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.”

Summary Results
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.

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.

Allowance for Credit Losses
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. Loans designated as watch increased from $101.9 million to $143.5 million between December 31, 2025 and March 31, 2026. Loans designated as substandard increased from $22.3 million to $23.4 million between December 31, 2025 and March 31, 2026. There were no loans with doubtful risk grades at March 31, 2026 or December 31, 2025.

This increase was partially offset by a $0.4 million decrease in commissions paid.

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.
Provision for Income Taxes
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.

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.
