beneficial ownership regulatory

"aggregate number of ordinary shares beneficially owned by the Reporting Persons"

Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.

open-market transactions financial

"sold an aggregate of 111,050 Ordinary Shares in open-market transactions"

Open-market transactions are purchases or sales of a company’s securities that take place on public exchanges rather than through private agreements. They matter to investors because these trades change the number of shares available, can move the stock price, and often signal management’s view of the company’s value—like a store restocking or clearing shelves, altering supply and the price shoppers see.

sole voting and dispositive power regulatory

"Each of the Reporting Person has sole voting and dispositive power"

aggregate consideration financial

"for an aggregate consideration of approximately US$335,000"
