NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Note 1–Basis of Presentation and Summary of Significant Accounting Policies

Nature of Operations and Basis of Presentation

Leidos Holdings, Inc. ("Leidos"), a Delaware corporation, is a holding company whose direct 100%-owned subsidiary and principal operating company is Leidos, Inc. Leidos, a member of the Fortune 500®, is a dynamic innovation company that is at the forefront of addressing the world’s most challenging issues in national security and health sectors. With a global workforce of approximately 48,000, Leidos is committed to developing smarter technology solutions, particularly for customers in highly regulated industries. Leidos' 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, National Aeronautics and Space Administration ("NASA") and many other U.S. civilian, state and local government agencies, foreign government agencies and commercial businesses. Unless indicated otherwise, references to "we," "us" and "our" refer collectively to Leidos Holdings, Inc. and its consolidated subsidiaries.

During the quarter ended March 29, 2024, we completed a realignment of our segment and reporting structure, which resulted in the identification of four reportable segments: National Security & Digital, Health & Civil, Commercial & International and Defense Systems. We commenced operating and reporting under the new organizational structure effective the first day of fiscal 2024. In addition, we separately present the unallocable costs associated with corporate functions as Corporate. As a result of this change, prior year segment results and disclosures have been recast to reflect the current reportable segment structure.

We have a controlling interest in Mission Support Alliance, LLC ("MSA"), a joint venture with Centerra Group, LLC. We also have a controlling interest in Hanford Mission Integration Solutions, LLC ("HMIS"), the legal entity for the follow-on contract to MSA's contract and a joint venture with Centerra Group, LLC and Parsons Government Services, Inc. The financial results for MSA and HMIS are consolidated into our unaudited condensed consolidated financial statements. The unaudited condensed consolidated financial statements also include the balances of all voting interest entities in which Leidos has a controlling voting interest ("subsidiaries") and a variable interest entity ("VIE") in which Leidos is the primary beneficiary. The consolidated balances of the VIE are not material to the unaudited condensed consolidated financial statements for the periods presented. Intercompany accounts and transactions between consolidated companies have been eliminated in consolidation.

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the rules of the U.S. Securities and Exchange Commission and accounting principles generally accepted in the United States of America ("GAAP"). Certain disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules. The preparation of financial statements in conformity 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, including those relating to estimated profitability of long-term contracts, indirect billing rates, allowances for doubtful accounts, inventories, right-of-use assets and lease liabilities, fair value and impairment of intangible assets and goodwill, income taxes, stock-based compensation expense and contingencies. These estimates have been prepared by management on the basis of the most current and best available information; however, actual results could differ materially from those estimates.

Certain amounts in the prior year financial statements have been reclassified to conform to the current year presentation. We combined "Deferred tax liabilities" into "Other long-term liabilities" on the condensed consolidated balance sheets.

In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments, which consist of normal recurring adjustments, necessary for a fair presentation thereof. The results reported in these unaudited condensed consolidated financial statements are not necessarily indicative of the results that may be expected for the entire year. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Annual Report on Form 10-K filed on February 13, 2024.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Accounting Standards Updates Issued But Not Yet Adopted

ASU 2023-07 Segment Reporting

In November 2023, the FASB issued ASU 2023-07, to improve reportable segment disclosure requirements. This update requires companies to disclose significant segment expense categories that are regularly provided to the chief operating decision maker ("CODM") on an interim and annual basis and expands disclosure requirements for interim reporting. Companies must also disclose how segment measures of profit or loss are used by the CODM.

The amendments in this update are effective for public entities for annual periods beginning after December 15, 2023, and interim periods beginning after December 15, 2024. The amendments should be adopted on a retrospective basis and early adoption is permitted. We will adopt these amendments for annual disclosures in fiscal 2024 and interim disclosures in fiscal 2025.

ASU 2023-09 Income Taxes

In December 2023, the FASB issued ASU 2023-09, to enhance the transparency and usefulness of income tax disclosures. The update requires enhancements to the annual rate reconciliation, including disclosure of specific categories and additional information for reconciling items meeting a quantitative threshold. The update also requires disclosure of income taxes paid disaggregated by federal, state and foreign taxes, and individual jurisdictions meeting a quantitative threshold.

The amendments in this update are effective for public business entities for annual periods beginning after December 15, 2024, and may be adopted on a prospective or retrospective basis. Early adoption is permitted. We are currently evaluating the impacts of this update and plan to adopt these amendments using the prospective approach for annual disclosures in fiscal 2025.

Changes in Estimates on Contracts

Changes in estimates related to contracts accounted for using the cost-to-cost method of accounting are recognized in the period in which such changes are made for the inception-to-date effect of the changes, with the exception of contracts acquired through a business combination, where the adjustment is made for the period commencing from the date of acquisition.

Changes in estimates on contracts were as follows:


	Three Months Ended				Nine Months Ended
	September 27, 2024		September 29, 2023		September 27, 2024		September 29, 2023
	(in millions, except per share data)
Favorable impact	$	58	$	40	$	125	$	102
Unfavorable impact	(28)		(24)		(107)		(62)
Net impact to income before income taxes	$	30	$	16	$	18	$	40

Impact on diluted EPS attributable to Leidos common stockholders	$	0.17	$	0.09	$	0.10	$	0.22

The unfavorable impact for the nine months ended September 27, 2024, included $41 million in write-downs on programs within our UK operations related to cost increases and schedule delays.

The impact on diluted earnings per share ("EPS") attributable to Leidos common stockholders is calculated using the statutory tax rate.

Revenue Recognized from Prior Obligations

Revenue recognized from performance obligations satisfied in previous periods was $78 million and $12 million for the three and nine months ended September 27, 2024, respectively, and $13 million and $14 million for the three and nine months ended September 29, 2023, respectively. The changes primarily relate to revisions of variable consideration including award and incentive fees, and revisions to estimates at completion resulting from changes in contract scope, mitigation of contract risks or true-ups of contract estimates at the end of contract performance.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Cash and Cash Equivalents

Our cash equivalents are primarily comprised of investments in several large institutional money market accounts, with original maturity of three months or less. At September 27, 2024, and December 29, 2023, $91 million and $136 million, respectively, of outstanding payments were included within "Cash and cash equivalents" and "Accounts payable and accrued liabilities" correspondingly on the condensed consolidated balance sheets.

Restricted Cash

We have restricted cash balances, primarily representing advances from customers that are restricted for use on certain expenditures related to that customer's contract. Restricted cash balances are included as "Other current assets" in the condensed consolidated balance sheets. Our restricted cash balances were $141 million and $151 million at September 27, 2024, and December 29, 2023, respectively.

Note 2–Revenues

Remaining Performance Obligations

Remaining performance obligations ("RPO") represent the expected value of exercised contracts, both funded and unfunded, less revenue recognized to date. RPO does not include unexercised option periods and future potential task orders expected to be awarded under indefinite delivery/indefinite quantity ("IDIQ") contracts, General Services Administration 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.

As of September 27, 2024, we had $16 billion of RPO and expect to recognize approximately 66% and 82% over the next 12 months and 24 months, respectively, with the remainder to be recognized thereafter.

Disaggregation of Revenues

We disaggregate revenues by customer-type, contract-type and geographic location for each of our reportable segments.

Disaggregated revenues by customer-type were as follows:


	Three Months Ended September 27, 2024
	National Security & Digital		Health & Civil		Commercial & International		Defense Systems		Total
	(in millions)

Revenues by customer-type, contract-type and geographic location exclude lease income of $21 million and $70 million for the three and nine months ended September 27, 2024, respectively, and $24 million and $69 million for the three and nine months ended September 29, 2023, respectively.

Contract Assets and Liabilities

Performance obligations are satisfied either over time as work progresses or at a point in time. Firm-fixed-price contracts are typically billed to the customer using milestone payments while cost-reimbursable and time and materials contracts are typically billed to the customer on a monthly or bi-weekly basis as indicated by the negotiated billing terms and conditions of the contract. As a result, the timing of revenue recognition, customer billings and cash collections for each contract results in a net contract asset or liability at the end of each reporting period.

Contract assets consist of unbilled receivables, which is the amount of revenue recognized that exceeds the amount billed to the customer. Unbilled receivables exclude amounts billable where the right to consideration is solely subject to the passage of time. Contract liabilities consist of deferred revenue, which represents cash advances received prior to performance for programs and billings in excess of revenue recognized.

The components of contract assets and contract liabilities consisted of the following:


	Balance sheet line item	September 27, 2024		December 29, 2023
		(in millions)
Contract assets - current:
Unbilled receivables	Receivables, net	$	1,137	$	1,041

Contract liabilities - current:
Deferred revenue(1)	Accounts payable and accrued liabilities	$	353	$	442

Contract liabilities - non-current:
Deferred revenue(1)	Other long-term liabilities	$	13	$	21

(1) Certain contracts record revenue net of cost of revenues, and therefore, the respective deferred revenue balance will not fully convert to revenue.

The increase in unbilled receivables was primarily due to revenue recognized on certain contracts, partially offset by the timing of billings. The decrease in deferred revenue was primarily due to revenue recognized during the period, offset by the timing of advanced payments from customers.

For the three and nine months ended September 27, 2024, $45 million and $256 million, respectively, of revenue recognized was included as a contract liability at December 29, 2023. For the three and nine months ended September 29, 2023, $28 million and $215 million, respectively, of revenue recognized was included as a contract liability at December 30, 2022.

Note 3–Goodwill and Intangible Assets

Goodwill

During the quarter ended March 29, 2024, the Company completed a business realignment, which resulted in identification of new reportable segments. The Company commenced operating and reporting under the new organizational structure effective the first day of fiscal 2024 (see "Note 10–Business Segments).

Goodwill was allocated to the new reporting units within our reportable segments based on a relative fair value approach.

The following table presents changes in the carrying amount of goodwill by reportable segment:


	National Security & Digital		Health & Civil		Commercial & International		Defense Systems		Total
	(in millions)
Goodwill at December 30, 2022	$	2,755	$	1,366	$	1,389	$	1,186	$	6,696

Goodwill at September 27, 2024(2)	$	2,758	$	1,366	$	811	$	1,188	$	6,123

(1) Adjustment to goodwill resulting from a measurement period purchase accounting adjustment.

