Third Quarter Operating Results

Net Income

Net income for the third quarter of 2026 was $14.0 million, or $0.43 per diluted share, compared with $14.3 million, or $0.44 per diluted share in the second quarter of 2026. Pre-tax, pre-provision income (non-GAAP¹) for the third quarter was $21.6 million, an increase of $1.1 million, or 5.27%, from the prior quarter. The net income and diluted earnings per share decreases were largely driven by higher provision for credit losses and noninterest expense, partially offset by higher net interest income and noninterest income.

Net Interest Income and Net Interest Margin

Net interest income for the third quarter of 2026 was $44.1 million, compared with $43.4 million in the prior quarter. The increase in net interest income was primarily due to a $1.4 million increase in total interest and dividend income, partially offset by a $581 thousand increase in total interest expense in the third quarter of 2026, as compared with the prior quarter. The increase in net interest income was also impacted by one additional day in the current quarter compared with the prior quarter.

During the third quarter of 2026, total interest income increased by $1.4 million. The increase was primarily driven by a $1.2 million increase in total loan interest income, which included a decrease of $18 thousand in accretion from the net purchase accounting discounts on acquired loans and $366 thousand reversals of interest income on loans placed on nonaccrual. In addition, total debt securities income increased $113 thousand, and interest income from deposits in other financial institutions increased $497 thousand. These increases were partially offset by a decrease of $353 thousand in dividend income from restricted stock investments and other bank stock and a decrease of $123 thousand in interest income from Fed funds sold/resale agreements. The increase in interest income was mainly due to the growth in average interest-earning assets, partially offset by a decline of 9 basis points in the yield on average total interest-earning assets as a result of changes in asset mix, and reversals of interest associated with nonaccrual loans. Average interest-earning assets were positively impacted by increases in average total loans of $68.1 million, average total debt securities of $1.6 million, and average deposits in other financial institutions of $51.0 million, partially offset by a decrease in average Fed funds sold/resale agreements of $12.2 million. The increase in interest expense for the third quarter of 2026 was primarily due to a $682 thousand increase in interest expense on average total interest-bearing deposits, the result of higher average total interest-bearing deposits of $95.5 million, partially offset by a $101 thousand decrease in borrowing expense from the redemption of the $35 million subordinated debt on September 1, 2026.

Net interest margin for the third quarter of 2026 was 4.61%, compared with 4.71% in the prior quarter. The decrease in the net interest margin of 10 basis points was primarily driven by a decline of 9 basis points in the total interest-earning assets yield, coupled with an increase of 1 basis point in the cost of funds. The yield on total average interest-earning assets in the third quarter of 2026 was 5.88%, compared with 5.97% in the prior quarter. The yield on average total loans in the third quarter of 2026 was 6.29%, a decrease of 5 basis points from 6.34% in the prior quarter. The yield on average total loans in the third quarter of 2026 included the impact of the nonaccrual interest reversals noted above, which decreased the overall loan yield by 5 basis points. This compares to an increase of 7 basis points in overall total loan yield in the prior quarter from cash interest collection on the payoff of two nonaccrual loans, net of interest reversals on loans placed on nonaccrual. Accretion income from the net purchase accounting discounts on acquired loans was $3.3 million, increasing the yield on average total loans by 42 basis points; the net amortization expense from the purchase accounting discounts on acquired subordinated debt and acquired time deposits premium increased interest expense by $389 thousand, the combination of which increased the net interest margin by 31 basis points in the third quarter of 2026. In the prior quarter, accretion income from the net purchase accounting discounts on acquired loans was $3.3 million, increasing the yield on average total loans by 44 basis points; the net amortization expense from the purchase accounting discounts on acquired subordinated debt and acquired time deposits premium increased the interest expense by $389 thousand, the combination of which increased the net interest margin by 32 basis points.

Cost of funds for the third quarter of 2026 was 1.39%, an increase of 1 basis point from 1.38% in the prior quarter. The increase was a result of an increase of 1 basis point in the cost of average total interest-bearing deposits, driven primarily by changes in the Company’s deposit mix and increased competition for deposits driving market deposit rates upward in the third quarter of 2026. The amortization expense of $389 thousand from the purchase accounting discounts on acquired subordinated debt and acquired time deposits premium contributed 4 basis points to the cost of funds. Average noninterest-bearing demand deposits increased $17.4 million to $1.24 billion and represented 36.0% of total average deposits for the third quarter of 2026, compared with $1.22 billion and 36.7%, respectively, in the prior quarter; average interest-bearing deposits increased $95.5 million to $2.21 billion during the third quarter of 2026. The total cost of deposits in the third quarter of 2026 was 1.33%, compared with 1.31% in the prior quarter.

