The following is a summary of the components of the Company’s operating results and performance ratios for the periods indicated:

Total loans outstanding grew to $6.7 billion as of September 30, 2023, an organic based increase of 6.2% over the prior twelve months. As compared to June 30, 2023, total loans outstanding increased by $187.9 million or 11.5% annualized. Investments decreased to $2.33 billion as of September 30, 2023, an annualized decrease of 12.6% over the prior year quarter end. Quarterly average earning assets to quarterly total average assets were 91.7% on September 30, 2023, as compared to 91.6% and 92.0% at December 31, 2022, and September 30, 2022, respectively. The loan-to-deposit ratio was 83.8% on September 30, 2023, as compared to 80.6% and 73.0% at December 31, 2022, and September 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 decreased by $22.4 million during the quarter ended September 30, 2023, as a result of accumulated other comprehensive losses increasing by $44.0 million and cash dividend payments on common stock of approximately $10.0 million, offset by net income of $30.6 million. As a result, the Company’s book value was $32.18 per share at September 30, 2023, as compared to $32.86 and $29.71 at December 31, 2022 and September 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 $22.67 per share at September 30, 2023, as compared to $23.30 and $19.92 at December 31, 2022, and September 30, 2022, respectively. As noted above, despite the consistent retention of earnings in each quarter of the Company's history, recent changes in the balance of unrealized losses on available-for-sale investment securities, net of deferred taxes, has been the primary driver of decreases in tangible book value per share.

Loans outstanding increased by $187.9 million or 11.5% on an annualized basis during the quarter ended September 30, 2023. During the quarter, loan originations/draws totaled approximately $495.0 million while payoffs/repayments of loans totaled $308.0 million, which compares to originations/draws and payoffs/repayments during the trailing quarter ended of $456.0 million and $356.0 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. Investment security balances decreased $152.2 million or 24.5% on an annualized basis as the result of net prepayments, maturities, and purchases totaling approximating $89.7 million and net decreases in the market value of securities of $62.5 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 decreased by $85.7 million or 4.2% annualized during the period. Funding for the net cash outflows of loans, investment securities and deposits during the quarter were supported by a net increase of $145.3 million in short-term borrowings, which totaled $538.0 million at September 30, 2023.

Non-PPP loan balances increased as a result of organic activities by approximately $395.2 million or 6.3% during the twelve-month period ending September 30, 2023. Over the same period deposit balances have declined by $646.1 million or 7.5%. The Company has offset these declines through the deployment of excess cash balances, runoff of investment security balances, and proceeds from short-term FHLB borrowings. As of September 30, 2023 and June 30, 2023, short-term borrowings from the FHLB totaled $500.0 and $394.1 million and had a weighted average interest rate of 5.14 and 5.11%, respectively.

The Company's primary sources of liquidity include the following for the periods indicated:

At September 30, 2023, the Company's primary sources of liquidity represented 52.5% of total deposits and 175% 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 $124.0 million, including approximately $15.0 million in net unrealized losses. The Company did not utilize any brokered deposits during 2023 or 2022.

During the twelve-month period ended September 30, 2023, the Federal Open Market Committee's (FOMC) actions have resulted in an increase in the Fed Funds Rate by approximately 225 basis points. During the same period the Company's yield on total loans (excluding PPP) increased 65 basis points to 5.52% for the three months ended September 30, 2023, from 4.87% for the three months ended September 30, 2022. Moreover, the tax equivalent yield on the Company's investment security portfolio was 3.39%, an increase of 70 basis points from the 2.69% for the three months ended September 30, 2022. The cost of total interest-bearing deposits and total interest-bearing liabilities increased by 128 basis points and 154 basis points, respectively, between the three month periods ended September 30, 2023 and 2022. Since FOMC rate actions began in March 2022, the Company's cost of total deposits has increased 82 basis points which translates to a cycle to date deposit beta of 15.6%.

The Company continues to manage its cost of deposits through the use of various pricing and product mix strategies. As of September 30, 2023, June 30, 2023, and December 31, 2022, deposits priced utilizing these strategies totaled $1,232.4 million, $1,070.7 million and $579.1 million, respectively, and carried weighted average rates of 3.53%, 3.38%, and 1.64%, respectively.

(1)Certain information included herein is presented on a fully tax-equivalent (FTE) basis and / or to present additional financial details which may be desired by users of this financial information. 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 September 30, 2023, June 30, 2023, and September 30, 2022, purchased loan discount accretion was $1.3 million, $1.5 million, and $0.7 million, respectively.

Net interest income (FTE) during the three months ended September 30, 2023, decreased $0.5 million or 0.5% to $88.5 million compared to $89.0 million during the three months ended June 30, 2023. In addition, net interest margin declined 8 basis points to 3.88%, compared to the trailing quarter. The decrease in net interest income is primarily attributed to an additional $5.9 million or 24.3% in deposit interest expense 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 $5.2 million or 4.6%.

As compared to the same quarter in the prior year, average loan yields, excluding PPP, increased 65 basis points from 4.87% during the three months ended September 30, 2022, to 5.52% during the three months ended September 30, 2023. The accretion of discounts from acquired loans added 8 and 5 basis points to loan yields during the quarters ended September 30, 2023 and September 30, 2022, respectively.

The rates paid on interest bearing deposits increased by 41 basis points during the quarter ended September 30, 2023, compared to the trailing quarter. The cost of interest-bearing deposits increased by 128 basis points between the quarter ended September 30, 2023, and the same quarter of the prior year. In addition, the average balance of noninterest-bearing deposits decreased by $162.6 million quarter over quarter and decreased by $678.5 million from three month average for the period ended September 30, 2022. As of September 30, 2023, the ratio of average total noninterest-bearing deposits to total average deposits was 36.9%, as compared to 39.2% and 41.6% at June 30, 2023 and September 30, 2022, respectively.

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 September 30, 2023, the Company's loan portfolio consisted of approximately $6.7 billion in outstanding principal with a weighted average coupon rate of 5.33%. During the three-month periods ending September 30, 2023, June 30, 2023, and December 31, 2022, the weighted average coupon on loan production in the quarter was 7.31%, 6.85%, and 6.05%, respectively. Included in the September 30, 2023 loan total are adjustable rate loans totaling $3.5 billion, of which, $933.0 million are considered floating based on the Wall Street Prime index. In addition, the Company holds certain investment securities with fair values totaling $368.9 million which are subject to repricing on not less than a quarterly basis.

During the three months ended September 30, 2023, the Company recorded a provision for credit losses of $4.2 million, as compared to $9.7 million during the trailing quarter, and $3.8 million during the third quarter of 2022.

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

The following table presents the activity in the allowance for credit losses on loans for the periods indicated:

The allowance for credit losses (ACL) was $115.8 million or 1.73% of total loans as of September 30, 2023. The provision for credit losses on loans of $3.1 million during the recent quarter was the net effect of charge-offs associated with the disposition of a previously reserved for and individually analyzed relationship of credits, partially offset by increases in reserves for qualitative factors and quantitative reserves under the cohort model from loan growth. On a comparative basis, the provision for credit losses of $3.5 million during the three months ended September 30, 2022, was largely the result of loan growth. For the current quarter, the qualitative components of the ACL resulted in a net increase in required reserves totaling approximately $2.5 million due primarily to softening of the California employment data. Meanwhile, the quantitative component of the ACL decreased reserve requirements by approximately $1.5 million over the trailing quarter primarily due to decreases in specific reserves, offset partially by increases attributed to loan growth.

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, energy 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 decreased by $1.4 million during the quarter ended September 30, 2023, to $8.1 million, as compared to $9.5 million at June 30, 2023. Non-performing loans were $29.8 million at September 30, 2023, a decrease of $7.8 million from $37.6 million as of June 30, 2023, and an increase of $12.3 million from $17.5 million as of September 30, 2022. Of the $29.8 million loans designated as non-performing as of September 30, 2023, approximately $26.6 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:

The ratio of classified loans of 1.22% as of September 30, 2023 increased 22 basis points from June 30, 2023 and increased 36 basis points from the comparative quarter ended 2022. The newly classified credits are spread amongst several CRE and agriculture relationships. As a percentage of total loans outstanding, classified assets are 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 Company's combined criticized loan balances improved during the quarter by $44.6 million to $176.2 million as of September 30, 2023. This improvement was driven by upgrades in several CRE borrower relationships, as well as the disposition of a credit relationship referenced above.

