Forward-looking statements include statements about our future and statements that are not historical facts. These forward-looking statements are typically identified by such words as “believe,” “expect,” “anticipate,” “may,” “intend,” “outlook,” “will,” “estimate,” “forecast,” “project,” “should,” and other similar words and expressions, and are subject to numerous assumptions, risks and uncertainties, which will change over time.

Forward-looking statements also include statements pertaining to our strategies for future development of our businesses and products. Forward-looking statements speak only as of the date they are made; we do not assume any duty, and do not undertake, to update any forward-looking statements.

Information regarding important factors, including risk factors that could cause actual results or outcomes to differ, perhaps materially, from those in our forward-looking statements, is contained in reports we file with the SEC, including our Quarterly Report on Form 10-Q for the quarter ended August 31, 2025. You should read and interpret any forward-looking statement together with reports we file or furnish with the SEC. Past performance may not be indicative of future results. Different types of investments involve varying degrees of risk. Therefore, it should not be assumed that future performance of any specific investment or investment strategy will be profitable or equal the corresponding indicated performance level(s).
