Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangement of Certain Officers

On September 30, 2025, Milena Alberti-Perez, a Class III member of the board of directors (the “Board”) of Allurion Technologies, Inc. (the “Company”), notified the Company of her resignation from the Board and her role as the chairperson of the Audit Committee of the Board (the “Audit Committee”), effective September 30, 2025. Ms. Alberti-Perez’s resignation was not the result of any disagreement with management or the Board or on any matter relating to the Company’s operations, policies or practices.

Ms. Alberti-Perez resigned to focus her time in the media sector, including a new position on the board of another public company in that sector. Such resignation and resulting reduction in the size of the Board aligns with the Board’s determination that a smaller board will improve efficiency and reduce director compensation costs. Effective upon Ms. Alberti-Perez’s resignation, the size of the Board will be reduced from nine to eight. The Board is currently evaluating which of its directors will replace Ms. Alberti-Perez as chairperson of the Audit Committee.
