    <div>&#160;</div>
    <div style="text-align: justify;">This Quarterly Report on Form 10-Q contains forward-looking statements, which reflect our current views with respect to, among other things, our operations and financial performance. All statements other than
      statements of historical facts contained in this Quarterly Report on Form 10-Q, including statements regarding our future results of operations and financial position, business strategy and plans and our objectives for future operations, are
      forward-looking statements. The words &#8220;believe,&#8221; &#8220;may,&#8221; &#8220;will,&#8221; &#8220;estimate,&#8221; &#8220;continue,&#8221; &#8220;anticipate,&#8221; &#8220;intend,&#8221; &#8220;expect,&#8221; &#8220;should,&#8221; &#8220;could,&#8221; &#8220;target,&#8221; &#8220;predict,&#8221; &#8220;seek&#8221; and similar expressions are intended to identify forward-looking statements. We
      have based these forward-looking statements largely on our current expectations and projections about future events and financial trends that we believe may affect our financial condition, results of operations, business strategy, short- and
      long-term business operations and objectives, and financial needs. These forward-looking statements are subject to a number of risks, uncertainties and assumptions, including those referenced in the section titled &#8220;Risk Factors,&#8221; which could cause
      actual results to differ materially. Moreover, we operate in a very competitive and rapidly changing environment and new risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all
      factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in or implied by any forward-looking statements we may make. In light of these risks,
      uncertainties and assumptions, the forward-looking events and circumstances discussed in this Quarterly Report on Form 10-Q may not occur and actual results could differ materially and adversely from those anticipated or implied in the
      forward-looking statements.</div>
    <div>&#160;</div>
    <div>Some of the key factors that could cause actual results to differ include:</div>

    <div>&#160;</div>
    <div style="text-align: justify;">This Quarterly Report on Form 10-Q contains our unaudited condensed consolidated financial statements for the three-month period ended March 31, 2021.</div>
    <div style="text-align: justify;">&#160;</div>
    <div style="text-align: justify;">We were originally incorporated in Delaware on June 18, 2018 under the name &#8220;AMCI Acquisition Corp.&#8221; as a special purpose acquisition company formed for the purpose of effecting a merger, capital stock exchange, asset
      acquisition, stock purchase, reorganization or other similar business combination with one or more target businesses. On November 20, 2018, we consummated our initial public offering (the &#8220;Initial Public Offering&#8221;), following which our shares began
      trading on the Nasdaq Global Market (&#8220;Nasdaq&#8221;).</div>
    <div style="text-align: justify;">&#160;</div>
    <div style="text-align: justify;">On February 4, 2021, we consummated the previously announced business combination (the &#8220;Business Combination&#8221;) pursuant to that certain Agreement and Plan of Merger, dated October 12, 2020, by and among AMCI
      Acquisition Corp. (the &#8220;Company&#8221;), AMCI Merger Sub Corp., a Delaware corporation and newly formed wholly-owned subsidiary of the Company (&#8220;Merger Sub&#8221;), AMCI Sponsor LLC (the &#8220;Sponsor&#8221;), solely in the capacity as the representative from and after the
      effective time of the Business Combination (as defined below) (the &#8220;Effective Time&#8221;) for the stockholders of the Company (other than the Advent stockholders) (the &#8220;Purchaser Representative&#8221;), Advent Technologies, Inc., a Delaware corporation
      (&#8220;Advent&#8221;), and Vasillios Gregoriou, solely in his capacity as the representative from and after the Effective Time for the Advent stockholders (the &#8220;Seller Representative&#8221;), as amended by Amendment No. 1 and Amendment No. 2 to the Agreement and Plan
      of Merger (the &#8220;Amendments&#8221; and as amended, the &#8220;Merger Agreement&#8221;), dated as of October 19, 2020 and December 31, 2020, respectively, by and among the Company, Merger Sub, Sponsor, Advent, and Seller Representative. In connection with the closing of
      the Business Combination (the &#8220;Closing&#8221;), we acquired 100% of the stock of Advent (as it existed immediately prior to the Closing) and its subsidiaries, changed our name from &#8220;AMCI Acquisition Corp.&#8221; to &#8220;Advent Technologies Holdings, Inc.&#8221; and
      changed the trading symbols of our common stock and warrants on Nasdaq from &#8220;AMCI&#8221; and &#8220;AMCIW&#8221; to &#8220;ADN&#8221; and &#8220;ADNWW,&#8221; respectively.</div>
    <div style="text-align: justify;">&#160;</div>
    <div style="text-align: justify;">For accounting purposes, the Business Combination is treated as a reverse acquisition and recapitalization, in which Advent is considered the accounting acquirer (and legal acquiree) and the Company is considered the
      accounting acquiree (and legal acquirer). Additionally, unless otherwise stated or the context indicates otherwise, with respect to the financial information contained in this Quarterly Report on Form 10-Q, including in &#8220;Part I, Item 1. Financial
      Statements&#8221; and the notes thereto and in &#8220;Part I, Item 2. Management&#8217;s Discussion and Analysis of Financial Condition and Results of Operations,&#8221; the financial information relating to the quarter ended March 31, 2020 are those of Advent and its
      subsidiaries, and for the quarter ended March 31, 2021, the financial information includes the financial information of Advent and its subsidiaries for the period prior to the Closing and the financial information of the Company and its subsidiaries
      for the period subsequent to the Closing. See Note 1 &#8220;Basis of Presentation in the accompanying unaudited condensed consolidated financial statements for additional information.</div>

      agreement (the &#8220;Agreement and Plan of Merger&#8221;), dated October 12, 2020, by and among AMCI, AMCI Merger Sub Corp., a Delaware corporation and newly formed wholly-owned subsidiary of AMCI (&#8220;Merger Sub&#8221;), AMCI Sponsor LLC (the &#8220;Sponsor&#8221;), solely in the
      capacity as the representative from and after the effective time of the Business Combination for the stockholders of AMCI (the &#8220;Purchaser Representative&#8221;), Advent Technologies, Inc., a Delaware corporation (&#8220;Legacy Advent&#8221;), and Vasillios Gregoriou,
      solely in his capacity as the representative from and after the effective time for the Legacy Advent stockholders (the &#8220;Seller Representative&#8221;), as amended by Amendment No. 1 and Amendment No. 2 to the Agreement and Plan of Merger, dated as of
      October 19, 2020 and December 31, 2020, respectively, by and among AMCI, Merger Sub, Sponsor, Legacy Advent, and Seller Representative. In connection with the closing of the Business Combination (the &#8220;Closing&#8221;), AMCI acquired 100% of the stock of
      Legacy Advent (as it existed immediately prior to the Closing) and its subsidiaries.</div>
    <div>&#160;</div>
    <div style="text-align: justify; color: rgb(0, 0, 0);">On the Closing Date, and in connection with the closing of the Business Combination, AMCI changed its name to Advent Technologies Holding, Inc. (the "Company" or "Advent"). Legacy Advent was deemed
      the accounting acquirer in the Business Combination based on an analysis of the criteria outlined in Accounting Standards Codification ("ASC") 805. This determination was primarily based on Legacy Advent's stockholders prior to the Business
      Combination having a majority of the voting interests in the combined company, Legacy Advent's operations comprising the ongoing operations of the combined company, Legacy Advent's board of directors comprising a majority of the board of directors of
      the combined company, and Legacy Advent's senior management comprising the senior management of the combined company. Accordingly, for accounting purposes, the Business Combination was treated as the equivalent of Legacy Advent issuing stock for the
      net assets of AMCI, accompanied by a recapitalization. The net assets of AMCI are stated at historical cost, with no goodwill or other intangible assets recorded.</div>
    <div>&#160;</div>
    <div style="text-align: justify; color: rgb(0, 0, 0);">While AMCI was the legal acquirer in the Business Combination, because Legacy Advent was deemed the accounting acquirer, the historical financial statements of Legacy Advent became the historical
      financial statements of the combined company, upon the consummation of the Business Combination. As a result, the unaudited condensed consolidated financial statements included in this report reflect (i) the historical operating results of Legacy
      Advent prior to the Business Combination; (ii) the results of the Company (combined results of AMCI and Legacy Advent) following the closing of the Business Combination; (iii) the assets and liabilities of Legacy Advent at their historical cost; and
      (iv) Company&#8217;s equity structure for all periods presented.</div>
    <div>&#160;</div>
    <div style="text-align: justify; color: rgb(0, 0, 0);">In accordance with guidance applicable to these circumstances, the equity structure has been restated in all comparative periods up to the Closing Date, to reflect the number of shares of the
      Company's common stock, $0.0001 par value per share ("Common Stock") issued to Legacy Advent's stockholders in connection with the recapitalization transaction. As such, the shares and corresponding capital amounts and earnings per share related to
      Legacy Advent Preferred Stock (&#8220;Preferred Series A&#8221; and &#8220;Preferred Series Seed&#8221;) and Legacy Advent common stock prior to the Business Combination have been retroactively restated as shares reflecting the exchange ratio established in the Business
      Combination Agreement. Activity within the statement of changes in stockholders' equity / (deficit) for the issuances of Legacy Advent's Preferred Stock, were also retroactively converted to Legacy Advent common stock. (Note 3)</div>

      their estimated fair values. The excess of the fair value of purchase consideration transferred over the fair values of these identifiable assets and liabilities is recorded as goodwill. In case the fair value of purchase consideration transferred is
      below fair values of these identifiable assets and liabilities, the Company recognizes a gain from a bargain purchase. Such valuations require management to make significant estimates and assumptions, especially with respect to intangible assets.
      Significant estimates in valuing certain intangible assets include, but are not limited to, future expected cash flows from acquired licenses, trade names, in process research and development ("R&amp;D"), useful lives and discount rates, patents,
      customer clientele, customer contracts and know-how. Management's estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from
      estimates. During the measurement period, the Company may record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period, any subsequent adjustments are
      recorded in the consolidated statement of operations.</div>

        used to determine the fair values and useful lives of identified intangible assets could change due to numerous factors, including product demand, market conditions, regulations affecting the business model of our operations, technological

        reporting units may be less than their carrying amounts. When indicators of impairment do not exist and certain accounting criteria are met, we are able to evaluate goodwill impairment using a qualitative approach. When necessary, our quantitative
        goodwill impairment test consists of two steps. The first step requires that we compare the estimated fair value of our reporting units to the carrying value of the reporting unit&#8217;s net assets, including goodwill. If the fair value of the reporting
        unit is greater than the carrying value of its net assets, goodwill is not considered to be impaired and no further testing is required. If the fair value of the reporting unit is less than the carrying value of its net assets, we would be required
        to complete the second step of the test by analyzing the fair value of its goodwill. If the carrying value of the goodwill exceeds its fair value, an impairment charge is recorded. Currently, we identify one reporting unit.</div>

      method by allowing a cumulative effect adjustment to the opening balance of retained earnings in the period of adoption. Additionally, ASU 2019-01, Codification Improvements to Topic 842, Leases and ASU 2020-02, Amendments to SEC Paragraphs Pursuant

