Basis of Presentation

The accompanying unaudited interim consolidated financial statements have been prepared pursuant to Article 10 of SEC Regulation S-X and other SEC rules and regulations for reporting on the Quarterly Report on Form 10-Q. Accordingly, certain disclosures required by U.S. generally accepted accounting principles (“GAAP”) are not included herein. These unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes included in Item 8. Financial Statements and Supplementary Data of the Company’s Annual Report on Form 10-K for the year ended December 31, 2024.

In the opinion of management of the Company, the accompanying unaudited interim consolidated financial statements reflect all of the adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of the consolidated financial condition and consolidated results of operations as of the dates and for the periods presented. The results of operations for the three and six months ended June 30, 2025 are not necessarily indicative of the results that may be expected for the year ending December 31, 2025.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company, including its wholly owned subsidiary, the Bank and the Bank’s wholly-owned subsidiary, BCAL OREO1, LLC. All significant intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates in the Preparation of Consolidated Financial Statements

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and

expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change are the determination of the allowance for credit losses, the fair value of assets and liabilities acquired in business combinations and related purchase price allocation, the valuation of acquired loans, the valuation of goodwill and separately identifiable intangible assets associated with mergers and acquisitions, loan sales and servicing of financial assets and deferred tax assets and liabilities.

Operating Segments

We operateone reportable segment — commercial banking. The Company hasone reporting unit, one operating segment and, consequently, a single reportable segment. The Company’s chief operating decision maker (“CODM”) is a role shared byfour executive officers, the Executive Chairman, Chief Executive Officer, President, and Chief Financial Officer. The Company’s CODM monitors revenue streams and other information regarding the products and services offered through the Company’s banking operations. The information provided to the CODM is presented on an aggregated single segment level basis, which is consistent with the accompanying consolidated financial statements presented in this Quarterly Report on Form 10-Q. The CODM evaluates the financial performance of the Company’s business by evaluating revenue streams, significant expenses, and comparing budgeted to actual results in assessing operating results and in allocating resources, with profitability only determined at a single segment level. The CODM uses revenue streams to evaluate product pricing and significant expenses to assess performance and evaluate return on assets. The CODM uses consolidated net income to benchmark the Company against its competitors. The benchmarking analysis, coupled with the monitoring of budgeted to actual results, is used in assessing performance and allocating resources. Loans, investments, and deposits provide the revenues from the Company's operations. Interest expense, provisions for credit losses, salaries and benefits, and occupancy expenses represent the significant expenses in the Company's operations. All of the Company's income and expenses are included in the accompanying consolidated statements of operations presented in this Quarterly Report on Form 10-Q. All of the Company’s operations are domestic. The Company’s assets are reflected in the accompanying consolidated balance sheets as “total assets.”

Recently Adopted Accounting Guidance

In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2023-07 Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures to require, among other things, that a public entity that has a single reportable segment provide enhanced disclosures about significant segment expenses. Significant expense categories are derived from expenses that are (1) regularly reported to an entity’s CODM, and (2) included in a segment’s reported measure of profit or loss. The disclosures should include an amount for "other segment items," reflecting the difference between (1) segment revenue less significant segment expenses, and (2) the reportable segment’s profit or loss measures. It requires that a public entity disclose the title and position of the CODM and how the CODM uses the reported measure of profit or loss to assess segment performance and to allocate resources. Further it clarifies that entities with a single reportable segment must disclose both new and existing segment reporting requirements. The ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. A public entity should apply the amendments retrospectively to all periods presented in the financial statements. The adoption of ASU 2023-07 did not have a significant impact on the consolidated financial statements.

On January 1, 2025, the Company adopted ASU No. 2023-09, Income Taxes (Topic 740) – Improvements to Income Tax Disclosures. This standard addresses requests for improved income tax disclosures from investors, lenders, creditors and other allocators of capital that use the financial statements to make capital allocation decisions. This ASU is intended to improve the transparency of tax disclosures by requiring (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction, in addition to certain other amendments intended to improve the effectiveness of income tax disclosures. The adoption of ASU 2023-09 did not have a material impact on the consolidated financial statements.

Significant Accounting Policies

Our accounting and reporting policies are described in Note 1 —Basis of Presentation and Summary of Significant Accounting Policies, of our audited consolidated financial statements included in Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2024. As of June 30, 2025, there were no significant changes to accounting policies from those disclosed in our audited consolidated financial statements included in our 2024 Form 10-K.

Recent Accounting Guidance Not Yet Effective

In October 2023, the FASB issued ASU 2023-06, Disclosure Improvements–Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative (“ASU 2023-06”). The amendments in this update modify the disclosure or presentation requirements for a variety of topics in the codification. Certain amendments represent clarifications to or technical corrections of the current requirements. The following is a summary of the topics included in the update and which pertain to the Company: 1. Statement of cash flows (Topic 230): Requires an accounting policy disclosure in annual periods of where cash flows associated with derivative instruments and their related gains and losses are presented in the statement of cash flows; 2. Accounting changes and error corrections (Topic 250): Requires that when there has been a change in the reporting entity, the entity disclose any material prior-period adjustment and the effect of the adjustment on retained earnings in interim financial statements; 3. Earnings per share (Topic 260): Requires disclosure of the methods used in the diluted earnings-per-share computation for each dilutive security and clarifies that certain disclosures should be made during interim periods, and amends illustrative guidance to illustrate disclosure of the methods used in the diluted earnings per share computation; 4. Commitments (Topic 440): Requires disclosure of assets mortgaged, pledged, or otherwise subject to lien and the obligations collateralized; and 5. Debt (Topic 470): Requires disclosure of amounts and terms of unused lines of credit and unfunded commitments and the weighted-average interest rate on outstanding short-term borrowings. For public business entities, the amendments in ASU 2023-06 are effective on the date which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective. If by June 30, 2027, the SEC has not removed the applicable requirement from Regulation and S-X or Regulation S-K, the pending content of the related amendment will be removed from the codification and will not become effective for any entity. Early adoption is not permitted and the amendments are required to be applied on a prospective basis. The Company expects the adoption of this standard will not have a material impact on its consolidated financial statements.

ASU No. 2024-03, Income Statement– Reporting Comprehensive Income-Expense Disaggregation Disclosures. In November 2024, the FASB issued ASU 2024-03 which requires disclosure in the notes to the financial statements of specified information about certain costs and expenses. In January 2025, the FASB issued ASU 2025-01, Income Statement—Reporting Comprehensive Income– Expense Disaggregation Disclosures– Clarifying the Effective Date, which amends the effective date of ASU 2024-03 to clarify that all public business entities are required to adopt the guidance in annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption of ASU 2024-03 is permitted. The Company expects the adoption of this standard will not have a material impact on its consolidated financial statements.

ASU 2025-03, Business Combinations (Topic 805) and Consolidation (Topic 810)-Determining the Accounting Acquirer in the Acquisition of a Variable Interest Entity. In May 2025, the FASB issued ASU 2025-03, which revises the guidance in ASC 805 on identifying the accounting acquirer in a business combination in which the legal acquiree is a variable interest entity (“VIE”). The ASU is intended to improve comparability between business combinations that involve VIEs and those that do not. ASU 2025-03 is effective for fiscal years beginning after December 15, 2026, including interim periods within those fiscal years. Early adoption is permitted. The amendments in ASU 2025-03 must be applied prospectively to any business combination that occurs after the initial adoption date. The Company expects the adoption of this standard will not have a material impact on its consolidated financial statements.

