PART I

General

We are a global security and aerospace company principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services. We also provide a broad range of management, engineering, technical, scientific, logistics, system integration and cybersecurity services. We serve both U.S. and international customers with products and services that have defense, civil and commercial applications, with our principal customers being agencies of the U.S. Government. In 2020, 74% of our $65.4 billion in net sales were from the U.S. Government, either as a prime contractor or as a subcontractor (including 64% from the Department of Defense (DoD)), 25% were from international customers (including foreign military sales (FMS) contracted through the U.S. Government) and 1% were from U.S. commercial and other customers. Our main areas of focus are in defense, space, intelligence, homeland security and information technology, including cybersecurity.

We operate in an environment characterized by both complexity in global security and continuing economic pressures in the U.S. and globally. A significant component of our strategy in this environment is to focus on program execution, improving the quality and predictability of the delivery of our products and services, and placing security capability quickly into the hands of our U.S. and international customers at affordable prices. Recognizing that our customers are resource constrained, we are endeavoring to develop and extend our portfolio domestically in a disciplined manner with a focus on adjacent markets close to our core capabilities, as well as growing our international sales. We continue to focus on affordability initiatives. We also expect to continue to innovate and invest in technologies to fulfill new mission requirements for our customers, including through acquisitions, and invest in our people so that we have the technical skills necessary to succeed.

We operate in four business segments: Aeronautics, Missiles and Fire Control (MFC), Rotary and Mission Systems (RMS) and Space. We organize our business segments based on the nature of the products and services offered.

Strategic Action

On December 20, 2020, we entered into an agreement to acquire Aerojet Rocketdyne Holdings, Inc. (Aerojet Rocketdyne). We currently expect the transaction to close in the second half of 2021, subject to the satisfaction of customary closing conditions, including regulatory approvals and approval by Aerojet Rocketdyne’s stockholders. For more information regarding the proposed transaction, see Management’s Discussion and Analysis of Financial Condition and Results of Operations, Note 2 – Strategic Action included in our Consolidated Financial Statements and Item 1A - Risk Factors.

Aeronautics

In 2020, our Aeronautics business segment generated net sales of $26.3 billion, which represented 40% of our total consolidated net sales. Aeronautics’ customers include the military services, principally the U.S. Air Force and U.S. Navy, and various other government agencies of the U.S. and other countries, as well as commercial and other customers. In 2020, U.S. Government customers accounted for 69% and international customers accounted for 31% of Aeronautics’ net sales. Net sales from Aeronautics’ combat aircraft products and services represented 33% of our total consolidated net sales in 2020 and 32% in both 2019 and 2018.

Aeronautics is engaged in the research, design, development, manufacture, integration, sustainment, support and upgrade of advanced military aircraft, including combat and air mobility aircraft, unmanned air vehicles and related technologies. Aeronautics’ major programs include:

• F-35 Lightning II Joint Strike Fighter - international multi-role, multi-variant, fifth generation stealth fighter;

• C-130 Hercules - international tactical airlifter;

• F-16 Fighting Falcon - low-cost, combat-proven, international multi-role fighter; and

• F-22 Raptor - air dominance and multi-role fifth generation stealth fighter.

The F-35 program is our largest program, generating 28% of our total consolidated net sales, as well as 69% of Aeronautics’ net sales in 2020. The F-35 program consists of multiple development, production and sustainment contracts. Development is focused on modernization of F-35’s capability and addressing emerging threats. Sustainment provides logistics and training support for the aircraft delivered to F-35 customers.

Production of the aircraft is expected to continue for many years given the U.S. Government’s current inventory objective of 2,456 aircraft for the U.S. Air Force, U.S. Marine Corps and U.S. Navy; commitments from our seven international partner countries and six international customers; as well as expressions of interest from other countries. In 2020, we delivered

Table of Contents

120 aircraft, including 46 to international customers, resulting in total deliveries of 611 production aircraft since program inception. This was a decrease from 134 aircraft delivered in the year ended December 31, 2019 due to the impacts of coronavirus disease 2019 (COVID-19) on the F-35 production rate in 2020 and we expect the production rate in 2021 to continue to be impacted by COVID-19. We have 356 production aircraft in backlog as of December 31, 2020, including orders from our international partner countries. For additional information on the F-35 program, see “Status of the F‑35 Program” in Management’s Discussion and Analysis of Financial Condition and Results of Operations. See also Item 1A - Risk Factors for a discussion of risks related to the F-35 program.

Aeronautics produces and provides support and sustainment services for the C-130J Super Hercules, as well as upgrades and support services for the legacy C-130 Hercules worldwide fleet. We delivered 22 C-130J aircraft in 2020. We have 87 aircraft in our backlog as of December 31, 2020. Our C-130J backlog extends into 2025.

Aeronautics produces F-16 aircraft for international customers and continues to provide service-life extension, modernization and other upgrade programs for our customers’ F‑16 aircraft, with existing contracts continuing for several years. In 2020, the U.S. Government awarded contracts for new production F-16 Block 70/72 aircraft for Taiwan (66 aircraft) and Bulgaria (8 aircraft). As of December 31, 2020, we have 128 F-16 aircraft in backlog. We continue to seek international opportunities to deliver additional aircraft.

Aeronautics continues to provide modernization and sustainment activities for the U.S. Air Force’s F-22 aircraft fleet. The modernization program comprises upgrading existing systems requirements, developing new systems requirements, adding capabilities and enhancing the performance of the weapon systems. The sustainment program consists of sustaining the weapon systems of the F-22 fleet, providing training systems, customer support, integrated support planning, supply chain management, aircraft modifications and heavy maintenance, systems engineering and support products.

In addition to the aircraft programs discussed above, Aeronautics is involved in advanced development programs incorporating innovative design and rapid prototype applications. Our Advanced Development Programs (ADP) organization, also known as Skunk Works®, is focused on future systems, including unmanned and manned aerial systems and next generation capabilities for hypersonics, intelligence, surveillance, reconnaissance, situational awareness and air mobility. We continue to explore technology advancement and insertion into our existing aircraft. We also are involved in numerous network-enabled activities that allow separate systems to work together to increase effectiveness and we continue to invest in new technologies to maintain and enhance competitiveness in military aircraft design, development and production.

Competition

Our broad portfolio of products and services competes both domestically and internationally against products and services of other large aerospace and defense companies, numerous smaller competitors and, increasingly, non-traditional defense contractors. Changes within the industry we operate in, such as vertical integration by our peers, could negatively impact us. We often form teams with our competitors in efforts to provide our customers with the best mix of capabilities to address specific requirements. In some areas of our business, customer requirements are changing to encourage expanded competition. Principal factors of competition include the value of our products and services to the customer; technical and management capability; the ability to develop and implement complex, integrated system architectures; total cost of ownership; our demonstrated ability to execute and perform against contract requirements; and our ability to provide timely and cost effective solutions. Technological advances in such areas as additive manufacturing, data analytics, digital engineering, artificial intelligence, advanced materials, autonomy and robotics, and new business models such as commercial access to space are enabling new factors of competition for both traditional and non-traditional competitors.

The competition for international sales is generally subject to U.S. Government stipulations (e.g., export restrictions, market access, technology transfer, industrial cooperation and contracting practices). We may compete against U.S. and non-U.S. companies (or teams) for contract awards by international governments. International competitions also may be subject to different laws or contracting practices of international governments that may affect how we structure our bid for the procurement. In many international procurements, the purchasing government’s relationship with the U.S. and its industrial cooperation programs are important factors in determining the outcome of a competition. It is common for international customers to require contractors to comply with their industrial cooperation regulations, sometimes referred to as offset requirements, and we have entered into foreign offset agreements as part of securing some international business. For more information concerning offset agreements, see “Contractual Commitments and Off-Balance Sheet Arrangements” in Management’s Discussion and Analysis of Financial Condition and Results of Operations and Item 1A - Risk Factors.

Intellectual Property

We routinely apply for and own a substantial number of U.S. and foreign patents and trademarks related to the products and services we provide. In addition to owning a large portfolio of patents and trademarks, we develop and own other intellectual property, including copyrights, trade secrets and research, development and engineering know-how, which contribute significantly to our business. We also license intellectual property to and from third parties. The Federal Acquisition Regulation (FAR) and Defense Federal Acquisition Regulation Supplement (DFARS) provide that the U.S. Government obtains certain rights in intellectual property, including patents, developed by us and our subcontractors and suppliers in performance of government contracts or with government funding. The U.S. Government may use or authorize others, including competitors, to use such intellectual property. See the discussion of matters related to our intellectual property within Item 1A - Risk Factors. Non-U.S. governments may also have certain rights in patents and other intellectual property developed in performance of our contracts for them. Although our intellectual property rights in the aggregate are important to the operation of our business, we do not believe that any existing patent, license or other intellectual property right is of such importance that its loss or termination would have a material adverse effect on our business taken as a whole.

Raw Materials, Suppliers and Seasonality

Some of our products require relatively scarce raw materials. Historically, we have been successful in obtaining the raw materials and other supplies needed in our manufacturing processes. We seek to manage raw materials supply risk through long-term contracts and by maintaining an acceptable level of the key materials in inventories.

Aluminum and titanium are important raw materials used in certain of our Aeronautics and Space programs. Long-term agreements have helped enable a continued supply of aluminum and titanium. Carbon fiber is an important ingredient in composite materials used in our Aeronautics programs, such as the F-35 aircraft. We have been advised by some suppliers that pricing and the timing of availability of materials in some commodities markets can fluctuate widely. These fluctuations may negatively affect the price and availability of certain materials. While we do not anticipate material problems regarding the supply of our raw materials and believe that we have taken appropriate measures to mitigate these variations, if key materials become unavailable or if pricing fluctuates widely in the future, it could result in delay of one or more of our programs, increased costs or reduced operating profits or cash flows.

Table of Contents

We rely on other companies to provide materials, major components and products, and to perform a portion of the services that are provided to our customers under the terms of most of our contracts. A failure by one or more of these suppliers or subcontractors to provide the agreed-upon supplies or perform the agreed-upon services on a timely basis, according to specifications, or at all, may affect our ability to perform our obligations. While we believe we have taken appropriate measures to mitigate these risks, supplier disruptions, including as a result of COVID-19, could result in delays, increased costs, or reduced operating profits or cash flows. For more information on the risks related to our suppliers and raw materials, see Item 1A. Risk Factors.

No material portion of our business is considered to be seasonal. Various factors can affect the distribution of our sales between accounting periods, including the timing of government awards, the availability of government funding, product deliveries and customer acceptance.

Government Contracts and Regulations

Our business is heavily regulated. We contract with numerous U.S. Government agencies and entities, principally all branches of the U.S. military and NASA. We also contract with similar government authorities in other countries and they regulate our non-FMS international sales. Additionally, our commercial aircraft products are required to comply with U.S. and international regulations governing production and quality systems, airworthiness and installation approvals, repair procedures and continuing operational safety.

We must comply with, and are affected by, laws and regulations relating to the formation, administration and performance of U.S. Government and other governments’ contracts, including foreign governments. These laws and regulations, among other things:

• require certification and disclosure of all cost or pricing data in connection with certain types of contract negotiations;

• impose specific and unique cost accounting practices that may differ from U.S. generally accepted accounting principles (GAAP);

• impose acquisition regulations, which may change or be replaced over time, that define which costs can be charged to the U.S. Government, how and when costs can be charged, and otherwise govern our right to reimbursement under certain U.S. Government and foreign contracts;

• require specific security controls to protect U.S. Government controlled unclassified information and restrict the use and dissemination of information classified for national security purposes and the export of certain products, services and technical data; and compliance with cyber security regulations by our supply chain; and

• require the review and approval of contractor business systems, defined in the regulations as: (i) Accounting System; (ii) Estimating System; (iii) Earned Value Management System, for managing cost and schedule performance on certain complex programs; (iv) Purchasing System; (v) Material Management and Accounting System, for planning, controlling and accounting for the acquisition, use, issuing and disposition of material; and (vi) Property Management System.