      of AMCI. Immediately prior to the closing of the Business Combination, all shares of outstanding preferred stock Series A and preferred stock Series Seed of Legacy Advent were automatically converted into shares of the Legacy Advent's common stock.
      Upon the consummation of the Business Combination, each share of Legacy Advent common stock issued and outstanding was canceled and converted into the right to receive the amount of shares as determined based on the merger consideration of $250
      million minus the estimated consolidated indebtedness of Legacy Advent and its subsidiaries as of the consummation of the Business Combination, net of their estimated consolidated cash and cash equivalents (&#8220;Closing Net Indebtedness&#8221;) divided by
      $10.00. The Closing Net Indebtedness was based solely on estimates determined shortly prior to the closing and was not subject to any post-closing true-up or adjustment.</div>
    <div style="text-align: justify;">&#160;</div>
    <div style="text-align: justify;">Upon the closing of the Business Combination, AMCI's certificate of incorporation was amended and restated to, among other things, authorize the issuance of 111,000,000 shares, of which 110,000,000 shares are shares of
      common stock, par value $0.0001 per share and 1,000,000 shares are shares of undesignated preferred stock, par value $0.0001 per share.</div>
    <div style="text-align: justify;">&#160;</div>
    <div style="text-align: justify;">In connection with the execution of the Business Combination Agreement, AMCI entered into separate subscription agreements (each, a "Subscription Agreement") with a number of investors (each a "Subscriber"), pursuant
      to which the Subscribers agreed to purchase, and AMCI agreed to sell to the Subscribers, an aggregate of 6,500,000 shares of common stock (the "PIPE Shares"), for a purchase price of $10.00 per share and an aggregate purchase price of $65.0 million,
      in a private placement pursuant to the subscription agreements (the "PIPE"). The PIPE investment closed simultaneously with the consummation of the Business Combination.</div>
    <div style="text-align: justify;">&#160;</div>
    <div style="text-align: justify;">The Business Combination is accounted for as a reverse recapitalization in accordance with GAAP. Under this method of accounting, AMCI was treated as the "acquired" company for financial reporting purposes. See Note 1
      "Basis of Presentation" in the accompanying unaudited condensed consolidated financial statements for further details. Accordingly, for accounting purposes, the Business Combination was treated as the equivalent of Legacy Advent issuing stock for the
      net assets of AMCI, accompanied by a recapitalization. The net assets of AMCI are stated at historical cost, with no goodwill or other intangible assets recorded.</div>

      tax laws or rates is recognized in the interim period in which the change occurs. The computation of the annual estimated effective tax rate at each interim period requires certain estimates and judgments including, but not limited to, the expected
      operating income for the year, projections of the proportion of income earned and taxed in foreign jurisdictions, permanent differences between book and tax amounts, and the likelihood of recovering deferred tax assets generated in the current year.
      The accounting estimates used to compute the provision for income taxes may change as new events occur, additional information is obtained, or the tax environment changes.</div>

      Combination with Advent is both procedurally and substantively unfair and seeking to maintain the action as a class action and enjoin the Business Combination, among other things, without stating a specific amount of damages. The complaint does not
      provide detail as to how the proposed Business Combination is unfair, either procedurally or substantively, and we believe it has no merit. On February 10, 2021, a notice of voluntary discontinuance of the complaint was filed in the Supreme Court of

      <div><br>
      </div>
      <div style="text-align: justify; margin-bottom: 12pt;">Advent is an advanced materials and technology development company operating in the fuel cell and hydrogen technology space. Advent develops, manufactures and assembles the critical components
        that determine the performance of hydrogen fuel cells and other energy systems. Advent&#8217;s core product offering is the Membrane Electrode Assembly (MEA) at the center of the fuel cell. The Advent MEA, which derives its key benefits from the
        properties of Advent&#8217;s engineered membrane technology, enables a more robust, longer-lasting and ultimately lower-cost fuel cell product.</div>
      <div style="text-align: justify; margin-bottom: 12pt;">To date, Advent&#8217;s principal operations have been to develop and manufacture MEAs, and to design fuel cell stacks and complete fuel cell systems for a range of customers in the stationary power,
        portable power, automotive, aviation, energy storage and sensor markets. Advent has its headquarters in Boston, Massachusetts, a product development facility in Livermore, California, and an MEA assembly and production facility in Patras, Greece.
        In the third quarter of 2021, Advent anticipates opening its new research and development and manufacturing facility at Hood Park in Charlestown, Massachusetts. The majority of Advent&#8217;s current revenue derives from the sale of MEA&#8217;s as well as the
        sale of membranes and electrodes for specific applications in the iron flow battery and cellphone markets respectively. While MEA sales and associated revenues are expected to provide the majority of Advent&#8217;s future income, both of these markets
        remain commercially viable and have the potential to generate material future revenues based on Advent&#8217;s existing customers. Advent has also secured grant funding for a range of projects from research agencies and other organizations in the U.S.
        and Greece. Advent expects to continue to be eligible for grant funding based on its product development activities over the foreseeable future.</div>
      <div style="text-align: justify;">Historically, Advent has financed its operations through internal cashflows, grant income and private placements of equity and convertible notes. In the three months ended March 31, 2021, Advent generated revenue
        from product sales of approximately $1.5 million and incurred an operating&#160; loss of approximately $7 million. During the three months ended March 31, 2021, Advent received proceeds as a result of the Merger dated February 4, 2021 of approximately
        $140 million and recorded approximately $(12.2 million) in operating cashflow, resulting in a period end cash balance of approximately $125 million as of March 31, 2021.</div>

      <div style="margin-top: 6.75pt; font-weight: bold;">Business Combination and Public Company Costs</div>
      <div> <br>
      </div>
      <div style="text-align: justify;">On October 12, 2020, Advent Technologies, Inc. entered into the Merger Agreement with Advent Technologies Holdings, Inc. (formerly known as &#8220;AMCI&#8221;), a Delaware corporation, AMCI Merger Sub Corp., a newly-formed
        Delaware corporation and wholly-owned subsidiary of AMCI (&#8220;Merger Sub&#8221;), AMCI Sponsor LLC, a Delaware limited liability company (&#8220;Sponsor&#8221;), in its capacity as Purchaser Representative (the &#8220;Purchaser Representative&#8221;) and Vassilios Gregoriou, in
        the capacity as Seller Representative ( the &#8220;Seller Representative&#8221;), pursuant to which, effective February 4, 2021, Merger Sub merged with and into Advent Technologies Inc., with Advent Technologies Inc. surviving the Merger as a wholly-owned
        subsidiary of AMCI. Advent Technologies Inc. is deemed the accounting predecessor and the combined entity is the successor registrant with the SEC, meaning that Advent Technologies Inc.&#8217;s financial statements for previous periods will be disclosed
        in the registrant&#8217;s current and future periodic reports filed with the SEC.</div>
      <div><br>
      </div>
      <div style="text-align: justify;">While the legal acquirer in the Merger Agreement is AMCI, for financial accounting and reporting purposes under GAAP, we have determined that Advent is the accounting acquirer and the Business Combination will be
        accounted for as a &#8220;reverse recapitalization.&#8221; A reverse recapitalization does not result in a new basis of accounting, and the financial statements of the combined entity represent the continuation of the financial statements of Advent in many
        respects. Under this method of accounting, AMCI is treated as the acquired entity whereby Advent is deemed to have issued common stock for the net assets and equity of AMCI, consisting mainly of cash, accompanied by a simultaneous equity
        recapitalization of AMCI (the &#8220;Recapitalization&#8221;).</div>
      <div style="text-align: justify;"> <br>
      </div>
      <div style="text-align: justify;">Upon consummation of the Business Combination, the most significant change in Advent&#8217;s reported financial position and results has been an estimated increase in cash of approximately $140 million. Total direct and
        incremental transaction costs of AMCI and Advent, along with liabilities of AMCI paid off at the Closing, were approximately $23.6 million.</div>
      <div> <br>
      </div>
      <div style="text-align: justify;">As a consequence of the Business Combination, Advent became the successor to an SEC-registered and Nasdaq-listed company which has required and will require Advent to hire additional personnel and implement
        procedures and processes to address public company regulatory requirements and customary practices. Advent expects to incur additional annual expenses as a public company for, among other things, directors&#8217; and officers&#8217; liability insurance,
        director fees and additional internal and external accounting, legal and administrative resources, including increased audit and legal fees.</div>
      <div style="text-align: justify; margin-top: 6pt;">Additionally, Advent anticipates that its revenue, capital and operating expenditures will increase significantly in connection with its ongoing activities following the Business Combination, as
        Advent expects to:</div>

        submitted to the Greek government the group&#8217;s &#8220;White Dragon&#8221; proposal for the development of an innovative, integrated green hydrogen project in Greece. The proposal aims to transition Greece to clean energy production and transmission, with the
        ultimate goal of decarbonizing the energy system. The proposal plans to use large-scale renewable electricity to produce green hydrogen, which would then be stored and through high-temperature fuel cells developed and manufactured by the Company,
        to supply Greece with clean electricity, green energy and heat. The proposal includes for the study and construction of a dedicated hydrogen pipeline in Greece to link green hydrogen production with large hydrogen end users, as well as plans to
        implement the first widescale hydrogen fueled projects for the entire transportation section, including heavy duty trucks, trains and cars. The combined projected budget for the proposal, if approved in its entirety by the European and Greek
        authorities, is &#8364; 8.063 billion.</div>

      <div style="text-align: justify; margin-top: 13pt; font-weight: bold;">Key Factors Affecting Our Results</div>
      <div style="text-align: justify; margin-top: 13pt;">Advent believes that its performance and future success depend on several factors that present significant opportunities for Advent but also pose risks and challenges, including those discussed
        below.</div>
      <div style="font-style: italic; font-weight: bold; text-align: justify;"> <br>
      </div>
      <div style="font-style: italic; font-weight: bold; text-align: justify;">Increased Customer Demand</div>
      <div style="text-align: justify;"> <br>
      </div>
      <div style="text-align: justify;">Based on conversations with existing customers and incoming inquiries from new customers, Advent anticipates substantial increased demand for its MEAs from a wide range of customers as it scales up its production
        facilities and testing capabilities, and as the awareness of its MEA capabilities becomes widely-known in the industry. Advent expects both its existing customers to increase order volume, and to generate substantial new orders from major
        organizations, with some of whom it is already in discussions regarding prospective commercial partnerships and joint development agreements. As of March 31, 2021, Advent was still generating a low level of revenues compared to its future
        projections and has not made any commercial sales to these major organizations.</div>
      <div style="font-style: italic; font-weight: bold; text-align: justify;"> <br>
      </div>
      <div style="font-style: italic; font-weight: bold; text-align: justify;">Successful development of the Advanced MEA product</div>
      <div style="text-align: justify;"> <br>
      </div>
      <div style="text-align: justify;">Advent&#8217;s future success depends in large part on the increasing integration of the hydrogen fuel cell into the energy transition globally over the next decade. In order to become cost-competitive with existing
        renewable power generation and energy storage technology and achieve widespread adoption, fuel cells will need to achieve substantial improvement in the cost/kw performance ratio delivered to prospective fuel cell customers, predominantly OEMs,
        System Integrators and major energy companies. Advent expects to play an important enabling role in the adoption of hydrogen fuel cells, as its MEA technology is the critical determining factor in the cost/kw performance ratio of the fuel cells. In
        partnership with the Los Alamos National Laboratory, Advent is currently developing its next generation MEA technology (&#8220;Advanced MEA&#8221;) which is anticipated to deliver as much as three times the power output of its current MEA product. Whilst
        Advent is already projecting being able to pass through substantial cost benefits to its customers through economies of scale as it increases MEA production, the successful development of the Advanced MEA will be an important factor in delivering
        the required improvement in cost/kw performance to Advent&#8217;s customers.</div>

