This group closely follows the recommendations of the World Health Organization and the U.S. Centers for Disease Control and Prevention, as well as national and local authorities in the regions where we perform work for our customers.

We believe we are a leader in the field of occupational health and safety (“OH&S”), and we place a strong emphasis on these activities, both internally and on behalf of our customers. Internally, we emphasize direct management responsibility, corporate policies and procedures, OH&S program implementation, employee training and compliance assessments. Our corporate policies and procedures support compliance with OH&S regulations at work locations. We have a proactive compliance program of employee education, training, auditing and reporting that, through employee awareness and integration into our business operations, supports our commitment to a safe and healthy work environment.

Environmental Matters

Our operations are subject to various foreign, federal, state and local environmental protection and health and safety laws and regulations. In addition, our operations may become subject to future laws and regulations, including those related to climate change and environmental sustainability. See "Risk Factors" in this Annual Report on Form 10-K for further details. Although we do not currently anticipate that the costs of complying with, or the liabilities associated with, environmental laws will materially and adversely affect us, we cannot ensure that we will not incur material costs or liabilities in the future.

Research and Development

We conduct research and development activities under customer-funded contracts and with company-funded research and development funds. Company-funded research and development includes independent research and development ("IR&D") and commercial and international research and development. Company-funded research and development expenses are included in selling, general and administrative expenses. Our company-funded research and development expense was $116 million, $109 million and $73 million for fiscal 2022, 2021 and 2020, respectively, which as a percentage of consolidated revenues was 0.8% for both fiscal 2022 and 2021 and 0.6% for fiscal 2020. We charge expenses for research and development activities performed under customer contracts directly to cost of revenues for those contracts.

Intellectual Property Rights

Our technical services and products are not generally dependent upon patent protection, although we do selectively seek patent protection. We claim a proprietary interest in certain of our products, software programs, methodologies and know-how. This proprietary information is protected in confidence as trade secrets, using non-disclosure and other definitive agreements. We selectively pursue opportunities to license or transfer our technologies to third parties.

In connection with the performance of services and solutions, the U.S. government has certain rights to inventions, data, software codes and related material that we develop under U.S. government-funded contracts and subcontracts. Generally, the U.S. government may disclose or license such information to third parties, including, in some instances, our competitors. In the case of some subcontracts that we perform, the prime contractor generally obtains rights to use the programs and products that we deliver under the subcontract to perform its prime contract obligations.

Competition

Competition for contracts is significant, and we often compete against a large number of well-established corporations that may have greater name and brand recognition. We also compete against smaller, more specialized companies that concentrate their resources on particular areas, the U.S. government’s own capabilities and federal non-profit contract research centers. As a result of the diverse requirements of the U.S. government and our commercial customers, we frequently collaborate with other companies to compete for large contracts and bid against these same companies in other situations.

We believe that our principal competitors currently include the following companies: Amentum Services Inc., Booz Allen Hamilton Inc., CACI International Inc., General Dynamics Corporation, Jacobs Engineering Group Inc., KBR Inc., L3Harris, Lockheed Martin Corporation, Northrop Grumman Corporation, Raytheon Technologies Corporation, SAIC and Peraton. These companies span across sectors that include engineering and technical services divisions of large defense contractors, diversified U.S. and international IT providers and contractors focused solely on technical services, supply chain management, other logistics services and major systems operations and maintenance, homeland security and health solutions.

We compete on various factors, including our technical expertise and qualified professional and/or security-cleared personnel, our ability to deliver innovative cost-effective solutions in a timely manner, successful program execution, our reputation and standing with customers, pricing, the size and geographic presence of our company and past performance credentials.

Contract Procurement

Our business is heavily regulated, and we must comply with and are affected by laws and regulations relating to the formation, administration and performance of U.S. government and other contracts. The U.S. government procurement environment has evolved due to statutory and regulatory procurement reform initiatives. Today, U.S. government customers employ several contracting methods to purchase services and products. Budgetary pressures and reforms in the procurement process have caused many U.S. government customers to increasingly purchase services and products using contracting methods that give them the ability to select multiple contract winners or pre-qualify certain contractors to provide services or products on established general terms and conditions rather than through single-award contracts. The predominant contracting methods through which U.S. government agencies procure services and products include the following:

• Definitive Award Contracts. U.S. government agencies may procure services and products through single definitive award contracts which specify the scope of services or products purchased and identify the contractor that will provide the specified services or products. When an agency has a requirement, the agency will issue a solicitation or request for proposal to which interested contractors can submit a proposal. The bidding and selection process can take a year or more to complete. For the contractor, this method of contracting may provide greater certainty of the timing and amounts to be received at the time of contract award because it generally results in the customer contracting for a specific scope of services or products from the single definitive successful awardee.

• Indefinite Delivery/Indefinite Quantity ("IDIQ") Contracts. The U.S. government uses IDIQ contracts to obtain commitments from contractors to provide certain services or products on pre-established terms and conditions. The U.S. government then issues task orders under the IDIQ contracts to purchase the specific services or products it needs. IDIQ contracts are awarded to one or more contractors following a competitive procurement process. Under a single-award IDIQ contract, all task orders under that contract are awarded to one pre-established contractor. Under a multiple-award IDIQ contract, task orders can be awarded to any of the pre-established contractors, which can result in further limited competition for the award of task orders. Multiple-award IDIQ contracts that are open for any government agency to use for procurement are commonly referred to as "government-wide acquisition contracts." IDIQ contracts often have multi-year terms and unfunded ceiling amounts, therefore enabling, but not committing, the U.S. government to purchase substantial amounts of services or products from one or more contractors. At the time an IDIQ contract is awarded (prior to the award of any task orders), a contractor may have limited or no visibility as to the ultimate amount of services or products that the U.S. government will purchase under the contract, and in the case of a multiple-award IDIQ, the contractor from which such purchases may be made.

Table of Contents

PART I

• U.S. General Services Administration ("GSA") Schedule Contracts. The GSA maintains listings of approved suppliers of services and products with agreed-upon prices for use throughout the U.S. government. In order for a company to provide services under a GSA Schedule contract, a company must be pre-qualified and awarded a contract by the GSA. When an agency uses a GSA Schedule contract to meet its requirements, the agency, or the GSA on behalf of the agency, conducts the procurement. The user agency, or the GSA on its behalf, evaluates the user agency’s requirements and initiates a competition limited to GSA Schedule qualified contractors. GSA Schedule contracts are designed to provide the user agency with reduced procurement time and lower procurement costs. Similar to IDIQ contracts, at the time a GSA Schedule contract is awarded, a contractor may have limited or no visibility as to the ultimate amount of services or products that the U.S. government will purchase under the contract.

• Other Transaction Authority (“OTA”) agreements. Under certain circumstances, U.S. government agencies can enter into OTA agreements instead of traditional contracts. These agreements are used for two primary purposes: (1) to carry out basic, applied or advanced research projects that typically relate to technology stimulation or research, and (2) to carry out prototype projects that are directly relevant to enhancing the mission effectiveness of military personnel and the supporting platforms, systems, components or materials proposed to be acquired or developed by the DoD, or to improve platforms, systems, components or materials in use by DoD components and agencies. OTA agreements are generally exempt from federal procurement regulations. These exemptions grant the U.S. government the flexibility to include, amend or exclude contract clauses and requirements that are mandatory in traditional procurements. OTA agreements also grant more flexibility to structure agreements in numerous ways, including joint ventures, partnerships or multiple agencies joining together to fund an agreement encompassing multiple providers.