(2) Carrying amount includes accumulated impairment loss of $596 million within the Commercial & International segment.

We evaluate qualitative factors that could cause us to consider whether the estimated fair value of each of our reporting units may be lower than the carrying value and trigger a quantitative assessment, including, but not limited to (i) macroeconomic conditions, (ii) industry and market considerations, (iii) our overall financial performance, including an analysis of our current and projected cash flows, revenues and earnings, (iv) a sustained decrease in share price and (v) other relevant entity-specific events including changes in management, strategy, partners or litigation.

Operations of the Security Enterprise Solutions (“SES”) reporting unit rely heavily on the sales and servicing of security and detection products, which prior to fiscal 2024, have been negatively impacted due to delays in airline travel infrastructure projects as customer budgets recover from the pandemic. During fiscal 2023, the SES reporting unit refined its portfolio and made strategic business decisions to exit certain product offerings, and cease operations in certain countries in order to align the operations of the reporting unit with its strategic business plan. These decisions, along with the delays in airline travel infrastructure projects and higher than anticipated servicing costs, contributed to a significant reduction in the reporting unit’s forecasted revenue and cash flows. Accordingly, we recognized a non-cash goodwill impairment charge of $596 million at the SES reporting unit during the fiscal year ended December 29, 2023. The impairment was recorded within the Commercial & International reportable segment in the condensed consolidated statements of operations. In the event that there are significant unfavorable changes to the forecasted cash flows, forecasted revenue, terminal growth rates or the cost of capital used in the fair value estimates, we may be required to record an additional impairment of goodwill at a future date.

In conjunction with the change in reportable segments in fiscal 2024, the Company evaluated goodwill for impairment both before and after the segment change and determined that goodwill was not impaired.

Our strategic decisions regarding SES’ product offerings and operating regions (see the goodwill discussion above) caused certain technology and in-process research and development intangible assets to be abandoned and the carrying values of certain program intangible assets to become unrecoverable. As a result, for the three and nine months ended September 29, 2023, we recognized intangible asset impairment charges of $79 million. The impairment was recorded to “Asset impairment charges” in the condensed consolidated statements of operations within the Commercial & International reportable segment.

Amortization expense was $37 million and $110 million for the three and nine months ended September 27, 2024, respectively, and $50 million and $153 million for the three and nine months ended September 29, 2023, respectively.

Program intangible assets are amortized over their respective estimated useful lives in proportion to the pattern of economic benefit based on expected future discounted cash flows. Customer relationships and software and technology intangible assets are amortized either on a straight-line basis over their estimated useful lives or over their respective estimated useful lives in proportion to the pattern of economic benefit based on expected future discounted cash flows, as deemed appropriate.

The estimated annual amortization expense as of September 27, 2024, was as follows:

Note 4–Fair Value Measurements

The accounting standard for fair value measurements establishes a three-level fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: observable inputs such as quoted prices in active markets (Level 1); inputs other than quoted prices in active markets that are observable, either directly or indirectly, or quoted prices that are not active (Level 2); and unobservable inputs in which there is little or no market data (e.g., discounted cash flow and other similar pricing models), which requires us to develop our own market participant assumptions used in pricing the asset or liability (Level 3).

The financial instruments measured at fair value on a recurring basis primarily consisted of the following:


	September 27, 2024				December 29, 2023
	Carrying value		Fair value		Carrying value		Fair value
	(in millions)
Financial assets:
Derivatives	$	4	$	4	$	11	$	11

As of September 27, 2024, and December 29, 2023, our derivatives primarily consisted of the cash flow interest rate swaps on $500 million of the variable rate senior unsecured term loan (see "Note 5–Derivative Instruments"). The fair value of the cash flow interest rate swaps is determined based on observed values for underlying interest rates on the one-month Secured Overnight Financing Rate ("SOFR") rate (Level 2 inputs).

The carrying amounts of our financial instruments, other than derivatives, which include cash equivalents, accounts receivable, accounts payable and accrued expenses, are reasonable estimates of their related fair values.

As of September 27, 2024, and December 29, 2023, the fair value of debt was $4.6 billion for both periods, and the carrying amount was $4.7 billion for both periods (see "Note 6–Debt"). The fair value of long-term debt is determined based on current interest rates available for debt with terms and maturities similar to our existing debt arrangements and our credit rating (Level 2 inputs).

During the three months ended September 29, 2023, we recorded impairment charges of SES' goodwill (see "Note 3–Goodwill and Intangible Assets"). The fair values of the assets and liabilities of the SES reporting unit were determined using a blended approach, including discounted cash flow models and market earnings multiples. The market approach estimates fair value based on profitability and valuation metrics for peer companies and applies a multiple to the reporting unit's operating performance. The income approach estimates fair value by discounting the reporting unit's estimated future cash flows using a weighted-average cost of capital reflecting current market conditions as well as the risk profile of the reporting unit. Future cash flows are based on estimates of economic and market assumptions made using the best judgment of management, including growth rates in revenue and margins, and future changes in tax rates and cash expenditures. Other significant assumptions and estimates include estimates of future capital expenditures, terminal value growth rates, and changes in future working capital requirements. The fair value of the SES reporting unit was determined using Level 3 inputs.

Note 5–Derivative Instruments

We manage our risk to changes in interest rates through the use of derivative instruments. We do not hold derivative instruments for trading or speculative purposes. For variable rate borrowings, we use fixed interest rate swaps, effectively converting a portion of the variable interest rate payments to fixed interest rate payments. These swaps are designated as cash flow hedges.

The fair value of the interest rate swaps was as follows:

Cash flow interest rate swaps

Other current assets(1)

(1) As of December 29, 2023, the cash flow interest rate swaps were reported in the "other long-term assets" on the condensed consolidated balance sheet.

The cash flows associated with the interest rate swaps are classified as operating activities in the condensed consolidated statements of cash flows.

Cash Flow Hedges

We have interest rate swap agreements to hedge the cash flows of $500 million of the variable rate senior unsecured term loan (the "Variable Rate Loan"). These interest rate swap agreements have a maturity date of August 2025 and a fixed interest rate of 2.96%. The objective of these instruments is to reduce variability in the forecasted interest payments of the Variable Rate Loan. Under the terms of the interest rate swap agreements, we will receive monthly variable interest payments based on the one-month SOFR and will pay interest at a fixed rate.

The interest rate swap transactions are accounted for as cash flow hedges. The gain/loss on the swaps is reported as a component of other comprehensive (loss) income and is reclassified into earnings when the interest payments on the underlying hedged items impact earnings. A qualitative assessment of hedge effectiveness is performed on a quarterly basis, unless facts and circumstances indicate the hedge may no longer be highly effective.

The effect of the cash flow hedges on other comprehensive (loss) income and earnings for the periods presented was as follows:


	Three Months Ended				Nine Months Ended
	September 27, 2024		September 29, 2023		September 27, 2024		September 29, 2023

Amount reclassified from accumulated other comprehensive loss to interest expense, net	$	(3)	$	(3)	$	(9)	$	(12)

We expect to reclassify net gains of $3 million from accumulated other comprehensive loss into earnings during the next 12 months.

Term Loans and Revolving Credit Facility

On March 10, 2023 (the “Closing Date”), we entered into a Credit Agreement (the “Credit Agreement”) with certain financial institutions, which provided for a senior unsecured term loan facility in an aggregate principal amount of $1.0 billion (the “Term Loan Facility”) and a $1.0 billion senior unsecured revolving facility (the “Revolving Facility” and, together with the Term Loan Facility, the “Credit Facilities”). The Credit Facilities will mature in March 2028. The Revolving Facility is subject to an annual commitment fee rate of 0.125% on the unused credit availability and permits two additional one-year extensions subject to lender consent. As of September 27, 2024, and December 29, 2023, there were no borrowings outstanding under the Revolving Facility.

The proceeds of the Term Loan Facility and cash on hand on the Closing Date were used to repay in full all indebtedness, terminate all commitments and discharge all guarantees existing in connection with a predecessor $1.9 billion senior unsecured term loan facility and a $750 million senior unsecured revolving facility.

Borrowings under the Credit Agreement bear interest at a rate determined, at our option, based on either an alternate base rate or a Term SOFR rate with a 0.10% per annum Term SOFR adjustment, plus, in each case, an applicable margin that varies depending on our credit rating. The applicable margin range for Term SOFR-denominated borrowings is from 1.00% to 1.50%. Based on our current ratings, the applicable margin for Term SOFR-denominated borrowings is 1.25%. Principal payments are made quarterly on the Term Loan Facility beginning in March 2025, with the majority of the principal due at maturity. Interest on the Term Loan Facility for Term SOFR-denominated borrowings is payable on a periodic basis, which must be at least quarterly.

Senior Notes

In fiscal 2023, we issued and sold $750 million aggregate principal amount of fixed-rate senior notes (the “Notes”) maturing in March 2033. The Notes are senior unsecured obligations issued by Leidos, Inc. and guaranteed by Leidos Holdings, Inc. The annual interest rate for the Notes is 5.75% and is payable on a semi-annual basis. In connection with the issuance of the Notes, $11 million of debt issuance costs and discount were recognized, which were recorded as an offset against the carrying value of debt.

Commercial Paper

We have a commercial paper program in which the Company may issue short-term unsecured commercial paper notes ("Commercial Paper Notes") not to exceed $1.0 billion. The proceeds will be used for general corporate purposes, including working capital, capital expenditures, acquisitions and share repurchases.

The Commercial Paper Notes are issued in minimum denominations of $0.25 million and have maturities of up to 397 days from the date of issuance. The Commercial Paper Notes either bear a stated or floating interest rate, if interest bearing, or will be sold at a discount from the face amount. As of September 27, 2024, and December 29, 2023, we did not have any Commercial Paper Notes outstanding.

Covenants

The Credit Facilities, Commercial Paper Notes and senior unsecured notes are fully and unconditionally guaranteed and contain certain customary restrictive covenants, including among other things, restrictions on our ability to create liens and enter into sale and leaseback transactions under certain circumstances.

The financial covenants in the Credit Agreement require that we maintain, as of the last day of each fiscal quarter, a ratio of adjusted consolidated total debt to consolidated EBITDA of not more than 3.75 to 1.00, subject to increases to 4.50 to 1.00 for four fiscal quarters following a material acquisition, and a ratio of EBITDA to consolidated interest expense of not less than 3.50 to 1.00.

We were in compliance with all covenants as of September 27, 2024.

Anti-dilutive stock-based awards are excluded from the weighted average number of shares outstanding used to compute diluted EPS. The total outstanding stock options and vesting stock awards that were anti-dilutive were less than 0.5 million for both the three and nine months ended September 27, 2024, and 2 million for both the three and nine months ended September 29, 2023.

During the three and nine months ended September 27, 2024, we made open market repurchases of our common stock for an aggregate purchase price of $200 million and $450 million, respectively, and $25 million during the nine months ended September 29, 2023. There were no share repurchases for the three months ended September 29, 2023. All shares repurchased were immediately retired.

Note 9–Income Taxes

For the three months ended September 27, 2024, the effective tax rate was 23.0% compared to (2.1)% for the three months ended September 29, 2023. The increase to the effective tax rate was primarily due to the tax impacts from non-deductible goodwill impairments for the three months ended September 29, 2023, and an increase in unrecognized tax benefits for the three months ended September 27, 2024.

For the nine months ended September 27, 2024, the effective tax rate was 23.3% compared to 123.7% for the nine months ended September 29, 2023. The decrease to the effective tax rate was primarily due to the tax impacts from non-deductible goodwill impairments for the nine months ended September 29, 2023, partially offset by a reduced benefit in federal research tax credits for the nine months ended September 27, 2024.

Note 10–Business Segments

Our operations and reportable segments are organized around the customers and markets we serve. We define our reportable segments based on the way the CODM, currently our Chief Executive Officer, manages operations for the purposes of allocating resources and assessing performance.

Effective the first day of fiscal 2024, we realigned our business to report into six operating segments, which are aggregated into four reportable segments in accordance with the criteria established under ASC 280: National Security & Digital, Health & Civil, Commercial & International and Defense Systems. Our reportable segments are focused on specific, defined capability sets that we bring to our customers. Additionally, we separately present the unallocable costs associated with corporate functions as Corporate. As a result of this change, prior year segment results have been recast to reflect the current reportable segment structure.

National Security & Digital provides technology enabled services and mission software capabilities for defense and intelligence customers in the areas of cyber, logistics, security operations and decision analytics, as well as IT operations and digital transformation programs across all U.S. federal government customers. Our advanced capabilities include the delivery of technology-enabled services, mission software capabilities and IT modernization services. Our capabilities allow us to provide innovative technology solutions in the following categories: software development, engineering & design, modeling & simulation, analytics, cyber security, intelligence analysis, linguistics and mission operations.

Health & Civil provides services and solutions to federal and commercial customers in the areas of public health, care coordination, life and environmental sciences and transportation. We are dedicated to delivering effective and affordable solutions that are responsible for the health and well-being of people, including service members and veterans. Our core capabilities include health information management services, managed health services, systems and infrastructure modernization, and life sciences research and development. We help customers achieve their missions and take on the connected world with data-driven insights, improved efficiencies and technological advantages.

The income statement performance measures used to evaluate segment performance are revenues and operating income (loss). As a result, "Interest expense, net," "Other income (expense), net" and "Income tax expense" as reported in the condensed consolidated statements of operations are not allocated to our segments. Under U.S. Government Cost Accounting Standards, indirect costs including depreciation expense are collected in indirect cost pools, which are then collectively allocated to the reportable segments based on a representative causal or beneficial relationship of the costs in the pool to the costs in the base. As such, depreciation expense is not separately disclosed on the condensed consolidated statements of operations.

Asset information by segment is not a key measure of performance used by the CODM.

Note 11–Commitments and Contingencies

Legal Proceedings

We are involved in various claims and lawsuits arising in the normal conduct of our business, none of which, in the opinion of management, based upon current information, will likely have a material adverse effect on our financial position, results of operations or cash flows.

Contingencies

Government Investigations and Reviews

We are routinely subject to investigations and reviews relating to compliance with various laws and regulations with respect to our role as a contractor to federal, state and local government customers and in connection with performing services in countries outside of the United States. Adverse findings could have a material effect on our business, financial position, results of operations and cash flows due to our reliance on government contracts.

Defense Contract Audit Agency

As of September 27, 2024, active indirect cost audits by the Defense Contract Audit Agency remain open for fiscal 2022 and subsequent fiscal years. Although we have recorded contract revenues based upon an estimate of costs that we believe will be approved upon final audit or review, we cannot predict the outcome of any ongoing or future audits or reviews and adjustments, and if future adjustments exceed estimates, our profitability may be adversely affected. As of September 27, 2024, we believe we have adequately reserved for potential adjustments from audits or reviews of contract costs.

