From 4 valuation models · updated 16 days ago
Share price +1.4% over the past month.
A solid business, but screening 16% overvalued on our models.
What matters now
- Solid but not exceptional quality (62/100) and above fair value, neither a clear bargain nor a standout compounder.
- For a financial, book-value and earnings-based methods matter more than a cash-flow DCF, which fits banks and insurers poorly.

How to read this chart
60‑month range $12.21 – $56.22 · fair‑value band $25.15 – $41.92 · the $39.77 price screens above the $33.53 fair value. Green steps = our fair value per fiscal year (point-in-time, no hindsight). Dashed = 300-day average. As of Jul 26, 2026.
Analysis
Isabella Bank Corporation (ISBA) currently trades at $39.77, while our model-based Fair Value estimate is $33.53, implying the stock looks roughly 15.7% overvalued today. The Quality Score stands at 62/100 (solid quality), in the Financial Services sector. Bear case: priced above our estimate, the market already discounts strong expectations. Bull case: above-average quality can justify a premium, the entry price still matters most (evidence: high).
Over the trailing twelve months, Isabella Bank Corporation generated revenue of $81.6M at a net margin of 24.5%. Revenue grew 13.7% year over year. It earns a return on equity of 8.9%. Net debt stands at $116M. Fundamentals as of Jul 26, 2026
Our scenario range runs from $25.15 (bear case) to $41.92 (bull case); at $39.77, the current price sits within that range. Bear and bull are the same models run on conservative and optimistic assumptions (margins, growth, valuation multiples), so a plausible valuation range, not a price target. The share trades about 32% below its 52-week high and 42% above its 52-week low, currently below its 200-day average. For context, the median of 10 Financial Services peers we cover trades at 42% fair-value upside, at -16%, ISBA screens richer than that median.
Fair Value models
Each model estimates fair value its own way; the Fair Value above is the evidence-weighted blend. Evidence (0–100) measures how completely this model’s inputs are available: well-fed models carry more weight in the blend. The spread across models is intentional, each one stresses a different value driver; dividend models, for instance, come out structurally low when payout is small.
All 4 models by family
Widest divergence: Multiples ($33.53) versus Asset-Based ($21.15). Highest evidence: Residual Income (76).
