Item 4. Purpose of the Transaction.

The disclosure in Item 3 and in Item 6 below is incorporated herein by reference.

On April 16, 2024, the board of directors of the Issuer (the “Board”), upon the recommendation of the Nominating and Corporate Governance Committee of the Issuer (the “NCGC”), appointed Felix J. Baker, a managing member of the Adviser GP, to the Board, effective as of April 18, 2024. As an independent director, Felix J. Baker will serve as a Class I director and serve as a member of the NCGC and the Scientific Committee until the Issuer’s 2026 annual general meeting of shareholders and until his successor has been duly elected and qualified or until his earlier death, resignation or removal. 

In conjunction with his appointment to the Board on April 18, 2024, the Issuer granted Felix J. Baker 24,000 options to purchase American Depositary Shares, each representing one Ordinary Share (“ADS”) at an exercise price of $21.82 per share which vest in 3 equal annual installments over a three-year period commencing on April 18, 2025, subject to continued service throughout the applicable vesting dates and expire on April 18, 2034 (“Share Options”), none of which will vest within sixty days following the date of this filing. In conjunction with his appointment to the Board, Felix J. Baker also received 12,000 restricted stock units (each, an “RSU”) which vest into ADS in three equal annual installments over a three-year period commencing on April 18, 2025, subject to continued service throughout the applicable vesting dates. The policies of the Funds and the Adviser do not permit managing members of the Adviser GP to receive compensation for serving as a director of the Issuer, and the Funds are instead entitled to the pecuniary interest in any compensation received for Felix J. Baker’s service on the Board.

The Funds hold securities of the Issuer for investment purposes. The Reporting Persons or their affiliates may purchase additional securities or dispose of securities in varying amounts and at varying times depending upon the Reporting Persons’ continuing assessments of pertinent factors, including the availability of Ordinary Shares or ADS or other securities for purchase at particular price levels, the business prospects of the Issuer, other business investment opportunities, economic conditions, stock market conditions, money market conditions, the attitudes and actions of the Board and management of the Issuer, the availability and nature of opportunities to dispose of securities of the Issuer and other plans and requirements of the particular entities.  The Reporting Persons may discuss items of mutual interest with the Issuer’s management, other members of the Board and other investors, which could include items in subparagraphs (a) through (j) of Item 4 Schedule 13D.

Depending upon their assessments of the above factors, the Reporting Persons or their affiliates may change their present intentions as stated above and they may assess whether to make suggestions to the management of the Issuer regarding financing, and whether to acquire additional securities of the Issuer, including Ordinary Shares or ADS (by means of open market purchases, privately negotiated purchases, exercise of some or all of the Share Options, conversion of Non-Voting Ordinary Shares (as defined in Item 5), or otherwise) or to dispose of some or all of the securities of the Issuer, including Ordinary Shares or ADS, under their control. Except as otherwise disclosed herein, at the present time, the Reporting Persons do not have any plans or proposals with respect to any extraordinary corporate transaction involving the Issuer including, without limitation, those matters described in subparagraphs (a) through (j) of Item 4 of Schedule 13D.

Item 5. Interest in Securities of the Issuer.

The disclosure in Item 4 is incorporated by reference herein.

(a) and (b) Items 7 through 11 and 13 of each of the cover pages of this Schedule 13D are incorporated herein by reference. Set forth below is the aggregate number of Ordinary Shares and ADS directly held by each of 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 Non-Voting Ordinary Shares (as defined below), subject to the limitations on conversion described below.

The non-voting Ordinary Shares (“Non-Voting Ordinary Shares”) are only convertible on a 1-for-1 basis into Ordinary Shares 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 (“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. The Reporting Persons notified the Issuer of an increase in the Beneficial Ownership Limitation from 9.99% to 19.9% on April 16, 2024. This increase in the Beneficial Ownership Limitation will take effect on June 16, 2024.

The Adviser has voting and investment power over the Share Options, Ordinary Shares underlying such Share Options, Ordinary Shares received from the exercise of Share Options, RSUs and Ordinary Shares received from the vesting of RSUs by Felix J. Baker received as directors’ compensation. The Adviser GP, and Felix J. Baker and Julian C. Baker as managing members of the Adviser GP, may be deemed to have the power to vote or direct the vote of and the power to dispose or direct the disposition of the Share Options, Ordinary Shares received from the exercise of Share Options, Ordinary Shares underlying such Share Options, RSUs and Ordinary Shares received from the vesting of RSUs held by Felix J. Baker received as director’s compensation.

On March 6, 2024, 667 and Life Sciences acquired 173,300 and 1,774,700 ADS for $0.01 per ADS from the exercise of 1,733 and 17,747 European-style call options (“European Call Options”), respectively.

On April 15, 2024, 667 and Life Sciences converted 70,608 and 754,810 Ordinary Shares, respectively, into 70,608 and 754,810 ADS, respectively.

(c) The information set forth in Item 4 is hereby incorporated by reference into this Item 5(c). The following transactions in ADS were effected by the Funds during the sixty days preceding the filing of this statement using their working capital.  All transactions were effected in the over-the-counter market directly with a broker-dealer. The below transactions were traded in multiple transactions at varying prices; the prices indicated in the tabular data below reflect the weighted average prices of the ADS purchased on each date. The Reporting Persons undertake to provide the staff of the Securities and Exchange Commission (the “Staff”), upon request, full information regarding the number of the prices, quantities, and counterparties of each transaction. Except as disclosed herein, none of the Reporting Persons or their affiliates has effected any other transactions in securities of the Issuer during the past 60 days.

Registration Rights Agreement

On April 18, 2024, the Funds entered into a registration rights agreement (the “Registration Rights Agreement”) with the Issuer pursuant to which the Funds are entitled to certain resale registration rights with respect to the Ordinary Shares, ADS, and any Ordinary Shares or ADS issued or issuable upon the exercise or conversion of any securities of the Issuer, in each case that were then held or are thereafter acquired by the Funds (collectively, the “Registrable Securities”).

Under the Registration Rights Agreement, following a request by any of the Funds, the Issuer is obligated to file, as soon as reasonably practicable following such demand and in any event within sixty days of such demand, a resale registration statement on Form S-3, or other appropriate form, covering the resale of Registrable Securities held by the Funds (the “Resale Registration Shelf”), and to use its reasonable best efforts to keep the Resale Registration Shelf effective until the earlier of such time that (i) all Registrable Securities covered by the Resale Registration Shelf have been sold or may be sold freely without limitations or restrictions as to volume or manner of sale pursuant to Rule 144 of the Securities Act of 1933, as amended, or (ii) all Registrable Securities covered by the Resale Registration Shelf otherwise cease to be considered Registrable Securities pursuant to the terms of the Registration Rights Agreement. Under the Registration Rights Agreement, the Funds have the right to one underwritten public offering per calendar year, but no more than three underwritten public offerings in total, and no more than two underwritten public offerings or block trades in any twelve-month period, to effect the sale or distribution of their Registrable Securities, subject to specified exceptions, conditions and limitations. The rights of the Funds under the Registration Rights Agreement will continue in effect for up to ten years following the date of the Registration Rights Agreement.
