Buenaventura's EBITDA Doubled and the Stock Fell 5%. That's the Disconnect.

The operating results are a step change - the market just isn't reading them that way.

Buenaventura's Q2 earnings call made the numbers unmistakable. Revenue hit $529 million, up 43% year over year. EBITDA from direct operations - the closest proxy to cash generated by the mining business before accounting charges - more than doubled to $277 million, up 113%. The EBITDA margin expanded from 35% to 52%. Net income attributable to owners jumped 160% to US$ 237.4M. And the stock fell 5% after earnings, with shares trading at $30.28 on July 31.

The sell-off had a headline reason: EPS of $0.93 missed the consensus estimate of $0.99. On the adjusted basis, EPS came in at $3.15 versus a $3.60 forecast. But you don't get 113% EBITDA growth and a 17-percentage-point margin expansion from a deteriorating business. The miss reflects timing and one-time ramp-up costs at San Gabriel, not weakening fundamentals. The market is applying a penalty for execution complexity without crediting the operating leverage that has already materialized across the rest of the portfolio.

For the first half of 2026 combined, revenue was up 70% year over year to $1.15 billion. First-half EBITDA from direct operations reached $663 million versus $256 million a year earlier. That is not incremental growth. That is a structural inflection driven by higher metal prices and production gains across gold, silver, and copper - all three moving higher simultaneously in the same quarter, which is rare for a diversified miner.

San Gabriel is the catalyst and the complication.

San Gabriel, Buenaventura's flagship gold development project, began commercial sales in Q2 and produced 2,800 ounces during the quarter. That's the catalyst. The complication is that the operation is nowhere near steady state.

Tailings-filtration issues are constraining throughput. The mill is operating at roughly 2,000 tonnes per day against a nameplate capacity of 3,000 tonnes per day. Management slashed the 2026 production guidance for San Gabriel in July from an initial range of 70,000–80,000 ounces down to 25,000–30,000 ounces. Gold recovery rates are being held back by organic matter and sulfides in the ore body. Management expects to spend $5–10 million reinforcing filter foundations and another $15 million on a new flotation circuit to push recovery toward 70% by year-end and 85% by the end of 2027.

This is a capital-intensive ramp-up. Unit costs at San Gabriel are not yet representative of steady-state economics. The additional $20–25 million in targeted capex is an investment to solve engineering problems, not a sign the project is broken. But it does mean gold production and cash flow from San Gabriel will take longer to normalize than early optimists - and some analysts - hoped.

Even if San Gabriel's ramp takes until mid-2027 to reach steady state, the rest of the business continues to generate substantial cash flow, and Cerro Verde provides a floor on the downside.

Cerro Verde is the quiet engine most investors overlook.

Buenaventura owns a 19.58% stake in Cerro Verde, the Freeport-McMoRan-operated copper-gold mine in southern Peru. The joint venture is a passive cash cow. Year-to-date in 2026, BVN has collected $274 million in dividends from Cerro Verde, with management expecting $350–380 million for the full year. That works out to roughly $35–40 million per quarter in unlevered cash flow that requires no operational effort from BVN and is insulated from the company's own execution risk.

Cerro Verde is expected to produce roughly 370,000–380,000 tonnes of copper in 2026. Dividends in 2027 are likely to remain in the $300 million range. That dividend stream alone covers a significant portion of BVN's capital spending and shareholder returns.

The balance sheet is an advantage, not a constraint.

Buenaventura ended Q2 with $759 million in cash and $692 million in total debt, leaving a net cash position of $67 million. Net debt to EBITDA sits at negative 0.05x. The current ratio stands at 2.0 and the quick ratio at 1.88. Total equity is $4.27 billion.

Full-year 2026 capex guidance is approximately $500 million. BVN spent $200–220 million in the first half and plans roughly $60 million for San Gabriel in the second half, plus an additional $12 million set aside to mitigate potential El Niño-related disruptions. Free cash flow over the trailing twelve months was $104 million, down nearly 30% year over year - but that decline is entirely driven by elevated capex on San Gabriel and Yumpag improvements, not by weaker operations.

There is no distress risk here. The company can fund its growth projects, maintain its dividend, and weather commodity volatility without borrowing more.

Yumpag adds another growth layer.

Separate from San Gabriel, Yumpag received regulatory approval in July to increase mining throughput from 1,000 to 1,200 tonnes per day. That change is expected to lift silver production by roughly 10% for the remainder of 2026 and reduce unit costs by 15–17%, aided by a grid connection scheduled for the fourth quarter. Yumpag is lower-hanging fruit growth - no major engineering problems, just incremental production and cost improvement that flows directly into margins.

So what does the valuation actually say?

BVN trades at a trailing P/E of roughly 9.8, an EV/EBITDA of 11.3, and a price-to-book of 1.8. The PEG ratio - which adjusts the P/E for the company's revenue growth rate - sits at 0.10. With revenue growth near 50% and EBITDA growth exceeding 100%, that multiple implies the market is pricing the stock as if future growth will be minimal.

The dividend yield stands at 3.6% on a trailing basis with a payout ratio of just 14%. That means the dividend is heavily cushioned by earnings and has substantial room to grow.

Relative to major gold miners, BVN's multiples look compressed. Agnico Eagle Mines trades at 12.5 times trailing earnings and 6.7 times EV/EBITDA. Wheaton Precious Metals trades at 27.5 times earnings and 25.1 times EV/EBITDA. BVN sits below both on the P/E and trades at a middle-ground EV/EBITDA - while growing revenue at a pace neither peer can match. The discount reflects small-cap illiquidity, Peruvian political risk, and the San Gabriel execution question. Those are real factors, but none of them invalidates the operating improvement.

The risk scan.

The primary risk is San Gabriel's ramp-up trajectory. If tailings-filtration and recovery problems persist beyond mid-2027, the additional capex burns cash without delivering proportional production. The secondary risk is commodity price exposure. BVN is a commodity producer, not a fee-based operator. A meaningful decline in gold or silver prices would compress EBITDA and margins - though the Cerro Verde dividends and net cash position provide a buffer. A tertiary risk is El Niño, which can disrupt operations in Peru through heavy rainfall and flooding. Management has allocated $12 million for preparedness, but that only mitigates, not eliminates, the threat.

Even if San Gabriel underperforms expectations and metal prices soften, the Cerro Verde dividend floor, net cash balance, and strong margin profile at the existing mine portfolio make a value-trap scenario unlikely. The business generated $577 million in operating cash flow over the trailing twelve months against a $7.7 billion market cap. That is not a fragile operation.

All things considered.

Buenaventura is a company whose EBITDA more than doubled, whose margins expanded by 17 percentage points, and whose balance sheet sits in net cash territory - and the stock sold off because adjusted EPS missed by $0.45 on one-time ramp-up costs. The market is reading this quarter backward.

The San Gabriel delays are real and deserve a discount, but the discount is already in the price. The stock trades at 9.8 times earnings, below slower-growing gold peers, with a dividend yield of 3.6% that represents barely 14% of earnings. The Cerro Verde dividends provide a $350–380 million annual cash floor. The company has the balance sheet flexibility to fund growth while maintaining returns.

BVN remains deeply undervalued relative to its cash-flow trajectory and peer set. I reaffirm my Strong Buy rating.
