Executive Commentary: “Our first quarter results demonstrate our continued efforts to remain focused on the core business activities of adding customers, growing deposits and originating loans. While normally a seasonally slow lending and deposit quarter, both activities were solid despite a volatile economic environment. In addition, we are proud to announce that we have completed our most recent Community Reinvestment Act (CRA) examination resulting in a rating of Outstanding,” said Rick Smith, President and CEO. Peter Wiese, EVP and CFO added, “Both net interest margin and net interest income slightly contracted during the quarter as the tail end of Federal Funds rate cuts impacted floating rate earning assets. While interest rates across the yield curve fluctuated significantly during the quarter, we expect continued incremental increases in earning asset yields as well as incremental reductions in funding costs.”

Selected Financial Highlights |

•For the quarter ended March 31, 2025, the Company’s return on average assets was 1.09%, while the return on average equity was 8.54%; for the trailing quarter ended December 31, 2024, the Company’s return on average assets was 1.19%, while the return on average equity was 9.30%
•Diluted earnings per share were $0.80 for the first quarter of 2025, compared to $0.88 for the trailing quarter and $0.83 during the first quarter of 2024
•The loan to deposit ratio was 83.13% as of March 31, 2025, as compared to 83.69% for the trailing quarter end
•The efficiency ratio was 60.42% for the quarter ended March 31, 2025, as compared to 59.56% for the trailing quarter as net interest income was impacted by the quarter over quarter reduction in calendar days
•The provision for credit losses was approximately $3.7 million during the quarter ended March 31, 2025, as compared to $1.7 million during the trailing quarter end. The change was attributed to an increase in required reserves totaling $4.9 million on individually evaluated loans and an increase of $1.1 million in reserves for unfunded commitments, which were offset by net recoveries and decreases in qualitative factors attributed to general improvement in economic indicators
•The allowance for credit losses (ACL) to total loans was 1.88% as of March 31, 2025, compared to 1.85% as of the trailing quarter end, and 1.83% as of March 31, 2024.

Balance Sheet Data |  |

Total loans outstanding were $6.8 billion as of March 31, 2025, an increase of $20.1 million or 0.3% over March 31, 2024, and an increase of $52.3 million or 3.1% annualized as compared to the trailing quarter ended December 31, 2024. Investments decreased by $57.5 million and $242.4 million for the three and twelve month periods ended March 31, 2025, respectively, and ended the quarter with a balance of $1.98 billion or 20.2% of total assets. Quarterly average earning assets to quarterly total average assets was 91.8% on March 31, 2025, compared to 92.0% at March 31, 2024. The loan-to-deposit ratio was 83.1% on March 31, 2025, as compared to 85.1% at March 31, 2024. The Company did not utilize brokered deposits during 2025 or 2024 and continues to rely on organic deposit customers and short-term borrowings to fund cash flow timing differences.
Total shareholders' equity increased by $34.6 million during the quarter ended March 31, 2025, as net income of $26.4 million and a $22.1 million decrease in accumulated other comprehensive losses were partially offset by $10.9 million in cash dividends on common stock and $4.1 million in share repurchase activity. As a result, the Company’s book value increased to $38.17 per share at March 31, 2025, compared to $37.03 at December 31, 2024. 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 $28.73 per share at March 31, 2025, as compared to $27.60 at December 31, 2024. Changes in the fair value of available-for-sale investment securities, net of deferred taxes, continue to create moderate levels of volatility in tangible book value per share.

Loans outstanding increased by $52.3 million or 3.1% on an annualized basis during the quarter ended March 31, 2025. During the quarter, loan originations/draws totaled approximately $357.5 million while payoffs/repayments of loans totaled $321.3 million, which compares to originations/draws and payoffs/repayments during the trailing quarter ended of $487.9 million and $408.5 million, respectively. Origination volume was slightly elevated relative to the comparative period in 2024, despite elevated interest rates and volatility in the economic outlook of potential borrowers. The activity within loan payoffs/repayments remains spread amongst numerous borrowers, regions and loan types.
Investment security balances decreased $57.5 million or 11.3% on an annualized basis during the quarter as a result of net prepayments/maturities of $71.7 million and sales of $30.0 million, and offset by net increases in the market value of securities of $31.4 million and purchases of $14.4 million. Investment security purchases were comprised of fixed rate agency mortgage-backed securities. While management intends to primarily utilize cash flows from the investment security portfolio and organic deposit growth to support loan growth, excess liquidity will be utilized for purchases of investment securities to support net interest income growth and net interest margin expansion.
Deposit balances increased by $117.8 million or 5.8% annualized during the period, primarily due to increases in savings deposit accounts.

