Cintas Corporation (CTAS) Business

Cintas Corporation (Cintas, Company, we, us or our), a Washington corporation, helps more than one million businesses of all types and sizes, primarily in the United States (U.S.), as well as Canada and Latin America, get READY™ to open their doors with confidence every day by providing a wide range of products and services that enhance our customers’ image and help keep their facilities and employees clean, safe and looking their best. With products and services including uniforms, mats, mops, shop towels, restroom supplies, workplace water services, first aid and safety products, automated external defibrillators (AEDs), eye-wash stations, safety training, fire extinguishers, sprinkler systems and alarm testing, Cintas helps customers get Ready for the Workday®. Cintas was founded in 1968 by Richard T. Farmer when he left his family's industrial laundry business in order to develop uniform programs using an exclusive new fabric. In the early 1970's, Cintas acquired the family industrial laundry business. Over the years, Cintas developed additional products and services that complemented its core uniform business and broadened the scope of products and services available to its customers.

Cintas’ reportable operating segments are the Uniform Rental and Facility Services operating segment and the First Aid and Safety Services operating segment. The Uniform Rental and Facility Services reportable operating segment consists of the rental and servicing of uniforms and other garments, including flame resistant clothing, mats, mops and shop towels and other ancillary items. In addition to these rental items, restroom cleaning services and supplies and the sale of items from our catalogs to our customers on route are included within this reportable operating segment. The First Aid and Safety Services reportable operating segment consists of first aid and safety products and services, as well as workplace water services. The remainder of Cintas’ business, which consists of the Fire Protection Services operating segment and the Uniform Direct Sale operating segment, is included in All Other.

The following table sets forth Cintas' total revenue and the revenue derived from each reportable operating segment and the remaining operating segments included in All Other for the fiscal years ended May 31:

The transaction between Cintas and UniFirst is referred to herein as the "Transaction." In connection with the Transaction, UniFirst shareholders will receive the merger consideration, which consists of (i) $155.00 in cash and (ii) 0.7720 of validly issued, fully paid and non-assessable shares of Cintas common stock (with, if applicable, cash in lieu of fractional shares), in each case without interest and subject to any required tax withholding, and each applicable holder of such shares of UniFirst stock will cease to have any rights with respect thereto, except the right to receive the applicable merger consideration. Under the terms of the Merger Agreement, subject to the satisfaction (or, to the extent permitted by applicable law in accordance with the Merger Agreement, waiver) of certain conditions, Cintas will acquire all the outstanding shares of UniFirst common stock in a transaction

valued at approximately $5.5 billion. UniFirst is a North American company in the supply and servicing of uniform and workwear programs, facility service products, as well as first aid and safety supplies and services. On June 12, 2026, UniFirst announced that at UniFirst’s Special Meeting of Shareholders, UniFirst’s shareholders voted to approve the pending acquisition by Cintas.

The obligations of each of Cintas, Merger Sub Inc., Merger Sub LLC and UniFirst to complete the Transaction are subject to the satisfaction or (to the extent permitted by law) waiver by Cintas and UniFirst of the following conditions:

• the shares of Cintas common stock to be issued in connection with the mergers having been approved for listing on the NASDAQ, subject to official notice of issuance;

• any applicable waiting period (and any extension thereof) under the HSR Act relating to the completion of the mergers having expired or early termination thereof having been granted and any authorization or consent from a governmental authority required to be obtained with respect to the mergers under certain antitrust laws having been obtained and remaining in full force and effect;

• the authorization or consent of the applicable governmental authority in respect of certain of UniFirst's permits having been obtained and remaining in full force and effect; and

• no governmental authority of competent jurisdiction having issued or entered any order or promulgated or enacted any law after the date of the Merger Agreement having the effect of enjoining or otherwise prohibiting the completion of the mergers.

In addition, the obligations of each of Cintas, Merger Sub Inc. and Merger Sub LLC to complete the Transaction are subject to the satisfaction or (to the extent permitted by law) waiver by Cintas of the following conditions:

• since the date of the Merger Agreement, no event, circumstance, occurrence, effect, fact, development or change having occurred that had or would reasonably be expected to have, individually or in the aggregate, a “material adverse effect” on Cintas that is continuing.

The Transaction has not closed as of the date of the filing of this Form 10-K. We expect the Transaction to close in the second half of calendar 2026.

We provide our products and services to over one million businesses of all types, from small service and manufacturing companies to major corporations that employ thousands of people. This diversity in customer base results in no individual customer accounting for greater than one percent of Cintas' total revenue. As a result, the loss of one account would not have a material financial impact on Cintas.

The primary markets served by each of the Cintas operating segments are local in nature and highly fragmented. Cintas competes with national, regional and local providers, large national retailers and small local retailers as well as companies with a significant online presence and the level of competition varies at each of Cintas' local

operations. In addition, businesses may decide to perform certain services in-house instead of outsourcing these services. Product, design, price, quality, service and convenience to the customer are the competitive elements in each of our operating segments.

Within the Uniform Rental and Facility Services reportable operating segment, Cintas provides its products and services to customers via local delivery routes originating from rental processing plants and branches. Within the First Aid and Safety Services reportable operating segment and All Other, Cintas provides its products and services via its distribution network and local delivery routes or local representatives. At May 31, 2026, Cintas, in total, had approximately 12,500 local delivery routes, 484 operational facilities and 12 distribution centers.

Cintas is committed to sourcing responsibly. Cintas sources finished products from many outside suppliers. As mentioned on our website, www.cintas.com, each and every supplier must comply with a vendor code of conduct as a condition of doing business with Cintas. Cintas also conducts internal training to ensure that employee-partners who have direct responsibility for supply chain management are knowledgeable and aware of issues and concerns surrounding our supply chain. In addition to sourcing from third-party suppliers, Cintas operates five manufacturing facilities that provide for standard uniform needs. Cintas purchases fabric, used in the manufacturing of its products, from several suppliers. Cintas' ability to find qualified suppliers who meet its standards and to access products in a timely and efficient manner, is subject to ongoing market risks. For a discussion of the risks associated with sourcing that may materially impact Cintas, please see "Item 1A: Risk Factors - Risks Relating to Business Strategy and Operations."

Cintas is subject to a wide array of laws, government regulations, including environmental regulations, and standards in each domestic and foreign jurisdiction in which it operates. In addition to Cintas’ U.S. operations, which generated over 90% of its consolidated revenue in all periods presented, Cintas also operates its business through wholly owned subsidiaries in foreign jurisdictions, primarily in Canada. Compliance with these laws, government regulations, including environmental regulations, and standards requires the dedication of time and effort of employee-partners as well as financial resources.

Compliance with environmental regulations and prioritizing our environmental sustainability efforts are important to us as a good corporate citizen. Our journey started in 1929 during the Great Depression when Doc and Amelia Farmer collected shop towels that had been disposed by manufacturing facilities along the Ohio River. They washed, recycled and sold the clean towels back to companies. Today, the majority of our total Company revenue comes from our Uniform Rental and Facility Services reportable operating segment. Most of these items are cleaned and processed in ways that extend their lifespan and, when not in use, are re-stocked for future customers to maximize their lifespan. Our laundering processes generate far less wastewater than home laundering. Water discharged into the environment is treated at our operating facilities and in accordance with local discharge standards and permits. Our lasting commitment to the environment and our communities is evident from our processes and innovation, which are designed to ensure that our operational facilities are operating efficiently. Cintas is subject to various environmental laws and regulations, as are other companies in the uniform rental industry. The primary federal statutes that apply to our activities in the U.S. are the Clean Air Act, the Clean Water Act and the Resource Conservation and Recovery Act. We are also subject to the Superfund Amendments and Reauthorization Act of 1986, which imposes certain reporting requirements as to emissions of hazardous substances into the air, land and water. While environmental compliance is not a material component of our costs, Cintas makes capital expenditures and associated operating costs, primarily for water treatment and waste removal, on a regular basis in order to comply with environmental laws and regulations, to promote employee-partner safety and to carry out its environmental sustainability principles. Environmental spending related to water treatment and waste removal was approximately $30.0 million in fiscal 2026, approximately $29.0 million in fiscal 2025 and approximately $27.0 million in fiscal 2024. Capital expenditures to limit or monitor hazardous substances totaled approximately $5.8 million in fiscal 2026, approximately $4.8 million in fiscal 2025 and approximately $1.7 million in fiscal 2024.

In addition, health and safety regulations have necessitated, and may continue to necessitate, increased operating costs or capital investments to promote a safe working environment. Cintas is also required to comply with increasingly complex and changing laws and regulations enacted to protect business and personal data in the U.S. and other jurisdictions regarding privacy, data protection and data security, including those related to the collection,

storage, use, transmission and protection of personal information and other consumer, customer, vendor or employee-partner data. With respect to the laws and regulations noted above, as well as other applicable laws and regulations, Cintas’ compliance programs may under certain circumstances involve material investments in the form of additional processes, training, personnel, information technology and capital. In fiscal 2026, compliance with the applicable laws, government regulations, including environmental regulations, and standards did not have a material effect on Cintas’ capital expenditures or consolidated results of operations. For a discussion of the risks associated with government regulations that may materially impact Cintas, please see “Item 1A: Risk Factors—Legal and Regulatory Risks.”

Cintas’ key human capital management objectives are to attract, retain and develop talent to deliver on the Company’s strategy. To support these objectives, Cintas’ human resources programs are designed to: keep people safe and healthy; enhance the Company’s culture through efforts aimed at making the workplace more inclusive; acquire and retain diverse talent; reward and support employee-partners through competitive pay and benefit programs; develop talent to prepare them for critical roles and leadership positions; and facilitate internal talent mobility to create a high-performing workforce. The principles and values our employee-partners share are the driving force behind all our accomplishments. At May 31, 2026, Cintas employed approximately 48,100 employee-partners in our global workforce, of which approximately 800 were represented by labor unions.

Our primary areas of focus in managing our human capital include the following:

Corporate Culture

We believe that our culture at Cintas is just as essential as our products and services. Our culture impacts the quality of the employee-partners we hire, the way we communicate and interact with our customers and each other and our performance standards. Our culture is the cornerstone representing our values, our behaviors, our way of working and how we approach our business, which is strong relationships and a dedication to taking care of one another and our customers. We operate according to the Cintas Code of Conduct and Business Ethics, available on our website www.cintas.com, which mandates full compliance with applicable laws and regulations and helps to preserve the integrity of our Company.

Talent Development

Cintas is committed to actively recruiting, retaining, developing and advancing a talented workforce. We provide numerous training opportunities for our employee-partners, with a focus on continuous learning and development and methodologies to manage performance, provide feedback and develop talent. We offer a wide array of training solutions (classroom, hands-on and e-learning) for our employee-partners. Our talent development programs strive to provide employee-partners resources to achieve career goals and build management and leadership skills. We also have multiple Employee-Partner Business Resource Groups which help foster inclusion among all employee-partners to build awareness, recruit and retain a diverse workforce and support the overall success of Cintas. In

addition, we offer mentoring programs, a management trainee program and executive leadership programs to support the professional growth of our employee-partners and ensure we have the right succession plans in place.

Health and Safety

We aspire to achieve zero workplace injuries and collisions and provide a safe, open, healthy and accountable work environment for our employee-partners. To align with internationally recognized standards, we have implemented an occupational health and safety management system in accordance with the Occupational Safety and Health Administration (OSHA) that is modeled after the International Organization for Standardization (ISO) 45001 and OSHA Voluntary Protection Program (VPP). Employee-partners, contractors, vendors and visitors are all covered by the system, which focuses on worksite analysis, hazard prevention, training, management commitment and worker involvement. We are also committed to continuously improving performance through our employee-partner-driven Health and Safety Improvement Committees in every operation, while corporate health and safety employee-partners conduct annual reviews of our operations. Additionally, every year our employee-partners receive online, on-the-job and classroom training on over 50 health and safety topics, and all maintenance staff must complete our award-winning Maintenance Safety Certification process. Every Cintas driver completes monthly driver safety training courses and/or on-the-road skills evaluations. All production-related managers attend OSHA’s 10-hour safety training course, and each member of our Senior Management team takes the Management and Leadership Skills for Environmental Health and Safety Professionals Course, part of the Harvard T.H. Chan School of Public Health safety and health curriculum. In addition, we provide several channels for all employee-partners to speak up, ask for guidance and report concerns related to ethics or safety violations, and we seek to address those concerns and take appropriate actions to uphold our Cintas values and health and safety culture. Through these efforts, Cintas has reduced our recordable injury rate by over 80% since 2008, has been awarded 140 OSHA VPP Star sites, which is more than triple any other U.S. company, and has received numerous safety, health and ergonomics awards from national and international groups.

Employee-Partner Wellness

We are committed to the physical and mental health and wellness of our employee-partners. We provide our employee-partners and their families with access to a variety of health and wellness programs, including our long-running Live Well program that supports employee-partners on their health and wellness journeys. We provide free annual biometric screening and health assessments at work or offsite, a tobacco cessation program, weight management programs and an employee-partner assistance program, which offers advice on mental health, legal and financial issues.

Compensation Programs and Employee Benefits

Our compensation and benefits programs provide a total rewards package designed to attract, retain and motivate our employee-partners. In addition to competitive base salaries, the total rewards package (which may vary by position and country) includes, among other items, commissions, bonuses, long-term incentives, retirement savings plans, medical insurance, prescription drug benefits, dental insurance, vision insurance, accident and critical illness insurance, life and disability insurance, health savings accounts, flexible spending accounts and an employee-partner assistance program.

Cintas Corporation (Cintas, Company, we, us or our), a Washington corporation, helps more than one million businesses of all types and sizes, primarily in the United States (U.S.), as well as Canada and Latin America, get READY™ to open their doors with confidence every day by providing a wide range of products and services that enhance our customers’ image and help keep their facilities and employees clean, safe and looking their best. With products and services including uniforms, mats, mops, restroom supplies, first aid and safety products, fire extinguishers and testing, and safety training, Cintas helps customers get Ready for the Workday®. Cintas was founded in 1968 by Richard T. Farmer when he left his family's industrial laundry business in order to develop uniform programs using an exclusive new fabric. In the early 1970's, Cintas acquired the family industrial laundry business. Over the years, Cintas developed additional products and services that complemented its core uniform business and broadened the scope of products and services available to its customers.

Cintas’ reportable operating segments are the Uniform Rental and Facility Services operating segment and the First Aid and Safety Services operating segment. The Uniform Rental and Facility Services reportable operating segment consists of the rental and servicing of uniforms and other garments, including flame resistant clothing, mats, mops and shop towels and other ancillary items. In addition to these rental items, restroom cleaning services and supplies and the sale of items from our catalogs to our customers on route are included within this reportable operating segment. The First Aid and Safety Services reportable operating segment consists of first aid and safety products and services. The remainder of Cintas’ business, which consists of the Fire Protection Services operating segment and the Uniform Direct Sale operating segment, is included in All Other.

The following table sets forth Cintas' total revenue and the revenue derived from each reportable operating segment and the remaining operating segments included in All Other for the fiscal years ended May 31:

(In thousands) 2024 2023 2022 Uniform Rental and Facility Services $ 7,465,199 $ 6,897,130 $ 6,226,980 First Aid and Safety Services 1,067,334 951,496 832,458 All Other 1,064,082 967,143 795,021 Total Revenue $ 9,596,615 $ 8,815,769 $ 7,854,459

Additional information regarding each reportable operating segment and All Other is also included in "Item 8. Financial Statements and Supplementary Data," in Note 14 entitled Operating Segment Information of "Notes to Consolidated Financial Statements."

We provide our products and services to over one million businesses of all types, from small service and manufacturing companies to major corporations that employ thousands of people. This diversity in customer base results in no individual customer accounting for greater than one percent of Cintas' total revenue. As a result, the loss of one account would not have a material financial impact on Cintas.

The primary markets served by each of the Cintas operating segments are local in nature and highly fragmented. Cintas competes with national, regional and local providers, large national retailers and small local retailers as well as companies with a significant online presence and the level of competition varies at each of Cintas' local operations. In addition, businesses may decide to perform certain services in-house instead of outsourcing these services. Product, design, price, quality, service and convenience to the customer are the competitive elements in each of our operating segments.

