In addition, Howmet has operating activities in numerous countries and regions outside the United States and Europe, including Canada, Mexico, China and Japan. Governmental policies, laws and regulations, and other economic factors, including inflation and fluctuations in foreign currency exchange rates and interest rates, affect the results of operations in countries with such operating activities.

Background

The Arconic Inc. Separation Transaction

Howmet Aerospace Inc. is the new name for Arconic Inc., following Arconic Inc.’s separation of its businesses on April 1, 2020 (the “Arconic Inc. Separation Transaction”) into two independent, publicly traded companies – Howmet Aerospace Inc. and Arconic Corporation. Following this separation, Howmet retains the Engine Products, Fastening Systems, Engineered

Table of Contents

Structures, and Forged Wheels businesses; and Arconic Corporation holds the Rolled Products, Aluminum Extrusions, and Building and Construction Systems businesses. The Company trades under the symbol “HWM” on the New York Stock Exchange, and Arconic Corporation trades under the symbol “ARNC” on the New York Stock Exchange.

The Arconic Inc. Separation Transaction was effected by a distribution of all outstanding shares of Arconic Corporation common stock to the Company’s stockholders (the “Distribution of Arconic”). The Company’s stockholders of record as of the close of business on March 19, 2020 (the “2020 Record Date”) received one share of Arconic Corporation common stock for every four shares of the Company’s common stock held as of the 2020 Record Date. The Company did not issue fractional shares of Arconic Corporation common stock in the Distribution of Arconic. Instead, each stockholder otherwise entitled to receive a fractional share of Arconic Corporation common stock received cash in lieu of fractional shares.

In connection with the Arconic Inc. Separation Transaction, Howmet and Arconic Corporation entered into several agreements that govern the relationship of the parties following the separation, including the following: Separation and Distribution Agreement, Tax Matters Agreement, Employee Matters Agreement, certain Patent, Know-How and Trade Secret License Agreements, certain Trademark License Agreements, Raw Material Supply Agreements, Second Supplemental Tax and Project Certificate and Agreement, and Lease and Property Management Agreement.

The 2017 Reincorporation of Howmet (then known as Arconic Inc.)

On December 31, 2017 (the “Effective Date”), Arconic Inc., a Pennsylvania corporation (“Arconic Pennsylvania”), effected the change of Arconic Pennsylvania’s jurisdiction of incorporation from Pennsylvania to Delaware (the “Reincorporation”) by merging (the “Reincorporation Merger”) with a direct wholly owned Delaware subsidiary, Arconic Inc. (in this section, “Arconic Delaware” or, following the Reincorporation, the “Company”), pursuant to an Agreement and Plan of Merger, dated as of October 12, 2017, by and between Arconic Pennsylvania and Arconic Delaware. Arconic Pennsylvania shareholders approved the Reincorporation Merger to effect the Reincorporation at a Special Meeting of Shareholders held on November 30, 2017. As a result of the Reincorporation, (i) Arconic Pennsylvania ceased to exist, (ii) Arconic Delaware automatically inherited the reporting obligations of Arconic Pennsylvania under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and (iii) Arconic Delaware is deemed to be the successor issuer to Arconic Pennsylvania.

The common stock, par value $1.00 per share, of Arconic Pennsylvania (the “Arconic Pennsylvania Common Stock”) was listed for trading on the New York Stock Exchange and traded under the symbol “ARNC.” As of the Effective Date, this symbol, without interruption, represented shares of common stock, par value $1.00 per share, of Arconic Delaware (the “Arconic Delaware Common Stock”). There was no change in the Exchange Act File Number assigned by the SEC as a result of the Reincorporation.

As of the Effective Date, the rights of the Company’s stockholders began to be governed by the General Corporation Law of the State of Delaware, the Certificate of Incorporation of Arconic Delaware and the Bylaws of Arconic Delaware.

Other than the change in corporate domicile, the Reincorporation did not result in any change in the business, physical location, management, financial condition or number of authorized shares of the Company, nor did it result in any change in location of its current employees, including management. On the Effective Date, (i) the directors and officers of Arconic Pennsylvania prior to the Reincorporation continued as the directors and officers of Arconic Delaware after the Reincorporation, (ii) each outstanding share of Arconic Pennsylvania Common Stock was automatically converted into one share of Arconic Delaware Common Stock, (iii) each outstanding share of Serial Preferred Stock, par value $100 per share, of Arconic Pennsylvania was automatically converted into one share of Serial Preferred Stock, par value $100 per share, of Arconic Delaware and (iv) all of Arconic Pennsylvania’s employee benefit and compensation plans immediately prior to the Reincorporation were continued by Arconic Delaware, and each outstanding equity award and notional share unit relating to shares of Arconic Pennsylvania Common Stock was converted into an equity award or notional share unit, as applicable, relating to an equivalent number of shares of Arconic Delaware Common Stock on the same terms and subject to the same conditions. Beginning on the Effective Date, each certificate representing Arconic Pennsylvania Common Stock or Arconic Pennsylvania Preferred Stock was deemed for all corporate purposes to evidence ownership of Arconic Delaware Common Stock or Arconic Delaware Preferred Stock, as applicable. The Company’s stockholders may, but are not required to, exchange their stock certificates as a result of the Reincorporation.

The Alcoa Inc. Separation Transaction

On November 1, 2016, Alcoa Inc. completed the separation of its business into two independent, publicly traded companies (the “Alcoa Inc. Separation Transaction”) – Arconic Inc. (the new name for Alcoa Inc. and which, through the transactions described above, later became Howmet Aerospace Inc.) and Alcoa Corporation. Following the Alcoa Inc. Separation Transaction, the Company retained the Global Rolled Products (other than the rolling mill at the Warrick, Indiana operations and the 25.1% ownership stake in the Ma’aden Rolling Company), the Engineered Products and Solutions and the Transportation and Construction Solutions segments. Alcoa Corporation comprised the Alumina and Primary Metals segments,

Table of Contents

the rolling mill at the Warrick, Indiana operations, and the 25.1% stake in the Ma’aden Rolling Company in Saudi Arabia previously held by the Company.

The Alcoa Inc. Separation Transaction was effected by a pro rata distribution of 80.1% of the outstanding shares of Alcoa Corporation common stock to the Company’s shareholders (the “Distribution of Alcoa”). The Company’s shareholders of record as of the close of business on October 20, 2016 (the “2016 Record Date”) received one share of Alcoa Corporation common stock for every three shares of the Company’s common stock held as of the 2016 Record Date. The Company did not issue fractional shares of Alcoa Corporation common stock in the Distribution of Alcoa. Instead, each shareholder otherwise entitled to receive a fractional share of Alcoa Corporation common stock received cash in lieu of fractional shares.

The Company distributed 146,159,428 shares of common stock of Alcoa Corporation in the Distribution of Alcoa and retained 36,311,767 shares, or approximately 19.9%, of the common stock of Alcoa Corporation immediately following the Distribution of Alcoa. During 2017, the Company disposed all of its retained interest in Alcoa Corporation.

As a result of the Distribution of Alcoa, Alcoa Corporation became an independent public company trading under the symbol “AA” on the New York Stock Exchange, and the Company traded under the symbol “ARNC” on the New York Stock Exchange.

On October 31, 2016, in connection with the Alcoa Inc. Separation Transaction, Arconic Inc. entered into several agreements with Alcoa Corporation or its subsidiaries that govern the relationship of the parties following the Distribution of Alcoa, including the following: Separation and Distribution Agreement, Tax Matters Agreement, Employee Matters Agreement, and certain Patent, Know-How, Trade Secret License and Trademark License Agreements.

Description of the Business

The Company produces products that are used primarily in the aerospace (commercial and defense), commercial transportation, and industrial and other end markets. Such products include fastening systems (titanium, steel, and nickel superalloys), seamless rolled rings (mostly nickel superalloys); investment castings (nickel superalloys, titanium, and aluminum), including airfoils and structural parts; forged jet engine components (e.g., jet engine disks); machined and forged aircraft parts (titanium and aluminum); and forged aluminum commercial vehicle wheels, all of which are sold directly to customers and/or through distributors.

Aerospace (Commercial and Defense) End Market. Howmet’s largest end market is aerospace, which represented approximately 69% of the Company’s revenue in 2020. The Company produces a range of high performance multi-materials, highly engineered products, and vertically integrated machined solutions for aero engines and airframe structures, ranging from investment castings, advanced coatings, seamless rings, forgings, titanium extrusions, and titanium mill products, to fasteners that hold aircraft together. Wingtip to wingtip, nose to tail, Howmet can produce more than 90% of all structural and rotating aero engine components. Modernization of the commercial and defense platforms is driven by an array of challenging performance requirements. With its precision engineering, materials science expertise and advanced manufacturing processes, Howmet aims to help its customers achieve greater fuel economies, reduced emissions, passenger comfort and maintenance efficiencies.

Generally, raw materials are purchased from third-party suppliers under competitively priced supply contracts or bidding arrangements. The Company believes that the raw materials necessary to its business are and will continue to be available.

Patents, Trade Secrets and Trademarks

The Company believes that its domestic and international patent, trade secret and trademark assets provide it with a significant competitive advantage. The Company’s rights under its patents, as well as the products made and sold under them, are important to the Company as a whole and, to varying degrees, important to each business segment. The patents owned by Howmet generally concern particular products, manufacturing equipment or techniques. Howmet’s business as a whole is not, however, materially dependent on any single patent, trade secret or trademark. As a result of product development and technological advancement, the Company continues to pursue patent protection in jurisdictions throughout the world. As of the end of 2020, the Company’s worldwide patent portfolio consists of approximately 959 granted patents and 183 pending patent applications.

The Company also has a significant number of trade secrets, mostly regarding manufacturing processes and material compositions that give many of its businesses important advantages in their markets. The Company continues to strive to improve those processes and generate new material compositions that provide additional benefits. With respect to domestic and international registered trademarks, the Company has many that have significant recognition within the markets that are served. Examples include the name Howmet® metal castings, Huck® fasteners, and Dura-Bright® wheels with easy-clean surface treatments. A significant trademark filing campaign for the names “Howmet” and “Howmet Aerospace” along with its “H” logo was initiated in 2019, in support of the corporate launch of Howmet Aerospace Inc. As of the end of 2020, the Company’s worldwide trademark portfolio consists of approximately 1,372 registered trademarks and 329 pending trademark applications. The Company’s rights under its trademarks are important to the Company as a whole and, to varying degrees, important to each business segment.

Competitive Conditions

The Company’s segments - Engine Products, Fastening Systems, Engineered Structures and Forged Wheels - are subject to substantial and intense competition in the markets they serve. Although Howmet believes its advanced technology, manufacturing processes and experience provide advantages to Howmet’s customers, such as high quality and superior mechanical properties that meet the Company’s customers’ most stringent requirements, many of the products Howmet makes can be produced by competitors using similar types of manufacturing processes as well as alternative forms of manufacturing. Despite intense competition, Howmet continues as a market leader in most of its principal markets. Several factors, including Howmet’s technological expertise, state-of-the-art capabilities, engaged employees and long-standing customer relationships, enable the Company to maintain its competitive position.

Principal competitors include Berkshire Hathaway Inc., through its 2016 acquisition of Precision Castparts Corporation and subsidiaries, for titanium and titanium-based alloys, precision forgings, seamless rolled rings, investment castings and aerospace fasteners; VSMPO (Russia) for titanium and titanium-based alloys and precision forgings; the High-Performance Materials & Components segment of Allegheny Technologies, Inc. for titanium and titanium-based alloys, precision forgings, and investment castings; Lisi Aerospace (France) for aerospace fasteners; and Aubert & Duval (part of Eramet Group in France) for precision forgings. Other competitors include Doncasters Group Ltd. (UK) and Consolidated Precision Products Corp. (owned by Warburg Pincus and Berkshire Partners) for investment castings; Weber Metals (part of Otto Fuchs) for precision forgings; and Forgital and Frisa (Mexico) for seamless rings.

Forged Wheels competes against aluminum and steel wheel suppliers in the commercial transportation industry under the product brand name Alcoa® Wheels for the major regions that it serves (Americas, Europe, Japan, China, and Australia). Its larger aluminum wheel competitors are Accuride Corporation, Speedline (member of the Ronal Group), Nippon Steel Corporation, Dicastal, Alux, and Wheels India Limited. In recent years, Forged Wheels has seen an increase in the number of

Table of Contents

aluminum wheel suppliers (both forged and cast aluminum wheels) from China, Taiwan, India and South Korea attempting to penetrate the global commercial transportation market.

Several of Howmet’s largest customers have captive superalloy furnaces for producing airfoil investment castings for their own use. Many other companies around the world also produce superalloy investment castings, and some of these companies currently compete with Howmet in the aerospace and other markets, while others are capable of competing with the Company should they choose to do so.

International competition in the investment castings, fasteners, rings and forgings markets may also increase in the future as a result of strategic alliances among engine original equipment manufacturers (“OEMs”), aero-structure prime contractors, and overseas companies, especially in developing markets, particularly where “offset” or “local content” requirements create purchase obligations with respect to products manufactured in or directed to a particular country.

Environmental Matters

Information relating to environmental matters is included in Note V to the Consolidated Financial Statements under the caption “Environmental Matters.” Capital expenditures for new or expanded facilities for environmental control for 2021 and 2022 are estimated to be less than $5 million per year.

Human Capital

To recruit, attract, develop and retain world-class talent, the Company has created a culture that embraces diversity, drives inclusion, and empowers and engages our employees.

Training and Development

The Company offers an integrated approach, enabling our employees to own their development and create rewarding careers that draw on their aptitudes and support their ambitions. We provide learning and development opportunities and equip our managers to provide ongoing coaching and feedback, so employees maximize their performance and potential, delivering success for Howmet.

Diversity, Equity and Inclusion

Events in 2020, particularly in the United States, underscored the importance and power of diversity, equity and inclusion ("DEI"). Howmet’s inclusive, respectful and values-based company culture fosters inclusive work environments that leverage the diversity of backgrounds, experience and thought within our organization. The Company partners with key external organizations that focus on DEI, including the Human Rights Campaign, the National Hispanic Corporate Council and Diversity Best Practices, to review and continuously improve our DEI initiatives. We continue to seek additional partners to further eliminate discrimination and implicit bias from the Company’s policies and processes.

During 2020, we renewed our commitment to supporting our six employee resource groups ("ERGs") – Howmet African Heritage Network, Howmet Hispanic Network, Howmet Next Generation Network, Howmet Pride Network, Howmet Veterans Network and Howmet Women’s Network. The ERGs provide workplace networks for employees who have shared characteristics, special interests or life experiences. They offer a conduit to professional development, strengthen business impact internally and externally, and promote commitments to a diverse workplace. During 2020, the ERGs provided a positive way for the Company to direct dedicated company resources toward employee education, community building and social impact initiatives.

The Company also provided diversity awareness training on implicit bias and added inclusion to our leadership competency development in 2020.

Health and Safety

Howmet’s strong health and safety culture empowers our employees and contractors to take personal responsibility for their actions and the safety of their coworkers. This culture is supported by internal policies, standards, rules and procedures that clearly articulate our stringent requirements for working safely in all of our facilities worldwide. The Company embeds annual health and safety goals and objectives into its operating plans to progress against our ultimate goal of zero incidents. We prioritize our risk management processes toward the prevention of fatality and serious injury potential to focus on the hazards that have the potential for life-altering outcomes.

COVID-19 represented the biggest health challenge in the history of our Company, impacting our employees, suppliers and customers. This adverse situation became a unifying moment, as our employees worked tirelessly to establish internal and external programs and protocols to protect our people and processes, which were deemed essential for the aerospace, defense and transportation industries. Through our pandemic deployment system, the Company readied our plants around the world with a comprehensive toolbox based on risk. We structured our location pandemic programs around entry screening, self- assessment of symptoms, hygiene, masks, social distancing and robust implementation of tracing and quarantine protocols.

Table of Contents

Special pandemic-related policies for leave and alternative schedules were put in place to incentivize staying at home when sick. In addition, for employees who could meet their work commitments remotely, we provided resources and equipment to enable them to work from home. Access to mental health and resilience support was communicated and made available through our employee assistance partners.

Employees

Total worldwide employment at the end of 2020 was approximately 19,700 employees in 24 countries. Many, but less than 50%, of these employees are represented by labor unions. The Company believes that relations with its employees and any applicable union representatives generally are good.

There are nine collective bargaining agreements in the United States with varying expiration dates. In the United States, the largest collective bargaining agreement is the agreement between Howmet and the United Autoworkers ("UAW") at our Whitehall, Michigan location. The Whitehall UAW agreement covers approximately 1,000 employees; the current agreement expires on March 31, 2023. In addition to the employees covered by the Whitehall UAW agreement, approximately 1,600 other employees in the United States are also represented by labor unions.

On a regional basis, collective bargaining agreements with varying expiration dates cover employees in Europe, North America, South America, and Asia.

Item 1A. Risk Factors.

Howmet’s business, financial condition and results of operations may be impacted by a number of factors. In addition to the factors discussed elsewhere in this report, the following risks and uncertainties could materially harm the Company’s business, financial condition or results of operations, including causing its actual results to differ materially from those projected in any forward-looking statements. The following list of risk factors is not all-inclusive or necessarily in order of importance. Additional risks and uncertainties not presently known to Howmet or that Howmet currently deems immaterial also may materially adversely affect the Company in future periods.

Risks Related to Our Business and Operations

Our business, results of operations, financial condition and/or cash flows have been and could continue to be materially adversely affected by the effects of the COVID-19 pandemic.

Any outbreaks of contagious diseases, public health epidemics or pandemics and other adverse public health developments in countries where we, our employees, customers and suppliers operate could have a material and adverse effect on our business, results of operations, financial condition and/or cash flows. Specifically, the COVID-19 pandemic affecting the global community, including the United States, Europe and South America, is adversely impacting our operations, and the nature and extent of the impact over time is highly uncertain and beyond our control. The extent to which COVID-19 further affects our operations over time will depend on future developments, which are highly uncertain, including the duration of the pandemic, the continued severity of the virus, resurgences and emergence of variants of the virus, the efficacy and availability of vaccines, and the extent of actions that may be taken to contain its impact. These actions include, but are not limited to, declarations of states of emergency, business closures, manufacturing restrictions and a prolonged period of travel, commercial and/or other similar restrictions and limitations, many of which have been implemented across much of the globe and all of which have negatively affected our business. The longer the duration, the greater the impact on our business and the more heightened the risk of a continuing material adverse effect on our business, results of operations, financial conditions and/or cash flows, as well as on our business strategies and initiatives. We continue to monitor guidelines proposed by federal, state and local, as well as foreign, governments with respect to measures for continued operation, which may change over time depending on public health, safety and other considerations. We are continuing to focus on the safety and protection of our workforce by continuing to implement additional safety protocols in light of COVID-19.

As a result of COVID-19 and the measures designed to contain its spread, our global sales, including to customers in the aerospace and commercial transportation industries that are impacted by COVID-19, have been and are expected to continue to be negatively impacted due to the disruption in demand, which has had and over time could continue to have a material adverse effect on our business, results of operations, financial condition and/or cash flows. The COVID-19 pandemic has subjected our operations, financial performance and financial condition to a number of risks, including, but not limited to, those discussed below:

•Business and operations risks: We continue to monitor the evolving situation relating to COVID-19 to determine whether we will need to significantly modify our business practices or take actions as may be required by government authorities or that we determine are in the best interests of our employees, customers, partners, suppliers and shareholders. We have had a number of smaller manufacturing locations that have experienced periods of shutdowns. Future shutdowns will be dependent on facts and circumstances as they unfold, including based on the restrictions and limitations noted above. Additional shutdowns, while not required by governmental authorities, may be necessary to match our production to the reduced demand of our customers. In addition, due to the foregoing factors and potential further disruptions, we may be unable to perform fully on our contracts and our costs may increase. We may also face challenges in restoring our production levels if and when COVID-19 abates, including as a result of government-imposed or other limitations that prevent the return of all or a portion of our workforce, continue to disrupt demand and/or limit the capabilities of our suppliers. As a result of COVID-19 and its potential impact on the aerospace industry, the possibility exists that a sustained impact to our operations, financial results and market capitalization may require material impairments of our assets, including, but not limited to, goodwill, intangible assets, long-lived assets, and right-of-use assets. While we have already implemented plans to reduce costs, including certain headcount reductions, reductions in certain cash outflows, suspension of our common stock dividend and reductions in the levels of our capital expenditures, the longer-term impact of the COVID-19 pandemic is uncertain, but could continue to have a material adverse effect on our business, results of operations, financial condition and/or cash flows.

•Customer and supplier risks: We have limited visibility into future demand due to the disruptions resulting from COVID-19. The sharp decrease in air travel resulting from the COVID-19 pandemic and the measures that governments and private organizations worldwide have implemented in an attempt to contain its spread is adversely affecting, and will likely continue to adversely affect, airlines and airframers and their respective demand for our customers’ products and services. Aircraft manufacturers are reducing production rates due to fewer expected aircraft deliveries and, as a result, demand for products in the OEM market has significantly decreased. Several of our aerospace and commercial transportation customers temporarily suspended operations at certain production sites,

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.

Table of Contents

Howmet is subject to cyclical fluctuations in global economic conditions and lightweight metals end-use markets. Howmet sells many products to industries that are cyclical, such as the aerospace and commercial transportation industries, and the demand for its products is sensitive to, and quickly impacted by, demand for the finished goods manufactured by its customers in these industries, which may change as a result of changes in regional or worldwide economies, currency exchange rates, energy prices or other factors beyond its control.

In particular, Howmet derives a significant portion of its revenue from products sold to the aerospace industry, which can be highly cyclical and reflective of changes in the general economy. The commercial aerospace industry is historically driven by the demand from commercial airlines for new aircraft and spare parts. The U.S. and international commercial aviation industries may face challenges arising from competitive pressures and fuel costs. Demand for commercial aircraft and spare parts is influenced by airline industry profitability, trends in airline passenger traffic, the state of U.S., regional and world economies, the ability of aircraft purchasers to obtain required financing and numerous other factors including the effects of terrorism, health and safety concerns (including as a result of the COVID-19 pandemic), environmental constraints imposed upon aircraft operators, the retirement of older aircraft, the performance and cost of alternative materials, and technological improvements to aircraft. The military aerospace cycle is highly dependent on U.S. and foreign government funding; however, it is also driven by the effects of terrorism, a changing global geopolitical environment, U.S. foreign policy, the retirement of older military aircraft, and technological improvements to new engines.

Further, the demand for Howmet’s commercial transportation products is driven by the number of vehicles produced by commercial transportation and automotive manufacturers. Commercial transportation and automotive sales and production are affected by many factors, including the age of the vehicle fleet and related scrappage rates, labor relations issues, fuel prices, regulatory requirements, government initiatives, trade agreements and levels of competition. The automotive industry is also sensitive to general economic conditions, including credit markets and interest rates, and consumer spending and preferences regarding vehicle ownership and usage, vehicle size, configuration and features.

Howmet is unable to predict the future course of industry variables, the strength of the U.S., regional or global economies, or the effects of government actions. Negative economic conditions, such as a major economic downturn, a prolonged recovery period, or disruptions in the financial markets, could have a material adverse effect on Howmet’s business, financial condition or results of operations.

Howmet could encounter manufacturing difficulties or other issues that impact product performance, quality or safety, which could adversely affect Howmet’s reputation, business and financial statements.

The manufacture of many of Howmet’s products is a highly exacting and complex process. Problems may arise during manufacturing for a variety of reasons, including equipment malfunction, failure to follow specific protocols, specifications and procedures, including those related to quality or safety, problems with raw materials, supply chain interruptions, natural disasters, labor unrest and environmental factors. Such problems could have an adverse impact on the Company’s ability to fulfill orders or meet product quality or performance. Product manufacturing or performance issues could result in recalls, customer penalties, contract cancellation and product liability exposure. Because of approval, license and qualification requirements applicable to manufacturers and/or their suppliers, alternatives to mitigate manufacturing disruptions may not be readily available to Howmet or its customers. Accordingly, manufacturing problems, product defects or other risks associated with our products, could result in significant costs to and liability for us that could have a material adverse effect on our business, financial condition or results of operations, including the payment of potentially substantial monetary damages, fines or penalties, as well as negative publicity and damage to our reputation, which could adversely impact product demand and customer relationships.

A material disruption of Howmet’s operations, particularly at one or more of its manufacturing facilities, could adversely affect Howmet’s business.

If Howmet’s operations, particularly one of its key manufacturing facilities, were to be disrupted as a result of significant equipment failures, natural disasters, power outages, fires, explosions, terrorism, theft, sabotage, adverse weather conditions, public health crises, labor disputes or other reasons, Howmet may be unable to effectively meet its obligations to or demand from its customers, which could adversely affect Howmet’s financial performance.

Interruptions in production could increase Howmet’s costs and reduce its sales. Any interruption in production capability could require the Company to incur costs for premium freight, make substantial capital expenditures, or purchase alternative material at higher costs to fill customer orders, which could negatively affect Howmet’s profitability and financial condition. Furthermore, a delivery delay by us due to production interruptions could subject us to liability from customer claims that such delay resulted in losses to the customer. Howmet maintains property damage insurance that the Company believes to be adequate to provide for reconstruction of facilities and equipment, as well as business interruption insurance to mitigate losses resulting from significant production interruption or shutdown caused by an insured loss. However, any recovery under Howmet’s insurance policies may not offset the lost profits or increased costs that may be experienced during the disruption of operations, which could adversely affect Howmet’s business, results of operations, financial condition and cash flow.

Information technology system failures, cyber attacks and security breaches may threaten the integrity of Howmet’s intellectual property and other sensitive information, disrupt its business operations, and result in reputational harm and other negative consequences that could have a material adverse effect on its financial condition and results of operations.

Howmet relies on its information technology systems to manage and operate its business, process transactions, and summarize its operating results. Howmet’s information technology systems could be subject to damage or interruption from power outages; computer, network and telecommunications failures; computer viruses; catastrophic events, such as fires, floods, earthquakes, tornadoes, hurricanes, acts of war or terrorism; and usage errors by employees. If Howmet’s information technology systems are damaged or cease to function properly, the Company may have to make a significant investment to fix or replace them, and Howmet may suffer loss of critical data and interruptions or delays in its operations. Any material disruption in the Company’s information technology systems, or delays or difficulties in implementing or integrating new systems or enhancing current systems, could have an adverse effect on Howmet’s business, financial condition or results of operations.

Howmet also faces global cybersecurity threats, which may range from uncoordinated individual attempts to sophisticated and targeted measures, known as advanced persistent threats, directed at the Company. Cyber attacks and security breaches may include, but are not limited to, attempts to access information, computer viruses, denial of service and other electronic security breaches.

The Company believes that it faces a heightened threat of cyber attacks due to the industries it serves, the locations of its operations and its technological innovations. The Company has experienced cybersecurity attacks in the past, including breaches of its information technology systems in which information was taken, and may experience them in the future, potentially with more frequency or sophistication. Based on information known to date, past attacks have not had a material impact on Howmet’s financial condition or results of operations. However, due to the evolving nature of cybersecurity threats, the scope and impact of any future incident cannot be predicted.

Howmet employs a number of measures to protect and defend against cyber attacks, including technical security controls, data encryption, firewalls, intrusion prevention systems, anti-virus software and frequent backups. Additionally, the Company conducts regular periodic training of its employees regarding the protection of sensitive information, which includes training intended to prevent the success of “phishing” attacks. While the Company continually works to safeguard its systems and mitigate potential risks, there is no assurance that such actions will be sufficient to prevent cyber attacks or security breaches that manipulate or improperly use the Company’s systems or networks, compromise confidential or otherwise protected information, destroy or corrupt data, or otherwise disrupt its operations. The occurrence of such events could negatively impact Howmet’s reputation and its competitive position and could result in litigation with third parties, regulatory action, loss of business, potential liability and increased remediation costs, any of which could have a material adverse effect on its financial condition and results of operations. In addition, such attacks or breaches could require significant management attention and resources, and could result in the diminution of the value of the Company’s investment in research and development.

Howmet’s enterprise risk management program and disclosure controls and procedures address cybersecurity and include elements intended to ensure that there is an analysis of potential disclosure obligations arising from cyber attacks and security breaches. Howmet also maintains compliance programs to address the potential applicability of restrictions against trading while in possession of material, nonpublic information generally and in connection with a cyber attack or security breach.

However, a breakdown in existing controls and procedures around the Company’s cybersecurity environment may prevent Howmet from detecting, reporting or responding to cyber incidents in a timely manner and could have a material adverse effect on the Company’s financial condition or the market price of its securities.

Howmet is dependent on a limited number of suppliers for a substantial portion of raw materials essential to our operations, and supply chain disruptions could have a material adverse effect on our business.

Howmet has supply arrangements with a limited number of suppliers for raw materials. We maintain annual or long-term contracts for a majority of our supply requirements, and for the remainder we depend on spot purchases. There can be no assurance that we will be able to renew, or obtain replacements for, any of our long-term contracts when they expire on terms that are as favorable as our existing agreements, or at all.

