Organization, Consolidation and Presentation of Financial Statements [Abstract]

Summary of Significant Accounting Policies

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates — The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. A material estimate that is particularly susceptible to significant change in the near term relates to the determination of the allowance for credit losses. Other significant estimates, which may be subject to change, include fair value determinations and disclosures, impairment of investments, goodwill, loans, as well as valuation of deferred tax assets.

Business Segments — We regularly assess our strategic plans, operations, reporting structures and financial information provided to the Chief Executive Officer, our chief operating decision maker (“CODM”), to identify our reportable segments. At December 31, 2025 and since September 30, 2018, we have operated as one reportable segment. Changes to our reportable segments are expected to be infrequent.

The factors considered in making this determination included the nature of products and services offered, geographic regions in which we operate, the applicable regulatory environment, and the materiality of discrete financial information reviewed by our CODM. Through our network of banking centers, we provide relationship-based banking products, services and solutions for small to mid-sized companies, real estate investors, non-profit organizations, professionals and other individuals. Our products include loans for commercial businesses, commercial real estate, multi-family, construction, land, dairy & livestock and agribusiness, consumer and government-guaranteed small business loans. We also provide business deposit products and treasury cash management services, as well as deposit products to the owners and employees of the businesses we serve. Our operations are throughout the state of California.

The Company's operating model is structured whereby banking divisions serve a similar base of primarily commercial clients utilizing a company-wide offering of similar products and services managed through similar processes and platforms, and therefore operates one line of business that is collectively reviewed by the CODM. The CODM regularly assesses performance of the aggregated single reporting segment and decides how to allocate resources based on net income calculated on the same basis as net income reported in the Company's consolidated statements of earnings and comprehensive income. The CODM is also regularly provided with expense information at a level consistent with that disclosed in the Company's consolidated statements of earnings and comprehensive income.

Cash and cash equivalents — Cash on hand, cash items in the process of collection, and amounts due from correspondent banks, the Federal Reserve Bank and interest-bearing balances due from depository institutions with initial terms of ninety days or less, are included in Cash and cash equivalents.

Investment Securities — Investments in debt securities that the Company has the positive intent and ability to hold to maturity are classified as HTM. Securities classified as trading are those securities that are bought and held principally for the purpose of selling them in the near term. All other debt and equity securities are classified as AFS. HTM securities are accounted for at cost and adjusted for amortization of premiums and accretion of discounts. Trading securities are accounted for at fair value with the unrealized gains and losses being included in current earnings. AFS securities are accounted for at fair value, with the net unrealized gains and losses, net of income tax effects, presented as a separate component of stockholders’ equity in accumulated other comprehensive loss, net. Realized gains and losses on sales of securities are recognized in earnings at the time of sale and are determined on a specific-identification basis is recorded on a trade date basis based on the amortized cost basis of the specific security and are included in noninterest income as net gain (loss) on sales of investment securities. Purchase premiums and discounts are recognized in interest income using the effective-yield method over the estimated terms of the securities. For mortgage-backed securities (“MBS”), the amortization or accretion is based on estimated average lives of the securities. The lives of these securities can fluctuate based on the amount of prepayments received on the underlying collateral of the securities.

The Bank is a member of the Federal Home Loan Bank (“FHLB”) and the Federal Reserve Bank of San Francisco (“FRB”) System.The Company’s investments in FHLB stock and FRB stock are carried at cost and periodically assessed for impairment. Both cash and stock dividends received on FHLB stock and FRB stock are reported as a component of total interest income in the Company's consolidated statements of earnings and comprehensive income.

In accordance with Accounting Standards Codification (“ASC”) 326, Financial Instruments — Credit Losses, AFS debt securities are measured at fair value and are subject to impairment testing. A security is impaired if the fair value of the security is less than its amortized cost basis. When an AFS debt security is considered impaired, the Company must determine if the decline in fair value has resulted from a credit-related loss or other factors and then, (1) recognize allowance for credit losses by a charge to earnings for the credit-related component (if any) of the decline in fair value, and (2) recognize in other comprehensive income (loss) non-credit related components of the fair value decline (if any). If the amount of the amortized cost basis expected to be recovered increases in a future period, the valuation allowance would be reduced, but not more than the amount of the current existing allowance for that security.

Loans and Lease Finance Receivables — Loans and lease finance receivables that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the principal balance outstanding, net of nonaccrual interest paid, deferred loan origination fees and costs, and purchase price discounts and premiums (amortized cost basis). Refer to Note 5 — Loans and Lease Finance Receivables and Allowance for Credit Losses.

In the ordinary course of business, the Company enters into commitments to extend credit to its customers. To the extent that such commitments are unfunded, the related unfunded amounts are not reflected in the accompanying consolidated financial statements.

The Company receives collateral to support loans, lease finance receivables, and commitments to extend credit for which collateral is deemed necessary. The most significant categories for which collateral is deemed necessary are real estate, principally commercial and industrial income-producing properties, Small Business Administration (“SBA”) loans, real estate mortgages, assets utilized in dairy & livestock and agribusiness, and various personal property assets utilized in commercial and industrial business governed by the Uniform Commercial Code.

Nonrefundable fees and direct costs associated with the origination or purchase of loans are deferred and netted against outstanding loan balances. The deferred net loan fees and costs and purchase price discounts and premiums are accreted or amortized to interest income over the loan term using the effective-yield method.

Nonaccrual, Past Due, Charge-Offs and Recoveries — Interest on loans and lease finance receivables, is credited to income based on the principal amounts of such loans or receivables outstanding. Loans are considered delinquent when principal or interest payments are past due 30 days or more and generally remain on accrual status between 30 and 89 days past due. Loans on which the accrual of interest has been discontinued are designated as nonaccrual loans. In general, interest shall not accrue on any loan for which payment in full of principal and interest is not expected, or when the loan becomes 90 days past due, unless the loan is both well secured and in the process of collection. Factors considered in determining that the full collection of principal and interest is no longer probable include cash flow and liquidity of the borrower or property, the financial position of the guarantors and their willingness to support the loan as well as other factors, and this determination involves significant judgment. When an asset is placed on nonaccrual status, previously accrued but unpaid interest is reversed against income and the accrual of interest income is discontinued. Subsequent collections of cash are applied as reductions to the principal balance unless the loan is returned to accrual status. Interest is not recognized using a cash-basis method. Nonaccrual loans may be restored to accrual status when principal and interest become current and when the borrower is able to demonstrate payment performance for a sustained period, typically for six months. A nonaccrual loan may return to accrual status sooner based on other significant events or mitigating circumstances. Interest income is not recognized on loans and lease finance receivables when collection of interest is deemed by management to be doubtful. Charge-offs are recognized in the period an obligation becomes uncollectible. When determining the amount of the charge-off, management considers all components of the loan’s amortized cost basis, excluding accrued interest receivable (as disclosed herein); however, the non-principal portion of charge-offs have been determined to be immaterial. This policy is consistently applied to all types of loans and lease finance receivables.

Charge-offs of unsecured consumer loans are recorded when the loan reaches 120 days past due or sooner as circumstances indicate.

Purchased Loans — When loans are purchased or acquired, an assessment is first performed to determine if such loans have experienced more than insignificant deterioration in credit quality since their origination and thus should be classified as purchased credit deteriorated (“PCD”) loans or otherwise classified as non-PCD loans. All purchased loans are initially measured and recorded at their fair value on the acquisition date. A component of the initial fair value measurement is an estimate of the credit losses over the life of the purchased loans. Any resulting discount or premium recorded on acquired loans is accreted or amortized into interest income over the remaining life of the loans using the interest method. Additionally, upon the purchase or acquisition of non-PCD loans, the Company measures and records an allowance for credit losses (“ACL”) based on the Company’s ACL methodology.

ASC 326 requires PCD assets to be recorded at their purchase price plus an allowance for credit losses estimated at the time of acquisition. Acquired PCD loans are initially recorded at fair value, with the resulting non-credit discount or premium being amortized or accreted into interest income using the interest method. The acquisition-date ACL for PCD loans will be allocated to the individual PCD loans (assuming it was originally determined on a collective basis). The sum of the purchase price of the loan (the acquisition date fair value for a loan acquired in a business combination) and the ACL becomes the loan’s new amortized cost basis. Subsequent to an acquisition, the ACL for PCD loans will generally follow the same estimation, provision and charge-off process as non-PCD acquired and originated loans. Additionally, the identification of modified loans to borrowers experiencing financial difficulty for acquired loans (PCD and non-PCD) will be consistent with the identification for originated loans.

Modifications of Loans to Borrowers Experiencing Financial Difficulty

The Company adopted Accounting Standards Update 2022-02, Financial Instruments - Credit Losses (Topic 326) Troubled Debt Restructurings and Vintage Disclosures (“ASU 2022-02”) effective January 1, 2023. The amendments in ASU 2022-02 eliminated the recognition and measurement of troubled debt restructurings and enhanced disclosures for loan modifications to borrowers experiencing financial difficulty.

A debtor is considered to be experiencing financial difficulty when there is significant doubt about the debtor’s ability to make required payments on the debt or to get equivalent financing from another creditor at a market rate for similar debt. The Company may modify the contractual terms of loans and leases to a borrower experiencing financial difficulties as a way to mitigate loss, proactively work with borrowers in financial difficulty, or to comply with regulations regarding the treatment of certain bankruptcy filing and discharge situations. Modifications to borrowers in financial difficulty may include term extensions, interest rate reductions, principal or interest forgiveness, an other-than-insignificant payment delay, or any combination of these. Loans are assessed to determine whether the modification constitutes a new loan or a continuation of the existing loan. The Company closely monitors the performance of loans and leases that are modified for borrowers experiencing financial difficulty to understand the effectiveness of its modification efforts. Loans and leases with modifications to borrowers experiencing financial difficulty are subject to policies governing accrual/nonaccrual evaluation consistent with all other loans of the same product types. As such, modifications to borrowers may include loans remaining on nonaccrual, moving to nonaccrual, or continuing on accrual status, depending on the individual facts and circumstances.

A loan that has been placed on nonaccrual status that is subsequently restructured will remain on nonaccrual status until the borrower is able to demonstrate repayment performance in compliance with the restructured terms for a sustained period of time, generally for a minimum of six months. A restructured loan may return to accrual status sooner based on other significant events or circumstances.

Provision and Allowance for Credit Losses — In accordance with ASC 326, our allowance for credit losses is based upon lifetime loss rate models developed from an estimation framework that uses historical lifetime loss experiences to derive loss rates at a collective pool level. This current expected credit losses (“CECL”) model, applies to: (1) financial assets subject to credit losses and measured at amortized cost, and (2) certain off balance sheet credit exposures. This includes, but is not limited to, loans, HTM securities, loan commitments, and financial guarantees. AFS debt securities are measured at fair value and are subject to impairment testing. This ASU for AFS debt securities requires an allowance for credit impairment instead of a direct write-down, which allows for reversal of credit impairments in future periods based on improvements in credit. When an AFS debt security is considered impaired, and the Company determines that the decline in fair value has resulted from a credit-related loss (as described previously under Investment Securities), then an allowance for credit losses will be recognized by a charge to earnings for the credit-related component of the decline in fair value. As a result, we will recognize improvements to estimated credit losses immediately in earnings. As a policy election, we exclude the accrued interest receivable balance from the amortized cost basis of financing receivables and HTM securities, as well as AFS securities, and disclose total accrued interest receivable separately on the consolidated balance sheet. If accrued interest is not received, it is reversed against interest income.

We monitor credit quality by evaluating various risk attributes and utilize such information in our evaluation of the appropriateness of the allowance for credit losses. An important element of our approach to credit risk management is our loan risk rating system (Pass, Special Mention, Substandard, Doubtful and Loss). Loan risk ratings are updated as facts related to the loan or borrower become available. In addition, all term loans in excess of $1.0 million are subject to an annual internal credit review process where all factors underlying the loan, borrower and guarantors are subject to review which may result in changes to the loan’s risk rating.

Our methodology for assessing the appropriateness of the allowance is conducted on a regular basis and considers the Bank’s overall loan portfolio. Refer to Note 5 — Loans and Lease Finance Receivables and Allowance for Credit Losses, Credit Quality Indicators.

Reserve for Unfunded Loan Commitments — The reserve for off-balance sheet credit exposure relates to commitments to extend credit, letters of credit and undisbursed funds on lines of credit. The Company evaluates credit risk associated with the off-balance sheet loan commitments in the same manner as it evaluates credit risk associated with the loan and lease portfolio. The reserve is calculated on the expected portion of the commitment to be funded over its life and the life of the commitment loss expectation, utilizing the same three collective pool methodologies described for the Allowance for Credit Losses. We include the reserve for unfunded loan commitments in other liabilities and the related provision in other noninterest expense.

Other Real Estate Owned — Other real estate owned (“OREO”) represents real estate acquired through foreclosure in lieu of repayment of commercial and real estate loans and is initially recorded at fair value, less estimated costs to sell (establishing a new cost basis). Loan balances in excess of fair value of the real estate acquired at the date of acquisition are charged against the allowance for credit losses. Any subsequent operating expenses or income, reduction in estimated values, and gains or losses on disposition of such properties are charged to current operations. Gain recognition upon disposition of a property is dependent on the sale having met certain criteria relating to the buyer’s initial investment in the property sold.

Premises and Equipment — Premises and equipment are stated at cost, less accumulated depreciation, which is provided for in amounts sufficient to relate the cost of depreciable assets to operations over the estimated service lives of the respective asset and are computed on a straight-line basis. The ranges of useful lives of the principal classes of assets are as follows:


Bank premises	15 - 39 years
Leasehold improvements	Shorter of estimated economic lives of 15 years or term of the lease.
Computer equipment	3 - 7 years
Furniture, fixtures and equipment	5 - 10 years

Long-lived assets are reviewed periodically for impairment when events or changes in circumstances indicate that the carrying amount may not be recoverable. The existence of impairment is based on undiscounted cash flows. To the extent impairment exists, the impairment is calculated as the difference in fair value of assets and their carrying value. The impairment loss, if any, would be recorded in noninterest expense. Net gains or net losses on dispositions of premises and equipment are recorded in noninterest income.

Long-lived assets classified as held-for-sale are measured at the lower of its carrying amount or fair value less cost to sell. Assets-held-for sale include long-lived assets transferred from our “held-and-used” portfolio in the period in which the following criteria are met:

•

Management, having the authority to approve the action, commits to a plan to sell the asset;

•

The asset is available for immediate sale, an active program to locate a buyer and other actions required to complete the plan to sell the asset have been initiated;

•

The sale of the asset is probable, and transfer of the asset is expected to qualify for recognition as a completed sale, within one year;

•

The asset is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and

•

Actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn.

Goodwill and Intangible Assets — Goodwill resulting from business combinations prior to January 1, 2009, represents the excess of the purchase price over the fair value of the net assets of the businesses acquired. Goodwill resulting from business combinations after January 1, 2009, is generally determined as the excess of the fair value of the consideration transferred, plus the fair value of any non-controlling interest in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but are tested for impairment at least annually, or more frequently, if events and circumstances exist that indicate that a goodwill impairment test should be performed.

Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. Goodwill is the only intangible asset with an indefinite life on our balance sheets. Based on the Company’s annual impairment test, there was no recorded impairment as of December 31, 2025.

Other intangible assets consist of core deposit intangible assets arising from business combinations and are amortized using an accelerated method over their estimated useful lives.

Use of Fair Value — We use fair value measurements to record fair value adjustments to certain financial instruments and to determine fair value disclosures. Investment securities available-for-sale and interest-rate swaps are financial instruments recorded at fair value on a recurring basis. Additionally, from time to time, we may be required to record at fair value other assets on a non-recurring basis, such as individually evaluated loans and OREO. These non-recurring fair value adjustments typically involve application of lower-of-cost-or-market accounting or write-downs of individual assets. Further, we include in Note 17 — Fair Value Information of the consolidated financial statements information about the extent to which fair value is used to measure assets and liabilities, the valuation methodologies used and its impact to earnings. Additionally, for financial instruments not recorded at fair value we disclose the estimate of their fair value. Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully described in a separate note.

Bank Owned Life Insurance — The Company invests in BOLI that involves the purchasing of life insurance by the Company on a select group of employees. The Company is the owner and primary beneficiary of these policies. BOLI is recorded as an asset at the cash surrender value. Changes in the cash value of these policies, as well as insurance proceeds received, are recorded in other noninterest income and are not subject to income tax for as long as they are held for the life of the covered employee.

Qualified Affordable Housing Partnerships and Tax Credit Partnerships — The Bank invests in qualified affordable housing partnerships and accounts for these investments using the proportional amortization method. Under the proportional amortization method, the Bank amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received, and recognizes the amortization as a component of income tax expense. The Bank also invests in various tax credit partnerships pursuant to Sections 42 and 48 of the Internal Revenue Code of 1986. The Bank acts as a limited partner in these investments and does not exercise control over the financial or operating policies of the partnerships and as such, is not considered the primary beneficiary of the partnership. Upon entering into new solar tax equity investments in the second quarter of 2023, the Company elected to account for tax credit partnerships using the proportional amortization method on a prospective basis.

Income Taxes — Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Future realization of deferred tax assets ultimately depends on the existence of sufficient taxable income of the appropriate character (for example, ordinary income or capital gain) within the carryback or carryforward periods available under the tax law. Based on historical and future expected taxable earnings, the Company considers the future realization of these deferred tax assets more likely than not. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized.

The tax effects from an uncertain tax position are recognized in the financial statements only if, based on its merits, the position is more likely than not to be sustained on audit by the taxing authorities. The Company recognizes interest and/or penalties related to income tax matters in income tax expense. Refer to Note 9 — Income Taxes for additional information.

Operating Leases — At December 31, 2025, the Company only had operating leases for our leased facilities, which are used primarily for the banking operations of the Company. All leases in the current portfolio have been classified as operating leases, although this may change in the future. Operating leases with a term of more than one year are included in operating lease right-of-use (“ROU”) assets and operating lease liabilities on the Company’s consolidated balance sheets. The Company made a policy election to apply the short-term lease exemption to any operating leases with an original term of less than 12 months, therefore no ROU asset or lease liability is recorded for these operating leases. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the obligation to make lease payments arising from the lease. The Company determines if an arrangement is a lease at inception by assessing whether there is an identified asset and whether the contract conveys the right to control the use of the identified asset for a period of time in exchange for consideration.

Operating lease ROU assets and lease liabilities are included in other assets and other liabilities, respectively, on the Company’s consolidated balance sheet. The Company uses its incremental borrowing rate, factoring in the lease term, to determine the lease liability, which is measured at the present value of future lease payments. The ROU assets, at adoption of this ASU, were initially recorded at the amount of the lease liability plus any prepaid rent and initial direct costs, less any lease incentives and accrued rent. The lease terms include periods covered by options to extend or terminate the lease depending on whether the Company is reasonably certain to exercise such options. Refer to Note 21 — Leases for more information.

Earnings per Common Share — The Company calculates earnings per common share (“EPS”) using the two-class method. Under the two-class method, earnings available to common stockholders for the period are allocated between common stockholders and participating securities according to dividends declared and participation rights in undistributed earnings. All outstanding unvested share-based payment awards that contain rights to non-forfeitable dividends are considered participating securities. The Company has granted restricted shares under the 2008 and 2018 Equity Incentive Plans that qualify as participating securities. Restricted shares issued under these plans are entitled to dividends at the same rate as common stockholders. A reconciliation of the numerator and the denominator used in the computation of basic and diluted earnings per common share is included in Note 14 — Earnings Per Share Reconciliation of these consolidated financial statements.

Stock-Based Compensation — The Company issues stock-based compensation instruments consisting of incentive stock options (“ISOs”), time-based restricted stock awards (“RSAs”), restricted stock units (“RSUs”) and performance-based restricted stock units (“PRSUs”). Compensation expense related to ISOs and RSAs is based on the fair value of the underlying stock on the award date and is recognized over the required service period using the straight-line method. Forfeitures of stock-based awards are recognized when they occur.

The fair value of each ISO grant is estimated as of the grant date using the Black-Scholes option-pricing model. Management assumptions used at the time of grant impact the fair value of the option calculated under the Black-Scholes option-pricing model, and ultimately, the expense that will be recognized over the life of the option.

The grant date fair value of RSA, RSU and PRSU awards is the market price of the Company's common stock at the date of grant. Compensation expense related to PRSUs is amortized over the vesting period using the straight-line method unless it is determined that: (1) attainment of the financial metrics is less than probable, in which case a portion of the amortization is suspended, or (2) attainment of the financial metrics is improbable, in which case a portion of the previously recognized amortization is reversed and also suspended. PRSU expense may vary during the performance period based upon changes in management's estimate of the number of shares that may ultimately vest.

Unexercised ISOs do not participate with common stock in any dividends declared and paid. Unvested RSAs participate with common stock in any dividends declared and paid. Unvested PRSUs participate with common stock in any dividends declared, but are only paid on the shares which ultimately vest, if any, at the end of the performance period. At the time of vesting, the vested shares are entitled to receive cumulative dividends declared and paid during the performance period.

Additional information is included in Note 15 — Stock-Based Compensation Plans of the consolidated financial statements included herein.

Derivative Financial Instruments — All derivative instruments, including certain derivative instruments embedded in other contracts, are recognized on the consolidated balance sheets at fair value. On the date the derivative contract is entered into, the Company designates the derivative as a fair value hedge (i.e., a hedge of the fair value of a recognized asset or liability), a cash flow hedge (i.e., a hedge of the variability of cash flows to be received or paid related to a recognized asset or liability), or a free-standing derivative instrument. For derivatives designated as fair value hedges, changes in the fair value of the derivative and the hedged item related to the hedged risk are recognized in earnings. All changes in fair value for cash flow hedges, are recorded in “Other Comprehensive Income,” net of deferred taxes, including any ineffectiveness as long as the hedge remains highly effective.

We assess hedge effectiveness under ASC 815, Derivatives and Hedging, on a quarterly basis to ensure all hedges remain highly effective and hedge accounting under ASC 815 can be applied. In conjunction with the assessment of effectiveness, we assess the hedged item to ensure it is expected to be outstanding at the hedged item’s assumed maturity date and the portfolio layer method of accounting under ASC 815 can be applied. The portfolio layer method allows multiple hedged layers of a single closed portfolio. Fair value basis adjustments in an existing portfolio layer method hedge are maintained at the closed portfolio level (Balance Sheet line item level) and are therefore not allocated to individual assets.

Statement of Cash Flows — Cash and cash equivalents, as reported in the statements of cash flows, include cash and due from banks, interest-bearing balances due from depository institutions and federal funds sold with original maturities of three months or less. Cash flows from loans and deposits are reported net.

Other Contingencies — In the ordinary course of business, the Company becomes involved in litigation. Based upon the Company’s internal records and discussions with legal counsel, the Company records accruals as appropriate, for estimates of the probable outcome of all cases brought against the Company. Except as discussed in Note 12 — Commitments and Contingencies at December 31, 2025, the Company does not have any material litigation accruals and is not aware of any material pending legal action or complaints asserted against the Company.

Adoption of New Accounting Standards

In December 2023, the FASB issued Accounting Standard Update (“ASU”) 2023-09, Income Taxes (Topic 740) - Improvements to Income Tax Disclosures. This ASU enhances annual income tax disclosures to address investor requests for more detailed information about tax risks and improved transparency of income tax disclosures. The two primary enhancements disaggregate existing income tax disclosures related to the effective tax rate reconciliation and information on income taxes paid disaggregated by jurisdiction. The Company adopted this ASU effective January 1, 2025 with refined disclosure included in this Form 10-K. See Note 9 Income Taxes below. As the amendments in this update relate entirely to disclosure requirements, adoption of this guidance did not have an impact on the Company's financial position or results of operations.

Earnings Per Share Reconciliation

14. EARNINGS PER SHARE RECONCILIATION

Basic earnings per common share are computed by dividing income allocated to common stockholders by the weighted-average number of common shares outstanding during each period. The computation of diluted earnings per common share considers the number of shares issuable upon the assumed exercise of outstanding common stock options. Antidilutive common shares are not included in the calculation of diluted earnings per common share. For the years ended December 31, 2025, 2024 and 2023, shares deemed to be antidilutive, and thus excluded from the computation of earnings per common share were 643,000, 963,000 and 1,044,000, respectively.

The table below shows earnings per common share and diluted earnings per common share, and reconciles the numerator and denominator of both earnings per common share calculations.

Standard	Description	Adoption Timing	Impact on Financial Statements
ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses	In November, 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40 Disaggregation of Income Statement Expenses. This ASU requires disaggregated disclosure of income statement expenses for public business entities. This ASU does not change the expense captions an entity presents on the face of the income statement; rather, it requires disaggregation of certain expense captions into specified categories in disclosures in tabular format within the footnotes to the financial statements. The prescribed categories include employee compensation, depreciation, and intangible asset amortization. This ASU is effective for annual reporting periods beginning after December 15, 2026, and interim periods within fiscal years beginning in 2028. This ASU is to be applied on a prospective basis, though early adoption and retrospective application are permitted.	December 31, 2027	The adoption of this ASU is not expected to have a material impact on our consolidated financial statements.

ASU 2025-01, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date	In January 2025, the FASB issued ASU 2025-01, which amends the effective date of ASU 2024-03 to clarify that all public business entities are required to adopt the guidance in annual periods after December 15, 2026, and interim periods in fiscal years beginning after December 15, 2027.	See ASU 2024-03

ASU 2025-06, Intangibles - Goodwill and Other Internal-Use Software (subtopic 350-40)	In September 2025, the FASB issued ASU 2025-06, which provides targeted improvements to the accounting for internal-use software, including revising the cost capitalization threshold. This ASU is effective for all entities for annual and interim periods in fiscal years beginning after December 15, 2027. Early adoption is permitted .	December 31, 2027	The adoption of this ASU is not expected to have a material impact on our consolidated financial statements.

ASU 2025-07, Derivatives and Hedging (Topic 815) and Revenue from Contracts with Customers (Topic 606)	In September 2025, the FASB issued ASU 2025-07, which establishes accounting requirements for contracts that meet the characteristics-based definition of a derivative and are not otherwise excluded from the Topic's scope. This ASU is effective for all entities for annual and interim periods in fiscal years beginning after December 15, 2026. Early adoption is permitted.	December 31, 2027	The adoption of this ASU is not expected to have a material impact on our consolidated financial statements.


Standard	Description	Adoption Timing	Impact on Financial Statements
ASU 2025-08, Financial Instruments — Credit Losses (Topic 326): Purchased Loans	In November 2025, the FASB issued ASU 2025-09, which expands the use of the gross-up approach in Accounting Standards Codification (ASC) 326, Credit Losses, to all “purchased seasoned loans.” The ASU defines purchased seasoned loans as loans that are not purchased credit deteriorated (“PCD”) financial assets. All non-PCD loans (excluding credit cards) that are acquired in a business combination are deemed seasoned. Other non-PCD loans (excluding credit cards) are seasoned if they were purchased at least 90 days after origination and the acquirer was not involved in the origination of the loans. This ASU is effective for all entities for annual and interim periods in fiscal years beginning after December 15, 2026. Early adoption is permitted in an interim or annual reporting period in which financial statements have not yet been issued.	June 30, 2026	The Company expects to early adopt ASU 2025‑08 in 2026. The adoption of this standard is expected to affect the accounting for the pending merger with Heritage and will result in corresponding impacts to the Company’s consolidated financial statements. The Company is currently evaluating the full effect of the new guidance.

ASU 2025-09, Derivatives and Hedging (Topic 815): Hedge Accounting Improvements	In November 2025, the FASB issued ASU 2025-09, which amends certain aspects of hedge accounting guidance to better align with an entitiy's risk management activities and reflect those strategies in the financial statements. This ASU is effective for annual and interim periods in fiscal years beginning after December 15, 2026. Early adoption is permitted.	December 31, 2027	The adoption of this ASU is not expected to have a material impact on our consolidated financial statements.

ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements	In December 2025, the FASB issued ASU 2025-11, which clarifies interim disclosure requirements and creates a comprehensive list of interim disclosures required under U.S. GAAP and incorporates a disclosure principle that requires disclosures at interim periods when an event or change that has a material effect on an entity has occurred since the previous year end. This ASU is effective for interim reporting periods within annual reporting periods beginning after 15 December 2027. Early adoption is permitted.	March 31, 2028	The adoption of this ASU is not expected to have a material impact on our consolidated financial statements.

Lease expense for operating leases is recognized on a straight-line basis over the term of the lease and is reflected in the consolidated statement of earnings. Right-of-use (“ROU”) assets and lease liabilities are included in other assets and other liabilities, respectively, on the Company’s consolidated balance sheet.

While the Company has, as a lessor, certain equipment finance leases, such leases are not material to the Company’s consolidated financial statements.

The tables below present the components of lease costs and supplemental information related to leases as of and for the periods presented.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

18. DERIVATIVE FINANCIAL INSTRUMENTS

Derivatives Not Designated as Hedging Instruments

The Bank is exposed to certain risks relating to its ongoing business operations and utilizes interest rate swap agreements (“swaps”) as part of its asset/liability management strategy to help manage its interest rate risk position. As of December 31, 2025 the Bank has entered into 103 interest-rate swap agreements with customers with a notional amount totaling $318.4 million. The Bank then entered into identical offsetting swaps with counterparties. The swap agreements are not designated as hedging instruments. The purpose of entering into offsetting derivatives not designated as a hedging instrument is to provide the Bank a variable-rate loan receivable and to provide the customer the financial effects of a fixed-rate loan without creating significant volatility in the Bank’s earnings.

The structure of the swaps is as follows. The Bank enters into an interest rate swap with its customers in which the Bank pays the customer a variable rate and the customer pays the Bank a fixed rate, thereby allowing customers to in effect convert variable rate loans to fixed rate loans. At the same time, the Bank enters into a swap with a counterparty bank in which the Bank pays the counterparty a fixed rate and the counterparty in return pays the Bank a variable rate. The net effect of the transaction allows the Bank to receive interest on the loan from the customer at a variable rate based on Secured Overnight Financing Rate (“SOFR”) plus a spread. The changes in the fair value of the swaps primarily offset each other and therefore should not have a significant impact on the Company’s results of operations, although the Company does incur credit and counterparty risk with respect to performance on the swap agreements by the Bank’s customer and counterparty, respectively. These instruments contain language outlining collateral pledging requirements for each counterparty, whereby collateral must be posted if market value exceeds certain agreed upon threshold limits. Cash or securities are pledged as collateral. Our interest rate swap derivatives are subject to a master netting arrangement with our counterparties. None of our derivative assets and liabilities are offset in the Company’s condensed consolidated balance sheet.

We believe our risk of loss associated with our counterparty borrowers related to interest rate swaps is mitigated as the loans with swaps are underwritten to take into account potential additional exposure, although there can be no assurances in this regard since the performance of our swaps is subject to market and counterparty risk.

Derivatives Designated as Hedging Instruments

Fair Value Hedges

To manage interest rate risk on our AFS securities portfolio, we have entered into pay-fixed, receive-floating interest rate swap contracts to hedge against exposure to changes in the fair value of such securities resulting from changes in interest rates. We designate these interest rate swap contracts as fair value hedges that qualify for hedge accounting under ASC 815, Derivatives and Hedging. We elected to account for the fair value hedges using the portfolio layer method in accordance with ASU 2022-01. We record the interest rate swaps in the line items of “accrued interest receivable”, “other assets” and “other liabilities” on our consolidated balance sheet. For qualifying fair value hedges, both the changes in the fair value of the derivative and the portion of the fair value adjustments associated with the portfolio layer attributable to the hedged risk are recognized into earnings as they occur. Derivative amounts impacting earnings are recognized consistent with the classification of the hedged item in the line item "investment securities available for sale" as part of interest income, a component of consolidated net income.

In June 2023, fair value hedging transactions were executed in which $1 billion notional pay-fixed interest rate swaps were consummated with maturities ranging from four to five years, wherein the Company pays a weighted average fixed rate of approximately 3.8% and receives interest based on daily SOFR. In December 2024, we terminated one of these swaps which had a notional value of $300 million, a maturity date of June 2027 and a fixed rate of 3.95%. In May 2025, the remaining $700 million notional pay-fixed interest rate swaps, with a weighted average fixed rate of approximately 3.7%, that were scheduled to mature in June of 2028 were terminated and replaced with new pay-fixed interest rate swaps with maturity dates in May of 2029, 2030 and 2031, and a weighted pay-fixed rate of 3.68%. The new $700 million of fair value hedges have approximately equal nominal values maturing each of the three years and had a fair value which totaled $8.7 million and was reflected as a liability at December 31, 2025.

Cash Flow Hedges

To manage our interest rate risk associated with brokered CDs, FHLB advances or other fixed rate advances for specified periods, the Company enters into interest rate derivative contracts that are designated as qualifying cash flow hedges to hedge the exposure to variability in expected future cash flows attributable to changes in contractually specified interest rates. During the first quarter of 2024, $300 million of 3-month term brokered CDs were issued and cash flow hedging transactions were also executed in which $300 million notional pay-fixed interest rate swaps were consummated with maturities of three years, wherein the Company pays a weighted average fixed rate of approximately 4.2% and receives daily SOFR. The $300 million of brokered CDs were renewed every three months and as of December 31, 2025, the cash flow hedges have remaining maturities of approximately 15 months.

To qualify for hedge accounting, a formal assessment is prepared to determine whether the hedging relationship, both at inception and on an ongoing basis, is expected to be highly effective in achieving offsetting cash flows attributable to the hedged risk during the term of the hedge if a cash flow hedge. At inception a statistical regression analysis is prepared to determine hedge effectiveness. At each reporting period thereafter, a statistical regression or qualitative analysis is performed to determine hedge effectiveness. If it is determined that hedge effectiveness has not been or will not continue to be highly effective, then hedge accounting ceases and any gain or loss in AOCI is recognized in earnings immediately. The cash flow hedges are recorded at fair value in other assets and other liabilities on the consolidated balance sheets with changes in fair value recorded in AOCI, net of tax. All related cash flows are reported in the operating activities section of the consolidated statement of cash flows. Amounts recorded to AOCI are reclassified into earnings in the same period in which the hedged asset or liability affects earnings and are presented in the same income statement line item as the earnings effect of the hedged asset or liability.

Employee Benefit Plans

13. EMPLOYEE BENEFIT PLANS

Deferred Compensation Plans

As of December 31, 2025 the Company had various deferred compensation plans, including a deferred compensation plan for a former President and Chief Executive Officer,as well as severance arrangements it assumed through the acquisition of other banks in prior years. We also offer a non-qualified deferred compensation plan for our executives and key members of management in order to assist us in attracting and retaining these individuals. Participants in the plan may elect to defer a portion of their annual salary and/or short-term incentive payouts into deferral accounts to provide a means by which they may elect to defer receipt of compensation in order to provide retirement benefits. The plan is intended to be unfunded and allows us to make discretionary contributions on behalf of a participant. No discretionary payments were made by the Company during the years ended December 31, 2025, 2024 and 2023. The Bank, however, does fund the cost of these plans through the purchase of bank owned life insurance policies, which are reflected as assets on the Company’s consolidated balance sheets. At December 31, 2025 and 2024, the total deferred compensation liability was $22.3 million and $22.9 million, respectively. Total expense for these deferred compensation agreements was $1.5 million for the year ended December 31, 2025, and was $1.9 million and $1.2 million for the years ended December 31, 2024 and 2023, respectively.

401(k) and Profit Sharing Plan

The Bank sponsors a 401(k) and profit-sharing plan for the benefit of its employees. Employees are eligible to participate in the plan immediately upon hire. Employees may make contributions to the plan under the plan’s 401(k) component. The Bank contributes 3%, non-matching, to the plan to comply with ERISA’s safe harbor provisions. The Bank may make additional contributions under the plan’s profit-sharing component, subject to certain limitations. The profit-sharing contribution made for 2025 was 2%, compared to 1% for 2024 and 2% for 2023. The Bank’s total contributions are determined by the Board of Directors and amounted to approximately $5.1 million for 2025, $4.0 million for 2024, and $4.8 million for 2023.

Credit Quality Indicators

We monitor credit quality by evaluating various risk attributes and utilize such information in our evaluation of the appropriateness of the allowance for credit losses. Internal credit risk ratings, within our loan risk rating system, are the credit quality indicators that we most closely monitor.

An important element of our approach to credit risk management is our loan risk rating system. The originating officer assigns each loan an initial risk rating, which is reviewed and confirmed or changed, as appropriate, by credit management. Approvals are made based upon the amount of inherent credit risk specific to the transaction and are reviewed for appropriateness by senior line and credit management personnel. Credits are monitored by line and credit management personnel for deterioration or improvement in a borrower’s financial condition, which would impact the ability of the borrower to perform under the contract. Risk ratings are adjusted as necessary.

Loans are risk rated into the following categories: Pass, Special Mention, Substandard, Doubtful and Loss. Each of these groups is assessed for the proper amount to be used in determining the adequacy of our allowance for losses. These categories can be described as follows:

Pass — These loans, including loans on the Bank’s internal watch list, range from minimal credit risk to lower than average, but still acceptable, credit risk. Watch list loans usually require more than normal management attention. Loans on the watch list may involve borrowers with adverse financial trends, higher debt/equity ratios, or weaker liquidity positions, but not to the degree of being considered a defined weakness or problem loan where risk of loss may be apparent.

Special Mention — Loans assigned to this category have potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in the deterioration of the repayment prospects for the asset or the Company’s credit position at some future date. Special mention assets are not adversely classified and do not expose the Company to sufficient risk to warrant adverse classification.

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

Doubtful — Loans classified as doubtful have all the weaknesses inherent in those classified substandard with the added characteristic that the weaknesses make collection or the 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 loan has absolutely no recovery or salvage value, but rather that it is not practical or desirable to defer writing off this asset with insignificant value even though partial recovery may be affected in the future.

The following table summarizes loans by type and origination year, according to our internal risk ratings as of the dates presented.

The Company's allowance models calculate reserves over the average life of the loan, which includes the remaining time to maturity, adjusted for estimated prepayments applied as an adjustment to our commercial real estate and commercial and industrial loans. Our allowance for credit losses is based upon lifetime loss rate models developed from an estimation framework that uses historical lifetime loss experiences to derive loss rates at a collective pool level. We measure the expected credit losses on a collective (pooled) basis for those loans that share similar risk characteristics. We have three collective loan pools: Commercial Real Estate, Commercial and Industrial, and Consumer. A substantial portion of the ACL relates to loans within the Commercial Real Estate and Commercial and Industrial methodologies, each evaluated on a collective basis. Our ACL amounts are largely driven by portfolio characteristics, including loss history, internal risk grading, various risk attributes, and the economic outlook for certain macroeconomic variables. Risk attributes for commercial real estate loans include original loan to value ratios, origination year, loan seasoning, and macroeconomic variables that include GDP growth, commercial real estate price index and unemployment rate. Risk attributes for commercial and industrial loans include internal risk ratings, borrower industry sector, loan credit spreads and macroeconomic variables that include unemployment rate and BBB spread. The macroeconomic variables for Consumer include unemployment rate and GDP. The Commercial Real Estate methodology is applied over commercial real estate loans, a portion of construction loans, and a portion of SBA loans. The Commercial and Industrial methodology is applied over a substantial portion of the Company’s commercial and industrial loans, all dairy & livestock and agribusiness loans, municipal lease receivables, as well as the remaining portion of SBA loans (excluding PPP loans). The Consumer methodology is applied to SFR mortgage loans, consumer loans, as well as the remaining construction loans. In addition to determining the quantitative life of loan loss rate to be applied against the amortized cost basis of the portfolio segments, management reviews current conditions and forecasts to determine whether adjustments are needed to ensure that the life of loan loss rates reflect both the current state of the portfolio, and expectations for macroeconomic changes. The Company’s ACL estimate incorporates a reasonable and supportable forecast of various macroeconomic variables over the remaining average life of our loans. This forecast incorporates an assumption that each macroeconomic variable will revert to a long-term expectation, starting in years two through three, of the reasonable and supportable forecast period, with the reversion largely completed within the first five years of the forecast. The economic forecast is based on probability weighted scenarios to address macroeconomic uncertainty. Our methodology for assessing the appropriateness of the allowance is reviewed on a regular basis and considers overall risks in the Bank’s loan portfolio. Refer to Note 3 – Summary of Significant Accounting Policies contained herein for a more detailed discussion concerning the allowance for credit losses.

The ACL totaled $77.2 million as of December 31, 2025, compared to $80.1 million as of December 31, 2024. The $2.9 million decrease is comprised of a $3.5 million recapture of credit losses and $539,000 in net recoveries. At December 31, 2025, the ACL as a percentage of total loans and leases, at amortized cost was 0.89% of total loans. This compares to 0.94% at December 31, 2024. Our economic forecast continues to be a blend of multiple forecasts produced by Moody’s. These U.S. economic forecasts include a baseline forecast, as well as upside and downside forecasts. The baseline forecast continues to represent the largest weighting in our multi-weighted forecast scenario, with both upside and downside risks weighted among multiple forecasts. The resulting economic forecast reflects slower GDP growth of less than 2% for 2026 though 2028. Commercial Real Estate values are forecasted to continue their decline in 2026, with values starting grow in 2027 and valuations continuing to grow in 2028. Unemployment is forecasted to exceed 5% from mid 2026 until 2028.

Management believes that the ACL was appropriate at December 31, 2025 and 2024. Due to inflationary pressures, changing interest rates, lower commercial real estate values, international tariffs, and geopolitical events, no assurance can be given that economic conditions that adversely affect the Company’s service areas or other circumstances will not result in increased provisions for credit losses in the future.

Past Due and Nonperforming Loans

We seek to manage asset quality and control credit risk through diversification of the loan portfolio and the application of policies designed to promote sound underwriting and loan monitoring practices. The Bank’s Credit Management Division is responsible for monitoring asset quality, establishing credit policies and procedures and enforcing the consistent application of these policies and procedures across the Bank. Reviews of nonperforming, past due loans and larger credits, designed to identify potential charges to the allowance for credit losses, are conducted on an ongoing basis. These reviews consider such factors as the financial strength of borrowers and any guarantors, the value of the applicable collateral, loan loss experience, estimated credit losses, growth in the loan portfolio, prevailing economic conditions and other factors. Refer to Note 3 – Summary of Significant Accounting Policies, included herein, for additional discussion concerning the Bank’s policy for past due and nonperforming loans.

Reserve for Unfunded Loan Commitments

The allowance for off-balance sheet credit exposure relates to commitments to extend credit, letters of credit and undisbursed funds on lines of credit. The Company evaluates credit risk associated with the off-balance sheet loan commitments in the same manner as it evaluates credit risk associated with the loan and lease portfolio. The Bank's ACL methodology produced an allowance of $8.3 million for the off-balance sheet credit exposures as of December 31, 2025. There was $2.0 million in provision for unfunded loan commitments for the year ended December 31, 2025 and $1.25 million in recapture of for the year ended December 31, 2024. As of December 31, 2025 and December 31, 2024 the balance in this reserve was $8.3 million and $6.3 million, respectively, and was included in other liabilities.

Modifications of Loans to Borrowers Experiencing Financial Difficulty

The Company adopted ASU 2022-02, Financial Instruments - Credit Losses (Topic 326) Troubled Debt Restructurings and Vintage Disclosures effective January 1,2023. The amendments in ASU 2022-02 eliminated the recognition and measurement of troubled debt restructurings and enhanced disclosures for loan modifications to borrowers experiencing financial difficulty.

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of CVB Financial Corp. and subsidiaries (the Company) as of December 31, 2025 and 2024, the related consolidated statements of earnings and comprehensive income, stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2025, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2025, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 27, 2026 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

12. COMMITMENTS AND CONTINGENCIES

Commitments

At December 31, 2025 and 2024, the Bank had commitments to extend credit of approximately $1.87 billion and $1.72 billion, respectively, and obligations under letters of credit of $95.2 million and $60.0 million, respectively. Commitments to extend credit are agreements to lend to customers, provided there is no violation of any material condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Commitments are generally variable rate, and many of these commitments are expected to expire without being drawn upon. As such, the total commitment amounts do not necessarily represent future cash requirements. We use the same credit underwriting policies in granting or accepting such commitments or contingent obligations as we do for on-balance sheet instruments, which consist of evaluating customers’ creditworthiness individually. The Bank had a reserve for unfunded loan commitments of $8.3 million and $6.3 million as of December 31, 2025 and 2024, respectively, which is included in other liabilities.

Standby letters of credit are conditional commitments issued by the Bank to guarantee the financial performance of a customer to a third party. Those guarantees are primarily issued to support private borrowing or purchase arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. When deemed necessary, we hold appropriate collateral supporting those commitments. Management does not anticipate any material losses as a result of these transactions.

We invest in LIHTC, tax credit and other Community Reinvestment Act (“CRA”) related investments that call for capital contributions up to an amount specified in the partnership agreements. At December 31, 2025 and December 31, 2024, we had commitments to contribute capital to these entities totaling $77.5 million and $45.8 million.

Other Contingencies

The Company and its subsidiaries are parties to various lawsuits and threatened lawsuits in the course of business. From time to time, such lawsuits and threatened lawsuits may include, but are not limited to, actions involving securities litigation, employment matters, wage-hour and labor law claims, consumer claims, regulatory compliance claims, data privacy claims, lender liability claims, bankruptcy-related claims and negligence claims, some of which may be styled as “class action” or representative cases. Some of these lawsuits may be similar in nature to other lawsuits pending against the Company’s competitors.

For lawsuits where the Company has determined that a loss is both probable and reasonably estimable, a liability representing the best estimate of the Company’s financial exposure based on known facts has been recorded in accordance with FASB guidance over loss contingencies (ASC 450). However, as a result of inherent uncertainties in judicial interpretation and application of a myriad of laws and regulations applicable to the Company’s business, and the unique, complex factual issues presented in any given lawsuit, the Company often cannot determine the probability of loss or estimate the amount of damages which a plaintiff might successfully prove if the Company were found to be liable. For lawsuits or threatened lawsuits where a claim has been asserted or the Company has determined that it is probable that a claim will be asserted, and there is a reasonable possibility that the outcome will be unfavorable, the Company will disclose the existence of the loss contingency, even if the Company is not able to make an estimate of the possible loss or range of possible loss with respect to the action or potential action in question, unless the Company believes that the nature, potential magnitude or potential timing (if known) of the loss contingency is not reasonably likely to be material to the Company’s liquidity, consolidated financial position, and/or results of operations.

Our accruals and disclosures for loss contingencies are reviewed quarterly and adjusted as additional information becomes available. We disclose a loss contingency and/or the amount accrued if we believe it is reasonably likely to be material or if we believe such disclosure is necessary for our financial statements to not be misleading. If we determine that an exposure to loss exists in excess of an amount previously accrued or disclosed, we assess whether there is at least a reasonable possibility that a loss, or additional loss, may have been incurred, and we adjust our accruals and disclosures accordingly.

We do not presently believe that the ultimate resolution of any lawsuits currently pending against the Company will have a material adverse effect on the Company’s results of operations, financial condition, or cash flows. The outcome of litigation and other legal and regulatory matters is inherently uncertain, however, and it is possible that one or more of the legal matters currently pending or threatened against the Company could have a material adverse effect on our results of operations, financial condition or cash flows.

The Merger Agreement between the Company and Heritage contains certain termination rights for both CVB and Heritage providing that upon termination of the Merger Agreement under certain circumstances, CVB or Heritage, as applicable, will be obligated to pay the other party a termination fee of $32,450,000.

In each year, California income taxes comprise the majority of the state and local income taxes.

The Company invests in low income housing tax credit and solar tax funds that are designed to generate a return primarily through the realization of federal tax credits. The Company accounts for these investments by amortizing the cost of tax credit investments over the life of the investment using a proportional amortization method and tax credit investment amortization expense is a component of the provision for income taxes. For the year ended December 31, 2025, tax credits and other benefits recognized was $65.3 million and the tax credit amortization expense included in the provision for income taxes was $59.4 million.

The following table presents the balances of the Company's tax credit investments and related unfunded commitments at December 31, 2025 and 2024.

There were no significant unrecognized tax benefits at December 31, 2025 and 2024. We do not expect the total amount of unrecognized tax benefits to significantly increase or decrease within the next twelve months.

The Company is subject to income taxes in the federal, California, Arizona and three other non-material jurisdictions. The Company is no longer subject to examinations by taxing jurisdictions for periods before 2021, with the exception of California, for which the Company is no longer subject to examination for years before 2013.

At December 31, 2025, the Company has net operating loss (“NOL”) carryforwards of approximately $4.5 million for federal and $11.3 million California tax purposes, as a result of the acquisition of Suncrest Bank. The federal and California NOLs of approximately $3.0 million and $8.8 million, respectively, are subject to annual IRC Section 382 limitations of $3.4 million and have no expiration for federal tax purposes but will expire in 2032 for California if not utilized. The balance of the NOLs are subject to annual IRC Section 382 limitations of $314,000 and will begin to expire in 2030. At December 31, 2025, the Company has general business credit carryforwards of $3.5 million that will expire in 2045 if not utilized.

The Company considered the need for a valuation allowance on its deferred tax assets for the year ended December 31, 2025. The Company considered income in prior periods, projected future income, and projected future reversals of deferred tax items in making the determination that the deferred tax assets are more likely than not to be realized.

On June 27, 2025, California Senate Bill 132 (“SB 132”) was passed and signed into law by Governor Newsom. Effective for taxable years beginning on or after January 1, 2025, SB 132 amends California Revenue and Tax Code (“CRTC”) to require financial institutions to apportion income using the single sales factor formula. Prior to this change, businesses were required by CRTC Section 25128 (b) to use an evenly weighted three-factor apportionment formula contemplating a payroll factor, property and sales factor. The impact on the Company's tax expense as of December 31, 2025 is not material. The Company will continue to evaluate the impact of this bill on its deferred tax assets and liabilities.

The One Big Beautiful Bill Act (“OBBBA”) was signed and enacted into law on July 4, 2025. Except for certain provisions, this is effective for tax years beginning on or after January 1, 2025. Changes from OBBBA include modifications to allow for immediate expensing of certain business investments and provides certain permanent extensions of key business tax breaks originally enacted under the 2017 Tax Cuts and Job Act. All changes related to the 2025 provisions of OBBBA have been considered for Company's tax expense as of December 31, 2025, and are not material. Provisions applicable for periods beginning 2026 are not material to the financial statements.

Balance Sheet Offsetting

20. BALANCE SHEET OFFSETTING

Assets and liabilities relating to certain financial instruments including derivatives and securities sold under repurchase agreements (“repurchase agreements”), may be eligible for offset in the consolidated balance sheets as permitted under accounting guidance. As noted above, our interest rate swap derivatives are subject to master netting arrangements. Our interest rate swap derivatives require the Company to pledge investment securities as collateral based on certain risk thresholds. Investment securities that have been pledged by the Company to counterparties continue to be reported in the Company’s consolidated balance sheets unless the Company defaults. We offer a repurchase agreement product to our customers, which include master netting agreements that allow for the netting of collateral positions. This product, known as Citizens Sweep Manager, sells certain of our securities overnight to our customers under an agreement to repurchase them the next day. The repurchase agreements are not offset in the Company’s consolidated balances.

In June 2023, fair value hedging transactions were executed in which $1 billion notional pay-fixed interest rate swaps were consummated with maturities ranging from four to five years, wherein the Company pays a weighted average fixed rate of approximately 3.8% and receives daily SOFR. In December 2024, we terminated one of these swaps which had a notional value of $300 million, a maturity date of June 2027 and pay fixed rate of 3.95%. In May 2025, the remaining $700 million
notional pay-fixed interest rate swaps, with a weighted average fixed rate of approximately 3.7%, that were scheduled to
mature in June of 2028 were terminated and replaced with new pay-fixed interest rate swaps with maturity dates in May of
2029, 2030 and 2031, with a weighted pay-fixed rate of 3.68%. The new $700 million of fair value hedges have
approximately equal nominal values maturing each of the three years and had a fair value which totaled $8.6 million and was reflected as a liability on December 31, 2025. Refer to Note 18 – Derivative Financial Instruments of the notes to the consolidated financial statements of this report for additional information.

The following summarizes our analysis of these securities and the unrealized losses.

Government Agency & Government-Sponsored Enterprise — The government agency bonds are backed by the full faith and credit of agencies of the U.S. Government. While the Government-Sponsored Enterprise bonds are not expressly guaranteed by the U.S. Government, they are currently being supported by the U.S. Government under a conservatorship arrangement. These securities are bullet securities, that is, they have a defined maturity date on which the principal is paid. The contractual term of these investments provides that the Company will receive the face value of the bond at maturity which will equal the amortized cost of the bond. Interest is received throughout the life of the security. Accordingly, it is expected that the securities would not be settled at a price less than the amortized cost of the bonds.

MBS and CMO/REMIC — Most of the Company’s mortgage-backed and CMO/REMIC securities are issued by Government Agencies or Government-Sponsored Enterprises such as Ginnie Mae, Fannie Mae and Freddie Mac. These securities are collateralized or backed by the underlying residential or commercial mortgages. All mortgage-backed securities are considered to be rated investment grade with a weighted average life of approximately 6.5 years. Of the total MBS/CMO, 100% have the implied guarantee of U.S. Government-Sponsored Agencies and Enterprises. Accordingly, it is expected that the securities would not be settled at a price less than the amortized cost of the bonds. There were no credit-related impairments for the year ended December 31, 2025 and 2024.

Municipal Bonds — The majority of the Company’s municipal bonds, with maturities of approximately 12.0 years, represented approximately 9.7% of the total investment portfolio and are predominately AA or higher rated securities. The Company diversifies its holdings by owning selections of securities from different issuers and by holding securities from geographically diversified municipal issuers, thus reducing the Company’s exposure to any single adverse event. The decline in fair value is primarily due to the changes in interest rates. There were no credit-related impairments for the years ended December 31, 2025 and December 31, 2024.

Collateralized Loan Obligations (“CLO”) - The Company’s CLO portfolio consists of highly rated senior tranches backed by pool of loans, consisting of broadly syndicated corporate loans. These are variable rate securities that have an investment grade of AAA and carry sufficient credit enhancement. There were no credit-related impairment for the year ended December 31, 2025.

At December 31, 2025, investment securities with carrying values of $2.74 billion were pledged to secure various types of deposits. In addition, investment securities with carrying values of $2.0 billion were pledged to secure $548.6 million for repurchase agreements, $1.35 billion for unused borrowing capacity and approximately $57.0 million for other purposes as required or permitted by law.

At December 31, 2024, investment securities with carrying values of $2.79 billion were pledged to secure various types of deposits. In addition, investment securities with carrying values of $2.0 billion were pledged to secure $314.7 million for repurchase agreements, $1.63 billion for unused borrowing capacity and approximately $57.2 million for other purposes as required or permitted by law.

The amortized cost and fair value of debt securities at December 31, 2025, by contractual maturity, are shown in the table below. Although mortgage-backed and CMO/REMIC securities have weighted average remaining contractual

maturities of approximately 25 years, expected maturities will differ from contractual maturities because borrowers may have the right to prepay such obligations without penalty. Mortgage-backed and CMO/REMIC securities are included in maturity categories based upon estimated average lives which incorporate estimated prepayment speeds.

Customer Repurchase Agreements

The Bank offers a repurchase agreement product to its customers. This product, known as Citizens Sweep Manager, sells our investment securities overnight to our customers under an agreement to repurchase them the next day at a price which reflects the market value of the use of funds by the Bank for the period concerned. These repurchase agreements are signed with customers who want to invest their excess deposits, above a pre-determined balance in a demand deposit account, in order to earn interest. As of December 31, 2025, total funds borrowed under these agreements were $490.6 million with a weighted average interest rate of 1.72%, compared to $261.9 million with a weighted average interest rate of 0.72% at December 31, 2024.

Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	ITEM 1C. CYBERSECURITY Cyber criminals are becoming more sophisticated and effective every day, and they are increasingly targeting financial institutions and their customers. All companies utilizing technology are subject to threats and potential breaches of their cybersecurity programs. Any significant disruption in or unauthorized access to our computer systems or those of third parties that we utilize in our operations, including those relating to cybersecurity or arising from cyber-attacks, could result in a loss or degradation of service, unauthorized access, disclosure or destruction of data, including customer and bank information. To mitigate the threat to our business, we take a comprehensive approach to cybersecurity risk management and make securing the data customers and other stakeholders entrust to us a top priority. Our board of directors (the “Board”), through our Audit Committee, and our management, are actively involved in the oversight of our cybersecurity risk management program. As described in more detail below, we have established policies, standards, processes, practices and training for assessing, identifying, and managing material risks from cybersecurity threats. We have devoted significant financial and personnel resources to implement and maintain security measures to meet regulatory requirements and customer expectations, and we intend to continue to make significant investments to maintain the security of our data and cybersecurity infrastructure. There can be no guarantee that our policies, standards, processes, and procedures, and cybersecurity safeguards will be sufficient to protect against all possible threats and properly followed in every instance, or that those policies and procedures will be effective. Although our Risk Factors include further detail about the material cybersecurity risks we face, we believe that risks from prior cybersecurity threats, including as a result of any previous cybersecurity incidents, have not materially affected our business to date. We can provide no assurance that there will not be incidents in the future or that they will not materially affect us, including our business strategy, results of operations, or financial condition. Risk Management and Strategy Our policies, standards, processes and practices for assessing, identifying, and managing material risks from cybersecurity threats are integrated into our overall risk management program and are based on applicable banking regulations, including the Interagency Guidelines Establishing Information Security Standards (“Interagency Guidelines”), and a cybersecurity assessment framework. Our cybersecurity program in particular focuses on the following key areas: Process Our cybersecurity risks are identified and addressed through a cross-functional approach that includes coordination through our Corporate Information Security Committee, which includes senior managers in our information security, information technology, operations, risk, compliance and privacy departments or functions. Key security, operations, risk, compliance and privacy stakeholders meet regularly to develop strategies for preserving the confidentiality, integrity and availability of Company and customer information, identifying, preventing and mitigating cybersecurity threats, and effectively responding to cybersecurity incidents. We maintain controls and procedures that are designed to comply with applicable state and federal regulations to ensure prompt escalation of certain cybersecurity incidents so that decisions regarding public disclosure and reporting of such incidents can be made by management and our Board in a timely manner. Risk Assessment At least annually, we conduct a cybersecurity risk assessment that takes into account information from internal stakeholders, known information security vulnerabilities, and information from external sources (e.g., reported security incidents that have impacted other companies, industry trends, and evaluations by third parties and consultants). The results of the assessment are used to drive alignment on, and prioritization of, initiatives to enhance our security controls, make recommendations to improve processes, and inform a broader enterprise-level risk assessment that is presented to our Board, Audit Committee and members of management. Technical Safeguards We regularly assess and deploy technical safeguards designed to protect our information systems from cybersecurity threats. Such safeguards are regularly evaluated and improvements are made based on vulnerability assessments, cybersecurity threat intelligence and incident response experience. Incident Response, Recovery Planning and Disclosure Our Bank is subject to the Interagency Guidelines, as noted above, and our Company is subject to the SEC’s Rules on Cybersecurity Risk Management, Strategy, Governance, and Incident Disclosure by Public Companies adopted in July 2023. In accordance with these rules and regulations, we have sought to establish comprehensive incident response and recovery plans, and we continue to regularly test and evaluate the effectiveness of those plans. Our incident response and recovery plans address — and guide our employees, management and the Board on — our planned response to a cybersecurity incident. With respect to the potential disclosure of material cybersecurity incidents, we have designated our management Financial Review and Disclosure Committee as the proper forum to address such issues. Members of Financial Review and Disclosure Committee include the Chief Financial Officer (“CFO”), General Counsel, Chief Operating Officer (“COO”), Chief Risk Officer (“CRO”), and the Chief Information Security Officer (“CISO”). Third-Party Risk Management We have implemented controls designed to identify and mitigate cybersecurity threats associated with our use of third-party service providers, in the manner and to the extent required by our bank regulators and applicable regulations. Such third-party providers are subject to security risk assessments at the time of onboarding, and periodically reviewed as needed. We use a variety of inputs in such risk assessments, including information supplied by such third-party providers and other industry sources. In addition, we review our third-party providers security standards, controls and responsibilities to report on security incidents that have impacted their operations, as appropriate. Education and Awareness Our policies require each of our employees to participate in our data security efforts. We regularly remind employees of the importance of handling and protecting customer and employee data, including through annual privacy and security training to enhance employee awareness of how to detect and respond to cybersecurity threats. We also conduct regular phishing email exercises and training to test employees of security practices to mitigate this threat. External Assessments Our cybersecurity policies, standards, processes and practices are periodically assessed by third parties and internal and external auditors. These assessments include a variety of activities including information security maturity assessments, audits and independent reviews of our information security control environment and control effectiveness. These assessments are reported to senior management and our Board through its Audit Committee. Cybersecurity processes are adjusted based on the information provided from these assessments. Governance Board Oversight Our Board, through its Audit Committee, oversees the management of our cybersecurity program led by our CISO. The Audit Committee receives reports from management about the prevention, detection, mitigation, and remediation of cybersecurity threats and incidents, including material security risks and information security vulnerabilities. Specifically, the Audit Committee receives regular updates from our CISO on cybersecurity risk resulting from risk assessments, progress of risk reduction initiatives, internal and external auditor feedback, and any relevant internal and industry cybersecurity incidents. Management’s Responsibility The Bank's cybersecurity program is managed by our CISO, who reports to the Audit Committee. Management’s Corporate Information Security Committee (the “Security Committee”), led by our CISO, is a governance body that drives alignment on security decisions across multiple departments and functional areas within the Bank, while monitoring and managing Cyber risks to minimize exposure to the Bank. Members of the Security Committee include the Chief Information Officer (“CIO”), the CRO, and the COO. The Security Committee oversees processes for assessing, identifying, and managing material risks from cybersecurity threats. The Security Committee meets at least quarterly to review cybersecurity performance metrics, identify cybersecurity risks, and assess the status of approved cybersecurity enhancements. The Security Committee also considers and makes recommendations on cybersecurity policies and procedures, service requirements, and risk mitigation strategies. Our CISO has more than 29 years of Information Technology and 23 years of Information Security experience in financial services including similar roles at two other regional banks. He holds an undergraduate and master’s degree in Cybersecurity and Information Assurance. Our CIO has 27 years of information technology experience and 20 years of experience in the financial services industry. Our CRO has more than 35 years of experience in Banking and over 17 years of experience in risk management, compliance, and BSA. Our COO is a seasoned bank operations executive with over 37 years of banking experience in Operations, Vendor Management, IT, Security, Treasury Management and Payment Operations.

Fair Value Disclosures [Abstract]

Fair Value Information

17. FAIR VALUE INFORMATION

Fair Value Hierarchy

Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

The following disclosure provides the fair value information for financial assets and liabilities as of December 31, 2025. The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels (Level 1, Level 2 and Level 3).

•

Level 1 — Quoted prices in active markets for identical assets or liabilities in active markets that are accessible at the measurement date.

•

Level 2 — Observable inputs other than Level 1, including quoted prices for similar assets and liabilities in active markets, quoted prices in less active markets, or other observable inputs or model-derived valuations that can be corroborated by observable market data, either directly or indirectly, for substantially the full term of the financial instrument.

•

Level 3 — Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable. These valuation methodologies generally include pricing models, discounted cash flow models, or a determination of fair value that requires significant management judgment or estimation.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The tables below present the balances of assets and liabilities measured at fair value on a recurring basis for the dates presented.

Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis

We may be required to remeasure certain assets at fair value on a non-recurring basis in accordance with GAAP. These adjustments to fair value usually result from application of lower of cost or fair value accounting or write-downs of individual assets.

For assets measured at fair value on a non-recurring basis that were held on the balance sheet at December 31, 2025 and 2024, respectively, the following tables provide the level of valuation assumptions used to determine each adjustment and the carrying value of the related assets that had losses during the period. The fair values were determined using inputs based on observable market data or based on discounted cash flow criteria.

Fair Value of Financial Instruments

The following disclosure presents estimated fair value of our financial instruments. The estimated fair value amounts have been determined by the Company using available market information and appropriate valuation methodologies. However, considerable judgment is required to develop the estimates of fair value. Accordingly, the estimates presented below are not necessarily indicative of the amounts the Company may realize in a current market exchange as of December 31, 2025 and 2024, respectively. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts.

The following is a description of the valuation methodologies used to measure our Level 2 and Level 3 assets and liabilities recorded at fair value (under ASC Topic 820, “Fair Value Measurement”) and for estimating fair value for financial instruments not recorded at fair value (under ASC Topic 825).

Interest-earning balances due from depository institutions. The carrying amount is assumed to be the fair value given the short-term nature of these deposits.

Investment securities available-for-sale. Securities available-for-sale are measured and carried at fair value on a recurring basis. In determining the fair value of securities available-for-sale, we obtain a report from a nationally recognized broker-dealer detailing the fair value of each investment security we hold as of the reporting date. The broker-dealer used observable market information to value our securities, with the primary source being a nationally recognized pricing service. We review the market prices provided by the broker-dealer for our securities for reasonableness based on our understanding of the marketplace and we consider any credit issues related to the securities. As we have not made any adjustments to the market quotes provided to us and they are based on observable market data, they have been categorized as Level 2 within the fair value hierarchy.

Investment securities held-to-maturity. Securities held-to-maturity at carried at amortized cost. In determining the fair value of securities held-to-maturity, we use the same methodology as for securities available-for-sale and they have been categorized as Level 2 in the fair value hierarchy.

Total loans, net of allowance for credit losses. As loans and leases are not measured at fair value, the following discussion relates to estimating the fair value disclosures under ASC Topic 825. Loan fair values represent an exit price based upon the income approach. The loans are valued on an individual basis, with consideration given to the loans' underlying characteristics, including account types, remaining terms (in months), annual interest rates or coupons, interest types, past delinquencies, timing of principal and interest payments, current market rates, loan to value ratios, loss exposures, and remaining balances. Our model utilizes a discounted cash flow calculation to estimate the fair value of the loans using assumptions for the coupon rates, remaining maturities, prepayment speeds, projected default probabilities, loses given defaults, and estimates of prevailing discount rates. The discounted cash flow approach models the credit losses directly in the projected cash flows. The model applies various assumptions regarding credit, interest, and prepayment risks for the loans based on loan types, payment types and fixed or variable classifications. We typically classify loans as Level 3 in the fair value hierarchy.

Derivative assets and liabilities. Derivatives are carried at fair value on a recurring basis and primarily relate to forward contracts which we enter into to manage interest rate risk. Our derivatives are principally traded in over-the-counter markets where quoted market prices are not readily available. Instead, the fair value is estimated using market observable inputs such as current forward contract rates, interest rate yield curves, volatilities and basis spreads. We also consider counter-party credit risk in valuing our derivatives. We typically classify our derivative assets and liabilities as Level 2 in the fair value hierarchy.

Interest-bearing deposits. Interest-bearing deposits are carried at historical cost. The fair value of deposits with no stated maturity date is equal to the amount payable on demand as of the balance sheet date and considered Level 2. The fair value of time deposits is based on the discounted value of contractual cash flows and considered Level 2. The discount rate is estimated using the rates currently offered for deposits of similar remaining maturities. No value has been separately assigned to the Company's long-term relationships with its deposit customers, such as a core deposit intangible.

Borrowings. Borrowings may include FHLB advances and other fixed-rate term borrowings. Borrowings are carried at amortized cost. The fair value of fixed-rate borrowings is estimated by discounting scheduled cash flows through the maturity date or call date, if applicable, using estimated market discount rates that reflect current rates offered for borrowings with similar remaining maturities and characteristics and are considered Level 2 in the fair value hierarchy.

The fair value estimates presented herein are based on relevant market information and information about the financial instruments available to management as of December 31, 2025 and 2024. Changes in assumptions could significantly affect the estimates. Although management is not aware of any factors that would significantly affect the estimated fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since that date, and therefore, current estimates of fair value may differ significantly from the amounts presented above.

Share-Based Payment Arrangement [Abstract]

Stock Based Compensation Plans

15. STOCK-BASED COMPENSATION PLANS

In May 2018, the shareholders approved the 2018 Equity Plan which authorizes the issuance of up to 9,000,000 shares of CVB’s common stock for eligible participants, which include all of the Company’s employees, officers, and directors, and expires in 2028. The plan authorizes the issuance of a variety of types of equity awards, which include incentive stock options, non-qualified stock options, restricted stock awards, restricted stock units and other stock-based awards, including performance-based restricted stock units. The 2018 Equity Plan replaced the 2008 Equity Incentive Plan. No further grants will be made under the 2008 Equity Incentive Plan, but shares may continue to be issued under such plan pursuant to grants previously made. As of December 31, 2025, we have 1,530,595 outstanding options, unvested RSAs, RSUs and PRSUs under our Equity Plans.

Stock Options

The Company expensed $573,000, $477,000, and $384,000, for the years ended December 31, 2025, 2024 and 2023, respectively.

The estimated fair value of the options granted during 2025 and prior years was calculated using the Black-Scholes options pricing model. There were 55,300, 95,000 and 107,000 options granted during 2025, 2024 and 2023, respectively. The options will vest, in equal installments, over a five-year period. The fair value of each stock option granted in 2025, 2024 and 2023, was estimated on the date of grant using the following weighted-average assumptions.


	Year Ended December 31,
	2025			2024			2023
Dividend yield		4.3	%		4.7	%		3.2	%
Volatility		35.2	%		31.1	%		28.0	%
Risk-free interest rate		4.0	%		4.2	%		3.7	%
Expected life	10.0 years			10.0 years			10.0 years
Weighted average grant date fair value	$	7.67		$	8.70		$	11.09

The expected volatility is solely based on the daily historical stock price volatility over the expected option life. The expected life of options granted is derived from the output of the option valuation model and represents the period of time an optionee will hold an option before exercising it. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury five-year constant maturity yield curve in effect at the time of the grant. The Company accounts for forfeitures as they occur, rather than to estimate forfeitures over the vesting period.

The following table presents option activity under the Company’s stock option plans as of and for the year ended December 31, 2025.


	Number of Stock Options Outstanding			Weighted Average Exercise Price		Weighted Average Remaining Contractual Term		Aggregate Intrinsic Value
	(In thousands)					(In years)		(In thousands)
Outstanding at January 1, 2025		433		$	20.01
Granted		55			19.07
Exercised		(33	)		16.58
Forfeited or expired		(47	)		20.04
Outstanding at December 31, 2025		408		$	20.12		7.07	$	191
Vested or expected to vest at December 31, 2025		408		$	20.12		7.07	$	191
Exercisable at December 31, 2025		239		$	20.07		5.46	$	96

The total intrinsic value of options exercised during the years ended December 31, 2025, 2024 and 2023 was $146,000, $131,000 and $53,000, respectively.

As of December 31, 2025, there was a total of $1.2 million in unrecognized compensation cost related to nonvested options granted under the Plan. That cost is expected to be recognized over a weighted-average period of approximately 1.91 years. The total fair value of options vested was $457,000, $361,000 and $267,000 during 2025, 2024 and 2023, respectively. Cash received from stock option exercises was $383,000, $565,000 and $210,000, in 2025, 2024 and 2023, respectively.

At December 31, 2025, options for the purchase of 407,700 shares of CVB’s common stock were outstanding under the above plans, of which options to purchase 239,150 shares were exercisable at prices ranging from $16.62 to $24.83.

Restricted Stock Awards, Restricted Stock Units and Performance-Based Restricted Stock Units

The Company granted 424,000, 524,000 and 484,000 restricted stock awards during 2025, 2024 and 2023 respectively. The weighted average grant date fair value of RSAs, RSUs and PRSUs granted in 2025, 2024 and 2023 was $21.47 per share, $17.91 per share and $22.44 per share, respectively. These awards will vest, in equal installments, over a period of approximately one to five years.

Compensation cost is recognized over the requisite service period, which is approximately one to five years, and amounted to $9.2 million, $9.8 million and 9.1 million during the years ended December 31, 2025, 2024 and 2023, respectively. Total unrecognized compensation cost related to RSAs and PRSUs was $13.9 million at December 31, 2025.

The table below summarizes activity related to the Company’s non-vested RSAs and PRSUs for the year ended December 31, 2025.


	Shares				Weighted Average Grant-Date Fair Value
	(in thousands)
Nonvested at January 1, 2025		1,219			$	20.71
Granted		424				21.47
Vested		(462	)			21.07
Forfeited		(58	)			20.01
Nonvested at December 31, 2025		1,123		(1)	$	20.31

(1) Includes 237,857 PRSUs. There are no restricted stock units outstanding.

Under the 2018 Equity Incentive Plan, 3,715,125 shares of common stock were available for the granting of future stock-based awards as of December 31, 2025.

Regulatory Matters

16. REGULATORY MATTERS

The Company (on a consolidated basis) and the Bank are subject to various regulatory capital requirements administered by the federal banking regulatory agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary, actions by regulators that, if undertaken, could have a direct, material effect on the Company’s and the Bank’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and Bank must meet specific capital guidelines that involve quantitative measures of assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgment by the regulators about components, risk-weightings, and other factors. Prompt corrective action provisions are not applicable to bank holding companies.

The Company and the Bank are required to meet risk-based capital standards under the revised capital framework referred to as Basel III set by their respective regulatory authorities. The risk-based capital standards require the achievement of a minimum common equity Tier 1 (“CET1”) capital ratio of 4.5%, Tier 1 risk-based capital ratio of 6.0% and total risk-based capital ratio of 8.0%. In addition, the regulatory authorities require the highest rated institutions to maintain a minimum leverage ratio of 4.0%. To be considered “well-capitalized” for bank regulatory purposes, the Bank is required to have a Tier 1 leverage ratio equal to or greater than 5.0%, a CET1 capital ratio equal to or greater than 6.5%, a Tier 1 risk-based capital ratio equal to or greater than 8.0%, a total risk-based capital ratio equal to or greater than 10.0%. In addition to meeting the minimum capital requirements, under the Basel III Capital Rules, the Company and the Bank must also maintain the required Capital Conservation Buffer of 2.50% above the minimum risk-based capital requirements, which fully phased in by January 1, 2019. to avoid becoming subject to restrictions on capital distributions such as dividends and equity repurchases and certain discretionary bonus payments to management. At December 31, 2025 and 2024,, the Company and Bank were in compliance with the capital conservation buffer requirement and exceeded the minimum CET1, Tier 1, and total capital ratio, inclusive of the fully phased-in capital conservation buffer, of 7.00%, 8.50% and 10.50%, respectively, and the Bank qualified as “well capitalized” for purposes of the federal bank regulatory prompt corrective action regulations. There are no conditions or events that management believes have changed the Bank’s category.

The following table summarizes regulatory capital amounts and ratios for the Company and the Bank as of December 31, 2025 and 2024.

A national bank may not declare any cash dividend in an amount greater than the sum of current period net income and retained earnings. In addition, a national bank also must obtain prior approval from the OCC to pay a cash dividend if the dividend would exceed the sum of current period net income and retained earnings from the past two years, after deducting the following transactions during that period: (i) any dividends previously declared, (ii) extraordinary transfers required by the OCC, and (iii) payments made for the retirement of preferred stock. This calculation is performed on a rolling basis as described in the OCC’s earnings limitation regulations. The Bank could, as of December 31, 2025, declare and pay additional dividends of approximately $213.1 million without OCC approval.

Revenue from Contract with Customer [Abstract]

Revenue Recognition

22. REVENUE RECOGNITION

ASU No. 2014-09 “Revenue from Contracts with Customers (Topic 606)” and all subsequent ASUs that modified Topic 606 requires revenue that is derived from a contract with a customer to be recognized when the Company satisfies the related performance obligations by transferring to the customer a good or service.

Topic 606 does not apply to revenue associated with financial instruments, including interest and the gain/(loss) on the sale of loans and securities. In addition, certain noninterest income streams such as BOLI income and fees associated with mortgage servicing rights, financial guarantees, derivatives, and certain credit card fees are also not in scope of the new guidance. Topic 606 is applicable to noninterest revenue streams such as trust and asset management income, deposit related fees, interchange fees, and merchant income. However, the recognition of these revenue streams did not change significantly upon adoption of Topic 606. Noninterest revenue streams in-scope of Topic 606 are discussed below.

Trust and Investment Services

Trust and asset management income is primarily comprised of fees earned from the management and administration of trusts and customer assets. The Company’s performance obligation is generally satisfied over time and the resulting fees are recognized monthly, based upon the monthly market value of the assets under management and the applicable fee rate. Payment is generally received at month end through a direct charge to customers’ accounts. The Company does not earn performance-based incentives. Other services related to real estate and tax return preparation services are also provided to existing trust and asset management customers. The Company’s performance obligation for these transactional-based services is generally satisfied, and related revenue recognized, at a point in time (i.e., as incurred). Payment is received shortly after services are rendered.

Wealth Management contracts with customers have no clauses that would entitle customers to additional services. Fees are generally earned based on market value of assets under management and miscellaneous fees are transaction driven and are charged based on an agreed upon fee schedule. Performance obligation is satisfied upon execution of the transaction and there is no need to allocate transaction price to the performance obligation(s) in the contract. Wealth Management customers can also terminate the contract at will.

For Investment Services, the fees are earned based on services performed for customers as provided through an affiliated broker-dealer. Fees are earned from gross dealer commission based on trade date. Performance obligation is satisfied upon execution of the transaction and there is no need to allocate transaction price to the performance obligation(s) in the contract.

Deposit-related Fees

Service charges on deposit accounts consist of account analysis fees earned on analyzed business checking accounts, monthly service fees, and other deposit account related fees. The Company’s performance obligation for account analysis fees and monthly service fees is generally satisfied, and the related revenue recognized, over the period in which the service is provided. Other deposit account related fees are largely transactional based, and therefore, the Company’s performance obligation is satisfied, and related revenue recognized, at a point in time. Payment for service charges on deposit accounts is primarily received immediately or in the following month through a direct charge to customers’ accounts.

Bankcard Services

The Bank generates revenues from merchant servicing to its clients. A fee schedule is part of the contract and is calculated based on sales of merchants on a monthly basis. There is no future promise or claim to deliver services as merchant fees are based on monthly merchant transactions. The Company’s performance obligations are largely satisfied, and related revenue recognized, when the services are rendered or upon completion. Payment is typically received immediately or in the following month.

The following presents noninterest income, segregated by revenue streams in-scope and out-of-scope of Topic 606, for the periods presented.

Total noninterest income	$	55,171	$	54,474	$	59,330

Contract Acquisition Costs

In connection with the adoption of Topic 606, an entity is required to capitalize, and subsequently amortize into expense, certain incremental costs of obtaining a contract with a customer if these costs are expected to be recovered. The incremental costs of obtaining a contract are those costs that an entity incurs to obtain a contract with a customer that it would not have incurred if the contract had not been obtained (for example, sales commission). The Company utilizes the practical expedient, which allows entities to immediately expense contract acquisition costs when the asset that would have resulted from capitalizing these costs would have been amortized in one year or less.

- Definition
