American Depositary Shares ("ADSs") financial

"based on the trading price of the Issuer's American Depositary Shares ("ADSs")."

American Depositary Shares (ADSs) are U.S.-listed certificates issued by a bank that represent ownership of a specified number of a foreign company’s ordinary shares, letting U.S. investors buy and sell those interests in U.S. dollars on American markets. They matter because they make investing in overseas companies as easy as buying a domestic stock—streamlining currency, settlement, and recordkeeping—while still exposing investors to foreign-market risks like exchange rates and local regulations.

fair market value financial

"exercise price per share is equal to the fair market value per Ordinary Share"

The price a willing buyer and a willing seller would agree on for an asset or security when neither is under pressure and both have access to the same information. Think of it as the market’s neutral estimate of what something is worth, like the price two neighbors would settle on for a car after comparing similar listings. Investors care because fair market value guides buying and selling decisions, tax reporting, portfolio valuation, and how accurately company assets are reflected in financial statements.

vest in equal monthly installments financial

"The shares vest in equal monthly installments over the 12 months"

Ordinary Shares financial

"The Ordinary Shares of the Issuer may be represented by ADSs."

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.
