We also have audited 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 (COSO). In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2025, and the results of its operations and its cash flows for the year ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework: (2013) issued by COSO. Basis for Opinion The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting . Our responsibility is to express an opinion on the Company’s financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects. Our audit of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures include examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions. ​ 66 Table of Contents Definitions and Limitations of Internal Control Over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of reliable financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate. Critical Audit Matter The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates. Allowance for Credit Losses – Loans As of December 31, 2025, the Company’s allowance for credit losses (“ACL”) totaled $21.5 million. The Company calculates its ACL in accordance with Topic 326, Financial Instruments – Credit Losses . As described in Notes 2 and 4 to the consolidated financial statements, the ACL for loans is separated between a collective reserve evaluation, for loans where similar risk characteristics exist, and an individual reserve evaluation for loans without similar risk characteristics. The collective quantitative ACL for loans is estimated using the remaining life or discounted cash flow (“DCF”) methodology based on the loan portfolio segment. In addition, for the collective reserve, management utilizes qualitative factors to adjust for current and expected conditions not captured within the quantitative loss estimates. The qualitative reserve is calculated using a combination of numeric frameworks and management judgement to determine risk categorizations in each of the qualitative factors. The amount of qualitative reserves is also contingent upon the historical peer, life-of-loan equivalent, loss rate ranges and the relative weighting of qualitative factors. We identified the Company’s estimate of the ACL, and more specifically the qualitative factor adjustments applied in the ACL, as a critical audit matter. The principal consideration for our determination is the subjectivity and judgment involved in management’s determination of credit loss estimates and assumptions (segment risk rating assigned), specifically for management’s determination of the changes in value of underlying collateral qualitative factor adjustment, management’s determination of the loan category and concentrations qualitative factor adjustment, and management’s determination of the use of peer loss/default levels in the DCF regression analysis qualitative factor assigned to each loan segment. Auditing these assumptions required increased auditor effort and a high degree of auditor subjectivity and judgment. 67 Table of Contents The primary procedures we performed to address this critical audit matter included: ● We obtained an understanding of the Company’s process for determining the ACL including the assumptions used to develop the qualitative factors mentioned, performed an ACL risk assessment to identify various components, data inputs, and assumptions utilized in the overall ACL model, and evaluated the design and implementation and tested operating effectiveness of controls relating to the ACL, including: o Controls over the completeness and accuracy of data input into the model used to determine the ACL. o Controls over management’s review and approval of the ACL, specifically focusing on management’s determination of the segment risk rating applied to the qualitative factor adjustments noted above, and applied within the qualitative framework of the overall ACL. ● We evaluated management’s determination of the mentioned qualitative adjustments, including : o Evaluated and tested the data, inputs and segment risk rating assumption utilized within the ACL calculation for completeness and accuracy including comparing key factors to independent sources as well as mathematical accuracy of the calculation driving the segment risk rating assigned. o Evaluated the reasonableness and adequacy of management’s qualitative factor adjustment framework and the application of the qualitative factor adjustments noted above within the framework associated with the qualitative factor scorecard risk rating assumptions against third-party or internal sources. o Evaluated the reasonableness of the segment risk rating related to the qualitative adjustments noted above by analyzing relevant trends in managements risk rating assumptions applied and evaluating the relationship of the trends to the qualitative adjustments applied to the ACL. ​ /s/ Forvis Mazars, LLP We have served as the Company’s auditor since 2025.

THE BUSINESS OF SIERRA BANCORP Sierra Bancorp (the “Company”) is a California corporation registered as a bank holding company under the Bank Holding Company Act of 1956, as amended, and is headquartered in Porterville, California. The Company was incorporated in November 2000 and acquired all of the outstanding shares of Bank of the Sierra (the “Bank”) in August 2001. The Company’s principal subsidiary is the Bank, and the Company exists primarily for the purpose of holding the stock of the Bank and its subsidiaries, two special purpose entities organized to facilitate repossessed assets, and of such other subsidiaries it may acquire or establish. The Company’s only other direct subsidiaries are Sierra Statutory Trust II, Sierra Capital Trust III, and Coast Bancorp Statutory Trust II, which were formed solely to facilitate the issuance of capital trust pass-through securities. At December 31, 2025, the Bank operated 34 full-service branch offices and provides specialized lending services through a Mortgage Warehouse lending division. The Bank’s deposits are insured by the Federal Deposit Insurance Corporation (FDIC) up to applicable legal limits. The Bank maintains a diversified loan portfolio comprised of commercial, real estate, construction, mortgage loans, consumer, and mortgage warehouse lines. Loans are primarily made in California within the market area of the South Central San Joaquin Valley, the Central Coast, Ventura County, and neighboring communities while mortgage warehouse customers are located throughout the United States. Our California footprint has diverse economies with principal industries being agriculture, real estate, oil and gas, service, government, healthcare, and light manufacturing. ​ 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Consolidation and Basis of Presentation The consolidated financial statements include the accounts of the Company and the accounts of its wholly owned subsidiary, Bank of the Sierra. All significant intercompany balances and transactions have been eliminated. Certain reclassifications have been made to prior years’ balances to conform to classifications used in 2025. The accounting and reporting policies of the Company conform to accounting principles generally accepted in the United States of America (U.S. GAAP) and prevailing practices within the banking industry. In accordance with U.S. GAAP, the Company’s investments in Sierra Statutory Trust II, Sierra Capital Trust III and Coast Bancorp Statutory Trust II are not consolidated and are accounted for under the equity method and included in other assets on the consolidated balance sheet. The subordinated debentures issued and guaranteed by the Company and held by the trusts are reflected on the Company’s consolidated balance sheet. The Bank has subsidiary interests in variable interest entities (“VIE”) for which the Bank does not have a controlling financial interest and is not the primary beneficiary. These subsidiary interests are not included in the Company’s consolidated financial statements. For additional information on the Bank’s interest in VIEs, see Note 23. Subsequent Events The Company has evaluated subsequent events for recognition and disclosure through February 27, 2025, which is the date the financial statements were available to be issued. Segment information An operating segment is generally defined as a component of business for which discrete financial information is available and whose operating results are regularly reviewed by the chief operating decision maker. As a community-oriented financial institution, substantially all of the Company’s operations involve the delivery of loan and deposit products to customers. The chief operating decision maker makes operating decisions and assesses performance based on an ongoing review of the Company’s community banking activities (loan and deposit products), which constitutes the Company’s only operating segment for financial reporting purposes. The Company’s single segment is managed on a consolidated basis by the chief operating decision maker, which is the Executive Committee, consisting of the chief executive officer, chief financial officer, chief risk officer, chief credit officer, chief operations officer, and chief banking 76 Table of Contents officer. The accounting policies of the community banking segment are the same as those described in the summary of significant accounting policies of the Company. The chief operating decision maker uses consolidated expense information to manage the operations of the segment. The consolidated expense information is the same as is reported on the income statement as consolidated net income. The measure of segment assets is reported on the balance sheet as total consolidated assets. The chief operating decision maker uses consolidated net income to evaluate income generated from segment assets (return on assets) in deciding whether to reinvest profits into the community banking segment or into other parts of the entity, such as for whole bank or branch acquisitions or to pay dividends. Net income is used to monitor budget versus actual results. The chief operating decision maker also uses net income in competitive analysis by benchmarking to the Company’s peer banking competitors. The competitive analysis along with the monitoring of budgeted versus actual results are used in assessing performance of the segment and in establishing management’s compensation. The Company does not have intra-entity revenues or transfers. Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and actual results could differ. Material estimates that are particularly susceptible to significant changes in the near-term relate to the determination of the allowance for credit losses, income taxes and deferred tax assets and liabilities, and goodwill. In connection with the determination of the allowances for credit losses and other real estate, management obtains independent appraisals for significant properties, evaluates the overall loan portfolio characteristics and delinquencies, and monitors economic conditions. Reclassifications Certain amounts in the Consolidated Income Statements for the prior periods have been reclassified to conform to the current presentation. The reclassifications had no effect on net income or stockholders’ equity as previously reported. Revision of Previously Issued Financial Statements Certain immaterial prior period amounts in the Consolidated Statement of Cash Flows have been revised and are reflected below. Specifically, cash flows from investing activities related to available-for-sale and held-to-maturity debt securities were combined on the Consolidated Statement of Cash Flows. These have been disaggregated and presented gross by classification. The changes were presentation only and had no impact on previously reported net income, total assets, total liabilities, or shareholders’ equity. The changes also had no impact on net cash provided by (used in) investing activities or total change in cash and cash equivalents. ​ 77 Table of Contents The effect of the above revision on previously reported financial statements is presented below (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As previously reported ​ ​ ​ Impact of Revision ​ ​ ​ As Revised Consolidated statement of cash flows for the year ended December 31, 2024 ​ ​ ​ ​ ​ ​ ​ ​ ​ Cash flows from investing activities: ​ ​ ​ ​ ​ ​ ​ ​ ​ Maturities and calls of debt securities available-for-sale ​ $ 100,194 ​ $ ( 170 ) ​ $ 100,024 Maturities and calls of debt securities held-to-maturity ​ ​ — ​ ​ 170 ​ ​ 170 Principal paydowns on debt securities available-for-sale ​ ​ 198,536 ​ ​ ( 15,126 ) ​ ​ 183,410 Principal paydowns on debt securities held-to-maturity ​ ​ — ​ ​ 15,126 ​ ​ 15,126 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Consolidated statement of cash flows for the year ended December 31, 2023 ​ ​ ​ ​ ​ ​ ​ ​ ​ Cash flows from investing activities: ​ ​ ​ ​ ​ ​ ​ ​ ​ Maturities and calls of debt securities available-for-sale ​ $ 71,065 ​ $ ( 795 ) ​ $ 70,270 Maturities and calls of debt securities held-to-maturity ​ ​ — ​ ​ 795 ​ ​ 795 Principal paydowns on debt securities available-for-sale ​ ​ 45,269 ​ ​ ( 16,968 ) ​ ​ 28,301 Principal paydowns on debt securities held-to-maturity ​ ​ — ​ ​ 16,968 ​ ​ 16,968 ​ Cash Flows For purposes of reporting cash flows, cash and cash equivalents include cash and deposits with other financial institutions with original maturities within 90 days, and federal funds sold. Net cash flows are reported for customer loan and deposit transactions, interest-bearing deposits in other financial institutions, and fed funds purchased and repurchase agreements. Securities Debt securities may be classified as held to maturity and carried at amortized cost when management has the positive ability and intent to hold them to maturity. Debt securities are classified as available for sale when they might be sold before maturity. Debt securities classified as available for sale are carried at fair value with unrealized holding gains and losses reported in other comprehensive income, net of tax. Securities designated as held-to-maturity, are carried at the amortized cost basis of the securities in question, which includes purchase premium or discount in addition to any unamortized premium or discount representing the unrealized gain or loss on any individual security at the time it was transferred from the available for sale designation. Notably, the Company has elected the practical expedient under GAAP to exclude accrued interest from the amortized-cost-basis of held-to-maturity securities and does not evaluate accrued interest receivable for an allowance for credit losses because any past due interest receivable on its held-to-maturity portfolio is reversed from income timely. Accrued interest on held-to-maturity securities and available-for-sale securities continues to be included in other assets on the Company’s balance sheet and measured $ 2.4 million and $ 4.8 million, respectively, as of December 31, 2025, and $ 2.4 million and $ 7.5 million, respectively, as of December 31, 2024. Interest income includes amortization of purchase premium or discount. Premiums or discounts on securities are amortized on the level-yield method without anticipating prepayments. Gains and losses on sales are recorded on the trade date and determined using the specific identification method. Management determines the appropriate classification of its investments at the time of purchase and may only change the classification in certain limited circumstances. All transfers between categories are accounted for at fair value. A debt security is placed on nonaccrual status at the time any principal or interest payments become 90 days delinquent. Interest accrued but not received for a security placed on non-accrual is reversed against interest income. 78 Table of Contents There were no debt securities past due or on nonaccrual in either available-for-sale or held-to-maturity for the years ended December 31, 2025 and December 31, 2024. For available-for-sale debt securities in an unrealized loss position for which management has an intent to sell the security or considers it more likely-than-not that the security in question will be sold prior to a recovery of its amortized cost basis, the security will be written down to fair value through a direct charge to income. For the remainder of available sale debt securities in an unrealized loss position, which don’t meet the previously outlined criteria, management evaluates whether the decline in fair value is a reflection of credit deterioration or other factors. In performing this evaluation, management considers the extent which fair value has fallen below amortized cost, changes in ratings by rating agencies, and other information indicating a deterioration in repayment capacity of either the underlying issuer or the borrowers providing repayment capacity in a securitization. If management’s evaluation indicates that a credit loss exists then a present value of the expected cash flows is calculated and compared to the amortized cost basis of the security in question and to the degree that the amortized cost basis exceeds the present value an allowance for credit loss (“ACL”) is established, with the caveat that the maximum amount of the reserve on any individual security is the difference between the fair value and amortized cost balance of the security in question. Any unrealized loss that has not been recorded through an ACL is recognized in other comprehensive income. At December 31, 2025, the Company had no recorded Allowance for Credit Losses on its securities designated as available-for-sale. On April 1, 2022, the Company transferred $ 162.1 million of Agency, Mortgaged-Backed, and Municipal securities from available-for-sale to held-to-maturity. On October 1, 2022, a similar transfer of $ 198.3 million securities from available for sale to held-to-maturity was completed. The securities were transferred at their fair value as of the transfer date, with the related unrealized gain or loss as of the date of transfer included in the amortized cost basis of the transferred security and subject to amortization or accretion over each security’s remaining life. An unrealized loss of $ 24.2 million, on securities transferred from the available-for-sale to held-to-maturity categorization, remains as of December 31, 2025, and is included in accumulated other comprehensive income, net of tax. Applying the Company’s combined marginal tax rate of 29.56 %, this amount reflects a tax-effected unrealized loss of approximately $ 17.1 million. As of December 31, 2024, and December 31, 2023, the gross unrealized loss was $ 26.3 million and $ 28.4 million, respectively. The year-over-year decrease in the unrealized loss is attributable to the ongoing accretion into income. The remaining unrealized loss on the securities transferred from available-for-sale to held-to-maturity, will be accreted over the remaining term of the securities, with the amortized-cost basis of these securities and accumulated comprehensive income each increasing over time. Under CECL, held-to-maturity debt securities are evaluated for reserves in a similar manner as loans. Because of the implicit and explicit guarantees of the Federal Government on the Agency and Mortgage-Backed, securities there is no expectation of future losses on any of these securities and no allowance for credit losses has been established for these securities. The Bank’s municipal bonds moved to the held-to-maturity designation all have credit ratings considered investment grade or equivalent. A discounted-cash-flow reserve calculation was performed upon the transfer of these securities into the held-to-maturity designation and is updated on a quarterly basis. FHLB Stock and Other Investments The Bank is a member of the Federal Home Loan Bank ("FHLB") system. Members are required to own a certain amount of stock based on the level of borrowings and other factors and may invest in additional amounts. FHLB stock is carried at cost in other assets and periodically evaluated for impairment based on the ultimate recovery of par value. Both cash and stock dividends are reported as income. The Bank’s investment in FHLB stock was approximately $ 14.7 million at December 31, 2025, and December 31, 2024. Loans (Financing Receivables) Our credit quality classifications of Loans include Pass, Special Mention, and Substandard. These classifications are defined in Note 4 to the consolidated financial statements. 79 Table of Contents Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported on the amortized cost basis and make up the entirety of the Company’s loan portfolio. The amortized cost basis of the Company’s loans is comprised of the principal balance outstanding, net of remaining deferred loan fees and costs, purchase premiums and discounts, and also net of any write-downs. Notably, the Company elected the practical expedient available under CECL to exclude accrued interest receivable from the amortized cost basis of all categorizations of loans and resultingly did not estimate reserves on accrued interest receivable balances, as any past due interest income is reversed on a timely basis. Accrued interest receivable on the Company’s loans continues to be included in other assets on the Company’s balance sheet and measured $ 7.0 million and $ 6.1 million as of December 31, 2025, and 2024, respectively. Loan origination fees, net of certain deferred origination costs, and purchase premiums and discounts are recognized in interest income as an adjustment to yield of the related loans over the contractual life of the loan using both the effective interest and straight-line methods without anticipating prepayments. Interest income for all performing loans, regardless of classification (Pass, Special Mention, Substandard), is accrued on unpaid principal balances, with interest accrued daily. Costs associated with successful loan originations are netted from loan origination fees, with the net amount (net deferred loan fees) amortized over the contractual life of the loan in interest income. If a loan has scheduled periodic payments, the amortization of the net deferred loan fee is calculated using the effective interest method over the contractual life of the loan. If the loan does not have scheduled payments, such as a line of credit, the net deferred loan fee is recognized as interest income on a straight-line basis over the contractual life of the loan. Fees received for loan commitments are recognized as interest income over the term of the commitment. When loans are repaid, any remaining unamortized balances of deferred fees and costs are accounted for through interest income. Generally, the Company places a loan or lease on nonaccrual status and ceases recognizing interest income when it has become delinquent more than 90 days and/or when Management determines that the repayment of principal and collection of interest is unlikely. The Company may decide that it is appropriate to continue to accrue interest on certain loans more than 90 days delinquent if they are well-secured by collateral and collection is in process. When a loan is placed on nonaccrual status, any accrued but uncollected interest for the loan is reversed out of interest income in the period in which the loan’s status changed. For loans with an interest reserve, i.e., where loan proceeds are advanced to the borrower to make interest payments, all interest recognized from the inception of the loan is reversed when the loan is placed on non-accrual. Once a loan is on non-accrual status subsequent payments received from the customer are applied to principal, and no further interest income is recognized until the principal has been paid in full or until circumstances have changed such that payments are again consistently received as contractually required. Generally, loans are not restored to accrual status until the obligation is brought current and has performed in accordance with the contractual terms for a reasonable period of time, and the ultimate collectability of the total contractual principal and interest is no longer in doubt. Due to loans being placed on nonaccrual status, $ 0.3 million of interest receivable on loans was reversed from interest income for the year ended December 31, 2025 and $ 0.2 million was reversed for the year ended December 31, 2024. Allowance for Credit Losses - Loans The Allowance for Credit Losses (“ACL”) on the loan portfolio is a valuation allowance deducted from the recorded balance in loans. The ACL represents principal which is not expected to be collected over the contractual life of the loans, adjusted for expected prepayment. The ACL is increased by a provision for credit losses charged to expense, and by principal recovered on charged-off balances. It is reduced by principal charge-offs. The amount of the allowance is based on management’s evaluation of the collectability of the loan portfolio, using information from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Adjustments are also made for changes in risk profile, credit concentrations, historical trends, and other economic conditions. The ACL for loans is separated between a collective reserve evaluation for loans where similar risk characteristics exist and an individual reserve evaluation for loans without similar risk characteristics. The collective evaluation of loans is performed at the portfolio segment level, using call code as the primary segmentation key but also considering similarity in quantitative reserve methodology. The Company’s ACL is categorized according to the 80 Table of Contents following portfolio segments: 1-4 Family Real Estate, Commercial Real Estate, Farmland & Agricultural Production, Commercial & Industrial, Mortgage Warehouse, and Consumer. Loans secured by 1-4 family residences have a different profile from loans secured by Commercial Real Estate. Generally, the borrowers for 1-4 Family loans are consumers whereas borrowers for Commercial Real Estate are often businesses. The COVID-19 pandemic illustrated how these different categories of real estate loans were subject to different risks, which was exacerbated by the widespread work-from-home model adopted by many companies during and since the pandemic. Farmland and Agricultural Production loans are included in a single segment as these loans are often times to the same borrowers, facing the same risks relating to commodity prices, water supply and drought conditions in addition to other environmental concerns. Commercial & Industrial loans are separated into a unique segment given the uniqueness of these loans, which are often revolving and secured by other business assets as opposed to real estate. Mortgage warehouse loans are also unique in the Company’s portfolio and warrant separate presentation as an individual portfolio segment, given the specific nature of these constantly revolving lines to mortgage originators and also attributable to a very limited loss history, even after consideration of peer data. Finally, the Company splits out Consumer loans as a separate segment as a result of the small balance, homogeneous terms that characterize these loans. Management utilizes a discounted cash flow methodology to estimate the quantitative portion of collectively evaluated reserves for the 1-4 Family Real Estate, Commercial Real Estate, Commercial & Industrial and Mortgage Warehouse portfolio segments. Management utilizes a Remaining Life Quantitative Reserve Methodology for the Farmland & Agricultural Production, and Consumer portfolio segments. Within the portfolio segments utilizing the DCF quantitative reserve methodology, management has made the election to adjust the effective interest rate to consider the impact of expected prepayments. Loans where similar risk characteristics exist are evaluated for the ACL in the collective reserve evaluation. The Company’s policy is that loans designated as nonaccrual no longer share risk characteristics similar to other loans evaluated collectively and as such, all nonaccrual loans are individually evaluated for reserves. As of December 31, 2025, the Bank’s nonaccrual loans comprised the entire population of loans individually evaluated. The Company’s policy is that nonaccrual loans also represent the subset of loans where borrowers are experiencing financial difficulty where an evaluation of the source of repayment is required to determine if the nonaccrual loan should be categorized as collateral dependent. It is the Company’s policy that the only loans where the credit quality has deteriorated to the point where foreclosure is probable are the Company’s nonaccrual loans. Most of the Company’s business activity is with customers located in California within the Southern Central San Joaquin Valley; in the corridor stretching between Santa Paula and Santa Clarita in Southern California, and on the Central Coast. Therefore, the Company’s exposure to credit risk is significantly affected by changes in the economy in those regions. The Company considers this concentration of credit risk when assessing and assigning qualitative factors in the allowance for credit. Though management believes the allowance for credit losses to be adequate, ultimate losses may vary from their estimates. However, estimates are reviewed periodically, and as adjustments become necessary, they are reported in earnings during the periods they become known. Allowance for Credit Losses - Off-Balance Sheet Commitments In addition to the exposure to credit loss from outstanding loans, the Company is also exposed to credit loss from certain off-balance sheet commitments such as unused commitments from revolving lines of credit, certain mortgage warehouse lines of credit, construction loans and commercial and standby letters of credit. Because the available funds have not yet been disbursed on these commitments the estimated losses are not included in the calculation of the allowance for credit losses on the loan portfolio. The implementation of CECL also impacted the Company’s ACL on unfunded loan commitments, as this ACL now represents expected credit losses over the contractual life of commitments not identified as unconditionally cancellable by the Company. The Reserve for Unfunded Commitments is estimated using the same reserve or coverage rates calculated on collectively evaluated loans following the application of a funding rate to the amount of the unfunded commitment. The funding rate represents management’s estimate of the amount of the current unfunded commitment that will be funded over the remaining contractual life of the commitment and is based on historical data. Under CECL, the ACL on unfunded loan commitments remains in Other Liabilities while any related provision expense has been moved to provision for credit loss expense from its prior presentation in noninterest expense. 