Record Date and Outstanding Shares

Holders of record of shares of our common stock, $0.0001 par value per share (the "common stock"), as of the close of business on November 6, 2024 (the "Record Date"), will be entitled to notice of and to vote at the Annual Meeting and any postponement or adjournment thereof.

As of the Record Date, there were _________ shares of common stock outstanding and entitled to vote at the Annual Meeting. Each share of common stock is entitled to one vote on any matter presented to stockholders at the Annual Meeting. The shares of common stock are the only voting securities of the Company.

Proposals

At the Annual Meeting, our stockholders will be asked:

1.
To elect Shantanu Gaur, Krishna Gupta and Nicholas Lewin as Class I Directors to serve until the Company's 2027 Annual Meeting of Stockholders, and until their respective successors shall have been duly elected and qualified or until their earlier death, resignation or removal (the "Director Election Proposal" or "Proposal 1");

1

6.
To approve an adjournment of the Annual Meeting, if necessary, to permit further solicitation and vote of proxies in the event that there are insufficient votes in favor of Proposals 2, 3 and 4 (the "Adjournment Proposal" or "Proposal 6").

Recommendations of the Board and Proxies

The Board recommends that you vote your shares as indicated below:

FOR the election of Shantanu Gaur, Krishna Gupta and Nicholas Lewin as Class I Directors;
FORthe Reverse Stock Split Proposal;
FOR the Note Shares Issuance Proposal;
FOR the Private Placement Shares Issuance Proposal;
FOR the Auditor Ratification Proposal; and
FOR the Adjournment Proposal, if necessary.

If you return a properly completed proxy card, or vote your shares by telephone or Internet, your shares of common stock will be voted on your behalf as you direct. If you return a signed and dated proxy card or otherwise vote without marking voting selections, your shares will be voted in accordance with the recommendations of the Board set forth above.

Any stockholder may revoke a proxy at any time prior to the Annual Meeting by signing and submitting a later-dated proxy or a written notice of revocation to the Secretary of the Company, or by granting a subsequent proxy through the Internet or telephone. Stockholders attending the Annual Meeting may also revoke their proxies by voting online at the Annual Meeting. Attendance at the Annual Meeting will not itself be deemed to revoke a proxy unless a stockholder gives affirmative notice at the Annual Meeting that such stockholder intends to revoke the proxy and vote online. If a stockholder's shares are held in street name, such holder may change or revoke voting instructions by following the specific directions provided by the stockholder's bank or broker. See "Can I change my vote after I submit my proxy?" below.

Quorum and Adjournment; Abstentions, Votes Withheld and Broker Non-Votes

The presence by remote communication (i.e., online) or by proxy of the holders of a majority in voting power of the shares of common stock issued and outstanding on the Record Date and entitled to vote is required to constitute a quorum at the Annual Meeting.

The stockholders that are present online or represented by proxy at the Annual Meeting may adjourn the meeting from time to time for any reason, regardless of whether a quorum is present. If the Annual Meeting is adjourned to another time, date or place (including an adjournment taken to address a technical failure to convene or continue a meeting using remote communication), notice is not required to be given of the adjourned meeting if the time, place (if any), and the means of remote communication by which stockholders and proxy holders may attend and participate at such adjourned meeting are announced at the Annual Meeting, displayed on the same electronic network used to enable stockholders and proxy holders to participate in the meeting by means of remote communication during the time scheduled for the Annual Meeting, or as set forth in the Notice of Annual Meeting. However, if the adjournment is for more than 30 days from the original meeting date, or if after the adjournment a new record date is fixed for the adjourned meeting, notice of the adjourned meeting and the means of remote communication, if any, will be given to each stockholder of record entitled to vote and each stockholder who, by law or under the Company's organizational documents, is entitled to such notice.

At any adjourned Annual Meeting at which a quorum is present, any business may be transacted that might have been transacted at the Annual Meeting as originally scheduled.

Abstentions, votes withheld and broker non-votes will count in determining whether a quorum is present at the Annual Meeting and any adjourned meeting. A broker non-vote occurs if the broker or other nominee who holds shares represented by a proxy has not received instructions with respect to a particular proposal and does not have discretionary authority with respect to such proposal. Under the rules that govern brokers who are voting shares held in street name, brokers have the discretion to vote those shares on routine matters but not on non-routine matters. Proposals 1, 3, 4 and 6 are considered to be "non-routine" under these rules, such that your broker may not vote your shares on those proposals in the absence of your voting instructions.

2

Conversely, Proposals 2 and 5 are considered to be "routine" matters under these rules and thus if you do not return voting instructions to your broker by its deadline, your shares may be voted by your broker in its discretion on Proposals 2 and 5.

The votes required, and the treatment of abstentions, votes withheld and broker non-votes, for each matter to be voted on at the Annual Meeting are set forth in "How many votes are required for the approval of the proposals to be voted upon and how will votes withheld, abstentions and broker non-votes be treated?"below.

Other Matters

We know of no other business that will be presented at the Annual Meeting. If any other matter properly comes before the stockholders for a vote at the Annual Meeting, the proxy holders named on the Company's proxy card will vote your shares in accordance with their best judgment and consistent with applicable law.

No director or executive officer of the Company since the beginning of the last fiscal year, or nominee for director, nor any associate of any of the foregoing, has any substantial interest, direct or indirect, by security holdings or otherwise, in any matter to be acted upon at the Annual Meeting.

QUESTIONS AND ANSWERS ABOUT THE 2024 ANNUAL MEETING OF STOCKHOLDERS

Why am I receiving this Proxy Statement?

You have received these proxy materials because our Board is soliciting your proxy to vote your shares at the Annual Meeting. This Proxy Statement includes information that we are required to provide to you under the rules of the U.S. Securities and Exchange Commission ("SEC") and is designed to assist you in voting your shares.

Who is entitled to vote at the Annual Meeting?

The Record Date for the Annual Meeting is November 6, 2024. You are only entitled to vote at the Annual Meeting if you were a stockholder of record at the close of business on the Record Date, or if you hold a valid proxy for the Annual Meeting. Each outstanding share of common stock is entitled to one vote for all matters before the Annual Meeting. At the close of business on the Record Date, there were ___________ shares of common stock outstanding and entitled to vote at the Annual Meeting.

A list of our stockholders of record will be open for examination by any stockholder beginning ten days prior to the Annual Meeting at our headquarters located at 11 Huron Drive, Natick, MA 01760. If you would like to view the list, please contact our Corporate Secretary to schedule an appointment by emailing [email protected] or writing to such officer at the address above. In addition, the list will be available for inspection by stockholders on the virtual meeting website during the Annual Meeting.

What is the difference between being a "record holder" and holding shares in "street name"?

A record holder holds shares in such holder's name. Shares held in "street name" are held in the name of a bank or brokerage firm on a person's behalf.

Am I entitled to vote if my shares are held in "street name"?

Yes. If your shares are held by a bank or a brokerage firm, you are considered the "beneficial owner" of those shares held in "street name." If your shares are held in street name, these proxy materials are being provided to you by your bank or brokerage firm, along with a voting instruction card included with the printed copies of our proxy materials. As the beneficial owner, you have the right to direct your bank or brokerage firm on how to vote your shares, and the bank or brokerage firm is required to vote your shares in accordance with your instructions. You are also invited to attend the Annual Meeting via the internet at www.virtualshareholdermeeting.com/ALUR2024. However, because you are not the stockholder of record, you may not vote your shares live online at the Annual Meeting unless you request and obtain a valid proxy from your broker or other agent.

How many shares must be present to hold the Annual Meeting?

A quorum must be present at the Annual Meeting for any business to be conducted. The presence at the Annual Meeting online or by proxy of the holders of a majority in voting power of the issued and outstanding shares of our common stock entitled to vote on the Record Date will constitute a quorum for the Annual Meeting.

Who can attend the Annual Meeting?

If you are a stockholder of record or a beneficial owner as of the Record Date, you may attend and participate in the Annual Meeting by visiting the following website: www.virtualshareholdermeeting.com/ALUR2024. To attend and participate in the Annual Meeting, you will need the 16-digit control number included on your proxy card or on the instructions that accompanied your proxy materials. If your shares are held in "street name," you should contact your bank or broker to obtain your 16-digit control number or otherwise vote through the bank or broker. If you lose your 16-digit control number, you may join the Annual Meeting as a "Guest" but you will not be able to vote, ask questions or access the list of stockholders as of the Record Date. The meeting webcast will begin promptly at 12:00 p.m. Eastern Time. We encourage you to access the meeting prior to the start time. Online check-in will begin at 11:45 a.m. Eastern Time, and you should allow ample time for the check-in procedures.

What if a quorum is not present at the Annual Meeting?

If a quorum is not present at the scheduled time of the Annual Meeting, the Chairperson of the Annual Meeting is authorized by our Amended and Restated Bylaws (our "Bylaws") to adjourn the meeting, without the vote of stockholders.

What does it mean if I receive more than one set of proxy materials?

It means that your shares are held in more than one account at the transfer agent and/or with banks or brokers. Please vote all of your shares. To ensure that all of your shares are voted, for each set of proxy materials, please submit your proxy by phone, via the Internet, or by signing, dating and returning the proxy card provided in the enclosed envelope.

Stockholders of Record.

Internet and telephone voting facilities for stockholders of record will be made available 24 hours a day and will close at 11:59 p.m., Eastern Time, on Tuesday, December 10, 2024.

Whether or not you expect to attend the Annual Meeting online, we urge you to vote your shares as promptly as possible to ensure your representation. If you submit your proxy, you may still decide to attend the Annual Meeting and vote your shares electronically.

Beneficial Owners of Shares Held in "Street Name."

If your shares are held in "street name" through a bank or brokerage firm, you will receive instructions on how to vote from the bank or broker. You must follow the bank's or broker's instructions in order for your shares to be voted. Internet and telephone voting also may be offered to stockholders owning shares through certain banks and brokers. If your shares are not registered in your own name and you would like to vote your shares online at the Annual Meeting, you should contact your bank or broker to obtain your 16-digit control number or otherwise vote through the bank or broker. If you lose your 16-digit control number, you may join the Annual Meeting as a "Guest," but you will not be able to vote, ask questions or access the list of stockholders as of the Record Date.

Can I change my vote after I submit my proxy?

Yes.

If you are a registered stockholder, you may revoke your proxy and change your vote:

by submitting a duly executed proxy bearing a later date;
by granting a subsequent proxy through the Internet or telephone;
by giving written notice of revocation to the Secretary of the Company prior to or at the Annual Meeting; or
by voting online at the Annual Meeting.

Your most recent proxy card or Internet or telephone proxy is the vote that is counted. Your attendance at the Annual Meeting by itself will not revoke your proxy unless you give written notice of revocation to the Secretary before your proxy is voted or you vote online at the Annual Meeting.

If your shares are held in street name, you may change or revoke your voting instructions by following the specific directions provided to you by your bank or broker, or you may vote online at the Annual Meeting using your 16-digit control number or otherwise voting through your bank or broker.

Who will count the votes?

A representative of Broadridge Financial Solutions, Inc., our inspector of election, will tabulate and certify the votes.

What if I do not specify how my shares are to be voted?

If you submit a proxy but do not indicate any voting instructions, the persons named as proxies will vote in accordance with the recommendations of the Board. The Board's recommendations are indicated on page 2 of this Proxy Statement, as well as with the description of each proposal in this Proxy Statement.

5

Will any other business be conducted at the Annual Meeting?

We know of no other business that will be presented at the Annual Meeting. If any other matter properly comes before the stockholders for a vote at the Annual Meeting, the proxy holders named on the Company's proxy card will vote your shares in accordance with their best judgment and consistent with applicable law.

What if I have technical difficulties or trouble accessing the virtual meeting website?

We will have technicians ready to assist you with any technical difficulties you may have accessing the virtual meeting website, and the information for assistance will be located on www.virtualshareholdermeeting.com/ALUR2024.

How many votes are required for the approval of the proposals to be voted upon and how will votes withheld, abstentions and broker non-votes be treated?

Proposal

Votes Required

Effect of

Votes Withheld,
Abstentions and Broker Non-Votes

Proposal 1:

Director Election Proposal

The plurality of the votes properly cast. The three nominees receiving the highest number of affirmative "FOR" votes will be elected as Class I Directors.

Votes withheld and broker non-votes will have no effect.

Proposal 2:

Reverse Stock Split Proposal

The affirmative vote of the holders of a majority of the outstanding shares of capital stock entitled to vote thereon.

Abstentions and broker non-votes will count as votes against.

Proposal 3:

Note Shares Issuance Proposal

The affirmative vote of the holders of a majority of the votes properly cast.

Abstentions and broker non-votes will have no effect.

Proposal 4:

Private Placement Shares Issuance Proposal

The affirmative vote of the holders of a majority of the votes properly cast.

Abstentions and broker non-votes will have no effect.

