 SIERRA BANCORP REPORTS FIRST QUARTER 2024 RESULTS
 Porterville, Calif. – (BUSINESS WIRE) – Sierra Bancorp (Nasdaq: BSRR), parent of Bank of the Sierra, today
 announced its unaudited financial results for the quarter ended March 31, 2024. Sierra Bancorp reported consolidated net
 income of $9.3 million, or $0.64 per diluted share, for the first quarter of 2024 compared to $8.8 million, or $0.58 per
 diluted share, in the first quarter of 2023. The favorable variance in net income came largely from a $0.6 million increase
 in net interest income due mostly to a $0.7 million decline in other borrowing costs as a result of the strategic balance
 sheet restructuring during the quarter. The Company's return on average assets and return on average equity was 1.06%
 and 11.09%, respectively, in the first quarter of 2024 as compared to 0.97% and 11.53%, respectively, in the first quarter

 “Our first quarter results demonstrate our strength and commitment to banking fundamentals coupled with strategic
 repositioning, especially in this challenging rate environment that continues to affect the banking industry,” stated Kevin
 McPhaill, CEO and President. “Following the completion of our balance sheet restructuring last quarter, our return on
 assets and net interest margin both showed strong improvement this quarter. In addition, both our capital and liquidity
 positions strengthened. We also grew outstanding loans by 3.2% during the quarter while maintaining strong total and
 low-cost deposits. This is a direct result of the efforts of our banking team! Our bankers continue to understand the
 importance of relationship-based community banking and we are grateful for our loyal customers and communities. We
 are excited for the opportunities ahead in 2024 and beyond!” McPhaill concluded.
 Quarterly Changes (comparisons to the first quarter of 2023)
 • Net income for the first quarter of 2024 increased $0.6 million, or 7%, to $9.3 million due primarily to an increase
 in net interest income of $0.6 million. Additionally, the favorable change in the credit loss expense on loans and
 improvements in noninterest income, was mostly offset by higher noninterest expenses.
 • The $0.6 million increase in net interest income for the quarter was driven by a 15 basis point increase in the net
 interest margin due to higher yields on investments and lower costs of borrowings, partially offset by higher
 deposit costs.
 • Noninterest income for the first quarter of 2024 as compared to the same period in 2023 increased $2.0 million
 or 31%. There was a favorable variance of $1.0 million in bank owned life insurance (BOLI), a gain on the
 sale/leaseback of two bank owned branch buildings for $3.8 million, increases in service charges and fees on
 deposit accounts for $0.3 million or 6%, offset by a loss on the sale of bonds from a balance sheet restructure for
 $3.0 million.
 Linked Quarter Changes (comparisons to the three months ended December 31, 2023)
 • Net income increased by $3.0 million, or 48%, driven mostly by a $3.4 million decline in the provision for credit
 losses. The higher provision for credit losses in the three months ended December 31, 2023, was due to a $2.3
 million charge-off related to commercial real estate.
 • Net interest income increased by $0.8 million, or 3%, during the quarter due mostly to higher yields on
 investments and lower costs of borrowing due to the strategic balance sheet restructuring, as well as growth in
 mortgage warehouse loan income. These favorable variances were partially offset by higher deposit costs.
 • Other expenses were $0.4 million higher in the quarter due mostly to higher deferred directors fee expense of
 $0.8 million (which was offset by higher BOLI income).
 Balance Sheet Quarterly Changes (comparisons to December 31, 2023)
 • Total assets decreased $176.7 million, or 5% to $3.6 billion, during the first three months of 2024, due mostly to
 a strategic sale of lower yielding investment securities, with funds received used to paydown higher cost
 borrowings.
 • Gross loans increased $66.8 million due to a $87.6 million increase in mortgage warehouse line utilization.
 • Deposits increased by $85.8 million, or 3%. The growth in deposits came from brokered deposits, as overall
 customer deposits decreased $50.9 million.

 INCOME STATEMENT HIGHLIGHTS
 Net Interest Income
 Net interest income was $28.7 million for the first quarter of 2024, an increase of $0.8 million, or 3%, as compared to the
 fourth quarter of 2023 and an increase of $0.6 million, or 2%, as compared to the first quarter of 2023. This increase in
 interest income was due primarily to a $2.3 million decrease in interest expense due to the reduction in borrowed funds
 facilitated by a balance sheet restructuring, partially offset by a related decline in interest income on investments of $1.5
 million, or 3%, due to the sale of low yielding investments.
 For the first quarter of 2024 as compared to the same quarter in 2023, the $3.5 million increase in interest income is due
 primarily to a $56.8 million increase in average loan balances, as well as a 39 basis point increase in yield. However, this
 was partially offset by a $3.0 million increase in interest expense due to the movement of deposits from lower cost
 transaction accounts to higher cost time deposits including wholesale brokered deposits. Deposit costs increased 82 basis
 points in the first quarter of 2024 as compared to the same quarter in 2023, while there was a 35 basis points decrease in
 the cost of borrowed funds.

 At March 31, 2024, 54% (fair value) of the Investment portfolio are variable rate AA and AAA rated collateralized loan
 obligations (CLOs). These securities have a market yield of 7.22% with rates that adjust quarterly. At March 31, 2024,
 these CLOs have a net unrealized gain of $0.5 million. These securities account for 68% of the interest income on
 investments in the first quarter of 2024 and were mostly purchased in 2021 and 2022 when rates were at historical lows to
 complement our fixed-rate earning assets.
 At March 31, 2024, approximately 22% of the Bank’sloan portfolio is scheduled to mature or reprice within twelve months
 and an additional 13% that could reprice within three years. In addition, approximately $563.6 million, or 53.3%, of the
 securities portfolio consists of floating rate bonds that will reprice in less than 90 days.
 Interest expense was $12.2 million for the first quarter of 2024, a $2.3 million decrease, or 16%, from the linked quarter,
 and an increase of $3.0 million, or 32% from the same period in 2023. The decrease in the linked quarter comparison is
 attributable to the strategic balance sheet restructuring that resulted in a shift from being a net purchaser of Federal Funds
 at December 31, 2023, to maintaining excess funds at the Federal Reserve Bank at March 31, 2024. The increase in the
 quarterly comparison was primarily due to an increase in rates paid on customer variable rate Certificates of Deposits. The
 rate on the variable account is tied to a spread to the Wall Street Journal Prime Rate and varies from Prime minus 600
 basis points to Prime minus 375 basis points. During the twelve-month period from March 31, 2023, to March 31, 2024,
 the Prime rate increased 50 basis points.
 Our net interest margin was 3.62% for the first quarter of 2024, as compared to 3.31% for the linked quarter and 3.47%
 for the quarter ending March 31, 2023. While the yield of interest-earning assets increased 14 basis points for the first
 quarter of 2024 as compared to the linked quarter, the cost of interest-bearing liabilities decreased 20 basis points for the
 same period of comparison. The average balance of interest-earning assets decreased $175.4 million for the linked quarter
 while the decrease in interest-bearing liabilities was $168.8 million for the same period. The decrease in interest rates on
 a larger volume of interest-bearing liabilities (mostly higher cost borrowed funds) over the increase in yield on interestearning assets improved the net interest margin in the linked quarter.
 Provision for Credit Losses
 The Company recorded a provision for credit losses of $0.1 million in the first quarter of 2024, as compared to $3.5 million
 in the fourth quarter of 2023, and $0.3 million in the first quarter of 2023. The lower provision for credit losses in the first
 quarter of 2024 over the linked quarter was primarily due to the impact of one $2.3 million commercial real estate credit
 charged off in the fourth quarter of 2023. The decrease in provision in the first quarter of 2024 as compared to the same
 quarter in 2023 was a result of reduced quantitative reserves from an improved economic forecast coupled with lower loan
 balances in most categories. Some of the calculated reserve reduction was offset by higher net loan charge-offs, however
 the overall reserve for credit losses was $0.05 million higher at March 31, 2024, as compared to March 31, 2023.
 The Company did not record a provision for credit losses on available-for-sale debt securities. Although there were debt
 securities in an unrealized loss position, the declines in market values were primarily attributable to changes in interest
 rates and volatility in the financial markets and not a result of an expected credit loss.
 Noninterest Income
 Noninterest income increased by $0.5 million, or 7%, to $8.6 million in the first quarter of 2024 as compared to the linked
 quarter. Noninterest income increased by $2.0 million, or 31%, in the first quarter of 2024 as compared to the same quarter
 in 2023. The first quarter 2024 increase of $0.5 million, compared to the fourth quarter of 2023, is primarily due to net
 gains on the sale of branch properties that were a part of our sale/leaseback transaction and related securities sales strategy
 along with favorable changes in bank owned life insurance associated with deferred compensation plans. Partially
 offsetting these favorable variances were $0.3 million in service charges and fees decreases and lower life insurance death
 benefits.

