Explanatory Note

The following constitutes Amendment No. 8 (“Amendment No. 8”) to the Schedule 13D filed with the Securities and Exchange Commission (the “SEC”) by Pfizer Inc. (“Pfizer” or the “Reporting Person”) on July 27, 2022, as amended by Amendment No. 1 on February 1, 2023, Amendment No. 2 on May 15, 2023, Amendment No. 3 on September 11, 2023, Amendment No. 4 on October 10, 2023, Amendment No. 5 on January 19, 2024, Amendment No. 6 on March 19, 2024, and Amendment No. 7 on March 22, 2024 (the “Schedule 13D”). This Amendment No. 8 amends and supplements the Schedule 13D as specifically set forth herein. Except as set forth herein, the Schedule 13D is unmodified. All capitalized terms contained herein but not otherwise defined shall have the meanings ascribed to such terms in the Schedule 13D. Information given in response to each item shall be deemed incorporated by reference in all other items, as applicable.

Item 2. Identity and Background.

The response set forth in Item 2 of the Schedule 13D is hereby amended by deleting Schedule I in its entirety and replacing it with Schedule I attached.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

Item 6 of the Schedule 13D is hereby supplemented as follows:

July 2024 Share Purchase Deed

On July 29, 2024, Pfizer and the Issuer entered into a share purchase deed (the “July 2024 Share Purchase Deed”) providing a framework for the Issuer to make certain off-market purchases of Ordinary Shares from Pfizer (or its nominees) on such number of occasions as Pfizer and the Issuer may agree either in conjunction with any future offer or sale of Ordinary Shares by Pfizer (or its nominees) (excluding, for the avoidance of doubt, any sale of Ordinary Shares to the Issuer pursuant to the July 2024 Share Purchase Deed) or by way of one or more standalone purchases by the Issuer from Pfizer (or its nominees). Off-market purchases consummated under the July 2024 Share Purchase Deed will take place at such prices, in such numbers and otherwise on the terms and conditions set forth in the July Share Purchase Deed and in certain notices contemplated thereby. The July 2024 Share Purchase Deed does not obligate either party to purchase or sell any Ordinary Shares and, in furtherance thereof, provides that either Pfizer or the Issuer (acting in its absolute discretion) may decline to participate in any proposed off-market purchase, in each case, subject to the terms and conditions set forth therein. Assuming the July 2024 Share Purchase Deed is not otherwise terminated in accordance with its terms, the term of the July 2024 Share Purchase Deed will continue until such time as the approval of the Issuer’s shareholders expires and is not renewed at a subsequent annual general meeting of the Issuer.

The foregoing description of the July 2024 Share Purchase Deed does not purport to be complete and is qualified in its entirety by reference to the actual terms of such agreement, which is filed as Exhibit 99.1 to this Amendment No. 8 and is incorporated by reference herein.

Item 7. Materials to Be Filed as Exhibits.

99.1 Share Purchase Deed, dated as of July 29, 2024, by and between Pfizer and the Issuer.*

* Filed herewith.
