Exhibit 99 HEADWATERS INCORPORATED TO ACQUIRE ELDORADO STONE o Positions Headwaters in High Growth, "Green" Building Products Manufactured From Fly Ash o Estimated to be Accretive to 2004 and 2005 EPS o Provides National Sales and Distribution Capabilities for Fly Ash Construction Materials o Further Diversifies Headwaters' Cash Flows SOUTH JORDAN, UTAH, APRIL 21, 2004 - HEADWATERS INCORPORATED (NASDAQ: HDWR) today announced that it has entered into a purchase agreement to acquire the ownership interests of Eldorado Stone, LLC, a leading manufacturer of architectural manufactured stone, based in San Marcos, California. Eldorado Stone is being purchased from Graham Partners, a middle market private equity firm, and members of management, for a purchase price of approximately $202 million. The acquisition provides Headwaters with the opportunity to expand the use of environmentally friendly coal combustion materials in high-growth, branded building products. Eldorado Stone will become a wholly-owned subsidiary of Headwaters, integrated into its fly ash construction materials operations. The acquisition, which is subject to regulatory approvals, completion of financing, and other customary conditions, is expected to close in May. The acquisition of Eldorado Stone is expected to be accretive to Headwaters' EPS in 2004 and 2005, without including potential synergies, as well as on a historical pro forma basis. The addition of Eldorado Stone continues the diversification of Headwaters' cash flows for future development of important technological, operational and strategic initiatives. Eldorado Stone has experienced high growth as a result of the increasing demand for manufactured stone in the U.S., the quality of its product, its strong brand name, and management performance. Eldorado Stone's sales grew approximately 24% in 2003, and it has enjoyed approximately 22% annual sales growth over the last three years. It is expected that the company's EBITDA (earnings before interest, income taxes, depreciation and amortization) margins will be in excess of 20%. Participating in one of the fastest growing segments of the building products industry, Eldorado Stone has the potential to continue strong growth in sales, EBITDA and free cash flows. "Headwaters is excited about the acquisition of Eldorado Stone. The addition of Eldorado Stone will add critical mass to our "green" manufactured construction materials division, and significantly enhance its profitability," said Kirk A. Benson, Chairman and CEO of Headwaters. "Eldorado is a strong competitor within a fast-growing market and should strengthen our ash-based construction materials and sales opportunities as we gain access to Eldorado's national sales and distribution system. We are also very pleased to have Eldorado's management team join us at Headwaters and continue to build the Eldorado construction materials business," Mr. Benson further stated. Eldorado Stone had revenues of approximately $100 million in the twelve months ended December 31, 2003. Headwaters will file Form 8-K with complete historical and proforma information upon consummation of the acquisition. The total purchase price for Eldorado Stone is approximately $202 million. The calculation of the final purchase price will vary based on certain adjustments at the time of closing as well as total closing and transaction costs. Headwaters will use existing cash, financing available under its new credit facility with Bank One and new financing to be obtained prior to closing. JPMorgan acted as exclusive strategic M&A advisor to Headwaters on this transaction.
