Leidos Delivers Strong Third Quarter and Enhances Full-Year Guidance

Open on SEC ↗

u Adjusted EBITDA (non-GAAP) of $644 million and Adjusted EBITDA margin (non- GAAP) of 13.9%

u Cash Flows from Operations of $523 million; Non-GAAP Free Cash Flow of $476 million

RESTON, Va., November 3, 2026 – Leidos Holdings, Inc. (NYSE: LDOS) today reported financial results for the third quarter of fiscal year 2026, highlighted by robust revenue growth and free cash flow generation.

“Leidos delivered another quarter of strong financial performance, allowing us to enhance our 2026 guidance for the third consecutive quarter,” said Chief Executive Officer Tom Bell. “Our sustained momentum reflects the strength of our focused team, united behind our NorthStar 2030 strategy and committed to delivering on our customers’ most critical missions. Looking ahead, we’ll continue to execute our strategy with confidence, invest in differentiated capabilities, and deploy capital strategically to accelerate growth and create enduring value.”

(in millions, except margin and per Three Months October 2, October 3, share data) Ended 2026 2025 ────────────────────────────────────────────────────────────────────────────── Revenues $ 4,630 $ 4,469 Net income $ 413 $ 369 Net income 8.9 % 8.3 % margin Diluted earnings per $ 3.28 $ 2.82 share (EPS) Non-GAAP Measures*: Adjusted $ 644 $ 616 EBITDA Adjusted EBITDA 13.9 % 13.8 % margin Non-GAAP $ 3.62 $ 3.05 diluted EPS * Non-GAAP financial measures should be considered in addition to, but not as a substitute for, the information provided in accordance with GAAP. Management believes that these non-GAAP measures provide another representat… of Leidos' results of operations and financial condition, including its ability to comply with financial covenants. See Non-GAAP Financial Measures at the end of this press release for more information and a reconciliat… of our selected reported results to these non-GAAP measures.

Revenues for the quarter were $4.63 billion, up 4% compared to the third quarter of 2025. Revenue grew year-over-year due to increased customer demand for defense tech products, air traffic management solutions, and intelligence mission support as well as the acquisition of ENTRUST Solutions, which offset declines in some managed health and federal civilian IT programs.

For the third quarter, net income was $413 million, or $3.28 per diluted share. Net income and diluted EPS were up 12% and 16%, respectively, year-over-year; net income margin was 8.9% compared to 8.3% in the third quarter of 2025. Net income and diluted EPS for the quarter reflect $12 million in costs associated with recent strategic corporate transactions. Adjusting for these and certain other items, non-GAAP net income increased 14% year-over-year, to $455 million for the third quarter, and non-GAAP diluted EPS increased 19% to $3.62. GAAP and non-GAAP earnings measures reflect a lower effective tax rate, primarily due to an increase in the federal research tax credit and a decrease in unrecognized tax benefits.

In addition, adjusted EBITDA was $644 million for the third quarter, up 5% year- over-year. Adjusted EBITDA margin of 13.9% increased from 13.8% in the third quarter of 2025. Profitability in the quarter was driven by improved program performance and disciplined cost management across the portfolio.

Net cash provided by operating activities for the quarter was $523 million for an operating cash flow conversion ratio of 128%. After adjusting for property, equipment, and software payments, quarterly free cash was $476 million for a free cash flow conversion ratio of 105%.

For the quarter, Leidos used $48 million in investing activities, including $47 million in property, equipment and software payments. Leidos used $549 million in financing activities, consisting primarily of $556 million returned to shareholders, including $504 million in share repurchases and $52 million as part of a regular quarterly cash dividend program. As of October 2, 2026, Leidos had $630 million in cash and cash equivalents and $6.0 billion of debt.

On October 30, 2026, the Leidos Board of Directors declared a cash dividend of $0.45 per share, which represents an increase of 4.7% over the prior quarter's dividend amount. The dividend will be payable on December 31, 2026, to stockholders of record at the close of business on December 15, 2026.

