1 Calculated as trailing 12 month Free Cash Flow^† over the average trailing 12 month market capitalization in USD. 

Gerard Bond, President and CEO of OceanaGold, said: "The third quarter was another period of safe and responsible gold production in which we continued to generate substantial Free Cash Flow, despite it being the planned lowest production quarter of the year. The investment made in waste stripping at Haile and Macraes throughout 2025 has us in fresh open pit ore at both mines now, which positions us for the fourth quarter to be our strongest quarter of the year. Permitting of our Waihi North Project, which includes the high-grade Wharekirauponga underground, is progressing well and we continue to expect approval by year end - in the interim we are advancing early works activities.

The significant Free Cash Flow we have generated year to date of $283 million has allowed us to pay a higher dividend in 2025, continue to strengthen our balance sheet and increase our share buyback program for 2025 by 75% to $175 million. Our focus on investing in attractive organic growth and our disciplined capital allocation framework reflects our continued commitment to creating value and delivering strong returns to our shareholders."

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:

$M, except per share amounts	Q3 2025	Q2 2025	Q3 2024	YTD 2025	YTD 2024

Adjusted earnings per share	0.40	0.51	0.27	1.32	0.40

EBITDA and Adjusted EBITDA

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, OGP 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	Q3 2025	Q2 2025	Q3 2024	YTD 2025	YTD 2024

EBITDA Margin	46 %	50 %	45 %	49 %	39 %

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.

Prior to the first quarter of 2025, Didipio's AISC calculation excluded local corporate G&A costs which is consistent with the calculation of AISC for the other operations. In order to align the Company's reporting of AISC with local reporting requirements in the Philippines, Management has included local corporate G&A costs in Didipio's AISC calculation beginning in the first quarter of 2025.

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	September 30, 2025	December 31, 2024
Revolving credit facility	--	--
Fleet facility^1	--	(2.8)
Unamortized transaction costs	--	1.2
Total debt	--	(1.6)
Cash and cash equivalents	334.9	193.5
Net Cash^†	334.9	191.9

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 Operating Cash Flow per share:

$M, except per share amounts	Q3 2025	Q2 2025	Q3 2024	YTD 2025	YTD 2024
Cash provided by operating activities	227.5	226.9	164.7	626.0	347.8
Changes in working capital	(9.8)	4.9	(3.7)	20.3	(9.7)
Cash flows provided by operating activities before changes in working capital	217.7	231.8	161.0	646.3	338.1
Adjusted weighted average number of common shares - fully diluted	233.0	234.8	242.2	234.4	241.8
Operating Cash Flow per share	$0.93	$0.99	$0.66	$2.76	$1.40

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	Q3 2025	Q2 2025	Q3 2024	YTD 2025	YTD 2024
Cash flows provided by Operating Activities	227.5	226.9	164.7	626.0	347.8
Cash flows used in Investing Activities	(133.1)	(106.8)	(99.0)	(342.7)	(249.1)
Free Cash Flow	94.4	120.1	65.7	283.3	98.7
Adjusted weighted average number of common shares - fully diluted	233.0	234.8	242.2	234.4	241.8
Free Cash Flow per share	$0.41	$0.51	$0.27	$1.21	$0.41
