The following operating and financial results are based on second-quarter gold equivalent production:

Production: Kinross produced 512,574 Au eq. oz. in Q2 2025, compared with 535,338 Au eq. oz. in Q2 2024. Higher production from Fort Knox, with the commencement of higher-grade, higher-recovery ore feed from Manh Choh in the second half of 2024, and higher production from Paracatu, was offset by lower production from Tasiast and Round Mountain, as planned.

Average realized gold price8: The average realized gold price in Q2 2025 was $3,284 per ounce, compared with $2,342 per ounce in Q2 2024.

Revenue: During the second quarter, revenue increased to $1,728.5 million, compared with $1,219.5 million during Q2 2024. The 42% year-over-year increase is due to the increase in the average realized gold price.

Production cost of sales: Production cost of sales per Au eq. oz. sold2 was $1,080 for the quarter, compared with $1,029 in Q2 2024. Attributable production cost of sales per Au eq. oz. sold1 was $1,074 for the quarter, compared with $1,029 in Q2 2024.

Attributable production cost of sales per Au oz. sold on a by-product basis1 was $1,044 in Q2 2025, compared with $989 in Q2 2024, based on attributable gold sales of 501,628 ounces and attributable silver sales of 650,026 ounces.

Margins4: Kinross’ margin per Au eq. oz. sold increased by 68% to $2,204 for Q2 2025, compared with the Q2 2024 margin of $1,313, outpacing the 40% increase in average realized gold price.

Attributable all-in sustaining cost1: Attributable all-in sustaining cost per Au eq. oz. sold was $1,493 in Q2 2025, compared with $1,387 in Q2 2024.

In Q2 2025, attributable all-in sustaining cost per Au oz. sold on a by-product basis was $1,469, compared with $1,357 in Q2 2024.

Operating cash flow3: Operating cash flow increased to $992.4 million for Q2 2025, compared with $604.0 million for Q2 2024.

Attributable adjusted operating cash flow1 for Q2 2025 increased to $843.9 million, compared with $478.3 million for Q2 2024.

Attributable free cash flow1: Attributable free cash flow increased by 87% to $646.6 million in Q2 2025, compared with $345.9 million in Q2 2024.

Reported earnings5: Reported net earnings more than doubled to $530.7 million for Q2 2025, or $0.43 per share, compared with reported net earnings of $210.9 million, or $0.17 per share, for Q2 2024.

Adjusted net earnings6 more than tripled to $541.0 million, or $0.44 per share, for Q2 2025, compared with $174.7, or $0.14 per share, for Q2 2024.

Attributable capital expenditures1: Attributable capital expenditures increased to $301.8 million for Q2 2025, compared with $264.5 million for Q2 2024. The increase was driven by the ramp-up of development activities at Great Bear, Bald Mountain Redbird Phase 1 and La Coipa Phase 7, partially offset by lower spending on capital development due to mine sequencing at Fort Knox and Manh Choh.

Balance sheet

As of June 30, 2025, Kinross had cash and cash equivalents of $1,136.5 million, compared with $694.6 million at March 31, 2025, and net debt9 of approximately $100 million.

The Company had additional available credit10 of $1.6 billion and total liquidity7 of approximately $2.8 billion as of June 30, 2025.

Return of capital to shareholders

Reflecting the Company’s financial strength, Kinross reactivated its share buyback program in April 2025, while continuing its quarterly dividend program.

Kinross repurchased approximately $170 million in shares during the quarter, and approximately $225 million to date (representing 15.2 million shares). Including its quarterly dividend, Kinross has returned approximately $300 million in capital to shareholders to date in 2025.

Kinross continues to target returning a minimum of $650 million to shareholders for the full year, including a minimum of $500 million in share repurchases.

As part of its continuing quarterly dividend program, the Company declared a dividend of $0.03 per common share payable on September 4, 2025, to shareholders of record as of August 21, 2025.

Operating results

Mine-by-mine summaries for 2025 second-quarter operating results may be found on pages 10 and 14 of this news release. Highlights include the following:

At Tasiast, production decreased quarter-over-quarter and year-over-year driven by planned lower grades and lower throughput. The higher recoveries following a number of optimization initiatives to the mill were partially offset by planned lower grades year-over-year. Cost of sales per ounce sold increased compared with the previous quarter and Q2 2024 due to lower production. Tasiast remains on track to meet its annual guidance.

Production at Paracatu increased quarter-over-quarter due to higher throughput, partially offset by lower grades. Year-over-year production increased due to higher grades and recoveries partially offset by an expected decrease in throughput, as per planned mine sequencing which moved into harder, higher-grade ore this year. Cost of sales per ounce sold was in line with the previous quarter and decreased compared with Q2 2024 due to the increase in production.