Net Interest Income and Net Interest Margin |  |

The Company's yield on loans for the first quarter was 5.71%, a decrease of 1 and 7 basis points, respectively, as compared to 5.72% for the period ended March 31, 2024, and 5.78% from the trailing quarter. The tax equivalent yield on the Company's investment security portfolio was 3.39% for the quarter ended March 31, 2025, an increase of 1 basis point from the 3.38% for both the three months ended March 31, 2024 and from the trailing quarter. The cost of total interest-bearing deposits increased by 23 basis points, while the costs of total interest-bearing liabilities decreased by 6 basis points, respectively, between the three-month periods ended March 31, 2025 and 2024. As compared to the trailing quarter, both interest-bearing deposits and interest-bearing liabilities declined by 9 basis points. There were no changes to short-term rates by the FOMC during the current quarter, following 100 basis points in cuts during the fourth quarter in 2024. The fully tax-equivalent net interest income and net interest margin was $82.8 million and 3.73%, respectively, for the quarter ended March 31, 2025, and was $84.4 million and 3.76%, respectively for the quarter ended December 31, 2024. More specifically, net interest rate spread improved by 2 basis points to 2.97% for the quarter ended March 31, 2025 as compared to the trailing quarter, while the net interest margin declined by 3 basis points due in large part to the impact of the day count between quarters.
The Company continues to manage its cost of deposits through the use of various pricing and product mix strategies. As of March 31, 2025, December 31, 2024, and March 31, 2024, deposits priced utilizing these customized strategies totaled $0.93 billion, $1.05 billion, and $1.4 billion and carried weighted average rates of 3.43%, 3.59% and 3.75%, 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 March 31, 2025, decreased $1.6 million or 1.8% to $82.8 million compared to $84.4 million during the three months ended December 31, 2024. Net interest margin totaled 3.73% for the three months ended March 31, 2025, a decrease of 3 basis points from the trailing quarter. The decrease in net interest income is primarily attributed to a $2.8 million decline in interest income on earning assets, led by a reduction in loan income of $2.3 million, primarily related to the impact of rate cuts in the trailing quarter on variable rate loans. The decline in interest income was partially offset by reductions in interest expense on interest-bearing liabilities of $1.2 million as compared to the trailing quarter, primarily attributed to a decrease of $1.0 million in deposit interest expense also attributable to a reduction in rates.
As compared to the same quarter in the prior year, average loan yields decreased 1 basis points from 5.72% during the three months ended March 31, 2024, to 5.71% during the three months ended March 31, 2025. The accretion of discounts from acquired loans added 12 basis points and 8 basis points to loan yields during the quarters ended March 31, 2025 and March 31, 2024, respectively. The cost of interest-bearing deposits increased by 23 basis points between the quarter ended March 31, 2025, and the same quarter of the prior year. In addition, the average balance of noninterest-bearing deposits decreased by $132.0 million from the three-month average for the period ended March 31, 2024 amidst a continued migration of customer funds to interest-bearing products.
For the quarter ended March 31, 2025, the ratio of average total noninterest-bearing deposits to total average deposits was 30.7%, as compared to 31.8% and 33.8% for the quarters ended December 31, 2024 and March 31, 2024, respectively.

Interest Rates and Earning Asset Composition

As of March 31, 2025, the Company's loan portfolio consisted of approximately $6.8 billion in outstanding principal with a weighted average coupon rate of 5.50%. During the three-month periods ending March 31, 2025, December 31, 2024, and March 31, 2024, the weighted average coupon on loan production in the quarter was 6.96%, 6.94% and 7.78%, respectively. Included in the March 31, 2025 total loans balance are adjustable rate loans totaling $4.3 billion, of which, $0.9 billion are considered floating based on the Wall Street Prime index. In addition, the Company holds certain investment securities with fair values totaling $302.5 million which are subject to repricing on not less than a quarterly basis.

Asset Quality and Credit Loss Provisioning

During the three months ended March 31, 2025, the Company recorded a provision for credit losses of $3.7 million, as compared to $1.7 million during the trailing quarter, and $4.3 million during the first quarter of 2024.

Total provision for credit losses | 3,728 |  |  | 1,702 |  |  | 4,305 |  |  |  |  |  |  |  |  |  |  |  |  |  |

