NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1 - Summary of Significant Accounting Policies

Description of Business and Basis of Presentation

TriCo Bancshares (the “Company” or “we”) is a California corporation organized to act as a bank holding company for Tri Counties Bank (the “Bank”). The Company and the Bank are headquartered in Chico, California. The Bank is a California-chartered bank that is engaged in the general commercial banking business in 31 California counties. The consolidated financial statements are prepared in accordance with accounting policies generally accepted in the United States of America and general practices in the banking industry. All adjustments necessary for a fair presentation of these consolidated financial statements have been included and are of a normal and recurring nature. The financial statements include the accounts of the Company. All inter-company accounts and transactions have been eliminated in consolidation.

The Company maintains two capital subsidiary business trusts (collectively, the “Capital Trusts”), both organized by the Company. For financial reporting purposes, the Company’s investments in the Capital Trusts of $1.2 million are accounted for under the equity method and, accordingly, are not consolidated and are included in other assets on the consolidated balance sheets.

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires Management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025 (the “2025 Annual Report”). The Company believes that the disclosures made are adequate to make the information not misleading.

Segment and Significant Group Concentration of Credit Risk

The Company grants agribusiness, commercial, consumer, and residential loans to customers located throughout California. The Company has a diversified loan portfolio within the business segments located in this geographical area. While our Chief Executive Officer, the chief operating decision-maker (CODM), may monitor the revenue streams of the various products and services, operations are managed, financial performance is evaluated, and decisions are generally made on a Company-wide basis. Discrete financial information is not available other than on a Company-wide basis. Accordingly, operations are considered by management to be aggregated in one reportable operating segment.

Geographical Descriptions

For the purpose of describing the geographical location of the Company’s operations, the Company has defined northern California as that area of California north of, and including, Stockton to the east and San Jose to the west; central California as that area of the state south of Stockton and San Jose, to and including, Bakersfield to the east and San Luis Obispo to the west; and southern California as that area of the state south of Bakersfield and San Luis Obispo.

Cash and Cash Equivalents

Net cash flows are reported for loan and deposit transactions and other borrowings. For purposes of the consolidated statement of cash flows, cash, due from banks with original maturities less than 90 days, interest-earning deposits in other banks, and Federal funds sold are considered to be cash equivalents.

Loans

Loans that Management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the principal amount outstanding, net of deferred loan fees and costs. Loan origination and commitment fees and certain direct loan origination costs are deferred, and the net amount is amortized as an adjustment to the related loan’s yield over the actual life of the loan. Loans on which the accrual of interest has been discontinued are designated as nonaccrual loans.

Loans are placed in nonaccrual status when reasonable doubt exists as to the full, timely collection of interest or principal, or a loan becomes contractually past due by 90 days or more with respect to interest or principal and is not well secured and in the process of collection. When a loan is placed on nonaccrual status, all interest previously accrued but not collected is reversed. Income on such loans is then recognized only to the extent that cash is received and where the future collection of principal is considered probable. Interest accruals

are resumed on such loans only when they are brought fully current with respect to interest and principal and when, in the judgment of Management, the loan is estimated to be fully collectible as to both principal and interest. Accrued interest receivable is not included in the calculation of the allowance for credit losses.

Allowance for Credit Losses - Securities

The Company measures expected credit losses on HTM debt securities on a collective basis by major security type, then further disaggregated by sector and bond rating. Accrued interest receivable on HTM debt securities was considered insignificant at June 30, 2026 and December 31, 2025 and is therefore excluded from the estimate of credit losses. The estimate of expected credit losses considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts based on current and expected changes in credit ratings and default rates. Based on the implied guarantees of the U. S. Government or its agencies related to certain of these investment securities, and the absence of any historical or expected losses, substantially all qualify for a zero loss assumption. Management has separately evaluated its HTM investment securities from obligations of state and political subdivisions utilizing the historical loss data represented by similar securities over a period of time spanning nearly 50 years. As a result of this evaluation, management determined that the expected credit losses associated with these securities is not significant for financial reporting purposes and therefore, no allowance for credit losses has been recognized for any period reported.

The Company evaluates AFS debt securities in an unrealized loss position to determine whether the decline in the fair value below the amortized cost basis (impairment) is due to credit-related factors or noncredit-related factors. Any impairment that is not credit related is recognized in other comprehensive income, net of applicable taxes. Credit-related impairment is recognized as an allowance for credit losses on the balance sheet, limited to the amount by which the amortized cost basis exceeds the fair value, with a corresponding adjustment to earnings. Both the allowance for credit losses and the adjustment to net income may be reversed if conditions change. However, if the Company intends to sell an impaired available for sale debt security or more likely than not will be required to sell such a security before recovering its amortized cost basis, the entire impairment amount is recognized in earnings with a corresponding adjustment to the security's amortized cost basis. In evaluating available for sale debt securities in unrealized loss positions for impairment and the criteria regarding its intent or requirement to sell such securities, the Company considers the extent to which fair value is less than amortized cost, whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred, and the results of reviews of the issuers' financial condition, among other factors. Changes in the allowance for credit losses are recorded as provision for (or reversal of) credit loss expense. Losses are charged against the ACL when management believes the uncollectability of an available for sale debt security is confirmed or when either of the criteria regarding intent or requirement to sell is met. No security credit losses were recognized during the six-month periods ended June 30, 2026 and 2025, respectively.

