ADDITIONAL INFORMATION
AMCI Acquisition Corp., a Delaware corporation (“AMCI”), intends to
file with the U.S. Securities and Exchange Commission (the “SEC”) a registration statement on Form S-4 (as amended, the “Registration Statement”), which will include a preliminary proxy statement of AMCI, and a prospectus in connection with the proposed business combination transaction (the “Transaction”) involving AMCI and Advent Technologies Inc., a Delaware corporation (“Advent”). The definitive proxy statement and other
relevant documents will be mailed to shareholders of AMCI as of a record date to be established for voting on the Transaction. Stockholders of AMCI and other interested persons are advised to read, when available, the preliminary proxy statement,
and amendments thereto, and the definitive proxy statement in connection with AMCI’s solicitation of proxies for the special meetings to be held to approve the Transaction because these documents will contain important information about AMCI,
Advent and the Transaction. AMCI stockholders and other interest persons will also be able to obtain copies of the Registration Statement and the proxy statement/prospectus, without charge, once available, on the SEC’s website at www.sec.gov or by
directing a request to AMCI by contacting its Chief Executive Officer, William Hunter, c/o AMCI Acquisition Corp., 1501 Ligonier Street, Suite 370, Latrobe, PA
15650, at (724) 672-4319.
Participants in the Solicitation
AMCI and Advent and certain of their respective directors, executive officers, other
members of management and employees, under SEC rules, may be deemed to be participants in the solicitation of proxies from the stockholders of AMCI in favor of the approval of the Transaction. Stockholders of AMCI and other interested persons
may obtain more information regarding the names and interests in the proposed transaction of AMCI’s directors and officers in AMCI’s filings with the SEC, including AMCI’s annual report on form 10-K for the year-ended December 31, 2019, which was
filed with the SEC on March 27, 2020, as modified or supplemented by any Form 3 or Form 4 filed with the SEC since the date of such filing. Additional
information regarding the interests of such potential participants will also be included in the Registration Statement and other relevant documents when they are filed with the SEC. These documents can be obtained free of charge from the sources
indicated above.
Forward-Looking Statements
Certain statements made herein contain, and certain oral statements made by representatives of AMCI and Advent and their
respective affiliates, from time to time may contain, “forward-looking statements” within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995. AMCI’s and Advent’s actual results may differ from their
expectations, estimates and projections and consequently, you should not rely on these forward-looking statements as predictions of future events. Words such as “expect,” “estimate,” “project,” “budget,” “forecast,” “anticipate,” “intend,” “plan,”
“may,” “will,” “could,” “should,” “believes,” “predicts,” “potential,” “might” and “continues,” and similar expressions are intended to identify such forward-looking statements. These forward-looking statements include, without limitation, AMCI’s
and Advent’s expectations with respect to future performance and anticipated financial impacts of the Transaction, the satisfaction of the closing conditions to the Transaction and the timing of the completion of the Transaction. These
forward-looking statements involve significant risks and uncertainties that could cause actual results to differ materially from expected results. Most of these factors are outside of the control of AMCI or Advent and are difficult to predict.
Factors that may cause such differences include but are not limited to: (1) the occurrence of any event, change or other
circumstances that could give rise to the termination of the Merger Agreement (as defined below); (2 )the inability to complete the Transaction, including due to the failure to obtain approval of the stockholders of AMCI or Advent or other
conditions to closing in the Merger Agreement; (3) the inability to obtain or maintain the listing of AMCI’s common stock on Nasdaq following the Transaction, (4) the failure to meet the minimum cash requirements of the Merger Agreement due to AMCI
stockholder redemptions and the failure to obtain replacement financing; (5) the risk that the Transaction disrupts current plans and operations of Advent as a result of the announcement and consummation of the Transaction, (6) the failure to meet
projected development and production targets; (7) costs related to the proposed Transaction; (8) changes in applicable laws or regulations; (9) the ability of the combined company to meet its financial and strategic goals, due to, among other
things, competition, the ability of the combined company to pursue a growth strategy and manage growth profitability and hire and retain key employees; (10) the possibility that the combined company may be adversely affected by other economic,
business, and/or competitive factors; (11) the effect of the global COVID-19 pandemic on AMCI and Advent and their ability to consummate the Transaction or any of the foregoing risks; and (12) other risks and uncertainties described herein, as well
as those risks and uncertainties to be identified in the Registration Statement and proxy statement/prospectus (when available) relating to the Transaction, including those under “Risk Factors” therein, and in other filings with the SEC made by
AMCI. The foregoing list of factors is not exclusive. Readers are cautioned not to place undue reliance upon any forward-looking statements, which speak only as of the date made. Neither AMCI nor Advent undertakes or accepts any obligation or
undertaking to release publicly any updates or revisions to any forward-looking statements to reflect any change in its expectations or any change in events, conditions or circumstances on which any such statement is based, subject to applicable
law.