Within the Uniform Rental and Facility Services reportable operating segment, Cintas provides its products and services to customers via local delivery routes originating from rental processing plants and branches. Within the First Aid and Safety Services reportable operating segment and All Other, Cintas provides its products and services via its distribution network and local delivery routes or local representatives. At May 31, 2024, Cintas, in total, had approximately 11,700 local delivery routes, 467 operational facilities and 12 distribution centers.

Cintas is committed to sourcing responsibly. Cintas sources finished products from many outside suppliers. As mentioned on our website, www.cintas.com, each and every supplier must comply with a vendor code of conduct as a condition of doing business with Cintas. Cintas also conducts internal training to ensure that employee-partners who have direct responsibility for supply chain management are knowledgeable and aware of issues and concerns surrounding our supply chain. In addition to sourcing from third-party suppliers, Cintas operates five manufacturing facilities that provide for standard uniform needs. Cintas purchases fabric, used in the manufacturing of its products, from several suppliers. Cintas' ability to find qualified suppliers who meet its standards and to access products in a timely and efficient manner, is subject to ongoing market risks. For a discussion of the risks associated with sourcing that may materially impact Cintas, please see "Item 1A: Risk Factors - Risks Relating to Business Strategy and Operations."

Cintas is subject to a wide array of laws, government regulations, including environmental regulations, and standards in each domestic and foreign jurisdiction in which it operates. In addition to Cintas’ U.S. operations, which generated over 90% of its consolidated revenue in all periods presented, Cintas also operates its business through wholly owned subsidiaries in foreign jurisdictions, primarily in Canada. Compliance with these laws, government regulations, including environmental regulations, and standards requires the dedication of time and effort of employee-partners as well as financial resources.

Compliance with environmental regulations and prioritizing our environmental sustainability efforts are important to us as a good corporate citizen. Our journey started in 1929 during the Great Depression when Doc and Amelia Farmer collected shop towels that had been disposed by manufacturing facilities along the Ohio River. They washed, recycled and sold the clean towels back to companies. Today, the majority of our total Company revenue comes from our Uniform Rental and Facility Services reportable operating segment. Most of these items are cleaned and processed in ways that extend their lifespan and, when not in use, are re-stocked for future customers to maximize their lifespan. Our laundering processes generate far less wastewater than home laundering. Water discharged into the environment is treated at our operating facilities and in accordance with local discharge standards and permits. Our lasting commitment to the environment and our communities is evident from our processes and innovation, which are designed to ensure that our operational facilities are operating efficiently. Cintas is subject to various environmental laws and regulations, as are other companies in the uniform rental industry. The primary federal statutes that apply to our activities in the U.S. are the Clean Air Act, the Clean Water Act and the Resource Conservation and Recovery Act. We are also subject to the Superfund Amendments and Reauthorization Act of 1986, which imposes certain reporting requirements as to emissions of hazardous substances into the air, land and water. While environmental compliance is not a material component of our costs, Cintas makes capital expenditures and associated operating costs, primarily for water treatment and waste removal, on a regular basis in order to comply with environmental laws and regulations, to promote employee-partner safety and to carry out its environmental sustainability principles. Environmental spending related to water treatment and waste removal was approximately $27.0 million in fiscal 2024, approximately $26.0 million in fiscal 2023 and approximately $22.0 million in fiscal 2022. Capital expenditures to limit or monitor hazardous substances totaled approximately $1.7 million in fiscal 2024, approximately $1.0 million in fiscal 2023 and approximately $0.2 million in fiscal 2022.

In addition, health and safety regulations have necessitated, and may continue to necessitate, increased operating costs or capital investments to promote a safe working environment. Cintas is also required to comply with increasingly complex and changing laws and regulations enacted to protect business and personal data in the U.S. and other jurisdictions regarding privacy, data protection and data security, including those related to the collection, storage, use, transmission and protection of personal information and other consumer, customer, vendor or employee data. With respect to the laws and regulations noted above, as well as other applicable laws and regulations, Cintas’ compliance programs may under certain circumstances involve material investments in the form of additional processes, training, personnel, information technology and capital. In fiscal 2024, compliance with the

applicable laws, government regulations, including environmental regulations, and standards did not have a material effect on Cintas’ capital expenditures or consolidated results of operations. For a discussion of the risks associated with government regulations that may materially impact Cintas, please see “Item 1A: Risk Factors—Legal and Regulatory Risks.”

Cintas’ key human capital management objectives are to attract, retain and develop talent to deliver on the Company’s strategy. To support these objectives, Cintas’ human resources programs are designed to: keep people safe and healthy; enhance the Company’s culture through efforts aimed at making the workplace more inclusive; acquire and retain diverse talent; reward and support employee-partners through competitive pay and benefit programs; develop talent to prepare them for critical roles and leadership positions; and facilitate internal talent mobility to create a high-performing workforce. The principles and values our employee-partners share are the driving force behind all our accomplishments. At May 31, 2024, Cintas employed approximately 46,500 employee-partners in our global workforce, of which approximately 1,000 were represented by labor unions.

Our primary areas of focus in managing our human capital include the following:

Corporate Culture

We believe that our culture at Cintas is just as essential as our products and services. Our culture impacts the quality of the employee-partners we hire, the way we communicate and interact with our customers and each other and our performance standards. Our culture is the cornerstone representing our values, our behaviors, our way of working and how we approach our business, which is strong relationships and a dedication to taking care of one another and our customers. We operate according to the Cintas Code of Conduct and Business Ethics, available on our website www.cintas.com, which mandates full compliance with applicable laws and regulations and helps to preserve the integrity of our Company.

Talent Development

Cintas is committed to the continued development of its employee-partners. We provide numerous training opportunities for our employee-partners, with a focus on continuous learning and development and methodologies to manage performance, provide feedback and develop talent. We offer a wide array of training solutions (classroom, hands-on and e-learning) for our employee-partners. Our talent development programs strive to provide

employee-partners resources to achieve career goals and build management and leadership skills. We offer mentoring programs, a management trainee program and executive leadership programs to support the professional growth of our employee-partners and ensure we have the right succession plans in place.

Health and Safety

We aspire to achieve zero workplace injuries and collisions and provide a safe, open, healthy and accountable work environment for our employee-partners. To align with internationally recognized standards, we have implemented an occupational health and safety management system in accordance with the Occupational Safety and Health Administration (OSHA) that is modeled after the International Organization for Standardization (ISO) 45001 and OSHA Voluntary Protection Program (VPP). Employee-partners, contractors, vendors and visitors are all covered by the system, which focuses on hazard prevention, training, management commitment and worker involvement. We are also committed to continuously improving performance through our Health and Safety Improvement Committees in every operation, while corporate health and safety employee-partners conduct annual reviews of our operations. Additionally, every year our employee-partners receive online, on-the-job and classroom training on over 50 health and safety topics, and all maintenance staff must complete our award-winning Maintenance Safety Certification process. Every Cintas driver completes monthly driver safety training courses and/or on-the-road skills evaluations. All production-related managers attend OSHA’s 10-hour Safety Improvement course, and each member of our Senior Management team takes the Management and Leadership Skills for Environmental Health and Safety Professionals Course, part of the Harvard T.H. Chan School of Public Health safety and health curriculum. In addition, we provide several channels for all employee-partners to speak up, ask for guidance and report concerns related to ethics or safety violations, and we seek to address those concerns and take appropriate actions to uphold our Cintas values and health and safety culture. Through these efforts, Cintas has reduced our recordable injury rate by over 80% since 2008, has been awarded 128 OSHA Star sites in the VPP, which is more than triple any other company in the U.S. and has received numerous safety, health and ergonomics awards from national and international groups.

Employee-Partner Wellness

We are committed to the physical and mental health and wellness of our employee-partners. We provide our employee-partners and their families with access to a variety of health and wellness programs, including our long-running Live Well program that supports employee-partners on their health and wellness journeys. We provide free annual biometric screening and health assessments at work or offsite, annual free flu shots, a tobacco cessation program, weight management programs and an employee-partner assistance program, which offers advice on mental health, legal and financial issues.

