During the quarter ended March 31, 2025, the Company sold $91.9 million of one-to-four-family loans compared to $138.9 million during the previous quarter and $93.9 million during the same quarter one year ago. The decrease in the volume of loans sold during the current quarter compared to the prior quarter was primarily due to seasonal factors combined with economic volatility. Gross margins on home loan sales increased to 3.26% for the quarter ended March 31, 2025, compared to 3.14% in the previous quarter and decreased from 3.43% in the same quarter one year ago. Gross margins are defined as the margin on loans sold (cash sales) without the impact of deferred costs.

Page 8

At March 31, 2025, CDs, which include retail and non-retail CDs, totaled $1.23 billion, compared to $1.03 billion at December 31, 2024 and $1.11 billion at March 31, 2024, with non-retail CDs representing 28.5%, 15.0% and 31.0% of total CDs at such dates, respectively. At March 31, 2025, non-retail CDs, which include brokered CDs, online CDs and public funds CDs, increased $196.9 million to $351.7 million, compared to $154.8 million at December 31, 2024, primarily due to an increase of $196.8 million in brokered CDs.  The increase in brokered CDs provided funds to pay down higher cost borrowings. Non-retail CDs totaled $351.7 million at March 31, 2025, compared to $344.5 million at March 31, 2024.

At March 31, 2025, the Bank had uninsured deposits of approximately $679.4 million, compared to approximately $652.7 million at December 31, 2024, and $614.1 million at March 31, 2024.  The uninsured amounts are estimates based on the methodologies and assumptions used for the Bank's regulatory reporting requirements.

At March 31, 2025, borrowings decreased $239.0 million to $68.8 million at March 31, 2025, from $307.8 million at December 31, 2024, and decreased $61.1 million from $129.9 million at March 31, 2024. These borrowings were comprised solely of FHLB advances.

Total stockholders’ equity increased $3.1 million to $298.8 million at March 31, 2025, from $295.8 million at December 31, 2024, and increased $20.9 million, from $277.9 million at March 31, 2024. The increase in stockholders’ equity at March 31, 2025, compared to December 31, 2024, was primarily due to net income of $8.0 million and $513,000 in equity award compensation, partially offset by share repurchases of $3.8 million and cash dividends paid of $2.2 million. Stockholders’ equity was also impacted by decreases in unrealized net losses on securities available for sale of $2.7 million, net of tax, and decreases in unrealized net gains on fair value and cash flow hedges of $2.6 million, net of tax, reflecting changes in market interest rates during the quarter, resulting in a $151,000 decrease in accumulated other comprehensive loss, net of tax. Book value per common share was $39.12 at March 31, 2025, compared to $38.26 at December 31, 2024, and $36.06 at March 31, 2024.

The Bank is considered “well capitalized” under the capital requirements established by the Federal Deposit Insurance Corporation (“FDIC”) with a total risk-based capital ratio of 14.4%, a Tier 1 leverage capital ratio of 11.3%, and a common equity Tier 1 (“CET1”) capital ratio of 13.2% at March 31, 2025.

The Company exceeded all regulatory capital requirements with a total risk-based capital ratio of 14.7%, a Tier 1 leverage capital ratio of 9.9%, and a CET1 ratio of 11.5% at March 31, 2025.

Credit Quality

The allowance for credit losses on loans (“ACLL”) was $31.7 million, or 1.25% of gross loans receivable (excluding loans HFS) at March 31, 2025, compared to $31.9 million, or 1.26% of gross loans receivable (excluding loans HFS), at December 31, 2024, and $31.5 million, or 1.29% of gross loans receivable (excluding loans HFS), at March 31, 2024. The slight decrease in the ACLL at March 31, 2025, compared to the prior quarter was primarily due to a decrease in the balance of higher risk consumer loans.  The increase of $174,000 in the ACLL from the same quarter the prior year was primarily due to increases in CRE loans. The allowance for credit losses on unfunded loan commitments increased $66,000 to $1.5 million at March 31, 2025, compared to $1.4 million at December 31, 2024, and decreased $35,000 from $1.5 million at March 31, 2024, primarily due to an increase in the volume of unfunded commitments on construction loans

Nonperforming loans increased $870,000 to $14.5 million at March 31, 2025, compared to $13.6 million at December 31, 2024, and increased $2.4 million from $12.1 million at March 31, 2024. The increase in nonperforming loans compared to the prior quarter was primarily due to increases in nonperforming CRE construction and development loans of $1.5 million, nonperforming indirect home improvement loans of $1.1 million, and nonperforming one-to-four-family loans of $970,000, partially offset by decreases in nonperforming CRE loans of $1.6 million and nonperforming commercial business loans of $1.5 million. The increase in nonperforming loans compared to the same quarter the prior year was primarily due to increases in nonperforming construction and development loans of $1.8 million, nonperforming one-to-four-family loans of $961,000, and nonperforming indirect home improvement loans of $626,000, partially offset by a decrease in nonperforming commercial business loans of $1.4 million.

