This presentation contains financial information prepared in accordance with U.S. generally accepting accounting principles ("GAAP") that have been extracted without material adjustment from audited GAAP financial statements and/or extracted or derived from unaudited accounting records that have been used to prepare GAAP financial statements. This presentation also contains certain non-GAAP financial measures which have not been and will not be audited. These non-GAAP financial measures are not recognized measures of financial performance or liquidity under GAAP, but are measures used by Advent's management to monitor the underlying performance of Advent's business and operations. These non-GAAP measures may not be indicative of Advent's historical operating results nor are such measures meant to be predicative of future results. These measures and ratios may not be comparable to those used by other companies under the same or similar names. As such, undue reliance should not be placed on these non-GAAP financial measures.

This presentation contains financial forecasts with respect to Advent's estimated future performance. These forecasts have been prepared solely by Advent and have not been diligenced by AMCI. Neither AMCI's independent auditors nor the independent auditors of Advent audited, reviewed, compiled or performed any procedures with respect to the projections for the purpose of their inclusion in this Investor Presentation and, accordingly, neither of them expressed an opinion or provided any other form of assurance with respect thereto for the purpose of this presentation. None of these forecasts were prepared with a view toward compliance with the published guidelines of the SEC, PCAOB, GAAP or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of financial forecasts. These projections should not be relied upon as being necessarily indicative of future results. In this presentation certain of the above-mentioned projected financial information has been included (in each case, with an indication that the information is an estimate and is subject to the qualifications presented herein) for purposes of providing comparisons with historical data. The assumptions and estimates underlying the prospective financial information are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the prospective financial information. Accordingly, there can be no assurance that the prospective results are indicative of the future performance of Advent or AMCI or that actual results will not differ materially from those presented in the prospective financial information. Inclusion of the prospective financial information in this Investor Presentation should not be regarded as a representation by any person that the results contained in the prospective financial information will be achieved. The financial forecasts reflect assumptions that are subject to change, and there can be no assurance that AMCI's or Advent's financial condition or results of operations will be consistent with those set forth in such analyses and forecasts. www.advent.energy AMCI ADVENT Acquisition Corp. 2
