(d)       During the last five years, none of the Reporting Persons has been convicted in any criminal proceeding (excluding traffic violations or similar misdemeanors).

 

(e)       During the last five years, none of the Reporting Persons has been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Mr. Anderson is a citizen of the United Kingdom. Mr. Theurillat is a citizen of the Swiss Confederation.

 

Item 3.Source and Amount of Funds or Other Consideration.

 

As described below in Item 4, on October 20, 2023, SC purchased a total of 1,200,000 of the Issuer’s American Depositary Shares (“ADS”), each ADS representing the right to receive one Ordinary Share, at $11.60 per share for an aggregate purchase price of $13,920,000. SC used its working capital to purchase the ADSs. In addition, SC used its working capital for the Ordinary Shares previously acquired by SC.

 

Item 4.Purpose of Transaction.

 

The Reporting Persons acquired their positions in the Ordinary Shares for investment purposes. The Reporting Persons acquired the Ordinary Shares and ADSs from the Issuer through a combination of private placements prior to the Issuer becoming a public company and the Issuer’s initial public offering (the “IPO”). On October 20, 2023, as part of the Issuer’s IPO which closed on October 24, 2023, SC purchased a total of 1,200,000 of the ADSs, at the IPO price ($11.60 per share), for an aggregate purchase price of $13,920,000. Prior to the IPO, SC purchased an aggregate of 4,064,739 Ordinary Shares at an aggregate purchase price of approximately €38,154,217.

 

Mr. Hong serves as a member of the Board of Directors of the Issuer, and, in such capacity, may have influence over the corporate activities of the Issuer, including activities which may relate to items described in subparagraphs (a) through (j) of Item 4 of Schedule 13D. In addition, Mr. Hong, in his capacity as a director, may be entitled to receive cash attendance fees.

 

 

Page 10 of 12

 

SC may, from time to time, acquire additional Ordinary Shares and/or ADSs or sell all or a portion of the Ordinary Shares and/or ADSs held by SC in the open market or in privately negotiated transactions, or may distribute the Ordinary Shares and/or ADSs held by SC to its unitholders. Any actions SC might undertake will be dependent upon its review of numerous factors, including, among other things, the market prices of the Ordinary Shares and ADSs, general market and economic conditions, ongoing evaluation of the Issuer’s business, financial condition, operations and prospects, the relative attractiveness of alternative business and investment opportunities, investors’ need for liquidity, and other future developments.

 

Except as described in this Schedule 13D, the Reporting Persons do not have any present plans or proposals that relate to or would result in any of the actions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D, although, the Reporting Persons, at any time and from time to time, may review, reconsider and change their position and/or change their purpose and/or develop such plans and may seek to influence management or the Board of Directors of the Issuer with respect to the business and affairs of the Issuer and may from time to time consider pursuing or proposing such matters with advisors, the Issuer or other persons.

 

Item 5.Interest in Securities of the Issuer.

 

As of October 27, 2023, SC held directly 5,264,739 Ordinary Shares representing approximately 8.0% of the Issuer’s outstanding Ordinary Shares and 6,948,613 voting rights representing approximately 9.5% of the Issuer’s outstanding voting rights. None of the other Reporting Persons hold any Ordinary Shares or ADSs directly. SP SAS is the management company of SC and may be deemed to have shared voting and investment control over the Ordinary Shares and ADSs held by SC. Each of Antoine Papiernik, Cédric Moreau, Kinam Hong, Joseph Anderson and Jacques Theurillat are the members of the investment committee of SC and may be deemed to have shared voting and investment control over the Ordinary Shares and ADSs held by SC. Each of such individuals disclaims beneficial ownership of such Ordinary Shares and ADSs except to the extent of their pecuniary interest therein.

 

The ownership percentages are based upon 65,943,541 of the Issuer’s Ordinary Shares outstanding (including the Underwriter’s option to purchase an additional 3,048,825 shares) immediately after the Issuer’s IPO, as set forth in the Issuer’s prospectus pursuant to Rule 424(b)(4), filed with the United States Securities and Exchange Commission on October 23, 2023 (the “Prospectus”). The voting percentages are based upon 73,017,358 voting rights outstanding immediately after the Issuer’s IPO (including the Underwriter’s option to purchase an additional 3,048,825 shares).

 

(a)See Rows 11 and 13 of the cover page for each of the Reporting Persons, which information is incorporated herein by reference.

SC agreed that, subject to specified limited exceptions, for a period of 90 days from the date of the Prospectus, it would not, without the prior written consent of Morgan Stanley & Co. LLC and Leerink Partners LLC, offer, sell, contract to sell, pledge or otherwise dispose of, including the filing of a registration statement in respect of, or hedge any of their Ordinary Shares or ADSs or any securities convertible into, or exercisable or exchangeable for Ordinary Shares or ADSs; subject to certain exceptions as set forth in a Lock-Up Agreement.
