Amendment Description This Amendment No. 1 on Form 10-K/A (the “Amendment”) amends the Annual Report on Form 10-K (the “2023 Form 10-K”) of CLS Holdings USA, Inc. (the “Company”) for the fiscal year ended May 31, 2023 (the “2023 Fiscal Year”), as filed with the Securities and Exchange Commission (the “SEC”) on August 24, 2023. We are filing this Amendment to amend Part III of the 2023 Form 10-K to include the information required by and not included in Part III of the 2023 Form 10-K because we did not file our definitive proxy statement within 120 days of the end of the 2023 Fiscal Year. Because no financial statements are contained within this Amendment, we are not filing currently dated certifications pursuant to Section 906 of the Sarbanes-Oxley Act of 2002. Except as described above, no other changes have been made to the 2023 Form 10-K. The 2023 Form 10-K continues to speak as of the date of the 2023 Form 10-K, and we have not updated the disclosures contained therein to reflect any events which occurred at a date subsequent to the filing of the 2023 Form 10-K other than as expressly indicated in this Amendment.