81 Table of Contents Premises and Equipment Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets. The useful lives of premises range between twenty-five to thirty-nine years . The useful lives of furniture, fixtures, and equipment range between three to twenty years . Leasehold improvements are amortized over the life of the asset or the term of the related lease, whichever is shorter. When assets are sold or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts, and any resulting gain or loss is recognized in income for the period. The cost of maintenance and repairs is charged to expense as incurred. Impairment of long-lived assets is evaluated by management based upon an event or changes in circumstances surrounding the underlying assets which indicate long-lived assets may be impaired. Leases Leases are classified as operating or finance leases at the lease commencement date. The Company leases certain locations classified as operating leases. The Company records leases on the balance sheet in the form of a lease liability for the present value of future minimum payments under the lease terms and a right-of-use asset equal to the lease liability adjusted for items such as deferred or prepaid rent, lease incentives, and any impairment of the right-of-use asset. The discount rate used in determining the lease liability is based upon incremental borrowing rates the Company could obtain for similar loans as of the date of commencement or renewal. The Company does not record short term leases with an initial lease term of one year or less on the consolidated balance sheets. At lease inception, the Company determines the lease term by considering the noncancelable lease term and all optional renewal periods that the Company is reasonably certain to renew. The lease term is also used to calculate straight-line lease expense. Leasehold improvements are amortized over the shorter of the useful life and the estimated lease term. The Company’s leases do not contain residual value guarantees or material variable lease payments that will impact the Company's ability to pay dividends or cause the Company to incur additional expenses. Operating lease expense consists of a single lease cost allocated over the remaining lease term on a straight-line basis and variable lease expense. Lease expense is included in occupancy and equipment expense on the Company's consolidated statements of income. The Company's variable lease expense includes rent escalators that are based on market conditions and include items such as common area maintenance, utilities, parking, property taxes, insurance, and other costs associated with the lease. The amortization of the right-of-use asset arising from finance leases is expensed through occupancy and equipment expense. Transfers of Financial Assets Transfers of financial assets are accounted for as sales when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been legally isolated from the Company, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and the Company does not maintain effective control over the transferred assets. Foreclosed Assets Foreclosed assets include real estate and other property acquired in full or partial settlement of loan obligations. Upon acquisition, any excess of the recorded investment in the loan balance over the appraised fair market value, net of estimated selling costs, is charged against the allowance for credit losses on loans. A valuation allowance for losses on foreclosed assets is maintained to provide for subsequent declines in value. The allowance is established through a provision for losses on foreclosed assets which is included in other noninterest expense. Subsequent gains or losses on sales or write-downs resulting from permanent impairments are recorded in other noninterest expense as incurred. Operating costs after acquisition are expensed. 82 Table of Contents The Company had one foreclosed property with a fair value of $ 1.6 million recorded at December 31, 2025. At December 31, 2025, there were no consumer mortgage loans secured by residential real estate properties for which formal foreclosure proceeds were in process. Goodwill and Other Intangible Assets The Company acquired Sierra National Bank in 2000, Santa Clara Valley Bank in 2014, Coast National Bank in 2016, and Ojai Community Bank and the Woodlake Branch of Citizen’s Business Bank in 2017. 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 noncontrolling interests 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 which indicate that an impairment test should be performed. The Company selected October 1, 2025, as the date to perform the annual impairment test for 2025. Goodwill is the only intangible asset with an indefinite life on our balance sheet. There was no impairment recognized for the years ended December 31, 2025, 2024, and 2023. Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. The Company’s other intangible assets consist solely of core deposit intangible assets (CDI’s) arising from the acquisitions of Santa Clara Valley Bank, Coast National Bank, Ojai Community Bank, the Woodlake Branch of Citizen’s Business Bank, and the Lompoc branch of Santa Maria Community Bank. All of the CDI’s are being amortized on a straight-line basis over eight years . Loan Commitments and Related Financial Instruments Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded. Details regarding these commitments and financial instruments are discussed in detail in Note 14 to the consolidated financial statements. Income Taxes The Company files its income taxes on a consolidated basis with its subsidiary. The allocation of income tax expense represents each entity’s proportionate share of the consolidated provision for income taxes. Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax basis of assets and liabilities, computed using enacted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely to be realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. We have determined that as of December 31, 2025, all tax positions taken to date are highly certain and, accordingly, no accounting adjustment has been made to the financial statements. The Company recognizes interest and penalties related to uncertain tax positions as part of income tax expense. ​ 83 Table of Contents Company Owned Life Insurance (General Account) The Company has purchased life insurance policies on certain key executives and officers. Company owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement. Bank Owned Life Insurance (Separate Account) Bank-owned life insurance (“BOLI”) is “separate account” which consists of specific directed investments in underlying assets (generally equity and bond funds) that closely mirror investment choices of deferred compensation participants. Deferred compensation participants can make investment choices similar to a traditional 401k plan; as the deferred compensation plan is a nonqualified plan, the liability is a corporate liability. To offset this deferred compensation plan, the Company has chosen to use separate account BOLI designed to be an economic hedge against deferred compensation. Therefore, the income on BOLI generally offsets the deferred compensation expense each year. The separate account BOLI earnings are decreased by the underlying cost of life insurance, however, the earnings on separate account BOLI income are tax-free, whereas the related deferred compensation expense is tax deductible. Salary Continuation Agreements and Directors’ Retirement Plan The Company has entered into agreements to provide members of the Board of Directors and certain key executives, or their designated beneficiaries, with annual benefits for up to fifteen years after retirement or death. The Company accrues for these future benefits from the effective date of the plan until the director’s or executive’s expected retirement date in a systematic and rational manner. At the consolidated balance sheet date, the amount of accrued benefits equals the then present value of the benefits expected to be provided to the director or employee, any beneficiaries, and covered dependents in exchange for the director’s or employee’s services to that date. Comprehensive Income Comprehensive income consists of net income and other comprehensive income. Other comprehensive income includes fluctuations in unrealized gains and losses on securities available for sale, net of an adjustment for the effects of realized gains and losses and any applicable tax. Comprehensive income is a more inclusive financial reporting methodology that includes disclosure of other comprehensive income that historically has not been recognized in the calculation of net income. Unrealized gains and losses on the Company’s available for sale securities, net of tax, are included in other comprehensive income after adjusting for the effects of realized gains and losses. Total comprehensive income and the components of accumulated other comprehensive income are presented in the consolidated statements of comprehensive income. Stock-Based Compensation At December 31, 2025, the Company had one active stock-based compensation plan, the Sierra Bancorp 2023 Equity Compensation Plan (the “2023 Plan”), which was adopted by the Company’s Board of Directors on March 17, 2023, and approved by the Company’s shareholders on May 24, 2023. The 2023 Plan replaced the Company’s 2017 Stock Incentive Plan (the “2017” Plan), which expired by its own terms on March 16, 2023. Unvested restricted stock and options to purchase shares granted under the 2017 Plan and its predecessor the 2007 Stock Incentive Plan (the “2007” Plan) that remained outstanding were unaffected by that plan’s termination. The 2023 Plan covers 360,000 shares of the Company’s authorized but unissued common stock, subject to adjustment for stock splits and dividends, and provides for the issuance of both “incentive” and “nonqualified” stock options to salaried officers and employees, and of “nonqualified” stock options to non-employee directors. The 2023 Plan also provides for the issuance of restricted stock awards to these same classes of eligible participants. Compensation cost and director’s expense is recognized for stock options and restricted stock awards issued to employees and directors and is recognized over the required service period, generally defined as the vesting period. The Company utilized the Black-Scholes model to estimate the fair value of stock options, while the market price 84 Table of Contents of the Company’s common stock at the date of grant is used for restricted stock awards. The “multiple option” approach for stock options is used to allocate the resulting valuation to actual expense for current period. Expected volatility is based on historical volatility of the Company’s common stock. The Company uses historical data to estimate stock option exercise and post-vesting termination behavior. The expected term of stock options granted is based on historical data and represents the period of time that options granted are expected to be outstanding subsequent to vesting, which takes into account that the options are not transferable. The risk-free interest rate for the expected term of the stock option is based on the U.S. Treasury yield curve in effect at the time of the grant. No stock options were granted during the years ended December 31, 2025, 2024, and 2023. Low Income Housing Tax Credit (LIHTC) Partnerships The Company’s LITHCs are indirect federal subsidies to finance low-income housing and are used in connection with both newly constructed and renovated residential rental buildings. Once a project is placed in service, it is generally eligible for the tax credit for ten years. To continue generating the tax credit and to avoid tax credit recapture, a LIHTC building must satisfy specific low-income housing compliance rules for a full fifteen years. The maximum exposure to loss in the VIEs is the amount of equity invested, and credit extended by the Company. The Company has evaluated the variable interests held by the Company in each LIHTC investment and determined that the Company does not have controlling financial interests in such investments and is not the primary beneficiary. The Company reports the investments in the unconsolidated LIHTCs as other assets on the Company’s statements of financial condition. Revenue Recognition Revenue from contracts with customers subject to ASC 606 comprises the noninterest income earned by the Company in exchange for services provided to customers. Income associated with customer contracts generally involve transaction prices that are fixed and performance obligations which are satisfied as services are rendered. In most cases recognition occurs within a single financial reporting period as there is little or no judgement involved in the timing of revenues. We generally act in a principal capacity, on our own behalf, in most of our contracts with customers. In such transactions, we recognize revenue and the related costs to provide our services on a gross basis in our financial statements. Service Charges on Deposit Accounts comprise charges on retail and business accounts. Business customers can earn credits depending on account type and deposit balances maintained with the Company, which may be used to offset fees. Fees and credits are based on predetermined, agreed-upon rates. In some cases, we act in an agent capacity, deriving revenue through assisting other entities in transactions with our customers. In such transactions, we recognize revenue and those related costs to provide services on a gross basis in our financial statements. Debit card interchange income is derived from our customers’ use of various interchange and ATM/debit card networks which are the primary sources of revenue generated in an agent capacity. Recently Adopted Accounting Pronouncements In March 2023, the FASB issued ASU No. 2023-02, “Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method.” ASU 2023-02 is intended to improve the accounting and disclosures for investments in tax credit structures. ASU 2023-02 allows entities to elect to account for qualifying tax equity investments using the proportional amortization method, regardless of the program giving rise to the related income tax credits. Previously, this method was only available for qualifying tax equity investments in low-income housing tax credit structures. ASU 2023-02 was adopted by the Company on January 1, 2024, and its adoption did not have a significant effect on the Company’s financial statements. In November 2023, the FASB issued ASU No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” ASU 2023-07 expands segment disclosure requirements for public entities to require disclosure of significant segment expenses and other segment items on an annual and interim basis and to provide in interim periods all disclosures about a reportable segment’s profit or loss and assets that are currently required annually. ASU 2023-07 was adopted by the Company in 2024, and its adoption did not have a significant impact on our financial statements. 