A summary of loans by major category as of March 31, 2026 and December 31, 2025 is as follows:

Total loans, net	$	127,647		$	128,635

First mortgage loans serviced and subserviced for others are not included in the accompanying Consolidated Balance Sheets. The unpaid principal balance of these loans totaled $39.5 million and $41.0 million at March 31, 2026 and December 31, 2025, respectively. Custodial escrow balances maintained in connection with the loans serviced were $396,000 and $480,000 at March 31, 2026 and December 31, 2025, respectively.

The accrued interest receivable for loans, net, was $586,000 and $577,000 for March 31, 2026 and December 31, 2025, respectively

In the normal course of business, loans are made by the Bank to directors and officers of the Company and the Bank (related parties). The terms of these loans, including interest rate and collateral, are similar to those prevailing for comparable transactions with other customers and do not involve more than a normal risk of collectability. At March 31, 2026 and December 31, 2025, such borrowers were indebted to the Bank in the aggregate amount of $547,000 and $564,000, respectively.

The following tables present the activity in the allowance for credit losses ("ACL") for the three months ended March 31, 2026 and 2025:

The ACL on loans excludes $46,000 and $67,000 of allowance for off-balance sheet exposures as of March 31, 2026 and 2025, respectively, recorded within Other Liabilities on the Consolidated Balance Sheets. Off-balance sheet exposures consist of unused lines of credit, the unused portion of construction loans and commitments to originate loans. The net release of provision for credit losses for the three months ended March 31, 2026 in the table above excludes a provision for credit losses of $7,000 related to off balance sheet exposures. The net release of provision for credit losses for the three months ended March 31, 2025 in the table above excludes a provision for credit losses of $8,000 related to off balance sheet exposures.

As of March 31, 2026, there were three collateral dependent loans totaling $1.7 million in the one to four-family residential loan segment. These loans are collateralized by residential real estate and have no ACL as of March 31, 2026. As of December 31, 2025, there were two collateral dependent loans totaling $284,000 in the one to four-family residential loan segment. These loans are collateralized by residential real estate and have no ACL as of December 31, 2025. There were no other collateral dependent loans as of March 31, 2026 and December 31, 2025.

The Bank evaluates collectability based on payment activity and other factors. The Bank uses a graded loan rating system as a means of identifying potential problem loans, as follows:

Pass

Loans in these categories are performing as expected with low to average risk.

Special Mention

Loans in this category are internally designated by management as “watch loans.” These loans are starting to show signs of potential weakness and are closely monitored by management.

Substandard

Loans in this category are internally designated by management as “substandard.” Generally, a loan is considered substandard if it is inadequately protected by the paying capacity of the obligors or the current net worth of the collateral pledged. Substandard loans present a distinct possibility that the Bank will sustain losses if such weaknesses are not corrected.

Doubtful

Loans classified as doubtful have all the weaknesses inherent in those designated as “substandard” with the added characteristic that the weaknesses may make collection or liquidation in full, on the basis of currently existing facts, highly questionable and improbable.

On an annual basis, or more often if needed, the Bank formally reviews the ratings on commercial loans. In addition, the Bank performs an independent review of a significant portion of the commercial loan portfolio. Management uses the results of the independent review as part of its annual review process.

The following tables present the credit risk profile of the Company's loan portfolio based on risk rating category and year of origination as of March 31, 2026 and December 31, 2025.

The Bank may modify loans to borrowers experiencing financial difficulty by providing modifications to repayment terms; more specifically, modifications to loan interest rates. Management performs an analysis at the time of loan modification. Any reserve required is recorded through a provision to the allowance for credit losses on loans. There were no modifications on loans to borrowers experiencing financial difficulty during the three months ended March 31, 2026 and 2025.
