Olympia, WA - Heritage Financial Corporation (Nasdaq GS: HFWA) (the “Company", ”we," or "us"), the parent company of Heritage Bank (the "Bank"), today reported net income of $12.2 million for the second quarter of 2025, compared to $13.9 million for the first quarter of 2025 and $14.2 million for the second quarter of 2024. Diluted earnings per share for the second quarter of 2025 were $0.36 compared to $0.40 for the first quarter of 2025 and $0.41 for the second quarter of 2024.
In the second quarter of 2025, the Company incurred a pre-tax loss of $6.9 million on the sale of investment securities in connection with the strategic repositioning of its balance sheet, which decreased diluted earnings per share by $0.15 for the quarter. The Company sold $91.6 million of investment securities with an average book yield of 2.63%. Net proceeds from the sale were used to purchase $56.4 million in investment securities with an average book yield of 5.06% and fund new loans originated during the quarter. The Company also incurred pre-tax losses on the sale of investment securities in connection with balance sheet repositioning during the first quarter of 2025 and second quarter of 2024 in the amounts of $3.9 million and $1.9 million, respectively, which decreased diluted earnings per share by $0.09 and $0.04, respectively, for such quarters.
In addition, the Company surrendered $8.5 million of its bank owned life insurance ("BOLI") portfolio during the second quarter of 2025, incurring tax expense related to the surrender of BOLI of $515,000 which decreased diluted earnings per share by $0.02 for the quarter.
Bryan McDonald, Chief Executive Officer of the Company, commented, "We are pleased with the continued growth in core earnings, both compared to the prior quarter and to the same quarter in the prior year. This is partly due to the ongoing expansion of our net interest margin, due mostly to increases in yields on loans and investment securities. Despite a seasonal decline in deposit balances in the second quarter, our total deposits have increased $100 million since year-end 2024. We continue to strategically reposition our balance sheet to improve future profitability and will consider investment in new production teams when favorable opportunities are presented. Although these actions may impact current earnings, we believe future earnings will be enhanced and we are optimistic that the combination of our strong balance sheet and prudent risk management will provide sustainable long-term returns for our shareholders."

Non-maturity deposits decreased by $57.3 million, or 1.2%, from March 31, 2025 due primarily to a decline in customer balances in noninterest bearing demand and interest bearing demand accounts.

Although total deposits at June 30, 2025 decreased from March 31, 2025, average total deposits increased $35.4 million during the second quarter of 2025.

Total borrowings decreased $1.2 million to $263.2 million at June 30, 2025 from $264.4 million at March 31, 2025. All outstanding borrowings at June 30, 2025 were with the Federal Home Loan Bank ("FHLB") and mature within one year.
Total stockholders' equity increased $6.7 million, or 0.8%, to $888.2 million at June 30, 2025 compared to $881.5 million at March 31, 2025 due primarily to $12.2 million of net income recognized for the quarter. The increase in total stockholders' equity was also due to a $6.2 million decrease in accumulated other comprehensive loss as a result of losses recognized on sales of investment securities in connection with balance sheet repositioning efforts. These increases were partially offset by $8.3 million in dividends paid to common shareholders and $4.6 million of stock repurchases.
The Company and Bank continued to maintain capital levels in excess of the applicable regulatory requirements for them both to be categorized as “well-capitalized” at June 30, 2025.
The following table summarizes the capital ratios for the Company at the dates indicated:

Allowance for Credit Losses and Provision for Credit Losses
The allowance for credit losses ("ACL") on loans as a percentage of loans receivable was 1.10% at June 30, 2025 compared to 1.09% at March 31, 2025. The increase in the ACL as a percentage of loans was due primarily to changes in the weighted average life of the loans in the real estate construction and land development segment. During the second quarter of 2025, the Company recorded an $863,000 provision for credit losses on loans, compared to a $9,000 reversal of provision for credit losses on loans during the first quarter of 2025. The provision for credit losses on loans recognized during the second quarter of 2025 was due primarily to charge-offs of $494,000 and secondarily to growth in balances of collectively evaluated loans.
During the second quarter of 2025, the Company recorded a $93,000 provision for credit losses on unfunded commitments compared to a $60,000 provision during the first quarter of 2025. The provision for credit losses on unfunded commitments during the second quarter of 2025 was due primarily to an increase in the unfunded exposure on construction loans.

The Company downgraded $38.2 million of loans to substandard during the second quarter of 2025, including, non-owner occupied CRE loans of $16.3 million, commercial and industrial loans of $9.7 million, commercial and multifamily construction loans of $6.0 million, and owner occupied CRE loans of $5.7 million.

Nonaccrual loans increased by $5.4 million during the second quarter of 2025 due primarily to the migration of a $6.0 million commercial and multifamily construction loan and a $1.7 million commercial and industrial loan.

Net Interest Margin and Net Interest Income
The net interest margin increased seven basis points to 3.51% during the second quarter of 2025 from 3.44% during the first quarter of 2025.
The yield on interest earning assets increased six basis points to 5.01% for the second quarter of 2025, compared to 4.95% for the first quarter of 2025. The yield on loans receivable increased five basis points to 5.50% during the second quarter of 2025, compared to 5.45% during the first quarter of 2025 as new loans were booked and adjustable rate loans repriced at higher rates.
The cost of interest bearing deposits increased two basis points to 1.94% for the second quarter of 2025 from 1.92% for the first quarter of 2025. This increase was primarily due to an increase in rates on interest bearing demand and money market accounts during the quarter, offset partially by a decrease in certificate of deposit rates.
Net interest income increased $1.3 million, or 2.4%, during the second quarter of 2025 compared to the first quarter of 2025 due to a $1.1 million increase in total interest income and a decrease in interest expense of $0.2 million.
The net interest margin increased 24 basis points to 3.51% from 3.27% compared to the same period in the prior year. Net interest income increased $3.9 million, or 7.6%, during the second quarter of 2025 compared to the second quarter of 2024. The increase was due to a change in the mix of earning assets to higher yielding loan balances and a decrease in borrowing interest expense due to lower average balances, partially offset by an increase in deposit interest expense resulting from increased average balances and rates.
The following table provides relevant net interest income information for the periods indicated:

Noninterest Income
Noninterest income decreased $2.4 million to $1.5 million during the second quarter of 2025 from $3.9 million during the first quarter of 2025. The decrease was due primarily to higher losses resulting from the above-referenced sale of investment securities recognized in the second quarter of 2025 as part of the strategic repositioning of the balance sheet, compared to losses recognized in the prior quarter. The decrease was partially offset by an increase in BOLI income due to death benefit proceeds and an increase in card revenue due to increased card activity.
Noninterest income decreased $3.7 million from the same period in 2024 due primarily to higher losses resulting from the above-referenced sale of investment securities recognized in the second quarter of 2025 as part of the strategic repositioning of the balance sheet, compared to losses recognized in the same quarter in 2024. The decrease was partially offset by an increase in BOLI income as a result of BOLI restructuring which occurred in the fourth quarter of 2024 and an increase in other income primarily due to an increase in FHLB dividend income.