      <div style="text-align: justify;"> <br>
      </div>
      <div style="text-align: justify;">Advent&#8217;s unaudited condensed consolidated financial statements have been prepared in accordance with U.S. GAAP. The Company has determined that it operates in one reportable segment. See Note 1 &#8220;Basis of

      <div style="font-style: italic; font-weight: bold; text-align: justify;">Revenue, net</div>
      <div style="text-align: justify;"> <br>
      </div>
      <div style="text-align: justify;">Revenues consist of sales of goods (MEAs, membranes, fuel cell stacks, fuel cell systems and electrodes). Advent expects revenues to increase materially and be weighted towards MEA sales over time, in line with the
        projected increase in MEA production in response to customer demand.</div>
      <div style="text-align: justify; margin-top: 12.5pt; font-style: italic; font-weight: bold;">Cost of Revenues</div>
      <div style="text-align: justify;"> <br>
      </div>
      <div style="text-align: justify;">Cost of revenues consists of consumables, raw materials, processing costs and direct labor costs associated with the assembly and manufacture of MEAs, membranes, fuel cell stacks and electrodes. Advent expects cost
        of revenues to increase substantially in line with MEA production.</div>
      <div style="text-align: justify; margin-top: 12.5pt; font-style: italic; font-weight: bold;">Income from Grants</div>
      <div style="text-align: justify;"> <br>
      </div>
      <div style="text-align: justify;">Income from grants consists of cash subsidies received from research agencies and other national and international organizations in support of Advent&#8217;s research and development activities. Advent expects to continue
        to be eligible for grant income and remains in discussion with a number of prospective grantors in relation to a number of product development activities.</div>
      <div style="text-align: justify; margin-top: 12pt; font-style: italic; font-weight: bold;">Research and Development Expenses</div>
      <div><br>
      </div>
      <div style="text-align: justify;">Research and development expenses consist of costs associated with Advent&#8217;s research and development activities, such as laboratory costs and sample material costs. Advent expects its research and development
        activities to increase substantially as it invests in improved technology and products.</div>
      <div><br>
      </div>
      <div style="font-style: italic; font-weight: bold;">Administrative and Selling Expenses</div>
      <div><br>
      </div>
      <div style="text-align: justify;">Administrative and selling expenses consist of travel expenses, indirect labor costs, fees paid to consultants, third parties and service providers, taxes and duties, legal and audit fees, depreciation, business
        development salaries and limited marketing activities. Advent expects administrative and selling expenses to increase in line with MEA production and revenue as the business scales up, and as a result of operating as a public company, including
        compliance with the rules and regulations of the SEC, legal, audit, additional insurance expenses, investor relations activities and other administrative and professional services. Depreciation is also expected to increase as the Company invests in
        fixed assets in support of the scale-up of the business.</div>
      <div><br>

      <div>
        <div style="font-style: italic; font-weight: bold;">Other Income / Expenses</div>
        <div style="font-style: italic; font-weight: bold;"> <br>
        </div>
        <div style="text-align: justify;">Other operating income / (expenses) consist of additional de minimis incidental operating income / (expenses) incurred by the business. These income / (expenses) are expected to remain at a de minimis level in the
          future.</div>

      <div style="text-align: justify; font-style: italic; font-weight: bold;">Finance Costs</div>
      <div><br>
      </div>
      <div style="text-align: justify;">Finance costs consist mainly of bank charges. Finance costs are not anticipated to increase materially as Advent is not intending to take on substantial borrowings at the corporate level in the near future.</div>
      <div><br>
      </div>
      <div style="text-align: justify; font-style: italic; font-weight: bold;">Foreign exchange differences, net</div>
      <div><br>
      </div>
      <div style="text-align: justify;">Foreign exchange differences, net consists of foreign exchange gains and interest on deposits. As the Company scales up, its foreign exchange exposure is likely to increase given its revenues are denominated in both
        euros and dollars, and a substantial proportion of the Company&#8217;s costs are denominated in euros.</div>

      <div><br>
      </div>
      <div style="text-align: justify;">Income tax expense relates to the current income tax charge for the Company&#8217;s operations in Greece. This category is expected to increase in future as the Company generates sales and profits from its operations in
        both Greece and the U.S.</div>

        </div>
        <div style="text-align: justify; color: rgb(0, 0, 0); font-weight: normal;">The provisional value of $5 million of intangibles relates to trademarks, patents, customer relationships, customer contracts and know-how. Those intangibles mainly relate
          to definite-live intangible assets with estimated useful lives that vary between 3-10 years, with the exception of contract backlogs which are amortized over the remaining period of the contracts assumed based on income approach. During the
          period from acquisition and up to March 31, 2021, the Company has recognized in the condensed consolidated statement of operations amortization for those intangibles of $0.2 million. As noted earlier, the fair value of the acquired identifiable
          intangible assets is provisional pending receipt of the final valuations for these assets.</div>

      <div> <br>
      </div>
      <div>Our total revenue from product sales increased by approximately $1.4 million or 1,385% from approximately $0.1 million in the three months ended March 31, 2020 to approximately $1.5 million in the year ended March 31, 2021. The increase in
        revenue was related to increased demand from customers for Advent&#8217;s MEAs and other products, as a result of Advent&#8217;s customers increasing their own testing and usage of Advent&#8217;s products.</div>

      <div> <br>
      </div>
      <div style="text-align: justify;">Cost of revenues increased by approximately $0.3 million or 426% from approximately $0.1 million in the three months ended March 31, 2020 to approximately $0.3 million in the three months ended March 31, 2021. The
        increase in cost of revenues was directly related to the increased revenues across the two years and the requirement for increased production of MEAs and other products to satisfy customer demand. Gross margins were higher for the three months
        ended March 31, 2021, reflecting a more mature mix of revenues leading to more normalized pricing arrangements.</div>
      <div><br>
      </div>
      <div style="text-align: justify;">Our Gross Profit, which is Revenue, net minus the Cost of Revenue increased to $1.1 million in the three months ended March 31, 2021.</div>

        ended March 31, 2021 due to decreased activity in Advent&#8217;s research and development function as the business continues to look to develop and improve its product suite in order to respond to anticipated future customer demand.</div>

      <div> <br>

      <div style="text-align: justify;">Administrative and selling expenses were approximately $7.9 million in the three months ended March 31, 2021, and $0.3 million in the three months ended March 31, 2020. The increase was primarily due to one-time
        transaction costs post merger amounting to $5.9 million.</div>

      <div style="text-align: justify;">Change of fair value of warrant liability amounting to $9,765,625 was due to the change of fair value of the Private Placement Warrants and Working Capital Warrants from February 4, 2021 to March 31, 2021.</div>

      <div style="text-align: justify;"> <br>
      </div>
      <div style="text-align: justify;">Advent&#8217;s cash flows from operating activities reflect the income statement position adjusted for working capital movements in current assets and liabilities. As Advent grows, it expects that operating cash flows will
        be affected by increased working capital needs to support growth in personnel-related expenditures and fluctuations in accounts payable and other current assets and liabilities.</div>
      <div style="text-align: justify;"> <br>
      </div>
      <div style="text-align: justify;">Net cash used to operating activities was approximately $12.2 million for the three months ended March 31, 2021, which related to outflows in connection with one-time transactions costs, settlement of unpaid
        executive compensations and costs associated with insurances services and other consulting services.</div>
      <div style="text-align: justify;"> <br>
      </div>
      <div style="text-align: justify;">Net cash used in operating activities was approximately $0.3 million for the three months ended March 31, 2020, mainly related to payments to suppliers net of receipts from customers.</div>

      </div>
      <div style="text-align: justify;">Advent&#8217;s cash flows from investing activities represents the cash amount of $4 million paid at the consummation of the acquisition of UltraCell, LLC on February 18, 2021. Advent expects to invest substantially in
        fixed assets, plant and equipment in the near future as it executes its product development programs.</div>

      <div style="text-align: justify;"> <br>
      </div>
      <div style="text-align: justify;">A contract asset results when goods or services have been transferred to the customer, but payment is contingent upon a future event, other than the passage of time. As at March 31, 2021, Advent recognized contract
        assets of $0.7 million in the consolidated balance sheet. As at December 31, 2020, Advent recognized contract assets of $0.09 million in the consolidated balance sheet.</div>
      <div> <br>
      </div>
      <div style="text-align: justify;">Advent recognizes contract liabilities when we receive customer payments in advance of the performance obligations being satisfied on our contracts. As at March 31, 2021, Advent recognized contract liabilities of
        $0.04 million in the unaudited consolidated balance sheet. As at December 31, 2020, Advent recognized contract liabilities of $0.2 million in the consolidated balance sheet.</div>

      <div style="font-weight: bold; text-align: justify;">Critical Accounting Policies and Estimates</div>
      <div style="text-align: justify;"> <br>
      </div>
      <div style="text-align: justify;">Advent&#8217;s financial statements have been prepared in accordance with U.S. GAAP. The preparation of these financial statements requires Advent to make estimates and assumptions that affect the reported amounts of
        assets and liabilities and the disclosure of contingent assets and liabilities as of the balance sheet date, as well as the reported expenses incurred during the reporting period. Management bases its estimates on historical experience and on
        various other assumptions believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could differ from those estimates, and such differences could be
        material to Advent&#8217;s financial statements.</div>

      <div style="font-style: italic; font-weight: bold; text-align: justify;">Emerging Growth Company Status</div>
      <div style="text-align: justify;"> <br>
      </div>
      <div style="text-align: justify;">Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a
        Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can
        elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such an election to opt out is irrevocable. Advent elected not to opt out of such extended transition period
        which means that when a standard is issued or revised and it has different application dates for public or private companies, Advent, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new
        or revised standard, until such time Advent is no longer considered to be an emerging growth company. At times, Advent may elect to early adopt a new or revised standard. See Note 2 in the unaudited condensed consolidated financial statements
        included elsewhere in this Quarterly Report on Form 10-Q for more information about the recent accounting pronouncements adopted and the recent accounting pronouncements not yet adopted for the three months ending March 31, 2021 and 2020.</div>
      <div style="text-align: justify;"> <br>
      </div>
      <div style="text-align: justify;">In addition, Advent intends to rely on the other exemptions and reduced reporting requirements provided by the JOBS Act. Subject to certain conditions set forth in the JOBS Act, if, as an emerging growth company,
        Advent intends to rely on such exemptions, Advent is not required to, among other things: (a) provide an auditor&#8217;s attestation report on Advent&#8217;s system of internal control over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley
        Act; (b) provide all of the compensation disclosure that may be required of non-emerging growth public companies under the Dodd-Frank Wall Street Reform and Consumer Protection Act; (c) comply with any requirement that may be adopted by the Public
        Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor&#8217;s report providing additional information about the audit and the financial statements (auditor discussion and analysis); and (d) disclose
        certain executive compensation-related items such as the correlation between executive compensation and performance and comparisons of the Chief Executive Officer&#8217;s compensation to median employee compensation.</div>
      <div style="text-align: justify;"> <br>
      </div>
      <div style="text-align: justify;">Advent will remain an emerging growth company under the JOBS Act until the earliest of (a) the last day of Advent&#8217;s first fiscal year following the fifth anniversary of the closing of the Business Combination, (b)
        the last date of Advent&#8217;s fiscal year in which Advent has total annual gross revenue of at least $1.1 billion, (c) the date on which Advent is deemed to be a &#8220;large accelerated filer&#8221; under the rules of the SEC with at least $700.0 million of
        outstanding securities held by non-affiliates or (d) the date on which Advent has issued more than $1.0 billion in non-convertible debt securities during the previous three years.</div>
      <div style="text-align: justify;"> <br>
      </div>
      <div style="text-align: justify;">While Advent&#8217;s significant accounting policies are described in the notes to Advent&#8217;s financial statements (see Note 2 in the unaudited condensed consolidated financial statements), Advent believes that the following
        accounting policies require a greater degree of judgment and complexity. Accordingly, these are the policies Advent believes are the most critical to aid in fully understanding and evaluating Advent&#8217;s financial condition and results of operations.</div>
      <div style="font-style: italic; font-weight: bold; text-align: justify;"> <br>

      <div style="font-style: italic; font-weight: bold; text-align: justify;">Revenue Recognition from January 1, 2019</div>
      <div style="text-align: justify;"> <br>
      </div>
      <div style="text-align: justify;">In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), as amended, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the
        transfer of promised goods or services to customers. We adopted ASU No. 2014-09 on January 1, 2019, using the modified retrospective approach to all contracts not completed at the date of initial application. The prior period comparative
        information has not been restated and continues to be reported under the accounting guidance in effect for that period.</div>
      <div style="text-align: justify;"> <br>
      </div>
      <div style="text-align: justify;">In accordance with ASC 606, revenue is recognized when control of the promised goods or services are transferred to a customer in an amount that reflects the consideration that the Company expects to receive in
        exchange for those services. We apply the following five steps in order to determine the appropriate amount of revenue to be recognized as it fulfills its obligations under each of its arrangements:</div>

      </div>
      <div style="text-align: justify;">With significant and recurring customers, we negotiate written master agreements as framework agreements (general terms and conditions of trading), following individually purchase orders. For customers with no master
        agreements, the approved purchase orders form the contract. Effectively, contracts under the revenue standard have been assessed to be the purchase orders agreed with customers.</div>
      <div style="text-align: justify;"> <br>
      </div>
      <div style="text-align: justify;">We have assessed that each product sold is a single performance obligation because the promised goods are distinct on their own and within the context of contract. In cases where the agreement includes customization
        services for the contracted products, we are providing integrated services; therefore, the goods are not separately identifiable, but are inputs to produce and deliver a combined output and form a single performance obligation within the context of
        the contract. Furthermore, we assessed whether it acts as a principal or agent in each of its revenue arrangements and has concluded that in all sales transactions it acts as a principal. Additionally, we, taking into consideration the guidance and
        indicative factors provided by ASC 606, concluded that it provides assurance type warranties (warranty period is up to 45 days) as it does not provide a service to the customer beyond fixing defects that existed at the time of sale. We, based on
        historical performance, current circumstances, and projections of trends, estimated that no allowance for returns as per warranty policy should be recognized, at the time of sale, accounted for under ASC 460, Guarantees.</div>
      <div> <br>
      </div>
      <div style="text-align: justify;">Under ASC 606, we estimate the transaction price, including variable consideration, at the commencement of the contract and recognizes revenue over the contract term, rather than when fees become fixed or
        determinable. In other words, where contracts with customers include variable consideration (i.e. volume rebates), we estimate at contract inception the variable consideration and adjust the transaction price only to the extent that it is probable
        that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. Furthermore, no material rights or significant financing components
        have been identified in our contracts. Payment terms generally include advance payment requirements. The time between a customer&#8217;s payment and the receipt of funds is less than one year. Payment terms are in the majority fixed and do not include
        variable considerations, except from volume rebates.</div>
      <div> <br>
      </div>
      <div style="text-align: justify;">Revenue from satisfaction of performance obligations is recognized based on identified transaction price. The transaction price reflects the amount to which we have rights under the present contract. It is allocated
        to the distinct performance obligations based on standalone selling prices of the services promised in the contract. In cases of more than one performance obligation, we allocate transaction price to the distinct performance obligations in
        proportion to their observable stand-alone selling prices and recognizes revenue as those performance obligations are satisfied.</div>
      <div style="text-align: justify;"> <br>
      </div>
      <div style="text-align: justify;">In the majority of cases of product sales, revenue is recognized at a point in time when customer obtains control of the respective goods that is, when the products are shipped from our facilities as control passes
        to the customer in accordance with agreed contracts and the stated shipping terms. In cases where the contract includes customization services, which one performance obligation is identified, revenue is recognized over time as our performance does
        not create an asset with alternative use and we have an enforceable right to payment for performance completed to date. We use the input method (i.e. cost-to cost method) to measure progress towards complete satisfaction of the performance
        obligation.</div>

      <div style="text-align: justify;">Grants include cash subsidies received from various institutions and organizations. Grants are recognized as other income. Such amounts are recognized in the consolidated statements of operations when all conditions
        attached to the grants are fulfilled.</div>
      <div> <br>
      </div>
      <div style="text-align: justify;">Condition to the grants would not be fulfilled unless related costs have been characterized as eligible by the grantors, are actually incurred and there is certainty that costs are allowable. These grants are
        recognized as deferred income when received and recorded in income when the eligible and allowable related costs and expenses are incurred. Under all grant programs, a coordinator is specified. The coordinator, among other, receives the funding
        from the grantor and proceeds to its distribution to the parties agreed in the process specified in the program. We assessed whether it acts as a principal or agent in its role as a coordinator for specific grants and has concluded that in all
        related transactions it acts as an agent.</div>

      <div style="text-align: justify; color: rgb(0, 0, 0);">The Company allocates the fair value of purchase consideration transferred in a business acquisition to the tangible assets acquired, liabilities assumed, and intangible assets acquired based on
        their estimated fair values. The excess of the fair value of purchase consideration transferred over the fair values of these identifiable assets and liabilities is recorded as goodwill. Such valuations require management to make significant
        estimates and assumptions, especially with respect to intangible assets. Significant estimates in valuing certain intangible assets include, but are not limited to, future expected cash flows from acquired licenses, trade names, in process research
        and development ("R&amp;D"), useful lives and discount rates, patents, customer clientele, customer contracts and know-how. Management's estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently
        uncertain and unpredictable and, as a result, actual results may differ from estimates. During the measurement period, the Company may record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill.
        Upon the conclusion of the measurement period, any subsequent adjustments are recorded in the consolidated statement of operations.</div>

        <div style="text-align: justify; color: rgb(0, 0, 0);">For significant acquisitions, the Company obtains independent appraisals and valuations of the intangible (and certain tangible) assets acquired and certain assumed obligations as well as
          equity. The Company analyzes each acquisition individually and all acquisitions within each reporting period in aggregate to determine if those are material acquisitions in the context of ASC 805-10-50.</div>
        <div><br>
        </div>
        <div style="text-align: justify; color: rgb(0, 0, 0);">The estimated fair values and useful lives of identified intangible assets are based on many factors, including estimates and assumptions of future operating performance and cash flows of the
          acquired business, estimates of cost avoidance, the nature of the business acquired, the specific characteristics of the identified intangible assets and our historical experience and that of the acquired business. The estimates and assumptions
          used to determine the fair values and useful lives of identified intangible assets could change due to numerous factors, including product demand, market conditions, regulations affecting the business model of our operations, technological
          developments, economic conditions and competition.</div>
        <div><br>
        </div>
        <div style="text-align: justify; color: rgb(0, 0, 0);">We conduct a goodwill impairment analysis annually in the fourth fiscal quarter, as of October 1, and as necessary if changes in facts and circumstances indicate that the fair value of our
          reporting units may be less than their carrying amounts. When indicators of impairment do not exist and certain accounting criteria are met, we are able to evaluate goodwill impairment using a qualitative approach. When necessary, our
          quantitative goodwill impairment test consists of two steps. The first step requires that we compare the estimated fair value of our reporting units to the carrying value of the reporting unit&#8217;s net assets, including goodwill. If the fair value
          of the reporting unit is greater than the carrying value of its net assets, goodwill is not considered to be impaired and no further testing is required. If the fair value of the reporting unit is less than the carrying value of its net assets,
          we would be required to complete the second step of the test by analyzing the fair value of its goodwill. If the carrying value of the goodwill exceeds its fair value, an impairment charge is recorded. Currently, we identify one reporting unit.</div>

      <div> <br>
      </div>
      <div style="text-align: justify;">The Company follows the asset and liability method of accounting for income taxes under ASC 740, Income Taxes. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable
        to differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the
        years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that included the enactment date. Valuation
        allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized.</div>
      <div style="text-align: justify;"> <br>
      </div>
      <div style="text-align: justify;">ASC 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be
        recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. We are currently not aware of any issues under review that could result in significant accruals or material deviation from our position.
        We are subject to income tax examinations by major taxing authorities.</div>

      <div style="text-align: justify;">The Company may be subject to potential examination by U.S. federal, state and city, and the Subsidiary may be subject to potential examination by the Greek taxing authorities in the areas of income taxes. These
        potential examinations may include questioning the timing and amount of deductions, the nexus of income among various tax jurisdictions and compliance with the U.S. federal, state and city and Greek tax laws. On December 22, 2017, the Tax Cuts and
        Jobs Act of 2017 (&#8220;Tax Reform&#8221;) was signed into legislation. As part of the legislation, the U.S. corporate income tax rate was reduced from 35% to 21%, among other changes, for which our management does not believe that have a material effect on

        <div style="text-align: justify;">The Company accounts for the 26,392,355 warrants (comprising of 22,052,077 Public Warrants and 3,940,278 Private Placement Warrants) issued in connection with its Initial Public Offering and the 400,000 Working
          Capital Warrants issued at the consummation of the Business Combination in accordance with ASC 815-40-15-7D. If the warrants do not meet the criteria for equity treatment, they must be recorded as liabilities. We have determined that only the
          Private Placement Warrants and Working Capital Warrants must be recorded as liabilities and accordingly, the Company classifies these warrant instruments as liabilities at their fair value and adjusts the instruments to fair value at each
          reporting period. These liabilities are subject to re-measurement at each balance sheet date until exercised, and any change in fair value is recognized in the Company's statement of operations. The fair value of the Private Placement Warrants
          and the Working Capital Warrants has been determined using either the quoted price, if available, or was based on a modified Black-Scholes-Merton model. The fair value of the Private Placement Warrants and the Working Capital Warrants has been
          determined based on a modified Black-Scholes-Merton model for the quarter ended March 31, 2021.</div>

        any hedging transactions to mitigate the effect of foreign exchange due to the relatively low sums involved. As we increase in scale, we expect to continue to incur a substantial proportion of our costs in euros, and therefore expect to put in
        place appropriate foreign exchange risk mitigation features in due course.</div>

