Forward-Looking Statements

When used in this press release and in other documents filed with or furnished to the Securities and Exchange Commission (the “SEC”), other public stockholder communications, or in oral statements made with the approval of an authorized executive officer, the words or phrases “may,” “believe,” “will,” “will likely result,” “are expected to,” “will continue,” “anticipate,” “is anticipated,” “estimate,” “project,” “plans,” or similar expressions are intended to identify “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. 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 the Company’s actual results to differ materially from those described in the forward-looking statements, include, but are not limited to the following: adverse economic conditions in the Company’s local market areas, other markets in which the Company has lending relationships, or other aspects of the Company’s business operations or financial markets, including, without limitation, as a result of employment levels; labor shortages, the effects of inflation, recessionary pressures or slowing economic growth; credit risks of lending activities, including changes in the level and direction of loan delinquencies and charge-offs and changes in estimates of the adequacy of the allowance for credit losses; changes in interest rate levels and volatility, and the timing and pace of such changes, including actions by the Federal Reserve, which could adversely affect the Company's revenues and expenses, the values of our assets and obligations, and the availability and cost of capital and liquidity; inflationary pressures and related monetary and fiscal policy responses, and their impact on consumer and business behavior; geopolitical developments and international conflicts including but not limited to tensions or instability in Eastern Europe, the Middle East, South America, and Asia, or the imposition of new or increased tariffs and trade restrictions, which may disrupt financial markets; global supply chains, commodity prices, or economic activity in specific industry sectors; the effects of a federal government shutdown, debt ceiling standoff, or other fiscal policy uncertainty; increased competitive pressures, including repricing and competitors' pricing initiatives, and their impact on the Company's market position, loan, and deposit products; adverse changes in the securities markets; the Company’s ability to execute its plans to grow its residential construction lending, mortgage banking, and warehouse lending operations, and the geographic expansion of its indirect home improvement lending; challenges arising from expanding into new geographic markets, products, or services; secondary market conditions for loans and the Company’s ability to originate loans for sale and sell loans in the secondary market; volatility in the mortgage industry; fluctuations in deposits; liquidity issues, including the Company's ability to borrow funds or raise additional capital, if necessary; 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; the ability to adapt to rapid technological changes, including advancements in artificial intelligence, digital banking platforms, and cybersecurity; legislation or regulatory changes, including but not limited to shifts in capital requirements, banking regulation, tax laws, or consumer protection laws; vulnerabilities in information systems or third-party service providers, including disruptions, breaches, or attacks; environmental, social and governance matters; the effects of climate change, severe weather events, natural disasters, pandemics, epidemics and other public health crises, acts of war or terrorism, domestic political unrest and other external events on our business; and other factors described in the Company’s latest Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, and other reports filed with or furnished to the SEC which are available on the Company's website at www.fsbwa.com and on the SEC's website at www.sec.gov.

Further, statements about the effects of the Company's acquisition of Pacific West, completed on August 19, 2026, on the Company's business, financial results, and condition may constitute forward-looking statements and are subject to the risk that the actual effects may differ, possibly materially, from what is reflected in the forward-looking statements due to factors and future developments which are uncertain, unpredictable, and in many cases, beyond the Company's control, including the following: the expected cost savings, synergies and other financial benefits from the merger might not be realized within the expected time frames or at all; the integration of the combined company, including the conversion of operating systems and the retention of key personnel and customers, might not proceed as planned or may be more difficult, time-consuming or costly than expected; merger-related and integration expenses may be greater than expected; preliminary estimates of the fair value of acquired assets and assumed liabilities may change during the measuring period, and acquired loans may experience higher credit losses than anticipated; and the combined company might not perform as well as expected.

Any of the forward-looking statements that the Company makes in this press release and in the other public statements are based upon management's beliefs and assumptions at the time they are made and may turn out to be incorrect because of the inaccurate assumptions the Company might make, because of the factors illustrated above or because of other factors that cannot be foreseen by the Company. Therefore, these factors should be considered in evaluating the forward‑looking statements, and undue reliance should not be placed on such statements. The Company does not undertake, and expressly disclaims any obligation, to update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise, except as required by law.
