WORLD BLOCKCHAIN CORP. ANNOUNCES TICKER SYMBOL CHANGE FROM "CK" TO "WBG" ON THE CANADIAN SECURITIES EXCHANGE

World Blockchain Corp.'s stock ticker symbol on the Canadian Securities Exchange will change from CK to WBG, effective at the market open on Tuesday, Nov. 18, 2025.

As a result of this change, WBG will now be the ticker symbol for the company's common shares listed on the CSE. This update reflects improved and consistent brand alignment between the company and its publicly traded equity.

No action is required by World Blockchain's shareholders in connection with the ticker symbol change. The Cusip number for World Blockchain's common shares remains unchanged, and no steps need to be taken with respect to previously issued share certificates, as these are not affected by the symbol change.

The company will continue evolving strategic direction and global focus within the blockchain sector.
