SAIC Announces Financial Results for the Second Quarter of Fiscal Year 2015

MCLEAN, VA, September 9, 2014 — Science Applications International Corporation (NYSE: SAIC), a leading technology integrator providing full life-cycle services and solutions in the technical, engineering, and enterprise information technology markets, today announced financial results for the second quarter ended August 1, 2014. SAIC commenced operations on September 27, 2013 (during the third quarter of fiscal 2014) following completion of a spin-off transaction from its former parent.

“As we near our one year anniversary as an independent company, our strategy to increase shareholder value remains unchanged,” said Tony Moraco, SAIC chief executive officer. “Our second quarter results of stable revenue, improving margins, solid cash flow, and predictable capital deployment demonstrate our commitment to executing this strategy.”

Summary Operating Results

Revenues for the second quarter were $952 million ($939 million excluding revenues performed by former parent), compared to $1,034 million during the second quarter of the prior year ($1,005 million excluding revenues performed by former parent). Revenue contracted primarily due to the loss of the DISN Global Solutions program, completion of a program to supply technical support to the Army Reserve and National Guard, and lower material and subcontract revenues on Department of Defense contract vehicles due to delays in the release of contract funding. As expected, revenues performed by former parent decreased during the three months ended August 1, 2014 compared to the same prior year period due to the completion of pre-separation joint work.

Operating income for the quarter was $59 million (6.3% of revenues excluding revenues performed by former parent), up from $38 million (3.8% of revenues excluding revenues performed by former parent) in the prior year period. The increase in operating income was primarily driven by the absence in the current quarter of separation transaction and restructuring expenses as well as improved current quarter contract performance. These impacts were partially offset by reduced income due to revenue contraction.

Net income for the quarter was $34 million compared to $25 million in the prior year period. The increase in net income was primarily driven by higher operating income offset by interest expense during the quarter on long-term debt obtained in September 2013 in conjunction with the spin-off transaction.

Diluted earnings per share was $0.70 for the second quarter. The weighted-average diluted shares outstanding during the quarter was 48.9 million shares.

Cash Generation and Capital Deployment

Cash flow provided by operating activities for the second quarter was $65 million, which was a $2 million improvement compared to the same period in the previous year. As of August 1, 2014, SAIC had $247 million in cash and cash equivalents and $502 million in long-term debt.

During the quarter SAIC deployed $52 million, consisting of $14 million in dividends and $39 million in share repurchases (approximately 919,000 shares) under the SAIC’s previously announced share repurchase program.

Quarterly Dividend Declared

Subsequent to quarter end, the Board of Directors declared a regular quarterly cash dividend of $0.28 per share payable on October 30, 2014, to stockholders of record on October 15, 2014. SAIC intends to continue paying dividends on a quarterly basis, although the declaration of any future dividends will be determined by the Board of Directors each quarter and will depend on earnings, financial condition, capital requirements and other factors.

New Business Awards

Net bookings for the second quarter were approximately $865 million which reflects a book-to-bill ratio of 0.9. A notable award received during the second quarter was:

BACKLOG

(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 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 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 indefinite-delivery/indefinite-quantity (IDIQ), U.S. General Services Administration (GSA) Schedule or other master agreement contract vehicles.

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