Item 2.02 — Results of Operations and Financial Condition

On May 30, 2007, Powell Industries, Inc. (NASDAQ: POWL) held a conference call to discuss the results of its fiscal 2007 second quarter ended March 31, 2007, as reflected in the attached press release dated May 30, 2007 released earlier that day. The Company changed its fiscal year end from October 31 to September 30 effective September 30, 2006. Prior year financial statements have not been restated to conform to the new fiscal year as the Company’s operations do not fluctuate on a seasonal basis and the change in fiscal year end is only 31 days.

Readers are cautioned that such forward-looking statements involve risks and uncertainties in that actual results may differ materially from those projected in the forward-looking statements. In the course of operations, the Company is subject to certain risk factors, including but not limited to competition and competitive pressures, sensitivity to general economic and industrial conditions, international political and economic risks, availability and price of raw materials and execution of business strategy. The information in this Current Report is being furnished pursuant to Item 2.02, Results of Operations and Financial Condition. Pursuant to general instruction B.2. of Form 8-K, the information in this Current Report shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934 or otherwise subject to the liabilities of that Section.
