Exhibit 99.1
UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION
Defined terms included below have the same meaning as terms defined and included elsewhere in this Current Report on Form 8-K and, if not defined in the Form 8-K, the Proxy Statement / Prospectus.
On October 12, 2020 AMCI, Merger Sub and Advent, entered into the original Merger Agreement, pursuant to which Merger Sub merged with and into the Advent, effective as of February 4 2021, for an aggregate value equal to $250,000,000 minus the amount of the Closing Net Indebtedness, with each share of New Advent common stock valued for such purposes at $10.00. Advent survived the Business Combination as a wholly owned subsidiary of AMCI, and AMCI was renamed to “Advent Technologies Holdings, Inc.”
References to Merger Agreement are construed to refer to the Merger Agreement noted above as amended on October 19, 2020 to remove the requirement for AMCI to cash-out all outstanding Warrants and amended again on December 31, 2020 to (a) reduce the size of the board of directors of the Combined Entity following the Business Combination from nine members to seven members, (b) increase the amount of aggregate cash bonus payments to be made in connection with Closing from $2,955,208 to $4,995,202, and (c) amend certain terms of the form of employment agreement of Christos Kaskavelis.
The following unaudited pro forma condensed combined financial statements of AMCI present the combination of the financial information of AMCI and Advent adjusted to give effect to the Business Combination. The following unaudited pro forma condensed combined financial information has been prepared in accordance with Article 11 of Regulation S-X.
The unaudited pro forma condensed combined balance sheet as of September 30, 2020 combines the historical balance sheet of AMCI and the historical balance sheet of Advent on a pro forma basis as if the Business Combination and related transactions, summarized below, had been consummated on September 30, 2020. The unaudited pro forma condensed combined statements of operations for the nine months ended September 30, 2020 and the year ended December 31, 2019 combine the historical statements of operations of AMCI and Advent for such periods on a pro forma basis as if the Business Combination and related transactions, summarized below, had been consummated on January 1, 2019, the beginning of the earliest period presented:

| • | the merger of Advent with and into Merger Sub, a wholly owned subsidiary of AMCI, with Advent surviving the merger as a wholly owned subsidiary of AMCI;
| • | the redemption of 5,864,053 AMCI’s Class A common stock at a redemption price of $60 million, as a result of the voting for the amendment and extension of the certificate of incorporation of AMCI;
| • | the redemption of 1,606 shares of AMCI’s Class A common stock at a price of approximately $10.30 per share, for an aggregate of $16,536, in connection with the consummation of the Business Combination;
| • | the issuance and sale of 6,500,000 shares of AMCI’s Class A common stock at a purchase price of $10.00 per share, for an aggregate of $65 million, in the PIPE pursuant to the Subscription Agreement; and
| • | the issuance and sale of 400,000 Working Capital Warrants at a price of $1.00 per Warrant.

The historical financial statements have been adjusted in the unaudited pro forma condensed combined financial statements to give pro forma effect to events that are: (i) directly attributable to the Business Combination; (ii) factually supportable; and (iii) with respect to the statement of operations, expected to have a continuing impact on AMCI’s results following the completion of the Business Combination.

The unaudited pro forma condensed combined financial statements have been developed from and should be read in conjunction with:

| • | the accompanying notes to the unaudited pro forma condensed combined financial statements;
| • | the (i) historical audited financial statements of AMCI as of and for the year ended December 31, 2019 and (ii) historical condensed unaudited financial statements of AMCI as of and for the nine month period ended September 30, 2020 and the related notes, in each case, incorporated by reference into this Current Report on Form 8-K;
| • | the (i) historical audited consolidated financial statements of Advent as of and for the year ended December 31, 2019 and (ii) historical condensed unaudited consolidated financial statements of Advent as of and for the nine month period ended September 30, 2020 and the related notes, in each case, incorporated by reference into this Current Report on Form 8-K; and
| • | other information relating to AMCI and Advent contained in the Proxy Statement / Prospectus, including the merger agreement and the description of certain terms thereof set forth under “The Business Combination”.

After giving effect to the redemption of the Class A public shares, Advent’s shareholders hold 25,033,398 shares of AMCI common stock immediately after the Closing, which approximates a 54% ownership level.

Stockholder | ​ | ​ |
| ​ | ​ | % | ​ | ​ | No. shares
Advent | ​ | ​ | 54.3 |  |  | 25,033,398
Public | ​ | ​ | 19.6 |  |  | 9,059,530
Sponsor | ​ | ​ | 5.4 |  |  | 2,474,009
AMCI’s executive management |  |  | 1.1% |  |  | 485,000
Other AMCI holders | ​ | ​ | 5.5 |  |  | 2,554,010
PIPE Investors | ​ | ​ | 14.1 |  |  | 6,500,000
Total | ​ | ​ | 100% |  |  | 46,105,947

The foregoing ownership percentages with respect to the Combined Entity following the Business Combination reflect that (i) there are no adjustments for the outstanding public, private placement or working capital warrants issued by AMCI; (ii) Advent’s Closing Net Indebtedness was ($334,359.63), computed as debt less cash and cash equivalents, immediately prior to the Closing; (iii) no awards were issued under the Equity Incentive Plan, and (iv) AMCI did not engage in any kind of equity financing prior to the Closing, other than the $65 million PIPE investment described above.
Notwithstanding the legal form of the Business Combination pursuant to the Merger Agreement, the Business Combination is accounted for as a reverse recapitalization in accordance with U.S. GAAP. Under this method of accounting, AMCI is treated as the acquired company and Advent is treated as the acquirer for financial statement reporting purposes. Advent has been determined to be the accounting acquirer based on evaluation of the following facts and circumstances:

| • | Advent’s existing stockholders have the greatest voting interest in the Combined Entity with 54% voting interest;
| • | the largest individual minority stockholder of the Combined Entity is an existing stockholder of Advent;
| • | Advent’s appointed directors represent five out of seven board seats for the Combined Entity’s board of directors;
| • | Advent selects all senior management (executives) of Combined Entity;
| • | Advent’s senior management comprise the majority of the senior management of the Combined Entity; and
| • | Advent operations are the only continuing operations of the Combined Entity.

Assumptions and estimates underlying the unaudited pro forma adjustments set forth in the unaudited pro forma condensed combined financial statements are described in the accompanying notes. The unaudited pro forma condensed combined financial statements have been presented for illustrative purposes only and are not necessarily indicative of the operating results and financial position that would have been achieved had the merger occurred on the dates indicated. Further, the unaudited pro forma condensed combined financial statements do not purport to project the future operating results or financial position of AMCI following the completion of the merger. The unaudited pro forma adjustments represent AMCI’s management’s estimates based on information available as of the date of these unaudited pro forma condensed combined financial statements and are subject to change as additional information becomes available and analyses are performed.

Notes to Unaudited Pro Forma Condensed Combined Financial Statements

1. | Basis of Presentation

The Business Combination is accounted for as a reverse recapitalization, with no goodwill or other intangible assets recorded, in accordance with GAAP. Under this method of accounting, AMCI is treated as the “acquired” company for financial reporting purposes. Accordingly, for accounting purposes, the Business Combination is treated as the equivalent of Advent Technologies Inc. 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 unaudited pro forma condensed combined balance sheet as of September 30, 2020 gives pro forma effect to the Business Combination as if it had been consummated on September 30, 2020. The unaudited pro forma condensed combined statement of operations for the year ended December 31, 2019 and for the nine months ended September 30, 2020 give pro forma effect to the Business Combination as if it had been consummated on January 1, 2019.
The unaudited pro forma condensed combined balance sheet as of September 30, 2020 has been prepared using, and should be read in conjunction with, the following:

| • | AMCI’s condensed unaudited balance sheet as of September 30, 2020 and the related notes incorporated by reference into this Current Report on Form 8-K; and
| • | Advent’s unaudited condensed consolidated balance sheet as of September 30, 2020 and the related notes incorporated by reference into this Current Report on Form 8-K.

