AMEREN Q1 FY26 earnings call AEE

Ameren reported Q1 2026 EPS of $1.28 versus $1.07 in Q1 2025, a $0.21 YoY increase attributed to increased infrastructure investments across all operating segments. Management reaffirmed the 2026 EPS guidance range of $5.25 to $5.45. The primary offset in the quarter was warmer-than-normal winter temperatures that depressed Ameren Missouri electric retail sales, versus a colder-than-normal Q1 2025. Management flagged disciplined cost management but signaled higher tree-trimming costs in 2026, particularly in Q2, following a 2H 2025 ramp in reliability-focused energy-center and tree-trimming spend.

Ameren has 3.4 GW of construction agreements in Missouri and 850 MW in Illinois. In February it converted 2.2 GW of the Missouri agreements into signed ESAs, whose sites are secured and which are expected to move to groundbreakings and construction in Q2 2026. Management is optimistic about converting a portion of the remaining 1.2 GW of Missouri construction agreements to additional ESAs in the near term, and reported several additional gigawatts in each state at the engineering-study stage. The 2.2 GW of ESAs represents upside to the 6.2% base sales CAGR to the extent ramps outpace the 1.2 GW-by-2030 plan assumption. Costs to serve large-load customers are to be borne by those counterparties under Missouri Senate Bill 4 and the associated tariff.

Ameren is executing on more than 5 GW of new energy and capacity resources planned into service through 2030. The 50-MW Bowling Green Energy Center went into service in March, and the 300-MW Split Rail Energy Center began final commissioning (together able to power more than 63,000 homes). Two 800-MW simple cycle gas plants — Castle Bluff (2027) and Big Hollow (2028, with 400 MW of co-located battery storage) — are advancing; Castle Bluff received the first of four gas turbines ahead of schedule. A stipulation was reached in March for the 250-MW Reform Energy Center (in service 2028, pending Missouri PSC approval). Ameren expects to file additional CCN requests for roughly 3 GW by Q3, primarily the 2.1 GW West Alton combined cycle facility (planned 2031, Mitsubishi power-island equipment contracted) plus additional battery storage. Existing-fleet work includes up to 700 MW of cold-day capacity at the Adair Energy Center and boiler enhancements at Labadie.

Infrastructure investments and grid automation limited customer impact through multiple severe-weather events in Q1. During January winter storm Fern, the generation fleet performed under extreme conditions and the Ameren Illinois gas storage portfolio shielded customers from extreme market prices, saving about $63 million. In March, the company avoided 4.3 million outage minutes for nearly 20,000 Missouri customers, and during late-April storms system automation avoided an additional 43,000 customer outages and 12 million outage minutes over a two-day period, cutting overall customer impact by nearly half. Ameren also connected customers with more than $40 million in energy-assistance and weatherization resources in Q1.

Ameren continues to execute awarded long-range transmission projects from the first two MISO tranches while advancing competitive opportunities under tranche 2.1. In January it submitted joint bids for two competitive projects in Illinois (MISO developer selection expected by mid-2026) and is evaluating two additional competitive opportunities with bids due by end of May. Management framed transmission as a further source of upside alongside large-load-driven generation, noting it has historically excluded projects from capital plans until timing, scope and customer need are clear — leaving room for incremental transmission investment tied to interconnecting new large loads and generators.

Ameren completed its planned Q1 debt issuances at Ameren Missouri and Ameren Parent. It is progressing on approximately $4 billion of equity issuance for 2026-2030: last May it sold forward ~$600 million (about 6.4 million shares) to satisfy 2026 needs, expected to be issued near year-end, and so far in 2026 has sold forward another ~$600 million under its ATM program for 2027 and beyond. Following annual rating-agency meetings, S&P affirmed a BBB+ rating with stable outlook in April; Moody's annual opinion update is expected in the coming weeks.
