- Revenues: $2.47 billion

- Operating Income: $75 million

-Net New Bookings: $1.86 billion (book-to-bill ratio of 0.75)

MCLEAN, Va., September 4, 2013 — SAIC, Inc. (NYSE: SAI), a scientific, engineering, and technology applications company, today announced financial results for the second quarter of fiscal year 2014, which ended August 2, 2013.

“This quarter we experienced both operational successes and challenges. Our financial results and outlook were impacted by a number of discrete items relating to the planned separation of SAIC into two companies, net charges for underperforming programs and contracts coupled with the ongoing effects of sequestration. As a result, we have prudently chosen to lower our fiscal year 2014 guidance, not only to address these items but because of the continuing challenges posed by the current environment. Nevertheless, the business continues to generate strong operating cash flow, which exceeded $200 million in the quarter. Furthermore, we continue to make progress on our cost containment programs and improved rates that will benefit us as we move forward ultimately as two highly focused and purpose built companies,” said John P. Jumper, SAIC Chairman and Chief Executive Officer. “The entire SAIC leadership team and our nearly 37,000 employees remain excited and committed to the planned separation and the enormous potential of two new companies to be more competitive in the markets they will address.”

Summary Results

Revenues for the second quarter of fiscal year 2014 were $2.47 billion, compared to $2.83 billion in the second quarter of fiscal year 2013, reflecting a revenue contraction of 12 percent and an internal revenue contraction of 15 percent. Revenues were impacted by the ramp down of certain contracts, drawdowns of overseas U.S. military forces and the reduction of the U.S. Government budget, partially offset by growth in the Health and Engineering segment primarily resulting from the fiscal year 2013 acquisition of maxIT Healthcare Holdings, Inc. The ramp down of two programs, Joint Logistics Integration (JLI) and DISN Global Solutions (DGS), accounted for 5 percent of the revenue contraction year over year. Internal revenue contraction for the quarter would have been 13 percent without the negative impact of $38 million in revenues for the one less working day as compared to the second quarter of fiscal year 2013.

Operating income for the quarter was $75 million (3.0 percent of revenues), down from $189 million (6.7 percent of revenues) in the second quarter of fiscal year 2013. The reduction in operating income was primarily attributable to $35 million of separation transaction expenses, a non-cash $30 million intangible asset impairment charge, $29 million for the increase in the net unfavorable changes in contract cost estimates and $26 million related to the contraction in revenue.

Diluted earnings per share from continuing operations for the quarter were $0.13, down 59 percent from $0.32 in the second quarter of fiscal year 2013. This decline was primarily attributable to the aforementioned operating income reductions that translated to a reduction in income from continuing operations of $64 million. The diluted share count for the quarter was 341 million, up 2 percent from 333 million in the second quarter of fiscal year 2013.

Segment Operating Results

Effective February 1, 2013, in preparation for the planned separation transaction, the Company redefined its reportable segments into the reportable segments referenced in the chart below. Following completion of the planned separation transaction, the Technical Services and Information Technology segment will operate as an independent publicly traded company under the name Science Applications International Corporation, and the Health and Engineering and National Security Solutions segments will operate as a separate independent publicly traded company under the name Leidos Holdings, Inc. The segment information for the second quarter of fiscal year 2013 has been recast to give effect to the change in reportable segments and for discontinued operations.

Health and Engineering

Health and Engineering revenues increased $34 million, or 8 percent, for the second quarter of fiscal year 2014 as compared to the second quarter of fiscal year 2013.

Revenue growth was due to the August 2012 acquisition of maxIT Healthcare Holdings, Inc., a provider of healthcare IT consulting services to commercial clients. Internal revenue contracted by 8 percent and internal revenue would have contracted by 7 percent without the negative impact of $6 million in revenues for the one less working day as compared to the second quarter of fiscal year 2013. Internal revenue contraction reflects a decline in our health business driven by program completions and lower levels of U.S. Government funding including reductions in Medicaid and Medicare reimbursements and a decline in engineering services for U.S. Government customers. These declines were partially offset by increased unit deliveries and related maintenance of our non-intrusive inspection engineering products.

Health and Engineering operating income decreased $30 million, or 88 percent, for the second quarter of fiscal year 2014 as compared to the second quarter of fiscal year 2013. The decrease was primarily attributable to an impairment charge of intangible assets acquired in August 2010 in connection with the acquisition of Reveal Imaging Technologies, a provider of threat detection products and services. There was also an increase in the net unfavorable changes in contract estimates primarily related to an energy fixed-priced construction project and lower operating income from the commercial health business primarily due to lower margins coupled with an increase in intangible asset amortization expense. These decreases were partially offset by higher revenue attributed to deliveries of engineering products, which typically generate higher margins.

National Security Solutions

National Security Solutions revenues decreased $187 million, or 15 percent, all of which was internal revenue contraction, for the second quarter of fiscal year 2014 as compared to the second quarter of fiscal year 2013. Revenue contraction for the quarter would have been 14 percent without the negative impact of $16 million in revenues for the one less working day as compared to the second quarter of fiscal year 2013. Revenue contraction was primarily attributable to the ramp down of the JLI program for tactical mine resistant ambush protected vehicles and the completion of several intelligence programs, with the remainder of the decline driven by the reduction of the U.S. Government budget resulting from sequestration and drawdowns of overseas U.S. military forces. This contraction was partially offset by increased revenues related to three new intelligence contracts for classified customers and one new intelligence information processing, exploitation, and dissemination program.

National Security Solutions operating income decreased $25 million, or 24 percent, for the second quarter of fiscal year 2014 as compared to the second quarter of fiscal year 2013. This decrease was primarily attributable to lower revenues and a net unfavorable change in contract estimates compared to a net favorable change in the second quarter of fiscal year 2013, primarily attributable to increased expenses on two international fixed price development programs, partially offset by a reduction in indirect costs.

Technical Services and Information Technology

Technical Services and Information Technology revenues decreased $193 million, or 16 percent, all of which was internal revenue contraction, for the second quarter of fiscal year 2014 as compared to the second quarter of fiscal year 2013. Revenue contraction for the quarter would have been 15 percent without the negative impact of $16 million in revenues for the one less working day as compared to the second quarter of fiscal year 2013. Revenue contraction was primarily attributable to the ramp down of the DGS program with the Defense Information Systems Agency and the completion of a network operational management program for the U.S. Forces in Afghanistan, with the remainder of the decline driven by the slower U.S. Government contracting ordering environment resulting from sequestration.

Technical Services and Information Technology operating income decreased $7 million, or 9 percent, for the second quarter of fiscal year 2014 as compared to the second quarter of fiscal year 2013. This decrease was primarily due to lower revenues, including the ramp down of the DGS program which had relatively higher profit margins, partially offset by a reduction in indirect costs.

Corporate and Other

Corporate and Other segment operating loss for the quarter increased from the second quarter of fiscal year 2013 primarily due to expenses incurred in connection with the planned separation transaction of $35 million and costs to establish infrastructures for the two future companies of $14 million.

Cash Generation and Capital Deployment

Cash flow provided by continuing operations for the quarter was $217 million which is relatively consistent with $200 million for the second quarter of fiscal year 2013.

During the quarter, the Company paid a cash dividend of $1.12 per share, which included a special cash dividend of $1.00 per share that was paid in June 2013, for a total cash outlay of $383 million. The Company intends to continue paying dividends on a quarterly basis, although the declaration of any future dividends will be determined by the Company’s Board of Directors each quarter and will depend on earnings, financial condition, capital requirements and other factors.

As of August 2, 2013, the Company had $462 million in cash and cash equivalents and $1.3 billion in long-term debt.

New Business Awards

Net business bookings totaled $1.86 billion in the second quarter of fiscal year 2014, representing a book-to-bill ratio of 0.75. Notable recent awards received include:

The Company’s backlog of signed business orders at the end of the second quarter of fiscal year 2014 was $15.88 billion, of which $4.56 billion was funded. As compared to the end of the second quarter of fiscal year 2013, total backlog decreased 4 percent and funded backlog decreased 17 percent. Negotiated backlog does not include any estimate of future task orders expected to be awarded under IDIQ, GSA Schedule or other master agreement contract vehicles.

Forward Guidance

Based upon its operating and business development performance through the second quarter of the fiscal year, the Company revised its previously issued guidance for revenues and diluted earnings per share from continuing operations. These expectations are:

The guidance is based on SAIC, Inc. operating for the full fiscal year as one company, yet includes substantial costs to prepare for the previously announced separation

transaction. If the separation occurs during fiscal year 2014 as is currently contemplated, it is expected that guidance policies will be provided for each of the two separate companies at the time of the separation. Fiscal year 2014 guidance excludes the impact of potential future acquisitions and other non-ordinary course items.

BACKLOG BY REPORTABLE SEGMENT

(Unaudited, $ in millions)

Backlog represents the estimated amount of future revenues to be recognized under negotiated contracts as work is performed and excludes contract awards which have been protested by competitors. SAIC, Inc. segregates its 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 on a quarterly or annual basis 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 on contracts, which may cover multiple future years, under which SAIC, Inc. is obligated to perform, less revenues previously recognized on these contracts. Negotiated unfunded backlog represents the estimated amounts of revenue to be earned in the future from (1) negotiated contracts for which funding has not been appropriated or otherwise authorized and (2) unexercised priced contract options. Negotiated unfunded backlog does not include any estimate of future potential task orders expected to be awarded under IDIQ, GSA Schedule or other master agreement contract vehicles.

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

INTERNAL REVENUE GROWTH (CONTRACTION) PERCENTAGE CALCULATIONS (NON-GAAP RECONCILIATION)

(Unaudited, $ in millions)

In this release, SAIC, Inc. refers to internal revenue growth (contraction) percentage, which is a non-GAAP financial measure that is reconciled to the most directly comparable GAAP financial measure. The company calculates its internal revenue growth (contraction) percentage by comparing reported revenue for the current year period to the revenue for the prior year period adjusted to include the actual revenue of acquired businesses for the comparable prior year period before acquisition. This calculation has the effect of adding revenue for the acquired businesses for the comparable prior year period to the company’s prior year period reported revenue.

SAIC, Inc. uses internal revenue growth (contraction) percentage as an indicator of how successful it is at growing its base business and how successful it is at growing the revenues of the businesses that it acquires. The integration of acquired businesses allows current management to leverage business development capabilities, drive internal resource collaboration, utilize access to markets and qualifications, and refine strategies to realize synergies, which benefits both acquired and existing businesses. As a result, the performance of the combined enterprise post-acquisition is an important measurement. In addition, as a means of rewarding the successful integration and growth of acquired businesses, and not acquisitions themselves, incentive compensation for senior management is based, in part, on achievement of revenue targets linked to internal revenue growth.

The limitation of this non-GAAP financial measure as compared to the most directly comparable GAAP financial measure is that internal revenue growth (contraction) percentage is one of two components of the total revenue growth (contraction) percentage, which is the most directly comparable GAAP financial measure. The company addresses this limitation by presenting the total revenue growth percentage next to or near disclosures of internal revenue growth (contraction) percentage. This financial measure is not meant to be considered in isolation or as a substitute for comparable GAAP measures and should be read only in conjunction with SAIC, Inc.’s consolidated financial statements prepared in accordance with GAAP. The method that the company uses to calculate internal revenue growth (contraction) percentage is not necessarily comparable to similarly titled financial measures presented by other companies.

Internal revenue growth (contraction) percentages were calculated as follows:
