Forward-Looking Statements Disclosure

This Notification of Late Filing contains forward-looking statements within the meaning of the federal securities laws that reflect the Company's current views with respect to future events. Forward-looking statements contained in this notification are subject to the safe harbor created by the Private Securities Litigation Reform Act of 1995 and may be identified by words such as “expects,” “believes,” “intends,” “consistent,” or the negative versions thereof, and similar expressions and by the context in which they are used. Such forward-looking statements include statements about the filing of the Form 10-K and the financial statements contained therein and are based on the Company’s current expectations and speak only as of the date made. Such statements are highly dependent upon a variety of risks, uncertainties and other important factors that could cause actual results to differ materially from those reflected in such forward-looking statements. Such factors include, but are not limited to, the factors described under Part I, Item 1A. “Risk Factors” and elsewhere in our Annual Report on Form 10-K for the year ended August 26, 2023, Part II, Item 1A. “Risk Factors” and elsewhere in the Company’s subsequent Quarterly Reports on Form 10-Q and in the Company’s other filings with the Securities and Exchange Commission (the “SEC”).

See the Earnings Release for a comparison of the Company’s results of operations for fiscal 2024 compared to fiscal 2023. The results reported in the Earnings Release are preliminary and unaudited and are subject to change before the Company files the Form 10-K.
