The business in brief
read the 10-K →What this business is and what moves its needle, from its own SEC filings.
- What moves the needle
- Net interest margin, loan losses, and book value. A lender is read on the quality of its balance sheet, not an earnings multiple, and the worst year of credit losses matters more than the best. On its own account, the filing leans hardest on customer concentration, set against the numbers in what the filing emphasizes, below.
- Is it a good business?
- Return on equity has run high across the record (median 17%, above 12% in 5 of 6 years). It runs at a 41% efficiency ratio, lean. A bank that earns above its cost of equity through the cycle compounds book value; whether this one did it by underwriting discipline or by reaching for risk is what the 10-K, and the worst years in the record, will tell you.
Every line is arithmetic on the company's filings, shown in full in the sections below.

Is it a good business?
- Return on equity 14%StrongNet income $62M ÷ equity $446MIndustry peers: median 10%
What this means
The bank's north star, what it earns on shareholders' capital. Cost of equity is roughly 10%, so a return durably above that builds value and below it destroys it. One year is noisy; the durability across a full credit cycle is what counts.
- SolidNet income ÷ (equity − goodwill $0 − intangibles $0)Industry peers: median 13%
What this means
The cleaner return, stripping out the goodwill paid for past acquisitions. This is the number a buyer of the whole bank actually earns on the hard capital.
- Efficiency ratio 41%Low cost ratio (<58%)Noninterest expense $65M ÷ (net interest income + fees)Industry peers: median 62%
What this means
The share of revenue eaten by running costs; lower is better, and below about 60% marks a genuinely efficient operation. A low ratio held for years is the operational side of a moat.
Is it sound?
- Capital (equity / assets) 9.4%AdequateEquity $446M ÷ assets $4.8B
What this means
A plain-English leverage read: how much of the balance sheet is the owners' own money. This is a rough proxy; the regulatory figure is the CET1 ratio, which is risk-weighted and reported in the filing. The point is the same, how much loss the bank can absorb before depositors are at risk.
- Deposit funding 88%Deposit-fundedDeposits $4.2B ÷ assets $4.8B
What this means
Low-cost, sticky deposits are a bank's real moat, the cheap raw material it lends out at a spread. A bank funded mostly by deposits earns more durably than one that rents its money in the wholesale market.
- Credit cost (provision / NII) 6%LowProvision for credit losses $10M ÷ net interest income $152M
What this means
What the bank set aside this year against loans going bad, as a share of its lending income. This swings hard with the cycle, low in good years and spiking in recessions, so read it across the record, not in one year. Disciplined underwriting shows up as low, stable provisions through a downturn.
Does AI threaten the moat?
Low contestabilityThe moat is physical, regulated or balance-sheet-funded, the kind AI cuts costs within but does not contest.
AI is unlikely to contest a moat that is physical, regulated or balance-sheet-funded; here it reads more as a cost tool than a threat.

Management, ownership & pay
read the proxy →From the proxy: how much of the business the people running it own, and how they are paid.
- Insider ownership21.8%
The stake all directors and executive officers hold together, per the 2026 proxy: skin in the game, the first thing Munger reads.
- Stock-based compensation$1M
The slice of the business handed to employees in shares this year, 1% of revenue, equal to 1% of operating profit. Buffett's oldest accounting fight: this is compensation, compensation is an expense, real whether or not the headline earnings admit it. One trap: the cash-flow statement adds SBC back, so the operating cash, and the owner earnings drawn from it, are flattered by exactly this amount; counted as the cost it is, what an owner keeps is lower.
Peers, Banks
The same industry, side by side on the bank lens. Each figure is a through-cycle median, so a peak or trough year can’t distort it; the group median at the foot is the line to read each against.

The price
What a price has to assume.
What the price implies
price / tangible bookA bank is worth a multiple of its tangible book value, and the multiple it deserves is set by the return it earns on that book. Type today’s price; we show what you would be paying against what Five Star Bancorp’s record justifies.
$
The assumptions
Tangible book / share, delivered9%/yr’20→’25
The justified multiple is (return on tangible equity − growth) ÷ (cost of equity − growth). A bank earning exactly its cost of equity is worth about one times tangible book; the premium above that prices each point of durable excess return. A higher cost of equity lowers the justified multiple for a bank.

Graham’s price gate—
Graham applied the same standards to financial enterprises (Intelligent Investor ch.14): the 15× multiple cap on averaged earnings, and P/E times price-to-book at most 22.5. The gate marks the bargain-hunter’s floor, not a verdict.

Tangible book $446M on 21M shares, a 17% normalized return on it. The dials set the multiple such a return would justify; your price sets the multiple you are paying. It assumes the bank keeps earning that return; a credit cycle, a rate shock or a bad acquisition changes it, which is what the record and the 10-K are for.
