Lundin Mining Pre-Announces Items Impacting the First Quarter 2025 Results

VANCOUVER, BC, April 17, 2025 /PRNewswire/ -- (TSX: LUN) (Nasdaq Stockholm: LUMI) Lundin Mining Corporation ("Lundin Mining" or the "Company") is pre-announcing certain items impacting the Company's quarterly earnings, adjusted earnings before interest, taxes, depreciation and amortization ("adjusted EBITDA")¹, adjusted earnings¹ and adjusted earnings per share¹.

Revenue and Provisional Pricing Adjustments

Revenue in the first quarter 2025 is expected to be positively impacted by unaudited provisional pricing adjustments on prior period concentrate sales by approximately $45 million on a pre-tax basis. These adjustments primarily include upward adjustments in relation to copper and gold sales, partially offset by downward adjustments on molybdenum sales.

Foreign Exchange and Derivatives

Items of significant impact in the first quarter 2025 are expected to include unaudited realized losses on foreign exchange derivative contracts of approximately $12 million on a pre-tax basis primarily due to Canadian dollar derivative contracts entered into in relation to the cash consideration for Filo Corp. Additionally, unaudited realized foreign exchange losses of approximately $10 million on a pre-tax basis were primarily due to strengthening of the Brazilian real ("BRL") and Chilean peso ("CLP") against the US dollar during the quarter.

In the first quarter 2025 the Company is also expected to recognize certain non-cash items that will impact the Company's earnings but not adjusted EBITDA, adjusted earnings or adjusted earnings per share. These include unaudited unrealized foreign exchange losses of approximately $9 million on a pre-tax basis and an unaudited unrealized gain of approximately $36 million on a pre-tax basis related to the mark-to-market valuation of the Company's foreign exchange and commodity derivative contracts, primarily due to strengthening of the BRL and CLP against the US dollar during the quarter, partially offset by unrealized losses on gold derivative contracts.
