Exhibit 99 HEADWATERS COMPLETES ACQUISITION OF ISG RESOURCES -- Combination results in one of the largest coal industry value-added service providers -- Salt Lake City, Utah -- Headwaters Incorporated (Nasdaq: HDWR ), announced today that it has closed its acquisition of Industrial Services Group, Inc. ("ISG") and its wholly-owned subsidiary, ISG Resources, Inc., the nation's largest marketer and manager of coal combustion products. ISG's primary revenue source is the sale of fly ash as a substitute for Portland cement. Fly ash is generated at coal fired power plants, and when used as a replacement of cement, substantially improves the quality and strength of concrete products. The usage of fly ash as a replacement for cement (40% or more in some major building projects) has dramatically increased in recent years. The final terms of the transaction, originally announced on July 16, resulted in Headwaters paying $22.7 million in cash, $10 million in ISG management-financed subordinated debt and 2.1 million shares of its common stock as consideration for 100% of ISG. In addition, Headwaters has refinanced $181 million of outstanding indebtedness of ISG with a new $155 million senior secured debt facility, $20 million of newly issued subordinated debt, which includes the $10 million of ISG management-financed debt, and cash from operations. Headwaters has available a $20 million senior debt revolver for its future needs. In connection with the acquisition, ISG separately announced the results of its tender offer for $100 million ISG Resources, Inc. 10% senior notes due April 15, 2008. All of the senior notes have been validly tendered and accepted for payment as of today. ISG noteholders who tendered by the consent date will receive $1,010 per note tendered, and the remaining noteholders will receive $1,000 per note, plus accrued interest, from the trustee following funding of the notes. Kirk Benson, CEO of Headwaters, stated: "We are excited to have completed this landmark transaction for Headwaters, and are well on our way towards successfully integrating the ISG and Headwaters businesses. Our new company is a clear leader in adding value to America's abundant coal reserves through technology and services. We see significant benefits for our customers from bringing together Headwaters' pre-combustion technologies with ISG's post-combustion market leadership. ISG has developed a unique position in the coal combustion products market. First, it has the only nationwide distribution and logistics system allowing it to supply high quality fly ash on a reliable basis across the country. ISG has 31 terminals and storage facilities and 90 plant site supply facilities, in addition to over 400 trucks and 1200 railcars. Second, ISG has long-term supply contracts with over 115 power plants in 35 states. Many of ISG's contracts have an existing life in excess of ten years. Third, ISG has proprietary treatment technology that adds value to fly ash, in many instances making it marketable. These unique characteristics set ISG apart as the industry leader with a strong competitive position, as well as significant growth opportunities." Steve Creamer, CEO of ISG, stated: "This is a great opportunity to bring together two technology leaders in the coal industry and to expand the range of services each individual company can bring to the power industry. The management at ISG is committed to the combined company and we are looking forward to working with Headwaters on a long-term basis." Headwaters reiterated that the ISG acquisition will be accretive to earnings per share for the 2003 fiscal year, which begins on October 1. Due to the short period for which ISG's results will be consolidated with Headwaters for fiscal 2002, Headwaters does not anticipate any meaningful benefit from the ISG acquisition in its fiscal 2002 results. Morgan Stanley acted as financial advisor to Headwaters for the transaction and served as Lead Arranger on the financing package. General Electric Capital Corporation is Administrative Agent for the senior facility, and Allied Capital Corporation is the lead subordinated lender. Bank of America Securities acted as financial advisor to ISG.
