American Depositary Shares financial
"Ordinary Shares are represented by American Depositary Shares ("ADSs")."
American depositary shares (ADSs) are a way for investors in the United States to buy shares of foreign companies without dealing with international markets directly. They represent ownership in a foreign company's stock and are traded on U.S. stock exchanges, making it easier for American investors to buy, sell, and own parts of companies from around the world.
ADSs financial
"Ordinary Shares are represented by American Depositary Shares ("ADSs")."
ordinary warrants financial
"The ADSs and accompanying ordinary warrants ("Warrants") were issued"
A warrant that gives its holder the right to buy ordinary shares (common stock) at a fixed price for a set period. Think of it as a coupon that lets an investor purchase a share later at a predetermined price; if the market price rises above that price the coupon is valuable, otherwise it may expire worthless. Investors care because exercising warrants can amplify gains but also dilute existing shareholders by increasing the number of shares outstanding.
beneficial ownership cap financial
"The Warrants were exercisable immediately upon issuance, subject to a beneficial ownership cap."
A beneficial ownership cap is a rule that limits how much of a company a single investor or related group can effectively control, even if legal ownership could be higher. Think of it as a speed limit for ownership that prevents any one party from accumulating a controlling stake; it matters to investors because it affects takeover risk, voting power, dilution, and potential returns by shaping who can influence corporate decisions.
combined purchase price financial
"were issued at a combined purchase price of $4.88."
