Buenaventura Mining Co (NYSE: BVN) reported second-quarter earnings per share (EPS) of $0.93, missing the analyst consensus estimate of $1.03 by 9.71 percent. However, the company’s quarterly sales reached $529.000 million, significantly beating the analyst consensus estimate of $118.442 million by 346.63 percent. This revenue figure represents a 43.17 percent increase over sales of $369.500 million in the same period last year.

The earnings miss occurred despite a strong operational performance, with net income attributable to owners of the parent reaching US$237.4 million, a 160% year-over-year increase from US$91.3 million in 2Q25. The divergence between the missed EPS estimate and the substantial revenue beat highlights the impact of cost structures and affiliate contributions on bottom-line profitability relative to market expectations.

Operational Drivers and Production

The 43% rise in total revenues was underpinned by increased gold production and the commencement of sales volumes from its San Gabriel operation. Gold production increased by 12% year-over-year, primarily due to the ramp-up at San Gabriel. Consolidated silver production grew by 2%, reflecting higher output at Yumpag. However, lead and zinc production declined by 19% and 5% respectively, attributed to lower grades at Tambomayo. Copper production remained stable, increasing by 2% year-over-year.

San Gabriel continued its ramp-up during the quarter, though processed tonnage was constrained by tailings-management challenges, particularly at the tailings filtration plant. Subsequent to quarter-end, on July 10, 2026, Buenaventura received approval to increase the mining rate at Yumpag from 1,000 to 1,200 tonnes per day.

Financial Position and Analyst Estimates

Buenaventura maintained a strong balance sheet, with a cash position of US$758.9 million as of June 30, 2026. The company reported net debt of negative US$66.6 million, indicating a net cash position. On July 24, 2026, following the quarter-end, Buenaventura received US$117.5 million in dividends from its ownership interest in Cerro Verde.

Figures in millions of US$, excluding EPS.

What the Numbers Show

The significant beat on sales estimates ($529.0M vs $118.4M) suggests that analysts may have underestimated the immediate revenue contribution from the San Gabriel ramp-up or metal price realizations. However, the EPS miss indicates that operating costs or non-operating expenses were higher than anticipated, offsetting the top-line strength. The inclusion of affiliate results, such as the Cerro Verde dividend, remains a critical component of the company’s cash flow profile, contributing to the overall EBITDA including affiliates which rose 105% to US$492.8 million.

Compañía de Minas Buenaventura S.A.A. reported gold production of 37,266 ounces for the second quarter ended June 30, 2026. The company revised its 2026 production guidance for several units, including Yumpag and San Gabriel, to reflect updated operational constraints and grade profiles.

Production and Sales

Total gold production, including associated companies, reached 37,266 ounces for the three months ended June 30, 2026, and 75,062 ounces for the six months ended June 30, 2026. Silver production totaled 3,523,749 ounces for the quarter and 7,233,076 ounces for the half-year. The company sold 33,092 gold ounces and 3,342,427 silver ounces during the second quarter.

Operational Updates

Buenaventura revised guidance for the Yumpag unit to reflect a stronger-than-expected grade profile, following silver production that exceeded projections in the second quarter. The company received approval in the third quarter to increase the mining rate to 1,200 tonnes per day from 1,000 tonnes per day.

At San Gabriel, the company revised guidance to account for tailings-management constraints and current metallurgical recovery rates. The unit continued its ramp-up during the quarter, with processed tonnage constrained by challenges at the tailings filtration plant. Sales volumes began recording in the second quarter.

Guidance for Orcopampa was revised to reflect higher grades in areas currently under development, as gold production slightly exceeded projections due to higher ore throughput. Tambomayo’s guidance was revised to reflect increased production volumes, supported by positive exploration results and the current commodity price environment, after silver production exceeded projections.

Average Realized Prices

Average realized prices for the three months ended June 30, 2026, were $4,342 per ounce for gold and $89.52 per ounce for silver. Lead and zinc realized prices were $1,852 and $3,451 per metric ton, respectively, while copper realized $14,029 per metric ton.
