Ivanhoe's Q2 Showed $152M of Kamoa-Kakula EBITDA-Now the Smelter and Zinc Records Matter More

Kamoa-Kakula's Q2 EBITDA gives the bull case real operating substance

The clearest takeaway from Ivanhoe's second quarter is that this is no longer just a future-growth story. The headline number is $152M of attributable EBITDA from Kamoa-Kakula, within $179M of adjusted EBITDA for the group. That points to current operating strength rather than a speculative promise, with copper and zinc output plus smelter-related by-product credits helping drive the result.

Why the smelter matters more now

The smelter is the part investors should focus on. In Q2, smelter operating costs offset by high-strength sulphuric acid sales during Q2 2026, while acid production averaged 1,250+ tonnes per day. If that setup holds, Ivanhoe has a clearer path to better copper economics because lower logistics costs and valuable acid sales can help offset processing expenses.

Why this quarter matters

This is also the quarter that followed Q1 2026 loss of $2M and adjusted EBITDA of $191M, including $158M of attributable EBITDA from Kamoa-Kakula, making Q2 look less like a one-off headline and more like part of a broader operating improvement. Management has also tightened 2026 production guidance to 290,000 to 310,000 tonnes of copper, and Kipushi produced a record 70,177 tonnes of zinc in concentrate in Q2 2026. The message is simple: the current cash-generation story is becoming easier to verify.

The operating proof is in the smelter economics and Kipushi output

The key question is no longer whether Ivanhoe has strong assets. It is whether the smelter and zinc operations are improving margins in a repeatable way.

How the smelter changes the margin math

The mechanism is straightforward. In Q1, Kamoa-Kakula's margins were helped by sulphuric acid sales and significantly lower logistics costs, while acid production averaged 1,350 tonnes per day at $725 per tonne. By Q2, acid production was still strong at 1,250+ tonnes per day, Q3 contract prices up >100% this year to ~$840 per tonne, and the smelter's operating costs were being offset by acid sales. That does not prove a permanent margin expansion on its own, but it does show a real operating lever rather than a theoretical one.

Kipushi is supporting the portfolio too

Kipushi is not a distraction; it is adding meaningful zinc output at useful economics. In Q2, it produced record 70,177 tonnes of zinc in Q2 2026, at a cost of sales of $1.06/lb. and a cash cost (C1) of $0.90/lb., while zinc prices were $1.60/lb. of zinc. That spread reinforces the idea that Ivanhoe's near-term earnings are not dependent on copper doing all the work.

What could challenge the Q2 optimism

The main caution is that one strong quarter still does not settle the case. Copper production in Q2 was 64,328 tonnes of copper, and management's outlook still depends on higher H2 output, including a 30% increase in Kamoa mining rate to 8.5 Mtpa. If that increase translates into actual production and earnings persistence, the bullish case gets stronger. If not, the market may treat Q2 as a good quarter rather than a new baseline.

What would justify a durability re-rating

The most useful new proof is simple: management reported Q2 2026 profit of $46M. That matters because profit is easier to compare and underwrite than production headlines alone. Paired with Q1 2026 adjusted EBITDA of $191M, including $158M of attributable EBITDA from Kamoa-Kakula, the portfolio is starting to look less like a story stock and more like an operating platform with current cash generation.

Bull-case checkmarks

• Earnings persistence: The next few quarters need to show that profit and cash flow can hold up, not just one strong Q2.
• Smelter economics: Investors should watch for acid sales to keep helping offset smelter costs, with production staying near 1,250+ tonnes per day.
• Infrastructure and efficiency: The solar facility with battery backup is expected to reach full capacity by end of Q3 2026, which could support operational resilience.
• Production catch-up: Management expects H2 2026 Kamoa-Kakula copper production rates set to increase, and the Project 95 complete upgrade could add another operating lever.

Bear-case checkmarks

• No repeat, no re-rating: If subsequent updates do not show similar margin support from acid sales or similar zinc output, investors should treat Q2 as a strong data point rather than a durable pattern.
• Execution risk: Any slippage in mining-rate increases or recovery upgrades would make the re-rating case less urgent.

How to frame the setup

This looks more like a near-term operating story than a distant development story. If the next few releases show repeatable profit, stable smelter economics, and stronger copper output, Ivanhoe has a credible case for a durability re-rating. If those signals fade, the setup probably needs more time.
