What these concentrations mean together

updated 2026-07-06

Five Star Bancorp's concentration profile is dominated by real estate. Real estate related loans represented approximately 86.07% of total loans before deferred fees at December 31, 2025, with commercial real estate loans alone — $3.3 billion — making up 81.08% of that total. Geographically, approximately 56.89% of real estate loans by dollar amount were secured by collateral in California, mostly Northern California. All three are structural, high-share exposures baked into the bank's core lending strategy rather than dependencies on individual counterparties, but their overlap is significant: a downturn concentrated in California commercial real estate would touch the large majority of the loan book simultaneously, which is the exposure most likely to move the verdict. Separately, the bank's 53 largest deposit relationships, each over $10.0 million, totaled $2.0 billion, or 47.82% of total deposits — a medium-share dependency exposure on the funding side. Together, the picture is a bank whose asset side is heavily and geographically concentrated in real estate, layered with a moderately concentrated deposit base. Disclosed in the most recent 10-K.

Concentration counts reflect items disclosed in each peer’s most recent 10-K; disclosed-size classification uses TrendMatrix’s internal 10-K extraction taxonomy.

Concentration disclosures are extracted verbatim from SEC 10-K filings; the disclosed-size classification and the synthesis above are engine-derived. Size reflects how large each exposure is against fixed share thresholds (HIGH >50%, MEDIUM 25–50%, LOW <25% or an explicit diversification statement), not a judgment of how dangerous it is, and is not a buy/sell rating, a price target, or a view on the stock.
