VANCOUVER, BC, May 7, 2025 /PRNewswire/

OceanaGold Corporation (TSX: OGC) (OTCQX: OCANF) ("OceanaGold" or the "Company") reported its operational and financial results for the three months ended March 31, 2025. The condensed interim consolidated financial statements and Management's Discussion and Analysis ("MD&A") are available at www.oceanagold.com.

First Quarter Highlights

Gerard Bond, President and CEO of OceanaGold, said: "We are pleased with the strong and safe start to the year, with production and cost performance on track with our annual guidance. Our operational leverage to rising gold prices has provided substantial upside this quarter and positions us to generate another year of significant Free Cash Flow in 2025. This strong performance, combined with our exceptional financial position, provides us with the flexibility to continue investing in growth and drive increased shareholder returns.

We are enthusiastic about our organic growth opportunities and exploration potential across all operations. This quarter we made significant progress on open pit waste stripping at Haile and Macraes to unlock access to higher-grade ore later this year, which sets us up for increased production in the fourth quarter and 2026. Our Waihi North Project, which includes the high-grade Wharekirauponga underground, is in the Fast-track permitting process, and we expect it to be approved by year-end. We also discovered the promising new Pisces mineralization at Haile and are investing for further exploration successes at each of our sites."

Share Buyback and Dividend

In the first quarter of 2025, the Company repurchased 7.0 million common shares for consideration of $19.6 million. For 2025, the Board approved the repurchase of up to $100 million of common shares under the Company's current NCIB ("Normal Course Issuer Bid") program announced in July 2024.

OceanaGold has declared a $0.01 per share dividend payable in June 2025. Shareholders of record at the close of business in each jurisdiction on May 21, 2025 (the "Record Date") will be entitled to receive payment of the dividend on June 20, 2025. The dividend payment applies to holders of record of the Company's common shares traded on the Toronto Stock Exchange.

Declaration of Dividend

Wednesday May 7, 2025

Record Date: Wednesday May 21, 2025

Dividend Payment Date: Friday June 20, 2025

Dividends are payable in United States dollars. Shareholders in other jurisdictions can elect to participate in Computershare's international payments service if they want to receive dividends in an alternative currency. This dividend qualifies as an 'eligible dividend' for Canadian income tax purposes.

Proposed Share Consolidation

The Company is seeking shareholder approval in the upcoming Annual General and Special Meeting in June to consolidate all issued and outstanding common shares on the basis of a consolidation ratio, to be determined by the Board, of up to three to one. The primary strategic rationale for this action is to raise the per share trading price of the common shares to more readily comply with minimum trading price requirements of a major U.S. exchange. This move is part of the Company's exploration of the potential benefits of a dual listing, which it believes could lead to increased access to potential investors, increased marketability and enhanced trading liquidity. The 2025 Annual General and Special Meeting of Shareholders will be held virtually on Wednesday, June 4, 2025, via a live webcast accessible on the day at: https://meetnow.global/MYZ5RD5. Please note that the Company has refined some of the revisions to the Articles of the Company (Resolution 6). Shareholders are asked to consider and vote on the further amended Articles, available at: https://investors.oceanagold.com/annual-general-meetings and on SEDAR+ under the Company's name.

Non-IFRS Financial Information

Adjusted Net Profit/(Loss) and Adjusted Earnings/(Loss) per share

These are used by Management to measure the underlying operating performance of the Company. Management believes these measures provide information that is useful to investors because they are important indicators of the strength of the Company's operations and the performance of its core business. Accordingly, such measures are intended to provide additional information and should not be considered in isolation as a substitute for measures of performance prepared in accordance with IFRS. Adjusted Net Profit/(Loss) is calculated as Net Profit/(Loss) less the impact of impairment expenses, write-downs, foreign exchange (gains)/losses, gain on sale of assets, OGP listing costs and restructuring costs related to transitioning certain corporate activities from Australia to Canada.

The following table provides a reconciliation of Adjusted Net Profit/(Loss) and Adjusted Earnings/(Loss) per share:

EBITDA and Adjusted EBITDA

The Company's Management believes that Adjusted EBITDA is a valuable indicator of its ability to generate liquidity by producing operating cash flows to fund working capital needs, service debt obligations and fund capital expenditures. EBITDA is defined as earnings before interest, tax, depreciation and amortization. Adjusted EBITDA is calculated as EBITDA less the impact of impairment expenses, write-downs, gains/losses on disposal of assets, listing costs, foreign exchange gains/losses and other non-recurring costs. EBITDA Margin is calculated as EBITDA divided by revenue.

The following table provides a reconciliation of EBITDA, Adjusted EBITDA and EBITDA Margin:

Cash Costs and AISC

Cash Costs are a common financial performance measure in the gold mining industry; however, it has no standard meaning under IFRS. Management uses this measure to monitor the performance of its mining operations and its ability to generate positive cash flows, both on an individual site basis and an overall company basis. Cash Costs include mine site operating costs plus indirect taxes and selling cost net of by-product sales and are then divided by ounces sold. In calculating Cash Costs, the Company includes copper and silver by-product credits as it considers the cost to produce the gold is reduced as a result of the by-product sales incidental to the gold production process, thereby allowing Management and other stakeholders to assess the net costs of gold production. The measure is not necessarily indicative of cash flow from operations under IFRS or operating costs presented under IFRS.

Management believes that the AISC measure provides additional insight into the costs of producing gold by capturing all of the expenditures required for the discovery, development and sustaining of gold production and allows the Company to assess its ability to support capital expenditures to sustain future production from the generation of operating cash flows, both on an individual site basis and an overall company basis, while maintaining current production levels. Management believes that, in addition to conventional measures prepared in accordance with IFRS, certain investors use this information to evaluate the Company's performance and ability to generate cash flow per ounce sold. AISC is calculated as the sum of Cash Costs, capital expenditures and exploration costs that are sustaining in nature and corporate G&A costs. AISC is divided by ounces sold to arrive at AISC per ounce.

The following table provides a reconciliation of consolidated Cash Costs and AISC:

Net Cash/(Debt)

Net Cash/(Debt) has been calculated as total debt less cash and cash equivalents. Management believes this is a useful indicator to be used in conjunction with other liquidity and leverage ratios to assess the Company's financial health. Prior to 2024, lease liabilities were included in the calculation of Net Cash/(Debt). The change in respect of 2024 is consistent with the generally adopted approach to the calculation of Net Cash/(Debt). The comparative quarters have been recalculated excluding lease liabilities.

The following table provides a reconciliation of Net Cash/(Debt):

Operating Cash Flow per share

Operating Cash Flow per share before working capital movements is calculated as the cash flows provided by operating activities adjusted for changes in working capital then divided by the fully diluted adjusted weighted average number of common shares issued and outstanding.

The following table provides a reconciliation of total fully diluted cash Operating Cash Flow per share:

Free Cash Flow

Free Cash Flow has been calculated as cash flows from operating activities, less cash flow used in investing activities. Management believes Free Cash Flow is a useful indicator of the Company's ability to generate cash flow and operate net of all expenditures, prior to any financing cash flows. Free Cash Flow per share is calculated as the Free Cash Flow divided by the fully diluted adjusted weighted average number of common shares issued and outstanding.

The following table provides a reconciliation of Free Cash Flow:
