                 Dayton Superior Corporation Announces
                Second Quarter 2003 Earnings Estimates

    DAYTON, Ohio--(BUSINESS WIRE)--May 29, 2003--Dayton Superior
Corporation today announced its earnings estimates for the second
quarter of 2003.
    Based on preliminary internal estimates, management expects that
the Company's operating income in the second quarter of 2003 will be
in the range of $10.0 million to $11.8 million, depreciation and
amortization will be in the range of $5.2 million to $5.3 million and
facility closing and severance expense will be in the range of $0.3
million to $0.4 million. Therefore, management expects that the
Company's earnings before interest expense, provision (benefit) for
income taxes, depreciation expense, amortization of intangibles and
facility closing and severance expense ("EBITDA") for the second
quarter of 2003 will be in the range of $15.5 million to $17.5
million. The Company believes that certain investors may find EBITDA
to be a useful tool for measuring a company's ability to service its
debt. EBITDA does not represent cash flows from operating activities,
as defined by U.S. generally accepted accounting principles, and is
not a substitute for operating income as an indicator of operating
performance or operating cash flows as a measure of liquidity. The way
we calculate EBITDA may differ from that used by other companies and,
therefore, comparability may be limited. Actual results for the
quarter will depend on numerous factors, many of which are beyond the
Company's control.

    Dayton Superior Corporation, with 2002 revenues of $378 million,
is the largest North American manufacturer and distributor of metal
accessories and forms used in concrete construction and metal
accessories used in masonry construction and has an expanding
construction chemicals business. The Company's products, which are
marketed under the Dayton Superior(R), Dayton/Richmond(R), Symons(R),
American Highway Technology(R) and Dur-O-Wal(R) names, among others,
are used primarily in two segments of the construction industry:
non-residential buildings and infrastructure construction projects.

    Certain statements made herein concerning anticipated future
performance are forward-looking statements. These forward-looking
statements are based on estimates, projections, beliefs and
assumptions of management and are not guarantees of future
performance. Actual future performance, outcomes and results may
differ materially from those expressed in forward-looking statements
as a result of a number of important factors. Representative examples
of these factors include (without limitation) the cyclical nature of
nonresidential building and infrastructure construction activity,
which can be affected by factors outside Dayton Superior's control,
such as the general economy and governmental expenditures; Dayton
Superior's ability to successfully integrate acquisitions on a timely
basis; the seasonality of the construction industry; and the amount of
debt Dayton Superior must service. Quarterly results are also subject
to the timing of revenue recognition relating to equipment sales,
which tend to be unpredictable. This list of factors is not intended
to be exhaustive, and additional information concerning relevant risk
factors can be found in Dayton Superior's Registration Statement on
Form S-4, Annual Report on Form 10-K, Quarterly Reports on Form 10-Q
and Current Reports on Form 8-K filed with the Securities and Exchange
Commission.
