“Five Star Bank’s third quarter results include outstanding growth in loans and core deposits attributable to our successful organic growth strategy that continues to fuel momentum and drive demand for our differentiated customer experience. During the quarter, total loans held for investment increased by $129.2 million, or 3.44% (13.76% when annualized), and total deposits increased by $208.8 million, or 5.36% (21.45% when annualized). Wholesale deposits decreased by $150.2 million, or 22.87%, while non-wholesale deposits increased by $359.0 million, or 11.09% (44.34% when annualized), during the same period.

Cost of funds decreased two basis points to 2.51% during the third quarter, while net interest margin increased by three basis points to 3.56%, and our efficiency ratio decreased to 40.13% compared to 41.03% for the second quarter. This quarter, we are pleased to have declared another cash dividend to shareholders, which exemplifies our commitment to shareholder value.

In the third quarter, we opened our ninth full-service office in Walnut Creek, California, in response to the demand for our services in the San Francisco Bay Area. Total deposits from the San Francisco Bay Area were $548.9 million as of September 30, 2025. In addition to the new Walnut Creek office, we are pleased with the growth of our previously announced Food, Agribusiness, and Diversified Industries business, where clients benefit from our Global Trade Services and exceptional treasury management tools.

Five Star Bank’s success serves as a strong testimony to clients who value our team of committed professionals who provide authentic, relationship-based service. We will continue to ensure our technology stack, operating

efficiencies, conservative underwriting practices, exceptional credit quality, and prudent approach to portfolio management benefit our customers, employees, community, and shareholders. As we look to the fourth quarter of 2025, we 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 September 30, 2025, as compared to three months ended June 30, 2025

The Company’s net income was $16.3 million for the three months ended September 30, 2025, as compared to $14.5 million for the three months ended June 30, 2025. Net interest income increased by $2.8 million during the three months ended September 30, 2025, as compared to the three months ended June 30, 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 remained at $2.5 million for the three months ended June 30, 2025 and September 30, 2025. Non-interest income increased by $0.2 million, primarily due to an increase in swap referral fees during the three months ended September 30, 2025, as compared to the three months ended June 30, 2025. Non-interest expense increased by $0.9 million during the three months ended September 30, 2025, as compared to the three months ended June 30, 2025, primarily due to salaries and employee benefits due to increased headcount.

Net interest income during the three months ended September 30, 2025 increased $2.8 million, or 7.76%, to $39.3 million compared to $36.5 million during the three months ended June 30, 2025. Net interest margin totaled 3.56% for the three months ended September 30, 2025, an increase of three basis points compared to the prior quarter. The increase in net interest income is primarily attributable to an additional $4.3 million in interest income, mainly due to a $140.2 million, or 3.80%, increase in the average balance of loans and a five basis point improvement in the average yield on loans during the three months ended September 30, 2025 compared to the prior quarter. The increase in interest income was partially offset by an additional $1.4 million in interest expense, which was mainly driven by a $225.7 million, or 6.04%, increase in the average balance of deposits at an average rate of two basis points lower than the prior quarter. In addition, the average balance of non-interest bearing deposits increased by $59.5 million, or 6.22%, compared to the prior quarter.

As compared to the three months ended September 30, 2024, net interest income during the three months ended September 30, 2025 increased by $9.0 million, or 29.49%, to $39.3 million from $30.4 million. Net interest margin totaled 3.56% for the three months ended September 30, 2025, an increase of 19 basis points compared to the same quarter of the prior year. The increase in net interest income is primarily attributable to an additional $12.2 million in interest income, mainly due to a $477.8 million, or 14.25%, increase in the average balance of loans and a 16 basis point improvement in the average yield on loans during the three months ended September 30, 2025 compared to the same quarter of the prior year. The increase in interest income was partially offset by an additional $3.2 million in interest expense compared to the same quarter of the prior year. The increase in interest expense is mainly attributable to a $776.9 million, or 24.39%, increase in the average balance of deposits at an average rate of 19 basis points lower during the three months ended September 30, 2025 compared to the same quarter of the prior year. In addition, the average balance of non-interest-bearing deposits increased by $163.7 million, or 19.19%, compared to the same period of the prior year.

Allowance for Credit Losses

At September 30, 2025, the Company’s allowance for credit losses was $42.1 million, as compared to $37.8 million at December 31, 2024. The $4.3 million increase in the allowance is due to a $7.1 million provision for credit losses recorded during the nine months ended September 30, 2025, partially offset by net charge-offs of $2.8 million, primarily attributable to commercial and industrial loans, during the same period.

The Company’s ratio of nonperforming loans to loans held for investment remained at 0.05% at September 30, 2025 and December 31, 2024. Loans designated as watch decreased from $123.4 million to $92.7 million between December 31, 2024 and September 30, 2025. As a result, loans designated as substandard increased from $2.6 million to $18.6 million between December 31, 2024 and September 30, 2025, primarily attributable to the downgrade of one special purpose commercial real estate loan whose borrower was experiencing financial difficulty. There were no loans with doubtful risk grades at September 30, 2025 or December 31, 2024.

A summary of the allowance for credit losses by loan class is as follows:

September 30, 2025 December 31, 2024

This increase was partially offset by a $0.5 million increase in deferred loan origination costs due to a greater number of loan originations, net of purchased consumer loans, period-over-period.

Data processing and software. The increase was primarily due to: (i) increased usage of our digital banking platform; (ii) higher transaction volumes related to the increased number of loan and deposit accounts; and (iii) an increased number of licenses required for new users on our loan origination and documentation system.

Professional services. The increase was primarily due to a $0.1 million increase in fees paid for business development consulting services.

Advertising and promotional. The increase related primarily to additional expenses incurred to support the expansion of the Bank’s business development teams, including a $0.1 million increase in expenses related to

sponsored events and partnerships and a $0.1 million increase related to client and prospective client development expenses.

Other operating expenses. The increase was primarily due to: (i) a $0.1 million increase in administrative charges, including subscription services and bank charges; (ii) a $0.1 million increase in IntraFi Network fees resulting from an overall increase in balances carried in the network; and (iii) a $0.1 million increase in armored car and courier expenses.

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 December 31, 2025. These changes were not reflected in the income tax provision for the period ended September 30, 2025. The Company evaluated the impact on future periods and the legislation is not expected to have a significant impact on the Company's consolidated financial statements.

Three months ended September 30, 2025, as compared to three months ended June 30, 2025

Provision for income taxes increased to $5.9 million for the three months ended September 30, 2025 from $5.6 million for the three months ended June 30, 2025, which was primarily due to an increase in taxable income recognized during the three months ended September 30, 2025. The effective tax rates were 26.49% and 27.82% for the three months ended September 30, 2025 and June 30, 2025, respectively.

Three months ended September 30, 2025, as compared to three months ended September 30, 2024

Provision for income taxes increased by $1.6 million, or 36.98%, for the three months ended September 30, 2025 compared to the three months ended September 30, 2024. This increase was primarily driven by an increase in taxable income. The effective tax rates were 26.49% and 28.21% for the three months ended September 30, 2025 and September 30, 2024, respectively.

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 Reports on Form 10-Q for the three months ended March 31, 2025 and June 30, 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 September 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”).

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.

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.