ASU 2025-04, Compensation—Stock Compensation (Topic 718) and Revenue from Contracts with Customers (Topic 606): Clarifications to Share-Based Consideration Payable to a Customer. In May 2025, the FASB issued ASU 2025-04 to reduce diversity in practice and improve the usefulness and operability of the guidance for share-based consideration payable to a customer in conjunction with selling goods or services. The ASU is effective for fiscal years beginning after December 15, 2026 with updates to be applied on a retrospective or modified retrospective basis. Early adoption is permitted. The Company expects the adoption of this standard will not have a material impact on its consolidated financial statements.

Recent California Tax Legislation

California Senate Bill 132 (SB 132), enacted on June 27, 2025 mandating financial institutions to adopt a single-sales-factor apportionment formula for state income and franchise tax purposes, starting with tax years beginning on or after January 1, 2025. This transition from a three-factor (equally weighted property, payroll, and sales) to a single-factor formula impacts the calculation of California taxable income and alters the marginal tax rate used by the Company in estimating its income tax provision, deferred taxes, and other comprehensive income. The Company re-measured its state deferred tax assets and liabilities as of December 31, 2024, to the new California rate of 10.84% x single sales apportionment factor and recorded a true up adjustment as a discrete tax expense item as well as updated the current CA tax apportionment used in the annual effective tax rate calculation or tax provision calculation. During the three and six months ended June 30, 2025, the Company recorded $269 thousand income tax expense as a result of these adjustments. Additionally, the Company also remeasured the state deferred maintained for OCI items as of December 31, 2024. The true up adjustment was immaterial and not recorded through tax expense for the three and six months ended June 30, 2025.

One Big Beautiful Bill Act

On July 4, 2025, President Trump signed the One Big Beautiful Bill Act (“the Act”), which includes a broad range of tax reform provisions affecting businesses. These include the permanent extension and modification of key provisions from the 2017 Tax Cuts and Jobs Act, originally set to expire at the end of 2025, as well as the expansion and accelerated phase-out of certain incentives under the 2022 Inflation Reduction Act. The Act was enacted after the reporting period, it does not affect the Company’s consolidated financial statements as of the reporting date of June 30, 2025.The Company is currently evaluating income tax implications of the Act. The Company expects the enactment of the Act will not have a material impact on its consolidated financial statements.

NOTE 2 –BUSINESS COMBINATIONS

California BanCorp Merger

On July 31, 2024 (the “Merger Date”), the Company completed its merger with CALB on the terms set forth in the Agreement and Plan of Merger and Reorganization, dated January 30, 2024, by and between the Company and CALB. Immediately following the merger of CALB with and into the Company, California Bank of Commerce, a California state-chartered bank and wholly-owned subsidiary of CALB, merged with and into the Bank. Effective with these mergers, the corporate names of Southern California Bancorp and Bank of Southern California, N.A. were changed to California BanCorp and California Bank of Commerce, N.A., respectively. The merger expanded the Company’s footprint into Northern California and provided an opportunity for building scale and increasing market share through complementary business models with a strong deposit base. The combined company retained the banking offices of both banks, adding CALB’sone full-service bank branch and itsfour loan production offices in Northern California to the Bank’s 13 full-service bank branches located throughout the Southern California region.

The Merger was an all-stock transaction valued at approximately $216.6 million based on a closing price of the Company’s common stock of $15.79 on July 31, 2024. Under the terms of the Agreement and Plan of Merger and Reorganization, each outstanding share of CALB common stock was exchanged for the right to receive 1.590 shares of the Company’s common stock, resulting in the net issuance of approximately 13,497,091 shares, with cash (without interest) paid in lieu of fractional shares. An additional 82,364 net shares were issued to CALB’s non-continuing directors, officers and employees where the Company had granted and fully accelerated replacement restricted stock units totaling 123,123 shares with a fair value of $1.9 million, of which $825 thousand related to pre-combination vesting and was included in purchase consideration and $1.1 million related to post-combination vesting and was recognized in expense of the combined company at merger closing. The Company also granted replacement awards for 295,512 unvested restricted stock units, with a fair value of $4.7 million, to CALB’s continuing directors, officers and employees. Of this amount, $1.3 million related to pre-combination vesting and was included in purchase consideration and $3.4 million related to post-combination vesting and will be recognized in expense of the combined company over the remaining vesting period. In addition, the Company settled for cash all in-the-money CALB stock options immediately prior to the merger in the amount of $1.7 million.

The Company accounted for the Merger using the acquisition method of accounting in accordance with ASC 805, Business Combinations and accordingly, the acquired assets and assumed liabilities of CALB were recorded at their respective fair values on the Merger Date and subsequently updated to reflect newly obtained information. In many cases, the determination of fair value required management to make estimates about discount rates, expected future cash flows, market conditions and other future events that are highly subjective in nature and subject to change. While the Company believes that the information available on the Merger Date provided a reasonable basis for estimating fair value, additional or new information during the measurement period pertaining to facts and circumstances that existed as of the Merger Date that, if known, may materially impact the initial valuations would result in changes to the preliminary estimated fair value amounts. The measurement period ends on the earlier of one year after the Merger Date or the date the Company concludes that all necessary information about the facts and circumstances that existed as of the Merger Date have been obtained. Adjustments recorded during this period are recognized in the current reporting period. The following table summarizes adjustments to goodwill subsequent to July 31, 2024.

The Company recorded adjustments related to the Merger resulting in a decrease to goodwill of $1.6 million within the one-year measurement period subsequent to the Merger Date of July 31, 2024. These net of tax adjustments included the fair value of acquired trade name, a true-up of the acquired low-income housing tax credit investments, recoveries on acquired PCD loans previously charged-off prior to the Merger, and deferred tax adjustments related to the finalization of CALB’s final tax return and CALB state net operating losses that cannot be utilized post-merger.

The following table represents the allocation of the purchase consideration to the preliminary fair value of assets acquired and liabilities assumed of CALB, subject to finalization, as of July 31, 2024, as adjusted:

(1)Represents 5,596 unvested restricted stock units of non-continuing CALB directors that were automatically fully vested and converted under the merger agreement and 71,840 of unvested restricted shares (replacement awards) for non-continuing executives and employees that were accelerated and fully vested. The portion of the fair value of these awards attributable to pre-combination vesting is included as a component of purchase consideration. The portion of the fair value of these awards attributable to post-combination vesting (See #2 below) was reflected in expense of the combined company upon merger closing.

(2)Represents the fair value of the 77,436 CALB restricted stock units (replacement awards) that were accelerated for non-continuing directors, executives and employees that was attributable to post-combination vesting. Upon acceleration,51,801 net CALB shares were then converted into the right to receive the Company’s common stock after 25,635 of CALB shares were surrendered by certain executives and employees to pay for taxes. The portion of the fair value of these awards attributable to post-combination vesting was recognized as an expense of the combined company upon merger closing.

(3)Included in this amount is $472 thousand related to 31,355 restricted stock units that fully vested due to change in control agreements (double trigger) held by four executives that are no longer employed by the Company upon closing of the Merger.

(4)Represents the payment of (a) $1.3 million for 283,641 vested stock options at a weighted average exercise price of $18.22 and (b) $82 thousand for 92,685 unvested stock options at a weighted average price of $19.03 attributable to pre-combination vesting based on the $22.98 Option Cashout Price. An additional $284 thousand was paid for the portion of unvested stock options attributable to post-combination vesting and was recognized as an expense of the combined company upon merger closing. There were 65,785 unvested stock options at a weighted average price of $23.81 that were out-of-the-money at July 31, 2024 and excluded from stock option consideration as they were cancelled under the terms of the merger agreement.

(5)Represents the fair value of 185,878 unvested restricted stock units (replacement awards) for continuing executives and employees attributable to pre-combination vesting. A forfeiture rate of 3% was applied in determining share-based awards expected to vest.

Goodwill represents the excess of the purchase consideration over the fair value of the net assets acquired and was primarily attributable to the expected synergies and the expansions of economies of scale and new territory from combining the operations of the Company and CALB. Goodwill is not deductible for U.S. income tax purposes and is not amortized. Rather, goodwill is tested for impairment annually, or more frequently if events or changes in circumstances indicate that it might be impaired, by comparing its carrying value to the reporting unit’s fair value.

The following methods and assumptions were used to estimate the fair value of significant financial instruments:

Cash and cash equivalents. The carrying amounts of cash and cash equivalents approximates fair value due to the short-term nature and liquidity of these instruments.

Debt securities available for sale. The fair values of debt securities was determined by obtaining quoted prices on nationally recognized securities exchanges or matrix pricing, which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted prices for specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities.

Loans held for investment. The Company utilized an independent third-party to assist in valuing loans held for investment. The fair value of the acquired loan portfolio was determined by segregating the portfolio into three groups: PCD loans, non-accruing PCD loans and all other loans (“non-PCD loans”). These three categories were further segmented by loan type. For non-PCD loans, the fair value for each individual loan segment consisted of the principal balance adjusted for both an interest component and credit component, which was calculated on a pool basis using a discounted cash flow approach. The discount rates utilized for this approach were based on a weighted average cost of capital, considering the cost of equity and cost of debt and other factors. Expected loan cash flows incorporated default, loss, and prepayment rates based on industry standards.

PCD loans are defined as loans that as of the date of acquisition have experienced a more-than-insignificant deterioration in credit quality since origination, as determined by an acquirer's assessment. The initial amortized cost basis for PCD loans represents the fair value of the loans plus an allowance for credit losses at the date of acquisition. The fair value for PCD loans incorporated market-based loss rates used to estimate expected life of loan credit losses. The noncredit discount resulting from the acquired PCD loans was allocated to each individual asset. At the acquisition date, the initial allowance for credit losses was determined on a collective basis and was allocated to the individual PCD loans. The initial allowance for credit losses for PCD loans includes expected recoveries of amounts previously charged off and expected to be charged off by the Company. The non-credit discount, after the adjustment for the allowance for credit losses, is accreted to interest income using the interest method based on the effective interest rate at acquisition date.

The following table presents the composition of PCD loans as of the acquisition date:

Bank owned life insurance. The carrying amount of bank owned life insurance approximates fair value given the liquidity of these instruments.

Deferred tax assets, net. The fair value of acquired deferred tax assets and liabilities represents the estimated amount of tax benefits for acquired assets and assumed liabilities that the Company expects to be recognized on its tax returns. The Company utilized an effective tax rate of 29.56% in determining the fair value on deferred taxes, net.

Core deposit intangible. The fair value of the core deposit intangible was determined by evaluating the underlying characteristics of the deposit relationships, including estimated customer attrition, projected deposit interest rates, net maintenance cost of the deposit base, and costs of alternative funding. The value of the after-tax savings on cost of funds is the present value over an estimated fifty-year horizon, using the discount rate applicable to the asset. The core deposit intangible will be amortized over the expected account retention period, which was originally estimated at approximately 10 years or 120 months. The core deposit intangible will be evaluated periodically to determine the reasonableness of the projected amortization period by comparing actual deposit retention to projected retention.

Deposits. The fair values of demand and savings deposits represent the amount payable on demand at acquisition date. The fair value of time deposits was determined using a discounted cash flow approach, which involved determining the present value of the required contractual payments over the remaining life of the time deposits using market-based interest rates.

Borrowings. The fair value of subordinated notes was determined using a discounted cash flow approach, which involved determining the present value of required contractual payments over the estimated life of the notes, factoring in expected redemption dates, discounted at a rate that incorporated market-based interest rates, inclusive of a credit spread and liquidity premium.

NOTE 3 -INVESTMENT SECURITIES

Debt Securities

Debt securities have been classified as either held-to-maturity or available-for-sale in the consolidated balance sheets according to management’s intent. The amortized cost of held-to-maturity debt securities and their approximate fair values at June 30, 2025 and December 31, 2024 were as follows:

The amortized cost of available-for-sale debt securities and their approximate fair values at June 30, 2025 and December 31, 2024 were as follows:

During the three and six months ended June 30, 2025 and 2024, there were no transfers between held-to-maturity and available-for-sale debt securities.

At June 30, 2025 and December 31, 2024, there were no holdings of securities of any one issuer, other than the U.S. Government and its agencies, in an amount greater than 10% of our shareholders’ equity.

Accrued interest receivable on held-to-maturity and available-for-sale debt securities totaled $958 thousand and $879 thousand at June 30, 2025 and December 31, 2024, respectively, and is included within accrued interest receivable and other assets in the consolidated balance sheets. Accrued interest receivable is excluded from the ACL.

At June 30, 2025, available-for-sale debt securities with an amortized cost of $2.9 million were pledged to the Federal Reserve Bank (“Federal Reserve”) as collateral for a secured public deposits and for other purposes as required by law or contract provisions, in addition to held-to-maturity debt securities with an amortized cost of $53.1 million were pledged as collateral for a secured line of credit with the Federal Reserve. See Note 8 –Borrowing Arrangements for additional information regarding the FHLB and Federal Reserve secured lines of credit. The Company also pledged $15.8 million available-for-sale debt securities to another financial institution to support the collateralization requirement against certain customers’ standby lines of credit.

Contractual Maturities

The amortized cost and estimated fair value of all held-to-maturity and available-for-sale debt securities as of June 30, 2025 by contractual maturities are shown below. Expected maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

Realized Gains and Losses

There wereno gross realized gains and losses for sales and calls of available-for-sale debt securities during the three and six months ended June 30, 2025 and 2024.

Unrealized Gains and Losses

The gross unrealized losses and related estimated fair values of all available-for-sale debt securities aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position at June 30, 2025 and December 31, 2024 are summarized as follows:

As of June 30, 2025, the Company had a total of 86 available-for-sale debt securities in a gross unrealized loss position totaling $6.4 million, including 63 securities with total gross unrealized losses of $5.4 million that had been in a continual loss position for twelve months and longer. As of December 31, 2024, the Company had a total of 89 available-for-sale debt securities in a gross unrealized loss position totaling $9.6 million, including 64 securities with total gross unrealized losses of $7.6 million that had been in a continual loss position for twelve months and longer. Such unrealized losses on these investment securities have not been recognized into income.

Unrealized losses on available-for-sale debt securities are recognized in shareholders’ equity as accumulated other comprehensive loss. At June 30, 2025, the Company had a net unrealized loss on available-for-sale debt securities of $5.3 million, or $3.7 million net of tax in accumulated other comprehensive loss, compared to a net unrealized loss of $9.4 million, or $6.6 million net of tax in accumulated other comprehensive loss, at December 31, 2024.

Allowance for Credit Losses on Debt Securities

For available-for-sale debt securities with unrealized losses, management considered the financial condition of the issuer and the Company’s intent and ability to retain the investment for a period of time sufficient to allow for any anticipated recovery in fair value. The Company’s available-for-sale debt securities consisted of U.S. Treasury, U.S. government and agency and government sponsored enterprise securities, and municipals, which historically have had limited credit loss experience. In addition, the Company reviewed the credit rating of the municipal securities. At June 30, 2025, the total fair value of taxable municipal and tax exempt bank-qualified municipal securities was $928 thousand and $829 thousand, respectively. At June 30, 2025, all of these securities were rated AA and above. At December 31, 2024, the total fair value of taxable municipal and tax exempt bank-qualified municipal securities was $909 thousand and $826 thousand, respectively. At December 31, 2024, all of these securities were rated AA and above.

