Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On August 29, 2024, Allurion Technologies, Inc. (the “Company”) received written notice (the “Notice”) from the New York Stock Exchange (the “NYSE”) that it is not in compliance with the continued listing standard set forth in Section 802.01B of the NYSE’s Listed Company Manual (the “Minimum Market Capitalization Standard”) because the average market capitalization of the Company was less than $50.0 million over the consecutive 30 trading-day period ended August 29, 2024 and the Company’s last reported stockholders’ equity as of August 29, 2024 was less than $50.0 million. The Notice does not result in the immediate delisting of the Company’s common stock from the NYSE.

In accordance with applicable NYSE procedures, within 45 days from receipt of the Notice, the Company intends to submit a plan to the NYSE advising it of the definitive action(s) the Company has taken, is taking, or plans to take that would bring it into conformity with the Minimum Market Capitalization Standard within 18 months of receipt of the Notice (the “Cure Period”). Upon receipt of such plan, the NYSE will evaluate the plan and determine whether the Company has made a reasonable demonstration of its ability to come into conformity with the relevant listing standards within the Cure Period. If the NYSE accepts the Company’s plan, the NYSE will review the Company on a quarterly basis to confirm compliance with the plan. If the Company’s plan is not accepted, the Company fails to comply with the plan or does not meet the Minimum Market Capitalization Standard at the end of the Cure Period, it will be subject to NYSE’s prompt initiation of suspension and delisting procedures.

The Notice has no immediate impact on the listing of the Company’s common stock, which will continue to be listed and traded on the NYSE during such cure period, subject to the Company’s compliance with other NYSE continued listing standards. The Company’s common stock will continue to trade on the NYSE under the symbol “ALUR” with the designation of “.BC” to indicate the status of the shares as “below criteria.” If the Company does not regain compliance with the Minimum Market Capitalization Standard, the Company’s common stock will be subject to suspension and delisting from the NYSE. If the Company’s common stock ultimately were to be delisted, it could negatively impact the Company by reducing the liquidity and market price of the Company’s common stock. Furthermore, the Notice is not anticipated to impact the ongoing business operations of the Company or its reporting requirements with the U.S. Securities and Exchange Commission.

The Company had previously received a notice on August 12, 2024 that the Company was not in compliance with NYSE’s minimum average closing price listing requirement in Section 802.01A of the NYSE Listed Company Manual.

Cautionary Note Regarding Forward-Looking Statements

This Current Report on Form 8-K contains forward-looking statements within the meaning of the U.S. federal and state securities laws. These forward-looking statements generally are identified by the words “believe,” “project,” “expect,” “anticipate,” “estimate,” “intend,” “strategy,” “future,” “opportunity,” “plan,” “may,” “should,” “will,” “would,” “will be,” “will continue,” “will likely result,” and similar expressions and include statements regarding the Company’s plans to notify the NYSE that it intends to cure the market capitalization deficiency and return to compliance with the applicable NYSE continued listing standards, its intention to remain listed on the NYSE, and its options to regain compliance with the NYSE’s continued listing standards. Forward-looking statements are predictions, projections and other statements about future events that reflect the current beliefs and assumptions of the Company’s management based on information currently available to them and, as a result, are subject to risks and uncertainties. Many factors could cause actual future results or developments to differ materially from the forward-looking statements in this communication, including but not limited to (i) the ability of the Company to obtain and maintain regulatory approvals for and successfully commercialize its products and offerings, including the Allurion Balloon, (ii) the timing of, and results from, the Company’s clinical studies and trials, (iii) the evolution of the markets in which the Company competes, (iv) the ability of the Company to defend its intellectual property and satisfy regulatory requirements, (v) the impact of global economic conditions and geopolitical events on the Company’s business, (vi) the Company’s expectations regarding its market opportunities, (vii) the risk of economic downturns and a changing regulatory landscape in the highly competitive industry in which the Company operates, (viii) the risk that the Notice and noncompliance with NYSE continued listing standards may impact the Company’s results of operations, business operations and reputation and the trading prices and volatility of the Company’s common stock, and (ix) the Company’s ability to continue to meet NYSE continued listing standards. The foregoing list of factors is not exhaustive. You should carefully consider the foregoing factors and the other risks and uncertainties described in the “Risk Factors” section of the Company’s Annual Report on Form 10-K filed on March 26, 2024 (as subsequently amended) and other documents filed by the Company from time to time with the U.S. Securities and Exchange Commission. These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Forward-looking statements speak only as of the date they are made. Readers are cautioned not to put undue reliance on forward-looking statements, and the Company assumes no obligation and does not intend to update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise. The Company does not give any assurance that it will achieve its expectations.