The U.S. Government and other governments may terminate any of our government contracts and subcontracts either at its convenience or for default based on our performance. If a contract is terminated for convenience, we generally are protected by provisions covering reimbursement for costs incurred on the contract and profit on those costs. If a contract is terminated for default, we generally are entitled to payments for our work that has been accepted by the U.S. Government or other governments; however, the U.S. Government and other governments could make claims to reduce the contract value or recover its procurement costs and could assess other special penalties. For more information regarding the U.S. Government’s and other governments’ right to terminate our contracts, see Item 1A - Risk Factors. For more information regarding government contracting laws and regulations, see Item 1A - Risk Factors as well as “Critical Accounting Policies - Contract Accounting / Sales Recognition” in Management’s Discussion and Analysis of Financial Condition and Results of Operations. For more information on the risks of doing work internationally, see Item 1A - Risk Factors.

Additionally, our programs for the U.S. Government often operate for periods of time under undefinitized contract actions (UCAs), which means that we begin performing our obligations before the terms, specifications or price are finally agreed to between the parties. Although in most cases we historically have reached mutual agreement to definitize our UCAs, the U.S. Government has the ability to unilaterally definitize contracts and has done so in the past. Absent a successful appeal of such action, the unilateral definitization of the contract obligates us to perform under terms and conditions imposed by the U.S. Government. The U.S. Government’s power to unilaterally definitize a contract can affect our ability to negotiate mutually agreeable contract terms and, if a contract is unilaterally imposed upon us, it may negatively affect our expected profit and cash flows on a program or impose burdensome terms.

A portion of our business is classified by the U.S. Government and cannot be specifically described. The operating results of these classified contracts are included in our consolidated financial statements. The business risks and capital requirements

Table of Contents

associated with classified contracts historically have not differed materially from those of our other U.S. Government contracts. Our internal controls addressing the financial reporting of classified contracts are consistent with our internal controls for our non-classified contracts.

Our operations are subject to and affected by various federal, state, local and foreign environmental protection laws and regulations regarding the discharge of materials into the environment or otherwise regulating the protection of the environment. While the extent of our financial exposure cannot in all cases be reasonably estimated, the costs of environmental compliance have not had, and we do not expect that these costs will have, a material adverse effect on our earnings, financial position and cash flow, primarily because substantially all of our environmental costs are allowable in establishing the price of our products and services under our contracts with the U.S. Government. For information regarding these matters, including current estimates of the amounts that we believe are required for remediation or cleanup to the extent that they are probable and estimable, see “Critical Accounting Policies - Environmental Matters” in Management’s Discussion and Analysis of Financial Condition and Results of Operations and “Note 15 – Legal Proceedings, Commitments and Contingencies” included in our Notes to Consolidated Financial Statements. See also the discussion of environmental matters within Item 1A - Risk Factors.

Research and Development

We conduct research and development (R&D) activities using our own funds (referred to as company-funded R&D or independent research and development (IR&D)) and under contractual arrangements with our customers (referred to as customer-funded R&D) to enhance existing products and services and to develop future technologies. R&D costs include basic research, applied research, concept formulation studies, design, development, and related test activities. See “Note 1 – Significant Accounting Policies” (under the caption “Research and development and similar costs”) included in our Notes to Consolidated Financial Statements.

Human Capital Resources

Due to the specialized nature of our business, our performance depends on identifying, attracting, developing, motivating, and retaining a highly skilled workforce in multiple areas, including engineering, science, manufacturing, information technology, cybersecurity, business development and strategy and management. Our human capital management strategy, which we refer to as our people strategy, is tightly aligned with our business needs and technology strategy. During 2020, our human capital efforts were focused on accelerating the transformation of our technology for workforce management through investments in upgraded systems and processes, and continuing to increase our agility to meet the quickly changing needs of the business, considering the challenges of the global pandemic and social and political unrest. We use a variety of human capital measures in managing our business, including: workforce demographics; diversity metrics with respect to representation, attrition, hiring, promotions and leadership; and talent management metrics including retention rates of top talent and hiring metrics.

Workforce Demographics

As of December 31, 2020, we had a highly skilled workforce made up of approximately 114,000 employees, including approximately 60,000 engineers, scientists and information technology professionals. As of December 31, 2020, approximately 93% of our workforce was located in the U.S. and approximately 20% of our employees are covered by collective bargaining agreements with various unions. A number of our existing collective bargaining agreements expire in any given year. Historically, we have been successful in negotiating renewals to expiring agreements without any material disruption of operating activities, and management considers employee relations to be good.

Diversity and Inclusion

Diversity and inclusion is a business imperative for us, as we believe that it is key to our future success. We have focused our diversity and inclusion initiatives on employee recruitment, including investments in minority-serving institutions and outreach, employee training and development, such as efforts focused on expanding the diverse talent pipeline, and employee engagement, including through participation in our employee Business Resource Groups. Our Business Resource Groups are voluntary, employee-led groups that foster a diverse and inclusive workplace aligned with our organizational mission, values, goals and business practices. Through these and other focused efforts, we have improved the diversity of our overall U.S. workforce and within leadership positions, specifically in the representation of women, People of Color and People with Disabilities.

Table of Contents

Employee Profile (as of December 31, 2020):

(a)Based on employees who self-identify. Includes only U.S. employees and expatriates except for Women, which also includes local country nationals. Excludes casual workers, interns/co-ops and employees of certain subsidiaries and joint ventures.

(b)Executive is defined as director-level (one level below vice president) or higher.

Talent Acquisition, Retention and Development

We strive to hire, develop and retain the top talent in the industry. During 2020, we hired more than 11,000 employees, despite the challenges presented by the COVID-19 pandemic. An integral part of our people strategy is early career hiring through college and intern pipelines, particularly in technical fields. In addition to efforts focused on recruitment, we also monitor employee attrition across a broad array of categories and segments of the population, including with respect to diversity and top talent. Critical to attracting and retaining top talent is employee satisfaction, and we regularly conduct employee engagement surveys to gauge employee satisfaction and to understand the effectiveness of our employee and compensation programs. We attract and reward our employees by providing market competitive compensation and benefit practices, including incentives and recognition plans that extend to all levels in our organization. In addition, we invest in the development of our employees through trainings, apprenticeship programs, leadership development plans and offering tuition assistance programs for continuing education or industry certifications. This employee development helps to make us more competitive and also assists with leadership succession planning throughout the corporation.

Employee Safety and Health

Our safety and health program seeks to optimize our operations through targeted safety, health and wellness opportunities designed to ensure safe work conditions, a healthy work environment, promote workforce resiliency and enhance business value. As part of this program, we track employee health and safety measures, including quarterly and yearly targets related to the number of injury and illness incidents that occur, those incidents that result in days lost, and the number of days lost due to workplace injuries. During 2020, these metrics were negatively impacted by the absence from work and delays in the return to work related to the COVID-19 pandemic. In response to COVID-19, we took action to protect our employees’ safety and health, including by equipping employees with personal protective equipment, establishing minimum staffing and social distancing policies, sanitizing workspaces more frequently, adopting alternate work schedules and instituting other measures aimed at minimizing the transmission of COVID-19 while sustaining production and related services. In addition, we have implemented a flexible teleworking policy for employees who can meet our customer commitments remotely, and a significant portion of our workforce began teleworking in mid-March 2020 and were continuing to telework as of December 31, 2020. For more information on our response to COVID-19, see Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Forward-Looking Statements

This Form 10-K contains statements that, to the extent they are not recitations of historical fact, constitute forward-looking statements within the meaning of the federal securities laws and are based on our current expectations and assumptions. The words “believe,” “estimate,” “anticipate,” “project,” “intend,” “expect,” “plan,” “outlook,” “scheduled,” “forecast” and similar expressions are intended to identify forward-looking statements. These statements are not guarantees of future performance and are subject to risks and uncertainties.

Statements and assumptions with respect to future sales, income and cash flows, program performance, the outcome of litigation, anticipated pension cost and funding, environmental remediation cost estimates, planned acquisitions or dispositions of assets, or the anticipated consequences are examples of forward-looking statements. Numerous factors, including the risk factors described in the following section, could cause our actual results to differ materially from those expressed in our forward-looking statements.

Our actual financial results likely will be different from those projected due to the inherent nature of projections. Given these uncertainties, forward-looking statements should not be relied on in making investment decisions. The forward-looking statements contained in this Form 10-K speak only as of the date of its filing. Except where required by applicable law, we expressly disclaim a duty to provide updates to forward-looking statements after the date of this Form 10-K to reflect subsequent events, changed circumstances, changes in expectations, or the estimates and assumptions associated with them. The forward-looking statements in this Form 10-K are intended to be subject to the safe harbor protection provided by the federal securities laws.

An investment in our common stock or debt securities involves risks and uncertainties. We seek to identify, manage and mitigate risks to our business, but risk and uncertainty cannot be eliminated or necessarily predicted. The outcome of one or more of these risks could have a material effect on our operating results, financial position, or cash flows. You should carefully consider the following factors, in addition to the other information contained in this Annual Report on Form 10-K, before deciding to purchase our common stock or debt securities.

Risks Related to our Reliance on Government Contracts

We depend heavily on contracts with the U.S. Government, including contracts related to the F-35 program, for a substantial portion of our business. Changes in the U.S. Government’s priorities and delays or reductions in spending could have a material adverse effect on our business.

We derived 74% of our total net sales from the U.S. Government in 2020, including 64% from the DoD. We expect to continue to derive most of our sales from work performed under U.S. Government contracts. Those contracts are conditioned upon the continuing availability of Congressional appropriations. Congress usually appropriates funds on a fiscal year (FY) basis even though contract performance may extend over many years. Consequently, contracts are often partially funded initially and additional funds are committed only as Congress makes further appropriations. If we incur costs in excess of funds obligated on a contract, we may be at risk for reimbursement of those costs unless and until additional funds are obligated to the contract.

The F-35 program, which consists of multiple development, production and sustainment contracts, is our largest program. It represented 28% of our total net sales in 2020. A decision by the U.S. Government or other governments to cut spending on this program or reduce or delay planned orders would have an adverse impact on our business and results of operations. Given the size and complexity of the F-35 program, we anticipate that there will be continual reviews related to aircraft performance, program schedule, cost, and requirements as part of the DoD, Congressional, and international partners’ oversight and budgeting processes. Current program challenges include, but are not limited to, supplier and partner performance (including COVID-19 related challenges), software development, the availability and receipt of funding for contracts on a timely basis, execution of future flight tests and findings resulting from testing and operating the aircraft, the level of cost associated with life-cycle operations and sustainment and warranties, continuing to reduce the unit production costs, and achieving cost targets.

Budget uncertainty, the risk of future budget cuts, the potential for U.S. government shutdowns, the use of continuing resolutions, and the federal debt ceiling can adversely affect our industry and the funding for our programs. If a government

Table of Contents

shutdown were to occur and were to continue for an extended period of time, we could be at risk of program cancellations and other disruptions and nonpayment. If the U.S. Government operates under a continuing resolution, new contract and program starts are restricted and funding for our programs may be unavailable, reduced or delayed. Shifting funding priorities, including COVID-19 related spending, or federal budget compromises, could also result in reductions in overall defense spending which could adversely impact our business. Our business could also be adversely impacted by reductions or delays in spending by non-U.S. government customers who are facing budget pressures.

We believe our diverse range of products and services generally make it less likely that cuts in any specific contract or program will affect our business on a long-term basis. However, termination of multiple or large programs or contracts could adversely affect our business and future financial performance. Changes in funding priorities may afford new or additional opportunities for our businesses in terms of existing, follow-on or replacement programs, but could also reduce opportunities in existing programs and in planned programs where we intend to compete. While we would expect to compete and be well positioned as the incumbent on existing programs, we may not be successful or, even if successful, the replacement programs may be funded at lower levels.

We are subject to a number of procurement laws and regulations, including the U.S. Government’s ability to terminate contracts for convenience. Our business and reputation could be adversely affected if we or those we do business with fail to comply with these laws.

We must comply with and are affected by laws and regulations relating to the award, administration and performance of U.S. Government contracts. Government contract laws and regulations affect how we do business with our customers and impose certain risks and costs on our business. A violation of these laws and regulations by us, our employees, others working on our behalf, a supplier or a joint venture partner could harm our reputation and result in the imposition of fines and penalties, the termination of our contracts, suspension or debarment from bidding on or being awarded contracts, loss of our ability to export products or perform services and civil or criminal investigations or proceedings. In addition, costs to comply with new government regulations can increase our costs, reduce our margins and affect our competitiveness.

In some instances, these laws and regulations impose terms or obligations that are different than those typically found in commercial transactions. For example, the U.S. Government may terminate any of our government contracts and subcontracts not only for default based on our performance but also at its convenience. Upon termination for convenience of a fixed-price type contract, typically we are entitled to receive the purchase price for delivered items, reimbursement for allowable costs for work-in-process and an allowance for profit on the contract or adjustment for loss if completion of performance would have resulted in a loss.

Upon termination for convenience of a cost-reimbursable contract, we normally are entitled to reimbursement of allowable costs plus a portion of the fee, and allowable costs include our cost to terminate agreements with our suppliers and subcontractors. The amount of the fee recovered, if any, is related to the portion of the work accomplished prior to termination and is determined by negotiation. We attempt to ensure that adequate funds are available by notifying the customer when its estimated costs, including those associated with a possible termination for convenience, approach levels specified as being allotted to its programs. As funds are typically appropriated on a fiscal year basis, and because the costs of a termination for convenience may exceed the costs of continuing a program in a given fiscal year, programs occasionally do not have sufficient funds appropriated to cover the termination costs if the government were to terminate them for convenience. Under such circumstances, the U.S. Government could assert that it is not required to appropriate additional funding.

A termination arising out of our default may expose us to liability and have a material adverse effect on our ability to compete for future contracts and orders. In addition, on those contracts for which we are teamed with others and are not the prime contractor, the U.S. Government could terminate a prime contract under which we are a subcontractor, notwithstanding the fact that our performance and the quality of the products or services we delivered were consistent with our contractual obligations as a subcontractor. In the case of termination for def

At December 31, 2020, we owned or leased building space (including offices, manufacturing plants, warehouses, service centers, laboratories and other facilities) at approximately 385 locations primarily in the U.S. Additionally, we manage or occupy approximately 15 government-owned facilities under lease and other arrangements. At December 31, 2020, we had significant operations in the following locations:

• Aeronautics - Palmdale, California; Marietta, Georgia; Greenville, South Carolina; and Fort Worth, Texas.

• Missiles and Fire Control - Camden, Arkansas; Ocala and Orlando, Florida; Lexington, Kentucky; and Grand Prairie, Texas.

• Rotary and Mission Systems - Shelton and Stratford, Connecticut; Orlando, Florida; Moorestown/Mt. Laurel, New Jersey; Owego and Syracuse, New York; Manassas, Virginia; and Mielec, Poland.

• Space - Huntsville, Alabama; Sunnyvale, California; Denver, Colorado; Cape Canaveral, Florida; Valley Forge, Pennsylvania; and Reading, England.

• Corporate activities - Bethesda, Maryland.

The following is a summary of our square feet of floor space owned, leased, or utilized by business segment at December 31, 2020 (in millions):

We believe our facilities are in good condition and adequate for their current use. We may improve, replace or reduce facilities as considered appropriate to meet the needs of our operations.

We are a party to or have property subject to litigation and other proceedings that arise in the ordinary course of our business, including matters arising under provisions relating to the protection of the environment, and are subject to contingencies related to certain businesses we previously owned. These types of matters could result in fines, penalties, cost reimbursements or contributions, compensatory or treble damages or non-monetary sanctions or relief. We believe the probability is remote that the outcome of each of these matters will have a material adverse effect on the corporation as a whole, notwithstanding that the unfavorable resolution of any matter may have a material effect on our net earnings in any particular interim reporting period. We cannot predict the outcome of legal or other proceedings with certainty.

We are subject to federal, state, local and foreign requirements for the protection of the environment, including those for discharge of hazardous materials and remediation of contaminated sites. Due in part to the complexity and pervasiveness of these requirements, we are a party to or have property subject to various lawsuits, proceedings and remediation obligations. The extent of our financial exposure cannot in all cases be reasonably estimated at this time.

For information regarding the matters discussed above, including current estimates of the amounts that we believe are required for remediation or clean-up to the extent estimable, see “Critical Accounting Policies - Environmental Matters” in Management’s Discussion and Analysis of Financial Condition and Results of Operations and “Note 15 – Legal Proceedings, Commitments and Contingencies” included in our Notes to Consolidated Financial Statements.

As a U.S. Government contractor, we are subject to various audits and investigations by the U.S. Government to determine whether our operations are being conducted in accordance with applicable regulatory requirements. U.S. Government investigations of us, whether relating to government contracts or conducted for other reasons, could result in administrative, civil, or criminal liabilities, including repayments, fines or penalties being imposed upon us, suspension, proposed debarment, debarment from eligibility for future U.S. Government contracting, or suspension of export privileges. Suspension or debarment could have a material adverse effect on us because of our dependence on contracts with the U.S. Government. U.S. Government investigations often take years to complete and many result in no adverse action against us. We also provide products and services to customers outside of the U.S., which are subject to U.S. and foreign laws and regulations and foreign procurement policies and practices. Our compliance with local regulations or applicable U.S. Government regulations also may be audited or investigated.

Purchases of Equity Securities

There were no sales of unregistered equity securities during the quarter ended December 31, 2020.

The following table provides information about our repurchases of our common stock registered pursuant to Section 12 of the Exchange Act of 1934 during the quarter ended December 31, 2020.

(a)We close our books and records on the last Sunday of each month to align our financial closing with our business processes, except for the month of December, as our fiscal year ends on December 31. As a result, our fiscal months often differ from the calendar months. For example, October 26, 2020 was the first day of our November 2020 fiscal month.

(b)In October 2010, our Board of Directors approved a share repurchase program pursuant to which we are authorized to repurchase our common stock in privately negotiated transactions or in the open market at prices per share not exceeding the then-current market prices. From time to time, our Board of Directors authorizes increases to our share repurchase program. The total remaining authorization for future common share repurchases under our share repurchase program was $3.0 billion as of December 31, 2020. Under the program, management has discretion to determine the dollar amount of shares to be repurchased and the timing of any repurchases in compliance with applicable law and regulation. This includes purchases pursuant to Rule 10b5-1 plans, including accelerated share repurchases. The program does not have an expiration date.

(c)During the quarter ended December 31, 2020, the total number of shares purchased included 9,987 shares that were transferred to us by employees in satisfaction of tax withholding obligations associated with the vesting of restricted stock units. These purchases were made pursuant to a separate authorization by our Board of Directors and are not included within the program.

Table of Contents

(a)Our operating profit and net earnings from continuing operations and earnings per share from continuing operations were affected by severance charges of $27 million ($21 million, or $0.08 per share, after-tax) in 2020 primarily related to corporate functions, severance and restructuring charges of $96 million ($76 million, or $0.26 per share, after-tax) in 2018 and severance charges of $80 million ($52 million, or $0.17 per share, after-tax) in 2016.

(b)The impact of our postretirement benefit plans can cause our operating profit, net earnings, cash flows and certain amounts recorded on our consolidated balance sheets to fluctuate. Accordingly, our net earnings were affected by a net FAS/CAS pension adjustment of $2.1 billion in 2020, $1.5 billion in 2019, $1.0 billion in 2018, $876 million in 2017, and $902 million in 2016. We made pension contributions of $1.0 billion in 2020, $1.0 billion in 2019, $5.0 billion in 2018, $46 million in 2017, and $23 million in 2016, and these contributions caused fluctuations in our operating cash flows and cash balance between each of those years. See “Critical Accounting Policies - Postretirement Benefit Plans” in Management’s Discussion and Analysis of Financial Condition and Results of Operations for more information.

(c)Cash generated from operations for the year ended December 31, 2020 reflects the receipt of approximately $1.2 billion of net accelerated progress payments due to the U.S. Government's increase in the progress payment rate from 80 percent to 90 percent and the deferral of $460 million for the employer portion of payroll taxes to 2021 and 2022 pursuant to the CARES Act. We used the accelerated progress payments from the U.S. Government plus cash on hand to accelerate $2.1 billion of payments to our suppliers as of December 31, 2020 that are due by their terms in future periods.

(d)In 2019 and 2017, we recorded a previously deferred non-cash gain of $51 million ($38 million, or $0.13 per share, after-tax) and $198 million ($122 million, or $0.42 per share, after-tax) related to properties sold in 2015 as a result of completing our remaining obligations.

Table of Contents

(e)For the year ended December 31, 2019, net earnings include a gain of $34 million (approximately $0 after-tax) for the sale of our Distributed Energy Solutions business.

(f)For the year ended December 31, 2020 and 2018, operating profit includes a non-cash asset impairment charge of $128 million ($96 million, or $0.34 per share, after-tax) and $110 million ($83 million, or $0.29 per share, after-tax) related to our equity method investee, Advanced Military Maintenance, Repair and Overhaul Center LLC (AMMROC). For the year ended December 31, 2017, operating profit includes a $64 million ($40 million, or $0.14 per share, after-tax) charge, which represents our portion of a non-cash asset impairment charge recorded by AMMROC. See “Note 1 – Significant Accounting Policies” included in our Notes to Consolidated Financial Statements for more information.

(g)In 2017, we recorded a net one-time tax charge of $2.0 billion ($6.77 per share), substantially all of which was non-cash, primarily related to the estimated impact of the Tax Cuts and Jobs Act of 2017 (see “Note 10 – Income Taxes” included in our Notes to Consolidated Financial Statements). This charge along with our annual re-measurement adjustment related to our postretirement benefit plans of $1.4 billion resulted in a deficit in our total equity as of December 31, 2017.

(h)Net earnings for the year ended December 31, 2019 include benefits of $127 million ($0.45 per share) for additional tax deductions for the prior year, primarily attributable to foreign derived intangible income treatment based on proposed tax regulations released on March 4, 2019 and a change in our tax accounting method. Net earnings for the year ended December 31, 2018 include benefits of $146 million ($0.51 per share) for additional tax deductions for the prior year, primarily attributable to true-ups to the net one-time charges related to the Tax Cuts and Jobs Act enacted on December 22, 2017 and our change in tax accounting method (see “Note 10 – Income Taxes” included in our Notes to Consolidated Financial Statements).

