PART II -- RULES 12b-25(b) AND (c)

If the subject report could not be filed without unreasonable effort or expense and the registrant seeks relief pursuant to Rule 12b-25(b), the following should be completed. (Check box if appropriate)


  1. The reasons described in reasonable detail in Part III of this form could not be eliminated without unreasonable effort or expense;
  2. The subject annual report, semi-annual report, transition report on Form 10-K, Form 20-F,11-K or Form N-SAR, or portion thereof, will be filed on or before the fifteenth calendar day following the prescribed due date; or the subject quarterly report or transition report on Form 10-Q, or portion thereof will be filed on or before the fifth calendar day following the prescribed due date; and
  3. The accountant's statement or other exhibit required by Rule 12b-25(c) has been attached if applicable.


State below in reasonable detail the reasons why Forms 10-K, 20-F, 11-K, 10-Q, N-SAR, or the transition report portion thereof, could not be filed within the prescribed time period.

Although Astec Industries, Inc. (the "Company") has been working diligently to complete all of the required information for its annual report on Form 10-K for the fiscal year ended December 31, 2004, the Form 10-K could not be completed on or before the March 16, 2005 deadline without unreasonable effort or expense because management experienced delays in completing its evaluation and report on the Company's internal control over financial reporting. As a consequence, the Company's independent registered public accounting firm has been unable to complete its procedures related to the subject Form 10-K, including its attestation on management's assessment on internal control over financial reporting. The Company believes that the subject Form 10-K will be available for filing within the extension period provided by Rule 12b-25(b).
