Item 5. Interest in Securities of the Issuer.

The first, second and third paragraphs of Item 5 of the Schedule 13D are hereby superseded by the following paragraphs:

(a)-(b) As of the date of this Schedule 13D, following the September 2024 Secondary Offering and the September 2024 Share Buyback (each as defined in Item 6), Pfizer is the beneficial owner of 1,361,709,764 Ordinary Shares (including interests in Ordinary Shares held indirectly through holdings of Restricted ADSs), which represents approximately 15.0% of the Issuer's outstanding Ordinary Shares. Pfizer's beneficial ownership is composed of (i) 197,228,952 Restricted ADSs held by Pfizer, representing 394,457,904 Ordinary Shares, issued under a restricted American Depositary Receipts facility with the Depositary, and (ii) 967,251,860 Ordinary Shares held on behalf of Pfizer by Pfizer's nominee. The beneficial ownership percentage reported herein was calculated based on 9,053,360,882 Ordinary Shares outstanding, as reported by the Issuer on its Form 6-K filed with the Securities and Exchange Commission on October 3, 2024.

(c) The responses to Items 4 and 6 of this Schedule 13D are incorporated by reference herein. Except as described herein, Pfizer has not acquired or disposed of any Ordinary Shares, Restricted ADSs, Unrestricted ADSs or other securities of the Issuer during the past 60 days.

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

The information set forth under the captions "July 2024 Share Purchase Deed" and "September 2024 Secondary Offering" within Item 6 of the Schedule 13D is hereby amended and restated as follows:

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.

Subject to the terms and conditions of the July 2024 Share Purchase Deed, in connection with the September 2024 Secondary Offering, the Issuer purchased Ordinary Shares from Pfizer, and Pfizer sold Ordinary Shares to the Issuer, having an aggregate purchase price of approximately £230 million (approximately $308 million at the pricing of the September 2024 Secondary Offering) (such transaction, the "September 2024 Share Buyback"). The purchase

price per Ordinary Share in the September 2024 Share Buyback was equal to the offering price per Ordinary Share in the September 2024 Secondary Offering. Accordingly, a total of approximately 60.5 million Ordinary Shares were repurchased by the Issuer pursuant to the September 2024 Share Buyback. The September 2024 Share Buyback was conditioned on, among other things, the closing of the September 2024 Secondary Offering. The September 2024 Share Buyback closed on October 3, 2024.

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 Amendment No. 8 and is incorporated by reference herein.

September 2024 Secondary Offering

On September 30, 2024, Pfizer, as the seller, entered into a secondary block trade agreement (the "September 2024 Block Trade Agreement") with Merrill Lynch International, Goldman Sachs International, Deutsche Bank AG, London Branch, HSBC Bank plc and RBC Europe Limited, as the lead managers (the "Lead Managers"), and the additional managers named therein (together with the Lead Managers, the "Managers"), pursuant to which the Lead Managers agreed, severally and not jointly or jointly and severally, to use their respective reasonable endeavors to procure purchasers for 540,000,000 Ordinary Shares (or such higher number as agreed between Pfizer and the Lead Managers) at a price to be determined pursuant to an accelerated book building process (the "September 2024 Secondary Offering"), and the Managers excluding the Lead Managers agreed, severally and not jointly or jointly and severally, to act as co-managers in connection with the September 2024 Secondary Offering. Pursuant to the terms of sale dated October 1, 2024 (the "Terms of Sale"), 640 million Ordinary Shares were sold at a price of 380 pence (approximately $5.09 at the pricing of the September 2024 Secondary Offering) per Ordinary Share. Such Ordinary Shares were sold in an unregistered offering pursuant to exemptions from registration under the Securities Act of 1933, as amended. The September 2024 Secondary Offering closed on October 3, 2024.

Pursuant to the September 2024 Block Trade Agreement, Pfizer undertook that it would not, and would procure that the members of its Group (as defined therein) would not, without the prior written consent of Merrill Lynch International and Goldman Sachs International, directly or indirectly, offer, sell, contract to sell, pledge, grant any option over or otherwise dispose of any equity securities of the Issuer or any securities convertible into, or exercisable, or exchangeable for, equity securities of the Issuer, or publicly announce an intention to effect any such transaction, for a period beginning on September 30, 2024 and ending 60 days after the closing of the September 2024 Secondary Offering, subject to certain exceptions.

The foregoing descriptions of the September 2024 Block Trade Agreement and the Terms of Sale do not purport to be complete and are qualified in their entirety by reference to the actual terms of such agreements, which are filed as Exhibit 99.1 and Exhibit 99.2 to Amendment No. 9 and are incorporated by reference herein.
