STE: 10-K Risk Factor Changes

Business continuity hazards and other risks include: explosions, fires, earthquakes, public health crises, extreme weather conditions, and other disasters, including those associated with climate change; disruptions of supply chains, or distribution for certain products or commodities; utility or other mechanical failures; unscheduled downtime; labor difficulties; inability to obtain or maintain any required licenses or permits; disruption of communications; data security, preservation and redundancy disruptions; inability to hire or retain key management or employees; and regulation of the safety, security or other aspects of our operations. The occurrence of these types of events has disrupted and may in the future disrupt or shut down operations, or otherwise adversely impact the production or profitability of a particular facility, or our operations as a whole. These events also might cause personal injury, loss of life, and other social and human effects (such as population dislocations), compliance costs and transition risks (such as regulatory or technology changes) or severe damage to or destruction of inventory, equipment, and other property, and for injuries occurring at our facilities or as a result of actions of our employees, result in liability claims against us. Although we maintain property and casualty insurance and liability and similar insurance of the types and in the amounts that we believe are appropriate for our business, there can be no assurance that we will be able to continue our insurance with acceptable terms, conditions or limits or that our insurance policies will provide adequate protection against all potential significant risks and liabilities.

Although we maintain property and casualty insurance and liability and similar insurance of the types and in the amounts that we believe are customary for our industries, our insurance coverages have limits and we are not fully insured against all potential hazards and risks incident to our business.

We have undertaken various activities to incorporate Lean concepts and practices to more efficiently operate our business, including in-sourcing. We continue to look for opportunities to in-source production that is currently provided by third parties. These activities may not produce the full efficiencies and cost reduction benefits that we expect, or efficiencies and benefits might be delayed. Implementing these activities can be complex and time-consuming, and anticipated initial costs may exceed expectations. The failure to realize such efficiencies and cost reduction benefits, or increases in the costs of doing business related to in-sourced production, could adversely impact our financial condition and results of operations.

The U.S. Tax Cuts and Jobs Act (the “TCJA”) was signed into law on December 22, 2017. Guidance continues to be issued clarifying the application of this legislation and changes have been proposed, and in many instances finalized, with respect to a number of income tax provisions (including foreign tax credit regulations) in the U.S. that could increase our total tax expense. In addition, beginning January 1, 2022, the limitation on deductibility of interest expense, which generally limits a deduction for interest expense to 30% of taxable income (subject to certain adjustments), must be determined by reducing taxable income by depreciation and amortization deductions, which may limit our ability to deduct interest expense in the future. We cannot predict the overall impact that the additional guidance and recent changes may have on our business. In addition, due to the expiration of many provisions of the TCJA at the end of 2025, the U.S. may experience a significant amount of changes to the tax rules impacting U.S. corporations. Such developments may further affect our income tax liability in the U.S. and, as a consequence, our effective tax rate. Furthermore, some non-U.S. jurisdictions have raised tax rates, and it is reasonable to expect that other global taxing authorities will be reviewing current legislation for potential modifications in reaction to the current provisions of the TCJA, potential future modifications or repeal of certain provisions of the TCJA, and other current economic conditions. In August 2022, the Inflation Reduction Act (the “IRA”) was signed into law. One of the provisions in the IRA added a corporate alternative minimum tax (“CAMT”) to the U.S. Internal Revenue Code of 1986, as amended (the “Code”), beginning for fiscal years 2023. We do not expect to be subject to the CAMT regime for fiscal years through 2025. However, if in the future we become subject to CAMT, then if our regular income tax liability in the U.S. is lower than the income tax liability calculated under the CAMT provisions, we will be subject to additional income taxes in the U.S. In addition, further changes in the tax laws of other jurisdictions will likely arise, including as a result of the base erosion and profit shifting ("BEPS") project undertaken by the Organization for Economic Cooperation and Development ("OECD"). The OECD, which represents a coalition of member countries, has issued recommendations that, in some cases, would make substantial changes to numerous long-standing tax positions and principles. Following the issuance of such recommendation, in December 2022, the European Union issued a directive to adopt Global Base Erosion laws (a/k/a GloBE or Pillar Two) in the EU member countries, in most cases beginning in fiscal year 2024. Most EU member countries and many non-EU member countries have already adopted local legislation based on GloBE Model Rules. Some of the countries that have not yet adopted GloBE are expected to do so in the near future. The GloBE rules could subject us to additional income taxes in the jurisdictions that adopted GloBE if our effective corporate tax rate in those jurisdictions (determined under the GloBE rules) is below 15%. Accordingly, the GloBE rules could increase tax uncertainty and adversely impact our provision for income taxes. In addition, the GloBE rules have certain transition period provisions that apply to certain intercompany transactions occurring between December 1, 2021 and the effective date of the GloBE rules in a given jurisdiction. These transition period provisions may have an adverse impact on our effective tax rate, and subject us to additional income tax, in some of the jurisdictions who adopt the GloBE rules. OECD continues to issue guidance under GloBE which could result in amendments and modifications of the local GloBE rules and further uncertainty of GloBE’s impact on our income tax expense.

