Risks Related to the Separation

•We may not achieve some or all of the expected benefits of the separation.
•In connection with the separation into two public companies, we and Howmet agreed to indemnify each other for certain liabilities. If we are required to pay under these indemnities to Howmet, our financial results could be negatively impacted. The Howmet indemnities may not be sufficient to hold us harmless from the full amount of liabilities for which Howmet has been allocated responsibility, and Howmet may not be able to satisfy its indemnification obligations in the future.
•Howmet may fail to perform under various transaction agreements that were executed as part of the separation.
•If the distribution, together with certain related transactions, does not qualify as a transaction that is generally tax-free for U.S. federal income tax purposes, we, as well as Howmet and Howmet’s stockholders, could be subject to significant tax liabilities, and, in certain circumstances, we could be required to indemnify Howmet for material taxes and other related amounts pursuant to indemnification obligations under the tax matters agreement.

Item 1. Business.
Overview
Arconic Corporation ("Arconic" or the "Company") is a global leader in manufacturing aluminum sheet, plate, extrusions and architectural products and systems, serving primarily the ground transportation, aerospace, building and construction, industrial, and packaging end markets. We maintain a leadership position in our targeted markets through our global footprint of 21 primary manufacturing facilities, as well as various sales and service facilities, located across North America, Europe, the United Kingdom, Russia and China.
Arconic was previously a part of Arconic Inc., which was renamed Howmet Aerospace Inc. on April 1, 2020 in connection with the separation described below under “--The Separation Transaction.” Arconic Inc. was previously part of Alcoa Inc. (renamed Arconic Inc. in 2016).
The Separation Transaction
On April 1, 2020, Arconic completed its separation from Arconic Inc. and became an independent, publicly traded company. Arconic’s business includes the rolled aluminum products, aluminum extrusions, and architectural products operations that were formerly part of ParentCo. Howmet continues to own its engine products, engineered structures, fastening systems, and forged wheels operations.
Upon completion of the distribution, Arconic and Howmet became separate companies with separate management teams and separate boards of directors. Prior to the distribution, Arconic and ParentCo entered into a separation agreement. In connection with the separation, we entered into various other agreements to (i) implement the legal and structural separation between the two companies; (ii) govern the relationship between Arconic and Howmet after the completion of the separation; and (iii) allocate between Arconic and Howmet various assets, liabilities, and obligations, including, among other things, employee benefits, environmental liabilities, intellectual property, and tax-related assets and liabilities.

Description of the Business
We manage our business operations through three reportable segments: Rolled Products, Building and Construction Systems ("BCS") and Extrusions. We strive to make our portfolio of facilities among the most operationally efficient in the industry. We are well positioned in attractive markets, and our long-term contracts with customers enhance the strength and stability of our business and our earnings. We believe our extensive manufacturing experience and our commitment to quality and innovation have put us in a leadership position among our primary competitors.

(2) In February 2019, we announced an investment of approximately $100 million to expand our hot mill capability and add downstream equipment capabilities to manufacture industrial and automotive aluminum products in our Alcoa, Tennessee facility. This project began in early 2019 and was completed during 2020 and early 2021.
Building and Construction Systems
Our Building and Construction Systems segment manufactures differentiated products and building envelope solutions, including entrances, curtain walls, windows, composite panel and coil coated sheet. The business operates in two markets: architectural systems, which carry the Kawneer® brand, and architectural products, which carry the Reynobond® and Reynolux® brands. The BCS segment has competitive positions in both markets, attributable to its strong brand recognition, high quality products and strong relationships through the building and construction value chain.
As the inventor of the modern storefront more than 100 years ago, our Kawneer® branded architectural systems products include windows, doors and curtain walling. Kawneer is a premium brand, known for the breadth, depth and performance of its product portfolio and is a leading manufacturer of architectural systems in North America, with an established presence in Europe. Key customers of this market segment include fabricators and glazing subcontractors.
The Reynobond and Reynolux brands deliver innovative exterior and interior cladding and coil coated sheet solutions with end uses that include building façades, retail, sign and display, interior applications and various industrial applications. Reynobond is composite material that consists of an extruded core that is fused between two sheets of coil-coated aluminum and Reynolux is coil-coated aluminum sheet that can be sold in coil or flat-sheet form. Key customers include metal fabricators and installers.
BCS differentiates itself through its global footprint and by offering a broad portfolio of building envelope products that span the range of building end-use and building complexities. Architects, general contractors and fabricators consider BCS a go-to provider of products that are offered as systems and are localized to address functional and building code requirements. We believe that our products and systems have a reputation for quality and reliability.
Competitive Conditions
In North America, our BCS segment primarily competes in the nonresidential building segment. In Europe, it competes in both the residential and nonresidential building segments. Our competitive advantage is based on strong brands, innovative products, customer intimacy and technical services.
In the architectural systems market, we compete with regional competitors like Apogee, YKK, and Oldcastle in North America and Schüco, Hydro and Reynaers in Europe. The competitive landscape in the architectural systems market has been relatively stable since the mid-2000s, with the major competitors in North America and Europe remaining constant, despite some industry consolidation in North America during the late 2000s.

Principal facilities are listed and do not include locations that have been idled. In the second half of 2021, the Chandler, AZ facility was fully idled and its commercial operations were integrated into the Lafayette facility. The Company may temporarily restart one or more of the presses at Chandler over short periods of time to address customer demand requirements. See Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Results of Operations—Extrusions—Overview.”
End Market and Customer Revenues
We provide products to customers in a number of end markets, and the revenues from any end market may vary from year to year. For more information regarding revenues by major end markets served, see Note C to the Consolidated Financial Statements in Part II. Item 8. "Financial Statements and Supplementary Data." In addition, the demand for products in certain end markets is concentrated in a relatively small number of customers. We have multi-year contracts with many of our key customers, primarily in the aerospace and ground transportation end markets. These contracts indirectly expose us to changes in these customers' end markets, and the loss of sales under these contracts could have a material adverse effect on our business if such sales are not replaced by sales to other customers.
Customer and Distribution Channels
Rolled Products and Extrusions
Our Rolled Products and Extrusions segments have two primary sales channels: direct sales to our customers and sales to distributors.
Direct Sales
Our Rolled Products and Extrusions segments supply various customers all over the world through a direct sales force operating from individual facilities or sales offices. The direct sales channel typically serves very large, sophisticated customers and OEMs, but can also service medium and small size customers as well. Long-standing relationships are maintained with
10

TABLE OF CONTENTS
leading companies in industries using aluminum rolled and extruded products. Supply contracts for large global customers generally range from one to five years in length and historically there has been a high degree of renewal business with these customers. As the manufacture of higher content aluminum vehicles continues to grow, we continue to develop long-term relationships with the automotive OEMs. In some cases, the products we supply are proprietary in nature. Further, certain industries, such as automotive and aerospace, and their related customers require suppliers to complete a rigorous qualification process. The ability to obtain and maintain these qualifications is an important part of doing business in these segments. A customer’s cost to switch and either find a new product or qualify a new supplier can be significant, so it is in both the customer’s and the supplier’s best interest to maintain these relationships.
Distributors
Our Rolled Products and Extrusions segments also sell their products through third-party distributors. Customers of distributors are typically widely dispersed, and sales through this channel are usually highly fragmented. Distributors sell mostly commodity or less specialized products into many end-use segments in smaller quantities.
Building and Construction Systems
Our Building and Construction Systems segment supplies architectural facade systems and products principally in North America and Europe but also globally through both direct sales and distributors. Its typical customers are installers or fabricators who purchase product on a project-by-project basis. Long-standing relationships are maintained with its leading customers. BCS also maintains an e-commerce platform for numerous standard architectural products for use by its North American customers and offers standard architectural products for purchase in its service centers.
Sources and Availability of Raw Materials
Important raw materials used by Arconic are: primary aluminum for remelting (sows, t-bars, and ingots, including high purity and off-grade), aluminum alloyed and unalloyed casthouse products (including rolling slab and billet), aluminum scrap, alloying materials (including, but not limited to, magnesium, copper, and zinc), aluminum coil, electricity, natural gas, coatings, lube oil, packaging materials, and resin. Generally, other materials are purchased from third-party suppliers under competitively priced supply contracts or bidding arrangements. We believe that the raw materials necessary to the Arconic businesses are and will continue to be available, although we experience and anticipate continued impacts to our supply chain arising from, among other factors, the COVID-19 pandemic and challenges with transportation and logistics.
Intellectual Property
We believe that our domestic and international intellectual property assets provide us with a significant competitive advantage, as we continue to strive to improve our products and processes. Our rights under our patents, as well as the products made and sold under them, are important to us as a whole, and to varying degrees, important to each business segment. The patents owned by us generally concern metal alloys, particular products, manufacturing equipment or techniques. Our business as a whole is not, however, materially dependent on any single patent, trademark or other intellectual property. As a result of product development and technological advancement, we continue to pursue patent protection in jurisdictions throughout the world. As of December 31, 2021, our worldwide patent portfolio consists of approximately 500 granted patents and 250 pending patent applications. Patent terms extend for varying periods based on the filing date or the grant date in the various countries where we have or have applied for patent protection. The actual protection afforded by a patent varies from country to country, with the most significant variations relating to the scope of patent protection and the legal remedies available.
With respect to domestic and foreign trademarks, we have many that have significant recognition within the markets that are served. Examples include the name “Arconic” and the Arconic symbol for aluminum products, Kawneer for building panels, and Reynobond and Reynolux for architectural products. As of December 31, 2021, our worldwide trademark portfolio consists of approximately 1,050 registered trademarks and 50 pending trademark applications. Our rights under our trademarks are important to us as a whole and, to varying degrees, important to each business segment. Trademark protection continues in some countries for as long as the mark is used and in others for as long as it remains registered. Registrations generally are periodically renewable for additional fixed terms.
Research and Development
We engage in research and development programs that include process and product development, and basic and applied research. The Arconic Technology Center (ATC), located in New Kensington, Pennsylvania, serves as the headquarters for our research and development efforts, with additional research and development facilities in Norcross, Georgia; Lancaster, Pennsylvania; Runcorn, United Kingdom; Vendargues, France; and Harderwijk, Netherlands. These facilities focus on

innovation and have given us a leading position in the development of proprietary next-generation specialty alloys, products and manufacturing processes as evidenced by our robust intellectual property portfolio.
Government Regulations
As a global company, our business is subject to government regulations in various jurisdictions in which we operate. We believe we are materially compliant with all applicable government laws and regulations, and maintaining compliance, other than as noted below, is not expected to materially affect our capital expenditures, earnings or competitive position. Any new or amended laws or regulations that impose significant operational restrictions and compliance requirements may negatively impact our business, capital expenditures, earnings, and competitive position. Additional information is included in Part I. Item 1A. "Risk Factors."
Our subsidiaries that own and operate our facility located in Samara, Russia are, and have been since the Separation, subject to proceedings initiated by Russian regulatory authorities as a result of alleged violations of Russian Federal Law No. 57-FZ. In connection with these proceedings, the authorities have imposed injunctions prohibiting, among other actions, the payment of dividends. We cannot at this time reasonably estimate the likelihood or timeline of a resolution involving the removal of these injunctions, and accordingly cannot reasonably estimate when, if at all, the funds will be available for the payment of dividends to Arconic Corporation or the impact of continued or additional restrictions on our business. See Part I. Item 1A. Risk Factors. “Risks Related to Legal Proceedings and Government Regulations”, Part I. Item 2. Properties, Part II. Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Overview—Legal Proceedings Involving our Samara Facility,” and “—Liquidity and Capital Resources” and Note T to the Consolidated Financial Statements in Part II, Item 8. “Financial Statements and Supplementary Data” under the caption “Contingencies and Commitments—Contingencies—Litigation—Federal Antimonopoly Service Of The Russian Federation Litigation” for additional information regarding the proceedings and the potential impact of the proceedings on our business.
Our operations are subject to national, federal, state and local environmental, health and safety laws and regulations, including those regulating the discharge of materials into the environment, greenhouse gas emissions, hazardous materials in products, chemical usage and workplace safety requirements and protocols. We maintain a global environmental, health and safety program that includes appropriate policies and procedures; dedicated environmental, health and safety personnel; appropriate handling of waste materials and hazardous materials; monitoring, reporting and remediating environmental, health, and safety issues; compliance auditing; and training, among other measures.
Approved capital expenditures for new or existing facilities for environmental control are approximately $10 million for 2022. Additional information relating to environmental matters is included in Note T to the Consolidated Financial Statements included in Part II. Item 8. "Financial Statements and Supplementary Data" under the caption “Contingencies and Commitments — Contingencies - Environmental Matters.”
Other than the foregoing, we do not anticipate any material capital expenditures during fiscal 2022 related to compliance with environmental or other government regulations.
Sustainability and Environmental, Social and Governance (ESG)
Arconic is committed to being a good corporate citizen and living our core values by working with our stakeholders to create a better, more sustainable future. In 2021, Arconic partnered with a third party to perform a Materiality Assessment based on GRI Technical Protocol guidance. A critical component of the Materiality Assessment was engaging with a diverse group of key stakeholders, including shareholders, employees, customers, suppliers, and members of the communities in which we operate, to gather and analyze their feedback. We received thoughtful insights on the importance of a wide range of issues, including managing the impacts of our business on the climate and environment, ensuring supply chain sustainability, and fostering human capital. Continuing engagement is critical to enhancing our understanding of stakeholder priorities, shaping our sustainability commitments and guiding our sustainability initiatives in the coming years. Arconic has formed a cross-functional Sustainability and ESG Council tasked with developing our sustainability and ESG strategy, including actionable, measurable targets aligned with United Nations Sustainable Development Goals (UNSDGs), by the end of 2022. The Council regularly reports to senior management and to the Governance and Nominating Committee, which has oversight responsibility for sustainability and ESG matters. All functions responsible for accelerating development and implementation of our sustainability commitments, strategies and initiatives directly report to the CEO. For example, in 2021 we elevated the Environmental, Health and Safety and Sustainability organization to report directly to the CEO to reinforce our sustainability commitment. The use of the terms “material” or “materiality” in our 2021 Sustainability and ESG disclosures is not related to or intended to convey matters or facts that could be deemed “material” to a reasonable investor as referred to under U.S. securities laws or similar requirements of other jurisdictions.

Human Capital Resources
At Arconic, we are committed to living our core values by protecting and improving the health and safety of our employees, our communities and the environment. We cultivate an inclusive and diverse culture that advocates for equity, acts with integrity, and upholds high standards for human rights. We strengthen our global workforce by providing learning opportunities, employee engagement programs and talent development efforts that drive innovation, agility, people development and collaboration.
Our worldwide employment at the end of 2021 was approximately 13,900 employees located in 20 countries. The breakdown of our employees by region is as follows:

Region | Percentage of Total Population
Americas | 57%
Europe, Middle East and Africa | 37%
Asia | 6%

Turnover
In response to the COVID-19 global pandemic, in 2020 the Company initiated significant cost savings efforts, which included a workforce restructuring, temporary salary reductions and a suspension of the Company’s matching contributions to the 401(k). During 2020, the Company’s employee base was reduced by approximately 2,000, largely due to cost-saving initiatives and strategic dispositions, resulting in a distorted employee turnover rate. During 2021, the Company increased hiring initiatives, including encouraging Arconic employee feedback on various workplace-related websites, social media campaigns and targeted events at select locations. As a result of these and other targeted efforts, in 2021 the Company’s employee base increased by approximately 500 employees.
Collective Bargaining Representation
We believe in freedom of association. We respect an individual’s choice to be represented by – or not be represented by – a union or other legally authorized associations or organizations in accordance with the laws of the countries in which we operate. Many of our employees are represented by labor unions. We believe that relations with our employees and any applicable union representatives generally are good. In the United States, approximately 3,700 employees are represented by various labor unions. The largest collective bargaining agreement is the master collective bargaining agreement between us and the United Steelworkers (“USW”). The USW master agreement covers approximately 3,300 employees at four U.S. locations. The current labor agreement expires on May 15, 2022. There are seven other collective bargaining agreements in the United States with varying expiration dates. On a regional basis, there are agreements between Arconic and unions with varying expiration dates that cover employees in Europe, Russia, North America, and Asia.
Governance
The responsibilities of our Compensation and Benefits Committee include the oversight of talent management, which includes (i) talent management strategies, such as the Company’s recruitment, development, promotion and retention programs; (ii) policies and practices promoting diversity and inclusion within the Company; and (iii) key metrics and objectives related to the Company’s talent. Our Board of Directors is also committed to our talent management and has retained direct oversight responsibilities for the Company’s succession plan and our safety practices. During 2021, oversight responsibility for the Company’s ESG policies and strategies was delegated to our Governance and Nominating Committee.

Diversity and Inclusion
We are dedicated to maintaining an environment where everyone feels valued, and we celebrate both the differences and similarities among our people. We also believe that diversity in all areas, including cultural background, experience and thought, is essential in making our Company stronger. The breakdown of our female and ethnic minority employees globally, as members of management and as executives is as follows:

| Total % | Management 3 % | Executive 4 %
Women 1 | 20.4% | 24.0% | 40.0%
Minorities 2 | 21.9% | 13.2% | 30.0%

1 Percentages are on a global basis
2 Percentages are on a U.S. basis only
3 Represents members of management, other than executives
4 Represents our executive leaders who serve in a Vice President or higher role
Our Inclusion Diversity and Equity Council chaired by our Chief Executive Officer continues to advance our mission in partnership with our six employee resource groups (“ERGs”) with executives volunteering as executive sponsors for each group. Our six ERGs – Arconic African Heritage Network, Arconic Hispanic Network, Arconic Next Generation Network, Arconic Veterans Network, Thrive Network (Women) and Spectrum (LGBTQ+) – reflect an inclusive, respectful and values-based company culture. All of our employees are encouraged to participate in these grassroots, employee-led organizations that:
•Drive employee engagement through community outreach ;
•Provide learning and development opportunities for employees;
•Help position Arconic as a global employer of choice through strategic recruiting activities;
•Inform Company policies around diversity and inclusion; and
•Reinforce our brand through key external endorsements like the Human Rights Campaign and Catalyst.
In 2021, we launched our second annual Grow Together Inclusion and Diversity awareness campaign to build on the momentum from the previous year’s introduction of our long-term initiative to support inclusion, diversity and social justice through leadership sponsorship and employee engagement worldwide. The campaign encouraged employees to take actions related to inclusion, diversity or social justice through learning activities, volunteering, and donating to any non-profit organization with a social equity mission that were recommended by our ERGs. At the conclusion of the campaign, Arconic employees had exceeded the original goal, logging more than 4,300 actions, which included approximately 2,600 education actions, 1,180 volunteer hours, and more than $50,000 in personal donations to nonprofits of their choice. As a result, the Arconic Foundation, an independently endowed foundation, granted each of the six selected organizations $50,000, for a total of $300,000.
Talent Development
We are committed to attracting, retaining, and developing talent that shares our values of integrity, inclusion, and diversity, and who demonstrate agility, results focus, and people development capability. All employees have access to a robust, ongoing career planning and performance management process that begins at recruitment and continues throughout their careers. Our twice-yearly succession-planning and calibration processes help us identify successors to business-critical roles while developing our high-potential employees. In addition, we provide management skills training to all supervisory employees, leadership development and coaching programs for mid- and senior-level leaders, and a variety of technical, business, and soft skills training programs to help our business units and resource units meet their strategic objectives.
Compensation and Benefits Programs
Our compensation and benefits programs are designed to provide comprehensive total rewards to attract, motivate, engage and retain a talented workforce. Our programs are competitive with our peers and emphasize performance-based compensation to align employee rewards with company performance. Benefits are a key component of our total rewards package. We offer a holistic benefits package designed to provide greater security for our employees and their families through healthcare, life insurance, paid parental leave, disability, savings and retirement and various welfare benefit programs generally available to all active full-time employees through plans we sponsor or through social programs in the countries where we operate.

Health and Safety
We value human life above all else and are committed to operating worldwide in a safe, responsible manner which respects the environment and the health of our employees, our customers and the communities where we operate. Our strong health and safety culture empowers our employees and contractors to take personal responsibility for their actions and the safety of their coworkers. Our focus on safety also includes an ongoing commitment to maintaining a secure work environment that respects the dignity and worth of every employee, which drives our continuous improvement approach in our robust safety programs. Our employees play an important role in actively supporting a workplace that is free of violence, threats, intimidation, and harassment. This culture is supported by internal policies, standards, rules and procedures that clearly articulate our stringent expectations for working safely and maintaining a secure work environment in all of our facilities worldwide.
In response to the COVID-19 pandemic, we implemented significant changes that we determined were in the best interest of our employees, as well as the communities in which we operate. We established strict requirements for onsite work that is continually assessed against the Centers for Disease Control (“CDC”) and other expert guidance to assure that we are providing a safe work environment.
Sadly, we experienced an employee fatality at our Samara, Russia facility in June 2021. We had zero contractor fatalities in 2021. We are committed to achieving zero fatalities and keeping fatality prevention as a major focus. We conducted fatality assessments for each location in 2021. We have prioritized our risk management processes toward fatality and serious injury potential to focus on the most impactful hazards that have the potential for life-altering outcomes. In addition, during 2021, all of our key safety rates remained significantly below the most recent U.S. industry averages. At 0.42, our 2021 days away, restricted and transfer (“DART”) was 24% lower than our 2020 DART of 0.55. Our 2021 total recordable incident rate (“TRR”) of 0.88 (recorded in accordance with OSHA record keeping requirements) was 7% lower than our 2020 TRR of 0.95.

Item 1A. Risk Factors.
Our 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 our business, financial condition, or results of operations, including causing our actual results to differ materially from those projected in any forward-looking statements. The following list of significant risk factors is not all-inclusive or necessarily in order of importance. Additional risks and uncertainties not presently known to us or that we currently deem immaterial also may materially adversely affect us in future periods
Business Risks – Global Pandemic and Economic Conditions
Our business, results of operations, financial condition, liquidity and cash flows have been, and are expected to continue to be, materially adversely affected by the effects of widespread public health epidemics/pandemics, including COVID-19.
Any outbreaks of contagious diseases, public health epidemics or pandemics or 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, liquidity and/or cash flows. Specifically, the COVID-19 pandemic, including different variants, such as the recent Omicron variant that has caused a significant resurgence of cases, continues to adversely impact our operations. The extent to which COVID-19 affects our operations over time will depend on future developments, which are highly uncertain and beyond our control, including the duration and severity of future variants or outbreaks, the revision of governmental quarantine or other public health measures, the availability of vaccines or other medical remedies and preventive measures, and determinations regarding, among other things, health and safety, demand for specific products, and broader economic conditions. Many of the actions taken to mitigate the impact of the pandemic, including declarations of states of emergency, governmental quarantines, shelter-in-place and stay-at-home orders, social distancing requirements, business closures and staged procedures for reopening, manufacturing restrictions and a prolonged period of travel, commercial and/or other similar restrictions and limitations, have negatively affected our business and the business of many of our customers. The continuation of these restrictions or the imposition of additional restrictions will increase the pandemic’s impact on our businesses and magnify the risks of a material adverse impact on our business, results of operations, financial condition, liquidity and/or cash flows, as well as on our business strategies and initiatives. The status of COVID-19 related restrictions in the areas in which our products are manufactured, distributed or sold may change on short notice in response to new variants or other circumstances. The scope and timing of any such reinstatements is difficult to predict. Because we rely on supply chain continuity, restrictions in one location may materially impact operations in multiple locations, and the impact of COVID-19 in one location may have a disproportionate effect on our operations in the future.

TABLE OF CONTENTS
As a result of COVID-19 and the measures designed to contain its spread, our sales globally, including to customers in the ground transportation, aerospace and building and construction industries that are impacted by COVID-19, have been and may continue to be negatively impacted as a result of disruption in demand, which has had and may continue to have a material adverse effect on our business, results of operations, financial condition, liquidity and cash flows. The COVID-19 pandemic subjects our operations, financial performance and financial condition to a number of risks, including, but not limited to those discussed below. The adverse effects of all of these risks on our business, results of operations, financial condition, liquidity and cash flows will be magnified if the disruption from COVID-19 continues for an extended period.
•Business and operations risks: We continue to monitor the evolving situation relating to COVID-19 to determine whether we need to further 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 business, employees, customers, partners, suppliers and stockholders. While we have since resumed manufacturing operations following temporary idling or production decreases at certain of our facilities during 2020, we could be required to reimpose restrictions or production limitations in response to changes in the pandemic and/or actions by governmental authorities. Furthermore, additional shutdowns, other than those required by governmental authorities, may be necessary to match our production of materials to the reduced demand of our customers. We may also face challenges in restoring and maintaining 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 and/or our customers’ and suppliers’ workforces or continue to disrupt demand and limit the capabilities of our suppliers. Any of these limitations or restrictions could result in our being unable to fully perform, or increase our costs to perform, under production and delivery contracts. A sustained impact to our operations and financial results may require material impairments of our assets including, but not limited to, inventory, goodwill, intangible assets, long-lived assets, right-of-use assets, and deferred income tax assets. In addition, we have incurred and continue to incur certain additional costs as a result of COVID-19, including increased operating costs associated with protective equipment and workforce restructuring actions. Cost-saving measures that we may implement from time to time may not achieve the targeted levels of cost savings or offset the aggregate material adverse effects of the COVID-19 pandemic on our business, results of operations, financial condition, liquidity and/or cash flows to the extent anticipated. In addition, we may determine that it is necessary to modify or rescind cost-saving actions, in which case the planned cost savings would not be fully realized. Further disruptions and uncertainties related to the COVID-19 pandemic and/or the other risks described in this report could require us to take additional cost-saving actions or modify or rescind current cost-saving actions, make additional modifications to our strategic plans and/or incur additional expenses as part of our continued response to COVID-19. Finally, existing and any future requirements, mandates, or business practices in response to the COVID-19 pandemic, including testing, vaccinations, safety protocols and other measures may increase our operating costs and adversely impact our operating cash flows.
•Customer risks: Due to the impacts of COVID-19 on our customers, we are experiencing, and expect to continue experiencing, lower demand and volume for our products, and we have limited visibility into future demand. Several of our customers, including our significant ground transportation and aerospace customers, issued force majeure declarations, temporarily suspended operations or took cost-cutting actions. While many of our customers have resumed operations, many of them remain subject to continued impacts of the COVID-19 pandemic, including labor shortages and supply chain issues, and production has not returned to pre-pandemic levels. It is impossible to predict when our customers will fully resume operations, the status, frequency, or duration of any potential reoccurrences of customer shutdowns, or the duration or extent of resumed operations. We have provided concessions and contract modifications to certain customers, and may do so with additional customers, which may adversely affect our results of operations and cash flows.
•Supply chain risks: We have experienced, and expect to continue to experience, disruptions to our supply chain, which is impacted by, among other factors, labor shortages, increasing costs of raw materials, and challenges with transportation and logistics. Specifically, our suppliers may not have the materials, capacity, or capability to manufacture or supply our materials according to our schedule and specifications due to labor shortages, facility closures, other restrictions related to the COVID-19 pandemic, and similar supply chain challenges with their suppliers. If our suppliers’ operations are 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. These continuing disruptions to our supply chain may adversely impact our business, results of operations, financial condition, liquidity and/or cash flows.
•Market risks: The current financial market dynamics and volatility pose heightened risks to our financial position. For example, dramatically lowered interest rates and lower expected asset valuations and returns can materially impact the
17

TABLE OF CONTENTS
calculation of long-term liabilities such as our pension obligations. In addition, extreme volatility in financial and commodities markets has had and is expected to continue to have adverse impacts on other asset valuations, such as the value of the investment portfolios supporting our pension obligations.
•Liquidity and credit risks: Availability under our asset-based lending credit facility (the "ABL Credit Facility" and the credit agreement forming a part of the ABL Credit Facility, the "ABL Credit Agreement") is based on a borrowing base calculation, and at February 17, 2022 our borrowing base was calculated at approximately $1.1 billion. A prolonged period of generating lower financial results and cash from operations could adversely affect our ability to draw under the ABL Credit Facility, could also adversely affect our financial condition, including in respect of satisfying both required and voluntary pension funding requirements, and could otherwise negatively affect our ability to achieve our strategic objectives. These factors could also adversely affect our ability to maintain compliance with the springing financial maintenance covenant included in the ABL Credit Facility to the extent such covenant becomes applicable, including as a result of potential increases in our net debt or future reductions in our EBITDA. We may face credit rating downgrades as a result of weaker than anticipated performance of our businesses or other factors, including overall market conditions. Future downgrades could further adversely affect our cost of funding and related margins, liquidity, competitive position and access to capital markets, and 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 or our ability to refinance certain of our indebtedness, which could adversely affect our business, results of operations, financial condition, liquidity and/or cash flows. Although the U.S. federal and other governments have implemented a number of funding programs to support businesses, and may announce additional programs in the future, 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.
•Employees and Labor Force: We may face risks associated with the actions we have taken in connection with the outbreak, including those associated with workforce reductions, the safety and welfare of our employees and the reduction of capital expenditures. For example, we are experiencing and may continue to experience difficulties associated with hiring additional employees, or replacing employees following the COVID-19 pandemic, or as we resume production in response to customer demand, in particular with respect to specialized roles. We may face difficulties or incur additional expenses in complying with any applicable local or federal vaccination mandates or similar requirements, and such mandates or requirements may impact our ability to retain current employees or attract new ones. Increased turnover rates of our employees could increase operating costs and create challenges for us in maintaining high levels of employee awareness of and compliance with our internal procedures and regulatory compliance requirements, in addition to increasing our recruiting, training and supervisory costs. In addition, employee health and safety initiatives, such as personal protective equipment, social distancing requirements and other initiatives have resulted and are expected to continue to result in increased expenses.
•End user risk: Our customers’ businesses may be impacted by the financial condition of or other restrictions on the end users of their products or services. In particular, further interruption of regional and international air travel from COVID-19 could have a material adverse effect on our air transportation customers, and the pandemic’s economic impact on individual consumers may continue to have an adverse effect on our automotive customers. Changes in passenger air travel trends and the employment and economic condition of individual consumers arising from COVID-19 are difficult to predict and may continue to develop or persist over time and further contribute to this adverse effect.
The COVID-19 pandemic may also exacerbate other risks disclosed in this Form 10-K, including, but not limited to, risks related to global economic conditions and inflation, competition, loss of customers, costs of supplies, manufacturing difficulties and disruptions, 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 impacts will be on our business, results of operations, financial condition, liquidity 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 condition, liquidity and/or cash flows.
The markets for our products are cyclical and are influenced by a number of factors, including global economic conditions.
We are subject to cyclical fluctuations in global economic conditions and lightweight metals end-use markets. Our many products are sold to industries that are cyclical, such as the aerospace, automotive, commercial transportation and building and construction industries, and the demand for our products are sensitive to, and quickly impacted by, demand for the finished goods manufactured by our 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 our control.
18

TABLE OF CONTENTS
In particular, we derive a significant portion of our revenue from products sold to the aerospace industry, which can be 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. The U.S. and international commercial aviation industries may face challenges arising from competitive pressures and fuel costs. Demand for commercial aircraft 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, environmental constraints imposed upon aircraft operators, the retirement of older aircraft, the performance and cost of alternative materials, and technological improvements to aircraft.
Further, the demand for our ground transportation products is driven by the number of vehicles produced by automotive and commercial transportation manufacturers and volume of aluminum content per vehicle. The automotive industry is 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. Automotive and commercial transportation sales and production can also be affected by other factors, including supply chain disruptions, the age of the vehicle fleet and related scrap rates, labor relations issues, fuel prices, regulatory requirements, government initiatives, trade agreements, interest rates, health and safety concerns and levels of competition both within and outside of the aluminum industry.
Our products are used in a variety of industrial applications, including mold and tooling plate for semiconductors; general engineering/machinery and injection molding applications; specialty finishes for appliances, cosmetic packaging, and vehicle components; tread plate and sheet; and building and construction products. The common alloy sheet market, which is a significant portion of the total industrial products market, is particularly sensitive to the volume imports of common alloys into the United States. The implementation of anti-dumping and countervailing duties imposed on Chinese common alloy sheet during 2018 has led to a significant decrease in the volume of imports from China. However, that decrease was offset by a significant increase in imports of common alloy into the United States from other countries, which led to softening prices and market saturation. Following a subsequent investigation, in 2021 the U.S. government imposed new anti-dumping and countervailing duties on imports of common alloy aluminum sheet from 16 additional countries. The anti-dumping and countervailing duties have led to improved pricing in the US common alloy market, though the long term impact of the tariffs on current import levels and pricing remains difficult to predict.
We are 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 our business, financial condition or results of operations.
We are exposed to economic factors, including inflation, fluctuations in aluminum prices, foreign currency exchange rates and interest rates, and currency controls in the countries in which we operate.
We have experienced, and continue to experience, inflationary pressures on the prices of aluminum, materials, transportation, energy and labor. In an inflationary environment, such as the current economic environment, our ability to implement customer pricing adjustments or surcharges to pass-through or offset the impacts of inflation may be limited. Continued inflationary pressures could reduce our profit margins and profitability.
Other economic factors, including fluctuations in foreign currency exchange rates and interest rates, competitive factors in the countries in which we operate, and continued volatility or deterioration in the global economic and financial environment could affect our revenues, 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 Russian ruble, may affect our profitability as some important inputs are purchased in other currencies, while our products are generally sold in U.S. dollars.
Our ABL Credit Facility bears interest at rates equal to the Secured Overnight Financing Rate (“SOFR”) plus a credit spread adjustment, plus a margin. Accordingly, we will be subject to risk from changes in interest rates on the variable component of the rate.
We also face risks arising from the imposition of cash repatriation restrictions and exchange controls. Cash repatriation restrictions and exchange controls may limit our ability to convert foreign currencies into U.S. dollars or to remit dividends and other payments by our foreign subsidiaries or businesses located in or conducted within a country imposing restrictions or controls. While we currently have no need, and do not intend, to repatriate or convert cash held in countries that have significant restrictions or controls in place, should we need to do so to fund our operations, we may be unable to repatriate or convert such cash, or be unable to do so without incurring substantial costs. We currently have substantial operations in
19

TABLE OF CONTENTS
countries that have cash repatriation restrictions or exchange controls in place, including China, as well as an outstanding injunction preventing our ability to repatriate cash from our Russia operations, and, if we were to need to repatriate or convert such cash, these controls and restrictions may have an adverse effect on our operating results and financial condition.
Our global operations expose us to risks that could adversely affect our business, financial condition, results of operations, cash flows or the market price of our securities, including the potential for increased tensions between the United States and Russia resulting from the current situation involving Russia and Ukraine, tariffs, economic sanctions and import-export restrictions imposed by either nation, and retaliatory actions by the other nation, as well as the potential negative impact on our ability to successfully resolve the current regulatory proceedings involving our Samara facility or our other global operations.
We have operations or activities in numerous countries and regions outside the United States, including Russia, Europe, the United Kingdom, Canada, and China. As a result, our global operations are affected by economic, political and other conditions in the foreign countries in which we do 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 the European Union or other foreign entities), import or export restrictions, taxation, environmental regulations, production curtailments, 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;
•the potential for increased tensions between the United States and countries in which we operate, including China, Russia, and European Union nations;
•deteriorating relations between the United States and Russia resulting from the current situation involving Russia and Ukraine, including tariffs, economic sanctions and import-export restrictions imposed by either nation, and retaliatory actions by the other nation, as well as the potential negative impact on our ability to successfully resolve the current regulatory proceedings involving our Samara facility;
•war or terrorist activities;
•kidnapping of personnel;
•major public health issues such as an outbreak of a pandemic or epidemic (including the COVID-19 pandemic, which has resulted in travel restrictions and shutdown of certain businesses globally, Sudden Acute Respiratory Syndrome, Avian Influenza, H7N9 virus, or the Ebola virus), which could cause disruptions in our operations, workforce, supply chain and/or customer demand;
•shipping, freight and supply chain disruptions;
•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 impact our operations and financial condition and/or 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;
•rising labor costs;
•labor unrest, including strikes;
•compliance with antitrust and competition regulations;
•compliance with foreign labor laws, which generally provide for increased notice, severance and consultation requirements compared to U.S. laws;
•aggressive, selective or lax enforcement of laws and regulations by national governmental authorities;
•compliance with the Foreign Corrupt Practices Act and other anti-bribery and corruption laws;
•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;
•compliance with data privacy regulations; and
•adverse tax laws and audit rulings.
Although the effect of any of the foregoing factors is difficult to predict, any one or more of them could adversely affect our business, financial condition, or results of operations. Our international operations subject us to complex and dynamic laws and regulations that, in some cases, could result in conflict or inconsistency between applicable laws and/or legal obligations. While we believe we have adopted appropriate risk management, compliance programs and insurance arrangements to address
20

TABLE OF CONTENTS
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.
The United Kingdom’s withdrawal from the European Union could adversely affect us.
The United Kingdom’s withdrawal from the European Union (referred to as “Brexit”) became effective on January 31, 2020, and in December 2020 the United Kingdom and the European Union entered into a Trade and Cooperation Agreement to govern certain terms of the withdrawal. The ultimate effects of Brexit on us are difficult to predict, but because we currently operate and conduct business in the United Kingdom and in Europe, Brexit could cause disruptions and create uncertainty to our businesses, including affecting the business of and/or our relationships with our customers and suppliers, as well as altering the relationship among tariffs and currencies, including the value of the British pound and the Euro relative to the U.S. dollar. Such disruptions and uncertainties could adversely affect our financial condition, operating results and cash flows. In addition, Brexit could result in legal uncertainty and potentially divergent national laws and regulations as new legal relationships between the United Kingdom and the European Union are established. The ultimate effects of Brexit on us will also depend on the terms of any agreements the United Kingdom and the European Union make to retain access to each other’s respective markets either during a transitional period or more permanently.
An adverse decline in the liability discount rate, lower-than-expected investment return on pension assets and other factors could affect our results of operations or amount of pension funding contributions in future periods.
We provide defined benefit pension and retiree healthcare benefits to eligible employees and retirees. Our results of operations may be negatively affected by the amount of expense we record for our pension and other postretirement benefit plans, reductions in the fair value of plan assets, significant changes in market interest rates, investment losses or lower than expected returns on plan assets, and other factors. We calculate income or expense for our plans using actuarial valuations in accordance with 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 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, we are required to make an annual measurement of plan assets and liabilities, which may result in a significant charge to stockholders’ equity. For a discussion regarding how our financial statements can be affected by pension and other post-retirement benefits accounting policies, see Note B to the Consolidated Financial Statements in Part II. Item 7. “Management's Discussion and Analysis of Financial Conditions and Results of Operations--Critical Accounting Policies and Estimates.” 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 we would contribute to the pension plans. The defined benefit plans were underfunded as of December 31, 2021 by approximately $693 million based on actuarial methods and assumptions in accordance with GAAP. In the event that actual results differ from the actuarial assumptions, the funded status of our defined benefit plans and future cash contributions may increase or decrease. See Part II. Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations--Contractual Obligations and Off-Balance Sheet Arrangements--Contractual Obligations" and "--Obligations for Operating Activities" for additional information regarding expected contributions and benefit payments in 2022.
Business Risks – Competition and Customers
We face significant competition, which may have an adverse effect on profitability.
The markets for our products are highly competitive. Our competitors include a variety of both U.S. and non-U.S. companies in all major markets. New product offerings, new technologies in the marketplace or new facilities may compete with or replace our products. The willingness of customers to accept substitutes for our products, the ability of large customers to exert leverage in the marketplace to affect the pricing for our products, and technological advancements or other developments by or affecting our competitors or customers could adversely affect our business, financial condition or results of operations. See Part I. Item 1. Business “Description of the Business—Rolled Products—Competitive Conditions,” “Description of the Business—Extrusions—Competitive Conditions,” and “Description of the Business—Building and Construction Systems—Competitive Conditions” for additional information about competition in the markets for our products.
In addition, we 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 our business may acquire or form alliances with our competitors, thereby reducing their
21

TABLE OF CONTENTS
business with us. 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 our 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 our profitability. Moreover, if, as a result of increased leverage, customers require us to reduce our pricing such that our gross margins are diminished, we could decide not to sell certain products to a particular customer, or not to sell certain products at all, which would decrease our revenue. Consolidation within our customer base may also lead to reduced demand for our products, a combined entity replacing our products with those of our competitors, and cancellations of orders. The result of these developments could have a material adverse effect on our business, operating results and financial condition.
We could be adversely affected by the loss of key customers or significant changes in the business or financial condition of our customers.
We have long-term contracts with a significant number of our customers, some of which are subject to renewal, renegotiation or re-pricing at periodic intervals or upon changes in competitive supply conditions. Our 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 could affect our financial results. Our customers may experience delays in the la unch of new products, supply chain disruptions, labor strikes, diminished liquidity or credit unavailability that negatively impact the customer's ability to make full or timely payment or that require us to restructure payment terms, weak demand for their products, or other difficulties in their businesses. For example, in 2019, Boeing announced a temporary reduction in the production rate of, and subsequently announced a temporary suspension of production of, the Boeing 737 MAX aircraft. While the Boeing 737 MAX aircraft has returned to service, Boeing has not resumed production at the same levels as in periods prior to the suspension, which is expected to continue to result in depressed sales of aluminum sheet and plate products that we produce for Boeing airplanes.
Our customers may also change their business strategies or modify their business relationships with us, including to reduce the amount of our products they purchase or to switch to alternative suppliers. If our customers reduce, terminate or delay purchases from us due to the foregoing factors or otherwise and we are unsuccessful in replacing such business in whole or in part or replace it with less profitable business, our financial condition and results of operations may be adversely affected.
Our customers may reduce their demand for aluminum products in favor of alternative materials.
Certain applications of our aluminum-based products compete with products made from other materials, such as steel, titanium, plastics, glass and composites. The willingness of customers to pursue materials other than aluminum often depends upon the desire to achieve specific performance attributes. For example, the commercial aerospace industry has used and continues to evaluate the further use of alternative materials to aluminum, such as titanium and composites, in order to further reduce the weight and increase the fuel efficiency of aircraft. The automotive industry, while motivated to reduce vehicle weight through the use of aluminum, may substitute with steel or other materials for certain applications. The packaging industry continues to experience advances in alternative materials, such as plastics, glass and organic or compostable materials, which may compare favorably to aluminum with respect to preservation of food and beverage quality and recyclability. Further, the decision to use aluminum may be impacted by aluminum prices or compatibility of aluminum with other materials used by a customer in a given application. The willingness of customers to accept other materials in lieu of aluminum could adversely affect the demand for certain of our products, and thus adversely affect our business, financial condition or results of operations.
We may face challenges to our intellectual property rights which could adversely affect our reputation, business and competitive position.
We own important intellectual property, including patents, trademarks and copyrights. Our intellectual property plays an important role in maintaining our competitive position in a number of the markets that we serve. Our competitors may develop technologies that are similar or superior to our proprietary technologies or design around the patents we own or license. Despite our controls and safeguards, our technology may be misappropriated by our employees, our competitors or other third parties. The pursuit of remedies for any misappropriation of our 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 our intellectual property increases despite efforts we undertake to protect it. Developments or assertions by or against us relating to intellectual property rights, and any inability to protect or enforce our rights sufficiently, could adversely affect our business and competitive position.

Business Risks – Operations and Product Development
We could encounter manufacturing difficulties or other issues that impact product performance, quality or safety, which could affect our reputation, business and financial condition and results of operations.
The manufacture of many of our 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, health pandemics (including COVID-19) labor unrest, and environmental factors. Such problems could have an adverse impact on our ability to fulfill orders or on 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 us or our 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.
Our business depends, in part, on our ability to meet increased program demand successfully and to mitigate the impact of program cancellations, reductions and delays.
We are under contract to supply aluminum sheet, plate and extrusions for a number of new and existing commercial and general aviation aircraft programs, as well as aluminum sheet and extrusions for a number of aluminum-intensive automotive vehicle programs. Many of these programs are scheduled for production increases over the next several years. If we fail to meet production levels or encounter difficulty or unexpected costs in meeting such levels, it could have a material adverse effect on our business, financial condition or results of operations. Similarly, program cancellations, reductions or delays could also have a material adverse effect on our business.
A material disruption of our operations, particularly at one or more of our manufacturing facilities, could adversely affect our business.
If our operations, particularly one of our manufacturing facilities, were to be disrupted as a result of significant equipment failures, natural disasters, adverse weather conditions, power outages, fires, floods, explosions, terrorism, theft, sabotage, public health crises, labor disputes or other reasons, we may be unable to effectively meet our obligations to or demand from our customers, which could adversely affect our financial performance.
Our operations depend on the continued and efficient functioning of our facilities, including critical equipment. While we employ a robust maintenance program for our facilities and equipment, we may experience periods of reduced production or production delays due to planned and unplanned equipment outages at our facilities. Our facilities also require significant capital improvements, including upgrades to or replacements of equipment, from time to time. Repairs, equipment replacement or other facility improvement projects may also result in periods of reduced or delayed production. Supply chain issues and labor shortages may impact our ability to obtain parts, materials or replacement equipment necessary to make repairs or improvements, and may increase the time required to complete such repairs or improvements. Unforeseen delays or unavailability of parts or materials could significantly increase the costs associated with repairs or improvements.
Interruptions in production could result in significant increases in our costs and reductions in our sales. Any interruption in production capability could require us 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 our profitability and financial condition. Furthermore, because customers may be dependent on planned deliveries from us, customers that have to reschedule their own production due to our delivery delays may be able to pursue financial claims against us, and we may incur costs to correct such problems in addition to any liability resulting from such claims. While we maintain property damage insurance that we believe to be adequate to provide for reconstruction of facilities and equipment, as well as business interruption insurance to mitigate certain of our losses resulting from significant production interruption or shutdown caused by an insured loss, not all events leading to a disruption of operations are covered events. Additionally, any recovery under our insurance policies may not fully offset the lost profits or increased costs that may be experienced during the disruption of operations, which could adversely affect our business, results of operations, financial condition and cash flow.

TABLE OF CONTENTS
We may be unable to develop innovative new products or implement technology initiatives successfully.
Our competitive position and future performance depend, in part, on our ability to:
•identify and evolve with emerging technological and broader industry trends in our target 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 and services to market quickly and cost-effectively;
•monitor disruptive technologies and understand customers’ and competitors’ abilities to deploy those disruptive technologies; and
•achieve sufficient return on investment for new products based on capital expenditures and research and development spending.
We are working on new developments for a number of strategic projects, including alloy development, engineered finishes and product design, high speed continuous casting and rolling technology and other advanced manufacturing technologies. For more information on our research and development programs, see Part I, Item 1. Business “Research and Development.”
While we intend to continue to commit substantial financial resources and effort to the development of innovative new products and services, we may not be able to successfully differentiate our products or services from those of our competitors or match the level of research and development spending of our competitors, including those developing technology to displace our current products. In addition, we 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 our new products or services, development programs or technologies will be commercially adopted or beneficial to us.
Business Risks – Supply Chain
Our business could be adversely affected by increases in the cost or volatility in the availability of aluminum or other raw materials.
We derive a significant portion of our revenue from aluminum-based products. The price of primary aluminum has historically been subject to significant cyclical price fluctuations, and the timing of changes in the market price of aluminum is largely unpredictable. Although our pricing of products is generally intended to pass substantially all the risk of metal price fluctuations on to our customers or is otherwise hedged, there are situations where we are unable to pass on the entire cost of increases to our customers and there is a potential time lag on certain products between increases in costs for aluminum and the point when we can implement a corresponding increase in price to our customers and/or there are other timing factors that may result in our exposure to certain price fluctuations which could have a material adverse effect on our business, financial condition or results of operations. Further, since metal prices fluctuate among the various exchanges, our competitors may enjoy a metal price advantage from time to time.
We may be adversely affected by changes in the availability or cost of other raw materials (including, but not limited to, copper, magnesium, silicon and zinc), as well as labor costs, energy costs and freight costs associated with transportation of materials. Prices for and the availability of materials necessary for production may fluctuate due to a number of factors, including inflationary pressure, supply shortages and disruptions caused by the COVID-19 pandemic. The availability and costs of certain raw materials necessary for the production of our products may also be influenced by private or government entities, including mergers and acquisitions, changes in world politics or regulatory requirements (such as human rights regulations, environmental regulations or production curtailments), labor relations between the producers and their work forces, labor shortages, unstable governments in exporting nations, export quotas, sanctions, new or increased import duties, countervailing or anti-dumping duties, infrastructure and transportation issues, 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. We may be unable to offset fully the effects of 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 our operating results.
We are dependent on a limited number of suppliers for a substantial portion of our primary and scrap aluminum and certain other raw materials essential to our operations.
We have supply arrangements with a limited number of suppliers for aluminum and other 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. From time to time, increasing aluminum 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

TABLE OF CONTENTS
primary metal and other supplies from alternative sources, which may not be available in sufficient quantities or may only be available on terms that are less favorable to us. Further, 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. Additionally, we could have exposure if a key supplier in a particular region is unable to deliver sufficient quantities of a necessary material on a timely basis. For example, our plant in Russia depends on a single supplier, UC Rusal PLC, for aluminum. A significant interruption in that supply could jeopardize the plant’s ability to continue as a going concern, which could in turn have a material adverse effect on our financial condition, results of operations and cash flow. In addition, a significant downturn in the business or financial condition of our significant suppliers exposes us to the risk of default by the supplier on our contractual agreements, and this risk is increased by weak and deteriorating economic conditions on a global, regional or industry sector level.
We also depend on scrap aluminum for our operations and acquire our scrap inventory from numerous sources. These suppliers generally are not bound by long-term contracts and have no obligation to sell scrap metal to us. In periods of low inventory prices, suppliers may elect to hold scrap until they are able to charge higher prices. Additionally, the purity and attributes of scrap material can vary significantly, which could result in a shortage of useable scrap metal. If an adequate supply of scrap metal is not available to us, we would be unable to recycle metals at desired volumes and our results of operation, financial condition and cash flows could be materially adversely affected.
Business Risks – Strategy
We may not be able to successfully implement our strategic decision to re-enter the packaging market in the U.S. and other geographies.
We have made a strategic decision to re-enter the packaging market in the U.S. and other geographies. Our re-entry into these markets involves investment of management time and financial resources, including capital investments in machinery, application of research and development resources to developing innovations in packaging materials, re-tooling portions of our rolled products capacity to produce materials designed to suit the needs of customers in the packaging market, supplementing our workforce to fulfill capacity, and engaging with a new customer base that has different needs than our aerospace, automotive, and industrial customers. In addition, the competitive landscape in the packaging market involves not only some of our current key competitors, but also new competitors offering alternative packaging materials, particularly plastics and glass products, many of whom are larger and more established in the packaging market than we are. If we are unsuccessful in implementing our re-entry into the packaging market in the U.S. or other geographies, or if we experience significant delays or unexpected costs in doing so, our financial condition and results of operations may be materially adversely affected.
We may be unable to realize future targets or goals established for our business segments, or complete projects at the levels, projected costs or by the dates targeted.
From time to time, we may announce future targets or goals for our business, which are based on our then current expectations, estimates, forecasts and projections about the operating environment, economies and markets in which we operate. Future targets and goals reflect our beliefs and assumptions and our perception of historical trends, then current conditions and expected future developments, as well as other factors appropriate in the circumstances. As such, targets and goals are inherently subject to significant business, economic, competitive and other uncertainties and contingencies regarding future events, including the risks discussed therein. The actual outcome may be materially different. There can be no assurance that any targets or goals established by us will be accomplished at the levels or by the dates targeted, if at all. Failure to achieve our targets or goals may have a material adverse effect on our business, financial condition, results of operations or the market price of our securities.
In addition, the implementation of our business strategy may involve the entry into and the execution of complex projects, which place significant demands on our management and personnel, and may depend on numerous factors beyond our 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 herein, or other factors. The failure to complete a material project as planned, or a significant delay in a material project, whatever the cause, could have an adverse effect on our business, financial condition, or results of operations.
Our business and growth prospects may be negatively impacted by limits in our capital expenditures.
We require substantial capital to invest in growth opportunities and to maintain and prolong the life and capacity of our existing facilities. Insufficient cash generation or capital project overruns may negatively impact our ability to fund as planned our sustaining and return-seeking capital projects. Over the long term, our ability to take advantage of improved market
25

TABLE OF CONTENTS
conditions or growth opportunities in our businesses may be constrained by earlier capital expenditure restrictions, which could adversely affect the long-term value of our business and our position in relation to our competitors.
We may be unable to realize the expected benefits from acquisitions, divestitures, joint ventures and strategic alliances.
We have made, and may continue to plan and execute, acquisitions and divestitures and take other actions to grow our business or streamline our portfolio. There is no assurance that anticipated benefits will be realized. Acquisitions present significant challenges and risks, including our effective integration of the acquired business, unanticipated costs and 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. We may be unable to manage acquisitions successfully. Additionally, adverse factors may prevent us from realizing the benefits of our 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, we 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, we may retain unforeseen liabilities for divested entities or businesses, including, but not limited to, if a buyer fails to honor all commitments. Our 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, we have participated in, and may continue to participate in, joint ventures, strategic alliances and other similar arrangements from time to time. Although we have, in connection with past and existing joint ventures, sought to protect our interests, joint ventures and strategic alliances inherently involve special risks. Whether or not we hold majority interests or maintains operational control in such arrangements, our partners may:
•have economic or business interests or goals that are inconsistent with or opposed to ours;
•exercise veto rights to block actions that we believe to be in our or the joint venture’s or strategic alliance’s best interests;
•take action contrary to our policies or objectives with respect to investments; or
•as a result of financial or other difficulties, be unable or unwilling to fulfill their obligations under the joint venture, strategic alliance or other agreements, such as contributing capital to expansion or maintenance projects.
There can be no assurance that acquisitions, growth investments, divestitures, closures, joint ventures, strategic alliances or similar arrangements will be undertaken or completed in their entirety as planned or that they will be beneficial to us, whether due to the above-described risks, unfavorable global economic conditions, increases in construction costs, currency fluctuations, political risks, or other factors.
A decline in our financial performance or outlook or a deterioration in our credit profile could negatively impact our access to the capital markets and commercial credit, reduce our liquidity, and increase our borrowing costs.
We have significant capital requirements and may require, in the future, the issuance of debt to fund our operations and contractual commitments or to pursue strategic acquisitions. A decline in our financial performance or outlook due to internal or external factors could affect our access to, and the availability or cost of, financing on acceptable terms and conditions. There can be no assurance that we will have access to the capital markets on terms we find acceptable.
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 and execution. 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 we receive will impact our borrowing costs as well as the terms upon which we will have access to capital. Failure to obtain 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.
There can be no assurance that one or more of the rating agencies will not take negative actions with respect to our ratings in the future. Increased debt levels, macroeconomic conditions, a deterioration in our debt protection metrics, a contraction in our 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 our credit ratings by one or more rating agencies could result in adverse consequences, including: adversely impact the market price of our securities; adversely affect existing financing; limit access to the capital (including commercial paper) or credit
26

TABLE OF CONTENTS
markets or otherwise adversely affect the availability of other new financing on favorable terms, if at all; result in more restrictive covenants in agreements governing the terms of any future indebtedness that we incur; increase the cost of borrowing or fees on undrawn credit facilities; or result in vendors or counterparties seeking collateral or letters of credit from us.
Limitations on our ability to access the global capital markets, a reduction in our liquidity or an increase in borrowing costs could materially and adversely affect our ability to maintain or grow our business, which in turn may adversely affect our financial condition, liquidity and results of operations.
Business Risks – Information Security and Internal Controls
Information technology system failures, cyber-attacks and security breaches may threaten the integrity of our intellectual property and sensitive information, disrupt our business operations, and result in reputational harm and other negative consequences that could have a material adverse effect on our financial condition and results of operations.
We rely on our information technology systems to manage and operate our business, process transactions, and summarize our operating results. Our information technology systems are subject to damage or interruption from power outages, computer, network and telecommunications failures, computer viruses, and catastrophic events, such as fires, floods, earthquakes, tornadoes, hurricanes, acts of war or terrorism, and usage errors by employees. If our information technology systems are damaged or cease to function properly, we may have to make a significant investment to fix or replace them, and we may suffer loss of critical data and interruptions or delays in our operations. Any material disruption in our information technology systems, or delays or difficulties in implementing or integrating new systems or enhancing current systems, could have an adverse effect on our business, financial condition or results of operations.
We believe that we face the threat of cyber-attacks due to the industries we serve, the locations of our operations and our technological innovations. These cyber-attacks may range from uncoordinated individual attempts to sophisticated and targeted measures, known as advanced persistent threats, directed at us and our customers, suppliers and vendors. 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, any of which could manipulate or improperly use our systems or networks, compromise confidential information, destroy or corrupt data, or otherwise disrupt our operations. We have experienced cybersecurity attacks in the past, including breaches of our 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 our 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.
We continually work to safeguard our systems and mitigate potential risks, and our enterprise risk management program and disclosure controls and procedures include elements intended to ensure that we analyze potential disclosure obligations arising from cyber-attacks and security breaches. However, there is no assurance that these safeguards and controls will be sufficient to detect, prevent, engage in timely response to, or report cyber-attacks or security breaches. The occurrence of cyber-attacks or security breaches could negatively impact our reputation and competitive position and could result in litigation with third parties, regulatory action, loss of business, diminution of the value of investments in research and development, potential liability and increased remediation costs, any of which could have a material adverse effect on our financial condition and results of operations.
If we fail to maintain an effective system of internal controls, we may not be able to accurately report financial results or prevent fraud.
We are subject to reporting and other obligations under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), the Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act, and the regulations of the NYSE, and to the requirements of Section 404 of Sarbanes-Oxley which requires management to establish and maintain internal control over financial reporting and disclosure controls and procedures. 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 in accordance with generally accepted accounting principles. Internal controls are also important in the prevention and detection of fraudulent activity. Disclosure controls and procedures are processes designed to ensure that information required to be disclosed is communicated to management and reported in a timely fashion. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance with respect to the reliability of reporting, including financial reporting and financial statement preparation. If we are not able to maintain effective internal control over financial reporting or disclosure controls and procedures, or other accounting, financial management or reporting systems or procedures, or experience difficulties or delays in the implementation of systems or controls, we may not be able to accurately report our financial results or prevent fraud, and in some cases may be required to restate financial results. As a result,
27

TABLE OF CONTENTS
stockholders could lose confidence in our financial and other public reporting, could result in adverse regulatory consequences and/or loss of investor confidence, which could limit our ability to access the global capital markets and could have a material adverse effect on our business, financial condition, results of operations, cash flows or the market price of our securities. In addition, the remediation of any ineffective internal controls could result in unforeseen expenses.
Risks Related to Employee and Labor Matters
Labor disputes and difficulties retaining or hiring trained employees could adversely affect our business, financial condition or results of operations.
The continuity of our operations depends on maintaining a trained workforce. We have experienced and continue to experience shortages of qualified labor. Conditions caused by the COVID-19 pandemic, such as illness, concerns over safety and increased health and safety requirements, and actions taken by us in response to the COVID-19 pandemic, such as furloughs, could result in difficulty retaining or hiring workers. While the labor shortages are due in part to the COVID-19 pandemic, other economic factors have contributed to the current labor shortage, and may continue to exacerbate labor shortages in the future. Any continuing shortage could decrease our ability to effectively produce and deliver product and to achieve our strategic objectives. In addition, a continued labor shortage may result in increased expenses related to hiring and retention of qualified employees.
Furthermore, a significant portion of our employees are represented by labor unions in a number of countries under various collective bargaining agreements with varying durations and expiration dates. While we previously have been successful in renegotiating our collective bargaining agreements with various unions, we 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 our facilities in the future. We may also be subject to general country strikes or work stoppages unrelated to our business or collective bargaining agreements. Any such work stoppages could have a material adverse effect on our business, financial condition or results of operations.
A failure to attract, retain or provide adequate succession plans for key personnel could adversely affect our operations and competitiveness.
Our existing operations and development projects require highly skilled executives and staff with relevant industry and technical experience. Our inability to attract and retain such people may adversely impact our ability to meet project demands adequately and fill roles in existing operations. Skills shortages in engineering, manufacturing, technology, construction and maintenance contractors and other labor market inadequacies may also impact activities. These shortages may adversely impact the cost and schedule of development projects and the cost and efficiency of existing operations.
In addition, the continuity of key personnel and the preservation of institutional knowledge are vital to the success of our growth and business strategy. The loss of key members of management and other personnel could significantly harm our business, and any unplanned turnover, or failure to develop adequate succession plans for key positions, could deplete our institutional knowledge base, result in loss of technical expertise, delay or impede the execution of our business plans and erode our competitiveness.
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 our business results.
We are 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 we have violated such laws or regulations could damage our 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 our operations and financial condition.

Risks Related to Legal Proceedings and Government Regulations
Our Samara, Russia facility is subject to restrictions imposed by regulatory authorities, which may impact our financial condition, results of operations or cash flows.
Our subsidiaries that own and operate our facility located in Samara, Russia are, and have been since the Separation, subject to proceedings initiated by Russian regulatory authorities as a result of alleged violations of Russian Federal Law No. 57-FZ. In connection with these proceedings, authorities have imposed injunctions prohibiting, among other actions, the payment of dividends, placement of bonds, amendments to organizational documents, and changes to the subsidiaries’ chief executive officer and board of directors, which may materially impact our financial condition, results of operations or cash flows. The proceedings and underlying claims may not be resolved favorably, are likely to continue to be delayed, may be resolved in a manner that results in permanent injunctions similar to or more restrictive than the current injunctions, and could result in a decision or a requirement to divest some or all of the assets located at the Samara facility. We cannot at this time reasonably estimate the likelihood or timing of any resolutions of the regulatory proceedings or underlying claims, whether such resolution would include the removal of the injunctions or the imposition of additional restrictions, or whether we would divest assets related to the Samara facility. Approximately $79 million, or 24%, of Arconic’s Cash and cash equivalents at December 31, 2021 is currently held in Russia and is not available for dividends. Cash and cash equivalents held in Russia represented 7% of Arconic’s liquidity (comprised of Cash and cash equivalents of $335 million and undrawn availability of $790 million under Arconic’s ABL Credit Agreement) at December 31, 2021. In addition, approximately $968 million, or 16% of third-party sales (including packaging, industrial, aerospace and defense), and approximately $87, or 13% of Segment Adjusted EBITDA, for the Rolled Products segment for the year ended December 31, 2021 were generated by our Samara, Russia facility. Additional restrictions on our operation of the Samara facility could result in continued unavailability of funds for the payment of dividends to Arconic Corporation. A divestiture could result in decreases in or loss of third-party sales and Segment Adjusted EBITDA generated by our Samara facility, restrictions on capital investments in our Samara facility, loss on sale, an inability to apply capacity at other locations to offset decreases in sales or Segment Adjusted EBITDA or assume divested capacity, and increased costs related to the relocation of capacity, and could have an indirect impact on the performance of our other locations. Any of these occurrences would have a material adverse effect on our financial condition, results of operations or cash flows. In addition, any impact on our ability to fulfill delivery obligations could subject us to reputational harm and potential litigation involving customers and suppliers. See Part II. Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Overview—Legal Proceedings Involving our Samara Facility,” and “—Liquidity and Capital Resources” and Note T to the Consolidated Financial Statements in Part II. Item 8. “Financial Statements and Supplementary Data” under the caption “Contingencies and Commitments—Contingencies—Litigation—Federal Antimonopoly Service Of The Russian Federation Litigation” for additional information for additional information regarding the proceedings and the potential impact of the proceedings on our business.
Product liability, product safety, personal injury, property damage, and recall claims and investigations may materially affect our financial condition and damage our reputation.
The manufacture and sale of our products exposes us to potential product liability, personal injury, property damage and related claims. These claims may arise from our alleged failure to meet product specifications, design flaws in our products, malfunction of our products, 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 our products are used, may lead regulatory authorities, government agencies or other entities or organizations to publish guidelines or recommendations, or impose restrictions, related to the manufacturing or use of our products.
In the event that a product of ours 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, we may be subject to product liability lawsuits and other claims, or may be required or requested by our customers to participate in a recall or other corrective action involving such product. In addition, if a product of ours is perceived to be defective or unsafe, sales of our products could be diminished, our reputation could be adversely impacted, and we could be subject to further liability claims. Moreover, events that give rise to actual, potential or perceived product safety concerns could expose us to government investigations or regulatory enforcement action.
There can be no assurance that we will be successful in defending any such proceedings or that insurance available to us will be sufficient to cover any losses associated with such proceedings. An adverse outcome in one or more of these proceedings or investigations could have a material adverse effect on our business, financial condition or profitability; impose substantial monetary damages and/or non-monetary penalties; result in additional litigation, regulatory investigations or other proceedings involving us; result in loss of customers; require changes to our products or business operations; damage our
29

TABLE OF CONTENTS
reputation and/or negatively impact the market price of our common stock. Even if we successfully defend against these types of claims, we could still be required to spend a substantial amount of money in connection with legal proceedings or investigations with respect to such claims; our 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 our 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 our business, financial condition and reputation and on our ability to attract and retain customers.
For further discussion of potential liability associated with some of our products, including proceedings and investigations relating to the June 13, 2017 fire at the Grenfell Tower in London, U.K., see No te T to the Consolidated Financial Statements in Part II. Item 8. "Financial Statements and Supplementary Data" under the caption "Contingencies and Commitments - Contingencies."
We may be exposed to significant legal proceedings, investigations or changes in U.S. federal, state or foreign law, regulation or policy.
Our 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 us. We 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.
We are subject to a variety of legal and regulatory compliance risks in the United States and abroad in connection with our 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 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. We may be a party to litigation in a foreign jurisdiction where geopolitical risks might influence the ultimate outcome of such litigation. We 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 our operations means that these risks will continue to exist, and additional legal proceedings and contingencies may arise from time to time. While we believe we have 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 us to change current estimates of liabilities or make such estimates for matters previously insusceptible 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 we cannot predict with certainty could have a material adverse effect on our 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 our financial position, results of operations and cash flows. For additional information regarding our legal proceedings, including proceedings and investigations relating to the June 13, 2017 fire at the Grenfell Tower in London, U.K., see Note T to the Consolidated Financial Statements in Part II, Item 8. "Financial Statements and Supplementary Data" under the Caption "Contingencies and Commitments - Contingencies."
We are exposed to environmental and safety risks and are subject to a broad range of health, safety and environmental laws and regulations, which may result in substantial costs and liabilities.
Our 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. Failure to comply with such laws and regulations could result in significant penalties or criminal liability. 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 caused the contamination was lawful at the time it was conducted. Environmental matters for which we may be liable may arise in the future at our present sites, at sites owned or operated by our predecessors or affiliates, at sites that we may acquire in the future, or at third-party sites used by our 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
30

TABLE OF CONTENTS
we anticipate. Our 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 our 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 our financial condition, results of operations and cash flows.
In addition, the heavy industrial activities conducted at our 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. While we maintain insurance and have in place policies to minimize such risks, we may nevertheless be unable to avoid material liabilities for any injury or death that may occur in the future. 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.
We are subject to privacy and data security/protection laws in the jurisdictions in which we operate 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 as well as significant fines for non-compliance. For example, China recently implemented a new Personal Information Protection Law (“PIPL”) for the protection of personal information of individuals in China. While Arconic has processes and procedures in place to comply with existing data protection regulations in other countries, such as the European Union’s General Data Protection Regulation (“GDPR”), further changes may be necessary to ensure those processes and procedures will be adequate to implement PIPL. 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 our financial condition and results of operations. In addition, the payment of potentially significant fines or penalties in the event of a breach of privacy and information security laws, as well as the negative publicity associated with such a breach, could damage our reputation and adversely impact product demand and customer relationships.
We 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, limits on emissions of greenhouse gases or Corporate Average Fuel Economy standards in the United States, and similar standards or requirements in the European Union or in other jurisdictions. For example, in January 2021 the United States recommitted to the Paris Agreement and in April 2021, President Biden announced targets to reduce U.S. greenhouse gas emissions. New or revised laws and regulations in this area could directly and indirectly affect us and our 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 us or our customers or suppliers, including increased monitoring and reporting costs. Also, we rely on natural gas, electricity, fuel oil and transport fuel to operate our facilities. Any increased costs of these energy sources because of new laws or regulations could be passed along to us and our customers and suppliers, which could also have a negative impact on our profitability. Any increased frequency and intensity of extreme weather events resulting from climate change impacting our facilities, our suppliers or critical infrastructure in the United States and abroad could disrupt our supply chain or impact our ability to timely produce and deliver our products.
Unanticipated changes in our tax provisions or exposure to additional tax liabilities could affect our future profitability.
We are subject to income taxes in both the United States and various non-U.S. jurisdictions. Our 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 our tax expense and profitability. Our 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 our future earnings that could impact the valuation of our deferred tax assets. Our 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 our overall profitability, 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

