Why Alamos Gold Stock Is Plummeting Today

Alamos Gold (AGI) crashed 14.39% after the company slashed second-quarter 2026 production guidance to 130,000-135,000 ounces, a 12% reduction from prior estimates. The cut stems from seismic activity at its Young-Davidson mine in Ontario, forcing the miner to revise its full-year 2026 outlook downward while projecting costs above previous expectations.

Bank of America responded by dropping its price target on AGI from $57 to $50, adding sell-side pressure to the stock. The Young-Davidson disruption represents a material setback for a company that relies on consistent output to maintain margin profiles in a volatile gold price environment.

The seismic event introduces operational uncertainty beyond the immediate production miss. Mine stability issues can cascade into extended downtime, capital expenditure increases for ground support, and regulatory scrutiny that compounds production delays.
