IRVINE, CA (August 4, 2005) - The Keith Companies, Inc. (Nasdaq: TKCI), an
engineering and consulting services firm, today announced financial results for
the second quarter and six months ended June 30, 2005, which included record
quarterly net revenue and gross profit.

SECOND QUARTER AND YEAR TO DATE 2005 RESULTS
     Net revenue for the three months ended June 30, 2005 increased 15.7% to
$28.3 million, while income from continuing operations for the same period
decreased by 25.7% to $1.6 million resulting in diluted earnings per share from
continuing operations of $0.19. This compares to net revenue for the second
quarter of 2004 of $24.5 million, income from continuing operations of $2.1
million and diluted earnings per share from continuing operations of $0.27. The
decrease in both income from continuing operations and earnings per share from
continuing operations resulted primarily from merger-related costs, which are
discussed below.







     Net revenue for the six months ended June 30, 2005 increased 15.5% to $54.2
million, while income from continuing operations for the same period decreased
by 2.8% to $3.5 million resulting in diluted earnings per share from continuing
operations of $0.43. This compares to net revenue for the same period in 2004 of
$46.9 million, income from continuing operations of $3.6 million and diluted
earnings per share from continuing operations of $0.45. The decrease in both
income from continuing operations and earnings per share from continuing
operations resulted primarily from merger-related costs, which are discussed
below.

     "All three of our business segments once again achieved year-over-year net
revenue growth helping to drive record net revenue for the Company in the second
quarter," said Aram Keith, Chairman and CEO of The Keith Companies. "Our
business continued to be positively impacted by the same factors that propelled
record net revenue last quarter. Residential real estate remains strong with no
signs of disruption in demand. In terms of our public works/infrastructure
segment, most of the year-over-year growth was due to our continued ability to
temporarily deploy the talent of some of our under-utilized engineers to provide
services in support of our real estate development segment. Our ability to
cross-utilize our employees in this way is an advantage for us given the tight
market for talented engineers. Our energy/industrial segment delivered net
revenue growth of over 32% this quarter as compared to the prior year. We see
particular strength in areas unrelated to conventional energy projects including
wind power projects and general industrial projects. In addition to the net
revenue growth in the quarter, I'm particularly pleased that we were able to
deliver over a 17% increase to our gross profit during the quarter."

     As noted above, the financial results for the three and six months ended
June 30, 2005 were negatively impacted by merger-related costs incurred in
connection with the proposed merger with Stantec Inc., as previously announced
on April 14, 2005. The Company incurred approximately $1.2 million of
merger-related costs in the second quarter of 2005, which are not deductible for
income tax purposes. Excluding such merger-related costs, adjusted income from
continuing operations would have been $2.6 million and $4.6 million for the
three and six months ended June 30, 2005, respectively, which represents 23.7%
and 26.2% increases for the quarter and six months, respectively, when compared
to the respective prior year periods. Excluding such merger-related costs would
have resulted in adjusted diluted earnings per share from continuing operations
of $0.32 and $0.56 for the three and six months ended June 30, 2005,
respectively. Adjusted diluted earnings per share from continuing operations
increased over 18% and 24% for the quarter and six months ending June 30, 2005,
respectively, over the corresponding prior year periods.

NON-GENERALLY ACCEPTED ACCOUNTING PRINCIPAL ("GAAP") FINANCIAL MEASURES
     The Keith Companies believes investors' understanding of the Company's
total performance is enhanced by disclosing adjusted income from continuing
operations and adjusted diluted earnings per share from continuing operations
for certain non-recurring items, such as its merger-related costs that were
incurred during the second quarter of 2005. The Company defines adjusted income
from continuing operations as the reported items, adjusted to exclude
merger-related costs and the related income tax effects. Adjusted diluted
earnings per common share from continuing operations represents adjusted income
from continuing operations divided by diluted common shares outstanding.





     In reviewing the Company's financial performance for the second quarter and
six months ended June 30, 2005, management focused on adjusted income from
continuing operations and adjusted diluted earnings per share from continuing
operations, among other items, as they exclude the effect of non-recurring
merger-related costs that management believes are not representative of the
Company's core operations for the periods presented. As a result, these non-GAAP
financial measures should help to provide meaningful comparisons of The Keith
Companies' overall performance from one reporting period to another.

     There is a material limitation associated with the use of these non-GAAP
financial measures. Adjusted income from continuing operations excludes the
impact of significant items (in this case, merger-related costs) on current
performance and adjusted diluted earnings per share from continuing operations
does not depict the actual amount earned per diluted share.

     To compensate for the limitations in the non-GAAP financial measures
discussed above, the Company has reconciled the GAAP financial measures to the
non-GAAP financial measures in the table below.

FINANCIAL POSITION
     The Company's balance sheet at June 30, 2005 remained strong with cash and
cash equivalents of $43.9 million, no debt, a current ratio of 4.8:1, and
shareholders' equity of $86.0 million, or $10.75 per common share outstanding at
June 30, 2005.

FINANCIAL GUIDANCE
     Consistent with its practice when it reported financial results for the
first quarter 2005, the Company has discontinued providing financial guidance on
future operating results due to the pending merger with Stantec Inc. Investors
are cautioned not to place any reliance on the financial guidance that the
Company last provided on February 10, 2005.

MERGER WITH STANTEC INC.
     On April 14, 2005, we announced that we entered into an agreement with
Stantec Inc. (TSX: STN) by which the two firms would combine, subject to
approval of the transaction by our shareholders and certain other conditions.

     "We remain very excited about this transaction," said Aram Keith. "As I
have stated before, joining Stantec will substantially accelerate our growth
plans and make The Keith Companies a part of a North American firm with widely
diversified service offerings. Our employees will have access to more service
specialists, experts, and greater technological resources while our clients will
gain access to a wider range of services," concluded Keith.