TABLE OF CONTENTS
filed tax returns or related litigation and continuing assessments of our tax exposures. Any failure to comply with all such tax laws or regulations could subject us to liability.
Corporate tax law changes continue to be analyzed in the United States and in many other jurisdictions. The Organisation for Economic Co-operation and Development and current United States presidential administration have proposed changes that could adversely impact the taxation of corporations in the U.S. and abroad. Any change to the U.S. corporate tax system could have a substantial impact, positive or negative, on our future effective tax rate, cash tax expenditures, and deferred tax assets and liabilities.
Risks Related to Our Indebtedness
We have significant debt obligations, and may in the future incur, additional debt obligations that could adversely affect our business and profitability and our ability to meet other obligations.
On February 7, 2020, we completed an offering for $600 million of 6.125% (fixed rate) Senior Secured Second-Lien Notes due 2028 (the “2028 Notes”). On May 13, 2020, we completed an offering of $700 million principal amount of 6.0% Senior Secured First-Lien Notes due 2025 (the "2025 Notes"). Also on May 13, 2020, we entered into the ABL Credit Agreement, which provides for a senior secured asset-based revolving credit facility in an aggregate principal amount of $800 million, including a letter of credit sub-facility, a swingline loan sub-facility and an accordion feature allowing the Company to request one or more increases to the revolving commitments in an aggregate principal amount up to $350 million. We increased the aggregate principal amount of the ABL Credit Agreement in February 2022 to $1.2 billion. We may also incur additional indebtedness in the future, including by drawing under the ABL Credit Facility.
This significant amount of debt could potentially have important consequences to us and our debt and equity investors, including:
•requiring a substantial portion of our cash flow from operations to make interest payments;
•making it more difficult to satisfy debt service and other obligations;
•increasing the risk of a future credit ratings downgrade of our debt, which could increase future debt costs and limit the future availability of debt financing;
•increasing our vulnerability to general adverse economic and industry conditions;
•reducing the cash flow available to fund capital expenditures and other corporate purposes and to grow our business;
•limiting our flexibility in planning for, or reacting to, changes in our business and the industry;
•placing us at a competitive disadvantage relative to our competitors that may not be as highly leveraged with debt; and
•limiting our ability to borrow additional funds as needed or take advantage of business opportunities as they arise, pay cash dividends or repurchase securities.
Subject to the restrictions in the indenture governing the 2025 Notes, the indenture governing the 2028 Notes and the ABL Credit Agreement, we, including our subsidiaries, have the ability to incur significant additional indebtedness. Although the terms of the 2025 Notes indenture, the 2028 Notes indenture and the ABL Credit Facility include restrictions on the incurrence of additional indebtedness, these restrictions are subject to a number of important exceptions, and indebtedness incurred in compliance with these restrictions could be substantial. Adding new debt to our current debt levels could intensify the related risks that we and our subsidiaries face now or may face in the future. In addition, our actual cash requirements in the future may be greater than expected. Our cash flow from operations may not be sufficient to repay all of the outstanding debt as it becomes due, and we may not be able to borrow money, sell assets or otherwise raise funds on acceptable terms, or at all, to refinance our debt
Our indebtedness restricts our current and future operations, which could adversely affect our ability to respond to changes in our business and manage our operations.
The terms of the 2025 Notes indenture, the 2028 Notes indenture and the ABL Credit Agreement include a number of restrictive covenants that impose significant operating and financial restrictions on us, including restrictions on our ability to, among other things:
•make investments, loans, advances, guarantees and acquisitions;
•dispose of assets;
•incur or guarantee additional debt and issue certain disqualified equity interests and preferred stock;
•make certain restricted payments, including a limit on dividends on equity securities or payments to redeem, repurchase or retire equity securities or other indebtedness;
•engage in transactions with affiliates;
32

TABLE OF CONTENTS
•enter into certain restrictive agreements;
•create liens on assets to secure debt; and
•consolidate, merge, sell or otherwise dispose of all or substantially all of our or a subsidiary guarantor’s assets.
These covenants limit our operational flexibility and could prevent us from taking advantage of business opportunities as they arise, growing our business or competing effectively. In addition, the ABL Credit Facility contains a financial maintenance covenant applicable when the excess availability is less than the greater of (a) 10% of the lesser of (x) the aggregate amount of the commitments under the ABL Credit Facility and (y) the borrowing base and (b) $50.0 million. In such circumstances, we would be required to maintain a fixed charge coverage ratio of not less than 1.00 to 1.00. Our ability to draw under the ABL Credit Facility could be impacted by a number of factors, including but not limited to any impact by disruptions to our operations and financial performance.
The ABL Credit Facility also provides for “springing control” over the cash in our deposit accounts constituting ABL priority collateral for the ABL Credit Facility, and such cash management arrangement includes a cash sweep at any time that excess availability under the ABL Credit Facility is less than the greater of (x) 12.5% of the lesser of the borrowing base and the aggregate amount of the commitments under the ABL Credit Facility at such time and (y) $62.5 million for five consecutive business days. Such cash sweep, if in effect, will cause all our available cash in deposit accounts subject to such “springing control” to be applied to outstanding borrowings under our ABL Credit Facility. If we satisfy the conditions to borrowings under the ABL Credit Facility while any such cash sweep is in effect, we may be able to make additional borrowings under the ABL Credit Facility to satisfy our working capital and other operational needs. If we do not satisfy the conditions to borrowing, we will not be permitted to make additional borrowings under our ABL Credit Facility, and we may not have sufficient cash to satisfy our working capital and other operational needs.
Our ability to comply with these agreements may be affected by events beyond our control, including prevailing economic, financial and industry conditions. These covenants could have an adverse effect on our business by limiting our ability to take advantage of financing, merger and acquisition or other opportunities. The breach of any of these covenants or restrictions could result in a default under the 2025 Notes indenture, the 2028 Notes indenture or the ABL Credit Agreement.
Our failure to comply with the agreements relating to our outstanding indebtedness, including as a result of events beyond our control, could result in an event of default that could materially and adversely affect our business, financial condition, results of operations or cash flows.
If there were an event of default under any of the agreements relating to our outstanding indebtedness, including the 2025 Notes indenture, the 2028 Notes indenture and the ABL Credit Agreement, we may not be able to incur additional indebtedness and the holders of the defaulted indebtedness could cause all amounts outstanding with respect to that indebtedness to be immediately due and payable. We cannot assure you that our assets or cash flow would be sufficient to fully repay our outstanding indebtedness if accelerated upon an event of default, which could have a material adverse effect on our ability to continue to operate as a going concern. Further, if we are unable to repay, refinance or restructure our secured indebtedness, the holders of such indebtedness could proceed against the collateral securing that indebtedness. In addition, any event of default under or declaration of acceleration under one debt instrument also could result in an event of default under one or more of the agreements governing our other indebtedness.
Risks Related to the Separation
We have a limited history of operating as an independent company, and our historical financial information is not necessarily representative of the results that we will achieve as a separate, publicly traded company and may not be a reliable indicator of our future results.
The historical information included in this Annual Report on Form 10-K for periods prior to the separation refers to the Arconic as operated by and integrated with ParentCo for those periods. Our historical financial information is derived from ParentCo’s accounting records and is presented on a standalone basis as if Arconic was independent of ParentCo. Accordingly, the historical information does not necessarily reflect the financial condition, results of operations or cash flows that we would have achieved as a separate, publicly traded company during the periods presented or those that we will achieve in the future primarily as a result of the factors described below:
•Prior to the separation, our working capital requirements and capital for our general corporate purposes, including capital expenditures and acquisitions, were satisfied as part of the corporate-wide cash management policies of ParentCo. Our results of operations and cash flows may be more volatile as a separate, publicly traded company, and we may need to obtain additional financing from banks, through public offerings or private placements of debt or
33

TABLE OF CONTENTS
equity securities, strategic relationships or other arrangements, which may or may not be available and may be more costly.
•Prior to the separation, our business was operated by ParentCo as part of its broader corporate organization, rather than as an independent company. ParentCo or one of its affiliates performed various corporate functions for us, such as legal, treasury, accounting, auditing, human resources, investor relations, and finance. Our historical financial results reflect allocations of corporate expenses from ParentCo for such functions, which may be less than the expenses we incur operating as a separate, publicly traded company.
•Historically, we have shared economies of scope and scale in costs, employees, vendor relationships and customer relationships. While we have sought to minimize the impact on us when separating these arrangements, there is no guarantee these arrangements will continue to capture these benefits in the future.
•Prior to the separation, we took advantage of ParentCo’s overall size and scope to obtain more advantageous procurement terms. As a standalone company, we may be unable to obtain similar arrangements to the same extent as ParentCo did, or on terms as favorable as those ParentCo obtained, prior to completion of the separation.
•The cost of capital for our business may be higher than ParentCo’s cost of capital prior to the separation.
•Our historical financial information does not reflect the debt that we incurred as part of the separation.
Other significant changes have occurred and may occur in our cost structure, management, financing and business operations as a result of operating as a company separate from ParentCo. For additional information about the past financial performance of our business, see Part II, Item 6. “Selected Financial Data,” Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and Part II, Item 8. “Financial Statements and Supplementary Data.”
We may not achieve some or all of the expected benefits of the separation.
We may not be able to achieve the full strategic and financial benefits expected to result from the separation, or such benefits may be delayed or not occur at all. The separation is expected to provide the following benefits, among others: (1) enabling our management to more effectively pursue our own distinct operating priorities and strategies and to focus on strengthening our core business and unique needs, and pursue distinct and targeted opportunities for long-term growth and profitability; (2) permitting us to allocate our financial resources to meet the unique needs of our business, which will allow us to intensify our focus on distinct strategic priorities and to more effectively pursue our own distinct capital structures and capital allocation strategies; (3) allowing us to more effectively articulate a clear investment thesis to attract a long-term investor base suited to our business and providing investors with a distinct and targeted investment opportunity; (4) creating an independent equity security tracking our underlying business, affording us direct access to the capital markets and facilitating our ability to consummate future acquisitions or other transactions using our common stock; and (5) permitting us to more effectively recruit, retain and motivate employees through the use of stock-based compensation that more closely aligns management and employee incentives with specific business goals and objectives related to our business.
We may not achieve these and other anticipated benefits for a variety of reasons, including, among others: (1) we now may be more susceptible to market fluctuations and other adverse events than if we were still a part of ParentCo because our business is less diversified than ParentCo’s business prior to the completion of the separation; (2) as a standalone company, we may be unable to obtain certain goods, services and technologies at prices or on terms as favorable as those ParentCo obtained prior to completion of the separation; (3) the separation required and may continue to require us to pay costs that could be substantial and material to our financial resources, including accounting, tax, legal and other professional services costs, recruiting and relocation costs associated with hiring new key senior management and personnel, tax costs and costs to separate information systems; and (4) under the terms of the tax matters agreement that we entered into with ParentCo, we are restricted from taking certain actions that could cause the distribution or certain related transactions to fail to qualify as tax-free and these restrictions may limit us for a period of time from pursuing certain strategic transactions and equity issuances or engaging in other transactions that might increase the value of our business. If we fail to achieve some or all of the benefits expected to result from the separation, or if such benefits are delayed, it could have a material adverse effect on our competitive position, business, financial condition, results of operations and cash flow.
In connection with the separation into two public companies, we and Howmet have agreed to indemnify each other for certain liabilities. If we are required to pay under these indemnities to Howmet, our financial results could be negatively impacted. The Howmet indemnities may not be sufficient to hold us harmless from the full amount of liabilities for which Howmet has been allocated responsibility, and Howmet may not be able to satisfy its indemnification obligations in the future.
Pursuant to the separation agreement and certain other agreements between ParentCo and us, each party has agreed to indemnify the other for certain liabilities, in each case for uncapped amounts. Indemnities that we may be required to provide
34

TABLE OF CONTENTS
Howmet 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 Howmet 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 furtherance of our operating business. Further, the indemnities from Howmet for our benefit may not be sufficient to protect us against the full amount of such liabilities, and Howmet may not be able to fully satisfy its indemnification obligations.
Moreover, even if we ultimately succeed in recovering from Howmet any amounts for which we are held liable, we may be temporarily required to bear these losses ourselves. Each of these risks could negatively affect our business, results of operations and financial condition.
Howmet may fail to perform under various transaction agreements that were executed as part of the separation, or we may fail to have necessary systems and services in place when certain of the transaction agreements expire.
In connection with the separation and prior to the distribution, we and ParentCo have entered into the separation agreement and various other agreements, including a tax matters agreement, an employee matters agreement, intellectual property license agreements, an agreement relating to the Davenport plant, metal supply agreements and real estate and office leases. The separation agreement, the tax matters agreement and the employee matters agreement, together with the documents and agreements by which the internal reorganization was effected, determines the allocation of assets and liabilities between the companies following the separation for those respective areas and includes any necessary indemnifications related to liabilities and obligations. We will rely on Howmet to satisfy its performance and payment obligations under these agreements. If Howmet is unable or unwilling to satisfy its obligations under these agreements, including its indemnification obligations, we could incur operational difficulties and/or losses. If we do not have in place our own systems and services, or if we do not have agreements with other providers with respect to any of these services once certain transaction agreements expire, we may not be able to operate our business effectively, and our profitability may decline.
The terms of our agreements with ParentCo could be less beneficial than the terms we may have otherwise received from unaffiliated third parties.
The agreements we entered into with ParentCo in connection with the separation, including the separation agreement, a tax matters agreement, an employee matters agreement, intellectual property license agreements, an agreement relating to the Davenport plant, metal supply agreements and real estate and office leases, were prepared in the context of the separation while we were still a wholly owned subsidiary of ParentCo. Accordingly, during the period in which the terms of those agreements were prepared, we did not have an independent Board of Directors or a management team that was independent of ParentCo. As a result, the terms of those agreements may not reflect terms that would have resulted from arm’s-length negotiations between unaffiliated third parties.
If the distribution, together with certain related transactions, does not qualify as a transaction that is generally tax-free for U.S. federal income tax purposes, we, as well as Howmet and Howmet's stockholders, could be subject to significant tax liabilities, and, in certain circumstances, we could be required to indemnify Howmet for material taxes and other related amounts pursuant to indemnification obligations under the tax matters agreement.
It was a condition to the distribution that ParentCo receive an opinion of its outside counsel, satisfactory to the ParentCo 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 U.S. Internal Revenue Code. 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 of ParentCo and us, including those relating to the past and future conduct of ParentCo and us. If any of these facts, assumptions, representations, statements or undertakings was, or becomes, inaccurate or incomplete, or if ParentCo breaches its or we breach any of our respective 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 receipt of the opinion of counsel, the IRS could determine that the distribution 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 represented 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 is no assurance that the IRS will not assert that the distribution and/or certain related transactions do not qualify for tax-free treatment for U.S. federal income tax purposes or that a court would not sustain such a challenge. In the
35

TABLE OF CONTENTS
event the IRS were to prevail with such challenge, we, as well as ParentCo and ParentCo’s stockholders, could be subject to significant U.S. federal income tax liability.
If the distribution were to fail 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 U.S. Internal Revenue Code, in general, for U.S. federal income tax purposes, ParentCo would recognize taxable gain as if it had sold the our common stock in a taxable sale for its fair market value, and ParentCo stockholders who received our 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 the tax matters agreement entered into between ParentCo and us in connection with the separation, we generally are required to indemnify Howmet for any taxes resulting from the separation (and any related costs and other damages) to the extent such amounts resulted from (1) an acquisition of all or a portion of our equity securities or assets, whether by merger or otherwise (and regardless of whether we participated in or otherwise facilitated the acquisition), (2) certain of our other actions or failures to act, or (3) any of our 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. Any such indemnity obligations could be material. In addition, we, Howmet, and the respective subsidiaries may continue to incur certain tax costs in connection with the separation, including non-U.S. tax costs resulting from transactions (including the internal reorganization) in non-U.S. jurisdictions, which may be material.
We may not be able to engage in desirable capital-raising or strategic transactions following the separation.
Under current U.S. federal income tax law, a spin-off that otherwise qualifies for tax-free treatment can be rendered taxable to the parent corporation and its stockholders as a result of certain post-spin-off transactions, including certain acquisitions of shares or assets of the spun-off corporation. To preserve the tax-free treatment of the separation and the distribution, and in addition to our indemnity obligations described above, the tax matters agreement restricts us, for the two-year period following the distribution, except in specific circumstances, from, among other things: (1) entering into any transaction pursuant to which all or a portion of our shares of stock would be acquired, whether by merger or otherwise; (2) issuing equity securities beyond certain thresholds; (3) repurchasing our shares of stock other than in certain open-market transactions; and (4) ceasing to actively conduct certain of our businesses. The tax matters agreement also prohibits us from taking or failing to take any other action that would prevent the distribution and certain related transactions from qualifying 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 U.S. Internal Revenue Code. These restrictions may limit our ability to pursue certain equity issuances, strategic transactions, repurchases or other transactions that we may believe to be in the best interests of our stockholders or that might increase the value of our business.
The transfer to us of certain contracts, permits and other assets and rights required the consents or approvals of, or provide other rights to, third parties and governmental authorities. If such consents or approvals were not obtained, we may not be entitled to the benefit of such contracts, permits and other assets and rights, which could increase our expenses or otherwise harm our business and financial performance.
The separation agreement provides that certain contracts, permits and other assets and rights were to be transferred from ParentCo or its subsidiaries to us or our subsidiaries in connection with the separation. The transfer of certain of these contracts, permits and other assets and rights required consents or approvals of third parties or governmental authorities or provide other rights to third parties. In addition, in some circumstances, we and ParentCo were joint beneficiaries of contracts, and the consents of third parties were required in order to split or separate the existing contracts or the relevant portion of the existing contracts to us or ParentCo.
If consents or approvals were not obtained in connection with the separation, the counter-parties may seek to terminate contracts or obtain more favorable contractual terms from us, which, for example, could take the form of adverse price changes, require us to expend additional resources in order to obtain the services or assets previously provided under the contract, or require us to seek arrangements with new third parties. As a result, we may be unable to benefit from the permits, assets and contractual commitments that were intended to be allocated to us as part of the separation from ParentCo, and we may be required to seek alternative arrangements to obtain services and assets which may be more costly and/or of lower quality. Any of these events could negatively impact our business, financial condition, results of operations and cash flows.

TABLE OF CONTENTS
Risks Related to Our Common Stock
We cannot be certain that an active trading market for our common stock will be sustained and our stock price may fluctuate significantly.
For many reasons, including the risks identified in this Annual Report on Form 10-K, the market price of our common stock may be volatile. These factors may result in short-term or long-term negative pressure on the value of our common stock. The market price of our common stock may fluctuate significantly due to a number of factors, some of which may be beyond our control, including:
•sales of a significant number of our shares or other shifts in our investor base;
•actual or anticipated fluctuations in our operating results;
•changes in earnings estimated by securities analysts or our ability to meet those estimates;
•the operating and stock price performance of comparable companies;
•changes to the regulatory and legal environment under which we operate;
•actual or anticipated fluctuations in commodities prices; and
•domestic and worldwide economic conditions.
Actions of activist shareholders could have an adverse effect on our business.
Companies across a variety of industries are experiencing an increase in shareholder activism, particularly shareholder proposals regarding environmental sustainability, diversity and inclusion, and governance matters. If we are required to respond to shareholder proposals (including the implementation of any proposals), proxy contests or other actions by activist shareholders, we could incur significant expense, disruptions to our operations and diversion of the attention of management and our employees. In addition, perceived uncertainties as to our future direction, strategy or leadership created as a consequence of activist shareholder initiatives may result in reputational damage, which could negatively impact relationships with customers, suppliers and strategic partners, impair our ability to attract and retain employees, and cause volatility in our stock price.
Individual stockholders' percentage of ownership of our common stock may be diluted in the future.
In the future, individual stockholders' percentage of ownership in our common stock may be diluted because of equity issuances for acquisitions, capital market transactions or otherwise. In addition, from time to time, we grant stock-based awards to our directors, officers and employees. Such awards will have a dilutive effect on the number of our shares outstanding, and therefore on our earnings per share, which could adversely affect the market price of our common stock.
We cannot guarantee the timing, amount or payment of dividends on our common stock.
On April 1, 2020, our Board of Directors determined to defer initiating a dividend in light of current uncertainties resulting from the COVID-19 pandemic. The initiation, timing, declaration, amount and payment of future dividends to our stockholders falls within the discretion of our Board of Directors. The Board of Directors’ decisions regarding the payment of dividends depends on many factors, such as our financial condition, earnings, capital requirements, debt service obligations, covenants associated with certain of our debt service obligations, industry practice, legal requirements, regulatory constraints and other factors that our Board of Directors deems relevant. For more information, see Part II, Item 5. “Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities.”
Anti-takeover provisions could enable us to resist a takeover attempt by a third party and limit the power of our stockholders.
Our amended and restated certificate of incorporation and amended and restated 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 our Board of Directors rather than to attempt a hostile takeover. These provisions include, among others:
•the ability of our remaining directors to fill vacancies on our Board of Directors that do not arise as a result of removal by stockholders;
•limitations on stockholders’ ability to call a special stockholder meeting;
•rules regarding how stockholders may present proposals or nominate directors for election at stockholder meetings; and
•the right of our Board of Directors to issue preferred stock without stockholder approval.
37

TABLE OF CONTENTS
In addition, we are subject to Section 203 of the Delaware General Corporate Law (the “DGCL”), which could have the effect of delaying or preventing a change of control that you may favor. Section 203 provides that, subject to limited exceptions, persons that acquire, or are affiliated with persons that acquire, more than 15% of the outstanding voting stock of a Delaware corporation may not engage in a business combination with that corporation, including by merger, consolidation or acquisitions of additional shares, for a three-year period following the date on which that person or any of its affiliates becomes the holder of more than 15% of the corporation’s outstanding voting stock.
We believe these provisions will protect our stockholders from coercive or otherwise unfair takeover tactics by requiring potential acquirers to negotiate with our Board of Directors and by providing our Board of Directors with more time to assess any acquisition proposal. These provisions are not intended to make us immune from takeovers; however, these provisions will apply even if the offer may be considered beneficial by some stockholders and could delay or prevent an acquisition that our Board of Directors determines is not in our best interests and our stockholders’ best interests. These provisions may also prevent or discourage attempts to remove and replace incumbent directors.
In addition, an acquisition or further issuance of our stock could trigger the application of Section 355(e) of the U.S. Internal Revenue Code, causing the distribution to be taxable to ParentCo. Under the tax matters agreement, we would be required to indemnify ParentCo for the resulting tax, and this indemnity obligation might discourage, delay or prevent a change of control that our stockholders may consider favorable.
Our amended and restated certificate of incorporation designates the state courts within the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could discourage lawsuits against us and our directors and officers.
Our amended and restated certificate of incorporation provides that unless the Board of Directors otherwise determines, the state courts within the State of Delaware (or, if no state court located within the State of Delaware has jurisdiction, the federal district court for the District of Delaware) will be the sole and exclusive forum for any derivative action or proceeding brought on behalf of us, any action asserting a claim for or based on a breach of a fiduciary duty owed by any of our current or former directors or officers to us or our stockholders, including a claim alleging the aiding and abetting of such a breach of fiduciary duty, any action asserting a claim against us or any of our current or former directors or officers arising under any provision of the DGCL or our amended and restated certificate of incorporation or amended and restated bylaws, any action asserting a claim relating to or involving us governed by the internal affairs doctrine, or any action asserting an “internal corporate claim” as that term is defined in Section 115 of the DGCL.
To the fullest extent permitted by law, this exclusive forum provision applies to state and federal law claims, including claims under the federal securities laws, including the Securities Act of 1933 and the Securities Exchange Act of 1934, each as amended, although our stockholders will not be deemed to have waived our compliance with the federal securities laws and the rules and regulations thereunder. The enforceability of similar choice of forum provisions in other companies’ certificates of incorporation has been challenged in legal proceedings, and it is possible that, in connection with claims arising under federal securities laws or otherwise, a court could find the exclusive forum provision contained in the amended and restated certificate of incorporation to be inapplicable or unenforceable.
This exclusive forum provision may limit the ability of our stockholders to bring a claim in a judicial forum that our stockholders find favorable for disputes with us or our directors or officers, which may discourage such lawsuits against us and our directors and officers. Alternatively, if a court were to find this exclusive forum provision inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings described above, we may incur additional costs associated with resolving such matters in other jurisdictions, which could negatively affect our business, results of operations and financial condition.

On April 1, 2020, Arconic completed its separation from ParentCo. See Item 1. Business. “Overview-The Separation Transaction.”
As of February 17, 2022, there were approximately 9,000 holders of record of shares of the Company's common stock. Because many of Arconic’s shares are held by brokers and other institutions on behalf of stockholders, the Company is unable to estimate the total number of stockholders represented by these recordholders.
Arconic did not declare or pay any dividends from April 1, 2020 through December 31, 2021. The timing, declaration, amount of, and payment of any dividends is within the discretion of the Company’s Board of Directors and depends upon many factors, including Arconic’s financial condition, earnings, capital requirements of Arconic’s operating subsidiaries, covenants associated with certain of Arconic’s debt service obligations, legal requirements, regulatory constraints, industry practice, ability to access capital markets, and other factors deemed relevant by the Company’s Board of Directors. Moreover, if Arconic determines to pay any dividends in the future, there can be no assurance that Arconic will continue to pay such dividends or the amount of such dividends.

Overview
Our Business
Arconic Corporation (“Arconic” or the “Company”) is a manufacturer of fabricated aluminum products, including sheet and plate, extrusions, and architectural products and systems, with a primary focus on the ground transportation, aerospace, building and construction, industrial products, and packaging end markets. The Company has 21 primary operating locations in 8 countries around the world, situated in the United States, Canada, China, France, Germany, Hungary, Russia, and the United Kingdom.
The Separation
On February 8, 2019, ParentCo announced that its Board of Directors approved a plan to separate into two standalone, publicly-traded companies (the “Separation”). The spin-off company, later named Arconic Corporation, was to include the rolled aluminum products, aluminum extrusions, and architectural products operations of ParentCo, as well as the Latin America extrusions operations sold in April 2018, (collectively, the “Arconic Corporation Businesses”). The existing publicly traded company, ParentCo, was to continue to own the engine products, engineered structures, fastening systems, and forged wheels operations (collectively, the “Howmet Aerospace Businesses”).
The Separation was subject to a number of conditions, including, but not limited to: final approval by ParentCo’s Board of Directors (see below); receipt of an opinion of legal counsel (received on March 31, 2020) regarding the qualification of the
41

TABLE OF CONTENTS
distribution, together with certain related transactions, as a “reorganization” within the meaning of Sections 335 and 368(a)(1)(D) of the U.S. Internal Revenue Code (i.e., a transaction that is generally tax-free for U.S. federal income tax purposes); and the U.S. Securities and Exchange Commission (the “SEC”) declaring effective a Registration Statement on Form 10, as amended, filed with the SEC on February 13, 2020 (effectiveness was declared by the SEC on February 13, 2020).
On February 5, 2020, ParentCo’s Board of Directors approved the completion of the Separation by means of a pro rata distribution by ParentCo of all of the outstanding shares of common stock of Arconic to ParentCo common stockholders of record as of the close of business on March 19, 2020 (the “Record Date”). At the time of the Separation, ParentCo common stockholders were to receive one share of Arconic common stock for every four shares of ParentCo common stock (the “Separation Ratio”) held as of the Record Date (ParentCo common stockholders were to receive cash in lieu of fractional shares).
In connection with the Separation, as of March 31, 2020, Arconic and Howmet Aerospace entered into several agreements to implement the legal and structural separation between the two companies; govern the relationship between Arconic and Howmet Aerospace after the completion of the Separation; and allocate between Arconic and Howmet Aerospace various assets, liabilities, and obligations, including, among other things, employee benefits, environmental liabilities, intellectual property, and tax-related assets and liabilities. These agreements included a Separation and Distribution Agreement, Tax Matters Agreement, Employee Matters Agreement, and certain Patent, Know-How, Trade Secret License and Trademark License Agreements. The Separation and Distribution Agreement identified the assets to be transferred, the liabilities to be assumed, and the contracts to be transferred to each of Arconic and Howmet Aerospace as part of the Separation, and provided for when and how these transfers and assumptions were to occur.
On April 1, 2020 (the “Separation Date”), the Separation was completed and became effective at 12:01 a.m. Eastern Daylight Time. To effect the Separation, ParentCo undertook a series of transactions to separate the net assets and certain legal entities of ParentCo, resulting in a cash payment of $728 to ParentCo by Arconic from a portion of the aggregate net proceeds of previously executed financing arrangements (see Financing Activities in Liquidity and Capital Resources below). In connection with the Separation, 109,021,376 shares of Arconic common stock were distributed to ParentCo stockholders. This was determined by applying the Separation Ratio to the 436,085,504 shares of ParentCo’s outstanding common stock as of the Record Date. “Regular-way” trading of Arconic’s common stock began with the opening of the New York Stock Exchange on April 1, 2020 under the ticker symbol “ARNC.” Arconic’s common stock has a par value of $0.01 per share.
ParentCo incurred costs to evaluate, plan, and execute the Separation, and Arconic was allocated a pro rata portion of these costs based on segment revenue (see Cost Allocations below). ParentCo recognized $38 from January 2020 through March 2020 and $78 in 2019 for such costs, of which $18 and $40, respectively, was allocated to Arconic. The allocated amounts were included in Selling, general administrative, and other expenses on Arconic’s Statement of Consolidated Operations.
Basis of Presentation. The Consolidated Financial Statements of Arconic are prepared in conformity with accounting principles generally accepted in the United States of America (GAAP). In accordance with GAAP, certain situations require management to make estimates based on judgments and assumptions, which 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 revenues and expenses during the reporting periods. Actual results could differ from those estimates upon subsequent resolution of identified matters. These estimates are based on historical experience and, in some cases, assumptions based on current and future market experience, including considerations related to the coronavirus (COVID-19) pandemic. Management has made its best estimates using all relevant information available at the time, but it is possible that these estimates will differ from actual results and affect the Consolidated Financial Statements in future periods and potentially require adverse adjustments to the recoverability of goodwill and long-lived assets, the realizability of deferred tax assets and other judgments and estimations and assumptions that may be impacted by the COVID-19 pandemic.
Prior to the Separation Date, Arconic did not operate as a separate, standalone entity. Arconic’s operations were included in ParentCo’s financial results. Accordingly, for all periods prior to the Separation Date, the Consolidated Financial Statements of Arconic were prepared from ParentCo’s historical accounting records and were presented on a standalone basis as if the Arconic Corporation Businesses had been conducted independently from ParentCo. Such Consolidated Financial Statements include the historical operations that were considered to comprise the Arconic Corporation Businesses, as well as certain assets and liabilities that were historically held at ParentCo’s corporate level but were specifically identifiable or otherwise attributable to Arconic.
Cost Allocations. The description and information on cost allocations is applicable for all periods included in Arconic’s Consolidated Financial Statements prior to the Separation Date.
The Consolidated Financial Statements of Arconic include general corporate expenses of ParentCo that were not historically charged to the Arconic Corporation Businesses for certain support functions that were provided on a centralized
42

TABLE OF CONTENTS
basis, such as expenses related to finance, audit, legal, information technology, human resources, communications, compliance, facilities, employee benefits and compensation, and research and development activities. These general corporate expenses were included on Arconic’s Statement of Consolidated Operations within Cost of goods sold, Selling, general administrative and other expenses, and Research and development expenses. These expenses were allocated to Arconic on the basis of direct usage when identifiable, with the remainder allocated based on the Arconic Corporation Businesses’ segment revenue as a percentage of ParentCo’s total segment revenue, as reported in the respective periods.
All external debt not directly attributable to Arconic was excluded from Arconic’s Consolidated Balance Sheet. Financing costs related to these debt obligations were allocated to Arconic based on the ratio of capital invested by ParentCo in the Arconic Corporation Businesses to the total capital invested by ParentCo in both the Arconic Corporation Businesses and the Howmet Aerospace Businesses, and were included on Arconic’s Statement of Consolidated Operations within Interest expense.
The following table reflects the allocations described above:

|  | 2020 |  | 2019
Cost of goods sold(1) |  | $ | — |  |  | $ | 14 |
Selling, general administrative, and other expenses(2) |  | 25 |  |  | 115 |
Research and development expenses |  | — |  |  | 11 |
Provision for depreciation and amortization |  | 1 |  |  | 10 |
Restructuring and other charges |  | 2 |  |  | 7 |
Interest expense |  | 28 |  |  | 115 |
Other (income), net |  | (5) |  |  | (6) |

__________________
(1) For all periods presented, amount principally relates to an allocation of expenses for ParentCo’s retained pension and other postretirement benefit obligations associated with closed and sold operations.
(2) In 2020 (January through March) and 2019, amount includes an allocation of $18 and $40, respectively, for costs incurred by ParentCo associated with the Separation (see above).
Management believes the assumptions regarding the allocation of ParentCo’s general corporate expenses and financing costs were reasonable.
Nevertheless, the Consolidated Financial Statements of Arconic may not include all of the actual expenses that would have been incurred and may not reflect Arconic’s consolidated results of operations, financial position, and cash flows had it been a standalone company during the periods prior to the Separation Date. Actual costs that would have been incurred if Arconic had been a standalone company would depend on multiple factors, including organizational structure, capital structure, and strategic decisions made in various areas, including information technology and infrastructure. Transactions between Arconic and ParentCo, including sales to the Howmet Aerospace Businesses, were presented as related party transactions in Arconic’s Consolidated Financial Statements and were considered to be effectively settled for cash at the time the transaction was recorded. The total net effect of the settlement of these transactions was reflected on Arconic’s Statement of Consolidated Cash Flows as a financing activity and on the Company’s Consolidated Balance Sheet as Parent Company net investment.
Management Review of 2021 and Outlook for the Future
Arconic had a strong first full year of operations as a stand-alone company in 2021, despite the challenges of an array of headwinds. Segment adjusted EBITDA* grew 17% over 2021 driven by most of our end-markets showing double-digit revenue growth despite aerospace volumes being down. The Company was able to optimize its product mix to help compensate for changes in automotive demand related to semiconductor chip shortages and changes in staffing availability due to the pandemic. We implemented actions to offset inflation in alloying materials, energy prices and freight costs through increased pricing and productivity measures. In the Rolled Products segment, 2021 Segment Adjusted EBITDA exceeded 2019 levels (which were prior to pandemic impacts), despite the lower aerospace and automotive build rates. We secured long-term contracts for over $2,000 in aerospace sales, signed agreements for approximately $1,500 in North American packaging sales from 2022-2024, and captured content on 23 new automotive or light commercial vehicle platforms including a number of full-electric vehicles. We executed on a capital allocation strategy to reduce liabilities associated with pension and other postretirement benefits and effectively manage environmental obligations, positioning the Company for expected future growth in cash generation. We also repurchased $161 of shares of the Company’s common stock and initiated two organic capital projects in the Rolled Products segment that are expected to drive future EBITDA growth starting in 2023.

