CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

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 “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “expect,” “should,” “could,” “target,” “predict,” “seek” 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 “Risk Factors” in this Quarterly Report on Form 10-Q and in our 2020 Annual Report on Form 10-K 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.

Some of the key factors that could cause actual results to differ include:


 •
our ability to maintain the listing of our shares of common stock and warrants on Nasdaq;

•
our ability to raise financing in the future;

•
our success in retaining or recruiting officers, key employees or directors;

•
factors relating to our business, operations and financial performance, including:

o
our ability to control the costs associated with our operations;

o
our ability to grow and manage growth profitably;

o
our reliance on complex machinery for our operations and production;

o
the market’s willingness to adopt our technology;

o
our ability to maintain relationships with customers;

o
the potential impact of product recalls;

o
our ability to compete within our industry;

o
increases in costs, disruption of supply or shortage of raw materials;

o
risks associated with strategic alliances or acquisitions, including the acquisition of SerEnergy A/S, a Danish stock corporation (“SerEnergy”) and fischer eco solutions GmbH, a German limited liability company (“FES”), former wholly-owned subsidiaries of F.E.R. fischer Edelstahlrohre GmbH, completed on August 31, 2021;

i

 o
the impact of unfavorable changes in U.S. and international regulations;

o
the availability of and our ability to meet the terms and conditions for government grants and economic incentives; and

o
our ability to protect our intellectual property rights;

•
market conditions and global and economic factors beyond our control, including the potential adverse effects of the ongoing global coronavirus (COVID-19) pandemic on capital markets, general economic conditions, unemployment and our liquidity, operations and personnel;

•
volatility of our stock price and potential share dilution; and

•
future exchange and interest rates.

The forward-looking statements included in this Quarterly Report on Form 10-Q are made only as of the date of this report. You should not rely upon forward-looking statements as predictions of future events. We cannot guarantee that the future results, levels of activity, performance or events and circumstances reflected in the forward-looking statements will be achieved or occur. Moreover, neither we nor any other person assumes responsibility for the accuracy and completeness of the forward-looking statements. We undertake no obligation to update publicly any forward-looking statements for any reason after the date of this Quarterly Report on Form 10-Q to conform these statements to actual results or reflect interim developments.

EXPLANATORY NOTE

This Quarterly Report on Form 10-Q contains our unaudited condensed consolidated financial statements for the three- and nine-month periods ended September 30, 2021.

We were originally incorporated in Delaware on June 18, 2018 under the name “AMCI Acquisition Corp.” 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 “Initial Public Offering”), following which our shares began trading on the Nasdaq Global Market (“Nasdaq”).

On February 4, 2021, we consummated the previously announced business combination (the “Business Combination”) pursuant to that certain Agreement and Plan of Merger, dated October 12, 2020, by and among AMCI Acquisition Corp. (the “Company”), AMCI Merger Sub Corp., a Delaware corporation and newly formed wholly-owned subsidiary of the Company (“Merger Sub”), AMCI Sponsor LLC (the “Sponsor”), solely in the capacity as the representative from and after the effective time of the Business Combination (as defined below) (the “Effective Time”) for the stockholders of the Company (other than the Advent stockholders) (the “Purchaser Representative”), Advent Technologies, Inc., a Delaware corporation (“Advent”), and Vassilios Gregoriou, solely in his capacity as the representative from and after the Effective Time for the Advent stockholders (the “Seller Representative”), as amended by Amendment No. 1 and Amendment No. 2 to the Agreement and Plan of Merger (the “Amendments” and as amended, the “Merger Agreement”), 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 “Closing”), we acquired 100% of the stock of Advent (as it existed immediately prior to the Closing) and its subsidiaries, changed our name from “AMCI Acquisition Corp.” to “Advent Technologies Holdings, Inc.” and changed the trading symbols of our common stock and warrants on Nasdaq from “AMCI” and “AMCIW” to “ADN” and “ADNWW,” respectively.

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 “Part I, Item 1. Unaudited Condensed Consolidated Financial Statements” and the notes thereto and in “Part I, Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations,” the financial information relating to the three and nine months ended September 30, 2020 are those of Advent and its subsidiaries; the financial information relating to the three months ended September 30, 2021, are those of the Company and its subsidiaries; and the financial information relating to the nine months ended September 30, 2021, are those 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 “Basis of Presentation” in the accompanying unaudited condensed consolidated financial statements for additional information.

Unless the context indicates otherwise, the terms “Advent,” the “Company,” we,” “us” and “our” refer to Advent Technologies Holdings, Inc. and its subsidiaries taken as a whole.

ADVENT TECHNOLOGIES HOLDINGS, INC.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
 
1.
Basis of presentation
 
(a)
Overview
 
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 (the “Purchaser Representative”), 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 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’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 ("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 (“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, the Company, entered into a Membership Interest Purchase Agreement with Bren-Tronics, Inc. (“Seller”) and UltraCell, LLC, a Delaware limited liability company and a direct wholly-owned subsidiary of Seller (“UltraCell”) (the “Purchase Agreement”). See Note 3 “Business Combination” accompanying the unaudited condensed consolidated financial statements for additional information.

