Table of Contents reduced operations and production rates, and/or took cost-cutting actions, including, but not limited to, General Electric Company, Raytheon Technologies Corporation and The Boeing Company, which represented approximately 11%, 9% and 8%, respectively, of our third-party sales in 2020. Due to the foregoing factors and other cost-cutting measures, we are experiencing, and expect to continue experiencing, lower demand and volume for our products, customer requests for potential payment deferrals, pricing concessions or other contract modifications, and delays in deliveries and the achievement of other billing milestones. COVID-19 may also limit the ability of our counterparties generally to perform their obligations to us, including, but not limited to, our customers’ ability to make timely payments to us. These trends may lead to charges, impairments and other adverse financial impacts over time, as noted above, as we have historically depended upon the strength of these industries, particularly the commercial aerospace industry. In addition, the ongoing COVID-19 pandemic may negatively impact customer contract negotiations, including the ability to negotiate acceptable terms in contract renewal negotiations and our ability to obtain new customers. Similarly, our suppliers may not have the materials, capacity, or capability to manufacture our products according to our schedule and specifications. To date, we have not experienced significant disruption to our supply chain. If our suppliers’ operations were to be impacted, we may need to seek alternate suppliers, which may be more expensive, may not be available or may result in delays in shipments to us and subsequently to our customers, each of which would adversely affect our business, results of operations, financial condition and/or cash flows. The duration of the current disruptions to our customers and to our supply chain, and related financial impact to us, cannot be estimated at this time. Should such disruption continue for an extended period of time, the impact will have a material adverse effect on our business, results of operations, financial condition and/or cash flows. Ultimately, the demand for our products is, in turn, driven by demand for transportation and for people to travel within and between various countries. Should the COVID-19 pandemic cause a long- term deterioration in demand for transportation or travel due to fear or anxiety related to health concerns, governmental restriction, economic hardships, or increased use of electronic communication technologies embraced during the COVID-19 related shutdowns, the effects on our business may extend well beyond the current COVID-19 health crisis and immediate related governmental actions. • Market risks : The current financial market dynamics and volatility pose heightened risks to our liquidity. For example, dramatically lower interest rates and lower expected asset valuations and returns can materially impact the calculation of long-term liabilities such as our pension. In addition, extreme volatility in financial markets has had and may continue to have adverse impacts on other asset valuations such as the value of the investment portfolios supporting our pension. Our long-term liabilities are sensitive to numerous factors and assumptions that can move in offsetting directions and should be considered as of the time of a relevant measurement event. • Liquidity and credit risks : We currently have the ability to borrow up to $1.0 billion under our Five-Year Revolving Credit Agreement (the “Credit Agreement”), which was amended in June 2020. A prolonged period of generating lower financial results and cash from operations could adversely affect our financial condition, including in respect of satisfying both required and voluntary pension funding requirements, could result in potential increases in net debt or reductions in EBITDA, and could otherwise negatively affect our ability to achieve our strategic objectives. If the foregoing or other factors negatively impact our ability to comply with the financial covenant in the Credit Agreement, our ability to draw under the Credit Agreement would be adversely affected. There can also be no assurance that we will not face credit rating downgrades as a result of weaker than anticipated performance of our business or other factors, including overall market conditions. Rating downgrades could further adversely affect our cost of funds and related margins, liquidity, competitive position and access to capital markets, and a significant downgrade could have an adverse commercial impact on our business. Conditions in the financial and credit markets may also limit the availability of funding or increase the cost of funding (including for receivables securitization or supply chain finance programs used to finance working capital) or our ability to refinance certain of our indebtedness, which could adversely affect our business, financial position, results of operations and/or cash flows. Although the U.S. federal and other governments have announced a number of funding programs to support businesses, our ability or willingness to access funding under such programs may be limited by regulations or other guidance, including eligibility criteria, or by further change or uncertainty related to the terms of these programs. The COVID-19 pandemic may also exacerbate other risks disclosed herein, including, but not limited to, risks related to global economic conditions, competition, loss of customers, costs of supplies, manufacturing difficulties and disruptions, investment returns, our credit profile, our credit ratings and interest rates. We expect that the longer the period of disruption from COVID-19 continues, the more material the adverse impact will be on our business operations, financial performance, results of operations and/or cash flows. In addition, the COVID-19 pandemic may also affect our operating and financial results in a manner that is not presently known to us or that we currently do not expect to present significant risks to our business, results of operations, financial conditions and/or cash flows. The markets for Howmet’s products are highly cyclical and are influenced by a number of factors, including global economic conditions. 12