 For the first quarter of 2024 compared to the same quarter in 2023, reasons for the increase were mostly the same although
 service charges and fees on deposit accounts increased by $0.3 million for the quarterly comparison instead of a decrease
 in the linked quarter comparison.
 Service charges and fees on customer deposit accounts declined by $0.3 million, or 4%, to $5.7 million in the first quarter
 of 2024 as compared to the fourth quarter of 2023. Lower seasonal analysis fees and lower debit card interchange fees
 were the primary drivers of the unfavorable variance. Service charges and fees were $0.3 million higher in the first quarter
 of 2024 as compared to the first quarter of 2023 due to higher ATM fees and higher overdraft-related fees.
 Noninterest Expense
 Total noninterest expense increased $0.4 million, or 2%, in the first quarter of 2024 as compared to the fourth quarter of
 2023 and increased $1.5 million, or 7%, compared to the first quarter of 2023. The primary driver of higher expense in the
 first quarter of 2024 is deferred directors’ fees as part of the Company’s deferred compensation plan. The higher deferred
 compensation expense was offset by higher bank-owned life insurance income, mostly due to fluctuations in underlying
 values of assets in the separate account BOLI policies that are designed to have similar assets to those in the deferred
 compensation plans.
 Salaries and benefits were $0.2 million lower in the first quarter of 2024 as compared to the fourth quarter of 2023 and
 $0.4 million higher than the first quarter of 2023. The decrease in the linked quarter was due to a strategic reduction in
 force to drive operational efficiencies. The increase in the year-over-year quarterly comparison is due to several factors,
 including merit increases for employees due to annual performance evaluations during the first quarter of 2024, higher
 payroll taxes in the first quarter, and severance payments of $0.9 million for the reduction in force initiative previously
 mentioned. Overall full-time equivalent employees were 487 at March 31, 2024, as compared to 485 at December 31,
 2023, and 500 at March 31, 2023.
 Occupancy expense was up $0.1 million for the linked quarters and up $0.7 million for the first quarter of 2024 as compared
 to the same quarter last year. The reason for the increases in both comparisons is mostly due to increased rent expense
 from the sale/leaseback transaction in December 2023.
 Other noninterest expense increased $0.5 million, or 6%, in the first quarter of 2024 as compared to both the fourth quarter
 of 2023 and the first quarter of 2023. The primary reason for the negative variance in the first quarter of 2024 over the
 same period in 2023 was increased FDIC assessment costs, and increased directors deferred compensation expense which
 is linked to the fluctuation in BOLI income, although lower advertising expenses and foreclosed asset costs mitigated some
 of this negative variance. In the first quarter of 2024 as compared to the fourth quarter of 2023, directors deferred
 compensation expense accounted for the increase, partially offset by lower advertising costs.
 The Company's effective tax rate was 26.3% in the first quarter of 2024 relative to 23.8% in the fourth quarter of 2023 and
 23.6% for the first quarter of 2023. The increase in the effective tax rate for the first quarter of 2024 over the linked quarter
 and as compared to the same period in 2023, is due to tax credits and tax-exempt income representing a smaller percentage
 of total taxable income.
 Balance Sheet Summary
 The $176.7 million, or 5%, decrease in total assets during the first quarter of 2024, is primarily a result of a $281.1 million
 decrease in investment securities, from the sale of bonds from the strategic securities transaction, partially offset by a $66.8
 million increase in gross loans and a $40.6 million increase in cash on hand.
 Gross loan balances increased $66.8 million, or 3%, during the first quarter of 2024. Although most loan categories
 declined modestly, mortgage warehouse line utilization increased $87.6 million or 75%. Larger loan category decreases
 include a $12.8 million decrease in other commercial loans.

 Over the past several years, the Company has strategically focused on reducing concentrations in commercial real estate,
 especially amongst areas management deemed to be higher risk, such as construction, office real estate, and hospitality.
 At March 31, 2024, the total regulatory CRE concentration ratio of total CRE over Tier 1 Capital plus allowance was
 248%. Further, the overall level of construction and land development lending had declined to 1% of regulatory capital
 plus allowance for credit losses at March 31, 2024. At March 31, 2024, our non-owner occupied commercial real estate
 includes $304 million of retail, $155 million of warehouse/industrial, $186 million of office, and $182 million of
 hospitality. Approximately 5% of the office real estate matures in less than two years.
 As indicated in the loan rollforward below, new credit extended for the first quarter of 2024 decreased $17.6 million over
 the same period in 2023 but increased $8.3 million for the linked quarter comparisons. For the first three months ended
 2024, we had $30.8 million in loan paydowns and maturities, along with a $24.9 million decrease in line of credit
 utilization, counterbalanced by an $87.6 million increase in mortgage warehouse utilization.