At La Coipa, production increased quarter-over-quarter due to timing of ounces processed through the mill, partially offset by lower grades as a result of decreased ore tonnes mined from the pit and increased feed from low-grade stockpiles driven by higher groundwater inflows into the pits than anticipated. Relative to Q2 2024, production decreased also due to lower grades with higher feed from low-grade stockpiles. In the second half of the year, production is expected to increase as mining transitions to higher-grade ore from Phase 7, and the mine remains on track to meet its annual production guidance. Cost of sales per ounce sold was higher quarter-over-quarter as a result of the lower grades and higher royalty costs, and year-over-year as a result of the decrease in production and higher royalty, labour and contractor costs. Permitting work for mine life extensions continues, including the submission of the Environmental Impact Assessment during the quarter.

At Fort Knox, production was largely in line quarter-over-quarter, and increased year-over-year as a result of the contribution of Manh Choh’s higher-grade, higher-recovery ore starting in the second half of 2024. Cost of sales per ounce sold increased quarter-over-quarter due to higher processing costs and the timing of ounces recovered from the heap leach pads. Year-over-year costs decreased as a result of the increase in production, partially offset by higher royalty and reagent costs related largely to the start of Manh Choh production.

At Round Mountain, production was higher quarter-over-quarter driven by higher grades. Production decreased year-over-year as a result of lower mill grades and fewer ounces recovered from the heap leach pads as per planned mine sequencing as the site transitions from Phase W to Phase S.

At Bald Mountain, production was higher quarter-over-quarter and year-over-year largely as a result of strong grades and timing of ounces recovered from the heap leach pads, partially offset by fewer tonnes of ore stacked. Cost of sales per ounce sold was lower quarter-over-quarter and year-over-year as a result of the increase in production and higher proportion of capital development tonnes as mining at Redbird Phase I continues to ramp-up.

Development and exploration projects

Great Bear

At Great Bear, Kinross continues to progress its AEX program, permitting and detailed engineering for the Main Project.

AEX construction commenced in Q4 2024, earthwork activities are underway, and the AEX camp is nearing completion. Initial development of the exploration decline is on target for December 2025, subject to permitting.

For the Main Project, Kinross is progressing detailed engineering on the mill, the tailings management facility, and other site infrastructure. Initial procurement activities for major process equipment have commenced, with awards planned to start in late 2025, and manufacturing for a few long lead items is expected to commence in 2026.

In order to advance the Impact Statement (IS) on a timely basis, the Company is coordinating with the Impact Assessment Agency of Canada (IAAC) on a staged filing process. The Company intends to file the majority of the technical chapters by year end and the remaining chapters by the end of Q1 2026. This approach will underpin a robust IS filing with the necessary technical and Indigenous contributions to help facilitate an efficient review process by IAAC.

Kinross also advanced its regional exploration drilling program during the quarter, targeting favorable geophysical signatures as well as lithological contacts, looking for new, near-surface mineralization.

Round Mountain Phase X

Decline development at Round Mountain Phase X is advancing well, with over 4,500 metres developed to date. Extensive infill drilling has been completed in both the upper zone and lower zones, with results continuing to intersect strong widths and grades, and extension drilling indicating continuation of mineralization down dip outside the original exploration target. Highlights include:

  • Upper Zone:

◦DX-0115 – 114m @ 3.6 g/t ◾Including 6m @ 13.5 g/t ◦DX-0116 – 76m @ 4.6g/t ◾Including 3m @ 13.4 g/t ◦DX-0128 – 77m @ 4.0 g/t ◾Including 6m @ 13.0 g/t ◦DX-0129 – 85m @ 5.4 g/t ◾Including 8m @ 25.5 g/t ◦DX-0132 – 165m @ 4.0 g/t ◾Including 6m @ 31.4 g/t ◦DX-0139 – 75m @ 3.1 g/t ◾Including 5m @ 13.6 g/t

  • Lower Zone:

◦DX-0146 – 43m @ 4.6 g/t ◾Including 8m @ 11.4 g/t ◦DX-0147 – 82m @ 3.1 g/t ◾Including 8m @ 8.1 g/t ◦DX-0170 – 105m @ 5.1 g/t ◾Including 15m @ 7.8 g/t ◦DX-0175 – 71m @ 3.4 g/t ◾Including 6m @ 7.7 g/t

  • Extension Drilling:

◦DX-0162 – 67m @ 3.2 g/t ◾Including 5m @ 11.0 g/t ◦DX-0163 – 88m @ 2.7 g/t ◾Including 6m @ 8.8 g/t

Engineering work and technical studies are advancing well to support potential project execution at Phase X.

Kinross plans to provide a project, resource and economics update with year-end results.

See Appendix A for a Round Mountain Phase X long section.

Curlew Basin exploration

Drilling at Curlew continues to intersect high grades and strong widths at both North Stealth and K5, indicating potential to further improve the quality of the resource and the mine plan with additions of high margin mineralization. Highlights include (true width):

◦ST-1498 – 6.0m @ 14.3 g/t Au ◦ST-1494 – 7.4m @ 8.9 g/t Au ◦K5-1266 – 7.5m @ 7.8 g/t Au ◦K5-1270 – 4.6m @ 12.4 g/t Au

Extension of the underground declines is progressing well with over 800 metres developed year-to-date, focused on providing drilling access to follow up on the high grade 2023 discovery at Roadrunner and to extend mineralization in the high grade North Stealth area.

Technical studies and detailed engineering are also progressing well at Curlew.

See Appendix A for a Curlew cross section.

Bald Mountain Redbird

At Redbird, mining is advancing on schedule. Studies and detailed engineering related to the potential Phase 2 extension of Redbird are progressing well, including engineering related to the heap leach pad expansion, technical studies and mine plan optimization work. Exploration drilling and technical studies are also progressing, targeting satellite pit opportunities on the large Bald Mountain property, which could potentially augment the production profile from Redbird 2.

Lobo-Marte

Kinross is progressing baseline studies to support the Environmental Impact Assessment (EIA) for the Lobo-Marte project. Lobo-Marte continues to be a potential large, low-cost mine and Kinross is committed to progressing next steps to advance the project.

Sustainability

Following the publication of Kinross’ 2024 Sustainability Report and summary, below are several water-related highlights, a material sustainability topic for the Company and its stakeholders. Kinross’ water management standard prioritizes water supply security, water conservation and stewardship, and prevention of downstream environmental impacts. There is a strong focus on water efficiency, with a high water recycling rate of 75%, as well as maintaining water quality at locations both near and far from sites. Kinross also maintained its conformance with the Responsible Gold Mining Principles, which include principles for water efficiency and quality.

In Chile, La Coipa contributed to this efficiency through an optimization program of the main processing circuits which resulted in lower water loss going to the dry stack tailings. Near Maricunga, wetland restoration resulted in the resurgence of ecosystem services and the return of native plant species.

At all of the Company’s development projects, science-based methods are utilized to ensure strong baseline information, including environmental DNA studies for the Great Bear project and watershed groundwater modeling for the Lobo-Marte project.

At Fort Knox in Alaska, fish populations continue to thrive at Fish Creek based on continuous monitoring by the Alaska department of Fish and Game since the late 1990s. Fish Creek was a historic placer mining area, reclaimed by Kinross in the early 1990s for the benefit of the local communities. Also in Alaska, Kinross continued its long-standing partnership with Trout Unlimited and the Alaska Abandoned Mine Restoration Initiative, with sustained progress in the recovery of fish populations in Resurrection Creek, south of Anchorage, also a placer mining area.

Reconciliation of non-GAAP financial measures and ratios

The Company has included certain non-GAAP financial measures and ratios in this document. These financial measures and ratios are not defined under IFRS and should not be considered in isolation. The Company believes that these financial measures and ratios, together with financial measures and ratios determined in accordance with IFRS, provide investors with an improved ability to evaluate the underlying performance of the Company. The inclusion of these financial measures and ratios is meant to provide additional information and should not be used as a substitute for performance measures prepared in accordance with IFRS. These financial measures and ratios are not necessarily standard and therefore may not be comparable to other issuers.

Adjusted Net Earnings and Adjusted Net Earnings per Share

Adjusted net earnings and adjusted net earnings per share are non-GAAP financial measures and ratios which determine the performance of the Company, excluding certain impacts which the Company believes are not reflective of the Company’s underlying performance for the reporting period, such as the impact of foreign exchange gains and losses, reassessment of prior year taxes and/or taxes otherwise not related to the current period, impairment charges (reversals), gains and losses and other one-time costs related to acquisitions, dispositions and other transactions, and non-hedge derivative gains and losses. Although some of the items are recurring, the Company believes that they are not reflective of the underlying operating performance of its current business and are not necessarily indicative of future operating results. Management believes that these measures and ratios, which are used internally to assess performance and in planning and forecasting future operating results, provide investors with the ability to better evaluate underlying performance, particularly since the excluded items are typically not included in public guidance. However, adjusted net earnings and adjusted net earnings per share measures and ratios are not necessarily indicative of net earnings and earnings per share measures and ratios as determined under IFRS.

The following table provides a reconciliation of net earnings to adjusted net earnings for the periods presented:

Attributable Free Cash Flow

Attributable free cash flow is a non-GAAP financial measure and is defined as net cash flow provided from operating activities less attributable capital expenditures and non-controlling interest included in net cash flows provided from operating activities. The Company believes that this measure, which is used internally to evaluate the Company’s underlying cash generation performance and the ability to repay creditors and return cash to shareholders, provides investors with the ability to better evaluate the Company’s underlying performance. However, this measure is not necessarily indicative of operating earnings or net cash flow provided from operating activities as determined under IFRS.

