Cautionary Note Regarding Forward-Looking Statements This presentation contains "forward-looking statements" within the meaning of the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995. Forward-looking statements include, without limitation, statements concerning plans, estimates, calculations, forecasts and projections with respect to the anticipated future performance of Heritage Financial Corporation ("Heritage") and Olympic Bancorp, Inc. (the "Target") and certain plans, expectations, goals, projections and benefits relating to the merger of the Target with and into Heritage (the "Merger"), all of which are subject to numerous assumptions, risks and uncertainties. These statements are often, but not always, identified by words such as "may," "might," "should," "could," "predict," "potential," "believe," "expect," "continue," "will," "anticipate," "seek," "estimate," "intend," "plan," "projection," "would," "annualized," "target" and "outlook," or the negative version of those words or other comparable words of a future or forward-looking nature. Examples of forward-looking statements include, among others, statements Heritage makes regarding the ability of Heritage and the Target to complete the transactions contemplated by the agreement and plan of merger (the "Merger Agreement"), including the parties' ability to satisfy the conditions to the consummation of the Merger, statements about the expected timing for completing the Merger, the potential effects of the proposed Merger on both Heritage and the Target, and the possibility of any termination of the Merger Agreement. 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 management's control. Actual results may differ, possibly materially, from those currently expected or projected in these forward-looking statements. In addition to factors disclosed in reports filed by Heritage with the SEC, risks and uncertainties for Heritage, the Target and the combined company that may cause actual results or outcomes to differ materially from those anticipated include, but are not limited to: (1) the possibility that any of the anticipated benefits of the proposed Merger will not be realized or will not be realized within the expected time period; (2) the risk that integration of the Target's operations with those of Heritage will be materially delayed or will be more costly or difficult than expected; (3) the parties' inability to meet expectations regarding the timing of the proposed Merger; (4) changes to tax legislation and their potential effects on the accounting for the Merger; (5) the inability to complete the proposed Merger due to the failure of the Target's shareholders to adopt the Merger Agreement, or the failure of Heritage's shareholders to approve the issuance of Heritage's common stock in connection with the Merger; (6) the failure to satisfy other conditions to completion of the proposed Merger, including receipt of required regulatory and other approvals; (7) the failure of the proposed Merger to close for any other reason; (8) diversion of management's attention from ongoing business operations and opportunities due to the proposed Merger; (9) the challenges of integrating and retaining key employees; (10) the effect of the announcement of the proposed Merger on Heritage's, the Target's or the combined company's respective customer and employee relationships and operating results; (11) the possibility that the proposed Merger may be more expensive to complete than anticipated, including as a result of unexpected factors or events; (12) the dilution caused by Heritage's issuance of additional shares of Heritage's common stock in connection with the Merger; and (13) changes in the global economy and financial market conditions and the business, results of operations and financial condition of Heritage, the Target and the combined company. Please refer to Heritage's Annual Report on Form 10-K for the year ended December 31, 2024, as well as Heritage's other filings with the SEC, for a more detailed discussion of risks, uncertainties and factors that could cause actual results to differ from those discussed in the forward-looking statements. Any forward-looking statement included in this presentation is based only on information currently available to management and speaks only as of the date on which it is made. Neither Heritage nor the Target undertakes any obligation to publicly update any forward-looking statement, whether written or oral, that may be made from time to time, whether as a result of new information, future developments or otherwise.
