(All amounts in U.S. dollars unless otherwise indicated)

Toronto, Ontario--(Newsfile Corp. - May 12, 2026) - Andean Precious Metals Corp. (TSX: APM) (OTCQX: ANPMF) ("Andean" or the "Company") is pleased to report its financial results for the three months ended March 31, 2026. This news release should be read together with Andean's management's discussion and analysis ("MD&A") and condensed interim consolidated financial statements for the three months ended March 31, 2026 (the "Financial Statements") which are available under the Company's profile on SEDAR+ (www.sedarplus.ca).

Alberto Morales, Executive Chairman and CEO stated: "We delivered a strong start to 2026, highlighted by record financial results driven by higher realized gold and silver prices and increased production across both operations.

At San Bartolome, we saw a meaningful step change in margin performance, with CGOM increasing to $36 per ounce and GMR exceeding 45%, reflecting the strong margin profile of our business in a higher silver price environment.

At Golden Queen, operations performed in line with expectations with first quarter sustaining capital coming in below our guidance; however, we anticipate sustaining capital to increase and finish the year in line with our 2026 CAPEX guidance.

We also reiterate our full-year 2026 production and cost guidance and remain focused on disciplined execution and free cash flow generation. We will continue to closely monitor geopolitical events and their impact on commodity prices and monetary policies.

Importantly, we ended the quarter with over $200 million in liquid assets, reflecting strong cash flow generation and providing us with significant flexibility to fund growth initiatives, advance exploration and evaluate strategic opportunities.

During the quarter, we also advanced key corporate initiatives, including increasing our public float through a non-dilutive secondary offering and progressing our application to list on the New York Stock Exchange. Together with the appointment of Victor Flores to lead exploration, operations and growth, these steps position the Company well to continue executing on our strategy and delivering long-term value to shareholders."

NON-GAAP FINANCIAL MEASURES, RATIOS, AND SUPPLEMENTARY FINANCIAL MEASURES

This news release includes "specified financial measures" within the meaning of National Instrument 52-112 - Non-GAAP and Other Financial Measures Disclosure ("NI 52-112"), specifically the non-GAAP financial measures, non-GAAP ratios and supplementary financial measures described below. Management believes that the use of these measures assists analysts, investors and other stakeholders of the Company in understanding the costs associated with producing silver and gold, understanding the economics of silver and gold mining, assessing operating performance, the Company's ability to generate free cash flow from current operations, and for planning and forecasting of future periods.

The specified financial measures used in this news release do not have any standardized meaning prescribed by IFRS and may not be comparable to similar measures presented by other issuers, even as compared to other issuers who may be applying the World Gold Council ("WGC") guidelines. Accordingly, these 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 IFRS.

Operating Cash Costs

OCC includes total production cash costs incurred at the Company's mining operations, which form the basis of the Company's cash costs, less by-product revenue.

Beginning in 2025 with impact on prior-year comparative periods, the Company reclassed mine-site general and administrative expenses to operating expenses which has a corresponding impact on the calculation of OCC.

The following table provides a reconciliation of the OCC per ounce sold on a by-product basis to the Financial Statements:

All-in Sustaining Costs

AISC on a by-product basis per ounce is a non-GAAP ratio calculated as AISC on a by-product basis divided by ounces of gold sold. AISC on a by-product basis is a non-GAAP financial measure calculated as the aggregate of production costs as recorded in the consolidated statements of income (loss), refining and transport costs, cash component of sustaining capital expenditures, lease payments related to sustaining assets, corporate general and administrative expenses and accretion expenses. When calculating AISC on a by-product basis, all revenue received from the sale silver at Golden Queen are treated as a reduction of costs incurred. The Company believes that AISC represents the total costs of producing gold from current operations and provides the Company and other stakeholders of the Company with additional information relating to the Company's operational performance and ability to generate cash flow.

The following table provides a reconciliation of the AISC per ounce sold on a by-product basis to the Financial Statements:

Cash Gross Operating Margin

CGOM per silver equivalent ounce sold is calculated by subtracting the average cash cost of sale (operating expenses, allocated corporate administrative costs and business unit general and administration cost) per equivalent ounce sold from the average selling price per equivalent ounce. It is a measure of financial performance with no prescribed definition under IFRS and may not be comparable to similar financial measures disclosed by other issuers.

The following table provides a reconciliation of the CGOM per ounce to the Financial Statements and the most directly comparable IFRS measure:

Gross Margin Ratio

GMR is calculated by subtracting the cost of sale as reported in the income statement from the revenue of equivalent ounces divided by revenue from sales of silver equivalent ounces. GMR is a measure of financial performance with no prescribed definition under IFRS and may not be comparable to similar financial measures disclosed by other issuers.

