On February 26, 2026, First Quantum Minerals Ltd., a Canadian-based copper, nickel and gold producer with operations in Zambia and Mauritania and additional development assets including Cobre Panamá and Taca Taca, completed the issuance of US$1.5 billion aggregate principal amount of 6.375 percent senior unsecured notes due 2036. The notes were issued at par (100.000 percent), with interest payable semi-annually from the issue date, and are guaranteed by certain of First Quantum's subsidiaries. The offering was launched on February 11, 2026 at an initial size of US$1.35 billion and was upsized at pricing the same day to US$1.5 billion following investor demand. The notes were offered outside of Canada and the United States in reliance on customary exemptions from prospectus and registration requirements (including the EU Prospectus Regulation and the UK prospectus regime), consistent with a Rule 144A and Regulation S high-yield format. First Quantum applied the gross proceeds, together with cash on its balance sheet, to redeem in full the US$1.35 billion aggregate principal amount outstanding of its existing 9.375 percent senior secured second lien notes due 2029, to repay certain drawn revolving credit facility amounts, and to pay transaction fees, costs and expenses. The redemption of the 2029 notes was completed concurrently with the closing of the new notes on February 26, 2026, effecting a refinancing that materially extended the maturity profile and reduced the coupon on the refinanced debt.
