James E. Beckwith, President and Chief Executive Officer, commented:
“We are very pleased to report an exceptional quarter where the continuation of our organic growth strategy fueled new account openings and resulted in growth in loans and deposits. Total loans held for investment increased by $136.2 million, or 3.76% (15.04% when annualized), and total deposits increased by $158.3 million, or 4.24% (16.94% when annualized). Net interest margin increased by eight basis points to 3.53%, while our efficiency ratio decreased to 41.03% compared to 42.58% for the first quarter of 2025. Short-term borrowings remained at zero as of June 30, 2025 and December 31, 2024. This quarter, we declared another dividend to shareholders, which exemplifies our commitment to shareholder value.
This success serves as a strong testimony to our people, technology, operating efficiencies, conservative underwriting practices, exceptional credit quality, and prudent approach to portfolio management, which we believe will continue to benefit our clients, employees, community, and shareholders. It is also attributable to our relationship-based banking approach, where clients receive high-tech and high-touch concierge business banking services.
We look forward to bringing these services to the Walnut Creek market, where we expect to open an office in the third quarter of 2025. Since our expansion in the San Francisco Bay Area began in June 2023, the team has grown to 34 employees with $456.9 million in deposits as of June 30, 2025. We also look forward to the continued growth of business verticals, including Food, Agribusiness, and Diversified Industries where we believe clients will benefit from our global trade services and exceptional treasury management tools.
As we look to the second half of 2025, we are humbled and proud of our team’s accomplishments. We also thank our employees for their outstanding commitment to ensuring Five Star Bank remains a safe, trusted, and steadfast banking partner.”

Summary Results
Three months ended June 30, 2025, as compared to three months ended March 31, 2025
The Company’s net income was $14.5 million for the three months ended June 30, 2025, as compared to $13.1 million for the three months ended March 31, 2025. Net interest income increased by $2.5 million during the three months ended June 30, 2025, as compared to the three months ended March 31, 2025, primarily due to an increase in interest income driven by loan growth and an improvement in the average yield on loans, partially offset by an increase in interest expense driven by deposit growth. The provision for credit losses increased by $0.6 million, with loan growth and increases in net charge-offs during the three months ended June 30, 2025 as the leading drivers. Non-interest income increased by $0.5 million, primarily due to an overall improvement in the estimated earnings related to investments in venture-backed funds during the three months ended June 30, 2025, as compared to the three months ended March 31, 2025. Non-interest expense increased by $0.7 million during the three months ended June 30, 2025, as compared to the three months ended March 31, 2025, primarily related to increases in business travel, conferences, training, and advertising and promotional expenses associated with expansion of the Bank’s business development teams, partially offset by an increase in deferred loan origination costs.

The provision for credit losses increased by $0.5 million, with increases in net charge-offs during the three months ended June 30, 2025 as the leading driver. Non-interest income increased by $0.2 million, primarily due to an overall improvement in the estimated earnings related to investments in venture-backed funds, partially offset by a decrease in the volume of loans sold during the three months ended June 30, 2025, as compared to the three months ended June 30, 2024. Non-interest expense increased by $2.2 million during the three months ended June 30, 2025, as compared to the three months ended June 30, 2024, with an increase in salaries and employee benefits related to increased headcount as the leading driver.

The $225.3 million increase in total loans held for investment included $43.9 million in purchases of loans within the consumer concentration of the loan portfolio. The $131.5 million increase in cash and cash equivalents primarily resulted from net cash inflows related to financing and operating activities of $328.1 million and $28.1 million, respectively, partially offset by net cash outflows related to investing activities of $224.7 million.

The increase in total shareholders’ equity from December 31, 2024 to June 30, 2025 was primarily a result of net income recognized of $27.6 million and a $0.4 million increase in accumulated other comprehensive income, partially offset by $8.5 million in cash dividends paid during the period.

Net interest income during the three months ended June 30, 2025 increased $2.5 million, or 7.47%, to $36.5 million compared to $34.0 million during the three months ended March 31, 2025. Net interest margin totaled 3.53% for the three months ended June 30, 2025, an increase of eight basis points compared to the prior quarter. The increase in net interest income is primarily attributable to an additional $3.5 million in interest income, mainly due to a $123.6 million, or 3.46%, increase in the average balance of loans and a seven basis point improvement in the average yield on loans during the three months ended June 30, 2025 compared to the prior quarter. The increase in interest income was partially offset by an additional $1.0 million in interest expense, which was mainly driven by a $150.2 million, or 4.19%, increase in the average balance of deposits at an average rate of two basis points lower than the prior quarter.
As compared to the three months ended June 30, 2024, net interest income increased $7.4 million, or 25.52%, to $36.5 million from $29.1 million. Net interest margin totaled 3.53% for the three months ended June 30, 2025, an increase of 14 basis points compared to the same quarter of the prior year. The increase in net interest income is primarily attributable to an additional $11.6 million in interest income, mainly due to a $493.7 million, or 15.44%, increase in the average balance of loans and a 26 basis point improvement in the average yield on loans during the three months ended June 30, 2025 compared to the same quarter of the prior year. The increase in interest income was partially offset by an additional $4.2 million in interest expense compared to the same quarter of the prior year. The increase in interest expense is mainly attributable to a $686.1 million, or 22.50%, increase in the average balance of deposits at an average rate of one basis point lower during the three months ended June 30, 2025 compared to the same quarter of the prior year.

At June 30, 2025, the Company’s allowance for credit losses was $40.2 million, as compared to $37.8 million at December 31, 2024. The $2.4 million increase in the allowance is due to a $4.6 million provision for credit losses recorded during the six months ended June 30, 2025, partially offset by net charge-offs of $2.2 million, primarily attributable to commercial and industrial loans, during the same period.
The Company’s ratio of nonperforming loans to loans held for investment increased from 0.05% at December 31, 2024 to 0.06% at June 30, 2025.

Provision for Income Taxes
On July 4, 2025, the President signed H.R. 1, the “One Big Beautiful Bill Act,” into law. The legislation includes several changes to federal tax law that generally allow for more favorable deductibility of certain business expenses beginning in 2025, including the restoration of immediate expensing of domestic R&D expenditures, reinstatement of 100% bonus depreciation, and more favorable rules for determining the limitation on business interest expense. The Act also made certain changes to the deductibility of the cost of meals and charitable contributions that are effective for tax years beginning after Dec. 31, 2025. These changes were not reflected in the income tax provision for the period ended June 30, 2025, as enactment occurred after the balance sheet date. The Company is currently evaluating the impact on future periods.
Three months ended June 30, 2025, as compared to three months ended March 31, 2025
Provision for income taxes increased to $5.6 million for the three months ended June 30, 2025 from $5.3 million for the three months ended March 31, 2025, which was primarily due to an increase in taxable income recognized during the three months ended June 30, 2025. This increase was partially offset by a net $0.2 million reduction to the provision recorded during the three months ended June 30, 2025. This adjustment related to a tax law change for the state of California effective as of June 30, 2025, which requires a transition from a three-factor apportionment formula to a single-sales-factor formula for determining state income tax. As such, the Company recorded a net benefit of approximately $0.9 million relating to the current year provision, which was partially offset by a $0.7 million expense relating to the remeasuring of the deferred tax assets and liabilities as of June 30, 2025. The
effective tax rates were 27.82% and 28.71% for the three months ended June 30, 2025 and March 31, 2025, respectively.
Three months ended June 30, 2025, as compared to three months ended June 30, 2024
Provision for income taxes increased by $1.2 million, or 27.94%, for the three months ended June 30, 2025 compared to the three months ended June 30, 2024. This increase was primarily driven by an increase in taxable income. This increase was partially offset by a net $0.2 million reduction to the provision recorded during the three months ended June 30, 2025. This adjustment related to a tax law change for the state of California effective as of June 30, 2025, which requires a transition from a three-factor apportionment formula to a single-sales-factor formula for determining state income tax. As such, the Company recorded a net benefit of approximately $0.9 million relating to the current year provision, which was partially offset by a $0.7 million expense relating to the remeasuring of the deferred tax assets and liabilities as of June 30, 2025. The effective tax rates were 27.82% and 28.84% for the three months ended June 30, 2025 and June 30, 2024, respectively.

Non-GAAP Reconciliation (Unaudited)
The Company uses financial information in its analysis of the Company’s performance that is not in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The Company believes that these non-GAAP financial measures provide useful information to management and investors that is supplementary to the Company’s financial condition, results of operations, and cash flows computed in accordance with GAAP. However, the Company acknowledges that its non-GAAP financial measures have a number of limitations. As such, investors should not view these disclosures as a substitute for results determined in accordance with GAAP. Additionally, these non-GAAP measures are not necessarily comparable to non-GAAP financial measures that other banking companies use. Other banking companies may use names similar to those the Company uses for the non-GAAP financial measures the Company discloses, but may calculate them differently. Investors should understand how the Company and other companies each calculate their non-GAAP financial measures when making comparisons.
Tangible shareholders’ equity to tangible assets is defined as total equity less goodwill and other intangible assets, divided by total assets less goodwill and other intangible assets. The most directly comparable GAAP financial measure is total shareholders’ equity to total assets. Management believes that tangible shareholders’ equity to tangible assets is a useful financial measure because it enables management, investors, and others to assess the Company’s financial health based on tangible capital. We had no goodwill or other intangible assets at the end of any period indicated. As a result, tangible shareholders’ equity to tangible assets is the same as total shareholders’ equity to total assets at the end of each of the periods indicated.
Tangible book value per share is defined as total shareholders’ equity less goodwill and other intangible assets, divided by the outstanding number of common shares at the end of the period. The most directly comparable GAAP financial measure is book value per share. Management believes that tangible book value per share is a useful financial measure because it enables management, investors, and others to assess the Company’s value and use of equity. We had no goodwill or other intangible assets at the end of any period indicated. As a result, tangible book value per share is the same as book value per share at the end of each of the periods indicated.
Pre-tax, pre-provision income is defined as pre-tax income plus provision for credit losses. The most directly comparable GAAP financial measure is pre-tax income. Management believes that pre-tax, pre-provision income is a useful financial measure because it enables management, investors, and others to assess the Company’s ability to generate operating profit and capital.

Safe Harbor Statement and Disclaimer Forward-Looking Statements In this presentation, “we,” “our,” “us,” “Five Star,” or “the Company” refers to Five Star Bancorp, a California corporation, and our consolidated subsidiaries, including Five Star Bank, a California state- chartered bank, unless the context indicates that we refer only to the parent company, Five Star Bancorp. This presentation contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements represent plans, estimates, objectives, goals, guidelines, expectations, intentions, projections, and statements of the Company’s beliefs concerning future events, business plans, objectives, expected operating results, and the assumptions upon which those statements are based. Forward-looking statements include without limitation, any statement that may predict, forecast, indicate, or imply future results, performance, or achievements, and are typically identified with words such as “may,” “could,” “should,” “will,” “would,” “believe,” “anticipate,” “estimate,” “expect,” “aim,” “intend,” “plan,” or words or phases of similar meaning. The Company cautions that the forward-looking statements are based largely on the Company’s expectations and are subject to a number of known and unknown risks and uncertainties that are subject to change based on factors which are, in many instances, beyond the Company’s control. Such forward-looking statements are based on various assumptions (some of which may be beyond the Company’s control) and are subject to risks and uncertainties, which change over time, and other factors which could cause actual results to differ materially from those currently anticipated. New risks and uncertainties may emerge from time to time, and it is not possible for the Company to predict their occurrence or how they will affect the Company. If one or more of the factors affecting the Company’s forward-looking information and statements proves incorrect, then the Company’s actual results, performance, or achievements could differ materially from those expressed in, or implied by, forward-looking information and statements contained in this presentation. Therefore, the Company cautions you not to place undue reliance on the Company’s forward-looking information and statements. Important factors that could cause actual results to differ materially from those in the forward-looking statements are set forth in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 and Quarterly Report on Form 10-Q for the three months ended March 31, 2025, in each case under the section entitled “Risk Factors,” and other documents filed by the Company with the Securities and Exchange Commission from time to time. The Company disclaims any duty to revise or update the forward-looking statements, whether written or oral, to reflect actual results or changes in the factors affecting the forward-looking statements, except as specifically required by law. Industry Information This presentation includes statistical and other industry and market data that we obtained from government reports and other third-party sources. Our internal data, estimates, and forecasts are based on information obtained from government reports, trade, and business organizations and other contacts in the markets in which we operate and our management’s understanding of industry conditions. Although we believe that this information (including the industry publications and third-party research, surveys, and studies) is accurate and reliable, we have not independently verified such information. In addition, estimates, forecasts, and assumptions are necessarily subject to a high degree of uncertainty and risk due to a variety of factors. Finally, forward-looking information obtained from these sources is subject to the same qualifications and the additional uncertainties regarding the other forward-looking statements in this presentation. Unaudited Financial Data Numbers contained in this presentation for the quarter ended June 30, 2025 and for other quarterly periods are unaudited. Additionally, all figures presented as year-to-date and for periods that represent a full fiscal year ended December 31, represent unaudited results. As a result, subsequent information may cause a change in certain accounting estimates and other financial information, including the Company’s allowance for credit losses, fair values, and income taxes. Non-GAAP Financial Measures The Company uses financial information in its analysis of the Company’s performance that is not in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The Company believes that these non-GAAP financial measures provide useful information to management and investors that is supplementary to the Company’s financial condition, results of operations, and cash flows computed in accordance with GAAP.

Appendix: Non-GAAP Reconciliation (Unaudited) The Company uses financial information in its analysis of the Company's performance that is not in conformity with GAAP. The Company believes that these non- GAAP financial measures provide useful information to management and investors that is supplementary to the Company's financial condition, results of operations, and cash flows computed in accordance with GAAP. However, the Company acknowledges that its non-GAAP financial measures have a number of limitations. As such, investors should not view these disclosures as a substitute for results determined in accordance with GAAP. Additionally, these non-GAAP measures are not necessarily comparable to non-GAAP financial measures that other banking companies use. Other banking companies may use names similar to those the Company uses for the non-GAAP financial measures the Company discloses but may calculate them differently. Investors should understand how the Company and other companies each calculate their non-GAAP financial measures when making comparisons. Average loan yield, excluding PPP loans, is defined as the daily average loan yield, excluding PPP loans, and includes both performing and nonperforming loans. The most directly comparable GAAP financial measure is average loan yield. Management believes that average loan yield, excluding PPP loans, is a useful financial measure because it enables management, investors, and others to assess the Company's ability to manage yield on core loans. We had no PPP loans nor interest and fee income on PPP loans for the periods shown in this presentation other than the years ended December 31, 2020, 2021, and 2022. As a result, average loan yield, excluding PPP loans, is the same as daily average loan yield for all periods presented other than the years ended December 31, 2020, 2021, and 2022. Reconciliations for such periods are provided below. Total assets, excluding PPP loans, is defined as total assets less PPP loans. The most directly comparable GAAP financial measure is total assets. Management believes that total assets, excluding PPP loans, is a useful financial measure because it enables management, investors, and others to assess the Company's ability to manage core assets. We had no PPP loans as of the period ends shown in this presentation other than as of December 31, 2020 and 2021. As a result, total assets, excluding PPP loans, is the same as total assets for all periods presented, other than as of December 31, 2020 and 2021. Reconciliations for such periods are provided below. Pre-tax, pre-provision income is defined as pre-tax income plus provision for credit losses. The most directly comparable GAAP financial measure is pre-tax income. Management believes that pre-tax, pre-provision income is a useful financial measure because it enables management, investors, and others to assess the Company's ability to generate operating profit and capital. Tangible book value per share is defined as total shareholders’ equity less goodwill and other intangible assets, divided by the outstanding number of common shares at the end of the period. The most directly comparable GAAP financial measure is book value per share. Management believes that tangible book value per share is a useful financial measure because it enables management, investors, and others to assess the Company's value and use of equity.
