Total stockholders' equity decreased $25.9 million, or 2.3%, to $1.08 billion at September 30, 2026, compared to $1.11 billion at June 30, 2026.

During the third quarter of 2026, the Company recorded a $2.3 million provision for credit losses on loans, compared to an $844,000 reversal of provision during the second quarter of 2026. The provision for credit losses on loans was due primarily to loan growth during the quarter.

Net Interest Income and Net Interest Margin

Net interest income increased $2.4 million, or 3.3%, during the third quarter of 2026 compared to the second quarter of 2026 due to a $2.5 million increase in total interest income, offset partially by an increase in interest expense of $74,000. The increase in net interest income was primarily due to an increase in the net interest margin.

Net interest margin increased six basis points to 4.05% during the third quarter of 2026, from 3.99% during the second quarter of 2026. The increase in net interest margin was due primarily to the increase in yield on loans and a decrease in the cost of interest bearing deposits.

The yield on interest earning assets increased five basis points to 5.26% for the third quarter of 2026, compared to 5.21% for the second quarter of 2026. The increase was primarily due to an increase in yield on loans.

The yield on loans receivable increased four basis points to 5.76% during the third quarter of 2026, compared to 5.72% during the second quarter of 2026. The increase was due primarily to an increase in rates on loans originated during the third quarter of 2026. Loan yield also benefited from the incremental accretion on purchased loans in both the second and third quarters of 2026.

The following table presents the net interest margin and loan yield and the effect of the incremental accretion on purchased loans on these ratios for the periods indicated:

	Quarter Ended
	September 30, 2026		June 30, 2026		September 30, 2025

(1)	Represents a non-GAAP financial measure. See "Non-GAAP Financial Measures" section for a reconciliation to the comparable GAAP financial measure.
(2)	Represents the amount of interest income recorded on purchased loans in excess of the contractual stated interest rate in the individual loan notes due to incremental accretion of purchased discount or premium. Purchased discount or premium is the difference between the contractual loan balance and the fair value of acquired loans at the acquisition date. The purchased discount is accreted into income over the remaining life of the loan. The impact of incremental accretion on loan yield will change during any period based on the volume of prepayments, but it is expected to decrease over time as the balance of the purchased loans decreases.

The cost of interest bearing deposits decreased two basis points to 1.65% for the third quarter of 2026, from 1.67% for the second quarter of 2026. This decrease was primarily due to a decrease in rates on certificates of deposit.

Net interest margin increased 41 basis points to 4.05% during the third quarter of 2026, compared to 3.64% for the same period in the prior year. Net interest income increased $19.9 million, or 34.7%, during the third quarter of 2026 compared to the same period in the prior year, due to a combination of an increase in average interest earning assets, which increased substantially as a result of the Merger, and an increase in net interest margin.

Noninterest Income

Noninterest income decreased $58,000 to $9.3 million during the third quarter of 2026. The decrease was due primarily to a decrease in bank owned life insurance ("BOLI") income.

Noninterest income increased $928,000 during the third quarter of 2026 from the same period in 2025 due primarily to increases in service charges and other fees, card revenue, and BOLI income due to income from the deposit portfolio and BOLI acquired from Olympic.

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

Noninterest Expense

Noninterest expense decreased $2.4 million, or 3.7%, to $62.0 million during the third quarter of 2026, compared to $64.3 million in the second quarter of 2026. The decrease was primarily due to a decrease in Merger-related expenses.

Merger-related expenses consisted of severance expense, professional fees, core conversion costs, exit costs related to the consolidation of two branches, closure of one loan production office and one administration location, and contract termination costs. Merger-related expenses incurred in the third quarter of 2026 were $5.2 million compared to $7.5 million in the second quarter of 2026.

The following table presents Merger-related expenses included in noninterest expense and the change for the periods indicated:

Noninterest expense increased $20.3 million, or 48.9%, during the third quarter of 2026 compared to the same period in 2025 due primarily to an increase in expenses related to the Merger and the addition of Olympic's operations.

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

Income Tax Expense

Income tax expense increased $385,000 in the third quarter of 2026, compared to the second quarter of 2026 due to higher pre-tax income during the third quarter of 2026.

Income tax expense increased $426,000 in the third quarter of 2026, compared to the same period in 2025, due primarily to an increase in the effective income tax rate during the third quarter of 2026.

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

Stock Repurchase Program

On October 21, 2026, the Company's Board of Directors approved a new stock repurchase program, authorizing the repurchase of up to 5% of the Company's outstanding common shares or approximately 2.0 million shares. The number, timing and price of shares repurchased will depend on business and market conditions, and other factors, including opportunities to deploy the Company's capital.

The new stock repurchase program supersedes a prior stock repurchase program, which was authorized in April 2024 and allowed for the buyback of approximately 1.7 million shares.
