Restricted Stock Unit financial
"112,500 of Restricted Stock Units ("RSUs") granted under the Adagene Inc. 2021 Performance Incentive Plan"
A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.
American Depositary Shares (ADS) financial
"security_title": "American Depositary Shares (ADS)" for the reported open-market purchases"
American depositary shares (ADS) are a way for investors in the United States to buy shares of foreign companies without dealing with the complexities of international markets. They represent ownership in a foreign company's stock and are traded on U.S. exchanges, making it easier and more convenient for Americans to invest internationally. ADSs allow investors to diversify their portfolios with foreign companies while using familiar trading platforms.
Rule 10b5-1 regulatory
"aff_10b5_one is false, indicating the trades were not affirmed under a Rule 10b5-1 plan"
Rule 10b5-1 is a regulation that allows company insiders to buy or sell their shares at predetermined times, even if they have access to non-public information. It acts like setting a schedule in advance for transactions, helping prevent accusations of unfair trading. This rule provides a way for insiders to plan trades transparently, giving investors confidence that these transactions are not based on hidden information.
