Merger Update

On March 25, 2022, the Company completed its acquisition of Valley Republic Bancorp, including the merger of Valley Republic Bank (collectively "VRB") 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 for the settlement of stock option awards at VRB.

As a result of the merger with VRB, the Company acquired assets consisting primarily of cash totaling $427.3 million, investment securities of $109.7 million, loans totaling $771.4 million (inclusive of $21.4 million in PPP and fair value discounts of $20.4 million), core deposit intangibles of $10.7 million, and liabilities consisting primarily of $1.2 billion in deposits and $47.3 million in subordinated debt (of which $4.4 million was retired as TriCo Bancshares was the counter party).

VRB was headquartered in Bakersfield, California, and had four branch locations in and around Bakersfield, which all now operate as branches for Tri Counties Bank, and a loan production office in Fresno, California. The Company anticipates that Tri Counties Bank's previously existing Bakersfield branch and the VRB loan production office in Fresno will be consolidated, subject to regulatory approval, into the overlapping locations in the near future.

Balance Sheet

Total loans outstanding, excluding PPP, grew to $5.80 billion as of March 31, 2022, an increase of 25.8% over the prior year, of which 9.5% was related to organic loan growth. Investments increased to $2.57 billion as of March 31, 2022, an increase of 30.9% annualized over the prior year. Average earning assets to total average assets remained flat at 92.9% at March 31, 2022, as compared to 93.0% and 92.7% at December 31, 2021, and March 31, 2021, respectively. The loan to deposit ratio was 67.2% at March 31, 2022, as compared to 66.7% and 72.4% at December 31, 2021, and March 31, 2021, respectively.

Total shareholders' equity increased by $108,998,000 during the quarter ended March 31, 2022, as a result of issuing $173,585,000 in common stock associated with the VRB merger and net income of $20,374,000, which was partially offset by a decrease in accumulated other comprehensive income of $78,339,000 and $7,433,000 in cash dividends paid on common stock. As a result, the Company’s book value was $32.78 per share at March 31, 2022 as compared to $33.64 and $31.71 at December 31, 2021, and March 31, 2021, respectively.

Organic loan growth, excluding PPP, of $187,915,000 or 15.5% on an annualized basis was realized during the quarter ended March 31, 2022, primarily within commercial real estate and commercial and industrial. In addition, investment security organic growth was $32,105,000 or 5.3% on an annualized basis as excess liquidity, driven by continued strong deposit growth, was put to use in higher yielding earning assets. Deposit balances continue to increase, with an organic change of $131,839,000 or 7.2% annualized during the period, which provides management with opportunities to deploy excess cash within the investment portfolio or other interest earnings assets. During the three months ended March 31, 2022 and excluding PPP balance changes, loan originations totaled approximately $396 million while payoffs of loans totaled $225 million which compares to origination and payoff activity during the three months ended December 31, 2021 of $412 million and $297 million, respectively. Investment securities increased to $2,569,706,000 at March 31, 2022, an organic change of $497,210,000 or 25.3% from the prior year.

PPP loan balances outstanding, net of related deferred fees, have declined by $304,239,000 during the twelve months ended March 31, 2022, meanwhile, non-PPP loan balances have increased as a result of organic activities by approximately $437,259,000 during the same period. This has led to a long-term beneficial and meaningful shift in the makeup of the loan portfolio, despite total loan balances increasing modestly during the 12 month period ended March 31, 2022, by $111,608,000 or 2.2%. The Company's non-

PPP loan originations have increased significantly over the past year but have also been challenged by an acceleration in payoffs. Specifically, during the twelve months ended March 31, 2022 and excluding PPP balance changes, loan originations totaled approximately $1.40 billion while payoffs of loans totaled $0.91 billion. Investment securities increased to $2,569,706,000 at March 31, 2022, an organic change of $497,210,000 or 25.3% from the prior year.

Loans may be acquired at a premium or discount to par value, in which case, the premium is amortized (subtracted from) or the discount is accreted (added to) interest income over the remaining life of the loan. Generally, as time goes on, the dollar impact of loan discount accretion and loan premium amortization decrease as the purchased loans mature or pay off early. Upon the early pay off of a loan, any remaining unaccreted discount or unamortized premium is immediately taken into interest income; and as loan payoffs may vary significantly from quarter to quarter, so may the impact of discount accretion and premium amortization on interest income. As a result of the increase in interest rates, the prepayment rate of portfolio loans, inclusive of those acquired at a premium or discount, declined during the first quarter of 2022. During the three months ended March 31, 2022, December 31, 2021, and March 31, 2021, purchased loan discount accretion was $1,323,000, $1,780,000, and $1,712,000, respectively.

(2)Net interest spread is the average yield earned on interest-earning assets minus the average rate paid on interest-bearing liabilities.

(3)Net interest margin is computed by calculating the difference between interest income and interest expense, divided by the average balance of interest-earning assets.

Net interest income (FTE) during the three months ended March 31, 2022 decreased $1,850,000 or 2.6% to $68,207,000 compared to $70,057,000 during the three months ended December 31, 2021. Over the same period, net interest margin declined 11 basis points to 3.39%, as compared to the trailing quarter. The decline in net interest income is attributed to a reduction of $2,997,000 in the revenues recognized from PPP loans, partially offset by increases in average volume and rates on investment securities which increased interest income by $1,234,000 over the trailing quarter.

As compared to the same quarter in the prior year, average loan yields, excluding PPP, decreased 37 basis points from 5.02% during the three months ended March 31, 2021, to 4.65% during the three months ended March 31, 2022. The accretion of discounts from acquired loans added 7 and 10 basis points to loan yields during the quarters ended March 31, 2022 and March 31, 2021, respectively. Therefore, of the 37 basis point decrease in yields on loans during the comparable three month periods ended March 31, 2022 and 2021, 34 basis points was attributable to decreases in market rates, while 3 basis points resulted from less accretion of discounts.

The rates paid on interest bearing liabilities generally remained flat during the quarter ended March 31, 2022 compared to the trailing quarter. The decline in interest expense when compared to the same quarter from the prior year, however, was primarily attributed to reductions in the rates offered on deposit products. As a result, the cost of interest-bearing deposits decreased by 4 basis points during the quarter ended March 31, 2022, to 0.06% from 0.10% during the same quarter of the prior year. In addition, the level of noninterest-bearing deposits continues to benefit the average cost of total deposits which remained flat at 0.04% in both the current and trailing quarter, compared to 0.6% in the first quarter of the prior year. Specifically, the ratio of average total noninterest-bearing deposits to total average deposits was 40.6% and 40.5% as of March 31, 2022 and December 31, 2021, respectively, as compared to 39.9% for the quarter ended March 31, 2021.

Interest Rates and Loan Portfolio Composition

During the quarter ended March 31, 2022, market interest rates, including many rates that serve as reference indices for variable rate loans, increased modestly. However, the loan portfolio yield continues to have a downward bias due to the repricing of loans at lower rates and increased market competition stemming from loan to deposit ratios being at historic lows. As of March 31, 2022, the Company's loan portfolio consisted of approximately $5.9 billion in outstanding principal with a weighted average coupon rate of 4.24%, inclusive of the PPP program loans. Excluding PPP loans, the Company's loan portfolio has approximately $5.8 billion outstanding with a weighted average coupon rate of 4.27% as of March 31, 2022. Included in the March 31, 2022 loan total, exclusive of PPP loans, are variable rate loans totaling $3.4 billion, of which, $800 million are considered floating based on the Wall Street Prime index.

Asset Quality and Credit Loss Provisioning

During the three months ended March 31, 2022, the Company recorded a provision for credit losses of $8,330,000, as compared to a $980,000 provision during the trailing quarter, and a reversal of provision expense of $6,060,000 during the first quarter of 2021.

The following table presents details of the provision for credit losses for the periods indicated:

	Three months ended

The following table presents the activity in the allowance for credit losses on loans for the periods indicated:

	Three months ended
(dollars in thousands)	March 31, 2022		March 31, 2021

Loans charged-off	(743)		(226)
Recoveries of previously charged-off loans	1,174		560
Balance, end of period	$	96,049	$	85,941

The allowance for credit losses (ACL) was $96,049,000 as of March 31, 2022, a net increase of $10,108,000 over the immediately preceding quarter. The provision for credit losses of $8,205,000 during the quarter was the net effect of increases in required reserves totaling $10,820,000 related to the loan portfolio acquired from VRB totaling $703,848,000, which is net of $68,513,000 in purchase credit deteriorated loans (PCD) and $21,412,000 in PPP loans as of the merger date, partially offset by a decline in required reserves from the Company's organic loan portfolio totaling $2,615,000.

Purchased loans and leases that reflect a more-than-insignificant deterioration of credit from origination are considered PCD. For PCD loans and leases, the initial estimate of expected credit losses is recognized in the ACL on the date of acquisition using both a discounted cash flow model, and the same methodology as other loans and leases held-for-investment. The ACL recorded as of the VRB merger date for PCD loans totaled $2,037,000.

The Company utilizes a forecast period of approximately eight quarters and obtains the forecast data from publicly available sources as of the balance sheet date. This forecast data continues to evolve and included improving shifts in the magnitude of changes for both the unemployment and GDP factors leading up to the balance sheet date, particularly CA unemployment trends. However, management notes that the majority of economic forecasts utilized in the ACL calculation have remained directionally consistent with preceding quarters, as general economic conditions continue to improve, albeit at a pace slower than expected due to unforeseen disruptions in the supply chain and increasing energy prices. In addition, management notes that the actual and forecast increases in inflation that were previously identified by the Federal Reserve Board as "transitory", combined with overseas conflicts and leading to

the likely rise in short-term interest rates and flattening or inversion of the yield curve, may be further indication of future economic contraction. 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.

Loans past due 30 days or more decreased by $4,070,000 during the quarter ended March 31, 2022 to $8,402,000, as compared to $4,332,000 at December 31, 2021. Non-performing loans were $14,088,000 at March 31, 2022, a decrease of $16,262,000 and $14,853,000 from $30,350,000 and $28,941,000 as of December 31, 2021 and March 31, 2021, respectively.

The following table illustrates the total loans by risk rating and their respective percentage of total loans for the periods presented.

	March 31,			% of Total Loans		December 31,			% of Total Loans		March 31			% of Total Loans

Loans past due 30+ days to total loans	0.14		%			0.09		%			0.21		%

The ratio of classified loans to total loans improved to 0.84% as of March 31, 2022 as compared to both 1.06% and 1.17% for the trailing quarter and same quarter of the prior year, respectively. The Company's criticized loan balances increased during the current quarter by approximately $40,402,000 to $169,949,000 as of March 31, 2022, primarily from the merger with VRB which added approximately $65,556,000 in criticized loans, net of $2,957,000 in purchase discounts. All of the criticized loans acquired from VRB were identified by management as PCD as of the acquisition date. The Company's organic criticized loan balances outstanding improved by approximately $19,100,000 during the quarter ended March 31, 2022, the majority of which was attributed to a sale of substandard loans totaling approximately $12,043,000.

There was one property added to other real estate owned totaling $313,000 during the quarter ended March 31, 2022, and no disposals. As of March 31, 2022, other real estate owned consisted of seven properties with a carrying value of approximately $2,907,000.

Non-performing assets of $16,995,000 at March 31, 2022 represented 0.17% of total assets, a substantial decrease from the $32,944,000 or 0.38% and $31,250,000 or 0.39% as of December 31, 2021 and March 31, 2021, respectively. The improvement in non-performing assets relates primarily to the loan sale discussed above.

For the periods presented in the table above and for purposes of calculating the "% of Loans Outstanding", PPP loans are included in the segment "Commercial and Industrial." PPP loans are fully guaranteed and therefore would not require any loss reserve allocation. Excluding the net outstanding balances of PPP loans from the ratio of the ACL to total loans results in a reserve ratio of approximately 1.66% as of March 31, 2022. In addition to the allowance for credit losses above, the Company has acquired various performing loans whose fair value as of the acquisition date was determined to be less than the principal balance owed on those loans. This difference represents the collective discount of credit, interest rate and liquidity measurements which is expected to be amortized over the life of the loans. As of March 31, 2022, the unamortized discount associated with acquired loans totaled $34,908,000 and, if aggregated with the ACL, would collectively represent 2.22% of total gross loans and 2.26% of total loans less PPP loans.

SBA Paycheck Protection Program

In March 2020 (Round 1) and subsequently in December 2020 (Round 2), the Small Business Administration ("SBA") Paycheck Protection Program ("PPP") was created to help small businesses keep workers employed during the COVID-19 crisis. Tri Counties Bank, through its online portal, facilitated the ability for borrowers to open a new deposit account and submit PPP applications during the entirety of the Programs. The SBA ended PPP and did not accept new borrowing applications, effective May 31, 2021. The following is a summary of PPP loan related information as of the periods indicated:

(dollars in thousands)	March 31, 2022		December 31, 2021		March 31, 2021
Total number of PPP loans outstanding	243		450		2,484

PPP deferred loan fees (Round 2 origination)	1,190		2,163		7,072
Total PPP deferred loan fees (costs) outstanding	$	1,190	$	2,164	$	9,430

As of March 31, 2022, there was approximately $1,190,000 in net deferred fee income remaining to be recognized. During the three months ended March 31, 2022, the Company recognized $974,000 in fees on PPP loans as compared with $3,482,000 and $4,978,000 for the three months ended December 31, 2021 and March 31, 2021, respectively. Based on the payment guarantee provided by the SBA as well as the expected short-term duration of the PPP loans acquired from VRB, the fair value of these loans approximates the principal balance outstanding as of the merger date, and therefore, no purchase discount was recorded.

