Alliant Energy Corporation (LNT) Income Statement

The revenue trajectory suggests growth is primarily driven by regulatory rate base additions and rate case outcomes rather than weather or volumetric demand. Quarterly growth has been uneven, ranging from 0.4% to 11.9% over the period, which may indicate dependence on the timing of individual rate case cycles. Investors should monitor whether this growth can be sustained once the current solar build-out enters a slower capital phase.

The wide margin band is difficult to reconcile with a steady authorized ROE, suggesting that reported quarterly earnings are heavily influenced by weather normalization, rate case timing, and deferral accounting. The Q2 2026 EPS of $0.65 against a much higher estimate further suggests that quarterly results may not reflect the underlying regulated earnings run-rate. Without disclosed earned-versus-authorized ROE data, the gap cannot be confirmed and warrants further investigation.

The rising depreciation load indicates that incremental capital is being placed in service, but EPS has not shown a consistent corresponding lift, which may reflect regulatory lag or construction work in progress not yet earning a return. Capital recovery therefore appears to depend on the timing of rate case approvals. Investors should monitor whether the renewable build-out converts into rate base growth at the pace implied by current capital spending.
