First Quantum Minerals Announces Cash Tender Offer to Purchase Any and All of Its Outstanding 6.875% Senior Notes Due 2027

(In United States dollars, except where noted otherwise)

TORONTO, Aug. 06, 2025 (GLOBE NEWSWIRE) -- First Quantum Minerals Ltd. (the "Company" or "First Quantum") (TSX:FM) today announced that it has commenced an offer to purchase for cash (the "Tender Offer") any and all of its outstanding 6.875% Senior Notes due 2027 (the "Notes") from holders of the Notes ("Holders"), as further described in the offer to purchase dated the date hereof (the "Offer to Purchase") and the related Notice of Guaranteed Delivery.

The Tender Offer will expire at 5:00 pm, New York City time, on August 12, 2025 (such date, as may be extended, the "Expiration Date"). The consideration for each $1,000 principal amount of Notes tendered prior to the Expiration Date and accepted for purchase pursuant to the Tender Offer shall be the "Notes Consideration" and will be calculated by the Dealer Managers (as defined below) as set forth in the table below in a manner described in the Offer to Purchase by reference to the fixed spread (the "Fixed Spread") specified below plus the yield based on the bid-side price of the U.S. Treasury Reference Security specified below (the "Reference Security") as quoted on the Bloomberg Bond Trader FIT3 series of pages (the "Reference Page") at 2:00 p.m., New York City time, on the date referred to in the Offer to Purchase as the "Price Determination Date." In addition, Holders who validly tender and do not validly withdraw their Notes in the Tender Offer will be paid a cash amount equal to accrued and unpaid interest from the last interest payment date up to, but not including, the Settlement Date (as defined in the Offer to Purchase). For the avoidance of doubt, any Notes accepted for purchase pursuant to the Offer will cease to accrue interest on and after the Settlement Date.

Tendered Notes may be withdrawn at any time at or prior to the Expiration Date and no tenders will be valid if submitted after the Expiration Date. Upon completion of the Tender Offer, the Notes accepted for purchase will be canceled.