Net bookings totaled $5.5 billion in the quarter, representing a book-to-bill ratio of 1.2. As a result, backlog at the end of the quarter was $49.6 billion, of which $11.1 billion was funded. Trailing-twelve-month book-to-bill of 1.1 resulted in year-over-year growth in total and funded backlog of 4% and 22%, respectively. Quarterly bookings included several key awards:

u U.S. Air Force Air Combat Command (ACC) Intelligence Directorate (A2) Intelligence, Surveillance, Reconnaissance (ISR). Leidos secured a $717 million contract to continue providing critical threat mitigation and ISR operations support for the Air Force's ACC A2. Leidos is executing at 35 global locations, delivering embedded advanced data fusion across ACC headquarters, numbered Air Forces, and wings to ensure that the joint force maintains a decisive information advantage.

u Transportation Security Administration (TSA) Security Equipment Deployment Services (SEDS). TSA awarded Leidos a $672 million contract to continue to deploy, relocate, and manage critical security screening equipment across all federalized U.S. airports and major domestic special events. This award builds upon more than a decade of Leidos supporting TSA infrastructure, leveraging their deep logistics and integration expertise to protect the nation's transportation systems and adapt swiftly to emerging security threats.

u Defense Health Agency (DHA) Military Health System (MHS) GENESIS Bridge. Leidos secured a 12-month, $318 million sole-source bridge contract to sustain and enhance MHS GENESIS, including system maintenance, cybersecurity, performance monitoring, technology updates, and end-user support. The award ensures continuity of critical operations while reinforcing Leidos' expertise in modernizing complex federal health systems and delivering technology that supports healthcare for service members and their families.

u U.S. Army Defensive Cyber Solutions Branch (DCSB) Defensive Cyber Operations (DCO) 2.0. Leidos was awarded a $301 million follow-on contract to provide 24/7/365 defensive cyber operations for the Department of War Information Network (DoDIN). To support the agency's migration toward continuous, automated outcome delivery, Leidos is deploying its UpHold Effect Agentic SOC Automation platform. The platform utilizes autonomous AI agents that dramatically compresses threat response windows and eliminates analyst alert fatigue to ensure a hardened, reliable global network capable of defending against growing and evolving threats.

u Space Development Agency (SDA) Accelerated Missile Defense Tranche 3 (AMDT3). Leidos secured a $272 million award from Sierra Space to provide infrared sensing payloads, onboard signal-processing capabilities, and mission support for the AMDT3 Tracking Layer. The payloads will fly on 18 missile-tracking satellites, which are designed to detect hypersonic and other advanced threats from Low Earth Orbit. This award expands Leidos' position in space sensing and onboard digital processing, and builds on its execution record on Tranches 0, 1, and 2.

u United Kingdom (UK) National Air Traffic Services (NATS) Flight Data Processing (FDP) Evolution. Leidos received a $170 million contract to upgrade the core flight data processing software under the UK NATS FDP Evolutions program, replacing legacy systems with a modern architecture that automatically delivers real-time flight data to air traffic controllers. This award strengthens Leidos' global position in next-generation air traffic management and reinforces its pedigree for upcoming modernization projects.

u U.S. Cyber Command (CYBERCOM) Cyberspace Operations Support Services (COSS). Leidos secured a five-year, $160 million contract to support USCYBERCOM's J3, Cyber National Mission Force, and Joint Task Force Area with planning, training, strategy, doctrine development, and campaign assessment. This award marks Leidos' first cyber operations award

with USCYBERCOM and establishes a prime foothold with a strategically important customer in a high-growth national security mission area.

u U.S. Navy Nuclear-Armed Sea-Launched Cruise Missile (SLCM-N). The Navy awarded Leidos a $155 million contract to continue to advance flight systems integration and flight vehicle subsystem development for a sea-based theater nuclear deterrent.

u Customer & Border Patrol (CBP) and Immigration & Customs Enforcement (ICE) Shared Electronic Health Record (EHR) Platform and Support Services. Leidos secured a five-year, $129 million single-award blanket purchase agreement (BPA) to implement and sustain a modern EHR system for U.S. CBP and ICE. Under the initial call order, Leidos will deploy an integrated EHR system for ICE, consolidating core healthcare capabilities, enabling secure information exchange, and improving continuity of care. Building on the company's MHS GENESIS success, the award establishes and foundation for expansion across Department of Homeland Security (DHS) components.

u U.S. Army Long-Range Persistent Surveillance—Mobile (ALPS-M) and U.S. Marine Corps Multi-Role Air Defense Radar (MRADR). The Army awarded Leidos a $95 million contract to deliver 10 prototypes of its current ALPS capability, which is being deployed globally through the U.S. Air Force's Air Base Air Defense System - Missile Defense (ABADS-MD) program. Separately, Leidos secured a $41 million contract to build 14 additional MRADR systems for the Marine Corps. Together, these awards demonstrate sustained customer demand for Leidos' family of persistent surveillance sensing technologies.

T he U.S. Special Operations Command awarded Leidos a $27 million contract for the Low-Rate Initial Production (LRIP) of the AGM-190A Havoc Spear SCM. Under this award, Leidos will deliver an initial quantity of 45 All Up Rounds for operational fielding in Air Force Special Operations Command (AFSOC). Havoc Spear has the potential to be broadly deployed across special operations and conventional military platforms for low-cost precision strike mass capability in contested environments.

On October 5, 2026, Leidos closed the Contribution and Equity Purchase Agreement with Altaris, contributing the Security Enterprise Solutions and Industrial Automation (SES) businesses to a newly formed joint venture. After adjusting for the Joint Venture and incorporating its year-to-date performance and current outlook, Leidos is adjusting its fiscal year 2026 guidance as follows:

FY26 Guidance Measure Current Prior Revenues (B) $18.00 - $18.20 $18.20 - $18.40 Adjusted EBITDA Margin Mid 13% Mid 13% Non-GAAP Diluted EPS $12.50 - $12.70 $12.20 - $12.50 Cash Flows Provided by Operating Approximately $1.90 Approximately $1.85 Activities (B)

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 margin or diluted EPS 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 at this time. The amounts of these deductions may be material and, therefore, could result in projected net income margin and diluted EPS being materially less than what may be implied by projected adjusted EBITDA margins and non-GAAP diluted EPS.

Leidos management will discuss operations and financial results in an earnings conference call beginning at 8 A.M. eastern time on November 3, 2026. A live audio broadcast of the conference call along with a supplemental presentation will be available to the public through links on the Leidos Investor Relations website (

). An archived version of the webcast will be available on the Leidos Investor Relations website until November 3, 2027.

Leidos is an industry and technology leader serving government and commercial customers with smarter, more efficient digital and mission innovations. Headquartered in Reston, Virginia, with 50,000 global employees, Leidos reported annual revenues of approximately $17.2 billion for the fiscal year ended January 2, 2026. For more information, visit

Beginning fiscal 2026, we completed a realignment of our reporting structure, which resulted in the identification of four reportable segments: Intelligence & Digital, Health, Homeland and Defense. Additionally, we separately present the unallocable costs associated with corporate functions as Corporate. We commenced operating and reporting under the new organizational structure effective the first day of fiscal 2026. As a result of this change, prior year segment results have been recast to reflect the current reportable segment structure.

Intelligence & Digital revenues grew 1% year-over-year to $1.55 billion driven by recent contract awards and higher volumes and expanded scope across key Intelligence Community programs offset by reductions in certain federal civilian IT programs. Operating income margin was 11.1% compared to 9.2% in the prior year quarter, and non-GAAP operating income margin was 11.5%, up from the prior year quarter. Profitability enhancements were driven by a mix of better program execution, including strong award fee scores and disciplined cost management across the segment.

Health revenues of $1.07 billion decreased by 12% compared to the prior year quarter. Health operating income margin for the quarter was 22.5%, compared to 26.8% in the prior year quarter, and non-GAAP operating income margin was 22.8%, compared to 27.3% in the prior year quarter. The declines in revenues and margins were driven by expected program shifts and reduced volumes on managed health services programs.

Homeland revenues of $1.02 billion increased by 32% compared to the prior year quarter. Revenue growth was driven by strong demand for air traffic management and electric power distribution engineering solutions as well as $142 million from the acquisition of ENTRUST Solutions. Operating income margin for the quarter was 7.9%, compared to 6.5% in the prior year quarter, and non-GAAP operating margin increased to 11.3% from 7.5% in the prior year quarter. Profitability enhancements reflect an increased mix of higher-margin commercial work and disciplined cost management across the segment.

Defense revenues of $992 million were up 3% compared to the prior year quarter led by increased demand for several defense technology areas including air defense, sensing, and C5ISR systems. Defense operating income margin for the quarter was 8.7%, compared to 8.2% in the prior year quarter, and non-GAAP operating margin was 9.7%, compared to 9.8% in the prior year quarter.

Backlog represents the revenues we expect to recognize under negotiated contracts and unissued task orders on sole source IDIQ contracts, to the extent we believe their execution and funding to be probable. Backlog does not include potential task orders expected to be awarded under multiple award IDIQ 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. Unfunded backlog represents all remaining value on task orders that is not funded, including options, that we expect to recognize as well as expected future task orders under sole source IDIQ contracts.

Backlog at October 2, 2026, includes amounts acquired as part of the Entrust transaction. As of March 27, 2026, the acquisition date, Entrust had $371 million of backlog that was included within the Homeland reportable segment.

Leidos uses and refers to non-GAAP operating income, non-GAAP operating margin, adjusted EBITDA, adjusted EBITDA margin, non-GAAP diluted EPS, non-GAAP free cash flow and non-GAAP 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 representation 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.

The following table presents the reconciliation of revenues to organic revenues by reportable segment and total operations:

(1) Current period acquisition revenues reflects revenues in the current as reported figures for 12 months from closing of each acquisition. Acquisition revenues for the three months ended October 2, 2026, for the Homeland segment includes Entrust (acquired March 27, 2026).

(2) Prior period divestiture revenues reflect revenues from assets subsequently divested. Divestiture revenues for the three months ended October 3, 2025, for the Homeland segment include an immaterial business not aligned to the Company's long term strategy (divested October 31, 2025).

Revenues for the quarter were $4.63 billion, up 4% compared to the third quarter
of 2025. Revenue grew year-over-year due to increased customer demand for
defense tech products, air traffic management solutions, and intelligence
mission support as well as the acquisition of ENTRUST Solutions, which offset
declines in some managed health and federal civilian IT programs.

For the third quarter, net income was $413 million, or $3.28 per diluted share.
Net income and diluted EPS were up 12% and 16%, respectively, year-over-year;
net income margin was 8.9% compared to 8.3% in the third quarter of 2025. Net
income and diluted EPS for the quarter reflect $12 million in costs associated
with recent strategic corporate transactions. Adjusting for these and certain
other items, non-GAAP net income increased 14% year-over-year, to $455 million
for the third quarter, and non-GAAP diluted EPS increased 19% to $3.62. GAAP and
non-GAAP earnings measures reflect a lower effective tax rate, primarily due to
an increase in the federal research tax credit and a decrease in unrecognized
tax benefits.

In addition, adjusted EBITDA was $644 million for the third quarter, up 5% year-
over-year. Adjusted EBITDA margin of 13.9% increased from 13.8% in the third
quarter of 2025. Profitability in the quarter was driven by improved program
performance and disciplined cost management across the portfolio.

outcome delivery, Leidos is deploying its UpHold Effect Agentic SOC Automation
platform. The platform utilizes autonomous AI agents that dramatically
compresses threat response windows and eliminates analyst alert fatigue to
ensure a hardened, reliable global network capable of defending against growing
and evolving threats.

u Space Development Agency (SDA) Accelerated Missile Defense Tranche 3 (AMDT3).
Leidos secured a $272 million award from Sierra Space to provide infrared
sensing payloads, onboard signal-processing capabilities, and mission support
for the AMDT3 Tracking Layer. The payloads will fly on 18 missile-tracking
satellites, which are designed to detect hypersonic and other advanced threats
from Low Earth Orbit. This award expands Leidos' position in space sensing and
onboard digital processing, and builds on its execution record on Tranches 0, 1,
and 2.

u United Kingdom (UK) National Air Traffic Services (NATS) Flight Data
Processing (FDP) Evolution. Leidos received a $170 million contract to upgrade
the core flight data processing software under the UK NATS FDP Evolutions
program, replacing legacy systems with a modern architecture that automatically
delivers real-time flight data to air traffic controllers. This award
strengthens Leidos' global position in next-generation air traffic management
and reinforces its pedigree for upcoming modernization projects.

u U.S. Cyber Command (CYBERCOM) Cyberspace Operations Support Services (COSS).
Leidos secured a five-year, $160 million contract to support USCYBERCOM's J3,
Cyber National Mission Force, and Joint Task Force Area with planning, training,
strategy, doctrine development, and campaign assessment. This award marks
Leidos' first cyber operations award

Leidos a $155 million contract to continue to advance flight systems integration
and flight vehicle subsystem development for a sea-based theater nuclear
deterrent.

u Customer & Border Patrol (CBP) and Immigration & Customs Enforcement (ICE)
Shared Electronic Health Record (EHR) Platform and Support Services. Leidos
secured a five-year, $129 million single-award blanket purchase agreement (BPA)
to implement and sustain a modern EHR system for U.S. CBP and ICE. Under the
initial call order, Leidos will deploy an integrated EHR system for ICE,
consolidating core healthcare capabilities, enabling secure information
exchange, and improving continuity of care. Building on the company's MHS
GENESIS success, the award establishes and foundation for expansion across
Department of Homeland Security (DHS) components.

u U.S. Army Long-Range Persistent Surveillance—Mobile (ALPS-M) and U.S. Marine
Corps Multi-Role Air Defense Radar (MRADR). The Army awarded Leidos a $95
million contract to deliver 10 prototypes of its current ALPS capability, which
is being deployed globally through the U.S. Air Force's Air Base Air Defense
System - Missile Defense (ABADS-MD) program. Separately, Leidos secured a $41
million contract to build 14 additional MRADR systems for the Marine Corps.
Together, these awards demonstrate sustained customer demand for Leidos' family
of persistent surveillance sensing technologies.

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 margin or diluted EPS 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 at this time. The amounts of these
deductions may be material and, therefore, could result in projected net income
margin and diluted EPS being materially less than what may be implied by
projected adjusted EBITDA margins and non-GAAP diluted EPS.

Beginning fiscal 2026, we completed a realignment of our reporting structure,
which resulted in the identification of four reportable segments: Intelligence &
Digital, Health, Homeland and Defense. Additionally, we separately present the
unallocable costs associated with corporate functions as Corporate. We commenced
operating and reporting under the new organizational structure effective the
first day of fiscal 2026. As a result of this change, prior year segment results
have been recast to reflect the current reportable segment structure.

Intelligence & Digital revenues grew 1% year-over-year to $1.55 billion driven
by recent contract awards and higher volumes and expanded scope across key
Intelligence Community programs offset by reductions in certain federal civilian
IT programs. Operating income margin was 11.1% compared to 9.2% in the prior
year quarter, and non-GAAP operating income margin was 11.5%, up from the prior
year quarter. Profitability enhancements were driven by a mix of better program
execution, including strong award fee scores and disciplined cost management
across the segment.
                                                                                
  Health                                                                        
                                                                                
Health revenues of $1.07 billion decreased by 12% compared to the prior year
quarter. Health operating income margin for the quarter was 22.5%, compared to
26.8% in the prior year quarter, and non-GAAP operating income margin was 22.8%,
compared to 27.3% in the prior year quarter. The declines in revenues and
margins were driven by expected program shifts and reduced volumes on managed
health services programs.
                                                                                
  Homeland                                                                      
                                                                                
Homeland revenues of $1.02 billion increased by 32% compared to the prior year
quarter. Revenue growth was driven by strong demand for air traffic management
and electric power distribution engineering solutions as well as $142 million
from the acquisition of ENTRUST Solutions. Operating income margin for the
quarter was 7.9%, compared to 6.5% in the prior year quarter, and non-GAAP
operating margin increased to 11.3% from 7.5% in the prior year quarter.
Profitability enhancements reflect an increased mix of higher-margin commercial
work and disciplined cost management across the segment.

Defense revenues of $992 million were up 3% compared to the prior year quarter
led by increased demand for several defense technology areas including air
defense, sensing, and C5ISR systems. Defense operating income margin for the
quarter was 8.7%, compared to 8.2% in the prior year quarter, and non-GAAP
operating margin was 9.7%, compared to 9.8% in the prior year quarter.

  UNAUDITED BACKLOG BY REPORTABLE SEGMENT                                       
                                                                                
Backlog represents the revenues we expect to recognize under negotiated
contracts and unissued task orders on sole source IDIQ contracts, to the extent
we believe their execution and funding to be probable. Backlog does not include
potential task orders expected to be awarded under multiple award IDIQ
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. Unfunded backlog
represents all remaining value on task orders that is not funded, including
options, that we expect to recognize as well as expected future task orders
under sole source IDIQ contracts.

The estimated value of backlog as of the dates presented was as follows:

Leidos uses and refers to non-GAAP operating income, non-GAAP operating margin,
adjusted EBITDA, adjusted EBITDA margin, non-GAAP diluted EPS, non-GAAP free
cash flow and non-GAAP 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 representation
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.

capture 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.

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

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

u Amortization of acquired intangible assets – Represents the amortization of
the fair value of the acquired intangible assets. We do not exclude the revenue
associated with these acquired intangible assets from non-GAAP operating income.

u Asset impairment charges – Represents impairments of long-lived intangible
assets and other assets.

is computed by excluding the discrete items from operating income and the
following discrete items from non operating income.

u Settlement loss on pension plan buy-out – Represents the settlement loss in
connection with the buy-out of our UK defined benefit pension plan.

u Acquisition related financing costs – Represents the cost associated with the
termination of the bridge loan facility in connection with the acquisition of
Entrust.

income and non-GAAP non operating income and their related tax impacts.

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.

is computed by deducting expenditures for property, equipment and software from
net cash provided by (used in) operating activities.

is computed by dividing non-GAAP 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 common stockholders.

(1) Asset markdowns associated with restructuring activities were recorded to
"Cost of revenues" in the condensed consolidated statements of operations.

(2) Calculation uses an estimated statutory tax rate on non-GAAP adjustments.

(3) Earnings per share is computed independently for each of the non-GAAP
adjustments presented and therefore may not sum to the total non-GAAP earnings
per share due to rounding.