85 Table of Contents In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” ASU 2023-09 requires public business entities to disclose in their rate reconciliation table additional categories of information about federal, state, and foreign income taxes and to provide more details about the reconciling items in some categories if items meet a quantitative threshold. ASU 2023-09 also requires all entities to disclose income taxes paid, net of refunds, disaggregated by federal, state, and foreign taxes for annual periods and to disaggregate the information by jurisdiction based on a quantitative threshold, among other things. ASU 2023-09 was adopted by the Company prospectively on January 1, 2025. ASU 2023-09 did not have a significant impact on our financial statements. ​ Recent Accounting Pronouncements On October 9, 2023, the FASB issued ASU 2023-06, “Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification of Initiative.” ASU 2023-06 amends the disclosure or presentation requirements related to various subtopics in the FASB Accounting Standards Codification (the “Codification”). The ASU was issued in response to the SEC’s August 2018 final rule that updated and simplified disclosure requirements that the SEC believed were “redundant, duplicative, overlapping, outdated, or superseded.” The new guidance is intended to align U.S. GAAP requirements with those of the SEC and to facilitate the application of U.S. GAAP for all entities. ASU 2023-06 applies to all reporting entities within the scope of the amended subtopics. Note that some of the amendments introduced by the ASU are technical corrections or clarifications of the FASB’s current disclosure or presentation requirements. The effective date for each amendment of ASU 2023-06 will be the date on which the SEC’s removal of that related disclosure requirement from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. The Company will apply the amendments in ASU 2023-06 prospectively after the effective dates. The adoption of this standard is not expected to have a significant effect on the Company’s financial statements. ​ In November 2024, the FASB issued ASU 2024-03, “Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40).” ASU 2024-03 requires public business entities to disclose specific information about certain costs and expenses in the notes to its financial statements for interim and annual reporting periods. The objective of the disclosure requirements is to provide disaggregated information about a public business entity's expenses to help investors (a) better understand the entity's performance, (b) better assess the entity's prospects for future cash flows, and (c) compare an entity's performance over time and with that of other entities. ASU 2024-03 is effective for us in annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption of Update 2024-03 is permitted. ASU 2024-03 is not expected to have a significant impact on our financial statements. ​ ​ 3. INVESTMENT SECURITIES Pursuant to FASB’s guidance on accounting for debt securities, available for sale securities are carried on the Company’s financial statements at their estimated fair market values, with monthly tax-effected “mark-to-market” adjustments made vis-à-vis accumulated other comprehensive income in shareholders’ equity. Held-to-maturity securities are carried on the Company’s financial statements at their amortized cost, net of the allowance for credit losses. ​ 86 Table of Contents The amortized cost and fair value of the securities available-for-sale and held-to-maturity are as follows (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2025 ​ ​ ​ ​ Amortized Cost ​ ​ ​ Gross Unrealized Gains ​ ​ ​ Gross Unrealized Losses ​ Allowance for Credit Losses ​ ​ ​ Estimated Fair Value Available-for-sale ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. government agencies ​ $ 33,000 ​ $ 35 ​ $ ( 134 ) ​ $ — ​ $ 32,901 Mortgage-backed securities ​ ​ 259,386 ​ ​ 2,491 ​ ​ ( 2,117 ) ​ ​ — ​ ​ 259,760 State and political subdivisions ​ ​ 52,610 ​ ​ 68 ​ ​ ( 5,757 ) ​ ​ — ​ ​ 46,921 Corporate bonds ​ ​ 90,114 ​ ​ 293 ​ ​ ( 3,940 ) ​ ​ — ​ ​ 86,467 Collateralized loan obligations ​ ​ 198,968 ​ ​ 364 ​ ​ ( 51 ) ​ ​ — ​ ​ 199,281 Total available-for-sale securities ​ $ 634,078 ​ $ 3,251 ​ $ ( 11,999 ) ​ $ — ​ $ 625,330 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Amortized Cost ​ Gross Unrecognized Gains ​ Gross Unrecognized Losses ​ Estimated Fair Value ​ Allowance for Credit Losses Held-to-maturity ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. government agencies ​ $ 4,523 ​ $ — ​ $ ( 413 ) ​ $ 4,110 ​ $ — Mortgage-backed securities ​ ​ 115,228 ​ ​ 20 ​ ​ ( 7,002 ) ​ ​ 108,246 ​ ​ — State and political subdivisions ​ ​ 171,075 ​ ​ 3,030 ​ ​ — ​ ​ 174,105 ​ ​ ( 15 ) Total held-to-maturity securities ​ $ 290,826 ​ $ 3,050 ​ $ ( 7,415 ) ​ $ 286,461 ​ $ ( 15 ) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2024 ​ ​ ​ ​ Amortized Cost ​ ​ ​ Gross Unrealized Gains ​ ​ ​ Gross Unrealized Losses ​ Allowance for Credit Losses ​ ​ ​ Estimated Fair Value Available-for-sale ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. government agencies ​ $ 50,761 ​ $ — ​ $ ( 608 ) ​ $ — ​ $ 50,153 Mortgage-backed securities ​ ​ 97,113 ​ ​ 116 ​ ​ ( 3,726 ) ​ ​ — ​ ​ 93,503 State and political subdivisions ​ ​ 48,119 ​ ​ 7 ​ ​ ( 7,323 ) ​ ​ — ​ ​ 40,803 Corporate bonds ​ ​ 66,308 ​ ​ — ​ ​ ( 7,746 ) ​ ​ — ​ ​ 58,562 Collateralized loan obligations ​ ​ 411,729 ​ ​ 1,217 ​ ​ — ​ ​ — ​ ​ 412,946 Total available-for-sale securities ​ $ 674,030 ​ $ 1,340 ​ $ ( 19,403 ) ​ $ ​ ​ $ 655,967 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Amortized Cost ​ Gross Unrecognized Gains ​ Gross Unrecognized Losses ​ Estimated Fair Value ​ Allowance for Credit Losses Held-to-maturity ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. government agencies ​ $ 4,819 ​ $ — ​ $ ( 592 ) ​ $ 4,227 ​ $ — Mortgage-backed securities ​ ​ 128,974 ​ ​ — ​ ​ ( 13,986 ) ​ ​ 114,988 ​ ​ — State and political subdivisions ​ ​ 171,736 ​ ​ 229 ​ ​ ( 152 ) ​ ​ 171,813 ​ ​ ( 15 ) Total held-to-maturity securities ​ $ 305,529 ​ $ 229 ​ $ ( 14,730 ) ​ $ 291,028 ​ $ ( 15 ) ​ The Company did not record an ACL on the available-for-sale portfolio at December 31, 2025, or upon the implementation of CECL on January 1, 2022. As of both dates the Company considers the unrealized loss across the classes of major security-type to be related to fluctuations in market conditions, primarily interest rates, and not reflective of a deterioration in credit value. The Company maintains that it has intent and ability to hold these securities until the amortized cost basis of each security is recovered and likewise concluded as December 31, 2025, that it was not more likely than not that any of the securities in an unrealized loss position would be required to be sold. For the years ended December 31, 2025, 2024, and 2023, proceeds from sales of securities available-for-sale were $ 3.0 million, $ 233.2 million, and $ 25.7 million, respectively. Gains and losses on the sale of investment securities are recorded on the trade date and are determined using the specific identification method. 87 Table of Contents Gross gains and losses from the sales and calls of securities for the years ended were as follows (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, ​ ​ ​ ​ 2025 ​ ​ ​ 2024 ​ ​ ​ 2023 Gross gains on sales and calls of securities ​ $ 126 ​ $ 220 ​ $ 396 Gross losses on sales and calls of securities ​ ​ ( 6 ) ​ ​ ( 2,901 ) ​ ​ — Net gains (losses) on sales and calls of securities ​ $ 120 ​ $ ( 2,681 ) ​ $ 396 ​ The Company has reviewed all sectors and securities in the portfolio for impairment. During the year ended December 31, 2025, the Company realized gains through earnings from the sale and call of 73 debt securities for $ 0.1 million and one debt security for which a loss was realized. During the year ended December 31, 2024, the Company realized gains through earnings from the sale and call of eight debt securities for $ 0.2 million. The securities were sold with 100 other debt securities, for which a $ 2.9 million loss was realized. During the year ended December 31, 2023, the Company realized gains through earnings from the sale and call of 37 debt securities for $ 0.4 million. The Company recognized a $ 14.5 million loss for the year ended December 31, 2023, on investment securities intended for sale and subsequently sold in January 2024. Included in this sale were $ 4.0 million in U.S. government agencies, $ 74.8 million in mortgage-backed securities, and $ 117.9 million in state and political subdivisions. The following table summarizes available-for-sale debt securities that were in an unrealized loss position for which an ACL has not been recorded, based on the length of time the individual securities have been in an unrealized loss position, including the number of available-for-sale debt securities in an unrealized loss position, as of the dates indicated below (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2025 ​ ​ ​ Less than twelve months ​ Twelve months or longer ​ Total ​ Number of Securities ​ ​ ​ Gross Unrealized Losses ​ ​ ​ Fair Value ​ ​ ​ Gross Unrealized Losses ​ ​ ​ Fair Value ​ ​ ​ Gross Unrealized Losses ​ ​ ​ Fair Value Available-for-sale ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. government agencies 5 ​ $ ( 10 ) ​ $ 5,990 ​ $ ( 124 ) ​ $ 14,375 ​ $ ( 134 ) ​ $ 20,365 Mortgage-backed securities 72 ​ ​ ( 755 ) ​ ​ 92,185 ​ ​ ( 1,362 ) ​ ​ 28,712 ​ ​ ( 2,117 ) ​ ​ 120,897 State and political subdivisions 51 ​ ​ ( 14 ) ​ ​ 1,481 ​ ​ ( 5,743 ) ​ ​ 37,029 ​ ​ ( 5,757 ) ​ ​ 38,510 Corporate bonds 70 ​ ​ ( 483 ) ​ ​ 25,381 ​ ​ ( 3,457 ) ​ ​ 41,993 ​ ​ ( 3,940 ) ​ ​ 67,374 Collateralized loan obligations 7 ​ ​ ( 51 ) ​ ​ 59,209 ​ ​ — ​ ​ — ​ ​ ( 51 ) ​ ​ 59,209 Total available-for-sale 205 ​ $ ( 1,313 ) ​ $ 184,246 ​ $ ( 10,686 ) ​ $ 122,109 ​ $ ( 11,999 ) ​ $ 306,355 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2024 ​ ​ ​ Less than twelve months ​ Twelve months or longer ​ Total ​ Number of Securities ​ ​ ​ Gross Unrealized Losses ​ ​ ​ Fair Value ​ ​ ​ Gross Unrealized Losses ​ ​ ​ Fair Value ​ Gross Unrealized Losses ​ Fair Value Available-for-sale ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. government agencies 11 ​ $ ( 608 ) ​ $ 48,155 ​ $ — ​ $ — ​ $ ( 608 ) ​ $ 48,155 Mortgage-backed securities 54 ​ ​ ( 2,952 ) ​ ​ 64,419 ​ ​ ( 774 ) ​ ​ 8,032 ​ ​ ( 3,726 ) ​ ​ 72,451 State and political subdivisions 52 ​ ​ ( 33 ) ​ ​ 3,087 ​ ​ ( 7,290 ) ​ ​ 34,612 ​ ​ ( 7,323 ) ​ ​ 37,699 Corporate bonds 52 ​ ​ ( 12 ) ​ ​ 1,359 ​ ​ ( 7,734 ) ​ ​ 55,653 ​ ​ ( 7,746 ) ​ ​ 57,012 Total available-for-sale 169 ​ $ ( 3,605 ) ​ $ 117,020 ​ $ ( 15,798 ) ​ $ 98,297 ​ $ ( 19,403 ) ​ $ 215,317 ​ 88 Table of Contents The amortized cost and estimated fair value of investment securities available-for-sale and held-to-maturity at December 31, 2025, by contractual maturity are shown below.

Securities with amortized costs totaling $ 420.4 million and carrying values totaling $ 403.4 million were pledged to secure other contractual obligations and short-term borrowing arrangements at December 31, 2024 (see Note 10). At December 31, 2025, the Company’s investment portfolio included securities issued by 199 different government municipalities and agencies located within 28 states with a fair value of $ 221.0 million. The largest exposure to any single municipality or agency was $ 5.2 million (fair value) in four general obligation bonds issued by the City of New York (NY). In addition, the Company owned 109 subordinated debentures issued by bank holding companies totaling $ 86.5 million (fair value). At December 31, 2024, the Company’s investment portfolio included securities issued by 188 different government municipalities and agencies located within 28 states with a fair value of $ 212.6 million. The largest exposure to any single municipality or agency was $ 5.1 million (fair value) in four general obligation bonds issued by the City of New York (NY). In addition, the Company owned 56 subordinated debentures issued by bank holding companies totaling $ 58.6 million (fair value). The Company’s investments in bonds issued by states, municipalities and political subdivisions are evaluated in accordance with Supervision and Regulation Letter 12-15 (SR 12-15) issued by the Board of Governors of the Federal Reserve System, “Investing in Securities without Reliance on Nationally Recognized Statistical Rating Organization Ratings,” and other regulatory guidance. Credit ratings are considered in our analysis only as a guide to the historical default rate associated with similarly rated bonds. There have been no significant differences in our internal analyses compared with the ratings assigned by the third-party credit rating agencies. 89 Table of Contents The following table summarizes the amortized cost and fair values of general obligation and revenue bonds in the Company’s investment securities portfolio at the indicated dates, identifying the state in which the issuing municipality or agency operates for our largest geographic concentrations (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2025 ​ December 31, 2024 General obligation bonds ​ ​ ​ Amortized Cost ​ ​ ​ Fair Value ​ ​ ​ Amortized Cost ​ ​ ​ Fair Value State of Issuance: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Texas ​ $ 86,922 ​ $ 85,424 ​ $ 82,769 ​ $ 79,472 California ​ ​ 50,945 ​ ​ 49,130 ​ ​ 51,222 ​ ​ 48,131 Other (22 and 22 states, respectively) ​ ​ 60,220 ​ ​ 61,092 ​ ​ 60,422 ​ ​ 60,169 Total general obligation bonds ​ ​ 198,087 ​ ​ 195,646 ​ ​ 194,413 ​ ​ 187,772 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Revenue bonds ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ State of Issuance: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Texas ​ ​ 5,534 ​ ​ 5,378 ​ ​ 5,434 ​ ​ 5,261 California ​ ​ 3,583 ​ ​ 3,586 ​ ​ 3,576 ​ ​ 3,440 Other (13 and 11 states, respectively) ​ ​ 16,481 ​ ​ 16,416 ​ ​ 16,432 ​ ​ 16,143 Total revenue bonds ​ ​ 25,598 ​ ​ 25,380 ​ ​ 25,442 ​ ​ 24,844 Total obligations of states and political subdivisions ​ $ 223,685 ​ $ 221,026 ​ $ 219,855 ​ $ 212,616 ​ The following table summarizes the amortized cost and fair value of revenue bonds in the Company’s investment securities portfolio at the indicated dates, identifying the revenue source of repayment for our largest source concentrations (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2025 ​ December 31, 2024 Revenue bonds ​ ​ ​ Amortized Cost ​ ​ ​ Fair Value ​ ​ ​ Amortized Cost ​ ​ ​ Fair Value Revenue Source: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Water ​ $ 9,274 ​ $ 9,059 ​ $ 9,194 ​ $ 8,892 Sewer ​ ​ 3,713 ​ ​ 3,801 ​ ​ 3,613 ​ ​ 3,755 Lease ​ ​ 3,910 ​ ​ 4,158 ​ ​ 3,923 ​ ​ 4,141 Sales tax ​ ​ 1,687 ​ ​ 1,676 ​ ​ 1,688 ​ ​ 1,588 Other (10 and 6 sources, respectively) ​ ​ 7,014 ​ ​ 6,686 ​ ​ 7,024 ​ ​ 6,468 Total revenue bonds ​ $ 25,598 ​ $ 25,380 ​ $ 25,442 ​ $ 24,844 ​ ​ 4. LOANS AND ALLOWANCE FOR CREDIT LOSSES We adopted the current expected credit loss accounting guidance, CECL, and all related amendments as of January 1, 2022. Under CECL, disclosures are presented on the amortized cost basis. Unless specifically noted otherwise, December 31, 2025, 2024, and 2023 disclosures are prepared on the amortized cost basis. Accrued interest receivable on loans of $ 7.0 million and $ 6.1 million at December 31, 2025, and December 31, 2024, respectively is not included in the loans included in the table below but is included in other assets on the Company’s balance sheet. The majority of the disclosures in this footnote are prepared at the class level which combines certain related call report code classification. The final table in this section separates a roll forward of the Allowance for Credit Losses at the portfolio segment level. ​ 90 Table of Contents The following table presents loans by class as of December 31, 2025, and December 31, 2024 (dollars in thousands). ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, ​ ​ ​ ​ 2025 ​ ​ ​ 2024 Real estate: ​ ​ ​ ​ ​ ​ Residential real estate ​ $ 358,454 ​ $ 381,438 Commercial real estate ​ ​ 1,393,183 ​ ​ 1,360,374 Other construction/land ​ ​ 14,497 ​ ​ 5,458 Farmland ​ ​ 68,157 ​ ​ 77,388 Total real estate ​ ​ 1,834,291 ​ ​ 1,824,658 Other commercial ​ ​ 191,500 ​ ​ 177,013 Mortgage warehouse lines ​ ​ 518,333 ​ ​ 326,400 Consumer loans ​ ​ 2,756 ​ ​ 3,270 Subtotal ​ ​ 2,546,880 ​ ​ 2,331,341 Plus net deferred loan (fees) cost ​ ​ ( 35 ) ​ ​ 93 Allowance for credit losses on loans ​ ​ ( 21,480 ) ​ ​ ( 24,830 ) Net loans ​ $ 2,525,365 ​ $ 2,306,604 ​ The following tables present the amortized cost basis of nonaccrual loans, according to loan class, with and without individually evaluated reserves as of December 31, 2025 and 2024 (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2025 ​ ​ Nonaccrual Loans ​ ​ ​ ​ ​ ​ ​ With no allowance for credit loss ​ ​ ​ With an allowance for credit loss ​ Total ​ Loans Past Due 90+ Accruing Real estate: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Residential real estate ​ $ 210 ​ $ — ​ $ 210 ​ $ — Farmland ​ ​ — ​ ​ 1,717 ​ ​ 1,717 ​ ​ — Total real estate ​ ​ 210 ​ ​ 1,717 ​ ​ 1,927 ​ ​ — Other commercial ​ ​ 11,304 ​ ​ — ​ ​ 11,304 ​ ​ — Total ​ $ 11,514 ​ $ 1,717 ​ $ 13,231 ​ $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2024 ​ ​ Nonaccrual Loans ​ ​ ​ ​ ​ ​ ​ With no allowance for credit loss ​ ​ ​ With an allowance for credit loss ​ Total ​ Loans Past Due 90+ Accruing Real estate: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Residential real estate ​ $ 23 ​ $ — ​ $ 23 ​ $ — Farmland ​ ​ 5,105 ​ ​ — ​ ​ 5,105 ​ ​ — Total real estate ​ ​ 5,128 ​ ​ — ​ ​ 5,128 ​ ​ — Other commercial ​ ​ — ​ ​ 14,540 ​ ​ 14,540 ​ ​ — Total ​ $ 5,128 ​ $ 14,540 ​ $ 19,668 ​ $ — ​ The Company did not recognize any interest on nonaccrual loans during 2025, 2024, or 2023 and would have recognized an additional $ 0.9 million, $ 0.9 million, and $ 0.1 million in interest income on nonaccrual loans for the same periods, respectively, had those loans not been designated as nonaccrual. 91 Table of Contents During 2025, there were no significant changes to collateral which secures the collateral-dependent loans, whether due to general deterioration or other reasons.