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 (the “Acquisition”) 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” and together with SerEnergy, the “Target Companies”) together with certain outstanding shareholder loan receivables. See Note 3 “Business Combination” accompanying the unaudited condensed consolidated financial statements for additional information.

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, 2020 included in the Current Report on Form 8-K filed with the SEC on February 9, 2021 (the “Original Form 8-K”), as amended by Amendment No. 1 to Form 8-K, filed with the SEC on February 9, 2021 (“Amendment No. 1”), as further amended by Amendment No. 2 to Form 8-K, filed with the SEC on March 26, 2021 (“Amendment No. 2”) and as further amended by Amendment No 3 to Form 8-K, filed with the SEC on May 20, 2021 (“Amendment No. 3,” and, the Original Form 8-K, as so amended by Amendment No. 1, Amendment No. 2 and Amendment No. 3, the “Super Form 8-K”).
 
The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. Intercompany accounts and transactions have been eliminated.
 
Certain prior period balances have been reclassified to conform to the current period presentation in the unaudited condensed consolidated financial statements and the accompanying notes.
 
Share and per share amounts are presented on a post-conversion basis for all periods presented, unless otherwise specified.
 
(c)
Going Concern
 
The unaudited condensed consolidated financial statements have been prepared by management in accordance with GAAP, assuming that the Company will continue as a going concern, which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business. 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.
 
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’s business. The magnitude of the impact of the COVID-19 pandemic on the Company’s productivity, results of operations and financial position, and its disruption to the Company’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’s ability to conduct business in the ordinary course.
 
As of the date of this Quarterly Report on Form 10-Q, the Company’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.

2.
Summary of Significant Accounting Policies:

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 Super Form 8-K.

12
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 applied the following new accounting policies:

(a)
Business acquisitions, Goodwill and Intangible Assets

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&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.

For significant acquisitions, the Company obtains independent appraisals and valuations of the intangible (and certain tangible) assets acquired and certain assumed liabilities. 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.

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.

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’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.

(b)
Warrants

The Company may issue or assume common stock warrants with debt, equity or as standalone financing instruments that are recorded as either liabilities or equity in accordance with the respective accounting guidance. Warrants recorded as equity are recorded at their relative fair value or fair value determined at the issuance date and remeasurement is not required. Warrants recorded as liabilities are recorded at their fair value, within warrant liability on the consolidated balance sheets, and remeasured on each reporting date with changes recorded in revaluation of warrant liability on the Company's consolidated statements of operations.

13
(c)
Fair Value of Financial Instruments

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 $400,000 in connection with the closing of the Business Combination (the “Working Capital Warrants”) (Note 12). 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 Warrant Liability is remeasured to its fair value at each reporting period and upon settlement. The change in fair value is recognized in revaluation of warrant liability on the consolidated statements of operations. The change in fair value of the warrant liability is as follows:

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 table provides quantitative information regarding Level 3 fair value measurement inputs as of their measurement date September 30, 2021:

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

Earnings / (Loss) Per Share

Earnings / (Loss) Per Share is computed by dividing earnings / (loss) by the weighted average number of common shares outstanding during the period. Diluted earnings / (loss) per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted at the beginning of the periods presented, or issuance date, if later. The treasury stock method is used to compute the dilutive effect of warrants.

(e)
Stock-based Compensation
 

Stock-based compensation consists of stock options and restricted stock units (“RSUs”). Stock options and restricted stock units are equity classified and are measured at the fair market value of the underlying stock at the grant date. Under ASC 718, an entity may recognize compensation cost for an award with only a service condition that has a graded vesting schedule on either (1) an accelerated basis as though each separately vesting portion of the award was, in substance, a separate award or (2) a straight-line basis over the total requisite service period for the entire award. An entity’s use of either a straight-line or an accelerated attribution method represents an accounting policy election and thus should be applied consistently to all similar awards. The Company has elected to recognize compensation cost on a straight-line basis over the total requisite service period for the stock options and restricted stock units. This election does not affect the Company’s previous year results since the Restricted Stock Awards granted in the prior period did not have a service requirement and therefore the stock compensation expense was recognized immediately.  The Company has also a policy of accounting for forfeitures when they occur.

Recent Accounting pronouncements

Recently issued accounting pronouncements not yet adopted

In February 2016, the Financial Accounting Standards Board ("FASB") issued ASU 2016-02, Leases (Topic 842), to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. 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.  The new lease standard was originally effective for 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 “all other” 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.

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 is currently in the process of evaluating the effect of this guidance on the consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which is intended to simplify various aspects related to accounting for income taxes. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2020 for public entities, with early adoption permitted. ASU 2019-12 is effective for the Company beginning January 1, 2022, taking the exemption allowed for the “emerging growth companies” with early adoption permitted. The Company is currently evaluating the effects of this guidance on the Company's financial statements.

Business Combination

(a)
AMCI Acquisition Corp.
 
As detailed in Note 1 on February 4, 2021, the Company and AMCI consummated the Business Combination pursuant to the terms of the merger agreement, with Advent Legacy surviving the merger as a wholly-owned subsidiary 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 (“Closing Net Indebtedness”) 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.
 
