Key Terms

Form 3, Class A Ordinary Share, indirect ownership

3 terms

Form 3 regulatory

"Form 3 data reflects a holding entry"

Form 3 is the initial public filing that officers, directors and large shareholders must submit to report their ownership of a company’s securities when they become insiders. It acts like an opening inventory sheet that gives investors a starting point to see who holds significant stakes and to spot later trades or potential conflicts of interest, helping assess insider confidence and transparency.

Class A Ordinary Share financial

"3,850 Class A Ordinary Shares are indirectly owned"

A Class A ordinary share is a type of common stock a company issues that carries a specific set of rights—most often particular voting power, dividend terms, or transfer rules—distinct from other share classes. For investors it matters because those rights affect control over company decisions, how income is paid out, and how easy shares are to buy or sell; think of it like a tiered ticket that gives different access and influence at the same event.
