This Form 8-K/A-1 amends Item 402(a) of the Form 8-K dated September 23, 2005 filed by August Technology Corporation on September 29, 2005.

Item 4.02(a) Non-Reliance on Previously Issued Financial Statements or a Related Audit Report or Completed Interim Review.

On September 28, 2005, the Company issued a press release announcing that the audit committee of the Company’s board of directors has determined to restate the timing of revenue recognized from a series of transactions with one customer. The Company therefore will restate its financial statements for the annual and quarterly periods in the fiscal year ended December 31, 2004 and the quarters ended March 31, 2005 and June 30, 2005 to reduce the net revenues in those periods by an aggregate of approximately $12.2 million. Accordingly, the financial statements for those periods should no longer be relied upon. A copy of the press release was attached to the initial Form 8-K filed on September 29, 2005 as Exhibit 99.1, and is incorporated herein by reference.

The Company will restate its financial statements by filing an amended Annual Report on Form 10-K/A for the year ended December 31, 2004 (including financial data for each quarter in 2004) and amended Quarterly Reports on Form 10-Q/A for the quarters ended March 31, 2005 and June 30, 2005 (including financial data for the comparable quarters of 2004). The Company currently expects to file the amended reports in conjunction with the filing of the Company’s Quarterly Report on Form 10-Q for the quarter ended September 30, 2005, currently planned for November 9, 2005.

The Audit Committee has discussed with KPMG LLP, the Company’s independent registered public accounting firm, the matters disclosed in this Current Report on Form 8-K pursuant to this Item 4.02(a).
