Amendment Description	National Beverage Corp. (the “Company”) is filing this Amendment No. 1 on Form 10‑K/A (this “Amendment”) to its Annual Report on Form 10-K for the fiscal year ended April 29, 2023 (the “Form 10-K”), filed with the U.S. Securities and Exchange Commission (the “SEC”) on June 28, 2023, to provide certain information inadvertently omitted from Part I of Form 10-K.   As a result of a processing error by the third party responsible for the electronic transmission to the SEC, certain paragraphs of Item 1–Business (contained on pages 2 through 9) were not included in the Form 10-K. This Amendment revises Item 1 to include those paragraphs.   No changes have been made to the Form 10-K other than as described in the preceding paragraph. This Amendment does not reflect subsequent events occurring after the original filing date of the Form 10-K or modify or update in any way the financial statements, consents or any other items or disclosures contained therein. Accordingly, this Amendment should be read in conjunction with the Form 10-K and any subsequent filings with the SEC.
