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 Company considers that the going concern basis is appropriate for the preparation of its consolidated financial statements, as it is pursuing additional fund raising as disclosed below and has no intentions to proceed with liquidation. The going concern basis of presentation assumes that the Company will continue in operation one year from the date these consolidated financial statements are issued and will be able to realize its assets and discharge its liabilities and commitments in the normal course of business. As such, the accompanying audited consolidated financial statements do not include any adjustments relating to the recoverability and classification of assets and their carrying amounts, or the amount and classification of liabilities that may result should the Company be unable to continue as a going concern. Following the significant non adjusting subsequent events of Advent Technologies A/S bankruptcy and the termination of the Hood Park lease agreement, the Company presents a Proforma Consolidated Balance Sheet as at December 31, 2023 in the Note 24 to the consolidated financial statements to reflect the impact of those events.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">In accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (Subtopic 205-40), the Company has evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern for one year from the date that the consolidated financial statements are issued. The Company’s ability to meet its liquidity needs will largely depend on its ability to raise capital in the very short term and generate cash in the future. During the year ended December 31, 2023, the Company used $32.1 <span id="xdx_90E_eus-gaap--NetCashProvidedByUsedInOperatingActivities_pn3n3_c20230101__20231231_zuuaVkOsPdod" style="display: none" title="Net cash used in operating activities">(32,115)</span> million of cash in operating activities, and the Company’s ability to raise and generate adequate capital and cash in the future is subject to general economic, financial, competitive, legislative, regulatory, and other factors that are beyond the Company’s control. Furthermore, the Company has suffered recurring operating losses and has a negative net working capital position of $<span id="xdx_90A_ecustom--NegativeNetWorkingCapital_iI_pn3n3_dm_c20231231_zXntCxxB6zOh" title="Negative net working capital">3.1</span> million as of December 31, 2023. In addition, as of the issuance date of these consolidated financial statements the Company is overdue in a number of its obligations which could give the right to creditors at any time from the issuance date of these consolidated financial statements to raise legal action against the Company which in turn could potentially lead to liquidation action against the Company and/or its subsidiaries. The transition to profitability and positive cash flow is highly dependent upon the successful development, approval, and commercialization of the Company’s products and the achievement of a revenue level adequate to support its cost structure and the Company can give no assurances that this will occur. Based on the Company’s current operating plan, the Company believes that its cash and cash equivalents as of December 31, 2023, of $<span id="xdx_904_eus-gaap--CashAndCashEquivalentsAtCarryingValue_iI_pn3n3_dm_c20231231__us-gaap--CashAndCashEquivalentsAxis__us-gaap--CashEquivalentsMember_z1iXXnfP9Me7" title="Cash and cash equivalents">3.6</span> million and $<span id="xdx_907_eus-gaap--CashAndCashEquivalentsAtCarryingValue_iI_pn3n3_dm_c20240812__us-gaap--CashAndCashEquivalentsAxis__us-gaap--CashEquivalentsMember_z7PYX0QIB8A3" title="Cash and cash equivalents">0.1</span> million as of August 12, 2024, are not sufficient to fund operations and capital expenditures for the twelve months following the filing of this Annual Report on Form 10-K, and the Company will need to obtain additional funding in the very near term, otherwise the Company may immediately substantially curtail or terminate its operations.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company performed a cash flow projection on a monthly basis for the twelve-month period following the issuance of the consolidated financial statements. With regards to the cash flow projections, the projected inflows from revenues and grants will be insufficient to cover the projected outflows, as such, the Company will continue to have a negative net working capital position and a delay in the projected timing of the short term financing and inflows and/or an immediate demand by creditors of repayment of the long outstanding payables may result in the Company being insolvent and short of cash at any specific time over the coming weeks and over the next twelve months.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The highlights of the projections are as follows:</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company projects cash inflows from contracted revenues and grants for which it has already signed agreements with third parties and estimates projected outflows assuming the effective implementation of the Company’s plans to reduce monthly expenditures gradually during 2024.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The cash flow projections do not include any cash inflows or outflows from Advent Technologies A/S which was declared bankrupt by the court in Aalborg, Denmark on July 25, 2024, and its wholly owned subsidiary Green Energy Philippines, Inc.