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.
 
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.
 
15
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.
 
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 nine months ended September 30, 2021:

UltraCell, LLC
 
On February 18, 2021 (the “acquisition date”), pursuant to the terms and conditions of the Purchase Agreement, the Company acquired 100% of the issued and outstanding membership units of UltraCell from Bren-Tronics, Inc. The results of UltraCell’s operations have been included in the unaudited condensed consolidated financial statements since the acquisition date.
 
The Company has assessed provisions in ASC 805 and concluded that the UltraCell acquisition should be accounted as an acquisition of a business. The Company evaluated whether substantially all the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets and concluded that it is not. Since the “substantially all” threshold is not met, the Company further assessed whether the set acquired includes an input and a substantive process that together significantly contribute to the ability to create outputs. Following its assessment, the Company concluded that the minimum requirements to define UltraCell as a business are met.

UltraCell is an entity specialized in lightweight fuel cells for the portable power market with mature products and cutting-edge technology.

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’s former holders of membership interests, if UltraCell entered into certain customer arrangements for sales of products prior to June 30, 2021. On April 16, 2021 Advent paid the additional consideration based on UltraCell achieving completion of the terms of the contingent consideration.

The fair value of the assets acquired and liabilities assumed was based on a Purchase Price Allocation of UltraCell LLC conducted by an independent third party. The intangible assets recognized are the Trade Name “UltraCell” and the Patented Technology. The fair value measurement of the intangible assets has been performed by applying a combination of market, cost and income approach methods. The Trade Name was valued with the Relief-from-royalty method, which combines market & income approaches. The royalty rate used for the valuation of the Trade Name was 1.3%, which was determined from the market using databases from completed transactions at a global level while the discount rate used was 12.6%. The Patented Technology was valued with the multi period excess earnings method, which is an income approach. The discount rate used for the valuation of the Patented Technology was 11.6%. The Trade Name has an indefinite useful life while the Patented Technology has a useful life of 10 years.

Included in goodwill is the value of assembled workforce, which under FASB ASC topic 805, does not meet either the contractual-legal or the separability criterion in order to be separately valued as an intangible asset. As part of the acquisition, the Company acquired fully trained personnel thereby avoiding the expenditure that would have been required to hire and train equivalent personnel. Therefore, the assemblage cost avoided method was considered the most appropriate method for the valuation of the assembled workforce. The assembled workforce was valued at $0.19 million and has been included in goodwill.

(c)
Acquisition of SerEnergy and FES

Effective on August 31, 2021, pursuant to the previously announced Share Purchase Agreement (the “Purchase Agreement”), dated as of June 25, 2021, by and between Advent Technologies Holdings Inc. (the “Buyer”) and F.E.R. fischer Edelstahlrohre GmbH, a limited liability company incorporated under the Laws of Germany (the “Seller”), the Company acquired (the “Acquisition”) 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” and together with SerEnergy, the “Target Companies”) together with certain outstanding shareholder loan receivables.

17
The Company has assessed provisions in ASC 805 and concluded that the SerEnergy and FES acquisition should be accounted as an acquisition of a business. The Company evaluated whether substantially all the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets and concluded that it is not. Since the “substantially all” threshold is not met, the Company further assessed whether the set acquired includes an input and a substantive process that together significantly contribute to the ability to create outputs. Following its assessment, the Company concluded that the minimum requirements to define SerEnergy and FES as a business are met.

The results of the SerEnergy’s and FES’s operations have been included in the unaudited condensed consolidated financial statements since the acquisition date.

The revenues associated to SerEnergy and FES for the one-month period ended September 30, 2021 (acquisition date to September 30, 2021) was $791,626. The net loss associated to SerEnergy and FES for the one-month period ended September 30, 2021 (acquisition date to September 30, 2021) was $834,944.

If the acquisition had been consummated as of January 1, 2020, the Company’s pro-forma revenues and net loss for the nine months ended September 30, 2021 would have been $13.1 million and $(20.3) million, respectively, and for the nine months ended September 30, 2020 would have been $2.4 million and $(11.6) million, respectively. Similarly, pro-forma revenues and net loss for the three months ended September 30, 2021 would have been $3.9 million and $(13.1) million, respectively, and for the three months ended September 30, 2020 would have been $0.5 million and $(2.5) million, respectively. The unaudited pro forma results are for comparative purposes only and do not purport to be indicative of the results that would have actually been obtained if the acquisition had occurred at the beginning of the period presented. In addition, these results are not intended to be a projection of future results and do not reflect any synergies that might be achieved from the combined operations.

Pursuant to the Purchase Agreement, the Company acquired SerEnergy and FES, the fuel cell systems business of fischer Group. SerEnergy is a leading manufacturer of high-temperature polymer electrolyte membrane HT-PEM fuel cells and operates facilities in Aalborg, Denmark and in Manila, Philippines. FES operates in Achern, Germany and provides fuel-cell stack assembly and testing as well as the production of critical fuel cell components, including membrane electrode assemblies, bipolar plates and reformers.

As consideration for the transactions contemplated by the Purchase Agreement, the Company paid to the Seller $17,869,309 (€15,000,000) in cash (the “Cash Consideration”) and on August 31, 2021, the Company issued to the Seller 5,124,846 shares of common stock of the Company with a par value $0.0001 per share (the “Share Consideration”). The Share Consideration was capped to shares representing 9.999% of the Company’s common stock outstanding as of the completion (taking into account the common stock issued as Share Consideration, the “Cap”). An additional amount of $4,366,802, representing cash on the balance sheet of the acquired businesses at closing, will be paid to F.E.R. fischer Edelstahlrohre GmbH to complete the acquisition of SerEnergy and FES and is included in “Other current liabilities” (Note 10).

Transaction costs amounted to $889,716 and have been expensed in the condensed consolidated statement of operations under the caption “Administrative and selling expenses” in the accompanying condensed consolidated statement of operations.

The fair value of the assets acquired and liabilities assumed was based on a Purchase Price Allocation of SerEnergy and FES conducted by an independent third party.

The acquired businesses specialize in the manufacturing of hydrogen fuel cell systems and align with Advent’s ability to provide clean power in the stationary, remote, portable and off-grid markets under the “Any Fuel. Anywhere.” value proposition. The Company’s ability to deliver hydrogen through liquid fuels allows it to have immediate market opportunity today, without having to wait for the global hydrogen infrastructure to develop. The acquisitions also accelerate the Company’s strategy to cover the full vertical supply chain with its products and puts the Company in a competitive position to deliver reliable, efficient and cost-effective fuel cell systems with a new product portfolio of the latest high temperature-PEM fuel cells covering a range of 25W to 90kW systems. The acquisitions also make Advent a leading manufacturer of high temperature fuel cells across Europe and Asia. Expanding the business in Europe and Asia is a strategic move and allows the Company to have well-placed production capabilities and market penetration.

Included in goodwill is the value of assembled workforce, which under FASB ASC topic 805, does not meet either the contractual-legal or the separability criterion in order to be separately valued as an intangible asset. As part of the acquisition, the Company acquired fully trained personnel thereby avoiding the expenditure that would have been required to hire and train equivalent personnel. The assembled workforce included in goodwill was valued at $2.4 million applying the cost approach.

Goodwill is not expected to be deductible for tax purposes.

Intangible assets

The intangible assets recognized on the acquisition of SerEnergy and FES are as follows:

Patents
Two groups of patents are assumed to be the most significant drivers of future cash flows. The patents relate to improvements in gaskets, bipolar plates and cooling plates for fuel cells. The fair value of patents was determined by applying the multi-period excess earnings method which is an income approach. The discount rate used for the valuation of patents was 7.2%. Patents are amortized over 10 years since management assumes, that these groups of patents will continue to drive cash flows for 10 years, after which new patents will be of more relevance.

Process know-how (IPR&D)
SerEnergy and FES are currently developing cost reduction initiatives (unpatented know-how) related to membrane electrode assembly, bipolar plates, gaskets, burner/reformer and electronics. This IPR&D is evaluated as a significant asset for the business as it will allow significant cost reduction leading to higher profits in the future. These cost reductions are expected to be introduced beginning in 2022. The multi-period excess earnings method was applied to calculate the fair value of this asset. The discount rate used for the valuation of IPR&D was 10.1%. IPR&D is amortized over its useful life of 6 years, being the average timespan of a generation of fuel cell modules.

Order backlogs
Order backlogs recognized are in respect of two main customers of SerEnergy. The assessment of this asset was based on the total amount of order backlog attributable to these customers. The fair value was determined applying the income approach. Resulting cash flows after tax were discounted to present value by a minimal discount rate as the backlog’s timespan is less than a year.

12.
Private Placement Warrants and Working Capital Warrants:

In connection with the Business Combination, the Company has assumed 3,940,278 Private Placement Warrants issued upon AMCI’s Initial Public Offering. In addition, upon the closing of the Business Combination, the working capital loan provided by AMCI’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.

21
As of September 30, 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.

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 September 30, 2021, the Private Placement Warrants and Working Capital Warrants are held by its initial purchasers.

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’s evaluation of the provisions of ASC 815- 40-15, which provides that a warrant is not indexed to the issuer’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.

Stockholders’ Equity / (Deficit):

Shares Authorized

As of September 30, 2021, the Company had authorized a total of 111,000,000 shares for issuance with 110,000,000 shares designated as common stock, par value $0.0001 per share and 1,000,000 shares designated as preferred stock, par value $0.0001 per share.

Common Stock

On April 9, 2021, 22,798 common shares were issued in connection with the exercise of public warrants discussed below.

On August 31, 2021, 5,124,846 common shares were issued in connection with the share consideration for the acquisition of SerEnergy and FES discussed in Note 3(c).

As of September 30, 2021, the Company’s issued and outstanding common shares were 51,253,591.

Public Warrants
 
In connection with the Business Combination, the Company has assumed Public Warrants issued upon AMCI’s Initial Public Offering.

As of March 31, 2021, the Company had 22,052,077 Public Warrants outstanding. 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. During the second quarter of 2021, certain warrant holders exercised their option to purchase an additional 22,798 shares at $11.50. These exercises generated $262,177 additional proceeds to the Company and increased our shares outstanding by 22,798 shares. Following these exercises, as of September 30, 2021, the Company’s Public Warrants amounted to 22,029,279.

22
Once the warrants become exercisable, the Company may redeem the Public Warrants:

–
in whole and not in part;
–
at a price of $0.01 per warrant;
–
upon not less than 30 days’ prior written notice of redemption;
–
if, and only if, the reported last sale price of the Company’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
–
if, and only if, there is a current registration statement in effect with respect to the shares of common stock underlying such warrants.
 
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 “cashless basis,” 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’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.
 
Public Warrants are classified in equity in accordance with the Company’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’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.

Compensation Plans

The Company’s Board of Directors and shareholders previously approved the 2021 Equity Incentive Plan (the “Plan”) to reward certain employees and directors of the Company. The Plan has been established to advance the interests of the Company by providing for the grant to Participants of Stock and Stock-based Awards. The maximum number of shares of Stock that may be delivered in satisfaction of Awards under the Plan is 6,915,892 shares (the “Initial Share Pool”).

Stock Options

Pursuant to and subject to the terms of the 2021 Equity Incentive Plan the Company entered into separate Stock Option Agreements with each participant according to which each participant is granted an option (the “Stock Option”) to purchase up to a specific number of shares of Stock set forth in each agreement with an exercise price equal to the market price of Company’s stock at the date of grant. Stock options have been granted as follows:

The Stock Options are granted to each Participant in connection with their employment with the Company. The Stock Options vest on a graded basis over four years. The Company has a policy of recognizing compensation cost on a straight-line basis over the total requisite service period for the stock options. The Company has recognized compensation cost of $1,218,532 in respect of Stock Options granted, which is included in administrative and selling expenses in the statement of operations for the nine months ended September 30, 2021. The Company has also a policy of accounting for forfeitures when they occur.

As of September 30, 2021, there was $11.7 million of unrecognized compensation cost related to unvested stock options. This amount is expected to be recognized over the remaining vesting period of stock options.

Restricted Stock Units

Pursuant to and subject to the terms of the 2021 Equity Incentive Plan the Company entered into separate Restricted Stock Units (“RSUs”) with each participant. On the Grant Date of RSUs, the Company grants to each participant a specific number of RSUs as set forth in each agreement, giving each participant the conditional right to receive without payment one share of Stock. The RSUs are granted to each participant in connection with their ongoing employment with the Company. The Company has in place Restricted Stock Unit Agreements that vest within 1 year and Restricted Stock Unit Agreements that vest on a graded basis over four years.  The Company has a policy of recognizing compensation cost on a straight-line basis over the total requisite service period. The Company has recognized compensation cost of $2,790,176 in respect of RSUs, which is included in administrative and selling expenses in the statement of operations for the nine months ended September 30, 2021.

Stock Grant Plans

On March 26, 2020, the Company’s Board of Directors and shareholders approved the 2018-2020 Stock Grant Plan (the “2018-2020 Plan”) to reward certain employees and directors of the Company. The maximum aggregate number of shares that was able to be issued under the Plan was 1,280,199 common shares. The Company entered into separate Restricted Stock Award Agreements with each participant according to which awards for 1,280,199 shares of common stock were granted with a purchase price of $0.01 per share. Under the Plan, if the employee ceased to be employed with the Company for any reason prior to December 31, 2020, the Company had a limited repurchase period to repurchase the granted shares at a price of $0.01 per share. If the Company did not exercise such repurchase option and unless the Company declined in writing to exercise its repurchase option prior to such time, the repurchase option was automatically deemed exercised at the end of the repurchase window. This limited repurchase right lapsed upon the occurrence of a liquidation event. The repurchase feature was deemed equivalent to a forfeiture (vesting) provision. The shares vested over a period ending December 31, 2020. The stock-based compensation was recognized to administrative and selling expenses over the vesting period and based on the fair value of the shares on the grant date.

As of September 9, 2020, the Company’s Board of Directors and shareholders approved the 2020-2023 Stock Grant Plan (the “2020-2023 Plan”) to reward certain employees and directors of the Company. The maximum aggregate number of shares that was able to be issued under this plan was 893,503 common shares. The Company entered into separate Restricted Stock Award Agreements with each participant according to which awards for 893,503 shares of common stock were granted with a purchase price of $0.01 per share. If the Company did not exercise such repurchase option and unless the Company declined in writing to exercise its repurchase option prior to such time, the repurchase option was automatically deemed exercised at the end of the repurchase window. This limited repurchase right lapsed upon the occurrence of a liquidation event. The repurchase feature was deemed equivalent to a forfeiture (vesting) provision. The shares vested over a period ending December 31, 2020. The stock-based compensation was recognized to administrative and selling expenses over the vesting period and based on the fair value of the shares on the grant date.

