INVESTOR PRESENTATION Q3 2025
2 This presentation contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. 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") has 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 (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 Fintech 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”); • 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; • the effects of climate change, severe weather events, natural disasters, pandemics, epidemics and other public health crises, acts of war or terrorism, 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. These risks, assumptions and uncertainties should be considered in evaluating any forward-looking statements, and undue reliance should not be placed on such statements. Any forward-looking statement speaks only as of the date on which it is made, and the Company undertakes no obligation to update any forward-looking statement, whether to reflect events or circumstances after the date on which the statement is made, to reflect new information or the occurrence of unanticipated events, or otherwise.

Non-GAAP Financial Information The Company reports its results in accordance with United States generally accepted accounting principles (“GAAP”). However, management believes that certain non-GAAP performance measures used in managing the business may provide meaningful information about underlying trends in its business.
