Arturo Prestamo, Executive Chairman and CEO of Santacruz, commented: 'Santacruz delivered a strong start to 2026, with revenue of $127.5 million, gross profit of $42.9 million and Adjusted EBITDA of $42.6 million, representing improvements of 81%, 54%, and 55%, respectively, compared to the same period last year. Combined with our stable AISC this quarter, the stronger silver price environment drove robust margins of $31.70 per silver ounce sold, a 221% increase year-over-year. This reinforces the strength of our cash flow generation across our operations, reflecting both a stronger commodity environment and the operating discipline we have embedded across every asset. It is also important to highlight that after paying $31.5 million in taxes during this first quarter, we ended Q1 2026 with a healthy cash and highly liquid marketable securities position of $64.9 million, providing Santacruz with the financial flexibility to continue funding operational improvements while maintaining a strong treasury position.'

Mr. Prestamo continued: 'During the quarter, we also introduced a more comprehensive reporting format designed to provide investors with a clearer view of our operating performance and the underlying strength of our business model. The new presentation better reflects Santacruz as a silver and zinc co-product producer, while separately highlighting San Lucas as a margin-based ore sourcing and processing business that supports plant utilization, fixed-cost absorption and operating flexibility. We believe this enhanced reporting framework provides a more complete basis for investors to assess production, costs, margins and cash generation across the Company.'

Mr. Prestamo added: 'Operationally, the first quarter demonstrated the strength of our diversified asset base and the benefits of our silver and zinc co-product profile. At Bolivar, the recovery of the areas affected by the May 2025 localized water inflow event continues to advance. We remain focused on restoring production while maintaining operating discipline, with Q4 2026 still targeted for Bolivar's full recovery. Across Bolivia, our priorities remain focused on operational stability, cost control and plant performance, with San Lucas continuing to play a strategic role in supporting plant utilization, fixed-cost absorption and margin contribution through third-party ore sourcing.'

Mr. Prestamo concluded: 'In Mexico, our principal focus remains on improving metallurgical recoveries and concentrate quality at Zimapan, our highest-volume operation. The capital already invested in Zimapan is expected to support continued operating improvements throughout 2026. Across all of our processing plants, we remain focused on improving metallurgical recoveries, generating stronger margins and preserving the flexibility of our integrated operating platform to support long-term value creation for shareholders.'

Update to Non-GAAP Performance Measures and Silver/Zinc Equivalent Ounces Metrics

In Q1 2026, the Company updated its non-GAAP performances measures to provide management and readers with useful information to evaluate the performance of the Company. The following section provides a summary of the changes made:

Segregation of mining operations & ore processing: Operational and cost metrics are now presented as either Mining operations or Ore processing operations because the underlying business processes and profitability drivers each type of operation are fundamentally different. Mining operations include the production metrics, revenues and costs from extracting ore from the Company's mineral properties which is then processed and sold in concentrate form. Santacruz's mining operations consist of the Bolivar, Porco, Caballo Blanco and Zimapan mines. Ore processing operations consist of the San Lucas feed sourcing business and includes the production metrics, revenue and costs from purchasing ore from third-party miners which is then processed and sold in concentrate form. Mining operations generate high margins because the input for the final product, metal concentrates, is from ore that is extracted from the Company's mine properties that it owns. Ore processing operations generate significantly lower margins because the ore is purchased from third-party miners and the amount paid for the purchased ore is based upon the ore's metal content and prevailing metal prices at the time of purchase.

Co-product costing methodology: The Company will no longer focus on costs per silver equivalent ounces sold and will now provide costs per actual silver ounce and zinc tonne sold in the period using a co-product cost methodology which allocates costs between each metal. The Santacruz's primary payable metals are silver and zinc, the revenue generated by each metal varies depending on prevailing metal prices but because each metal generates greater than 30% of the total revenues, the Company has concluded that reporting costs as co-products by silver ounce sold and zinc tonne sold is the most appropriate way to assess the performance of its operations. The total tonnes of ore milled in the period generates silver and zinc payable metals for sale, the ratio of payable silver and zinc produced from each tonne milled is used to allocate each period's production costs between silver ounces sold and zinc tonnes sold, which will generate the following metrics: cash cost per silver ounce and zinc tonne sold, all-in sustaining cost ('AISC') per silver ounce and zinc tonne sold and will also provide an average realized price per silver ounce and zinc tonne sold.

By-product credits from secondary metal sales: Santacruz's operations are poly-metallic whereby each tonne of ore milled generates primarily payable ounces of silver and tonnes of zinc but also generates payable tonnes of lead and copper. The combined revenues of lead and copper are incidental to the Company's primary metal production of silver and zinc because they generate less than 10% of total revenues. Lead and copper concentrate is produced primarily to obtain the silver contained within, so the Company has adopted the practice of calculating the net cost of producing an ounce of silver, after deducting revenues gained from incidental by-product production of lead and copper.

Realized mining margin and realized ore processing margin: Santacruz has created two new non-GAAP measures: the realized mining margin and realized ore processing margin. Management believes the margins are an effective way to evaluate the profitability of the Company's operations. The margin is calculated by subtracting the all-in sustaining cost per silver ounce or zinc tonne sold from the average realized price per silver ounce or zinc tonne sold.

Silver equivalent ounces and Zinc equivalent tonnes: Commencing Q1 2026, the Company has modified its production disclosure to include zinc equivalent tonnes produced and has updated the method of calculating silver equivalent ounces produced. The Company considers silver equivalent ('AgEq') ounces and zinc equivalent ('ZnEq') tonnes to be useful production metrics for evaluating its multi-metal production profile, but they should be considered only supplemental to the actual production volumes of silver and zinc produced and sold. The Company will continue to present the silver equivalent ounces produced and zinc equivalent ounces produced for the combined mining and ore processing operations, but will no longer report its costs per silver ounce to focus on the more relevant metrics of cost per payable silver ounce and cost per payable zinc tonne sold instead.

As there are no standardized methods of calculating non-GAAP measures, the Company's methods may differ from those used by others and, accordingly, the Company's use of these measures may not be directly comparable to similarly titled measures used by others. Accordingly, these non-GAAP 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. Refer to the Non-GAAP Measures section in the Company's Q1 2026 MD&A for a detailed explanation of the metrics, the methodology used and a reconciliation of these measures to the Company's revenues and operating expenses, as reported in its condensed interim consolidated financial statements which are prepared under IFRS. All the changes made to the non-GAAP measures have been applied retrospectively to comparative periods.

Q1 2026 vs Q1 2025

Compared with Q1 2025, consolidated mining operations produced 1.0 million ounces of silver, a decrease of 23%. Including San Lucas's ore processing activities, total silver production decreased by 16% to 1.3 million ounces. The year-over-year decline was mainly attributable to lower silver production from mining operations, including the effect of lower silver output at Bolivar following the water inflow event that affected that operation toward the end of Q2 2025, as well as lower silver production at Zimapan and Caballo Blanco. This was partially mitigated by operational execution and ore processing activities, which continued to support consolidated metal production. Zinc production from mining operations was broadly stable, decreasing by 1% to 14,496 tonnes, while total zinc production, including ore processing, increased by 4% to 21,640 tonnes. This indicates that zinc output remained comparatively resilient at the consolidated level, supported by the broader contribution of the Company's operating platform.

From a financial contribution perspective, Santacruz generated positive unit margins for both silver and zinc in Q1 2026. The Average Realized Silver Price increased to $63.30 per ounce from $27.80 per ounce in Q1 2025, while silver AISC increased to $31.60 per ounce from $17.91 per ounce. As a result, the realized mining margin per silver ounce sold increased to $31.70 from $9.89, reflecting the strong increase in realized silver prices, which more than offset higher unit costs. For zinc, the Average Realized Price increased to $3,116 per tonne, while AISC increased to $2,729 per tonne. The resulting realized mining margin was $387 per tonne, compared with $718 per tonne in Q1 2025. Zinc therefore remained positive on a unit-margin basis, although the margin contracted year over year due to the increase in AISC. Overall, silver was the primary driver of improved consolidated unit-margin performance in Q1 2026, while zinc continued to contribute positively but at a lower margin than in the prior-year period.