Loans

Loans that management has the intent and ability to hold until maturity or payoff are reported at principal amount outstanding, net of deferred loan fees and costs. Loans are placed in nonaccrual status when reasonable doubt exists as to the full, timely collection of interest or principal, or a loan becomes contractually past due by 90 days or more with respect to interest or principal and is not well secured and in the process of collection. When a loan is placed on nonaccrual status, all interest previously accrued but not collected is reversed against interest income. Income on such loans is then recognized only to the extent that cash is received and where the future collection of principal is considered probable. Interest accruals are resumed on such loans only when they are brought fully current with respect to interest and principal and when, in the judgment of Management, the loan is estimated to be fully collectible as to both principal and interest. Accrued interest receivable is not included in the calculation of the allowance for credit losses.

Allowance for Credit Losses

The Company performs an ACL evaluation on its loan and lease portfolio and its HTM and AFS securities portfolios. The ACL on loan and lease portfolio and HTM securities are provided through an expected loss methodology referred to as CECL methodology. The ACL on AFS securities is provided when a credit loss is deemed to have occurred for securities which the Company does not intend to sell or is not required to sell. The CECL methodology also applies to credit exposures on off-balance-sheet loan commitments.

Loans

The ACL is a valuation account that is deducted from the loan's amortized cost basis to present the net amount expected to be collected on the loans. Loans are charged off against the allowance when management believes the recorded loan balance is confirmed as uncollectible. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. Regardless of the determination that a charge-off is appropriate for financial accounting purposes, the Company manages its loan portfolio by continually monitoring, where possible, a borrower's ability to pay through the collection of financial information, delinquency status, borrower discussion and the encouragement to repay in accordance with the original contract or modified terms, if appropriate.

The ACL consists of two primary components: (1) the determination of an ACL for loans that are individually identified and analyzed and (2) establishment of an ACL for loans collectively analyzed. To determine the collectively analyzed portion of the ACL, the Company identified various portfolio segments based on loan attributes such as, but not limited to; collateral type and loan purpose or use, to ensure loans with similar risk characteristics are measured on a collective basis. The Company utilizes three different loss model configurations and assigned each of the portfolio segments to one of the three loss model configurations. Historical credit loss experience for financial institutions nationwide, paired with relevant forecasts of macroeconomic conditions, forms the basis for the estimate of expected credit losses amongst the collectively analyzed loan portfolio. Further, each of the three loss model configurations utilized by the Company incorporate unique inputs, such as the following:

(1) Commercial Real Estate: origination vintage, delinquency status, loan-to-value as of the origination date, stated maturity date, property type, and property status

(2) Commercial and Industrial: loan size, credit spread at origination, risk grade, business sector, and loan type

(3) Consumer: FICO, origination vintage, product type, and state geography if applicable

After quantitative considerations, management evaluates the need for additional qualitative adjustments that consider the expected impact of certain factors not fully captured in the quantitative and macroeconomic reserve calculations. These qualitative adjustments may apply to the collectively analyzed pool as a whole, one or more of the three loss models, or to one or more of the loan portfolio segments.

Purchased financial assets with a more-than-insignificant amount of credit deterioration since origination (“PCD assets”) that are measured at amortized cost, the initial allowance for credit losses is added to the purchase price rather than reported as a provision for credit losses. Subsequent changes in the allowance for credit losses on PCD assets are recognized through the provision for credit losses.

HTM Securities

For HTM debt securities, the Company measures expected credit losses on held-to-maturity debt securities on a collective basis by major security type, then further disaggregated by sector and bond rating. Accrued interest receivable on held-to-maturity (HTM) debt securities is excluded from the estimate of credit losses. The estimate of expected credit losses considers historical credit loss information that is adjusted for current condition and reasonable and supportable forecasts based on current and expected changes in credit ratings and default rates. Nearly all of the Company's HTM securities are issued by the U. S. Government entities or agencies, and based on the absence of any historical or expected losses, all qualify for a zero loss assumption. Therefore, no allowance for credit losses has been recognized during the six months ended June 30, 2026 and 2025, respectively.

AFS Securities

The Company evaluates available for sale debt securities in an unrealized loss position to determine whether the decline in the fair value below the amortized cost basis (impairment) is due to credit-related factors or noncredit-related factors. Any impairment that is not credit related is recognized in other comprehensive income, net of applicable taxes. Credit-related impairment is recognized as an allowance for credit losses on the balance sheet, limited to the amount by which the amortized cost basis exceeds the fair value, with a corresponding adjustment to earnings. Both the allowance for credit losses and the adjustment to net income may be reversed if conditions change. However, if the Company intends to sell an impaired available for sale debt security or more likely than not will be required to sell such a security before recovering its amortized cost basis, the entire impairment amount is recognized in earnings with a corresponding adjustment to the security's amortized cost basis. In evaluating available for sale debt securities in unrealized loss positions for impairment and the criteria regarding its intent or requirement to sell such securities, the Company considers the extent to which fair value is less than amortized cost, whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred, and the results of reviews of the issuers' financial condition, among other factors. Changes in the allowance for credit losses are recorded as provision for (or reversal of) credit loss expense. Losses are charged against the ACL when management believes the uncollectability of an available for sale debt security is confirmed or when either of the criteria regarding intent or requirement to sell is met. No security credit losses were recognized during the six months ended June 30, 2026 and 2025, respectively.

Unfunded commitments

The Company is required to include unfunded commitments that are expected to be funded in the future within the allowance for credit loss calculation, other than those that are unconditionally cancellable. To arrive at that reserve, the reserve percentage determined within the same three loss models described above is applied to the unused portion of the expected commitment balance and is multiplied by the expected funding rate. To determine the expected funding rate, the Company uses a historical utilization rate for each segment. The allowance for credit losses for off-balance-sheet credit risk exposures is reported in other liabilities in the condensed consolidated balance sheets.

Note 2 - Investment Securities

The amortized cost, estimated fair values and allowance for credit losses of investments in debt securities are summarized in the following tables:

Proceeds from the sale or call of available for sale investment securities totaled $1.5 million during the three months ended June 30, 2026. with no gross realized gains or losses. Proceeds from the sale or call of available for sale investment securities totaled $0.7 million for the three months ended June 30, 2025, which resulted in gross realized gains of $4.0 thousand. Proceeds from the sale or call of available for sale investment securities totaled $4.5 million and $30.7 million for the six months ended June 30, 2026 and 2025, respectively, resulting in gross realized gains of $17.0 thousand and $1.1 million, respectively.

Investment securities with an aggregate carrying value of $792.7 million and $839.6 million at June 30, 2026 and December 31, 2025, respectively, were pledged as collateral for specific borrowings, lines of credit or local agency deposits.

The amortized cost and estimated fair value of debt securities at June 30, 2026 by contractual maturity are shown below. Actual maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. At June 30, 2026, obligations of the U.S. government and agencies with a cost basis totaling $1.2 billion consist almost entirely of residential real estate mortgage-backed securities whose contractual maturity, or principal repayment, will follow the repayment of the underlying mortgages. For purposes of the following table, the entire outstanding balance of these mortgage-backed securities issued by the U.S. government and agencies is categorized based on final maturity date. At June 30, 2026, the Company estimates the average remaining life of these mortgage-backed securities issued by U.S. government corporations and agencies to be approximately 5.7 years. Average remaining life is defined as the time span after which the principal balance has been reduced by half.

As of June 30, 2026, the contractual final maturity for available for sale and held to maturity investment securities is as follows:

Based on an evaluation of available information including security type, counterparty credit quality, past events, current conditions, and reasonable and supportable forecasts that are relevant to collectability of cash flows, as of June 30, 2026, the Company has concluded that it expects to receive all contractual cash flows from each security held in its AFS and HTM debt securities portfolio. There was no allowance for credit losses related to investment securities as of June 30, 2026 or December 31, 2025.

Gross unrealized losses on debt securities and the fair value of the related securities, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position, were as follows:

The following securities had unrealized losses as of June 30, 2026:

• Obligations of U.S. government corporations and agencies included 161 debt securities with aggregate depreciation of 10.4% from the Company’s amortized cost basis.
• Obligations of states and political subdivisions included 142 debt securities with aggregate depreciation of 9.0% from the Company’s amortized cost basis.
• Corporate bonds included 2 debt securities with aggregate depreciation of 1.1% from the Company’s amortized cost basis.
• Asset backed securities included 18 debt securities with aggregate depreciation of 1.1% from the Company’s amortized cost basis.
• Non-agency collateralized mortgage obligations included 14 debt securities with aggregate depreciation of 13.4% from the Company’s amortized cost basis.

Based on an evaluation of available information including security type, counterparty credit quality, past events, current conditions, and reasonable and supportable forecasts that are relevant to collectability of cash flows, as of June 30, 2026, the Company has concluded that it expects to receive all contractual cash flows from each security held in its AFS and HTM debt securities portfolio. As such, the unrealized losses on these securities were caused by the changes in market interest rates or the widening of market spreads subsequent to the initial purchase of these securities and are not due to the underlying credit of the issuers.

The Company monitors credit quality of debt securities held-to-maturity through the use of credit ratings. The Company monitors the credit rating on a monthly basis. The following table summarizes the amortized cost of debt securities held-to-maturity at the dates indicated, aggregated by credit quality indicator:

Note 3 – Loans

A summary of loan balances at amortized cost are as follows:

Note 4 – Allowance for Credit Losses

For the periods indicated, the following tables summarize the activity in the allowance for credit losses on loans which is recorded as a contra asset, and the reserve for unfunded commitments which is recorded on the balance sheet within other liabilities:

The Company consistently seeks to refine its estimation methodology for determining the allowance for credit losses, the effects of which were insignificant during the current period, and are expected to be insignificant in future periods. Management continues to estimate the appropriate level of reserves using all relevant information, from both internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Management believes the primary risks inherent in the portfolio are a general decline in the economy or GDP, a decline in real estate market values, rising unemployment, increasing vacancy rates, and increases inflation or interest rates in the absence of economic improvement or any other such factors. Any one or a combination of these events may adversely affect a borrower's ability to repay its loan, resulting in increased delinquencies and loan losses. Although Management believes the Company has established and maintained the ACL on loans at appropriate levels, changes in reserves may be necessary if actual economic and other conditions differ substantially from the forecast used in estimating the ACL.

For the periods indicated, the following tables summarize the activity in the allowance for credit losses on loans which is recorded as a contra asset, and the reserve for unfunded commitments which is recorded on the balance sheet within other liabilities:

As part of the on-going monitoring of the credit quality of the Company’s loan portfolio, management tracks certain credit quality indicators including, but not limited to, trends relating to (i) the level of criticized and classified loans, (ii) net charge-offs, (iii) non-performing loans, and (iv) delinquency within the portfolio. The Company analyzes loans individually to classify the loans as to credit risk and grading. This analysis is performed annually for all outstanding balances greater than $1 million and non-homogeneous loans, such as commercial real estate loans, unless other indicators, such as delinquency, trigger more frequent evaluation. Loans below the $1 million threshold and homogenous in nature are evaluated as needed for proper grading based on delinquency and borrower credit scores.

The Company utilizes a risk grading system to assign a risk grade to each of its loans. Loans are graded on a scale ranging from Pass to Loss. A description of the general characteristics of the risk grades is as follows:

• Pass – This grade represents loans ranging from acceptable to very little or no credit risk. These loans typically meet most if not all policy standards in regard to: loan amount as a percentage of collateral value, debt service coverage, profitability, leverage, and working capital.
• Special Mention – This grade represents “Other Assets Especially Mentioned” in accordance with regulatory guidelines and includes loans that display some potential weaknesses which, if left unaddressed, may result in deterioration of the repayment prospects for the asset or may inadequately protect the Company’s position in the future. These loans warrant more than normal supervision and attention.
• Substandard – This grade represents “Substandard” loans in accordance with regulatory guidelines. Loans within this rating typically exhibit weaknesses that are well defined to the point that repayment is jeopardized. Loss potential is, however, not necessarily evident. The underlying collateral supporting the credit appears to have sufficient value to protect the Company from loss of principal and accrued interest, or the loan has been written down to the point where this is true. There is a definite need for a well-defined workout/rehabilitation program.
• Doubtful – This grade represents “Doubtful” loans in accordance with regulatory guidelines. An asset classified as Doubtful has all the weaknesses inherent in a loan classified Substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. Pending factors include proposed merger, acquisition, or liquidation procedures, capital injection, perfecting liens on additional collateral, and financing plans.
• Loss – This grade represents “Loss” loans in accordance with regulatory guidelines. A loan classified as Loss is considered uncollectible and of such little value that its continuance as a bankable asset is not warranted. This classification does not mean that the loan has absolutely no recovery or salvage value, but rather that it is not practical or desirable to defer writing off the loan, even though some recovery may be affected in the future. The portion of the loan that is graded loss should be charged off no later than the end of the quarter in which the loss is identified.

Based on the most recent analysis performed, the risk category of loans by class of loans is as follows for the period indicated:

The following table shows the ending balance of current and past due originated loans by loan category as of the date indicated:

The following table shows the ending balance of non accrual loans by loan category as of the date indicated:

Interest income on non accrual loans that would have been recognized during the three months ended June 30, 2026 and 2025, if all such loans had been current in accordance with their original terms, totaled $1.3 million and $2.1 million, respectively. Interest income actually recognized on these originated loans during the three months ended June 30, 2026 and 2025 was $144.0 thousand and $339.0 thousand, respectively.

The following tables present the amortized cost basis of collateral dependent loans by class of loans as of the following periods:

Modifications to borrowers experiencing financial difficulty may include interest rate reductions, principal or interest forgiveness, forbearance, term extensions, and other actions intended to minimize economic loss and to avoid foreclosure or repossession of collateral.

During the three and six months ended June 30, 2026 and June 30, 2025, respectively, there were no significant loan modifications made to borrowers experiencing financial difficulty. During the three and six months ended June 30, 2026 and June 30, 2025, respectively, there were no loans with payment defaults by borrowers experiencing financial difficulty which had material modifications in rate, term or principal forgiveness during the twelve months prior to default.

Note 5 - Leases

The Company records a ROUA on the consolidated balance sheets for those leases that convey rights to control use of identified assets for a period of time in exchange for consideration. The Company also records a lease liability on the consolidated balance sheets for the present value of future payment commitments. All of the Company’s leases are comprised of operating leases in which the Company is lessee of real estate property for branches, ATM locations, and general administration and operations. The Company has elected not to include short-term leases (i.e. leases with initial terms of 12 month or less) within the ROUA and lease liability.

The following table presents the components of lease expense for the periods ended:

The following table presents supplemental cash flow information related to leases for the periods ended:

A summary of the balances of deposits follows:

Certificate of deposit balances totaling $100.0 million from the State of California were included in time certificates, $250,000 or more, at June 30, 2026 and December 31, 2025, respectively. The Company participates in a deposit program offered by the State of California whereby the State may make deposits at the Company’s request subject to collateral and credit worthiness constraints. The negotiated rates on these State deposits are generally more favorable than other wholesale funding sources available to the Company.

Overdrawn deposit balances of $2.5 million and $2.7 million were classified as consumer loans at June 30, 2026 and December 31, 2025, respectively.

Note 7 - Other Borrowings

Note 9 - Commitments and Contingencies

The following table presents a summary of the Bank’s commitments and contingent liabilities:

In April 2024, Visa Inc. announced the commencement of an exchange offer for Visa Class B-1 common stock and the Company subsequently tendered all of its Visa Class B-1 common stock in exchange for a combination of Visa Class B-2 common stock and Visa Class C common stock. Visa Class B-2 common stock continues to be carried at zero. The Bank owns 6,698 shares of Class B-2 common stock of Visa Inc. which may be convertible into Class A common stock at a conversion ratio of 1.5014 per Class B-2 share. As of June 30,

2026, the value of the Class A shares was $343.09 per share. Utilizing the conversion ratio, the value of unredeemed Class A equivalent shares owned by the Bank was $3.5 million as of June 30, 2026, and has not been reflected in the accompanying consolidated financial statements.

Note 10 - Shareholders’ Equity

Dividends Paid

The Bank paid to the Company cash dividends in the aggregate amounts of $35.1 million and $28.5 million during the three months ended June 30, 2026 and 2025, respectively, and during the equivalent six month periods paid $46.6 million and $40.6 million, respectively. The Bank is regulated by the FDIC and the DFPI. Absent approval from the Commissioner of the DFPI, California banking laws generally limit the Bank’s ability to pay dividends to the lesser of (1) retained earnings or (2) net income for the last three fiscal years, less cash distributions paid during such period.

Stock Repurchase Plan

The Company's Board of Directors has approved the authorization to repurchase up to 2.0 million shares of the Company's common stock (the 2025 Repurchase Plan or the 2025 Program). The Company’s 2025 Repurchase Plan replaces and supersedes the 2021 Share Repurchase Program which has been terminated as of December 31, 2025. The actual timing of any share repurchases will be determined by the Company's management and therefore the total value of the shares to be purchased under the 2025 Program is subject to change. The 2025 Program has no expiration date but the Board may suspend or discontinue the program at any time.

During the three months ended June 30, 2026, the Company repurchased zero shares. During the six months ended June 30, 2026, the Company repurchased 447,211 shares with a market value totaling $21.6 million under the 2025 Program. There were no shares repurchased in 2025 under the 2025 Program, however, during the three and six months ended June 30, 2025 the Company purchased 379,978 and 469,632 shares with market values of $15.2 million and $18.9 million under the 2021 Share Repurchase Program. As of June 30, 2026, approximately 1,553,000 shares remain authorized for repurchase.

Stock Repurchased Under Equity Compensation Plans

The Company's shareholder-approved equity compensation plans permit employees to tender recently vested shares in lieu of cash for the payment of exercise price, if applicable, and the tax withholding on such shares. There were no option exercises during the three and six months ended June 30, 2026 and 2025, respectively. Employees tendered 33,379 and 11,542 shares in connection with the tax withholding requirements of other share-based awards during the three months ended June 30, 2026 and 2025, respectively, and 50,641 and 21,664 shares during the six months then ended, respectively. In total, shares of the Company's common stock tendered had market values of $1.8 million and $0.5 million during the quarters ended June 30, 2026 and 2025, respectively, and $2.6 million and $0.9 million during the respective six month periods. The tendered shares were retired. The market value of tendered shares is the last market trade price at closing on the day an option is exercised or the other share-based award vests. Stock repurchased under equity incentive plans are not included in the total of stock repurchased under the 2025 Program.

Note 11 - Stock Options and Other Equity-Based Incentive Instruments

On April 16, 2024, the Board of Directors adopted the 2024 Equity Incentive Plan (2024 Plan) which was approved by shareholders on May 23, 2024. The 2024 Plan allows for up to 1,200,000 shares to be issued in connection with equity-based incentives. In conjunction with shareholder approval of the 2024 Plan, the 2019 Equity Incentive Plan (2019 Plan), which allowed for up to 1,500,000 shares to be issued in connection with equity-based incentives, is no longer available for grant issuances. While no new awards can be granted under the 2019 Plan, existing grants continue to be governed by the terms, conditions and procedures set forth in any applicable award agreement.