The Company recognized compensation cost of $413,396 in respect of the Restricted Stock Awards granted, which is included in administrative and selling expenses in the statement of operations for the nine months ended September 30, 2020.

Fair value measurement:

The carrying amounts reflected in the consolidated balance sheets of cash and cash equivalents, accounts receivables, net, other current assets, trade and other payables, due from/to related parties, other current liabilities and income tax payable approximate their respective fair values due to the short maturity of these instruments.

16.
Income Taxes

To calculate the interim tax provision, at the end of each interim period the Company estimates the annual effective tax rate and applies that to its ordinary quarterly earnings. The effect of changes in the enacted 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.

17.
Commitments and contingencies:

17.1
Litigation

The Company is subject to legal and regulatory actions that arise from time to time in the ordinary course of business. The assessment as to whether a loss is probable or reasonably possible, and as to whether such loss or a range of such loss is estimable, often involves significant judgment about future events.

There is no material pending or threatened litigation against the Company that remains outstanding as of September 30, 2021.

17.2
Guarantee letters

The Company has contingent liabilities in relation to performance guarantee letters and other guarantees provided to third parties that arise from its normal business activity and from which no substantial charges are expected to arise. As of September 30, 2021, issued letters of guarantee amount to $2,776,164.

17.3

Net income (loss) per share is computed by dividing net income by the weighted-average number of shares of common stock outstanding during the period.
 
The following table sets forth the computation of the basic and diluted net income / (loss) per share for the three months ended September 30, 2021 and 2020 and the nine months ended September 30, 2021 and 2020.

Basic net income / (loss) per share is computed by dividing net income / (loss) for the periods presented by the weighted-average number of common shares outstanding during these periods.
 
Diluted net income /(loss) per share is computed by dividing the net income / (loss), by the weighted average number of common shares outstanding for the periods, adjusted for the dilutive effect of shares of common stock equivalents resulting from the assumed exercise of the Public Warrants, Private Placements Warrants, Working Capital Warrants, Stock Options and Restricted Stock Units. The treasury stock method was used to calculate the potential dilutive effect of these common stock equivalents.
 
As the Company incurred losses for the three month and nine month periods ended September 30, 2021 and 2020, the effect of including any potential common shares in the denominator of diluted per-share computations would have been anti-dilutive; therefore, basic and diluted losses per share are the same.

Subsequent Events


The Company evaluated subsequent events and transactions that occurred after the balance sheet date up to the date that the financial statements were issued. Based upon this review, the Company did not identify any subsequent events that would have required adjustment or disclosure in the financial statements.

Item 2.
Management’s Discussion and Analysis of Financial Condition and Results of Operations.
 
The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our unaudited condensed consolidated financial statements and related notes appearing elsewhere in this Quarterly Report on Form 10-Q, our Annual Report on Form 10-K for the year ended December 31, 2020, as filed with the Securities and Exchange Commission (the “SEC”) on March 26, 2021 (the “Original Annual Report”), as amended by Amendment No. 1 to Form 10-K, filed with the SEC on May 20, 2021 (as so amended, the “2020 Annual Report”), our quarterly reports on Form 10-Q for the three months ended March 31, 2021, filed with the SEC on May 20, 2021 (the “First Quarter Report”) and for the six months ended June 30, 2021, filed with the SEC on August 12, 2021, our Current Report on Form 8-K, as filed with the SEC on February 9, 2021 as further amended by Amendment No. 2 to Form 8-K, filed with the SEC on March 26, 2021 (“Amendment No. 2”) and as further amended by Amendment No 3 to Form 8-K, filed with the SEC on May 20, 2021 (“Amendment No. 3,” and, the Original Form 8-K, as so amended by Amendment No. 1, Amendment No. 2 and Amendment No. 3, the “Super Form 8-K”).
 
Some of the information contained in this discussion and analysis or set forth elsewhere in this Quarterly Report on Form 10-Q, including information with respect to our plans and strategy for our business, includes forward-looking statements that involve risks and uncertainties. As a result of many factors, including those factors set forth in the “Item 1A. Risk Factors” section of this Quarterly Report on Form 10-Q and the “Item 1A. Risk Factors” section of our 2020 Annual Report, our actual results could differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.
 
This MD&A generally discusses 2021 and 2020 items and year-over-year comparisons between 2021 and 2020. As used in this MD&A, unless the context indicates otherwise, the financial information and data relating to the three and nine months ended September 30, 2020 are those of Advent Technologies, Inc. and its subsidiaries, the financial information and data for the three months ended September 30, 2021 are those of Advent Technologies Holdings, Inc., and the financial information and data relating to the nine months ended September 30, 2021 are those of Advent Technologies, Inc. and its subsidiaries for the period prior to the Closing and are those of Advent Technologies Holdings, Inc. for the period subsequent to the Closing. See Note 1 “Basis of Presentation” in the accompanying unaudited condensed consolidated financial statements for additional information.
 
Overview
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’s core product offerings are full fuel cell systems and 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’s engineered membrane technology, enables a more robust, longer-lasting and ultimately lower-cost fuel cell product.
 
To date, Advent’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 production facilities in Greece, Denmark, Germany and Philippines. In 2022, Advent anticipates opening its new research and development and manufacturing facility at Hood Park in Charlestown, Massachusetts.
 
28
The majority of Advent’s current revenue derives from the sale of fuel cell systems and MEAs, as well as the sale of membranes and electrodes for specific applications in the iron flow battery and cellphone markets, respectively. While fuel cell systems and MEA sales and associated revenues are expected to provide the majority of Advent’s future income, both of these markets remain commercially viable and have the potential to generate material future revenues based on Advent’s existing customers. Advent has also secured grant funding for a range of projects from research agencies and other organizations. Advent expects to continue to be eligible for grant funding based on its product development activities over the foreseeable future.
 
Business Combination and Public Company Costs
 
On October 12, 2020, Advent Technologies, Inc. entered into the Merger Agreement with Advent Technologies Holdings, Inc. (formerly known as “AMCI”), a Delaware corporation, AMCI Merger Sub Corp., a newly-formed Delaware corporation and wholly-owned subsidiary of AMCI (“Merger Sub”), AMCI Sponsor LLC, a Delaware limited liability company (“Sponsor”), in its capacity as Purchaser Representative (the “Purchaser Representative”) and Vassilios Gregoriou, in the capacity as Seller Representative ( the “Seller Representative”), 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.’s financial statements for previous periods will be disclosed in the registrant’s current and future periodic reports filed with the SEC.

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 “reverse recapitalization.” 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 “Recapitalization”).

Upon consummation of the Business Combination, the most significant change in Advent’s reported financial position and results was an increase in cash of approximately $141 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.

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’ and officers’ liability insurance, director fees and additional internal and external accounting, legal and administrative resources, including increased audit and legal fees.

29
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:
 

 •
Expand U.S.-based operations to increase capacity for product testing, development projects and associated research and development activities;
 

 •
Expand production facilities to increase and automate assembly and production of fuel cell systems and MEAs;
 

 •
Develop improved MEA and other products for both existing and new markets, such as ultra-light MEAs designed for aviation applications, to remain at the forefront of the fast-developing hydrogen economy;
 

 •
Increase business development and marketing activities;
 

 •
Increase headcount in management and head office functions in order to appropriately manage Advent’s increased operations;
 

 •
Improve its operational, financial and management information systems;
 

 •
Obtain, maintain, expand, and protect its intellectual property portfolio; and
 

 •
Operate as a public company.
 
Change in Independent Registered Public Accounting Firm

On February 9, 2021, the audit committee of the board of directors of the Company approved the engagement of Ernst & Young (Hellas) Certified Auditors Accountants S.A. (“EY”) as the Company’s independent registered public accounting firm to audit the Company’s consolidated financial statements for the year ending December 31, 2021. EY served as independent registered public accounting firm of Advent prior to the Business Combination. Accordingly, Marcum LLP (“Marcum”), the Company’s independent registered public accounting firm prior to the Business Combination, was informed that it would be replaced by EY as the Company’s independent registered public accounting firm following completion of its audit of the Company’s financial statements for the fiscal year ended December 31, 2020, which consists only of the accounts of the pre-Business Combination special purpose acquisition company.

Pursuant to the Purchase Agreement, the Company acquired SerEnergy and FES, the fuel cell systems business of fischer Group. SerEnergy is a leading manufacturer of methanol-powered high-temperature polymer electrolyte membrane (“HT-PEM”) fuel cells and operates facilities in Aalborg, Denmark and in Manila, Philippines. FES provides fuel-cell stack assembly and testing as well as the production of critical fuel cell components of the SerEnergy HT-PEM fuel cells, including membrane electrode assemblies, bipolar plates and reformers. FES operates a facility on fischer Group’s campus in Achern, Germany, and Advent agreed to lease that respective portion of the facility at the closing of the Acquisition.

Announced Projects White Dragon & Green HiPo (4.65GW Green Hydrogen & 400MW Fuel Cells), approved by Greek Government and submitted to EU

On September 7, 2021, Advent announced that two Greek Important Projects of Common European Interest (“IPCEI”) had been approved by the Greek Minister of Development and Investments and the Greek Minister of Environment, Energy, and Climate Change. The programs submitted by Advent and the White Dragon consortium of companies aspire to replace Greece’s largest coal-fired plants with renewable solar energy parks, which will be supported by green hydrogen production (4.65GW), and fuel cell heat and power production (400MW). The projects are part of the "Hydrogen Technologies" IPCEI and will now move towards approval at the European Union ("EU") level. As a next step, Advent will demonstrate before the European Commission the economic, environmental, financial, social, and technical feasibility of the projects and the positive spillover effects to the European economy and society. Advent hopes to receive final notification from the European Commission by mid-2022. If approved, the Company will be the technology partner for an €8 billion project.

Collaboration with the DOE

The efforts with the constellation of Department of Energy National Laboratories (Los Alamos National Laboratory, LANL; Brookhaven National Laboratory, BNL; National Renewable Energy Laboratory, NREL) continue to gain momentum. This group of leading scientists and engineers is working closely with Advent’s development and manufacturing teams and are furthering the understanding of breakthrough materials that will advance HT-PEM fuel cells.  This next generation HT-PEM is well suited for heavy duty transportation, marine, and aeronautical applications, as well as delivering benefits in cost and lifetime for stationary power systems used in telecom and other remote power markets.

Advent Launches New Product Line, M-ZERØ™ Fuel Cells, to Significantly cut Methane Emissions in North America

Comparability of Financial Information

Advent’s results of operations and statements of assets and liabilities may not be comparable between periods as a result of the Business Combination.
 
Key Factors Affecting Our Results
 
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.

Increased Customer Demand

Based on conversations with existing customers and incoming inquiries from new customers, Advent anticipates substantial increased demand for its fuel cell systems and 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 September 30, 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.

Successful development of the Advanced MEA product

Advent’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 (“Advanced MEA”) which is anticipated to deliver as much as three times the power output of its current MEA product. While 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’s customers.

Components of Results of Operations

Revenue, net
 
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 fuel cell systems and MEA sales over time, in line with the projected increase in MEA production in response to customer demand.
 
Cost of Revenues
 
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 systems and electrodes. Advent expects cost of revenues to increase substantially in line with increased production.
 
Income from Grants

Income from grants consists of cash subsidies received from research agencies and other national and international organizations in support of Advent’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.
 
Research and Development Expenses

Research and development expenses consist of costs associated with Advent’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.

Administrative and Selling Expenses
 
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 and stock-based compensation expense. 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.

33
Other Income / Expenses
 
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.

Change in Fair Value of Warrant Liability
 
Change in fair value of warrant liability amounting to $15.8 million for the nine months ended September 30, 2021 represents the change in fair value of the Private Placement Warrants and Working Capital Warrants from February 4, 2021 to September 30, 2021.

Finance Costs

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.

Foreign exchange differences, net
 
Foreign exchange differences, net consists of foreign exchange gains or losses 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 portion of the Company’s costs are denominated in euros.

Amortization of intangibles

The intangible assets of $4.7 million recognized on the acquisition of UltraCell is the Trade Name “UltraCell” ($0.4 million) and the Patented Technology ($4.3 million). The Trade Name has an indefinite useful life while the Patented Technology has a useful life of 10 years, for which amortization expense of $(0.3) million has been recognized for the period from the acquisition date of UltraCell to September 30, 2021.

The intangible assets of $20.1 million recognized on the acquisition of SerEnergy and FES are the Patents amounting to $17.3 million, the Process know-how (IPR&D) amounting to $2.6 million and the Order backlog amounting to $0.2 million. The Patents have a useful life of 10 years, the Process know-how has a useful life of 6 years and the Order backlog has a useful life of 1 year.  Amortization expense of $(0.2) million has been recognized in relation to these intangibles for the period from the acquisition date of SerEnergy and FES to September 30, 2021.

Income tax
Income tax amounting to $0.05 million for the nine months ended September 30, 2021 mainly relates to deferred income tax in respect to the intangible assets recognized upon the acquisition of SerEnergy and FES.

Revenue, net
 
Our total revenue from product sales increased by approximately $1.4 million or 642.6% from approximately $0.2 million in the three months ended September 30, 2020 to approximately $1.7 million in the three months ended September 30, 2021. The increase in revenue was related to a) increased demand from customers for Advent’s MEAs and other products, as a result of Advent’s customers increasing their own testing and usage of Advent’s products, b) revenue from UltraCell’s operations (acquired on February 19, 2021) and c) revenue from SerEnergy and FES’s operations (acquired on August 31, 2021).

Cost of Revenues

Cost of revenues increased by approximately $1.5 million from approximately $0.1 million in the three months ended September 30, 2020 to approximately $1.6 million in the three months ended September 30, 2021. The increase in cost of revenues was directly related to the increased revenues and the requirement for increased production of MEAs and fuel cell systems to satisfy customer demand, as well as, cost of revenues attributed to UltraCell’s, SerEnergy’s and FES’s operations.

Gross profit, which is revenue, net minus the cost of revenue, decreased to $0.03 million in the three months ended September 30, 2021 from $0.1 million for the three months ended September 30, 2020.

35
Research and Development Expenses

Research and development expenses were approximately $0.9 million in the three months ended September 30, 2021, primarily related to the Company’s cooperative research and development agreement with the U.S. Department of Energy, as well as the research and development costs of SerEnergy and FES in the month of September.

Administrative and Selling Expenses

Administrative and selling expenses were approximately $13.0 million in the three months ended September 30, 2021, and $0.9 million in the three months ended September 30, 2020. The increase was primarily due to the increased number of employees from period to period in the Greece and Boston offices, as well as the recognition of stock-based compensation expense of $3.4 million in the three months ended September 2021, costs related to the acquisition of SerEnergy/FES and a non-recurring $2.4 million charge for executive severance.

Change in fair value of Warrant Liability

The change in fair value of warrant liability amounting to $2.4 million was due to the change in fair value of the Private Placement Warrants and Working Capital Warrants during the three months ended September 30, 2021.
