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 has five capital subsidiary business trusts (collectively, the “Capital Trusts”) that issued trust preferred securities, including two organized by the Company and three acquired with the acquisition of North Valley Bancorp. For financial reporting purposes, the Company’s investments in the Capital Trusts of $1.8 million are accounted for under the equity method and, accordingly, are not consolidated and are included in other assets on the consolidated balance sheet. See the Note 8 - footnote Junior Subordinated Debt for additional information on borrowings outstanding.
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, 2023 (the “2023 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. The Company currently classifies all its operation into one business segment that it denotes as community banking.
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.
Reclassification
Some items in the prior year consolidated financial statements were reclassified to conform to the current presentation. Reclassifications had no effect on prior year net income or shareholders’ equity.
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.
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 September 30, 2024 and December 31, 2023 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

Table of Contents
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 nine month periods ended September 30, 2024 and 2023, 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 - 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.
Management estimates the allowance balance using relevant information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. The allowance for credit losses is measured on a collective (pool) basis when similar risk characteristics exist. Historical credit loss experience provides the basis for the estimation of expected credit losses, which captures loan balances as of a point in time to form a cohort, then tracks the respective losses generated by that cohort of loans over the remaining life. The Company identified and accumulated loan cohort historical loss data beginning with the fourth quarter of 2008 and through the current period. In situations where the Company's actual loss history was not statistically relevant, the loss history of peers, defined as financial institutions with assets greater than three billion and less than ten billion, were utilized to create a minimum loss rate. Adjustments to historical loss information are made for differences in relevant current loan-specific risk characteristics, such as historical timing of losses relative to the loan origination. In its loss forecasting framework, the Company incorporates forward-looking information through the use of macroeconomic scenarios applied over the forecasted life of the assets. These macroeconomic scenarios incorporate variables that have historically been key drivers of increases and decreases in credit losses. These variables include, but are not limited to changes in environmental conditions, such as California unemployment rates, household debt levels, changes in corporate debt yields, and U.S. gross domestic product.
PCD assets are assets acquired at a discount that is due, in part, to credit quality deterioration since origination. PCD assets are accounted for in accordance with ASC 326-20 and are initially recorded at fair value, by taking the sum of the present value of expected future cash flows and an allowance for credit losses, at acquisition. The allowance for credit losses for PCD assets is recorded through a gross-up of reserves on the balance sheet, while the allowance for acquired non-PCD assets, such as loans, is recorded through the provision for credit losses on the income statement, consistent with originated loans. Subsequent to acquisition, the allowance for credit losses for PCD loans will generally follow the same forward-looking estimation, provision, and charge-off process as non-PCD acquired and originated loans.
The Company has identified the following portfolio segments to evaluate and measure the allowance for credit loss:
Commercial real estate:
Commercial real estate - Non-owner occupied: These commercial properties typically consist of buildings which are leased to others for their use and rely on rents as the primary source of repayment. Property types are predominantly office, retail, or light industrial but the portfolio also has some special use properties. As such, the risk of loss associated with these properties is primarily driven by general

Table of Contents
economic changes or changes in regional economies and the impact of such on a tenant’s ability to pay. Ultimately this can affect occupancy, rental rates, or both. Additional risk of loss can come from new construction resulting in oversupply, the costs to hold or operate the property, or changes in interest rates. The terms on these loans at origination typically have maturities from five to ten years with amortization periods from fifteen to thirty years.
Commercial real estate - Owner occupied: These credits are primarily susceptible to changes in the financial condition of the business operated by the property owner. This may be driven by changes in, among other things, industry challenges, factors unique to the operating geography of the borrower, change in the individual fortunes of the business owner, general economic conditions and changes in business cycles. When default is driven by issues related specifically to the business owner, collateral values tend to provide better repayment support and may result in little or no loss. Alternatively, when default is driven more by general economic conditions, the underlying collateral may have devalued more and thus result in larger losses in the event of default. The terms on these loans at origination typically have maturities from five to ten years with amortization periods from fifteen to thirty years.
Multifamily: These commercial properties are generally comprised of more than four rentable units, such as apartment buildings, with each unit intended to be occupied as the primary residence for one or more persons. Multifamily properties are also subject to changes in general or regional economic conditions, such as unemployment, ultimately resulting in increased vacancy rates or reduced rents or both. In addition, new construction can create an oversupply condition and market competition resulting in increased vacancy, reduced market rents, or both. Due to the nature of their use and the greater likelihood of tenant turnover, the management of these properties is more intensive and therefore is more critical to the preclusion of loss.
Farmland: While the Company has few loans that were originated for the purpose of the acquisition of these commercial properties, loans secured by farmland represent unique risks that are associated with the operation of an agricultural businesses. The valuation of farmland can vary greatly over time based on the property's access to resources including but not limited to water, crop prices, foreign exchange rates, government regulation or restrictions, and the nature of ongoing capital investment needed to maintain the quality of the property. Loans secured by farmland typically represent less risk to the Company than other agriculture loans as the real estate typically provides greater support in the event of default or need for longer term repayment.
Consumer loans:
SFR 1-4 1st DT Liens: The most significant drivers of potential loss within the Company's residential real estate portfolio relate general, regional, or individual changes in economic conditions and their effect on employment and borrowers cash flow. Risk in this portfolio is best measured by changes in borrower credit score and loan-to-value. Loss estimates are based on the general movement in credit score, economic outlook and its effects on employment and the value of homes and the Bank’s historical loss experience adjusted to reflect the economic outlook and the unemployment rate.
SFR HELOCs and Junior Liens: Similar to residential real estate term loans, HELOCs and junior liens performance is also primarily driven by borrower cash flows based on employment status. However, HELOCs carry additional risks associated with the fact that most of these loans are secured by a deed of trust in a position that is junior to the primary lien holder. Furthermore, the risk that as the borrower's financial strength deteriorates, the outstanding balance on these credit lines may increase as they may only be canceled by the Company if certain limited criteria are met. In addition to the allowance for credit losses maintained as a percent of the outstanding loan balance, the Company maintains additional reserves for the unfunded portion of the HELOC.
Other: The majority of consumer loans are secured by automobiles, with the remainder primarily unsecured revolving debt (credit cards). These loans are susceptible to three primary risks; non-payment due to income loss, over-extension of credit and, when the borrower is unable to pay, shortfall in collateral value, if any. Typically non-payment is due to loss of job and will follow general economic trends in the marketplace driven primarily by rises in the unemployment rate. Loss of collateral value can be due to market demand shifts, damage to collateral itself or a combination of those factors. Credit card loans are unsecured and while collection efforts are pursued in the event of default, there is typically limited opportunity for recovery. Loss estimates are based on the general movement in credit score, economic outlook and its effects on employment and the Bank’s historical loss experience adjusted to reflect the economic outlook and the unemployment rate.
Commercial and Industrial:
Repayment of these loans is primarily based on the cash flow of the borrower, and secondarily on the underlying collateral provided by the borrower. A borrower's cash flow may be unpredictable, and collateral securing these loans may fluctuate in value. Most often, collateral includes accounts receivable, inventory, or equipment. Collateral securing these loans may depreciate over time, may be difficult to appraise, may be illiquid and may fluctuate in value based on the success of the business. Actual and forecast changes in gross domestic product are believed to be corollary to losses associated with these credits.
Construction:
While secured by real estate, construction loans represent a greater level of risk than term real estate loans due to the nature of the additional risks associated with the not only the completion of construction within an estimated time period and budget, but also the need to either sell the building or reach a level of stabilized occupancy sufficient to generate the cash flows necessary to support debt service and operating costs. The Company seeks to mitigate the additional risks associated with construction lending by requiring borrowers to comply with lower loan to value ratios and additional covenants as well as strong tertiary support of guarantors. The loss forecasting model applies the historical rate of loss for similar loans over the expected life of the asset as adjusted for macroeconomic factors.

Table of Contents
Agriculture Production:
Repayment of agricultural loans is dependent upon successful operation of the agricultural business, which is greatly impacted by factors outside the control of the borrower. These factors include adverse weather conditions, including access to water, that may impact crop yields, loss of livestock due to disease or other factors, declines in market prices for agriculture products, changes in foreign exchange, and the impact of government regulations. In addition, many farms are dependent on a limited number of key individuals whose injury or death may significantly affect the successful operation of the business. Consequently, agricultural production loans may involve a greater degree of risk than other types of loans.
Leases:
The loss forecasting model applies the historical rate of loss for similar loans over the expected life of the asset. Leases typically represent an elevated level of credit risk as compared to loans secured by real estate as the collateral for leases is often subject to a more rapid rate of depreciation or depletion. The ultimate severity of loss is impacted by the type of collateral securing the exposure, the size of the exposure, the borrower’s industry sector, any guarantors and the geographic market. Assumptions of expected loss are conditioned to the economic outlook and the other variables discussed above.
Unfunded commitments:
The estimated credit losses associated with these unfunded lending commitments is calculated using the same models and methodologies noted above and incorporate utilization assumptions at time of default. The reserve for unfunded commitments is maintained on the consolidated balance sheet in other liabilities.

Proceeds from the sale of available for sale investment securities totaled $28.6 million and $24.2 million for the nine months ended September 30, 2024 and 2023, respectively, resulting in gross realized losses of $2.9 million and $0.2 million, respectively. In addition, during the nine months ended September 30, 2024, the Company participated in and completed an exchange offering with Visa, which resulted in a gain of $2.9 million. See further discussion in Note 9 - Commitments and Contingencies. There were no sales of investment securities during the three months ended September 30, 2024 or 2023. Investment securities with an aggregate carrying value of $761.6 million and $702.2 million at September 30, 2024 and December 31, 2023, 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 September 30, 2024 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 September 30, 2024, obligations of U.S. government corporations and agencies with a cost basis totaling $1.3 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 U.S. government corporations and agencies is categorized based on final maturity date. At September 30, 2024, the Company estimates the average remaining life of these mortgage-backed securities issued by U.S. government corporations and agencies to be approximately 6.67 years. Average remaining life is defined as the time span after which the principal balance has been reduced by half.

Obligations of U.S. government agencies: The unrealized losses on investments in obligations of U.S. government agencies are caused by interest rate increases and illiquidity. The contractual cash flows of these securities are guaranteed by U.S. Government Sponsored Entities (principally Fannie Mae and Freddie Mac). It is expected that the securities would not be settled at a price less than the amortized cost of the investment. Because management believes the decline in fair value is attributable to changes in interest rates and not credit quality, and because the Company does not intend to sell and more likely than not will not be required to sell, there is no impairment on these securities

In determining the allowance for credit losses, accruing loans with similar risk characteristics are generally evaluated collectively. To estimate expected losses the Company generally utilizes historical loss trends and the remaining contractual lives of the loan portfolios to determine estimated credit losses through a reasonable and supportable forecast period. Individual loan credit quality indicators including loan grade and borrower repayment performance have been statistically correlated with historical credit losses and various econometrics,

including California unemployment, gross domestic product, and corporate bond yields. Model forecasts may be adjusted for inherent limitations or biases that have been identified through independent validation and back-testing of model performance to actual realized results.
The Company utilizes a forecast period of approximately eight quarters and obtains the forecast data from publicly available sources as of the balance sheet date. This forecast data continues to evolve and includes improving shifts in the magnitude of changes for both the unemployment and GDP factors leading up to the balance sheet date. Core inflation is slowing but prices remain elevated relative to wage increases, as reflected by higher living costs such as housing, energy and general services. Actions by the Federal Reserve to cut rates during 2024 and beyond may help improve this outlook overall, but the uncertainty associated with the extent and timing of these potential reductions has inhibited a material change to forecasted reserve levels. Furthermore, geopolitical risks remain elevated and appear to be getting worse, which may lead to further negative effects on domestic economic outcomes. As a result, management continues to believe that certain credit weaknesses are present in the overall economy and that it is appropriate to maintain a reserve level that incorporates such risk factors.
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:

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. Known or determinable adjustments to the required minimum future lease payments were included in the calculation of the Company’s ROUA and lease liability. Adjustments to the required minimum future lease payments that are variable and will not be determinable until a future period, such as changes in the consumer price index, are included as variable lease costs. Additionally, expected variable payments for common area maintenance, taxes and insurance were unknown and not determinable at lease commencement and therefore, were not included in the determination of the Company’s ROUA or lease liability.
The value of the ROUA and lease liability is impacted by the amount of the periodic payment required, length of the lease term, and the discount rate used to calculate the present value of the minimum lease payments. The Company’s lease agreements often include one or more options to renew at the Company’s discretion. If at lease inception, the Company considers the exercising of a renewal option to be reasonably certain, the Company will include the extended term in the calculation of the ROU asset and lease liability. Topic 842 requires the use of the rate implicit in the lease whenever this rate is readily determinable. As this rate is rarely determinable, the Company utilizes its incremental borrowing rate at lease inception, on a collateralized basis, over a similar term. The lease liability is reduced based on the discounted present value of remaining payments as of each reporting period. The ROUA value is measured using the amount of lease liability and adjusted for prepaid or accrued lease payments, remaining lease incentives, unamortized direct costs (if any), and impairment (if any).

