OceanaGold Announces Effective Date of Share Consolidation in Connection with Proposed U.S. Listing

VANCOUVER, BC, June 19, 2025 /PRNewswire/ - OceanaGold Corporation (TSX: OGC) (OTCQX: OCANF) ("OceanaGold" or the "Company") announces the consolidation of its common shares on the basis of three (3) pre-consolidation common shares for one (1) post-consolidation common share (the "Consolidation") will take effect as of Monday, June 23, 2025 (the "Effective Date").

The shareholders of OceanaGold approved the Consolidation at the Annual General and Special Meeting held on June 4, 2025.

The Company is considering a dual listing of its common shares on a major U.S. exchange, including the New York Stock Exchange, 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 motivation of the Consolidation is to raise the per share trading price of the Company's common shares to better comply with minimum trading price requirements of such exchanges.

OceanaGold's post-consolidation common shares will be posted for trading on the Toronto Stock Exchange at the opening of trading on the Effective Date, under the current symbol "OGC" and new CUSIP number 675222400.

As at the date of this news release, the Company has 693,379,818 common shares issued and outstanding. Following the completion of the Consolidation on the Effective Date, the Company is expected to have approximately 231,126,566 common shares issued and outstanding, subject to rounding. The exercise or conversion price of all performance rights and deferred share units will be proportionately adjusted reflecting the Consolidation ratio. No fractional post-consolidation common shares will be issued in effect with the Consolidation. Any fractional common share interest of 0.50 or more arising from the Consolidation will be rounded up to the nearest whole number, and any fractional common share interest of less than 0.50 will be cancelled.

Registered shareholders holding pre-Consolidation common shares through the Direct Registration System ("DRS") will be automatically sent a DRS advice by the Company's transfer agent, Computershare Investor Services Inc. ("Computershare"), representing the number of post-Consolidation common shares they hold following the Consolidation and no further action is required to be taken. Beneficial shareholders holding their common shares through intermediaries such as a broker, trustee or other financial institution should note that such intermediaries may have different procedures for processing the Consolidation than those put in place by the Company for the registered shareholders. Beneficial shareholders who have questions regarding how their common shares will be processed in connection with the Consolidation should contact their intermediaries. Registered shareholders holding their pre-Consolidation common shares in certificate forms will receive a letter of transmittal from Computershare containing instructions on how to exchange their pre-consolidation share certificates for post-Consolidation shares.