Proposal 5:

Auditor Ratification Proposal

The affirmative vote of the holders of a majority of the votes properly cast.

Abstentions and broker non-votes will have no effect.

Proposal 6:

Adjournment Proposal

The affirmative vote of the holders of a majority of the votes properly cast.

Abstentions and broker non-votes will have no effect.

What is a "vote withheld" and an "abstention" and how will votes withheld and abstentions be treated?

A "vote withheld," in the case of the proposal regarding the election of directors, or an "abstention," in the case of the proposals regarding approval of the Reverse Stock Split, the Note Shares Issuance, the Private Placement Shares Issuance, the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm and adjournment of the Annual Meeting (if necessary), represents a stockholder's affirmative choice to decline to vote on a proposal. Votes withheld and abstentions are counted as present and entitled to vote for purposes of determining a quorum. Votes withheld have no effect on the election of directors. Abstentions have the same effect as a vote "AGAINST" Proposal 2. Abstentions have no effect on Proposals 3, 4, 5 and 6.

6

What are broker non-votes and do they count for determining a quorum?

Generally, broker non-votes occur when shares held by a broker in "street name" for a beneficial owner are not voted with respect to a particular proposal because the broker (i) has not received voting instructions from the beneficial owner and (ii) lacks discretionary voting power to vote those shares. Proposals 1, 3, 4 and 6 are considered to be "non-routine" under these rules, such that your broker may not vote your shares on those proposals in the absence of your voting instructions. Conversely, Proposals 2 and 5 are considered to be "routine" matters under these rules and thus if you do not return voting instructions to your broker by its deadline, your shares may be voted by your broker in its discretion on Proposals 2 and 5. Broker non-votes count for purposes of determining whether a quorum is present.

Where can I find the voting results of the Annual Meeting?

We plan to announce preliminary voting results at the Annual Meeting and we will report the final results in a Current Report on Form 8-K, which we intend to file with the SEC after the Annual Meeting. After the Form 8-K is filed, you may obtain a copy by visiting the investor relations section of our website at investors.allurion.com or by writing to Allurion Technologies, Inc., 11 Huron Drive, Natick, MA 01760, Attention: Corporate Secretary.

two independent directors nominated by the Company, one of which shall be designated by RTW Investments, LP ("RTW"), which is currently Nicholas Lewin, and the other of which is currently Milena Alberti-Perez.

Pursuant to the Note Purchase Agreement, dated April 14, 2024, by and among the Company, RTW, as agent for the purchasers (the "Purchasers") party thereto from time to time (RTW in such capacity, the "Principal Purchaser") and Acquiom Agency Services LLC as collateral agent for the Purchasers and Principal Purchaser, as amended on April 16, 2024 (as amended, the "Note Purchase Agreement'), we agreed to include an additional director nominee in our proxy statement for the Annual Meeting, which additional nominee would go through our director nomination process, as described below, and RTW was granted the right to approve such nominee. In September 2024, we appointed Keith B. Johns II to our Board as a Class III director and RTW approved his appointment in satisfaction of such obligations.

Our Charter and our Bylaws provide that, subject to the rights of any outstanding series of preferred stock of the Company to elect directors, the authorized number of directors is fixed, and may be changed from time to time, solely by the Board. Subject to the rights, if any, of the holders of any outstanding series of preferred stock of the Company to elect directors, when the number of directors is increased or decreased, the Board shall determine the class or classes to which the increased or decreased number of directors shall be apportioned, although no decrease in the number of directors may shorten the term of any incumbent director.

The division of our Board into three classes with staggered three-year terms may delay or prevent a change in control of our Company. Subject to the rights of any outstanding series of preferred stock of the Company to elect and remove directors, our directors may be removed only for cause by the affirmative vote of the holders of not less than two-thirds of our outstanding voting stock entitled to vote in the election of directors.

Each of the nominees has agreed to be named in this Proxy Statement and to serve if elected. We believe that all of the nominees will be able and willing to serve if elected. However, if any nominee should become unable or unwilling to serve for any reason, proxies may be voted for another person nominated as a substitute by our Board or our Board may reduce the number of directors.

Vote Required

The proposal regarding the election of directors requires the approval of a plurality of the votes cast. The three nominees receiving the highest number of affirmative "FOR" votes will be elected as Class I Directors. Votes withheld and broker non-votes are not considered to be votes cast and, accordingly, will have no effect on the outcome of the vote on this proposal.

The Board of Directors unanimously recommends a vote FOR

the election of each of the Class I Director nominees.

PROPOSAL 2: REVERSE STOCK SPLIT PROPOSAL

Overview

The Board has approved and declared advisable, and is asking stockholders to consider and vote upon, an amendment to our Charter to combine the outstanding shares of our common stock into a lesser number of outstanding shares, otherwise known as a "reverse stock split," with the exact ratio and effective time of such Reverse Stock Split to be determined by our Board, subject to the limitations described below.

If approved by our stockholders at the Annual Meeting, the Board would have the sole discretion to effect the Reverse Stock Split at any time within one year of such approval, and to fix the specific ratio for the Reverse Stock Split within the range of not less than 1-for-10 and not more than 1-for-25.

The Reverse Stock Split, if approved by our stockholders, would become effective upon the filing with the Secretary of State of the State of Delaware of a Certificate of Amendment to our Charter setting forth the Reverse Stock Split (the "Certificate of Amendment"), or at a later time if and as set forth in the Certificate of Amendment. The exact timing will be determined by the Board based on its evaluation as to when such action will be the most advantageous to the Company and our stockholders. In addition, the Board reserves the right, notwithstanding stockholder approval, to abandon the Reverse Stock Split if, at any time prior to the effectiveness of the Reverse Stock Split, the Board, in its sole discretion, determines that it is no longer in the best interests of the Company and our stockholders to proceed. No further action on the part of stockholders will be required to either implement or abandon the Reverse Stock Split.

The proposed form Certificate of Amendment to our Charter to effect the Reverse Stock Split is attached as Appendix A to this Proxy Statement. Any amendment to our Charter to effect the Reverse Stock Split will include the ratio fixed by the Board within the range approved by our stockholders.

As of November 6, 2024, a total of __________ shares of our common stock were issued and outstanding and no shares were held in treasury. Based on such number of shares of our common stock issued and outstanding, immediately following the effectiveness of the Reverse Stock Split (and without giving any effect to the treatment of fractional shares), we will have, depending on the reverse stock split ratio selected by our Board, issued and outstanding shares of common stock as illustrated in the table under the heading "Impact on Common Stock" below.

The Reverse Stock Split will not result in a reduction of the total number of shares of our common stock that the Company is authorized to issue by a corresponding ratio, and, as a result, the number of authorized shares of common stock available for issuance will increase. See "Risks Associated with the Reverse StockSplit" below.

All holders of our common stock will be affected proportionately by the Reverse Stock Split. Each stockholder will hold the same percentage of the outstanding common stock immediately following the Reverse Stock Split as that stockholder did immediately prior to the Reverse Stock Split, except to the extent that the Reverse Stock Split results in stockholders receiving additional shares as a result of rounding up fractional shares.

Reasons for Reverse Stock Split

NYSE Listing Standards and Non-Compliance Notices

Our primary objective in effectuating the Reverse Stock Split is to raise the trading price of our common stock to meet the NYSE's continued listing standards. Under Section 802.01C of the NYSE's Listed Company Manual ("Section 802.01C"), a company is considered below compliance standards if the average closing price of its listed security as reported by the NYSE is less than $1.00 over a consecutive 30 trading-day period.

On August 12, 2024, the Company received written notice (the "Closing Price Notice") from the NYSE that it was not in compliance with Section 802.01C because the average closing price of the common stock was less than $1.00 per share over the consecutive 30 trading-day period ended August 8, 2024. The Closing Price Notice did not have an immediate impact on the listing of the common stock, which will continue to be listed and traded on the NYSE during a cure period as described below, subject to the Company's compliance with other NYSE continued listing standards.

On August 29, 2024, the Company also received written notice (the "Market Cap Notice") from 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

13

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 Market Cap Notice also did not result in the immediate delisting of the common stock from the NYSE, and the Company plans to remediate this deficiency as described more fully below.

On October 25, 2024, the closing price for our common stock on the NYSE was $0.76 per share.

Plan to Regain Compliance

The Company can regain compliance with Section 802.01C at any time within a six-month cure period following its receipt of the Closing Price Notice (the "Minimum Cure Period") if, on the last trading day of any calendar month during such Minimum Cure Period, the Company has both: (i) a closing share price of at least $1.00, and (ii) an average closing share price of at least $1.00 over the 30 trading-day period ending on the last trading day of the applicable calendar month. The Company is pursuing the Reverse Stock Split in order to regain compliance with this listing standard in the event of stockholder approval of this Proposal 2. If the Company does not regain compliance with the minimum share price requirement within the Minimum Cure Period, the common stock will be subject to suspension and delisting from the NYSE.

In accordance with applicable NYSE procedures, within 45 days from receipt of the Market Cap Notice, the Company must submit a plan to the NYSE advising it of the definitive action(s) the Company has taken, is taking, and/or plans to take that would bring it into conformity with the Minimum Market Capitalization Standard within 18 months of receipt of the Market Cap Notice (the "Market Cap 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 Market Cap 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 the Company does not meet the Minimum Market Capitalization Standard at the end of the Market Cap Cure Period, it will be subject to NYSE's prompt initiation of suspension and delisting procedures. The Company submitted its plan to regain compliance on October 11, 2024.

Consequences of Compliance Failure

Failure to approve the Reverse Stock Split may have serious adverse effects on the Company and its stockholders. Our common stock could be delisted from the NYSE because shares of our common stock may continue to trade below the requisite $1.00 per share price needed to comply with the continued listing standards of the NYSE and maintain our listing. Our shares may then be quoted on the Pink Sheets or other small trading markets, which are generally considered to have less volume and be less efficient markets. We believe an investor likely would find it less convenient to sell, or to obtain accurate quotations in seeking to buy, our common stock on an over-the-counter market. Many investors likely would not buy or sell our common stock at all due to difficulty in accessing over-the-counter markets, policies preventing them from trading in securities not listed on a national exchange, or other reasons. In that event, our common stock could trade thinly as a microcap or penny stock, adversely decrease to nominal levels of trading, and may be avoided by retail and institutional investors, resulting in the impaired liquidity of the stock.

The Reverse Stock Split, if effected, should have the immediate effect of increasing the price of our common stock as reported on the NYSE, therefore reducing the risk that our common stock could be delisted. However, we cannot assure you that the price of our common stock will not decline after the Reverse Stock Split. Other factors, such as our financial results, market conditions and the market perception of our business, may adversely affect the per share trading price of our common stock following the Reverse Stock Split. Under proposed NYSE rules, if the price of our common stock fails to satisfy the $1.00 minimum price requirement for a consecutive 30 trading-day period within one year after effectiveness of the Reverse Stock Split, then the common stock would be subject to delisting by the NYSE without any opportunity for a cure period.

Our Board believes that the Reverse Stock Split is necessary to maintain our listing on the NYSE in the absence of an improvement in the trading price based on business conditions or other catalysts. Accordingly, the Board approved the Reverse Stock Split, subject to stockholder approval, and directed that this Proposal 2 be submitted to our stockholders for approval at the Annual Meeting, including for the reasons discussed below.

Other Potential Benefits of the Reverse Stock Split

Appeal to a Broader Range of Investors to Generate Greater Investor Interest

We believe that the low market price of our common stock impairs its acceptability to important segments of the institutional investor community and the investing public. An increase in our stock price may make our common stock more

14

attractive to investors. Brokerage firms may be reluctant to recommend lower-priced securities to their clients. Many institutional investors have policies prohibiting or discouraging them from holding lower-priced stocks in their portfolios, which reduces the number of potential purchasers of our common stock. Investment funds also may be reluctant to invest in lower-priced stocks. Investors may also be dissuaded from purchasing lower-priced stocks because the brokerage commissions, as a percentage of the total transaction, tend to be higher for such stocks.

Moreover, the analysts at many brokerage firms do not monitor the trading activity or otherwise provide coverage of lower-priced stocks. The trading market for our common stock depends, in part, on the research and reports that securities and industry analysts publish about us and our business. If few or no securities or industry analysts cover us, or current analysts cease coverage due to our share price, demand and the trading price for our common stock would likely be negatively impacted. Giving the Board the ability to effect the Reverse Stock Split, and thereby increase the price of our common stock, would give the Board the ability to address these issues if it is deemed necessary.

Improved Perception of Our Common Stock as an Investment Security

The Board believes that effecting the Reverse Stock Split is one potential means of increasing the share price of our common stock to improve the perception of our common stock as a viable investment security. Lower-priced stocks have a perception in the investment community as being risky and speculative, which may negatively impact not only the price of our common stock, but also our market liquidity. In the event the Reverse Stock Split increases the trading price of our common stock, it may have the effect of improving this negative perception and market liquidity.