Diversity, Equity & Inclusion

Cintas supports diversity, equity and inclusion by fostering a respectful, creative and productive environment where all employee-partners can reach their full potential without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, disability or protected veteran status. We actively recruit, retain, develop and advance a diverse and talented workforce. We have six Employee-Partner Business Resource Groups, focused on Women, African Americans, Hispanic and Latin Americans, Asian American/Pacific Islanders, LGBTQ+ and Military and Veteran employee-partners. These groups provide platforms for our employee-partners to showcase skills, experiences and perspectives. The Employee-Partner Business Resource Groups also help foster inclusion among all employee-partners to build awareness, recruit and retain a diverse workforce and support the overall success of Cintas. We also have a diverse Management Trainee program that helps Cintas find and develop the best talent for our leadership pipeline, and we monitor representation across management positions. Cintas’ diversity, equity and inclusion efforts are led by our Senior Vice President of Human Resources and Chief Diversity Officer. This position reports to our Chief Executive Officer and works to help achieve our goals and obtain a diverse and talented workforce, which is critical to our success.

Compensation Programs and Employee Benefits

Our compensation and benefits programs provide a total rewards package designed to attract, retain and motivate our employee-partners. In addition to competitive base salaries, the total rewards package (which may vary by position and country) includes, among other items, commissions, bonuses, long-term incentives, retirement savings plans, medical insurance, prescription drug benefits, dental insurance, vision insurance, accident and critical illness insurance, life and disability insurance, health savings accounts, flexible spending accounts and an employee-partner assistance program.

(In thousands) 2022 2021 2020 Uniform Rental and Facility Services $ 6,226,980 $ 5,689,632 $ 5,643,494 First Aid and Safety Services 832,458 784,291 708,569 All Other 795,021 642,417 733,057 Total Revenue $ 7,854,459 $ 7,116,340 $ 7,085,120

Additional information regarding each reportable operating segment and All Other is also included in Note 15 entitled Operating Segment Information of "Notes to Consolidated Financial Statements."

We have operations throughout the U.S. and Canada and participate in a global supply chain. Since fiscal 2020, the existence of the novel strain of coronavirus (COVID-19) pandemic, the fear associated with the COVID-19 pandemic and the reactions of governments around the world in response to the COVID-19 pandemic to regulate the flow of labor and products and impede the business of our customers, impacted our ability to conduct normal business operations, which had an adverse effect on our business. Many of Cintas' customers were also impacted by the COVID-19 pandemic, and we saw an impact on some customer's ability to pay timely. While there was minimal disruption to our supply chain, Cintas did increase inventory, primarily personal protective equipment and facility services inventory, in response to the customer needs and demand associated with the safety and cleanliness requirements of COVID-19. The increase in inventory resulted in additional inventory reserves during fiscal 2022 and fiscal 2021. See Note 1 entitled Significant Accounting Policies of "Notes to Consolidated Financial Statements" for additional detail on the incremental reserves placed on inventory. The on-going roll out of the COVID-19 vaccines and gradual lifting of COVID-19 restrictions had a positive impact on our business during fiscal 2022. The impact of the COVID-19 pandemic is fluid and continues to evolve, and therefore, we cannot predict the extent to which our business, consolidated results of operations, consolidated financial condition or liquidity will ultimately be impacted. For more information, see the sections entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and “Risk Factors” within this Annual Report on Form 10-K.

We provide our products and services to over one million businesses of all types, from small service and manufacturing companies to major corporations that employ thousands of people. This diversity in customer base results in no individual customer accounting for greater than one percent of Cintas' total revenue. As a result, the loss of one account would not have a material financial impact on Cintas.

The primary markets served by each of the Cintas operating segments are local in nature and highly fragmented. Cintas competes with national, regional and local providers, large national retailers and small local retailers as well as companies with a significant online presence and the level of competition varies at each of Cintas' local operations. In addition, businesses may decide to perform certain services in-house instead of outsourcing these services. Product, design, price, quality, service and convenience to the customer are the competitive elements in each of our operating segments.

Within the Uniform Rental and Facility Services reportable operating segment, Cintas provides its products and services to customers via local delivery routes originating from rental processing plants and branches. Within the First Aid and Safety Services reportable operating segment and All Other, Cintas provides its products and services via its distribution network and local delivery routes or local representatives. At May 31, 2022, Cintas, in total, had approximately 11,300 local delivery routes, 462 operational facilities and 12 distribution centers.

Cintas is committed to sourcing responsibly. Cintas sources finished products from many outside suppliers. As mentioned on our website, www.cintas.com, each and every supplier must comply with a vendor code of conduct as a condition of doing business with Cintas. Cintas also conducts internal training to ensure that employee-partners who have direct responsibility for supply chain management are knowledgeable and aware of issues and concerns surrounding our supply chain. In addition to sourcing from third-party suppliers, Cintas operates five manufacturing facilities that provide for standard uniform needs. Cintas purchases fabric, used in the manufacturing of its products, from several suppliers. Cintas' ability to find qualified suppliers who meet its standards and to access products in a timely and efficient manner, is subject to ongoing market risks. For a discussion of the risks associated with sourcing that may materially impact Cintas, please see "Item 1A: Risk Factors - Risks Relating to Business Strategy and Operations."

Cintas is subject to a wide array of laws, government regulations, including environmental regulations, and standards in each domestic and foreign jurisdiction in which it operates. In addition to Cintas’ U.S. operations, which in fiscal 2022 generated over 90% of its consolidated revenue, Cintas also operates its business through wholly-owned subsidiaries in foreign jurisdictions, primarily in Canada. Compliance with these laws, government regulations, including environmental regulations, and standards requires the dedication of time and effort of employee-partners as well as financial resources.

Compliance with environmental regulations and prioritizing our environmental sustainability efforts are important to us as a good corporate citizen. Our journey started in 1929 during the Great Depression when Doc and Amelia Farmer collected shop towels that had been disposed of by manufacturing facilities along the Ohio River. They washed, recycled and sold the clean towels back to companies. Today, the majority of our total Company revenue comes from our Uniform Rental and Facility Services reportable operating segment. Most of these items are cleaned and processed in ways that extend their lifespan and, when not in use, are re-stocked for future customers to maximize their lifespan. Our laundering processes generate far less wastewater than home laundering. Water discharged into the environment is treated at our operating facilities and in accordance with local discharge standards and permits. Our lasting commitment to the environment and our communities is evident from our processes and innovation, which are designed to ensure that our operational facilities are operating efficiently. Cintas is subject to various environmental laws and regulations, as are other companies in the uniform rental industry. The primary federal statutes that apply to our activities in the U.S. are the Clean Air Act, the Clean Water Act and the Resource Conservation and Recovery Act. We are also subject to the Superfund Amendments and Reauthorization Act of 1986, which imposes certain reporting requirements as to emissions of hazardous substances into the air, land and water. While environmental compliance is not a material component of our costs, Cintas makes capital expenditures and associated operating costs, primarily for water treatment and waste removal,

on a regular basis in order to comply with environmental laws and regulations, to promote employee-partner safety and to carry out its environmental sustainability principles. Environmental spending related to water treatment and waste removal was approximately $22.0 million in fiscal 2022, approximately $19.0 million in fiscal 2021 and approximately $20.0 million in fiscal 2020. Capital expenditures to limit or monitor hazardous substances totaled approximately $0.2 million in fiscal 2022, approximately $1.0 million in fiscal 2021 and approximately $3.0 million in fiscal 2020.

In addition, health and safety regulations (including laws or regulations promulgated in response to the ongoing COVID-19 pandemic) have necessitated, and may continue to necessitate, increased operating costs or capital investments to promote a safe working environment. Cintas is also required to comply with increasingly complex and changing laws and regulations enacted to protect business and personal data in the U.S. and other jurisdictions regarding privacy, data protection and data security, including those related to the collection, storage, use, transmission and protection of personal information and other consumer, customer, vendor or employee data. With respect to the laws and regulations noted above, as well as other applicable laws and regulations, Cintas’ compliance programs may under certain circumstances involve material investments in the form of additional processes, training, personnel, information technology and capital. In fiscal 2022, compliance with the applicable laws, government regulations, including environmental regulations, and standards did not have a material effect on Cintas’ capital expenditures or consolidated results of operations. For a discussion of the risks associated with government regulations that may materially impact Cintas, please see “Item 1A: Risk Factors—Legal and Regulatory Risks.”

