Advent is a world-leading company in the development of the HT-PEM technology (with more than 150 patents issued, pending, or licensed worldwide). The HT-PEM fuel cell technology developed by Advent enables off-grid power systems to produce clean power from various green fuels (hydrogen, methanol, bio and eMethanol, and renewable natural gas) and to function with higher efficiency at extreme ambient temperatures and in general extreme environmental conditions (humidity, air pollution). Advent’s main operations focus on developing and manufacturing the Membrane Electrode Assembly (MEA), which is the core electrochemical element and the most critical component of the fuel cell. The MEA largely determines lifetime, power density, efficiency, and overall cost of installation and operation for all applications. Advent is working with world-leading market-leading OEMs with the goal of bringing to the market complete fuel cell systems for a range of applications in the stationary power markets (backup, off-grid, and portable power) and the heavy-duty mobility markets (automotive, aviation, marine).</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Advent has its headquarters in Livermore, California, and the Company has MEA and fuel cell product development facilities in Livermore, California and Patras, Greece. Previously, the Company’s headquarters were located in Boston, Massachusetts. During 2023, the Company decided to consolidate certain of its German operations with its operations in Greece. During June 2024, the Company closed its facilities in Boston, MA, and no longer maintains its facilities in Denmark and the Philippines due to the bankruptcy of Advent Technologies A/S in July 2024.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">On February 4, 2021 (“Closing Date”), AMCI Acquisition Corp.

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.

Because of the uncertainty in securing additional funding, delays in growth of revenue, failure to materialize cost-cutting efforts and the insufficient amount of cash and cash equivalents as of the consolidated financial statement filing date, management has concluded that substantial doubt exists with respect to the Company’s ability to continue as a going concern for one year from the date the unaudited condensed consolidated financial statements are issued.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0"> </p>