At June 30, 2025,61 held-to-maturity debt securities with fair values totaling $47.5 million had gross unrecognized losses totaling $5.6 million, compared to 61 held-to-maturity debt securities with fair values totaling $47.8 million had gross unrecognized losses totaling $5.5 million at December 31, 2024. The Company has the intent and ability to hold the securities classified as held-to-maturity until they mature, at which time the Company will receive full value for the securities. At June 30, 2025 and December 31, 2024, fair values of held-to-maturity debt securities rated AA and above totaled $44.4 million and $44.7 million, respectively and those rated AA- totaled $3.2 million and $3.2 million, respectively.

Management evaluates securities in an unrealized loss position at least on a quarterly basis, and determined that the unrealized losses at June 30, 2025 and 2024 related to each investment were primarily attributable to factors other than credit related, including changes in interest rates driven by the Federal Reserve’s policy to fight against inflation and general volatility in market conditions. As such, the Company applied a zero credit loss assumption for these securities andno provision for credit losses was recorded for held-to-maturity or available-for-sale debt securities during the three and six months ended June 30, 2025 and 2024.

Restricted Stock

As a member of the Federal Reserve System, the Company must hold stock of the Federal Reserve in an amount equal to 3% of the Company’s common stock and additional paid-in capital. In addition, as a member of the Federal Home Loan Bank (“FHLB”) of San Francisco, the Company is required to own stock of the FHLB based on the Company’s outstanding mortgage assets and outstanding advances from the FHLB.

The table below summarizes the Company’s restricted stock investments at June 30, 2025 and December 31, 2024:

During the three and six months ended June 30, 2025, the Company purchased $13 thousand and $29 thousand of Federal Reserve stock, respectively, and there wereno purchases of FHLB stock.

During the three and six months ended June 30, 2024, the Company purchased $12 thousand and $23 thousand, respectively, of Federal Reserve stock, and there were $820 thousand and $820 thousand, respectively, of purchases of FHLB stock.

Other Equity Securities Without A Readily Determinable Fair Value

The Company also has equity securities in the form of capital stock invested intwo different banker’s bank stocks which totaled $819 thousand at both June 30, 2025 and December 31, 2024. These equity securities are reported in accrued interest receivable and other assets in the consolidated balance sheets. At June 30, 2025 and December 31, 2024, the Company evaluated the carrying value of these equity securities and determined that they were not impaired. During the three and six months ended June 30, 2025 and 2024, there wereno losses related to changes in the fair value of these equity securities.

The Company has other equity investments and investments in a technology venture capital fund focused on the intersection of fintech and community banking. These equity investments represent variable interest entities (“VIEs”), however the Company is not the primary beneficiary. The Company’s maximum exposure to loss related to its investments in these unconsolidated VIEs is limited to the carrying value of each of the investments plus any unfunded capital commitments. At June 30, 2025 and December 31, 2024, the balance of these investments, which is included in accrued interest receivable and other assets in the consolidated balance sheets, was $8.4 million and $7.1 million, respectively. Total unfunded capital commitments for these investments were $6.6 million at June 30, 2025. These equity securities are measured using the equity method of accounting when the Company’s ownership interest in such investments exceeds 5%, or carried at cost less impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or similar investments of the same issuer. Cash distributions that are considered a return of capital are recorded as a reduction of the Company’s investment. During the three and six months ended June 30, 2025, the Company made $398 thousand and $330 thousand, respectively, of net capital contributions to these equity investments. During the three and six months ended June 30, 2024, the Company made $170 thousand and $97 thousand of net capital contributions to these equity investments. At June 30, 2025 and December 31, 2024, the Company evaluated the carrying value of these equity investments and determined they were not impaired.

During the three and six months ended June 30, 2025 and 2024, there wereno losses recognized related to changes in the fair value.

The Company has also invested in and acquired limited partnerships that operate affordable housing projects that qualify for and have received an allocation of federal and/or state low-income housing tax credits. These investments represent VIEs, however the Company is not the primary beneficiary. The Company’s maximum exposure to loss related to its investments in these unconsolidated VIEs is limited to the carrying amount of the investment and previously recorded tax credits which remain subject to recapture by taxing authorities based on compliance features required to be met at the project level. At June 30, 2025 and December 31, 2024, the net amortized balance of these investments was $5.2 million and $5.7 million, respectively, and is included in accrued interest and other assets in the consolidated balance sheets. The unfunded portion of these investments totaled $1.2 million and $1.8 million at June 30, 2025 and December 31, 2024, respectively, and is included in accrued interest payable and other liabilities in the consolidated balance sheets.

The following table presents activity in qualifying low income housing projects for the three and six months ended June 30, 2025 and 2024 follows:

At June 30, 2025 and December 31, 2024, the Company evaluated the carrying value of these tax credit equity investments and determined they were not impaired, andno loss was recognized related to changes in the fair value.

NOTE 4 -LOANS AND ALLOWANCE FOR CREDIT LOSSES

Loans Held for Investment

The Company’s loan portfolio consists primarily of loans to borrowers within the California market. Although the Company seeks to avoid concentrations of loans to a single industry or based upon a single class of collateral, real estate and real estate associated businesses are among the principal industries in the Company’s market area. The Company’s loan portfolio in real estate secured credit represented 79% and 77% of total loans at June 30, 2025 and December 31, 2024, respectively. The Company also originates SBA loans either for sale to institutional investors or for retention in the loan portfolio. Loans identified as held for sale are carried at the lower of cost or market value and separately designated as such in the consolidated financial statements. A portion of the Company’s revenues are from origination of loans guaranteed by the SBA under its various programs and sale of the guaranteed portions of the loans. Funding for these loans depends on annual appropriations by the U.S. Congress.

The composition of the Company’s loan portfolio at June 30, 2025 and December 31, 2024 was as follows:

(1)Loans held for investment includes net unearned fees of $2.2 million and $1.8 million and net unearned discounts on acquired loans of $46.1 million and $58.5 million at June 30, 2025 and December 31, 2024, respectively. The Company recognized $5.6 million and $386 thousand for the three months ended June 30, 2025 and 2024, respectively. The Company recognized $10.8 million and $129 thousand in interest accretion for acquired loans for the six months ended June 30, 2025 and 2024, respectively.

The Company has pledged $2.15 billion of loans with the FHLB under a blanket lien, of which an unpaid principal balance of $1.32 billion was considered as eligible collateral under this secured borrowing arrangement and loans with an unpaid principal balance totaling $353.1 million were pledged as collateral under a secured borrowing arrangement with the Federal Reserve as of June 30, 2025. See Note 8 –Borrowing Arrangements for additional information regarding the FHLB and Federal Reserve secured lines of credit.

Loans Held for Sale

At June 30, 2025, the Company had loans held for sale totaling $6.1 million, consisting of SBA 7(a) loans. At December 31, 2024, loans held for sale totaled $17.2 million, consisting of $10.3 million SBA 7(a) loans and $6.9 million C&I loans transferred from loans held for investment. The Company accounts for loans held for sale at the lower of carrying value or fair value. At June 30, 2025 and December 31, 2024, the fair value of loans held for sale totaled $6.4 million and $17.9 million, respectively.

Credit Quality Indicators

The Company categorizes loans using risk ratings based on relevant information about the ability of borrowers to service their debt such as current financial information, historical payment experience, collateral adequacy, credit documentation, and current economic trends, among other factors. Larger, non-homogeneous loans such as CRE and C&I loans are analyzed individually for risk rating assessment. For purposes of risk classification, 1-4 Family Residential loans for investment purposes are evaluated with CRE loans. This analysis is performed on an ongoing basis as new information is obtained. The Company uses the following definitions for risk ratings:

Pass - Loans classified as pass include loans not meeting the risk ratings defined below.

Special Mention- Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date.

Substandard- Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected.

Doubtful - Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.

Loss - Loans classified as loss are considered uncollectible and of such little value that their continuance as bankable assets is not warranted. This classification does not mean that the asset has absolutely no recovery or salvage value, but rather that it is not practical or desirable to defer writing off this basically worthless asset even though partial recovery may be affected in the future.

The risk category of loans by class of loans and origination year as of June 30, 2025 follows:

Collateral Dependent Loans

Collateral dependent loans are loans for which the repayment is expected to be provided substantially through the operation or sale of the collateral and the borrower is experiencing financial difficulty. Estimates for costs to sell are included in the determination of the ACL when liquidation of the collateral is anticipated. In cases where the loan is well secured and the estimated value of the collateral exceeds the amortized cost of the loan, no ACL is recorded.

A summary of collateral dependent loans by collateral type as of June 30, 2025 and December 31, 2024 follows:

Allowance for Credit Losses - Loans

The ACL consists of: (i) a specific allowance established for CECL on loans individually evaluated, (ii) a quantitative allowance for current expected loan losses based on the portfolio and expected economic conditions over a reasonable and supportable forecast period that reverts back to long-term trends to cover the expected life of the loan, (iii) a qualitative allowance including management judgment to capture factors and trends that are not adequately reflected in the quantitative allowance, and (iv) the ACL for off-balance sheet credit exposure for unfunded loan commitments.

For prepayment and curtailment rates, the Company used its own historical quarterly prepayment and curtailment experience covering the period starting February 2021 through May 2025 to estimate the ACL. The Company used the probability-weighted two-scenario forecasts, representing a base-case scenario and one downside scenario, to estimate the ACL. The Company utilized economic forecasts released by Moody’s Analytics during the second week of June 2025. Other sources of economic forecasts and meeting minutes of the Federal Open Market Committee (“FOMC”) meeting were also considered by the Company when determining the scenario weighting. At June 30, 2025, modest adjustments were made to the Moody’s June 2025 U.S. baseline forecast based on a reassessment of policy actions, new data and market movements. Real GDP growth remained weak in the near term. The growth for 2025 is weaker than the March 2025 forecast. Moody’s economic forecast maintained its projection of 25 basis point interest rate cuts in both September and December 2025. The underlying assumptions in the Moody’s baseline economic forecasts remained consistent in the expectation that the Federal Reserve is expected to gradually reduce the policy rate to its neutral level of 3% by late 2026.

Moody's updated its baseline forecast in June 2025, decreasing the real GDP projection from the previous quarter's estimate, bringing it to an annual average of 1.5% for 2025. Growth in 2026 was revised downward by 0.3% from 1.4%. For 2027, the national GDP was also revised downward to 1.8%. The Conference Board’s forecast for 2025 GDP was revised downward to 1.6% in June 2025, down from 2.0% previously and in line with Moody’s Baseline scenario of 1.5%.

Moody’s downside scenario forecasted the economy to fall into a mild recession starting in the third quarter of 2025. The decline lasts for three quarters, and the peak-to-trough decline in real GDP is 1.0%. Despite the recession in the third quarter of 2025, rising inflation causes the Fed to raise the fed funds rate. It resumes easing in the fourth quarter of 2025 as the recession persists, and the Fed funds rate falls below the baseline at that point. The weakening in the economy causes the unemployment rate to rise in the third quarter of 2025. Moody’s downside scenario forecasted for California suggested the state unemployment rate would reach 7.1% in the second quarter of 2026 from the weakening economy.

Moody’s economic forecasts for California suggested California gross state product (“GSP”) growth of 1.6% in 2025, that continues to decrease to 1.5% in 2026. The report forecasts 2025 California unemployment at 5.1%, and remaining at 5.1% in 2026. Beacon Economics forecasted the California unemployment rate upward to 5.7% from the third quarter of 2025 and topping at 5.8% for the following three quarters.

The other California economic forecasts, like GSP for the construction sector, California Home Price Index (“HPI”) and Personal Consumption Expenditure (“PCE”), used in the ACL calculation were mixed in the baseline and downside scenarios. These varied changes in key economic forecasts for California are expected to have a mixed impact on the Company's ACL.

Based on the above reviews and analyses, the Company decided to keep using the two probability-weighted scenario forecasts. The recommended weightings are based on the FOMC maintaining the federal funds rate unchanged for the fourth consecutive meeting in June 2025, amid expectations of rising inflation and slowing economic growth ahead, while still pointing to two reductions later this year. Uncertainty about the economic outlook has diminished, but remains elevated, unemployment rate remains low, and labor market conditions remain solid. The Company opts to utilize solely the base-case scenario for the ACL model; however, given recent heightened domestic and geopolitical uncertainty, uncertainty around the new administration and tariff policy, a rising inflation level that is still considerably above the Fed’s 2.0% target rate, and slowing GDP growth projection, the Company believes it is prudent to assign a weighting to a downside scenario (S2) that considers the potential for rising inflation. Inflation is the most difficult economic variable to predict, as it is subject to a variety of factors and there are limited tools to control it. A new presidential administration has brought changes in U.S.

economic policy, the effects of which are unknown and may potentially lead to higher inflation, as could other domestic and geopolitical developments. Incorporating the S2 scenario in our ACL model provides a hedge against the potential for increasing inflation in an uncertain economic environment.

During the second quarter of 2025, the Company updated its historical prepayment and curtailment rates analysis, which reflected a slight decrease in prepayment rates and curtailment rates from the first quarter of 2025 primarily due to lower payoffs and paydowns.

Accrued interest receivable on loans, totaled $9.7 million and $11.7 million at June 30, 2025 and December 31, 2024, respectively, and is included within accrued interest receivable and other assets in the accompanying consolidated balance sheets. Accrued interest receivable is excluded from the ACL.

Allowance for Credit Losses - Unfunded Loan Commitments

The allowance for credit losses on unfunded credit commitments is maintained at a level that management believes to be sufficient to absorb estimated expected credit losses related to unfunded credit facilities. The Company evaluates the loss exposure for unfunded loan commitments to extend credit following the same principles used for the ACL, with consideration for experienced utilization rates on client credit lines and the inherently lower risk of unfunded loan commitments relative to disbursed commitments. The Company recognized a provision for (reversal of) credit losses for unfunded loan commitments of $29 thousand and $(589) thousand for the three and six months ended June 30, 2025, respectively. There was a $97 thousand and $114 thousand reversal of credit losses for unfunded loan commitments for the three and six months ended June 30, 2024, respectively. The provision for (reversal of) credit losses for unfunded loan commitments is included in (reversal of) provision for credit losses in the consolidated statements of operations. The reserve for unfunded loan commitments was $2.5 million and $3.1 million at June 30, 2025 and December 31, 2024, respectively. The reserve for unfunded loan commitments is included in accrued interest payable and other liabilities in the consolidated balance sheets.

A summary of the changes in the ACL for loans and unfunded commitments for the periods indicated follows:

A summary of changes in the ALL by loan portfolio segment for the periods indicated follows:

Other Real Estate Owned (“OREO”), Net

Real estate acquired by foreclosure or deed in lieu of foreclosure is recorded at fair value less costs to sell at the date of foreclosure, establishing a new cost basis by a charge to the ACL, if necessary. The Company hadzero and $4.1 million of foreclosed assets at June 30, 2025 and December 31, 2024, respectively. During the three and six months ended June 30, 2025, the Company sold $4.1 million of OREO and recognized a loss on sale of $862 thousand.

NOTE 5 -TRANSFERS AND SERVICING OF FINANCIAL ASSETS

The Company has originated loans that are serviced for others, including loans partially guaranteed by the SBA, some of which have been sold in the secondary market, as well as CRE loans and C&I loans participated with various other financial institutions and special purpose vehicle (“SPV”) participations for the Main Street loans. Loans sold and serviced for others are accounted for as sales and are therefore not included in the accompanying consolidated balance sheets. Loans serviced for others totaled $144.4 million and $138.0 million at June 30, 2025 and December 31, 2024, respectively. This includes SBA loans serviced for others of $37.4 million and $33.2 million at June 30, 2025, and December 31, 2024, for which there was a related servicing asset of $406 thousand and $344 thousand, respectively.

Consideration for each SBA loan sale includes the cash received and a related servicing asset. The Company receives servicing fees ranging from 0.25% to 1.00% for the services provided over the life of the loan. The servicing asset is based on the estimated fair value of these future cash flows to be collected. The risks inherent in SBA servicing assets primarily relates to accelerated prepayment of loans in excess of what was originally modeled driven by changes in interest rates and a reduction in the estimated future cash flows.

The servicing asset activity includes additions from loan sales with servicing retained, and reductions from amortization as the serviced loans are repaid and servicing fees are earned. The SBA servicing asset is reported in accrued interest receivable and other assets in the consolidated balance sheets.

A summary of changes in the SBA servicing asset for the three and six months ended June 30, 2025 and 2024 follows:

(1) Included accelerated amortization of $17 thousand and $80 thousand for the three months ended June 30, 2025 and 2024, respectively, respectively. Included accelerated amortization of $46 thousand and $90 thousand for the six months ended June 30, 2025 and 2024, respectively.

SBA 7(a) loans sold during the six months ended June 30, 2025 totaled $9.0 million resulting in total gains on sale of SBA loans of $577 thousand. SBA 7(a) loans sold during the six months ended June 30, 2024 totaled $6.3 million resulting in total gains on sale of SBA loans of $415 thousand.

The fair value of the servicing asset approximated the carrying value at June 30, 2025 and December 31, 2024. The significant assumptions used in the valuation of the SBA servicing asset at June 30, 2025 and December 31, 2024 included:

The following table presents the components of net servicing fees, included in servicing and related fees (expense) on loans, net in the consolidated statements of operations, for the three and six months ended June 30, 2025 and 2024:

NOTE 6 -GOODWILL AND OTHER INTANGIBLE ASSETS

Goodwill, the excess purchase price over the fair value of all identifiable assets and liabilities acquired, totaled $110.9 million and $111.8 million at June 30, 2025 and December 31, 2024, respectively. Goodwill is reviewed for impairment at least annually during the fourth quarter of each fiscal year. On an ongoing basis, we qualitatively assess whether current events or circumstances warrant the need for an interim quantitative assessment of goodwill impairment. We also monitor fluctuations in our stock price.

The Company performed a qualitative assessment for the annual impairment review at December 31, 2024, and as a result of that assessment had determined that there has beenno impairment to goodwill. There were no triggering events during the second quarter of 2025 that caused management to evaluate goodwill for a quantitative impairment analysis as of June 30, 2025.

The following table presents changes in the carrying amount of goodwill for the three and six months ended June 30, 2025 and 2024:

(1)During the three months ended June 30, 2025, the goodwill adjustments were related to recoveries on acquired PCD loans previously charged-off prior to the CALB merger. During the six months ended June 30, 2025, the goodwill adjustments were related to a true-up of the low-income housing tax credit investments acquired from the CALB merger, offset by CALB state net operating losses that cannot be utilized post-merger and recoveries on acquired PCD loans previously charged-off prior to the CALB merger.

Core deposit intangibles are amortized over remaining periods of 3.5 to 9.1 years. Trade name is amortized over a remaining period of 1.1 years. As of June 30, 2025, the weighted-average remaining amortization period for intangible assets was approximately 8.8 years.

The Company performs the annual impairment analysis for the intangibles assets at least annually during the second half of each fiscal year. The Company evaluated current conditions and concluded there had been no significant changes in the economic environment or future projections since the annual intangible assets impairment test performed at November 30, 2024 and therefore, believes that there was no impairment as of June 30, 2025. Management will continue to evaluate the economic conditions at future reporting periods for applicable changes. The following table presents the changes in intangible assets for the three and six months ended June 30, 2025 and 2024.

Future estimated amortization expense is as follows:

NOTE 7 -DEPOSITS

The Company is a participant in the Certificate of Deposit Account Registry Service (“CDARS”), IntraFi Network Insured Cash Sweep (“ICS”), and Reich & Tang Deposit Solutions (“R&T”) network. The Company receives an equal dollar amount of deposits (“reciprocal deposits”) from other participating banks in exchange for the deposits we place into the networks to fully qualify large customer deposits for FDIC insurance. These reciprocal deposits are not required to be treated as brokered deposits up to the lesser of 20% of the Bank’s total liabilities or $5 billion.

As of June 30, 2025, reciprocal deposits decreased to $730.6 million, representing 22.1% of total deposits and 21.7% of Bank’s total liabilities, compared to $754.4 million, or 22.2% of total deposits at December 31, 2024. The excess over 20% increased the Bank’s wholesale funding to total assets ratio and net non-core funding dependence ratio. These two ratios were still within the Bank's internal policy limit.

Time deposits that exceeded the FDIC insurance limit of $250,000 amounted to $83.6 million and $80.6 million as of June 30, 2025 and December 31, 2024, respectively. Brokered time deposits totaled $3.8 million and $121.1 million as of June 30, 2025 and December 31, 2024, respectively.

The Company participates in a state public deposits program that allows it to receive deposits from the state or from political subdivisions within the state in amounts that would not be covered by the FDIC. This program provides a stable source of funding to the Company. As of June 30, 2025 and December 31, 2024, total collateralized deposits, including the deposits of State of California and their public agencies, were $26.5 million and $25.1 million, respectively, and were collateralized by letters of credit issued by the FHLB under the Company’s secured line of credit with the FHLB. See Note 8 –Borrowing Arrangements for additional information regarding the FHLB secured line of credit.

At June 30, 2025, the scheduled maturities of time deposits were as follows:

During the third quarter of 2024, the Company issued 13,579,454 shares of common stock, including net shares for the settlement of accelerated restricted stock units, in connection with the Merger (refer to Note 2 -Business Combinations for additional information).

NOTE 10 -EARNINGS PER SHARE (“EPS”)

The following is a reconciliation of net income and shares outstanding to the income and number of shares used to compute EPS for the three and six months ended June 30, 2025 and 2024:

For the three months ended June 30, 2025 and 2024, there were 227,638 and 145,422 restricted stock units andzero and 8,000 stock options, respectively, that were not included in the computation of diluted earnings per share, because they were anti-dilutive. For the six months ended June 30, 2025 and 2024, there were 144,414 and 73,306 restricted stock units andzero and 4,000 stock options, respectively, that were not included in the computation of diluted earnings per share, because they were anti-dilutive.

NOTE 11 -RELATED PARTY TRANSACTIONS

In the ordinary course of business, the Bank has made loans to certain directors, their related interests with which they are associated, and beneficial owners with more than 5% of any class of the Company’s voting securities. The balance of these loans outstanding and activity in related party loans for the three and six months ended June 30, 2025 and 2024 follows:

Directors and related interests deposits at June 30, 2025 and December 31, 2024, amounted to approximately $49.5 million and $62.9 million, respectively.

The Company leases its Ramona branch office from a beneficial owner who holds more than 5% of the Company’s voting securities and is a former member of the Company’s Board of Directors under an operating lease expiring in 2027 on terms considered to be prevailing in the market at the time of the lease. Total lease expense for the three and six months ended June 30, 2025 was $11 thousand and $22 thousand, respectively. Total lease expense for the three and six months ended June 30, 2024 was $11 thousand and $22 thousand, respectively, and future minimum lease payments under the lease were $85 thousand and $107 thousand as of June 30, 2025 and December 31, 2024, respectively.

In April 2022, the holding company entered into an investment commitment of $2.0 million with the Castle Creek Launchpad Fund I (“Launchpad”). A director of the Company is a member of the Investment

Committee for Launchpad. At June 30, 2025 and December 31, 2024, total capital contributions made to this investment were $1.3 million and $1.2 million, respectively.

NOTE 12 -COMMITMENTS AND CONTINGENCIES

In the ordinary course of business, the Company enters into financial commitments to meet the financing needs of its customers. These financial commitments include commitments to extend credit and standby letters of credit. Those instruments involve, to varying degrees, elements of credit and interest rate risk not recognized in the Company’s financial statements.

Commitments to extend credit are agreements to lend to a client as long as there is no violation of any condition established in the contract. Since many of the commitments are expected to expire without being drawn upon, the total amounts do not necessarily represent future cash requirements. The Company evaluates each client’s credit worthiness on a case-by-case basis. Collateral may or may not be required based on management’s credit evaluation of the customer. The majority of the Company’s commitments to extend credit and standby letters of credit are secured by real estate.

The Company’s exposure to loan loss in the event of nonperformance on commitments to extend credit and standby letters of credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments as it does for loans reflected in the consolidated financial statements.

The Company had the following outstanding financial commitments whose contractual amount represents potential credit risk at June 30, 2025 and December 31, 2024:

The Company entered into Supplemental Executive Retirement Plan (“SERP”) agreements to provide a 10-year benefit to certain key officers upon their retirement. Under these agreements, the annual benefits range from $20 thousand to $75 thousand. In connection with the Merger, the Company assumed all SERP agreements from CALB, under the same terms and conditions, with the exception of the Chief Executive Officer whose maximum “targeted benefit amount” increased to 30% of the average of his three highest calendar years of base salary as part of his employment agreement with the Company. The estimated present value of future benefits to be paid is being accrued over the period from the effective date of the agreements until the expected retirement dates of the participants. The expense incurred for these agreements for the three and six months ended June 30, 2025 was $247 thousand and $494 thousand, respectively. The expense incurred for these agreements for the three and six months ended June 30, 2024 was $81 thousand and $162 thousand, respectively. The Company is a beneficiary of life insurance policies that have been purchased as a method of financing the obligated benefits under these agreements.

In the normal course of business, the Company is named or threatened to be named as a defendant in various legal actions. The ultimate outcome with respect to these legal matters and claims cannot be determined at this time and the Company believes that liability, if any, is not likely to be material to the consolidated balance sheets or consolidated statements of operations.

NOTE 13 -STOCK-BASED COMPENSATION PLAN

In contemplation of the holding company reorganization, in November 2019 the Company’s Board of Directors adopted the Southern California Bancorp 2019 Omnibus Equity Incentive Plan (the “2019 Plan”). The 2019 Plan was approved by shareholders in April 2020 with a maximum number of shares of common stock that may be issued or paid out under the plan of 2,200,000. In addition, upon the completion of the bank holding company reorganization in 2020, the Bank’s 2001 Stock Option Plan and 2011 Omnibus Equity Incentive Plan were terminated and all outstanding and unexpired stock options and all shares of restricted stock outstanding under the terminated plans became equivalent awards of the Company under the 2019 Plan.

At June 30, 2025, the maximum number of shares authorized for issuance under the 2019 Plan was 3,400,000.

In addition, the 2019 Plan permits the Company to grant additional stock options and restricted share units. The Plan provides for the granting to eligible participants such incentive awards as the Board of Directors or a committee established by the Board, in its sole discretion, to administer the Plan. The Board has the power to determine the terms of the awards, including the exercise price, the number of shares subject to each award, the vesting and exercisability of the awards and the form of consideration payable upon exercise. Stock options expire no later thanten years from the date of the grant. The 2019 Plan provides for accelerated vesting if there is a change of control, as defined in the Plan. Restricted stock units generally vest over a period ofone tofive years.

Future levels of compensation cost recognized related to stock-based compensation awards may be impacted by new awards and/or modifications, repurchases and cancellations of existing awards. Under the terms of the 2019 Plan, vested options generally expire ninety days after the director or employee terminates their service affiliation with the Company.

In connection with the Merger, each of the 185,878 outstanding, unvested restricted stock units granted to the continuing directors, executives and employees under CALB’s Amended and Restated 2017 Equity Incentive Plan were converted into 295,512 unvested restricted stock units of the Company. Each such converted restricted stock unit award continues to be subject to the same terms and conditions as were applicable to the corresponding CALB restricted stock unit award immediately prior to the Merger. The weighted average remaining term on these assumed restricted stock units was 4.0 years, ranging fromtwo months to 5.0 years. All outstanding unvested CALB restricted stock units of 77,436 shares in aggregate that were held by employees who are not continuing directors, executives and employees were accelerated and became fully vested and converted automatically into the right to receive approximately 82,364 shares of the Company’s common stock after 25,635 of CALB shares were surrendered by certain executives and employees to pay for taxes at the effective time of the Merger.

For the three and six months ended June 30, 2025, total stock-based compensation cost related to stock options and restricted stock units was $1.5 million and $3.0 million, respectively. For the three and six months ended June 30, 2024, total stock-based compensation cost related to stock options and restricted stock units was $996 thousand and $1.9 million, respectively.

Stock Options

As of June 30, 2025, there was $14 thousand of total unrecognized compensation cost related to the outstanding stock options. There were 9,375 stock options exercised with the intrinsic value of $79 thousand during the three months ended June 30, 2025, andno stock options exercised during the three months ended June 30, 2024. There were $11 thousand related tax benefit for the disqualifying disposition of incentive stock options (“ISO”) exercised for the three months ended June 30, 2025. Related tax expense for non-qualified stock option exercised were approximately $6 thousand for the three months ended June 30, 2024.

There were 14,513 and 81,400 stock options exercised during the six months ended June 30, 2025 and 2024, respectively. The intrinsic value of stock options exercised was approximately $119 thousand and $558 thousand for the six months ended June 30, 2025 and 2024, respectively. There were $11 thousand related tax benefit for the disqualifying disposition of ISO exercised for the six months ended June 30, 2025. Related tax expense for non-qualified stock option exercised were approximately $32 thousand for the six months ended June 30, 2024.

The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model. There wereno options granted during the three and six months ended June 30, 2025 and 2024.

A summary of changes in outstanding stock options during the three and six months ended June 30, 2025 and 2024 are presented below:

Restricted Stock Units

A summary of the changes in outstanding unvested restricted stock units during the three and six months ended June 30, 2025 and 2024 is presented below:

As of June 30, 2025, the Company didnot have any outstanding unvested restricted stock units subject to various financial performance conditions.

As of June 30, 2025, there was $10.6 million of total unrecognized compensation expense related to the outstanding restricted stock units that will be recognized over the weighted-average period of 2.9 years. The total unrecognized compensation expense included $826 thousand related to the fair value of outstanding restricted stock units that was assumed from the Merger which will be recognized over the weighted-average vesting period of 3.2 years. The total grant date fair value of restricted stock units vested was $923 thousand and $4.1 million for the three and six months ended June 30, 2025, and $420 thousand and $2.2 million for the three and six months ended June 30, 2024. Related tax expenses were approximately zero and $5 thousand for the three and six months ended June 30, 2025, and approximately zero and $53 thousand for the three and six months ended June 30, 2024.

NOTE 14 -FAIR VALUE

The fair value of a financial instrument is the amount at which the asset or obligation could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale. Fair value estimates are made at a specific point in time based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the entire holdings of a particular financial instrument. Because no market value exists for a significant portion of the financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature, involve uncertainties and matters of judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

ASC Topic 820, Fair Value Measurements and Disclosures, establishes a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The guidance describes three levels of inputs that may be used to measure fair value:

Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date.

Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

Level 3: Significant unobservable inputs that reflect a Company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability.

Fair value of financial instruments

Fair value estimates are based on financial instruments both on and off the balance sheet without attempting to estimate the value of anticipated future business, and the value of assets and liabilities that are not considered financial instruments. Additionally, tax consequences related to the realization of the unrealized gains and losses can have a potential effect on fair value estimates and have not been considered in many of the estimates. The following methods and assumptions were used to estimate the fair value of significant financial instruments:

Cash and Due from Banks: The carrying amounts of cash and short-term instruments approximate fair values because of the liquidity of these instruments.

Federal Funds Sold and Interest-Bearing Balances: The carrying amount is assumed to be the fair value given the short-term nature of these deposits.

Debt Securities Held to Maturity and Available for Sale: The fair values of securities held to maturity and available for sale are determined by obtaining quoted prices on nationally recognized securities exchanges or matrix pricing, which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted prices for specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities.

Loans Held for Sale: The fair value of loans held-for-sale is based on commitments outstanding from investors as well as what secondary market investors are currently offering for portfolios with similar characteristics.

Loans Held for Investment, net: The fair value of loans, which is based on an exit price notion, is generally determined using an income based approach based on discounted cash flow analysis. This approach utilizes the contractual maturity of the loans and market indications of interest rates, prepayment speeds, defaults and credit risk in determining fair value. The fair value for PCD loans incorporated market-based loss rates used to estimate the expected life of loan credit losses. The noncredit discount resulting from the acquired PCD loans was allocated to each individual asset. If an individually evaluated loan has had a charge-off or if the fair value of the collateral is less than the recorded investment in the loan, we establish a specific reserve and report the loan as nonrecurring Level 3. Loans not requiring an allowance represent loans for which the fair value of the expected repayments or collateral exceed the recorded investments in such loans. For the fair value of collateral-dependent individually evaluated loans, an asset-based approach is applied to determine the estimated fair values of the underlying collateral based on recent real estate appraisals, less costs to sell. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. New appraisals are conducted in certain circumstances, including when there has been significant deterioration in the condition of the collateral, if the foreclosure process has begun, or if the existing valuation is deemed to be outdated. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value.

Restricted Stock Investments: Investments in FHLB and Federal Reserve stocks are recorded at cost and measured for impairment. Ownership of FHLB and Federal Reserve stocks are restricted to member banks and the securities do not have a readily determinable market value. Purchases and sales of these securities are at par value with the issuer. The fair value of investments in FHLB and Federal Reserve stock is equal to the carrying amount.

Other Equity Securities: The fair value of equity securities is based on quoted prices in active markets for identical assets to determine the fair value. If quoted prices are not available to determine fair value, the Company estimates the fair values by using independent pricing models, quoted prices of securities with similar characteristics, or discounted cash flows.

Other Real Estate Owned (“OREO”): Nonrecurring adjustments to certain commercial and residential real estate properties classified as OREO are measured at the lower of the carrying amount or fair value, less costs to sell. The fair value of OREO is generally based on recent real estate appraisals or broker opinions, obtained from independent third parties, which are frequently adjusted by management to reflect current conditions and estimated selling costs.

Accrued Interest Receivable: The fair value of accrued interest receivable approximates their carrying amounts.

Deposits: The fair values disclosed for demand deposits, including interest and non-interest demand accounts, savings, and certain types of money market accounts are by definition based on carrying value. Fair value for fixed-rate certificates of deposit is estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregate expected monthly maturities on time deposits. Early withdrawal of fixed-rate certificates of deposit is not expected to be significant.

Borrowings: The fair values of the Company’s overnight borrowings from the Federal Home Loan Bank approximates their carrying value as the advances were recently borrowed at market rate. The fair value of fixed-rated term borrowings is estimated using a discounted cash flow through the remaining maturity dates based on the current borrowing rates for similar types of borrowing arrangements. The fair values of subordinated debt are based on rates currently available to the Company for debt with similar terms and remaining maturities.

Accrued Interest Payable: The fair value of accrued interest payable approximates their carrying amounts.

Off-Balance Sheet Financial Instruments: The fair value of commitments to extend credit and standby letters of credit is estimated using the fees currently charged to enter into similar agreements. The fair value of these financial instruments is not material.

The estimated fair value hierarchy level and estimated fair value of financial instruments at June 30, 2025 and December 31, 2024, is summarized as follows:

Recurring fair value measurements

The following table provides the hierarchy and fair value for each major category of assets and liabilities measured at fair value on a recurring basis at the periods indicated:

Nonrecurring fair value measurements

The Company may also be required, from time to time, to measure certain other assets and liabilities on a nonrecurring basis in accordance with generally accepted accounting principles.

Collateral-dependent loans. For the valuation of the collateral-dependent loans, the Company relies primarily on third-party valuation information from certified appraisers and values are generally based upon recent appraisals of the underlying collateral, brokers’ opinions based upon recent sales of comparable properties, estimated equipment auction or liquidation values, income capitalization, or a combination of income capitalization and comparable sales. Depending on the type of underlying collateral, valuations may be adjusted by management for qualitative factors such as economic factors and estimated liquidation expenses. The range of these possible adjustments may vary. At June 30, 2025, the Company’s individual evaluated collateral-dependent loans were evaluated based on the estimated fair value of the underlying collateral from the Company’s internal reviews, including reviews of the most recent appraisals and the current sale market condition. There wereno partial charge-offs on certain individually evaluated loans based on recent real estate or property appraisals andno related specific reserves were recorded during the six months ended June 30, 2025.

Other real estate owned, net (“OREO”). Subsequent to foreclosure, it may be necessary to record nonrecurring fair value adjustments for declines in fair value of OREO. Fair value, when recorded, is determined based on appraisals by qualified licensed appraisers and adjusted for management’s estimates of costs to sell. Accordingly, values for OREO are classified as Level 3.

The following tables summarize the fair value of assets and liabilities measured at fair value on a nonrecurring basis as of June 30, 2025 and December 31, 2024. There wasno OREO as of June 30, 2025. OREO is presented net of an allowance of $614 thousand as of December 31, 2024. Only individually evaluated collateral-dependent loans with a related specific ACL or a partial charge off are included in the following table for purposes of fair value disclosures.