See pages 21 and 22 for details of the footnotes referenced within the table above.

Attributable Adjusted Operating Cash Flow

Attributable adjusted operating cash flow is a non-GAAP financial measure and is defined as net cash flow provided from operating activities excluding changes in working capital, certain impacts which the Company believes are not reflective of the Company’s regular operating cash flow, and net cash flows provided from operating activities, net of working capital changes, relating to non-controlling interests. Working capital can be volatile due to numerous factors, including the timing of tax payments. The Company uses attributable adjusted operating cash flow internally as a measure of the underlying operating cash flow performance and future operating cash flow-generating capability of the Company. However, the attributable adjusted operating cash flow measure is not necessarily indicative of net cash flow provided from operating activities as determined under IFRS.

Attributable Average Realized Gold Price per Ounce

Attributable average realized gold price per ounce is a non-GAAP ratio which calculates the average price realized from gold sales attributable to the Company. The Company believes that this measure provides a more accurate measure with which to compare the Company's gold sales performance to market gold prices. The following table provides a reconciliation of attributable average realized gold price per ounce for the periods presented:

Attributable Production Cost of Sales per Equivalent Ounce Sold

Production cost of sales per equivalent ounce sold is defined as production cost of sales, as reported on the interim condensed consolidated statement of operations, divided by the total number of gold equivalent ounces sold. This measure converts the Company’s non-gold production into gold equivalent ounces and credits it to total production.

Attributable production cost of sales per equivalent ounce sold is a non-GAAP ratio and is defined as attributable production cost of sales divided by the attributable number of gold equivalent ounces sold. This measure converts the Company’s attributable non-gold production into gold equivalent ounces and credits it to total attributable production. Management uses this measure to monitor and evaluate the performance of its operating properties that are attributable to its shareholders.

The following table provides a reconciliation of production cost of sales and attributable production cost of sales per equivalent ounce sold for the periods presented:

Attributable Production Cost of Sales per Ounce Sold on a By-Product Basis

Attributable production cost of sales per ounce sold on a by-product basis is a non-GAAP ratio which calculates the Company’s non-gold production as a credit against its per ounce production costs, rather than converting its non-gold production into gold equivalent ounces and crediting it to total production, as is the case in co-product accounting. Management believes that this ratio provides investors with the ability to better evaluate Kinross’ production cost of sales per ounce on a comparable basis with other major gold producers who routinely calculate their cost of sales per ounce using by-product accounting rather than co-product accounting.

Attributable All-In Sustaining Cost and All-In Cost per Ounce Sold on a By-Product Basis

Attributable all-in sustaining cost and all-in cost per ounce sold on a by-product basis are non-GAAP financial measures and ratios, as applicable, calculated based on guidance published by the World Gold Council (“WGC”). The WGC is a market development organization for the gold industry and is an association whose membership comprises leading gold mining companies including Kinross. Although the WGC is not a mining industry regulatory organization, it worked closely with its member companies to develop these metrics. Adoption of the all-in sustaining cost and all-in cost metrics is voluntary and not necessarily standard, and therefore, these measures and ratios presented by the Company may not be comparable to similar measures and ratios presented by other issuers. The Company believes that the all-in sustaining cost and all-in cost measures complement existing measures and ratios reported by Kinross.

All-in sustaining cost includes both operating and capital costs required to sustain gold production on an ongoing basis. The value of silver sold is deducted from the total production cost of sales as it is considered residual production, i.e. a by-product. Sustaining operating costs represent expenditures incurred at current operations that are considered necessary to maintain current production. Sustaining capital represents capital expenditures at existing operations comprising mine development costs, including capitalized development, and ongoing replacement of mine equipment and other capital facilities, and does not include capital expenditures for major growth projects or enhancement capital for significant infrastructure improvements at existing operations.

All-in cost is comprised of all-in sustaining cost as well as operating expenditures incurred at locations with no current operation, or costs related to other non-sustaining activities, and capital expenditures for major growth projects or enhancement capital for significant infrastructure improvements at existing operations.

Attributable all-in sustaining cost and all-in cost per ounce sold on a by-product basis are calculated by adjusting production cost of sales, as reported on the interim condensed consolidated statements of operations, as follows:

Attributable All-In Sustaining Cost and All-In Cost per Equivalent Ounce Sold

The Company also assesses its attributable all-in sustaining cost and all-in cost on a gold equivalent ounce basis. Under these non-GAAP financial measures and ratios, the Company’s production of silver is converted into gold equivalent ounces and credited to total production.

Attributable all-in sustaining cost and all-in cost per equivalent ounce sold are calculated by adjusting production cost of sales, as reported on the interim condensed consolidated statements of operations, as follows:
