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 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 86 percent of our sales in 2023; 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, but not the anticipated profit that would have been earned. 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 Ground Based Strategic Deterrent (“Sentinel”) program is currently under a Nunn-McCurdy breach review.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.A significant shift in government priorities, programs or strategies could have a material adverse effect on our financial position, results of operations and/or cash flows. • Significant delays or reductions in appropriations for our programs and U.S. government funding more broadly, including a prolonged continuing resolution or breach of the debt ceiling, 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-9- NORTHROP GRUMMAN CORPORATIONpredict 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 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 an uncertain and changing political 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 current macroeconomic pressures (especially from inflation and labor and supply chain challenges) are prolonged or worsen, and increased costs continue, then existing or anticipated appropriated and contracted funds may not be sufficient to cover costs incurred on existing or future programs.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.Significant delays or reductions in appropriations for our current and future programs; long-term funding under a continuing resolution; an extended debt ceiling breach or government shutdown; and/or future budget and program decisions, among other items, may negatively impact our business and programs and could have a material adverse effect on our financial position, results of operations and/or cash flows. • We use estimates when accounting for contracts. Contract cost growth or changes in estimated contract revenues and costs can affect our profitability and our overall financial position.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; challenges caused by the global health environment; 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 the government may disagree with our requests and may not have funding to cover them.-10- NORTHROP GRUMMAN CORPORATIONOur 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, and supplier challenges. In 2023, 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. 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. While management uses its best judgment to estimate costs associated with fixed-price contracts, future events could result in significant adjustments. 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 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, or cost-type development work requiring us to provide certain items at our expense or with little or no fee. Ongoing 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 12 to the consolidated financial statements. • The global macroeconomic environment could negatively impact our business and our financial position, results of operations and/or cash flows could be materially adversely affected. Our business, financial position, results of operations and/or cash flows have been and may continue to be adversely impacted by the global macroeconomic environment, which has experienced extraordinary challenges, including high rates of inflation; increased interest rates; widespread disruptions in supply chains; workforce challenges, including labor shortages; and market volatility, including exchange rate volatility. These challenges have, among other things, led to increased costs, labor and supply shortages, and delays and disruption in performance, as well as competing demands for scarce resources. Those challenges have adversely impacted our customers, our industry, our company, our suppliers and others with whom we do business. While some aspects of the macroeconomic environment have improved, and we have been able to mitigate some of the challenges (especially with respect to labor shortages), other challenges persist. We cannot predict the future trajectory or duration of this risk, including how the macroeconomic environment will evolve or how it will continue to impact us. 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. However, if we are unable to do so successfully, our financial position, results of operations and/or cash flows could be materially adversely affected. • Competition within our markets and bid protests may affect our ability to win new contracts and result in reduced revenues and market share. We operate in highly competitive markets and our competitors may have more financial capacity or more extensive or specialized engineering, 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 acquisitions within our industry could further increase competition. We are also facing increasing competition for,-11- NORTHROP GRUMMAN CORPORATIONand 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. Some customers, including the DoD, are turning to commercial contractors, rather than traditional defense contractors, for some products and services, and 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, accurately anticipate our customers’ needs and successfully to effect our digital transformation strategy and adopt and integrate new digital manufacturing and operating technologies into our products and services. Bid protests can result in contract modifications or the award decision being reversed and loss of the contract award. Even where a bid protest does not result in such a loss, it can delay the start of contract activities and earnings. If we are unable to continue to compete successfully against our current or future competitors, or prevail in protests, or to prevail against other attempts to interfere with our ability to obtain and retain awards, we may experience declines in future revenues and market share, which could have a material adverse effect on our financial position, results of operations and/or cash flows.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. 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 have at times been, and may continue to be, increasingly aggressive. We are and 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 allegations 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. An investigation, claim, dispute, enforcement action or litigation, even if pending or not ultimately substantiated 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. Investigations, claims, disputes, enforcement actions, litigation or other legal proceedings could have a material adverse effect on our financial position, results of operations and/or cash flows. See Note 11 to the consolidated financial statements for information regarding investigations, claims and litigation. • The improper conduct of employees, agents, subcontractors, suppliers, business partners or joint ventures in which we participate can impact our reputation, our ability to do business and our financial position, results of operations and/or cash flows. We have implemented policies, training and other compliance controls, and have negotiated contractual terms designed to prevent misconduct by employees, agents or others working with us or on our behalf that would 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. However, we cannot ensure that we will prevent all such misconduct committed by our employees, agents, suppliers, partners or others working with us or on our behalf. We have in the past experienced and may in the future experience such misconduct, despite a vigorous compliance program, our values and strong culture. This risk of improper conduct may increase 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. Notwithstanding our robust processes, we may be unable to prevent misconduct or violations of applicable laws by these joint ventures (including their officers, directors and employees) or our-12- NORTHROP GRUMMAN CORPORATIONpartners. Improper actions by our employees or those with whom or through whom we do business subjects 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, which could negatively impact our reputation and ability to conduct business and could have a material adverse effect on our financial position, results of operations and/or cash flows. • 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 we could be adversely affected by changes in such laws, regulations or terms, or any negative findings by the U.S. government as to our compliance with them. We also may be adversely affected by changes in our customers’ business practices globally. 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 cyber, information 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, and our compliance, and the adequacy of our systems in meeting government requirements. Costs ultimately found to be unallowable or improperly allocated may not be reimbursed or may be refunded. 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 incentive-based fee arrangements; fixed price development or long-term production programs; different award criteria; non-traditional contract provisions; and contract negotiation offers that indicate what our costs should be, 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, may 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. If we or those with whom we do business do not comply with the laws, regulations, rules, contract terms and processes to which we are subject or if customer business practices or requirements change significantly, including with respect to allowable costs, it could affect our ability to compete and have a material adverse effect on our financial position, results of operations and/or cash flows.