The Fund directly holds (i) 41,666,665 Ordinary Shares (equivalent to 8,333,333 ADSs) and (ii) 13,439,785 warrants (“Warrants”) through which it has the right to acquire 13,439,785 Ordinary Shares(equivalent to 2,687,957 ADSs), subject to a Beneficial Ownership Blocker (as defined below).

 

 

The shares reported herein for the Reporting Persons represent (i) 41,666,665 Ordinary Shares (equivalent of 8,333,333 ADSs), and (ii) 6,933,556 Ordinary Shares (equivalent to 1,386,711 ADSs) that the Reporting Persons beneficially own based on the right to acquire, upon the exercise of the Warrants. The Warrants may be exercised for Ordinary Shares at the election of the holder, except that the agreement governing the terms of the exercise of the Warrants contains a provision (the “Beneficial Ownership Blocker”) which precludes the exercise of the Warrants to the extent that, following the exercise, the holder, together with its affiliates and any other person acting together with the holder as a “group” (as defined in the rules under the Securities Exchange Act of 1934 (the “Act”)), would beneficially own more than 9.99% of the Ordinary Shares outstanding (including any Ordinary Shares represented by ADSs).

 

The Reporting Persons are currently prohibited from exercising the Warrants to the extent that the exercise would result in beneficial ownership of more than 48,600,221 Ordinary Shares by the Reporting Persons.

 

The information required by this item with respect to each Reporting Person is set forth in Rows 5 through 9 and 11 of the cover page to this Schedule 13G/A. The beneficial ownership percentages reported are based on 479,555,139 outstanding Ordinary Shares (equivalent of 95,911,028 ADSs), as reported in the Issuer’s Registration Statement on Form F-3 filed on September 12, 2023, plus (ii) 6,933,556 Ordinary Shares (equivalent of 1,386,711 ADSs) of which the Reporting Persons may currently acquire beneficial ownership upon the exercise of the Warrant, as limited by the Beneficial Ownership Blocker.

 

RA Capital Healthcare Fund GP, LLC is the general partner of the Fund. The general partner of RA Capital is RA Capital Management GP, LLC, of which Dr. Kolchinsky and Mr. Shah are the controlling persons. RA Capital serves as investment adviser for the Fund and may be deemed a beneficial owner, for purposes of Section 13(d) of the Act, of any securities of the Issuer held by the Fund. The Fund has delegated to RA Capital the sole power to vote and the sole power to dispose of all securities held in the Fund’s portfolio, including the Issuer’s Ordinary Shares reported herein. Because the Fund has divested voting and investment power over the reported securities it holds and may not revoke that delegation on less than 61 days’ notice, the Fund disclaims beneficial ownership of the securities it holds for purposes of Section 13(d) of the Act. As managers of RA Capital, Dr. Kolchinsky and Mr. Shah may be deemed beneficial owners, for purposes of Section 13(d) of the Act, of any securities of the Issuer beneficially owned by RA Capital. RA Capital, Dr. Kolchinsky, and Mr. Shah disclaim beneficial ownership of the securities reported in this Schedule 13G/A other than for the purpose of determining their obligations under Section 13(d) of the Act, and the filing of this Schedule 13G/A shall not be deemed an admission that either RA Capital, Dr. Kolchinsky, or Mr. Shah is the beneficial owner of such securities for any other purpose.
