Forward-Looking Statements

This presentation contains, and from time-to-time in connection with this presentation our management may make, forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements reflect our views at such time with respect to, among other things, future events and our financial performance. These statements are often, but not always, made through the use of words or phrases such as "may," "might," "should," "could," "predict," "potential," "believe," "expect," "continue," "will," "anticipate," "seek," "estimate," "intend," "plan," "projection," "would," "annualized," and "outlook," or the negative version of these words or other comparable words or phrases of a future or forward-looking nature. These forward-looking statements are not historical facts and are based on current expectations, estimates and projections about our industry, management's beliefs and certain assumptions made by management, and any such forward-looking statements are subject to risks, assumptions, estimates and uncertainties that are difficult to predict. Further, statements about the potential effects of the COVID-19 pandemic on our businesses and financial results and conditions may constitute forward-looking statements and are subject to the risk that the actual effects may differ, possibly materially, from what is reflected in those forward-looking statements due to factors and future developments that are uncertain, unpredictable and in many cases beyond our control, including the scope and duration of the pandemic, actions taken by governmental authorities in response to the pandemic, and the direct and indirect impact of the pandemic on our customers, third parties and us. Actual results may prove to be materially different from the results expressed or implied by the forward-looking statements. Factors that could cause our actual results to differ materially from those described in the forward-looking statements, including (without limitation) the risks and uncertainties associated with the ongoing impacts of COVID-19, the domestic and global economic environment and capital market conditions and other risk factors, can be found in our SEC filings, including, but not limited to, our Annual Report on Form 10-K for the year ended December 31, 2021, and our Quarterly Reports on Form 10-Q for the

quarters ended March 31, June 30, and September 30 2022, which are available on our website (www.fhb.com) and the SEC's website

(www.sec.gov). Any forward-looking statement speaks only as of the date on which it is made, and we do not undertake any obligation to update or review any forward-looking statement, whether as a result of new information, future developments or otherwise, except as required by applicable law.

Use of Non-GAAP Financial Measures

The information provided herein includes certain non-GAAP financial measures. We believe that these measures provide useful information about our operating results and enhance the overall understanding of our past performance and future performance. Although these non- GAAP financial measures are frequently used by stakeholders in the evaluation of a company, they have limitations as analytical tools and should not be considered in isolation or as a substitute for analysis of our results or financial condition as reported under GAAP. Investors should consider our performance and financial condition as reported under GAAP and all other relevant information when assessing our performance or financial condition. The reconciliation of such measures to the comparable GAAP figures are included in the appendix of this presentation.
