Disclaimer

The following disclaimer applies to this presentation and the information provided therein, which has been prepared by Allwyn International AG ("AIAG" and, together with its subsidiaries and equity method investees, "Allwyn") and OPAP S.A. ("OPAP" and, tog ether with its subsidiaries, the "OPAP Group" and, together with certain subsidiaries and equity method investees of Allwyn to be contributed to the OPAP Group in connecti on with the transaction, "post - Transaction Allwyn"), and any other material distributed or statements made in connection with such presentation (the "Information"). You are therefore advised to carefully read the statements below before reading, accessing or making any other use of the Information .

The Information does not constitute or form part of, and should not be construed as, an offer to sell or issue or the solicit ati on of an offer to buy or acquire any securities of Allwyn or the OPAP Group, or any affiliate thereof in any jurisdiction wha tso ever. No part of the Information, nor the fact of its distribution, should form the basis of, or be relied on in connection with, any contract or commitment or investment decision wh atsoever. None of Allwyn, the OPAP Group or any of their respective advisers or representatives shall have any liability what soe ver for any loss whatsoever arising from any use of this presentation or its contents or otherwise arising in connection with this presentation (whether direct, indirect, con seq uential or other). Specifically, this presentation does not constitute a "prospectus" within the meaning of the U.S. Securiti es Act of 1933, as amended.

Certain information in this presentation and oral statements made in connection with this presentation are forward - looking. Forw ard - looking statements include, without limitation, statements regarding the estimated future financial performance, financial p osition and financial impacts of Allwyn, the OPAP Group and/or post - Transaction Allwyn. Words or phrases such as "anticipate," "objective," "may," "will," "might," "seem," " should," "could," "can," "intend," "expect," "believe," "estimate," "predict," "potential," "plan," "is designed to," "would, " "continue," "project," "possible," "seek," "future," "outlook," "strive," "strategy," "opportunity," "will continue," "will likely result" or similar expressions suggest future o utc omes but the absence of these words does not mean that a statement is not forward - looking. When Allwyn or OPAP discuss strategie s or plans, they are making projections and using forward - looking statements. These forward - looking statements include, but are not limited to, statements regarding estimates, fo recasts of other financial and performance metrics, projections of market opportunity and other characterizations of future e ven ts or circumstances, including any underlying assumptions. Forward - looking statements, financial projections and financial targets are based on the opinions and es timates of management at the date the statements are made and are subject to a variety of known and unknown risks and uncerta int ies and other factors that could cause actual events or results to differ materially from those anticipated in the forward - looking statements, financial projections an d financial targets. Although Allwyn and the OPAP Group believe that the expectations reflected in the forward - looking statement s and financial projections are reasonable, there can be no assurance that such expectations will prove to be correct. None of Allwyn's or the OPAP Group's independent auditor s, or any other independent accountants, have applied, examined or performed any procedures with respect to the financial target s, nor have they expressed any opinion or any other form of assurance on the financial targets or their achievability. These forward - looking statements are provided for illus trative purposes only and must not be relied on by an investor as a guarantee, an assurance, a prediction or a definitive sta tem ent of fact or probability. The financial targets constitute forward - looking statements and are not guarantees of future financial performance. Allwyn, the OPAP Group and post - Transaction Allwyn cannot guarantee future results, level of activity, performance or achievements and there is no representati on that the actual results achieved will be the same, in whole or in part, as those set out in the forward - looking statements, financial projections and financial targets, as a ctual events and circumstances are difficult or impossible to predict and may differ from assumptions.

While in some cases presented with numerical specificity, by their nature, forward - looking statements, financial projections and financial targets involve numerous assumptions, known and unknown risks and uncertainties, both general and specific, that co ntribute to the possibility that the predictions, forecasts, projections and other forward - looking information will not occur, which may cause Allwyn's, the OPAP Group's and post - Transaction Allwyn's actual performance and financial results in future periods to differ materially from any estimates or pr oj ections or targets of future performance or results expressed or implied by such forward - looking statements, financial projections and financial targets. Many actual events and circumstances are beyond the control of Allwyn, the OPAP Group and/or post - Transaction Allwyn. There may be additional risk s that either Allwyn and/or the OPAP Group presently knows, or that either Allwyn and/or the OPAP Group currently believes are immaterial, that could also cause actual res ults to differ from those contained in the forward - looking statements. The financial targets reflect Allwyn's and the OPAP Group 's subjective judgements in many respects and thus are susceptible to multiple interpretations and periodic revisions based on actual experience and business, economic, fi nan cial and other developments. Accordingly, such assumptions may change or may not materialize at all. The forward - looking stateme nts, financial projections and financial targets contained in this presentation are expressly qualified by this cautionary statement. While Allwyn, the OPAP Group and /or post - Transaction Allwyn may elect to update these forward - looking statements at some point in the future, except as required by applicable law, Allwyn, the OPAP Group and post - Transaction Allwyn specifically disclaim any obligation to update or revise publicly any forward - looking statements, wh ether as a result of new information, future events or otherwise, after the date on which the statements are made or to refle ct the occurrence of unanticipated events. None of Allwyn, the OPAP Group, post - Transaction Allwyn, or any of their respective affiliates, advisers, officers, directors or represe ntatives cannot give any assurance that the financial targets will be realized or that actual results will not vary significa ntl y from the financial targets. Additionally, some or all of the information in this presentation is or may be price - sensitive information and the use of such information may be regulated o r prohibited by applicable legislation, including securities laws related to insider dealing and market abuse. While all fina nci al, operational, industry and market projections, estimates and targets are necessarily speculative, Allwyn and the OPAP Group believe that the preparation of prospective fina nci al, operational, industry and market information involves increasingly higher levels of uncertainty the further out the proje cti on, estimate or target extends from the date of preparation. Actual results will differ, and may differ materially, from the results contemplated by the projected financial, op erational, industry and market information contained in this presentation, and the inclusion of such information in this pres ent ation should not be regarded as a representation by any person that the results reflected in such projections will be achieved.

In addition, this presentation contains certain unaudited pro rata financial information, which has been calculated as if eac h s ubsidiary or equity method investee of Allwyn were fully consolidated and then adjusted to reflect Allwyn's interest in such sub sidiary or significant equity method investee at the end of the relevant period.
