(Exact name of Registrant as specified in its charter) Delaware 1-9549 04-2925807 (State or other (Commission (I.R.S. Employer jurisdiction of File Number) Identification Number) incorporation or organization) 81 Wyman Street Waltham, Massachusetts 02454-9046 (Address of principal executive offices) (Zip Code) (781) 622-1000 (Registrant's telephone number including area code) This Form 8-K contains forward-looking statements that involve a number of risks and uncertainties. Important factors that could cause actual results to differ materially from those indicated by such forward-looking statements are set forth under the heading "Forward-looking Statements" in Exhibit 13 to Thermo TerraTech Inc.'s Annual Report on Form 10-K for the year ended April 4, 1998. These include risks and uncertainties relating to: dependence of Thermo TerraTech's businesses on environmental regulation and on sales to government entities; potential environmental, regulatory, and professional liability; intense competition; development and commercialization of technology; dependence on the availability of certain raw materials; possible obsolescence of Thermo TerraTech's services due to technological change; Thermo TerraTech's acquisition and spinout strategies; uncertainties associated with the availability of government funding; the effect of seasonal influences on Thermo TerraTech's performance; and the potential impact of the year 2000 on processing date-sensitive information. Item 5. Other Events On September 29, 1998, Thermo TerraTech Inc. ("Thermo TerraTech") issued a press release announcing that it will record pretax restructuring charges totaling approximately $10 million in its second fiscal quarter, which ends October 3, 1998. A charge of approximately $9 million will be incurred as a result of the decision of Thermo TerraTech's ThermoRetec Corporation subsidiary to close two soil-recycling facilities, which are located in Richmond, California, and Greenville, South Carolina. Thermo TerraTech's five other soil-recycling facilities are unaffected by this action. These charges will reduce second quarter 1999 diluted earnings per share by approximately $.24. Thermo TerraTech estimates that these actions will result in calendar 1999 operating savings of at least $1 million. Item 7.
