THE KEITH COMPANIES REPORTS RECORD SECOND QUARTER 2002 RESULTS
WITH NET REVENUE AND NET INCOME REACHING AN ALL-TIME HIGH

• 36% increase in net revenue for the quarter ended June 30, 2002

• 18% increase in net income for the quarter ended June 30, 2002

COSTA MESA, CA (August 7, 2002) ... The Keith Companies, Inc. (Nasdaq: TKCI), an engineering and consulting services firm, today announced that net revenue for the second quarter ended June 30, 2002 reached record levels, increasing to $24.1 million, up 36 percent from last year’s second quarter net revenue of $17.7 million.

     The overall increase in net revenue during the 2002 second quarter was due to additional net revenue generated from acquisitions. Net income for the second quarter of this year increased 18 percent to $1.9 million, or earnings per diluted share of $0.24 (based upon 7.9 million diluted weighted average shares outstanding), as compared to net income of $1.6 million, or earnings per diluted share of $0.23 (based upon 7.0 million diluted weighted average shares outstanding) during last year’s second quarter. The increase in diluted weighted average shares outstanding is predominately due to the Company’s Secondary Offering in May 2001.

     Chairman and CEO Aram Keith commented, “I am very pleased with our mix of business lines. Our diversification strategy, which our acquisition activity has noticeably enhanced, continues to be implemented. Each business line has had the opportunity to make noticeable contributions to our success.

     “Looking ahead, I am especially excited about the health of the real estate housing sector. As unprecedented demand continues to build in the U.S. and especially the Sunbelt, both for single family housing and for planned retirement communities, our real estate divisions continue to experience opportunities to enhance our operations in this sector with active developers and builders. Our strong presence in this market is what has set us apart from many of our competitors in the engineering services sector and has helped contribute to making our profit margin one of the highest in our industry,” Keith said.

     Net revenue for the six months ended June 30, 2002 was $45.5 million, an increase of 32 percent from $34.3 million for the six months ended June 30, 2001. This increase was due to additional net revenue generated from acquisitions. Net income for the six months ended June 30, 2002 increased 12 percent to $3.3 million, or earnings per diluted share of $0.42

(based upon 7.8 million diluted weighted average shares outstanding) compared to $3.0 million or earnings per diluted share of $0.46 (based upon 6.4 million diluted weighted average shares outstanding) for the six months ended June 30, 2001. The increase in diluted weighted average shares outstanding is predominately due to the Company’s Secondary Offering in May 2001.

     Keith added, “Continued effort with our strategy of cross-selling has yielded benefits. The added awareness of our divisions about the expertise and services that other divisions provide has led to successfully winning larger portions of several contracts than would have been pursued prior to this strategy.”

     The Company’s June 30, 2002 balance sheet remains strong with cash and securities of $19.2 million, a current ratio of 2.95:1, a debt to equity ratio of 0.03:1 and shareholders’ equity of $57.2 million or $7.80 per share outstanding.

Net Revenue Contributions From Acquisitions

     Acquired companies (ALNM Group, Inc., acquired March 2002; Pacific Engineering Corporation, acquired September 2001; and Universal Energy, Inc., acquired November 2001) contributed $6.4 million in net revenue for the three months ended June 30, 2002 as compared to the corresponding prior year period.

     For the six months ended June 30, 2002, acquired companies contributed $11.6 million in net revenue compared to the six months ended June 30, 2001. This $11.6 million includes one month of revenue contributed by Hook & Associates Engineering, Inc. (acquired January 2001), four months of revenue contributed by ALNM Group, Inc., and a six-month revenue contribution from both Pacific Engineering Corporation and Universal Energy, Inc.

Financial Guidance

     The Keith Companies’ financial guidance for diluted earnings per share for the third and fourth quarters of 2002 remains unchanged from the guidance previously provided. The Company estimates net revenue for 2002 to range from $91.0 million to $96.0 million with estimated diluted earnings per share ranging from $0.90 to $0.97 ($0.25 to $0.29 for the third quarter and $0.22 to $0.26 for the fourth quarter) based upon an estimated 8.0 million weighted average number of diluted shares outstanding for the year.

Conference call to be broadcast live over the Internet