-13- NORTHROP GRUMMAN CORPORATION• 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 may require us to identify alternate sources, result in additional costs and/or otherwise impact our business and operations. New and evolving laws, regulations and rule makings globally are expected to impose different and more restrictive standards and require greater disclosures. They could also require capital investments, could adversely impact our ongoing operations, and could require changes on a more accelerated time frame. Our suppliers are expected to face similar challenges and incur additional compliance costs that may be passed on to us. These direct and indirect costs may 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. For example, in 2022, the SEC and FAR council issued proposed rule-makings on climate change. The proposed rules, depending on how they are finally adopted, as well as other changes the government might implement, could impose significant new burdens on the company and our suppliers, with significant potential costs and operational impacts, and adversely impact our ability to win business and operate successfully. 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 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, and there can be no assurance the company will achieve its objectives, or meet the evolving sustainability expectations and standards of our investors and other external stakeholders. We may be subject to substantial administrative, civil or criminal fines, penalties or other sanctions (including suspension and debarment) 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. 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. -14- NORTHROP GRUMMAN CORPORATIONGovernment 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.The impact of these factors is difficult to predict, but one or more of them could harm our reputation and business and have a material adverse effect on our financial position, results of operations and/or cash flows. • Unanticipated changes in our tax provisions or exposure to additional tax liabilities could affect our profitability and cash flow. 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 and timing of revenue recognition under IRC Section 451(b), could be materially different from our historical income tax provisions and accruals. 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. 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. Business and Operational Risks • Our business could be negatively impacted by cyber and other security threats or disruptions.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.We have robust measures in place to address and mitigate cyber-related risks. However, we have experienced cyber attacks and expect we will continue to experience additional attacks in the future, including from nation states and non-state actors. We continue to invest in the cybersecurity and resiliency of our networks and products and to enhance our internal controls and processes, which are designed to help protect our systems and infrastructure, and the information they contain. These include timely detection of incidents through monitoring, training, incident response capabilities, and mitigating cyber and security risks to our data, systems, products and services. We also partner with the government and others in our industry to help protect national security. However, given the complex, continuing and evolving nature of cyber and other security threats, including threats from targeting by more advanced and persistent adversaries, including nation states and other actors, these efforts may not be fully effective, particularly against previously unknown vulnerabilities that could go undetected for an extended period. 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 or report cyber incidents in a timely manner, we may suffer financial and other harm, including to our information, operations, performance, employees and reputation. Although we implement various measures and controls to monitor and mitigate risks associated with these threats and to increase the cyber resiliency of our infrastructure and products, there can be no assurance that these processes will be sufficient. Successful attacks could lead to losses or misuse of sensitive information or capabilities; theft or corruption of data; harm to personnel, infrastructure or products; financial costs and liabilities; protracted disruptions in our operations and performance; and the misuse of our products, as well as damage to our reputation as a provider of cyber-related or cyber-protected goods and services. We have not always been able to and may in the future not always be able to obtain adequate insurance to cover our losses. Cyber threats, both on premises and in the cloud, are evolving and include, but are not limited to: malicious software, destructive malware, ransomware, attempts to gain unauthorized access to systems or data, disruption to-15- NORTHROP GRUMMAN CORPORATIONoperations, 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. Some of these threats are zero-day attacks associated with previously unknown vulnerabilities in third party software or products we utilize in our business. Cyber events, if not prevented or effectively mitigated, have caused and could cause harm and require remedial actions. They could also damage our reputation, disrupt performance, impact our ability to obtain future insurance coverage, and lead to loss of business, regulatory actions, liabilities or other financial losses, for which we do not have adequate sources of recovery. We provide systems, products and services to various customers who also face cyber threats. Our systems, products and services 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. Despite rigorous processes, we risk 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. These threats could involve terrorism, insider threats, 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. The occurrence and impact of these various risks are difficult to predict, but one or more of them could have a material adverse effect on our financial position, results of operations and/or cash flows. • Our ability to win new competitions and meet the needs of our customers depends, in part, on our ability to maintain a qualified workforce. Our operating results and growth opportunities are heavily dependent upon our ability to attract and retain sufficient qualified and diverse 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, both with traditional defense companies and commercial companies, globally, and with increasing wage rates. 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. 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 talented and diverse workforce, and to maintain performance levels and our corporate culture. There is also the risk that we are unable to achieve our environmental, social and governance (ESG) goals which may be required by certain of our shareholders, employees, the government and other stakeholders, which could adversely impact our reputation, business and ability to hire and retain talent. 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, the environment appears to be shifting, and if, for example, we 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.-16- NORTHROP GRUMMAN CORPORATIONIf we are unable to attract and retain a qualified workforce, we may be unable to maintain our competitive position or achieve our results, and it could have a material adverse effect on our financial position, results of operations and/or cash flows. • Our earnings and profitability depend, in part, on subcontractor and supplier performance and financial viability as well as raw material and component availability and pricing. 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 behavior, or a misalignment between our contractual obligations to our customers and our agreement 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, in the current macroeconomic environment. 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 and 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, 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, 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 regulatory 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 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 our suppliers are not financially viable, incur increased costs of delays, fail to comply with legal requirements, or otherwise fail to address these risks or meet their obligations to us, it could have a material adverse effect on our financial position, results of operations and/or cash flows. • Our international business exposes us to additional risks, including risks related to geopolitical and economic factors, laws and regulations. Sales to customers outside the U.S. are an important component of our strategy. Our international business (including our participation in joint ventures, 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.-17- NORTHROP GRUMMAN CORPORATIONbusiness 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. Despite robust processes, 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 profitable 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 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. Any of these factors may impact demand for 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. They may include requirements to hire, invest, manufacture or purchase locally, or specific financial obligations, including offset obligations, and they may provide for significant penalties if we fail to meet such requirements. They may also require us to enter into letters of credit, performance bonds, bank guarantees or other financial arrangements. 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 may need to partner successfully with non-U.S. companies, including through joint ventures, teaming agreements, co-production or other arrangements. This risk includes 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. This risk is 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. The occurrence and impact of these factors is difficult to predict, but one or more of them could have a material adverse effect on our financial position, results of operations and/or cash flows. • We face various risks related to health epidemics, pandemics and similar outbreaks, which may have material adverse effects on our business, financial position, results of operations and/or cash flows. We face a wide variety of risks related to health epidemics, pandemics and similar outbreaks, especially of infectious diseases. The global health environment has contributed to business slowdowns or shutdowns, labor shortages, supply chain challenges, changes in government spending and requirements, regulatory challenges, inflationary pressures and market volatility. Although we aim to mitigate impacts of adverse changes in the global health environment, these changes can be unpredictable and we may be unable to effectively mitigate them. If a health-18- NORTHROP GRUMMAN CORPORATIONepidemic, pandemic or similar outbreak were to occur or worsen, we likely would experience broad and varied impacts, including potentially to our workforce and supply chain, with inflationary pressures and increased costs (which may or may not be fully recoverable or insured), schedule and/or production delays, market volatility and other financial impacts. If any or all of these items were to occur, we could experience material adverse impacts on our business, financial position, results of operations and/or cash flows. • 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. 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. It is increasingly necessary to meet evolving customer requirements, to differentiate our offerings, and to achieve efficiencies that we and our suppliers/partners successfully develop digital based solutions and transform our operations. 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 our 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. Certain contracts, primarily involving space satellite systems, contain provisions that entitle the customer to recover fees in the event of failure of the system 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. If we are unable to meet our obligations, including due to issues regarding the design, development or manufacture of our products or services, or we experience launch, platform, satellite system or other failures, it 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. • Our business is subject to disruption caused by natural disasters that could adversely affect our profitability and our overall financial position. 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, and other natural disasters. We expect our facilities, operations, employees and communities in the future, particularly at facilities in coastal areas and areas prone to extreme weather events and water scarcity to continue to be at risk for future natural disasters or-19- NORTHROP GRUMMAN CORPORATIONother 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, and/or poor water quality). If a natural disaster occurs, our operations could be interrupted, our employees could be impacted, we could incur significant costs and our performance could be adversely affected. Our subcontractors and other suppliers have also been, and may in the future be, subject to natural disasters that could cause disruption and affect their ability to deliver or perform. Disruptions also impact the availability and cost of materials needed for manufacturing and could 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 disruption resulting from natural disasters, which may increase, as well as delays in recovery, may be significant. If insurance or other sources are unavailable or insufficient to recover all costs or if we experience a significant disruption to our business due to a natural disaster, it could have a material adverse effect on our financial position, results of operations and/or cash flows. • 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. 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 include products that involve highly explosive or flammable elements. 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 (1) potential liabilities relating to nuclear or non-nuclear launch-related incidents, unintended initiation of energetic materials and explosions, including risk of personal injury, property damage and environmental harm; (2) harmful effects on the environment and human health that may result from nuclear-related activities, operations or incidents; the storage, handling and disposal of radioactive materials; and the development, testing and use of energetics, including in propulsion systems, and unintended explosions or releases and (3) to failed launches. We may be subject to reputational harm and potential liabilities arising out of such incidents or hazardous 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 mitigate some such incidents, as well as potentially insurance coverage and indemnification, but they may not be successful. In addition, our customers may use our products and services in ways that can be unusually hazardous or risky, or in ways that are not intended, which may create potential liabilities for our company, as well as reputational harm. If any of these risks were to materialize (e.g. if there was a nuclear incident, or an incident related to launch activities or the use of energetics or propulsion systems), and if insurance coverage or indemnification or other protection was not fully available, it could adversely affect our reputation and have a material adverse effect on our financial position, results of operations and/or cash flows. • We may be unable fully to exploit or adequately to protect intellectual property rights, which could materially affect our ability to compete, 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 also to access the intellectual property of others under reasonable terms. 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 exploit, protect and access intellectual property. -20- NORTHROP GRUMMAN CORPORATION We own many forms of intellectual property, including U.S. and foreign patents, trademarks, copyrights and trade secrets 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 and including where we do not believe they are entitled to do so. Governments continue to increase efforts to assert or obtain more extensive rights in intellectual property, which could reduce our ability to develop, protect and exploit certain of our intellectual property rights and to compete. Governments also decline at times to make intellectual property of others available to us under acceptable terms. We rely significantly upon proprietary technology, information, processes and know-how. We typically seek to protect this information, including by entering into intellectual property agreements with our employees and other parties such as consultants, teammates and subcontractors. These agreements and other measures may not provide adequate protection for our trade secrets and other proprietary information. In the event of an infringement of such intellectual property rights, a breach of a confidentiality agreement, a misuse or theft of our intellectual property or divulgence of proprietary information, 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 that we are able to negotiate directly with third parties to obtain necessary rights on reasonable terms. That may not be practicable. Our intellectual property is subject to challenge, invalidation, misappropriation 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, could be costly and could divert management’s attention. Moreover, the laws concerning intellectual property rights vary among countries and the protection provided to our intellectual property by foreign laws and courts may not be favorable. If we are unable adequately to exploit our intellectual property rights, to protect our intellectual property rights, to obtain rights to intellectual property of others, it could have a material adverse effect on our reputation, ability to compete for and perform on contracts, financial position, results of operations and/or cash flows.General and Other Risk Factors• Our insurance coverage, customer indemnifications or other liability protections may be unavailable or inadequate to cover all of our significant risks, which could adversely affect our profitability and overall financial position. We endeavor to obtain insurance from financially solid, 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 and property 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 may exit 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. If insurance coverage, customer indemnifications and/or other legal protections are not available or are not sufficient to cover risks or losses, it could have a material adverse effect on our financial position, results of operations and/or cash flows.• 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.-21- NORTHROP GRUMMAN CORPORATION The company’s pension and OPB obligations and related expenses are dependent upon the investment performance of plan assets and various assumptions, including discount 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, resulting in substantial losses and write-downs that would reduce our operating income. Goodwill is an intangible asset that we recognize in connection with acquisitions of third-party businesses. Goodwill accounts for approximately 38 percent of our total assets as of December 31, 2023. Other long-lived assets 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 $500 million of PP&E used 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, which could have a material adverse effect on our financial condition and/or results of operations.