No Offer or Solicitation
This Current Report on Form 8-K and the exhibits hereto do not constitute a solicitation of a proxy, consent or authorization
with respect to any securities or in respect of the Transaction. This Current Report on Form 8-K shall also not constitute an offer to sell or the solicitation of an offer to buy any securities, nor shall there be any sale of securities in any
states or jurisdictions in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. No offering of securities shall be made except by means of a prospectus
meeting the requirements of Section 10 of the Securities Act of 1933, as amended,, or an exemption therefrom.

Entry into a Material Definitive Agreement.

First Amendment to Merger Agreement
On October 19, 2020, AMCI Acquisition Corp., a Delaware
corporation (“AMCI”), entered into a First Amendment to Agreement and Plan of Merger (the “First Amendment”) with the other parties to the Agreement and Plan of Merger, dated as of October 12, 2020 (the “Merger Agreement”),
by and among, AMCI, AMCI Merger Sub Corp., a Delaware corporation and a wholly-owned subsidiary of AMCI (“Merger Sub”), AMCI Sponsor LLC, a Delaware limited liability company, in its capacity as the Purchaser Representative thereunder (the “Purchaser Representative”), Advent Technologies Inc., a Delaware corporation (“Advent”),

amendment to AMCI’s warrant agreement (the “Warrant Amendment”) to cash out all outstanding warrants at $1.50 per warrant as was contemplated by the Merger
Agreement, and deleted all provisions of the Merger Agreement related to the Warrant Amendment, including without limitation the requirement to hold a meeting of AMCI warrantholders, that obtaining approval for and effecting the Warrant Amendment
is a condition to the closing under the Merger Agreement, and that the cash payment for the Warrant Amendment would be a deduction for the minimum cash condition for closing under the Merger Agreement.
The foregoing description of the First Amendment does not purport to be complete and is qualified in its entirety by reference
to the complete text of the First Amendment, a copy of which is filed with this Current Report on Form 8-K as Exhibit 2.2 and is incorporated herein by reference.

WHEREAS, Purchaser, Merger Sub, the Purchaser

NOW, THEREFORE, in consideration of the foregoing and the
respective representations, warranties, covenants and agreements set forth below and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and in accordance with the terms of the Merger Agreement,
the parties hereto, intending to be legally bound, do hereby agree as follows:
1. Amendments to Remove Warrant Amendment. The parties hereby agree
to amend the Original Agreement as follows:
a. Sections 3.5(c)
and 5.3(b) of the Original Agreement are hereby amended to delete each of the references to “Warrant Amendment” contained therein.
b. Section 5.13 of
the Original Agreement is hereby deleted in its entirety and replaced with the following:
(a) As
promptly as practicable after the date hereof, the Purchaser shall prepare with the reasonable assistance of the Company, and file with the SEC a registration statement on Form S-4 (as amended or supplemented from time to time, and including the
Proxy Statement contained therein, the “Registration Statement”) in connection with the registration under the Securities Act of the
Purchaser Common Stock to be issued under this Agreement as the Merger Consideration, which Registration Statement will also contain a proxy statement (as amended, the “Proxy Statement”) for the purpose of soliciting proxies from Purchaser stockholders for the matters to be acted upon at the Purchaser Special Meeting and providing the Public Stockholders an opportunity in
accordance with the Purchaser’s Organizational Documents and the IPO Prospectus to have their shares of Purchaser Common Stock redeemed (the “Redemption”)
in conjunction with the stockholder vote on the Purchaser Shareholder Approval Matters.
1
(b) The Proxy Statement shall
include proxy materials for the purpose of soliciting proxies from Purchaser stockholders to vote, at a special meeting of Purchaser stockholders to be called and held for such purpose (the “Purchaser Special Meeting”), in favor of resolutions approving (A) the adoption and approval of this Agreement and the transactions contemplated hereby or

(c) If on the date for which the
Purchaser Special Meeting is scheduled, Purchaser has not received proxies representing a sufficient number of shares to obtain the Required Purchaser Shareholder Approval, whether or not a quorum is present, Purchaser may make one or more
successive postponements or adjournments of the Purchaser Special Meeting. Purchaser shall use its reasonable best efforts to solicit from the Purchaser stockholders proxies in favor of the Purchaser Shareholder Approval Matters prior to such
Purchaser Special Meeting, and to take all other reasonable actions necessary or advisable to secure the Required Purchaser Shareholder Approval.
(d) [RESERVED]