Average total borrowings decreased $10.9 million to $23.5 million in the third quarter of 2026, primarily due to the redemption of the $35.0 million subordinated debt in September 2026. The average cost of total borrowings was 10.04% for the third quarter of 2026, up from 8.10% in the prior quarter. The increase in cost of total borrowings during the quarter was primarily the result of amortization of the remaining fair value adjustment associated with the redemption of the subordinated debt.

Provision for Credit Losses

The Company recorded a provision for credit losses of $3.2 million for the third quarter of 2026, compared with $714 thousand in the prior quarter. The provision for credit losses in the third quarter of 2026 was comprised of a $3.2 million provision for credit losses on loans held for investment, partially offset by a $16 thousand reversal of provision for credit losses for unfunded loan commitments. Total unfunded loan commitments decreased by $34.5 million to $862.4 million at September 30, 2026, compared to $896.9 million in unfunded loan commitments at June 30, 2026.

The provision for credit losses for loans held for investment in the third quarter of 2026 was $3.2 million, an increase of $2.2 million from $1.1 million in the prior quarter. The increase reflected $4.6 million in net charge-offs, primarily related to the full charge-off of two commercial and industrial loans, updates to the reasonable and supportable economic forecasts for California, revised scenario weighting assumptions, continued loan growth, and changes in portfolio composition, partially offset by a decline in accruing substandard and special mention loan balances and refinements to the qualitative factors. The Company’s management continues to monitor macroeconomic variables including changes in interest rates, uncertainty in the current economic environment, and elevated geopolitical risks related to ongoing conflicts in the Middle East. Management believes it has appropriately provisioned for the current environment.

Noninterest Income

Total noninterest income was $1.9 million in the third quarter of 2026, an increase of $351 thousand compared with $1.6 million in the second quarter of 2026. Other charges and fees increased $260 thousand in the third quarter due primarily to a reduction in loss from equity investments of $30 thousand in the third quarter of 2026 compared to a loss from equity investments of $251 thousand in the prior quarter.

Noninterest Expense

Total noninterest expense for the third quarter of 2026 was $24.4 million, an increase of $57 thousand, compared with $24.3 million in the prior quarter. Salaries and employee benefits decreased $157 thousand during the third quarter of 2026 to $15.4 million primarily due to lower overall payroll tax and incentive accruals, partially offset by a decrease in loan origination costs deferred based on decreased loan origination activity. Legal, audit and professional expense increased $229 thousand during the third quarter of 2026. Other real estate owned expenses decreased $197 thousand in the third quarter of 2026 primarily from overall lower holding costs.

Efficiency ratio (non-GAAP¹) for the third quarter of 2026 was 53.00%, compared with 54.22% in the prior quarter.

Income Tax

In the third quarter of 2026, the Company’s income tax expense was $4.4 million, compared with $5.5 million for the second quarter of 2026. The effective rate was 23.9% for the third quarter of 2026 and 27.9% for the second quarter of 2026. The decrease in income tax expense and the effective tax rate for the third quarter of 2026 was primarily driven by a $725 thousand tax benefit recognized from tax credits purchased in the third quarter of 2026.

Balance Sheet

Assets

Total assets at September 30, 2026 were $4.11 billion, an increase of $80.4 million or 2.0% from June 30, 2026. The increase in total assets from the prior quarter was primarily related to an increase of $53.3 million in loans, including loans held for sale, a $10.1 million increase in available-for-sale debt securities, a $4.4 million increase in deferred taxes and a $9.1 million increase in accrued interest and other assets, primarily driven by the tax credits purchased in the third quarter.

