering customers through innovation and dependability. The company today offers dozens of tools employees can use to define a problem, collect relevant data, analyze the problem and ultimately find a solution. Most tools fit within the Six Sigma umbrella, but now employees have many different options, so they can choose what works best to reach their desired result. Ultimately, the IQTM function’s mission is preparing employees and the company to succeed in the digital age, adding tools and capabilities as they become available. INCREASING ACCESS In addition to expanding the tools the company offers, the IQTM team has been working over the past two years to get more tools in more hands at Cummins, providing on-line learning opportunities and moving away from classroom training, which could be something of a bottleneck as interest in courses frequently exceeded available classroom space. The IQTM team offers tools and processes specifically geared to employees’ skill levels, whether they are an experienced Six Sigma Black Belt or entirely new to the concept. The function is building on a track record of success. The company’s Six Sigma efforts have identified more than $7.5 billion in Profit Before Interest and Taxes savings since the tool was first implemented in 2000. LOOKING AHEAD As the IQTM function moves forward it wants to continue embedding “Lean” business management practices and principles across the company to eliminate waste and increase efficiency, becoming partners with each business segment to improve quality. The IQTM team also wants to help every Cummins employee gain the necessary skills to excel in manufacturing in the digital age. CUMMINS EXPANDS TOOLS FOR CONTINUOUS IMPROVEMENT Cummins is a continuous improvement company. For more than 20 years, the global power leader has used Six Sigma, the business problem solving tool, to drive that improvement, from Cummins’ supply chain to its community engagement efforts. Six Sigma’s data-based analysis is used primarily to identify defects and variation in a wide range of manufacturing and business situations. Cummins also encourages its suppliers to use the tool, and partners with customers to solve their biggest challenges using Six Sigma. In addition, Cummins uses the tool in its efforts to build stronger communities, including as part of its Cummins Advocating for Racial INTELLIGENT QUALITY TOOLS AND METHODS (IQTM) // Closed Six Sigma projects across Cummins in 2021.

      2021 SUSTAINABILITY PROGRESS REPORT | Cummins Inc. 19 ENVIRONMENTAL PROGRESS // 2030 GOAL UPDATE More than 3,000 businesses and financial institutions, including Cummins, are working with the Science Based Target initiative (SBTi) to reduce their emissions in line with climate science. Following the Paris Climate Agreement in 2015, organizations including the United Nations Global Compact, the CDP (formerly the Carbon Disclosure Project), the World Wildlife Fund and the World Resources Institute partnered to develop the SBTi to set science-based emissions reduction targets. In 2017, Cummins pledged to develop targets within the SBTi framework. In 2019, the company announced two goals aligned to the framework—one for newly sold products and the other for facilities and operations. The facilities and operations goal is specifically tied to keeping global warming to a 1.5º C temperature increase over pre-industrial levels while the newly sold products goal is aligned to a 1.5º C to 2º C range. Cummins also set seven other 2030 goals as part of PLANET 2050 , the company’s environmental sustainability strategy. This is Cummins’ first progress report on them. 1. Reduce absolute greenhouse gas (GHG) emissions from facilities and operations by 50%. 2. Reduce Scope 3 absolute lifetime GHG emissions from newly sold products by 25%. 3. Partner with customers to reduce Scope 3 GHG emissions from products in the field by 55 million metric tons. 4. Reduce emissions of volatile organic compounds from paint and coating operations by 50%. 5. Create a circular lifecycle plan for every part to use less, use better, use again. 6. Generate 25% less waste in facilities and operations as a percent of revenue. 7. Reuse or responsibly recycle 100% of packaging plastics and eliminate single-use plastics in dining facilities, at employee events and as amenities. 8. Reduce absolute water consumption in facilities and operations by 30%. 9. Produce net water benefits that exceed Cummins’ annual water use in all Cummins regions. CUMMINS’ 2050 ASPIRATIONAL TARGETS DOING OUR PART TO ADDRESS CLIMATE CHANGE AND AIR EMISSIONS 2050 TARGETS: Customer success is powered by carbon neutral technologies that address air quality.   Carbon neutrality and near zero pollution in Cummins’ facilities and operations. 2050 TARGETS: Net positive impact in every community where Cummins operates. Near zero local site environmental footprin t. COMMUNITIES ARE BETTER BECAUSE WE ARE THERE USING NATURAL RESOURCES IN THE MOST SUSTAINABLE WAY 2050 TARGETS: Design out waste in products and processes. Use materials again for next life. Reuse water and return clean to the community.

CUMMINS OFF TO GOOD START IN REACHING FACILITIES’ GHG GOAL In 2021, Cummins began to see a return to something closer to normal operations after the company’s low point for energy use in 2020, due primarily to the COVID-19 pandemic. The PLANET 2050 goal for 2030 shifted from the company’s 2020 goal based on an energy intensity measure to an absolute greenhouse gas (GHG) reduction. While business growth in 2021 in some markets increased absolute energy use, GHG emissions overall for Cummins declined. From the goal’s baseline year of 2018 to 2021, GHGs decreased by 277,000 metric tons, equivalent to a 31% reduction from the baseline. The reduction can be attributed to several factors:  Completion of India solar projects and a virtual power purchase agreement with an Indiana windfarm.  LED lighting and compressed air efficiency projects across the company.  The impact of the pandemic on energy use. Normal operations were in place at most manufacturing facilities in 2021, but some offices remained closed where employees could do their jobs working from home. In 2021, Cummins completed more than 155 projects reducing GHGs, investing approximately $20 million. As a result, the company achieved GHG savings of 22,495 metric tons of CO 2 e (carbon dioxide equivalent). Thirty percent of the GHG reductions can be attributed to solar projects in India and Australia. Several facilities made equipment upgrades to chillers, boilers, and air conditioning units. Although most large sites have converted to LED lighting, lighting still contributes to GHG reductions, representing 15% of the 2021 GHG savings. ENVIRONMENTAL PROGRESS // GOAL 1: Reduce absolute greenhouse gas emissions from facilities and operations by 50% by 2030. GREENHOUSE GAS IS GROUPED INTO THREE GROUPS OR SCOPES SCOPE 1: Includes direct emissions from the use of fuel for stationary and mobile applications, fugitive and refrigerant emissions. SCOPE 2: Includes indirect emissions from the generation of purchased electricity and steam. SCOPE 3: Includes all other indirect emissions that occur in a company’s value chain. Crews install a solar array at the company’s engine plant in Rocky Mount, North Carolina (U.S.). When complete in 2022 it will be the second largest array at a Cummins facility. NOTE: Goal calculation uses market-based Scope 2 emissions.

      2021 SUSTAINABILITY PROGRESS REPORT | Cummins Inc. PROGRESS ON GOAL TO REDUCE LIFETIME EMISSIONS This chart looks at lifetime emissions from newly sold products. LIFETIME EMISSIONS FROM NEWLY SOLD PRODUCTS (million metric tons of CO 2 e) This graphic is based on a number of estimates, assumptions and projections, ranging from product mix and volumes to the carbon intensity of fuels used as well as end customer duty cycles and real world fuel economy. Assumptions also include how customers will use company products over their lifetime. This uncertainty is illustrated by the blue bar on top of each column showing a range of potential outcomes. Cummins may revise these projections as better tools and information become available. INCLUDED: » Cummins custodial plant volumes » Consolidated and non-consolidated JV volumes EXCLUDED: » Generators powered by outsourced engines » Remanufactured products’ emissions ENVIRONMENTAL PROGRESS // 21 ABOUT CARBON MODELING Cummins is fully committed to transparency in its goal reporting and has provided its calculation assumptions for lifetime emissions through various reporting frameworks. Since the company first reported an estimate for the lifetime emissions of its products in 2015, Cummins has been able to identify and leverage increasingly sophisticated tools and data for carbon modeling. The company will continue to update its GHG accounting methods to the best available information and practices and communicate sources of known or potential uncertainty. That may result in changes to its baseline or prior years’ emissions. For example, 2018 baseline year emissions have been revised since initially set with the SBTi. In addition, Cummins intends to reassess its goal as encouraged by the SBTi within the five-year recommended timeframe. product’s estimated lifetime. The goal does not include full lifecycle or well-to-wheel considerations. Cummins used sector decarbonization data provided by the Science Based Targets initiative (SBTi) and applied it to the company’s existing lifetime emissions model. While initiatives are underway to reduce the carbon produced by Cummins’ products (see Innovation section on page 65), the company has said since announcing this goal it will require working with its stakeholders to achieve significant carbon reductions. Key enablers for reaching the goal include:  Strong regulatory support for GHG reductions.  Continued machine and powertrain efficiency improvements.  Broader availability of lower carbon fuels.  Advancements in new technology powertrains.  Market adoption of new technology powertrains.  Customer and industry partnerships to reduce carbon. Cummins is committed to taking a leadership role in the effort to reduce carbon, working with others to achieve the world’s climate goals. CUMMINS SETS STAGE TO REDUCE GHG EMISSIONS FROM NEWLY SOLD PRODUCTS Cummins has many exciting improvements planned for the company’s core products aligned to PLANET 2050 and Destination Zero, including the Unified Product Platform . The impact of these initiatives, however, is a few years away, and mass adoption of Cummins’ low- and no- carbon platforms is just beginning to build. It is perhaps not surprising, then, that lifetime greenhouse gas (GHG) emissions from newly sold products in 2021 were essentially flat compared to the goal’s baseline year of 2018. Cummins’ commitment, though, is clear as leaders say the drive to reduce carbon emissions is a growth opportunity for the company. The scope for Cummins products’ science-based target includes GHG emissions generated during the use phase throughout the GOAL 2: Reduce Scope 3 absolute lifetime GHG emissions from newly sold products by 25%. 0 820 1,162 1,094 2030 2021 2018

