# Why Is Advent Technologies Stock (ADN) Down 55% Today?

> Advent Technologies stock (ADN) is down 55% due to a decision to delist it for non-compliance with Nasdaq Listing Rule 5550(b)(1), which requires a minimum stockholders' equity of $2.5 million. A trading suspension will start on Thursday, but shares will continue trading on the OTC market under the same ticker. The stock fell 57.93% in pre-market trading and has decreased 45.8% year-to-date, despite a 52.25% increase over the past year. Heavy trading activity was noted with over 636,000 shares exchanged today.

The decision to delist Advent Technologies stock was due to a lack of compliance. The company has broken Nasdaq Listing Rule 5550(b)(1), which requires stockholders' equity of at least $2.5 million. This will result in the delisting of ADN stock, as well as its warrants to purchase one share of the stock at an exercise price of $345 each. The SEC filing noted that a trading suspension will go into effect on Thursday.

While Advent Technologies is being delisted, investors will still be able to buy its stock afterward. The company expects its shares to start trading on the OTC market. The shares will still use the same ADN stock ticker and warrants will trade under the ADNWW symbol.