Loans

Total loans held for investment (“LHFI”) were $3.15 billion at September 30, 2026, an increase of $53.8 million, compared with June 30, 2026. During the third quarter of 2026, new loans totaled $241.5 million, consisting of $159.9 million of new loan fundings, $10.8 million of Community Reinvestment Act (“CRA”) eligible small business loan participation purchases to support the Company’s CRA strategy and small business lending objectives, and $70.8 million of short-term participation purchases in fully collateralized mortgage loans. Separately, advances on existing loans totaled $81.2 million. These increases were partially offset by $124.7 million loan payoffs, paydowns and others changes totaling $76.7 million, $4.6 million of full charge-offs of two commercial and industrial loans, and $62.8 million of short-term participation purchases in fully collateralized mortgage loans that were sold to approved third-party mortgage brokers or investors. Total loans secured by real estate increased by $44.1 million, of which construction and land development loans increased $19.9 million, other commercial real estate loans increased $19.1 million; multifamily loans increased $8.9 million, and commercial and industrial loans increased $10.8 million, including $34.5 million of aforementioned participation purchases in mortgage loans through approved warehouse facilities and $10.8 million of aforementioned participation purchases in CRA-eligible small business loans; partially offset by 1-4 family residential and consumer loans decreasing by $3.8 million and $1.1 million, respectively.

The Company had $15.4 million in loans held for sale at September 30, 2026, consisting entirely of consumer solar loans, compared with $15.8 million at June 30, 2026.

Deposits

Total deposits at September 30, 2026 were $3.48 billion, an increase of $117.4 million from June 30, 2026. The increase was primarily due to increases in interest-bearing non-maturity deposits of $115.5 million and noninterest-bearing demand deposits of $4.9 million, partially offset by a decrease in non-brokered time deposits of $3.1 million. Noninterest-bearing demand deposits at September 30, 2026, were $1.26 billion, or 36.3% of total deposits, compared with $1.26 billion, or 37.4% of total deposits at June 30, 2026. At September 30, 2026, total interest-bearing deposits were $2.21 billion, compared with $2.10 billion at June 30, 2026. At September 30, 2026, the Company did not have any brokered time deposits. The Company offers the Insured Cash Sweep product and Certificate of Deposit Account Registry Service, each of which provides reciprocal deposit placement services to fully qualified large customer deposits for FDIC insurance among other participating banks. Total reciprocal deposits were $740.3 million, or 21.3% of total deposits at September 30, 2026, compared with $705.2 million, or 21.0% of total deposits at June 30, 2026.

Federal Home Loan Bank ("FHLB") and Liquidity

At September 30, 2026 and June 30, 2026, the Company had no FHLB or Federal Reserve Discount Window borrowings.

At September 30, 2026, the Company had available borrowing capacity from an FHLB secured line of credit of approximately $752.5 million and available borrowing capacity from the Federal Reserve Discount Window of approximately $317.5 million. The Company also had available borrowing capacity from four unsecured credit lines from correspondent banks of approximately $90.5 million at September 30, 2026, with no outstanding borrowings. Total available borrowing capacity was $1.16 billion at September 30, 2026. Additionally, the Company had unpledged liquid securities at fair value of approximately $215.7 million and cash and cash equivalents of $266.7 million at September 30, 2026.

During the third quarter of 2026, the Company redeemed all $35.0 million of its 3.50% fixed-to-floating rate subordinated debt due September 1, 2031, at par value. Starting in September 2026, the interest rate on that subordinated debt was scheduled to transition from a fixed rate to a quarterly variable rate equal to the then current 90-day SOFR plus 2.86%, through the contractual maturity date of September 1, 2031.

Asset Quality

Total non-performing assets were $17.9 million, or 0.44% of total assets at September 30, 2026, an increase of $407 thousand, or 2.3%, from $17.5 million, or 0.44% of total assets, at June 30, 2026. Total non-performing loans were $9.3 million, or 0.30% of total loans held for investment at September 30, 2026, compared with $8.9 million, or 0.29% of total loans held for investment at June 30, 2026.

Total nonperforming loans increased $407 thousand, or 4.6%, during the third quarter of 2026 primarily driven by the downgrades of a commercial and industrial loan and a commercial real estate loan. These loans are classified as individually evaluated, collateral-dependent loans and no allowance for loan loss was recorded at September 30, 2026, as full repayments are anticipated.

Special mention loans decreased by $8.4 million during the third quarter of 2026 to $40.3 million at September 30, 2026. The decrease in the special mention loans was due mostly to $5.9 million of loans downgraded to substandard, coupled with $5.8 million in upgrades to pass rating, $1.2 million in net paydowns, and $356 thousand in payoffs, partially offset by $4.9 million of loans downgraded from pass rating.

