SOTKAMO SILVER AB: INSIDER INFORMATION, PROFIT WARNING. SILVER PRODUCTION AND EBITDA MARGIN TO BE LOWER THAN EXPECTED IN 2025

Sotkamo Silver AB’s silver production for 2025 is expected to fall below the lower end of the previously estimated production guidance. This is due to lower-than-expected mining volumes and silver grade. As a result, the EBITDA margin is also expected to fall short of the guidance.

The company’s production volumes were weaker than anticipated in the early part of the year, due to factors such as insufficient mining capacity and technical challenges in the mining. Production volumes improved from the first half of the year, but not entirely in line with our expectations. A new mining contractor will start on January 1, 2026, which we believe will increase confidence in achieving mining targets.

The new guidance for year 2025 given 21 November 2025:

• The Company expects to produce 0.8 -0.9 million ounces of silver
• The Company expects annual EBITDA margin to be 16%
• The Company expects net debt-to-EBITDA to be below 2.5 at year-end

The Company's profitability is significantly affected by external factors, such as metal prices and exchange rates and internal factors like uncertainties related to ore volumes and metal grades. The achievement of the guidance assumes that metal prices and EUR/USD rate stay approximately at the current level of the time when the guidance was published (21 November 2025).

The old guidance given 31 July 2025:

• The Company expects to produce 1.0 -1.2 million ounces of silver
• Annual EBITDA margin to be at least 22%
• Net debt-to-EBITDA to be below 2.5 at year-end

The Company's profitability is significantly affected by external factors, such as metal prices and exchange rates and internal factors like uncertainties related to ore volumes and metal grades. The achievement of the guidance assumes that metal prices and EUR/USD rate stay approximately at the current level of the time when the guidance was published (31 July 2025).