We often partner with other companies, including our competitors, to submit bids for large U.S. government procurements or other opportunities where we believe that the combination of services and products that we can provide as a team will help us win and perform the contract. Our relationships with our partners, including whether we serve as the prime contractor or as a subcontractor, vary with each contract opportunity and typically depend on the program, contract or customer requirements, as well as the relative size, qualifications, capabilities, customer relationships and experience of our company and our partners.

Contracting with the U.S. government also subjects us to substantial regulation and unique risks, including the U.S. government’s ability to cancel any contract at any time through a termination for the convenience of the U.S. government. Most of our contracts have cancellation terms that would permit us to recover all or a portion of our incurred costs and fees for work performed where the U.S. government issues a termination for convenience. These regulations and risks are described in more detail below under "Business–Regulation" and "Risk Factors" in this Annual Report on Form 10-K.

Contract Types

Generally, the type of contract for our services and products is determined by or negotiated with the U.S. government and may depend on certain factors, including the type and complexity of the work to be performed, degree and timing of the responsibility to be assumed by the contractor for the costs of performance, the extent of price competition and the amount and nature of the profit incentive offered to the contractor for achieving or exceeding specified standards or goals. We generate revenues under several types of contracts, including the following:

• Cost-reimbursement contracts include cost-plus-fixed-fee, award-fee and incentive-fee contracts. These contracts provide for reimbursement of our direct contract costs and allocable indirect costs, plus a fee. These contracts are typically used when uncertainties involved in contract performance do not permit costs to be estimated with sufficient accuracy to use a fixed-price contract. Cost-reimbursement contracts generally subject us to lower risk but require us to use our best efforts to accomplish the scope of the work within a specified time and budget. Award and incentive fees are generally based on performance criteria such as cost, schedule, quality and/or technical performance. Award fees are determined and earned based on customer evaluation of the company's performance against contractual criteria. Incentive fees that are based on cost provide for an initially negotiated fee to be adjusted later, typically using a formula to measure performance against the associated criteria, based on the relationship of total allowable costs to total target costs.

Leidos Holdings, Inc. Annual Report - 12

Table of Contents

PART I

• Fixed-price-incentive-fee ("FP-IF") contracts are substantially similar to cost-plus-incentive-fee contracts except they require specified targets for cost and profit, price ceiling (but not a profit ceiling or floor) and profit adjustment formula. Under an FP-IF contract, the allowable costs incurred are eligible for reimbursement but are subject to a cost-share arrangement, which affects profitability. Generally, if our costs exceed the contract target cost or are not allowable under the applicable regulations, we may not be able to obtain reimbursement for all costs and may have our fees reduced or eliminated.

• Time-and-materials ("T&M") contracts typically provide for negotiated fixed hourly rates for specified categories of direct labor plus reimbursement of other direct costs. This type of contract is generally used when there is uncertainty about the extent or duration of the work to be performed by the contractor at the time of contract award or it is not possible to anticipate costs with any reasonable degree of confidence. On T&M contracts, we assume the risk of providing appropriately qualified staff to perform these contracts at the hourly rates set forth in the contracts over the period of performance of the contracts.

• Fixed-price-level-of-effort ("FP-LOE") contracts are substantially similar to T&M contracts except they require a specified level of effort over a stated period of time on work that can be stated only in general terms. This type of contract is generally used when the contractor is required to perform an investigation or study in a specific research and development area and to provide a report showing the results achieved based on the level of effort. Payment is based on the effort expended rather than the results achieved.

• Firm-Fixed-Price (“FFP”) contracts provide for a fixed price for specified products, systems and/or services. This type of contract is typically used when the customer acquires products and services on the basis of reasonably definitive specifications that have a determinable fair and reasonable price. These contracts offer us potential increased profits if we can complete the work at lower costs than planned, but FFP contracts increase our exposure to the risk of cost overruns.

Our earnings and profitability may vary materially depending on changes in the proportionate amount of revenues derived from each type of contract and the nature of services or products provided, as well as the achievement of performance objectives and the stage of performance at which the right to receive fees, particularly under incentive-fee and award-fee contracts, is finally determined. Cost-reimbursement and T&M contracts generally have lower profitability than FFP contracts.

Seasonality

The U.S. government's fiscal year ends on September 30 of each year. While not certain, it is not uncommon for U.S. government agencies to award extra tasks or complete other contract actions in the timeframe leading up to the end of its fiscal year in order to avoid the loss of unexpended fiscal year funds, which may favorably impact our third fiscal quarter. In addition, our quarterly results may be impacted by the number of working days in a given quarter. We tend to generate less revenue from our labor services during the fourth quarter as a result of the holiday season.

Regulation

We are heavily regulated in most of the fields in which we operate. We provide services and products to numerous U.S. government agencies and entities, including to the DoD, the U.S. Intelligence Community and the DHS. When working with these and other U.S. government agencies and entities, we must comply with various laws and regulations relating to the formation, administration and performance of contracts. Some significant laws and regulations that affect us include:

• the Federal Acquisition Regulation ("FAR") and supplements, including the DoD Federal Acquisition Regulation Supplement ("DFARS"), which regulate the formation, administration and performance of U.S. government contracts;

• the Truth in Negotiations Act, which requires certification and disclosure of cost and pricing data in connection with certain contract negotiations;

• the Procurement Integrity Act, which regulates access to competitor bid and proposal information and government source selection information and our ability to provide compensation to certain former government officials;

Leidos Holdings, Inc. Annual Report - 13

Table of Contents

PART I

• the Civil False Claims Act, which provides for substantial civil penalties for violations, including for submission of a false or fraudulent claim to the U.S. government for payment or approval;

• the False Statements Act, which imposes civil and criminal liability for making false statements to the U.S. government; and

• the U.S. government Cost Accounting Standards ("CAS"), which imposes accounting requirements that govern our right to reimbursement under certain cost-based U.S. government contracts.

These regulations impose a broad range of requirements, many of which are unique to government contracting, including various procurement, import and export, security, contract pricing and cost, contract termination and adjustment and audit requirements. Among other things, these laws and regulations:

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

• define allowable and unallowable costs and otherwise govern our right to reimbursement under various cost-type U.S. government contracts;

• require compliance with U.S. government CAS;

• require reviews by the Defense Contract Audit Agency ("DCAA"), Defense Contract Management Agency ("DCMA") and other U.S. government agencies of compliance with government requirements for a contractor’s business systems;

• restrict the use and dissemination of and require the protection of unclassified contract-related information and information classified for national security purposes and the export of certain products and technical data; and

• require us not to compete for work if an actual or potential organizational conflict of interest, as defined by these laws and regulations, related to such work exists and/or cannot be appropriately mitigated, neutralized or avoided.

The U.S. government may revise its procurement practices or adopt new contract rules and regulations at any time. In order to help ensure compliance with these complex laws and regulations, all of our employees are required to complete ethics and other compliance trainings relevant to their position.

Privacy and Data Security Laws

Some of our operations and service offerings involve access to and use by us of personally identifiable information and/or protected health information. These activities are regulated by extensive federal, state and international privacy and data security laws requiring organizations to provide certain privacy protections and security safeguards for such information. For example:

• the European Union's ("EU’s") General Data Protection Regulation (“GDPR”), which took effect in May 2018, has created new compliance obligations for companies that process personal data of EU data subjects, which require investment into ongoing data protection activities and documentation requirements, and creates the potential for significantly increased fines for noncompliance;

• the United Kingdom’s (“UK’s”) General Data Protection Regulation, which took effect on January 1, 2021, creates similar compliance obligations for companies that process personal data of UK data subjects as are imposed by the EU GDPR;

• the California Consumer Privacy Act of 2018 (“CCPA”), which took effect on January 1, 2020, provides new consumer privacy rights to natural persons residing in California by regulating the processing of personal information of California residents and increasing the obligations on businesses in connection with such activities;

• the California Privacy Rights Act (“CPRA”), which took effect in most material respects on January 1, 2023. The CPRA modifies the CCPA significantly, including by expanding consumers’ rights with respect to certain sensitive personal information, extending the scope of the CCPA to include employees and job applicants residing in California and creating a new state agency to oversee implementation and enforcement efforts; and

PART I

• the Health Insurance Portability and Accountability Act, as amended by the Health Information Technology for Economic and Clinical Health Act, establishes privacy and security compliance obligations with respect to the processing of protected health information by covered entities and business associates, which require investment in technical and organizational compliance measures and creates the potential for substantial fines for noncompliance.

In your evaluation of our company and business, you should carefully consider the risks and uncertainties described below, together with information disclosed elsewhere in this Annual Report on Form 10-K, including our consolidated financial statements and the related notes and "Management's Discussion and Analysis of Financial Condition and Results of Operations" in Part II of this Annual Report, and other documents we file with the SEC. The risks and uncertainties described below are those that we have identified as material but are not the only risks and uncertainties facing us. If any of these risks or uncertainties actually occurs, our business, financial condition or operating results could be materially harmed and our stock price could decline. Our business is also subject to general risks and uncertainties that affect many other companies, such as our ability to collect receivables, overall U.S. and global economic and industry conditions, geopolitical events, changes in laws or accounting rules, fluctuations in interest, exchange rates and inflation, terrorism, international conflicts, major health concerns, climate change or other disruptions of expected economic and business conditions. Additional risks and uncertainties not currently known to us or that we currently believe are immaterial also may materially harm our business, financial condition or operating results and result in a decline in our stock price.

Summary of Risk Factors

This risk factor summary contains a high-level summary of risks associated with our business. It does not contain all of the information that may be important to you, and you should read this risk factor summary together with the more detailed discussion of risks and uncertainties set forth following this summary. A summary of our risks includes, but is not limited to, the following:

• We depend on government agencies as our primary customers and if our reputation or relationships with these agencies were harmed, our future revenues and growth prospects could be adversely affected.

• A decline in the U.S. government budget, changes in spending or budgetary priorities or delays in contract awards may significantly and adversely affect our future revenues and limit our growth prospects.

• Because we depend on U.S. government contracts, a delay in the completion of the U.S. government’s budget and appropriations process could delay procurement of the products, services and solutions we provide and adversely affect our future revenues.

• Due to the competitive process to obtain contracts and the likelihood of bid protests, we may be unable to achieve or sustain revenue growth and profitability.

• The U.S. government may terminate, cancel, modify or curtail our contracts at any time prior to their completion and, if we do not replace them, this may adversely affect our future revenues and profitability.

• We face intense competition that can impact our ability to obtain contracts and therefore affect our future revenues and growth prospects.

• Our failure to comply with various complex procurement rules and regulations could result in our being liable for penalties, including termination of our U.S. government contracts, disqualification from bidding on future U.S. government contracts and suspension or debarment from U.S. government contracting.

• The U.S. government may adopt new contract rules and regulations or revise its procurement practices in a manner adverse to us at any time.

• As a U.S. government contractor, our partners and we are subject to reviews, audits and cost adjustments by the U.S. government, which could adversely affect our profitability, cash position or growth prospects if resolved unfavorably to us.

• Our business is subject to governmental review and investigation, which could adversely affect our financial position, operating results and growth prospects.

• Investigations, audits, claims, disputes, enforcement actions, litigation, arbitration or other legal proceedings could require us to pay potentially large damage awards and could be costly to defend, which would adversely affect our cash balances and profitability, and could damage our reputation.

Leidos Holdings, Inc. Annual Report - 16

Table of Contents

PART I

• Our business and operations expose us to numerous legal and regulatory requirements, and any violation of these requirements could harm our business.

• Our business is subject to complex and evolving laws and regulations regarding data privacy and security which could subject us to investigations, claims or monetary penalties against us, require us to change our business practices or otherwise adversely affect our revenues and profitability.

• The extent to which our business will be adversely affected by COVID-19 or other health epidemics, pandemics and similar outbreaks is highly uncertain and cannot be predicted.

• Misconduct of employees, subcontractors, agents, suppliers, business partners or joint ventures and others working on our behalf could cause us to lose existing contracts or customers and adversely affect our ability to obtain new contracts and customers and could have a significant adverse impact on our business and reputation.

• A failure to attract, train, retain and motivate skilled employees, including our management team, would adversely affect our ability to execute our strategy and may disrupt our operations.

• We may not realize the full amounts reflected in our backlog as revenues, which could adversely affect our expected future revenues and growth prospects.

• Our earnings and profitability may vary based on the mix of our contracts and may be adversely affected by our failure to estimate and manage costs, time and resources accurately.

• We use estimates in recognizing revenues, and if we make changes to estimates used in recognizing revenues, our profitability may be adversely affected.

• Cybersecurity breaches and other information security incidents could negatively impact our business and financial results, impair our ability to effectively provide our services to our clients and cause harm to our reputation or competitive position.

• Internal system or service failures, or failures in the systems or services of third parties on which we rely, could disrupt our business and impair our ability to effectively provide our services and products to our customers, which could damage our reputation and adversely affect our revenues and profitability.

• Our business is subject to disruption caused by physical or transition risks that could adversely affect our operations, profitability and overall financial position.

• Customer systems failures could damage our reputation and adversely affect our revenues and profitability.

• Our success depends, in part, on our ability to work with complex and rapidly changing technologies to meet the needs of our customers.

• We have classified contracts with the U.S. government, which may limit investor insight into portions of our business.

• We have made and continue to make acquisitions, investments, joint ventures and divestitures that involve numerous risks and uncertainties.

• Goodwill and other intangible assets represent significant assets on our balance sheet and any impairment of these assets could negatively impact our results of operations.

• We depend on our teaming arrangements and relationships with other contractors and subcontractors. If we are not able to maintain these relationships, or if these parties fail to satisfy their obligations to us or the customer, our revenues, profitability and growth prospects could be adversely affected.

• Our services and operations sometimes involve using, handling or disposing of hazardous substances, which could expose us to potentially significant liabilities.

Our common stock is listed on the New York Stock Exchange ("NYSE") under the ticker symbol "LDOS."

Holders of Common Stock

As of February 7, 2023, there were approximately 19,798 holders of record of Leidos common stock. The number of stockholders of record of our common stock is not representative of the number of beneficial owners due to the fact that many shares are held by depositories, brokers or nominees.

Dividend Policy

During fiscal 2022 and 2021, we declared and paid quarterly dividends totaling $1.44 and $1.40 per share, respectively, of Leidos common stock. We currently intend to continue paying dividends on a quarterly basis, although the declaration of any future dividends will be determined by our Board of Directors and will depend on many factors, including available cash, estimated cash needs, earnings, financial condition, operating results and capital requirements, as well as limitations in our contractual agreements, applicable law, regulatory constraints, industry practice and other business considerations that the Board of Directors considers relevant. Our ability to declare and pay future dividends on Leidos stock may be restricted by the provisions of Delaware law and covenants in our then-existing indebtedness arrangements.

Purchases of Equity Securities

In February 2022, our Board of Directors authorized a share repurchase program of up to 20 million shares of our outstanding common stock. The shares may be repurchased from time to time in one or more open market repurchases or privately negotiated transactions, including accelerated share repurchase transactions. The actual timing, number and value of shares repurchased under the program will depend on a number of factors, including the market price of Leidos common stock, general market and economic conditions, applicable legal requirements, compliance with the terms of our outstanding indebtedness and other considerations. There is no assurance as to the number of shares that will be repurchased, and the repurchase program may be suspended or discontinued at any time at our Board of Directors' discretion. This share repurchase authorization replaces the previous share repurchase authorization announced in February 2018. As of December 30, 2022, the maximum number of shares that may yet be repurchased under the program was 15,203,974.

For the three months ended December 30, 2022, there were no repurchases of our common stock.

Overview

We are a FORTUNE 500® technology, engineering, and science company that provides services and solutions in the defense, intelligence, civil and health markets, both domestically and internationally. We bring domain-specific capabilities and innovations to customers in each of these markets by leveraging five technical core capabilities: digital modernization, cyber operations, mission software systems, integrated systems and mission operations. Our customers include the U.S. Department of Defense ("DoD"), the U.S. Intelligence Community, the U.S. Department of Homeland Security, the Federal Aviation Administration, the Department of Veterans Affairs and many other U.S. civilian, state and local government agencies, foreign government agencies and commercial businesses. Approximately 8% of our revenues and tangible long-lived assets are generated by or owned by entities located outside of the United States. We operate in three reportable segments: Defense Solutions, Civil and Health. Additionally, we separately present the unallocable costs associated with corporate functions as Corporate.

Effective July 3, 2021, certain contracts were reassigned from the Defense Solutions reportable segment to the Civil reportable segment. Impact on the first half of fiscal 2021 segment results were determined to be immaterial and have not been recast to reflect this change.

For additional information regarding our reportable segments, see “Business” in Part I and "Note 20—Business Segments" of the notes to the consolidated financial statements contained within this Annual Report on Form 10-K.

Our significant initiatives include the following:

• achieving annual revenue growth through internal collaboration and better leveraging of key differentiators across our company and the deployment of resources and investments into higher growth markets;

• increasing headcount and internal direct labor content on our contract portfolio;

• continued improvement in our back-office infrastructure and related business processes for greater effectiveness and efficiency across all business functions; and

• disciplined deployment of our cash resources and use of our capital structure to enhance shareholder value while retaining an appropriate amount of financial leverage.

Sales Trend. For fiscal 2022, revenues increased $0.7 billion, or 5%, compared to fiscal 2021, primarily due to a net increase in volumes on certain programs, program wins and a net increase in revenues related to our business acquisitions. We also received $28 million in recoveries related to stop work orders on certain programs as a result of COVID-19. The increase was partially offset by the completion of certain contracts and unfavorable exchange rate movements.

Operating Expenses and Income Trend. For fiscal 2022, operating expenses increased by $0.7 billion, or 6%, compared to fiscal 2021. Operating margin for fiscal 2022 was 7.6% compared to 8.4% for fiscal 2021. Operating income was $1,088 million, a $64 million decrease compared to fiscal 2021. The decrease in operating income was primarily attributable to the completion of certain contracts, increase in legal fees and settlement costs and impairment charges of $37 million related to our ongoing facility rationalization efforts. The decrease in operating income was partially offset by program wins and $28 million in recoveries related to stop work orders on certain programs as a result of COVID-19.

From a macroeconomic perspective, our industry is under general competitive pressures associated with spending from our largest customer, the U.S. government, and requires a high level of cost management focus to allow us to remain competitive. Although the U.S. Presidential Administration has not indicated a desire to reduce spending in the defense and homeland security sectors, the likelihood, extent and duration of current spending levels in these areas remains unclear. We continue to review our cost structure against our anticipated sales and undertake cost management actions and efficiency initiatives where necessary.

COVID-19

For fiscal 2022, the COVID-19 pandemic did not have a material impact to revenues and operating income, other than the receipt of $28 million in recoveries, within our Health segment related to stop work orders on certain programs. The volume of global passenger air travel remains below pre-pandemic levels, which continues to impact the operations of our Security Enterprise Solutions reporting unit. The full extent of the impact of the COVID-19 pandemic on our operational and financial performance, including our ability to execute on programs in the expected timeframe, will depend on future developments, including the duration and spread of the pandemic and the distribution of vaccines, all of which are uncertain and cannot be predicted.

Business Environment and Trends

U.S. Government Markets

In fiscal 2022, we generated approximately 86% of our total revenues from contracts with the U.S. government, either as a prime contractor or a subcontractor to other contractors engaged in work for the U.S. government. Revenues under contracts with the DoD and U.S. Intelligence Community, including subcontracts under which the DoD or the U.S. Intelligence Community is the ultimate purchaser, represented approximately 44% of our total revenues for fiscal 2022. Accordingly, our business performance is affected by the overall level of U.S. government spending, especially national security, homeland security and intelligence spending, and the alignment of our service and product offerings and capabilities with current and future budget priorities of the U.S. government.

President Biden signed the $1.7 trillion GFY 2023 omnibus spending bill into law on December 29, 2022. The omnibus spending bill funds the federal government through September 30, 2023. The bill includes $772.5 billion in non-defense spending and $858.4 billion in defense spending. The bill also includes $85 billion in emergency spending not included in the discretionary amount. The new 118th Congress will begin to work on the GFY 2024 appropriations bills in the spring of 2023.

Trends in the U.S. government contracting process, including a shift towards multiple-awards contracts, in which certain contractors are preapproved using IDIQ and U.S. General Services Administration ("GSA") contract vehicles, have increased competition for U.S. government contracts, reduced backlogs by shortening periods of performance on contracts and increased pricing pressure. We expect that a majority of the business that we seek in the foreseeable future will be awarded through a competitive bidding process. For more information on these risks and uncertainties, see “Risk Factors” in Part I of this Annual Report on Form 10-K.

International Markets

Sales to customers in international markets represented approximately 8% of total revenues for fiscal 2022. Our international customers include foreign governments and their agencies. Our international business increases our exposure to international markets and the associated international regulatory, foreign currency exchange rate and geopolitical risks.

Changes in international trade policies, including higher tariffs on imported goods and materials, may increase our procurement costs of certain IT hardware used both on our contracts and for internal use. However, we expect to recover certain portions of these higher tariffs through our cost-plus contracts. While we evaluate the impact of higher tariffs, currently, we do not expect tariffs to have a significant impact to our business.

Key Performance Measures

The primary financial performance measures we use to manage our business and monitor results of operations are revenue, operating income, cash flows from operations and diluted earnings per share. Bookings and backlog are also useful measures for management and investors to evaluate our performance and potential future revenues. In addition, we consider business performance by contract type to be useful to management and investors when evaluating our operating income and margin performance.

Results of Operations

Our results of operations for the periods presented were as follows:

NM - Not meaningful

Segment and Corporate Results

The increase in revenues for fiscal 2022 as compared to fiscal 2021 was primarily attributable to program wins, a net increase in volumes on certain programs and a $63 million net increase in revenues related to our acquisitions made in the second and third quarters from the prior year and the Cobham Special Mission acquisition made in the current year. The increase was partially offset by the completion of certain contracts, contracts that were reassigned from Defense Solutions reportable segment to the Civil reportable segment during the third quarter of fiscal 2021 and $95 million related to unfavorable exchange rate movements.

The decrease in operating income for fiscal 2022 as compared to fiscal 2021 was primarily attributable to the completion of certain contracts, net write-downs on certain contracts, increased amortization expense of $8 million and $6 million related to unfavorable exchange rate movements. Fiscal 2022 also included impairment charges of $12 million related to our ongoing facility rationalization efforts (see "Note 10—Leases"). The decrease was partially offset by program wins and a net increase in volumes on certain programs.

PART II

The increase in revenues for fiscal 2022 as compared to fiscal 2021 was primarily attributable to program wins, a net increase in program volumes and contracts that were reassigned from Defense Solutions reportable segment to the Civil reportable segment during the third quarter of fiscal 2021. The increase was partially offset by the completion of certain contracts and $12 million of unfavorable exchange rate movements.

The decrease in operating income for fiscal 2022 as compared to fiscal 2021 was primarily attributable to a $19 million increase in legal fees and settlement costs resulting from an adverse arbitration ruling related to the 2016 acquisition of the Information Systems & Global Solutions business (“IS&GS Business”) from Lockheed Martin and impairment charges of $14 million related to our ongoing facility rationalization efforts (see "Note 10—Leases"). The decreases were partially offset by a net increase in program volumes. Operating income for fiscal 2021 included a $26 million benefit from a legal reserve adjustment related to the Mission Support Alliance joint venture (see "Note 1—Nature of Operations and Basis of Presentation").

The increase in revenues for fiscal 2022 as compared to fiscal 2021 was primarily attributable to a net increase in program volumes, program wins and $28 million in recoveries related to stop work orders on certain programs as a result of COVID-19. The increase was partially offset by the completion of certain contracts.

The decrease in operating income for fiscal 2022 as compared to fiscal 2021 was primarily attributable to a net decrease in volumes on higher margin programs and the completion of certain contracts. The decrease was partially offset by $28 million in recoveries related to stop work orders on certain programs as a result of COVID-19 and program wins.

The increase in operating loss for fiscal 2022 as compared to fiscal 2021 was primarily attributable to an increase in legal costs partially offset by lower acquisition and integration costs.

Equity earnings of non-consolidated subsidiaries

We have certain non-controlling ownership interests in equity method investments. For fiscal 2022 and fiscal 2021 we recorded earnings of $12 million and $20 million, respectively, from our equity method investments.

Leidos Holdings, Inc. Annual Report - 47

Table of Contents

PART II

Non-Operating Expense, Net

Non-operating expense, net increased $17 million for fiscal 2022 as compared to fiscal 2021, primarily due to higher interest expense driven by increased interest rates.

Provision for Income Taxes

Our effective tax rate was 21.8%, and 21.5% in fiscal 2022 and 2021, respectively. The effective tax rate for fiscal 2022 and 2021 were both favorably impacted primarily by federal research tax credits and excess tax benefits related to employee stock-based payment transactions.

Beginning in 2022, the Tax Cuts and Jobs Act of 2017 ("TCJA") eliminated the option to currently deduct certain research and development costs for tax purposes and requires taxpayers to capitalize and amortize research costs over five years. Based upon our interpretation of the law as enacted, we recorded the estimated fiscal 2022 impact, resulting in increases of $130 million to both our income taxes payable and net deferred tax assets, and our fiscal 2022 unrecognized tax benefits increased by $91 million with a corresponding increase to net deferred tax assets. We expect this TCJA provision to have a similar impact to income taxes payable, unrecognized tax benefits and net deferred tax assets during fiscal 2023. The actual impact will depend on the amount of research and development costs the Company will incur, whether Congress modifies or repeals this provision and whether new guidance and interpretive rules are issued by the U.S. Treasury, among other factors.

Bookings and Backlog

We had net bookings of $15.4 billion and $15.5 billion during fiscal 2022 and 2021, respectively. Net bookings represent the estimated amount of revenue to be earned in the future from funded and unfunded contract awards that were received during the year, net of any adjustments to previously awarded backlog amounts. We calculate net bookings as the year’s ending backlog, plus the year’s revenues, less the prior year’s ending backlog and any impacts from foreign currency or acquisitions and divestitures.

Backlog represents the estimated amount of future revenues to be recognized under negotiated contracts. We segregate our backlog into two categories as follows:

• Funded Backlog. Funded backlog for contracts with the U.S. government represents the value on contracts for which funding is appropriated less revenues previously recognized on these contracts. Funded backlog for contracts with non-U.S. government entities and commercial customers represents the estimated value on contracts, which may cover multiple future years, under which we are obligated to perform, less revenues previously recognized on the contracts.

*•*Negotiated Unfunded Backlog. Negotiated unfunded backlog represents estimated amounts of revenue to be earned in the future from contracts for which funding has not been appropriated and unexercised priced contract options. Negotiated unfunded backlog does not include unexercised option periods and future potential task orders expected to be awarded under IDIQ, GSA Schedule or other master agreement contract vehicles, with the exception of certain IDIQ contracts where task orders are not competitively awarded and separately priced but instead are used as a funding mechanism, and where there is a basis for estimating future revenues and funding on future anticipated task orders.

The estimated value of our total backlog for the periods presented was as follows:

Leidos Holdings, Inc. Annual Report - 48

Table of Contents

PART II

Total backlog at December 30, 2022, and December 31, 2021, included $610 million and $800 million, respectively, of backlog acquired during the year through business combinations in our Defense Solutions reportable segment.

The increase in backlog as of December 30, 2022, as compared to December 31, 2021, included an unfavorable impact of $233 million due to the movements in the British pound and Australian dollar when compared to the U.S. dollar.

Bookings and backlog fluctuate from period to period depending on our success rate in winning contracts and the timing of contract awards, renewals, modifications and cancellations, as well as foreign currency movements. Contract awards may be negatively impacted by ongoing industry-wide delays in procurement decisions and budget cuts by the U.S. government as discussed in “Business Environment and Trends” in this Annual Report on Form 10-K.

We expect to recognize a substantial portion of our funded backlog as revenues within the next 12 months. However, the U.S. government may cancel any contract at any time through a termination for the convenience of the U.S. government. In addition, certain contracts with commercial or non-U.S. government customers may include provisions that allow the customer to cancel at any time. Most of our contracts have cancellation terms that would permit us to recover all or a portion of our incurred costs and fees for work performed.

Contract Types

Our earnings and profitability may vary materially depending on changes in the proportionate amount of revenues derived from each type of contract. For a discussion of the types of contracts under which we generate revenues, see “Business—Contract Types” in Part I of this Annual Report on Form 10-K. Revenues by contract type as a percentage of our total revenues for the periods presented were as follows:

Liquidity and Capital Resources

Overview of Liquidity

As of December 30, 2022, we had $516 million in cash and cash equivalents. Additionally, we have an unsecured revolving credit facility which can provide up to $750 million in additional borrowing, if required. During fiscal 2022 and 2021, there were no borrowings outstanding under the credit facilities.

At December 30, 2022 and December 31, 2021, we had outstanding debt of $4.9 billion and $5.1 billion, respectively. On May 6, 2022, we entered into a Term Loan Agreement which provided for a senior unsecured term loan facility in an aggregate principal amount of $380 million.

We have a commercial paper program in which we may issue short-term unsecured commercial paper notes not to

exceed $750 million and have maturities of up to 397 days from the date of issuance (see "Note 13—Debt"). As of December 30, 2022, we did not have any commercial paper notes outstanding.

We made principal payments on our debt of $545 million, $106 million and $731 million during fiscal 2022, 2021 and 2020, respectively. This activity included required principal payments on our term loans of $476 million, $96 million and $72 million during fiscal 2022, 2021 and 2020, respectively. During fiscal 2020, we made $4,925 million of principal repayments for outstanding debt and retired the $450 million senior notes. The notes outstanding as of December 30, 2022, contain financial covenants and customary restrictive covenants. We were in compliance with all covenants as of December 30, 2022.

PART II

Interest on our Credit Facilities is calculated based on the London Interbank Offered Rate (“LIBOR”). On July 27, 2017, the U.K.’s Financial Conduct Authority announced that LIBOR would be discontinued or become unavailable as a reference rate by the end of 2021 and LIBOR will be fully discontinued or become unavailable as a benchmark rate by June 2023. In December 2022, the FASB issued guidance which provides relief for entities with such LIBOR denominated credit instruments so that entities may continue to account for contract modifications as a continuation of the existing contract and the continuation of the hedge accounting arrangement through December 31, 2024.

Although our Credit Facilities include mechanics to facilitate the adoption by us and our lenders of an alternative benchmark rate for use in place of LIBOR, no assurance can be made that such alternative benchmark rate will perform in a manner similar to LIBOR or result in interest rates that are at least as favorable to us as those that would have resulted had LIBOR remained in effect, which could result in an increase in our interest expense and other debt service obligations. In addition, the overall credit market may be disrupted as a result of the replacement of LIBOR or in the anticipation thereof, which could have an adverse impact on our ability to refinance, reprice, or amend our existing indebtedness or incur additional indebtedness on favorable terms.

We paid dividends of $199 million, $199 million and $196 million for fiscal 2022, 2021 and 2020, respectively.

During fiscal 2022, we sold $209 million of accounts receivable under accounts receivable purchase agreements and received proceeds of $209 million (see "Note 6—Receivables"). There were no sales of accounts receivable in the second half of fiscal 2022.

We may from time to time seek to retire or purchase our outstanding debt through cash purchases in the open market, privately negotiated transactions or otherwise. Such repurchases, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved may be material.

Stock repurchases of Leidos common stock may be made on the open market or in privately negotiated transactions with third parties including through accelerated share repurchase ("ASR") agreements. Whether repurchases are made and the timing and actual number of shares repurchased depends on a variety of factors including price, corporate capital requirements, other market conditions and regulatory requirements. The repurchase program may be accelerated, suspended, delayed or discontinued at any time.

During fiscal 2021 and 2020, we made open market repurchases of our common stock for an aggregate purchase price of $237 million and $67 million, respectively. There were no open market share repurchases in fiscal 2022.

In fiscal 2022, we entered into an ASR with a financial institution to repurchase shares of our outstanding common stock. We paid $500 million to the financial institution and received 4.8 million shares (see "Note 16—Earnings Per Share" of the notes to the consolidated financial statements contained within this Annual Report on Form 10-K). All shares delivered were immediately retired.

During fiscal 2022, we made a $25 million payment in connection with the adverse arbitration ruling related to the 2016 acquisition of the IS&GS Business from Lockheed Martin.

Beginning in 2022, a provision in the TCJA which eliminated the option to currently deduct research and development costs for tax purposes and requires taxpayers to capitalize and amortize the costs over five years became effective. We anticipate our tax cash payments to increase by $300 million in 2023 primarily to cover both the 2022 and 2023 tax obligations related to this provision. The actual impact will depend on the amount of research and development costs the Company will incur during fiscal 2023 and whether new guidance and interpretive rules are issued by the U.S. Treasury, among other factors. We will continue to assess our liquidity needs as the tax legislation and pandemic evolve.

For the next 12 months, we anticipate that we will be able to meet our liquidity needs, including servicing our debt, through cash generated from operations, available cash balances, sales of accounts receivable and, if needed, borrowings from our revolving credit facility and commercial paper program.

PART II

Summary of Cash Flows

The following table summarizes cash flow information for the periods presented:

Net cash provided by operating activities decreased $45 million for fiscal 2022 as compared to fiscal 2021. The decrease was primarily due to a $25 million payment in connection with the adverse arbitration ruling related to the 2016 acquisition of the IS&GS Business from Lockheed Martin and $23 million of payments for other legal and tax settlements occurred during the current year, partially offset by favorable working capital changes.

Net cash used in investing activities decreased $417 million for fiscal 2022 as compared to fiscal 2021. The decrease was primarily due to $430 million of less cash paid related to our business acquisitions in current year as compared to prior year and $15 million of proceeds received from the sale of Aviation & Missile Solutions LLC in the current year. The decrease was partially offset by $25 million of higher capital expenditures in the current year.

Net cash used in financing activities increased $752 million for fiscal 2022 as compared to fiscal 2021. The increase was primarily due to $439 million increase in principal payments of our debt, an increase of $272 million in stock repurchases primarily attributable to the accelerated share repurchase agreement and a $45 million decrease in net capital contributions received from our non-controlling interest.

Off-Balance Sheet Arrangements

We have outstanding performance guarantees and cross-indemnity agreements in connection with certain aspects of our business. We have letters of credit outstanding principally related to performance guarantees on contracts and surety bonds outstanding principally related to performance and subcontractor payment bonds. We also have future lease commitments for the use of certain aircraft as described in "Note 21—Commitments and Contingencies" of the notes to the consolidated financial statements contained within this Annual Report on Form 10-K. These arrangements have not had, and management does not believe it is likely that they will in the future have, a material effect on our liquidity, capital resources, operations or financial condition.

