Lundin Mining Announces Updated Share Capital, Provides Update on Share Buybacks and Announces Filing of ESTMA Report
Lundin Mining Rallies on Vicuña Study as Copper Giant Eyes Top-Ten Status

Executive Summary
- Share Capital Update: Issued and outstanding shares decreased to 855,378,907 common shares as of May 29, 2026.
- Buyback Program Progress: Approximately US$51 million spent on share buybacks in 2026 against a US$150 million annual budget under the Normal Course Issuer Bid (NCIB).
- Regulatory Filing: Filed Extractive Sector Transparency Measures Act (ESTMA) Report for the year ended December 31, 2025.
- Share Count Drivers: Decrease attributed to NCIB buybacks offset by employee stock option exercises and share unit vesting.
Material Impact
- Routine Execution: The news confirms execution of a previously announced capital return policy ($150M annual budget). It does not introduce new strategic value or unexpected financial metrics.
- EPS Accretion: Reducing the share count by ~231,484 shares is marginally accretive to earnings per share but immaterial relative to the company's size and recent price appreciation.
- Market Context: The stock has already rallied significantly from $13 (May 2025) to over $41 (May 2026), driven by major catalysts earlier in the year (Vicuña PEA, Credit Facility Upsize, Eagle Sale). This update is consistent with prior expectations set in January and February.
- No Surprise: The buyback spend ($51M YTD) aligns with the timeline of a $150M annual budget; no acceleration or deceleration that would signal distress or aggressive capital allocation change.
