• Unrecognized gross tax benefits of $7.4 million at December 31, 2025, could potentially affect future income tax provisions.

Risks

• Macroeconomic factors, including labor shortages, supply chain disruptions, inflation, higher interest rates, and recession risks, could adversely affect demand in the aerospace, packaging, automotive, and ground transportation industries.
• Operating in a highly competitive industry with larger competitors may lead to reduced demand, pricing pressure, or an inability to differentiate products effectively.
• Reductions in demand for products may be more severe and occur prior to reductions in demand for customers' products due to long supply chains and inventory destocking cycles.
• Customers may reduce their demand for aluminum products in favor of alternative materials such as titanium, composites, carbon fiber, steel, glass, paper, or plastic, particularly in aerospace, packaging, and automotive applications.
• Government relaxation or delay of fuel efficiency or emissions standards, or a protracted period of low oil prices, could reduce demand for new, more efficient aircraft and automobiles.
• The commercial aerospace industry is cyclical and subject to disruption from factors like declines in global travel, airline profitability, terrorism, pandemics, regulatory actions, and safety concerns.
• Reductions in defense spending for aerospace and non-aerospace military applications could adversely affect demand for the company's products.
• Downturns in the automotive and ground transportation industries, driven by consumer spending, economic strength, or model mix shifts, could adversely affect demand for Automotive Extrusions and GE Products.
• Dependence on a core group of significant customers (top five accounted for approximately 56% of 2025 net sales) poses a risk if any of these relationships deteriorate or business is lost.
• Inability to pass through fluctuations of certain costs (energy, raw materials, operating supplies, freight) to customers, coupled with ongoing pricing pressure, could adversely affect financial results.
• The industry is sensitive to foreign economic, regulatory, and political factors, including tariffs, trade disputes, import/export controls, currency restrictions, and geopolitical instability.
• Difficulties in the launch or production ramp-up of new products could lead to manufacturing disruptions, delays, increased costs, and reputational harm.
• Unplanned events such as explosions, fires, natural disasters, equipment failures, labor disruptions, transportation interruptions, public utilities interruptions, and cyber incidents could interrupt production operations, especially at key facilities like Trentwood and Warrick.
• Challenges to intellectual property rights, including competitors developing similar technologies or misappropriation, could adversely affect the company's competitive position.
• Reliance on third-party suppliers and service providers for critical inputs, transportation, logistics, and operational support exposes the company to disruptions if these parties fail to perform.
• Inability to successfully implement productivity enhancement and cost reduction initiatives may prevent the company from offsetting competitive price pressure.
• Investment and expansion projects may not be completed as scheduled, exceed cost expectations, or fail to deliver the anticipated capacity and other benefits.
• Reliance on Alcoa Corporation for certain essential resources at the Warrick facility poses a risk if Alcoa fails to provide these resources, potentially leading to substantial costs or operational shutdowns.
• Business could be adversely affected by the pricing and availability of primary aluminum, including negative impacts from Metal Price Lag during periods of declining prices.
• Business could be adversely affected by the pricing and availability of recycled scrap aluminum, particularly if scrap discounts relative to primary aluminum decline.
• Business could be adversely affected by the pricing and availability of alloying metals due to limited suppliers, government regulations, or supply chain disruptions.
• Volatility in aluminum prices can impact borrowing availability and liquidity by reducing the market value of inventory and accounts receivable, which serve as collateral.
• Hedging programs may be adversely impacted by market fluctuations, supply chain disruptions, and geopolitical activity, leading to ineffectiveness or margin calls.
• Covenants and events of default in debt instruments could limit the company's ability to undertake certain transactions and adversely affect liquidity.
• Servicing debt requires a significant amount of cash, and insufficient cash flow could force the company to reduce investments, dispose of assets, or refinance debt.
• Failure to maintain satisfactory labor relations, especially with approximately 65% of employees represented by unions and 26% of those contracts expiring within one year, could lead to strikes or unfavorable terms.
• Participation in multiemployer union pension plans carries risks, including potential withdrawal liabilities and increased contributions if other participating employers fail to meet their obligations.
• Adverse capital market conditions could result in reductions in the fair value of pension plan assets and increase liabilities related to such plans.
• The USW's director nomination rights (40% of the Board until 2030) may lead to influence that does not align with the interests of all stockholders or other stakeholders.
• Environmental compliance, cleanup costs, and damage claims, including ongoing remediation activities at Trentwood and Newark, may decrease cash flow and adversely affect the business.
• Governmental regulation relating to greenhouse gas emissions may subject the company to significant new costs and restrictions on operations, impacting energy and raw material prices and supply chains.
• Expectations relating to sustainability considerations expose the company to potential liabilities, increased costs, reporting requirements, and reputational harm, including 'greenwashing' or consumer protection claims.
• Risks related to information technology systems and third-party service providers, including cybersecurity breaches, cyberattacks, and data theft, could disrupt operations and harm reputation.
• The future declaration and payment of dividends and stock repurchases are at the discretion of the Board and subject to financial performance and contractual restrictions.
• Delaware law and the company's governing documents may impede or discourage a takeover, potentially affecting the value of common stock.
• Other general risks for publicly traded U.S. manufacturing companies include attracting and retaining key personnel, skills shortages, regulatory capital requirements, compliance with various laws, acquisition integration challenges, intellectual property protection, impacts of artificial intelligence, concentrated ownership influence, legal proceedings, and taxation by multiple jurisdictions.

Future Outlook

The company anticipates continued long-term growth in demand for Aero/HS products driven by air travel and fuel efficiency, and further growth in packaging demand underpinned by sustainability trends and the shift from plastic to aluminum. Fuel efficiency standards and consumer preference for lightweight vehicles are expected to drive demand for aluminum extruded components in automotive applications. Total capital spending in 2026 is projected to be between $120.0 million and $130.0 million, focused on capacity expansion, operational sustainability, product quality, and efficiency. Management believes current liquidity and operational cash flows will be sufficient to meet short-term and long-term obligations for at least the next 12 months. The company expects to pay a partial withdrawal liability of approximately $4.6 million in 2027 related to a facility exit and estimates a net mark-to-market gain of $5.2 million in AOCI will be reclassified into Net income within the next 12 months.
