TriCo Bancshares (NASDAQ:TCBK):

Executive Commentary:

"The strong performance trajectory which we close 2025 and start 2026 gives us good reason to be optimistic about our future. TriCo's foundation, built with exceptional employees and customers, consistently allows us to navigate a broad range of challenges and opportunities with confidence. Execution of our long-term strategies remain our primary focus, and we believe that alignment between the current economic outlook and our market positioning will be beneficial to the realization of our priorities," said Rick Smith, Chairman and CEO.

Peter Wiese, EVP and CFO added, "The expansion of both net interest income and net interest margin, despite recent Federal Funds rate cuts, was certainly a highlight of the quarter and, given the slope of the yield curve, we continue to expect incremental improvement through 2026. While we also held expense growth to a minimum during 2025 (approximately 3%), year over year expense growth in 2026 is likely to accelerate (5%), but should still allow for positive operating leverage."

Balance Sheet Data

Total loans outstanding were $7.1 billion as of December 31, 2025, an increase of $342.6 million or 5.1% over December 31, 2024, and an increase of $104.3 million or 6.0% annualized as compared to the trailing quarter ended September 30, 2025. Investments decreased by $13.7 million and $194.2 million for the three and twelve month periods ended December 31, 2025, respectively, and ended the quarter with a balance of $1.84 billion or 18.8% of total assets. Quarterly average earning assets to quarterly total average assets was 91.9% on December 31, 2025, compared to 91.8% at December 31, 2024. The loan-to-deposit ratio was 86.1% on December 31, 2025, as compared to 83.7% at December 31, 2024. The Company did not utilize brokered deposits during 2025 or 2024 and continues to rely on organic deposit customers to fund cash flow timing differences.

Total shareholders' equity increased by $23.7 million during the quarter ended December 31, 2025, as net income of $33.6 million and a $10.4 million decrease in accumulated other comprehensive losses were partially offset by $11.7 million in cash dividends on common stock and $8.9 million in share repurchase activity. As a result, the Company's book value increased to $41.07 per share at December 31, 2025, compared to $40.12 at September 30, 2025. 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 $31.52 per share at December 31, 2025, as compared to $30.61 at September 30, 2025. 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 $104.3 million or 6.0% on an annualized basis during the quarter ended December 31, 2025. During the quarter, loan originations/draws totaled approximately $502.8 million while payoffs/repayments of loans totaled $367.3 million, which compares to originations/draws and payoffs/repayments during the trailing quarter ended of $424.6 million and $377.1 million, respectively. Origination volume remains in-line in with the trajectory of historical levels, as interest rates continue to contract from the highs experienced in early 2025, and the macro-economic outlook remains optimistic for borrowers following the passage of tax and spending legislation that is expected to promote continued economic expansion. The activity within loan payoffs/repayments remained consistent with the trailing quarter and spread amongst numerous borrowers, regions and loan types.

Investment security balances decreased $13.7 million or 3.0% on an annualized basis during the quarter as a result of net prepayments/maturities of $56.7 million, and sales of $20.6 million, partially offset by net increases in the market value of securities of $14.7 million and purchases of $49.3 million. Investment security purchases were comprised of fixed rate agency mortgage-backed securities and collateralized loan obligations. 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 decreased by $70.6 million or 3.4% annualized during the period, which is consistent with the one-way sale of deposits totaling $72.9 million as of December 31, 2025. There were no deposit sales as of any comparable quarter end.

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

(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, 2025, increased $2.7 million or 3.0% to $92.5 million compared to $89.8 million during the three months ended September 30, 2025. Net interest margin totaled 4.02% for the three months ended December 31, 2025, an increase of 10 basis points from the trailing quarter. The increase in net interest income is primarily attributed to a $2 million reduction in interest expense on deposits, led by $1.3 million in benefit from savings deposit accounts. The net interest margin was further enhanced by reductions in interest expense on junior subordinated debt of $0.5 million as compared to the trailing quarter, following the early extinguishment of subordinated debt with a recorded book value of $59.9 million during the third quarter. In addition, the average balance of noninterest-bearing deposits increased by $52.0 million from the three-month average for the period ended September 30, 2025.

As compared to the same quarter in the prior year, average loan yields decreased 1 basis points from 5.78% during the three months ended December 31, 2024, to 5.77% during the three months ended December 31, 2025. The accretion of discounts from acquired loans added 5 basis points to loan yields during both quarters ended December 31, 2025 and December 31, 2024, respectively. The cost of interest-bearing deposits decreased by 28 basis points between the quarter ended December 31, 2025, and the same quarter of the prior year. In addition, the average balance of noninterest-bearing deposits increased by $13.9 million from the three-month average for the period ended December 31, 2024.
