Rule 144 regulatory

"sales required by paragraph (e) of Rule 144 to be aggregated"

Rule 144 is a U.S. securities regulation that sets conditions under which restricted or insider-held shares can be legally resold to the public, such as required holding periods, availability of public information, limits on how much can be sold at once, and certain filing requirements. For investors it matters because it determines when previously locked-up shares can enter the market — like a release valve that can increase supply, affect share price, and signal insider intent.

Incentive Compensation Stock Grant financial

"Ordinary Shares | 09/07/2018 | Incentive Compensation Stock Grant"

Ordinary Shares financial

"Ordinary Shares | 12/07/2018 | Incentive Compensation Stock Grant"

Ordinary shares are a type of ownership stake in a company, giving shareholders a right to participate in the company’s profits and decision-making through voting. They are similar to owning a piece of a business, and their value can rise or fall based on the company's performance. Investors buy ordinary shares to potentially earn dividends and benefit from the company's growth over time.