There were no stock options outstanding as of June 30, 2026 and December 31, 2025.

Activity related to restricted stock unit awards during the six months ended June 30, 2026 is summarized in the following table:

The 125,774 of service condition vesting RSUs outstanding as of June 30, 2026 include a feature whereby each RSU outstanding is credited with a dividend amount equal to any common stock cash dividend declared and paid, and the credited amount is divided by the closing price of the Company’s stock on the dividend payable date to arrive at an additional amount of RSUs outstanding under the original grant. The dividend credits follow the same vesting requirements as the RSU awards and are not considered participating securities. The 125,774 of service condition vesting RSUs outstanding as of June 30, 2026 are expected to vest, and be released, on a weighted-average basis, over the next 2.00 years. The Company expects to recognize $4.4 million of pre-tax compensation costs related to these service condition vesting RSUs between June 30, 2026 and their vesting dates. The Company did not modify any service condition vesting RSUs during the six months ended June 30, 2026 or 2025.

The 142,096 of market plus service condition vesting RSUs outstanding as of June 30, 2026 are expected to vest, and be released, on a weighted-average basis, over the next 2.30 years. The Company expects to recognize $2.4 million of pre-tax compensation costs related to these RSUs between June 30, 2026 and their vesting dates. As of June 30, 2026, the number of market plus service condition vesting RSUs outstanding that will actually vest, and be released, may be reduced to zero or increased to 213,144 depending on the total return of the Company’s common stock versus the total return of an index of bank stocks from the grant date to the vesting date. The Company did not modify any market plus service condition vesting RSUs during the six months ended June 30, 2026 or 2025.

Note 12 - Non-interest Income and Expense

The following tables summarize the Company’s non-interest income for the periods indicated:

The following tables summarize the Company’s non-interest expense for the periods indicated:

Note 13 - Earnings Per Share

Basic earnings per share represent income available to common shareholders divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per share reflect additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustments to income that would result from assumed issuance. Potential common shares that may be issued by the Company relate to outstanding stock options and restricted stock units (RSUs), and are determined using the treasury stock method. Earnings per share have been computed based on the following:

Note 14 – Comprehensive (Loss) Income

Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities, such as unrealized gains and losses on available-for-sale securities, are reported as a separate component of the equity section of the balance sheet identified as AOCI, such items, along with net income, are components of OCI.

The components of OCI and related tax effects are as follows:

The components of AOCI, included in shareholders’ equity, are as follows:

Note 15 - Fair Value Measurement

The Company utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. In estimating fair value, the Company utilizes valuation techniques that are consistent with the market approach, income approach, and/or the cost approach. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset or liability including assumptions about the risk inherent in a particular valuation technique, the effect of a restriction on the sale or use of an asset and the risk of nonperformance. Marketable equity securities, trading securities, debt securities available-for-sale, loans held for sale, and mortgage servicing rights are recorded at fair value on a recurring basis. Additionally, from time to time, the Company may be required to record at fair value other assets on a nonrecurring basis, such loans held for investment and certain other assets. These nonrecurring fair value adjustments typically involve application impairment write-downs of individual assets.

The Company groups assets and liabilities at fair value in three levels, based on the markets in which the assets and liabilities are traded and the observable nature of the assumptions used to determine fair value. These levels are:

Level 1 - Valuation is based upon quoted prices for identical instruments traded in active markets.

Level 2 - Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market.

Level 3 - Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability.

Valuation techniques include use of option pricing models, discounted cash flow models and similar techniques.

Marketable equity securities, trading securities and debt securities available for sale - Marketable equity, trading and debt securities available for sale are recorded at fair value on a recurring basis. Fair value measurement is based upon quoted prices, if available. If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security’s credit rating, prepayment assumptions and other factors such as credit loss assumptions. Level 1 securities include those traded on an active exchange, such as the New York Stock Exchange, U.S. Treasury securities that are traded by dealers or brokers in active over-the-counter markets and money market funds. Level 2 securities include mortgage-backed securities issued by government sponsored entities, municipal bonds and corporate debt securities. The Company had no securities classified as Level 3 during any of the periods covered in these consolidated financial statements.

Loans held for sale - Loans held for sale are carried at the lower of cost or fair value. The fair value of loans held for sale is based on what secondary markets are currently offering for loans with similar characteristics. As such, we classify those loans subjected to recurring fair value adjustments as Level 2.

Collateral dependent loans - Loans are not recorded at fair value on a recurring basis. However, from time to time, certain loans have individual risk characteristics not consistent with a pool of loans and is individually evaluated for credit reserves. Loans for which it is probable that payment of interest and principal will not be made in accordance with the original contractual terms of the loan agreement are typically individually evaluated. The fair value of these loans are estimated using one of several methods, including collateral value, fair value of similar debt, enterprise value, liquidation value and discounted cash flows. Those loans not requiring an allowance represent loans for which the fair value of the expected repayments or collateral exceed the recorded investments in such loans. Loans where an allowance is established based on the fair value of collateral require classification in the fair value hierarchy. When the fair value of the collateral is based on an observable market price or a current appraised value which uses substantially observable data, the Company records the loan as nonrecurring Level 2. When an appraised value is not available or management determines the fair value of the collateral is further impaired below the appraised value, or the appraised value contains a significant unobservable assumption, such as deviations from comparable sales, and there is no observable market price, the Company records the loan as nonrecurring Level 3.

Foreclosed assets - Foreclosed assets include assets acquired through, or in lieu of, loan foreclosure. Foreclosed assets are held for sale and are initially recorded at fair value at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, management periodically performs valuations and the assets are carried at the lower of carrying amount or fair value less cost to sell. When the fair value of foreclosed assets is based on an observable market price or a current appraised value which uses substantially observable data, the Company records the loan as nonrecurring Level 2. When an appraised value is not available or management determines the fair value of the collateral is further impaired below the appraised value, or the appraised value contains a significant unobservable assumption, such as deviations from comparable sales, and there is no observable market price, the Company records the foreclosed asset as nonrecurring Level 3. Revenue and expenses from operations and changes in the valuation allowance are included in other non-interest expense.

Mortgage servicing rights - Mortgage servicing rights are carried at fair value. A valuation model, which utilizes a discounted cash flow analysis using a discount rate and prepayment speed assumptions is used in the computation of the fair value measurement. While the prepayment speed assumption is currently quoted for comparable instruments, the discount rate assumption currently requires a significant degree of management judgment and is therefore considered an unobservable input. As such, the Company classifies mortgage servicing rights subjected to recurring fair value adjustments as Level 3.

The table below presents the recorded amount of assets and liabilities measured at fair value on a recurring basis (in thousands):

Transfers between levels of the fair value hierarchy are recognized on the actual date of the event or circumstances that caused the transfer, which generally corresponds with the Company’s quarterly valuation process. There were no transfers between any levels during the six months ended June 30, 2026 or June 30, 2025, respectively.

The following table provides a reconciliation of assets and liabilities measured at fair value using significant unobservable inputs (Level 3) on a recurring basis during the time periods indicated. Had there been any transfer into or out of Level 3 during the time periods indicated, the amount included in the “Transfers into (out of) Level 3” column would represent the beginning balance of an item in the period (interim quarter) during which it was transferred (in thousands):

Six months ended June 30,

The key unobservable inputs used in determining the fair value of mortgage servicing rights are mortgage prepayment speeds and the discount rate used to discount cash projected cash flows. Generally, any significant increases in the mortgage prepayment speed and discount rate utilized in the fair value measurement of the mortgage servicing rights will result in a negative fair value adjustments (and decrease in the fair value measurement). Conversely, a decrease in the mortgage prepayment speed and discount rate will result in a positive fair value adjustment (and increase in the fair value measurement).

The following table presents quantitative information about recurring Level 3 fair value measurements at June 30, 2026 and December 31, 2025:

The tables below present the recorded investment in assets and liabilities measured at fair value on a nonrecurring basis, as of the dates indicated, that had a write-down or an additional allowance provided during the periods indicated (in thousands):

The tables below present the net (losses) gains resulting from non-recurring fair value adjustments of assets and liabilities for the periods indicated (in thousands):

The individually evaluated loan amounts above represent collateral dependent loans that have been adjusted to fair value. When the Company identifies a collateral dependent loan with unique risk characteristics, the Company evaluates the need for an allowance using the current fair value of the collateral, less selling costs. Depending on the characteristics of a loan, the fair value of collateral is generally estimated by obtaining external appraisals. If the Company determines that the value of the loan is less than the recorded investment in the loan, the Company recognizes this impairment and adjust the carrying value of the loan to fair value through the allowance for credit losses. The loss represents charge-offs or impairments on collateral dependent loans for fair value adjustments based on the fair value of collateral. The carrying value of loans fully charged-off is zero.

The foreclosed assets amounts above represents impaired real estate that has been adjusted to fair value. Foreclosed assets represent real estate which the Company has taken control of in partial or full satisfaction of loans. At the time of foreclosure, other real estate owned is recorded at fair value less costs to sell, which becomes the property’s new basis. Any write-downs based on the asset’s fair value at the date of acquisition are charged to the allowance for credit losses. After foreclosure, management periodically performs valuations such that the real estate is carried at the lower of its new cost basis or fair value, net of estimated costs to sell. Fair value adjustments on other real estate owned are recognized within net loss on real estate owned. The loss represents impairments on real estate owned for fair value adjustments based on the fair value of the real estate.

The Company’s property appraisals are primarily based on the sales comparison approach and income approach methodologies, which consider recent sales of comparable properties, including their income generating characteristics, and then make adjustments to reflect the general assumptions that a market participant would make when analyzing the property for purchase. These adjustments may increase or decrease an appraised value and can vary significantly depending on the location, physical characteristics and income producing potential of each property. Additionally, the quality and volume of market information available at the time of the appraisal can vary from period to period and cause significant changes to the nature and magnitude of comparable sale adjustments. Given these variations, comparable sale adjustments are generally not a reliable indicator for how fair value will increase or decrease from period to period. Under certain circumstances, management discounts are applied based on specific characteristics of an individual property.

The following table presents quantitative information about Level 3 fair value measurements for financial instruments measured at fair value on a nonrecurring basis at June 30, 2026:

The following table presents quantitative information about Level 3 fair value measurements for financial instruments measured at fair value on a nonrecurring basis at December 31, 2025:

Fair values for financial instruments are management’s estimates of the values at which the instruments could be exchanged in a transaction between willing parties. The Company uses the exit price notion when measuring the fair value of financial instruments. These estimates are subjective and may vary significantly from amounts that would be realized in actual transactions. In addition, other significant assets are not considered financial assets including, any mortgage banking operations, deferred tax assets, and premises and equipment. Further, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on the fair value estimates and have not been considered in any of these estimates.

Note 16 - Regulatory Matters

The Company is subject to various regulatory capital requirements administered by federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company must meet specific capital guidelines that involve quantitative measures of the Company’s assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. The Company’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors.

Quantitative measures established by regulation to ensure capital adequacy require the Company to maintain minimum amounts and ratios (set forth in the table below) of total, Tier 1, and common equity Tier 1 capital to risk-weighted assets, and of Tier 1 capital to average assets. The following tables present actual and required capital ratios as of June 30, 2026 and December 31, 2025 for the Company and the Bank under applicable Basel III Capital Rules. The minimum capital amounts presented include the minimum required capital levels as of June 30, 2026 and December 31, 2025 based on the then phased-in provisions of the Basel III Capital Rules. Capital levels required to be considered well capitalized are based upon prompt corrective action regulations, as amended to reflect the changes under the Basel III Capital Rules.

As of June 30, 2026 and December 31, 2025, capital levels at the Company and the Bank exceed all capital adequacy requirements under the Basel III Capital Rules. Also, at June 30, 2026 and December 31, 2025, the Bank’s capital levels exceeded the minimum amounts necessary to be considered well capitalized under the current regulatory framework for prompt corrective action.

The Basel III Capital Rules require all banking organizations to maintain a capital conservation buffer above the minimum risk-based capital requirements in order to avoid certain limitations on capital distributions, stock repurchases and discretionary bonus payments to executive officers. The capital conservation buffer is exclusively composed of common equity tier 1 capital, and it applies to each of the risk-based capital ratios but not the leverage ratio. At June 30, 2026, the Company and the Bank are in compliance with the capital conservation buffer requirement.

Note 18 — Pending Merger

On July 12, 2026, TriCo entered into an Agreement and Plan of Reorganization and Merger (the “merger agreement”) with First Hawaiian, Inc., a Delaware corporation (“First Hawaiian”) and Horizon Merger Sub, Inc., a California corporation and wholly owned subsidiary of First Hawaiian (“Merger Sub”). The merger agreement provides that, upon the terms and subject to the conditions set forth therein, Merger Sub will merge with and into TriCo (the “merger”), with TriCo surviving the merger (the “Surviving Corporation”), and immediately following the merger, the Surviving Corporation will merge with and into First Hawaiian (the “second step merger,” and together with the merger, the “mergers”), with First Hawaiian continuing as the surviving entity in the second step merger. Promptly following the second step merger, Tri Counties Bank will merge with and into First Hawaiian’s wholly owned bank subsidiary, First Hawaiian Bank (the “bank merger”), with First Hawaiian Bank surviving the bank merger. The merger agreement was unanimously approved and adopted by the board of directors of each of TriCo, FHI and Merger Sub.

Subject to the terms and conditions of the merger agreement, at the effective time of the merger (the “effective time”), each share of TriCo common stock outstanding immediately prior to the effective time, other than shares owned, directly or indirectly, by TriCo, First Hawaiian or any of their respective subsidiaries, will be converted into the right to receive 2.095 shares of common stock, par value $0.01 per share, of First Hawaiian. Holders of TriCo’s common stock will receive cash in lieu of fractional shares. Upon closing of the transaction, First Hawaiian and TriCo shareholders are expected to own approximately 65% and 35%, respectively, of the combined company.

The transaction is expected to close by the end of 2026, subject to the receipt of required regulatory approvals, approval by First Hawaiian and TriCo shareholders and the satisfaction of customary closing conditions. A summary of the terms of the merger agreement and other related agreements are summarized in, and the merger agreement has been filed as an exhibit to, the Current Report on Form 8-K filed by the Company with the Securities and Exchange Commission on July 15, 2026.
