Statements in this Current Report on Form 8-K which are not historical in nature are intended to be, and are hereby identified as, forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Examples of forward-looking statements include, but are not limited to, statements regarding the expectations of First Foundation and FirstSun with respect to the expected timing of the closing of the proposed merger. Words such as “expect,” “will,” “may,” “anticipate,” “intend,” “opportunity,” “continue,” “should,” “could,” and variations of such words and similar expressions are intended to identify such forward-looking statements. Forward-looking statements are subject to risks, uncertainties and assumptions that are difficult to predict with regard to timing, extent, likelihood, and degree of occurrence, which could cause actual results to differ materially from anticipated results. Such risks, uncertainties, and assumptions, include, among others, the following: the failure of either party to satisfy any of the remaining closing conditions on a timely basis or at all; unexpected delays in completing the proposed merger; the occurrence of any event, change, or other circumstances that could give rise to the right of one or both of the parties to terminate the merger agreement; the possibility that transaction-related costs, fees, or expenses may be greater than anticipated; the outcome of any legal proceedings that may be instituted against First Foundation or FirstSun; and changes in general economic, market, or financial conditions that could adversely affect the proposed transaction.

~~Proposal~~Additional 2:information concerning additional factors that could materially affect the forward-looking statements in this Current Report on Form 8-K can be found in the cautionary language included under the headings “Forward-Looking Statements” and “Risk Factors” in First Foundation’s Annual ~~merger~~Report ~~compensation~~on Form 10-K for the year ended December 31, 2024 and other documents subsequently filed by First Foundation with the SEC, ~~proposal~~including its Quarterly Reports on Form 10-Q. Further, any forward-looking statement speaks only as of the date on which it is made and we do not intend to and disclaim any obligation to update or revise any forward-looking statement to reflect events or circumstances after the date on which the statement is made or to reflect the occurrence of unanticipated events, except as required by law.
