CEO COMMENTARY

Charles (Chip) Reeves, Chief Executive Officer of the Company, commented, “Despite the difficult interest rate environment, which continues to compress our net interest margin, we had another strong quarter of strategic plan execution, highlighted by the September announcement of the sale of our Florida operations, with the proceeds reinvested into the acquisition of Denver Bankshares. These two transactions align our geographic footprint with our Strategic Plan, while accelerating our Denver market growth by three to four years. We are confident in our ability to integrate this low-risk merger, while continuing our growth trajectory in the attractive Denver MSA. Also, in the third quarter of 2023, our Treasury Management initiatives and client acquisition strategies resulted in balanced loan and deposit growth, providing ample flexibility for future, selective loan growth. Asset quality metrics were affected by one senior living credit moving to non-accrual, however, charge-offs and 30-89 day past dues remain at historically low levels. We remain diligent as uncertain economic conditions begin to normalize asset quality migration.”

Mr. Reeves continued, “While we continue to invest for growth, we are also laser focused on improving our operational effectiveness. Expenses in the quarter were well-controlled and our cost savings initiative to reduce noninterest expense by 2.5% is well underway. To conclude, we've made substantial progress executing our strategic initiatives over the last two quarters, and while we have more to do, I could not be more pleased with our team and the execution of our strategic initiatives.”

Total revenue, net of interest expense	$	44,436	$	45,708	$	58,321	(3)	%	(24)	%

Total revenue for the third quarter of 2023 decreased $1.3 million from the second quarter of 2023 as a result of lower net interest income, partially offset by higher noninterest income. Compared to the third quarter of 2022, total revenue decreased $13.9 million due to lower net interest income and noninterest income.

Net interest income of $34.6 million for the third quarter of 2023 decreased $2.4 million from the second quarter of 2023 and $11.2 million from the third quarter of 2022 as a result of higher funding costs and volumes and lower interest earning asset volumes, partially offset by higher interest earning asset yields.

The Company's tax equivalent net interest margin was 2.35% in the third quarter of 2023 compared to 2.52% in the second quarter of 2023, as higher earning asset yields were more than offset by increased funding costs. The cost of interest bearing liabilities increased 35 basis points ("bps") to 2.33%, due to interest bearing deposit costs of 2.05%, short-term borrowing costs of 4.29%, and long-term debt costs of 6.78%, which increased 26 bps, 138 bps and 40 bps, respectively from the second quarter of 2023. Total interest earning assets yield increased 12 bps from the second quarter of 2023, as a result of an increase in loan and securities yields of 14 bps and 1 bp, respectively. Our cycle-to-date interest bearing deposit beta was 34%.

The tax equivalent net interest margin was 2.35% in the third quarter of 2023 compared to 3.08% in the third quarter of 2022, driven by higher funding costs and volumes, partially offset by higher interest earning asset yields. The cost of interest bearing liabilities increased 169 bps to 2.33%, due to interest bearing deposit costs of 2.05%, short-term borrowing costs of 4.29%, and long-term debt costs of 6.78%, which increased 159 bps, 295 bps and 208 bps, respectively from the third quarter of 2022. Total interest earning assets yield increased 67 bps from the third quarter of 2022, primarily as a result of an increase in loan and securities yields of 75 bps and 9 bps, respectively.

Results are not meaningful (n/m)

Noninterest income for the third quarter of 2023 increased $1.1 million from the linked quarter due primarily to a $0.6 million favorable change in loan revenue, coupled with a $0.5 million increase in other revenue. Loan revenue reflected a favorable quarter-over quarter change in the fair value of our mortgage servicing rights of $0.9 million, partially offset by a decrease in loan sale gains generated by our governmental lending business and a decrease in revenue in our mortgage origination business. Other revenue reflected an increase of $0.6 million in swap origination fee income. Noninterest income decreased $2.7 million from the third quarter of 2022, primarily due to the decline of $2.9 million in other revenue stemming from a one-time settlement recognized in the third quarter of 2022.

Noninterest expense for the third quarter of 2023 decreased $3.4 million, or 9.7%, from the linked quarter with overall decreases in all noninterest expense categories except foreclosed assets, net. The decrease in compensation and employee benefits reflected a reduction of $1.1 million in severance expense, as well as a reduction of $1.1 million in medical insurance benefit expense, driven primarily by accrual adjustments. The $0.4 million decline in other noninterest expense was driven by various changes, including $0.2 million of executive relocation expense recognized in the linked quarter that did not recur and reduced loan expenses by $0.2 million. The $0.4 million decrease in marketing reflected a decline in advertising and sponsorships.

3

Noninterest expense for the third quarter of 2023 decreased $3.1 million, or 8.9%, from the third quarter of 2022, with overall decreases in all noninterest expense categories except FDIC insurance. These decreases primarily reflected a $1.8 million decline in employee benefits and incentives and commission expense, coupled with a $0.8 million decrease in merger-related expenses.

The Company's effective income tax rate increased to 19.4% in the third quarter of 2023 compared to 17.4% in the linked quarter. The higher effective income tax rate reflected an adjustment to the full-year 2023 estimated taxable income in the Company's annual effective tax rate calculation. The effective income tax rate for the full year 2023 is expected to be in the range of 18% - 20%.

BALANCE SHEET REVIEW

Total assets were $6.47 billion at September 30, 2023, compared to $6.52 billion at June 30, 2023 and $6.49 billion at September 30, 2022. The decrease from June 30, 2023 was driven by lower cash and securities balances, partially offset by higher loan balances. Compared to September 30, 2022, the decrease was due primarily to lower securities balances resulting from the balance sheet repositioning executed in the first quarter of 2023 as well as lower cash balances, partially offset by higher loan balances.

The increase when compared to the linked quarter was due to increased Federal Home Loan Bank overnight borrowings, partially offset by a reduction in securities sold under agreements to repurchase.

Total shareholders' equity at September 30, 2023 increased $4.1 million from June 30, 2023, driven by the benefit of third quarter net income, partially offset by an increase in accumulated other comprehensive loss and dividends paid during the third quarter of 2023.

(2) Classified loans ratio is calculated as classified loans divided by loans held for investment, net of unearned income, at the end of the period.
(3) Nonperforming loans ratio is calculated as nonperforming loans divided by loans held for investment, net of unearned income, at the end of the period.
(4) Nonperforming assets ratio is calculated as nonperforming assets divided by total assets at the end of the period.
(5) Allowance for credit losses ratio is calculated as allowance for credit losses divided by loans held for investment, net of unearned income, at the end of the period.

Compared to the linked quarter, nonperforming loans and assets ratios increased 35 bps and 23 bps, respectively, and when compared to the prior year increased 2 bps and 5 bps, respectively, to 0.71% and 0.45%, primarily due to the downgrade of a single commercial relationship.

As of September 30, 2023, the allowance for credit losses was $51.6 million, or 1.27% of loans held for investment, net of unearned income, compared with $50.4 million, or 1.25% of loans held for investment, net of unearned income, at June 30, 2023. Credit loss expense of $1.6 million in the third quarter of 2023 was primarily attributable to loan growth.

2 Forward Looking Statements & Non-GAAP Measures This presentation contains certain “forward-looking statements” within the meaning of such term in the Private Securities Litigation Reform Act of 1995. We and our representatives may, from time to time, make written or oral statements that are “forward-looking” and provide information other than historical information. These statements involve known and unknown risks, uncertainties and other factors that may cause actual results to be materially different from any results, levels of activity, performance or achievements expressed or implied by any forward-looking statement. These factors include, among other things, the factors listed below. Forward-looking statements, which may be based upon beliefs, expectations and assumptions of our management and on information currently available to management, are generally identifiable by the use of words such as “believe,” “expect,” “anticipate,” “should,” “could,” “would,” “plans,” “goals,” “intend,” “project,” “estimate,” “forecast,” “may” or similar expressions. These forward-looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially from those expressed in, or implied by, these statements. Readers are cautioned not to place undue reliance on any such forward-looking statements, which speak only as of the date made. Additionally, we undertake no obligation to update any statement in light of new information or future events, except as required under federal securities law. Our ability to predict results or the actual effect of future plans or strategies is inherently uncertain. Factors that could have an impact on our ability to achieve operating results, growth plan goals and future prospects include, but are not limited to, the following: (1) the risks of mergers or branch sales (including with Iowa First Bancshares Corp. and Denver Bankshares, Inc.), including, without limitation, the related time and costs of implementing such transactions, integrating operations as part of these transactions and possible failures to achieve expected gains, revenue growth and/or expense savings from such transactions; (2) credit quality deterioration, pronounced and sustained reduction in real estate market values, or other uncertainties, including the impact of inflationary pressures on economic conditions and our business, resulting in an increase in the allowance for credit losses, an increase in the credit loss expense, and a reduction in net earnings; (3) the effects of recent and potential additional increases in inflation and interest rates, including on our net income and the value of our securities portfolio; (4) changes in the economic environment, competition, or other factors that may affect our ability to acquire loans or influence the anticipated growth rate of loans and deposits and the quality of the loan portfolio and loan and deposit pricing; (5) fluctuations in the value of our investment securities; (6) governmental monetary and fiscal policies; (7) changes in and uncertainty related to benchmark interest rates used to price loans and deposits; (8) legislative and regulatory changes, including changes in banking, securities, trade, and tax laws and regulations and their application by our regulators, including the new 1.0% excise tax on stock buybacks by publicly traded companies and any changes in response to the recent failures of other banks; (9) the ability to attract and retain key executives and employees experienced in banking and financial services; (10) the sufficiency of the allowance for credit losses to absorb the amount of actual losses inherent in our existing loan portfolio; (11) our ability to adapt successfully to technological changes to compete effectively in the marketplace; (12) credit risks and risks from concentrations (by geographic area and by industry) within our loan portfolio; (13) the effects of competition from other commercial banks, thrifts, mortgage banking firms, consumer finance companies, credit unions, securities brokerage firms, insurance companies, money market and other mutual funds, financial technology companies, and other financial institutions operating in our markets or elsewhere or providing similar services; (14) the failure of assumptions underlying the establishment of allowances for credit losses and estimation of values of collateral and various financial assets and liabilities; (15) volatility of rate-sensitive deposits; (16) operational risks, including data processing system failures or fraud; (17) asset/liability matching risks and liquidity risks; (18) the costs, effects and outcomes of existing or future litigation; (19) changes in general economic, political, or industry conditions, nationally, internationally or in the communities in which we conduct business, including the risk of a recession; (20) changes in accounting policies and practices, as may be adopted by state and federal regulatory agencies and the Financial Accounting Standards Board; (21) war or terrorist activities, including the Israeli-Palestinian conflict and the Russian Invasion of Ukraine, widespread disease or pandemic, or other adverse external events, which may cause deterioration in the economy or cause instability in credit markets; (22) the occurrence of fraudulent activity, breaches, or failures of our information security controls or cyber-security related incidents, including as a result of sophisticated attacks using artificial intelligence and similar tools; (23) the imposition of tariffs or other domestic or international governmental policies impacting the value of the agricultural or other products of our borrowers; (24) effects of the ongoing COVID-19 pandemic, including its effects on the economic environment, our customers, employees and supply chain; (25) the concentration of large deposits from certain clients who have balances above current FDIC insurance limits; (26) the effects of recent developments and events in the financial services industry, including the large-scale deposit withdrawals over a short period of time at other banks that resulted in failure of those institutions; and (27) other risk factors detailed from time to time in Securities and Exchange Commission filings made by the Company. Non-GAAP Measures This presentation contains non-GAAP measures for tangible common equity, tangible book value per share, tangible common equity ratio, loan yield, tax equivalent, efficiency ratio, pre-tax, pre-provision earnings, return on average tangible equity, and net interest margin, tax equivalent. Management believes these measures provide investors with useful information regarding the Company’s profitability, financial condition and capital adequacy, consistent with how management evaluates the Company’s financial performance. A reconciliation of each non-GAAP measure to the most comparable GAAP measure is included, as necessary, in the Non-GAAP Financial Measures section.
