All statements at the conference (including Exhibit 99.1), other than historical financial information, may be deemed “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Words such as “expects”, “anticipates”, “intends”, “plans”, “believes”, “seeks”, “estimates”, “should”, “will”, and variations of such words and similar expressions are intended to identify such forward-looking statements. These statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions, which are difficult to predict. Therefore, actual outcomes and results may differ materially from what is expressed or forecasted in such forward-looking statements. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date on which they are made. We undertake no obligations to update publicly any forward-looking statements, whether as a result of new information, future events or otherwise. Important factors that could cause results to differ materially from those in the forward-looking statements include (1) the timing and extent of changes in raw material and component prices, (2) the effects of fluctuations in the commercial/industrial new construction market, (3) the timing and extent of changes in interest rates, as well as other competitive factors during the year, and (4) general economic, market or business conditions. For a discussion of such risks and uncertainties, which could cause actual results to differ from those contained in any forward-looking statements, see “Risk Factors” and “Forward Looking Statements” in AAON’s Annual Report on Form 10-K for the most recent fiscal year, as may be revised and updated by AAON’s Quarterly Reports on Form 10-Q, and AAON’s Current Reports on Form 8-K.

In accordance with General Instruction B.2 of Form 8-K, the information in this Item (including Exhibit 99.1) shall not be deemed "filed" for the purpose of Section 18 of the Securities Exchange Act of 1934, as amended, nor shall it be deemed incorporated by reference in any filing.
