*"Good is the enemy of great."* – Jim Collins

"I am proud to announce the strongest quarterly earnings in our history!" stated Kevin McPhaill, CEO and President. "Thanks to the dedication of our banking teams and a laser focus on expense control, we are delivering impressive results, as demonstrated by a 10 percent earnings per share growth in 2025. I am even more optimistic about our 2026 strategy to deepen lending and deposit connections with businesses and individuals in our communities, enhance processes and technology, and maintain overall expenses. Our commitment to make every community we serve better starts with our exceptional team working together toward a common purpose. I am excited about our opportunities for improvement not only in 2026, but well into the future!" concluded Mr. McPhaill.

**Financial Highlights**

**Quarterly Changes (comparisons to the fourth quarter of 2024)**

● Quarterly net income at $12.9 million increased by $2.5 million, or 24%. This robust net income growth was primarily attributable to a $3.3 million decrease in the provision for credit losses and a 5.3% increase in net interest income, partially offset by slightly unfavorable variances for noninterest income and noninterest expense.

● Pre-tax pre-provision for credit losses income (see non-GAAP financial measures table) was $16.3 million, an increase of $1.3 million, or 8%.

● Net interest income increased by $1.6 million, or 5%, due to a 14 basis point increase in net interest margin which in turn was driven by a 26 basis point decrease in the cost of interest-bearing liabilities.

● The $3.3 million decrease in the provision for credit losses was due to a $1.5 million favorable release of individual reserves in the fourth quarter of 2025 from three separate relationships, while provision for credit losses in the fourth quarter of 2024 included an increase of $2.5 million in individual reserves.

● Noninterest expense increased by $0.2 million, or less than 1%, due mostly to legal expenses related to loan workouts that are expected to wind down in early 2026. Management is focused on expense control as noted by the slight decline in overall noninterest expense for the full year 2025 as compared to 2024. This has been partially accomplished by a reduction of 20 full time equivalent employees throughout 2025, as well as the closure of a branch in the fourth quarter of 2025.

**Full-Year of 2025 Changes (comparisons to the year ended 2024)**

● Net income increased $1.8 million, or 4%, to $42.3 million, primarily driven by an increase of $4.7 million in net interest income, offset by an increase in provision for credit losses of $1.3 million and a decrease in noninterest income of $0.9 million, while noninterest expense remained relatively flat.

● Diluted EPS increased by 10% to $3.11 per share due to higher net income coupled with the repurchase of 1,024,792 shares during 2025.

● Pre-tax pre-provision for credit losses income (see non-GAAP financial measures table) increased $3.8 million, or 6%, to $62.4 million.

------

Sierra Bancorp Financial Results

February 2, 2025

● The $4.7 million increase in net interest income was due mostly to an increase of 9 basis points in net interest margin to 3.75%. The increase in net interest margin was primarily due to a 26 basis point favorable decline in the cost of interest-bearing liabilities. Although the yield on interest-earning assets declined by 10 basis points, margin stability was preserved through a $40.9 million increase in average balances.

● The provision for credit losses was $6.1 million, an increase of $1.3 million, primarily due to the workout of a single agricultural loan relationship throughout 2025, which resulted in charge-offs of $7.5 million.

● Noninterest income decreased by $0.9 million, or 3%, driven by an unfavorable change of $1.1 million in non-recurring gains, as well as a decrease in service charges on deposit accounts of $0.7 million. These decreases were partially offset by an increase in gains recorded on life insurance proceeds during 2025.

● Noninterest expense decreased $0.1 million, or 0.1%, during 2025 as a result of a strategic focus on expense management.

● Included in the line-item changes from the same period in 2024 was the decrease of $0.5 million in income from corporate-owned life insurance income invested which partially offset the $0.6 million decrease in deferred compensation costs.

**Balance Sheet Changes (comparisons to December 31, 2024)** 

● Total assets increased by $215.8 million, or 6%, to $3.8 billion during 2025, due primarily to an increase in outstanding loan balances.

● Gross loans at amortized cost increased $215.4 million, or 9%, due to a $191.9 million increase in mortgage warehouse line utilization, a $33.1 million increase in commercial real estate loans, a $14.2 million increase in other commercial loans, and an $8.9 million increase in other construction/land loans. This favorable growth was partially offset by decreases of $23.0 million in residential real estate loans, $9.2 million in farmland loans, and $0.5 million in consumer loans.

● Deposits totaled $2.9 billion at December 31, 2025, representing an annual decrease of $15.2 million, or 0.5%. The decline in deposits came mostly from decreases of $71.4 million in higher-cost customer time deposits, partially offset by an increase in brokered deposits of $45.1 million and smaller increases in customer transaction accounts.

● Total borrowings increased by $245.0 million due primarily to a shift in interest rates allowing the Company to fund mortgage warehouse balances with lower-cost overnight funding versus short term brokered deposits. Mortgage warehouse hit record balances at December 31, 2025, at $518.3 million. The Company primarily uses short-term wholesale funding for mortgage warehouse given its short-term nature. At December 31, 2025, the Company had $320.9 million in brokered deposits and $222.7 million in shorter-term wholesale funding.

**INCOME STATEMENT HIGHLIGHTS**

**Net Interest Income**

Net interest income was $32.0 million for the fourth quarter of 2025, a $1.6 million increase, or 5%, over the fourth quarter of 2024. For the year ended December 31, 2025, net interest income increased $4.7 million, or 4%, to $124.7 million, relative to the same period in 2024. Net interest income remained relatively unchanged compared to the prior linked quarter.

For the fourth quarter of 2025, the yield on earning assets was 4 basis points lower as compared to the same period in 2024, which offset the increase in average interest-earning assets of $33.1 million. The decrease in yield was mostly due to the decrease in both yields and balances on variable rate collateralized loan obligations (CLOs) due to the 75 basis points in fed funds rate cuts from September through December 2025. This was partially offset by an increase of 14 basis points in loan yields, primarily due to increases in real estate and commercial and industrial yields.

Further, there was a favorable 26 basis point decrease in the cost of our interest-bearing liabilities for the same period. The favorable decline in funding costs was due to a significant reduction in the cost of customer time deposits and brokered deposits, compounded by a decrease of $138.8 million in the average balance of those accounts. Lower-cost deposit

categories, including savings accounts, NOW, and money market accounts, experienced modest net increases in average balances and little change in funding costs, resulting in an immaterial impact on net interest income.

Net interest income for the comparative annual periods increased $4.7 million, or 4%, due mostly to a decrease in interest expense of $5.6 million, driven by a decrease in cost of interest-bearing liabilities of 26 basis points. Consistent with the quarterly comparison, the primary drivers were lower rates paid on customer time deposits and brokered deposits, along with a $93.8 million decline in average balances in those accounts. This was partially offset by an increase of $42.2 million in borrowed funds average balances with little change in the overall funding costs.

Investment securities average balances declined by $123.0 million during the comparative annual period, primarily due to an increase in paydowns and early calls of CLOs, while loan balances grew by $183.9 million driven by strong production in mortgage warehouse, commercial real estate, and commercial and industrial lending. The yield on interest-earning assets declined 10 basis points, and while the higher level of interest-earning assets partially offset the lower yield, the net effect had a moderate impact on interest income.

Our net interest margin was 3.79% for the fourth quarter of 2025 which was 14 basis points higher than the fourth quarter of 2024. The yield of interest-earning assets decreased 4 basis points for the fourth quarter of 2025, as compared to the same quarter for 2024, and the cost of interest-bearing liabilities decreased 26 basis points. The favorable shift in costs led to an overall 14 basis point increase in net interest margin in the fourth quarter of 2025, compared to the same period in 2024. Compared to the prior annual period, the yield on interest earning assets declined 10 basis points while the cost of interest-bearing liabilities decreased by 26 basis points for an overall increase in net interest margin of 9 basis points to 3.75%

**Credit Loss Expense** 

The Company recorded a reversal of $0.8 million in credit loss expense related to loans in the fourth quarter of 2025 and recognized $6.1 million of credit loss expense related to loans for the full year of 2025, compared to credit loss expense of $2.3 million and $4.6 million, respectively, for the same periods in 2024. The $0.8 million release in allowance for credit losses during the fourth quarter of 2025 was due mostly to the $1.5 million release of specific reserve on loans individually evaluated, partially offset by higher reserve on loans collectively evaluated. The higher credit loss expense in 2025 was due mostly to increased provision related to a single agricultural lending relationship.

