NEWMONT Corp /DE/

Newmont has developed gold equivalent ounce (“GEO”) metrics to provide a comparable basis for analysis and understanding of our operations and performance related to copper, silver, lead and zinc. Gold equivalent ounces are calculated as pounds or ounces produced or sold multiplied by the ratio of the other metals’ price to the gold price, using the metal prices in the table below:

(1)Effective January 1 2025, the Company updated the metal prices utilized for the GEO calculation. Utilizing the updated 2025 pricing resulted in 317 thousand and 320 thousand fewer calculated "gold equivalent ounces - other metals" produced and sold, respectively, than would have been calculated using the 2024 pricing for the year ended December 31, 2025.

(2)Effective January 1, 2026, the GEO calculation was updated to use the following metal price assumptions: Gold ($4,000/oz), Copper ($5.00/lb.), Silver ($50.00/oz), Lead ($0.90/lb.), and Zinc ($1.30/lb.). This update to the GEO calculation will have an impact on the calculated gold equivalent ounces, and will impact how costs are allocated to the respective GEOs, particularly resulting in higher costs allocated to gold. Utilizing the updated 2026 pricing would have resulted in 479 and 487 fewer calculated "gold equivalent ounces - other metals" produced and sold, respectively, than was calculated using the 2025 pricing for the year ended December 31, 2025.

(2)All-in sustaining costs is a non-GAAP financial measure. Refer to Non-GAAP Financial Measures below.

(3)Sites acquired through the Newcrest transaction during the fourth quarter of 2023. Refer to Note 3 to the Consolidated Financial Statements for further information on the Newcrest transaction.

(4)In October 2025, the Company declared commercial production at its Ahafo North project in Ghana resulting in classification as a reportable segment. As such, the comparative results of operations information is not meaningful. Refer to Note 4 to the Consolidated Financial Statements for further information.

(5)During the first quarter of 2025, mining and processing operations at the site were temporarily suspended due to safety events (the "Cerro Negro shutdowns"). Full operations resumed in April 2025. In the second quarter of 2024, the Company suspended operations at Cerro Negro to conduct a full investigation into the tragic fatalities of two members of the Newmont workforce on April 9, 2024. The site ramped up to full operations in June 2024.

(6)These sites were classified as held for sale beginning in the first quarter of 2024, and as such, the Company ceased recording depreciation and amortization in March 2024. Telfer was divested at December 31, 2024. All other sites previously classified as held for sale were divested at December 31, 2025. As a result, the comparative results of these operations are not meaningful. Refer to Note 3 of the Consolidated Financial Statements for further information.

(7)During the second quarter of 2024, seepage points were detected on the outer wall and around the tailings storage facility at Telfer and we temporarily ceased placing new tailings on the facility. Production resumed at the end of the third quarter of 2024. During the fourth quarter of 2024, we recognized a benefit of $50 related to business insurance proceeds as a result of the event, recorded in Costs applicable to sales.

(8)All-in sustaining costs and Depreciation and amortization include expense for Corporate and Other.

(9)For the years ended December 31, 2025, 2024 and 2023, Cadia produced 180 million, 191 million, and 36 million pounds of copper, respectively.

(10)For the years ended December 31, 2025, 2024 and 2023, Boddington produced 53 million, 83 million and 98 million pounds of copper, respectively.

(11)For the year ended December 31, 2025, Peñasquito produced 28 million ounces of silver, 216 million pounds of lead and 509 million pounds of zinc. For the year ended December 31, 2024, Peñasquito produced 33 million ounces of silver, 212 million pounds of lead and 569 million pounds of zinc. For the year ended December 31, 2023, Peñasquito produced 18 million ounces of silver, 113 million pounds of lead and 230 million pounds of zinc.

(12)For the years ended December 31, 2025, 2024 and 2023, Red Chris produced 63 million, 58 million, and 8 million pounds of copper, respectively.

(13)For the years ended December 31, 2024 and 2023, Telfer produced 6 million and 3 million pounds of copper, respectively.

(14)Income and expenses of equity method investments are included in Equity income (loss) of affiliates. Refer to Note 15 to the Consolidated Financial Statements for further discussion of our equity method investments.

(15)The Fruta del Norte mine is wholly owned and operated by Lundin Gold, and is accounted for as an equity method investment on a quarter lag. Due to the quarter lag, comparative results of operations are not meaningful for the year ended December 31, 2025.