Risks Associated with the Reverse Stock Split

There are risks associated with the Reverse Stock Split, including that the Reverse Stock Split may not result in an increase in the trading price of our common stock. Reducing the number of outstanding shares of our common stock through a Reverse Stock Split is intended, absent other factors, to increase the per share market price of our common stock. However, other factors, such as our financial results, market conditions and the market perception of our business, may adversely affect the market price of our common stock.

The effect of the Reverse Stock Split on the trading price cannot be predicted with any certainty. The history of similar combinations for companies in similar circumstances is varied, particularly because some investors may view such action by the Company negatively. There is no assurance that:

the market price per share will achieve and maintain the $1.00 average closing price requirement for a sufficient period for our common stock to be approved for continued listing by the NYSE;
the Reverse Stock Split will result in a per share price that will attract brokers and investors who do not trade in lower-priced stocks;
the Reverse Stock Split will enhance the marketability of our common stock to potential investors generally;
the Reverse Stock Split would promote greater liquidity for our stockholders with respect to their shares; or
we would otherwise meet the listing requirements that would allow continued listing of our common stock on the NYSE, including the Minimum Market Capitalization Standard.

In addition, the Reverse Stock Split would have no effect on the number of shares of our authorized capital stock - the total number of authorized shares would remain the same as before the Reverse Stock Split, and only the number of outstanding shares of common stock would decrease. This would have the effect of increasing the number of shares of common stock available for issuance. As of the Record Date, the number of authorized shares of our common stock was 1,000,000,000 shares, which will not be affected by the Reverse Stock Split.

Risk of Dilution

The Board may authorize the issuance of the remaining authorized and unissued shares at the discretion of the Board when opportunities arise, without further stockholder action, except as may be required for a particular transaction by law, the rules of any exchange on which our securities may then be listed, or other agreements or restrictions. There are no preemptive rights relating to the common stock. As such, any issuance of additional shares of common stock would increase the number of outstanding shares of common stock and, unless such issuance was pro rata among existing stockholders, the percentage ownership of existing stockholders would be diluted accordingly. The issuance of additional shares also may cause a decline in the trading price of our common stock.

No Positive Effect on Market Capitalization

15

The market price of our common stock will also be based on the performance of the Company and other factors, some of which are unrelated to the number of shares outstanding. If the Reverse Stock Split is implemented and the market price of our common stock declines, the percentage decline as an absolute number and as a percentage of the overall market capitalization of the Company may be greater than would occur in the absence of the Reverse Stock Split. If the market price of our common stock increases by an amount equal or lesser to the proportion of the Reverse Stock Split, then our market value of listed securities and market value of publicly-held shares will not increase and the Reverse Stock Split will not have any positive effect on our ability to regain compliance with the Minimum Market Capitalization Standard.

In such case, we expect that we would need to raise additional equity capital in order to regain compliance with such requirements, and we cannot assure you that we will be able to do so. We may explore various sources of financing, including through potential future sales of common stock, debt securities or other securities. There can be no assurance, however, even if the Reverse Stock Split is approved and implemented, that any financing transaction would be undertaken or completed. If we are unable to successfully raise sufficient additional capital, whether through future sales of common stock, debt securities or other securities or through strategic and collaborative arrangements, we will not have sufficient cash to fund our planned business operations and or may not be able to continue as a going concern.

Other Considerations

In evaluating the Reverse Stock Split, in addition to the considerations described above, the Board also took into account various other factors associated with reverse stock splits generally. These factors include:

the negative perception of reverse stock splits held by some investors, analysts, and other stock market participants;
the potential anti-takeover effect of the increased proportion of unissued shares to issued shares; and
the adverse effect on liquidity that might be caused by a reduced number of shares outstanding.

While the interest of some investors in our common stock may increase if the Reverse Stock Split results in an increased trading price, certain investors, analysts and other stock market participants view reverse stock splits in a negative light, and implementation of the Reverse Stock Split by the Company may have the effect of limiting interest and investment in the Company by such individuals and entities, and may negatively impact the trading price of our common stock as a result.

As noted above, the Reverse Stock Split also would result in an increased proportion of unissued authorized shares to issued shares, which could have possible anti-takeover effects and could be used by the Company to oppose a hostile takeover attempt, or to delay or prevent changes in our control or management (for example, by permitting issuances that would dilute the stock ownership of a person seeking to effect a change in the composition of the Board or contemplating a tender offer or other transaction for the combination of us with another company).

These authorized but unissued shares could, within the limits imposed by applicable law, be issued in one or more transactions that could make a change of control of the Company more difficult, and therefore more unlikely, or used to resist or frustrate a third-party transaction that is favored by a majority of the independent stockholders. For example, without further stockholder approval, the Board could (within the limits imposed by applicable law) strategically sell shares of common stock in a private transaction to purchasers who would oppose a takeover or favor our then-current Board, or the shares could be available for potential issuance pursuant to a shareholder rights plan. The additional authorized shares could be used to discourage persons from attempting to gain control of us by diluting the voting power of shares then outstanding, or increasing the voting power of persons that would support the Board in a potential takeover situation, including by preventing or delaying a proposed business combination that is opposed by our Board although perceived as desirable by some stockholders. The issuance of additional shares to certain persons allied with our management could have the effect of making it more difficult to remove our current management by diluting the stock ownership or voting rights of persons seeking to cause such removal.

Despite these possible anti-takeover effects, the Reverse Stock Split has been prompted by business and financial considerations and not by the threat of any hostile takeover attempt or any effort of which we are aware to accumulate our stock or to obtain control of the Company by means of a merger, tender offer, solicitation in opposition to management or otherwise (nor is our Board currently aware of any such attempts directed at us). Nevertheless, stockholders should be aware that approval of this Proposal 2 could facilitate future efforts by us to deter or prevent changes in our control, including transactions in which the stockholders might otherwise receive a premium for their shares over then-current market prices.

Finally, the Board considered that the liquidity of our common stock may be negatively impacted by the Reverse Stock Split, given the reduced number of shares that would be outstanding after the Reverse Stock Split, particularly if the per share

16

trading price does not increase as a result of the Reverse Stock Split. In addition, if the Reverse Stock Split is implemented, it will increase the number of our stockholders who own "odd lots" of fewer than 100 shares of common stock, discussed below. Brokerage commission and other costs of transactions in odd lots are generally higher than the costs of transactions of more than 100 shares of common stock. Accordingly, the Reverse Stock Split may not achieve the desired results of increasing marketability of our common stock as described above.

Timing and Selection of Ratio

In order to provide flexibility, the Board is seeking stockholder approval for a range of reverse split ratios of not less than 1-for-10 and not more than 1-for-25. The need for the range is due to the volatility of our stock price, which ranged from a high of $7.25 per share to a low of $0.5690 per share between August 2, 2023 (the first day of trading of ALUR on the NYSE) and October 25, 2025.

The Board believes that enabling the Board to set the exact reverse split ratio within the stated range will provide it with the flexibility to implement the Reverse Stock Split in a manner designed to maximize the anticipated benefits for stockholders. In determining whether to implement the Reverse Stock Split and selecting the exchange ratio, the Board will consider factors such as:

the historical trading price and trading volume of our common stock;
the then-prevailing trading price and trading volume for our common stock;
the anticipated impact of the Reverse Stock Split on the trading price of and market for our common stock;
the total number of shares of common stock outstanding;
potential financing opportunities; and
prevailing general market and economic conditions.

The Board will have sole discretion as to any implementation of, and the exact timing and actual ratio of, the Reverse Stock Split within the range of ratios specified in this Proposal 2 and within one year after the date of the Annual Meeting. The Board may also determine that the Reverse Stock Split is no longer in the best interests of our Company and our stockholders and decide to abandon the Reverse Stock Split at any time before, during or after the Annual Meeting and prior to its effectiveness, without further action by the stockholders.

Impact on Stock Generally

After the effective date of the Reverse Stock Split, if implemented by the Board, the number of shares of common stock issued and outstanding will be reduced due to the Reverse Stock Split, depending upon the ratio determined by the Board, and each stockholder will own a reduced number of shares of common stock. The principal effect of the Reverse Stock Split will be to proportionately decrease the number of outstanding shares of our common stock based on the reverse stock split ratio selected by our Board.

The Reverse Stock Split will affect all holders of our common stock uniformly and will not affect any stockholder's percentage ownership interest in the Company, except as described in "Fractional Shares". In addition, the Reverse Stock Split will not affect any stockholder's proportionate voting power (subject to the treatment of fractional shares).

The number of stockholders of record also will not be affected by the Reverse Stock Split; however, if approved and implemented, the Reverse Stock Split may result in some stockholders owning "odd lots" of less than 100 shares of our common stock. Odd lot shares may be more difficult to sell, and brokerage commissions and other costs of transactions in odd lots are generally somewhat higher than the costs of transactions in "round lots" of even multiples of 100 shares. Our Board believes, however, that these potential effects are outweighed by the benefits of the Reverse Stock Split.

Impact on Common Stock

The Reverse Stock Split will not change the terms of the common stock. After the Reverse Stock Split, the shares of common stock will have the same voting rights and rights to dividends and distributions as, and will be identical in all other respects to, the common stock now authorized. The common stock will remain fully paid and non-assessable.

The table below illustrates certain, but not all, possible Reverse Stock Split ratios within the proposed range, together with the implied number of issued and outstanding shares of the common stock resulting from implementation of the Reverse Stock Split based on __________ shares of common stock issued and outstanding as of the Record Date.

Impact on Options, Option Plans and Warrants

Generally

Based upon the Reverse Stock Split ratio, proportionate adjustments are generally required to be made to the per share exercise price and the number of shares issuable upon the exercise of all outstanding options and warrants entitling the holders to purchase shares of common stock, and upon the conversion of convertible notes and convertible preferred stock. This would result in approximately the same aggregate price being required to be paid under such options or warrants upon exercise, and approximately the same value of shares of common stock being delivered upon such exercise immediately following the Reverse Stock Split as was the case immediately preceding the Reverse Stock Split. The number of shares reserved for issuance pursuant to these securities will be reduced proportionately based upon the reverse stock split ratio.

As of the Record Date, we had:

__________ shares of common stock issued and outstanding,
__________ shares of common stock reserved for issuance upon the exercise of outstanding options,
__________ shares of common stock reserved for issuance upon the vesting of restricted stock unit awards,
__________ shares of common stock reserved for issuance upon the exercise of outstanding warrants,
__________ shares of common stock reserved for issuance upon conversion of the Notes (as defined below),
__________ shares of common stock reserved for issuance upon conversion of the Series A Preferred Stock (as defined below),
__________ shares of common stock reserved for future issuances under the 2023 Stock Option and Incentive Plan (the "2023 Plan"), and
__________ shares of common sock reserved for future issuances under the 2023 Employee Stock Purchase Plan (the "2023 ESPP").

Options and Option Plans

Under our 2010 Stock Incentive Plan, Amended and Restated 2020 Stock Option and Grant Plan, 2023 Plan and 2023 ESPP (collectively, our "Stock Plans"), the Compensation Committee of the Board has the power to determine the appropriate adjustment to the awards granted and shares reserved for issuance under our Stock Plans in the event of a reverse stock split. Accordingly, if the Reverse Stock Split is approved and effected, we expect that the Compensation Committee will proportionately adjust the number of shares available for issuance under the Stock Plans, as well as the number of shares subject to any outstanding award under the Stock Plans, and the exercise, grant price or purchase price relating to any such award or right under the Stock Plans to reflect the Reverse Stock Split. The Compensation Committee will also determine the treatment of fractional shares subject to stock options and other outstanding awards under the Stock Plans. In addition, pursuant to the authority provided under the Stock Plans, the Compensation Committee is expected to authorize the Company to effect any other changes necessary, desirable or appropriate to give effect to the Reverse Stock Split, including any applicable technical, conforming changes to our Stock Plans.

Specifically, it is expected that the number of shares subject to awards under the Stock Plans will be adjusted in each case to equal the product of the number of shares subject to the applicable award immediately prior to the Reverse Stock Split multiplied by the reverse stock split ratio (rounded down to the nearest whole share), that the exercise price of any stock option will be adjusted to equal the quotient of the number of shares subject to the applicable stock option immediately prior to the Reverse Stock Split divided by the reverse stock split ratio (rounded up to the nearest whole cent), and that the stock price goal of any performance-based restricted stock units will be adjusted in each case to equal the product of the applicable price goal in effect immediately prior to the Reverse Stock Split multiplied by the reverse stock split ratio (rounded up to the nearest whole cent).

Warrants

18

If the Reverse Stock Split is approved and effected, our outstanding warrants to purchase shares of our common stock will be proportionately adjusted to reflect the Reverse Stock Split, including the number of shares purchasable upon exercise of such warrants and their exercise prices. Any warrants, including warrants issued or assumed in the Business Combination, warrants issued in the Public Offering (as defined below) and the Private Placement Warrants, including the number of shares purchasable upon exercise of such warrants and their exercise prices, will likewise be proportionately adjusted to reflect the Reverse Stock Split.

No Impact on Rights of Preferred Stock

Our Charter currently authorizes the issuance of 100,000,000 shares of preferred stock, $0.0001 par value per share, of which 2,260,159 shares of Series A Preferred Stock are currently issued and outstanding. The Reverse Stock Split would not increase the authorized number of shares of our preferred stock, and the number of issued and outstanding shares of Series A Preferred Stock will not change; however, proportionate adjustments will be made to the applicable conversion rates and conversion prices of the Series A Preferred Stock. The Reverse Stock Split also will not change the terms of the Series A Preferred Stock. After the Reverse Stock Split, the shares of Series A Preferred Stock will continue to have no voting rights (except as required by law) and will have the same rights to dividends and distributions and will be identical in all other respects to the Series A Preferred Stock now authorized.

No Effect on Par Value

The proposed Reverse Stock Split will not affect the par value of our common stock, which will remain at $0.0001.

Procedures for Implementing the Reverse Stock Split

The effective time of the Reverse Stock Split, if the Reverse Stock Split is approved by stockholders and implemented by the Company, will be the date and time set forth in the Certificate of Amendment that is filed with the Delaware Secretary of State (such time, the "Effective Time"). If the Reverse Stock Split is approved and the Board determines to proceed with the Reverse Stock Split, the exact timing of the filing of the Certificate of Amendment will be determined by our Board.

If, at any time prior to the filing of the Certificate of Amendment with the Delaware Secretary of State, notwithstanding stockholder approval, and without further action by the stockholders, the Board, in its sole discretion, determines that it is in the best interests of the Company and the Company's stockholders to delay the filing of the Certificate of Amendment or abandon the Reverse Stock Split, the Reverse Stock Split may be delayed or abandoned. The Board reserves the right to abandon the Reverse Stock Split without further action by our stockholders at any time before the effectiveness of the filing of the Certificate of Amendment with the Secretary of the State of Delaware, even if the authority to effect the Reverse Stock Split has been approved by our stockholders. By voting in favor of this Proposal 2, you are expressly also authorizing the Board to delay, not to proceed with, and abandon, the Reverse Stock Split if the Board should so decide, in its sole discretion, that such action is in the best interests of the Company and its stockholders.

Beneficial Holders of Common Stock

Upon the implementation of the Reverse Stock Split, the Company intends to treat shares held by stockholders through a bank, broker or other nominee in the same manner as registered stockholders whose shares are registered in their names. Banks, brokers or other nominees will be instructed to effect the Reverse Stock Split for their beneficial holders holding our common stock in street name. However, these banks, brokers or other nominees may have different procedures than registered stockholders for processing the Reverse Stock Split. Stockholders who hold shares of our common stock with a bank, broker or other nominee and who have any questions in this regard are encouraged to contact their banks, brokers or other nominees.

Registered "Book-Entry" Holders of Common Stock

All of the Company's registered holders of common stock hold their shares electronically in book-entry form with the Company's transfer agent, Continental Stock Transfer & Trust Company ("CST"). These stockholders do not have stock certificates evidencing their ownership of the common stock. They are, however, provided with statements from CST reflecting the number of shares registered in their accounts.

Stockholders who hold shares electronically in book-entry form with CST will not need to take action to receive evidence of their shares of post-Reverse Stock Split common stock.

Fractional Shares

19

The Company will not issue fractional shares in connection with the Reverse Stock Split. Instead, stockholders who otherwise would be entitled to receive fractional shares because they hold a number of shares not evenly divisible by the reverse stock split ratio will automatically be entitled to receive an additional fraction of a share of common stock to round up to the next whole share.

Other Effects of the Reverse Stock Split

After the Effective Time, we will continue to be subject to the periodic reporting and other requirements of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Subject to our compliance with applicable continued listing requirements, our common stock will continue to be listed on the NYSE and traded under the symbol "ALUR," although the exchange will add the letter "D" to the end of the trading symbol for a period of 20 trading days after the Effective Time to indicate that a Reverse Stock Split has occurred.

If a Reverse Stock Split is effected, then after the Effective Time, our common stock will have a new Committee on Uniform Securities Identification Procedures ("CUSIP") number, which is a number used to identify our equity securities, and stock certificates for our common stock with the older CUSIP number will need to be exchanged for stock certificates with the new CUSIP number by following the procedures described above under "-Procedure for Implementing the Reverse Stock Split." The Reverse Stock Split is not intended as, and will not have the effect of, a "going private transaction" as described by Rule 13e-3 under the Exchange Act.

Accounting Matters

The proposed amendment to our Charter will not affect the par value of our common stock as noted above. As a result, at the Effective Time, the stated capital on our balance sheet attributable to the common stock will be reduced in the same proportion as the reverse stock split ratio, and the additional paid-in capital account will be credited with the amount by which the stated capital is reduced. The per share net income or loss and net book value of the common stock will be reclassified for prior periods to conform to the post-Reverse Stock Split presentation.

Certain U.S. Federal Income Tax Consequences of the Reverse Stock Split

The following discussion summarizes certain U.S. federal income tax consequences of the Reverse Stock Split to holders of our common stock. This summary addresses the tax consequences only to U.S. Holders. For purposes of this discussion, a "U.S. Holder" is a beneficial owner of our common stock that, for U.S. federal income tax purposes, is or is treated as:

an individual who is a citizen or resident of the United States;
a corporation (or other entity taxable as a corporation for U.S. Federal income tax purposes) created or organized under the laws of the United States, any state thereof, or the District of Columbia;
an estate, the income of which is subject to U.S. federal income tax regardless of its source; or
a trust if either a court within the United States is able to exercise primary supervision over the administration of such trust and one or more United States persons (within the meaning of Section 7701(a)(30) of the Internal Code of 1986, as amended (the "Code")) have the authority to control all substantial decisions of such trust, or the trust has a valid election in effect under applicable Treasury Regulations to be treated as a United States person for U.S. federal income tax purposes.

This summary is based upon current provisions of the Code, existing Treasury Regulations and current administrative rulings and court decisions, all of which are subject to change or different interpretation. Any change, which may or may not be retroactive, could alter the tax consequences to us or our stockholders as described in this summary. No ruling from the Internal Revenue Service ("IRS") has been or will be requested in connection with the Reverse Stock Split and there can be no assurance that the IRS will not challenge the statements and conclusions set forth below or a court would not sustain any such challenge.

No attempt has been made to comment on all U.S. federal income tax consequences of the Reverse Stock Split that may be relevant to particular U.S. Holders, including holders that: (i) are subject to special tax rules such as dealers, brokers and traders in securities, mutual funds, regulated investment companies, real estate investment trusts, insurance companies, banks or other financial institutions or tax-exempt entities; (ii) acquired their shares in connection with stock options, stock purchase plans or other compensatory transactions; (iii) hold their shares as a hedge or as part of a hedging, straddle, "conversion transaction", "synthetic security", integrated investment or any risk reduction strategy; (iv) are partnerships, limited liability companies that are not treated as corporations for U.S. federal income tax purposes, S corporations, or other pass-through entities or investors in such pass-through entities; (v) do not hold their shares as capital assets for U.S. federal income tax purposes (generally, property held

20

for investment within the meaning of Section 1221 of the Code); (vi) hold their shares through individual retirement or other tax-deferred accounts; or (vii) who have a functional currency for U.S. federal income tax purposes other than the U.S. dollar.

In addition, the following discussion does not address state, local or foreign tax consequences of the Reverse Stock Split, the Medicare tax on net investment income, U.S. federal estate and gift tax, the alternative minimum tax, the rules regarding qualified small business stock within the meaning of Section 1202 of the Code, or any other aspect of any U.S. federal tax other than the income tax. The discussion generally assumes that for U.S. federal income tax purposes, the Reverse Stock Split will not be integrated or otherwise treated as part of a unified transaction with any other transaction.

General Tax Treatment of the Reverse Stock Split

The Reverse Stock Split is intended to qualify as a "reorganization" under Section 368(a) of the Code that should constitute a "recapitalization" for U.S. federal income tax purposes. Assuming the Reverse Stock Split qualifies as a reorganization, a U.S. Holder generally will not recognize gain or loss upon the exchange of our common stock for a lesser number of shares of common stock, based upon the reverse stock split ratio. A U.S. Holder's aggregate tax basis in the lesser number of shares of common stock received in the Reverse Stock Split will be the same such U.S. Holder's aggregate tax basis in the shares of our common stock that such U.S. Holder owned prior to the Reverse Stock Split. The holding period for the common stock received in the Reverse Stock Split will include the period during which a U.S. Holder held the shares of our common stock that were surrendered in the Reverse Stock Split. Treasury Regulations provide detailed rules for allocating the tax basis and holding period of the shares of our common stock surrendered to the shares of our common stock received pursuant to the Reverse Stock Split. U.S. Holders of shares of our common stock acquired on different dates and at different prices should consult their tax advisors regarding the allocation of the tax basis and holding period of such shares.

THE FOREGOING IS A SUMMARY OF CERTAIN MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE REVERSE STOCK SPLIT, AND DOES NOT CONSTITUTE A TAX OPINION. EACH HOLDER OF OUR COMMON STOCK SHOULD CONSULT SUCH HOLDER'S TAX ADVISOR REGARDING THE TAX CONSEQUENCES OF THE REVERSE STOCK SPLIT.

Amendment Effective Date

If the proposed amendment to the Charter as described in this Proposal 2 is approved by the stockholders, upon the Board's determination, if any, to effectuate the Reverse Stock Split and of the ratio (within the range approved pursuant to this Proposal 2) of such Reverse Stock Split, the Company will file the Certificate of Amendment reflecting the adopted amendment to our Charter with the Secretary of State of the State of Delaware. The Certificate of Amendment will be effective upon its filing or at such later time as specified in the Certificate of Amendment. If the stockholders do not approve this Proposal 2, the Certificate of Amendment will not be filed with the Secretary of State of the State of Delaware.

Dissenters' Rights

No dissenters' rights are available under the General Corporation Law of the State of Delaware or under our Charter or Bylaws to any stockholder who dissents from this Proposal 2.

Interests of Directors and Executive Officers

Our directors and executive officers do not have any substantial interest, directly or indirectly, in the matters set forth in this Proposal 2 except to the extent of their ownership of shares of common stock or any other of our securities.

Vote Required

The affirmative vote of the holders of a majority of the outstanding shares entitled to vote thereon will be required to approve this Proposal 2. Abstentions and broker non-votes will have the same effect as a vote "AGAINST" this Proposal 2.

The Board of Directors unanimously recommends a vote FOR PROPOSAL 2.

21

PROPOSAL 3: NOTE SHARES ISSUANCE PROPOSAL

Overview

Our Board is asking stockholders to consider and vote upon a proposal to approve the issuance of shares our common stock upon conversion of the Notes pursuant to the Note Purchase Agreement in accordance with NYSE Listing Rule 312.03(b)(i).

The Note Purchase Agreement

On April 14, 2024, the Company entered into the Note Purchase Agreement with RTW as Principal Purchaser, the Purchasers party thereto, and Acquiom Agency Services LLC as collateral agent for the Purchasers and Principal Purchaser. Pursuant to the Note Purchase Agreement, the Company issued and sold $48 million aggregate principal amount of convertible senior secured notes (the "Notes") to the Purchasers in a private placement transaction. The Company used the proceeds from the issuance of the Notes to refinance its then-outstanding obligations under the Credit Agreement and Guaranty, dated as of August 1, 2023 (as subsequently amended) with Fortress Credit Corp. as administrative agent for the lenders from time to time party thereto. The Company repaid all obligations under the Credit Agreement and Guaranty with Fortress in full with the proceeds of the Notes, as well as fees and expenses in connection therewith and in connection with the transactions contemplated by the Note Purchase Agreement.

NYSE Listing Rule 312.03(b)(i)

NYSE Listing Rule 312.03(b)(i) ("Listing Rule 312.03(b)(i)") provides that stockholder approval is required prior to the issuance of common stock, or of securities convertible into or exercisable for common stock, in any transaction or series of related transactions to a director, officer, controlling shareholder or member of a control group, or any other substantial security holder of the issuer that has an affiliated person who is an officer or director of the company (each, an "Active Related Party") if the number of shares of common stock to be issued, or if the number of shares of common stock into which the securities may be convertible or exercisable, exceeds either one percent (1.0%) of the number of shares of common stock or one percent (1.0%) of the voting power outstanding before the issuance. However, stockholder approval is not required if such transaction is a cash sale for a price that is at least the "Minimum Price."

"Minimum Price" is defined in Listing Rule 312 as a price that is the lower of (i) the Official Closing Price immediately preceding the signing of the binding agreement, or (ii) the average Official Closing Price for the five trading days immediately preceding the signing of the binding agreement. "Official Closing Price" means the closing price on the NYSE as reported to the Consolidated Tape immediately preceding the signing of a binding agreement to issue the securities.

Note Conversion

The Notes are convertible into shares of our common stock at a Purchaser's election at any time after the earliest of (i) the date on which stockholder approval is obtained pursuant to Listing Rule 312.03(b)(i) as discussed below, (ii) December 31, 2025, (iii) the date of a Fundamental Change Company Notice (as defined in the Note Purchase Agreement), and (iv) the Make-Whole Fundamental Change Effective Date (as defined in the Note Purchase Agreement), subject to certain terms and limitations in the Note Purchase Agreement, based on a conversion rate of 617.2840 shares of common stock per $1,000 principal amount of Notes (equivalent to a conversion price of approximately $1.62 per share, which represents a 35% conversion premium to the lowest price per share in an equity financing for capital raising purposes ending on the date on which the Company has raised aggregate gross offering proceeds of at least $15,000,000 (the "Next Equity Financing")), subject to adjustment as set forth in the Note Purchase Agreement.

Consummation of the Public Offering and Private Placement (each as defined in Proposal 4 below) on July 1, 2024, in which the Company raised in excess of $15 million aggregate gross proceeds, constituted the "Next Equity Financing" under the Note Purchase Agreement.

Stockholder Approval Requirement

The NYSE determined that RTW is an Active Related Party under Listing Rule 312.03(b)(i). Because the conversion price of the Notes was subject to a reset provision in connection with the Next Equity Financing that resulted in the conversion price falling to a price below the NYSE Minimum Price, pursuant to the terms of the Note Purchase Agreement, we may not deliver shares of common stock upon conversion of the Notes in excess of 1% of the number of shares of our common stock outstanding as of April 14, 2024 unless we obtain stockholder approval of such issuance. The Company is required to include a proposal in our definitive proxy statement on Schedule 14A seeking stockholder approval no later than December 31, 2025. If the Company does not obtain stockholder approval by such date, it must call a special meeting of stockholders each 90-day period thereafter at least two times, and thereafter at each subsequent annual meeting until stockholder approval is obtained or the Notes are no longer outstanding.

22

Any shares of common stock issued upon conversion of the Notes prior to obtaining stockholder approval are not entitled to vote in favor of this Proposal 3. As of October 25, 2024, no Notes or any portion thereof had been converted, and the Company had not issued any shares of common stock upon conversion of any Notes.

Rights and Limitations

Registration Rights

Pursuant to the Note Purchase Agreement, the Company agreed to prepare, and, as soon as practicable but in no event later than 45 days after the closing of the transactions contemplated by the Note Purchase Agreement, file with the SEC a registration statement under the Securities Act on appropriate form covering the resale of the full amount of the shares issuable upon conversion of the Notes.

The Company filed a registration statement on Form S-1 (as amended, the "Resale Registration Statement") registering for resale by RTW up to an aggregate of 65,211,325 shares of common stock, including: (i) 60,691,007 shares of common stock issuable upon the conversion of the Notes, exclusive of any accrued but unpaid interest on the Notes that may be added to the outstanding principal amount of such Notes at the time of conversion, (ii) 2,260,159 shares of common stock issuable upon conversion of the Series A Preferred Stock, and (iii) 2,260,159 shares of common stock issuable upon the exercise of the Private Placement Warrants. The Resale Registration Statement was declared effective on October 7, 2024 and remains in effect.

Conversion Shares

The actual number of shares of our common stock that may be issued upon conversion of the Notes will vary depending on the conversion price of the Notes at the time of conversion, not to exceed 479,196 shares of common stock, or 1% of the number of shares of the common stock outstanding as of April 14, 2024, unless we obtain stockholder approval in accordance with Listing Rule 312.03(b)(i). The Company registered on the Resale Registration Statement the number of shares of common stock issuable assuming the shares are issued at the current conversion rate of 617.2840 shares of common stock per $1,000 principal amount of Notes, subject to stockholder approval for such issuance and exclusive of any accrued but unpaid interest on the Notes that may be added to the outstanding principal amount of such Notes at the time of conversion.

If certain corporate events that constitute a Make-Whole Fundamental Change occur, then the conversion rate will, in certain circumstances, be increased for a specified period of time up to a maximum rate of an additional 647.1120 shares of common stock per $1,000 principal amount of Notes. In addition, calling any Note for redemption will also constitute a "Make-Whole Fundamental Change" with respect to that Note, in which case the conversion rate applicable to the conversion of that Note will be increased in certain circumstances if it is converted after it is called for redemption. In addition, the number of shares of common stock issuable upon conversion of the Notes may increase as interest on the Notes accrues.

Beneficial Ownership Limitations

Pursuant to the terms of the Note Purchase Agreement, each Purchaser is subject to a beneficial ownership conversion limitation such that no Purchaser is permitted to convert Notes to the extent it would result in such Purchaser and its affiliates beneficially owning more than the beneficial ownership limitation, currently set at 9.99% of the outstanding shares of our common stock.

Governance Rights

Pursuant to the terms of the Note Purchase Agreement, until the Notes are converted or repaid in full, RTW is entitled to designate one representative to serve as a non-voting board observer to the Company's Board. In August 2024 we expanded our Board from seven to eight members and in September 2024, we appointed Keith Johns to our Board, which was approved by RTW in satisfaction of certain obligations to RTW set forth in the Note Purchase Agreement with respect to designation of directors to our Board.

Reason for Seeking Stockholder Approval

As discussed above, Listing Rule 312.03(b)(i) requires us to obtain stockholder approval prior to the issuance of common stock, or of securities convertible into or exercisable for common stock, to an Active Related Party of the Company if the number of shares of common stock to be issued, or the number of shares of common stock into which the securities may be convertible or exercisable, exceeds 1% of the number of shares of common stock outstanding before the issuance and the transaction is not a cash sale for a price that is at least the NYSE Minimum Price. As a result of the conversion price of the Notes falling below the NYSE Minimum Price in connection with the Next Equity Financing, we must obtain approval for the issuances to RTW, an Active Related Party as determined by the NYSE.

23

Stockholder approval of this Proposal 3 will constitute stockholder approval for purposes of Listing Rule 312.03(b)(i) and will satisfy the Company's requirements to obtain stockholder approval under the Note Purchase Agreement.

Consequences for Failing to Obtain Stockholder Approval

In the event that this Proposal 3 is not approved by our stockholders, we will include a proposal in our definitive proxy statement on Schedule 14A seeking stockholder approval of the Note Shares Issuance in connection with our 2025 annual meeting of stockholders.

If the Company does not obtain stockholder approval of the Note Shares Issuance at our 2025 annual meeting of stockholders or otherwise prior to December 31, 2025, we must call a special meeting of stockholders each 90-day period thereafter at least two times, and thereafter at each subsequent annual meeting until stockholder approval of the Note Shares Issuance is obtained, or the Notes are no longer outstanding. Such requirement to include such proposal potentially multiple times after the 2024 Annual Meeting imposes on the Company significant costs, including legal and accounting costs, and diversion of management attention.

If we are prohibited from issuing shares of our common stock upon conversion of the Notes because stockholder approval of the Note Shares Issuance has not been obtained, then the Company must pay cash in lieu of issuing such shares upon conversion (to "Cash Settle"), at a price per share equal to the average of daily volume-weighted average prices ("VWAPs") of the common stock for the five trading days ending on the trading day immediately preceding the conversion date for such conversion.

We can give no assurances that sufficient funds will be available to Cash Settle the Notes. Any such use of cash, if available, will reduce the funds available to the Company to operate its business, and we may have to significantly delay, scale back or discontinue the further development and commercialization efforts of one or more of our products, or may be forced to reduce or terminate our operations.

Interests of Certain Persons

When you consider the Board's recommendation to vote in favor of this Proposal 3, you should be aware that our directors and executive officers and existing stockholders may have interests that may be different from, or in addition to, the interests of other of our stockholders. In particular, RTW is a party to the transactions and has the nomination and approval rights described above and, as a result, has an interest in the approval of this Proposal 3.

Potential Adverse Effects

Dilution

If our stockholders vote to approve the Note Shares Issuance, the issuance of shares of our common stock upon conversion of the Notes will not require any additional approval by our common stockholders. The issuance of such common stock will have a dilutive effect on current stockholders other than the Purchasers, in that the percentage ownership of the Company held by such other current stockholders will decline as a result of the issuance of such common stock. The issuance of such common stock will also have a dilutive effect on book value per share and any future earnings per share. Dilution of equity interests could also cause prevailing market prices for our common stock to decline. The dilutive impact of the Note Shares Issuance cannot be determined as the date hereof because the number of shares into which such securities may be converted or exercised will not be known until the applicable conversion date of the Notes.

Potential Negative Effect on Market Price

The shares of our common stock issued upon conversion of the Notes registered on the Resale Registration Statement (as the same may be amended in the future) will be freely tradable without restriction or further registration. As a result, a substantial number of shares of our common stock may be sold by RTW in the public market. If there are significantly more shares of our common stock offered for sale than buyers are willing to purchase, then the market price of our common stock will decline to a market price at which buyers are willing to purchase the offered common stock and sellers remain willing to sell our common stock. The sale of the shares by RTW, or the perception that such sales may occur, could increase the volatility of the market price of our common stock or result in a significant decline in the public trading price of our common stock. We cannot predict the effect, if any, that market sales of those shares of common stock or the availability of those shares for sale will have on the market price of our common stock.

Required Vote and Recommendation of the Board for Proposal 3

24

The affirmative vote of the holders of a majority of the votes properly cast will be required to approve this Proposal 3. Abstentions and broker non-votes are not considered to be votes cast and, accordingly, will have no effect on the outcome of the vote on this Proposal 3.

The Board of Directors unanimously recommends a vote FOR

the NOTE SHARES ISSUANCE PROPOSAL.

PROPOSAL 4: PRIVATE PLACEMENT SHARES ISSUANCE PROPOSAL

Overview

Our Board is asking stockholders to consider and vote upon a proposal to approve the issuance of shares of our common stock upon conversion of the Company's Series A Preferred Stock (as defined below), and upon exercise of the Private Placement Warrants (as defined below), in accordance with NYSE Listing Rule 312.03(b)(i).

The Series A Preferred Stock

The Company entered into a Subscription Agreement, dated as of June 28, 2024 (the "Subscription Agreement"), with funds affiliated with RTW, pursuant to which it sold 2,260,159 shares of a newly created series of preferred stock, the Series A non-voting convertible preferred stock, par value $0.0001 per share (the "Series A Preferred Stock"), and 2,260,159 private placement warrants ("Private Placement Warrants") to purchase common stock, for an aggregate purchase price of approximately $2.7 million (the "Private Placement"). The purchase price per share of the Series A Preferred Stock and accompanying Private Placement Warrant was $1.20, which price was equal to the per share offering price for shares of common stock and public warrants sold by the Company in a concurrent public equity offering (the "Public Offering"). RTW also participated in the Public Offering; RTW's aggregate investment in the Public Offering and Private Placement was $3 million. The Private Placement and Public Offering closed on July 1, 2024.

NYSE Listing Rule 312.03(b)(i)

Listing Rule 312.03(b)(i) provides that stockholder approval is required prior to the issuance of common stock, or of securities convertible into or exercisable for common stock, in any transaction or series of related transactions to an Active Related Party if the number of shares of common stock to be issued, or if the number of shares of common stock into which the securities may be convertible or exercisable, exceeds either one percent (1.0%) of the number of shares of common stock or one percent (1.0%) of the voting power outstanding before the issuance. However, stockholder approval is not required if such transaction is a cash sale for a price that is at least the "Minimum Price."

Series A Preferred Stock Conversion

The Series A Preferred Stock automatically converts into shares of common stock following stockholder approval in accordance with Listing Rule 312.03(b)(i). Each share converts into (i) a number of shares of common stock on a 1:1 conversion ratio (subject to adjustment, the "Conversion Ratio"), subject to the beneficial ownership limitation discussed below, and (ii) pre-funded conversion warrants exercisable for a number of shares of common stock equal to the Conversion Ratio that would have been issued pursuant to clause (i) but for the beneficial ownership limitation.

Stockholder Approval Requirement; Voting Restrictions

The NYSE determined that RTW is an Active Related Party under Listing Rule 312.03(b)(i). Because RTW is an Active Related Party, the purchase by RTW of shares of common stock and warrants in the Public Offering was limited to 1% of the outstanding shares of common stock immediately prior to the Public Offering. The remainder of such investment was made in the Private Placement for the shares of Series A Preferred Stock convertible into our common stock and Private Placement Warrants exercisable for the same.

Pursuant to the Subscription Agreement and consistent with the requirement of the Note Purchase Agreement, the Company is required to include a proposal in our definitive proxy statement on Schedule 14A seeking stockholder approval of the issuance of shares of common stock upon conversion of the Series A Preferred Stock and the exercise of the Private Placement Warrants no later than December 31, 2025. If the Company does not obtain stockholder approval by such date, it must call a special meeting of stockholders each 90-day period thereafter at least two times, and thereafter at each subsequent annual meeting until stockholder approval is obtained or the shares of Series A Preferred Stock and Private Placement Warrants are no longer outstanding.

Any shares of common stock purchased by RTW in the Public Offering are not entitled to vote in favor of this Proposal 4.

Rights and Limitations

Registration Rights

The Company filed the Resale Registration Statement registering for resale by RTW up to an aggregate of 65,211,325 shares of common stock, including: (i) 60,691,007 shares of common stock issuable upon the conversion of the Notes, exclusive of any accrued but unpaid interest on the Notes that may be added to the outstanding principal amount of such Notes at the time

26

of conversion, (ii) 2,260,159 shares of common stock issuable upon conversion of the Series A Preferred Stock, and (iii) 2,260,159 shares of common stock issuable upon the exercise of the Private Placement Warrants. The Resale Registration Statement was declared effective on October 7, 2024 and remains in effect.

Conversion Shares

The actual number of shares of our common stock that may be issued upon conversion of the Series A Preferred Stock and upon exercise of the Private Placement Warrants shall not exceed 479,730 shares of common stock, or 1% of the number of shares of the common stock outstanding as of June 28, 2024, unless we obtain stockholder approval in accordance with Listing Rule 312.03(b)(i). Effective as of 5:00 pm (Eastern Time) on the third business day following receipt of stockholder approval of the Private Placement Shares Issuance, each share of Series A Preferred Stock will automatically convert into shares of our common stock at the then-applicable Conversion Ratio and pre-funded conversion warrants.

Beneficial Ownership Limitations

The terms of the Series A Preferred Stock provide that in no event shall the Series A Preferred Stock be converted into a number of shares of common stock exceeding 9.99% of the total number of shares of common stock outstanding. In addition, a holder of Private Placement Warrants may not exercise the Private Placement Warrant if such holder, together with its affiliates, would beneficially own more than 4.99% (or, upon election by a holder prior to the issuance of the Private Placement Warrants, 9.99%) of the number of shares of common stock outstanding immediately after giving effect to such exercise.

Reason for Seeking Stockholder Approval

As discussed above, Listing Rule 312.03(b)(i) requires us to obtain stockholder approval prior to the issuance of common stock, or of securities convertible into or exercisable for common stock, to an Active Related Party of the Company if the number of shares of common stock to be issued, or the number of shares of common stock into which the securities may be convertible or exercisable, exceeds 1% of the number of shares of common stock outstanding before the issuance and the transaction is not a cash sale for a price that is at least the Minimum Price. As a result of the purchase price of the shares of Series A Preferred Stock falling below the NYSE Minimum Price, we must obtain approval for the Private Placement Shares Issuance to RTW, an Active Related Party as determined by the NYSE.

Stockholder approval of this Proposal 4 will constitute stockholder approval for purposes of Listing Rule 312.03(b)(i) and will satisfy the Company's requirements to obtain stockholder approval under the Subscription Agreement.

Consequences for Failing to Obtain Stockholder Approval

In the event that this Proposal 4 is not approved by our stockholders, we will include a proposal in our definitive proxy statement on Schedule 14A seeking stockholder approval of the Private Placement Shares Issuance in connection with our 2025 annual meeting of stockholders.

If the Company does not obtain stockholder approval of the Private Placement Shares Issuance at our 2025 annual meeting of stockholders or otherwise prior to December 31, 2025, we must call a special meeting of stockholders each 90-day period thereafter at least two times, and thereafter at each subsequent annual meeting until stockholder approval of the Private Placement Shares Issuance is obtained, or the shares of Series A Preferred Stock and Private Placement Warrants are no longer outstanding. Such requirement to include such proposal potentially multiple times after the 2024 Annual Meeting imposes on the Company significant costs, including legal and accounting costs, and diversion of management attention.

If we fail to obtain stockholder approval of the Private Placement Shares Issuance, we will further be required to redeem for cash (except to the extent prohibited by Delaware law governing distributions to stockholders) any shares of Series A Preferred Stock that did not automatically convert upon such stockholder approval and remain outstanding on December 31, 2026, at a redemption price equal to the VWAP per share of the common stock on the trading market during the 20 consecutive trading day period ending and including the trading day immediately preceding the redemption date.

If the shares of Series A Preferred Stock are redeemed and not converted due to our failure to obtain stockholder approval of the Private Placement Shares Issuance, we must offer to repurchase the Private Placement Warrants at a price per share of underlying common stock equal to the redemption price minus the exercise price of the Private Placement Warrants.

We can give no assurances that sufficient funds will be available to redeem the shares of Series A Preferred Stock or repurchase the Private Placement Warrants. Any such use of cash, if available, will reduce the funds available to the Company to operate its business, and we may have to significantly delay, scale back or discontinue the further development and commercialization efforts of one or more of our products, or may be forced to reduce or terminate our operations.

27

In addition, the Private Placement Warrants are not exercisable until we obtain stockholder approval of the Private Placement Shares Issuance. Thus, failure to obtain such approval will prevent holders of the Private Placement Warrants from exercising, and the Company will not be able to receive the exercise price for such warrants until it has obtained stockholder approval.

Interests of Certain Persons

When you consider the Board's recommendation to vote in favor of this Proposal 4, you should be aware that our directors and executive officers and existing stockholders may have interests that may be different from, or in addition to, the interests of other of our stockholders. In particular, RTW is a party to the transactions and has the nomination and approval rights described above and, as a result, has an interest in the approval of this Proposal 4.

Potential Adverse Effects

Dilution

If our stockholders vote to approve the Private Placement Shares Issuance, the issuance of shares of our common stock upon conversion of the Series A Preferred Stock and exercise of the Private Placement Warrants will not require any additional approval by our common stockholders. The issuance of such common stock will have a dilutive effect on current stockholders other than the purchasers, in that the percentage ownership of the Company held by such other current stockholders will decline as a result of the issuance of such common stock. The issuance of such common stock will also have a dilutive effect on book value per share and any future earnings per share. Dilution of equity interests could also cause prevailing market prices for our common stock to decline. The dilutive impact of the Private Placement Shares Issuance cannot be determined as the date hereof because the number of shares into which such securities may be converted or exercised will not be known until the applicable conversion date of the Series A Preferred Stock and exercise of the Private Placement Warrants.

Potential Negative Effect on Market Price

The shares of our common stock issued upon conversion of the Series A Preferred Stock and exercise of the Private Placement Warrants registered on the Resale Registration Statement (as the same may be amended in the future) will be freely tradable without restriction or further registration. As a result, a substantial number of shares of our common stock may be sold by RTW in the public market. If there are significantly more shares of our common stock offered for sale than buyers are willing to purchase, then the market price of our common stock will decline to a market price at which buyers are willing to purchase the offered common stock and sellers remain willing to sell our common stock. The sale of the shares by RTW, or the perception that such sales may occur, could increase the volatility of the market price of our common stock or result in a significant decline in the public trading price of our common stock. We cannot predict the effect, if any, that market sales of those shares of common stock or the availability of those shares for sale will have on the market price of our common stock.

Required Vote and Recommendation of the Board for Proposal 4

The affirmative vote of the holders of a majority of the votes properly cast will be required to approve this Proposal 4. Abstentions and broker non-votes are not considered to be votes cast and, accordingly, will have no effect on the outcome of this Proposal 4.

PROPOSAL 5: AUDITOR Ratification PROPOSAL

The Audit Committee of the Board ("Audit Committee") has appointed Deloitte & Touche LLP ("Deloitte") as our independent registered public accounting firm for the fiscal year ending December 31, 2024. Deloitte also served as our independent registered public accounting firm for the fiscal years ended December 31, 2023 and December 31, 2022.

Neither Deloitte nor any of its members has any direct or indirect financial interest in or any connection with us in any capacity other than as our auditors, providing audit and non-audit related services.

A representative of Deloitte is expected to attend the Annual Meeting and to have an opportunity to make a statement and be available to respond to appropriate questions from stockholders.

Audit Committee Pre-Approval Policy and Procedures

Our Audit Committee has adopted procedures requiring the pre-approval of all audit and permissible non-audit services that are to be performed by our independent registered public accounting firm in order to assure that these services do not impair the auditor's independence. In accordance with the pre-approval procedures, the Audit Committee generally approves the performance of specific services subject to a cost limit for all such services. This general approval is reviewed, and if necessary, modified, at least annually. Management must obtain the specific prior approval of the Audit Committee for each engagement of our independent registered public accounting firm to perform any other audit or permissible non-audit services. The Audit Committee may delegate pre-approval authority to one or more of its independent members, but does not delegate its responsibility to approve services performed by our independent registered public accounting firm to any member of management.

All of the services rendered by Deloitte with respect to the 2023 and 2022 fiscal years were pre-approved by the Audit Committee in accordance with this policy.

Ratification

Although ratification of our appointment of Deloitte is not required, we value the opinions of our stockholders and believe that stockholder ratification of our appointment of Deloitte is a good corporate governance practice.

In the event that the appointment of Deloitte is not ratified by the stockholders, the Audit Committee will consider this fact when it appoints the independent registered public accounting firm for the fiscal year ending December 31, 2025. Even if the

29

appointment of Deloitte is ratified, the Audit Committee retains the discretion to appoint a different independent auditor at any time if it determines that such a change is in the interest of the Company.

Vote Required

This Proposal 5 requires the affirmative vote of the holders of a majority of the votes properly cast. Abstentions and broker non-votes are not considered to be votes cast and, accordingly, will have no effect on the outcome of the vote on this Proposal 5.

CORPORATE GOVERNANCE

General

We believe that good corporate governance is important to ensure that our Company is managed for the long-term benefit of our stockholders. We periodically review our corporate governance policies and practices and compare them to those suggested by various authorities in corporate governance and the practices of other public companies. As a result, we have adopted policies and procedures that we believe are in the best interests of our Company and our stockholders. Key information regarding our corporate governance initiatives can be found on our corporate website at investors.allurion.com under "Governance Documents," including our Corporate Governance Guidelines, our Code of Business Conduct and Ethics (our "Code of Conduct"), and the charters for the committees of our Board, described below.

Corporate Governance Guidelines

Our Corporate Governance Guidelines assist our Board in the exercise of its duties and responsibilities and to serve the best interests of our company and our stockholders. These guidelines, which provide a framework for the conduct of Board business, provide that:

at least a majority of the members of the Board shall be independent directors as defined by NYSE rules;
the independent directors shall meet at least quarterly, and at other times at the request of any independent director, in executive session;
directors shall have full and free access to management and, as necessary and appropriate, independent advisors; and
at least annually, the Nominating and Corporate Governance Committee of the Board (the "Nominating and Corporate Governance Committee") oversees a self-evaluation by the Board to assess the effectiveness of the Board and its committees.

Our Board is responsible for managing or supervising the management of our business and affairs. This includes appointing our Chief Executive Officer, advising management on strategic issues, approving our business and other plans, and monitoring our performance against those plans and against our operating and capital budgets. In addition, our Board also receives and considers recommendations from its various committees with respect to matters such as:

the compensation of our executive officers and directors;
criteria for Board and committee membership;
persons to be nominated for election as members of the Board and to each of the committees of the Board; and
matters relating to our corporate governance, including to our Code of Conduct and Corporate Governance Guidelines.

Independence

Our Board has determined that each member of the Board, other than Dr. Gaur, qualifies as independent, as defined under the listing standards of the NYSE. In addition, our Board has determined that each of the members of the Audit Committee, Nominating and Corporate Governance Committee, and Compensation Committee is independent in accordance with the rules of the NYSE and, in, the case of the members of the Audit Committee, the rules of the SEC as noted below under "Committees of the Board."

In determining the independence of its members, the Board considered all the facts and circumstances it deemed relevant in determining their independence, including, but not limited to, the director's commercial, industrial, banking, consulting, legal, accounting, charitable, and familial relationships. We are subject to the rules of the SEC and NYSE relating to the memberships, qualifications, and operations of the Audit Committee.

Director Qualifications

Our Nominating and Corporate Governance Committee is responsible for identifying individuals qualified to serve as directors, consistent with criteria approved by our Board, and recommending to the Board qualified individuals to be nominated for election as directors at each annual meeting of stockholders.

32

In identifying prospective director candidates, the Nominating and Corporate Governance Committee may consider all facts and circumstances that it deems appropriate or advisable, including, among other things, the skills of the prospective candidate, such candidate's depth and breadth of business experience or other background characteristics, such candidate's independence, and the needs of the Board. At a minimum, the Nominating and Corporate Governance Committee must be satisfied that each recommended nominee meets the following minimum qualifications:

(i)
relevant experience and expertise to enable the candidate to be able to offer germane advice and guidance to management;
(ii)
proven achievement and competence in the candidate's field;
(iii)
the ability to exercise sound business judgment;
(iv)
an understanding of the fiduciary responsibilities required of a director;
(v)
commitment to devoting time and energy to our affairs;
(vi)
a diverse personal background, perspective, and experience; and
(vii)
commitment to vigorously represent the long-term interests of our stockholders.

In addition to any other standards the Nominating and Corporate Governance Committee deems appropriate from time to time for the overall structure and composition of the Board, the Nominating and Corporate Governance Committee may consider whether the candidate, if elected, assists in achieving a mix of Board members that represents a diversity of background and experience.

Nomination Policies and Procedures

The Nominating and Corporate Governance Committee will consider for recommendation any candidate properly recommended by a stockholder.

Stockholders who wish to nominate qualified candidates to serve as directors must notify the Company in writing, by notice delivered to the attention of the Secretary of the Company at the address of the Company's executive offices as set forth in the Company's periodic reports as filed with the SEC, of a proposed nominee. In order to ensure meaningful consideration of such candidates, notice must be timely received as set forth under "Stockholder Proposals for 2025" below.

The notice must set forth:

the nominee's name, age, business address and residence address;
the nominee's principal occupation or employment, and a description of the nominee's background and qualifications as provided by the nominee;
the class and number of shares of capital stock of the Company that are held of record or are beneficially owned by the nominee or their affiliates or associates;
any other information relating to such proposed nominee that is required to be disclosed in solicitations of proxies for election of directors in an election contest, or is otherwise required, in each case pursuant to Regulation 14A under the Exchange Act (including without limitation such person's written consent to being named in the proxy statement as a nominee and to serving as a director if elected); and
such other information as required by Section 2 of Article I of our Bylaws.

The notice also must include a description of all arrangements or understandings between or among the nominating stockholder and each nominee and any other person or persons (naming such person or persons) pursuant to which the nominations are to be made by the stockholder or concerning the nominee's potential service on the Board, as well as certain representations by the nominee with respect to matters such as compliance with law and the Company's corporate policies and procedures.

The nominating stockholder must provide such stockholder's name and address, as they appear on the Company's books, the class or series and number of all shares of capital stock of the Company that are, directly or indirectly, owned beneficially or of record by such stockholder or any of their affiliates or associates (as such terms are defined in

33

Rule 12b-2 promulgated under the Exchange Act), a description of all agreements, arrangements or understandings to which the stockholder or any of their affiliates or associates is a party pertaining to the nomination, and identification of the names and addresses of other stockholders (including beneficial owners) known by the nominating stockholder to support such nomination together, to the extent known, with the class and number of all shares of the Company's capital stock owned beneficially or of record by such other stockholders or beneficial owners.

The foregoing description of the stockholder director nomination process does not purport to be complete and is qualified in its entirety by reference to our Bylaws. Submissions received through the Company's stockholder nomination process will be forwarded to the Nominating and Corporate Governance Committee for review. Only those submissions that comply with the procedures summarized herein and more fully set forth in our Bylaws, and those nominees who satisfy the qualifications determined by the Nominating and Corporate Governance Committee for directors of the Company, will be considered and eligible for election.

The Nominating and Corporate Governance Committee may also engage third parties, including executive search firms, to assist it with identifying and evaluating potential director nominees. The Nominating and Corporate Governance Committee engaged True Capital Partners, LLC ("True") to assist it in identifying candidates that satisfied the director qualifications the Nominating and Corporate Governance Committee had established, and assist the committee in screening such candidates. Mr. Hudson, Ms. Alberti-Perez, and Mr. Johns were identified and screened by True. Mr. Hudson was selected pursuant to the nomination right of Remus as provided under the Investor Rights Agreement. Mr. Johns was appointed by the Board and approved by RTW in satisfaction of certain obligations to RTW under the Note Purchase Agreement.

Board and Committee Meetings Attendance

During 2023, following the closing of the Business Combination on August 1, 2023, the Board met five times, the Audit Committee met three times, the Compensation Committee met five times and acted by written consent once, and the Nominating and Corporate Governance Committee met one time.

During 2023, following the closing of the Business Combination, each member of the Board attended in person or participated in 75% or more of the aggregate of (i) the total number of meetings of the Board (held during the period for which such person has been a director) and (ii) the total number of meetings held by all committees of the Board on which such person served (during the periods that such person served).

Director Attendance at Annual Meeting of Stockholders

Directors are encouraged to attend the annual meeting of stockholders.

Stockholder Communication Policy

The Board provides to every securityholder the ability to communicate with the Board, as a whole, and with individual directors on the Board through an established process for securityholder communication (a "Securityholder Communication") as follows:

For a Securityholder Communication directed to the Board as a whole, stockholders may send such communication to the attention of the Chair of the Board via U.S. Mail or Expedited Delivery Service to the Company's principal office address.
For a Securityholder Communication directed to an individual director in such director's capacity as a member of the Board, securityholders may send such communication to the attention of the individual director via U.S. Mail or Expedited Delivery Service to the Company's principal office address.

The Company will forward any such Securityholder Communication to each director by U.S. mail, and the co-Chair of the Board in such person's capacity as a representative of the Board.

Communications from an officer or director of the Company, and proposals submitted by securityholders to be included in the Company's annual proxy statement pursuant to Rule 14a-8 of the Exchange Act (and related communications), will not be viewed as a Securityholder Communication. Communications from an employee or agent of the Company will be viewed as Securityholder Communication only if such communications are made solely in such employee's or agent's capacity as a securityholder.

34

Communications that are clearly of a marketing nature, or unduly hostile, threatening, illegal or similarly inappropriate, will not be forwarded, and the Company has the authority to discard such communications or take appropriate legal action.

Compensation Recovery Policy

In light of the SEC's adoption of final clawback rules in October 2022 and the NYSE's adoption of final listing standards consistent with the SEC rules in June 2023, we adopted a Compensation Recovery Policy effective as of October 2, 2023. If we are required to prepare an accounting restatement due to material non-compliance with any financial reporting requirements under applicable securities laws, the Compensation Recovery Policy requires (subject to certain limited exceptions described in the policy and permitted by the final clawback rules) that we recover erroneously awarded compensation received by any current or former executive officer in the three fiscal years prior to the date we were required to restate our financial statements that is in excess of the amount that would have been received based on the restated financial statements.

Compensation Committee Interlocks and Insider Participation

During 2023, the members of our Compensation Committee included Michael Davin, Nicholas Lewin, and Douglas Hudson. None of the members of our Compensation Committee has ever been an officer or employee of our Company, or had any other relationship requiring disclosure herein. None of our executive officers serve, or have served during the last fiscal year, as a member of the board of directors or compensation committee of any other entity that has or has had one or more executive officers serving as a member of our Board or Compensation Committee.

Policy on Insider Trading, Pledging, and Hedging

Our Insider Trading Policy prohibits our directors (including non-employee directors), officers, employees, consultants, and their "affiliated persons" (as defined in our Insider Trading Policy) from engaging in the following transactions:

trading in our securities, whether for their own account or for the account of another, while in the possession of material, nonpublic information about us;
disclosing material, nonpublic information about us to others who may trade on the basis of that information ("tipping");
selling any of our securities that they do not own at the time of the sale (referred to as a "short sale");
buying or selling puts, calls, other derivative securities of our securities, or any derivative securities that provide the economic equivalent of ownership of any of our securities or an opportunity, direct or indirect, to profit from any change in the value of our securities or engaging in any other hedging transaction with respect to our securities;
using our securities as collateral in a margin account; and
pledging our securities as collateral for a loan (or modifying an existing pledge).

Board Leadership Structure and Board's Role in Risk Oversight

Omar Ishrak and Krishna Gupta are co-chairmen of the Board, and Dr. Ishrak is our lead independent director. Our co-chairmen preside at all meetings of our Board. Currently, the role of the co-chairmen of the Board is separated from the role of Chief Executive Officer. Separating these positions allows our Chief Executive Officer to focus on our day-to-day business, while allowing the co-chairmen to lead the Board in its fundamental role of providing advice to and independent oversight of management.

The Board has not adopted a position description for the co-chairmen. However, there is a shared understanding on the Board of the co-chairmen's responsibilities. The co-chairmen's primary role is to provide leadership to the Board and its committees, including chairing meetings in a manner that facilitates open discussions and expressions of competing views. The co-chairmen are also responsible for, among other things, assisting the Board in obtaining information required for the performance of its duties, retaining appropriately qualified and independent advisors as needed, working with the Board to support Board development and to ensure a proper committee structure is in place, providing a link between the Board and management, and acting in an advisory capacity to the Chief Executive Officer in all matters concerning the interests and management of Allurion.

Our Board recognizes the time, effort, and energy that the Chief Executive Officer must devote to this position and the commitment required to serve as a chairman of the Board. Our Board also believes that our leadership structure ensures a greater role for the non-management directors in the oversight of our Company and active participation of the independent directors in setting agendas and establishing priorities and procedures for the work of our Board.

35

Risk is inherent with every business, and how well a business manages risk can ultimately determine the business' success. As a medical device manufacturer, we face a number of risks, including risks related to patient safety, our financial condition, development and commercialization activities, operations, strategic direction, and intellectual property.

Management is responsible for the day-to-day management of risks we face, while our Board, as a whole and through its committees, has responsibility for the oversight of risk management. In the Board's risk oversight role, our Board has the responsibility to oversee that the risk management processes designed and implemented by management are adequate and functioning as designed.

The role of the Board in overseeing the management of our risks is conducted primarily through committees of the Board, as disclosed in the descriptions of each of the committees above and in the charters of each of the committees. The full Board (or the appropriate committee in the case of risks that are under the purview of a particular committee) discusses with management our major risk exposures, their potential impact on us, and the steps we take to manage them. When a committee is responsible for evaluating and overseeing the management of a particular risk or risks, the chairperson of the relevant committee reports on the discussion to the full Board during the committee reports portion of the next Board meeting. This process enables the Board and its committees to coordinate the risk oversight role, particularly with respect to risk interrelationships.

Enterprise Risk Management Policy

In support of our risk management strategy, we have adopted an Enterprise Risk Management Policy (the "ERM Policy"). The ERM Policy governs our risk management practices and establishes responsibilities and processes for the identification, classification, analysis, treatment/mitigation, prevention and governance of all risks to us - defined as anything that could reasonably be expected to have a material adverse impact on the achievement of our strategic objectives and operational goals. The goal of the ERM Policy is to ensure that risks and related exposures are aligned with our strategic objectives, as well as risk tolerances set by the Board. The ERM policy is implemented through a framework guided by internal key principles as well as those outlined by the Committee of Sponsoring Organizations of the Treadway Commission.

Audit Committee

The members of our Audit Committee include Milena Alberti-Perez (Chair),Omar Ishrak, and Michael Davin, each of whom can read and understand fundamental financial statements. The Board has concluded that each member of the Audit Committee is independent under the rules and regulations of the SEC and the listing standards of the NYSE applicable to Audit Committee members. Each of Milena Alberti-Perez and Michael Davin qualify as an audit committee financial expert within the meaning of SEC regulations and meet the financial literacy requirements of the NYSE.

Our Audit Committee assists the Board with its oversight of the following:

the integrity of our financial statements;
our compliance with legal and regulatory requirements;
the qualifications, independence, and performance of our independent registered public accounting firm; and
the design and implementation of our internal audit function, and our risk assessment and risk management activities.

Narrative to Summary Compensation Table

Base Salaries

We use base salaries to recognize the experience, skills, knowledge, and responsibilities required of all our employees, including our Named Executive Officers. Base salaries are reviewed annually and adjusted from time to time to align salaries with market levels after taking into account individual responsibilities, performance, and experience. For the year ended December 31, 2023, the annual base salaries for each of Dr. Gaur and Mr. Geberth were initially $303,850 and $328,660, respectively, and were reduced to $36,000 from April 15, 2023 to July 31, 2023 in order to preserve our cash prior to the consummation of the Business Combination. Effective as of the closing of the Business Combination, the annual base salaries of Dr. Gaur and Mr. Geberth were increased to $620,000 and $425,000, respectively. For the year ended December 31, 2023, Mr. Chardon was paid base annual consulting fees equal to €340,000.

Non-equity Incentive Plan Compensation

Each of Dr. Gaur and Mr. Geberth are eligible to earn a performance-based annual cash bonus based on achievement of pre-established company and individual performance criteria established by our Board or Compensation Committee in their discretion. For 2023, the target annual bonus for each of Dr. Gaur and Mr. Geberth was initially equal to 30% of annual base salary, and was increased to 80% of Dr. Gaur's annual base salary and 50% of Mr. Geberth's annual base salary in connection with the closing of the Business Combination. No annual performance bonuses were paid for fiscal 2023. Mr. Chardon was eligible to earn quarterly commission compensation based on achievement of specified company performance criteria established by our Board or Directors in its discretion. For 2023, Mr. Chardon's target commission compensation was equal to 40% of his annual base consulting fees.

Equity Compensation

We believe that equity grants provide our executives with a strong link to our long-term performance, create an ownership culture and help to align the interests of our executives with our stockholders. In addition, we believe that equity grants with a time-based vesting feature promote executive retention because this feature incentivizes our executive officers to remain in our employment during the vesting period.

Independent Compensation Consultant

In assessing and setting the compensation of our Named Executive Officers, the Compensation Committee engaged Pearl Meyer & Partner LLC ("Pearl Meyer") as its independent compensation consultant. Pearl Meyer advises the Compensation Committee on best practices in executive compensation and provides the Compensation Committee with market data in an effort to ensure our compensation program is competitive and designed to attract, retain, and incentivize our Named Executive Officers.

Employment Arrangements with our Named Executive Officers

Effective upon the closing of the Business Combination, we entered into new employment agreements with each of Dr. Gaur and Mr. Geberth and a new corporate officer agreement with Mr. Chardon, which set forth the terms and conditions of each executive's employment or consulting relationship. The new agreements supersede and replace each NEO's prior employment or consulting arrangement and provide for specified payments and benefits in connection with a termination of the NEO's employment or consulting relationship in certain circumstances. Our goal in providing these severance payments and benefits is to offer sufficient cash continuity protection such that the NEOs will focus their full time and attention on the requirements of the business rather than the potential implications for their respective positions. We prefer to have certainty regarding the potential severance amounts payable to the NEOs, rather than negotiating severance at the time that a NEO's employment or other service relationship terminates. We have also determined that accelerated vesting provisions with respect to outstanding equity awards in connection with a qualifying termination of employment in certain circumstances are appropriate to encourage our NEOs to stay focused on the business in those circumstances, rather than focusing on the potential implications for them personally. The material terms of each NEO's employment or consulting arrangements are summarized below.

Employment Agreement with Dr. Shantanu Gaur

We have entered into an employment agreement with Dr. Gaur, effective August 1, 2023, pursuant to which we employ Dr. Gaur as our Chief Executive Officer on an "at will" basis. Dr. Gaur's employment agreement provides that his initial annual

Mr. Geberth is also eligible to participate in the employee benefit plans generally available to our employees, subject to the terms of such plans.

In the event of a termination of Mr. Geberth's employment by Allurion without "cause" (as defined in his employment agreement) or by his resignation for "good reason" (as defined in his employment agreement), subject to Mr. Geberth's execution and non-revocation of a separation agreement containing, among other things, a release of claims in favor of Allurion and its affiliates, Mr. Geberth will be entitled to receive (i) base salary continuation for nine months following his termination date, and (ii) subject to Mr. Geberth's election to receive continued health benefits under COBRA, payment of the full cost of such continuation coverage plus any administration fee until the earliest of (A) 12 months following termination; (B) the date he becomes eligible for group medical plan benefits under any other employer's group medical plan; or (C) the expiration of Mr. Geberth's COBRA health continuation period.

Additional Narrative Disclosure

Employee Benefits

Our Named Executive Officers who are employees are eligible to participate in our welfare benefit plans, including medical, dental, vision, basic life and accidental death & dismemberment, and short-term and long- term disability insurance benefits, in each case on the same basis as all of our other employees.

401(k) Plan

43

Allurion participates in the ADP TotalSource Retirement Savings Plan (the "401(k) Plan"), which provides eligible U.S. employees (including our Named Executive Officers who are employees) with an opportunity to save for retirement on a tax advantaged basis. Under the 401(k) Plan, eligible employees may defer eligible compensation subject to applicable annual contribution limits imposed by the Internal Code of 1986, as amended (the "Code"). Allurion's employees' contributions are allocated to each participant's individual account and employees may begin participating after an initial 90 day waiting period. Under the provisions of the 401(k) Plan, Allurion makes 2% matching contributions and may make discretionary non-matching contributions, as determined by our Board. The 401(k) Plan is intended to be qualified under Section 401(a) of the Code with the 401(k) Plan's related trust intended to be tax exempt under Section 501(a) of the Code. As a tax-qualified retirement plan, contributions to the 401(k) Plan and earnings on those contributions are not taxable to the employees until distributed from the 401(k) Plan.

Director Compensation Table

The following table sets forth information regarding the compensation awarded to, earned by, or paid to our non-employee directors for service on our Board during the year ended December 31, 2023.

Initial Award: The Director Compensation Policy provides that each non-employee director serving on our Board on August 1, 2023 and each new non-employee director later elected or appointed to our Board will be granted an initial, one-time restricted stock unit award with a value of $225,000 that will vest in equal annual installments over three years, subject to continued service as a director through each vesting date.

Annual Award: On the date of each annual meeting of stockholders, each continuing non-employee director (excluding any non-employee director that was initially elected or appointed to our Board within six months prior to such annual meeting) will receive an annual restricted stock unit award with a value of $150,000 that will vest in full on the earlier of the first anniversary of the date of grant and the date of the next annual meeting of stockholders, subject to continued service as a director through such vesting date unless the Board determines otherwise. The vesting of all outstanding initial restricted stock unit awards and annual restricted stock unit awards held by non-employee directors will fully accelerate upon a "sale event" (as defined in our 2023 Plan).

For purposes of determining the size of each restricted stock unit award, the Director Compensation Policy defines "value" as the product of (A) the average closing market price on the NYSE (or such other market on which our common stock is then principally listed) of one share of our common stock over the trailing 30-day period ending on the last day of the month immediately prior to the month of the grant date, and (B) the aggregate number of shares of our common stock underlying such award.

In addition, on October 18, 2017, the board of directors of Legacy Allurion granted Mr. Davin an option to purchase 90,000 shares of Legacy Allurion common stock under our 2010 Plan(as defined below), which was converted into an option to purchase 88,019 shares of common stock upon consummation of the Business Combination and which was fully vested as of October 18, 2021. On March 5, 2020, the board of directors of Legacy Allurion granted Mr. Davin an option to purchase 45,000 shares of Legacy Allurion common stock under our 2010 Plan, which was converted into an option to purchase 44,009 shares of common stock upon consummation of the Business Combination, and which vested with respect to twenty-five percent (25%) of the shares underlying such option on the one-year anniversary of the date of grant, and then vested in 36 equally monthly installments thereafter. Finally, on December 7, 2021, the board of directors of Legacy Allurion granted Mr. Davin an option to purchase 30,000 shares of Legacy Allurion common stock under our 2020 Plan (as defined below), which was converted into an option to purchase 29,339 shares of common stock upon consummation of the Business Combination, and which vested in equal monthly installments over two years.

RTW invested

50

an aggregate of $3.0 million in the Public Offering and the concurrent Private Placement of the Series A Preferred Stock and Private Placement Warrants. Because the NYSE deemed RTW an Active Related Party under NYSE listing rules, the purchase by RTW of shares of common stock and public warrants in the Public Offering was limited under NYSE rules to 1% of the outstanding shares of common stock immediately prior to the Public Offering. The remainder of such investment was in the Private Placement. The Public Offering and Private Placement closed on July 1, 2024.

Related Person Transaction Policy

We have adopted a written related person transaction policy that sets forth the following policies and procedures for the review and approval or ratification of related person transactions.

Under our policy, a "Related Person Transaction" is any transaction in which Allurion or any of its subsidiaries was, is or will be a participant, the amount of which involved exceeds $120,000, and in which any related person had, has or will have a direct or indirect material interest. A "Related Person" as defined in the policy means:

any person who is known by Allurion to be the beneficial owner of more than 5% of our voting stock; and

We also have policies and procedures designed to minimize potential conflicts of interest arising from any dealings we may have with our affiliates and to provide appropriate procedures for the disclosure of any real or potential conflicts of interest that may exist from time to time.

If a stockholder fails to comply with any applicable requirements of the Exchange Act, including, but not limited to, Rule 14a-19, such stockholder's proposed nomination or proposed business shall be deemed to have not been made in compliance with our Bylaws and will be disregarded.

Additional Information

We reserve the right to reject, rule out of order, or take other appropriate action with respect to any proposal that does not comply with the requirements outlined above or other applicable requirements. It is suggested that stockholders submit their proposals by certified mail, return receipt requested, or by electronic means that permit such stockholder to verify the date of delivery to the Company.

Additionally, if the nominating or proposing stockholder (or a qualified representative of the stockholder) does not appear at the 2025 Annual Meeting of Stockholders to present a nomination or any business, such nomination or business shall be disregarded, notwithstanding that proxies in respect of such vote may have been received by the Company. To be considered a qualified representative of the proposing stockholder, a person must be authorized by a written instrument executed by such stockholder or an electronic transmission delivered by such stockholder to act for such stockholder as proxy at the meeting, and such person must produce such written instrument or electronic transmission, or a reliable reproduction, to the presiding officer at the 2025 Annual Meeting of Stockholders.

Householding

The SEC's rules permit us to deliver a single set of proxy materials to one address shared by two or more of our stockholders with such stockholder's consent, if required. This delivery method is referred to as "householding" and can result in significant cost savings. To take advantage of this opportunity, we will deliver only one set of proxy materials to multiple stockholders who share an address and who have consented to such delivery, if required, unless and until we receive contrary instructions from the impacted stockholders prior to the mailing date. We agree to deliver promptly, upon written or oral request, a separate copy of the proxy materials, as requested, to any stockholder at the shared address to which a single copy of those documents was delivered.

If you prefer to receive separate copies of the proxy materials, contact Innisfree, our proxy solicitor, toll-free at (888) 750-9498 or collect at (212) 750-5833. Innisfree's address is 501 Madison Avenue, 20th Floor, New York, New York 10022.

TO

AMENDED AND RESTATED

CERTIFICATE OF INCORPORATION

OF

ALLURION TECHNOLOGIES, INC.

ALLURION TECHNOLOGIES, INC., a corporation organized and existing under the laws of the State of Delaware (the "Corporation"), hereby certifies as follows:

1. The name of the Corporation is Allurion Technologies, Inc. The date of the filing of its original Certificate of Incorporationwith the Secretary of State of the State of Delaware was January 25, 2023 under the name Allurion Technologies Holdings, Inc. The Amended and Restated Certificate of Incorporation was filed with the Secretary of State of the State of Delaware on July 31, 2024, and has been amended by a Certificate of Designations of Preferences, Rights and Limitations of Series A Non-Voting Convertible Preferred Stock filed with the Secretary of State of the State of Delaware on June 28, 2024 (the Amended and Restated Certificate of Incorporation, as so amended, the "Certificate of Incorporation").

2. This Certificate of Amendment hereby amends Article IV of the Certificate of Incorporation by adding the following paragraphs after the first paragraph of Article IV, as follows:

"Upon the filing and effectiveness (the "Effective Time") of this Certificate of Amendment pursuant to Section 242 of the General Corporation Law of the State of Delaware, each ( ) shares of Common Stock issued and outstanding (or held in treasury) immediately prior to the Effective Time (the "Old Common Stock") shall automatically without further action on the part of the Corporation or any holder of Old Common Stock, be reclassified, combined, converted and changed into one (1) fully paid and nonassessable share of Common Stock (the "New Common Stock"), subject to the treatment of fractional share interests as described below (the "reverse stock split"). The reverse stock split shall not affect the total number of shares of capital stock, including the Common Stock, that the Corporation is authorized to issue, which shall remain as set forth under this Article IV.

The conversion of the Old Common Stock into New Common Stock will be deemed to occur at the Effective Time without any further action on the part of the Corporation or the holders of shares of New Common Stock and whether or not certificates representing such holders' shares prior to the reverse stock split are surrendered for cancellation. Upon the Effective Time, all references to "Common Stock" in this Certificate of Incorporation shall be to the New Common Stock.

The reverse stock split will be effectuated on a stockholder-by-stockholder (as opposed to certificate-by-certificate) basis, except that the reverse stock split will be effectuated on a certificate-by-certificate basis for shares held by registered holders, as applicable. From and after the Effective Time, certificates representing the Old Common Stock shall represent the number of shares of New Common Stock into which such Old Common Stock shall have been converted pursuant to this Certificate of Amendment. The Corporation shall not be obligated to issue new certificates evidencing the shares of New Common Stock outstanding as a result of the reverse stock split unless and until the certificates evidencing the shares held by a holder prior to the reverse stock split are either delivered to the Corporation or its current transfer agent, or the holder notifies the Corporation or such transfer agent that such certificates have been lost, stolen or destroyed and executes an agreement satisfactory to the Corporation to indemnify the Corporation from any loss incurred by it in connection with such certificates. Holders who otherwise would be entitled to receive fractional share interests of New Common Stock upon the effectiveness of the reverse stock split shall be entitled to receive a whole share of New Common Stock in lieu of any fractional share created as a result of such reverse stock split."

3. The stockholders of the Corporation have duly approved the foregoing amendment in accordance with the provisions of Section 211 and 242 of the General Corporation Law of the State of Delaware.

IN WITNESS WHEREOF, the Corporation has caused this Certificate of Amendment to be duly adopted and executed in its corporate name and on its behalf by its duly authorized officer as of this ____ day of _______________, 2024.
