Aris Mining (ARIS) Q2 2026 earnings review
Massive CapEx Cycle Weighs on Sequentially Softer Margins
Aris Mining delivered a stable Q2 2026 operationally, producing 73.7 koz of gold. However, the financial narrative shifted: sequential profitability decelerated due to a drop in realized gold prices and a sharp spike in sustaining capital costs. Adjusted EBITDA fell to $179 million (from $212 million in Q1). Despite the margin compression, the balance sheet remains a fortress. The company leveraged its $426 million cash pile to fund a massive $121 million capital injection during the quarter, aggressively advancing the Marmato and Segovia expansions toward their critical late-2026 milestones without external dilution.
🐂 Bull Case
The company successfully absorbed a $121 million capital outlay in a single quarter while still ending with $426 million in cash. The Marmato CIP plant remains on schedule for Q4 2026 first gold.
Soto Norte environmental studies are nearing completion, and Toroparu's Prefeasibility Study remains on track for H2 2026, providing a clear line of sight to the 1-million-ounce long-term goal.
🐻 Bear Case
Owner-operated AISC at Segovia spiked 18% quarter-over-quarter to $1,767/oz, driven by heavy sustaining capital requirements for underground development.
As predicted by management in Q1, Segovia's stellar 12.41 g/t processed grade was unsustainable, dropping to 10.23 g/t in Q2. This volume drop offset throughput gains.
⚖️ Verdict: ⚪
Neutral. Management is executing flawlessly on construction timelines, but the sequential financial contraction highlights the vulnerability of cash flows during this high-spend, capital-intensive phase.
Key Themes
AISC Spike Contradicts 'Strong Performance' Narrative
While management led the release touting 'strong H1 performance,' the underlying unit economics reversed direction. Segovia's Owner Mining AISC jumped from $1,492/oz in Q1 to $1,767/oz in Q2. This 18% cost inflation was driven by increased sustaining capital needed to prep the underground mine for the new 3,000 tpd plant. While necessary for future growth, it severely compressed near-term margins.
Macro Tailwind Flattens: Realized Gold Price Drops
The company faced a reversing macro tailwind. After peaking in Q1 2026, Segovia's average realized gold price fell 8% sequentially from $4,898/oz to $4,489/oz. This single factor was the primary culprit behind Adjusted EBITDA falling from $212 million to $179 million. If gold prices consolidate here, the company will have to rely purely on volume growth to expand earnings.
Marmato Construction Entering Final Phase
Capital deployment is accelerating exactly as planned. The company pushed $78 million into Marmato during Q2 alone. With the underground connection to the Bulk Mining Zone complete and major mills already on site, the 5,000 tpd CIP plant remains firmly on track for Q4 2026 first gold. This is the company's most important near-term catalyst.
Segovia Underground Haulage Advancing
To feed the newly expanded 3,000 tpd mill at Segovia, the bottleneck is moving rock out of the ground. Aris invested $31 million in Q2 to build a main underground haulage circuit connecting El Silencio, Providencia, and Sandra K mines. Tonnes processed increased 15% sequentially, proving the investments are starting to yield volumetric leverage.
Free Cash Flow Turns Negative Amid Heavy Investment
Reversing trend: the company's aggressive growth finally outpaced its operating cash generation. Adjusted net cash from operating activities fell to $83.5 million (from $116.2 million in Q1), while total capital additions spiked to $120.7 million. This resulted in a cash burn for the quarter, though the $426 million war chest makes this easily manageable.
Soto Norte Environmental Innovation
A key point of differentiation for the Soto Norte project is its processing design. Management highlighted that the project incorporates an industry-leading metallurgical process free of cyanide and mercury. As the company nears completion of the environmental license application for a Q2 2026 submission, this technological and environmental innovation will be crucial for securing local approval.
Contract Mining Partners Guarantee Output
The Contract Mining Partner (CMP) program continues to be a high-margin stabilization driver. CMP-sourced gold delivered an AISC sales margin of 46% in Q2, comfortably above the 35-40% full-year guidance. This flexible cost structure mitigates risk while the company develops its own owner-operated stopes.
Other KPIs
Decelerating from Q1's $212 million, though still significantly higher than Q2 2025's $98.7 million. The sequential drop was primarily driven by the lower realized gold price and increased unit costs at Segovia.
Down slightly from $472 million at the end of Q1, but represents immense liquidity. With the remaining net funding requirement for Marmato sitting at just $76 million (after the final Wheaton installment), the company is fully capitalized to execute its current pipeline.
Guidance
Stable. The company explicitly maintained this guidance. With H1 2026 production at 148 koz, achieving the midpoint (325 koz) implies H2 production of 177 koz. This requires a 19.6% sequential acceleration in the second half of the year, which management expects to deliver via Segovia's ramp-up.
Stable. Q2's print of $1,767/oz pushed the H1 average up to $1,623/oz. The guidance implies that the elevated sustaining capital investments seen in Q2 will likely persist through the remainder of the year to prepare the underground infrastructure.
Stable. H1 production was 17.1 koz. Hitting the upper end of this guidance explicitly assumes successful commissioning of the new CIP plant in Q4 2026; missing that timeline will likely peg production closer to the 35,000 oz bottom end.
Key Questions
AISC Trend Persistence
Owner mining AISC at Segovia spiked 18% sequentially due to underground development. Should we expect this elevated $1,700+ run-rate to be the new baseline until the 3,000 tpd mill is fully optimized in 2027?
Grade Normalization Curve
Segovia's processed grade normalized from 12.41 g/t to 10.23 g/t in Q2. As we push more volume through the plant in H2 to meet the implied production acceleration, will grades dilute further toward the 9-10 g/t reserve average?
Realized Pricing Dynamics
With the realized gold price dropping roughly $400/oz sequentially at Segovia despite spot prices remaining robust globally, are there any shifting dynamics in your off-take agreements or timing delays in sales settlements?
