Employee Restricted Stock Awards Rules financial

"Common Shares vested on September 1, 2026 in accordance with the issuer's Employee Restricted Stock Awards Rules"

American Depositary Share financial

"Each American Depositary Share represents five (5) Common Shares"

An American Depositary Share (ADS) is a U.S.-listed certificate that represents a specified number of shares in a foreign company, held by a custodian bank; it works like a receipt that allows U.S. investors to buy and trade foreign equity on American exchanges without dealing with another country’s markets. Investors care because ADSs make foreign stocks easier to access, improve liquidity and settlement in dollars, and can affect dividend payments, voting rights and regulatory oversight compared with buying the underlying foreign shares directly.

"Common Shares purchased and held under the issuer's Employee Stock Purchase Plan ("ESPP")"
