Isabella Bank Corporation (ISBA): fair value, margin of safety and Wheel Score

Is ISBA undervalued?

ISBA closed at 41.89 on 5 Nov 2026, 27% below the GLS average fair value of 57.08 from 9 models (5 of them above the price). That is a moderate margin of safety: the stock passes the "below fair value" Wheel Trade Filter, with room for a bigger discount on the Value part.

There is a wide gap between DDM (16.48) and Graham Growth (130.88). 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 ISBA, so the nightly engine files it under Blend (value score 57, growth score 51, out of 100).

Nine valuation models for ISBA

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.

Quality and financial health

Isabella Bank Corporation 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 ISBA scores 5.7/10 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 5.1%, ROE 8.2%, ROA 0.9% - with debt at 0.62 times equity and a free-cash-flow yield of 8.8%.

The dividend yield is 2.67% at a payout ratio of 38%; for a wheel trader holding assigned shares the dividend adds to the covered-call premium, and the ex-dividend date is worth knowing before a call is sold. Revenue comes mainly from Debit Card 37%, Fiduciary and Trust 31%, Service Charges And Deposit Account Fees 11% (quarter Q3 FY2026).

Institutional ownership scores 3/10, insider activity 10/10 and Congressional trading 5/10 on the GLS smart-money scales.

Wheel Score 32: No options

No options are listed on Isabella Bank Corporation in our nightly snapshot, so it fails the first Wheel Trade Filter (options that actually trade) (it reads 32, 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 66k shares a day on a market cap of $321M, with a beta of 0.03 - a low beta, so day-to-day moves are smaller than the market's; the Stability part of the Wheel Score rates that fair.

The Wheel Score ranks ~7,400 US stocks for selling cash-secured puts and covered calls: a stock must pass all 9 Wheel Trade Filters to score 70, and the score then ranks the ones that pass; the Sunday Scan is the top 10. It is updated nightly and is not a recommendation. How the Wheel Score works · the walkthrough lesson shows how it fits into a trade, start to finish.
