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.
