Exponent Reports Fourth Quarter and Fiscal Year 2008 Results

MENLO PARK, Calif., February 4, 2009 - Exponent, Inc. (Nasdaq: EXPO) today reported financial results for the fourth quarter and fiscal year ended January 2, 2009.

For the 14-week fourth quarter of 2008, revenues before reimbursements increased 10% to $51,620,000, as compared to $46,974,000, in the 13-week fourth quarter of last year. Total revenues increased 4% to $58,892,000, as compared to $56,734,000, in the fourth quarter of 2007. Net income decreased 3% to $5,078,000, or $0.34 per diluted share, as compared to $5,247,000, or $0.33 per diluted share, in the prior year period. EBITDA¹ was $9,073,000, as compared to $9,143,000, in the fourth quarter of 2007.

For the 53-week fiscal year 2008, revenues before reimbursements grew 13% to $206,194,000, as compared to $183,139,000, in the 52-week fiscal year 2007. Total revenues increased 12% to $228,838,000, as compared to $205,148,000, in fiscal year 2007. Net income was up 14% to $23,160,000, or $1.47 per diluted share, as compared to $20,341,000, or $1.25 per diluted share, in the prior year. EBITDA¹ increased 15% to $40,896,000, as compared to $35,649,000, in 2007.

During 2008, Exponent generated $36.4 million in cash flow from operations, used $41.6 million to repurchase its common stock, and closed the year with $57.4 million in cash, cash equivalents and short-term investments.

“In the fourth quarter of 2008 we posted solid revenue growth and were pleased with our operational execution,” commented Michael R. Gaulke, Chairman and CEO. “Our electrical, technology development, mechanics and materials, and environmental practices performed well in the fourth quarter, in addition to our health sciences group. During the quarter we continued to build a strong foundation for the future by adding select talent to the firm.

“We are pleased to have delivered double-digit revenue and net income growth in 2008. For the full year we were able to improve our EBITDA margin while organically growing full-time equivalent employees by 7.3% over the prior year. In addition to our strong financial results for the year, we made significant progress in several of our strategic growth areas including health science consulting, product design consulting, energy consulting, and defense technology development. We continue to believe these areas represent meaningful opportunities for long-term growth.

“In the coming year, we expect our underlying business to grow revenue before reimbursements in the mid- to high-single digits which is slightly lower than our historical expectations due to the uncertain macro-economic environment. In addition, our underlying growth will be reduced by approximately 3% to 4% because in 2008 we had high product sales in technology development, a favorable foreign currency exchange rate environment, and an extra week. During these uncertain economic times we continue to see our demand being driven by product failures, human health hazards, and environmental concerns. Over the longer term our consulting services have been and will continue to be driven by products and processes becoming more technologically complex and geographically dispersed. We believe that Exponent’s differentiated market position as a multidisciplinary engineering and scientific consulting firm with unparalleled technical expertise and experience will allow us to translate these opportunities and market drivers into long-term shareholder value,” concluded Mr. Gaulke.

Such forward-looking statements are subject to the safe harbor created by the Private Securities Litigation Reform Act of 1995. When used in this document and in the documents incorporated herein by reference, the words “anticipate,” “believe,” “estimate,” “expect” and similar expressions, as they relate to the Company or its management, identify such forward-looking statements. Such statements reflect the current views of the Company or its management with respect to future events and are subject to certain risks, uncertainties and assumptions. Should one

or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, the Company’s actual results, performance, or achievements could differ materially from those expressed in, or implied by, any such forward-looking statements. Factors that could cause or contribute to such material differences include the possibility that the demand for our services may decline as a result of changes in general and industry specific economic conditions, the timing of engagements for our services, the effects of competitive services and pricing, the absence of backlog related to our business, our ability to attract and retain key employees, the effect of tort reform and government regulation on our business, and liabilities resulting from claims made against us.

(1) EBITDA is a non-GAAP financial measure defined by the Company as net income before income taxes, interest income, depreciation and amortization. EBITDAS is a non-GAAP financial measure defined by the Company as EBITDA before stock-based compensation. The Company regards EBITDA and EBITDAS as useful measures of operating performance and cash flow to complement operating income, net income and other GAAP financial performance measures. Additionally, management believes that EBITDA and EBITDAS provide meaningful comparisons of past, present and future operating results. Generally, a non-GAAP financial measure is a numerical measure of a company’s performance, financial position or cash flow that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with GAAP. These measures, however, should be considered in addition to, and not as a substitute or superior to, operating income, cash flows, or other measures of financial performance prepared in accordance with GAAP. A reconciliation of the measures to GAAP is set forth below.
