TRICO BANCSHARES ANNOUNCES SECOND QUARTER 2023 RESULTS

Notable Items for Second Quarter 2023

•Net income was $24.9 million compared to $35.8 million in the trailing quarter, and compared to $31.4 million in the same quarter of the prior year; Pre-tax pre-provision net revenue was $43.1 million compared to $53.2 million in the trailing quarter, and compared to $45.2 million in the same quarter of the prior year

•Loan balances increased by $98.3 million or 6.1% (annualized) versus the prior quarter and deposit balances increased by $69.5 million or 3.5% (annualized) versus the prior quarter and the Bank has not utilized brokered deposits or FRB borrowing facilities

•The average cost of total deposits was 0.58% for the quarter as compared to 0.25% in the trailing quarter and 0.04% in the same quarter of the prior year and, as a result, the Company's total cost of deposits have increased 54 basis points since FOMC rate actions began, which translates to a cycle-to-date deposit beta of 10.8%

•Balance sheet flexibility remains anchored in readily accessible sources of liquidity including undrawn borrowing capacities, on-balance sheet cash and unpledged investment securities totaling nearly $4.4 billion

•Overall credit quality remains within historical norms as non-performing assets represent approximately 0.41% of total assets and the ratio of classified loans to total loans remains below one percent

•Average yield on earning assets was 4.78%, an increase of 14 basis points over the 4.64% in the trailing quarter; net interest margin was 3.96%, a change of 25 basis points from 4.21% in the trailing quarter

•Operations, as evidenced by the increase in the efficiency ratio from 50.3% in the trailing quarter to 58.7% in the current quarter, were impacted by a variety of both recurring and non-recurring activities

"We were pleased by our ability to grow deposits during the quarter while doing so without the use of brokered funding sources and at rates that were favorable to the Bank. Although nonaccrual and classified loans have increased, they remain below historical averages. Through the Bank's ongoing portfolio review processes and active management, we have not identified any evidence of systemic risk," explained Rick Smith, President and Chief Executive Officer. Peter Wiese, EVP and Chief Financial Officer added, "As deposit balances grew and repayment of principal from the investment security portfolio accelerated, excess proceeds were utilized to reduce the balance and costs associated with short-term borrowing. As we look to the second half of 2023, margin preservation and expense control will be our focused priorities."

Balance Sheet

Total loans outstanding, excluding PPP, grew to $6.5 billion as of June 30, 2023, an increase of 7.0% over the prior twelve months, and is entirely related to organic loan growth. As compared to March 31, 2023, total loans outstanding increased by $98.3 million or 6.1% annualized. Investments decreased to $2.49 billion as of June 30, 2023, an annualized decrease of 14.3% over the prior year quarter end. Quarterly average earning assets to quarterly total average assets were 91.6% on June 30, 2023, as compared to 91.4% and 92.2% at December 31, 2022, and June 30, 2022, respectively. The loan-to-deposit ratio was 80.5% on June 30, 2023, as compared to 80.0% and 69.8% at December 31, 2022, and June 30, 2022, respectively. During the current year to date period, and throughout the 2022 fiscal year, the Company held no brokered deposits and relied solely on short-term borrowings to fund cash flow timing differences.

Total shareholders' equity increased by $2.5 million during the quarter ended June 30, 2023, as a result of accumulated other comprehensive losses increasing by $11.9 million and cash dividend payments on common stock of approximately $10.0 million, offset by net income of $24.9 million. As a result, the Company’s book value was $32.86 per share at June 30, 2023, as compared to $32.84 and $31.25 at December 31, 2022 and June 30, 2022, 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 $23.30 per share at June 30, 2023, as compared to $23.22 and $21.41 at December 31, 2022, and June 30, 2022, respectively.

Trailing Quarter Balance Sheet Change

Ending balances	June 30,		March 31,				Annualized  % Change
(dollars in thousands)	2023		2023		$ Change
Total assets	$	9,853,421	$	9,842,394	$	11,027	0.4	%

Total deposits	8,095,365		8,025,865		69,500		3.5
Total other borrowings	$	392,714	$	434,140	$	(41,426)	(38.2)	%

Loans outstanding increased by $98.3 million or 6.1% on an annualized basis during the quarter ended June 30, 2023. During the quarter, loan originations/draws totaled approximately $456.0 million while payoffs/repayments of loans totaled $356.0 million, which compares to originations/draws and payoffs/repayments during the trailing quarter ended of $357.0 million and $389.0 million, respectively. While origination volume increased from the previous quarter, activity levels continue to be lower relative to the comparative period in 2022 due in part to disciplined pricing and underwriting, as well as decreased borrower appetite at currently offered lending rates. Management continues to believe that the current loan pipeline is sufficient to support the Company's objectives. Investment security balances decreased $92.4 million or 14.3% on an annualized basis as the result of net prepayments, maturities, and purchases totaling approximating $75.2 million and net decreases in the market value of securities of $16.9 million. Management seeks to utilize excess cash flows from the investment security portfolio to support loan growth or reduce borrowings thus resulting in an improved mix of earning assets. Deposit balances increased by $69.5 million or 3.5% annualized during the period. Net cash flow surpluses during the quarter resulted in a net decrease of $41.4 million in short-term borrowings, which totaled $392.7 million as of the period ended June 30, 2023.

At June 30, 2023, the Company's primary sources of liquidity represented 54.2% of total deposits and 174% of estimated total uninsured (excluding collateralized municipal deposits and intercompany balances) deposits, respectively. As secondary sources of liquidity, the Company's held-to-maturity investment securities had a fair value of $134.4 million, including approximately $10.7 million in net unrealized losses. The Company did not utilize any brokered deposits during 2023 or 2022.

Net Interest Income and Net Interest Margin

During the twelve-month period ended June 30, 2023, the Federal Open Market Committee's (FOMC) actions have resulted in an increase in the Fed Funds Rate by 350 basis points. During the same period the Company's yield on total loans (excluding PPP) increased 68 basis points to 5.38% for the three months ended June 30, 2023, from 4.70% for the three months ended June 30, 2022. Moreover, the tax equivalent yield on the Company's investment security portfolio increased by 88 basis points to 3.24% during the twelve months ended June 30, 2023. The cost of total interest-bearing deposits and total interest-bearing liabilities increased by 88 basis points and 122 basis points, respectively, between the three-month periods ended June 30, 2023 and 2022. Since FOMC rate actions began, the Company's cost of total deposits has increased 54 basis points which translates to a cycle to date deposit beta of 10.80%.

The Company continues to manage its cost of deposits through the use of pricing strategies and delayed changes to the deposit rates offered to the general public. As of June 30, 2023, March 31, 2023, and December 31, 2022, total deposits priced utilizing these strategies totaled $1,070.7 million, $731.9 million and $579.1 million, respectively, and carried weighted average rates of 3.38%, 2.68% and 1.64%, respectively.

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. 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 2023 as compared to 2022. During the three months ended June 30, 2023, March 31, 2023, and June 30, 2022, purchased loan discount accretion was $1.5 million, $1.4 million, and $1.7 million, 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, 2023, decreased $4.7 million or 5.1% to $89.0 million compared to $93.7 million during the three months ended March 31, 2023. In addition, net interest margin declined 25 basis points to 3.96%, compared to the trailing quarter. The decrease in net interest income is primarily attributed to an additional $6.3 million in deposit interest expense and $2.6 million in additional interest expense on other borrowings, both due to increases in interest rates as compared to the trailing quarter. As a partial offset, total interest income also increased as compared to the trailing quarter, up $4.3 million or 4.1%.

As compared to the same quarter in the prior year, average loan yields, excluding PPP, increased 68 basis points from 4.70% during the three months ended June 30, 2022, to 5.38% during the three months ended June 30, 2023. The accretion of discounts from acquired loans added 9 and 11 basis points to loan yields during the quarters ended June 30, 2023 and June 30, 2022, respectively.

The rates paid on interest bearing deposits increased by 52 basis points during the quarter ended June 30, 2023, compared to the trailing quarter. The cost of interest-bearing deposits increased by 88 basis points between the quarter ended June 30, 2023, and the same quarter of the prior year. In addition, the average balance of noninterest-bearing deposits decreased by $244.1 million quarter over quarter. As of June 30, 2023, the ratio of average total noninterest-bearing deposits to total average deposits was 39.2%, as compared to 41.0% and 41.2% at March 31, 2023 and June 30, 2022, respectively.

Interest Rates and Earning Asset Composition

During the quarter ended June 30, 2023, 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 June 30, 2023, the Company's loan portfolio consisted of approximately $6.5 billion in outstanding principal with a weighted average coupon rate of 5.15%. During the three-month periods ending June 30, 2023, March 31, 2023, and December 31, 2022, the weighted average coupon on loan production in the quarter was 6.85%, 6.71%, and 6.05%, respectively. Included in the June 30, 2023 loan total are adjustable rate loans totaling $3.8 billion, of which, $859.9 million are considered floating based on the Wall Street Prime index. In addition, the Company holds certain investment securities with fair values totaling $375.5 million which are subject to repricing on not less than a quarterly basis.

Asset Quality and Credit Loss Provisioning

During the three months ended June 30, 2023, the Company recorded a provision for credit losses of $9.7 million, as compared to $4.2 million during the trailing quarter, and $2.1 million during the first quarter of 2022.

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

	Three months ended				Six months ended
(dollars in thousands)	June 30, 2023		June 30, 2022		June 30, 2023		June 30, 2022

Balance, end of period	$	117,329	$	97,944	$	117,329	$	97,944

The allowance for credit losses (ACL) was $117.3 million as of June 30, 2023, a net increase of $8.9 million over the immediately preceding quarter. The provision for credit losses of $9.0 million during the recent quarter was the net effect of increases in required reserves due to individually analyzed credits, qualitative factors, and quantitative reserves under the cohort model. On a comparative basis, the provision for credit losses of $1.9 million during the three months ended June 30, 2022, was largely the result of loan growth in the period. For the current quarter, the qualitative components of the ACL resulted in a net increase in required reserves totaling approximately $2.9 million due to softening of the California employment data, and increase in the corporate debt yields. Meanwhile, the quantitative component of the ACL increased reserve requirements by approximately $6.0 million over the trailing quarter primarily due to 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 includes 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. Despite continued declines on a year over year comparative basis, core inflation remains elevated from wage pressures, and higher living costs such as housing and food prices. Management notes the rapid intervals of rate increases by the Federal Reserve and flattening or inversion of the yield curve, have informed expectations of the US entering a recession within 12 months. As a result, management continues to believe that certain credit weaknesses 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 increased by $1.6 million during the quarter ended June 30, 2023, to $9.5 million, as compared to $7.9 million at March 31, 2023. Non-performing loans were $37.6 million at June 30, 2023, an increase of $21.6 million from $16.0 million as of March 31, 2023, and an increase of $25.7 million from $11.9 million as of June 30, 2022. The current quarter increase in non-performing assets is nearly entirely attributed to a single relationship. Of the $37.6 million loans designated as non-performing as of June 30, 2023, approximately $31.7 million are current with respect to payments required under their original loan agreements.

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

	June 30,			% of Loans Outstanding		March 31,			% of Loans Outstanding		June 30,			% of Loans Outstanding
(dollars in thousands)	2023					2023					2022
Risk Rating:

Loans past due 30+ days to total loans	0.15		%			0.12		%			0.10		%

The ratio of classified loans of 1.00% as of June 30, 2023, remained consistent with the trailing quarter, but increased by 23 basis points from June 30, 2022. The Company's criticized loan balances increased during the current quarter by $31.4 million to $220.8 million as of June 30, 2023. The recent increase in special mention loans as a percentage of total loans outstanding is consistent with volumes experienced prior to the recent quantitative easing cycle spurred by the COVID pandemic and reflects management's historically conservative approach to credit risk monitoring. The newly criticized special mention loans are spread amongst a handful of relationships, with diversity amongst geographies and collateral types.

There were no properties added or disposed within Other Real Estate Owned during the second quarter of 2023. Total write-downs of $0.5 million were incurred during the current quarter across four properties. As of June 30, 2023, other real estate owned consisted of nine properties with a carrying value of approximately $2.9 million.

Non-performing assets of $40.5 million at June 30, 2023, represented 0.41% of total assets, a change from the $19.5 million or 0.20% and $15.3 million or 0.15% as of March 31, 2023 and June 30, 2022, respectively.

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, 2023, the unamortized discount associated with acquired loans totaled $27.6 million.

The declining mortgage related activity resulting from elevated interest rates reduced income recorded from the sale of loans by $0.2 million or 45.6%, and to a lesser extent a smaller change in the fair value of mortgage servicing rights, as compared to the three months ended June 30, 2022. Other non-interest income reductions of $0.4 million were primarily the result of a $0.3 million difference in fair value changes of assets associated with retirement plans where the corresponding offset of those changes are included in benefits and other compensation costs.

Non-interest expense for the quarter ended June 30, 2023, increased $7.4 million or 13.8% to $61.2 million as compared to $53.8 million during the trailing quarter ended March 31, 2023. Total salaries and benefits expense increased by $2.2 million or 6.6%, led by $1.5 million of growth in incentive compensation expense related to the achievement of certain loan and deposit volume targets and a $1.1 million or 4.6% increase in salaries which were primarily driven by Company-wide merit increases which became effective in late March of this year. Data processing and software expenses increased by $0.6 million or 15.0% related to ongoing investments in the Company's data management and security infrastructure. Advertising costs increased $0.3 million or 33.9% during the quarter, connected to an increase in media advertising for promotional campaigns. Professional fees for the three months ended June 30, 2023, include approximately $0.7 million in costs associated with third party assistance with contract negotiation, the benefits of which will be realized in future periods. Regulatory assessments increased $1.2 million or 151.6% during the quarter as a result of increases in assessment rates. Management estimates that the near-term future quarterly run rate of these regulatory assessment expenses will be approximately $1.7 million per quarter, but anticipates that these costs will increase further if the economic environment in which the Company operates continues to deteriorate. The Company does not anticipate that it will be subject to the recently announced special assessments as its total uninsured deposits do not exceed $5.0 billion. Operational losses also increased by $0.7 million or 150.6%, primarily as a result of burglary at several ATM machines. Other miscellaneous expenses increased $1.7 million or 49.3%, due primarily to changes in regulatory requirements which is expected to result in an estimated $0.8 million in refunds to customers previously charged non-sufficient funds fees and an additional increase of $0.5 million in provision expense on real estate owned and various other increases across the Company, including travel and entertainment costs.

Total salaries and benefits expense increased by $1.8 million or 5.4% to $34.7 million, largely from a net increase of 27 full-time equivalent positions as well as annual merit increases as previously discussed. Professional fees increased by $0.7 million which was directly associated with third party contract negotiation assistance, the benefits of which will be realized in future periods. Other miscellaneous expenses increased $1.2 million or 29.5%, due primarily to changes in regulatory requirements which is expected to result in an estimated $0.8 million in refunds to customers previously charged non-sufficient funds fees and an additional increase of $0.5 million in provision expense on real estate owned and various other increases across the Company, including travel and entertainment costs. Merger and acquisition expenses associated with the VRB merger totaled $2.2 million for the quarter ended June of 2022. The reasons for changes in data processing and software, and operational losses, are consistent with the discussions previously provided.

Total non-interest expense increased $12.3 million or 12.0% to $115.0 million during the six months ended June 30, 2023, as compared to $102.7 million for the comparative period in 2022, for reasons primarily associated with the acquisition of Valley Republic Bank in March of 2022 which resulted in expense increases for nearly every identified category. Merger and acquisition expenses associated with the VRB merger totaled $6.2 million for the six-month period ended 2022. The reasons for additional and more specific changes in various costs identified above, and including but not limited to data processing, regulatory assessments, operational losses and other expenses are consistent with the discussions previously provided.

Provision for Income Taxes

The Company’s effective tax rate was 25.6% for the quarter ended June 30, 2023, as compared to 26.8% for the period ended March 31, 2023, and 28.1% for the year ended December 31, 2022. 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:

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 impacts on the Company's business condition and financial operating results; the impact of changes in financial services industry policies, laws and regulations; regulatory restrictions on our ability to successfully market and price our products to consumers; technological changes; weather, natural disasters 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 impact of a slowing U.S. economy and potentially increased unemployment on the performance of our loan portfolio, the market value of our investment securities, the availability of, and cost of, sources of funding and the demand for our products; adverse developments with respect to U.S. or global economic conditions and other uncertainties, including the impact of supply chain disruptions, commodities prices, inflationary pressures and labor shortages on the economic recovery and our business; the impacts of international hostilities, terrorism or geopolitical events; adverse developments in the financial services industry generally such as the recent bank failures and any related impact on depositor behavior or investor sentiment; risks related to the sufficiency of liquidity; the possibility that our recorded goodwill could become impaired, which may have an adverse impact on our earnings and capital; the costs or effects of mergers, acquisitions or dispositions we may make, as well as whether we are able to obtain any required governmental approvals in connection with any such activities, or identify and complete favorable transactions in the future, and/or realize the contemplated financial business benefits; the regulatory and financial impacts associated with exceeding $10 billion in total assets; the negative impact on our reputation and profitability in the event customers experience economic harm or in the event that regulatory violations are identified; the ability to execute our business plan in new lending markets; the future operating or financial performance of the Company, including our outlook for future growth and changes in the level and direction of our nonperforming assets and charge-offs; the appropriateness of the allowance for credit losses, including the 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 effectiveness of the Company's asset management activities in improving, resolving or liquidating lower-quality assets; the effect of changes in the financial performance and/or condition of our borrowers; changes in accounting standards and practices; possible other-than-temporary impairment of securities held by us due to changes in credit quality or rates; changes in consumer spending, borrowing and savings habits; our ability to attract and maintain deposits and other sources of liquidity; the effects of changes in the level or cost of checking or savings account deposits on our funding costs and net interest margin; increasing noninterest expense and its impact on our efficiency ratio; competition and innovation with respect to financial products and services by banks, financial institutions and non-traditional providers including retail businesses and technology companies; the challenges of attracting, integrating and retaining key employees; the vulnerability of the Company's operational or security systems or infrastructure including the impact of the recent cyber security ransomware incident on our operations and reputation, the systems of third-party vendors or other service providers with whom the Company contracts, and the Company's customers to unauthorized access, computer viruses, phishing schemes, spam attacks, human error, natural disasters, power loss and data/security breaches and the cost to defend against and respond to such incidents; increased data security risks due to work from home arrangements and email vulnerability; failure to safeguard personal information; the effect of a fall in stock market prices on our brokerage and wealth management businesses; the transition away from the London Interbank Offered Rate toward new interest rate benchmarks; the costs and effects of litigation and of unexpected or adverse outcomes in such litigation; 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, 2022, which has been filed with the Securities and Exchange Commission (the “SEC”) and all subsequent filings with the SEC under Sections 13(a), 13(c), 14, and 15(d) of the Securities Act of 1934, as amended. Such filings are also available in the “Investor Relations” section of our website, https://www.tcbk.com/investor-relations and in other documents we file with the SEC. Annualized, pro forma, projections and estimates are not forecasts and may not reflect actual results.