FY 2024-12-31 (later)

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, -8- 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.-9- NORTHROP GRUMMAN CORPORATIONFuture 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-10- NORTHROP GRUMMAN CORPORATIONadditional 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.-11- NORTHROP GRUMMAN CORPORATIONLegal 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-12- NORTHROP GRUMMAN CORPORATIONincentive-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-13- NORTHROP GRUMMAN CORPORATIONled 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 -14- 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.-15- NORTHROP GRUMMAN CORPORATIONOur 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.-16- 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.-17- NORTHROP GRUMMAN CORPORATIONWe 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.-18- NORTHROP GRUMMAN CORPORATIONCertain 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.-19- NORTHROP GRUMMAN CORPORATIONOur 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 -20- 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 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations OVERVIEWThe 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” of our Form 10-K for the year ended December 31, 2022 (“2022 Annual Report on Form 10-K”).Global Security EnvironmentThe 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 global events, including violence and unrest. The same is true for our suppliers and other business partners. The conflict in Ukraine has increased global tensions and instability, highlighted threats and increased global demand, as well as further disrupted global supply chains. We continue to not anticipate significant adverse financial impacts directly from the ongoing conflict. We have experienced, and, while difficult to predict, may continue to experience a modest increase in demand for certain of our goods and services directly and indirectly related to the conflict in Ukraine, either through direct sales or if the U.S. provides increased military assistance and support to Ukraine. More recently, the hostilities in Israel and the Gaza Strip have further heightened global tensions and instability. At this time, it is unknown whether hostilities in this region will escalate into an even larger conflict. The demand for our goods and services may increase, especially if the U.S. provides increased military assistance and support to Israel. We do not have a significant business presence in the region, and therefore do not anticipate significant adverse financial impacts directly from the current conflict. More broadly, the ongoing conflicts in Ukraine and Israel and threats elsewhere, particularly in the Pacific region, have heightened tensions and highlighted security requirements globally, including Europe, the Middle East and the Pacific region, as well as the U.S. These conflicts may result in increased demand for defense products and services from allies and partner nations, particularly in those areas. We are actively exploring both opportunities and risks associated with the broader global security environment. 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 a robust defense capability. We believe our capabilities, particularly in space, C4ISR, missile defense, battle management, advanced weapons, 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 Enviro nment The global economic environment has experienced extraordinary challenges, including high rates of inflation and inflationary pressures; widespread delays and disruptions in supply chains; business slowdowns or shutdowns; workforce challenges and labor shortfalls; and market volatility. Some of these challenges were due, in part, to the global health emergency caused by COVID-19, which the World Health organization declared ended in May 2023. Direct impacts of COVID-19 on our business during 2023 were limited, and we are not currently expecting significant direct impacts on our business going forward. The macroeconomic factors have contributed, and we expect will continue to 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 hard to mitigate challenges caused by the current macroeconomic environment on our business, including by taking steps to support our suppliers and small businesses and enhancing our workforce through extensive hiring, development and retention efforts. However, the broader macroeconomic environment, including inflationary pressures and supply chain challenges, continued adversely to affect the company’s results for the year ended December 31, 2023. We cannot clearly predict how long these macroeconomic challenges will continue, how they will change over time, or what additional resources will be available, but we expect to see this challenging macroeconomic environment continue adversely to impact the global economy, our customers and suppliers, our industry and our company in 2024. -29- NORTHROP GRUMMAN CORPORATION In addition, increased interest rates, raising the cost of borrowing for governments, could further 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 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 EnvironmentThe 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 Israel, threats in the Pacific regions and other security priorities, as well as global inflation, 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, including the U.S. election cycle, may also impact defense budgets and priorities, issues related to the national debt, and 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 2024 have not been enacted. Congress continues to pass short-term continuing resolutions (CR) to fund the federal government. The most recent “laddered” CR passed in January 2024 funds the government through March 2024, depending on the appropriation bill. If Congress does not pass full year appropriations or an additional CR before current funding expires, the federal government (or select departments) could face a shutdown and cease what are characterized as certain non-essential operations. Depending on the nature and duration of a potential shutdown, businesses that rely on government funding, including defense contractors, could be significantly impacted. If the federal government remains under a CR at the end of April 2024, the one percent discretionary spending cuts under the FRA could be triggered, potentially resulting in lower funding on the programs in which we participate. In December 2023, the president signed the National Defense Authorization Act (NDAA) for FY 2024 which supports approximately $886 billion in FY 2024 funding for national defense, $842 billion of which is for the DoD. The political environment, federal budget, debt ceiling and regulatory environment are expected to continue to be the subject of considerable debate, especially in light of the ongoing conflicts and heightened global tensions, the inflationary environment and political tensions. The results of those debates could have material impacts on defense spending broadly and the company’s programs in particular. We anticipate that the broader macroeconomic environment, with ongoing inflationary pressures, pockets of labor challenges, and supply chain disruption, among other considerations, will continue to play a significant role in the outcome of these debates and, in turn, on our industry and company. For further information on the global security and economic environment and U.S. political, budget and regulatory environment, including the risks related thereto, see “Liquidity and Capital Resources,” “Quantitative and Qualitative Disclosures About Market Risks” and “Risks Factors” included in this Form 10-K. Ground-Based Strategic Deterrent (“GBSD” or “Sentinel”) Program Nunn-McCurdy Breach Review Due in part to the impact of macroeconomic factors, in January 2024 the customer provided congressional notification that the Sentinel program is currently under a Nunn-McCurdy breach review, which is required when total program cost estimates exceed certain defined thresholds. This notification, which has been driven primarily by increases in construction and procurement cost projections for the Production and Deployment phases, commences the process to achieve recertification for continuance of the program and update its baseline cost estimates. We are currently executing under a cost-type contract for the Engineering and Manufacturing Development phase, and the Production and Deployment phases are yet to be priced and negotiated. We are continuing to partner with our customer to address this critical mission. For more information, see “Risk Factors”. Disposition of IT and Mission Support Services Business Effective January 30, 2021 (the “Divestiture date”), we completed the sale of our IT and mission support services business (the “IT services divestiture”) for $3.4 billion in cash and recorded a pre-tax gain of $2.0 billion. The IT and mission support services business was comprised of the majority of the former Information Solutions and Services (IS&S) division of Defense Systems (excluding the Vinnell Arabia business); select cyber, intelligence and missions support programs, which were part of the former Cyber and Intelligence Mission Solutions (CIMS) division of Mission Systems; and the former Space Technical Services business unit of Space Systems. Operating results include sales and operating income for the IT and mission support services business prior to the Divestiture -30-NORTHROP GRUMMAN CORPORATIONdate; therefore, no sales and operating income were recognized for this business during the years ended December 31, 2023 and 2022. The company recorded sales of $162 million and pre-tax profit of $20 million for the IT and mission support services business during the year ended December 31, 2021.Operating Performance Assessment and ReportingWe 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. 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). CONSOLIDATED OPERATING RESULTS 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 (expense)/benefit and related tax impacts, which are generally only recognized during the fourth quarter. Transaction-adjusted net earnings and transaction-adjusted earnings per share (transaction-adjusted EPS) exclude the MTM impacts noted above, as well as impacts related to the IT services divestiture, including the gain on sale of the business, associated federal and state income tax expenses, transaction costs, and the make-whole premium for early debt redemption. 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, and with regard to transaction-adjusted net earnings and EPS, the impact of certain divestiture activity. These measures are also consistent with how management views the underlying performance of the business as the impact of MTM accounting and the IT services divestiture are 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.-31- NORTHROP GRUMMAN CORPORATIONSelected financial highlights are presented in the table below: Year Ended December 31 % Change in$ in millions, except per share amounts 2023 2022 2021 2023 2022 Sales $ 39,290 $ 36,602 $ 35,667 7 % 3 % Operating costs and expenses 36,753 33,001 31,996 11 % 3 % Operating costs and expenses as a % of sales 93.5 % 90.2 % 89.7 % Gain on sale of business — — 1,980 — % NM Operating income 2,537 3,601 5,651 (30) % (36) % Operating margin rate 6.5 % 9.8 % 15.8 % Mark-to-market pension and OPB (expense) benefit (422) 1,232 2,355 NM (48) % Federal and foreign income tax expense 290 940 1,933 (69) % (51) % Effective income tax rate 12.4 % 16.1 % 21.6 % Net earnings 2,056 4,896 7,005 (58) % (30) % Diluted earnings per share $ 13.53 $ 31.47 $ 43.54 (57) % (28) %Sales2023 sales increased $2.7 billion, or 7 percent, due to higher sales at all four sectors. 2023 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 16 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 Rate2023 operating income decreased $1.1 billion, or 30 percent, primarily due to a $1.56 billion charge on the B-21 program at Aeronautics Systems, partially offset by higher operating income at Space Systems and Defense Systems. The B-21 charge relates to the low-rate initial production (LRIP) phase of the program and is due principally to a change in our assumptions regarding funding to mitigate the impact of macroeconomic disruptions on the program and higher projected manufacturing costs that reflect recent supplier negotiations and our experience in completing the first aircraft. The decrease was also offset by $311 million of lower unallocated corporate expense, largely due to higher deferred state tax benefits associated with the MTM adjustment and B-21 charge and lower intangible asset amortization and PP&E step-up depreciation, as well as a $118 million reduction in the FAS/CAS operating adjustment. 2023 operating margin rate declined to 6.5 percent from 9.8 percent reflecting the items above. 2023 G&A costs as a percentage of sales decreased to 10.2 percent from 10.6 percent, primarily due to higher sales, which more than offset our continued investments for future business opportunities.For further information regarding product and service operating costs and expenses, see “Product and Service Analysis” below. Mark-to-Market Pension and OPB Benefit/ExpenseThe primary components of pre-tax MTM (expense) benefit are presented in the table below:Year Ended December 31$ in millions 2023 2022 2021 Actuarial (losses) gains on projected benefit obligation $ (1,489) $ 9,662 $ 1,163 Actuarial gains (losses) on plan assets 1,067 (8,430) 1,192 MTM (expense) benefit $ (422) $ 1,232 $ 2,355 -32- NORTHROP GRUMMAN CORPORATION The 2023 MTM expense of $422 million was primarily driven by a 39 basis point decrease in the discount rate from year end 2022, partially offset by actual net plan asset returns of 11.1 percent compared to our 7.5 percent asset return assumption.Federal and Foreign Income TaxesThe 2023 effective tax rate (ETR) decreased to 12.4 percent from 16.1 percent in 2022 primarily due to lower earnings before income taxes as a result of the B-21 charge and MTM expense, which collectively reduced the 2023 ETR by 3.8 percentage points. The 2022 MTM benefit increased the 2022 ETR by 1.2 percentage points. See Note 7 to the consolidated financial statements for additional information.Net EarningsThe table below reconciles net earnings to MTM-adjusted net earnings and transaction-adjusted net earnings:Year Ended December 31 % Change in$ in millions 2023 2022 2021 2023 2022 Net earnings $ 2,056 $ 4,896 $ 7,005 (58) % (30) % MTM expense (benefit) 422 (1,232) (2,355) NM (48) % MTM-related deferred state tax (benefit) expense (1) (22) 65 124 NM (48) % Federal tax (benefit) expense of items above (2) (84) 245 469 NM (48) % MTM adjustment, net of tax 316 (922) (1,762) NM (48) % MTM-adjusted net earnings 2,372 3,974 5,243 (40) % (24) % Gain on sale of business — — (1,980) NM NM State tax impact (3) — — 160 NM NM Transaction costs — — 32 NM NM Make-whole premium — — 54 NM NM Federal tax impact of items above (4) — — 614 NM NM Transaction adjustment, net of tax — — (1,120) NM NM Transaction-adjusted net earnings $ 2,372 $ 3,974 $ 4,123 (40) % (4) %(1) The deferred state tax impact in each period was calculated using the company’s blended state tax rate of 5.25 percent and is included in Unallocated corporate expense within operating income. (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.(3) The state tax impact includes $62 million of incremental tax expense related to $1.2 billion of nondeductible goodwill in the divested business. (4) The federal tax impact was calculated by applying the 21 percent federal statutory rate to the adjustment items and also includes $250 million of incremental tax expense related to $1.2 billion of nondeductible goodwill in the divested business. 2023 net earnings decreased $2.8 billion, or 58 percent, principally due to a $1.7 billion decrease in our MTM (expense) benefit, a $975 million reduction in the non-operating FAS pension benefit and the $1.1 billion decrease in operating income described above, partially offset by a $650 million decrease in income tax expense, a $107 million increase in returns on marketable securities related to our non-qualified benefit plans, and a $97 million gain recognized upon the sale of our minority investment in an Australian business. -33-NORTHROP GRUMMAN CORPORATIONDiluted Earnings Per ShareThe table below reconciles diluted earnings per share to MTM-adjusted EPS and transaction-adjusted EPS:Year Ended December 31 % Change in2023 2022 2021 2023 2022 Diluted earnings per share $ 13.53 $ 31.47 $ 43.54 (57) % (28) % MTM expense (benefit) per share 2.78 (7.92) (14.64) NM (46) % MTM-related deferred state tax (benefit) expense per share (1) (0.14) 0.42 0.77 NM (45) % Federal tax (benefit) expense of items above per share (2) (0.56) 1.57 2.92 NM (46) %MTM adjustment per share, net of tax2.08 (5.93) (10.95) NM (46) %MTM-adjusted EPS15.61 25.54 32.59 (39) % (22) % Gain on sale of business per share — — (12.31) NM NM State tax impact (3) per share — — 0.99 NM NM Transaction costs per share — — 0.20 NM NM Make-whole premium per share — — 0.34 NM NM Federal tax impact of items above (4) per share — — 3.82 NM NM Transaction adjustment per share, net of tax — — (6.96) NM NM Transaction-adjusted EPS $ 15.61 $ 25.54 $ 25.63 (39) % — %(1) The deferred state tax impact in each period was calculated using the company’s blended state tax rate of 5.25 percent and is included in Unallocated corporate expense within operating income.

For a more complete description of each segment’s products and services, see “Business.”Segment Operating Income and Margin RateSegment 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).

Operating income at Space Systems and Defense Systems was higher than in the prior year period.FAS/CAS Operating AdjustmentThe decrease in our 2023 FAS/CAS operating adjustment is primarily due to lower FAS pension service expense resulting from changes in certain actuarial assumptions as of December 31, 2022. Unallocated Corporate Expense (Income) The decrease in 2023 unallocated corporate expense is primarily due to higher deferred state tax benefits associated with the MTM adjustment and B-21 charge and lower intangible asset amortization and PP&E step-up depreciation.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.

The increase was principally driven by higher restricted sales at Space Systems and Aeronautics Systems, higher volume on restricted programs and F-35 sustainment at Mission Systems, and higher volume on an international training program at Defense Systems. -38-NORTHROP GRUMMAN CORPORATION2023 service costs increased $180 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, 2023 and 2022: 2023 2022 $ in millions Funded Unfunded Total Backlog Total Backlog % Change in 2023 Aeronautics Systems $ 9,660 $ 9,923 $ 19,583 $ 19,397 1 % Defense Systems 6,346 1,718 8,064 7,515 7 % Mission Systems 11,334 4,774 16,108 13,875 16 % Space Systems 10,035 30,440 40,475 37,956 7 % Total backlog $ 37,375 $ 46,855 $ 84,230 $ 78,743 7 % 2023 net awards totaled $44.8 billion. Significant 2023 new awards include $15.5 billion for restricted programs (primarily at Space Systems, Aeronautics Systems and Mission Systems), $2.1 billion for F-35 programs (primarily at Aeronautics Systems and Mission Systems), $1.7 billion for E-2, $1.5 billion for Triton, $1.4 billion for SDA Tranche 2 Transport Layer, and $0.8 billion for GMLRS. Subsequent Event – In January 2024, the company received a termination for convenience in our restricted Space business. The company expects to reduce backlog by approximately $2 billion during the first quarter of 2024 related to the termination.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, 2023, we had cash and cash equivalents of $3.1 billion; $277 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 2023, we renewed our one-year $500 million uncommitted credit facility. At December 31, 2023, there were no borrowings outstanding under these credit facilities. In February 2023, we issued $2.0 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, 2023, we had $20.7 billion of purchase obligations, approximately half of which is short-term. Purchase obligations are largely comprised of open purchase 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, 2023, we had capital expenditure commitments of $1.4 billion, which we expect to satisfy with cash on hand. We also had provisions for uncertain tax positions of $2.0 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 3), commercial paper, credit facilities and long-term debt (Note 10), standby letters of -39-NORTHROP GRUMMAN CORPORATIONcredit and guarantees (Note 12), future minimum contributions for the company’s pension and OPB plans (Note 13), and lease payment obligations (Note 15). Internal Revenue Code (IRC) Section 174 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 2022 cash from operations were reduced by approximately $900 million for federal estimated tax payments we made related to Section 174. As we finalized our 2022 federal tax return along with our continued analysis of research and development expenditures, we reduced the previously estimated impact of Section 174 on our tax liability for 2022 and 2023 to approximately $700 million and $500 million, respectively. Congress is considering legislation that would defer the amortization requirement to later years, possibly with retroactive effect. In the meantime, we expect to continue to make additional federal tax payments based on the current Section 174 tax law. The impact of Section 174 on our cash from operations depends on the amount of research and development expenditures incurred by the company and whether the IRS issues guidance on the provision which differs from our current interpretation, among other things.Cash Flow Measures In addition to our cash position, we consider various cash flow measures in capital deployment decision-making, including cash provided by operating activities and adjusted free cash flow, a non-GAAP measure described in more detail below. Operating Cash Flow The table below summarizes key components of cash provided by operating activities: Year Ended December 31$ in millions 2023 2022 2021 Net earnings $ 2,056 $ 4,896 $ 7,005 Gain on sale of business — — (1,980) B-21 charge 1,559 — —Non-cash items (1)551 (1,305) (1,510) Pension and OPB contributions (139) (136) (141) Changes in trade working capital (144) (600) 181 Other, net (8) 46 12 Net cash provided by operating activities $ 3,875 $ 2,901 $ 3,567 (1) Includes depreciation and amortization, non-cash lease expense, MTM (expense) benefit, stock based compensation expense, deferred income taxes and net periodic pension and OPB income. 2023 cash provided by operating activities increased $974 million, or 34 percent, principally due to improved trade working capital largely driven by increased billings and cash collections, partially offset by higher supplier payments.Adjusted Free Cash FlowAdjusted free cash flow, as reconciled in the table below, is a non-GAAP measure defined as net cash provided by or used in operating activities, less capital expenditures, plus proceeds from the sale of equipment to a customer (not otherwise included in net cash provided by or used in operating activities) and the after-tax impact of discretionary pension contributions, if any. Adjusted free cash flow includes proceeds from the sale of equipment to a customer as such proceeds were generated in a customer sales transaction. It also includes the after-tax impact of discretionary pension contributions for consistency and comparability of financial performance. This measure may not be defined and calculated by other companies in the same manner. We use adjusted free cash flow as a key factor in our planning for, and consideration of, acquisitions, the payment of dividends and stock repurchases. This non-GAAP measure may be useful to investors and other users of our financial statements as a supplemental measure of our cash performance, but should not be considered in isolation, as a measure of residual cash flow available for discretionary purposes, or as an alternative to operating cash flows presented in accordance with GAAP. -40-NORTHROP GRUMMAN CORPORATIONThe table below reconciles net cash provided by operating activities to adjusted free cash flow: Year Ended December 31 % Change in$ in millions 2023 2022 2021 2023 2022 Net cash provided by operating activities $ 3,875 $ 2,901 $ 3,567 34 % (19) % Capital expenditures (1,775) (1,435) (1,415) 24 % 1 % Proceeds from sale of equipment to a customer — 155 84 (100) % 85 % Adjusted free cash flow $ 2,100 $ 1,621 $ 2,236 30 % (28) % 2023 adjusted free cash flow increased $479 million, or 30 percent, principally due to higher net cash provided by operating activities, partially offset by an increase in capital expenditures.Investing Cash Flow2023 net cash used in investing activities increased $341 million principally due to higher capital expenditures. Proceeds from the sale of minority investments in 2023 were largely offset by cash received in 2022 from the sale of equipment to a customer.Financing Cash Flow2023 net cash used in financing activities decreased $852 million principally due to the issuance of $2.0 billion in long-term debt, partially offset by $1.05 billion in debt repayments. Cash returned to shareholders through share repurchases and dividends totaled $2.6 billion in each period.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.We also consider the impact of macroeconomic factors on our estimates, in particular on contract EACs that span several years. For example, during 2023, we included in our EACs management’s best estimate of the impact inflation has had and may continue to have on our contracts. We also included our current best estimate of the impact on our EACs of disruptions we have experienced and continue to experience in the supply chain. The volatility of the recent macroeconomic environment has added complexity to our estimation process and may result in our year end 2023 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. -41-NORTHROP GRUMMAN CORPORATIONWe 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 BenefitsOverview – 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 annual 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 5.15 percent at December 31, 2023 and 5.54 percent at December 31, 2022. 