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. Completion of the exchange resulted in a gain of $2.9 million relating to the 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 1.5875 per Class B-2 share. As of September 30, 2024, the value of the Class A shares was $274.95 per share. Utilizing the conversion ratio, the value of unredeemed Class A equivalent shares owned by the Bank was $2.9 million as of September 30, 2024, and has not been reflected in the accompanying consolidated financial statements. The shares of Visa Class B-2 common stock are restricted and may not be transferred. Visa Member Banks are required to fund an escrow account to cover settlements, resolution of pending litigation and related claims. If the funds in the escrow account are insufficient to settle all the covered litigation, Visa may sell additional Class A shares, use the proceeds to settle litigation, and further reduce the conversion ratio. If funds remain in the escrow account after all litigation is settled, the Class B-2 conversion ratio may be increased to reflect that surplus. Until all U.S. covered litigation obligations have been satisfied or the Applicable Conversion Rate for the Class B-2 common stock reaches zero, there is no dollar cap on the amount of payments that a participating holder and its guarantors may be obligated to make under its Makewhole Agreement.

Note 10 - Shareholders’ Equity
Dividends Paid
The Bank paid to the Company cash dividends in the aggregate amounts of $10.5 million and $11.5 million during the three months ended September 30, 2024 and 2023, respectively and $54.4 million and $41.4 million during the equivalent nine month periods then ended, 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
On February 25, 2021, the Board of Directors authorized the repurchase of up to 2.0 million shares of the Company's common stock (the 2021 Repurchase Plan), which approximated 6.7% of the shares outstanding as of the approval date. The actual timing of any share repurchases can be determined by the Company's management and therefore the total value of the shares to be purchased under the 2021 Repurchase Plan is subject to change. The 2021 Repurchase Plan has no expiration date (in accordance with applicable laws and regulations). During the three and nine months ended September 30, 2024, the Company repurchased zero and 344,324 shares with market values of $0.0 million and $12.5 million, respectively. During the three and nine months ended September 30, 2023, the Company repurchased zero and 150,000 shares with market values of zero and $7.0 million, respectively.
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. During the three and nine months ended September 30, 2023, exercising option holders tendered zero and 2,506 shares, respectively, of the Company’s common stock in connection with option exercises. There were no option exercises during the nine months ended September 30, 2024. Employees also tendered 1,551 and 976 shares in connection with the tax withholding requirements of other share-based awards during the three months ended September 30, 2024 and 2023, respectively, and 32,061 and 52,437 during the nine months ended September 30, 2024 and 2023, respectively. In total, shares of the Company's common stock tendered had market values of $0.1 million and $0.03 million during the quarters ended September 30, 2024 and 2023, respectively and $1.2 million and $2.1 million, respectively during the year to date periods then ended. 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 2021 Stock Repurchase Plans.
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. The Company's 2009 Equity Incentive Plan expired on March 26, 2019. While no new awards can be granted under the 2019 Plan or 2009 Plan, existing grants continue to be governed by the terms, conditions and procedures set forth in any applicable award agreement.
Stock option activity during the nine months ended September 30, 2024, is summarized in the following table:

Activity related to restricted stock unit awards during the nine months ended September 30, 2024 is summarized in the following table:

| Service Condition Vesting RSUs |  | Market Plus Service Condition Vesting RSUs
Outstanding at December 31, 2023 | 144,487 |  |  | 123,102 |
RSUs granted | 86,036 |  |  | 56,516 |
RSUs added through dividend and performance credits | 4,685 |  |  | 1,536 |
RSUs released | (69,043) |  |  | (32,248) |
RSUs forfeited | (4,001) |  |  | (2,458) |
Outstanding at September 30, 2024 | 162,164 |  |  | 146,448 |

The 162,164 of service condition vesting RSUs outstanding as of September 30, 2024 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 162,164 of service condition vesting RSUs outstanding as of September 30, 2024 are expected to vest, and be released, on a weighted-average basis, over the next 1.7 years. The Company expects to recognize $4.4 million of pre-tax compensation costs related to these service condition vesting RSUs between September 30, 2024 and their vesting dates. The Company did not modify any service condition vesting RSUs during the nine months ended September 30, 2024 or 2023.
The 146,448 of market plus service condition vesting RSUs outstanding as of September 30, 2024 are expected to vest, and be released, on a weighted-average basis, over the next 1.8 years. The Company expects to recognize $2.3 million of pre-tax compensation costs related to these RSUs between September 30, 2024 and their vesting dates. As of September 30, 2024, 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 219,672 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 nine months ended September 30, 2024 or 2023.

Note 14 – Comprehensive Income (Loss)
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 accumulated other comprehensive income (AOCI), such items, along with net income, are components of other comprehensive income (loss) (OCI).
The components of other comprehensive income (loss) and related tax effects 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.
Individually evaluated 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
35

Table of Contents
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):

Fair value at September 30, 2024 | Total |  | Level 1 |  | Level 2 |  | Level 3

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 nine months ended September 30, 2024 or September 30, 2023, 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):

Three months ended September 30, | Beginning Balance |  | Transfers into (out of) Level 3 |  | Change Included in Earnings |  | Issuances |  | Ending Balance

2024: Mortgage servicing rights | $ | 6,606 |  |  | — |  |  | $ | (468) |  |  | $ | 382 |  |  | $ | 6,520 |
2023: Mortgage servicing rights | $ | 6,712 |  |  | — |  |  | $ | (215) |  |  | $ | 295 |  |  | $ | 6,792 |

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 September 30, 2024 and December 31, 2023:

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 amount 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
37

Table of Contents
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.

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 September 30, 2024 and December 31, 2023 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 September 30, 2024 and December 31, 2023 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 September 30, 2024 and December 31, 2023, capital levels at the Company and the Bank exceed all capital adequacy requirements under the Basel III Capital Rules. Also, at September 30, 2024 and December 31, 2023, 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 for 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 September 30, 2024, the Company and the Bank are in compliance with the capital conservation buffer requirement.

The statements contained herein that are not historical facts are forward-looking statements based on management’s current expectations and beliefs concerning future developments and their potential effects on the Company. Such statements involve inherent risks and uncertainties, many of which are difficult to predict and are generally beyond our control. We caution readers that a number of important factors could cause actual results to differ materially from those expressed in, or implied or projected by, such forward-looking statements. These risks and uncertainties include, but are not limited to, the following: the conditions of the United States economy in general and the strength of the local economies in which we conduct operations; the impact of any future federal government shutdown and uncertainty regarding the federal government’s debt limit or changes in trade, monetary and fiscal policies and laws, including interest rate policies of the Board of Governors of the Federal Reserve System; the impacts of inflation, interest rate, market and monetary fluctuations on the Company's business condition and financial operating results; the impact of changes in financial services industry policies, laws and regulations; regulatory restrictions affecting our ability to successfully market and price our products to consumers; the risks related to the development, implementation, use and management of emerging technologies, including artificial intelligence and machine learning;

the availability of, and cost of, sources of funding and the demand for our products; adverse developments with respect to U.S. or global economic conditions and other uncertainties, including the impact of supply chain disruptions, commodities prices, inflationary pressures and labor shortages on the economic recovery and our business; the impacts of international hostilities, wars, terrorism or geopolitical events; adverse developments in the financial services industry generally such as the recent bank failures and any related impact on depositor behavior or investor sentiment; risks related to the sufficiency of liquidity; the possibility that our recorded goodwill could become impaired, which may have an adverse impact on our earnings and capital; the costs or effects of mergers, acquisitions or dispositions we may make, as well as whether we are able to obtain any required governmental approvals in connection with any such activities, or identify and complete favorable transactions in the future, and/or realize the anticipated financial and business benefits; the regulatory and financial impacts associated with exceeding $10 billion in total assets; the negative impact on our reputation and profitability in the event customers experience economic harm or in the event that regulatory violations are identified; the ability to execute our business plan in new markets; the future operating or financial performance of the Company, including our outlook for future growth and changes in the level and direction of our nonperforming assets and charge-offs; the appropriateness of the allowance for credit losses, including the assumptions made under our current expected credit losses model; any deterioration in values of California real estate, both residential and commercial; the effectiveness of the Company's asset management activities managing the mix of earning assets and in improving, resolving or liquidating lower-quality assets; the effect of changes in the financial performance and/or condition of our borrowers; changes in accounting standards and practices; changes in consumer spending, borrowing and savings habits; our ability to attract and maintain deposits and other sources of liquidity; the effects of changes in the level or cost of checking or savings account deposits on our funding costs and net interest margin; increasing noninterest expense and its impact on our financial performance; competition and innovation with respect to financial products and services by banks, financial institutions and non-traditional competitors including retail businesses and technology companies; the challenges of attracting, integrating and retaining key employees; the vulnerability of the Company's operational or security systems or infrastructure, the systems of third-party vendors or other service providers with whom the Company contracts, and the Company's customers to unauthorized access, computer viruses, phishing schemes, spam attacks, human error, natural disasters, power loss and data/security breaches and the cost to defend against and respond to such incidents; the impact of the 2023 cyber security ransomware incident, including the pending litigation, on our operations and reputation; increased data security risks due to work from home arrangements and email vulnerability; failure to safeguard personal information, and any resulting litigation; the effect of a fall in stock market prices on our brokerage and wealth management businesses; the transition from the LIBOR to new interest rate benchmarks; the emergence or continuation of widespread health emergencies or pandemics; the Company’s potential judgments, orders, settlements, penalties, fines and reputational damage resulting from pending or future litigation and regulatory investigations, proceedings and enforcement actions; and our ability to manage the risks involved in the foregoing. There can be no assurance that future developments affecting us will be the same as those anticipated by management. Additional factors that could cause results to differ materially from those described above can be found in our Annual Report on Form 10-K for the year ended December 31, 2023, which has been filed with the Securities and Exchange Commission (the “SEC”) and all subsequent filings with the SEC under Sections 13(a), 13(c), 14, and 15(d) of the Securities Act of 1934, as amended.

We undertake no obligation (and expressly disclaim any such obligation) to update or alter our forward-looking statements, whether as a result of new information, future events, or otherwise, except as required by law.
General
As TriCo Bancshares (referred to in this report as “we”, “our” or the “Company”) has not commenced any business operations independent of Tri Counties Bank (the “Bank”), the following discussion pertains primarily to the Bank. Average balances, including such balances used in calculating certain financial ratios, are generally comprised of average daily balances for the Company. Within Management’s Discussion and Analysis of Financial Condition and Results of Operations, interest income, net interest income, and net interest yield are generally presented on a FTE basis. The Company believes the use of these non-generally accepted accounting principles (non-GAAP) measures provides additional clarity in assessing its results, and the presentation of these measures on a FTE basis is a common practice within the banking industry. Interest income and net interest income are shown on a non-FTE basis in the Part I - Financial Information section of this Form 10-Q, and a reconciliation of the FTE and non-FTE presentations is provided below in the discussion of net interest income.

Critical Accounting Policies and Estimates
The Company’s discussion and analysis of its financial condition and results of operations are based upon the Company’s consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, the Company evaluates its estimates, including those that materially affect the financial statements and are related to the adequacy of the allowance for loan losses, investments, mortgage servicing rights, fair value measurements, retirement plans and intangible assets. 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. A detailed discussion related to the Company’s accounting policies including those related to estimates on the allowance for credit losses related to loans and investment securities, and impairment of intangible assets, can be found in Note 1 of the consolidated financial statements included in the Company’s annual report on Form 10-K for the year ended December 31, 2023.

(1)Certain information included herein is presented on a FTE basis and/or to present additional financial details which may be desired by users of this financial information. The Company believes the use of this non-generally accepted accounting principles (non-GAAP) measure provides additional clarity in assessing its results, and the presentation of these measures is a common practice within the banking industry.
Loans may be acquired at a premium or discount to par value, in which case, the premium is amortized (subtracted from) or the discount is accreted (added to) interest income over the remaining life of the loan. The dollar impact of loan discount accretion and loan premium amortization decrease as the purchased loans mature or pay off early. Upon the early pay off of a loan, any remaining unaccreted discount or unamortized premium is immediately taken into interest income; and as loan payoffs may vary significantly from quarter to quarter, so may the impact of discount accretion and premium amortization on interest income. Despite the elevated rate environment, the prepayment rate of portfolio loans, inclusive of those acquired at a premium or discount, remains generally consistent. During the quarters ended September 30, 2024, June 30, 2024 and September 30, 2023, the purchased loan discount accretion was $1.0 million, $0.9 million and $1.3 million, respectively.

(2)Net interest spread represents the average yield earned on interest-earning assets minus the average rate paid on interest-bearing liabilities.
(3)Net interest margin is computed by calculating the difference between interest income and interest expense, divided by the average balance of i nterest-earning assets, then annualized based on the number of days in the given period.
Net interest income (FTE) during the three months ended September 30, 2024, decreased $5.6 million or 6% to $82.9 million compared to $88.5 million during the three months ended September 30, 2023. In addition, net interest margin declined 17 basis points to 3.71%, compared to the same quarter last year. The decrease in net interest income is primarily attributed to an additional $13.3 million in deposit interest expense due to rate increases associated with competitive pricing pressures, and to a lesser extent, changes in product mix. The cost of interest-bearing deposits increased by 87 basis points between the quarter ended September 30, 2024 and the same quarter of the prior year. In addition, the average balance of noninterest-bearing deposits decreased by $423.0 million from the three month average for the period ended September 30, 2023 as customers continued to migrate towards higher yielding term deposit accounts. As of September 30, 2024, the ratio of average total noninterest-bearing deposits to total average deposits was 31.7%, as compared to 32.0% and 36.9% at June 30, 2024 and September 30, 2023, respectively. The increase in cost of interest bearing liabilities was partially offset by increased interest and fee income on loans totaling $6.4 million compared to the same quarter of the prior year. Average loan yields increased 32 basis points from 5.51% during the three months ended September 30, 2023, to 5.83% during the three months ended September 30, 2024. The accretion of discounts from acquired loans added 6 and 8 basis points to loan yields during the quarters ended September 30, 2024 and 2023, respectively. Additionally, the average balance of loans during the quarter increased $92.9 million compared to the same period in the prior year.

Net interest income (FTE) during the nine months ended September 30, 2024, decreased $23.1 million, or 9%, to $248.2 million compared to $271.2 million during the nine months ended September 30, 2023. In addition, net interest margin declined 32 basis points to 3.69%, compared to the same period in the prior year. The decrease in net interest income is primarily attributed to an increased cost of interest bearing liabilities, primarily on deposits. The cost of interest bearing deposits increased by 115 basis points during the nine months ended September 30, 2024, compared to the same period in the prior year. In addition, the average balance of noninterest-bearing deposits decreased by $569.1 million from the nine month average for the period ended September 30, 2023 amidst a continued migration of customer funds to interest-bearing products, as discussed above. The increases in the cost of interest bearing liabilities were partially offset by increased interest and fee income on loans. As compared to the same period in the prior year, the average balance of loans increased $262.3 million and average loan yields increased 42 basis points from 5.37% during the nine months ended September 30, 2023, to 5.79% during the nine months ended September 30, 2024. The accretion of discounts from acquired loans added 6 and 9 basis points to loan yields during the nine months ended September 30, 2024 and September 30, 2023, respectively.

The following commentary regarding net interest income, interest income and interest expense may be best understood while referencing the Summary of Average Balances, Yields/Rates and Interest Differential and the Summary of Changes in Interest Income and Expense due to Changes in Average Asset and Liability Balances and Yields Earned and Rates Paid shown above.
Net interest income (FTE) during the three months ended September 30, 2024 decreased $5.6 million to $82.9 million compared to $88.5 million during the three months ended September 30, 2023. The overall decrease in net interest income (FTE) was due to increasing interest rates elevating interest expense on interest-bearing liabilities, most significantly deposits. Elevated interest rates also improved interest income on earning assets by $4.8 million, partially offsetting the increases in interest expense.

Net interest income (FTE) during the nine months ended September 30, 2024 decreased $23.1 million to $248.2 million compared to $271.2 million during the nine months ended September 30, 2023. The overall decrease in net interest income (FTE) was due to increasing interest rates elevating interest expense on interest-bearing liabilities, most significantly deposits and other borrowings, resulting in a net increase of $49.3 million and $0.3 million, respectively. Elevated interest rates also improved interest income on earning assets by $27.0 million, partially offsetting the increases in interest expense.
Asset Quality and Credit Loss Provisioning
During the three months ended September 30, 2024, the Company recorded a provision for credit losses of $0.2 million, as compared to $0.4 million during the trailing quarter, and $4.2 million during the third quarter of 2023.

The allowance for credit losses (ACL) was $123.8 million or 1.85% of total loans as of September 30, 2024. The Company utilizes a forecast period of approximately eight quarters and obtains the forecast data from publicly available sources as of the balance sheet date. This forecast data continues to evolve and includes improving shifts in the magnitude of changes for both the unemployment and GDP factors leading up to the balance sheet date. Core inflation is slowing but prices remain elevated relative to wage increases, as reflected by higher living costs such as housing, energy and general services. Actions by the Federal Reserve to cut rates during 2024 and beyond may help improve this outlook overall, but the uncertainty associated with the extent and timing of these potential reductions has inhibited a material change to forecasted reserve levels. Furthermore, geopolitical risks remain elevated and appear to be getting worse, which may lead to further negative effects on domestic economic outcomes. As a result, management continues to believe that certain credit weaknesses are present in the overall economy and that it is appropriate to maintain a reserve level that incorporates such risk factors.
Loans past due 30 days or more increased by $7.5 million during the quarter ended September 30, 2024, to $37.9 million, as compared to $30.4 million at June 30, 2024. The majority of loans identified as past due are well-secured by collateral, and approximately $16.3 million is less than 90 days delinquent. Non-performing loans were $41.6 million at September 30, 2024, an increase of $8.9 million from $32.8 million as of June 30, 2024, and an increase of $11.8 million from $29.8 million as of September 30, 2023. Management continues to proactively work with these borrowers to identify actionable and appropriate resolution strategies which are customary for the industries. Of the $41.6 million loans designated as non-performing as of September 30, 2024, approximately $10.0 million are current or less than 30 days past due with respect to payments required under their existing loan agreements.

