Profitable, growing coastal community bank at a fair ~1.24x book and 12.4x earnings — own it, but modest ROE and hurricane/CRE concentration cap the upside.

Net income $24.9M · FY2025

The read

Middling fundamentals offset by an attractive price (~99% below fair value) — worth a look on the value angle.

Ignore the headline 'revenue $1.99M,' 'P/S 162x,' and 'net margin 1254%' — those are XBRL artifacts. The tag RevenueFromContractWithCustomerExcludingAssessedTax captures only noninterest/fee income, not the net interest income that drives a bank. The real business is a $2.31B-asset commercial bank (Hilton Head/Savannah/Atlanta footprint) that earned $24.9M net income, up a healthy 13.6% YoY, on assets that grew 9.9%. That works out to ROA of roughly 1.08% — a solid, above-1% result for a community bank — and ROE of 9.6%. Book value is ~$21.67/share, so at $26.83 the stock trades at about 1.24x book and 12.4x diluted EPS: a fair-to-slightly-full price, not a bargain, but not stretched either. Balance sheet looks clean: 7.89x liabilities/equity is normal bank leverage, cash grew 17%, retained earnings jumped 59%, and operating cash flow of $63.1M dwarfs the trivial $1.83M capex.

The key nuance dampening the bull case: net income rose 13.6% but diluted EPS rose only 3.3%, and equity ballooned 32.9%. That gap is the July 2025 NYSE IPO — the company issued shares, so per-share earnings were diluted and the fresh capital pushed ROE down to single digits. A bank earning ~9.6% ROE, arguably at or below its cost of equity, deserves only a slight premium to book, which is roughly where 1.24x sits. So the stock is priced about right for what it currently earns; the upside case depends on management deploying that new IPO capital into profitable growth to lift ROE back toward double digits.
