New in the latest 10-Q

4 paragraphs in the 10-Q filed Jun 3, 2026 with nothing like them in the 10-Q filed Mar 11, 2026 (at least half the words must differ; new numbers alone do not count). Quoted exactly, grouped by the item heading above them. This is text that changed, not a judgement of how serious it is.

The 10-Q's risk factors against the 10-K

Item 1A of the 10-Q filed Jun 3, 2026 against Item 1A of the 10-K filed Oct 8, 2025. A 10-Q repeats only the risks that changed, so a 10-K paragraph that is missing from it is not counted as removed. Added is a paragraph with nothing like it in the 10-K, Reworded a sentence that is in both with several words changed, Quiet changes a sentence in both where one to four words changed and one is a hedge or a modal (cut words struck through, new words highlighted and underlined). Text on the page, not a score; each links to the filing at sec.gov.

What the 10-Q itself says about its risk factors:
In addition to the other information set forth in the Quarterly Report on Form 10-Q, you should carefully consider the factors discussed in Part I, Item 1A, “Risk Factors” in our Annual Report on Form 10-K, for the fiscal year ended August 31, 2025. There have been no material changes in our risk factors from those disclosed in our Annual Report on Form 10-K.
