This press release may contain certain statements relating to future results, which are forward-looking statements as that term is defined in the Private Securities Litigation Reform Act of 1995, reflecting management’s expectations about future conditions, including anticipated activities and benefits related to the acquisition. Forward-looking statements may also be identified because they contain words such as ‘‘anticipate,’’ ‘‘believe,’’ ‘‘continue,’’ ‘‘could,’’ ‘‘estimate,’’ ‘‘expect,’’ ‘‘intend,’’ ‘‘likely,’’ ‘‘may,’’ ‘‘might,’’ ‘‘plan,’’ ‘‘potential,’’ ‘‘predict,’’ ‘‘project,’’ ‘‘seek,’’ ‘‘should,’’ ‘‘target,’’ ‘‘will,’’ ‘‘would,’’ or similar expressions and the negatives of those terms. These forward-looking statements are based on beliefs of management, as well as assumptions and estimates based on information currently available to management and are subject to certain risks and uncertainties that could cause actual results to differ materially from historical results or those anticipated. For a discussion of these and other risks and uncertainties, refer to “Risk Factors” in AAR CORP.’s most recent Annual Report on Form 10-K and subsequent Quarterly Reports on Form 10-Q. Should one or more of these risks or uncertainties materialize adversely, or should underlying assumptions or estimates prove incorrect, actual results may vary materially from those described. These events and uncertainties are difficult or impossible to predict accurately and many are beyond management’s control. Management assumes no obligation to update any forward-looking statements to reflect events or circumstances after the date of such statements or to reflect the occurrence of anticipated or unanticipated events.
