material non-public information regulatory
"not aware of any material non-public information regarding the Company"
Material non-public information is important news about a company that hasn't been shared with the public yet, like a secret that could affect its stock price. Using this inside information to buy or sell stocks is unfair and illegal because it gives someone an unfair advantage over others who don’t have the same info.
trading volume financial
"recent unusual trading activity in the price and trading volume of its Class A ordinary shares"
Trading volume is the total number of shares, units, or contracts that are bought and sold within a specific period. It indicates how active or busy a market is, much like how many customers visit a store in a day. Higher trading volume generally suggests greater interest and can influence the price movements of a financial asset.
Good Manufacturing Practices for Veterinary Drugs medical
"operating in accordance with Good Manufacturing Practices for Veterinary Drugs"
Good manufacturing practices for veterinary drugs are regulatory standards that set how animal medicines must be designed, made, tested and documented to ensure consistent quality, safety and traceability. They cover facilities, equipment, staff training, production procedures and record-keeping—think of them as a strict recipe and kitchen hygiene rules that make every batch reliable. For investors, these rules matter because compliance affects product approvals, market access, liability risk and company reputation.
forward-looking statements regulatory
"This announcement contains statements that may constitute “forward-looking” statements"
Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.
veterinary vaccines medical
"research, development, manufacturing, and sales of veterinary vaccines"