TABLE OF CONTENTS
In 2021, Sales of $7,504 rose 32% from 2020, reflecting higher aluminum prices and volume improvements in all our end markets except aerospace. The Company recorded a net loss of $397, or $3.65 per share, compared to a net loss of $109, or $1.00 per share, in 2020. The 2021 results included a pre-tax charge of $549 ($423 after-tax) for the settlement of certain employee retirement benefits related to the partial annuitization of U.S. pension plan obligations in April 2021, and a pre-tax charge of $65 ($65 after-tax) for the impairment of goodwill associated with the Extrusions reporting unit in the fourth quarter of 2021.
We ended the year with a cash balance of $335, and total liquidity of $1,125 (comprised of Cash and cash equivalents of $335 and undrawn availability of $790 under the Company’s ABL Credit Agreement). We increased the aggregate principal amount of the Company’s ABL Credit Agreement on February 16, 2022 from $800 to $1,200, reflecting the increase in collateral base due to volume growth and higher aluminum prices.
As we look forward to 2022 and beyond, we anticipate volumes will benefit from the ongoing ramp up of our Tennessee can sheet operations, improvement in the aerospace end-market, and growth in ground transportation as our automotive customers anticipate that semiconductor chip availability is expected to ease throughout the year. Based on current internal and external projections of build rates and leading indicators in the markets we serve, our expectations for sales by major end market, excluding the impact of changes in aluminum prices, in 2022 follow. For the ground transportation end market, we expect sales to increase by approximately 10% to 15% in 2022 compared with 2021, driven by our customers expecting improvements in semiconductor chip availability. Automotive sales are expected to increase from 2021 levels, while commercial transportation sales are expected to remain strong but are not expected to grow at the same pace as they did in 2021. For the industrial products end market, we anticipate sales to grow by approximately 5% to 10% in 2022 compared with 2021, driven by continued strong pricing and demand due to the impact of ongoing U.S. trade actions. Our volume growth may be constrained by the need to pivot capacity that served industrial products in 2021 back to ground transportation later in 2022. For the building and construction end market, we anticipate sales to increase by approximately 5% to 10% in 2022 compared with 2021, driven by increased non-residential construction activity, but expected to be challenged in the near term related to supply chain constraints, pricing, and labor issues creating uncertainty for our customers. For the packaging end market, we expect sales to increase by approximately 40% to 45% in 2022 compared with 2021, as North American can sheet ramps up to full capacity in the first half of 2022 and facilities in Russia and China continue to serve strong global markets. For the aerospace end market, we expect sales to grow by approximately 25% to 35% from 2021, as the supply chain is expected to be destocked in 2022 and aircraft build rates are expected to increase.

Legal Proceedings Involving our Samara Facility
Our subsidiaries that own and operate our facility located in Samara, Russia are, and have been since the Separation, subject to proceedings initiated by Russian regulatory authorities as a result of alleged violations of Russian Federal Law No. 57-FZ. In connection with these proceedings, authorities have imposed injunctions prohibiting, among other actions, the payment of dividends, placement of bonds, amendments to organizational documents, and changes to the subsidiaries’ chief executive officer and board of directors. See Note T to the Consolidated Financial Statements in Part II, Item 8. “Financial Statements and Supplementary Data” under the caption “Contingencies and Commitments—Contingencies—Litigation—Federal Antimonopoly Service Of The Russian Federation Litigation” for additional information regarding the proceedings. The proceedings and underlying claims may not be resolved favorably, are likely to continue to be delayed, may be resolved in a manner that results in permanent injunctions similar to or more restrictive than the current injunctions, and could result in a decision or a requirement to divest some or all of the assets located at the Samara facility.
Approximately $79, or 24%, of Arconic’s Cash and cash equivalents at December 31, 2021 is currently held in Russia and is not available for dividends. Cash and cash equivalents held in Russia represented 7% of Arconic’s total liquidity at December 31, 2021. In addition, approximately $968, or 16% of third-party sales (including packaging, industrial products, aerospace, and defense), and approximately $87, or 13% of Segment Adjusted EBITDA, for the Rolled Products segment for the year ended December 31, 2021 were generated by our Samara, Russia facility. We cannot at this time reasonably estimate the likelihood or timing of any resolution of the regulatory proceedings or underlying claims, whether such resolution would include the removal of the injunctions or the imposition of additional restrictions, or whether we would divest assets related to the Samara facility. The potential impacts of an unfavorable resolution of the proceedings and underlying claims include:
•continued unavailability of funds for the payment of dividends to Arconic Corporation;
•decreases in or loss of third-party sales and Segment Adjusted EBITDA generated by our Samara facility;
•restrictions on capital investments in the facility;
•losses on any potential divestiture;
44

TABLE OF CONTENTS
•the inability of other Arconic facilities to assume capacity to offset decreases in sales or Segment Adjusted EBIDTA or to assume potential divested capacity; and
•increased expenses related to relocation of capacity to other facilities.
Any of the foregoing could have a significant indirect impact on the performance of our other locations. In addition, any impact on our ability to fulfill delivery obligations could subject us to reputational harm and potential litigation involving customers and suppliers. Continued restrictions on our operation of the Samara facility would have a material adverse effect on our financial condition, results of operations or cash flows.
COVID-19 Pandemic
Our operations and financial results have been, and may continue to be, adversely affected by the COVID-19 pandemic. As a result of the COVID-19 pandemic, several of our automotive and aerospace customers temporarily suspended operations at different points throughout 2020. While many of our customers have resumed operations as it relates to the COVID-19 pandemic, we are unable to estimate with certainty at this time the status, frequency, or duration of any potential reoccurrences of customer shutdowns, or the duration or extent of resumed operations. Due to the impacts of the COVID-19 pandemic on our customers, we are experiencing, and expect to continue experiencing, lower demand and volume for our products. These trends may lead to charges, impairments and other adverse financial impacts over time. The impact on our business, results of operations, financial condition, liquidity, and/or cash flows will be magnified if the disruption from the COVID-19 pandemic continues for an extended period.
We believe that our diverse end markets and geographic composition mitigate a portion of the impact on the Company from any singular area of decline. Additionally, our operating footprint benefits from a highly variable cost structure and we are actively managing operations to effectively flex activity to respond to changing automotive and aerospace market conditions. However, the geographic locations in which our products are manufactured, distributed or sold are in varying stages of continued restrictions or lifting of restrictions, and the status of restrictions in certain areas may change on short notice. Because we rely on supply chain continuity, restrictions in one location may materially impact operations in multiple locations, and the impact of the COVID-19 pandemic in one location may have a disproportionate effect on our operations in the future.
The safety of our employees is our highest priority. We heightened measures at all of our locations to maintain strict hygiene, increase social distancing, and enable employees to work remotely where possible. In response to market conditions we implemented a series of proactive actions starting in April 2020 to mitigate the impacts of the COVID-19 pandemic on the Company, including the following:
•deferred initiating a dividend on common stock;
•reduced the CEO’s salary and the Board of Directors’ cash compensation by 30%*;
•reduced salaries for senior-level management by 20% and for all other salaried employees by 10%*;
•restructuring of the salaried workforce, reduction of 10%;
•idling of various production facilities based on market conditions within the regions where the Company operates;
•decreasing production and operating with a reduced labor force through shortened work weeks, shift reductions, layoffs, and the elimination of temporary workers and contractors at U.S.-based rolling and extrusion facilities;
•implementing a combination of modified schedules, adjusted work hours, lower costs, and/or delayed raises at all rolling mill facilities in Europe, China and Russia;
•suspended the 401(k) match program for U.S. salaried employees*; and
•reducing capital expenditures by approximately $50, or approximately 30%.
*Effective September 1, 2020, the Company restored both the salaries of all salaried employees and the 401(k) match of all salaried U.S. employees, including executive officers, to the levels in effect prior to the actions described above. Also effective September 1, 2020, the Company restored the annual cash retainers payable to the non-employee members of the Company’s Board of Directors to the levels in effect prior to the previous reduction described above.
The foregoing measures from our cash conservation program resulted in actual cost savings of approximately $160, comprised of $100 in temporary savings (i.e., 2020 only) and $60 in permanent savings, as well as an additional $50 for capital expenditure reductions, from April 2020 through December 2020. In 2021, an additional $40 in permanent savings were realized under this program. While we anticipate incremental cost savings in future periods related to the measures that resulted in permanent cost savings during 2021 and 2020, we may not achieve such savings. In addition, we may determine that it is necessary to modify or rescind cost-saving actions, in which case certain of the realized permanent cost savings may not continue and/or any anticipated incremental cost savings would not be fully realized. Further disruptions and uncertainties related to the COVID-19 pandemic could require us to take additional cost-saving actions or to modify or rescind current cost-saving actions, make additional modifications to our strategic plans and/or incur additional expenses as part of our continued response to the COVID-19 pandemic. The cost-savings measures taken to date, and any cost-cutting measures we may need to
45

TABLE OF CONTENTS
take in the future, could have a material and adverse effect on our business, results of operations, financial condition, liquidity, and/or cash flows.
While we are continuing to evaluate the impact of this global event, our liquidity and financial position remains strong despite the COVID-19 pandemic’s impact to our business. Our business is flexible and we have demonstrated a robust and agile cash management program, and together with potential future cash conservation actions, we believe we have adequate liquidity to operate the Company over the next twelve months.
The timing for the Company and/or our customers resuming operations and the levels of operations experienced before the COVID-19 pandemic depend on numerous factors beyond the Company’s control, including, among other things: the revision of governmental quarantine, shelter in place or similar social distancing orders or guidelines; the occurrence and magnitude of future outbreaks; the availability of vaccines or other medical remedies and preventive measures; the location of facilities; and determinations regarding, among other things, health and safety, demand for specific products, and broader economic conditions. We are continuing to evaluate the impact this global event may have on the Company’s future results of operations, financial condition, liquidity, and cash flows.
See Part I. Item 1A. “Risk Factors” for additional information regarding the continuing impact of the COVID-19 pandemic on our operations.
Results of Operations
The discussion and analysis that follows includes a comparison of Arconic’s results of operations between the 2021 and 2020 annual periods for both the total company and each reportable segment. Please refer to the Results of Operations section included in Management’s Discussion and Analysis of Financial Condition and Results of Operations in Part II Item 7 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 (filed on February 23, 2021) for a discussion and analysis of Arconic’s results of operations between the 2020 and 2019 annual periods for both the total company and each reportable segment.
Earnings Summary
Sales. Sales were $7,504 in 2021 compared to $5,675 in 2020, an increase of $1,829, or 32%. The increase was principally due to higher aluminum prices driven by a rise in both the average LME price and regional premiums, improved volumes in all end markets except aerospace as recovery from the COVID-19 pandemic continues, and higher product pricing. These positive impacts were slightly offset by both lower volume and unfavorable product mix due to depressed sales to the aerospace end market, the negative impact of the semiconductor chip shortage affecting the automotive component of the ground transportation end market, and labor shortages at several North America operations due to COVID-19-related quarantines.
In March 2021, the Company entered into a settlement agreement with a customer related to the terms of an existing long-term contract. As a result, the customer agreed to pay Arconic $18, which will be recognized over the applicable three-year period. Accordingly, the Company’s sales in 2021 included $12 associated with this settlement.
Cost of Goods Sold. COGS was $6,573 in 2021 compared to $4,862 in 2020, an increase of $1,711, or 35%. COGS as a percentage of Sales was 87.6% in 2021 compared to 85.7% in 2020. This percentage was negatively impacted by higher aluminum prices (underlying metal price is contractually passed-through to most customers at cost), unfavorable product mix driven by depressed sales to the aerospace end market, and the impact of the semiconductor chip shortage affecting the automotive component of the ground transportation market. These negative impacts were partially offset by higher product pricing. Net cost savings principally resulting from operational productivity and the absence of below normal absorption of fixed costs that occurred in 2020 driven by significantly lower production levels as a result of the COVID-19 pandemic, were offset by higher costs for labor (see Labor costs below), energy, transportation, and alloying materials.
Selling, General Administrative, and Other Expenses. SG&A expenses were $247, or 3.3% of Sales, in 2021 compared to $258, or 4.5% of Sales, in 2020. The decrease of $11, or 4%, was largely attributable to the absence of an allocation ($18) of costs incurred for the Separation (see Cost Allocations under The Separation above), somewhat offset by higher labor costs (see Labor costs below).
Research and Development Expenses. R&D expenses were $34 in 2021 compared to $36 in 2020. The decrease was primarily driven by cost reduction efforts initiated in 2020.
Labor costs—The following description is applicable to COGS, SG&A, and R&D in the aggregate. Beginning in April 2020, management implemented a series of proactive actions to mitigate the impacts of the COVID-19 pandemic on the
46

TABLE OF CONTENTS
Company. Many of these actions impacted both business unit and corporate employees resulting in the Company experiencing lower labor costs in 2020. These actions included the following:
•idled various production facilities based on market conditions within the regions where the Company operates;
•decreased production and operating with a reduced labor force through shortened work weeks, shift reductions, layoffs, and the elimination of temporary workers and contractors at U.S.-based rolling and extrusion facilities;
•implemented a combination of modified schedules, adjusted work hours, lower costs, and/or delayed raises at all rolling mill facilities in Europe, China, and Russia;
•reduced the CEO’s salary and the Board of Directors’ cash compensation by 30%;
•reduced salaries for senior-level management by 20% and for all other salaried employees by 10%; and
•suspended the 401(k) match program for U.S. salaried employees.
Effective September 1, 2020, the Company restored both the salaries of all salaried employees and the 401(k) match of all salaried U.S. employees, including executive officers, to the levels in effect prior to the actions described above. Also effective September 1, 2020, the Company restored the annual cash retainers payable to the non-employee members of the Company’s Board of Directors to the levels in effect prior to the previous reduction described above. Additionally, by the end of 2020 and throughout 2021, the Company’s production facilities were operating at significantly higher levels compared to earlier in 2020. As a result, the Company experienced higher labor costs in 2021 compared to 2020.
Provision for Depreciation and Amortization. The provision for depreciation and amortization was $253 in 2021 compared to $251 in 2020. The increase of $2 was mainly caused by new depreciation for assets placed into service in the second half of 2020 related to an automotive and industrial product expansion at the Company’s Tennessee rolling facility, somewhat offset by the absence of an impairment of abandoned projects and plant equipment ($6) and the absence of depreciation on assets that were impaired in prior periods, including certain assets at the Company’s primary research and development facility.
Impairment of Goodwill. In 2021, the Company recognized a charge of $65 in connection with its annual review of goodwill for impairment related to the Extrusions reporting unit. In accordance with Arconic’s accounting policy, this review is performed in the fourth quarter each calendar year. Accordingly, this charge was recognized in the fourth quarter of 2021. See Goodwill in Critical Accounting Policies and Estimates below for additional information.
Restructuring and Other Charges. In 2021 and 2020, Restructuring and other charges were comprised of a net charge of $624 and $188, respectively. See Note E to the Consolidated Financial Statements in Part II Item 8 of this Form 10-K for additional information.
Interest Expense. Interest expense was $100 in 2021 compared to $118 in 2020. The decrease of $18, or 15%, was primarily due to the absence of both a $28 allocation of ParentCo's financing costs in the period prior to Separation (see Cost Allocations under The Separation above) and $19 for the write-off and immediate expensing of debt issuance costs as a result of a debt refinancing in May 2020, partially offset by a higher amount of interest associated with both a $700 debt offering executed in May 2020 and a $600 debt offering completed in February 2020 and new interest related to a $300 debt offering executed in March 2021. See Financing Activities under Liquidity and Capital Resources below for additional information related to these financing transactions.
Other Expenses, Net. Other expenses, net was $67 in 2021 compared to $70 in 2020. See Note G to the Consolidated Financial Statements in Part II Item 8 of this Form 10-K for additional information.
(Benefit) Provision for Income Taxes. The Company’s effective tax rate, including discrete items, was 13.5% (benefit on a loss) in 2021 and 0.9% (provision on a loss) in 2020. See Note I to the Consolidated Financial Statements in Part II Item 8 of this Form 10-K for a reconciliation of the effective tax rate for each of these years to the U.S. federal statutory rate of 21%.
Segment Information
Arconic’s operations consist of three reportable segments: Rolled Products, Building and Construction Systems, and Extrusions. Segment performance under the Company’s management reporting system is evaluated based on several factors; however, the primary measure of performance is Segment Adjusted EBITDA (Earnings before interest, taxes, depreciation, and amortization).
The Company calculates Segment Adjusted EBITDA as Total sales (third-party and intersegment) minus each of (i) Cost of goods sold, (ii) Selling, general administrative, and other expenses, and (iii) and Research and development expenses, plus Stock-based compensation expense and Metal price lag. Arconic’s Segment Adjusted EBITDA may not be comparable to similarly titled measures of other companies’ reportable segments.
47

TABLE OF CONTENTS
Segment Adjusted EBITDA for all reportable segments totaled $757 in 2021, $648 in 2020, and $757 in 2019. The following information provides Sales and Segment Adjusted EBITDA for each reportable segment for each of the three years in the period ended December 31, 2021. See Note D to the Consolidated Financial Statements in Part II Item 8 of this Form 10-K for additional information.
Rolled Products

|  | 2021 |  | 2020 |  | 2019
Third-party sales |  | $ | 6,187 |  |  | $ | 4,335 |  |  | $ | 5,609 |
Intersegment sales |  | 33 |  |  | 19 |  |  | 25 |
Total sales |  | $ | 6,220 |  |  | $ | 4,354 |  |  | $ | 5,634 |

Third-party aluminum shipments (kmt) |  | 1,404 |  |  | 1,179 |  |  | 1,390 |

Overview. The Rolled Products segment produces aluminum sheet and plate for a variety of end markets. Sheet and plate are sold directly to customers and through distributors related to the aerospace, ground transportation, packaging, building and construction, and industrial products (mainly used in the production of machinery and equipment and consumer durables) end markets. While the customer base for flat-rolled products is large, a significant amount of sales of sheet and plate is to a relatively small number of customers. Prices for these products are generally based on the price of metal plus a premium for adding value to the aluminum to produce a semi-finished product, resulting in a business model in which the underlying price of metal is contractually passed-through to customers. Generally, the sales and costs and expenses of this segment are transacted in the local currency of the respective operations, which are the U.S. dollar and, to a lesser extent, each of the following: the Russian ruble, Chinese yuan, the euro, and the British pound.
Sales. Third-party sales for the Rolled Products segment increased $1,852, or 43%, in 2021 compared to 2020. The improvement was largely attributable to higher aluminum prices (see below), a net increase in volumes (see below), and favorable product pricing. These positive impacts were slightly offset by unfavorable product mix driven by depressed sales to the aerospace end market, which provides for the highest revenue per metric ton in this segment’s commercial portfolio, and labor shortages at several North America operations due to COVID-19-related quarantines.
The higher aluminum prices were mostly driven by a 45% rise in the average LME aluminum price and sharp increases in regional premiums, including a 118% improvement in the average Midwest premium (United States).
The net increase in volumes was largely attributable to most end markets served by this segment, including ground transportation (improvement in the automotive component of this market was lessened by the global semiconductor chip shortage), industrial products, and packaging. Each of these end markets have experienced varying levels of recovery from the economic impact of the COVID-19 pandemic. Additionally, volume related to the industrial products end market was favorably impacted by a U.S. trade case, which reached a final determination in March 2021, that imposes significant duties on the import of common alloy aluminum sheet. These higher volumes were slightly offset by decreased volume in the aerospace end market due to the economic impact of the COVID-19 pandemic. Year over year, all of the negative volume impact related to the aerospace end market was experienced in the first half of 2021.
In March 2021, the Company entered into a settlement agreement with a customer related to the terms of an existing long-term contract. As a result, the customer agreed to pay Arconic $18, which will be recognized over the applicable three-year period. Accordingly, in 2021, Rolled Products’ sales included $12 associated with this settlement.
Segment Adjusted EBITDA. Segment Adjusted EBITDA for the Rolled Products segment increased $128, or 24%, in 2021 compared to 2020. The improvement was primarily due to a net increase in volumes, favorable product pricing, and net cost savings (see below). These positive impacts were somewhat offset by unfavorable product mix driven by depressed sales to the aerospace end market, which historically provided for the highest margin per metric ton in this segment’s commercial portfolio. In the 2021 fourth quarter, this segment recorded a net adjustment of $10 (approximately $7 of which relates to prior quarters in 2021) related to write-downs of scrap inventory. The out-of-period amounts were not material to any interim or annual period.
Net cost savings were principally the result of the absence of below normal absorption of fixed costs that occurred in 2020 due to significantly lower production levels as a result of the COVID-19 pandemic, as well as operational productivity. These positive impacts were partially offset by higher costs for labor (see Labor costs under Results of Operations above) and direct materials, including energy, transportation, and alloying materials.

Building and Construction Systems

|  | 2021 |  | 2020 |  | 2019
Third-party sales |  | $ | 1,011 |  |  | $ | 963 |  |  | $ | 1,118 |
Segment Adjusted EBITDA |  | $ | 130 |  |  | $ | 137 |  |  | $ | 126 |

Overview. The Building and Construction Systems segment manufactures products that are used primarily in the non-residential building and construction end market. These products include integrated aluminum architectural systems and architectural extrusions, which are sold directly to customers and through distributors. A limited amount of this segment’s product sales is directly impacted by metal pricing, which is a pass-through to the related customers. Generally, the sales and costs and expenses of this segment are transacted in the local currency of the respective operations, which are the U.S. dollar and, to a lesser extent, each of the following: the euro, the British pound, and Canadian dollar.
Sales. Third-party sales for the Building and Construction Systems segment increased $48, or 5%, in 2021 compared to 2020. The improvement was primarily due to higher product pricing across the entire portfolio, increased metal pass-through pricing due to significant increases in aluminum prices, and favorable foreign currency movements due to a stronger euro. These positive impacts were somewhat offset by lower volumes due to decreased demand in North America as a result of the economic impact of the COVID-19 pandemic.
Segment Adjusted EBITDA. Segment Adjusted EBITDA for the Building and Construction Systems segment decreased $7, or 5%, in 2021 compared to 2020. The decline was principally driven by higher costs for direct materials, including aluminum and labor (see Labor costs under Results of Operations above), and lower volumes, mostly offset by higher product pricing.
Extrusions

|  | 2021 |  | 2020 |  | 2019
Third-party sales |  | $ | 306 |  |  | $ | 381 |  |  | $ | 550 |

Third-party aluminum shipments (kmt) |  | 35 |  |  | 40 |  |  | 60 |

Overview. The Extrusions segment produces a range of extruded and machined parts for the aerospace, ground transportation, and industrial products end markets. These products are sold directly to customers and through distributors. Prices for these products are generally based on the price of metal plus a premium for adding value to the aluminum to produce a semi-finished product, resulting in a business model in which the underlying price of metal is contractually passed-through to customers. Generally, the sales and costs and expenses of this segment are transacted in the local currency of the respective operations, which are the U.S. dollar and, to a lesser extent, the euro.
In the 2021 first quarter, management approved the idling of the casthouse at the Lafayette (Indiana) plant. Additionally, in the 2021 second quarter, management approved the idling of the remaining operations (primarily small presses) at the Chandler (Arizona) plant. These actions were deemed necessary to address the ongoing depressed demand related to the aerospace end market and identified operational inefficiencies in the Extrusions portfolio. The Lafayette casthouse action will occur in multiple phases and is expected to be completed by mid-2022. Ultimately, the casthouse function will be outsourced to third-party vendors. The Chandler action was completed in the 2021 third quarter. The commercial operations related to Chandler have been integrated into Lafayette for the foreseeable future. In 2021, the Company incurred certain charges related to these decisions such as inventory write-downs, severance costs, and customer qualification costs. These items were not material, individually or in the aggregate, and were reported in Corporate (i.e., not included in Extrusion’s Segment Adjusted EBITDA). The Company may temporarily restart one or more of the presses at Chandler over short periods of time to address customer demand requirements.
Sales. Third-party sales for the Extrusions segment decreased $75, or 20%, in 2021 compared to 2020. The decline was largely attributable to a net decrease in volumes, somewhat offset by higher aluminum prices. The net decrease in volumes was mainly caused by a drop in demand in the aerospace end market due to the impact of the COVID-19 pandemic on air travel, partially offset by improved demand in the ground transportation and industrial products end markets. Most of the negative volume impact related to the aerospace end market was experienced in the first half of 2021.
Segment Adjusted EBITDA. Segment Adjusted EBITDA for the Extrusions segment decreased $12 in 2021 compared to 2020. The decline was mostly related to a net decrease in volumes and higher costs for direct materials and labor (see Labor
49

costs under Results of Operations above), partially offset by the absence of costs ($12) related to both inventory write-downs and customer settlements.

_________________
(1)In preparation for the Separation, effective January 1, 2020, certain U.S. defined benefit pension and other postretirement plans previously sponsored by ParentCo were separated into standalone plans for both Arconic and Howmet Aerospace. Additionally, effective April 1, 2020, Arconic assumed a portion of the obligations associated with certain non-U.S. defined benefit pension plans that included participants related to both the Arconic Businesses and the Howmet Aerospace Businesses, as well as legacy defined benefit pension plans assigned to the Company as a result of the Separation. As a result, beginning in the first quarter of 2020 for these U.S. plans and in the second quarter of 2020 for these non-U.S. plans, Arconic applied defined benefit plan accounting resulting in benefit plan expense being recorded in operating income (service cost) and nonoperating income (nonservice cost). In all historical periods prior to these respective timeframes, Arconic was considered a participating employer in ParentCo’s defined benefit plans and, therefore, applied multiemployer plan accounting resulting in the Company’s share of benefit plan expense being recorded entirely in operating income. Also, Arconic is the plan sponsor of certain other non-U.S. defined benefit plans that contain participants related only to the Arconic Businesses and, therefore, the related benefit plan expense was recorded in accordance with defined benefit plan accounting in all periods presented. The following table presents the total benefit plan expense (excluding settlements and curtailments) recorded by Arconic based on the foregoing in each period presented:

allocation of ParentCo’s corporate expenses, including research and development expenses, for the portion of the period prior to the Separation Date (see the Cost Allocations section of The Separation under Overview above).
(3)Metal price lag represents the financial impact of the timing difference between when aluminum prices included in Sales are recognized and when aluminum purchase prices included in Cost of goods sold are realized. This adjustment aims to remove the effect of the volatility in metal prices and the calculation of this impact considers applicable metal hedging transactions.
(4)In 2021 and 2020, Restructuring and other charges includes a $584 and $199, respectively, charge for the settlement of certain employee retirement benefits virtually all of which were within the United States and the United Kingdom. See Note H to the Consolidated Financial Statements in Part II Item 8 of this Form 10-K for additional information.
(5)Other includes certain items that impact Cost of goods sold and Selling, general administrative, and other expenses on the Company’s Statement of Consolidated Operations that are not included in Segment Adjusted EBITDA.
Environmental Matters
See the Environmental Matters section of Note T to the Consolidated Financial Statements in Part II Item 8 of this Form 10-K.
Liquidity and Capital Resources
Arconic’s primary future cash needs are centered on operating activities, including working capital, as well as recurring and strategic capital expenditures. The Company’s ability to fund its cash needs depends on its ongoing ability to generate and raise cash in the future. Although management believes that Arconic’s future cash from operations, together with the Company’s access to capital markets, will provide adequate resources to fund Arconic’s operating and investing needs, the Company’s access to, and the availability of, financing on acceptable terms in the future will be affected by many factors, including: (i) Arconic’s credit rating; (ii) the liquidity of the overall capital markets; and (iii) the current state of the economy. There can be no assurances that the Company will continue to have access to capital markets on terms acceptable to Arconic.
For all periods prior to the Separation Date, ParentCo provided capital, cash management, and other treasury services to the Company. Only cash amounts specifically attributable to Arconic were reflected in the Company’s Consolidated Financial Statements. Transfers of cash, both to and from ParentCo’s centralized cash management system, were reflected as a component of Parent Company net investment in Arconic’s Consolidated Financial Statements.
Cash provided from operations and financing activities is expected to be adequate to cover the Company’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, 2021, the Company’s Cash and cash equivalents were $335, of which $199 was held outside the United States. Of this, approximately $79, or 24%, of total cash and cash equivalents at December 31, 2021 was held in Russia. Cash and cash equivalents held in Russia represented 7% of Arconic’s total liquidity at December 31, 2021. Cash and cash equivalents held in Russia are currently subject to injunctions imposed by regulatory authorities that prohibit the distribution of dividends. We cannot at this time reasonably estimate the likelihood or timeline of a resolution involving the removal of these injunctions, and accordingly cannot reasonably estimate when, if at all, the funds will be available for the payment of dividends to Arconic Corporation. We maintain a renewable intercompany loan facility that could be utilized but we have as yet not utilized this facility. In addition, Arconic has a number of commitments and obligations related to the Company’s operations in various foreign jurisdictions, resulting in the need for cash outside the United States. Management continuously evaluates the Company’s local and global cash needs for future business operations, which may influence future repatriation decisions.
The discussion and analysis that follows includes a comparison of Arconic’s cash flows between the 2021 and 2020 annual periods. Please refer to the Liquidity and Capital Resources section included in Management’s Discussion and Analysis of Financial Condition and Results of Operations in Part II Item 7 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 (filed on February 23, 2021) for a discussion and analysis of Arconic’s cash flows between the 2020 and 2019 annual periods.
Operating Activities
Cash used for operations was $407 in 2021 compared with cash provided from operations of $6 in 2020.
In 2021, cash used for operations was comprised of an unfavorable change in working capital of $505, pension contributions of $458 (see below), and a net loss of $397, partially offset by a positive add-back for non-cash transactions in
51

TABLE OF CONTENTS
earnings of $953. The impact in working capital was largely driven by higher volumes and higher aluminum prices due to an increase in both the average LME price and regional premiums.
In January 2021, the Company contributed a total of $200 to its two funded U.S. defined benefit pension plans, comprised of the estimated minimum required funding for 2021 of $183 and an additional $17.
In April 2021, the Company contributed a total of $250 to its two funded U.S. defined benefit pension plans to maintain the funding level of the remaining plan obligations not transferred under a group annuity contract (see U.S. Pension Plan Annuitizations in Note H to the Consolidated Financial Statements in Part II Item 8 of this Form 10-K for additional information). This contribution was funded with the net proceeds from a March 2021 debt offering (see 2021 Debt Activity in Financing Activities below).
Also in April 2021, the Company received $9 as one of two installments related to a settlement agreement reached with a customer in March 2021. See Sales under Results of Operations above for additional information.
In 2020, cash provided from operations was comprised primarily of a positive add-back for non-cash transactions in earnings of $552 and a favorable change in noncurrent assets and liabilities of $56, mostly offset by pension contributions of $271, an unfavorable change in working capital of $222 (see below), and a net loss of $109.
Cash provided from operations for 2020 includes an unfavorable adjustment of $235 related to the change in the Company’s customer and other receivables balances as of December 31, 2020 ($759) and 2019 ($520). The unfavorable adjustment (i.e., increase in receivables) was derived by calculating the difference in the receivables balances as of December 31, 2020 and 2019 after excluding the effects of divestitures and foreign currency translation. The $235 was negatively impacted by the fact that customer receivables related to the Arconic Corporation Businesses were no longer included in ParentCo’s accounts receivable securitization program effective January 2, 2020. In periods prior to 2020, certain identified customer receivables related to the Arconic Corporation Businesses were sold on a revolving basis to a ParentCo subsidiary under this program and were considered to be effectively and immediately settled for cash. As of December 31, 2019, the amount of Arconic’s outstanding customer receivables sold to ParentCo’s subsidiary was $281. As a result, the Company’s customer receivables balance as of December 31, 2019 reflects the settlement of the $281 even though the third-party customers had not yet paid their obligations to ParentCo, as Arconic no longer had the right to collect and receive cash from the related customers. Had customer receivables related to the Arconic Corporation Businesses not been included in ParentCo’s program in 2019, the Company’s customer receivables balance as of December 31, 2019 would have been higher by $281. Further, these outstanding receivables would have been collected by the Arconic Corporation Businesses from the third-party customers in 2020. Accordingly, the previously mentioned unfavorable change in working capital of $222 would have been a favorable change in working capital of $59. See Cash Management in Note A to the Consolidated Financial Statements in Part II Item 8 of this Form 10-K.
Financing Activities
Cash provided from financing activities was $135 in 2021 compared with $744 in 2020. The source of cash in 2021 was mostly due to $314 in net proceeds from the issuance of new indebtedness (see 2021 Debt Activity below), somewhat offset by $161 for the repurchase of 4,912,505 shares of the Company’s common stock (see Share Repurchase Program below). In 2020, the source of cash was due to $2,343 in net proceeds (reflects additional debt issuance costs paid from cash on hand) from the issuance of new indebtedness (see 2020 Debt Activity below) and $216 in net cash funding provided by ParentCo prior to the Separation Date, partially offset by $1,100 for the repayment of debt (see 2020 Debt Activity below) and a $728 payment to ParentCo in connection with the Separation (see The Separation above).
2021 Debt Activity—On March 3, 2021, the Company completed a Rule 144A (U.S. Securities Act of 1933, as amended) debt offering for an additional $300 aggregate principal amount of 6.125% Senior Secured Second-Lien Notes due 2028 (the “Additional 2028 Notes”). The Additional 2028 Notes were issued under the indenture governing Arconic’s existing 6.125% Senior Secured Second-Lien Notes due 2028 (see 2020 Debt Activity below). Other than with respect to the date of issuance and issue price, the Additional 2028 Notes are treated as a single series with and have the same terms as the referenced existing notes. The Additional 2028 Notes were sold at 106.25% of par (i.e., a premium) and, after reflecting a discount to the initial purchasers of the Additional 2028 Notes, the Company received $315 in net proceeds from the debt offering. Arconic used the net proceeds of this issuance to fund an annuitization of certain U.S. defined benefit pension plan obligations (see Note H to the Consolidated Financial Statements in Part II Item 8 of this Form 10-K for additional information). The premium ($19) and costs to complete the financing ($5) were deferred and are being amortized to interest expense over the term of the Additional 2028 Notes. The amortization of the premium is reflected as a reduction to interest expense and the amortization of the costs to complete the financing is reflected as an addition to interest expense. Interest on the Additional 2028 Notes is paid semi-annually in February and August, and commenced August 15, 2021.

TABLE OF CONTENTS
2020 Debt Activity—In connection with the capital structure to be established at the time of the Separation, Arconic secured $1,200 in third-party indebtedness. On February 7, 2020, the Company completed a Rule 144A (U.S. Securities Act of 1933, as amended) debt offering for $600 aggregate principal amount of 6.125% Senior Secured Second-Lien Notes due 2028 (the “2028 Notes”). Arconic received $593 in net proceeds from the debt offering reflecting a discount to the initial purchasers of the 2028 Notes. Also, on March 25, 2020, the Company entered into a credit agreement, which provided a $600 Senior Secured First-Lien Term Loan B Facility (variable rate and seven-year term) (the “Term Loan”) and a $1,000 Senior Secured First-Lien Revolving Credit Facility (variable rate and five-year term) (the “Credit Facility”), with a syndicate of lenders and issuers named therein (the “Credit Agreement”). Arconic received $575 in net proceeds from the Term Loan reflecting upfront fees and costs to enter into the financing arrangement.
The Company used a portion of the $1,168 in net proceeds from the aggregate indebtedness to make a $728 payment to ParentCo on April 1, 2020 to fund the transfer of certain net assets from ParentCo to Arconic in connection with the completion of the Separation (see The Separation above). The payment to ParentCo was calculated as the difference between (i) the $1,168 of net proceeds from the aggregate indebtedness and (ii) the difference between a beginning cash balance at the Separation Date of $500, as provided for in the Separation and Distribution Agreement, and the amount of cash held by Arconic Businesses at March 31, 2020 ($60 – the sum of this amount and the aggregate indebtedness in (i) equals the sum of Cash and cash equivalents and Restricted cash on the Company’s Combined Balance Sheet as of March 31, 2020).
On April 2, 2020, Arconic borrowed $500, which was subject to an interest rate equal to the sum of the three-month LIBOR plus a 2.0% applicable margin, under the Credit Facility. This borrowing was a proactive measure taken by the Company to bolster its liquidity and preserve financial flexibility in light of uncertainties resulting from the COVID-19 pandemic.
On May 13, 2020, Arconic executed a refinancing of its existing Credit Agreement in order to provide improved financial flexibility. The Company completed a Rule 144A (U.S. Securities Act of 1933, as amended) debt offering for $700 aggregate principal amount of 6.0% Senior Secured First-Lien Notes due 2025 (the “2025 Notes”). Arconic received $691 in net proceeds from the debt offering reflecting a discount to the initial purchasers of the 2025 Notes. Additionally, the Company entered into a five-year credit agreement with a syndicate of lenders named therein and Deutsche Bank AG New York Branch, as administrative agent (the “ABL Credit Agreement”). The ABL Credit Agreement provides for a senior secured asset-based revolving credit facility in an aggregate principal amount of $800 (the available balance as of December 31, 2021 was $790 – see ABL Credit Agreement in Note Q to the Consolidated Financial Statements in Part II Item 8 of this Form 10-K for additional information), including a letter of credit sub-facility and a swingline loan sub-facility (the “ABL Credit Facility”). In addition, the ABL Credit Facility includes an accordion feature allowing Arconic to request one or more increases to the revolving commitments in an aggregate principal amount up to $350. Also, see Note V to the Consolidated Financial Statements in Part II Item 8 of this Form 10-K for additional information.
The Company used the net proceeds from the new indebtedness, together with cash on hand, to prepay in full the obligations outstanding under both the Term Loan ($600) and Credit Facility ($500) and to terminate in full the commitments under the Credit Agreement.
Descriptions of the 2028 Notes, 2025 Notes, and ABL Credit Agreement are set forth in Note Q to the Consolidated Financial Statements in Part II Item 8 of this Form 10-K.
In connection with the issuance of the 2028 Notes and the execution of the Credit Agreement, the Company paid $42 in discounts to the initial purchasers and/or upfront fees and costs (the “debt issuance costs”), of which $30 was attributable to the Term Loan and the Credit Facility. The debt issuance costs were initially deferred and were being amortized to interest expense over the respective terms of the 2028 Notes, the Term Loan, and the Credit Facility. In connection with the issuance of the 2025 Notes and the execution of the ABL Credit Agreement, Arconic paid $15 in discounts to the initial purchasers and/or upfront fees and costs (the “new debt issuance costs”). As a result of applying both debt modification and debt extinguishment accounting, as appropriate based on the lender mix for each debt instrument, to the debt refinancing, the Company was required to write off $16 of the $30 in debt issuance costs and immediately expense $3 of the $15 in new debt issuance costs. This $19 was reported within the year-to-date Interest expense on Arconic’s Statement of Consolidated Operations. The remaining $14 in debt issuance costs continued to be deferred and the remaining $12 in new debt issuance costs were deferred; both are being amortized to interest expense over the respective terms of the 2025 Notes and the ABL Credit Agreement.
Share Repurchase Program—On May 4, 2021, Arconic announced that its Board of Directors approved a share repurchase program authorizing the Company to repurchase shares of its outstanding common stock up to an aggregate transactional value of $300 over a two-year period expiring April 28, 2023. In 2021, Arconic repurchased 4,912,505 shares of the Company's common stock for $161 under this program. See Note K to the Consolidated Financial Statements in Part II Item 8 of this Form 10-K for additional information.

TABLE OF CONTENTS
Ratings—Arconic’s cost of borrowing and ability to access the capital markets are affected not only by market conditions but also by the ratings assigned to Arconic and its debt by the major credit rating agencies. As of December 31, 2021, the following are the most recent ratings for Arconic and its outstanding debt.
Moody’s Investor Service (Moody’s) has assigned a Ba3 rating to both the Company and the 2028 Notes and a Ba1 rating to the 2025 Notes. Additionally, Moody's has given these ratings a stable outlook.
Standard and Poor’s Global Ratings (S&P) has assigned a BB rating to the Company, a B+ rating to the 2028 Notes, and a BB+ rating to the 2025 Notes. Additionally, S&P has given these ratings a stable outlook.
Fitch Ratings (Fitch) has assigned a BB+ rating to both the Company and the 2028 Notes and a BBB- rating to both the 2025 Notes and the ABL Credit Facility. On September 22, 2021, Fitch revised the rating outlook from negative to stable.
Investing Activities
Cash used for investing activities was $181 in 2021 compared with $38 in 2020.
The use of cash in 2021 reflects capital expenditures of $184, more than half of which was attributable to sustaining spend at the U.S. rolling mills.
The use of cash in 2020 reflects capital expenditures of $163, mostly offset by $98 in net proceeds received from the sales of an extrusions plant in South Korea and a rolling mill in Brazil and additional proceeds of $25 (contingent consideration) received from the 2018 sale of the Texarkana (Texas) rolling mill.
Contractual Obligations and Off-Balance Sheet Arrangements
Contractual Obligations. Arconic is required to make future payments under various contracts, including long-term purchase obligations, lease agreements, and financing arrangements. The Company also has commitments to make contributions to its funded pension plans, provide payments for pension (unfunded) and other postretirement benefit plans, and fund capital projects. As of December 31, 2021, a summary of Arconic’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):

TABLE OF CONTENTS
Obligations for Operating Activities
Raw material purchase obligations consist mostly of aluminum with expiration dates ranging from less than one year to two years. Energy-related purchase obligations consist primarily of electricity and natural gas contracts with expiration dates ranging from one year to ten 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.
Operating leases represent multi-year obligations for certain land and buildings, plant equipment, vehicles, and computer equipment.
Interest related to debt is based on stated interest rates on debt with maturities that extend to 2028 (see the 2021 Debt Activity and 2020 Debt Activity sections of Financing Activities under Liquidity and Capital Resources above).
Pension contributions (funded plans) and pension (unfunded plans) and other postretirement benefit payments are based on actuarial estimates using current assumptions for, among others, discount rates, long-term rate of return on plan assets, rate of compensation increases, and/or health care cost trend rates. It is Arconic’s policy to contribute amounts to funded pension plans sufficient to meet the minimum requirements set forth in applicable country employee benefit and tax regulations, including ERISA for U.S. plans. Management has determined that it is not practicable to present pension contributions (funded plans) and both pension (unfunded plans) and other postretirement benefit payments beyond 2026 and 2031, respectively.
Layoff and other restructuring payments relate virtually all to severance costs.
Uncertain tax positions taken or expected to be taken on an income tax return may result in additional payments to tax authorities. As of December 31, 2021, no interest and penalties were accrued related to such positions. The total amount of uncertain tax positions is included in the “Thereafter” column as Arconic 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
The debt amount in the preceding table represents the principal amounts of all outstanding long-term debt, which have maturities that extend to 2028 (see the 2021 Debt Activity and 2020 Debt Activity sections of Financing Activities under Liquidity and Capital Resources above).
As of December 31, 2021, Arconic had 105,326,885 outstanding shares of common stock. Dividends on common stock are subject to authorization by the Company’s Board of Directors. Arconic did not declare or pay any dividends from April 1, 2020 through December 31, 2021.
In May 2021, Arconic’s Board of Directors authorized a common stock repurchase program under which the Company may purchase shares of its outstanding common stock up to an aggregate transactional value of $300, depending on cash availability, market conditions, and other factors. This program has a predetermined expiration date of April 28, 2023; however, the Company is under no contractual obligation to make such repurchases. Accordingly, amounts have not been included in the preceding table. In 2021, the Company repurchased 4,912,505 shares of its common stock for $161. See the Common Stock section of Note K to the Consolidated Financial Statements in Part II Item 8 of this Form 10-K.
Obligations for Investing Activities
Capital projects in the preceding table only include amounts approved by management as of December 31, 2021. 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 $280 in 2022.
Off-Balance Sheet Arrangements. Arconic Corporation has outstanding bank guarantees, letters of credit, and surety bonds related to outstanding responsibilities and obligations. See the Commitments section of Note T to the Consolidated Financial Statements in Part II Item 8 of this Form 10-K.
Critical Accounting Policies and Estimates
The preparation of Arconic’s Consolidated Financial Statements in accordance with accounting principles generally accepted in the United States of America requires management to make certain estimates based on judgments and assumptions regarding uncertainties that may affect the amounts reported in the Consolidated Financial Statements and disclosed in the Notes to the Consolidated Financial Statements. Areas that require such estimates include the review of properties, plants, and
55

TABLE OF CONTENTS
equipment and goodwill for impairment, and accounting for each of the following: environmental and litigation matters; pension and other postretirement employee benefit obligations; stock-based compensation; and income taxes.
Management uses historical experience and all available information to make these estimates, and actual results may differ from those used to prepare Arconic’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, including the Notes to the Consolidated Financial Statements, provide a meaningful and fair perspective of the Company.
A summary of Arconic’s significant accounting policies is included in Note B to the Consolidated Financial Statements in Part II Item 8 of this Form 10-K. Management believes that the application of these policies on a consistent basis enables Arconic to provide the users of the Consolidated Financial Statements with useful and reliable information about Arconic’s operating results and financial condition.
Prior to the Separation Date, Arconic did not operate as a separate, standalone entity. Arconic’s operations were included in ParentCo’s financial results. Accordingly, for all periods prior to the Separation Date, the Company's Consolidated Financial Statements were prepared from ParentCo’s historical accounting records and were presented on a standalone basis as if the Arconic Corporation Businesses had been conducted independently from ParentCo. Such Consolidated Financial Statements include the historical operations that were considered to comprise the Arconic Corporation Businesses, as well as certain assets and liabilities that were historically held at ParentCo’s corporate level but were specifically identifiable or otherwise attributable to Arconic. The Critical Accounting Policies described below reflect any incremental judgments and assumptions made by management in the preparation of the Company’s Consolidated Financial Statements prior to the Separation Date (see The Separation in Overview above for additional information).
Properties, Plants, and Equipment. Properties, plants, and equipment are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of such assets may not be recoverable. Recoverability of assets is determined by comparing the estimated undiscounted net cash flows of the related operations (asset group) to the carrying value of the associated assets. An impairment loss would be recognized when the carrying value of the assets exceeds the estimated undiscounted net cash flows of the asset group. The amount of the impairment loss to be recorded is calculated as the excess of the carrying value of the assets 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.
Goodwill. Goodwill is not amortized; 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, exit, or realign a business. A significant amount of judgment is involved in determining if an indicator of impairment has occurred. Such indicators may include, among others, 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. The fair value that could be realized in an actual transaction may differ from that used to evaluate goodwill for impairment.
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. Arconic has three reporting units—the Rolled Products segment, the Building and Construction Systems segment, and the Extrusions segment—all of which contained goodwill at the time of the Company’s annual 2021 review of goodwill for impairment. Immediately preceding this review, the carrying value of goodwill for Rolled Products, Building and Construction Systems, and Extrusions was $254, $70, and $65, respectively.
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 a 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.
Arconic 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. Arconic’s policy is that a quantitative impairment test be performed for each reporting unit at least once during every three-year period.
56

TABLE OF CONTENTS
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.
Under the quantitative impairment test, the evaluation of the recoverability of goodwill involves comparing the current fair value of each reporting unit to its carrying value, including goodwill. Arconic 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. Several significant assumptions and estimates are involved in the application of the DCF model to forecast operating cash flows, including sales growth (volumes and pricing), production costs, capital spending, working capital levels, and discount rate. Certain of these assumptions may 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 by management with the assistance of valuation experts. In the event the estimated fair value of a reporting unit per the DCF model is less than the carrying value, Arconic would recognize an impairment charge equal to the excess of the reporting unit’s carrying value over its fair value without exceeding the total amount of goodwill applicable to that reporting unit.
During the 2021 annual review of goodwill for impairment, management proceeded directly to the quantitative impairment test for all three of the Company’s reporting units. The result of this review indicated the estimated fair value for both the Rolled Products and Building and Construction Systems reporting units was substantially in excess of the respective carrying value, resulting in no impairment. Conversely, the estimated fair value for the Extrusions reporting unit was lower than the associated carrying value by an amount greater than the carrying value of the Extrusions reporting unit’s goodwill. Accordingly, Arconic recorded an impairment charge of $65 in the fourth quarter of 2021. As a result, the Extrusions reporting unit no longer contains any goodwill.
The impairment of the Extrusion reporting unit’s goodwill resulted from a combination of market-based factors, including continued delays in aerospace market improvement, the expectation that significant cost inflation will extend beyond 2021 resulting in increasingly limited ability for management to drive margin expansion, and a longer than previously anticipated shift in product mix to lower margin industrial products to replace most of the lost aerospace volume. Further, current market factors also resulted in a 150-basis point increase in the WACC compared to the fourth quarter of 2020. Accordingly, given the factors noted above, the estimated fair value of the Extrusions reporting unit was less than the carrying value resulting in a full impairment of its goodwill.
The annual review in 2020 and 2019 indicated that goodwill was not impaired for any of Arconic’s reporting units and there were no triggering events since that time that necessitated an interim quantitative impairment test for any of the Company’s reporting units. That said, in light of the economic impact of the COVID-19 pandemic (i.e., stock market volatility, customer demand disruption, etc.), the Company did perform periodic qualitative assessments throughout 2020 in which management concluded that no impairment existed and, therefore, no further analysis was required.
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 revenues, 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, which are recognized when probable and as agreements are reached with third parties. The estimates may also include costs related to other potentially responsible parties to the extent that Arconic 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, among others, 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. 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, the matter is disclosed and no liability is recorded. With respect to unasserted claims or assessments, management must first determine the probability 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
57

TABLE OF CONTENTS
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.
Pension and Other Postretirement Benefits. For all periods prior to January 1, 2020 (see below), certain employees attributable to the Arconic Corporation Businesses participated in defined benefit pension and other postretirement benefit plans sponsored by ParentCo (the “Shared Plans”), which also included participants attributable to non-Arconic Corporation Businesses. Arconic accounted for the portion of the Shared Plans related to its employees as multiemployer benefit plans. Accordingly, Arconic did not record an asset or liability to recognize any portion of the funded status of the Shared Plans. However, the related expense recorded by the Company was based primarily on pensionable compensation and estimated interest costs related to participants attributable to the Arconic Corporation Businesses.
Prior to the Separation Date, certain other ParentCo plans that were entirely attributable to employees of the Arconic Corporation Businesses (“Direct Plans”) were accounted for as defined benefit pension and other postretirement benefit plans. Accordingly, the funded and unfunded position of each Direct Plan was recorded in the Consolidated Balance Sheet. Actuarial gains and losses that have not yet been recognized in earnings were recorded in accumulated other comprehensive income, net of taxes, until they were amortized as a component of net periodic benefit cost. The determination of benefit obligations and recognition of expenses related to the Direct Plans is dependent on various assumptions, including discount rates, long-term expected rates of return on plan assets, and future compensation increases. ParentCo’s management developed each assumption using relevant company experience in conjunction with market-related data for each individual location in which such plans exist.
In preparation for the Separation, effective January 1, 2020, certain of the Shared Plans were separated into standalone plans for both Arconic (“New Direct Plans”) and ParentCo (see Note H to the Consolidated Financial Statements in Part II Item 8 of this Form 10-K). Additionally, effective April 1, 2020, certain of the other remaining Shared Plans were assumed by Arconic (“Additional New Direct Plans”) (see Note H to the Consolidated Financial Statements in Part II Item 8 of this Form 10-K). Accordingly, beginning on the respective effective dates, the New Direct Plans and the Additional New Direct Plans are accounted for as defined benefit pension and other postretirement plans. Additionally, the Direct Plans continue to be accounted for as defined benefit pension and other postretirement plans.
The following table summarizes the total expenses (excluding settlements and curtailments) recognized by Arconic related to the pension and other postretirement benefits described above:

|  |  |  | Pension benefits |  | Other postretirement benefits
|  |  |  | December 31, |  | December 31,
Type of Plan |  | Type of Expense |  | 2021 |  | 2020 |  | 2019 |  | 2021 |  | 2020 |  | 2019
Cumulative Direct Plans |  | Net periodic benefit cost* |  | $ | 68 |  |  | $ | 82 |  |  | $ | 5 |  |  | $ | 19 |  |  | $ | 22 |  |  | $ | — |

__________________
* In 2021, 2020, and 2019, net periodic benefit cost for pension benefits was comprised of service cost of $21, $21, and $3, respectively, and non-service cost of $47, $61, and $2, respectively. In 2021 and 2020, net periodic benefit cost for other postretirement benefits was comprised of service cost of $6 and $5, respectively, and non-service cost of $13 and $17, respectively.
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 (compensation increases, health care cost trend rates, retirement age, and mortality).
The interest rate used to discount future estimated liabilities is determined using a Company-specific yield curve model (above-median) developed with the assistance of an external actuary. The cash flows of the 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. The yield curve model parallels the projected plan cash flows, which have a weighted average duration of 13 years, and the underlying cash flows of the bonds included in the model exceed the cash flows needed to satisfy the plan obligations multiple times. If a deep market of high quality corporate bonds does not exist in a country, then the yield on government bonds is used. In 2021, the weighted average discount rate used to determine benefit
58

TABLE OF CONTENTS
obligations for pension plans was 2.76% and for other postretirement benefit plans was 2.90%. The impact on the combined pension and other postretirement benefit liabilities of a change in the weighted average discount rate of 1/4 of 1% would be approximately $100 and either a charge or credit of approximately $1 to pretax 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 (the 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 forward-looking investment returns by asset class. Management incorporates expected future investment returns on current and planned asset allocations using information from various external investment managers and consultants, as well as management’s own judgment. For 2021, management used 4.91% as its weighted-average expected long-term rate of return, which was based on the prevailing and planned strategic asset allocations, as well as estimates of future returns by asset class. For 2022, management anticipates that the weighted-average expected long-term rate of return will be in the range of 5.00% to 6.00%. A change in the assumption for the weighted average expected long-term rate of return on plan assets of 1/4 of 1% would impact pretax earnings by approximately $5 for 2021.
Stock-Based Compensation. For all periods prior to the Separation Date, eligible employees attributable to the Arconic Corporation Businesses participated in ParentCo’s stock-based compensation plan. The compensation expense recorded by Arconic included the expense associated with these employees, as well as the expense associated with an allocation of stock-based compensation expense for ParentCo's corporate employees (see Cost Allocations in The Separation under Overview above). From the Separation Date through December 31, 2020, Arconic recorded stock-based compensation expense for all of the Company's employees eligible to participate in Arconic’s stock-based compensation plan. The following describes the manner in which stock-based compensation expense was initially determined for both Arconic and ParentCo.
Compensation expense for employee equity grants is recognized 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. The fair value of stock options is estimated on the date of grant using a lattice-pricing model. The fair value of performance stock units 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.
In 2021, 2020, and 2019, Arconic recognized stock-based compensation expense of $22 ($17 after-tax), $23 ($18 after-tax), and $38 ($30 after-tax), 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 Arconic’s assets and liabilities and are adjusted for changes in tax rates and tax laws when enacted.
For all periods prior to the Separation Date, the Arconic Corporation Businesses were included in the income tax filings of ParentCo. The provision for income taxes was determined in the same manner described above, but on a on a separate return methodology as if Arconic was a standalone taxpayer filing hypothetical income tax returns where applicable. Any additional accrued tax liability or refund arising as a result of this approach was assumed to be immediately settled with ParentCo as a component of Parent Company net investment. Deferred taxes were also determined in the same manner described above and were reflected in the Consolidated Balance Sheet for net operating losses, credits or other attributes to the extent that such attributes were expected to transfer to Arconic upon the Separation. Any difference from attributes generated in a hypothetical return on a separate return basis was adjusted as a component of Parent Company net investment.
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 Arconic’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 re-measured to reflect changes in underlying tax rates due to law changes and the grant and lapse of tax holidays.
Arconic applies 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) 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.
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 its 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 Arconic Corporation Stockholders
Management’s Report on Financial Statements and Practices
The accompanying Consolidated Financial Statements of Arconic Corporation and its subsidiaries (the “Company”) were prepared by management, which is responsible for their integrity and objectivity, in accordance with accounting principles generally accepted in the United States of America (GAAP) and include amounts that are based on management’s best judgments and estimates. The other financial information included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 is consistent with that in the Consolidated Financial Statements.
Management 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, as defined in Rules 13a-15(f) and 15d-15(f) of the U.S. Securities Exchange Act of 1934 (as amended), for the Company. The 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 GAAP. 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 GAAP, 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.
Management conducted an assessment to evaluate the effectiveness of the Company’s internal control over financial reporting as of December 31, 2021 using the criteria in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, management concluded that the Company maintained effective internal control over financial reporting as of December 31, 2021.
PricewaterhouseCoopers LLP, an independent registered public accounting firm, audited the effectiveness of the Company’s internal control over financial reporting as of December 31, 2021, as stated in their report, which is included herein.

To the Board of Directors and Stockholders of Arconic Corporation
Opinions on the Financial Statements and Internal Control over Financial Reporting
We have audited the accompanying consolidated balance sheet of Arconic Corporation and its subsidiaries (the “Company”) as of December 31, 2021 and 2020, 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, 2021, 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, 2021, 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, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021 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, 2021, 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.

TABLE OF CONTENTS
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.
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 Assessment – Extrusions Reporting Unit
As described in Notes B and O to the consolidated financial statements, the Company’s consolidated goodwill balance was $322 million as of December 31, 2021. Goodwill 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, exit, or realign a business. The Company 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. During the current year’s annual review of goodwill, management proceeded directly to the quantitative impairment test for all three of the Company's reporting units. 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. Management recognized an impairment charge of $65 million for the Extrusions reporting unit based on the result of the annual review of goodwill for impairment for the year ended December 31, 2021. Management uses a discounted cash flow model to estimate the current fair value of the reporting units when testing for impairment. Several significant assumptions and estimates are involved in the application of the discounted cash flow model to forecast operating cash flows, including sales growth (volumes and pricing), production costs, capital spending, working capital levels, and discount rate.
The principal considerations for our determination that performing procedures relating to the goodwill impairment assessment of the Extrusions reporting unit is a critical audit matter are the significant judgment by management when developing the fair value 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 significant assumptions related to sales growth (volumes and pricing), production costs, capital spending, and discount rate. Also, 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 Extrusions reporting unit. These procedures also included, among others (i) testing management’s process for developing the fair value estimate of the Extrusions reporting unit; (ii) evaluating the appropriateness of the discounted cash flow model; (iii) testing the completeness, accuracy, and relevance of underlying data used in the model; and (iv) evaluating the reasonableness of the significant assumptions used by management related to sales growth (volumes and pricing), production costs, capital spending, and discount rate. Evaluating management’s assumptions related to sales growth (volumes and pricing) production costs, and capital spending involved evaluating whether the assumptions used by management were reasonable considering (i) the current and past performance of the reporting unit; (ii) the consistency with available industry or market data, executed customer contracts, and approved capital spending budgets; and (iii) 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 Company’s discounted cash flow model and the discount rate assumption.

Arconic Corporation and subsidiaries
Notes to the Consolidated Financial Statements
(dollars in millions, except per-share amounts)
A. The Separation and Basis of Presentation
Arconic Corporation (“Arconic” or the “Company”) is a manufacturer of fabricated aluminum products, including sheet and plate, extrusions, and architectural products and systems, with a primary focus on the ground transportation, aerospace, building and construction, industrial products, and packaging end markets. The Company has 21 primary operating locations in 8 countries around the world, situated in the United States, Canada, China, France, Germany, Hungary, Russia, and the United Kingdom.
References in these Notes to (i) “ParentCo” refer to Arconic Inc., a Delaware corporation, and its consolidated subsidiaries (through March 31, 2020, at which time it was renamed Howmet Aerospace Inc.), and (ii) “2016 Separation Transaction” refer to the November 1, 2016 separation of Alcoa Inc., a Pennsylvania corporation, into two standalone, publicly-traded companies, Arconic Inc. and Alcoa Corporation.
Coronavirus. Our operations and financial results have been, and may continue to be, adversely affected by the coronavirus (COVID-19) pandemic. As a result of the COVID-19 pandemic, several of our automotive and aerospace customers temporarily suspended operations at different points throughout 2020. While many of our customers have resumed operations as it relates to the COVID-19 pandemic, we are unable to estimate with certainty at this time the status, frequency, or duration of any potential reoccurrences of customer shutdowns, or the duration or extent of resumed operations. Due to the impacts of the COVID-19 pandemic on our customers, we are experiencing, and expect to continue experiencing, lower demand and volume for our products. These trends may lead to charges, impairments, and other adverse financial impacts over time, including but not limited to the recoverability of goodwill and long-lived assets and the realizability of deferred tax assets. The impact on our business, results of operations, financial condition, liquidity, and/or cash flows will be magnified if the disruption from the COVID-19 pandemic continues for an extended period.
As a result, Arconic implemented several measures starting in April 2020 to mitigate the impacts of the COVID-19 pandemic on the Company’s business, results of operations, financial condition, liquidity, and cash flows:
•deferred initiating a dividend on common stock;
•reduced the CEO’s salary and the Board of Directors’ cash compensation by 30% (see below);
•reduced salaries for senior-level management by 20% and for all other salaried employees by 10% (see below);
•restructuring of the salaried workforce, reduction of 10%;
•idling of various production facilities based on market conditions within the regions where the Company operates;
•decreasing production and operating with a reduced labor force through shortened work weeks, shift reductions, layoffs, and the elimination of temporary workers and contractors at U.S.-based rolling and extrusion facilities;
•implementing a combination of modified schedules, adjusted work hours, lower costs, and/or delayed raises at all rolling mill facilities in Europe, China, and Russia;
•suspended the 401(k) match program for U.S. salaried employees (see below); and
•reducing capital expenditures by approximately $50, or approximately 30%.
Effective September 1, 2020, the Company restored both the salaries of all salaried employees and the 401(k) match of all salaried U.S. employees, including executive officers, to the levels in effect prior to the actions described above. Also effective September 1, 2020, the Company restored the annual cash retainers payable to the non-employee members of the Company’s Board of Directors to the levels in effect prior to the previous reduction described above.
The Separation. On February 8, 2019, ParentCo announced that its Board of Directors approved a plan to separate into two standalone, publicly-traded companies (the “Separation”). The spin-off company, later named Arconic Corporation, was to include the rolled aluminum products, aluminum extrusions, and architectural products operations of ParentCo, as well as the Latin America extrusions operations sold in April 2018, (collectively, the “Arconic Corporation Businesses”). The existing publicly traded company, ParentCo, was to continue to own the engine products, engineered structures, fastening systems, and forged wheels operations (collectively, the “Howmet Aerospace Businesses”).
The Separation was subject to a number of conditions, including, but not limited to: final approval by ParentCo’s Board of Directors (see below); receipt of an opinion of legal counsel (received on March 31, 2020) regarding the qualification of the distribution, together with certain related transactions, as a “reorganization” within the meaning of Sections 335 and 368(a)(1)(D) of the U.S. Internal Revenue Code (i.e., a transaction that is generally tax-free for U.S. federal income tax purposes); and the U.S. Securities and Exchange Commission (the “SEC”) declaring effective a Registration Statement on Form 10, as amended, filed with the SEC on February 13, 2020 (effectiveness was declared by the SEC on February 13, 2020).

TABLE OF CONTENTS
On February 5, 2020, ParentCo’s Board of Directors approved the completion of the Separation by means of a pro rata distribution by ParentCo of all of the outstanding shares of common stock of Arconic to ParentCo common stockholders of record as of the close of business on March 19, 2020 (the “Record Date”). At the time of the Separation, ParentCo common stockholders were to receive one share of Arconic common stock for every four shares of ParentCo common stock (the “Separation Ratio”) held as of the Record Date (ParentCo common stockholders were to receive cash in lieu of fractional shares).
In connection with the Separation, as of March 31, 2020, Arconic and Howmet Aerospace entered into several agreements to implement the legal and structural separation between the two companies; govern the relationship between Arconic and Howmet Aerospace after the completion of the Separation; and allocate between Arconic and Howmet Aerospace various assets, liabilities, and obligations, including, among other things, employee benefits, environmental liabilities, intellectual property, and tax-related assets and liabilities. These agreements included a Separation and Distribution Agreement, Tax Matters Agreement, Employee Matters Agreement, and certain Patent, Know-How, Trade Secret License and Trademark License Agreements. The Separation and Distribution Agreement identified the assets to be transferred, the liabilities to be assumed, and the contracts to be transferred to each of Arconic and Howmet Aerospace as part of the Separation, and provided for when and how these transfers and assumptions were to occur.
On April 1, 2020 (the “Separation Date”), the Separation was completed and became effective at 12:01 a.m. Eastern Daylight Time. To effect the Separation, ParentCo undertook a series of transactions to separate the net assets and certain legal entities of ParentCo, resulting in a cash payment of $728 to ParentCo by Arconic from a portion of the aggregate net proceeds of previously executed financing arrangements (see Note Q). In connection with the Separation, 109,021,376 shares of Arconic common stock were distributed to ParentCo stockholders. This was determined by applying the Separation Ratio to the 436,085,504 shares of ParentCo’s outstanding common stock as of the Record Date. “Regular-way” trading of Arconic’s common stock began with the opening of the New York Stock Exchange on April 1, 2020 under the ticker symbol “ARNC.” Arconic’s common stock has a par value of $0.01 per share.
ParentCo incurred costs to evaluate, plan, and execute the Separation, and Arconic was allocated a pro rata portion of these costs based on segment revenue (see Cost Allocations below). ParentCo recognized $38 from January 2020 through March 2020 and $78 in 2019 for such costs, of which $18 and $40, respectively, was allocated to Arconic. The allocated amounts were included in Selling, general administrative, and other expenses on the accompanying Statement of Consolidated Operations.
Basis of Presentation. The Consolidated Financial Statements of Arconic are prepared in conformity with accounting principles generally accepted in the United States of America (GAAP). In accordance with GAAP, certain situations require management to make estimates based on judgments and assumptions, which 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 revenues and expenses during the reporting periods. Actual results could differ from those estimates upon subsequent resolution of identified matters. These estimates are based on historical experience and, in some cases, assumptions based on current and future market experience, including considerations related to the COVID-19 pandemic. Management has made its best estimates using all relevant information available at the time, but it is possible that these estimates will differ from actual results and affect the Consolidated Financial Statements in future periods and potentially require adverse adjustments to the recoverability of goodwill and long-lived assets, the realizability of deferred tax assets and other judgments and estimations and assumptions that may be impacted by the COVID-19 pandemic.
Principles of Consolidation. The Consolidated Financial Statements of Arconic include the accounts of Arconic and companies in which Arconic has a controlling interest. Intercompany transactions have been eliminated.
Management evaluates whether an Arconic entity or interest is a variable interest entity and whether Arconic is the primary beneficiary. Consolidation is required if both of these criteria are met. Arconic does not have any variable interest entities requiring consolidation.
Prior to the Separation Date, Arconic did not operate as a separate, standalone entity. Arconic’s operations were included in ParentCo’s financial results. Accordingly, for all periods prior to the Separation Date, the accompanying Consolidated Financial Statements were prepared from ParentCo’s historical accounting records and were presented on a standalone basis as if the Arconic Corporation Businesses had been conducted independently from ParentCo. Such Consolidated Financial Statements include the historical operations that were considered to comprise the Arconic Corporation Businesses, as well as certain assets and liabilities that were historically held at ParentCo’s corporate level but were specifically identifiable or otherwise attributable to Arconic. ParentCo’s net investment in these operations was reflected as Parent Company net investment on the accompanying Consolidated Financial Statements. All significant transactions and accounts within Arconic were eliminated. All significant intercompany transactions between ParentCo and Arconic were included within Parent Company net investment on the accompanying Consolidated Financial Statements.

