Transaction Details

Footnotes

Reported securities are represented by American Depositary Shares ("ADSs"), each of which represents eight (8) Ordinary Shares of the Issuer. | Represents Ordinary Shares of the Issuer acquired from the Reporting Person by means of a scheme of arrangement (the "Scheme of Arrangement") under Part 26 of the UK Companies Act 2006, pursuant to a transaction agreement, dated as of July 8, 2025 (the "Transaction Agreement"), by and among the Issuer, Merck Sharp & Dohme LLC, a New Jersey limited liability company ("Parent") and Vol Holdings LLC, a Delaware limited liability company and wholly owned subsidiary of Parent ("Bidco"). | At the effective time of the Scheme of Arrangement (the "Effective Time"), each holder of the Scheme Shares (as defined in the Scheme of Arrangement) became entitled to receive $13.375 in cash per Scheme Share, without interest and net of any applicable withholding taxes. Because each ADS represents a beneficial ownership interest in eight (8) Ordinary Shares of the Issuer, holders of ADSs as of the Effective Time became entitled to receive eight (8) times the foregoing cash amount, or $107 in cash, without interest and net of any applicable withholding taxes, per ADS (the "ADS Consideration"). | Pursuant to the terms of the Transaction Agreement, immediately prior to the Effective Time, each outstanding time-based restricted share unit award ("RSU Award"), unless agreed otherwise, became fully vested, and at the Effective Time, was automatically converted into the right to receive an amount in cash (without interest and subject to all required withholding taxes) equal to the product of (i) the aggregate number of ADSs underlying such RSU Award and (ii) the ADS Consideration. | Represents an award of RSUs covering ADSs, which is presented in terms of the equivalent number of Ordinary Shares underlying the ADSs. Each RSU represents a contingent right to receive one (1) ADS of the Issuer. Each ADS represents eight (8) Ordinary Shares of the Issuer. The RSUs have no expiration date. | These performance-based restricted share unit awards (the "PRSUs") were earned upon the determination by the Board of Directors of the Issuer that certain performance metrics had been achieved. Pursuant to the terms of the Transaction Agreement, immediately prior to the Effective Time, the PRSUs, unless agreed otherwise, became fully vested, and at the Effective Time, were automatically converted into the right to receive an amount in cash (without interest and subject to all required withholding taxes) equal to the product of (i) the aggregate number of ADSs underlying such PRSU Award and (ii) the ADS Consideration.