We cannot predict the overall impact that the additional guidance and recent changes may have on our business. Some jurisdictions have raised tax rates, and it is reasonable to expect that other global taxing authorities will be reviewing current legislation for potential modifications in reaction to the implementation of the TCJA, current economic conditions, and COVID-19 response costs. In August 2022, President Biden signed the Inflation Reduction Act (the “IRA”) into law. One of the provisions in the IRA added a corporate alternative minimum tax (“CAMT”) to the U.S. Internal Revenue Code of 1986, as amended (the “Code”), beginning for fiscal years 2023. If income tax liability in the U.S. is lower than the income tax liability calculated under the CAMT provisions, we will be subject to additional income taxes in the United States. In addition, the IRS added excise tax on certain stock buybacks by publicly traded corporations. Even though the excise tax mostly impacts publicly traded companies organized in the U.S., under certain circumstances, the excise tax may be imposed on stock buybacks by a non-U.S. based publicly traded company like us. In addition, further changes in the tax laws of other jurisdictions will likely arise, including as a result of the base erosion and profit shifting ("BEPS") project undertaken by the Organization for Economic Cooperation and Development ("OECD"). The OECD, which represents a coalition of member countries, has issued recommendations that, in some cases, would make substantial changes to numerous long-standing tax positions and principles.

Many other non-EU member countries agreed to adopt GloBE between fiscal years 2024 and 2025. The GloBE rules, once implemented in the EU and other jurisdictions, could subject us to additional income taxes in those jurisdictions if our effective corporate tax rate in those jurisdictions (determined under the GloBE rules) is below 15%. Accordingly, the GloBE rules could increase tax uncertainty and adversely impact our 17 17 17 Table of Contents Table of Contents provision for income taxes. In addition, the GloBE rules have certain transition period provisions that apply to certain intercompany transactions occurring between December 1, 2021 and the effective date of the GloBE rules in a given jurisdiction. These transition period provisions may have an adverse impact on our effective tax rate, and subject us to additional income tax, in some of the jurisdictions who adopt the GloBE rules.

We purchase raw materials, fabricated and other components, and energy supplies from a variety of suppliers. Key raw materials include stainless steel, organic and inorganic chemicals, fuel, cobalt-60 and EO, and key components include plastic components, as well as various electronics including control boards and computer chips. The availability and prices of raw materials and energy supplies are subject to volatility and are influenced by worldwide economic conditions, speculative action, world supply and demand balances, inventory levels, availability of substitute materials, currency exchange rates, anticipated or perceived shortages, and other factors. In addition, administrations in the U.S. and other countries have recently announced plans to implement or increase tariffs, and it remains unclear what the ultimate outcome of these policy changes will be on our supply chains. Also, certain of our key materials and components have a limited number of suppliers, and some are single-sourced in certain regions of the world, such as cobalt-60 and EO, which are necessary for our AST operations. Given the limited number of suppliers for such materials, they may become subject to supply shortages or unavailability or increasing prices which could have a negative impact on our operations. Further, changes in regulatory requirements regarding the use of these materials might disrupt or cause shutdowns of portions of our AST operations or have other adverse consequences. Shortages in supply, increased regulatory or security requirements, or increases in the price of any of the raw materials, components and energy supplies used in our operations may adversely affect us.

Shortages in supply, increased regulatory or security requirements, or increases in the price of raw materials, components and energy supplies may adversely affect us. In response to the active Russia-Ukraine military conflict, we have stopped purchasing cobalt-60 from our Russian supplier. A long-term disruption in cobalt-60 sourced from Russia may negatively impact gamma processing capacity or increase costs in certain portions of our AST operations.

Some current or past operators of EO sterilization facilities, including us, have been the target of litigation on behalf of private plaintiffs alleging personal and other injuries as a result of exposure to emissions from such facilities and have experienced adverse judgments and entered into settlements. These developments, as well as other publicity related to EO litigation or regulatory activity, may increase the likelihood that we will continue to be subject to these claims or that we will be subject to more claims on behalf of similar plaintiffs in the future. Although we believe we have valid defenses to such claims, there can be no assurance that we will prevail on the merits, as the outcome of trials before juries and other aspects of litigation can be highly unpredictable, and, as a result, we have chosen to pursue a settlement process with respect to pending cases in Illinois. In March 2025, we agreed to pay up to approximately $48.2 million to resolve substantially all of the claims for personal injury against a subsidiary related to EO exposure that are pending in the Circuit Court of Cook County, Illinois. Please refer to Note 12 to our consolidated financial statements titled “Commitments and Contingencies” for further information. The financial impact of litigation, particularly mass tort action lawsuits, is also difficult to predict and a judgment entered or settlement reached in one case or group of cases is not necessarily representative of the outcome of other comparable cases. Regardless of the merits of the claims at issue or the ultimate outcome of cases, any future litigation related to our EO operations may be costly to defend, could result in an increase of our insurance premiums, reduction of limits and terms and could exhaust available insurance coverage. Defense of litigation may also result in diversion of management attention from other priorities, which could have a material adverse effect on our financial condition and results of operations.

Many governments, regulators, investors, employees, Customers and other stakeholders continue to be focused on corporate responsibility, including policies regarding climate change and greenhouse gas emissions. Other stakeholders, including governments and regulators, have expressed concerns about businesses' social commitments and sustainability goals. Responding to these considerations involves risks and uncertainties, requires significant investments and is impacted by factors that may be outside our control. In addition, some stakeholders may disagree with our priorities, statements and initiatives and the focus of stakeholders may change and evolve over time. Stakeholders also may have very different views on where corporate focus should be placed, including differing or conflicting views of regulators or elected officials in the various jurisdictions in which we operate. Any failure, or perceived failure, by us to achieve our goals, further our initiatives, adhere to our public statements, comply with federal, state or international laws and regulations or meet evolving and varied stakeholder 18 18 18 Table of Contents Table of Contents expectations and standards could result in advocacy group campaigns or legal and regulatory proceedings against us that could materially adversely affect our business, reputation, results of operations, financial condition and stock price. Many of our Customers are also committing to, and may become subject to legal or regulatory requirements with respect to, long-term targets to reduce greenhouse gas emissions within their supply chains and associated emissions reporting. If we are unable to support Customers in fulfilling these obligations or achieving reductions, we may lose revenue if our Customers find other suppliers who are better able to support such efforts. A failure, or perceived failure, to respond to expectations of all key stakeholders could cause harm to our business and reputation and have a negative impact on the market price of our ordinary shares. Further, organizations that provide information to investors on corporate governance and related matters have developed ratings processes for evaluating companies on social and environmental disclosures and commitments. Such ratings are used by some investors to inform their investment or voting decisions. Unfavorable ratings could lead to negative investor sentiment toward us and/or our industry, which could have a negative impact on our access to and costs of capital.

Many governments, regulators, investors, employees, Customers and other stakeholders are increasingly focused on ESG considerations relating to businesses, including climate change and greenhouse gas emissions, human capital and diversity, 19 19 19 Table of Contents Table of Contents equity and inclusion. We make statements about our ESG priorities and initiatives through information provided on our website, press statements and other communications. Responding to these ESG considerations and implementation of these laws, regulations and other initiatives involves risks and uncertainties, requires significant investments and is impacted by factors that may be outside our control. In addition, some stakeholders may disagree with our priorities and initiatives and the focus of stakeholders may change and evolve over time. Stakeholders also may have very different views on where ESG focus should be placed, including differing views of regulators in various jurisdictions in which we operate. Any failure, or perceived failure, by us to achieve our goals, further our initiatives, adhere to our public statements, comply with federal, state or international ESG laws and regulations or meet evolving and varied stakeholder expectations and standards could result in legal and regulatory proceedings against us that could materially adversely affect our business, reputation, results of operations, financial condition and stock price. As we continue to focus on developing our ESG practices, such practices may not meet the standards of all of our stakeholders and advocacy groups may campaign for further changes. Many of our Customers are also committing to, and may become subject to legal or regulatory requirements with respect to, long-term targets to reduce greenhouse gas emissions within their supply chains and associated emissions reporting. If we are unable to support Customers in fulfilling these obligations or achieving reductions, we may lose revenue if our Customers find other suppliers who are better able to support such efforts.

Such ratings are used by some investors to inform their investment or voting decisions. Unfavorable ESG ratings could lead to negative investor sentiment toward us and/or our industry, which could have a negative impact on our access to and costs of capital.

We operate in a highly competitive environment. Our businesses compete with other broad-line manufacturers, as well as many smaller businesses specializing in particular products or services, primarily on the basis of brand, design, quality, safety, ease of use, serviceability, price, product features, warranty, delivery, service, and technical support. We face increased competition from new infection prevention, sterile processing, contamination control, surgical support, cleaning consumables, 17 17 17 Table of Contents Table of Contents gastrointestinal endoscopy accessories, contract sterilization, and other products and services entering the market. Competitors and potential competitors also are attempting to develop alternate technologies and sterilizing agents, as well as disposable medical instruments and other devices designed to address the risk of contamination.

While we believe that we have developed appropriate measures to protect the health and well-being of our employees in the event of future health crises, there can be no assurances that our measures will be sufficient to protect our employees in our workplace or that they may not otherwise be exposed to an illness outside of our workplace. If a large or otherwise impactful number of our employees, including key employees, become ill, incapacitated or are otherwise unable or unwilling to continue working during any future health crises, our operations may be adversely impacted. Furthermore, restrictive measures implemented by us or governmental entities in response to a future pandemic or similar public health crisis could adversely impact our ability to hire and retain employees. Any failure to staff our operations resulting from an emergent public health crisis could adversely impact our financial condition and results of operations.

As supplier to Healthcare and Life Sciences Customers, we fell within a “critical infrastructure” sector, and were also considered an essential business and therefore were exempt under various stay-at -home/shelter-in-place orders associated with COVID-19. These exemptions, however, may not be available in another pandemic or similar health crisis and there can be no assurance that in such a crisis, we will be able to operate in the same manner. While we believe that we have developed appropriate measures to ensure the health and well-being of our employees for future health crises, there can be no assurances that our measures will be sufficient to protect our employees in our workplace or that they may not otherwise be exposed to an illness outside of our workplace. If a large or otherwise impactful number of our employees become ill, incapacitated or are otherwise unable or unwilling to continue working during the current or any future health crises, our operations may be adversely impacted.

Our continued success depends, in large part, on our ability to hire and retain highly qualified people, and if we are unable to do so, our business and operations may be impaired or disrupted. Labor market conditions are challenging, and the shortage of highly qualified people has led to increased competition. There is no assurance that we will be successful in attracting replacements to fill vacant positions, retaining successors to fill retirements or employees moving to new positions, or otherwise retaining qualified personnel. In addition, the increasing complexity of legal, regulatory and compliance matters have 20 20 20 Table of Contents Table of Contents created additional responsibilities for our management and other personnel and can create significant distraction or diversion of their attention, which could have a material adverse effect on our ability to attract and retain such personnel.

Our continued success depends, in large part, on our ability to hire and retain highly qualified people and if we are unable to do so, our business and operations may be impaired or disrupted. Labor market conditions, particularly in the United States, are challenging. The shortage of highly qualified people has led to increased competition, which has led to higher costs and other labor-related difficulties. There is no assurance that we will be successful in attracting or retaining replacements to fill vacant positions, successors to fill retirements or employees moving to new positions, or other highly qualified personnel. In addition, legal, regulatory or compliance matters create significant distraction or diversion of significant or unanticipated resources or attention that could have a material adverse effect on the responsibilities and retention of qualified employees. 21 21 21 Table of Contents Table of Contents

The success of our strategic business initiatives depend, in part, on our ability to realize the anticipated benefits and cost savings from such initiatives. These anticipated benefits and cost savings may not be realized fully or at all, may take longer to realize than expected, may require more non-recurring costs and expenditures to realize than expected or could have other 23 23 23 Table of Contents Table of Contents adverse effects that we do not currently foresee. Furthermore, assumptions that we have made with respect to acquisitions, dispositions or joint ventures, such as with respect to anticipated operating synergies or the costs associated with realizing such synergies, significant long-term cash flow generation, and the continuation of our investment grade credit profile, may not be realized. The processes involved with disposing of our businesses, entering into joint ventures or post-acquisition integration, as well as the implementation of other strategic initiatives, may result in the loss of key employees, the disruption of ongoing business, changes in strategy or inconsistencies in standards, controls, procedures, and policies. There could also be potential unknown liabilities and unforeseen expenses that were not discovered or previously expected. Although we conduct what we believe to be a prudent level of investigation regarding the operating and financial condition of the businesses, product or service lines, assets or technologies we purchase, divest or invest in, an unavoidable level of risk remains regarding their actual operating and financial condition, as well as their strategic fit. We may not be able to ascertain actual value or understand potential liabilities until or after we actually assume operational control of these businesses, product or service lines, assets or technologies.