TABLE OF CONTENTS
Cost Allocations. The description and information on cost allocations is applicable for all periods included in the Consolidated Financial Statements prior to the Separation Date.
The Consolidated Financial Statements of Arconic include general corporate expenses of ParentCo that were not historically charged to the Arconic Corporation Businesses for certain support functions that were provided on a centralized basis, such as expenses related to finance, audit, legal, information technology, human resources, communications, compliance, facilities, employee benefits and compensation, and research and development activities. These general corporate expenses were included on the accompanying Statement of Consolidated Operations within Cost of goods sold, Selling, general administrative and other expenses, and Research and development expenses. These expenses were allocated to Arconic on the basis of direct usage when identifiable, with the remainder allocated based on the Arconic Corporation Businesses’ segment revenue as a percentage of ParentCo’s total segment revenue, as reported in the respective periods.
All external debt not directly attributable to Arconic was excluded from the accompanying Consolidated Balance Sheet. Financing costs related to these debt obligations were allocated to Arconic based on the ratio of capital invested by ParentCo in the Arconic Corporation Businesses to the total capital invested by ParentCo in both the Arconic Corporation Businesses and the Howmet Aerospace Businesses, and were included on the accompanying Statement of Consolidated Operations within Interest expense.
The following table reflects the allocations described above:

|  | 2020 |  | 2019
Cost of goods sold(1) |  | $ | — |  |  | $ | 14 |
Selling, general administrative, and other expenses(2) |  | 25 |  |  | 115 |
Research and development expenses |  | — |  |  | 11 |
Provision for depreciation and amortization |  | 1 |  |  | 10 |
Restructuring and other charges (E) |  | 2 |  |  | 7 |
Interest expense (F) |  | 28 |  |  | 115 |
Other (income), net |  | (5) |  |  | (6) |

_________________
(1)For all periods presented, amount principally relates to an allocation of expenses for ParentCo’s retained pension and other postretirement benefit obligations associated with closed and sold operations.
(2)In 2020 (January through March) and 2019, amount includes an allocation of $18 and $40, respectively, for costs incurred by ParentCo associated with the Separation (see above).
Management believes the assumptions regarding the allocation of ParentCo’s general corporate expenses and financing costs were reasonable.
Nevertheless, the Consolidated Financial Statements of Arconic may not include all of the actual expenses that would have been incurred and may not reflect Arconic’s consolidated results of operations, financial position, and cash flows had it been a standalone company during the periods prior to the Separation Date. Actual costs that would have been incurred if Arconic had been a standalone company would depend on multiple factors, including organizational structure, capital structure, and strategic decisions made in various areas, including information technology and infrastructure. Transactions between Arconic and ParentCo, including sales to the Howmet Aerospace Businesses, were presented as related party transactions in these Consolidated Financial Statements and were considered to be effectively settled for cash at the time the transaction was recorded. The total net effect of the settlement of these transactions was reflected on the accompanying Statement of Consolidated Cash Flows as a financing activity and on the accompanying Consolidated Balance Sheet as Parent Company net investment.
Cash Management. The description and information on cash management is applicable for all periods included in the Consolidated Financial Statements prior to the Separation Date.
Cash was managed centrally with certain net earnings reinvested locally and working capital requirements met from existing liquid funds. Accordingly, the cash and cash equivalents held by ParentCo at the corporate level were not attributed to Arconic for any of the periods presented prior to the Separation Date. Only cash amounts specifically attributable to Arconic were reflected in the accompanying Consolidated Balance Sheet. Transfers of cash, both to and from ParentCo’s centralized cash management system, were reflected as a component of Parent Company net investment on the accompanying Consolidated Balance Sheet and as a financing activity on the accompanying Statement of Consolidated Cash Flows.

TABLE OF CONTENTS
ParentCo had an arrangement with several financial institutions to sell certain customer receivables without recourse on a revolving basis. The sale of such receivables was completed through the use of a bankruptcy-remote special-purpose entity, which was a consolidated subsidiary of ParentCo. In connection with this arrangement, in all periods prior to January 1, 2020, certain of Arconic’s customer receivables were sold on a revolving basis to this bankruptcy-remote subsidiary of ParentCo; these sales were reflected as a component of Parent Company net investment on Arconic’s Consolidated Balance Sheet. As of December 31, 2019, the amount of Arconic’s outstanding customer receivables sold to ParentCo’s subsidiary was $281. Effective January 2, 2020, in preparation for the Separation, ParentCo’s arrangement was amended to no longer include customer receivables associated with the Arconic Corporation Businesses, as well as to remove previously included customer receivables related to the Arconic Corporation Businesses not yet collected as of January 2, 2020. Accordingly, uncollected customer receivables of $281 related to the Arconic Corporation Businesses were removed from the program and the right to collect and receive the cash from the customer was returned to Arconic.
ParentCo participated in several accounts payable settlement arrangements with certain vendors and third-party intermediaries. These arrangements provided that, at the vendor’s request, the third-party intermediary advance the amount of the scheduled payment to the vendor, less an appropriate discount, before the scheduled payment date and ParentCo make payment to the third-party intermediary on the date stipulated in accordance with the commercial terms negotiated with its vendors. In connection with these arrangements, certain of Arconic’s accounts payable were settled, at the vendor’s request, before the scheduled payment date; these settlements were reflected as a component of Parent Company net investment on Arconic’s Consolidated Balance Sheet. As of December 31, 2019, the amount of Arconic’s accounts payables settled under such arrangements that had yet to be extinguished between ParentCo and third-party intermediaries was $1.
B. Summary of Significant Accounting Policies
Cash Equivalents. Cash equivalents are highly liquid investments purchased with an original maturity of three months or less. For all periods prior to the Separation Date, the cash and cash equivalents held by ParentCo at the corporate level were not attributed to Arconic. Only cash amounts specifically attributable to Arconic were reflected on the Company's Consolidated Financial Statements.
Inventory Valuation. Inventories are carried at the lower of cost and net realizable value, with cost for most inventories determined under the average cost method. The cost of certain non-U.S. inventories is determined under the first in, first out (FIFO) method.
Properties, Plants, and Equipment. Properties, plants, and equipment are recorded at cost. Also, interest related to the construction of qualifying assets is capitalized as part of the construction costs. Depreciation is recorded 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
Rolled Products | 33 |  | 22
Building and Construction Systems | 25 |  | 18
Extrusions | 32 |  | 20

Repairs and maintenance are charged to expense as incurred. Generally, gains or losses from the sale of asset groups are recorded in Restructuring and other charges while gains and losses from the sale of individual assets are recorded in Other expenses (income), net.
Properties, plants, and equipment are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of such assets may not be recoverable. Recoverability of assets is determined by comparing the estimated undiscounted net cash flows of the related operations (asset group) to the carrying value of the associated assets. An impairment loss would be recognized when the carrying value of the assets exceeds the estimated undiscounted net cash flows of the asset group. The amount of the impairment loss to be recorded is calculated as the excess of the carrying value of the assets 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.
Goodwill. Goodwill is not amortized; 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, exit, or realign a business. A significant amount of judgment is involved in determining if an indicator of impairment has occurred. Such indicators may include, among others, deterioration in
72

TABLE OF CONTENTS
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. The fair value that could be realized in an actual transaction may differ from that used to evaluate goodwill for impairment.
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. Arconic has three reporting units—the Rolled Products segment, the Building and Construction Systems segment, and the Extrusions segment—all of which contained goodwill at the time of the Company’s annual 2021 review of goodwill for impairment. Immediately preceding this review, the carrying value of goodwill for Rolled Products, Building and Construction Systems, and Extrusions was $254, $70, and $65, respectively.
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 a 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.
Arconic 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. Arconic’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.
Under the quantitative impairment test, the evaluation of the recoverability of goodwill involves comparing the current fair value of each reporting unit to its carrying value, including goodwill. Arconic 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. Several significant assumptions and estimates are involved in the application of the DCF model to forecast operating cash flows, including sales growth (volumes and pricing), production costs, capital spending, working capital levels, and discount rate. Certain of these assumptions may 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 by management with the assistance of valuation experts. In the event the estimated fair value of a reporting unit per the DCF model is less than the carrying value, Arconic would recognize an impairment charge equal to the excess of the reporting unit’s carrying value over its fair value without exceeding the total amount of goodwill applicable to that reporting unit.
During the 2021 annual review of goodwill for impairment, management proceeded directly to the quantitative impairment test for all three of the Company’s reporting units. The result of this review indicated the estimated fair value for both the Rolled Products and Building and Construction Systems reporting units was substantially in excess of the respective carrying value, resulting in no impairment. Conversely, the estimated fair value for the Extrusions reporting unit was lower than the associated carrying value by an amount greater than the carrying value of the Extrusions reporting unit’s goodwill. Accordingly, Arconic recorded an impairment charge of $65 in the fourth quarter of 2021. As a result, the Extrusions reporting unit no longer contains any goodwill.
The impairment of the Extrusion reporting unit’s goodwill resulted from a combination of market-based factors, including continued delays in aerospace market improvement, the expectation that significant cost inflation will extend beyond 2021 resulting in increasingly limited ability for management to drive margin expansion, and a longer than previously anticipated shift in product mix to lower margin industrial products to replace most of the lost aerospace volume. Further, current market factors also resulted in a 150-basis point increase in the WACC compared to the fourth quarter of 2020. Accordingly, given the factors noted above, the estimated fair value of the Extrusions reporting unit was less than the carrying value resulting in a full impairment of its goodwill.
73

TABLE OF CONTENTS
The annual review in 2020 and 2019 indicated that goodwill was not impaired for any of Arconic’s reporting units and there were no triggering events since that time that necessitated an interim quantitative impairment test for any of the Company’s reporting units. That said, in light of the economic impact of the COVID-19 pandemic (i.e., stock market volatility, customer demand disruption, etc.), the Company did perform periodic qualitative assessments throughout 2020 in which management concluded that no impairment existed and, therefore, no further analysis was required.
Other Intangible Assets. Intangible assets with finite useful lives are amortized on a straight-line basis over the periods benefited. The following table details the weighted-average useful lives of software and other intangible assets by reporting segment (numbers in years):

| Software |  | Other intangible assets
Rolled Products | 7 |  | 15
Building and Construction Systems | 4 |  | 20
Extrusions | 4 |  | 10

Leases. Arconic determines whether a contract contains a lease at inception. The Company leases certain 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. Arconic includes renewal option periods in the lease term when it is determined that the options are reasonably certain to be exercised. Certain of the Company’s real estate lease agreements include rental payments that either have fixed contractual increases over time or adjust periodically for inflation. Also, 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.
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 calculated at the lease commencement date and are recognized as lease expense on a straight-line basis over the lease term. Arconic 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 the Company’s leases do not provide an implicit rate. The operating lease right-of-use assets also include any lease prepayments made and are 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 revenues, 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, which are recognized when probable and as agreements are reached with third parties. The estimates may also include costs related to other potentially responsible parties to the extent that Arconic 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, among others, 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. 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, the matter is disclosed and no liability is recorded. With respect to unasserted claims or assessments, management must first determine the probability 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. Arconic’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 customer contracts 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. Arconic produces aluminum sheet and
74

TABLE OF CONTENTS
plate; extruded and machined parts; integrated aluminum architectural systems; and architectural extrusions. Transfer of control is assessed based on alternative use of the products produced and Arconic’s 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 product, the country of origin, and the type of transportation (truck, train, or vessel).
In certain circumstances, Arconic 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 on the Consolidated Balance Sheet.
Pension and Other Postretirement Benefits. For all periods prior to January 1, 2020 (see below), certain employees attributable to the Arconic Corporation Businesses participated in defined benefit pension and other postretirement benefit plans sponsored by ParentCo (the “Shared Plans”), which also included participants attributable to non-Arconic Corporation Businesses. Arconic accounted for the portion of the Shared Plans related to its employees as multiemployer benefit plans. Accordingly, Arconic did not record an asset or liability to recognize any portion of the funded status of the Shared Plans. However, the related expense recorded by the Company was based primarily on pensionable compensation and estimated interest costs related to participants attributable to the Arconic Corporation Businesses.
Prior to the Separation Date, certain other ParentCo plans that were entirely attributable to employees of the Arconic Corporation Businesses (“Direct Plans”) were accounted for as defined benefit pension and other postretirement benefit plans. Accordingly, the funded and unfunded position of each Direct Plan was recorded in the Consolidated Balance Sheet. Actuarial gains and losses that have not yet been recognized in earnings were recorded in accumulated other comprehensive income, net of taxes, until they were amortized as a component of net periodic benefit cost. The determination of benefit obligations and recognition of expenses related to the Direct Plans is dependent on various assumptions, including discount rates, long-term expected rates of return on plan assets, and future compensation increases. ParentCo’s management developed each assumption using relevant company experience in conjunction with market-related data for each individual location in which such plans exist.
In preparation for the Separation, effective January 1, 2020, certain of the Shared Plans were separated into standalone plans for both Arconic (“New Direct Plans”) and ParentCo (see Note H). Additionally, effective April 1, 2020, certain of the other remaining Shared Plans were assumed by Arconic (“Additional New Direct Plans”) (See Note H). Accordingly, beginning on the respective effective dates, the New Direct Plans and the Additional New Direct Plans are accounted for as defined benefit pension and other postretirement plans. Additionally, the Direct Plans continue to be accounted for as defined benefit pension and other postretirement plans.
Stock-Based Compensation. For all periods prior to the Separation Date, eligible employees attributable to the Arconic Corporation Businesses participated in ParentCo’s stock-based compensation plan. The compensation expense recorded by Arconic included the expense associated with these employees, as well as the expense associated with an allocation of stock-based compensation expense for ParentCo’s corporate employees (see Cost Allocations in Note A). For all periods after the Separation Date, Arconic recorded stock-based compensation expense for all of the Company's employees eligible to participate in Arconic’s stock-based compensation plan. The following describes the manner in which stock-based compensation expense was initially determined for both Arconic and ParentCo.
Compensation expense for employee equity grants is recognized 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. The fair value of stock options is estimated on the date of grant using a lattice-pricing model. The fair value of performance stock units 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.
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 Arconic’s assets and liabilities and are adjusted for changes in tax rates and tax laws when enacted.

TABLE OF CONTENTS
For all periods prior to the Separation Date, the Arconic Corporation Businesses were included in the income tax filings of ParentCo. The provision for income taxes was determined in the same manner described above, but on a on a separate return methodology as if Arconic was a standalone taxpayer filing hypothetical income tax returns where applicable. Any additional accrued tax liability or refund arising as a result of this approach was assumed to be immediately settled with ParentCo as a component of Parent Company net investment. Deferred taxes were also determined in the same manner described above and were reflected in the Consolidated Balance Sheet for net operating losses, credits or other attributes to the extent that such attributes were expected to transfer to Arconic upon the Separation. Any difference from attributes generated in a hypothetical return on a separate return basis was adjusted as a component of Parent Company net investment.
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 Arconic’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 re-measured to reflect changes in underlying tax rates due to law changes and the grant and lapse of tax holidays.
Arconic applies 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) 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.
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 its 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.
Foreign Currency. The local currency is the functional currency for Arconic’s significant operations outside the United States, except for operations in Russia, where the U.S. dollar is used as the functional currency. The determination of the functional currency for Arconic’s operations is made based on the appropriate economic and management indicators.
Recently Adopted Accounting Guidance. On January 1, 2021, Arconic adopted changes issued by the Financial Accounting Standards Board (FASB) to accounting for income taxes. The FASB issued this guidance to simplify various aspects related to the accounting for income taxes as part of the overall initiative to reduce complexity in accounting standards. These changes include the removal of certain exceptions and the simplification of several provisions, including: requiring an entity to recognize tax that is partially based on income, such as franchise tax, as income-based tax and account for additional amounts incurred as non-income based tax; requiring an entity to evaluate when a step up in tax basis of goodwill should be considered part of the original business combination or a separate transaction; and requiring an entity to reflect the effect of an enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date. The adoption of this guidance did not have a material impact on the Consolidated Financial Statements. The Company will need to continue to consider this guidance in future periods.
On January 1, 2020, Arconic adopted changes issued by the Financial Accounting Standards Board (FASB) to credit losses. This guidance added a new impairment model (known as the current expected credit loss (CECL) model), which is based on expected losses rather than incurred losses. Under this model, an entity is required to recognize an allowance equivalent to 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. This model does not have a minimum threshold for recognition of impairment losses and requires the measurement of expected credit losses on assets that have a low risk of loss. The adoption of this guidance did not have a material impact on the Consolidated Financial Statements. This guidance will need to be considered in future assessments of credit losses.

TABLE OF CONTENTS
Effective December 31, 2020, Arconic adopted changes issued by the FASB that modify disclosures for defined benefit pension plans and other postretirement benefit plans. These modifications consist of the elimination, addition, and clarification of several disclosures aimed at improving the effectiveness of such disclosure. Changes that impact Arconic’s disclosure include the following: (i) elimination of presenting the amounts in accumulated other comprehensive income expected to be recognized (i.e., amortization of net actuarial losses and prior service costs) as non-service components of net periodic benefit cost over the next fiscal year; (ii) for postretirement health care benefits, elimination of the effects of a one-percentage point change in assumed health care cost trend rates on the (a) aggregate of the service and interest cost components of net periodic benefit cost and (b) benefit obligation; and (iii) addition of an explanation of the reasons for significant gains and losses related to the changes in benefit obligations for the reporting period. The remaining changes under this guidance either do not represent a change to the Company’s previous disclosures or are not applicable. Other than applying the disclosure changes (see Note H), the adoption of this guidance did not have an impact on the Consolidated Financial Statements.
On January 1, 2019, Arconic adopted changes issued by the FASB to the accounting and presentation of leases. These changes require lessees to recognize a right-of-use asset and lease liability on the balance sheet, initially measured at the present value of the future lease payments for all operating leases with a term greater than 12 months. These changes were 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 measured and recognized on the Consolidated Balance Sheet. 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 allowed, among other things, 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 guidance resulted in the Company recording operating lease right-of-use assets and lease liabilities of $150 on the Consolidated Balance Sheet as of January 1, 2019. Also, the Company reclassified a net $73 to Parent Company net investment comprised of  $119 from Other noncurrent liabilities and deferred credits, $24 from Properties, plants, and equipment, net, and $22 from Deferred income tax assets reflecting the cumulative effect of an accounting change related to the sale-leaseback of Arconic’s Texarkana (Texas) cast house (see Note S). The adoption of the standard had no impact on the Statement of Consolidated Operations or Statement of Consolidated Cash Flows. See Note P for disclosures related to the Company’s operating leases.
Recently Issued Accounting Guidance. In March 2020, the FASB issued guidance that provides optional expedients and exceptions for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. These expedients and exceptions may be used when applying GAAP, if certain criteria are met, to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of such reform. The purpose of this guidance is to provide relief to entities from experiencing unintended accounting and/or financial reporting outcomes or consequences due to reference rate reform. This guidance became effective immediately on March 12, 2020 and may be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2022, after which time the expedients and exceptions expire. In January 2021, the FASB issued clarifying guidance to specify that certain of the optional expedients and exceptions apply to derivatives that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform. This additional guidance may be applied on a full retrospective basis as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively in the manner previously described for the guidance issued on March 12, 2020. As of December 31, 2021, Arconic has not experienced any unintended outcomes or consequences of reference rate reform that would necessitate the adoption of this guidance. Additionally, the Company will not need to consider the application of this guidance related to its credit agreement, which is scheduled to mature on May 13, 2025 and provides a credit facility that is referenced to LIBOR in certain borrowing situations, as the terms of such agreement currently provide for a replacement rate if LIBOR is discontinued by the end of 2021 as expected. That said, management will continue to closely monitor all potential instances of reference rate reform to determine if adoption of this guidance becomes necessary in the future.

D. Segment and Related Information
Segment Information
Arconic has three operating and reportable segments, which are organized by product on a global basis: Rolled Products, Building and Construction Systems, and Extrusions (see segment descriptions below). The Company determined the chief operating decision maker to be the CEO, who regularly reviews the financial information of these three segments to assess performance and allocate resources.
Arconic’s profit or loss measure for its reportable segments is Segment Adjusted EBITDA (Earnings before interest, taxes, depreciation, and amortization). The Company calculates Segment Adjusted EBITDA as Total sales (third-party and intersegment) minus each of (i) Cost of goods sold, (ii) Selling, general administrative, and other expenses, and (iii) Research and development expenses, plus Stock-based compensation expense and Metal price lag. Arconic’s Segment Adjusted EBITDA may not be comparable to similarly titled measures of other companies’ reportable segments.
Segment assets are comprised of customer receivables; inventories; properties, plants, and equipment, net; and goodwill.
The accounting policies of the segments are the same as those described in the Summary of Significant Accounting Policies (see Note B). Transactions among segments are established based on negotiation among the parties.
78

TABLE OF CONTENTS
The following are detailed descriptions of Arconic’s reportable segments:
Rolled Products. This segment produces aluminum sheet and plate for a variety of end markets. Sheet and plate are sold directly to customers and through distributors related to the aerospace, ground transportation, packaging, building and construction, and industrial products (mainly used in the production of machinery and equipment and consumer durables) end markets. A small portion of this segment also produced aseptic foil for the packaging end market prior to February 1, 2020 (see Note S). While the customer base for flat-rolled products is large, a significant amount of sales of sheet and plate is to a relatively small number of customers. Prices for these products are generally based on the price of metal plus a premium for adding value to the aluminum to produce a semi-finished product, resulting in a business model in which the underlying price of metal is contractually passed-through to customers. Our subsidiaries that own and operate our facility located in Samara, Russia are, and have been since the Separation, subject to proceedings initiated by Russian regulatory authorities (see Note T).
Building and Construction Systems. This segment manufactures products that are used primarily in the non-residential building and construction end market. These products include integrated aluminum architectural systems and architectural extrusions, which are sold directly to customers and through distributors.
Extrusions. This segment produces a range of extruded and machined parts for the aerospace, ground transportation, and industrial products end markets. These products are sold directly to customers and through distributors. Prices for these products are generally based on the price of metal plus a premium for adding value to the aluminum to produce a semi-finished product, resulting in a business model in which the underlying price of metal is contractually passed-through to customers.
The operating results and assets of Arconic’s reportable segments were as follows (differences between segment totals and Arconic’s consolidated totals for line items not reconciled are in Corporate):

TABLE OF CONTENTS
(1)In preparation for the Separation, effective January 1, 2020, certain U.S. defined benefit pension and other postretirement plans previously sponsored by ParentCo were separated into standalone plans for both Arconic and Howmet Aerospace. Additionally, effective April 1, 2020, Arconic assumed a portion of the obligations associated with certain non-U.S. defined benefit pension plans that included participants related to both the Arconic Businesses and the Howmet Aerospace Businesses, as well as legacy defined benefit pension plans assigned to the Company as a result of the Separation. As a result, beginning in the first quarter of 2020 for these U.S. plans and in the second quarter of 2020 for these non-U.S. plans, Arconic applied defined benefit plan accounting resulting in benefit plan expense being recorded in operating income (service cost) and nonoperating income (nonservice cost). In all historical periods prior to these respective timeframes, Arconic was considered a participating employer in ParentCo’s defined benefit plans and, therefore, applied multiemployer plan accounting resulting in the Company’s share of benefit plan expense being recorded entirely in operating income. Also, Arconic is the plan sponsor of certain other non-U.S. defined benefit plans that contain participants related only to the Arconic Businesses and, therefore, the related benefit plan expense was recorded in accordance with defined benefit plan accounting in all periods presented. The following table presents the total benefit plan expense (excluding settlements and curtailments) recorded by Arconic based on the foregoing in each period presented:

(2)Corporate expenses are composed of general administrative and other expenses of operating the corporate headquarters and other global administrative facilities. The amounts presented for all periods prior to second quarter 2020 include an allocation of ParentCo’s corporate expenses, including research and development expenses, for the portion of the period prior to the Separation Date (see Cost Allocations in Note A).
(3)Metal price lag represents the financial impact of the timing difference between when aluminum prices included in Sales are recognized and when aluminum purchase prices included in Cost of goods sold are realized. This adjustment aims to remove the effect of the volatility in metal prices and the calculation of this impact considers applicable metal hedging transactions.
(4)In 2021 and 2020, Restructuring and other charges include a $584 and $199, respectively, charge for the settlement of certain employee retirement benefits virtually all of which were within the United States and the United Kingdom (see Note H).
(5)Other includes certain items that impact Cost of goods sold and Selling, general administrative, and other expenses on the Company’s Statement of Consolidated Operations that are not included in Segment Adjusted EBITDA.

In 2021, the total number of employees to be separated was updated to 500 from 550 to reflect employees initially identified for separation accepting other positions within the Company and natural attrition. As of December 31, 2021, the employee separations associated with 2020 restructuring programs were essentially complete. In 2021 and 2020, the Company made cash payments of $5 and $15, respectively, against layoff reserves related to the 2020 restructuring programs.

TABLE OF CONTENTS
In 2020, the total number of employees to be separated was updated to 370 from 480 to reflect the reversal of a program initiated by ParentCo in 2019, natural attrition, and employees initially identified for separation accepting other positions within the Company. As of September 30, 2021, the employee separations associated with 2019 restructuring programs were essentially complete. In 2021, 2020, and 2019, the Company made cash payments of $3, $9, and $11, respectively, against layoff reserves related to the 2019 restructuring programs.

In 2020, Other, net includes a $20 benefit for the reversal of a liability previously established at the Separation Date related to a potential indemnification to Howmet Aerospace by Arconic for an outstanding income tax matter in Spain. Under the terms of the Tax Matters Agreement (see Note A) related to the Separation, Arconic was responsible for 34% of the potential loss related to this matter should Howmet Aerospace receive an unfavorable ruling from Spain’s Supreme Court. At the time of Separation, Arconic management believed that the likelihood of the Company performing under the indemnification was probable resulting in a liability being established on Arconic’s opening balance sheet at the Separation Date. In November 2020, a favorable ruling was received from Spain’s Supreme Court bringing a final conclusion to this matter as this decision may not be appealed any further. As no further income tax payment was required of Howmet Aerospace likewise Arconic no longer has a requirement to perform under the indemnification.
H. Pension and Other Postretirement Benefits
Defined Benefit Plans
Arconic sponsors several defined benefit pension and other postretirement plans covering eligible employees and retirees in U.S. and foreign locations, as well as certain legacy plans previously sponsored by ParentCo. Prior to January 1, 2020 for U.S. plans and prior to April 1, 2020 for certain non-U.S. plans, eligible employees and retirees related to the Arconic Businesses participated in ParentCo-sponsored defined benefit pension and other postretirement plans (the “Shared Plans”), which included participants related to the Howmet Aerospace Businesses and ParentCo corporate participants, as well as eligible retirees from previously closed or sold operations. Also, prior to the Separation Date, other eligible employees and retirees related to the Arconic Businesses participated in certain non-U.S. defined benefit pension and other postretirement plans (the “Direct Plans”).
The Company accounted for the portion of the Shared Plans related to its employees as multiemployer benefit plans. Accordingly, Arconic did not record an asset or liability to recognize the funded status of the Shared Plans. However, the related pension and other postretirement benefit expenses attributable to Arconic were based primarily on pensionable compensation of active Arconic participants and estimated interest costs, respectively. The Company also recorded an allocation of pension and other postretirement benefit expenses for the Shared Plans attributable to ParentCo corporate participants, as well as to participants related to closed and sold operations (see Cost Allocations in Note A).
The Direct Plans were accounted for as defined benefit pension and other postretirement plans. Accordingly, the funded status of each Direct Plan was recorded in the Company’s Consolidated Balance Sheet. Actuarial gains and losses that had not yet been recognized in earnings were recorded in Accumulated other comprehensive loss until they were amortized as a component of net periodic benefit cost. The determination of benefit obligations and recognition of expenses related to Direct Plans were dependent on various assumptions, including discount rates, long-term expected rates of return on plan assets, and future compensation increases. Management developed each assumption using relevant company experience in conjunction with market-related data for each of the plans.
In preparation for the Separation, effective January 1, 2020, certain U.S. pension and other postretirement benefit plans previously sponsored by ParentCo (the “U.S. Shared Plans” – see above) were separated into standalone plans for both Arconic (the “New Direct Plans”) and Howmet Aerospace. Accordingly, on January 1, 2020, Arconic recognized an aggregate liability of $1,920, of which $60 was current, reflecting the combined net unfunded status of the New Direct Plans, comprised of a benefit obligation of $4,255 and plan assets of $2,335, as well as $1,752 (net of tax impact) in Accumulated other comprehensive loss representing a net actuarial loss.
Additionally, effective on the Separation Date, certain other Shared Plans (the “Additional New Direct Plans,” and, collectively with the Direct Plans and New Direct Plans, the “Cumulative Direct Plans”) were assumed by Arconic. Accordingly, on April 1, 2020, Arconic recognized a noncurrent asset of $65 and a noncurrent liability of $15, reflecting the
85

TABLE OF CONTENTS
combined net funded status of the Additional New Direct Plans, as well as $50 (net of tax impact) in Accumulated other comprehensive loss representing a net actuarial loss.
U.S. Pension Plan Annuitizations—In April 2021, Arconic purchased a group annuity contract to transfer the obligation to pay the remaining retirement benefits of approximately 8,400 participants in two U.S. defined benefit pension plans to an insurance company. In connection with this transaction, the Company contributed a total of $250 to the two plans to maintain the funding level of the remaining plan obligations not transferred. This contribution was funded with the net proceeds from a March 2021 debt offering (see 2021 Activity in Note Q). Prior to this action, these two plans had an aggregate of approximately 23,000 participants.
This transaction represents a significant settlement event, and, as a result, the Company was required to complete a remeasurement of these two plans (generally completed on an annual basis as of December 31, 2020), including an interim actuarial valuation of the plan obligations. Accordingly, the weighted-average discount rate used in calculating the plan obligations increased to 3.10% as of April 30, 2021 from 2.54% as of December 31, 2020. The remeasurement resulted in a combined projected benefit obligation and fair value of plan assets of $3,337 and $2,790, respectively, as of April 30, 2021. From these amounts, the group annuity transaction resulted in the settlement of $995 in plan obligations and the transfer of $1,007 in plan assets. The remeasurement of these two plans, together with the annuitization, resulted in a $152 net decrease to Accrued pension benefits and a $117 (after-tax) net decrease to Accumulated other comprehensive loss (see Note L). Additionally, the annuitization resulted in the accelerated amortization of a portion of the existing net actuarial loss associated with these two plans in the amount of $549 ($423 after-tax). This amount was reclassified to earnings through Restructuring and other charges (see Note E) from Accumulated other comprehensive loss (see Note L).
In December 2020, Arconic purchased a group annuity contract to transfer the obligation to pay the remaining retirement benefits of approximately 7,000 participants from two U.S. defined benefit pension plans to an insurance company. On a combined basis, this transaction resulted in the settlement of approximately $240 in plan obligations and the transfer of approximately $245 in plan assets. Prior to this action, these two plans had approximately 30,000 participants combined. The Company recognized a $140 ($108 after-tax) settlement charge, which represents the accelerated amortization of a portion of the existing net actuarial loss associated with these plans. This amount was reclassified to earnings through Restructuring and other charges (see Note E) from Accumulated other comprehensive loss (see Note L).
U.S. OPEB Plan Amendments—In August 2021, Arconic modified the medical benefit coverage offered to certain Medicare-eligible participants under the Company's U.S. other postretirement benefit plan. Effective January 1, 2022, this modification results in lower premiums and increased benefits to the participants. This change qualifies as a significant plan amendment to the Company's U.S. other postretirement benefit plan. Accordingly, this plan was required to be remeasured, and through this process, the discount rate was updated to 2.78% at August 31, 2021 from 2.61% at December 31, 2020. The amendment, together with the remeasurement of this plan, resulted in a $34 net decrease to the Company's other postretirement benefits liability and a $26 (after-tax) net decrease to Accumulated other comprehensive loss (see Note L) on the accompanying Consolidated Balance Sheet. The impact of this change on the Company's annual net periodic benefit cost is not material. The Company's estimated annual benefit payments will decrease by approximately $4 beginning in 2022.
In July 2020, Arconic and the United Steelworkers agreed to modify the medical benefit coverage offered to certain Medicare-eligible participants under the Company's U.S. other postretirement benefit plan, as provided for in the current master collective bargaining agreement between the parties. Effective January 1, 2021, this modification results in lower premiums and increased benefits to the participants. This change qualifies as a significant plan amendment to the Company's U.S. other postretirement benefit plan. Accordingly, this plan was required to be remeasured, and through this process, the discount rate was updated to 2.54% at July 31, 2020 from 3.17% at December 31, 2019. The amendment, together with the remeasurement of this plan, resulted in a net decrease to both the Company's other postretirement benefits liability of $7 and Accumulated other comprehensive loss of $5 (after-tax). The impact of this change on the Company's annual net periodic benefit cost is not material. The Company's estimated annual benefit payments decreased by approximately $20 beginning in 2021.
U.K. Pension Plan Annuitization—In June 2020, Arconic and Howmet Aerospace, together, executed several liability management actions related to approximately 1,800 participants in a U.K. defined benefit pension plan. The primary action was the purchase of a group annuity contract to transfer the obligation to pay the remaining retirement benefits of certain plan participants to an insurance company. On a combined basis, these actions resulted in the settlement of approximately $400 in plan obligations and the transfer of approximately $460 in plan assets. In the 2020 second quarter, the Company contributed $10 to the plan to facilitate these actions and maintain the funding level of the remaining plan obligations. Prior to these actions, this plan had approximately 3,350 participants combined.
Accordingly, this plan was required to be remeasured, and through this process, the discount rate was updated to 1.55% at June 30, 2020 from 2.05% at December 31, 2019. The settlement events, together with the remeasurement of the plan, resulted
86

TABLE OF CONTENTS
in an approximately $250 net reduction to the Company’s remaining plan obligation and both a decrease to the Company’s pension benefit asset and a settlement charge of $58 ($48 after-tax) in 2020. The settlement charge represents the accelerated amortization of a portion of the existing net actuarial loss associated with this plan. This amount was reclassified to earnings through Restructuring and other charges (see Note E) from Accumulated other comprehensive loss. Subsequent to this remeasurement, the remaining respective plan obligations and plan assets attributable to Arconic and Howmet Aerospace were transferred into separate plans and the existing U.K. plan was terminated. Immediately following the completion of the transfer, the Company’s remaining plan obligation was approximately $240 and the plan assets were approximately $260 related to 1,050 plan participants.
The following table summarizes the total expenses (excluding settlements and curtailments) recognized by Arconic related to the pension and other postretirement benefits described above:

(1)In 2021 and 2020, net periodic benefit cost for U.S pension plans was $653 and $220, respectively.
(2)In 2021, Settlements were due to the purchase of a group annuity contract ($549 - see U.S. Pension Plan Annuitizations above) and the payment of lump-sum benefits ($35). In 2020, Settlements were due to two separate purchases of a group annuity contract (see U.S. Pension Plan Annuitizations and U.K. Pension Plan Annuitization above).
(3)Service cost was included within Cost of goods sold, Settlements were included within Restructuring and other charges, and all other components were included in Other expenses (income), net on the accompanying Statement of Consolidated Operations.

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

| Benefit obligations |  | Net periodic benefit cost
| December 31, |  | For the year ended December 31,
| 2021 |  | 2020 |  | 2021 |  | 2020 |  | 2019
Discount rate—pension plans | 2.76 | % |  | 2.45 | % |  | 2.27 | % |  | 2.86 | % |  | 3.12 | %
Discount rate—other postretirement benefit plans | 2.90 |  |  | 2.61 |  |  | 2.19 |  |  | 2.49 |  |  | *
Rate of compensation increase—pension plans | 2.66 |  |  | 2.55 |  |  | 2.54 |  |  | 3.20 |  |  | 3.42 |
Expected long-term rate of return on plan assets—pension plans | — |  |  | — |  |  | 4.91 |  |  | 6.09 |  |  | 6.73 |

______________________
*In 2019 the Company's other postretirement benefit plans were not material.
The discount rate is determined using a Company-specific yield curve model (above-median) developed with the assistance of an external actuary. The cash flows of the 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. The yield curve model parallels the projected plan cash flows, which have a weighted average duration of 13 years, and the underlying cash flows of the bonds included in the model exceed the cash flows needed to satisfy the plan obligations multiple times. If a deep market of high quality corporate bonds does not exist in a country, then the yield on government bonds is used.
The expected long-term rate of return on plan assets is generally applied to a five-year market-related value of plan assets (the 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 forward-looking investment returns by asset class. Management incorporates expected future investment returns on current and planned asset allocations using information from various external investment managers and consultants, as well as management’s own judgment. For 2021 and 2020, the 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. For 2022, management anticipates that the weighted-average expected long-term rate of return will be in the range of 5.00% to 6.00%.
Weighted-average assumed health care cost trend rates for U.S. other postretirement benefit plans were as follows (non-U.S. plans are not material):

|  | 2021 |  | 2020
Health care cost trend rate assumed for next year |  | 4.5 | % |  | 7.7 | %
Rate to which the cost trend rate gradually declines |  | 4.7 | % |  | 4.6 | %
Year that the rate reaches the rate at which it is assumed to remain |  | 2027 |  | 2026

The assumed health care cost trend rate is used to measure the expected cost of gross eligible charges covered by the Company’s other postretirement benefit plans. For 2022, a 4.5% trend rate will be used, reflecting management’s best estimate of the change in future health care costs covered by the plans.

TABLE OF CONTENTS
Plan Assets
Arconic’s pension plan investment policy and weighted average asset allocations at December 31, 2021 and 2020, by asset class, were as follows:

|  |  |  | Plan assets at December 31,
Asset class |  | Policy maximum |  | 2021 |  | 2020
Equities |  | 40% |  | 31 | % |  | 20 | %
Fixed income |  | 100% |  | 56 |  |  | 51 |
Other investments |  | 30% |  | 13 |  |  | 29 |
Total |  |  |  | 100 | % |  | 100 | %

The principal objectives underlying the investment of the pension plan assets are to ensure that Arconic 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. The use of derivative instruments is permitted where appropriate and necessary for achieving diversification across the balance of the asset portfolio. Investment practices comply with the requirements of applicable country laws and regulations.
The following section describes the valuation methodologies used by the trustees to measure the fair value of pension plan assets. For plan assets measured at net asset value, this refers to the net asset value of the investment on a per share basis (or its equivalent) as a practical expedient. Otherwise, an indication of the level in the fair value hierarchy in which each type of asset is generally classified is provided (see Note U 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 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 net asset value; and (iii) direct investments in long/short equity hedge funds and private equity (limited partnerships and venture capital partnerships) and are valued at net asset value.
Fixed income—These securities consist of: (i) U.S. government debt and are generally valued using quoted prices (included in Level 1); and (ii) 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).
Other investments—These investments include, among others: (i) real estate investment trusts valued based on the closing price reported in an active market on which the investments are traded (included in Level 1); (ii) the plans’ share of commingled funds that are invested in real estate partnerships and are valued at net asset value; (iii) direct investments in discretionary and systematic macro hedge funds and private real estate (includes limited partnerships) and are valued at net asset value; and (iv) absolute return strategy funds 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 Arconic 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.

Funding and Cash Flows
It is Arconic’s policy to contribute amounts to funded defined benefit pension plans sufficient to meet the minimum requirements set forth in applicable country employee benefit and tax regulations, including ERISA for U.S. plans. From time to time, Arconic may contribute additional amounts as deemed appropriate. In 2021 and 2020, cash contributions to Arconic’s funded defined benefit pension plans were $458 and $271, respectively. The 2021 cash contributions include a total of $250 made by the Company in April 2021 to its two funded U.S. defined benefit pension plans to maintain the funding level of the remaining plan obligations not transferred under a group annuity contract (see U.S. Pension Plan Annuitizations above). The minimum required contributions to Arconic’s funded defined benefit pension plans in 2022 are estimated to be $32, of which $22 is for U.S. plans. Benefit payments expected to be paid to pension (funded and unfunded) and other postretirement benefit plan participants are as follows:

For the year ended December 31, |  | Pension benefits |  | Other postretirement benefits
2022 |  | $ | 164 |  |  | $ | 29 |
2023 |  | 162 |  | 28
2024 |  | 160 |  | 27
2025 |  | 158 |  | 27

2027 through 2031 |  | 763 |  | 128
|  | $ | 1,565 |  |  | $ | 266 |

Defined Contribution Plans
Arconic sponsors savings and investment plans in the United States and certain other countries. Prior to the Separation Date, employees attributable to the Arconic Businesses participated in ParentCo-sponsored plans. In the United States, employees may contribute a portion of their compensation to the plans, and Arconic (ParentCo prior to the Separation Date) matches a specified percentage of these contributions in equivalent form of the investments elected by the employee. Also, Arconic (ParentCo prior to the Separation Date) makes contributions to a retirement savings account based on a percentage of eligible compensation for certain U.S. employees. Arconic’s expenses (contributions) related to all defined contribution plans were $39 in 2021, $35 in 2020, and $38 in 2019.

(1)Deferred tax assets with no expiration may still have annual limitations on utilization.
(2)Employee benefits will become deductible for tax purposes over an extended period of time as contributions are made to employee benefit plans and payments are made to participants. Other represents deferred tax assets whose expiration is dependent upon the reversal of the underlying temporary difference.
The total deferred tax asset (net of valuation allowance) is supported by projections of future taxable income exclusive of reversing temporary differences (65%) and taxable temporary differences that reverse within the carryforward period (35%).

(1)This line item reflects valuation allowances initially established as a result of a change in management’s judgement regarding the realizability of deferred tax assets.
(2)This line item reflects movements in previously established valuation allowances, which increase or decrease as the related deferred tax assets increase or decrease. Such movements occur as a result of remeasurement due to a tax rate change and changes in the underlying attributes of the deferred tax assets, including expiration of the attribute and reversal of the temporary difference that gave rise to the deferred tax assets.
Undistributed net earnings. Foreign undistributed net earnings that have not otherwise previously been subject to U.S. tax are generally exempt from U.S. tax if repatriated in the future. Such future distributions, as well as distributions of previously taxed foreign earnings, may be subject to U.S. state and/or foreign withholding taxes in certain jurisdictions. Also, foreign currency gains/losses related to the translation of previously taxed foreign earnings from the functional currency to the U.S. dollar may be subject to U.S. tax if such earnings were to be distributed in the future. At this time, Management has no plans to repatriate such earnings in the foreseeable future, as the Company has several commitments and obligations related to its operations in various foreign jurisdictions. Management continuously evaluates the Company’s local and global cash needs for future business operations and anticipated debt facilities, which may influence future repatriation decisions. If such earnings were to be distributed in the future, management does not expect the potential U.S. state and/or foreign withholding taxes to be material to the Company’s Consolidated Financial Statements.
Uncertain tax positions. Arconic and its subsidiaries file income tax returns in various U.S. federal, U.S. state, and foreign jurisdictions. For U.S. federal income tax purposes, Arconic’s U.S. operations were included in the income tax filings of ParentCo’s U.S. consolidated tax group through March 31, 2020. ParentCo’s U.S. federal income tax filings have been examined for all periods through 2020. In 2021, the Company’s U.S. consolidated tax group filed a nine-month (April 1, 2020 through December 31, 2020) U.S. federal income tax return which is subject to income tax examination. For U.S. state and foreign income tax purposes, Arconic and its subsidiaries remain subject to income tax examinations for the 2014 tax year and forward.
A reconciliation of the beginning and ending amount of unrecognized tax benefits (excluding interest and penalties) was as follows:

December 31, |  | 2021 |  | 2020 |  | 2019
Balance at beginning of year |  | $ | 23 |  |  | $ | 21 |  |  | $ | 18 |
Additions for tax positions of prior years |  | 1 |  |  | — |  |  | 4 |
Foreign currency translation |  | (2) |  |  | 2 |  |  | (1) |
Balance at end of year |  | $ | 22 |  |  | $ | 23 |  |  | $ | 21 |

Unrecognized tax benefits, if recognized, would not impact the annual effective tax rate for 2021, 2020, and 2019. Management does not anticipate that changes in the Company's unrecognized tax benefits will have a material impact on the Statement of Consolidated Operations during 2022.
It is Arconic’s policy to recognize interest and penalties related to income taxes as a component of the Benefit (Provision) for income taxes on the accompanying Statement of Consolidated Operations. In 2021, 2020, and 2019, Arconic did not recognize any interest or penalties. As of December 31, 2021 and 2020, no interest and penalties were accrued.

TABLE OF CONTENTS
J. Earnings Per Share
Basic earnings per share (EPS) amounts are computed by dividing Net (loss) income attributable to Arconic by the weighted-average number of common shares outstanding. Diluted EPS amounts assume the issuance of common stock for all potentially dilutive share equivalents outstanding. Specific to Arconic, such share equivalents consist of outstanding employee stock awards (excluding out-of-the-money stock options – see below). For periods in which the Company generates net income, the diluted weighted-average number of shares include common share equivalents associated with outstanding employee stock awards. For periods in which the Company generates a net loss, common share equivalents are excluded from the diluted weighted-average number of shares as their effect is anti-dilutive.
The share information used to compute basic and diluted EPS attributable to Arconic common stockholders was as follows (shares in millions):

|  | 2021 |  | 2020 |  | 2019
Weighted-average shares outstanding – basic |  | 109 |  | 109 |  | 109

________________
* Stock options are in-the-money when the respective exercise price of each such option is less than the average market price of the Company’s common stock during the applicable period presented. Conversely, stock options are out-of-the-money when the respective exercise price of each such option is more than the average market price of the Company’s common stock during the applicable period presented. Out-of-the-money stock options never result in common share equivalents for purposes of diluted EPS regardless of whether a company generates net income or a net loss. As of December 31, 2020 there were 0.5 million out-of-the money stock options outstanding with a weighted average exercise price of $33.32.
Prior to the Separation Date, Arconic did not have any publicly-traded issued and outstanding common stock or any common share equivalents. Accordingly, in 2019 the EPS included on the accompanying Statement of Consolidated Operations was calculated based on the 109,021,376 shares of Arconic common stock distributed on the Separation Date in connection with the completion of the Separation (see Note A).
K. Preferred and Common Stock
Preferred Stock. Arconic is authorized to issue 10,000,000 shares of preferred stock at a par value of $0.01 per share. At December 31, 2021 and 2020, the Company had no issued preferred stock.
Common Stock. Arconic is authorized to issue 150,000,000 shares of common stock at a par value of $0.01 per share. On April 1, 2020, in connection with the Separation, the Company distributed 109,021,376 shares of its common stock to ParentCo’s stockholders (see Note A). As of December 31, 2021 and 2020, Arconic had 110,239,390 and 109,205,226, respectively, issued and 105,326,885 and 109,205,226, respectively, outstanding shares of common stock. In 2021 and from April 1, 2020 through December 31, 2020, the Company issued 1,034,164 and 183,850, respectively, shares of common stock under its employee stock-based compensation plan (see below).

TABLE OF CONTENTS
On May 4, 2021, Arconic announced that its Board of Directors approved a share repurchase program authorizing the Company to repurchase shares of its outstanding common stock up to an aggregate transactional value of $300 over a two-year period expiring April 28, 2023. Repurchases under the program may be made from time to time, as the Company deems appropriate, solely through open market repurchases effected through a broker dealer, based on a variety of factors such as price, capital position, liquidity, financial performance, alternative uses of capital, and overall market conditions. There can be no assurance as to the number of shares the Company will repurchase. The share repurchase program may be increased or otherwise modified, renewed, suspended or terminated by the Company at any time, without prior notice. This program is intended to comply with Rule 10b5-1 and all purchases shall be made in compliance with Rule 10b-18, including without limitation the timing, price, and volume restrictions thereof. In 2021, Arconic repurchased 4,912,505 shares, of the Company's common stock for $161 under this program.
The Company issues new shares of common stock to satisfy the exercise of stock options and the conversion of stock units granted under its employee stock-based compensation plan. On May 20, 2021, the Company’s shareholders approved an amendment to the plan to increase the shares of common stock authorized for issuance by 3,000,000 to 11,500,000 shares and to eliminate the plan’s fungible share accounting, with the result that shares issued pursuant to full value stock awards, on or after the date of amendment, will be counted against the share reserve as one share issued under each such award, rather than as one and one-half shares. Shares returned to the plan, on or after the date of amendment, will be counted as one share, regardless of whether such shares were counted as one and one-half shares upon grant based on the prior fungible share accounting convention. In 2021 and from April 1, 2020 through December 31, 2020, there were 251,919 and 84,959, respectively, stock options exercised and 1,125,983 and 157,230, respectively, stock units converted (see table below). Additionally, as of December 31, 2021 and 2020, there were 590,906 and 1,026,808, respectively, stock options and 3,913,337 and 4,544,063, respectively, stock units outstanding (i.e., unexercised and/or unvested) under this plan (see table below). Accordingly, as of December 31, 2021 and 2020, there were 4,749,255 and 336,293, respectively, shares of common stock available for issuance under the plan.
Dividends on common stock are subject to authorization by the Company’s Board of Directors. Arconic did not declare any dividends in 2021 and from April 1, 2020 through December 31, 2020.
Stock-based Compensation
For all periods prior to the Separation Date, eligible employees attributable to the Arconic Businesses participated in ParentCo’s stock-based compensation plan. In 2021 and from the Separation Date through December 31, 2020, eligible Arconic employees participated in the Company’s stock-based compensation plan.
Effective April 1, 2020, all outstanding stock options (vested and non-vested) and non-vested stock units originally granted under ParentCo’s stock-based compensation plan related to employees of the Arconic Businesses, as well as the ParentCo corporate employees that became Arconic employees at Separation, were replaced with similar stock options and stock units under Arconic’s stock-based compensation plan. In order to preserve the intrinsic value of these awards, the referenced employees received replacement stock options and stock units under Arconic’s stock-based compensation plan at a ratio of 1.07 and 2.18, respectively, compared to the number of stock options and stock units originally granted under ParentCo’s stock-based compensation plan. The ratio for stock options was developed by dividing the March 31, 2020 closing market price ($16.06) of ParentCo’s common stock by the April 1, 2020 opening market price ($15.00) of Arconic’s common stock (the Company’s common stock did not trade on a “when issued” basis prior to April 1, 2020). Additionally, the exercise price of stock options was decreased by a ratio of 0.93 developed by dividing $15.00 by $16.06. The ratio for stock units was developed by dividing the March 31, 2020 closing market price of ParentCo’s common stock by the volume weighted average trading price ($7.37) of Arconic’s common stock during the first five trading days subsequent to March 31, 2020. This resulted in a beginning balance of outstanding stock options and stock units under Arconic’s stock-based compensation plan of 1,173,492 and 3,062,013, respectively, as of April 1, 2020. The respective fair values of these stock options and units were adjusted accordingly. Arconic did not recognize any immediate incremental stock-based compensation expense as a result of this adjustment.
The following description of Arconic’s stock-based compensation plan is not materially different from the description of ParentCo’s stock-based compensation plan prior to the Separation.
Stock awards are generally granted in the first quarter of each calendar year to eligible employees at the closing market price of Arconic’s common stock on the date of grant. Stock options typically grade-vest over a three-year service period (1/3 each year) with a ten-year contractual term; stock units typically cliff-vest on the third anniversary of the award grant date. As a condition of Arconic’s stock-based compensation plan design, individuals who are retirement-eligible have a six-month requisite service period in the year of grant.

TABLE OF CONTENTS
In 2021, certain of the stock unit grants also contain both performance and market conditions (the “performance stock units”) and were granted to a limited number of eligible employees, including the Company’s executive officers. The final number of performance stock units earned is dependent on Arconic’s achievement of certain targets (performance condition) and by a total stockholder return (“TSR”) (market condition) over a three-year measurement period. Specifically, determination of the initial number of stock units earned is based on the Company’s achievement of an adjusted EBITDA target (50%), a return on invested capital (25%) and TSR (25%). In 2021, TSR was added as a stand-alone metric rather than a post-performance period multiplier (see below) to further align executive compensation with the creation of shareholder value as compared to Arconic’s peers. For the 2021 performance stock units, cumulative three-year performance goals (including for the TSR) were established for the performance period.
In 2020, certain of the stock unit grants also contain both performance and market conditions (the “performance stock units”) and were granted to a limited number of eligible employees, including the Company’s executive officers. The final number of performance stock units earned is dependent on Arconic’s achievement of certain targets (performance condition) modified by a TSR multiplier (market condition) over a three-year measurement period. Specifically, determination of the initial number of stock units earned is based on the Company’s achievement of an adjusted EBITDA target (25%), a controllable free cash flow target (25%), and a pretax return on net assets target (50%). For the 2020 performance stock units, the Compensation Committee of the Company's Board of Directors established three one-year financial targets to address the lack of visibility and challenge in setting long-term financial goals at the outset of the COVID-19 pandemic, while aligning executive compensation to long-term results. This result is then scaled by the TSR multiplier, which is based on the Company’s relative three-year (January 1 of the grant year through December 31 of the third year in the service period) performance against the TSRs of a group of peer companies. Similar grants were made by ParentCo in 2019 and 2018 but these awards were subsequently converted by ParentCo management prior to 2020 at 100% and 97.5%, respectively, of target to stock units with no such conditions for the remainder of the service period in consideration of the Separation.
In 2021, 2020, and 2019, Arconic recognized stock-based compensation expense of $22 ($17 after-tax), $23 ($18 after-tax), and $38 ($30 after-tax), respectively, of which a minimum of approximately 85% was related to stock units in each period. No stock-based compensation expense was capitalized in 2021, 2020, or 2019. For periods prior to the Separation, the stock-based compensation expense recorded by Arconic was comprised of two components: (i) the expense associated with employees attributable to the Arconic Businesses, and (ii) an allocation of expense related to ParentCo corporate employees (see Cost Allocations in Note A). In 2020 (January through March) and 2019, this allocation was $5 and $30, respectively, of Arconic’s recognized stock-based compensation expense. Also, in 2019, Arconic’s recognized stock-based compensation expense includes a benefit of $2 (through allocation) for certain executive pre-vest stock award cancellations. This benefit was recorded in Restructuring and other charges (see Note E) on the accompanying Statement of Consolidated Operations.
Stock-based compensation expense is based on the grant date fair value of the applicable equity grant. For stock units with no market condition, the fair value is equivalent to the closing market price of Arconic’s or ParentCo’s common stock on the date of grant in the respective periods. For stock units granted with a market condition, the fair value is estimated on the date of grant using a Monte Carlo simulation model, which generated a result of $46.17, $10.02, and $11.93 per unit in 2021, 2020, and 2019 respectively. There were no stock options granted in 2021, 2020, or 2019. As previously mentioned, the estimated fair values for stock units (granted in 2019 and 2018) and stock options (granted in 2018) outstanding at March 31, 2020 were adjusted in order to maintain the intrinsic value of these awards in connection with the Separation.
To estimate the fair value of a stock unit with a market condition, the Monte Carlo simulation model uses certain assumptions, including a risk-free interest rate and volatility, to estimate the probability of satisfying market conditions. The risk-free interest rate (0.3% in 2021, 0.2% in 2020, and 1.6% in 2019) was based on a yield curve of interest rates at the time of the grant based on the remaining performance period. Volatility was estimated using implied and historical volatility (50.1% in 2021, 35.4% in 2020, and 33.4% in 2019).

TABLE OF CONTENTS
The activity for stock options and stock units, including performance stock units granted to the Company's executive officers, from January 1, 2021 through December 31, 2021 was as follows:

|  | Stock options |  | Stock units
|  | Number of options |  | Weighted average exercise price |  | Number of units |  | Weighted average FMV per unit
Outstanding, January 1, 2021 |  | 1,026,808 |  |  | $ | 26.64 |  |  | 4,544,063 |  |  | $ | 10.36 |

Outstanding, December 31, 2021 |  | 590,906 |  |  | 25.56 |  |  | 3,913,337 |  |  | 15.14 |

(1)The number of converted units includes 343,738 shares “withheld” to meet the Company’s statutory tax withholding requirements related to the income earned by the employees as a result of vesting in the units.
(2)In 2021, the Company adjusted the target payout of those performance stock awards granted in 2020. Since the grant date, these awards have been accounted for based on a payout at 100% of target. However, in 2021 the payout for these awards was estimated to be at 8.3% of target. Accordingly, the shares outstanding for these awards from grant date through the date of adjustment were adjusted to reflect the probable payout percentage.
As of December 31, 2021, the 590,906 outstanding stock options had a weighted average remaining contractual life of 2.6 years and a total intrinsic value of $4. Additionally, as of December 31, 2021 all of the total outstanding stock options were fully vested and exercisable. In 2021 and from April 1, 2020 through December 31, 2020, cash received from stock option exercises was $6 and the total intrinsic value of stock options exercised was $2.
At December 31, 2021, there was $15 (pre-tax) of combined unrecognized compensation expense related to non-vested grants of both stock options and stock units. This expense is expected to be recognized over a weighted average period of 2 years.

TABLE OF CONTENTS
P. Leases
Arconic leases certain land and buildings, plant equipment, vehicles, and computer equipment, which have been classified as operating leases. Operating lease cost, which includes short-term leases and variable lease payments and approximates cash paid, was $59, $62, and $63 in 2021, 2020, and 2019, respectively.
Right-of-use assets obtained in exchange for operating lease obligations in 2021 and 2020 were $17 and $46, respectively.
Future minimum contractual operating lease obligations were as follows:

December 31, |  | 2021
2022 |  | 40 |
2023 |  | 30 |
2024 |  | 23 |
2025 |  | 17 |
2026 |  | 12 |
Thereafter |  | 28 |
Total lease payments |  | $ | 150 |
Less: imputed interest |  | 25 |
Present value of lease liabilities |  | $ | 125 |

The weighted-average remaining lease term and weighted-average discount rate for Arconic's operating leases at December 31, 2021 and 2020 was 6.1 and 6.6 years, respectively, and 5.8% and 5.9%, respectively.

|  | $ | 1,594 |  |  | $ | 1,278 |

2021 Activity—On March 3, 2021, the Company completed a Rule 144A (U.S. Securities Act of 1933, as amended) debt offering for an additional $300 aggregate principal amount of 6.125% Senior Secured Second-Lien Notes due 2028 (the “Additional 2028 Notes”). The Additional 2028 Notes were issued under the indenture governing Arconic’s existing 6.125% Senior Secured Second-Lien Notes due 2028 (see 2020 Activity below). Other than with respect to the date of issuance and issue price, the Additional 2028 Notes are treated as a single series with and have the same terms as the referenced existing notes. The Additional 2028 Notes were sold at 106.25% of par (i.e., a premium) and, after reflecting a discount to the initial purchasers of the Additional 2028 Notes, the Company received $315 in net proceeds from the debt offering. Arconic used the net proceeds of this issuance to fund an annuitization of certain U.S. defined benefit pension plan obligations (see Note H). The premium ($19) and costs to complete the financing ($5) were deferred and are being amortized to interest expense over the term of the Additional 2028 Notes. The amortization of the premium is reflected as a reduction to interest expense and the amortization of the costs to complete the financing is reflected as an addition to interest expense. Interest on the Additional 2028 Notes is paid semi-annually in February and August and commenced August 15, 2021.
2020 Activity—In connection with the capital structure to be established at the time of the Separation, Arconic secured $1,200 in third-party indebtedness. On February 7, 2020, Arconic completed a Rule 144A (U.S. Securities Act of 1933, as amended) debt offering for $600 of 6.125% Senior Secured Second-Lien Notes due 2028 (the “2028 Notes”). The Company received $593 in net proceeds from the debt offering reflecting a discount to the initial purchasers of the 2028 Notes. Also, on March 25, 2020, Arconic entered into a credit agreement, which provided a $600 Senior Secured First-Lien Term Loan B Facility (variable rate and seven-year term) (the “Term Loan”) and a $1,000 Senior Secured First-Lien Revolving Credit Facility (variable rate and five-year term) (the “Credit Facility”), with a syndicate of lenders and issuers named therein (the “Credit Agreement”). The Company received $575 in net proceeds from the Term Loan reflecting upfront fees and costs to enter into the financing arrangement.

TABLE OF CONTENTS
The Company used a portion of the $1,168 in net proceeds from the aggregate indebtedness to make a $728 payment to ParentCo on April 1, 2020 to fund the transfer of certain net assets from ParentCo to Arconic in connection with the completion of the Separation (see Note A). The payment to ParentCo was calculated as the difference between (i) the $1,168 of net proceeds from the aggregate indebtedness and (ii) the difference between a beginning cash balance at the Separation Date of $500, as provided for in the Separation and Distribution Agreement, and the amount of cash held by Arconic Businesses at March 31, 2020 ($60 – the sum of this amount and the aggregate indebtedness in (i) equals the sum of Cash and cash equivalents and Restricted cash on the Company’s Combined Balance Sheet as of March 31, 2020).
On April 2, 2020, Arconic borrowed $500, which was subject to an interest rate equal to the sum of the three-month LIBOR plus a 2.0% applicable margin, under the Credit Facility. This borrowing was a proactive measure taken by the Company to bolster its liquidity and preserve financial flexibility in light of uncertainties resulting from the COVID-19 pandemic (see Note A).
On May 13, 2020, Arconic executed a refinancing of its existing Credit Agreement in order to provide improved financial flexibility. Arconic completed a Rule 144A (U.S. Securities Act of 1933, as amended) debt offering for $700 of 6.0% Senior Secured First-Lien Notes due 2025 (the “2025 Notes”). The Company received $691 in net proceeds from the debt offering reflecting a discount to the initial purchasers of the 2025 Notes. Additionally, Arconic entered into a credit agreement with a syndicate of lenders named therein and Deutsche Bank AG New York Branch, as administrative agent (the “ABL Credit Agreement”). The ABL Credit Agreement provides for a senior secured asset-based revolving credit facility in an aggregate principal amount of $800 (see Note V), including a letter of credit sub-facility and a swingline loan sub-facility (the “ABL Credit Facility”). In addition, the ABL Credit Facility includes an accordion feature allowing the Company to request one or more increases to the revolving commitments in an aggregate principal amount up to $350 (see Note V).
Arconic used the net proceeds from the new indebtedness, together with cash on hand, to prepay in full the obligations outstanding under both the Term Loan ($600) and Credit Facility ($500) and to terminate in full the commitments under the Credit Agreement.
Descriptions of the 2028 Notes, 2025 Notes, and ABL Credit Agreement are set forth below.
In connection with the issuance of the 2028 Notes and the execution of the Credit Agreement, the Company paid $42 in discounts to the initial purchasers and/or upfront fees and costs (the “debt issuance costs”), of which $30 was attributable to the Term Loan and the Credit Facility. The debt issuance costs were initially deferred and were being amortized to interest expense over the respective terms of the 2028 Notes, the Term Loan, and the Credit Facility. In connection with the issuance of the 2025 Notes and the execution of the ABL Credit Agreement, the Company paid $15 in discounts to the initial purchasers and/or upfront fees and costs (the “new debt issuance costs”). As a result of applying both debt modification and debt extinguishment accounting, as appropriate based on the lender mix for each debt instrument, to the debt refinancing, the Company was required to write off $16 of the $30 in debt issuance costs and immediately expense $3 of the $15 in new debt issuance costs. This $19 was reported within Interest expense on the Company’s Statement of Consolidated Operations. The remaining $14 in debt issuance costs continued to be deferred and the remaining $12 in new debt issuance costs were deferred; both are being amortized to interest expense over the respective terms of the 2025 Notes and the ABL Credit Agreement.
Separately, in August 2012, ParentCo and the Iowa Finance Authority entered into a loan agreement for the proceeds from the issuance of $250 in Midwestern Disaster Area Revenue Bonds Series 2012 due 2042 (the “Bonds”). The Bonds were issued by the Iowa Finance Authority pursuant to the Heartland Disaster Tax Relief Act of 2008 for the purpose of financing all or part of the cost of acquiring, constructing, reconstructing, and renovating certain facilities (the “Project”) at Arconic’s rolling mill plant in Davenport, IA. The loan proceeds could only be used for this purpose and, therefore, were included on the Company’s Combined Balance Sheet for all periods prior to the Separation Date. In accordance with the Separation and Distribution Agreement, as well as a Second Supplemental Tax and Project Certificate and Agreement, dated March 31, 2020, to the Tax Exemption Certificate and Agreement, dated August 14, 2012, (collectively, the “Tax Agreement”), ParentCo remained the borrower associated with the Bonds and Arconic is the legal owner of the Davenport facility, including the Project. The Company has no financial obligations related to the future debt service of the Bonds but is required to continue to operate, and maintain the location of, the Project in accordance with the Tax Agreement. Accordingly, the $250 carrying value of the Bonds, as well as related accrued interest, was removed from Arconic’s Consolidated Balance Sheet in connection with the Separation.
2028 Notes—Interest on the 2028 Notes is paid semi-annually in February and August and commenced August 15, 2020.
Arconic has the option to redeem the 2028 Notes on at least 10 days, but not more than 60 days, prior notice to the holders of the 2028 Notes under multiple scenarios, including, in whole or in part, at any time or from time to time after February 14, 2023 at a redemption price specified in the indenture (up to 103.063% of the principal amount plus any accrued and unpaid interest in each case). At any time prior to February 15, 2023, the Company may redeem all or a part of the notes at a redemption price equal to 100% of the principal amount of the notes redeemed plus a “make-whole” redemption price

determined as the greater of (1) 1.0% of the principal amount of such notes and (2) the excess, if any, of (a) the present value at the date of redemption of (i) 103.063% of the principal amount of such notes plus (ii) all required interest payments due on such notes (excluding accrued but unpaid interest to the date of redemption) through February 15, 2023, computed using a discount rate equal to, generally, the yield to maturity of United States Treasury securities with a constant maturity as of the date of redemption plus 50 basis points, over (b) the principal amount of such notes, as of, and accrued and unpaid interest, if any, to, but excluding, the date of redemption. Also, at any time prior to February 15, 2023, Arconic may, on one or more occasions, redeem up to 40% of the aggregate principal amount of the notes at a redemption price equal to 106.125% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date, with the net cash proceeds of certain equity offerings, if at least 60% of the original aggregate principal amount of the notes remains outstanding immediately after such redemption and the redemption occurs within 120 days of the date of such equity offering. Additionally, the 2028 Notes are subject to repurchase upon the occurrence of a change in control repurchase event (as defined in the indenture) at a repurchase price in cash equal to 101% of the aggregate principal amount of the 2028 Notes repurchased, plus any accrued and unpaid interest on the 2028 Notes repurchased.
The 2028 Notes are senior secured obligations of Arconic and do not entitle the holders to any registration rights pursuant to a registration rights agreement. The Company does not intend to file a registration statement with respect to resales of or an exchange offer for the 2028 Notes. The 2028 Notes are guaranteed on a senior secured basis by Arconic and its subsidiaries that are guarantors (the “subsidiary guarantors” and, together with Arconic, the “guarantors”) under the ABL Credit Agreement (see below). Each of the subsidiary guarantors will be released from their 2028 Notes guarantees upon the occurrence of certain events, including the release of such guarantor from its obligations as a guarantor under the ABL Credit Agreement.
The 2028 Notes indenture includes several customary affirmative covenants. Additionally, the 2028 Notes indenture contains several negative covenants, that, subject to certain exceptions, limit the Company’s ability to, among other things, (i) make investments, loans, advances, guarantees, and acquisitions, (ii) pay dividends on or make other distributions in respect of capital stock and make other restricted payments and investments (as defined in the 2028 Notes), (iii) sell or transfer certain assets, and (iv) create liens on assets to secure debt.
The 2028 Notes rank equally in right of payment with all of Arconic’s existing and future senior indebtedness, including the facility under the ABL Credit Agreement (see below); rank senior in right of payment to any future subordinated obligations of Arconic; and are effectively subordinated to Arconic’s existing and future secured indebtedness that is secured on a first priority basis, including the 2025 Notes and the facility under the ABL Credit Agreement, to the extent of the value of property and assets securing such indebtedness.
2025 Notes—Interest on the 2025 Notes is paid semi-annually in May and November and commenced November 15, 2020.
Arconic has the option to redeem the 2025 Notes on at least 10 days, but not more than 60 days, prior notice to the holders of the 2025 Notes under multiple scenarios, including, in whole or in part, at any time or from time to time after May 14, 2022 at a redemption price specified in the indenture (up to 103.0% of the principal amount plus any accrued and unpaid interest in each case). At any time prior to May 15, 2022, the Company may redeem all or a part of the notes at a redemption price equal to 100% of the principal amount of the notes redeemed plus a “make-whole” redemption price determined as the greater of (1) 1.0% of the principal amount of such notes and (2) the excess, if any, of (a) the present value at the date of redemption of (i) 103.0% of the principal amount of such notes plus (ii) all required interest payments due on such notes (excluding accrued but unpaid interest to the date of redemption) through May 15, 2022, computed using a discount rate equal to, generally, the yield to maturity of United States Treasury securities with a constant maturity as of the date of redemption plus 50 basis points, over (b) the principal amount of such notes, as of, and accrued and unpaid interest, if any, to, but excluding, the date of redemption. Also, at any time prior to May 15, 2022, Arconic may, on one or more occasions, redeem up to 40% of the aggregate principal amount of the notes at a redemption price equal to 106.0% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date, with the net cash proceeds of certain equity offerings, if at least 60% of the original aggregate principal amount of the notes remains outstanding immediately after such redemption and the redemption occurs within 120 days of the date of such equity offering. Additionally, the 2025 Notes are subject to repurchase upon the occurrence of a change in control repurchase event (as defined in the indenture) at a repurchase price in cash equal to 101% of the aggregate principal amount of the 2025 Notes repurchased, plus any accrued and unpaid interest on the 2025 Notes repurchased.
The 2025 Notes are senior secured obligations of Arconic and do not entitle the holders to any registration rights pursuant to a registration rights agreement. The Company does not intend to file a registration statement with respect to resales of or an exchange offer for the 2025 Notes. The 2025 Notes are guaranteed on a senior secured basis by Arconic and its subsidiaries that are guarantors (the “subsidiary guarantors” and, together with Arconic, the “guarantors”) under the ABL Credit Agreement (see below). Each of the subsidiary guarantors will be released from their 2025 Notes guarantees upon the occurrence of certain events, including the release of such guarantor from its obligations as a guarantor under the ABL Credit Agreement.
106

