Ero Copper to Release First Quarter 2026 Operating and Financial Results on May 4, 2026

• The most recent release (2026-04-01) announces that Ero Copper will publish its First Quarter 2026 operating and financial results on May 4, 2026, after market close, with a conference call on May 5, 2026. The company provides the standard webcast access details and notes that the presentation will be available on the day of the call. No actual results or guidance are disclosed in this release.
• Context from the prior news flow shows a clear progression toward a significant growth narrative:
• 2026-02-23: Inaugural PEA for Furnas Copper-Gold Project released, highlighting a large-scale, long-life operation with a 24-year initial mine life, robust economics (NPV8% ~$2.0B, IRR ~27%), and ongoing earn-in discussions with Vale Base Metals to acquire 60% interest. This establishes Furnas as a cornerstone growth project.
• 2026-03-30: NI 43-101 technical report filing for Furnas deepens the disclosed economics, resources, and development plan supporting the earn-in and potential project advancement.
• 2026-02-05 and 2025-03/11: The company reported strong 2025 results with record copper production, cost metrics, and improved liquidity; guided 2026 production and highlighted Furnas as a key long-term growth driver alongside ongoing expansion at Caraíba, Tucumã, and Xavantina.
• In sum, the latest news is a scheduling update for upcoming results, which is a routine communications event and does not itself alter the company’s quantitative guidance or near-term financials. It sits within a broader framework of highly material Furnas-related developments that were previously announced (PEA and NI 43-101 disclosure) and ongoing operations progress at the company’s existing mines.

• Short-term fundamental impact: Neutral. The April 1 release does not adjust guidance, metrics, or capital plans; it simply schedules the Q1 2026 results. No new numbers or revisions are provided.
• Medium-term catalysts already embedded in the news flow:
• Furnas economics and earn-in economics are materially positive as established by the February 23 PEA and reinforced by the March 30 NI 43-101 report. These underpin a potential uplift in valuation if Furnas progresses toward a construction decision and enhanced capital efficiency via byproduct opportunities (magnetite, gravity pre-concentration).
• The company’s 2025 results highlighted improved leverage, strong cash flow, and a path to deleveraging with potential shareholder capital return once net debt/EBITDA approaches sub-1x. The April 1 scheduling news does not alter that trajectory.
• Stock price reaction risk: The market reaction to a results-date announcement is typically muted unless accompanied by new guidance or surprises. Given the absence of new data in the latest release, the immediate impact is likely modest and neutral.
• Fine print risks (hidden/ongoing): Furnas remains dependent on continue advancement under Vale Base Metals’ earn-in, regulatory permits, and the timeliness of exploration and feasibility work. The PEA assumptions (long-term prices, capital intensity) carry typical commodity and project development risks.

• Overview: Ero Copper is a diversified copper-focused producer with operations in Brazil (Caraíba, Tucumã, Xavantina) and a strategic long-term growth story tied to the Furnas Copper-Gold Project in Pará. The portfolio comprises copper-rich Caraíba and Tucumã, gold-rich Xavantina, and an earn-in pathway to Furnas with Vale Base Metals.
• Flagship project: Furnas Copper-Gold Project (Pará, Brazil). PEA released Feb 23, 2026, signaling a large-scale, long-life operation with initial mine life of ~24 years, robust economics (NPV8% ~$2B, IRR ~27%), and significant potential for byproduct revenue enhancements (magnetite circuit, gravity pre-concentration). Earn-in target: 60% interest through Vale Base Metals.
• Operational footprint (as of latest disclosures): Caraíba and Tucumã are producing; Xavantina is in production with gold concentrate sales; Furnas remains in evaluation/advanced study phases.
