WALTHAM, Mass., (January 29, 2009) – Raytheon Company (NYSE: RTN) announced fourth quarter 2008 adjusted income from continuing operations of $466 million or $1.13 per diluted share, compared to $420 million or $0.96 per diluted share in the fourth quarter 2007⁽¹⁾. Reported fourth quarter 2008 income from continuing operations was $421 million or $1.02 per diluted share compared to $634 million or $1.45 per diluted share in the fourth quarter 2007. Fourth quarter 2008 income from continuing operations included a $45 million or $0.11 per diluted share unfavorable adjustment due to the impact of pension investment returns

⁽¹⁾ Adjusted EPS and income from continuing operations are non-GAAP financial measures. Fourth quarter and full-year 2008 adjusted EPS and income from continuing operations exclude the $45 million ($69 million pretax) or $0.11 per diluted share unfavorable adjustment due to the impact of pension investment returns on existing contracts (the “CAS Pension Adjustment”). Fourth quarter and full-year 2007 adjusted EPS and income from continuing operations exclude a $0.49 per diluted share ($214 million) and $0.49 per diluted share ($219 million) favorable adjustment, respectively, due to certain tax-related benefits. Please see attachment G for a reconciliation of these measures to EPS and income from continuing operations under GAAP and a discussion of why the Company is presenting this information.

on existing contracts (the “CAS Pension Adjustment”). Fourth quarter 2007 income from continuing operations included a $214 million or $0.49 per diluted share favorable adjustment due to tax-related benefits.

“Raytheon had a successful 2008 with strong bookings, a record backlog and solid growth in sales and operating income,” said William H. Swanson, Raytheon Chairman and CEO. “Our advanced technologies, program performance and diverse portfolio of products and services are uniquely suited to meet customer requirements and position us well for the future.”

Net sales in the fourth quarter 2008 were $6.1 billion compared to $6.0 billion in the fourth quarter 2007. The Company’s solid sales performance in the fourth quarter 2008 was achieved with 3 fewer work days than the fourth quarter 2007.

The Company continued to generate solid operating cash flow in the fourth quarter 2008. Operating cash flow from continuing operations in the fourth quarter 2008 was $444 million compared to $941 million in the fourth quarter 2007. The change was primarily due to $381 million in tax refunds in the fourth quarter 2007. The Company also made $160 million more in discretionary cash contributions to its pension plans in the fourth quarter 2008 ($660 million in 2008 compared to $500 million in 2007).

The Company ended the year with $50 million of net debt. Net debt is defined as total debt less cash and cash equivalents.

Full-Year Financial Results

Full-year 2008 adjusted income from continuing operations was $1.7 billion or $4.06 per diluted share, compared to $1.5 billion or $3.31 per diluted share in 2007⁽²⁾. Reported full-year 2008 income from continuing operations was $1.7 billion or $3.95 per diluted share compared to $1.7 billion or $3.80 per diluted share in 2007. Full-year 2008 income from continuing operations included the $45 million or $0.11 per diluted share unfavorable CAS Pension Adjustment. Full-year 2007 income from continuing operations included a $219 million or $0.49 per diluted share favorable adjustment due to tax-related benefits.

2008 net sales were $23.2 billion compared to $21.3 billion in 2007, an increase of 9 percent. All of Raytheon’s businesses contributed to the Company’s sales growth.

The Company generated excellent operating cash flow for the year. Operating cash flow from continuing operations was $2.0 billion in 2008 compared to $1.2 billion in 2007. The increase in operating cash flow in 2008 was primarily due to a reduction in working capital items, lower net cash tax payments and lower discretionary cash contributions made to the Company’s pension plans. The Company paid $448 million in net cash taxes in 2008, compared to $734 million in 2007 (which included $631 million in tax payments attributable to the gain on the sale of Raytheon Aircraft Company (RAC) and $381 million in tax refunds). The Company also made $660 million in discretionary cash contributions to its pension plans in 2008 compared to $900 million in 2007.

As part of its previously announced share repurchase program, the Company repurchased 14.1 million shares of common stock for $680 million in the fourth quarter 2008 and 30.7 million shares for $1.7 billion for the year.

⁽²⁾ Adjusted EPS and income from continuing operations are non-GAAP financial measures. Full-year 2008 adjusted EPS and income from continuing operations exclude the $45 million ($69 million pretax) or $0.11 per diluted share unfavorable CAS Pension Adjustment. Full-year 2007 adjusted EPS and income from continuing operations exclude a $0.49 per diluted share ($219 million) favorable adjustment due to certain tax-related benefits.

* Preliminary Adjusted Summary Financial Results include non-GAAP financial measures which exclude the impact of certain items noted below. The 2008 adjusted measures exclude the $69 million pre-tax, $45 million after-tax, or $0.11 per diluted share unfavorable adjustment due to the impact of pension investment returns on existing contracts. Fourth quarter and full-year 2007 adjusted income and EPS from continuing operations exclude a favorable adjustment of $214 million or $0.49 per diluted share and $219 million or $0.49 per diluted share, respectively, due to certain tax-related benefits. See attachment G for a reconciliation of these measures to the comparable GAAP measures and a discussion of why the Company is presenting this information.

** Net income in 2007 included $885 million or $1.99 per diluted share in discontinued operations primarily from Raytheon Aircraft Company (RAC) and Flight Options (FO) which were sold in 2007.

Preliminary Return on Invested Capital Non-GAAP Financial Measure

Fourth Quarter 2008

We define Return on Invested Capital (ROIC) as income from continuing operations plus after-tax net interest expense plus one-third of operating lease expense after-tax (estimate of interest portion of operating lease expense) divided by average invested capital after capitalizing operating leases (operating lease expense times a multiplier of 8), adding financial guarantees less net investment in Discontinued Operations, and adding back the impact of Statement of Financial Accounting Standards No. 158, Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans (SFAS No. 158). ROIC is not a measure of financial performance under generally accepted accounting principles (GAAP) and may not be defined and calculated by other companies in the same manner. ROIC should be considered supplemental to and not a substitute for financial information prepared in accordance with GAAP. We use ROIC as a measure of efficiency and effectiveness of our use of capital and as an element of management compensation.

* This Reconciliation of Non-GAAP Measures in Preliminary Statement of Operations Information includes certain non-GAAP financial measures under the “Adjusted” columns and sets forth a reconciliation of such measures to the comparable GAAP measure under the “GAAP” column. The non-GAAP financial measures should be considered supplemental to and not a substitute for financial performance in accordance with GAAP. We use the adjusted measures to facilitate management’s internal comparisons to the Company’s historical operating results, to competitors’ operating results, and to provide greater transparency to investors of supplemental information used by management in its financial and operational decision-making, including management’s evaluation of the Company’s operating performance. The 2008 adjusted measures exclude an unfavorable adjustment to reflect the impact of the increase in estimated future pension costs on existing contracts recorded in the fourth quarter of 2008 (the “CAS Pension Adjustment”). Pension costs as calculated under the U.S. Government Cost Accounting Standards (CAS) are a component of our estimated costs to complete each of our contracts. On an annual basis, we update our estimate of future CAS pension costs based upon actual asset returns and other actuarial factors. When these estimated future costs increase, which occurred at December 31, 2008 driven mainly by the significant decline in the value of our pension assets, the estimated costs to complete each existing contract increases. The amounts of revenue and profit which are recognizable based upon our estimated percent complete and expected margins on our contracts, principally on our fixed price contracts, were reduced. In the fourth quarter, we recorded a cumulative catch-up adjustment for this reduction in revenue and profit of $69 million pretax, $45 million after-tax or $0.11 per diluted share as part of Corporate and Eliminations consistent with our internal management reporting and performance evaluation. The components of the CAS Pension Adjustment by business are as follows: IDS - $20 million, IIS - $7 million, MS - $14 million, NCS - $12 million, SAS - $12 million and TS - $4 million. Fourth quarter and full-year 2007 adjusted income and EPS from continuing operations exclude a favorable adjustment of $214 million or $0.49 per diluted share and $219 million or $0.49 per diluted share, respectively, due to certain tax-related benefits.
