Rule 10b5-1 trading plan regulatory
"were effected pursuant to a Rule 10b5-1 trading plan adopted"
A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.

Exercise or conversion of derivative security financial
"transaction_code_description": "Exercise or conversion of derivative security""
Redomiciliation regulatory
"The Redomiciliation had the effect of changing Wave-Singapore's domicile"
Redomiciliation is when a company legally changes its country of incorporation while keeping the same business and assets, like moving a house to a new neighborhood but keeping the same furniture. Investors care because the company then follows a different set of laws and tax rules, which can change shareholder rights, reporting standards, dividend treatment and the ease of trading the stock, potentially affecting risk and return.
Ordinary Shares financial
"underlying_security_title": "Ordinary Shares""
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.
