Meeting to Now be Held on Thursday, April 10, 2025 at 12:00 pm Via Live Audio Webcast

Allurion Technologies, Inc. ("Allurion" or the "Company") (NYSE:ALUR), a company dedicated to ending obesity, today announced that its Special Meeting of Stockholders (the "Special Meeting"), originally scheduled for Friday, April 4, 2025, has been postponed. The Special Meeting is now scheduled to be held on Thursday, April 10, 2025 at 12:00 p.m. (Eastern Time) and will still be held virtually via live audio webcast at www.virtualshareholdermeeting.com/ALUR2025SM.

The record date for the Special Meeting, March 14, 2025, remains unchanged and applies to the postponed Special Meeting.

The Special Meeting has been postponed to allow for further time to solicit proxies from the Company's stockholders and provide stockholders with additional time to vote in order to facilitate broader participation.

Stockholders who have already cast their votes do not need to take any action, unless they wish to change or revoke their prior proxy or voting instructions, and their votes will be counted at the postponed Special Meeting. For stockholders who have not yet cast their votes, we urge them to vote their shares now, so they can be tabulated prior to the postponed Special Meeting.

The Company's Board of Directors unanimously recommends that you vote FOR the proposals identified in the Company's Definitive Proxy Statement for the Special Meeting.

Important Additional Information

Information with respect to the proposals to be considered at the Special Meeting and instructions on how to vote can be found in the Definitive Proxy Statement filed by the Company with the U.S. Securities and Exchange Commission on March 24, 2025 with respect to the Special Meeting. STOCKHOLDERS ARE URGED TO READ THE PROXY STATEMENT (INCLUDING ANY AMENDMENTS OR SUPPLEMENTS THERETO) FILED BY THE COMPANY AND ANY OTHER RELEVANT DOCUMENTS FILED WITH THE SEC CAREFULLY AND IN THEIR ENTIRETY BECAUSE THEY CONTAIN OR WILL CONTAIN IMPORTANT INFORMATION ABOUT ANY SOLICITATION. Stockholders may obtain a copy of the Proxy Statement at the SEC's web site www.sec.gov or on the "Financials - SEC Filings" section of Allurion's website at investors.allurion.com/financials/sec-filings.

The Company urges stockholders to please consider the issues presented in the Definitive Proxy Statement for the Special Meeting and promptly vote the stockholder's shares to ensure that such shares are represented at the Special Meeting. Submitting a proxy now will not prevent a stockholder from voting the stockholder's shares at the postponed Special Meeting if the stockholder desires to do so, as a proxy is revocable at the stockholder's option.
