NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Overview

Advent Technologies Holdings, Inc. and its subsidiaries (collectively referred to as “Advent” and 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 Boston, Massachusetts, which includes a research and development and manufacturing facility, a product development facility in Livermore, California, production facilities in Greece, Denmark, and Germany, and sales and warehousing facilities in the Philippines.

On February 4, 2021 (“Closing Date”), AMCI Acquisition Corp. (“AMCI”), consummated the 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. 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.

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.

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, 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.

SerEnergy and FES were renamed to Advent Technologies A/S and Advent Technologies GmbH, respectively, following their acquisition by the Company on August 31, 2021.

The unaudited condensed consolidated financial statements of the Company have been prepared to reflect the consolidation of the companies listed below:

Unaudited Condensed Consolidated Financial Statements

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”) and pursuant to the regulations of the U.S. Securities and Exchange Commission (“SEC”). 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, 2022, included in the Annual Report on Form 10-K filed with the SEC on March 31, 2023.

The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. Intercompany accounts and transactions have been eliminated.

Share and per share amounts are presented on a post-conversion basis for all periods presented, unless otherwise specified.

Going Concern

The accompanying unaudited condensed consolidated financial statements have been prepared assuming the Company will continue as a going concern. The going concern basis of presentation assumes that the Company will continue in operation one year from the date these unaudited condensed 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 unaudited condensed 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.

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 unaudited condensed consolidated financial statements are issued. The Company’s ability to meet its liquidity needs will largely depend on its ability to generate cash in the future. During the three months ended March 31, 2023, the Company used $11.4 million of cash in operating activities, and the Company’s ability to generate cash in the future is subject to general economic, financial, competitive, legislative, regulatory, and other factors that are beyond the Company’s control. The transition to profitability is dependent upon the successful development, approval, and commercialization of its products and the achievement of a revenue level adequate to support its cost structure. Based on the Company’s current operating plan, the Company believes that its cash and cash equivalents as of March 31, 2023 of $19.5 million will not be sufficient to fund operations and capital expenditures for the twelve months following the filing of this Quarterly Report on Form 10-Q, and the Company will need to obtain additional funding. In July 2022, the Company received official ratification from the European Commission of the European Union for one of the Important Projects of Common European Interest (“IPCEI”), Green HiPo. This project provides for the availability of funding of €782.1 million over the next six years. As of the issuance date of the unaudited condensed consolidated financial statements, the Company has not received an agreement which provides the terms of the funding. In addition, on April 10, 2023, the Company entered into a purchase agreement (the “Purchase Agreement”) with Lincoln Park Capital Fund, LLC (“Lincoln Park”), which provides that the Company has the right, but not the obligation, to sell to Lincoln Park up to $50 million worth of shares of the Company’s common stock, par value $0.0001 (the “Common Stock”), from time to time over the 36 month term of the Purchase Agreement. Concurrently with entering into the Purchase Agreement, the Company also entered into a registration rights agreement with Lincoln Park, pursuant to which the Company agreed to register the resale of the shares of the Company’s Common Stock that have been and may be issued to Lincoln Park under the Purchase Agreement pursuant to a registration statement (the “Registration Statement”). The Registration Statement was filed on April 21, 2023 and declared effective on May 2, 2023. Per the terms of the Purchase Agreement, the Company will be unable to sell shares of the Company’s Common Stock to Lincoln Park if the sale price falls below $0.50 per share. Therefore, there is no assurance that the Company will have full access to the facility over the next twelve months. If the Company is unable to obtain sufficient funding, it could be required to delay its development efforts, limit activities and reduce research and development costs, which could adversely affect its business prospects. Because of the uncertainty in securing additional funding and the insufficient amount of cash and cash equivalents as of the 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 unaudited condensed consolidated financial statements are issued.

There have been no significant changes from the significant accounting policies disclosed in Note 2 of the “Notes to Consolidated Financial Statements” included in the Annual Report Form 10-K filed with the SEC on March 31, 2023.

The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart our Business Startups Act of 2012, (the “JOBS Act”). As an emerging growth company (“EGC”), 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 did not apply any new accounting policies during the three- month period ended March 31, 2023 other than those noted below.

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.

Cash, Cash Equivalents, Restricted Cash and Restricted Cash Equivalents

Cash and cash equivalents are highly liquid investments with original maturities of three months or less. Cash and cash equivalents consist of cash on hand, deposits held on call with banks and investments in money market funds with original maturities of three months or less at the date of acquisition. As of March 31, 2023 and December 31, 2022, the Company has cash and cash equivalents which are restricted of $0.8 million. The restricted cash equivalent is a letter of credit required by the Company’s lease agreement for the Hood Park facility in Boston, MA. The letter of credit is required for the duration of the lease agreement which has a term of eight years. The lease commenced in October 2022.

The Company reconciles cash, cash equivalents, restricted cash and restricted cash equivalents reported in the consolidated balance sheets that aggregate to the beginning and ending balances shown in the unaudited condensed consolidated statements of cash flows as follows:

Warranties

The Company provides a warranty on fuel cells we sell for typically 2 years. The Company accrues a warranty reserve of 8% of the sale price of the fuel cells sold, which includes the Company’s best estimate of the projected costs to repair or replace items under warranties and recalls when identified. Warranty reserve is released when repairs or replacements are carried out in relation to items under warranties or when the warranty period for the fuel cell expires. The portion of the warranty reserve expected to be incurred within the next 12 months is included within Other current liabilities, while the remaining balance is included within Other long-term liabilities on the unaudited condensed consolidated balance sheets. Warranty expense is recorded as a component of cost of revenue in the unaudited condensed consolidated statements of operations.

The changes in the accrued warranty reserve for the three months ended March 31, 2023 and 2022 were as follows:

Credit Losses

In June 2016, the FASB issued ASU 2016-13, Financial Instruments—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. The Company adopted the standard on January 1, 2023, in accordance with the adoption dates for private entities applicable to it under its emerging growth company status and the standard did not have a material impact on the Company’s unaudited condensed consolidated financial statements and related disclosures. The Company is exposed to credit losses primarily through sales of its products. The Company assesses each customer’s ability to pay and a credit loss estimate by conducting a credit review which includes consideration of established credit rating or an internal assessment of the customer’s creditworthiness based on an analysis of their payment history when a credit rating is not available. The Company monitors credit exposure through active review of customer balances. The Company’s expected loss methodology for accounts receivable is developed through consideration of factors including, but not limited to, historical collection experience, current customer credit ratings, current customer financial condition, current and future economic and market conditions, and age of the receivables. Charges related to credit losses are included in administrative and selling expenses and are recorded in the period that the outstanding receivables are determined to be doubtful. Account balances are written-off against the allowance when they are deemed uncollectible.

Sublease

On January 9, 2023, the Company entered into a sublease agreement by and among the Company, in its capacity as sublandlord, BP Hancock LLC, a Delaware limited liability company, in its capacity as landlord, and Hughes Boston, Inc. (“Hughes”), in its capacity as subtenant. The sublease provides for the rental by Hughes of office space at 200 Clarendon Street, Boston, MA 02116. Under the terms of the sublease, Hughes subleases 6,041 square feet at an initial fixed annual rent of $0.6 million and will increase 3.0% on each anniversary of the sublease commencement date. The term of the sublease is through March 2026 (unless terminated as provided in the sublease) and the sublease commencement date was February 1, 2023. The sublease agreement has been classified as operating lease agreement, considering the ASU 842 classification criteria. During the three months ended March 31, 2023, the Company recognized $0.1 million in rent income which is included within other income in the unaudited condensed consolidated statement of operations.

Fair Value Measurements

The Company follows the accounting guidance in ASC 820 for its fair value measurements of financial assets and liabilities measured at fair value on a recurring basis. Fair value is defined as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability.

The accounting guidance requires fair value measurements be classified and disclosed in one of the following three categories:

The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

Convertible Bond Loan

On May 25, 2022, Advent Technologies S.A (“Advent SA”) and UNI.FUND Mutual Fund (“UNIFUND”) entered into an agreement to finance Cyrus SA (“Cyrus”) with a convertible bond loan (“Bond Loan”) of €1.0 million. As a part of this transaction, Advent SA offered €0.3 million in bond loans with an annual interest rate of 8.00%. The term of the loan is three years and there is a surcharge of 2.5% for overdue interest.

Cyrus business relates to the research and experimental development in natural sciences and mechanics, the construction of pumps and hydrogen compressors and the wholesale of compressors. Hydrogen compressors are a critical part of the Hydrogen Refueling Stations (HRS) to be used by transport applications. Cyrus has developed a prototype Metal Hydride Compressor which offers unique advantages. The proceeds from the Bond Loan are to cover Cyrus’s working capital needs in the context of its operation and the product development.

