RESTON, Va., February 11, 2025 – Leidos Holdings, Inc. (NYSE: LDOS) today reported financial results for the fourth quarter and fiscal year 2024, highlighted by double-digit earnings growth, accelerating revenue growth, and excellent business development results. In addition, Leidos established guidance for 2025 that forecasts continued growth in revenues, non-GAAP diluted earnings per share, and cash flows provided by operating activities.

"2024 was a fantastic year for Leidos, as we delivered robust results at or above the high end of our guidance range across all metrics," said Leidos Chief Executive Officer Tom Bell. "The fourth quarter was especially strong in revenue growth and business development, driven by our focus on the enduring, mission critical needs of our customers. In addition, our 2024 performance propelled us beyond the three-year targets established at our 2021 Investor Day."

"Our outlook for the future remains decidedly positive, as we have a clearly defined strategy and technology-enabled team that is poised to navigate this dynamic environment from a position of strength," Bell said.

Net bookings totaled $7.6 billion in the fourth quarter and $23.4 billion for fiscal year 2024, representing book-to-bill ratios of 1.7 and 1.4, respectively.

uVeterans Benefits Administration (VBA) Medical Disability Examinations (MDE) Regions 1-4 Follow-On. The VBA MDE Office awarded Leidos an indefinite delivery, indefinite quantity (IDIQ), firm-fixed price contract with a period of performance of one year and one optional year.

uIndirect Fires Protection Capability (IFPC) Increment 2 Program. Leidos was awarded a five-year, $4.1 billion IDIQ contract by the U.S. Army’s Program Executive Office Missile and Space for the IFPC Increment 2 Program.

For information regarding adjusted EBITDA margin and non-GAAP diluted EPS, see the related explanations and reconciliations to GAAP measures included elsewhere in this release.

Leidos does not provide a reconciliation of forward-looking adjusted EBITDA margins or non-GAAP diluted EPS to net income margin or diluted EPS, due to the inherent difficulty in forecasting and quantifying certain amounts that are necessary for such reconciliation. Because certain deductions for non-GAAP exclusions used to calculate projected net income may vary significantly based on actual events, Leidos is not able to forecast on a GAAP basis with reasonable certainty all deductions needed in order to provide a GAAP calculation of projected net income margin, diluted EPS or net income attributable to Leidos shareholders at this time. The amounts of these deductions may be material and, therefore, could result in projected net income margin, net income attributable to Leidos shareholders and diluted EPS being materially less than projected adjusted EBITDA margins and non-GAAP diluted EPS.

National Security & Digital

National Security & Digital revenues were $1.89 billion for the quarter and $7.37 billion for the year, up 5% and 2% over the comparable 2023 periods, respectively. Revenue growth in the quarter and the year was primarily from higher volumes on digital modernization programs as well as increased activity on the Sentinel contract.

National Security & Digital operating income margin for the quarter was 9.2%, compared to10.3% in the prior year quarter. On a non-GAAP basis, operating margin for the quarter was 9.7%, compared to 11.0% in the prior year quarter. The decrease in segment profitability derives from immaterial changes across multiple fixed-price programs. National Security & Digital operating income margin for fiscal year 2024 was 9.8%, compared to 9.3% in the prior year. On a non-GAAP basis, operating margin for the year was 10.2%, compared to 10.0% in the prior year. The increase in segment profitability for the year was primarily attributable to improved program execution and increased volumes and efficiencies on certain fixed price programs.

Health & Civil

Health & Civil revenues were $1.33 billion for the quarter and $5.02 billion for the year, up 16% and 18% over the comparable 2023 periods, respectively. Health & Civil operating income margin for the quarter was 21.0%, compared to 14.2% in the prior year quarter. On a non-GAAP basis, operating margin for the quarter was 21.6%, compared to 15.1% in the prior year quarter. Health & Civil operating income margin for fiscal year 2024 was 21.8%, compared to 13.5% in the prior year. On a non-GAAP basis, operating margin for the year was 22.5%, compared to 14.5% in the prior year. The increase in revenues and segment profitability for the quarter and the year was driven by increased volumes and case complexity within the managed health services business as well as net write-ups on certain programs.

UNAUDITED SEGMENT OPERATING RESULTS [CONTINUED]

Commercial & International

Commercial & International revenues were $604 million for the quarter and $2.25 billion for the year, up 12% and 6% over the comparable 2023 periods. The primary drivers for revenue growth in the quarter and year were increased deliveries of security products and higher volumes within commercial energy, Australian IT and airborne solutions businesses.

Commercial & International operating income margin for the quarter was 6.6%, compared to 7.2% in the prior year quarter. On a non-GAAP basis, operating margin for the quarter was 7.9%, compared to 8.7% in the prior year quarter. The decrease in segment profitability is attributable to product business mix within the security products business and increased investments in growth. Commercial & International operating income margin for fiscal year 2024 was 4.6%, compared to (26.3)% in the prior year, which included pre-tax impairment and restructuring charges associated with the Security Enterprise Solutions (SES) reporting unit. On a non-GAAP basis, operating margin for the year was 6.4% compared to 7.8% in the prior year.

The decrease in segment profitability for the year is primarily driven by the impact of rebaselining certain contracts within the United Kingdom (UK) business that occurred in the second quarter of fiscal year 2024.

Defense Systems

Defense System revenues were $539 million for the quarter and $2.03 billion for the year, up 7% and 8% over the comparable 2023 periods, respectively. The increase in revenues for the quarter and year were primarily driven by increased scope and new business awards. Defense Systems operating income margin for the quarter was 0.4%, compared to 3.6% in the prior year quarter. On a non-GAAP basis, operating margin for the quarter was 3.5%, down from 7.7% in the prior year quarter. Defense Systems operating income margin for fiscal year 2024 was 4.6%, compared to 3.5% in the prior year. On a non-GAAP basis, operating margin for the year was 7.9%, down from 8.3% in fiscal year 2023. The decrease in segment profitability for the quarter and year is driven by a $21M write-down of an asset within the airborne surveillance business.

UNAUDITED BACKLOG BY REPORTABLE SEGMENT

Backlog represents the estimated amount of future revenues to be recognized under negotiated contracts. Backlog value is based on management’s estimates about volume of services, availability of customer funding and other factors, and excludes contracts that are under protest. Estimated backlog comprises both funded and negotiated unfunded backlog. Backlog estimates are subject to change and may be affected by several factors including modifications of contracts, non-exercise of options and foreign currency movements.

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 Leidos is obligated to perform, less revenue previously recognized on the contracts.

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, General Services Administration Schedule or other master agreement contract vehicles, with the exception of certain IDIQ contracts where task orders are not competitively awarded or 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.

Leidos Holdings, Inc. Exhibit 99.1

LEIDOS HOLDINGS, INC.

UNAUDITED NON-GAAP FINANCIAL MEASURES

Leidos uses and refers to organic revenues, non-GAAP operating income, non-GAAP operating margin, adjusted EBITDA, adjusted EBITDA margin, non-GAAP diluted EPS, free cash flow and free cash flow conversion, which are not measures of financial performance under generally accepted accounting principles in the U.S. and, accordingly, these measures should not be considered in isolation or as a substitute for the comparable GAAP measures and should be read in conjunction with Leidos's consolidated financial statements prepared in accordance with GAAP.

Management believes that these non-GAAP measures provide another measure of the results of operations and financial condition, including its ability to comply with financial covenants. These non-GAAP measures are frequently used by financial analysts covering Leidos and its peers. The computation of non-GAAP measures may not be comparable to similarly titled measures reported by other companies, thus limiting their use for comparability.

Organic revenues captures the revenue that is inherent in the underlying business excluding the impact of acquisitions and divestitures made within the prior year; it is computed as current revenues excluding revenues from acquisitions within the last 12 months and divestitures within the current and year-ago periods.

Non-GAAP operating income is computed by excluding the following discrete items from operating income:

uAcquisition, integration and restructuring costs – Represents acquisition, integration, lease termination, severance and retention costs and asset markdowns related to acquisitions and restructuring activities.

uAmortization of acquired intangible assets – Represents the amortization of the fair value of the acquired intangible assets.

uGain on sale of intangible assets – Represents the gain on sale of intellectual property not used in operations.

uAsset impairment charges – Represents impairments of long-lived intangible assets, right-of-use assets, and other assets related to our facility rationalization effort.

uGoodwill impairment charges – Represents impairments of goodwill due to changes in actual performance against performance projected when the goodwill was acquired.

Non-GAAP operating margin is computed by dividing non-GAAP operating income by revenues.

Adjusted EBITDA is computed by excluding the following items from income before income taxes: (i) discrete items as identified above; (ii) interest expense; (iii) interest income; (iv) depreciation expense; and (v) amortization of internally developed intangible assets.

Adjusted EBITDA margin is computed by dividing adjusted EBITDA by revenues.

Non-GAAP net income is computed by excluding the discrete items listed under non-GAAP operating income and their related tax impacts.

Non-GAAP diluted EPS is computed by dividing net income attributable to Leidos common stockholders, adjusted for the discrete items as identified above and the related tax impacts, by the diluted weighted average number of common shares outstanding.

Non-GAAP free cash flow is computed by deducting expenditures for property, equipment and software from net cash provided by operating activities.

Non-GAAP free cash flow conversion is computed by dividing free cash flow by non-GAAP net income attributable to Leidos common stockholders; operating cash flow conversion is computed by dividing net cash provided by operating activities by net income attributable to Leidos shareholders.
