James E. Beckwith, President and Chief Executive Officer, commented:

“We proudly look back on 2025 as an outstanding year of achievement and are pleased to have experienced exceptional organic growth across all of the markets we serve, and consistent, strong financial performance. In 2025, Five Star Bank achieved year-over-year growth in total loans and total deposits. Total loans held for investment increased by $542.2 million, or 15%, and total deposits increased by $643.1 million, or 18%. Wholesale deposits decreased by $95.0 million, or 17%, while non-wholesale deposits increased by $738.1 million or 25%. Cost of funds decreased by 21 basis points from the third to the fourth quarter of 2025 and 17 basis points year-over-year. Our efficiency ratio decreased from 43.19% in 2024 to 41.03% in 2025, net income increased by 35%, or $15.9 million, in 2025, and earnings per share increased by $0.64 during 2025 to $2.90. We also experienced continued improvement in net interest margin expansion. We have provided a consistent shareholder dividend and, in recognition of our strong financial performance and commitment to returning value to our investors, we are pleased to announce an increase in the dividend this quarter. As we look ahead to 2026, we believe that managing expenses and executing on conservative underwriting practices will continue to be foundational to our success.

In 2025, we expanded our San Francisco Bay Area market presence with the opening of our Walnut Creek office. We also announced the expansion of our Agribusiness vertical. In 2026, we plan to continue to focus on building all of the verticals and markets we serve by providing high tech and high touch service to clients who appreciate our differentiated client experience. These efforts have helped us maintain a position of distinction and respect with our clients, employees, and community partners. In 2025, we were among Piper Sandler’s 2025 Sm-All Stars, and earned an IDC Superior rating and a Bauer Financial rating of 5 stars (out of five). We were also awarded the prestigious 2024 Raymond James Community Bankers Cup, were among S&P Global Market Intelligence’s 2024 Top 3 Best-Performing Community banks in the nation (with assets between $3 billion and $10 billion), and were ranked fourth on the 2025 Bank Director Magazine (RankingBanking) Best U.S. Banks with assets less than $5 billion.

In 2025, our senior leadership was recognized by the San Francisco Business Times with a placement on the Newsmaker 100 List and with a 40 Under 40 recognition. We were also recognized by the Sacramento Business Journal with a Champion for DE&I award, a Power 100 List placement, a Women Who Mean Business honor, and a C-Suite award. Senior leadership also received a Sacramento State Alumni Association Distinguished Alumni Award, a Sacramento Cultural Hub Media Foundation Exceptional Women of Color honor, a Commercial Real Estate Women Nancy Hotchkiss Woman of Impact award, a Sacramento Hispanic Chamber of Commerce Champion Latina Estrella award, and a Sacramento Metropolitan Chamber of Commerce Sacramentan of the Year award.

We are proud of Five Star Bank’s achievements in 2025 and are focused on continued success in the future.”

Summary Results

Three months ended December 31, 2025, as compared to three months ended September 30, 2025

The Company’s net income was $17.6 million for the three months ended December 31, 2025, as compared to $16.3 million for the three months ended September 30, 2025. Net interest income increased by $2.7 million, primarily due to an increase in interest income driven by a larger average balance of interest-earning assets, augmented by a decrease in interest expense due to a lower average cost of deposits, as compared to the prior quarter. The provision for credit losses increased by $0.3 million, reflecting increases in loan growth and an overall increase in loss rates related to deterioration in the unemployment rate forecast in the three months ended December 31, 2025, as compared to the three months ended September 30, 2025. Non-interest income decreased by $0.6 million, primarily due to an overall decline in earnings related to equity investments in venture-backed funds during the three months ended December 31, 2025, as compared to the prior quarter. Non-interest expense increased by $1.1 million, primarily due to increased salaries and employee benefits due to increased headcount.

Three months ended December 31, 2025, as compared to three months ended December 31, 2024

The Company’s net income was $17.6 million for the three months ended December 31, 2025, as compared to $13.3 million for the three months ended December 31, 2024. Net interest income increased by $8.6 million, 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 due to deposit growth. The provision for credit losses increased by $1.5 million, mainly due to increases in loan growth and an overall increase in loss rates related to the annual current expected credit losses (“CECL”) model refresh during the three months ended December 31, 2025, as compared to the three months ended December 31, 2024. Non-interest income decreased by $0.3 million, primarily due to an overall decline in earnings related to equity investments in venture-backed funds during the three months ended December 31, 2025, as compared to the same quarter of the prior year. Non-interest expense increased by $3.2 million, primarily due to increased salaries and employee benefits due to increased headcount.

