Exponent Reports Strong First Quarter 2004 Financial Results

MENLO PARK, Calif., April 19, 2004 - Exponent, Inc. (Nasdaq: EXPO) today reported financial results for the first quarter ended April 2, 2004.

For the first quarter, revenues were $38,766,000 an increase of 11% over $34,815,000 reported in the same period of 2003. Revenues before reimbursements increased 14% to $35,925,000 from $31,471,000 in the same period of 2003. Net income increased by 43% to $3,521,000, or $0.43 per diluted share, as compared to $2,469,000, or $0.32 per diluted share, for the same period of 2003.

“We are especially satisfied with our performance in the quarter and encouraged by the momentum that we are demonstrating in several key areas,” commented President and CEO, Michael R. Gaulke. “We showed continued growth in our defense technology development business, completing the original Advanced Robotic Controller contract for the US Army and commencing a new phase of the program. We continue to work with the Rapid Equipping Force in both Iraq and Afghanistan and have received funding to continue this support for another twelve months. In addition, we have recently been awarded a follow-on contract to continue to provide smartcard failure analysis and Common Access Card (CAC) program support, and we continue to market to other military branches in an effort to broaden our portfolio of clients.

“Our vehicle-centric practices, biomechanics and vehicle analysis, were also strong in the first quarter, as we continued to perform a broad range of accident reconstruction and vehicle testing projects, as well as supported our clients in issues of intellectual property and product recall. We made good progress in other areas, including health sciences and construction disputes, where we continued to build upon important long-term relationships.

“We believe that our strength in the first quarter positions us for growth in 2004, and we are optimistic about our ability to capitalize on our strategic growth initiatives,” concluded Mr. Gaulke.
