| Item 4 | Ownership: |
Items 5 through 9 and 11 of each of the cover pages to this Amendment No. 2 are incorporated herein by reference.
Set forth below is the aggregate number of Ordinary Shares represented by American Depositary Shares of the Issuer (“ADS”) directly held by each of Baker Brothers Life Sciences, L.P. (“Life Sciences”) and 667, L.P. (“667”, and together with Life Sciences, the “Funds”) which may be deemed to be indirectly beneficially owned by the Reporting Persons, as well as Ordinary Shares that may be acquired upon conversion of Class A non-voting Ordinary Shares (“Non-Voting Ordinary Shares”) convertible at any time without consideration on a 1-for-1 basis, subject to the limitations on conversion described below. Each ADS represents one Ordinary Share of the Issuer.
The information set forth below is based on 39,166,581 Ordinary Shares outstanding as of September 30, 2023, as reported in Exhibit 99.2 of the Issuer’s Form 6-K filed with the Securities and Exchange Commission on November 13, 2023, plus 1,208,775 Ordinary Shares issuable upon the conversion of 1,208,775 Non-Voting Ordinary Shares, subject to the limitations on conversion described below, plus 407,592 ADS issued upon conversion of Non-Voting Ordinary Shares by the Funds on October 17, 2023. Such percentage figures are calculated in accordance with Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).
| Name | Number of Ordinary Shares we own or have the right to acquire within 60 days |
Percent of Class Outstanding |
||||||
| 667, L.P. | 254,292 | 0.6 | % | |||||
| Baker Brothers Life Sciences, L.P. | 3,057,275 | 7.5 | % | |||||
| Total | 3,311,567 | 8.1 | % | |||||
The Non-Voting Ordinary Shares are only convertible to the extent that after giving effect to such conversion the holders thereof, their affiliates and any persons who are members of a Section 13(d) group with the holders or their affiliates would beneficially own in the aggregate, for purposes of Rule 13d-3 under the Exchange Act, no more than 9.99% of the outstanding Ordinary Shares (the “Beneficial Ownership Limitation”). By written notice to the Issuer, the Funds may from time to time increase or decrease the Beneficial Ownership Limitation applicable to that Fund to any other percentage not in excess of 19.9%. Any such increase will not be effective until the 61st day after such notice is delivered to the Issuer. As a result of this restriction, the number of Ordinary Shares that may be issued upon conversion of the Non-Voting Ordinary Shares by the above holders may change depending upon changes in the outstanding Ordinary Shares.
Pursuant to the management agreements, as amended, among the Adviser, the Funds and their respective general partners, the Funds’ respective general partners relinquished to the Adviser all discretion and authority with respect to the investment and voting power of the securities held by the Funds and thus the Adviser has complete and unlimited discretion and authority with respect to the Funds’ investments and voting power over investments.
The Adviser GP, Felix J. Baker and Julian C. Baker as managing members of the Adviser GP, and the Adviser may be deemed to be beneficial owners of securities of the Issuer directly held by the Funds.
