Alamos Gold cuts Q2 output forecast to 130,000-135,000 oz, sees 2026 production below guidance range

• Alamos cut Q2 production guidance to 130,000-135,000 ounces, a 12% drop at the midpoint.
• Young-Davidson Q2 output expected near Q1 due to two seismic events that blocked higher-grade stopes, three days of outage downtime, lower mined grades.
• Young-Davidson mining rates forecast to average about 5,000 tonnes per day for the rest of 2026.
• Q2 costs now expected above prior guidance due to lower Young-Davidson production.
• Full-year 2026 consolidated production seen below the low end of guidance, with costs above guidance; updated targets due with late-July results.