Mandatory conversion of the Bond Loan will occur in the event of qualified financing which is equivalent to a share capital increase by Cyrus in the first three years from the execution of the Bond Loan agreement with a total amount over €3 million which is covered by third parties unrelated to the basic shareholders or by investors related to them.

The Company classifies the Bond Loan as an available for sale financial asset on the consolidated balance sheets. The Company recognizes interest income within the consolidated statement of operations. For the three months ended March 31, 2023, the Company recognized $7 thousand of interest income related to the Bond Loan within the consolidated statements of operations. The Company did not recognize any interest income related to the Bond Loan during the three months ended March 31, 2022.

The Company initially measured the available for sale Bond Loan at the transaction price plus any applicable transaction costs. The Bond Loan is remeasured to its fair value at each reporting period and upon settlement. The estimated fair value of the Bond Loan is determined using Level 3 inputs by using a discounted cash flow model. The change in fair value is recognized within the consolidated statements of comprehensive loss. The Company did not recognize any unrealized gain / (loss) during the three months ended March 31, 2023.

Warrant Liability

As a result of the Business Combination, the Company assumed a warrant liability (the “Warrant Liability”) related to previously issued 3,940,278 warrants, each exercisable to purchase one share of common stock at an exercise price of $11.50 per share, originally sold to AMCI Sponsor LLC (the “Sponsor”) in a private placement consummated in connection with AMCI’s initial public offering (the “Private Placement Warrants”) and the 400,000 warrants, each exercisable to purchase one share of Common Stock at an exercise price of $11.50 per share, converted from the Sponsor’s non-interest bearing loan to the Company of $0.4 million in connection with the closing of the Business Combination (the “Working Capital Warrants”) (Note 14). The Private Placement Warrants and the Working Capital Warrants have substantially the same terms as the 22,029,279 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 “Public Warrants”).

The following tables summarize the fair value of the Company’s assets and liabilities measured at fair value on a recurring basis as of March 31, 2023 and December 31, 2022.

The carrying amounts of the Company’s remaining financial instruments reflected on the consolidated balance sheets and which consist of cash and cash equivalents, accounts receivables, net, other current assets, trade and other payables, and other current liabilities, approximate their respective fair values due to their short-term nature.

Changes in the fair value of Level 3 assets and liabilities for the three months ended March 31, 2023 and 2022 were as follows:

The Warrant Liability is remeasured to its fair value at each reporting period and upon settlement. 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.

The following tables provide quantitative information regarding Level 3 fair value measurement inputs as of their measurement date March 31, 2023:

The Company performs routine procedures such as comparing prices obtained from independent source to ensure that appropriate fair values are recorded.

Intangible Assets

Information regarding our intangible assets, including assets recognized from our acquisitions, as of March 31, 2023 and December 31, 2022 is as follows:

The Company did not record any additions to indefinite-lived intangible assets during the three months ended March 31, 2023 and 2022.

In 2021, the Company recorded $22.9 million (net carrying amount) of amortizing intangible assets, most of which were in connection with the Company’s acquisitions of UltraCell, SerEnergy, and FES. The amortizing intangible assets consist of patents, process know-how (IPR&D), order backlogs, and software which are amortized over 10 years, 6 years, 1 year, and 5 years respectively. The amortization expense for the intangible assets for the three months ended March 31, 2023 and 2022 was $0.2 million and $0.7 million, respectively.

Amortization expense is recorded on a straight-line basis. Assuming constant foreign currency exchange rates and no change in the gross carrying amount of the intangible assets, future amortization expense related to the Company’s intangible assets subject to amortization as of March 31, 2023 is expected to be as follows:

The Company’s property, plant and equipment, net, consisted of the following:

During the three months ended March 31, 2022, additions to property, plant and equipment of $0.9 million include leasehold improvements, machinery, office and other equipment and assets under construction.

Assets under construction mainly relate to the design and construction of Company’s leased premises at Hood Park in Charlestown, MA. Completed assets are transferred to their respective asset classes, and depreciation begins when an asset is ready for its intended use. During the three months ended March 31, 2023 and 2022, the Company did not transfer assets under construction to machinery and equipment.

Depreciation expense during the three months ended March 31, 2023 and 2022 was $0.4 million and $0.4 million, respectively.
