Ameren Illinois Company (AILIH): fair value, margin of safety and Wheel Score
Utilities · Regulated Electric · United States · High Growth
Is AILIH undervalued?
AILIH has a margin of safety of 48%: the stock closed at 61.78 on 16 Oct 2026 against a GLS average fair value of 118.96. 3 of the 7 valuation models that produced a number sit above the price. Our screens treat a discount this large as a strong starting point for a cash-secured put, not as a verdict - the fair value is a model output, and a wide gap can mean the models are missing something the market knows.
There is a wide gap between DCF (10.36) and Graham Growth (315.34). 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 AILIH under High Growth: revenue and earnings growing fast enough that the growth-based models carry the valuation.
Nine valuation models for AILIH
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.

| Lynch | 137.83 | +123% | EPS × the earnings growth rate (PEG of 1), growth capped at 25% |
| GLS Growth | 188.11 | +204% | 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 |

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 AILIH scores 5.3/10 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 6.60% (payout ratio 22%). 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 | 5.3 / 10 | ROE | 18.6% |
| Debt / equity | 0.00 | ROA | 7.1% |
| Free-cash-flow yield | -74.9% | Payout ratio | 22% |
| Institutions | 5 / 10 | Insiders · Congress | 5 · 5 / 10 |
Wheel Score 39: No options
No options are listed on Ameren Illinois Company in our nightly snapshot. The Wheel Score is therefore capped at 39 (it reads 39) 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 $1.6B, with a beta of 0.10 - 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.
| Part | Points | From | |
|---|---|---|---|
| Value | 25 / 25 | 48% margin of safety | |
| Health | 13 / 20 | Piotroski 6/9 | |
| Moat | 8 / 15 | moat 5.3/10 | |
| Premium | 0 / 20 | no option data | |
| Stability | 9 / 20 | 0k shares/day, $1.6B cap, beta 0.10 |
