Re: Securities Registered under Registration Statement on Form S-1
We have acted as counsel to you in connection with your filing of a Registration Statement on Form S-1 (as amended or supplemented, the “Registration Statement”) pursuant to the Securities Act of 1933, as amended (the “Securities Act”), relating to the registration of the sale by the selling securityholder listed in the Registration Statement under “Selling Securityholder” (the “Selling Securityholder”) of up to 30,191,900 shares (the “Shares”) of Common Stock, $0.0001 par value per share (“Common Stock”), of Allurion Technologies, Inc., a Delaware corporation (the “Company”), which are issuable to the Selling Securityholder pursuant to the terms of certain convertible notes due April 16, 2031 (the “Convertible Notes”).
We have reviewed such documents and made such examination of law as we have deemed appropriate to give the opinions set forth below. We have relied, without independent verification, on certificates of public officials and, as to matters of fact material to the opinions set forth below, on certificates of officers of the Company. For purposes of the opinion set forth below, we have assumed that before the Shares are issued, the Company does not issue shares of Common Stock or reduce the total number of shares of Common Stock that the Company is authorized to issue under its certificate of incorporation such that the number of unissued shares of Common Stock authorized under the Company’s certificate of incorporation is less than the number of Shares.
The opinion set forth below is limited to the Delaware General Corporation Law.
Based on the foregoing, we are of the opinion that the Shares have been duly authorized and, when issued and delivered upon the conversion of the Convertible Notes in accordance with the terms of the Convertible Notes, will be validly issued, fully paid and non-assessable.
This opinion letter and the opinion it contains shall be interpreted in accordance with the Core Opinion Principles as published in 74 Business Lawyer 815 (Summer 2019).
