Capstone Copper (TSX:CS) Could Be 35% Below Fair Value On Weaker Guidance

Capstone Copper (TSX:CS) has become a focus after third quarter results showed lower copper volumes and a sharp drop in quarterly net income, even as sales rose. Updated guidance points to production at the low end of its 2026 range.

The recent guidance update and weaker third quarter profitability come after a choppy stretch for Capstone Copper’s shares, with a 90 day share price return down 25.29% and a 1 month share price return down 14.35%, even though the 3 year total shareholder return is up 160.58%. This indicates that long term holders have still seen gains despite fading near term momentum around the CA$11.70 level.