When principal forgiveness is provided, the amount of forgiveness is charged-off against the allowance for credit losses. In certain cases, the Company provides multiple types of concessions on one loan. Typically, one type of concession, such as a term extension, is granted initially. If the borrower continues to experience financial difficulty, another concession, such as principal forgiveness, may be granted. For the loans included in the “combination” columns below, multiple types of modifications have been made on the same loan within the current reporting period. The combination is at least two of the following: principal forgiveness, rate reductions, payment deferral, and/or term extension. ​ ​ 93 Table of Contents The following table presents the amortized cost basis of loans at December 31, 2025, that were both experiencing financial difficulty and modified during the years ended December 31, 2025 and 2024, by class and by type of modification. The percentage of the amortized cost basis of loans that were modified to borrowers in financial distress as compared to the amortized cost basis of each class of financing receivable is also presented below (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2025 ​ ​ ​ ​ Principal Forgiveness ​ ​ ​ Payment Delay ​ Term Extension ​ Combination Term Extension Interest Rate Reduction ​ Total Class of Financing Receivable Real estate: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial real estate ​ $ — ​ $ 14,146 ​ $ 83 ​ ​ — ​ ​ 1.02 % Total real estate ​ ​ — ​ ​ 14,146 ​ ​ 83 ​ ​ — ​ ​ 0.78 % Other commercial ​ ​ — ​ ​ — ​ ​ 2,961 ​ ​ 214 ​ ​ 1.65 % Total ​ $ — ​ $ 14,146 ​ $ 3,044 ​ $ 214 ​ ​ 0.68 % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2024 ​ ​ ​ ​ Principal Forgiveness ​ ​ ​ Payment Delay ​ Term Extension ​ Combination Term Extension Interest Rate Reduction ​ Total Class of Financing Receivable Real estate: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial real estate ​ ​ — ​ ​ 77 ​ ​ — ​ ​ — ​ ​ 0.01 % Other construction/land ​ ​ — ​ ​ — ​ ​ 219 ​ ​ — ​ ​ 4.00 % Farmland ​ ​ — ​ ​ — ​ ​ 293 ​ ​ — ​ ​ 0.38 % Total real estate ​ ​ — ​ ​ 77 ​ ​ 512 ​ ​ — ​ ​ 0.03 % Other commercial ​ ​ — ​ ​ — ​ ​ 78 ​ ​ — ​ ​ 0.04 % Total ​ $ — ​ $ 77 ​ $ 590 ​ $ — ​ ​ 0.03 % ​ ​ The following table presents the financial effect of the loan modifications presented above to borrowers experiencing financial difficulty for the year ended December 31, 2025 and 2024: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2025 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Principal Forgiveness ​ ​ ​ ​ Weighted-Average Interest Rate Reduction ​ ​ Weighted-Average Term Extension (years) Real estate: ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial real estate ​ $ — ​ ​ — ​ ​ 2.00 Other commercial ​ $ — ​ ​ 0.30 % ​ ​ 1.67 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2024 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Principal Forgiveness ​ ​ ​ ​ Weighted-Average Interest Rate Reduction ​ ​ Weighted-Average Term Extension (years) Real estate: ​ ​ ​ ​ ​ ​ ​ ​ ​ Other construction/land ​ $ — ​ ​ — ​ ​ 3.00 Farmland ​ $ — ​ ​ — ​ ​ 10.00 Other commercial ​ $ — ​ ​ — ​ ​ 2.92 ​ 94 Table of Contents During the years ending December 31, 2025, and 2024, there were no payment defaults, within a twelve-month period of the modification date on loans identified as modifications made to borrowers experiencing financial difficulty. For purposes of this disclosure the Company defines a payment default as 90 days past due. The company had $ 0.1 million in additional funds committed on loans which have been modified to borrowers experiencing financial difficulty as of both December 31, 2025, and December 31, 2024. In estimating the allowance for credit losses, the Company considers the performance of accruing loans which have been identified as modifications made to borrower’s experiencing financial difficulty, in the same way it considers the performance of other collectively evaluated accruing loans. Loan modifications made to borrowers experiencing financial difficulty which have been placed on nonaccrual status are subject to an individual reserve evaluation. Credit Quality The Company monitors the credit quality of loans on a continuous basis using the regulatory and accounting classifications of pass, special mention, and substandard to characterize and qualify the associated credit risk. Loans classified as “loss” are immediately charged-off. The Company uses the following definitions of risk classifications: Pass – Loans listed as pass include larger non-homogeneous loans not meeting the risk rating definitions below and smaller, homogeneous loans not assessed on an individual basis. Special Mention – Loans classified as special mention have the potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date. Substandard – Loans classified as substandard are those loans with clear and well-defined weaknesses such as a highly leveraged position, unfavorable financial operating results and/or trends, or uncertain repayment sources or poor financial condition, which may jeopardize ultimate recoverability of the debt. ​ 95 Table of Contents The following tables present the amortized cost of loans by credit quality classification in addition to loan vintage as of December 31, 2025, and 2024 (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2025 ​ ​ Term Loans Amortized Cost Basis by Origination Year ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 2025 ​ ​ 2024 ​ ​ 2023 ​ ​ 2022 ​ ​ 2021 ​ ​ Prior ​ Revolving Loans Amortized Cost ​ Revolving Loans Converted to Term Loans ​ Total Loans Residential real estate ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Pass ​ $ 1,144 ​ $ -

PCD loans are loans acquired or purchased, which as of acquisition, had evidence of more than insignificant credit deterioration since origination. Due to the immaterial balance in the Company’s PCI loans at the CECL implementation date, management elected not to transition these loans into the PCD designation. As of December 31, 2025, the Company had no loans categorized as PCD. The model used for calculating the Company’s ACL is reviewed and revised periodically, most recently a full review with modifications in the third quarter of 2024, with a partial review and minimal modifications completed in the third quarter of 2025. In the most recent full review, the Company changed to a Multi-Factor Regression Model from a Single-Factor Regression Model used in previous periods. Additionally, legacy peer groups were expanded to include California banks with an asset size between $ 1.5 billion to $ 10 billion. The Company’s ACL is calculated quarterly, with any difference in the calculated ACL and the recorded ACL adjusted through an entry to the provision (benefit) for credit losses. For purposes of estimating the Company’s ACL, Management generally evaluates collectively evaluated loans by call code in order to group loans with similar risk characteristics together; however, Management has grouped loans in selected call codes together in determining portfolio segments, due to similar risk characteristics and reserve methodologies used for certain call code classifications. The DCF quantitative reserve methodology incorporates the consideration of probability of default (“PD”) and loss given default (“LGD”) estimates to estimate periodic losses. The PD estimates are derived through the application of reasonable and supportable economic forecasts to call code specific regression models, derived from the consideration of historical bank-specific and peer loss-rate data. The loss-rate data has been regressed against benchmark economic indicators, for which reasonable and supportable forecasts exist, in the development of the call-code specific regression models. Regression models are updated periodically, in order to pull in more recent loss-rate data. Reasonable and supportable forecasts of the selected economic metric are then input into the regression model to calculate an expected default rate. The expected default rates are then applied to expected monthly loan balances estimated through the consideration of contractual repayment terms and expected prepayments. The Company utilizes a four-quarter forecast period, after which the expected default rates revert to the historical average for each call code, over a four-quarter reversion period, on a straight-line basis. The prepayment assumptions applied to expected cash flow over the contractual life of the loans are estimated based on historical, bank-specific experience, peer data, and the consideration of current and expected conditions and circumstances including the level of interest rates. Management may update prepayment assumptions when changing conditions impact Management’s estimate or additional historical data indicates a reevaluation is warranted. LGD utilized in the DCF is derived from the application of the Frye-Jacobs theory, which relates LGD to PD based on historical peer data, as calculated by a third-party. Economic forecasts are considered over a four-quarter forecast period, with reversion to mean occurring on a straight-line basis over four quarters. The call code multiple factor regression models utilized as of December 31, 2025, for Residential Real Estate loans relied upon reasonable and supportable forecasts of the National Unemployment Rate and House Price Index (HPI). The call code multiple factor regression models utilized as of December 31, 2025, for Commercial Real Estate and Other Construction loans relied upon reasonable and supportable forecasts of the National Unemployment Rate and Gross Domestic Product (GDP). Management selected the National Unemployment Rate, HPI, and GDP as the drivers of quantitative portion of collectively evaluated reserves on loan classes reliant upon the DCF methodology, primarily as a result of high correlation coefficients identified in regression modeling, the availability of forecasts including the quarterly Federal Open Market Committee (FOMC) forecast and given the widespread familiarity of stakeholders with these economic metrics. The quantitative reserves for Farmland, Agricultural Production, and Consumer loans are calculated using a Remaining Life methodology where the Company’s average historical loss-rates are applied to expected loan balances over an estimated remaining life of loans in calculation of the quantitative portion of collectively evaluated loans in these classes. The estimated remaining life is calculated using historical peer data. For the Farmland, Agricultural Production and Consumer classes of loans, reasonable and supportable forecasts of the National Unemployment Rate, real GDP and the housing price index are considered through estimation of qualitative reserves. Management recognizes there are additional factors impacting risk of loss in the loan portfolio beyond what is captured in the quantitative portion of reserves on collectively evaluated loans. As current and expected conditions 98 Table of Contents may vary compared with conditions over the historical lookback period, which is utilized in the calculation of quantitative reserves, Management considers whether additional or reduced reserve levels on collectively evaluated loans may be warranted given the consideration of a variety of qualitative factors. Several of the following qualitative factors (“Q-factors”) considered by Management reflects the legacy regulatory guidance on Q-factors, whereas several others represent factors unique to the Company or unique to the current time period. ● Changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off, and recovery practices ● Changes in international, regional, and local economic and business