Year ended December 31, 2025, as compared to year ended December 31, 2024

The Company’s net income was $61.6 million for the year ended December 31, 2025, as compared to $45.7 million for the year ended December 31, 2024. Net interest income increased by $32.2 million, 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 due to deposit growth. The provision for credit losses increased by $2.8 million, or 39.57%, mainly due to increases in loan growth and an overall increase in loss rates related to the annual CECL model refresh during the three months ended December 31, 2025, as compared to the year ended December 31, 2024. Non-interest income increased by $0.1 million, primarily due to growth across multiple sources of revenue.

This growth was substantially negated by a reduction in gain on sale of loans, attributable to the strategic reduction in origination of loans held for sale during the year ended December 31, 2025, as compared to the prior year. Non-interest expense increased by $10.5 million, primarily due to increased salaries and employee benefits due to increased headcount.

All values are in US Dollars.

The increase in total assets from December 31, 2024 to December 31, 2025 was primarily due to a $542.2 million increase in total loans held for investment and a $154.5 million increase in cash and cash equivalents. The $542.2 million increase in total loans held for investment between December 31, 2024 and December 31, 2025 was the result of $1.4 billion in loan originations and advances, partially offset by $338.5 million and $502.6 million in loan payoffs and paydowns, respectively. The $542.2 million increase in total loans held for investment included $92.1 million in purchased loans within the consumer concentration of the loan portfolio. The $154.5 million increase in cash and cash equivalents primarily resulted from the net increase in cash inflows from growth in total deposits of $643.1 million and cash outflows from growth in total loans held for investment of $542.2 million.

The increase in total liabilities from December 31, 2024 to December 31, 2025 was primarily attributable to an increase in deposits of $643.1 million. The $643.1 million increase in deposits was largely due to increases in money market, non-interest-bearing demand, interest-bearing transaction, and savings deposits of $553.3 million, $161.9 million, $29.0 million, and $14.5 million, respectively. These increases were partially offset by decreases in time deposits of $115.5 million, largely driven by a $95.0 million decrease in wholesale deposits.

The increase in total shareholders’ equity from December 31, 2024 to December 31, 2025 was primarily a result of $61.6 million recognized as net income, partially offset by $17.1 million in cash dividends paid during the period.

Net interest income during the three months ended December 31, 2025 increased $2.7 million, or 6.91%, to $42.1 million, as compared to $39.3 million during the three months ended September 30, 2025. Net interest margin totaled 3.66% for the three months ended December 31, 2025, an increase of ten basis points compared to the prior quarter. The increase in net interest income is primarily attributable to an additional $1.8 million in loan interest income due to a $140.3 million, or 3.66%, increase in the average balance of loans, partially offset by a five basis point decrease in the average yield on loans during the three months ended December 31, 2025, as compared to the prior quarter. The increase in interest income was augmented by a $1.1 million decrease in interest expense due to a 21 basis point decrease in the average cost of deposits during the three months ended December 31, 2025 compared to the prior quarter, driven primarily by two rate cuts occurring during the three months ended December 31, 2025. The average balance of deposits increased by $163.6 million, or 4.13%, during the three months ended December 31, 2025, but the substantial decrease in the cost associated with deposits led to a net reduction in total interest expense.

As compared to the three months ended December 31, 2024, net interest income increased $8.6 million, or 25.61%, to $42.1 million from $33.5 million. Net interest margin totaled 3.66% for the three months ended December 31, 2025, an increase of 30 basis points compared to the same quarter of the prior year. The increase in net interest income is primarily attributable to an additional $8.2 million in loan interest income due to a $474.1 million, or 13.55%, increase in the average balance of loans and an eight basis point improvement in the average yield on loans during the three months ended December 31, 2025, as compared to the same quarter of the prior year. The increase in interest income was partially offset by a $0.1 million increase in deposit interest expense due to a $563.9 million, or 15.83%, increase in the average balance of deposits during the three months ended December 31, 2025. The average cost of deposits during the three months ended December 31, 2025 was 2.23%, a decrease of 35 basis points compared to the same quarter of the prior year, which helped to moderate the increase in interest expense related to deposits.

Net interest margin totaled 3.55% for the year ended December 31, 2025, an increase of 23 basis points compared to the prior year. The increase in net interest income is primarily attributable to an additional $35.9 million in loan interest income due to a $483.3 million, or 14.72% increase in the average balance of loans and a 19 basis point improvement in the average yield on loans as compared to the prior year. The increase in interest income was partially offset by an additional $10.0 million in deposit interest expense due to a $627.4 million, or 19.45% increase in the average balance of deposits during the year. The average cost of deposits was 2.40% for the year ended December 31, 2025, a decrease of 16 basis points compared to the prior year which helped to moderate the increase in interest expense related to deposits.

Allowance for Credit Losses

At December 31, 2025, the Company’s allowance for credit losses was $44.4 million, as compared to $37.8 million at December 31, 2024. The $6.6 million increase in the allowance is due to a $9.8 million provision for credit losses recorded during the twelve months ended December 31, 2025, partially offset by net charge-offs of $3.1 million, mainly 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 0.08% at December 31, 2025. The increase resulted mainly from the occurrence of two separate faith-based real estate loans entering nonperforming status. Loans designated as watch decreased from $123.4 million to $101.9 million between December 31, 2024 and December 31, 2025. Consequently, loans designated as substandard increased from $2.6 million to $22.3 million between December 31, 2024 and December 31, 2025, primarily attributable to the downgrade of one borrower experiencing financial difficulty with a special purpose commercial real estate loan and a commercial line of credit. There were no loans with doubtful risk grades at December 31, 2025 or December 31, 2024.

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

December 31, 2025 December 31, 2024

The increase was primarily due to an additional $0.2 million in donations and $0.2 million related to sponsored events and partnerships, combined with $0.4 million of additional expenses incurred to support the expansion of the Bank’s business development teams, specifically related to client and prospective client development expenses.

Loan-related expenses. The increase was due to an increase of $0.1 million in inspection fees and an increase of $0.1 million in loan-related legal expenses, both due to loan growth between December 31, 2024 and December 31, 2025.

Other operating expenses. The increase was due to: (i) a $0.4 million increase in employee-related expenses, such as travel, conferences, training, and professional association memberships; (ii) a $0.2 million increase in armored car and courier expenses; (iii) a $0.2 million increase in administrative charges, including subscription services and bank charges; (iv) a $0.1 million increase in IntraFi Network fees resulting from an overall increase in balances carried in the network; (v) a $0.1 million increase in office expenses, such as check printing and supplies; and (vi) a $0.1 million increase in regulatory assessment fees.

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 December 31, 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 December 31, 2025, as compared to the three months ended September 30, 2025

Provision for income taxes for the quarter ended December 31, 2025 decreased by $0.5 million, or 8.91%, to $5.4 million, as compared to $5.9 million for the quarter ended September 30, 2025, which was primarily due to a $0.9 million benefit recorded during the quarter ended December 31, 2025 related to the purchase of transferable tax credits. This was partially offset by: (i) an increase in pre-tax income recognized during the three months ended December 31, 2025; and (ii) a $0.3 million adjustment recorded during the three months ended December 31, 2025 related primarily to a true-up of amortization expense related to low income housing tax credits, which did not occur during the three months ended September 30, 2025. The effective tax rate was 23.32% and 26.49% for the three months ended December 31, 2025 and September 30, 2025, respectively.

Three months ended December 31, 2025, as compared to the three months ended December 31, 2024

Provision for income taxes decreased by $0.7 million, or 11.32%, to $5.4 million for the three months ended December 31, 2025, as compared to $6.1 million for the three months ended December 31, 2024. This decrease is primarily due to a $0.9 million benefit recorded during the quarter ended December 31, 2025 related to the purchase of transferable tax credits. This was partially offset by a $0.3 million adjustment recorded during the three months ended December 31, 2025 related primarily to a true-up of amortization expense related to low income housing tax credits, which did not occur during the three months ended December 31, 2024. The effective tax rate was 23.32% and 31.24% for the three months ended December 31, 2025 and December 31, 2024, respectively.

Year ended December 31, 2025, as compared to the year ended December 31, 2024

Provision for income taxes increased by $3.1 million, or 16.15%, to $22.1 million for the year ended December 31, 2025, as compared to $19.1 million for the year ended December 31, 2024. This increase is primarily due to a 29.37% increase in pre-tax income recognized during the year ended December 31, 2025. This was partially offset by: (i) a $0.9 million benefit recorded during the quarter ended December 31, 2025 related to the purchase of transferable tax credits; and (ii) a net $0.2 million reduction to the provision recorded during the quarter 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 rate was 26.42% and 29.43% for the years ended December 31, 2025 and December 31, 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 Reports on Form 10-Q for the quarters ended March 31, 2025, June 30, 2025, and September 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 December 31, 2025 and for other quarterly periods are unaudited. Additionally, numbers contained in this presentation for the full fiscal year ended December 31, 2025 are unaudited. 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) Fourth Quarter 2025 Investor Presentation | 32 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.