Substandard loans decreased by $5.5 million during the third quarter of 2026 to $58.7 million at September 30, 2026. The decrease in the substandard loans was due primarily to full charge-offs of two commercial and industrial loans totaling $4.6 million from one relationship, coupled with $3.3 million in upgrades to pass rating, $2.0 million in payoffs and $1.5 million in net paydowns, partially offset by $5.9 million of loans downgraded from special mention. The aforementioned charge-offs are related to a long-term, online advertisement client. Challenges related to unauthorized third-party use of the client’s proprietary software caused a rapid, material decline in revenue, ultimately leading the company to cease operations with limited recovery opportunities.

The Company had no LHFI that were over 90 days past due and still accruing interest at September 30, 2026 and June 30, 2026, respectively.

Loan delinquencies (30-89 days past due, excluding nonaccrual loans) totaled $80 thousand at September 30, 2026, compared with $4.9 million in such loan delinquencies at June 30, 2026. The decrease was primarily due to $2.4 million of loans brought to current, $2.0 million in payoffs, and $372 thousand of a commercial and industrial loan downgraded to nonaccrual, partially offset by $6.0 thousand of loans that became delinquent during the third quarter of 2026.

The allowance for credit losses, which is comprised of the ALL and reserve for unfunded loan commitments, totaled $35.5 million at September 30, 2026, compared with $36.6 million at June 30, 2026. The $1.2 million decrease in the allowance for credit losses included a $3.2 million provision for credit losses for the loan portfolio, net charge-offs of $4.6 million, a $224 thousand initial gross-up allowance related to purchased seasoned loans, and a $16 thousand reversal of provision for credit losses for unfunded loan commitments for the quarter ended September 30, 2026.

The ALL was $33.7 million, or 1.07% of total loans held for investment at September 30, 2026, compared with $34.9 million, or 1.13% at June 30, 2026.

Capital

Tangible book value per common share (non-GAAP¹) at September 30, 2026 was $14.22, compared with $14.29 at June 30, 2026. In the third quarter of 2026, tangible book value was primarily impacted by net income of $14.0 million for the third quarter, and stock-based compensation activity. This was offset by an increase in net of tax unrealized losses on available-for-sale debt securities, the Company’s common stock repurchase program activity, and cash dividends, which reduced the tangible book value per common share by $0.37, $0.14 and $0.12, respectively. Other comprehensive losses related to net of tax unrealized losses on available-for-sale debt securities increased by $11.8 million to $17.1 million at September 30, 2026, from $5.3 million at June 30, 2026. The increase in the net of tax unrealized losses on available-for-sale debt securities was attributable to non-credit related factors, including a decrease in bond prices at the long end of the yield curve and the general interest rate environment, and growth in the available-for-sale debt securities. Tangible common equity (non-GAAP¹) as a percentage of total tangible assets (non-GAAP¹) at September 30, 2026, decreased to 11.42% from 11.77% in the prior quarter, and net of tax unrealized losses on available-for-sale debt securities as a percentage of tangible common equity (non-GAAP¹) at September 30, 2026 increased to 3.8% from 1.2% in the prior quarter.

The Company’s preliminary capital ratios exceed the minimums required to be “well-capitalized” at September 30, 2026.

Stock Repurchase Program

During the third quarter of 2026, the Company repurchased 209,348 shares of its common stock at an average price of $21.81 and a total cost of $4.6 million under the stock repurchase program, compared to 102,594 shares of common stock at an average price of $19.46 and a total cost of $2.0 million in the second quarter of 2026. For the nine months ended September 30, 2026, the Company repurchased 721,857 shares of its common stock at an average price of $19.36 and a total cost of $14.0 million under the stock repurchase program. The remaining maximum number of shares authorized to be repurchased under this program was 666,215 shares at September 30, 2026.

We believe the presentation of certain non-GAAP financial measures provides useful information to assess our consolidated financial condition and consolidated results of operations and to assist investors in evaluating our financial results relative to our peers. These non-GAAP financial measures complement our GAAP reporting and are presented below to provide investors and others with information that we use to manage the business each period. Because not all companies use identical calculations, the presentation of these non-GAAP financial measures may not be comparable to other similarly titled measures used by other companies. These non-GAAP measures should be taken together with the corresponding GAAP measures and should not be considered a substitute of the GAAP measures.
