In connection with the Offer, Goldman Sachs International, as Stabilising Manager, may (but will be under no obligation to), to the extent permitted by applicable law, over-allot Ordinary Shares up to a maximum of 15,000,000 Ordinary Shares (prior to any exercise of the Over-allotment Option (as defined below)) or effect other transactions with a view to supporting the market price of the Ordinary Shares at a level higher than that which might otherwise prevail in the open market for a period of no more than 30 calendar days after the date of commencement of conditional dealings of the shares on the London Stock Exchange. Such transactions may be effected on the London Stock Exchange, in the over-the-counter markets or otherwise. There is no obligation on the Stabilising Manager to undertake stabilisation transactions. Such transactions, if commenced, may be discontinued at any time without prior notice and must be brought to an end no later than 30 calendar days after the date of commencement of conditional dealings of the Ordinary Shares on the London Stock Exchange (the "Stabilisation Period"). In no event will measures be taken to stabilise the market price of the Ordinary Shares above the Offer Price. Save as required by law, the Stabilising Manager does not intend to disclose the extent of any stabilisation transactions under the Offer.

For the purposes of allowing the Stabilising Manager to cover short positions resulting from any such over-allocations and/or from sales of Ordinary Shares effected by it during the Stabilisation Period, it is expected that certain shareholders of the Company will grant to the Stabilising Manager the over-allotment option (the "Over-allotment Option"), pursuant to which the Stabilising Manager may purchase or procure purchasers for up to a maximum of 15,000,000 Ordinary Shares (the "Over-allotment Shares") at the Offer Price. The Over-allotment Option shall be exercisable in whole or in part, upon notice by the Stabilising Manager, at any time on or before the 30th calendar day after the commencement of conditional dealings in the Ordinary Shares on the London Stock Exchange. Any Over-allotment Shares made available pursuant to the Over-allotment Option will rank pari passu in all respects with the Ordinary Shares, including for all dividends and other distributions declared, made or paid on the Ordinary Shares, will be purchased on the same terms and conditions as the Ordinary Shares in the Offer and will form a single class for all purposes with the other Ordinary Shares.

For the avoidance of doubt, the contents of the Group's websites are not incorporated by reference into, and do not form part of, this announcement.

Information for Distributors

Solely for the purposes of the product governance requirements of Chapter 3 of the FCA Handbook Product Intervention and Product Governance Sourcebook (the "UK Product Governance Rules"), and disclaiming all and any liability, whether arising in tort, contract or otherwise, which any "manufacturer" (for the purposes of the UK Product Governance Rules) may otherwise have with respect thereto, the Ordinary Shares have been subject to a product approval process which has determined that the Ordinary Shares are: (i) compatible with an end target market of retail investors and investors who meet the criteria of professional clients as defined in Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the EUWA and eligible counterparties as defined in the FCA Handbook Conduct of Business Sourcebook ("COBS"); and (ii) eligible for distribution through all permitted distribution channels (the "UK Target Market Assessment"). Notwithstanding the UK Target Market Assessment, distributors should note that: the price of the Ordinary Shares may decline and investors could lose all or part of their investment; the Ordinary Shares offer no guaranteed income and no capital protection; and an investment in the Ordinary Shares is compatible only with investors who do not need a guaranteed income or capital protection, who (either alone or in conjunction with an appropriate financial or other adviser) are capable of evaluating the merits and risks of such an investment and who have sufficient resources to be able to bear any losses that may result therefrom. The UK Target Market Assessment is without prejudice to the requirements of any contractual, legal or regulatory selling restrictions in relation to the Global Offering. Furthermore, it is noted that, notwithstanding the UK Target Market Assessment, the Underwriters will only procure investors who meet the criteria of professional clients and eligible counterparties.

For the avoidance of doubt, the UK Target Market Assessment does not constitute: (a) an assessment of suitability or appropriateness for the purposes of Chapter 9A or 10A respectively of COBS; or (b) a recommendation to any investor or group of investors to invest in, or purchase, or take any other action whatsoever with respect to the Ordinary Shares.

Each distributor is responsible for undertaking its own target market assessment in respect of the Ordinary Shares and determining appropriate distribution channels.