ENVIRONMENTAL PROGRESS // DOING OUR PART BY THE NUMBERS 9 BILLION Customer savings in dollars from products in use fuel economy projects since environmental sustainability goals were established in 2014. Projects with customers also saved 3 billion gallons of fuel and avoided 27 million metric tons of CO 2 . Since first surpassing the company’s 2020 goal in 2018, Cummins has continued partnering with customers to implement fuel savings projects and is on track to exceed its 2030 goal. In 2021, an additional 50 customer projects were completed, bringing the cumulative total since 2014 to 700. The PLANET 2050 goal is now formally expressed as a cumulative carbon dioxide (CO 2 ) reduction since a baseline year of 2014, rather than the annual run rate achieved. Cummins and its customer partnerships achieved big gains in the early years of this initiative as projects with high returns were identified and completed. As products have become more and more efficient, Cummins is now tackling increasingly complex projects to achieve fuel economy savings, including route optimization and the introduction of lower emissions fuels. Customers continue to show interest and dedication to improving their product environmental footprint, and Cummins is dedicated to continuing to partner to help customers achieve their sustainability goals. CUMMINS ON PACE TO ACHIEVE EMISSION REDUCTION GOAL PARTNERING WITH CUSTOMERS From optimizing products for specific market segments, to the use of sophisticated digital tools to assist in the truck specification process, to the ability to customize electronic engine settings and parameters, Cummins helps customers reduce their carbon footprint throughout the life of the company’s products. GOAL 3: Partner with customers to reduce Scope 3 GHG emissions by 55 million metric tons of carbon dioxide (CO 2 ).

DESTINATION ZERO AND PLANET 2050 In January of 2022, Cummins publicly unveiled Destination Zero, the company’s strategy for decarbonization. Destination Zero builds on the PLANET 2050 environmental sustainability strategy, providing a road map of sorts to achieving PLANET 2050’s aspirational target of powering customer success with net-zero emissions technology by 2050. The Destination Zero strategy calls for investing and advancing zero-emission technologies for those customers who are ready today, while providing those who aren’t, either because of economic concerns, concerns about infrastructure, or other reasons the chance to achieve critical carbon reductions using the company’s core technologies. Cummins believes making carbon reductions as quickly as possible is critical to achieve the world’s climate goals. Destination Zero is also a bottom-line strategy in that Cummins sees carbon reduction as a growth opportunity for the company. You can see how decarbonization drives innovation at Cummins in the Innovation section (page 65) of this report. More on Destination Zero is available on a public-facing website on cummins.com. ENVIRONMENTAL PROGRESS // 23 Even with the rebound of production volumes in 2021, the resulting reductions and data show that the company achieved a 45% VOC emission reduction at the end of 2021. To drive further improvements and focus on actions reducing VOCs at the source, the company launched a project in 2021 focused on sites with elevated emissions to understand the complexities and options to reduce emissions and create a roadmap supporting a global deployment plan for the future. GOAL 4: Reduce emissions of volatile organic compounds from paint and coating operations by 50%. EFFORT TO CLEAR THE AIR STARTS STRONG Addressing air pollution is a top environmental priority for Cummins products as well as the company’s facilities and operations. Volatile organic compounds (VOCs) are a key component in the formation of smog, and VOC emissions are highly regulated in many of the countries where Cummins operates. Painting and coating processes at company facilities account for 73% of the VOC emissions from Cummins facilities, with the rest from combustion of fossil fuels. Cummins has a mix of sites using solvent- and water-based paints and resins. Some sites have transitioned to water-based materials and/or installed air emission abatement systems to comply with stringent local regulations to reduce their VOC footprint.

      2021 SUSTAINABILITY PROGRESS REPORT | Cummins Inc. 24 ENVIRONMENTAL PROGRESS // Cummins in 2021 began laying the foundation for meeting its goal of a lifecycle plan for every part, achieving two important steps the company can build on moving forward. In addition to building support for the goal and establishing the employee committees to lead the effort, Cummins established a Circular Lifecycle Design Standard. Design standards serve as a roadmap for engineers as they put together part designs. The new standard includes steps like review by the Materials Science function to ensure a part uses the most appropriate materials and processing. The second major step was creating an optimization center with the powerful software engineers need to determine such things as where strength and durability are important in a design and where parts may be able to use less material without compromising performance. The standard and optimization center were critical to get in place before the company begins reporting on its overall progress toward meeting the goal. Cummins uses to how they are processed, to ensuring raw materials can be used again for another life. Leaders hope the goal will optimize Cummins’ resource use, as well as enable the company’s low-carbon transformation, while continuing to power customer success and maintain the economic benefits society depends on. COMPANY BUILDS FOUNDATION TO MEET LIFECYCLE PLANNING GOAL As Cummins looks toward its 2050 aspirational target of nothing wasted, the company knows it will require a shift in how Cummins thinks about materials and waste. Wasting nothing is also about being even more vigilant in using materials at their highest value for as long as possible. The goal is ultimately about waste minimization through material efficiency and reducing the company’s use of natural resources by design, from the raw materials GOAL 5: Create a circular lifecycle plan for every part to use less, use better, use again.

Looking ahead, Cummins’ Returnable Packaging Management Program has significant investments planned over the next five years in returnable packaging, tracking software, third party logistics, packaging services, warehousing, and more. These improvements will be instrumental to achieving 78 million pounds of packaging waste reduction, helping the company achieve its overall 2030 waste reduction goal. However, Cummins saw packaging waste increase by 3.3 million pounds, a 2% absolute increase. Process-derived waste increased by 7 million pounds, a 10% absolute increase, and e-waste increased by 1.6 million, 3.75 times larger than 2018. The company has launched initiatives to reduce packaging waste, process-derived waste (such as used oil, coolants, paints and solvents) and general refuse. In 2021, the company reduced general waste by 15% from 2018. This reduction is mainly attributed to closures of most office spaces and cafeterias due to the pandemic. Cummins’ packaging strategy has laid out an important path to achieving the company’s goals and aspirations. In 2022 alone, global packaging waste reduction projects are expected to reduce 1.3 million pounds of waste while providing a cost avoidance of $3 million. Cummins will achieve this through intercompany reuse of expendable packaging, implementing returnable solutions for engine blocks, battery packs and other prioritized parts; expanding leased and supplier owned returnable packaging in India and China; CUMMINS MAKES PROGRESS ON WASTE REDUCTION GOAL In its 2030 goals, Cummins is shifting focus from the company’s 2020 goal around recycling waste to producing less waste in the first place. Cummins has examined the company’s processes and practices to identify and implement immediate changes as well as transformational projects to achieve both its 2030 waste reduction goal and the company’s 2050 aspiration to use natural resources in the most sustainable way. In 2021, Cummins achieved a 4.1% waste reduction as a percent of revenue from the company’s 2018 baseline and an absolute generation reduction of 3%. Metal scrap decreased by 20 million pounds (a 8% absolute reduction), general refuse declined by 8 million pounds (a 15% absolute reduction).

      2021 SUSTAINABILITY PROGRESS REPORT | Cummins Inc. ENVIRONMENTAL PROGRESS // 26 MORE WORK NEEDED BEFORE PROGRESS CAN BE MEASURED ON PLASTICS GOAL This 2030 goal is still largely in the planning phase. Opportunities for progress have been identified, but more work is necessary before metrics are available to measure progress. A key action under discussion is the use of universally recyclable packaging content and eliminating problematic materials such as foam and mixed material packaging. This step, however, requires partnerning with suppliers on design and material selection and is a longer-term effort. The single-use plastics part of the goal has been limited in its progress during the pandemic, as many employees had not yet returned to their work locations in 2021 and the focus of site facility staff was on pandemic protocols. GOAL 7: Reuse or responsibly recycle 100% of packaging plastics and eliminate single-use plastics in dining facilities, at employee events and as amenities. NEAR NET ZERO LOGISTICS CENTER OPENS IN U.K A new Cummins logistics hub in Daventry, U.K., is being praised for its energy efficiency. The company’s United Kingdom Logistics Centre (UKLC), which opened in 2021, has been given a BREEAM Outstanding rating, a sustainability assessment ranking the facility in the top 1% of non-domestic buildings in the U.K. The UKLC is designed to be self-powered for half of the year, utilizing photo-voltaic solar panels on its roof capable of generating up to 1,472 kilowatts (kWp) and a Cummins QSK60G gas generator set in a standby application. Other environmentally focused features include the site’s ability to harvest rainwater and available electric vehicle charging stations for employees. The project also supported local businesses, using suppliers from within a 15-mile radius throughout construction. The developer offset the embodied carbon during the construction phase by participating in an effort to safeguard approximately 330 acres of rainforest.

The company joined the CEO Water Mandate, an extension of the United Nations’ Global Compact, in November 2019, and the related Water Resilience Coalition in 2021. Companies joining the coalition pledge to make the necessary investments in their own operations, as well as work together, to accomplish three goals by 2050:  A net positive impact in water-stressed areas.  Water resilience practices across a company’s value chain.  Collaboration to achieve water resilience. DOING OUR PART BY THE NUMBERS 672 Consumption target in millions of gallons of water use per year to reach 2030 reduction goal of 30%. 27 Cummins is already conserving millions of gallons of water through three relatively new on-site treatment systems at the Jamestown Engine Plant in Jamestown, New York; the Rocky Mount Engine Plant in Rocky Mount, North Carolina; and the Kothrud Engine Plant in Pune, India—three of the company’s largest plants. These multi-faceted systems are designed to treat water used at each location and return a significant amount to the plants for non- potable re-use. Cummins will continue to reduce water use through low- and no-cost efforts, notably fixing leaks and optimizing processes, and working to eliminate water use in them if possible. Finding alternative water sources or reusing water could include actions such as reuse of water from testing fire sprinklers and harvesting rainwater. The company has established some guidelines such as using treated wastewater whenever possible and utilizing fresh water for processes only after all other conservation options have been explored. Sites in water-stressed regions are working toward 100% wastewater reuse, including for irrigation. Cummins is moving away from water- intensive landscaping, using native grasses and other techniques more frequently in its landscaping as well as designs that keep rainwater on site rather than channel it to storm sewers. Efforts to meet the goal also include capital projects, primarily equipment efficiency upgrades and other high-impact projects such as single-pass cooling elimination, additional regenerative dynamometer installations to capture water used to cool test engines, and innovative wastewater reuse projects. CHALLENGING WATER GOAL PROMISES TO TEST COMPANY CREATIVITY Cummins’ PLANET 2050 water use goal is an absolute reduction of 30% by 2030, compared with the company’s 2020 goal, which was a reduction in water use intensity (water use adjusted by hours worked). In 2021, the company’s water use was 838 million gallons, a 12.7% reduction from the 2030 goal’s baseline year of 2018, but up 8.5% from 2020. Cummins used 960 million gallons of water in 2018, so a 30% reduction means reaching a consumption target of about 672 million gallons annually by 2030, even if the company grows. The 2030 goal is 100 million gallons below what the company consumed in 2020, when many Cummins facilities closed for significant time periods to help prevent the spread of COVID-19. Achieving that kind of reduction under more normal conditions will be a challenge. GOAL 8: Reduce absolute water consumption in facilities and operations by 30%.

The basin includes Cummins’ headquarters city of Columbus, Indiana. Cummins Water Works’ partnership with The Nature Conservancy is just one initiative the program has developed. To learn more, see the story ( page 41 ) in the Community Engagement section. In July of 2021, Cummins launched a new strategic initiative called Cummins Water Works to address the global water crisis. The program partners with leading water experts around the world to invest and engage in sustainable, large-scale, high impact water projects. The initiative is a major step forward toward PLANET 2050’s goal to produce net water benefits that exceed Cummins’ annual water use in all regions where the company does business. The program, supported by $8.5 million in Cummins grants, is initially focusing on four of the most water-stressed countries: Mexico, Brazil, India and the United States. By 2030, Cummins Water Works’ goal is to bring fresh water to more than 20 million people who would otherwise not have access to it. The program team quickly got to work, announcing on World Water Day (March 22, 2022) a $3 million, three-year grant to The Nature Conservancy to improve water quality in the Mississippi River basin in the United States. COMMUNITY ENGAGEMENT GOAL MOVING FULL STEAM AHEAD Cummins has long helped strengthen communities through its environmental volunteerism, engaging in numerous initiatives, from working with residents to safely preserve rainwater in impoverished neighborhoods outside São Paulo, Brazil, to helping villages establish sustainable water supplies near the company’s campus in Phaltan, India.

FLEET ELECTRIFICATION: Upgrade vehicle fleet electrification, onsite electrification for maintence and terminal trucks .

      2021 SUSTAINABILITY PROGRESS REPORT | Cummins Inc. India has been a point of emphasis in recent years for Cummins’ solar efforts with 20 installations since 2018 that together have a maximum potential output of 11-megawatts peak (MWp). The largest project in the country was a 1,250 kWp array during phase 2 of a solar initiative at the Kothrud Engine Plant in Pune, India. The total solar capacity at the plant is now 2,800 kWp, the largest installation in India. Cummins currently has plans for another 18 solar projects in 2022, with a special emphasis on China and the United States as the company’s efforts move forward. Solar will play a major role in meeting Cummins’ PLANET 2050 environmental goals. There have been significant technical improvements and price reductions that make it increasingly attractive as a low- carbon energy source. 30 ENVIRONMENTAL PROGRESS // SOLAR PLAYS KEY ROLE IN PATH TO 2030 GOALS After a record year for solar projects at Cummins in 2021, 2022 promises to be almost as busy as the company continues adding renewable, low- carbon solar power to its energy mix for plants and facilities. The company worked on 20 solar projects in 2021, ranging from a relatively modest 36-kilowatt peak (kWp) array that was phase 2 of a project at the Cummins Generator Technologies facility in Ahmednagar, India; to a 1,472 kWp installation atop the new U.K. Logistics Centre in Daventry, U.K.; to a 3,600 kWp array at the Rocky Mount Engine Plant in Rocky Mount, North Carolina (U.S.). When completed in 2022, the Rocky Mount solar array will be the second largest at Cummins, behind only the combined power of the 3,600 and 3,300 kWp installations atop two buildings that make up the Beijing Foton Cummins Engine Company campus in Beijing, China. The solar array at the company’s engine plant in Rocky Mount, North Carolina (U.S.) is expected to come on line in 2022. WIND PROJECT ADDS RENEWABLE ENERGY TO GRID Cummins continues to participate in a Virtual Power Purchase Agreement (VPPA) to support the expansion of a northwest Indiana wind farm. The 2017 agreement helped the Meadow Lake Wind Farm expand by guaranteeing a fixed price for its power. The expansion was completed in 2018 and began sending renewable energy to the grid in December of that year. Cummins’ share of the expansion was 75 megawatts of capacity. While none of the power generated goes directly to a Cummins’ facility, it essentially offsets all of the electricity used from traditional sources at company facilities across the state with renewable electricity. Cummins’ science based facilities- and-operations goal for greenhouse gas is calculated using market-based Scope 2 emissions, which include the impact of the VPPA.

The new goals and metrics build on Cummins’ 2020 goals. While the company did not achieve every 2020 goal, they drove significant benefits. The company achieved four of its seven principal 2020 goals, established as part of Cummins’ first sustainability plan in 2014:  Cummins reached a 53% reduction in water use adjusted by hours worked in 2020. The goal was a 50% reduction.  The company worked with customers to exceed the Cummins’ goal of a run-rate reduction of 3.5 million metric tons of carbon dioxide from the company’s products in use, achieving a 4.9 million reduction in 2020.  Thirty-five Cummins locations achieved the company’s definition of Zero Disposal sites— five above the goal of 30.  Sixteen Cummins sites achieved the company’s definition of Water Neutrality. Cummins’ goal was 15. Meanwhile, the company narrowly missed two goals. Cummins recorded a 93% recycling rate while the 2020 goal was 95%. The company was within a percentage point of reaching Cummins’ goal of a 32% reduction in energy use adjusted by hours worked and then fell back to a 27% cut in 2020, in part because of the pandemic. Company leaders say setting aggressive goals is important to achieve environmental progress.

      2021 SUSTAINABILITY PROGRESS REPORT | Cummins Inc. 32 The EPA’s GHG and fuel-efficiency regulations were required for all heavy- duty diesel and natural gas engines beginning in January 2014. Cummins’ GHG certification was the first engine certificate issued by the agency. Phase 2 of the U.S. GHG-fuel efficiency regulations, passed in 2016, includes separate engine standards. Cummins continues to support this approach. The company also continues working to reduce levels of NOx and PM in its product emissions both in the U.S. and globally. ADVOCATES FOR ACTION As attention has turned to the world’s climate challenges, Cummins has joined with like- minded companies to support climate action. Ahead of the global climate summit in Glasgow, Scotland (U.K.), in 2021, Cummins joined Business Ambition for 1.5°C, which encourages companies to set robust emission reduction goals for GHGs using science-based targets aligned to the 2015 Paris Climate Accords. By extension, the company also was accepted into the United Nations’ Race to Zero campaign, a global To achieve responsible regulations, the company is committed to working with the U.S. EPA, the California Air Resources Board, China’s Ministry of Environment and Ecology, the European Commission and other regulators as they develop new standards. Cummins work in this area is led by the company’s Product Compliance and Regulatory Affairs (PCRA) team. The team was created in 2019 to strengthen Cummins’ collaboration with agencies setting emissions regulations and certification processes. PCRA functions independently from, and provides oversight to, the product development teams and business segments at the company. The group’s leader reports directly to Cummins’ Chairman and CEO and is a member of two of the company’s top leadership teams. Keeping track of global standards is no small task. In 2020, the company certified or maintained more than 125 engine configurations with approximately 17 governing agencies around the world. These certifications represented at least 34 different emissions standards for diesel and natural gas products for on-highway, off-highway, marine and rail applications. Together, they enable the company to achieve four strategic goals:  The development of responsible regulations.  A balanced, global regulatory approach.  Incentives to accelerate progress on the environment.  Technology development. Here’s a closer look at each area, and how they work together to help Cummins accomplish those goals: REGULATORY SUPPORT Cummins supports tough clear and enforceable regulations. The company expects standards will continue to tighten for nitrogen oxides (NOx), particulate matter (PM), greenhouse gases (GHGs) and other emissions, not just in the United States, but around the world The company believes the technical knowhow of its employees give Cummins a competitive advantage in meeting tougher regulations, provided they are enforced equally to create a level playing field. PARTNERSHIPS AND ADVOCACY // THREE KEYS TO CUMMINS’ APPROACH TO ENVIRONMENTAL STRATEGY AND COMPLIANCE Regulatory support, policy advocacy, and effective partnerships all play critical roles in Cummins’ approach to environmental strategy and compliance.

      2021 SUSTAINABILITY PROGRESS REPORT | Cummins Inc. 125 Number of engine configurations certified or maintained by Cummins as it works with regulators around the world. 33 Cummins has also worked with the International Council on Clean Transportation, whose mission is to improve the environmental performance of on- and off-highway technologies to benefit public health. In 2021, the company produced 33,124 soot-free engines as part of a key ICCT initiative. Finally, Cummins is partnering with groups concerned more generally about sustainability, including BSR, a leader in helping its members develop sustainable business strategies. Cummins’ regulatory support, advocacy and its partnerships all inform the way the company’s Environmental Strategy and Compliance function carries out its work. This work is critical to the company’s efforts to be a leader on environmental sustainability. PARTNERSHIPS FOR PROGRESS The CEO Climate Dialogue is one of many partnerships the company engages in as the world begins the transition to a low- carbon economy. As Cummins becomes more involved in low- and no-carbon hydrogen platforms, these partnerships include the global Hydrogen Council, the U.S. Fuel Cell Hydrogen Energy Association, the California Hydrogen Business Council, the CA Fuel Cell Partnership, Hydrogen Europe and Hydrogen Forward. Linebarger sits on the board of the Hydrogen Council. Cummins also participates in the EPA’s Green Power Partnership and the Renewable Energy Buyer’s Association, which promote the use of low-carbon power sources such as wind and solar. In addition, the company works with groups such as the Diesel Technology Forum, which promotes the importance of clean diesel, and Cummins is a founding member of the Health Effects Institute, which, in partnership with the EPA, provides impartial, high quality scientific findings on air pollution. effort to rally leadership and support from businesses, investors, cities and regions for climate action. Both groups maintain acting now can address not only global environmental threats, but also create jobs, and unlock sustainable growth. Chairman and CEO Tom Linebarger and Vice President Amy Davis, President of Cummins’ New Power business segment, attended COP26 in Scotland as the company brings to market the low- and no-carbon technologies that will be needed to power the future. Finally, the company joined the CEO Climate Dialogue, a coalition of more than two-dozen businesses and institutions, including leading environmental groups, working together to advance federal climate policy in the United States. Members range from the Ford Motor Co. and Shell to the Environmental Defense Fund.

      2021 SUSTAINABILITY PROGRESS REPORT | Cummins Inc. 35 BUILDING MORE PROSPEROUS COMMUNITIES In 2021, Cummins continued to strengthen its long-standing commitment to improving the communities where the company does business and where its employees live and work. Cummins employees and leaders engage in their communities by identifying opportunities that they have a unique ability to address using their knowledge and skills. This work takes many forms, ranging fr om the company’s global strategic program to build technical vocational skills that can lead to well-paying jobs, to Cummins’ global initiative to accelerate gender equality for women and girls. While the pandemic has impacted employee in-person volunteerism, the company has continued its work to strengthen communities. In 2020, Cummins launched a strategic initiative, Cummins Advocating for Racial Equity ( page 40 ), to address systemic racism and injustice in the United States through economic empowerment, criminal justice reform, police reform and social justice. In 2021, the company announced Cummins Water Works, a new strategic environmental program to address the global water crisis in Cummins communities around the world. COMMUNITY ENGAGEMENT // Cummins employees work on an environmental project, one of three global priority areas for the company.

      2021 SUSTAINABILITY PROGRESS REPORT | Cummins Inc. 36 ENVIRONMENT Creating a net positive impact and near zero local environmental footprint. Cummins strives to make a net positive environmental impact in its communities through volunteerism and partnerships, so the company has a positive impact greater than its local environmental footprint. Among many initiatives to achieve Cummins’ environmental goals, Cummins Water Works (page 41) is a global strategic program to strengthen communities through sustainable water and address the global water crisis. EQUALITY OF OPPORTUNITY Increasing opportunity and equity for everyone. Cummins has a deeply rooted commitment to removing barriers for those who have historically been denied access to opportunity, including racial and ethnic minorities, women, people with disabilities, the economically disadvantaged, immigrants and refugees, and the LGBTQ+ community. Among many Cummins programs to build opportunity is Cummins Powers Women (page 39), a global strategic program to achieve gender equality.

CUMMINS TEC BY THE NUMBERS 38 He is thankful for his time in the Cummins TEC program and the connections he’s made with former classmates. “Some friends are working as technicians, some continued their education and are engineers, and some decided that being a technician was not their path. Most have related jobs now, largely due to the technical and soft skills we learned in the (TEC) program.” Cummins TEC increased its reach in the U.S. in 2021, launching new programs at two schools in Nashville, Tennessee, one of which is the first post-secondary school in the U.S. to implement a Cummins TEC program. Expanding Cummins TEC into these locations aims to improve pathways for Black students into prosperous careers. This goal links the program to CARE: Cummins Advocating for Racial Equity, a U.S. strategic community initiative focused on dismantling institutional racism and creating systemic equity launched in 2020. Together, these two Cummins initiatives seek to strengthen programs available to people of color and provide the skills needed to compete in the workforce. female. The company aspired to reach a goal of 8% female enrollment in TEC schools last year. To date, 2,713 young men and women have graduated from the program, with a total graduation rate of 78%. One such success story is Mert Karakus. He attended the first Cummins TEC cohort at Ege University in Izmir, Turkey, focusing on the mechatronics curricula and studying English. After graduation, he joined aerospace company Fokker in Turkey, eventually transferring to Toronto where he manufactures and supplies wiring harnesses for a variety of aircraft programs, specializing in Airbus harnesses. STRENGTHENING COMMUNITIES THROUGH VOCATIONAL EDUCATION To augment the company’s employee-led engagement and grantmaking, Cummins also focuses its resources and skills on addressing large global problems in its communities. In 2012, the company launched its first global strategic initiative called Cummins TEC: Technical Education for Communities, which seeks to transform lives through career technical vocational education by training disadvantaged youth in employable skills to gain good jobs. The program currently has 25 school programs in 12 countries around the world. 2021 saw the highest enrollment numbers since the program started, with more than 1,200 students enrolling around the world.

      2021 SUSTAINABILITY PROGRESS REPORT | Cummins Inc. 39 In Ghana, Cummins partners with Camfed to help disadvantaged young women from rural backgrounds navigate the post-school period and transition to further education, employment or entrepreneurship. Doris Afanyedey (left), General Manager of Cummins Ghana, helped launch a Cummins mentorship program for Camfed alumni. Cummins employees guide Camfed students through their educational and career journeys by sharing work related experiences. Afanyedey mentors because she feels it is her calling to help young women reach their full potential. One of her mentees was interested in nursing, so she encouraged the woman to create a vision board based on her educational and professional goals. It was a great way to establish objectives and identify areas where the young woman could use Afanyedey’s guidance. “When you mentor, you allow people to see that they can do so much more,” Afanyedey added. In North America, Girls Inc. and Cummins developed a direct mentoring program between nine Cummins leaders and nine Girls Inc. affiliate leaders. These relationships enabled the nonprofit leaders to explore career challenges, goals and development needs with senior Cummins executives. Girls Inc. leaders benefited from a fresh perspective on management issues like delegation, strategy setting, personnel and finance. The experience was positive for Cummins leaders, too. “The mentoring provides me an opportunity not only to share what we do but also challenge myself on why we do some of the things we do,” said Brian Mormino, Cummins Executive Director – Technical and Environmental Systems. “I am learning right alongside her and then adjusting what I do in Cummins. We are truly rolling up our sleeves together. Our discussions also force me to slow down and reflect on things I normally don’t make time for. In this way, we are both growing together.” GENDER EQUALITY INITIATIVE SEES SIGNIFICANT GROWTH IN 2021 Cummins’ second global strategic initiative, Cummins Powers Women, saw significant growth in the number of women and girls served by the program’s nine nonprofit partners in 2021. Since its launch in 2018, this $22 million commitment to advancing gender equality in Cummins’ global communities has enabled equal rights and opportunity for more than 946,000 women and girls in 17 countries. The program has funded 253 advocacy grants resulting in 34 gender equality law and policy changes that positively impacted the lives of 26 million women and girls. That is up from 17 million impacted in 2020. The program focuses on the four main drivers to achieving gender equality: educational attainment, economic empowerment, legal rights and personal safety. Mentoring was one opportunity for employee engagement that remained possible during the pandemic.

COMMUNITY ENGAGEMENT // STRATEGIC INITIATIVES CUMMINS WATER WORKS BY THE NUMBERS TWO 41 Through the program, Cummins is partnering with leading water experts and leveraging the company’s unique experiences, skills and capabilities to make a large-scale impact. Cummins joined the Water Resilience Coalition, a United Nations- sanctioned working group comprised of water-related nonprofit organizations, and more than a dozen major global companies focused on analyzing, prioritizing, implementing and managing high-impact water projects in major water-stressed regions around the world. At a virtual launch event, Cummins leaders and more than 600 employees from around the world provided a high-level look at how the program will operate, while emphasizing key connection points water has throughout the company. A program launch video illustrates the urgency and significance of the global water crisis. Cummins’ initial nonprofit partners are The Nature Conservancy and Water.org, both of which are focused on tackling the water challenge at a basin level as well as at the small business, household and individual level. Cummins regional leaders are working closely with nonprofit experts on five projects in India, Brazil and Mexico. By the end of 2021, the program committed $8.5 million in grants. Cummins Water Works aims to strengthen communities through sustainable water. Water stress is the most urgent environmental threat facing many Cummins communities and is a direct consequence of climate change. The program focuses on the collective action required to solve the growing global water crisis afflicting communities, which has direct negative effects on health, education, gender equity and the growth of entire economies. PLANET 2050 is Cummins’ metrics- based sustainability strategy focusing on operations, customers and supply chain. Cummins Water Works extends the company’s commitment to environmental sustainability, focusing on ensuring availability and sustainable management of water in Cummins communities. Today, about 785 million people lack access to basic drinking water, and by 2050 at least one in four people will likely live in a country affected by chronic or recurring water shortages. A problem this large requires coordinated action to effectuate sustainable solutions. Cummins Water Works specifically aims to bring fresh water to 20 million people who will not otherwise have access to it. NEW PROGRAM TARGETS GLOBAL WATER CRISIS In July 2021, Cummins launched a new global strategic initiative called Cummins Water Works to address the global water crisis, partnering with leading water experts and investing and engaging in sustainable, large scale, high impact water projects.

