- For a financial, book-value and earnings-based methods matter more than a cash-flow DCF, which fits banks and insurers poorly.

Analysis
International Bancshares Corporation (IBOC) currently trades at $71.54, while our model-based Fair Value estimate is $76.53, implying the stock looks roughly 6.5% fairly valued today. The Quality Score stands at 60/100 (solid quality), in the Financial Services sector. Bull case: the Multiples group reads highest at a median of $73.21 per share, and 2 of the 6 models we run sit above the $71.54 price. Bear case: the Dividend Discount group reads lowest at $18.06, and 4 of the 6 models stay below the price. Evidence for this calculation is high.
Over the trailing twelve months, International Bancshares Corporation generated revenue of $838M at a net margin of 49.9%. Revenue grew 5.4% year over year. It earns a return on equity of 13.5%. Net debt stands at $168M. Fundamentals as of Sep 3, 2026
Our scenario range runs from $57.40 (bear case) to $95.66 (bull case); at $71.54, 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 4% below its 52-week high and 19% above its 52-week low, currently above its 200-day average. For context, the median of 10 Financial Services peers we cover trades at −10% fair-value upside, at 7%, IBOC screens cheaper than that median.
Fair Value models
This estimate rests on fiscal year 2025 figures, and about 8 months have passed since. In that time the company retained roughly $3.58 per share, which is 4.7 % of the fair value. The fair value deliberately does not add this in: the models value reported figures, not a projection.
Each model estimates fair value its own way; the Fair Value above is the evidence-weighted, family-balanced 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. Every input is real reported data, nothing guessed.
All 6 models by family
Widest divergence: Multiples ($73.21) versus Dividend Discount ($18.06). Highest evidence: Residual Income (71).

Quality Score breakdown
Of which business quality 53 · Market factors (momentum, volatility) 57
Non-valuation factor families (profitability, growth, cashflow, financial strength, momentum …), each academically grounded. Valuation itself sits in the Fair Value and is deliberately excluded here to avoid double-counting.
All values are scores from 0 to 100 (100 = best against fixed, research-based bands), not percentages. The three market factors (momentum, 52-week proximity, low volatility) are displayed but carry zero weight in the headline number: market sentiment is not a business property.
