Balance Sheet
Total loans outstanding, excluding PPP, grew to $6.45 billion as of December 31, 2022, an increase of 32.8% over the prior twelve months, of which 17.3% was related to organic loan growth. Investments increased to $2.63 billion as of December 31, 2022, an increase of 8.5% annualized over the prior year quarter end. Quarterly average earning assets to quarterly total average assets were generally unchanged at 91.4% at December 31, 2022, as compared to 92.0% and 93.0% at September 30, 2022, and December 31, 2021, respectively. The loan to deposit ratio was 77.4% at December 31, 2022, as compared to 73.0% and 66.7% at September 30, 2022, and December 31, 2021, respectively.
Total shareholders' equity increased by $56.1 million during the quarter ended December 31, 2022, as a result of an improvement in accumulated other comprehensive losses of $28.8 million and net income of $36.3 million, partially offset by cash dividend payments on common stock of approximately $9,999,000. As a result, the Company's book value was $31.39 per share at December 31, 2022 as compared to $29.71 and $33.64 at September 30, 2022, and December 31, 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 $21.76 per share at December 31, 2022, as compared to $19.92 and $25.80 at September 30, 2022, and December 31, 2021, respectively.

Organic loan growth, excluding PPP, of $136.5 million or 8.6% on an annualized basis was realized during the quarter ended December 31, 2022, primarily within commercial real estate. During the quarter, and exclusive of PPP balance changes, loan originations/draws totaled approximately $479.0 million while payoffs/repayments of loans totaled $343.0 million, which compares to origination/draws and payoff/repayments activity during the three months ended September 30, 2022 of $737.0 million and $536.0 million, respectively. While management believes the loan pipeline remain sufficient to support projected loan growth, loan pipeline activity has moderated due to customer sensitivity from the rising interest rate environment and Company's continued focus on disciplined underwriting. Investment security balances decreased $34.9 million or 5.2% on an annualized basis as the result of prepayments/maturities totaling approximating $62.0 million, partially offset by increases in the market value of securities. Management seeks to utilize excess cash flows from the investment security portfolio to support loan growth or reduce borrowings thus resulting in an improved the mix of earning assets. Deposit balances also decreased, with a change of $326.8 million or 15.1% annualized during the period. Cash flow needs were supported by net short-term FHLB advances totaling $216.7 million as of and for the quarter ended December 31, 2022.

Non-PPP loan balances increased as a result of organic activities by approximately $841.4 million or 17.3% during the twelve month period ending December 31, 2022. Investment securities increased to $2.6 billion at December 31, 2022, an organic change of $95.7 million or 3.9% from the prior year. When combined with balances acquired from Valley Republic Bank, this represents an increase of approximately $1.7 billion in earning assets during the last twelve months and an increase of more than $1.1 billion in average earning assets during the same period.
Net Interest Income and Net Interest Margin
During the year ended December 31, 2022 the Federal Open Market Committee's (FOMC) actions have resulted in seven rate hike events for a cumulative increase in the Fed Funds Rate of 4.25%. During the same period the Company's yield on total loans (excluding PPP) increased 37 basis points to 5.10% for the three months ended December 31, 2022, from 4.73% for the three months ended December 31, 2021. Moreover, the tax equivalent yield on the Company's investment security portfolio increased by 1.44% to 3.13% during the year ended December 31, 2022. The cost of total interest-bearing deposits and total interest-bearing liabilities increased by 12 basis points and 21 basis points respectively between the three month periods ended December 31, 2022 and 2021.
As is common within the banking industry and more specific to the Company's history of deposit cost changes in a rising rate environment, management has observed a lagging or delayed reaction to changes in its deposit costs, particularly during periods of time when the Fed Funds Rate is 3.50% or less. The Company is able to better manage its cost of deposits through the use of exception based pricing strategies and delayed changes to the deposit rates offered to the general public. More specifically, the Company only recently, during December 2022, increased certain of the rates offered to deposit customers. Since FOMC rate actions began, the Company's total cost of deposits have increased 6 basis points which translates to a cycle to date deposit Beta of 1.41%.

(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 2022 as compared to 2021. During the three months ended December 31, 2022, September 30, 2022, and December 31, 2021, purchased loan discount accretion was $1,751,000, $714,000, and $1,780,000, 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 December 31, 2022 increased $4.8 million or 5.1% to $99.3 million compared to $94.5 million during the three months ended September 30, 2022. In addition, net interest margin improved 32 basis points to 4.34%, as compared to the trailing quarter. The increase in net interest income is primarily attributed to an additional $5.8 million in loan interest and fee income and $1.7 million in investment income, due to increases in average volume and rates as compared to the trailing quarter, respectively. As a partial offset, increases in interest rates on deposits and subordinated debt led to an increase of $1.2 million and $250,000, respectively, in interest expense over the same period.

