Advent Technologies faces potential Nasdaq delisting, plans to appeal decision

Advent Technologies Holdings, Inc. (NASDAQ:ADN) announced it received a delisting determination from the Nasdaq Stock Market after failing to satisfy the minimum stockholders’ equity requirement of $2.5 million, according to a press release statement filed with the Securities and Exchange Commission.

The company disclosed that, as previously reported, it had been notified by Nasdaq on October 18, 2024, of non-compliance with Listing Rule 5550(b)(1). Nasdaq had granted Advent Technologies an extension to regain compliance by April 16, 2025. The company stated that, following recent developments and the resolution of certain claims, it believed it had regained compliance as of April 15, 2025. On April 16, 2025, Nasdaq staff advised the company it was in conditional compliance, contingent on reflecting the required equity adjustment in its quarterly report for the period ending June 30, 2025. Despite these challenges, the stock has shown remarkable resilience, posting a 28.7% return over the past week.

Advent Technologies filed its quarterly report on August 12, 2025, but was unable to show a sufficient adjustment to stockholders’ equity. As a result, the company received a delisting notice from Nasdaq staff on Monday, stating that it had not met the conditions to regain compliance. According to the notice, unless Advent Technologies requests a hearing panel appeal by August 25, 2025, its securities will be delisted from Nasdaq on August 27, 2025.

The company stated it intends to appeal Nasdaq’s determination to a hearing panel, which would stay any further delisting actions during the appeal process or any extension granted by the panel. While the appeal is pending, Advent Technologies’ common stock, par value $0.0001 per share, will continue to trade on Nasdaq under the symbol ADN, and its warrants will continue to trade under the symbol ADNWW.

This information is based on a press release statement filed with the SEC.
