Operating Results

Net Income and Earnings Per Common Share

Net income totaled $16.4 million for the first quarter of 2026, compared to $17.9 million for the fourth quarter of 2025 and $13.6 million for the first quarter of 2025. Net income available to common shareholders totaled $15.2 million for the first quarter of 2026, compared to $16.7 million for the fourth quarter of 2025 and $12.4 million for the first quarter of 2025. The quarter-over-quarter decrease from the fourth quarter of 2025 was primarily due to merger-related expenses attributing to an increase in legal and professional expenses, and an increase in salaries and employee benefits related to sign-on bonuses, retention and additional bonuses. Dividends on our Series A Convertible Non-Cumulative Preferred Stock ("Series A Preferred Stock") totaled $1.2 million for each of the quarters ended March 31, 2026, December 31, 2025 and March 31, 2025.

Basic and diluted earnings per common share were $1.03 per share and $0.88 per share, respectively, in the first quarter of 2026, compared to $1.21 per share and $1.02 per share, respectively, in the fourth quarter of 2025 and $0.90 per share and $0.78 per share, respectively, in the first quarter of 2025.

Net Interest Margin and Net Interest Income

The net interest margin for the first quarter of 2026 was 3.67%, compared to 4.10% for the fourth quarter of 2025 and 3.80% for the first quarter of 2025. The yield on loans for the first quarter of 2026 was 7.01%, compared to 7.52% for the fourth quarter of 2025 and 7.45% for the first quarter of 2025. The cost of interest-bearing deposits for the first quarter of 2026 was 3.53%, compared to 3.73% for the fourth quarter of 2025 and 4.02% for the first quarter of 2025.

Net interest income totaled $53.6 million for the first quarter of 2026, an increase of 2.8% from $52.2 million for the fourth quarter of 2025 and an increase of 25.3% from $42.8 million for the first quarter of 2025. Interest income totaled $97.4 million for the first quarter of 2026, an increase of 5.7% from $92.1 million for the fourth quarter of 2025 and an increase of 20.6% from $80.8 million for the first quarter of 2025. The quarter-over-quarter increase from the fourth quarter of 2025 in interest income primarily resulted from an increase in loans, slightly offset by a $1.0 million reversal of interest income on a loan placed on nonaccrual and a decrease in loan yields. Interest expense was $43.7 million for the first quarter of 2026, an increase of $3.8 million, or 9.6%, from $39.9 million for the fourth quarter of 2025 and an increase of $5.8 million, or 15.2%, from $38.0 million for the first quarter of 2025, primarily resulting from an increase in interest-bearing demand deposits slightly offset by a reduction in rates paid on interest-bearing demand deposits.

Noninterest Income and Noninterest Expense

Noninterest income totaled $4.0 million for the first quarter of 2026, compared to $4.3 million for the fourth quarter of 2025 and $3.1 million for the first quarter of 2025. The quarter-over-quarter decrease from the fourth quarter of 2025 in noninterest income was primarily due to a decrease in non-margin loan fees during the first quarter of 2026.

Noninterest expense increased to $38.1 million for the first quarter of 2026, compared to $32.7 million for the fourth quarter of 2025 and $28.1 million for the first quarter of 2025. The quarter-over-quarter increase from the fourth quarter of 2025 in noninterest expense was primarily due to merger-related expenses. During the first quarter of 2026, the Company recorded $3.3 million in Keystone merger-related noninterest expenses primarily attributable to $1.6 million in legal and professional expenses and $1.3 million in salaries and employee benefits. Additionally, the Company recorded $644,000 in salaries and employee benefits attributable to sign-on bonuses and additional discretionary bonuses during the first quarter of 2026. At March 31, 2026, the number of employees increased to 514, compared to 412 at December 31, 2025 primarily due to the Keystone merger.

The efficiency ratio was 66.06% for the first quarter of 2026, compared to 57.90% for the fourth quarter of 2025 and 61.23% for the first quarter of 2025.

Balance Sheet Highlights

Loan Portfolio and Composition

For the quarter ended March 31, 2026, gross loans increased to $5.25 billion, an increase of $856.7 million, or 19.5%, from $4.39 billion as of December 31, 2025, and an increase of $1.26 billion, or 31.7%, from $3.99 billion as of March 31, 2025. The increase in gross loans was impacted by the mid-quarter Keystone merger. Commercial and industrial loans and real estate loans accounted for the majority of the loan growth for the first quarter of 2026, with commercial and industrial loans increasing $276.2 million and real estate loans increasing $644.2 million from the fourth quarter of 2025, partially offset by municipal and other loans decreasing $64.4 million from the fourth quarter of 2025.

Asset Quality

Nonperforming loans at March 31, 2026 were $35.6 million, compared to $21.5 million at December 31, 2025 and $18.6 million at March 31, 2025. The increase in nonperforming loans during the first quarter of 2026 was primarily due to one loan for approximately $17.1 million that was placed on nonaccrual partially offset by a $5.0 million decline in loans over 90 days past due and still accruing. As of March 31, 2026, the nonperforming loans to total loans ratio was 0.68%, compared to 0.49% as of December 31, 2025 and 0.47% as of March 31, 2025.

The provision for credit loss recorded for the first quarter of 2026 was $580,000, and the allowance for credit losses of $51.5 million represented 0.98% of the $5.25 billion in gross loans outstanding as of March 31, 2026. The provision for credit loss recorded for the fourth quarter of 2025 was $2.2 million, and the allowance for credit losses of $43.9 million represented 1.00% of the $4.39 billion in gross loans outstanding as of December 31, 2025. The increase in the allowance for credit loss in the first quarter of 2026 compared to the fourth quarter of 2025 was primarily attributable to Day 1 allowance for credit losses related to the Keystone merger.

The Company recorded net recoveries of $4,000 and net charge-offs of $398,000 for the three months ended March 31, 2026 and March 31, 2025, respectively.

Deposits and Composition

Deposits totaled $5.72 billion as of March 31, 2026, an increase of 23.5% from $4.63 billion as of December 31, 2025, and an increase of 34.5% from $4.25 billion as of March 31, 2025. The increase in total deposits was impacted by the mid-quarter Keystone merger. Noninterest-bearing demand deposits increased from $495.0 million as of December 31, 2025, to $577.2 million as of March 31, 2026 and represented 10.1% and 10.7% of total deposits as of March 31, 2026 and December 31, 2025, respectively. As of March 31, 2026, interest-bearing demand deposits increased $912.1 million, or 27.1%, time deposits increased $90.0 million, or 12.0%, and savings accounts increased $3.8 million, or 17.6%, respectively, from December 31, 2025.

The average cost of deposits was 3.17% for the first quarter of 2026, representing a 17-basis point decrease from the fourth quarter of 2025 and a 44-basis point decrease from the first quarter of 2025. The decreases were primarily due to the reduction in rates paid on interest-bearing demand deposits.

GAAP Reconciliation and Management's Explanation of Non-GAAP Financial Measures

(unaudited)

Our accounting and reporting policies conform to GAAP (generally accepted accounting principles) and the prevailing practices in the banking industry. However, we also evaluate our performance based on certain additional financial measures discussed in this earnings release as being non-GAAP financial measures. Specifically, we review Tangible Common Equity, Tangible Book Value Per Common Share, Tangible Common Equity to Tangible Assets, and Return on Average Tangible Common Equity for internal planning and forecasting purposes. We classify a financial measure as a non-GAAP financial measure if that financial measure excludes or includes amounts, or is subject to adjustments that have the effect of excluding or including amounts, that are not included or excluded, as the case may be, in the most directly comparable measure calculated and presented in accordance with GAAP as in effect from time to time in the United States in our statements of income, balance sheets or statements of cash flows. Non-GAAP financial measures do not include operating and other statistical measures or ratios, or statistical measures calculated using exclusively financial measures calculated in accordance with GAAP.

The non-GAAP financial measures that we discuss in this earnings release should not be considered in isolation or as a substitute for the most directly comparable or other financial measures calculated in accordance with GAAP. Moreover, the manner in which we calculate the non-GAAP financial measures that we discuss in this earnings release may differ from that of other companies reporting measures with similar names. It is important to understand how other banking organizations calculate their financial measures with names similar to the non-GAAP financial measures we have discussed in this earnings release when comparing such non-GAAP financial measures.

Management believes the following non-GAAP financial measures assist investors in understanding the financial condition of the company:

Tangible Common Equity. The most directly comparable GAAP financial measure for tangible common equity is total shareholders' equity. We believe that this measure is important to many investors in the marketplace who are interested in the relative changes from period to period of tangible common equity.
Tangible Book Value Per Common Share. The most directly comparable GAAP financial measure for tangible book value per common share is book value per common share. We believe that the tangible book value per common share measure is important to many investors in the marketplace who are interested in changes from period to period in book value per common share exclusive of changes in intangible assets. Goodwill and other intangible assets have the effect of increasing total book value while not increasing our tangible book value.
Tangible Common Equity to Tangible Assets. The most directly comparable GAAP financial measure for tangible common equity is total shareholders' equity, the most directly comparable GAAP financial measure for tangible assets is total assets, and the most directly comparable GAAP financial measure for tangible common equity to tangible assets is total shareholders' equity to total assets. We believe that this measure is important to many investors in the marketplace who are interested in the relative changes from period to period of tangible common equity to tangible assets, each exclusive of changes in intangible assets. Goodwill and other intangible assets have the effect of increasing both total shareholders' equity and assets while not increasing our tangible common equity or tangible assets.
Return on Average Tangible Common Equity. The most directly comparable GAAP financial measure for average tangible common equity is average shareholders' equity, and the most directly comparable GAAP financial measure for return on average tangible common equity is return on average common equity. We believe that this measure is important to many investors in the marketplace who are interested in the relative changes from period to period of return on average tangible common equity, exclusive of changes in intangible assets. Goodwill and other intangible assets have the effect of increasing average shareholders' equity while not increasing our tangible common equity.

The calculations of these non-GAAP financial measures are as follows:
