Cautionary Note Regarding Forward-Looking Statements; Available Information

This proxy statement includes estimates, projections, statements relating to our business plans, initiatives, objectives, and expected operating results that are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Forward-looking statements may appear throughout this proxy statement. These forward-looking statements can generally be identified by phrases such as “expects,” “anticipates,” “believes,” “estimates,” “future,” “intends,” “may,” “plans to,” “ought,” “could,” “will,” “should,” “likely,” “appears,” “projects,” “forecasts,” “outlook” or other similar words or phrases, as well as by discussions of strategy, plans, or intentions. Our forward-looking statements are based on management’s expectations and beliefs as of the date of this proxy statement. Although we believe that our expectations are reasonable, we can give no assurance that these expectations will prove to have been correct, and actual results may vary materially. We describe risks and uncertainties that could cause actual results and events to differ materially in our filings with the U.S. Securities and Exchange Commission (the “SEC”), including, but not limited to, in Part I, Item 1A, “Risk Factors” of our Annual Report on Form 10-K for the fiscal year ended August 31, 2025. We undertake no obligation to update or revise publicly any forward-looking statements, whether because of new information, future events, or otherwise.
