Total stockholders' equity increased $2.9 million, or 0.3%, to $850.5 million at June 30, 2024 compared to $847.6 million at March 31, 2024 due primarily to $14.2 million of net income recognized for the quarter, partially offset by $8.1 million in dividends paid to common shareholders and $4.4 million in common stock repurchases.

On April 24, 2024, the Company's Board of Directors authorized the repurchase of up to 5% of the Company's outstanding common stock or approximately 1.7 million shares. The new stock repurchase program superseded the previous stock repurchase program, which was authorized in March 2020 and allowed for the buyback of approximately 1.8 million shares. The previous program was substantially completed during the quarter ended March 31, 2024. During the second quarter of 2024, the Company repurchased 240,153 shares.

The Company and Bank continued to maintain capital levels in excess of the applicable regulatory requirements for them both to be categorized as “well-capitalized” at June 30, 2024.

Allowance for Credit Losses and Provision for Credit Losses

The allowance for credit losses ("ACL") on loans as a percentage of loans receivable was 1.13% at June 30, 2024 compared to 1.12% at March 31, 2024. During the second quarter of 2024, the Company recorded a $1.5 million provision for credit losses on loans, compared to a $1.7 million provision for credit losses on loans during the first quarter of 2024. The provision for credit losses on loans during the second quarter of 2024 was primarily driven by loan growth during the quarter.

During the second quarter of 2024, the Company recorded a $202,000 reversal of provision for credit losses on unfunded commitments compared to a $312,000 reversal of provision for credit losses on unfunded commitments during the first quarter of 2024. The reversal of provision for credit losses on unfunded commitments during the second quarter of 2024 was due primarily to a decrease in the unfunded exposure on loans and an increase in utilization rates.

Credit Quality

The percentage of classified loans to loans receivable increased to 1.8% at June 30, 2024, compared to 1.6% at March 31, 2024. Classified loans include loans rated substandard or worse. The increase was due primarily to the downgrade of a single $15.1 million commercial and multifamily construction loan to substandard from special mention. Total loans designated as special mention decreased by $8.5 million to $93.7 million at June 30, 2024, compared to $102.2 million at March 31, 2024.

Net Interest Income and Net Interest Margin

Net interest income decreased $417,000, or 0.8%, during the second quarter of 2024 compared to the first quarter of 2024 due primarily to an increase of $2.6 million in interest expense offset partially by a $2.2 million increase in interest income. Net interest margin decreased three basis points to 3.29% during the second quarter of 2024 from 3.32% during the first quarter of 2024.

The cost of interest bearing deposits increased 19 basis points to 1.89% for the second quarter of 2024 from 1.70% for the first quarter of 2024. This increase was primarily due to customers transferring balances from non-maturity deposits to higher rate certificates of deposit.

The yield on interest earning assets increased 14 basis points to 4.93% for the second quarter of 2024, compared to 4.79% for the first quarter of 2024. The yield on loans receivable, net, increased 11 basis points to 5.52% during the second quarter of 2024 compared to 5.41% during the first quarter of 2024 due primarily to higher rates on new and renewed loans. The impact to loan yield from recoveries of interest and fees on loans classified as nonaccrual was three basis points during the second quarter of 2024, compared to no impact during the first quarter of 2024. The yield on taxable securities increased nine basis points to 3.38% during the second quarter of 2024 compared to 3.29% during the first quarter of 2024 due primarily to sales of lower yielding investments during the first and second quarters of 2024.

Net interest income decreased $4.7 million, or 8.4%, during the second quarter of 2024 compared to the second quarter of 2023 and the net interest margin decreased 27 basis points to 3.29% from 3.56% during this same period. The decrease was due primarily to an increase in interest expense resulting from increased deposit rates and borrowing expense, partially offset by an increase in yields earned on interest earning assets following increases in market interest rates.

Noninterest Income

Noninterest income increased $8.1 million to $5.2 million during the second quarter of 2024 from a loss of $2.9 million during the first quarter of 2024. The increase was due primarily to the reduction of loss resulting from the sale of investment securities recognized in the second quarter of 2024 compared to the prior quarter.

Noninterest income decreased $2.0 million from the same period in 2023 due primarily to a $1.9 million pre-tax loss on the sale of investment securities during the second quarter of 2024. Card revenue declined modestly due to a reduction in card activity as non-maturity deposit balances have declined.

The following table presents the key components of noninterest income and the change for the periods indicated:

Noninterest Expense

Noninterest expense decreased $1.3 million, or 3.2%, during the second quarter of 2024 from the first quarter of 2024 due primarily to a decline in compensation and employee benefits. Compensation and employee benefits declined due primarily to severance costs resulting from staff reductions of $1.1 million recognized during the first quarter of 2024 offset partially by an increase in salary expense due to annual merit increases in base pay. Occupancy and equipment declined due primarily to a

7

decrease in maintenance costs related to winter weather conditions experienced in the first quarter of 2024. Data processing increased during the quarter due to a non-recurring $230,000 refund recognized in the first quarter of 2024 related to a contract termination.

Noninterest expense decreased $2.2 million, or 5.4%, during the second quarter of 2024 compared to the same period in 2023, primarily due to a decrease in data processing and other expense. Data processing decreased primarily due to a decline in ongoing costs resulting from prior technology-related contract renewals and terminations. Other expense decreased due to a decrease in customer account loss expense and a reduction in employee related expenses which included additional expenses in the second quarter of 2024 related to newly added teams. Compensation and employee benefits decreased due to a reduction in full-time equivalent employees to 748 at June 30, 2024 from 813 at June 30, 2023.

The following table presents the key components of noninterest expense and the change for the periods indicated:

Income Tax Expense

Income tax expense increased $716,000 during the second quarter of 2024 to $1.8 million compared to $1.1 million for the first quarter of 2024. The increase in income tax expense during the current quarter compared to the prior quarter was primarily due to an increase in pre-tax income during the second quarter of 2024. The effective tax rate declined during the second quarter of 2024 compared to the prior quarter due to recognition of a discrete tax expense item related to restricted stock awards in the first quarter of 2024 and a reduction in forecasted pre-tax income which caused a downward adjustment to the annualized effective tax rate.

Income tax expense decreased during the second quarter of 2024 compared to the second quarter of 2023 due to lower pre-tax income during the second quarter of 2024. The effective tax rate declined due to lower pre-tax income which increased the impact of favorable permanent tax items such as tax-exempt investments, investments in bank owned life insurance and tax credits.

The following table presents the income tax expense and related metrics and the change for the periods indicated:

	Quarter Ended									Change
	June 30, 2024			March 31, 2024			June 30, 2023			Quarter Over Quarter			Prior Year Quarter

NON-GAAP FINANCIAL MEASURES (Unaudited)

(Dollars in thousands, except per share amounts)

The Company considers the return on average tangible common equity ratio to be a useful measurement of the Company’s ability to generate returns for its common shareholders. By removing the impact of intangible assets and their related amortization and tax effects, the performance of the Company's ongoing business operations can be evaluated. The Company believes that presenting an adjusted return on tangible common equity ratio, which excludes certain non-recurring items is useful in measuring performance of the Company's ongoing business operations by removing the volatility of these non-recurring items.