Beginning in 2025 with impact on prior-year comparative periods, the Company reclassed mine-site general and administrative expenses to cost of sales which has a corresponding impact on the calculation of GMR.

The following table provides a reconciliation of the GMR per ounce to the most directly comparable IFRS measure:

Free Cash Flow

The Company has included free cash flow as a non-GAAP financial measure in this news release. The Company considers net cash provided from operating activities, less capital expenditures on property, plant and equipment, to be a measure that allows the Company and investors to evaluate the ability of the Company to generate cash flow. Accordingly, free cash flow is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.

The following table provides a reconciliation of free cash flow to the Financial Statements:

Adjusted EBITDA

EBITDA and Adjusted EBITDA are non-GAAP financial measure calculated by adjusting net income (loss) as recorded in the condensed interim consolidated statements of income (loss) for items not associated with ongoing operations. The Company believes that this generally accepted industry measure allows the evaluation of the results of income-generating capabilities and is useful in making comparisons between periods. This measure adjusts for the impact of items not associated with ongoing operations. Management uses this measure to monitor and plan for the operating performance of the Company in conjunction with other data prepared in accordance with IFRS.

The following table provides a reconciliation of EBITDA and Adjusted EBITDA to the Financial Statements:

Average Realized Gold and Silver Prices Per Ounce

The Company has included average realized prices as a supplementary non-GAAP financial measure in this news release. The Company quantifies average realized price per ounce as revenue per the Statement of Income (loss), bifurcated by gold or silver revenue and divided by ounces of gold or silver sold, respectively. Management uses this measure to monitor sales of silver and gold ounces against the average market silver and gold prices.

The following table provides a reconciliation of average realized prices to the most directly comparable IFRS measure:

Liquid Assets

The Company believes this non-GAAP financial performance measure provides further transparency and assists analysts, investors, and other stakeholders of the Company in assessing the Company's financial position.

The following table provides a reconciliation of this non-GAAP financial metric to the Financial Statements:

CAPEX

The Company believes this non-GAAP financial performance measure provides further transparency and assists analysts, investors, and other stakeholders of the Company in assessing the Company's all-in cost of production costs which includes capital expenditures.

ENDNOTES

(1) Average realized gold price, average realized silver price, OCC, AISC, CGOM, GMR, Free Cash Flow, EBITDA, Adjusted EBITDA, Liquid Assets, and CAPEX are non-IFRS financial performance measures with no standardized definition under IFRS and may not be comparable to similar measures disclosed by other issuers. Refer to the "Non-IFRS Financial Measures, Ratios and Supplementary Financial Measures" section of this news release for further information, including a reconciliation of these measures to the Company's financial statements.

(2) Effective January 1, 2025, gold equivalent ounces are calculated by applying the ratio of the prevailing silver price to the prevailing gold price to silver ounces produced or sold in the applicable period. For 2025, the Company applied a conversion factor of 90. For 2026, the Company has updated its conversion factor to 85, reflecting current market price assumptions. This change has been applied on a prospective basis.

(3) Effective Q3 2025, the Company revised its methodology for reporting CAPEX to a cash flow basis, consistent with expenditures on property, plant and equipment as reported in the statement of cash flows. This change aligns the Company's CAPEX reporting with industry practice and peer disclosure and has been applied retrospectively to all prior-period comparative figures.

(4) Effective January 1, 2026, the Company has revised its methodology for calculating mine site operating income, OCC, AISC, and CGOM on a retrospective basis to exclude the allocation of corporate general and administrative expenses from these metrics. Management believes this change better reflects the operating cost performance of each mine site on a standalone basis and improves comparability with industry peers. Prior period figures have been restated to conform with the current presentation. In addition, the Company now separately discloses a consolidated OCC and AISC metric that includes corporate G&A costs, providing investors with a consolidated view of the Company's cost structure on a per-ounce basis. Readers are encouraged to refer to both the site-level and consolidated metrics when evaluating the Company's overall cost performance. See the "Non-GAAP Financial Measures" section of this news release for further detail on the calculation and reconciliation of these metrics.

(5) In Q1 2025, the Company's revolving line of credit of $22.6 million represented a back-to-back facility secured by, and linked to, the Company's cash and investments. As a result, the outstanding balance was deducted from Liquid Assets in the reconciliation, as the facility did not represent incremental liquidity available to the Company, resulting in Liquid Assets of $75.7 million. In Q1 2026, the Company's revolving credit facility operates on a standalone basis, unlinked to any cash or investment balances. Accordingly, no deduction has been applied, and the full value of the Company's cash, marketable securities, and long-term investments of $204.1 million is reflected in the Liquid Assets measure.