Other Government Investigations and Reviews

Through its internal processes, the Company discovered, in late 2021, activities by its employees, third party representatives and subcontractors, raising concerns related to a portion of our business that conducts international operations. The Company is conducting an internal investigation, overseen by an independent committee of the Board of Directors, with the assistance of external legal counsel, to determine whether the identified conduct may have violated the Company’s Code of Conduct and potentially applicable laws, including the U.S. Foreign Corrupt Practices Act ("FCPA"). The Company has voluntarily self-reported this investigation to the Department of Justice and the Securities and Exchange Commission and is cooperating with both agencies. Because the investigation is ongoing, the Company cannot anticipate the timing, outcome or possible impact of the investigation, although violations of the FCPA and other applicable laws may result in criminal and civil sanctions, including monetary penalties, and reputational damage. In September 2022, the Company received a Federal Grand Jury Subpoena related to the criminal investigation by the U.S. Attorney’s Office for the Southern District of California, in conjunction with the U.S. Department of Justice’s Fraud Division. The subpoena requests documents relating to the conduct that is the subject of the Company’s internal investigation. The Company has responded to the subpoena. In February 2023, a former employee of the Company who was terminated at the outset of the investigation was indicted on wire fraud and other charges by a Federal Grand Jury in the U.S. District Court in the Southern District of California. These charges were later dismissed as a result of the death of the former employee.

In August 2022, the Company received a Federal Grand Jury Subpoena in connection with a criminal investigation being conducted by the U.S. Department of Justice Antitrust Division. The subpoena requests that the Company produce a broad range of documents related to three U.S. Government procurements associated with the Company’s Intelligence Group in 2021 and 2022. We are fully cooperating with the investigation, and we are conducting our own internal investigation with the assistance of outside counsel. It is not possible at this time to determine whether we will incur, or to reasonably estimate the amount of, any fines, penalties, or further liabilities in connection with the investigation pursuant to which the subpoena was issued.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion and analysis of Leidos Holdings, Inc.'s ("Leidos") financial condition, results of operations, and quantitative and qualitative discussion about business environment and trends should be read in conjunction with Leidos' condensed consolidated financial statements and related notes.

The following discussion contains forward-looking statements, including statements regarding our intent, belief or current expectations with respect to, among other things, trends affecting our financial condition or results of operations, backlog, our industry, the impact of our merger and acquisition activity, government budgets and spending, our business contingency plans, interest rates and uncertainties in tax due to new tax legislation or other regulatory developments. In some cases, forward-looking statements can be identified by words such as “will,” “expect,” “estimate,” “plan,” “potential,” “continue” or similar expressions. Such statements are not guarantees of future performance and involve risks and uncertainties and actual results may differ materially from those in the forward-looking statements as a result of various factors. Some of these factors include, but are not limited to, the risk factors set forth in our Annual Report on Form 10-K, as updated by the risk factor in this report under Part II, Item 1A. "Risk Factors" and as may be further updated in subsequent filings with the U.S. Securities and Exchange Commission. Due to such uncertainties and risks, you are cautioned not to place undue reliance on such forward-looking statements, which speak only as of the date hereof. We do not undertake any obligation to update these factors or to publicly announce the results of any changes to our forward-looking statements due to future events or developments.

Unless indicated otherwise, references in this report to "we," "us" and "our" refer collectively to Leidos and its consolidated subsidiaries.

Overview

Leidos, a member of the Fortune 500®, is a dynamic innovation company that is at the forefront of addressing the world’s most challenging issues in national security and health sectors. With a global workforce of approximately 48,000, Leidos is committed to developing smarter technology solutions, particularly for customers in highly regulated industries. We bring domain-specific capability and cross-market 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, National Aeronautics and Space Administration and many other U.S. civilian, state and local government agencies, foreign government agencies and commercial businesses.

Beginning in fiscal 2024, we realigned our business and operate in four reportable segments that are focused on specific, defined capability sets we bring to our customers. As a result of this change, prior year segment results and disclosures have been recast to reflect the current reportable segment structure. We now operate in the following reportable segments: National Security & Digital, Health & Civil, Commercial & International and Defense Systems. We also separately present the unallocable costs associated with corporate functions as Corporate (see "Note 10–Business Segments").

Business Environment and Trends

U.S. Government Markets

During the three and nine months ended September 27, 2024, we generated approximately 87% of total revenues from contracts with the U.S. government, as compared to 87% and 86% for the three and nine months ended September 29, 2023, respectively. Accordingly, our business performance is affected by the overall level of U.S. government spending, especially on national security, homeland security and intelligence, and the alignment of our service and product offerings and capabilities with current and future budget priorities of the U.S. government.

On September 26, 2024, Congress avoided a federal government shutdown by passing a continuing resolution that provides government funding through December 20, 2024. The continuing resolution gives lawmakers additional time after the November elections to consider the 12 appropriations bills for government fiscal year 2025, emergency supplemental funding for the recent hurricanes and wildfires, and organize new leadership of the House of Representatives and Senate. Failure to pass the appropriation bills or another continuing resolution by December 20, 2024, will result in a partial or complete federal government shutdown.