Loans classified as substandard increased $602,000 to $23.5 million at March 31, 2025, compared to $22.9 million at December 31, 2024, and decreased $1.4 million from $24.9 million at March 31, 2024.  The increase in substandard loans compared to the prior quarter was primarily due to an increase of $1.5 million in CRE construction and development loans, $1.1 million in indirect home improvement loans, and $953,000 in one-to-four-family loans, partially offset by decreases in commercial business loans of $1.8 million and CRE of $1.6 million.  The decrease in substandard loans compared to the prior year was primarily due to decreases of $3.1 million in C&I loans and $1.9 million in CRE loans, partially offset by increases of $1.8 million in CRE construction and development loans, $794,000 in one-to-four-family loans, and $626,000 in indirect home improvement loans. 

Operating Results

Net interest income increased $636,000 to $31.0 million for the three months ended March 31, 2025, from $30.3 million for the three months ended March 31, 2024, primarily due to an increase in total interest income of $1.9 million, partially offset by an increase in interest expense of $1.3 million. The $1.9 million increase in total interest income was primarily due to an increase of $2.3 million in interest income on loans receivable, including fees, primarily as a result of net loan growth and variable rate loans repricing higher. The $1.3 million increase in total interest expense was primarily the result of higher market interest rates and a net increase in interest bearing liabilities.

NIM (annualized) increased six basis points to 4.32% for the three months ended March 31, 2025, from 4.26% for the same period in the prior year. The increase in NIM for the three months ended March 31, 2025, compared to the same period in 2024, reflects the increased yields on interest-earning assets. 

The average total cost of funds, including noninterest-bearing checking, increased 17 basis points to 2.38% for the three months ended March 31, 2025, from 2.21% for the three months ended March 31, 2024. This increase was predominantly due to higher market rates for borrowings. 

For the three months ended March 31, 2025, the provision for credit losses on loans was $1.5 million, compared to $1.4 million for the three months ended March 31, 2024. The provision for credit losses on loans reflects an increase in charge-off activity. During the three months ended March 31, 2025, net charge-offs increased $247,000 to $1.7 million, compared to $1.5 million for the same period last year.  This increase was the result of increased net charge-offs of $487,000 in indirect home improvement loans and $25,000 in commercial business loans, partially offset by a net reduction of net charge-offs of $213,000 in marine loans and $46,000 in other consumer loans. Management attributes the increase in net charge-offs over the year primarily to volatile economic conditions.

Total noninterest income was unchanged at $5.1 million for the three months ended March 31, 2025 and 2024.   Total noninterest expense was $25.0 million for the three months ended March 31, 2025, compared to $23.5 million for the three months ended March 31, 2024.  The $1.5 million increase was primarily due to a $976,000 increase in salaries and benefits and a $437,000 increase in operations expense.

Non-GAAP Financial Measures:

In addition to financial results presented in accordance with generally accepted accounting principles utilized in the United States (“GAAP”), this earnings release presents non-GAAP financial measures that include tangible book value per share, and tangible common equity ratio. Management believes that providing the Company’s tangible book value per share and tangible common equity ratio is consistent with the capital treatment utilized by the investment community, which excludes intangible assets from the calculation of risk-based capital ratios and facilitates comparison of the quality and composition of the Company's capital over time and to its competitors. Where applicable, the Company has also presented comparable GAAP information.

These non-GAAP financial measures have inherent limitations, are not required to be uniformly applied, and are not audited. They should not be considered in isolation or as a substitute for total stockholders' equity or operating results determined in accordance with GAAP. These non-GAAP measures may not be comparable to similarly titled measures reported by other companies.

Reconciliation of the GAAP book value per share and common equity ratio and the non-GAAP tangible book value per share and tangible common equity ratio is presented below.
