Five Star Bancorp grows loans to US$4.5b

• Five Star Bancorp’s total loans reached US$4,521.9 million in Q2 2026, up from US$4,215.7 million in Q1 2026 and US$3,760.3 million in Q2 2025, giving the bank more interest earning assets to work with.
• Consensus narrative suggests expansion into Bay Area and Walnut Creek, along with new business development hires, is helping create these loan opportunities. The data also shows trailing twelve month net income of US$72.0 million and revenue of US$167.6 million that need to support that growth in a concentrated Northern California footprint.
  • Supporters of the bullish view point to analysts’ expectations for revenue to grow around 18.4% per year, which sits above the 12.8% forecast for the wider US market, as evidence that this larger loan book can keep contributing to revenue.
  • At the same time, critics of the concentrated growth strategy may focus on the reliance on regional economic conditions, given that total loans have climbed by roughly US$761.7 million over the last five reported quarters while exposure is still tied closely to Northern California.

Margins solid, but efficiency and credit quality in focus

• The net interest margin printed at 3.63% in Q2 2026 compared with 3.53% in Q2 2025 and 3.56% in Q3 2025. The cost to income ratio sat at 40.91% in Q2 2026 versus 41.03% in Q2 2025 and 38.57% in Q1 2026, and non performing loans were US$13.4 million in Q2 2026 versus US$2.8 million in Q1 2026 and US$2.3 million in Q2 2025.
• Bears argue that heavy exposure to commercial real estate and a concentrated deposit base could pressure margins and credit quality, and the jump in non performing loans to US$13.4 million gives them a concrete data point to watch.
  • The consensus narrative highlights commercial real estate, including office and multifamily, as a key risk, and the rise in non performing loans from levels between roughly US$1.8 million and US$3.1 million across earlier quarters to US$13.4 million in Q2 2026 aligns with that concern.
  • On the cost side, expansion into new markets and verticals is expected to lift non interest expenses, and the move in the cost to income ratio from 38.57% in Q1 2026 to 40.91% in Q2 2026 fits with bears’ focus on how quickly new spending translates into earnings.

Valuation sits between peers and DCF fair value

• Five Star Bancorp trades on a trailing P/E of 14.1x compared with a peer average of 15.6x and a US Banks industry average of 12.1x. The current share price of US$46.81 sits below both the analyst price target of US$49.00 and a DCF fair value of US$85.45.
• Consensus narrative frames the stock as broadly fairly priced against analyst expectations, yet the DCF fair value and earnings profile invite a more optimistic angle that investors need to reconcile with the growth and risk numbers.
  • Earnings grew 38.8% over the last year and the trailing net profit margin is 43% versus 39.3% in the prior year, which strongly supports those who see value in paying a modest premium to the industry P/E for Five Star Bancorp.
  • However, earnings are forecast to grow 11.8% per year compared with a 17.8% forecast for the broader US market, so investors weighing the P/E of 14.1x and the DCF fair value of US$85.45 against the current price of US$46.81 need to balance stronger recent profitability with slower forecast earnings growth than the wider market.
