Board Declares Cash Dividend of $0.14 per Share

On July 21, 2026, the Company's Board of Directors declared a cash dividend of $0.14 per share, which represents a 16.7% increase from the previous quarterly dividend of $0.12 per share. The dividend will be paid on August 18, 2026, to stockholders of record of the Company's common stock as of August 4, 2026.

STATEMENTS OF OPERATIONS HIGHLIGHTS

Net Interest Income

Net interest income for the second quarter of 2026 was $100.8 million, an increase of $973,000, or 1.0%, from the first quarter of 2026. The increase in net interest income was primarily due to one additional calendar day, partially offset by higher interest expense related to increased funding costs.

Tax-equivalent net interest margin (1) for the second quarter of 2026 was 4.29%, a decrease of five basis points compared to the first quarter of 2026. The decrease primarily reflected modest compression in earning asset yields and higher funding costs. Net loan accretion income contributed 11 basis points to the net interest margin for the quarter.

The average cost of total deposits was 1.92% for the second quarter of 2026, a modest increase of one basis point compared to the first quarter of 2026.

Provision for Credit Losses

The provision for credit losses was $7.2 million for the second quarter of 2026, an increase of $1.6 million, or 29.3%, compared to $5.5 million for the first quarter of 2026, mainly due to additional allocation on individually assessed loans and growth in the loan and lease portfolio.

Non-interest Income

Non-interest income for the second quarter of 2026 was $16.9 million, an increase of $4.3 million, or 34.6%, compared to $12.5 million for the first quarter of 2026. The increase in total non-interest income was principally driven by four factors: a $1.9 million favorable change in the fair value of equity securities, a $736,000 improvement in the fair value adjustment on loan servicing assets, $627,000 in higher net gains on sales of loans, and higher other non-interest income, primarily reflecting gains on sales of leased assets and swap fee income.

Net gains on sales of loans totaled $6.1 million for the quarter, an increase of $627,000, or 11.5%, compared to the prior quarter. During the second quarter of 2026, we sold $78.1 million of U.S. government guaranteed loans compared to $71.8 million during the first quarter of 2026.

Non-interest Expense

Non-interest expense for the second quarter of 2026 was $56.5 million, a decrease of $710,000, or 1.2%, compared to $57.2 million for the first quarter of 2026. The decrease in non-interest expense was primarily driven by a $673,000 decline in net losses recognized on other real estate owned, a $589,000 decrease in salaries and employee benefits expense, and a $380,000 decrease in occupancy and equipment expense, partially offset by a $496,000 impairment charge related to a closed branch held for sale and higher other non-interest expense.

Our efficiency ratio was 46.93% (1), and our adjusted efficiency ratio was 46.51% (1), each compared to 49.78% (1) for the first quarter of 2026, an improvement of 285 basis points and 327 basis points, respectively. The improvement in the efficiency ratio was driven by increased revenue and lower non-interest expense.

Income Taxes

We recorded income tax expense of $13.9 million during the second quarter of 2026, compared to $12.1 million during the first quarter of 2026. The effective tax rates were 25.7% and 24.4% for the second quarter of 2026 and first quarter of 2026, respectively. This increase was primarily driven by income tax benefits related to share-based compensation recorded in the prior quarter.

STATEMENTS OF FINANCIAL CONDITION HIGHLIGHTS

Assets

Total assets were $9.9 billion as of June 30, 2026, an increase of $22.8 million, or 0.2%, compared to $9.9 billion at March 31, 2026. The increase was primarily driven by a $67.1 million increase to loans and leases held for investment, largely in originated commercial and industrial loans, partially offset by a decrease in securities available-for-sale of $39.4 million, mainly due to principal paydowns.

Allowance for Credit Losses

The ACL was $111.9 million as of June 30, 2026, an increase of $3.0 million, or 2.7%, from March 31, 2026, mainly due to an increased provision for credit losses on individually assessed loans and lower net charge-offs on loans and leases.

Net loan and lease charge-offs during the second quarter of 2026 were $4.4 million, or 0.24% of average loans and leases on an annualized basis, a decrease of $1.5 million and eight basis points, compared to the first quarter of 2026. The decrease was primarily driven by higher recoveries compared to the prior quarter and lower charge-offs on government guaranteed loans.

Asset Quality

Non-performing assets were $72.2 million, or 0.73% of total assets, as of June 30, 2026, an increase of $2.1 million from March 31, 2026. The increase was primarily due to increased non-accrual loans and leases. The government guaranteed portion of non-performing loans included in non-performing assets was $8.1 million at June 30, 2026, compared to $7.7 million at March 31, 2026, an increase of $399,000.

Deposits and Other Liabilities

Total deposits increased $68.9 million, or 0.9% to $7.9 billion at June 30, 2026 from $7.8 billion as of March 31, 2026. The increase was primarily driven by growth in interest-bearing deposits.

Total borrowings and other liabilities were $757.5 million at June 30, 2026, a decrease of $70.1 million from $827.6 million at March 31, 2026. The decrease for the quarter was primarily driven by lower FHLB advances.

Stockholders’ Equity

Total stockholders’ equity was $1.3 billion at June 30, 2026, an increase of $23.9 million, or 1.9%, from March 31, 2026, primarily due to net income of $40.2 million, partially offset by share repurchases, dividends declared, and an increase in accumulated other comprehensive loss related to available-for-sale securities. During the quarter ended June 30, 2026, we repurchased 274,528 shares of our common stock.

RECONCILIATION OF NON-GAAP FINANCIAL MEASURES (unaudited)

Non-GAAP Financial Measures

This release contains certain financial information determined by methods other than in accordance with accounting principles generally accepted in the United States of America (“GAAP”). These measures include adjusted net income, adjusted diluted earnings per share, adjusted non-interest expense, adjusted non-interest expense excluding amortization of intangible assets, adjusted efficiency ratio, adjusted non-interest expense to average assets, tax equivalent net interest income, tax-equivalent net interest margin, total revenue, non-interest income to total revenues, adjusted return on average stockholders’ equity, adjusted return on average assets, pre-tax pre-provision net income, adjusted pre-tax pre-provision net income, pre-tax pre-provision return on average assets, adjusted pre-tax pre-provision return on average assets, tangible common stockholders' equity, tangible assets, average tangible assets, tangible net income, adjusted tangible net income, tangible book value per common share, tangible common equity to tangible assets, return on average tangible common stockholders' equity, and adjusted return on average tangible common stockholders' equity. Management believes that these non-GAAP financial measures provide useful information to management and investors that is supplementary to the Company’s financial condition, results of operations and cash flows computed in accordance with GAAP; however, management acknowledges that our non-GAAP financial measures have a number of limitations. As such, these disclosures should not be viewed as a substitute for results determined in accordance with GAAP financial measures that we and other companies use. Management also uses these measures for peer comparison. See below in the financial schedules included in this press release for a reconciliation of the non-GAAP financial measures to the comparable GAAP financial measures. Additionally, please refer to the Company’s Annual Report on Form 10-K for the detailed definitions of these non-GAAP financial measures.