Cintas is in the midst of a comprehensive, enterprise-wide review of its business model as it relates to environmental, social and governance (ESG) opportunities, improvements and efficiencies. In 2021, Cintas announced our ambition to achieve Net Zero greenhouse gas (GHG) emissions by 2050. In fiscal 2022, Cintas expanded our ESG report to share our focus on making a positive impact through our key ESG priorities. This included work in areas of climate and energy initiatives, water interactions, materials and waste innovations, sustainable supply chain, diversity, equity and inclusion efforts, employee-partner development, safety and health strategy, human rights and labor rights positions and governance, ethics and integrity foundations. Cintas' most recent ESG report can be found on our website at www.cintas.com/esg.

Cintas’ key human capital management objectives are to attract, retain and develop talent to deliver on the Company’s strategy. To support these objectives, Cintas’ human resources programs are designed to: keep people safe and healthy; enhance the Company’s culture through efforts aimed at making the workplace more inclusive; acquire and retain diverse talent; reward and support employee-partners through competitive pay and benefit programs; develop talent to prepare them for critical roles and leadership positions; and facilitate internal talent mobility to create a high-performing workforce. The principles and values our employee-partners share are the driving force behind all our accomplishments. At May 31, 2022, Cintas employed approximately 43,000 employee-partners in our global workforce, of which approximately 1,000 were represented by labor unions.

Our primary areas of focus in managing our human capital include the following:

Corporate Culture

We believe that our culture at Cintas is just as essential as our products and services. Our culture impacts the quality of the employee-partners we hire, the way we communicate and interact with our customers and each other and our performance standards. Our culture is the cornerstone representing our values, our behaviors, our way of working and how we approach our business, which is strong relationships and a dedication to taking care of one another and our customers. We operate according to the Cintas Code of Conduct, available on our website www.cintas.com, which mandates full compliance with applicable laws and regulations and helps to preserve the integrity of our Company.

Health and Safety

We aspire to achieve zero workplace injuries and provide a safe, open and accountable work environment for our employee-partners. To enforce internationally recognized standards, we have implemented an occupational health and safety management system in accordance with the Occupational Safety and Health Administration (OSHA). Employee-partners, contractors, vendors and visitors are all covered by the system, which focuses on hazard prevention, training, management commitment and worker involvement. We are also committed to continuously improving performance through our Safety Improvement Committees in every operation, while corporate safety and health employee-partners conduct annual reviews of our operations. Additionally, every year our employee-partners receive online, on-the-job and classroom training on over 30 safety topics, and all maintenance staff must complete the Maintenance Safety Certification. Every Cintas driver completes monthly driver safety training courses or on-the-road skills evaluations. Every manager attends OSHA’s 10-hour Safety Improvement course, and each member of our Senior Management team takes the Management and Leadership Skills for Environmental Health and Safety Professionals Course, part of the Harvard T.H Chan School of Public Health safety and health curriculum. In addition, we provide several channels for all employee-partners to speak up, ask for guidance and report concerns related to ethics or safety violations, and we address those concerns and take appropriate actions to uphold our Cintas values and safety culture. Through these efforts, Cintas has reduced our recordable injury rate by over 75% since 2008, has been awarded 122 OSHA Star sites in the Voluntary Protection Program (VPP), which is more than double any other company in the U.S. and have received numerous safety, health and ergonomics awards from national and international groups.

Employee-Partner Wellness

We are committed to the health and wellness of our employee-partners. We provide our employee-partners and their families with access to a variety of health and wellness programs, including our long-running Live Well program that supports employee-partners on their health and wellness journeys. We provide free annual biometric screening and health assessments at work or offsite, annual free flu shot clinics onsite or offsite, a tobacco cessation program, weight management programs and an employee-partner assistance program, which offers advice on mental health, legal and financial issues.

In response to the COVID-19 pandemic, we utilized our Preparedness Plan and implemented controls that we consider to be in the best interest of our employee-partners and the communities in which we operate, and which comply with government regulations. Some of the controls implemented in response to the COVID-19 pandemic, include physical barriers, social distancing, remote-working where possible, travel restrictions, appropriate personal protective equipment and additional hygiene and cleaning regimes. Keeping people safe remains our top priority, and the diligence and flexibility of our employee-partners in complying with these new controls has allowed us to continue to focus on providing essential products and services to our customers, ranging from cleaning supplies, disinfectant services, hand sanitizer, scrubs, face masks and face shields.

Diversity, Equity & Inclusion

Cintas supports diversity, equity and inclusion by fostering a respectful, creative and productive environment where all employee-partners can reach their full potential without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, disability or protected veteran status. We actively recruit, retain, develop and advance a diverse and talented workforce. We have five Employee-Partner Business Resource Groups, focused on Women, African Americans, Hispanic and Latin Americans, Asian American / Pacific Islanders and Military and Veteran employee-partners. These groups provide platforms for our employee-partners to showcase skills, experiences and perspectives. The Employee-Partner Business Resource Groups also help foster inclusion among all employee-partners to build awareness, recruit and retain a diverse workforce and support the overall success of Cintas. We also have a Management Trainee program that helps Cintas find the best talent for our leadership pipeline, and we monitor representation across management positions. Cintas’ diversity, equity and inclusion efforts are led by our Chief Diversity Officer. This position regularly reports to our Chief Executive Officer and works to help achieve our goals and obtain a diverse and talented workforce, which is critical to our success.

Compensation Programs and Employee Benefits

Our compensation and benefits programs provide a total rewards package designed to attract, retain and motivate our employee-partners. In addition to competitive base salaries, the total rewards package (which may vary by position and country) includes, among other items, bonuses, long-term incentives, retirement savings plans, medical insurance, prescription drug benefits, dental insurance, vision insurance, accident and critical illness insurance, life and disability insurance, health savings accounts, flexible spending accounts and an employee-partner assistance program.

Talent Development

Cintas is committed to the continued development of its employee-partners. We provide numerous training opportunities for our employee-partners, with a focus on continuous learning and development and methodologies to manage performance, provide feedback and develop talent. We offer a wide array of training solutions (classroom, hands-on and e-learning) for our employee-partners. Our talent development programs strive to provide employee-partners resources to achieve career goals and build management and leadership skills. We offer mentoring programs, a management trainee program and executive leadership programs to support the professional growth of our employee-partners and ensure we have the right succession plans in place.

Cintas Corporation (Cintas, Company, we, us or our), a Washington corporation, helps more than one million businesses of all types and sizes, primarily in the United States (U.S.), as well as Canada and Latin America, get READY™ to open their doors with confidence every day by providing a wide range of products and services that enhance our customers’ image and help keep their facilities and employees clean, safe and looking their best. With products and services including uniforms, mats, mops, restroom supplies, first aid and safety products, fire extinguishers and testing, and safety training, Cintas helps customers get Ready for the Workday®. The company is also the creator of the Total Clean Program™ — a first-of-its-kind service that includes scheduled delivery of essential cleaning supplies, hygienically clean laundering, and sanitizing and disinfecting projects and services. Cintas was founded in 1968 by Richard T. Farmer, currently the Chairman Emeritus of the Board of Directors, when he left his family's industrial laundry business in order to develop uniform programs using an exclusive new fabric. In the early 1970's, Cintas acquired the family industrial laundry business. Over the years, Cintas developed additional products and services that complemented its core uniform business and broadened the scope of products and services available to its customers.

Cintas’ reportable operating segments are the Uniform Rental and Facility Services operating segment and the First Aid and Safety Services operating segment. The Uniform Rental and Facility Services reportable operating segment consists of the rental and servicing of uniforms and other garments, including flame resistant clothing, mats, mops and shop towels and other ancillary items. In addition to these rental items, restroom cleaning services and supplies and the sale of items from our catalogs to our customers on route are included within this reportable operating segment. The First Aid and Safety Services reportable operating segment consists of first aid and safety products and services. The remainder of Cintas’ business, which consists of the Fire Protection Services operating segment and the Uniform Direct Sale operating segment, is included in All Other.

The following table sets forth Cintas' total revenue and the revenue derived from each reportable operating segment and the remaining operating segments included in the All Other category for the fiscal years ended May 31:

(In thousands) 2021 2020 2019 Uniform Rental and Facility Services $ 5,689,632 $ 5,643,494 $ 5,552,430 First Aid and Safety Services 784,291 708,569 619,470 All Other 642,417 733,057 720,403 Total Revenue $ 7,116,340 $ 7,085,120 $ 6,892,303

Additional information regarding each reportable operating segment and All Other is also included in Note 14 entitled Operating Segment Information of "Notes to Consolidated Financial Statements."

