Exhibit 99: Press Release dated March 25, 2004: Headwaters Incorporated Refinances its Senior Secured Credit Facility HEADWATERS INCORPORATED REFINANCES ITS SENIOR SECURED CREDIT FACILITY SOUTH JORDAN, UTAH, March 25, 2004 - HEADWATERS INCORPORATED (NASDAQ:HDWR), announced today the execution of a commitment letter with Bank One to provide for the refinancing of Headwaters' senior secured credit facilities. It is anticipated that the new credit facilities will be in place by the end of March. Headwaters' current senior secured credit facilities consist of a Term B Loan, with a currently outstanding balance of approximately $70 million, and a revolving credit arrangement of $20 million against which no funds have been drawn. The interest rate on the current senior secured credit facility is 425 basis points over Libor, or approximately 5.4% today. The new senior secured credit facilities will consist of a Term Loan of $50 million and a revolving credit arrangement of $50 million. The interest rate ranges from 175 - 250 basis points over Libor, depending upon the Company's leverage and certain other covenants. The initial interest rate will be 225 basis points over Libor or approximately 3.5%. The term loan is due November 2007 and required principal payments are based upon a 10 year amortization with a balloon payment due at maturity. Headwaters anticipates a $20 million repayment of the current debt of $70 million from cash on hand which will happen simultaneously with the refinancing of the remaining $50 million from proceeds received from the new senior secured credit facility with Bank One. Based on the twelve months ended December 31, 2003, Headwaters debt to EBITDA ratio will be approximately .5 to 1 immediately after the refinancing occurs. "The anticipated interest savings to Headwaters from this new senior credit facility should exceed $1 million per year. We appreciate the new relationship we have established with Bank One and are pleased with the current strength of the debt markets and the flexibility and favorable pricing that the new senior credit facilities provides," said Steven G. Stewart, Headwaters' Chief Financial Officer. "We will use the $50 million revolver that is not initially drawn down and cash on hand to help finance some of the acquisitions that we are currently considering."