As part of its plan, on July 30, 2024, the Company entered into a securities purchase agreement, (the “Purchase Agreement”), with an institutional investor (the “Investor”) pursuant to which, at the closing, defined as the filing date of the Company’s 10-K, the Company will issue to the Investor a senior promissory note in the principal amount of $1 million (the “Senior Note”), repayable within one year and bearing interest of 18%. The Investor has also committed to provide the Company with a one-year revolving line of credit for an aggregate maximum principal amount of $2 million, again bearing interest of 18% (the two debt transactions are referred to as the “Financing”). The $2 million financing is contingent upon the Company’s filing of a Registration Statement on Form S-1 with the Securities and Exchange Commission with respect to an underwritten or “best efforts” public offering by the Company of its common stock, and/or common stock equivalents registered under the Securities Act of 1933, as amended for proceeds to the Company of not less than $5 million (a “Qualified Public Equity Offering”). The Company can give no assurances as of the date of issuance of the consolidated financial statements as to whether the Company will be successful in raising this Financing and executing a Qualified Public Equity Offering. The Company will use the proceeds from the Financing for general corporate purposes, including expenses related to the preparation of its Annual Report on Form 10-K for the year ended December 31, 2023, and expenses to facilitate a Qualified Public Equity Offering and the proceeds of the Qualified Public Equity Offering for general corporate purposes.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">With regards to the projected revenues and grants, a delay in the projected timing of inflows may result in the Company remaining insolvent and short of cash at any specific time over the next twelve months. Also, there is no guarantee that the Company’s plans to reduce monthly expenditures will be successful. Beyond that, there is no guarantee about when the Registration Statement in Form S-1 will be filed and therefore the committed one-year revolving line of credit of maximum $2 million will be received. In addition, there is no guarantee with regards to the Company’s ability to secure proceeds of not less than $5 million from the Qualified Public Entity Offering.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">If the Company is unable to obtain sufficient funding, it could be required to delay its development efforts, limit activities, and further reduce research and development costs, which could adversely affect its business prospects and delivery of contractual obligations. A cash shortfall at any point in time over the next twelve months could result in the Company failing to meet its overdue and current obligations which could trigger action against the Company and/or its subsidiaries for liquidation by employees, authorities, or creditors. Because of the uncertainty in securing additional funding, delays in growth of revenue, failure to materialize cost-cutting efforts and the insufficient amount of cash and cash equivalents as of the consolidated financial statement filing date, management has concluded that substantial doubt exists with respect to the Company’s ability to continue as a going concern for one year from the date the consolidated financial statements are issued.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0"> </p>

1. Basis of presentation: Overview Advent Technologies Holdings, Inc. and its subsidiaries (collectively referred to as “Advent” or the “Company”) 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. To date, Advent’s principal operations have been to develop and manufacture Membrane Electrode Assembly (MEA), and 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 Livermore, California, and the Company has MEA fabrication and system production facilities in Livermore, California and Patras, Greece. Previously, the Company’s headquarters were located in Boston, Massachusetts, which included a research and development and manufacturing facility. During 2023, the Company decided to consolidate certain of its German operations with its operations in Greece. During 2024, the Company closed its facilities in Boston, MA, and no longer maintains its facilities in Denmark and the Philippines due to the bankruptcy of Advent Technologies A/S. On February 4, 2021 (“Closing Date”), AMCI Acquisition Corp. (“AMCI”), consummated the previously announced business combination (the “Business Combination”) pursuant to that certain merger agreement (the “Agreement and Plan of Merger”), dated October 12, 2020, by and among AMCI, AMCI Merger Sub Corp., a Delaware corporation and newly formed wholly-owned subsidiary of AMCI (“Merger Sub”), AMCI Sponsor LLC (the “Sponsor”), solely in the capacity as the representative from and after the effective time of the Business Combination for the stockholders of AMCI, Advent Technologies, Inc., a Delaware corporation (“Legacy Advent”), and Vassilios Gregoriou, solely in his capacity as the representative from and after the effective time for the Legacy Advent stockholders (the “Seller Representative”), 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 “Closing”), AMCI acquired 100% of the stock of Legacy Advent (as it existed immediately prior to the Closing) and its subsidiaries. On the Closing Date, and in connection with the closing of the Business Combination, AMCI changed its name to Advent Technologies Holdings, 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. 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 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’s equity structure for all periods presented. 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, 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 (“Preferred Series A” and “Preferred Series Seed”) 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). On February 18, 2021, Advent Technologies, Inc. entered into a Membership Interest Purchase Agreement with Bren-Tronics, Inc. (“Bren-Tronics”) and UltraCell, LLC (“UltraCell”), a Delaware limited liability company and a direct wholly owned subsidiary of Bren-Tronics (the “UltraCell Purchase Agreement”). See Note 3 “Business Combination” for additional information. UltraCell LLC was renamed to Advent Technologies LLC following its acquisition by the Company. On June 25, 2021, the Company entered into a Share Purchase Agreement (the “Purchase Agreement”), with F.E.R. fischer Edelstahlrohre GmbH, a limited liability company incorporated under the Laws of Germany (the “Seller”) to acquire all of the issued and outstanding equity interests in SerEnergy A/S, a Danish stock corporation and a wholly-owned subsidiary of the Seller (“SerEnergy”) and fischer eco solutions GmbH, a German limited liability company and a wholly-owned subsidiary of the Seller (“FES”) together with certain outstanding shareholder loan receivables. See Note 3 “Business Combination” for additional information. SerEnergy and FES were renamed to Advent Technologies A/S and Advent Technologies GmbH, respectively, following their acquisition by the Company. The consolidated financial statements of the Company have been prepared to reflect the consolidation of the companies listed below: <table cellpadding="0" cellspacing="0" id="xdx_88C_ecustom--SubsidiariesInConsolidationTableTextBlock_pn3n3_zZqrlNtvdjel" style="font: 10pt Times New Roman, Times, Serif;

The Company considers that the going concern basis is appropriate for the preparation of its consolidated financial statements, as it is pursuing additional fund raising as disclosed below and has no intentions to proceed with liquidation. The going concern basis of presentation assumes that the Company will continue in operation one year from the date these consolidated financial statements are issued and will be able to realize its assets and discharge its liabilities and commitments in the normal course of business. As such, the accompanying audited consolidated financial statements do not include any adjustments relating to the recoverability and classification of assets and their carrying amounts, or the amount and classification of liabilities that may result should the Company be unable to continue as a going concern. Following the significant non adjusting subsequent events of Advent Technologies A/S bankruptcy and the termination of the Hood Park lease agreement, the Company presents a Proforma Consolidated Balance Sheet as at December 31, 2023 in the Note 24 to the consolidated financial statements to reflect the impact of those events. In accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (Subtopic 205-40), the Company has evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern for one year from the date that the consolidated financial statements are issued. The Company’s ability to meet its liquidity needs will largely depend on its ability to raise capital in the very short term and generate cash in the future. During the year ended December 31, 2023, the Company used $32.1 (32,115) million of cash in operating activities, and the Company’s ability to raise and generate adequate capital and cash in the future is subject to general economic, financial, competitive, legislative, regulatory, and other factors that are beyond the Company’s control. Furthermore, the Company has suffered recurring operating losses and has a negative net working capital position of $3.1 million as of December 31, 2023. In addition, as of the issuance date of these consolidated financial statements the Company is overdue in a number of its obligations which could give the right to creditors at any time from the issuance date of these consolidated financial statements to raise legal action against the Company which in turn could potentially lead to liquidation action against the Company and/or its subsidiaries. The transition to profitability and positive cash flow is highly dependent upon the successful development, approval, and commercialization of the Company’s products and the achievement of a revenue level adequate to support its cost structure and the Company can give no assurances that this will occur. Based on the Company’s current operating plan, the Company believes that its cash and cash equivalents as of December 31, 2023, of $3.6 million and $0.1 million as of August 12, 2024, are not sufficient to fund operations and capital expenditures for the twelve months following the filing of this Annual Report on Form 10-K, and the Company will need to obtain additional funding in the very near term, otherwise the Company may immediately substantially curtail or terminate its operations. The Company performed a cash flow projection on a monthly basis for the twelve-month period following the issuance of the consolidated financial statements. With regards to the cash flow projections, the projected inflows from revenues and grants will be insufficient to cover the projected outflows, as such, the Company will continue to have a negative net working capital position and a delay in the projected timing of the short term financing and inflows and/or an immediate demand by creditors of repayment of the long outstanding payables may result in the Company being insolvent and short of cash at any specific time over the coming weeks and over the next twelve months. The highlights of the projections are as follows: The Company projects cash inflows from contracted revenues and grants for which it has already signed agreements with third parties and estimates projected outflows assuming the effective implementation of the Company’s plans to reduce monthly expenditures gradually during 2024. The cash flow projections do not include any cash inflows or outflows from Advent Technologies A/S which was declared bankrupt by the court in Aalborg, Denmark on July 25, 2024, and its wholly owned subsidiary Green Energy Philippines, Inc. The Company did not include any outflows relating to Advent Technologies A/S, since it believes that the bankruptcy of its subsidiary, will not have any material effect, except for a potential claim of approximately $0.5 million from a supplier contract for which the parent company Advent Technologies Holdings, Inc. is the guarantor. In addition, the projections do not include any cash outflows relating to commitments and contingencies as disclosed in Note 22 to the consolidated financial statements, since the Company believes that any cash outflows relating to these commitments will not materialize based on the Company’s plans to agree the termination of such contracts with its suppliers and a contingent loss as outcome of the pending arbitration it is not probable. Until such time as the Company generates sufficient revenue to fund its operations (if ever), the Company plans to finance its operations and repay its existing and future liabilities and other obligations through the sale of equity and/or debt securities and, to the extent available, short-term and long-term loans. As part of its plan, on July 30, 2024, the Company entered into a securities purchase agreement, (the “Purchase Agreement”), with an institutional investor (the “Investor”) pursuant to which, at the closing, defined as the filing date of the Company’s 10-K, the Company will issue to the Investor a senior promissory note in the principal amount of $1 million (the “Senior Note”), repayable within one year and bearing interest of 18%. The Investor has also committed to provide the Company with a one-year revolving line of credit for an aggregate maximum principal amount of $2 million, again bearing interest of 18% (the two debt transactions are referred to as the “Financing”). The $2 million financing is contingent upon the Company’s filing of a Registration Statement on Form S-1 with the Securities and Exchange Commission with respect to an underwritten or “best efforts” public offering by the Company of its common stock, and/or common stock equivalents registered under the Securities Act of 1933, as amended for proceeds to the Company of not less than $5 million (a “Qualified Public Equity Offering”). The Company can give no assurances as of the date of issuance of the consolidated financial statements as to whether the Company will be successful in raising this Financing and executing a Qualified Public Equity Offering. The Company will use the proceeds from the Financing for general corporate purposes, including expenses related to the preparation of its Annual Report on Form 10-K for the year ended December 31, 2023, and expenses to facilitate a Qualified Public Equity Offering and the proceeds of the Qualified Public Equity Offering for general corporate purposes. With regards to the projected revenues and grants, a delay in the projected timing of inflows may result in the Company remaining insolvent and short of cash at any specific time over the next twelve months. Also, there is no guarantee that the Company’s plans to reduce monthly expenditures will be successful. Beyond that, there is no guarantee about when the Registration Statement in Form S-1 will be filed and therefore the committed one-year revolving line of credit of maximum $2 million will be received. In addition, there is no guarantee with regards to the Company’s ability to secure proceeds of not less than $5 million from the Qualified Public Entity Offering. If the Company is unable to obtain sufficient funding, it could be required to delay its development efforts, limit activities, and further reduce research and development costs, which could adversely affect its business prospects and delivery of contractual obligations. A cash shortfall at any point in time over the next twelve months could result in the Company failing to meet its overdue and current obligations which could trigger action against the Company and/or its subsidiaries for liquidation by employees, authorities, or creditors. Because of the uncertainty in securing additional funding, delays in growth of revenue, failure to materialize cost-cutting efforts and the insufficient amount of cash and cash equivalents as of the consolidated financial statement filing date, management has concluded that substantial doubt exists with respect to the Company’s ability to continue as a going concern for one year from the date the consolidated financial statements are issued.

Use Of Estimates

UseOfEstimates

Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. On an on-going basis, management evaluates the estimates and judgments, including those related to the selection of useful lives for tangible assets, expected future cash flows from long-lived assets to support impairment tests, the carrying value of goodwill, provisions necessary for accounts receivables and inventory write downs, provisions for legal disputes, and contingencies. Management bases its estimates and judgments on historical experience and on various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from those estimates under different assumptions and/or conditions.

The change in fair value is recognized in “Fair value change of warrant liability” on the consolidated statements of operations. The estimated fair value of the Private Placement Warrants and the Working Capital Warrants (each as defined below) is determined using Level 3 inputs by using the Black-Scholes model. The application of the Black-Scholes model requires the use of a number of inputs and significant assumptions including volatility. Significant judgment is required in determining the expected volatility of our common stock. Due to the limited history of trading of our common stock, we determined expected volatility based on a peer group of publicly traded companies.