There was one property added and one disposed within Other Real Estate Owned during the third quarter of 2023. As of September 30, 2023, other real estate owned consisted of nine properties with a carrying value of approximately $2.9 million.

Non-performing assets of $32.7 million at September 30, 2023, represented 0.33% of total assets, a change from the $40.5 million or 0.41% and $20.9 million or 0.21% as of June 30, 2023 and September 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 September 30, 2023, the unamortized discount associated with acquired loans totaled $26.1 million.

The following table presents the key components of non-interest income for the current and trailing quarterly periods indicated:

Non-interest income increased $0.2 million or 1.5% to $16.0 million during the three months ended September 30, 2023, compared to $15.7 million during the quarter ended June 30, 2023. Service charges on deposit accounts increased by $0.3 million or 5.9% resulting from improved profitability on commercial deposit account activity.

The following table presents the key components of non-interest income for the current and prior year periods indicated:

Non-interest income decreased $0.3 million or 2.2% to $16.0 million during the three months ended September 30, 2023, compared to $15.6 million during the quarter ended September 30, 2022. Service charges on deposit accounts increased by $0.4 million or 9.4% for the same reasons noted above.

Non-interest income decreased $1.8 million or 3.8% to $45.4 million during the nine months ended September 30, 2023, as compared to $47.2 million during the nine months ended September 30, 2022. Mortgage origination related activity has declined year over year from elevated interest rates, as the income recorded from the sale of loans is down $1.3 million or 58.8%. Changes in interest rates also led to a decline in fair value of mortgage servicing rights during the nine months ended September 30, 2023 , which decreased by $0.7 million or 148.5%, as compared to the trailing nine month period ended. Other income declined $0.9 million or 61.4%, $0.3 million of which is attributed to fair value changes associated with retirement plans, with a corresponding offset being included within benefits and other compensation costs.

The following table presents the key components of non-interest expense for the current and trailing quarterly periods indicated:

Non-interest expense for the quarter ended September 30, 2023, decreased $3.4 million or 5.5% to $57.9 million as compared to $61.2 million during the trailing quarter ended June 30, 2023. Data processing and software expenses increased by $0.6 million or 13.1% related to ongoing investments in the Company's data management and security infrastructure. Regulatory assessments decreased by $0.8 million or 40.1% to a normalized quarterly assessment following additional charges incurred in the prior quarter. Management anticipates that these costs may increase further if the economic environment in which the Company operates deteriorates further. Operational losses also decreased by $0.6 million or 56.5% during the quarter, in-line with historical periods. Other miscellaneous expenses decreased by $1.2 million or 23.0%, following non-recurring costs in the prior quarter associated with an estimated $0.8 million in refunds to customers previously charged non-sufficient funds fees as well as an absence in the current period of provision expense on real estate owned of $0.5 million in the trailing quarter.

The following table presents the key components of non-interest expense for the current and prior year quarterly periods indicated:

Non-interest expense increased $3.4 million or 6.3% to $57.9 million during the three months ended September 30, 2023, as compared to $54.5 million for the quarter ended September 30, 2022. Total salaries and benefits expense increased by $0.9 million or 2.8% to $34.5 million, largely from a net increase of 17 full-time equivalent positions as well as annual merit increases effective in March, 2023. Data processing and software expenses increased by $1.8 million or 52.1% consist with the discussion above. The increase in professional fees of $0.6 million was directly associated with third party contract negotiation assistance, the benefits of which will be realized in future periods.

Total non-interest expense increased $15.7 million or 10.0% to $172.9 million during the nine months ended September 30, 2023, as compared to $157.2 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 this acquisition totaled $6.2 million for the nine-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 miscellaneous expenses are consistent with the discussions provided above for the most recent three months ended September 30, 2023 as compared with the trailing quarter ended June 30, 2023.

The Company’s effective tax rate was 27.3% for the quarter ended September 30, 2023, as compared to 25.6% for the period ended June 30, 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.
