Second Quarter 2026 Highlights:

• Gold production increased by 12% year-over-year (YoY) primarily driven by the ramp-up at San Gabriel. Consolidated silver production increased by 2% YoY, primarily reflecting higher production at Yumpag. Lead and zinc production decreased by 19% and 5% YoY, respectively, primarily due to lower grades at Tambomayo. Copper production increased by 2% YoY, reflecting stable production at El Brocal.
• 2Q26 EBITDA from direct operations was US$ 277.1 million, compared with US$ 130.1 million reported in 2Q25. 6M26 EBITDA from direct operations was US$ 663.4 million, compared to US$ 256.4 million reported in the first six months of 2025.

• San Gabriel continued to ramp-up during 2Q26. During the quarter, processed tonnage was constrained by tailings-management challenges, particularly at the tailings filtration plant. The Company began reporting sales volumes from San Gabriel in 2Q26.