(i)Discontinued operations for the year ended December 31, 2020 include a $55 million ($0.20 per share) non-cash charge resulting from the resolution of certain tax matters related to the former Information Systems & Global Solutions (IS&GS) business divested in 2016. Discontinued operations for the year ended December 31, 2016 include a $1.2 billion net gain related to the divestiture of our IS&GS business in 2016.

(j)Effective January 1, 2019, we adopted Accounting Standards Update (ASU) 2016-02, Leases (Topic 842). As of December 31, 2019, right-of-use operating lease assets were $1.0 billion and operating lease liabilities were $1.1 billion. Approximately $855 million of operating lease liabilities were classified as noncurrent. There was no impact to our consolidated statements of earnings or cash flows as a result of adopting this standard. Prior periods were not restated for the adoption of ASU 2016-02. See “Note 9 – Leases” included in our Notes to Consolidated Financial Statements.

Business Overview

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations (MD&A) is intended to help the reader understand our results of operations and financial condition. The MD&A is provided as a supplement to, and should be read in conjunction with, our consolidated financial statements and notes thereto included in Item 8 - Financial Statements and Supplementary Data.

The MD&A generally discusses 2020 and 2019 items and year-to-year comparisons between 2020 and 2019. Discussions of 2018 items and year-to-year comparisons between 2019 and 2018 that are not included in this Form 10-K can be found in “Management’s Discussion and Analysis of Financial Condition and Results or Operations” in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2019 filed with the SEC on February 7, 2020.

We are a global security and aerospace company principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services. We also provide a broad range of management, engineering, technical, scientific, logistics, system integration and cybersecurity services. We serve both U.S. and international customers with products and services that have defense, civil and commercial applications, with our principal customers being agencies of the U.S. Government. In 2020, 74% of our $65.4 billion in net sales were from the U.S. Government, either as a prime contractor or as a subcontractor (including 64% from the Department of Defense (DoD)), 25% were from international customers (including foreign military sales (FMS) contracted through the U.S. Government) and 1% were from U.S. commercial and other customers. Our main areas of focus are in defense, space, intelligence, homeland security and information technology, including cybersecurity.

We operate in four business segments: Aeronautics, Missiles and Fire Control (MFC), Rotary and Mission Systems (RMS) and Space. We organize our business segments based on the nature of the products and services offered.

We operate in an environment characterized by both complexity in global security and continuing economic pressures in the U.S. and globally. A significant component of our strategy in this environment is to focus on program execution, improving the quality and predictability of the delivery of our products and services, and placing security capability quickly into the hands of our U.S. and international customers at affordable prices. Recognizing that our customers are resource constrained, we are endeavoring to develop and extend our portfolio domestically in a disciplined manner with a focus on adjacent markets close to our core capabilities, as well as growing our international sales. We continue to focus on affordability initiatives. We also expect to continue to innovate and invest in technologies to fulfill new mission requirements for our customers, including through acquisitions, and invest in our people so that we have the technical skills necessary to succeed.

COVID-19

The global outbreak of the coronavirus disease 2019 (COVID-19) was declared a pandemic by the World Health Organization and a national emergency by the U.S. Government in March 2020 and has negatively affected the U.S. and global economies, disrupted global supply chains, resulted in significant travel and transport restrictions, including mandated closures and orders to “shelter-in-place” and quarantine restrictions. We have taken measures to protect the health and safety of our employees, work with our customers and suppliers to minimize disruptions and support our community in addressing the challenges posed by this ongoing global pandemic. The pandemic has presented unprecedented business challenges, and we have experienced impacts in each of our business areas related to COVID-19, primarily in increased coronavirus-related costs, delays in supplier deliveries, impacts of travel restrictions, site access and quarantine requirements, and the impacts of remote work and adjusted work schedules.

Despite these challenges, Lockheed Martin and the U.S. Government’s pro-active efforts, especially with regard to the supply chain, helped to partially mitigate the disruptions caused by COVID-19 on our operations in 2020. In addition, favorable contract award timing, strong operational performance and lower travel and overhead expenditures due to COVID-19 restrictions partially offset the impacts of COVID-19 on our financial results in 2020. However, the ultimate impact of COVID-19 on our operations and financial performance in future periods, including our ability to execute our programs in the expected timeframe, remains uncertain and will depend on future pandemic related developments, including the duration of the pandemic, any potential subsequent waves of COVID-19 infection, the effectiveness, distribution and acceptance of COVID-19 vaccines, and related government actions to prevent and manage disease spread, all of which are uncertain and cannot be predicted. The long-term impacts of COVID-19 on government budgets and other funding priorities, including international priorities, that impact demand for our products and services and our business are also difficult to predict but could negatively affect our future results of operations. For additional risks to the corporation related to the COVID-19 pandemic, see Item 1A - Risk Factors.

In accordance with the Department of Homeland Security’s identification of the Defense Industrial Base as a critical infrastructure sector in March 2020, our U.S. production facilities have continued to operate in support of essential products and services required to meet national security commitments to the U.S. Government and the U.S. military. Although we are designated as a critical infrastructure workforce, operations have been adjusted in response to the pandemic, including, most significantly, a reduction in the F-35 production rate primarily due to supplier delays. The reduction delayed 2020 F-35 deliveries by 18 aircraft. Due to the supplier delays, we implemented a temporary schedule adjustment for the F-35 production workforce in Fort Worth, Texas. While the F-35 production workforce resumed their pre-COVID-19 work schedule in the third quarter of 2020, staffing levels at our facilities, our customer facilities, and our supplier facilities have and could continue to fluctuate as a result of COVID-19, which could negatively impact our business. In addition, countries other than the U.S. have different responses to the pandemic that can affect our international operations and the operations of our suppliers and customers. Base closures, travel restrictions, and quarantine requirements both within and outside the U.S. have affected our normal operations and resulted in some schedule delays and future or prolonged occurrences of these could adversely affect our ability to achieve future contract milestones and our results of operations.

