ITEM 4.01. CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT.

On December 16, 2014, Astec Industries, Inc. ("Astec") filed with the Securities and Exchange Commission a current report on Form 8-K disclosing that it had dismissed Ernst & Young LLP ("E&Y") from the role of independent registered accounting firm for Astec, to be effective upon completion by E&Y of its audit of the Company's consolidated financial statements as and for the year ending December 31, 2014 and the effectiveness of the Company's internal control over financial reporting as of December 31, 2014 and all other procedures related to filing Astec's Annual Report on Form 10-K for the fiscal year ended December 31, 2014.

On January 9, 2015, the Audit Committee of Astec engaged KPMG LLP ("KPMG") as the new independent registered public accounting firm for Astec. During Astec's fiscal years ending December 31, 2013 and 2014, and the subsequent interim period from January 1, 2015 through January 9, 2015, Astec did not consult KPMG regarding (i) the application of accounting principles to a specific transaction, either completed or proposed, or the type of audit opinion that might be rendered on Astec's consolidated financial statements, or (ii) any matter that was the subject of a disagreement (as defined in Item 304(a)(1)(iv) of Regulation S-K) or any reportable event (as described in Item 304(a)(1)(v) of Regulation S-K).