From time to time, increasing demand levels have caused regional supply constraints in the industry and further increases in demand levels could exacerbate these issues. Such constraints could impact our production or force us to purchase primary metal and other supplies from alternative sources, which may not be available in sufficient quantities or on terms that are favorable to us. Howmet could also have exposure if a key supplier is unable to deliver sufficient quantities of a necessary material on a timely basis. In addition, a significant downturn in the business or financial condition of a key supplier exposes us to the risk of default by the supplier on its contractual agreement, and this risk is increased by weak and deteriorating economic conditions on a global, regional or industry sector level. Any of the foregoing supply chain disruptions or those due to capacity constraints, trade barriers, labor shortages, business continuity, quality, cyber attacks, delivery issues or disruptions due to weather-related, natural disaster, or pandemic events could adversely affect Howmet’s operations and profitability.

Table of Contents

Howmet’s business could be adversely affected by increases in the cost or volatility in the availability of raw materials.

Howmet may be adversely affected by changes in the availability or cost of raw materials (including, but not limited to, nickel, titanium, aluminum, cobalt, vanadium and platinum), as well as freight costs associated with transportation of raw materials. The availability and costs of certain raw materials necessary for the production of Howmet’s products may be influenced by private or government entities including mergers and acquisitions, changes in geopolitical conditions or regulatory requirements (such as human rights regulations or environmental regulations), labor relations between the producers and their work forces, unstable governments in exporting nations, export quotas, sanctions, new or increased import duties, countervailing or anti-dumping duties, market forces of supply and demand, and inflation. In addition, from time to time, commodity prices may fall rapidly. When this happens, suppliers may withdraw capacity from the market until prices improve, which may cause periodic supply interruptions. Howmet may be unable to offset fully the effects of raw material shortages or higher costs through customer price increases, productivity improvements or cost reduction programs. Shortages or price fluctuations in raw materials could have a material adverse effect on Howmet’s operating results.

Howmet could be adversely affected by the loss of key customers or significant changes in the business or financial condition of its customers.

Howmet has long-term contracts with a significant number of its customers, some of which are subject to renewal, renegotiation or re-pricing at periodic intervals or upon changes in competitive supply conditions. Howmet’s failure to successfully renew, renegotiate or favorably re-price such agreements, or a material deterioration in or termination of these customer relationships, could result in a reduction or loss in customer purchase volume or revenue.

Additionally, a significant downturn or deterioration in the business or financial condition or loss of a key customer supplied by Howmet could affect Howmet’s financial results. Howmet’s customers may experience delays in the launch of new products, labor strikes, diminished liquidity or credit unavailability, weak demand for their products, or other difficulties in their businesses. For example, due to the grounding of the 737 MAX aircraft by regulatory authorities in March 2019, Boeing suspended production of the aircraft in January 2020 and resumed low-rate production in May 2020, which has resulted in a reduction in the Company’s sales. While regulatory authorities in the United States and certain other jurisdictions lifted grounding orders beginning in late 2020, our sales could continue to be negatively affected from the residual impacts of the 737 MAX grounding.

Howmet’s customers may also change their business strategies or modify their business relationships with Howmet, including to reduce the amount of Howmet’s products they purchase or to switch to alternative suppliers. If Howmet’s customers reduce, terminate or delay purchases from Howmet due to the foregoing factors or otherwise and Howmet is unsuccessful in enforcing its contract rights or replacing such business in whole or in part or replaces it with less profitable business, our financial condition and results of operations may be adversely affected.

Howmet could be adversely affected by reductions in defense spending.

Howmet’s products are used in a variety of military applications, including military aircraft. Although many of the programs in which Howmet participates extend several years, they are subject to annual funding through congressional appropriations. Changes in military strategy, policy and priorities, or reductions in defense spending, may affect current and future funding of these programs and could reduce the demand for Howmet’s products, which could adversely affect Howmet’s business, financial condition or results of operations.

Howmet may be unable to realize future targets or goals established for its business, or complete projects, at the levels, projected costs or by the dates targeted.

From time to time, Howmet may announce future targets or goals for its business, including revenue growth, cash generation, cost savings, restructuring plans, cost reductions and improvements in profitability. Future targets and goals reflect the Company’s beliefs and assumptions and are based on the Company’s then current expectations, its perception of historical trends, and estimates and projections about the environment, economies and markets in which Howmet operates, as well as other applicable factors. As such, they are inherently subject to significant business, economic, competitive and other uncertainties regarding future events, including the risks discussed in this report. The actual outcome may be materially different. Failure by the Company to achieve the targets or goals at the levels or by the dates targeted, if at all, may have a material adverse effect on its business, financial condition, results of operations or the market price of its securities.

In addition, the implementation of Howmet’s business strategy may involve the entry into and the execution of complex projects, which place significant demands on the Company’s management and personnel, and may depend on numerous factors beyond the Company’s control. There can be no assurance that such projects will be completed within budgeted costs, on a timely basis, or at all, whether due to the risks described in this report, or other factors. The failure to complete a material project as planned, or a significant delay in its execution, could have an adverse effect on Howmet’s business, financial condition or results of operations.

Howmet faces significant competition, which may have an adverse effect on profitability.

Table of Contents

As discussed in Part I, I tem 1 (Business-Competitive Conditions) of this report, the markets for Howmet’s products are highly competitive. Howmet’s competitors include a variety of both U.S. and non-U.S. companies in our product markets. New product offerings, new technologies in the marketplace or new facilities may compete with or replace Howmet products. The willingness of customers to accept substitutes for the products sold by Howmet, the ability of large customers to exert leverage in the marketplace to affect the pricing for Howmet’s products, and technological advancements or other developments by or affecting Howmet’s competitors or customers could adversely affect Howmet’s business, financial condition or results of operations.

In addition, Howmet may face increased competition due to industry consolidation. As companies attempt to strengthen or maintain their market positions in an evolving industry, companies could be acquired or merged. Companies that are strategic alliance partners in some areas of Howmet’s business may acquire or form alliances with Howmet’s competitors, thereby reducing their business with Howmet. Industry consolidation may result in stronger competitors who are better able to obtain favorable terms from suppliers or who are better able to compete as sole-source vendors for customers. Consolidation within Howmet’s customer base may result in customers who are better able to command increased leverage in negotiating prices and other terms of sale, which could adversely affect Howmet’s profitability. Moreover, if, as a result of increased leverage, customers require Howmet to reduce its pricing such that its gross margins are diminished, Howmet could decide not to sell certain products to a particular customer, or not to sell certain products at all, which would decrease Howmet’s revenue and could benefit its competitors. Consolidation within Howmet’s customer base may also lead to reduced demand for Howmet’s products if a combined entity replaces Howmet’s products with those of Howmet’s competitors with which it has prior relationships. The result of these developments could have a material adverse effect on Howmet’s business, operating results and financial condition.

Howmet may be unable to develop innovative new products or implement technology initiatives successfully.

Howmet’s competitive position and future performance depends, in part, on the Company’s ability to:

•identify and evolve with emerging technological and broader industry trends in Howmet’s end markets;

•identify and successfully execute on a strategy to remain an essential and sustainable element of our customers’ supply chains;

•fund, develop, manufacture and bring innovative new products to market quickly and cost-effectively;

•monitor disruptive technologies and understand customers’ and competitors’ abilities to deploy such technologies; and

•achieve sufficient return on investment for new products based on capital expenditures and research and development spending.

Howmet is working on new developments for a number of strategic projects, including advanced alloy development, engineered product design, and other advanced manufacturing technologies. While Howmet intends to continue to develop innovative new products and services, it may not be able to successfully differentiate its products or services from those of its competitors or match the level of research and development spending of its competitors, including those developing technology to displace Howmet’s current products. In addition, Howmet may not be able to adapt to evolving markets and technologies or achieve and maintain technological advantages. There can be no assurance that any of Howmet’s new products, development programs or technologies will be commercially adopted or be beneficial to Howmet.

Howmet’s business depends, in part, on its ability to meet increased program demand successfully and to mitigate the impact of program cancellations, reductions and delays.

Howmet is currently under contract to supply components for a number of new and existing commercial, general aviation, military aircraft and aircraft engine programs. Many of these contracts contemplate production increases over the next several years. If Howmet fails to meet production levels or encounters difficulty or unexpected costs in meeting such levels, it could have a material adverse effect on the Company’s business, financial condition or results of operations. Similarly, program cancellations, reductions or delays could also have a material adverse effect on Howmet’s business.

Risks Related to Legal and Regulatory Matters

Product liability, product safety, personal injury, property damage, and recall claims and investigations may materially affect Howmet’s financial condition and damage its reputation.

The manufacture and sale of our products expose Howmet to potential product liability, personal injury, property damage and related claims. These claims may arise from allegations of failure to meet product specifications, product design flaws and malfunction of products, as well as from misuse of our products, use of our products in an unintended, unapproved or unrecommended manner, or use of our products with systems not manufactured or sold by us. New data and information, including information about the ways in which Howmet’s products are used, may lead Howmet, regulatory authorities, government agencies or other entities or organizations to publish guidelines or recommendations, or impose restrictions, related to the manufacturing or use of Howmet’s products.

Table of Contents

In the event that a Howmet product fails to perform as expected, regardless of fault, or is used in an unexpected manner, and such failure or use results in, or is alleged to result in, bodily injury and/or property damage or other losses, Howmet may be subject to product liability lawsuits and other claims, or may be required or requested by its customers to participate in a recall or other corrective action involving such product. In addition, if a Howmet product is perceived to be defective or unsafe, Howmet’s sales could decrease, its reputation could be adversely impacted and it could be subject to further liability claims. Moreover, events that give rise to actual, potential or perceived product safety concerns could expose Howmet to government investigations or regulatory enforcement actions.

There can be no assurance that Howmet will be successful in defending any such proceedings or that insurance available to Howmet will be sufficient to cover any losses associated with such proceedings. An adverse outcome in one or more of these proceedings or investigations could: (i) have a material adverse effect on Howmet’s business, financial condition or profitability; (ii) impose substantial monetary damages and/or non-monetary penalties; (iii) result in additional litigation, regulatory investigations or other proceedings involving Howmet; (iv) result in loss of customers; (v) require changes to our products or business operations; or (vi) damage Howmet’s reputation and/or negatively impact the market price of Howmet’s common stock. Even if Howmet successfully defends against these types of claims, Howmet could still be required to spend a substantial amount of money in connection with legal proceedings or investigations with respect to such claims; Howmet’s management could be required to devote significant time, attention and operational resources responding to and defending against these claims and responding to these investigations; and Howmet’s reputation could suffer. Product liability claims and related lawsuits and investigations, product recalls, and allegations of product safety or quality issues, regardless of their validity or ultimate outcome, may have a material adverse effect on Howmet’s business, financial condition and reputation and on our ability to attract and retain customers.

Our business may be adversely affected if we fail to comply with government contracting regulations.

We derive a portion of our revenue from sales to U.S. and foreign governments and their respective agencies, as a subcontractor of their prime contractors. Such contracts are subject to various procurement laws and regulations and contract provisions relating to their formation, administration and performance. Failure to comply with these laws, regulations or provisions in our government contracts could result in the imposition of various civil and criminal penalties, termination of contracts, forfeiture of profits, suspension of payments, increased pricing pressure or suspension from future government contracting. If our government contracts are terminated, if we are suspended from government work, or if our ability to compete for new contracts is adversely affected, our financial condition and results of operation could be adversely affected.

Howmet’s global operations expose Howmet to risks that could adversely affect its business, financial condition, results of operations, cash flows or the market price of its securities.

Howmet has operations or activities in numerous countries and regions outside the United States, including Europe, Canada, Mexico, China, and Japan. As a result, Howmet’s global operations are affected by economic, political and other conditions in the foreign countries in which Howmet does business, as well as U.S. laws regulating international trade, including:

•economic and commercial instability risks, including those caused by sovereign and private debt default, corruption, and changes in local government laws, regulations and policies, such as those related to tariffs, sanctions and trade barriers (including tariffs imposed by the United States as well as retaliatory tariffs imposed by China or other foreign entities), taxation, data privacy, exchange controls, employment regulations and repatriation of assets or earnings;

•geopolitical risks such as political instability, civil unrest, expropriation, nationalization of properties by a government, imposition of sanctions, and renegotiation or nullification of existing agreements;

•war, terrorist activities, kidnapping of personnel or other dangerous conditions;

•major public health issues, such as an outbreak of a pandemic or epidemic (such as Sudden Acute Respiratory Syndrome, Avian Influenza, H7N9 virus, coronavirus (including COVID-19), and the Ebola virus), which could cause disruptions in Howmet’s operations, workforce, supply chain or end markets;

•difficulties enforcing contractual rights and intellectual property, including a lack of remedies for misappropriation in certain jurisdictions;

•changes in trade and tax laws that may result in our customers being subjected to increased taxes, duties and tariffs and reduce their willingness to use our services in countries in which we are currently manufacturing their products;

•compliance with antitrust and competition regulations;

•rising labor costs or labor unrest, including strikes;

•compliance with foreign labor laws, which generally provide for increased notice, severance and consultation requirements as compared to U.S. laws;

•aggressive, selective or lax enforcement of laws and regulations by foreign governmental authorities;

•compliance with the Foreign Corrupt Practices Act and other anti-bribery and corruption laws;

Table of Contents

•compliance with U.S. laws concerning trade, including the International Traffic in Arms Regulations, the Export Administration Regulations, and the sanctions, regulations and embargoes administered by the U.S. Department of Treasury’s Office of Foreign Assets Control;

•imposition of currency controls; and

•adverse tax audit rulings.

Although the effect of any of the foregoing factors is difficult to predict, any one or more of them could adversely affect Howmet’s business, financial condition, or results of operations. The Company’s international operations subject Howmet to complex and dynamic laws and regulations that, in some cases, could result in conflict or inconsistency between applicable laws of different jurisdictions and/or legal obligations. While Howmet believes it has adopted appropriate risk management, compliance programs and insurance arrangements to address and reduce the associated risks, such measures may provide inadequate protection against costs, penalties, liabilities or other potential risks such as loss of export privileges or repatriation of assets that may arise from such events.

Howmet may face challenges to its intellectual property rights which could adversely affect the Company’s reputation, business and competitive position.

Howmet owns important intellectual property, including patents, trademarks, copyrights and trade secrets. The Company’s intellectual property plays an important role in maintaining Howmet’s competitive position in a number of the markets that the Company serves. Howmet’s competitors may develop technologies that are similar or superior to Howmet’s proprietary technologies or design around the patents Howmet owns or licenses. Despite its controls and safeguards, Howmet’s technology may be misappropriated by its employees, its competitors or other third parties. The pursuit of remedies for any misappropriation of Howmet intellectual property is expensive and the ultimate remedies may be deemed insufficient. Further, in jurisdictions where the enforcement of intellectual property rights is less robust, the risk of misappropriation of Howmet intellectual property increases, despite efforts the Company undertakes to protect it. Developments or assertions by or against Howmet relating to intellectual property rights, and any inability to protect or enforce Howmet’s rights sufficiently, could adversely affect Howmet’s business and competitive position.

Howmet may be exposed to significant legal proceedings, investigations or changes in U.S. federal, state or foreign law, regulation or policy.

Howmet’s results of operations or liquidity in a particular period could be affected by new or increasingly stringent laws, regulatory requirements or interpretations, or outcomes of significant legal proceedings or investigations adverse to Howmet. The Company may experience an unfavorable change in effective tax rates or become subject to unexpected or rising costs associated with business operations or provision of health or welfare benefits to employees due to changes in laws, regulations or policies.

Howmet is also subject to a variety of legal and regulatory compliance risks in the United States and abroad in connection with its business and products. These risks include, among other things, potential claims relating to product liability, product testing, health and safety, environmental matters, employment matters, required record keeping and record retention, compliance with securities laws, intellectual property rights, government contracts and taxes, insurance or commercial matters, as well as compliance with U.S. and foreign laws and regulations, including those governing import and export, anti-bribery, antitrust and competition, sales and trading practices, human rights and modern slavery, sourcing of raw materials, third-party relationships, supply chain operations and the manufacture and sale of products. Howmet may be a party to litigation in a foreign jurisdiction where geopolitical risks might influence the ultimate outcome of such litigation. Howmet could be subject to fines, penalties, damages (in certain cases, treble damages), or suspension or debarment from government contracts.

The global and diverse nature of Howmet’s operations means that these risks will continue to exist, and additional legal proceedings and contingencies may arise from time to time. While Howmet believes it has adopted appropriate risk management and compliance programs to address and reduce these risks, including insurance arrangements with respect to these risks, such measures may provide inadequate protection against liabilities that may arise. In addition, various factors or developments can lead the Company to change current estimates of liabilities or make such estimates for matters previously unsusceptible to reasonable estimates, such as a significant judicial ruling or judgment, a significant settlement, significant regulatory developments or changes in applicable law. A future adverse ruling or settlement or unfavorable changes in laws, regulations or policies, or other contingencies that the Company cannot predict with certainty could have a material adverse effect on the Company’s financial condition, results of operations or cash flows in a particular period. Litigation and compliance efforts may require substantial attention from management and could result in significant legal expenses, settlement costs or damage awards that could have a material impact on the Company’s financial position, results of operations and cash flows. For additional information regarding the legal proceedings involving the Company, see Part I, Item 3 (Legal Proceedings) of this report and in Note V to the Consolidated Financial Statements in Part II, Item 8.

Unanticipated changes in Howmet’s tax provisions or exposure to additional tax liabilities could affect Howmet’s future profitability.

Table of Contents

Howmet is subject to income taxes in both the United States and various non-U.S. jurisdictions. Its domestic and international tax liabilities are dependent upon the distribution of income among these different jurisdictions. Changes in applicable domestic or foreign tax laws and regulations, or their interpretation and application, including the possibility of retroactive effect, could affect the Company’s tax expense and profitability. Howmet’s tax expense includes estimates of additional tax that may be incurred for tax exposures and reflects various estimates and assumptions. The assumptions include assessments of future earnings of the Company that could impact the valuation of its deferred tax assets. The Company’s future results of operations could be adversely affected by changes in the effective tax rate as a result of a change in the mix of earnings in countries with differing statutory tax rates, changes in the overall profitability of the Company, changes in tax legislation and rates, changes in generally accepted accounting principles, changes in the valuation of deferred tax assets and liabilities, the results of tax audits and examinations of previously filed tax returns or related litigation and continuing assessments of its tax exposures.

Corporate tax law changes continue to be analyzed in the United States and in many other jurisdictions. In particular, on December 22, 2017, the Tax Cuts and Jobs Act (the “2017 Act”) was signed into law, significantly reforming the U.S. Internal Revenue Code of 1986, as amended. During 2018, the Internal Revenue Service (the “IRS”) began a number of guidance projects which serve to both interpret and implement the 2017 Act. Those guidance projects, which include both Proposed and Final Treasury Regulations, continued into 2020. Howmet continues to review the ongoing interpretive guidance and evaluate its consequences. The ultimate impact of the 2017 Act may differ from reported amounts due to, among other things, changes resulting from such ongoing guidance. Further, we cannot predict the impact of any efforts to change or repeal the 2017 Act or enact alternative legislation by the new presidential administration or Congress.

Labor disputes and other employee relations issues could adversely affect Howmet’s business, financial condition or results of operations.

A significant portion of Howmet’s employees are represented by labor unions in a number of countries under various collective bargaining agreements with varying durations and expiration dates. For more information, see “Employees” in Part I, Item 1 (Business) of this report. While Howmet previously has been successful in renegotiating its collective bargaining agreements with various unions, Howmet may not be able to satisfactorily renegotiate all collective bargaining agreements in the United States and other countries when they expire. In addition, existing collective bargaining agreements may not prevent a strike or work stoppage at Howmet’s facilities in the future. Howmet may also be subject to general country strikes or work stoppages unrelated to its business or collective bargaining agreements. Any such work stoppages (or potential work stoppages) could have a material adverse effect on Howmet’s business, financial condition or results of operations.

Howmet is subject to privacy and data security/protection laws in the jurisdictions in which it operates and may be exposed to substantial costs and liabilities associated with such laws and regulations.

The regulatory environment surrounding information security and privacy is increasingly demanding, with frequent imposition of new and changing requirements. For example, the European Union’s General Data Protection Regulation (“GDPR”), which became effective in May 2018, imposed significant new requirements on how companies process and transfer personal data, as well as significant fines for non-compliance. Compliance with changes in privacy and information security laws and standards may result in significant expense due to increased investment in technology and the development of new operational processes, which could have a material adverse effect on Howmet’s financial condition and results of operations. In addition, the payment of potentially significant fines or penalties in the event of a breach of the GDPR or other privacy and information security laws, as well as the negative publicity associated with such a breach, could damage the Company’s reputation and adversely impact product demand and customer relationships.

Failure to comply with domestic or international employment and related laws could result in penalties or costs that could have a material adverse effect on Howmet’s business results.

Howmet is subject to a variety of domestic and foreign employment laws, such as the Fair Labor Standards Act (which governs such matters as minimum wages, overtime and other working conditions), state and local wage laws, the Employee Retirement Income Security Act, and regulations related to safety, discrimination, organizing, whistle-blowing, classification of employees, privacy and severance payments, citizenship requirements, and healthcare insurance mandates. Allegations that Howmet has violated such laws or regulations could damage the Company’s reputation and lead to fines from or settlements with federal, state or foreign regulatory authorities or damages payable to employees, which could have a material adverse impact on Howmet’s operations and financial condition.

Howmet is exposed to environmental, health and safety risks and is subject to a broad range of health, safety and environmental laws and regulations which may result in substantial costs and liabilities.

Howmet’s operations worldwide are subject to numerous complex and increasingly stringent health, safety and environmental laws and regulations. The costs of complying with such laws and regulations, including participation in assessments and cleanups of sites, as well as internal voluntary programs, are significant and will continue to be so for the foreseeable future. Environmental laws may impose cleanup liability on owners and occupiers of contaminated property, including present, past or divested properties, regardless of whether the owners and occupiers caused the contamination or whether the activity that

Table of Contents

caused the contamination was lawful at the time it was conducted. Environmental matters for which Howmet may be liable may arise in the future at its present sites, at sites owned or operated by its predecessors or affiliates, at sites that it may acquire in the future, or at third-party sites used by Howmet, its predecessors or affiliates for material and waste handling and disposal. Compliance with health, safety and environmental laws and regulations, including remediation obligations, may prove to be more challenging and costly than the Company anticipates. Howmet’s results of operations or liquidity in a particular period could be affected by certain health, safety or environmental matters, including remediation costs and damages related to certain sites as well as other health and safety risks relating to its operations and products. Additionally, evolving regulatory standards and expectations can result in increased litigation and/or increased costs, including increased remediation costs, all of which can have a material and adverse effect on the Company’s financial condition, results of operations and cash flows.

In addition, the industrial activities conducted at Howmet’s facilities present a significant risk of injury or death to our employees, customers or third parties that may be on site. We have experienced serious injuries in the past, notwithstanding the safety protocols, practices and precautions we take. Our operations are subject to regulation by various federal, state and local agencies in the United States and regulation by foreign government entities abroad responsible for employee health and safety, including the Occupational Safety and Health Administration. From time to time, we have incurred fines for violations of various health and safety standards. In addition to industrial activities, the global COVID-19 pandemic will continue to significantly impact the health of our employees and increase the cost of health and safety measures within our operations. Significant community transmission in the vicinity of our operations is likely to impact the workforce availability due to quarantine and isolation practices. Social distancing, mask use, testing and other measures increase costs of operation. While we maintain insurance and have in place policies to minimize risks associated with industrial activities and COVID-19, we may nevertheless be unable to avoid material liabilities relating to any injury, death or other workers compensation claims. These types of incidents may not be covered by or may exceed our insurance coverage and could have a material adverse effect on our results of operations and financial condition or result in negative publicity and/or significant reputational harm.

Howmet may be affected by global climate change or by legal, regulatory, or market responses to such change.

Increased concern over climate change has led to new and proposed legislative and regulatory initiatives, such as cap-and-trade systems, additional limits on emissions of greenhouse gases or Corporate Average Fuel Economy (“CAFE”) standards in the United States. New or revised laws and regulations in this area could directly and indirectly affect Howmet and its customers and suppliers, including by increasing the costs of production or impacting demand for certain products, which could result in an adverse effect on our financial condition, results of operations and cash flows. Compliance with any new or more stringent laws or regulations, or stricter interpretations of existing laws, could require additional expenditures by the Company or its customers or suppliers. Also, Howmet relies on natural gas, electricity, fuel oil and transport fuel to operate its facilities. Any increased costs of these energy sources because of new laws could be passed along to the Company and its customers and suppliers, which could also have a negative impact on Howmet’s profitability.

Physical risk associated with climate change may result in an increase of the exposure and impact of events with damage due to flooding, extreme winds and extreme precipitation for Howmet locations, suppliers or customers. Prolonged periods of drought may result in wildfires, which may have an adverse effect on production capacity of Howmet sites, suppliers and customers. While we maintain insurance coverage, these types of incidents may not be covered by or may exceed our insurance coverage and could have a material adverse effect on our results of operations and financial condition.

Risks Related to Liquidity and Capital Resources

A decline in Howmet’s financial performance or outlook or a deterioration in its credit profile could negatively impact the Company’s access to capital markets, its liquidity and its borrowing costs.

Howmet has significant capital requirements and depends, in part, upon the issuance of debt to fund its operations and contractual commitments and pursue strategic actions. A decline in the Company’s financial performance or outlook due to internal or external factors could affect the Company’s access to, and the availability or cost of, financing on acceptable terms and conditions. There can be no assurance that Howmet will have access to the global capital market on terms the Company finds acceptable. Limitations on Howmet’s ability to access the global capital markets, a reduction in the Company’s liquidity or an increase in borrowing costs could materially and adversely affect Howmet’s ability to maintain or grow its business, which in turn may adversely affect its financial condition and results of operations.

A downgrade of Howmet’s credit ratings could limit its ability to obtain future financing, increase borrowing costs and costs relating to credit facilities, adversely affect the market price of Howmet securities, trigger collateral postings, or otherwise impair its business, financial condition, and results of operations.

Howmet’s credit ratings are important to the Company’s cost of capital. The major credit rating agencies evaluate our creditworthiness and give us specified credit ratings. These ratings are based on a number of factors, including our financial strength and financial policies as well as our strategies, operations, execution and timeliness of financial reporting. These credit ratings are limited in scope, and do not address all material risks related to investment in us, but rather reflect only the view of each rating agency at the time the rating is issued. Nonetheless, the credit ratings Howmet receives impact our borrowing costs

Table of Contents

as well as the terms upon which we will have access to capital. Failure to maintain sufficiently high credit ratings could adversely affect the interest rate in future financings, our liquidity or our competitive position, and could also restrict our access to capital markets. For information on our credit ratings, see "Liquidity and Capital Resources" in Part II, Item 7 (Management’s Discussion and Analysis of Financial Condition and Results of Operations).

There can be no assurance that one or more of the credit rating agencies will not take negative actions with respect to Howmet’s ratings in the future. Increased debt levels, macroeconomic conditions, a deterioration in the Company’s debt protection metrics, a contraction in the Company’s liquidity, or other factors could potentially trigger such actions. A rating agency may lower, suspend or withdraw entirely a rating or place it on negative outlook or watch if, in that rating agency’s judgment, circumstances so warrant. A downgrade of Howmet’s credit ratings by one or more rating agencies could result in adverse consequences, including: (i) adversely impact the market price of Howmet securities; (ii) adversely affect existing financing (for example, a downgrade by S&P or Moody’s would subject Howmet to higher costs under the Credit Agreement); (iii) limit access to the capital (including commercial paper) or credit markets or otherwise adversely affect the availability of other new financing on favorable terms, if at all; (iv) result in more restrictive covenants in agreements governing the terms of any future indebtedness that the Company incurs; (v) increase the cost of borrowing or fees on undrawn credit facilities; or (vi) result in vendors or counterparties seeking collateral or letters of credit from Howmet.

Limitations on Howmet’s ability to access the global capital markets, a reduction in Howmet’s liquidity or an increase in borrowing costs could materially and adversely affect Howmet’s ability to maintain or grow its business, which in turn may adversely affect its financial condition, liquidity and results of operations.

Howmet’s business and growth prospects may be negatively impacted by limits in its capital expenditures.

Howmet requires substantial capital to invest in growth opportunities and to maintain and prolong the life and capacity of its existing facilities. Insufficient cash generation or capital project overruns may negatively impact Howmet’s ability to fund as planned its sustaining and return-seeking capital projects. Over the long term, Howmet’s ability to take advantage of improved market conditions or growth opportunities in its businesses may be constrained by earlier capital expenditure restrictions, which could adversely affect the long-term value of its business and the Company’s position in relation to its competitors.

An adverse decline in the liability discount rate, lower-than-expected investment return on pension assets and other factors could adversely affect Howmet’s results of operations or amount of pension funding contributions in future periods.

Howmet’s results of operations may be negatively affected by the amount of expense Howmet records for its pension and other postretirement benefit plans, reductions in the fair value of plan assets and other factors. Howmet calculates income or expense for its plans using actuarial valuations in accordance with accounting principles generally accepted in the United States of America ("GAAP").

These valuations reflect assumptions about financial market and other economic conditions, which may change based on changes in key economic indicators. The most significant year-end assumptions used by Howmet to estimate pension or other postretirement benefit income or expense for the following year are the discount rate applied to plan liabilities and the expected long-term rate of return on plan assets. In addition, Howmet is required to make an annual measurement of plan assets and liabilities, which may result in a significant charge to shareholders’ equity. For a discussion regarding how Howmet’s financial statements can be affected by pension and other postretirement benefits accounting policies, see “Critical Accounting Policies and Estimates—Pension and Other Postretirement Benefits” in Part II, Item 7 (Management’s Discussion and Analysis of Financial Condition and Results of Operations) and Note H to the Consolidated Financial Statements in Part II, Item 8. Although GAAP expense and pension funding contributions are impacted by different regulations and requirements, the key economic factors that affect GAAP expense would also likely affect the amount of cash or securities Howmet would contribute to the pension plans.

Potential pension contributions include both mandatory amounts required under federal law and discretionary contributions to improve the plans’ funded status. The Moving Ahead for Progress in the 21st Century Act (“MAP-21”), enacted in 2012, provided temporary relief for employers like Howmet who sponsor defined benefit pension plans related to funding contributions under the Employee Retirement Income Security Act of 1974 by allowing the use of a 25-year average discount rate within an upper and lower range for purposes of determining minimum funding obligations. In 2014, the Highway and Transportation Funding Act ("HATFA") extended the relief provided by MAP-21 and modified the interest rates that had been set by MAP-21. In 2015, the Bipartisan Budget Act of 2015 ("BBA 2015") extended the relief period provided by HATFA. Howmet believes that the relief provided by BBA 2015 will moderately reduce the cash flow sensitivity of the Company’s U.S. pension plans’ funded status over the next several years due to recent and potential future declines in discount rates. However, higher than expected pension contributions due to a decline in the plans’ funded status as a result of unpredictable future declines in the discount rate or lower-than-expected investment returns on plan assets could have a material negative effect on the Company’s cash flows. Adverse capital market conditions could result in reductions in the fair value of plan assets and increase the Company’s liabilities related to such plans, which could adversely affect our liquidity and results of operations.

Table of Contents

Howmet is exposed to fluctuations in foreign currency exchange rates and interest rates, as well as inflation, economic factors, and currency controls in the countries in which it operates.

Economic factors, including inflation and fluctuations in foreign currency exchange rates and interest rates, competitive factors in the countries in which Howmet operates, and volatility or deterioration in the global economic and financial environment could affect Howmet’s revenue, expenses and results of operations. Changes in the valuation of the U.S. dollar against other currencies, including the Euro, British pound, Canadian dollar, Chinese yuan (renminbi), and Japanese yen, may affect Howmet’s profitability.

In addition, a portion of Howmet’s indebtedness, including borrowings, if any, under the Company’s Five-Year Credit Facility, bears interest at rates equal to the London Interbank Offering Rate (“LIBOR”) plus an applicable margin based on the credit ratings of Howmet’s outstanding senior unsecured long-term debt. Accordingly, the Company is subject to risk from changes in interest rates on the variable component of the rate. Further, LIBOR is the subject of recent national, international and other regulatory guidance and proposals for reform. These reforms and other pressures may cause LIBOR to disappear entirely or to perform differently than in the past. The consequences of these developments cannot be entirely predicted, but could include changes in the cost of Howmet’s variable rate indebtedness.

Howmet also faces risks arising from the imposition of cash repatriation restrictions and exchange controls. Cash repatriation restrictions and exchange controls may limit the Company’s ability to convert foreign currencies into U.S. dollars or to remit dividends and other payments by Howmet’s foreign subsidiaries or businesses located in or conducted within a country imposing restrictions or controls. While Howmet currently has no need, and does not intend, to repatriate or convert cash held in countries that have significant restrictions or controls in place, should the Company need to do so to fund its operations, it may be unable to repatriate or convert such cash, or be unable to do so without incurring substantial costs. Howmet currently has operations in countries that have cash repatriation restrictions or exchange controls in place, including China, and, if the Company were to need to repatriate or convert such cash, these controls and restrictions may have an adverse effect on Howmet’s operating results and financial condition.

Dividends and share repurchases fall within the discretion of our Board of Directors, depend on a number of factors, and are subject to limits under the Company’s Credit Agreement.

Share repurchases and the declaration of dividends fall within the discretion of Howmet’s Board of Directors, and the Board’s decision regarding such matters depends on many factors, including Howmet’s financial condition, earnings, capital requirements, debt service obligations, covenants associated with certain of the Company’s debt obligations, industry practice, legal requirements, regulatory constraints and other factors that the Board deems relevant. In addition, under the Company’s amendment to the Credit Agreement, during the period from June 30, 2020 through December 31, 2021 (unless the Company ends this period earlier in accordance with the amendment or otherwise), common stock dividends and share repurchases are permitted only if no borrowings are outstanding under the Credit Agreement and are limited to an aggregate amount of $100 million through June 30, 2021, with such limit increasing to an aggregate amount of $250 million after June 30, 2021 if the Consolidated Net Debt to Consolidated EBITDA ratio is no greater than 3.75 to 1.00. The Company suspended dividends in April 2020 to preserve cash and provide flexibility in light of the impact of the COVID-19 pandemic. Since June 30, 2020, the Company has repurchased approximately $73 million of its common stock. There can be no assurance that the Company will declare dividends or repurchase stock in the future in any particular amounts, or at all.

General Risks

Failure to attract and retain a highly skilled and diverse global workforce, or provide adequate succession plans for key personnel could adversely affect Howmet’s operations and competitiveness.

Howmet’s global operations require highly skilled personnel with relevant industry and technical experience. Shortages in certain skills, in areas such as engineering, manufacturing and technology and other labor market inadequacies have created more competition for talent among us and other companies both within and outside of our industry. If the Company fails to attract, develop and retain a diverse global workforce with the skills and in the locations we need to operate and grow our business, our operations could be adversely impacted.

In addition, the continuity of key personnel and the preservation of institutional knowledge are vital to the success of the Company’s growth and business strategy. The loss of key members of management and other personnel could significantly harm Howmet’s business, and any unplanned turnover, or failure to develop adequate succession plans for key positions, could deplete the Company’s institutional knowledge base, result in loss of technical or other expertise, delay or impede the execution of the Company’s business plans and erode Howmet’s competitiveness.

Howmet may be unable to realize the expected benefits from acquisitions, divestitures and strategic alliances.

Howmet has made, and may continue to plan and execute, acquisitions and divestitures and take other actions to grow its business or streamline its portfolio. There is no assurance that anticipated benefits will be realized. Acquisitions present significant challenges and risks, including the effective integration of the business into the Company, unanticipated costs and

Table of Contents

liabilities, and the ability to realize anticipated benefits, such as growth in market share, revenue or margins, at the levels or in the timeframe expected. The Company may be unable to manage acquisitions successfully. Additionally, adverse factors may prevent Howmet from realizing the benefits of its growth projects, including unfavorable global economic conditions, currency fluctuations, or unexpected delays in target timelines.

With respect to portfolio optimization actions such as divestitures, curtailments and closures, Howmet may face barriers to exit from unprofitable businesses or operations, including high exit costs or objections from customers, suppliers, unions, local or national governments, or other stakeholders. In addition, Howmet may retain unforeseen liabilities for divested entities or businesses, including, but not limited to, if a buyer fails to honor all commitments. Howmet’s business operations are capital intensive, and curtailment or closure of operations or facilities may include significant charges, including employee separation costs, asset impairment charges and other measures.

In addition, Howmet has participated in, and may continue to participate in, strategic alliances, joint ventures and other similar arrangements from time to time. Strategic alliances and joint ventures inherently involve special risks. Even if Howmet holds majority interests or maintains operational control in such arrangements, its partners may have opposing economic or business interests, exercise veto rights to block Howmet actions, take action contrary to Howmet’s policies or objectives, or, as a result of financial or other difficulties, be unable to fulfill their obligations.

There can be no assurance that acquisitions, growth investments, divestitures, closures, strategic alliances, joint ventures or similar arrangements will be undertaken or completed in their entirety as planned or that they will be beneficial to Howmet, whether due to the above-described risks, unfavorable global economic conditions, increases in costs, currency fluctuations, geopolitical risks, or other factors.

Anti-takeover provisions could prevent or delay a change in control of Howmet, including a takeover attempt by a third party and limit the power of Howmet’s shareholders.

Howmet’s Certificate of Incorporation and Bylaws contain, and Delaware law contains, provisions that are intended to deter coercive takeover practices and inadequate takeover bids by making such practices or bids unacceptably expensive to the bidder and to encourage prospective acquirers to negotiate with Howmet’s Board of Directors rather than to attempt a hostile takeover. For example, Howmet is subject to Section 203 of the Delaware General Corporation Law, which imposes certain restrictions on mergers and other business combinations between the Company and any holder of 15% or more of the Company’s outstanding common stock, which could make it more difficult for another party to acquire Howmet. Additionally, the Company’s Certificate of Incorporation authorizes Howmet’s Board of Directors to issue preferred stock or adopt other anti-takeover measures without stockholder approval. These provisions may apply even if an offer may be considered beneficial by some stockholders and could delay or prevent an acquisition that Howmet’s Board of Directors determines is not in the best interests of Howmet’s shareholders. These provisions may also limit the price that investors might be willing to pay in the future for shares of Howmet common stock or prevent or discourage attempts to remove and replace incumbent directors.

Arconic Corporation may fail to perform under various transaction agreements that were executed as part of the Arconic Inc. Separation Transaction.

In connection with the Arconic Inc. Separation Transaction, we entered into a separation and distribution agreement with Arconic Corporation and also entered into various other agreements, including a tax matters agreement, an agreement related to the Davenport plant, an employee matters agreement, intellectual property license agreements, metal supply agreements and real estate and office leases. The separation and distribution agreement, the tax matters agreement and the employee matters agreement, together with the documents and agreements by which the internal reorganization of the Company prior to the separation was effected, determined the allocation of assets and liabilities between us and Arconic Corporation following the Arconic Inc. Separation Transaction for those respective areas and included any necessary indemnifications related to liabilities and obligations. We will rely on Arconic Corporation to satisfy its performance and payment obligations under these agreements. If Arconic Corporation is unable or unwilling to satisfy its obligations under these agreements, including its indemnification obligations, we could incur operational difficulties and/or losses.

In connection with the Arconic Inc. Separation Transaction, Arconic Corporation agreed to indemnify us for certain liabilities and we agreed to indemnify Arconic Corporation for certain liabilities. If we are required to pay under these indemnities to Arconic Corporation, our financial results could be negatively impacted. The Arconic Corporation indemnity may not be sufficient to hold us harmless from the full amount of liabilities for which Arconic Corporation is allocated responsibility, and Arconic Corporation may not be able to satisfy its indemnification obligations in the future.

Pursuant to the separation and distribution agreement and certain other agreements with Arconic Corporation, Arconic Corporation has agreed to indemnify us for certain liabilities, and we have agreed to indemnify Arconic Corporation for certain liabilities, in each case for uncapped amounts. Indemnities that we may be required to provide Arconic Corporation are not subject to any cap, may be significant and could negatively impact our business. Third parties could also seek to hold us responsible for any of the liabilities that Arconic Corporation has agreed to retain. Any amounts we are required to pay pursuant to these indemnification obligations and other liabilities could require us to divert cash that would otherwise have been used in

Table of Contents

furtherance of the Company’s operations. Further, the indemnity from Arconic Corporation may not be sufficient to protect us against the full amount of such liabilities, and Arconic Corporation may not be able to fully satisfy its indemnification obligations. Moreover, even if we ultimately succeed in recovering from Arconic Corporation any amounts for which we are held liable, we may be temporarily required to bear such losses. Each of these risks could negatively affect our business, results of operations and financial condition.

The Arconic Inc. Separation Transaction could result in substantial tax liability.

It was a condition to the Distribution of Arconic that we receive an opinion of our outside counsel, satisfactory to our Board of Directors, regarding the qualification of the distribution, together with certain related transactions, as a “reorganization” within the meaning of Sections 355 and 368(a)(1)(D) of the Internal Revenue Code of 1986, as amended (the “Code”). This condition was satisfied prior to the Distribution of Arconic. However, the opinion of counsel was based upon and relied on, among other things, various facts and assumptions, as well as certain representations, statements and undertakings by us and Arconic Corporation, including those relating to the past and future conduct by us and Arconic Corporation. If any of these facts, assumptions, representations, statements or undertakings is, or becomes, inaccurate or incomplete, or if we or Arconic Corporation breach any of our representations or covenants contained in the separation agreement and certain other agreements and documents or in any documents relating to the opinion of counsel, the opinion of counsel may be invalid and the conclusions reached therein could be jeopardized.

Notwithstanding our receipt of the opinion of counsel, the Internal Revenue Service (the “IRS”) could determine that the Distribution of Arconic and/or certain related transactions should be treated as taxable transactions for U.S. federal income tax purposes if it determines that any of the representations, assumptions or undertakings upon which the opinion of counsel was based are false or have been violated. In addition, the opinion of counsel represents the judgment of such counsel and is not binding on the IRS or any court, and the IRS or a court may disagree with the conclusions in the opinion of counsel. Accordingly, notwithstanding receipt of the opinion of counsel, there can be no assurance that: (i) the IRS will not assert that the Distribution of Arconic and/or certain related transactions do not qualify for tax-free treatment for U.S. federal income tax purposes; or (ii) a court would not sustain such a challenge. In the event the IRS were to prevail with such challenge, we, our stockholders and Arconic Corporation, could be subject to significant U.S. federal income tax liability.

If the Distribution of Arconic fails to qualify as a transaction that is generally tax-free for U.S. federal income tax purposes under Sections 355 and 368(a)(1)(D) of the Code, in general, for U.S. federal income tax purposes, we would recognize taxable gain as if we had sold the Arconic Corporation common stock in a taxable sale for its fair market value, and our stockholders who received such Arconic Corporation shares in the Distribution of Arconic would be subject to tax as if they had received a taxable distribution equal to the fair market value of such shares.

Under current U.S. federal income tax law, even if the Distribution of Arconic, together with certain related transactions, otherwise qualifies for tax-free treatment under Sections 355 and 368(a)(1)(D) of the Code, the Distribution of Arconic may nevertheless be rendered taxable to us as a result of certain post-distribution transactions, including certain acquisitions of shares or assets of ours or Arconic Corporation. Under the tax matters agreement entered into between us and Arconic Corporation in connection with the Arconic Inc. Separation Transaction, Arconic Corporation may be required to indemnify us for any taxes resulting from the Arconic Inc. Separation Transaction (and any related costs and other damages) to the extent such amounts resulted from (i) an acquisition of all or a portion of the equity securities or assets of Arconic Corporation, whether by merger or otherwise (and regardless of whether we participated in or otherwise facilitated the acquisition), (ii) other actions or failures to act by Arconic Corporation, or (iii) any of Arconic Corporation’s representations, covenants or undertakings contained in the separation agreement and certain other agreements and documents or in any documents relating to the opinion of counsel being incorrect or violated. However, the indemnity from Arconic Corporation may not be sufficient to protect us against the full amount of such additional taxes or related liabilities, and Arconic Corporation may not be able to fully satisfy its indemnification obligations. Moreover, even if we ultimately succeed in recovering from Arconic Corporation any amounts for which we are held liable, we may be temporarily required to bear such losses. In addition, we and our subsidiaries may incur certain tax costs in connection with the Arconic Inc. Separation Transaction, including non-U.S. tax costs resulting from transactions (including the internal reorganization) in non-U.S. jurisdictions, which may be material. Each of these risks could negatively affect our business, results of operations and financial condition.

The Alcoa Inc. Separation Transaction could result in substantial tax liability.

It was a condition to the Distribution of Alcoa that (i) the private letter ruling from the Internal Revenue Service (the “IRS”) regarding certain U.S. federal income tax matters relating to the Alcoa Inc. Separation Transaction and the Distribution of Alcoa received by Howmet remain valid and be satisfactory to Howmet’s Board of Directors and (ii) Howmet receive an opinion of its outside counsel, satisfactory to the Board of Directors, regarding the qualification of the Distribution of Alcoa, together with certain related transactions, as a transaction that is generally tax-free, for U.S. federal income tax purposes, under Sections 355 and 368(a)(1)(D) of the Internal Revenue Code of 1986, as amended (the “Code”). Both of these conditions were satisfied prior to the Distribution of Alcoa. However, the IRS private letter ruling and the opinion of counsel were based upon and relied on, among other things, various facts and assumptions, as well as certain representations, statements and

Table of Contents

undertakings of Howmet and Alcoa Corporation, including those relating to the past and future conduct of Howmet and Alcoa Corporation. If any of these representations, statements or undertakings is, or becomes, inaccurate or incomplete, or if Howmet or Alcoa Corporation breaches any of its representations or covenants contained in any of the Alcoa Inc. Separation Transaction-related agreements and documents or in any documents relating to the IRS private letter ruling and/or the opinion of counsel, the IRS private letter ruling and/or the opinion of counsel may be invalid and the conclusions reached therein could be jeopardized.

Notwithstanding Howmet’s receipt of the IRS private letter ruling and the opinion of counsel, the IRS could determine that the Distribution of Alcoa and/or certain related transactions should be treated as taxable transactions for U.S. federal income tax purposes if it determines that any of the representations, assumptions or undertakings upon which the IRS private letter ruling or the opinion of counsel was based are false or have been violated. In addition, the IRS private letter ruling does not address all of the issues that are relevant to determining whether the Distribution of Alcoa, together with certain related transactions, qualifies as a transaction that is generally tax-free for U.S. federal income tax purposes, and the opinion of counsel represents the judgment of such counsel and is not binding on the IRS or any court and the IRS or a court may disagree with the conclusions in the opinion of counsel. Accordingly, notwithstanding receipt by Howmet of the IRS private letter ruling and the opinion of counsel, there can be no assurance that (i) the IRS will not assert that the Distribution of Alcoa and/or certain related transactions do not qualify for tax-free treatment for U.S. federal income tax purposes; or (ii) a court would not sustain such a challenge. In the event the IRS were to prevail with such challenge, Howmet, Alcoa Corporation and Howmet shareholders could be subject to significant U.S. federal income tax liability.

If the Distribution of Alcoa, together with certain related transactions, fails to qualify as a transaction that is generally tax-free, for U.S. federal income tax purposes, under Sections 355 and 368(a)(1)(D) of the Code, in general, for U.S. federal income tax purposes, Howmet would recognize taxable gain as if it had sold the Alcoa Corporation common stock in a taxable sale for its fair market value and Howmet shareholders who received Alcoa Corporation shares in the distribution would be subject to tax as if they had received a taxable distribution equal to the fair market value of such shares.

Under current U.S. federal income tax law, even if the Distribution of Alcoa, together with certain related transactions, otherwise qualifies for tax-free treatment under Sections 355 and 368(a)(1)(D) of the Code, the Distribution of Alcoa may nevertheless be rendered taxable to Howmet and its shareholders as a result of certain post-Distribution of Alcoa transactions, including certain acquisitions of shares or assets of Howmet or Alcoa Corporation. The possibility of rendering the Distribution of Alcoa taxable as a result of such transactions may limit Howmet’s ability to pursue certain equity issuances, strategic transactions or other transactions that would otherwise maximize the value of Howmet’s business. Under the Tax Matters Agreement that Howmet entered into with Alcoa Corporation, Alcoa Corporation may be required to indemnify Howmet against any additional taxes and related amounts resulting from (i) an acquisition of all or a portion of the equity securities or assets of Alcoa Corporation, whether by merger or otherwise (and regardless of whether Alcoa Corporation participated in or otherwise facilitated the acquisition), (ii) other actions or failures to act by Alcoa Corporation or (iii) any of Alcoa Corporation’s representations, covenants or undertakings contained in any of the Alcoa Inc. Separation Transaction-related agreements and documents or in any documents relating to the IRS private letter ruling and/or the opinion of counsel being incorrect or violated. However, the indemnity from Alcoa Corporation may be insufficient to protect Howmet against the full amount of such additional taxes or related liabilities, and Alcoa Corporation may be unable to satisfy its indemnification obligations fully. Moreover, even if Howmet ultimately succeeds in recovering from Alcoa Corporation any amounts for which Howmet is held liable, Howmet may be temporarily required to bear such losses. In addition, Howmet and Howmet’s subsidiaries may incur certain tax costs in connection with the Alcoa Inc. Separation Transaction, including tax costs resulting from separations in non-U.S. jurisdictions, which may be material. Each of these risks could negatively affect Howmet’s business, results of operations and financial condition.

Item 1B. Unresolved Staff Comments.

None.

Item 2. Properties.

Howmet’s principal office and corporate center is located at 201 Isabella Street, Suite 200, Pittsburgh, Pennsylvania 15212-5858.

Howmet leases some of its facilities; however, it is the opinion of management that the leases do not materially affect the continued use of the properties or the properties’ values.

Howmet believes that its facilities are suitable and adequate for its operations. Although no title examination of properties owned by Howmet has been made for the purpose of this report, the Company knows of no material defects in title to any such properties. See Notes A and O to the Consolidated Financial Statements in Part II, Item 8 of this Form 10-K.

Howmet has active plants and holdings in various geographic areas. See the table regarding the Company's principal facilities in Part I, Item 1. (Business).

Item 3. Legal Proceedings.

In the ordinary course of its business, Howmet is involved in a number of lawsuits and claims, both actual and potential. For a discussion of legal proceedings, see Note V to the Consolidated Financial Statements in Part II, Item 8, in addition to the matters set forth below.

Environmental Matters

Howmet is involved in proceedings under the Comprehensive Environmental Response, Compensation and Liability Act, also known as Superfund (“CERCLA”) or analogous state provisions regarding the usage, disposal, storage or treatment of hazardous substances at a number of sites in the U.S. The Company has committed to participate, or is engaged in negotiations with federal or state authorities relative to its alleged liability for participation, in clean-up efforts at several such sites. See the Environmental Matters section of Note V to the Consolidated Financial Statements for more information.

Other Matters

As previously reported, Howmet, its subsidiaries and former subsidiaries are defendants in lawsuits filed on behalf of persons alleging injury as a result of occupational or other exposure to asbestos. Howmet, its subsidiaries and former subsidiaries have numerous insurance policies over many years that provide coverage for asbestos related claims. The Company has significant insurance coverage and believes that Howmet’s reserves are adequate for its known asbestos exposure related liabilities. The costs of defense and settlement have not been and are not expected to be material to the results of operations, cash flows, and financial position of the Company.

Matters Related to Alcoa Corporation

Prior to the Alcoa Inc. Separation Transaction on November 1, 2016, the Company was known as Alcoa Inc. We have included the matters discussed below in which the Company remains party to proceedings relating to Alcoa Corporation. The Separation and Distribution Agreement, dated October 31, 2016, entered into between the Company and Alcoa Corporation in connection with the Alcoa Inc. Separation Transaction, provides for cross-indemnities between the Company and Alcoa Corporation for claims subject to indemnification. The Company does not expect any of such matters to result in a net claim against it.

St. Croix Proceedings

Red Dust Docket Cases, (St. Croix) f/k/a Abednego, Laurie L.A., et al. v. St. Croix Alumina, L.L.C., et al. On January 14, 2010, Alcoa Inc. was served with a multi-plaintiff action complaint involving several thousand individual persons claiming to be residents of St. Croix who are alleged to have suffered personal injury or property damage from Hurricane Georges or winds blowing material from the St. Croix Alumina, L.L.C. (“SCA”) facility on the island of St. Croix (U.S. Virgin Islands) since the time of the hurricane. This complaint, Abednego, et al. v. Alcoa, et al., was filed in the Superior Court of the Virgin Islands, St. Croix Division. Following an unsuccessful attempt by Alcoa Inc. and SCA to remove the case to federal court, the case has been lodged in the Superior Court. The complaint names as defendants the same entities that were sued in a February 1999 action arising out of the impact of Hurricane Georges on the island and added as a defendant the current owner of the alumina facility property.

On March 1, 2012, Alcoa Inc. was served with a separate multi-plaintiff action complaint involving approximately 200 individual persons alleging claims essentially identical to those set forth in the Abednego v. Alcoa complaint. This complaint, Abraham, et al. v. Alcoa, et al., was filed on behalf of plaintiffs previously dismissed in the federal court proceeding involving the original litigation over Hurricane Georges impacts. The matter was originally filed in the Superior Court of the Virgin Islands, St. Croix Division, on March 30, 2011.

Alcoa Inc. and other defendants in the Abraham and Abednego cases filed or renewed motions to dismiss each case in March 2012 and August 2012 following service of the Abraham complaint on Alcoa Inc. and remand of the Abednego complaint to

Table of Contents

Superior Court, respectively. By order dated August 10, 2015, the Superior Court dismissed plaintiffs’ complaints without prejudice to re-file the complaints individually, rather than as a multi-plaintiff filing. The order also preserves the defendants’ grounds for dismissal if new, individual complaints are filed. On July 7, 2017, the Court issued an order and associated memoranda on plaintiff’s multiple motions for extension of time to file the individual complaints. Following the court’s July 7, 2017 order, a total of 429 complaints were filed and accepted by the court by the deadline of July 30, 2017 (and consolidated into the Red Dust Claims docket (Master Case No.: SX-15-CV-620)). These complaints include claims of about 1,260 individual plaintiffs.

On November 5, 2018, notice of an order of reassignment was entered, transferring the claims to the newly created Complex Litigation Division of the Superior Court of the Virgin Islands, Division of St. Croix. On January 28, 2019, the plaintiffs filed a motion asking for a determination that expert testimony will not be required on the issue of causation, which defendants opposed. The Court has not ruled on that motion.

Overview

Our Business

Management Review of 2020 and Outlook for the Future

In 2020, Sales decreased 26% over 2019 primarily as a result of lower volumes in the commercial aerospace and commercial transportation markets driven by the impacts of COVID-19 and 737 MAX and 787 production declines along with a decrease in sales of $116 due to the divestiture of the forgings business in the United Kingdom in December 2019, all partially offset by 14% and 28% sales growth in the defense aerospace and industrial gas turbine markets, respectively, as well as favorable product pricing.

In the segments, Segment operating profit decreased 36% from 2019 due to lower volumes in the commercial aerospace and commercial transportation markets driven by the impacts of COVID-19 and 737 MAX and 787 production declines and unfavorable product mix, partially offset by favorable product pricing, net cost savings and 14% and 28% sales growth in the defense aerospace and industrial gas turbine markets, respectively.

Management continued its focus on liquidity and cash flows as well as improving its operating performance through cost reductions, streamlined organizational structures, margin enhancement, and profitable revenue generation. Management has continued its intensified focus on capital efficiency. This focus and the related results enabled Howmet to end 2020 with a solid financial position.

The following financial information reflects certain key highlights of Howmet’s 2020 results:

•Sales of $5,259 down 26% from 2019, with significant reductions in sales in commercial aerospace and commercial transportation markets, driven by COVID-19 and 737 MAX and 787 production declines;

•Net income from continuing operations of $211, or $0.48 per diluted share;

•Income from continuing operations before income taxes of $171, a decrease of $39, or 19%, from 2019;

•Total segment operating profit of $890, a decrease of $500, or 36%, from 2019(1);

•Cash provided from operations of $9; cash used for financing activities of $369; and cash provided from investing activities of $271;

•Cash on hand at the end of the year of $1,610; and

•Total debt of $5,075, primarily due to a decrease of $865 from 2019, reflecting repayments of $2,040 along with $20 of other debt, partially offset by issuance of debt during the second quarter of 2020 of $1,200 notes due 2025.

(1) See below in Results of Operations for the reconciliation of Total segment operating profit to Income from continuing operations before income taxes.

The Company rapidly executed on the separation plan that was announced during February 2019 with completion of the separation on April 1, 2020. The Company separated into two independent, publicly-traded companies, Howmet Aerospace Inc. and Arconic Corporation (the “Arconic Inc. Separation Transaction”). Howmet Aerospace is comprised of the Engineered Products and Forgings businesses (engine products, fastening systems, engineered structures, and forged wheels) and is listed under the stock ticker of “HWM.” Arconic Corporation is comprised of the former Global Rolled Products segment (global rolled products, aluminum extrusions, and building and construction systems) and is under the new company name Arconic Corporation, listed on the New York Stock Exchange under the symbol “ARNC.”

Results of Operations

Earnings Summary

Sales. Sales for 2020 were $5,259 compared with $7,098 in 2019, a decrease of $1,839, or 26%. The decrease was primarily a result of lower volumes in the commercial aerospace and commercial transportation markets driven by the impacts of

Table of Contents

COVID-19 and 737 MAX and 787 production declines along with a decrease in sales of $116 due to the divestiture of the forgings business in the U.K. in December 2019, all partially offset by growth in the defense aerospace and industrial gas turbine markets and favorable product pricing.

Sales for 2019 were $7,098 compared with $6,778 in 2018, an increase of $320, or 5%. The increase was primarily due to volume growth in aerospace, commercial transportation, and industrial end markets; and favorable pricing when fulfilling volume above contractual share and renewing contracts; partially offset by lower sales from the divestitures of forgings businesses in the United Kingdom (divested in December 2019) and Hungary (divested in December 2018); and unfavorable foreign currency movements.

Cost of Goods Sold (COGS). COGS as a percentage of Sales was 73.7% in 2020 compared with 73.5% in 2019. The increase was primarily due to the impact of COVID-19 and lower volumes, partially offset by net cost savings, favorable product pricing, intentional product exits, and the impairment of energy business assets of $10 in the second quarter of 2019. In 2019, the Company sustained a fire at a fasteners plant in France. Additionally, in mid-February 2020, a fire occurred at the Company's forged wheels plant located in Barberton, Ohio. The Company submitted insurance claims related to these plant fires and received partial settlements of $39 in 2020 compared to $25 in 2019, which were in excess of the insurance deductible. In 2020, the Company recorded charges of $41 related to plant fires compared to $26 in 2019. The downtime reduced production levels and affected productivity at the plants.

COGS as a percentage of Sales was 73.5% in 2019 compared with 75.4% in 2018. The decrease was primarily due to lower raw material costs; net costs savings; favorable product pricing; and costs incurred in 2018 that did not recur in 2019 related to settlements of certain customer claims, partially offset by an unfavorable product mix and the impairment of energy business assets of $10. Additionally, in 2019, the Company sustained a fire at a fasteners plant in France and recorded charges of $26 for higher operating costs, equipment and inventory damage, and repairs and cleanup costs. The Company submitted an insurance claim and received partial settlement of $25, which was in excess of its $10 insurance deductible. The insurance claim included $8 of margin not recognized from lost revenue due to the fire.

Selling, General Administrative, and Other Expenses (SG&A). SG&A expenses were $277, or 5.3% of Sales, in 2020 compared with $400, or 5.6% of Sales, in 2019. The decrease in SG&A of $123, or 31%, was primarily due to overhead cost reductions and lower net legal and other advisory costs related to Grenfell Tower of $20, partially offset by higher costs associated with the Arconic Inc. Separation Transaction through June 30, 2020 of $2.

SG&A expenses were $400, or 5.6% of Sales, in 2019 compared with $371, or 5.5% of Sales, in 2018. The increase in SG&A of $29, or 8%, was primarily due to costs associated with the Arconic Inc. Separation Transaction of $5 and higher annual incentive compensation accruals and executive compensation costs, partially offset by lower costs driven by overhead cost reductions and lower net legal and other advisory costs related to Grenfell Tower of $10, primarily due to insurance reimbursements.

Research and Development Expenses (R&D). R&D expenses were $17 in 2020 compared with $28 in 2019. The decrease of $11, or 39%, was primarily due to the continued consolidation of the Company's primary R&D facility in conjunction with ongoing cost reduction efforts.

R&D expenses were $28 in 2019 compared with $41 in 2018. The decrease of $13, or 32%, was primarily due to the consolidation of the Company's primary R&D facility in conjunction with ongoing cost reduction efforts.

Provision for Depreciation and Amortization (D&A). The provision for D&A was $279 in 2020 compared with $295 in 2019. The decrease of $16, or 5%, was primarily driven by asset impairments of the Disks long-lived assets group during the second quarter of 2019 (see Notes O and P to the Consolidated Financial Statements in Part II, Item 8. (Financial Statements and Supplementary Data) of this Form 10-K) and the impact of divestitures as well as lower corporate software amortization and research center depreciation, which were partially offset by increased Forged Wheels D&A due to the capacity expansion in Hungary, capacity expansions at two U.S. facilities and an additional $6 D&A related to the Barberton fire.

The provision for D&A was $295 in 2019 compared with $314 in 2018. The decrease of $19, or 6% was primarily due to the impact of divestitures, as well as asset impairments of the Disks long-lived asset group during the second quarter of 2019 (see Note O and P to the Consolidated Financial Statements in Part II, Item 8. (Financial Statements and Supplementary Data) of this Form 10-K).

Restructuring and Other Charges. Restructuring and other charges were $182 in 2020 compared with $582 in 2019 and $163 in 2018.

Restructuring and other charges in 2020 consisted primarily of a $113 charge for layoff costs, a $74 charge for U.K. and U.S. pension plans' settlement accounting; a $5 post-closing adjustment related to the sale of the Company’s U.K. forgings business; a $5 charge for impairment of assets associated with an agreement to sell an aerospace components business in the U.K that did not occur and the business was returned to held for use; $5 charge related to the impairment of a cost method investment, which were partially offset by a benefit of $21 related to the reversal of a number of prior period programs;

Restructuring and other charges in 2019 consisted primarily of a $428 charge for impairment of the Disks long-lived asset group; a $69 charge for layoff costs; a $46 charge for impairment of assets associated with an agreement to sell the U.K. forgings business; a $14 charge for impairment of properties, plants, and equipment related to the Company’s primary research and development facility; a $13 loss on sale of assets primarily related to a small additive business; a $12 charge for other exit costs from lease terminations primarily related to the exit of the corporate aircraft; a $9 settlement accounting charge for U.S. pension plans; a $5 charge for impairment of a cost method investment; and a $7 charge for other exit costs; which were partially offset by a benefit of $16 related to the elimination of the life insurance benefit for the U.S. salaried and non-bargaining hourly retirees of the Company and its subsidiaries.

Restructuring and other charges in 2018 consisted primarily of a $96 charge for pension plan settlement accounting; a $23 charge for pension curtailment; a $43 loss on sale of a Hungary forgings business; a $18 charge for layoff costs; a $12 charge for contract termination costs and asset impairments associated with the shutdown of a facility in Acuna, Mexico; which were offset partially by a $28 postretirement curtailment benefit.

See Note E to the Consolidated Financial Statements in Part II, Item 8. (Financial Statements and Supplementary Data) of this Form 10-K.

Interest Expense. Interest expense was $381 in 2020 compared with $338 in 2019. The increase of $43, or 13%, was primarily due to premiums paid on the early redemption of debt of $59 which was offset by lower debt outstanding in 2020 driven by the early redemption of $1,000, $889 and $151 of the principal amount of the 6.150% Notes, 5.400% Notes due in 2021 and 5.870% Notes due in 2022, respectively, in April and May 2020, which was offset by the issuance on April 24, 2020 of the 6.875% Notes due 2025 in the aggregate principal amount of $1,200.

Interest expense was $338 in 2019 compared with $377 in 2018. The decrease of $39, or 10%, was primarily due to lower debt outstanding, driven by the repayment of the aggregate outstanding principal amount of the 1.63% Convertible Notes of approximately $403 on October 15, 2019, as well as costs incurred of $19 in 2018 related to the premium paid on the early redemption of the Company’s then outstanding 5.72% Senior Notes due in 2019 that did not recur in 2019.

On January 15, 2021, the Company completed the early redemption of all of the remaining $361 aggregate principal amount of the 5.400% Notes due in April 2021 (the "5.400% Notes") as well as $5 in accrued interest. The redemption of these 5.400% Notes will save approximately $5 in Interest expense, net in the first quarter of 2021 and $19 annually.

Other Expense (Income), Net. Other expense (income), net was $74 in 2020 compared with $31 in 2019. The increase in expense of $43 was primarily driven by the write-off of an indemnification receivable related to a Spanish tax reserve reflecting Alcoa Corporation's 49% share and Arconic Corporation's 33.66% share of a Spanish tax reserve of $53 and lower interest income of $19, which were partially offset by lower deferred compensation expense of $14 and favorable foreign currency movements of $16.

Other expense (income), net was $31 in 2019 compared with Other expense (income), net of $(30) in 2018. The increase in Other expense, net of $61 was primarily due to an increase in deferred compensation expense of $32 and the benefit recognized in 2018 from establishing a tax indemnification receivable reflecting Alcoa Corporation’s 49% share of a Spanish tax reserve of $29.

Income Taxes. Howmet’s effective tax rate was 23.4% (benefit on pre-tax income) in 2020 compared with the U.S. federal statutory rate of 21%. The effective rate differs from the U.S. federal statutory rate primarily as a result of a $64 benefit related to the release of an income tax reserve following a favorable Spanish tax case decision, a $30 benefit related to the recognition of a previously uncertain U.S. tax position, and a $30 benefit for a U.S. tax law change related to the issuance of final regulations that provide for an exclusion of certain high-taxed foreign earnings from the calculation of Global Intangible Low-Taxed Income ("GILTI"), partially offset by U.S. tax on foreign earnings, $8 of charges related to the remeasurement of deferred tax balances as a result of the Arconic Inc. Separation Transaction, the tax impact of $49 of nondeductible loss related to the reversal of indemnification receivables associated with the favorable Spanish tax case decision, and the tax impact of other nondeductible expenses.

Howmet’s effective tax rate was 40.0% (provision on pre-tax income) in 2019 compared with the U.S. federal statutory rate of 21%. The effective rate differs from the U.S. federal statutory rate primarily as a result of foreign income taxed in higher rate

Table of Contents

jurisdictions and subject to U.S. taxes including GILTI, foreign losses with no tax benefit, and other nondeductible expenses, partially offset by a $24 benefit associated with the deduction of foreign taxes that were previously claimed as a U.S. foreign tax credit, and a $12 benefit for a foreign tax rate change.

Howmet’s effective tax rate was 27.8% (provision on pre-tax income) in 2018 compared with the U.S. federal statutory rate of 21%. The effective tax rate differs from the U.S. federal statutory rate primarily as a result of a $60 charge to establish a tax reserve in Spain, a $59 net charge resulting from the Company's finalized analysis of the U.S. Tax Cuts and Jobs Act of 2017 (the "2017 Act"), and foreign income taxed in higher rate jurisdictions and subject to U.S. taxes including GILTI, partially offset by a $74 benefit related to the reversal of a foreign recapture obligation, a $38 benefit to reverse a foreign tax reserve that was effectively settled, and a $10 benefit for the release of U.S. valuation allowances.

Howmet anticipates that the effective tax rate in 2021 will be between 26.5% and 28.5%. However, changes in the current economic environment, tax legislation or rate changes, currency fluctuations, ability to realize deferred tax assets, movements in stock price impacting tax benefits or deficiencies on stock-based payment awards, and the results of operations in certain taxing jurisdictions may cause this estimated rate to fluctuate.

Net Income from Continuing Operations. Net income from continuing operations was $211, or $0.48 per diluted share, for 2020 compared to $126, or $0.27 per diluted share, in 2019. The increase in results of $85, or 67%, was primarily due to the non-recurring 2019 impact of the $428 charge for impairment of the Disks long-lived asset group included in Restructuring and other charges, a decrease of $123 due to lower SG&A costs, favorable product pricing, and a net $10 related to the settlement of the Spanish corporate income tax audit, partially offset by a decrease in volumes in the commercial aerospace and commercial transportation markets, the impact of COVID-19, and an increase in premiums paid on the early redemption of debt of $59.

Net income from continuing operations was $126, or $0.27 per diluted share, for 2019 compared to $309, or $0.63 per diluted share, for 2018. The decrease in results of $183, or 59%, was primarily due to higher Restructuring charges primarily due to the non-recurring 2019 impact of the $428 charge for impairment of the Disks long-lived asset group, higher SG&A costs related primarily to annual incentive compensation accruals and executive compensation costs, higher Other expense, net due to an increase in deferred compensation expense, and the benefit recognized in 2018 from establishing a tax indemnification receivable reflecting Alcoa Corporation’s 49% share of a Spanish tax reserve of $29 that did not recur in 2019, partially offset by volume growth, favorable product pricing, net cost savings, lower D&A due to the impact of divestitures as well as asset impairments related to the Disks long-lived asset group, lower Interest expense due to lower debt outstanding and costs incurred of $19 in 2018 related to the premium paid on the early redemption of debt that did not recur in 2019, and lower Income taxes primarily as a result of a benefit related to a U.S. tax election which caused the deemed liquidation of a foreign subsidiary’s assets into its U.S. tax parent.

Net Income. Net income was $261 for 2020 composed of $211 of income from continuing operations and $50 from discontinued operations, or $0.48 and $0.11 per diluted share, respectively.

Net income was $470 for 2019 composed of $126 of income from continuing operations and $344 from discontinued operations, or $0.27 and $0.76 per diluted share, respectively.

Net income was $642 for 2018 composed of $309 of income from continuing operations and $333 from discontinued operations, or $0.63 and $0.67 per diluted share, respectively.

See details of discontinued operations in Note C to the Consolidated Financial Statements in Part II, Item 8. (Financial Statements and Supplementary Data) of this Form 10-K.

Segment Information

The Company’s operations consist of four worldwide reportable segments: Engine Products, Fastening Systems, Engineered Structures and Forged Wheels. Segment performance under Howmet’s management reporting system is evaluated based on a number of factors; however, the primary measure of performance is Segment operating profit. Howmet’s definition of Segment operating profit is Operating income excluding Special items. Special items include Restructuring and Other charges and Impairment of Goodwill. Segment operating profit may not be comparable to similarly titled measures of other companies. Differences between segment totals and consolidated Howmet are in Corporate.

In the second quarter of 2020, the Company realigned its operations consistent with how the Co-Chief Executive Officers assess operating performance and allocating capital in conjunction with the Arconic Inc. Separation Transaction (see Note C to the Consolidated Financial Statements in Part II Item 8 of this Form 10-K). Prior period financial information has been recast to conform to current year presentation.

The Company produces aerospace engine parts and components and aerospace fastening systems for Boeing 737 MAX airplanes. In late December 2019, Boeing announced a temporary suspension of production of the 737 MAX airplanes. This decline in production had a negative impact on sales and segment operating profit in the Engine Products, Fastening Systems and Engineered Structures segments for the full year ended December 31, 2020. While regulatory authorities in the United

Table of Contents

States and certain other jurisdictions lifted grounding orders beginning in late 2020, our sales could continue to be negatively affected from the residual impacts of the 737 MAX grounding.

Income from continuing operations before income taxes totaled $171 in 2020, $210 in 2019, and $428 in 2018. Segment operating profit for all reportable segments totaled $890 in 2020, $1,390 in 2019, and $1,105 in 2018. The following information provides Sales and Segment operating profit for each reportable segment for each of the three years in the period ended December 31, 2020. See below for the reconciliation of Income from continuing operations before income taxes to Total segment operating profit.

Total segment operating profit is a non-GAAP financial measure. Management believes that this measure is meaningful to investors because management reviews the operating results of the segments of the Company excluding Corporate results.

See Restructuring and Other Charges, Interest Expense, and Other Expense (Income), Net, discussions above under Results of Operations for reference.

Corporate expense decreased $147, or 64%, in 2020 compared with 2019 primarily due to lower annual incentive compensation accruals and executive compensation costs, lower costs driven by overhead cost reductions, lower contract services and outsourcing costs; lower research and development expenses; and lower net legal and other advisory costs along with costs incurred in 2019 that did not recur in 2020, including the impacts of facility fires, net of insurance of $6 and collective bargaining agreement negotiation costs of $9. Costs associated with the Arconic Inc. Separation Transaction of $7, were an increase of $2 compared to 2019.

Corporate expense increased $62, or 37%, in 2019 compared with 2018 primarily due to costs associated with the Arconic Inc. Separation Transaction of $5; higher annual incentive compensation accruals and executive compensation costs; net impacts associated with a fire at a fasteners plant of $9 (net of insurance reimbursements); and collective bargaining agreement negotiation costs of $9; partially offset by costs incurred in 2018 that did not recur in 2019 related to settlements of certain customer claims of $38; lower costs driven by overhead cost reductions; lower research and development expenses; and lower net legal and other advisory costs related to Grenfell Tower of $10.

Liquidity and Capital Resources

Howmet maintains a disciplined approach to cash management and strengthening of its balance sheet. Management continued to focus on actions to improve Howmet’s cost structure and liquidity, providing the Company with the ability to operate effectively. Such actions included procurement efficiencies and overhead rationalization to reduce costs, working capital initiatives, and maintaining a sustainable level of capital expenditures.

Cash provided from operations and financing activities is expected to be adequate to cover Howmet's operational and business needs over the next 12 months. For an analysis of long-term liquidity, see Contractual Obligations and Off-Balance Sheet Arrangements below.

At December 31, 2020, cash and cash equivalents of Howmet were $1,610, of which $253 was held by Howmet's non-U.S. subsidiaries. If the cash held by non-U.S. subsidiaries were to be repatriated to the U.S., the company does not expect there to be additional material income tax consequences.

The cash flows related to Arconic Corporation have not been segregated and are included in the Statement of Consolidated Cash Flows for all periods prior to the Arconic Inc. Separation Transaction.

During 2020 the Company identified a misclassification in the presentation of changes in accounts payable and capital expenditures in its previously issued Statement of Consolidated Cash Flows, and has revised its Statement of Consolidated Cash Flows for 2019. See Note A to the Consolidated Financial Statements in Part II, Item 8 of this Form 10-K for additional detail.

Operating Activities

Cash provided from operations in 2020 was $9 compared with $461 in 2019 and $217 in 2018.

The decrease in cash used for operations of $452, or 98%, between 2020 and 2019 was primarily due to lower operating results of $874, partially offset by lower working capital of $355 and lower noncurrent assets of $46, noncurrent liabilities of $10 and pension contributions of $11. The components of the change in working capital included favorable changes in receivables of $739, inventories of $77, and taxes, including income taxes of $100, offset by accounts payable of $380, accrued expenses of $175 and prepaid expenses and other current assets of $6.

The increase of $244, or 112%, between 2019 and 2018 was primarily due to higher operating results of $279 and lower pension contributions of $30 and noncurrent assets of $13, partially offset by higher working capital of $57 and noncurrent liabilities of $21. The components of the change in working capital included unfavorable changes in accounts payable of $340 and taxes, including income taxes of $106, partially offset by favorable changes in receivables of $165 accrued expenses of $148, inventories of $71 and prepaid expenses and other current assets of $5.

Financing Activities

Cash used for financing activities was $369 in 2020 compared with $1,568 in 2019 and $649 in 2018.

The use of cash in 2020 was primarily related to the repayments on borrowings under certain revolving credit facilities (see below) and repayments on debt, primarily the aggregate outstanding principal amount of the 6.15% Notes due 2020 of approximately $2,040 (see Note R to the Consolidated Financial Statements in Part II, Item 8. Financial Statements and Supplementary Data), cash distributed to Arconic Corporation at the Arconic Inc. Separation Transaction of $500, repurchase of common stock of $73 (see Note J to the Consolidated Financial Statements in Part II, Item 8. Financial Statements and Supplementary Data), debt issuance costs of $61, premiums paid on the redemption of debt of $59, and dividends paid to shareholders of $11. These items were partially offset by long-term debt issuance of $2,400 (of which $1,200 went with Arconic Corporation at the Arconic Inc. Separation Transaction) and proceeds from the exercise of employee stock options of $33.

The use of cash in 2019 was primarily related to the repurchase of $1,150 of common stock (see Note J to the Consolidated Financial Statements in Part II, Item 8. Financial Statements and Supplementary Data); repayments on borrowings under certain revolving credit facilities (see below) and repayments on debt, primarily the aggregate outstanding principal amount of the 1.63% Convertible Notes of approximately $403 (see Note R to the Consolidated Financial Statements in Part II, Item 8. (Financial Statements and Supplementary Data)); and dividends paid to shareholders of $57. These items were partially offset by proceeds from the exercise of employee stock options of $56.

The use of cash in 2018 was principally the result of $1,103 in repayments on borrowings under certain revolving credit facilities (see below) and repayments on debt, primarily related to the early redemption of the then remaining outstanding 5.72% Notes due in 2019 (see Note R to the Consolidated Financial Statements in Part II, Item 8. (Financial Statements and

Supplementary Data of this Form 10-K)) and $119 in dividends to shareholders. These items were partially offset by $600 in additions to debt, primarily from borrowings under certain revolving credit facilities.

The Company maintains a Five-Year Revolving Credit Agreement (the “Credit Agreement”) with a syndicate of lenders and issuers named therein. On June 26, 2020, the Company entered into an amendment to its Credit Agreement to modify certain terms which provided relief from its existing financial covenant through December 31, 2021 and reduced total commitment available from $1,500 to $1,000. See Note R to the Consolidated Financial Statements in Part II, Item 8. Financial Statements and Supplementary Data of this Form 10-K. In addition to the Credit Agreement, the Company has other credit facilities from time to time.

The Company may in the future repurchase additional portions of its debt or equity securities from time to time, in either the open market or through privately negotiated transactions, in accordance with applicable SEC and other legal requirements. The timing, prices, and sizes of purchases depend upon prevailing trading prices, general economic and market conditions, and other factors, including applicable securities laws.

The Company’s costs of borrowing and ability to access the capital markets are affected not only by market conditions but also by the short- and long-term debt ratings assigned to the Company by the major credit rating agencies.

Investing Activities

Cash provided from investing activities was $271 in 2020 compared with $528 in 2019 and $565 in 2018.

The source of cash in 2020 was primarily cash receipts from sold receivables of $422 and proceeds from the sale a rolling mill business in Itapissuma, Brazil for $50 and a hard alloy extrusions plant in South Korea for $62 which were related to Arconic Corporation (see Notes C and U to the Consolidated Financial Statements in Part II, Item 8 (Financial Statements and Supplementary Data)), partially offset by capital expenditures of $267.

The source of cash in 2019 was primarily cash receipts from sold receivables of $995, proceeds from the sale of assets and businesses of $103 primarily from the sale of a forgings business in the U.K. for $64 and the sale of inventories and properties, plants, and equipment related to a small energy business for $13 as well as contingent consideration of $20 related to the sale of the Texarkana, Texas rolling mill (which was part of Arconic Corporation at the Arconic Inc. Separation Transaction) (see Notes C and U to the Consolidated Financial Statements in Part II, Item 8. (Financial Statements and Supplementary Data)), and the sale of fixed income securities of $73, partially offset by capital expenditures of $641, including expansion of a wheels plant in Hungary, expansion of aerospace airfoils capacity in the United States, and transition of the Tennessee plant to industrial production (which was part of Arconic Corporation at the Arconic Inc. Separation Transaction).

The source of cash in 2018 was primarily cash receipts from sold receivables of $1,016 and proceeds from the sale of the Texarkana, Texas rolling mill and cast house of $302 which was related to Arconic Corporation, partially offset by capital expenditures of $768, including the horizontal heat treat furnace at the Davenport, Iowa plant (which was part of Arconic Corporation at the Arconic Inc. Separation Transaction) and an expansion of a wheels plant in Székesfehérvár, Hungary.

Contractual Obligations and Off-Balance Sheet Arrangements

Contractual Obligations

Howmet is required to make future payments under various contracts, including long-term purchase obligations, financing arrangements, and lease agreements. Howmet also has commitments to fund its pension plans, provide payments for other postretirement benefit plans, and fund capital projects.

As of December 31, 2020, a summary of Howmet’s outstanding contractual obligations is as follows (these contractual obligations are grouped in the same manner as they are classified in the Statement of Consolidated Cash Flows in order to provide a better understanding of the nature of the obligations and to provide a basis for comparison to historical information):

Obligations for Operating Activities

Raw material purchase obligations consist mostly of aluminum, cobalt, nickel, and various other metals with expiration dates ranging from less than one year to five years. Many of these purchase obligations contain variable pricing components, and, as a result, actual cash payments may differ from the estimates provided in the preceding table. The Company generally passes through metal costs in customer contracts with limited exceptions. In connection with the Arconic Inc. Separation Transaction, the Company entered into several agreements with Arconic Corporation that govern the relationship between the Company and Arconic Corporation following the separation, including Raw Material Supply Agreements.

Operating leases represent multi-year obligations for certain land and buildings, plant equipment, vehicles, and computer equipment.

Interest related to total debt is based on interest rates in effect as of December 31, 2020 and is calculated on debt with maturities that extend to 2042.

Estimated minimum required pension funding and postretirement benefit payments are based on actuarial estimates using current assumptions for discount rates, long-term rate of return on plan assets, and health care cost trend rates, among others. It is Howmet’s policy to fund amounts for pension plans sufficient to meet the minimum requirements set forth in applicable country benefits laws and tax laws. Periodically, Howmet contributes additional amounts as deemed appropriate. The estimates reported in the preceding table include amounts sufficient to meet the minimum required. Howmet has determined that it is not practicable to present pension funding and other postretirement benefit payments beyond 2024 and 2029, respectively.

Layoff and other restructuring payments to be paid within one year primarily relate to severance costs, special layoff benefit payments, and lease termination costs.

Uncertain tax positions taken or expected to be taken on an income tax return may result in additional payments to tax authorities. The amount in the preceding table includes interest and penalties accrued related to such positions as of December 31, 2020. The total amount of uncertain tax positions is included in the “Thereafter” column as the Company is not able to reasonably estimate the timing of potential future payments. If a tax authority agrees with the tax position taken or expected to be taken or the applicable statute of limitations expires, then additional payments will not be necessary.

Obligations for Financing Activities

Howmet has historically paid quarterly dividends on its preferred and common stock. Including dividends on preferred stock, the Company paid $11 in dividends to shareholders during 2020. Because all dividends are subject to approval by Howmet’s Board of Directors, amounts are not included in the preceding table unless such authorization has occurred. As of December 31, 2020, there were 432,906,377 shares of outstanding common stock and 546,024 shares of outstanding Class A preferred stock. In 2020, the preferred stock dividend was $3.75 per share. Dividend of $0.02 per share on the Company's common stock was paid in the first quarter of 2020. As the duration of the COVID-19 pandemic is uncertain, the Company is taking a series of actions to address the financial impact, including the suspension of dividends on common stock in April 2020. See Part I, Item 1A (Risk Factors).

Obligations for Investing Activities

Capital projects in the preceding table only include amounts approved by management as of December 31, 2020. Funding levels may vary in future years based on anticipated construction schedules of the projects. It is expected that significant expansion projects will be funded through various sources, including cash provided from operations. Total capital expenditures are anticipated to be approximately 4% of sales in 2021.

Off-Balance Sheet Arrangements

At December 31, 2020, the Company had outstanding bank guarantees related to tax matters, outstanding debt, workers’ compensation, environmental obligations, energy contracts, and customs duties, among others. The total amount committed under these guarantees, which expire at various dates between 2021 and 2040 was $44 at December 31, 2020.

Pursuant to the Separation and Distribution Agreement between the Company and Alcoa Corporation, the Company is required to provide certain guarantees for Alcoa Corporation, which had a combined fair value of $12 and $9 at December 31, 2020 and 2019, respectively, and were included in Other noncurrent liabilities and deferred credits on the accompanying Consolidated Balance Sheet. For a long-term supply agreement, the Company is required to provide a guarantee up to an estimated present value amount of approximately $1,398 and $1,353 at December 31, 2020 and December 31, 2019, respectively, in the event of an Alcoa Corporation payment default. This guarantee expires in 2047. For this guarantee, subject to its provisions, the Company is secondarily liable in the event of a payment default by Alcoa Corporation. The Company currently views the risk of an Alcoa Corporation payment default on its obligations under the contract to be remote. In December 2019, Arconic Inc. entered into a one-year insurance policy with a limit of $80 relating to the long-term energy supply agreement. The premium is expected to be paid by Alcoa Corporation. In December 2020, a surety bond with a limit of $80 relating to the long-term energy supply agreement was obtained by Alcoa Corporation to protect Howmet's obligation. This surety bond will be renewed on an annual basis.

Howmet has outstanding letters of credit primarily related to workers’ compensation, environmental obligations, and leasing obligations. The total amount committed under these letters of credit, which automatically renew or expire at various dates, mostly in 2021, was $105 at December 31, 2020.

Pursuant to the Separation and Distribution Agreements between the Company and Arconic Corporation and between the Company and Alcoa Corporation, the Company is required to retain letters of credit of $53 that had previously been provided related to the Company, Arconic Corporation, and Alcoa Corporation workers’ compensation claims which occurred prior to the respective separation transactions of April 1, 2020 and November 1, 2016. Arconic Corporation and Alcoa Corporation workers’ compensation claims and letter of credit fees paid by the Company are being proportionally billed to and are being reimbursed by Arconic Corporation and Alcoa Corporation. Also, the Company was required to provide letters of credit for certain Arconic Corporation environmental obligations and, as a result, the Company has $29 of outstanding letters of credit relating to liabilities (which are included in the $105 in the above paragraph). $13 of these outstanding letters of credit are pending cancellation and will be deemed cancelled once returned by the beneficiary. Arconic Corporation has issued surety bonds to cover these environmental obligations. Arconic Corporation is being billed for these letter of credit fees paid by the Company and will reimburse the Company for any payments made under these letters of credit.

Howmet has outstanding surety bonds primarily related to tax matters, contract performance, workers’ compensation, environmental-related matters, and customs duties. The total amount committed under these surety bonds, which expire at various dates, primarily in 2021, was $43 at December 31, 2020.

Pursuant to the Separation and Distribution Agreements between the Company and Arconic Corporation and between the Company and Alcoa Corporation, the Company was required to provide surety bonds of $26 (which are included in the $43 in the above paragraph) that had previously been provided, related to the Company, Arconic Corporation and Alcoa Corporation workers’ compensation claims which occurred prior to the respective separation transactions of April 1, 2020 and November 1, 2016. Arconic Corporation and Alcoa Corporation workers’ compensation letters of credit and surety bond fees paid by the Company are being proportionally billed to and are being reimbursed by Arconic Corporation and Alcoa Corporation.

Critical Accounting Policies and Estimates

The preparation of the Consolidated Financial Statements in accordance with accounting principles generally accepted in the United States of America requires management to make certain judgments, estimates, and assumptions regarding uncertainties that affect the amounts reported in the Consolidated Financial Statements and disclosed in the accompanying Notes. These estimates are based on historical experience and, in some cases, assumptions based on current and future market experience, including considerations relating to the impact of COVID-19. The impact of COVID-19 is rapidly changing and of unknown duration and macroeconomic impact and as a result, these considerations remain highly uncertain. Areas that require significant judgments, estimates, and assumptions include the testing of goodwill, other intangible assets, and properties, plants, and equipment for impairment; estimating fair value of businesses acquired or divested; pension plans and other postretirement benefits obligations; stock-based compensation; and income taxes.

Management uses historical experience and all available information to make these judgments, estimates, and assumptions, and actual results may differ from those used to prepare the Company’s Consolidated Financial Statements at any given time. Despite these inherent limitations, management believes that Management’s Discussion and Analysis of Financial Condition and Results of Operations and the Consolidated Financial Statements and accompanying Notes provide a meaningful and fair perspective of the Company.

A summary of the Company’s significant accounting policies is included in Note A to the Consolidated Financial Statements. Management believes that the application of these policies on a consistent basis enables the Company to provide the users of the Consolidated Financial Statements with useful and reliable information about the Company’s operating results and financial condition.

Goodwill. Goodwill is not amortized; instead, it is reviewed for impairment annually (in the fourth quarter) or more frequently if indicators of impairment exist or if a decision is made to sell or realign a business. A significant amount of judgment is involved in determining if an indicator of impairment has occurred. Such indicators may include deterioration in general economic conditions, negative developments in equity and credit markets, adverse changes in the markets in which an entity operates, increases in input costs that have a negative effect on earnings and cash flows, or a trend of negative or declining cash flows over multiple periods, among others. The fair value that could be realized in an actual transaction may differ from that used to evaluate the impairment of goodwill.

Goodwill is allocated among and evaluated for impairment at the reporting unit level, which is defined as an operating segment or one level below an operating segment. Howmet had four reporting units (Engine Products, Fastening Systems, Engineered Structures, and Forged Wheels) for 2020.

In reviewing goodwill for impairment, an entity has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not (greater than 50%) that the estimated fair value of a reporting unit is less than its carrying amount. If an entity elects to perform a qualitative assessment and determines that an impairment is more likely than not, the entity is then required to perform the quantitative impairment test (described below), otherwise no further analysis is required. An entity also may elect not to perform the qualitative assessment and, instead, proceed directly to the quantitative impairment test. The ultimate outcome of the goodwill impairment review for a reporting unit should be the same whether an entity chooses to perform the qualitative assessment or proceeds directly to the quantitative impairment test.

The Company determines annually, based on facts and circumstances, which of its reporting units will be subject to the qualitative assessment. For those reporting units where a qualitative assessment is either not performed or for which the conclusion is that an impairment is more likely than not, a quantitative impairment test will be performed. Howmet’s policy is that a quantitative impairment test be performed for each reporting unit at least once during every three-year period.

Under the qualitative assessment, various events and circumstances (or factors) that would affect the estimated fair value of a reporting unit are identified (similar to impairment indicators above). These factors are then classified by the type of impact they would have on the estimated fair value using positive, neutral, and adverse categories based on current business conditions. Additionally, an assessment of the level of impact that a particular factor would have on the estimated fair value is determined using high, medium, and low weighting. Furthermore, management considers the results of the most recent quantitative impairment test completed for a reporting unit and compares the weighted average cost of capital ("WACC") between the current and prior years for each reporting unit.

Table of Contents

reporting units is less than its carrying value. As a result of this assessment, the Company performed a quantitative impairment test in the first quarter for the Engineered Structures reporting unit and concluded that though the margin between the fair value of the reporting unit and carrying value had declined from approximately 60% to approximately 15%, it was not impaired. Consistent with prior practice, a discounted cash flow model was used to estimate the current fair value of the reporting unit. The significant assumptions and estimates utilized to determine fair value were developed utilizing current market and forecast information reflecting the disruption in demand that has had and is expected to have a negative impact on the Company’s global sales in the aerospace industry. During the second and third quarters of 2020, there were no indicators of impairment identified for the Engineered Structures reporting unit.

Under the quantitative impairment test, the evaluation of impairment involves comparing the current fair value of each reporting unit to its carrying value, including goodwill. Howmet uses a discounted cash flow ("DCF") model to estimate the current fair value of its reporting units when testing for impairment, as management believes forecasted cash flows are the best indicator of such fair value. A number of significant assumptions and estimates are involved in the application of the DCF model to forecast operating cash flows, including sales growth, production costs, capital spending, and discount rate. Most of these assumptions vary significantly among the reporting units. Cash flow forecasts are generally based on approved business unit operating plans for the early years and historical relationships in later years. The WACC rate for the individual reporting units is estimated with the assistance of valuation experts. Howmet would recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value without exceeding the total amount of goodwill allocated to that reporting unit.

Properties, Plants, and Equipment and Other Intangible Assets. Properties, plants, and equipment and Other intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets (asset group) may not be recoverable. Recoverability of assets is determined by comparing the estimated undiscounted net cash flows of the operations related to the assets (asset group) to their carrying amount. An impairment loss would be recognized when the carrying amount of the assets (asset group) exceeds the estimated undiscounted net cash flows. The amount of the impairment loss to be recorded is measured as the excess of the carrying value of the assets (asset group) over their fair value, with fair value determined using the best information available, which generally is a DCF model. The determination of what constitutes an asset group, the associated estimated undiscounted net cash flows, and the estimated useful lives of the assets also require significant judgments.

During the second quarter of 2019, the Company updated its five-year strategic plan and determined that there was a decline in the forecasted financial performance for the Disks asset group within the Engine Products and Forgings segment at that time. As such, the Company evaluated the recoverability of the Disks asset group long-lived assets by comparing the carrying value to the undiscounted cash flows of the Disks asset group. The carrying value exceeded the undiscounted cash flows and therefore the Disks asset group long-lived assets were deemed to be impaired. The impairment charge was measured as the amount of carrying value in excess of fair value of the long-lived assets, with fair value determined using a DCF model and a combination of sales comparison and cost approach valuation methods including an estimate for economic obsolescence. The impairment charge of $428, of which $247 and $181 related to the Engine Products and Engineered Structures segments, respectively, which was recorded in the second quarter of 2019, impacted properties, plants, and equipment; intangible assets; and certain other noncurrent assets by $198, $197, and $33, respectively. The impairment charge was recorded in Restructuring and other charges in the Statement of Consolidated Operations.

Discontinued Operations and Assets Held for Sale. The fair values of all businesses to be divested are estimated using accepted valuation techniques such as a DCF model, valuations performed by third parties, earnings multiples, or indicative bids, when available. A number of significant estimates and assumptions are involved in the application of these techniques, including the forecasting of markets and market share, sales volumes and prices, costs and expenses, and multiple other factors. Management considers historical experience and all available information at the time the estimates are made; however, the fair value that is ultimately realized upon the divestiture of a business may differ from the estimated fair value reflected in the Consolidated Financial Statements.

Pension and Other Postretirement Benefits. Liabilities and expenses for pension and other postretirement benefits are determined using actuarial methodologies and incorporate significant assumptions, including the interest rate used to discount the future estimated liability, the expected long-term rate of return on plan assets, and several assumptions relating to the employee workforce (health care cost trend rates, retirement age, and mortality).

The interest rate used to discount future estimated liabilities for the U.S. is determined using a Company-specific yield curve model (above-median) developed with the assistance of an external actuary, while both the U.K. and Canada utilize models

Table of Contents

developed by the respective actuary. The cash flows of the plans’ projected benefit obligations are discounted using a single equivalent rate derived from yields on high quality corporate bonds, which represent a broad diversification of issuers in various sectors, including finance and banking, industrials, transportation, and utilities, among others. The yield curve model parallels the plans’ projected cash flows, which have a global average duration of 12 years. The underlying cash flows of the bonds included in the model exceed the cash flows needed to satisfy the Company’s plans’ obligations multiple times. In 2020, 2019, and 2018, the discount rate used to determine benefit obligations for pension and other postretirement benefit plans was 2.40%, 3.00%, and 4.00%, respectively. The impact on the liabilities of a change in the discount rate of 1/4 of 1% would be approximately $90 and either a charge or credit of approximately $1 to earnings in the following year.

The expected long-term rate of return on plan assets is generally applied to a five-year market-related value of plan assets (a fair value at the plan measurement date is used for certain non-U.S. plans). The process used by management to develop this assumption is one that relies on a combination of historical asset return information and forward-looking returns by asset class. As it relates to historical asset return information, management focuses on various historical moving averages when developing this assumption. While consideration is given to recent performance and historical returns, the assumption represents a long-term, prospective return. Management also incorporates expected future returns on current and planned asset allocations using information from various external investment managers and consultants, as well as management’s own judgment.

For 2020, 2019, and 2018, management used 6.00%, 5.60%, and 5.90%, respectively, as its expected long-term rate of return on plan assets, which was based on the prevailing and planned strategic asset allocations, as well as estimates of future returns by asset class. These rates fell within the respective range of the 20-year moving average of actual performance and the expected future return developed by asset class. For 2021, management anticipates that 6.00% will be the expected long-term rate of return for the plan assets. A change in the assumption for the expected long-term rate of return on plan assets of 1/4 of 1% would impact earnings by approximately $4 for 2021.

In 2020, a net loss of $46 (after-tax) was recorded in other comprehensive loss, primarily due to the decrease in the discount rate, partially offset by the plan asset performance that was greater than expected, and by amortization of actuarial losses. After adjusting for the impact of Arconic Corporation's obligation, the net pension and other postretirement benefit obligation decreased less than 2% during 2020. In 2019, a net loss of $388 (after-tax) was recorded in other comprehensive loss, primarily due to the decrease in the discount rate, which was partially offset by the plan asset performance that was greater than expected, and by the amortization of actuarial losses. In 2018, a net loss of $114 (after-tax) was recorded in other comprehensive loss, primarily due to the impact of the adoption of new accounting guidance that permits a reclassification to Retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017, as well as the plan asset performance that was less than expected, which were partially offset by the increase in the discount rate and the amortization of actuarial losses.

Stock-Based Compensation. Howmet recognizes compensation expense for employee equity grants using the non-substantive vesting period approach, in which the expense is recognized ratably over the requisite service period based on the grant date fair value. Forfeitures are accounted for as they occur. The fair value of new stock options is estimated on the date of grant using a lattice-pricing model. The fair value of performance awards containing a market condition is valued using a Monte Carlo valuation model. Determining the fair value at the grant date requires judgment, including estimates for the average risk-free interest rate, dividend yield, volatility, and exercise behavior. These assumptions may differ significantly between grant dates because of changes in the actual results of these inputs that occur over time.

Compensation expense recorded in 2020, 2019, and 2018 was $46 ($42 after-tax), $69 ($63 after-tax), and $40 ($31 after-tax), respectively.

Income Taxes. The provision (benefit) for income taxes is determined using the asset and liability approach of accounting for income taxes. Under this approach, the provision (benefit) for income taxes represents income taxes paid or payable (or received or receivable) based on current year pre-tax income plus the change in deferred taxes during the year. Deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid, and result from differences between the financial and tax bases of Howmet’s assets and liabilities and are adjusted for changes in tax rates and tax laws when enacted.

Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. In evaluating the need for a valuation allowance, management considers all potential sources of taxable income, including income available in carry-back periods, future reversals of taxable temporary differences, projections of taxable income, and income from tax planning strategies, as well as all available positive and negative evidence. Positive evidence includes factors such as a history of profitable operations, projections of future profitability within the carryforward period, including from tax planning strategies, and Howmet’s experience with similar operations. Existing favorable contracts and the ability to sell products into established markets are additional positive evidence. Negative evidence includes items such as cumulative losses, projections of future losses, or carryforward periods that are not long enough to allow for the utilization of a deferred tax asset based on existing projections of income. Deferred tax assets for which no valuation allowance is recorded may not be realized upon changes in facts and circumstances, resulting in a future charge to establish a valuation allowance.

Table of Contents

Existing valuation allowances are re-examined under the same standards of positive and negative evidence. If it is determined that it is more likely than not that a deferred tax asset will be realized, the appropriate amount of the valuation allowance, if any, is released. Deferred tax assets and liabilities are also re-measured to reflect changes in underlying tax rates due to law changes and the granting and lapse of tax holidays.

The 2017 Act created a new requirement that certain income earned by foreign subsidiaries, Global Intangible Low Taxed Income ("GILTI"), must be included in the gross income of the U.S. shareholder. In 2018, Howmet made a final accounting policy election to apply a tax law ordering approach when considering the need for a valuation allowance on net operating losses expected to offset GILTI inclusions. Under this approach, reductions in cash tax savings are not considered as part of the valuation allowance assessment. Instead, future GILTI inclusions are considered a source of taxable income that support the realizability of deferred tax assets.

Tax benefits related to uncertain tax positions taken or expected to be taken on a tax return are recorded when such benefits meet a more likely than not threshold. Otherwise, these tax benefits are recorded when a tax position has been effectively settled, which means that the statute of limitations has expired or the appropriate taxing authority has completed their examination even though the statute of limitations remains open. Interest and penalties related to uncertain tax positions are recognized as part of the provision for income taxes and are accrued beginning in the period that such interest and penalties would be applicable under relevant tax law until such time that the related tax benefits are recognized.

Management’s Reports to Howmet Shareholders

Management’s Report on Financial Statements and Practices

The accompanying Consolidated Financial Statements of Howmet Aerospace Inc. and its subsidiaries (the “Company”) were prepared by management, which is responsible for their integrity and objectivity. The statements were prepared in accordance with accounting principles generally accepted in the United States of America and include amounts that are based on management’s best judgments and estimates. The other financial information included in the annual report is consistent with that in the financial statements.

Management also recognizes its responsibility for conducting the Company’s affairs according to the highest standards of personal and corporate conduct. This responsibility is characterized and reflected in key policy statements issued from time to time regarding, among other things, conduct of its business activities within the laws of the host countries in which the Company operates and potentially conflicting outside business interests of its employees. The Company maintains a systematic program to assess compliance with these policies.

Management’s Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting for the Company. In order to evaluate the effectiveness of internal control over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act, management has conducted an assessment, including testing, using the criteria in Internal Control—Integrated Framework (2013), issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO"). The Company’s system of internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. The Company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with accounting principles generally accepted in the United States of America, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Based on the assessment, management has concluded that the Company maintained effective internal control over financial reporting as of December 31, 2020, based on criteria in Internal Control—Integrated Framework (2013) issued by the COSO.

The effectiveness of the Company’s internal control over financial reporting as of December 31, 2020 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report, which is included herein.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of Howmet Aerospace Inc.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheet of Howmet Aerospace Inc. and its subsidiaries (the “Company”) as of December 31, 2020 and 2019, and the related consolidated statements of operations, of comprehensive income, of changes in equity and of cash flows for each of the three years in the period ended December 31, 2020, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

Change in Accounting Principle

As discussed in Note B to the consolidated financial statements, the Company changed the manner in which it accounts for leases in 2019.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Goodwill Impairment Assessments – Engineered Structures Reporting Unit

As described in Notes A and P to the consolidated financial statements, the Company’s consolidated goodwill balance was $4,102 million as of December 31, 2020, and the amount of the goodwill associated with the Engineered Structures reporting unit was $304 million. Goodwill is reviewed for impairment annually (in the fourth quarter) or more frequently if indicators of impairment exist. During the first quarter of 2020, management performed a quantitative impairment test for the Engineered Structures reporting unit and concluded that it was not impaired. The evaluation of impairment involves comparing the current fair value of each reporting unit to its carrying value, including goodwill. Fair value is estimated using a discounted cash flow model. The determination of fair value using this technique requires management to use significant estimates and assumptions related to forecasting operating cash flows, including sales growth, production costs, capital spending, and discount rate.

The principal considerations for our determination that performing procedures relating to the goodwill impairment assessments of the Engineered Structures reporting unit is a critical audit matter are the significant judgment by management when developing the fair value measurements of the reporting unit. This in turn led to a high degree of auditor judgment, effort and subjectivity in performing procedures and evaluating audit evidence related to management’s cash flow projections and significant assumptions related to sales growth, production costs, and discount rate for the first quarter assessment, and sales growth and production costs for the annual impairment assessment. In addition, the audit effort involved the use of professionals with specialized skill and knowledge.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to management’s goodwill impairment assessments, including controls over the valuation of the Company’s Engineered Structures reporting unit. These procedures also included, among others, testing management’s process for developing the fair value estimates; evaluating the appropriateness of the discounted cash flow models and performing sensitivity analyses over the assumptions; testing the completeness and accuracy of underlying data used in the models; and evaluating the reasonableness of the significant assumptions used by management related to sales growth, production costs, and discount rate for the first quarter assessment and sales growth and production costs for the annual impairment assessment. Evaluating management’s assumptions related to sales growth and production costs involved evaluating whether the assumptions used by management were reasonable by considering (i) the current and past performance of the reporting unit, (ii) the consistency with relevant industry data, and (iii) considering whether the assumptions were consistent with evidence obtained in other areas of the audit. Professionals with specialized skill and knowledge were used to assist in the evaluation of the discounted cash flow models and, for the first quarter assessment, the discount rate assumption.

Notes to the Consolidated Financial Statements

(dollars in millions, except per-share amounts)

A. Summary of Significant Accounting Policies

Basis of Presentation. The Consolidated Financial Statements of Howmet Aerospace Inc. (formerly known as Arconic Inc.) and subsidiaries (“Howmet” or the “Company”) are prepared in conformity with accounting principles generally accepted in the United States of America ("GAAP") and require management to make certain judgments, estimates, and assumptions. These estimates are based on historical experience and, in some cases, assumptions based on current and future market experience, including considerations relating to the impact of the global pandemic coronavirus (“COVID-19”). The impact of COVID-19 is rapidly changing and of unknown duration and macroeconomic impact and as a result, these considerations remain highly uncertain. We have made our best estimates using all relevant information available at the time, but it is possible that our estimates will differ from our actual results and affect the Consolidated Financial Statements in future periods and potentially require adverse adjustments to the recoverability of goodwill, intangible and long-lived assets, the realizability of deferred tax assets and other judgments and estimations and assumptions. These may affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements. They also may affect the reported amounts of sales and expenses during the reporting period. Actual results could differ from those estimates upon subsequent resolution of identified matters.

The separation of Arconic Inc. into two standalone, publicly-traded companies, Howmet Aerospace Inc. and Arconic Corporation, (the “Arconic Inc. Separation Transaction”) occurred on April 1, 2020. The Engineered Products and Forgings ("EP&F") segment remained in the existing company which was renamed Howmet Aerospace Inc. The Global Rolled Products ("GRP") segment was the Spin Co. and was named Arconic Corporation. In the second quarter of 2020, in conjunction with the Arconic Inc. Separation Transaction, the Company realigned its operations by separating the former EP&F segment into four new segments: Engine Products, Fastening Systems, Engineered Structures and Forged Wheels. See Note D for further details.

The financial results of Arconic Corporation for all periods prior to the Arconic Inc. Separation Transaction have been retrospectively reflected in the Statement of Consolidated Operations as discontinued operations and, as such, have been excluded from continuing operations and segment results for all periods presented. In addition, the related assets and liabilities associated with Arconic Corporation in the December 2019 Consolidated Balance Sheet are classified as assets and liabilities of discontinued operations. The cash flows, comprehensive income, and equity related to Arconic Corporation have not been segregated and are included in the Statement of Consolidated Cash Flows, Statement of Consolidated Comprehensive Income, and Statement of Changes in Consolidated Equity, respectively, for all periods prior to the Arconic Inc. Separation Transaction. See Note C for additional information related to the Arconic Inc. Separation Transaction and discontinued operations.

The Company derived approximately 69%, 71% and 70% of its revenue from products sold to the aerospace end-market for the years ended December 31, 2020, 2019 and 2018. As a result of COVID-19 and its impact on the aerospace industry to-date, the possibility exists that there could be a sustained impact to our operations and financial results. Since the start of the pandemic, certain original equipment manufacturer (“OEM”) customers have reduced production or suspended manufacturing operations in North America and Europe on a temporary basis. While the pandemic has resulted in the temporary closure of a small number of the Company's manufacturing facilities, all of our manufacturing facilities are currently operating. Since the duration of the pandemic is uncertain, the Company is taking a series of actions to address the financial impact, including announcing certain headcount reductions and reducing certain cash outflows by suspending dividends on common stock and reducing the level of its capital expenditures to preserve cash and maintain liquidity.

The Company identified a misclassification in the presentation of changes in accounts payable and capital expenditures in its previously issued Statement of Consolidated Cash Flows during 2020. Although management has determined that such misclassification did not materially misstate the Statement of Consolidated Cash Flows for the year ended December 31, 2019, the Company has revised it resulting in a $55 increase to previously reported capital expenditures and decrease to cash provided from investing activities with a corresponding reduction (decrease) in accounts payable, trade and increase in cash provided by operations.

A $16 deferred tax error was identified related to periods prior to 2018 during 2020. Although management has determined it was not material to any periods, the Company has revised its Statement of Changes in Consolidated Equity for the years ended December 31, 2019 and 2018 to present the correction as a reduction to Retained Earnings as of December 31, 2017. The accompanying Consolidated Balance Sheet at December 31, 2019 also reflects the revision for such tax item.

Principles of Consolidation. The Consolidated Financial Statements include the accounts of Howmet Aerospace Inc. and companies in which Howmet Aerospace Inc. has a controlling interest. Intercompany transactions have been eliminated. Investments in affiliates in which Howmet Aerospace Inc. cannot exercise significant influence that do not have readily

Table of Contents

determinable fair values are accounted for at cost less impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer.

Management also evaluates whether a Howmet Aerospace Inc. entity or interest is a variable interest entity and whether Howmet Aerospace Inc. is the primary beneficiary. Consolidation is required if both of these criteria are met. Howmet Aerospace Inc. does not have any variable interest entities requiring consolidation.

Cash Equivalents. Cash equivalents are highly liquid investments purchased with an original maturity of three months or less.

Inventory Valuation. Inventories are carried at the lower of cost and net realizable value with the cost of inventories determined under a combination of the first-in, first-out ("FIFO"), last-in, first-out ("LIFO") and average-cost methods. See Note N for further details.

Properties, Plants, and Equipment. Properties, plants, and equipment are recorded at cost. Depreciation is recorded principally on the straight-line method at rates based on the estimated useful lives of the assets.

The following table details the weighted-average useful lives of structures and machinery and equipment by reporting segment (numbers in years):


	Structures	Machinery and equipment
Engine Products	30	16
Fastening Systems	28	17
Engineered Structures	28	18
Forged Wheels	29	18

Gains or losses from the sale of asset groups are generally recorded in Restructuring and other charges while the sale of individual assets are recorded in Other expense (income), net (see policy below for assets classified as held for sale and discontinued operations). Repairs and maintenance are charged to expense as incurred. Interest related to the construction of qualifying assets is capitalized as part of the construction costs.

Properties, plants, and equipment are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets (asset group) may not be recoverable. Recoverability of assets is determined by comparing the estimated undiscounted net cash flows of the operations related to the assets (asset group) to their carrying amount. An impairment loss would be recognized when the carrying amount of the assets (asset group) exceeds the estimated undiscounted net cash flows. The amount of the impairment loss to be recorded is measured as the excess of the carrying value of the assets (asset group) over their fair value, with fair value determined using the best information available, which generally is a discounted cash flow ("DCF") model. The determination of what constitutes an asset group, the associated estimated undiscounted net cash flows, and the estimated useful lives of the assets also require significant judgments. See Note O for further details.

Goodwill is allocated among and evaluated for impairment at the reporting unit level, which is defined as an operating segment or one level below an operating segment. Howmet had four reporting units composed of the Engine Products, Fastening Systems, Engineered Structures and Forged Wheels segments.

Howmet determines annually, based on facts and circumstances, which of its reporting units will be subject to the qualitative assessment. For those reporting units where a qualitative assessment is either not performed or for which the conclusion is that

an impairment is more likely than not, a quantitative impairment test will be performed. Howmet's policy is that a quantitative impairment test be performed for each reporting unit at least once during every three-year period.

During the first quarter of 2020, Howmet's market capitalization declined significantly compared to the fourth quarter of 2019. Over the same period, the equity value of our peer group companies, and the overall U.S. stock market also declined significantly amid market volatility. In addition, as a result of the COVID-19 pandemic and measures designed to contain the spread, sales globally to customers in the aerospace and commercial transportation industries impacted by COVID-19 have been and are expected to continue to be negatively impacted as a result of disruption in demand. As a result of these macroeconomic factors, we performed a qualitative impairment test to evaluate whether it is more likely than not that the fair value of any of our reporting units is less than its carrying value. As a result of this assessment, the Company performed a quantitative impairment test in the first quarter for the Engineered Structures reporting unit and concluded that though the margin between the fair value of the reporting unit and carrying value had declined from approximately 60% to approximately 15%, it was not impaired. Consistent with prior practice, a discounted cash flow model was used to estimate the current fair value of the reporting unit. The significant assumptions and estimates utilized to determine fair value were developed utilizing current market and forecast information reflecting the disruption in demand that has and is expected to negatively impact the Company’s sales globally in the aerospace industry. During the second and third quarters of 2020, there were no indicators of impairment identified for the Engineered Structures reporting unit.

During the 2020 annual review of goodwill in the fourth quarter, management proceeded directly to the quantitative impairment test for all four of its reporting units. The estimated fair values for each of the four reporting units exceeded their respective carrying values by more than 50%, thus, there was no goodwill impairment. Under the quantitative impairment test, the evaluation of impairment involves comparing the current fair value of each reporting unit to its carrying value, including goodwill. Howmet uses a DCF model to estimate the current fair value of its reporting units when testing for impairment, as management believes forecasted cash flows are the best indicator of such fair value. A number of significant assumptions and estimates are involved in the application of the DCF model to forecast operating cash flows, including sales growth, production costs, capital spending, and discount rate. Most of these assumptions vary significantly among the reporting units. Cash flow forecasts are generally based on approved business unit operating plans for the early years and historical relationships in later years. The WACC rate for the individual reporting units is estimated with the assistance of valuation experts. The annual goodwill impairment tests in the fourth quarter of 2020, 2019 and 2018 indicated that goodwill was not impaired for any of the Company’s reporting units. If actual results or external market factors decline significantly from management’s estimates, future goodwill impairment charges (or the amount by which the carrying amount exceeds the reporting unit’s fair value without exceeding the total amount of goodwill allocated to that reporting unit) may be necessary and could be material.

In the first quarter of 2020, management transferred its Savannah, Georgia business from the Engine Products reporting unit to the Engineered Structures reporting unit. As a result of the reorganization, these reporting units were evaluated for impairment during the first quarter of 2020. The estimated fair value of each of these reporting units substantially exceeded their carrying value; thus, there was no goodwill impairment. In the second quarter of 2019, the Company transferred its castings operations from Engineered Structures to Engine Products. As a result, these reporting units were evaluated for impairment during the second quarter of 2019. The estimated fair value of each of these reporting units substantially exceeded their carrying value; thus, there was no impairment.

In the second quarter of 2019, as a result of the decline in the forecasted financial performance and related impairment of long-lived assets of the Disks asset group which composed business currently in the Engine Products and Engineered Structures segments (see Note O), the Company also performed an interim impairment evaluation of goodwill for Engine Products. The estimated fair value of the Engine Products reporting unit was substantially in excess of its carrying value; thus, there was no impairment of goodwill.

In connection with the interim impairment evaluation of long-lived assets for the Disks asset group in the second quarter of 2018, which resulted from a decline in forecasted financial performance for the business in connection with its updated three-year strategic plan, the Company also performed an interim impairment evaluation of goodwill for Engine Products. The estimated fair value of the reporting unit was substantially in excess of the carrying value; thus, there was no impairment of goodwill.

