Introductory Note
Business Combination
On February 4, 2021 (the “Closing Date”), AMCI Acquisition Corp., a Delaware corporation (“AMCI” and after the Business Combination described herein, “New Advent”), consummated the previously announced business combination (the “Closing”) pursuant to the terms of the Agreement and Plan of Merger dated as of October 12, 2020 (as amended on October 19, 2020 and amended again on December 31, 2020, the “Merger Agreement”) by and among AMCI, 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 thereunder (the “Purchaser Representative”), Advent Technologies Inc., a Delaware corporation (“Advent”) and Vassilios Gregoriou, in the capacity as the Seller Representative thereunder (the “Seller Representative”). Pursuant to the terms of the Merger Agreement, Merger Sub merged with and into Advent with Advent continuing as the surviving corporation and as a wholly owned subsidiary of AMCI (the “Merger” and together with the other transactions contemplated by the Merger Agreement, the “Business Combination”). In connection with the Closing, AMCI changed its name to “Advent Technologies Holdings, Inc.”
In accordance with the terms and subject to the conditions set forth in the Merger Agreement, at the effective time of the Merger (the “Effective Time”):
(i) the outstanding shares of Class A common stock, par value $0.0001 per share, of AMCI (“AMCI Class A common stock”), including any shares of Class B common stock, par value $0.0001 per share, of AMCI (“AMCI Class B common stock”, and together with the AMCI Class A common stock, the “AMCI common stock”) that were converted into AMCI Class A common stock in accordance with AMCI’s amended and restated certificate of incorporation, were redesignated as common stock, par value $0.0001 per share, of Advent Technologies Holdings, Inc. (referred to herein as “New Advent common stock”);
(ii) each share of common stock, par value $0.001 per share, of Advent (“Advent common stock”) and each share of preferred stock, par value $0.001 per shares, of Advent (“Advent preferred stock” and, together with the Advent common stock, the “Advent stock”) was cancelled and converted into the right to receive a number of new shares of New Advent common stock, in each case determined in accordance with the terms and conditions of the Merger Agreement; and
(iii) all outstanding options, warrants or rights to subscribe for or purchase any capital stock of Advent or securities convertible into or exchangeable for, or that otherwise confer on the holder any right to acquire any capital stock of Advent (“Advent Convertible Securities”) that were not exercised or converted prior to the Effective Time were cancelled, retired and terminated.
The aggregate Merger consideration being paid to holders of Advent stock as of immediately prior to the Effective Time (“Advent stockholders”) is an amount equal to (the “Merger Consideration”) $250,000,000, minus the estimated consolidated indebtedness of Advent and its subsidiaries as of the consummation of the Business Combination, net of their estimated consolidated cash and cash equivalents (“Closing Net Indebtedness”). The Merger Consideration is being paid solely by the delivery of new shares of New Advent common stock, each valued at $10.00 per share (the “Merger Consideration Shares”). The Closing Net Indebtedness (and the resulting Merger Consideration) is based solely on estimates determined shortly prior to the Closing and is not subject to any post-Closing true-up or adjustment. The Merger Consideration is being allocated among Advent stockholders based on their pro rata ownership in Advent as of immediately prior to the Effective Time (treating Advent preferred stock on an as-converted to Advent common stock basis for such purposes and including Advent Convertible Securities that have exercised or converted prior to the Effective Time).
Immediately prior to the Closing, AMCI had $400,000 in a working capital, non-interest bearing loan from Sponsor outstanding. In connection with the Closing, Sponsor elected to convert such working capital loan into 400,000 warrants to purchase shares of New Advent common stock at a price of $1.00 per warrant. The working capital warrants are identical to the warrants issued to Sponsor in a private placement consummated simultaneously with the initial public offering of AMCI, including as to exercise price, exercisability and exercise period.
The foregoing description of the Business Combination does not purport to be complete and is qualified in its entirety by the full text of the Merger Agreement, which is attached hereto as Exhibit 2.1, Exhibit 2.2 and Exhibit 2.3 and is incorporated herein by reference.

PIPE
On December 22, 2020, AMCI entered into subscription agreements (“PIPE Subscription Agreements”) by and among AMCI and the investors named therein (the “PIPE Investors”), pursuant to which the PIPE Investors agreed to purchase, and AMCI agreed to sell to the PIPE Investors, an aggregate of 6,500,000 shares of AMCI Class A common stock for gross proceeds to AMCI of $65,000,000 in a private placement (the “PIPE Investment”). The PIPE Investment was consummated substantially concurrently with the Business Combination.
The foregoing description of the PIPE Subscription Agreements does not purport to be complete and is qualified in its entirety by reference to the full text of the form of the PIPE Subscription Agreement, which is attached hereto as Exhibit 10.1 and is incorporated herein by reference.
Unless the context otherwise requires, in this Current Report on Form 8-K, the “registrant” and the “Company” refer to AMCI prior to the Closing and to the combined company and its subsidiaries following the Closing and “Advent” refers to Advent and its subsidiaries prior to the Closing and the business of the combined company and its subsidiaries following the Closing.
Immediately after giving effect to the PIPE Investment and the Business Combination, there were 46,105,947 shares of New Advent common stock outstanding and 26,392,355 warrants to purchase shares of New Advent common stock outstanding.
Item 2.01 Completion of Acquisition or Disposition of Assets.
On February 2, 2021, AMCI held a Special Meeting at which the AMCI stockholders considered and adopted, among other matters, the Merger Agreement (the “Special Meeting”). On February 4, 2021, the parties to the Merger Agreement consummated the Business Combination. Pursuant to the Merger Agreement, the Merger Consideration paid to the Advent stockholders is being paid solely by the delivery of new shares of New Advent common stock, each valued at $10.00 per share. The aggregate value of the consideration paid to Advent stockholders in the Business Combination was approximately $250.3 million.
Prior to the Special Meeting, holders of 1,606 shares of AMCI’s Class A common stock sold in its initial public offering exercised their right to redeem those shares for cash at a price of approximately $10.30 per share, for an aggregate of $16,536.64.
In connection with the Closing, New Advent common stock and warrants began trading on The Nasdaq Stock Market LLC (“Nasdaq”) under the symbols “ADN” and “ADNWW”. AMCI’s public units automatically separated into their component securities upon consummation of the Business Combination and, as a result, no longer trade as a separate security.
As of the Closing Date, our directors and executive officers and affiliated entities beneficially owned approximately 26.1% of the outstanding shares of New Advent common stock, and the former securityholders of AMCI beneficially owned approximately 31.6% of the outstanding shares of New Advent common stock.

Item 4.01 Change in Registrant’s Certifying Accountant.
On February 9, 2021, the Audit Committee of the Board 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”), AMCI’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 AMCI’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.
The reports of Marcum on AMCI’s financial statements as of and for the fiscal year ended December 31, 2019 and as of December 31, 2018 and for the period from June 18, 2018 (inception) to December 31, 2018 did not contain an adverse opinion or a disclaimer of opinion, and were not qualified or modified as to uncertainties, audit scope or accounting principles.
During AMCI’s fiscal year ended December 31, 2019 and the period from June 18, 2018 (inception) to December 31, 2018 and the subsequent interim period through February 4, 2021, there were no disagreements between AMCI and Marcum on any matter of accounting principles or practices, financial disclosure or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of AMCI, would have caused it to make reference to the subject matter of the disagreements in its reports on AMCI’s financial statements for such years.
During AMCI’s fiscal year ended December 31, 2019 and the period from June 18, 2018 (inception) to December 31, 2018 and the subsequent interim period through February 4, 2021, there were no “reportable events” (as defined in Item 304(a)(1)(v) of Regulation S-K under the Securities Exchange Act of 1934, as amended).
The Company has provided Marcum with a copy of the foregoing disclosures and has requested that Marcum furnish the Company with a letter addressed to the SEC stating whether it agrees with the statements made by the Company set forth above.

The sign-on bonuses are payable in two installments: (i) 50% on the first payroll date following the consummation of the Business Combination and (ii) 50% to be paid on the first payroll date following the one year anniversary of the consummation of the Business Combination, subject to the applicable executive’s employment through the relevant payment date.

The employment agreements provide that if an executive’s employment terminates without “cause” or by him for “good reason,” (as such terms are defined in the employment agreement), the executive will be entitled to (i) up to 12 months’ subsidized medical, dental and vision benefits continuation (18 months for Mr. Gregoriou) and (ii) payment of one times (two times for Messrs. Gregoriou and Hunter) the sum of such executive’s annual base salary and target bonus, payable over 12 months. If such termination of employment without “cause” or resignation for “good reason” occurs within 60 days prior to, or 12 months following, a “change in control” (as such term is defined in the Equity Incentive Plan described in further details in ”The Incentive Plan Proposal” section in the Proxy Statement/Prospectus), severance is enhanced and provides for (i) up to 18 months’ subsidized medical, dental and vision benefits continuation for all executives, (ii) two times (three times for Messrs. Gregoriou and Hunter) the sum of such executive’s annual base salary and target bonus, payable over 12 months, and (iii) the initial grant of stock options and restricted stock units issued pursuant to the Equity Incentive Plan, shall become fully vested, and such options will remain exercisable for a period of one year following such termination of employment. Moreover, if the acquirer in such “change in control” does not agree to assume or substitute for equivalent stock options, any unvested portion of the initial grant of stock options shall become fully vested and exercisable at the time of such transaction.
The employment agreements for Messrs. Gregoriou, Hunter, Kaskavelis, and Coffey each contain (i) a perpetual confidentiality covenant, (ii) an assignment of intellectual property covenant, (iii) a non-competition covenant for one year post-termination of employment (subject to, for Messrs. Gregoriou and Coffey, the Executive’s receipt of at least 50% of the Executive’s highest annualized base salary within the two (2)-year period preceding termination) for the entire year, (iv) a covenant not to solicit any of our customers, vendors, suppliers or other business partners during the eighteen (18)-month period following termination and (v) a covenant not to solicit any of our employees or independent contractors during the eighteen (18)-month period following termination.
Advent entered into transaction bonus letter agreements with each of Messrs. Gregoriou, De Castro, Coffey and Kaskavelis, which entitle each executive to receive a transaction bonus that is payable promptly following the Business Combination, contingent upon such executive’s continued employment through the consummation of the Business Combination and execution of a general release of claims. The transaction bonus entitlement for each executive is as follows: (i) for Mr. Gregoriou, $2,500,000, (ii) for each of Messrs. De Castro and Kaskavelis, $860,000 and (iii) for Mr. Coffey, $520,000.
