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 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)	September 30, 2021		June 30, 2021		March 31, 2021		December 31, 2020		September 30, 2020

Total PPP deferred loan fees outstanding	$	6,013	$	8,990	$	9,430	$	7,212	$	11,846

As of September 30, 2021, the total gross balance outstanding of PPP loans was $157,461,000 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 September 30, 2021, there was approximately $6,013,000 in net deferred fee income remaining to be recognized. During the three and nine months ended September 30, 2021, the Company recognized $2,984,000 and $10,306,000, respectively in fees on PPP loans as compared with $2,603,000 and $4,959,000 for the three and nine months ended September 30, 2020, respectively.

COVID Deferrals

Following the passage of the CARES Act legislation, the "Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus" was issued by federal bank regulators, which offers temporary relief from troubled debt restructuring accounting for loan payment deferrals for certain customers whose businesses are experiencing economic hardship due to Coronavirus. The applicable period for this relief, originally expected to expire on December 31, 2020, was extended through 2021 by way of the Consolidated Appropriations Act.

The following is a summary of COVID related loan customer modifications with outstanding balances as of September 30, 2021:

					Modification Type				Deferral Term
(dollars in thousands)	Modified Loan Balances Outstanding		% of Total Category of Loans		Interest Only Deferral		Principal and Interest Deferral		90 Days		180 Days		Other
Commercial real estate:
CRE non-owner occupied	$	22,264	1.5	%	100.0	%	—	%	17.4	%	65.6	%	17.0	%

Total modifications	$	24,057	0.5	%	100.0	%	—	%	16.1	%	60.8	%	23.1	%

Of the remaining balance outstanding as of September 30, 2021, $5,665,000 is related to second deferrals which are expected to conclude their modification period during 2021, and the remainder of deferrals are expected to conclude in the first quarter of 2022. However, as long as the current pandemic and recessionary economic conditions continue, it is possible that additional borrowers may request an initial or subsequent modification to their loan terms.

Balance Sheet

Total loans outstanding, excluding PPP, grew to $4.74 billion as of September 30, 2021, an increase of 7.6% over the same quarter of the prior year, and an annualized increase of 2.6% over the trailing quarter. Investments outstanding increased to $2.33 billion as of September 30, 2021, an increase of 43.6% annualized over the trailing quarter. Average earning assets to total average assets continued to increase to 92.9% at September 30, 2021, as compared to 92.8% and 92.3% at June 30, 2021, and September 30, 2020, respectively.

Total shareholders' equity increased by $15,234,000 during the quarter ended September 30, 2021, primarily as a result of net income of $27,422,000, offset by a decrease in accumulated other comprehensive income of $4,440,000, and $7,429,000 in cash dividends paid on common stock. As a result, the Company’s book value increased to $33.05 per share at September 30, 2021 as compared to $32.53 and $30.31 at June 30, 2021, and September 30, 2020, respectively. The Company’s tangible book value per share, a non-GAAP measure, calculated by subtracting goodwill and other intangible assets from total shareholders’ equity and dividing that sum by total shares outstanding, was $25.16 per share at September 30, 2021, as compared to $24.60 and $22.24 at June 30, 2021, and September 30, 2020, respectively.

Trailing Quarter Balance Sheet Change

Ending balances	As of September 30,		June 30,		$ Change		Annualized  % Change
(dollars in thousands)	2021		2021
Total assets	$	8,458,030	$	8,170,365	$	287,665	14.1	%
Total loans	4,887,496		4,944,894		(57,398)		(4.6)	%
Total loans, excluding PPP	4,736,048		4,705,302		30,746		2.6	%
Total investments	2,333,015		2,103,575		229,440		43.6	%
Total deposits	$	7,236,822	$	6,992,053	$	244,769	14.0	%

Organic loan growth, excluding PPP, of $30,746,000 or 2.6% on an annualized basis was realized during the quarter ended September 30, 2021, primarily within commercial real estate. In addition, investment security growth was $229,440,000 or 43.6% on an annualized basis as excess liquidity, driven by continued strong deposit growth, was put to use in higher yielding earning assets. Earning asset growth was funded by the continued growth of deposit balances which increased during the third quarter of 2021 by $244,769,000 or 14.0% annualized.

Average Trailing Quarter Balance Sheet Change

Qtrly avg balances for the period ended	September 30,		June 30,		$ Change		Annualized  % Change
(dollars in thousands)	2021		2021
Total assets	$	8,348,111	$	8,128,674	$	219,437	10.8	%
Total loans	4,897,922		4,978,465		(80,543)		(6.5)	%
Total loans, excluding PPP	4,684,492		4,646,188		38,304		3.3	%
Total investments	2,149,311		2,007,090		142,221		28.3	%
Total deposits	$	7,137,263	$	6,943,081	$	194,182	11.2	%

The decrease in average total loans of $80,543,000, or (6.5)% on an annualized basis, during the third quarter of 2021 was led by the quarter over quarter decline in net PPP loan balances outstanding totaling $88,144,000. As noted above, the significant growth in both ending and average balances of investment securities was a direct result of management's focus on the deployment of excess cash balances which remained elevated due to continued deposit growth during the quarter.

Year Over Year Balance Sheet Change

Ending balances	As of September 30,
(dollars in thousands)	2021		2020		$ Change		% Change
Total assets	$	8,458,030	$	7,449,799	$	1,008,231	13.5	%
Total loans	4,887,496		4,826,338		61,158		1.3	%
Total loans, excluding PPP	4,736,048		4,400,390		335,658		7.6	%
Total investments	2,333,015		1,473,935		859,080		58.3	%
Total deposits	$	7,236,822	$	6,340,588	$	896,234	14.1	%

Net PPP loan balances outstanding have declined by $274,499,000 during the twelve months ended September 30, 2021, meanwhile, non-PPP loan balances (both organic and purchased) have increased by $335,658,000 during the same period. This has led to a beneficial and meaningful shift in the makeup of the loan portfolio, despite total loan balances increasing modestly between September 30, 2021 and September 30, 2020, by $61,158,000 or 1.3%. The Company's organic loan production originations have increased meaningfully over the past year but have also been challenged by an acceleration in payoffs. Specifically, during the twelve months ended September 30, 2021 and September 30, 2020 organic loan originations totaled approximately $1.16 billion and $0.89 billion, respectively; while payoffs of loans totaled $0.84 billion and $0.60 billion, respectively. While pipelines continue to grow, loan originations of $4,086,000 relate to the Company's recently opened loan production offices. Investment securities increased to $2,333,015,000 at September 30, 2021, a change of $859,080,000 or 58.3% from $1,473,935,000 at September 30, 2020.

(1)Certain information included herein is presented on a fully tax-equivalent (FTE) basis and / or to present additional financial details which may be desired by users of this financial information. The Company believes the use of these non-generally accepted accounting principles (non-GAAP) measures provide additional clarity in assessing its results, and the presentation of these measures are common practice within the banking industry. See additional information related to non-GAAP measures at the back of this document.

Loans may be acquired at a premium or discount to par value, in which case, the premium is amortized (subtracted from) or 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 third quarter of 2021. During the three months ended September 30, 2021, June 30, 2021, and September 30, 2020, purchased loan discount accretion was $2,034,000, $2,566,000, and $1,876,000, respectively.

Net interest income (FTE) during the three months ended September 30, 2021 increased $1,160,000 or 1.7% to $68,498,000 compared to $67,338,000 during the three months ended June 30, 2021. Over the same period, net interest margin decreased 8 basis points to 3.50% as compared to 3.58% in the trailing quarter. The 8 basis point decrease coincides with, and is primarily attributed to, an 8 basis point decrease in non-PPP loan yields. The remaining segments of quarter over quarter changes in yields largely offset each

6

other, which included a 268 basis point improvement in PPP loans to 6.52% at September 30, 2021 from 3.84% at June 30, 2021, attributed to an acceleration of deferred fee accretion stemming from Round 2 PPP loans being forgiven by the SBA and repaid.

As compared to the same quarter in the prior year, average loan yields, excluding PPP, decreased 17 basis points from 5.02% during the three months ended September 30, 2020, to 4.85% during the three months ended September 30, 2021. The accretion of discounts from acquired loans added 17 basis points to loan yields during both quarters ended September 30, 2021 and September 30, 2020. Therefore, the 17 basis point decrease in yields on loans during the comparable three month periods ended September 30, 2021 and 2020 was entirely attributable to decreases in market rates. The index utilized in a significant portion of the Company’s variable rate loans, Wall Street Journal Prime, has remained unchanged at 3.25% since March 15, 2020, when it was reduced from 4.25%.