conditions, and developments that affect the collectability of the portfolio, as reflected in forecasts of the Housing Price Index, Real GDP, and the National Unemployment Rate (Farmland & Agricultural Production and Consumer segments only) ● Changes in the nature and volume of the loan portfolio ● Changes in the experience, ability, and depth of lending Management and other relevant staff ● Changes in the volume and severity of past due, nonaccruals loans, and adversely classified loans, as reflected in changes of the relative level of loans classified as substandard and special mention ● Changes in the quality of the Company’s loan review processes ● Changes in the value of underlying collateral for loans not identified as collateral-dependent ● Changes in loan categorization concentrations ● Other external factors, which include the influence of peer data on estimated quantitative reserves, residual COVID-19 related risk, expected impact of current and expected inflationary environment, reliance on the National Unemployment rate as opposed to the California unemployment rate in the calculation of quantitative reserves, the expected impact of current and expected geo-political conditions The qualitative portion of the Company’s reserves on collectively evaluated loans are calculated using a combination of numeric frameworks and Management judgment to determine risk categorizations in each of the Q-factors presented above. The amount of qualitative reserves is also contingent upon the historical peer, life-of-loan-equivalent, loss-rate ranges, and the relative weighting of Q-factors according to Management’s judgment. Although collectively evaluated reserves are generally calculated separately at the call code or loan class level, Management has grouped loan classes with similar risk characteristics into the following portfolio segments: ● 1-4 Family Real Estate ● Commercial Real Estate ● Farmland & Agricultural Production ● Commercial & Industrial ● Mortgage Warehouse ● Consumer 99 Table of Contents The following table presents the activity in the allowance for credit losses by portfolio segment for the year ended December 31, 2025 and 2024 (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 1-4 Family Real Estate ​ Commercial Real Estate ​ ​ ​ Farmland & Agricultural Production ​ ​ ​ Commercial & Industrial ​ Mortgage Warehouse ​ ​ ​ Consumer (1) ​ ​ ​ Total Allowance for credit losses: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Balance, December 31, 2022 ​ $ 3,251 ​ $ 17,732 ​ $ 458 ​ $ 1,233 ​ $ 72 ​ $ 314 ​ $ 23,060 Charge-offs ​ ​ ( 30 ) ​ ​ ( 2,266 ) ​ ​ ( 1,277 ) ​ ​ ( 1,320 ) ​ ​ — ​ ​ ( 1,728 ) ​ ​ ( 6,621 ) Recoveries ​ ​ 205 ​ ​ 17 ​ ​ 1,370 ​ ​ 425 ​ ​ — ​ ​ 986 ​ ​ 3,003 Provision for credit losses ​ ​ ( 699 ) ​ ​ 3,071 ​ ​ 35 ​ ​ 810 ​ ​ 102 ​ ​ 739 ​ ​ 4,058 Balance, December 31, 2023 ​ $ 2,727 ​ $ 18,554 ​ $ 586 ​ $ 1,148 ​ $ 174 ​ $ 311 ​ $ 23,500 Charge-offs ​ ​ — ​ ​ ( 2,437 ) ​ ​ ( 411 ) ​ ​ ( 528 ) ​ ​ — ​ ​ ( 1,484 ) ​ ​ ( 4,860 ) Recoveries ​ ​ 60 ​ ​ — ​ ​ — ​ ​ 655 ​ ​ — ​ ​ 882 ​ ​ 1,597 Provision for credit losses ​ ​ ( 979 ) ​ ​ 1,026 ​ ​ 3,652 ​ ​ 7 ​ ​ 224 ​ ​ 663 ​ ​ 4,593 Balance, December 31, 2024 ​ $ 1,808 ​ $ 17,143 ​ $ 3,827 ​ $ 1,282 ​ $ 398 ​ $ 372 ​ $ 24,830 Charge-offs ​ ​ — ​ ​ ( 1,421 ) ​ ​ ( 7,527 ) ​ ​ ( 495 ) ​ ​ — ​ ​ ( 907 ) ​ ​ ( 10,350 ) Recoveries ​ ​ — ​ ​ — ​ ​ 410 ​ ​ 42 ​ ​ — ​ ​ 453 ​ ​ 905 Provision for credit losses ​ ​ ( 397 ) ​ ​ 928 ​ ​ 4,436 ​ ​ 667 ​ ​ 267 ​ ​ 194 ​ ​ 6,095 Balance, December 31, 2025 ​ $ 1,411 ​ $ 16,650 ​ $ 1,146 ​ $ 1,496 ​ $ 665 ​ $ 112 ​ $ 21,480 (1) Includes overdraft charge-offs of $ 0.9 million and $ 1.4 million for the years ended December 31, 2025 and 2024, respectively, and overdraft recoveries of $ 0.4 million and $ 0.9 million for the years ended December 31, 2025 and 2024, respectively. ​ 5.

OPERATING LEASES The Company leases space under non-cancelable operating leases for 30 branch locations, three off-site ATM locations, one administrative building, and two loan production offices. Many of our leases include both lease (e.g., fixed payments including rent, taxes, and insurance costs) and non-lease components (e.g., common-area or other maintenance costs). Payments for taxes and insurance as well as non-lease components are not included in the accounting of the lease component but are separately accounted for in occupancy expense. The Company recognized lease expense of $ 4.6 million for the year ended December 31, 2025, $ 4.5 million for the year ended December 31, 2024, and $ 2.3 million for the year ended December 31, 2023. Most leases include one or more renewal options available to exercise. The exercise of lease renewal options is typically at the Company’s sole discretion; therefore, the majority of renewals to extend the lease terms are not included in our right-of-use assets and lease liabilities as they are not reasonably certain of exercise. We regularly evaluate the renewal options and when they are reasonably 100 Table of Contents certain of exercise, we include the renewal period in our lease term. As most of our leases do not provide an implicit rate, we used our incremental borrowing rate in determining the present value of the lease payments. There were no leveraged leases or lease transactions with related parties during the years ending December 31, 2025 and 2024. In December 2023, the Company completed a sale and leaseback transaction on 11 branch buildings with a book value of $ 4.8 million, for a gain on sale of $ 15.3 million. In the first quarter of 2024 the Company completed another sale leaseback transaction of two additional branch buildings with a book value of $ 0.7 million, for a gain on sale of $ 3.8 million. These branch buildings were subsequently leased back to the Company and are reflected in the tables in this footnote. The 2023 sale and leaseback transaction resulted in additions to the Company’s right of use asset and operating lease liability of $ 18.0 million and $ 13.8 million, respectively at the year ended December 31, 2023. The 2024 sale and leaseback transaction resulted in additions to the Company’s right of use asset and operating lease liability of $ 3.9 million and $ 3.1 million, respectively at the year ended December 31, 2024. Each of the new leases have an average life of 18 years . At December 31, 2025, the Company’s right-of-use assets and operating lease liabilities were $ 26.5 million and $ 23.1 million, respectively. The weighted average remaining lease term for the lease liabilities was 12.8 years, and the weighted average discount rate of remaining payments was 8.7 percent. At December 31, 2024, the Company’s right-of-use assets and operating lease liabilities were $ 27.8 million and $ 23.7 million, respectively. The weighted average remaining lease term for the lease liabilities was 13.5 years, and the weighted average discount rate of remaining payments was 8.7 percent for the year ended December 31, 2024. Lease liabilities from new right-of-use assets obtained during the year ending December 31, 2025, and December 31, 2024, were $ 1.4 million and $ 4.7 million, respectively. There was $ 0.2 million in variable lease costs for each of the years ending December 31, 2025, 2024, and 2023. Cash paid on operating leases was $ 4.0 million for the year ended December 31, 2025, and $ 4.0 million for the year ended December 31, 2024. Future undiscounted lease payments for operating leases with initial terms of one year or more as of December 31, 2025, are as follows (dollars in thousands): ​ ​ ​ ​ ​ Year Ending December 31, ​ ​ ​ 2026 ​ ​ ​ $ 3,913 2027 ​ ​ 3,731 2028 ​ ​ 3,097 2029 ​ ​ 2,539 2030 ​ ​ 2,383 Thereafter ​ ​ 25,043 Total undiscounted lease payments ​ $ 40,706 Less: imputed interest ​ ​ ( 17,637 ) Net lease liabilities ​ $ 23,069 ​ The Company generally has options to renew its facilities leases after the initial leases expire. The renewal options range from one to ten years . ​ 7. GOODWILL AND INTANGIBLE ASSETS Goodwill The balance of goodwill at the years beginning and ended December 31, 2025, 2024, and 2023 was $ 27.4 million. There was no acquired goodwill or impairment for the years ended December 31, 2025, 2024, and 2023. The Company performed a quantitative impairment assessment as of October 1, 2025, using a market approach. Based on the results of the Company’s goodwill impairment assessment, the Company determined that the fair value of its reporting unit, which was at the consolidated level, exceeded the carrying value. Therefore, goodwill was not 101 Table of Contents impaired as of December 31, 2025, and there was no impairment charges related to the Company’s goodwill recorded during the year ended December 31, 2025. Acquired Intangible Assets Acquired intangible assets were as follows at year-end (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Years Ended December 31, ​ ​ 2025 ​ 2024 ​ ​ ​ ​ Gross Carrying Amount ​ ​ ​ Accumulated Amortization ​ ​ ​ Gross Carrying Amount ​ ​ ​ Accumulated Amortization Core deposit intangibles ​ $ 5,181 ​ $ 5,129 ​ $ 5,181 ​ $ 4,563 ​ Aggregate amortization expense was $ 0.6 million, $ 0.8 million, and $ 0.9 million for 2025, 2024, and 2023.

Under this method, the investments are initially recorded at their historical cost. Dividends received from these investments are recorded in Other Income in the Income Statement. Management analyzes these investments annually for potential impairment. The Company holds certain equity investments that are not readily marketable securities and thus are classified as “other assets” on the Company’s balance sheet. These include investments in Pacific Coast Bankers Bancshares, California Economic Development Lending Initiative, and the Federal Home Loan Bank (“FHLB”). The largest of these is the Company’s $ 14.7 million investment in FHLB stock, carried at cost. Quarterly, the FHLB evaluates and adjusts the Company’s minimum stock requirement based on the Company’s borrowing activity and membership 102 Table of Contents requirements. Any stock deemed in excess is automatically repurchased by the FHLB at cost. The only equity investment noted above that is carried at Fair Value is the Company’s investment in PCBB stock. ​ 9.

There were no outstanding short-term borrowings at December 31, 2024. Each FHLB advance is payable at its maturity date, with a prepayment penalty for fixed rate advances. The advances were collateralized by $ 1.3 billion of first mortgage loans under a blanket lien arrangement at year end 2025. Based on this collateral and the Company’s holdings of FHLB stock, the Company was eligible to borrow up to the total of $ 629.5 million at year-end 2025, with a remaining borrowing capacity of $ 849.7 million if sufficient additional collateral was pledged. The carrying value of the securities pledged to collateralize repurchase agreements was $ 168.6 million at December 31, 2025, and $ 169.5 million at December 31, 2024. The Company had borrowings of $ 210 million at December 31, 2025, and no borrowings at year end 2024 from the FRB. The Company was eligible to borrow up to $ 254.9 million from FRB at year end 2025, which was collateralized by $ 129.9 million in first mortgage loans under a blanket lien arrangement. The Company had lines of credit with its correspondent banks which, in the aggregate, amounted to $ 250.8 million unsecured and $ 25.0 million secured at December 31, 2025, and $ 479.8 million unsecured and $ 25.0 million secured at December 31, 2024, at fixed interest rates which vary with market conditions. There were outstanding overnight balances of $ 210 million under these lines of credit at December 31, 2025, and no outstanding overnight balances under these lines of credit at December 31, 2024. ​ 11.

The Company adopted ASU 2023-09 “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” on a prospective basis beginning with the year ended December 31, 2025. A reconciliation of income tax expense at the U.S. federal statutory rate ( 21 % in 2025) to the Company’s actual income tax expense for the year ended December 31, 2025, is shown below: ​ ​ ​ ​ ​ ​ ​ Year Ended December 31, 2025 ​ Amount ​ Percent Income tax expense at federal statutory rate $ 11,832 ​ 21.00 % State and local income tax, net of federal tax effect (1) ​ 4,119 ​ 7.31 % Tax credits ​ ​ ​ ​ Affordable housing tax credits, net of amortization and other income tax benefit ​ ( 505 ) ​ ( 0.90 )% Nontaxable or nondeductible items ​ ​ ​ ​ Tax-exempt interest, net of disallowance ​ ( 854 ) ​ ( 1.52 )% Bank-owned life insurance ​ ( 724 ) ​ ( 1.28 )% Other ​ ( 8 ) ​ ( 0.01 )% Other adjustments ​ 156 ​ 0.28 % ​ $ 14,016 ​ 24.88 % (1) State taxes in California made up the majority ( greater than 50 percent ) of the tax effect in this category. 107 Table of Contents The following table is a reconciliation of the statutory U.S. corporate federal income tax rate to the Company’s effective tax rate for 2024 and 2023 in accordance with the guidance prior to the adoption of ASU 2023-09: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended December 31, ​ ​ ​ ​ 2024 ​ ​ ​ 2023 Income tax expense at federal statutory rate ​ $ 11,312 ​ $ 9,758 Increase (decrease) resulting from: ​ ​ ​ ​ ​ ​ State franchise tax expense, net of federal tax effect ​ ​ 3,867 ​ ​ 3,698 Tax exempt municipal income ​ ​ ( 1,416 ) ​ ​ ( 2,291 ) Nondeductible interest expense ​ ​ 585 ​ ​ ​ Affordable housing tax credits ​ ​ ( 208 ) ​ ​ 16 Excess tax (benefit) expense of stock-based compensation ​ ​ ( 329 ) ​ ​ 22 Cash surrender value - life insurance ​ ​ ( 594 ) ​ ​ ( 371 ) Other ​ ​ 91 ​ ​ 788 Total ​ $ 13,308 ​ $ 11,620 Effective tax rate ​ ​ 24.71 % ​ ​ 25.01 % ​ Income taxes paid were as follows (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ 2025 Federal ​ $ 5,825 California ​ ​ 4,650 Other state and local ​ ​ 7 Total ​ $ 10,482 ​ The Company is subject to federal income tax and income tax of various states. Our federal income tax returns for the years ended December 31, 2022, 2023, and 2024 are open to audit by the federal authorities and our California state tax returns for the years ended December 31, 2021, 2022, 2023, and 2024 are open to audit by the state authorities. At December 31, 2025, the Company has federal net operating loss carry forwards of approximately $ 2.8 million which expire at various dates from 2031 to 2036. The Company also had California Franchise tax net operating loss carry forwards of approximately $ 5.4 million which expire at various dates from 2034 to 2041. Net operating loss carry forwards available from acquisitions are substantially limited by Section 382 of the Internal Revenue Code and benefits not expected to be realized due to the limitation have been excluded from the deferred tax asset and net operating loss carry forward amounts noted above. There were no recorded interest or penalties related to uncertain tax positions as part of income tax for the years ended December 31, 2025, 2024, and 2023, respectively. We do not expect the total amount of unrecognized tax benefits to significantly increase or decrease within the next twelve months. ​ 14. COMMITMENTS AND CONTINGENCIES Letter of Credit The Company holds two letters of credit with the Federal Home Loan Bank of San Francisco totaling $ 127.9 million. A $ 125.0 million letter of credit is pledged to secure public deposits at December 31, 2025 and a $ 2.9 million standby letter of credit was obtained on behalf of one of our customers to guarantee financial performance. Should the standby letter of credit be drawn upon, the customer would reimburse the Company from an existing line of credit. 108 Table of Contents Financial Instruments with Off-Balance-Sheet Risk The Company is a party to financial instruments with off-balance-sheet risk in the normal course of business. These financial instruments consist of commitments to extend credit and standby letters of credit. These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated balance sheet. The Company’s exposure to credit loss in the event of nonperformance by the other party for commitments to extend credit and letters of credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and letters of credit as it does for loans included on the balance sheet. The following financial instruments represent off-balance-sheet credit risk (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, ​ ​ ​ ​ 2025 ​ ​ ​ 2024 Fixed-rate commitments to extend credit ​ $ 75,928 ​ $ 80,127 Variable-rate commitments to extend credit ​ $ 471,496 ​ $ 556,320 Standby letters of credit ​ $ 5,708 ​ $ 5,046 ​ Commitments to extend credit consist primarily of the unused or unfunded portions of the following: home equity lines of credit; commercial real estate construction loans, where disbursements are made over the course of construction; commercial revolving lines of credit; mortgage warehouse lines of credit; unsecured personal lines of credit; and formalized deposit account overdraft lines. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Commitments to extend credit are made at both fixed and variable rates of interest as stated in the table above. Standby letters of credit are generally unsecured and are issued by the Company to guarantee the performance of a customer to a third party, while commercial letters of credit represent the Company’s commitment to pay a third party on behalf of a customer upon fulfillment of contractual requirements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loans to customers. Concentration in Real Estate Lending At December 31, 2025, in management’s judgment, the Company had a concentration of loans secured by real estate. At that date, approximately 72 % of the Company’s loans were real estate related. Balances secured by commercial buildings and construction and development loans represented 76 % of all real estate loans, while loans secured by non-construction residential properties accounted for 20 %, and loans secured by farmland were 4 % of real estate loans. Although management believes the loans within these concentrations have no more than the normal risk of collectability, a decline in the performance of the economy in general or a decline in real estate values in the Company’s primary market areas, in particular, could have an adverse impact on collectability. Concentration by Geographic Location The Company extends commercial, real estate mortgage, real estate construction, and consumer loans to customers primarily in the South Central San Joaquin Valley of California, specifically Tulare, Fresno, Kern, Kings, and Madera counties; and the Coastal counties of San Luis Obispo, Ventura, and Santa Barbara. The ability of a substantial portion of the Company’s customers to honor their contracts is dependent on the economy in these areas. Although the Company’s loan portfolio is diversified, there is a relationship in those regions between the local agricultural economy and the economic performance of loans made to non-agricultural customers. Legal Matters In the ordinary course of our business, the Company is subject to legal proceedings and claims which we believe are incidental to the operation of our business. The outcome of such legal actions and the timing of ultimate resolution 109 Table of Contents are inherently difficult to predict. Given the nature, scope, and complexity of the extensive legal and regulatory landscape applicable to banking (including laws and regulations governing consumer protection, fair lending, privacy, information security, and anti-money laundering and anti-terrorism laws), we like all banking organizations, are subject to heightened legal and regulatory compliance and litigation risk. The Company will establish litigation and legal reserves, where appropriate, in accordance with FASB guidance over loss contingencies (ASC 450). Upon consultation with legal counsel and based on information currently available to us, management does not expect the amount of any resulting liability, in addition to amounts already accrued and taking into consideration insurance which may be applicable, to have a material adverse effect on the consolidated financial position or results of operations of the Company. 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 or regulatory matters currently pending or threatened could have a material adverse effect on our liquidity, consolidated financial position, and/or results of operations. ​ 15. SHAREHOLDERS’ EQUITY Share Repurchase Plan At December 31, 2025, the Company had a 2025 Share Repurchase Plan with an expiration date of October 31, 2026. This share repurchase plan replaced the 2024 Share Repurchase Plan which expired on October 31, 2025. During the year ended December 31, 2025, the Company repurchased 222,039 shares under the 2025 Share Repurchase Plan and 802,753 shares under the 2024 Share Repurchase Plan. The total number of shares available for repurchase at December 31, 2025, was 777,961 . Repurchases are generally made in the open market at market prices. Earnings Per Share A reconciliation of the numerators and denominators of the basic and diluted earnings per share computations is as follows (dollars in thousands, except per share data): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the Years Ended December 31, ​ ​ ​ ​ 2025 ​ ​ ​ 2024 ​ ​ ​ 2023 Basic Earnings Per Share ​ ​ ​ ​ ​ ​ ​ ​ ​ Net income ​ $ 42,327 ​ $ 40,560 ​ $ 34,844 Weighted average shares outstanding ​ ​ 13,496,560 ​ ​ 14,284,401 ​ ​ 14,706,141 Basic earnings per share ​ $ 3.14 ​ $ 2.84 ​ $ 2.37 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Diluted Earnings Per Share ​ ​ ​ ​ ​ ​ ​ ​ ​ Net income ​ $ 42,327 ​ $ 40,560 ​ $ 34,844 Weighted average shares outstanding ​ ​ 13,496,560 ​ ​ 14,284,401 ​ ​ 14,706,141 Effect of dilutive equity awards ​ ​ 96,559 ​ ​ 111,620 ​ ​ 31,729 Weighted average shares outstanding ​ ​ 13,593,119 ​ ​ 14,396,021 ​ ​ 14,737,870 Diluted earnings per share ​ $ 3.11 ​ $ 2.82 ​ $ 2.36 ​ Stock options and unvested restricted stock awards for 250,391 and 298,986 shares of common stock were not considered in computing diluted earnings per common share for 2024 and 2023, respectively, because they were antidilutive. There were no antidilutive shares of common stock in 2025. Stock Options On March 17, 2023, the Company’s Board of Directors approved and adopted the 2023 Equity Compensation Plan (the “2023 Plan”), which became effective May 24, 2023, the date approved by the Company’s shareholders. The 2023 Plan replaced the Company’s 2017 Stock Incentive Plan (the “2017 Plan”). Options to purchase 139,400 shares granted under the 2017 Plan and options to purchase 50,000 shares that were granted under the 2007 Plan were still 110 Table of Contents outstanding as of December 31, 2025, and remain unaffected by that plan’s expiration. The 2023 Plan provides for the issuance of several types of equity awards, including options, stock appreciation rights, restricted stock awards, restricted share units, performance share awards, dividend equivalents, or any combination thereof. Such awards may be granted to officers and employees as well as non-employee directors, which awards may be granted on such terms and conditions as are established by the Board of Directors or the Compensation Committee in its discretion. The total number of shares of the Company’s authorized but unissued stock reserved for issuance pursuant to awards under the 2023 Plan was initially 360,000 shares, and the number remaining available for grant as of December 31, 2025, was 267,316 . All options granted under the 2023 , 2017 , and 2007 Plans have been or will be granted at an exercise price of not less than 100 % of the fair market value of the stock on the date of grant, exercisable in installments as provided in individual stock option agreements. In the event of a “Change in Control” as defined in the Plans, all outstanding options shall become exercisable in full (subject to certain notification requirements) and shall terminate if not exercised within a specified period of time unless such options are assumed by the successor corporation or substitute options are granted. Options also terminate in the event an optionee ceases to be employed by or to serve as a director of the Company or its subsidiaries, and the vested portion thereof must be exercised within a specified period after such cessation of employment or service.

During the year ended December 31, 2024, $ 1.5 million in cash was received from the exercise of 78,249 shares with a related tax benefit of $ 0.2 million. No shares were exercised during the year ended December 31, 2023. The Company used the Black-Scholes model to value stock options. In accordance with U.S. GAAP, charges $ 0.03 million and $ 0.1 million are reflected in the Company’s income statements for the years ended December 31, 2024 and 2023, respectively, as pre-tax compensation and directors’ expense related to stock options. There was an inconsequential expense recorded for the year ended December 31, 2025, and all outstanding stock options are now fully vested and therefore fully expensed. The related tax benefit of these options was inconsequential for the years ended December 31, 2025 and 2024. There is no unamortized compensation expense associated with unvested stock options outstanding at December 31, 2025, and all stock options are fully amortized as of February 2025. 111 Table of Contents Restricted Stock Grants The Company’s restricted stock awards granted under the 2017 Plan and 2023 Plan are non-transferable shares of common stock and are available to be granted to the Company’s employees and directors. The vesting period of restricted stock awards is determined at the time the awards are issued, and different awards may have different vesting terms; provided, however, that no installment of any restricted stock award shall become vested less than one year from the grant date. Restricted stock awards are valued utilizing the fair value of the Company’s stock at the grant date. During the year ending 2025, 93,712 shares were granted to employees and directors of the Company under the 2023 Plan. These awards are expensed on a straight-line basis over the vesting period. Compensation expense related to restricted stock units for the years ended December 31, 2025, 2024, and 2023 was $ 2.2 million, $ 1.9 million, and $ 1.7 million respectively, and the recognized income tax benefit related to this expense was $ 0.8 million, $ 0.6 million, and $ 0.5 million, respectively. As of December 31, 2025, there was $ 2.7 million of unamortized compensation and directors’ cost related to unvested restricted stock awards granted under the 2023 and 2017 plans. That cost is expected to be amortized over a weighted average period of 2.3 years. The total fair value of shares vested during the year ended December 31, 2025, 2024, and 2023 was $ 1.9 million, $ 1.8 million, and $ 1.2 million, respectively.

