Ameren shares declined 2.6% after the quarter, reflecting investor caution despite steady execution, as the company did not update its sales growth forecast or materially advance large-load electric demand visibility, leaving growth drivers uncertain.

• Q1 earnings rose to $1.28 per share from $1.07 year-over-year, driven by infrastructure investments aimed at long-term benefits.
• Reaffirmed 2026 EPS guidance at $5.25 to $5.45 with no upward revision despite ongoing investments.
• Infrastructure investments totaled over $1.5 billion in Q1, enhancing grid reliability and reducing customer outages during severe weather events.
• Large-load demand via energy service agreements (ESAs) remains a growth opportunity but progress towards updating the sales forecast tied to these remains pending.
• Continued focus on cost allocation to large customers and maintaining a balanced generation portfolio amid an evolving demand base.