The success of an acquisition depends, in part, on our ability to realize the anticipated benefits and cost savings from combining the businesses. The anticipated benefits and cost savings of an acquisition may not be realized fully or at all, may take longer to realize than expected, may require more non-recurring costs and expenditures to realize than expected or could have other adverse effects that we do not currently foresee. Assumptions that we have made with respect to acquisitions, such as with respect to anticipated operating synergies or the costs associated with realizing such synergies, significant long-term cash flow generation, and the continuation of our investment grade credit profile, may not be realized. The post-acquisition integration process may result in the loss of key employees, the disruption of ongoing business, changes in strategy or inconsistencies in standards, controls, procedures, and policies. There could be potential unknown liabilities and unforeseen expenses associated with acquisitions that were not discovered while performing due diligence. Although we conduct what we believe to be a prudent level of investigation regarding the operating and financial condition of the businesses, product or service lines, assets or technologies we purchase, an unavoidable level of risk remains regarding their actual operating and financial condition, as well as their strategic fit. We may not be able to ascertain actual value or understand potential liabilities until or after we actually assume operation control of these businesses, product or service lines, assets or technologies.

The long-term effects of climate change are difficult to assess and predict. The impacts may include social and human effects (such as population dislocations or harm to health and well-being), compliance costs and transition risks (such as regulatory or technology changes) and others. The effects could impair, for example, the availability and cost of energy (including utilities), and we may bear losses as a result. The regulations surrounding greenhouse gas emissions disclosures and sustainability reporting have also continued to evolve, with compliance requirements varying by jurisdiction. Governments, regulatory bodies and other stakeholders vary in their support of or opposition to sustainability and environmental matters in different jurisdictions in which we operate, which can lead to rapid shifts in reporting obligations and differing obligations across these jurisdictions. Both the standard setting and regulatory landscapes are also extremely complex and present significant compliance and communication challenges in light of these uncertain and varied approaches to greenhouse gas emissions disclosures and sustainability reporting. If our greenhouse gas emissions-related data, processes or reporting are incomplete or inaccurate, or if we fail to comply with relevant reporting frameworks from existing or newly emerging regulations, we may incur monetary penalties and reputational harm, investor demand for our securities could decrease, or we could become subject to litigation or governmental investigations, any of which may have a material adverse effect on our financial condition and results of operations. For example, on January 5, 2023, the CSRD became effective. The CSRD expands the number of companies required to publicly report ESG-related information, defines the ESG-related information that companies are required to disclose in accordance with ESRS and imposes additional assurance obligations with respect to such disclosures. While CSRD rules are prescriptive for the types of data to be reported, the methodology for quantifying and qualifying such data are still developing and uncertain and may impose increased costs on us related to complying with our reporting obligations and increase risks of non-compliance with ESRS and the CSRD. In addition, there is currently uncertainty surrounding the requirements to publish ESG-related information under the CSRD and the content requirements of such report under the ESRS. On February 26, 2025, the European Commission proposed an “Omnibus” reform law that would delay application of the CSRD by two years (so-called “stop the clock”) and that proposes reducing the number of reporting requirements under the ESRS. On April 17, 2025, the "stop the clock" delay became effective at the EU level, and EU member states have until December 31, 2025 to transpose the delay into national law. However, the balance of the changes to the CSRD proposed as part of the Omnibus package need to progress through the European Union's legislative process and require political approval. Responses from the European Union member countries have been varied, and there is uncertainty as to when and how the CSRD may be changed in light of these proposals; however, Irish officials have expressed support for the proposed changes and further pledged to amend existing Irish legislation to clarify and reduce the scope of companies covered. These changes, and any other new or pending legal or regulatory matters, may result in the expenditure of additional resources or costs to comply with such requirements, which could affect our financial condition, results of operations or cash flows.

