This Quarterly Update provides information on the changes in the primary drivers of value since our last stock pricing which occurred on October 8, 2004.

This pricing update provides a simplified explanation of the SAIC stock pricing process by focusing on the primary drivers of value in this quarter. Keep in mind that many factors are considered and can impact our stock price. The appraiser of our stock and the SAIC Board of Directors consider events that occur up to the day the price is established and their potential impact (favorable or unfavorable) on the Company in the future. A more detailed description of these factors and the entire stock pricing process is provided in the Stock Pricing Overview on SAIC’s Employee Owner’s Network and SAIC’s stock prospectus.

Pending Sale of Telcordia

SAIC signed a definitive stock purchase agreement to sell our ownership in Telcordia to TTI Holding Corporation, an affiliate of Warburg Pincus LLC and Providence Equity Partners, Inc., for cash of $1.35 billion. The closing of the sale is subject to customary closing conditions. The appraiser’s valuation of Telcordia was based on the expected after-tax proceeds from the sale. This means that Telcordia’s performance was not a factor in the appraiser’s quarterly assessment of SAIC’s operating performance for the financial period ended October 31, 2004. The appraiser’s assessment of the expected after-tax proceeds from the sale of Telcordia, had a minor impact on our stock price.

Primary Drivers of SAIC Stock Value

The two primary drivers of the value of our stock are:

1.SAIC operating performance, and

2.Comparable companies’ stock price trading ratios

The comparable companies analysis performed by our appraiser enables an appropriate multiple to be applied to our operating performance metrics in order to establish a fair market value for our continuing business operations. So these two value drivers are considered together with one serving as a multiplier for the other.

1. SAIC Operating Performance

As part of the stock pricing process, the appraiser and the Board assess the value of SAIC’s operating entities. As you know, one measure of our operating performance is after-tax Segment Operating Income (SOI). This measure of our operating performance is reflected in the earnings term, or “P” element, of our stock pricing formula on a trailing four quarters basis. For the financial period ended October 31, 2004, our trailing four quarters’ after-tax SOI was $377 million, a decrease of 0.4% as compared to our trailing four quarters’ after-tax SOI of $378 million for the four quarter period ended July 31, 2004.

However, because of the pending, definitive sale agreement for Telcordia, the appraiser focused on the operating performance of SAIC without Telcordia. As disclosed in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and Note 2 of the notes to condensed consolidated financial statements in SAIC’s Quarterly Report on Form 10-Q for the period ended October 31, 2004, segment operating income for the nine months ended October 31, 2004 increased over the same period of the prior year for the Regulated and Non-Regulated Other segments. The operating performance of SAIC without Telcordia increased for the trailing four quarters ended October 31, 2004 as compared to the trailing four quarters ended July 31, 2004.

As we explained in the past, the appraiser looks at a variety of operating metrics (Earnings; Cash Flow; Earnings Before Interest & Taxes (EBIT); Earnings Before Interest Taxes Depreciation & Amortization (EBITDA); Future EBITDA; and Revenue) in performing their quarterly appraisal. Some of these are pre-tax measures and some are after-tax measures. The appraiser will also adjust its view of SAIC’s operating metrics to exclude one-time items which, in their estimation, are not reflective of SAIC’s ongoing financial performance. The point to keep in mind is that no one element of data tells the whole story as to how the appraiser and the Board assess SAIC’s operating performance and value.

The company filed its quarterly financial statements with the SEC on December 9, 2004. A Q&A document was posted on EON to help explain our quarterly performance. For more information, please see SAIC’s financial statements filed with the SEC.

Overall, the Company’s underlying operating performance without Telcordia had a favorable impact on our stock price.

2. Comparable Companies

As part of its process, the appraiser analyzes the 5-day trailing average of the trading ratios for our comparables. This is not the same as stock prices. A trading ratio represents the normalized ratio of each company’s stock price to various financial performance indicators such as: Price to Earnings; Price to Cash Flow; Enterprise Value (EV) to Earnings Before Interest & Taxes (EBIT); EV to Earnings Before Interest Taxes Depreciation & Amortization (EBITDA); EV to Future EBITDA; and EV to Revenue. Thus, if a company’s stock price and financial performance increase or decrease by the same percentage in a given quarter, its trading ratio remains unchanged. Remember that the appraiser may apply a premium to our value if we are out-performing our comparables, or a discount to our value if we are under-performing our comparables or for other factors.

In the five days prior to the January 14, 2005 stock pricing, the appraiser’s determination of normalized trading ratios of our comparables were up as compared to the five days prior to the October 8, 2004 pricing. The entire telcom tier was eliminated from our comparables due to the pending, definitive stock purchase agreement to sell our ownership in Telcordia.

The list of comparables is subject to change as SAIC’s business mix changes and as comparable companies merge, dissolve or are acquired. In addition the appraiser may decide to exclude a company from consideration in a particular quarter as a result of certain circumstances, including recent events relating to the comparable company. The list of comparable companies along with their ticker symbols is available on SAIC’s Employee Owner’s Network.

Overall, the market valuation levels of our comparable companies had a favorable impact on our stock price this quarter.

Summary

Taking all relevant factors into consideration, the SAIC Board of Directors established our stock price at $40.55 on January 14, 2005. This represents a 6.3% increase over last quarter, and an 11.0% increase over the past year.

This update explains some of the primary factors or drivers that have influenced the stock price in the last quarter. Individual Board members may have placed more or less weight on these or other factors than other directors. Further, this article does not purport to provide all of the data, analyses and facts considered by the Board, individual directors and the independent appraiser. The stock price is established by the Board of Directors as a group, and the Board collectively agreed on January 14, 2005 that $40.55 per share represented a fair market value for the Class A Common Stock.
