We are focused on competing and winning programs that enable continued growth, performing on our commitments and affordably delivering capability our customers need. With the investments we've made in advanced technologies, combined with our talented workforce and digital transformation capabilities, Northrop Grumman is well positioned to meet our customers' needs today and in the future. For a discussion of risks associated with our operations, see “Risk Factors.”
The company originally was formed in 1939 in Hawthorne, California as Northrop Aircraft Incorporated and was reincorporated in Delaware in 1985, as Northrop Corporation. Northrop Corporation was a principal developer of flying wing technology, including the B-2 Spirit stealth aircraft. We developed into one of the largest defense technology companies in the world through a series of acquisitions, as well as organic growth, including the following:
•1994 - Acquired Grumman Corporation, a premier military aircraft systems integrator. The combined company was renamed Northrop Grumman Corporation;
•1996 - Acquired the defense and electronics businesses of Westinghouse Electric Corporation, developer of sophisticated radar and other electronics systems;
•2001 - Acquired Litton Industries, Inc., a global electronics and information technology company and full service shipbuilder;
•2001 - Acquired Newport News Shipbuilding Inc., designer and builder of nuclear-powered aircraft carriers and submarines;
•2002 - Acquired TRW Inc., developer of military and civil space systems and payloads, and integrator of complex, mission-enabling systems and services;
•2011 - Completed the spin-off of Huntington Ingalls Industries, Inc., operator of our former shipbuilding business, comprised largely of a part of Litton Industries and Newport News Shipbuilding;
•2018 - Acquired Orbital ATK, Inc. (OATK), developer and producer of satellites and other space systems, launch vehicles and missile products; and
•2021 - Completed the sale of our IT and mission support services business (the “IT services divestiture”) to Veritas Capital.
Organization
From time to time, we acquire or dispose of businesses and realign contracts, programs or businesses among and within our operating segments. Internal realignments are typically designed to leverage existing capabilities more fully and to enhance efficient development and delivery of products and services. At December 31, 2024, the company was aligned in four operating sectors, which also comprise our reportable segments: Aeronautics Systems, Defense Systems, Mission Systems and Space Systems.
Effective July 1, 2024, the company realigned the Strategic Deterrent Systems (SDS) division, which includes the Ground-Based Strategic Deterrent (“Sentinel”) program, from Space Systems to Defense Systems. This realignment is reflected in the financial information contained in this report.
NORTHROP GRUMMAN CORPORATION
Subsequent Realignment - Effective January 1, 2025, the company realigned the Strike and Surveillance Aircraft Solutions (SSAS) business unit from Defense Systems to Aeronautics Systems.

CUSTOMER CONCENTRATION
Our largest customer is the U.S. government. Sales to the U.S. government accounted for 87 percent, 86 percent and 86 percent of sales during the years ended December 31, 2024, 2023 and 2022, respectively. For further information on sales by customer type, contract type and geographic region, see Note 15 to the consolidated financial statements. See “Risk Factors” for further discussion regarding risks related to customer concentration.
COMPETITIVE CONDITIONS
We compete with many companies in the defense, intelligence and federal civil markets. The Boeing Company, General Dynamics, L3Harris Technologies, Lockheed Martin, and RTX are some of our primary competitors. Key characteristics of our industry include long operating cycles and intense competition, which is evident through the number of competitors bidding on program opportunities and the number of competitor protests of U.S. government procurement awards.
It is common in the defense industry for work on major programs to be shared among a number of companies. A company competing to be a prime contractor may, upon ultimate award of the contract to another competitor, serve as a subcontractor to the ultimate prime contracting company. It is not unusual to compete for a contract award with a peer company and, simultaneously, perform as a supplier to or a customer of that same competitor on other contracts, or vice versa.
SEASONALITY
No material portion of our business is seasonal.
NORTHROP GRUMMAN CORPORATION
BACKLOG
At December 31, 2024, total backlog, which is equivalent to the company’s remaining performance obligations, was $91.5 billion as compared with $84.2 billion at December 31, 2023. For further information, see “Backlog” in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” (MD&A) and Note 1 to the consolidated financial statements.
INTELLECTUAL PROPERTY
We protect our technological innovations using a combination of trade secrets, patents, trademarks, and copyrights. We routinely apply for patents related to the technologies we develop in the U.S. and in certain foreign jurisdictions. We license some intellectual property rights to third parties and we also license or otherwise obtain access to intellectual property from third parties. The U.S. government typically holds licenses to patents developed in the performance of U.S. government contracts and may use or authorize others to use the inventions covered by these patents for certain purposes. See “Risk Factors” for further discussion regarding risks related to intellectual property.
RAW MATERIALS
We have experienced challenges with access to certain raw materials due to macroeconomic factors and several global events such as inflation, geopolitical conflicts and microelectronics shortages. In some cases, these challenges have significantly increased the cost and/or lead time required to obtain certain raw materials. Nonetheless, these challenges have not, to date, materially impacted our ability to perform on our contracts. See “Risk Factors” for further discussion regarding risks related to raw materials.
HUMAN CAPITAL
Underpinned by our values and culture, we hire, promote, and pay based on merit and performance to ensure we have the best team to deliver for our customers. Our focus on technology, innovation and career growth enables us to attract qualified talent, particularly those with security clearances and requisite skills in multiple areas, including science, technology, engineering and math. Our differentiated culture and workforce was a factor in our ability to hire approximately 7,400 new employees in 2024, and as of December 31, 2024, we have approximately 97,000 employees.
Our Values and Culture
Our values reflect our priorities and form the bedrock of our culture:
•We do the right thing - we earn trust, act with ethics, integrity and transparency, treat everyone with respect, value diverse perspectives and foster safe and inclusive environments.
•We do what we promise - we own the delivery of results, focused on quality.
•We commit to shared success - we work together to focus on the mission and take accountability for the sustainable success of our people, customers, shareholders, suppliers and communities.
•We pioneer - with fierce curiosity, dedication and innovation, we seek to solve the world’s most challenging problems.
Among other programs through which the company lives its values, the company maintains a Standards of Business Conduct program through which our employees are empowered to raise concerns through multiple channels without fear of reprisal. In addition to full-time ethics professionals, we also have over 150 business conduct advisors who promote values and an ethical culture within the company. Additionally, our annual Employee Experience Survey gives employees a voice and a mechanism to provide feedback on our culture and empower our leaders to enhance the employee experience. This anonymous survey encourages employee candor on key engagement and inclusion drivers, including belonging, respect, a sense of personal work accomplishment and recommending the company to others. In 2024, 80 percent of employees responded to the survey, an indication that our employees believe their feedback matters. Our performance on the annual survey is compared to the Qualtrics Global Benchmark and our survey results exceeded many of their global norms for both engagement and inclusion. Our leaders review the survey responses and work collaboratively with their teams to take meaningful actions based on survey results.
Our culture and values serve as an enabling force that helps us pioneer, perform and deliver on quality, which results in value for our shareholders, customers, and employees. We actively seek candidates for employment from a wide range of backgrounds and experiences to tap into the full spectrum of talent available now and in the future to create a culture of belonging for everyone.
NORTHROP GRUMMAN CORPORATION
Talent Management
Northrop Grumman’s talent strategy is focused on four key pillars: broadening talent pools; enhancing the employee experience; building leaders of the future; and fostering employee growth. Our strategy addresses the external and internal landscape and ensures that we can attract, retain and develop the workforce necessary to support the continued success of the business.
We hold regular talent review discussions to ensure line of sight to talent at various levels of the organization. We refresh and review succession plans to ensure a robust pipeline of talent and business continuity with a tight linkage to development. We focus on accelerating learning and development of our leaders by providing a combination of experiences, exposure and education.
Our employee development programs strengthen employee skills aligned to our current and future business needs through on-the-job development, knowledge sharing and tools to support career growth. Employees utilize curated, career-specific resources such as My Learning Experience, a machine learning enabled content aggregator that creates a personalized learning experience for each employee. Our Education Assistance Program subsidizes tuition and other educational institution fees to support development through job-related degrees and certificates. Our early-in-career rotation program, Pathways, develops talent pipelines with both depth of critical skills and breadth of experiences. Our technical cohort programs cultivate technical, domain expertise and collaborative thought leadership for early through advanced career levels.
In a rapidly changing world, we maintain focus on keeping our team and our company prepared for the evolving future of work. In addition to offering our employees flexible work arrangements, caregiver support and mental health services that help our employees make their careers work within their lives, we also help our employees build the careers that will serve them into the future. We ensure that our employees have the tools and resources to develop their knowledge base and skill sets, so they can continue to thrive at Northrop Grumman even in the midst of change. When our employees succeed and grow at work, our business succeeds and grows. Through a focus on our employees, we remain agile and innovative, adapting to the future as it unfolds before us.
Employee Health and Safety
Health and safety are foundational to our success. People are our most valuable resource and we prioritize occupational health and safety to position the company for long-term success.
Training and risk and hazard identification, mitigation and prevention are key components of Northrop Grumman’s safety program. Everyone has a responsibility to identify workplace hazards, and employees may raise concerns without fear of reprisal. We evaluate the effectiveness of our health and safety programs by conducting trend analyses of our past performance and externally through benchmarking with industry peers and the U.S. Bureau of Labor Statistics.
Collective Agreements
Approximately 4,100 employees are covered by 15 collective agreements in the U.S., of which we negotiated five renewals in 2024 and expect to negotiate seven renewals in 2025.
See “Risk Factors” for further discussion regarding risks related to our workforce and employee relations.
REGULATORY MATTERS
Government Contract Security Restrictions
We are prohibited by the U.S. government from publicly discussing the details of classified programs. These programs are generally referred to as “restricted” in this Annual Report. The consolidated financial statements and financial information in this Annual Report reflect the operating results of our entire company, including restricted programs.
Contracts
We generate the majority of our business from long-term contracts with the U.S. government for development, production and support activities. Unless otherwise specified in a contract, allowable and allocable costs are billed to contracts with the U.S. government pursuant to the Federal Acquisition Regulation (FAR) and U.S. government Cost Accounting Standards (CAS), which are regulations that govern cost accounting requirements for government contracts. Examples of costs incurred by us and not billed to the U.S. government in accordance with applicable FAR and CAS requirements include, but are not limited to, unallowable employee compensation, charitable donations, interest expense, advertising, and certain legal and travel costs.
We monitor our contracts on a regular basis for compliance with our policies and procedures and applicable government laws and regulations. In addition, costs incurred and allocated to contracts with the U.S. government are routinely audited by the Defense Contract Audit Agency (DCAA).
NORTHROP GRUMMAN CORPORATION
Our long-term contracts typically fall into one of two contract types:
Cost-type contracts - Cost-type contracts include cost plus fixed fee, cost plus award fee and cost plus incentive fee contracts. Cost-type contracts generally provide for reimbursement of a contractor’s allowable costs incurred plus fee. As a result, cost-type contracts have less financial risk associated with unanticipated cost growth but generally provide lower profit margins than fixed-price contracts. Cost-type contracts typically require that the contractor use its best efforts to accomplish the scope of work within some specified time and stated dollar limitation. Fees on cost-type contracts can be fixed in terms of dollar value or can be variable due to award and incentive fees, which are generally based on performance criteria such as cost, schedule, quality and/or technical performance. Award fees are determined and earned based on customer evaluation of the company’s performance against contractual criteria. Incentive fees are generally based on cost or schedule and provide for an initially negotiated fee to be adjusted later, based on the relationship of total allowable costs to total target costs or as schedule milestones are met. Award and incentive fees are included in total estimated sales to the extent it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. We estimate variable consideration as the most likely amount to which we expect to be entitled.
Fixed-price contracts - Firm fixed-price contracts include a specified scope of work for a price that is a pre-determined, negotiated amount and not typically subject to adjustment regardless of costs incurred by the contractor, absent changes by the customer. As a result, fixed-price contracts typically have more financial risk associated with unanticipated cost growth, but provide the opportunity for higher profit margins. Certain fixed-price incentive fee contracts provide for reimbursement of the contractor’s allowable costs plus a fee up to a cost ceiling amount, typically through a cost-sharing ratio that affects profitability. These contracts effectively become firm fixed-price contracts once the cost-share ceiling is reached. Time-and-materials contracts are considered fixed-price contracts as they specify a fixed hourly rate for each labor hour charged.
Profit margins on our contracts may vary materially depending on, among other things, the contract type, contract phase (e.g., development, low-rate production or mature production), negotiated fee arrangements, achievement of performance objectives, unexpected macroeconomic factors or other circumstances, and cost, schedule and technical performance.
See Note 1 to the consolidated financial statements and “Risk Factors” for further information regarding our contracts and Note 15 to the consolidated financial statements for sales by contract type.
The following table summarizes sales for the year ended December 31, 2024, recognized by contract type and customer category:

(1)Sales to the U.S. government include sales from contracts for which we are the prime contractor, as well as those for which we are a subcontractor and the ultimate customer is the U.S. government. Each of the company’s segments derives a substantial percentage of its revenue from the U.S. government.
(2) International sales include sales from contracts for which we are the prime contractor, as well as those for which we are a subcontractor and the ultimate customer is an international customer. These sales include foreign military sales contracted through the U.S. government.
Environmental
Our operations are subject to and affected by federal, state, local and foreign laws, regulations and enforcement actions relating to protection of human health and the environment. We have incurred and expect to continue to incur capital and operating costs to comply with applicable environmental laws and regulations and to achieve our environmental sustainability goals. See “Risk Factors” and Notes 1 and 11 to the consolidated financial statements for further information regarding environmental matters.
Our environmental sustainability goals focus on Northrop Grumman’s facilities in addition to supply chain partners and customers:

ITEM 1A. RISK FACTORS
Item 1A. Risk Factors
Our consolidated financial position, results of operations and cash flows are subject to various risks, many of which are not exclusively within our control, that may cause actual performance to differ materially from historical or projected future performance. We encourage you to consider carefully the risk factors described below in evaluating the information contained in this report as the outcome of one or more of these risks could have a material adverse effect on our financial position, results of operations and/or cash flows.
Industry and Economic Risks
•We depend heavily on a single customer, the U.S. government, for a substantial portion of our business. Changes in this customer’s strategies, priorities and spending could have a material adverse effect on our financial position, results of operations and/or cash flows.
Our primary customer is the U.S. government, from which we derived 87 percent of our sales in 2024; we have a number of large programs with the U.S. Department of the Air Force, in particular. The U.S. government has the ability to delay, modify or cancel ongoing competitions, procurements and programs, as well as to change its future acquisition strategy. We cannot predict the impact on existing, follow-on, replacement or future programs from potential changes in the threat and global security environment, defense spending levels, government and budgetary priorities, political leadership, procurement practices and strategy, inflation and other macroeconomic trends, military strategy; or broader changes in social, economic, security or political demands and priorities.
The U.S. government has the ability to terminate contracts, in whole or in part, for its convenience or for default based on performance. In the event of termination for convenience, contractors are generally protected by provisions covering reimbursement for costs incurred and profit on those costs up to the amount authorized under the contract,
NORTHROP GRUMMAN CORPORATION
but not the anticipated profit that would have been earned. However, to the extent insufficient funds have been appropriated by the U.S. government to cover such costs, the U.S. government may assert that it is not required to provide additional funding for such costs. In the event of termination due to default, contractors may be required to pay for re-procurement costs in excess of the original contract price, net of the value of work accepted from the original contract, as well as other damages. Termination due to our default (or that of a teammate) could have a material adverse effect on our reputation, our ability to compete for other contracts and our financial position, results of operations and/or cash flows.
Where program cost estimates exceed certain thresholds, our customer has been, and may in the future be, required to provide congressional notification of significant or critical cost increases (or breaches) under the Nunn-McCurdy Act, which, in some circumstances, could result in program restructure or termination. For example, in January 2024 the customer provided congressional notification that the Sentinel program (formerly called the Ground Based Strategic Deterrent program) was under a Nunn-McCurdy breach review, which was completed in July 2024, resulting in the certification for continuance of the program.
The U.S. government also has the ability to stop work under a contract for a limited period of time for its convenience. The U.S. government has invoked and could invoke this ability across a limited or broad number of contracts. In the event of a stop work order, contractors are typically protected by provisions covering reimbursement for costs incurred to date and for costs associated with the temporary stoppage of work plus a reasonable fee. However, such temporary stoppages often introduce inefficiencies and result in financial and other damages for which contractors may not be able to negotiate full recovery. In some cases, they have also ultimately resulted and could result in termination of a contract for convenience or reduced future orders.
•Significant delays or reductions in appropriations for our programs or U.S. government funding more broadly, including a prolonged continuing resolution, government shutdown or breach of the debt ceiling, and future budget and program decisions can negatively impact our business and programs and could have a material adverse effect on our financial position, results of operations and/or cash flows.
U.S. government programs are subject to annual congressional budget authorization and appropriation processes. For many programs, Congress appropriates funds annually even though the program performance period may extend over several years. Programs are often partially funded initially, with additional funds committed only as Congress makes further appropriations. When we or our subcontractors incur costs in excess of funds obligated on a contract, we are generally at risk for reimbursement unless and until additional funds are obligated to the contract. We cannot predict what funding will ultimately be approved for individual programs. In addition, pressures on, as well as laws and plans relating to the federal budget, potential changes in priorities and defense spending, the timing and substance of the appropriations process, use of continuing resolutions (with restrictions, e.g., on new contract and program starts) and the federal debt limit (including a breach of the federal debt ceiling), have adversely affected and could adversely affect the amount and timing of funding for individual programs and delay purchasing or payments by our customers. In the event government funding for our significant programs is reduced, delayed or unavailable, or orders are reduced, our contracts or subcontracts, or competitions for such programs have at times been, and in the future may be, terminated or changed.
The U.S. continues to face a changing geopolitical environment, along with substantial fiscal, economic and security challenges, which affect funding and budgetary priorities. The budget and macroeconomic environment, global security environment, political instability, and uncertainty surrounding the appropriations processes and the debt ceiling, remain significant short and long-term risks. See “Overview” in MD&A. In addition, high deficit levels and high debt servicing costs could drive cuts to federal spending. Considerable uncertainty exists regarding how future budget and program decisions will unfold. If annual appropriations bills are not timely enacted, the U.S. government may continue to operate under a continuing resolution (potentially of extended duration), restricting new contract or program starts, presenting resource allocation challenges and placing limitations on budgets. We also may face a prolonged government shutdown that could lead to program cancellations, disruptions and/or stop work orders and could limit the U.S. government’s ability to progress programs and make timely payments. A prolonged shutdown could limit our ability to perform on our contracts and successfully compete for new work. If the statutory debt limit is not increased adequately, we could be obligated to work without receiving timely payments, and a prolonged breach could have far-reaching adverse consequences. If the macroeconomic environment deteriorates, including due to rising inflation or other causes, we could experience labor and supply chain challenges and increased costs and existing or anticipated appropriated and contracted funds may not be sufficient to cover costs incurred on existing or future programs.
NORTHROP GRUMMAN CORPORATION
Future funding for certain programs in which we participate may be reduced, delayed or cancelled. Budget cuts globally could adversely affect the viability of our subcontractors and suppliers. While we believe that our business is well-positioned in areas for future defense spending, changing priorities, budget pressures, defense spending cuts, challenges in the appropriations process, the possibility of a long-term continuing resolution (or series of continuing resolutions) and breach of the debt ceiling, ongoing fiscal debates and the global economic and security environment increase uncertainties and risk.
•We use estimates when accounting for contracts. Contract cost growth or changes in estimated contract revenues and costs can affect our profitability and could have a material adverse effect on our financial position, results of operations and/or cash flows.
Contract accounting requires judgment, including in assessing risks, estimating contract revenues and costs, and predicting future performance. Given the size and nature of our many contracts, estimating total revenues and costs at completion is complex and subject to many variables. When there is sufficient information to assess expected future performance, we consider performance related incentives, awards and penalties in estimating revenue and profit rates. Suppliers’ expected performance, and the availability and costs of labor, materials and components, are also considered.
Our operating income can be adversely affected when estimated contract costs increase, especially without comparable increases in revenue. There are many reasons estimated contract costs can increase, including inflation, labor challenges, supply chain challenges, and market and exchange rate volatility; delays or limitations in customer funding; design or other development challenges; production challenges (including from technical or quality issues and other performance concerns); inability to realize learning curves or other cost savings; changes in laws or regulations; actions necessary for long-term customer satisfaction; and natural disasters or environmental matters.
We aim to mitigate this risk through contract terms, and we have submitted and may submit requests for equitable adjustment (REAs), engineering change proposals or other claims to seek recovery in whole or in part for our increased costs. We have also sought, and will seek, other avenues, as appropriate, to compensate the company for certain unexpected cost increases. However, our contracts may not enable full recovery, and/or customers may disagree with our requests or may not have funding to cover them.
Our risk varies with the type of contract. Fixed-price contracts inherently tend to have more financial risk than cost-type contracts, including as a result of inflationary pressures, labor rates and shortages, challenges in estimating contract revenues and costs and supplier challenges. In 2024, approximately half of our sales were derived from fixed-price contracts. We have more often entered into fixed-price contracts where costs can be more reasonably estimated based on actual experience, such as for mature production programs. However, our customers have sought, and may in the future seek, fixed-price contracts for development programs, combined development and production programs, or low-rate initial production programs, where the risks are greater. For example, such contracts can create performance and financial risks, whether due to the estimates of costs required to complete such contracts being subject to potentially significant variability or because of the challenge of starting and stabilizing manufacturing production and test lines while concurrently validating final design and managing changes in requirements or capabilities requested by the customer. In addition, our contracts contain provisions relating to cost controls and audit rights. If we do not achieve our estimates or meet terms in our contracts, our profitability has at times been and may be reduced, and we have incurred and may incur losses.
Certain of our fixed-price contracts include or may include fixed-price development work. This work is inherently more uncertain, and, as a result, there is typically more variability in estimates of the costs to complete the development stage. As work progresses into production, the risks associated with estimating total costs are typically reduced as compared to fixed-price development work. While management uses its best judgment to estimate costs associated with fixed-price contracts, future events can result in significant adjustments. In addition, from time to time, we may begin performing on a contract prior to completing contract negotiations. Uncertainties in final contract terms, quantity and pricing, or loss of negotiating leverage associated with long delays could negatively affect our profitability. Certain of our contracts also include options exercisable at the customer’s discretion. The customer may decline to exercise an option, or the customer may exercise an option for which we may incur a loss or perform at a low margin, either of which could adversely affect our results of operations.
Under cost-type contracts, allowable costs are generally subject to reimbursement plus a fee. We often enter into cost-type contracts for development programs with complex design and technical challenges. These cost-type programs may have award or incentive fees that are uncertain and may be earned over extended periods or towards the end of the contract. In these cases, the financial risks are typically in recognizing profit, which ultimately may not be earned, or program cancellation if cost, schedule, or technical performance issues arise. We also face
NORTHROP GRUMMAN CORPORATION
additional financial risk when solicitations require us to bid on cost-type development work and fixed-price production lots and/or options in one submission, where we must estimate the cost of production before a product has been developed and tested, or cost-type development work requiring us to provide certain items at our expense or with little or no fee. Macroeconomic challenges increase these risks.
Because of the significance of management’s judgments and the estimation processes, and the difficulties inherent in estimating future costs, particularly in a challenging macroeconomic environment, it is possible that we could see materially different results. Changes in underlying assumptions, circumstances or estimates, and the failure to recover on requests for equitable adjustments, engineering change proposals or other claims could have a material adverse effect on the profitability of one or more of our contracts and on our overall financial position, results of operations and/or cash flows. See “Critical Accounting Policies and Estimates” in MD&A and Note 11 to the consolidated financial statements.
•Competition within our markets and bid protests, or other attempts to interfere with our ability to obtain and retain awards, may affect our ability to win new contracts and result in reduced revenues, which could have a material adverse effect on our financial position, results of operations and/or cash flows.
We operate in highly competitive markets and our competitors may have more financial capacity or more extensive or specialized engineering, technical, manufacturing, marketing or servicing capabilities. They may be willing to accept more risk or lower profitability in competing for contracts. We have seen, and anticipate we will continue to see, increased competition in some of our core markets, especially as a result of our customers’ budget pressures, their focus on affordability and competition, and our own success in winning business. We are facing increasing competition in the U.S. and outside the U.S. from U.S., foreign and multinational firms, including new entrants, and anticipate that mergers or acquisitions within our industry could further increase competition or could limit our access to certain suppliers without appropriate remedies to protect our interests. We are also facing increasing competition for, and more limited access to various critical products, services and other supplies. In some instances, foreign companies may receive loans, subsidies and other assistance from their governments that may not be available to U.S. companies and foreign companies may be subject to fewer restrictions on technology transfer. For some products and services, some customers, including the DoD, are turning to commercial contractors, newer entrants to markets and non-traditional defense contractors, which may have lower cost or more agile operating structures and the ability to leverage changes in customer acquisition strategies (e.g., multiple awardees, short lifecycles). In addition, some customers continue to utilize small business contractors or determine to source work internally. Our success in competing depends, in part, on our ability to remain cost-competitive, respond to changes in customer acquisition strategies, accurately anticipate our customers’ needs and successfully effect our digital transformation strategy and adopt and integrate new digital technologies into our manufacturing, operations, and products and services.
In addition, U.S. government procurement laws permit certain legal challenges to the terms of a contract solicitation or award, referred to as a bid protest. Bid protests can result in award decisions being reversed and loss of the contract award. Even where a bid protest does not result in such a loss, it can result in significant expenses and delay the start of contract activities and revenue or result in contract modifications. We are also subject to risks associated with our ability to challenge Other Transaction Authority (OTA) agreements, which the U.S. government can award for certain research, prototype and production projects. OTA awards are not subject to all of the procurement requirements that typically apply to DoD contracts and rights to protest such awards may be more limited than for other contracts.
•The global macroeconomic environment has negatively impacted and could in the future negatively impact our business, and if we are unable to mitigate such challenges, it could have a material adverse effect on our financial position, results of operations and/or cash flows.
Our business, financial position, results of operations and/or cash flows have been and may in the future be adversely impacted by the global macroeconomic environment, which impacts have included and may in the future include high rates of inflation; increased interest rates; tight credit in financial markets; widespread disruptions in supply chains; workforce challenges, including labor shortages; and market volatility, including exchange rate volatility. These and other macroeconomic challenges have led and can lead to increased costs, labor and supply shortages, and delays and disruption in performance, as well as competing demands for scarce resources, which in turn have adversely impacted and may continue to adversely impact our customers, our industry, our company, our suppliers and others with whom we do business. We continue to work proactively to mitigate the challenges caused by the macroeconomic environment, including, in some cases, seeking the inclusion of economic price adjustment clauses or seeking to recover on requests for equitable adjustments, engineering change proposals or other claims.
NORTHROP GRUMMAN CORPORATION
Legal and Regulatory Risks
•We are subject to various investigations, claims, disputes, enforcement actions, litigation, and other legal proceedings that could ultimately be resolved against us and could have a material adverse effect on our financial position, results of operations and/or cash flows.
The size, nature and complexity of our business make us particularly susceptible to investigations, claims, disputes, enforcement actions, prosecutions, litigation and other legal proceedings (collectively “legal proceedings”), particularly those involving governments, which may continue to increase. We are or may become subject to legal proceedings globally (including criminal, civil and administrative) and across a broad array of matters, including, but not limited to, government contracts, cost accounting, financial accounting and reporting, false statements or claims, cybersecurity and pension accounting and other employee benefit plan matters. These matters can divert resources; result in administrative, civil or criminal fines, penalties or other sanctions (including judgments, convictions, consent or other voluntary decrees or agreements), compensatory, treble or other damages, non-monetary relief, or other liabilities; and otherwise harm our business and our ability to obtain and retain awards. Certain outcomes may lead to suspension or debarment from government contracts or suspension of export/import privileges for the company or one or more of its components. Suspension or debarment or criminal resolutions in particular could have a material adverse effect on the company because of our reliance on government contracts and export authorizations. Legal proceedings, even if pending or not ultimately resulting in adverse action, or if fully indemnified or insured, can negatively impact our reputation among our customers and the public, and make it substantially more difficult for us to compete effectively for business, obtain and retain awards, ensure adequate funding for our programs or obtain adequate insurance in the future. See Note 10 to the consolidated financial statements for information regarding the company’s investigations, claims and litigation.
•As a U.S. government contractor, we and our partners are subject to various procurement and other laws, regulations and contract terms applicable to our industry, as well as those more broadly applicable to industry, and changes in such laws, regulations or terms, any negative findings by the U.S. government as to our or our partners’ compliance with them, and changes in our customers’ business practices globally could affect our ability to compete and have a material adverse effect on our financial position, results of operations and/or cash flows.
U.S. government contractors (including their subcontractors and others with whom they do business) must comply with various specific procurement laws, regulations, rules and other legal requirements, as well as ones more broadly applicable. These various legal requirements, although sometimes customary in government contracting, increase costs and risks. They have been and are evolving at a significant pace. The costs are not always fully recoverable. New laws or other requirements, or changes to existing ones (including, for example, related to cybersecurity, information and data protection, cost accounting, environment, sustainability, securities, competition, compensation costs, taxes, counterfeit parts, pensions, and use of certain non-US equipment) or more expansive interpretations or other changes in how government agencies construe existing ones, can significantly increase our costs and risks and reduce our profitability.
We operate in a highly regulated environment and are routinely audited and reviewed by the U.S. government and its agencies, such as the DCAA, Defense Contract Management Agency (DCMA) and the DoD Inspector General. These agencies review performance under our contracts, our cost structure and accounting, our compliance, and the adequacy of our systems in meeting government requirements. Costs ultimately found to be unallowable or improperly allocated are generally not reimbursed or require us to refund the customer. When an audit uncovers improper or illegal activities, we are subject to possible civil and criminal penalties, sanctions, or suspension or debarment. Whether or not illegal activities are alleged, the U.S. government has the ability to decrease or withhold certain payments when it deems systems to be inadequate, with significant financial impact, regardless of the ultimate outcome. In addition, we risk serious reputational harm in situations involving allegations of impropriety made against us or our business partners.
Our industry has experienced, and we expect it will continue to experience, significant changes to business practices globally, in part as a result of changes in the global security and threat environment and an increased focus on affordability, efficiencies, business systems, recovery of costs and a reprioritization of available defense funds. We have experienced and may continue to experience an increased number of audits and challenges to our claims and our business systems for current and past years, as well as longer periods to close audits, broader requests for information and an increased risk of withholdings of payments. The U.S. government has been pursuing and may continue to pursue policies that could negatively impact our profitability, including those that shift additional responsibility and performance risks to the contractor. Changes in procurement practices, including those favoring
NORTHROP GRUMMAN CORPORATION
incentive-based fee arrangements; fixed price development or long-term production programs; different award criteria; and non-traditional contract provisions have affected and may in the future affect our profitability and predictability.
We (including our subcontractors and others with whom we do business) also are subject to, and expected to perform in compliance with, a vast array of federal, state and local laws, regulations, contract terms and requirements related to our industry, our products and the businesses we operate, as well as those more broadly applicable to industry, such as securities laws and regulations. These requirements, whether specific to our industry or broadly applicable, can limit our ability to achieve our goals. If we are found to have violated any such requirements, or are found not to have acted responsibly, we may be subject to a wide array of actions, including contract modifications or termination; payment withholds; the loss of export/import privileges; administrative, civil or criminal judgments or penalties (including convictions, agreements, fines, damages and non-monetary relief); or suspension or debarment.
•The improper conduct of employees, agents, subcontractors, suppliers, business partners or joint ventures in which we participate can impact our reputation and our ability to do business, which could have a material adverse effect on our financial position, results of operations and/or cash flows.
We face potential liability based on misconduct by employees, agents or others working with us or on our behalf that could violate the applicable laws of the jurisdictions in which we operate, including laws governing improper payments to government officials, the protection of export controlled or classified information, false claims, procurement integrity, cost accounting and billing, competition, information security and data privacy, intellectual property and contract terms. Improper actions by our employees, agents or others working with us or on our behalf also subject us to risk of administrative, civil or criminal investigations and enforcement actions; monetary and non-monetary penalties; liabilities; and the loss of privileges and other sanctions, including suspension and debarment. We have in the past experienced and may in the future experience misconduct committed by our employees, agents, suppliers, partners or others working with us or on our behalf. This risk of improper conduct increases as we continue to expand globally, with greater opportunities and demands to do more business with local and new partners, and in new environments. At the same time, law enforcement agencies are continuing to focus collaboratively on combating global corruption and other misconduct. In the ordinary course we form and are members of joint ventures or other business arrangements and/or invest in third parties with whom we do business. We may be unable to prevent misconduct or violations of applicable laws by these joint ventures or our partners, including, in each case, their respective officers, directors and employees.
•Environmental matters, including climate change, unforeseen costs associated with compliance and remediation efforts, and government and third-party claims, could have a material adverse effect on our reputation and our financial position, results of operations and/or cash flows.
Our operations are subject to and affected by a variety of federal, state, local and foreign environmental laws and regulations, including as they may be expanded, otherwise changed or enforced differently over time. Compliance with these existing and evolving environmental laws and regulations requires, and is expected to continue to require, significant operating and capital costs. For example, some of these recently enacted laws and regulations prohibit the use of certain chemicals or other substances that are used in our business, which has, in some cases, required us to identify alternate sources, resulting in additional costs and/or otherwise impacting our business and operations. New and evolving laws, regulations and rule makings globally impose different and at times more restrictive standards and require greater disclosures. For example, certain jurisdictions, including the State of California and the European Union, have enacted legislation which requires or would require more stringent greenhouse gas emissions and climate risk reporting. They could also require capital investments, could adversely impact our ongoing operations, and could require changes on a more accelerated time frame. We expect our suppliers to face similar challenges and incur additional compliance costs that may be passed on to us. These direct and indirect costs can adversely impact our results of operations and financial condition, and, if we are unable to comply with legislative and regulatory requirements or meet our sustainability objectives, our reputation and ability to do business could be negatively impacted. In addition, our customers’ requirements, priorities and ways of doing business with respect to environmental matters, and climate change specifically, also may have an impact on our business, operations and financial success.
Environmental matters may significantly impact our business and operations and present evolving risks and challenges. Environmental impacts, including climate change specifically, create short and long-term financial risks to our business globally. We have significant operations located in regions that have been, and may in the future be, exposed to significant weather events and other natural disasters. Increased worldwide focus on climate change has
NORTHROP GRUMMAN CORPORATION
led to legislative and regulatory efforts to combat both potential causes and adverse impacts of climate change, including regulation of greenhouse gas emissions. New or more stringent laws and regulations related to greenhouse gas emissions and other climate change related concerns have affected and will likely continue to affect us, our suppliers and our customers. The company has set a goal to achieve net zero greenhouse gas emissions in our operations by 2035 and is committed to working to achieve its climate change and other sustainability goals. We are working to identify opportunities to utilize alternatives to fossil-based energy sources, to decrease our greenhouse gas emissions, to reduce our consumption of water and generation of waste, and to ensure our compliance with environmental regulations where we operate, enhancing our record of environmental sustainability. However, the costs of doing so may be greater than expected, which could affect our ability to achieve our goals.
We may be subject to substantial administrative, civil or criminal fines, penalties or other sanctions (including suspension, debarment or disqualification) for violations of environmental laws. If we are found to be in violation of the Federal Clean Air Act or the Clean Water Act, the facility or facilities involved in the violation could be placed by the Environmental Protection Agency on a list of facilities that generally cannot be used in performing on U.S. government contracts until the violation is corrected.
We incur, and expect to continue to incur, substantial remediation costs related to the cleanup of pollutants previously released into the environment. Stricter or different remediation standards or enforcement of existing laws and regulations; new requirements, including regulation of new substances; discovery of previously unknown or more extensive contamination or new contaminants; imposition of fines, penalties, or damages (including natural resource damages); a determination that certain remediation or other costs are unallowable; rulings on allocation or insurance coverage; and/or the insolvency, inability or unwillingness of other parties to pay their share, could require us to incur material additional costs in excess of those anticipated.
We are and may become a party to various legal proceedings and disputes involving government and private parties (including individual and class actions) relating to alleged impacts from pollutants released into the environment, including bodily injury and property damage. For example, please see Note 10 for a discussion of certain disputes and lawsuits related to legacy Bethpage environmental conditions. These matters could result in material compensatory or other damages, remediation costs, penalties, and non-monetary relief, and adverse determinations on allowability or insurance coverage.
Government and private parties also seek to hold us responsible for liabilities or obligations related to former operations that have been divested or spun-off and/or for which we believe other parties have agreed to be responsible and/or to indemnify us. These rights may not be sufficient to protect us.
•Unanticipated changes in our tax provisions or an increase in our tax liabilities, whether due to changes in applicable laws and regulations, the interpretation or application thereof, or a final determination of tax audits or litigation or agreements, could have a material adverse effect on our financial position, results of operations and/or cash flows.
We are subject to income and other taxes in the U.S. and foreign jurisdictions. Changes in applicable tax laws and regulations, or their interpretation and application, including the possibility of retroactive effect, have affected and could affect our tax expense. In addition, the final determination of any tax audits or related litigation, in particular with regard to our positions on research credits, could be materially different from our historical income tax provisions and accruals. In addition, we may be subject to future tax audits and legal challenges involving OATK, which we acquired in 2018, or the spinoff of its then subsidiary Vista Outdoor, and we may be unable to obtain indemnification or we may be required to indemnify Vista.
•Cyber and other security threats or disruptions could have a material adverse effect on our reputation and our financial position, results of operations and/or cash flows.
As a defense contractor, we face significant cyber and other security threats. They include, among other things, attempts to gain unauthorized access to sensitive information or otherwise compromise the integrity, confidentiality and/or availability of our systems, hardware and networks, and the information on them; insider threats; ransomware; threats to the safety of our directors, officers and employees; threats to our facilities, infrastructure, products (we produce and use), and subcontractors or other suppliers (referred to inclusively as suppliers); and threats from terrorist acts, espionage, civil unrest and other acts of aggression. We are also subject to increasing government, customer and other cyber and security requirements, including disclosure obligations.
Cyber threats, both on premises and in the cloud, are complex, continuous and evolving and include, but are not limited to: malicious software, destructive malware, ransomware, targeting by more advanced and persistent
NORTHROP GRUMMAN CORPORATION
adversaries, including nation states and other actors, zero-day attacks, attempts to gain unauthorized access to systems or data, disruption to operations, critical systems or denial of service attacks; unauthorized release of confidential, personal or other protected information (ours or that of our employees, customers or partners); corruption of data, networks or systems; harm to individuals; and loss of assets. We have been and could be impacted by cyber threats or other disruptions or vulnerabilities found in products or services we use or in our internal, partners’ or customers’ systems that are used in connection with our business. Further, the sophistication, availability and use of artificial intelligence by threat actors present an increased level of risk. We have experienced cyber attacks and, due to the evolving threat landscape, expect we will continue to experience additional attacks in the future. The various measures and controls we have implemented to monitor and mitigate risks associated with these threats and to increase the cyber resiliency of our infrastructure and products may not always be sufficient or fully effective, particularly against previously unknown vulnerabilities, including those that could go undetected for an extended period.
Cyber events have caused and could cause us harm and require us to undertake remedial actions. Successful attacks can lead to losses or misuse of sensitive information or capabilities; theft or corruption of data; harm to personnel, infrastructure or products; protracted disruptions in our operations and performance; and the misuse of our products. They can also damage our reputation, impact our ability to obtain adequate insurance coverage, and lead to loss of business, regulatory actions, and costs, liabilities or other financial losses for which we may not have adequate sources of recovery.
Our customers and partners (including our suppliers and joint ventures) to whom we entrust confidential data, and on whom we rely to provide products and services, face similar threats and growing requirements, including ones for which others may seek to hold us responsible. We depend on our customers, suppliers, and other business partners to implement and verify adequate controls and safeguards to protect against and report cyber incidents. If they fail to deter, detect, remediate or report cyber incidents in a timely manner, we may suffer financial and other harm, including to our information, operations, performance, employees and reputation. Further, the systems, products and services that we provide to customers may not be able to detect or deter threats, or effectively to mitigate resulting losses. These losses could adversely affect our customers and our company.
We also face increasing and evolving disclosure obligations related to cyber and other security events and the risk of failing to meet all our existing or future disclosure obligations and/or having our disclosures misinterpreted. National security or public safety considerations may also affect, or in limited instances prevent, our public disclosure of a cybersecurity incident in certain circumstances.
We also face threats to our physical security, including to our facilities and the safety and well-being of our people, including senior executives. These threats could involve terrorism, insider threats, targeted threats against senior executives, workplace violence, civil unrest, natural disasters, damaging weather or fires, which could adversely affect our company. Our customers and suppliers face similar risks that, if realized, could also adversely impact our operations. Such acts could cause delays, manufacturing downtime, or other impacts that could detrimentally impact our ability to perform our operations. We could also incur unanticipated costs to remediate impacts and lost business. For further discussion of our cybersecurity risk management, strategy and governance, see “Cybersecurity.”
•Our earnings and profitability depend, in part, on subcontractor and supplier performance, financial viability, and compliance with regulatory requirements globally, as well as highly skilled labor, raw materials, chemicals, parts, and component availability and pricing, and one or more of these factors could have a material adverse effect on our financial position, results of operations and/or cash flows.
We rely on other companies to provide raw materials, chemicals, parts and components and subsystems for our products, produce hardware elements and sub-assemblies, provide software and intellectual property, provide information about the parts they supply to us, and perform some of the services we need for our operations or provide to our customers, and to do so in compliance with all applicable laws, regulations and contract terms, while maintaining strong values and cultures. Disruptions or performance problems with our subcontractors or other suppliers (referred to inclusively as suppliers), unanticipated cost growth for the products and services they provide, failure to meet regulatory or contractual requirements, unethical or illegal behavior, or a misalignment between our contractual obligations to our customers and our agreements with our suppliers, have had and may continue to have various adverse impacts on the company, including on our ability to meet our commitments to customers and financial expectations. This risk of delays and disruptions in the supply chain, and supply chain challenges more broadly, has been and continues to be heightened globally due to the current macroeconomic environment.
NORTHROP GRUMMAN CORPORATION
Our ability to perform our obligations on time is adversely affected if one or more of our suppliers is unable to provide the agreed-upon products, materials or information, or perform the agreed-upon services in a timely, compliant and cost-effective manner. We also may experience challenges performing if we are unable to use certain raw materials, chemicals or other substances due to laws or other regulations that restrict or prohibit the use of such items or cause suppliers to be unwilling or unable to supply them and we cannot obtain a reasonable substitute on a cost-effective basis. Changes in political or economic conditions, including changes in demand, changes in the macroeconomic environment (including inflation and labor and supply chain challenges), changes in defense budgets and/or priorities, changes in the global security environment, changes in export/import restrictions, sanctions and other trade restrictive activities, evolving requirements, or changes in access to critical technology and materials (including metals and components), among others, have adversely affected and could in the future adversely affect the financial stability of our suppliers and/or their ability to perform effectively. The inability of our suppliers to perform effectively has required and may require us to provide them additional support and/or to transition to alternate suppliers, if available, with additional costs and delays. We expect we will need to continue to provide additional resources to support certain of our suppliers in performing under our contracts. In addition, if we are unable to do that or if our suppliers are no longer able to perform due to financial difficulties, we may face additional losses and liabilities under our current contracts and adversely impact the prospects for certain new ones.
In connection with our U.S. government contracts, we are required to procure certain materials, components and parts from supply sources approved by the customer and/or are restricted from procuring products or services from certain sources. For example, we require assured access to certain microelectronics. Our ability to produce and/or deliver products will be significantly impacted if the microelectronics manufacturing supply chain is cut off or significantly delayed. For some components, there has been or may be only one supplier, or one domestic supplier. If that supplier cannot meet our needs or if we are unable to procure components from certain suppliers due to regulatory restrictions, we may be unable to find a suitable alternative and to meet our obligations.
We and our suppliers are also facing increased legal requirements globally. We may be held responsible not only for our compliance, but that of our suppliers. Our procurement practices are intended to reduce the risk we procure counterfeit, unauthorized or otherwise non-compliant parts or materials. We rely on our suppliers also to comply with applicable laws, customer requirements and contract terms, to ensure the quality of their components and effectively to mitigate the risk of cyber and security threats or other disruptions to their performance.
•If we are unable to attract and retain a qualified workforce necessary for our business, we may be unable to maintain our competitive position, meet the needs of our customers or achieve our results, which could have a material adverse effect on our financial position, results of operations and/or cash flows.
Our operating results and growth opportunities are heavily dependent upon our ability to attract and retain sufficient qualified personnel who are or can reasonably be cleared (and obtain program access), who have the requisite skills in multiple areas, including science, technology, engineering and math, and who share our values and are able to operate effectively consistent with our culture. Outside the U.S., it is increasingly important that we are also able to attract and retain personnel with relevant local qualifications and experience. We continue to face increased competition for talent with traditional defense companies, new entrants in our markets and commercial companies, globally, with increasing wage rates and, in some cases, greater flexibility around working conditions. Although we have realized benefits from extensive hiring and retention programs in recent years, the risk of insufficient personnel may increase, either broadly or with respect to select critical staffing requirements, including those with security clearances. If necessary qualified personnel are more scarce or more difficult to attract or retain under reasonable terms, or if we experience a high level of attrition, generally or in particular areas, or if such personnel are increasingly unable to obtain security clearances or program access on a timely basis or are unable to be timely and effectively trained, we would expect higher labor-related costs and we could face challenges performing on various of our programs and meeting financial expectations. In addition, the macroeconomic environment, including continued challenges in the global labor market, may further affect our ability to hire, develop and retain the necessary workforce, and to maintain performance levels and our corporate culture.
Certain of our employees are covered by collective agreements. We generally have been able to renegotiate renewals to expiring agreements without significant disruption of operating activities. However, other companies recently have experienced challenges in renewing labor agreements. If, for example, we also experience difficulties with renewals and renegotiations of existing collective agreements, or if our employees pursue new collective representation, we could incur additional expenses and impacts on operating efficiency and may be subject to work stoppages or other labor-related disruptions. Any such expenses or delays could adversely affect our performance and results.
NORTHROP GRUMMAN CORPORATION
•Our international business exposes us to additional risks, including risks related to geopolitical and economic factors, laws and regulations, which could have a material adverse impact on our financial position, results of operations and/or cash flows.
Sales to customers outside the U.S. are an important component of our strategy. Our international business (including our participation in joint ventures and other forms of collaboration, requirements for local content, and our global supply chain) is subject to numerous political and economic factors, legal requirements, cross-cultural considerations and other risks associated with doing business globally. These risks differ in some respects from those associated with our U.S. business and our exposure to such risks is expected to increase if and as our international business continues to grow.
Our international business is generally subject to both U.S. and foreign laws, regulations and practices. Failure by us, our employees, partners or others with whom we work to comply with applicable laws and regulations could result in administrative, civil, commercial or criminal liabilities, including suspension or debarment from government contracts or suspension of export/import privileges. Failure to comply with local practices can adversely impact our ability to win and perform business. New regulations and requirements, or changes to existing ones in countries in which we operate can significantly increase our costs and risks of doing business internationally. Our customers outside of the U.S. also often have the ability to terminate contracts for convenience as well as for default based on performance. Suspension or debarment, or termination of a contract due to default could have a material adverse effect on our reputation, our ability to compete for other contracts and our financial position, results of operations and/or cash flows. We also face risks related to the unintended or unauthorized use of our products and resources.
Changes in laws, political leadership and environment, and/or security risks may dramatically affect our ability to conduct or continue to conduct business in international markets. Our international business is impacted by changes in U.S. and non-U.S. national policies and priorities, and geopolitical relationships, any of which may be influenced by changes in the global threat environment, political leadership, geopolitical and economic uncertainties, world events, government budgets, inflationary pressures, sanctions imposed in countries where we do business or seek to do business, and economic and political factors more generally. The U.S. and its allies and security partners continue to face a global security environment of heightened tensions and instability, threats from state and non-state actors, including major global powers, as well as terrorist organizations, emerging nuclear tensions, and diverse regional security concerns. These factors have impacted and may in the future impact demand for our products and services, the competitive position of our products and services, funding for programs, our ability to perform, our supply chain, export authorizations, purchasing decisions or customer payments. Global macroeconomic conditions, as well as fluctuations in foreign currency exchange rates and credit, are also likely to further impact our business.
Our contracts with non-U.S. customers in some cases include terms and reflect legal requirements that create additional risks. Terms include requirements to hire, invest, manufacture or purchase locally, or specific financial obligations, including offset obligations, and provisions that impose significant penalties if we fail to meet such requirements. We have also been required to enter into letters of credit, performance bonds, bank guarantees or other financial arrangements in certain cases. If we are dependent on certain suppliers, as in the U.S., we face risks related to their failure to perform in accordance with legal requirements, particularly where we rely on a sole source supplier. Our ability to sell products globally could be adversely affected if we are unable to design our products on a cost effective basis or to obtain and retain all necessary export authorizations, which the U.S. government can deny, change or revoke for reasons outside our control. Our business outside of the U.S. also depends on our ability to attract and retain sufficient qualified personnel with the skills and/or security clearances in the markets in which we do business. We also partner with non-U.S. companies, including through joint ventures and other forms of collaboration, which subjects us to risks related to the ability to identify and negotiate appropriate arrangements with qualified and acceptable local partners, potential exposure for their actions, and the ability effectively to terminate these arrangements. Such risks are complicated further when we partner with government-affiliated entities.
The products and services we provide, including those provided by suppliers and joint ventures, are sometimes in countries with unstable governments, economic or fiscal challenges, military or political conflicts, different business practices and/or developing legal systems. This may increase the risk to our employees, suppliers or other third parties, including for their safety, and increase our risk to a wide range of financial consequences and other liabilities, as well as loss of property or damage to our products.
•Our business is subject to significant disruptions caused by natural disasters or other events outside of our control, which could have a material adverse effect on our financial position, results of operations and/or cash flows.
NORTHROP GRUMMAN CORPORATION
We have significant operations, including centers of excellence, located in regions that have been, and may in the future be, exposed to hurricanes, earthquakes, water levels, wildfires, windstorms, heat waves, other extreme weather conditions, acts of terrorism, power shortages and blackouts, telecommunications failures and other significant disruptions, and epidemics, pandemics, and similar outbreaks, especially of infectious diseases. We expect our facilities, operations, employees and communities in the future, particularly at facilities prone to extreme weather events, such as in Florida and California, to continue to be at risk for future natural disasters or other weather events (which may be exacerbated by climate change). Climate related changes can impact natural disasters, including weather patterns, with the increased frequency and severity of significant weather events (e.g., flooding, hurricanes and tropical storms), natural hazards (e.g., increased wildfire risk), rising mean temperature and sea levels, and long-term changes in precipitation patterns (e.g., drought, desertification, water scarcity and/or poor water quality).
Such natural disasters and other significant disruptions can interrupt our operations, impact our employees, and result in significant costs and adversely affect our performance. Our subcontractors and other suppliers have also been, and may in the future be, subject to natural disasters or other significant disruptions that could affect their ability to deliver or perform. Disruptions also impact the availability and cost of materials needed for manufacturing and can increase insurance and other operating costs, or result in a lack of available coverage. Although we take steps to mitigate these risks, including considering them in determining where to put new businesses, the damage and adverse effects of natural disasters and other significant disruptions, which may increase, as well as delays in recovery, may be significant.
•Our future success depends, in part, on our ability to innovate, develop new products and technologies, progress and benefit from digital transformation and maintain technologies, facilities and equipment to win new competitions and meet the needs of our customers. Failure to do so or meet our contractual obligations that require innovative design could adversely affect our profitability, reputation and future prospects and have a material adverse effect on our financial condition, results of operations and/or cash flows.
We design, develop and manufacture technologically advanced and innovative products and services, which are applied by our customers in a variety of environments, including highly demanding operating conditions, to accomplish challenging missions. Our success depends upon our ability to develop technologically advanced, innovative and cost-effective products and services and market these products and services to our customers globally. Our ability to develop innovative and technologically advanced products depends on the talent of our workforce, continued funding for, and investment in, research and development projects, continued access to assured suppliers of important technologies and components, our ability to compete (including with commercial companies) and our ability to provide the people, technologies, facilities, equipment and financial capacity needed to develop and deliver those products and services with maximum efficiency. To perform on our contracts and to win new business, we also depend increasingly on our ability to progress successfully on our digital transformation strategy. To meet evolving customer requirements, it is increasingly necessary to differentiate our offerings and to achieve efficiencies in our operations through digital based solutions. If we are unable to continue to develop new products and technologies in a timely fashion, and progress successfully to effect digital solutions and transformation, or if we fail to achieve market acceptance more rapidly than our competitors, we may be unable to maintain our competitive position and our future success could be materially adversely affected.
We aim to ensure that our technical solutions are responsibly developed, tested and operated. Problems and delays in the successful development and delivery of our solutions, including as a result of issues with design, technology or operations, digital transformation, inability to achieve learning curve assumptions, artificial intelligence, manufacturing materials or components, or subcontractor (or other supplier) performance can prevent us from meeting requirements and create significant risk and liabilities. Similarly, failures to perform on schedule or otherwise to fulfill our contractual obligations can negatively impact our financial position, reputation and ability to win future business.
In addition, our products cannot be tested and proven in all situations and are otherwise subject to unforeseen problems that can negatively affect revenue, schedule and profitability, and result in loss of life or property. They include loss on launch or flight of spacecraft, loss of aviation platforms, premature failure of products that cannot be accessed for repair or replacement, unintended explosions, problems with design, quality and workmanship, country of origin of procured materials, inadequate supplier components and degradation of product performance. Factors that may affect revenue and profitability also include: inaccurate cost estimates, design issues, human factors, unforeseen costs and expenses, diversion of management focus, loss of follow-on work, replacement obligations, and repayment to the government customer of certain contract cost and fee payments previously received.
NORTHROP GRUMMAN CORPORATION
Certain contracts, primarily involving space satellite systems, contain provisions that entitle the customer to recover payments and/or fees in the event of failure of the system or other performance challenges upon launch or subsequent deployment for less than a specified period of time. Under such terms, we are generally required to forfeit fees previously recognized and/or collected.
•We provide products and services, including related to hazardous and high risk operations, which subjects us to various environmental, regulatory, financial, reputational and other risks, and if any of these risks were to materialize, it could have a material adverse effect on our reputation and our financial position, results of operations and/or cash flows .
We provide products and services related to hazardous and high risk operations. Among other such operations, our products and services are used in nuclear-related activities (including nuclear-powered platforms) and used in support of nuclear-related operations of third parties. In addition, certain of our products are provided with space and missile launches. We use and provide energetic materials, including in propulsion systems, which are highly explosive and flammable. We develop missile systems, and counter systems, including strategic deterrents, as well as subsystems and components. These and other activities subject us to various extraordinary risks, including those associated with (1) nuclear-related or non-nuclear launch activities and operations, including failed launches; (2) unintended release or initiation of energetic materials and explosions, whether in the development, test or use of such energetic materials; and (3) the storage, handling and disposal of radioactive and other hazardous or flammable materials and any changes in related regulations. We may be subject to potential liabilities, including for personal injury and harm to human health, property damage, environmental harm, and reputational harm arising out of such incidents or hazardous activities and operations, whether or not the cause was within our control, and insurance may not be reasonably available. Under some circumstances, the U.S. government and prime contractors may provide for certain indemnification and other protection, including pursuant to, or in connection with, Public Law 85-804, 10 U.S.C. 3861, the Price-Anderson Nuclear Industries Indemnity Act, the NASA Space Act, the Commercial Space Launch Act and the Terrorism Risk Insurance Reauthorization Act, for certain risks, but those protections may not be available or adequate.
Certain of our products, such as medium and large caliber ammunition and propulsion systems, involve the use, manufacture and/or handling of a variety of explosive and flammable materials or other hazardous substances. These activities have resulted and may result in incidents that cause workplace injuries and fatalities, the temporary shut down or other disruption of manufacturing, production delays, environmental harm and expense, fines and liabilities to third parties. We have safety and loss prevention programs, which provide for pre-construction reviews, along with safety audits of operations involving explosive materials, to attempt to avoid or mitigate some such incidents, as well as potentially insurance coverage and indemnification to address resulting liabilities, but they may not be successful.
In addition, our customers may use, handle or test our products and services in ways that can be unusually hazardous or risky, or in ways that are not intended, not authorized or inconsistent with guidance and warnings, which may create potential liabilities for our company, as well as reputational harm.
•We may not be able to adequately protect and fully exploit our intellectual property rights or obtain necessary rights to intellectual property of others, which could materially and adversely affect our ability to compete and perform on contracts, and have a material adverse effect on our reputation and our financial position, results of operations and/or cash flows.
To perform on our contracts and to win new business, we depend on our ability to develop, protect and exploit our intellectual property and use the intellectual property of others. Increasing demands from our customers to access and obtain rights in our intellectual property, and positions taken by our suppliers and competitors challenge our ability to protect and exploit intellectual property.
We own many forms of intellectual property, including trade secrets, U.S. and foreign patents, trademarks, and copyrights, and we license or otherwise obtain access to various intellectual property rights of third parties. The U.S. government and certain foreign governments hold licenses or other rights to certain intellectual property that we develop in performance of government contracts, and at times seek to use or authorize others to use such intellectual property, including in competition with us. Governments continue to increase efforts to obtain more extensive rights in contractors’ intellectual property, including where we do not believe they are entitled to do so under current law. This could reduce our ability to develop, protect and exploit certain of our intellectual property rights and to compete.
NORTHROP GRUMMAN CORPORATION
Our products and services embody valuable trade secrets, proprietary information and know-how. We typically seek to protect this information by entering into confidentiality and intellectual property agreements with our employees and third parties such as consultants, collaborators and suppliers. These agreements and other measures may not provide adequate protection for our trade secrets and other proprietary information. In the event of misuse, theft or misappropriation of such intellectual property rights or breach of confidentiality obligations, we may not have adequate legal remedies. In addition, our trade secrets or other proprietary information may otherwise become known or be independently developed by competitors.
In some instances, our ability to win or perform contracts requires us to use third party intellectual property. This may require the government or our customer to provide rights to such third party intellectual property or for us to negotiate directly with third parties to obtain necessary rights on reasonable terms,which may not be practicable.
Our intellectual property is subject to challenge, invalidation, or circumvention by third parties. Our access to and use of intellectual property licensed or otherwise obtained from third parties is also subject to challenges. Litigation to determine the scope of intellectual property rights, even if ultimately successful, has been and could in the future be costly. Moreover, the legal framework concerning intellectual property rights varies among countries and the protections under foreign laws and courts may not be favorable.
General and Other Risk Factors
•Our insurance coverage, customer indemnifications or other liability protections may be unavailable or inadequate to cover our significant risks, which could have a material adverse effect on our financial position, results of operations and/or cash flows.
We endeavor to obtain insurance from financially stable, responsible, highly rated counterparties in established markets to cover significant risks and liabilities (including, for example, natural disasters, space launches and on-orbit operations, cyber security, hazardous operations, energetics and products liability). Not every risk or liability can be insured, and insurance coverage is not always reasonably available. The policy limits and terms of coverage reasonably obtainable may not be sufficient to cover actual losses or liabilities. For example, the space insurance markets are experiencing increased price volatility and capacity constraint. Due to recent increases in the frequency and severity of losses, insurers are decreasing limits, increasing pricing and some have exited the market. Even if insurance coverage is available, we are not always able to obtain it at a price or on terms acceptable to us or without increasing exclusions. Disputes with insurance carriers over the availability of coverage, and the insolvency of one or more of our insurers has affected and may continue to affect the availability or timing of recovery, as well as our ability to obtain insurance coverage at reasonable rates in the future. In some circumstances we may be entitled to certain legal protections or indemnifications from our customers through contractual provisions, laws or otherwise. However, these protections are not always available, are difficult to negotiate and obtain, are typically subject to certain terms or limitations, including the availability of funds, and may not be sufficient to cover our losses or liabilities.
•Pension and other postretirement benefit (OPB) obligations and related expenses and funding requirements may fluctuate significantly depending upon investment performance of plan assets, changes in actuarial assumptions, and legislative or other regulatory actions.
The company’s pension and OPB obligations and related expenses are dependent upon the investment performance of plan assets and various assumptions, including discount and interest rates, mortality and the estimated long-term rates of return on plan assets. Changes in assumptions associated with our pension and OPB plans, investment performance of plan assets, and gains or losses associated with changes in valuation of marketable securities related to our non-qualified plans and other non-operating assets could have a material adverse effect on our financial position, results of operations and/or cash flows.
Funding requirements for our pension plans, including Pension Benefit Guaranty Corporation premiums, are subject to legislative and other government regulatory actions. In accordance with government regulations, pension plan cost recoveries under our U.S. government contracts may occur in different periods from when they are recognized for financial statement purposes or when pension funding is made. These timing differences, as well as government challenges to pension and OPB cost recovery, could have a material adverse effect on our financial position, results of operations and/or cash flows.
•Business investments and/or recorded goodwill and other long-lived assets may become impaired, which could have a material adverse effect on our financial condition and/or results of operations.
Goodwill is an intangible asset that we recognize in connection with acquisitions of third-party businesses. Goodwill accounts for approximately 35 percent of our total assets as of December 31, 2024. Other long-lived assets
NORTHROP GRUMMAN CORPORATION
principally comprise property, plant and equipment (PP&E) used in operating our business. The cost of PP&E utilized in support of our commercial business, including approximately $575 million of PP&E in our commercial space business, is not allocable to government contracts and is therefore subject to greater recoverability risk than PP&E utilized in support of our U.S. government contracts. Although the fair value of our reporting units and the net realizable value of our other long-lived assets currently exceed their respective carrying values, changes in business conditions, the market-based inputs used in our goodwill impairment test, or our assumptions related to the recoverability of our long-lived assets, could result in significant write-offs of goodwill or other long-lived assets.

ITEM 3. LEGAL PROCEEDINGS
Item 3. Legal Proceedings
We have provided information about certain legal proceedings in which we are involved in Notes 10 and 11 to the consolidated financial statements.
We are a party to various investigations, lawsuits, arbitration, claims, enforcement actions and other legal proceedings, including government investigations and claims, that arise in the ordinary course of our business. These types of matters could result in administrative, civil or criminal fines, penalties or other sanctions (which terms include judgments or convictions and consent or other voluntary decrees or agreements); compensatory, treble or other damages; non-monetary relief; or other liabilities. Government regulations provide that certain allegations against a contractor may lead to suspension or debarment from future government contracts or suspension of export privileges for the company or one or more of its components. The nature of legal proceedings is such that we cannot assure the outcome of any particular matter. For additional information on pending matters, please see Notes 10 and 11 to the consolidated financial statements, and for further information on the risks we face from existing and future investigations, lawsuits, arbitration, claims, enforcement actions and other legal proceedings, please see “Risk Factors.”
Consistent with SEC Regulation S-K Item 103, we have elected to disclose those environmental proceedings with a governmental entity as a party where the company reasonably believes such proceeding would result in monetary sanctions, exclusive of interest and costs, of $1.0 million or more.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS
Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations
OVERVIEW
The following discussion should be read along with the financial statements included in this Form 10-K, as well as Part II, “Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations” (MD&A) of our Form 10-K for the year ended December 31, 2023 (“2023 Annual Report on Form 10-K”). To the extent the July 1, 2024 SDS realignment impacted the disclosures in the 2023 Annual Report on Form 10-K, we recast those prior year MD&A disclosures herein.
Global Security Environment
The U.S. and its allies continue to face a global security environment of heightened tensions and instability, threats from state and non-state actors, including in particular major global powers, as well as terrorist organizations, increasing nuclear tensions, diverse regional security concerns and political instability. The market for defense products, services and solutions globally is driven by these complex and evolving security challenges, considered in the broader context of political and socioeconomic circumstances and priorities. Our operations and financial performance, as well as demand for our products and services, are impacted by these events, including global unrest. The same is true for our suppliers and other business partners.
The conflicts in Ukraine and the Middle East and threats elsewhere, particularly in the Pacific region, have increased global tensions and instability and highlighted security requirements globally, including in Europe, the Middle East and the Pacific region, as well as the U.S. These conflicts have resulted in and may continue to result in increased demand for defense products and services from allies and partner nations, particularly in those areas. For example, we have experienced an increase in demand for certain of our products and services directly and indirectly related to the conflict in Ukraine. We continue to monitor developments in these regions, but have not experienced, and do not anticipate experiencing, significant adverse financial impacts directly from the conflicts in Ukraine or the Middle East.
We believe the current global security environment highlights the significant national security threats to the U.S. and its allies, and the need for strong deterrence and robust defense capabilities, and are actively evaluating both opportunities and risks associated with this environment. We believe our capabilities, particularly in space, C4ISR, missile defense, battle management, advanced weapons, strategic deterrence, and survivable aircraft and mission systems should help our customers in the U.S. and globally defend against current and future threats and, as a result, continue to allow for long-term profitable business growth.
Global Economic Environment
Over the past several years, the global economic environment has experienced extraordinary challenges, including inflationary pressures; widespread delays and disruptions in supply chains; business slowdowns or shutdowns; workforce challenges and labor shortfalls; and market volatility. These macroeconomic factors have contributed, and in the future could contribute, to increased costs, delays, disruptions and other performance challenges, as well as increased competing demands for limited resources to address such increased costs and other challenges, for our company, our suppliers and partners, and our customers. We continue to work to address challenges caused by the macroeconomic environment on our business. We have seen positive progress in the supply chain as on-time deliveries and quality have improved. In remaining areas of pressure, we are proactively working with our suppliers to ensure we meet our contract commitments. Although certain pockets of our business were adversely affected by the broader macroeconomic environment during the fourth quarter of 2024, the overall financial impact on our company has continued to subside.
In addition, an overall increase in interest rates in recent years has raised the cost of borrowing for governments, and if rates further increase, it could impact government spending priorities (in the U.S. and allied countries, in particular), including their demand for defense products. Economic tensions and changes in international trade policies, including higher tariffs on imported goods and materials, the imposition of retaliatory tariffs or other trade protection measures and renegotiation of free trade agreements, could also further impact the global market for defense products, services and solutions.
U.S. Political, Budget and Regulatory Environment
The U.S. continues to face an uncertain and evolving political, budget and regulatory environment. In particular, it is difficult to predict the specific course of future defense budgets. Current and future requirements related to the conflicts in Ukraine and the Middle East, threats in the Pacific region and other security priorities, as well as the macroeconomic environment, the national debt, and other domestic priorities, among other things, in the U.S. and globally, will continue to impact our customers’ budgets, spending and priorities, and our industry. The U.S. political environment may also impact defense budgets and priorities, issues related to the national debt, and
NORTHROP GRUMMAN CORPORATION
government spending more broadly. We anticipate that issues related to budgetary priorities and defense spending levels, the debt ceiling, and the spending caps imposed by the Fiscal Responsibility Act of 2023 (FRA), particularly with respect to discretionary spending, will continue to be a subject of considerable debate, with a potentially significant impact on our programs and the company.
Annual appropriations to fund the federal government for FY 2025 have not yet been enacted. Congress continues to pass short-term continuing resolutions (CR) to fund the federal government. The most recent CR passed in December 2024 extends current funding levels until March 14, 2025. It remains uncertain when the government will approve FY 2025 appropriations, and the levels of funding FY 2025 appropriations will provide. Government operations under an extended CR could have potential impacts on our programs and new starts, in particular.
The political environment, federal budget, debt ceiling and regulatory environment, including potential tax reform, are expected to continue to be the subject of considerable debate, especially in light of the ongoing conflicts and heightened global tensions, the macroeconomic environment and political tensions. The results of those debates could have material impacts on defense spending broadly and the company’s programs in particular.
B-21 Program
In 2015, the U.S. Air Force awarded Northrop Grumman the B-21 contract, which includes a base contract for engineering and manufacturing development (EMD) and five low-rate initial production (LRIP) options for a baseline total of 21 aircraft. The EMD phase of the program is largely cost type and began at contract award. The LRIP options are largely fixed price and are expected to continue to be awarded and executed through approximately the end of the decade. In addition to the five LRIP options, Northrop Grumman and the U.S. Air Force have established not to exceed (NTE) pricing for additional aircraft up to unit 40. The average NTE value for these subsequent lots is above the average unit price of the five LRIP lots, and the NTE lots include an economic price adjustment clause to help protect against certain inflationary pressures. Final terms, quantity, and pricing for these subsequent lots are not fully negotiated.
During the fourth quarter of 2023, we recognized a projected loss of $1.56 billion across the five LRIP options. During the fourth quarter of 2024, we again reviewed our estimated profitability on the program and made no significant changes to the previously recognized loss. The company’s 2024 results reflect our current best estimate of our cost to complete the LRIP and NTE aircraft, as well as the outcome of ongoing discussions with our suppliers and our customer. If our estimated cost to complete the aircraft changes or our assumptions regarding contract performance, quantities, supplier negotiations, or funding to mitigate the impact of macroeconomic disruptions are resolved more or less favorably than what we have estimated, our financial position, results of operations and/or cash flows could be materially affected.
Sentinel Program
In 2020, the U.S. Air Force awarded Northrop Grumman a $13.3 billion contract for the EMD phase of the Sentinel program. In January 2024, the U.S. Air Force provided congressional notification that the Sentinel program was under a Nunn-McCurdy breach review, which is required when total program cost estimates exceed certain defined thresholds. This notification, which had been driven primarily by increases in cost estimates for the Production and Deployment phases, commenced the process to achieve certification for continuance of the program and update its baseline cost estimates. We are currently executing under a cost-type contract for the EMD phase, and the Production and Deployment phases are yet to be priced and negotiated.
In July 2024, the Sentinel program was certified for continuation by the DoD upon completion of the Nunn-McCurdy breach review. In connection with the certification, the DoD directed that the program be restructured, including plans for infrastructure related to the command and launch segment, which was the main driver of the increased cost estimates for the Production and Deployment phases. We are partnering with our customer to establish a new program baseline as part of the restructuring activities.
During the fourth quarter of 2024, we reviewed our estimated profitability on the Sentinel program and made no significant changes. The Sentinel EAC incorporates our best estimate of costs to complete the restructured EMD effort; however, if the outcome is more or less favorable than what we have estimated, our financial position, results of operations and/or cash flows could be materially affected.
Operating Performance Assessment and Reporting
We manage and assess our business based on our performance on contracts and programs (typically larger contracts or two or more closely-related contracts). We recognize sales from our portfolio of long-term contracts as control is transferred to the customer, primarily over time on a cost-to-cost basis (cost incurred relative to costs estimated at completion). As a result, sales tend to fluctuate in concert with costs incurred across our large portfolio of contracts.
NORTHROP GRUMMAN CORPORATION
Due to the applicable FAR and CAS requirements that govern our U.S. government business, most types of costs are allocable to U.S. government contracts. As such, we do not focus on individual cost groupings (such as manufacturing, engineering and design labor, subcontractor, material, overhead and general and administrative (G&A) costs), as much as we do on total contract cost, which is the key driver of our sales and operating income.
In evaluating our operating performance, we primarily focus on changes in sales and operating margin rates. Where applicable, significant fluctuations in operating performance attributable to individual contracts or programs, or changes in a specific cost element across multiple contracts, are described in our analysis. Based on this approach and the nature of our operations, the discussion of results of operations below first focuses on our four segments before distinguishing between products and services. Changes in sales are generally described in terms of volume, while changes in operating margin rates are generally described in terms of performance and/or contract mix. For purposes of this discussion, volume generally refers to increases or decreases in sales or cost from production/service activity levels and performance generally refers to non-volume-related changes in profitability, which are typically described in terms of changes in net EAC adjustments. Contract mix generally refers to changes in the ratio of contract type and/or life cycle (e.g., cost-type, fixed-price, development, production, and/or sustainment).

For purposes of the operating results discussion below, we assess our performance using certain financial measures that are not calculated in accordance with accounting principles generally accepted in the United States of America (“GAAP” or “FAS”).
Mark-to-market adjusted net earnings (MTM-adjusted net earnings) and MTM-adjusted earnings per share (MTM-adjusted EPS) exclude MTM pension and OPB benefit/(expense) and related tax impacts, which are generally only recognized during the fourth quarter. These non-GAAP measures may be useful to investors and other users of our financial statements as supplemental measures in evaluating the company’s underlying financial performance by presenting the company’s operating results before the non-operational impact of pension and OPB actuarial gains and losses. These measures are also consistent with how management views the underlying performance of the business as the impact of MTM accounting is not considered in management’s assessment of the company’s operating performance or in its determination of incentive compensation awards.
We reconcile these non-GAAP financial measures to their most directly comparable GAAP financial measures below. These non-GAAP measures may not be defined and calculated by other companies in the same manner and should not be considered in isolation or as an alternative to operating results presented in accordance with GAAP.
Selected financial highlights are presented in the table below:

Sales
2024 sales increased $1.7 billion, or 4 percent, due to a 12 percent growth in sales at Aeronautics Systems and higher sales at Mission Systems and Defense Systems, partially offset by lower sales at Space Systems largely driven by a reduction of $595 million associated with wind-down of work on the restricted space and NGI programs, as previously disclosed. 2024 sales reflect continued strong demand for our products and services.

See “Segment Operating Results” below for further information by segment and “Product and Service Analysis” for product and service detail. See Note 15 to the consolidated financial statements for information regarding the company’s sales by customer type, contract type and geographic region for each of our segments.
Operating Income and Margin Rate
2024 operating income increased $1.8 billion, or 72 percent, primarily due to higher operating income at Aeronautics Systems, largely driven by the prior year $1.56 billion charge on the B-21 program, as well as higher operating income at Space Systems and Defense Systems. 2024 operating income also increased due to a $122 million increase in the FAS/CAS operating adjustment, partially offset by $73 million of higher unallocated corporate expense, largely due to a $127 million increase in deferred state taxes related to the MTM benefit (expense) and prior year B-21 charge and $25 million of lower intangible amortization and PP&E step-up depreciation. 2024 operating margin rate increased to 10.6 percent from 6.5 percent reflecting the items above.
2024 G&A costs as a percentage of sales decreased to 9.7 percent from 10.2 percent primarily due to higher sales.
For further information regarding product and service operating costs and expenses, see “Product and Service Analysis” below.
Mark-to-Market Pension and OPB Benefit/Expense
The primary components of pre-tax MTM benefit (expense) are presented in the table below:
Year Ended December 31
$ in millions 2024 2023 2022
Actuarial gains (losses) on projected benefit obligation $ 1,314 $ (1,489) $ 9,662
Actuarial (losses) gains on plan assets (871) 1,067 (8,430)
MTM benefit (expense)
$ 443 $ (422) $ 1,232
The 2024 MTM benefit of $443 million was primarily driven by a 58 basis point increase in the discount rate from year end 2023, partially offset by actual net plan asset returns of 4.7 percent compared to our 7.5 percent asset return assumption.
Federal and Foreign Income Taxes
The 2024 effective tax rate (ETR) increased to 16.8 percent from 12.4 percent in 2023 primarily due to the impact of the prior year B-21 charge and the MTM adjustment on our ETR. The 2024 MTM benefit increased the 2024 ETR by 0.4 percentage points, whereas the prior year B-21 charge and MTM expense collectively reduced the 2023 ETR by 3.8 percentage points. The 2024 ETR also reflects a net reduction in tax reserves largely due to a recent federal court decision, partially offset by higher interest expense on unrecognized tax benefits. See Note 6 to the consolidated financial statements for additional information.

(2)The federal tax impact in each period was calculated by subtracting the deferred state tax impact from MTM benefit (expense) and applying the 21 percent federal statutory rate.
2024 net earnings increased $2.1 billion, or 103 percent, primarily due to $1.8 billion of higher operating income, an $865 million increase in our MTM benefit (expense), and a $126 million increase in the non-operating FAS pension benefit. These increases were partially offset by a $552 million increase in income tax expense, a $97 million gain

SEGMENT OPERATING RESULTS
Basis of Presentation
The company is aligned in four operating sectors, which also comprise our reportable segments: Aeronautics Systems, Defense Systems, Mission Systems and Space Systems.
Effective July 1, 2024, the company realigned the Strategic Deterrent Systems (SDS) division, which includes the Ground-Based Strategic Deterrent (“Sentinel”) program, from Space Systems to Defense Systems. This realignment is reflected in the financial information contained in this report.
Subsequent Realignment - Effective January 1, 2025, the company realigned the Strike and Surveillance Aircraft Solutions (SSAS) business unit from Defense Systems to Aeronautics Systems. This realignment is not reflected in the financial information contained in this report; it will be reflected in the company’s operating results beginning in the first quarter of 2025.
For a more complete description of each segment’s products and services, see “Business.”
Segment Operating Income and Margin Rate
Segment operating income, as reconciled in the table below, and segment operating margin rate (segment operating income divided by sales) are non-GAAP measures that reflect the combined operating income of our four segments less the operating income associated with intersegment sales. Segment operating income includes pension expense allocated to our sectors under FAR and CAS and excludes FAS pension service expense and unallocated corporate items (certain corporate-level expenses, which are not considered allowable or allocable under applicable FAR and CAS requirements, and costs not considered part of management’s evaluation of segment operating performance). These non-GAAP measures may be useful to investors and other users of our financial statements as supplemental measures in evaluating the financial performance and operational trends of our sectors. These measures may not be defined and calculated by other companies in the same manner and should not be considered in isolation or as alternatives to operating results presented in accordance with GAAP.

Segment Operating Income and Margin Rate
2024 segment operating income increased $1.8 billion, or 65 percent, primarily due to higher operating income at Aeronautics Systems, largely driven by the prior year $1.56 billion charge on the B-21 program, as well as higher operating income at Space Systems and Defense Systems. Segment operating margin rate increased to 11.1 percent reflecting higher operating margin rates at Aeronautics Systems and Space Systems, partially offset by a lower operating margin rate at Mission Systems.
FAS/CAS Operating Adjustment
The 2024 FAS/CAS operating adjustment reflects higher CAS pension expense largely driven by plan asset returns in prior years and changes in certain CAS actuarial assumptions as of December 31, 2023.
Unallocated Corporate Expense
The increase in 2024 unallocated corporate expense is primarily due to a $127 million increase in deferred state taxes associated with the prior year B-21 charge and the MTM adjustment, partially offset by lower intangible asset amortization and PP&E step-up depreciation and a loss recognized in the prior year in connection with the divestiture of a small international subsidiary.
Net Estimate-At-Completion (EAC) Adjustments - We record changes in estimated contract earnings at completion (net EAC adjustments) using the cumulative catch-up method of accounting.

NORTHROP GRUMMAN CORPORATION
Sales
2024 sales increased $271 million, or 3 percent, primarily due to a $182 million increase on Sentinel as that program continues to ramp, a $163 million increase on certain military ammunition programs, a $124 million increase on Stand-in Attack Weapon (SiAW) as the program ramps and higher volume from timing of materials and increased order quantities on the Guided Multiple Launch Rocket System (GMLRS) program. These increases were partially offset by a $262 million decrease due to the completion of an international training program and lower volume on the Special Electronic Mission Aircraft (SEMA) program as it nears completion.
2023 sales increased $660 million, or 9 percent, primarily due to a $426 million increase driven by Sentinel ramp-up, as well as higher volume on ammunition programs, GMLRS, an international training program, Hypersonic Attack Cruise Missile (HACM), and SiAW.
Operating Income
2024 operating income increased $37 million, or 4 percent, primarily due to higher sales. Operating margin rate was comparable to the prior period.
2023 operating income increased $48 million, or 6 percent, due to higher sales, partially offset by a lower operating margin rate. Operating margin rate decreased to 10.0 percent from 10.2 percent, primarily due to lower net EAC adjustments.

Sales
2024 sales increased $504 million, or 5 percent, primarily due to higher volume on restricted advanced microelectronics and technology programs, increased marine systems sales due, in part, to the timing of materials, and higher Ground/Air Task Oriented Radar (G/ATOR) volume due to continued ramp-up on full-rate production (FRP) awards. These increases were partially offset by lower sales on restricted airborne radar programs and the Scalable Agile Beam Radar (SABR) program.
Operating Income
2024 operating income decreased $11 million, or 1 percent, due to a lower operating margin rate, partially offset by higher sales. Operating margin rate decreased to 14.0 percent from 14.8 percent primarily due to lower net EAC adjustments on certain airborne radar production programs due, in part, to production inefficiencies that have driven higher labor costs, as well as changes in contract mix toward more cost-type content. These decreases were partially offset by sales growth on higher margin advanced microelectronics programs.

Sales
2024 sales decreased $142 million, or 1 percent, primarily due to wind-down of work on the restricted space and NGI programs, which reduced sales by $595 million. This reduction was partially offset by a $302 million increase on Space Development Agency (SDA) satellite programs and a $130 million increase on the Habitation and Logistics Outpost (HALO) program.
2023 sales increased $1.3 billion, or 12 percent, primarily due to higher volume on restricted programs and ramp-up on development programs, including $333 million on the Next-Gen Polar program, $219 million on the NGI program, $119 million on the SDA Tranche 1 Tracking Layer program and $102 million on the SDA Tranche 2 Transport Layer program. These increases were partially offset by a $172 million decrease for CRS missions and a $109 million decrease on the HALO program.
Operating Income
2024 operating income increased $124 million, or 11 percent, primarily due to a higher operating margin rate. Operating margin rate increased to 10.7 percent from 9.5 percent primarily due to higher net EAC adjustments largely driven by the HALO program as previously disclosed.
2023 operating income increased $52 million, or 5 percent, due to higher sales, partially offset by a lower operating margin rate. Operating margin rate decreased to 9.5 percent from 10.2 percent primarily due to a prior year $96 million gain recognized in connection with a land exchange transaction, as well as lower net EAC adjustments driven by $100 million of unfavorable EAC adjustments on the HALO program in 2023. These decreases were partially offset by a $42 million benefit from insurance recoveries in our commercial space business during 2023.

Product Sales and Costs
2024 product sales increased $1.8 billion, or 6 percent, due to an increase in product sales at all four sectors. The increase was principally driven by higher volume on restricted programs,, Triton and E-2 at Aeronautics Systems, higher volume on Sentinel, certain military ammunition programs, SiAW and GMLRS at Defense Systems, higher restricted sales, partially offset by lower SABR volume, at Mission Systems and sales growth on SDA satellite programs and HALO, partially offset by wind-down of work on the restricted space and NGI programs, at Space Systems.
2023 product sales increased $2.4 billion, or 8 percent, due to an increase in product sales at all four sectors. The increase was principally driven by higher volume on restricted programs and NGI at Space Systems, higher volume on Sentinel, ammunition programs, GMLRS, HACM, and the Integrated Battle Command System (IBCS) program at Defense Systems, and higher restricted sales at Mission Systems and Aeronautics Systems.
2024 product costs were comparable to the prior year, reflecting a higher operating margin rate principally due to the prior year $1.56 billion charge on the B-21 program at Aeronautics Systems and higher EAC adjustments at Space Systems, largely driven by the HALO program.
2023 product costs increased $4.0 billion, or 16 percent, consistent with the higher product sales described above and reflect a lower operating margin rate principally due to the previously described $1.56 billion charge on the B-21 program at Aeronautics Systems and lower net EAC adjustments on Space Systems production programs.
NORTHROP GRUMMAN CORPORATION
Service Sales and Costs
2024 service sales decreased $86 million, or 1 percent, primarily due to a decrease in service sales at Defense Systems principally due to the completion of an international training program and lower volume on SEMA, partially offset by an increase in service sales at Aeronautics Systems driven by higher volume on restricted programs and Global Hawk.
2023 service sales increased $313 million, or 4 percent, due to an increase in service sales at Space Systems, Mission Systems, and Aeronautics Systems. The increase was principally driven by higher restricted sales at Space Systems and Aeronautics Systems, and higher volume on restricted programs and sustainment at Mission Systems.
2024 service costs were comparable to the prior year, consistent with the change in services sales described above.
2023 service costs increased $186 million, or 3 percent, consistent with the higher service sales described above and reflects a higher operating margin rate on Space Systems service programs.
BACKLOG
Backlog represents the future sales we expect to recognize on firm orders received by the company and is equivalent to the company’s remaining performance obligations at the end of each period. It comprises both funded backlog (firm orders for which funding is authorized and appropriated) and unfunded backlog. Unexercised contract options and indefinite delivery indefinite quantity (IDIQ) contracts are not included in backlog until the time the option or IDIQ task order is exercised or awarded. Backlog is converted into sales as costs are incurred or deliveries are made.
Backlog consisted of the following at December 31, 2024 and 2023:
2024 2023

Total backlog $ 39,662 $ 51,806 $ 91,468 $ 84,230 9 %
2024 net awards totaled $50.6 billion. Significant 2024 new awards include $11.8 billion for restricted programs (primarily at Aeronautics Systems, Mission Systems, and Space Systems), $3.5 billion for the Take Charge and Move Out (TACAMO) mission, $3.5 billion for (primarily at Aeronautics Systems), $2.4 billion for E-2, $1.8 billion for Next-Gen OPIR Polar, $0.9 billion for Poland IBCS, and $0.8 billion for certain military ammunition programs.
During 2024, the company reduced unfunded backlog by $1.6 billion and $0.7 billion related to terminations for convenience in our restricted space business and on the NGI program at Space Systems, respectively.
LIQUIDITY AND CAPITAL RESOURCES
We are focused on the efficient conversion of operating income into cash to provide for the company’s material cash requirements, including working capital needs, satisfaction of contractual commitments, funding of our pension and OPB plans, investment in our business through capital expenditures, and shareholder return through dividend payments and share repurchases.
As of December 31, 2024, we had cash and cash equivalents of $4.4 billion; $268 million was held outside of the U.S. by foreign subsidiaries. We expect cash and cash equivalents and cash generated from operating activities, supplemented by borrowings under credit facilities, commercial paper and/or in the capital markets through our shelf registration with the SEC, if needed, to be sufficient to provide liquidity to the company in the short-term and long-term. The company has a five-year senior unsecured credit facility in an aggregate principal amount of $2.5 billion, and in April 2024, we renewed our one-year $500 million uncommitted credit facility. At December 31, 2024, there were no borrowings outstanding under these credit facilities. In January 2024, we issued $2.5 billion of unsecured senior notes for general corporate purposes, including debt repayment, share repurchases and working capital.
The company’s principal contractual commitments include purchase obligations, repayments of long-term debt and related interest, and payments under operating leases. At December 31, 2024, we had $20.5 billion of purchase obligations, approximately half of which is short-term. Purchase obligations are largely comprised of open purchase
NORTHROP GRUMMAN CORPORATION
order commitments to suppliers and subcontractors under U.S. government contracts. In most circumstances, our risk associated with the purchase obligations on our U.S. government contracts is limited to the termination liability provisions within those contracts. As such, we do not believe they represent a material liquidity risk to the company. At December 31, 2024, we had capital expenditure commitments of $1.5 billion, which we expect to satisfy with cash on hand. We also had provisions for uncertain tax positions of $1.4 billion, some or all of which could result in future cash payments to various taxing authorities. At this time, we are unable to estimate the timing and amount of any future cash outflows related to these uncertain tax positions.
Refer to the respective notes to the consolidated financial statements for further information about our share repurchase programs (Note 2), commercial paper, credit facilities and long-term debt (Note 9), standby letters of credit and guarantees (Note 11), future minimum contributions for the company’s pension and OPB plans (Note 12), and lease payment obligations (Note 14).
Income Tax Matters
During the fourth quarter of 2024, the company entered into an agreed Revenue Agent’s Report (“RAR”) for certain matters related to the company’s 2018-2020 federal income tax returns, largely related to our methods of accounting associated with the timing of revenue recognition and related costs under IRC Section 451(b). The company made a $956 million payment in December 2024, inclusive of associated interest, in connection with the agreed RAR. Refer to Note 6 to the financial statements for further information about our unrecognized tax benefits.
Beginning in 2022, the Tax Cuts and Jobs Act of 2017 (“TCJA”) eliminated the option to deduct research and development expenditures in the current year and requires taxpayers to amortize them over five years pursuant to IRC Section 174. Our 2024 and 2023 cash from operations were reduced for federal estimated tax payments we made related to Section 174 of approximately $350 million and $500 million, respectively. In the future, Congress may consider legislation that would defer the amortization requirement to later years, possibly with retroactive effect. In the meantime, we expect to continue to make additional federal tax payments based on the current Section 174 tax law, which we estimate will reduce our 2025 cash from operations by approximately $230 million. The impact of Section 174 on our cash from operations depends on the amount of research and development expenditures incurred by the company and whether the IRS issues guidance on the provision which differs from our current interpretation, among other things.
Cash Flow Measures
In addition to our cash position, we consider various cash flow measures in capital deployment decision-making, including cash provided by operating activities and adjusted free cash flow, a non-GAAP measure described in more detail below.
Operating Cash Flow
The table below summarizes key components of cash provided by operating activities:
Year Ended December 31
$ in millions 2024 2023 2022
Net earnings $ 4,174 $ 2,056 $ 4,896
B-21 charge - 1,559 -
Non-cash items(1)
8 551 (1,305)
Pension and OPB contributions (129) (139) (136)
Changes in trade working capital 274 (144) (600)
Other, net 61 (8) 46
Net cash provided by operating activities $ 4,388 $ 3,875 $ 2,901
(1)Includes depreciation and amortization, non-cash lease expense, MTM benefit (expense), stock based compensation expense, deferred income taxes and net periodic pension and OPB income.
2024 cash provided by operating activities increased $513 million, or 13 percent, principally due to improved trade working capital, largely driven by lower net tax payments, as well as higher net earnings.
Adjusted Free Cash Flow
Adjusted free cash flow, as reconciled in the table below, is a non-GAAP measure defined as net cash provided by or used in operating activities, less capital expenditures, plus proceeds from the sale of equipment to a customer (not otherwise included in net cash provided by or used in operating activities) and the after-tax impact of discretionary pension contributions, if any. Adjusted free cash flow includes proceeds from the sale of equipment to a customer as
NORTHROP GRUMMAN CORPORATION
such proceeds were generated in a customer sales transaction. It also includes the after-tax impact of discretionary pension contributions for consistency and comparability of financial performance. This measure may not be defined and calculated by other companies in the same manner. We use adjusted free cash flow as a key factor in our planning for, and consideration of, acquisitions, the payment of dividends and stock repurchases. This non-GAAP measure may be useful to investors and other users of our financial statements as a supplemental measure of our cash performance, but should not be considered in isolation, as a measure of residual cash flow available for discretionary purposes, or as an alternative to operating cash flows presented in accordance with GAAP.
The table below reconciles net cash provided by operating activities to adjusted free cash flow:
Year Ended December 31 % Change in
$ in millions 2024 2023 2022 2024 2023
Net cash provided by operating activities $ 4,388 $ 3,875 $ 2,901 13 % 34 %
Capital expenditures (1,767) (1,775) (1,435) - % 24 %
Proceeds from sale of equipment to a customer - - 155 NM (100) %
Adjusted free cash flow $ 2,621 $ 2,100 $ 1,621 25 % 30 %
2024 adjusted free cash flow increased $521 million, or 25 percent, principally due to higher net cash provided by operating activities.
Investing Cash Flow
2024 net cash used in investing activities increased $167 million principally due to the receipt of proceeds from the sale of minority investments in the prior year.
Financing Cash Flow
2024 net cash used in financing activities decreased $366 million primarily due to $1.05 billion of lower debt repayments and a $500 million increase in proceeds from long-term debt, partially offset by a $1.0 billion increase in share repurchases and a $70 million increase in dividends paid. Cash returned to shareholders through share repurchases and dividends totaled $3.7 billion in 2024 and $2.6 billion in 2023.
CRITICAL ACCOUNTING POLICIES AND ESTIMATES
Our consolidated financial statements are prepared in conformity with GAAP, which requires us to make estimates and assumptions about future events that affect the amounts reported in our consolidated financial statements. We employ judgment in making our estimates in consideration of historical experience, currently available information and various other assumptions that we believe to be reasonable under the circumstances. Actual results could differ from our estimates and assumptions, and any such differences could be material to our consolidated financial statements. We believe the following accounting policies are critical to the understanding of our consolidated financial statements and require the use of significant management judgment in their application. For a summary of our significant accounting policies, see Note 1 to the consolidated financial statements.
Revenue Recognition
Due to the long-term nature of our contracts, we generally recognize revenue over time using the cost-to-cost method, which requires us to make reasonably dependable estimates regarding the revenue and cost associated with the design, manufacture and delivery of our products and services.
Contract sales may include estimates of variable consideration, including cost or performance incentives (such as award and incentive fees), un-priced change orders, REAs and contract claims. Variable consideration is included in total estimated sales to the extent it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. We estimate variable consideration as the most likely amount to which we expect to be entitled.
Our cost estimation process is based on the professional knowledge of our engineering, program management and financial professionals, and draws on their significant experience and judgment. We prepare EACs for our contracts and calculate an estimated contract profit based on total estimated contract sales and cost. Since our contracts often span a period of several years, estimation of revenue, cost, and progress toward completion requires the use of judgment. Factors considered in these estimates include our historical performance, the availability, productivity and cost of labor, the nature and complexity of work to be performed, the effect of change orders, availability and cost of materials, components and subcontracts, the effect of any delays in performance and the level of indirect cost allocations.
NORTHROP GRUMMAN CORPORATION
We also consider the impact of macroeconomic factors on our estimates, in particular on contract EACs that span several years. For example, we have included in our EACs management’s best estimate of the impact inflation and disruptions in the supply chain have had and may continue to have on our contracts. Although the overall financial impact these macroeconomic factors have had on our company has largely subsided, volatility of the recent macroeconomic environment has added complexity to our estimation process and may result in our contract EACs having more variability in the future than they might otherwise have had if the estimates had been prepared in a more stable macroeconomic environment.
We generally review and reassess our sales, cost and profit estimates for each significant contract at least annually or more frequently as determined by the occurrence of events, changes in circumstances and evaluations of contract performance to reflect the latest reliable information available. These assessments require judgments and estimates that can be affected by any number of these factors over time, which may cause actual results to differ materially from those estimates as facts and circumstances change or become known to us.
The company performs on a broad portfolio of long-term contracts, including the development of complex and customized military platforms and systems, as well as advanced electronic equipment and software, that often include technology at the forefront of science. Cost estimates on fixed-price development contracts and early-stage/low-rate production contracts are inherently more uncertain as to future events than on mature, full-rate production contracts. As a result, there is typically more variability in those estimates and greater financial risk associated with unanticipated cost growth on fixed-price development contracts and early-stage/low-rate production contracts. Changes in estimates occur for a variety of reasons, including changes in contract scope, the resolution of risk at lower or higher cost than anticipated, unanticipated performance and other risks affecting contract costs, performance issues with subcontractors or suppliers, changes in indirect cost allocations, such as overhead and G&A costs, and changes in estimated award and incentive fees. Identified risks typically include technical, schedule and/or performance risk based on our evaluation of the contract effort. Similarly, the changes in estimates may include changes in, or resolution of, identified opportunities for operating margin improvement.
For the impacts of changes in estimates on our consolidated statements of earnings and comprehensive income, see “Segment Operating Results” and Note 1 to the consolidated financial statements.
Retirement Benefits
Overview - The determination of projected benefit obligations, the fair value of plan assets, and pension and OPB expense for our retirement benefit plans requires the use of estimates and actuarial assumptions. We perform an annual review of our actuarial assumptions in consultation with our actuaries. When we determine changes in the assumptions are warranted, or as a result of plan amendments, future pension and OPB expense and our projected benefit obligation could increase or decrease materially. The principal estimates and assumptions that have a significant effect on our consolidated financial position and results of operations are the discount rate, cash balance crediting rate, expected long-term rate of return on plan assets, estimated fair market value of plan assets, and the mortality rate of those covered by our pension and OPB plans. The effects of actual results differing from our assumptions and the effects of changing assumptions (i.e., actuarial gains or losses) are recognized immediately through earnings upon annual remeasurement in the fourth quarter, or on an interim basis as triggering events warrant remeasurement.
Discount Rate - The discount rate represents the interest rate used to determine the present value of future cash flows currently expected to be required to settle our pension and OPB obligations. The discount rate is generally based on the yield of high-quality corporate fixed-income investments. At the end of each year, we determine the discount rate using a theoretical bond portfolio model of bonds rated AA or better to match the notional cash outflows related to projected benefit payments for each of our significant benefit plans. Taking into consideration the factors noted above, our weighted-average composite pension discount rate was 5.73 percent at December 31, 2024 and 5.15 percent at December 31, 2023.
NORTHROP GRUMMAN CORPORATION
The effects of a hypothetical change in the discount rate may be nonlinear and asymmetrical for future years as the discount rate changes. Holding all other assumptions constant, an increase or decrease of 25 basis points in the December 31, 2024 discount rate assumption would have the following estimated effects on 2024 pension and OPB obligations, which would be reflected in the 2024 MTM expense (benefit), and 2025 expected pension and OPB expense:
$ in millions 25 Basis Point Decrease in Rate 25 Basis Point Increase in Rate
2024 pension and OPB obligation and MTM expense (benefit)
$ 785 $ (750)
2025 pension and OPB (benefit) expense
(20) 19
Cash Balance Crediting Rate - A portion of the company’s pension obligation and resulting pension expense is based on a cash balance formula, where participants’ hypothetical account balances are accumulated over time with pay-based credits and interest. Interest is credited monthly using the current 30-Year Treasury bond rate. The interest crediting rate is part of the cash balance formula and independent of actual pension investment returns. The cash balance crediting rate tends to move in concert with the discount rate but has an offsetting effect on pension benefit obligations and the related MTM expense (benefit). The minimum cash balance crediting rate allowed under the plan is 2.25 percent. The cash balance crediting rate assumption has been set to its current level of 4.78 percent as of December 31, 2024, increasing to 4.90 percent by 2030. Holding all other assumptions constant, an increase or decrease of 25 basis points in the December 31, 2024 cash balance crediting rate assumption would have the following estimated effects on the 2024 pension benefit obligation, which would be reflected in the 2024 MTM (benefit) expense, and 2025 expected pension expense:
$ in millions 25 Basis Point Decrease in Rate 25 Basis Point Increase in Rate
2024 pension obligation and MTM (benefit) expense
$ (101) $ 104
2025 pension (benefit) expense
(9) 9
Expected Long-Term Rate of Return on Plan Assets - The expected long-term rate of return on plan assets (EROA) assumption reflects the average rate of net earnings we expect on current and future benefit plan investments. EROA is a long-term assumption, which we review annually and adjust to reflect changes in our long-term view of expected market returns and/or significant changes in our plan asset investment policy. Due to the inherent uncertainty of this assumption, we consider multiple data points at the measurement date including the plan’s target asset allocation, historical plan asset returns and third-party projection models of expected long-term returns for each of the plans’ strategic asset classes. In addition to the data points themselves, we consider trends in the data points, including changes from the prior measurement date. The EROA assumptions we use for pension benefits are consistent with those used for OPB plans; however, we reduce the EROA for OPB plans to allow for the impact of tax on investment earnings, as certain Voluntary Employee Beneficiary Association trusts are taxable.
During 2024, the Investment Committee of the company’s benefit plans reviewed the plans’ major asset class allocations and approved an update to increase the target fixed-income asset allocation from 43% to 45%. The actual asset allocation as of December 31, 2024 was approximately 41% fixed-income, 29% public equities, 23% alternatives, 6% private credit and 1% cash. At this time, the Investment Committee is not planning any significant changes to that mix. For further information on plan asset investments, see Note 12 to the consolidated financial statements.
While historical market returns are not necessarily predictive of future market returns, given our long history of plan performance supported by the stability in our investment mix, investment managers, and active asset management, we believe our actual historical performance is a reasonable metric to consider when developing our EROA. Our average annual rate of return from 1976 to 2024 was approximately 10.5 percent and our 20-year and 30-year rolling average rates of return were approximately 7.5 percent and 8.9 percent, respectively, each determined on an arithmetic basis and net of expenses. Our 2024 return on plan assets, net of expenses, was approximately 4.7 percent.
Consistent with our past practice, we obtained long-term capital market forecasting models from several third parties and, using our target asset allocation, developed an expected rate of return on plan assets from each model. We
NORTHROP GRUMMAN CORPORATION
considered not only the specific returns projected by those third-party models, but also changes in the models year-to-year when developing our EROA.
For determining 2024 FAS expense, we assumed an expected long-term rate of return on pension plan assets of 7.5 percent and an expected long-term rate of return on OPB plan assets of 7.12 percent. For 2025 FAS expense, we have assumed an expected long-term rate of return on pension plan assets of 7.5 percent and 7.08 percent on OPB plans. Holding all other assumptions constant, an increase or decrease of 25 basis points in our December 31, 2024 EROA assumption would have the following estimated effects on 2025 expected pension and OPB expense:
$ in millions 25 Basis Point Decrease 25 Basis Point Increase
2025 pension and OPB expense (benefit)
$ 75 $ (75)
In addition, holding all other assumptions constant, an increase or decrease of 100 basis points in actual versus expected return on plan assets would have the following estimated effects on our 2025 MTM expense (benefit):
$ in millions 100 Basis Point Decrease 100 Basis Point Increase
2025 MTM expense (benefit)
$ 300 $ (300)
Estimated Fair Market Value of Plan Assets - For certain plan assets where the fair market value is not readily determinable, such as real estate, private equity, hedge funds and opportunistic investments, we develop estimates of fair value using the best information available. Estimated fair values on these plan assets are based on redemption values and net asset values (NAV), as well as valuation methodologies that include third-party appraisals, comparable transactions, discounted cash flow valuation models and public market data.
Mortality Rate - We use mortality assumptions to estimate life expectancies of plan participants. In October 2014, the Society of Actuaries Retirement Plans Experience Committee (RPEC) issued updated mortality tables and a mortality improvement scale, which reflected longer life expectancies than previously projected. In October 2019, the RPEC issued an updated mortality base table (the Private Retirement Plans Mortality table for 2012 (Pri-2012)), which we adopted after reviewing our own historical mortality experience. In October 2021, the RPEC released a new projection scale (MP-2021) that included additional underlying data for 2019, which included an increase in life expectancies relative to the prior year.
The RPEC has not released a projection scale since MP-2021, citing complexities in incorporating the substantial number of “excess deaths” in 2020 and 2021 into their existing model and uncertainties about future expectations primarily related to COVID-19. As such, after considering the information released by the RPEC in October 2021 as well as the company’s recent mortality experience, we adopted the full MP-2021 projection scale while continuing to use the Pri-2012 White Collar table, supplemented with 50% of the Gradual Wear-Off illustration as outlined in the RPEC’s 2022 Mortality Improvement Update paper to reflect the future impacts of COVID-19, to develop our mortality assumptions used in calculating our pension and OPB obligations recognized at December 31, 2024, and the amounts estimated for our 2025 pension and OPB expense.
For further information regarding our pension and OPB plans, see “Risk Factors” and Notes 1 and 12 to the consolidated financial statements.
Litigation, Commitments and Contingencies
We are subject to a range of claims, disputes, enforcement actions, investigations, lawsuits, overhead cost claims, environmental matters, income tax matters and administrative proceedings that arise in the ordinary course of business. Estimating liabilities and costs associated with these matters requires judgment based upon the professional knowledge and experience of management. We determine whether to record a reserve and, if so, what amount based on consideration of the facts and circumstances of each matter as then known to us. Determinations regarding whether to record a reserve and, if so, of what amount, reflect management’s assessment regarding what is likely to occur; they do not necessarily reflect what management believes should occur. The ultimate resolution of any such exposure to us may vary materially from earlier estimates as further facts and circumstances develop or become known to us.
Environmental Matters - We are subject to environmental laws and regulations in the jurisdictions in which we do or have done business. Factors that could result in changes to the assessment of probability, range of reasonably estimated costs and environmental accruals include: modification of planned remedial actions; changes in the estimated time required to conduct remedial actions; discovery of more or less extensive (or different) contamination
NORTHROP GRUMMAN CORPORATION
than anticipated; information regarding the potential causes and effects of contamination; results of efforts to involve other responsible parties; financial capabilities of other responsible parties; changes in laws and regulations, their interpretation or application; contractual obligations affecting remediation or responsibilities; and improvements in remediation technology. As we expect to recover a significant portion of environmental remediation liabilities through overhead charges on government contracts, such amounts are deferred in prepaid expenses and other current assets (current portion) and other non-current assets until charged to contracts. We use judgment to evaluate the recoverability of our environmental remediation costs, assessing, among other things, U.S. government regulations, our U.S. government contract mix and past practices. Portions of the company’s environmental liabilities we do not expect to be recoverable have been expensed. As of December 31, 2024, we expect approximately 93 percent of the company’s environmental remediation costs to be recoverable; however, to the extent our judgments on the recoverability of our environmental remediation costs change or the unallowable portion of our environmental remediation costs otherwise increase, there could be a significant impact on our consolidated financial position, annual results of operations and/or cash flows.
Income Tax Matters - The evaluation of tax positions taken in a filed tax return, or planned to be taken in a future tax return or claim, requires the use of judgment. We establish reserves for uncertain tax positions when, despite the belief that our tax positions are supportable, there remains uncertainty in a tax position taken in our filed tax returns or planned to be taken in a future tax return or claim. The company follows a recognition and measurement approach, considering the facts, circumstances, and information available at the reporting date. We exercise judgment in determining the level of evidence necessary and appropriate to support our assessment using all available information. The technical merits of a given tax position are derived from sources of authority in the tax law and their applicability to the facts and circumstances of the position. In measuring the tax position, the company considers the amounts and probabilities of the outcomes that could be realized upon settlement. When it is more likely than not that a tax position will be sustained, we record the largest amount of tax benefit with a greater than 50 percent likelihood of being realized upon ultimate settlement with a taxing authority. As of December 31, 2024, we have approximately $1.4 billion in unrecognized tax benefits. To the extent we prevail in matters for which reserves have been established or are required to pay amounts in excess of reserves, there could be a significant impact on our consolidated financial position, annual results of operations and/or cash flows.
For further information on litigation, commitments and contingencies, see “Risk Factors” and Note 1, Note 6, Note 10 and Note 11 to the consolidated financial statements.
Goodwill and Long-Lived Assets
Overview - We allocate the purchase price of acquired businesses to the underlying tangible and intangible assets acquired and liabilities assumed based upon their respective fair values, with the excess recorded as goodwill. Such fair value assessments require judgments and estimates that can be affected by contract performance and other factors over time, which may cause final amounts to differ materially from original estimates. Adjustments to the fair value of purchased assets and liabilities after the initial measurement period are recognized in net earnings.
We record property, plant and equipment (PP&E) for capital assets used in operating our business. The cost of PP&E utilized in support of our government contracts is generally allowable and allocable cost in accordance with applicable FAR and CAS requirements, which limits our risk of impairment on those assets. However, the cost of PP&E utilized in support of our commercial business, including approximately $575 million of PP&E used in our commercial space business, is not allocable to government contracts and is therefore subject to greater recoverability risk.
Impairment Testing - We test for impairment of goodwill annually at each of our reporting units, which comprise our operating segments. The results of our annual goodwill impairment tests as of December 31, 2024 and 2023, respectively, indicated that the estimated fair value of each reporting unit significantly exceeded its respective carrying value. There were no impairment charges recorded in the years ended December 31, 2024, 2023 and 2022.
In addition to performing an annual goodwill impairment test, we may perform an interim impairment test if events occur or circumstances change that suggest goodwill in any of our reporting units may be impaired. Such indicators may include, but are not limited to, the loss of significant business, significant reductions in federal government appropriations or other significant adverse changes in industry or market conditions. During 2024, we determined there were no impairment indicators requiring us to perform an interim goodwill impairment test.
When testing goodwill for impairment, we compare the fair values of each of our reporting units to their respective carrying values. To determine the fair value of our reporting units, we primarily use the income approach based on the cash flows we expect the reporting units to generate in the future, consistent with our operating plans. This income valuation method requires management to project sales, operating expenses, working capital, capital
NORTHROP GRUMMAN CORPORATION
spending and cash flows for the reporting units over a multi-year period, as well as to determine the weighted-average cost of capital (WACC) used as a discount rate and terminal value assumptions. The WACC takes into account the relative weights of each component of our consolidated capital structure (equity and debt) and represents the expected cost of new capital adjusted as appropriate to consider lower risk profiles associated with longer-term contracts and barriers to market entry. The terminal value assumptions are applied to the final year of the discounted cash flow model. We use industry multiples (including relevant control premiums) of operating earnings to corroborate the fair values of our reporting units determined under the market valuation method of the income approach.
We test for impairment of our long-lived assets when events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable. Our assessment is based on our projection of the undiscounted future operating cash flows of the related asset group. If such projections indicate that future undiscounted cash flows are not sufficient to recover the carrying amount, we recognize a non-cash impairment charge to reduce the carrying amount to fair value. There were no impairment charges recorded in the years ended December 31, 2024, 2023 and 2022.
Impairment assessment inherently involves management judgments as to assumptions about expected future cash flows and the impact of market conditions on those assumptions. Due to the many variables inherent in developing the estimates used in our impairment analyses, differences in assumptions may have a material effect on the results of those impairment analyses.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Item 7A. Quantitative and Qualitative Disclosures About Market Risk
EQUITY RISK
We have been and continue to be exposed to market risk with respect to our portfolio of marketable securities with a fair value of $347 million at December 31, 2024. These securities are exposed to market volatilities, changes in price and interest rates.
INTEREST RATE RISK
We are exposed to interest rate risk on variable-rate short-term credit facilities for which there were no borrowings outstanding at December 31, 2024. At December 31, 2024, we have $16.3 billion of long-term debt, primarily consisting of fixed-rate debt, with a fair value of approximately $15.3 billion. The terms of our fixed-rate debt obligations do not generally allow investors to demand payment of these obligations prior to maturity. Therefore, we do not have significant exposure to interest rate risk for our fixed-rate debt; however, we do have exposure to fair value risk if we repurchase or exchange long-term debt prior to maturity. Additionally, if we were to refinance our long-term debt, it may be refinanced at higher interest rates.
FOREIGN CURRENCY RISK
In certain circumstances, we are exposed to foreign currency risk. We enter foreign currency forward contracts to manage a portion of the exchange rate risk related to receipts from customers and payments to suppliers denominated in foreign currencies. We do not hold or issue derivative financial instruments for trading purposes. At December 31, 2024, foreign currency forward contracts with a notional amount of $399 million were outstanding. At December 31, 2024, a 10 percent unfavorable foreign exchange rate movement would not have a material impact on our consolidated financial position, annual results of operations and/or cash flows.
INFLATION RISK
The global macroeconomic environment has experienced extraordinary challenges in recent years, including the highest rates of inflation in 40 years. The company, its subcontractors and other suppliers, have experienced, and may in the future experience, pressures from heightened levels of inflation and challenges from the macroeconomic environment. Certain of our fixed-price contracts include economic price adjustment (EPA) clauses to help protect the company against inflationary pressures. However, these EPA clauses may not be able to fully mitigate adverse impacts of rising inflation on the company’s financial position, results of operations and/or cash flows.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA
Item 8. Financial Statements and Supplementary Data
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Directors and Shareholders of
Northrop Grumman Corporation
Falls Church, Virginia
Opinion on the Financial Statements
We have audited the accompanying consolidated statements of financial position of Northrop Grumman Corporation and subsidiaries (the “Company”) as of December 31, 2024 and 2023, the related consolidated statements of earnings and comprehensive income, changes in shareholders’ equity, and cash flows for each of the three years in the period ended December 31, 2024, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024, in conformity with accounting principles generally accepted in the United States of America.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2024, based on the criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated January 29, 2025 expressed an unqualified opinion on the Company’s internal control over financial reporting.
Basis for Opinion
These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the 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 audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.

We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit and risk committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the 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.
Revenue Recognition - Estimates of Revenue and Cost at Completion for Select Long-Term Contracts - Refer to Note 1 to the financial statements
Critical Audit Matter Description
As further described in Note 1 to the financial statements, the Company recognizes revenue as control is transferred to the customer, which for long-term contracts is generally over-time using the cost-to-cost method (cost incurred relative to total cost estimated at completion). Use of the cost-to-cost-method requires the Company to make reasonably dependable estimates regarding the revenue and costs associated with the design, manufacture and delivery of their products or services. The Company estimates profit on these contracts as the difference between total estimated revenue and total estimated costs at completion and recognizes that profit as costs are incurred. We
NORTHROP GRUMMAN CORPORATION
analyzed the Company’s contract portfolio to identify contracts that we believe had elevated financial or performance risk. For those contracts identified, the evaluation of one or more of the assumptions used to recognize revenue required extensive audit effort due to the complexity of the contracts and a high degree of auditor judgment.
How the Critical Audit Matter Was Addressed in the Audit
Our audit procedures related to the revenue and cost estimates for these contracts identified included the following, among others:
•We tested the operating effectiveness of controls over the significant assumptions and judgments underlying the estimates of revenues and costs to completion associated with these long-term contracts.
•Based on the risk characteristic identified on an individual contract, we evaluated certain revenue and cost assumptions by:
-Reading the underlying contract and any amendments or modifications to understand the contractual requirements and performance obligations.
-Assessing the timing of recognition of any incentive fees or award fees based on contract terms and relevant historical trends.
-Evaluating management’s ability to achieve the estimates of remaining revenue and costs by performing inquiries with the Company’s program and business management regarding their basis of estimates including work plans, engineering specifications, program labor and suppliers, challenges or opportunities related to the program, actual performance to date compared to plan, and any recent correspondence between the Company and the customer on changes in scope or contractual terms.
-Evaluating selected changes to the estimates of costs to completion and obtaining supporting documentation on the appropriateness of the timing and amounts of these changes in estimates.
-Testing the accuracy and completeness of the information used in developing estimates, as well as the mathematical accuracy of management’s calculation of revenue recognized during the period for the performance obligations.

NORTHROP GRUMMAN CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Nature of Operations
Northrop Grumman Corporation is a leading global aerospace and defense technology company. We deliver a broad range of products, services and solutions to U.S. and international customers, and principally to the U.S. Department of Defense and intelligence community. Our broad portfolio is aligned to support national security priorities and our solutions equip our customers with capabilities they need to connect, protect and advance humanity.
The company is a leading provider of space systems, military aircraft, missile defense, advanced weapons and long-range fires capabilities, mission systems, networking and communications, strategic deterrence systems, and breakthrough technologies, such as advanced computing, microelectronics and cyber. We are focused on competing and winning programs that enable continued growth, performing on our commitments and affordably delivering capability our customers need. With the investments we've made in advanced technologies, combined with our talented workforce and digital transformation capabilities, Northrop Grumman is well positioned to meet our customers' needs today and in the future.
Principles of Consolidation and Reporting
The consolidated financial statements (the “financial statements”) include the accounts of Northrop Grumman and its subsidiaries and joint ventures or other investments for which we consolidate the financial results. Intercompany accounts, transactions and profits are eliminated in consolidation. Investments in equity securities and joint ventures where the company has significant influence, but not control, are accounted for using the equity method.
The financial statements are prepared in conformity with U.S. GAAP and in accordance with the rules of the SEC. The financial statements include adjustments of a normal recurring nature considered necessary by management for a fair presentation of the company’s consolidated financial position, results of operations and cash flows. For classification of certain current assets and liabilities, we consider the duration of our customer contracts when defining our operating cycle, which is generally longer than one year.
Effective July 1, 2024, the company realigned the Strategic Deterrent Systems (SDS) division, which includes the Ground-Based Strategic Deterrent (“Sentinel”) program, from Space Systems to Defense Systems. This realignment is reflected in the financial information contained in this report.
Subsequent Realignment - Effective January 1, 2025, the company realigned the Strike and Surveillance Aircraft Solutions (SSAS) business unit from Defense Systems to Aeronautics Systems. This realignment is not reflected in the financial information contained in this report; it will be reflected in the company’s operating results beginning in the first quarter of 2025.
Accounting Estimates
Preparation of the financial statements requires management to make estimates and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingencies at the date of the financial statements, as well as the reported amounts of sales and expenses during the reporting period. Estimates have been prepared using the most current and best available information; however, actual results could differ materially from those estimates.
Revenue Recognition
The majority of our sales are derived from long-term contracts with the U.S. government for the development or production of goods, the provision of services, or a combination of both. The company classifies sales as product or service based on the predominant attributes of each performance obligation.
The company recognizes revenue for each separately identifiable performance obligation in a contract representing a promise to transfer a distinct good or service to a customer. In most cases, goods and services provided under the company’s contracts are accounted for as single performance obligations due to the complex and integrated nature of our products and services. These contracts generally require significant integration of a group of goods and/or services to deliver a combined output. In some contracts, the company provides multiple distinct goods or services to a customer, most commonly when a contract covers multiple phases of the product life cycle (e.g., development, production, sustainment, etc.). In those cases, the company accounts for the distinct contract deliverables as separate performance obligations and allocates the transaction price to each performance obligation based on its relative standalone selling price, which is generally estimated using cost plus a reasonable margin. Warranties are provided on certain contracts, but do not typically provide for services beyond standard assurances and are therefore not considered to be separate performance obligations. Assets recognized from the costs to obtain or fulfill a contract are not material.
NORTHROP GRUMMAN CORPORATION
The company recognizes revenue as control is transferred to the customer, either over time or at a point in time. In general, our U.S. government contracts contain termination for convenience and/or other clauses that generally provide the customer rights to goods produced and/or in-process. Similarly, our non-U.S. government contracts generally contain contractual termination clauses or entitle the company to payment for work performed to date for goods and services that do not have an alternative use. For most of our contracts, control is effectively transferred during the period of performance, so we generally recognize revenue over time using the cost-to-cost method (cost incurred relative to total cost estimated at completion). The company believes this represents the most appropriate measurement towards satisfaction of its performance obligations. Revenue for contracts in which the control of goods produced does not transfer until delivery to the customer is recognized at a point in time (i.e., typically upon delivery).
Contracts are often modified for changes in contract specifications or requirements, which may result in scope and/or price changes. Most of the company’s contract modifications are for goods or services that are not distinct in the context of the contract and are therefore accounted for as part of the original performance obligation through a cumulative EAC adjustment.
Contract Estimates
Use of the cost-to-cost method requires us to make reasonably dependable estimates regarding the revenue and cost associated with the design, manufacture and delivery of our products and services. The company estimates profit on these contracts as the difference between total estimated sales and total estimated cost at completion and recognizes that profit as costs are incurred. Significant judgment is used to estimate total sales and cost at completion.
Contract sales may include estimates of variable consideration, including cost or performance incentives (such as award and incentive fees), un-priced change orders, REAs and contract claims. Variable consideration is included in total estimated sales to the extent it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. We estimate variable consideration as the most likely amount to which we expect to be entitled.
We recognize changes in estimated contract sales or costs and the resulting changes in contract profit on a cumulative basis. Cumulative EAC adjustments represent the cumulative effect of the changes on current and prior periods; sales and operating margins in future periods are recognized as if the revised estimates had been used since contract inception. If it is determined that a loss is expected to result on an individual performance obligation, the entire amount of the estimable future loss, including an allocation of G&A costs, is charged against income in the period the loss is identified.
B-21 Program
During the fourth quarter of 2023, we recognized a projected loss of $1.56 billion across the five LRIP options of the B-21 program. As of December 31, 2024, the remaining loss accrual is $1.3 billion, which is included in Other current liabilities.
Net EAC Adjustments
The following table presents the effect of aggregate net EAC adjustments:
Year Ended December 31
$ in millions, except per share data 2024 2023 2022
Revenue $ 396 $ 298 $ 447

Net earnings(1)
277 66 284
Diluted earnings per share(1)
1.88 0.43 1.83
(1)Based on a 21% federal statutory tax rate.
EAC adjustments on a single performance obligation can have a significant effect on the company’s financial statements. When such adjustments occur, we generally disclose the nature, underlying conditions and financial impact of the adjustments. During the third quarter of 2024, we recorded a $39 million favorable EAC adjustment on the HALO program at Space Systems related to the resolution of an engineering change proposal (ECP) as previously disclosed. During 2023, we recorded a $143 million unfavorable EAC adjustment on the first LRIP lot of the B-21 program at Aeronautics Systems and $100 million of unfavorable EAC adjustments on the HALO program at Space Systems. During 2022, we recorded $133 million of favorable EAC adjustments on the EMD phase of the
NORTHROP GRUMMAN CORPORATION
B-21 program at Aeronautics Systems. No other such adjustments were significant to the financial statements during the years ended December 31, 2024, 2023 and 2022.
Backlog
Backlog represents the future sales we expect to recognize on firm orders received by the company and is equivalent to the company’s remaining performance obligations at the end of each period. It comprises both funded backlog (firm orders for which funding is authorized and appropriated) and unfunded backlog. Unexercised contract options and IDIQ contracts are not included in backlog until the time an option or IDIQ task order is exercised or awarded.
Company backlog as of December 31, 2024 was $91.5 billion. Of our December 31, 2024 backlog, we expect to recognize approximately 40 percent as revenue over the next 12 months and 65 percent as revenue over the next 24 months, with the remainder to be recognized thereafter.
During 2024, the company reduced unfunded backlog by $1.6 billion and $0.7 billion related to terminations for convenience in our restricted space business and on the NGI program at Space Systems, respectively.
Contract Assets and Liabilities
For each of the company’s contracts, the timing of revenue recognition, customer billings, and cash collections results in a net contract asset or liability at the end of each reporting period. Fixed-price contracts are typically billed to the customer either using progress payments, whereby amounts are billed monthly as costs are incurred or work is completed, or performance based payments, which are based upon the achievement of specific, measurable events or accomplishments defined and valued at contract inception. Cost-type contracts are typically billed to the customer on a monthly or semi-monthly basis.
Contract assets are equivalent to and reflected as Unbilled receivables in the consolidated statements of financial position and are primarily related to long-term contracts where revenue recognized under the cost-to-cost method exceeds amounts billed to customers. Unbilled receivables are classified as current assets and include amounts that may be billed and collected beyond one year due to the long-cycle nature of many of our contracts. Accumulated contract costs in unbilled receivables include costs such as direct production costs, factory and engineering overhead, production tooling costs, and allowable G&A. Unbilled receivables also include certain estimates of variable consideration described above. These contract assets are not considered a significant financing component of the company’s contracts as the payment terms are intended to protect the customer in the event the company does not perform on its obligations under the contract.
Contract liabilities are equivalent to and reflected as Advance payments and billings in excess of costs incurred in the consolidated statements of financial position. Certain customers make advance payments prior to the company’s satisfaction of its obligations on the contract. These amounts are recorded as contract liabilities until such obligations are satisfied, either over time as costs are incurred or at a point in time when deliveries are made. Contract liabilities are not a significant financing component as they are generally utilized to pay for contract costs within a one-year period or are used to ensure the customer meets contractual requirements.
Net contract assets are as follows:
$ in millions December 31, 2024 December 31, 2023 $ Change % Change
Unbilled receivables, net $ 5,908 $ 5,693 $ 215 4 %
Advance payments and amounts in excess of costs incurred (4,070) (4,193) 123 (3) %
Net contract assets $ 1,838 $ 1,500 $ 338 23 %
Changes in the company’s contract assets and liabilities primarily result from timing differences between revenue recognition and customer billings and/or payments. Net contract assets as of December 31, 2024 increased 23 percent from the prior year, primarily due to the burn down of advances on certain Aeronautics Systems programs and an increase in unbilled receivables on several programs at Space Systems.
The amount of revenue recognized for the years ended December 31, 2024, 2023 and 2022 that was included in the contract liability balance at the beginning of each year was $3.6 billion, $3.1 billion and $2.4 billion, respectively.
Disaggregation of Revenue
See Note 15 for information regarding the company’s sales by customer type, contract type and geographic region for each of our segments. We believe those categories best depict how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors.
NORTHROP GRUMMAN CORPORATION
General and Administrative Expenses
In accordance with applicable FAR and CAS requirements, most general management and corporate expenses incurred at the segment and corporate locations are considered allowable and allocable costs to our U.S. government contracts. Allowable and allocable G&A costs, including independent research and development (IR&D) and bid and proposal (B&P) costs, are allocated on a systematic basis to contracts in progress and are included as a component of total estimated contract costs.
Research and Development
Company-sponsored research and development activities primarily include efforts related to government programs. Company-sponsored IR&D expenses totaled $1.1 billion, $1.2 billion and $1.2 billion in 2024, 2023 and 2022, respectively, which represented 2.7 percent, 3.0 percent and 3.3 percent of total sales, respectively. Customer-funded research and development activities are charged directly to the related contracts.
Income Taxes
Provisions for federal and foreign income taxes are calculated on reported earnings before income taxes based on current tax law and include the cumulative effect of any changes in tax rates from those used previously in determining deferred tax assets and liabilities. Such provisions differ from the amounts currently payable because certain items of income and expense are recognized in different periods for financial reporting purposes than for income tax purposes. The company recognizes federal and foreign interest accrued related to unrecognized tax benefits in income tax expense. Federal tax penalties are also recognized as a component of income tax expense.
In accordance with applicable FAR and CAS requirements, current state and local income and franchise taxes are generally considered allowable and allocable costs to our U.S. government contracts and are, therefore, recorded in operating costs and expenses. The company generally recognizes changes in deferred state taxes and unrecognized state tax benefits in unallocated corporate expenses.
Uncertain tax positions reflect the company’s expected treatment of tax positions taken in a filed tax return, or planned to be taken in a future tax return or claim. Until these positions are sustained by the taxing authorities or the statute of limitations concerning such issues lapses, the company does not generally recognize the tax benefits resulting from such positions and reports the tax effects as a liability for uncertain tax positions in its consolidated statements of financial position.
Cash and Cash Equivalents
Cash and cash equivalents are comprised of cash in banks and highly liquid instruments with original maturities of three months or less, primarily consisting of bank time deposits and investments in institutional money market funds. Cash in bank accounts often exceeds federally insured limits.
Fair Value of Financial Instruments
The company measures the fair value of its financial instruments using observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect internal market assumptions.
These two types of inputs create the following fair value hierarchy:
Level 1 - Quoted prices for identical instruments in active markets.
Level 2 - Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.
Level 3 - Significant inputs to the valuation model are unobservable.
The company holds a portfolio of marketable securities to partially fund non-qualified employee benefit plans. A portion of these securities are held in common/collective trust funds and are measured at fair value using NAV per share as a practical expedient. Marketable securities accounted for as trading are recorded at fair value on a recurring basis and are included in Other non-current assets in the consolidated statements of financial position. Changes in unrealized gains and losses on trading securities are included in Other, net in the consolidated statements of earnings and comprehensive income. Investments in held-to-maturity instruments with original maturities greater than three months are recorded at amortized cost.
Derivative financial instruments are recognized as assets or liabilities in the financial statements and measured at fair value on a recurring basis. Changes in the fair value of derivative financial instruments that are designated as fair value hedges are recorded in Other, net in the consolidated statements of earnings and comprehensive income, while changes in the fair value of derivative financial instruments that are designated as cash flow hedges are recorded as a
NORTHROP GRUMMAN CORPORATION
component of other comprehensive income until the hedged transaction is recognized in earnings. For derivative financial instruments not designated as hedging instruments, gains or losses resulting from changes in the fair value are reported in Other, net in the consolidated statements of earnings and comprehensive income.
The company uses derivative financial instruments to manage its exposure to foreign currency exchange risk related to receipts from customers and payments to suppliers denominated in foreign currencies (i.e., foreign currency forward contracts). For foreign currency forward contracts, where model-derived valuations are appropriate, the company utilizes the income approach to determine the fair value using internal models based on observable market inputs such as forward rates, interest rates, our own credit risk and our counterparties’ credit risks.
The company does not use derivative financial instruments for trading or speculative purposes, nor does it use leveraged financial instruments. Credit risk related to derivative financial instruments is considered minimal and is managed through the use of multiple counterparties with high credit standards and periodic settlements of positions, as well as by entering into master netting agreements with most of our counterparties.
Inventoried Costs
The company records inventoried costs at the lower of cost or net realizable value. Inventoried costs are categorized into raw materials, work in process, and finished goods. Raw materials are recognized using the average cost method and are generally included in contract cost when allocated to specific contracts. Work in process primarily consists of a) costs associated with specific anticipated contracts or costs incurred in excess of existing contract requirements, which are probable of recovery, and b) costs associated with unsatisfied performance obligations on contracts accounted for using point in time revenue recognition. Finished goods primarily consists of inventory maintained in support of sustainment contracts.
Inventoried costs include direct production costs, factory and engineering overhead, production tooling costs, and allowable G&A. G&A included in Inventoried costs, net was $100 million and $65 million as of December 31, 2024 and 2023, respectively. Inventoried costs are classified as current assets and include amounts related to contracts having production cycles longer than one year due to the long-cycle nature of our business.
Cash Surrender Value of Life Insurance Policies
The company maintains whole life and split-dollar life insurance policies primarily on former officers and executives. Whole life insurance policies are recorded at their cash surrender value as determined by the insurance carrier, and split-dollar life insurance policies are recorded at the lesser of their cash surrender value or premiums paid. These policies are utilized as a partial funding source for deferred compensation and other non-qualified employee retirement plans. As of December 31, 2024 and 2023, the carrying values associated with these policies were $416 million and $399 million, respectively, and are recorded in Other non-current assets in the consolidated statements of financial position.
Property, Plant and Equipment
Property, plant and equipment (PP&E) are depreciated over the estimated useful lives of individual assets. Machinery and other equipment is primarily depreciated using declining-balance methods. The other asset categories are generally depreciated using the straight-line method. Depreciation expense is generally an allowable and allocable cost in accordance with applicable FAR and CAS requirements and is recorded in the same segment where the related assets are held. However, the additional depreciation expense related to the step-up in fair value of PP&E acquired through business combinations is recorded in unallocated corporate expense within operating income as such depreciation is not allocable to government contracts and not considered part of management’s evaluation of segment operating performance. Major classes of PP&E and their useful lives are as follows:
NORTHROP GRUMMAN CORPORATION

During the fourth quarter of 2020, the company completed a sale of equipment to a customer on a restricted Aeronautics Systems program for $444 million. The company previously intended to use the equipment for internal purposes so we recognized the acquisition costs as capital expenditures and included the equipment in PP&E. As we regularly sell this type of equipment to customers in the ordinary course of business, we recorded the sale as a revenue transaction and included the net book value of the equipment in Operating costs and expenses. Although we generally classify proceeds from revenue transactions as cash inflows from operating activities, we recognized the proceeds from this transaction as cash inflows from investing activities, consistent with our prior recognition of the cost to acquire the equipment as capital expenditures. The company received the final cash payment of $155 million related to the equipment sale during 2022 and included it in Proceeds from sale of equipment to a customer in the consolidated statements of cash flows.
During the year ended December 31, 2022, the company acquired $46 million of internal use software through long-term financing directly with the supplier. The software was recorded in PP&E as a non-cash investing activity and the related liability was recorded in long-term debt as a non-cash financing activity. During the year ended December 31, 2023, the company received lease incentives for landlord funded leasehold improvements of $55 million related to Space Systems real estate leases, which were recorded in PP&E and included in non-cash investing activities.
On December 28, 2022 the company acquired certain leased land in exchange for company-owned land, which had been used previously for production-related activities at Space Systems. The exchange was accounted for as a nonmonetary transaction, and the acquired land, valued at approximately $155 million, was recorded in PP&E as a non-cash investing activity. The transaction resulted in a $96 million gain, which was reflected in operating costs and expenses in the consolidated statements of earnings and comprehensive income.
Non-cash investing activities also include capital expenditures incurred but not yet paid of $242 million, $75 million and $113 million as of December 31, 2024, 2023 and 2022, respectively.
Sale of Minority Investment
In July 2023, the company sold its minority investment in an Australian business for AUD $235 million (the equivalent of $157 million upon settlement). The sale resulted in a pre-tax gain of $97 million, which is reflected in Other, net on the consolidated statements of earnings and comprehensive income for the year ended December 31, 2023. Proceeds from the sale are included in investing activities on the consolidated statement of cash flows for the year ended December 31, 2023.
Goodwill and Other Purchased Intangible Assets
Goodwill and other purchased intangible asset balances are included in the identifiable assets of their assigned business segment. However, the company includes the amortization of other purchased intangible assets in unallocated corporate expense within operating income as such amortization is not allocable to government contracts and not considered part of management’s evaluation of segment operating performance. The company’s customer-related intangible assets are generally amortized over their respective useful lives based on the pattern in which the future economic benefits of the intangible assets are expected to be consumed. Other intangible assets are generally amortized on a straight-line basis over their estimated useful lives.
NORTHROP GRUMMAN CORPORATION
Leases
The company leases certain buildings, land and equipment. At contract inception, we determine whether a contract is or contains a lease and whether the lease should be classified as an operating or finance lease. Operating lease balances are included in Operating lease right-of-use assets, Other current liabilities, and Operating lease liabilities in our consolidated statements of financial position.
The company recognizes operating lease right-of-use assets and operating lease liabilities based on the present value of the future minimum lease payments over the lease term at commencement date. We use our incremental borrowing rate based on the information available at commencement date to determine the present value of future payments and the appropriate lease classification. Many of our leases include renewal options aligned with our contract terms. We define the initial lease term to include renewal options determined to be reasonably certain. We do not recognize a right-of-use asset and a lease liability for leases with an initial term of 12 months or less; we recognize lease expense for these leases on a straight-line basis over the lease term. We elected the practical expedient to not separate lease components from nonlease components and applied that practical expedient to all material classes of leased assets.
Many of the company’s real property lease agreements contain incentives for tenant improvements, rent holidays or rent escalation clauses. For tenant improvement incentives received, if the incentive is determined to be a leasehold improvement owned by the company, we generally record the incentives as a reduction to the right-of-use asset, which reduces rent expense over the lease term. For rent holidays and rent escalation clauses during the lease term, the company records rental expense on a straight-line basis over the term of the lease. For these lease incentives, the company uses the date of initial possession as the commencement date, which is generally when the company is given the right of access to the space and begins to make improvements in preparation for intended use.
Finance leases are not material to our consolidated financial statements and the company is not a lessor in any material arrangements. We do not have any material restrictions or covenants in our lease agreements, sale-leaseback transactions, land easements or residual value guarantees.
Litigation, Commitments and Contingencies
We accrue for litigation, commitments and contingencies when management, after considering the facts and circumstances of each matter as then known to management, has determined it is probable a liability will be found to have been incurred and the amount of the loss can be reasonably estimated. When only a range of amounts is reasonably estimable and no amount within the range is more likely than another, the low end of the range is recorded. Legal fees are generally expensed as incurred. Due to the inherent uncertainties surrounding gain contingencies, we generally do not recognize potential gains until realized.
Environmental Costs
We accrue for environmental liabilities when management determines that, based on the facts and circumstances known to the company, it is probable the company will incur costs to address environmental impacts and the costs are reasonably estimable. When only a range of amounts is reasonably estimable and no amount within the range is more likely than another, we record the low end of the range. The company typically projects environmental costs for up to 30 years, records environmental liabilities on an undiscounted basis, and excludes asset retirement obligations and certain legal costs. At sites involving multiple parties, we accrue environmental liabilities based upon our expected share of liability, considering the financial viability of other liable parties.
Retirement Benefits
The company sponsors various defined benefit pension plans and defined contribution retirement plans covering substantially all employees. In most cases, our defined contribution plans provide for a company match of employee contributions. The company also provides postretirement benefits other than pensions to eligible retirees and qualifying dependents, consisting principally of health care and life insurance benefits.
The liabilities, unamortized prior service credits and annual income or expense of the company’s defined benefit pension and OPB plans are determined using methodologies that involve several actuarial assumptions.
Because U.S. government regulations provide for the costs of pension and OPB plans to be charged to our contracts in accordance with applicable FAR and CAS requirements, we calculate retiree benefit plan costs under both FAS and CAS methods. While both FAS and CAS recognize a normal service cost component in measuring periodic pension cost, there are differences in the way the components of annual pension costs are calculated under each method. Measuring plan obligations under FAS and CAS also includes different assumptions and models, such as in estimating returns on plan assets, calculating interest expense and the periods over which gains/losses related to pension assets and actuarial changes are recognized. As a result, annual retiree benefit plan expense amounts for
NORTHROP GRUMMAN CORPORATION
FAS are different from the amounts for CAS in any given reporting period even though the ultimate cost of providing benefits over the life of the plans is the same under each method. CAS retiree benefit plan costs are charged to contracts and are included in segment operating income, and the difference between the service cost component of FAS expense and total CAS expense (the “FAS/CAS operating adjustment”) is recorded in operating income at the consolidated company level. Not all net periodic pension expense is recognized in net earnings in the year incurred because it is allocated as production costs and a portion remains in inventory at the end of any given reporting period.
Actuarial gains and losses are immediately recognized in net periodic benefit cost for FAS through MTM benefit (expense) upon annual remeasurement in the fourth quarter, or on an interim basis as triggering events warrant remeasurement. Prior service credits are recognized as a component of Accumulated other comprehensive loss and amortized into earnings in future periods.
Stock Compensation
The company’s stock compensation plans are classified as equity plans. Compensation expense for stock awards is measured at the grant date based on the fair value of the award and is recognized over the vesting period (generally three years), net of estimated forfeitures. The company issues stock awards in the form of restricted performance stock rights and restricted stock rights. The fair value of stock awards and performance stock awards is determined based on the closing market price of the company’s common stock on the grant date. The fair value of market-based stock awards is determined at the grant date using a Monte Carlo simulation model. For purposes of measuring compensation expense for performance awards, the number of shares ultimately expected to vest is estimated at each reporting date based on management’s expectations regarding the relevant performance criteria. At each reporting date, the number of shares used to calculate compensation expense and diluted earnings per share is adjusted to reflect the number ultimately expected to vest.
Accumulated Other Comprehensive Loss
The components of accumulated other comprehensive loss, net of tax, are as follows:

For all periods presented, the company had no material related party transactions.
Accounting Standards Updates
On November 27, 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2023-07 Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. Among other new disclosure requirements, ASU 2023-07 requires companies to disclose significant segment expenses that are regularly provided to the chief operating decision maker. We adopted the standard effective January 1, 2024 and applied the disclosure requirements retrospectively to all prior periods presented in the financial statements. Adoption of ASU 2023-07 did not have an impact on the company’s consolidated financial position, results of operations and/or cash flows.
On December 14, 2023, the FASB issued ASU No. 2023-09 Income Taxes (Topic 740): Improvements to Income Tax Disclosures. ASU 2023-09 requires companies to disclose, on an annual basis, specific categories in the effective tax rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. In addition, ASU 2023-09 requires companies to disclose additional information about income taxes paid. ASU 2023-09 will be effective for annual periods beginning January 1, 2025 and will be applied on a prospective basis with the option to apply the standard retrospectively. We are evaluating the disclosure impact of ASU 2023-09; however, the standard will not have an impact on the company’s consolidated financial position, results of operations and/or cash flows.
On November 4, 2024, the FASB issued ASU No. 2024-03 Disaggregation of Income Statement Expenses (Subtopic 220-40). ASU 2024-03 requires disaggregation of certain expense captions into specified categories in disclosures within the footnotes to the financial statements. ASU 2024-03 will be effective for annual periods beginning January 1, 2027 and interim periods beginning January 1, 2028 and will be applied on a prospective basis with the option to apply the standard retrospectively. We are evaluating the disclosure impact of ASU 2023-09; however, we do not
NORTHROP GRUMMAN CORPORATION
expect the standard will have a material impact on the company’s consolidated financial position, results of operations and/or cash flows.
Other accounting standards updates adopted and/or issued, but not effective until after December 31, 2024, are not expected to have a material effect on the company’s consolidated financial position, annual results of operations and/or cash flows.
2. EARNINGS PER SHARE, SHARE REPURCHASES AND DIVIDENDS ON COMMON STOCK
Basic Earnings Per Share
We calculate basic earnings per share by dividing net earnings by the weighted-average number of shares of common stock outstanding during each period.
Diluted Earnings Per Share
Diluted earnings per share include the dilutive effect of awards granted to employees under stock-based compensation plans. The dilutive effect of these securities totaled 0.3 million, 0.5 million and 0.7 million shares for the years ended December 31, 2024, 2023 and 2022, respectively.
Share Repurchases
Share Repurchase Programs
On January 25, 2021, the company’s board of directors authorized a share repurchase program of up to $3.0 billion in share repurchases of the company’s common stock (the “2021 Repurchase Program”). Repurchases under the 2021 Repurchase Program commenced in October 2021 and were completed in April 2023.
On January 24, 2022, the company’s board of directors authorized a new share repurchase program of up to an additional $2.0 billion in share repurchases of the company’s common stock (the “2022 Repurchase Program”). Repurchases under the 2022 Repurchase Program commenced in April 2023 and were completed in February 2024.
On December 6, 2023, the company’s board of directors authorized a new share repurchase program of up to an additional $2.5 billion in share repurchases of the company’s common stock (the “2023 Repurchase Program”). Repurchases under the 2023 Repurchase Program commenced in February 2024 upon completion of the 2022 Repurchase Program. As of December 31, 2024, repurchases under the 2023 Repurchase Program totaled $1.4 billion; $1.1 billion remained under this share repurchase authorization. By its terms, the 2023 Repurchase Program will expire when we have used all authorized funds for repurchases.
On December 11, 2024, the company’s board of directors authorized a new share repurchase program of up to an additional $3.0 billion in share repurchases of the company’s common stock (the “2024 Repurchase Program”). Repurchases under the 2024 Repurchase Program will commence upon completion of the 2023 Repurchase Program and will expire when we have used all authorized funds for repurchases. As of December 31, 2024, there have been no repurchases under the 2024 Repurchase Program and the company’s total outstanding share repurchase authorization was $4.1 billion.
Accelerated Share Repurchase Agreements
During the first quarter of 2023, the company entered into an accelerated share repurchase (ASR) agreement with Bank of America, N.A. (Bank of America) to repurchase $500 million of the company’s common stock as part of the 2021 and 2022 Repurchase Programs. Under the agreement, we made a payment of $500 million to Bank of America and received an initial delivery of 0.9 million shares valued at $400 million that were immediately canceled by the company. The remaining balance of $100 million was settled on April 27, 2023 with a final delivery of 0.2 million shares from Bank of America. The final average purchase price was $458.28 per share.
During the first quarter of 2024, the company entered into an ASR agreement with Morgan Stanley & Co. LLC (Morgan Stanley) to repurchase $1.0 billion of the company’s common stock as part of the 2022 Repurchase Program. Under the agreement, we made a payment of $1.0 billion to Morgan Stanley and received an initial delivery of 1.8 million shares valued at $800 million that were immediately canceled by the company. The remaining balance of $200 million was settled on May 1, 2024 with a final delivery of 0.4 million shares from Morgan Stanley. The final average purchase price was $455.73 per share.
Share repurchases take place from time to time, subject to market and regulatory conditions and management’s discretion, in the open market or in privately negotiated transactions. The company retires its common stock upon repurchase and, in the periods presented, has not made any purchases of common stock other than in connection with these publicly announced repurchase programs.

3. ACCOUNTS RECEIVABLE, NET
Accounts receivable, net represent amounts billed and due from customers. Substantially all accounts receivable at December 31, 2024 are expected to be collected in 2025. The company does not believe it has significant exposure to credit risk as the majority of our accounts receivable are due from the U.S. government either as the ultimate customer or in connection with foreign military sales.
Accounts receivable, net consisted of the following:
December 31

(1)Includes receivables due from the U.S. government associated with foreign military sales, which are contracted with and paid by the U.S. government.
4. UNBILLED RECEIVABLES, NET
Unbilled receivables, net represent revenue recognized under the cost-to-cost method that exceeds amounts billed to customers. A large majority of the company’s unbilled receivables at December 31, 2024 are expected to be billed and collected in 2025. Progress and performance-based payments are reflected as an offset to the related unbilled receivable balances.

5. INVENTORIED COSTS, NET
Inventoried costs are principally associated with contracts where the U.S. government is the primary customer, therefore the company does not believe it has significant exposure to recoverability risk related to these amounts. Inventoried costs associated with our commercial businesses, while less significant in total, are subject to a greater level of recoverability risk.
Inventoried costs, net consisted of the following:

Finished goods 44 52
Inventoried costs, net $ 1,455 $ 1,109
Inventoried costs, net increased $346 million, or 31 percent, largely due to an increase in costs incurred for specific anticipated contracts to reduce customer delivery lead times.
The company recorded write-downs of commercial business inventory at Space Systems for which its cost exceeded net realizable value of $43 million during the year ended December 31, 2023. In addition, the company recognized a $45 million reduction of inventoried costs related to the B-21 program at Aeronautics Systems during the year ended December 31, 2023.

6. INCOME TAXES
Federal and foreign income tax expense consisted of the following:
Year Ended December 31
$ in millions 2024 2023 2022
Federal income tax expense:
Current $ 628 $ 949 $ 1,289

Total foreign income tax expense 10 11 4
Total federal and foreign income tax expense $ 842 $ 290 $ 940
Earnings before income taxes associated with the company’s foreign operations are not material in the periods presented.
Income tax expense differs from the amount computed by multiplying earnings before income taxes by the statutory federal income tax rate due to the following:
Year Ended December 31
$ in millions 2024 2023 2022
Income tax expense at statutory rate $ 1,053 21.0 % $ 493 21.0 % $ 1,226 21.0 %
Research credit (361) (7.2) (210) (8.9) (177) (3.0)
Foreign derived intangible income 13 0.3 (63) (2.7) (66) (1.1)

Total federal and foreign income taxes $ 842 16.8 % $ 290 12.4 % $ 940 16.1 %
The 2024 ETR increased to 16.8 percent from 12.4 percent in 2023 primarily due to the impact of the prior year B-21 charge and the MTM adjustment on our ETR. The 2024 MTM benefit increased the 2024 ETR by 0.4 percentage points, whereas the prior year B-21 charge and MTM expense collectively reduced the 2023 ETR by 3.8 percentage points. The 2024 ETR also reflects a net reduction in tax reserves largely due to a recent federal court decision, partially offset by higher interest expense on unrecognized tax benefits.
The 2023 ETR decreased to 12.4 percent from 16.1 percent in 2022 primarily due to lower earnings before income taxes as a result of the B-21 charge and MTM expense, which collectively reduced the 2023 ETR by 3.8 percentage points. The 2022 MTM benefit increased the 2022 ETR by 1.2 percentage points.
Income tax payments, net of refunds received, were $880 million, $1.2 billion and $1.5 billion for the years ended December 31, 2024, 2023 and 2022, respectively. Taxes receivable, which are included in Prepaid expenses and other current assets in the consolidated statements of financial position, were $517 million and $1.5 billion as of December 31, 2024 and 2023, respectively.
Net interest expense within the company’s federal, foreign and state income tax provisions was $164 million, $62 million, and $29 million for the years ended December 31, 2024, 2023, and 2022, respectively.
The Organization for Economic Co-operation and Development issued Pillar Two model rules for a global minimum tax of 15% effective January 1, 2024. While it is uncertain whether the United States will enact legislation to adopt Pillar Two, certain countries in which we operate have adopted legislation, and other countries are in the process of introducing legislation to implement Pillar Two. Pillar Two had no impact on our 2024 ETR, and we do not currently expect Pillar Two to significantly impact our ETR going forward.
NORTHROP GRUMMAN CORPORATION
Uncertain Tax Positions
We file income tax returns in the U.S. federal jurisdiction and in various state and foreign jurisdictions. During the fourth quarter of 2024, the company entered into an agreed RAR for certain matters related to the company’s 2018-2020 federal income tax returns, largely related to our methods of accounting associated with the timing of revenue recognition and related costs under IRC Section 451(b), resulting in a $766 million reduction to our unrecognized tax benefits and an immaterial impact to income tax expense. The matters not addressed by the agreed RAR related to the company’s 2018-2020 federal tax returns are currently under Internal Revenue Service (IRS) examination.
During the second quarter of 2023, the company entered into an agreed RAR for certain matters related to the company’s 2014-2017 federal income tax returns, resulting in a $90 million reduction to our unrecognized tax benefits and an immaterial impact to income tax expense. The matters not addressed by the agreed RAR related to the company’s 2014-2017 federal income tax returns and refund claims related to its 2007-2016 federal tax returns are currently under review by the IRS Appeals Office.
In the second quarter of 2023, the California Franchise Tax Board approved a resolution of the state examination primarily related to California state apportionment in the company’s 2007 to 2016 tax years, resulting in a $95 million reduction to our unrecognized tax benefits and an $11 million reduction to unallocated corporate expense.
Tax returns for open tax years related to state and foreign jurisdictions remain subject to examination. As state income taxes are generally considered allowable and allocable costs, any individual or aggregate state examination impacts are not expected to have a material impact on our financial results. Amounts currently subject to examination related to foreign jurisdictions are not material.
The company’s unrecognized tax benefits, excluding accrued interest and penalties of $373 million, $305 million and $216 million as of December 31, 2024, 2023 and 2022, respectively, are presented below:
December 31
$ in millions 2024 2023 2022
Unrecognized tax benefits at beginning of the year $ 1,994 $ 1,663 $ 1,630
Additions based on tax positions related to the current year 236 276 262
Additions for tax positions of prior years 90 254 6
Reductions for tax positions of prior years (106) (9) (124)
Settlements with taxing authorities (766) (189) (110)
Other, net (1) (1) (1)
Net change in unrecognized tax benefits (547) 331 33
Unrecognized tax benefits at end of the year $ 1,447 $ 1,994 $ 1,663
The 2024 decrease in unrecognized tax benefits was primarily related to the settlement of certain matters related to the company’s methods of accounting associated with the timing of revenue recognition under IRC Section 451(b) as discussed above, partially offset by additional reserves on current year tax positions related to 451(b) (prior to settlement) and research credits. It is reasonably possible that within the next 12 months the company’s unrecognized tax benefits may increase by approximately $100 million.
If the income tax benefits from these tax positions are ultimately realized, $914 million of federal and foreign tax benefits would reduce the company’s ETR.
Inclusive of accrued interest and penalties, the company’s current unrecognized tax benefits of $345 million and $964 million as of December 31, 2024 and 2023, respectively, are included in Other current liabilities in the consolidated statements of financial position.

Deferred Income Taxes
Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and tax purposes. Net deferred tax assets and liabilities are classified as non-current in the consolidated statements of financial position.

Realization of deferred tax assets is primarily dependent on generating sufficient taxable income in future periods. The company believes it is more-likely-than-not our net deferred tax assets will be realized.
At December 31, 2024, the company has available tax credits and unused net operating losses of $627 million and $318 million, respectively, that may be applied against future taxable income. The majority of tax credits and net operating losses expire between 2025 and 2047, however, some may be carried forward indefinitely. Due to the uncertainty of the realization of the tax credits and net operating losses, the company has recorded valuation allowances of $343 million and $42 million, respectively, as of December 31, 2024.

As of December 31, 2024, the company has accumulated undistributed earnings generated by our foreign subsidiaries and most have been taxed in the U.S. We intend to indefinitely reinvest these earnings, as well as future earnings from our foreign subsidiaries to fund our international operations. In addition, we expect future U.S. cash generation will be sufficient to meet future U.S. cash needs.

9. DEBT
Commercial Paper
The company maintains a commercial paper program that serves as a source of short-term financing with capacity to issue unsecured commercial paper notes up to $2.5 billion. There were no commercial paper borrowings outstanding at December 31, 2024 and December 31, 2023, respectively.
Credit Facility
The company maintains a five-year senior unsecured credit facility in an aggregate principal amount of $2.5 billion (the “2022 Credit Agreement”) that matures in August 2027. The revolving credit facility established under the 2022 Credit Agreement is intended to support the company’s commercial paper program and other general corporate purposes. Commercial paper borrowings reduce the amount available for borrowing under the 2022 Credit Agreement. At December 31, 2024, there were no borrowings outstanding under this facility.
The 2022 Credit Agreement contains generally customary terms and conditions, including covenants restricting the company’s ability to sell all or substantially all of its assets, merge or consolidate with another entity or undertake other fundamental changes and incur liens. The company also cannot permit the ratio of its debt to capitalization (as set forth in the credit agreement) to exceed 65 percent. At December 31, 2024, the company was in compliance with all covenants under its credit agreement.
Unsecured Senior Notes
Issuance of Senior Notes
In January 2024, the company issued $2.5 billion of unsecured senior notes for general corporate purposes, including debt repayment, share repurchases, and working capital, as follows:
•$500 million of 4.60% senior notes due 2029 (the “2029 Notes”),
•$850 million of 4.90% senior notes due 2034 (the “2034 Notes”), and
•$1.15 billion of 5.20% senior notes due 2054 (the “2054 Notes”).
In February 2023, the company issued $2.0 billion of unsecured senior notes for general corporate purposes, including debt repayment, share repurchases, and working capital, as follows:
•$1.0 billion of 4.70% senior notes due 2033 (the “2033 Notes”) and
•$1.0 billion of 4.95% senior notes due 2053 (the “2053 Notes”).
We refer to the 2029 Notes, 2033 Notes, 2034 Notes, 2053 Notes and 2054 Notes, together, as the “notes.” Interest on the notes is payable semi-annually in arrears. The notes are generally subject to redemption, in whole or in part, at the company’s discretion at any time, or from time to time, prior to maturity at a redemption price equal to the greater of 100% of the principal amount of the notes to be redeemed or an applicable “make-whole” amount, plus accrued and unpaid interest.
NORTHROP GRUMMAN CORPORATION
Repayments of Senior Notes
In August 2023, the company repaid $1.05 billion of 3.25 percent unsecured senior notes upon maturity.
Subsequent Event - In January 2025, the company repaid $1.5 billion of 2.93 percent unsecured senior notes upon maturity.

The estimated fair value of long-term debt was $15.3 billion and $13.4 billion as of December 31, 2024 and 2023, respectively. We calculated the fair value of long-term debt using Level 2 inputs, based on interest rates available for debt with terms and maturities similar to the company’s existing debt arrangements.
Indentures underlying long-term debt issued by the company or its subsidiaries contain various restrictions with respect to the issuer, including one or more restrictions relating to limitations on liens, sale-leaseback arrangements and funded debt of subsidiaries. The majority of these fixed rate notes and debentures are subject to redemption at the company’s discretion at any time prior to maturity in whole or in part at the principal amount plus any make-whole premium and accrued and unpaid interest. Interest on these fixed rate notes and debentures are payable semi-annually in arrears.
Total interest payments, net of interest received and capitalized, were $475 million, $437 million and $474 million for the years ended December 31, 2024, 2023 and 2022, respectively. The company capitalized interest expense of $113 million, $95 million and $53 million during the years ended December 31, 2024, 2023 and 2022, respectively.

10. INVESTIGATIONS, CLAIMS AND LITIGATION
For over 25 years, the company has worked closely with the United States Navy, the United States Environmental Protection Agency, the New York State Department of Environmental Conservation, the New York State Department of Health and other federal, state and local governmental authorities, to address environmental conditions allegedly resulting from historic operations at the former United States Navy and Grumman facilities in Bethpage, New York. We have incurred, and expect to continue to incur, as included in Note 11, substantial remediation costs related to these Bethpage environmental conditions, including potential costs relating to unanticipated developments such as new discoveries of potential contaminants. It is also possible that applicable remediation standards and other requirements to which we are subject may continue to change, and that our costs may increase materially. In 2022, we resolved several disputes and regulatory proceedings concerning the scope and allocation of remediation responsibilities and costs related to this site and we continue remediation consistent with agreements through which those disputes were resolved. The company continues to be involved in other remediation-related disputes, none of which are material individually or in the aggregate. We are also a party to various individual lawsuits and a putative class action in the Eastern District of New York alleging personal injury and property damage related to the legacy Bethpage environmental conditions (the “Bethpage EDNY cases”). The court has stayed the filed individual lawsuits, pending its decision on class certification, which the court will undertake if an ongoing mediation between the parties is unsuccessful. We are also a party, and may become a party, to other lawsuits brought by or against insurance carriers, and by other individual plaintiffs and/or putative classes, as well as other parties. We cannot at this time predict or reasonably estimate the potential outcomes or ranges of possible liability of the Bethpage EDNY cases.
The company received from the U.S. Department of Justice (DOJ) a criminal subpoena on December 9, 2022, and a civil investigative demand (CID) on February 2, 2023, both seeking information regarding financial and cost accounting and controls that appears focused on the interest rate assumptions the company used to determine our U.S. Government Cost Accounting Standards (CAS) pension expense, which we discuss in Note 11 below. The company is engaging with the government and responding to the requests. We cannot at this point predict the outcome of these matters.
The company is a party to various other investigations, lawsuits, arbitration, claims, enforcement actions and other legal proceedings, including government investigations and claims, that arise in the ordinary course of our business. The nature of legal proceedings is such that we cannot assure the outcome of any particular matter. However, based on information available to the company to date, the company does not believe that the outcome of any of these other matters pending against the company is likely to have a material adverse effect on the company’s consolidated financial position as of December 31, 2024, or its annual results of operations and/or cash flows.
11. COMMITMENTS AND CONTINGENCIES
U.S. Government Cost Claims and Contingencies
From time to time, the company is advised of claims by the U.S. government concerning certain potential disallowed costs, plus, at times, penalties and interest. When such findings are presented, the company and U.S. government representatives engage in discussions to enable the company to evaluate the merits of these claims, as well as to
NORTHROP GRUMMAN CORPORATION
assess the amounts being claimed. Where appropriate, provisions are made to reflect the company’s estimated exposure for such potential disallowed costs. Such provisions are reviewed periodically using the most recent information available. The company believes it has adequately reserved for disputed amounts that are probable and reasonably estimable, and that the outcome of any such matters would not have a material adverse effect on its consolidated financial position as of December 31, 2024, or its annual results of operations and/or cash flows.
In 2019, the Defense Contract Management Agency (DCMA) raised questions about an interest rate assumption used by the company to determine our CAS pension expense. On June 1, 2020, DCMA provided written notice that the assumptions the company used during the period 2013-2019 were potentially noncompliant with CAS. We submitted a formal response on July 31, 2020, which we believed demonstrates the appropriateness of the assumptions used. On November 24, 2020, DCMA replied to the company’s response, disagreeing with our position and requesting additional input, which we provided on February 22, 2021. We subsequently continued to exchange correspondence and engage with DCMA on this matter, including responding to requests for and providing additional information. On February 15, 2024, DCMA sent to the company a Contracting Officer’s determination of noncompliance with CAS, which is an interim, non-final determination, and the parties engaged in discussions. As noted in Note 10 above, the company received from the DOJ a criminal subpoena on December 9, 2022 and a CID on February 2, 2023, both seeking information that appears related to the interest rate assumptions at issue in our discussions with DCMA. The company has responded to requests and expects to continue discussions with the DOJ and DCMA as these matters progress. We cannot at this point predict the outcome of these matters. The sensitivity to changes in interest rate assumptions makes it reasonably possible the outcome of the DCMA matter could have a material adverse effect on our financial position, results of operations and/or cash flows, although we are not currently able to estimate a range of any potential loss.
Environmental Matters
The table below summarizes the amount accrued for environmental remediation costs, management’s estimate of the amount of reasonably possible future costs in excess of accrued costs and the deferred costs expected to be recoverable through overhead charges on U.S. government contracts as of December 31, 2024 and 2023:
$ in millions Accrued Costs(1)(2)
Reasonably Possible Future Costs in Excess of Accrued Costs(2)
Deferred Costs(3)
December 31, 2024 $ 546 $ 377 $ 507
December 31, 2023 584 387 518
(1)As of December 31, 2024, $196 million is recorded in Other current liabilities and $350 million is recorded in Other non-current liabilities.
(2)Estimated remediation costs are not discounted to present value. The reasonably possible future costs in excess of accrued costs do not take into consideration amounts expected to be recoverable through overhead charges on U.S. government contracts.
(3)As of December 31, 2024, $186 million is deferred in Prepaid expenses and other current assets and $321 million is deferred in Other non-current assets. These amounts reflect a $26 million increase during the second quarter of 2024 in our estimated recovery of certain environmental remediation costs and are evaluated for recoverability on a routine basis.
Although management cannot predict whether (i) new information gained as our environmental remediation projects progress, (ii) changes in remediation standards or other requirements to which we are subject, or (iii) other changes in facts and circumstances will materially affect the estimated liability accrued, we do not anticipate that future remediation expenditures associated with our currently identified projects will have a material adverse effect on the company’s consolidated financial position as of December 31, 2024, or its annual results of operations and/or cash flows.
Financial Arrangements
In the ordinary course of business, the company uses standby letters of credit and guarantees issued by commercial banks and surety bonds issued principally by insurance companies to guarantee the performance on certain obligations. At December 31, 2024, there were $484 million of stand-by letters of credit and guarantees and $272 million of surety bonds outstanding.
Indemnifications
The company has provided indemnifications for certain environmental, income tax and other potential liabilities in connection with certain of its divestitures. The settlement of these liabilities is not expected to have a material
NORTHROP GRUMMAN CORPORATION
adverse effect on the company’s consolidated financial position as of December 31, 2024, or its annual results of operations and/or cash flows.
12. RETIREMENT BENEFITS
Plan Descriptions
U.S. Defined Benefit Pension Plans - The company sponsors several defined benefit pension plans in the U.S. Pension benefits for most participants are based on years of service, age and compensation. It is our policy to fund at least the minimum amount required for qualified plans, using actuarial cost methods and assumptions acceptable under U.S. government regulations, by making payments into benefit trusts separate from the company.
U.S. Defined Contribution Plans - The company also sponsors defined contribution plans covering the majority of its employees, including certain employees covered under collective bargaining agreements. Company contributions vary depending on date of hire, with a majority of employees being eligible for employer matching of employee contributions. Based on date of hire, certain employees are eligible to receive a company non-elective contribution or an enhanced matching contribution in lieu of a defined benefit pension plan benefit. The company’s contributions to these defined contribution plans for the years ended December 31, 2024, 2023 and 2022, were $657 million, $634 million and $558 million, respectively.
Non-U.S. Benefit Plans - The company sponsors several benefit plans for non-U.S. employees. These plans are designed to provide benefits appropriate to local practice and in accordance with local regulations. Some of these plans are funded using benefit trusts separate from the company.
Medical and Life Benefits - The company funds a portion of the costs for certain health care and life insurance benefits for a substantial number of its active and retired employees. In addition to a company and employee cost-sharing feature, the health plans also have provisions for deductibles, co-payments, coinsurance percentages, out-of-pocket limits, conformance to a schedule of reasonable fees, the use of managed care providers and coordination of benefits with other plans. The plans also provide for a Medicare carve-out. The company reserves the right to amend or terminate the plans at any time.
Certain covered employees and dependents are eligible to participate in plans upon retirement if they meet specified age and years of service requirements. The company provides subsidies to reimburse certain retirees for a portion of the cost of individual Medicare-supplemental coverage purchased directly by the retiree through a private insurance exchange. The company has capped the amount of its contributions for substantially all its remaining postretirement medical and life benefit plans. In addition, after January 1, 2005 (or earlier at some businesses), newly hired employees are not eligible for subsidized postretirement medical and life benefits.

The decrease in the fair value of plan assets for the year ended December 31, 2024 was principally driven by $2.1 billion of benefit payments, partially offset by net returns on plan assets of 4.7 percent. The decrease in our projected benefit obligation for the year ended December 31, 2024, was primarily driven by $2.1 billion of benefit payments and a 58 basis point increase in the discount rate from year end 2023, partially offset by $1.6 billion of interest cost.

Plan Assets and Investment Policy
Plan assets are invested in various asset classes that are expected to produce a sufficient level of diversification and investment return over the long term. Liability studies are conducted on a regular basis to provide guidance in setting investment goals with an objective to balance risk. Risk targets are established and monitored against acceptable ranges.
Our investment policies and procedures are designed to ensure the plans’ investments comply with ERISA. Guidelines are established defining permitted investments within each asset class. Derivatives are used for transitioning assets, asset class rebalancing, managing currency risk and for management of fixed-income and alternative investments.
NORTHROP GRUMMAN CORPORATION
For the majority of the plans’ assets, the investment policies require that the asset allocation be maintained within the following ranges as of December 31, 2024:
Asset Allocation Ranges
Cash and cash equivalents 0% - 12%
Global public equities 18% - 38%
Fixed-income securities 35% - 55%

NORTHROP GRUMMAN CORPORATION
Generally, investments are valued based on information in financial publications of general circulation, statistical and valuation services, records of security exchanges, appraisal by qualified persons, transactions and bona fide offers. Cash and cash equivalents are predominantly held in money market or short-term investment funds. U.S. and international equities consist primarily of common stocks and institutional common trust funds. Investments in certain equity securities, which include domestic and international securities and registered investment companies, and exchange-traded funds with fixed income strategies are valued at the last reported sales or quoted price on the last business day of the reporting period. Fair values for certain fixed-income securities, which are not exchange-traded, are valued using third-party pricing services.
Derivatives and other assets include derivative assets with a fair value of $107 million and $172 million, derivative liabilities with a fair value of $123 million and $101 million, and net notional amounts of $9.2 billion and $4.9 billion, as of December 31, 2024 and 2023, respectively. Derivative instruments may include exchange traded futures contracts, interest rate swaps, options on futures and swaps, currency contracts, total return swaps and credit default swaps. Notional amounts do not quantify risk or represent assets or liabilities of the pension and VEBA trusts, but are used in the calculation of cash settlement under the contracts. Certain derivative financial instruments within the pension trust are subject to master netting agreements with certain counterparties.
Investments in certain equity and fixed-income funds, which include common/collective trust funds, and alternative investments, including hedge funds, opportunistic investments, private equity funds and real estate funds, are valued based on the NAV derived by the investment managers, as a practical expedient, and are described further below.
U.S. and International equities: Generally, redemption periods are daily, monthly or quarterly with a notice requirement less than 90 days. As of December 31, 2024 and 2023, there were no unfunded commitments.
Fixed-income funds: Generally, redemption periods are daily, monthly or quarterly with a notice requirement of two days. As of December 31, 2024 and 2023 there were no unfunded commitments.

Private equity funds: The term of each fund is typically 10 or more years and the fund’s investors do not have an option to redeem their interest in the fund. As of December 31, 2024 and 2023, unfunded commitments were $1.6 billion and $1.9 billion, respectively.
Real estate funds: Consist primarily of open-end funds that generally allow investors to redeem their interests in the funds. Certain closed-end real estate funds have terms of 10 or more years. As of December 31, 2024 and 2023, unfunded commitments were $24 million and $28 million, respectively.

13. STOCK COMPENSATION PLANS AND OTHER COMPENSATION ARRANGEMENTS
Stock Compensation Plans
At December 31, 2024, the company had stock-based compensation awards outstanding under the following shareholder-approved plans: the 2024 Long-Term Incentive Stock Plan (2024 Plan) and the 2011 Long-Term Incentive Stock Plan (2011 Plan), both applicable to employees and non-employee directors, and the 1993 Stock Plan for Non-Employee Directors (1993 SPND).
Employee Plans - On May 15, 2024, the company’s shareholders approved the company’s new 2024 Plan, which replaced the 2011 Plan. The 2024 Plan authorized 5.75 million new shares (less the number of shares subject to any new awards under the 2011 Plan between March 1 and May 15, 2024). Under the terms of the 2024 Plan, in the event outstanding awards under the 2011 Plan expire or terminate without being exercised or paid, as the case may be, such forfeited shares will become available for award under the 2024 Plan and increase the authorization. As of December 31, 2024, 5.8 million shares remain available for issuance under the 2024 Plan.
The 2011 Plan provided for and the 2024 Plan provides for the following equity awards: stock options, stock appreciation rights (SARs) and stock awards. Under the 2011 Plan and 2024 Plan, no SARs have been granted and there are no outstanding stock options. Stock awards include restricted performance stock rights (RPSR) and restricted stock rights (RSR). RPSRs generally vest and are paid following the completion of a three-year performance period, based primarily on achievement of certain performance metrics determined by the Board. RSRs generally vest 100% after three years. Each includes dividend equivalents, which are paid concurrently with the RPSR or RSR. The terms of equity awards granted under the 2011 Plan and 2024 Plan provide for accelerated vesting, and in some instances forfeiture, of all or a portion of an award upon termination of employment.
Non-Employee Director Plans - Awards to non-employee directors are made pursuant to the Northrop Grumman Corporation Equity Grant Program for Non-Employee Directors (the Director Program). The Director Program was amended and restated effective January 1, 2016 (the Amended Director Program). The Director Program was again amended and restated effective May 15, 2024, consistent with the shareholder-approved 2024 Plan (the Restated Director Program). Under the Restated Director Program, each non-employee director is awarded an annual equity grant in the form of Automatic Stock Units, which vest on the one-year anniversary of the annual shareholder meeting. Directors may elect to have all or any portion of their Automatic Stock Units paid on (A) the earlier of (i) the beginning of a specified calendar year after the vesting date or (ii) their separation from service as a member of the Board, or (B) on the vesting date.
Directors also may elect to defer to a later year all or a portion of their remaining cash retainer or committee retainer fees into a stock unit account as Elective Stock Units or in alternative investment options. Elective Stock Units are awarded on a quarterly basis. Directors may elect to have all or a portion of their Elective Stock Units paid on the earlier of (i) the beginning of a specified calendar year or (ii) their separation from service as a member of the Board. Stock units awarded under the Amended Director Program and Restated Director Program are paid out in an equivalent number of shares of Northrop Grumman common stock. Directors are credited with dividend equivalents
NORTHROP GRUMMAN CORPORATION
in connection with the accumulated stock units until the shares of common stock relating to such stock units are issued.

15. SEGMENT INFORMATION
The company is aligned in four operating sectors, which also comprise our reportable segments: Aeronautics Systems, Defense Systems, Mission Systems and Space Systems. We generally organize our segments based on the nature of products and services offered.
The company’s chief operating decision maker (“CODM”) is the Chair, Chief Executive Officer and President. The CODM is responsible for allocating resources and assessing performance of the consolidated enterprise and operating sectors. The profitability measure the CODM uses to assess segment performance and allocate resources is segment operating income (and related margin rate, calculated as segment operating income divided by sales) by comparing historical, actual, and forecasted amounts on a regular basis.

NORTHROP GRUMMAN CORPORATION
Unallocated Corporate (Expense) Income
Unallocated corporate (expense) income includes the portion of corporate costs not considered allowable or allocable under applicable FAR and CAS requirements, and therefore not allocated to the segments, such as changes in deferred state income taxes and a portion of management and administration, legal, environmental, compensation, retiree benefits, advertising and other corporate unallowable costs. Unallocated corporate (expense) income also includes costs not considered part of management’s evaluation of segment operating performance, such as amortization of purchased intangible assets and the additional depreciation expense related to the step-up in fair value of PP&E acquired through business combinations, as well as certain compensation and other costs.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING
The management of Northrop Grumman Corporation (the company) prepared and is responsible for the consolidated financial statements and all related financial information contained in this Annual Report. This responsibility includes establishing and maintaining effective internal control over financial reporting. The company’s internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America.
To comply with the requirements of Section 404 of the Sarbanes-Oxley Act of 2002, the company designed and implemented a structured and comprehensive assessment process to evaluate its internal control over financial reporting across the enterprise. The assessment of the effectiveness of the company’s internal control over financial reporting is based on criteria established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Because of its inherent limitations, a system of internal control over financial reporting can provide only reasonable assurance and may not prevent or detect misstatements. Management regularly monitors its internal control over financial reporting, and actions are taken to correct deficiencies as they are identified. Based on its assessment, management has concluded that the company’s internal control over financial reporting was effective as of December 31, 2024.
Deloitte & Touche LLP issued an attestation report dated January 29, 2025, concerning the company’s internal control over financial reporting, which is contained in this Annual Report. The company’s consolidated financial statements as of and for the year ended December 31, 2024, have been audited by the independent registered public accounting firm of Deloitte & Touche LLP in accordance with the standards of the Public Company Accounting Oversight Board (United States).

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Directors and Shareholders of
Northrop Grumman Corporation
Falls Church, Virginia
Opinion on Internal Control over Financial Reporting
We have audited the internal control over financial reporting of Northrop Grumman Corporation and subsidiaries (the “Company”) as of December 31, 2024, 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 Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2024, based on the criteria established in Internal Control - Integrated Framework (2013) issued by COSO.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2024 of the Company and our report dated January 29, 2025 expressed an unqualified opinion on those financial statements.
Basis for Opinion
The Company’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 Company’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 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 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.