The long-term effects of climate change are difficult to assess and predict. The impacts may include physical risks (such as rising sea levels or frequency and severity of extreme weather conditions), social and human effects (such as population dislocations or harm to health and well-being), compliance costs and transition risks (such as regulatory or technology changes) and other adverse effects. The effects could impair, for example, the availability and cost of certain products, commodities and energy (including utilities), which in turn may impact our ability to procure goods or services required for the operation of our business at the quantities and levels we require. We may bear losses as a result of, for example, physical damage to or destruction of our facilities (such as distribution or fulfillment centers), loss or spoilage of inventory, and business interruption due to weather events that may be attributable to climate change, which could materially and adversely affect our business operations, financial position or results of operation. There has also been an increased focus from regulators and stakeholders on greenhouse gas emissions and climate-related risks. Both the standard setting and regulatory landscapes are extremely complex and present significant compliance challenges. Many different organizations are promulgating reporting standards and rules that focus on addressing greenhouse gas emissions and climate-related topics. In March 2024, the SEC adopted its final rule, “The Enhancement and Standardization of Climate-Related Disclosures for Investors,” which sets forth certain prescriptive rules that would significantly increase our reporting obligations and cost of compliance. Subsequently, the SEC voluntarily stayed the implementation of such rules pending the completion of judicial review by the Court of Appeals for the Eighth Circuit, and it is unclear whether the final rules will be implemented in whole, in part or at all. On January 5, 2023, the European Commission’s Corporate Sustainability Reporting Directive (“CSRD”) became effective. The CSRD expands the number of companies required to publicly report ESG-related information, defines the ESG-related information that companies are required to disclose in accordance with European Sustainability Reporting Standards (“ESRS”) and imposes additional assurance obligations with respect to such disclosures. While CSRD rules are prescriptive for the types of data to be reported, the standards to quantify and qualify such data are still developing and uncertain, and may impose increased costs on us related to complying with our reporting obligations and increase risks of non-compliance with ESRS and the CSRD.

Ongoing geopolitical instability has negatively impacted, and could in the future negatively impact, the global and U.S. economies, including by causing supply chain disruptions, rising inflation, volatility in capital markets and foreign currency exchange rates, rising interest rates, reduced consumer and Customer demand, economic slowdowns and recessions and heightened cybersecurity risks. The extent to which such geopolitical instability adversely affects our business, financial condition and results of operations, as well as our liquidity and capital profile, may depend on future developments that are highly uncertain and unpredictable. If geopolitical instability materially affects us, it may also have the effect of heightening other risks related to our business. The potential impacts of such geopolitical instability include supply chain and logistics disruptions, financial impacts including volatility in foreign exchange and interest rates, increased inflationary pressure on raw materials and energy, reduced consumer and Customer demand, economic slowdowns and recessions and other risks, including an elevated risk of cybersecurity threats and the potential for new or further sanctions, tariffs or changes to international trade policy. For instance, the U.S. and other countries have announced changes, and planned changes, to international trade policy, including increasing tariffs on imports, and potentially renegotiating or terminating existing trade agreements. The international trade environment is highly dynamic, and such changes, and retaliatory responses thereto, continue to evolve. Tariffs, trade restrictions and other changes to international trade policies may result in increased production costs and product pricing, supply chain disruptions, limited access to end markets, lower profitability, increasing inability of consumers and Customers to pay, reduced consumer and Customer demand, economic slowdowns and recessions and uncertainty related to planning long-term investments and strategies, and may have other competitive effects, each of which could have a material adverse effect on our business. We may also need to make material changes to our global production footprint and workforce, which could require significant capital expenditures and could result in asset impairments and other charges, including restructuring charges, any of which could be material. The duration and scope of all such changes that have been and will ultimately be implemented are not known at this time, and as such, any resulting impacts on our business are uncertain. 13 13 13 Table of Contents Table of Contents

Ongoing geopolitical instability, including as a result of the Russia-Ukraine and Israel-Hamas military conflicts, has negatively impacted, and could in the future negatively impact, the global and U.S. economies, including by causing supply chain disruptions, rising energy costs, volatility in capital markets and foreign currency exchange rates, rising interest rates and heightened cybersecurity risks. The extent to which such geopolitical instability adversely affects our business, financial condition and results of operations, as well as our liquidity and capital profile, will depend on future developments, which are highly uncertain and unpredictable. If geopolitical instability adversely affects us, it may also have the effect of heightening other risks related to our business. In response to the military conflict between Russia and Ukraine that began in February 2022, the United States and other North Atlantic Treaty Organization member states, as well as non-member states, announced targeted economic sanctions on Russia. The long-term impact on our business resulting from the disruption of trade in the region caused by the conflict and associated sanctions and boycotts is uncertain at this time due to the fluid nature of the ongoing military conflict and response.
