These forward-looking statements regarding future events and the future results of Advent and AMCI are based on current expectations, estimates, forecasts, and projections about the industry in which Advent operates, as well as the beliefs and assumptions of Advent's management. These forward-looking statements are only predictions and are subject to known and unknown risks, uncertainties, assumptions and other factors beyond Advent's or AMCI's control that are difficult to predict because they relate to events and depend on circumstances that will occur in the future. They are neither statements of historical fact nor promises or guarantees of future performance. Therefore, Advent's actual results may differ materially and adversely from those expressed or implied in any forward-looking statements and Advent therefore cautions against relying on any of these forward-looking statements. Factors that might cause or contribute to such differences include, but are not limited to: economic conditions globally; the impact of competition; political and economic developments in the countries in which Advent operates; regulatory developments in Greece, Europe and internationally; the COVID-19 pandemic; the inability for any reason to close the transactions contemplated by the merger agreement between Advent and AMCI; the inability to recognize the anticipated benefits of the proposed business combination between ACMI and Advent, which may be affected by, among other things, the amount of cash available following any redemptions by AMCI's stockholders; the ability to meet NASDAQ's listing standards following the consummation of the proposed business combination; costs related to the proposed business combination; Advent's ability to manage growth; Advent's ability to execute its business plans and the timing and costs of these plans; Advent's estimates of the size of the markets it serves; the rate and degree of market acceptance of Advent's products; rising costs or pricing pressures adversely affecting Advent's profitability, including sales and marketing expenses; expectations regarding capacity constraints; potential litigation involving AMCI or Advent; the validity or enforceability of Advent's intellectual property and Advent's compliance with the intellectual property rights of third parties; and other risks and uncertainties indicated from time to time in the definitive proxy statement to be delivered to AMCI's shareholders and related registration statement on Form S-4, including those set forth under "Risk Factors" therein, and other documents filed or to be filed with the SEC by AMCI. Any forward-looking statements made by or on behalf of Advent or AMCI speak only as of the date they are made. Neither Advent nor AMCI undertakes any obligation to update any forward-looking statements to reflect any changes in their respective expectations with regard thereto or any changes in events, conditions or circumstances on which any such statement is based. Accordingly, attendees and recipients should not place undue reliance on forward-looking statements due to their inherent uncertainty. In this presentation, Advent relies on and refers to information and statistics regarding industry data. Advent obtained this information and statistics from third-party sources, including reports by financial data firms and other firms. Advent has supplemented this information where necessary with information from discussions with its own internal estimates, taking into account publicly available information about other industry participants and Advent's management's best view as to information that is not publicly available. Such information has not been subject to any independent audit or review. To the extent available, the industry, market and competitive position data contained herein has come from official or third party sources. Third party industry publications, studies and surveys generally state that the data contained therein has been obtained from sources believed to be reliable, but that there is no guarantee of the accuracy or completeness of such data. While Advent reasonably believes that each of these publications, studies and surveys has been prepared by a reputable party, neither Advent nor AMCI nor any of their respective directors, officers, employees, agents, affiliates, advisors or agents, have independently verified the data contained therein. In addition, certain industry, market and competitive position data contained herein come from Advent's internal research and estimates based on the knowledge and experience of Advent's management in the markets in which Advent operates. While Advent reasonably believes that such research and estimates are reasonable, they, and their underlying methodology and assumptions, have not been verified by any independent source for accuracy or completeness and are subject to change. Accordingly, reliance should not be placed on any of the industry, market or competitive position data contained in such information and no representation or warranty (express or implied) is given that such data is correct or complete. In connection with the proposed business combination between AMCI and Advent and related transactions, AMCI will file preliminary and definitive proxy statements and a registration statement on Form S-4 with respect to the proposed business combination and related matters with the SEC, and will mail a definitive proxy statement and other relevant documents to its stockholders. Investors and security holders of AMCI are advised to read, when available, the preliminary proxy statement and registration statement, and amendments thereto, and the definitive proxy statement in connection with AMCI's solicitation of proxies for its stockholders' meeting to be held to approve the proposed business combination and related matters and the related registration statement because the proxy statements and registration statement will contain important information about the proposed business combination and related transactions and the parties to such arrangements. The definitive proxy statement will be mailed to stockholders of AMCI as of a record date to be established for voting on the proposed business combination and related matters. Stockholders will also be able to obtain copies of the proxy statement, without charge, once available, at the SEC's website at www.sec.gov or by directing a request to: Investor Relations, AMCI Acquisition Corp., 975 Georges Station Road, Suite 900, Greensburg, PA 15601. AMCI, Advent, and their respective directors, executive officers and other members of their management and employees, may, under SEC rules, be deemed to be participants in the solicitation of proxies of AMCI's stockholders in connection with the proposed business combination and related transactions. Information concerning the interests of AMCI's and Advent's participants in the solicitation, which may, in some cases, be different than those of AMCI's and Advent's equity holders generally, will be available in the proxy statement relating to the proposed business combination and related matters to be filed by AMCI with the SEC.