      2021 SUSTAINABILITY PROGRESS REPORT | Cummins Inc. 42 For the past decade, Cummins’ Incidence Rate and Severity Case Rate have consistently been significantly below comparable industry averages (see chart on page 44 ). But the pursuit of excellence in health and safety is a journey never truly done. In 2021, Cummins implemented a new initiative around a metric known by health and safety professionals as Potential Serious Injuries and Fatalities or PSIF. PSIF is based on understanding the underlying causes of potentially severe incidents to develop preventive actions that mitigate risk before a serious injury occurs. ENHANCING THE SAFETY CULTURE The global implementation of PSIF is among the most significant process changes ever made in health and safety at Cummins, replacing the company’s Major Injury and Dangerous Occurrence system that had been in place for more than 12 years.

HEALTH AND SAFETY //

      2021 SUSTAINABILITY PROGRESS REPORT | Cummins Inc. 43 2021 HIGHLIGHTS There were a number of highlights in 2021. The Contractor Safety Incidence Rate, for example, decreased from 0.63 in 2020 to 0.50 in 2021. The Technical Organization improved its Incidence Rate by 8.8% while Asia-Pacific and China improved their respective Incidence Rates by 39% and 32%. In other key developments:  Supervisor specific safety training was developed to help cultivate an ideal safety culture where supervisors understand their role in creating an environment in which employees feel safe to speak up and express their ideas and concerns.  The Health and Safety function collaborated with the company’s Health and Wellness team to develop a pilot training on emotional wellness, providing employees the tools to manage stress within the workplace.  Health and Safety also worked with the Global Manufacturing function to introduce collaborative robots to address certain ergonomic risks. MEETING A CHALLENGING ENVIRONMENT For example, after achieving in 2020 a record low Incidence Rate, the rate of recordable injuries, Cummins saw an increase in 2021 from 0.48 to 0.57. The 2021 rate was below the company’s 0.59 Incidence Rate in 2019, which at that time was the lowest Incidence Rate at the company since 2015. Cummins’ Severity Case Rate, the rate of lost or restricted workdays, increased to 0.28 in 2021 from 0.21 in 2020. In 2019, the rate was 0.23, a 15% improvement over 2018’s rate of 0.26. The company’s Ergonomics Incidence Rate, the rate of ergonomic injuries, increased to 0.17 in 2021, up from 0.12 in 2020. Cummins’ Health and Safety leaders note that the fourth quarter contributed the fewest recordable injuries in 2021, an indication that mitigation efforts, including working with sites to maintain a focus on safety amid the many challenges they faced, were working.

A Potential Serious Injury and Fatality is defined as a work-related incident that had the potential to lead to a serious injury or fatality if not for one or two factors. A serious injury is considered a life threatening injury or illness requiring medical intervention to prevent death, while a life altering injury or illness is something that results in a permanent loss of a body part or function.

Employees are strongly encouraged to report all incidents and potential incidents. Underscoring the importance of this new initiative was an uptick in several key safety metrics at Cummins in 2021 as the company confronted a rapid escalation in business following shut-downs in the immediate aftermath of the COVID-19 pandemic a year earlier.

CUMMINS’ 10 ETHICAL PRINCIPLES Cummins ethics and governance initiatives are built around the 10 Statements of Ethical Principles in the Code of Business Conduct : 01 We will follow the law everywhere. 02 We will embrace diverse perspectives and backgrounds and treat all people with dignity and respect. 03 We will compete fairly and honestly. 04 We will avoid conflicts of interest. 05 We will demand that everything we do leads to a cleaner, healthier, and safer environment. 06 We will protect our technology, our information and our intellectual property. 07 We will demand that our financial records are accurate and that our reporting processes are clear and understandable. 08 We will strive to improve our communities. 09 We will communicate honestly and with integrity. 10 We will create a culture where employees take responsibility for ethical behavior. 57 The Ethics and Compliance function at Cummins, which is celebrating its 10th anniversary in 2022, oversees the company’s ethics and compliance program. The function communicates frequently that employees play a critical role in maintaining the Code of Business Conduct by reporting any problems they see. Cummins has a strict no-retaliation policy protecting employees making reports in good faith. Employees can report potential code of conduct or policy violations in multiple ways. They can use Cummins’ external Ethics website, call the company’s Ethics Helpline, send an email to the Ethics and Compliance function or simply talk to their supervisor, Human Resources representative or a member of the company’s Legal function. Employees can remain anonymous, where allowed by law. These reporting options are included in onboarding, training, core policies, and in blogs and emails from the Ethics and Compliance function. Cummins has a global team of investigators to look into possible code or policy violations. In 2021, the team investigated 1,575 cases, about evenly divided between inside and outside the United States. Employees worldwide are required to comply with Cummins’ Code of Business Conduct, which is reviewed in onboarding and again during mandatory online training periodically over an employee’s time with the company. The Code of Business Conduct is available in 16 languages on the Ethics and Compliance intranet website for Cummins employees. In addition, all office and exempt/ salaried employees must certify they are in compliance with the code. More than 30,000 Cummins employees as well as the company’s Board of Directors completed the 2021 certification process. Cummins’ Supplier Code of Business Conduct aligns closely with the company’s code of conduct for employees. Suppliers must state they are in compliance with the Supplier Code of Business Conduct as a condition of doing business with Cummins. The supplier code states suppliers must treat all people with dignity and respect and provide a healthy and safe work environment for their employees. Both the Supplier Code of Business Conduct and Cummins’ Code of Business Conduct for employees recognize the right to join a union and prohibit forced or child labor of any kind as well as human trafficking. SUSTAINABLE SUCCESS STARTS WITH ETHICAL BEHAVIOR Cummins is committed to doing business the right way, competing fairly and honestly and following the law everywhere. The company believes ethical behavior on the part of every employee is foundational to Cummins’ sustainability. The company’s Code of Business Conduct is built around 10 ethical principles, beginning with the simple but all-encompassing directive that “We will follow the law everywhere.” The principles touch on nearly every aspect of working at Cummins, from embracing diverse perspectives to safeguarding the company’s technology and intellectual property, to protecting the environment and strengthening the communities where Cummins does business.

Courses were offered virtually with a special emphasis on anti-bribery and data privacy for the year. MAINTAINING THE CULTURE A significant aspect of the Ethics and Compliance function’s work involves making the most of online training as a means of reminding employees that Cummins’ value of integrity never wavers. The function in 2021 introduced new training content to offer a more modern feel, with additional vignettes and scenario-based training. The content continues to focus on issues such as anti-bribery, antitrust, and fair competition, but from a fresh perspective. Training topics are assigned on a cyclical basis over a period of several years, so an employee does not take a course on every compliance topic every year. In addition, some trainings target specific groups of employees who would find it most relevant. The function also developed scenario-based training in 2021 for nearly 2,000 supervisors designed to help them with the critical job of creating and maintaining an ethical culture. Finally, the function conducts ethics and compliance reviews of significant partners and distributors to confirm they share Cummins’ values. KEY TO THE NEXT CENTURY Cummins is entering an exciting period of change, not just in the power technologies it is improving and developing, but also in how the company produces those technologies and how employees work in light of the movement toward flexible and remote working arrangements. In the midst of all this change, company leaders know one aspect of working at Cummins must not be lost: the company’s commitment to ethical behavior. It was critical during Cummins’ first 100 years, and it will be key to the company’s success for the next century. * Substantiated cases are now calculated on cases only investigated through the Ethics Investigation Process. ** The termination rate is now calculated on substantiated cases and cases only investigated through the Ethics Investigation Process. *** The average days to close formula has been updated to account for missing dates in the data. CUMMINS SUPPLIER CODE OF CONDUCT The Cummins Supplier Code of Conduct applies to all businesses providing products or services to Cummins and its subsidiaries, joint ventures, divisions, or affiliates. Available in 15 languages, the supplier code is built around seven principles and helps Cummins ensure it is doing business with other companies around the world that share its values for these practices: 01 Obey the law everywhere. 02 Treat people with dignity and respect. 03 Avoid conflicts of interest. 04 Provide a safe and healthy workspace. 05 Protect Cummins technology, information, and intellectual property. 06 Protect the environment and conserve natural resources. 07 Assist Cummins in enforcing the code. Cummins requires a verification response from suppliers that they are following the Supplier Code of Conduct before they are added to the company’s supplier database. Cummins may visit facilities and conduct audits to ensur e compliance. ETHICS AND COMPLIANCE //

      2021 SUSTAINABILITY PROGRESS REPORT | Cummins Inc. ETHICS AND COMPLIANCE BY THE NUMBERS 59 In establishing the policy, Cummins assessed the company’s risk for violations, determining the greatest risk exists deep in the company’s supply chain. Outside vendors providing services such as catering or cleaning were also identified as areas to watch. All of these areas receive extra attention and oversight from the company. The Ethics and Compliance function is working to develop additional ways to monitor these often less visible elements of the company’s operations. Cummins is committed to supply chain transparency and ensuring its partners, especially in high risk areas, adopt measures to mitigate human rights risks. Suppliers are required to sign response forms agreeing to comply with the company’s Supplier Code of Conduct, which also specifically prohibits forced and child labor. Cummins will work with suppliers to either develop a plan for compliance or a strategy for exiting their relationship with the company. If any inappropriate behaviors or conditions viewed as systemic or critical are observed during supplier audits, the situation is reviewed with the Cummins Legal function for appropriate action. KEEPING HUMAN RIGHTS TOP OF MIND Cummins has long been committed to protecting human rights, both within the company and across its supply chain. For many years, the Cummins Code of Business Conduct has stated the company “will not tolerate child or forced labor anywhere and we will not do business with any company that does.” In 2018, Cummins officially adopted a separate Human Rights Policy to reinforce where the company stands on this important matter. The Cummins Human Rights Policy specifically prohibits all forms of compulsory labor, as well as human trafficking. It applies to the company, its joint ventures, affiliated companies, and Cummins’ suppliers. If Cummins doesn’t have a controlling ownership interest or management responsibility with a related entity, the policy states it will take steps to require compliance. In 2019, Cummins implemented company-wide training on human rights for employees working within the company’s supply chain. Cummins also began integrating provisions of the policy directly into the Eyes Open Audits conducted primarily by employees in the Purchasing function when visiting suppliers to check on worker safety, environmental concerns and other issues. ABOUT THE POLICY Here’s a quick look at Cummins’ Human Rights Policy: ADOPTION: Completed in December 2017, after a thorough review, the policy was officially published in January 2018. CONTENTS: The policy specifically precludes human trafficking and exploitation, forced labor, child labor, bonded and prison labor, and supports foreign and migrant worker rights. IMPACT: The policy applies to Cummins entities in which the company has a controlling ownership interest or management responsibilities, including subsidiaries and joint ventures. INSPIRATION: The policy was guided by the Universal Declaration of Human Rights, the International Labor Organization’s Declaration on Fundamental Principles and Rights at Work, the United Nations Global Compact and the U.N.’s Guiding Principles on Business and Human Rights. SUPPLIERS: Cummins commits to supply chain transparency, pledging to work with suppliers and partners in high-risk locations to mitigate the risk of human trafficking and other human rights violations.

      2021 SUSTAINABILITY PROGRESS REPORT | Cummins Inc. GETTING THE MESSAGE OUT Cummins designates October as Cybersecurity Awareness Month. Global Cybersecurity team members and leaders go out and speak about the importance of cybersecurity in a variety of settings and multiple locations across the company. The team has also established a Cybersecurity Ambassador program, providing participants with the information they need to talk to their co-workers about the importance of protecting Cummins’ digital resources and information. 60 INNOVATIVE INITIATIVES Anyone with a Cummins account, including contract and joint venture workers, also has the ability at the press of a button to report suspicious emails. The company is constantly testing and implementing tools to detect anything outside of normal operations such as malware. In addition to new tools, the cybersecurity team collaborates with the business to conduct vendor security assessments to ensure vendors have adequate security measures in place before being entrusted with Cummins data. Finally, in a world that is increasingly interconnected, Cummins Global Cybersecurity is engaged in product development early on to maintain the highest levels of protection for the company’s products against cyber threats. TRAINING AND EDUCATION In addition to implementing the hardware and software necessary to protect the company from cyber threats, Cummins Global Cybersecurity has also worked to engage Cummins employees in its efforts through training and education, starting from revised global onboarding materials, where new employees first learn about the importance of protecting the company’s data and information. Employees who receive access to Cummins’ digital network receive training on the devices they use, including cybersecurity training, and the company is expanding training to employees who don’t have direct access to the network. Cummins expanded its required online training for employees with access to the company’s digital network. In 2021, more than 28,000 employees completed mandatory online training on data privacy. Global Cybersecurity also began sending out monthly emails to the more than 65,000 people enrolled in its training and awareness program testing whether they can successfully identify phishing attempts. Based on actual emails Cummins employees received, the exercise includes links to additional training for those who need it. A SOLID FOUNDATION Cummins Global Cybersecurity starts with a solid foundation, built on 21 separate policies governing different aspects of cybersecurity at the company. The function reports to Cummins’ Chief Information Officer, who regularly updates the company’s Board of Directors. Cummins is aligned to the cybersecurity framework developed by the U.S. Commerce Department’s National Institute of Standards and Technology (NIST) Cybersecurity Framework (CSF). All Cummins personnel, including temporary employees, contractors, and business partners handling information on the company’s behalf, are required to follow the data protection requirements contained in Cummins’ policies and procedures. The company has used outside experts to review its operations and evaluate Cummins Global Cybersecurity’s maturity and goals in alignment with NIST. Cummins benchmarks the function against peer companies and continually enhances its cybersecurity operations to meet the changing security landscape. CYBERSECURITY KEY COMPANY PRIORITY With much of the Cummins workforce working remotely in 2021, the company spared no efforts to keep its computer systems secure. Cummins is committed to protecting its intellectual property, customer data, and employee data, as well as the data increasingly important to product innovation and reliability, and the computer systems and networks critical to keeping nearly 65,000 global members of the Cummins workforce (employees, contractors and others) aligned and moving forward. As a global power technology leader, Cummins believes its holistic approach to cybersecurity, including advanced technologies, good governance, extensive employee training, and innovative programming, is the best approach to achieving its goals of protecting the company from increasingly sophisticated attacks. CYBERSECURITY //

      2021 SUSTAINABILITY PROGRESS REPORT | Cummins Inc. 61 TRACKING FUTURE RISKS The Executive Risk Council and the Board of Directors re-evaluated in 2020 how the company traditionally tracks risks, seeking to also track longer-term issues with the potential to significantly alter the way the company works. The company decided it was important to begin tracking a new category of risk in addition to the current enterprise risks. These “emerging risks” did not necessarily present an immediate or large threat to the company but have been identified as potentially important in the future. By continually taking steps to identify emerging risks, Cummins’ leaders and board keep an eye on the future while addressing the most material risks facing the company today. This process ensures leaders are always thinking about the company’s long-term sustainability. The Cummins Board of Directors oversees the most significant risks. The board or its committees receive briefings at every regular meeting on one or more relevant risks and once a year the full board reviews the entire Enterprise Risk Management program and the results of the last enterprise risk assessment. COORDINATION IS KEY Cummins’ Enterprise Risk Management team also works with other assurance groups that play an important role in managing risk throughout the company, including Risk Insurance and Global Security, which oversees the Business Continuity Plans established by every Cummins location to manage through an emergency. These plans are regularly tested and improved as part of Global Security’s holistic approach to emergency management. Key sites undergo tabletop exercises to ensure they are ready if an emergency occurs. The Risk Management team also works with the company’s Area Business Organizations on the risk management programs in their regions to track and mitigate key risks. A company’s ability to anticipate and manage potential business interruptions can be the difference between success and failure, whether the risk involves a supply chain disruption, an emissions compliance issue, or a cybersecurity concern—three of nearly two-dozen areas actively tracked by Cummins’ senior leadership. LEADERS PLAY MAJOR ROLE The Cummins Executive Risk Council is comprised of the company’s President and Chief Operating Officer, Vice Chairman, Chief Financial Officer, General Counsel, and Chief Administrative Officer. The Vice President – Corporate Strategy, Corporate Controller and the Vice President of Internal Audit also attend these meetings. The council meets at least quarterly to review and update material risks facing the company. Senior leaders are assigned responsibility for managing key risks. At every meeting a few of these risk “owners” present an in-depth briefing on their particular risk. Council members ask questions and debate the risk to ensure it gets the appropriate amount of attention. RISK MANAGEMENT FOUNDATIONAL TO CUMMINS’ SUSTAINABILITY Cummins’ Enterprise Risk Management team works with the company’s top leaders to establish a culture where key risks are identified and responded to appropriately, with guidance and oversight from Cummins’ Board of Directors. Company leaders believe managing risk is critical to Cummins’ long-term sustainability, and that effective risk management starts with enterprise resiliency. RISK MANAGEMENT //

      2021 SUSTAINABILITY PROGRESS REPORT | Cummins Inc. 62 The act also provides opportunities to invest in both low carbon and zero emission school and transit bus technology, and to build out the national charging infrastructure necessary for them. Additionally, the legislation contains significant funding for grid modernization, additional smart transmission, and distribution infrastructure to support more renewable energy development. The IIJA passed after extensive engagement with Congress and the Administration and will provide opportunities for ample investment in advanced technologies across the United States. WORKING WITH REGULATORS In Europe, the Government Relations team has been involved in mitigating the policy risks related to internal combustion engine technologies to ensure the focus is on improving environmental performance. On the implementation of the Euro VII emission standards, leaders from Product Compliance and Regulatory Affairs at Cummins met with high-level officials from the European Commission on several occasions to discuss challenges linked to the future regulation. The Government Relations team in Latin America, meanwhile, worked with Dual Carbon Initiative to promote alignment between carbon, pollutant emission and fuel efficiency. In Brazil, Cummins joined the Sustainable Low Carbon Movement to assist policy makers in their development of a strategic plan for a path to zero emissions. This plan will help frame the phases of the automotive policy in the country. Additionally, Cummins identified opportunities for new technologies and participated in the inauguration of the first hydrogen Cummins Electrolyzer and Fuel Cell project in Brazil. Finally, at the close of 2021, after years of advocacy from the business and social community alike, Congress passed the Infrastructure, Investment and Jobs Act (IIJA) and President Biden signed it into law. The IIJA includes several provisions that Cummins advocated for over the past four years, including in the Congressional testimonies of Cummins’ Tony Satterthwaite, Vice Chairman, and Dr. Wayne Eckerle, Vice President – Solid Oxide and Advanced Technology Exploration. The legislation will allow, for example, investment in hydrogen, including requiring the U.S. Government to propose a national hydrogen strategy, and build cross-sectoral hydrogen hubs across the country. ADVOCATING FOR CLIMATE ACTION Cummins Chairman and CEO Tom Linebarger and Amy Davis, the company’s Vice President and President of Cummins’ New Power business segment, attended the United Nations Conference of Parties 26th climate change (COP26) summit in Glasgow, Scotland. The event provided the company an opportunity to champion Cummins’ investment in the technologies of the future and engage with high level government officials and business leaders focused on the world’s climate challenges. The company also worked on Fit for 55, the European Union plan to reduce GHG emissions 55% by 2030. The climate initiative deals with renewable energy, taxation, and infrastructure, with the goal of strengthening the role of new and cleaner technologies in the path-to-zero emissions. Cummins also promoted hydrogen internal combustion engine technology to different policy leaders across the continent as an important step to reduce carbon quickly that should be encouraged to achieve a no-carbon economy. The company advocated for a similar approach in China with hydrogen internal combustion engines, engaging on China’s GOVERNMENT RELATIONS PARTNERS FOR PROGRESS ON SUSTAINABILITY The Cummins Government Relations function partners with business leaders to advocate for a positive business environment that fosters profitable growth, a cleaner environment, and more prosperous communities. 2021 was a historic year for climate and infrastructure policy. The Government Relations team worked to educate policymakers on the company’s commitment to Destination Zero , Cummins’ strategy to reduce greenhouse gases (GHGs) and improve air quality, and the importance of federal, state and local investment in low carbon and zero emission fuels, now and in the future.

In both Tennessee and South Carolina, Government Relations is working with local community and advocacy groups to identify legislative opportunities and assist their efforts. COVID-19 PANDEMIC RESPONSE In Latin America, Cummins engaged in advocacy to accelerate COVID-19 vaccinations in the region and support the necessary infrastructure to expedite the process. In Brazil, the Government Relations function joined the Movement United for Vaccines, a community organization focused on encouraging people to get vaccinated against COVID-19 in areas where Cummins employees live and operate. At the Cummins facility in Juárez, Mexico, the function worked with the federal, state and local government to increase the availability of the vaccine for employees and the larger community. Thanks in part to those efforts, 20,000 people received vaccinations as more than 350 Cummins employees invested over 1,800 hours of community work. There was nearly a 100% vaccination rate among employees in the region. educational opportunities to help Cummins employees understand the issue and take action through partnerships and webinars. On free trade, Cummins has continued to be deeply engaged in U.S.-China trade relations in 2021. Linebarger, in his role as Chairman of the U.S.-China Business Council, has been a leading voice within the business community on finding areas where the two countries have common policy goals. In particular, he has been encouraging collaboration on climate priorities. RACIAL EQUITY As part of the company’s Cummins Advocating for Racial Equity (CARE) initiative in the United States, Cummins Government Relations led advocacy efforts in Indiana, leading to the formation of the INSPIRE racial equity coalition. This coalition aims to bring Indiana-based corporations and advocacy organizations together to move proactive legislation and defend against regressive proposals. The function also assisted CARE leadership in making connections with community partners in Minnesota, Tennessee, and South Carolina to pursue police and criminal justice reform measures. policymakers and business leaders across the region to ensure emissions standards for nitrogen oxides (NOx) and particulate matter (PM) standards were strict but achievable with available technology, especially in the off highway and power generation market segments. In the United States, Government Relations worked closely with Product Compliance and Regulatory Affairs to promote tough, clear, and enforceable environmental regulations. Over the past year, the team advocated to Congress and the Environmental Protection Agency (EPA) for an environmentally protective and durable rule while awaiting the Clean Trucks Plan regulation for NOx and carbon dioxide (CO 2 ) reductions. VOTING RIGHTS AND FREE TRADE Following unprecedented voter turnout in 2020 and the expansion of early and mail-in voting options due to the pandemic, there was an uptick in restrictive legislation at the state level. The Government Relations function actively advocated against these efforts, including restrictions proposed in Indiana during the 2021 legislative session that were ultimately not adopted. Government Relations also engaged with leading voting rights groups to provide CUMMINS AND REGULATIONS Cummins has long supported tough, clear and enforceable regulations that drive innovation in the commercial power industry. The company has supported greenhouse gas/fuel efficiency regulations in the United States as well as national and regional efforts to reduce nitrogen oxides (NOx) and particulate matter (PM), key ingredients in smog. In China and India, the Government Relations team has engaged with policymakers to ensure NOx and PM standards are fully implemented and enforced. These engagements, along with additional advocacy by the team, is how Cummins uses its voice and its technology leadership to inform governments about the policies that will lead to a more sustainable future.

      2021 SUSTAINABILITY PROGRESS REPORT | Cummins Inc. 65 largest PEM electrolyzer in Bécancour, Canada. The company has produced more than 6,200 battery modules and packs as part of its work on battery-electric technologies. Finally, the global power leader has deployed more than 2,000 hydrogen fuel cells, powering a number of global firsts, including the world’s first hydrogen- powered passenger train with Alstom. In short, Cummins has the reach, experience and capabilities of a 102-year- old company, with the mindset of a startup. “The decarbonization of our economy is critical to our way of life and our industry will play a key role in that effort,” Cummins Chairman and CEO Tom Linebarger told financial analysts in early 2022. “Fortunately, decarbonization is also a growth opportunity for Cummins. We are confident in our ability to play a leading role in bringing lower carbon technologies to commercial vehicle and industrial markets globally.” IMPROVING CORE TECHNOLOGIES Cummins’ track-record on innovation goes back to the company’s formative days when founder Clessie Cummins first began experimenting with diesel engines. Internal combustion engines remain part of the company’s plans, but with continuing improvements to reduce carbon using the company’s core technologies. Cummins believes it is important to begin carbon reductions as quickly as possible to achieve the world’s climate goals. Cummins announced in 2021 a number of initiatives aligned to Destination Zero , accelerating development of internal combustion engines fueled by low-carbon hydrogen for commercial-industrial markets, launching a new near-zero emission natural gas engine for heavy-duty trucks, and, in early 2022, unveiling plans for internal combustion engines with a common architecture capable of optimization for the low-carbon fuel they use. The company in 2021 also opened a fuel cell systems production facility in Herten, Germany, and announced plans to build a new plant in Spain to manufacture electrolyzers, critical technology for increasing the supply of no-carbon, green hydrogen. In addition, Cummins unveiled a partnership to pursue large scale hydrogen production projects in Europe and a joint venture to produce green hydrogen in China. Cummins has now deployed more than 600 electrolyzers, including the world’s CUMMINS’ COMMITMENT TO DECARBONIZATION DRIVES INNOVATION The past year will likely go down as one of Cummins’ most innovative, as the company worked to reduce the carbon impact of its core products and bring to market the low-carbon technologies that will power the future—all while maintaining the durability and dependability customers count on. It’s part of Cummins’ Destination Zero strategy for decarbonization: investing in and advancing zero emission technologies for those customers who are ready while providing those who aren’t—either because of economic concerns, the absence of infrastructure, or other reasons—the chance to achieve critical carbon reductions INNOVATION // Fuel agnostic engines use common architectures for blocks and other core engine parts (red) while the engine can be optimized (gray) for a specific lower-carbon fuel.

      2021 SUSTAINABILITY PROGRESS REPORT | Cummins Inc. 66 RESEARCH AND DEVELOPMENT Cummins topped $900 million in spending on research, development and engineering expenses for a fourth consecutive year in 2021. $754 MILLION $902 MILLION $1 BILLION $906 MILLION $1.1 BILLION 2017 2018 2019 2020 2021 $754 MILLION $735 MILLION $637 MILLION 2016 2014 2015 2016 COMPANY RECORD engines to provide customers a competitively priced option to reduce carbon emissions. A month later, in October 2021, the company said it was bringing to market in North America a 15-liter engine platform for heavy duty trucks that will begin with a near zero emission natural gas version and later be available in a variety of fuels from diesel to hydrogen, offering leading power and performance while meeting more stringent emission regulations. Finally, in February 2022, Cummins announced it would expand its industry- leading B, L and X-Series platforms to develop “fuel agnostic” internal combustion engines designed so they can be optimized for a particular low-carbon fuel while using engine blocks and core components that share common architectures. This would enable truck manufacturers to integrate a variety of fuel types across the same chassis, reducing total cost of ownership for end users. NEW POWER MOVES FORWARD Meanwhile, the company’s New Power business segment continued bringing to market the technologies that will power the future, especially in hydrogen related platforms. as much and as soon as possible while the infrastructure develops to support widespread adoption of no-carbon platforms. In January 2022, the company formally launched its Destination Zero strategy to achieve the company’s aspiration of powering customers with net-zero emission platforms by 2050. The strategy is designed to serve all of the company’s stakeholders, focusing on three key principles: achieving immediate and significant carbon reductions from Cummins products in use, growing the hydrogen economy, and improving the resiliency of the grid while decarbonizing it with renewable energy. By moving immediately to reduce carbon emissions from its core products compared to simply waiting for widespread adoption of zero emission technologies, Cummins estimates 1.4 gigatons of carbon can be avoided by 2035—the equivalent of taking every truck off the road today for three years. Even before Destination Zero was publicly unveiled, the company announced in September 2021 it was accelerating development of a hydrogen-fueled engine platform for its medium-duty 6.7-liter and heavy-duty 15-liter internal combustion NEW POWER FIRSTS Cummins New Power has been part of several industry firsts. Here are three:  Cummins is powering the world’s largest PEM electrolyzer in operation at 20 MW in Bécancour, Canada.  Company technology is powering the world’s first hydrogen-powered passenger train, operating across Europe.  Cummins technology is part of the world’s first hydrogen refueling station for ships, cars, trucks and industrial customers in Antwerp, Belgium. INNOVATION //

      2021 SUSTAINABILITY PROGRESS REPORT | Cummins Inc. INNOVATION BY THE NUMBERS 67 1.4 Gigatons of carbon avoided by 2035 through advances in Cummins’ core products vs. waiting for mass adoption of zero emission platforms. 1.1 BILLION Record amount in dollars spent on research, development and engineering expenses in 2021. 2,000+ Cummins fuel cells deployed around the world. 6,200+ Cummins’ battery modules and packs deployed. POSITIONED TO MAKE A DIFFERENCE Cummins has many distinct advantages in the drive to decarbonize, Linebarger told analysts. First, it has the global reach to make a difference, with plants and a service network literally around the world. No one has more application knowledge or experience with internal combustion engines as the platform transitions to low-carbon fuels. The company also has the resources to invest in no-carbon technologies such as battery-electric and hydrogen fuel cells as well as green hydrogen production. Finally, Cummins has long-established relationships with customers, regulators, universities and others expected to play a critical role in decarbonization. “We are uniquely positioned in the commercial-industrial space to provide solutions now, solutions in the medium-term, (and) solutions in the long-term that will meet both the needs of the planet and the needs of our customers,” Linebarger said. Just a month later, the global power leader and Sinopec, also known as the China Petrochemical Corporation, announced a joint venture to produce green hydrogen technologies in China. The joint venture wants to accelerate the affordability and availability of green hydrogen through technological innovation, and expand research and development as well as manufacturing capacity. Most recently, in February 2022, Cummins and Meritor, Inc. announced an agreement for Cummins to acquire the global leader in drivetrain, mobility and electric powertrain solutions for commercial vehicle and industrial markets. The integration of Meritor’s people, technology and capabilities will position Cummins as one of the few companies capable of providing integrated powertrain solutions across combustion and electric power applications. The company believes eAxles will be a critical integration point within hybrid and electric drivetrains. By accelerating Meritor’s investment in this technology, and integrating development within New Power, Cummins expects to deliver market-leading solutions to global customers. In May 2021, the company announced it had selected Spain for building one of the world’s largest electrolyzer manufacturing plants, scalable to 1 gigawatt per year. Cummins also unveiled a partnership with Iberdrola, a global leader in the transition to clean energy, to develop large-scale green hydrogen production projects in Spain and Portugal.

      2021 SUSTAINABILITY PROGRESS REPORT | Cummins Inc. 69 The company’s Supply Chain teams total more than 30,000 employees and operate a global network of more than 125 plants, 40 warehouses and a supply base of more than 25,000 suppliers. SUPPORTING RECORD PRODUCTION Global supply chain challenges became widespread toward the start of 2021, disrupting virtually every industry and market, impacting Cummins, its customers and the company’s suppliers. Cummins’ ability to continue navigating the ongoing challenges driven by COVID-19, while also addressing these new challenges, is a testament to employees across the organization. The ability of Cummins’ Supply Chain organization to work collaboratively was critical, as each function brought unique skills that enabled the company to maintain operations at Cummins’ manufacturing SPECIAL REPORT CUMMINS EMPLOYEES MEET SUPPLY CHAIN CHALLENGES After a year of navigating unprecedented challenges in 2020 due to the COVID-19 pandemic, Cummins’ Supply Chain employees continued their tremendous efforts in 2021, supporting record sales while navigating ongoing global supply constraints. The complex combination of pandemic- related effects, weather events, fluctuating demand, and disruptions in global parts supplies and transportation impacted most companies, including Cummins. The company’s Supply Chain organization worked around the clock to resolve these challenges, meet customer demand and, most importantly, keep Cummins employees safe. The Cummins Supply Chain organization is responsible for the production and distribution of the company’s broad portfolio of power solutions. It includes Cummins’ Manufacturing; Purchasing; Planning; Logistics; Quality; and Health, Safety and Environment functions, partnering with teams from across the company (Human Resources, Information Technology, Finance, Legal, Communications and more) to ensure the success of Cummins’ global operations. Cummins diversity, equity and inclusion efforts extend to the company’s supply chain where the company is working to attract more women to the manufacturing function. SUPPLY CHAIN //

      2021 SUSTAINABILITY PROGRESS REPORT | Cummins Inc. SUPPLY CHAIN BY THE NUMBERS 70 INTRODUCING RENEWABLE POWER Cummins teams are also working to meet PLANET 2050 goals by identifying opportunities to reduce greenhouse gas (GHG) emissions at Supply Chain sites. The company, for example, worked on a record 20 solar projects in 2021 to include renewable power in Cummins’ energy mix. These ranged from a relatively modest 36-kilowatt peak (kWp) array that was phase 2 of a project at the Cummins Generator Technologies facility in Ahmednagar, India, to a 3,600 kWp array at the Rocky Mount Engine Plant in Rocky Mount, North Carolina (U.S.). When complete, the Rocky Mount array will be the second largest at the company. Cummins currently has plans for another 18 solar projects in 2022, with a special emphasis moving forward on sites in China and the United States. 43 MILLION Number of surgical masks produced by the company to help prevent the spread of COVID-19 during the pandemic. 20 300+ Number of collaborative robots now in place at company locations to enhance safe work practices, productivity, efficiency and product quality. 100,000+ Times the company’s Safe Work Playbook has been accessed detailing company procedures and practices during pandemic. its facilities were able to quickly comply with local shutdowns and regulations. NAVIGATING PANDEMIC IMPACTS When the pandemic hit in early 2020, Cummins’ Supply Chain teams worked quickly to support the development of the Safe Work Playbook—a detailed resource that provided step-by-step instructions for working safely during the pandemic and shutting down and restarting operations. Implementing safe work protocols across all plants, warehouses and operations globally was imperative to ensure the continuity of Cummins’ operations—sites simply couldn’t stop operating. Today, the Safe Work Playbook , which is publicly available on cummins.com, is on its 35th revision and has been viewed more than 100,000 times since the start of the pandemic. The Cummins Manufacturing function installed mask manufacturing lines in three company plants located in Columbus, Indiana. (U.S.); San Luis Potosi, Mexico; and Pune, India. Cummins’ mask manufacturing teams would go on to produce and distribute more than 43 million masks. Today, the company has a healthy stockpile and has ceased manufacturing masks with creating a more dependable supply network. With high demand for premium freight, increasing transportation prices and disruptions related to weather and shutdowns, Cummins’ Logistics teams developed innovative solutions to ensure the continuity of parts and product delivery to Cummins’ customers. For example, they chartered private vessels to bypass backlogs at major ports and with major transportation suppliers and worked to decrease customer backorders. By the end of 2021, Cummins saw record shipments from its warehouses and reduced customer aftermarket backorders by more than 30%—a major shift compared to the industry as a whole since the start of the pandemic. The good news is that many supply chain constraints and disruptions that impacted Cummins early in the pandemic are either improving or showing signs they are starting to improve, alongside falling COVID-19 rates and the lifting of pandemic health and safety protocols in many regions of the world. Of course, Cummins is continuing to maintain a flexible approach based on the risk in specific regions—with the recent COVID-19 surge in China, for example, Cummins and and distribution sites while supporting the ever-changing needs of both employees and customers. The company’s Purchasing teams worked to manage supply shortages and ensure supplier continuity, especially relating to electronic chip recovery, to ensure Cummins was able to produce and deliver to its customers—particularly after a robust increase in demand in mid-to-late 2020. Throughout 2020 and 2021, these teams were able to reduce the company’s list of highly constrained parts by more than half, SUPPLY CHAIN // Number of solar projects worked on at Supply Chain sites across the company in 2021 to add renewable power to Cummins’ energy mix.

      2021 SUSTAINABILITY PROGRESS REPORT | Cummins Inc. 71 The past two years have been an important reminder that today’s supply chain is changing more rapidly and facing more challenges than at any time in the recent past. And people have learned the critical role supply chains play in their daily lives. Cummins has long been grateful for those working in these critical roles at the company, but especially now. risk levels to ensure employee safety remains a top priority. They are also establishing regular plant efficiency reviews to drive enhanced flexibility and identify opportunities to reduce costs where possible. The teams are also implementing a new risk assessment process, driving a robust supply recovery process to recover remaining constrained parts, and identifying opportunities to reduce logistics and transportation disruptions—among others. As Cummins’ New Power business segment continues to expand, the company’s supply chain must also adjust to support the changes in product technology driven by the company’s Destination Zero and PLANET 2050 goals to go further, faster to reduce greenhouse gas (GHG) and the air quality impacts of Cummins’ products. The company’s Supply Chain strategy team has been engaged in scaling up Cummins’ supply base and manufacturing capacity to support these goals and deliver increased demand volume for several New Power products globally. This work is currently focused on supporting deployment of new manufacturing plants supporting New Power products in China, Spain and North America over the next two to three years. software to wirelessly connect two or more remote individuals—to conduct employee training, site tours, supplier visits and more. Today, more than 200 devices across dozens of functions at Cummins are using the technology daily. Another prime example of this was the deployment of collaborative robotics commonly referred to as “cobots.” These robots work alongside and interact with humans in a shared workspace— to enhance safe work practices, productivity, efficiency and product quality within Cummins’ manufacturing sites. While the company was already implementing cobots before the pandemic, these efforts were expedited, and Cummins now has more than 300 cobots supporting dozens of manufacturing capabilities across sites globally. LOOKING AHEAD Today, Cummins’ Supply Chain teams are continuing to work on creating a more flexible, resilient and sustainable supply chain, focused on the company’s future growth. The teams have developed a process for ensuring the appropriate revision or removal of the company’s COVID-19 protocols, tracking EYES OPEN AUDITS Cummins is also committed to ensuring human rights are respected throughout its supply chain, both inside and outside the company. One way is through the visits Cummins personnel make to outside suppliers to check on a particular contract. These Cummins employees, most often Purchasing personnel, are trained to perform Eyes Open Audits where they look for signs of such things as human trafficking and child labor as they check on a supplier’s work. As part of the Eyes Open Audits, Cummins employees also look for potential health and safety issues as well as environmental problems. The pandemic has severely limited travel to outside suppliers by Cummins personnel, but leaders are hopeful they will increase in 2022. In 2019, the last full year before the start of the pandemic, company employees performed nearly 400 Eyes Open Audits. restrictions lifting in many regions of the world. The company continues to make masks available to employees who wish to wear them or for employees at sites located in regions at high risk for COVID-19. The pandemic also forced Cummins to think in new ways about working safely and effectively in a virtual or socially distanced environment. Technology played an important role in these efforts. For example, the company began using augmented reality remote assist technology—a technology that uses a headset and communications Cummins is continuing to make greater use of collaborative robots to enhance safe work practices, productivity, efficiency and product quality within Cummins’ manufacturing sites.