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, 2023 discount rate assumption would have the following estimated effects on 2023 pension and OPB obligations, which would be reflected in the 2023 MTM expense (benefit), and 2024 expected pension and OPB expense: $ in millions 25 Basis Point Decrease in Rate 25 Basis Point Increase in Rate 2023 pension and OPB obligation and MTM expense (benefit) $ 866 $ (827) 2024 pension and OPB (benefit) expense (23) 22 -42-NORTHROP GRUMMAN CORPORATIONCash 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 used for FAS purposes 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 4.02 percent for all years. Holding all other assumptions constant, an increase or decrease of 25 basis points in the December 31, 2023 cash balance crediting rate assumption would have the following estimated effects on the 2023 pension benefit obligation, which would be reflected in the 2023 MTM expense (benefit), and 2024 expected pension expense:$ in millions 25 Basis Point Decrease in Rate 25 Basis Point Increase in Rate2023 pension obligation and MTM expense (benefit) $ (105) $ 108 2024 pension (benefit) expense(9) 9Expected 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 2023, 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 40% to 43%. The current asset allocation is now approximately 42% fixed-income, 27% public equities, 28% alternatives and 3% 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 13 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 2023 was approximately 10.7 percent and our 20-year and 30-year rolling average rates of return were approximately 7.9 percent and 8.7 percent, respectively, each determined on an arithmetic basis and net of expenses. Our 2023 return on plan assets, net of expenses, were approximately 11.1 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 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 2023 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 7.23 percent. For 2024 FAS expense, we have assumed an expected long-term rate of return on pension plan assets of 7.5 percent and 7.12 percent on OPB plans. Holding all other assumptions constant, an increase or decrease of 25 basis points in our December 31, 2023 EROA assumption would have the following estimated effects on 2024 expected pension and OPB expense: $ in millions 25 Basis Point Decrease 25 Basis Point Increase 2024 pension and OPB expense (benefit) $ 76 $ (76) -43-NORTHROP GRUMMAN CORPORATIONIn 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 2024 MTM expense (benefit):$ in millions 100 Basis Point Decrease 100 Basis Point Increase2024 MTM expense (benefit) $ 305 $ (305) 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 – Mortality assumptions are used 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 did not release a MP-2022 or MP-2023 projection scale citing complexities in incorporating the substantial number of “excess deaths” in 2020 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, 2023, and the amounts estimated for our 2024 pension and OPB expense. For further information regarding our pension and OPB plans, see “Risk Factors” and Notes 1 and 13 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 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 be able to recover a 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, 2023, we expect approximately 90 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 -44-NORTHROP GRUMMAN CORPORATIONremediation 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, 2023, we have approximately $2.0 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 7, Note 11 and Note 12 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 $500 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, 2023 and 2022, 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, 2023, 2022 and 2021. 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 2023, 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 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 -45-NORTHROP GRUMMAN CORPORATIONoperating 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, 2023, 2022 and 2021.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.-46-NORTHROP GRUMMAN CORPORATION

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations OVERVIEWThe 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 EnvironmentThe 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 EnvironmentThe 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 -28-NORTHROP GRUMMAN CORPORATIONgovernment 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 ReportingWe 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. -29- 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). CONSOLIDATED OPERATING RESULTS 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: Year Ended December 31 % Change in$ in millions, except per share amounts 2024 2023 2022 2024 2023 Sales $ 41,033 $ 39,290 $ 36,602 4 % 7 % Operating costs and expenses 36,663 36,753 33,001 — % 11 % Operating costs and expenses as a % of sales 89.4 % 93.5 % 90.2 % Operating income 4,370 2,537 3,601 72 % (30) % Operating margin rate 10.6 % 6.5 % 9.8 % Mark-to-market pension and OPB benefit (expense) 443 (422) 1,232 NM NM Federal and foreign income tax expense 842 290 940 190 % (69) % Effective income tax rate 16.8 % 12.4 % 16.1 % Net earnings 4,174 2,056 4,896 103 % (58) % Diluted earnings per share $ 28.34 $ 13.53 $ 31.47 109 % (57) %Sales2024 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. -30- NORTHROP GRUMMAN CORPORATION 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 Rate2024 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 $25 million of lower intangible amortization and PP&E step-up depreciation. 2024 operating margin rate increased to 10.6 percent from 6.5 percent reflecting the items above. 2024 G&A costs as a percentage of sales decreased to 9.7 percent from 10.2 percent primarily due to higher sales.For further information regarding product and service operating costs and expenses, see “Product and Service Analysis” below. Mark-to-Market Pension and OPB Benefit/ExpenseThe primary components of pre-tax MTM benefit (expense) are presented in the table below:Year Ended December 31$ 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 $443 million was primarily driven by a 58 basis point increase in the discount rate from year end 2023, partially offset by actual net plan asset returns of 4.7 percent compared to our 7.5 percent asset return assumption.Federal and Foreign Income TaxesThe 2024 effective tax rate (ETR) increased to 16.8 percent from 12.4 percent in 2023 primarily due to the impact of the prior year B-21 charge and the MTM adjustment on our ETR. The 2024 MTM benefit increased the 2024 ETR by 0.4 percentage points, whereas the prior year B-21 charge and MTM expense collectively reduced the 2023 ETR by 3.8 percentage points. The 2024 ETR also reflects a net reduction in tax reserves largely due to a recent federal court decision, partially offset by higher interest expense on unrecognized tax benefits. See Note 6 to the consolidated financial statements for additional information.Net EarningsThe table below reconciles net earnings to MTM-adjusted net earnings:Year Ended December 31 % Change in$ in millions 2024 2023 2022 2024 2023 Net earnings $ 4,174 $ 2,056 $ 4,896 103 % (58) % MTM (benefit) expense (443) 422 (1,232) NM NM MTM-related deferred state tax expense (benefit) (1) 23 (22) 65 NM NM Federal tax expense (benefit) of items above (2) 88 (84) 245 NM NM MTM adjustment, net of tax (332) 316 (922) NM NM MTM-adjusted net earnings $ 3,842 $ 2,372 $ 3,974 62 % (40) %(1) The deferred state tax impact in each period was calculated using the company’s blended state tax rate of 5.25 percent and is included in Unallocated corporate expense within operating income. (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 -31-NORTHROP GRUMMAN CORPORATIONrecognized in the prior year upon the sale of our minority investment in an Australian business, and $76 million of higher interest expense on our long-term debt.Diluted Earnings Per ShareThe table below reconciles diluted earnings per share to MTM-adjusted EPS:Year Ended December 31 % Change in2024 2023 2022 2024 2023 Diluted earnings per share $ 28.34 $ 13.53 $ 31.47 109 % (57) % MTM (benefit) expense per share (3.02) 2.78 (7.92) NM NM MTM-related deferred state tax expense (benefit) per share (1) 0.16 (0.14) 0.42 NM NM Federal tax expense (benefit) of items above per share (2) 0.60 (0.56) 1.57 NM NMMTM adjustment per share, net of tax(2.26) 2.08 (5.93) NM NMMTM-adjusted EPS$ 26.08 $ 15.61 $ 25.54 67 % (39) %(1) The deferred state tax impact in each period was calculated using the company’s blended state tax rate of 5.25 percent and is included in Unallocated corporate expense within operating income.

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 RateSegment 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. -32-NORTHROP GRUMMAN CORPORATIONYear Ended December 31 % Change in$ in millions 2024 2023 2022 2024 2023 Operating income $ 4,370 $ 2,537 $ 3,601 72 % (30) % Operating margin rate 10.6 % 6.5 % 9.8 %Reconciliation to segment operating income:CAS pension expense (279) (154) (167) 81 % (8) % FAS pension service expense 239 236 367 1 % (36) % FAS/CAS operating adjustment (40) 82 200 NM (59) % Intangible asset amortization and PP&E step-up depreciation 97 122 242 (20) % (50) % Deferred state tax expense (benefit) (1) of MTM adjustment 23 (22) 65 NM (134) %Deferred state tax benefit of B-21 charge (1)— (82) — NM NM Other unallocated corporate expense 94 123 145 (24) % (15) % Unallocated corporate expense 214 141 452 52 % (69) % Segment operating income $ 4,544 $ 2,760 $ 4,253 65 % (35) % Segment operating margin rate 11.1 % 7.0 % 11.6 % (1) Represents the deferred state tax expense (benefit) associated with MTM benefit (expense) and the prior year B-21 charge, which are recorded in Unallocated corporate expense consistent with other changes in deferred state taxes.Segment Operating Income and Margin Rate2024 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 AdjustmentThe 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 $127 million increase in deferred state taxes associated with the prior year B-21 charge and the MTM adjustment, partially offset by lower intangible asset amortization and PP&E step-up depreciation and a loss recognized in the prior year in connection with the divestiture of a small international subsidiary.Net Estimate-At-Completion (EAC) Adjustments - We record changes in estimated contract earnings at completion (net EAC adjustments) using the cumulative catch-up method of accounting. Net EAC adjustments can have a significant effect on reported sales and operating income and the aggregate amounts are presented in the table below: Year Ended December 31$ in millions 2024 2023 2022 Favorable EAC adjustments $ 1,461 $ 1,314 $ 1,337 Unfavorable EAC adjustments (1,111) (1,230) (977) Net EAC adjustments $ 350 $ 84 $ 360 -33-NORTHROP GRUMMAN CORPORATION Net EAC adjustments by segment are presented in the table below: Year Ended December 31$ in millions 2024 2023 2022 Aeronautics Systems $ 151 $ (44) $ 174 Defense Systems 96 91 104 Mission Systems 59 149 138 Space Systems 42 (101) (31) Eliminations 2 (11) (25) Net EAC adjustments $ 350 $ 84 $ 360AERONAUTICS SYSTEMSAeronautics Systems is a leader in the design, development, production, integration, sustainment and modernization of military aircraft systems for the U.S. Air Force, the U.S. Navy, other U.S. government agencies, and international customers.

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 Income2024 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.MISSION SYSTEMSMission Systems is a leader in advanced mission solutions and multifunction systems, primarily for the U.S. defense and intelligence community, and international customers.

These increases were partially offset by lower sales on restricted airborne radar programs and the Scalable Agile Beam Radar (SABR) program.Operating Income2024 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. -35- NORTHROP GRUMMAN CORPORATIONSPACE SYSTEMSSpace Systems is a leader in delivering end-to-end mission solutions through the design, development, integration, production and operation of space, missile defense, and launch systems for national security, civil government, commercial and international customers.

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 Income2024 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 $42 million benefit from insurance recoveries in our commercial space business during 2023. -36- NORTHROP GRUMMAN CORPORATIONPRODUCT AND SERVICE ANALYSIS The following table presents product and service sales and operating costs and expenses by segment: Year Ended December 31$ in millions 2024 2023 2022Segment Information: Sales Operating Costs and Expenses Sales Operating Costs and Expenses Sales Operating Costs and Expenses Aeronautics SystemsProduct $ 9,064 $ 8,248 $ 8,157 $ 8,942 $ 7,981 $ 7,161 Service 2,723 2,382 2,389 2,099 2,311 2,042 Intersegment eliminations 243 218 240 218 239 212 Total Aeronautics Systems 12,030 10,848 10,786 11,259 10,531 9,415Defense SystemsProduct 5,843 5,304 5,282 4,819 4,604 4,163 Service 1,862 1,641 2,231 1,959 2,231 1,985 Intersegment eliminations 855 749 776 682 794 700 Total Defense Systems 8,560 7,694 8,289 7,460 7,629 6,848Mission SystemsProduct 8,076 7,000 7,749 6,669 7,376 6,291 Service 2,146 1,805 2,092 1,730 2,005 1,639 Intersegment eliminations 1,177 996 1,054 887 1,015 848 Total Mission Systems 11,399 9,801 10,895 9,286 10,396 8,778Space SystemsProduct 9,743 8,711 9,709 8,844 8,561 7,664 Service 1,576 1,398 1,681 1,468 1,533 1,404 Intersegment eliminations 412 368 483 431 476 424 Total Space Systems 11,731 10,477 11,873 10,743 10,570 9,492 Total Product $ 32,726 $ 29,263 $ 30,897 $ 29,274 $ 28,522 $ 25,279 Total Service 8,307 7,226 8,393 7,256 8,080 7,070 Total Segment (1) $ 41,033 $ 36,489 $ 39,290 $ 36,530 $ 36,602 $ 32,349 (1) A reconciliation of segment operating income to total operating income is included in “Segment Operating Results.”Product Sales and Costs2024 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, F-35, 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.-37-NORTHROP GRUMMAN CORPORATIONService 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 F-35 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 $ in millions Funded Unfunded Total Backlog Total Backlog % Change in 2024 Aeronautics Systems $ 10,689 $ 13,409 $ 24,098 $ 19,583 23 % Defense Systems 9,873 17,845 27,718 20,198 37 % Mission Systems 11,574 4,869 16,443 16,108 2 % Space Systems 7,526 15,683 23,209 28,341 (18) % 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 F-35 (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 -38-NORTHROP GRUMMAN CORPORATIONorder 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 $513 million, or 13 percent, principally due to improved trade working capital, largely driven by lower net tax payments, as well as higher net earnings.Adjusted Free Cash FlowAdjusted free cash flow, as reconciled in the table below, is a non-GAAP measure defined as net cash provided by or used in operating activities, less capital expenditures, plus proceeds from the sale of equipment to a customer (not otherwise included in net cash provided by or used in operating activities) and the after-tax impact of discretionary pension contributions, if any. Adjusted free cash flow includes proceeds from the sale of equipment to a customer as -39-NORTHROP GRUMMAN CORPORATIONsuch proceeds were generated in a customer sales transaction. It also includes the after-tax impact of discretionary pension contributions for consistency and comparability of financial performance. This measure may not be defined and calculated by other companies in the same manner. We use adjusted free cash flow as a key factor in our planning for, and consideration of, acquisitions, the payment of dividends and stock repurchases. This non-GAAP measure may be useful to investors and other users of our financial statements as a supplemental measure of our cash performance, but should not be considered in isolation, as a measure of residual cash flow available for discretionary purposes, or as an alternative to operating cash flows presented in accordance with GAAP.The table below reconciles net cash provided by operating activities to adjusted free cash flow: Year Ended December 31 % Change in$ 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 Flow2024 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 Flow2024 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.-40-NORTHROP GRUMMAN CORPORATIONWe 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 BenefitsOverview – 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. -41-NORTHROP GRUMMAN CORPORATIONThe 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 Rate2024 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) 9Expected 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 -42-NORTHROP GRUMMAN CORPORATIONconsidered 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 Increase2025 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 -43-NORTHROP GRUMMAN CORPORATIONthan 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 -44-NORTHROP GRUMMAN CORPORATIONspending 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.-45-NORTHROP GRUMMAN CORPORATION
