SAIC Announces Financial Results for the Third Quarter of Fiscal Year 2017

MCLEAN, VA, December 8, 2016—Science Applications International Corporation (NYSE: SAIC), a leading technology integrator providing full life cycle services and solutions in the technical, engineering, intelligence, and enterprise information technology markets, today announced financial results for the third quarter ended November 4, 2016.

“SAIC’s third quarter performance delivered strong results in profitability, cash flow generation and business development,” said Tony Moraco, SAIC Chief Executive Officer. “With our highest book-to-bill since separation, our business development activities continue to gain momentum. Our continued investments position us well to meet the mission of our customers, execute our strategy and create shareholder value.”

Third Quarter Fiscal Year 2017: Summary Operating Results

-1-

Revenues for the third quarter were $1,114 million compared to $1,136 million during the prior year quarter, which represents a decrease of $22 million. Newly awarded programs, such as the Amphibious Combat Vehicle and GSA Enterprise Operations, generated revenues of $47 million during the current quarter. This increase was offset by lower material volume on DoD, federal civilian agency and supply chain programs ($39 million), the expected decline in activity on the Assault Amphibious Vehicle (AAV) program as we near the completion of the prototyping phase ($4 million) and various other decreases across our contract portfolio due to programs that have ended or have experienced lower activity.

Operating income for the quarter was $74 million, or 6.6% of revenues, up from 5.6% for the prior year quarter. The increase was primarily due to lower intangible asset amortization ($5 million), higher net favorable changes in estimates on contracts accounted for using the percentage-of-completion method ($4 million), lower employee benefits expense and a decrease in acquisition and integration costs. These increases were partially offset by increased spending on independent research and development projects and bid and proposal activity.

Net income for the quarter increased $8 million from the comparable prior year period primarily due to increased operating income ($7 million, net of tax) and a lower effective tax rate ($2 million) primarily due to increased research and development credits in the current year. These increases were partially offset by increased interest expense due to costs associated with the amendment to our credit facility.

EBITDA⁽¹⁾ was $86 million for the quarter, or 7.7% of revenues, compared to EBITDA⁽¹⁾ of 7.1% in the comparable prior year quarter. The increase was due to an increase in net favorable changes in estimates on contracts accounted for under the percentage-of-completion method and lower employee benefits expense.

Diluted earnings per share was $0.91 for the quarter. The weighted-average diluted shares outstanding during the quarter was 45.6 million shares.

Cash Generation and Capital Deployment

Total cash flows provided by operating activities for the quarter were $153 million, an increase of $85 million from the comparable prior year period. The increase in operating cash flows over the prior year period was primarily due to a net reduction in working capital investments in Marine Corps platform integration and IT services programs ($39 million) and one less payroll payment in the current quarter.

During the quarter SAIC deployed $54 million of capital, consisting of $14 million in cash dividends and $40 million in plan share repurchases (607 thousand shares) under SAIC’s previously announced share repurchase program.

New Business Awards

Net bookings for the quarter were approximately $1.9 billion, which reflects a book-to-bill ratio of approximately 1.7. SAIC’s estimated backlog of signed business orders at the end of the quarter was approximately $8.2 billion of which $2.0 billion was funded.

SAIC was awarded the following notable contracts during the quarter:

Defense Logistics Agency (DLA): SAIC was awarded a fixed-price, single award, indefinite-quantity contract by the DLA to continue to deliver chemicals, packaged petroleum, oils and lubricants. The contract has a five-year base period of performance, one three-year option and one two-year option for a total contract value of approximately $1.4 billion if all options are exercised.

U.S. Army – US Army Engineering and Support Center: SAIC was awarded the High Performance Computing Modernization Program (HPCMP) Integrated Technical Services (HITS) task order by the U.S. Army Corps of Engineers. SAIC will provide program management and technical support to the HPCMP supercomputing centers. SAIC also will provide systems engineering and technical support to repair, modernize, improve and acquire HPCMP and Department of Defense Supercomputing Resource Center assets and capabilities. The task order has a one-year base period of performance and four one-year options for a total task order value of approximately $575 million if all options are exercised.

U.S. Navy – U.S. Naval Sea Systems Command (NAVSEA): SAIC was awarded a contract by NAVSEA to manufacture MK 48 Mod 7 heavyweight torpedo afterbody and tailcone sections. The contract has a 27-month base period of performance from award to final acceptance and includes options for the procurement of spares, production support material, engineering services, test equipment design and manufacturing, and hardware repair services. The total contract value is expected to be approximately $380 million if all options are exercised.

U.S. Intelligence Community: SAIC was awarded contracts and task orders valued at approximately $149 million, if all options are exercised, by U.S. national security and Intelligence Community customers. Although these customers and the specific nature of these contracts are classified, they all encompass strategic, end-to-end services that help bolster national security.

BACKLOG

(Unaudited)

The estimated value of our total backlog as of the dates presented was:

Backlog represents the estimated amount of future revenues to be recognized under negotiated contracts and task orders as work is performed and excludes contract awards which have been protested by competitors until the protest is resolved in our favor. SAIC segregates backlog into two categories, funded backlog and negotiated unfunded backlog. Funded backlog for contracts with government agencies primarily represents contracts for which funding is appropriated less revenues previously recognized on these contracts, and does not include the unfunded portion of contracts where funding is incrementally appropriated or authorized by the U.S. government and other customers even though the contract may call for performance over a number of years. Funded backlog for contracts with non-government agencies represents the estimated value of contracts which may cover multiple future years under which SAIC is obligated to perform, less revenues previously recognized on these contracts. Negotiated unfunded backlog represents the estimated future revenues to be earned from negotiated contracts for which funding has not been appropriated or authorized, and unexercised priced contract options. Negotiated unfunded backlog does not include any estimate of future potential task orders expected to be awarded under indefinite delivery, indefinite quantity (IDIQ), U.S. General Services Administration (GSA) schedules or other master agreement contract vehicles.

Schedule 5:

NON-GAAP FINANCIAL MEASURES

(Unaudited)

This schedule describes the non-GAAP financial measures included in this earnings release. While we believe that these non-GAAP financial measures may be useful in evaluating our financial information, they should be considered as supplemental in nature and not as a substitute for financial information prepared in accordance with GAAP. Reconciliations, definitions, and how we believe these measures are useful to management and investors are provided below. Other companies may define similar measures differently.

Internal revenue growth

We utilize internal revenue growth (or internal revenue contraction if negative) to evaluate revenue growth after the completion of acquisitions. Internal revenue growth is calculated by comparing our reported revenues for the current year to the reported revenues for the prior year comparable period adjusted to include any pre-acquisition historical revenues of acquired businesses. We also adjust current and prior year revenue to exclude the impact of revenue performed by our former parent company, Leidos Holdings, Inc. (“former Parent”) since revenues on pre-separation joint work are recorded equal to cost and are expected to decline over time. For fiscal 2017, a 53-week fiscal year, we have also adjusted revenue to exclude the estimated impact of the additional week in order to facilitate comparison to the prior year period. We estimate the revenue impact of the additional week by dividing the current year’s revenues for the first quarter by the number of days in the first quarter and multiplying that amount by the number of additional days in the first quarter. We believe that adjusting current year revenues to reflect the impact of the additional week improves comparability since differences in the number of days generally have a direct impact on the amount of revenues earned during the respective periods. We believe that internal revenue growth provides management and investors with useful information in assessing trends on how successful the Company has been in growing revenues as we develop our base business and access new markets and capabilities provided by acquisitions.

Schedule 5 (continued):

NON-GAAP FINANCIAL MEASURES (continued)

(Unaudited)

Adjusted operating income, EBITDA, Adjusted EBITDA, and Adjusted diluted earnings per share

EBITDA is a performance measure that is calculated by taking net income and excluding interest expense, provision for income taxes, and depreciation and amortization. Adjusted EBITDA, adjusted operating income, and adjusted diluted earnings per share are performance measures that exclude acquisition and integration costs that we do not consider to be indicative of our ongoing operating performance as they relate to the Company’s significant acquisition of Scitor. Adjusted EBITDA and adjusted operating income are calculated by excluding acquisition and integration costs from EBITDA and operating income, respectfully. Adjusted diluted earnings per share is calculated by excluding the impact of acquisition and integration costs from diluted earnings per share.  In order to calculate the impact on diluted earnings per share, we use the effective income tax rates for each period excluding the negative effect of certain non-deductible acquisition and integration costs included in net income. We believe that these performance measures provide management and investors with useful information in assessing trends in our ongoing operating performance and may provide greater visibility in understanding the long-term financial performance of the Company.

Schedule 5 (continued):

SCIENCE APPLICATIONS INTERNATIONAL CORPORATION

NON-GAAP FINANCIAL MEASURES (continued)

(Unaudited)

Free Cash Flow

Free cash flow is calculated by taking cash flows provided by operating activities less expenditures for property, plant, and equipment. We believe that free cash flow provides management and investors with useful information in assessing trends in our cash flows and in comparing them to other peer companies, many of whom present a similar non-GAAP liquidity measure. This measure should not be considered as a measure of residual cash flow available for discretionary purposes.