The unaudited pro forma condensed combined statement of operations for the year ended December 31, 2019 has been prepared using, and should be read in conjunction with, the following:

| • | AMCI’s audited consolidated statement of operations for the year ended December 31, 2019 and the related notes included elsewhere in this proxy statement/ prospectus/ registration statement; and
| • | Advent’s audited statement of operations for the year ended December 31, 2019 and the related notes included elsewhere in this proxy statement/ prospectus/ registration statement.

The unaudited pro forma condensed combined statement of operations for the year ended December 31, 2019 has been prepared using, and should be read in conjunction with, the following:

| • | Advent’s unaudited interim condensed consolidated statement of operations for the nine months ended September 30, 2020 and the related notes incorporated by reference into this Current Report on Form 8-K.

Management has made significant estimates and assumptions in its determination of the pro forma adjustments. As the unaudited pro forma condensed combined financial information has been prepared based on these preliminary estimates, the final amounts recorded may differ materially from the information presented.
The pro forma adjustments reflecting the consummation of the Merger Agreement are based on certain currently available information and certain assumptions and methodologies that Management believes are reasonable under the circumstances. The unaudited condensed pro forma adjustments, which are described in the accompanying notes, may be revised as additional information becomes available and is evaluated. Therefore, it is likely that the actual adjustments will differ from the pro forma adjustments and it is possible the difference may be material. Management believes that its assumptions and methodologies provide a reasonable basis for presenting all of the significant effects of the merger based on information available to Management at the time and that the pro forma adjustments give appropriate effect to those assumptions and are properly applied in the unaudited pro forma condensed combined financial information.
The unaudited pro forma condensed combined financial information is not necessarily indicative of what the actual results of operations and financial position would have been had the business combination taken place on the dates indicated, nor are they indicative of the future consolidated results of operations or financial position of the post-combination company. They should be read in conjunction with the historical financial statements and notes thereto of AMCI and Advent.

2. | Accounting Policies and Reclassifications

Management will perform a comprehensive review of the two entities’ accounting policies. As a result of the review, management may identify differences between the accounting policies of the two entities which, when conformed, could have a material impact on the financial statements of the post-combination company. Based on its initial analysis, management did not identify any differences that would have a material impact on the unaudited pro forma condensed combined financial information. As a result, the unaudited pro forma condensed combined financial information does not assume any differences in accounting policies.

3. | Adjustments to Unaudited Pro Forma Condensed Combined Financial Information

The unaudited pro forma condensed combined financial information has been prepared to illustrate the effect of the Business Combination and has been prepared for informational purposes only. The historical financial statements have been adjusted in the unaudited pro forma condensed combined financial information to give pro forma effect to events that are (1) directly attributable to the merger, (2) factually supportable, and (3) with respect to the statements of operations, expected to have a continuing impact on the results of the post-combination company. AMCI and Advent Technologies Inc. have not had any historical relationship prior to the merger. Accordingly, no pro forma adjustments were required to eliminate activities between the companies.
The pro forma combined provision for income taxes does not necessarily reflect the amounts that would have resulted had the post-combination company filed consolidated income tax returns during the periods presented.

4. | Loss per Share

Represents the net loss per share calculated using the historical weighted average shares outstanding, and the issuance of additional shares in connection with the Business Combination, assuming the shares were outstanding since January 1, 2019. As the merger agreement is being reflected as if they had occurred at the beginning of the periods presented, the calculation of weighted average shares outstanding for basic and diluted net loss per share assumes that the shares issuable relating to the merger have been outstanding for the entire periods presented..

| ​ | ​ | Year Ended December 31, 2019 | ​ | ​ | ​ | ​ | ​ | ​ | Nine Months Ended September 30, 2020 |
Pro forma net loss | ​ | ​ | $(2,239,811) | ​ | ​ | ​ | ​ | ​ | ​ | $(3,524,610) |

Net loss per share—basic and diluted(1) | ​ | ​ | $(0.049) | ​ | ​ | ​ | ​ | ​ | ​ | $(0.076) |
(1) | For the purposes of applying the if converted method for calculating diluted earnings per share, it was assumed that all outstanding warrants sold in the initial public offering and the private placement are converted to Class A common stock of AMCI. However, since this results in anti-dilution, the effect of such exchange was not included in calculation of diluted loss per share.
