(All financial figures in United States dollars unless otherwise stated) On track to achieve production and AISC† guidance, Q4 expected to be the strongest of the year Strong Free Cash Flow† of $155 million, with cash of $729 million and no debt at quarter end Advanced growth projects and delivered exploration success Returned $79 million to shareholders via buybacks and dividends VANCOUVER, BC, Nov. 4, 2026 /PRNewswire/ -- OceanaGold Corporation (TSX: OGC) (NYSE: OGC) ("OceanaGold" or the "Company") reported its operational and financial results for the three and nine months ended September 30, 2026. The consolidated financial statements and Management's Discussion and Analysis ("MD&A") are available at www.oceanagold.com.

OceanaGold (OGC) is rated Buy, driven by production growth, a net cash balance sheet, and discounted valuation versus peers. OGC's portfolio features long-life mines in tier-one jurisdictions, with Waihi North and Katanning projects supporting future growth and mitigating production dips. Despite cost pressures, OGC maintains robust cash flow, ongoing buybacks, and trades at 3.3x EV/EBITDA, near the bottom of its peer group.

OceanaGold trades below what its four mines are worth today, despite having no debt and about US$655 million of cash. I tested the obvious suspect, Haile's cost overruns: they dent the value but do not explain the whole discount. The real discount is time: output dips until the high-grade Wharekirauponga mine starts in 2032.

VANCOUVER, BC, Oct. 6, 2026 /PRNewswire/ -- OceanaGold Corporation (TSX: OGC) (NYSE: OGC) ("OceanaGold" or the "Company") will release its operational and financial results for the third quarter of 2026 after market close on Wednesday, November 4, 2026.

OceanaGold TSE: OGC outlined a growth strategy centered on its Waihi North project in New Zealand, a proposed acquisition of Ausgold and continued exploration, while highlighting free-cash-flow generation and shareholder returns.

Jefferies said strong drilling results at OceanaGold Corporation (TSX:OGC)'s Waihi project support resource conversion, but highlighted plans to expand processing capacity as the more significant development ahead of a January 2027 technical report. The company is evaluating an expansion of processing capacity from 0.8 million tons a year to 1.2 million tons, potentially allowing the Martha and Wharekirauponga (WKP) mines to operate concurrently.
