Alliant Energy (LNT): analysis traps

Where its figures could mislead a reader, and what to check before taking them at face value · Data: Q3 2026, to Sep 30, 2026, filed Oct 30, 2026; rules v1.1

Alliant Energy (LNT): 0 rules of 10 triggered on the filings to Sep 30, 2026. 1 to review; 1 with insufficient data; 2 not applicable. Each is a question to verify, with the normal explanation that would produce the same figures.

Check these first

A precise DCF value = the true value To review · confidence high

The DCF's point value is 67.25 a share (price 72.67); 67% of it is the terminal value, a number about years no one has seen. Moving wacc by ±1 pt alone takes it from 48.73 to 97.81; across every method the research ran the range is 21 to 202. The value is a range; the decimals are not information.

Innocent reading: A stable, mature business with a narrow range of outcomes, where the point value is a fair summary.

Every rule

A01 FCF growth = the business improved Not triggered confidence high

Free cash flow did not rise (−$885M → −$1.1B): the trap does not arise.

FCF = operating cash flow − cash capex; ΔFCF = ΔOCF − ΔCapEx; the working-capital part is the change in the cash-bridge items (receivables, inventory, payables, accruals), with the sign of the cash flow statement

A07 Stock compensation added back = no economic cost Not triggered confidence high

Stock compensation is 0.5% of revenue: small enough that adding it back changes little.

B02 Receivables growing = future cash is certain Not triggered confidence medium

Receivables grew 38% against revenue 5% in Q1 2026; DSO 37 against a median of 42: collections are keeping pace with sales.

B08 Adjusted profit = economic profit Insufficient data

no reconciliation table read from the releases yet and fewer than three quarters with both an adjusted and a GAAP EPS

C02 Low net debt = no refinancing risk Not triggered confidence medium

$1.1B comes due within a year, 1.5× covered by cash and investments of $365M plus $1.3B of free cash flow.

E02 Low P/E at a cyclical peak = undervalued Not triggered confidence medium

Net income of $821M is not at a cyclical high against the last eight years (median $686M, best $810M): the P/E of 22.9× is on a normal year.

What would explain it innocently

What to look for in the filing

What would show the trap does not apply

Look again: next filing.

J06 A bank's low P/E and high profit = safe Not applicable

not a bank

J08 A REIT's low net income = the dividend is unsafe Not applicable

not a REIT

What the statuses mean

Triggered: the filings show the pattern; read the normal explanations and the missing evidence before concluding anything. To review: one quarter or a weak signal; a reader's judgement, not a pattern. Not triggered: the pattern is absent on these figures. Insufficient data: the filings read so far do not hold what the rule needs; this is not a clean bill. Not applicable: the rule is not meant for this kind of company (a bank's working capital, a loss-making quarter's EPS growth). Out of date: the latest filing is more than fifteen months old.

Severity is what the pattern could mean for cash, value or solvency; confidence is how reliable the inputs and the reading are. The two are kept apart.

Every rule and the companies it triggers on → Alliant Energy: cash flow → Earnings quality score →

Each rule reads the company's own filings by a fixed formula and says what would explain the same figures innocently. A triggered rule is a question to verify, not a finding of manipulation, and not a view on the stock. Missing data is shown as missing, never as clear. Not investment advice.