The U.S. Government has taken actions in response to COVID-19 to increase the progress payment rates in new and existing contracts and accelerate contract awards to provide cash flow and liquidity for companies in the Defense Industrial Base, including large prime contractors like Lockheed Martin and smaller suppliers. We continue to proactively monitor our supply chain and have implemented multiple actions to help mitigate the effects of COVID-19, including accelerating payments to suppliers within our global supply base as a result of the actions taken by the DoD in changing the progress payment policy. We plan to continue to accelerate payments to the supply chain assuming the continuation of the current DoD progress payment policy in order to mitigate COVID-19 risks, prioritizing impacted suppliers and small busi

We maintain active relationships with a broad and diverse group of U.S. and international financial institutions. We believe that they provide us with sufficient access to the general and trade credit we require to conduct our business. We continue to closely monitor the financial market environment and actively manage counterparty exposure to minimize the potential impact from adverse developments with any single credit provider while ensuring availability of, and access to, sufficient credit resources.

Our main exposure to market risk relates to interest rates, foreign currency exchange rates and market prices on certain equity securities. Our financial instruments that are subject to interest rate risk principally include fixed-rate long-term debt and commercial paper, if issued. The estimated fair value of our outstanding debt was $16.9 billion at December 31, 2020 and the outstanding principal amount was $13.3 billion, excluding unamortized discounts and issuance costs of $1.1 billion. A 10% change in the level of interest rates would not have a material impact on the fair value of our outstanding debt at December 31, 2020.

We use derivative instruments principally to reduce our exposure to market risks from changes in foreign currency exchange rates and interest rates. We do not enter into or hold derivative instruments for speculative trading purposes. We transact business globally and are subject to risks associated with changing foreign currency exchange rates. We enter into foreign currency hedges such as forward and option contracts that change in value as foreign currency exchange rates change. Our most significant foreign currency exposures relate to the British pound sterling, the euro, the Canadian dollar and the Australian dollar. These contracts hedge forecasted foreign currency transactions in order to mitigate fluctuations in our earnings and cash flows associated with changes in foreign currency exchange rates. As a result, we do not have material foreign currency transaction exposure, including exposure to the pound sterling or euro should there be material foreign currency fluctuations due to the United Kingdom departing from the European Union (commonly referred to as Brexit). We designate foreign currency hedges as cash flow hedges. We also are exposed to the impact of interest rate changes primarily through our borrowing activities. For fixed rate borrowings, we may use variable interest rate swaps, effectively converting fixed rate borrowings to variable rate borrowings in order to hedge changes in the fair value of the debt. These swaps are designated as fair value hedges. For variable rate borrowings, we may use fixed interest rate swaps, effectively converting variable rate borrowings to fixed rate borrowings in order to mitigate the impact of interest rate changes on earnings. These swaps are designated as cash flow hedges. We also may enter into derivative instruments that are not designated as hedges and do not qualify for hedge accounting, which are intended to mitigate certain economic exposures.

The classification of gains and losses resulting from changes in the fair values of derivatives is dependent on our intended use of the derivative and its resulting designation. Adjustments to reflect changes in fair values of derivatives attributable to highly effective hedges are either reflected in earnings and largely offset by corresponding adjustments to the hedged items or reflected net of income taxes in accumulated other comprehensive loss until the hedged transaction is recognized in earnings. Changes in the fair value of the derivatives that are not highly effective, if any, are immediately recognized in earnings. The aggregate notional amount of our outstanding interest rate swaps at December 31, 2020 and 2019 was $572 million and $750 million. The aggregate notional amount of our outstanding foreign currency hedges at December 31, 2020 and 2019 was $3.4 billion and $3.8 billion. At December 31, 2020 and 2019, the net fair value of our derivative instruments was not material (see “Note 17 – Fair Value Measurements” included in our Notes to Consolidated Financial Statements). A 10% unfavorable exchange rate movement of our foreign currency contracts would not have a material impact on the aggregate net fair value of such contracts or our consolidated financial statements. Additionally, as we enter into foreign currency contracts to hedge foreign currency exposure on underlying transactions we believe that any movement on our foreign currency contracts would be offset by movement on the underlying transactions and, therefore, when taken together do not create material risk.

We evaluate the credit quality of potential counterparties to derivative transactions and only enter into agreements with those deemed to have acceptable credit risk at the time the agreements are executed. Our foreign currency exchange hedge portfolio is diversified across several banks. We periodically monitor changes to counterparty credit quality as well as our concentration of credit exposure to individual counterparties. We do not hold or issue derivative financial instruments for trading or speculative purposes.

We maintain a separate trust that includes investments to fund certain of our non-qualified deferred compensation plans. As of December 31, 2020, investments in the trust totaled $2.0 billion and are reflected at fair value on our consolidated balance sheet in other noncurrent assets. The trust holds investments in marketable equity securities and fixed-income securities that are exposed to price changes and changes in interest rates. A portion of the liabilities associated with the deferred compensation plans supported by the trust is also impacted by changes in the market price of our common stock and certain market indices. Changes in the value of the liabilities have the effect of partially offsetting the impact of changes in the value of the trust. Both the change in the fair value of the trust and the change in the value of the liabilities are recognized on our consolidated statements of earnings in other unallocated, net and were not material for the year ended December 31, 2020.

Lockheed Martin Corporation

Opinion on Internal Control over Financial Reporting

We have audited Lockheed Martin Corporation’s internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Lockheed Martin Corporation (the Corporation) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Corporation as of December 31, 2020 and 2019, the related consolidated statements of earnings, comprehensive income, equity and cash flows for each of the three years in the period ended December 31, 2020, and the related notes and our report dated January 28, 2021 expressed an unqualified opinion thereon.

Basis for Opinion

The Corporation’s management is responsible 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 an opinion on the Corporation’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Corporation 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

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 (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) 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 (3) 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.
