Loans receivable increased $14.1 million, or 0.3%, during the fourth quarter of 2025 due to new loan production for the quarter offset partially by an elevated level of prepaid and closed loans. New loans funded during the fourth quarter of 2025 were $173.1 million, compared to $174.5 million during the third quarter of 2025. Loan prepayments increased to $77.2 million during the quarter, compared to $75.6 million during the prior quarter. Loan payoffs increased to $74.5 million, compared to $55.8 million in the prior quarter.

Commercial and industrial loans decreased $1.1 million, or 0.1%, during the fourth quarter of 2025, due primarily to pay downs on outstanding balances, partially offset by new loan production of $28.8 million. Owner-occupied commercial real estate ("CRE") loans increased $12.1 million, or 1.2%, during the fourth quarter of 2025, due primarily to new loan production of $40.0 million, partially offset by pay downs on outstanding balances. Non-owner occupied CRE loans increased $119.7 million, or 6.2%, during the quarter, due primarily to transfers from commercial and multifamily construction loans and new loan production of $76.5 million, partially offset by pay downs on outstanding balances. Residential real estate loans decreased by $16.0 million, or 4.3%, during the quarter, due to loan payoffs. Residential construction loans increased by $4.9 million, or 5.4%, during the quarter, due primarily to new loan production.

Total deposits increased $62.7 million, or 1.1%, to $5.92 billion at December 31, 2025 from $5.86 billion at September 30, 2025. Non-maturity deposits increased by $75.1 million, or 1.5%, from September 30, 2025, due primarily to an increase in customer balances in interest bearing demand accounts. The increase in non-maturity deposits was partially offset by a decrease of $12.4 million in certificates of deposit accounts.

Total borrowings decreased $118.0 million to $20.0 million at December 31, 2025, from $138.0 million at September 30, 2025. All outstanding borrowings at December 31, 2025 were with the Federal Home Loan Bank ("FHLB") and mature within one year.

Total stockholders' equity increased $17.4 million, or 1.9%, to $921.5 million at December 31, 2025, compared to $904.1 million at September 30, 2025, due primarily to $22.2 million of net income recognized for the quarter and a $2.2 million decrease in accumulated other comprehensive loss. These increases were partially offset by $8.2 million in dividends paid to common shareholders during the quarter.

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 December 31, 2025.

The following table summarizes the capital ratios for the Company at the dates indicated:

December 31,<br>2025 September 30,<br>2025

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 December 31, 2025 compared to 1.13% at September 30, 2025. The decrease in the ACL as a percentage of loans was due primarily to a change in the mix of loans due to decreases in the real estate construction and land development segment which has a higher ACL as a percentage of loans, offset by an increase in other segments with a lower ACL as a percentage of loans. During the fourth quarter of 2025, the Company recorded a $0.9 million reversal of provision for credit losses on loans, compared to a $1.6 million provision during the third quarter of 2025.

During the fourth quarter of 2025, the Company recorded a $95,000 provision for credit losses on unfunded commitments compared to a $212,000 provision during the third quarter of 2025. The provision for credit losses on unfunded commitments during the fourth quarter of 2025 was due primarily to a decrease in utilization rates.

The following table provides detail on the changes in the ACL on loans and the ACL on unfunded commitments ("ACL on Unfunded"), and the related (reversal of) provision for credit losses for the periods indicated:

Nonaccrual loans increased by $3.4 million during the fourth quarter of 2025 due primarily to the migration of three non-owner occupied CRE loans totaling $3.9 million, offset partially by principal payments received.

Net Interest Margin and Net Interest Income

Net interest margin increased 8 basis points to 3.72% during the fourth quarter of 2025, from 3.64% during the third quarter of 2025.

The yield on interest earning assets decreased one basis point to 5.03% for the fourth quarter of 2025, compared to 5.04% for the third quarter of 2025. The yield on loans receivable increased one basis point to 5.54% during the fourth quarter of 2025, compared to 5.53% during the third quarter of 2025 as new loans were booked and adjustable rate loans repriced at higher rates, partially offset by the impacts of the three fed funds rate cuts occurring during the last four months of the year.

The cost of interest bearing deposits decreased six basis points to 1.83% for the fourth quarter of 2025, from 1.89% for the third quarter of 2025. This decrease was primarily due to a decrease in certificate of deposit rates.

Net interest income increased $1.0 million, or 1.7%, during the fourth quarter of 2025 compared to the third quarter of 2025 due to a decrease in interest expense of $1.6 million, offset partially by a $0.6 million decrease in total interest income.

Net interest margin increased 36 basis points to 3.72% during the fourth quarter of 2025, compared to 3.36% for the same period in the prior year. Net interest income increased $4.6 million, or 8.6%, during the fourth quarter of 2025 compared to the same period in the prior year. The increase was due primarily to a change in the mix of earning assets to higher yielding loan balances and a decrease in deposit and borrowing interest expense due to lower rates and lower borrowing balances.

Noninterest Income

Noninterest income decreased $338,000 to $8.0 million during the fourth quarter of 2025 from $8.3 million during the third quarter of 2025. The decrease was due primarily to decreases in card revenue and a decrease in other income, offset partially by an increase in interest rate swap fees due to increased swap activity and an increase in bank owned life insurance ("BOLI") income due to the recognition of a death benefit.

Noninterest income increased $4.7 million during the fourth quarter of 2025 from the same period in 2024 due primarily to a $3.9 million loss recognized in the fourth quarter of 2024 resulting from the sale of investment securities as part of the strategic repositioning of the Company's balance sheet and an increase in BOLI income as the Company incurred $508,000 in costs related to the restructuring of the BOLI portfolio in the fourth quarter of 2024.

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

Noninterest Expense

Noninterest expense decreased $132,000, or 0.3%, to $41.5 million during the fourth quarter of 2025, compared to $41.6 million in the third quarter of 2025. Compensation and employee benefits increased due to an increase in the accrual for incentive compensation. Professional fees decreased due primarily to lower merger related costs recognized in the fourth quarter of 2025 associated with the acquisition of Olympic.

Noninterest expense increased $1.9 million, or 4.9%, during the fourth quarter of 2025 compared to the same period in 2024 due

primarily to an increase in compensation and employee benefits due to annual merit increases in base pay, an increase in benefit expense and incentive compensation expense accruals.

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

All values are in US Dollars.

Income Tax Expense

Income tax expense increased $305,000 to $3.4 million during the fourth quarter of 2025, compared to $3.1 million during the third quarter of 2025 due to an increase in pre-tax income.

Income tax expense and the effective income tax rate decreased in the fourth quarter of 2025, compared to same period in 2024 due primarily to additional tax expense of $2.4 million related to BOLI restructuring during the fourth quarter of 2024, partially offset by increased income tax expense on higher pre-tax income during the fourth quarter of 2025.

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

Such statements often include words such as "believes," "expects," "anticipates," "estimates," “forecasts,” "intends," “plans,” “targets,” “potentially,” “probably,” “projects,” “outlook” or similar expressions or future or conditional verbs such as “may,” "will," “should,” "would," and "could," as well as the negative of such words. Forward-looking statements are not historical facts but instead represent management's current expectations and forecasts regarding future events, many of which are inherently uncertain and outside of our control. Actual results may differ, possibly materially, from those currently expected or projected in these forward-looking statements. Factors that could cause our actual results to differ materially from those described in the forward-looking statements include, but are not limited to, the following: • potential adverse impacts to economic conditions nationally or in our local market areas, other markets where Heritage Financial Corporation (the "Company") and its subsidiaries have lending relationships, or other aspects of the Company’s business operations or financial markets, including, without limitation, as a result of credit quality deterioration, pronounced and sustained reductions in real estate market values, employment levels, labor shortages and a potential recession or slowed economic growth; • changes in the interest rate environment, which could adversely affect our revenues and expenses, the value of assets and obligations, and the availability and cost of capital and liquidity; • the level and impact of inflation and the current and future monetary policies of the Board of Governors of the Federal Reserve System in response thereto; • legislative or regulatory changes that adversely affect our business, including changes in banking, securities, and tax law, in regulatory policies and principles, or the interpretation and prioritization of such rules and regulations; • effects on the U.S. economy resulting from the threat or implementation of, or changes to existing, policies and executive orders, including tariffs, immigration policy, regulatory and other governmental agencies, DEI and ESG initiatives, consumer protection, foreign policy, and tax regulations; • credit and interest rate risks associated with the Company’s businesses, customers, borrowings, repayment, investment, and deposit practices; • fluctuations in deposits and deposit concentrations; • liquidity issues, including our ability to borrow funds or raise additional capital, if necessary; • fluctuations in the value of our investment securities; • credit risks and risks from concentrations (including by type of geographic area, collateral and industry) within our loan portfolio; • disruptions, security breaches, insider fraud, cybersecurity incidents or other adverse events, failures or interruptions in, or attacks on, our information technology systems or on the third-party vendors who perform critical processing functions for our business, including sophisticated attacks using artificial intelligence and similar tools; • technological changes implemented by us and other parties, including third-party vendors, which may be more difficult to implement or more expensive than anticipated or which may have unforeseen consequences to us and our customers, including the development and implementation of tools incorporating artificial intelligence; • increased competition in the financial services industry from non-banks such as credit unions and financial technology companies, including digital asset service providers; • our ability to adapt successfully to technological changes to compete effectively in the marketplace, including as a result of competition from other commercial banks, mortgage banking firms, credit unions, securities brokerage firms, insurance companies, and financial technology companies; • our ability to implement our organic and acquisition growth strategies, including the pending acquisition of Olympic Bancorp, Inc. (“Olympic”), and our ability to successfully integrate Olympic's customers and operations following the acquisition; • effects of critical accounting policies and judgments, including the use of estimates in determining fair value of certain of our assets, which estimates may prove to be incorrect and result in significant declines in valuation; • the commencement, costs, effects and outcome of litigation and other legal proceedings and regulatory actions against us or to which the Company may become subject; • potential impairment to the goodwill the Company recorded in connection with our past acquisitions, including the pending acquisition of Olympic; • loss of, or inability to attract, key personnel; • our ability to successfully integrate any assets, liabilities, customers, systems, and management personnel we may acquire, including as a result of the acquisition of Olympic, into our operations and our ability to realize related revenue synergies and cost savings within expected time frames or at all, and any goodwill charges related thereto and costs or difficulties relating to integration matters, including but not limited to customer and employee retention, which might be greater than expected; • the effects of climate change, severe weather events, natural disasters, pandemics, epidemics and other public health crises, acts of war or terrorism, foreign relations, and other external events on our business and the businesses of our clients; • the impact of bank failures or adverse developments at other banks and related negative publicity about the banking industry in general on investor and depositor sentiment regarding the stability and liquidity of banks; and • our success at managing and responding to the risks involved in the foregoing items. You should also consider the risks, assumptions and uncertainties set forth in the “Risk Factors” section in our Annual Report on Form 10-K for the year ended December 31, 2024, as well as those set forth in other reports we file with or furnish to the Securities and Exchange Commission (the “SEC”) which are available on our website at www.hf-wa.com and on the SEC's website at www.sec.gov.