      </div>
      <div style="margin: 0px; text-align: justify;">In addition to providing measures prepared in accordance with GAAP, we present certain supplemental non-GAAP measures. These measures are EBITDA, Adjusted EBITDA and Adjusted Net Income / (Loss) , which
        we use to evaluate our operating performance, for business planning purposes and to measure our performance relative to that of our peers. These non-GAAP measures do not have any standardized meaning prescribed by GAAP and therefore may differ from
        to similar measures presented by other companies and may not be comparable to other similarly titled measures. We believe these measures are useful in evaluating the operating performance of the Company&#8217;s ongoing business. These measures should be
        considered in addition to, and not as a substitute for net income, operating expense and income, cash flows and other measures of financial performance and liquidity reported in accordance with GAAP. The calculation of these non-GAAP measures has
        been made on a consistent basis for all periods presented.</div>

        overall basis. We also believe EBITDA and Adjusted EBITDA are frequently used by securities analysts and investors when comparing our results with those of other companies. EBITDA differs from the most comparable GAAP measure, net income / (loss),
        primarily because it does not include income taxes, depreciation of property, plant and equipment, and amortization of intangible assets. Adjusted EBITDA adjusts EBITDA for transactional gains and losses, asset impairment charges, finance and other
        income<font style="color: rgb(0, 0, 0);">&#160;</font>and acquisition costs.</div>

        adjusting our results from continuing operations for changes in warrant liability and one-time transaction costs. Adjusted Net Loss differs from the most comparable GAAP measure, net income / (loss), primarily because it does not include one-time
        transaction costs and warrant liability changes. The following table shows a reconciliation of net income/(loss) for the three months ended March 31, 2021 and 2020.</div>

      </div>
      <div style="text-align: justify;">Our management, with the participation of our President and Chief Executive Officer and our Chief Financial Officer (our principal executive officer and principal financial and accounting officer, respectively),
        evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2021. The term &#8220;disclosure controls and procedures,&#8221; as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a
        company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC&#8217;s
        rules and forms.</div>

      </div>
      <div style="text-align: justify;">Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the
        Exchange Act is accumulated and communicated to the Company&#8217;s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure.</div>
      <div><br>
      </div>
      <div style="text-align: justify;">Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in
        evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of March 31, 2021, and as a result of the material weakness described below, our President and Chief
        Executive Officer and our Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were not effective at the reasonable assurance level as of the end of the period covered by this Report. Notwithstanding the
        identified material weakness, our management has concluded that the condensed consolidated financial statements included in this Quarterly Report on Form 10-Q present fairly, in all material respects, the Company&#8217;s financial position, results of
        operations and cash flows for the periods disclosed in accordance with U.S. GAAP.</div>

      <div style="text-align: justify; font-style: italic;">Remediation Efforts to Address the Previously Disclosed Material Weakness</div>
      <div><br>
      </div>
      <div style="text-align: justify;">As previously disclosed in Part I, Item 9A of our 2020 Annual Report, our management, concluded that our disclosure controls and procedures and internal controls over financial reporting were not effective as of
        December 31, 2020 and December 31, 2019 due to a material weakness. The material weakness related to not having adequate controls over accounting for complex accounting instruments and, in particular, related to errors in the accounting for
        warrants issued in connection with AMCI's Initial Public Offering and recorded in its pre-Business Combination, historical consolidated financial statements through December 31, 2020. In response to this material weakness, we have and will continue
        to implement a number of actions, as described below. Our management is committed to ensuring that our internal controls over financial reporting are designed and operating effectively. As previously disclosed, our remediation plan includes, but is
        not limited to, that we will improve the process and controls in the determination of the appropriate accounting and classification of our financial instruments and key agreements. When fully implemented and operational, we believe the controls we
        have designed or plan to design will remediate the control deficiency that have led to the material weakness we have identified and strengthen our internal controls over financial reporting. The material weakness will not be considered remediated
        until the applicable controls operate for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively.</div>

      <div style="text-align: justify; font-style: italic;">Changes in Internal Control over Financial Reporting</div>
      <div><br>
      </div>
      <div style="text-align: justify;">During the fiscal quarter ended March 31, 2021, we completed the Business Combination and the internal controls of AMCI became our internal controls. We are engaged in the process of design and implementation of our
        internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) in a manner commensurate with the scale of our operations subsequent to the Business Combination, including the enhancement of
        our internal and external technical accounting resources.</div>

      <div style="text-align: justify;">We are from time to time subject to various claims, lawsuits and other legal and administrative proceedings arising in the ordinary course of business. Some of these claims, lawsuits and other proceedings may involve
        highly complex issues that are subject to substantial uncertainties, and could result in damages, fines, penalties, non-monetary sanctions or relief. However, we do not consider any such claims, lawsuits or proceedings that are currently pending,
        individually or in the aggregate, to be material to our business or likely to result in a material adverse effect on our future operating results, financial condition or cash flows.</div>

      <div style="text-align: justify;">On December 17, 2020, a purported shareholder class action complaint was filed by Dillon Frey against the Company in the Supreme Court of the State of New York, County of New York, alleging that the proposed Business
        Combination with Advent is both procedurally and substantively unfair and seeking to maintain the action as a class action and enjoin the Business Combination, among other things, without stating a specific amount of damages. The complaint does not
        provide detail as to how the proposed Business Combination is unfair, either procedurally or substantively, and we believe it has no merit. On February 10, 2021, a notice of dismissal of the complaint was filed in the Supreme Court of the State of
        New York, County of New York.</div>

Immediately prior to the closing of the Business Combination, all shares of outstanding preferred stock Series A and preferred stock Series Seed of Legacy Advent were automatically converted into shares of the Legacy Advent's common stock. Upon the consummation of the Business Combination, each share of Legacy Advent common stock issued and outstanding was canceled and converted into the right to receive the amount of shares as determined based on the merger consideration of $250 million minus the estimated consolidated indebtedness of Legacy Advent and its subsidiaries as of the consummation of the Business Combination, net of their estimated consolidated cash and cash equivalents (&amp;#8220;Closing Net Indebtedness&amp;#8221;) divided by $10.00. The Closing Net Indebtedness was based solely on estimates determined shortly prior to the closing and was not subject to any post-closing true-up or adjustment.&lt;/div&gt;&lt;div&gt;&amp;#160;&lt;/div&gt;&lt;div&gt;Upon the closing of the Business Combination, AMCI's certificate of incorporation was amended and restated to, among other things, authorize the issuance of 111,000,000 shares, of which 110,000,000 shares are shares of common stock, par value $0.0001 per share and 1,000,000 shares are shares of undesignated preferred stock, par value $0.0001 per share.&lt;/div&gt;&lt;div&gt;&amp;#160;&lt;/div&gt;&lt;div&gt;In connection with the execution of the Business Combination Agreement, AMCI entered into separate subscription agreements (each, a "Subscription Agreement") with a number of investors (each a "Subscriber"), pursuant to which the Subscribers agreed to purchase, and AMCI agreed to sell to the Subscribers, an aggregate of 6,500,000 shares of common stock (the "PIPE Shares"), for a purchase price of $10.00 per share and an aggregate purchase price of $65.0 million, in a private placement pursuant to the subscription agreements (the "PIPE"). The PIPE investment closed simultaneously with the consummation of the Business Combination.&lt;/div&gt;&lt;div&gt;&amp;#160;&lt;/div&gt;&lt;div&gt;The Business Combination is accounted for as a reverse recapitalization in accordance with GAAP. Under this method of accounting, AMCI was treated as the "acquired" company for financial reporting purposes. See Note 1 "Basis of Presentation" in the accompanying unaudited condensed consolidated financial statements for further details. Accordingly, for accounting purposes, the Business Combination was treated as the equivalent of Legacy Advent issuing stock for the net assets of AMCI, accompanied by a recapitalization.

The results of UltraCell&amp;#8217;s operations have been included in the unaudited condensed consolidated financial statements since the acquisition date.&lt;/div&gt;&lt;div&gt;&amp;#160;&lt;/div&gt;&lt;div style="text-align: justify; color: rgb(0, 0, 0);"&gt;UltraCell is an entity specialized in lightweight fuel cells for the portable power market with mature products and cutting-edge technology.&lt;/div&gt;&lt;div style="text-align: justify; color: rgb(0, 0, 0);"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;font style="color: rgb(0, 0, 0);"&gt;The acquisition consideration transferred totaled $6.0 million, of which $4.0 million was cash and $2 million was the fair value of the contingent consideration. The contingent consideration arrangement required the Company to pay $2 million of additional cash to UltraCell&amp;#8217;s former holders of membership interests, if UltraCell entered into certain customer arrangements for sales of products prior to June 30, 2021. &lt;/font&gt;On April 16, 2021 Advent paid the additional consideration based on UltraCell achieving completion of the terms of the contingent consideration.&lt;/div&gt;&lt;div&gt;&amp;#160;&lt;/div&gt;&lt;div style="text-align: justify; color: rgb(0, 0, 0);"&gt;The estimated fair values of the assets acquired and liabilities assumed at the acquisition date was $5.5 million, resulting in the recognition of provisional goodwill of $0.5 million. The Company is in the process of obtaining third-party valuations of certain intangible assets; thus, the provisional measurements of intangible assets and goodwill are subject to change.&lt;/div&gt;&lt;div style="text-align: justify; color: rgb(0, 0, 0);"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: justify; color: rgb(0, 0, 0);"&gt;The provisional value of $5 million of intangibles relates to trademarks, patents, customer relationships, customer contracts and know-how. Those intangibles mainly relate to definite-live intangible assets with estimated useful lives that vary between 3-10 years, with the exception of contract backlogs which are amortized over the remaining period of the contracts assumed based on income approach. During the period from acquisition and up to March 31, 2021, the Company has recognized in the condensed consolidated statement of operations amortization for those intangibles of $0.2 million.&lt;br /&gt;&lt;/div&gt;&lt;/div&gt;</us-gaap:BusinessCombinationDisclosureTextBlock>

The excess of the fair value of purchase consideration transferred over the fair values of these identifiable assets and liabilities is recorded as goodwill. In case the fair value of purchase consideration transferred is below fair values of these identifiable assets and liabilities, the Company recognizes a gain from a bargain purchase. Such valuations require management to make significant estimates and assumptions, especially with respect to intangible assets. Significant estimates in valuing certain intangible assets include, but are not limited to, future expected cash flows from acquired licenses, trade names, in process research and development ("R&amp;amp;D"), useful lives and discount rates, patents, customer clientele, customer contracts and know-how. Management's estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. During the measurement period, the Company may record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period, any subsequent adjustments are recorded in the consolidated statement of operations.&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: justify; color: rgb(0, 0, 0);"&gt;For significant acquisitions, the Company obtains independent appraisals and valuations of the intangible (and certain tangible) assets acquired and certain assumed obligations. The Company analyzes each acquisition individually and all acquisitions within each reporting period in aggregate to determine if those are material acquisitions in the context of ASC 805-10-50.&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: justify; color: rgb(0, 0, 0);"&gt;The estimated fair values and useful lives of identified intangible assets are based on many factors, including estimates and assumptions of future operating performance and cash flows of the acquired business, estimates of cost avoidance, the nature of the business acquired, the specific characteristics of the identified intangible assets and our historical experience and that of the acquired business. The estimates and assumptions used to determine the fair values and useful lives of identified intangible assets could change due to numerous factors, including product demand, market conditions, regulations affecting the business model of our operations, technological developments, economic conditions and competition.&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: justify; color: rgb(0, 0, 0);"&gt;We conduct a goodwill impairment analysis annually in the fourth fiscal quarter, as of October 1, and as necessary if changes in facts and circumstances indicate that the fair value of our reporting units may be less than their carrying amounts. When indicators of impairment do not exist and certain accounting criteria are met, we are able to evaluate goodwill impairment using a qualitative approach. When necessary, our quantitative goodwill impairment test consists of two steps. The first step requires that we compare the estimated fair value of our reporting units to the carrying value of the reporting unit&amp;#8217;s net assets, including goodwill. If the fair value of the reporting unit is greater than the carrying value of its net assets, goodwill is not considered to be impaired and no further testing is required. If the fair value of the reporting unit is less than the carrying value of its net assets, we would be required to complete the second step of the test by analyzing the fair value of its goodwill. If the carrying value of the goodwill exceeds its fair value, an impairment charge is recorded. Currently, we identify one reporting unit.&lt;/div&gt;&lt;/div&gt;</us-gaap:GoodwillAndIntangibleAssetsIntangibleAssetsPolicy>

In July 2018, ASU 2018-10, Codification Improvements to Topic 842, Leases, was issued to provide more detailed guidance and additional clarification for implementing ASU 2016-02. Furthermore, in July 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvements, which provides an optional transition method in addition to the existing modified retrospective transition method by allowing a cumulative effect adjustment to the opening balance of retained earnings in the period of adoption. Additionally, ASU 2019-01, Codification Improvements to Topic 842, Leases and ASU 2020-02, Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 119 and Update to SEC Section on Effective Date Related to Accounting Standards Update No. 2016-02, Leases (Topic 842), provided additional clarifications for implementing ASU 2016.02.&amp;#160; The new lease standard was originally effective for the private entities on January 1, 2021, with early adoption permitted. Following the issuance of ASU 2020-05, Effective Dates for Certain Entities (Topic 842), the effective date of Leases was deferred for private entities (the &amp;#8220;all other&amp;#8221; category) to fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. Early application continues to be permitted which means that an entity may choose to implement Leases before those deferred effective dates. The Company is currently evaluating the effect of the adoption of this guidance on the consolidated financial statements.&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: justify; color: rgb(0, 0, 0);"&gt;In June 2016, the FASB issued ASU 2016-13, Financial Instruments&amp;#8212;Credit Losses (Topic 326): Measurement of Credit Losses of Financial Instruments, which, amends the requirement on the measurement and recognition of expected credit losses for financial assets held. Furthermore, amendments, ASU 2019-10 and ASU 2019-11 provided additional clarification for implementing ASU 2016-13. ASU 2016-13 is effective for the Company beginning January 1, 2023, with early adoption permitted.

As an emerging growth company (&amp;#8220;EGC&amp;#8221;), the JOBS Act allows the Company to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are applicable to private companies. The Company elected to use this extended transition period under the JOBS Act until such time the Company is no longer considered to be an EGC. The Company applied the following new accounting policies:&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;table cellpadding="0" cellspacing="0" class="DSPFListTable" style="width: 100%; font-family: 'Times New Roman'; font-size: 10pt;"&gt;&lt;tr style="vertical-align: top;"&gt;&lt;td style="vertical-align: top; width: 18pt;"&gt;&lt;div style="color: rgb(0, 0, 0); font-style: italic; font-weight: bold;"&gt;(a)&lt;/div&gt;&lt;/td&gt;&lt;td style="align: left; vertical-align: top; width: auto;"&gt;&lt;div style="color: rgb(0, 0, 0); font-style: italic; font-weight: bold;"&gt;Business acquisitions, Goodwill and Intangible Assets&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: justify; color: rgb(0, 0, 0);"&gt;The Company allocates the fair value of purchase consideration transferred in a business acquisition to the tangible assets acquired, liabilities assumed, and intangible assets acquired based on their estimated fair values. The excess of the fair value of purchase consideration transferred over the fair values of these identifiable assets and liabilities is recorded as goodwill. In case the fair value of purchase consideration transferred is below fair values of these identifiable assets and liabilities, the Company recognizes a gain from a bargain purchase. Such valuations require management to make significant estimates and assumptions, especially with respect to intangible assets. Significant estimates in valuing certain intangible assets include, but are not limited to, future expected cash flows from acquired licenses, trade names, in process research and development ("R&amp;amp;D"), useful lives and discount rates, patents, customer clientele, customer contracts and know-how. Management's estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. During the measurement period, the Company may record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period, any subsequent adjustments are recorded in the consolidated statement of operations.&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: justify; color: rgb(0, 0, 0);"&gt;For significant acquisitions, the Company obtains independent appraisals and valuations of the intangible (and certain tangible) assets acquired and certain assumed obligations. The Company analyzes each acquisition individually and all acquisitions within each reporting period in aggregate to determine if those are material acquisitions in the context of ASC 805-10-50.&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: justify; color: rgb(0, 0, 0);"&gt;The estimated fair values and useful lives of identified intangible assets are based on many factors, including estimates and assumptions of future operating performance and cash flows of the acquired business, estimates of cost avoidance, the nature of the business acquired, the specific characteristics of the identified intangible assets and our historical experience and that of the acquired business. The estimates and assumptions used to determine the fair values and useful lives of identified intangible assets could change due to numerous factors, including product demand, market conditions, regulations affecting the business model of our operations, technological developments, economic conditions and competition.&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: justify; color: rgb(0, 0, 0);"&gt;We conduct a goodwill impairment analysis annually in the fourth fiscal quarter, as of October 1, and as necessary if changes in facts and circumstances indicate that the fair value of our reporting units may be less than their carrying amounts. When indicators of impairment do not exist and certain accounting criteria are met, we are able to evaluate goodwill impairment using a qualitative approach. When necessary, our quantitative goodwill impairment test consists of two steps. The first step requires that we compare the estimated fair value of our reporting units to the carrying value of the reporting unit&amp;#8217;s net assets, including goodwill. If the fair value of the reporting unit is greater than the carrying value of its net assets, goodwill is not considered to be impaired and no further testing is required. If the fair value of the reporting unit is less than the carrying value of its net assets, we would be required to complete the second step of the test by analyzing the fair value of its goodwill. If the carrying value of the goodwill exceeds its fair value, an impairment charge is recorded. Currently, we identify one reporting unit.&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;table cellpadding="0" cellspacing="0" class="DSPFListTable" style="font-family: 'Times New Roman'; font-size: 10pt; width: 100%; text-align: left; color: #000000;"&gt;&lt;tr&gt;&lt;td style="width: 18pt; vertical-align: top; color: rgb(0, 0, 0); font-style: italic; font-weight: bold;"&gt;(b)&lt;/td&gt;&lt;td style="width: auto; vertical-align: top; text-align: justify;"&gt;&lt;div style="color: rgb(0, 0, 0); font-style: italic; font-weight: bold;"&gt;Warrants&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: justify; color: rgb(0, 0, 0);"&gt;The Company may issue or assume common stock warrants with debt, equity or as a standalone financing instruments that are recorded as either liabilities or equity in accordance with the respective accounting guidance.

Each Public Warrant entitles the registered holder to purchase one share of Common Stock at a price of $11.50 per share, subject to adjustment, at any time commencing 30 days after the completion of the Business Combination. The Public Warrants will expire five years after the completion of a Business Combination or earlier upon redemption or liquidation.&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="color: rgb(0, 0, 0);"&gt;Once the warrants become exercisable, the Company may redeem the Public Warrants:&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="color: rgb(0, 0, 0);"&gt;&amp;#8211;in whole and not in part;&lt;/div&gt;&lt;div style="color: rgb(0, 0, 0);"&gt;&amp;#8211;at a price of $0.01 per warrant;&lt;/div&gt;&lt;div style="color: rgb(0, 0, 0);"&gt;&amp;#8211;upon not less than 30 days&amp;#8217; prior written notice of redemption;&lt;/div&gt;&lt;div style="color: rgb(0, 0, 0);"&gt;&amp;#8211;if, and only if, the reported last sale price of the Company&amp;#8217;s common stock equals or exceeds $18.00 per share for any 20 trading days within a 30-trading day period ending three business days before the Company sends the notice of redemption to the warrant holders; and&lt;/div&gt;&lt;div style="color: rgb(0, 0, 0);"&gt;&amp;#8211;if, and only if, there is a current registration statement in effect with respect to the shares of common stock underlying such warrants.&lt;/div&gt;&lt;div&gt;&amp;#160;&lt;/div&gt;&lt;div style="color: rgb(0, 0, 0);"&gt;If the Company calls the Public Warrants for redemption, management will have the option to require all holders that wish to exercise the Public Warrants to do so on a &amp;#8220;cashless basis,&amp;#8221; as described in the warrant agreement. The exercise price and number of shares of common stock issuable upon exercise of the warrants may be adjusted in certain circumstances including in the event of a stock dividend, or recapitalization, reorganization, merger or consolidation. However, the warrants will not be adjusted for issuance of common stock at a price below its exercise price. In addition, the warrant agreement provides that in case of a tender offer or exchange that involves 50% or more of the Company&amp;#8217;s stockholders, the Public Warrants may be settled in cash, equity securities or other assets depending on the kind and amount received per share by the holders of the common stock in such consolidation or merger that affirmatively make such election.&lt;/div&gt;&lt;div&gt;&amp;#160;&lt;/div&gt;&lt;div style="color: rgb(0, 0, 0);"&gt;Public Warrants are classified in equity in accordance with the Company&amp;#8217;s evaluation of the provisions of ASC 480 and ASC 815. The Company analyzed the terms of the Public Warrants and concluded that there are no terms that provide that the warrant is not indexed to the issuer&amp;#8217;s common stock. The Company also analyzed the tender offer provision discussed above, and considering that upon the Closing of the Business Combination the Company has a single class of common shares, concluded that the exception discussed in ASC 815-40-25 applies, and thus equity classification is not precluded.&lt;/div&gt;&lt;/div&gt;</us-gaap:StockholdersEquityNoteDisclosureTextBlock>

In addition, upon the closing of the Business Combination, the working capital loan provided by AMCI&amp;#8217;s Sponsor to AMCI was converted into 400,000 Working Capital Warrants, which were also assumed. The terms of the Working Capital Warrants are the same as those of the Private Placement Warrants.&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: justify; color: rgb(0, 0, 0);"&gt;As of March 31, 2021, the Company had 4,340,278 Private Placement Warrants and Working Capital Warrants outstanding. Each Private Placement Warrant and Working Capital Warrant entitles the registered holder to purchase one share of Common Stock at a price of $11.50 per share, subject to adjustment, at any time commencing 30 days after the completion of the Business Combination. The Public Warrants will expire five years after the completion of a Business Combination or earlier upon redemption or liquidation.&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: justify; color: rgb(0, 0, 0);"&gt;The Private Placement Warrants and Working Capital Warrants are identical to the Public Warrants, except that the Private Placement Warrants and Working Capital Warrants and the common stock issuable upon the exercise of those warrants will not be transferable, assignable or salable until 30 days after the completion of a Business Combination, subject to certain limited exceptions. Additionally, the Private Placement Warrants and Working Capital Warrants will be exercisable on a cashless basis and be non-redeemable so long as they are held by the initial purchasers or their permitted transferees. If those warrants are held by someone other than the initial purchasers or their permitted transferees, they will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants. As of March 31, 2021, Private Placement Warrants and Working Capital Warrants are held by its initial purchasers.&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="color: rgb(0, 0, 0);"&gt;According to the provisions of the Private Placement Warrants and Working Capital Warrants warrant agreements, the exercise price and number of shares of common stock issuable upon exercise of those warrants may be adjusted in certain circumstances including in the event of a stock dividend, or recapitalization, reorganization, merger or consolidation. Private Placement Warrants and Working Capital Warrants are classified as liabilities in accordance with the Company&amp;#8217;s evaluation of the provisions of ASC 815- 40-15, which provides that a warrant is not indexed to the issuer&amp;#8217;s common stock if the terms of the warrant require an adjustment to the exercise price upon a specified event and that event is not an input to the fair value of the warrant with a fixed exercise price and fixed number of underlying shares.&lt;/div&gt;&lt;/div&gt;</adn:PrivatePlacementWarrantsAndWorkingCapitalWarrantsTextBlock>

(&#8220;AMCI&#8221;), consummated the previously announced business combination (the &#8220;Business Combination&#8221;) pursuant to that certain merger agreement (the &#8220;Agreement and Plan of Merger&#8221;), dated October 12, 2020, by and among AMCI, AMCI Merger Sub Corp., a Delaware corporation and newly formed wholly-owned subsidiary of AMCI (&#8220;Merger Sub&#8221;), AMCI Sponsor LLC (the &#8220;Sponsor&#8221;), solely in the capacity as the representative from and after the effective time of the Business Combination for the stockholders of AMCI (the &#8220;Purchaser Representative&#8221;), Advent Technologies, Inc., a Delaware corporation (&#8220;Legacy Advent&#8221;), and Vasillios Gregoriou, solely in his capacity as the representative from and after the effective time for the Legacy Advent stockholders (the &#8220;Seller Representative&#8221;), as amended by Amendment No. 1 and Amendment No. 2 to the Agreement and Plan of Merger, dated as of October 19, 2020 and December 31, 2020, respectively, by and among AMCI, Merger Sub, Sponsor, Legacy Advent, and Seller Representative. In connection with the closing of the Business Combination (the &#8220;Closing&#8221;), AMCI acquired 100% of the stock of Legacy Advent (as it existed immediately prior to the Closing) and its subsidiaries.</div><div>&#160;</div><div style="text-align: justify; color: rgb(0, 0, 0);">On the Closing Date, and in connection with the closing of the Business Combination, AMCI changed its name to Advent Technologies Holding, Inc. (the "Company" or "Advent"). Legacy Advent was deemed the accounting acquirer in the Business Combination based on an analysis of the criteria outlined in Accounting Standards Codification ("ASC") 805. This determination was primarily based on Legacy Advent's stockholders prior to the Business Combination having a majority of the voting interests in the combined company, Legacy Advent's operations comprising the ongoing operations of the combined company, Legacy Advent's board of directors comprising a majority of the board of directors of the combined company, and Legacy Advent's senior management comprising the senior management of the combined company. Accordingly, for accounting purposes, the Business Combination was treated as the equivalent of Legacy Advent issuing stock for the net assets of AMCI, accompanied by a recapitalization. The net assets of AMCI are stated at historical cost, with no goodwill or other intangible assets recorded.</div><div>&#160;</div><div style="text-align: justify; color: rgb(0, 0, 0);">While AMCI was the legal acquirer in the Business Combination, because Legacy Advent was deemed the accounting acquirer, the historical financial statements of Legacy Advent became the historical financial statements of the combined company, upon the consummation of the Business Combination. As a result, the unaudited condensed consolidated financial statements included in this report reflect (i) the historical operating results of Legacy Advent prior to the Business Combination; (ii) the results of the Company (combined results of AMCI and Legacy Advent) following the closing of the Business Combination; (iii) the assets and liabilities of Legacy Advent at their historical cost; and (iv) Company&#8217;s equity structure for all periods presented.</div><div>&#160;</div><div style="text-align: justify; color: rgb(0, 0, 0);">In accordance with guidance applicable to these circumstances, the equity structure has been restated in all comparative periods up to the Closing Date, to reflect the number of shares of the Company's common stock, $0.0001 par value per share ("Common Stock") issued to Legacy Advent's stockholders in connection with the recapitalization transaction. As such, the shares and corresponding capital amounts and earnings per share related to Legacy Advent Preferred Stock (&#8220;Preferred Series A&#8221; and &#8220;Preferred Series Seed&#8221;) and Legacy Advent common stock prior to the Business Combination have been retroactively restated as shares reflecting the exchange ratio established in the Business Combination Agreement. Activity within the statement of changes in stockholders' equity / (deficit) for the issuances of Legacy Advent's Preferred Stock, were also retroactively converted to Legacy Advent common stock. (Note 3)</div><div>&#160;</div><div style="text-align: justify;"><font style="color: rgb(0, 0, 0);">On February 18, 2021, the Company, entered into a Membership Interest Purchase Agreement with Bren-Tronics, Inc.

The unaudited financial information reflects, in the opinion of management, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair statement of the Company's financial position, results of operations and cash flows for the periods indicated. The results reported for the interim period presented are not necessarily indicative of results that may be expected for the full year. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company's audited consolidated financial statements as of and for the year ended December 31, 2020 included in the Current Report on Form 8-K filed with the SEC on February 9, 2021 (the &#8220;Original Form 8-K&#8221;), as amended by Amendment No. 1 to Form 8-K, filed with the SEC on February 9, 2021 (&#8220;Amendment No. 1&#8221;), as further amended by Amendment No. 2 to Form 8-K, filed with the SEC on March 26, 2021 (&#8220;Amendment No. 2&#8221;) and as further amended by Amendment No 3 to Form 8-K, filed with the SEC on May 20, 2021 (&#8220;Amendment No. 3,&#8221; and, the Original Form 8-K, as so amended by Amendment No. 1, Amendment No. 2 and Amendment No. 3, the &#8220;Super Form 8-K&#8221;).</div><div>&#160;</div><div style="text-align: justify; color: rgb(0, 0, 0);">The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries.

Accordingly, these financial statements do not include any adjustments that may result in the event the Company is unable to continue as a going concern.</div><div>&#160;</div><div style="text-align: justify; color: rgb(0, 0, 0);">Beginning in March 2020, the COVID-19 pandemic and the measures imposed to contain this pandemic have disrupted and are expected to continue to impact the Company&#8217;s business. The magnitude of the impact of the COVID-19 pandemic on the Company&#8217;s productivity, results of operations and financial position, and its disruption to the Company&#8217;s business (fuel cells sales timeline, realization of income from grants received) will depend in part, on the length and severity of these restrictions and on the Company&#8217;s ability to conduct business in the ordinary course.</div><div>&#160;</div><div style="text-align: justify; color: rgb(0, 0, 0);">As of the date of this Quarterly Report on Form 10-Q, the Company&#8217;s existing cash resources are sufficient to support planned operations for the next 12 months. As a result, management believes that the Company's existing financial resources are sufficient to continue operating activities for at least one year past the issuance date of the unaudited condensed consolidated financial statements.</div></div><span></span>

As an emerging growth company (&#8220;EGC&#8221;), the JOBS Act allows the Company to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are applicable to private companies. The Company elected to use this extended transition period under the JOBS Act until such time the Company is no longer considered to be an EGC. The Company applied the following new accounting policies:</div><div><br /></div><table cellpadding="0" cellspacing="0" class="DSPFListTable" style="width: 100%; font-family: 'Times New Roman'; font-size: 10pt;"><tr style="vertical-align: top;"><td style="vertical-align: top; width: 18pt;"><div style="color: rgb(0, 0, 0); font-style: italic; font-weight: bold;">(a)</div></td><td style="align: left; vertical-align: top; width: auto;"><div style="color: rgb(0, 0, 0); font-style: italic; font-weight: bold;">Business acquisitions, Goodwill and Intangible Assets</div></td></tr></table><div><br /></div><div style="text-align: justify; color: rgb(0, 0, 0);">The Company allocates the fair value of purchase consideration transferred in a business acquisition to the tangible assets acquired, liabilities assumed, and intangible assets acquired based on their estimated fair values. The excess of the fair value of purchase consideration transferred over the fair values of these identifiable assets and liabilities is recorded as goodwill. In case the fair value of purchase consideration transferred is below fair values of these identifiable assets and liabilities, the Company recognizes a gain from a bargain purchase. Such valuations require management to make significant estimates and assumptions, especially with respect to intangible assets. Significant estimates in valuing certain intangible assets include, but are not limited to, future expected cash flows from acquired licenses, trade names, in process research and development ("R&amp;D"), useful lives and discount rates, patents, customer clientele, customer contracts and know-how. Management's estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. During the measurement period, the Company may record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period, any subsequent adjustments are recorded in the consolidated statement of operations.</div><div><br /></div><div style="text-align: justify; color: rgb(0, 0, 0);">For significant acquisitions, the Company obtains independent appraisals and valuations of the intangible (and certain tangible) assets acquired and certain assumed obligations. The Company analyzes each acquisition individually and all acquisitions within each reporting period in aggregate to determine if those are material acquisitions in the context of ASC 805-10-50.</div><div><br /></div><div style="text-align: justify; color: rgb(0, 0, 0);">The estimated fair values and useful lives of identified intangible assets are based on many factors, including estimates and assumptions of future operating performance and cash flows of the acquired business, estimates of cost avoidance, the nature of the business acquired, the specific characteristics of the identified intangible assets and our historical experience and that of the acquired business. The estimates and assumptions used to determine the fair values and useful lives of identified intangible assets could change due to numerous factors, including product demand, market conditions, regulations affecting the business model of our operations, technological developments, economic conditions and competition.</div><div><br /></div><div style="text-align: justify; color: rgb(0, 0, 0);">We conduct a goodwill impairment analysis annually in the fourth fiscal quarter, as of October 1, and as necessary if changes in facts and circumstances indicate that the fair value of our reporting units may be less than their carrying amounts. When indicators of impairment do not exist and certain accounting criteria are met, we are able to evaluate goodwill impairment using a qualitative approach. When necessary, our quantitative goodwill impairment test consists of two steps. The first step requires that we compare the estimated fair value of our reporting units to the carrying value of the reporting unit&#8217;s net assets, including goodwill. If the fair value of the reporting unit is greater than the carrying value of its net assets, goodwill is not considered to be impaired and no further testing is required. If the fair value of the reporting unit is less than the carrying value of its net assets, we would be required to complete the second step of the test by analyzing the fair value of its goodwill. If the carrying value of the goodwill exceeds its fair value, an impairment charge is recorded. Currently, we identify one reporting unit.</div><div><br /></div><table cellpadding="0" cellspacing="0" class="DSPFListTable" style="font-family: 'Times New Roman'; font-size: 10pt; width: 100%; text-align: left; color: #000000;"><tr><td style="width: 18pt; vertical-align: top; color: rgb(0, 0, 0); font-style: italic; font-weight: bold;">(b)</td><td style="width: auto; vertical-align: top; text-align: justify;"><div style="color: rgb(0, 0, 0); font-style: italic; font-weight: bold;">Warrants</div></td></tr></table><div><br /></div><div style="text-align: justify; color: rgb(0, 0, 0);">The Company may issue or assume common stock warrants with debt, equity or as a standalone financing instruments that are recorded as either liabilities or equity in accordance with the respective accounting guidance.

The Private Placement Warrants and the Working Capital Warrants have substantially the same terms as the 22,052,077 warrants, each exercisable to purchase one share of common stock at an exercise price of $11.50 per share, issued by AMCI in its Initial Public Offering (the &#8220;Public Warrants&#8221;). The Warrant Liability was remeasured to its fair value at each reporting period and upon settlement.