As compared to the same quarter in the prior year, average loan yields, excluding PPP, increased 37 basis points from 4.73% during the three months ended December 31, 2021, to 5.10% during the three months ended December 31, 2022. The accretion of discounts from acquired loans added 11 and 15 basis points to loan yields during the quarters ended December 31, 2022 and December 31, 2021, respectively. Therefore, the 37 basis point increase in yields on loans during the comparable three month periods ended December 31, 2022 and 2021 was the net effect of a 41 basis point increase in market loan rates, partially offset by a 4 basis point decline in the accretion of discounts.
The rates paid on interest bearing deposits increased by 10 basis points during the quarter ended December 31, 2022 compared to the trailing quarter. The cost of interest-bearing deposits increased by 12 basis points between the quarter ended December 31, 2022 and the same quarter of the prior year. In addition, the level of noninterest-bearing deposits increased by approximately $18.0 million quarter over quarter and continues to benefit the average cost of total deposits, which increased by 6 basis points as compared to the trailing quarter, and fourth quarter of prior year. As of December 31, 2022, the ratio of average total noninterest-bearing deposits to total average deposits was 42.9%.

Interest Rates and Earning Asset Composition
During the quarter ended December 31, 2022, market interest rates, including many rates that serve as reference indices for variable rate loans and investment securities continued to increase. As noted above, these rate increases have continued to benefit growth in total interest income. As of December 31, 2022, the Company's loan portfolio consisted of approximately $6.4 billion in outstanding principal with a weighted average coupon rate of 4.89%. During the three month periods ending December 31, 2022, September 30, 2022 and June 20, 2022, the weighted average coupon on loan production in the quarter was 6.25%, 5.24% and 4.45%, respectively. Included in the December 31, 2022 loan total are variable rate loans totaling $3.6 billion, of which, $875 million are considered floating based on the Wall Street Prime index. In addition, the Company holds certain investment securities totaling $408 million which are subject to repricing on not less than a quarterly basis.

Asset Quality and Credit Loss Provisioning
During the three months ended December 31, 2022, the Company recorded a provision for credit losses of $4,245,000, as compared to $3,795,000 during the trailing quarter, and $980,000 during the fourth quarter of 2021.
The following table presents details of the provision for credit losses for the periods indicated:

The allowance for credit losses (ACL) was $105,680,000 as of December 31, 2022, a net increase of $4,192,000 over the immediately preceding quarter. The provision for credit losses of $4,300,000 during the quarter was the net effect of increases in required reserves due to qualitative factors, individually analyzed credits and quantitative reserves under the cohort model. In addition to the aforementioned quarterly increase, the provision for credit losses of $17,945,000 during the year ended December 31, 2022 was largely comprised of $10,820,000 in day 1 required reserves from loans acquired in connection with the Valley Republic Bank merger in the first quarter of 2022. For the quarter, the qualitative components of the ACL resulted in a net increase in required reserves totaling approximately $2,950,000, 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. Meanwhile, the quantitative component of the ACL increased reserve requirements by approximately $1,240,000 over the trailing quarter due to loan volume growth and increases in specific reserves.
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. 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 flattening or 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.
Loans past due 30 days or more decreased by $1,524,000 during the quarter ended December 31, 2022 to $4,947,000, as compared to $6,471,000 at September 30, 2022. Non-performing loans were $21,321,000 at December 31, 2022, an increase of $3,850,000 from $17,471,000 as of September 30, 2022, and a decrease of $9,029,000 from $30,350,000 as of December 31, 2021. Of the $21,321,000 loans designated as non-performing, approximately $19,500,000 are less than 30 days past due as of December 31, 2022. 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.
The following table illustrates the total loans by risk rating and their respective percentage of total loans for the periods presented.

The ratio of classified loans increased to 1.11% as of December 31, 2022 as compared to 0.86% in the trailing quarter, and increased by 5 basis points from the equivalent period in 2021. The Company's criticized loan balances increased during the current quarter by $18,017,000 to $198,502,000 as of December 31, 2022. This change was primarily driven by one newly criticized relationship totaling approximately $22,400,000 that is performing as agreed and believed by management to be well-secured but was downgraded to substandard during the quarter.
There was one property added to Other Real Estate Owned totaling $311,000 during the quarter ended December 31, 2022, and one disposal totaling $394,000. As of December 31, 2022, other real estate owned consisted of nine properties with a carrying value of approximately $3,439,000.

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 1.64% as of December 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 December 31, 2022, the unamortized discount associated with acquired loans totaled $30.5 million and, if aggregated with the ACL, would collectively represent 2.10% of total gross loans and 2.11% 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) December 31, 2022 December 31, 2021
Total number of PPP loans outstanding 10 450
PPP loan balance (TCBK round 1 origination), gross $ 396 $ 2,544
PPP loan balance (TCBK round 2 origination), gross 235 60,767
Acquired PPP loan balance (VRB origination), gross 986 -
Total PPP loans, gross outstanding $ 1,617 $ 63,311
PPP deferred loan fees (Round 1 origination) - 1
PPP deferred loan fees (Round 2 origination) 15 2,163
Total PPP deferred loan fees (costs) outstanding $ 15 $ 2,164
As of December 31, 2022, there was approximately $15,000 in net deferred fee income remaining to be recognized. During the three months ended December 31, 2022, the Company recognized $12,000 in fees on PPP loans as compared with $291,000 and
9

$3,842,000 for the three months ended September 30, 2022 and December 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 increased $240,000 or 1.5% to $15,880,000 during the three months ended December 31, 2022, compared to $15,640,000 during the quarter ended September 30, 2022. Other income increased by $558,000 largely from an increase in fees earned from the sale of deposits, but partially offset by a decline in service charges on deposits accounts totaling $333,000, which is directly related to the Company's decision to no longer charge fees for returned check items.
The following table presents the key components of non-interest income for the current and prior year periods indicated:

Generally, the increases in recurring non-interest income service charges and fees reflects the VRB merger closing in March of 2022, and therefore, related income for the combined entities are only being captured within the most recent three months ended December 31, 2022. As noted above, decreasing mortgage related activity resulting from elevated interest rates reduced the gain on

sale of loans recorded during the quarter by $1,475,000 or 88.2%, as compared to the three months ended December 31, 2021. Further, other non-interest income declined by $599,000 or 37.1% during the quarter ended December 31, 2022 as the last quarter of 2021 included non-recurring death benefit proceeds of $702,000.

Non-interest expense for the quarter ended December 31, 2022 increased $5.0 million or 9.2% to $59.5 million as compared to $54.5 million during the trailing quarter ended September 30, 2022. Total salaries and benefits expense increased by $3.1 million or 9.2%, led primarily by an expense of approximately $2.1 million in benefits and other compensation costs, related to the previously announced amendments to certain of the Company's retirement plans. Additionally, incentive compensation related expenses increased by $1.4 million or 28.5% compared to the trailing quarter, due to strong overall Company performance. Advertising costs increased $259,000 or 26.2% during the quarter, connected to an increase in media advertising for promotional campaigns. ATM and point of service network charges increased $440,000 or 26.0% to $2,134,000, linked with card processing equipment conversion expenses of $256,000 in the current quarter. Finally, other miscellaneous expenses increased $683,000 or 17.0% to $4,691,000, resulting largely from $517,000 in additional appraisal costs during the most recent quarter.

Average full-time equivalent staff 1,210 1,074 136 12.7 %
Generally, the increases in recurring non-interest expense items reflect the VRB merger closing in March of 2022, and therefore, related expenses for the combined entities, less certain realized cost savings, are only being captured within the most recent three months ended December 31, 2022. Total non-interest expense increased $12.8 million or 27.4% to $59.5 million during the three months ended December 31, 2022 as compared to $46.7 million for the quarter ended December 31, 2021. Total salaries and benefits expense increased by $8.9 million or 32.3% to $36.6 million, largely from a net increase of 99 full-time equivalent positions following the aforementioned merger with VRB, the build out of other loan production and compliance teams, and the continued strength of organic growth within the loan portfolio driving incentive compensation expense. As noted above, amendments to certain of the Company's retirement plans, contributed to approximately $2.1 million of the $3.7 million increase associated with benefits and other compensation costs. Management believes that these amendments will result in better alignment of compensation costs and the Company's strategic goals as management anticipates that the future service costs associated with these amended retirement plans will be substantially reduced.

Provision for Income Taxes
The Company's effective tax rate was 27.9% for the year ended December 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.

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:
