Net Interest Income and Net Interest Margin

Net interest income before provision for credit losses was $27.6 million for the third quarter of 2023, compared to $31.9 million for the second quarter of 2023. The $4.3 million decrease was primarily attributable to an increase in interest expense on time deposits and a decrease in interest and fees on loans, partially offset by increases in interest income on interest-bearing deposits and on investment securities. For the third quarter of 2023, average time deposits increased $70.8 million and the interest rate paid on time deposits increased 35 basis points to 4.33% from 3.98% in the second quarter of 2023.

Compared to the third quarter of 2022, net interest income before provision for credit losses decreased $11.4 million from $39.0 million. The decrease was primarily attributable to an increase in average interest-bearing deposits of $651.7 million and a 301 basis point increase in the interest rate paid on interest-bearing deposits, partially offset by an increase in average loans of $31.5 million and a 46 basis point increase in the yield earned on loans from 5.53% in the third quarter of 2022 to 5.99%.

Net interest margin was 2.87% for the third quarter of 2023, a decrease of 50 basis points from 3.37% in the second quarter of 2023 primarily due to a 36 basis point increase in the average cost of interest-bearing deposits from 3.47% in the second quarter of 2023 to 3.83% in the third quarter of 2023. Cost of interest-bearing deposits increased due to increasing market rates and peer bank deposit competition.

The Company will redeem on December 1, 2023 the 2028 Subordinated Notes at a redemption price equal to 100% of the principal amount of the 2028 Subordinated Notes plus accrued and unpaid interest to but excluding December 1, 2023. The 2028 Subordinated Notes have an aggregate principal amount outstanding of $55 million. From and after December 1, 2023, all interest on the 2028 Subordinated Notes will cease to accrue.

Noninterest Income

Noninterest income was $7.7 million for the third quarter of 2023, an increase of $5.2 million from $2.5 million in the second quarter of 2023. The increase was primarily driven by a $5.0 million CDFI ERP award received, a $194,000 increase in gain on sale of loans, and a $190,000 increase in gain on sale of other real estate owned (“OREO”), partially offset by a $110,000 decrease in wealth management commissions during the quarter.

2

Noninterest Expense

Noninterest expense for the third quarter of 2023 was $16.9 million, compared to $18.5 million for the second quarter of 2023. The $1.6 million decrease was primarily attributable to a $1.9 million decrease in legal and other professional fees, partially offset by a $417,000 increase in salaries and employee benefits expenses primarily due to new hires in the quarter. The decrease in legal and other professional fees were primarily due to the insurance coverage with respect to legal expenses related to the Company's voluntary cooperation with the Securities and Exchange Commission's (“SEC”) requests for information, as disclosed in the Company's Current Report on Form 8-K filed with the SEC on July 24, 2023, after all prior payments of the Company reached the $1.0 million retention amount.

Income Taxes

The effective tax rate was 29.8% for the third quarter of 2023, 29.5% for the second quarter of 2023, and 27.8% for the third quarter of 2022.

Loan and Securities Portfolio

Loans held for investment, net of deferred fees and discounts, totaled $3.1 billion as of September 30, 2023, a decrease of $75.0 million from June 30, 2023, and a decrease of $100.0 million from September 30, 2022. The decrease from June 30, 2023 was primarily due to a $49.4 million decrease in single-family residential mortgages, a $19.2 million decrease in commercial real estate loans, a $3.8 million decrease in commercial and industrial loans, a $3.0 million decrease in Small Business Administration (“SBA”) loans, and a $2.5 million decrease in other loans, partially offset by a $2.9 million increase in construction and land development loans. The decrease from September 30, 2022 was primarily due to a $93.7 million decrease in construction and land development loans, a $77.2 million decrease in commercial and industrial loans, a $56.6 million decrease in commercial real estate loans, an $11.5 million decrease in SBA loans, and a $10.0 million decrease in other loans, partially offset by a $149.0 million increase in single-family residential mortgages. In the first nine months of 2023, management decreased loan growth to lower the loan to deposit ratio and to strengthen the liquidity position of the Company.

As of September 30, 2023, the Bank’s total available-for-sale securities amounted to $354.4 million, including available-for-sale securities maturing in over 12 months of $259.4 million. As of September 30, 2023, the Bank recorded gross unrealized losses of $37.1 million on its available-for-sale securities compared to gross unrealized losses of $32.3 million as of June 30, 2023 with respect to its available-for-sale securities due to Federal Reserve Bank raised interest rate by 25 basis points in July 2023.

Liquidity and Deposits

Total deposits were $3.2 billion as of September 30, 2023, which reflected a decrease of $21.3 million or 0.7% compared to June 30, 2023, primarily due to a decrease in brokered deposits of $49.1 million, partially offset by an increase in time deposits of $31.7 million. As of September 30, 2023, the Company had $330.8 million in cash on the balance sheet, which is an increase of $84.5 million or 34.3% from June 30, 2023. In addition, the Company had $909.8 million in Federal Home Loan Bank borrowing availability, Fed fund lines of $92.0 million, $41.9 million in available funds from the Federal Reserve Bank's discount window and $261.2 million in available-for-sale securities that were unpledged.

Credit Quality

Nonperforming assets totaled $40.4 million, or 0.99% of total assets at September 30, 2023, compared to $42.2 million, or 1.04% of total assets at June 30, 2023. The $1.8 million decrease in nonperforming assets was due to loans that migrated to accrual status of $2.2 million, loans charged-off of $2.2 million, loan paydowns of $295,000, and one OREO of $293,000 that was sold, partially offset by loans that migrated into non-accrual status of $3.2 million, consisting primarily of commercial real estate loans and single-family residential mortgages.

Special mention loans totaled $31.2 million or 1.00% of total loans at September 30, 2023, compared to $24.2 million, or 0.76% of total loans at June 30, 2023. The increase is due to additional special mention loans of $9.3 million, consisting primarily of commercial real estate loans, partially offset by an upgrade to pass loans of $2.2 million.

Substandard loans totaled $71.4 million or 2.29% of total loans at September 30, 2023, compared to $74.1 million, or 2.32% of total loans at June 30, 2023. The decrease is due to loan paydowns of $3.2 million and upgrades to pass loans of $823,000, partially offset by additional substandard loans of $1.4 million, consisting primarily of single-family residential mortgages.

30-89 day delinquent loans, excluding non-accrual loans, increased $12.4 million to $19.7 million as of September 30, 2023 compared to $7.2 million as of June 30, 2023. The $12.4 million increase in past due loans was primarily due to a new delinquent commercial real estate loan of $16.1 million for one business day payment delay, which reverted back to current in October 2023. Offsetting the increase were loans that migrated back to past due for less than 30 days in the amount of $4.8 million, consisting primarily of single-family residential mortgages, loans that converted to non-accrual status in the aggregate amount of $835,000, and loan payoffs or paydowns of $575,000.

3

Total net charge-offs were $2.2 million for the third quarter of 2023, as compared to net charge-offs of $580,000 in the prior quarter and net recoveries of $127,000 in the same quarter last year.

Provision for credit losses were $1.4 million for the third quarter of 2023, as compared to $380,000 in the prior quarter and $1.8 million in the same quarter last year.

The allowance for credit losses totaled $42.4 million, or 1.36% of loans held for investment at September 30, 2023, compared with $43.1 million, or 1.35%, of loans held for investment at June 30, 2023.

Dividend Payout and Stock Repurchase

For the third quarter of 2023, the Board of Directors declared a common stock cash dividend of $0.16 per share, payable on November 10, 2023 to stockholders of record on October 30, 2023.

On June 14, 2022, the Board of Directors authorized the repurchase of up to 500,000 shares of common stock, of which 433,124 shares remain available. The repurchase program permits shares to be repurchased in open market or private transactions, through block trades, and pursuant to any trading plan that may be adopted in accordance with SEC Rules 10b5-1 and 10b-8. The Company did not repurchase any shares during the third quarter of 2023, and has not repurchased any shares since October 24, 2022 pursuant to this authorization.

Return on Average Tangible Common Equity

Management measures return on average tangible common equity (“ROATCE”) to assess the Company’s capital strength and business performance and believes these are helpful to investors as an additional tool for further understanding our performance. Tangible equity excludes goodwill and other intangible assets (excluding mortgage servicing rights), and is reviewed by banking and financial institution regulators when assessing a financial institution’s capital adequacy. This non-GAAP financial measure should not be considered a substitute for operating results determined in accordance with GAAP and may not be comparable to other similarly titled measures used by other companies. The following table reconciles ROATCE to its most comparable GAAP measure:
