What matters now

• Solid but not exceptional quality (46/100) 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.

Analysis

CoastalSouth Bancshares, Inc (COSO) currently trades at $28.04, while our model-based Fair Value estimate is $22.86, implying the stock looks roughly 18.5% overvalued today. The Quality Score stands at 46/100 (below-average 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, CoastalSouth Bancshares, Inc generated revenue of $82.1M at a net margin of 31.9%. Revenue grew 18.4% year over year. It earns a return on equity of 11.3%. The balance sheet holds a net cash position of $11.5M. Fundamentals as of Jul 26, 2026

Our scenario range runs from $17.14 (bear case) to $28.57 (bull case); at $28.04, 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 near its 52-week high and 46% above its 52-week low, currently above its 200-day average. For context, the median of 10 Financial Services peers we cover trades at 42% fair-value upside, at -18%, COSO 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.

Widest divergence: Multiples ($26.89) versus Asset-Based ($14.45). Highest evidence: Residual Income (76).
