SSR MINING INC.

The Company has included certain non-GAAP financial measures to assist in understanding the Company's financial results. The non-GAAP financial measures are employed by the Company to measure its operating and economic performance and to assist in decision-making, as well as to provide key performance information to senior management. The Company believes that, in addition to conventional measures prepared in accordance with GAAP, certain investors and other stakeholders will find this information useful to evaluate the Company's operating and financial performance; however, these non-GAAP performance measures do not have any standardized meaning. These performance measures are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. These non-GAAP measures should be read in conjunction with the Company's Consolidated Financial Statements.

Non-GAAP Measure - Cash Costs and AISC

Cash Costs and All-In Sustaining Costs (“AISC”) per payable ounce of gold and respective unit cost measures are non-U.S. GAAP metrics developed by the World Gold Council to provide transparency into the costs associated with producing gold and provide a standard for comparison across the industry. The World Gold Council is a market development organization for the gold industry.

The Company uses cash costs per ounce of precious metals sold to monitor its operating performance internally. The most directly comparable measure prepared in accordance with GAAP is Cost of sales. The Company believes this measure provides investors and analysts with useful information about its underlying cash costs of operations and the impact of by-product credits on its cost structure. The Company also believes it is a relevant metric used to understand its operating profitability. When deriving the cost of sales associated with an ounce of precious metal, the Company includes by-product credits, which allows management and other stakeholders to assess the net costs of gold and silver production.

AISC includes total Cost of sales incurred at the Company’s mining operations, which forms the basis of cash costs. Additionally, the Company includes sustaining capital expenditures, sustaining mine-site exploration and evaluation costs, reclamation cost accretion and amortization, and general and administrative expenses. This measure seeks to reflect the ongoing cost of gold and silver production from current operations; therefore, growth capital is excluded. The Company determines sustaining capital to be capital expenditures that are necessary to maintain current production and execute the current mine plan. The Company determines growth capital to be those payments used to develop new operations or related to projects at existing operations where those projects will materially benefit the operation.

The Company believes that AISC provides additional information to management and stakeholders that provides visibility to better define the total costs associated with production and better understanding of the economics of the Company's operations and performance compared to other producers.

In deriving the number of ounces of precious metal sold, the Company considers the physical ounces available for sale after the treatment and refining process, commonly referred to as payable metal, as this is what is sold to third parties.

The following tables provide a reconciliation of Cost of sales to Cash costs and AISC:

(1)The reported AISC amounts reflect results for CC&V from the date of acquisition on February 28, 2025 through December 31, 2025.

(3)Care and maintenance expense only includes direct costs not associated with environmental reclamation and remediation costs, as depreciation is not included in the calculation of AISC.

(4)Gold equivalent ounces are calculated multiplying the silver ounces by the ratio of the silver price to the gold price, using the average closing commodity prices for the period. The Company does not include by-products in the gold equivalent ounce calculations. Gold equivalent ounces sold may not re-calculate based on amounts presented in this table due to rounding.

(3)Gold equivalent ounces are calculated multiplying the silver ounces by the ratio of the silver price to the gold price, using the average closing commodity prices for the period. The Company does not include by-products in the gold equivalent ounce calculations. Gold equivalent ounces sold may not re-calculate based on amounts presented in this table due to rounding.

(2)During the fourth quarter of 2023, the Company identified an adjustment of $10.5 million related to 2023 asset retirement cost depreciation, which was erroneously excluded from Puna's AISC calculation. The Company recognized the total adjustment in the fourth quarter of 2023 and the impact to prior periods was not material. The adjustment only impacts the AISC calculation and does not impact Reclamation and remediation costs or Net income (loss) attributable to SSR Mining shareholders in the Company's Consolidated Statements of Operations.

The Company does not include by-products in the gold equivalent ounce calculations. Gold equivalent ounces sold may not re-calculate based on amounts presented in this table due to rounding.

Non-GAAP Measure - Adjusted Attributable Net Income

Adjusted attributable net income (loss) and adjusted attributable net income (loss) per share are used by management and investors to measure the Company’s underlying operating performance. The most directly comparable financial measures prepared in accordance with GAAP are Net income (loss) attributable to SSR Mining shareholders and Net income (loss) per share attributable to SSR Mining shareholders. Adjusted attributable net income (loss) is defined as net income (loss) adjusted to exclude the after-tax impact of specific items that are significant, but not reflective of the Company’s underlying operations, including impairment charges and inflationary impacts on tax balances.

The following table provides a reconciliation of Net income (loss) attributable to SSR Mining shareholders to adjusted net income (loss) attributable to SSR Mining shareholders:

Non-GAAP Measure - Earnings Before Interest, Taxes, Depreciation and Amortization (“EBITDA”) and Adjusted EBITDA

EBITDA represents net income (loss) before interest, taxes, depreciation, and amortization. EBITDA is an indicator of the Company’s ability to generate liquidity by producing operating cash flow to fund working capital needs, service debt obligations, and fund capital expenditures.

Adjusted EBITDA represents net income (loss) before interest, taxes, depreciation, and amortization, adjusted to exclude the impact of specific items that are significant, but not reflective of the Company’s underlying operations, including impairment charges.

Non-GAAP Measure - Free Cash Flow

The Company uses free cash flow to supplement information in its consolidated financial statements. The most directly comparable financial measures prepared in accordance with GAAP is Cash provided by (used in) operating activities. The Company believes that in addition to conventional measures prepared in accordance with U.S. GAAP, certain investors and analysts use this information to evaluate the ability of the Company to generate cash flow after capital investments and build the Company’s cash resources. The Company calculates free cash flow by deducting cash capital spending from cash generated by operating activities. The Company does not deduct payments made for business acquisitions.

The following table provides a reconciliation of Cash provided by operating activities to free cash flow:
