Parker Hannifin Corporation: 10-K Risk Factor Changes

We expect to continue our strategy of identifying and acquiring businesses with complementary products and services, and entering into joint ventures, which we believe will enhance our operations and profitability. However, there can be no assurance that we will be able to continue to find suitable businesses to purchase or joint venture opportunities, or that we will be able to acquire such businesses or enter into such joint ventures on acceptable terms. Furthermore, there are no assurances that we will be able to avoid acquiring or assuming unexpected liabilities. If we are unable to avoid these risks, our results of operations and financial condition could be materially adversely affected. 14 14 14 Table of Contents Table of Contents In addition, we may not be able to integrate successfully any businesses that we purchase into our existing business and it is possible that any acquired businesses or joint ventures may not be profitable. For example, we have devoted significant management attention and resources to integrating the business and operations of Meggitt. We may encounter, or have encountered, the following difficulties during the integration process: •the consequences of a change in tax treatment, including the cost of integration and compliance and the possibility that the full benefits anticipated to result from the acquisitions may not be realized; •delays in the integration of management teams, strategies, operations, products, and services; •differences in business backgrounds, corporate cultures, and management philosophies that may delay successful integration; •the ability to retain key employees; •the ability to create and enforce uniform standards, controls, procedures, policies, and information systems; •challenges of integrating complex systems, technologies, networks, and other assets of the acquired companies in a manner that minimizes any adverse impact or disruptions to customers, suppliers, employees, and other constituencies; and •unknown liabilities and unforeseen increased expenses or delays associated with the integration beyond current estimates. The successful integration of new businesses and the success of joint ventures also depend on our ability to manage these new businesses and cut excess costs. If we are unable to avoid these risks, our results of operations and financial condition could be materially adversely affected.

Our operations necessitate the use and handling of hazardous materials and, as a result, subject us to various U.S. federal, state and local laws and regulations, as well as non-U.S. laws, designed to protect the environment and to regulate the discharge of materials into the environment. These laws impose penalties, fines and other sanctions for non-compliance and liability for response costs, property damages and personal injury resulting from past and current spills, disposals or other releases of, or the exposure to, hazardous materials. Among other laws, we are subject to the U.S. federal "Superfund" law, under which we have been designated as a "potentially responsible party" and may be liable for clean-up costs associated with various waste sites, some of which are on the United States Environmental Protection Agency’s Superfund priority list. We could incur substantial costs as a result of non-compliance with or liability for cleanup or other costs or damages under environmental laws, including the "Superfund" law. In addition, increased worldwide focus on climate change issues has led to legislative and regulatory efforts to limit greenhouse gas emissions. Increased regulation of greenhouse gas emissions and other climate change concerns could subject us to additional costs and restrictions, including increased energy and raw material costs. We are not able to predict how such regulations would affect our business, operations or financial results, but increased regulation could have a material adverse effect on our business, operations and financial condition. Further, climate change resulting from increased concentrations of carbon dioxide and other greenhouse gases in the atmosphere could present risks to our operations. Extreme weather events linked to climate change, including hurricanes, flooding, wildfires, high heat and water scarcity, among others, create physical risks to our operating locations and supply chains. Although we are working towards and intend to meet our goal of making our own operations carbon neutral by 2040, we may be required to expend significant resources to do so, which could increase our operational costs. Further, there can be no assurance of the extent to which any of our climate-related goals will be achieved, if at all, including on the timeline expected by customers or investors, or that any future investments we make in furtherance of achieving our goals will meet customer expectations and needs, investor expectations or market standards regarding sustainability, including reducing greenhouse gas emissions. Any failure, or perceived failure, by us to achieve our climate-related goals, further our initiatives, adhere to our public statements, comply with federal, state or international climate-related laws and regulations or meet evolving and varied customer and investor expectations and standards could result in legal and regulatory proceedings against us or could cause our customers to find other suppliers, each of which could adversely affect our reputation, the market price of our common shares, our results of operations, our financial condition or our cash flows.

Our net sales derived from customers outside the United States were approximately 37 percent in 2023, 39 percent in 2022 and 40 percent in 2021. In addition, many of our manufacturing operations and suppliers are located outside the United States. The Company expects net sales from non-U.S. markets to continue to represent a significant portion of its total net sales. Our non-U.S. operations are subject to risks in addition to those facing our domestic operations, including: •fluctuations in currency exchange rates and/or changes in monetary policy; •limitations on ownership and on repatriation of earnings; •transportation delays and other supply chain disruptions; •political, social and economic instability and disruptions, including armed conflicts such as the current conflict between Russia and Ukraine; •government embargoes, sanctions or trade restrictions; •the imposition of duties and tariffs and other trade barriers; •import and export controls; •labor unrest and current and changing regulatory environments; •public health crises, including pandemics; •the potential for nationalization of enterprises; •difficulties in staffing and managing multi-national operations; •limitations on our ability to enforce legal rights and remedies; •potentially adverse tax consequences; and •difficulties in implementing restructuring actions on a timely basis. 11 11 11 Table of Contents Table of Contents For example, the global nature of our business and our operations exposes us to political, economic, and other conditions in foreign countries and regions, including geopolitical risks such as the current conflict between Russia and Ukraine. The broader consequences of this conflict, which may include further sanctions, embargoes, regional instability, and geopolitical shifts; potential retaliatory action by the Russian government against companies, including possible nationalization of foreign businesses in Russia; increased tensions between the United States and countries in which we operate; and the extent of the conflict’s effect on our business and results of operations as well as the global economy, cannot be predicted. To the extent the current conflict between Russia and Ukraine adversely affects our business, it may also have the effect of heightening many other risks, any of which could materially and adversely affect our business and results of operations. Such risks include, but are not limited to, adverse effects on macroeconomic conditions, including inflation, particularly with regard to raw material, transportation and labor price fluctuations; disruptions to our information technology environment, including through cyberattack, ransom attack, or cyber-intrusion; adverse changes in international trade policies and relations; disruptions in global supply chains; and our exposure to foreign currency exchange rate changes. If we are unable to successfully manage the risks associated with expanding our global business or adequately manage operational fluctuations internationally, the risks could have a material adverse effect on our business, results of operations or financial condition.

Our recent acquisitions have greatly expanded the size and complexity of our business. Our future success depends, in part, on the ability to manage this expanded business, which may pose or has posed substantial challenges for management, including challenges related to the management and monitoring of the expanded global operations and new manufacturing processes and products, and the associated costs and complexity. There can be no assurance of successful management of these matters or that we will realize the expected benefits of the acquisitions.