The rates paid on interest bearing liabilities generally remained flat during the quarter ended September 30, 2021 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 7 basis points as of September 30, 2021, to 0.08% from 0.15% at September 30, 2020. In addition, the growth of noninterest-bearing deposits continues to benefit the average cost of total deposits as compared to historical periods. Specifically, the ratio of average total noninterest-bearing deposits to total average deposits was 40.6% and 40.5% as of September 30, 2021 and June 30, 2021, respectively, as compared to 39.4% in the quarter ended September 30, 2020. As a result, the average cost of total deposits decreased to 0.05% at September 30, 2021, compared to 0.09% in the same period of 2020.

Interest Rates and Loan Portfolio Composition

During the quarter ended September 30, 2021, market interest rates, including many rates that serve as reference indices for variable rate loans, improved 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 at historic lows. As of September 30, 2021, the Company's loan portfolio consisted of approximately $4.9 billion in outstanding principal with a weighted average coupon rate of 4.28%, inclusive of the PPP program loans. Excluding PPP loans, the Company's loan portfolio has approximately $4.8 billion outstanding with a weighted average coupon rate of 4.38% as of September 30, 2021. Included in the September 30, 2021 loan total, exclusive of PPP loans, are variable rate loans totaling $3.0 billion of which 88.5% or $2.7 billion were at their floor rate. The remaining variable rate loans totaling $351.0 million, which carried a weighted average coupon rate of 4.78% as of September 30, 2021, are subject to further rate adjustment. If those remaining variable rate loans were to collectively, through future rate adjustments, be reduced to their respective floors, they would have a weighted average coupon rate of approximately 4.25% which would result in the reduction of the weighted average coupon rate of the total loan portfolio, exclusive of PPP loans, from 4.38% to approximately 4.30%.

As of December 31, 2020, the Company's loan portfolio consisted of approximately $4.80 billion in outstanding principal with a weighted average coupon rate of 4.35%, inclusive of the PPP program loans. Excluding PPP loans, the Company's loan portfolio has approximately $4.47 billion outstanding with a weighted average coupon rate of 4.60% as of December 31, 2020. Included in the December 31, 2020 loan total, exclusive of PPP loans, are variable rate loans totaling $3.02 billion of which 88.2% or $2.66 billion were at their floor rate. The remaining variable rate loans totaling $357.0 million, which carried a weighted average coupon rate of 5.03% as of December 31, 2020, are subject to further rate adjustment. If those remaining variable rate loans were to collectively, through future rate adjustments, be reduced to their respective floors, they would have a weighted average coupon rate of approximately 4.36% which would result in the reduction of the weighted average coupon rate of the total loan portfolio, exclusive of PPP loans, from 4.60% to approximately 4.55%.

Asset Quality and Credit Loss Provisioning

During the three months ended September 30, 2021, the Company recorded a reversal of provision for credit losses of $1,435,000, as compared to a reversal of provision for credit losses of $260,000 during the trailing quarter, and a provision expense of $7,649,000 during the third quarter of 2020.

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

The allowance for credit losses (ACL) was $84,306,000 as of September 30, 2021, a net decrease of $1,756,000 over the immediately preceding quarter. The reversal of allowance for credit losses of $1,495,000 was necessary as net charge-offs totaling $261,000 during the quarter were less than the required changes in quantitative and qualitative reserve components. More specifically, the quantitative reserve required under the cohort model reduced required reserves by $1,762,000, in addition to a decrease in specific reserves on impaired totals of $874,000 as of quarter end.

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

8

the unemployment and GDP factors leading up to the balance sheet date. 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 level of governmental assistance provided through PPP as well as other programs during the last several quarters has been unprecedented. 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 a reserve level that incorporates such risk factors.

Loans past due 30 days or more increased by $1,247,000 during the quarter ended September 30, 2021 to $10,539,000, as compared to $9,292,000 at June 30, 2021. Non-performing loans were $28,790,000 at September 30, 2021, a decrease of $3,915,000 and $5,827,000, respectively, from $32,705,000 and $22,963,000 as of June 30, 2021, and September 30, 2020, respectively.

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

The Company's loan portfolio for non-classified loans (loans graded special mention or better) remains consistent for the quarter ended September 30, 2021, as compared to the trailing quarter June 30, 2021, representing 99.0% and 98.8% of total loans outstanding, respectively. Loans risk graded special mention increased by approximately $8,466,000 during the current quarter as compared to the trailing quarter, while loans risk graded substandard decreased by $8,047,000 over the same period.

There was one addition to other real estate owned totaling $560,000, including a $113,000 fair value benefit, during the quarter ended September 30, 2021 and there was one sale for approximately $189,000, which generated a net gain of $31,000 for the quarter. As of September 30, 2021, other real estate owned consisted of six properties with a carrying value of approximately $2,650,000.

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 1.78% as of September 30, 2021. 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

9

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 September 30, 2021, the unamortized discount associated with acquired loans totaled $17,984,000 and, if aggregated with the ACL, would collectively represent 2.09% of total gross loans and 2.16% of total loans less PPP loans.

Non-interest income decreased $862,000 or 5.4% to $15,095,000 during the three months ended September 30, 2021, compared to $15,957,000 during the trailing quarter June 30, 2021. Gain on sale of mortgage loans declined by $1,033,000 or 36.3% during the recent quarter ended, as interest rates continued to trend higher, contributing to the decline in total mortgage origination and refinance activity during the three months ended September 30, 2021. Changes in ATM and interchange fees as well as service charges were a direct result of changes in usage and depositor requested services.

Changes in the value of mortgage servicing rights and gain on sale of mortgage loans declined by $468,000 and $1,221,000, respectively, related to the aforementioned interest rate increases during the most recent two quarters. Included in other non-interest income for the three months ended September 30, 2021 and 2020 are earnings (losses) from the changes in fair value of acquired deferred compensation plans of $23,000 and ($241,000), respectively.

Merger and acquisition expenses of $651,000 were recorded during the quarter in connection with the merger agreement with Valley Republic Bancorp entered on July 27, 2021. A non-recurring gain on disposal of fixed assets related to the sale of a former branch totaling $426,000 was recorded during the trailing quarter. Additionally, as a result of various event postponements that resulted from COVID distancing requirements as well as normal seasonality in not-for-profit event sponsorships, expenses associated with these activities fluctuated significantly between periods and were $203,000, $3,000, and $386,000 in each of the first three quarters of 2021 and $124,000 in the third quarter of 2020 and are included in other

miscellaneous expenses. As a partial offset, total salaries and benefits expense declined by $807,000 or 3.0%, led by incentive compensation declines of $1,199,000 or 27.7% to $3,123,000 during the quarter ended September 30, 2021 as compared to the trailing period. Costs associated with the Company's recently opened loan production offices, inclusive of salaries, benefits and occupancy, totaled approximately $710,000 during the third quarter and $235,000 in the second quarter.

The comparative period in 2020 included approximately $400,000 in non-recurring severance costs from reductions in personnel and a reduction of nearly $745,000 in deferred loan origination costs following a taper of the first round of PPP loan origination volume. Benefits and other compensation expense decreased by $2,905,000 during the three months ended September 30, 2021, primarily the result of decreases in expenses associated with retirement obligations and group insurance costs. Approximately $95,000 of the increase in occupancy expense is attributable to the Company's recently opened loan production offices.

The changes in non-interest expense for the nine months ended September 30, 2021 and 2020 are generally consistent with the changes in the comparable three month periods discussed above. During the nine months ended September 30, 2021, approximately $944,000 is attributable to the Company's recently opened loan production offices, of which approximately $824,000 relates to salaries and benefits. Regulatory assessment and insurance expense increased in the current year to date period primarily due to the expiration of credits during the 2020 year and to a lesser extent, the overall balance sheet growth of the bank.

Provision for Income Taxes

The Company’s effective tax rate was 28.5% for the nine months ended September 30, 2021, as compared to 25.8% for the year ended December 31, 2020. The reduced effective tax rate in the prior year was made possible through the provisions of the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) which provided the Company with an opportunity to file amended tax returns and generate proposed refunds of approximately $805,000. While the Company has initiated several tax strategies in anticipation of future tax rate increases, it is not anticipated that any will directly impact the Company's effective tax rate until such rate changes have been legislatively approved. Other differences between the Company's effective tax rate and applicable federal and state statutory rates are due to the proportion of non-taxable revenue and low income housing tax credits as compared to the levels of pre-tax earnings.

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:
