Item 4

Ownership:

 

Items 5 through 9 and 11 of each of the cover pages to this Amendment No. 3 are incorporated herein by reference.

 

Set forth below is the aggregate number of Ordinary Shares represented by American Depositary Shares (“ADS”) which may be deemed to be indirectly beneficially owned by the Reporting Persons, that may be acquired upon conversion of Ordinary Shares represented by ADS that may be acquired upon conversion of 6% convertible notes with a conversion price of 17.4 pence per Ordinary Share due August 3, 2023 (“Tranche 1 Notes”), subject to the limitations on conversion described below. Each ADS represents 5 Ordinary Shares of the Issuer.

 

 

The information set forth below is based on 643,204,794 Ordinary Shares outstanding as of June 9, 2023, as obtained in an email received from the Issuer on July 25, 2023, plus 14,604,391 Ordinary Shares represented by 2,920,878 ADS that may be acquired upon conversion of Tranche 1 Notes, subject to the limitations on conversion described below and 9,645,200 Ordinary Shares represented by 1,929,040 ADS issued in a conversion of Tranche 1 Notes by the Funds on July 21, 2023. Such percentage figures are calculated in accordance with Rule 13d-3 under the Securities Exchange Act of 1934, as amended.

 

Name		Number of Ordinary Shares we own or have the right to acquire within 60 days				Percent of Class Outstanding
667, L.P.			1,060,040				0.2	%
Baker Brothers Life Sciences, L.P.			13,544,351				2.0	%
Total			14,604,391				2.2	%

 

The Tranche 1 Notes are only convertible to the extent that upon giving effect or immediately prior to such conversion the holders thereof, their affiliates and any persons who are members of a Section 13(d) group with the holders or its affiliates would beneficially own in the aggregate, for purposes of Section 13(d) of the Exchange Act, no more than 9.99% of the outstanding Ordinary Shares after conversion (“Notes Beneficial Ownership Limitation”, and together with the Warrants Beneficial Ownership Limitation, the “Beneficial Ownership Limitations”). By written notice to the Issuer, the Funds may from time to time increase or decrease the Notes Beneficial Ownership Limitation applicable to that Fund to any other percentage not in excess of 19.99%. 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 exercise of the Tranche 1 Notes 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.
