The Company is exploring the benefits of a dual listing of its common shares on a major U.S. exchange, including the New York Stock Exchange, for a potential listing in the first half of 2026. The Company believes a U.S. listing could lead to increased interest by a wider audience of potential investors and result in increased marketability and trading liquidity. The principal reason for the Consolidation is to raise the per share trading price of the common shares in order to better comply with minimum trading price requirements of such exchanges.

Subject to approval by the Toronto Stock Exchange, OceanaGold expects the Consolidation to be effective on or around June 23, 2025, and intends to issue a detailed press release to provide a further update and final details on the Consolidation.

Appointment of Auditor

A resolution appointing PricewaterhouseCoopers LLP (PWC Canada) as the auditor of the Company for the ensuing year and authorizing the board of the Company to fix their remuneration was passed.