In July 2018, ASU 2018-10, Codification Improvements to Topic 842, Leases, was issued to provide more detailed guidance and additional clarification for implementing ASU 2016-02. Furthermore, in July 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvements, which provides an optional transition method in addition to the existing modified retrospective transition method by allowing a cumulative effect adjustment to the opening balance of retained earnings in the period of adoption. Additionally, ASU 2019-01, Codification Improvements to Topic 842, Leases and ASU 2020-02, Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 119 and Update to SEC Section on Effective Date Related to Accounting Standards Update No. 2016-02, Leases (Topic 842), provided additional clarifications for implementing ASU 2016.02.&#160; The new lease standard was originally effective for the private entities on January 1, 2021, with early adoption permitted. Following the issuance of ASU 2020-05, Effective Dates for Certain Entities (Topic 842), the effective date of Leases was deferred for private entities (the &#8220;all other&#8221; category) to fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. Early application continues to be permitted which means that an entity may choose to implement Leases before those deferred effective dates.

Furthermore, amendments, ASU 2019-10 and ASU 2019-11 provided additional clarification for implementing ASU 2016-13.

The Closing Net Indebtedness was based solely on estimates determined shortly prior to the closing and was not subject to any post-closing true-up or adjustment.</div><div>&#160;</div><div>Upon the closing of the Business Combination, AMCI's certificate of incorporation was amended and restated to, among other things, authorize the issuance of 111,000,000 shares, of which 110,000,000 shares are shares of common stock, par value $0.0001 per share and 1,000,000 shares are shares of undesignated preferred stock, par value $0.0001 per share.</div><div>&#160;</div><div>In connection with the execution of the Business Combination Agreement, AMCI entered into separate subscription agreements (each, a "Subscription Agreement") with a number of investors (each a "Subscriber"), pursuant to which the Subscribers agreed to purchase, and AMCI agreed to sell to the Subscribers, an aggregate of 6,500,000 shares of common stock (the "PIPE Shares"), for a purchase price of $10.00 per share and an aggregate purchase price of $65.0 million, in a private placement pursuant to the subscription agreements (the "PIPE"). The PIPE investment closed simultaneously with the consummation of the Business Combination.</div><div>&#160;</div><div>The Business Combination is accounted for as a reverse recapitalization in accordance with GAAP. Under this method of accounting, AMCI was treated as the "acquired" company for financial reporting purposes. See Note 1 "Basis of Presentation" in the accompanying unaudited condensed consolidated financial statements for further details. Accordingly, for accounting purposes, the Business Combination was treated as the equivalent of Legacy Advent issuing stock for the net assets of AMCI, accompanied by a recapitalization. The net assets of AMCI are stated at historical cost, with no goodwill or other intangible assets recorded.</div><div>&#160;</div><div style="text-align: justify; color: rgb(0, 0, 0);">The following table reconciles the elements of the Business Combination to the consolidated statement of cash flows and the consolidated statement of changes in equity for the three month ended March 31, 2021:<br /><br /></div><table align="center" border="0" cellpadding="0" cellspacing="0" style="width: 90%;

Each Public Warrant entitles the registered holder to purchase one share of Common Stock at a price of $11.50 per share, subject to adjustment, at any time commencing 30 days after the completion of the Business Combination. The Public Warrants will expire five years after the completion of a Business Combination or earlier upon redemption or liquidation.</div><div><br /></div><div style="color: rgb(0, 0, 0);">Once the warrants become exercisable, the Company may redeem the Public Warrants:</div><div><br /></div><div style="color: rgb(0, 0, 0);">&#8211;in whole and not in part;</div><div style="color: rgb(0, 0, 0);">&#8211;at a price of $0.01 per warrant;</div><div style="color: rgb(0, 0, 0);">&#8211;upon not less than 30 days&#8217; prior written notice of redemption;</div><div style="color: rgb(0, 0, 0);">&#8211;if, and only if, the reported last sale price of the Company&#8217;s common stock equals or exceeds $18.00 per share for any 20 trading days within a 30-trading day period ending three business days before the Company sends the notice of redemption to the warrant holders; and</div><div style="color: rgb(0, 0, 0);">&#8211;if, and only if, there is a current registration statement in effect with respect to the shares of common stock underlying such warrants.</div><div>&#160;</div><div style="color: rgb(0, 0, 0);">If the Company calls the Public Warrants for redemption, management will have the option to require all holders that wish to exercise the Public Warrants to do so on a &#8220;cashless basis,&#8221; as described in the warrant agreement. The exercise price and number of shares of common stock issuable upon exercise of the warrants may be adjusted in certain circumstances including in the event of a stock dividend, or recapitalization, reorganization, merger or consolidation. However, the warrants will not be adjusted for issuance of common stock at a price below its exercise price. In addition, the warrant agreement provides that in case of a tender offer or exchange that involves 50% or more of the Company&#8217;s stockholders, the Public Warrants may be settled in cash, equity securities or other assets depending on the kind and amount received per share by the holders of the common stock in such consolidation or merger that affirmatively make such election.</div><div>&#160;</div><div style="color: rgb(0, 0, 0);">Public Warrants are classified in equity in accordance with the Company&#8217;s evaluation of the provisions of ASC 480 and ASC 815. The Company analyzed the terms of the Public Warrants and concluded that there are no terms that provide that the warrant is not indexed to the issuer&#8217;s common stock. The Company also analyzed the tender offer provision discussed above, and considering that upon the Closing of the Business Combination the Company has a single class of common shares, concluded that the exception discussed in ASC 815-40-25 applies, and thus equity classification is not precluded.</div></div><span></span>

(&#8220;AMCI&#8221;), consummated the previously announced business combination (the &#8220;Business Combination&#8221;) pursuant to that certain merger agreement (the &#8220;Agreement and Plan of Merger&#8221;), dated October 12, 2020, by and among AMCI, AMCI Merger Sub Corp., a Delaware corporation and newly formed wholly-owned subsidiary of AMCI (&#8220;Merger Sub&#8221;), AMCI Sponsor LLC (the &#8220;Sponsor&#8221;), solely in the capacity as the representative from and after the effective time of the Business Combination for the stockholders of AMCI (the &#8220;Purchaser Representative&#8221;), Advent Technologies, Inc., a Delaware corporation (&#8220;Legacy Advent&#8221;), and Vasillios Gregoriou, solely in his capacity as the representative from and after the effective time for the Legacy Advent stockholders (the &#8220;Seller Representative&#8221;), as amended by Amendment No. 1 and Amendment No. 2 to the Agreement and Plan of Merger, dated as of October 19, 2020 and December 31, 2020, respectively, by and among AMCI, Merger Sub, Sponsor, Legacy Advent, and Seller Representative. In connection with the closing of the Business Combination (the &#8220;Closing&#8221;), AMCI acquired 100% of the stock of Legacy Advent (as it existed immediately prior to the Closing) and its subsidiaries.</div><div>&#160;</div><div style="text-align: justify; color: rgb(0, 0, 0);">On the Closing Date, and in connection with the closing of the Business Combination, AMCI changed its name to Advent Technologies Holding, Inc. (the "Company" or "Advent"). Legacy Advent was deemed the accounting acquirer in the Business Combination based on an analysis of the criteria outlined in Accounting Standards Codification ("ASC") 805. This determination was primarily based on Legacy Advent's stockholders prior to the Business Combination having a majority of the voting interests in the combined company, Legacy Advent's operations comprising the ongoing operations of the combined company, Legacy Advent's board of directors comprising a majority of the board of directors of the combined company, and Legacy Advent's senior management comprising the senior management of the combined company. Accordingly, for accounting purposes, the Business Combination was treated as the equivalent of Legacy Advent issuing stock for the net assets of AMCI, accompanied by a recapitalization. The net assets of AMCI are stated at historical cost, with no goodwill or other intangible assets recorded.</div><div>&#160;</div><div style="text-align: justify; color: rgb(0, 0, 0);">While AMCI was the legal acquirer in the Business Combination, because Legacy Advent was deemed the accounting acquirer, the historical financial statements of Legacy Advent became the historical financial statements of the combined company, upon the consummation of the Business Combination. As a result, the unaudited condensed consolidated financial statements included in this report reflect (i) the historical operating results of Legacy Advent prior to the Business Combination; (ii) the results of the Company (combined results of AMCI and Legacy Advent) following the closing of the Business Combination; (iii) the assets and liabilities of Legacy Advent at their historical cost; and (iv) Company&#8217;s equity structure for all periods presented.</div><div>&#160;</div><div style="text-align: justify; color: rgb(0, 0, 0);">In accordance with guidance applicable to these circumstances, the equity structure has been restated in all comparative periods up to the Closing Date, to reflect the number of shares of the Company's common stock, $0.0001 par value per share ("Common Stock") issued to Legacy Advent's stockholders in connection with the recapitalization transaction. As such, the shares and corresponding capital amounts and earnings per share related to Legacy Advent Preferred Stock (&#8220;Preferred Series A&#8221; and &#8220;Preferred Series Seed&#8221;) and Legacy Advent common stock prior to the Business Combination have been retroactively restated as shares reflecting the exchange ratio established in the Business Combination Agreement. Activity within the statement of changes in stockholders' equity / (deficit) for the issuances of Legacy Advent's Preferred Stock, were also retroactively converted to Legacy Advent common stock.

The excess of the fair value of purchase consideration transferred over the fair values of these identifiable assets and liabilities is recorded as goodwill. In case the fair value of purchase consideration transferred is below fair values of these identifiable assets and liabilities, the Company recognizes a gain from a bargain purchase. Such valuations require management to make significant estimates and assumptions, especially with respect to intangible assets. Significant estimates in valuing certain intangible assets include, but are not limited to, future expected cash flows from acquired licenses, trade names, in process research and development ("R&amp;D"), useful lives and discount rates, patents, customer clientele, customer contracts and know-how. Management's estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. During the measurement period, the Company may record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period, any subsequent adjustments are recorded in the consolidated statement of operations.</div><div><br /></div><div style="text-align: justify; color: rgb(0, 0, 0);">For significant acquisitions, the Company obtains independent appraisals and valuations of the intangible (and certain tangible) assets acquired and certain assumed obligations. The Company analyzes each acquisition individually and all acquisitions within each reporting period in aggregate to determine if those are material acquisitions in the context of ASC 805-10-50.</div><div><br /></div><div style="text-align: justify; color: rgb(0, 0, 0);">The estimated fair values and useful lives of identified intangible assets are based on many factors, including estimates and assumptions of future operating performance and cash flows of the acquired business, estimates of cost avoidance, the nature of the business acquired, the specific characteristics of the identified intangible assets and our historical experience and that of the acquired business. The estimates and assumptions used to determine the fair values and useful lives of identified intangible assets could change due to numerous factors, including product demand, market conditions, regulations affecting the business model of our operations, technological developments, economic conditions and competition.</div><div><br /></div><div style="text-align: justify; color: rgb(0, 0, 0);">We conduct a goodwill impairment analysis annually in the fourth fiscal quarter, as of October 1, and as necessary if changes in facts and circumstances indicate that the fair value of our reporting units may be less than their carrying amounts. When indicators of impairment do not exist and certain accounting criteria are met, we are able to evaluate goodwill impairment using a qualitative approach. When necessary, our quantitative goodwill impairment test consists of two steps. The first step requires that we compare the estimated fair value of our reporting units to the carrying value of the reporting unit&#8217;s net assets, including goodwill. If the fair value of the reporting unit is greater than the carrying value of its net assets, goodwill is not considered to be impaired and no further testing is required. If the fair value of the reporting unit is less than the carrying value of its net assets, we would be required to complete the second step of the test by analyzing the fair value of its goodwill. If the carrying value of the goodwill exceeds its fair value, an impairment charge is recorded. Currently, we identify one reporting unit.</div></div><span></span>
