Ameren Illinois Company (AILLI): fair value, margin of safety and Wheel Score
Utilities · Regulated Electric · United States · High Yield Income
Is AILLI undervalued?
AILLI closed at 79.51 on 16 Oct 2026, more than 30% above the GLS average fair value of 58.15. Only 1 of the 6 models that produced a value sit above the price. By our models the shares are priced well beyond what the filed earnings, cash flow and book value support; the Sunday Scan drops names like this at the "below fair value" rule.
There is a wide gap between GLS Growth (17.98) and Graham Growth (99.08). 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.
The nightly engine files AILLI under High Yield Income: a dividend yield above 4%.
Nine valuation models for AILLI
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.

| Graham Growth | 99.08 | +25% | Graham's growth formula: EPS × (8.5 + 2 × growth), adjusted for bond yields |
| Lynch | 24.57 | -69% | EPS × the earnings growth rate (PEG of 1), growth capped at 25% |
| GLS Growth | 17.98 | -77% | EPS compounded ten years at the blended growth rate, discounted back at 15% a year |
| 10 Cap | - | - | Owner's earnings (operating cash flow less maintenance capex) capitalised at 10%; no value tonight |
| Payback Time | - | - | Eight years of compounded free cash flow: the price at which the business pays for itself; no value tonight |

Quality and financial health
Ameren Illinois Company scores 6 of 9 on the Piotroski F-score: a middling result that passes the Sunday Scan's "6 or more" rule. 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 AILLI scores 5.7/10 on the GLS Moat - a middle reading; the Scorecard on the Quote page's Financials tab shows which ten-year lines are steady and which are not.
Returns on capital are high - ROIC 18.5%, ROE 18.6%, ROA 7.1% - with debt at 0.00 times equity and negative free cash flow.
The dividend yield is high at 6.49% (payout ratio 20%). 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 | 18.5% |
|---|---|---|---|
| GLS Moat | 5.7 / 10 | ROE | 18.6% |
| Debt / equity | 0.00 | ROA | 7.1% |
| Free-cash-flow yield | -58.2% | Payout ratio | 20% |
| Institutions | 5 / 10 | Insiders · Congress | 5 · 5 / 10 |
Wheel Score 31: No options
No options are listed on Ameren Illinois Company in our nightly snapshot. The Wheel Score is therefore capped at 39 (it reads 31) and the stock is left out of every options screen; 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 $2.0B, with a beta of 0.02 - a low beta, so day-to-day moves are smaller than the market's; the Stability part of the Wheel Score gives that 9 of 20.

|---|---|---|---|
| Value | 0 / 25 | -37% margin of safety | |
| Health | 13 / 20 | Piotroski 6/9 | |
