Key Metrics
Top Statement Risk
Leverage-driven refinancing exposure
Metrics are mathematically derived from official filings.
Rate Base Expanding Faster Than Equity
According to reported balance sheet figures, LNT's net PP&E grew from $17.7B to $21.6B over ten quarters, roughly 22%, while total equity rose only from $6.8B to $7.8B, a gap suggesting the regulated asset base is increasingly funded by debt.
The widening spread between PP&E growth and equity growth suggests the capital program relies heavily on external financing rather than retained earnings. For a regulated utility, this pattern is not inherently negative if rate recovery follows, but it shifts the risk toward timing mismatches between construction spending and rate case approvals. Investors should monitor whether authorized returns keep pace with the rising asset base.
Reported Leverage Requires Verification
Based on the reported figures, LNT's debt-to-equity ratio of 1.68 in 2025Q4 and total debt of $12.3B against $7.3B of equity point to a leverage profile that warrants verification against regulatory capital structure filings.
A reported debt-to-equity near 1.6 to 1.7 is consistent with a utility carrying substantial rate base financing, but the figures are not directly comparable to authorized debt-to-capital ratios set by commissions. The snapshot's reported D/E was flagged elsewhere as potentially understated, so the true regulatory leverage position cannot be confirmed from this data alone. Headroom under rate case parameters should be checked directly in commission filings.
Thin Cash Buffer Against Construction Needs
As reported in financial statements, LNT's cash balance fell to $25.0M in 2026Q2 and $26.0M in 2026Q3, while the current ratio ranged from 0.34 to 0.86 over the period, indicating minimal liquidity cushion.
Cash balances near zero combined with current ratios well below 1.0 suggest the company depends on revolver capacity and commercial paper access to fund operations and construction. The data does not disclose facility size or availability, so any conclusion about financing headroom would be inference. Investors should monitor short-term debt rates and revolver utilization in forthcoming filings.
Capex Lumpiness Obscures Recovery Timing
Based on LNT's reported capital expenditure, quarterly outflows swung between roughly $414M and $2.5B, including a $2.5B outlay in 2025Q4, a pattern that may reflect project milestones and makes near-term rate base additions difficult to forecast from these figures.
Irregular capex timing complicates the link between spending and eventual regulatory recovery, as recognition typically follows in-service dates rather than cash outlays. The reported figures do not disclose the specific rate case schedule or tracker mechanisms, so recovery protection cannot be assessed directly. Further investigation of commission filings is warranted before concluding on the timing of earnings benefits from current spending.
Leverage Could Constrain Future Growth
Based on reported figures, LNT's net debt to EBITDA of 6.1 and weak interest coverage may indicate that rising refinancing costs could pressure the capital program if rates remain elevated.
Net debt to EBITDA near 6 is elevated for a utility, and the interest burden of roughly $120M to $139M per quarter appears substantial relative to reported operating cash flow in several periods. This combination may limit flexibility to fund capex without additional equity or asset sales, though the data does not confirm such actions are planned. The most plausible risk is that refinancing at higher rates compresses the spread between allowed returns and financing costs.
