UK Retail Investors will be advised of the minimum application amount applicable to their potential investment in the UK Retail Offer by their Participating Intermediary.
There is no minimum allocation of Shares to the UK Retail Offer and the Company may decide not to allocate any Shares to the UK Retail Offer.
Investors should make their own investigations into the merits and risks of an investment in the Company. Nothing in this announcement amounts to a recommendation to invest in the Company or to investment, financial, tax or legal advice.
It should be noted that an application for Shares and investment in the Company carries a number of risks. Investors in any doubt about participating in the UK Retail Offer or investing in the Shares (or the implications of doing so) should contact a retail intermediary, investment platform, solicitor, accountant or other financial adviser.

This announcement may contain forward-looking statements, which statements involve substantial risks and uncertainties about the Company and its industry. These statements may relate to, but are not limited to, the Company’s future financial condition or results of operations, business strategy and plans for growth, future capital expenditures, technological capabilities, strategic relationships, and objectives of management for future operations. In some cases, you can identify forward-looking statements because they contain words such as “may”, “will”, “should”, “expect”, “plan”, “anticipate”, “could”, “intend”, “target”, “project”, “contemplate”, “believe”, “estimate”, “predict”, “potential” or “continue” or the negative of these words or other similar terms or expressions that concern the Company’s expectations, strategy, plans or intentions. You should not rely upon forward-looking statements as predictions of future events.

The outcomes of the events described in these forward-looking statements are subject to risks, uncertainties, and other factors that may cause the Company’s actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements.
Moreover, the Company operates in a very competitive and rapidly changing environment. New risks and uncertainties emerge from time to time, and it is not possible for the Company to predict all risks and uncertainties that could have an impact on the forward-looking statements contained in this announcement. The Company cannot assure you that the results, events, and circumstances reflected in the forward-looking statements will be achieved or occur, and actual results, events, or circumstances could differ materially from those described in, or implied by, the forward-looking statements. Neither the Company nor any other person assumes responsibility for the accuracy and completeness of any of these forward-looking statements. Moreover, the forward-looking statements made in this announcement relate only to events as of the date on which the statements are made. The Company undertakes no obligation to update any forward-looking statements made in this announcement to reflect events or circumstances after the date of this announcement or to reflect new information or the occurrence of unanticipated events, except as required by law. The Company may not actually achieve the plans, intentions or expectations disclosed in its forward-looking statements and you should not place undue reliance on the forward-looking statements. The forward-looking statements do not reflect the potential impact of any future acquisitions, mergers, dispositions, joint ventures, or investments the Company may make. In addition, statements that “we believe” and similar statements reflect the Company’s beliefs and opinions on the relevant subject.
