We had a return on average assets of 1.25% and a return on tangible common equity of 13.8%. These returns increased our tangible book value per share by 10% on an annualized basis this quarter. Over the past 10 years, we have produced a compounded annual growth rate of 10% on our tangible book value per share.

Highlights

•Earnings - Net income in the second quarter 2024 was $45.4 million, an increase of $5.0 million and a decrease of $3.7 million compared to the linked and prior year quarters, respectively. Earnings per share ("EPS") was $1.19 per diluted common share for the second quarter 2024, compared to $1.05 and $1.29 per diluted common share for the linked and prior year quarters, respectively. Adjusted diluted earnings per share1 was $1.21 for the second quarter 2024, compared to $1.07 for the linked quarter.

•Pre-provision net revenue ("PPNR")1 - PPNR of $63.3 million in the second quarter 2024 increased $5.9 million and decreased $5.7 million from the linked and prior year quarters, respectively. The increase from the linked quarter was primarily due to higher noninterest income, primarily tax credit income, and higher net interest income that benefited from higher average loan balances and expanding yields on earning assets. These increases were partially offset by an increase in deposit interest expense. The decrease compared to the prior year quarter was primarily due to the higher interest rate environment that increased

deposit interest expense and the cost of variable deposit services costs, which are influenced by current market rates.

•Net interest income and net interest margin ("NIM") - Net interest income of $140.5 million for the second quarter 2024 increased $2.8 million and decreased $0.2 million from the linked and prior year quarters, respectively. Compared to the linked quarter, net interest income for the second quarter 2024 increased due to an expanded net interest spread and higher average loan and interest-earning asset balances. NIM was 4.19% for the second quarter 2024, compared to 4.13% and 4.49% for the linked and prior year quarters, respectively. The total cost of deposits of 2.16% for the second quarter 2024 increased 3 basis points and 70 basis points from the linked and prior year quarters, respectively.

•Noninterest income - Noninterest income of $15.5 million for the second quarter 2024 increased $3.3 million and $1.2 million from the linked and prior year quarters, respectively. The increase from the linked and prior year quarters was primarily due to an increase in tax credit income on higher activity that was partially offset by an increase in market interest rates that decreased the fair value of certain tax credits.

•Noninterest expense - Noninterest expense of $94.0 million for the second quarter 2024 increased $0.5 million and $8.1 million from the linked and prior year quarters, respectively. The increase from the linked quarter was primarily driven by higher variable deposit servicing costs and expenses related to the core system conversion, partially offset by a decrease in employee compensation and the FDIC special assessment. The increase from the prior year quarter was primarily due to variable deposit servicing costs and employee compensation.

•Loans - Loans totaled $11.0 billion at June 30, 2024, a decrease of $28.5 million from the linked quarter and an increase of $487.4 million from the prior year quarter.

1 Average balances include nonaccrual loans. Interest income includes loan fees of $2.2 million, $2.4 million, and $3.7 million for the three months ended June 30, 2024, March 31, 2024, and June 30, 2023, respectively.
2 Non-taxable income is presented on a fully tax-equivalent basis using a tax rate of approximately 25%. The tax-equivalent adjustments were $2.1 million, $2.0 million, and $2.1 million for the three months ended June 30, 2024, March 31, 2024, and June 30, 2023, respectively.

Net interest income of $140.5 million for the second quarter 2024 increased $2.8 million and decreased $0.2 million from the linked and prior year quarters, respectively. Net interest income on a tax equivalent basis was $142.6 million, $139.8 million and $142.8 million for the current, linked and prior year quarters, respectively. The increase from the linked quarter was primarily due to an expansion of the loan portfolio and securities yields, and to a lesser extent, an increase in average earning assets. This was partially offset by an increase in both the cost and average balance of interest-bearing deposits. The decrease from the prior year quarter reflects higher interest expense on the deposit portfolio and continued remixing into higher cost deposit categories.

Interest income increased $3.9 million during the second quarter 2024. Interest on loans benefited from a $34.6 million increase in average loan balances compared to the linked quarter, as well as an 8 basis point increase in yield. The average interest rate of new loan originations in the second quarter 2024 was 8.07%, an increase of 23 basis points from the linked quarter. Interest on cash accounts increased $0.8 million from the linked quarter due to a $57.4 million increase in average balances, and interest on securities increased $0.5 million due to an 8 basis point increase in yield.

Interest expense increased $1.1 million in the second quarter 2024 primarily due to an increase in interest expense on certificates of deposit that includes brokered amounts. Average certificates of deposit increased $70.3 million and the cost increased 10 basis points in the second quarter 2024. The average cost of interest-bearing deposits was 3.19%, an increase of 5 basis points compared to the linked quarter. The total cost of deposits, including noninterest-bearing demand accounts, was 2.16% during the second quarter 2024, compared to 2.13% in the linked quarter. While the total cost of deposits increased over the linked quarter, the monthly cost of total deposits has been stable since March 2024.

NIM, on a tax equivalent basis, was 4.19% in the second quarter 2024, an increase of 6 basis points from the linked quarter and a decrease of 30 basis points from the prior year quarter. For the month of June 2024, the loan portfolio yield was 6.92% and the cost of total deposits was 2.17%.

*Guaranteed balances excluded	$	12,933	$	9,630	$	10,682	$	5,974	$	6,666

Nonperforming assets increased$4.0 million during the second quarter 2024 and increased $32.0 million from the prior year quarter. The increase in nonperforming assets in the current quarter was primarily related to the addition of an agricultural relationship that moved into nonperforming status during the period, partially offset by a reduction from charge-offs and repayments. Included in nonperforming loans is $1.3 million of loans that are 90 days past due and accruing interest. The Company anticipates full repayment of these loans. The increase in nonperforming assets

from the prior year quarter was primarily due to a $27.1 million increase in real estate loans and an $8.7 million increase in OREO and other repossessed assets, partially offset by a $2.9 million decrease in C&I loans. Annualized net charge-offs totaled 2 basis points of average loans in the second quarter 2024, compared to 22 basis points in the linked quarter and 12 basis point in the prior year quarter.

The provision for credit losses totaled $4.8 million in the second quarter 2024, compared to $5.8 million and $6.3 million in the linked and prior year quarters, respectively. The provision for credit losses in the second quarter 2024 was primarily related to an increase in reserves on individually evaluated loans and updates to qualitative factors used in the allowance calculation.

Total noninterest income was $15.5 million for the second quarter 2024, an increase of $3.3 million from the linked quarter and an increase of $1.2 million from the prior year quarter. The increase from the linked and prior year quarters was primarily due to an increase in tax credit income. Tax credit income is typically highest in the fourth quarter of each year and will vary in other periods based on transaction volumes and fair value changes on credits carried at fair value.

The decrease in other income from the linked quarter was primarily driven by gains on the sale of SBA loans that were recognized in the linked quarter, while the decrease from the prior year quarter was due to lower community development income. Community development income and private equity fund distributions are not consistent sources of income and fluctuate based on distributions from the underlying funds.

Noninterest Expense

The following table presents a comparative summary of the major components of noninterest expense for the periods indicated:

Linked quarter comparison	Prior year comparison
Quarter ended	Quarter ended
($ in thousands)	June 30, 2024	March 31, 2024	Increase (decrease)	June 30, 2023	Increase (decrease)
Employee compensation and benefits	$	44,524	$	45,262	$	(738)	(2)	%	$	41,641	$	2,883	7	%

Occupancy	4,197	4,326	(129)	(3)	%	3,954	243	6	%
FDIC special assessment	-	625	(625)	(100)	%	-	-	-	%
Core conversion expense	1,250	350	900	257	%	-	1,250	100	%
Other expense	22,340	22,661	(321)	(1)	%	23,381	(1,041)	(4)	%
Total noninterest expense	$	94,017	$	93,501	$	516	1	%	$	85,956	$	8,061	9	%

Employee compensation and benefits decreased $0.7 million from the linked quarter primarily due to employer payroll taxes that are seasonally higher in the first quarter each year and a decline in self-insured medical claims. Deposit costs relate to certain specialized deposit businesses that receive an earnings credit allowance for deposit related expenses that are impacted by interest rates and average balances. Deposit costs increased $1.4 million from the linked quarter primarily due to the expiration of unused allowances that reduced expense in the first quarter and growth in deposits. Expenses related to the core system conversion increased $0.9 million from the linked quarter due to the continued progress on the project.

The increase in noninterest expense of $8.1 million from the prior year quarter was primarily due to an increase in the associate base, merit increases throughout 2023 and 2024, an increase in variable deposit costs due to higher earnings credit rates and average balances, and additional expenses incurred related to the core system conversion.

For the second quarter 2024, the core efficiency ratio5 was 58.1%, compared to 60.2% for the linked quarter and 54.0% for the prior year quarter.

Income Taxes

The effective tax rate was 20.5%, compared to 20.2% and 21.6% in the linked and prior year quarters, respectively. The decrease in the effective tax rate from the prior year quarter was driven by tax credit opportunities the Company has deployed as part of its tax planning strategy.

Capital

*Capital ratios for the current quarter are preliminary and subject to, among other things, completion and filing of the Company's regulatory reports and ongoing regulatory review.

Total equity was $1.8 billion at June 30, 2024, an increase of $23.5 million from the linked quarter. Tangible common book value per share was $35.02 at June 30, 2024, compared to $34.21 and $31.23 at March 31, 2024 and June 30, 2023, respectively.

The Company's regulatory capital ratios continue to exceed the "well-capitalized" regulatory benchmark. Capital ratios for the current quarter are subject to, among other things, completion and filing of the Company's regulatory reports and ongoing regulatory review.

Use of Non-GAAP Financial Measures

The Company's accounting and reporting policies conform to generally accepted accounting principles in the United States ("GAAP") and the prevailing practices in the banking industry. However, the Company provides additional financial measures, such as tangible common equity, PPNR, ROATCE, core efficiency ratio, the tangible common equity ratio, tangible book value per common share, estimated insured deposits and adjusted diluted earnings per share, in this release that are considered "non-GAAP financial measures." Generally, a non-GAAP financial measure is a numerical measure of a company's financial performance, financial position, or cash flows that exclude (or include) amounts that are included in (or excluded from) the most directly comparable measure calculated and presented in accordance with GAAP.

The Company considers its tangible common equity, PPNR, ROATCE, core efficiency ratio, the tangible common equity ratio, tangible book value per common share, estimated insured deposits and adjusted diluted earnings per share, collectively "core performance measures," presented in this earnings release and the included tables as important measures of financial performance, even though they are non-GAAP measures, as they provide

5Core efficiency ratio is a non-GAAP measure. Refer to discussion and reconciliation of this measure in the accompanying financial tables.

supplemental information by which to evaluate the impact of certain non-comparable items, and the Company's operating performance on an ongoing basis. Core performance measures exclude certain other income and expense items, such as the FDIC special assessment, core conversion expenses, merger-related expenses, facilities charges, and the gain or loss on sale of investment securities, that the Company believes to be not indicative of or useful to measure the Company's operating performance on an ongoing basis. The attached tables contain a reconciliation of these core performance measures to the GAAP measures. The Company believes that the tangible common equity ratio provides useful information to investors about the Company's capital strength even though it is considered to be a non-GAAP financial measure and is not part of the regulatory capital requirements to which the Company is subject.

The Company believes these non-GAAP measures and ratios, when taken together with the corresponding GAAP measures and ratios, provide meaningful supplemental information regarding the Company's performance and capital strength. The Company's management uses, and believes that investors benefit from referring to, these non-GAAP measures and ratios in assessing the Company's operating results and related trends and when forecasting future periods. However, these non-GAAP measures and ratios should be considered in addition to, and not as a substitute for or preferable to, ratios prepared in accordance with GAAP. In the attached tables, the Company has provided a reconciliation of, where applicable, the most comparable GAAP financial measures and ratios to the non-GAAP financial measures and ratios, or a reconciliation of the non-GAAP calculation of the financial measures for the periods indicated.

While there is no assurance that any list of risks and uncertainties or risk factors is complete, important factors that could cause actual results to differ materially from those in the forward-looking statements include the following, without limitation: the Company's ability to efficiently integrate acquisitions into its operations, retain the customers of these businesses and grow the acquired operations, as well as credit risk, changes in the appraised valuation of real estate securing impaired loans, outcomes of litigation and other contingencies, exposure to general and local economic and market conditions, high unemployment rates, higher inflation and its impacts (including U.S. federal government measures to address higher inflation), U.S. fiscal debt, budget and tax matters, and any slowdown in global economic growth, risks associated with rapid increases or decreases in prevailing interest rates, our ability to attract and retain deposits and access to other sources of liquidity, consolidation in the banking industry, competition from banks and other financial institutions, the Company's ability to attract and retain relationship officers and other key personnel, burdens imposed by federal and state regulation, changes in legislative or regulatory requirements, as well as current, pending or future legislation or regulation that could have a negative effect on our revenue and businesses, including rules and regulations relating to bank products and financial services, changes in accounting policies and practices or accounting standards, changes in the method of determining LIBOR and the phase out of LIBOR, natural disasters, terrorist activities, war and geopolitical matters (including the war in Israel and potential for a broader regional conflict and the war in Ukraine and the imposition of additional sanctions and export controls in connection therewith), or pandemics, and their effects on economic and business environments in which we operate, including the related disruption to the financial market and other economic activity, and those factors and risks referenced from time to time in the Company's filings with the Securities and Exchange Commission (the "SEC"), including in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2023, and the Company's other filings with the SEC. The Company cautions that the preceding list is not exhaustive of all possible risk factors and other factors could also adversely affect the Company's results.