In December 2019, a novel strain of coronavirus (COVID-19) was reported to have surfaced in Wuhan, China, and has since spread globally. In March 2020, the World Health Organization characterized COVID-19 as a pandemic. Efforts to contain the spread of COVID-19 intensified during our fiscal 2020 fourth quarter and have remained in effect throughout our fiscal 2021. Most states and municipalities within the U.S., as well as Canada, enacted temporary closures of businesses, issued quarantine orders and took other restrictive measures in response to the COVID-19 pandemic. Many of the business closures, quarantine orders and other restrictive measures remained in place through fiscal 2021. Within the U.S., our business was designated an essential business, which allowed us to continue to serve customers that remained open. During our fiscal 2021 fourth quarter, the roll out of vaccines, lower COVID-19 case counts and lifting of restrictions on businesses had a positive impact on our business.

We have operations throughout the U.S. and Canada and participate in a global supply chain. During most of fiscal 2021, the existence of the COVID-19 pandemic, the fear associated with the COVID-19 pandemic and the reactions of governments around the world in response to the COVID-19 pandemic to regulate the flow of labor and products

and impede the business of our customers, impacted our ability to conduct normal business operations, which had an adverse effect on our business. Many of Cintas' customers were also impacted by the COVID-19 pandemic, and we saw an impact on some customer's ability to pay timely. While there was minimal disruption to our supply chain, Cintas did increase inventory, primarily personal protective equipment and facility services inventory, in response to the customer needs and demand associated with the safety and cleanliness requirements of COVID-19. The increase in inventory resulted in additional inventory reserves during fiscal 2021 and could result in future inventory reserve increases if demand for personal protective equipment declines. See Note 1 entitled Significant Accounting Policies of "Notes to Consolidated Financial Statements" for additional detail on the additional reserve placed on inventory. The impact of the COVID-19 pandemic is fluid and continues to evolve, and therefore, we cannot predict the extent to which our business, consolidated results of operations, consolidated financial condition or liquidity will ultimately be impacted. For more information, see the sections entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and “Risk Factors” within this Annual Report on Form 10-K.

We provide our products and services to over one million businesses of all types, from small service and manufacturing companies to major corporations that employ thousands of people. This diversity in customer base results in no individual customer accounting for greater than one percent of Cintas' total revenue. As a result, the loss of one account would not have a significant financial impact on Cintas.

The primary markets served by all Cintas businesses are local in nature and highly fragmented. Cintas competes with national, regional and local providers, large national retailers and small local retailers as well as companies with a significant online presence and the level of competition varies at each of Cintas' local operations. Product, design, price, quality, service and convenience to the customer are the competitive elements in each of our businesses.

Within the Uniform Rental and Facility Services reportable operating segment, Cintas provides its products and services to customers via local delivery routes originating from rental processing plants and branches. Within the First Aid and Safety Services reportable operating segment and All Other, Cintas provides its products and services via its distribution network and local delivery routes or local representatives. At May 31, 2021, Cintas, in total, had approximately 11,000 local delivery routes, 460 operational facilities and 13 distribution centers.

Cintas is committed to sourcing responsibly. Cintas sources finished products from many outside suppliers. As mentioned on our website, www.cintas.com, each and every supplier must comply with a vendor code of conduct as a condition of doing business with Cintas. Cintas also conducts internal training to ensure that employees who have direct responsibility for supply chain management are knowledgeable and aware of issues and concerns surrounding our supply chain. In addition to sourcing from third-party suppliers, Cintas operates five manufacturing facilities that provide for standard uniform needs. Cintas purchases fabric, used in the manufacturing of its products, from several suppliers. Cintas is not aware of any circumstances that would hinder its ability to continue obtaining these materials.

Cintas is subject to a wide array of laws, government regulations, including environmental regulations, and standards in each domestic and foreign jurisdiction in which it operates. In addition to Cintas’s U.S. operations, which in fiscal 2021 generated over 90% of its consolidated net sales, Cintas also operates its business through wholly-owned subsidiaries in foreign jurisdictions, primarily in Canada. Compliance with these laws, government regulations, including environmental regulations, and standards requires the dedication of time and effort of employees as well as financial resources.

Compliance with environmental regulations and prioritizing our environmental sustainability efforts are important to us as a good corporate citizen. Our journey started in 1929 during the Great Depression when Doc and Amelia Farmer collected shop towels that had been disposed of by manufacturing facilities along the Ohio River.

Environmental spending related to water treatment and waste removal was approximately $19.0 million in fiscal 2021, approximately $20.0 million in fiscal 2020 and approximately $21.0 million in fiscal 2019. Capital expenditures to limit or monitor hazardous substances totaled approximately $1.0 million in fiscal 2021, approximately $3.0 million in fiscal 2020 and approximately $10.0 million in fiscal 2019.

In addition, health and safety regulations (including laws or regulations promulgated in response to the ongoing COVID-19 pandemic) have necessitated, and may continue to necessitate, increased operating costs or capital investments to promote a safe working environment. Cintas is also required to comply with increasingly complex and changing laws and regulations enacted to protect business and personal data in the U.S. and other jurisdictions regarding privacy, data protection and data security, including those related to the collection, storage, use, transmission and protection of personal information and other consumer, customer, vendor or employee data. With respect to the laws and regulations noted above, as well as other applicable laws and regulations, Cintas’s compliance programs may under certain circumstances involve material investments in the form of additional processes, training, personnel, information technology and capital. In fiscal 2021, compliance with the applicable laws, government regulations, including environmental regulations, and standards did not have a material effect on Cintas’s capital expenditures or consolidated results of operations. For a discussion of the risks associated with government regulations that may materially impact Cintas, please see “Item 1A: Risk Factors—Legal and Regulatory Risks.”

Cintas uses its corporate website, www.cintas.com, as a channel for routine distribution of important information, including news releases, analyst presentations and financial information. This year, Cintas produced an expanded Environmental, Social and Governance (ESG) Report to share our focus on making a positive impact through our key ESG priorities. This included work in areas of safety and health, energy and emissions, water usage, sustainable supply chain, and governance, ethics and integrity to support diversity and equality, assisting our employee-partners in need and giving back to the communities where we live and work. Particularly during unprecedented times and issues as a result of the COVID-19 pandemic, Cintas responded with improved policies, cleaning regimens and sanitizing products and services to help keep our employee-partners, and in turn, our customers, safer. We are also READY™ to help as many of our customers fully reopen their businesses.

Cintas Corporation (Cintas, Company, we, us or our), a Washington corporation, helps more than one million businesses of all types and sizes, primarily in the United States (U.S.), as well as Canada, Latin America, Europe and Asia, get READY™ to open their doors with confidence every day by providing a wide range of products and services that enhance our customers’ image and help keep their facilities and employees clean, safe and looking their best. With products and services including uniforms, mats, mops, restroom supplies, first aid and safety products, fire extinguishers and testing, and training and compliance courses, Cintas helps customers get Ready for the Workday®. Cintas was founded in 1968 by Richard T. Farmer, currently the Chairman Emeritus of the Board of Directors, when he left his family's industrial laundry business in order to develop uniform programs using an exclusive new fabric. In the early 1970's, Cintas acquired the family industrial laundry business. Over the years, Cintas developed additional products and services that complemented its core uniform business and broadened the scope of products and services available to its customers.

Cintas’ reportable operating segments are the Uniform Rental and Facility Services operating segment and the First Aid and Safety Services operating segment. The Uniform Rental and Facility Services reportable operating segment consists of the rental and servicing of uniforms and other garments, including flame resistant clothing, mats, mops and shop towels and other ancillary items. In addition to these rental items, restroom cleaning services and supplies, carpet and tile cleaning services and the sale of items from our catalogs to our customers on route are included within this reportable operating segment. The First Aid and Safety Services reportable operating segment consists of first aid and safety products and services. The remainder of Cintas’ business, which consists of the Fire Protection Services operating segment and the Uniform Direct Sale operating segment, is included in All Other.

In December 2019, a novel strain of coronavirus (COVID-19) was reported to have surfaced in Wuhan, China, and has since spread globally. In March 2020, the World Health Organization characterized COVID-19 as a pandemic. Through the first three quarters of fiscal 2020, the COVID-19 pandemic did not have a significant impact on our business. However, efforts to contain the spread of COVID-19 intensified during our fiscal 2020 fourth quarter. Most states and municipalities within the U.S. enacted temporary closures of businesses, issued quarantine orders and took other restrictive measures in response to the COVID-19 pandemic. Within the U.S., our business has been designated an essential business, which allows us to continue to serve customers that remain open.

We have operations throughout the U.S. and participate in a global supply chain. During the fourth quarter of fiscal 2020, the existence of the COVID-19 pandemic, the fear associated with the COVID-19 pandemic and the reactions of governments around the world in response to the COVID-19 pandemic to regulate the flow of labor and products and impede the business of our customers, impacted our ability to conduct normal business operations, which had an adverse effect on our business. If we need to close any of our facilities or a critical number of our employees become too ill to work, our business operations could be materially adversely affected in a rapid manner. Similarly, if our customers experience adverse business consequences due to the COVID-19 pandemic, including being required to shut down their operations, demand for our services and products could also be materially adversely affected in a rapid manner. The impact of the COVID-19 pandemic is fluid and continues to evolve, and therefore, we cannot predict the extent to which our business, results of operations, financial condition or liquidity will ultimately be impacted. For more information, see the sections entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and “Risk Factors” within this Annual Report on Form 10-K.

We provide our products and services to over one million businesses of all types, from small service and manufacturing companies to major corporations that employ thousands of people. This diversity in customer base results in no individual customer accounting for greater than one percent of Cintas' total revenue. As a result, the loss of one account would not have a significant financial impact on Cintas.

The following table sets forth Cintas' total revenue and the revenue derived from each reportable operating segment and the remaining operating segments included in the All Other category for the fiscal years ended May 31:

(In thousands) 2020 2019 2018 Uniform Rental and Facility Services $ 5,643,494 $ 5,552,430 $ 5,247,124 First Aid and Safety Services 708,569 619,470 564,706 All Other 733,057 720,403 664,802 Total Revenue $ 7,085,120 $ 6,892,303 $ 6,476,632

Additional information regarding each reportable operating segment and All Other is also included in Note 14 entitled Operating Segment Information of "Notes to Consolidated Financial Statements."

The primary markets served by all Cintas businesses are local in nature and highly fragmented. Cintas competes with national, regional and local providers, and the level of competition varies at each of Cintas' local operations. Product, design, price, quality, service and convenience to the customer are the competitive elements in each of our businesses.

Within the Uniform Rental and Facility Services reportable operating segment, Cintas provides its products and services to customers via local delivery routes originating from rental processing plants and branches. Within the First Aid and Safety Services reportable operating segment and All Other, Cintas provides its products and services via its distribution network and local delivery routes or local representatives.

Cintas purchases fabric, used in the manufacturing of its products, from several suppliers. Cintas is not aware of any circumstances that would hinder its ability to continue obtaining these materials.

Cintas is subject to various environmental laws and regulations, as are other companies in the uniform rental industry. While environmental compliance is not a material component of its costs, Cintas must incur capital expenditures and associated operating costs, primarily for water treatment and waste removal, on a regular basis. Environmental spending related to water treatment and waste removal was approximately $20 million in fiscal 2020, approximately $21 million in fiscal 2019 and approximately $20 million in fiscal 2018. Capital expenditures to limit or monitor hazardous substances totaled approximately $3 million in fiscal 2020, approximately $10 million in fiscal 2019 and approximately $2 million in fiscal 2018.

Cintas was founded in 1968 by Richard T. Farmer, currently the Chairman Emeritus of the Board of Directors, when he left his family's industrial laundry business in order to develop uniform programs using an exclusive new fabric. In the early 1970's, Cintas acquired the family industrial laundry business. Over the years, Cintas developed additional products and services that complemented its core uniform business and broadened the scope of products and services available to its customers.

U.S. Generally Accepted Accounting Principles (GAAP) requires companies to evaluate their reportable operating segments periodically and when certain events occur. As a result of a recent evaluation, effective June 1, 2015, Cintas realigned its organizational structure and updated its reportable operating segments in light of certain changes in its business including the acquisition of ZEE Medical Inc. (ZEE) in the first quarter of fiscal 2016. Cintas’ updated reportable operating segments are Uniform Rental and Facility Services and First Aid and Safety Services. The Uniform Rental and Facility Services reportable operating segment consists of the rental and servicing of uniforms and other garments including flame resistant clothing, mats, mops and shop towels and other ancillary items. In addition to these rental items, restroom cleaning services and supplies, carpet and tile cleaning services and the sale of items from our catalogs to our customers on route are included within this reportable operating segment. The First Aid and Safety Services reportable operating segment consists of first aid and safety products and services. The remainder of Cintas’ business, which consists primarily of Fire Protection Services and its Direct Sale business, is included in All Other.

Prior to June 1, 2015, Cintas classified its business into the following three reportable operating segments: the Rental Uniforms and Ancillary Products operating segment consisted of the rental and servicing of uniforms and other garments including flame resistant clothing, mats, mops and shop towels and other ancillary items. In addition to these rental items, restroom cleaning services and supplies and carpet and tile cleaning services were also provided within this operating segment. The Uniform Direct Sales operating segment consisted of the direct sale of uniforms and related items. The First Aid and Safety and Fire Protection Services operating segment consisted of first aid and safety products and services, and fire protection products and services.

In fiscal 2014, Cintas completed its partnership transaction with the shareholders of Shred-it International Inc. to combine Cintas' shredding business (Shredding) with the shredding business of Shred-it International Inc. (the Shredding Transaction). Pursuant to the Shredding Transaction, the newly formed partnership (the Shred-it Partnership) was owned 42% by Cintas and 58% by the shareholders of Shred-it International Inc. Cintas' investment in the Shred-it Partnership (Shred-it) and the results of Shredding are classified as discontinued operations for all periods presented as a result of selling the investment during fiscal 2016. During fiscal 2015, Cintas sold the storage business (Storage) and, as a result, its operations are also classified as discontinued operations for all periods presented. Shredding and Storage were previously included in the former Document Management Services reportable operating segment. In accordance with the applicable accounting guidance for the disposal of long-lived assets and discontinued operations, the results of Shredding and Storage have been excluded from both continuing operations and operating segment results for all periods presented. Please see Note 16 entitled Discontinued Operations of "Notes to Consolidated Financial Statements" for additional information.

We provide our products and services to over 900,000 businesses of all types — from small service and manufacturing companies to major corporations that employ thousands of people. This diversity in customer base results in no individual customer accounting for greater than one percent of Cintas' total revenue. As a result, the loss of one account would not have a significant financial impact on Cintas.

The following table sets forth Cintas' total revenue and the revenue derived from each reportable operating segment and All Other:

Fiscal Year Ended May 31, (in thousands) 2016 2015(1)(2) 2014(1)(2) Uniform Rental and Facility Services $ 3,777,801 $ 3,539,843 $ 3,304,635 First Aid and Safety Services 461,783 326,593 294,966 All Other 665,874 610,450 594,243 Total Revenue $ 4,905,458 $ 4,476,886 $ 4,193,844

(1) The figures for fiscal 2015 and 2014 presented reflect the change in classification of Shredding and Storage to discontinued operations within the Consolidated Statements of Income. See Note 16 entitled Discontinued Operations of "Notes to Consolidated Financial Statements."

(2) Cintas' reportable operating segments changed effective June 1, 2015. All prior fiscal periods have been recast to reflect that change.

Additional information regarding each reportable operating segment and All Other is also included in Note 14 entitled Operating Segment Information of "Notes to Consolidated Financial Statements."

The primary markets served by all Cintas businesses are local in nature and highly fragmented. Cintas competes with national, regional and local providers, and the level of competition varies at each of Cintas' local operations. Product, design, price, quality, service and convenience to the customer are the competitive elements in each of our businesses.

Within the Uniform Rental and Facility Services reportable operating segment, Cintas provides its products and services to customers via local delivery routes originating from rental processing plants and branches. Within the First Aid and Safety Services reportable operating segment and All Other, Cintas provides its products and services via its distribution network and local delivery routes or local representatives. In total, Cintas has approximately 9,000 local delivery routes, 377 operational facilities and eight distribution centers. At May 31, 2016, Cintas employed approximately 35,000 employees, of which approximately 200 were represented by labor unions.

Cintas sources finished products from many outside suppliers. In addition, Cintas operates five manufacturing facilities that provide for standard uniform needs. Cintas purchases fabric, used in its manufacturing process, from several suppliers. Cintas is not aware of any circumstances that would hinder its ability to continue obtaining these materials.

Cintas is subject to various environmental laws and regulations, as are other companies in the uniform rental industry. While environmental compliance is not a material component of its costs, Cintas must incur capital expenditures and associated operating costs, primarily for water treatment and waste removal, on a regular basis. Environmental spending related to water treatment and waste removal was approximately $13 million in fiscal 2016 and approximately $12 million in fiscal 2015. Capital expenditures to limit or monitor hazardous substances totaled approximately $3 million in fiscal 2016 and approximately $4 million in fiscal 2015. Cintas does not expect a material change in the cost of environmental compliance and is not aware of any material non-compliance with environmental laws.

Cintas Corporation ("Cintas," "Company," "we," "us" or "our"), a Washington corporation, provides highly specialized products and services to businesses of all types primarily throughout North America, as well as Latin America, Europe and Asia. Cintas' products and services are designed to enhance its customers' images and brand identification, as well as provide a safe and efficient workplace. Cintas was founded in 1968 by Richard T. Farmer, currently the Chairman Emeritus of the Board of Directors, when he left his family's industrial laundry business in order to develop uniform programs using an exclusive new fabric. In the early 1970's, Cintas acquired the family industrial laundry business. Over the years, Cintas developed additional products and services that complemented its core uniform business and broadened the scope of products and services available to its customers.

Effective August 31, 2014, Cintas classifies its businesses into three reportable operating segments ("operating segments") based on the types of products and services provided. The Rental Uniforms and Ancillary Products operating segment consists of the rental and servicing of uniforms and other garments including flame resistant clothing, mats, mops and shop towels and other ancillary items. In addition to these rental items, restroom cleaning services and supplies and carpet and tile cleaning services are also provided within this operating segment. The Uniform Direct Sales operating segment consists of the direct sale of uniforms and related items. The First Aid, Safety and Fire Protection Services operating segment consists of first aid, safety and fire protection products and services.

Previously, Cintas classified its businesses into four operating segments. The Document Management Services operating segment is no longer considered an operating segment. This operating segment consisted of document destruction services ("Shredding") and document imaging and retention services ("Storage"). On April 30, 2014, Cintas completed its partnership transaction with the shareholders of Shred-it International Inc. (Shred-it) to combine Cintas' Shredding with Shred-it's shredding business ("the Shredding Transaction"). Due to the deconsolidation of Shredding, fiscal 2015 results exclude the results of Shredding. Shredding remains reported in continuing operations for fiscal 2014 (through April 30, 2014 as previously discussed) and 2013. Based on the change in reportable operating segments, the results of Shredding for the year ended May 31, 2014 are presented within Corporate. Additionally, effective August 31, 2014, Storage is reported as a discontinued operation for all periods presented and has been excluded from continuing operations and from operating segment results for all periods presented. In the quarter ended November 30, 2014, Cintas sold Storage in a series of transactions ("Storage Transactions"). Please see Note 17 entitled Discontinued Operations of "Notes to Consolidated Financial Statements" for additional information.

On April 30, 2014, the Shredding Transaction was completed. Cintas Shredding represented approximately 76%, 80%, and 70% of Cintas' Document Management Services operating segment's assets, revenue, and income before income taxes, respectively, as of and for the quarter ended February 28, 2014. Under the agreement, Cintas and Shred-it each contributed its shredding business to a newly formed partnership owned 42% by Cintas and 58% by the shareholders of Shred-it ("the Shred-it Partnership"). In addition to its 42% ownership of the Shred-it Partnership, Cintas received $180.0 million in cash at the closing of the Shredding Transaction. Cintas' equity interest in the partnership is accounted for under the equity method of accounting as prescribed by U.S. generally accepted accounting principles ("GAAP").

We provide our products and services to over one million businesses of all types — from small service and manufacturing companies to major corporations that employ thousands of people. This diversity in customer base results in no individual customer accounting for greater than one percent of Cintas' total revenue. As a result, the loss of one account would not have a significant financial impact on Cintas.

The following table sets forth Cintas' total revenue and the revenue derived from each operating segment:

Fiscal Year Ended May 31, (in thousands) (1) 2015 2014 2013 Rental Uniforms and Ancillary Products $ 3,454,956 $ 3,223,930 $ 3,044,587 Uniform Direct Sales 453,653 455,485 461,328 First Aid, Safety and Fire Protection Services 568,277 514,429 460,592 Corporate (2) — 275,721 279,457 Total Revenue $ 4,476,886 $ 4,469,565 $ 4,245,964

(1) The figures for all years presented reflect the change in classification of Storage to discontinued operations within the Consolidated Statements of Income. See Note 17 entitled Discontinued Operations of "Notes to Consolidated Financial Statements."

(2) Corporate results for the fiscal years ended 2014 and 2013 include Shredding revenue. Fiscal year 2014 includes only eleven months of Shredding revenue as the Shredding Transaction closed on April 30, 2014.

Additional information regarding each operating segment is also included in Note 15 entitled Operating Segment Information of "Notes to Consolidated Financial Statements."

The primary markets served by all Cintas operating segments are local in nature and highly fragmented. Cintas competes with national, regional and local providers, and the level of competition varies at each of Cintas' local operations. Product, design, price, quality, service and convenience to the customer are the competitive elements in each of our operating segments.

Within the Rental Uniforms and Ancillary Products operating segment, Cintas provides its products and services to customers via local delivery routes originating from rental processing plants and branches. Within the Uniform Direct Sales and First Aid, Safety and Fire Protection Services operating segments, Cintas provides its products and services via its distribution network and local delivery routes or local representatives.

Cintas purchases fabric, used in its manufacturing process, from several suppliers. Cintas is not aware of any circumstances that would hinder its ability to continue obtaining these materials.

Cintas is subject to various environmental laws and regulations, as are other companies in the uniform rental industry. While environmental compliance is not a material component of its costs, Cintas must incur capital expenditures and associated operating costs, primarily for water treatment and waste removal, on a regular basis. Environmental spending related to water treatment and waste removal was approximately $20 million in fiscal 2012 and $18 million in fiscal 2011. Capital expenditures to limit or monitor hazardous substances were approximately $0.2 million in fiscal 2012 and approximately $2 million in fiscal 2011.

Cintas Corporation ("Cintas," "Company," "we," "us" or "our"), a Washington corporation, provides highly specialized products and services to businesses of all types primarily throughout North America, as well as Latin America, Europe and Asia. Cintas' products and services are designed to enhance its customers' images and brand identification, as well as provide a safe and efficient work place. Cintas was founded in 1968 by Richard T. Farmer, currently the Chairman Emeritus of the Board, when he left his family's industrial laundry business in order to develop uniform programs using an exclusive new fabric. In the early 1970's, Cintas acquired the family industrial laundry business. Over the years, Cintas developed additional products and services that complemented its core uniform business and broadened the scope of products and services available to its customers.

Cintas classifies its businesses into four operating segments based on the types of products and services provided. The Rental Uniforms and Ancillary Products operating segment consists of the rental and servicing of uniforms and other garments including flame resistant clothing, mats, mops and shop towels and other ancillary items. In addition to these rental items, restroom cleaning services and supplies and carpet and tile cleaning services are also provided within this operating segment. The Uniform Direct Sales operating segment consists of the direct sale of uniforms and related items and branded promotional products. The First Aid, Safety and Fire Protection Services operating segment consists of first aid, safety and fire protection products and services. The Document Management Services operating segment consists of document destruction, document imaging and document retention services.

We provide our products and services to over 900,000 businesses of all types — from small service and manufacturing companies to major corporations that employ thousands of people. This diversity in customer base results in no individual customer accounting for greater than one percent of Cintas' total revenue. As a result, the loss of one account would not have a significant financial impact on Cintas.

The following table sets forth Cintas' total revenue and the revenue derived from each operating segment:
