Coeur Mining shares surge 12.16% after-hours as Glass Lewis backs New Gold merger.

Coeur Mining surged 12.16% in after-hours trading, driven by growing momentum around its proposed acquisition of New Gold. Key catalysts included endorsements from proxy advisory firms Glass Lewis and Institutional Shareholder Services (ISS), which recommended New Gold shareholders approve the deal, significantly boosting its likelihood of success. Strong third-quarter 2025 results, including a 76.9% revenue increase to $555 million and robust gold/silver production, further reinforced investor confidence. Exploration progress at the Rochester and Palmarejo sites added to optimism. The stock’s rally aligns with near-term catalysts, including the January 27, 2026, shareholder vote and Coeur CEO’s upcoming presentation at the TD Cowen Mining Conference.