The provision for credit losses on loans of $2.7 million recorded during the current quarter resulted from a net increase of $4.9 million in reserves on individually evaluated loans or loan relationships, which were partially offset by net recoveries ($0.3 million) and decreases in qualitative factors attributed to general improvement in observable economic indicators.
The $4.9 million increase in individually evaluated reserves was largely attributed to the migration of previously identified criticized credits that have more recently transitioned to an elevated risk grade and / or non-accrual status. Management believes the provisioning for these individually analyzed credits is sufficient relative to expected future charge-offs, if any. As it relates to improvements in general economic indicators, Management notes that through the end of the current quarter, actual and forecasted trends including, but not limited to, unemployment, gross domestic product, and corporate borrowing rates continued to evidence stability and were supportive of general economic expansion, relative to the trailing period ended December 31, 2024, which is aligned with the Company's direct experiences with borrowers.
The allowance for credit losses (ACL) was $128.4 million or 1.88% of total loans as of March 31, 2025. The Company utilizes forecast data that continues to evolve, but included an improving outlook for both unemployment and GDP, among other factors, leading up to the balance sheet date. Core inflation is observed as stabilized rather than decreasing and prices remain elevated relative to wage increases, as reflected by higher living costs such as housing, energy and general services. Possible steepening of the yield curve or actions by the Federal Reserve to cut rates during 2025 and beyond may help further improve this outlook overall, but the uncertainty associated with the extent and timing of these potential reductions has inhibited a material change to monetary policy assumptions. Furthermore, geopolitical policy risks remain elevated, which may lead to further negative effects on domestic economic outcomes. The uncertainties related to the nature, duration and potential economic impact of proposed tariffs, present challenges in correlating potential improvement of credit risks within the Company's loan portfolio. Therefore, in conjunction with most economists' belief that tariffs will have a generally negative impact on the economy as a whole, management continues to believe that certain credit weaknesses are 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 $12.0 million during the quarter ended March 31, 2025, to $44.8 million, as compared to $32.7 million at December 31, 2024. The majority of loans identified as past due are well-secured by collateral, and approximately $27.8 million are less than 90 days delinquent. Non-performing loans were $54.9 million at March 31, 2025, an increase of $10.8 million from $44.1 million as of December 31, 2024, and an increase of $20.6 million from $34.2 million as of March 31, 2024. Management continues to proactively work with these borrowers to identify actionable and appropriate resolution strategies which are customary for the industries. Of the $54.9 million loans designated as non-performing as of March 31, 2025, approximately $19.0 million are current or less than 30 days past due with respect to payments required under their existing loan agreements.

The ratio of classified loans to total loans of 1.94% as of March 31, 2025, increased 20 basis points from December 31, 2024, and increased 82 basis points from the comparative quarter ended 2024. The change in criticized loans outstanding as compared to the trailing quarter totaled $9.5 million. The Company's combined criticized loan balances totaled $238.4 million as of March 31, 2025, an increase of $54.0 million from March 31, 2024. Loans with the risk grade classification substandard increased by $14.2 million over the trailing quarter without any material changes in the mix of underlying collateral type.
Management continues to proactively assess the repayment capacity of borrowers that will be subject to rate resets in the near term. To date this analysis as well as management's observations of loans that have experienced a rate reset, have resulted in an insignificant need to provide concessions to borrowers.
As of March 31, 2025, other real estate owned consisted of 9 properties with a carrying value of approximately $2.7 million, compared to 10 properties with a carrying value of approximately $2.8 million as of December 31, 2024. Non-performing assets of $57.5 million at March 31, 2025, represented 0.59% of total assets, a change from $46.9 million or 0.48% and $36.7 million or 0.37% as of December 31, 2024 and March 31, 2024, 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 are expected to be amortized over the life of the loans. As of March 31, 2025, the unamortized discount associated with acquired loans totaled $18.3 million, which, when combined with the total allowance for credit losses above, represents 2.25% of total loans.

The Company incurred $1.1 million in losses related to the sale of investment securities during the quarter on proceeds totaling $30.0 million, offset by excess cash flows from death benefit proceeds of $1.2 million recorded within other income. Additionally, service charge and fee income declined by $0.3 million during the quarter, as transactional interchange and service fee volume tends to decline against the elevated consumer spending levels usually observed during the fourth quarter.

Total salaries and benefits expense, the largest non-interest expense component, increased by $1.5 million or 4.3%, due to increases in headcount within targeted growth markets aligned with the Company's organic growth objectives, the seasonal impacts associated with the start of a new payroll tax calendar, and decreased production volumes for deposits and loans as compared to the comparable quarter. Other non-interest expense line items evidenced broad based incremental reductions consistent with management's efficiency and scaling initiatives.

Total salaries and benefits expense increased by $2.6 million or 7.4%, reflecting the increase of $1.4 million in salaries, largely the result of routine merit increases and more recently strategic hiring focused on loan and deposit production; incentive compensation costs also increased by $0.8 million, reflecting elevated levels of production in both loans and deposits during the first quarter of 2025, as compared to 2024.

Provision for Income Taxes

The Company’s effective tax rate was 25.3% for the quarter ended March 31, 2025, as compared to 25.3% for the quarter ended December 31, 2024, and 26.4% for the quarter ended March 31, 2024. 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)

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:
