Buenaventura Announces First Quarter Results

Compañia de Minas Buenaventura S.A.A. ("Buenaventura" or "the Company") (NYSE: BVN; Lima Stock Exchange: BUE.LM), Peru's largest publicly-traded precious metals mining company, today announced results for the first quarter (1Q26) ended March 31, 2026. All figures have been prepared in accordance with IFRS (International Financial Reporting Standards) on a non-GAAP basis and are stated in U.S. dollars (US$).

First Quarter 2026 Highlights:

• Gold production increased by 8% year-over-year (YoY) primarily driven by the ramp-up of operations at San Gabriel. Consolidated silver production increased by 6% YoY, reflecting higher output at El Brocal, Uchucchacua and Tambomayo. Lead and zinc production increased by 20% and 27% YoY, respectively, primarily due to higher throughput at Uchucchacua. Copper production decreased by 11% YoY, primarily due to lower output at El Brocal. This reflects the mine plan for 1Q26, which prioritized the processing of previously classified as low grade lead-silver ore, resulting in reduced copper ore throughput.
• EBITDA from direct operations was US$ 386.3 million, compared to US$ 126.3 million reported in 1Q25.
• Net income was US$ 355.2 million, compared to US$ 147.0 million net income in 1Q25.
• Capital expenditures (CAPEX) related to San Gabriel totaled US$49.2 million in 1Q26, primarily allocated to the completion of the processing plant. San Gabriel entered the ramp-up phase during the quarter.
• Buenaventura's cash position totaled US$ 759.9 million as of March 31, 2026. The Company reported a net cash position, with net debt of negative US$51.9 million, equivalent to a leverage ratio of -0.05x.
• On April 24, 2026, subsequent to the quarter's end, Buenaventura received US $58.7 million in dividends related to its stake in Cerro Verde. Total dividends received year-to-date 2026 amounted to US$156.6 million.
