"did not exceed 25% of the average daily trading volume of the Company’s shares"

The average daily trading volume is the typical number of shares or units of a security that change hands each trading day, calculated over a set period. It tells investors how active a market is—like average traffic on a road—so higher volume usually means easier, faster trades and smaller price swings when buying or selling, while low volume can make orders harder to fill and cause bigger price moves.
