**Item 8.01 &nbsp;&nbsp;&nbsp;&nbsp;Other Events.**

On June 25, 2026, FirstSun Capital Bancorp ("FirstSun," "we," "us," and "our"), the holding company for Sunflower Bank, National Association (the "Bank"), announced that the Bank completed the sale of approximately $336 million of performing municipal loans acquired from First Foundation Bank to an unaffiliated third party. The sale of municipal loans was contemplated and announced as part of our acquisition of First Foundation Inc. ("First Foundation"), which closed on April 1, 2026.

With the completion of the sale of municipal loans, we have now completed the balance sheet repositioning strategy that we announced as part of our planned acquisition of First Foundation. We intend to use the proceeds from the sale of municipal loans to pay down certain high cost brokered and non-brokered deposits acquired from First Foundation Bank. We expect our overall balance sheet repositioning, including loan downsizing, and total loan fair value marks, including marks related to loan downsizing, to be in line with our expectations disclosed at the time we announced our planned acquisition of First Foundation.

**Cautionary Note Regarding Forward-Looking Statements**

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 our expectations with respect to total loan fair value marks, including marks related to loan downsizing, and our intended use of proceeds from the loan sale. Words such as "expect," "intend," "believe," "will," "may," "anticipate," "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 possibility that the intended use of proceeds from the loan sale may change as a result of changes in economic conditions, market interest rates, volatility in the financial services sector; the impact of purchase accounting with respect to the acquisition of First Foundation, or any change in the assumptions used regarding the assets acquired and liabilities assumed to determine their fair value and credit marks; our integration of the business and operations of First Foundation may take longer or be more costly than anticipated; and other factors, many of which are beyond our control.

We caution readers that the foregoing list of factors is not exclusive, is not necessarily in order of importance and readers should not place undue reliance on any forward-looking statements. Additional 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 "Cautionary Note Regarding Forward-Looking Statements" and "Risk Factors" in our Annual Report on Form 10-K for the year ended December 31, 2025 and other documents subsequently filed by us with the SEC. 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.
