Balance Sheet

Total loans outstanding, excluding PPP, grew to $6.10 billion as of June 30, 2022, an increase of 29.5% over the prior twelve months, of which 13.6% was related to organic loan growth. Investments increased to $2.80 billion as of June 30, 2022, an increase of 33.2% annualized over the prior twelve months. Quarterly average earning assets to quarterly total average assets were generally unchanged at 92.2% at June 30, 2022, as compared to 92.9% and 92.8% at March 31, 2022, and June 30, 2021, respectively. The loan to deposit ratio was 69.8% at June 30, 2022, as compared to 67.2% and 70.7% at March 31, 2022, and June 30, 2021, respectively.

Total shareholders' equity decreased by $67,005,000 during the quarter ended June 30, 2022, as a result of an increase in accumulated other comprehensive losses of $68,611,000, share repurchases totaling approximately $21,750,000, and cash dividend payments on common stock of $8,360,000, partially offset by net income of $31,364,000. As a result, the Company’s book value was $31.25 per share at June 30, 2022 as compared to $32.78 and $32.53 at March 31, 2022, and June 30, 2021, 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 $21.41 per share at June 30, 2022, as compared to $23.04 and $24.60 at March 31, 2022, and June 30, 2021, respectively.

Total deposits			$	8,756,775					$	8,714,477					$	42,298																	1.9		%

Organic loan growth, excluding PPP, of $300,297,000 or 20.7% on an annualized basis was realized during the quarter ended June 30, 2022, primarily within commercial real estate. During the quarter, and exclusive of PPP balance changes, loan originations totaled approximately $697 million while payoffs of loans totaled $397 million, which compares to origination and payoff activity during the three months ended March 31, 2022 of $396 million and $225 million, respectively. While management believes that loan pipelines are robust, loan activity during the quarter is reflective of increased customer awareness of the rising interest rate environment. Investment security growth was $233,109,000 or 36.3% on an annualized basis as excess liquidity from strong deposit growth during the trailing 12 month period was put to use in higher yielding earning assets. Deposit balances increased, with an organic change of $42,298,000 or 1.9% annualized during the period.

Non-PPP loan balances have increased as a result of organic activities by approximately $638,387,000 during the twelve month period ending June 30, 2022. This, combined with earning assets acquired in the merger with Valley Republic Bank, has led to a long-term beneficial and meaningful shift in the makeup of the loan portfolio. Specifically, during the twelve months ended June 30, 2022 and excluding PPP balance changes, loan originations totaled approximately $2.2 billion while payoffs of loans totaled $1.6 billion. Investment securities increased to $2,802,815,000 at June 30, 2022, an organic change of $589,524,000 or 28.0% from the prior year.

(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 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 two quarters of 2022. During the three months ended June 30, 2022, March 31, 2022, and June 30, 2021, purchased loan discount accretion was $1,677,000, $1,323,000, and $2,566,000, respectively.

(1)Fully taxable equivalent (FTE). All yields and rates are calculated using specific day counts for the period and year as applicable.

(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 June 30, 2022 increased $17,236,000 or 25.3% to $85,443,000 compared to $68,207,000 during the three months ended March 31, 2022. In addition, net interest margin improved 28 basis points to 3.67%, as compared to the trailing quarter. The increase in net interest income is primarily attributed to an additional $4,622,000 in investment revenues and $1,079,000 in revenues on cash balances due to increases in average volume and rates, respectively. As a partial offset, increases in the average balance and rates on subordinated debt resulted in an increase in interest expense of $469,000 over the trailing quarter.

As compared to the same quarter in the prior year, average loan yields, excluding PPP, decreased 23 basis points from 4.93% during the three months ended June 30, 2021, to 4.70% during the three months ended June 30, 2022. The accretion of discounts from acquired loans added 11 and 22 basis points to loan yields during the quarters ended June 30, 2022 and June 30, 2021, respectively. Therefore, of the 23 basis point decrease in yields on loans during the comparable three month periods ended June 30, 2022 and 2021, 12 basis points was attributable to changes in competitive market rates, while 11 basis points resulted from less accretion of discounts.