The ratio of classified loans to total loans of 1.76% as of September 30, 2024, increased 20 basis points from June 30, 2024, and increased 55 basis points from the comparative quarter ended 2023. The change in classified loans outstanding as compared to the trailing quarter totaled $16.1 million. Loans with the risk grade classification substandard increased by $12.7 million over the trailing quarter and relate primarily to the commercial and industrial portfolio. As a percentage of total loans outstanding, classified assets remain consistent with volumes experienced prior to the recent quantitative easing cycle spurred by the COVID pandemic and reflect management's historically conservative approach to credit risk monitoring. The Company's combined criticized loan balances totaled $222.4 million as of September 30, 2024, an increase of $46.2 million from September 30, 2023.
Outstanding balances on construction loans, which have historically been associated with elevated levels of risk, experienced balance reductions of $7.3 million during the current quarter and $44.9 million since September 30, 2023. These reductions were primarily associated with balances that were converted to term loans upon the completion of construction and achievement of stabilized occupancy, and were partially offset by new draws or originations.

Total non-interest expense increased $1.4 million or 0.8% to $174.3 million during the nine months ended September 30, 2024, as compared to $172.9 million for the nine months ended September 30, 2023. This was largely attributed to an increase of $3.5 million or 3.5% in total salaries and benefits expense to $105.3 million, from annual compensation adjustments and other routine increases in benefits and compensation. Salaries expense was also impacted by an increase in average compensation per employee as various strategic talent acquisitions were made in order to further prepare the Company to execute its growth objectives beyond $10 billion in total assets. Additionally, data processing and software expenses increased by $1.5 million or 11.1% related to ongoing investments in the Company's data management and security infrastructure. These increases were partially offset by declines in non-cash intangible amortization expense of $1.8 million or 37.0% and reductions in operational losses of $0.8 million or 40.0% due to non-recurring ATM burglary expenses totaling $0.7 million in the comparative period.
Income Taxes
The Company’s effective tax rate was 26.3% and 26.1% for the quarter and nine months ended September 30, 2024, respectively as compared to 27.3% and 26.7% for the comparative periods ended September 30, 2023, respectively. Differences between the Company's effective tax rate and applicable federal and state blended statutory rate of approximately 29.6% are due to the proportion of non-taxable revenues, non-deductible expenses, and benefits from tax credits as compared to the levels of pre-tax earnings.
Financial Condition
For financial reporting purposes, the Company does not separately track the changes in assets and liabilities based on branch location or regional geography. The following is a comparison of the quarterly change in certain assets and liabilities:

Table of Contents
Loans outstanding decreased by $58.6 million or 3.5% on an annualized basis during the quarter ended September 30, 2024. During the quarter, loan originations/draws totaled approximately $310.1 million while payoffs/repayments of loans totaled $368.7 million, which compares to originations/draws and payoffs/repayments during the trailing quarter ended of $325.5 million and $321.3 million, respectively. Origination volume activity levels remain slightly lower relative to the comparative period in 2023 due in part to disciplined pricing and underwriting, as well as decreased borrower demand given economic uncertainties. The increase in payoffs/repayments as compared to the trailing quarter was spread amongst numerous borrowers, regions and loan types.
Investment security balances decreased $30.4 million or 5.8% on an annualized basis during the current quarter as a result of net prepayments, and maturities, collectively totaling approximating $164.0 million and, to a lesser extent, sales totaling $28.6 million, partially offset by security purchases totaling $53.5 million, in addition to net increases in the market value of securities of $4.1 million. Investment security purchases were comprised of floating rate instruments tied to SOFR with an initial weighted average coupon of 6.77% and a weighted average life of 4.7 years. Investment security sales were primarily comprised of fixed rate instruments with a weighted average coupon of 2.39% and a weighted average life of 3.8 years. While management intends to primarily utilize cash flows from the investment security portfolio and organic deposit growth to support loan growth, excess liquidity will be utilized for purchases of investment securities to support net interest income growth and net interest margin expansion.
Deposit balances increased by $13.1 million or 0.7% annualized during the quarter, led by growth within time deposits.
Other borrowings totaled $266.8 million at September 30, 2024, representing a net decrease of $19.0 million from the trailing quarter. This quarter over quarter decrease was facilitated by proceeds from the sale, call or maturity of investment securities, and growth in deposits.
The following is a comparison of the year over year change in certain assets and liabilities:

Loans
The Company focuses its primary lending activities in six principal areas: commercial real estate loans, consumer loans, commercial and industrial loans, construction loans, agriculture production loans and leases. The interest rates charged for the loans made by the Company vary with the degree of risk, the size and duration of the loans, the borrower’s relationship with the Company and prevailing money market rates indicative of the Company’s cost of funds.
The majority of the Company’s loans are direct loans made to individuals, and local or regional businesses which service a variety of industries. The Company relies substantially on local promotional activity and personal contacts by bank officers, directors and employees to compete with other financial institutions. The Company makes loans to borrowers whose applications include a sound purpose, a viable repayment source and a plan of repayment established at inception and generally backed by a secondary source of repayment.

Loan charge-offs during the three and nine months ended September 30, 2024
In the third quarter of 2024, the Company recorded $0.4 million in loan charge-offs and $0.1 million in deposit overdraft charge-offs less $0.3 million in loan recoveries and $0.02 million in deposit overdraft recoveries, which collectively resulted in $0.1 million in net charge-offs. During the nine months ended September 30, 2024, the Company recorded $3.3 million in loan charge-offs and $0.2 million in deposit overdraft charge-offs less $0.9 million in loan recoveries and $0.1 million in deposit overdraft recoveries, which collectively resulted in $3.0 million in net charge-offs.

For additional information regarding the allowance for loan losses, including changes in specific, formula, and environmental factors allowance categories, see “Asset Quality and Loan Loss Provisioning” at “Results of Operations”, above. Based on the current conditions of the loan portfolio, management believes that the $123.8 million allowance for loan losses at September 30, 2024 is adequate to absorb probable losses inherent in the Bank’s loan portfolio. No assurance can be given, however, that adverse economic conditions or other circumstances will not result in increased losses in the portfolio.

There were no brokered deposits included in the deposit balances as of September 30, 2024 and December 31, 2023. Estimated uninsured deposits totaled $2.5 billion and $2.4 billion as of September 30, 2024 and December 31, 2023, respectively.
Off-Balance Sheet Arrangements
See Note 9 to the condensed consolidated financial statements at Item 1 of Part I of this report for information about the Company’s commitments and contingencies including off-balance-sheet arrangements.
Capital Resources
The current and projected capital position of the Company and the impact of capital plans and long-term strategies are reviewed regularly by Management.
On February 25, 2021 the Board of Directors authorized the repurchase of up to 2,000,000 shares of the Company's common stock (the 2021 Repurchase Plan), which approximated 6.7% of the shares outstanding as of the approval date. 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 2021 Repurchase Plan is subject to change. The Company may repurchase its outstanding shares of common stock from time to time in open market or privately-negotiated transactions, including block trades, or pursuant to 10b5-1 trading plans. The 2021 Repurchase Plan has no expiration date (in accordance with applicable laws and regulations).
During the three and nine months ended September 30, 2024, the Company repurchased zero and 344,324 shares with market values of $0.0 million and $12.5 million, respectively. During the three and nine months ended September 30, 2023, the Company repurchased zero and 150,000 shares with market values of zero and $7.0 million, respectively. In addition, the Company’s Tier 1 common equity and tangible capital ratios increased to 13.1% and 9.7%, respectively as of September 30, 2024, compared to 12.2% and 8.8%, respectively, as of December 31, 2023.
Total shareholders' equity increased by $64.0 million during the quarter ended September 30, 2024, as net income of $29.1 million and a $44.5 million decrease in accumulated other comprehensive losses was partially offset by cash dividend payments on common stock of approximately $10.9 million. As a result, the Company’s book value grew to $37.55 per share at September 30, 2024, compared to $32.18 at September 30, 2023. The Company’s tangible book value per share, a non-GAAP measure, calculated by subtracting goodwill and other intangible assets from total shareholders’ equity and dividing that sum by total shares outstanding, was $28.09 per share at September 30, 2024, as compared to $22.67 at September 30, 2023. As noted previously, changes in the fair value of available-for-sale investment securities, net of deferred taxes continue to create moderate levels of volatility in tangible book value per share.

Our ability to issue securities is subject to market conditions and other factors including, in the case of our debt securities, our credit ratings and compliance with current and prospective covenants in credit agreements.
Liquidity
The Company's primary sources of liquidity include the following for the periods indicated:

(dollars in thousands) | September 30, 2024 |  | December 31, 2023 |  |
Borrowing capacity at correspondent banks and FRB | $ | 2,757,640 |  |  | $ | 2,921,525 |  |  |

Total primary liquidity | $ | 4,095,293 |  |  | $ | 3,931,284 |  |  |

At September 30, 2024, the Company's primary sources of liquidity represented 51% of total deposits and 163% of estimated total uninsured (excluding collateralized municipal deposits and intercompany balances) deposits, respectively. As secondary sources of liquidity, the Company's held-to-maturity investment securities had a fair value of $112.0 million, including approximately $5.3 million in net unrealized losses.
The Company’s profitability during the first nine months of 2024 generated cash flows from operations of $85.5 million compared to $102.4 million during the first nine months of 2023. Net cash from investing activities was $345.0 million for the nine months ended September 30, 2024, compared to net cash from investing activities of $13.6 million during the nine months ending 2023. Financing activities used $209.0 million during the nine months ended September 30, 2024, compared to $84.9 million during the nine months ended September 30, 2023.
The changes in contractual obligations of the Company and Bank, to include but not limited to term subordinated debt, operating leases, deferred compensation and supplemental retirement plans as well as off-balance sheet commitments such as unfunded loans and letters of credit, are consistent with similar balances or totals as of December 31, 2023.
The Company is dependent upon the payment of cash dividends by the Bank to service its commitments, which have historically included dividends to shareholders, scheduled debt service payments, and general operations. Shareholder dividends are expected to continue subject to the Board’s discretion and management's continuing evaluation of capital levels, earnings, asset quality and other factors. The Company expects that the cash dividends paid by the Bank to the Company will be sufficient to cover the Company's cash flow needs. However, the Company and its ability to generate liquidity through either the issuance of stock or debt, also serves as a potential source of strength for the Bank. Dividends paid by the Company to holders of its common stock used $32.8 million and $29.9 million of cash during the nine months ended September 30, 2024 and 2023, respectively. The Company’s liquidity is dependent on dividends received from the Bank. Dividends from the Bank are subject to certain regulatory restrictions.

TRICO BANCSHARES—NON-GAAP FINANCIAL MEASURES
(Unaudited. Dollars in thousands)
In addition to results presented in accordance with generally accepted accounting principles in the United States of America (GAAP), this filing contains certain non-GAAP financial measures. Management has presented these non-GAAP financial measures in this filing because it believes that they provide useful and comparative information to assess trends in the Company's core operations reflected in the current quarter's results, and facilitate the comparison of our performance with the performance of our peers. However, these non-GAAP financial measures are supplemental and are not a substitute for any analysis based on GAAP. Where applicable, comparable earnings information using GAAP financial measures is also presented. Because not all companies use the same calculations, our presentation may not be comparable to other similarly titled measures as calculated by other companies. For a reconciliation of these non-GAAP financial measures, see the tables below:

Item 3. Quantitative and Qualitative Disclosures about Market Risk
Based on the changes in interest rates as well as the mix shift of interest earning assets and interest bearing liabilities occurring subsequent to December 31, 2023, the following update of the Company’s assessment of market risk as of September 30, 2024 is being provided. These updates and changes should be read in conjunction with the additional quantitative and qualitative disclosures in our Annual Report on Form 10-K for the year ended December 31, 2023.
As of September 30, 2024, the Company's loan portfolio consisted of approximately $6.7 billion in outstanding principal with a weighted average coupon rate of 5.49%. During the three-month periods ending September 30, 2024, June 30, 2024, and September 30, 2023, the weighted average coupon on loan production in the quarter was 7.63%, 7.98% and 7.31%, respectively. Included in the September 30, 2024, total loans are adjustable rate loans totaling $4.2 billion, of which, $891.6 million are considered floating based on the Wall Street Prime index. In addition, the Company holds certain investment securities with fair values totaling $371.1 million which are subject to repricing on not less than a quarterly basis.
Management funds the acquisition of nearly all of its earning assets through its core deposit gathering activities. As of September 30, 2024, non-interest bearing deposits represented 31.7% of total deposits. Further, during the quarter ended September 30, 2024, the cost of interest bearing deposits were 2.23% and the cost of total deposits were 1.52%. With the intent of stabilizing or increasing net interest income, management intends to continue to deploy its excess liquidity and/or seek to migrate certain earning assets into higher yielding categories. However, in situations where deposit balances contract, management may rely upon various borrowing facilities or the use of brokered deposits. Through the third quarter of 2024 and during the entire 2023 year, management did not utilize any brokered deposits. Management did however utilize borrowing lines from the FHLB, both overnight and term structured up to 12 months, due to expectations that such borrowings will be needed through the remainder of the year and into 2025 to support earning asset strategies.
As of September 30, 2024 the overnight Federal funds effective rate, the rate primarily used in these interest rate shock scenarios, was 4.83%. These scenarios assume that 1) interest rates increase or decrease evenly (in a “ramp” fashion) over a twelve-month period and remain at the new levels beyond twelve months or 2) that interest rates change instantaneously (“shock”). The simulation results shown below assume no changes in the structure of the Company’s balance sheet over the twelve months being measured.
The following table summarizes the estimated effect on net interest income and market value of equity to changing interest rates as measured against a flat rate (no interest rate change) instantaneous parallel shock scenario over a twelve month period utilizing a interest sensitivity (GAP) analysis based on the Company's specific mix of interest earning assets and interest bearing liabilities as of September 30, 2024.
Interest Rate Risk Simulations:

Change in Interest Rates (Basis Points) | Estimated Change in Net Interest Income (NII) (as % of NII) |  | Estimated Change in Market Value of Equity (MVE) (as % of MVE)
+300 (shock) | (7.4) | % |  | (5.6) | %
+200 (shock) | (5.0) | % |  | (3.7) | %
+100 (shock) | (2.4) | % |  | (0.8) | %
+ 0 (flat) | — |  |  | — |
-100 (shock) | 0.2 | % |  | (2.8) | %
-200 (shock) | 0.1 | % |  | (9.6) | %
-300 (shock) | 1.5 | % |  | (20.8) | %

Item 4. Controls and Procedures
The Company’s management, including its Chief Executive Officer and Chief Financial Officer, have evaluated the effectiveness of the Company’s disclosure controls and procedures as of September 30, 2024. Disclosure controls and procedures, as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), are controls and procedures designed to reasonably assure that information required to be disclosed in the Company’s reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported on a timely basis. Disclosure controls are also designed to reasonably assure that such information is accumulated and communicated to the Company’s management, including the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Based upon their evaluation, our Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective as of September 30, 2024.
During the three months ended September 30, 2024, there were no changes in our internal controls or in other factors that have materially affected or are reasonably likely to materially affect our internal controls over financial reporting.

Item 5 — Other Information
Rule 10b5-1 Trading Arrangements
(a) TriCo Bancshares (the “Company”) adopted a form of Restricted Stock Unit Award Agreement (the “RSU Agreement”) and a form of Performance Award Agreement (the “PSU Agreement”) to be used to document grants of awards to executives made under the 2019 Equity Incentive Plan (the “Plan”) during 2024. The agreements were signed by the executives on November 6, 2024.
The RSU Agreement provides that awards of restricted stock units (“RSUs”) vest in three equal annual installments. RSUs vest automatically upon a recipient’s employment termination due to death or disability.
The PSU Agreement provides that performance stock units (“PSUs”) vest in a single tranche three years after the grant date. The number of PSUs earned upon vesting depends on the total shareholder return for the Company’s common stock relative to the KBW Nasdaq Regional Banking Index over a three-year performance period beginning on the date of grant. The actual number of shares earned on vesting ranges from 0% to 150% of the target number granted, depending on the performance of the Company’s common stock compared to the index over the performance period. Upon a recipient’s employment termination due to death or disability, the final day of the performance period will be adjusted to be the executive’s termination date and a pro rata portion of the PSUs will vest based on the portion of the original three-year performance period elapsed. In the event of a change of control, the performance period will be adjusted to end the day immediately prior to the change of control and a pro rata portion of the PSUs will vest based on the portion of the original three-year performance period elapsed, provided that if the recipient is terminated within 12 months of the date of the change of control, the recipient shall instead be entitled to 100% of the number of PSU determined as of the end of the adjusted performance period.
The RSU Agreement and PSU Agreement further provide that if an executive recipient having at least six full years of service with the Company retires from employment at age 62 or greater, a percentage of the outstanding and unvested equity awards granted by the Company pursuant to these agreements will continue to vest following retirement, subject to certain conditions, including that (1) the participant provides at least 9 months written notice of their intent to retire, (2) the Company determines that the continued vesting is appropriate, based on the recipient’s performance and (3) the recipient executes of a release of claims in favor of the Company. The percentage of the awards entitled to post-retirement vesting is based on the number of full years of service with the Company that participant has completed at retirement and ranges from 20% (with six full years of service) to 100% (with 10 or more full years of service),
64

Table of Contents
provided that if the Company’s pre-tax, pre-provision income is negative for any of the four quarters immediately preceding the participant’s retirement, the number of awards entitled to post-retirement vesting will be reduced by 25%.
This summary of the RSU Agreement and the PSU Agreement does not purport to be complete and is qualified in its entirety by reference to the forms such agreements filed as exhibits to this report. Form of these agreements are included as exhibits 10.2 and 10.4 to this Form 10-Q.
(b) N/A
(c) During the three and nine months ended September 30, 2024, none of the Company’s directors or officers (as defined in Rule 16a-1(f)) adopted or terminated a Rule 10b5-1 trading arrangement or non-Rule 10b5-1 trading arrangement (in each case, as defined in item 408 of Regulation S-K) for the purchase or sale of the Company's common stock.
