Ameren Illinois Company (AILIN): fair value, margin of safety and Wheel Score
Ticker symbol AILIN · Utilities · Regulated Electric · United States · Blend Income
Is AILIN undervalued?
At 68.00 (close of 5 Nov 2026), AILIN trades 87% over the GLS average fair value of 36.30, with 0 of 7 models above the price. The stock earns none of the Wheel Score's Value points at this price. That is a statement about price against trailing fundamentals, not about the company's prospects - the Wall Street View and the Growth tab on the Quote page carry the forward numbers.
There is a wide gap between GLS Growth (9.41) and DDM (58.86). When the models are this far apart the "fair value" is really a range, and the margin of safety above should be read with that range in mind.
Ranked against every other company we cover, neither cheapness nor growth clearly wins for AILIN, so the nightly engine files it under Blend (value score 30, growth score 40, out of 100). It also carries the Income tag (Income = a dividend yield of 4% or more).
Nine valuation models for AILIN
Each model turns the latest filed numbers into a value per share; the GLS fair value is the simple average of the ones that produce a positive number. The last two rows are shown for reference and never enter the average. The Quote page lets you switch any model off and add your own margin of safety.
| Model | Value | vs price | What it measures |
|---|---|---|---|
| DCF | - | - | Present value of the projected free cash flows, discounted at the cost of capital; no value tonight |
| Graham Number | 43.40 | -36% | The most a defensive investor pays for the earnings and book value per share |
| Graham Growth | 51.86 | -24% | Graham's growth formula: EPS × (8.5 + 2 × growth), adjusted for bond yields |
| Lynch | 12.86 | -81% | EPS × the earnings growth rate (PEG of 1), growth capped at 25% |
| GLS Growth | 9.41 | -86% | EPS compounded ten years at the blended growth rate, discounted back at 15% a year |
| 10 Cap | 41.97 | -38% | Owner's earnings (operating cash flow less maintenance capex) capitalised at 10% |
| Payback Time | - | - | Eight years of compounded free cash flow: the price at which the business pays for itself; no value tonight |
| DDM | 58.86 | -13% | Dividend discount model: next year's dividend ÷ (10% − 3% growth); needs a dividend |
| EPV | 35.72 | -47% | Earnings power value: current EPS capitalised at 9% with no growth |
| Zombie (liquidation) | -27.02 | -140% | Current assets less all liabilities, per share: the balance-sheet floor. Not in the average |

Quality and financial health
Ameren Illinois Company scores 6 of 9 on the Piotroski F-score: a middling result that passes the "Piotroski 6 or more" Wheel Trade Filter. Some of the nine tests on profitability, leverage and efficiency are failed, so the accounts are worth a look before selling a put on the name. On durability AILIN scores 5.6/10 on the GLS Moat - a middle reading; the Moat Score tab on the Quote page's Financials view shows which of the four parts hold it back.
Returns on capital are moderate - ROIC 5.2%, ROE 9.4%, ROA 3.6% - with debt at 0.80 times equity and negative free cash flow.
The dividend yield is high at 6.67% (payout ratio 61%). A yield this size is often the market's way of pricing a risk to the payout, so the health score and cash flow matter more than usual. Revenue comes mainly from Electric 81%, Natural gas 19% (quarter Q2 FY2026).
Institutional ownership scores 5/10, insider activity 5/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 6 / 9 | ROIC | 5.2% |
|---|---|---|---|
| GLS Moat | 5.6 / 10 | ROE | 9.4% |
| Debt / equity | 0.80 | ROA | 3.6% |
| Free-cash-flow yield | -0.2% | Payout ratio | 61% |
| Institutions | 5 / 10 | Insiders · Congress | 5 · 5 / 10 |
Wheel Score 22: No options
No options are listed on Ameren Illinois Company in our nightly snapshot, so it fails the first Wheel Trade Filter (options that actually trade) (it reads 22, under 70) and is left out of every options scan; the fair value and health figures above are still useful for a plain stock position.
Volume runs at 0k shares a day on a market cap of $29.1B, with a beta of -0.25 - a low beta, so day-to-day moves are smaller than the market's; the Stability part of the Wheel Score rates that strong.
| Filter | Wheel Trade Filter | Result | Detail |

| 1 | Options that actually trade | Fails | no listed options |
| 2 | A real business, not a gamble | Passes | Profitable over the last twelve months - not a speculative stock, fund or note |
| 3 | Below fair value | Fails | trades 87% above our fair value |
| 4 | Financially healthy | Passes | Piotroski F-score 6 or more out of 9 (a company with no score on file passes) |
| 5 | Can repay its debt | Passes | Long-term debt repaid from 3 years of operating cash flow or less (6 for real estate and utilities; banks and insurers are not judged on it) |
| 6 | No serious red flags | Passes | Red Flags score 60 or more out of 100 (earnings, margins, debt, analysts, filings and price checked the same way for every stock) |
| 7 | A premium worth selling | Fails | no implied volatility |
| 8 | Big enough | Passes | Market cap $1 billion or more |
| 9 | Not a penny stock | Passes | Share price $5 or more |