The rates paid on interest bearing deposits generally remained flat during the quarter ended June 30, 2022 compared to the trailing quarter. The cost of interest-bearing deposits decreased by 1 basis point during the quarter ended June 30, 2022, to 0.07% from 0.08% 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 0.5% in the second quarter of the prior year. Specifically, the ratio of average total noninterest-bearing deposits to total average deposits was 41.2% and 40.6% as of June 30, 2022 and March 31, 2022, respectively, as compared to 40.5% for the quarter ended June 30, 2021.

Interest Rates and Loan Portfolio Composition

During the quarter ended June 30, 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 temporary downward bias due to the timing associated with the repricing of variable rate loans and continued market competition. As of June 30, 2022, the Company's loan portfolio consisted of approximately $6.1 billion in outstanding principal with a weighted average coupon rate of 4.39%, inclusive of PPP loans. Excluding PPP loans, the Company's loan portfolio has approximately $6.09 billion outstanding loan balances with a weighted average coupon rate of 4.40% as of June 30, 2022. Included in the June 30, 2022 loan total are variable rate loans totaling $3.5 billion, of which, $875 million are considered floating based on the Wall Street Prime index.

Asset Quality and Credit Loss Provisioning

During the three months ended June 30, 2022, the Company recorded a provision for credit losses of $2,100,000, as compared to a $8,330,000 provision during the trailing quarter, and a reversal of provision expense of $260,000 during the first quarter of 2021.

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

Balance, end of period			$	97,944					$	86,062					$	97,944					$	86,062

The allowance for credit losses (ACL) was $97,944,000 as of June 30, 2022, a net increase of $1,895,000 over the immediately preceding quarter. The provision for credit losses of $1,940,000 during the quarter was the net effect of increases in required reserves due to loan growth and net charge-offs totaling $45,000. By comparison, the provision for credit losses of $10,145,000 during the six-months ended June 30, 2022 was generally comprised of $10,820,000 in association with the loans acquired from Valley Republic Bank and a net reversal of credit losses of $675,000. The qualitative components of the ACL resulted in a net decline in required reserves due to continued improvement in US employment rates and tempered by a weaker outlook of US GDP. Meanwhile, the quantitative component of the ACL increased reserve requirements over the trailing quarter due to loan volume growth partially offset by decreases in reserves associated with specifically evaluated loans.

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 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 $2,482,000 during the quarter ended June 30, 2022 to $5,920,000, as compared to $8,402,000 at March 31, 2022. Non-performing loans were $11,925,000 at June 30, 2022, a decrease of $2,163,000 and $20,780,000 from $14,088,000 and $32,705,000 as of March 31, 2022 and June 30, 2021, respectively.

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

			June 30,			% of Total Loans						March 31,			% of Total Loans						June 30,			% of Total Loans
(dollars in thousands)			2022									2022									2021

Loans past due 30+ days to total loans			0.10		%							0.14		%							0.19		%

The ratio of classified loans to total loans improved to 0.77% as of June 30, 2022 as compared to both 0.84% and 1.18% for the trailing quarter and same quarter of the prior year, respectively. The Company's criticized loan balances decreased during the current quarter by approximately $17,309,000 to $152,640,000 as of June 30, 2022. The improvement in criticized loans was the result of active management by the credit department, as there were no loan sales during the period. The five largest criticized credits upgraded or paid off totaled approximately $8,800,000, and there were no charge-offs incurred in connection with the successful management of these credits.

There was one property added to other real estate owned totaling $375,000 during the quarter ended June 30, 2022, and no disposals. As of June 30, 2022, other real estate owned consisted of nine properties with a carrying value of approximately $3,379,000.

Non-performing assets of $15,304,000 at June 30, 2022 represented 0.15% of total assets, a decrease from the $16,995,000 or 0.17% and $34,952,000 or 0.43% as of March 31, 2022 and June 30, 2021, respectively. The improvement in non-performing assets during the current quarter was spread amongst several lending relationships.

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 1.61% as of June 30, 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 June 30, 2022, the unamortized discount associated with acquired loans totaled $33,100,000 and, if aggregated with the ACL, would collectively represent 2.13% of total gross loans and 2.15% 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)			June 30, 2022						December 31, 2021																		June 30, 2021
Total number of PPP loans outstanding			90						450																		2,209
PPP loan balance (TCBK round 1 origination), gross			$	1,183					$	2,544																	$	51,547
PPP loan balance (TCBK round 2 origination), gross			9,442						60,767																		197,035
Acquired PPP loan balance (VRB origination), gross			7,447						—																		—
Total PPP loans, gross outstanding			$	18,072					$	63,311																	$	248,582
PPP deferred loan fees (Round 1 origination)			—						1																		477
PPP deferred loan fees (Round 2 origination)			318						2,163																		8,513
Total PPP deferred loan fees (costs) outstanding			$	318					$	2,164																	$	8,990

As of June 30, 2022, there was approximately $318,000 in net deferred fee income remaining to be recognized. During the three months ended June 30, 2022, the Company recognized $872,000 in fees on PPP loans as compared with $974,000 and $2,334,000 for the three months ended March 31, 2022 and June 30, 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.

Total non-interest income			$	16,430					$	15,096					$	1,334					8.8		%

Non-interest income increased $1,334,000 or 8.8% to $16,430,000 during the three months ended June 30, 2022, compared to $15,096,000 during the quarter ended March 31, 2022. Generally, the quarter over quarter changes reflect the VRB merger timing of March 25, 2022, and therefore, had minimal benefit in the trailing quarter but are captured fully within the current quarter ended June 30, 2022. As an outlier, the gain on sale of mortgage loans declined by $704,000 or 56.5% during the quarter ended June 30, 2022, attributed to the rapidly rising rate environment and resulting decline in mortgage application and origination volumes.

The following table presents the key components of non-interest income for the current and prior year periods indicated:

Total non-interest income			$	16,430					$	15,957					$	473					3.0		%

In addition to the discussion above, within the non-interest income for the three months ended June 30, 2022, ATM and interchange fees improved $426,000 or 6.5%, as did service charges on deposit accounts totaling $701,000 or 20.2%, both as a result of increased usage due to relaxed social distancing guidelines and growth in deposit customers during the six months ended June 30, 2022, when compared to the same period in the prior year. Further, changes in the value of mortgage service rights, while lesser in magnitude, typically have an inverse relationship with changes in mortgage banking activities.

Non-interest expense for the quarter ended June 30, 2022 increased $9,817,000 or 21.1% to $56,264,000 as compared to $46,447,000 during the trailing quarter ended March 31, 2022. Total salaries and benefits expense increased by $6,171,000 or 23.1%, led by wage related increases of $3,953,000 or 21.7% to $22,169,000 due to a net increase of 99 full-time equivalent positions following the aforementioned merger with VRB, an increase in vacation accruals which management believes are partially seasonal, and annual merit increases which averaged 3.1% and were effective March 28, 2022. Incentive compensation increased by $1,699,000 or 65.8% to $4,282,000 compared to the trailing quarter due to strong overall Company performance and elevated levels of loan production and growth. Merger and acquisition expenses associated with the VRB merger totaled $2,221,000 during the current quarter and are not expected to be significant in future periods. Included in the current quarter's merger and acquisition expenses are costs associated with the contractual obligations owed to a former VRB executive whom recently resigned from the Company to accept employment outside of the banking industry.

During the three months ended March 31, 2022, the Company sold a former administrative building and relocated a branch during the previous quarter resulting in a net gain on disposal of approximately $1,078,000 as noted above.

Provision for Income Taxes

The Company’s effective tax rate was 27.5% for the six months ended June 30, 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.

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:
