James E. Beckwith, President and Chief Executive Officer, commented on the financial results:

“We delivered strong second quarter results driven by continued momentum in the markets we serve. Total loans increased by $157.2 million, or 20.2% when annualized, and total deposits increased by $193.9 million, or 26.2% when annualized, which we attribute to the growing demand for our differentiated customer experience and the strength of our team.

We are seeing a positive turn in net interest margin with a 25 basis point increase from 3.14% in the first quarter to 3.39% in the second quarter of 2024. We are pleased to have decreased short-term borrowings from $120.0 million to zero. We are also pleased that, in addition to a first quarter cash dividend in 2024, we declared a second quarter cash dividend of $0.20 per share, exemplifying our focus on shareholder value. To safeguard this value, we diligently monitor changing market conditions and are confident in the Bank’s resilience in any interest rate environment.

In the second quarter, our successful public offering resulted in the issuance of 3,967,500 additional shares of common stock with net proceeds of approximately $80.9 million, allowing us to execute on our organic growth strategy and maintain momentum in the San Francisco Bay Area. We now have 19 employees in the San Francisco Bay Area who have contributed $161.3 million in deposits since the expansion began in June 2023. We expect this momentum to continue and to benefit our shareholders, employees, clients, and community.

Summary Results

Three months ended June 30, 2024, as compared to three months ended March 31, 2024

The Company’s net income was $10.8 million for the three months ended June 30, 2024, as compared to $10.6 million for the three months ended March 31, 2024. Net interest income increased by $2.3 million, primarily due to an increase in interest income due to loan growth at higher yields bolstered by a decrease in interest expense due to lower average wholesale deposit balances, as compared to the three months ended March 31, 2024. The provision for credit losses increased by $1.1 million, with loan growth and increases in net charge-offs in the three months ended June 30, 2024 as the leading drivers. Non-interest income decreased by $0.3 million, primarily due to a reduction in gains from distributions received on equity investments in venture-backed funds during the three months ended June 30, 2024, as compared to the three months ended March 31, 2024. Non-interest expense increased by $0.8 million, primarily related to increases in: (i) commissions related primarily to higher loan production; (ii) travel, conferences, and professional membership fees; and (iii) sponsorships and donations, as compared to the three months ended March 31, 2024.

The Company’s net income was $10.8 million for the three months ended June 30, 2024, as compared to $12.7 million for the three months ended June 30, 2023. Net interest income increased by $1.5 million as increases in interest income due to loan growth at higher yields more than offset increases in interest expense due to larger average deposit balances at higher rates.

The increase in total assets from December 31, 2023 to June 30, 2024 was primarily due to a $184.6 million increase in total loans held for investment, partially offset by a $131.2 million decrease in cash and cash equivalents. The $184.6 million increase in total loans held for investment between December 31, 2023 and June 30, 2024 was a result of $539.9 million in loan originations and advances, partially offset by $150.0 million and $205.3 million in loan payoffs and paydowns, respectively. The $184.6 million increase in total loans held for investment included a purchase of loans within the consumer concentration of the loan portfolio, representing $73.3 million. The $131.2 million decrease in cash and cash equivalents primarily resulted from net cash outflows related to investing activities of $173.4 million, partially offset by net cash inflows related to financing and operating activities of $25.9 million and $16.3 million, respectively.

The decrease in total liabilities from December 31, 2023 to June 30, 2024 was primarily due to a decrease in other borrowings of $170.0 million, partially offset by an increase in interest-bearing deposits of $128.1 million. The increase in interest-bearing deposits was largely due to an increase in money market deposits of $281.8 million, partially offset by decreases in time deposits and interest-bearing demand deposits of $133.1 million and $20.5 million, respectively.

The increase in total shareholders’ equity from December 31, 2023 to June 30, 2024 was primarily a result of $80.9 million of additional common stock outstanding and net income recognized of $21.4 million, partially offset by $7.7 million in cash distributions paid during the period.

Net interest income during the three months ended June 30, 2024 increased $2.3 million and net interest margin increased 25 basis points compared to the three months ended March 31, 2024. Interest income increased $1.5 million compared to the prior quarter, primarily due to loan growth at higher yields. Average loan yields increased 12 basis points compared to the prior quarter, while average balances increased 3.75%. The increase in interest income compared to the prior quarter was bolstered by a $0.9 million decrease in interest expense, primarily due to lower average wholesale deposit balances. Average cost of wholesale deposits, individually, decreased 11 basis points compared to the prior quarter, while average balances decreased 38.93%. Average cost of total deposits, including wholesale deposits, decreased 6 basis points compared to the prior quarter, while average balances decreased 1.83%.

As compared to the three months ended June 30, 2023, net interest income increased $1.5 million and net interest margin decreased 6 basis points. The increase in net interest income is primarily attributable to loan growth at higher yields, partially offset by deposit growth at higher interest rates. Interest income increased by $6.2 million, as compared to the same quarter of the prior year. Average loan yields increased 33 basis points while average balances increased 9.73%, as compared to the same quarter of the prior year. The increase in interest income was partially offset by an additional $4.7 million in interest expense compared to the same quarter of the prior year.

Allowance for Credit Losses

At June 30, 2024, the Company’s allowance for credit losses was $35.4 million, as compared to $34.4 million at December 31, 2023. The $1.0 million increase in the allowance is due to a $3.0 million provision for credit losses recorded during the six months ended June 30, 2024, partially offset by net charge-offs of $2.0 million, mainly attributable to commercial and industrial loans, during the same period.

The Company’s ratio of nonperforming loans to loans held for investment remained at 0.06% between June 30, 2024 and December 31, 2023. Loans designated as watch increased from $39.6 million to $58.0 million between December 31, 2023 and June 30, 2024. Loans designated as substandard decreased from $2.0 million to $1.9 million between December 31, 2023 and June 30, 2024. There were no loans with doubtful risk grades at June 30, 2024 or December 31, 2023.

Salaries and employee benefits. The increase during the three months ended June 30, 2024 compared to the three months ended June 30, 2023 related primarily to: (i) a $0.9 million increase in salaries, benefits, and bonus expense for new employees hired since June 2023 to support expansion into the San Francisco Bay Area; (ii) a $0.3 million increase in commissions earned, largely due to commissions paid to the San Francisco Bay Area team, which did not occur during the three months ended June 30, 2023; and (iii) a $0.2 million decrease in loan origination costs due to lower loan production period-over-period.

Data processing and software.

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. 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. 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.

Investor Presentation Second Quarter 2024

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 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, 2023 and Quarterly Report on Form 10-Q for the three months ended March 31, 2024, 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, 2024 and for other quarterly periods are unaudited. Additionally, all figures presented as year-to-date, except 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. However, the Company acknowledges that its non-GAAP financial measures have a number of limitations. See the appendix to this presentation for a reconciliation of these non-GAAP measures to the most directly comparable GAAP financial measures. Second Quarter 2024 Investor Presentation | 2

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. 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 net income. 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.