Registration Statement and any amendment or supplement thereto prior to filing the same with the SEC, and Purchaser shall consider any such comments in good faith. The Company shall provide Purchaser with such information concerning the Target

amendments or supplements thereto, which information provided by the Company shall be true and correct and not contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements made, in

best efforts to satisfy the requirements of the Securities Act, the Exchange Act and other applicable Laws in connection with the Registration Statement, the Purchaser Special Meeting and the Redemption. Each of Purchaser and the Company shall,
and shall cause each of its Subsidiaries to, make their respective directors, officers and employees, upon reasonable advance notice, available to the Company, Purchaser and, after the Closing, the Purchaser Representative, and their respective
Representatives in connection with the drafting of the public filings with respect to the transactions contemplated by this Agreement, including the Registration Statement, and responding in a timely manner to comments from the SEC. Each Party
shall promptly correct any information provided by it for use in the Registration Statement (and other related materials) if and to the extent that such information is determined to have become false or misleading in any material respect or as
otherwise required by applicable Laws. Purchaser shall amend or supplement the Registration Statement and cause the Registration Statement, as so amended or supplemented, to be filed with the SEC and to be disseminated to Purchaser stockholders
as and to the extent required by applicable Laws and subject to the terms and conditions of this Agreement and the Purchaser’s Organizational Documents.
2
(g) Purchaser, with the assistance
of the other Parties, shall promptly respond to any SEC comments on the Registration Statement and shall otherwise use its commercially reasonable efforts to cause the Registration Statement to “clear” comments from the SEC and become effective.

Statement, the Purchaser Special Meeting, and the Redemption promptly after the receipt of such comments and shall give the Company a reasonable opportunity under the circumstances to review and comment on any proposed written or material oral
responses to such comments (and Purchaser shall consider any such comments by the Company in good faith).

Amendment, all of the terms and provisions in the Original Agreement and the Ancillary Documents are and shall remain unchanged and in full force and effect, on the terms and subject to the conditions set forth therein. This First Amendment does
not constitute, directly or by implication, an amendment or waiver of any provision of the Original Agreement or any Ancillary Document, or any other right, remedy, power or privilege of any party, except as expressly set forth herein. Any
reference to the Merger Agreement in the Merger Agreement or any other agreement, document, instrument or certificate entered into or issued in connection therewith shall hereinafter mean the Original Agreement, as amended by this First Amendment
(or as the Merger Agreement may be further amended or modified after the date hereof in accordance with the terms thereof). The Original Agreement, as amended by this First Amendment, and the documents or instruments attached hereto or thereto
or referenced herein or therein, constitutes the entire agreement between the parties with respect to the subject matter of the Merger Agreement, and supersedes all prior agreements and understandings, both oral and written, between the parties
with respect to its subject matter. If any provision of the Original Agreement is materially different from or inconsistent with any provision of this First Amendment, the provision of this First Amendment shall control, and the provision of the
Original Agreement shall, to the extent of such difference or inconsistency, be disregarded. This First Amendment shall be interpreted, construed, governed and enforced in a manner consistent with the Original Agreement, and, without limiting
the foregoing, Sections 9.2 through 9.10, 9.12 and 9.13 of the Original Agreement are hereby incorporated herein by reference as if fully set forth herein, and such provisions apply to this First Amendment as if all references to the “Agreement”
contained therein were instead references to this First Amendment.

2 This presentation has been prepared by Advent Technologies Inc. (“Advent”) and AMCI Acquisition
Corp. (“AMCI”) to assist interested parties in making their own evaluation with respect to the proposed business combination between Advent and AMCI and for no other purpose. The data contained herein is derived from various internal and
external sources. Please refer to the merger agreement for the business combination between Advent and AMCI and the filings by AMCI with the United States Securities and Exchange Commission (“SEC”) for the full terms of the transaction. While
the information contained in this presentation has been prepared in good faith, neither Advent nor AMCI, nor any of their respective shareholders, directors, officers, agents, employees, affiliates, representatives or advisors, makes any
representations or warranties (express or implied) as to, or in relation to, the fairness, accuracy, reliability or completeness of the information in this presentation, and liability therefor is expressly disclaimed. Accordingly, neither
Advent nor AMCI, nor any of their respective shareholders, directors, officers, agents, employees, affiliates, representatives or advisors, takes any responsibility for, or will accept any liability, whether direct or indirect, express or
implied, contractual, tortious, statutory or otherwise, with respect to the accuracy or completeness of the information in this presentation or for any of the opinions, estimates, projections, forecasts, targets, or prospects contained in
this presentation or for any errors, omissions or misstatements or for any loss, howsoever arising from this presentation. The information, opinions, estimates, projections, forecasts, targets, or prospects contained in this presentation are
provided as at the date of this presentation and are subject to change without notice.This presentation contains financial information prepared in accordance with U.S. generally accepting accounting principles (“GAAP”) that have been
extracted without material adjustment from audited GAAP financial statements and/or extracted or derived from unaudited accounting records that have been used to prepare GAAP financial statements. This presentation also contains certain
non-GAAP financial measures which have not been and will not be audited. These non-GAAP financial measures are not recognized measures of financial performance or liquidity under GAAP, but are measures used by Advent’s management to monitor
the underlying performance of Advent’s business and operations. These non-GAAP measures may not be indicative of Advent’s historical operating results nor are such measures meant to be predicative of future results. These measures and ratios
may not be comparable to those used by other companies under the same or similar names. As such, undue reliance should not be placed on these non-GAAP financial measures. Certain financial information contained herein is unaudited and is
based on internal records and/or estimates. This presentation contains certain forward-looking information which may not be included in future public filings or investor guidance. The inclusion of financial information or metrics in this
presentation should not be construed as a commitment by Advent or AMCI to provide guidance on such information in the future. The balance sheet and income statement data contained herein is currently subject to audit in accordance with the
rules of the Public Company Accounting Oversight Board (“PCAOB”) and may be updated or modified in the final audited financial statements included in the proxy statement with respect to the meeting of AMCI stockholders related to AMCI’s
business combination with Advent and the related registration statement on Form S-4.The information contained in this presentation is the property of Advent and AMCI. This presentation may not be copied, published, reproduced or distributed
in whole or in part at any time without the prior written consent of Advent and AMCI. The trademarks and trademark symbols used herein are the properties of their respective owners.This presentation does not constitute investment, legal,
accounting, regulatory, taxation or other advice, and neither this presentation nor the information in this presentation takes into account the recipient’s investment objectives, or the recipient’s legal, accounting, regulatory, taxation or
financial situation or particular needs. In particular, any estimates, projections, forecasts, targets, prospects or opinions contained in this presentation necessarily involve significant elements of subjective judgment, analysis and
assumption are based upon the reasonable judgment of Advent and AMCI, subject to change without notice, and each recipient should satisfy itself in relation to such matters. This presentation, the information contained in this presentation or
any related oral presentation is for informational purposes only and does not constitute, or form part of, any offer, invitation to sell or issue, or any solicitation of any offer to subscribe for, purchase or otherwise acquire any securities
in Advent or AMCI or their respective affiliates, nor shall this presentation, or the fact of its communication, form the basis of, or be relied upon in connection with, or act as any inducement to enter into any contract or commitment
whatsoever with respect to such securities. This presentation and the information in this presentation are not directed to, or intended for distribution to or use by, any person or entity that is a citizen or resident located in any locality,
state, country or other jurisdiction where such distribution, publication, availability or use would be contrary to law or regulation or which would require registration of licensing within such jurisdiction. This presentation contains
financial forecasts with respect to Advent’s estimated future performance. These forecasts have been prepared solely by Advent and have not been diligenced by AMCI. Neither AMCI’s independent auditors nor the independent auditors of Advent
audited, reviewed, compiled or performed any procedures with respect to the projections for the purpose of their inclusion in this Investor Presentation and, accordingly, neither of them expressed an opinion or provided any other form of
assurance with respect thereto for the purpose of this presentation. None of these forecasts were prepared with a view toward compliance with the published guidelines of the SEC, PCAOB, GAAP or the guidelines established by the American
Institute of Certified Public Accountants for preparation and presentation of financial forecasts. These projections should not be relied upon as being necessarily indicative of future results. In this presentation certain of the
above-mentioned projected financial information has been included (in each case, with an indication that the information is an estimate and is subject to the qualifications presented herein) for purposes of providing comparisons with
historical data. The assumptions and estimates underlying the prospective financial information are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could
cause actual results to differ materially from those contained in the prospective financial information. Accordingly, there can be no assurance that the prospective results are indicative of the future performance of Advent or AMCI or that
actual results will not differ materially from those presented in the prospective financial information. Inclusion of the prospective financial information in this Investor Presentation should not be regarded as a representation by any person
that the results contained in the prospective financial information will be achieved. The financial forecasts reflect assumptions that are subject to change, and there can be no assurance that AMCI’s or Advent’s financial condition or results
of operations will be consistent with those set forth in such analyses and forecasts. Disclaimer

3 This presentation contains “forward-looking statements” within the meaning of applicable securities
laws, including statements with respect to Advent’s strategies, future opportunities and growth prospects, Advent’s financial statements, as well as other information and statements that are not historical fact. These forward-looking
statements regarding future events and the future results of Advent and AMCI are based on current expectations, estimates, forecasts, and projections about the industry in which Advent operates, as well as the beliefs and assumptions of
Advent’s management. These forward-looking statements are only predictions and are subject to known and unknown risks, uncertainties, assumptions and other factors beyond Advent’s or AMCI’s control that are difficult to predict because they