 Gross loans ending balance $ 2,156,864 $ 2,090,075 $ 2,033,968
 Line utilization, unused commitments, excluding mortgage warehouse and overdraft lines, were $234.4 million at March
 31, 2024, compared to $203.6 million at December 31, 2023. Total utilization excluding mortgage warehouse and overdraft
 lines was 58% at March 31, 2024, compared to 53% at December 31, 2023. Mortgage warehouse utilization was 50% at
 March 31, 2024, compared to 36% at December 31, 2023. The increase in mortgage warehouse utilization during the first
 quarter of 2024 was due to new customers in the mortgage warehouse product that ramped up their utilization.
 Deposit balances grew by $85.8 million, or 3%, during the first quarter of 2024 to $2.8 billion at March 31, 2024. Core
 non-maturity deposits decreased $56.7 million, or 3%, for the first three months of 2024, while customer time deposits
 increased by $5.9 million. Brokered deposits increased $136.6 million during the quarter. Overall noninterest-bearing
 deposits as a percent of total deposits decreased to 34.0% at March 31, 2024, compared to 37.0% at December 31, 2023,
 and from 35.3% at March 31, 2023.
 Overall uninsured deposits are estimated to be approximately $784.4 million, or 28% 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 account or a reciprocal time deposit through the Certificate of Deposit Account Registry System
 (CDARS). IntraFi allows for up to $150 million of combined 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 March 31, 2024, the Company had approximately 121,000 accounts and the 25 largest deposit balance customers had
 balances of less than 13% of overall deposits.
 Long-term debt at March 31, 2024, consisted of $49.3 million of subordinated debt. Subordinated debentures related to
 trust preferred securities were $35.7 million at both March 31, 2024, and December 31, 2023.
 Customer repurchase agreements increased from $107.1 million at December 31, 2023, to $121.9 million at March 31,
 2024. Customer repurchase agreements provide collateral for customers that sweep excess deposit balances each day into
 a separate repurchase agreement account where the Company effectively sells certain government bonds to customers

 daily and then repurchases the same bonds on the next business day. Although these accounts are not deposits and are not
 FDIC insured, they provide customers with larger account balances the ability to have their account secured with collateral.
 Other borrowings declined $280.5 million to $80.0 million at March 31, 2024, from $360.5 million at December 31, 2023,
 and consist of term FHLB advances. The decline in other borrowings is due mostly to a balance sheet restructuring in
 which the Company sold bonds with an average book yield of 2.61% to paydown borrowed funds at an average rate of
 5.52%.
 The Company continues to have substantial liquidity. At March 31, 2024, and December 31, 2023, the Company had the
 following sources of primary and secondary liquidity (dollars in thousands):
 Primary and secondary liquidity sources March 31, 2024 December 31, 2023
 Cash and cash equivalents $ 119,244 $ 78,602
 Unpledged investment securities 555,766 792,965
 Excess pledged securities 316,889 382,965
 FHLB borrowing availability 676,829 586,726
 Unsecured lines of credit 504,785 374,785
 Funds available through fed discount window 376,216 392,034
 Totals $ 2,549,729 $ 2,608,077
 Total capital of $345.1 million at March 31, 2024, reflects an increase of $7.0 million, or 2%, compared to December 31,
 2023. The increase in equity during the first quarter of 2024 is due to net income of $9.3 million, offset by a $3.4 million
 dividend paid to shareholders, $3.3 million in share repurchases, and a $4.1 million favorable swing in other
 comprehensive income/loss due principally to changes in investment securities’ fair value. The remaining difference is
 related to equity compensation recognized during the quarter.
 Asset Quality
 Total nonperforming assets, comprised of non-accrual loans and foreclosed assets, increased by $6.2 million, or 78%,
 during the first quarter of 2024. The increase resulted from an increase in non-accrual loans, primarily as a result of one
 dairy industry real estate secured loan. This loan was written down by $0.4 million and no further allowance for credit
 losses was deemed necessary on this loan. The Company's ratio of nonperforming assets to loans plus foreclosed assets
 increased to 0.66% at March 31, 2024, from 0.38% at December 31, 2023, due primarily to the one dairy loan previously
 mentioned. All of the Company's nonperforming assets are individually evaluated for credit loss quarterly and management
 believes the established allowance for credit loss on such loans is appropriate.
 Overall delinquent loans increased from $1.9 million at March 31, 2023, to $15.6 million at March 31, 2024. This is
 primarily due to one agricultural production loan and one commercial real estate loan both currently written down to the
 current fair market value of the collateral.
 The Company's allowance for credit losses on loans was $23.1 million at March 31, 2024, as compared to $23.5 million
 at December 31, 2023, and $23.1 million at March 31, 2023. The allowance was 1.07% of total loans at March 31, 2024,
 1.12% of total loans at December 31, 2023, and 1.14% of total loans at March 31, 2023. Management's detailed analysis
 indicates that the Company's allowance for credit losses on loans should be sufficient to cover credit losses for the life of
 the loans outstanding as of March 31, 2024, but no assurance can be given that the Company will not experience substantial
 future losses relative to the size of the credit loss allowance for loans.
