First Majestic Surges 3.33% on 127.86% Volume Spike Ranked 487th as State Regulatory Shifts Unfold

On August 22, 2025, First Majestic (AG) rose 3.33% with a trading volume of $0.22 billion, marking a 127.86% surge from the previous day. The stock ranked 487th in volume among listed equities. The move followed developments in state-level legal and regulatory shifts, particularly in Michigan, Missouri, and South Carolina, which could influence the company’s operational landscape.

Missouri Governor Mike Kehoe appointed Catherine Hanaway as the state’s new Attorney General, effective September 8. Hanaway, a former U.S. Attorney and Missouri House Speaker, will succeed Andrew Bailey, who is leaving to join the FBI. This transition may reshape regulatory priorities in the state, potentially impacting businesses operating in Missouri. Meanwhile, Michigan Republican Matt DePerno re-entered the race for Michigan AG, joining a competitive primary field. South Carolina’s AG Alan Wilson, currently running for governor, has triggered a vacancy in his role, with David Pascoe and Stephen Goldfinch vying for the Republican nomination. These leadership changes could alter legal and policy environments in key markets for First.