LEIDOS HOLDINGS, INC.

International Markets

Sales to customers in international markets represented approximately 8% of total revenues for both the three and nine months ended September 27, 2024, as compared to 9% for both the three and nine months ended September 29, 2023. Our international customers include foreign governments and their agencies. Our international business increases our exposure to international markets and the associated international regulatory and geopolitical risks.

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

The increase in operating loss for the nine months ended September 27, 2024, as compared to the nine months ended September 29, 2023, was primarily attributable to increased general and administrative expenses.

Non-Operating Expense, net

Non-operating expense, net for the three months ended September 27, 2024, was $46 million as compared to $52 million for the three months ended September 29, 2023. The decrease was primarily driven by increased interest income due to higher cash balances.

Non-operating expense, net for the nine months ended September 27, 2024, was $142 million as compared to $167 million for the nine months ended September 29, 2023. The decrease was primarily driven by increased interest income due to higher cash balances, lower interest expense driven by commercial paper borrowings in the prior year and favorable exchange rate movements.

Provision for Income Taxes

For the three months ended September 27, 2024, our effective tax rate was 23.0% compared to (2.1)% for the three months ended September 29, 2023. The increase to the effective tax rate was primarily due to the tax impacts from non-deductible goodwill impairments for the three months ended September 29, 2023, and an increase in unrecognized tax benefits for the three months ended September 27, 2024.

For the nine months ended September 27, 2024, our effective tax rate was 23.3% compared to 123.7% for the nine months ended September 29, 2023. The decrease to the effective tax rate was primarily due to the tax impacts from non-deductible goodwill impairments for the nine months ended September 29, 2023, partially offset by a reduced benefit in federal research tax credits for the nine months ended September 27, 2024.

In December 2021, the Organization for Economic Cooperation and Development enacted model rules for a new 15% global minimum tax framework (“Pillar Two”). Many governments around the world have enacted or are in the process of enacting Pillar Two legislation. The Pillar Two legislation became effective for certain jurisdictions beginning in fiscal 2024. We will continue to evaluate the impact of the rules as additional legislation gets enacted but currently do not expect them to have a material impact.

Backlog represents the estimated amount of future revenues to be recognized under negotiated contracts, both funded and unfunded. Backlog does not include unexercised option periods and future potential task orders expected to be awarded under indefinite delivery/indefinite quantity ("IDIQ") contracts, General Services Administration 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.

Backlog estimates are subject to change and may be affected by factors including modifications of contracts and foreign currency movements.

Liquidity and Capital Resources

Overview

As of September 27, 2024, we had $1,185 million in cash and cash equivalents. We have a senior unsecured revolving credit facility which can provide up to $1 billion in additional borrowing, if required. As of September 27, 2024, and December 29, 2023, there were no borrowings outstanding under the revolving credit facility.

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 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 the three and nine months ended September 27, 2024, we made open market repurchases of our common stock for an aggregate purchase price of $200 million and $450 million, respectively, and $25 million during the nine months ended September 29, 2023.There were no share repurchases for the three months ended September 29, 2023.

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, borrowings from our commercial paper program and, if needed, sales of accounts receivable and borrowings from our revolving credit facility.

Summary of Cash Flows

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


	Three Months Ended				Nine Months Ended
	September 27, 2024		September 29, 2023		September 27, 2024		September 29, 2023
	(in millions)
Net cash provided by operating activities	$	656	$	795	$	1,093	$	861
Net cash used in investing activities	(23)		(52)		(56)		(135)
Net cash used in financing activities	(257)		(249)		(644)		(470)

Net cash provided by operating activities decreased $139 million during the three months ended September 27, 2024, when compared to the prior year quarter. The decrease was primarily due to unfavorable changes in working capital, partially offset by higher earnings and the timing of payroll and employee benefit accruals.

Net cash provided by operating activities increased $232 million during the nine months ended September 27, 2024, when compared to the prior year. The increase was primarily due to higher earnings and lower tax payments of $49 million primarily due to payments made in the prior year for the TCJA provision and payroll taxes related to the CARES act.

Net cash used in investing activities decreased $29 million and $79 million during the three and nine months ended September 27, 2024, respectively, when compared to the prior year. The decreases were primarily due to lower capital expenditures of $27 million and $66 million for the three and nine months ended September 27, 2024, respectively.

Net cash used in financing activities increased $8 million for the three months ended September 27, 2024, when compared to the prior year quarter, primarily due to a $202 million increase in stock repurchases, partially offset by $200 million in commercial paper net proceeds received in the prior year.

Net cash used in financing activities increased $174 million for the nine months ended September 27, 2024, when compared to the prior year. The increase was primarily due to a $425 million increase in stock repurchases, a $31 million increase in shares withheld for tax obligations, partially offset by a decrease of $291 million in net payments made on debt activities.

Off-Balance Sheet Arrangements

We have outstanding performance guarantees and cross-indemnity agreements in connection with certain aspects of our business. We also have letters of credit outstanding principally related to performance guarantees on contracts and surety bonds outstanding principally related to performance and subcontractor payment bonds as described in "Note 11–Commitments and Contingencies" of the notes to the condensed consolidated financial statements contained within this Quarterly Report on Form 10-Q. 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 expenditures or capital resources, operations or financial condition.

Income Taxes	Note 9–Income Taxes For the three months ended September 27, 2024, the effective tax rate was 23.0% compared to (2.1)% for the three months ended September 29, 2023. The increase to the effective tax rate was primarily due to the tax impacts from non-deductible goodwill impairments for the three months ended September 29, 2023, and an increase in unrecognized tax benefits for the three months ended September 27, 2024. For the nine months ended September 27, 2024, the effective tax rate was 23.3% compared to 123.7% for the nine months ended September 29, 2023. The decrease to the effective tax rate was primarily due to the tax impacts from non-deductible goodwill impairments for the nine months ended September 29, 2023, partially offset by a reduced benefit in federal research tax credits for the nine months ended September 27, 2024.

Accounting Policies [Abstract]
Consolidation	We have a controlling interest in Mission Support Alliance, LLC ("MSA"), a joint venture with Centerra Group, LLC. We also have a controlling interest in Hanford Mission Integration Solutions, LLC ("HMIS"), the legal entity for the follow-on contract to MSA's contract and a joint venture with Centerra Group, LLC and Parsons Government Services, Inc. The financial results for MSA and HMIS are consolidated into our unaudited condensed consolidated financial statements. The unaudited condensed consolidated financial statements also include the balances of all voting interest entities in which Leidos has a controlling voting interest ("subsidiaries") and a variable interest entity ("VIE") in which Leidos is the primary beneficiary. The consolidated balances of the VIE are not material to the unaudited condensed consolidated financial statements for the periods presented. Intercompany accounts and transactions between consolidated companies have been eliminated in consolidation.
Basis of Accounting	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the rules of the U.S. Securities and Exchange Commission and accounting principles generally accepted in the United States of America ("GAAP"). Certain disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules.
Estimates	The preparation of financial statements in conformity 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, including those relating to estimated profitability of long-term contracts, indirect billing rates, allowances for doubtful accounts, inventories, right-of-use assets and lease liabilities, fair value and impairment of intangible assets and goodwill, income taxes, stock-based compensation expense and contingencies. These estimates have been prepared by management on the basis of the most current and best available information; however, actual results could differ materially from those estimates. Certain amounts in the prior year financial statements have been reclassified to conform to the current year presentation. We combined "Deferred tax liabilities" into "Other long-term liabilities" on the condensed consolidated balance sheets.
Accounting Standards Updates Issued But Not Yet Adopted	Accounting Standards Updates Issued But Not Yet Adopted ASU 2023-07 Segment Reporting In November 2023, the FASB issued ASU 2023-07, to improve reportable segment disclosure requirements. This update requires companies to disclose significant segment expense categories that are regularly provided to the chief operating decision maker ("CODM") on an interim and annual basis and expands disclosure requirements for interim reporting. Companies must also disclose how segment measures of profit or loss are used by the CODM. The amendments in this update are effective for public entities for annual periods beginning after December 15, 2023, and interim periods beginning after December 15, 2024. The amendments should be adopted on a retrospective basis and early adoption is permitted. We will adopt these amendments for annual disclosures in fiscal 2024 and interim disclosures in fiscal 2025. ASU 2023-09 Income Taxes In December 2023, the FASB issued ASU 2023-09, to enhance the transparency and usefulness of income tax disclosures. The update requires enhancements to the annual rate reconciliation, including disclosure of specific categories and additional information for reconciling items meeting a quantitative threshold. The update also requires disclosure of income taxes paid disaggregated by federal, state and foreign taxes, and individual jurisdictions meeting a quantitative threshold. The amendments in this update are effective for public business entities for annual periods beginning after December 15, 2024, and may be adopted on a prospective or retrospective basis. Early adoption is permitted. We are currently evaluating the impacts of this update and plan to adopt these amendments using the prospective approach for annual disclosures in fiscal 2025.
Changes in Estimates on Contracts	Changes in Estimates on Contracts Changes in estimates related to contracts accounted for using the cost-to-cost method of accounting are recognized in the period in which such changes are made for the inception-to-date effect of the changes, with the exception of contracts acquired through a business combination, where the adjustment is made for the period commencing from the date of acquisition. The impact on diluted earnings per share ("EPS") attributable to Leidos common stockholders is calculated using the statutory tax rate. The changes primarily relate to revisions of variable consideration including award and incentive fees, and revisions to estimates at completion resulting from changes in contract scope, mitigation of contract risks or true-ups of contract estimates at the end of contract performance.
Cash and Cash Equivalents	Cash and Cash Equivalents Our cash equivalents are primarily comprised of investments in several large institutional money market accounts, with original maturity of three months or less.
Restricted Cash	Restricted Cash We have restricted cash balances, primarily representing advances from customers that are restricted for use on certain expenditures related to that customer's contract. Restricted cash balances are included as "Other current assets" in the condensed consolidated balance sheets.