TABLE OF CONTENTS
The 2025 Notes indenture includes several customary affirmative covenants. Additionally, the 2025 Notes indenture contains several negative covenants, that, subject to certain exceptions, limit the Company’s ability to, among other things, (i) pay dividends on or make other distributions in respect of capital stock and make other restricted payments and investments (as defined in the 2025 Notes), (ii) sell or transfer certain assets, (iii) incur indebtedness, and (iv) create liens on assets to secure debt.
The 2025 Notes are secured on a first priority basis by certain defined collateral (generally consisting of the Company’s and the Guarantors’ equipment, material owned U.S. real property, intellectual property, certain stock, and other tangible and intangible personal property, in each case, subject to certain exceptions) and on a second priority basis by certain other assets (generally consisting of substantially all of the accounts receivable, inventory, deposit accounts, securities accounts, commodities accounts, and cash assets of the Company and the Guarantors, and the proceeds thereof).
ABL Credit Agreement—Availability under the ABL Credit Facility is subject to a monthly borrowing base calculation, which, in general, is determined by applying a predetermined percentage to the amount of eligible accounts receivable and inventory, less customary reserves. As of December 31, 2021, the available balance was $790.
The ABL Credit Facility is scheduled to mature on May 13, 2025, unless extended or earlier terminated in accordance with the ABL Credit Agreement. Under the provision of the ABL Credit Agreement, Arconic will pay a quarterly commitment fee ranging from 0.250% to 0.375% (based on Arconic’s leverage ratio) per annum on the unused portion of the ABL Credit Facility, which will be determined based on the Company’s average daily utilization. The ABL Credit Facility was undrawn as of both December 31, 2021 and 2020 and no amounts were borrowed since inception.
The ABL Credit Facility is subject to an interest rate for U.S. dollar borrowings equal to an applicable margin plus, at the Company’s option, of either (a) base rate (“ABR”) determined by reference to the highest of (1) Deutsche Bank AG New York Branch’s “prime rate,” (2) the greater of the federal funds effective rate and the overnight bank funding rate, plus 0.5%, and (3) the one month adjusted LIBO Rate, plus 1% per annum or (b) an adjusted LIBO Rate (which will not be less than 0.75% per annum) (“LIBOR”). The applicable margin for the ABL Credit Facility through June 30, 2021 was (a) 1.25% for ABR loans and (b) 2.25% for LIBOR loans. Thereafter, the applicable margin for the ABL Credit Facility is (a) 0.75% to 1.25% per annum for ABR loans and (b) 1.75% per annum to 2.25% per annum for LIBOR loans based on the average daily excess availability (as defined under the ABL Credit Agreement). Accordingly, the interest rates for the ABL Credit Facility will fluctuate based on changes in the ABR, LIBOR, and/or future changes in the average daily excess availability.
All obligations under the ABL Credit Facility are unconditionally guaranteed, jointly and severally, by substantially all of the direct and indirect wholly-owned material subsidiaries of the Company that are organized under the laws of the United States, any state thereof or the District of Columbia, subject to certain exceptions (collectively, the “Guarantors”). The Company and the Guarantors entered into a guarantee under the ABL Credit Agreement concurrently with the effectiveness of the ABL Credit Agreement.
Subject to certain limitations, the ABL Credit Facility is secured on a first priority basis by certain defined collateral (generally consisting of substantially all of the accounts receivable, inventory, deposit accounts, securities accounts, commodities accounts, and cash assets of the Company and the Guarantors, and the proceeds thereof) and on a second-priority basis by certain defined collateral under the 2025 Notes (generally consisting of the Company and the Guarantors’ equipment, material owned U.S. real property, intellectual property, certain stock, and other tangible and intangible personal property, in each case, subject to exceptions as defined in the 2025 Notes). The Company and the Guarantors entered into collateral agreements concurrently with the effectiveness of the ABL Credit Agreement.
The ABL Credit Facility contains certain affirmative and negative covenants customary for financings of this type that, among other things, limit the Company’s and its subsidiaries’ ability to incur additional indebtedness or liens, to dispose of assets, to make certain fundamental changes, to enter into restrictive agreements, to make certain investments, loans, advances, guarantees and acquisitions, to prepay certain indebtedness and to pay dividends, to make other distributions or redemptions/repurchases, in respect of the Company’s and its subsidiaries’ equity interests, to engage in transactions with affiliates and to amend certain material documents.
In addition, the ABL Credit Facility contains a financial maintenance covenant applicable to any fiscal quarter in which the excess availability is less than the greater of (a) 10% of the lesser of (x) the aggregate amount of the commitments under the ABL Credit Facility and (y) the borrowing base and (b) $50. In such circumstances, until such time as excess availability shall have exceeded such threshold for at least 30 consecutive days, the Company would be required to maintain a fixed charge coverage ratio of not less than 1.00 to 1.00. The ABL Credit Facility also requires the Company and its subsidiaries to maintain substantially all of the Company’s cash in accounts that are subject to the control of the agent, which control becomes applicable when (a) an event of default under the facility occurs and is continuing until the first day thereafter on which no event of default shall exist or (b) excess availability is less than the greater of (i) 12.5% of the lesser of (x) the aggregate amount
107

TABLE OF CONTENTS
of the commitments under the ABL Credit Facility and (y) the borrowing base or (ii) $62.5 for five consecutive business days until the first day thereafter on which excess availability shall have exceeded such threshold for at least 30 consecutive days.
The ABL Credit Facility contains customary events of default, including with respect to a failure to make payments thereunder, cross-default and cross-acceleration, certain bankruptcy and insolvency events, and customary change of control events.

S. Acquisitions and Divestitures
Divestitures
Itapissuma. On February 1, 2020, Arconic completed the sale of its aluminum rolling mill (aseptic foil and sheet products) in Itapissuma, Brazil to Companhia Brasileira de Alumínio for a net $46 in cash. In December 2020, the Company paid $4 in cash to Companhia Brasileira de Alumínio to settle certain working capital and other post-closing adjustments. Additionally, in June 2021, the Company paid $2 in cash to Companhia Brasileira de Alumínio to settle the remaining working capital and other post-closing adjustments. Arconic has recognized a cumulative loss of $60 (pretax) on this transaction, composed of the following: a charge of $53 in 2019 for the non-cash impairment of the carrying value (i.e., write-down to fair value) of the rolling mill’s net assets, primarily properties, plants, and equipment, as a result of entering into an agreement in August 2019 to sell this rolling mill; a charge of $6 in February 2020 for further necessary adjustments upon completion of the divestiture; and a charge of $1 in March 2021 for a then-proposed final settlement of the remaining post-closing adjustments and other items. Each of these amounts were recorded in Restructuring and other charges (see Note E) on the accompanying Statement of Consolidated Operations in the respective reporting periods. This transaction is no longer subject to post-closing adjustments. Prior to the divestiture, this rolling mill’s operating results and assets and liabilities were reported in Arconic’s Rolled Products segment. The rolling mill generated third-party sales of $143 in 2019 and, at the time of divestiture, had approximately 500 employees.
Changwon. On March 1, 2020, Arconic completed the sale of its hard alloy extrusions plant in South Korea to SeAH Besteel Corporation for a net $55 in cash, resulting in a gain of $31 (pretax), which was recorded in Restructuring and other charges (see Note E) on the accompanying Statement of Consolidated Operations. The gain is net of a $6 write-off of related goodwill. In May 2020, the Company received an additional $1 in cash as a result of a post-closing adjustment, which was previously contemplated in the aforementioned gain. This transaction is no longer subject to post-closing adjustments. Prior to the divestiture, this plant’s operating results and assets and liabilities were reported in Arconic’s Extrusions segment. The extrusions plant generated third-party sales of $51 in 2019 and, at the time of divestiture, had approximately 160 employees.
Texarkana. In October 2018, Arconic 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, subject to post-closing adjustments, plus additional contingent consideration of up to $50. The contingent consideration related to the achievement of various milestones associated with operationalizing the rolling mill equipment within 36 months of the transaction closing date. The Texarkana rolling mill facility had previously been idle since late 2009. In early 2016, the Company restarted the Texarkana cast house to meet demand for aluminum slab. While owned by Arconic, the operating results and assets and liabilities of the business were included in the Company’s Rolled Products segment. As part of the sale agreement, Arconic continued to produce aluminum slab at the facility for a period of 18 months through a lease back of the cast house building and equipment, after which time Ta Chen performed toll processing of metal for the Company for a period of six months. Arconic supplied Ta Chen with cold-rolled aluminum coil during this 24-month period.
108

TABLE OF CONTENTS
The sale of the rolling mill and cast house was accounted for separately. In 2018, a gain on the sale of the rolling mill of $154, including fair value of contingent consideration of $5, was recorded in Restructuring and other charges on the Company’s Statement of Consolidated Operations. In 2020 and 2019, Arconic received additional contingent consideration of $25 and $20, respectively, which was recorded as a gain in Restructuring and other charges (see Note E) on the accompanying Statement of Consolidated Operations in the respective reporting periods. As of December 31, 2020, there was no remaining contingent consideration associated with this transaction.
The Company had continuing involvement related to the lease back of the cast house. As a result, Arconic continued to recognize as assets, as well as depreciate, the cast house building and equipment that it sold to Ta Chen, and recorded the portion of the cash proceeds associated with the sale of the cast house assets as a noncurrent liability, including a deferred gain of $95. As of December 31, 2018, the Company’s Consolidated Balance Sheet included $24 in Properties, plants, and equipment, net, $22 in Deferred income taxes (noncurrent asset), and $119 in Other noncurrent liabilities and deferred credits. On January 1, 2019, Arconic adopted the lease accounting guidance (see Recently Adopted Accounting Guidance in Note B), under which the Company’s continuing involvement no longer required deferral of the recognition of the sale of the cast house. Accordingly, the carrying value of these assets and liabilities were reclassified to equity reflecting a net $73 cumulative effect of an accounting change on the date of adoption.
T. Contingencies and Commitments
Unless specifically described to the contrary, all matters within Note T are the full responsibility of Arconic pursuant to the Separation and Distribution Agreement (see Note A). Additionally, the Separation and Distribution Agreement provides for cross-indemnities between the Company and Howmet for claims subject to indemnification.
Contingencies
Environmental Matters. Arconic participates in environmental assessments and cleanups at several 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, among others, the nature and extent of contamination, changes in remedial requirements, and technological changes.
The Company’s remediation reserve balance was $64 and $156 (of which $15 and $90, respectively, was classified as a current liability) at December 31, 2021 and 2020, respectively, and reflects the most probable costs to remediate identified environmental conditions for which costs can be reasonably estimated.
In 2021, the remediation reserve was reduced by $5 due to a reversal of an $11 liability (a credit was recorded in Cost of goods sold) previously established for the Massena West location (see below) and a charge of $2 (recorded in Restructuring and other charges – see Note E) for the assumption of a remediation obligation related to a legal settlement associated with a former operating site. Additionally, the change to the remediation reserve includes a charge of $4 for other items including incremental estimated expenditures associated with active remediation systems and/or monitoring and inspection programs at several sites.
In 2020, the remediation reserve was reduced by $2 due to the reversal of a $5 liability (a credit was recorded in Restructuring and other charges – see Note E) previously established by ParentCo, as the underlying obligation no longer exists based on an assessment completed by Arconic management; a charge of $1 (recorded in Restructuring and other charges – see Note E) to establish a liability related to the divestiture of a rolling mill in Brazil (see Note S); and a charge of $2 (recorded in Cost of goods sold) for incremental estimated expenditures associated with active remediation systems and/or monitoring and inspection programs at several sites. In 2019, the remediation reserve was increased by $25 (recorded in Cost of goods sold) related to the Grasse River project (see Massena West, NY below).
Payments related to remediation expenses applied against the reserve were $84, $82, and $56 in 2021, 2020, and 2019, respectively, which include expenditures currently mandated, as well as those not required by any regulatory authority or third party. The change in the reserve in 2021 reflects a decrease of $3 for other items and the change in the reserve in 2020 reflects both an increase of $13 for obligations transferred from ParentCo on April 1, 2020 in connection with the Separation (see below) and a decrease of $3 for other items.
The Separation and Distribution Agreement includes provisions for the assignment or allocation of environmental liabilities between Arconic and Howmet Aerospace, including certain remediation obligations associated with environmental matters. In
109

TABLE OF CONTENTS
general, the respective parties are responsible for the environmental matters associated with their operations, and with the properties and other assets assigned to each. Additionally, the Separation and Distribution Agreement lists environmental matters with a shared responsibility between the two companies with an allocation of responsibility and the lead party responsible for management of each matter. For matters assigned to Arconic and Howmet Aerospace under the Separation and Distribution Agreement, the companies have agreed to indemnify each other in whole or in part for environmental liabilities arising from operations prior to the Separation Date.
The following description provides details regarding the Company’s largest reserve (next largest is $5), which relates to one of Arconic’s current operating locations.
Massena West, NY — Arconic has an ongoing remediation project related to the Grasse River, which is adjacent to the Company’s Massena plant site. Many years ago, it was determined that sediments and fish in the river contain varying levels of polychlorinated biphenyls (PCBs). The project, which was selected by the U.S. Environmental Protection Agency (EPA) in a Record of Decision issued in April 2013, is aimed at capping PCB contaminated sediments with concentration in excess of one part per million in the main channel of the river and dredging PCB contaminated sediments in the near-shore areas where total PCBs exceed one part per million. Arconic completed the final design phase of the project, which was approved by the EPA in March 2019. Following the EPA’s approval, the actual remediation fieldwork commenced.
In June 2019, the Company increased the reserve balance by $25 due to changes required in the EPA-approved remedial design and post-construction monitoring. These changes were necessary due to several items, the majority of which related to navigation issues identified by a local seaway development company. Accordingly, the EPA requested an addendum to the final remedial design be submitted to address these issues. The proposed remedy is to dredge certain of the sediments originally identified for capping in the affected areas of the Grasse River, resulting in incremental project costs. The EPA approved the proposal in April 2020.
In 2021, following substantial completion of remedial construction activities on the Grasse River and an assessment of anticipated remaining future costs, primarily for post-construction monitoring, the reserve was reduced by $11. As the project progresses, further changes to the reserve may be required due to factors such as, among others, additional changes in remedial requirements, increased site restoration costs, and incremental ongoing operation and maintenance costs.
At December 31, 2021 and 2020, the reserve balance associated with this matter was $30 and $115, respectively. Approximately $5 of the remaining expenditures represent costs that are expected to be paid in 2022. The other $25 in remaining expenditures, most of which relates to operations, maintenance, and monitoring work, are expected to occur between 2023 and 2027.
Litigation.
All references to ParentCo in the matters described under this section Litigation refer to Arconic Inc. only and do not include its subsidiaries, except as otherwise stated.
Airbus Matters—In 2017, Airbus and various of its affiliates (“Airbus”) filed three separate confidential requests for arbitration against ParentCo and various of its then affiliates, one of which is Arconic Manufacturing (GB) Limited, an Arconic Corporation subsidiary, with the International Chamber of Commerce. Airbus specifically alleged that a defect existed in certain of our products sold to Airbus under various separate contracts. Airbus’s claims included claims of breach of certain alleged express and implied warranties and negligence. On June 12, 2020, Airbus filed its Second Memorial in the arbitration in which it claimed damages attributed specifically to our products. In two of the three arbitrations, Airbus was seeking damages in excess of $200 and an order of indemnification with respect to conditional future losses; in the third of the arbitrations, Airbus was seeking an order of indemnification with respect to contingent future losses. A private and confidential arbitration hearing occurred in late October 2020 on two of the three requests for arbitration and on March 26, 2021, the Arbitral Panel issued final awards in those two arbitrations in favor of the Respondents (including Arconic Manufacturing (GB) Limited), rejecting Airbus’s claims and denying Airbus the relief sought. The hearing on the third request for arbitration was stayed. On June 1, 2021, the parties entered into a confidential agreement in settlement of all claims related to the matter. These proceedings are now fully resolved and closed.
Federal Antimonopoly Service Of The Russian Federation Litigation—The Federal Antimonopoly Service of the Russian Federation (“FAS”) filed a lawsuit on March 17, 2020 with the Arbitrazh (State Commercial) Court of Samara Region against two of the Company’s subsidiaries, Arconic Rus Investment Holdings LLC (“LLC ARIH”) and AlTi Forge Holding Sarl (the “Arconic Russian Holding Companies”), naming Elliott Associates L.P., Elliott International L.P., and Elliot International Capital Advisors Inc. (“Elliott”) as third parties. Also named as interested parties are: Parent Co. and certain of its foreign subsidiaries; and Arconic Netherland B.V., the Company’s subsidiary that directly and indirectly owns LLC ARIH, Arconic SMZ JSC and JSC AlTi Forge (the “Arconic Russian Subsidiaries”). FAS alleges that Elliott indirectly acquired
110

TABLE OF CONTENTS
control over the Arconic Russian Subsidiaries when, in May 2019, directors who had previously been nominated by Elliott and appointed or elected to Parent Co.’s board of directors pursuant to certain settlement agreements among Parent Co. and Elliott constituted a majority of that board as a result of a reduction in the size of the board. FAS claims alleged non-compliance with Russian Federal Law No. 57-FZ, which governs foreign ownership of certain Russian companies and requires certain governmental approvals for a foreign investor to acquire control over strategically important Russian companies. On April 6, 2020, the Samara Court granted injunctions against the Arconic Russian Holding Companies prohibiting the taking of certain corporate governance actions, including with respect to: (i) the disposal of shares in the Arconic Russian Subsidiaries; and (ii) the making of certain decisions with respect to the Arconic Russian Subsidiaries, including decisions regarding the payment of dividends, placement of bonds, amendment of bylaws and internal documents, the appointment, change and compensation of the Arconic Russian Subsidiaries’ CEO, and the election of the Arconic Russian Subsidiaries’ board of directors. On April 29, 2020, the Arconic Russian Holding Companies simultaneously filed an appeal and motion to revoke the previously issued injunctions. Both the appeal and motion to revoke were denied. A hearing on the merits of the claim was scheduled for June 8, 2021 but was postponed until August 19, 2021, again postponed until December 21, 2021, and most recently further postponed until February 22, 2022. As a consequence of the alleged violation, FAS is seeking removal and exclusion of the Arconic Russian Holding Companies from the affairs of the Arconic Russian Subsidiaries, resulting in the deprivation of the benefits of their ownership interests in the Arconic Russian Subsidiaries, including the rights currently restricted in the injunctions granted on April 6, 2020. We continue to operate the Samara location without restrictions other than as disclosed above, and we maintain a renewable intercompany loan facility that could be, but has not as yet been, utilized.
Approximately $79, or 24%, of Arconic’s Cash and cash equivalents at December 31, 2021 is currently held in Russia and is not available for dividends. Cash and cash equivalents held in Russia represented 7% of Arconic’s liquidity (comprised of Cash and cash equivalents of $335 and undrawn availability of $790 under Arconic’s ABL Credit Agreement) at December 31, 2021. In addition, approximately $968, or 16% of third-party sales (including packaging, industrial, aerospace, and defense), and approximately $87, or 13% of Segment Adjusted EBITDA, for the Rolled Products segment for the year ended December 31, 2021 were generated by our Samara, Russia facility. We cannot at this time reasonably estimate the likelihood or timing of any resolution of the regulatory proceedings or underlying claims, whether such resolution would include the removal of the injunctions or the imposition of additional restrictions, or whether we would divest assets related to the Samara facility. The potential impacts of an unfavorable resolution of the proceedings and underlying claims include:
•continued unavailability of funds for the payment of dividends to Arconic Corporation;
•decreases in or loss of third-party sales and Segment Adjusted EBITDA generated by our Samara facility;
•restrictions on capital investments in the facility;
•losses on any potential divestiture;
•the inability of other Arconic facilities to assume capacity to offset decreases in sales or Segment Adjusted EBIDTA or to assume potential divested capacity; and
•increased expenses related to relocation of capacity to other facilities.
Any of the foregoing could have a significant indirect impact on the performance of our other locations. In addition, any impact on our ability to fulfill delivery obligations could subject us to reputational harm and potential litigation involving customers and suppliers. Continued restrictions on our operation of the Samara facility would have a material adverse effect on our financial condition, results of operations or cash flows. Given the preliminary nature of this matter and the uncertainty of litigation and of efforts to resolve this matter with FAS, we 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.
Reynobond PE—On June 13, 2017, the Grenfell Tower in London, U.K. caught fire resulting in fatalities, injuries, and damage. A French subsidiary of Arconic Corporation (of ParentCo at that time), Arconic Architectural Products SAS (AAP SAS), 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 facade installer, who then completed and installed the system under the direction of the general contractor. Neither ParentCo 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. As Phase 2 of the public inquiry continues, the
111

TABLE OF CONTENTS
testimony has supported AAP SAS’s position that the choice of materials and the responsibility of ensuring compliance of the cladding system with relevant U.K. building code and regulations was with those individuals or entities who designed and installed the cladding system such as the architects, fabricators, contractors and building owners. The ongoing hearings in the U.K. have revealed serious doubts about whether these third parties had the necessary qualifications or expertise to carry out the refurbishment work at Grenfell Tower, adequately oversaw the process, conducted the required fire safety testing or analysis, or otherwise complied with their obligations under U.K. regulations. 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 ParentCo 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, Arconic Corporation 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.

•On June 12, 2020, 36 (previously 27) police officers represented by Penningtons Manches Cooper LLP filed suit against AAP SAS, as well as the Royal Borough of Kensington and Chelsea, the Royal Borough of Kensington and Chelsea Tenant Management Organisation Ltd, Celotex Ltd, Exova (U.K.) Ltd, Rydon Maintenance Ltd, Studio E Architects Ltd, Harley Facades Ltd, CEP Architectural Facades Ltd, CS Stokes & Associates Ltd, London Fire Commissioner, and the Commissioner of the Police of the Metropolis. Since then, some claimants have withdrawn and others have sought to be added to the suit.
•On June 12, 2020, two firefighters represented by Pattinson and Brewer filed suit against AAP SAS, as well as the Royal Borough of Kensington and Chelsea, the Royal Borough of Kensington and Chelsea Tenant Management Organisation Ltd, Celotex Ltd, Exova (U.K.) Ltd, Rydon Maintenance Ltd, Studio E Architects Ltd, Harley Facades Ltd, CEP Architectural Facades Ltd, CS Stokes & Associates Ltd, and the London Fire Commissioner. A third firefighter, also represented by Pattinson and Brewer, brought a claim against the same defendants on June 15, 2020. One of the original firefighter claimants has now withdrawn from the suit.
On December 17, 2020, a claim was issued by the Royal Borough of Kensington and Chelsea and the Royal Borough of Kensington and Chelsea Tenant Management Organisation Ltd against: (1) Whirlpool Company Polska Spolka z Organiczona; and (2) AAP SAS. The Claimants seek damages in respect of their own losses and/or a contribution to the extent that they are found to be liable by the London High Court for any losses arising out of the Grenfell Tower fire on June 14, 2017.
All of these claims were filed in the High Court in London. On October 2, 2020, the High Court ordered that: (a) the suits of the survivors and estates of decedents that were issued in June 2020 be stayed until a hearing scheduled by the High Court for June 9-10, 2021; and (b) that the suits of emergency responders be stayed until a hearing scheduled by the High Court for July 7-8, 2021. The hearing scheduled for June 9-10, 2021 was subsequently vacated by the Court.
The above-mentioned suits brought by: (1) the survivors and estates of decedents; (2) the emergency responders; and (3) the Royal Borough of Kensington and Chelsea for contributions, were heard together at a procedural hearing on July 7-8, 2021, before Senior Master Fontaine. At the hearing, the Senior Master made several directions for the future management of the Grenfell Tower litigation, including staying all suits against Arconic Corporation and its affiliates until a directions hearing to be held on the first available date after April 4, 2022. The duration of the stay is intended to allow Arconic Corporation, along with several other co-defendants to the above-mentioned litigations, to engage in preliminary discussions with the claimants' legal representatives in an attempt to reach a mutually agreeable settlement. The parties have now agreed to overarching terms as to the form of Alternative Dispute Resolution that they are willing to participate in. Those discussions are ongoing.
Given the preliminary nature of these matters and the uncertainty of litigation, Arconic Corporation 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 in any of the above-referenced disputes.
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 “ParentCo Defendants”), as well as Saint-Gobain Corporation, d/b/a Celotex and Whirlpool Corporation, in the Court of Common Pleas of Philadelphia County. The complaint alleges claims under Pennsylvania state law for products liability and wrongful death related to the fire. In particular, the plaintiffs allege that the ParentCo 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. The ParentCo Defendants removed the case to the United States District Court for the Eastern District of Pennsylvania on June 19, 2019. On August 29, 2019, the ParentCo Defendants moved to dismiss the complaint on the bases, among other things, that: (i) the case should be heard in the United Kingdom, not the United States; (ii) there is no jurisdiction over necessary parties; and (iii) Pennsylvania product liability law does not apply to manufacture and sale of product overseas. On December 23, 2019, the Court issued an order denying the motion to dismiss the complaint on bases (ii) and (iii) suggesting a procedure for limited discovery followed by further briefing on those subjects. On September 16, 2020, the Court issued an order granting 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 this judgment; ParentCo Defendants are cross-appealing one of the conditions. The briefing has now been completed and the parties are awaiting an oral argument date. Given the preliminary nature of this matter and the uncertainty of litigation, Arconic Corporation 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.

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 ParentCo 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 ParentCo, three former ParentCo executives, several current and former ParentCo directors, and banks that acted as underwriters for ParentCo’s September 18, 2014 preferred stock offering (the “Preferred Offering”). The plaintiff in Sullivan had previously filed a purported class action against the same defendants on July 18, 2017 in the Southern District of New York and, on August 25, 2017, voluntarily dismissed that action without prejudice. On February 7, 2018, on motion from certain putative class members, the court consolidated Howard and Sullivan, closed Sullivan, and appointed lead plaintiffs in the consolidated case. On April 9, 2018, the lead plaintiffs in the consolidated purported class action filed a consolidated amended complaint. The consolidated amended complaint alleged that the registration statement for the Preferred Offering contained false and misleading statements and omitted to state material information, including by allegedly failing to disclose material uncertainties and trends resulting from sales of Reynobond PE for unsafe uses and by allegedly expressing a belief that appropriate risk management and compliance programs had been adopted while concealing the risks posed by Reynobond PE sales. The consolidated amended complaint also alleged that between November 4, 2013 and June 23, 2017 ParentCo and Kleinfeld made false and misleading statements and failed to disclose material information about ParentCo’s commitment to safety, business and financial prospects, and the risks of the Reynobond PE product, including in ParentCo’s Form 10-Ks for the fiscal years ended December 31, 2013, 2014, 2015, and 2016, its Form 10-Qs and quarterly financial press releases from the fourth quarter of 2013 through the first quarter of 2017, its 2013, 2014, 2015, and 2016 Annual Reports, its 2016 Annual Highlights Report, and on its official website. The consolidated amended complaint sought, among other things, unspecified compensatory damages and an award of attorney and expert fees and expenses. On June 8, 2018, all defendants moved to dismiss the consolidated amended complaint for failure to state a claim. On June 21, 2019, the Court granted the defendants’ motion to dismiss in full, dismissing the consolidated amended complaint in its entirety without prejudice. On July 23, 2019, the lead plaintiffs filed a second amended complaint. The second amended complaint alleges generally the same claims as the consolidated amended complaint with certain additional allegations, as well as claims that the risk factors set forth in the registration statement for the Preferred Offering were inadequate and that certain additional statements in the sources identified above were misleading. The second amended complaint seeks, among other things, unspecified compensatory damages and an award of attorney and expert fees and expenses. On September 11, 2019, all defendants moved to dismiss the second amended complaint. Plaintiffs’ opposition to that motion was filed on November 1, 2019 and all defendants filed a reply brief on November 26, 2019. On June 22, 2020, counsel for Arconic Corporation and the individual defendants filed a letter apprising the Court of a recent decision by the Third Circuit and discussing its relevance to the pending motion to dismiss. Pursuant to an Order by the Court directing the plaintiffs to respond to this letter, the plaintiffs filed a letter response on July 9, 2020. On June 23, 2021, the Court granted in part and denied in part the defendants’ motion to dismiss the second amended complaint. The Court dismissed with prejudice plaintiffs’ claim against ParentCo, certain officers and directors and the underwriters based on the registration statement for the Preferred Offering, with the exception of one statement and only as to purchases made before October 23, 2015. In addition, plaintiffs’ claim based on ParentCo’s statements in other SEC filings, in product brochures, and on websites was dismissed in its entirety as to Kleinfeld and dismissed in part and allowed in part as to ParentCo. The Court also dismissed the control-person liability claims in their entirety. On August 11, 2021, ParentCo filed a motion with the district court for certification of an interlocutory appeal and a stay pending appeal. The motion seeks to appeal the aspect of the court’s June 23, 2021 opinion concerning the complaint’s pleading of ParentCo’s alleged scienter. Plaintiffs filed an opposition to the motion on August 17, 2021, and ParentCo filed a reply brief on August 24, 2021. On August 12, 2021, defendants filed an answer to the second amended complaint. A status conference was held before the Court on January 11, 2022 during which the Court heard argument from both parties on the pending motion for certification of an interlocutory appeal. The motion remains pending before the district court. Given the preliminary nature of this matter and the uncertainty of litigation, Arconic Corporation 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.
Raul v. Albaugh, et al. On June 22, 2018, a derivative complaint was filed nominally on behalf of ParentCo by a purported ParentCo stockholder against the then members of ParentCo’s Board of Directors and Klaus Kleinfeld and Ken Giacobbe, naming ParentCo 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 Section 14(a) of the Securities Exchange Act of 1934, as amended, and Delaware state law. On July 13, 2018, the parties filed a stipulation agreeing to stay this case until the final resolution of the Howard case, the Grenfell Tower Public Inquiry in London, and the investigation by the Police and on July 23, 2018, the Court approved the stay. Given the preliminary nature of this matter and the uncertainty of litigation, Arconic Corporation 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.

TABLE OF CONTENTS
General. While Arconic believes that all the above referenced Reynobond PE cases are without merit and intends to challenge them vigorously, there can be no assurances regarding the ultimate resolution of these matters.
Tax. Under the terms of the agreements that govern the 2016 Separation Transaction, Arconic may be entitled to future economic benefits resulting from Alcoa Corporation’s utilization of certain value-added tax credits that were generated, in part, by the Company’s former operations in Brazil in years prior to 2015. Because Arconic is not party to the regulatory filings with the Brazilian government and, therefore, does not have a basis to conclude on the realizability of these value-added tax credits by Alcoa Corporation, the Company will recognize income when amounts are realized, if any.
General. In addition to the matters described above, various other lawsuits, claims, and proceedings have been or may be instituted or asserted against Arconic, 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 is not readily determinable because of the considerable uncertainties that exist. Accordingly, it is possible that the Company's liquidity or results of operations in a reporting 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 Arconic.
Commitments
Purchase Obligations. Arconic has entered into purchase commitments for raw materials, energy, and other goods and services, which total $3,287 in 2022, $270 in 2023, $40 in 2024, $37 in 2025, $35 in 2026, and $24 thereafter as of December 31, 2021.
Operating Leases. See Note P for future minimum contractual obligations under long-term operating leases.

U. 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
115

TABLE OF CONTENTS
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 respective carrying value and fair value of Arconic’s financial instruments were as follows:

|  | 2021 |  | 2020
December 31, |  | Carrying value |  | Fair value |  | Carrying value |  | Fair value
Cash and cash equivalents |  | $ | 335 |  |  | $ | 335 |  |  | $ | 787 |  |  | $ | 787 |
Derivative instruments - assets |  | 1 |  |  | 1 |  |  | 3 |  |  | 3 |
Short-term borrowings |  | — |  |  | — |  |  | 14 |  |  | 14 |
Derivatives instruments - liabilities |  | 23 |  |  | 23 |  |  | 2 |  |  | 2 |
Long-term debt |  | 1,594 |  |  | 1,692 |  |  | 1,278 |  |  | 1,399 |

The following methods were used to estimate the fair value of financial instruments:
Cash and cash equivalents and Short-term borrowings. The carrying amounts approximate fair value because of the short maturity of the instruments. The fair value amounts for Cash and cash equivalents were classified in Level 1 of the fair value hierarchy and Short-term borrowings were classified in Level 2 of the fair value hierarchy.
Derivative instruments. The fair value of financial instruments that hedge forward sale commitments for aluminum and forward purchase commitments for aluminum, natural gas, and certain alloying materials was based on quoted market prices (e.g., aluminum prices on the 10-year London Metal Exchange forward curve) or other significant observable inputs (e.g., regional premiums for aluminum contracts) and were classified in Level 1 or Level 2 of the fair value hierarchy.
Long-term debt. The fair value was based on quoted market prices for public debt and were classified in Level 2 of the fair value hierarchy.
V. Subsequent Events
Management evaluated all activity of Arconic and concluded that no subsequent events have occurred that would require recognition in the Consolidated Financial Statements or disclosure in the Notes to the Consolidated Financial Statements, except as described below.
On January 5, 2022, Arconic entered into a one-year arrangement with a financial institution to sell certain customer receivables outright without recourse on a continuous basis. Under this arrangement, the Company will serve in an administrative capacity, including collection of the receivables from the respective customers and remittance of these cash collections to the financial institution. At no time can the outstanding balance due to the financial institution exceed $100. In January 2022, Arconic sold $113 in customer receivables, of which $77 were included in Receivables from customers on the accompanying Consolidated Balance Sheet as of December 31, 2021, and remitted $28 in cash collections to the financial institution.
On February 16, 2022, the Company’s ABL Credit Agreement was amended to increase the capacity of the ABL Credit Facility to $1,200 from $800 (see Note Q). Additionally, the accordion feature of the ABL Credit Facility has been revised to provide for the Company to request a further increase to the revolving commitments in an aggregate principal amount equal to the greater of $350 and the excess of the borrowing base over the ABL Credit facility commitments. Arconic paid approximately $1 in upfront costs associated with this amendment. The ABL Credit Facility remains undrawn at February 18, 2022.