Leases. The Company determines whether a contract contains a lease at inception. The Company leases land and buildings, plant equipment, vehicles, and computer equipment which have been classified as operating leases. Certain real estate leases include one or more options to renew; the exercise of lease renewal options is at the Company’s discretion. The Company includes renewal option periods in the lease term when it is determined that the options are reasonably certain to be exercised. Certain of Howmet's real estate lease agreements include rental payments that either have fixed contractual increases over time or adjust periodically for inflation. Certain of the Company's lease agreements include variable lease payments. The variable portion of payments is not included in the initial measurement of the right-of-use asset or lease liability due to the uncertainty of the payment amount and is recorded as lease cost in the period incurred. The Company also rents or subleases certain real estate to third parties, which is not material to the consolidated financial statements.

Operating lease right-of-use assets and lease liabilities with an initial term greater than 12 months are recorded on the balance sheet at the present value of the future minimum lease payments over the lease term at the lease commencement date and are recognized as lease expense on a straight-line basis over the lease term. The Company uses an incremental collateralized borrowing rate based on the information available at the lease commencement date in determining the present value of future payments, as most of its leases do not provide an implicit rate. The operating lease right-of-use assets also include any lease prepayments made and were reduced by lease incentives and accrued exit costs.

Environmental Matters. Expenditures for current operations are expensed or capitalized, as appropriate. Expenditures relating to existing conditions caused by past operations, which will not contribute to future sales, are expensed. Liabilities are recorded when remediation costs are probable and can be reasonably estimated. The liability may include costs such as site investigations, consultant fees, feasibility studies, outside contractors, and monitoring expenses. Estimates are generally not discounted or reduced by potential claims for recovery. Claims for recovery are recognized when probable and as agreements are reached with third parties. The estimates also include costs related to other potentially responsible parties to the extent that Howmet has reason to believe such parties will not fully pay their proportionate share. The liability is continuously reviewed and adjusted to reflect current remediation progress, prospective estimates of required activity, and other factors that may be relevant, including changes in technology or regulations.

Litigation Matters. For asserted claims and assessments, liabilities are recorded when an unfavorable outcome of a matter is deemed to be probable and the loss is reasonably estimable. Management determines the likelihood of an unfavorable outcome based on many factors such as the nature of the matter, available defenses and case strategy, progress of the matter, views and opinions of legal counsel and other advisors, applicability and success of appeals processes, and the outcome of similar historical matters, among others. Once an unfavorable outcome is deemed probable, management weighs the probability of estimated losses, and the most reasonable loss estimate is recorded. If an unfavorable outcome of a matter is deemed to be reasonably possible, then the matter is disclosed and no liability is recorded. With respect to unasserted claims or assessments, management must first determine that the probability that an assertion will be made is likely, then, a determination as to the likelihood of an unfavorable outcome and the ability to reasonably estimate the potential loss is made. Legal matters are reviewed on a continuous basis to determine if there has been a change in management’s judgment regarding the likelihood of an unfavorable outcome or the estimate of a potential loss.

Revenue Recognition. The Company's contracts with customers are comprised of acknowledged purchase orders incorporating the Company’s standard terms and conditions, or for larger customers, may also generally include terms under negotiated multi-year agreements. These contracts with customers typically consist of the manufacture of products which represent single performance obligations that are satisfied upon transfer of control of the product to the customer. The Company produces fastening systems; seamless rolled rings; investment castings, including airfoils; extruded, machined and formed aircraft parts; and forged aluminum commercial vehicle wheels. Transfer of control is assessed based on alternative use of the products we produce and our enforceable right to payment for performance to date under the contract terms. Transfer of control and revenue recognition generally occur upon shipment or delivery of the product, which is when title, ownership and risk of loss pass to the customer and is based on the applicable shipping terms. The shipping terms vary across all businesses and depend on the

Table of Contents

product, the country of origin, and the type of transportation (truck, train, or vessel). An invoice for payment is issued at time of shipment. Our segments set commercial terms on which Howmet sells products to its customers. These terms are influenced by industry custom, market conditions, product line (specialty versus commodity products), and other considerations.

In certain circumstances, Howmet receives advanced payments from its customers for product to be delivered in future periods. These advanced payments are recorded as deferred revenue until the product is delivered and title and risk of loss have passed to the customer in accordance with the terms of the contract. Deferred revenue is included in Other current liabilities and Other noncurrent liabilities and deferred credits on the accompanying Consolidated Balance Sheet. Advanced payments were $97 and $85 at December 31, 2020 and December 31, 2019, respectively.

Income Taxes. The provision for income taxes is determined using the asset and liability approach of accounting for income taxes. Under this approach, the provision for income taxes represents income taxes paid or payable (or received or receivable) for the current year plus the change in deferred taxes during the year. Deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid, and result from differences between the financial and tax bases of Howmet’s assets and liabilities and are adjusted for changes in tax rates and tax laws when enacted.

Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. In evaluating the need for a valuation allowance, management considers all potential sources of taxable income, including income available in carryback periods, future reversals of taxable temporary differences, projections of taxable income, and income from tax planning strategies, as well as all available positive and negative evidence. Positive evidence includes factors such as a history of profitable operations, projections of future profitability within the carryforward period, including from tax planning strategies, and Howmet’s experience with similar operations. Existing favorable contracts and the ability to sell products into established markets are additional positive evidence. Negative evidence includes items such as cumulative losses, projections of future losses, or carryforward periods that are not long enough to allow for the utilization of a deferred tax asset based on existing projections of income. Deferred tax assets for which no valuation allowance is recorded may not be realized upon changes in facts and circumstances, resulting in a future charge to establish a valuation allowance. Existing valuation allowances are re-examined under the same standards of positive and negative evidence. If it is determined that it is more likely than not that a deferred tax asset will be realized, the appropriate amount of the valuation allowance, if any, is released. Deferred tax assets and liabilities are also remeasured to reflect changes in underlying tax rates due to law changes and the granting and lapse of tax holidays.

In 2018, the Company made a final accounting policy election to apply a tax law ordering approach when considering the need for a valuation allowance on net operating losses expected to offset Global Intangible Low-Taxed Income ("GILTI") inclusions. Under this approach, reductions in cash tax savings are not considered as part of the valuation allowance assessment. Instead, future GILTI inclusions are considered a source of taxable income that support the realizability of deferred tax assets.

Foreign Currency. The local currency is the functional currency for Howmet’s significant operations outside the United States ("U.S."), except for certain operations in Canada, United Kingdom and France, where the U.S. dollar is used as the functional currency. The determination of the functional currency for Howmet’s operations is made based on the appropriate economic and management indicators.

Acquisitions. Howmet’s business acquisitions are accounted for using the acquisition method. The purchase price is allocated to the assets acquired and liabilities assumed based on their estimated fair values. Any excess purchase price over the fair value of the net assets acquired is recorded as goodwill. For all acquisitions, operating results are included in the Statement of Consolidated Operations from the date of the acquisition.

Table of Contents

Discontinued Operations and Assets Held for Sale. For those businesses where management has committed to a plan to divest, each business is valued at the lower of its carrying amount or estimated fair value less cost to sell. If the carrying amount of the business exceeds its estimated fair value, an impairment loss is recognized. Fair value is estimated using accepted valuation techniques such as a DCF model, valuations performed by third parties, earnings multiples, or indicative bids, when available. A number of significant estimates and assumptions are involved in the application of these techniques, including the forecasting of markets and market share, sales volumes and prices, costs and expenses, and multiple other factors. Management considers historical experience and all available information at the time the estimates are made; however, the fair value that is ultimately realized upon the divestiture of a business may differ from the estimated fair value reflected in the Consolidated Financial Statements. Depreciation and amortization expense is not recorded on assets of a business to be divested once they are classified as held for sale. Businesses to be divested are generally classified in the Consolidated Financial Statements as either discontinued operations or held for sale.

For businesses classified as discontinued operations, the balance sheet amounts and results of operations should be reclassified from their historical presentation to assets and liabilities of discontinued operations on the Consolidated Balance Sheet and to discontinued operations on the Statement of Consolidated Operations, respectively, for all periods presented. The gains or losses associated with these divested businesses are recorded in discontinued operations on the Statement of Consolidated Operations. The Statement of Consolidated Cash Flows is not required to be reclassified for discontinued operations for any period. Segment information does not include the assets or operating results of businesses classified as discontinued operations for all periods presented. These businesses are expected to be disposed of within one year.

For businesses classified as held for sale that do not qualify for discontinued operations treatment, the balance sheet and cash flow amounts should be reclassified from their historical presentation to assets and liabilities of operations held for sale for all periods presented. The results of operations continue to be reported in continuing operations. The gains or losses associated with these divested businesses are recorded in Restructuring and other charges on the Statement of Consolidated Operations. The segment information includes the assets and operating results of businesses classified as held for sale for all periods presented.

B. Recently Adopted and Recently Issued Accounting Guidance

Recently Adopted Accounting Guidance.

On January 1, 2020, the Company adopted changes issued by the Financial Accounting Standards Board ("FASB") related to the impairment model for expected credit losses. The new impairment model (known as the current expected credit loss ("CECL") model) is based on expected losses rather than incurred losses. The Company recognizes as an allowance its estimate of expected credit losses. The CECL model applies to most debt instruments, trade receivables, lease receivables, financial guarantee contracts, and other loan commitments and requires the measurement of expected credit losses on assets including those that have a low risk of loss. The adoption of this new guidance did not have a material impact on the Consolidated Financial Statements.

In August 2018, the FASB issued guidance that impacts disclosures for defined benefit pension plans and other postretirement benefit plans. These changes became effective for Howmet's annual report for the year ended December 31, 2020 which did not have a material impact on its Consolidated Financial Statements.

In February 2016, the FASB issued changes to the accounting and presentation of leases. These changes required lessees to recognize a right-of-use asset and lease liability on the balance sheet, initially measured at the present value of lease payments for all operating leases with a term greater than 12 months. These changes became effective for the Company on January 1, 2019 and have been applied using the modified retrospective approach as of the date of adoption, under which leases existing at, or entered into after, January 1, 2019 were required to be recognized and measured. Prior period amounts have not been adjusted and continue to be reflected in accordance with the Company’s historical accounting. The Company elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed the Company to carry forward the historical lease classification. The Company also elected to separate lease components from non-lease components for all classes of assets.

The adoption of this new lease standard resulted in the Company recording operating lease right-of-use assets and lease liabilities of approximately $320 on the Consolidated Balance Sheet as of January 1, 2019. The adoption of the new lease standard had no impact on the Statement of Consolidated Operations or Statement of Consolidated Cash Flows. The Company entered into a sale leaseback arrangement in October 2018 for a cast house that is now part of Arconic Corporation, and due to continuing involvement, the gain on sale was deferred. In connection with the adoption of the new lease accounting standard on January 1, 2019, the arrangement no longer required that the gain be deferred. As such, the associated $73 deferred gain, net of tax was recognized as a cumulative effect of an accounting change within Accumulated deficit in its Consolidated Balance Sheet and Statement of Changes in Consolidated Equity.

In August 2017, the FASB issued guidance that made more financial and nonfinancial hedging strategies eligible for hedge accounting. It also amended the presentation and disclosure requirements and changed how companies assess effectiveness. It is

Table of Contents

intended to more closely align hedge accounting with companies’ risk management strategies, simplify the application of hedge accounting, and increase transparency as to the scope and results of hedging programs. These changes became effective for the Company on January 1, 2019. For cash flow hedges, Howmet recorded a cumulative effect adjustment of $2 related to eliminating the separate measurement of ineffectiveness by decreasing Accumulated other comprehensive loss and increasing Retained earnings on its Consolidated Balance Sheet and Statement of Changes in Consolidated Equity. The amendments to presentation and disclosure are required prospectively. Howmet has determined that under the new accounting guidance it is able to more broadly use cash flow hedge accounting for its variable priced inventory purchases and customer sales.

In February 2018, the FASB issued guidance that allows an optional reclassification from Accumulated other comprehensive loss to Accumulated deficit for stranded tax effects resulting from the Tax Cuts and Jobs Act enacted on December 22, 2017. Stranded tax effects were created when deferred taxes, originally established in Other comprehensive income at 35%, were revalued to 21% as a component of income tax expense from continuing operations. The Company elected to early adopt this provision in the fourth quarter of 2018 and reclassified $367 of beneficial stranded tax effects in Accumulated other comprehensive loss to Retained earnings in its Consolidated Balance Sheet and Statement of Changes in Consolidated Equity.

Recently Issued Accounting Guidance.

In December 2019, the FASB issued guidance that is intended to simplify various aspects related to the accounting for income taxes. These changes became effective for Howmet on January 1, 2021. The adoption of this new guidance will not have a material impact on its Consolidated Financial Statements.

In March 2020, the FASB issued amendments that provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform, if certain criteria are met. The amendments apply only to contracts and hedging relationships that reference London Inter-bank Offered Rate ("LIBOR") or another reference rate expected to be discontinued due to reference rate reform. These amendments are effective immediately and may be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2022. Management is currently evaluating the potential impact of these changes on the Consolidated Financial Statements.

C. Arconic Inc. Separation Transaction and Discontinued Operations

On April 1, 2020, the Company completed the previously announced separation of its business into two independent, publicly-traded companies. Following the Arconic Inc. Separation Transaction, Arconic Corporation held the Global Rolled Products businesses (global rolled products, aluminum extrusions, and building and construction systems) previously held by the Company. The Company retained the Engineered Products and Forgings businesses (engine products, fastening systems, engineered structures, and forged wheels).

The Company's Board of Directors approved the completion of the separation on February 5, 2020, which was effected by the distribution (the "Distribution") by the Company of all of the outstanding common stock of Arconic Corporation on April 1, 2020 to the Company’s stockholders who held shares as of the close of business on March 19, 2020 (the "Record Date"). In the Distribution, each Company stockholder of record as of the Record Date received one share of Arconic Corporation common stock for every four shares of the Company’s common stock held as of the Record Date. The Company did not issue fractional shares of Arconic Corporation common stock in the Distribution. Instead, each stockholder otherwise entitled to a fractional share of Arconic Corporation common stock received cash in lieu of fractional shares.

In connection with the Arconic Inc. Separation Transaction, the Company entered into several agreements with Arconic Corporation that govern the relationship between the Company and Arconic Corporation following the Distribution, including the following: a Separation and Distribution Agreement, Tax Matters Agreement, Employee Matters Agreement, certain Patent, Know-How, Trade Secret License and Trademark License Agreements, and Raw Material Supply Agreements.

On February 7, 2020, Arconic Corporation completed an offering of $600 aggregate principal amount of 6.125% senior secured second-lien notes due 2028. On March 25, 2020, Arconic Corporation entered into a credit agreement which provided for a $600 aggregate principal amount seven-year senior secured first-lien loan B facility and a revolving credit facility which is guaranteed by certain of Arconic Corporation's wholly-owned domestic subsidiaries and secured on a first-priority basis by liens on substantially all assets of Arconic Corporation and subsidiary guarantors. Arconic Corporation used the proceeds to make payment to the Company to fund the transfer of certain assets to Arconic Corporation relating to the Arconic Inc. Separation Transaction and for general corporate purposes. The Company incurred debt issuance costs of $45 associated with these issuances for the first quarter of 2020 and year ended December 31, 2020.

On February 1, 2020, the Company completed the sale of its rolling mill in Itapissuma, Brazil for $50 in cash which resulted in a loss of $59, of which $53 was recognized in discontinued operations in the second half of 2019 and $6 in the first quarter of 2020 and year ended December 31, 2020. On March 1, 2020, the Company sold its hard alloy extrusions plant in South Korea

Table of Contents

for $62 in cash, which resulted in a gain that was recognized in discontinued operations in the first quarter of 2020 and year ended December 31, 2020.

On October 31, 2018, the Company sold its Texarkana, Texas rolling mill and cast house, which had a combined net book value of $63, to Ta Chen International, Inc. for $302 in cash, including the settlement of post-closing adjustments, plus additional contingent consideration of up to $50. The contingent consideration related to the achievement of various milestones within 36 months of the transaction closing date associated with operationalizing the rolling mill equipment. As part of the agreement, the Company produced aluminum slab at the facility for a period of 18 months through a lease back of the cast house building and equipment. The sale of the rolling mill and cast house had been accounted for separately. The gain on the sale of the rolling mill of $154, including the fair value of contingent consideration of $5, was recorded in 2018. In 2019, the Company received additional contingent consideration of $20 and recorded a gain. These amounts were recorded in discontinued operations in the Statement of Consolidated Operations. The Company had continuing involvement related to the lease back of the cast house. As a result, in 2018, the Company continued to treat the cast house building and equipment that it sold to Ta Chen as owned. In conjunction with the adoption of the new lease accounting standard on January 1, 2019 (see Note B), the Company's continuing involvement no longer required deferral of the recognition of the cast house sale. As such, the cash proceeds, properties, plant and equipment and deferred tax assets related to the cast house were reclassified to Retained earnings as a cumulative effect of an accounting change of $73 in 2018.

D. Segment and Geographic Area Information

Howmet is a global leader in lightweight metals engineering and manufacturing. Howmet’s innovative, multi-material products, which include nickel, titanium, aluminum, and cobalt, are used worldwide in the aerospace (commercial and defense), commercial transportation, and industrial and other end markets. Segment performance under Howmet’s management reporting system is evaluated based on a number of factors; however, the primary measure of performance is Segment operating profit. Howmet’s definition of Segment operating profit is Operating income excluding Special items. Special items include Restructuring and Other charges and Impairment of Goodwill. Segment operating profit may not be comparable to similarly titled measures of other companies. Differences between segment totals and consolidated Howmet are in Corporate.

Following the Arconic Inc. Separation Transaction, Howmet’s operations consist of four worldwide reportable segments as follows:

Engine Products

Fastening Systems

Table of Contents

Engineered Structures

Forged Wheels

Forged Wheels provides forged aluminum wheels and related products for heavy-duty trucks and the commercial transportation markets.

Goodwill

The Company had $4,102 of Goodwill at December 31, 2020, and the Company reviews it for impairment annually in the fourth quarter, or more frequently, if indicators exist or if a decision is made to sell or realign a business.

On January 1, 2020, management transferred the Savannah business from the Engine Products segment to the Engineered Structures segment, based on synergies with forgings technologies and manufacturing capabilities. As a result of the reorganization, goodwill of $17 was reallocated from Engine Products to Engineered Structures, and these reporting units were evaluated for impairment during the first quarter of 2020. The estimated fair value of each of these reporting units substantially exceeded their carrying value; thus, there was no goodwill impairment at the date the business was transferred.

During the first quarter of 2020, Howmet's market capitalization declined significantly compared to the fourth quarter of 2019. Over the same period, the equity value of our peer group companies, and the overall U.S. stock market also declined significantly amid market volatility. In addition, as a result of the COVID-19 pandemic and measures designed to contain the spread, global sales to customers in the aerospace and commercial transportation industries impacted by COVID-19 have been and are expected to be negatively impacted as a result of disruption in demand. As a result of these macroeconomic factors, we performed a qualitative impairment test to evaluate whether it is more likely than not that the fair value of any of our reporting units is less than its carrying value. As a result of this assessment, the Company performed a quantitative impairment test in the first quarter for the Engineered Structures reporting unit and concluded that though the margin between the fair value of the reporting unit and carrying value had declined from approximately 60% to approximately 15%, it was not impaired. Consistent with prior practice, a discounted cash flow model was used to estimate the current fair value of the reporting unit. The significant assumptions and estimates utilized to determine fair value were developed utilizing current market and forecast information reflecting the disruption in demand that has and is expected to negatively impact the Company’s sales globally in the aerospace industry. If our actual results or external market factors decline significantly from management’s estimates, future goodwill impairment charges may be necessary and could be material. During the second and third quarters of 2020, there were no indicators of impairment identified for the Engineered Structures reporting unit.

The accounting policies of the segments are the same as those described in the Summary of Significant Accounting Policies (see Note A). Transactions among segments are established based on negotiation among the parties. Differences between segment totals and Howmet’s consolidated totals for line items not reconciled are in Corporate.

H. Pension and Other Postretirement Benefits

Howmet maintains pension plans covering most U.S. employees and certain employees in foreign locations. Pension benefits generally depend on length of service and job grade. Substantially all benefits are paid through pension trusts that are sufficiently funded to ensure that all plans can pay benefits to retirees as they become due. Most salaried and non-bargaining hourly U.S. employees hired after March 1, 2006, participate in a defined contribution plan instead of a defined benefit plan.

Howmet also maintains health care and life insurance postretirement benefit plans covering eligible U.S. retired employees and certain retirees from foreign locations. Generally, the medical plans are unfunded and pay a percentage of medical expenses, reduced by deductibles and other coverage. Life benefits are generally provided by insurance contracts. Howmet retains the right, subject to existing agreements, to change or eliminate these benefits. All salaried and certain non-bargaining hourly U.S. employees hired after January 1, 2002 and certain bargaining hourly U.S. employees hired after July 1, 2010, are not eligible for postretirement health care benefits. All salaried and certain hourly U.S. employees that retire on or after April 1, 2008 are not eligible for postretirement life insurance benefits. Effective May 1, 2019, salaried employees and retirees are not eligible for postretirement life insurance benefits.

Effective January 1, 2015, Howmet no longer offers postretirement health care benefits to Medicare-eligible, primarily non-bargaining, U.S. retirees through Company-sponsored plans. Qualifying retirees (hired prior to January 1, 2002), both current and future, may access these benefits in the marketplace by purchasing coverage directly from insurance carriers.

On April 1, 2018, benefit accruals for future service and compensation under all of the Company's qualified and non-qualified defined benefit pension plans for U.S. salaried and non-bargaining hourly employees ceased. As a result of this change, in 2018, the Company recorded a decrease to the Accrued pension benefit liability of $136 related to the reduction of future benefits ($141 offset in Accumulated other comprehensive loss) and curtailment charges of $5 in Restructuring and other charges.

On April 13, 2018, the United Auto Workers ratified a new five-year labor agreement, covering approximately 1,300 U.S. employees, which expires on March 31, 2023. A provision within the agreement includes a retirement benefit increase for future retirees that participate in a defined benefit pension plan, which impacts approximately 300 of those employees. In addition, effective January 1, 2019, benefit accruals for future service of this group ceased. As result of these changes, in 2018, a curtailment charge of $9 was recorded in Restructuring and other charges.

In 2018, the Company announced that effective December 31, 2018, it would end all pre-Medicare medical, prescription drug and vision coverage for current and future salaried and non-bargained hourly employees and retirees of the Company and its subsidiaries. As a result of this change, in 2018, the Company recorded a decrease to the Accrued other postretirement benefits

Table of Contents

liability of $32 related to the reduction of future benefits, $4 offset in Accumulated other comprehensive loss, and a curtailment benefit of $28 in Restructuring and other charges.

In 2018, the company communicated to plan participants that effective in the first quarter of 2019, benefit accruals for future service and compensation for employees in the United Kingdom defined benefit pension plans will cease. The plan curtailment resulted in a $13 decrease in the Accrued pension benefits liability which was offset in Accumulated other comprehensive loss. Additionally, on October 29, 2018, the United Kingdom High Court ruled that defined benefit pension plans offering Guaranteed Minimum Pensions must review benefits accrued between May 1990 to April 1997 to ensure gender pay equality. The review resulted in an increase to the Accrued pension benefits liability of $9 and a corresponding curtailment charge that was recorded in Restructuring and other charges.

In 2019, the Company communicated to plan participants that for its U.S. salaried and non-bargained hourly retirees of the Company and its subsidiaries, it would eliminate the life insurance benefit effective May 1, 2019, and certain health care subsidies effective December 31, 2019. As a result of these changes, in 2019, the Company recorded a decrease to the Accrued other postretirement benefits liability of $75, which was offset by a curtailment benefit of $58 (of which $16 was recorded in Restructuring and other charges and $42 related to Arconic Corporation in Discontinued Operations) and $17 in Accumulated other comprehensive loss.

In June 2019, the Company and the United Steelworkers ("USW") reached a tentative three-year labor agreement that was ratified on July 11, 2019 covering approximately 3,400 employees at four U.S. locations of Arconic Corporation; the previous labor agreement expired on May 15, 2019. In 2019, the Company recognized $9 in Discontinued operations on the accompanying Statement of Consolidated Operations primarily for a one-time signing bonus for employees. Additionally, on July 25, 2019, the USW ratified a new four-year labor agreement covering approximately 560 employees at the Company’s Niles, Ohio facility. The prior labor agreement expired on June 30, 2018.

In 2020 and 2019, the Company applied settlement accounting to U.S. pension plans due to lump sum payments to participants which resulted in settlement charges of $8 and $9, respectively, that were recorded in Restructuring and other charges.

In 2020 the Company undertook a number of actions to reduce pension obligations in the U.K. by offering lump sum payments to certain plan participants and entering into group annuity contracts with a third-party carrier to pay and administer future annuity payments which resulted in settlement charges of $66 that were recorded in Restructuring and other charges in the Statement of Consolidated Operations. These actions reduced the number of pension plan participants in the U.K. by approximately half.

In 2020, the Company communicated to plan participants that for its U.S. salaried and non-bargained hourly retirees of the Company and its subsidiaries, it would eliminate certain health care subsidies effective December 31, 2021, and that for certain bargained retirees of the Company, it would eliminate certain health care subsidies effective December 31, 2021 and the life insurance benefit effective August 1, 2020. As a result of these amendments, the Company recorded a decrease to the Accrued other postretirement benefits liability of $6 in 2020, which was offset in Accumulated other comprehensive loss.

The U.S. discount rate is determined using a Company-specific yield curve model (above-median) developed with the assistance of an external actuary while both the U.K. and Canada utilize models developed internally by their respective actuary. The cash flows of the plans’ projected benefit obligations are discounted using a single equivalent rate derived from yields on high quality corporate bonds, which represent a broad diversification of issuers in various sectors, including finance and banking, industrials, transportation, and utilities, among others. The yield curve model parallels the plans’ projected cash flows, which have a global average duration of 12 years. The underlying cash flows of the bonds included in the model exceed the cash flows needed to satisfy the Company’s plans’ obligations multiple times.

Benefit accruals for future compensation under the Company’s major salaried and non-bargained hourly defined benefit pension plans have ceased. The rate of compensation increase no longer impacts the determination of the benefit obligation.

Weighted average assumptions used to determine net periodic benefit cost for pension and other postretirement benefit plans were as follows:


	2020		2019		2018
Discount rate to calculate service cost(1)	3.30	%	4.30	%	3.60	%
Discount rate to calculate interest cost(1)	2.70	%	3.90	%	3.30	%
Expected long-term rate of return on plan assets	6.00	%	5.60	%	5.90	%
Rate of compensation increase(2)	—	%	3.50	%	3.50	%
Cash balance plan interest crediting rate	3.00	%	3.00	%	3.00	%

(1)In all periods presented, the respective global discount rates were used to determine net periodic benefit cost for most pension plans for the full annual period. However, the discount rates for a limited number of plans were updated during 2020, 2019, and 2018 to reflect the remeasurement of these plans due to new union labor agreements, settlements, and/or curtailments. The updated discount rates used were not significantly different from the discount rates presented.

(2)Benefit accruals for future compensation under the Company’s major salaried and non-bargained hourly defined benefit pension plans have ceased. The rate of compensation increase no longer impacts the determination of the benefit obligation.

The expected long-term rate of return on plan assets (“EROA”) is generally applied to a five-year market-related value of plan assets (a fair value at the plan measurement date is used for certain non-U.S. plans). The process used by management to develop this assumption is one that relies on a combination of historical asset return information and forward-looking returns by asset class. As it relates to historical asset return information, management focuses on various historical moving averages when developing this assumption. While consideration is given to recent performance and historical returns, the assumption represents a long-term, prospective return. Management also incorporates expected future returns on current and planned asset allocations using information from various external investment managers and consultants, as well as management’s own judgment.

For 2020, 2019, and 2018, the U.S. expected long-term rate of return used by management was based on the prevailing and planned strategic asset allocations, as well as estimates of future returns by asset class. These rates fell within the respective range of the 20-year moving average of actual performance and the expected future return developed by asset class. In 2018, management reduced the expected long-term rate of return by 75 basis points to 7.00% for the U.S. Pension plans due to a decrease in the expected return by asset class and the 20-year moving average. For 2021, management anticipates that 7.00% will continue to be the expected long-term rate of return for the U.S. Pension plans. EROA assumptions are developed by country. Annual changes in the weighted average EROA are impacted by the relative size of the assets by country.

Assumed health care cost trend rates for U.S. other postretirement benefit plans were as follows:


	2020		2019		2018
Health care cost trend rate assumed for next year	5.50	%	5.50	%	5.50	%
Rate to which the cost trend rate gradually declines	4.50		4.50		4.50
Year that the rate reaches the rate at which it is assumed to remain	2023		2023		2022

The assumed health care cost trend rate is used to measure the expected cost of gross eligible charges covered by Howmet’s other postretirement benefit plans. For 2021, a 5.5% trend rate will be used, reflecting management’s best estimate of the change in future health care costs covered by the plans. The plans’ actual annual health care cost trend experience over the past three years has ranged from (3.8)% to 4.0%. Management does not believe this three-year range is indicative of expected increases for future health care costs over the long-term.

Plan Assets

Howmet’s pension plans’ investment policy at December 31, 2020 by asset class, were as follows:

Asset class

Policy range(1)

Equities

20–55%

Fixed income

25–55%

Other investments

15–35%

Total

(1)Policy range is for U.S. plan assets only, as both the U.K. and Canadian asset investment allocations are controlled by a third-party trustee with input from Howmet.

The principal objectives underlying the investment of the pension plans’ assets are to ensure that Howmet can properly fund benefit obligations as they become due under a broad range of potential economic and financial scenarios, maximize the long-term investment return with an acceptable level of risk based on such obligations, and broadly diversify investments across and within various asset classes to protect asset values against adverse movements. Specific objectives for long-term investment strategy include reducing the volatility of pension assets relative to pension liabilities and achieving diversification across the balance of the asset portfolio. The use of derivative instruments is permitted where appropriate and necessary for achieving overall investment policy objectives. The investment strategy uses long duration cash bonds and derivative instruments to offset a portion of the interest rate sensitivity of U.S. pension liabilities. Exposure to broad equity risk is decreased and diversified through investments in discretionary and systematic macro hedge funds, long/short equity hedge funds, high yield bonds, emerging market debt and global and emerging market equities. Investments are further diversified by strategy, asset class, geography, and sector to enhance returns and mitigate downside risk. A large number of external investment managers are used to gain broad exposure to the financial markets and to mitigate manager-concentration risk.

Investment practices comply with the requirements of the Employee Retirement Income Security Act of 1974 ("ERISA") and other applicable laws and regulations.

The following section describes the valuation methodologies used to measure the fair value of pension plan assets, including an indication of the level in the fair value hierarchy in which each type of asset is generally classified (see Note S for the definition of fair value and a description of the fair value hierarchy).

Equities. These securities consist of: (i) direct investments in the stock of publicly traded U.S. and non-U.S. companies, and equity derivatives, that are valued based on the closing price reported in an active market on which the individual securities are traded (generally classified in Level 1); (ii) the plans’ share of commingled funds that are invested in the stock of publicly traded companies and are valued at the net asset value of shares held at December 31 (included in Level 1 and Level 2); and (iii) direct investments in long/short equity hedge funds and private equity (limited partnerships and venture capital partnerships) that are valued at net asset value.

Fixed income. These securities consist of: (i) U.S. government debt that are generally valued using quoted prices (included in Level 1); (ii) cash and cash equivalents invested in publicly-traded funds and are valued based on the closing price reported in an active market on which the individual securities are traded (generally classified in Level 1); (iii) publicly traded U.S. and non-U.S. fixed interest obligations (principally corporate bonds and debentures) and are valued through consultation and evaluation with brokers in the institutional market using quoted prices and other observable market data (included in Level 2); (iv) fixed income derivatives that are generally valued using industry standard models with market-based observable inputs (included in Level 2); and (v) cash and cash equivalents invested in institutional funds and are valued at net asset value.

Table of Contents

Other investments. These investments include, among others: (i) exchange traded funds, such as gold, and real estate investment trusts and are valued based on the closing price reported in an active market on which the investments are traded (included in Level 1) and (ii) direct investments of discretionary and systematic macro hedge funds and private real estate (includes limited partnerships) and are valued at net asset value.

The fair value methods described above may not be indicative of net realizable value or reflective of future fair values. Additionally, while Howmet believes the valuation methods used by the plans’ trustees are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

The following table presents the fair value of pension plan assets classified under the appropriate level of the fair value hierarchy or net asset value:

Funding and Cash Flows

It is Howmet’s policy to fund amounts for pension plans sufficient to meet the minimum requirements set forth in applicable country benefits laws and tax laws. Periodically, Howmet contributes additional amounts as deemed appropriate. In 2020 and 2019, cash contributions to Howmet’s pension plans were $227 and $268, respectively, which includes $25 and $53, respectively, contributed to the Company’s U.S. plans that was in excess of the minimum required under ERISA.

The contributions to the Company’s pension plans in 2021 are estimated to be $140 (of which $130 is for U.S. plans), all of which are minimum required contributions.

During the third quarter of 2016, the Pension Benefit Guaranty Corporation approved management’s plan to separate the Alcoa Inc. pension plans between the Company and Alcoa Corporation. The plan stipulated that the Company make cash contributions of $150 over a period of 30 months (from November 1, 2016) to its two largest pension plans. The Company satisfied the requirements of the plan by making payments of $34, $66, and $50 in April 2019, March 2018, and April 2017, respectively.

Benefit payments expected to be paid to pension and other postretirement benefit plans’ participants and expected Medicare Part D subsidy receipts are as follows utilizing the current assumptions outlined above:


For the year ended December 31,	Pension benefits paid		Gross Other post- retirement benefits		Less Medicare Part D subsidy receipts		Net Other post- retirement benefits

Defined Contribution Plans

Howmet sponsors savings and investment plans in various countries, primarily in the U.S. Howmet’s contributions and expenses related to these plans were $73, $87, and $85 in 2020, 2019, and 2018, respectively. U.S. employees may contribute a portion of their compensation to the plans, and Howmet matches a portion of these contributions in equivalent form of the investments elected by the employee.

(1)In 2018, a $74 benefit was recorded related to the reversal of a foreign recapture obligation.

(2)In 2020, final regulations were issued that provided an election to exclude from GILTI any foreign earnings subject to a local country tax rate of at least 90% of the U.S. tax rate. The Company recorded a $30 benefit related to this tax law change. In 2018, the Company finalized its accounting for the Tax Cuts and Jobs Act of 2017 ("the 2017 Act”) and recorded an additional $59 charge.

(3)In 2020, a $104 valuation allowance was recorded related to deferred tax assets that were previously subject to a reserve that was otherwise released in 2020 as a result of a favorable Spanish tax case decision. In 2019, the Company released a $112 valuation allowance related to 2015 and 2016 foreign tax credits, subsequent to filing U.S. amended tax returns to deduct, rather than credit, foreign taxes.

(4)In 2020, the Company released a $64 reserve liability and a $104 reserve recorded as a contra balance against deferred tax assets as a result of a favorable Spanish tax case decision. A $30 benefit related to a previously uncertain U.S. tax position was also recognized in 2020. In 2018, the tax charge to establish the reserves related to the Spanish tax matter was partially offset by a $38 benefit related to a foreign reserve that was effectively settled.

(5)In 2019, the Company filed U.S. amended tax returns to deduct, rather than credit, 2015 and 2016 foreign taxes resulting in a $112 tax cost associated with the write-off of the deferred tax asset for the credit, partially offset by a $24 tax benefit for the deduction.

Table of Contents

On December 22, 2017, the 2017 Act was signed into law, making significant changes to the Internal Revenue Code. Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning after December 31, 2017, the transition of U.S. international taxation from a worldwide tax system to a territorial system, and a one-time transition tax on the non-previously taxed post-1986 foreign earnings and profits of certain U.S.-owned foreign corporations as of December 31, 2017. Also on December 22, 2017, Staff Accounting Bulletin No. 118 ("SAB 118"), Income Tax Accounting Implications of the Tax Cuts and Jobs Act, was issued by the SEC to address the application of U.S. GAAP for financial reporting. SAB 118 permitted the use of provisional amounts based on reasonable estimates in the financial statements. SAB 118 also provided that the tax impact may be considered incomplete in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the 2017 Act.

The Company calculated a reasonable estimate of the impact of the 2017 Act’s tax rate reduction and one-time transition tax in its 2017 year end income tax provision in accordance with its understanding of the 2017 Act and guidance available and, as a result, recorded a $272 tax charge in the fourth quarter of 2017, the period in which the legislation was enacted.

In 2018, the Company included a $59 tax charge in income from continuing operations as a result of finalizing its accounting for the 2017 Tax Act in accordance with SAB 118. This charge primarily related to a $16 charge for the one-time transition tax and a $43 charge to update deferred tax balances.

The components of net deferred tax assets and liabilities were as follows:

(1)Deferred tax assets with no expiration may still have annual limitations on utilization.

(2)Other represents deferred tax assets whose expiration is dependent upon the reversal of the underlying temporary difference.

(3)A substantial amount of Other deferred tax assets relates to employee benefits that will become deductible for tax purposes in jurisdictions with unlimited expiration over an extended period of time as contributions are made to employee benefit plans and payments are made to retirees.

The total deferred tax asset (net of valuation allowance) is supported by projections of future taxable income exclusive of reversing temporary differences (15%) and taxable temporary differences that reverse within the carryforward period (85%).

Table of Contents

Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not (greater than 50%) that a tax benefit will not be realized. In evaluating the need for a valuation allowance, management considers all potential sources of taxable income, including income available in carryback periods, future reversals of taxable temporary differences, projections of taxable income, and income from tax planning strategies, as well as all available positive and negative evidence. Positive evidence includes factors such as a history of profitable operations, projections of future profitability within the carryforward period, including from tax planning strategies, and Howmet’s experience with similar operations. Existing favorable contracts and the ability to sell products into established markets are additional positive evidence. Negative evidence includes items such as cumulative losses, projections of future losses, or carryforward periods that are not long enough to allow for the utilization of a deferred tax asset based on existing projections of income. Deferred tax assets for which no valuation allowance is recorded may not be realized upon changes in facts and circumstances, resulting in a future charge to establish a valuation allowance. Existing valuation allowances are re-examined under the same standards of positive and negative evidence. If it is determined that it is more likely than not that a deferred tax asset will be realized, the appropriate amount of the valuation allowance, if any, is released. Deferred tax assets and liabilities are also remeasured to reflect changes in underlying tax rates due to law changes and the granting and lapse of tax holidays.

In 2018, the Company made a final accounting policy election to apply a tax law ordering approach when considering the need for a valuation allowance on net operating losses expected to offset GILTI income inclusions. Under this approach, reductions in cash tax savings are not considered as part of the valuation allowance assessment. Instead, future GILTI inclusions are considered a source of taxable income that support the realizability of deferred tax assets.

Howmet’s foreign tax credits in the United States have a 10-year carryforward period with expirations ranging from 2021 to 2029 (as of December 31, 2020). Valuation allowances were initially established in prior years on a portion of the foreign tax credit carryforwards, primarily due to insufficient foreign source income to allow for full utilization of the credits within the expiration period. After consideration of all available evidence including potential tax planning strategies, an incremental valuation allowance of $46 was recognized in 2018. No additional valuation allowance was recorded in 2020 and 2019 as the Company intends to deduct, rather than credit, foreign taxes. Foreign tax credits of $88 and $8 expired at the end of 2019 and 2018, respectively, resulting in a corresponding decrease to the valuation allowance. The valuation allowance was also reduced by $113 in 2019 as a result of the Company filing amended tax returns to deduct foreign taxes that were previously claimed as a U.S. foreign tax credit. At December 31, 2020, the cumulative amount of the valuation allowance was $216. The need for this valuation allowance will be reassessed on a continuous basis in future periods and, as a result, the allowance may increase or decrease based on changes in facts and circumstances.

In 2020, the Company reversed $1 of valuation allowance recorded in 2019 related to capital losses utilized in the 2019 tax return. The Company also recorded a valuation allowance of $9 related to capital investments in 2019. Capital losses can only offset capital gain income. Howmet does not anticipate sufficient future sources of capital gain income to support the utilization future capital losses on these investments. The need for valuation allowances against capital investments will be reassessed on a continuing basis.

The Company recorded a $20 increase and $11 decrease to U.S. state valuation allowances in 2020 and 2019, respectively. After weighing all available positive and negative evidence, the Company determined the adjustments based on the underlying net deferred tax assets that were more likely than not realizable based on projected taxable income. Changes in fully reserved U.S. state tax losses, credits and other deferred tax assets resulting from expirations, audit adjustments, tax rate, and tax law changes also resulted in a corresponding $58 decrease and $5 increase in the valuation allowance in 2020 and 2019, respectively. Valuation allowances of $609 remain against state deferred tax assets expected to expire before utilization. The need for valuation allowances against state deferred tax assets will be reassessed on a continuous basis in future periods and, as a result, the allowance may increase or decrease based on changes in facts and circumstances.

In 2020, the Company increased a valuation allowance by $104 as a result of releasing a tax reserve following a favorable Spanish tax case decision. In 2018, the Company had reduced a valuation allowance by $92 as a result of increasing a tax reserve for unrecognized tax benefits related to the same Spanish tax case. The valuation allowance reduction was partially offset by a $20 charge with respect to losses no longer supported by reversing temporary differences. The Company also recorded an additional valuation allowance of $61 in 2018, which offset a deferred tax asset recorded for additional losses reported on the Spanish tax return related to the Alcoa Inc. Separation Transaction that are not more likely than not to be realized.

As a result of the 2017 Act, the non-previously taxed post-1986 foreign earnings and profits (calculated based on U.S. tax principles) of certain U.S.-owned foreign corporations has been subject to U.S. tax under the one-time transition tax provisions. The 2017 Act also created a new requirement that certain income earned by foreign subsidiaries, GILTI, must be included in the gross income of the U.S. shareholder. The 2017 Act also established the Base Erosion and Anti-Abuse Tax ("BEAT"). In the first quarter of 2018, the Company made a final accounting policy election to treat taxes due from future inclusions in U.S. taxable income related to GILTI as a current period expense when incurred. Howmet has estimated a GILTI inclusion for 2020, 2019, and 2018 and recorded tax expense accordingly. Howmet does not anticipate being subject to BEAT for these years.

Foreign U.S. GAAP earnings that have not otherwise been subject to U.S. tax, will generally be exempt from future U.S. tax under the 2017 Act when distributed. Such distributions, as well as distributions of previously taxed foreign earnings, could potentially be subject to U.S. state tax in certain states, and foreign withholding taxes. Foreign currency gains/losses related to the translation of previously taxed earnings from functional currency to U.S. dollars could also be subject to U.S. tax when distributed. At this time, Howmet has no plans to distribute such earnings in the foreseeable future. If such earnings were to be distributed, Howmet would expect the potential U.S. state tax and withholding tax impacts to be immaterial and the potential deferred tax liability associated with future foreign currency gains to be impracticable to determine.

Howmet and its subsidiaries file income tax returns in the U.S. federal jurisdiction and various states and foreign jurisdictions. With a few minor exceptions, Howmet is no longer subject to income tax examinations by tax authorities for years prior to 2011. All U.S. tax years prior to 2020 have been audited by the Internal Revenue Service. Various state and foreign jurisdiction tax authorities are in the process of examining the Company’s income tax returns for various tax years through 2019.

A reconciliation of the beginning and ending amount of unrecognized tax benefits (excluding interest and penalties) was as follows:

Balance at end of year	$	2	$	176	$	148

For all periods presented, a portion of the balance pertains to state tax liabilities, which are presented before any offset for federal tax benefits. The effect of unrecognized tax benefits, if recorded, that would impact the annual effective tax rate for 2020, 2019, and 2018 would be approximately 1%, 36%, and 11%, respectively, of pre-tax book income. Howmet does not anticipate that changes in its unrecognized tax benefits will have a material impact on the Statement of Consolidated Operations during 2021.

It is Howmet’s policy to recognize interest and penalties related to income taxes as a component of the Provision for income taxes on the accompanying Statement of Consolidated Operations. Howmet recognized interest of $2, $6, and $22 in 2020, 2019, and 2018, respectively. Due to the expiration of the statute of limitations, settlements with tax authorities, reductions in prior accruals and refunded overpayments, Howmet recognized interest income of $25, $0, and $1 in 2020, 2019, and 2018, respectively. As of December 31, 2020, 2019, and 2018, the amount accrued for the payment of interest and penalties was $2, $23, and $21, respectively.

Stock-Based Compensation

Howmet has a stock-based compensation plan under which stock options and/or restricted stock unit awards are granted in the first half of each year to eligible employees. Stock options are granted at the closing market price of Howmet’s common stock on the date of grant and typically vest over a three-year service period (1/3 each year) with a ten-year contractual term. Restricted stock unit awards typically vest over a three-year service period from the date of grant. As part of Howmet’s stock-based compensation plan design, individuals who are retirement-eligible have a six-month requisite service period in the year of grant. Certain of the restricted stock unit awards include performance and market conditions and are granted to certain eligible employees. In 2020 and 2019, performance stock awards were granted to a senior executive that vest either based on achievement of the Arconic Inc. Separation Transaction (see Note C for further details) or the achievement of certain stock price thresholds. For performance stock awards granted to other employees in 2020, the final number of shares earned will be based on Howmet’s achievement of profitability targets over the respective performance periods and will be earned at the end of the third year. Performance stock awards granted in the first quarter of 2019 were converted to restricted stock unit awards (at target), in order to address the pending Arconic Inc. Separation Transaction. For performance stock awards granted in 2018, in order to address the pending Arconic Inc. Separation Transaction, the final number of shares earned will be based on Howmet’s achievement of sales and profitability targets over performance periods in 2018 and 2019. Additionally, the 2020 and 2018 performance stock awards will be scaled by a total shareholder return ("TSR") multiplier, which depends upon relative performance against the TSRs of a group of peer companies.

In conjunction with their employment agreements, certain current and former executives were granted cash bonus awards based on the achievement of certain stock price thresholds. These awards are liability classified and were marked-to-market each quarter using a Monte Carlo simulation. The stock price thresholds have been fully reached. The cash payment of $23 will occur in 2021 in accordance with the terms of the agreements.

In 2020, 2019, and 2018, Howmet recognized stock-based compensation expense of $46 ($42 after-tax), $69 ($63 after-tax), and $40 ($31 after-tax), respectively. Senior executive performance awards granted in April 2020 were modified in June 2020, resulting in incremental compensation expense of $12, which will be amortized over the remaining service period ending April 1, 2023. Additionally, the effect of the Arconic Inc. Separation Transaction was a modification of the original stock options and restricted stock award units. The modifications were designed with the intention that the intrinsic value of the stock option or stock award were the same both previous to and after the adjustments. An immaterial charge was recorded to Restructuring and other charges related to the modification.

Over 95% of compensation expense recorded in 2020 relates to restricted stock unit awards. Cash bonus awards of $2 and $21 were recorded in 2020 and 2019, respectively. Of the remaining stock-based compensation expense in 2019, more than 95% relates to restricted stock unit awards. The expense related to restricted stock unit awards in 2018 was approximately 80%. No stock-based compensation expense was capitalized in any of those years. Stock-based compensation expense was reduced by $3 in 2019 for certain executive pre-vest cancellations which were recorded in Restructuring and other charges within the Statement of Consolidated Operations. At December 31, 2020, there was $51 (pre-tax) of unrecognized compensation expense related to non-vested stock option grants and non-vested restricted stock unit award grants. This expense is expected to be recognized over a weighted average period of 1.8 years.

Table of Contents

Stock-based compensation expense is based on the grant date fair value of the applicable equity grant. For restricted stock unit awards, the fair value was equivalent to the closing market price of Howmet’s common stock on the date of grant. The weighted average grant date fair value of the 2020 performance stock awards with a market condition scaled by a TSR multiplier was $21.33, and the weighted average grant date fair value of the April 2020 senior executive performance stock awards with a market condition (achievement of certain stock price thresholds) was $2.57. The weighted average grant date fair value of the 2019 performance stock awards with a market condition (achievement of certain stock price thresholds) was $11.93. The grant date fair value of the 2018 performance stock awards containing a market condition (scaled by TSR multiplier) was $20.25. The 2020, 2019 and 2018 performance awards were valued using a Monte Carlo model. A Monte Carlo simulation uses assumptions of stock price behavior to estimate the probability of satisfying market conditions and the resulting fair value of the award. The risk-free interest rate (0.3% in 2020, 1.6% in 2019 and in 2.7% 2018) was based on a yield curve of interest rates at the time of the grant based on the remaining performance period. In 2020 volatility was estimated using a blended rate of Howmet's historical volatility and a peer-based volatility (48.3%) due to the Arconic Inc. Separation Transaction and the related changes in the nature of the business. In 2019 volatility was estimated using implied and historical volatility (33.4%). Because of limited historical information due to the Alcoa Inc. Separation Transaction, 2018 volatility (32.0%) was estimated using implied volatility, and the representative price return approach, which uses price returns of comparable companies, was used to develop a correlation assumption. For stock options, the fair value was estimated on the date of grant using a lattice-pricing model, which generated a result of $9.79 per option in 2018. There were no stock options issued in 2020 or 2019. The lattice-pricing model uses a number of assumptions to estimate the fair value of a stock option, including a risk-free interest rate, dividend yield, volatility, exercise behavior, and contractual life. The following paragraph describes in detail the assumptions used to estimate the fair value of stock options granted in 2018.

The risk-free interest rate (2.5%) was based on a yield curve of interest rates at the time of the grant based on the contractual life of the option. The dividend yield (0.9%) was based on a one-year average. Volatility (34.0%) was based on comparable companies and implied volatilities over the term of the option. Howmet utilized historical option forfeiture data to estimate annual post-vesting forfeitures (6%). Exercise behavior (61%) was based on a weighted average exercise ratio (exercise patterns for grants issued over the number of years in the contractual option term) of an option’s intrinsic value resulting from historical employee exercise behavior. Based upon the other assumptions used in the determination of the fair value, the life of an option (6.0) was an output of the lattice-pricing mod. The activity for stock options and stock awards during 2020 was as follows (options and awards in millions):


	Stock options			Stock awards

(2)As a result of the Arconic Inc. Separation Transaction, all stock options and stock awards relating to Howmet employees were adjusted to reflect the Arconic Inc. Separation Transaction.

As of December 31, 2020, the number of stock options outstanding had a weighted average remaining contractual life of 2.9 years and a total intrinsic value of $18. Additionally, 3.1 million of the stock options outstanding were fully vested and exercisable and had a weighted average remaining contractual life of 2.8 years, a weighted average exercise price of $24.32, and a total intrinsic value of $18 as of December 31, 2020. In 2020, 2019, and 2018, the cash received from stock option exercises was $33, $56, and $16 and the total tax benefit realized from these exercises was $3, $4, and $2, respectively. The total intrinsic value of stock options exercised during 2020, 2019, and 2018 was $14, $17, and $7, respectively.

K. Earnings Per Share

Basic earnings per share ("EPS") amounts are computed by dividing earnings (loss), after the deduction of preferred stock dividends declared, by the average number of common shares outstanding. Diluted EPS amounts assume the issuance of common stock for all potentially dilutive share equivalents outstanding.

The information used to compute basic and diluted EPS attributable to Howmet common shareholders was as follows (shares in millions):

M. Receivables

Sale of Receivables Program

The Company has two accounts receivables securitization arrangements.

The first is an arrangement with financial institutions to sell certain customer receivables without recourse on a revolving basis ("Receivables Sale Program"). The sale of such receivables is completed using a bankruptcy remote special purpose entity, which is a consolidated subsidiary of the Company. This arrangement historically provided up to a maximum funding of $400 for receivables sold. The Company maintains a beneficial interest, or a right to collect cash, on the sold receivables that have not been funded (deferred purchase program receivable). In the first quarter of 2020, the Company entered into an amendment to remove subsidiaries of the GRP business from the sale of receivables program in preparation for the Arconic Inc. Separation Transaction and repurchased the remaining $282 unpaid receivables of GRP customers in a non-cash transaction by reducing the amount of the deferred purchase program receivable. This amendment also reduced the maximum funding for receivables sold to $300. Effective September 30, 2020, the concentration limit of one customer may be reduced at the discretion of the financial institutions or automatically upon the downgrade of its debt rating as defined in the Receivables Sale Program agreement. A reduction in the customer's concentration limit would reduce the eligible receivable funding base thereby reducing the amount of future draws available and may also require repayment of a portion of existing draws.

The Company had net cash repayments totaling $146 ($207 in draws and $353 in repayments) in 2020 and net cash repayments totaling $0 ($600 in draws and $600 in repayments) in 2019.

As of December 31, 2020, and 2019, the deferred purchase program receivable was $12 and $246, respectively, which was included in Other receivables on the accompanying Consolidated Balance Sheet. The deferred purchase program receivable is reduced as collections of the underlying receivables occur; however, as this is a revolving program, the sale of new receivables will result in an increase in the deferred purchase program receivable. The Company services the customer receivables for the financial institutions at market rates; therefore, no servicing asset or liability was recorded.

On April 14, 2020, the Company’s credit rating was downgraded by Moody’s Investors Service, Inc., which resulted in a termination event under the provisions of the Receivables Sale Program agreement for which a waiver was obtained. This termination event under the Receivables Sale Program is not an event of default under the Company’s other financing and commercial agreements, including the Credit Agreement. On May 5, 2020, an amendment to the Receivables Sale Program was executed that cured the termination event.

Cash receipts from customer payments on sold receivables (which are cash receipts on the underlying trade receivables that have been previously sold in this program) as well as cash receipts and cash disbursements from draws and repayments under the program are presented as cash receipts from sold receivables within investing activities in the Statement of Consolidated Cash Flows.

The second arrangement is one in which the Company, through a wholly-owned special purpose entity (“SPE”), entered into an receivables purchase agreement (the “Receivables Purchase Agreement”) on June 30, 2020 such that the SPE may sell certain receivables to financial institutions until the earlier of June 30, 2021 or a termination event. The Receivables Purchase Agreement also contains customary representations and warranties, as well as affirmative and negative covenants. Pursuant to the Receivables Purchase Agreement, the Company does not maintain effective control over the transferred receivables, and therefore accounts for these transfers as sales of receivables.

The SPE sold $165 of its receivables without recourse and received cash funding under this program in 2020, resulting in derecognition of the receivables from the Company’s consolidated balance sheets (of which $46 remained outstanding from the customer at December 31, 2020 and $0 was in the program at December 31, 2019). Cash received from collections of sold receivables is used by the SPE to fund additional purchases of receivables on a revolving basis, not to exceed $125, which is the aggregate maximum limit. As collateral against the sold receivables, the SPE maintains a certain level of unsold receivables, which was $33 at December 31, 2020. Costs associated with the sales of receivables are reflected in the Company’s Consolidated statements of operations for the periods in which the sales occur. Cash receipts from sold receivables under the Receivables Purchase Agreement are presented within operating activities in the Statement of Consolidated Cash Flows.

Table of Contents

The Company had accounts receivable securitization arrangements totaling $425 at December 31, 2020, of which $250 was drawn. The Company had accounts receivable securitization arrangements totaling $400 at December 31, 2019, of which $350 was drawn. The $100 reduction in the amount drawn resulted in a corresponding reduction in Cash and cash equivalents.

Other Customer Receivable Sales

In 2020, the Company sold $32 of a certain customer’s receivables in exchange for cash (of which $0 remained outstanding from the customer at December 31, 2020), the proceeds from which are presented in changes in receivables within operating activities in the Statement of Consolidated Cash Flows. The sale of these customer receivables partially offset the maximum funding reduction resulting from the Arconic Inc. Separation Transaction as well as customer concentration limits within the first accounts receivable securitization arrangement.

In 2020, the Company sold another customer’s receivables of $149 in exchange for cash (of which $50 remained outstanding from the customer at December 31, 2020), the proceeds from which are presented in changes in receivables within operating activities in the Statement of Consolidated Cash Flows. The sale of these customer receivables was undertaken to offset a change in the customer’s payment patterns (customer had been taking a discount for paying early).

Allowance for Doubtful Accounts

The following table details the changes in the allowance for doubtful accounts related to customer receivables and other receivables:


	Customer receivables						Other receivables
	2020		2019		2018		2020		2019		2018

Table of Contents

During the second quarter of 2019, the Company updated its five-year strategic plan and determined that there was a decline in the forecasted financial performance for the Disks asset group within the Engineered Products and Forgings segment at that time. As such, the Company evaluated the recoverability of the Disks asset group long-lived assets by comparing the carrying value to the undiscounted cash flows of the Disks asset group. The carrying value exceeded the undiscounted cash flows and therefore the Disks asset group long-lived assets were deemed to be impaired. The impairment charge was measured as the amount of carrying value in excess of fair value of the long-lived assets, with fair value determined using a DCF model and a combination of sales comparison and cost approach valuation methods including an estimate for economic obsolescence. The impairment charge of $428, of which $247 and $181 related to the Engine Products and Engineered Structures segments, respectively, recorded in the second quarter of 2019 impacted properties, plants, and equipment; intangible assets; and certain other noncurrent assets by $198, $197, and $33, respectively. The impairment charge was recorded in Restructuring and other charges in the Statement of Consolidated Operations in 2019.

Depreciation expense related to Properties, plants and equipment recorded in Provision for depreciation and amortization in the accompanying Statement of Consolidated Operations was $236, $234, and $253 for the years ended December 31, 2020, 2019 and 2018, respectively.

The principal amount of long-term debt maturing in each of the next five years is $361 in 2021, $476 in 2022, $0 in 2023, $1,250 in 2024, and $1,200 in 2025.

Public Debt. On January 15, 2021 the Company completed the early redemption of all the remaining $361 of its 5.400% Notes due in April 2021 (the “5.400% Notes”) at par and paid $5 in accrued interest. On an annual basis, the redemption of these Notes will decrease Interest expense, net by approximately $19.

On May 21, 2020, the Company completed a cash tender offer and redeemed $589 and $151 of principal amount of the 5.400% Notes and its 5.870% Notes due 2022, respectively. The amount of early tender premium and accrued interest and associated with the notes accepted for early settlement were $24 and $4, respectively, which was recorded in Interest expense, net during the second quarter ended June 30, 2020 and nine months ended September 30, 2020 in the Statement of Consolidated Operations.

On April 24, 2020, the Company completed an offering of $1,200 aggregate principal amount of 6.875% Notes due 2025, the proceeds of which have been used to fund the cash tender offers noted above and to pay related transaction fees, including applicable premiums and expenses, with the remaining amount to be used for general corporate purposes. The Company incurred deferred financing costs of $14 associated with the issuance in the second quarter of 2020.

On April 16, 2020, the Company filed a shelf registration statement on Form S-3 with the Securities and Exchange Commission, which became effective automatically (the “Shelf Registration Statement”). The Shelf Registration Statement allows for offerings of debt securities from time to time.

On April 6, 2020, the Company completed the early redemption of all $1,000 of its 6.150% Notes due 2020 (the "6.150% Notes") and the early partial redemption of $300 of its 5.400% Notes. Holders of the 6.150% Notes were paid an aggregate of $1,020 and holders of the 5.400% Notes were paid an aggregate of $315, plus accrued and unpaid interest up to, but not including, the redemption date. The Company incurred early termination premium and accrued interest of $35 and $17, respectively, which has been recorded in Interest expense, net during the second quarter ended June 30, 2020 and nine months ended September 30, 2020 in the Statement of Consolidated Operations.

On October 15, 2019, the 1.63% Convertible Notes matured in accordance with their terms and the Company repaid in cash the aggregate outstanding principal amount of $403 together with accrued and unpaid interest.

During the first quarter of 2018, the Company completed the early redemption of its remaining outstanding 5.72% Notes due in 2019, with aggregate principal amount of $500, for $518 in cash including accrued and unpaid interest. As a result, the Company recorded a charge of $19 in Interest expense in the accompanying Statement of Consolidated Operations for 2018 primarily for the premium paid on the early redemption of these notes in excess of their carrying value.

Table of Contents

The Company has the option to redeem certain of its Notes and Bonds in whole or part, at any time at a redemption price equal to the greater of principal amount or the sum of the present values of the remaining scheduled payments, discounted using a defined treasury rate plus a spread, plus in either case accrued and unpaid interest to the redemption date.

Credit Facilities. On July 25, 2014, Howmet entered into a Five-Year Revolving Credit Agreement with a syndicate of lenders and issuers named therein, which provides for a senior unsecured revolving credit facility (the “Credit Facility”). By an Extension Request and Amendment Letter dated as of June 5, 2015, the maturity date of the Credit Facility was extended to July 25, 2020. On September 16, 2016, Howmet entered into Amendment No. 1 to the Five-Year Revolving Credit Agreement to permit the Alcoa Inc. Separation Transaction and to amend certain terms of the Credit Agreement, including the replacement of the existing financial covenant with a leverage ratio and reduction of total commitments available from $4,000 to $3,000. On June 29, 2018, the Company entered into Amendment No. 2 (“Amendment No. 2”) to amend and restate the Five-Year Revolving Credit Agreement. The Five-Year Revolving Credit Agreement, as so amended and restated, is herein referred to as the “Credit Agreement.”

On March 4, 2020, the Company entered into Amendment No. 3 to the Credit Agreement. The amendment was entered into to permit the Arconic Inc. Separation Transaction and to amend certain terms of the Credit Agreement, including a change to the existing financial covenant and reduction of total commitments available from $3,000 to $1,500, effective April 1, 2020 and extended the maturity date from June 29, 2023 to April 1, 2025. The Company was required to maintain a ratio of Consolidated Net Debt (as defined in the Credit Agreement) to Consolidated EBITDA (as defined in the Credit Agreement) to be no greater than 3.50 to 1.00.

On June 26, 2020, the Company entered into Amendment No. 4 to the Credit Agreement to provide relief from its existing financial covenant through December 31, 2021 and reduce total commitment available from $1,500 to $1,000. The Company is required to maintain a ratio of Consolidated Net Debt to Consolidated EBITDA (as defined in the Credit Agreement) as of the end of each fiscal quarter for the period of the four fiscal quarters of the Company most recently ended, to be no greater than (i) 5.00 to 1.00 for any quarter ending on or prior to December 31, 2020, (ii) 5.25 to 1.00 for the quarter ending March 31, 2021, (iii) 5.00 to 1.00 for the quarter ending June 30, 2021, (iv) 4.50 to 1.00 for the quarter ending September 30, 2021, and (v) 4.00 to 1.00 for the quarter ending December 31, 2021. The ratio returns to 3.50 to 1.00 for all periods thereafter.

Under Amendment No. 4 to the Credit Agreement, during the covenant relief period from June 30, 2020 through December 31, 2021 (unless the Company ends the covenant relief period earlier in accordance with the amendment), common stock dividends and share repurchases are permitted only if no borrowings under the Credit Agreement are outstanding at the time and are limited to an aggregate amount of $100 through June 30, 2021, with such limit increasing by $150 to an aggregate amount of $250 after June 30, 2021 if the Consolidated Net Debt to Consolidated EBITDA ratio is no greater than 3.75 to 1.00. At December 31, 2020, the Company was in compliance with all covenants under the Credit Agreement. Availability under the Credit Agreement could be reduced in future periods if the Company fails to maintain the required ratios referenced above.

The Credit Agreement includes additional covenants, including, among others, (a) limitations on Howmet’s ability to incur liens securing indebtedness for borrowed money, (b) limitations on Howmet’s ability to consummate a merger, consolidation or sale of all or substantially all of its assets, and (c) limitations on Howmet’s ability to change the nature of its business.

The Credit Facility matures on April 1, 2025, unless extended or earlier terminated in accordance with the provisions of the Credit Agreement. Howmet may make two one-year extension requests during the term of the Credit Facility, subject to the lender consent requirements set forth in the Credit Agreement. Under the provisions of the Credit Agreement, Howmet will pay a fee of 0.30% per annum (based on Howmet’s current long-term debt ratings) of the total commitment to maintain the Credit Facility.

The Credit Facility is unsecured and amounts payable under it will rank pari passu with all other unsecured, unsubordinated indebtedness of Howmet. Borrowings under the Credit Facility may be denominated in U.S. dollars or euros. Loans will bear interest at a base rate or a rate equal to LIBOR, plus, in each case, an applicable margin based on the credit ratings of Howmet’s outstanding senior unsecured long-term debt. The applicable margin during the covenant relief period on base rate loans and LIBOR loans will be 1.20% and 2.20% per annum, respectively, through June 30, 2021; and 0.95% and 1.95% per annum, respectively, for the period from June 30, 2021 through December 31,2021, based on Howmet’s current long-term debt ratings. The applicable margin in 2022 and thereafter on base rate loans and LIBOR loans will be 0.70% and 1.70% per annum, respectively, based on Howmet’s current long-term debt ratings. The applicable margin during and after the covenant relief period is subject to change based on the Company’s long-term debt ratings. Loans may be prepaid without premium or penalty, subject to customary breakage costs.

The obligation of Howmet to pay amounts outstanding under the Credit Facility may be accelerated upon the occurrence of an “Event of Default” as defined in the Credit Agreement. Such Events of Default include, among others, (a) non-payment of obligations; (b) breach of any representation or warranty in any material respect; (c) non-performance of covenants and obligations; (d) with respect to other indebtedness in a principal amount in excess of $100, a default thereunder that causes such

Table of Contents

indebtedness to become due prior to its stated maturity or a default in the payment at maturity of any principal of such indebtedness; (e) the bankruptcy or insolvency of Howmet; and (f) a change in control of Howmet.

There were no amounts outstanding at December 31, 2020 and 2019, and no amounts were borrowed during 2020, 2019, or 2018 under the Credit Agreement.

In addition to the Credit Agreement, the Company had several other credit agreements that provided a borrowing capacity of $640 as of December 31, 2019, and all of which expired in 2020. The purpose of any borrowings under these credit arrangements was to provide for working capital requirements and for other general corporate purposes. The covenants contained in these arrangements were the same as the Credit Agreement. In 2020, nothing was borrowed or repaid under these arrangements. In 2019 and 2018, Howmet borrowed and repaid $400 and $600, respectively, under the respective credit arrangements. The weighted-average interest rate and weighted-average days outstanding of the respective borrowings during 2019 and 2018 were 3.7%, and 3.3%, respectively, and 49 days and 46 days, respectively.

Short-Term Debt. At December 31, 2020 and 2019, short-term debt was $14 and $31, respectively, substantially all of which related to accounts payable settlement arrangements with certain vendors and third-party intermediaries. These arrangements provide that, at the vendor’s request, the third-party intermediary advances the amount of the scheduled payment to the vendor, less an appropriate discount, before the scheduled payment date, and Howmet makes payment to the third-party intermediary on the date stipulated in accordance with the commercial terms negotiated with its vendors. Howmet records imputed interest related to these arrangements in Interest expense on the accompanying Statement of Consolidated Operations.

Commercial Paper. Howmet had no outstanding commercial paper at December 31, 2020 and 2019. In 2020 and 2019, Howmet did not issue commercial paper. In 2018, the average outstanding commercial paper was $49. Commercial paper matured at various times in 2018 and had an annual weighted average interest rate of 2.5% during 2018.

S. Other Financial Instruments

Fair Value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy distinguishes between (i) market participant assumptions developed based on market data obtained from independent sources (observable inputs) and (ii) an entity’s own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs). The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy are described below:

•Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

•Level 2 - Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates); and inputs that are derived principally from or corroborated by observable market data by correlation or other means.

•Level 3 - Inputs that are both significant to the fair value measurement and unobservable.

The carrying values of Cash and cash equivalents, Restricted cash, Derivatives, Noncurrent receivables, and Short-term debt included in the Consolidated Balance Sheet approximate their fair value. The Company holds exchange-traded fixed income securities which are considered available-for-sale securities that are carried at fair value which is based on quoted market prices which are classified in Level 1 of the fair value hierarchy. The fair value of Long-term debt, less amounts due within one year was based on quoted market prices for public debt and on interest rates that are currently available to Howmet for issuance of debt with similar terms and maturities for non-public debt. The fair value amounts for all Long-term debt were classified in Level 2 of the fair value hierarchy.


	2020				2019
December 31,	Carrying value		Fair value		Carrying value		Fair value
Long-term debt, less amounts due within one year	$	4,699	$	5,426	$	4,906	$	5,337

Restricted cash was $1, $55 (see Note U), and $6 in 2020, 2019, and 2018, respectively, and was recorded in Prepaid expenses and other current assets on the Consolidated Balance Sheet.

T. Cash Flow Information

Cash paid for interest and income taxes for both continuing and discontinued operations was as follows:


	2020		2019		2018
Interest, net of amounts capitalized	$	401	$	340	$	391
Income taxes, net of amounts refunded	$	(33)	$	122	$	74

The Company incurred capital expenditures which remain unpaid at December 31, 2020, 2019 and 2018 of $50, $133 and $188 respectively, which result in cash outflows for investing activities in subsequent periods.

U. Acquisitions and Divestitures

2020 Divestitures

On January 31, 2020, the Company reached an agreement to sell a small manufacturing plant within the Engineered Structures segment for $12 in cash and therefore was classified as held for sale. However, as the sale did not close, the Company changed the classification of the assets from held for sale to held for use and recorded these assets at their lower of carrying value (assuming no initial reclassification for held for sale was made) or fair value. The result was a $5 non-cash impairment in 2020 which was recorded in Restructuring and other charges in the Statement of Consolidated Operations.

2019 Divestitures

On May 31, 2019, the Company sold a small additive manufacturing facility within the Engineered Structures segment for $1 in cash, which resulted in a loss of $13 recorded in Restructuring and other charges in the Statement of Consolidated Operations in 2019.

On August 15, 2019, the Company sold inventories and properties, plants, and equipment related to a small energy business within the Engineered Structures segment for $13 in cash. The Company recognized a charge of $10 related to inventory impairment and recorded the charge in Cost of goods sold in the Statement of Consolidated Operations in 2019.

On December 1, 2019, the Company completed the sale of its forgings business in the United Kingdom (U.K.) for $64 in cash, which resulted in a loss on sale of $46 which was recorded in Restructuring and other charges in the Statement of Consolidated Operations in 2019. The Company settled certain post-closing adjustments which resulted in a $5 reduction in the purchase price and an additional loss of sale which was recorded in Restructuring and other charges in the Statement of Consolidated Operations in 2020. The sale remains subject to certain tax post-closing adjustments. Of the cash proceeds received, $53 was recorded as Restricted cash within Prepaid expenses and other current assets on the Consolidated Balance Sheet at December 31, 2019 as its use is subject to restriction by the U.K. pension authority until certain U.K. pension plan changes have been made and approved. The restriction on these proceeds was removed in the second quarter of 2020. The forgings business primarily produces steel, titanium, and nickel based forged components for aerospace, mining, and off-highway markets and its operating results and assets and liabilities were included in the Engine Products segment. This business generated third party sales of $116, and $126 in 2019 and 2018, and had 540 employees at the time of divestiture.

2018 Divestitures

On December 31, 2018, as part of the Company’s then ongoing strategy and portfolio review, Howmet completed the sale of its forgings business in Hungary to Angstrom Automotive Group LLC for $2, which resulted in a loss of $43 recorded in Restructuring and other charges in the Statement of Consolidated Operations in 2018. While owned by Howmet, the operating results and assets and liabilities of the business were included in the Engine Products segment. This business generated sales of $32 in 2018 and had 180 employees at the time of the divestiture.

V. Contingencies and Commitments

Contingencies

Environmental Matters. Howmet participates in environmental assessments and cleanups at more than 30 locations. These include owned or operating facilities and adjoining properties, previously owned or operating facilities and adjoining properties, and waste sites, including Superfund (Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA")) sites.

A liability is recorded for environmental remediation when a cleanup program becomes probable and the costs can be reasonably estimated. As assessments and cleanups proceed, the liability is adjusted based on progress made in determining the extent of remedial actions and related costs. The liability can change substantially due to factors such as the nature and extent of contamination, changes in remedial requirements, and technological changes, among others.

Table of Contents

The Company's remediation reserve balance was $10 at December 31, 2020 and $8 at December 31, 2019 recorded in Other noncurrent liabilities and deferred credits in the Consolidated Balance Sheet (of which $5 and $3, respectively, were classified as a current liability), and reflects the most probable costs to remediate identified environmental conditions for which costs can be reasonably estimated. Payments related to remediation expenses applied against the reserve were $2 in 2020 and $3 in 2019 and included expenditures currently mandated, as well as those not required by any regulatory authority or third party.

Included in annual operating expenses are the recurring costs of managing hazardous substances and environmental programs. These costs are estimated to be less than 1% of Cost of goods sold.

The Company previously reported on a remediation project related to the Grasse River, which is adjacent to the Massena West, New York plant site that is now part of Arconic Corporation. Pursuant to the Separation and Distribution Agreement between the Company and Arconic Corporation, dated as of March 31, 2020, Arconic Corporation agreed to assume and indemnify the Company against potential liabilities associated with the Grasse River remediation project. Therefore, the Company will no longer report on the Grasse River matter unless and until some event in the future causes it to become material and reportable.

Tax. As previously reported, in July 2013, following a Spanish corporate income tax audit covering the 2006 through 2009 tax years, an assessment was received mainly disallowing certain interest deductions claimed by a Spanish consolidated tax group owned by the Company. The Company appealed this assessment to Spain's Central Tax Administrative Court, and subsequently to Spain's National Court, each of which was denied.

The Company then appealed the decision to the Supreme Court of Spain. In November 2020, the Supreme Court of Spain rendered a decision in favor of the taxpayer, removing the assessment in its entirety. The decision is final and cannot be further appealed.

As a result of the favorable decision, in the fourth quarter of 2020, the Company released an income tax reserve, including interest, of $64 (€54), which was recorded in Provision (benefit) for income taxes in the Consolidated Statement of Operations, that was previously established in the third quarter of 2018. In addition, the Company reversed a combined indemnification receivable of $53 (€45) for Alcoa Corporation's 49% share and Arconic Corporation's 33.66% share of the total reserve, which was recorded in Other expense (income), net in the Consolidated Statement of Operations, that were previously established pursuant to the October 31, 2016 and March 31, 2020 Tax Matters Agreements, respectively. As of the end of 2020, the Company no longer has a balance recorded for this matter.

Reynobond PE. Prior to the Arconic Inc. Separation Transaction on April 1, 2020, the Company was known as Arconic Inc. References to “Arconic Inc.” in this “Reynobond PE” section refer to Arconic Inc. only and do not include its subsidiaries, except as otherwise stated.

On June 13, 2017, the Grenfell Tower in London, U.K. caught fire resulting in fatalities, injuries and damage. A French subsidiary of Arconic Inc., Arconic Architectural Products SAS ("AAP SAS") (now a subsidiary of Arconic Corporation as a result of the Arconic Inc. Separation Transaction), supplied a product, Reynobond PE, to its customer, a cladding system fabricator, which used the product as one component of the overall cladding system on Grenfell Tower. The fabricator supplied its portion of the cladding system to the façade installer, who then completed and installed the system under the direction of the general contractor. Neither Arconic Inc. nor AAP SAS was involved in the design or installation of the system used at the Grenfell Tower, nor did it have a role in any other aspect of the building’s refurbishment or original design. Regulatory investigations into the overall Grenfell Tower matter are being conducted, including a criminal investigation by the London Metropolitan Police Service (the “Police”), a Public Inquiry by the British government and a consumer protection inquiry by a French public authority. The Public Inquiry was announced by the U.K. Prime Minister on June 15, 2017 and subsequently was authorized to examine the circumstances leading up to and surrounding the Grenfell Tower fire in order to make findings of fact and recommendations to the U.K. Government on matters such as the design, construction and modification of the building, the role of relevant public authorities and contractors, the implications of the fire for the adequacy and enforcement of relevant regulations, arrangements in place for handling emergencies and the handling of concerns from residents, among other things. Hearings for Phase 1 of the Public Inquiry began on May 21, 2018 and concluded on December 12, 2018. Phase 2 hearings of the Public Inquiry began in early 2020, following which a final report will be written and subsequently published. AAP SAS is participating as a Core Participant in the Public Inquiry and is also cooperating with the ongoing parallel investigation by the Police. Arconic Corporation does not sell and Arconic Inc. previously stopped selling the PE product for architectural use on buildings. Given the preliminary nature of these investigations and the uncertainty of potential future litigation, the Company cannot reasonably estimate at this time the likelihood of an unfavorable outcome or the possible loss or range of losses in the event of an unfavorable outcome.

Pursuant to the Separation and Distribution Agreement, dated as of March 31, 2020, Arconic Corporation agreed to indemnify the Company for certain liabilities and the Company agreed to indemnify Arconic Corporation for certain liabilities. As a result of the Arconic Inc. Separation Transaction, Arconic Corporation holds the building and construction systems businesses previously held by the Company and AAP SAS is a subsidiary of Arconic Corporation; accordingly, Arconic Corporation has

agreed to assume and indemnify the Company against potential liabilities associated with the June 13, 2017 fire at the Grenfell Tower in London, U.K., including the following legal proceedings in which Arconic Inc. and/or its then directors were named as parties:

On December 23, 2020, claimant groups comprised of survivors and estates of decedents of the Grenfell Tower fire filed claims in the U.K. arising from that fire, against 23 defendants, including Howmet Aerospace Inc., AAP SAS, Arconic Corporation, the Royal Borough of Kensington and Chelsea, the Royal Borough of Kensington and Chelsea Tenant Management Organisation Ltd, the London Fire Commissioner, the UK Home Office, The Ministry of Housing, Communities and Local Government, Rydon Maintenance Ltd, Celotex Ltd, Saint-Gobain Construction Products UK Limited, Kingspan Insulation Limited, Kingspan Group PLC, Studio E Architects Ltd (in liquidation), Harley Facades Ltd, Harley Curtain Wall Limited (in liquidation), CEP Architectural Facades Ltd, Exova (U.K.) Ltd, CS Stokes & Associates Ltd, Artelia Projects UK Limited, Whirlpool UK Appliances Limited, Whirlpool Company Polska Sp.z.o.o. and Whirlpool Corporation. The Company has not yet been served with the claims and, therefore, currently does not have information regarding claimants’ substantive allegations or the relief that claimants seek.

Behrens et al. v. Arconic Inc. et al. On June 6, 2019, 247 plaintiffs comprised of survivors and estates of decedents of the Grenfell Tower fire filed a complaint against “Arconic Inc., Alcoa Inc. and Arconic Architectural Products, LLC” (collectively, for purposes of the description of such proceeding, the “Arconic Defendants”), as well as Saint-Gobain Corporation, d/b/a Celotex, and Whirlpool Corporation alleging claims under Pennsylvania state law for products liability and wrongful death related to the fire. In particular, the plaintiffs allege that the Arconic Defendants knowingly supplied a dangerous product ("Reynobond PE") for installation on the Grenfell Tower despite knowing that Reynobond PE was unfit for use above a certain height. Plaintiffs seek monetary damages exceeding $75,000 for each plaintiff. The case was removed to the United States District Court for the Eastern District of Pennsylvania. Defendants moved to dismiss the case on numerous grounds, including forum non conveniens. Defendant Saint-Gobain Corporation was subsequently voluntarily dismissed from the case. On September 16, 2020, the court issued an order granting the remaining defendants’ motion to dismiss on forum non conveniens grounds, subject to certain conditions, determining that the United Kingdom, and not the United States, is the appropriate place for plaintiffs to bring their case. Plaintiffs subsequently filed a motion for reconsideration, which the court denied on November 23, 2020. Plaintiffs are appealing the judgment; the Arconic Defendants are cross-appealing one of the conditions.

Howard v. Arconic Inc. et al. A purported class action complaint related to the Grenfell Tower fire was filed on August 11, 2017 in the United States District Court for the Western District of Pennsylvania against Arconic Inc. and Klaus Kleinfeld. A related purported class action complaint was filed in the United States District Court for the Western District of Pennsylvania on September 15, 2017, under the caption Sullivan v. Arconic Inc. et al., against Arconic Inc., three former Arconic Inc. executives, several current and former directors, and certain banks. Howard and Sullivan were subsequently consolidated and the lead plaintiffs in the consolidated purported class action filed a consolidated amended complaint alleging violations of the federal securities laws and seeking, among other things, unspecified compensatory damages and an award of attorney and expert fees and expenses. After the court granted the defendants’ motion to dismiss in full, the lead plaintiffs filed a second amended complaint, and all defendants have moved to dismiss the second amended complaint.

Raul v. Albaugh, et al. On June 22, 2018, a derivative complaint was filed nominally on behalf of Arconic Inc. by a purported Arconic Inc. stockholder against the then members of Arconic Inc.’s Board of Directors and Klaus Kleinfeld and Ken Giacobbe, naming Arconic Inc. as a nominal defendant, in the United States District Court for the District of Delaware. The complaint raises similar allegations as the consolidated amended complaint and second amended complaint in Howard, as well as allegations that the defendants improperly authorized the sale of Reynobond PE for unsafe uses, and asserts claims under federal securities laws and Delaware state law. The case has been stayed until the final resolution of the Howard case, the Grenfell Tower Public Inquiry in London, and the investigation by the Police.

While there can be no assurances regarding the ultimate resolution of these matters, Arconic Corporation has agreed to assume and indemnify the Company against potential liabilities associated with them.

Stockholder Demands. Prior to the Arconic Inc. Separation Transaction, the Board of Directors also received letters, purportedly sent on behalf of stockholders, reciting allegations similar to those made in the federal court lawsuits and demanding that the Board authorize the Company to initiate litigation against members of management, the Board and others. The Board of Directors appointed a Special Litigation Committee of the Board to review, investigate, and make recommendations to the Board regarding the appropriate course of action with respect to these stockholder demand letters. On May 22, 2019, the Special Litigation Committee, following completion of its investigation into the claims demanded in the demand letters, recommended to the Board that it reject the demands to authorize commencement of litigation. On May 28, 2019, the Board adopted the Special Litigation Committee’s findings and recommendations and rejected the demands that it authorize commencement of actions to assert the claims set forth in the demand letters.

Lehman Brothers International (Europe) ("LBIE") Claim. On June 26, 2020, LBIE filed formal proceedings against two Firth Rixson entities ("Firth") in the High Court of Justice, Business and Property Courts of England and Wales. The proceedings relate to interest rate swap transactions that Firth entered into with LBIE in 2007 to 2008. In 2008, LBIE commenced insolvency proceedings, an event of default under the agreements, rendering LBIE unable to meet its obligations under the swaps and suspending Firth’s payment obligations. In the Court proceedings, LBIE seeks a declaration that Firth has a contractual obligation to pay the amounts owing to LBIE under the agreements. The parties filed position papers on July 24, 2020 and October 19, 2020 (LBIE) and September 21, 2020 (Firth). A virtual hearing in this matter occurred on January 13 and 14, 2021 in London. A decision is expected in three to six months. The resolution of this matter is not probable as of December 31, 2020.

Other. In addition to the matters discussed above, various other lawsuits, claims, and proceedings have been or may be instituted or asserted against the Company, including those pertaining to environmental, product liability, safety and health, employment, tax and antitrust matters. While the amounts claimed in these other matters may be substantial, the ultimate liability cannot currently be determined because of the considerable uncertainties that exist. Therefore, it is possible that the Company’s liquidity or results of operations in a period could be materially affected by one or more of these other matters. However, based on facts currently available, management believes that the disposition of these other matters that are pending or asserted will not have a material adverse effect, individually or in the aggregate, on the results of operations, financial position or cash flows of the Company.

Commitments

Purchase Obligations. Howmet has entered into purchase commitments for raw materials, energy and other goods and services, which total $210 in 2021, $31 in 2022, $10 in 2023, $8 in 2024, $0 in 2025, and $0 thereafter.

Operating Leases. See Note Q for the operating lease future minimum contractual obligations.

Guarantees. At December 31, 2020, Howmet had outstanding bank guarantees related to tax matters, outstanding debt, workers’ compensation, environmental obligations, energy contracts, and customs duties, among others. The total amount committed under these guarantees, which expire at various dates between 2021 and 2040 was $44 at December 31, 2020.

Pursuant to the Separation and Distribution Agreement between Howmet and Alcoa Corporation, Howmet was required to provide certain guarantees for Alcoa Corporation, which had a fair value of $12 and $9 at December 31, 2020 and 2019, respectively, and were included in Other noncurrent liabilities and deferred credits on the accompanying Consolidated Balance Sheet. The Company was required to provide a guarantee up to an estimated present value amount of approximately $1,398 and $1,353 at December 31, 2020 and December 31, 2019, respectively. For this guarantee, subject to its provisions, the Company is secondarily liable in the event of a payment default by Alcoa Corporation. The Company currently views the risk of an Alcoa Corporation payment default on its obligations under the contract to be remote.

Letters of Credit. The Company has outstanding letters of credit, primarily related to workers’ compensation, environmental obligations and leasing obligations. The total amount committed under these letters of credit, which automatically renew or expire at various dates, mostly in 2021, was $105 at December 31, 2020.

Pursuant to the Separation and Distribution Agreements between the Company and Arconic Corporation and between the Company and Alcoa Corporation, the Company is required to retain letters of credit of $53 that had previously been provided related to the Company, Arconic Corporation, and Alcoa Corporation workers’ compensation claims which occurred prior to the respective separation transactions of April 1, 2020 and November 1, 2016. Arconic Corporation and Alcoa Corporation workers’ compensation and letters of credit fees paid by the Company are being proportionally billed to and are being reimbursed by Arconic Corporation and Alcoa Corporation, respectively. Also, the Company was required to provide letters of credit for certain Arconic Corporation environmental obligations and, as a result, the Company has $29 of outstanding letters of credit relating to liabilities (which are included in the $105 in the above paragraph). $13 of these outstanding letters of credit are pending cancellation and will be deemed cancelled once returned by the beneficiary. Arconic Corporation has issued surety bonds to cover these environmental obligations. Arconic Corporation is being billed for these letter of credit fees paid by the Company and will reimburse the Company for any payments made under these letters of credit.

Surety Bonds. The Company has outstanding surety bonds primarily related to tax matters, contract performance, workers’ compensation, environmental-related matters, and customs duties. The total amount committed under these surety bonds, which expire and automatically renew at various dates, primarily in 2021, was $43 at December 31, 2020.

Pursuant to the Separation and Distribution Agreements between the Company and Arconic Corporation and between the Company and Alcoa Corporation, the Company is required to provide surety bonds of $26 (which are included in the $43 in the above paragraph) that had previously been provided related to the Company, Arconic Corporation, and Alcoa Corporation workers’ compensation claims which occurred prior to the respective separation transactions of April 1, 2020 and November 1,
