To: scion who wrote (3385 ) 3/29/2006 6:12:10 PM From: scion Respond to of 12518 Effective December 31, 2004, all of our wholly owned domestic subsidiaries (consisting of Symons Corporation; Aztec Concrete Accessories, Inc. ; Dur-O-Wal, Inc.; Trevecca Holdings, Inc.; Dayton Superior Specialty Chemical Corp.; and Southern Construction Products, Inc.) were merged into Dayton Superior Corporation. Dayton Superior is the surviving corporation in the merger and now directly operates the businesses that were being operated by the domestic subsidiaries immediately prior to the merger. DAYTON SUPERIOR CORPORATION FORM 10-K ANNUAL REPORT PURSUANT TO SECTION 13 OR 15(D) OF THE SECURITIES EXCHANGE ACT OF 1934 for the fiscal year ended December 31, 2004 secinfo.com General We believe we are the largest North American manufacturer and distributor of metal accessories and forms used in concrete construction and a leading manufacturer of metal accessories used in masonry construction in terms of revenues. In many of our product lines, we believe we are the market leader, in terms of revenues, competing primarily in two segments of the construction industry: infrastructure construction, such as highways, bridges, utilities, water and waste treatment facilities and airport runways, and non-residential building, such as schools, stadiums, prisons, retail sites, commercial offices, hotels and manufacturing facilities. We derive our revenue from a mix of sales of consumable products and the sale and rental of engineered concrete forming systems. Through our network of 22 service/distribution centers, we serve over 4,000 customers, comprised of independent distributors and a broad array of pre-cast concrete manufacturers, general contractors, subcontractors and metal fabricators. We sell most of our 21,000 products under well established, industry-recognized brand names, and manufacture the vast majority of these products ‘‘in-house.’’ We believe that the breadth of our product offerings and national distribution network allow us to service the largest customer base in the industry by providing a ‘‘one-stop’’ alternative to our customers. We believe that none of our competitors can match our combination of product breadth and national reach. In addition, our nationwide customer base enables us to efficiently cross-sell our products and provides us with a platform from which we can broadly distribute newly developed and acquired product lines. Finally, our national customer base provides us with geographically dispersed sales, which can mitigate the effects of regional economic downturns. ... Products Although almost all of our products are used in concrete or masonry construction, the function and nature of the products differ widely. Most of our products are consumable, providing us with a source of recurring revenue. In addition, while our products represent a relatively small portion of a construction project’s total cost, our products assist in ensuring the on-time, quality completion of those projects. We continually attempt to increase the number of products we offer by using engineers and product development teams to introduce new products and refine existing products. We manufacture and sell products primarily under the Dayton/Richmond®, Aztec®, Symons®, and BarLock® brand names, chemical products under the Dayton Superior®, Conspec®, and Edoco®, brand names, masonry products primarily under the Dur-O-Wal® brand name and welded dowel assemblies and other paving products primarily under the American Highway Technology® name.
