- Risks Related to Our Ability to Continue as a Going Concern
- We have identified conditions and events that raise substantial doubt about our ability to continue as a going concern. Doubts regarding our ability to continue as a going concern could materially adversely affect our business, results of operations and financial condition, and share price.
- Unexpected payment obligations or unanticipated liabilities may create liquidity challenges and further challenge our ability to continue as a going concern.
- We may be unsuccessful in discussions with our financial stakeholders, including for the potential restructuring of our indebtedness or may be unable to obtain necessary waivers or amendments.
- Deterioration of our credit profile could limit our access to commercial credit.
- Risks Related to Delisting of our Ordinary Shares
- We have received notice of delisting procedures from the New York Stock Exchange (“NYSE”) and trading in our shares has been suspended, and trading may continue to be restricted with no trading market readily available.
- Risks Related to Our Indebtedness
- Our current and future level of indebtedness of our subsidiaries could adversely affect our financial condition.
- The terms of our subsidiaries’ indebtedness may restrict our current and future operations, particularly our ability to respond to change or to take certain actions.
- Risks Related to Our Operations
- We are subject to risks associated with our strategy to transform to a specialty materials and sustainable solutions provider.
The other 31 risks
- We may be unable to achieve cost savings and other benefits from our restructuring activities and cost reduction initiatives.
- Volatility in the cost of raw materials, disruption in the supply of raw materials, may adversely affect our financial condition and results of operations or cause our financial results to differ materially from our forecasts.
- Increased energy costs, shipping costs and supply constraints, including as a result of ongoing global conflicts, could adversely impact our results of operations.
- Chemical manufacturing is inherently hazardous and production at our manufacturing facilities could be disrupted for a variety of reasons. Disruptions could expose us to significant losses or liabilities.
- If we are not able to continue the technological innovation and successful commercial introduction of new products, our customers may turn to other producers to meet their requirements.
- If we are unable to execute on our capital projects, growth or maintenance projects within their expected budget and timelines, or if the market conditions assumed in our projections deteriorate, our business, financial condition, results of operations and cash flows could be materially and adversely affected.
- Risks Related to Acquisitions and Dispositions
- We may not be successful in the proposed divestiture of our interest in Americas Styrenics.
- Joint ventures may not operate according to their business plans if we or our partners fail to fulfill our or their obligations, or differences in views among our joint venture partners result in delayed decisions, which may adversely affect our results of operations and may force us to dedicate additional resources to these joint ventures.
- We may fail to realize the anticipated benefits of acquisitions or such benefits may take longer to realize than expected, and we may encounter difficulty integrating these businesses into our operations. We may also be required to incur impairment and other charges, which would adversely affect our operating results.
- We may engage in other future strategic disposition or acquisitions of certain assets and/or businesses that could affect our business, results of operations, financial condition and liquidity.
- Risks Related to Regulation and Compliance
- We are subject to customs, international trade, export control, and antitrust laws that could require us to modify our current business practices and incur increased costs.
- Global trade conflicts and the imposition of tariffs may have a material adverse impact on our business and results of operations.
- We could be subject to changes in the global and local tax regulatory environments in the jurisdictions in which we operate, which could adversely impact our results of operations.
- Regulatory and statutory changes, including those related to climate change and sustainability, applicable to our raw materials and products or our customers’ products, or changes to consumer preferences or public perception, could require material expenditures, changes in our operations and could adversely affect our financial condition and results of operations.
- Compliance with extensive and evolving environmental, health and safety laws may require substantial expenditures.
- We may be subject to losses due to liabilities or lawsuits related to contaminated land we own or operate or arising out of environmental damage or personal injuries associated with exposure to chemicals or the release of chemicals.
- Risks Related to Litigation
- We are party to certain legal proceedings, and may be subject to additional litigation, arbitration or legal proceedings in the future.
- Risks Related to Our Relationship with Dow
- Dow provides significant operating and other services, and certain raw materials used in the production of our products, under agreements that are important to our business. The failure of Dow to perform its obligations, or the termination of these agreements, could adversely affect our operations.
- We are party to certain license agreements with Dow relating to intellectual property that is essential to our business. Because of this relationship, we may have limited ability to expand our use of certain intellectual property beyond the field of the license or to police infringement that may be harmful to our business.
- Risks Related to Our Intellectual Property
- Our business relies on intellectual property and other proprietary information and our failure to adequately protect or effectively enforce our rights, or our ability to successfully license our intellectual property, could harm our competitive advantages with respect to the manufacturing of some of our products.
- Our products may infringe the intellectual property rights of others, which may cause us to incur unexpected costs or prevent us from selling our products.
- Risks Related to Data Security
- Cybersecurity incidents including data breaches could compromise confidential information related to our business or the private information of our employees, vendors, and customers, or could negatively impact our operations, which could adversely affect our business and our reputation.
- Risks Related to our Information Systems
- The suspension of a new enterprise resource planning (“ERP”) system implementation could cause disruption to our operations.
- Risks Related to Our Ordinary Shares
- Irish law differs from the laws in effect in the U.S. and may afford less protection to holders of our securities than companies formed in the U.S.
- Provisions of our articles of association and Irish law could delay or prevent a takeover of us by a third party.
- Any attempts to take us over will be subject to Irish Takeover Rules and subject to review by the Irish Takeover Panel.
- As an Irish public limited company, certain capital structure decisions regarding the Company will require the approval of shareholders, which may limit the Company’s flexibility to manage its capital structure.
- General Risks
- Conditions in the global economy and capital markets may adversely affect our results of operations, financial condition and cash flows.
- As a global business, we are exposed to local business risks in different countries, which could have a material adverse effect on our financial condition or results of operations.
- We face competitive risks related to excess supply capacity.
- Fluctuations in currency exchange rates may significantly impact our results of operations and may significantly affect the comparability of our results between financial periods.
Legal proceedings
From time to time, we may be subject to various legal claims and proceedings incidental to the normal conduct of business, relating to such matters as product liability, antitrust, competition, waste disposal practices, release of chemicals into the environment, current and former employees, and other matters that may arise in the ordinary course of our business. Regardless of the outcome, legal proceedings can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.