Compared to the prior linked quarter, the credit loss expense related to loans decreased by $4.5 million due mostly to the establishment of a $3.5 million specific reserve for a single agricultural relationship in the third quarter of 2025, followed by a net $0.8 million release of allowance in the fourth quarter of 2025. During the fourth quarter of 2025, $2.3 million of the $3.5 million specific reserve established in the third quarter of 2025 was charged off and $1.2 million was released, along with the release of an additional $0.3 million in specific reserves on two separate relationships. The fourth quarter of 2025 release of reserves related to loans individually evaluated were partially offset by higher reserves on loans collectively evaluated.

The net unrealized loss position on the Bank's investment securities was attributable to changes in interest rates and volatility in the financial markets and not a result of an expected credit loss.

**Noninterest Income**

Total noninterest income reflects a $0.2 million decline, or 2%, for the quarter ended December 31, 2025, as compared to the same quarter in 2024, and a $0.9 million, or 3%, decrease for the full year 2025 as compared to the same period in 2024. The decrease in the quarterly comparison was primarily driven by a decrease in gains recorded on life insurance proceeds and on the sale of investment securities. This decrease was due to a small gain on life insurance proceeds recorded in the fourth quarter of 2024 with no like transactions in the fourth quarter of 2025. The full year decrease was driven by an unfavorable change in nonrecurring gains and a decrease in service charges on deposit accounts of $0.7 million. These decreases were partially offset by an increase in gains recorded on life insurance proceeds during 2025.

The majority of this deferred compensation expense is reported as professional fees under directors' fees as it is related to deferral of past directors' fees. Specifically, $0.1 million for the fourth quarter of 2025 and $1.0 million for the full year of 2025 were recorded as directors' fees within the professional fees expense line item. The related tax benefit associated with tax-free earnings with tax-deductible expense totaled $0.1 million during the fourth quarter of 2025 and $0.8 million for the full year 2025.

Total noninterest expense remained relatively flat for the annual comparison with a 0.1% decline overall due to a strategic initiative to manage expenses. While noninterest expense increased by $0.2 million in the fourth quarter of 2025 as compared to the fourth quarter of 2024, the change was due mostly to higher legal fees associated with workout loans.

Salaries and Benefits expense declined by $0.1 million, or 1%, in the fourth quarter of 2025, as compared to the fourth quarter of 2024, and was $0.7 million higher, or 1%, for the year ended 2025, compared to the same period in 2024. For the full year of 2025, overall base salary and incentives were relatively unchanged. The increase in costs was mostly due to higher employee benefits, driven mostly by higher insurance costs. Full-time equivalent employees decreased by 20 to 465 full-time equivalent employees at December 31, 2025, as compared to 485 at December 31, 2024. The reduction in staff mostly occurred in the fourth quarter of 2025 and is expected to have a positive impact on overall compensation expense in 2026.

Other noninterest expense increased $0.2 million for the fourth quarter of 2025 and decreased $0.9 million for the year ended 2025, as compared to the same periods in 2024. For the year-over-year comparison, the favorable variance was the result of reductions in directors' deferred compensation expense and overall fraud and debit card losses.

The Company's provision for income taxes was 24.8% of pre-tax income in the fourth quarter of 2025, compared to 17.7% in the fourth quarter of 2024, and 24.9% of pre-tax income for the year ended December 31, 2025, as compared to 24.7% for the year ended 2024. The lower effective tax rate in the fourth quarter of 2024 was due to an increase in the net benefit from low-income housing tax credit investments.

**Balance Sheet Summary**

The $215.8 million, or 6%, increase in total assets during the year ended 2025, was mostly a result of loan growth of $215.4 million during the year. Investment securities declined $45.3 million, primarily from runoff and calls of variable rate CLOs, offset by purchases of mortgage-backed securities and corporate bonds.

The $215.4 million increase in gross loans at amortized cost, as compared to December 31, 2024, was a result of organic growth led by a $191.9 million strategic increase in outstanding mortgage warehouse balances. The remaining increases came from $33.1 million in commercial real estate loans, $14.2 million in other commercial loans, and $8.9 million in other construction/land loans, partially offset by decreases of $23.0 million in residential real estate loans, $9.2 million in farmland loans, and $0.5 million in consumer loans.

As indicated in the loan roll forward below, new credit extended (excluding mortgage warehouse) for the fourth quarter of 2025 of $26.8 million represented a $21.3 million decrease compared to the prior linked quarter, and a $53.1 million decline relative to the same period in 2024. New credit extended (excluding mortgage warehouse) decreased $27.1 million for the full year of 2025 as compared to 2024, as a result of a shift in lending focus away from agricultural lending as well as a more competitive market for loans. Loan pay-downs, maturities, and amortization have remained stable over the quarterly and linked quarter comparisons.

&nbsp;&nbsp;&nbsp;&nbsp;(1) Change does not include new balances on lines of credit extended during the respective periods as such balances are included as part of "New credit extended" line above.

Unused commitments, excluding mortgage warehouse and overdraft lines, were $236.4 million at December 31, 2025, compared to $256.9 million at December 31, 2024. Total line utilization, excluding mortgage warehouse and overdraft lines, was 61% at December 31, 2025, and 57% at December 31, 2024. Including mortgage warehouse utilization, overall utilization was 62% at December 31, 2025, as compared to 51% at December 31, 2024. Mortgage warehouse utilization increased to 68% at December 31, 2025, as compared to 51% at December 31, 2024. Due to an increase in line utilization, offset by new customer growth, total mortgage warehouse availability decreased to $247.7 million at December 31, 2025, as compared to $311.6 million at December 31, 2024.

Deposit balances declined by $15.2 million, or 0.5%, during the year ended 2025 due primarily to a decline in customer time deposits. Core non-maturity deposits increased by $11.1 million, or 1%, while customer time deposits decreased by $71.4 million, or 13%. The decline in customer time deposits was due primarily to a strategic shift in our CD rate strategy in order to lower overall deposit costs. Brokered deposits increased by $45.1 million, or 16%. The increase in brokered deposits was primarily to fund increases in mortgage warehouse lines. As shorter term rates fell in the later part of the year, approximately $125 million of the $320 million of brokered deposits at December 31, 2025, were one-way buys through IntraFi in lieu of traditional brokered certificates of deposits. Overall noninterest-bearing deposits as a percentage of total deposits at December 31, 2025, remained steady at 34.6%, as compared to 34.8% at December 31, 2024. Other interest-bearing liabilities of $433.6 million at December 31, 2025, consist of $130.9 million in customer repurchase agreements, $222.7 million in overnight borrowings, and $80.0 million of term FHLB borrowings, as compared to $108.9 million in customer repurchase agreements, and $80.0 million of term FHLB borrowings at December 31, 2024.

Overall uninsured deposits are estimated to be approximately $702.6 million, or 25% of total deposit balances, excluding public agency deposits that are subject to collateralization through a letter of credit issued by the FHLB. In addition, uninsured deposits of the Bank's customers are eligible for FDIC pass-through insurance if the customer opens an IntraFi Insured Cash Sweep (ICS) account or a reciprocal time deposit through the Certificate of Deposit Account Registry System (CDARS). IntraFi allows for up to $285 million per customer of pass-through FDIC insurance, which would more than cover each of the Bank's deposit customers if such customer desired to have such pass-through insurance. The Bank maintains a diversified deposit base with no significant customer concentrations and does not bank any cryptocurrency companies. At December 31, 2025, the Company had approximately 117,000 accounts, and the 25 largest deposit balance customers had balances of approximately 9% of overall deposits*.* During the fourth quarter of 2025, except for seasonal fluctuations in the normal course of business, there have been no material changes in the composition of our 25 largest deposit balance customers.

The Company continues to have substantial liquidity. At December 31, 2025, and December 31, 2024, the Company had the following sources of primary and secondary liquidity (dollars in thousands, unaudited):

Total capital of $364.9 million at December 31, 2025, reflects an increase of $7.6 million, or 2%, relative to year-end 2024. The increase in equity during the year ended December 31, 2025, was primarily due to $42.3 million in net income and a $8.1 million favorable swing in accumulated other comprehensive income (loss) partially offset by $13.7 million in dividends paid, and $30.8 million in share repurchases. The remaining difference was related to stock options exercised and restricted stock activity during the year.

**Asset Quality**

Total nonperforming assets, comprised of nonaccrual loans and foreclosed assets, decreased by $4.9 million to $14.8 million for the year ended December 31, 2025, as compared to December 31, 2024. At December 31, 2025, nonaccrual assets were comprised primarily of two agricultural relationships totaling $13.0 million and a single other real estate owned property of $1.6 million. The Company's ratio of nonperforming loans to gross loans improved to 0.52% at December 31, 2025, from 0.84% at December 31, 2024. This favorable change in asset quality resulted from a decrease in nonaccrual loan balances, primarily as a result of the charge-off of $7.5 million from one agricultural loan relationship. Foreclosed assets increased to $1.6 million for the year ended December 31, 2025, due to the transfer of one commercial real estate loan previously classified as nonaccrual. All the Company's nonperforming loans are individually evaluated for credit loss quarterly and management believes the established nominal allowance for credit loss on such loans was appropriate at December 31, 2025.

Loans with payments past due 30 days or more and still accruing increased to $6.8 million at December 31, 2025, an increase of $6.6 million compared to the prior quarter end and an increase of $5.5 million compared to the prior year end. Of the $6.8 million past due and still accruing, $3.8 million is due to maturities in process of renewal, and another $2.0 million was related to a single agricultural real estate loan that was brought current on January 9, 2026.

The Company's allowance for credit losses on loans was $21.5 million at December 31, 2025, as compared to a balance of $24.8 million at December 31, 2024. The decline in the Company's allowance in total dollar amount and as a percentage of total loans was primarily the result of the workout of the single, large agricultural loan relationship resulting in a $7.5 million charge-off. At December 31, 2024, the Company's specific reserves were primarily comprised of a $3.0 million specific reserve on this same loan relationship. At December 31, 2025, there was an inconsequential specific reserve on this loan relationship. The allowance was 0.84% of total loans at December 31, 2025, and 1.07% of total loans at December 31, 2024. The Company experienced higher net charge offs during the year, offset by the release of $1.6 million in specific reserves on three separate other commercial loans in the fourth quarter of 2025. The following tables highlight the coverage ratios by loan category at December 31, 2025, September 30, 2025, and December 31, 2024:

The allowance for credit losses on loans and leases was 0.84% of gross loans at amortized cost at December 31, 2025, and 1.07% of gross loans at December 31, 2024. The largest increase in loan balances was from mortgage warehouse lines, which has the lowest reserve rate in the allowance for credit losses at 0.13%. Mortgage warehouse lines historically have incurred nominal losses and, therefore, have a significantly lower reserve than the other categories of loans. Further, our residential real estate loans are comprised primarily of jumbo residential loans purchased in 2021 and early 2022 with very strong underwriting. Given the underlying strength of this portfolio, the allowance associated with our residential real estate loans was 0.39% at December 31, 2025. The allowance as a percentage of gross loans, exclusive of mortgage warehouse lines and residential mortgage loans, was 1.16% at December 31, 2025, as compared to 1.39% at September 30, 2025, and 1.39% at December 31, 2024.

The largest loan segment of commercial real estate continues to maintain a coverage ratio at or above 1.18%. As described above, the significant decrease in the coverage ratio for other commercial loans was due to the $2.3 million partial charge-off and $1.2 million release of the remaining specific reserve on a single $3.5 million agricultural production loan relationship.

Management's detailed analysis indicates that the Company's allowance for credit losses on loans should be sufficient to cover life of loan credit losses on loan portfolio balances outstanding as of December 31, 2025, but no assurance can be given that the Company will not experience substantial future losses in excess of the current allowance for credit losses on loans.