REGULATORY MATTERS The Company and the Bank are subject to regulatory capital requirements administered by the Board of Governors of the Federal Reserve System and the FDIC. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action. The net unrealized gain or loss on available for sale securities is not included in computing regulatory capital. Management believes as of December 31, 2025, the Company and Bank meet all capital adequacy requirements to which they are subject. Prompt corrective action regulations provide five classifications: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. If adequately capitalized, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited, as is asset growth and expansion, and capital restoration plans are required. At year-end December 31, 2025 and 2024, notification from the FDIC categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the Bank's categorization. The federal banking agencies jointly provide for an optional, simplified measure of capital adequacy known as the community bank leverage ratio framework (CBLR framework), for qualifying community banking organizations, consistent with Section 201 of the Economic Growth, Regulatory Relief, and Consumer Protection Act. Under the final rule, an eligible banking organization can opt out of the CBLR framework and revert back to the risk-weighting framework without restriction. Both the Company and the Bank have continuously remained as qualifying 112 Table of Contents community banking organizations and elected to adopt and measure capital adequacy under the CBLR framework since it became effective in 2020. The CBLR framework removes the requirement for qualifying banking organizations to calculate and report risk-based capital ratios, but rather only requires a Tier 1 to average assets (leverage) ratio. Qualifying banking organizations that elect to use the CBLR framework and that maintain a leverage ratio of greater than required minimums will be considered to have satisfied the generally applicable risk based and leverage capital requirements in the agencies' capital rules (generally applicable rule) and, if applicable, will be considered to have met the well capitalized ratio requirements for purposes of section 38 of the Federal Deposit Insurance Act. Actual and required capital amounts (dollars in thousands) and ratios are presented below at year end. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Actual ​ To Be Well Capitalized Under Prompt Corrective Action Regulations (CBLR Framework) 2025 ​ ​ ​ Capital Amount ​ ​ ​ Ratio ​ ​ ​ Capital Amount ​ ​ ​ Ratio Tier 1 (Core) Capital to average total assets ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Sierra Bancorp and subsidiary ​ $ 396,655 ​ 10.80 % ​ $ 330,546 ​ 9.00 % Bank of the Sierra ​ $ 437,868 ​ 11.94 % ​ $ 330,051 ​ 9.00 % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Actual ​ To Be Well Capitalized Under Prompt Corrective Action Regulations (CBLR Framework) 2024 ​ ​ ​ Capital Amount ​ ​ ​ Ratio ​ ​ ​ Capital Amount ​ ​ ​ Ratio Tier 1 (Core) Capital to average total assets ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Sierra Bancorp and subsidiary ​ $ 398,381 ​ 10.93 % ​ $ 328,036 ​ 9.00 % Bank of the Sierra ​ $ 429,604 ​ 11.80 % ​ $ 327,664 ​ 9.00 % ​ Dividend Restrictions The Company’s ability to pay cash dividends is dependent on dividends paid to it by the Bank and is also limited by state corporation law. California law allows a California corporation to pay dividends if the company’s retained earnings equal at least the amount of the proposed dividend plus any preferred dividend arrears amount. If a California corporation does not have sufficient retained earnings available for the proposed dividend, it may still pay a dividend to its shareholders if immediately after the dividend the value of the company’s assets would equal or exceed the sum of its total liabilities plus any preferred dividend arrears amount. Dividends from the Bank to the Company are restricted under California law to the lesser of the Bank’s retained earnings or the Bank’s net income for the latest three fiscal years, less dividends previously declared during that period, or, with the approval of the Department of Financial Protection and Innovation, to the greater of the retained earnings of the Bank, the net income of the Bank for its last fiscal year, or the net income of the Bank for its current fiscal year. As of December 31, 2025, the maximum amount available for dividend distribution under this restriction was approximately $ 38.8 million. ​ 113 Table of Contents 17. BENEFIT PLANS Salary Continuation Agreements, Directors’ Retirement and Officer Supplemental Life Insurance Plans The Company entered into salary continuation agreements with certain senior officers in 2002 and 2007 and also established retirement plans for certain qualifying members of the Board of Directors at the same time. The plans provide for annual benefits for up to fifteen years after retirement or death. The benefit obligation under these plans is recognized on the consolidated balance sheet in other liabilities and totaled $ 3.9 million and $ 4.1 million for the years ended December 31, 2025 and 2024, and was fully accrued for both years. There was a $ 0.2 million expense accrual recognized under these arrangements for the year ended December 31, 2025, and no expense accrual recorded in 2024. The expense recognized under these arrangements totaled $ 0.3 million for the year ended December 31, 2023. Salary continuation benefits paid to former directors or executives of the Company, or their beneficiaries totaled $ 0.4 million, $ 0.5 million, and $ 0.5 million for the years ended December 31, 2025, 2024, and 2023. Certain officers of the Company have supplemental life insurance policies with death benefits available to the officers’ beneficiaries with an accumulated post-retirement benefit liability of $ 0.8 million and $ 0.9 million for the years ended December 31, 2025 and 2024, respectively. In connection with these plans and other employee benefit plans of the Company, the Company has purchased, or acquired through merger, single premium life insurance policies with cash surrender values totaling $ 56.1 million and $ 41.3 million at December 31, 2025 and 2024. Officer and Director Deferred Compensation Plan The Company has established a non-qualified deferred compensation plan for certain members of the management group and a deferred fee plan for directors for the purpose of providing the opportunity for participants to defer compensation. The Company bears the costs and the liability for the plan’s administration and the changes to income earned on participant deferrals. The related administrative expense was not material for the years ended December 31, 2025, 2024, and 2023; however, the changes to the liability related to income earned on participant deferrals can be significant. The deferred compensation liability totaled $ 13.7 million and $ 12.3 million at December 31, 2025 and 2024, respectively, and is in other liabilities on the Company’s consolidated balance sheet. Although there is no requirement to fund this plan, the Company has purchased life insurance policies with cash surrender values totaling $ 13.2 million and $ 11.8 million at December 31, 2025 and 2024, respectively, which are specific account policies with underlying investments similar to the hypothetical investments elected inside the participant deferred compensation accounts. The purpose of these specific account life insurance policies is to provide an economic offset against changes to the participant liability. 401(k) Savings Plan The 401(k) savings plan (the “Plan”) allows participants to defer, on a pre-tax basis, up to 15 % of their salary (subject to Internal Revenue Service limitations) and accumulate tax-deferred earnings as a retirement fund. The amount of the matching contribution was 80 % for the year ended December 31, 2022, with vesting over a period of five years from the participants’ hire date. Starting in 2024, the Company has adopted a safe-harbor plan and matched 100 % of the first 2% of participants’ 401(k) elective deferral contributions, and 50 % of participants’ 401(k) elective deferral contributions which are over 2% of participants’ pay but are not over 6% of participants’ pay. The matching contribution is discretionary, vests over a period of two years from the participants’ hire date and is subject to the approval of the Board of Directors. The Company contributed $ 1.2 million, $ 1.2 million, and $ 1.3 million to the Plan in the years ended 2025, 2024, and 2023, respectively. ​ 18. NONINTEREST INCOME The major grouping of noninterest revenue on the consolidated income statements includes several specific items: service charges on deposit accounts, gains on the sale of loans, credit card fees, check card fees, the net gain (loss) on sales and calls of investment securities available for sale, and the net increase (decrease) in the cash surrender value of life insurance. 114 Table of Contents Noninterest income also includes one general category of “other income” of which the following are major components (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended December 31, ​ ​ ​ ​ 2025 ​ ​ ​ 2024 ​ ​ ​ 2023 Included in other income: ​ ​ ​ ​ ​ ​ ​ ​ ​ Dividends on equity investments ​ $ 1,335 ​ $ 1,337 ​ $ 1,076 Unrealized losses recognized on equity investments ​ ​ — ​ ​ ( 311 ) ​ ​ ( 291 ) SBA loan fund income ​ ​ 1,225 ​ ​ 1,467 ​ ​ 1,423 Credit card and other loan fees ​ ​ 808 ​ ​ 712 ​ ​ 776 Other ​ ​ 1,057 ​ ​ 325 ​ ​ 1,380 Total other noninterest income ​ $ 4,425 ​ $ 3,530 ​ $ 4,364 ​ ​ 19.

RELATED PARTY TRANSACTIONS During the normal course of business, the Bank may enter into loans with related parties, including executive officers and directors. These loans are made with substantially the same terms, including rates and collateral, as loans to unrelated parties. The following is a summary of the aggregate activity involving related party borrowers (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended December 31, ​ ​ ​ ​ 2025 ​ ​ ​ 2024 ​ ​ ​ 2023 Balance, beginning of year ​ $ 26 ​ $ 82 ​ $ 139 Disbursements ​ ​ — ​ ​ 5 ​ ​ — Amounts repaid ​ ​ ( 21 ) ​ ​ ( 64 ) ​ ​ ( 57 ) Effect of changes in composition of related parties ​ ​ ( 5 ) ​ ​ 3 ​ ​ — Balance, end of year ​ $ — ​ $ 26 ​ $ 82 Undisbursed commitments to related parties ​ $ — ​ $ 3 ​ $ 6 ​ Deposits from related parties held by the Bank at December 31, 2025 and 2024, amounted to $ 4.0 million and $ 6.1 million, respectively. 115 Table of Contents ​ 21. FAIR VALUE Fair value is defined by U.S. GAAP as the exchange price that would be received for an asset or paid to transfer a liability (an 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. U.S. GAAP also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value: ● Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. ● Level 2: Significant observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, and other inputs that are observable or can be corroborated by observable market data. ● Level 3: Significant unobservable inputs that reflect a company’s own assumptions about the factors that market participants would use in pricing an asset or liability. The Company used the following methods and significant assumptions to estimate fair values for each category of financial asset noted below: Securities : The fair values of securities available-for-sale are determined by obtaining quoted prices on nationally recognized securities exchanges, live trading desk pricing from brokerages, or by matrix pricing, which is a mathematical technique used widely in the industry to value debt securities by relying on their relationship to other benchmark quoted securities. In certain circumstances live trading desk pricing from brokerages and third-party internal models are used to value debt securities that we classify as Level 3. Individually evaluated collateral dependent loans : Individually evaluated collateral dependent loans are measured based on the fair value of collateral when foreclosure is probable, or repayment is expected through the sale or operation of collateral and borrower is experiencing financial difficulty. For real estate loans, fair value of the loan’s collateral is determined by third party appraisals, which are then adjusted for the estimated selling and closing costs related to liquidation of the collateral. For this asset class, the actual valuation methods (income, sales comparable, or cost) vary based on the status of the project or property. For example, land is generally based on the sales comparable method while construction is based on the income and/or sales comparable methods. The unobservable inputs may vary depending on the individual assets with no one of the three methods being the predominant approach. The Company reviews the third-party appraisal for appropriateness and adjusts the value downward to consider selling and closing costs, which typically range from 5 % to 10 % of the appraised value. Non-real estate collateral may be valued using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on Management’s historical knowledge, changes in market conditions from the time of the valuation, and Management’s expertise and knowledge of the client and client’s business, resulting in a Level 3 fair value classification. Collateral-dependent loans are evaluated on a quarterly basis and adjusted in accordance with the allowance for credit losses policy. Foreclosed assets : Assets acquired through or instead of loan foreclosure are initially recorded at fair value less costs to sell when acquired or when foreclosure is imminent. Repossessed real estate (known as other real estate owned, or “OREO”) and other foreclosed assets are reported at fair value on a non-recurring basis. Fair values of OREO are based on recent real estate appraisals which are updated no less frequently than annually. These appraisals may use a single valuation approach or a combination of approaches including sales comparison, cost approach, and the income approach. Adjustments are often made in the appraisal process by the appraisers to take into account differences between the comparable sales and income and other available data. Management also incorporates assumptions regarding market trends or other relevant factors and selling and commission costs ranging from 5 % to 10 %. Such adjustments can be significant and typically result in a 116 Table of Contents Level 3 classification of the unobservable inputs for determining fair value. Fair values for any other foreclosed assets are represented by estimated sales processed as determined using reasonably available sources. The valuation technique used for Level 3 non-recurring OREO is primarily the sales comparison approach less estimated selling costs.

DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS Disclosures include estimated fair values for financial instruments for which it is practicable to estimate fair value. These estimates are made as of the respective balance sheet dates based on relevant market data and information about the financial instruments. These estimates do not reflect any premium or discount that could result from offering the Company’s entire holdings of a particular financial instrument for sale at one time, nor do they attempt to estimate the value of anticipated future business related to the instruments. In addition, the tax ramifications related to the realization of unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in any of these estimates. Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding current economic conditions, risk characteristics of various financial instruments and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the fair values presented. The following methods and assumptions were used by the Company to estimate the fair value of its financial instruments at December 31, 2025 and 2024: Cash and cash equivalents and fed funds sold : For cash and cash equivalents and fed funds sold, the carrying amount is estimated to be fair value. 118 Table of Contents Securities : The fair values of investment securities are determined by obtaining quoted prices on nationally recognized securities exchanges, live trading desk pricing from brokerages, or by matrix pricing, which is a mathematical technique used widely in the industry to value debt securities by relying on their relationship to other benchmark quoted securities when quoted prices for specific securities are not readily available. Loans : Fair values of loans are based on the exit price notion set forth by ASU 2016-01 effective January 1, 2018, and estimated using discounted cash flow analyses. The estimation of fair values of loans results in a Level 3 classification as it requires various assumptions and considerable judgement to incorporate factors relevant when selling loans to market participants, such as funding costs, return requirements of likely buyers and performance expectations of the loans given the current market environment and quality of loans. Deposits : Fair values for non-maturity deposits are equal to the amount payable on demand at the reporting date, which is the carrying amount. Fair values for fixed-rate certificates of deposit are estimated using a cash flow analysis, discounted at interest rates being offered at each reporting date by the Bank for certificates with similar remaining maturities. Short-term borrowings: The carrying amounts approximate fair values for federal funds purchased, overnight FHLB advances, borrowings under repurchase agreements, and other short-term borrowings maturing within ninety days of the reporting dates. Fair values of other short-term borrowings are estimated by discounting projected cash flows at the Company’s current incremental borrowing rates for similar types of borrowing arrangements.
