&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<sup>(1)</sup> See the section entitled "Non-GAAP Reconciliation (Unaudited)" for a reconciliation of this non-GAAP financial measure.

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

*"The strength of Five Star Bank's first quarter 2026 financial results is emblematic of seized market opportunities fueled by the continued demand for our differentiated customer experience. In the first quarter of 2026, we successfully executed on our strategic plan and declared a cash dividend of $0.25 per share to shareholders (an increase of $0.05 per share from dividends declared in each quarter of 2025). Earnings per share increased to $0.87 per share, up $0.04 from the fourth quarter of 2025 and $0.25 from the first quarter of 2025. Net income increased to $18.6 million, up from $17.6 million for the fourth quarter of 2025, while total cost of funds decreased 10 basis points to 2.20% during the first quarter of 2026, and net interest margin increased by four basis points to 3.70%. We are pleased that over the first quarter, total loans held for investment increased by $138.5 million, or 3% (14% when annualized) while total deposits increased by $268.3 million, or 6% (26% when annualized). As we execute on the expansion of industry verticals and our presence in new geographies to meet customer demand, we expect the ongoing acceleration of our growth to benefit our customers, employees, and shareholders."*

**<u>Summary Results</u>**

*Three months ended March 31, 2026, as compared to three months ended December 31, 2025*

The Company's net income was $18.6 million for the three months ended March 31, 2026, as compared to $17.6 million for the three months ended December 31, 2025. Net interest income increased by $1.4 million during the three months ended March 31, 2026, as compared to the three months ended December 31, 2025, primarily due to an increase in interest income driven by loan growth, augmented by a decrease in interest expense driven by a decline in the average cost of deposits. The provision for credit losses decreased by $0.1 million during the three months ended March 31, 2026, as compared to the three months ended December 31, 2025, primarily due to a slight improvement in estimated loss rates. Non-interest income increased by $0.2 million, primarily due to an increase in fees from swap referrals and a special FHLB stock dividend, partially offset by an overall decline in earnings related to investments in venture-backed funds during the three months ended March 31, 2026, as compared to the three months ended December 31, 2025. Non-interest expense decreased by $0.3 million during the three months ended March 31, 2026, as compared to the three months ended December 31, 2025, primarily due to the release of a loss contingency on a U.S. Small Business Administration ("SBA") loan that did not occur during the three months ended December 31, 2025, partially offset by increased salaries and employee benefits due to increased headcount during the three months ended March 31, 2026.

*Three months ended March 31, 2026, as compared to three months ended March 31, 2025*

The Company's net income was $18.6 million for the three months ended March 31, 2026, as compared to $13.1 million for the three months ended March 31, 2025. Net interest income increased by $9.5 million during the three months ended March 31, 2026, 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 $0.8 million, reflecting increases in loan growth and an overall increase in loss rates in the three months ended March 31, 2026 compared to the three months ended March 31, 2025. Non-interest income increased by $0.3 million, primarily due to an increase in fees from swap referrals and a special FHLB stock dividend, partially offset by an overall decline in earnings related to investments in venture-backed funds during the three months ended March 31, 2026, as compared to the three months ended March 31, 2025. Non-interest expense increased by $2.3 million during the three months ended March 31, 2026, as compared to the three months ended March 31, 2025, primarily due to increased salaries and employee benefits due to increased headcount.

The increase in total assets from December 31, 2025 to March 31, 2026 was primarily comprised of a $138.5 million increase in total loans held for investment and a $137.5 million increase in cash and cash equivalents. The $138.5 million increase in total loans held for investment between December 31, 2025 and March 31, 2026 was a result of $389.0 million in loan originations and advances, partially offset by $67.9 million and $182.6 million in loan payoffs and paydowns, respectively. The $137.5 million increase in cash and cash equivalents primarily resulted from the net increase in cash inflows from growth in total deposits of $268.3 million and cash outflows from growth in total loans held for investment of $138.5 million.

The increase in total liabilities from December 31, 2025 to March 31, 2026 was primarily due to an increase in deposits of $268.3 million. The increase in deposits was largely due to increases in money market and non-interest-bearing deposits of $212.6 million and $148.2 million, respectively, partially offset by a $100.3 million decrease in time deposits, mainly attributed to an $81.9 million decline in wholesale deposits.

The increase in total shareholders' equity from December 31, 2025 to March 31, 2026 was primarily a result of $18.6 million recognized as net income, partially offset by $5.3 million in cash dividends paid during the period and a $1.0 million increase in accumulated other comprehensive loss.

