Ero's Q2 Passed the Smell Test-But 2026 Only Works if H2 Repeats the Cash, Not Just the Gold Spike

Ero's Q2 looked solid, but durability is the real question

Ero's latest quarter passes the first test: core operations delivered. The company produced 17,315 tonnes of copper at $2.42 per pound C1 cash costs, while Xavantina generated 20,553 ounces of gold, up 170% quarter on quarter. That mix is why the call matters. Copper looked like a reliable operating base, while the gold surge raised a different question: how much of this quarter was repeatable mine performance, and how much was a temporary windfall from stockpiles?

The cash story was strong. Ero reported cash flow from operations of $137.9 million, up approximately 49% from the previous quarter, and adjusted EBITDA of $144.0 million, up approximately 15% quarter on quarter. Available liquidity increased by $35.5 million quarter on quarter to $181.7 million. The next updates matter because investors now need to see whether copper stayed firm, whether gold remained supportive, and whether those cash flows continued to strengthen the balance sheet.

If H2 looks like H1 because copper stays solid and Xavantina remains helpful without relying on the same stockpile tailwind, this quarter starts to look more durable. If the gold spike fades and the cash does not follow, then Q2 was a strong quarter rather than a new baseline.

Caraíba looked repeatable; Xavantina has two different drivers

The cleanest signal in the quarter was copper. Ero's Caraíba output and costs looked like the kind of performance that can support the business through normal commodity swings. The company also reaffirmed 2026 copper production and cost guidance, which matters because guidance holds up better when current operations are already backing it.

Xavantina, by contrast, had two distinct drivers that investors should keep separate.

The more durable part: mined gold and incremental mine improvement

Ero's mined gold production was 8,693 ounces at $1,586 C1 cash costs and $2,881 AISC. That is the part of the Xavantina story that looks more like a normal operating engine. It can improve over time as mining and processing get better, and it is easier to underwrite than one-off recoveries.

The less durable part: the stockpile catch-up

The second driver was much more favorable in Q2, but also less repeatable. Ero recovered 11,860 ounces of gold from historic gold concentrate stockpiles at just $633 C1 cash costs and $715 AISC. That is economically attractive, but it is not the same thing as building a higher-volume, lower-cost mine. Once that stockpile material is cleared, the quarter will not get the same cost benefit again.

That does not make Q2 weak. It just means 2026 should be modeled on copper as the backbone, with gold acting as a possible upside factor rather than a permanent discount engine.

What to watch in H2 to judge whether Q2 was durable

Management did not need to overstate the quarter. The release already showed strong operational execution across the portfolio, and the main job now is to see whether that execution persists.

Watch for:

• Copper stability: whether Caraíba continues to deliver close to Q2 levels and keeps the cost base under control.
• Cash generation: whether operating cash flow and liquidity remain healthy as the quarter's gains move into H2.
• Xavantina mix: whether mined gold holds up and whether recovered gold contributes less as the stockpile benefit runs its course.

If those signals hold, investors can start to treat Ero as a more durable cash generator. If the stockpile boost disappears and the cash weakens with it, Q2 was helpful, but not yet proof of a repeatable new phase.
