Heritage Financial Corporation (the" Company") intends such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in 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. These forward-looking statements are subject to known and unknown risks, uncertainties and other factors that could cause actual results to differ materially from the results anticipated or implied by 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 we have lending relationships, or other aspects of our 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 and executive orders in response thereto; • previous and potential future 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; • legislative or regulatory changes that adversely affect our business, including changes in banking, securities, and tax laws, in regulatory policies and principles, or the interpretation and prioritization of such rules and regulations; • effects on the U.S. economy resulting from actions taken by the federal government, including the threat or implementation of tariffs, immigration enforcement and changes in foreign policy; • the effects of acts of war or terrorism, foreign relations, military conflicts, including the wars in Iran and Ukraine and the military conflict between Israel and Hamas in the Middle East, and other external events on our business and the businesses of our clients; • credit and interest rate risks associated with our business, including our customers’ borrowing, repayment, and deposit practices; • fluctuations in deposits and the concentration of large deposits from certain customers, who have deposit balances above current FDIC insurance limits; • 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; • the effectiveness of our risk management framework; • rapid 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 recent 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 we may become subject, including in connection with prior acquisitions; • potential impairment to the goodwill we recorded in connection with our past acquisitions, including as a result of the recent 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 recent 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; • 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.
