The contents of this Announcement have been prepared by and are the sole responsibility of the Company. None of the Underwriters or any of their respective subsidiary undertakings, affiliates or any of their respective directors, officers, employees, advisers, agents, alliance partners or any other entity or person accepts any responsibility or liability whatsoever for, or makes any representation, warranty or undertaking, express or implied, as to the truth, accuracy, completeness or fairness of the information or opinions in this Announcement (or whether any information has been omitted from the Announcement) or any other information relating to the group, its subsidiaries or associated companies, whether written, oral or in a visual or electronic form, and howsoever transmitted or made available or for any loss howsoever arising from any use of this Announcement or its contents or otherwise arising in connection therewith. Accordingly, the Underwriters disclaim, to the fullest extent permitted by applicable law, all and any liability, whether arising in tort or contract or that they might otherwise be found to have in respect of this Announcement and/or any such statement.

To the extent available, the industry, market and competitive position data contained in this Announcement are derived from official or third-party sources. Third-party industry publications, studies and surveys generally indicate that the data they contain have been obtained from sources believed to be reliable, but no representation is made as to the accuracy or completeness of such data. Although the Company reasonably believes that each of these publications, studies and surveys has been prepared by a reputable source, neither the Company, the Selling Shareholder, the Financial Adviser, the Underwriters, any of their respective subsidiaries or affiliates, nor any of their respective directors, employees, advisers or agents has independently verified the data contained therein. Accordingly, undue reliance should not be placed on any industry, market or competitive position data contained in this Announcement.

In addition to financial information prepared in accordance with International Financial Reporting Standards (“IFRS”), this Announcement contains certain non-IFRS measures, which the Company considers to be alternative performance measures (“APMs”) for the purposes of Commission Delegated Regulation (EU) 2019/979 of 14 March 2019 and as defined in the European Securities and Markets Authority's Guidelines on Alternative Performance Measures of 5 October 2015 (ESMA/2015/1415). These APMs are performance measures that have been calculated using the Company's financial information but are not defined or detailed in the applicable financial reporting framework and therefore have not been audited and are not susceptible to audit in full. The APMs are used to provide a better understanding of the Company's results, but should be considered only as additional information and in no case as a substitute for financial information prepared in accordance with IFRS. In addition, the way in which the Company defines and calculates these APMs may differ from the way in which other companies using similar measures calculate them, and therefore they may not be comparable.

Information to distributors: Solely for the purposes of the product governance requirements contained within: (a) EU Directive 2014/65/EC on markets in financial instruments, as amended (“MiFID II”); (b) Articles 9 and 10 of Commission Delegated Directive (EU) 2017/593 supplementing MiFID II; and (c) local implementing measures (together, the “MiFID II Product Governance Requirements”) and in Chapter 3 of the FCA Handbook Product Intervention and Product Governance Sourcebook (the “UK Product Governance Requirements”, together with the MiFID II Product Governance Requirements, the “Product Governance Requirements”), and disclaiming all and any liability, whether arising in tort, contract or otherwise, which any “manufacturer” (for the purposes of the Product Governance Requirements) may otherwise have with respect thereto, the Shares have been subject to a product approval process, which has determined that such Shares are: (i) compatible with an end target market of retail investors and investors who meet the criteria of qualified investors, as defined in MiFID II; (ii) compatible with an end target market of retail investors and investors who meet the criteria of professional clients and eligible counterparties, as respectively defined in Chapter 3 of the FCA Handbook Conduct of Business Sourcebook (“COBS”) and (iii) eligible for distribution through all distribution channels as are permitted by the Product Governance Requirements (the “Target Market Assessment”).

Notwithstanding the Target Market Assessment, distributors should note that: the price of the Shares may decline and investors could lose all or part of their investment; the Shares offer no guaranteed income and no capital protection; and an investment in the 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 Target Market Assessment is without prejudice to the requirements of any contractual, legal or regulatory selling restrictions in relation to the Offering. Furthermore, it is noted that, notwithstanding the Target Market Assessment, the Underwriters will only procure investors who meet the criteria of qualified investors. For the avoidance of doubt, the Target Market Assessment does not constitute: (a) an assessment of suitability or appropriateness for the purposes of MiFID II; 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 Shares in the Offering. Each distributor is responsible for undertaking its own target market assessment in respect of the Shares in the Offering (by either adopting the Target Market Assessment or redefining it under the MiFID II Product Governance Requirements) and determining appropriate distribution channels.
