ALLURION TECHNOLOGIES, INC.

Item 1. Legal Proceedings.

From time to time, we may become involved in legal proceedings or be subject to claims arising in the ordinary course of our business. Except as described below, we are not currently a party to any material legal proceedings. Regardless of outcome, such proceedings or claims can have an adverse impact on us because of defense and settlement costs, diversion of resources and other factors, and there can be no assurances that favorable outcomes will be obtained.

On August 12, 2025, Vanderbilt University Medical Center (“Vanderbilt”) filed a complaint against us in the United States District Court for the Middle District of Tennessee, captioned Vanderbilt University Medical Center v. Allurion Technologies, Inc., d/b/a Allurion. Vanderbilt’s complaint alleges that we breached the Clinical Trial Agreement, dated June 30, 2022, by and between us and Vanderbilt, related to the clinical trial for the Allurion Balloon by failing to reimburse medical expenses incurred in treating a patient enrolled in such trial at Vanderbilt. Vanderbilt is seeking damages of approximately $2.5 million. We intend to defend against such claims vigorously, but we cannot be sure that we will be successful in prevailing in such proceeding or that it will not incur material costs in defending against such allegations.
