ITEM 1 – Business

General Development of Business

Founded in 1870 by George H. Tennant, Tennant Company ("the Company, we, us, or our"), headquartered in Eden Prairie, Minnesota, is a world leader in designing, manufacturing and marketing of solutions that help create a cleaner, safer and healthier world. Tennant was incorporated as a Minnesota corporation in 1909 and began as a one-man woodworking business, eventually evolving into a successful wood flooring and wood products company, and finally into a manufacturer of floor cleaning equipment. Throughout its history, the Company has remained focused on advancing its industry by aggressively pursuing new technologies and creating a culture that celebrates innovation.

Today, the Company has 11 global manufacturing locations and operates in three geographic areas including the Americas, Europe, Middle East and Africa ("EMEA") and Asia Pacific ("APAC"). We aggregate our operating segments into one reportable segment that consists of the design, manufacture, sale and servicing of products used primarily in the maintenance of nonresidential surfaces.

Our commitment to innovation and excellence extends across every aspect of our business—from product development and customer service to manufacturing and marketing. We prioritize delivering high-performance solutions that minimize waste, lower costs, enhance safety, and advance sustainability objectives. By dedicating resources to research, development and engineering, we continuously refine existing products and introduce new ones that align with evolving market demands.

Over the past century, we have expanded our brand portfolio, diversified our product offerings, and advanced our technologies through innovation and strategic acquisitions. This disciplined approach to growth ensures that each acquisition complements our existing capabilities and adds value by enhancing our product range or improving technological expertise.

Principal Products, Markets and Distribution

The Company offers products and solutions consisting of manual and autonomous mechanized cleaning equipment for both industrial and commercial use, detergent-free and other sustainable cleaning technologies, aftermarket parts and consumables, equipment maintenance and repair services, and business solutions such as financing, rental and leasing programs, and machine-to-machine asset management solutions. The Company is committed to developing cleaning technologies which increase cleaning productivity. We have strong brand presence in the global markets we serve, offering both premium and mid-tier products for each region to meet customer needs.

The Company's products are used in many types of environments including: retail establishments, distribution centers, factories and warehouses, public venues such as arenas and stadiums, office buildings, schools and universities, hospitals and clinics, and more. The Company markets its offerings under the following brands: Tennant®, Nobles®, Alfa Uma Empresa Tennant™, IPC, Gaomei and Rongen brands as well as private-label brands. The Company has a portfolio of differentiated technology solutions that includes an expanding portfolio of robotic cleaning equipment, IRIS® as an asset management solution, ec-H2O NanoClean® as a detergent-free cleaning solution, and ReadySpace® as a rapid-drying carpet cleaning technology. The Company's more than 40,000 customers include contract cleaners to whom organizations outsource facilities maintenance, as well as businesses that perform facilities maintenance themselves. The Company reaches these customers through the industry's largest direct sales and service organization and through a strong and well-supported network of authorized distributors worldwide.

The Company has an extensive global field service network. We sell products directly in 21 countries and through distributors in more than 100 countries.

Raw Materials and Component Parts

Steel, metal alloys and resin are the primary raw materials used to manufacture our mechanized cleaning equipment. We purchase various component parts, electronics and services used in production and product development processes from third parties.

Operations and input costs are influenced by global macroeconomic conditions, including trade policies, tariffs on certain imported materials, interest rate levels, and regional supply-demand dynamics. While supply chain conditions have generally stabilized compared to prior periods, input costs remain subject to variability driven by tariff regimes, competitive market conditions, and regulatory requirements in certain jurisdictions.

The Company seeks to mitigate these risks through regional manufacturing and sourcing strategies, diversified supplier relationships, longer-term supply arrangements, and ongoing engineering and platform design initiatives intended to increase sourcing flexibility and supply chain resilience.

Intellectual Property

The Company owns a broad range of intellectual property rights in both the United States and a number of foreign countries. Our patents, proprietary technologies and trade secrets, customer relationships, licenses, trademarks, trade names and brand names in the aggregate constitute a valuable asset, but we do not regard our business as being materially dependent upon any single item or category of intellectual property. We take appropriate measures to protect our intellectual property to the extent such intellectual property can be protected.

Research and Development

Research and development expenses include scientific research costs such as salaries, prototypes, shop supplies, testing, technical information technology and administrative expenditures as well as an allocation of corporate costs. We conduct research and development activities to develop new products and to enhance the functionality, effectiveness, ease of use and reliability of our existing products. We believe that our research and development efforts have been, and continue to be, key drivers of our success in the marketplace, and we continue to explore new technologies and methodologies that help improve the efficiency and sustainability of our products.

Seasonality

Although the Company’s business is not seasonal in the traditional sense, the percentage of revenues in each quarter typically ranges from 22% to 28% of the total year. The first quarter tends to be at the low end of the range reflecting customers’ initial slow ramp up of capital purchases and the Company’s efforts to close out orders at the end of each year. The second and fourth quarters tend to be toward the high end of the range and the third quarter is typically in the middle of the range.

Major Customers

The Company sells a wide range of products to a diversified base of customers around the world and has no material concentration of credit risk or significant payment terms extended to customers.

Competition

Public industry data concerning global market share is limited; however, based on a review of validated third-party sources and sponsored market studies, the Company believes it is a leading global manufacturer of floor maintenance and cleaning equipment. The competitive landscape includes large multinational manufacturers operating across most geographic markets, as well as numerous regional and local participants that vary by country, vertical market, product category, channel, and degree of automation and technological capability, including the availability of autonomous and robotic cleaning solutions. Customer purchasing decisions are influenced by product performance, innovation, connectivity, automation, total cost of ownership, and the breadth of sales, service, and distribution support. Within this environment, the Company primarily

We prioritize the health and safety of all employees. We operate under our established safety programs and employ an experienced team of health and safety specialists as well as a crisis management team to provide support to employees globally. All locations work diligently to meet and/or exceed regulatory standards applicable to each site. Tennant employees are empowered to stop work when a potential hazard is identified. Each site maintains public and confidential ways for employees to report safety concerns to ensure employees feel free to report their concerns.

Talent

We believe attraction, development, engagement, and retention of a diverse group of employees is key to achieving our organizational objectives. We focus on creating a high-performance culture, including our annual performance management process for all employees which aligns with our employee and leadership competency frameworks.

To support employee development, we deploy several resources and development tools for all employees. We also provide leaders access to on-demand eLearnings and targeted live training sessions. In addition, we engage in annual talent and succession planning conversations to help identify, develop, and deploy talent to achieve our objectives and address talent risks.