Net interest income during the three months ended March 31, 2026 increased by $1.4 million, or 3.31%, to $43.5 million, as compared to $42.1 million during the three months ended December 31, 2025. Net interest margin totaled 3.70% for the three months ended March 31, 2026, an increase of four basis points compared to the prior quarter. The increase in net interest income is primarily attributable to an additional $0.9 million in interest income, mainly due to a $178.3 million, or 4.49%, increase in the average balance of loans during the three months ended March 31, 2026 compared to the prior quarter. The increase in interest income was augmented by a $0.5 million decrease in interest expense due to a 10 basis point decrease in the average cost of deposits during the three months ended March 31, 2026 compared to the prior quarter. The average balance of deposits increased by $195.0 million, or 4.73%, during the three months ended March 31, 2026, but the decrease in the cost associated with deposits led to a net reduction in total interest expense. In addition, the average balance of non-interest bearing deposits increased by $54.8 million, or 5.14%, compared to the prior quarter.

As compared to the three months ended March 31, 2025, net interest income during the three months ended March 31, 2026 increased by $9.5 million, or 27.90%, to $43.5 million from $34.0 million. Net interest margin totaled 3.70% for the three months ended March 31, 2026, an increase of 25 basis points compared to the same quarter of the prior year. The increase in net interest income is primarily attributable to an additional $10.3 million in interest income, mainly due to a $582.5 million, or 16.32%, increase in the average balance of loans and a five basis point improvement in the average yield on loans during the three months ended March 31, 2026, as compared to the same quarter of the prior year. The increase in interest income was partially offset by a $0.8 million increase in interest expense due to a $734.4 million, or 20.48%, increase in the average balance of deposits during the three months ended March 31, 2026. The average cost of deposits during the three months ended March 31, 2026 was 2.13%, 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. In addition, the average balance of non-interest-bearing deposits increased by $211.1 million, or 23.17%, compared to the same period of the prior year.

At March 31, 2026, the Company's allowance for credit losses was $46.4 million, as compared to $44.4 million at December 31, 2025. The $2.0 million increase in the allowance is due to a $2.6 million provision for credit losses recorded during the three months ended March 31, 2026, partially offset by net charge-offs of $0.6 million, primarily attributable to commercial and industrial loans, during the same period.

The Company's ratio of nonperforming loans to loans held for investment decreased to 0.07% at March 31, 2026 from 0.08% at December 31, 2025.

| Total non-interest income | $1643 | $1359 | $284 | 20.90% |

---

---

*Salaries and employee benefits.* The increase related primarily to: (i) a $2.3 million increase in salaries, benefits, and bonus expense, mainly related to a 17.48% increase in headcount between March 31, 2025 and March 31, 2026; and (ii) a $0.5 million increase in commissions paid. This increase was partially offset by a $0.6 million increase in deferred loan origination costs due to higher loan originations period-over-period.

*Occupancy and equipment.* The increase was primarily due to expenses for the Walnut Creek branch office and Newport Beach non-depository office during the three months ended March 31, 2026, which did not exist for the three months ended March 31, 2025.

*Advertising and promotional.* The increase related primarily to additional expenses incurred to support the expansion of the Bank's business development teams, including $0.1 million related to business development expenses and $0.1 million related to donation, sponsorship, and advertising expenses.

*Other operating expenses.* The decrease related primarily to the release of a $1.0 million loss contingency on an SBA loan during the three months ended March 31, 2026. No such release occurred during the three months ended March 31, 2025. This was partially offset by individually immaterial increases in expenses related to operations, including administration, courier service, and travel.

**<u>Provision for Income Taxes</u>**

*Three months ended March 31, 2026, as compared to three months ended December 31, 2025*

Provision for income taxes increased by $1.0 million, or 19.48%, for the three months ended March 31, 2026, as compared to the three months ended December 31, 2025, which was primarily due to: (i) an increase in taxable income recognized; and (ii) a $0.7 million net reduction in transferable tax credits recognized during the three months ended March 31, 2026. The effective tax rates were 25.61% and 23.32% for the three months ended March 31, 2026 and December 31, 2025, respectively.

*Three months ended March 31, 2026, as compared to three months ended March 31, 2025*

Provision for income taxes increased by $1.1 million, or 21.40%, for the three months ended March 31, 2026, as compared to the three months ended March 31, 2025. This increase was primarily driven by an increase in taxable income, partially offset by a $0.2 million benefit recorded during the three months ended March 31, 2026 related to the purchase of transferable tax credits that did not occur during the three months ended March 31, 2025. The effective tax rates were 25.61% and 28.71% for the three months ended March 31, 2026 and March 31, 2025, respectively.

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 press release. 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, 2025 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.

**<u>Non-GAAP Reconciliation (Unaudited)</u>**

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, 2025, 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 March 31, 2026 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"). 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.

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. 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. First Quarter 2026 Investor Presentation \| 32
