Osisko Development Corp. has officially changed its name to Osisko Gold Group Inc. The company will begin trading under the new ticker symbol OGG on both the TSX Venture Exchange and the New York Stock Exchange. This change becomes effective at the market open on July 20, 2026.

The rebranding reflects the company's strategic focus on gold and precious metals assets. This shift specifically highlights the advancement of the Cariboo Gold Project in British Columbia. Shareholders previously approved the name change to align with the company's evolution toward North American gold projects.

Osisko Gold Group will update its CUSIP and ISIN numbers for all common shares and warrants. The company does not anticipate any interruptions to trading activities during this transition.
