• Record quarterly and annual revenue of $427 million and $1.29 billion, respectively
• Record quarterly and annual Net Profit^† of $103 million and $192 million, respectively
• Adjusted EPS^† of $0.15, an increase of 67% from the prior quarter
• Fourth quarter EBITDA Margin^† of 58% and Operating Cash Flow Per Share^† of $0.36
• Record quarterly and annual Free Cash Flow^† of $147 million and $245 million, respectively

Gerard Bond, President and CEO of OceanaGold, said "The fourth quarter was tremendous, delivering numerous operational and Company records, highlighted by record quarterly Free Cash Flow of $147 million. These strong results were driven by record production at Haile and a strong performance by both Macraes and Waihi. We continued to invest at all four operations while increasing shareholders' ownership of the Company by fully repaying the credit facility and actively buying back shares, finishing the year with net cash of $192 million. In 2024 we also successfully completed a number of major milestones notably the OceanaGold Philippines IPO, the ramp-up of Haile's Horseshoe underground mine, and the release of exceptional results in the Waihi District pre-feasibility study.

Looking forward, we expect another year of strong Free Cash Flow in 2025, and a significant step-up in gold production and Free Cash Flow in 2026. We will continue to invest in our organic growth and exploration projects and increase capital returns to our shareholders via the dividend and share-buyback programs. I am also very excited by the value enhancing catalysts we have in 2025, such as obtaining the permits  and commencing construction at the high-grade Wharekirauponga underground mine, and further exploration success at each of our sites."

Multi-Year Outlook

The Company maintains a strong multi-year outlook, with 20% growth in gold production from 2024 levels by 2026.

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.

Prior to the first quarter of 2024, Adjusted Net Profit/(Loss) was calculated using an adjustment for a specific portion of unrealized foreign exchange gains/losses rather than the total foreign exchange gain/loss. The comparative quarters have been recalculated adjusting for all foreign exchange gains/ losses.

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

$M, except per share amounts	Q4 2024	Q3 2024	Q4 2023	2024	2023

Adjusted earnings per share	0.15	0.09	0.01	0.29	0.17

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.

Prior to the first quarter of 2024, Adjusted EBITDA was calculated using an adjustment for a specific portion of unrealized foreign exchange gains/losses rather than the total foreign exchange gain/loss. The comparative quarters have been recalculated adjusting for all foreign exchange gains/losses.

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

$M	Q4 2024	Q3 2024	Q4 2023	2024	2023

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):

$M	December 31, 2024	December 31, 2023
Revolving credit facility	—	(135.0)
Fleet facility^1	(2.8)	(4.4)
Unamortized transaction costs	1.2	1.2
Total debt	(1.6)	(138.2)
Cash and cash equivalents	193.5	61.7
Net Cash (Debt)^†	191.9	(76.5)

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:

$M, except per share amounts	Q4 2024	Q3 2024	Q4 2023	2024	2023
Cash provided by operating activities	246.1	164.7	94.8	593.9	384.2

Operating Cash Flow per share	$0.36	$0.22	$0.12	$0.83	$0.56

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:

$M, except per share amounts	Q4 2024	Q3 2024	Q4 2023	2024	2023
Cash flows provided by Operating Activities	246.1	164.7	94.8	593.9	384.2
Cash flows used in Investing Activities	(99.6)	(99.0)	(78.7)	(348.7)	(341.8)
Free Cash Flow	146.5	65.7	16.1	245.2	42.4
Adjusted weighted average number of common shares - fully diluted	724.6	726.5	722.6	724.8	722.6
Free Cash Flow per share	$0.20	$0.09	$0.02	$0.34	$0.06