Non-interest income decreased $1,406,000 or 8.5% to $15,096,000 during the three months ended March 31, 2022, compared to $16,502,000 during the quarter ended December 31, 2021. This was largely the result of two items recorded within other non-interest income during the trailing quarter which included, death benefits on life insurance totaling $702,000 and an increase in the fair value of certain equity investments of approximately $804,000 as compared to $225,000 in the current quarter. In addition, a gain on debt extinguishment of $235,000 was recorded in the current quarter. The change in gain on sale of mortgage loans declined by $426,000 or 25.5% during the quarter ended March 31, 2022, with an offset in the change in value or mortgage servicing rights increasing by $455,000 or 251.4%, both attributed to the rapidly rising rate environment.

Non-interest expense for the quarter ended March 31, 2022 decreased $232,000 or 0.5% to $46,447,000 as compared to $46,679,000 during the trailing quarter ended December 31, 2021. Total salaries and benefits expense decreased by $895,000 or 3.2%, led by wage related decreases of $907,000 or 4.7% to $18,216,000, despite an increase of 10 full-time equivalent positions. As disclosed previously, the trailing quarter wage was elevated partially due to transitory items caused by the COVID-19 pandemic, overtime and non-incentive stipends associated with special projects that did not persist into the three months ended March 31, 2022. Incentive compensation decreased $1,349,000 or 34.3%, attributed to lower commissions and incentive accruals on loan origination activities; meanwhile, benefits and other compensation costs increased by $1,361,000 or 29.5%, respectively, during the quarter ended March 31, 2022, due to the expected seasonal impacts associated with the start of any new fiscal year as well as increases in expenses associated with projected benefit obligations and group insurance costs. Merger and acquisition expenses associated with the merger with Valley Republic Bancorp totaled $4,032,000 during the current quarter. The Company sold a former administrative building and relocated a branch during the quarter resulting in a net gain of approximately $1,078,000 as noted above.

Provision for Income Taxes

The Company’s effective tax rate was 27.9% for the three months ended March 31, 2022, as compared to 28.1% for the year ended December 31, 2021. Differences between the Company's effective tax rate and applicable federal and state blended statutory rate of approximately 29.6% are due to the proportion of non-taxable revenues, non-deductible expenses, and benefits from tax credits as compared to the levels of pre-tax earnings.

Forward-Looking Statement

The statements contained herein that are not historical facts are forward-looking statements based on management’s current expectations and beliefs concerning future developments and their potential effects on the Company. Such statements involve inherent risks and uncertainties, many of which are difficult to predict and are generally beyond our control. 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 on the Company's business condition and financial operating results; the impact of changes in financial services policies, laws and regulations; technological changes; weather, natural disasters and other catastrophic events that may or may not be caused by climate change and their effects on economic and business environments in which the Company operates; the continuing adverse impact on the U.S. economy, including the markets in which we operate due to the COVID-19 global pandemic, and 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, inflationary pressures and labor shortages on the economic recovery and our business; the impacts of international hostilities or geopolitical events; the costs or effects of mergers, acquisitions or dispositions we may make, whether we are able to obtain any required governmental approvals in connection with any such mergers, acquisitions or dispositions, and/or our ability to 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 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 of our nonperforming assets and charge-offs; the appropriateness of the allowance for credit losses, including the timing and effects of the implementation of the current expected credit losses model; any deterioration in values of California real estate, both residential and commercial; the effect of changes in accounting standards and practices; possible other-than-temporary impairment of securities held by us; changes in consumer spending, borrowing and savings habits; our ability to attract and maintain deposits and other sources of liquidity; changes in the financial performance and/or condition of our borrowers; 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 integrating and retaining key employees; the costs and effects of litigation and of unexpected or adverse outcomes in such litigation; a failure in or breach of our operational or security systems or infrastructure, or those of our third-party vendors or other service providers, including as a result of cyber-attacks and the cost to defend against such attacks; change to U.S. tax policies, including our effective income tax rate; the effect of a fall in stock market prices on our brokerage and wealth management businesses; the discontinuation of the London Interbank Offered Rate and other reference rates; and our ability to manage the risks involved in the foregoing. Additional factors that could cause results to differ materially from those described above can be found in our Annual Report on Form 10-K for the year ended December 31, 2021, which has been filed with the Securities and Exchange Commission (the “SEC”) and are available in the “Investor Relations” section of our website, https://www.tcbk.com/investor-relations and in other documents we file with the SEC.

TRICO BANCSHARES—NON-GAAP FINANCIAL MEASURES

(Unaudited. Dollars in thousands)

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