To our Stockholders:

American Electric Technologies, Inc. is pleased to provide proxy materials for the 2009 Annual Meeting on the Internet instead of mailing printed copies. This allows us to provide our stockholders with the information they need, while lowering the cost of the delivery of the proxy materials and reducing the environmental impact of printing and mailing hard copies.

Our Stockholders of Record must request a copy of the Proxy Card in order to vote without attending the Annual Meeting. You will receive an Important Notice Regarding the Availability of Proxy Materials on or about March 27, 2009. This Notice will contain an Account Number which you should have available when ordering proxy material.

The 2009 Annual Meeting will be held Thursday, May 7, 2009 at 1:00 p.m. at the principal office of the Company, 6410 Long Drive, Houston, Texas. Stockholders as of the close of business on March 4, 2009 are entitled to vote at the Annual Meeting.