Contractual Obligations

Our future contractual obligations are related to debt, finance and operating leases, long-term liabilities under deferred compensation arrangements, purchase obligations for long-term purchases and service agreements and other liabilities. For more information, see "Note 10—Leases", "Note 13—Debt", “Note 19—Retirement Plans” and "Note 21—Commitments and Contingencies" of the notes to the consolidated financial statements contained within this Annual Report on Form 10-K.

We have interest payments related to our outstanding debt and finance leases. As of December 30, 2022, future scheduled interest payments on our outstanding debt and finance leases were $195 million, expected to be paid in fiscal 2023 and $946 million expected to be paid thereafter.

As of December 30, 2022, future payments on our deferred compensation arrangements and purchase obligations for long-term purchases and service agreements were $36 million, expected to be paid in fiscal 2023, and $120 million expected to be paid thereafter. Our future payments do not include $92 million of income tax liabilities as a result of uncertain tax positions arising from certain provisions of the TCJA becoming effective in 2022, and the timing of such payments, if any, cannot be reasonably estimated. For additional information, see "Note 18—Income Taxes" of the notes to the consolidated financial statements contained within this Annual Report on Form 10-K.

Commitments and Contingencies

We are subject to a number of reviews, investigations, claims, lawsuits, other uncertainties and future obligations related to our business. For a discussion of these items, see "Note 10—Leases" and "Note 21—Commitments and Contingencies" of the notes to the consolidated financial statements contained within this Annual Report on Form 10-K.

Critical Accounting Estimates

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which are prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"). The preparation of these financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingencies at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting periods. Management evaluates these estimates and assumptions on an ongoing basis. Our estimates and assumptions have been prepared by management on the basis of the most current and best available information. The results of these estimates form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from these estimates under different assumptions and conditions.

We have identified the following accounting policies as critical because they require significant judgments and assumptions about highly complex and inherently uncertain matters and the use of reasonably different estimates and assumptions could have a material impact on our results of operations or financial condition.

• Revenue Recognition

• Goodwill and Intangible Assets

Revenue Recognition

We perform work under various types of contracts, which include firm-fixed-price ("FFP"), time-and-materials ("T&M"), fixed-price-level-of-effort ("FP-LOE"), cost-plus-fixed-fee ("CPFF"), cost-plus-award-fee, cost-plus-incentive-fee and fixed-price-incentive-fee contracts. Some of these contracts require us to use estimates of the revenue and cost associated with the design, manufacture and delivery of our products and services for the purposes of recognizing revenue.

We also evaluate whether two or more contracts should be combined and accounted for as a single contract, including the task orders issued under an IDIQ award. In addition, we assess contract modifications to determine whether changes to existing contracts should be accounted for as part of the original contract or as a separate contract. Some of our cost-plus and fixed-price contracts contain award fees, incentive fees or other provisions that may either increase or decrease the transaction price. These variable amounts generally are awarded upon achievement of certain performance metrics, program milestones or cost targets and can be based upon customer discretion. We estimate variable consideration at the most probable amount that we expect to be entitled to, based on the assessment of the contractual variable fee criteria, complexity of work and related risks, extent of customer discretion, amount of variable consideration received historically and the potential of significant reversal of revenue.

Leidos Holdings, Inc. Annual Report - 53

Table of Contents

PART II

On FFP contracts requiring system integration and cost-plus contracts with variable consideration, revenue is recognized over time generally using a method that measures the extent of progress towards completion of a performance obligation, principally using a cost-input method (referred to as the cost-to-cost method). Under the cost-to-cost method, revenue is recognized based on the proportion of total costs incurred to estimated total costs-at-completion ("EAC"). A performance obligation's EAC includes all direct costs such as materials, labor, subcontract costs, overhead and a ratable portion of general and administrative costs. In addition, an EAC of a performance obligation includes future losses estimated to be incurred on onerous contracts, as and when known.

For the impacts of changes in estimates on our contracts, (see "Note 3—Summary of Significant Accounting Policies").

Goodwill and Intangible Assets

Goodwill represents the excess of the fair value of consideration transferred, plus the fair value of any non-controlling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. We recognize purchased intangible assets in connection with our business acquisitions at fair value on the acquisition date.

Goodwill is not amortized, but instead is tested annually, at the beginning of the fourth quarter, for impairment at the reporting unit level and may be tested more frequently if events or circumstances indicate that the carrying value may not be recoverable. Intangible assets with indefinite lives are not amortized but are assessed for impairment at the beginning of the fourth quarter and whenever events or changes in circumstances indicate that the carrying value may not be recoverable.

Goodwill and intangible assets, net, collectively represent 59% and 60% of our total assets as of December 30, 2022 and December 31, 2021, respectively.

We may perform qualitative or quantitative analysis to test for impairment. Qualitative factors may include macroeconomic, industry and market considerations, overall financial performance, industry, legal and other relevant events and factors affecting the reporting unit.

For quantitative analysis, we use discounted cash flow models and market multiple analyses in order to estimate reporting unit fair values. Discounted cash flow analyses rely on significant judgement and assumptions about expected future cash flows, weighted-average cost of capital, discount rates, expected long-term growth rates and operating margins. These assumptions are based on estimates of future sales and earnings after considering such factors as general market conditions, customer budgets, existing firm and future orders, changes in working capital, long term business plans and recent operating performance. Market multiple analyses incorporate significant judgments and assumptions related to the selection of guideline public companies, our forecast earnings before interest, taxes, depreciation and amortization (“EBITDA”), forecast EBITDA of guideline public companies and control premium estimates.

We performed our annual test for impairment as of October 1, 2022, which resulted in no impairments being identified. However, through this analysis we determined that our Security Enterprise Solutions reporting unit within the Civil reportable segment, which holds goodwill in the amount of $899 million as of December 30, 2022, was at risk of future impairment. The estimated fair value of the Security Enterprise Solutions reporting unit exceeded the carrying value by approximately 13%. Operations of the reporting unit rely heavily on the sales and servicing of security and detection products, which have been negatively impacted by COVID-19. The forecasts utilized to estimate the fair value of the Security Enterprise Solutions reporting unit assume continued global operations in all of our existing markets and a gradual improvement in the global aviation security product and related service sales, reaching pre-COVID-19 levels by fiscal 2025. The fair value of the reporting unit is also negatively impacted by rising interest rate factored into cost of capital. In the event that there are significant unfavorable changes to the forecasted cash flows of the reporting unit (including if the impact of COVID-19 on passenger travel levels is more prolonged or severe than what is incorporated into our forecast), terminal growth rates or the cost of capital used in the fair value estimates, we may be required to record a material impairment of goodwill or intangible assets at a future date.

PART II

We are exposed to certain market risks in the normal course of business. Our current market risk exposures are primarily related to interest rates and foreign currency fluctuations. The following information about our market sensitive financial instruments contains forward-looking statements.

Interest Rate Risk

Our exposure to market risk for changes in interest rates relates primarily to long-term debt obligations and derivatives. Our policy authorizes, with Board of Directors' approval, the limited use of derivative instruments to hedge specific interest rate risks.

Debt and derivatives

At December 30, 2022 and December 31, 2021, we had $4.9 billion and $5.1 billion, respectively, of debt, which included $1.5 billion and $1.7 billion, respectively, related to our senior unsecured term loans that have a variable stated interest rate that is determined based on either the London Interbank Offered Rate ("LIBOR") or the Stated Overnight Financing Date ("SOFR") rate plus a margin. As a result, we may experience fluctuations in interest expense.

As of December 30, 2022, we hold $500 million of unsecured notes due May 2023. We anticipate refinancing this obligation during fiscal 2023, at which time we will be subject to current market rates which may vary significantly from the existing rates on our debt.

We have interest rate swap agreements to hedge the cash flows of a portion of our variable rate senior unsecured term loan ("Variable Rate Loan"). Under the terms of the interest rate swap agreements, we receive variable interest payments based on the one-month LIBOR rate and pay interest at a fixed rate. As of December 30, 2022, the notional value of the interest rate swap agreements was $1.0 billion. The interest rate swap agreements effectively converted a portion of our variable rate borrowing to a fixed rate borrowing. The fair value of our interest rate swap agreements with respect to our Variable Rate Loan was an asset of $20 million, as of December 30, 2022, and a liability of $53 million, as of December 31, 2021.

The counterparties to these agreements are financial institutions. We do not hold or issue derivative financial instruments for trading or speculative purposes. We cannot predict future market fluctuations in interest rates and their impact on our interest rate swaps. The net hypothetical 10% movement in the one-month LIBOR or SOFR rate would not have a significant impact on our annual interest expense. For additional information related to our interest rate swap agreements and debt, see "Note 12—Derivative Instruments" and "Note 13—Debt," respectively, of the notes to the consolidated financial statements contained within this Annual Report on Form 10-K.

Cash and Cash Equivalents

As of December 30, 2022 and December 31, 2021, our cash and cash equivalents included investments in several large institutional money market accounts. For fiscal 2022 and fiscal 2021, a hypothetical 10% interest rate movement would not have a significant impact on the value of our holdings or on interest income.

Foreign Currency Risk

Although the majority of our transactions are denominated in U.S. dollars, some of our transactions are denominated in foreign currencies. Our foreign currency exchange rate risk relates to receipts from customers, payments to suppliers and certain intercompany transactions denominated in currencies other than our (or one of our subsidiaries') functional currency. Our foreign operations represented 8% of total revenues for fiscal 2022, 2021 and 2020.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of Leidos Holdings, Inc.

Reston, Virginia

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Leidos Holdings, Inc. and subsidiaries (the "Company") as of December 30, 2022 and December 31, 2021, the related consolidated statements of income, comprehensive income, equity, and cash flows, for the fiscal years ended December 30, 2022, December 31, 2021, and January 1, 2021, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 30, 2022 and December 31, 2021, and the results of its operations and its cash flows for the fiscal years ended December 30, 2022, December 31, 2021, and January 1, 2021, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 30, 2022, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 14, 2023, expressed an unqualified opinion on the Company's internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current-period audit of the financial statements that were communicated or required to be communicated to the audit committee and that (1) relate to accounts or disclosures that are material to the financial statements and (2) involved especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing a separate opinion on the critical audit matters or on the accounts or disclosures to which they relate.

Goodwill Valuation – Security Enterprise Solutions Reporting Unit - Refer to Note 3 and Note 8 to the financial statements

Critical Audit Matter Description

The Company performed a quantitative impairment evaluation of the goodwill for the Security Enterprise Solutions reporting unit by comparing the estimated fair value of the reporting unit to its carrying value. Estimating the fair value of a reporting unit requires the exercise of significant judgment and assumptions including judgments about expected future cash flows, weighted-average cost of capital, discount rates and expected long-term growth rates. Changes in these assumptions could have a significant impact on the fair value of the reporting unit, the amount of any goodwill impairment charge, or both. The goodwill balance was $6,696 million as of December 30, 2022 of which $899 million related to the Security Enterprise Solutions reporting unit. The Company’s accounting policy is to test for impairment on the first day of the fourth quarter of each year and more frequently if events or circumstances indicate that the carrying value may not be recoverable. As a result of the quantitative assessment, the Company concluded that the fair value of the reporting unit exceeded the carrying value by $174 million, or 13%, which resulted in no impairment for the year ended December 30, 2022.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our principal executive officer (our Chairman and Chief Executive Officer) and principal financial officer (our Executive Vice President and Chief Financial Officer), has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e) under the Securities Exchange Act of 1934) as of December 30, 2022. Based upon that evaluation, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures are effective to ensure that information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the U.S. Securities and Exchange Commission ("SEC"). These disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934 is accumulated and communicated to our management, including our principal executive officer and our principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

During the fourth quarter of fiscal 2022, we completed our acquisition of Cobham Special Mission. As part of the ongoing integration of Cobham Special Mission, we are in the process of incorporating the controls and related procedures of these businesses. Other than incorporating controls for Cobham Special Mission, there have been no other changes in our internal control over financial reporting that occurred in the fourth quarter of the period ended December 30, 2022, covered by this Annual Report that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America.

As permitted by the SEC rules, management's assessment and conclusion on the effectiveness of our internal control over financial reporting as of December 30, 2022, excludes an assessment of the internal control over financial reporting of Cobham Special Mission, acquired on October 30, 2022. Cobham Special Mission represents approximately 1.55% of our consolidated total assets, excluding the preliminary value of goodwill and intangible assets related to Cobham Special Mission, at December 30, 2022, and 0.15% and 0.28% of our consolidated revenues and operating income, respectively, for the fiscal year ended December 30, 2022.

Our management, with the participation of our principal executive officer and principal financial officer, has evaluated the effectiveness of our internal control over financial reporting as of December 30, 2022, based on criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Our management has assessed the effectiveness of our internal control over financial reporting as of December 30, 2022, and has concluded that our internal control over financial reporting as of that date was effective.

Deloitte & Touche LLP, an independent registered public accounting firm, audited our consolidated financial statements included in this Annual Report on Form 10-K and our internal control over financial reporting, and that firm’s report on our internal control over financial reporting is set forth below.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of Leidos Holdings, Inc.

Reston, Virginia

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Leidos Holdings, Inc. and subsidiaries (the “Company”) as of December 30, 2022, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 30, 2022, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the fiscal year ended December 30, 2022, of the Company and our report dated February 14, 2023, expressed an unqualified opinion on those financial statements.

As described in Management’s Report on Internal Control Over Financial Reporting, management excluded from its assessment the internal control over financial reporting at Cobham Special Mission, which was acquired on October 30, 2022, and whose financial statements constitute total assets of 1.55%, excluding the preliminary value of goodwill and intangible assets, 0.15% of revenues, and 0.28% of operating income of the consolidated financial statement amounts as of and for the fiscal year ended December 30, 2022. Accordingly, our audit did not include the internal control over financial reporting at Cobham Special Mission.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

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