CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

In addition to historical information, this Annual Report on Form 10-K contains forward-looking statements about TriCo Bancshares (the “Company,” “TriCo” or “we”) and its subsidiaries for which it claims the protection of the safe harbor provisions contained in the Private Securities Litigation Reform Act of 1995. These forward-looking statements are based on the current knowledge and belief of the Company’s management (“Management”) and include information concerning the Company’s possible or assumed future financial condition and results of operations. When you see any of the words “believes”, “expects”, “anticipates”, “estimates”, or similar expressions, these generally indicate that we are making forward-looking statements. A number of factors, some of which are beyond the Company’s ability to predict or control, could cause future results to differ materially from those contemplated.

Forward looking statements involve inherent risks and uncertainties, many of which are difficult to predict and are generally beyond our control. There can be no assurance that future developments affecting us will be the same as those anticipated by management. 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 strength of the United States economy in general and the strength of the local economies in which we conduct operations; the effects of, and changes in, trade, monetary and fiscal policies and laws, including interest rate policies of the Board of Governors of the Federal Reserve System; inflation, interest rate, market and monetary fluctuations impacts on our business condition and financial operating results; the impact of changes in financial services industry policies, laws and regulations; regulatory restrictions on our ability to successfully market and price our products to consumers; technological changes; weather, natural disasters, climate change and other catastrophic events and their effects on economic and business environments in we operate; the continuing adverse impact on the U.S. economy, including the markets in which we operate due to the COVID-19 global pandemic; the impact of a slowing U.S. economy and increased unemployment on the performance of our loan portfolio, the market value of our investment securities, the availability 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, terrorism or geopolitical events; 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 mergers, acquisitions or dispositions, identify and complete favorable transactions in the future, and/or realize the contemplated financial business benefits associated with any such activities; 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 lending 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 effects of the implementation of the 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 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; possible other-than-temporary impairment of securities held by us due to changes in credit quality or rates; 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; our noninterest expense and the efficiency ratio; competition and innovation with respect to financial products and services by banks, financial institutions and non-traditional providers including retail businesses and technology companies; the challenges of attracting, integrating and retaining key employees; the costs and effects of litigation and of unexpected or adverse outcomes in such litigation; the vulnerability of the Company's operational or security systems, networks 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 remediate such incidents; increased data security risks due to work from home arrangements; failure to safeguard personal information; changes to U.S. tax policies, including our effective income tax rate; the effect of a fall or volatility in stock market prices on our brokerage and wealth management businesses; the transition away from LIBOR toward new interest rate benchmarks; and our ability to manage the risks involved in the foregoing. See also factors listed at Item 1A Risk Factors, in this report.

Annualized, pro forma, projections and estimates are not forecasts and may not reflect actual results. All forward-looking statements speak only as of the date they are made and are based on information available at that time. Forward-looking statements speak only as of the date they are made, and the Company does not undertake to update forward-looking statements to reflect circumstances or events that occur after the date the forward-looking statements are made, whether as a result of new information, future developments or otherwise, except as required by federal securities laws. As forward-looking statements involve significant risks and uncertainties, caution should be exercised against placing undue reliance on such statements.

PART I

ITEM 1.    BUSINESS

Overview

TriCo Bancshares is a registered bank holding company under the Bank Holding Company Act of 1956, as amended (the “BHC Act”). TriCo's principal business is to serve as the holding company for our wholly-owned subsidiary, Tri Counties Bank, a California-chartered commercial bank (the “Bank”). TriCo is a California corporation and was incorporated in 1981. Our common stock is traded on the Nasdaq Global Select Market under the trading symbol "TCBK". The Company and the Bank are headquartered in Chico, California.

As a bank holding company, TriCo is subject to the supervision of the Board of Governors of the Federal Reserve System (the “FRB”) under the BHC Act. The Bank is subject to the supervision of the California Department of Financial Protection & Innovation (the “DFPI”) and the Federal Deposit Insurance Corporation (the "FDIC"). See “Regulation and Supervision.”

In addition, TriCo has five capital trusts, which are all wholly-owned trust subsidiaries formed for the purpose of issuing trust preferred securities (“Trust Preferred Securities”) and lending the proceeds to TriCo. For more information regarding the trust preferred securities please refer to “Note 14 – Junior Subordinated Debt” to the financial statements at Item 8 of this report.

Additional Information

Additional information concerning the Company can be found on our website at www.tcbk.com. Copies of our annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and amendments to these reports are available free of charge through the investors relations page of our website, www.tcbk.com/about/investor-relations, as soon as reasonably practicable after the Company files these reports with the U.S. Securities and Exchange Commission (“SEC”). The information on our website is not part this annual report.

Tri Counties Bank

The Bank was organized in 1975 and had total assets of approximately $9.9 billion at December 31, 2022. Based in Chico, California, the Bank offers an extensive and competitive breadth of consumer, small business and commercial banking services through its network of stand-alone and in-store branches in communities throughout California. The Bank focuses on relationships and personal contact, emphasizing its Service with Solutions ®. In addition to its California community bank network, the Bank provides advanced online and mobile banking, a shared nationwide network of over 37,000 ATMs, and bankers available by phone 7 days per week.

The Bank provides a breadth of personal, small business and commercial financial services including accepting demand, savings and time deposits and making small business, commercial, real estate, and consumer loans, as well as a range of Treasury Management Services and other customary banking services including safe deposit boxes at some branches. Brokerage services are provided at the Bank’s offices by Tri Counties Wealth Management Advisors through the Bank’s arrangement with Raymond James Financial Services, Inc., an independent financial services provider and broker-dealer.

The Bank offers a variety of banking and financial services to both personal, small business and commercial customers. In many instances the owners or stakeholders of the business and commercial customers are also personal customers. The industries that we serve are diverse in both number and type and include, but are not limited to, manufacturing, real estate development, retail, wholesale, transportation, agriculture, commerce, and professional services. The majority of the Bank’s loans are direct loans made to individuals and businesses in California where its branches or business lending centers are located. At December 31, 2022, the Bank’s consumer loans net of deferred fees outstanding were $1,240,743,000 (19.2%), commercial and industrial loans outstanding were $569,921,000 (8.8%), real estate construction loans of $211,560,000 (3.3%), and commercial real estate loans were $4,359,083,000 (67.6%) of total loans. The Bank takes real estate, listed and unlisted securities, savings and time deposits, automobiles, machinery, equipment, inventory, accounts receivable and notes receivable secured by property as collateral for loans.

Most of the Bank’s deposits are attracted from individuals and business-related sources. No single person or group of persons provides a material portion of the Bank’s deposits, the loss of any one or more of which would have a materially adverse effect on the business of the Bank, nor is a material portion of the Bank’s loans concentrated within a single industry or group of related industries.

Merger with Valley Republic Bancorp

On March 25, 2022, the Company completed its acquisition of Valley Republic Bancorp, including the merger of Valley Republic Bank into Tri Counties Bank, with Tri Counties Bank as the surviving entity, in accordance with the terms of the merger agreement dated as of July 27, 2021. The cash and stock transaction was valued at approximately $174.0 million in aggregate, based on TriCo's closing stock price of $42.48 on March 25, 2022. Under the terms of the merger agreement, the Company issued approximately 4.1 million shares, in addition to approximately $431,000 in cash paid out for settlement of stock option awards at VRB. VRB was headquartered in Bakersfield, California, and had four branch locations in and around Bakersfield, and a loan production office in Fresno, California. The Bank's overlapping Bakersfield branch was consolidated into the acquired VRB branch during the quarter ended June 30, 2022, and the VRB loan production office in Fresno was consolidated with the nearby legacy TCBK loan production office during the fourth quarter of 2022. All remaining branches now operate as Tri Counties Bank.

Human Capital Resources

At December 31, 2022, we employed 1,231 persons, including five executive officers. Full time equivalent employees numbered 1,210. Additionally, we at times will utilize independent contractors and temporary personnel to supplement our workforce. None of our employees are presently represented by a union or covered under a collective bargaining agreement. Management believes that its employee relations are good.

Our employees are critical to our success and competition for qualified banking personnel has historically been intense. We provide a wide variety of opportunities for professional growth for all employees with a focus on in-classroom and on-line trainings, on-the-job experience, including active mentoring and education tuition assistance. We seek to create an engaged workforce through proactive listening, forward looking career conversation and constructive dialogue through periodic performance discussions as well as employee engagement and exit surveys.

We focus on attracting and retaining employees by providing compensation and benefits packages that we believe are competitive within the applicable market, taking into account the position’s location and responsibilities. We provide competitive health and financial focused benefits such as but not limited to employer subsidized health insurance, a 401(k) retirement plan and an employee stock ownership plan. In addition, we offer a portfolio of additional services and tools to support our employees’ health and well-being.

TriCo team members actively share their talents in their communities through volunteer activities in education, economic development, human and health services, and community reinvestment. During 2022, team members logged more than 10,000 hours, supporting nearly 360 organizations, and more than 3,200 of those hours were for the benefit of community development efforts to support programs and services to low- or moderate-income communities.

While we believe that the diversity of our employees generally represents and reflects the diversity of the communities which we serve, we recognize and continue to promote the need for diversity enhancement in leadership roles throughout the Company. We have assembled a team to assist us in progressing the Bank's diversity, inclusion, and equity efforts. Our efforts to foster an environment that embraces employee perspectives through understanding one another's opinions, beliefs, experiences, innate differences and the promotion of dialogue and actions will make us a stronger company. We also believe that a diverse workforce that is representative of our customers in the community will enable us to better serve our customers, enhancing our success as an organization. We know the process is a journey and expect our efforts to develop and progress over time.

Refer to Item 7: Management’s Discussion and Analysis of Financial Condition and Results of Operations for additional information.

Competition

The banking business in California generally is highly competitive with respect to both loans and deposits. It is dominated by a relatively small number of national and regional banks with many offices operating over a wide geographic area; with the more metropolitan areas that we serve having a larger number of national and regional banks than the rest of our footprint. Among the advantages such major banks have over the Bank are their greater ability to finance investments in technology and marketing campaigns and to allocate their investment assets to regions of high yield and demand. By virtue of their greater total capitalization, such institutions also have substantially higher lending limits than the Bank.

In addition to competing with other banks, the Bank competes with savings institutions, credit unions and the financial markets for funds. Yields on corporate and government debt securities and other commercial paper may be higher than on deposits, and therefore affect the ability of commercial banks to attract and hold deposits. Commercial banks also compete for available funds with money market instruments and mutual funds. During periods of high or rising interest rates, money market funds have provided substantial competition to banks for deposits and they may continue to do so in the future. Mutual funds are also a major source of competition for savings dollars.

As the financial services industry becomes increasingly oriented toward technology-driven delivery systems, we face competition from banks and non-bank institutions without offices in our primary service area. We also increasingly compete with financial technology or “fintech” companies for loans and other financial services customers.

To compete effectively, the Bank relies substantially on local promotional activity, personal contacts by its officers, directors, employees and shareholders, extended hours, personalized service and its reputation in the communities it services.

Regulation and Supervision

General

The Company and the Bank are subject to extensive regulation under both federal and state law governing most aspects of our operations. This regulation is intended primarily for the protection of customers, depositors, the FDIC deposit insurance fund and the banking system as a whole, and not for the protection of shareholders of the Company. Set forth below is a summary description of the significant laws and regulations applicable to the Company and the Bank. The description is qualified in its entirety by reference to the applicable laws and regulations.

Regulatory Agencies

3 TriCo Bancshares 2022 10-K

The Company is a legal entity separate and distinct from the Bank and its other subsidiaries. As a bank holding company, the Company is regulated under the BHC Act, and is subject to supervision, regulation and examination by the FRB. The Company is also under the jurisdiction of the SEC and is subject to the disclosure and regulatory requirements of the Securities Act of 1933 and the Securities Exchange Act of 1934, each administered by the SEC. The Company’s common stock is listed on the Nasdaq Global Select Market (“Nasdaq”) under the trading symbol “TCBK” and the Company is, therefore, subject to the rules of Nasdaq for listed companies.

The Bank is subject to regulation, supervision and periodic examination by the FDIC, which is the Bank’s primary federal regulator and the DFPI.

The Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) created the Consumer Financial Protection Bureau (the “CFPB”) as an independent entity with broad rulemaking, supervisory and enforcement authority over consumer financial products and services. The CFPB’s functions include investigating consumer complaints, rulemaking, supervising and examining bank consumer transactions, and enforcing rules related to consumer financial products and services. CFPB regulations and guidance apply to all financial institutions, including the Bank. Banks with $10 billion or more in assets are subject to examination by the CFPB. Banks with less than $10 billion in assets, including the Bank, continue to be examined for compliance with federal consumer laws by their primary federal banking agency. At December 31, 2022, the Company had $9.9 billion in total assets. See the Risk Factors section for a discussion of some of the risks the Bank will encounter when it exceeds $10 billion in assets as of a December 31 measurement date.

The Bank Holding Company Act

The Company is registered as a bank holding company under the BHC Act. In general, the BHC Act limits the business of bank holding companies to banking, managing or controlling banks and other activities that the FRB has determined to be so closely related to banking as to be a proper incident thereto. Qualified bank holding companies that elect to be financial holding companies may engage in any activity, or acquire and retain the shares of a company engaged in additional activities that are either (i) financial in nature or incidental to such financial activity or (ii) complementary to a financial activity, and do not pose a substantial risk to the safety and soundness of depository institutions or the financial system generally, as determined by the FRB. Activities that are financial in nature include securities underwriting and dealing, insurance underwriting and agency, and making merchant banking investments. The Company currently has not elected to become a financial holding company.

As a bank holding company, TriCo is required to file reports with the FRB and the FRB periodically examines the Company. A bank holding company is required by law to serve as a source of financial and managerial strength to its subsidiary bank and, under appropriate circumstances, to commit resources to support the subsidiary bank.

Bank Acquisitions

We are required to obtain prior FRB approval before acquiring more than 5% of the voting shares, or substantially all of the assets, of a bank holding company, bank or savings association. In addition, the prior approval of the FDIC and DFPI is required for a California chartered bank to merge with another bank or purchase the assets or assume the deposits of another bank. In determining whether to approve a proposed bank acquisition, bank regulators will consider, among other factors, the effect of the acquisition on competition, the public benefits expected to be received from the acquisition, the projected capital ratios and levels on a post-acquisition basis, and the acquiring institution’s record of addressing the credit needs of the communities it serves, including the needs of low- and moderate-income neighborhoods under the Community Reinvestment Act of 1997, as amended ("CRA").

On July 9, 2021, President Biden issued an Executive Order on Promoting Competition in the American Economy. Among other initiatives, the Executive Order encouraged the federal banking agencies to review their current merger oversight practices under the BHC Act and the Bank Merger Act and adopt a plan for revitalization of such practices. There are many steps that must be taken by the agencies before any formal changes to the framework for evaluating bank mergers can be finalized and the prospects for such action are uncertain at this time; however, the adoption of more expansive or prescriptive standards may have an impact on our acquisition activities. See the Risk Factors section for a more extensive discussion of this topic.

Safety and Soundness Standards

Under the Federal Deposit Insurance Corporation Improvement Act of 1991 (“FDICIA”), the federal bank regulatory agencies have established safety and soundness standards for insured depository institutions covering:

•Internal controls, information systems and internal audit systems;

•Loan documentation;

•Credit underwriting;

•Interest rate exposure;

•Asset growth;

•Compensation, fees and benefits;

•Asset quality, earnings and stock valuation; and

•Excessive compensation for executive officers, directors or principal shareholders which could lead to material financial loss.

4 TriCo Bancshares 2022 10-K

If a federal bank regulatory agency determines that a depository institution fails to meet any standard established by the guidelines, the agency may require the institution to submit to the agency an acceptable plan to achieve compliance with the standard. If the agency requires submission of a compliance plan and the institution fails to timely submit an acceptable plan or to implement an accepted plan, the agency must require the institution to correct the deficiency. An institution must file a compliance plan within 30 days of a request to do so from the institution’s primary federal regulatory agency. The agencies may elect to initiate enforcement actions in certain cases rather than relying on a plan, particularly where failure to meet one or more of the standards could threaten the safe and sound operation of the institution.

Restrictions on Dividends and Distributions

A California corporation such as TriCo may make a distribution to its shareholders to the extent that either the corporation’s retained earnings meet or exceed the amount of the proposed distribution or the value of the corporation’s assets exceed the amount of its liabilities plus the amount of shareholders preferences, if any, and certain other conditions are met. It is the FRB’s policy that bank holding companies should generally pay dividends on common stock only out of income available over the past year, and only if prospective earnings retention is consistent with the organization’s expected future needs and financial condition. In addition, a bank holding company’s ability to pay dividends on its common stock may be limited if it fails to maintain an adequate capital conservation buffer under these capital rules. See “Regulatory Capital Requirements.”

The primary source of funds for payment of dividends by TriCo to its shareholders has been and will be the receipt of dividends and management fees from the Bank. TriCo’s ability to receive dividends from the Bank is limited by applicable state and federal law. Under the California Financial Code, funds available for cash dividend payments by a bank are restricted to the lesser of: (i) retained earnings or (ii) the bank’s net income for its last three fiscal years (less any distributions to shareholders made during such period). However, with the prior approval of the Commissioner of the DPFI, a bank may pay cash dividends in an amount not to exceed the greatest of the: (1) retained earnings of the bank; (2) net income of the bank for its last fiscal year; or (3) net income of the bank for its current fiscal year. However, if the DPFI finds that the shareholders’ equity of the bank is not adequate or that the payment of a dividend would be unsafe or unsound, the Commissioner may order the bank not to pay a dividend to shareholders.

The Bank’s ability to pay dividends may be limited if the Bank fails to maintain an adequate capital conservation buffer. See “Regulatory Capital Requirements.”

The FRB, FDIC and the DPFI have authority to prohibit a bank holding company or a bank from engaging in practices which are considered to be unsafe and unsound. Depending on the financial condition of TriCo and the Bank and other factors, our regulators could determine that payment of dividends or other payments by TriCo or the Bank might constitute an unsafe or unsound practice.

The Community Reinvestment Act

The CRA requires the federal banking regulatory agencies to periodically assess a bank’s record of helping meet the credit needs of its entire community, including low- and moderate-income neighborhoods. The CRA also requires the agencies to consider a financial institution’s record of meeting its community credit when evaluating applications for, among other things, domestic branches and mergers or acquisitions. The federal banking agencies rate depository institutions’ compliance with the CRA. The ratings range from a high of “outstanding” to a low of “substantial noncompliance.” A less than “satisfactory” rating could result in the suspension of any growth of the Bank through acquisitions or opening de novo branches until the rating is improved. As of its most recent CRA examination, the Bank’s CRA rating was “Satisfactory."

On May 5, 2022, the FRB, OCC and FDIC jointly issued a notice of proposed rulemaking proposing revisions to the agencies’ CRA regulations, including with respect to the delineation of assessment areas, the overall evaluation framework and performance standards and metrics, the definition of community development activities, and data collection and reporting. The proposed rule would adjust CRA evaluations based on bank size and type, with many of the proposed changes applying only to banks with over $2 billion in assets and several applying only to banks with over $10 billion in assets. We will continue to evaluate the impact of any changes to the regulations implementing the CRA.

Consumer Protection Laws and Supervision

The Bank is subject to many federal consumer protection statues and regulations, some of which are discussed below.

•The Equal Credit Opportunity Act generally prohibits discrimination in any credit transaction, whether for consumer or business purposes, on the basis of race, color, religion, national origin, sex, marital status, age (except in limited circumstances), receipt of income from public assistance programs, or good faith exercise of any rights under the Consumer Credit Protection Act.

•The Truth-in-Lending Act is designed to ensure that credit terms are disclosed in a meaningful way so that consumers may compare credit terms more readily and knowledgeably.

•The Fair Housing Act regulates many practices, including making it unlawful for any lender to discriminate in its housing-related lending activities against any person because of race, color, religion, national origin, sex, handicap or familial status.

•The Home Mortgage Disclosure Act, which includes a “fair lending” aspect, requires the collection and disclosure of data about applicant and borrower characteristics as a way of identifying possible discriminatory lending patterns and enforcing anti-discrimination statutes.

5 TriCo Bancshares 2022 10-K

•The Real Estate Settlement Procedures Act requires lenders to provide borrowers with disclosures regarding the nature and cost of real estate settlements and prohibits certain abusive practices, such as kickbacks, and places limitations on the amount of escrow accounts.

In addition, the CFPB has taken a number of actions that may affect the Bank’s operations and compliance costs, including the following:

•The issuance of final rules for residential mortgage lending, which became effective January 10, 2013, including definitions for “qualified mortgages” and detailed standards by which lenders must satisfy themselves of the borrower’s ability to repay the loan and revised forms of disclosure under the Truth in Lending Act and the Real Estate Settlement Procedures Act.

•Actions taken to regulate and supervise credit bureaus and debt collections.

•Positions taken by the CFPB on fair lending, including applying the disparate impact theory in auto financing, which could make it harder for lenders, such as the Bank, to charge different rates or apply different terms to loans to different customers.

The CFPB has broad rulemaking authority for a wide range of consumer financial laws that apply to all banks, including, among other things, laws relating to fair lending and the authority to prohibit “unfair, deceptive or abusive” acts and practices. The CFPB has promulgated many mortgage-related final rules since it was established under the Dodd-Frank Act, including rules related to the ability to repay and qualified mortgage standards, mortgage servicing standards, loan originator compensation standards, high-cost mortgage requirements, HMDA requirements, and appraisal and escrow standards for higher priced mortgages. The mortgage-related final rules issued by the CFPB have materially restructured the origination, servicing, and securitization of residential mortgages in the United States. These rules have impacted, and will continue to impact, the business practices of mortgage lenders, including the Company.

We are also subject to certain state consumer protection laws and state attorneys general and other state officials are empowered to enforce certain federal consumer protection laws and regulations. State authorities have increased their focus on and enforcement of consumer protection rules. These federal and state consumer protection laws apply to a broad range of our activities and to various aspects of our business and include laws relating to interest rates, fair lending, disclosures of credit terms and estimated transaction costs to consumer borrowers, debt collection practices, the use of and the provision of information to consumer reporting agencies, and the prohibition of unfair, deceptive, or abusive acts or practices in connection with the offer, sale, or provision of consumer financial products and services.

Penalties for violations of the above laws may include fines, reimbursements, injunctive relief and other penalties.

Privacy, Data Protection and Cybersecurity

We are subject to a number of U.S. federal, state, local and foreign laws and regulations relating to consumer privacy and data protection. Under privacy protection provisions of the Gramm-Leach-Bliley Act of 1999 ("GLBA") and its implementing regulations and guidance, we are limited in our ability to disclose certain non-public information about consumers to non-affiliated third parties. Financial institutions, such as the Bank, are required by statute and regulation to notify consumers of their privacy policies and practices and, in some circumstances, allow consumers to prevent disclosure of certain personal information to a non-affiliated third party. In addition, such financial institutions must appropriately safeguard their customers’ nonpublic, personal information.

Data privacy and data protection are areas of increasing state legislative focus. For example, in June 2018, the Governor of California signed into law the California Consumer Privacy Act ("CCPA"). The CCPA, which became effective on January 1, 2020, applies to for-profit businesses that conduct business in California and meet certain revenue or data collection thresholds. The CCPA gives consumers the right to request disclosure of information collected about them, and whether that information has been sold or shared with others, the right to request deletion of personal information (subject to certain exceptions), the right to opt out of the sale of the consumer’s personal information, and the right not to be discriminated against for exercising these rights. The CCPA contains several exemptions, including that many, but not all, requirements of the CCPA are inapplicable to information that is collected, processed, sold, or disclosed pursuant to the GLBA. California voters also recently passed the CPRA, which took effect on January 1, 2023, and significantly modifies the CCPA, including imposing additional obligations on covered companies and expanding California consumers’ rights with respect to certain sensitive personal information. On July 8, 2022, the CPPA commenced formal rulemaking to adopt regulations to implement the CPRA. However, regulations did not come into effect prior to the CPRA’s effective date. The CPPA has stated that the earliest proposed regulations could be in effect is April 2023, potentially resulting in further uncertainty and requiring us to incur additional costs and expenses in an effort to comply with the regulations. In California, the CCPA, the CPRA, and upcoming regulations may be interpreted or applied in a manner inconsistent with our understanding.

In addition, numerous other states have also enacted or are in the process of enacting state-level privacy, data protection and/or data security laws and regulations. The federal government and regulators outside of the United States may also pass additional data privacy or data protection legislation, including possible amendment of the GLBA. For example, on November 23, 2021, the federal financial regulatory agencies published a final rule that will impose upon banking organizations and their service providers new notification requirements for significant cybersecurity incidents. Specifically, the final rule requires banking organizations to notify their primary federal regulator as soon as possible and no later than 36 hours after the discovery of a "computer-security incident" that rises to the level of a "notification incident" within the meaning attributed to those terms by the final rule. Banks' service providers are required under the final rule to notify any affected bank to or on behalf of which the service provider provides services "as soon as possible" after determining that it has experienced an incident that materially disrupts or degrades, or is reasonably likely to materially disrupt or degrade, covered services provided to such bank

6 TriCo Bancshares 2022 10-K

for as much as four hours. The final rule took effect on April 1, 2022 and banks and their service providers were required to be in compliance with the requirements of the rule by May 1, 2022.

Federal banking agencies, including the FDIC and FRB, have adopted guidelines for establishing information security standards and cybersecurity programs for implementing safeguards under the supervision of the board of directors. These guidelines, along with related regulatory materials, increasingly focus on risk management and processes related to information technology and the use of third parties in the provision of financial services.

Recent cyberattacks against banks and other financial institutions that resulted in unauthorized access to confidential customer information have prompted the federal banking regulators to issue extensive guidance on cybersecurity. Among other things, financial institutions are expected to design multiple layers of security controls to establish lines of defense and ensure that their risk management processes address the risks posed by compromised customer credentials, including security measures to authenticate customers accessing internet-based services. A financial institution also should have a robust business continuity program to recover from a cyberattack and procedures for monitoring the security of third-party service providers that may have access to nonpublic data at the institution. Further, the Company’s financial institution customers have obligations to safeguard their systems and sensitive information and the Company may be bound contractually and/or by regulation to comply with the same requirements. If the Company or its service providers fail to comply with applicable regulations and contractual requirements, the Company could be exposed to lawsuits, governmental proceedings or the imposition of fines, among other consequences.

In February 2018, the SEC published interpretive guidance to assist public companies in preparing disclosures about cybersecurity risks and incidents. These SEC guidelines, and any other regulatory guidance, are in addition to notification and disclosure requirements under state and federal banking law and regulations. We and other U.S. financial services providers continue to be targeted with evolving and adaptive cybersecurity threats from sophisticated third parties. Unauthorized access or cybersecurity incidents could occur more frequently and on a more significant scale. If future attacks are successful or if customers are unable to access their accounts online for other reasons, it could adversely impact our ability to service customer accounts or loans, complete financial transactions for our customers or otherwise operate any of our businesses or services. In addition, a breach or attack affecting one of our third-party service providers or partners could harm our business even if we do not control the service that is attacked.

Any inability to prevent or adequately respond to the issues described above could disrupt the Company’s business, inhibit its ability to retain existing customers or attract new customers, otherwise harm its reputation and/or result in financial losses, litigation, increased costs or other adverse consequences that could be material to the Company. See Risk Factors below for additional information and discussion related to cybersecurity.

Like other lenders, the Bank uses credit bureau data in their underwriting activities. Use of such data is regulated under the Fair Credit Reporting Act (“FCRA”), and the FCRA also regulates reporting information to credit bureaus, prescreening individuals for credit offers, sharing of information between affiliates, and using affiliate data for marketing purposes. Similar state laws may impose additional requirements on the Company and the Bank.

Regulatory Capital Requirements

The Company and the Bank are subject to the minimum capital requirements of the FRB and FDIC, respectively. Capital requirements may have an effect on the Company’s and the Bank’s profitability and ability to pay dividends. If the Company or the Bank lacks adequate capital to increase its assets without violating the minimum capital requirements or if it is forced to reduce the level of its assets in order to satisfy regulatory capital requirements, its ability to generate earnings would be reduced.

We are subject to the capital framework for U.S. banking organizations known as Basel III. Basel III defines several measures of capital and establishes capital ratios based on a banking organizations levels of capital relative to risk-weighted assets. The risk-weighting of the asset depends on the nature of the asset but generally ranges from 0% for U.S. government and agency securities, to 1,250% for certain trading securitization exposures, resulting in higher risk weights for a variety of asset classes than previous regulations.

Under Basel III, we are subject to the following minimum capital ratios: (1) common equity Tier 1 capital or “CET1” to risk‑weighted assets of 4.5%; (2) Tier 1 capital (that is, CET1 plus Additional Tier 1 capital) to risk‑weighted assets of 6.0%; (3) Total capital (that is, Tier 1 capital plus Tier 2 capital) to risk‑weighted assets of 8%; and (4) a leverage ratio (Tier 1 capital to average consolidated assets as reported on regulatory financial statements) of 4.0%. The Basel III capital framework includes a “capital conservation buffer” of 2.5%, composed entirely of CET1, on top of the minimum risk‑weighted asset ratios. Banking institutions that fail to maintain a full capital conservation buffer face constraints on dividends, equity repurchases and discretionary executive compensation based on the amount of the shortfall and the institution’s “eligible retained income” (that is, four quarter trailing net income, net of distributions and tax effects not reflected in net income). The 2.5% capital conservation buffer effectively results in minimum ratios of (i) CET1 to risk‑weighted assets of at least 7%, (ii) Tier 1 capital to risk‑weighted assets of at least 8.5%, and (iii) total capital to risk‑weighted assets of at least 10.5%.

We believe that we were in compliance with the requirements of the Basel III capital rules applicable to us as of December 31, 2022. For a discussion of the regulatory capital requirements, see “Note 26 – Regulatory Matters” to the consolidated financial statements at Part II, Item 8 of this report.

Prompt Corrective Action

Prompt Corrective Action regulations of the federal bank regulatory agencies establish five capital categories in descending order based on an institution’s regulatory capital ratios: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized and critically

7 TriCo Bancshares 2022 10-K

undercapitalized. Under the Prompt Corrective Action framework, insured depository institutions are required to meet the following minimum capital level requirements in order to qualify as “well capitalized:” (i) a common equity Tier 1 capital ratio of 6.5%; (ii) a Tier 1 capital ratio of 8%; (iii) a total capital ratio of 10%; and (iv) a Tier 1 leverage ratio of 5%. An institution may be downgraded to, or deemed to be in, a capital category that is lower than indicated by its capital ratios if it is determined to be in an unsafe or unsound condition or if it receives an unsatisfactory examination rating with respect to certain matters. Institutions classified in one of the three undercapitalized categories are subject to certain mandatory and discretionary supervisory actions, which include increased monitoring and review, implementation of capital restoration plans, asset growth restrictions, limitations upon expansion and new business activities, requirements to augment capital, restrictions upon deposit gathering and interest rates, replacement of senior executive officers and directors, and requiring divestiture or sale of the institution. The Bank’s capital levels have exceeded the minimums necessary to be considered well capitalized under the current regulatory framework for prompt corrective action since adoption.

Deposit Insurance

Deposit accounts in the Bank are insured by the FDIC, generally up to a maximum of $250,000 per separately insured depositor. The Bank pays deposit insurance assessments as determined by the FDIC. The assessment rate for an institution with less than $10.0 billion in assets, such as the Bank, is based on its risk category, with certain adjustments for any unsecured debt or brokered deposits held by the bank. The assessment base against which the assessment rate is applied to determine the total assessment due for a given period is the depository institution’s average total consolidated assets during the assessment period less average tangible equity during that assessment period. Institutions assigned to higher risk categories (that is, institutions that pose a higher risk of loss to the FDIC’s deposit insurance fund (the “DIF”)) pay assessments at higher rates than institutions that pose a lower risk. An institution’s risk classification is assigned based on a combination of its financial ratios and supervisory ratings, reflecting, among other things, its capital levels and the level of supervisory concern that the institution poses to the regulators. In addition, the FDIC can impose special assessments in certain instances.

The FDIC, as required under the FDIA, established a plan on September 15, 2020, to restore the DIF reserve ratio to meet or exceed the statutory minimum of 1.35% within eight years. This plan did not include an increase in the deposit insurance assessment rate. Based on the FDIC’s recent projections, however, the FDIC determined that the DIF reserve ratio is at risk of not reaching the statutory minimum by the statutory deadline of September 30, 2028 without increasing the deposit insurance assessment rates. In October 2022, the FDIC adopted a final rule to increase initial base deposit insurance assessment rate schedules uniformly by 2 basis points, beginning on January 1, 2023. The FDIC also concurrently maintained the Designated Reserve Ratio for the DIF at 2%.

The Bank is generally unable to control the amount of premiums that it is required to pay for FDIC insurance or the amount of credit, if any, that it may be allowed to offset such assessments. If there are additional bank or financial institution failures or if the FDIC otherwise determines, the Bank may be required to pay even higher FDIC premiums than the recently increased levels. Increases in FDIC insurance premiums may have a material and adverse effect on the Company’s earnings and could have a material adverse effect on the value of, or market for, the Company’s common stock.

The FDIC may terminate a depository institution’s deposit insurance upon a finding that the institution’s financial condition is unsafe or unsound or that the institution has engaged in unsafe or unsound practices that pose a risk to the DIF or that may prejudice the interest of the bank’s depositors. The termination of deposit insurance for the Bank would also result in the revocation of the Bank’s charter by the DPFI.

Bank Secrecy Act / Anti-Money Laundering

The Bank Secrecy Act of 1970 (“BSA”) requires financial institutions to develop policies, procedures, and practices to prevent and deter money laundering, mandates that every bank have a written, board-approved program that is reasonably designed to assure and monitor compliance with the BSA. The program must, at a minimum: (1) provide for a system of internal controls to assure ongoing compliance; (2) provide for independent testing for compliance; (3) designate an individual responsible for coordinating and monitoring day-to-day compliance; and (4) provide training for appropriate personnel. In addition, banks are required to adopt a customer identification program as part of their BSA compliance program. Banks are also required to file reports when they detect certain known or suspected violations of federal law or suspicious transactions related to a money laundering activity or a violation of the BSA. BSA regulations require that we that we verify customer information when opening a new account, which includes identifying and verifying the beneficial owners of all customer that are legal entity customers, and performing ongoing customer due diligence to understand the nature and purpose of customer relationships for the purpose of developing customer risk profiles.

In addition to complying with the BSA, the Bank is subject to the USA Patriot Act of 2001 (“Patriot Act”). The Patriot Act is designed to deny terrorists and criminals the ability to obtain access to the United States’ financial system and has significant implications for depository institutions, brokers, dealers, and other businesses involved in the transfer of money. The Patriot Act mandates that financial service companies implement additional policies and procedures and take heightened measures designed to address any or all of the following matters: customer identification programs, money laundering, terrorist financing, identifying and reporting suspicious activities and currency transactions, currency crimes, and cooperation between financial institutions and law enforcement authorities.

On December 3, 2019, three federal banking agencies and the Financial Crimes Enforcement Network (“FinCEN”) issued a joint statement clarifying the compliance procedures and reporting requirements that banks must file for customers engaged in the growth or cultivation of hemp, including a clear statement that banks need not file a SAR on customers engaged in the growth or cultivation of hemp in accordance with applicable laws and regulations. This statement does not apply to cannabis-related business; thus, the statement only pertains to customers who are lawfully growing or cultivating hemp and are not otherwise engaged in unlawful or suspicious activity.

8 TriCo Bancshares 2022 10-K

Further, on January 1, 2021, Congress passed the National Defense Authorization Act, which enacted the most significant overhaul of the BSA and related AML laws since the Patriot Act. Notable amendments include (1) significant changes to the collection of beneficial ownership information and the establishment of a beneficial ownership registry, which requires corporate entities (generally, any corporation, LLC, or other similar entity with 20 or fewer employees and annual gross income of $5 million or less) to report beneficial ownership information to FinCEN (which will be maintained by FinCEN and made available upon request to financial institutions); (2) enhanced whistleblower provisions, which provide that one or more whistleblowers who voluntarily provide original information leading to the successful enforcement of violations of the AML laws in any judicial or administrative action brought by the Secretary of the Treasury or the Attorney General resulting in monetary sanctions exceeding $1 million (including disgorgement and interest but excluding forfeiture, restitution, or compensation to victims) will receive not more than 30 percent of the monetary sanctions collected and will receive increased protections; (3) increased penalties for violations of the BSA; (4) improvements to existing information sharing provisions that permit financial institutions to share information relating to SARs with foreign branches, subsidiaries, and affiliates (except those located in China, Russia, or certain other jurisdictions) for the purpose of combating illicit finance risks; and (5) expanded duties and powers of FinCEN. Many of the amendments require the Department of Treasury and FinCEN to promulgate rules. On September 29, 2022, FinCEN issued final regulations implementing the amendments with respect to beneficial ownership.

Office of Foreign Assets Control Regulation

The U.S. Treasury Department’s Office of Foreign Assets Control, or OFAC, administers and enforces economic and trade sanctions against targeted foreign countries and regimes, under authority of various laws, including designated foreign countries, nationals and others. OFAC publishes lists of specially designated targets and countries. We are responsible for, among other things, blocking accounts of, and transactions with, such targets and countries, prohibiting unlicensed trade and financial transactions with them and reporting blocked transactions after their occurrence. Failure to comply with these sanctions could have serious financial, legal and reputational consequences, including causing applicable bank regulatory authorities not to approve merger or acquisition transactions when regulatory approval is required or to prohibit such transactions even if approval is not required.

Transactions with Affiliates

Banks are also subject to certain restrictions imposed by the Federal Reserve Act on extensions of credit to executive officers, directors, principal shareholders (including the Company) or any related interest of such persons. Extensions of credit must be made on substantially the same terms, including interest rates and collateral as, and follow credit underwriting procedures that are not less stringent than, those prevailing at the time for comparable transactions with persons not affiliated with the bank, and must not involve more than the normal risk of repayment or present other unfavorable features. Banks are also subject to certain lending limits and restrictions on overdrafts to such persons. Regulation W requires that certain transactions between the Bank and its affiliates, including its holding company, be on terms substantially the same, or at least as favorable to the Bank, as those prevailing at the time for comparable transactions with or involving non-affiliated companies or, in the absence of comparable transactions, on terms and under circumstances, including credit standards, that in good faith would be offered to or would apply to non-affiliated companies.

Interchange Fees

Under the Durbin Amendment, adopted as part of the Dodd-Frank Act, the FRB adopted rules establishing standards for assessing whether the interchange fees that may be charged with respect to certain electronic debit transactions are “reasonable and proportional” to the costs incurred by issuers for processing such transactions.

Interchange fees, or “swipe” fees, are charges that merchants pay to us and other card-issuing banks for processing electronic payment transactions. FRB rules applicable to financial institutions that have assets of $10 billion or more provide that the maximum permissible interchange fee for an electronic debit transaction is the sum of 21 cents per transaction and 5 basis points multiplied by the value of the transaction. An upward adjustment of no more than 1 cent to an issuer's debit card interchange fee is allowed if the card issuer develops and implements policies and procedures reasonably designed to achieve certain fraud-prevention standards. The FRB also has rules governing routing and exclusivity that require issuers to offer two unaffiliated networks for routing transactions on each debit or prepaid product. Effective July 1, 2023, a new FRB Federal Reserve rule will require that debit card issuers enable all debit card transactions, including card-not-present transactions such as online payments, to be processed on at least two unaffiliated payment card networks. The Bank is currently not subject to these restrictions, however if our assets exceed $10 billion or more at December 31, 2023, these rules would be applicable to the Bank in July 2024.

Impact of Monetary Policies

Banking is a business that depends on interest rate differentials. In general, the difference between the interest paid by a bank on its deposits and other borrowings, and the interest rate earned by banks on loans, securities and other interest-earning assets, comprises the major source of banks’ earnings. Thus, the earnings and growth of banks are subject to the influence of economic conditions generally, both domestic and foreign, and also to the monetary and fiscal policies of the United States and its agencies, particularly the FRB. The FRB implements national monetary policy, such as seeking to curb inflation and combat recession, by its open-market dealings in United States government securities, by adjusting the required level of reserves for financial institutions subject to reserve requirements and through adjustments to the discount rate applicable to borrowings by banks which are members of the FRB. The actions of the FRB in these areas influence the growth of bank loans, investments and deposits, and also affect interest rates. The nature and timing of any future changes in such policies and their impact on the Company cannot be predicted. In addition, adverse economic conditions could make a higher provision for loan losses a prudent course and could cause higher loan loss charge-offs, thus adversely affecting the Company’s net earnings.

Incentive Compensation Policies and Restrictions

9 TriCo Bancshares 2022 10-K

In July 2010, the federal banking agencies issued guidance on sound incentive compensation policies that applies to all banking organizations supervised by the agencies (thereby including both the Company and the Bank). Pursuant to the guidance, to be consistent with safety and soundness principles, a banking organization’s incentive compensation arrangements should: (1) provide employees with incentives that appropriately balance risk and reward; (2) be compatible with effective controls and risk management; and (3) be supported by strong corporate governance including active and effective oversight by the banking organization’s board of directors. Monitoring methods and processes used by a banking organization should be commensurate with the size and complexity of the organization and its use of incentive compensation.

The Dodd-Frank Act requires the federal banking agencies and the SEC to establish joint regulations or guidelines for specified regulated entities, such as us, having at least $1 billion in total assets, to prohibit incentive-based payment arrangements that encourage inappropriate risk taking by providing an executive officer, employee, director or principal shareholder with excessive compensation, fees, or benefits or that could lead to material financial loss to the entity. In addition, these regulators must establish regulations or guidelines requiring enhanced disclosure to regulators of incentive-based compensation arrangements. The agencies have not yet finalized these rules; however, on October 26, 2022, the SEC adopted a final rule regarding "clawbacks" of incentive-based executive compensation.

The scope and content of the U.S. banking regulators’ policies on executive compensation may continue to evolve in the near future. It cannot be determined at this time whether compliance with such policies will adversely affect the Company’s ability to hire, retain and motivate its key employees.

ITEM 1A.    RISK FACTORS

An investment in our securities is subject to certain risks. In addition to the other information in this report, investors should carefully consider the following discussion of significant risk and uncertainties before making investment decisions about our securities. The events and consequences discussed in these risk factors could, in circumstances we may or may not be able to accurately predict, recognize, or control, have a material adverse effect on our business, growth, reputation, prospects, financial condition, operating results (including components of our financial results) liquidity, and stock price. Any of these risk factors could cause our actual results to differ materially from our historical results or the results contemplated by the forward-looking statements contained in this report. These risk factors do not identify all risks that we face; our operations could also be affected by factors, events, or uncertainties that are not presently known to us or that we currently do not consider to present significant risks to our operations.

Risks Related to the Nature and Geographic Area of Our Business

The majority of our assets are loans, which are subject to credits risks.

As a lender, we face a significant risk that we will sustain losses because borrowers, guarantors or related parties may fail to perform in accordance with the terms of the loans we make or acquire. Our earnings are significantly affected by our ability to properly originate, underwrite and service loans. We have underwriting and credit monitoring procedures and credit policies, including the establishment and review of the allowance for credit losses, that we believe appropriately address this risk by assessing the likelihood of nonperformance, tracking loan performance and diversifying our respective loan portfolios. Such policies and procedures, however, may not prevent unexpected losses that could adversely affect our results of operations. We could sustain losses if we incorrectly assess the creditworthiness of our borrowers or fail to detect or respond to deterioration in asset quality in a timely manner or as a result of deteriorating economic conditions, for example.

Our allowance for credit losses may not be adequate to cover actual losses.

Like other financial institutions, we maintain an allowance for credit losses to provide for loan defaults and non-performance. Our allowance for credit losses may not be adequate to cover actual loan losses, and future provisions for loan losses would reduce our earnings and could materially and adversely affect our business, financial condition and results of operations. Our allowance for credit losses is based on prior experience, as well as an evaluation of the known risks in the current portfolio, composition and growth of the loan portfolio and actual and forecast economic factors. Determining an appropriate level of allowance is an inherently difficult process and is based on numerous assumptions. The actual amount of future losses is susceptible to changes in economic, operating and other conditions, including changes in interest rates, unemployment and gross domestic product that may be beyond our control and these losses may exceed current estimates. Effective January 1, 2020, we implemented a new accounting standard, “Measurement of Credit Losses on Financial Instruments,” commonly referred to as the “Current Expected Credit Losses” standard, or “CECL,” CECL changed the allowance for credit losses methodology from an incurred loss concept to an expected loss concept, which is more dependent on future economic forecasts, assumptions and models than previous methodology, which could result in increases and add volatility to our allowance for credit losses and future provisions for loan losses. These forecasts, assumptions and models are inherently uncertain and are based upon our management’s reasonable judgment in light of information currently available.

In addition to periodic reviews completed by independent third parties retained by the Bank, Federal and state bank regulatory agencies, as an integral part of their examination process, review our loans and allowance for credit losses. While we believe that our allowance for credit losses is adequate to cover estimated future losses, we cannot assure you that we will not increase the allowance for credit losses further or that the allowance will be adequate to absorb credit losses we actually incur. Credit losses in excess of our allowance or addition provisions to our allowance would reduce our net income and capital, potentially materially.

Our business may be adversely affected by business conditions in California.

We conduct most of our business in California. As a result of this geographic concentration, our financial results may be impacted by economic conditions in California. Deterioration in the economic conditions in California could result in the following consequences, any of which could have a material adverse effect on our business, financial condition, results of operations and cash flows:

•problem assets and foreclosures may increase,

•demand for our products and services may decline,

•low cost or non-interest bearing deposits may decrease, and

•collateral for loans made by us, especially real estate, may decline in value, in turn reducing customers’ borrowing power, and reducing the value of assets and collateral associated with our existing loans.

In view of the concentration of our operations and the collateral securing our loan portfolio in California, we may be particularly susceptible to the adverse effects of any of these consequences, any of which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Severe weather, natural disasters and other external events could adversely affect our business.

Our operations and our customer base are primarily located in California where natural and other disasters may occur. California is vulnerable to natural disasters and other risks, such as earthquakes, fires, droughts and floods, the nature and severity of which may be impacted by climate change. These types of natural catastrophic events have at times disrupted the local economies, our business and customers in these regions. Such events could also affect the stability of our deposit base; impair the ability of borrowers to obtain adequate insurance or repay outstanding loans, impair the value of collateral securing loans and cause significant property damage, result in losses of revenue and/or cause us to incur additional expenses. In addition, catastrophic events occurring in other regions of the world may have an impact on our customers and in turn, on us. Our business continuity and disaster recovery plans may not be successful upon the occurrence of one of these scenarios, and a significant catastrophic event anywhere in the world could materially adversely affect our operating results.

A significant majority of the loans in our portfolio are secured by California real estate and a decline in real estate values could hurt our business.

A downturn in real estate values in the markets which we conduct our business in California could hurt our business because most of our loans are secured by real estate. Real estate values and real estate markets are generally affected by changes in national, regional or local economic conditions, fluctuations in interest rates and the availability of loans to potential purchasers, changes in tax laws and other governmental statutes, regulations and policies. Real estate values could also be affected by, among other things, earthquakes, drought and national disasters. As real estate prices decline, the value of real estate collateral securing our loans is reduced. As a result, our ability to recover on defaulted loans by foreclosing and selling the real estate collateral could then be diminished and we would be more likely to suffer losses on defaulted loans. As of December 31, 2022, approximately 90.5% of the book value of our loan portfolio consisted of loans collateralized by various types of real estate. Substantially all of our real estate collateral is located in California. So, if there is a significant adverse decline in real estate values in California, the collateral for our loans will provide less security. Any such decline could have a material adverse effect on our business, financial condition and results of operations.

We are exposed to the risk of environmental liabilities with respect to properties to which we take title.

In the course of our business, we may foreclose and take title to real estate and could be subject to environmental liabilities with respect to these properties. We may be held liable to a governmental entity or to third parties for property damage, personal injury, investigation and clean-up costs incurred by these parties in connection with environmental contamination, or may be required to investigate or clean-up hazardous or toxic substances, or chemical releases at a property. The costs associated with investigation or remediation activities could be substantial. In addition, if we are the owner or former owner of a contaminated site, we may be subject to common law claims by third parties based on damages and costs resulting from environmental contamination emanating from the property. When applicable, we establish contingent liability reserves for this purpose based on future reasonable and estimable costs developed by qualified soil and chemical engineering consultants. If we become subject to significant environmental liabilities or if our contingency reserve estimates are incorrect, our business, financial condition and results of operations could be materially adversely affected.

We face strong competition from financial services companies and other companies that offer similar services, which could materially and adversely affect our business.

Competition in the banking and financial services industry is intense. Our profitability depends upon our continued ability to successfully compete. We primarily compete in California for loans, deposits and customers with commercial banks, savings and loan associations, credit unions, finance companies, mutual funds, insurance companies, brokerage firms and Internet-based marketplace lending platforms. Our competitors include major financial companies whose greater resources may afford them a marketplace advantage by enabling them to maintain numerous locations and mount extensive promotional and advertising campaigns. Additionally, banks and other financial institutions with larger capitalization and financial intermediaries that are not subject to bank regulatory restrictions may have larger lending limits which would allow them to serve the credit needs of larger customers. Areas of competition include interest rates for loans and deposits, efforts to obtain loan and deposit customers and a range in quality of products and services provided, including new technology-driven products and services. Technological innovation continues to contribute to greater competition in domestic and international financial

11 TriCo Bancshares 2022 10-K

services markets as technological advances enable more companies, such as Internet-based marketplace lenders, financial technology (or “fintech”) companies that rely on technology to provide financial services, often without many of the regulatory and capital restrictions that we face. We also face competition from out-of-state financial intermediaries that have opened loan production offices or that solicit deposits in our market areas. If we are unable to attract and retain banking customers, we may be unable to continue our loan growth and level of deposits and our business, financial condition and results of operations be adversely affected.

We may be adversely affected by the soundness of other financial institutions.

Financial services institutions are interrelated as a result of clearing, counterparty, or other relationships. We have exposure to many different industries and counterparties, and routinely execute transactions with counterparties in the financial services industry, including commercial banks, brokers and dealers, and other institutional clients. Many of these transactions expose us to credit risk in the event of a default by a counterparty or client. In addition, our credit risk may be exacerbated when the collateral that we hold cannot be realized upon or is liquidated at prices not sufficient to recover the full amount of the credit or derivative exposure due to us. Any such losses could have a material adverse effect on our financial condition and results of operations.

We may need to raise additional capital, but it may not be available on acceptable terms or at all.

We are required by federal and state regulators to maintain adequate levels of capital. We may need to raise additional capital in the future to meet regulatory or other internal requirements. Our ability to raise additional capital, if needed, will depend on, among other things, conditions in the capital markets at that time, which are outside of our control, and our financial performance.

We cannot provide any assurance that access to such capital will be available to us on acceptable terms or at all. An event that may limit our access to the capital markets, such as a decline in the confidence of investors or counter-parties participating in the capital markets, may materially and adversely affect our capital costs and our ability to raise capital and, in turn, our liquidity. Further, if we need to raise capital in the future, we may have to do so when many other financial institutions are also seeking to raise capital and we would then have to compete with those institutions for investors. The inability to raise additional capital on acceptable terms when needed could have a materially adverse effect on our business, financial condition, or results of operations.

Adverse changes in economic or market conditions may hurt our businesses.

Our success depends, to a certain extent, upon local, national and global economic and political conditions, as well as governmental monetary policies. Conditions such as an economic recession, rising unemployment, inflation, changes in interest rates, declines in asset values and other factors beyond our control may adversely affect our asset quality, deposit levels and our net income. Adverse changes in the economy may also have a negative effect on the demand for new loans and the ability of our existing borrowers to make timely repayments of their loans, which could adversely impact our growth and earnings. Economic and market conditions may also be affected by political developments in the U.S. and other countries and global conflicts, such as the conflict in Ukraine. Uncertainty about the federal fiscal policymaking process, the fiscal outlook of the federal government, and future tax rates is a concern for businesses, consumers and investors in the United States The COVID-19 pandemic has caused and may continue to cause disruptions in the U.S. economy at large, and for small businesses in particular, and has resulted and may continue to result in disruptions to our customers’ businesses, and a decrease in consumer confidence and business generally.

If the United States economy weakens or does not improve, our growth and profitability from our lending, deposit and investment operations could be constrained. Any of these potential outcomes could cause us to suffer losses in our investment securities portfolio, reduce our liquidity and capital levels, hamper our ability to deliver products and services to our clients and customers, and weaken our results of operations and financial condition.

The effects of COVID-19 or a similar health crisis or pandemic, could adversely affect or operations or financial performance.

While U.S. and global economies have begun to recover from the COVID-19 pandemic and many health and safety restrictions have been lifted, certain adverse consequences of the pandemic, including labor shortages, disruptions of global supply chains, and inflationary pressures, continue to impact the economy and could adversely affect our business.

The ongoing nature of the pandemic and its effects, such as changes in customer behaviors and preferences, are difficult to predict. The pandemic or a similar health crisis could cause us to recognize credit losses in our loan portfolios and increases in our allowance for credit losses, particularly if the effects of the pandemic worsen or continue for an extended period of time. Our business depends on the willingness and ability of our customers and employees to conduct banking and other financial transactions. Disruptions to our customers caused by the COVID-19 pandemic could result in increased risk of delinquencies, defaults, foreclosures and losses on our loans, as well as reductions in loan demand, the liquidity of loan guarantors, loan collateral values (particularly in real estate), loan originations, interest and noninterest income and deposit availability. Furthermore, the pandemic could cause us to recognize impairment of our goodwill and our financial assets.

The COVID-19 pandemic has also resulted in heightened operational risks. Some of our colleagues continue to work remotely at least part-time basis, which may create additional cybersecurity risks. The increase in online and remote banking activities may also increase the risk of fraud in certain instances.

Risks Related to Interest Rates

12 TriCo Bancshares 2022 10-K

Changes in interest rates may make it difficult for us to improve or maintain our current interest income spread and could result in reduced earnings and negatively impact our financial performance.

Like other financial institutions, we are subject to risks resulting from changes in interest rates. Our primary source of income is net interest income, which is the difference between interest earned on loans and leases and investments, and interest paid on deposits and borrowings. Because of the differences in the maturities and repricing characteristics of our interest-earning assets and interest-bearing liabilities, changes in interest rates may not produce matching changes in interest income we earn on interest-earning assets and interest we pay on interest-bearing liabilities. Accordingly, fluctuations in interest rates could adversely affect our interest rate spread and, in turn, our profitability.

In addition, loan and lease volume and quality and deposit volume and mix can be affected by market interest rates as can the businesses of our clients. Changes in levels of market interest rates could have a material adverse effect on our net interest spread, asset quality, origination volume, the value of our loans and investment securities, deposit levels and overall profitability.

Interest rates may be affected by many factors that are beyond the control of our management, including general economic conditions and the policies of various governmental and regulatory authorities. The actions of the Federal Reserve Board influence the rates of interest that we charge on loans and that we pay on borrowings and interest-bearing deposits. Changes in monetary policy, including changes in interest rates, may negatively affect our ability to originate loans and leases, the value of our assets and our ability to realize gains from the sale of our assets, all of which ultimately could affect our earnings. In addition, the Federal Reserve raised benchmark interest rates throughout 2022 and may continue to raise interest rates in response to economic conditions, particularly inflationary pressures. We cannot predict the nature or timing of future changes in monetary, tax and other policies or the effects that they may have on our activities and financial results.

Our business is subject to interest rate risk and variations in interest rates may negatively affect our financial performance.

Although we were successful in generating new loans during 2022, increasing interest rates may adversely affect the demand for new loans and our loan growth. To supplement our organic loan growth, we from time-to-time will purchase loans from third parties that may have lower yields than those loans that we originate on our own.

Additionally, interest rate increases often result in larger payment requirements for our borrowers with variable rate loans, which increases the potential for default and could result in a decrease in the demand for loans. At the same time, the marketability of the property securing a loan may be adversely affected by any reduced demand resulting from higher interest rates. An increase in interest rates that adversely affects the ability of borrowers to pay the principal or interest on loans may lead to an increase in nonperforming assets and a reversal of income previously recognized, which could have an adverse effect on our results of operations. Further, when we place a loan on nonaccrual status, we reverse any accrued but unpaid interest receivable, which decreases interest income. At the same time, we continue to incur costs to fund the loan, which is reflected as interest expense, without any interest income to offset the associated funding expense. Thus, an increase in the amount of nonperforming assets would have an adverse impact on net interest income. Furthermore, if short-term market rates rise, in order to retain existing deposit customers and attract new deposit customers we may need to increase rates we pay on deposit accounts.

Accordingly, changes in levels of market interest rates could materially and adversely affect our net interest spread, asset quality, loan origination volume, business, financial condition and results of operations.

Higher inflation could have a negative impact on our financial results and operations.

Inflation may negatively affect us by increasing our labor costs, through higher wages and higher interest rates, which may negatively affect the market value of securities on our balance sheet, higher interest expenses on our deposits, especially CDs, and a higher cost of our borrowings. Additionally, higher inflation levels could lead to higher oil and gas prices, which may negatively impact the net operating income on the properties which we lend on and could impair a borrower's ability to repay their loans.

Elevated inflation and expectations for elevated future inflation can adversely impact economic growth, consumer and business confidence, and our financial condition and results. In addition, elevated inflation may cause unexpected changes in monetary policies and actions which may adversely affect confidence, the economy, and our financial condition and results.

Supply chain constraints and a tightening labor markets could potentially exacerbate inflation and sustain it at elevated levels, even as growth slows. The risk of sustained high inflation would likely be accompanied by monetary policy tightening with potential negative effects on various elevated asset classes.

Reduction in the value, or impairment of our investment securities, can impact our earnings and common shareholders’ equity.

We maintained a balance of $2.6 billion, or approximately 26% of our assets, in investment securities at December 31, 2022. Changes in market interest rates can affect the fair value of these investment securities, with increasing interest rates generally resulting in a reduction of value. Although the reduction in value from temporary increases in market rates does not affect our income until the security is sold, it does result in an unrealized loss recorded in other comprehensive income that can reduce our common stockholders’ equity. Further, we must periodically test our investment securities for other-than-temporary impairment in value. In assessing whether the impairment of investment securities is other-than-temporary, we consider the length of time and extent to which the fair value has been less than cost, the financial condition and near-term prospects of the issuer, and the intent and ability to retain our investment in the security for a period of time sufficient to allow for any anticipated recovery in fair value in the near term.

Changes to LIBOR or SOFR may adversely affect the value of, and the return on, our financial instruments that are indexed to LIBOR or SOFR.

In July 2017, the U.K. Financial Conduct Authority, which regulates LIBOR, announced that it will no longer persuade or compel banks to submit rates for the calculation of LIBOR to the LIBOR administrator after 2021. The announcement indicates that the continuation of LIBOR on the current basis cannot and will not be guaranteed after 2021. In November 2020, the LIBOR administrator published a consultation regarding its intention to delay the date on which it will cease publication of U.S. dollar LIBOR from December 31, 2021 to June 30, 2023 for the most common tenors of U.S. dollar LIBOR, including the three-month LIBOR, but indicated no new contracts using U.S. dollar LIBOR should be entered into after December 31, 2021. Notwithstanding the publication of this consultation, there is no assurance of how long LIBOR of any currency or tenor will continue to be published. It is impossible to predict whether and to what extent banks will continue to provide LIBOR submissions to the administrator of LIBOR, whether LIBOR rates will cease to be published before June 30, 2023, or whether any additional reforms to LIBOR may be enacted in the United Kingdom or elsewhere. Although the Alternative Reference Rates Committee has announced Secured Overnight Financing Rate (“SOFR”) as its recommended alternative to LIBOR, SOFR may not gain market acceptance or be widely used as a benchmark. Uncertainty as to the nature of such potential changes, alternative reference rates, the elimination or replacement of LIBOR, or other reforms may adversely affect the value of, and the return on our financial instruments.

The market transition away from LIBOR to alternative reference rates is complex and could have a range of adverse effects on the Company’s business, financial condition, and results of operations. In particular, any such transition could:

•adversely affect the interest rates received or paid on the revenue and expenses associated with or the value of the Company’s LIBOR-based assets and liabilities;

•adversely affect the interest rates received or paid on the revenue and expenses associated with or the value of other securities or financial arrangements, given LIBOR's role in determining market interest rates globally;

•prompt inquiries or other actions from regulators in respect of the Company’s preparation and readiness for the replacement of LIBOR with an alternative reference rate; and

•result in disputes, litigation, or other actions with borrowers or counterparties about the interpretation and enforceability of certain fallback language in LIBOR-based contracts and securities.

Risks Related to Regulatory and Legal Matters

We operate in a highly regulated environment and we may be adversely affected by new laws and regulations or changes in existing laws and regulations. Any additional regulations are expected to increase our cost of operations. Furthermore, regulations may prevent or impair our ability to pay dividends, engage in acquisitions or operate in other ways.

We are subject to extensive regulation, supervision and examination by the DPFI, FDIC, and the FRB. See Item 1—Regulation and Supervision of this report for information on the regulation and supervision which governs our activities. Regulatory authorities have extensive discretion in their supervisory and enforcement activities, including the imposition of restrictions on our operations, the classification of our assets and determination of the level of our allowance for credit losses. Banking regulations, designed primarily for the protection of depositors, may limit our growth and the return to our shareholders by restricting certain of our activities, such as:

•the payment of dividends to our shareholders,

•possible mergers with or acquisitions of or by other institutions,

•desired investments,

•loans and interest rates on loans,

•interest rates paid on deposits,

•service charges on deposit account transactions,

•the possible expansion or reduction of branch offices, and

•the ability to provide new products or services.

We also are subject to regulatory capital requirements. We could be subject to regulatory enforcement actions if any of our regulators determines for example, that we have violated a law of regulation, engaged in unsafe or unsound banking practice or lack adequate capital. Federal and state governments and regulators could pass legislation and adopt policies responsive to current credit conditions that would have an adverse effect on us and our financial performance. We cannot predict what changes, if any, will be made to existing federal and state legislation and regulations or the effect that such changes may have on our future business and earnings prospects. Any change in such regulation and oversight, whether in the form of regulatory policy, regulations, legislation or supervisory action, may have a material adverse impact on our operations, including the cost to conduct business.

Risks Related to Our Growth and Expansion

Goodwill resulting from acquisitions may adversely affect our results of operations.

Our goodwill and other intangible assets have increased substantially as a result of our acquisitions of Valley Republic Bank in 2022, FNB Bancorp in 2018 and North Valley Bancorp in 2014. Potential impairment of goodwill and amortization of other intangible assets could adversely affect our financial condition and results of operations. We assess our goodwill and other intangible assets and long-lived assets for impairment annually and more frequently when required by U.S. GAAP. We are required to record an impairment charge if circumstances indicate that the asset carrying values exceed their fair values. Our assessment of goodwill, other intangible assets, or long-lived assets could indicate that an impairment of the carrying value of such assets may have occurred that could result in a material, non-cash write-down of such assets, which could have a material adverse effect on our results of operations and future earnings.

Potential acquisitions create risks and may disrupt our business and dilute shareholder value.

We intend to continue to explore opportunities for growth through mergers and acquisitions. Acquiring other banks, businesses, or branches involves various risks commonly associated with acquisitions, including, among other things:

•incurring substantial expenses in pursuing potential acquisitions without completing such acquisitions,

•exposure to potential asset quality issues of the target company,

•losing key clients as a result of the change of ownership,

•the acquired business not performing in accordance with our expectations,

•difficulties and expenses arising in connection with the integration of the operations or systems conversion of the acquired business with our operations,

•difficulty in estimating the value of the target company,

•potential exposure to unknown or contingent liabilities of the target company,

•management needing to divert attention from other aspects of our business,

•potentially losing key employees of the acquired business,

•incurring unanticipated costs which could reduce our earnings per share,

•assuming potential liabilities of the acquired company as a result of the acquisition,

•potential changes in banking or tax laws or regulations that may affect the target company,

•potential disruption to our business, and

•an acquisition may dilute our earnings per share, in both the short and long term, or it may reduce our tangible capital ratios.

Acquisitions may be delayed, impeded, or prohibited due to regulatory issues.

Acquisitions by financial institutions, including us, are subject to approval by a variety of federal and state regulatory agencies. The process for obtaining these required regulatory approvals has become substantially more difficult since the global financial crisis and more recently due to political actions. Furthermore, our ability to engage in certain merger or acquisition transactions depends on the bank regulators' views at the time as to our capital levels, quality of management, and overall condition, in addition to their assessment of a variety of other factors, including our compliance with laws and regulations. Regulatory approvals could be delayed, impeded, restrictively conditioned or denied due to existing or new regulatory issues we have, or may have, with regulatory agencies, including, without limitation, issues related to BSA compliance, CRA compliance, fair lending laws, fair housing laws, consumer protection laws and other laws and regulations. We may fail to pursue, evaluate or complete strategic and competitively significant acquisition opportunities as a result of our inability, or perceived or anticipated inability, to obtain regulatory approvals in a timely manner, under reasonable conditions or at all. Difficulties associated with potential acquisitions that may result from these factors could have a material adverse effect on our business, financial condition and results of operations.

If we cannot attract deposits, our growth may be inhibited.

We plan to increase the level of our assets, including our loan portfolio. Our ability to increase our assets depends in large part on our ability to attract additional deposits at favorable rates. We intend to seek additional deposits by offering deposit products that are competitive with those offered by other financial institutions in our markets and by establishing personal relationships with our customers. We cannot assure that these efforts will be successful. Our inability to attract additional deposits at competitive rates could have a material adverse effect on our business, financial condition and results of operations.

Our growth and expansion may strain our ability to manage our operations and our financial resources.

15 TriCo Bancshares 2022 10-K

Our financial performance and profitability depend on our ability to execute our corporate growth strategy. In addition to seeking deposit and loan and lease growth in our existing markets, we may pursue expansion opportunities in new markets, enter into new lines of business or market areas or offer new products or services. Continued growth, however, may present operating and other problems that could adversely affect our business, financial condition and results of operations. Furthermore, any new line of business or market areas and/or new products or services could have a significant impact on the effectiveness of our system of internal controls. Accordingly, there can be no assurance that we will be able to execute our growth strategy or maintain the level of profitability that we have recently experienced.

Our growth may place a strain on our administrative, operational and financial resources and increase demands on our systems and controls. This business growth may require continued enhancements to and expansion of our operating and financial systems and controls and may strain or significantly challenge them. In addition, our existing operating and financial control systems and infrastructure may not be adequate to maintain and effectively monitor future growth. Our continued growth may also increase our need for qualified personnel. We cannot assure you that we will be successful in attracting, integrating and retaining such personnel.

We will become subject to increased regulation when we have more than $10 billion in total consolidated assets.

An insured depository institution with $10 billion or more in total assets is subject to supervision, examination, and enforcement with respect to consumer protection laws by the CFPB rather than its primary federal banking regulator. Under its current policies, the CFPB will assert jurisdiction in the first quarter after an insured depository institution’s call reports show total consolidated assets of $10 billion or more for four consecutive quarters. The Bank had slightly less than $10 billion in total assets at December 31, 2022, so it is possible that with only modest growth, the CFPB, instead of the FDIC, may soon have primary examination and enforcement authority over the Bank. As an independent bureau within the Federal Reserve Board focused solely on consumer financial protection, the CFPB may interpret or enforce consumer protection laws more strictly or severely than the FDIC.

Additionally, other regulatory requirements apply to depository institutions and holding companies with $10 billion or more in total consolidated assets, including a cap on interchange transaction fees for debit cards, as required by Federal Reserve Board regulations, which would reduce our interchange revenue, and restrictions on proprietary trading and investment and sponsorship in hedge funds and private equity funds known as the Volcker Rule. See also Item 1 - Regulation and Supervision - Interchange Fees in this report. Further, deposit insurance assessment rates are calculated differently, and may be higher, for insured depository institutions with $10 billion or more in total consolidated assets.

Risks Relating to Ownership of Our Common Stock

Our ability to pay dividends is subject to legal and regulatory restrictions.

Our ability to pay dividends to our shareholders is limited by California law and the policies and regulations of the FRB. The FRB has issued a policy statement on the payment of cash dividends by bank holding companies, which expresses the FRB’s view that a bank holding company should pay cash dividends only to the extent that its net income for the past year is sufficient to cover both the cash dividends and a rate of earnings retention that is consistent with the holding company’s capital needs, asset quality and overall financial condition. See “Regulation and Supervision – Restrictions on Dividends and Distributions.”

As a holding company with no significant assets other than the Bank, our ability to continue to pay dividends depends in large part upon the Bank’s ability to pay dividends to us. The Bank’s ability to pay dividends or make other capital distributions to us is subject to the restrictions in the California Financial Code.

Our ability to pay dividends to our shareholder and the ability of the Bank to pay in dividends to us are by the requirements that the we and the Bank maintain a certain minimum amount of capital to be considered a “well capitalized” institution as well as a separate capital conservation buffer, as further described under “Item 1 – Supervision and Regulation — Regulatory Capital Requirements” in this report.

From time to time, we may become a party to financing agreements or other contractual arrangements that have the effect of limiting or prohibiting us or the Bank from declaring or paying dividends. Our holding company expenses and obligations with respect to our trust preferred securities and corresponding junior subordinated deferrable interest debentures issued by us may limit or impair our ability to declare or pay dividends.

Provisions of our governing documents and federal law may limit the ability of another party to acquire us, which could cause our stock price to decline.

Various provisions of our articles of incorporation and bylaws could delay or prevent a third party from acquiring us, even if doing so might be beneficial to our shareholders. These provisions provide for, among other things, specified actions that the Board of Directors shall or may take when an offer to merge, an offer to acquire all assets or a tender offer is received and the authority to issue preferred stock by action of the board of directors acting alone, without obtaining shareholder approval.

The BHC Act and the Change in Bank Control Act of 1978, as amended, together with federal regulations, require that, depending on the particular circumstances, either FRB approval must be obtained or notice must be furnished to the Federal Reserve Board and not disapproved prior to any person or entity acquiring “control” of a bank holding company such as TriCo. These provisions may prevent a merger or acquisition that would be attractive to shareholders and could limit the price investors would be willing to pay in the future for our common stock

16 TriCo Bancshares 2022 10-K

Holders of our junior subordinated debentures have rights that are senior to those of our shareholders.

We have supported our growth through the prior issuance of trust preferred securities from special purpose trusts and accompanying junior subordinated debentures. At December 31, 2022, we had outstanding trust preferred securities and accompanying junior subordinated debentures with principal amount of $98,889,000. Payments of the principal and interest on the trust preferred securities are conditionally guaranteed by us. Further, the accompanying junior subordinated debentures we issued to the trusts are senior to our shares of common stock. As a result, we must make payments on the junior subordinated debentures before we can pay any dividends on our common stock and, in the event of our bankruptcy, dissolution or liquidation, the holders of the junior subordinated debentures must be satisfied before any distributions can be made on our common stock.

We may issue additional common stock or other equity securities in the future which could dilute the ownership interest of existing shareholders.

In order to maintain our capital at desired or regulatory-required levels, or to fund future growth, our board of directors may decide from time to time to issue additional shares of common stock, or securities convertible into, exchangeable for or representing rights to acquire shares of our common stock. The sale of these shares may significantly dilute your ownership interest as a shareholder. New investors in the future may also have rights, preferences and privileges senior to our current shareholders which may adversely impact our current shareholders.

The trading price of our common stock price can be volatile.

Stock price volatility may make it more difficult for our shareholders to resell their common stock when they want and at prices they find attractive. The trading price of our common stock can fluctuate significantly in response to a variety of factors including, among other things:

•     actual or anticipated variations in quarterly results of operations;

•     recommendations by securities analysts;

•     operating and stock price performance of other companies that investors deem comparable to the Company;

•    trends, concerns and other issues in the financial services industry or California economy;

•investor sentiments toward depository institutions generally;

•     marketplace perceptions in the marketplace regarding the Company and/or its competitors;

•     new technology used, or services offered, by competitors;

•     significant acquisitions or business combinations involving the Company or its competitors; and

•     changes in government regulations, including tax laws.

General market fluctuations, industry factors and general economic and political conditions and events, such as economic slowdowns or recessions, interest rate changes or credit loss trends could also cause the Company’s stock price to decrease regardless of operational results.

Risks Relating to Operations, Technology Systems, Accounting and Internal Controls

If we fail to maintain an effective system of internal and disclosure controls, we may not be able to accurately report our financial results or prevent fraud. As a result, current and potential shareholders could lose confidence in our financial reporting, which would harm our business and the trading price of our securities.

Effective internal control over financial reporting and disclosure controls and procedures are necessary for us to provide reliable financial reports and effectively prevent fraud and to operate successfully as a public company. If we cannot provide reliable financial reports or prevent fraud, our reputation and operating results would be harmed. We continually review and analyze our internal control over financial reporting for Sarbanes-Oxley Section 404 compliance. As part of that process we may discover material weaknesses or significant deficiencies in our internal control as defined under standards adopted by the Public Company Accounting Oversight Board that require remediation. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial statements will not be prevented or detected in a timely basis. A significant deficiency is a deficiency or combination of deficiencies, in internal control over financial reporting that is less severe than material weakness, yet important enough to merit attention by those responsible for the oversight of the Company’s financial reporting.

As a result of weaknesses that may be identified in our internal controls, we may also identify certain deficiencies in some of our disclosure controls and procedures that we believe require remediation. If we discover weaknesses, we will make efforts to improve our internal and disclosure controls. However, there is no assurance that we will be successful. Any failure to maintain effective controls or timely effect any necessary improvement of our internal and disclosure controls could harm operating results or cause us to fail to meet our reporting obligations, which could affect our ability to remain listed with Nasdaq. Ineffective internal and disclosure controls could also cause investors to lose confidence in our reported financial information, which would likely have a negative effect on the trading price of our securities.

A failure or breach, including cyberattacks, of our operational or security systems or of those of our customers or contracted vendors, could disrupt our business, result in the disclosure of confidential information, damage our reputation, and create significant financial and legal exposure.

We, our customers, our vendors, regulators and other third parties have been subject to, and are likely to continue to be the target of, cyberattacks. Although we devote significant resources to maintain and regularly upgrade our systems and processes that are designed to protect the security of our computer systems, software, networks, and other technology assets and the confidentiality, integrity, and availability of information belonging to us and our customers, there is no assurance that our security measures will provide absolute security. Further, to access our products and services our customers may use computers and mobile devices that are beyond our security control systems. In recent years, many financial institutions, including the Company, have been subjected to sophisticated and targeted attacks intended to obtain unauthorized access to confidential information, destroy data, disrupt or degrade service, sabotage systems or cause other damage, including through the introduction of computer viruses or malware, cyber attacks and other means and expect to be subject to such attacks in the future. Certain financial institutions and companies involved in data processing in the United States have also experienced attacks from technically sophisticated and well-resourced third parties that were intended to disrupt normal business activities by making internet banking systems inaccessible to customers for extended periods. These “denial-of-service” attacks have not breached our data security systems, but require substantial resources to defend, and may affect customer satisfaction and behavior.

Continued geographical turmoil, including the ongoing conflict between Russia and Ukraine, has heightened the risk of cyberattack and has created new risk for cybersecurity, and similar concerns. For example, the United States government has warned that sanctions imposed against Russia by the United States in response to its conflict with Ukraine could motivate Russia to engage in malicious cyber activities against the United States. If such cyberattacks occurred, it could result in severe costs and disruptions to governmental entities and companies and their operations. The impact of the conflict and retaliatory measures is continually evolving and cannot be predicted with certainty.

Despite our efforts to ensure the integrity of our systems, it is possible that we may not be able to anticipate or to implement effective preventive measures against all security breaches of these types, especially because the techniques used change frequently or are not recognized until launched, and because security attacks can originate from a wide variety of sources, including persons who are involved with organized crime or associated with external service providers or who may be linked to terrorist organizations or hostile foreign governments. Those parties may also attempt to fraudulently induce employees, customers or other users of our systems to disclose sensitive information in order to gain access to our data or that of our customers or clients. We have implemented employee and customer awareness training around phishing, malware, and other cyber risks, however there can no assurances that this training will be completely effective. These risks may increase in the future as we continue to increase our electronic payments and other internet-based product offerings and expand our internal usage of web-based products and applications.

If our security systems or those of our third party vendors, contractors and customers are penetrated or circumvented, it could cause serious negative consequences for us, including significant disruption of our operations, misappropriation or theft of our confidential information or that of our customers, or damage our computers or systems and those of our customers and counterparties, and could result in violations of applicable privacy and other laws, financial loss to us or to our customers, loss of confidence in our security measures, customer dissatisfaction, significant litigation exposure, and harm to our reputation, all of which could have a material adverse effect on us. If personal, confidential or proprietary information of customers or clients in the Bank’s or such vendors’ or other third-parties’ possession were to be mishandled or misused, we could suffer significant regulatory consequences, reputational damage and financial loss.

We may not be able to anticipate all security breaches, nor may we be able to implement guaranteed preventive measures against such security breaches. Additionally, a security breach may be difficult to detect, even after it occurs, which may compound the issues related to such breach.

For example, as previously disclosed in the Current Report 8-K filed by us on February 14, 2023, the Bank experienced a network security incident, where unusual network activity was detected, and management shut down all networked systems which prevented employees from accessing internal systems, data and telephones for a limited period of time. Upon discovering the incident, the Bank immediately launched an investigation and engaged a digital forensics firm to help determine the scope of the incident and identify potentially impacted data. In addition, the Bank promptly notified law enforcement and banking regulators about the incident. The Bank believes that its core banking systems, including those that facilitate loan or deposit related transactions, were not affected by this event as evidenced by the Bank’s general ability to resume customer facing operations within two days. However, the Bank’s internal system access as well as communication capabilities, including e-mail correspondence and telephones, required approximately one week of time for the restoration process to be completed in a safe and secure environment.

The Bank continues to work with third-party forensic investigators to understand the nature and scope of the incident and to determine what information may have been accessed and who may have been impacted. The investigation is on-going.

While we continue to evaluate the impact of this incident, we remain subject to risks and uncertainties as a result, including legal, reputational, and financial risks, the results of our ongoing investigation of this security incident, any potential regulatory inquiries and/or litigation to which we may become subject in connection with this incident, and the extent of remediation and other additional costs that may be incurred by us. To date, we do not believe such consequences are material, however the network security incident is still recent and the investigation is ongoing. Although we maintain insurance coverage, including cybersecurity insurance, the amount of coverage available may not cover all losses. We anticipate that we will incur additional expenses in future periods. Network breaches at other financial institutions have, in some instances, resulted in litigation, government investigations and other regulatory enforcement inquiries. Given the uncertainties about the impact of the incident and the inherent uncertainties involved in litigation, government investigations and regulatory

18 TriCo Bancshares 2022 10-K

enforcement decisions, there is significant uncertainty as to the ultimate liability and expense we may incur from these kinds of matters, if any. The finding, or even the assertion, of substantial legal liability against us and any regulatory enforcement actions could have a material adverse effect on our business and financial condition and could cause significant reputational harm to us, which could seriously harm our business. In addition, litigation, regulatory interventions, and media reports of perceived security vulnerabilities and any resulting damage to our reputation or loss of confidence in the security of our systems could adversely affect our business. As cyber threats continue to evolve, we have been and will likely continue to be required to expend significant resources to continuously enhance our protective measures and may be required to expend significant resources to investigate and remediate any information security vulnerabilities or incidents.

Our reliance on third-party vendors exposes us to risks, including additional cybersecurity risks.

Third-party vendors provide key components of our business infrastructure, including certain data processing and information services. On our behalf, third parties may transmit confidential, propriety information. Some of these third parties may engage vendors of their own, which introduces the risk that these "fourth parties" could be the source of operational and/or security failures. Although we require third-party providers and these fourth-party vendors to maintain certain levels of information security, such providers may remain vulnerable to breaches, unauthorized access, misuse, computer viruses, or other malicious attacks that could ultimately compromise sensitive information. While we may contractually limit our liability in connection with attacks against third-party providers, we remain exposed to the risk of loss associated with such vendors.

In addition, a number of our vendors are large national entities with dominant market presence in their respective fields. Their services could prove difficult to replace in a timely manner if a failure or other service interruption were to occur. Failures of certain vendors to provide contracted services could adversely affect our ability to deliver products and services to our customers and cause us to incur significant expense.

Our business is highly reliant on technology and our ability and our third-party service providers to manage the operational risks associated with technology.

Our business involves storing and processing sensitive consumer and business customer data. We depend on internal systems, third party service providers, cloud services and outsourced technology to support these data storage and processing operations. Despite our efforts to ensure the security and integrity of our systems, we may not be able to anticipate, detect or recognize threats to our systems or those of third-party service providers or to implement effective preventive measures against all cybersecurity breaches. Cyberattack techniques change regularly and can originate from a wide variety of sources, including third parties who are or may be involved in organized crime or linked to terrorist organizations or hostile foreign governments, and such third parties may seek to gain access to systems directly or using equipment or security passwords belonging to employees, customers, third-party service providers or other users of our systems. These risks may increase in the future as we continue to increase our mobile, digital and other internet-based product offerings and expands our internal usage of web-based products and applications. A cybersecurity breach or cyberattack could persist for a long time before being detected and could result in theft of sensitive data or disruption of our transaction processing systems.

Our inability to use or access these information systems at critical points in time could unfavorably impact the timeliness and efficiency of our business operations. A material breach of customer data security [such as a possible breach of customer data in connection with the network security incentive discussed above, may negatively impact our business reputation and cause a loss of customers, result in increased expense to contain the event and/or require that we provide credit monitoring services for affected customers, result in regulatory fines and sanctions and/or result in litigation. Cybersecurity risk management programs are expensive to maintain and will not protect us from all risks associated with maintaining the security of customer data and our proprietary data from external and internal intrusions, disaster recovery and failures in the controls used by our vendors.

Cybersecurity and data privacy are areas of heightened legislative and regulatory focus.

As cybersecurity and data privacy risks for banking organizations and the broader financial system have significantly increased in recent years, cybersecurity and data privacy issues have become the subject of increasing legislative and regulatory focus. The federal bank regulatory agencies have proposed enhanced cyber risk management standards, which would apply to a wide range of large financial institutions and their third-party service providers, including us, and would focus on cyber risk governance and management, management of internal and external dependencies, and incident response, cyber resilience and situational awareness. Several states have also proposed or adopted cybersecurity legislation and regulations, which require, among other things, notification to affected individuals when there has been a security breach of their personal data. For more information regarding cybersecurity regulation, refer to the “Supervision and Regulation” section of this report.

We receive, maintain and store non-public personal information of our customers and counterparties, including, but not limited to, personally identifiable information and personal financial information. The sharing, use, disclosure, and protection of this information are governed by federal and state law. Both personally identifiable information and personal financial information is increasingly subject to legislation and regulation, the intent of which is to protect the privacy of personal information that is collected and handled. For more information regarding data privacy regulation, refer to the “Supervision and Regulation” section of this report.

We may become subject to new legislation or regulation concerning cybersecurity or the privacy of personally identifiable information and personal financial information or of any other information we may store or maintain. We could be adversely affected if new legislation or regulations are adopted or if existing legislation or regulations are modified such that we are required to alter our systems or require changes to our business practices or privacy policies. If new or existing cybersecurity, data privacy, data protection, data transfer or data retention laws are implemented, interpreted or applied in a manner inconsistent with our current practices, including as a result of the network security incident discussed above, we may be subject to fines, litigation or regulatory enforcement actions or ordered to change our

19 TriCo Bancshares 2022 10-K

business practices, policies or systems in a manner that adversely impacts our operating results. In addition, any additional laws and regulatory enforcement measures will result in increased compliance costs.

A failure to implement technological advances could negatively impact our business.

The banking industry is undergoing technological changes with frequent introductions of new technology-driven products and services. In addition to improving customer services, the effective use of technology increases efficiency and enables financial institutions to reduce costs. Our future success will depend, in part, on our ability to address the needs of our customers by using technology to provide products and services that will satisfy customer demands for convenience as well as to create additional efficiencies in our operations. Many of our competitors have substantially greater resources than we do to invest in technological improvements. We may not be able to effectively implement new technology-driven products and services or successfully market such products and services to our customers. In addition, advances in technology such as digital, mobile, telephone, text, and online banking; e-commerce; and self-service automatic teller machines and other equipment, as well as changing customer preferences to access our products and services through digital channels, could decrease the value of our branch network and other assets. We may close or sell certain branches and restructure or reduce our remaining branches and work force. These actions could lead to losses on assets, expense to reconfigure branches and loss of customers in certain markets. As a result, our business, financial condition or results of operations may be adversely affected.

We can be negatively affected if we fail to identify and address operational risks associated with the introduction of or changes to products, services and delivery platforms.

When we launch a new product or service, introduce a new platform for the delivery or distribution of products or services (including mobile connectivity and cloud computing), or make changes to an existing product, service or delivery platform, it may not fully appreciate or identify new operational risks that may arise from those changes, or may fail to implement adequate controls to mitigate the risks associated with those changes. Any significant failure in this regard could diminish our ability to operate one or more of our businesses or result in:

•potential liability to clients, counterparties and customers;

•increased operating expenses;

•higher litigation costs, including regulatory fines, penalties and other sanctions;

•damage to our reputation;

•impairment of our liquidity;

•regulatory intervention; or

•weaker competitive standing.

Any of the foregoing consequences could materially and adversely affect our businesses and results of operations.

Our risk management framework may not be effective in identifying and mitigating every risk to us.

Any inadequacy or lapse in our risk management framework, governance structure, practices, models or reporting systems could expose it to unexpected losses, and our financial condition or results of operations could be materially and adversely affected. Any such inadequacy or lapse could:

•hinder the timely escalation of material risk issues to our senior management and the Board of Directors;

•lead to business decisions that have negative outcomes for us;

•require significant resources and time to remediate;

•lead to non-compliance with laws, rules and regulations;

•attract heightened regulatory scrutiny;

•expose us to regulatory investigations or legal proceedings;

•subject us to litigation or regulatory fines, penalties or other sanctions;

•harm our reputation; or

•otherwise diminish confidence in TriCo.

We rely on data to assess many of our various risk exposures. Any deficiencies in the quality or effectiveness of our data gathering, analysis and validation processes could result in ineffective risk management practices. These deficiencies could also result in inaccurate risk reporting.

General Risk Factors

20 TriCo Bancshares 2022 10-K

We depend on key personnel and the loss of one or more of those key personnel may materially and adversely affect our prospects.

Our future operating results depend substantially upon the continued service of our executive officers and key personnel. Our future operating results also depend in significant part upon our ability to attract and retain qualified management, financial, technical, marketing, sales and support personnel. Competition for qualified personnel is intense, and we cannot ensure success in attracting or retaining qualified personnel. There may be only a limited number of persons with the requisite skills to serve in these positions, and it may be increasingly difficult for us to hire personnel over time. Our business, financial condition or results of operations could be materially adversely affected by the loss of any of our key employees, or our inability to attract and retain skilled employees.

Our business could suffer if we fail to attract and retain skilled people.

Our success depends, in large part, on our ability to attract and retain key people. Competition for the best people in many activities engaged in by us is intense including with respect to compensation and emerging workplace practices, accommodations and remote work options, and we may not be able to hire people or to retain them. In addition, the transition to increased work-from-home arrangements, which is likely to survive the COVID-19 pandemic for many companies, may exacerbate the challenges of attracting and retaining talented and diverse employees as job markets may be less constrained by physical geography. Our current or future approach to in-office and work-from-home arrangements may not meet the needs or expectations of our current or prospective employees or may not be perceived as favorable as compared to the arrangements offered by competitors, which could adversely affect our ability to attract and retain employees.

Our previous results may not be indicative of our future results.

We may not be able to sustain our historical rate of growth and level of profitability or may not even be able to grow our business or continue to be profitable at all. Various factors, such as economic conditions, regulatory and legislative considerations and competition, may also impede or prohibit our ability to expand our market presence and financial performance. If we experience a significant decrease in our historical rate of growth, our results of operations and financial condition may be adversely affected due to a high percentage of our operating costs being fixed expenses.

Compliance with changing regulation of corporate governance and public disclosure may result in additional risks and expenses.

Changing laws, regulations and standards relating to corporate governance and public disclosure, including the Dodd-Frank Act, the Sarbanes-Oxley Act of 2002 and new SEC regulations, have created additional expense for publicly traded companies such as the Company. The application of these laws, regulations and standards may evolve over time as new guidance is provided by regulatory and governing bodies, which could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices. We are committed to maintaining high standards of corporate governance and public disclosure. As a result, our efforts to comply with evolving laws, regulations and standards have resulted in, and are likely to continue to result in, increased expenses and a diversion of management time and attention. In particular, our efforts to comply with Section 404 of the Sarbanes-Oxley Act of 2002 and the related regulations regarding management’s required assessment of its internal control over financial reporting and our external auditors’ audit of our internal control over financial reporting requires, and will continue to require, the commitment of significant financial and managerial resources. Further, the members of our board of directors, members of our audit or compensation and management succession committees, our chief executive officer, our chief financial officer and certain other executive officers could face an increased risk of personal liability in connection with the performance of their duties. It may also become more difficult and more expensive to obtain director and officer liability insurance. As a result, our ability to attract and retain executive officers and qualified board and committee members could be more difficult.

Tax regulations could be subject to potential legislative, administrative or judicial changes or interpretations.

Federal income tax treatment of corporations may be clarified and/or modified by legislative, administrative or judicial changes or interpretations at any time. Given the current economic and political environment, and ongoing budgetary pressures, the enactment of new federal or state tax legislation or new interpretations of existing tax laws could occur. The enactment of such legislation, or changes in the interpretation of existing law may have a material adverse effect on our financial condition, results of operations, and liquidity.

In the normal course of business, we are routinely subjected to examinations and audits from federal, state, and local taxing authorities regarding tax positions taken by us and the determination of the amount of tax due. These examinations may relate to income, franchise, gross receipts, payroll, property, sales and use, or other tax returns. The challenges made by taxing authorities may result in adjustments to the amount of taxes due, and may result in the imposition of penalties and interest. If any such challenges are not resolved in our favor, they could have a material adverse effect on our financial condition, results of operations, and liquidity.

Claims, litigation, government investigations, and other proceedings may adversely affect our business and results of operations

As a community financial institution, we are at times subject to actual and threatened claims, litigation, reviews, investigations, and other proceedings, including proceedings by governments and regulatory authorities, involving a wide range of issues, including labor and employment, data protection, data security, network security, consumer protection, commercial disputes, goods and services offered by us and by third parties, and other matters. Any of these types of proceedings can have an adverse effect on us because of legal costs, disruption of our operations, diversion of management resources, negative publicity, and other factors. The outcomes of these matters are inherently unpredictable and subject to significant uncertainties. Determining legal reserves for possible losses from such matters involves judgment and may not reflect the full range of uncertainties and unpredictable outcomes. Until the final resolution of such matters, we may be exposed to losses in excess of the amount recorded, and such amounts could be material. Should any of our estimates and assumptions

21 TriCo Bancshares 2022 10-K

change or prove to have been incorrect, it could have a material effect on our business, financial condition and results of operations. In addition, it is possible that a resolution of one or more such proceedings, including as a result of a settlement, could involve licenses, sanctions, consent decrees, or orders requiring us to make substantial future payments, preventing us from offering certain products or services, requiring us to change our business practices in a manner materially adverse to our business, requiring development of non-infringing or otherwise altered products or technologies, damaging our reputation, or otherwise having a material effect on our operations.

Climate change could have a material negative impact on us and our clients.

Our business, as well as the operations and activities of our clients, could be negatively impacted by climate change. Climate change presents both immediate and long-term risks to us and our clients, and these risks are expected to increase over time. Climate change presents multi-faceted risks, including: operational risk from the physical effects of climate events on the us and our clients’ facilities and other assets; credit risk from borrowers with significant exposure to climate risk; transition risks associated with the transition to a less carbon-dependent economy; and reputational risk from stakeholder concerns about our practices related to climate change, our carbon footprint, and our business relationships with clients who operate in carbon-intensive industries.

Federal and state banking regulators and supervisory authorities, investors, and other stakeholders have increasingly viewed financial institutions as important in helping to address the risks related to climate change both directly and with respect to their clients, which may result in financial institutions coming under increased pressure regarding the disclosure and management of their climate risks and related lending and investment activities. Given that climate change could impose systemic risks upon the financial sector, either via disruptions in economic activity resulting from the physical impacts of climate change or changes in policies as the economy transitions to a less carbon-intensive environment, we may face regulatory risk of increasing focus on our resilience to climate-related risks, including in the context of stress testing for various climate stress scenarios. Ongoing legislative or regulatory uncertainties and changes regarding climate risk management and practices may result in higher regulatory, compliance, credit, and reputational risks and costs.

With the increased importance and focus on climate change, we are making efforts to enhance our governance of climate change-related risks and integrate climate considerations into our risk governance framework. Nonetheless, the risks associated with climate change are rapidly changing and evolving in an escalating fashion, making them difficult to assess due to limited data and other uncertainties. We could experience increased expenses resulting from strategic planning, litigation, and technology and market changes, and reputational harm as a result of negative public sentiment, regulatory scrutiny, and reduced investor and stakeholder confidence due to our response to climate change and our climate change strategy, which, in turn, could have a material negative impact on our business, results of operations, and financial condition.

ITEM 7.    MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Introduction

The following discussion and analysis is designed to provide a better understanding of the significant changes and trends related to the Company and the Bank’s financial condition, operating results, asset and liability management, liquidity and capital resources and should be read in conjunction with the consolidated financial statements of the Company and the related notes at Item 8 of this report.

In March 2022, the Company closed the acquisition of Valley Republic Bancorp. Historical periods prior to March 25, 2022 reflect results of legacy Trico Bancshares operations. Subsequent to closing, results reflect all post-acquisition activity. For further information, refer to Note 2 “Business Combinations” of the Notes to Consolidated Financial Statements.

Financial Overview

In 2022, the Company reported net income of $125,419,000, a $7,764,000 or 6.6% increase from the prior year. Earnings per share on a diluted basis for the year were $3.83, down 2.8% from the prior year. The current year net income reported was negatively impacted by acquisition-related expenses totaling $6,253,000, compared to $1,523,000 in the prior year. In 2022, net interest income was reported at $345,976,000, an increase of $74,437,000 or 27.4% from the prior year.

Net interest income on a fully tax equivalent (FTE) basis, a non-GAAP financial measure, was $347,536,000, an increase of $74,926,000, or 27.4%, from 2021. The increase in FTE net interest income reflected the benefit of a $1,352,778,000, or 17.8%, increase in average earning assets in addition to a 30 basis point increase in the FTE net interest marign to 3.88%. Average earning asset growth included an $990,559,000, or 20.3%, increase in average loans and leases and an $573,720,000, or 26.3%, increase in average securities. Average

25 TriCo Bancshares 2022 10-K

balances across earning asset categories reflect organic growth in addition to the late first quarter 2022 VRB acquisition. The increase in average securities was additionally driven by the redeployment of excess liquidity into securities in the first half of 2022. The net interest margin expansion was driven by the higher rate environment driving an increase in loan and lease and investment security yields, partially offset by higher cost of funds and the impact of lower accelerated PPP loan fees recognized upon forgiveness payments from the SBA in 2022.

The provision for credit losses increased $25,245,000 to $18,470,000, primarily due to the acquisition of VRB and organic loan and lease growth. The allowance for credit losses (ACL) was $105,680,000, or 1.64% of total loans and leases, at December 31, 2022, compared to $85,376,000, or 1.74% of total loans and leases, at December 31, 2021. The increase in the total ACL was primarily driven by loan and lease growth, while the overall risk profile of the loan portfolio continued to improve despite management's observation of future recessionary risks.

Noninterest income was $63,046,000, down $618,000, or 1%, from the prior year. Noninterest expense was $216,645,000, up $38,370,000, or 21.5%, from the prior year. The changes in noninterest income and noninterest expense were impacted by the VRB acquisition, completed in March 2022. Noninterest income was additionally negatively impacted by a decline in gain on sale of mortgage loans totaling of $7,238,000, to $2,342,000 for the 2022 year.

The tangible common equity to tangible assets ratio, a non-GAAP financial measure, was 7.6% at December 31, 2022, down 161 basis points from December 31, 2021, primarily due to a decrease in tangible common equity related to elevated interest rates causing an increase in accumulated other comprehensive loss, partially offset by the retention of earnings.

Management believes that tangible equity is meaningful because it is a measure that the Company and investors commonly use to assess capital adequacy. Tangible book value is calculated by dividing tangible equity by shares outstanding at period end.

As TriCo Bancshares has not commenced any business operations independent of 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 and net interest income may be presented on a fully tax-equivalent (FTE) basis. The presentation of interest income and net interest income 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 within Item 7 and Item 8 of this report, 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

In preparing the consolidated financial statements in accordance with generally accepted accounting principles in the United States of America (GAAP), management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and revenues and expenses for the period. Actual results could differ significantly from those estimates.     Our most significant accounting policies and estimates and their related application are discussed below.

Allowance for Credit Losses

The Company’s method for assessing the appropriateness of the allowance for credit losses includes specific allowances for individually analyzed loans, formula allowance factors for pools of credits, and qualitative considerations which include, among other things, current and forecast economic and environmental factors (e.g., interest rates, growth, economic conditions, etc.). Allowance factors for loan pools were based on historical loss experience by product type and prior risk rating.

Management estimates the ACL 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 has 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 current expected credit 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, the pace of change in corporate bond yields, and U.S. gross domestic product.

There is a greater chance that the Company would suffer a loss from a loan that was risk rated less than satisfactory than if the loan was last graded satisfactory. As such, the proper risk grading of loans in the portfolio is important to the determination of the calculation of and determination of adequacy of the allowance for credit losses. Utilizing the historical loss data described above, the Company applies reserve rates within any unique pool based on its loss and risk grade migration. Therefore, within any given pool, a larger loss estimation factor is applied to less than satisfactory loans as compared to those that the Company last graded as satisfactory. The resulting allowance for any pool is the sum of the calculated reserves determined in this manner.

Certain loans are not included in pools of loans that are collectively evaluated. The segregation of these loans is based on the results from analysis of identified credits that meet management’s criteria for specific evaluation. These loans are first reviewed individually to determine if such loans have a unique risk profile that would warrant individual evaluation. Loans where management has concluded that it is probable that the borrower will be unable to pay all amounts due under the original contractual terms are removed from the pools of loans collectively evaluated. They are then specifically reviewed and evaluated individually by management for loss potential by evaluating sources of repayment, including collateral as applicable, and a specified allowance for credit losses is established where necessary. By definition, any loan that management has placed on non-accrual is required to be individually evaluated, however, not all individually evaluated loans need be placed on non-accrual.

Because current economic conditions and forecasts can change and future events make it inherently difficult to predict the anticipated amount of estimated credit losses on loans, management's determination of the appropriateness of the ACL, could change significantly. It is difficult to estimate how potential changes in any one economic factor or input might affect the overall allowance because a wide variety of factors and inputs are considered in estimating the allowance and changes in those factors and inputs considered may not occur at the same rate and may not be consistent across all product types. Additionally, changes in factors and inputs may move independently of one another, such that improvement in one or certain factors may offset deterioration in others. Management believes that the ACL was adequate as of December 31, 2022.

Other Accounting Policies and Estimates

On an on-going basis, the Company evaluates its estimates, including those that materially affect the financial statements and are related to investments, mortgage servicing rights, fair value measurements, retirement plans, intangible assets and the fair value of acquired assets and liabilities. 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. The Company’s policies related to these estimates can be found in Note 1 in the financial statements at Item 8 of this report.

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.

Results of Operations

Average balances, including 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, certain performance measures including interest income, net interest income, net interest yield, and efficiency ratio are generally presented on a fully tax-equivalent (FTE) basis. The Company believes the use of these non-generally accepted accounting principles (non-GAAP) measures provides additional clarity in assessing its results.

Net Interest Income

Net interest income is our largest source of revenue and is the difference between the interest earned on interest-earning assets (generally loans, leases and investment securities) and the interest expense incurred in connection with interest-bearing liabilities (generally deposits and borrowed funds). The level of net interest income is primarily a function of the difference between the effective yield on our average interest-earning assets and the effective cost of our interest-bearing liabilities. These factors are influenced by the pricing and mix of interest-earning assets and interest-bearing liabilities which, in turn, are impacted by external factors such as local economic conditions, competition for loans and deposits, the monetary policy of the FRB and market interest rates. For further discussion, refer to “—Risk Factors – Risks Related to Interest Rates.” Following is a summary of the Company’s net interest income for the periods indicated (dollars in thousands):

	Year ended December 31,
	2022			2021			2020
Interest income	$	355,505		$	277,047		$	267,184
Interest expense	(9,529)			(5,508)			(9,457)
Net interest income (not FTE)	345,976			271,539			257,727
FTE adjustment	1,560			1,071			1,069
Net interest income (FTE)	$	347,536		$	272,610		$	258,796
Net interest margin (FTE)	3.88		%	3.58		%	3.96		%
Acquired loans discount accretion:
Purchased loan discount accretion	$	5,465		$	8,091		$	8,171
Effect on average loan yield	0.09		%	0.17		%	0.19		%
Effect of purchased loan discount accretion on net interest margin (FTE)	0.06		%	0.11		%	0.13		%

Net interest income (FTE) during the year ended December 31, 2022 increased $74,926,000 or 27.5% to $347,536,000 compared against $272,610,000 during the year ended December 31, 2021. The increased amount of net interest income reflects growth in both total average loan and investment balances outstanding and the correlated yields, during 2022. Average loan balances, inclusive of acquisitions, increased by $1,496,541,000 or 30.4% from December 31, 2021. The yield on interest earning assets was 3.98% and 3.65% for the years ended December 31, 2022 and 2021, respectively. This 33 basis point increase in total earning asset yield was primarily attributable to a 11 basis point decrease in total loan yields and a 85 basis point increase in yields on total investments. Of the 11 basis point decrease in yields on loans, a 3 basis point decline was attributable to decreases in market rates, as well as an 8 basis point benefit from the accretion of purchased loans. The costs of total interest bearing liabilities increased 6 basis points to 0.19% during the year ended December 31, 2022, as compared to 0.13% for the year ended December 31, 2021. During the same period, costs associated with interest bearing deposits increased by 2 basis points to 0.10% as compared to 0.08% in the prior year. The increase in interest expense for the year ended December 31, 2022, as compared to the trailing year, was due largely to the increased rate environment for both the interest-bearing deposit expense and other borrowings interest expense.

Net interest income (FTE) during the year ended December 31, 2021 increased $13,814,000 or 5.3% to $272,610,000 compared against $258,796,000 during the year ended December 31, 2020. The increase amount of net interest income reflects growth in total average loan balances outstanding during 2021, which increased by $229,796,000 or 4.9% from December 31, 2020. The yield on interest earning assets was 3.65% and 4.11% for the years ended December 31, 2021 and 2020, respectively. This 46 basis point decrease in total earning asset yield was primarily attributable to a 23 basis point decrease in non-PPP loan yields and a 66 basis point decrease in yields on total investments. Of the 23 basis point decrease in yields on loans, a 21 basis point decline was attributable to decreases in market rates, in addition to 2 basis points from the accretion of purchased loans. The costs of total interest bearing liabilities decreased 12 basis points to 0.13% during the year ended December 31, 2021, as compared to 0.25% for the year ended December 31, 2020. During the same period, costs associated with interest bearing deposits decreased by 10 basis points to 0.08% as compared to 0.18% in the prior year. The decrease in interest expense for the year ended December 31, 2021, as compared to the trailing year, was due largely to the decreased rate environment benefiting both the interest-bearing deposit expense and other borrowings interest expense.

Provision for Credit Losses

The provision for credit losses during any period is the sum of the allowance for credit losses required at the end of the period and any net charge-offs during the period, less the allowance for credit losses required at the beginning of the period, and less any recoveries during the period. See the Tables labeled “Allowance for Credit Losses – December 31, 2022 and 2021” at Note 5 in Item 8 of Part II of this report for the components that make up the provision for credit losses for the years ended December 31, 2022 and 2021.

The Company recorded a provision for credit losses of $18,470,000 during the year ended December 31, 2022, versus a reversal of credit losses totaling $6,775,000 during the trailing year end. The increase in required provisioning during 2022 was largely attributed to the $10,820,000 in day 1 required reserves from loans acquired in connection with the VRB merger in the first quarter of 2022. Additionally, the Company designated certain loans and leases purchased from VRB as PCD, which required $2,037,000 in additional credit reserves as of the acquisition date. For PCD loans and leases, the initial estimate of expected credit losses is recognized in the ACL on the date of acquisition using the same methodology as other loans and leases held-for-investment. The remaining increase in the allowance for credit reserves was the result of changes in loan volume and changes in credit quality associated with levels of classified, past due and non-performing loans in addition to changes in qualitative factors.

The Company recorded a reversal of credit loses of $6,775,000 during the year ended December 31, 2021, versus a provision for credit losses totaling $42,813,000 during the trailing year end. The decrease in required provisioning during 2021 was attributed to improvement in both external economic indicators and the Company's internal credit risk assessment under the cohort method including changes in the level of past due and nonperforming loans. Declines in California unemployment levels, reduced concentration risks and an improved gross domestic product outlook contributed to total required qualitative reserves of $59,855,000 as of December 31, 2021, a decline of $2,080,000 or 3.4% from December 31, 2020. Quantitative reserves calculated using the Company's cohort loss model totaled $25,521,000 at December 31, 2021, a decline of $4,391,000 or 14.7% from the trailing period December 31, 2020.

Net recoveries for the year ended December 31, 2022 totaled $322,000 as compared to $694,000 for the year ended December 31, 2021. Total nonperforming loans declined by 28 basis points to 0.33% of total loans at December 31, 2022 from 0.61% of total loans at December 31, 2021. For further details of the change in nonperforming loans during the period ended December 31, 2022 see the Tables, and associated narratives, labeled “Changes in nonperforming assets during the year ended December 31, 2022” and “Changes in nonperforming assets during the three months ended December 31, 2022” under the heading “Asset Quality and Non-Performing Assets” below.

The following table summarizes the components of the provision for (benefit to) credit losses during the periods indicated (dollars in thousands):

	Year ended December 31,
(dollars in thousands)	2022		2021		2020
Provision (benefit) to allowance for credit losses	$	17,945	$	(7,165)	$	42,188
Change in reserve for unfunded loan commitments	525		390		625
Total provision for (benefit to) credit losses	$	18,470	$	(6,775)	$	42,813

The provision for credit losses is based on management’s evaluation of inherent risks in the loan portfolio and a corresponding analysis of the allowance for credit losses. Additional discussion on loan quality, our procedures to measure loan impairment, and the allowance for credit losses is provided under the heading “Asset Quality and Non-Performing Assets” below.

Non-interest Income

The following table summarizes the Company’s non-interest income for the periods indicated (dollars in thousands):

Total other non-interest income	13,281		19,716		17,213
Total non-interest income	$	63,046	$	63,664	$	55,194

Non-interest income decreased by $618,000 or 1.0% to $63,046,000 during the twelve months ended December 31, 2022, compared to $63,664,000 during the same period ended December 31, 2021. Generally, the increases in recurring non-interest income service charges and fees reflected during 2022 is the result of the VRB merger closing in March of 2022, and therefore, not reflected in 2021 operating results. As an offset, increases in interest rates during 2022 led to significant declines in mortgage lending related activity, resulting in a decrease of $7,238,000 in gain from the sale of loans, as compared to the trailing year then ended.

Non-interest income increased by $8,470,000 or 15.3% to $63,664,000 during the twelve months ended December 31, 2021, compared to $55,194,000 during the same period ended December 31, 2020. ATM and interchange fees improved $3,696,000 or 17.1% as a result of increased use due to relaxed social distancing guidelines during the year ended December 31, 2021 when compared to the same period in the prior year. Additionally, during the year ended 2020, there was substantial downward pressure on interest rates following the COVID-19 pandemic, resulting in a decline in the fair value of mortgage servicing rights totaling $2,634,000 during the period. Other non-interest income increased $1,574,000 during the twelve months ended December 31, 2021, largely attributed to an increase of $804,000 in the change of fair value of non-readily marketable equity investments and a $204,000 increase in proceeds from life insurance, respectively, as compared to the trailing 12 months ended.

Non-interest expense increased by $38,370,000 (21.5%) to $216,645,000 during the year ended December 31, 2022 as compared to $178,275,000 for the trailing twelve month period. Generally, the increases in recurring non-interest expenses and FTEs during 2022 is the result of the VRB merger closing in March of 2022, and therefore, not reflected in 2021 operating results.

Salaries and benefit expense decreased $5,770,000 (5.1%) to $129,852,000 during the year ended December 31, 2021 as compared to $106,351,000 for the trailing twelve month period. Base salaries, net of deferred loan origination costs remained nearly flat, decreasing by $320,000 (0.4%) to $84,861,000 due to a decrease in average full time equivalent employees to 1,039 from 1,093 in the prior year-to-date period, offset by a higher average wage per employee due to both, the addition of personnel with elevated technical skillets to adhere to elevated regulatory expectations and annual merit increases. Commissions and incentive compensation increased $4,935,000 (49.2%) to $14,957,000 during 2021 compared to 2020 primarily due to increased organic non-PPP loan originations as borrower interaction and business demands for loans improved following the disruption from COVID-19 and related mandates in 2020. Benefits and other compensation costs decreased by $10,385,000 (32.5%) to $21,550,000 during the year ended December 31, 2021 as compared to $31,935,000 for the trailing twelve month period, caused by declines in expenses associated with retirement obligations and insurance costs.

Merger and acquisition expenses associated with our 2022 acquisition of VRB totaled $1,523,000 during the year ended December 31, 2021 and $6,253,000 in 2022. Further, during the year ended December 31, 2021, expenses totaling approximately $1,745,000 are attributable to the Company's recently opened loan production offices, of which approximately $1,430,000 relates to salaries and benefits.

During 2018, the FDIC's Deposit Insurance Fund's (DIF) reserves exceeded the minimum set by the Dodd-Frank Act and the Company, with total assets less than $10 billion, was entitled to receive credits to offset a portion of its assessments. As a result, during the year ended December 31, 2020, the Bank received credits of $610,000, which contributed to the lower regulatory assessments and insurance expense during the period. There were no credits provided to the Bank during 2021 or 2022.

The provisions for income taxes applicable to income before taxes for the years ended December 31, 2022, 2021 and 2020 differ from amounts computed by applying the statutory Federal income tax rates to income before taxes. The effective tax rate and the statutory

33 TriCo Bancshares 2022 10-K

federal income tax rate are reconciled as follows:

	Year Ended December 31,
	2022		2021		2020
Federal statutory income tax rate	21.0	%	21.0	%	21.0	%
State income taxes, net of federal tax benefit	7.9		7.9		7.7
Tax-exempt interest on municipal obligations	(0.7)		(0.5)		(0.9)
Tax-exempt life insurance related income	(0.4)		(0.5)		(0.8)
Low income housing and other tax credits	(3.7)		(2.6)		(4.8)
Low income housing tax credit amortization	3.6		2.2		4.1
Compensation and benefits	(0.2)		(0.1)		0.4
Non-deductible merger expenses	0.1		0.1		—
Other	0.3		0.6		(0.9)
Effective Tax Rate	27.9	%	28.1	%	25.8	%

The effective tax rate on income was 27.9%, 28.1%, and 25.8% in 2022, 2021, and 2020, respectively. The effective tax rate was greater than the Federal statutory rates of 21% due to the combination of state tax expenses of 7.9% in 2022, 7.9% in 2021, and 7.7% in 2020. These increases in tax expense were partially offset by Federal tax-exempt interest income of $5,462,000, $3,069,000, and $3,566,000, respectively, Federal and State tax-exempt income of $3,167,000, $3,478,000, and $3,447,000, respectively, from increase in cash value and gain on death benefit of life insurance, low income housing tax credits and losses, net of amortization of $192,000, $620,000, and $619,000, respectively, and equity compensation excess tax benefits, net of non-deductible compensation of $1,966,000, $1,495,000, and $403,000, respectively. The low-income housing tax credits and the equity compensation excess tax benefits represent direct reductions in tax expense. In addition, the 2020 Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) provided the Company with an opportunity to file amended federal tax returns and generate refunds of approximately $805,000 during the year ended December 31, 2020. The items noted above resulted in an effective combined Federal and State income tax rate that differed from the combined Federal and State statutory income tax rate of approximately 29.6% during the three years ended 2022, 2021 and 2020.

Financial Condition

Restricted Equity Securities

Restricted equity securities were $17,250,000 at December 31, 2022 and December 31, 2021. The entire balance of restricted equity securities at December 31, 2022 and 2021 represents the Bank’s investment in the Federal Home Loan Bank of San Francisco (“FHLB”).

FHLB stock is carried at par and does not have a readily determinable fair value. While technically these are considered equity securities, there is no market for the FHLB stock. Therefore, the shares are considered as restricted investment securities. Management periodically evaluates FHLB stock for other-than-temporary impairment. Management’s determination of whether these investments are impaired is based on its assessment of the ultimate recoverability of cost rather than by recognizing temporary declines in value. The determination of whether a decline affects the ultimate recoverability of cost is influenced by criteria such as (1) the significance of any decline in net assets of the FHLB as compared to the capital stock amount for the FHLB and the length of time this situation has persisted, (2) commitments by the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLB, (3) the impact of legislative and regulatory changes on institutions and, accordingly, the customer base of the FHLB, and (4) the liquidity position of the FHLB.

As a member of the FHLB system, the Bank is required to maintain a minimum level of investment in FHLB stock based on specific percentages of its outstanding mortgages, total assets, or FHLB advances. The Bank may request redemption at par value of any stock in excess of the minimum required investment. Stock redemptions are at the discretion of the FHLB.

Loans

The Bank concentrates its lending activities in four principal areas: real estate mortgage loans (residential and commercial loans), consumer loans, commercial loans (including agricultural loans), and real estate construction loans.  The interest rates charged for the loans made by the Bank vary with the degree of risk, the size and maturity of the loans, the borrower’s relationship with the Bank and prevailing money market rates indicative of the Bank’s cost of funds.

The majority of the Bank’s loans are direct loans made to individuals, farmers and local businesses. The Bank relies substantially on local promotional activity and personal contacts by bank officers, directors and employees to compete with other financial institutions. The Bank 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.

At December 31, 2022, loans including net deferred loan costs, totaled $6,450,447,000 which was a 31.2% ($1,533,823,000) increase over the balance at the end of December 31, 2021. At December 31, 2021 loans, including net deferred loan costs, totaled $4,916,624,000 which was a 3.2% ($153,497,000) increase over the balances at the end of 2020. At December 31, 2020 loans, including net deferred loan costs, totaled $4,763,127,000 which was a 10.6% ($455,761,000) increase over the balances at the end of 2019.

In March 2020, the Small Business Administration ("SBA") Paycheck Protection Program ("PPP") was created to help small businesses keep workers employed during the COVID-19 crisis. As a SBA Preferred Lender, the Company was able to provide PPP loans to small business customers. The SBA ended PPP and did not accept new borrowing applications, effective May 31, 2021.

As of December 31, 2022 and 2021, the total gross balances outstanding of PPP loans was $1,617,000 and $63,311,000, respectively, as compared to total PPP originations of $640,410,000. In connection with the origination of these loans, the Company earned approximately $25,299,000 in loan fees, offset by deferred loan costs of approximately $1,245,000, the net of which will be recognized over the earlier of loan maturity (between 24-60 months), repayment or receipt of forgiveness confirmation. As of December 31, 2022, nearly all PPP loans originated have been forgiven and repaid by the SBA and there was approximately $15,000 in net deferred fee income remaining to be recognized. During the year ended December 31, 2022, the Company recognized approximately $2,149,000 in fees on PPP loans as compared with $14,148,000 for the year ended December 31, 2021.

From time to time the Bank may be presented with the opportunity to purchase individual or pools of loans in whole or in part outside of a transaction that would be considered a business combination. As of December 31, 2022 and 2021, the outstanding carrying value of purchased loans that were not acquired in a business combination totaled $167,014,000 and $159,373,000, respectively.

Nonperforming assets increased during the fourth quarter of 2022 by $3,848,000 (18.4%) to $24,760,000 at December 31, 2022 compared to $20,912,000 at September 30, 2022. The increase in nonperforming assets during the fourth quarter of 2022 was the result of new nonperforming loans of $10,186,000, that were partially offset by net paydowns, sales or upgrades of nonperforming loans to performing status totaling $6,044,000, and net charge-offs of $73,000 in non-performing loans. The current quarter change in non-performing assets is nearly entirely attributed to a single CRE relationship, which is considered well-secured as of the current period end.

Nonperforming assets increased during the fourth quarter of 2021 by $1,504,000 (4.8%) to $32,944,000 at December 31, 2020 compared to $31,440,000 at September 30, 2021. The increase in nonperforming assets during the fourth quarter of 2021 was the result of new nonperforming loans of $3,858,000, that were partially offset by net paydowns, sales or upgrades of nonperforming loans to performing status totaling $1,690,000, dispositions of foreclosed assets totaling $559,000, and net charge-offs of $105,000 in non-performing loans.

The $3,858,000 in new nonperforming loans during the fourth quarter of 2021 was comprised of, most notably, an increase of $1,992,000 and $1,633,000, respectively, on separate farmland relationships, both of which have been individually evaluated for collectability under the collateral methodology. Reserves of approximately $275,000 have been recorded in connections with these relationships has been recorded as of December 31, 2021.

Allowance for Credit Losses - Investment Securities

The Company evaluates available for sale debt securities in an unrealized loss position to determine whether the decline in the fair value below the amortized cost basis (impairment) is due to credit-related factors or noncredit-related factors. Any impairment that is not credit related is recognized in other comprehensive income, net of applicable taxes. Credit-related impairment is recognized as an allowance for credit losses on the balance sheet, limited to the amount by which the amortized cost basis exceeds the fair value, with a corresponding adjustment to earnings. Both the allowance for credit losses and the adjustment to net income may be reversed if conditions change. However, if the Company intends to sell an impaired available for sale debt security or more likely than not will be required to sell such a security before recovering its amortized cost basis, the entire impairment amount is recognized in earnings with a corresponding adjustment to the security's amortized cost basis. During the years ended December 31, 2022 and 2021, no allowance for credit losses nor impairment recognized in earnings related to available for sale investment securities was recorded.

Allowance for Credit Losses - Held to Maturity Investment Securities

In addition to credit losses associated with the Company's loan portfolio, the CECL standard requires that loss estimates be developed for securities classified as held-to-maturity (HTM). As of December 31, 2022, the Company's HTM investment portfolio had a carrying value of approximately $160,983,000 and was comprised of $154,830,000 in obligations backed by U.S. government agencies and $6,153,000 in obligations of states and political subdivisions. As the 96.1% of the HTM portfolio consisted of investment securities where payment performance has an implicit or explicit guarantee from the U.S. government and where no history of credit losses exist, management believes that indicators for zero loss are present and therefore, no loss reserves were recognized in conjunction with the adoption of the CECL standard. Further, management 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. Based on this evaluation, management determined that the expected credit losses associated with these securities is less than significant for financial reporting purposes. Therefore, during the year ended December 31, 2022 no allowance for credit losses related to HTM securities was recorded.

Allowance for Credit Losses - 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 the estimated time of default. While the provision for credit losses associated with unfunded commitments is included in "provision for (benefit from) credit losses" on the consolidated statement of income, the reserve for unfunded commitments is maintained on the consolidated balance sheet in other liabilities.

Ratio of allowance for credit losses to gross loans	1.64		%	1.74		%	1.93		%	0.71		%	0.81		%

Based on the current conditions of the loan portfolio, management believes that the $105,680,000 allowance for credit losses at December 31, 2022 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.

The credit quality of the Company’s loan portfolio, as measured by trends in the volume of past due loans, non-accrual loans, net loan charge-offs (recoveries) and risk grades, remained stable throughout the year. On a year over year basis, improved trends in the actual and forecasted levels of unemployment and GDP further contributed to the lower ratio of credit reserves as a percentage of total loans outstanding. One notable exception to the improved qualitative reserves was caused by the observed volatility and increase in corporate debt yields, signaling greater risk of default.

The allowance for credit losses increased by $20,304,000 during the year ended December 31, 2022 which is primarily reflective of the acquisition of VRB during March 2022, organic growth within the loan portfolio improvement in both the Company's qualitative and quantitative factors, and increase in reserve on individually analyzed loans. Ex-growth in loans outstanding, quantitative factors from the cohort model improved slightly during the year as a result of continued improvement in the Company's loss experience as a percentage of

total loans outstanding; 2) reductions in past due loans, and 3) avoidance of loan concentrations. However, specific reserves did increase by $1,432,000 as compared to the previous year end, but still remain at historically modest levels.

As compared to historical norms, inflation remains elevated from continued disruptions in the supply chain, wage pressures, and higher living costs such as housing and food prices Despite the expected continued benefit to the net interest income of the Company from the elevated rate environment, Management notes the rapid intervals of rate increases by the Federal Reserve and inversion of the yield curve, have boosted expectations of the US entering a recession within 12 months and has led to the lowest levels of consumer sentiment in decades. As a result, management continues to believe that certain credit weakness are likely present in the overall economy and that it is appropriate to cautiously maintain a reserve level that incorporates such risk factors.

Market Risk Management

Overview. The goal for managing the assets and liabilities of the Bank is to maximize shareholder value and earnings while maintaining a high quality balance sheet without exposing the Bank to undue interest rate risk. The Board of Directors has overall responsibility for the Company’s interest rate risk management policies. The Bank has an Asset and Liability Management Committee which establishes and monitors guidelines to control the sensitivity of earnings and the fair value of certain assets and liabilities as may be caused by changes in interest rates. The Company does not hold any financial instruments that are not maintained in US dollars and is not party to any contracts that may be settled or repaid in a denomination other than US dollars.

Asset/Liability Management. Activities involved in asset/liability management include but are not limited to lending, accepting and placing deposits, investing in securities and issuing debt. Interest rate risk is the primary market risk associated with asset/liability management. Sensitivity of earnings to interest rate changes arises when yields on assets change in a different time period or in a different amount from that of interest costs on liabilities. To mitigate interest rate risk, the structure of the balance sheet is managed with the goal that movements of interest rates on assets and liabilities are correlated and contribute to earnings even in periods of volatile interest rates. The asset/liability management policy sets limits on the acceptable amount of variance in net interest margin and market value of equity under changing interest environments. Market value of equity is the net present value of estimated cash flows from the Bank’s assets, liabilities and off-balance sheet items. The Bank uses simulation models to forecast net interest margin and market value of equity.

Simulation of net interest margin and market value of equity under various interest rate scenarios is the primary tool used to measure interest rate risk. The Bank estimated the potential impact of changing interest rates on net interest margin and market value of equity using computer-modeling techniques. A balance sheet forecast is prepared using inputs of actual loan, securities and interest-bearing liability (i.e. deposits/borrowings) positions as the beginning base.

43 TriCo Bancshares 2022 10-K

In the simulation of net interest income and market value of equity, the forecast balance sheet is processed against various interest rate scenarios. These various interest rate scenarios include a flat rate scenario, which assumes interest rates are unchanged in the future, and rate ramp and or shock scenarios including -300, -200, -100, +100, +200, and +300 basis points around the flat scenario. At December 31, 2022, the overnight Federal funds rate, the rate primarily used in these interest rate shock scenarios, was 4.25%. 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 shock scenario over a twelve month period utilizing the Company's specific mix of interest earning assets and interest bearing liabilities as of December 31, 2022.

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)	(2.5)	%	(4.1)	%
+200 (shock)	(1.7)	%	(2.4)	%
+100 (shock)	(0.7)	%	(0.3)	%
+    0 (flat)	—		—
-100 (shock)	(2.2)	%	(3.9)	%
-200 (shock)	(6.5)	%	(12.9)	%
-300 (shock)	(9.9)	%	(26.1)	%

These simulations indicate that given a “flat” balance sheet size scenario, and if interest-bearing checking, savings and money market interest rates track the general interest rate changes by the rate shock values listed above, the Company’s balance sheet is slightly liability sensitive over a twelve month time horizon for both a rates up and rates down shock scenario. “Asset sensitive” implies that net interest income increases when interest rates rise and decrease when interest rates decrease. “Liability sensitive” implies that net interest income decreases when interest rates rise and increase when interest rates decrease.“Neutral sensitivity” implies that net interest income does not change when interest rates change. The asset liability management policy limits aggregate market risk, as measured in this fashion, to an acceptable level within the context of risk-return trade-offs.

The simulation results noted above do not incorporate any management actions that might moderate the negative consequences of interest rate deviations. In addition, the simulation results noted above contain various assumptions such as a flat balance sheet, and the rate that deposit interest rates change instantaneously as general interest rates change. Therefore, they do not reflect likely actual results, but serve as estimates of interest rate risk. More specifically, the Company's pre-existing low cost of funds, and the presumption that depositors will not accept a negative rate environment, does not allow management the ability to meaningfully adjust the cost of deposits below zero. In addition, many of the Company's loans and investment securities are considered fixed rate interest earning assets. Therefore, in an instantaneous upward rate shock scenario, management would expect the cost of interest bearing liabilities to reprice faster than interest earning assets.

As with any method of measuring interest rate risk, certain shortcomings are inherent in the method of analysis presented in the preceding tables. For example, although certain of the Company’s assets and liabilities may have similar maturities or repricing time frames, they may react in different degrees to changes in market interest rates. In addition, the interest rates on certain of the Company’s asset and liability categories may precede, or lag behind, changes in market interest rates. Also, the actual rates of prepayments on loans and investments could vary significantly from the assumptions utilized in deriving the results as presented in the preceding tables. Further, a change in U.S. Treasury rates accompanied by a change in the shape of the treasury yield curve could result in different estimations from those presented herein. Accordingly, the results in the preceding tables should not be relied upon as indicative of actual results in the event of changing market interest rates. Additionally, the resulting estimates of changes in market value of equity are not intended to represent, and should not be construed to represent, estimates of changes in the underlying value of the Company.

Interest rate sensitivity is a function of the repricing characteristics of the Company’s portfolio of assets and liabilities. One aspect of these repricing characteristics is the time frame within which the interest-bearing assets and liabilities are subject to change in interest rates either at replacement, repricing or maturity. An analysis of the repricing time frames of interest-bearing assets and liabilities is sometimes called a “gap” analysis because it shows the gap between assets and liabilities repricing or maturing in each of a number of periods. Another aspect of these repricing characteristics is the relative magnitude of the repricing for each category of interest earning asset and interest-bearing liability given various changes in market interest rates. Gap analysis gives no indication of the relative magnitude of repricing given various changes in interest rates. Interest rate sensitivity management focuses on the maturity of assets and liabilities and their repricing during periods of changes in market interest rates. Interest rate sensitivity gaps are measured as the difference between the volumes of assets and liabilities in the Company’s current portfolio that are subject to repricing at various time horizons.

44 TriCo Bancshares 2022 10-K

The following interest rate sensitivity table shows the Company’s repricing gaps as of December 31, 2022. In this table transaction deposits, which may be repriced at will by the Company, have been included in the less than 3-month category. The inclusion of all of the transaction deposits in the less than 3-month repricing category causes the Company to appear liability sensitive. Because the Company may reprice its transaction deposits at will, transaction deposits may or may not reprice immediately with changes in interest rates.

Due to the limitations of gap analysis, as described above, the Company does not actively use gap analysis in managing interest rate risk. Instead, the Company relies on the more sophisticated interest rate risk simulation model described above as its primary tool in measuring and managing interest rate risk.

Liquidity

Liquidity refers to the Company’s ability to provide funds at an acceptable cost to meet loan demand and deposit withdrawals, as well as contingency plans to meet unanticipated funding needs or loss of funding sources. These objectives can be met from either the asset or liability side of the balance sheet. Asset liquidity sources consist of the repayments and maturities of loans, selling of loans, short-term money market investments, maturities of securities and sales of securities from the available-for-sale portfolio. These activities are generally summarized as investing activities in the Consolidated Statement of Cash Flows. Net cash used by investing activities, excluding cash acquired from VRB, totaled $1,149,582,000 in 2022. Net increases in loan balances from both originations and purchases used approximately $761,357,000 of cash, while purchases of investment securities, net of calls and maturities, used approximately $392,806,000 of cash.

Liquidity may also be impacted from liabilities through changes in deposits and borrowings outstanding. These activities are included under financing activities in the Consolidated Statement of Cash Flows. In 2022, financing activities used funds totaling $100,862,000, resulting from a decline of $253,625,000 in deposits, $35,797,000 in dividend payments, and an additional $27,148,000 used toward the repurchase of common stock, partially offset by an increase in cash from short term borrowings totaling $214,518,000. In addition, at December 31, 2022, the Company had loans and securities available to pledge towards future borrowings from the Federal Home Loan Bank and the Federal Reserve Bank of up to $2,485,905,000 and $299,689,000, respectively. As of December 31, 2022, the Company had $80,460,000 of other borrowings as described in Note 13 of the consolidated financial statements of the Company and the related notes at Item 8 of this report. While these sources are expected to continue to provide significant amounts of funds in the future, their mix, as well as the possible use of other sources, will depend on future economic and market conditions. Liquidity is also provided or used through the results of operating activities. In 2022, operating activities provided cash of $162,895,000 and primarily from net income of $125,419,000.

The Company’s investment securities, excluding held-to-maturity securities, plus cash and cash equivalents in excess of reserve requirements totaled $2,559,668,000 at December 31, 2022, which was 25.8% of total assets at that time. This was a decrease of $416,691,000 from $2,976,359,000 and 34.5% of total assets as of December 31, 2021.

Loan demand during 2023 will depend in part on economic and competitive conditions. The Company emphasizes the solicitation of non-interest bearing demand deposits and money market checking deposits, which are the least sensitive to interest rates. The outlook for deposit balances during 2023 is subject to actions from the Federal Reserve, heightened competition, the success of the Company’s sales

efforts, delivery of superior customer service and market conditions. In addition to the Federal Reserve's increase in interest rates, quantitative tightening through reduction of the Federal balance sheet is expected to place downward pressure on deposits balances during 2023. Depending on economic conditions, interest rate levels, and a variety of other conditions, proceeds from the sale or maturity of investment securities may be used to fund loans, or reduce short-term borrowings. However, due to concerns such as uncertainty in the general economic environment, competition and political uncertainty, loan demand and levels of customer deposits are not certain and forecasted changes in those balances are subject to significant volatility and uncertainty. At December 31, 2022, we believe the Company has sufficient liquidity and capital resources to meet its cash flow obligations over the next 12 months and for the foreseeable future.

The principal cash requirements of the Company are dividends on common stock when declared. The Company is dependent upon the payment of cash dividends by the Bank to service its commitments. Shareholder dividends are expected to continue subject to the Board’s discretion and 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 meet this payment schedule. Dividends from the Bank are subject to certain regulatory restrictions.

The maturity distribution of certificates of deposit in denominations of $100,000 or more is set forth in the following table. These deposits are generally more rate sensitive than other deposits and, therefore, are more likely to be withdrawn to obtain higher yields elsewhere if available.

Investment maturities

The maturity distribution and yields of the investment portfolio at December 31, 2022 is presented in the following tables. The timing of the maturities indicated in the tables below is based on final contractual maturities. Most mortgage-backed securities return principal throughout their contractual lives. As such, the weighted average life of mortgage-backed securities based on outstanding principal balance is usually significantly shorter than the final contractual maturity indicated below. Yields on tax exempt securities are shown on a tax equivalent basis.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Years Ended December 31, 2022, 2021 and 2020

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 and retail banking business in 32 California counties. 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 obtained through acquisition.

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. For financial reporting purposes, the Company’s investments in the Capital Trusts of $1,757,000 are accounted for under the equity method and, accordingly, are included in other assets on the consolidated balance sheets. The subordinated debentures issued and guaranteed by the Company and held by the Capital Trusts are reflected as debt on the Company’s consolidated balance sheets.

Use of Estimates in the Preparation of Financial Statements

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

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.

Business Combinations

The Company accounts for acquisitions of businesses using the acquisition method of accounting. Under the acquisition method, assets acquired and liabilities assumed are recorded at their estimated fair values at the date of acquisition. Management utilizes various valuation techniques including discounted cash flow analyses to determine these fair values. Any excess of the purchase price over amounts allocated to the acquired assets, including identifiable intangible assets, and liabilities assumed is recorded as goodwill.

Cash and Cash Equivalents

For purposes of the consolidated statements of cash flows, cash and cash equivalents include cash on hand, amounts due from banks, and federal funds sold. Net cash flows are reported for loan and deposit transactions and other borrowings.

Non-Marketable and Other Equity Securities

Non-marketable and other equity securities include qualified public welfare investments and venture capital/private equity funds. Our accounting for investments in non-marketable and other equity securities depends on several factors, including the level of ownership, power to control and the legal structure of the subsidiary making the investment. We base our accounting for such securities on: (i) fair value accounting, (ii) measurement alternative for other investments without a readily determinable fair value, and (iii) equity method accounting. During the twelve months ended December 31, 2022 and 2021, the Company recognized net unrealized gains of $35,000 and $718,000, respectively, in the consolidated statements of net income related to changes in the fair value of non-marketable and other equity securities.

54 TriCo Bancshares 2022 10-K

Debt Securities

The Company classifies its debt securities into one of three categories: trading, available for sale or held to maturity. Trading securities are bought and held principally for the purpose of selling in the near term and changes in the value of these securities are recorded through earnings. Held to maturity securities are those securities which the Company has the ability and intent to hold until maturity. These securities are carried at cost adjusted for amortization of premium and accretion of discount, computed by the effective interest method over their contractual lives. All other securities not included in trading or held to maturity are classified as available for sale. AFS securities are recorded at fair value. Unrealized gains and losses, net of the related tax effect, on available for sale securities are reported as a separate component of other accumulated comprehensive income in shareholders’ equity until realized. Discounts are amortized or accreted over the expected life of the related investment security as an adjustment to yield using the effective interest method. Premiums on callable debt securities are generally amortized to the earliest call date of the security with the exception of mortgage backed securities, where estimated prepayments, if any, are considered. Dividend and interest income are recognized when earned. Realized gains and losses are derived from the amortized cost of the security sold. The Company did not have any debt securities classified as trading during the three year period ended December 31, 2022.

The Company has made a policy election to exclude accrued interest from the amortized cost basis of debt securities and report accrued interest separately in the consolidated balance sheets. A debt security is placed on nonaccrual status at the time any principal or interest payments become more than 90 days delinquent or if full collection of interest or principal becomes uncertain. Accrued interest for a security placed on nonaccrual is reversed against interest income. There was no accrued interest related to debt securities reversed against interest income for the years ended December 31, 2022, 2021 and 2020.

The Company evaluates available for sale debt securities in an unrealized loss position to determine whether the decline in the fair value below the amortized cost basis (impairment) is due to credit-related factors or noncredit-related factors. Any impairment that is not credit related is recognized in other comprehensive income, net of applicable taxes. Credit-related impairment is recognized as an allowance for credit losses on the balance sheet, limited to the amount by which the amortized cost basis exceeds the fair value, with a corresponding adjustment to earnings. Both the allowance for credit losses and the adjustment to net income may be reversed if conditions change. However, if the Company intends to sell an impaired available for sale debt security or more likely than not will be required to sell such a security before recovering its amortized cost basis, the entire impairment amount is recognized in earnings with a corresponding adjustment to the security's amortized cost basis. In evaluating available for sale debt securities in unrealized loss positions for impairment and the criteria regarding its intent or requirement to sell such securities, the Company considers the extent to which fair value is less than amortized cost, whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred, and the results of reviews of the issuers' financial condition, among other factors. Changes in the allowance for credit losses are recorded as provision for (or reversal of) credit loss expense. Losses are charged against the ACL when management believes the uncollectability of an available for sale debt security is confirmed or when either of the criteria regarding intent or requirement to sell is met. No security credit losses were recognized during the years ended December 31, 2022, 2021 or 2020.

For HTM debt securities, the Company measures expected credit losses on held-to-maturity debt securities on a collective basis by major security type, then further disaggregated by sector and bond rating. Accrued interest receivable on held-to-maturity (HTM) debt securities is excluded from the estimate of credit losses. The estimate of expected credit losses considers historical credit loss information that is adjusted for current condition and reasonable and supportable forecasts based on current and expected changes in credit ratings and default rates. Based on the implied guarantees of the U. S. Government or its agencies related to certain of these HTM investment securities, and the absence of any historical or expected losses, substantially all qualify for a zero loss assumption. Management has separately evaluated its HTM investment securities from obligations of state and political subdivisions utilizing the historical loss data represented by similar securities over a period of time spanning nearly 50 years. As a result of this evaluation, management determined that the expected credit losses associated with these securities is not significant for financial reporting purposes and therefore, no allowance for credit losses has been recognized during the years ended December 31, 2022, 2021 or 2020.

Restricted Equity Securities

Restricted equity securities represent the Company’s investment in the stock of the Federal Home Loan Bank of San Francisco (“FHLB”) and are carried at par value, which reasonably approximates its fair value. While technically these are considered equity securities, there is no market for the FHLB stock. Therefore, the shares are considered as restricted investment securities. Management periodically evaluates FHLB stock for other-than-temporary impairment. Management’s determination of whether these investments are impaired is based on its assessment of the ultimate recoverability of cost rather than by recognizing temporary declines in value. The determination of whether a decline affects the ultimate recoverability of cost is influenced by criteria such as (1) the significance of any decline in net assets of the FHLB as compared to the capital stock amount for the FHLB and the length of time this situation has persisted, (2) commitments by the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLB, (3) the impact of legislative and regulatory changes on institutions and, accordingly, the customer base of the FHLB, and (4) the liquidity position of the FHLB.

As a member of the FHLB system, the Bank is required to maintain a minimum level of investment in FHLB stock based on specific percentages of its outstanding mortgages, total assets, or FHLB advances. The Bank may request redemption at par value of any stock in excess of the minimum required investment. Stock redemptions are at the discretion of the FHLB. Both cash and stock dividends are reported as income when received.

Loans Held for Sale

Loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or fair value, as determined by aggregate outstanding commitments from investors of current investor yield requirements. Net unrealized losses are recognized through a valuation allowance by charges to non-interest income.

Mortgage loans held for sale are generally sold with the mortgage servicing rights retained by the Company. Gains or losses on the sale of loans that are held for sale are recognized at the time of the sale and determined by the difference between net sale proceeds and the net book value of the loans less the estimated fair value of any retained mortgage servicing rights.

Loans

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

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

Allowance for Credit Losses - Loans

The Company measures credit losses under ASU 2016-03 Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which replaced the incurred loss methodology, and is referred to as the current expected credit loss (CECL) methodology. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized costs, including loan receivables and held-to-maturity debt securities.

The allowance for credit losses (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 and U.S. gross domestic product.

A loan is considered to be collateral dependent when repayment is expected to be provided substantially through the operation or sale of the collateral. The ACL on collateral dependent loans is measured using the fair value of the underlying collateral, adjusted for costs to sell when applicable, less the amortized cost basis of the financial asset. If the value of underlying collateral is determined to be less than the recorded amount of the loan, a charge-off will be taken. Loans for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulties, is considered to be a troubled debt restructuring (TDR). The ACL on a TDR is measured using the same method as all other portfolio loans, except when the value of a concession cannot be measured using a method other than the discounted cash flow method. When the value of a concession is measured using the discounted cash flow method, the ACL is determined by discounting the expected future cash flows at the original interest rate of the loan.

PCD assets are assets acquired at a discount that is due, in part, to credit quality deterioration since origination which may be determined through observation of missed payments, downgrade in risk rating, deterioration of a borrower's financial trends or other observable factors including subjectivity utilized by management. PCD assets 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 consolidated balance sheets, while the allowance for acquired non-PCD assets, such as loans, is recorded through the provision for credit losses on the consolidated statements of income, 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 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 these 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.

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.

Real Estate Owned

Real estate owned (REO) includes assets acquired through, or in lieu of, loan foreclosure. REO is held for sale and are initially recorded at fair value less estimated costs to sell at the date of acquisition, establishing a new cost basis. Physical possession of residential real estate property collateralizing a consumer mortgage loan occurs when legal title is obtained upon completion of foreclosure or when the borrower conveys all interest in the property to satisfy the loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Any write-downs based on the asset’s fair value less costs to sell at the date of acquisition are charged to the allowance for loan and lease losses. Any recoveries based on the asset’s fair value less estimated costs to sell in excess of the recorded value of the loan at the date of acquisition are recorded to the allowance for loan and lease losses. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. If fair value declines subsequent to foreclosure, a valuation allowance is recorded through expense. Operating costs after acquisition are expensed. Revenue and expenses from operations and changes in the valuation allowance are included in other non-interest expense, along with the gain or loss on sale of REO.

Premises and Equipment

Land is carried at cost. Land improvements, buildings and equipment, including those acquired under capital lease, are stated at cost less accumulated depreciation and amortization. Depreciation and amortization expenses are computed using the straight-line method over the shorter of the estimated useful lives of the related assets or lease terms. Asset lives range from 3-10 years for furniture and equipment and 15-40 years for land improvements and buildings.

Company Owned Life Insurance

The Company has purchased life insurance policies on certain key executives. Company owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.

As a result of current tax law and the nature of these policies, the Bank records any increase in cash value of these policies as nontaxable non-interest income. If the Bank decided to surrender any of the policies prior to the death of the insured, such surrender may result in a tax expense related to the life-to-date cumulative increase in cash value of the policy. If the Bank retains such policies until the death of the insured, the Bank would receive nontaxable proceeds from the insurance company equal to the death benefit of the policies. The Bank has

58 TriCo Bancshares 2022 10-K

entered into Joint Beneficiary Agreements (JBAs) with certain of the insured that provide some level of sharing of the death benefit, less the cash surrender value, among the Bank and the beneficiaries of the insured upon the receipt of death benefits.

Goodwill, Other Intangible and Long-Lived Assets

Goodwill represents the excess of costs over fair value of net assets of businesses acquired from a business combination. The Company has an identifiable intangible asset consisting of core deposit intangibles (“CDI”). CDI are amortized over their respective estimated useful lives and reviewed periodically for impairment. Goodwill and other intangible assets acquired in a business combination and determined to have an indefinite useful life are not amortized, but instead tested for impairment at least annually. Other intangible assets with estimable useful lives are amortized over their respective estimated useful lives to their estimated residual values, and reviewed periodically for impairment.

As of September 30 of each year, goodwill is tested for impairment, and is tested for impairment more frequently if events and circumstances indicate that the asset might be impaired. An impairment loss is recognized to the extent that the carrying amount exceeds the asset’s fair value.

Long-lived assets, such as premises and equipment, and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of would be separately presented in the balance sheet and reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated. The assets and liabilities of a disposed group classified as held for sale would be presented separately in the appropriate asset and liability sections of the consolidated balance sheet.

Mortgage Servicing Rights

Mortgage servicing rights (“MSR”) represent the Company’s right to a future stream of cash flows based upon the contractual servicing fee associated with servicing mortgage loans. Our MSR arise from residential and commercial mortgage loans that we originate and sell, but retain the right to service the loans. The net gain from the retention of the servicing right is included in gain on sale of loans in non-interest income when the loan is sold. Fair value is based on market prices for comparable mortgage servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, the custodial earnings rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses. Servicing fees, when earned, and changes in fair value of the MSR, are recorded in non-interest income.

The Company accounts for MSR at fair value. The determination of fair value of our MSR requires management judgment because they are not actively traded. The determination of fair value for MSR requires valuation processes which combine the use of discounted cash flow models and extensive analysis of current market data to arrive at an estimate of fair value. The cash flow and prepayment assumptions used in our discounted cash flow model are based on empirical data drawn from the historical performance of our MSR, which we believe are consistent with assumptions used by market participants valuing similar MSR, and from data obtained on the performance of similar MSR. The key assumptions used in the valuation of MSR include mortgage prepayment speeds and the discount rate. These variables can, and generally will, change from quarter to quarter as market conditions and projected interest rates change. The key risks inherent with MSR are prepayment speed and changes in interest rates.

Leases

The Company records a right-of-use asset (“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 is also required to record a lease liability on the consolidated balance sheets for the present value of future payment commitments. Substantially 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 twelve months or less) within the ROUA and lease liability. Known or determinable adjustments to the required minimum future lease payments are 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 are not unknown and not determinable at lease commencement and therefore, are 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. The Company uses 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.

Off-Balance Sheet Credit Related Financial Instruments

In the ordinary course of business, the Company has entered into commitments to extend credit, including commitments under credit card arrangements, commercial letters of credit, and standby letters of credit. Such financial instruments are recorded when they are funded.

Low Income Housing Tax Credits

The Company accounts for low income housing tax credits and the related qualified affordable housing projects using the proportional amortization method. Under the proportional amortization method, the Company amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). Upon entering into a qualified affordable housing project, the Company records, in other liabilities, the entire amount that it has agreed to invest in the project, and an equal amount, in other assets, representing its investment in the project. As the Company disburses cash to satisfy its investment obligation, other liabilities are reduced. Over time, as the tax credits and other tax benefits of the project are realized by the Company, the investment recorded in other assets is reduced using the proportional amortization method.

Income Taxes

The Company’s accounting for income taxes is based on an asset and liability approach. The Company recognizes the amount of taxes payable or refundable for the current year, and deferred tax assets and liabilities for the future tax consequences that have been recognized in its financial statements or tax returns. The measurement of tax assets and liabilities is based on the provisions of enacted tax laws. A valuation allowance, if needed, reduces deferred tax assets to the expected amount most likely to be realized. Realization of deferred tax assets is dependent upon the generation of a sufficient level of future taxable income and recoverable taxes paid in prior years. Although realization is not assured, management believes it is more likely than not that all of the deferred tax assets will be realized.

A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. Interest and/or penalties related to income taxes are reported as a component of non-interest income.

Share-Based Compensation

Compensation cost is recognized for stock options and restricted stock awards issued to employees and directors, based on the fair value of the awards at the date of grant. The estimate of the fair value of stock options and performance based restricted awards are based on a Black-Scholes or Monte Carlo model, respectively, while the market price of the common stock at the date of grant is used for time based restricted awards. Compensation cost is recognized over the required service period, generally defined as the vesting or measurement period. The Company’s accounting policy is to recognize forfeitures as they occur.

Earnings per Share

Basic earnings per share represents income available to common shareholders divided by the weighted-average number of common shares outstanding during the period. There are no unvested share-based payment awards that contain rights to nonforfeitable dividends (participating securities). Diluted earnings per share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustments to income that would result from assumed issuance. Potential common shares that may be issued by the Company relate solely from outstanding stock options and restricted stock units, and are determined using the treasury stock method.

Revenue Recognition

The Company records revenue from contracts with customers in accordance with Accounting Standards Codification Topic 606, “Revenue from Contracts with Customers” (“Topic 606”). Under Topic 606, the Company must identify the contract with a customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract, and recognize revenue when (or as) the Company satisfies a performance obligation.

Most of our revenue-generating transactions are not subject to Topic 606, including revenue generated from financial instruments, such as our loans and investment securities. In addition, certain non-interest income streams such as fees associated with mortgage servicing rights, financial guarantees, derivatives, and certain credit card fees are also not in scope of the new guidance. The Company’s non-interest revenue streams are largely based on transactional activity, or standard month-end revenue accruals such as asset management fees based on month-end market values. Consideration is often received immediately or shortly after the Company satisfies its performance obligation and revenue is recognized. The Company does not typically enter into long-term revenue contracts with customers, and therefore, does not experience significant contract balances. As of December 31, 2022 and December 31, 2021, the Company did not have any significant contract balances. The Company has evaluated the nature of its revenue streams and determined that further disaggregation of revenue into more granular categories beyond what is presented in Note 18 was not necessary. The following are descriptions of revenues within the scope of ASC 606.

Deposit service charges

The Company earns fees from its deposit customers for account maintenance, transaction-based and overdraft services. Account maintenance fees consist primarily of account fees and analyzed account fees charged on deposit accounts on a monthly basis. The performance obligation is satisfied and the fees are recognized on a monthly basis as the service period is completed. Transaction-based fees on deposit accounts are charged to deposit customers for specific services provided to the customer, such as non-sufficient funds fees, overdraft fees, and wire fees. The performance obligation is completed as the transaction occurs and the fees are recognized at the time each specific service is provided to the customer.

Debit and ATM interchange fees

Debit and ATM interchange income represent fees earned when a debit card issued by the Company is used. The Company earns interchange fees from debit cardholder transactions through the Visa payment network. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder. The performance obligation is satisfied and the fees are earned when the cost of the transaction is charged to the cardholders’ debit card. Certain expenses directly associated with the credit and debit card are recorded on a net basis with the interchange income.

Commission on sale of non-deposit investment products

Commissions on sale of non-deposit investment products consist of fees earned from advisory asset management, trade execution and administrative fees from investments. Advisory asset management fees are variable, since they are based on the underlying portfolio value, which is subject to market conditions and asset flows. Advisory asset management fees are recognized quarterly and are based on the portfolio values at the end of each quarter. Brokerage accounts are charged commissions at the time of a transaction and the commission schedule is based upon the type of security and quantity. In addition, revenues are earned from selling insurance and annuity policies. The amount of revenue earned is determined by the value and type of each instrument sold and is recognized at the time the policy or contract is written.

Merchant fee income

Merchant fee income represents fees earned by the Company for card payment services provided to its merchant customers. The Company outsources these services to a third party to provide card payment services to these merchants. The third party provider passes the payments made by the merchants through to the Company. The Company, in turn, pays the third party provider for the services it provides to the merchants. These payments to the third party provider are recorded as expenses as a net reduction against fee income. In addition, a portion of the payment received represents interchange fees which are passed through to the card issuing bank. Income is primarily earned based on the dollar volume and number of transactions processed. The performance obligation is satisfied and the related fee is earned when each payment is accepted by the processing network.

Gain/loss on other real estate owned, net

The Company records a gain or loss from the sale of other real estate owned when control of the property transfers to the buyer, which generally occurs at the time of an executed deed of trust. When the Company finances the sale of other real estate owned to the buyer, the Company assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the other real estate owned asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on sale, the Company adjusts the transaction price and related gain or loss on sale if a significant financing component is present. Gains or losses from transactions associated with other real estate owned are recorded as a component of non-interest expense.

Reclassifications

Certain amounts reported in previous consolidated financial statements have been reclassified and recalculated to conform to the presentation in this report. These reclassifications did not affect previously reported amounts of net income, total assets or total shareholders’ equity.

Accounting Standards Adopted in 2022

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This ASU provides temporary optional guidance to ease the potential burden in accounting for reference rate reform by providing optional expedients and exceptions for applying generally accepted accounting principles (GAAP) to contracts, hedging relationships, and other transactions affected if certain criteria are met. At the time that Update 2020-04 was issued, the UK Financial

Conduct Authority (FCA) had established its intent that it would no longer be necessary to persuade, or compel, banks to submit to LIBOR after December 31, 2021. As a result, the sunset provision was set for December 31, 2022—12 months after the expected cessation date of all currencies and tenors of LIBOR. In March 2021, the FCA announced that the intended cessation date of the overnight 1-, 3-, 6-, and 12-month tenors of USD LIBOR would be June 30, 2023, which is beyond the current sunset date of Topic 848. Because the current relief in Topic 848 may not cover a period of time during which a significant number of modifications may take place, the amendments in this

Update defer the sunset date of Topic 848 from December 31, 2022, to December 31, 2024. As the Company has an insignificant number of instruments that are applicable to this ASU, management has determined that no impact to the valuations of these instruments are applicable for financial reporting purposes.

Accounting Standards Pending Adoption

In March 2022, the FASB issued ASU 2022-02, Financial Instruments — Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. The amendments in this Update eliminate the TDR recognition and measurement guidance and, instead, require that an entity evaluate (consistent with the accounting for other loan modifications) whether the modification represents a new loan or a continuation of an existing loan. The amendments enhance existing disclosure requirements and introduce new requirements related to certain modifications of receivables made to borrowers experiencing financial difficulty. Furthermore, the amendments in this Update require that an entity disclose current-period gross write-offs by year of origination for financing receivables and net investment in leases within the scope of Subtopic 326-20. The Company adopted these amendments on January 1, 2023 and has thus far observed no material impact to

deferred fees and costs and the related timing of net interest income recognition as a result of adoption.

Note 2 - Business Combinations

On March 25, 2022, the Company completed its acquisition of Valley Republic Bancorp (VRB), including the merger of Valley Republic Bank into Tri Counties Bank, with Tri Counties Bank as the surviving entity, in accordance with the terms of the merger agreement dated as of July 27, 2021. The cash and stock transaction was valued at $174,016,000 in aggregate, based on TriCo's closing stock price of $42.48 on March 25, 2022. Under the terms of the merger agreement, the Company issued 4,105,518 shares, in addition to approximately $431,000 in cash paid out for settlement of stock option awards at VRB.

The acquisition of VRB has been accounted for as a business combination. The Company recorded the fair values based on the valuations available as of acquisition date, and subject to adjustment up to one year following the merger date of March 25, 2022. During the fourth quarter of 2022, an adjustment to the initial allocation was based on more detailed information obtain about tax-related matters. Management believes the purchase price allocation is now finalized as December 31, 2022.

The following table summarizes the consideration paid for VRB and the amounts of assets acquired and liabilities assumed that were recorded at the acquisition date (in thousands):

There were no sales of debt securities during the years ended December 31, 2022 and 2021, respectively. During 2020, proceeds from sales of debt securities totaled $229,000, resulting in gross gains of $7,000. Investment securities with an aggregate carrying value of $595,779,000 and $423,892,000 at December 31, 2022 and 2021, respectively, were pledged as collateral for specific borrowings, lines of credit and local agency deposits.

The amortized cost and estimated fair value of debt securities at December 31, 2022 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 December 31, 2022, obligations of U.S. government and agencies with an amortized cost basis totaling $1,533,255,000 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 December 31, 2022, the Company estimates the average remaining life of these mortgage-backed securities issued by U.S. government corporations and agencies to be approximately 6.4 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: Unrealized losses on investments in obligations of U.S. government corporations and agencies are caused by interest rate increases. 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 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, these investments are not considered other-than-temporarily impaired. At December 31, 2022, 172 debt securities representing obligations of U.S. government corporations and agencies had unrealized losses with aggregate depreciation of 12.48% from the Company’s amortized cost basis.

Obligations of states and political subdivisions: The unrealized losses on investments in obligations of states and political subdivisions were caused by increases in required yields by investors in these types of securities. It is expected that the securities would not be settled at a price less than the amortized cost of the investment. Because 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, these investments are not considered other-than-temporarily impaired. At December 31, 2022, 202 debt security representing obligations of states and political subdivisions had unrealized losses with aggregate depreciation of 13.16% from the Company’s amortized cost basis.

Corporate bonds: The unrealized losses on investments in corporate bonds were caused by increases in required yields by investors in these types of securities. 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 and there has been no allowance for credit losses as of and for the year ended December 31, 2022. At December 31, 2022, 6 asset backed securities had unrealized losses with aggregate depreciation of 6.70% from the Company’s amortized cost basis.

Asset backed securities: The unrealized losses on investments in asset backed securities were caused by increases in required yields by investors in these types of securities. At the time of purchase, each of these securities were rated AA or AAA and through December 31, 2022 have not experienced any deterioration in credit rating. The Company continues to monitor these securities for changes in credit rating or other indications of credit deterioration. 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, these investments are not considered other-than-temporarily impaired. At December 31, 2022, 48 asset backed securities had unrealized losses with aggregate depreciation of 3.36% from the Company’s amortized cost basis.

Non-agency collateralized mortgage obligations: The unrealized losses on investments in asset backed securities were caused by increases in required yields by investors in these types of securities. 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 and there has been no allowance for credit losses as of and for the year ended December 31, 2022. At December 31, 2022, 22 asset backed securities had unrealized losses with aggregate depreciation of 10.88% from the Company’s amortized cost basis.

Marketable equity securities: As there were no sales of marketable equity securities, all unrealized gains or losses recognized during the reporting period were for equity securities still held as of the end of the reporting period.

The Company monitors credit quality of debt securities held-to-maturity through the use of credit rating. The Company monitors the credit rating on a monthly basis.

In March 2020, the Small Business Administration ("SBA") Paycheck Protection Program ("PPP") was created to help small businesses keep workers employed during the COVID-19 crisis. As of December 31, 2022 and 2021, the total gross balance outstanding of PPP loans, which are included in commercial and industrial loans above, was $1,617,000 and $63,311,000, respectively, as compared to total PPP originations of $640,410,000. As of December 31, 2022, there was approximately $15,000 in net deferred fee income remaining to be recognized. During the year ended December 31, 2022, the Company recognized $2,149,000 in fees on PPP loans, as compared with $14,148,000 and $7,760,000 for the years ended December 31, 2021 and 2020, respectively. The SBA ended PPP and did not accept new borrowing applications, effective May 31, 2021.

Note 5 – Allowance for Credit Losses

The ACL was $105,680,000 as of December 31, 2022 as compared to $85,376,000 at December 31, 2021. The provision for credit losses on loans of $17,945,000 during the year ended December 31, 2022 was comprised of $10,820,000 in day 1 required reserves from loans acquired in connection with the VRB merger in the first quarter of 2022. Additionally, the Company designated certain loans and leases purchased from VRB as PCD, which required $2,037,000 in additional credit reserves as of the acquisition date. For PCD loans and leases, the initial estimate of expected credit losses is recognized in the ACL on the date of acquisition using the same methodology as other loans and leases held-for-investment.

The remaining increase in the allowance for credit reserves was the result of changes in loan volume and changes in credit quality associated with levels of classified, past due and non-performing loans in addition to changes in qualitative factors. The quantitative component of the ACL increased reserve requirements due to loan volume growth and increases in specific reserves. In addition to the quantitative loan portfolio, credit quality characteristics which are illustrated in the following tabular disclosures, the Company’s expected credit loss methodology (CECL) incorporates the use of qualitative factors. The qualitative components of the ACL resulted in a net increase in required reserves despite continued improvement in US employment rates, due to increased uncertainty in the global economic markets, US economic policy uncertainty, and the continued rise in corporate debt yields. As compared to historical norms, inflation remains elevated from continued disruptions in the supply chain, wage pressures, and higher living costs such as housing and food prices. Management notes the rapid intervals of rate increases by the Federal Reserve and inversion of the yield curve, have boosted expectations of the US entering a recession within 12 months. As a result, management continues to believe that certain credit weakness are likely present in the overall economy and that it is appropriate to maintain an allowance for credit losses that incorporates such risk factors.

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 $1,000,000 and non-homogeneous loans, such as commercial real estate loans, unless other indicators, such as delinquency, trigger more frequent evaluation. Loans below the $1,000,000 threshold and homogenous in nature are evaluated as needed for proper grading based on delinquency and borrower credit scores.

Collateral values may be determined by appraisals obtained through Bank approved, licensed appraisers, qualified independent third parties, public value information (blue book values for autos), sales invoices, or other appropriate means. Appropriate valuations are obtained at initiation of the credit and periodically (every 3-12 months depending on collateral type) once repayment is questionable and the loan has been classified.

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.

Once a loan becomes delinquent and repayment becomes questionable, a Bank collection officer will address collateral shortfalls with the borrower and attempt to obtain additional collateral. If this is not forthcoming and payment in full is unlikely, the Bank will estimate its probable loss, using a recent valuation as appropriate to the underlying collateral less estimated costs of sale, and charge the loan down to the estimated net realizable amount. Depending on the length of time until ultimate collection, the Bank may revalue the underlying collateral and take additional charge-offs as warranted. Revaluations may occur as often as every 3-12 months depending on the underlying collateral and volatility of values. Final charge-offs or recoveries are taken when collateral is liquidated and actual loss is known. Unpaid balances on loans after or during collection and liquidation may also be pursued through lawsuit and attachment of wages or judgment liens on borrower’s other assets.

For all new TDRs, an impairment analysis is conducted. If the loan is determined to be collateral dependent, any additional amount of impairment will be calculated based on the difference between estimated collectible value and the current carrying balance of the loan. This difference could result in an increased provision and is typically charged off. If the asset is determined not to be collateral dependent, the impairment is measured on the net present value difference between the expected cash flows of the restructured loan and the cash flows which would have been received under the original terms. The effect of this could result in a requirement for additional provision to the reserve. The effect of these required provisions for the period are indicated above.

Typically if a TDR defaults during the period, the loan is then considered collateral dependent and, if it was not already considered collateral dependent, an appropriate provision will be reserved or charge will be taken. The additional provisions required resulting from default of previously modified TDR’s are noted above.

Goodwill	$	304,442	$	83,570	$	—	$	220,872

Impairment exists when a Company’s carrying value exceeds its fair value. Goodwill is evaluated for impairment annually. At September 30, 2022, the Company had positive equity and the Company elected to perform a qualitative assessment to determine if it was more likely than not that the fair value of the Company exceeded its carrying value, including goodwill. The qualitative assessment indicated that it was more likely than not that the fair value of the reporting unit exceeds its carrying value, resulting in no impairment. For each of the years in the three year period ended December 31, 2022, there were no impairment charges recognized.

Other collateralized borrowings are generally overnight maturity borrowings from non-financial institutions that are collateralized by securities owned by the Company. As of December 31, 2022, the Company has pledged as collateral and sold under agreements to repurchase investment securities with fair value of $47,905,000 under these other collateralized borrowings.

The Company maintains a collateralized line of credit with the FHLB. Based on the FHLB stock requirements at December 31, 2022, this line provided for maximum borrowings of $2,485,905,000 of which $216,700,000 was outstanding. As of December 31, 2022, the Company had designated investment securities with a fair value of $80,187,000 and loans with unpaid principal balances totaling $4,389,161,000 as potential collateral under this collateralized line of credit with the FHLB.

The Company maintains a collateralized line of credit with the Federal Reserve Bank of San Francisco (“FRB”). As of December 31, 2022, this line provided for maximum borrowings of $299,689,000 of which none was outstanding. As of December 31, 2022, the Company has designated investment securities with fair value of $5,000 and loans with unpaid principal balances totaling $424,946,000 as potential collateral under this collateralized line of credit with the FRB.

The Company has available unused correspondent banking lines of credit from commercial banks totaling $30,000,000 for federal funds transactions at December 31, 2022.

Note 14 – Junior Subordinated Debt

At December 31, 2022, the Company had five wholly-owned subsidiary business trusts that had issued $63.0 million of trust preferred securities (the “Capital Trusts”). Trust preferred securities accrue and pay distributions periodically at specified annual rates as provided in the indentures. The trusts used the net proceeds from the offering to purchase a like amount of subordinated debentures (the “Debentures”) of the Company. The Debentures are the sole assets of the trusts. The Company’s obligations under the subordinated debentures and related documents, taken together, constitute a full and unconditional guarantee by the Company of the obligations of the trusts. The trust preferred securities are mandatorily redeemable upon the maturity of the Debentures, or upon earlier redemption as provided in the indentures. The Company has the right to redeem the Debentures in whole (but not in part) on or after specific dates, at a redemption price specified in the indentures plus any accrued but unpaid interest to the redemption date. The Company also has a right to defer consecutive payments of interest on the debentures for up to five years.

The Company organized two of the Capital Trusts. The Company acquired its three other Capital Trusts and assumed their related Debentures as a result of its acquisition of North Valley Bancorp in 2014. The acquired Debentures were recorded on the Company’s books at their fair values on the acquisition date. The related fair value discounts to face value of these Debentures will be amortized over the remaining period in which their values are fully allowed to be included in the Company's capital ratio calculations using the effective interest method.

The recorded book values of the Debentures issued by the Capital Trusts are reflected as junior subordinated debt in the Company’s consolidated balance sheets. The common stock issued by the Capital Trusts and owned by the Company is recorded in other assets in the

82 TriCo Bancshares 2022 10-K

Company’s consolidated balance sheets. The recorded book value of the debentures issued by the Capital Trusts, less the recorded book value of the common stock of the Capital Trusts owned by the Company will continue to qualify as Tier 1 or Tier 2 capital under interim guidance issued by the Board of Governors of the Federal Reserve System until only five years remain until their scheduled maturity.

In connection with the acquisition of Valley Republic Bancorp the Company assumed $36.0 million in subordinated capital notes, comprised of $16.0 million that matures in 2029 and $20.0 million that matures in 2035. The notes that mature in 2029 provide for quarterly interest payments at a fixed rate of 6.00% until March 29, 2024 and then will have a floating rate of three month LIBOR plus 3.52% until maturity. The notes that mature in 2035 provide for quarterly interest payments at a fixed rate of 5.00% until August 27, 2025 and then will have a floating rate of 90-day average SOFR plus 4.90% until maturity. The acquired subordinated capital notes were recorded on the Company’s books at their fair values on the acquisition date. The related fair value premiums to face value will be amortized over the remaining maturity period using the effective interest method. The Company expects a comparable SOFR rate term to replace LIBOR as the benchmark rate index for applicable debentures in 2024.

The following table summarizes the terms and recorded balance of each subordinated debenture as of the date indicated (dollars in thousands):

Note 15 – Commitments and Contingencies

Restricted Cash Balances — Reserves (in the form of deposits with the San Francisco Federal Reserve Bank) were not required to be maintained as of December 31, 2022 and 2021.

Financial Instruments with Off-Balance-Sheet Risk — The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, standby letters of credit, and deposit account overdraft privilege. Those instruments involve, to varying degrees, elements of risk in excess of the amount recognized in the balance sheet. The contract amounts of those instruments reflect the extent of involvement the Company has in particular classes of financial instruments.

The Company’s exposure to loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit written is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. The Company’s exposure to loss in the event of nonperformance by the other party to the financial instrument for deposit account overdraft privilege is represented by the overdraft privilege amount disclosed to the deposit account holder.

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

	December 31,
(in thousands)	2022		2021
Financial instruments whose amounts represent risk:
Commitments to extend credit:
Commercial loans	$	656,705	$	409,950

Real estate mortgage loans	458,896		333,764
Real estate construction loans	312,371		213,563
Standby letters of credit	26,599		21,871
Deposit account overdraft privilege	126,634		125,670

83 TriCo Bancshares 2022 10-K

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates of one year or less or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on Management’s credit evaluation of the customer. Collateral held varies, but may include accounts receivable, inventory, property, plant and equipment, residential properties, and income-producing commercial properties.

Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support private borrowing arrangements. Most standby letters of credit are issued for one year or less. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. Collateral requirements vary, but in general follow the requirements for other loan facilities.

Deposit account overdraft privilege amount represents the unused overdraft privilege balance available to the Company’s deposit account holders who have deposit accounts covered by an overdraft privilege. The Company has established an overdraft privilege for certain of its deposit account products whereby all holders of such accounts who bring their accounts to a positive balance at least once every thirty days receive the overdraft privilege. The overdraft privilege allows depositors to overdraft their deposit account up to a predetermined level. The predetermined overdraft limit is set by the Company based on account type.

Legal Proceedings — Neither the Company nor its subsidiaries are a party to any other pending legal proceedings that are material, nor is their property the subject of any other material pending legal proceeding at this time. All other legal proceedings are routine and arise out of the ordinary course of the Bank’s business. None of those proceedings are currently expected to have a material adverse impact upon the Company’s and the Bank’s business, their consolidated financial position nor their operations in any material amount not already accrued, after taking into consideration any applicable insurance.

Other Commitments and Contingencies—The Company has entered into employment agreements or change of control agreements with certain officers of the Company providing severance payments and accelerated vesting of benefits under supplemental retirement agreements to the officers in the event of a change in control of the Company and termination for other than cause or after a substantial and material change in the officer’s title, compensation or responsibilities.

The Bank owns 13,396 shares of Class B common stock of Visa Inc. which are convertible into Class A common stock at a conversion ratio of 1.5991 per Class B share. As of December 31, 2022, the value of the Class A shares was $207.76 per share. Utilizing the conversion ratio, the value of unredeemed Class A equivalent shares owned by the Bank was $4,451,000 as of December 31, 2022, and has not been reflected in the accompanying consolidated financial statements. The shares of Visa Class B 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 conversion ratio will be increased to reflect that surplus.

Mortgage loans sold to investors may be sold with servicing rights retained, with only the standard legal representations and warranties regarding recourse to the Bank. Management believes that any liabilities that may result from such recourse provisions are not significant.

Note 16 – Shareholders’ Equity

Dividends Paid

The Bank paid to the Company cash dividends in the aggregate amounts of $64,188,000, $31,571,000, and $63,419,000 in 2022, 2021, and 2020, respectively. The Bank is regulated by the Federal Deposit Insurance Corporation (“FDIC”) and the State of California Department of Financial Protection & Innovation (the “DFPI”). Absent approval from the Commissioner of the DPFI, 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. Under this law, at December 31, 2022, the Bank could have paid dividends of $157,036,000 to the Company without the approval of the Commissioner of the DFPI.

Stock Repurchase Plan

On February 25, 2021 the Board of Directors approved the authorization to repurchase 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 program is subject to change. The 2021 Repurchase Plan has no expiration date (in accordance with applicable laws and regulations) and as of and for year ended December 31, 2022, the Company repurchased 576,881 shares. The Company repurchased 63,317 shares during the year ended December 31, 2021.

In connection with approval of the 2021 Repurchase Plan, the Company’s previous repurchase program adopted on November 12, 2019 (the 2019 Repurchase Plan) was terminated. Under the 2019 Repurchase Plan, during the years ended December 31, 2021 and 2020 the Company had repurchased 223 and 858,717 shares, 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 withholding taxes on such shares. During the years ended December 31, 2022, 2021, and 2020, employees tendered 39,447, 28,276, and 12,488 shares, respectively, of the Company's common stock in connection with option exercises. Employees also tendered 27,840, 19,413 and 12,058 shares in connection with other share based awards during December 31, 2022, 2021 and 2020, respectively. In total, shares of the Company's common stock tendered had market values of $1,269,000, $2,118,000, and $736,000 for the years ended December 31, 2022, 2021 and 2020, respectively. 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 or 2019 Repurchase Plans.

Note 17 – Stock Options and Other Equity-Based Incentive Instruments

In April 2019, the Company’s Board of Directors adopted the TriCo Bancshares 2019 Equity Incentive Plan (2019 Plan) covering officers, employees, directors of, and consultants to, the Company. The 2019 Plan was approved by the Company’s shareholders in May 2019. The 2019 Plan allows the Company to issue equity-based incentives representing up to 1,500,000 shares, such as incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock, restricted stock units and performance awards (which could either be restricted stock or restricted stock units) (collectively, Awards). The 2019 Plan contains several enhanced corporate governance provisions, including: expressly providing that executives’ Awards and cash incentive compensation are subject to TriCo’s potential clawback or recoupment if the Company must restate its financial statements; generally imposing a one year minimum vesting period on Awards; generally requiring participants to hold at least 50% of the shares acquired under an Award for at least one year; and clarifying that credit for dividends declared on shares of common stock underlying an Award is subject to the same vesting requirements as the common stock underlying the Award.

The number of shares available for issuance under the 2019 Plan will be reduced by: (i) one share for each share of common stock issued pursuant to a stock option; (ii) the total number of stock appreciation rights that are exercised, including any shares of common stock underlying such Awards that are not actually issued to the participant as the result of a net settlement; (iii) two shares for each share of common stock issued pursuant to a performance award, a restricted share Award or an RSU Award and (iv) any shares of common stock used to pay any exercise price or tax withholding obligation with respect to any Award. When Awards made under the 2019 Plan expire or are forfeited or cancelled, the underlying shares will become available for future Awards under the 2019 Plan. To the extent that a share of common stock pursuant to an Award that counted as two shares again becomes available for issuance under the 2019 Plan, the number of shares of common stock available for issuance under the 2019 Plan will increase by two shares. If shares of common stock issued pursuant to the Plan are repurchased by, or are surrendered or forfeited to the Company at no more than cost, then such shares will again be available for the grant of Awards under the Plan. Any shares of common stock repurchased by the Company with cash proceeds from the exercise of options will not, however, be added back to the pool of share available for issuance under the 2019 Plan. Shares awarded and delivered under the 2019 Plan may be authorized but unissued shares or reacquired shares. Shares tendered to TriCo or withheld from delivery to a participant as payment of the exercise price or in connection with the “net exercise” of a stock option or to satisfy TriCo’s tax withholding obligations will not again become available for future Awards under the 2019 Plan. As of December 31, 2022, there were no outstanding options for the purchase of common shares and 139,194 RSUs were outstanding. The number of shares that remain available for issuance is not more than 763,495, which could decrease based on the level of the Company's future performance and outcome of certain vesting requirements.

The 2019 Plan replaced the TriCo Bancshares 2009 Equity Incentive Plan (2009 Plan), which expired on March 26, 2019. As a result of its expiration, no further awards may be issued under the 2009 Plan, though all awards under the 2009 Plan that were outstanding as of its expiration continue to be governed by the terms, conditions and procedures set forth in the 2009 Plan and any applicable award agreement. As of December 31, 2022, 15,500 options for the purchase of common shares remain outstanding under the 2009 Plan.

The 139,194 of service condition vesting RSUs outstanding as of December 31, 2022 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. Additional RSUs credited through dividends are subject to the same vesting requirements as the original grant. The Company expects to recognize $3,822,000 of pre-tax compensation costs related to these service condition vesting RSUs between December 31, 2022 and their vesting dates. The Company did not modify any service condition vesting RSUs during 2022 or 2021.

The Company expects to recognize $2,110,000 of pre-tax compensation costs related to the market plus service condition RSUs between December 31, 2022 and their vesting dates. As of December 31, 2022, 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 171,721 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 2022 or 2021.

As part of the merger with FNB Bancorp in 2018 and North Valley Bancorp in 2014, TriCo acquired federal and state net operating loss carryforwards, capital loss carryforwards, and tax credit carryforwards. In addition, the 2020 Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) provided the Company with an opportunity to file amended federal tax returns and generate proposed refunds of approximately $805,000. These tax attribute carryforwards will be subject to provisions of the tax law that limit the use of such losses and

89 TriCo Bancshares 2022 10-K

credits generated by a company prior to the date certain ownership changes occur. The amount of the Company’s net operating loss carryforwards that are subject to these limitations as of December 31, 2022 were approximately $5,518,000 for federal and $11,187,000 for California. The amount of the Company’s tax credits that would be subject to these limitations as of December 31, 2022 are $395,000 and $648,000 for federal and California, respectively. Due to the limitation, a significant portion of the state tax credits will expire regardless of whether the Company generates future taxable income. As such, the Company has recorded the future benefit of these tax credits on the books at the value which is more likely than not to be realized. These tax loss and tax credit carryforwards expire at various dates through 2032.

The Company believes that a valuation allowance is not needed to reduce the deferred tax assets as it is more likely than not that the results of future operations will generate sufficient taxable income to realize the deferred tax assets, including the tax attribute carryforwards acquired as part of past mergers.

Disclosure of unrecognized tax benefits at December 31, 2022 and 2021 were not considered significant for disclosure purposes. Management does not expect the unrecognized tax benefit will materially change in the next 12 months. During the years ended December 31, 2022 and December 31, 2021 the Company did not recognize and significant amounts related to interest and penalties associated with taxes. The Company files income tax returns in the U.S. federal jurisdiction, and California. With few exceptions, the Company is no longer subject to U.S. federal and state/local income tax examinations by tax authorities for years before 2019 and 2018, respectively.

Note 21 – 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, such items, along with net income, are components of comprehensive income.

Note 22 – Retirement Plans

401(k) Plan

The Company sponsors a 401(k) Plan whereby substantially all employees age 21 and over with 90 days of service may participate. Participants may contribute a portion of their compensation subject to certain limits based on federal tax laws. The Company provides a discretionary matching contribution equal to 50% of participant’s elective deferrals, up to 4% of eligible compensation. The Company recorded salaries & benefits expense attributable to the 401(k) Plan matching contributions and 401(k) Plan matching contributions for the years ended:

Employee Stock Ownership Plan

Substantially all employees with at least one year of service are covered by a discretionary employee stock ownership plan (ESOP). Company shares owned by the ESOP are paid dividends and included in the calculation of earnings per share as common shares outstanding. Contributions are made to the plan at the discretion of the Board of Directors. Expenses related to the Company’s ESOP, included in benefits and other compensation costs under salaries and benefits expense, and contributions to the plan for the years ended were:

	Year Ended December 31,

ESOP contributions made by the Company	$	3,535	$	878	$	1,951

Deferred Compensation Plans

The Company has deferred compensation plans for certain directors and key executives, which allow certain directors and key executives designated by the Board of Directors of the Company to defer a portion of their compensation. The Company has purchased insurance on the lives of certain of the participants and intends to hold these policies until death as a cost recovery of the Company’s deferred compensation obligations of $5,738,000 and $5,945,000 at December 31, 2022 and 2021, respectively. Earnings credits on deferred balances included in non-interest expense are included in the following table:

Deferred compensation earnings credits included in non-interest expense	$	187	$	176	$	212

Supplemental Retirement Plans

The Company has supplemental retirement plans for certain directors and key executives. These plans are non-qualified defined benefit plans and are unsecured and unfunded. The Company has purchased insurance on the lives of the participants and intends to hold these policies until death as a cost recovery of the Company’s retirement obligations. The cash values of the insurance policies purchased to fund the deferred compensation obligations and the supplemental retirement obligations were $133,742,000 and $117,857,000 at December 31, 2022 and 2021, respectively.

The Company recorded in other liabilities the additional funded status of the supplemental retirement plans of $13,901,000 and $2,399,000 related to the supplemental retirement plans as of December 31, 2022 and 2021, respectively. These amounts represent the amount by which the projected benefit obligations for these retirement plans exceeded the fair value of plan assets plus amounts previously accrued related to the plans. The projected benefit obligation is recorded in other liabilities.

At December 31, 2022 and 2021, the additional funded status of the supplemental retirement plans of $13,901,000 and $2,399,000 were offset by a reduction of shareholders’ equity accumulated other comprehensive gain of $9,792,000 and $1,690,000, respectively, representing the after-tax impact of the additional funded status of the supplemental retirement plans, and the related deferred tax liability of $4,109,000 and $709,000, respectively. Amounts recognized as a component of accumulated other comprehensive income (loss) as of year-end that have not been recognized as a component of the combined net period benefit cost of the Company’s defined benefit pension plans are presented in the following table. The Company expects to recognize approximately $455,000 of the net actuarial loss reported in the following table as of December 31, 2022 as a component of net periodic benefit cost during 2022.

Note 24 – 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. Securities available-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 as loans held for sale, loans held for investment and certain other assets. These nonrecurring fair value adjustments typically involve application of lower of cost or market accounting or 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.

Securities available for sale—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

94 TriCo Bancshares 2022 10-K

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 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 nonrecurring 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, loans may require individual analysis and an allowance for credit losses is established. Loans for which it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement are an example. The fair value of individually evaluated loans is estimated using one of several methods, including collateral value, fair value of similar debt, enterprise value, liquidation value and discounted cash flows. Those individually evaluated 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. Individually evaluated 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 below the appraised value, or the appraised value contains a significant unobservable assumption, such as deviations from comparable sales, and there is no observable market price, the Company records the loan as nonrecurring Level 3.

Foreclosed assets—Foreclosed assets include assets acquired through, or in lieu of, loan foreclosure. Foreclosed assets are held for sale and are initially recorded at fair value at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, management periodically performs valuations and the assets are carried at the lower of carrying amount or fair value less cost to sell. When the fair value of foreclosed assets is based on an observable market price or a current appraised value which uses substantially observable data, the Company records the asset 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. Additional information regarding mortgage servicing rights can be found in Note 10 in the consolidated financial statements at Item 1 of this report.

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 2022 or 2021.

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 years ended December 31, 2022, 2021, and 2020. Had there been any transfer into or out of Level 3 during 2022, 2021, or 2020, 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):

Year ended December 31,	Beginning Balance		Transfers into (out of) Level 3	Change Included in Earnings		Issuances		Ending Balance
2022: Mortgage servicing rights	$	5,874	—	$	301	$	537	$	6,712
2021: Mortgage servicing rights	$	5,092	—	$	(872)	$	1,654	$	5,874
2020: Mortgage servicing rights	$	6,200	—	$	(2,634)	$	1,526	$	5,092

The Company’s method for determining the fair value of mortgage servicing rights is described in Note 1. 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). Note 10 contains additional information regarding mortgage servicing rights.

The individually evaluated loan amount above represents collateral dependent loans with unique risk characteristics that have been adjusted to fair value. When we identify a collateral dependent loan as requiring individual evaluation, we measure the need for credit reserves 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 we determine that the value of the loan is less than the recorded investment in the loan, we recognize this impairment and adjust the carrying value of the loan to fair value through the allowance for loan and lease 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 Bank 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 loan and lease losses. After foreclosure, management periodically performs valuations such that the real estate is carried at the lower of its new cost basis or fair value, net of estimated costs to sell. Fair value adjustments on other real estate owned are recognized within net loss on real estate owned. The loss represents impairments on non-covered other 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.

Overdraft privilege commitments (1)	126,634		1,266		125,670		1,257

The methods and assumptions used to estimate the fair value of each class of financial instruments not measured at fair value are as follows:

Securities held to maturity - This includes mortgage-backed securities issued by government sponsored entities and municipal bonds. 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.

Restricted equity securities - Consists of FHLB stock whereby carrying value approximates fair value.

Loans - Loans are generally valued by discounting expected cash flows using market inputs with adjustments based on cohort level assumptions for certain loan types as well as internally developed estimates at a business segment level. Due to the significance of the unobservable market inputs and assumptions, as well as the absence of a liquid secondary market for most loans, these loans are classified as Level 3. Certain loans are measured based on observable market prices sourced from external data providers and classified as Level 2. Nonaccrual loans are written down and reported at their estimated recovery value which approximates their fair value and classified as Level 3.

Deposits - The estimated fair value of deposits with no stated maturity, such as demand deposit accounts, money market accounts, and savings accounts was the amount payable on demand at the reporting date. The fair value of time deposits was estimated based on a discounted cash flow technique using Level 3 inputs appropriate to the contractual maturity.

Other borrowings - The cash flows were calculated using the contractual features of the advance and then discounted using observable market. These are short-term in nature.

Junior subordinated debt - The fair value of structured financings was estimated based on a discounted cash flow technique using observable market interest rates adjusted for estimated spreads.

(1) Lending related commitments - The fair value of these commitments, including revolving credit facilities, standby letters of credit and overdrafts are carried at contract value, which approximates fair value but are not actively traded. These instruments generate fees, which approximate those currently charged to originate similar commitments, which are recognized over the term of the commitment period.

Note 26 – Regulatory Matters

The Company and the Bank are 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 consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action specific capital guidelines that involve quantitative measures of assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. These 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 that minimum amounts and ratios of total, Tier 1, and common equity Tier 1capital to risk-weighted assets, and of Tier 1 capital to average assets be maintained. Under applicable capital requirements both the Company and the Bank are required to have a common equity Tier 1 capital ratio of 4.5%, a Tier 1 leverage ratio of 4.0%, a Tier 1 risk-based ratio of 6.0% and a total risk-based ratio of 8.0%. In addition, the Company and the Bank are also required to maintain a capital conservation buffer consisting of common equity Tier 1 capital above 2.5% of minimum risk based capital ratios to avoid restrictions on certain activities including payment of dividends, stock repurchases and discretionary bonuses to executive officers. The additional 2.5% buffer, where applicable, is included in the minimum ratios set forth in the table below. Management believes as of December 31, 2022 and 2021, the Company and Bank meet all capital adequacy requirements to which they are subject.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Management of TriCo Bancshares is responsible for establishing and maintaining effective internal control over financial reporting. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles.

Under the supervision and with the participation of management, including the principal executive officer and principal financial officer, the Company conducted an evaluation of the effectiveness of internal control over financial reporting based on the framework in the 2013 Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation under the framework in the 2013 Internal Control – Integrated Framework, management of the Company has concluded the Company maintained effective internal control over financial reporting, as such term is defined in Securities Exchange Act of 1934 Rules 13a-15(f), as of December 31, 2022.

Internal control over financial reporting cannot provide absolute assurance of achieving financial reporting objectives because of its inherent limitations. Internal control over financial reporting is a process that involves human diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human failures. Internal control over financial reporting can also be circumvented by collusion or improper management override. Because of such limitations, there is a risk that material misstatements may not be prevented or detected on a timely basis by internal control over financial reporting. However, these inherent limitations are known features of the financial reporting process. Therefore, it is possible to design into the process safeguards to reduce, though not eliminate, this risk.

Management is also responsible for the preparation and fair presentation of the consolidated financial statements and other financial information contained in this report. The accompanying consolidated financial statements were prepared in conformity with U.S. generally accepted accounting principles and include, as necessary, best estimates and judgments by management.

In addition to management’s assessment, Moss Adams LLP, an independent registered public accounting firm, has audited the Company’s consolidated financial statements as of and for the year ended December 31, 2022, and the Company’s effectiveness of internal control over financial reporting as of December 31, 2022, dated March 1, 2023, as stated in its report, which is included herein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Directors of

TriCo Bancshares

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of TriCo Bancshares (and subsidiaries) (the “Company”) as of December 31, 2022 and 2021, the related consolidated statements of income, comprehensive income, changes in shareholders’ equity, and cash flows for each of the three years in the period ended December 31, 2022, and the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company’s internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of the Company as of December 31, 2022 and 2021, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2022, in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control - Integrated Framework (2013) issued by COSO.

Basis for Opinions

The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s consolidated financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures to respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matter

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing a separate opinion on the critical audit matters or on the accounts or disclosures to which it relates.

Allowance for Credit Losses - Loan Risk Ratings, Reasonable and Supportable Forecasts and Qualitative Factors

As discussed in Note 1 and Note 5 to the consolidated financial statements, the Company’s allowance for credit losses for loans was $105,680,000 as of December 31, 2022, and consists of both historical credit loss experience and management’s estimates of current conditions and reasonable and supportable forecasts. The Company’s allowance for credit losses for loans is a valuation account that is deducted from the amortized cost basis of loans to present the net carrying value at the amount expected to be collected on such loans and is a material and complex estimate requiring significant management judgment in the estimation of expected lifetime losses within the loan portfolio at the balance sheet date.

We identified management’s risk rating of loans and the qualitative and environmental factors related to California’s unemployment and unemployment outlook, Global Economic Uncertainty, and US Policy Uncertainty, which are components of the reasonable and supportable forecasts, as critical audit matters. In estimating the allowance for credit losses on loans, the Company utilizes relevant information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. The Company considers relevant credit quality indicators for each loan segment, stratifies loans by risk rating, and estimates losses for each loan cohort based upon their nature, historical experience, and risk profile. This process requires significant management judgment in the review of the loan portfolio and assignment of risk ratings based upon the characteristics of loans. In addition, estimation of the lifetime expected credit losses for loans requires significant management judgment, particularly as it relates to forecast components of California’s unemployment and unemployment outlook, Global Economic Uncertainty and US Policy Uncertainty applied over the life of the loans. Auditing these complex judgments and assumptions involves especially challenging auditor judgment due to the nature and extent of audit evidence and effort required to address these matters.

The primary procedures we performed to address this critical audit matter included:

•Testing the design, implementation and operating effectiveness of controls relating to management’s calculation of the allowance for credit losses on loans, including controls over the review of loans and assignment of risk ratings and evaluation of the environmental and forecast factors related to California’s unemployment and unemployment outlook, Global Economic Uncertainty, and US Policy Uncertainty.

•Performing a sensitivity analysis to identify loan segments that would materially impact the allowance for credit losses due to risk rating changes as well as evaluating the appropriateness of the Company’s loan risk ratings and testing a risk-based targeted selection of loans to obtain substantive evidence that the Company is appropriately rating these loans in accordance with its policies, and that the risk ratings for the loans are reasonable.

•Evaluating the reasonableness and appropriateness of the estimated California unemployment factor and the estimated unemployment outlook forecast factor, the Global Economic Uncertainty outlook factor, and the US Policy Uncertainty outlook factor utilized by management in forming the environmental factor by comparing forecasts to relevant external data, including historical trends.

•Testing the mathematical accuracy and computation of the allowance for credit losses for loans by re-performing or independently calculating significant elements of the allowance and utilizing relevant source documents, including testing the completeness and accuracy of the data used in the calculation.

Business Combination – Valley Republic Bancorp acquired loans valuation

As discussed in Note 1 and Note 2 to the consolidated financial statements, on March 25, 2022, the Company completed the acquisition of Valley Republic Bancorp (VRB). Total merger consideration, including cash and stock transactions, was approximately $174 million. The fair value of total assets acquired as a result of the merger totaled $1.4 billion (net of cash consideration), with loans totaling $771 million, and resulting in $83.6 million of acquired goodwill. The merger was accounted for using the acquisition method of accounting in which assets, liabilities, and consideration exchanged were recorded at their respective fair values at the merger date. To estimate the fair value of the acquired loans, the Company utilized a discounted cash flow methodology that involved assumptions and judgments as to principal default and loss rates, prepayment rates, and market discount rates. The acquired loans were recorded at fair value at the acquisition date without carryover of VRB’s previously established allowance for loan losses.

We identified the valuation of acquired loans as a critical audit matter because of the judgments necessary by management to identify purchased loans with deteriorated credit quality since acquisition and to determine the fair value of the loan portfolio acquired, and the related high degree of auditor judgment and the extensive audit effort involved in testing management’s significant estimates and assumptions, including using individuals with specialized skill and knowledge.

105 TriCo Bancshares 2022 10-K

The primary procedures we performed to address this critical audit matter included:

•Testing the design, implementation and operating effectiveness of controls relating to the completeness and accuracy of acquired loan level data, and the fair value estimate of acquired loans, including significant assumptions and methods utilized in the calculation.

•Testing the completeness and accuracy of acquired loan level data used in the fair value estimate calculation.

•Testing the completeness and accuracy of loans identified as purchase credit deteriorated since origination and evaluating identification criteria utilized by management.

•Utilizing our internal valuation specialists to:

◦Test management’s approach to the fair value estimate for reasonableness.

◦Validate the reasonableness of assumptions utilized in the determination of the fair value of acquired loans, including the principal default and loss rates, prepayment rates and market discount rates assumptions.

◦Independently estimate the fair value of the acquired loans and compare it to the fair value recorded by management.

Exhibit 10.7

INDEMNIFICATION AGREEMENT

This Indemnification Agreement, dated as of _______, 20__, is made by and between TRI COUNTIES BANK, a California-chartered commercial bank (the “Bank”), and ____________________(the “Indemnitee”).

WHEREAS, it is essential to the Bank to retain and attract as directors and officers the most capable persons available;

WHEREAS, the Indemnitee is a director and/or officer of the Bank;

WHEREAS, the Bank and the Indemnitee recognize the increased risk of litigation and other claims being asserted against directors and officers of companies in today’s environment;

WHEREAS, Section 317 of the California Corporations Code, the Bank’s Articles of Incorporation (“Articles of Incorporation”) and the Bank’s Bylaws (“Bylaws”) authorize the Bank to indemnify and advance expenses to its directors and officers to the extent provided therein, and the Indemnitee serves as a director and/or officer of the Bank, in part, in reliance on such provisions;

WHEREAS, the Bank has determined that its inability to retain and attract as directors and officers the most capable persons would be detrimental to the interests of the Bank, and that the Bank therefore should seek to assure such persons that indemnification and insurance coverage will be available in the future; and

WHEREAS, in recognition of the Indemnitee’s need for substantial protection against personal liability in order to enhance the Indemnitee’s continued service to the Bank in an effective manner and the Indemnitee’s reliance on the Bank’s Articles of Incorporation and Bylaws, and in part to provide the Indemnitee with specific contractual assurance that the protection promised by the Bank’s Articles of Incorporation and Bylaws will be available to the Indemnitee (regardless of, among other things, any amendment to or revocation of the applicable provisions of the Bank’s Articles of Incorporation and Bylaws or any change in the composition of the governing bodies of the Bank or any acquisition transaction relating to the Bank), the Bank wishes to provide in this Agreement for the indemnification of and the advancing of expenses to the Indemnitee to the fullest extent (whether partial or complete) permitted by law and as set forth in this Agreement, and, to the extent insurance is maintained, for the continued coverage of the Indemnitee under the directors’ and officers’ liability insurance policy of the Bank.

NOW, THEREFORE, in consideration of the premises and of the Indemnitee continuing to serve the Bank directly or, on its behalf or at its request, as an officer, director, manager, member, partner, fiduciary or trustee of, or in a similar capacity with, another Person (as defined below) or any employee benefit plan, and intending to be legally bound hereby, the parties hereto agree as follows:

1.Certain Definitions. In addition to terms defined elsewhere herein, the following terms have the following meanings when used in this Agreement:

(a)Agreement: means this Indemnification Agreement, as amended from time to time hereafter.

A/75608141.1

(b)Board of Directors: means the Board of Directors of the Bank.

(c)Claim: means any threatened, asserted, pending or completed civil, criminal, administrative, investigative or other action, suit or proceeding of any kind whatsoever, including any arbitration or other alternative dispute resolution mechanism, or any appeal of any kind thereof, or any inquiry or investigation, whether instituted by the Bank, any governmental agency or any other party, that the Indemnitee in good faith believes might lead to the institution of any such action, suit or proceeding, whether civil, criminal, administrative, investigative or other, including any arbitration or other alternative dispute resolution mechanism.

(d)Indemnifiable Expenses: means (i) all expenses and liabilities, including judgments, fines, penalties, interest, amounts paid in settlement with the approval of the Bank, and counsel fees and disbursements (including, without limitation, experts’ fees, court costs, retainers, transcript fees, duplicating, printing and binding costs, as well as telecommunications, postage and courier charges) paid or incurred in connection with investigating, defending, being a witness in or participating in (including on appeal), or preparing to investigate, defend, be a witness in or participate in, any Claim relating to any Indemnifiable Event by reason of the fact that Indemnitee is, was or has agreed to serve as a director, officer, employee or agent of the Bank, or while serving as a director or officer of the Bank, is or was serving or has agreed to serve on behalf of or at the request of the Bank as a director, officer, manager, member, partner, fiduciary, trustee or in a similar capacity of another Person, or by reason of any action alleged to have been taken or omitted in any such capacity, whether occurring before, on or after the date of this Agreement (any such event, an “Indemnifiable Event”), (ii) any liability pursuant to a loan guaranty (other than a loan guaranty given in a personal capacity) or otherwise, for any indebtedness of the Bank or any subsidiary of the Bank, including, without limitation, any indebtedness which the Bank or any subsidiary of the Bank has assumed or taken subject to, and (iii) any liabilities which an Indemnitee incurs as a result of acting on behalf of the Bank (whether as a fiduciary or otherwise) in connection with the operation, administration or maintenance of an employee benefit plan or any related trust or funding mechanism (whether such liabilities are in the form of excise taxes assessed by the United States Internal Revenue Service, penalties assessed by the United States Department of Labor, restitutions to such a plan or trust or other funding mechanism or to a participant or beneficiary of such plan, trust or other funding mechanism, or otherwise).

(e)Indemnitee-Related Entities: means any corporation, limited liability company, partnership, joint venture, trust, employee benefit plan or other enterprise (other than the Bank or any other corporation, limited liability company, partnership, joint venture, trust, employee benefit plan or other enterprise Indemnitee has agreed, on behalf of the Bank or at the Bank’s request, to serve as a director, officer, employee or agent and which service is covered

2

A/75608141.1

by the indemnity described in this Agreement) from whom an Indemnitee may be entitled to indemnification or advancement of expenses with respect to which, in whole or in part, the Bank may also have an indemnification or advancement obligation (other than as a result of obligations under an insurance policy).

(f)Jointly Indemnifiable Claim: means any Claim for which the Indemnitee shall be entitled to indemnification from both an Indemnitee-Related Entity and the Bank pursuant to applicable law, any indemnification agreement or the articles of incorporation, bylaws, partnership agreement, operating agreement, certificate of formation, certificate of limited partnership or comparable organizational documents of the Bank and an Indemnitee-Related Entity.

(g)Loss: means all losses, Claims, damages, fines, or penalties, including, without limitation, any legal or other expenses (including, without limitation, any legal fees, judgments, fines, appeal bonds or related expenses) incurred in connection with defending, investigating or settling any Claim, fine, penalty or similar action.

(h)Person: means any individual, corporation, firm, partnership, joint venture, limited liability company, estate, trust, business association, organization, governmental entity or other entity.

2.Basic Indemnification Arrangement; Advancement of Indemnifiable Expenses.

(a)In the event that the Indemnitee was, is or becomes subject to, a party to or witness or other participant in, or is threatened to be made subject to, a party to or witness or other participant in, a Claim by reason of (or arising in part out of) an Indemnifiable Event, the Bank shall indemnify the Indemnitee, or cause such Indemnitee to be indemnified, to the fullest extent permitted by the laws of the State of California in effect on the date hereof and as amended from time to time, and shall hold the Indemnitee harmless from and against all Losses that arise by reason of (or arising in part out of) an Indemnifiable Event; provided, however, that no change in the laws of the State of California shall have the effect of reducing the benefits available to the Indemnitee hereunder based on the laws of the State of California as in effect on the date hereof or as such benefits may improve as a result of amendments after the date hereof. The rights of the Indemnitee provided in this Section 2 shall include, without limitation, the rights set forth in the other sections of this Agreement. Payments of Indemnifiable Expenses shall be made as soon as practicable but in any event no later than thirty (30) calendar days after written demand is presented to the Bank, against any and all Indemnifiable Expenses.

(b)Upon request by the Indemnitee, the Bank shall advance, or cause to be advanced, any and all Indemnifiable Expenses incurred by the Indemnitee (an “Expense Advance”) on the terms and subject to the conditions of this Agreement, as soon as practicable but in any event no later than thirty (30) calendar days after written demand, together with supporting documentation, is presented to the Bank. The Bank shall, in accordance with such request (but without duplication), either (i) pay, or cause to be paid, such Indemnifiable Expenses on behalf of the Indemnitee, or (ii) reimburse, or cause the reimbursement of, the Indemnitee for such Indemnifiable Expenses. The

3

A/75608141.1

Indemnitee’s right to an Expense Advance is absolute and shall not be subject to any condition that the Board of Directors shall not have determined that the Indemnitee is not entitled to be indemnified under applicable law. However, the obligation of the Bank to make an Expense Advance pursuant to this Section 2(b) shall be subject to the condition that, if, when and to the extent that a final judicial determination is made (as to which all rights of appeal therefrom have been exhausted or lapsed) that the Indemnitee is not entitled to be so indemnified under applicable law, the Bank shall be entitled to be reimbursed by the Indemnitee (who hereby agrees to reimburse the Bank) for all such amounts theretofore paid (it being understood and agreed that the foregoing agreement by the Indemnitee shall be deemed to satisfy any requirement that the Indemnitee provide the Bank with an undertaking to repay any Expense Advance if it is ultimately determined that the Indemnitee is not entitled to indemnification under applicable law). The Indemnitee’s undertaking to repay such Expense Advances shall be unsecured and interest-free.

(c)Notwithstanding anything in this Agreement to the contrary, the Indemnitee shall not be entitled to indemnification or advancement of Indemnifiable Expenses pursuant to this Agreement in connection with any Claim initiated by the Indemnitee unless (i) the Bank has joined in or the Board of Directors of the Bank has authorized or consented to the initiation of such Claim or (ii) the Claim is one to enforce the Indemnitee’s rights under this Agreement (including an action pursued by the Indemnitee to secure a determination that the Indemnitee should be indemnified under applicable law).

(d)The indemnification obligations of the Bank under Section 2(a) shall be subject to the condition that the Board of Directors shall not have determined (by majority vote of directors who are not parties to the applicable Claim) that the indemnification of the Indemnitee is not proper in the circumstances because the Indemnitee is not entitled to be indemnified under applicable law. If the Board of Directors determines that the Indemnitee is not entitled to be indemnified in whole or in part under applicable law, the Indemnitee shall have the right to commence litigation in any court in the State of California having subject matter jurisdiction thereof and in which venue is proper, seeking an initial determination by the court or challenging any such determination by the Board of Directors or any aspect thereof, including the legal or factual bases therefor, and the Bank hereby consents to service of process and to appear in any such proceeding. If the Indemnitee commences legal proceedings in a court of competent jurisdiction to secure a determination that the Indemnitee should be indemnified under applicable law, any determination made by the Board of Directors that the Indemnitee is not entitled to be indemnified under applicable law shall not be binding, the Indemnitee shall continue to be entitled to receive Expense Advances, and the Indemnitee shall not be required to reimburse the Bank for any Expense Advance, until a final judicial determination is made in the Claim (as to which all rights of appeal therefrom have been exhausted or lapsed) that the Indemnitee is not entitled to be so indemnified under applicable law. Any determination by the Board of Directors otherwise shall be conclusive and binding on the Bank and the Indemnitee.

(e)To the extent that the Indemnitee has been successful on the merits or otherwise in defense of any or all Claims relating in whole or in part to an Indemnifiable Event or in defense of any issue or matter therein, including dismissal without prejudice, the Indemnitee shall be indemnified against all Indemnifiable Expenses actually and reasonably incurred in connection therewith, notwithstanding an earlier determination by the Board of Directors that the Indemnitee is not entitled to indemnification under applicable law.

4

A/75608141.1

(f)Notwithstanding anything to the contrary herein, the Bank shall not be obligated pursuant to the terms of this Agreement to indemnify Indemnitee for any acts or omissions or transactions from which a director, officer, employee or agent may not be relieved of liability under applicable law.

(g)Notwithstanding any other provisions contained herein, this Agreement and the rights and obligations of the parties hereto are subject to the requirements, limitations and prohibitions set forth in state and federal laws, rules, regulations, and orders regarding indemnification and prepayment of expenses, legal or otherwise, and liabilities, including, without limitation, Section 317 of the California Corporations Code, Section 18(k) of the Federal Deposit Insurance Act and Part 359 of the Federal Deposit Insurance Corporation’s Rules and Regulations and any successor regulations thereto.

3.Indemnification for Additional Expenses. The Bank shall indemnify, or cause the indemnification of, the Indemnitee against any and all Indemnifiable Expenses and, if requested by the Indemnitee, shall advance such Indemnifiable Expenses to the Indemnitee subject to and in accordance with Section 2, which are incurred by the Indemnitee in connection with any action brought by the Indemnitee, the Bank or any other Person with respect to the Indemnitee’s right to: (i) indemnification or an Expense Advance by the Bank under this Agreement or any provision of the Bank’s Articles of Incorporation and/or Bylaws and/or (ii) recovery under any directors’ and officers’ liability insurance policies maintained by the Bank, regardless of whether the Indemnitee ultimately is determined to be entitled to such indemnification, Expense Advance or insurance recovery, as the case may be; provided that the Indemnitee shall be required to reimburse such Indemnifiable Expenses in the event that a final judicial determination is made in the Claim (as to which all rights of appeal therefrom have been exhausted or lapsed) that such action brought by the Indemnitee, or the defense by the Indemnitee of an action brought by the Bank or any other Person, as applicable, was frivolous or in bad faith.

4.Partial Indemnity, Etc. If the Indemnitee is entitled under any provision of this Agreement to indemnification by the Bank for some or a portion of the Indemnifiable Expenses in respect of a Claim but not, however, for all of the total amount thereof, the Bank shall nevertheless indemnify the Indemnitee for the portion thereof to which the Indemnitee is entitled.

5.Burden of Proof. In connection with any determination by the Board of Directors, any court or otherwise as to whether the Indemnitee is entitled to be indemnified hereunder, the Board of Directors or court shall presume that the Indemnitee has satisfied the applicable standard of conduct and is entitled to indemnification, and the burden of proof shall be on the Bank or its representative to establish, by clear and convincing evidence, that the Indemnitee is not so entitled.

6.Reliance as Safe Harbor. The Indemnitee shall be entitled to indemnification for any action or omission to act undertaken (a) in good faith reliance upon the records of the Bank, including its financial statements, or upon information, opinions, reports or statements furnished to the Indemnitee by the officers or employees of the Bank or any of its subsidiaries in the course of their duties, or by committees of the Board of Directors, or by any other Person as to matters the Indemnitee reasonably believes are within such other Person’s professional or expert competence, or (b) on behalf of the Bank in furtherance of the interests of the Bank in good faith in reliance upon, and in accordance with, the advice of legal counsel or accountants, provided such legal counsel or accountants were selected with reasonable care by or on behalf of the

5

A/75608141.1

Bank. In addition, the knowledge and/or actions, or failures to act, of any other director, officer, agent or employee of the Bank shall not be imputed to the Indemnitee for purposes of determining the right to indemnity hereunder.

7.No Other Presumptions. For purposes of this Agreement, the termination of any Claim, action, suit or proceeding, by judgment, order, settlement (whether with or without court approval) or conviction, or upon a plea of nolocontendere or its equivalent, shall not create a presumption that the Indemnitee did not meet any particular standard of conduct or have any particular belief or that a court has determined that indemnification is not permitted by applicable law. In addition, neither the failure of the Board of Directors to have made a determination as to whether the Indemnitee has met any particular standard of conduct or had any particular belief, nor an actual determination by the Board of Directors that the Indemnitee has not met such standard of conduct or did not have such belief, prior to the commencement of legal proceedings by the Indemnitee to secure a judicial determination that the Indemnitee should be indemnified under applicable law shall be a defense to the Indemnitee’s claim or create a presumption that the Indemnitee has not met any particular standard of conduct or did not have any particular belief.

8.Nonexclusivity, Etc. The rights of the Indemnitee hereunder shall be in addition to any other rights the Indemnitee may have under the Bank’s Articles of Incorporation and Bylaws, the laws of the State of California, or otherwise. To the extent that a change in the laws of the State of California or the interpretation thereof (whether by statute or judicial decision) permits greater indemnification by agreement than would be afforded currently under the Bank’s Articles of Incorporation and Bylaws, it is the intent of the parties hereto that the Indemnitee shall enjoy by this Agreement the greater benefits so afforded by such change. To the extent that there is a conflict or inconsistency between the terms of this Agreement and the Bank’s Articles of Incorporation or Bylaws, it is the intent of the parties hereto that the Indemnitee shall enjoy the greater benefits regardless of whether contained herein, in the Bank’s Articles of Incorporation or Bylaws. No amendment or alteration of the Bank’s Articles of Incorporation or Bylaws or any other agreement shall adversely affect the rights provided to Indemnitee under this Agreement.

9.Liability Insurance. The Bank shall use its reasonable best efforts to purchase and maintain a policy or policies of insurance with reputable insurance companies with A.M. Best ratings of “A” or better, providing Indemnitee with coverage for any liability asserted against, or incurred by, Indemnitee or on Indemnitee’s behalf by reason of the fact that Indemnitee is or was or has agreed to serve as a director, officer, employee or agent of the Bank, or while serving as a director or officer of the Bank, is or was serving or has agreed to serve on behalf of or at the request of the Bank as a director, officer, employee or agent (which, for purposes hereof, shall include a trustee, fiduciary, partner or manager or similar capacity) of another corporation, limited liability company, partnership, joint venture, trust, employee benefit plan or other enterprise, or arising out of Indemnitee’s status as such, whether or not the Bank would have the power to indemnify Indemnitee against such liability under the provisions of this Agreement. Such insurance policies shall have coverage terms and policy limits at least as favorable to Indemnitee as the insurance coverage provided to any other director or officer of the Bank. If the Bank has such insurance in effect at the time the Bank receives from Indemnitee any notice of the commencement of an action, suit or proceeding, the Bank shall give prompt notice of the commencement of such action, suit or proceeding to the insurers in accordance with the procedures set forth in the policy. The Bank shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of

6

A/75608141.1

Indemnitee, all amounts payable as a result of such proceeding in accordance with the terms of such policy.

10.Amendments, Etc. No supplement, modification or amendment of this Agreement shall be binding unless executed in writing by both of the parties hereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provisions hereof (whether or not similar) nor shall such waiver constitute a continuing waiver. In the event the Bank or any of its subsidiaries enters into an indemnification agreement with another director, officer, agent, fiduciary or manager of the Bank or any of its subsidiaries containing a term or terms more favorable to the indemnitee than the terms contained herein (as determined by the Indemnitee), the Indemnitee shall be afforded the benefit of such more favorable term or terms and such more favorable term or terms shall be deemed incorporated by reference herein as if set forth in full herein. As promptly as practicable following the execution by the Bank or the relevant subsidiary of each indemnity agreement with any such other director, officer or manager (i) the Bank shall send a copy of the indemnity agreement to the Indemnitee, and (ii) if requested by the Indemnitee, the Bank shall prepare, execute and deliver to the Indemnitee an amendment to this Agreement containing such more favorable term or terms.

11.Subrogation. Subject to Section 12, in the event of payment by the Bank under this Agreement, the Bank shall be subrogated to the extent of such payment to all of the rights of recovery of the Indemnitee with respect to any insurance policy. Indemnitee shall execute all papers reasonably required and shall do everything that may be reasonably necessary to secure such rights, including the execution of such documents necessary to enable the Bank effectively to bring suit to enforce such rights. The Bank shall pay or reimburse all expenses actually and reasonably incurred by Indemnitee in connection with such subrogation.

12.Jointly Indemnifiable Claims. Given that certain Jointly Indemnifiable Claims may arise due to the relationship between the Indemnitee-Related Entities and the Bank and the service of the Indemnitee as a director and/or officer of the Bank at the request of the Indemnitee-Related Entities, the Bank acknowledges and agrees that the Bank shall be fully and primarily responsible for the payment to the Indemnitee in respect of indemnification and advancement of Indemnifiable Expenses in connection with any such Jointly Indemnifiable Claim, pursuant to and in accordance with the terms of this Agreement, irrespective of any right of recovery the Indemnitee may have from the Indemnitee-Related Entities. Under no circumstance shall the Bank be entitled to any right of subrogation or contribution by the Indemnitee-Related Entities and no right of recovery the Indemnitee may have from the Indemnitee-Related Entities shall reduce or otherwise alter the rights of the Indemnitee or the obligations of the Bank hereunder. In the event that any of the Indemnitee-Related Entities shall make any payment to the Indemnitee in respect of indemnification or advancement of expenses with respect to any Jointly Indemnifiable Claim, the Indemnitee-Related Entity making such payment shall be subrogated to the extent of such payment to all of the rights of recovery of the Indemnitee against the Bank under the terms of this Agreement, and the Indemnitee shall execute all papers reasonably required and shall do all things that may be reasonably necessary to secure such rights, including the execution of such documents as may be necessary to enable the Indemnitee-Related Entities effectively to bring suit to enforce such rights. Each of the Indemnitee-Related Entities shall be third-party beneficiaries with respect to this Section 12, entitled to enforce this Section 12 against the Bank as though each such Indemnitee-Related Entity were a party to this Agreement.

7

A/75608141.1

13.No Duplication of Payments. Subject to Section 12 hereof, the Bank shall not be liable under this Agreement to make any payment in connection with any Claim made against the Indemnitee to the extent the Indemnitee has otherwise actually received payment (under any insurance policy, any provision of the Bank’s Articles of Incorporation and Bylaws, or otherwise) of the amounts otherwise indemnifiable hereunder.

14.Defense of Claims. The Bank shall be entitled to participate in the defense of any Claim relating to an Indemnifiable Event or to assume the defense thereof, with counsel reasonably satisfactory to the Indemnitee; provided that if the Indemnitee reasonably believes, after consultation with counsel selected by the Indemnitee, that (i) the use of counsel chosen by the Bank to represent the Indemnitee would present such counsel with an actual or potential conflict of interest, (ii) the named parties in any such Claim (including any impleaded parties) include both (A) the Bank or any subsidiary of the Bank and (B) the Indemnitee, and the Indemnitee concludes that there may be one or more legal defenses available to him that are different from or in addition to those available to the Bank or any subsidiary of the Bank or (iii) any such representation by such counsel would be precluded under the applicable standards of professional conduct then prevailing, then the Indemnitee shall be entitled to retain separate counsel (but not more than one law firm plus, if applicable, local counsel in respect of any particular Claim) at the Bank’s expense. The Bank shall not be liable to the Indemnitee under this Agreement for any amounts paid in settlement of any Claim relating to an Indemnifiable Event effected without the Bank’s prior written consent. The Bank shall not, without the prior written consent of the Indemnitee, effect any settlement of any Claim relating to an Indemnifiable Event which the Indemnitee is or could have been a party unless such settlement solely involves the payment of money and includes a complete and unconditional release of the Indemnitee from all liability on all claims that are the subject matter of such Claim. Neither the Bank nor the Indemnitee shall unreasonably withhold its or his consent to any proposed settlement; provided that the Indemnitee may withhold consent to any settlement that does not provide a complete and unconditional release of the Indemnitee. To the fullest extent permitted by California law, the Bank’s assumption of the defense of a Claim pursuant to this Section 14 will constitute an irrevocable acknowledgement by the Bank that any Indemnifiable Expenses incurred by or for the account of Indemnitee incurred in connection therewith are indemnifiable by the Bank under Section 2 of this Agreement.

15.Binding Effect, Etc. This Agreement shall be binding upon and inure to the benefit of and be enforceable by the parties hereto and their respective successors, (including any direct or indirect successor by purchase, merger, consolidation or otherwise to all or substantially all of the business and/or assets of the Bank), assigns, spouses, heirs, executors and personal and legal representatives. The Bank shall require and cause any successor(s) (whether directly or indirectly, whether in one or a series of transactions, and whether by purchase, merger, consolidation, or otherwise) to all or a significant portion of the business and/or assets of the Bank and/or its subsidiaries (on a consolidated basis), by written agreement in form and substance reasonably satisfactory to the Indemnitee, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Bank would be required to perform if no such succession had taken place; provided that no such assumption shall relieve the Bank from its obligations hereunder and any obligations shall thereafter be joint and several. This Agreement shall continue in effect regardless of whether the Indemnitee continues to serve as a director or officer of the Bank and/or on behalf of or at the request of the Bank as a director, officer, manager, member, partner, fiduciary, trustee or in a similar capacity of another Person. Except as provided in this Section 15, neither party shall, without the

17.Specific Performance, Etc. The parties recognize that if any provision of this Agreement is violated by the parties hereto, the Indemnitee may be without an adequate remedy at law. Accordingly, in the event of any such violation, the Indemnitee shall be entitled, if the Indemnitee so elects, to institute proceedings, either in law or at equity, to obtain damages, to enforce specific performance, to enjoin such violation, or to obtain any relief or any combination of the foregoing as the Indemnitee may elect to pursue.

THE RESTATED 2005 TRI COUNTIES BANK
DEFERRED COMPENSATION PLAN FOR EXECUTIVES AND DIRECTORS

This Restated Tri Counties Bank Deferred Compensation Plan for Executives and Directors is effective January 1, 2021. Directors serving on the Board and certain designated Executives who are employed by TriCo Bancshares, Tri Counties Bank, and subsidiaries or affiliates thereof (hereinafter, these entities shall be referred to as the “Bank” or the “Employer”) on or after January 1, 2005 are eligible to participate.. It is intended that the Plan will aid in retaining and attracting individuals of exceptional ability by providing them with these benefits.

ARTICLE I –PURPOSE

The purpose of this Deferred Compensation Plan for Executives and Directors (the “Plan”) is to provide current tax planning opportunities, as well as supplemental funds for retirement or death, for Executives and Directors of the Employer. It is also intended that the Plan will aid in retaining and attracting Executives and Directors of exceptional ability by providing them with these benefits. The Plan was originally adopted effective January 1, 2005, and was amended and restated as of that date principally to clarify certain provisions governed by section 409A of the Internal Revenue Code of 1986, as amended (“IRC 409A”), and to reflect the Plan operations under IRC 409A since January 1, 2005. The Employer wishes to further amend the Plan effective January 1, 2021 to address future interest rates paid on the plan.

ARTICLE II –DEFINITIONS

For the purposes of this Plan, the following terms shall have the meanings indicated, unless the context clearly indicates otherwise:

1.1Participant

The term “Participant” shall mean those designated Executives or Directors of the Employer who are participating in this Plan as provided in Article III.

1.2Plan Benefit

“Plan Benefit” means the benefit payable to a Participant as calculated pursuant to Articles IV through V.

1.3Board

“Board” means the Board of Directors of the Employer.

1.4Committee

“Committee” means the Compensation and Management Succession Committee of TriCo Bancshares.

1.5Compensation

As it applies to an Executive, the term “Compensation” shall refer to the salary, bonuses or commissions paid to the Executive during employment with Employer for services performed during a given Deferral Period. The Deferral Period to which a commission relates shall be the Deferral Period when the Executive actually performs the services for which the commission is paid. The Deferral Period to which a bonus relates shall be the Deferral Period when the Executive actually performs the services for which the bonus is paid. As it applies to a Director,

{00140563.DOC /4 }

1

“Compensation” shall refer to the retainer, meeting and Committee chairmanship fees paid to a Director by the Employer with respect to services performed as a Board member during a given Deferral Period, before reduction for any amounts deferred pursuant to this Plan. Compensation does not include expense reimbursements, any form of non-cash compensation or benefits. Compensation payable after December 31 of a given Deferral Period solely for services performed during the Employer’s final payroll period containing that December 31 is treated as Compensation payable for services performed in the subsequent Deferral Period in which the Compensation is paid.

1.6Elective Deferred Compensation

The term “Elective Deferred Compensation” shall mean the amount of Compensation that a Participant elects to defer pursuant to a Deferral Election Form.

1.7Deferral Election

“Deferral Election” means an irrevocable election to defer Compensation made by a Participant pursuant to Article III and for which a Deferral Election Form, as prescribed by the Committee, has been timely submitted by the Participant to the Committee (or one or more officers designated by the Committee). Except as expressly provided herein, the Deferral Election with respect to any particular Deferral Period cannot be modified or revoked after the deadline provided in Section 3.1 for submitting the Deferral Election Form to the Committee for that Deferral Period. The Committee may prescribe any Deferral Election Form that is consistent with the terms of this Plan.

1.8Deferral Period

“Deferral Period” means the period over which a Participant has elected to defer a portion of his or her Compensation. Each calendar year shall be a separate Deferral Period. For commissions and bonuses, the Deferral Period shall be the Deferral Period when the Executive actually performs the services for which the bonus or commission is paid, regardless of when the commission or bonus is actually awarded or paid. By way of example, if a bonus is awarded in 2010 for services performed in calendar year 2009, then calendar year 2009 is the Deferral Period for that bonus, and any election to defer that bonus must be submitted to the Committee on a valid Deferral Election Form by December 31, 2008, as provided in Section 3.1.

1.9Account

“Account” means the bookkeeping Account as maintained by the Bank in accordance with Article IV with respect to any deferral of Compensation pursuant to this Plan. A Participant’s Account shall be utilized solely as a device for the determination and measurement of the amounts to be paid to the Participant pursuant to the Plan. A Participant’s Account shall not constitute or be treated as a trust fund of any kind.

1.10Distribution Election

The term “Distribution Election” shall mean the form of distribution of the Account selected by the Participant on the most recent valid and timely submitted Distribution Election Form. The Committee may prescribe any Distribution Election Form that is consistent with the terms of this Plan.

1.11Determination Date

“Determination Date” means the last day of each calendar month.

{00140563.DOC /4 }    2

1.12Interest Rate

Effective January 1, 2021, “Interest Rate” means the interest rate, index, or other measure set by the Board of Directors prior to the beginning of a Plan Year for that Plan Year. If the Board does not change the Interest Rate for a Plan Year, then the rate, index, or other measure set by the Board for the prior year shall continue in effect until changed.

For Participants who entered the Plan and began participation prior to January 1, 2014, deferral balances as of December 31, 2020 shall continue to be credited with interest at the monthly equivalent of the annual yield of the Moody’s Average Corporate Bond Yield Index for the preceding calendar month as published by Moody’s Investor Service, Inc. (or any successor thereto) or, if such index is no longer published, a substantially similar index selected by the Board.

1.13Bonus Interest Rate

Effective January 1, 2021, no “Bonus Interest Rate” will be paid on deferrals during a Plan Year beginning on or after January 1, 2021. Deferral balances as of December 31, 2020 shall continue to be credited with a “Bonus Interest Rate” which is the monthly equivalent of one (1) percentage point greater than the annual yield of the Moody’s Average Corporate Bond Yield Index for the preceding calendar month as published by Moody’s Investor Service, Inc. (or any successor) or, if such index is no longer published, a similar index selected by the Board.

1.14Change in Control

A “Change in Control” means the occurrence of any of the following events with respect to Tri Counties Bank (as used in this Section 2.14, the “Bank”) or its parent holding company, TriCo Bancshares (as used in this Section 2.14 “Bancorp”):

(a)Merger: A merger into or consolidation with another corporation, or merger of another corporation into Bank or Bancorp, and as a result less than 50% of the combined voting power of the resulting corporation immediately after the merger or consolidation is held by persons who were stockholders of the Bank or Bancorp immediately before the merger or consolidation;

(b)Acquisition of Significant Share Ownership: One person, or more than one person acting as a group, acquires (or has acquired during the twelve (12) month period ending on the date of the most recent acquisition by such person or persons) ownership of stock possessing thirty percent (30%) or more of the total voting power of the stock of the Bank or Bancorp (this constitutes acquisition of “Effective Control”). No Change in Control shall occur if additional voting shares are acquired by a person or persons who possessed Effective Control prior to acquiring additional shares. This subpart (b) shall not apply to beneficial ownership of voting shares held in a fiduciary capacity by an entity of which Bank or Bancorp directly or indirectly beneficially owns fifty percent (50%) or more of the outstanding voting securities, or voting shares held by an employee benefit plan maintained for the benefit of the Bank’s employees.

(c)Change in Board Composition: A majority of the members of the Board of Directors of the Bank or Bancorp is replaced during any twelve (12) month period by directors whose appointment or election is not endorsed by a majority of the members of the Board of Directors of the Bank or Bancorp before the date of the appointment or election. This subparagraph shall only apply with respect to Bancorp if no other corporation is a majority shareholder of Bancorp.

{00140563.DOC /4 }    3

(d)A sale of substantially all of the assets of the Bank or Bancorp.

A Change in Control shall only occur with respect to Bancorp if Bancorp (i) is a majority shareholder of the Bank; (ii) is a majority shareholder of any corporation in a chain of corporations in which each corporation is a majority shareholder of another corporation in the chain, ending in the Bank; or (iii) is otherwise a “Relevant Corporation” as that term is used and defined in IRC 409A. For purposes of this section, majority shareholder means a shareholder owning more than fifty percent (50%) of the total fair market value and total voting power of the Bank, Bancorp, or a corporation in the chain referenced above. No Change in Control shall occur unless the event constitutes a “Change in the Ownership of a Corporation,” a “Change in the Effective Control of a Corporation,” or a “Change in the Ownership of a Substantial Portion of the Assets of a Corporation,” as defined under IRC 409A.

1.15Disability

For the purpose of this Plan, the Participant will be considered disabled if:

(a)The Participant is unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be expected to result in death or can be expected to last for a continuous period of not less than twelve (12) months, or

(b)The Participant is, by reason of any medically determinable physical or mental impairment which can be expected to result in death or can be expected to last for a continuous period of not less than twelve (12) months, receiving income replacement benefits for a period of not less than three (3) months under an accident and health plan covering employees of the Participant’s employer.

1.16Termination or Removal For Cause

A Termination of an Executive’s employment or a Removal of a Director shall be “For Cause” if for any of the following reasons:

(a)Gross negligence or gross neglect;

(b)The commission of a felony, misdemeanor, or any other act involving moral turpitude, fraud, or dishonesty which has a material adverse impact on the Bank;

(c)The willful and intentional disclosure, without authority, of any secret or confidential information concerning the Bank that has a material adverse impact on the Bank; or

(d)The willful and intentional violation of the rules or regulations of any regulatory agency or government authority having jurisdiction over the Bank, which has a material adverse impact on the Bank.

1.17Unforeseeable Emergency

For the purposes of this Plan, an “Unforeseeable Emergency” shall mean a severe financial hardship to the Participant due to (a) uninsured medical expenses resulting from an illness or accident of the Participant, the Participant’s spouse, or a dependent of the Participant (as defined in IRC 152(a) without regard to IRC 152(b)(1), 152(b)(2) and 152(d)(1)(B)); (b) an uninsured casualty loss pertaining to property owned by the Participant; or, (c) other similar extraordinary and unforeseeable circumstances involving an uninsured loss arising as a result of

{00140563.DOC /4 }    4

an event beyond the control of the Participant, provided however that any such event qualifies as an “unforeseeable emergency” within the meaning of IRC 409A.

1.18Lifetime Deferral Limit

Total deferred compensation is subject to a lifetime limit of one million five hundred thousand dollars ($1,500,000.00) and includes all deferred compensation under this Plan or any prior deferred compensation plan established or maintained by the Employer.

1.19Beneficiary

In addition, such Deferral Election Form shall be effective only with regard to Compensation earned for services performed following the submission of the Deferral Election Form to the Committee (determined on a pro-rata basis to the extent required by Treasury regulation 1.409A-2(a)(7)(i)). The determination of when a Participant first becomes eligible to participate in the Plan shall be made according to Treasury regulation 1.409A-2(a)(7)(ii).

Notwithstanding any provision in this Section 3.2 to the contrary, the Committee may authorize a deferral election to the extent consistent with the transition rules and during the transition relief period provided under IRC 409A and the related guidance issued in Treasury regulations and by the Internal Revenue Service.

ARTICLE IV –DEFERRED COMPENSATION ACCOUNT

4.1Accounts

For record keeping purposes only, an Account shall be maintained for each Participant.

4.2Elective Deferred Compensation

A Participant’s Elective Deferred Compensation shall be credited to the Participant’s Account as the corresponding non-deferred portion of the Compensation becomes or would have become payable. Any withholding of taxes or other amounts with respect to Elective Deferred Compensation that is required by state, federal or local law shall be withheld from the Participant’s non-deferred Compensation to the maximum extent possible with any excess being withheld from the Participant’s Account. Any such withholding of taxes or other amounts from the Participant’s Account shall comply with Treasury regulation 1.409A-3(j)(4)(vi) and 1.409A-3(j)(4)(xi), to the extent applicable.

4.3Employer Discretionary Contributions

The Employer may make Discretionary Contributions to Participants’ Accounts. Discretionary Contributions shall be credited at such times and in such amounts, with such vesting provisions, as the Board in its sole discretion shall determine.

4.4Interest

Effective January 1, 2020, and subject to the provisions of Section 5.4 with respect to a Termination for Cause, each Participant’s Account shall be credited monthly with interest earned based on the Interest Rate, provided however, no Bonus Interest Rate shall be paid on deferrals for Plan Years beginning on or after January 1, 2021. Interest earned shall be calculated as of each Determination Date based upon the average daily balance of the Account since the preceding Determination Date and shall be credited to the Participant’s Account at that time. For each Determination Date preceding the Participant’s Separation from Service (including a Separation from Service after a Change in Control), as defined in Section 5.4, the deferral balances as of December 31, 2020 shall continue to be credited with interest earned at the Bonus

{00140563.DOC /4 }    6

Interest Rate specified in Section 2.13. Following a Participant’s Separation from Service (including a Separation from Service after a Change in Control), the Participant’s Account shall be credited with interest earned at the Interest Rate specified in Section 2.12.

4.5Determination of Accounts

Each Participant’s Account as of each Determination Date shall consist of the balance of the Participant’s Account as of the immediately preceding Determination Date, plus the Participant’s Elective Deferred Compensation credited and any Employer Discretionary Contributions and any interest earned, minus the amount of any distributions made since the immediately preceding Determination Date.

4.6Vesting of Accounts

Each Participant shall be vested in the amounts credited to such Participant’s Account and earnings thereon as follows:

(a)Amounts Deferred. Except in the event of Termination for Cause, a Participant shall be one hundred percent (100%) vested at all times in the amount of Compensation elected to be deferred under this Plan and Interest thereon, subject to the provisions of Section 5.6.

(b)Employer Discretionary Contributions. Employer Discretionary Contributions and Interest thereon shall be vested as determined by the Board at the time such contributions are made. Unvested Employer Discretionary Contributions shall be forfeited on Termination of Employment.

4.7Statement of Accounts

The Bank shall submit to each Participant, within thirty (30) days after the close of each calendar year and at such other time as determined by the Bank, a statement setting forth the balance to the credit of the Account maintained for a Participant.

ARTICLE V –PLAN BENEFITS

4.1Plan Benefit

The Employer shall pay a Plan Benefit according to the provisions of this Article V.

4.2Death Benefit

Upon receiving notice of the death of a Participant, the Employer shall pay to the Participant’s Beneficiary(ies) a Plan Benefit as follows:

(a)If the Participant dies after payment has begun pursuant to the terms of this Plan, then the amount payable shall be the remaining unpaid balance of the Participant’s Account, and shall be paid in the same form as payments were being made prior to the Participant’s death.

(b)If the Participant dies while serving as an Executive or Director of the Employer, or before payment has begun pursuant to the terms of this Plan, then the amount payable shall be equal to the Participant’s Account, and shall be payable as provided in Section 5.4.

{00140563.DOC /4 }    7

Any notice required under this provision shall be in writing and shall include an original death certificate.

4.3Unforeseeable Emergency Distributions

A Participant may request a distribution on account of an Unforeseeable Emergency, which may or may not be granted as determined by the Committee. Upon a finding that a Participant has suffered an Unforeseeable Emergency, the Committee may, in its sole discretion, make distributions from the Participant’s Account prior to the time specified for payment. Any distribution made pursuant to this provision must be made in accordance with IRC 409A and the related Treasury regulations, and must not exceed the amount determined by the Committee to be reasonably necessary (including anticipated taxes on the distribution) to meet the emergency financial need and not reasonably available from other resources of the Participant (including reimbursement or compensation by insurance, liquidation of the Participant’s assets to the extent such liquidation itself would not cause severe financial hardship, or by cessation of deferrals under this Plan). In making this determination, the Committee will take into account any additional compensation that is available to the Participant. Each request for distribution due to an Unforeseeable Emergency shall be made at such time and in such manner as the Committee shall prescribe from time to time. Any distribution under this Section 5.3 shall be paid to the Participant in a single lump sum as soon as administratively practicable following receipt of the appropriate forms and information required by and acceptable to the Committee. Notwithstanding anything to the contrary, in the event a Participant receives a distribution from the Plan on account of an Unforeseeable Emergency, his or her deferral election will be cancelled with respect to any deferrals that would occur for the remainder of the Deferral Period after the Unforeseeable Emergency distribution.

4.4Distribution Following a Separation From Service

Upon a Separation from Service, a Participant shall be entitled to a Plan Benefit equal to the balance credited to the Participant’s Account. However, in the event of a Termination for Cause, notwithstanding the preceding sentence, the entire balance of the Participant’s Account shall be forfeited and the Participant shall not be entitled to any Plan Benefit. A Separation from Service means the Participant’s separation from service (within the meaning of IRC 409A and related Treasury regulations and Internal Revenue Service guidance, including death or Disability) from the Employer, and any Related Employer as defined in IRC 414(b) and (c). A Separation from Service shall occur as of the date that the Employer and Participant reasonably anticipate that the Participant will have a permanent reduction in the level of bona fide services provided to the Employer or any Related Employer to a level of service that is less than twenty percent (20%) of the average level of services performed in the immediately preceding thirty-six (36) month period.

In the event, however, that the Participant is a Specified Employee at the time of Separation from Service, the Participant’s right to receive any distribution will be delayed until the earlier of the Participant’s death or the first day of the seventh month following Separation from Service. In the event that the six (6) month delay applies to a Participant, payments that would have been made during the six (6) month period, but for this section, will be paid on the first day of the seventh month following the Participant’s Separation from Service and, if applicable, regular payments will continue thereafter. “Specified Employee” shall mean the following: If a Participant is a Key Employee (defined below) of the Employer or any entity that is aggregated with the Employer under IRC 414(b) or (c) as of December 31st of any year (the “Determination Date”), and the Employer (or any entity that is aggregated with the Employer under IRC 414(b) or (c)) has stock that is publicly traded on an established securities market or otherwise, then the Participant shall be treated as a Specified Employee during the twelve (12) month period beginning on the April 1st following the Determination Date. A Participant is a

{00140563.DOC /4 }    8

Key Employee as of a Determination Date if the Participant meets the requirements of IRC 416(i)(1)(A)(i), (ii), or (iii) (applied in accordance with the regulations thereunder and disregarding section 416(i)(5)) at any time during the twelve (12) months preceding the Determination Date. This section shall be interpreted and consistently applied by the Committee in accordance with IRC 409A.

4.5Distribution Upon a Change in Control

If timely and properly elected on the Deferral Election Form, a Participant shall be entitled to a Plan Benefit equal to the Participant’s Account if the Participant is serving as an Executive or Director upon a Change in Control prior to Separation from Service.

4.6Benefit Payment Elections and Subsequent Modifications Thereto

Other than for those circumstances that specifically provide to the contrary, a Plan Benefit shall be paid in accordance with the Participant’s most recent valid and timely submitted Distribution Election Form.

A Participant must irrevocably elect the time and form for the payment of his or her Plan Benefit by submitting a valid Distribution Election Form by the later of (i) December 31, 2008 or (ii) the date by which his or her first Deferral Election Form must be submitted to the Committee according to Section 3.1(b) or 3.1(c), as the case may be.

A Participant can elect payment of his or her Plan Benefit upon a Change in Control that occurs prior to Separation from Service by submitting a valid Distribution Election Form by the later of (i) December 31, 2008 or (ii) the date by which his or her first Deferral Election Form must be submitted to the Committee according to Section 3.1(b) or 3.1(c), as the case may be. If a Participant does not elect payment or if a Change in Control does not occur prior to Separation from Service, a Participant’s Plan Benefit shall be payable only upon Separation from Service as provided in Section 5.4.

Using the Distribution Election Form, a Participant can elect the following forms of payment:

(i)A lump sum.

(ii)Substantially equal annual payments for a period as designated by the Participant of five (5), ten (10) or fifteen (15) years. The amount of each annual payment shall be determined by dividing the Participant’s Account on the Determination Date immediately preceding the month of the annual payment by the number of years remaining in the designated installment period.

A Participant may irrevocably elect one form of payment of the entire Plan Benefit upon a Change in Control prior to Separation from Service, and another form of payment for the entire Plan Benefit upon his or her Separation from Service, if so elected on a valid and timely submitted Distribution Election Form. A Participant’s election as to the form of payment upon his or her Separation from Service shall apply to payment in the event of the Participant’s death, as provided in Section 5.2. A Participant’s Plan Benefit shall be paid according to the most recent valid and timely submitted Distribution Election Form submitted to the Committee. In the event that a Participant has not submitted a valid Distribution Election Form, payment shall be made in annual payments for ten (10) years.

{00140563.DOC /4 }    9

A Participant may modify his or her Distribution Election as to the form of payment upon a Change in Control and/or Separation from Service, provided that the following requirements are satisfied:

    (a)    The modified election shall not be effective until twelve (12) months after the date made;

    (b)    For payments beginning as a result of the Participant’s Separation from Service, payments beginning at a fixed time or on a fixed schedule, or payments due as a result of a Change in Control, the first payment due under the modified election must be deferred for a period of at least five years from the date such payment would have been made in the absence of the modified election; and

    (c)    With respect to payments beginning at a fixed time or on a fixed schedule, a Participant must modify his or her Distribution Election at least twelve (12) months prior to the first scheduled payment due under the Plan.

A Participant’s right to receive annual installment payments under this Section 5.6 shall be treated as the right to receive a single payment as provided in Treasury regulation 1.409A-2(b)(2)(iii). A Participant’s Distribution Election may be modified by submitting a new Deferral Election Form to the Committee (or one or more officers designated by the Committee).

Notwithstanding any provision in the immediately preceding paragraph to the contrary, the Committee may authorize changes to the times and forms of payment permitted under this Section 5.6 to the extent consistent with the transition rules and during the transition relief period provided under IRC 409A and the related guidance issued in Treasury regulations and by the Internal Revenue Service.

4.7Withholding Payroll Taxes

The Employer shall withhold from payments made hereunder any taxes required to be withheld from such payments under federal, state or local law. However, a Beneficiary may elect not to have withholding for federal income tax pursuant to Section 3405(a)(2) of the Internal Revenue Code, or any successor provision thereto.

4.8Commencement of Payments

Subject to the provisions of Section 5.4 with respect to a Specified Employee, payment of a Participant’s Plan Benefit shall commence as soon as administratively practicable (determined in the sole discretion of the Committee) but no later than sixty (60) days after (a) the date selected by the Participant in the most recent valid Distribution Election Form or (b) absent such a valid Distribution Election Form, Separation from Service. All payments shall be made as of the first day of the month.

4.9Payment to Guardian

If a Plan Benefit is payable to a minor or a person declared incompetent or to a person incapable of handling the disposition of property, the Committee may direct payment of such Plan Benefit to the guardian, legal representative or person having the care and custody of such minor, incompetent or person. The Committee may require proof of incompetency, minority, incapacity or guardianship as it may deem appropriate prior to distribution of the Plan Benefit. Such distribution shall completely discharge the Committee from all liability with respect to the benefit.

{00140563.DOC /4 }    10

4.10Cashouts

The Committee may, in its discretion, require a mandatory lump sum payment of amounts deferred under this Plan that do not exceed the applicable dollar amount under IRC section 402(g)(1)(B) then in effect, provided that any required exercise of the Committee’s discretion is evidenced in writing no later than the date of such payment, and provided that the payment results in the termination and liquidation of the Participant’s entire interest under the Plan, including all agreements, methods, programs, or other arrangements with respect to which deferrals of compensation are treated as having been deferred under this Plan in accordance with IRC 409A.

ARTICLE VI –BENEFICIARY DESIGNATION

4.1Beneficiary Designation

Each Participant shall have the right, at any time, to designate any person or persons as his or her Beneficiary or Beneficiaries (primary as well as secondary) to whom benefits under this Plan shall be paid in the event of Participant’s death prior to complete distribution of the benefits due under the Plan. Each beneficiary designation shall be in written form prescribed by the Committee and will be effective only when filed with the Committee (or one or more officers designated by the Committee) during the Participant’s lifetime.

4.2Amendments

Any Beneficiary designation may be changed by a Participant without the consent of any designated Beneficiary by the filing of a new Beneficiary designation with the Committee (or one or more officers designated by the Committee). The filing of a new Beneficiary designation form will cancel all Beneficiary designations previously filed. If a Participant’s Compensation is community property, any Beneficiary designation shall be valid or effective only as permitted under applicable law.

4.3No Beneficiary Designation

In the absence of a valid or effective Beneficiary designation, or if all designated Beneficiaries predecease the Participant or die prior to complete distribution of the Participant’s benefits, then the Participant’s designated Beneficiary shall be deemed to be the Participant’s estate.

4.4Effect of Payment

The payment to the deemed Beneficiary shall completely discharge Employer’s obligations under this Plan.

ARTICLE VII –ADMINISTRATION

4.1Committee and Duties

This Plan shall be administered by the Committee. The Committee shall have the authority to make, amend, interpret, and enforce all appropriate rules and regulations for the administration of this Plan and decide or resolve any and all questions including interpretations of this Plan, as may arise in connection with the Plan.

ARTICLE IX –AMENDMENT AND TERMINATION OF PLAN

4.1Amendment

The Board may at any time amend the Plan in whole or in part, provided, however, that no amendment shall be effective to decrease or restrict the amount accrued to the date of Amendment in any Account. For Participants who entered the Plan and began participating prior to January 1, 2014, no amendment shall change the Interest Rate credited to amounts already held in an Account under the Plan, thirty (30) days advance written notice of any change in the Interest Rate shall be given to each Participant, and any deferral after the effective date of the change shall be held in a separate Account which shall be credited with the new Interest Rate.

4.2Right to Terminate

The Board may at any time partially or completely terminate the Plan if, in its judgment, the tax, accounting, or other effects of the continuance of the Plan, or potential payments thereunder would not be in the best interests of the Employer.

(a)Partial Termination. The Board may partially terminate the Plan by instructing the Committee not to accept any additional Deferrals. In the event of such a Partial Termination, the Plan shall continue to operate and be effective with regard to Deferral Elections entered into prior to the effective date of such Partial Termination and all Participants’ Plan Benefits shall be paid at the time and in the manner otherwise specified in this Plan.

(b)Complete Termination. Subject to the provisions of IRC 409A and Treasury regulation 1.409A-3(j)(4)(ix), the Board may completely terminate the Plan by instructing the Committee not to accept any additional Deferral Elections, and by terminating all ongoing Deferral Elections. In the event of Complete Termination, Participants shall cease participation in the Plan and shall not accrue any further benefits. Except as provided herein, Plan Benefits shall be paid at the time and in the manner otherwise specified in this Plan. Notwithstanding the preceding sentence, the Employer shall pay out to each Participant (or Participant’s Beneficiary) his or her Account in a single lump sum as if that Participant had a Separation from Service on the first day of the second twelve (12) month period that began with the date of the Complete Termination provided all of the following requirements are satisfied:

(i)The Complete Termination and liquidation of the Plan do not occur proximate to a downturn in the financial health of the Employer;

(ii)The Employer terminates all arrangements sponsored by the Employer that would be aggregated with any terminated arrangement under Treasury regulations section 1.409A-1(c) if a Participant participated in all of the arrangements;

{00140563.DOC /4 }    13

(iii)No payments are made within twelve (12) months of the termination, other than payments that would have been payable if the termination had not occurred;

(iv)All payments are made within twenty-four (24) months of the termination; and

(v)The Employer does not adopt a new deferred compensation plan that would be aggregated with any terminated arrangement under Treasury regulations section 1.409A-1(c), if a Participant participated in both arrangements, within three (3) years following the date the Employer takes all necessary action to irrevocably terminate and liquidate the Plan.

Notwithstanding any provision in the Plan to the contrary, interest earned on the unpaid balance in each Participant’s Account shall be the Interest Rate in effect on the Determination Date immediately preceding the effective date of the Complete Termination.

ARTICLE X –MISCELLANEOUS

4.1Unfunded Plan

This Plan is intended to be an unfunded plan maintained primarily to provide deferred compensation benefits for a select group of “management or highly compensated employees” within the meaning of Sections 201, 301, and 401 of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), and therefore to be exempt from the provisions of ERISA Title I, Parts 2, 3, and 4.

4.2Unsecured General Creditor

Participants and their Beneficiaries, heirs, successors, and assigns shall have no legal or equitable rights, interest or claims in any property or assets of the Employer, nor shall they be Beneficiaries of, or have any rights, claims or interests in any life insurance policies, annuity contracts, or the proceeds therefrom owned or which may be acquired by the Employer. Except as may be provided in Section 10.3, such policies, annuity contracts or other assets of the Employer shall not be held under any trust for the benefit of Participants, their Beneficiaries, heirs, successors or assigns, or held in any way as collateral security for the fulfilling of the obligations of the Employer under this Plan. Any and all of the Employer’s assets and policies shall be, and remain, the general, unpledged, unrestricted assets of the Employer. The Employer’s obligation under the Plan shall be that of an unfunded and unsecured promise to pay money in the future.

4.3Trust Fund

The Employer shall be responsible for the payment of all benefits provided under the Plan. At its discretion, the Employer may establish one (1) or more trusts, with such trustees as the Board may approve, for the purpose of providing for the payment of such benefits. Such trust or trusts may be irrevocable, but the assets thereof shall be subject to the claims of the Employer’s creditors. To the extent any benefits provided under the Plan are actually paid from any such trust, the Employer shall have no further obligation with respect thereto, but to the extent not so paid, such benefits shall remain the obligation of, and shall be paid by, the Employer.

{00140563.DOC /4 }    14

4.4Nonassignability

Neither a Participant nor any other person shall have any right to commute, sell, assign, transfer, pledge, anticipate, mortgage or otherwise encumber, transfer, hypothecate or convey in advance of actual receipt the amounts, if any, payable hereunder, or any part thereof, which are, and all rights to which are, expressly declared to be unassignable and nontransferable. No part of the amounts payable shall, prior to actual payment, be subject to seizure or sequestration for the payment of any debts, judgments, alimony or separate maintenance owed by a Participant or any other person, nor be transferable by operation of law in the event of a Participant’s or any other person’s bankruptcy or insolvency.

4.5Not a Contract of Employment

The terms and conditions of this Plan shall not be deemed to constitute a contract of employment between the Employer and the Participant. The Participant (and his or her Beneficiaries) shall have no rights against the Employer except as may otherwise be specifically provided herein. Moreover, nothing in this Plan shall be deemed to give a Participant the right to be retained in the service of the Employer or to interfere with the right of the Employer to discipline or discharge him at any time.

4.6Protective Provisions

A Participant will cooperate with the Employer by furnishing any and all information requested by the Employer, in order to facilitate the payment of benefits hereunder, and by taking such physical examinations as the Employer may deem necessary and taking such other actions as may be requested by the Employer.

4.7Terms

Whenever any words are used herein in the masculine, they shall be construed as though they were used in the feminine in all cases where they would so apply; and wherever any words are used herein in the singular or in the plural, they shall be construed as though they were used in the plural or the singular, as the case may be, in all cases where they would so apply.

4.8Captions

The captions of the articles, sections, and paragraphs of this Plan are for convenience only and shall not control or affect the meaning or construction of any of its provisions.

4.9Governing Law

The provisions of this Plan shall be construed, interpreted, and governed in all respects in accordance with applicable federal law and, to the extent not preempted by such federal law, in accordance with the laws of the State of California.

{00140563.DOC /4 }    15

4.11Notice

Any notice or filing required or permitted to be given to the Committee under the Plan shall be sufficient in writing and hand delivered, or sent by registered or certified mail, to any member of the Committee or Employer’s statutory agent. Such notice shall be deemed given as of the date of delivery or, if such delivery is made by mail, as of the date shown on the postmark on the receipt for registration or certification.

4.12Successors

The provisions of this Plan shall bind and inure to the benefit of the Employer and its successors and assigns. The term successors as used herein shall include any corporate or other business entity which shall, whether by merger, consolidation, purchase or otherwise acquire all or substantially all of the business and assets of TriCo Bancshares, and successors of any such corporation or other business entity.

2022 NonExec RSU Grant Notice for 2019 Plan

Trico Bancshares

2019 EQUITY INCENTIVE PLAN

RESTRICTED STOCK UNIT AWARD AGREEMENT

Pursuant to the Restricted Stock Unit Award Grant Notice (“Grant Notice”) and this Restricted Stock Unit Award Agreement (“Award Agreement”), Trico Bancshares (the “Company”) has awarded you a Restricted Stock Unit Award under its 2019 Equity Incentive Plan, (the “Plan”) for the number of RSUs specified in the Grant Notice (collectively, the “Award”). Except where indicated otherwise, defined terms not explicitly defined in this Award Agreement but defined in the Plan or Grant Notice shall have the same definitions as in the Plan or Grant Notice, You hereby understand that the shares of Common Stock issued with respect to the Award is subject to minimum holding requirements described in Section 10(f) of the Plan.

The details of your Award are as follows:

1.Number of Restricted Stock Units and Shares of Common Stock. The number of RSUs subject to your Award is set forth in the Grant Notice. Each RSU shall represent the right to receive one (1) share of Common Stock. The number of RSUs will increase by any dividend equivalents, as described in Section 3 below. The number of RSUs subject to your Award and the number of shares of Common Stock deliverable with respect to such RSUs may be adjusted from time to time for capitalization adjustments as described in Section 11(a) of the Plan.

2.Vesting. The RSUs shall vest, if at all, as provided in the vesting schedule set forth in your Grant Notice; provided, however, that vesting shall cease upon the termination of your Continuous Service for any reason. In the event that your service with the Company terminates for any reason, with or without cause, you shall forfeit and the Company shall automatically reacquire all RSUs which are not, as of the time of such termination, vested Units, and you shall not be entitled to any payment therefor.

Death/Disability. If you die or become Permanently Disabled (as defined below) while you are eligible to vest in RSUs under this Award, the RSUs will immediately vest and will be distributed in shares of Common Stock (after applicable tax withholding, if any) to your designated beneficiary on file with the Company’s stock administration department or Human Resources, or if no beneficiary has been designated or survives you or if beneficiary designation is not recognized by local legislation, then to your estate (in the case of death) or to you (in the case of Permanent Disability). Any shares will be distributed no later than the end of the calendar year immediately following the calendar year which contains your date of death or Permanent Disability; however, with respect to shares issued due to death, our administrative practice is to register such shares in the name of your beneficiary or estate within 60 days of the Company’s receipt of any required documentation.

“Permanently Disabled” means your “permanent disability” as such term is defined in the long-term disability insurance provided by the Company, or if such insurance is not provided by Company, the term shall mean that Participant has been deemed by a medical care provider to indefinitely be unable to perform the essential functions of Participant’s position with or without reasonable accommodation, and you satisfied the Release/Certification Requirements set forth below.

Release/Certification. You shall meet the “Release/Certification Requirements,” if: (i) within 55 days following your termination of Continuous Service due to Permanent Disability, you execute and deliver a general release of claims in favor of the Company, having such form

2022 NonEx RSU Grant Notice for 2019 Plan

    2

and terms as the Company shall specify, and such release becomes irrevocable, and (ii) in all cases, you have complied with all other terms of the Award Agreement.

Except as otherwise set forth in this Section 2 or as determined by the Committee under the terms of Section 11 of the Plan, in the event of a Change in Control, no acceleration of vesting shall occur with respect to the Units granted in this Award.

3.Dividends. If the Company pays dividends with respect to the Common Stock (the date of any such payment is a “Dividend Date”), then Dividend equivalents shall then be credited to any then outstanding RSU. The amount of such dividend equivalent credit will be equal to the dollar value of dividends paid on an actual share of Common Stock on the Dividend Date, multiplied by the number of outstanding RSUs held by you pursuant to this Award as of the Dividend Date. This aggregate dollar amount will then be divided by the Fair Market Value on the Dividend Date of a share of Common Stock, and the resulting quotient shall be the number of additional RSUs “Additional RSUs” that will be credited to this Award. Such Additional RSUs will be subject to the Plan and the same vesting (on a pro-rata basis based on each vesting tranche of RSUs outstanding hereunder on the Dividend Date), forfeiture restrictions, restrictions on transferability, and settlement provisions as apply to the RSUs that are the subject of this Award and for avoidance of doubt Additional RSUs will also be eligible to accrue future dividend equivalents.

4.Rights as a Shareholder. You shall have no rights as a shareholder with respect to any shares of Common Stock which may be issued in settlement of this Award until the date of the issuance of such share of Common Stock under the terms of this Award Agreement (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company). No adjustment shall be made for dividends, Dividend Equivalents, distributions or other rights for which the record date is prior to the date such certificate is issued, except as provided in Section 1.

5.Payment. Subject to Section 11 below, you will not be required to make any payment to the Company with respect to your receipt of the Award, vesting of the RSUs, or the delivery of the shares of Common Stock subject to the RSUs.

6.Delivery of Shares. Subject to Sections 7 and 11 below, the Company will issue you one share of Common Stock for each RSU which vests under this Award Agreement, on the applicable vesting date or as soon as practicable thereafter, but not later than thirty (30) days from the vesting date (the actual date of such issuance during such period shall be solely determined by the Company). The form of delivery (e.g., a stock certificate or electronic entry evidencing such shares of Common Stock) shall be determined by the Company. You hereby authorize the Company, in its sole discretion, to deposit for your benefit with a Company-designated brokerage firm or, at the Company’s discretion, any other broker with which you have an account relationship of which the Company has notice any or all shares of Common Stock acquired by you pursuant to the settlement of the Award. Except as provided by the preceding sentence, a certificate for the shares of Common Stock as to which the Award is settled shall be registered in your name, or, if applicable, in the names of your heirs.

7.Restrictions on Grant of the Award and Issuance of Shares. The grant of the Award and issuance of shares of Common Stock upon settlement of the Award shall be subject to compliance with all applicable requirements of U.S. federal or state law with respect to such securities. No shares of Common Stock may be issued hereunder if the issuance of such shares of Common Stock would constitute a violation of any applicable U.S. federal or state securities laws or other laws or regulations or the requirements of any stock exchange or market system upon which the Common Stock may then be listed. The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company’s legal

2022 NonEx RSU Grant Notice for 2019 Plan

    3

counsel to be necessary to the lawful issuance of any shares of Common Stock subject to the Award shall relieve the Company of any liability in respect of the failure to issue such shares of Common Stock as to which such requisite authority shall not have been obtained. As a condition to the settlement of the Award, the Company may require you to satisfy any qualifications that may be necessary or appropriate, to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect thereto as may be requested by the Company. Further, regardless of whether the transfer or issuance of the shares of Common Stock to be issued pursuant to the Units has been registered under the Securities Act or has been registered or qualified under the securities laws of any State, the Company may impose additional restrictions upon the sale, pledge, or other transfer of the shares of Common Stock (including the placement of appropriate legends on stock certificates and the issuance of stop-transfer instructions to the Company’s transfer agent) if, in the judgment of the Company and the Company’s counsel, such restrictions are necessary in order to achieve compliance with the provisions of the Securities Act, the securities laws of any State, or any other law.

8.Transfer Restrictions. Prior to the time that the shares of Common Stock subject to your Award have been delivered to you, you may not transfer, pledge, sell or otherwise dispose of such shares of Common Stock or of the RSUs. For example, you may not use shares of Common Stock that may be issued in respect of your RSUs as security for a loan, nor may you transfer, pledge, sell or otherwise dispose of such shares of Common Stock. This restriction on transfer will lapse upon delivery to you of shares of Common Stock in respect of your vested RSUs. Your Award is not transferable, except by will or by the laws of descent and distribution. Notwithstanding the foregoing, by delivering written notice to the Company, in a form satisfactory to the Company, you may designate a third party who, in the event of your death, shall thereafter be entitled to receive any distribution of shares of Common Stock in respect of vested RSUs pursuant to this Agreement.

9.Award Not a Service Contract. Your Award is not an employment or service contract, and nothing in your Award shall be deemed to create in any way whatsoever any obligation on your part to continue in the service of the Company or any Affiliate, or on the part of the Company or any Affiliate to continue such service. In addition, nothing in your Award shall obligate the Company or any Affiliate, their respective shareholders, boards of directors or employees to continue any relationship that you might have as an Employee or Consultant of the Company or any Affiliate.

10.Unsecured Obligation. Your Award is unfunded, and even as a holder of vested RSUs, you shall be considered an unsecured creditor of the Company with respect to the Company’s obligation, if any, to issue shares of Common Stock pursuant to this Agreement. Nothing contained in this Award Agreement, and no action taken pursuant to its provisions, shall create or be construed to create a trust of any kind or a fiduciary relationship between you and the Company or any other person.

11.Withholding of Taxes. At the time the Grant Notice is executed, or at any time thereafter as requested by the Company, you hereby authorize withholding from payroll and any other amounts payable to you, and otherwise agree to make adequate provision for, any sums required to satisfy the U.S. federal, state, and local taxes required by law to be withheld with respect to any taxable event arising as a result of your participation in the Plan (referred to herein as “Tax-Related Items”). The Company or any Affiliate, as appropriate, shall have the authority and the right to deduct or withhold, or require you to remit an amount sufficient to satisfy applicable Tax-Related Items or to take such other action as may be reasonably necessary to satisfy such Tax-Related Items. In this regard, you authorize the Company and any Affiliate, or their respective agents, at their discretion, to satisfy the obligations with regard to all Tax-Related Items by one or a combination of the following:

(a)withholding from your wages or other cash compensation paid to you; or

(c)withholding in shares of Common Stock to be issued upon vesting and settlement of the Units; or

14.Headings. The headings of the Sections in this Agreement are inserted for convenience only and shall not be deemed to constitute a part of this Agreement or to affect the meaning of this Award Agreement.

15.Severability. If all or any part of this Agreement or the Plan is declared by any court or governmental authority to be unlawful or invalid, such unlawfulness or invalidity shall not invalidate any portion of this Agreement or the Plan not declared to be unlawful or invalid. Any Section of this Agreement (or part of such a Section) so declared to be unlawful or invalid shall, if possible, be construed in a manner which will give effect to the terms of such Section or part of a Section to the fullest extent possible while remaining lawful and valid.

16.Compliance with Code Section 409A.

(a)It is intended that the RSUs granted hereunder be exempt from or comply with the requirements of Code Section 409A, so that none of the RSUs, or the resulting shares of Common Stock or compensation, if any, shall be subject to the additional tax imposed by Section 409A. The vesting and settlement of such RSUs are intended to qualify for the “short-term deferral” exemption from Code Section 409A. Each installment of RSUs that vests is intended to constitute a “separate payment” for purposes of Treasury Regulation Section 1.409A-2(b)(2). As such, each eligible vested RSU shall be settled, per the terms of the Plan, the Grant Notice and this Award Agreement, within the short-term deferral period, as defined in Code Section 409A, the applicable Treasury Regulations and related guidance issued thereunder. Notwithstanding any other provision of the Plan, this Award Agreement, the Grant Notice or the Plan:

(i)The Plan, this Agreement and the Grant Notice shall be interpreted in accordance with, and incorporate the terms and conditions required by, Code Section 409A and any Department of Treasury regulations and other applicable guidance issued thereunder (including any regulations or guidance that may be issued after the date hereof), and any ambiguities herein shall be interpreted to so comply.

(ii)The Company reserves the right, to the extent the Company deems necessary or advisable in its sole discretion, to unilaterally amend or modify the Plan and/or this Award Agreement to ensure that the RSUs qualify for exemption from, comply with or otherwise avoid the imposition of any additional tax or income recognition under Code Section 409A; provided, however, that the Company makes no representations that the RSUs will be exempt from Code Section 409A and makes no undertaking to preclude Code Section 409A from applying to the RSUs.

(b)Separation from Service; Required Delay in Payment to Specified Employee. Notwithstanding anything set forth herein to the contrary, no amount payable pursuant to this Agreement on account of your termination of Service which constitutes a “deferral of compensation” within the meaning of Code Section 409A shall be paid unless and until you have incurred a “separation from service” within the meaning of Code Section 409A. Furthermore, to the extent that you are a “Specified Employee” within the meaning of Code Section 409A as of the date of your separation from service, no amount that constitutes a deferral of compensation which is payable on account of the your separation from service that would result in the imposition of additional tax under Code Section 409A if issued to you on or within the six (6) month period following your termination of an employment shall be paid to you before the date which is the first day of the seventh month after the date of your separation from service or, if earlier, ten (10) days following the date of your death following such separation from service. All such amounts that would, but for this Section, become payable prior to a delayed payment date will be accumulated and paid on the delayed payment date.

The Company hereby awards to the Participant the Target Number of Units set forth in the Grant Notice, which, depending on the extent to which a Performance Goal (as described by Plan) is attained during the Performance Period, may result in the Participant earning as little as zero (0) Units or as many as the Maximum Number of Units. Subject to the terms of this Award Agreement and the Plan, each Unit, to the extent it is earned and becomes a Vested Unit, represents a right to receive on the Settlement Date one (1) share of Stock or, at the discretion of the Committee, the Fair Market Value thereof in cash. Unless and until a Unit has vested and become a Vested Unit as set forth in the Grant Notice, the Participant will have no right to settlement of such Units (including any rights with respect dividends payable with respect to the underlying shares of Common Stock). Prior to settlement of any earned and vested Units, such Units will represent an unfunded and unsecured obligation of the Company.

2.Performance Measurement.

2.1Level of Performance Measure Attained. As soon as practicable following completion of the Performance Period, but in any event no later than the Vesting Date, the Committee shall certify in writing the level of attainment of the Performance Measure during the Performance Period, the resulting Relative Return Factor and the number of Units which have become Vested Units.

2.2Components of Performance Measure. The components of Performance Measure shall be determined for the Performance Period in accordance with the following:

(a)“Company Total Shareholder Return” means the percentage point increase or decrease in (i) the Average Per Share Closing Price for the 30 trading day period ending on the last day of the Performance Period over (ii) the Average Per Share Closing Price for the 30 trading day period ending on the first day of the Performance Period.

(b)“Average Per Share Closing Price” means the average of the daily closing prices per share of Common Stock as reported on the Nasdaq Stock Market (or such other market on which shares of Common Stock are traded)for all trading days falling within an applicable 30 trading day period described in (a) above. The Average Per Share Closing Price shall be adjusted in each case to reflect an assumed reinvestment, as of the of applicable ex-dividend date, of all cash dividends and other cash distributions (excluding cash distributions resulting from share repurchases or redemptions by the Company) paid to shareholders during

3.3Vesting Upon Involuntary Termination Following a Change in Control.

3.4Vesting Upon Death/Disability. If you die or become Permanently Disabled (as defined below) while you are eligible to vest in PSUs under this Award, the PSUs will immediately vest pro rata in a similar fashion as set forth in Section 7 and will be distributed in shares of Common Stock (after applicable tax withholding, if any) to your designated beneficiary on file with the Company’s stock administration department or Human Resources, or if no beneficiary has been designated or survives you or if beneficiary designation is not recognized by local legislation, then to your estate (in the case of death) or to you (in the case of Permanent Disability). Any shares will be distributed no later than the end of the calendar year immediately following the calendar year which contains your date of death or Permanent Disability; however, with respect to shares issued due to death, our administrative practice is to register such shares in the name of your beneficiary or estate within 60 days of the Company’s receipt of any required documentation.

“Permanently Disabled” means your “permanent disability” as such term is defined in the long-term disability insurance provided by the Company, or if such insurance is not provided by Company, the term shall mean that Participant has been deemed by a medical care provider to indefinitely be unable to perform the essential functions of Participant’s position with or without reasonable accommodation, and you satisfied the Release/Certification Requirements set forth below.

Release/Certification.

The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company’s legal counsel to be necessary to the lawful issuance of any shares of Common Stock subject to the Award shall relieve the Company of any liability in respect of the failure to issue such shares of Common Stock as to which such requisite authority shall not have been obtained. As a condition to the settlement of the Award, the Company may require the Participant to satisfy any qualifications that may be necessary or appropriate, to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect thereto as may be requested by the Company. Further, regardless of whether the transfer or issuance of the shares of Common Stock to be issued pursuant to the Units has been registered under the Securities Act or has been registered or qualified under the securities laws of any State, the Company may impose additional restrictions upon the sale, pledge, or other transfer of the shares of Common Stock (including the placement of appropriate legends on stock certificates and the issuance of stop-transfer instructions to the Company’s transfer agent) if, in the judgment of the Company and the Company’s counsel, such restrictions are necessary in order to achieve compliance with the provisions of the Securities Act, the securities laws of any State, or any other law.

(i)The Company Total Shareholder Return shall be determined as provided by Section 2.2, except that the Average Per Share Closing Price for the thirty (30) trading day period ending on the last day of the Adjusted Performance Period shall be replaced with the price per share of Common Stock to be paid to the holder thereof in accordance with the definitive agreement governing the transaction constituting the Change in Control (or, in the absence of such agreement, the closing price per share of Common Stock as reported on the Nasdaq Stock Marketfor the last trading day of the Adjusted Performance Period), adjusted to reflect an assumed reinvestment, as of the applicable ex-dividend date, of all cash dividends and other cash distributions (excluding cash distributions resulting from share repurchases or redemptions by the Company) paid to shareholders during the Adjusted Performance Period, as illustrated in Section 2.2.

(ii)The Benchmark Index Total Return shall be determined as provided by Section 2.2, except that for the purposes of clause (a) thereof, the Average Closing Index Value shall be determined for the 30 trading day period ending on the last day of the Adjusted Performance Period.

(b)Vested Units. As of the last day of the Adjusted Performance Period and provided that the Participant has not Termination of Continuous Service prior to such date, a portion of the Units determined in accordance with Section 7.1(a) shall become Vested Units (the “Accelerated Units”), with such portion determined by multiplying the total number of Units by a fraction, the numerator of which equals the number of days contained in the Adjusted Performance Period and the denominator of which equals the number of days contained in the original Performance Period determined without regard to this Section. The Accelerated Units shall be settled in accordance Section 4 immediately prior to the consummation of the Change in Control.

7.2Involuntary Termination Following Change in Control. If Section 7.1 does not apply, in the event that upon or within twelve (12) months following the effective date of the Change in Control (but no earlier than the twelve month anniversary of the Grant Date), the Participant experiences an Involuntary Termination, the Units determined in accordance with Section 7.1(a) (as if Section 7.1 applied) shall be deemed Vested Units effective as of the date of the Participant’s Involuntary Termination and shall be settled in accordance with Section 4, treating the date of the Participant’s Termination of Continuous Service as the Vesting Date, provided that payment for each Vested Unit shall be made in the amount and in the form of the consideration (whether stock, cash, other securities or property or a combination thereof) to which a holder of a share of Common Stock on the effective date of the Change in Control was entitled (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding shares of Common Stock).

7.3Internal Revenue Code Section 280G. Notwithstanding any provision of this Award Agreement to the contrary, in the event that it would be more likely than not that all or a portion of any benefit payment under this Award Agreement, alone or together with any other compensation or benefit payable to Participant, will be a non-deductible expense to the Company by reason of Code Section 280G, the Company shall reduce, but not less that zero, the benefits payable under this Award Agreement or the Plan as necessary to avoid the application of Section 280G.

The Participant shall be notified of such adjustments and such adjustments shall be binding upon the Company and the Participant.

9.No Entitlement or claims for compensation.

10.Rights as a Shareholder.

The Participant shall have no rights as a shareholder with respect to any shares of Common Stock which may be issued in settlement of this Award until the date of the issuance of such share of Common Stock under this Award Agreement (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company). No adjustment shall be made for dividends, Dividend Equivalents, distributions or other rights for which the record date is prior to the date such certificate is issued, except as provided in Section 8.

(a)Compliance with Code Section 409A. It is intended that the Performance Share Units granted hereunder be exempt from or comply with the requirements of

2022 NonExec PSU Grant Notice for 2019 Plan -9-

Code Section 409A, so that none of the Units, or the resulting shares of Common Stock or compensation, if any, shall be subject to the additional tax imposed by Section 409A. The vesting and settlement of such Units are intended to qualify for the “short-term deferral” exemption from Code Section 409A. Each installment of Units that vests is intended to constitute a “separate payment” for purposes of Treasury Regulation Section 1.409A-2(b)(2). As such, each eligible Vested Unit shall be settled, per the terms of the Plan, the Grant Notice and this Award Agreement, within the short-term deferral period, as defined in Code Section 409A, the applicable Treasury Regulations and related guidance issued thereunder. Notwithstanding any other provision of the Plan, this Award Agreement, the Grant Notice or the Plan:

(i)The Plan, this Award Agreement and the Grant Notice shall be interpreted in accordance with, and incorporate the terms and conditions required by, Code Section 409A and any Department of Treasury regulations and other applicable guidance issued thereunder (including any regulations or guidance that may be issued after the date hereof), and any ambiguities herein shall be interpreted to so comply.

(ii) The Company reserves the right, to the extent the Company deems necessary or advisable in its sole discretion, to unilaterally amend or modify the Plan and/or this Award Agreement to ensure that the Units qualify for exemption from, comply with or otherwise avoid the imposition of any additional tax or income recognition under Code Section 409A; provided, however, that the Company makes no representations that the Units will be exempt from Code Section 409A and makes no undertaking to preclude Code Section 409A from applying to the Units.

(b)Separation from Service; Required Delay in Payment to Specified Employee. Notwithstanding anything set forth herein to the contrary, no amount payable pursuant to this Award Agreement on account of the Participant’s Termination of Continuous Service which constitutes a “deferral of compensation” within the meaning of Code Section 409A shall be paid unless and until the Participant has incurred a “separation from service” within the meaning of Code Section 409A. Furthermore, to the extent that the Participant is a “Specified Employee” within the meaning of Code Section 409A as of the date of the Participant’s separation from service, no amount that constitutes a deferral of compensation which is payable on account of the Participant’s separation from service that would result in the imposition of additional tax under Code Section 409A if issued to Participant on or within the six (6) month period following Participant’s separation from service shall be paid to the Participant before the date (the “Delayed Payment Date”) which is the first day of the seventh month after the date of the Participant’s separation from service or, if earlier, ten (10) days following the date of the Participant’s death following such separation from service. All such amounts that would, but for this Section, become payable prior to the Delayed Payment Date will be accumulated and paid on the Delayed Payment Date.

11.10Restrictions on Contracts and Payments for Insured Depository Institutions in Troubled Status. The parties acknowledge and agree that while the restrictions contained in the Federal Deposit Insurance Act, Section 18(k) [12 U.S.C. §1828(k)], relating to contracts for and payment of executive compensation and benefits by insured depository institutions in “troubled” condition, do not currently apply to the Company or the Participant, such provisions could apply in the future. In the event that any such restrictions or any contractual arrangement with or required by a regulatory authority require the Company to seek or demand repayment or return of any payments made to the Participant under this Award Agreement and the Plan for any reason, the Participant agrees to repay to the Company the aggregate amount of such payments no later than thirty (30) days following the Participant’s receipt of a written notice from the Company indicating that payments received by the Participant under this Award Agreement and the Plan are subject to recapture or clawback.

2022 NonExec PSU Grant Notice for 2019 Plan -10-

11.11Administration. The Committee shall have the power to interpret the Plan and this Award Agreement and to adopt such rules for the administration, interpretation and application of the Plan as are consistent therewith and to interpret, amend or revoke any such rules. All actions taken and all interpretations and determinations made by the Committee or the Board in good faith shall be final and binding upon the Participant, the Company and all other interested persons. No member of the Committee or the Board shall be personally liable for any action, determination or interpretation made in good faith with respect to the Plan, this Award Agreement or the Units.

11.12Counterparts. The Grant Notice may be executed in counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

11.13Severability. If any provision of this Award Agreement is held to be unenforceable for any reason, it shall be adjusted rather than voided, if possible, in order to achieve the intent of the parties to the extent possible. In any event, all other provisions of this Award Agreement shall be deemed valid and enforceable to the full extent possible.

Summary of Significant Accounting Policies

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 and retail banking business in 32 California counties. 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 obtained through acquisition.

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. For financial reporting purposes, the Company’s investments in the Capital Trusts of $1,757,000 are accounted for under the equity method and, accordingly, are included in other assets on the consolidated balance sheets. The subordinated debentures issued and guaranteed by the Company and held by the Capital Trusts are reflected as debt on the Company’s consolidated balance sheets.

Use of Estimates in the Preparation of Financial Statements

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

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.

Business Combinations

The Company accounts for acquisitions of businesses using the acquisition method of accounting. Under the acquisition method, assets acquired and liabilities assumed are recorded at their estimated fair values at the date of acquisition. Management utilizes various valuation techniques including discounted cash flow analyses to determine these fair values. Any excess of the purchase price over amounts allocated to the acquired assets, including identifiable intangible assets, and liabilities assumed is recorded as goodwill.

Cash and Cash Equivalents

For purposes of the consolidated statements of cash flows, cash and cash equivalents include cash on hand, amounts due from banks, and federal funds sold. Net cash flows are reported for loan and deposit transactions and other borrowings.

Non-Marketable and Other Equity Securities

Non-marketable and other equity securities include qualified public welfare investments and venture capital/private equity funds. Our accounting for investments in non-marketable and other equity securities depends on several factors, including the level of ownership, power to control and the legal structure of the subsidiary making the investment. We base our accounting for such securities on: (i) fair value accounting, (ii) measurement alternative for other investments without a readily determinable fair value, and (iii) equity method accounting. During the twelve months ended December 31, 2022 and 2021, the Company recognized net unrealized gains of $35,000 and $718,000, respectively, in the consolidated statements of net income related to changes in the fair value of non-marketable and other equity securities.

Debt Securities

The Company classifies its debt securities into one of three categories: trading, available for sale or held to maturity. Trading securities are bought and held principally for the purpose of selling in the near term and changes in the value of these securities are recorded through earnings. Held to maturity securities are those securities which the Company has the ability and intent to hold until maturity. These securities are carried at cost adjusted for amortization of premium and accretion of discount, computed by the effective interest method over their contractual lives. All other securities not included in trading or held to maturity are classified as available for sale. AFS securities are recorded at fair value. Unrealized gains and losses, net of the related tax effect, on available for sale securities are reported as a separate component of other accumulated comprehensive income in shareholders’ equity until realized. Discounts are amortized or accreted over the expected life of the related investment security as an adjustment to yield using the effective interest method. Premiums on callable debt securities are generally amortized to the earliest call date of the security with the exception of mortgage backed securities, where estimated prepayments, if any, are considered. Dividend and interest income are recognized when earned. Realized gains and losses are derived from the amortized cost of the security sold. The Company did not have any debt securities classified as trading during the three year period ended December 31, 2022.

The Company has made a policy election to exclude accrued interest from the amortized cost basis of debt securities and report accrued interest separately in the consolidated balance sheets. A debt security is placed on nonaccrual status at the time any principal or interest payments become more than 90 days delinquent or if full collection of interest or principal becomes uncertain. Accrued interest for a security placed on nonaccrual is reversed against interest income. There was no accrued interest related to debt securities reversed against interest income for the years ended December 31, 2022, 2021 and 2020.

The Company evaluates available for sale debt securities in an unrealized loss position to determine whether the decline in the fair value below the amortized cost basis (impairment) is due to credit-related factors or noncredit-related factors. Any impairment that is not credit related is recognized in other comprehensive income, net of applicable taxes. Credit-related impairment is recognized as an allowance for credit losses on the balance sheet, limited to the amount by which the amortized cost basis exceeds the fair value, with a corresponding adjustment to earnings. Both the allowance for credit losses and the adjustment to net income may be reversed if conditions change. However, if the Company intends to sell an impaired available for sale debt security or more likely than not will be required to sell such a security before recovering its amortized cost basis, the entire impairment amount is recognized in earnings with a corresponding adjustment to the security's amortized cost basis. In evaluating available for sale debt securities in unrealized loss positions for impairment and the criteria regarding its intent or requirement to sell such securities, the Company considers the extent to which fair value is less than amortized cost, whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred, and the results of reviews of the issuers' financial condition, among other factors. Changes in the allowance for credit losses are recorded as provision for (or reversal of) credit loss expense. Losses are charged against the ACL when management believes the uncollectability of an available for sale debt security is confirmed or when either of the criteria regarding intent or requirement to sell is met. No security credit losses were recognized during the years ended December 31, 2022, 2021 or 2020.

For HTM debt securities, the Company measures expected credit losses on held-to-maturity debt securities on a collective basis by major security type, then further disaggregated by sector and bond rating. Accrued interest receivable on held-to-maturity (HTM) debt securities is excluded from the estimate of credit losses. The estimate of expected credit losses considers historical credit loss information that is adjusted for current condition and reasonable and supportable forecasts based on current and expected changes in credit ratings and default rates. Based on the implied guarantees of the U. S. Government or its agencies related to certain of these HTM investment securities, and the absence of any historical or expected losses, substantially all qualify for a zero loss assumption. Management has separately evaluated its HTM investment securities from obligations of state and political subdivisions utilizing the historical loss data represented by similar securities over a period of time spanning nearly 50 years. As a result of this evaluation, management determined that the expected credit losses associated with these securities is not significant for financial reporting purposes and therefore, no allowance for credit losses has been recognized during the years ended December 31, 2022, 2021 or 2020.

Restricted Equity Securities

Restricted equity securities represent the Company’s investment in the stock of the Federal Home Loan Bank of San Francisco (“FHLB”) and are carried at par value, which reasonably approximates its fair value. While technically these are considered equity securities, there is no market for the FHLB stock. Therefore, the shares are considered as restricted investment securities. Management periodically evaluates FHLB stock for other-than-temporary impairment. Management’s determination of whether these investments are impaired is based on its assessment of the ultimate recoverability of cost rather than by recognizing temporary declines in value. The determination of whether a decline affects the ultimate recoverability of cost is influenced by criteria such as (1) the significance of any decline in net assets of the FHLB as compared to the capital stock amount for the FHLB and the length of time this situation has persisted, (2) commitments by the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLB, (3) the impact of legislative and regulatory changes on institutions and, accordingly, the customer base of the FHLB, and (4) the liquidity position of the FHLB.

As a member of the FHLB system, the Bank is required to maintain a minimum level of investment in FHLB stock based on specific percentages of its outstanding mortgages, total assets, or FHLB advances. The Bank may request redemption at par value of any stock in excess of the minimum required investment. Stock redemptions are at the discretion of the FHLB. Both cash and stock dividends are reported as income when received.

Loans Held for Sale

Loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or fair value, as determined by aggregate outstanding commitments from investors of current investor yield requirements. Net unrealized losses are recognized through a valuation allowance by charges to non-interest income.

Mortgage loans held for sale are generally sold with the mortgage servicing rights retained by the Company. Gains or losses on the sale of loans that are held for sale are recognized at the time of the sale and determined by the difference between net sale proceeds and the net book value of the loans less the estimated fair value of any retained mortgage servicing rights.

Loans

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

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

Allowance for Credit Losses - Loans

The Company measures credit losses under ASU 2016-03 Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which replaced the incurred loss methodology, and is referred to as the current expected credit loss (CECL) methodology. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized costs, including loan receivables and held-to-maturity debt securities.

The allowance for credit losses (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 and U.S. gross domestic product.

A loan is considered to be collateral dependent when repayment is expected to be provided substantially through the operation or sale of the collateral. The ACL on collateral dependent loans is measured using the fair value of the underlying collateral, adjusted for costs to sell when applicable, less the amortized cost basis of the financial asset. If the value of underlying collateral is determined to be less than the recorded amount of the loan, a charge-off will be taken. Loans for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulties, is considered to be a troubled debt restructuring (TDR). The ACL on a TDR is measured using the same method as all other portfolio loans, except when the value of a concession cannot be measured using a method other than the discounted cash flow method. When the value of a concession is measured using the discounted cash flow method, the ACL is determined by discounting the expected future cash flows at the original interest rate of the loan.

PCD assets are assets acquired at a discount that is due, in part, to credit quality deterioration since origination which may be determined through observation of missed payments, downgrade in risk rating, deterioration of a borrower's financial trends or other observable factors including subjectivity utilized by management. PCD assets 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 consolidated balance sheets, while the allowance for acquired non-PCD assets, such as loans, is recorded through the provision for credit losses on the consolidated statements of income, 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 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 these 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.

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.

Real Estate Owned

Real estate owned (REO) includes assets acquired through, or in lieu of, loan foreclosure. REO is held for sale and are initially recorded at fair value less estimated costs to sell at the date of acquisition, establishing a new cost basis. Physical possession of residential real estate property collateralizing a consumer mortgage loan occurs when legal title is obtained upon completion of foreclosure or when the borrower conveys all interest in the property to satisfy the loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Any write-downs based on the asset’s fair value less costs to sell at the date of acquisition are charged to the allowance for loan and lease losses. Any recoveries based on the asset’s fair value less estimated costs to sell in excess of the recorded value of the loan at the date of acquisition are recorded to the allowance for loan and lease losses. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. If fair value declines subsequent to foreclosure, a valuation allowance is recorded through expense. Operating costs after acquisition are expensed. Revenue and expenses from operations and changes in the valuation allowance are included in other non-interest expense, along with the gain or loss on sale of REO.

Premises and Equipment

Land is carried at cost. Land improvements, buildings and equipment, including those acquired under capital lease, are stated at cost less accumulated depreciation and amortization. Depreciation and amortization expenses are computed using the straight-line method over the shorter of the estimated useful lives of the related assets or lease terms. Asset lives range from 3-10 years for furniture and equipment and 15-40 years for land improvements and buildings.

Company Owned Life Insurance

The Company has purchased life insurance policies on certain key executives. Company owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.

As a result of current tax law and the nature of these policies, the Bank records any increase in cash value of these policies as nontaxable non-interest income. If the Bank decided to surrender any of the policies prior to the death of the insured, such surrender may result in a tax expense related to the life-to-date cumulative increase in cash value of the policy. If the Bank retains such policies until the death of the insured, the Bank would receive nontaxable proceeds from the insurance company equal to the death benefit of the policies. The Bank has

entered into Joint Beneficiary Agreements (JBAs) with certain of the insured that provide some level of sharing of the death benefit, less the cash surrender value, among the Bank and the beneficiaries of the insured upon the receipt of death benefits.

Goodwill, Other Intangible and Long-Lived Assets

Goodwill represents the excess of costs over fair value of net assets of businesses acquired from a business combination. The Company has an identifiable intangible asset consisting of core deposit intangibles (“CDI”). CDI are amortized over their respective estimated useful lives and reviewed periodically for impairment. Goodwill and other intangible assets acquired in a business combination and determined to have an indefinite useful life are not amortized, but instead tested for impairment at least annually. Other intangible assets with estimable useful lives are amortized over their respective estimated useful lives to their estimated residual values, and reviewed periodically for impairment.

As of September 30 of each year, goodwill is tested for impairment, and is tested for impairment more frequently if events and circumstances indicate that the asset might be impaired. An impairment loss is recognized to the extent that the carrying amount exceeds the asset’s fair value.

Long-lived assets, such as premises and equipment, and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of would be separately presented in the balance sheet and reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated. The assets and liabilities of a disposed group classified as held for sale would be presented separately in the appropriate asset and liability sections of the consolidated balance sheet.

Mortgage Servicing Rights

Mortgage servicing rights (“MSR”) represent the Company’s right to a future stream of cash flows based upon the contractual servicing fee associated with servicing mortgage loans. Our MSR arise from residential and commercial mortgage loans that we originate and sell, but retain the right to service the loans. The net gain from the retention of the servicing right is included in gain on sale of loans in non-interest income when the loan is sold. Fair value is based on market prices for comparable mortgage servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, the custodial earnings rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses. Servicing fees, when earned, and changes in fair value of the MSR, are recorded in non-interest income.

The Company accounts for MSR at fair value. The determination of fair value of our MSR requires management judgment because they are not actively traded. The determination of fair value for MSR requires valuation processes which combine the use of discounted cash flow models and extensive analysis of current market data to arrive at an estimate of fair value. The cash flow and prepayment assumptions used in our discounted cash flow model are based on empirical data drawn from the historical performance of our MSR, which we believe are consistent with assumptions used by market participants valuing similar MSR, and from data obtained on the performance of similar MSR. The key assumptions used in the valuation of MSR include mortgage prepayment speeds and the discount rate. These variables can, and generally will, change from quarter to quarter as market conditions and projected interest rates change. The key risks inherent with MSR are prepayment speed and changes in interest rates.

Leases

The Company records a right-of-use asset (“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 is also required to record a lease liability on the consolidated balance sheets for the present value of future payment commitments. Substantially 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 twelve months or less) within the ROUA and lease liability. Known or determinable adjustments to the required minimum future lease payments are 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 are not unknown and not determinable at lease commencement and therefore, are 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. The Company uses 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.

Off-Balance Sheet Credit Related Financial Instruments

In the ordinary course of business, the Company has entered into commitments to extend credit, including commitments under credit card arrangements, commercial letters of credit, and standby letters of credit. Such financial instruments are recorded when they are funded.

Low Income Housing Tax Credits

The Company accounts for low income housing tax credits and the related qualified affordable housing projects using the proportional amortization method. Under the proportional amortization method, the Company amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). Upon entering into a qualified affordable housing project, the Company records, in other liabilities, the entire amount that it has agreed to invest in the project, and an equal amount, in other assets, representing its investment in the project. As the Company disburses cash to satisfy its investment obligation, other liabilities are reduced. Over time, as the tax credits and other tax benefits of the project are realized by the Company, the investment recorded in other assets is reduced using the proportional amortization method.

Income Taxes

The Company’s accounting for income taxes is based on an asset and liability approach. The Company recognizes the amount of taxes payable or refundable for the current year, and deferred tax assets and liabilities for the future tax consequences that have been recognized in its financial statements or tax returns. The measurement of tax assets and liabilities is based on the provisions of enacted tax laws. A valuation allowance, if needed, reduces deferred tax assets to the expected amount most likely to be realized. Realization of deferred tax assets is dependent upon the generation of a sufficient level of future taxable income and recoverable taxes paid in prior years. Although realization is not assured, management believes it is more likely than not that all of the deferred tax assets will be realized.

A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. Interest and/or penalties related to income taxes are reported as a component of non-interest income.

Share-Based Compensation

Compensation cost is recognized for stock options and restricted stock awards issued to employees and directors, based on the fair value of the awards at the date of grant. The estimate of the fair value of stock options and performance based restricted awards are based on a Black-Scholes or Monte Carlo model, respectively, while the market price of the common stock at the date of grant is used for time based restricted awards. Compensation cost is recognized over the required service period, generally defined as the vesting or measurement period. The Company’s accounting policy is to recognize forfeitures as they occur.

Earnings per Share

Basic earnings per share represents income available to common shareholders divided by the weighted-average number of common shares outstanding during the period. There are no unvested share-based payment awards that contain rights to nonforfeitable dividends (participating securities). Diluted earnings per share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustments to income that would result from assumed issuance. Potential common shares that may be issued by the Company relate solely from outstanding stock options and restricted stock units, and are determined using the treasury stock method.

Revenue Recognition

The Company records revenue from contracts with customers in accordance with Accounting Standards Codification Topic 606, “Revenue from Contracts with Customers” (“Topic 606”). Under Topic 606, the Company must identify the contract with a customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract, and recognize revenue when (or as) the Company satisfies a performance obligation.

Most of our revenue-generating transactions are not subject to Topic 606, including revenue generated from financial instruments, such as our loans and investment securities. In addition, certain non-interest income streams such as fees associated with mortgage servicing rights, financial guarantees, derivatives, and certain credit card fees are also not in scope of the new guidance. The Company’s non-interest revenue streams are largely based on transactional activity, or standard month-end revenue accruals such as asset management fees based on month-end market values. Consideration is often received immediately or shortly after the Company satisfies its performance obligation and revenue is recognized. The Company does not typically enter into long-term revenue contracts with customers, and therefore, does not experience significant contract balances. As of December 31, 2022 and December 31, 2021, the Company did not have any significant contract balances. The Company has evaluated the nature of its revenue streams and determined that further disaggregation of revenue into more granular categories beyond what is presented in Note 18 was not necessary. The following are descriptions of revenues within the scope of ASC 606.

Deposit service charges

The Company earns fees from its deposit customers for account maintenance, transaction-based and overdraft services. Account maintenance fees consist primarily of account fees and analyzed account fees charged on deposit accounts on a monthly basis. The performance obligation is satisfied and the fees are recognized on a monthly basis as the service period is completed. Transaction-based fees on deposit accounts are charged to deposit customers for specific services provided to the customer, such as non-sufficient funds fees, overdraft fees, and wire fees. The performance obligation is completed as the transaction occurs and the fees are recognized at the time each specific service is provided to the customer.

Debit and ATM interchange fees

Debit and ATM interchange income represent fees earned when a debit card issued by the Company is used. The Company earns interchange fees from debit cardholder transactions through the Visa payment network. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder. The performance obligation is satisfied and the fees are earned when the cost of the transaction is charged to the cardholders’ debit card. Certain expenses directly associated with the credit and debit card are recorded on a net basis with the interchange income.

Commission on sale of non-deposit investment products

Commissions on sale of non-deposit investment products consist of fees earned from advisory asset management, trade execution and administrative fees from investments. Advisory asset management fees are variable, since they are based on the underlying portfolio value, which is subject to market conditions and asset flows. Advisory asset management fees are recognized quarterly and are based on the portfolio values at the end of each quarter. Brokerage accounts are charged commissions at the time of a transaction and the commission schedule is based upon the type of security and quantity. In addition, revenues are earned from selling insurance and annuity policies. The amount of revenue earned is determined by the value and type of each instrument sold and is recognized at the time the policy or contract is written.

Merchant fee income

Merchant fee income represents fees earned by the Company for card payment services provided to its merchant customers. The Company outsources these services to a third party to provide card payment services to these merchants. The third party provider passes the payments made by the merchants through to the Company. The Company, in turn, pays the third party provider for the services it provides to the merchants. These payments to the third party provider are recorded as expenses as a net reduction against fee income. In addition, a portion of the payment received represents interchange fees which are passed through to the card issuing bank. Income is primarily earned based on the dollar volume and number of transactions processed. The performance obligation is satisfied and the related fee is earned when each payment is accepted by the processing network.

Gain/loss on other real estate owned, net

The Company records a gain or loss from the sale of other real estate owned when control of the property transfers to the buyer, which generally occurs at the time of an executed deed of trust. When the Company finances the sale of other real estate owned to the buyer, the Company assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the other real estate owned asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on sale, the Company adjusts the transaction price and related gain or loss on sale if a significant financing component is present. Gains or losses from transactions associated with other real estate owned are recorded as a component of non-interest expense.

Reclassifications

Certain amounts reported in previous consolidated financial statements have been reclassified and recalculated to conform to the presentation in this report. These reclassifications did not affect previously reported amounts of net income, total assets or total shareholders’ equity.

Accounting Standards Adopted in 2022

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This ASU provides temporary optional guidance to ease the potential burden in accounting for reference rate reform by providing optional expedients and exceptions for applying generally accepted accounting principles (GAAP) to contracts, hedging relationships, and other transactions affected if certain criteria are met. At the time that Update 2020-04 was issued, the UK Financial

Conduct Authority (FCA) had established its intent that it would no longer be necessary to persuade, or compel, banks to submit to LIBOR after December 31, 2021. As a result, the sunset provision was set for December 31, 2022—12 months after the expected cessation date of all currencies and tenors of LIBOR. In March 2021, the FCA announced that the intended cessation date of the overnight 1-, 3-, 6-, and 12-month tenors of USD LIBOR would be June 30, 2023, which is beyond the current sunset date of Topic 848. Because the current relief in Topic 848 may not cover a period of time during which a significant number of modifications may take place, the amendments in this

Update defer the sunset date of Topic 848 from December 31, 2022, to December 31, 2024. As the Company has an insignificant number of instruments that are applicable to this ASU, management has determined that no impact to the valuations of these instruments are applicable for financial reporting purposes.

Accounting Standards Pending Adoption

In March 2022, the FASB issued ASU 2022-02, Financial Instruments — Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. The amendments in this Update eliminate the TDR recognition and measurement guidance and, instead, require that an entity evaluate (consistent with the accounting for other loan modifications) whether the modification represents a new loan or a continuation of an existing loan. The amendments enhance existing disclosure requirements and introduce new requirements related to certain modifications of receivables made to borrowers experiencing financial difficulty. Furthermore, the amendments in this Update require that an entity disclose current-period gross write-offs by year of origination for financing receivables and net investment in leases within the scope of Subtopic 326-20. The Company adopted these amendments on January 1, 2023 and has thus far observed no material impact to

deferred fees and costs and the related timing of net interest income recognition as a result of adoption.

Business Combinations

On March 25, 2022, the Company completed its acquisition of Valley Republic Bancorp (VRB), including the merger of Valley Republic Bank into Tri Counties Bank, with Tri Counties Bank as the surviving entity, in accordance with the terms of the merger agreement dated as of July 27, 2021. The cash and stock transaction was valued at $174,016,000 in aggregate, based on TriCo's closing stock price of $42.48 on March 25, 2022. Under the terms of the merger agreement, the Company issued 4,105,518 shares, in addition to approximately $431,000 in cash paid out for settlement of stock option awards at VRB.

The acquisition of VRB has been accounted for as a business combination. The Company recorded the fair values based on the valuations available as of acquisition date, and subject to adjustment up to one year following the merger date of March 25, 2022. During the fourth quarter of 2022, an adjustment to the initial allocation was based on more detailed information obtain about tax-related matters. Management believes the purchase price allocation is now finalized as December 31, 2022.

The following table summarizes the consideration paid for VRB and the amounts of assets acquired and liabilities assumed that were recorded at the acquisition date (in thousands):

There were no sales of debt securities during the years ended December 31, 2022 and 2021, respectively. During 2020, proceeds from sales of debt securities totaled $229,000, resulting in gross gains of $7,000. Investment securities with an aggregate carrying value of $595,779,000 and $423,892,000 at December 31, 2022 and 2021, respectively, were pledged as collateral for specific borrowings, lines of credit and local agency deposits.

The amortized cost and estimated fair value of debt securities at December 31, 2022 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 December 31, 2022, obligations of U.S. government and agencies with an amortized cost basis totaling $1,533,255,000 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 December 31, 2022, the Company estimates the average remaining life of these mortgage-backed securities issued by U.S. government corporations and agencies to be approximately 6.4 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: Unrealized losses on investments in obligations of U.S. government corporations and agencies are caused by interest rate increases. 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 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, these investments are not considered other-than-temporarily impaired. At December 31, 2022, 172 debt securities representing obligations of U.S. government corporations and agencies had unrealized losses with aggregate depreciation of 12.48% from the Company’s amortized cost basis.

Obligations of states and political subdivisions: The unrealized losses on investments in obligations of states and political subdivisions were caused by increases in required yields by investors in these types of securities. It is expected that the securities would not be settled at a price less than the amortized cost of the investment. Because 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, these investments are not considered other-than-temporarily impaired. At December 31, 2022, 202 debt security representing obligations of states and political subdivisions had unrealized losses with aggregate depreciation of 13.16% from the Company’s amortized cost basis.

Corporate bonds: The unrealized losses on investments in corporate bonds were caused by increases in required yields by investors in these types of securities. 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 and there has been no allowance for credit losses as of and for the year ended December 31, 2022. At December 31, 2022, 6 asset backed securities had unrealized losses with aggregate depreciation of 6.70% from the Company’s amortized cost basis.

Asset backed securities: The unrealized losses on investments in asset backed securities were caused by increases in required yields by investors in these types of securities. At the time of purchase, each of these securities were rated AA or AAA and through December 31, 2022 have not experienced any deterioration in credit rating. The Company continues to monitor these securities for changes in credit rating or other indications of credit deterioration. 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, these investments are not considered other-than-temporarily impaired. At December 31, 2022, 48 asset backed securities had unrealized losses with aggregate depreciation of 3.36% from the Company’s amortized cost basis.

Non-agency collateralized mortgage obligations: The unrealized losses on investments in asset backed securities were caused by increases in required yields by investors in these types of securities. 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 and there has been no allowance for credit losses as of and for the year ended December 31, 2022. At December 31, 2022, 22 asset backed securities had unrealized losses with aggregate depreciation of 10.88% from the Company’s amortized cost basis.

Marketable equity securities: As there were no sales of marketable equity securities, all unrealized gains or losses recognized during the reporting period were for equity securities still held as of the end of the reporting period.

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

Allowance For Loan And Lease Losses [Abstract]

Allowance for Credit Losses

Allowance for Credit Losses

The ACL was $105,680,000 as of December 31, 2022 as compared to $85,376,000 at December 31, 2021. The provision for credit losses on loans of $17,945,000 during the year ended December 31, 2022 was comprised of $10,820,000 in day 1 required reserves from loans acquired in connection with the VRB merger in the first quarter of 2022. Additionally, the Company designated certain loans and leases purchased from VRB as PCD, which required $2,037,000 in additional credit reserves as of the acquisition date. For PCD loans and leases, the initial estimate of expected credit losses is recognized in the ACL on the date of acquisition using the same methodology as other loans and leases held-for-investment.

The remaining increase in the allowance for credit reserves was the result of changes in loan volume and changes in credit quality associated with levels of classified, past due and non-performing loans in addition to changes in qualitative factors. The quantitative component of the ACL increased reserve requirements due to loan volume growth and increases in specific reserves. In addition to the quantitative loan portfolio, credit quality characteristics which are illustrated in the following tabular disclosures, the Company’s expected credit loss methodology (CECL) incorporates the use of qualitative factors. The qualitative components of the ACL resulted in a net increase in required reserves despite continued improvement in US employment rates, due to increased uncertainty in the global economic markets, US economic policy uncertainty, and the continued rise in corporate debt yields. As compared to historical norms, inflation remains elevated from continued disruptions in the supply chain, wage pressures, and higher living costs such as housing and food prices. Management notes the rapid intervals of rate increases by the Federal Reserve and inversion of the yield curve, have boosted expectations of the US entering a recession within 12 months. As a result, management continues to believe that certain credit weakness are likely present in the overall economy and that it is appropriate to maintain an allowance for credit losses that incorporates such risk factors.

The table below sets forth the components of the Company’s allowance for credit losses as of the dates indicated:

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 $1,000,000 and non-homogeneous loans, such as commercial real estate loans, unless other indicators, such as delinquency, trigger more frequent evaluation. Loans below the $1,000,000 threshold and homogenous in nature are evaluated as needed for proper grading based on delinquency and borrower credit scores.

Collateral values may be determined by appraisals obtained through Bank approved, licensed appraisers, qualified independent third parties, public value information (blue book values for autos), sales invoices, or other appropriate means. Appropriate valuations are obtained at initiation of the credit and periodically (every 3-12 months depending on collateral type) once repayment is questionable and the loan has been classified.

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.

Once a loan becomes delinquent and repayment becomes questionable, a Bank collection officer will address collateral shortfalls with the borrower and attempt to obtain additional collateral. If this is not forthcoming and payment in full is unlikely, the Bank will estimate its probable loss, using a recent valuation as appropriate to the underlying collateral less estimated costs of sale, and charge the loan down to the estimated net realizable amount. Depending on the length of time until ultimate collection, the Bank may revalue the underlying collateral and take additional charge-offs as warranted. Revaluations may occur as often as every 3-12 months depending on the underlying collateral and volatility of values. Final charge-offs or recoveries are taken when collateral is liquidated and actual loss is known. Unpaid balances on loans after or during collection and liquidation may also be pursued through lawsuit and attachment of wages or judgment liens on borrower’s other assets.

For all new TDRs, an impairment analysis is conducted. If the loan is determined to be collateral dependent, any additional amount of impairment will be calculated based on the difference between estimated collectible value and the current carrying balance of the loan. This difference could result in an increased provision and is typically charged off. If the asset is determined not to be collateral dependent, the impairment is measured on the net present value difference between the expected cash flows of the restructured loan and the cash flows which would have been received under the original terms. The effect of this could result in a requirement for additional provision to the reserve. The effect of these required provisions for the period are indicated above.

Typically if a TDR defaults during the period, the loan is then considered collateral dependent and, if it was not already considered collateral dependent, an appropriate provision will be reserved or charge will be taken. The additional provisions required resulting from default of previously modified TDR’s are noted above.

Goodwill	$	304,442	$	83,570	$	—	$	220,872

Impairment exists when a Company’s carrying value exceeds its fair value. Goodwill is evaluated for impairment annually. At September 30, 2022, the Company had positive equity and the Company elected to perform a qualitative assessment to determine if it was more likely than not that the fair value of the Company exceeded its carrying value, including goodwill. The qualitative assessment indicated that it was more likely than not that the fair value of the reporting unit exceeds its carrying value, resulting in no impairment. For each of the years in the three year period ended December 31, 2022, there were no impairment charges recognized.

The following table summarizes the Company’s core deposit intangibles (“CDI”) as of the dates indicated:

The changes in fair value of MSRs during 2022 were primarily due to changes in mortgage prepayment speeds and expected life estimates of the MSRs. The changes in fair value of MSRs during 2021 were primarily due to changes in principal balance and mortgage prepayment speeds of the MSRs. The changes in fair value of MSRs during 2020 were primarily due to changes in investor require rate of return, or discount rate, of the MSRs.

Equity [Abstract]

Junior Subordinated Debt

Junior Subordinated Debt

At December 31, 2022, the Company had five wholly-owned subsidiary business trusts that had issued $63.0 million of trust preferred securities (the “Capital Trusts”). Trust preferred securities accrue and pay distributions periodically at specified annual rates as provided in the indentures. The trusts used the net proceeds from the offering to purchase a like amount of subordinated debentures (the “Debentures”) of the Company. The Debentures are the sole assets of the trusts. The Company’s obligations under the subordinated debentures and related documents, taken together, constitute a full and unconditional guarantee by the Company of the obligations of the trusts. The trust preferred securities are mandatorily redeemable upon the maturity of the Debentures, or upon earlier redemption as provided in the indentures. The Company has the right to redeem the Debentures in whole (but not in part) on or after specific dates, at a redemption price specified in the indentures plus any accrued but unpaid interest to the redemption date. The Company also has a right to defer consecutive payments of interest on the debentures for up to five years.

The Company organized two of the Capital Trusts. The Company acquired its three other Capital Trusts and assumed their related Debentures as a result of its acquisition of North Valley Bancorp in 2014. The acquired Debentures were recorded on the Company’s books at their fair values on the acquisition date. The related fair value discounts to face value of these Debentures will be amortized over the remaining period in which their values are fully allowed to be included in the Company's capital ratio calculations using the effective interest method.

The recorded book values of the Debentures issued by the Capital Trusts are reflected as junior subordinated debt in the Company’s consolidated balance sheets. The common stock issued by the Capital Trusts and owned by the Company is recorded in other assets in the

Company’s consolidated balance sheets. The recorded book value of the debentures issued by the Capital Trusts, less the recorded book value of the common stock of the Capital Trusts owned by the Company will continue to qualify as Tier 1 or Tier 2 capital under interim guidance issued by the Board of Governors of the Federal Reserve System until only five years remain until their scheduled maturity.

In connection with the acquisition of Valley Republic Bancorp the Company assumed $36.0 million in subordinated capital notes, comprised of $16.0 million that matures in 2029 and $20.0 million that matures in 2035. The notes that mature in 2029 provide for quarterly interest payments at a fixed rate of 6.00% until March 29, 2024 and then will have a floating rate of three month LIBOR plus 3.52% until maturity. The notes that mature in 2035 provide for quarterly interest payments at a fixed rate of 5.00% until August 27, 2025 and then will have a floating rate of 90-day average SOFR plus 4.90% until maturity. The acquired subordinated capital notes were recorded on the Company’s books at their fair values on the acquisition date. The related fair value premiums to face value will be amortized over the remaining maturity period using the effective interest method. The Company expects a comparable SOFR rate term to replace LIBOR as the benchmark rate index for applicable debentures in 2024.

The following table summarizes the terms and recorded balance of each subordinated debenture as of the date indicated (dollars in thousands):

Commitments and Contingencies

Commitments and Contingencies

Restricted Cash Balances — Reserves (in the form of deposits with the San Francisco Federal Reserve Bank) were not required to be maintained as of December 31, 2022 and 2021.

Financial Instruments with Off-Balance-Sheet Risk — The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, standby letters of credit, and deposit account overdraft privilege. Those instruments involve, to varying degrees, elements of risk in excess of the amount recognized in the balance sheet. The contract amounts of those instruments reflect the extent of involvement the Company has in particular classes of financial instruments.

The Company’s exposure to loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit written is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. The Company’s exposure to loss in the event of nonperformance by the other party to the financial instrument for deposit account overdraft privilege is represented by the overdraft privilege amount disclosed to the deposit account holder.

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

	December 31,
(in thousands)	2022		2021
Financial instruments whose amounts represent risk:
Commitments to extend credit:
Commercial loans	$	656,705	$	409,950
Consumer loans	760,588		628,791
Real estate mortgage loans	458,896		333,764
Real estate construction loans	312,371		213,563
Standby letters of credit	26,599		21,871
Deposit account overdraft privilege	126,634		125,670

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates of one year or less or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on Management’s credit evaluation of the customer. Collateral held varies, but may include accounts receivable, inventory, property, plant and equipment, residential properties, and income-producing commercial properties.

Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support private borrowing arrangements. Most standby letters of credit are issued for one year or less. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. Collateral requirements vary, but in general follow the requirements for other loan facilities.

Deposit account overdraft privilege amount represents the unused overdraft privilege balance available to the Company’s deposit account holders who have deposit accounts covered by an overdraft privilege. The Company has established an overdraft privilege for certain of its deposit account products whereby all holders of such accounts who bring their accounts to a positive balance at least once every thirty days receive the overdraft privilege. The overdraft privilege allows depositors to overdraft their deposit account up to a predetermined level. The predetermined overdraft limit is set by the Company based on account type.

Legal Proceedings — Neither the Company nor its subsidiaries are a party to any other pending legal proceedings that are material, nor is their property the subject of any other material pending legal proceeding at this time. All other legal proceedings are routine and arise out of the ordinary course of the Bank’s business. None of those proceedings are currently expected to have a material adverse impact upon the Company’s and the Bank’s business, their consolidated financial position nor their operations in any material amount not already accrued, after taking into consideration any applicable insurance.

Other Commitments and Contingencies—The Company has entered into employment agreements or change of control agreements with certain officers of the Company providing severance payments and accelerated vesting of benefits under supplemental retirement agreements to the officers in the event of a change in control of the Company and termination for other than cause or after a substantial and material change in the officer’s title, compensation or responsibilities.

The Bank owns 13,396 shares of Class B common stock of Visa Inc. which are convertible into Class A common stock at a conversion ratio of 1.5991 per Class B share. As of December 31, 2022, the value of the Class A shares was $207.76 per share. Utilizing the conversion ratio, the value of unredeemed Class A equivalent shares owned by the Bank was $4,451,000 as of December 31, 2022, and has not been reflected in the accompanying consolidated financial statements. The shares of Visa Class B 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 conversion ratio will be increased to reflect that surplus.

Mortgage loans sold to investors may be sold with servicing rights retained, with only the standard legal representations and warranties regarding recourse to the Bank. Management believes that any liabilities that may result from such recourse provisions are not significant.

Dividends Paid

The Bank paid to the Company cash dividends in the aggregate amounts of $64,188,000, $31,571,000, and $63,419,000 in 2022, 2021, and 2020, respectively. The Bank is regulated by the Federal Deposit Insurance Corporation (“FDIC”) and the State of California Department of Financial Protection & Innovation (the “DFPI”). Absent approval from the Commissioner of the DPFI, 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. Under this law, at December 31, 2022, the Bank could have paid dividends of $157,036,000 to the Company without the approval of the Commissioner of the DFPI.

Stock Repurchase Plan

On February 25, 2021 the Board of Directors approved the authorization to repurchase 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 program is subject to change. The 2021 Repurchase Plan has no expiration date (in accordance with applicable laws and regulations) and as of and for year ended December 31, 2022, the Company repurchased 576,881 shares. The Company repurchased 63,317 shares during the year ended December 31, 2021.

In connection with approval of the 2021 Repurchase Plan, the Company’s previous repurchase program adopted on November 12, 2019 (the 2019 Repurchase Plan) was terminated. Under the 2019 Repurchase Plan, during the years ended December 31, 2021 and 2020 the Company had repurchased 223 and 858,717 shares, 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 withholding taxes on such shares. During the years ended December 31, 2022, 2021, and 2020, employees tendered 39,447, 28,276, and 12,488 shares, respectively, of the Company's common stock in connection with option exercises. Employees also tendered 27,840, 19,413 and 12,058 shares in connection with other share based awards during December 31, 2022, 2021 and 2020, respectively. In total, shares of the Company's common stock tendered had market values of $1,269,000, $2,118,000, and $736,000 for the years ended December 31, 2022, 2021 and 2020, respectively. 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 or 2019 Repurchase Plans.

Stock Options and Other Equity-Based Incentive Instruments

Stock Options and Other Equity-Based Incentive Instruments

In April 2019, the Company’s Board of Directors adopted the TriCo Bancshares 2019 Equity Incentive Plan (2019 Plan) covering officers, employees, directors of, and consultants to, the Company. The 2019 Plan was approved by the Company’s shareholders in May 2019. The 2019 Plan allows the Company to issue equity-based incentives representing up to 1,500,000 shares, such as incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock, restricted stock units and performance awards (which could either be restricted stock or restricted stock units) (collectively, Awards). The 2019 Plan contains several enhanced corporate governance provisions, including: expressly providing that executives’ Awards and cash incentive compensation are subject to TriCo’s potential clawback or recoupment if the Company must restate its financial statements; generally imposing a one year minimum vesting period on Awards; generally requiring participants to hold at least 50% of the shares acquired under an Award for at least one year; and clarifying that credit for dividends declared on shares of common stock underlying an Award is subject to the same vesting requirements as the common stock underlying the Award.

The number of shares available for issuance under the 2019 Plan will be reduced by: (i) one share for each share of common stock issued pursuant to a stock option; (ii) the total number of stock appreciation rights that are exercised, including any shares of common stock underlying such Awards that are not actually issued to the participant as the result of a net settlement; (iii) two shares for each share of common stock issued pursuant to a performance award, a restricted share Award or an RSU Award and (iv) any shares of common stock used to pay any exercise price or tax withholding obligation with respect to any Award. When Awards made under the 2019 Plan expire or are forfeited or cancelled, the underlying shares will become available for future Awards under the 2019 Plan. To the extent that a share of common stock pursuant to an Award that counted as two shares again becomes available for issuance under the 2019 Plan, the number of shares of common stock available for issuance under the 2019 Plan will increase by two shares. If shares of common stock issued pursuant to the Plan are repurchased by, or are surrendered or forfeited to the Company at no more than cost, then such shares will again be available for the grant of Awards under the Plan. Any shares of common stock repurchased by the Company with cash proceeds from the exercise of options will not, however, be added back to the pool of share available for issuance under the 2019 Plan. Shares awarded and delivered under the 2019 Plan may be authorized but unissued shares or reacquired shares. Shares tendered to TriCo or withheld from delivery to a participant as payment of the exercise price or in connection with the “net exercise” of a stock option or to satisfy TriCo’s tax withholding obligations will not again become available for future Awards under the 2019 Plan. As of December 31, 2022, there were no outstanding options for the purchase of common shares and 139,194 RSUs were outstanding. The number of shares that remain available for issuance is not more than 763,495, which could decrease based on the level of the Company's future performance and outcome of certain vesting requirements.

The 2019 Plan replaced the TriCo Bancshares 2009 Equity Incentive Plan (2009 Plan), which expired on March 26, 2019. As a result of its expiration, no further awards may be issued under the 2009 Plan, though all awards under the 2009 Plan that were outstanding as of its expiration continue to be governed by the terms, conditions and procedures set forth in the 2009 Plan and any applicable award agreement. As of December 31, 2022, 15,500 options for the purchase of common shares remain outstanding under the 2009 Plan.

Stock option activity is summarized in the following table for the dates indicated:

	Number of Shares	Option Price per Share	Weighted Average Exercise Price

RSUs forfeited/expired	(1,421)			(1,561)
Outstanding at December 31, 2022	139,194			114,481

The 139,194 of service condition vesting RSUs outstanding as of December 31, 2022 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. Additional RSUs credited through dividends are subject to the same vesting requirements as the original grant. The Company expects to recognize $3,822,000 of pre-tax compensation costs related to these service condition vesting RSUs between December 31, 2022 and their vesting dates. The Company did not modify any service condition vesting RSUs during 2022 or 2021.

The Company expects to recognize $2,110,000 of pre-tax compensation costs related to the market plus service condition RSUs between December 31, 2022 and their vesting dates. As of December 31, 2022, 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 171,721 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 2022 or 2021.

The following table shows the compensation costs and excess tax benefits for RSUs recognized in income for the periods indicated:

	Year Ended December 31,

As part of the merger with FNB Bancorp in 2018 and North Valley Bancorp in 2014, TriCo acquired federal and state net operating loss carryforwards, capital loss carryforwards, and tax credit carryforwards. In addition, the 2020 Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) provided the Company with an opportunity to file amended federal tax returns and generate proposed refunds of approximately $805,000. These tax attribute carryforwards will be subject to provisions of the tax law that limit the use of such losses and

credits generated by a company prior to the date certain ownership changes occur. The amount of the Company’s net operating loss carryforwards that are subject to these limitations as of December 31, 2022 were approximately $5,518,000 for federal and $11,187,000 for California. The amount of the Company’s tax credits that would be subject to these limitations as of December 31, 2022 are $395,000 and $648,000 for federal and California, respectively. Due to the limitation, a significant portion of the state tax credits will expire regardless of whether the Company generates future taxable income. As such, the Company has recorded the future benefit of these tax credits on the books at the value which is more likely than not to be realized. These tax loss and tax credit carryforwards expire at various dates through 2032.

The Company believes that a valuation allowance is not needed to reduce the deferred tax assets as it is more likely than not that the results of future operations will generate sufficient taxable income to realize the deferred tax assets, including the tax attribute carryforwards acquired as part of past mergers.

Disclosure of unrecognized tax benefits at December 31, 2022 and 2021 were not considered significant for disclosure purposes. Management does not expect the unrecognized tax benefit will materially change in the next 12 months. During the years ended December 31, 2022 and December 31, 2021 the Company did not recognize and significant amounts related to interest and penalties associated with taxes. The Company files income tax returns in the U.S. federal jurisdiction, and California. With few exceptions, the Company is no longer subject to U.S. federal and state/local income tax examinations by tax authorities for years before 2019 and 2018, respectively.

Retirement Plans

401(k) Plan

The Company sponsors a 401(k) Plan whereby substantially all employees age 21 and over with 90 days of service may participate. Participants may contribute a portion of their compensation subject to certain limits based on federal tax laws. The Company provides a discretionary matching contribution equal to 50% of participant’s elective deferrals, up to 4% of eligible compensation. The Company recorded salaries & benefits expense attributable to the 401(k) Plan matching contributions and 401(k) Plan matching contributions for the years ended:

Employee Stock Ownership Plan

Substantially all employees with at least one year of service are covered by a discretionary employee stock ownership plan (ESOP). Company shares owned by the ESOP are paid dividends and included in the calculation of earnings per share as common shares outstanding. Contributions are made to the plan at the discretion of the Board of Directors. Expenses related to the Company’s ESOP, included in benefits and other compensation costs under salaries and benefits expense, and contributions to the plan for the years ended were:

	Year Ended December 31,

ESOP contributions made by the Company	$	3,535	$	878	$	1,951

Deferred Compensation Plans

The Company has deferred compensation plans for certain directors and key executives, which allow certain directors and key executives designated by the Board of Directors of the Company to defer a portion of their compensation. The Company has purchased insurance on the lives of certain of the participants and intends to hold these policies until death as a cost recovery of the Company’s deferred compensation obligations of $5,738,000 and $5,945,000 at December 31, 2022 and 2021, respectively. Earnings credits on deferred balances included in non-interest expense are included in the following table:

	Year Ended December 31,
(in thousands)	2022		2021		2020
Deferred compensation earnings credits included in non-interest expense	$	187	$	176	$	212

Supplemental Retirement Plans

The Company has supplemental retirement plans for certain directors and key executives. These plans are non-qualified defined benefit plans and are unsecured and unfunded. The Company has purchased insurance on the lives of the participants and intends to hold these policies until death as a cost recovery of the Company’s retirement obligations. The cash values of the insurance policies purchased to fund the deferred compensation obligations and the supplemental retirement obligations were $133,742,000 and $117,857,000 at December 31, 2022 and 2021, respectively.

The Company recorded in other liabilities the additional funded status of the supplemental retirement plans of $13,901,000 and $2,399,000 related to the supplemental retirement plans as of December 31, 2022 and 2021, respectively. These amounts represent the amount by which the projected benefit obligations for these retirement plans exceeded the fair value of plan assets plus amounts previously accrued related to the plans. The projected benefit obligation is recorded in other liabilities.

At December 31, 2022 and 2021, the additional funded status of the supplemental retirement plans of $13,901,000 and $2,399,000 were offset by a reduction of shareholders’ equity accumulated other comprehensive gain of $9,792,000 and $1,690,000, respectively, representing the after-tax impact of the additional funded status of the supplemental retirement plans, and the related deferred tax liability of $4,109,000 and $709,000, respectively. Amounts recognized as a component of accumulated other comprehensive income (loss) as of year-end that have not been recognized as a component of the combined net period benefit cost of the Company’s defined benefit pension plans are presented in the following table. The Company expects to recognize approximately $455,000 of the net actuarial loss reported in the following table as of December 31, 2022 as a component of net periodic benefit cost during 2022.

Fair Value Measurement

Dec. 31, 2022

Fair Value Disclosures [Abstract]

Fair Value Measurement

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. Securities available-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 as loans held for sale, loans held for investment and certain other assets. These nonrecurring fair value adjustments typically involve application of lower of cost or market accounting or 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.

Securities available for sale—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 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 nonrecurring 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, loans may require individual analysis and an allowance for credit losses is established. Loans for which it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement are an example. The fair value of individually evaluated loans is estimated using one of several methods, including collateral value, fair value of similar debt, enterprise value, liquidation value and discounted cash flows. Those individually evaluated 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. Individually evaluated 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 below the appraised value, or the appraised value contains a significant unobservable assumption, such as deviations from comparable sales, and there is no observable market price, the Company records the loan as nonrecurring Level 3.

Foreclosed assets—Foreclosed assets include assets acquired through, or in lieu of, loan foreclosure. Foreclosed assets are held for sale and are initially recorded at fair value at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, management periodically performs valuations and the assets are carried at the lower of carrying amount or fair value less cost to sell. When the fair value of foreclosed assets is based on an observable market price or a current appraised value which uses substantially observable data, the Company records the asset 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. Additional information regarding mortgage servicing rights can be found in Note 10 in the consolidated financial statements at Item 1 of this report.

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

Year ended December 31,	Beginning Balance		Transfers into (out of) Level 3	Change Included in Earnings		Issuances		Ending Balance
2022: Mortgage servicing rights	$	5,874	—	$	301	$	537	$	6,712
2021: Mortgage servicing rights	$	5,092	—	$	(872)	$	1,654	$	5,874
2020: Mortgage servicing rights	$	6,200	—	$	(2,634)	$	1,526	$	5,092

The Company’s method for determining the fair value of mortgage servicing rights is described in Note 1. 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). Note 10 contains additional information regarding mortgage servicing rights.

The following table present quantitative information about recurring Level 3 fair value measurements at December 31, 2022 and 2021:

December 31, 2022	Fair Value (in thousands)	Valuation Technique	Unobservable Inputs	Range, Weighted Average
Mortgage Servicing Rights	$6,712	Discounted cash flow	Constant prepayment rate	116%-226%, 127%
			Discount rate	10%-14%, 12%
December 31, 2021
Mortgage Servicing Rights	$5,874	Discounted cash flow	Constant prepayment rate	187%-264%, 208%
			Discount rate	10%-14%, 12%

The tables below present the recorded amount of assets and liabilities measured at fair value on a nonrecurring basis, as of the dates indicated, that had a write-down or an additional allowance provided during the periods indicated. The gains (losses) represent the amounts recorded during the period regardless of whether the asset is still held at fair value at period end (in thousands):

December 31, 2022	Total		Level 1	Level 2	Level 3		Total Gains (Losses)
Fair value:
Individually evaluated loans	$	5,719	—	—	$	5,719	$	(2,283)
Real estate owned	311		—	—	311		481
Total assets measured at fair value	$	6,030	—	—	$	6,030	$	(1,802)

December 31, 2021	Total		Level 1	Level 2	Level 3		Total Gains (Losses)
Fair value:
Individually evaluated loans	$	3,683	—	—	$	3,683	$	(1,105)

The individually evaluated loan amount above represents collateral dependent loans with unique risk characteristics that have been adjusted to fair value. When we identify a collateral dependent loan as requiring individual evaluation, we measure the need for credit reserves 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 we determine that the value of the loan is less than the recorded investment in the loan, we recognize this impairment and adjust the carrying value of the loan to fair value through the allowance for loan and lease 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 Bank 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 loan and lease losses. After foreclosure, management periodically performs valuations such that the real estate is carried at the lower of its new cost basis or fair value, net of estimated costs to sell. Fair value adjustments on other real estate owned are recognized within net loss on real estate owned. The loss represents impairments on non-covered other real estate owned for fair value adjustments based on the fair value of the real estate.

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

The following tables present quantitative information about Level 3 fair value measurements for financial instruments measured at fair value on a nonrecurring basis at December 31, 2022 and 2021:

December 31, 2022	Fair Value (in thousands)		Valuation Technique	Unobservable Inputs	Range, Weighted Average
Individually evaluated loans	$	5,719	Sales comparison approach Income approach	Adjustment for differences between comparable sales; Capitalization rate	Not meaningful; N/A

The estimated fair values of financial instruments that are reported at amortized cost in the Corporation’s consolidated balance sheets, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value, were as follows (in thousands):

	December 31, 2022				December 31, 2021

Standby letters of credit (1)	26,599		266		21,871		219
Overdraft privilege commitments (1)	126,634		1,266		125,670		1,257

The methods and assumptions used to estimate the fair value of each class of financial instruments not measured at fair value are as follows:

Securities held to maturity - This includes mortgage-backed securities issued by government sponsored entities and municipal bonds. 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.

Restricted equity securities - Consists of FHLB stock whereby carrying value approximates fair value.

Loans - Loans are generally valued by discounting expected cash flows using market inputs with adjustments based on cohort level assumptions for certain loan types as well as internally developed estimates at a business segment level. Due to the significance of the unobservable market inputs and assumptions, as well as the absence of a liquid secondary market for most loans, these loans are classified as Level 3. Certain loans are measured based on observable market prices sourced from external data providers and classified as Level 2. Nonaccrual loans are written down and reported at their estimated recovery value which approximates their fair value and classified as Level 3.

Deposits - The estimated fair value of deposits with no stated maturity, such as demand deposit accounts, money market accounts, and savings accounts was the amount payable on demand at the reporting date. The fair value of time deposits was estimated based on a discounted cash flow technique using Level 3 inputs appropriate to the contractual maturity.

Other borrowings - The cash flows were calculated using the contractual features of the advance and then discounted using observable market. These are short-term in nature.

Junior subordinated debt - The fair value of structured financings was estimated based on a discounted cash flow technique using observable market interest rates adjusted for estimated spreads.

(1) Lending related commitments - The fair value of these commitments, including revolving credit facilities, standby letters of credit and overdrafts are carried at contract value, which approximates fair value but are not actively traded. These instruments generate fees, which approximate those currently charged to originate similar commitments, which are recognized over the term of the commitment period.

Regulated Operations [Abstract]

Regulatory Matters

Regulatory Matters

The Company and the Bank are 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 consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action specific capital guidelines that involve quantitative measures of assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. These 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 that minimum amounts and ratios of total, Tier 1, and common equity Tier 1capital to risk-weighted assets, and of Tier 1 capital to average assets be maintained. Under applicable capital requirements both the Company and the Bank are required to have a common equity Tier 1 capital ratio of 4.5%, a Tier 1 leverage ratio of 4.0%, a Tier 1 risk-based ratio of 6.0% and a total risk-based ratio of 8.0%. In addition, the Company and the Bank are also required to maintain a capital conservation buffer consisting of common equity Tier 1 capital above 2.5% of minimum risk based capital ratios to avoid restrictions on certain activities including payment of dividends, stock repurchases and discretionary bonuses to executive officers. The additional 2.5% buffer, where applicable, is included in the minimum ratios set forth in the table below. Management believes as of December 31, 2022 and 2021, the Company and Bank meet all capital adequacy requirements to which they are subject.

Accounting Policies [Abstract]

Description of Business and Basis of Presentation

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 and retail banking business in 32 California counties. 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 obtained through acquisition.

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. For financial reporting purposes, the Company’s investments in the Capital Trusts of $1,757,000 are accounted for under the equity method and, accordingly, are included in other assets on the consolidated balance sheets. The subordinated debentures issued and guaranteed by the Company and held by the Capital Trusts are reflected as debt on the Company’s consolidated balance sheets.

Use of Estimates in the Preparation of Financial Statements

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.

Segment and Significant Group Concentration of Credit Risk

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

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.

Business Combinations

Business Combinations

The Company accounts for acquisitions of businesses using the acquisition method of accounting. Under the acquisition method, assets acquired and liabilities assumed are recorded at their estimated fair values at the date of acquisition. Management utilizes various valuation techniques including discounted cash flow analyses to determine these fair values. Any excess of the purchase price over amounts allocated to the acquired assets, including identifiable intangible assets, and liabilities assumed is recorded as goodwill.

Cash and Cash Equivalents

Cash and Cash Equivalents

For purposes of the consolidated statements of cash flows, cash and cash equivalents include cash on hand, amounts due from banks, and federal funds sold. Net cash flows are reported for loan and deposit transactions and other borrowings.

Non-Marketable and Other Equity Securities

Non-Marketable and Other Equity Securities

Non-marketable and other equity securities include qualified public welfare investments and venture capital/private equity funds. Our accounting for investments in non-marketable and other equity securities depends on several factors, including the level of ownership, power to control and the legal structure of the subsidiary making the investment. We base our accounting for such securities on: (i) fair value accounting, (ii) measurement alternative for other investments without a readily determinable fair value, and (iii) equity method accounting. During the twelve months ended December 31, 2022 and 2021, the Company recognized net unrealized gains of $35,000 and $718,000, respectively, in the consolidated statements of net income related to changes in the fair value of non-marketable and other equity securities.

Debt Securities

Debt Securities

The Company classifies its debt securities into one of three categories: trading, available for sale or held to maturity. Trading securities are bought and held principally for the purpose of selling in the near term and changes in the value of these securities are recorded through earnings. Held to maturity securities are those securities which the Company has the ability and intent to hold until maturity. These securities are carried at cost adjusted for amortization of premium and accretion of discount, computed by the effective interest method over their contractual lives. All other securities not included in trading or held to maturity are classified as available for sale. AFS securities are recorded at fair value. Unrealized gains and losses, net of the related tax effect, on available for sale securities are reported as a separate component of other accumulated comprehensive income in shareholders’ equity until realized. Discounts are amortized or accreted over the expected life of the related investment security as an adjustment to yield using the effective interest method. Premiums on callable debt securities are generally amortized to the earliest call date of the security with the exception of mortgage backed securities, where estimated prepayments, if any, are considered. Dividend and interest income are recognized when earned. Realized gains and losses are derived from the amortized cost of the security sold. The Company did not have any debt securities classified as trading during the three year period ended December 31, 2022.

The Company has made a policy election to exclude accrued interest from the amortized cost basis of debt securities and report accrued interest separately in the consolidated balance sheets. A debt security is placed on nonaccrual status at the time any principal or interest payments become more than 90 days delinquent or if full collection of interest or principal becomes uncertain. Accrued interest for a security placed on nonaccrual is reversed against interest income. There was no accrued interest related to debt securities reversed against interest income for the years ended December 31, 2022, 2021 and 2020.

The Company evaluates available for sale debt securities in an unrealized loss position to determine whether the decline in the fair value below the amortized cost basis (impairment) is due to credit-related factors or noncredit-related factors. Any impairment that is not credit related is recognized in other comprehensive income, net of applicable taxes. Credit-related impairment is recognized as an allowance for credit losses on the balance sheet, limited to the amount by which the amortized cost basis exceeds the fair value, with a corresponding adjustment to earnings. Both the allowance for credit losses and the adjustment to net income may be reversed if conditions change. However, if the Company intends to sell an impaired available for sale debt security or more likely than not will be required to sell such a security before recovering its amortized cost basis, the entire impairment amount is recognized in earnings with a corresponding adjustment to the security's amortized cost basis. In evaluating available for sale debt securities in unrealized loss positions for impairment and the criteria regarding its intent or requirement to sell such securities, the Company considers the extent to which fair value is less than amortized cost, whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred, and the results of reviews of the issuers' financial condition, among other factors. Changes in the allowance for credit losses are recorded as provision for (or reversal of) credit loss expense. Losses are charged against the ACL when management believes the uncollectability of an available for sale debt security is confirmed or when either of the criteria regarding intent or requirement to sell is met. No security credit losses were recognized during the years ended December 31, 2022, 2021 or 2020.

For HTM debt securities, the Company measures expected credit losses on held-to-maturity debt securities on a collective basis by major security type, then further disaggregated by sector and bond rating. Accrued interest receivable on held-to-maturity (HTM) debt securities is excluded from the estimate of credit losses. The estimate of expected credit losses considers historical credit loss information that is adjusted for current condition and reasonable and supportable forecasts based on current and expected changes in credit ratings and default rates. Based on the implied guarantees of the U. S. Government or its agencies related to certain of these HTM investment securities, and the absence of any historical or expected losses, substantially all qualify for a zero loss assumption. Management has separately evaluated its HTM investment securities from obligations of state and political subdivisions utilizing the historical loss data represented by similar securities over a period of time spanning nearly 50 years. As a result of this evaluation, management determined that the expected credit losses associated with these securities is not significant for financial reporting purposes and therefore, no allowance for credit losses has been recognized during the years ended December 31, 2022, 2021 or 2020.

Restricted Equity Securities

Restricted Equity Securities

Restricted equity securities represent the Company’s investment in the stock of the Federal Home Loan Bank of San Francisco (“FHLB”) and are carried at par value, which reasonably approximates its fair value. While technically these are considered equity securities, there is no market for the FHLB stock. Therefore, the shares are considered as restricted investment securities. Management periodically evaluates FHLB stock for other-than-temporary impairment. Management’s determination of whether these investments are impaired is based on its assessment of the ultimate recoverability of cost rather than by recognizing temporary declines in value. The determination of whether a decline affects the ultimate recoverability of cost is influenced by criteria such as (1) the significance of any decline in net assets of the FHLB as compared to the capital stock amount for the FHLB and the length of time this situation has persisted, (2) commitments by the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLB, (3) the impact of legislative and regulatory changes on institutions and, accordingly, the customer base of the FHLB, and (4) the liquidity position of the FHLB.

As a member of the FHLB system, the Bank is required to maintain a minimum level of investment in FHLB stock based on specific percentages of its outstanding mortgages, total assets, or FHLB advances. The Bank may request redemption at par value of any stock in excess of the minimum required investment. Stock redemptions are at the discretion of the FHLB. Both cash and stock dividends are reported as income when received.

Loans Held for Sale

Loans Held for Sale

Loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or fair value, as determined by aggregate outstanding commitments from investors of current investor yield requirements. Net unrealized losses are recognized through a valuation allowance by charges to non-interest income.

Mortgage loans held for sale are generally sold with the mortgage servicing rights retained by the Company. Gains or losses on the sale of loans that are held for sale are recognized at the time of the sale and determined by the difference between net sale proceeds and the net book value of the loans less the estimated fair value of any retained mortgage servicing rights.

Loans

Loans

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

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

Allowance for Credit Losses - Loans

Allowance for Credit Losses - Loans

The Company measures credit losses under ASU 2016-03 Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which replaced the incurred loss methodology, and is referred to as the current expected credit loss (CECL) methodology. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized costs, including loan receivables and held-to-maturity debt securities.

The allowance for credit losses (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 and U.S. gross domestic product.

A loan is considered to be collateral dependent when repayment is expected to be provided substantially through the operation or sale of the collateral. The ACL on collateral dependent loans is measured using the fair value of the underlying collateral, adjusted for costs to sell when applicable, less the amortized cost basis of the financial asset. If the value of underlying collateral is determined to be less than the recorded amount of the loan, a charge-off will be taken. Loans for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulties, is considered to be a troubled debt restructuring (TDR). The ACL on a TDR is measured using the same method as all other portfolio loans, except when the value of a concession cannot be measured using a method other than the discounted cash flow method. When the value of a concession is measured using the discounted cash flow method, the ACL is determined by discounting the expected future cash flows at the original interest rate of the loan.

PCD assets are assets acquired at a discount that is due, in part, to credit quality deterioration since origination which may be determined through observation of missed payments, downgrade in risk rating, deterioration of a borrower's financial trends or other observable factors including subjectivity utilized by management. PCD assets 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 consolidated balance sheets, while the allowance for acquired non-PCD assets, such as loans, is recorded through the provision for credit losses on the consolidated statements of income, 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 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 these 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.

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.

Real Estate Owned

Real Estate Owned

Real estate owned (REO) includes assets acquired through, or in lieu of, loan foreclosure. REO is held for sale and are initially recorded at fair value less estimated costs to sell at the date of acquisition, establishing a new cost basis. Physical possession of residential real estate property collateralizing a consumer mortgage loan occurs when legal title is obtained upon completion of foreclosure or when the borrower conveys all interest in the property to satisfy the loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Any write-downs based on the asset’s fair value less costs to sell at the date of acquisition are charged to the allowance for loan and lease losses. Any recoveries based on the asset’s fair value less estimated costs to sell in excess of the recorded value of the loan at the date of acquisition are recorded to the allowance for loan and lease losses. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. If fair value declines subsequent to foreclosure, a valuation allowance is recorded through expense. Operating costs after acquisition are expensed. Revenue and expenses from operations and changes in the valuation allowance are included in other non-interest expense, along with the gain or loss on sale of REO.

Premises and Equipment

Premises and Equipment

Land is carried at cost. Land improvements, buildings and equipment, including those acquired under capital lease, are stated at cost less accumulated depreciation and amortization. Depreciation and amortization expenses are computed using the straight-line method over the shorter of the estimated useful lives of the related assets or lease terms. Asset lives range from 3-10 years for furniture and equipment and 15-40 years for land improvements and buildings.

Company Owned Life Insurance

Company Owned Life Insurance

The Company has purchased life insurance policies on certain key executives. Company owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.

As a result of current tax law and the nature of these policies, the Bank records any increase in cash value of these policies as nontaxable non-interest income. If the Bank decided to surrender any of the policies prior to the death of the insured, such surrender may result in a tax expense related to the life-to-date cumulative increase in cash value of the policy. If the Bank retains such policies until the death of the insured, the Bank would receive nontaxable proceeds from the insurance company equal to the death benefit of the policies. The Bank has

entered into Joint Beneficiary Agreements (JBAs) with certain of the insured that provide some level of sharing of the death benefit, less the cash surrender value, among the Bank and the beneficiaries of the insured upon the receipt of death benefits.

Goodwill, Other Intangible and Long-Lived Assets

Goodwill, Other Intangible and Long-Lived Assets

Goodwill represents the excess of costs over fair value of net assets of businesses acquired from a business combination. The Company has an identifiable intangible asset consisting of core deposit intangibles (“CDI”). CDI are amortized over their respective estimated useful lives and reviewed periodically for impairment. Goodwill and other intangible assets acquired in a business combination and determined to have an indefinite useful life are not amortized, but instead tested for impairment at least annually. Other intangible assets with estimable useful lives are amortized over their respective estimated useful lives to their estimated residual values, and reviewed periodically for impairment.

As of September 30 of each year, goodwill is tested for impairment, and is tested for impairment more frequently if events and circumstances indicate that the asset might be impaired. An impairment loss is recognized to the extent that the carrying amount exceeds the asset’s fair value.

Long-lived assets, such as premises and equipment, and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of would be separately presented in the balance sheet and reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated. The assets and liabilities of a disposed group classified as held for sale would be presented separately in the appropriate asset and liability sections of the consolidated balance sheet.

Mortgage Servicing Rights

Mortgage Servicing Rights

Mortgage servicing rights (“MSR”) represent the Company’s right to a future stream of cash flows based upon the contractual servicing fee associated with servicing mortgage loans. Our MSR arise from residential and commercial mortgage loans that we originate and sell, but retain the right to service the loans. The net gain from the retention of the servicing right is included in gain on sale of loans in non-interest income when the loan is sold. Fair value is based on market prices for comparable mortgage servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, the custodial earnings rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses. Servicing fees, when earned, and changes in fair value of the MSR, are recorded in non-interest income.

The Company accounts for MSR at fair value. The determination of fair value of our MSR requires management judgment because they are not actively traded. The determination of fair value for MSR requires valuation processes which combine the use of discounted cash flow models and extensive analysis of current market data to arrive at an estimate of fair value. The cash flow and prepayment assumptions used in our discounted cash flow model are based on empirical data drawn from the historical performance of our MSR, which we believe are consistent with assumptions used by market participants valuing similar MSR, and from data obtained on the performance of similar MSR. The key assumptions used in the valuation of MSR include mortgage prepayment speeds and the discount rate. These variables can, and generally will, change from quarter to quarter as market conditions and projected interest rates change. The key risks inherent with MSR are prepayment speed and changes in interest rates.

Leases

Leases

The Company records a right-of-use asset (“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 is also required to record a lease liability on the consolidated balance sheets for the present value of future payment commitments. Substantially 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 twelve months or less) within the ROUA and lease liability. Known or determinable adjustments to the required minimum future lease payments are 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 are not unknown and not determinable at lease commencement and therefore, are 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. The Company uses 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.

Off-Balance Sheet Credit Related Financial Instruments

Off-Balance Sheet Credit Related Financial Instruments

In the ordinary course of business, the Company has entered into commitments to extend credit, including commitments under credit card arrangements, commercial letters of credit, and standby letters of credit. Such financial instruments are recorded when they are funded.

Low Income Housing Tax Credits

Low Income Housing Tax Credits

The Company accounts for low income housing tax credits and the related qualified affordable housing projects using the proportional amortization method. Under the proportional amortization method, the Company amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). Upon entering into a qualified affordable housing project, the Company records, in other liabilities, the entire amount that it has agreed to invest in the project, and an equal amount, in other assets, representing its investment in the project. As the Company disburses cash to satisfy its investment obligation, other liabilities are reduced. Over time, as the tax credits and other tax benefits of the project are realized by the Company, the investment recorded in other assets is reduced using the proportional amortization method.

Income Taxes

Income Taxes

The Company’s accounting for income taxes is based on an asset and liability approach. The Company recognizes the amount of taxes payable or refundable for the current year, and deferred tax assets and liabilities for the future tax consequences that have been recognized in its financial statements or tax returns. The measurement of tax assets and liabilities is based on the provisions of enacted tax laws. A valuation allowance, if needed, reduces deferred tax assets to the expected amount most likely to be realized. Realization of deferred tax assets is dependent upon the generation of a sufficient level of future taxable income and recoverable taxes paid in prior years. Although realization is not assured, management believes it is more likely than not that all of the deferred tax assets will be realized.

A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. Interest and/or penalties related to income taxes are reported as a component of non-interest income.

Share-Based Compensation

Share-Based Compensation

Compensation cost is recognized for stock options and restricted stock awards issued to employees and directors, based on the fair value of the awards at the date of grant. The estimate of the fair value of stock options and performance based restricted awards are based on a Black-Scholes or Monte Carlo model, respectively, while the market price of the common stock at the date of grant is used for time based restricted awards. Compensation cost is recognized over the required service period, generally defined as the vesting or measurement period. The Company’s accounting policy is to recognize forfeitures as they occur.

Earnings per Share

Earnings per Share

Basic earnings per share represents income available to common shareholders divided by the weighted-average number of common shares outstanding during the period. There are no unvested share-based payment awards that contain rights to nonforfeitable dividends (participating securities). Diluted earnings per share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustments to income that would result from assumed issuance. Potential common shares that may be issued by the Company relate solely from outstanding stock options and restricted stock units, and are determined using the treasury stock method.

Revenue Recognition

Revenue Recognition

The Company records revenue from contracts with customers in accordance with Accounting Standards Codification Topic 606, “Revenue from Contracts with Customers” (“Topic 606”). Under Topic 606, the Company must identify the contract with a customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract, and recognize revenue when (or as) the Company satisfies a performance obligation.

Most of our revenue-generating transactions are not subject to Topic 606, including revenue generated from financial instruments, such as our loans and investment securities. In addition, certain non-interest income streams such as fees associated with mortgage servicing rights, financial guarantees, derivatives, and certain credit card fees are also not in scope of the new guidance. The Company’s non-interest revenue streams are largely based on transactional activity, or standard month-end revenue accruals such as asset management fees based on month-end market values. Consideration is often received immediately or shortly after the Company satisfies its performance obligation and revenue is recognized. The Company does not typically enter into long-term revenue contracts with customers, and therefore, does not experience significant contract balances. As of December 31, 2022 and December 31, 2021, the Company did not have any significant contract balances. The Company has evaluated the nature of its revenue streams and determined that further disaggregation of revenue into more granular categories beyond what is presented in Note 18 was not necessary. The following are descriptions of revenues within the scope of ASC 606.

Deposit service charges

The Company earns fees from its deposit customers for account maintenance, transaction-based and overdraft services. Account maintenance fees consist primarily of account fees and analyzed account fees charged on deposit accounts on a monthly basis. The performance obligation is satisfied and the fees are recognized on a monthly basis as the service period is completed. Transaction-based fees on deposit accounts are charged to deposit customers for specific services provided to the customer, such as non-sufficient funds fees, overdraft fees, and wire fees. The performance obligation is completed as the transaction occurs and the fees are recognized at the time each specific service is provided to the customer.

Debit and ATM interchange fees

Debit and ATM interchange income represent fees earned when a debit card issued by the Company is used. The Company earns interchange fees from debit cardholder transactions through the Visa payment network. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder. The performance obligation is satisfied and the fees are earned when the cost of the transaction is charged to the cardholders’ debit card. Certain expenses directly associated with the credit and debit card are recorded on a net basis with the interchange income.

Commission on sale of non-deposit investment products

Commissions on sale of non-deposit investment products consist of fees earned from advisory asset management, trade execution and administrative fees from investments. Advisory asset management fees are variable, since they are based on the underlying portfolio value, which is subject to market conditions and asset flows. Advisory asset management fees are recognized quarterly and are based on the portfolio values at the end of each quarter. Brokerage accounts are charged commissions at the time of a transaction and the commission schedule is based upon the type of security and quantity. In addition, revenues are earned from selling insurance and annuity policies. The amount of revenue earned is determined by the value and type of each instrument sold and is recognized at the time the policy or contract is written.

Merchant fee income

Merchant fee income represents fees earned by the Company for card payment services provided to its merchant customers. The Company outsources these services to a third party to provide card payment services to these merchants. The third party provider passes the payments made by the merchants through to the Company. The Company, in turn, pays the third party provider for the services it provides to the merchants. These payments to the third party provider are recorded as expenses as a net reduction against fee income. In addition, a portion of the payment received represents interchange fees which are passed through to the card issuing bank. Income is primarily earned based on the dollar volume and number of transactions processed. The performance obligation is satisfied and the related fee is earned when each payment is accepted by the processing network.

Gain/loss on other real estate owned, net

The Company records a gain or loss from the sale of other real estate owned when control of the property transfers to the buyer, which generally occurs at the time of an executed deed of trust. When the Company finances the sale of other real estate owned to the buyer, the Company assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the other real estate owned asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on sale, the Company adjusts the transaction price and related gain or loss on sale if a significant financing component is present. Gains or losses from transactions associated with other real estate owned are recorded as a component of non-interest expense.

Accounting Standards Adopted in 2022 and Accounting Standards Pending Adoption

Accounting Standards Adopted in 2022

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This ASU provides temporary optional guidance to ease the potential burden in accounting for reference rate reform by providing optional expedients and exceptions for applying generally accepted accounting principles (GAAP) to contracts, hedging relationships, and other transactions affected if certain criteria are met. At the time that Update 2020-04 was issued, the UK Financial

Conduct Authority (FCA) had established its intent that it would no longer be necessary to persuade, or compel, banks to submit to LIBOR after December 31, 2021. As a result, the sunset provision was set for December 31, 2022—12 months after the expected cessation date of all currencies and tenors of LIBOR. In March 2021, the FCA announced that the intended cessation date of the overnight 1-, 3-, 6-, and 12-month tenors of USD LIBOR would be June 30, 2023, which is beyond the current sunset date of Topic 848. Because the current relief in Topic 848 may not cover a period of time during which a significant number of modifications may take place, the amendments in this

Update defer the sunset date of Topic 848 from December 31, 2022, to December 31, 2024. As the Company has an insignificant number of instruments that are applicable to this ASU, management has determined that no impact to the valuations of these instruments are applicable for financial reporting purposes.

Accounting Standards Pending Adoption

In March 2022, the FASB issued ASU 2022-02, Financial Instruments — Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. The amendments in this Update eliminate the TDR recognition and measurement guidance and, instead, require that an entity evaluate (consistent with the accounting for other loan modifications) whether the modification represents a new loan or a continuation of an existing loan. The amendments enhance existing disclosure requirements and introduce new requirements related to certain modifications of receivables made to borrowers experiencing financial difficulty. Furthermore, the amendments in this Update require that an entity disclose current-period gross write-offs by year of origination for financing receivables and net investment in leases within the scope of Subtopic 326-20. The Company adopted these amendments on January 1, 2023 and has thus far observed no material impact to

deferred fees and costs and the related timing of net interest income recognition as a result of adoption.
