Amendment Description	Explanatory NoteAllurion Technologies, Inc. (the "Company" or "Allurion") is filing this Amendment No. 1 on Form 10-K/A (this "Amendment No. 1") to its Annual Report on Form 10-K for the fiscal year ended December 31, 2023, which was filed with the Securities and Exchange Commission on March 26, 2024 (the "Original Form 10-K"), for the sole purpose of including the information required by Part III of Form 10-K. This information was previously omitted from the Original Form 10-K in reliance on General Instruction G(3) to Form 10-K, which permits the information required by Part III to be incorporated by reference from our definitive proxy statement if such proxy statement is filed no later than 120 days after our fiscal year-end. We are filing this Amendment No. 1 to include Part III information in our Annual Report on Form 10-K because we will not file a definitive proxy statement containing this information within 120 days after the end of the fiscal year covered by the Original Form 10-K. Pursuant to Rule 12b-15 under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), this Amendment No. 1 also contains certifications pursuant to Section 302 of the Sarbanes-Oxley Act of 2002, which are attached hereto. Because no financial statements have been included in this Amendment No. 1, and this Amendment No. 1 does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4, and 5 of the certifications have been omitted.Except as explicitly set forth herein, this Amendment No. 1 does not purport to modify or update the disclosures in, or exhibits to, the Original Form 10-K or update the Original Form 10-K to reflect events occurring after the date of such filing.
